The study was first part of the research on development of consumer education program as social education program. The purpose of this study was to review social consumer education programs conducted by various organizations and to examine the consulting statistics from Korea Consumer Protection Board and Korea National Council of Consumer Organizations. In Consumer Protection Board, consumer education was operated mainly for both college students majored in consumer studies and public-sector workers. Outgoing education was provided mainly to the persons in industries and housewives. Other consumer organizations conducted consumer education using government funds. The organizations considered 'purchasing' and 'consumerism' most frequently as the topics for the education. 'Credit' and 'insurance' were another main concerns at the education. The consulting statistics showed that 'mobile communication', 'laundry service', 'health foods', and 'educational materials for foreign language' took the largest portion of the consumer consulting. Some implications were made for developing consumer education program as social education.

We propose an alternative procedure to select penalty parameter in $L_1$ penalized robust regression. This procedure is based on marginalization of prior distribution over the penalty parameter. Thus, resulting objective function does not include the penalty parameter due to marginalizing it out. In addition, its estimating algorithm automatically chooses a penalty parameter using the previous estimate of regression coefficients. The proposed approach bypasses cross validation as well as saves computing time. Variable-wise penalization also performs best in prediction and variable selection perspectives. Numerical studies using simulation data demonstrate the performance of our proposals. The proposed methods are applied to Boston housing data. Through simulation study and real data application we demonstrate that our proposals are competitive to or much better than cross-validation in prediction, variable selection, and computing time perspectives.

Recently, Korea suffered serious social conflicts between generations due to population aging. Anxiety about depletion of the National Pension Fund is one of the social problem to young generation, because of the uncertainty that they will not able to receive the pension they paid. At the same time, due to the high housing rent in Seoul metropolitan area, the demand for housing welfare and supply of public rental housing for young generation was increased. There are some opinions about using National Pension Fund to supplying public rental houses in the society. In this research, we were concentrated on finding the suitable areas for the public rental house using National Pension Fund. First, verifying the validity of the investment using National Pension Fund for the public rental housing was done. And spatial statistical methods were applied to explore the suitable areas for the public rental housing in Seoul metro area. Finally, this study divided young people into three groups and analyzed ways to supply public rental housing for each group in proper areas by their demand. This research's ultimate goals are mitigating the conflicts between the generations and achieving both profitability and publicness of National Pension Fund.

This study examined the changes of depression and life satisfaction among the elderly living together in group-home and congregate housing. And in this course, it was to verify the practical effects of the recent government and local authority community life of elderly people by comparing them with the groups of elders living alone. The study was divided into Time 1 and Time 2, and 205 person's data were used for the final analysis. PASW Statistics 18.0 was utilized to analysis the data of this study, because it is difficult to explain the results of this analysis, secondary qualitative research has been used to identify additional contextual information. The major results of this study are as follows. First, the depression of the subjects was significantly improved in the case of living in group-home and congregate housing, and it was significantly worse in the group of elders living alone. Second, the life satisfaction of survey subjects was significantly improved when living in congregate housing, group-home was significantly worse, and the group of elders living alone were not statistically significant but slightly worse. Third, mixed research methods were applied to make accurate interpretation of changes of life satisfaction of the elderly living in group-home. Based on the results of this study, it is possible to establish appropriate measures for the elderly to improve early adjustment and quality of life in community life. And the community life of the elderly can contribute to a real social safety net by solving the blind spot of welfare. At the national level, it can be utilized as a standard reference to improve and strengthen existing policies by providing data that can simultaneously examine the performances and problems of various policies related to housing or the welfare of the elderly.

This study aims to identify the characteristics of the cancelled districts of housing redevelopment and housing reconstruction project. The subject of this study is 189 project districts(121 promoted districts, 68 cancelled districts). Both 121 promoted districts and 68 cancelled districts were analyzed by Decision Tree Analysis. The first separation of the release zone influencing factors was made by the Development Actors. In other words, the most important independent variable for determining the release zone influence factor was shown to be the presence or absence of propulsion actors. Of the 89 districts without propellers, 41 were lifted and 48 were promoted, and 9 out of 100 districts with propellers were lifted and 91 were promoted. The second separation of the impact factors on the zone was then made by Land Owners, and the probability of cancellation increased if the number of landowners was less than 468 and 37 out of 62 were removed. On the other hand, four out of 27 districts with more than 468 landowners were lifted and 23 districts were promoted. The third separation was made by the Average Land Assessment, and 35 zones were lifted below the standard of KRW 269.64 million/m² approximately KRW 8.91 million per pyeong, and two zones were lifted at higher official prices. In the second division, the number of landowners was 468 or more, and in node4, four areas were removed from areas with a public land area ratio of 29.43% or more, and no areas less were released. This study used SPSS Statistics 26 S/W for analysis.

