This study is designed to explore the relationship between the level of housing satisfaction and housing values, as well as family characteristics and characteristics of residence. Questionnaires are administered to 526 adolescents from the four residential areas in Kwangju. Most of the adolescents are satisfied with their housing environment, especially indoors, however, they show a lower level of satisfaction toward the appearance and organization of the unit plan. It is found that the level of the safety, comfortability and social values predicted a meaningful variance in the level of housing satisfaction. Those with a higher degree of safety and social values tend to be associated with stronger housing satisfaction, whereas those with lower comfortability values are more associated with stronger housing satisfaction. Groups with higher household incomes are more likely to be satisfied with their housing environment. Groups living within a younger and larger house are more likely to be satisfied with their housing environment. Also, owners tend to show a stronger degree of housing satisfaction than renters.

This study attempted to identify relative evaluation to its attributes and improvement of consumer's demand in the Environment-Friendly Agricultural Products(EFAP). To identify the consumption patterns of EFAP, a series of household surveys were conducted for housewives residing in Seoul and its metropolitan area(Bundang and Ilsan). the sample size of the survey is 366 respectively. This study operated relative evaluation of EFAP by Multi-Demential Scales(MDS) about 10 attributes that this study set up. As the result, the consumers recognized that EFAP is "protection of ecosystem", "food safety", "good for growth of children", "high quality", and in case of conventional farming products is "inexpensive price", and "diversity of purchasing items". This trend has significant implications to the structure of EFAP output and how positioning strategies, and approaches should be properly formulated and implemented.

In order to evaluate landfill stabilization based on organic carbon, stoichiometric analysis and a biological methane potential (BMP) test based on modeling were performed at the 2^nd Sudokwon Landfill Site. Mass balance analysis through a BMP test proved to be more adaptable for evaluation, and it showed that 28.9% of landfill organic carbon was expected to remain by 2046, 30 years after landfill closure. The organic carbon ratio of total landfill waste for 2046 is forecasted as 2.9% in demolition waste and 5.1% in household waste, and, if one were to consider plastic as an organic waste, the ratios would increase to 15.9% and 28.3%, respectively. Therefore, it seems that organic matter biodegradation facilitating measures such as bioreactor landfill technology and preemptive recovery of combustible waste are necessary to shorten post closure management periods and to meet the landfill stabilization guidelines more safely.

Rapid industrialization has induced the migration of rural people to urban areas. Such migration has created enlarged the existing low income group. Residents of low income area have increased health risk owing to their poor living environment, low income. overwork and inappropriate health care. The general objective of this study was to group the pattern of medical care utilization of low income group. The specific objectives were to identify disease prevalence and medical care utilization of low income group. To meet the objectives of this study, household interview method was applied. A total of 1845 households in 5 areas such as Bongchon 5th Dong, Bongchon 2nd Dong, Sanggae 5th Dong, Sanggae 4th Dong, and Shinrim 7th Dong were visited and interviewed by field team during the period from April 19 to May 3. 1989. The major findings obtained from the information collected were as follows : The Number of room per household used was one to two rooms. The employment state of the head of household disclosed that 88.6% had a job and the remaining 11.4% were unemployed. The average monthly income was 502,770won. however, 30% of the total income was less than 300,000 won in Bongchon 5th dong area. and 34.5% in Shinrim 7th Dong area. 41.3% of households had debts, which was consisted of household expense(33.4%), income formulation(22.7%) and medical care cost(15.9%) etc. Prevalence rate of diseases during the preceding 30days before the date of the household interview was 387.7 per 1000 persons. The prevalence rate of female was higher than that of male. 8.9% of the sick persons wasn't receiving any medical treatment, and the main reasons of which were lack of economic availability(43.3%) and feeling of non treatment needed(33.7%). According to the study results it was found that the prevalence rate of chroic diseases and the disabled in low income resident areas was higher than that in the other areas. Therefore, the health status of this group should be improved through PHC approaches. In addition. in order to prevent the diseases and promote the health of those people, the health center as well as health subcenter should be strengthened.

