Assessment Of Equipment Diagnostic Radiology Health And Social Care Essay
Handiness and the usage of X-ray equipment in both private and authorities infirmaries is on the addition today in developed and developing states. Quality control of such equipment is of peculiar importance to forestall evitable high doses, radiation escapes and to guarantee dose optimisation. The consequences of quality control in this survey indicate that the end product measured in GHL ( M2 ) ranged between 0.0318 and 0.1192 mGy ( ma ) -1, while comparatively higher values which ranged from 0.0762 to 0.2156 mGy ( ma ) -1 was found in four other infirmaries. The tubing electromotive force truth measured indicates fluctuation among the infirmaries investigated. The divergence in electromotive force truth ranged between 0.9 and 10.9 % in the two units of GHL ( M1 and M2 ) . In the three other infirmaries the scope of divergences are 0.2 to 0.5 % ( PSH ) , 45.5 to 72.7 % ( NOH, the highest ) 22.9 to 23.3 % ( NARH ) . Both GHL ( M1 ) and PSH complied with the demand of à ± 5 % . As r egard timer truth, one-dimensionality of the tubing current and beam alliance ; NOH and NARH exceeded the acceptable bounds of à ±5 % , à ±10 % and à ±3 % severally. The effect of non-compliance in most portion include: repetition exposures, more disbursals and more significantly, extra dosage to the patient.Keywords: Quality confidence, quality control, environmental monitoring, radiation, X-ray end productIntroductionIn Nigeria, X-rays is the most often used ionizing radiation in medical specialty despite progresss in magnetic resonance imagination and ultrasound techniques. It has maintained a cardinal function in diagnosing of diseases, hurt and in X-ray therapy. In consequence it is the largest manmade beginning of ionising radiation to the universe population ( ICRP, 1991 ; UNSCEAR, 1993 ; Muhogora and Nyanda, 2001 ) . X ray is the major subscriber to the effectual dosage of both the patient and the forces. Because of the radiological hazards involved, it is normally recomm ended that dosage to patient from X-ray be kept every bit low as moderately accomplishable ( ALARA ) with equal image quality ( IAEA, 1996 ) . In add-on, programmes for diagnostic imagination sections, irrespective of the size, should at least contain the undermentioned constituents: equipment quality control, administrative duties, hazard direction and radiation safety programme. Equipment quality control unit carries out rating of equipment public presentation to guarantee proper image quality, every bit good as patient and operator safety ( Papp, 2002 ) . Furthermore, radiation safety unit is to guarantee that patient exposure is kept every bit low as moderately accomplishable and that departmental forces, medical staff and members of the general populace are protected from overexposure to ionising radiation. Presently, there are far above 4000 X-ray machines in Nigeria ( Elegba, 2006 ) out of which less than 5 % are under regulative control. These thereby pose a great jeopardy to the patient, forces and challenges to the regulative organic structure in Nigeria. As a consequence of handiness of X-ray installations, some new while others are 2nd manus ( known locally as Tokunbo ) , there has been a changeless addition in the figure and frequence of X-ray scrutinies in recent times. In Northwestern part of Nigeria for illustration, a study of 124 establishments with beginnings of ionising radiation indicates that 203 X-ray installings were found with merely 90 sealed radiation beginnings ( Mallam et al. , 2004 ) . In the same study, Ahmadu Bello University Teaching Hospital ( ABUTH ) complex on norm carries out over 250 diagnostic X-ray scrutinies per twenty-four hours in the three infirmary installations located in Zaria, Kaduna and Malunfasi. The population of the open persons and the fre quence of exposure is an indicant that one-year collective dosage to patient can be rather important. The quality control ( QC ) programme comprises the regular testing that must be carried out on each major constituent of the system to guarantee optimal public presentation within the system ( West,1993 ) . In diagnostic radiology QC trial is carried out to guarantee that a high quality diagnostic image is produced for a minimal radiation dosage to the patient ( NRPB, 1988 ) . The major equipment in diagnostic radiology to which quality control can be applied include X-ray production, sensing, image processing and image viewing equipment among others. The equipment testing is coupled with everyday environmental monitoring and appraisal of image quality ( Oluwafisoye et al. , 2009 ) .