Research Proposal Draft - Essay Example There are also few studies that indicate the way in which these youngsters can be motivated to adopt a positive lifestyle in terms of being physically active and eating the proper diet that will help them to avoid obesity. There exists a desperate need to identify a connection between the benefits that come with weight loss. There is also a need to make sure that people, especially the young people are not only aware of the health benefits of losing excess weight but that they are motivated to lose the excess weight through positive lifestyle and the proper eating habits. The significance of the current research study is to measure how a quantitative weight loss program will affect those who will be involved in the study. The study will involve 50 participants of ages between 8 and 18, from both the genders. All the participants have to have a body mass index of over the 95th percentile which is a clear indication that they are obese and overweight. The study will be done in a period of twelve weeks. The study will monitor food intake, oxygen saturation, blood pressure, heart rate, blood glucose and cholesterol levels of the participants. Will there be increased positive health benefits such as, improved oxygen circulation, healthy blood pressure, heart rate, blood glucose and cholesterol levels, in the participants who will be children age 8 to 18 with a BMI above the 95th percentile? The hypothesis for this research is that there will be clear indication of the positive health outcomes that will be achieved by the 50 participants who will be involved in this controlled medical study for weight loss. Needles to say, age is an important factor when weight related health issues are being considered. The way an 8 year old child can be affected by overweight may not be the same way s an 18 year old will be affected. At the same time, the way an older patient may be able to stay in course in a controlled weight loss progress is not the same way a young

I would like to express my deep gratitude to my supervisor, Mr. Mohd Khanapiah Bin Nor for guiding me to complete this project. He was giving me necessary information regarding the project and a lot of inspiring ideas. My appreciation also gives to my beloved parents, family members, and friends who have been behind me throughout this project for the encouragement and supported from them. I really appreciate all their help and support while I’m completing this project. Lastly, I would like to sincerely thank Universiti Teknikal Malaysia Melaka (UTeM) for providing the facilities and equipment for me to complete my project. In the previous era, the technology application mostly using wire but now a wireless device has become commonplace. The wireless sensor network can be defined as an application that having no wires connection on that devices. In addition, to make the system easy to monitor from a distant location, the RF 433MHz module was used. So, this project gives the idea for studying details about the RF 433MHz module performance for WSN application. 1.1 Project Background Nowadays, using the wireless sensor network (WSN) technology to monitor the environment helps someone to solve the problems of deployment difficulty, high cost, and realized unmanned monitoring which is mostly used in a factory, buildings, laboratory, and house. This project is to study the range and performance of the RF 433MHz module for WSN application. RF 433MHz module is popularly used in the remote control system. This range also available to use in this area. There are two types of the RF module which is transmitter and receiver. From research, using RF 433MHz module, the data can get more accurately without any data losses with the range that given than compared to another transmission for the wireless sensor network. The range that can reach by this RF module is different between outside and inside area. For inside area, it can work for 50 meters through multiple walls with an antenna, while for the outside area, it will be able for hundreds of meters. Besides that, a microcontroller such as Arduino also used in this project. Arduino that available for this project is Arduino PRO which is it has 3.3V port that will be easier to connect directly to the types of RF 433MHz module that used in this project. This project also will be studied the analysis of the data transmission by giving a few of distance between the transmitter and receiver of the RF 433MHz modules when located in the obstacles or line of sight area. Then, the data that are received will be displayed on the computer whether there are data losses or not. The problem that becoming as issues right now is there is a lot of ways to send data but the problem is about the range, cost, and data losses. So, for this situation, study the performance of RF 433MHz can overcome the problem for the WSN application. The objectives of this project are to understand the range and performance of RF 433MHz module. Moreover, exploration about the transmitting and receiving the data by using the RF 433MHz module. The main work scope of this project is to make sure this project will achieve the objectives. The main focus of this project:- i. To study and understanding the range of RF 433MHz module. ii. To transfer data by using RF 433MHz module. 