The purpose of this study was to identify the contents that students want to learn the most on Home-Economics. Participants were 710 middle school students(359 boys and 351 girls) from 9 schools located in 4 cities and 5 counties in CholaBukDo. The results are as follows: 1. Of 32 contents on Family life, boys were interested in 'the puberty', 'pregnancy and the ethics on sex', 'social needs', 'the importance of family relationship', and 'adolescents' physical development'. On the other hand, girls were more intered in 'pregnancy' and 'the ethics on sex', 'the puberty', 'development of career consciousness' and 'career preparation', 'the adolescents' physiolosical and physical development', and 'the importance of family relationship'. 2. Of 37 contents of Managing home resource and Consumer life subarea, boys showed their interests on 'environmental problems', 'environmental conservation', 'environmental pollution', 'management of time and work', 'knowledge', 'management of their abilities'. And girls were more interested in 'environmental conservation', 'environmental pollution', 'environmental problems', 'adolescents life', and 'management of time and work'. 3. Of 49 contents on Dietary life, boys were more interested in 'puberty and the development', 'importance of nutriment', 'nutrition and health' and 'smoking and the health'. However, girls were more interested in 'smoking and health', 'puberty and the development', 'the importance of nutriment', 'nutrition and health', 'a realistic plan to reduce the food-based environmental pollution'. 4. Of 40 contents on Clothing life subarea, while boys were interested in 'the suitable cloths on oneself', 'clothing design', 'regulation of temparature', physical protection' 'merchandising for ready-made clothing'. On the other hand, girls were mostly interested in 'the suitable cloths on oneself', and next 'the clothing design', 'merchandising for ready-made clothes','physical protection', and 'the appropriate posture and physical adornment'. 5. Of 18 contents on Residence life subarea, teachers emphasized the importance of ventilation for adjusting the room environment and students were more interested in the effective use of the residing space. In general, those middle school students in Cheolabukdo showed the biggest interest on 'Clothing life', 'Residence life' the second, 'Eating life' the third, 'Human development and Family relationship' the fourth, and Management of family resource and Consuming life' was their fifth interest. Such result was consistent with Ⅱ-Rok Park's previous research(1997). Since the participants for this study were sampled form 9 schools located in CheolaBukDo, it is not suitable to apply the results nationwide. The restricted sampling must be considered and further studies are needed to make comparisons among areas.

The study targeted Japanese employees who have visited hospital for spinal disorder. The study analyzed work environment and pain relief methods of work-related back pain patients, and the relationship between back pain and other body parts. The purpose of this study was to provide draw up measures for patients with back pain and to provide basic data for the sustainable prevention program. The study result of back pain, in other words, employees suffering from lumbago, had disparity between occupations; the highest number of patients were made up of 16-years or above long-serving employees, and below 5-years of short-serving employees. There were more patients complaining of chronic lumbago than acute lumbago, and patients recognized poor posture as the primary cause of lumbago. Furthermore, 99.5% of spinal disorder patients complain back pain, 23.2% use only alternative therapy, and 15.2% visit clinic and hospital with alternative therapy. Patients showed pain reduction and high satisfaction after using alternative therapy. The study targeted Japanese employees where complement therapy is more generalized than that of Korea, and thus there should be multilateral management programs provided in Korea as well.

What is attempted here is to find out an optimum method for the design of physical environments that could save human energy expenditures and safely perform household duties. There are, if any, very little amount of research done in this area. This is particulary so when the work relates to the designing of household storage facilities in the light of the energy metabolism of human body. The first step to this study, therefore, is to find out the ways by which we can determine the energy metabolism of human body accurately. To measure the volume and the concentration of human respiration continuously and automatically, a new apparatus is selected here. This includes the recording system with the Wright Respirometer and the Expired Gas Analyzer as well as the computer system to multiply volume by concentration of human respiration and to integrate them for a given time. Then, the author experimented on the reliability of this apparatus and came to the conclusion that this apparatus satisfied our need to research the energy metabolism of human body. Next, the general plan and procedures to experiment with this apparatus have been determined as follows: 1) subjects are three young and sound females. Their physical characteristics are shown in Table 1 and most approximates the standard characteristics of Japanese females, 2) height of open shelves is selected in such away as to correspond to the respective height of each subject(see Table 2), 3) utensils to be stored are box shaped object, which weight is 0.5kg, 1.0kg, 2.0kg or 3.0kg, 4) working motions are given while one or two hands as to place utensil on each shelf from the standard working board, 85 cm in height and then to place back it on the board from the shelf and repeated in constant velocity as 10 times per a minute, 5) each posture of motion is chosen by each subject in free, 6) procedures of measurement of human energy metabolism ard shown at(6), 1, Section 3 as specific methods for using this apparatus. Findings of this study are as follows: 1. Human energy expenditures for storing utensils on shelves by each subject are shown in quantity more accurately than in any other studies, under varying conditions about height of shelves, load of utensils and working motion with one hand and two hands (see Fig. 8~13 and Table 3). 2. Experimental formulae of human energy expenditure for that work are shown as formula (8), (9) and (10), to generalize results of 1. and to apply those for working motion under given conditions. 3. As results of analysis on gained data, we are able to show the standard model of human energy expenditures for storing untensils on shelves by the standard Japanese female (see Table 7 and Fig. 14).

