This study attempts to analyze the relationship between various job-related factors and the intent to turnover of employees working at different types of hospitals/clinics in urban and rural areas. The data was compiled from 1,506 employees in 21 hospitals and 10 clinics located in Kyung-gi Do. Korea, using a self-administered questionnaire. Major findings are as follows: 1) The intent to turnover was higher for the employees of small hospitals located in rural areas. It was also higher when the employees were less than 30 in age, female, single, had not received college education, and had worked for 2-5 years in their hospitals. 2) An important factor affecting the intent to turnover was job satisfaction, which in turn had a strong correlation with the job itself(opportunity of utilizing abilities and skills, subjective value attached to the current job, sense of accomplishment) and had a rather weak correlation with salary, supervision, promotion and co-worker relationship. 3) In the analysis by job category, it was found that, besides job satisfaction, the intent to turnover was significantly affected by the job itself in case of administrative personnel and by the level of salary in case of nurses. 4) For a successful management of turnover, hospitals need to develop (a) programs for improving adaptive abilities of 'new' employees(who have worked for less than 2 years), and (b) for the other employees(who have worked for more than 2 years), strategies for enhancing job satisfaction by providing the environment where they can show their maximum abilities.

Objectives: This study evaluated dietary intake and food sources of essential fatty acids in Korean adolescents. Methods: This study was comprised of 3,932 adolescents (9-18 years) who participated in the 2016-2021 Korea National Health and Nutrition Examination Surveys. Dietary intake and food sources of essential fatty acids, including alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and linoleic acid (LA) were evaluated using data obtained from one-day 24-hour dietary recall. The proportions of adolescents consuming ALA, EPA + DHA, and LA above or below the adequate intake (AI) of the 2020 Dietary Reference Intakes for Koreans were calculated. All statistical analyses accounted for the complex sampling design effect and appropriate sample weights. Results: The mean intakes of ALA, EPA, DHA, and LA among Korean adolescents were 1.29 g/day, 69.6 mg/day, 166.0 mg/day, and 11.1 g/day, respectively. Boys had higher intakes of all essential fatty acids compared to girls. By age group, adolescents aged 15-18 years showed lower intakes of EPA and DHA compared to adolescents in younger age groups. The 9-11-year-old adolescents had lower intakes of ALA and LA than older adolescents. The proportions of adolescents who consumed more than AI were 35.7% for ALA, 30.4% for EPA + DHA, and 41.5% for LA. Adherence to the AI for ALA did not differ by sex or age group, although boys showed a lower adherence to the AI for EPA + DHA than girls. Major food sources for ALA and LA were plant-based oils, mayonnaise, pork, and eggs. Mackerel was the most significant contributor to EPA and DHA intake (EPA, 22.6%; DHA, 22.2%), followed by laver, squid, and anchovy. Conclusions: The proportion of Korean adolescents who consumed EPA + DHA more than AI was low. Our findings highlight that nutrition education emphasizing an intake of essential fatty acids from healthy food sources is needed among Korean adolescents.

Background : Hypercholesterolemia is a major independent risk factor of coronary heart disease. Practice guidelines for management of hypercholesterolemia had been made in several developed countries. This study was undertaken to assess the effect of practice guideline reminders and flow-sheets to improve the quality of management of hypercholesterolemia. Methods: Practice guideline reminders and flow-sheets based on National Cholesterol Education Program Adult Treatment Panel II guidelines, were placed on the office desks of outpatient department of family medicine at the Asan Medical Center. Before this intervention, we educated the doctors to use these reminders and flow-sheets. The charts of all patients who had cholesterol levels greater than or equal to 240 mg/dl during 4 months before and after introduction of reminders and flow-sheets, were reviewed retrospectively. We compared the performances of physicians about management of hypercholesterolemia between pre-intervention period and post-intervention period. Results: The detection rate of hypercholesterolemia in post-intervention period was increased to 83.2% compared by 71.5% in pre-intervention period. Risk factor analysis for coronary heart disease increased significantly from 16.9% to 68.7%. Adequacy of management was 19.2% in pre-intervention period and 78.0% in post-intervention period. It showed statistically significant improvement in management of hypercholesterolemia. Conclusion : This study suggested that practice guideline reminders and flow-sheets were the effective methods in improving the quality in management of hypercholesterolemia.

