  • The seeds of 16 domestic plants were studied for their moisture, total lipids and fatty acid composition. Of the 16 seeds, chestnut, corn, mungbean and ginko nut yielded less than 9% by weight of total lipids compared to others that gave 20-73%. The identified fatty acids from the seed lipids ranged from lauric acid (12:0) to lignoceric acid(24:0). It was intended in this study to classify the seed lipids according to their major fatty acids: Group t-Oleic acid; Group 2-0leic acid and linoleic acid; Group 3-linoleic acid; Group 4-linolenic acid ; Group 5-erucic acid ; Group 6-ricinoleic acid. The saturated fatty acid content of mungbean (33%) was the highest among the seed lipids studied. The highest value for the P/S fatty acid ratio(10) was in perilla.

  • Purpose: To evaluate the effect of a gymnastics program for eight weeks to maintain better body composition and decrease fatigue among factory workers. Methods: Data were collected in 54 female workers in their 50s and 60s in a factory located in the S city of the K region between April and July in 2019. The subjects were divided into two groups: 1) experimental group (n=27) received a 30 minute-gymnastics program three times per week, and 2) control group participated in lecture series about the principle and effect of the gymnastics program. Body composition and fatigue levels were measured before and after the intervention and analyzed using the SPSS 23.0 program. To evaluate the differences in demographic and clinical characteristics between the experimental and control groups, the chi-squared test and the t-test were used. Repeated measures two-way ANOVA was performed to evaluate the change between outcomes of the pre-and post-investigation. Pairwise comparisons were used to assess the differences between the groups and the time. Results: There are statistically significant differences in body fat mass (p<.001), body fat percentage (p<.001), basal metabolic rate (p<.001), and body mass index (p<.022) in the experimental group compared to the control group. In particular, there is a significant interaction between the groups and the time in body fat mass (F=6.308, p=.015), basal metabolic rate (F=11.397, p=.001), fatigue (F=6.933, p=.011). Conclusion: Our findings suggest that using the gymnastics program helps women in their 50s and 60s who work in factories promote better body composition and reduce fatigue levels.

  • The influence of tobacco additives on the composition of the combustion products in mainstream smoke is discussed. The effect of additives on the chemical composition of smoke have been further evaluated in order to discover additives that would alter the chemical composition of smoke. Tobacco was uniformly treated at a 1-5$\%$ level with 8 classes of additives. Group M treated with alkali metal salt and group S, F, O give lower tar, nicotine and CO values than the control. Group AN treated with natural antioxidant gives higher tar and CO values than the control. The increases are most probably due to the high transfer rate of the ingredients to smoke. M3 and P1 reduced above the $50\%$ of TSNA from the smoke. M4 and P1 reduced above the $50\%$ of HCN from the smoke. These results suggest that tobacco additives alter pyrolysis or combustion product distribution and provide fundamental data to lead the development of a RRP(reduced risk product).

  • This study was performed to investigate nutritional intakes and preference food and blood composition of female college students of premenstrual syndrome. Based on physical measurement test results, both groups showed no noticeable difference and both groups were within the normal range according to body composition analysis. In terms of nutrients consumption, results showed nutritional intakes more than EAR(estimated average requirements) included phosphorus>vitamin $B_6$>vitamin $B_1$, while nutritional intakes less than EAR were vitamin A>vitamin $B_6$>calcium>folic acid. A significant difference was observed for vitamin C intake(p<0.05). The overall mean values of basic blood(WBC, RBC, Hct, and Hb), sex hormone(Estrogen, Progesterone), aldosterone, cortisol, Cu, Zn, and Ca, Mg indices in female college students were within the normal range and there was no significant difference between the PMS group and the Normal group. In conclusion, vitamin C intake of the PMS group showed a level of 84.8% EAR. Therefore vitamin C supplement can be beneficial to relieve the PMS Syndrome.

  • Objectives: Many symptoms of cold and heat patterns are related to the thermoregulation of the body. Thus, we aimed to study the association of cold and heat patterns with anthropometry/body composition. Methods: The cold and heat patterns of 2000 individuals aged 30-55 years were evaluated using a self-administered questionnaire. Results: Among the anthropometric and body composition variables, body mass index (-0.37, 0.39) and fat mass index (-0.35, 0.38) had the highest correlation coefficients with the cold and heat pattern scores after adjustment for age and sex in the cold-heat group, while the correlation coefficients were relatively lower in the non-cold-heat group. In the cold-heat group, the most parsimonious model for the cold pattern with the variables selected by the best subset method and Lasso included sex, body mass index, waist-hip ratio, and extracellular water/total body water (adjusted R2 = 0.324), and the model for heat pattern additionally included age (adjusted R2 = 0.292). Conclusions: The variables related to obesity and water balance were the most useful for predicting cold and heat patterns. Further studies are required to improve the performance of prediction models.

  • This study was carried out to investigate the relative influence of food intake and menopause on the body composition and bone quality index of women in Wonju who were voluntary participants in a community nutrition program. The status of food intake was examined using a semi-quantitative food frequency questionnaire. A bioelectrical impedance analysis tool (Inbody 2.0) and SONOST 2000 were used for estimating body composition including criteria such as TWB (Total body water), SLM (Soft lean mass), LBM (Lean body mass), PBF (% body fat) and WHR (Waist hip ratio), and BQI (Bone quality index). 82% of the subjects were over the age of 40. The percentage of overweight subjects was 64.3% overall, and higher in the advanced age group while underweight was prevalent in younger subjects. Although only 8.6% of the total subjects skipped breakfast, this habit was more prevalent in subjects in their twenties and the underweight group. Variables, such as age, menstruation status, and breakfast eating habits were significant factors considered in relation to food intake from 7 food groups. Generally, older aged women ate more vegetables while the younger group consumed more simple sugars and lipids. The subjects who were underweight or skipped breakfast tended to drink higher amounts of soft drinks. With increasing age, BMI, PBF and WHR increased also, and TWB, SLM, LBM, and BQI decreased. According to correlation analysis, WHR has a positive correlation with PBF. BQI correlated with SLM and LBM positively, and with PBF and WHR negatively. Over 93.3% of the subjects over the age of 30 were assessed as having abdominal obesity. It was revealed that body composition was affected not only by age, obesity degree and menstruation status but by various food intake habits. Body composition including WHR and BQI had put many of the subjects' health in danger of metabolic disorders. Therefore, it is important to emphasize keeping in place some helpful habits such as eating regularly, having a proper diet which includes many vegetables, and continued milk intake even after menopause to insure women's good health.
