The purpose of this study was to analyze and evaluate dietary intake between with and without hypertension. Study subjects were more than 30 years old adults (n = 3,806) who participated in the 2001 Korea National Health and Nutrition Examination Survey. People who have 'self-recognition about hypertension' and 'having diet for hypertension' were excluded. Using the WHO standard, subjects were divided into the hypertensive group (SBP> 140, DBP> 90) and the normal group (SBP< 140, DBP< 90). The Body Mass Index (BMI) and the Waist-Hip Ratio (WHR) of a hypertensive group were higher than those of a normal group (p < 0.01). The distribution of the subjects for smoking, alcohol consumption, exercise, stress, preference of salty food were not significantly different between a normal group and a hypertensive group (p>0.05). Dietary intakes were investigated by the 24-hour recall method. When food and dish intakes analyzed by sociodemographic factors, normal group consumed more fruits than those of a hypertensive group. Statistical significant were shown at female group, residences in metropolitan area and having elementary school education (p<0.05). Hypertensive group consumed more alcoholic beverages than those of a normal group at 'age 39-39', 'aged 50-64', 'high economic status', 'low economic status' and 'residences in metropolitan' (p<0.05) The amount of intakes for fat, potassium, thiamin, vitamin C and alcohol were significantly different between the normal group and the hypertensive group (p<0.05). The highest score of the Dietary diversity score (DDS) was 4 in both normal group and hypertensive group. Normal group showed high Nutrition Density (ND) of vitamin C and hypertensive group showed high ND of sodium. In summary, these results showed that significant difference for people with hypertension were intakes of fruits, alcohol, thiamin, vitamin C. And these results differed by sociodemographic groups. Therefore, the differential approach in each group is demanded for prevention and control of the hypertension.

This is an analysis of the dietary behavior, nutrient intake status and INQ(Index of nutritional quality) of 129 college women according to their residences in the Daegu area. The average height and weight were 160.0 cm and 54.5 kg respectively. Diet intake data were obtained by using the 24-hour recall method to evaluate the usual diet of the subjects. The energy intake of the group, living alone was higher than that of living a roommate and living at home. Ca, Fe, Zn and folate intakes were low in all the groups. The composition rate of carbohydrate, protein and fat for energy intake was 58.9 : 15.5 : 25.6 in living alone, 59.9 : 15.1 : 25.0 in living with a roommate and 61.2 : 15.5 : 23.3 in living at home, compared with the preferred of 65 : 15 : 20. The group living alone showed significantly better mean adequacy ratio(MAR, 0.7) than the other groups (p<0.05). The group living with a roommate showed significantly better INQ in vitamin $B_6$ (p<0.01) and Fe (p<0.05) than the other groups did In conclusion, this study indicates that nutrient intake in college women in Daegu is considerably lower than the RDA values. Furthermore the group living alone showed better dietary behavior and nutrient intake status than the other groups. A nutrition education program for college women is necessary.

This study aimed to investigate the changed consciousness and expenditure on Kyong-Jo after IMF economic crisis and the some factors which have effects on the change. The expenditure on Kyong-Jo included donations and gifts associated with congratulations and condolences. The data were collected through the personal questionnaire on Cheju Island. The sample consisted of 400 married adults whose age were between 20 to 65. The independent variables were some individual characteristics, household related variables, and Kyong-Jo related variables. The dependent variables included the change in consciousness and expenditure on Kyong-Jo. The data were analyzed by methods such as frequencies, means, Multiple Regression and Logistic Regression analysis. Major results were as follows. The respondents perceived that Kyong-Jo is fundamentally a good custom to help each other when some one is in the hard time. Their perception of the expenditure on Kyong-Jo has not been changed even since IMF economic crisis. 70% of the respondents staid that there was little difference of the expenditure on Kyong-Jo before and after IMF economic crisis. This trend is in contrast to the perception and the expenditure of the people who lived in the other residences after IMF economic crisis. The factors which had significant effects on the respondent's consciousness of the expenditure on Kyong-Jo were occupation, whether owns a house or not, household income, and household assets. The change of household expenditure on Kyong-Jo was effected by the respondent's sex, occupation, household income, household assets, and social network. These results suggested that the respondents on Cheju Island more strongly hold the conservative perception to the expenditure on Kyong-Jo rather than the people in other residences.