1.5 Methodology In this project, there is three part that needs to follow. For the first part, it will be focused on the conducting the literature review and do some research more detail about the RF 433MHz module. Meanwhile, for the second part, after the software development process, the hardware development process will take over and include the testing of the project. Last part, when the hardware and software complete their part, it will be followed by testing the performance and the operation of the project to make an analysis. The methodology is the explanation of the procedures or steps when doing this project. The simulation, analysis, and evaluation of the project. A literature review is an important step before proceeding to the project. Collecting all the required information about the 433MHz RF module from the books, journals, and website. The literature review also can provide a useful information to complete the project. The idea for this project comes from the problem faced when the data that have been transmitted becomes losses with the range that provided. In this chapter, it will be explained more details about the project and also the components that will be used in this project. The frequency of 433MHz that used in the wireless sensor network can test the sending and receive the data for this range without any data losses. 433MHz RF modules required the 17cm of the antenna to support the range to send the data. The range is one of the most important parameters of any wireless system which is it defined how the transmitter and receiver can be apart from each other to send the data. A range of the outside with few obstacles the data can go through hundreds of meters. While for the indoor, the data can go over 50 meters through multiple walls. The external antenna will be soldering to the â€Å"ANT† on the transmitter to get more range which is 17cm of the length of the antenna that was used. Regarding the several research that I have done from a few of journals that can relate to my project. Wireless sensor networks are currently widely used in several of monitoring and control applications. Guohua Yang and Kui Zhang (2015) have conducted a project regarding the 433MHz radio for long-range communication. They present about the connectivity, range of the communication and packet loss ratio that have been performed in the indoor and outdoor environment. The Maarten Weyn and Glenn Ergeerts (2013) conducted the survey of the DASH7 Alliance Protocol for wireless sensor network (WSN). In this research, it stated that 433MHz is an unlicensed band. They said that, due to the frequency, it has a better propagation characteristic opposed to the higher frequency. The wavelength at the center of frequency is 69.14cm which is the bandwidth for the frequency is 1.84MHz. This limits the data rate of the communication at this frequency 433MHz is an ideal for low power of low data rate communication. Budi Setiyono, Sumardi, and Rafdito Harisuryo (2015) have conducted a project on measurement system of temperature, humidity and air pressure over 433MHz radio frequency for an application on a quadrotor. They using the telemetry system which is the measurement process of data at a certain distance. Then, they stated that data will be processed or analyzed by the receiving station. They stated on their result which is for successful transmission, the amount of data that received will be same as the amount of data that have been sent. This project is to improve the data transmission with 433MHz RF modules either in obstacles or line of sight condition. The 433MHz RF modules are categorized as the lower cost, lower power consumption and the most important is when the longer the distance for data that transmit remains accurate when it received by the receiver. In theoretical, the success of data transmission is the amount of data received will be same as the data that have been sent. That means there are no data losses when the transmission occurred. Radio Frequency (RF) is a rate in the range of around at 3 kHz to 300GHz which is corresponding to the frequency of radio waves, and the alternating current that can carry the radio signals. ITU bandstand for International Telecommunication Union that defined for the electromagnetic frequencies that used for radar and radio. The best set of terms for frequencies used in communication. While the very lowest bands have no radar applications. The table below shows the frequency range and ITU band. The Arduino Pro is a microcontroller board based on the ATmega328. This microcontroller is an open-source hardware and software. The version that used in this project is 3.3V/8MHz. This version can be powered by a battery or external power supply. It has 14 digital inputs and output pins which is 6 of it can be used as PWM output, another 6 pins for the analog input, battery power jack, an ICSP header and reset button. Arduino Pro needs to connect with FTDI cable through six pins header to provide the USB power and have a communication with the board. Arduino Pro has the port for 3.3V that can supply the voltage for the transceiver. Each of the 14 digital pins on the Arduino Pro can be used as an input and output which is operated at 3.3V. Each of the pins can provide or receive a maximum of 40mA and has internal pull-up resistor (disconnect by default) of 20 until 50 kohm. The ATmega328 has 32KB and running 8MHz of the external resonator. It also has 2KB of SRAM and 1KB of EEPROM that can read and written with the EEPROM library. The operation of the Arduino microcontroller is based on the connection made on the pins. The application can be done by using the Arduino software where Arduino function can be edited according to the applications in this software. This software can work on by using the C or C++ language. The program that has been creating the need to upload to the microcontroller by using the USB cable. If there is an error detected on the program, it will be adjusted by editing to make a correction on the process and then the program needs to reload again. Other than that, there is another option which is using the reset button to delete all the previous program that have been upload before this to make it clear then built again. MHz RF Module