The purpose of this study was to evaluate the Quantity and Quality of food and nutrient intake of preschool children. The subjects were 57 children aged 3 to 6 years in Gumi day-care centers. Total daily dietary intakes were calculated by weighing food consumed at the day-care centers taken together with dietary records by children's mothers for intakes at home. This survey was conducted during 3 days including week and weekend days. Diet Quality was assessed by NAR (Nutrient Adequacy Ratio), MAR (Mean Adequacy Ratio), food group pattern and DDS (Dietary Diversity Score). The daily food intake was 992.7g, the plant food intake $(68\%)$ was higher than animal food intake $(32\%)$. The daily energy intake was 1249.2 kcal $(85\%\;RDA)$ and protein 43.8g $(153.6\%\;RDA)$. Percentage of calcium, iron, and niacin consumed below $75\%$ of RDAs were $29.8\%,\;35.1\%\;and\;28.1\%$, respectively. Proportions of energy from carbohydrate, protein and fat were $61.0\%,\;14.1\%\;and\;25.5\%$, respectively. Calorie intake proportion of breakfast, lunch, dinner and snack were $15\%,\;20\%,\;19\%\;and\;46\%$, respectively. The NAR of Ca and Fe and MAR were 0.84, 0.85 and 0.92, respectively. Thirty-one point six percent of children consumed 5 food groups (GMFVDS=110111) per day. Persons who had higher DDSs correlated positively with NAR and MAR. As a result, dietary intake of preschool children partially showed a problem of over and under nutrition in Quantity or Quality. We hope that the result of this study could be helpful for developing the nutrition education program for the health and nutrition of preschool children.

This study was performed to assess the physical activity, food habit and nutrient intakes by gender and age groups in 193 adults aged 20-59 years (84 men and 109 women) in Pusan. Data for physical activity and dietary survey was assessed by a questionnaire and 24hr recall method. The mean BMIs of men and women were 24.0 and 22.2 respectively and BMI of women in the 20-29 years group (20.9) was significantly lower than that of women in the 30-49 and 50-59 years group (22.7, 23.2) (p < 0.01). 56.0% for men and 44.0% for women exercised regularly. The mean exercise duration per once of men (69.7 minutes) was significantly higher than that of women (52.4minutes) (p < 0.01). The mean exercise duration per day was 36.0 minutes for men and 29.9 minutes for women. 67.9% for men and 78.0% for women often skipped meals and 68.4% for men and 69.4% for women skipped breakfast in the main. The mean energy intake of men was 2067.2 kcal and that of women was 1783.1 kcal comprised of 87.2% and 92.1% of the Estimated Energy Requirements (EER). The mineral intakes of men and women were over Recommended Intake (RI) and Adequate Intake (AI) except calcium and potassium. The mean calcium intake was 88.3% for men and 84.0% for women of RI. The mean potassium intake was 63.3% for men and 59.2% for women of AI. The mean vitamin intakes of men and women were over RI and AI except vitamin C and folic acid. The mean vitamin C intake was 92.5% for men and 85.6% for women of RI. The mean folic acid intake was 76.6% for men and 70.0% for women of RI. The mean energy, protein, sodium and zinc intakes of men were significantly higher than those of women (p < 0.01, p < 0.05, p < 0.05, p < 0.05). The mean vitamin $B_6$, vitamin C and folic acid intakes of men in the 20-29 years group were significantly lower than those of men in the 30-49 and 50-59 years group (p < 0.01, p < 0.05, p < 0.05). For energy, proportions of subjects with intake levels less than 90% EER were 64.3% for men and 56.0% for women. For calcium, proportions of subjects with intake levels less than Estimated Average Requirement (EAR) were 52.4% for men and 59.6% for women. For folic acid, proportions of subjects with intake levels less than EAR were 78.6% for men and 83.5% for women. For iron and phosphorus, proportions of women (36.7%, 14.7%)with intake levels less than EAR were significantly higher than those of men (6.0%, 1.2%) (p < 0.01, p < 0.001). For men, age was positively correlated with intakes of potassium, vitamin $B_6$, vitamin C and folic acid (p < 0.05, p < 0.05, p < 0.05, p < 0.01). For men, weight showed significantly negative correlations with intakes of carbohydrate, phosphorus, potassium, zinc, vitamin $B_6$ and folic acid (p < 0.01, p < 0.05, p < 0.05, p < 0.05, p < 0.01) and BMI showed significantly negative correlations with protein, lipid, phosphorus, potassium, zinc, vitamin E and folic acid (p < 0.05, p < 0.05, p < 0.05, p < 0.05, p < 0.05, p < 0.05, p < 0.05) For men, exercise duration per once showed significantly positive correlations with intakes of calcium, phosphorus, potassium, zinc, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C and folic acid (p < 0.01, p < 0.05, p < 0.01, p < 0.05, p < 0.05, p < 0.01, p < 0.01, p < 0.01, p < 0.05). Therefore, nutritional education for adult health management is needed by gender and age groups.