Oriented Strand Board (OSB) is an important engineered wood product used in housing construction which has a lower environmental impact or "carbon footprint." In this paper, reliability and statistical tools are applied to gain insights on the strand thickness of OSB panels. An OSB panel consists of several hundred wood strands that are resinated and pressed. The variability of OSB strand thickness for six manufacturers in the Eastern United States is examined as a whole, as well as individually. Little research exists on OSB strand thickness across mills even though strand thickness variability has been documented in laboratory experiments to greatly influence the dimensional stability of OSB panels. Our aims are to quantify and characterize strand thickness, plus apply reliability techniques, such as Kaplan-Meier curves, to characterize the probability of strand thickness. We further explore graphically and statistically the thickness of the strands.

This study aims to find out the cause of delay by analyzing the process of 12 Core-based Improvement pilot projects, especially focused on lands, buildings, population status. For this purpose, it performed a literature research on maintenance plan reports, various statistics of building and population status analysis, a field research and an individual interview with public officials in charge at local governments of 12 project districts. The findings are as follows; 1) it was difficult to cope flexibly to environmental changes because the core sector was so large that the plan was led to areal improvement. 2) the project was selected without reflecting the characteristics of the core sector and the area of residents-led renovation properly in terms of building status such as building density and old buildings ratio, 3) the coordinator group for socially disadvantaged class in the district was not operated and thus foundation for residents-led renovation was not set up. In conclusion, it should be presented the proper size of the core sector when the core-based residential environment improvement project is initiated in the future. In addition, building status is taken into consideration when designating the core sector and the area of residents-led renovation. The coordinator group needs to be operated from the early stage of the project as well.

Industrialization and Urbanization caused a great influx of rural population into the cities, which caused housing types to change from detached homes to more apartments homes. The official 2014's Statistics (http://kossir.kr) show that half (49.6%) of the Korean population live in apartment buildings and 37.5% live in detached houses. For this reason, the apartments have become the typical housing in Korea. So, the aim of this study is to compare and analyze the internal apartment space of Budang (New-Town) and Wirye (New-Town), since these Budang apartments are the first new-town housing and Wirye apartments are the last new-town housing in Korea. I have used the Convex Analysis of Space Syntax Program in analyzing the inside space of both of these locations' apartments. The results are as follows : First, the inside space of Wirye apartments have more convex space than that of the Budang apartments. Second, the common inside space of the Budang apartments were planned by integration space, on the other hand the inside space of Wirye apartments were planned by segregation space. Third, the master bedroom in both of the locations' apartments were analyzed for their strong integration space which they may have in common. The K (Kitchen) + D (Dining) space in Budang apartments are classified as integration space, on the other hand L (Living) + K + D space is also classified as integration space. The L+K+D space of the Wirye apartments is classified as integration space. Finally, the inside space of the Wirye apartments were planned more for various spaces than that of Budang apartments. The concept of master bedroom in both new-town was not planed for a couple privacy space but the heart of the family.

End-uses of household water have been influenced by a housing type, life style and housing area which are considered as internal factors. Also, there are external factors such as water rate, weather and water supply facilities. Analysis of influential factors on water consumption in households would give an explanation on the cause of changing trends and would help predicting the water demand of end-use in household. In this paper, we used real data to predict toilet and laundry water-uses and utilized the linear regression model with autoregressive errors. The results showed that the monthly autoregressive error models explained about 71% for describing the water demand of end-use in toilet and laundry water-uses.

As environmental sustainability becomes a key consideration in policy-making, more responsible consumption and utilization in daily life concern both health and quality of life. To address inequities in health in relation to environments, waste management has taken more progressive ways, and one of them is biomass-to-energy conversion that utilizes energy recovery from food waste. By extension, a food waste zero-emission system using fermentation and extinction technology gains much attention, so that this study is designed to examine residents' attitudes toward recycling food waste produced at home and toward food waste zero-emission system. Utilizing a survey questionnaire, this research collected data from 400 individual units of multifamily housing estates nationwide, and the data were analyzed using descriptive and inferential statistics. The findings indicate that food waste generated at home was highly water-contained and produced in the stage of food preparation before cooking while respondents viewed that food waste collection and treatment needed to be improved. It's noted that respondents strongly supported the use of food waste as a energy source and would have the use of the food waste zero-emission system built in kitchen sink. Regression analysis showed that educational attainment of housewives, cooking style, and planning food purchase were statistically significant factors in the attitude of the responded residents toward recycling food waste while none of the factors were in the attitude toward the food waste zero-emission system.