Objective: The purpose of this research was to assess the agreement between job physical risk factor analysis by ergonomists using ergonomic methods and physical examinations made by occupational physicians on the presence of musculoskeletal disorders of the upper extremities. Background: Ergonomics is the systematic application of principles concerned with the design of devices and working conditions for enhancing human capabilities and optimizing working and living conditions. Proper ergonomic design is necessary to prevent injuries and physical and emotional stress. The major types of ergonomic injuries and incidents are cumulative trauma disorders (CTDs), acute strains, sprains, and system failures. Minimization of use of excessive force and awkward postures can help to prevent such injuries Method: Initial data were collected as part of a larger study by the University of Utah Ergonomics and Safety program field data collection teams and medical data collection teams from the Rocky Mountain Center for Occupational and Environmental Health (RMCOEH). Subjects included 173 male and female workers, 83 at Beehive Clothing (a clothing plant), 74 at Autoliv (a plant making air bags for vehicles), and 16 at Deseret Meat (a meat-processing plant). Posture and effort levels were analyzed using a software program developed at the University of Utah (Utah Ergonomic Analysis Tool). The Ergonomic Epicondylitis Model (EEM) was developed to assess the risk of epicondylitis from observable job physical factors. The model considers five job risk factors: (1) intensity of exertion, (2) forearm rotation, (3) wrist posture, (4) elbow compression, and (5) speed of work. Qualitative ratings of these physical factors were determined during video analysis. Personal variables were also investigated to study their relationship with epicondylitis. Logistic regression models were used to determine the association between risk factors and symptoms of epicondyle pain. Results: Results of this study indicate that gender, smoking status, and BMI do have an effect on the risk of epicondylitis but there is not a statistically significant relationship between EEM and epicondylitis. Conclusion: This research studied the relationship between an Ergonomic Epicondylitis Model (EEM) and the occurrence of epicondylitis. The model was not predictive for epicondylitis. However, it is clear that epicondylitis was associated with some individual risk factors such as smoking status, gender, and BMI. Based on the results, future research may discover risk factors that seem to increase the risk of epicondylitis. Application: Although this research used a combination of questionnaire, ergonomic job analysis, and medical job analysis to specifically verify risk factors related to epicondylitis, there are limitations. This research did not have a very large sample size because only 173 subjects were available for this study. Also, it was conducted in only 3 facilities, a plant making air bags for vehicles, a meat-processing plant, and a clothing plant in Utah. If working conditions in other kinds of facilities are considered, results may improve. Therefore, future research should perform analysis with additional subjects in different kinds of facilities. Repetition and duration of a task were not considered as risk factors in this research. These two factors could be associated with epicondylitis so it could be important to include these factors in future research. Psychosocial data and workplace conditions (e.g., low temperature) were also noted during data collection, and could be used to further study the prevalence of epicondylitis. Univariate analysis methods could be used for each variable of EEM. This research was performed using multivariate analysis. Therefore, it was difficult to recognize the different effect of each variable. Basically, the difference between univariate and multivariate analysis is that univariate analysis deals with one predictor variable at a time, whereas multivariate analysis deals with multiple predictor variables combined in a predetermined manner. The univariate analysis could show how each variable is associated with epicondyle pain. This may allow more appropriate weighting factors to be determined and therefore improve the performance of the EEM.

