One of the most important limiting factors for the production of the grafted cactus in Korea is the qualitative and quantitative yield loss derived from stem rots especially caused by Bipolaris cactivora. This study is aimed to develop microbial control agents useful for the control of the bipolaris stem rot. Two bacteria (GA1-23 and GA4-4) selected out of 943 microbial isolates because of their strong antibiotic activity against B. cactivora were identified as Bacillus subtilis and B. amyloliquefaciens, respectively, by the cultural characteristics, Biolog program and 16S rRNA sequencing analyses. Both bacterial isolates significantly inhibited the conidial germination and mycelial growth of the pathogen with no significant difference between the two, of which the inhibitory efficacies varied depending on the cultural conditions such as temperature, nutritional compositions and concentrations. Light and electron microscopy of the pathogen treated with the bacterial isolates showed the inhibition of spore germination with initial malformation of germ tubes and later formation of circle-like vesicles with no hyphal growth and hyphal disruption sometimes accompanied by hyphal swellings and shrinkages adjacent to the bacteria, suggesting their antibiotic mode of antagonistic activity. Control efficacy of B. subtilis GA1-23 and B. amyloliquefaciens GA4-4 on the cactus stem rot were not as high as but comparable to that of fungicide difenoconazole when they were treated simultaneously at the time of pathogen inoculation. All of these results suggest the two bacterial isolates have a good potential to be developed as biocontrol agents for the bipolaris stem rot of the grafted cactus.

This study was done to compare serum levels of lipids, trace minerals, ceruloplasmin and ferroxidase activity between female college smokers and nonsmokers. Serum levels of lipids, Cu, Zn, ceruloplasmin and ferroxidase activity were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Serum levels of TG, total cholesterol and HDl-cholesterol were measured using test kits. Serum Cu Zn were determined by the AAS. Serum ceruloplasimin level and ferroxidase activity were determined by spectrophotometric methods. All data were statistically analyzed by the SAS PC package program. Mean and standard errors were calculated for each item, and the significance of the difference between two groups was evaluated by Student's t-test at p〈0.05. There was no significant difference in levels of total cholesterol, TG, VLDL-cholesterol, LDL-cholesterol, LDL/HDL and atherogenic index, but HDL-cholesterol level was significantly lower(p$\ll$0.05) in female college smokers than in nonsmokers. Serum zinc level showed no significant difference, whereas copper level was significantly higher in smokers, consequently yielding higher Cu/Zn ratio in smoking college women. Ceruloplasmin level was 32.6mg/dl in smoking college women, which was significantly higher(p$\ll$0.05) than that of 28.6mg/dl in nonsmokers. However, cerulopasmin ferroxidase activity, 0.34U/mg in nonsmokers was higher(p$\ll$0.05) than that of 0.29U/mg in smokers. From these results, it is confirmed that cigarette smoking itself has a very detrimental effect on health and mineral nutritional status although the smoking history is relatively short among college women(pack-years=1.7).

Atopic dermatitis (AD) is believed to be associated with the intake of antioxidant nutrients and fatty acids due to its immunological dysfunction. The purpose of this study was to examine the effects of nutrition education promoting vegetable, fruit, and fish intake on the severity of AD in children. Children with AD aged 6 months to 5 years were randomly assigned into education and control groups, and followed for 1 year. Seventy-six children completed the study (38 for control, 38 for education). The education group received education promoting the intakes of antioxidant-rich foods (vegetables, fruits) and n-3 fatty acid foods (fish). A 24-hour food recall was collected for the diet information. After education, all vegetables (p < 0.001), fruits (p < 0.01), and fish (p < 0.05) intakes per 1000 kcal increased significantly in the education group, whereas only vegetable intake increased in the control group (p < 0.001). The SCORAD index, the severity of atopic dermatitis, decreased significantly in the education group (p < 0.05). Increased consumption of dietary vitamin E was significantly associated with reduction in the SCORAD index, after adjusting for age and gender (p < 0.05). A nutritional education program to increase vegetable, fruit, and fish intake may be effective in reducing the severity of AD, and vitamin E intake may be associated with the decreased severity of AD. More controlled studies on the relationship between these intakes and severity of AD, with intensive diet and/or supplement intervention programs, are needed to obtain conclusive results.

This survey was carried out to Investigate the effect of the daily average nutrient intakes, self-consciousness of nutrition knowledge and health on the nutrition knowledge and food habits between college women and their own mothers, Questionnaires were completed by 214 college women who do major in nutrition and by 173 their mothers. The college women scored significantly higher than that of their mothers In the nutrition knowledge. And their mothers scored significantly higher than that of college women in the food habits. Most of the subjects belonged to 'Fair' food habit group, which was considered to be relatively good. The correlation of the scores between nutrition knowledge and food habits of the college women and their mothers was low. The daily average nutrient Intakes of all women were higher than the recommended dietary allowance except for that of Iron. There was a significant and negative correlation between the nutrition knowledge score and daily average nutrient intakes in college women. But there was not a significant correlation in the nutrient intakes in their mothers. And also there was a significant and positive correlation between food habits score in their mothers but there was not a significant correlation score in college women. The higher the women had a self-consciousness of health, the higher their mothers had a food habit score, but they had daily average nutrient intakes were lower than their daughter's(college women), And the women that had a self-consciousness of health were healthier, daily nutrient intakes in their own mothers were higher in the food habits scores than that of the college women. The main curriculum for a good food habits is that it is important that one has a responsible nutrition education. For the improvement of nutrition education program we should transmit the nutritional information through an effective mass media(i. e. Radio, TV, Newspaper).

