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.

This study reviewed the scoring system of th EPI to find out characteristics of seven non-residential buildings submitting the energy saving plan. And then 4 sectors was analyzed on architectural, mechanical, electrical and renewable energy aspects. The main results of this study are as follow. 1) All non-residential buildings were designed and applied on a similar level in more than half of all items. The characteristics difference was shown about 16∼23% of items by building use. 2) It was concluded that there are narrow variation in sum of average by building use and the more resonable result are derived when basic point of building use is applied one standard. It is determined that the criteria of basic point is the significant factor when the building uses are revised as basic point of building use is the most affecting item to the sum of EPI average.

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 purpose of this study was to evaluate the prevalence of obesity, dietary habits, and nutritional status by age among lowincome women, using data from the fourth Korea National Health and Nutrition Examination Survey (2007∼2009). Subjects were 8,356 women aged 20 and over. The subjects were classified into four groups by age. Dietary data from 24-hr recall methods were used to analyze nutritional status. The prevalence of obesity in the 50∼64 years age group was significantly higher than those of the other age groups. Among age groups, malnutrition was the highest in the 65-and-over age group. It appears that women in the 20∼29 and 65-and-over age groups were the highest nutritional risk. The percentage of carbohydrates in total energy intake was higher and the percentages of protein and fat were lower in the 65-and-over age group than other groups. Frequency of skipping breakfast was lower in women aged 65-and-over, and moderate physical activity significantly decreased with increasing age. Awareness of dietary guidelines was higher in women aged 30∼49 years than other groups, whereas it was lower in those aged 65-and-over years. Adherence to dietary guidelines of ‘eating a variety of foods from each food group’ was significantly lower in women aged 65-and-over years than those of other groups. However adherence to dietary guidelines of ‘eating breakfast everyday with a pleasant mind’ was significantly lower in women aged 20∼29 years than those of other groups. Therefore, this study shows that low income women have various nutritional problems by age group, and we should support a tailored approach to improve their nutritional status.