( 1.1 ) Nigerian Nuclear Regulatory Authority ( NNRA )Due to the hurtful effects of ionising radiation, the Nigerian Nuclear Regulatory Authority ( NNRA ) was established by the Nuclear Safety and Radiation Protection Act of 1995. This national regulative organic structure is charged with primary duty of atomic safety and radiation protection. The Act empowered the NNRA to categorise and licence activities affecting exposure to ionising radiation in peculiar, the ownership, production, processing, industry, purchase, sale, import, export, managing, usage, transmutation, transportation, trading, assignment, conveyance, storage, and disposal of any radioactive stuffs, atomic stuffs, radioactive waste, and any equipment breathing ionising radiation. In this respect, the NNRA in her papers made proviso for minimal demand for the equipment care in line with international regulative policies. As portion of the attempt at heightening safety in the usage of ionising radiation in Nigeria, the National Institute of Radiation Protection and Research ( NIRPR ) was established under the counsel of NNRA. The Institute trains forces in the radiation protection. The present measurings were conducted to look into the suitableness of the quality control trials and the stated tolerance degrees for assorted X-ray equipment at four Nigerian infirmaries. Additionally, environmental radiation supervising around the installations was carried out to determine the safety degree of both the patient and forces.( 2 ) MATERIALS AND METHODSQuality control trial ( kVp truth and duplicability, mAs one-dimensionality ) of four government-owned infirmaries, one general infirmary ( GHL ) , two specializer infirmaries [ Psychiatric infirmary ( PSH ) and National Orthopaedic infirmary ( NOH ) ] and one military infirmary ( NARH ) , all located in Lagos were carried out. The GHL has two functional X-ray units depicted as machine 1 ( M1 ) and machine 2 ( m 2 ) . The probe was carried out with the aid of the staff of the radiology section of each infirmary. Meanwhile, each of the X ray installations was used for both pediatric and big scrutinies. In all the infirmar ies there was no old exposure and QC informations available. The information use was done utilizing Microsoft Excel, 2003.( 2.1 ) Measurement of X-ray tubing Output and exposure clip merchandiseX-ray tubing end product is the sum of exposure, in millirontgens ( Mister ) delivered to a point in the Centre of the utile X-ray beam at a distance of 1 meter from the focal topographic point for 1 ma of negatron passing through the tubing. The end product expresses the ability of the tubing to change over electronic energy into X-ray exposure. X-ray tubing end product is the individual most of import parametric quantity to quantify radiation output ( Zoetelief et al, 2006 ) . The free-in-air exposure, FAE ( Mister ) was measured utilizing mill calibrated KV metre ( US made Victoreen X-ray trial device, theoretical account 4000 M+ ) obtained from the Department of Physics ( DOP ) University of Ibadan. The consistence of X-ray tubing end product with the tubing current ( ma ) or tube current exposure-time merchandise ( ma ) was measured for the scope of ma or ma values used in pattern. The sensor ( KV metre ) measures the mean, effectual and maximal extremum tubing electromotive force, power stage, exposure and exposure clip. This system determines the tubing electromotive force with truth of à ± 2 % ( Victoreen, 1995 ) . The internal ionisation chamber that measures exposure has volume of 36 cm3. The exposure clip is measured to an truth of à ± 2 % . The FAE ( Mister ) measured is converted into end product in mGy ( ma ) -1 by multiplying by a factor 0.00877/ ma ( Chang Jong and Hui- Yu, 1999 ) where ma in the denominator is the merchandise of the tubing current and exposure clip set at the clip of measuring of the end product.( 2.2 ) Environmental Monitoring and General ObservationsThe guiding rule used in all regulative paperss is that, radiation doses to the populace and to the people who work with radiation must be kept every bit low as moderately accomplishable ( ALARA rule ) . In kernel, radiation workers and the patient should be monitored at all times when working. The ground for this monitoring is to guarantee that the pattern being followed by the workers in their day-to-day modus operandi are safe and do non ensue in high doses being received. In the present survey, the dose rate at different points of involvement ( the console, entryway door behind the wall, patient waiting seats ) was measured with radiation sensor ( radiation proctor 4 minirad 1000+ ) . This device measures radiation dosage rate in ?Sv/ hour.