작업관련 근골격계 질환은 중요한 직업병 중 하나이며, 이는 치과의료 직종도 예외일수는 없다. 치과위생사는 주로 장시간 서서 진료를 하거나 머리와 목을 구부리고 어깨와 손을 많이 틀면서 움직이거나 부적절한 자세로 진료하는 경우가 많기 때문에 더욱 더 근골격계 질환에 대한 위험에 대한 노출도 크다. 따라서 본 연구는 작업과 관련하여 근골격계의 부위별 통증의 유무와 업무분야별 통증의 차이가 있는지를 알아보기 위하여 수도권 지역의 치과위생사 300명을 대상으로 설문조사를 하였고 이 중 268명이 설문에 응하였다. 본 연구의 결과는 다음과 같이 요약될 수 있다. 1. 연구대상자들의 신체부위별 근골격계 통증 정도를 분석해 본 결과, 어깨 90.3%, 목 89.2%, 다리 83.6%, 허리 81.7%, 손/손목/손가락 75.7%, 팔/팔꿈치 52.8%로 나타났다. 2. 연구대상자들의 업무영역에 따라서 근골격계 질환이 다르게 나타났으며 연구결과, 외과업무의 경우 목, 허리, 다리, 어깨, 손, 팔로 나타났으며 보철업무의 경우 어깨, 다리, 손, 목, 허리, 팔로 나타났다. 교정업무의 경우 목, 어깨, 손, 허리, 다리, 팔로 나타났고 접수의 경우 목, 어깨, 허리, 다리, 손, 팔로 나타났다. 모든 치료의 경우 어깨, 허리, 목, 다리, 손, 팔로 나타났다. 여기서 나타난 것처럼 연구대상자들이 주로 하는 진료에 대한 근골격계 통증이 신체부위별로 다르다는 연구결과가 나왔다. 3. 근골격계 질환의 주요변인에 대한 연구결과, 일반적 특성은 통계적으로 유의하지는 않았지만 신장이 큰 연구대상자들에게 허리와 어깨의 통증이 많았고 체중이 적게 나가는 연구대상자들은 목과 팔의 통증이 높았다. 연령은 29~33세는 어깨, 34세 이상에서는 팔/팔꿈치가 높았으며 이는 통계적으로 유의하였다(p<0.05). 근무환경은 경력이 높아질수록 손/손목/손가락은 통증이 증가하였고(p<0.05) 목과 어깨(p<0.05), 팔(p<0.01), 허리는 3~4년의 경력에서 가장 높았다. 그리고 다리/발은 1~2년의 경력에서 통증경험이 높았다. 근무시간은 시간이 증가함에 따라 목에 대한 통증이 높아진다고 하였으나 유의한 차이는 없었다. 그러나 손/손목/손가락에서는 근무시간이 적을 때 높은 통증경험을 나타냈으며 통계적으로 더욱 유의한 차이를 보였다(p<0.01). 근무처에 따라서 분과병원에서는 손/손목/손가락에서 높은 통증경험율을 나타냈고(p<0.05) 중소치과에서는 다리/발에서 높은 통증경험률을 나타냈다(p<0.05). 이와 같은 결과는 치과위생사의 근골격계 질환은 평균이상으로 많으며 이 질환에 대한 위험성을 인식하고 경각심을 느껴야 한다고 보여진다. 근골격계 질환은 초기에 발생되면 간단하게 치료받을 수 있지만 누적되어서 오랫동안 방치되었을 때는 이미 정상으로 되돌릴 수 없기 때문에 올바른 자세를 유지하고 통증이 나타나거나 피로가 쌓일 경우 즉시 치료를 하고 적극적인 자세로 응대하고 지속적인 노력이 필요하다고 보여진다.

The purpose of this study is to analyze the phases of back pain occurring on pregnant women, and to raise the necessity of the pain management on the basis of the former analysis. The objective group is 284 pregnant women who visited department of OBGY of hospital located both in Seoul and Andong. The results are as follows; 1. 204(71.8%) pregnant women were suffering from back pain. The ratio of pain occurrance in terms of the duration of pregnancy shows that 78.3% within 3 pregnant months, 68.4% between four and six months and 72.1% over seven month. Most common ares of pain was low back area rating 60.5%. 2. The most painful postural for the suffering women was lying on the back rating 35.9% and the next painful posture was standing rating 34.4%. And the most painful movement was to maintaining continues movement(57.8%). Twisting back rates the second(17.2%). These two variables were relevant each other(p<0.05). 3. 46.7% of pregnant women were experiencing nocturnal pain. Among women experienced the pain before pregnancy, 39.9% were suffering during the pregnancy. The occurrence of nocturnal pain was related to the pain before and after the pregnancy(p<0.05). 4. 58.8% of pregnant women who experience back pain take the pain for granted as a normal proceeding of pregnancy while 3.9% recognize the symptom as an abnormal. Pain recognition in accordance with the phases does not show much difference(p<0.05). 5. It is shown that the more one delivers the number of babies, the faster back pain occurs(p<0.01). 6. 32.3% of the pain-suffering women have family member(s) having back pain. Family member(s) of the women who does not experience the pain don't have the pain either. This case reports 46.1%. Statistically, these two variables are relevant(p<0.01). 7. 43.0% of back pain experiencing women does not have any particular management plan against the pain. 20.7% is exercising as for prevention. Women who recognize the necessity of some means of therapy for their pain marked 42.9%. The majority(65.8%) of women responded exercise gymnastic work-out are most appropriate pain management. The above results show that a great number of pregnant women is experiencing back pain, however, they properly managed. This span suggests that appropriate advocacy and education for pregnant women is necessary. It is recommended that positive contribution can be made to better health of pregnant women when pain management by physical therapist is given.

