The purpose of this study is to evaluate the physical fitness status and health promoting life styles of the workers. For the purpose, 108 workers who attended the exercise program in Inchon branch of KISCO were selected as the subjects. From Oct. 20th to Nov. 30th, in 1998, they were firstly assessed their physical fitness. The items include cardio-respiratory endurance, flexibility, muscular strength, muscular endurance, agility, power, balance, body composition, etc. Secondly, the health promoting life styles were asked by questionnaires about daily life and dietary habits. Both of them were evaluated by 5 or 3 levels as A(very good) to E(very poor) or A (good) to C(poor). Those data were analyzed percentile, mean, standard deviation by SAS program. Major findings are as follows ; 1. The health promoting life styles were generally good, but 43.5% of the subjects didn't exercise at all. Most of them(93.5%) thought about their physical fitness status as lower than average level. About half of them(48.1%) didn't drink alcohol, non smokers were 70.4% of them. But they had poor dietary habits(lower than average level : 79.6%), females were a little bit better than males. The aged group had the poor body compositions, 21.4% of females and 10.0% of males were obese. 2. Physical fitness status of the workers were assessed as two areas, one is health related, the other is physical function related area. In the health related area, females were better than males, in view of age, forties aged group had the highest scores of all items except cardio-respiratory endurance. Among 'A' and 'B' level, muscular endurance was showed most frequently, followed by muscular strength, flexibility, cardiorespiratory endurance. In physical function related status, balance was ranked highly in the portion of over 'B', followed by power, agility. In view of sex, males were better than females for all items except balance, and there were various figures in the status by age groups. 3. Comprehensive assessment scores were poor(under 'D' leves were most frequent), females were better than males, and teenage group had the worst scores. In ages of the physical fitness, generally they had 1 year under their real ages, and females were better than males. In view of age, forties aged group was ranked highly and teenagers had lowest scores.

The goal of this study is to verify the effectiveness of collective leadership. Specifically, we examine the direct effect of collective leadership on creative behavior and how this relationship is affected indirectly by organization-based self-esteem. Further, we identify the conditional indirect effect psychological safety has in moderating this mechanism. To minimize the common method bias, job rank and the affectivity in work situations were set as control variables. After excluding ten univariate outliers from 319 responses that were collected, a total of 309 samples were used for analysis. Our findings showed that collective leadership has a positive effect on the creative behavior of organization members, and that organization-based self-esteem played the role as partial mediator in the relationship between collective leadership and creative behavior. Also, the conditional indirect effect of psychological safety was found to be significant in the 'high' and 'very high' percentile levels, but not in the 'very low,' 'low,' and 'middle' levels. Together, the findings imply that when leaders at organizations promote members' organization-based self-esteem and creative behavior through collective leadership, it can be more effective when members feel high psychological safety in the organization.

This study was done to determine the factors associated with childhood overweight in 721 sixth grade elementary school students, in Busan. The students' heights, weights, waist circumferences and triceps-skinfold thicknesses were measured using standard techniques. Other data were collected using a questionnaire that included information about physical activity, television watching, and the amount of exorcise taken during leisure times, family history of diseases related to obesity: social data including family income, parents'education and occupations, eating behaviors; parental weights and heights; and parental activity levels. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex. The prevalence of overweight revealed no significant difference between sexes, (24.2% in boys and 22.03% in girls). The risk of childhood overweight was significantly greater if either the mother or the father were overweight. The odds ratio for childhood overweight associated with maternal overweight was 5.045 (94% CI : 3.262-7.801), and 2.727 (95% CI : 1.764-4.218) was the case for parental overweight. Children having a history of hear diseases had higher odds ratios than those who did not. The odds ratios for overweight associated with income were not different. However, a higher odds ratio for overweight was observed in children whose fathers had only an elementary or middle school education than those whore fathers had a high school or college education. Children whose fathers' occupations were service workers or shopkeepers (OR : 3.314, 95% C = 1.851-5.934) or had no occupation (OR = 3.756, 95% CI : 1.898-7.430) had a treater risk of overweight than those whose fathers'were professionals or once workers. The risk of overweight increased in children having more irregular meal times and faster eating times, rather than those having an intake pattern of high energy and sugar containing floods. The amount of exercise taken during leisure times, and daily physical activity showed no difference between overweight and non-overweight children. However, television watching time, especially on weekends, was greater in overweight children than in non-overweight children. Television watching time was positively correlated with BMI, triceps-skin(31d thickness, waist circumference and waist/height ratio. Therefore, television watching was found to be a useful predictor of overweight in children. Television watching in children was negatively related to paternal activity levels, and positively related to parental television watching time. In fact, fathers whose children were overweight were physically less active than fathers whose children were non-overweight. Parents appeared to be a strong influence on their children's physical activity levels. In conclusion, a low family social class, defined on the basis of the father's occupation or education, parental overweight, increased television watching, and unhealthy physical activity levels in parents were all considered risk factors for childhood overweight. Among these, television watching time and lack of physical activity were considered to be the most important risk factors that could be easily modified for the prevention of and intervention in, overweight in children.