( 2.3 ) Optical and Radiation Field Congruence/ Beam AlignmentThe beam control system is required for modulating the size of X-ray field country. Therefore, it plays an of import function in dose delivered to the patient because it controls the sum of patient surface country exposed to radiation and image contrast ( due to scattered radiation ) . The parametric quantities taken into consideration in beam control system includ e ; beam alliance, optical radiation field congruity, truth of the x Y graduated tables and illuminator bulb brightness. In this survey optical radiation field and beam alliance were examined.( 2.4 ) Ocular reviewsOne of the three parts of a quality control programme for a radiographic installation is ocular review. This portion includes look intoing the chief constituents of the equipment for proper operation, safety and good mechanical status. It is expected that they should include ; protective lead dress, lead shield of the cell wall, overhead tubing Crane, radiographic tabular array, control panel and other installations such as door and automatic visible radiation.( 3 ) RESULTS AND DISCUSSIONFive X-ray units in four infirmaries were investigated in the survey. Both the QC and environmental appraisal of the installations were carried out. Table 1 presents the radiographic equipment information at assorted infirmaries investigated. The old ages of industry of the equipment scope from 9 to 31 old ages, while the twelvemonth of installing is between 5 and 31 old ages. The consequence of age on the end product of an X-ray machine is good documented ( Mallam et al. , 2004, Ogundare et al. 2004 ) .( 3.1 ) X ray tubing OutputThe consequence of X-ray tubing end product at a distance of 1m each from the focal point of five X-ray units are presented in Table 2. The values of end product obtained in GHL ( M2 ) are comparatively low, those measured in GHL ( M1 ) are higher than those found in M2. It ranged from 0.0318 to 0.1192 mGy ( ma ) -1. However, higher end products are found at the same electromotive force in PSH and NOH. As an illustration, at 80kVp the end products are 0.0796, 0.1676, 0.2156 and 0.0762 mGy ( ma ) -1 for GHL ( M1 ) , PSH, NOH and NARH severally. The fluctuation in the end product could be attributed to the wave form, anode stuff, filtration, and tube age and anode surface harm. Knowledge of the end product value for a given X-ray tubing permit s the finding of both patient and movie exposures. It is besides used in the computation of Entrance Surface Dose ( ESD ) delivered to the patient at the point where the X-ray beam enters the patient. This dosimetry parametric quantity ( ESD ) gives the perspective appraisal of absorbed dosage to the patient. Although the entryway surface dosage is a hapless hazard index, it can be used to gauge the effectual dosage ( ED ) which better quantifies patient hazard ( Gkanatsios and Huda,1997 ) . The fluctuation in the end product among the infirmaries could take to fluctuation in doses delivered to the patients during the scrutinies. The consistence of X-ray tubing end product with ma was measured for a scope of ma for the five X-ray units at different electromotive forces. The consequences are presented in figures 1-3. Furthermore, consequences of end product measured at different kVp above 80 kVp ( GHL and NARH ) show strong correlativity with ma, nevertheless, the end products measured at lower electromotive force of 60 and 75 kVp indicate weak correlativity with ma. The X-ray tubing and the anode current are extremely stabilized at this point ( Suliman and Elshiekh, 2008 ) . The consequences of the tubing electromotive force truth for five X-ray units investigated are presented in tabular arraies 3a-3d. The tabular arraies show the tubing electromotive force set, the tubing electromotive force measured and the magnitude of divergence. It should be noted that the magnitude of divergence in kVp vary from infirmary to infirmary. In GHL, the divergence ranged between 0.9 and10.9 % for the two machines ( M1 and M2 ) . The scopes of magnitude of divergence for the three other infirmaries are ; 0.2 to 0.5 % , 45.5 to 72.7 % ( highest in this survey ) and 22.9 to 23.3 % in PSH, NOH and NARH severally. Both m1 ( GHL ) and PSH comply with the demand of à ± 5 % , while M2 ( GHL ) , NOH and NARH exceeded the demand. The grounds for higher divergence in kVp found in NOH and NARH are multifactorial. The European Commission recommended a high technique of 125 kilovolts IAEA ( 1995 ) which likely consequences in low doses, but the radiotherapists prefer the