With rapid urbanization, various problems have been occurred in the city. The most serious one is dwelling. The gap of income between the rich and the poor resulted in deteriorating the pattern of the house consume. In case of developing a bad residential area, this area is changed into a new residential area, but the dweller, who lived in the bad area, may move into the outskirts of the city. This means that a bad residential area is sprawled and spreading. Therefore. the rescue plan of the existing dweller according to urban redevelopment were suggested in this study.

This study covers museum rest areas among the methods that reduce museum fatigue. The subjects of the study were Seoul branch of the representative National Museum of Contemporary Art and National Museum of Korea. These museums were compared and analyzed with The National Art Center of Tokyo and Tokyo National Museum. The first research step was the analysis of museums' floor plan, and the second step was the tracing survey of visitors' movement. The result of this study was as follows. The National Art Center of Tokyo and Tokyo National Museum had the rest space within the visitors' route along with good viewing areas. National Museum of Korea had poor viewing area even though there was the rest space withing the visitors' route. Lastly, Seoul branch of National Museum of Contemporary Art had the rest space out of visitors' route along with poor viewing areas. This study is meaningful in that it provided guidelines for museum space plan with visitors' route considered, so that their museum fatigue can be relieved along with the guideline that can be applied to space elements of rest space.

A series of experiments were carried out for two successive years to investigate the productivity of forage turnip in mid-northern area of Korea. Fresh matter and dry matter yields of 6 foreign cultivars (Purple Top Strap Leaved, Purple Top White Globed, Seven Top, Shogoin, White Egg and Amber Globe) seeded either in early spring or in autumn after harvesting forage corn were evaluated with different seeding date and harvesting date as well as with different level of fertilization. The results obtained are summarized as follows: 1. The earlier the seeding date in spring (Mar. 29, Apr. 12, Apr. 16) was, the higher was the yield of fresh matter and dry matter as the plant growth ceased after mid June, when the temperature began to rise. 2. In spite of its high DM yield, the Japanese cultivar, Shogoin, showed poor forage quality for summer feeding due to its earlier bolting in harvesting season. 3. Of the 6 cultivars Purple Top White Globed showed highest DM yield (800 kg/ 10a) in mid area including SEOUL irrespective of planting season. 4. Although the turnips showed mostly positive yield responses to fertization, the differences were not great especially above the level of$N-P_2O_5-K_2O$: 5-3-4 kg/lOa. 5. IN TAEGWALLYONG, a northern area of Korea, the average fresh matter yield of the six cultivars tested amounted to 3,500 kg/lOa when drilled on June 30 and harvested on Aug. 30, although bulb formation during the summer was relatively poor. 6. Concluded, forage turnip is regarded to be a suitable catch-crop which has the potential to maintain and increase the total forage production in mid-northern area of Korea. The intercropping is recommendable especially for autumn planting well past the time forage corn has been harvested.

The community structure and health status of macrobenthos assemblages were investigated in the subtidal area of the Nakdong River estuary, Southern Coast of Korea. Benthic fauna samples were collected seasonally at 8 stations in the subtidal area of the Nakdong River estuary from February 2013 to October 2015. During the survey, a total of 380 species and 4,603 ind./m² of macrobenthos in all sampling areas were collected. The major dominant species were the polychaetes Minuspio japonica, Pseudopolydora kempi, Heteromastus filifomis, Capitella capitata, the amphipod Grandidierella japonica and the bivalvia Arcuatula senhousia. Some species of polychaetes found in the study area consisted of opportunistic species that showed high densities when habitat condition was poor. On the other hand, macrobenthos assemblages in the study area were divided into brackish water and marine groups. Abundance was high in the brackish group, while the number of species and diversity index were high in the oceanic group. The three indices (AMBI, M-AMBI, and BHI) in the assessment of health levels based on the ecological characteristics and number of species in macrobenthic were commonly shown to be in good condition in the group of oceanic stations, while relatively poor conditions were reflected in the group of brackish stations. Compared to other indices, the M-AMBI index of the three indices for health assessment was considered to be a relatively more suitable one to assess benthic ecological conditions.