version that has been used. It is because can operates in the unlicensed ISM (Industry Science and Medicine) radio band. It’s available for use in the inexpensive area for short-range wireless networks of sensors. This types can operate on the 433MHz frequency and can capable of transmitting at up to 100mW and up to 300kbps. When increasing the transmit power and reducing the data rate it can maximize the range of the 433MHz. DHT11 is a digital temperature and humidity sensor. Its suitable for my project that only needs to read the data about the temperature and humidity only. Micro-B is the smallest USB connector type. This type also used for the android as a cable for charging while USB port A is that can connect to PC or laptop. This USB cable needs to connect the RF transceiver module with the Arduino Pro at the transmitter and receiver. Using this board because the standard FTDI board cannot supply the enough current to run the RFM69 433MHz RF Modules. The difference between standard FTDI and Beefy 3 FTDI is the current that can provide which is standard FTDI provide 50mA while Beefy 3 FTDI provides up to 500mA. This chapter will be discussed the procedures and steps that used in this project. Each of the methods that were used to achieve this project will be stated and explain briefly. The purpose of the methodology is used to achieve the objective that has been stated. 3.1 Software Design In this part, the software design is part to do the programming by using the Arduino software. The flow of the data transmission starting from the reading of the temperature and humidity by using the DHT11 sensor. Then, the data will be processed by a microcontroller. It will be sent through the transmission of data by using the 433MHz RF transmitter module. When the power supply is turned on, the 433MHz RF receiver module and the microcontroller ready to accept the data that have been transmitted. After that, the data is sent by the Arduino microcontroller via a serial port to the computer for displaying the data. Based on Figure 1 and Figure 2 it showed the flow how it works. Hardware design consists of two parts which are from here it will be explained how the flow of the project will be complete. For the first part as shown in Figure 3.3 is the data obtain from the DHT11 sensor reading, then the data will be transmitted by the 433MHz RF transmitter modules. While for the second part as shown in Figure 3.4 is the data received via 433MHz RF receiver modules then sent by the Arduino PRO that connected to a computer for display. The generated data for this project should be the same with the theoretical results. Besides that, the results of this project will be compared with the theoretical results, the journals or book that have been found.

The Future of On-line Journalism Essay -- Exploratory Essays Research

The Future of On-line Journalism Interactivity is what most separates on line news from traditional news. Indexicality (using hypertext links) is an important aspect of on-line journalism because it frees up space and time for the reader. People can explore international news and easily access the latest stories before the papers get to print, all at the click of a mouse. Many studies have been done on how people use web services. One of the major characteristics of such use is searching through different hyperlinks. Hypertext enables people to see things through new dimensions. Online journalists have to be innovative in the way they create news. "Transparent journalism," allowing readers to participate in the writing, is one example of how journalists are adapting to the on line form. "Eye track" (equipment that monitors where people's eyes focus and for how long) studies have also been useful in studying how we use the web. These studies will help news organizations and rest of us in understanding twenty-first century communication.

Mastering Audio

The History of â€Å"Mastering† Music, in most of its styles and forms that is targeting commercial distribution now undergoes a final process of transformation and quality verification known as Mastering. For those working within the audio industry, this process is an unavoidable step to pass through. The role of the mastering engineer is almost unknown and often unheard of.This status of the mastering process has over the ears gathered itself an almost mythical status in the industry. The art itself is quite often misunderstood and in certain cases considered unimportant. Through this essay I hope to explore further into the role of the mastering process and the position it has held over decades with changes in styles, technology and mediums of media distribution. â€Å"Mastering is the set of activities in the audio chain between the final production of the music on an intermediary format and its transfer to a distribution format. (Dominique Bassal, 2005) During the early days, the process of mastering was not a separate discipline that as followed by a different engineer. A recording engineer's profile would involve recording onto a disc cutting lather. Before the year 1925, the tools used to cut records was unsophisticated and worked in a fairly mechanical manner without the use of electricity. By the 1930's the advent of electricity in the audio industry like many other markets changed the way media was recorded, processed and finally distributed.The rise of the radio stations, microphones and the amplification of the stylus that was previously driven Just by a diaphragm into an acoustical horn has changed the way mastering works. The discs cut onto wax were used as stampers to press 78rpm discs using shellac-composite. This was the method of cutting/ producing records before the advent of tape. Mastering/cutting Engineer Post the second world war, the recording ot tape and