This study is intended to look into parents' satisfaction of contracting-out system in employer-supported childcare centers. To achieve this, a survey was carried out to 400 parents who use national, public and private employer-supported childcare centers. The results were as follows. First, employer-supported childcare factors were the qualities of childcare environment, childcare program and early childhood teacher in both contracted-out and in-house services. The satisfaction with facility, program, operation and childcare training was improved in good employer-supported childcare factors And the satisfaction with the relationship between these factors could improve the expectation for the use of employer-supported childcare centers. Second, the difference in the operation of employer-supported childcare centers showed that the most preferred size was 50 to 74 children. The contracted-out services was more preferred than in-house services. And the location of on-the-job facility was more preferred than off-the-job facility. As stated above, the preference of employer-supported childcare centers was more raised than that of general kindergartens or childcare centers by an increase in the trend of working child parents' dual income. In other words, small and medium sized childcare centers of some 50 children were more preferred than large scaled childcare centers. Consequently, the retainment of childcare programs, facilities and quality teachers contracted out to professional childcare centers can improve the satisfaction with them.

This study was performed to establish the discrimination of the corpus albicans that were formed after normal parturition and abortion in Holstein, The corpus albicans were obtained from 504 cows and 506 heifers slaughtered in the Agricultural Cooperative's Livestock Products Joint Market of Seoul City from March 2007 to October 2007. The difference in a gross examination (morphology, fibrogenesis, deposit state, color, and size) among the fixtures that exist in their ovaries was investigated. All of the cows had corpus albicans in their ovaries: 423 cows (83.9%) had less than three corpus albicans, 81 (16.1%) had more than four. In the heifers, however, 463 (91.05%) had no corpus albicans, 39 (7.7%) had one, and four (0.8%) had more than two. In the types of corpus albicans 73.2% of the cows had oval-type, 14.4% had circular-shaped, 12.4% had irregular-type. In the aborted heifers, however, oval-type appeared in 88.6% and circular-shaped appeared in 11.4%, and no irregular-type was found. There was no significant difference in the fibrogenesis and size of corpus albicans between cows and aborted heifers. However, slight difference in the color of the corpus albicans was observed between two types. In conclusion, it is not easy to discriminate by gross examination of ovary between cows and aborted heifers in the slaughter house.

The purpose of this study was to suggest an educational direction to aid in formulating a dietary life that is suited to Korea's multicultural families. This was achieved by analyzing the dietary life of immigrant women from multicultural families in Daegu. The study was carried out with 94 immigrant women form multicultural families who were served by public health center A (20 women), public health center B (47 women) and public health center C (27 women). Their home countries were China (55.3%), Vietnam (37.2%), Philippines (3.2%), Japan (2.1%), Uzbekistan (1.1%) and Thailand (1.1%). When the scores of their dietary balance were compared on the basis of the time they have been in Korea (Less than 1 year, 1~3 years, more than 3 years), we found that the score of immigrant women who stayed for less than 1 year was higher than those who stayed for more than 3 years (p<0.05) in terms of their intake of meats, fishes, potato, calcium, and carbohydrate. When subjects were asked about Korean food they wanted to learn how to cook, 30 different types of food were selected and 95.5% of the respondents wanted to learn in detail how to cook Korean food. The place most suitable for them to learn cooking was college (30.3%), while the house of their husband (2.2%) was lowest. Therefore, it seems that a college, public health center or welfare center are good places for immigrant women from multicultural families to participate in an education program that is designed to teach them how to cook Korean food.

Recently, new detached houses on a small plot in low-rise residential urban area have attracted more public interests than ever before. This study aims to categorize basic types of interior plans in small urban detached houses by analyzing the layouts of the public space(LDK) within them which are popular in Japan. The results of this study may be summarized as follows. Unit floor plans were basically classified as 16 types according to the layout of LDK. Among these, the LDK type in a straight line shows the most at 28.9%. Again, these plans were sub-classified into 38 types by plan composition. The new 'LDKL' (a new term the authors propose to be used) type was observed in cases where K was directly connected to L. This type appears at 9 out of 38 types. In the connection of LDK, the LDK type shows the most at 60.8%; secondly the L-DK type at 29.9%; thereafter the LD-K type at 6.2%; and lastly L-D-K type, the least frequently at 1.0%. The cases of inter-level connection between LDK and the surrounding space were observed in various cases such as the open workplace of the upstairs hallway visually connected with LDK through the void space and as the attic space of the pitched roof visually linked to it.

