Purpose: The purpose of this study was to examine the association between health behaviors and health-related quality of life (HRQOL) among vulnerable children in a community. Methods: Using data from 'The Obesity Prevention Framework for Vulnerable Children', a secondary analysis was conducted for 165 children (ages 8~12 years) and their parents who were recruited from 16 K-gu Community Child Centers in Seoul. Six types of health behaviors related to eating and activity were assessed. Each behavior was categorized into the non-recommended vs. recommended levels. The scores of the recommended levels of the six health behaviors were summed up for the composite score of health behaviors. HRQOL was measured by KIDSCREEN-52. Results: The groups with a non-recommended level of fast food intake and sedentary behavior had a significantly lower total score of KIDSCREEN-52 than those with a recommended level. Moreover, the lower composite score of health behaviors was significantly associated with the lower total score of KIDSCREEN-52. Conclusion: Among the vulnerable children, the six recommended health behaviors and their composite score were in significant positive associations with the HRQOL levels. Therefore, nursing strategies for enhancing the recommended levels of health behaviors are needed for vulnerable children.

This experiment was carried out to define the effects of application amounts of the chemical fertilizers on plant growth and yield of the ginger. The results obtained are summarized as follows. Plant height of the ginger was 45.3 cm at lower level of fertilizer, 52.6 cm at recommended level, and 49.4 cm at higher level. Leaf area, stem number, and stem diameter were more significantly increased at higher level of fertilization compared to recommended rate. Dry weight of shoots and rhizomes were significantly increased with the increase of fertilization level. Stem number, stem diameter, leaf area, dry weight of shoots, and fresh weight of rhizomes were positively correlated with the amounts of fertilizer applied. Yield of rhizomes were 1, 653 kg at lower level of fertilizer, 2,248 kg at recommended level and 2,428 kg at higher level, respectively. Ginger yield showed 7.4% higher at higher level of fertilization compared to recommended rate.

This study compared the recommended levels of illumination for housing. KS Recommended Levels of Illumination (KS A 3011) in Korea, Recommended Levels of Illumination (GB 50034-2004) in China and Recommended Levels of Illumination (JIS Z 9110) in Japan are compared. The results are as below. First, recommended levels of illumination used in Korea China Japan are suggested by different locations and activities. However, classification for application scope is set differently. There are 10 areas for classification used in Korea, 5 areas in China, and 13 areas in China. When medium levels for classification are included as classification level, total of 15 areas are used for classification in China. Second, when considering there are 15 areas of application scope in China for recommended levels of illumination, there are 7 areas that are commonly used in Korea China Japan. 7 areas include stadium, factories, hospitals, office, shopping center, houses and hospitals. Third, working surface is considered as the height for recommended levels of illumination in Korea China Japan. Korea and Japan consider all working positions, standing and sitting position, when deciding the height. However, China only considers the standing position. Fourth, application scope for recommended levels of illumination for housing are classified in 16 areas in Korea, 5 in China and 18 in Japan. Thus, the application scope for recommended levels of illumination in housing in Korea is similar to Japan. However, there are only 5 areas used in China such as living room, bedroom, dining room, kitchen and sanitary room. Fifth, recommended levels of illumination is classified in 3 levels such as Lowest-Moderate-Highest while China and Japan only have standard recommended levels of illumination. Sixth, when observing recommended levels of illumination by type of activities, Japan classified the activities in greatest detail followed by Korea and then China. Seventh, Recommended levels of illumination differs by each country.

Age, sex and the amount of activity determine recommended dietary allowances. So the method of developing RDA and their levels have been revised according as the physical condition of a nation improves and the amount of activity changes along with the variety of social situations. It can be seen from records that in Korea the absolute nutrient requirements for the people in Chosun Dynasty were first published in 1922. After that, in 1941 Gui Dong Han expressed his view that the standard health diets for the Japanese would be suitable for the people in Chosun Dynasty. In 1960, the temporary nutrition standards for the Koreans were established by the Ministry of the Health and Social Affairs. For these standards, males and females were respectively divided into three groups by age and nine nutrients were recommended for each group. In 1962, The Korean Association to FAO published the RDA for the Koreans. Since then, regular researches have been done. For these allowances, there were 16 age groups of men and women and ten nutrients recommended for each group. On the first revision in 1967, the fat allowance was presented at the ratio (12%) of fat calorie to total calories with no change in the number of age catagories and in the kinds of nutrients. And the basis of the riboflavin allowance was changed from the level of protein intake to that of energy intake. On the socond revision in 1975, there was brought 19 are catagories and ten nutrients recommended. On the third revision in 1980, age catagories increased to 22, and ten nutrients were recommended. On the fourth revision in 1985, there remained 21 groups by uniting the early and later periods of pregency. On the first revision in 1967, the recommended energy allowance was 3000 kcal, the highest level. Since then it has gradually been reduced. And it can be noticed that the protein allowance was high when food was difficult to obtain.

Objectives: The objective of this study was to analyse the methods being used to control food intake and physical activity in RCTs of human obesity. Methods: A total of 21 randomized controlled trials (RCTs) were investigated. Nine of which were domestic studies from "http://oasis.kiom.re.kr" and the other of which were foreign studies from systematic reviews of RCTs on herbal medicine for treatment of human obesity. Results: According to domestic studies, "low calorie diet" were recommended in five cases of the domestic studies, "maintain current dietary habit" were recommended in two and no information on diet was two. Considering the seven cases where the information on diet was available, patients' food intake were checked at every visit in six cases. Only two cases among the six had been dropped owing to the violation of dietary habit by patients. Exercises were prohibited in two cases, "maintain current level of phisical activity" were recommended in three cases and, from the rest, no information was available. The level of physical activity were not strictly controlled by any means hence no drop out. According to foreign studies, "low calorie diet" were recommended in two cases, "very low calorie diet (less than 700 kcal/day)" in one case, "maintain current dietary habit" in two cases, "do not eat fat" in two cases and no information was available in the rest five cases. Exercises which concerns spending about 300 kcal/day was recommended in one case, "moderate exercise" were recommended in three cases, "maintain current level of physical activity" were recommended in three cases and no information available in the rest five cases. Conclusions: In order to improve the accuracy of RCT, for the dietary side, researchers should record patient food intake at every visit by means of 24-hour dietary recall methods. This can be supplemented by multiple choice survey that are designed to help patients to diagnose themselves more accurately leading to less bias. For the exercise side, it is highly recommended to confine the exercises to walking only so as to quantify the amount of physical activity more easily by using pedometer.

An experiment was conducted to determine the effects of dietary supplementation of yeast Rhodotourula glutinis(Glutincus) on the performance and egg quality of layers. A total of 360 ISA Brown layers of 72 weeks old were assigned to one of the following 6 diets ：control, 25 ppm ${\beta}$-carotene. 0.5％, 1％, 2％ and 4％ Glutinicus supplemented diet. Each treatment was replicated three times with 20 birds housed in 2 birds cage units. Glutinicus supplemented at the level of 0.5％ significantly(p＜0.05) improved egg production and FCR. Soft and broken egge production rate decreased as the level of Glutinicus supplementation increased. Eggshell was highest in Glutinicus 4％ supplementation. Egg yolk color increased linearly as the level of Glutinicus supplementation increased up to 2％ of the diet. It was concluded that Glutinicus supplementation at the level of 0.5％ can be recommended for the improvement of egg production while 2.0％ can be recommended for egg yolk pigmentation.