Purpose: This study was conducted to evaluate the association between intakes of potassium, magnesium, and calcium and diet quality in ischemic stroke patients. Methods: This study analyzed data from 285 subjects recruited from February 2011 to August 2014 in Seoul, Korea. Nutrition intakes were obtained from a semi-quantitative food frequency questionnaire composed of 111 food items. The subjects were divided into 4 groups by quartiles according to intakes of potassium, magnesium, and calcium. Index of Nutritional Quality (INQ), Mean Adequacy Ratio (MAR), and DQI-International (DQI-I) were analyzed for assessment of diet quality. Results: We found a positive association of intakes of these three minerals with MAR and DQI-I after adjustment for age, sex, education level, smoking, atrial fibrillation, and total energy intake. However, total moderation of DQI-I score in the Q4 group was significantly lower than that of the Q1 group. The age, sex, education level, and smoking, atrial fibrillation, and total energy intake-adjusted odds ratios of extensive cerebral atherosclerosis were inversely associated with intake of magnesium (Ptrend = 0.0204). However, this association did not exist with intakes of potassium and calcium. Conclusion: Potassium, magnesium, and calcium rich and high quality diet could be associated with decreased risk of ischemic stroke, in part, via effect on extensive cerebral atherosclerosis.

To identify "Gongsik", defined as food-sharing by picking food from a common plate using personal utensils, we conducted 7 focus group interviews including 47 university students during a 6 month period. Focus group discussions were audio taped, transcribed, and categorized into major themes. We divided Gongsik into the following categories: practical reasons, socio-psychological reasons, boundaries, suppressive situations, emotional characteristics, attitudes towards using different utensils, and future prospects. Gongsik appeared to be useful for fostering quick food sharing, intimacy and solidarity, and a fixed behavior learned at home. If the amount of food was too small to provide individual servings, as in Jjigae, Gongsik was likely to occur spontaneously. Family, close relatives, friends, and lovers sharing common activities and/ or blood ties were composed the boundaries of Gongsik. However, Gongsik was avoided in elegant restaurants or in view of foreigners. Participants showed mixed feelings towards Gongsik. Gongsik conducted with a spoon was considered to increase the degree of suggested intimacy in a food sharing context. Half of the students believed that the practice of Gongsik would be maintained into the future. Gongsik is a culturally-specific behavior that includes both positive and negative meanings. Aside from improving understanding of the cultural aspects of food-sharing, we suggest that the negative aspects of Gongsik related to the issue of hygiene be considered in food and nutrition education.

Purpose: The hepatitis B virus is a major cause of chronic liver disease. The clinical guidelines recommend that inactive chronic hepatitis (ICH) patients also check their liver function every 6 to 12 months and manage the potential risks. This study compared the hepatitis B knowledge, self-care practice, and quality of life in patients with HBV according to the disease activity. Methods: This study was conducted in a university hospital and surveyed on 65 ICH patients and 68 progressive chronic liver disease (PCLD) patients from November in 2012 to September in 2013. Results: The knowledge of hepatitis B was lower in the group of a lately perceived HBV infection and ICH. Self-care practice was lower in the male and the patients group with a perceived HBV infection within 5 years. The "taking regular liver function test" score was lower in the ICH. Eight out of 12 Liver Disease Quality of Life instrument (LDQOL) subscales were lower in PCLD. Conclusion: The hepatitis B knowledge and self-care practice are relatively lacking in ICH and the patients group with a perceived HBV infection within 5 years. More effective education programs will be necessary to enhance the hepatitis B knowledge and self-care for patients with HBV and even for ICH.

