Two experiments in the sequential order were conducted to determine the effects of different dietary lipid sources on the growth and fatty acid composition of rohu (Labeo rohita) and to examine the viability of a return fish oil finisher diet in restoring the human cardio-protective fatty acid profile. In the first experiment, fish were fed either with coconut oil (D1), olive oil (D2), sunflower oil (D3), linseed oil (D4) and fish oil (D5) as the main lipid source in the isonitrogenous diet for 90 days. No significant differences in growth were observed. Among the experimental diets moisture content of fish varied significantly (p<0.05) between the groups. Dietary lipid sources had a profound influence on the fatty acid profile of the muscle and liver as tissue fatty acid profile reflected the dietary fatty acid composition. Increased amounts of eicosapentaenoic acid and docosahexaenoic acid were observed in tissue of fish fed D4 and arachidonic acid was observed in the tissue of fish fed D3. We have also detected the metabolites of n-3 and n-6 pathway in D4 and D3 groups respectively, which prompted us to conclude that rohu, can desaturate and elongate $C_{18}$ essential fatty acids to $C_{20}$ and $C_{22}$ HUFA. A second feeding trial was conducted using the animals from the five different treatment groups for the duration of 30 days with fish oil rich diet (D5). Feeding with fish-oil rich washout diet resulted in the near equalization of all the other treatment groups tissue fatty acid profiles to that of fish oil (D5) fed group. These results indicate that a finishing fish oil diet can be effectively used to restore the human cardioprotective fatty acid profile in rohu fed with vegetable oils as lipid source.

In this study, elementary school students' satisfaction in school food service and their dietary behaviors were investigated, based on survey performed on 453 elementary school students (233 boy and 221 girl students) in the range of 4th grade to 6th grade. 85.7% of the students had agreed to the necessity of school food service. The point of overall satisfaction in school food service was $3.53{\pm}0.83$. The highest satisfactory factor was menu of school food service$(3.64{\pm}0.77)$, while the lowest satisfactory was service$(3.41{\pm}0.85)$. The point of boy students' satisfaction in menu(p<0.05), sanitation & facility(p<0.001), and service(p<0.05) of school food service was higher than girl students'. The students' responses indicate that: 36.9% of the students wash their hands before meal; 19.9% of the students brush their teeth after meal; 36.1% of the students arrange their table after meal; 22.1% of the students do not disturb others during their meal. 46.5% of the students always have meals pleasantly, while 22.8% of the students have meals without any particular feelings. 74.6% of the students always eat proper amount. 51.3% of the students turned out to eat snacks between meals out of hunger (50.7%) once a day with their friends(59.8%). 61.8% of the students believe that their tastes are affected by their parents and 57.8% of the students are aware of their unbalanced diet to be corrected. In summary, to provide satisfactory school food service for students, the improvements in the facilities and hygienic standard and the taste and nutrition have to be preceded, and the students have to be advised about the healthy dietary habits and the hazard of biased diet.

Purpose: This study compared the effects of a high glycemic load (high GL) diet and low glycemic load (low GL) diet on the body weight, body fat, blood pressure, and blood lipid indicators. Methods: Twenty-one young adults aged between 21 and 28 years who were overweighted or obese (body mass index [BMI] between 23 and 33.5 kg/㎡) before the study and after calorie reduction diets with either low GL or high GL for 2 weeks each were examined. The study was a randomized crossover design with a 2-week washout period between the 2 types of diet. The order of the low GL and high GL diet periods was randomized. The body weight, body fat, blood pressure, levels of blood lipids, fasting glucose, insulin, homeostatic model assessment (HOMA) insulin, C-peptide, and HOMA C-peptide were measured at the baseline, as well as 2, 4, and 6 weeks after starting the experiment. Results: When subjects were on the low GL diet, they lost more weight than those eating the high GL diet (mean ± SD, -2.77 ± 1.09 vs. -1.56 ± 0.78 kg; p < 0.001); there were greater decreases in body fat mass (-1.62 ± 1.19 vs. -0.88 ± 0.91 kg; p = 0.024) and BMI (-0.95 ± 0.32 vs. -0.56 ± 1.08 kg/㎡; p < 0.001). On the other hand, there were no significant differences in changes in biochemical parameters, such as blood lipids and fasting glucose levels, and blood pressure. The body weight, body fat mass, BMI, percent body fat, blood pressure, cholesterol (total, low-density lipoprotein, and high-density lipoprotein), fasting glucose, C-peptide, HOMA-insulin resistance-C-peptide levels were decreased significantly at 6 weeks. Conclusion: The low GL diet may be more effective in losing body weight, body fat mass, and BMI than the high GL diet for 2 weeks in healthy young overweight or obese adults.