The repair and maintenance cost of domestic public rental housing is an issue of considerable interest and growing financial concern. This paper suggests a quantity-based model as an alternative method for predicting costs, instead of the conventional model which is based on actual cost data. Furthermore, this paper provides a forecast of the repair costs incurred each year during the multi family house's maintenance phase (40 years). The recently changed the long-term repair plan and quality-improved interior materials were considered into the research. In order to estimate the cost of maintenance work, 5 sample apartments were selected and analyzed. The repair and maintenance cost from the case studies was converted to cost per household and per floor area for general use. On the other hand, the net present value method was applied to reflect the effect of time. We expect that the results will help to establish expenditure plans that are more effective for public rental housing in the maintenance stage.

The purpose of this study is to develop neighborhood assessment tools from the perspective of women in order to evaluate neighborhood environments and suggest better policies and planning practices for women-friendly neighborhood environments. To do so, we analyze correlations between women's quality of life and the neighborhood environment. Specifically, we gave female participants a mapping survey, interview, and questionnaire to collect data targeting women living in Onyang 2-dong and 5-dong in Asan city. First, we developed a neighborhood assessment tool derived from an extensive literature review and particular case studies. The mapping and interview surveys indicated that specific aspects neighborhood life needed to be improved in a similar area. In particular, women complained about Onyangoncheon station, a commercial area, and detached house area. Second, analysis of the neighborhood environmental factors affecting women's neighborhood satisfaction, crime safety, traffic and walking environment, accessibility of living facilities, green and public spaces and childcare environment were statistically significant. Of these, the inclusion of green and public spaces was the most influential factor. Third, the neighborhood environmental factors affecting women's neighborhood attachment, crime safety, traffic and walking environment, accessibility of living facilities, green and public spaces and childcare environment were statistically significant. Of these, accessibility of living facilities appeared to be the most influential factor. Fourth, the neighborhood environmental factors affecting women's housing mobility decisions, crime safety, traffic and walking environment, accessibility of living facilities, green and public spaces and childcare environment were statistically significant. Of these, childcare environment was the most influential factor.

The recently introduced public rental housing REITs was just different the business structure from the existing public rental housing system and the basic supply system is the same. So the ownership conversion for public house over 10 years rental duration is possible after half of the obligated rental duration according to the agreement between lessor and lessee. However rental business operators are likely to have a negative attitude to the early ownership conversion because of less expected profit. Thus, there is a need for an analysis of proper early ownership conversion moment that can achieve public purposes while ensuring the profitability of public rental housing REITs. In this study, the characteristics of the ownership conversion rights that can lessee to exercise considered to be options. Also the nature of 'REITs', 'public rental housing REITs' is considered to be affected by the macroeconomic variables. Thus, this study analyzed the value for ownership conversion in the public rental housing REITs according to real option scenarios reflecting macroeconomic variables. As a result, according to the change of the variation rate of the macroeconomic variables, it was found that with adjustable early ownership conversion time using the DCF(Discounted Cash Flow) model. Therefore, it is possible to ensure profitability of early ownership conversion by predicting the variation of variables.

The drinking water in the apartment is stored in reservior tank and thereafter supplied each household. In case the drinking water is stored too long or insanitary, tap water might change in quality. This study was carried out to evaluate the physico-chemical and microbiological conditions of 36 samples of tap water of apartments compared to 18 samples of tap water of independence houses in Taegu City from May to October, 1987. Main findings are summarized as follows : PH values were within normal range in all samples. Samples less than 0.2ppm in residual chlorine accounted for 16.7% in the appartment and 5.6% in the independence house. Nitrite nitrogen was detected 2.8% of apartment samples only. Among the total of 54 samples, 11.1% of the apartment and independence samples were over the normal value in standard plate count. Samples more than 1.8 of most probable number(MPN) accounted for 27.8% in the apartment and 33.3% in the independence house. In result of test for residual chlorine, nitrite nitrogen, standard plate count, and MPN, the proportion of the samples revealed inappropriated in respect of drinking water standards. In case of all sorts of tests was 2.7% in apartment and nothing in independence houses, in case of 3 sorts of tests was 2.7% in apartment and 5.6% in independence houses, in case of 2 sorts of tests was 8.3% in apartment and 5.6% in independence houses, and in case of only 1 test was 25.0% in apartment and 22.2% in independence houses. Correlation between residual chlorine and standard plate count, and between standard plate count and MPN were observed. It was found that the more years since construction of apartment were, the worse tap water was in quality.