higher contrast thorax radiogram which consequences from low kVp. Earlier study indicated that increasing the tubing potency ( kVp ) from 8-13 kilovolt in lumbar and pectoral spinal column scrutiny resulted in a dose decrease of 26-36 % ( Martin et al, 1993 ) . The higher divergences outside the tolerance bound as obtained in the present survey show disagreements in kVp between the measured and the set values particularly if the tubings are non adequately maintained. Furthermore, the overly high divergence between the set and the measured kVp could cut down the image contrast ( Livingstone et al, 2004 ) . The unexpected elevated value of proficient parametric quantities which consequences from defective machine could impact both patient dosage and image quality. The tendencies found in GHL ( M2 ) , NOH and NARH require regular and repeated QC trials.( 3.2 ) Quality Control ( QC ) TrialTable 4 is the sum-up of the QC trials carried out on the equipment at different infirmaries. The kVp truth trials show conformity with acceptable bound in GHL ( M1 and M2 ) and PSH while NOH and NARH show non-compliance with acceptable bound of 5 % . As respects the kVp consistence, similar tendency is found in the infirmaries as those found in kVp truth. In footings of timer truth, it is postulated that exposure clip straight affect the entire measure of radiation emitted from an X-ray tubing. Therefore, an accurate exposure timer is critical for decently exposed radiogram and sensible patient radiation exposure. Both GHL and PSH met the the acceptable variableness bound. Since the timer truth in NOH and NARH are above the bound of acceptableness, it is expected that the radiation dosage delivered to the patient will be higher than the expected value required to bring forth the movie. Furthermore, the one-dimensionality of tubing current ( ma ) and beam alliance of both NOH and NARH fell abruptly of the acceptable bound of 10 % and 3 % severally. Regulation of X-ray tubing filament temperature ( along with the exposure clip find the quality of X raies in the X-ray beam ) is done with millampere picker in an X-ray generator. The beam limitation system is required for modulating the size of the X-ray field country. The mechanism contro ls the sum of patient anatomy exposed to radiation beam ( Papp, 2002 ) . This plays a cardinal function in patient dose and image contrast. The addition in country increases the production of the scattered radiation, hence higher patient dosage and wellness hazard. The non-compliance of optical radiation field and radiation field congruity may stem from the displacement in mechanism that moves the shutter, doing improper public presentation. This leads to higher patient dosage and repetition images ( consequence in more movies being used and more disbursals ) .( 3.3 ) Forces DistributionThe saloon chart in figure 4 shows the distribution of forces. It indicates that two classs of forces are losing ; Radiation Protection Officer/ Medical Physicist and Record Officer. The tendency is similar to the earlier work reported elsewhere ( Oluwafisoye et al. , 2009 ) . The tendency shows that radiation protection of the patients, visitants and forces is non the preoccupation of the direction of the infirmaries investigated. The absence of the record officers indicate that record maintaining at the infirmaries is far from being equal. A record maintaining system is necessary to document the quality control processs, the figure of culls and other activitie s traveling on at the X-ray units of the infirmary.( 3.4 ) Visual/ General ObservationsThe consequence of ocular observations is presented in table 5. It shows that all the basic constituents inspected were functional except LED index on the control panel found in GHL ( M2 ) . Table 6 shows the general observations carried out at assorted infirmaries investigated. Columns 1 and 2 show that the chief door taking to the X-ray room is non lead-lined. Columns 3 and 4 indicate that merely NOH has efficient 2nd door and lead-lined. The cells of the four infirmaries are efficient. This indicates that the interior decorator of the console put in topographic point equal steps that prevent the technicians from immaterial beams during exposures. The doors to the units lack automatic control, connoting that during the exposure the doors do non shut automatically as a consequence, controlled entree to the country where radiation exposure may be taking topographic point is non ensured. Lead apron was non provided in NARH. Nevertheless, the lead apron provided in GHL was non efficient. Regulation for good pattern stipulates that lead aprons and