Objectives : This study was performed to identify the efficacy and safety of ephedra and green tea mesotherapy on localized fat. Methods : Twenty-five healthy $20{\sim}35$ year overweight women (body mass $index{\geq}23kg/m^2$) were recruited and randomly assigned to two groups : experimental(mahuang and green tea) group (n=13), placebo(Normal saline) group (n=12). Total 8 times of herbarl mesotherapy treatment were performed once per week, 4 times were performed on right thigh (1st period), after wash-out for 1 week, the other 4 times were performed on left thigh (2nd period) without any modification of diet or exercise. Body composition, thigh circumferences were measured at each period before and after the intervention. Subcutaneous fat was measured by CT scan at before and after the 1st period of intervention and free fatty acid(FFA) was measured immediately before 1st intervention, 1 hour later, 24 hours later, and 7 days later. Satisfaction score and adverse events were evaluated. Results : In the subcutaneous fat, there were no significances, but in the circumferences. Experimental group had significant change when compared with placebo group (p<0.05). In FFA, experimental group has significant elevation at after 1 hour (p<0.05) evaluation. There were no serious adverse events in both groups. Conclusions : Experimental group had some significant findings in circumference, FFA, and had no serious adverse events comparing with placebo group, and no serious adverse events have been reported in both group. Mesotherapy with herb have a possibility of treating localized fat

The purpose of this study was to investigate and compare the general health behaviors of elementary school children in single- and two-parent families and to identify factors affecting health behavior. The study subjects were 1,023 students attending S elementary school in G province. Data was collected from March 5, 2018 to March 16, 2018. Collected data was analyzed using descriptive statistics, the chi-square test, and logistic regression analysis using SPSS/WIN Ver. 22.0. The results of children with a single-parent mother were significantly different for 'regular breakfast' (p=.015) and 'counseling with homeroom teachers' (p=.019), and the results of children with a single-parent father were significantly different for 'wash hands before going out and before meals' (p=.035), 'someone you can talk to when you are worried' (p=.005), and 'often lonely and depressed' (p=.007). Logistic regression analysis showed that children with single-parent families were 7.670 times more likely to seek 'counseling with homeroom teachers' than children with two-parent families (p=.011). The results of this study provide basic data on the health behaviors of elementary school students with single-parent families.

Index of health practice of personal hygiene can be summarized as follows. A. A case of middle school students. 1) The percentage of health practice index in male and female was 49.6% and 48.1% respectively. Index of female students was higher than that of male students. 2) As for parent's occupation, public servants and company emplyee was upper level. Farming was low level. 3) As for income level, middle, level with 56.5% was highest in high income level and low level with 27.4% was highest in low income level. B. A case of high school students. 1) Middle level of health practice index was 46.0% of male students, upper and low level was 32.4% and 28.0% of female students respectively. 2) Middle level of health practice index was high in farming and company employee and upper level was high in commerce and service, low level with 60.0% was high in unemployed. 3) Upper practice index 35.7% appears in the rich and low practice index 38.3% appears in the poor. 13. Average points of Health practice about personal hygiene were as follows. (Full marks at 4). A. A case of middle school. Female (1.87 point) was higher than male (1.26 point). Night time (2.03 point) was higher than day time (1.66 point) and middle or small cities (2.17 point) are high than any other places. As for parent's occupation, students whose parents are company clerk get high marks (2.32) and ten students whose parent's job are service get next high marks (2.20). B. A case of high school. Female (1.53 point) was higher than male (1.22 point), as parents educational level were higher the point were higher, and as income level was higher, the points of health practice (1.78) were higher, and as for parents occupation, service get highest point (1.93) and commerce get next high point (1.86) public servant get low point (1.66). 14. The percentage of experience in smoking was 11.9% of middle school students and 60.9% of high school students. 15. The percentage of experience in inhalation of bond and administrating LSD was 4.3% of male middle school students, 8.4% of female middle school students, 6.9% of male high school students and 4.2% of female high school students. The knowledge level of communicable disease infection are very low in middle and high school students and practice level of personal hygiene are also very low. As a whole we can evaluate that middle and high school students are low level of health knowledge and practice. In conclusion, we must consider preparation for school health education program through establishing of health subjects in the carriculum, and securing of health education teachers and using materials and media program of health education. It is very important to establish macroscopic policy and strategy for public health education and to get people have right knowledge and practice for health.