Eating breakfast provides crucial nutrition for brain function and helps promote overall health. It is especially critical in growing adolescents, as it is known to form good eating habits and better study habits. This study investigated the effects of skipping breakfast on nutritional state, fatigue level, and attention level. A cross-sectional study was conducted in 2010 on total of 828 adolescents composed of 414 boys and 414 girls. Students who ate breakfast never to twice per week were placed in the breakfast-skipper group while students who ate breakfast more than five times per week were included in the breakfast-eater group. Students performed a self-reported questionnaire on food behaviors, amount of food consumption, fatigue level, attention deficient hyperactivity disease (ADHD) level by Conners-Wells' Adolescent Self-Report Scales, depression scale, and self-esteem level. Statistical analysis was conducted using the SAS program (version 9.1). A total of 135 boys (32.6%) and 138 girls (33.3%) were included in the breakfast-skipper group, whereas 241 boys (58.2%) and 223 girls (53.9%) were included in the breakfast-eater group. The breakfast-skipper group showed irregular food behaviors and lacked nutrients. Specifically, energy (p< .001), protein (p< .001), dietary fiber (p< .001), calcium (p< .01), vitamin A (p< .01), thiamin (p< .05), niacin (p< .001) levels in boy breakfast-skippers were statistically lower compared to boy breakfast-eaters. Intakes of all nutrients except fat in girl breakfast-skippers were statistically lower than in girl breakfast-eaters. Girl breakfast-skippers (41.3%) showed significantly higher fatigue risks compared to girl breakfast-eaters (21.5%). Low attention level was also observed only in girls in the breakfast-skipping group. Moreover, students in the breakfast-skipper group showed higher scores for depression and low self-esteem (p< .001). In conclusion, skipping breakfast has effects on young adolescents' nutrition, manifesting as high fatigue level and low attention level, especially in girls.

This study was conducted to investigate the meal quality and dietary behaviors of low-income family children by qualitative method. The subjects were 12 children(2 boys and 10 girls) aged 7 to 11, enrolled in an after-school care center in Kimpo, Gyeonggi province. Most of their mothers had jobs(83.3%) and 75% were the beneficiaries of a government assistance program. When compared using body mass index(BMI) percentile, 16.7% of the subjects were classified as being overweight. The food intake patterns and meal qualities were evaluated from dietary records for three non-consecutive days. The mean dietary diversity score(DDS) was 3.8, suggesting at least one food group was deficit. Only 8.3% of the records indicated a satisfactory intake of all five food groups, and fruit was the most deficit food group(58.3%). Also, the proportion of balanced of meals was low, especially breakfast(36%), in that main dish(the source of protein) was not included. The children had problematic eating behaviors, such as an unbalanced diet, eating meals in a hurry, skipping breakfast, and irregular meal times. They answered that they liked to eat simple meals and convenient foods. In conclusion, nutrition education should incorporate strategies to reach families and help with meal planning and management, as well as modifying the eating behaviors of children, in order to improve nutritional status.

The purpose of this study was to investigate the prevalence and to identify the related factors of overweight among young children. The study subjects were 138 children, aged 3-5, attending child care centers in the Kyungbuk area. We assessed a wide range of collected variables including general characteristics, anthropometric data, dietary habits, stress, food preferences, and food frequencies of young children, and anthropometric data and general characteristics of their parents. The results of this study were analyzed with $\chi$$^{2}$_ or t-test using SPSS package program. The subjects were classified into two groups using the weight for length index WLI criteria: normal group(n=101) and overweight group(n=37). Forty-nine percent of mothers of overweight children did not recognize their child's current overweight status. Scores for encountering criticized-violent situation stress, hurt-pride stress and total stress were higher in the overweight group than in the normal group. The frequency of snacking and the appetite of the overweight group were increased compared to those of the normal group. The overweight group had higher preferences for salad, kimbab, boiled rice with meat, vegetables and Chinese noodles, chicken, shell, banana, soybean milk, hotdog, and potato than the normal group. The overweight group showed higher consumption frequencies of pan-fried foods, egg, laver and strawbery compared to the normal group. Therefore, our results suggest that obese young children, as well as their parents, need more nutritional counseling education about dietary habits, food preference, recognition of normal weight and strategies for actively coping with stresstopreventandtreatobesityandtomaintainhealth. .

Objectives: Obesity is regarded as one of the most prominent health threats worldwide and a serious risk factor for non-communicable diseases, such as diabetes mellitus type 2, high blood pressure, cardiovascular diseases, and some types of cancer. Given the role that societal development-as reflected by the Human Development Index (HDI)-may play in the prevalence of obesity and overweight, this study aimed to investigate the degree to which the prevalence of obesity and overweight is affected by HDI and its components. Methods: In this ecological study, the required data on HDI and its components were gathered from the latest report of the United Nations Development Program, and data on obesity and overweight were acquired from the latest reports published on the World Health Organization website. Statistical analyses were conducted using SPSS version 24.0. Results: The prevalence of obesity was determined to be significantly higher among females than males, and the gross national index per capita was found to be significantly higher for males than females (p<0.05). Significant positive correlations were found between HDI and its components and sex, as well as indices of obesity and overweight. Conclusions: A significant positive correlation exists between HDI and obesity. As policy-makers attempt to improve the general welfare of the people, they should be aware of potential unwanted effects of development on the risk of obesity and overweight among the population.