baseball mitts should be available in the radiographic room and have a lower limit of 0.5 millimeters of lead tantamount thickness ( Papp,2002 ) . It is besides apparent that technique charts were losing in all the units, an indicant that technique parametric quantities are chosen at random by the radiographers responsible for the exposure of the patient. This could take to hapless matching of patient size and technique parametric quantities. Furthermore, warning visible radiation was non provided in any of the units to warn visitants or other forces of the exposure traveling on in the X-ray room. The forces monitoring badge was merely available in NOH, bespeaking that forces dose supervising in GHL, PSH and NARH are non-existent.( 3.5 ) Dose degreeConsequence of environmental dose monitoring at the chosen locations within and in the immediate environment of each of the X-ray units investigated is presented in table 7. The consequences in all the five units indicate that the dose rate measured at the sofa are by and large really high. At the border of the cell the dosage rates recorded are greater than the background dosage rate by a factor of 7, 20, and 10 in GHL ( M1 ) , PSH and NARH, severally. The dose rate measured within the cell is comparable to the background. This status is safe for the radiographer ; nevertheless, the dose rate is high within the entryway door in GHL ( M1 ) and NARH, it is greater than the backg round dosage rate by a factor of 6 and 7.5 each. In add-on, the dose rate measured at the waiting anteroom of the patients is comparable with the background dosage rate in PSH and NARH, but higher than the background dosage rate by a factor of 10 in NOH. The high dosage rate experienced in NOH could be attributed to damaged door of the X-ray units. Another possible account for the high dosage rate at the waiting anteroom is the direct nexus between the anteroom and the X-ray machine. It is interesting to observe that there were no escapes experienced in the five X-ray units investigated as reported in the earlier survey carried out in Nigeria ( Oluwafisoye et al. , 2009 ) . Apparently, this present survey is the first QC trial and environmental monitoring attempts carried out in the five X-ray units in four infirmaries investigated. This is an indicant that the consequences are preliminary against which future measurings could be compared. Besides, the usage of thermoluminescent dosemeters ( TLD ) for the forces monitoring has ne'er been undertaken in the five units. Personnel monitoring is indispensable, since there is a nexus between the ionizing radiation and coevals of reactive O series [ ROS ] ( Cohen, 2002 ) . These ROS have been implicated in the etiology of over 100 diseases. Radiation is one of the major exogenic beginnings of free groups in adult male and it has been proved that ionising radiation produces ROS in biological system capable of destructing biomolecules such as DNA, lipoids, proteins and saccharide ( Olisekodiaka et al. , 2009 ) . Workers runing X-ray equipment are exposed to long term low doses of ionising radiation which may imp act their antioxidant position. Consequences of the QC trials and monitoring were sent to the direction of the four infirmaries investigated. In Addition, recommendations on the necessity of regular QC trial were forwarded to each infirmary for necessary actions.( 4 ) DecisionQuality control trials of five X-ray units are undertaken with intent of safety and dose optimisation in the X-rays Centres investigated. The ages of three out of five machines are good over 10 old ages. In add-on, the divergence of the measured kVp from set value on the control panel varied among the infirmaries. Two out of the five machines complied with the needed criterion of pattern, while three exceeded the demand. The QC trial carried out on kVp truth and consistence show non- conformity in two infirmaries. The distribution of forces show that, the preoccupation of the authorization of the X-ray unit investigated was the quality of the radiogram produced at the disbursal of safety of the patient. The fluctuation in the end product of th e assorted tubing is an indicant that doses among the infirmaries differ. In each of the X-ray units investigated there was no specialised installation to execute pediatric scrutinies and movie screening.

Oedipus ordered a search for everyone to help find the killer. A messenger came in (at that exact moment) to tell the king that he, in fact killed the previous king. Creon and Oedipus argued, and Jocasta added that her first son was dead. Then, another messenger came in and said that King Polybus was dead.