This study was performed to determine the dietary risk factors associated with hypertension. The hypertensive group were composed of 112 hypertensive patients (male 53, female 59) who first visited the hypertension clinic and had been diagnosed as having primary hypertension ($SBP{\ge}140mmHg\;or\;DBP{\ge}90mmHg$). The regular visitors or the subjects on special diets or medical therapies were excluded. The normal group consisted of as subjects (male 41, female 54) matched with age and socioeconomic levels. The subjects having higher intakes (above the 75 percentile) in energy, protein, iron, vitamin A or C showed significantly higher hypertension risk estimated with odds ratio after the covariance factors (age, sex and BMI) were adjusted. More than 2400 mg of sodium (6 g of salt) intake was associated with significantly higher risk of hypertension (odds ratio: 1.773, CI: 1.014-3.014 for $SBP{\ge}140mmHg$; odds ratio: 2.373, CI: 1.359-4.215 for $DBP{\ge}90mmHg$). Hypertensive group showed significantly increased intakes of vegetables and fish and shell fish compared to the normal group. When the vegetable intakes were classified into Kimchi, fresh vegetables and cooked vegetables with seasoning, the hypertensive group was observed as having higher intakes of Kimchi and cooked vegetables with seasoning. The intakes of highest quartile for vegetables (${\ge}327g/day$) (odds ratio: 3.164, CI: 1.740-5.752), fish and their products (${\ge}102g/day$) (odds ratio: 2.756, CI: 1.486-5.109), grains(${\ge}311g/day$) (odds ratio 2.393, CI: 1.186-4.832), meats and their product (${\ge}106g$) (odds ratio: 2.210, CI: 1.225 - 3.987) compared to the lower were significantly associated with the higher risk of hypertension estimated with DBP (${\ge}90mmHg$) after covariance factors were adjusted. In conclusion, our findings confirm that higher intake of energy or sodium are associated with the increased risk of hypertension. Because increased intake of vegetable or fish was associated with the higher risk of hypertension, in contrast with the finding of western countries, choosing or preparation of vegetables or fish with reduced salt is recommended.

Needle stick injury, in which blood-borne pathogens including Human Immune-Deficiency virus and hepatitis B virus are transmitted, is one of the major occupational hazards that health professionals face everyday. In order to provide basic data for the development of educational programs for health professionals aimed at preventing and effectively managing needle stick injuries, a retrospective descriptive study was carried out .The subjects of the study were 630 health professionals, 499 nurses and 131 physicians, from two university hospitals in Seoul, Korea. Data on episodes of needle stick experiences over the past is months September 1994 through August 1995, were collected between September 1 and 7, 1995. A Questionaire developed by the researcher was used. The frequencies and the percentile score for episodes of needle stick injuries were calculated using the PC-SAS program. The differences and similarities in reference to the structure, career, and specialty variables were analysed by X$^2$-tests. Results are as follows : 1. Of the sample, 521(82.7%) reported a needle stick injury, 33.4% reported 3 or more episodes of needle stick injuries. 2. The needle stick injuries occured in the following processes : process of percutaneous venepuncture for intra-venous injection and infusion(55.3%), medical examination and treatment(48.9%), per-cutaneous venepuncture for blood sampling (46.3%) and intra-muscular injection(42.2%). 3. The study showed that needle stick injuries occured before(19%), during(25%), and after (56%) client treatment. The major causes of needle stick injuries were perceived to be hastiness(82.2%) and carelessness(48.3%). Of these injuries, 91.8% occured in emergency situations. 4. Follow of care for the injury consisted of : treating the injured site immediately using disinfectants(89.7%), reviewing the clinical records of the patient involved(84.2%), immunological investigation for the status of antibodies(11.1%) and self-medication of antibiotics (10.7%). Only 16.3% of the total episodes were founded to have been reported to the administrative unit. 5. The length of clinical experience of the nurses, clinical specialty and length of clinical experience in physicians were found to have influenced the episodes of needle stick injuries ; nurses with less than 1 year and with more than 6 years of clinical experiences had significantly lower levels (X$^2$=25.04, P=.00), surgeons had significantly higher levels (X$^2$=9.89, P=.02) compared to that of internists and interns, higher(X$^2$=4.54, P=.03)than residents.