This study was conducted to compare the characteristics of high performane areas for family planning with that of low performance areas and to find factors which strongly affected contraceptive practice behavior. For the study, eight areas were selected from 274 rural family planning canvassing areas of Korean Population Policy and Program Evaluation Study, which was an action study operated in all areas of Cheju Island from July 1, 1976 until December 31,1979. As a first step of the action study, Cheju Island was devided up 318 family planning canvasser areas Each area was consisted of 200 households in rural district and 300 households in urhan one Duriog the period of project, each canvassing area had been managed by a female family planning canvasser, selected by director of health center considering several individual conditions needed for family planning activities Basic activities of canvassers were to counsell all the eligihie couples in own charged area about family planning methods and also to distribute contraceptives such as condoms and oral pills. In case couples desire to accept sterilization including vasectomy and tubal-ligation, the canvassers played a linking role connecting potential client with family planning field workers. Canvassng areas shows significant differentce in performance for family planning, nevertheless they are supposed to have almost the same conditions regarding family planning distribution channel. Because the purpose of the Cheju project was to eliminate all the problems that existed in governmental distribution system, that is to remove geographic, economic, cognitive and administrative barriers Accumulated performances of family planning methods accepted by residents in each area were calculated by eligible women aged 14-49. And then canvassing areas were ranked according to performance score. Consequently, 4 areas in extremely high and low family planning performance areas were selected respectively. Major results were obtained by comparing characteristics of high performance area with that of low performance areas, which are as follows: 1. The mean number of living children was about the same both in high and low performance areas for family planning. But respondents' mean age (38.5) in high performance areas was higher than that (37.0) in low performance areas 2. Respondents' perception in the expectant educational level of others' children in high performance areas was higher than that in low performance areas, although respondents educational level, monthly expenditure and ratio of children in high school and above was not different. 3. Ratio of ownerships of TV and newspaper in high performance areas was highen than that in low performance areas 4. The duration of canvasser' charge in high performance areas was longer than that of low performance areas, showing the fact that canvassers didn't move cut in high performance areas 5. In high performance areas, canvassers' houses were relatively located in the center part of the village. And so villagers resided in near distances from the anvasser's house 6. 4H clubs' activities in high performance areas were more active than those in low performance areas Therefore it was assumed that cohesiveness of community in high performance areas were stronger than that in low areas. 7. Canvassers' family planning practice rate was higher than that in low performance areas, and also canvassers' human relationship was more sociable than that of canvassers in low performance areas. 8. Fourteen variables which showed relatively high significance level in $X^2$ and F test were selected as independent variables for stepwise regression analysis. According to the results of regression analysis. five of 14 variables-distributors education level ($R^2$=.4439), duration of distributor's charge ($R^2$=.6166), 4H club activities ($R^2$=.6697), canvasser's contraceptive practice ($R^2$=.7377) and location of distributions house ($R^2$=.8010) explained 80.1 percent of total variance.