MRI는 1970년을 시작으로 자장 세기와 수신 채널 수, 촬영시간의 단축 등으로 많은 발전을 해 오고 있으며, 병원 또한 각종 전산 시스템과 무선 네트워크의 발전으로 인해 각종 진료 영상장비로부터 디지털 영상을 획득, 저장 및 관리하게 되었다. 하지만, 국내 대학들은 고가의 실습장비와 유지비로 인하여 자체에서는 실습을 하지 못하고 있으며 임상 실습에 의존하고 있다. 이에 윈도우즈 운영체제의 PC상에서 MR 환자의 검사 프로그램을 개발하여 학생들이 많이 다루어 봄으로써 임상에서 근무하기 전 많은 도움을 주고자 하였다. MRI Simulator의 Relational Database 설계는 각 기능과 자료의 특성에 따라 7개의 Table로 구성하였으며, 환자정보 설계는 임상에서의 환자등록 방법을 기준으로 각 단계별 기능을 분류 하였다. 또, 검사를 위한 기본 정보 설정을 가정하여 각각의 설정 값 및 그 내용을 분류 하였다. 실행 단계별 메뉴는 한 눈에 볼 수 있도록 왼편에 배열을 하였다. 환자 등록은 이름, 성별, 고유번호, 생년월일, 몸무게 등 기초정보를 입력하고, 환자의 자세와 검사 방향을 설정하였다. 또, 검사부위와 Pulse Sequence을 나열하고, 선택하도록 분류하였다. 그리고 Protocol 이름과 부가 인자들를 입력할 수 있도록 하였다. 최종 화면은 검사 영상과 환자 정보, 검사 조건 등을 확인할 수 있도록 설계하였다. 이 프로그램을 통해 환자정보의 입력과 검사조건의 변경을 학습해봄으로써 이론과 실습을 통한 용어의 이해에 많은 도움을 주어 실제 임상근무에서 배우는 시간을 단축시킬 수 있다.

A long life is the desire of many people. The purpose of this study was to describe long life factors for people aged one hundred and above on Chju island. The research was conducted using a phenomenological method to add understanding to this subject. The field work for this study was done from July, 1997 to February, 1998 on Cheju island. The sample consisted of 10 persons of one hundred or above and 12 families. They were audio-recorded and analyzed using Colaizzi's (1978) method. The results of the present study shows the following: The thoughts of the persons one hundred and above showed ten important concepts; 'dietary regimen', 'mental regimen', 'sleep regimen', 'residence regimen', 'health regimen', 'labor regimen', 'exercise regimen', 'being born', 'filial piety and posterity', 'attachment to life'. Concerning 'Dietary Regimen': Dietary regulation, Preferential food intake, Living on vegetables, Light eating, and concern for longevity in food intake were important. Concerning 'Mental Regimen' : Harmony, Clearheadedness, Mildness, Abstinence, Generosity, Relaxation, Gaiety, Inspiration and Strength were important. Concerning 'Sleep Regimen'; Enough sleeping hours, Sound sleep, Curved sleeping posture, and Comfortable bedding were important. Concerning 'Residence Regimen' ; Clean dwelling, Pleasant surroundings, Thatched house life, Living in the village with good-hearted people, and Regular life were important. Concerning 'Health Regimen'; Temperance of drug, use Proper temperature, Proper humidity, and a Clean body were important. Concerning 'Labor Regimen'; Agricultural labor, Diligence, and Domestic labor were important. Concerning Exercise Regimen': Proper exercise, and Sunbathing were important. Concerning 'Being Born' ; Strong physical constitution, Longevity lineage, and Destiny were important. Concerning 'Filial Piety and Posterity' : Showing respect to a long-lived elder and Reducing anxiety were important. Concerning 'Attachment to Life' ; The desire to live long was important. The following conclusion was made from the above results. Human beings cannot avoid death, but the span of life can be prolonged to the maximum span of human life by wisdom, health care, and proper environmental conditions. As a result, a health regimen must be imposed for longevity such as controling food intake, having positive thoughts, being relaxed, sleeping enough, clean dwelling, taking care of oneself which can improve immunity and resistance to decrease, as well as proper labor and exercise. In addition, when filial piety is served, the desire of longevity and retaining one's youthfulness for a long time can be achieved. These should be done to live long and lead a qualitative life. By the results of this research, the following is suggesed for nursing. To satisfy the basic nursing principle that nursing must be practiced to help people live long, education must be spread to people who are nursed and their family so that they can lead a healthy life. And in nursing elders, nurses must recognize that elders have a strong desire for life, even though they may have negative thoughts about life at times. Therefore nurses have to respect the elders' value of life, and help them improve their self-esteem and self -fulfilment.
