The purpose of this study was to evaluate dietary habit and nutritional status by household income in female adults, using data from the $4^{th}$ Korea National Health and Nutrition Examination Survey (2007~2009). Subjects were 8,356 women over the age of 20 years. The subjects were classified into 4 groups by household income level. Dietary data from 24 hr recall methods were used to analyze nutritional status. The obesity rate of the low income group was significantly higher than the rates of other income groups. Additionally, the nutritional status of the low income group was worse than those of other groups. The percentage of carbohydrate in total energy intake was higher and food security status was lower in the low income group than in other groups. Awareness and adherence to dietary guidelines were also lower in the low income group. Adherence to a dietary guideline of 'avoiding salty foods and trying to eat foods with bland taste' and 'eating a variety of foods from each food group' were lower than those of other groups. However, the frequency of skipping breakfast among the low income group was lower than that of others. Therefore, this study suggested that low income women should decrease the percentage of carbohydrate in total energy intake and adhere to dietary guidelines, especially those of avoiding salty foods and eating a variety of food groups, in order to improve their nutritional status.

According as the economy develops and the level of living quality rises, a large enclosure buildings such as the center of a large-scale international conferences, exhibitions, a large sports facilities are increasing in domestic as well as advanced countries. This large enclosure buildings have generally large space volume and a high density of occupancy per unit floor area compared to other buildings. Especially, it has the feature that the thermal environment has big difference horizontally as well as vertically and living spaces are restricted within nearby floor area. Also, this spaces have special thermal characters and airflow mechanism each other. CFD simulation can analyze the various thermal characters of large enclosure buildings exactly. The merit of simulation is that it can minimize the error in planning step by analyzing various airflow and thermal character in advance when the air conditioning works. Recently, the use of the under floor supply air conditioning system are increasing. This system air conditions not total space but the living space nearby the floor is by installing inlet on floor or under the seats. This study aimed at predictive evaluation of thermal environment in a large-scale auditorium appling the under floor supply air conditioning system by using CFD simulation. From thermal environment point of view in the residential field, the results of this study are as follows; 1) In cooling condition, all CASEs satisfy allowable supply air velocity 0.35m/s and CASE 2 and CASE 5 at which supply air temperature is about 20℃ are suitable condition. 2) In heating condition, all CASEs satisfy allowable supply air velocity 0.5m/s and CASE 7 and CASE 9 at which supply air temperature is about 22℃ are suitable condition.

The grandmother role may be an important support network for dual-earner families and become more saliency among those children who are living with their grandmothers than those who are not. The purpose of the present study was to investigate the effects of family structure characteristics on children`s solidarity with their grandmothers and grandmothers` effects on grandchildren`s self-esteem. Questionnaire data were collected from 429 grandchildren in the fifth and sixth grades. The major findings showed that (1)Solidarity between grandmother and grandchild in dual-earner families was associated with living arrangement. (2)Children`s self-esteem in dual-earner families was not related to living arrangements with their grandmother. (3)Factors predicting solidarity between grandmother and grandchild and the grandchild`s self-esteem differed by living arrangement. Solidarity between grandmother and grandchild was explained by grandmother-mother relationships, health of grandmother, parent-children relationship and occupational status of father for children living with their grandmothers. For those children not living with their grandmothers, grandmother-mother relationship, the educational level of father, families` economic level, parent-child relationship and health of the grandmother were significant predictors of grandmother-grandchild solidarity. (4)The regression of predictor variables on self-esteem for children living with grandmother revealed that grandmother-grandchild solidarity was the most powerful predictor, followed by occupational status of father, the educational level of mother, economic status of the family and parent-child relationship. For those children who were not living with grandmothers, parent-child relationship, economic status of the family, grandmother-grandchild solidarity and the educational level of the mother were also significant factors in that order.

Objectives: Since most oral diseases are not life threatening, it can be assumed that an individual`s behavior to maintain one`s oral health is most likely influenced by one`s oral health knowledge. Methods: Mothers whose children are attending five kindergartens and child care facilities in the city of Danjin, Chungnam were selected as subjects of this study. Out of a total of 230 questionnaires collected. A self-administered survey was conducted from April 1 to April 30, 2012. The data were analyzed using SPSS 19.0 (SPSS 19.0 K for window, SPSS Inc, USA) with the level of significance as 0.05. Results: 1. Most of the participants correctly answered questions on the oral health knowledge with a mean of 7.37 out of 9. 2. In the section of caring a child`s oral health behavior, ``caring a child to brush his or her teeth three times a day`` had the highest score of 3.45 out of 5. 3. Looking at caring a child`s oral health behavior and a mother`s oral health knowledge by general characteristics of mothers, there were no significant differences based on the mother`s age, whether a mother is currently working or not, her level of education, and her monthly average income. Conclusions: Based on the above results, we can draw a conclusion that the lower the difference between the rate of correct answers and that of incorrect answers on mother`s oral health knowledge to her child, the higher the mother`s score of caring her child`s oral health behavior, leading to better caring.