The purpose of this study was to investigate whether 12-weeks of movement training would increase the psoas major cross-sectional area (CSA) in senior men and women. Fifty eight men and women aged 65 to 80 years old ($69.6{\pm}3.7$, 30 male, 28 female) were divided into a control (n=19) and exercise group (n=39). Subjects were assessed before and after the training program for stature, body mass, and magnetic resonance imaging of the psoas major and the quadriceps muscle. The experimental group performed exercises using machines designed to improve the movement of the hip at a frequency of twice every week, with a total of 23 trainings in 12-weeks. Magnetic resonance images of both thighs and the abdomen and psoas major were obtained, aimed at 50% of the length of the greater trochanter and the lower edge of the femur and between the fourth (L4) and fifth (L5) lumbars. A 9.4% increase in the psoas major CSA in the training group was observed. In the male and female breakdown, a 11.5% and 8.4% change was observed in males and females, respectively. In the quadriceps, there was no significant statistical improvement in either males or females. Furthermore, in the control group, there was no significant change seen in either the psoas major or the quadriceps. As a result of conducting training that enables upkeep of posture and smooth linkage of the lumbar spine, the pelvis and thighbone, the psoas major CSA of older adults were improved in a short period of time. For this reason, the possibility of improving the psoas CSA, which decreases remarkably with increased age, by improving the linkage of the body trunk is also suggested.

The purpose of this study was to analyze the characteristics of socio-demographic, organizational culture, organizational conflict and organizational commitment, and to examine the interrelation of influential factors in the organizational commitment. The data for this study were collected through a self-administrated survey with a structured questionnaire to 1,027 subjects from several medical doctor staff members, nursing staff members, administration staff members, pharmacist, and technical expert of eleven hospitals. The data were collected by self-reporting questionnaire from July 29 to September 7, 2002. In this analysis frequency test, t-test, ANOVA, multiple regression were used. The main results of this research is as following; 1. According to socio-demographic characteristics the respondents' level of the organizational commitment was higher in a administration staff members than others, for males than females, and for employees aged more than forty, as working for longer time, and as higher level of the working position. 2. According to the organizational culture characteristics the progressive culture, affiliative culture, and task-focused culture among many types of organizational culture were moderately and positively correlated with the level of the organizational commitment while the hierarchical culture was negatively correlated. 3. According to the organizational conflict characteristics as the respondents who got less conflict experience in the organization, their level of the organizational commitment was higher. And, technical conflict experiences were expressed greater than hierarchical conflict experiences. 4. According to the job satisfaction characteristics as his or her satisfaction that is about the promotion, working itself, salary, and fellowship in the organizational was higher, the level of the organizational commitment was higher. The most important factor of the satisfactions was the fellowship among the respondents while the level of job satisfaction for the promotion and salary was average. 5. Overall, according to the result of Multiple Regression as older age and longer working hours, the level of the organizational commitment was higher and as a higher level of the satisfaction for the promotion, working itself, salary, and fellowship in the organization, it caused more effective factors for the organizational commitment. 6. According to the result of Multiple Regression for the doctor staff members in special hospitals rather than general hospitals the hierarchical culture and task focused culture was positively correlated with the satisfaction of working itself while hierarchical conflict factors in the organizational conflict characteristics was negatively correlated with the organizational commitment. For the nursing staff members the affiliative culture and the job satisfaction for the promotion, working itself, salary, and fellowship were positively correlated with the organizational commitment. For the administration staff members as the job satisfaction for the fellowship was positively correlated with the organizational commitment. For medical and pharmacy staff members as more working experience, correlation with the organizational commitment was positive. Besides, as he or she has a high perception of the affiliative culture, it caused statistically more effective factors for the organizational commitment. For the skill and technicians, male worker expressed greater organizational commitment in the organization than female worker. And also older age along with higher education also showed higher organizational commitment. Moreover, the job satisfaction for the fellowship was positively correlated with the organizational commitment. This study identified the major effective factors of the organizational commitment and analyzed the differences among the job category. In that respect, it is significant for the study to be able to provide a reference for managing hospital of industrial accident and organizational development. However, this study has a problem, which is not to identify a valuable model for examining the relationship between organizational factors such as organizational culture, conflict, satisfaction, and commitment. Therefore, further study is needed and strengthened in the field of organizational commitment for hospital for industrial accident.