History Slavery and American Freedom - 1104 Words
Summary I American Slavery, American Freedom written by Edmund S. Morgan captures the history of Virginia while keeping focusing on the social and political elements that uplifted the way of slavery. With the focus on Virginia, the book also probes the central paradox of American history: how a people could have developed the dedication to human liberty and dignity exhibited by the leaders of the American Revolution and at the same time have developed and maintained a system of labor that denied human liberty and dignity every hour of the day (pg.4-5). The key to the paradox is presented in Virginia, the nations largest slave state and primary source of the ideology and leadership. Also the source of conditions which made slaveryâ⬠¦show more contentâ⬠¦It was either to keep the black woman aboard and endanger the captainââ¬â¢s crew and cargo or get rid of the woman and cease the spread of small pox.

Wanting to save the cargo and crew, Captain Dââ¬â¢Wolf came to the conclusion that there werenââ¬â¢t any alternatives and that the black woman was to be thrown overboard, whether dead or alive, into the sea. Some believe that many slave owners, traders, and anyone who participated in slave trading dehumanized slaves, although Dââ¬â¢Wolf crew men seemed to have a heart towards the black woman, thus realizing she too was human and had feelings just like him. ââ¬Å"Not everyone however, was completely convinced by Dââ¬â¢Wolfââ¬â¢s argument.

The real cost of food is not on the price tag but in the ingredients list and how it was processed. Second of all, trying to pick the best places and the healthiest food is really hard and expensive and when it is found it gets boring because of limited choices. If somebody is willing to list the names of fast food restaurants he or she would be really bored counting them but if he or she was asked to list the fast food places that have healthy food it would be a hard task. Moreover, the rate of healthy food in their menus is limited so people will have limited choices getting healthy food. Consequently people will go back to meals that has disastrous ingredients like saturated fat. For example, Maya W. Paul and Lawrence Robinson state in their article about healthy fast food ââ¬Å"A single meal of a Double Whopper with cheese, a medium order of fries, and an apple pie from Burger King contains more saturated fat than the American Heart Association recommends we consume in two days.â⬠This is actually a calamity forShow MoreRelatedChildhood Obesity: A Growing Problem795 Words à |à 3 PagesChildhood obesity is a growing problem that needs to be resolved.

Our Sense of Self Free Essays
As Feenstra (2011) states in your textbook: ââ¬Å"Social psychologists are interested in who we are. Our sense of self is affected by what we know about the self and by the people around us. The self is a powerful force. We will write a custom essay sample on Our Sense of Self or any similar topic only for you Order Now The self affects how we feel, what we think we can do, and what we in fact do. â⬠(pg. 32). Expanding on the quotation above, describe how individuals develop a self-concept and self-schema. Discuss the cultural, social, and environmental influences on that development. In what ways does our sense of self determine how we think about others and how we interact with individuals and groups of people? What is the significance of the acting self? In your response, be sure to address at least three of the key concepts presented in Table 2. 2 of the reading. Individuals develop a self-concept through learned behaviors, attitudes and beliefs that they usually get from their friends and family. Self-concept is continuously developed by the reinforcement of factors such as religion, experiences, relationships and even actions. The self-schema helps organize all the information we contain within the self-concept. The way we see ourselves versus the worldââ¬â¢s view definitely plays a significant role in the choices we make, our behavior, and even our beliefs. A personââ¬â¢s opinions of the world are generally influenced by the experiences they have with the outside world, both negative and positive, but ultimately it is the personââ¬â¢s reaction to the situation that forms the self-concept. One large impact on the development of our self-concepts is our culture. Cultures vary greatly in a variety of ways, but one large difference is in the way cultures view the self and connections with others. â⬠(Feenstra, J. , Chp. 2, Sec. 2. 1)à Cultures that are independent view people as unique individuals while interdependent cultures believe that people should be viewed as a group. Having a healthy sense of self is essential for interaction with people. Self-esteem plays a large part in determining a personââ¬â¢s personality: high self-esteem = outgoing, makes friends, ââ¬Å"party starterâ⬠, low self-esteem = quiet, keeps to oneself, doesnââ¬â¢t appear friendly. That doesnââ¬â¢t mean high self-esteem individuals are awesome, however that doesnââ¬â¢t stop them from believing they are. A personââ¬â¢s sense of self is important when it comes to interacting with people because it affects a personââ¬â¢s feelings of acceptance and rejection. If a person feels rejected by the social world then they will have a hard time mingling with others. The acting self allows us to become who we need to be at that particular moment. For example, during a job interview when asked how well you could perform the job, a person must describe their worth as high in self efficacy for that specific job. The images we portray of ourselves to others is constantly changing and therefore allows us to take on new roles when necessary. Reference: Feenstra, J. (2011). Introduction to social psychology.