Objectives: The purpose of this study was to examine the biochemical characteristics, intake of energy, and nutrients by household income levels of Korean adolescents aged 12 to 18 years. Methods: Data from the 6th (2013 ~ 2015) Korea National Health and Nutrition Examination Survey (KNHNES) were used for the study. A total of 1,839 (966 boys, 873 girls) subjects were included, and they were divided into four income groups according to their household income level. We examined general characteristics (gender, region of residence, skipping or not-skipping breakfast, lunch, dinner, frequency of eating-out), anthropometric characteristics (height, weight, weight status), biochemical characteristics (fasting plasma glucose, blood urea nitrogen, creatinine, triglycerides, cholesterol, HDL-cholesterol, hemoglobin, and hematocrit), the quantitative intake of energy and nutrients using the Korean Dietary Reference Intakes (KDRI), and the qualitative intake evaluated by the nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) of the four groups. Results: There were significant differences by income group within the region of residence and the rate of skipping breakfast, lunch, and dinner. The low-income group had a higher rate of skipping breakfast, lunch, and dinner. According to the income group, there was a difference in the height of boys, and there was no difference in the weight and obesity of boys and girls. In the biochemical characteristics, only the hematocrit of girls showed differences by income group. The quantitative intake of energy and nutrients compared with KDRI differed by income group. There were differences in energy, carbohydrates, proteins, thiamin, riboflavin, niacin, and phosphorus levels in boys and protein, vitamin A, niacin, and sodium levels in girls. The qualitative intake of energy and nutrients examined using NAR and MAR also differed according to the income group. The NAR showed differences in calcium in boys and vitamin C and calcium in girls. The MAR revealed differences in both boys and girls by income group. Conclusions: Among adolescents in the low-income group, the rate of skipping meals was high, and the quantitative and qualitative intake of energy and some nutrients was low. It is suggested that the nutritional intake can be improved by lowering the rate of skipping breakfast, lunch, dinner. We suggest that even just providing breakfast in schools can be considered highly effective in improving the rate of avoidance of skipping meals and improving nutrient intake. Also, we suggest that it is necessary to improve the food environment, food availability, and food accessibility through national and social support for low-household income adolescents.

Background: Despite the increasing role of dry forests in climate change adaptation and mitigation, these versatile resources has got less attention in the national and regional planning, their potential to enhance the local and national economy has been overlooked, and their contribution to sustainable environmental management has not been recognized. Hence, the objective of this study was to assess the socioeconomic contribution of dry forests and forest products to climate change adaptation in the Liben Woreda, Southern Oromia region of Ethiopia. Methods: For this study, an integrated qualitative and quantitative approach was used. A total of 74 households from villages in the Bulbul, Boba, and Melka-Guba kebeles were randomly selected for the household survey. Results: Results showed that 75% of the respondents in the area indicated that climate change has become their major sources of vulnerability, where drought has been manifested in the form of crops failure and massive death of livestock particularly cattle species. The main income strategies of the study households include livestock, crop, forests such as gum and resins, firewood and charcoal and non-farm activities such as in the form of petty trade, wage and aid. The average total household income was ETB 11,209.7. Out of this, dry forest income constituted 15% of the total income. In addition to using dry forests as rangeland for livestock, the communities collect wood for construction, fodder, traditional medicine, and forest food both for subsistence and for sale. On the other hand, dry forest products could be considered as less vulnerable, rather resilient livelihood strategies to climate- and environment-related risks compared to livestock and crop production such as in the face of drought periods. More than 48.6% of the households argued that the income generated from dry forests increased substantially due to increment in the level of engagement of family members in forest based income activities. On the other hand, 35.8% of the households responded that livestock production, particularly camels and goats, have been making the livelihood strategies of the respondents more resilient indicating the shift made from grazers browsers to livestock. In general trends show that, the trends of livelihood dependency on dry forest were highly increasing indicating the importance of dry forest income in responsse to frequent droughts. Conclusions: Dry forest income has been becoming crucial livelihood staretgy in response to frequent droughts in the study area and hence, it is important to improve the management of dry forests for livelihood enhancement, while also securing their long-term ecological functions.