The purpose of this study was to determine nitrogen dioxide(NO$_2$) decay rate by reaction between NO$_2$ and interior materials in Korean residence. The results of this research could be helpful to choose the interior construction materials and to study on reduction of indoor air pollutants. The results of this research are as follows; For 30 residences in Seoul and Incheon from October 2000 to march 2001, the mean of infiltration rate was 0.70$\pm$0.44 ACH, and single-detached houses (7 houses) and apartments (19 houses) were 0.97$\pm$0.55 ACH and 0.61$\pm$0.34 ACH, respectively. The $CO_2$ decay followed approximately first-order process ($R^2$=0.97$\pm$0.02). There existed a statistic significance in filtration rate between houses built in 1980’s and built in 1990’s by t-test (p<0.02). Mean of NO$_2$ decay rates in 26 residence3s except 4 residences was 0.94$\pm$0.49hr$^{-1}$ , and also 0.86$\pm$0.49hr$^{-1}$ , 0.97$\pm$0.50hr$^{-1}$ in single-detached houses and apartments, respectively. Mean NO$_2$ decay rates in houses built in 1980’s were 0.78$\pm$0.37hr$^{-1}$ , 1.33$\pm$1.03hr$^{-1}$ , respectively. Nothing were showed statistical significance among indoor temperature, indoor humidity, and NO$_2$ decay rate. However, NO$_2$ decay rates had a tendency to increase by increase of temperature and humidity. Average volume/surface of participated houses was 0.55$\pm$0.07m and mean NO$_2$ deposition velocity was calculated as 1.46$\pm$0.59msec$^{-1}$ .

We present a statistical model for the path loss of ultrawideband (UWB) channels in indoor environments. In contrast to our previously reported measurements, the data reported here are for a bandwidth of 6GHz rather than 1.25GHz; they encompass commercial buildings in addition to single-family homes (20 of each); and local spatial averaging is included. As before, the center frequency is 5.0GHz. Separate models are given for commercial and residential environments and, within each category, for lineof sight (LOS) and non-line-of-sight (NLS) paths. All four models have the same mathematical structure, differing only in their numerical parameters. The two new models (LOS and NLS) for residences closely match those derived from the previous measurements, thus affirming the stability of our path loss modeling. We find, also, that the path loss statistics for the two categories of buildings are quite similar.

The construction of settlement house in a permanent rental housing development area started between 1989 and 1992, planning of supplying two hundred fifty thousand residences, settlement house became compulsory as a welfare facilities. As a part of Welfare program for low income families, number of settlement housing increased dramatically, also domiciliary welfare center was beginning to set up as a branch of settlement housing to strengthen its service towards families and local communities, thus numerous social welfare organizations play a crucial part in resolving a welfare problem for low income families while satisfying local community's needs. However, despite of these efforts, the number if institutions cannot handle demand of local community's needs and number of welfare institution programs. as a solution, the alternation of space is being used, however, it did not solve basic problem, even worsen in terms of space efficiency.

The purpose of this study is to examine the changes of housing characteristics between dwellings occupied by two and more households and one household occupying dwellings over 10 years using the Population and Housing Censuses in 1985, 1990, and 1995. One dwelling for each household, referred to the ratio of the number of dwellings to the number of households, has been one of the most important housing goals in Korea. The results indicated that the ratio of dwellings occupied by one household as well as that of households occupying one dwelling by oneself have been increased since 1985. However, the number of dwellings occupied by two and more households have been decreased but the number of households who share one dwelling with other households have never been decreased. One dwelling for each household has been mainly increased by the multifamily attached dwellers in urban residences. Single-family dettached dwellings in the urban area are the most often shared with other households. Housing policymakers should consider not only the rapidly increasing single households but also renters shared one dwelling with others mostly homeowners of single-family dettached dwellings.