micro groove LP were tlrst introduced. The introduction of tape recording changed the norm of master recordings almost always being cut direct to disc.This was the beginning of a separate engineer being in charge of using the session tapes to cut master discs. This person was not initially known as a mastering engineer but a â€Å"dubbing ngineer† or rather â€Å"transfer engineer†. â€Å"mastering was a black art practiced by technical curmudgeons who mysteriously made the transfer from the electronic medium of magnetic audio tape to the physical medium of vinyl. † – (Owsnski, 2007) This change brought about the industrial belief that the process of cutting the master discs from recording session tapes was not a very different technical skill than the vinyl pressing operation.The biggest problem as such with vinyl has been to safeguard the largest possible part of the audio fidelity of the master tape, by troubleshooting and working around he numerous downfalls and obstacles brought about by the medium itself. The technology o f cutting vinyl from tape came with its own set of limitations to a huge degree. To explain the groove on the record, the thickness of the hair carries pitch and tonal information laterally and the amplitude information vertically. The problems brought about by this system was that the bass frequencies would drastically affect the total width of the groove.This in turn would affect the determined length of the information being cut onto the vinyl. the thickness of the vinyl similarly affected the dynamic range available for each cut. The recording onto analog tape helped with these flaws to a certain extent through having a tendency to roll off the distinctly sharp high intensity transients. This tendency was due to the saturation that occurred when hit with too much level, which would result in the stylus Jumping out of groove or often burn the disc cutter head itself.Around this time larger record companies dealing with pop music were prioritizing the automation of the tape to dis k transfer as much as possible in the interest of production efficiency. One of the biggest advancements this brought about was the ossibility to determine the thickness of the grooves using analog computer circuitry. It eventually brought about the possibility of having record sides of up to, and in some cases beyond, 30 minutes. The equipment being used for the mastering process also had to be specifically developed for use in record production.The idea behind this was to protect the companies from the expensive cutter heads blowing up as well as to ensure a more quality consistent product.! The birth of the Mastering Plant It was not long betore a tew engineers in this industry realized that there might me a arket out there for mastering that is done with superior care and skill. This brought about the birth of the first independent mastering lab in Los Angeles during the late 60's. The art of mastering became more about the attention to detail, skillful use of the highest grade equipment available and a devotion to artistic satisfaction.This trend soon grew into a business where a master tape sent to a mastering plant run by a credible engineer such as Bob Ludwig, Doug Sax or Bob Katz would result in a disc that sounded phenomenal. lt was during this time that the name of the astering engineer was listed on to the credits of the albums. Mastering trivia: ! â€Å"A significant step in this extension of the role of the mastering engineer, even if ephemeral and exclusively linked to a specific musical style, was the dance mix fad, today devolved, in a modified form, to the D].A rhythmic pop song is delivered to the mastering studio with, along with its official mix, a series of excerpts, sub-mixes of rhythm sections, solo voices, etc. The mastering engineer constructs an extended version of the song, destined for, among others, nightclubs, adding as required upplemental effects and even sounds from other sources. † (Dominique Bassal, 2005) Mastering to day Mastering is still very much a part of the industry, although most of them no longer cut master discs from analog reel tape. The CD generation has definitely caused a huge change in the mastering process.This process is now known as mastering where the recording in its final stage is brought in recorded on to a digital medium and is then sent for pressing. In the older days, each record company would have its own in house engineers working to a pre determined standard set by the company itself. These standards ere for the calibration of recorders, level and metering standards, interfacing and conversion equipment, etc. A number of engineers would also custom build some of the equipment used in their studio. This time saw that the tapes that were sent to these mastering studios could have a consistency to quality and fidelity.The order of the songs on the record, short pauses between tracks and equalization would have already been dealt with. ! Today the mastering business is a v ery different market compared to back then. The material for an album made these days could have been sourced from a variety of ifferent places, ranging from large studio rooms to a bedroom studio. The mixing on the record could have been done using Just a computer and sometimes by the artist themselves. These changes make it a completely contrasting market to when the big record companies were around.It opens a new realm of artistic space to play with as well. This treedom however also attec ed t the technical aspects ot the production. ! It is due to these reasons that mastering engineers began to expect their clients to provide them the recorded and mixed product with certain measures taken into account. The client is requested to not finish aspects of the process such as song spacing, fades and