Cervical cancer is a major public health problem in Thailand, being ranked second only to breast cancer. Thai women have been reported to have a low rate of cervical cancer screening (27.7% of the 80% goal of WHO). We therefore aimed to apply the social marketing theory and health belief model in promoting cervical cancer screening in Kanthararom District, Sisaket Province. A total of 92 from 974 targeted women aged 30-60 years were randomly divided into two groups. The experimental group underwent application of social marketing theory and a health belief model program promoting cervical cancer screening while the control group received normal services. Two research tools were used: (1) application of social marketing theory and health belief model program and (2) questionnaire used to evaluate perceptions of cervical cancer. Descriptive and inferential statistics including paired sample t-test and independent t-test were used to analyze the data. After the program had been used, the mean score of perception of cervical cancer of experimental group was at a higher level (${\bar{x}}=4.09$; S.D.=0.30), than in the control group (${\bar{x}}=3.82$; S.D.=0.20) with statistical significance (p<0.001). This research demonstrated an appropriate communication process in behavioral modification to prevent cervical cancer. It can be recommended that this program featuring social marketing and the health belief model be used to promote cervical cancer screening in targeted women and it can be promoted as a guideline for other health services, especially in health promotion and disease prevention.

This study was analyzed the characteristics on the stability of posture while conducting a through two and half rotation technic of pench$\acute{e}$ in rhythmic gymnastics. Two rhythmical gymnastics player(LKH and SSJ) who is a member of the national team were selected, and for obtain the kinematic and kinetic variables were used a ProReflex MCU 240 infrared camera(Qualisys, Sweden) and a Type9286A force platform(Kistler, Switzerland). The mechanical factors were computed by using Visual3D program and Matlab R2009a. During the landing and rotation phase the results showed following characteristics; 1) In medial-lateral and horizontal displacement of the support foot, LKH showed smaller movement than SSJ, but SSJ showed smaller movement than LKH in swing foot. LKH showed bigger movement in medial-lateral axis of COP and vertical axis of COG, but SSJ showed bigger movement in horizontal axis of COP and medial-lateral axis of COG. 2) SSJ showed bigger maximum horizontal and vertical velocity at P1 and P2 than LKH. 3) In the inclination angle of COP and COG, SSJ showed smaller change than LKH, but within medial-lateral tilt of the shoulder, LKH performed rotation motion in horizontal position than SSJ. There was no differences in each force components during rotation, but on landing phase, the results showed a characteristic that SSJ exerted bigger breaking force and vertical force than LKH.

The purpose of this study was to estimate the mineral intakes and serum mineral levels of pregnant and lactating women. The subjects consisted of 34 non-pregnant, 56 pregnant and 20 lactating women. Nutrients intakes were investigated by the 24-hr recall method, and serum major and trace minerals were analyzed by the ICP-spectrometry. Calcium (Ca) and zinc (Zn) intakes were observed lower than RDA especially for both pregnant and lactating women. Iron (Fe) intake of pregnant women was $85 - 139\%$ RDA through Fe supplementation, and that of lactating women was lower than RDA. Compared with non-pregnant women, the pregnant women had similar Ca intake and higher magnesium (Mg) intake. Comparing with the non-pregnant women, serum Ca level in pregnancy was lower, and that of lactating women was not significantly different. Serum phosphorus and Mg levels were not significantly different among the groups. Serum Fe level of pregnant and lactating women was lower than that of the non-pregnant women. Serum Zn level of pregnant women was lower than those in the lactating and non-pregnant women. Serum copper level decreased as the pregnancy progressed. Serum sodium (Na) level was higher in 2nd- and 3rd trimester and potassium (K) level was higher in 3rd trimester and lactating period than other groups. Na/K ratio was not significantly different among the groups. During all periods, there was no correlation between dietary intakes and serum levels in each minerals. Serum Ca level positively corrleated with serum Mg level, especially in 3rd trimester and lactating women. In general, serum mineral levels in pregnancy were changed compared to the levels in non-pregnancy and restored in lactation to the levels for non-pregnancy.