The aim of a school attendance policy (SAP) is to ensure breakfast time for school-aged adolescents. Therefore, this study investigated the effects of SAP on dietary behavior, particularly breakfast consumption, among adolescent middle school students (n=426) in the Ansan area of Gyeonggi-do. After implementation of the SAP, the response rates for eating breakfast every-day among boys (P>0.05) and girls (P<0.05) slightly increased by 44.6% and 35.8%, respectively, compared to before the SAP. Further, the degree of satisfaction with breakfast increased among both boys ('satisfied' and 'strongly satisfied'; 32.4% and 21.6%, respectively) (P<0.01) and girls ('satisfied' and 'strongly satisfied'; 32.8% and 14.2%, respectively) (P<0.001) compared to before the SAP. Moreover, boys (56.8%) and girls (53.9%) were aware that the SAP increased breakfast-eating frequency. Increases in deep sleep as a result of the SAP were high in both boys (39.2%) and girls (47.1%), and sleeping hours among boys (P<0.05) and girls (P<0.01) increased compared to before the SAP. The respondents were aware of the positive effects on physical function such as reduction of physical fatigue (boys 40.1%, girls 38.2%) and improvement of physical health (boys 36.5%, girls 32.8%). Thus, systematic and sustained political support at the national level is required to encourage healthy breakfast eating and physical activity in middle school students.

The purpose of this study is to examine effects of constraint-induced movement therapy(CIMT) and/or cognitive-perceptual training(CPT) on the change of hand function in cerebrovascular accident(CVA) patients and to evaluate the change in the amount and quality of use of the affected upper extremity in performing daily living tasks. The subjects of study were 10 patients who had been under rehabilitation for more than three months after CVA onset. They were all determined as mild cognition impairment according to NCSE or MVPT test. For CIMT group, to restrict the movement of the unaffected hand the subjects had been worn modified resting arm-splint in daytime for 4 weeks. For CIMT+CPT group, the subjects were performed CPT with CIMT and control group had been under conventional occupational therapy for the same period. CIMT+CPT group showed significant improvement in simulated feeding, lifting large light objects, and lifting large heavy objects of Jebsen-Taylor Hand Function Test. CIMT group also showed significant improvement compared with control group. The mean changes of the amount of use(AOU) of the affected arm had a statistically significant difference among groups (p<.05). While CIMT+CPT group had the biggest change in the quality of movement(QOM) of upper extremity of the affected side, CTL group showed the smallest change. Both CIMT and CIMT+CPT groups had statistically significant difference in the change in the quality of movement in upper extremity of affected side with CTL group(p<.05), but there was not significant difference between CIMT group and CIMT+CPT group. CIMT performed to the patients of stroke, with mild impairment in cognitive perceptual abilities showed the improvement in hand movement and AOU and QOM of upper extremity in the affected side and the combination of CIMT with CPT showed synergic effects.