final master levels for each song. It is in the benefit of the client to trust the mastering engineer to take care of such detailed aspects with the necessary skill set and experience.A f undamental point to remember in todays technological free market is that technical competence cannot be taken for granted. Todays mastering engineers are expected to take a body of work that is recorded, produced and mixed and transform it into a sonic piece that is well balanced and is aurally pleasing to listen to. It involves a meticulous binding, processing and reinforcing of sound to translate the artistic vision onto various forms of playback. Mastering Equipment The equipment used in the process of mastering is a range of extremely high quality units that perform very specific tasks in the overall chain.The most important tool however is and will always be the attention to detail through years of experience and critical listening. Equipment used at this stage today is very relative to what is being achieved through the process itself. The aspects that are of prime importance through mastering are he conversion of audio information from analog to digital domains, the consisten t but not squashed dynamic range, equalization and balance of the songs with respect to each other and the intricately combined amplification done using consoles, compressors and limiters.Acoustics: Mastering is the last and final stage between the product and its dispatch for replication and distribution. This is where the sonic fidelity of the album or any other work is Judged technically to suite the various listening conditions and environments that audiences consume music in. Acoustics is amongst the most important tools to chieving a neutral space where the engineer can fully understand the strengths and weaknesses of the pre master. Monitors: Reference monitoring systems for mastering plants are very different from the ones used in the mixing and play back stages.Monitoring systems for mastering rooms can be two way or three way systems that divide the trequency ranges to separate drivers so that they are individually emphasized to then pay special attention to. Plants usuall y run two or three sets of references. Adam audio, Barefoot sound and Earthworks are some of the biggest names in Audio reference monitors for astering. Amplification: Amplification is an important stage in the mastering chain and is integral to driving the sound clean and transparent through and out of the monitors.Another reason for amplification is to have a palette of colors to pass the audio through. There are usually at least two different amplification systems in a mastering plant. Console: The console is the heart of the mastering chain where everything comes together. It is the Hub for the audio that is passing through the outboard equipment, convertors and the DAW. Manley, TK Audio and Maselec are highly renowned mastering console anufacturers. DAW: DAWS are the software environments within which the Audio is contained and worked with.There is a wide variety of programs that specialize in different need of the mastering process, For example – Pro tools HD, DDP creat or Pro, Sequoia. EQ's: Equalization is the process of treating specific ranges of the audio to strike a smooth balance that will translate the music onto systems that may not always reproduce the entire spectrum from 20Hz to 20KHz such as earphones and car audio systems. Buzz Audio, Prism Sound and GML are amongst the biggest names for EQ's with regards toDynamics processors: Dynamic range is an integral part of preparing music and audio to a level of industry standard distribution. These processors are categorized into Compressors, Limiters, Exciters, Expanders and Gates. They are used to gradually make the audio translate with a benchmark RMS and Peak level that varies in ratio across music, film, television and radio broadcast. Manley, Cranesong, API and Tubetech make extremely high grade Hardware Dynamics processors for mastering. Convertors: Convertors are arguably the most important tools in the mastering chain today.The amount ot media that is generated completely in the digi tal domain is significantly huge. Converting this information to analog in order to be processed and worked with requires precision based high quality convertor components that can be very expensive. The conversion process also plays a huge factor in converting analog to digital considering the fundamental differences that exist between them such as hardware circuitry and software coding. Lavry Engineering and Apogee is at the forefront of building high quality convertors for mastering. Digital Processors:An integral part of todays Mixing and Mastering is Digital Signal Processing. The tools available for use within a computer are much more cost effective and pretty close to replicating the results of analog gear and circuitry. The biggest names that have been developing the tools of this digital era are Universal Audio, Waves and McDSP, using modern technology and specifically designed chipsets to treat audio without losing its fidelity. Conclusion: The art of Mastering as a discip line was first considered to be a technical process within the larger process of making a record.Over the decades this art form came to recognition when its artistic impact was noticed by people from the industry such as the artist and producers themselves. This brought about the Mastering Plant Revolution. The skill set and aesthetic value brought into the production process by mastering engineers have grown to be invaluable in this day and age of digital distribution. It is through this evolution across almost five decades that todays mastering studio serves as the last and final stage of technical and artistic quality control for most recorded media.