Objectives: The purpose of this study was to identify the stages of change distributions for nine major health behaviors among poor children in underserved area, and to provide basic information for developing specific objectives and strategies for health education program. Methods: The health behavior data were obtained with a self-administered questionnaire and analysed for 3,081 poor children in 106 local children's centers nationwide. Stages of change classification were based on self-reported responses to five statements. The health behaviors included were balanced diet, safety behavior (helmet and protective device use while riding), regular exercise, smoking, alcohol use, drug use, sleep pattern, weight management and stress management. Results: Poor children were more likely in precontemplation and less frequently in action and maintenance stages for a safety behavior. 33.1% of respondents were precontemplators, 29.9% contemplators, and 6.5% in preparation stage. Only 4.3% and 9.6% were in action and maintenance stages, respectively. Gender differences were apparent. Boys were more likely to be precontemplators for nine health behaviors. Children from the lowest socioeconomic status and disrupted family were more likely to be in precontemplation for weight management and exercise behaviors. Children living with both parents were more likely to be in the action and maintenance stages for nine health behaviors. Stages of change for balanced diet and smoking were significantly related with those for other eight health behaviors. And the stage of exercise adoption was found to be significantly related with those for other seven health behaviors. Conclusion: Safety education must receive high priority in health education program for low income children. Balanced diet smoking cessation and regular exercise could be a possible gateway behavior toward healthier lifestyle practices.

Background The scar alopecia after cranioplasty (SAC) may decrease the patient's quality of life. We have treated SAC using follicular unit extraction (FUE). The aim of this study was to discuss that efficacy of FUE and how much hair follicular unit (FU) should be transplanted intraoperatively for the treatment of SAC. Methods We treated 10 patients (4 men and 6 women) who had SAC using FUE. Results The average age, alopecia size, and intraoperative hair density on the graft area were 29.8 ± 12.1 years, 29.8 ± 44.5 cm², and 34.6 ± 11.8 FU/cm², respectively. One year postoperatively, the average hair survival rate on the graft area was 66.3 ± 6.1%. Hair appearance was rated as good in six, fair in three, and poor in one. Among patients whose 1-year postoperative hair density was ≥ 20 FU/cm², five of six patients achieved good results. However, among patients whose 1-year postoperative hair density was < 20 FU/cm², all four patients achieved fair or poor results. The postoperative hair density was significantly higher in patients whose 1-year postoperative hair density was ≥ 20 FU/cm² than in patients whose 1-year postoperative hair density was< 20 FU/cm². The rate of achieving fair or poor results was significantly higher if the postoperative hair density was < 20 FU/cm² than if it was ≥ 20 FU/cm² (p = 0.047). Conclusions FU excision is useful for the treatment of scar alopecia after craniotomy. Our results suggest that the 1-year postoperative hair density should exceed 20 FU/cm² to achieve good outcomes.

Purpose: This study aims to map the spatial distribution of poverty using nighttime light satellite images as a proxy indicator of economic activities and infrastructure distribution in D.I Yogyakarta, Indonesia. Research design, data, and methodology: This study uses official poverty statistics (National Socio-economic Survey (SUSENAS) and Poverty Database 2015) to compare satellite imagery's ability to identify poor urban areas in D.I Yogyakarta. National Socioeconomic Survey (SUSENAS), as poverty statistics at the macro level, uses expenditure to determine the poor in a region. Poverty Database 2015 (BDT 2015), as poverty statistics at the micro-level, uses asset ownership to determine the poor population in an area. Pearson correlation is used to identify the correlation among variables and construct a Support Vector Regression (SVR) model to estimate the poverty level at a granular level of 1 km x 1 km. Results: It is found that macro poverty level and moderate annual nighttime light intensity have a Pearson correlation of 74 percent. It is more significant than micro poverty, with the Pearson correlation being 49 percent in 2015. The SVR prediction model can achieve the root mean squared error (RMSE) of up to 8.48 percent on SUSENAS 2020 poverty data.Conclusion: Nighttime light satellite imagery data has potential benefits as alternative data to support regional poverty mapping, especially in urban areas. Using satellite imagery data is better at predicting regional poverty based on expenditure than asset ownership at the micro-level. Light intensity at night can better describe the use of electricity consumption for economic activities at night, which is captured in spending on electricity financing compared to asset ownership.

The purpose of this study was to examine the eating habits and nutrient intake of industrial workers who work day and night shifts. In the area of percentage of skipped meals, the day shift workers responded that they usually skipped breakfast and the night shift workers often skipped lunch and dinner. The day shift workers answered that they skipped meals because of lack of time. The night shift workers cited poor appetite as their main reason for skipping meals. The intake of calories, Vitamin $B_2$ and calcium of the industrial workers who worked day and night shift was lower than the Korean RDA. The intake of iron of the male night shift workers was lower than the Korean RDA The intake of calories, protein, calcium, iron, Vitamin $B_2$and niacin, vitamin C of the female night shift workers was lower than the Korean RDA. In the area of nutrient intake, the night shift workers both male and female got lower scales than the day shift workers. The nutrient intake of the female night shift workers was the worst. Because they cook for themselves and live alone, their nutrient intake and eating habits were bad. The night shift workers were worse than the day shift workers and the female night shift workers were the worst. Considering the above results, night shift workers should correct their poor eating habits, their nutrient intake and have a well-balanced diet.