Due to the increase of the aged population and population of the disabled today, there is a growing demand for rehabilitation medical instruments. Furthermore, there is a growing demand for evaluation indices for services that should be provided for uses of the rehabilitation medical instruments. In order to evaluate rehabilitation medical instrument designs in this study, the basic index for design evaluations shall be identified to search for assessment plans. Through this, new evaluation indices will be deduced through discussions and analysis of rehabilitation medical experts, biomedical engineers, and designers. The results of this study are summarized as follows. First, the existing design evaluation indices were collected and analyzed to construct 10 rehabilitation medical instrument design evaluation indices and 44 sub-evaluation items. These will be important evaluation standards for designing rehabilitation medical instruments in the future. Second, the design evaluation indices that must be taken into consideration when developing health care rehabilitation medical instruments are the 10 design evaluation indices of usability, cognition, safety, learning, motility, durability, economic feasibility, space, aesthetics and environmental aspects. Third, design evaluation indices of environment, space, cognition, usability, economic feasibility and aesthetics are indices that must be taken into consideration for product design, while learning, safety, motility and durability are factors that must be given special consideration for rehabilitation medical instrument design evaluation indices. Fourth, if existing product design evaluation indices placed importance on environment, space, cognition, usability, economic feasibility and aesthetics of products for design evaluation indices, rehabilitation medical instrument design evaluation indices placed importance on learning, safety, motility and durability on top of usability and economic feasibility, which are the differences between the design evaluation indices of rehabilitation medical instrument and other product designs. The 10 rehabilitation medical device design evaluation indices and 44 sub-evaluation items were carried out in this study. This research is only on the overall rehabilitation medical device design evaluation indices. In future research, the evaluation indices will be applied in the actual rehabilitation medical design device through production of prototypes, while making revisions and supplementations where necessary.

Purpose: Obesogenic environments in children, in particular excessive intake of sodium, generate hypertension, which is a major risk factor for chronic diseases. Methods: In all, 725 children, 379 boys and 373 girls, aged 8~9 years were recruited from seven elementary schools in Kuro-ku, Seoul. To evaluate whether or not obesity risk was modulated by salt-sensitive genes, Solute Carrier Familiy 12 member 3 (SLC12A3) was used as the target. After children were assigned into obese (BMI > 85 percentile) or non-obese groups, anthropometry, blood biochemistry, and dietary intakes were measured according to the genotypes GG (wild) or GA+AA (hetero+mutant). Results: Without gender differences, high TG and low HDLc were detected in the obese group compared to the non-obese group. Regardless of obesity, weight gain and blood pressure (BP) increased in the SLC12A3 GA+AA genotype rather than in the GG type. HDLc was associated with obesity risk without genotype difference. Odd ratios for risk of obesity were 15.57 (95% CI 2.192~110.654), 22.84 (95% CI 1.565~333.469), and 9.32 (95%CI 1.262~68.817) in boys and girls with GA+AA genotypes as sodium intake increased above 4,000 mg/day. Dietary calcium, sodium, folate, and vit C were associated with obesity risk according to gender or genotype differences. Since high folate intake reduced obesity risk in only boys with GG type. Risk for overweight and obesity increased in boys with GA+AA genotypes and dietary habits with high sodium and cholesterol and low folate. Conclusion: The A allele of SLC12A3 rs11643718 was sensitive to development of obesity in children as sodium intake increased.

This study was based on the data of total mineral content of about 99% at the age of 16-26 years, we aimed at female university students who are important for bone formation in their early 20s. The purpose of this study was to investigate factors of eating habits affecting their bone density and to provide data to prevent osteoporosis which might occur in the future. It was conducted on 100 female university students in their 20s, the bone mineral density according to BMI was measured by DEAX, and the analysis of 10 eating habits items and the results of BMD measurement on their own results in Excel 2010. As a result, the height was $161.08{\pm}4.70cm$, the weight was $52.43{\pm}6.43kg$, and the BMI was $20.22{\pm}2.48$, which correlated with BMD (p<0.05). According to the BMI classification, 20 had low weight and 80 had normal weight, and BMD was $0.20{\pm}0.41$ at normal weight. In the same sex, the mean T-score of the young adult group was $-0.04{\pm}0.99$ compared with the BMD of the young adult group, and the mean Z-score of the same age group was $0.02{\pm}0.93$ (p<0.001). Eating habits affecting bone mineral density were significantly affected by 3 meals per day, 1-3 cups of coffee per day and p<0.05 for Low salt formula intake. 6-9 dairy product intake was also p<0.05 but not significant. Therefore, it is considered that when 20s female students become middle-aged woman, they should have proper eating habits so that osteogenesis can be improved at young age in order to prevent bone disease.