Play And Physical Health Essay

Play is characterized by behaviors that are intrinsically motivated and self initiated. It is a process oriented, non-literal and pleasurable activity. it also has other characteristics as being exploratory, among other things (Fromberg, 2002). Play is an encompassing activity that affects the physical (Frost et al. 2001), social (Murata & Maeda, 2002), emotional and cognitive development of the child. (Murata & Maeda, 2002) Children spend an ample of their time playing. Children interact with their peers and parents most time by playing with them. A lot of their interaction with their parents builds their intellectual prowess. They learn to build social bonds with their family. (Rivkin 1995) . Moreover, interacting with their peers help them to become individuals that are completely incorporated into the society. Interaction with their colleagues sometimes brings about traumatic experiences like inflicting bodily wounds. The effect of what they do might linger with them for the rest of their lives. However sweet the playing experience could be, it can also be nasty. Aside from sharpening the physical and mental agility of a child, playing can also bring upon them serious medical emergencies as a result of accidents. Although play is an important part of sociological interaction, it is one of the major ways by which children learn role playing. Playing is also a way by which children keep themselves healthy. (Murata & Maeda, 2002) Play is good for the children but in order for it to bring out the desired results, it must be in the right environment (Rivkin 1995). The environment must be attractive enough to facilitate the play so as to encourage the action. In selecting play objects for children, it is important to consider their abilities and temperament so as not to inadvertently hand them tools that they can use in inflicting bodily harm to themselves and their peers. Also, they must play under the supervision of an older adult to monitor their activities. Play is pleasurable, it is good for the development of the child but it must not be allowed to get out of hand.

The Case Against Capital Punishment essays

The Case Against Capital Punishment essays Whitehead 1 A Moratorium on The Death Penalty Should Be Enacted In Illinois Due to the recent releases of newly exonerated Death Row inmates, individuals and organizations are calling for a moratorium- a cooling off period for state executions. The cases of just a few inmates makes it apparent that this would be a necessary step to save innocent lives. After 17 years in prison, Illinois Death Row inmate Anthony Porter was released from jail after a judge threw out his murder conviction following the introduction of new evidence. This reversal of fortune came just two days before Porter was to be executed. As reported in USA Today, Porter's release was the result of investigative research as conducted by a Northwestern University professor and students. The evidence gathered suggested that Porter had been wrongly convicted. Were these new revelations and the subsequent release of Porter a lucky break or a freak occurrence? Not likely, reports DeWayne Wickham, also of USA Today. He points out that since the reinstatement of the death penalty in the United States in 1976, of those sentenced to death, 490 people have been executed while 76 have been freed from Death Row. This calculates into one innocent person being released from Death Row for every six individuals that were executed. This figure correlates with the 1996 U.S. Department of Justice report that indicates that over a 7-year period, beginning in 1989, when DNA evidence in various cases was tested, 26% of primary suspects were exonerated. This has led some to conclude that a similar percentage of inmates presently serving time behind bars may have been wrongly convicted prior to the advent of forensic DNA typing.

Informative Essay Sample on Social Management System Changes If the statement man is a social animal is true then this management principal would be the best possible relevant example of it. Consider this- every individual is shaped by the virtue of his or her environment (Lamb, 23). Therefore it is obvious that an employee would be governed by the nature of workplace he or she is associated with. If the term work culture should be taken into account then it becomes more relevant. In most of the third world country red tape vicious circle is a usual nuisance under bureaucratic formulations. (Fletcher, 72) But to overcome it if anything is to be done is the entire reconstruction of the system itself. The governing body must make sure to provide the employees with a structure that motivates and accelerates the work efficiency of the employees. Likewise, this management principal could be an enormous resourceful tool for a HR manager who wants to gear up the efficiency level of the employees. If otherwise, the management decides that system is running smoothly and there are no needs to evoke a revolution in terms of system change, still the HR manager is left with ideas that would enable sea change within the work attitude of the employees by enforcing minor or petite changes within the set principals of the apparently rigid structure of the system. For example, the HR manager can introduce the use of low volume light music to be played though out the working hours. This music can be anything on the path of Kenny G saxophone or Richard Clayderman piano tunes. This would be a direct influence on the employees as light music like these would help them overcome boredom and attain more and refreshed vigor at work. (Podolski, 241)