Face of Bravery (Revised) free essay sample
ââ¬Å"My parents are freaking outâ⬠¦ but Iââ¬â¢m fine.â⬠These are the words of my best friend just after being told she had a brain tumor. The tumor began growing off of the Schwann cells of her facial and hearing nerve, inside of the innermost ear and brain. The tumor was slowly growing into her brain stem. According to her, the tumor was benign but the doctor warned of malignancy. Upon hearing the news I was utterly shocked, terrified, and fascinated by the science of it all at once. My best friend, my partner in crime did not, could not have a tumor. I knew immediately I needed to be calm and collected for her sake (and mine). At first I was dumbfounded at her apparent indifference towards the whole situation. She made fun of her newly deaf left ear and shrugged off any sort of condolence. It was not until later that she told me of countless nights spent crying herself to sleep, hating her new post surgical, half-paralyzed face, resenting her pain and terrified that it would never go away. We will write a custom essay sample on Face of Bravery (Revised) or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I, too, found myself awake at night asking why bad things happen to great peopleâ⬠¦ I never did resolve that question. One Spring day, half a year after her multiple procedures and recovery, Kathryn told me that I would always be her best friend and thanked me for being with her from the beginning. I left my childhood behind that day. Before the diagnosis, I found myself constantly traveling lifeââ¬â¢s straightest paths I was afraid of taking chances and deviating from the norm. I was unknowingly drowning in routine, a child taking my greatest gifts for granted. I was blind to the fact that I was (and still am) blessed. I complained about trivial things, isolated myself in my room each night, slaving away over math problems and writing prompts. I rarely enjoyed the company of my family. In fact, it seemed the only communication I had with them was about schoolwork. This changed in a way that I could never have imagined. After that fateful October day, I saw everything in a different light. I found myself sacrificing precious time to talk to and check up on Kathryn. I would visit her as much as I could and direct all of my energy towards making her laugh. Gradually, I began to see the value of family again. After all, no one is guaranteed escape from tragedy. Slowly my life began to shape into something that w as fulfilling, rather than simply successful. Soon enough, I was not merely going through the motions, I was participating in real life. Kathryn taught me to live each day and appreciate it. Now I feel as if I should be thanking Kathryn. It was Kathryn who came to mind when I joined a Special Olympics swim team to teach and assist the special needs participants. In the end I learned humanity, teamwork, and the powerful bonds that can form between people who are striving towards the same goal. When I founded my reading group ââ¬Å"Teens to Totsâ⬠, I pictured the light of bright futures gleaming in the childrenââ¬â¢s eyes. I saw just that because my focus was no longer on me alone. There is nothing more fulfilling than fostering the growth of lifetime readers and ultimately, learners. I am no longer afraid to take chances, to walk upon a stage for the first time in my life and perform in front of hundreds of people (dressed as Willy Wonka himself), to surround myself with those people I care for the most, all the while becoming an individual who knows what he wants and will strive in all of his academic and extracurricular endeavors to achieve his dreams. Indeed, it is Kathrynââ¬â¢s circumstances that changed me. But it is me that confidently walks into the warm and bright light of adulthood.

Puma free essay sample
I agree that childhood is the happiest times of ones life. Children can spend their time mostly on having fun, not caring about what the others thinks about them, being really carefree. Children do not really care about how they look or what they are doing, they just do whats fun for them. Young children do not have to worry about their tests, studying all the time to achieve good grades. Children usually get what they want just by asking, because the adults just sometimes give in. thers may beg to differ but i feel that childhood is the happiest times of ones life. I think that childhood is the happiest time of ones life because children at that age do not really have a particular responsibility to hold.

In a nutshell, i considered the childhood time as the most memorable and happiest moment of life because at that age, their expectations from life and other people are just plain simple and would not cause any trouble to others.
