The experiment was conducted to obtain basic information on breeding of flue-cured tobacco varieties. Nine cultivars and partial diallel set of 36 F1 hybrides were grown at Taegu Experiment Station, Korea Ginseng & Tobacco Research Institute in 1983. Estimated heritability in the narrow-sense ranged from 66.21% to 94.12% for yield, leaves per plant, days to flower, leaf weight, leaf width, leaf shape, nicotine content and reducing sugar content, while that for stalk height, leaf length, midrib weight and midrib width ranged from 28.12% to 56.25%. The genotypic correlations were positive among yield, leaf weight, leaf length, leaf width, midrib weight and midrib width in the middle leaves, days to flower, nicotine content and reducing correlated with leaf length than leaf width. At the path coefficient analysis of the effect of leaf and midrib characters upon yield according to stalk position, leaf weight, leaf width and midrib width in the middle leaves, and leaf weight, and leaf width in the top leaves showed high direct effects.

Collagen, which accounts for one-third of human protein, is reduced due to human aging, and much attention is focused on making collagen into food to prevent such aging. Gel permeation chromatography with Reflective Index (RI) detection (GPC/RI) was chosen as the most suitable instrument to confirm molecular weight distribution, and we explored the use of this technique for analysis of collagen peptide molecular sizes and distributions. Data reliability was verified by matrix-assisted laser desorption/ionization coupled to time-of-flight (MALDI-TOF) mass spectrometric analysis. The data were considered meaningful for comparative analysis of molecular weight distribution patterns.

Tropical tasar silkworm, Antheraea mylitta is a commercial forest silkworm in India that produces tasar silk, but never experimented in Uttarakhand, a Himalayan state of India. A. mylitta express divergent phenotypic characters under different ecological conditions; so, we studied the effect of seven forest tree species in two rearing seasons on variability in silk gland weight of Daba (bivoltine) ecorace of A. mylitta at Forest Research Institute in Dehra Dun, Uttarakhand during 2012 and 2013. We used two-way completely randomized block factorial design and Post HOC Tukey's HSD test to analyse the collected data and there after carried out multiple regression analysis. Results indicated that silk gland weight differed significantly between rearing seasons (DF=1, F=2333.98, p <0.05), host plants (DF 6, F= 1516.25, p <0.05) and their interactions (DF=6, F=7.10, p <0.05). Higher silk gland weight was found in second rearing season than the first on all the host tree species. Terminalia alata fed A. mylitta larvae showed the highest silk gland weight of 8.03 and 9.47 g in first and second rearing seasons, followed by T. tomentosa (7.19 & 9.01g), T. arjuna (6.8 & 8.08 g) and L. speciosa (6.57 & 7.83 g) fed larvae, respectively. Post HOC Tukey's HSD test indicated that silk gland weight of L. speciosa and T. arjuna fed larvae in both the rearing seasons did not differ significantly. E.I. analysis also confirmed that T. alata, T. tomentosa, T. arjuna and L. speciosa are better in their order of merit than T. bellirica , T. chebula and L. tomentosa. Multiple regression analysis indicates that larval weight gain is a strong predictor (β=1.002, t=346.777, p = <0.05) for the silk gland weight of A. mylitta ; however, larval duration had significant negative regression weight (β=-0.270, t=-8.436, p = <0.05) on mean weight of silk gland.

This study was conducted to observe the relationship between diet and blood pressure for Korean(kangwha) and Nepali adolescents. 542 middle school students in Korea and 159 students in Nepal in the same age(14-15yr) group were investigated as the study subjects. Data for blood pressure as well as weight and diet were collected for the analysis. multiple regression analysis was employed to identify the influencing factors among the variables considered. As the results, the mean body weight of body weight of boys and girls in Kangwha was 54.5Kg, 50.6Kg which was 17Kg and 10Kg heavier than the weight of the Nepal students. Dietary survey result showed that there was no big difference in energy intake in Kangwha and Nepal students., Mean energy intake of Kangwha boys was 2, 848kcal and that of Nepal boys was 2, 720 kcal. The similar result showed significantly lower intake in other nutreints than that of Kangwha subjects whose consumption level was close to the Korean Recommended Dietary Allowances. The result of multiple regression analysis showed that weight was the greatest influencing factor on blood pressure both in Kangwha and in Nepal subjects. Nevertheless, after controlling the weight factor, there were axxociations observed between diet and blood pressure. And the relationship was stronger in case of Nepal than in Kangwha.

Objectives: This study was aimed to investigate the weight change of the high-risk group and the general maternal group and weight-relating factors in the early postpartum period. Methods: We retrospectively reviewed the medical records of those who received postpartum care from January 1, 2020, to December 31, 2020, in the postpartum care center affiliated with one Korean Medicine hospital. A total of 257 postpartum women's medical charts were included and divided into the high-risk group and the general maternal group. We investigated the weight changes and Body mass index (BMI) of the postpartum women and compared the difference between the two groups after taking the postpartum care. Finally, we used a Pearson correlation analysis to identify the weight-relating factors in the early postpartum period. Results: All the postpartum women showed the following results; 33.81±4.03 years old as the mean age; 22.23±3.28 as pre-pregnancy BMI; 58.21±9.18 kg of pre-pregnancy weight increased into 70.75±9.70 kg in the last month of pregnancy. Of the total 257 patients, 149 (58.0%) of high-risk pregnancy experience and 108 (42.0%) of general pregnancy were included. The edema index right after childbirth was significantly higher in the high-risk group than in the general maternal group (p<0.001), but there was no significant difference in BMI. After treatment with Korean medicine treatments, body weight, BMI, and edema index decreased significantly in both groups (p<0.01). As a result of correlation analysis, weight gain during pregnancy had a significant negative correlation with pre-pregnancy weight and pre-pregnancy BMI and a significant positive correlation with weight and BMI of the last month of pregnancy. In particular, pre-pregnancy BMI and body weight showed a significant negative correlation only in the high-risk group. Postpartum weight loss was significantly positively correlated with pre-pregnancy weight, pre-pregnancy BMI, weight & BMI of the pregnancy last month, weight gain during pregnancy, and decrease in edema (p<0.01) Conclusions: The weight during pregnancy of the high-risk group increased in inverse proportion to the pre-pregnancy BMI. The level of edema right after childbirth was significantly higher than that of the general maternal group, but showed a significant decrease after 2 weeks of Korean medicine treatments. Although it implicates the need for active Korean medicine treatments in the early postpartum period, further studies with controlled groups are needed.

Purpose: This study identified the effects of body weight control behaviors on bone mineral density (BMD) in Korean women aged 20 to 39 years. Methods: A secondary analysis of the 5th Korean National Health and Nutrition Examination Survey was conducted. Asian-Pacific criteria of BMI (Body Mass Index) and BMD were calculated for 1,026 women selected. The effects of body weight control behaviors were assessed using binary multiple logistic regression analysis while controlling for BMI. Results: Osteopenia and osteoporosis rates were 32.8% and 2.0%, respectively. About 69% of women performed weight control behaviors, and a combination of diet/exercise (22.7%) and drug added methods (10.9%) for weight control. Women who performed both diet control and exercise had a lower possibility to have abnormal BMD than those who did not try weight control (OR=0.67, CI=0.45~0.98, p=.039). Further weight control behaviors did not influence abnormal BMD. Conclusion: Body weight control should include proper diet and exercise in accordance with each woman's BMI level.