The purspoe of this study is to identify the socialization level of household work of the employed and unemployed housewives and it's related variables in order to provide some fundamental information for the rational and effective performation of the household task. For the purpose of this study, 700 questionnaire were distributed to the employed and unemployed wives who lived in Seoul. The data were analyed by the Frequency distribution, Percentile, t-test, F-test, Duncan's Multiple Range Test, and Multiple Regression Analysis. The main results were as follows : (1) Socialization level of household work of the employed wives was a little below medium point. When the household work was devided into three subdomains, in the domain of food and shelter, the socialization level was far below medium point. In the domain of clothes, the socialization level was a little higher than medium point. Socialization level of household work of the unemployed wives far below average. When the household work was devided into three sudbomains, in the domain of food, clothes and shelter, the socialization level was far below average, too. Socialization level of household work was significantly different according to the employment. (2) Among the background veriables, family income, household work helper, and frequency of leisure activities have a significant influence on the socialization level of the employed wives. Duration of marriage, housewife's education level and house income have a important effect on the socialization level of the unemployed wives background. (3) Among the background variabels of household work, performing competence of household work is powerful effect on the socialization level of the employed wives. And as for the unemployed wives, performing competence of household task and recognition of the velue of household work are significant variables. (4) The psychological variable such as sex-role attitude gave no noticeable influence on the socialization level of employed and unemployed wives. (5) In conclusion, classifing the variances influencing on the socialization level of household work in a measure of respcetive effect, it appears to be performing competence of household task, frequency of leisure activities, house income, sex-role attitued and educational level in the order of their influences for the employed wives. And as for the unemployed wives, it seems to be house income, educational level, performing competence of household work and frequency of leisure activities. To the two sides, the rate of explanation is shown at 35%.

In this study, breast milk levels of indicator polychlorinated biphenyls (PCBs) were estimated, and statistics drawn, for 22 Koreans in the general population, aged 26-38, who had resided in metropolitan areas for more than 5 years without occupational exposure to organochlorine pollutants. Concentrations of indicator PCBs were measured using the isotope dilution method with a high resolution gas chromatograph/high resolution mass detector, which provided accurate and precise data for investigation of trends, and international comparisons. The geometric mean of total indicator PCB levels was 22.3 ng/g lipid, which is significantly lower than the level in individuals from European countries. Overall, the geometric mean and 95th percentile of the most abundant congener PCB 153 were 8.04 ng/g lipid and 16.4 ng/g lipid, respectively. PCB congeners 138, 153 and 180 together accounted for about 75% of the indicator congeners analyzed. Breast milk total indicator PCB concentrations were significantly associated with age and parity, but not with body mass index (BMI), rate of body weight increase, or smoking habits. The geometric mean level of PCB 153 in breast milk from mothers with a pre-pregnant BMI < $21\;kg/m^2$ was significantly higher than in pre-pregnant women with a BMI of ${\geqslant}\;21\;kg/m^2$ (p<0.05). Women who ate more fish, meat, and milk products did not have significantly higher total indicator PCB levels than those who ate less of these products, but a significant difference in PCB 153 levels was demonstrated between the subjects consuming higher (11.45 ng/g lipid) and lower (6.79 ng/g lipid) amounts of fish (p<0.05), after adjusting for confounders. These results suggest that age, parity and fish intake are the important factors affecting the concentrations of indicator PCBs in these subjects.
