In this study, we analyzed the electric vehicle (EV) purchasing behavior with market segmentation in Seoul using the binary logit model. For the model estimation, the experimental design of SP survey generated 24 scenarios with purchase price, charging station availability, and driving range of EVs. The results of market segmentation analysis indicated that the owners of subcompact and compact size cars were primarily affected by the purchasing price while those of mid and full size cars were more sensitive to the charging station availability. By housing type, the charging station availability was the most important factor for the residents of apartment while the purchase price was the most important factor to choose the EVs. These results presented that the EV supply strategy of the automobile manufacturer should be diversified according to the marketing target and the expansion of the public charging infrastructure should be the top priority in the government policy.

The channel improvement plan has contributed to the flood damage reduction studies and the plan has mainly performed by the levee construction which creates the cut river. The cut river has mainly used as the agricultural and housing purposes. Recently, however, it is considered as a natural wetland for the purposes of a flood control and preservation of nature. So, this study compares the economical benefits according to the purposes of the cut river utilizations such as an agricultural, levee construction for flood damage reduction, and wetland. The study area is the downstream part of Kok-Neung stream which is a main tributary of Han river. The agricultural and levee construction benefits are estimated based on the 'Agricultural and Forestry Statistical Year' (2000) and the 'Standard for River Design' (2001). The benefit or value for the wetland utilization of the cut river is estimated by the enquete using questionnaire. As a results, for the case of which the cut river is used as an agricultural land, the present net benefit is estimated as 195.81 million won, for the levee construction, as 20853.00 million won and for the wetland, as 24692.89 million won. Therefore, the wetland is the best choice for the cut river utilization.

The present study was intended to investigate ecological characteristics of poverty areas in Seoul from the perspectives of children's development. More specifically, the objectives of the study are to examine environmental ecology of the poverty areas and it's potential psycho-social development of children. Three poverty areas and 150 children currently living in the are as were sampled ; 70 children from middle class families and 88 from lower class respectively. Focal ecological aspects surveyed family environment, outdoor play ground and facilities, and village housing structures. Psycho-social dimension's development dealt with in the study included children's perceptions of parental child rearing practices and role taking, and children's future perception and perspectives. Data were collected through interviews and observations using structured formats. Following results were obtained from the data : 1. Children from the poverty families showed a higher tendency to have working mothers than those from middle class. 2. The rate of having single room is higher for children from middle class by two times than from lower class. 3. Children from lower class tended to have less favorable perceptions of attitudes tote and their own families than those from middle class. 4. The likelihood of showing discrepancy in vocational choice for children between parents and children is higher for children from lower class and those from middle class. 5. Children from lower class tended to allot more time in playing with peers than those from middle class. 6. The size of outdoor play ground are inadequately poor both for middle and lower class children. The inadequateness is particularly severe for the lower class children, showing that the size and facilities of playing ground available for the child from lower class is less than half compared with those of the children from middle class.

The purpose of this study is to deduce dwelling selection criterion and to consider change of values and consciousness of dwelling on people who return to farming & going to village. For that, questionnaire of evaluation of housing choice is conducted by people who return to farming & going to village in Jellanam-do by the AHP. The results are as follows. First, four factors as the primary hierarchy structure and 12 factors as the secondary hierarchy structure of dwelling selection criterion are deduced. The primary hierarchy are "education environment", "economic & Convenience in life", "residence safety and image", and "economic value". Second, weight value deduced from the primary hierarchy structure is showed that "economic & convenience in life(0.345)" is the highest and next is "education environment(0.262)". "Residence safety and image(0.237)", and e "economic value(0.157)" is relatively low(C.I. 0.213). Third, for the secondary hierarchy structure, the case of life convenience is showed that economic condition(0.403) is the highest, the case of educational condition is showed that education facilities(0.479), the case of residence safety and image is showed that residence area(0.490) is the highest, and the case of economic importance is showed that financial technology(0.470) is the highest.

본 연구는 미국의 직장근무자와 재택근무자의 비교를 통해, 남성과 여성의 소득차이를 살펴보고 이를 설명하는 요소들에 대해 분석하였다. 본 연구를 위해 설정된 가설은 다음과 같다.: (1) 성별은 직업과 시장노동의 장소를 선택하는데 있어서 유의한 요소이다. (2) 직업 및 시장노동의 장소가 결정된 후에도 성별은 시간당 소득에 영향을 미치는 변수이다. 연구자료로는 Census of Population and Housing, 1990 [United States]: Public Use Microdata Sample: 1/10,000 Sample이 이용되었으며, 16세 이상, 65세 이하의 응답자로 일주일에 적어도 한 시간 이상 일하는 근로자를 중심으로 하여 7,272명이 연구 대상으로 고려되었다. 직업 및 시장노동의 장소에 대한 선택에서 성별의 영향을 살펴보기 위해 판별분석이 행해졌으며, 분석 결과 교육수준, 연령, 인종, 남녀의 수, 주택구조와 함께 성별이 유의한 요소임이 밝혀졌다. 직업과 시장노동의 장소가 결정된 후 성별이 시간당 소득에 미치는 영향을 알아보기 위해 전체표본과 6개의 직업범주에 따라 회귀분석이 실시되었다. 전체표본을 대상으로 한 회귀분석의 결과, 시간당 소득을 예측하는데 있어서 성별은 유의하지 않은 것으로 나타났으나, 6개의 직업범주에 따라 시간당 소득을 추정한 결과, 성별은 모든 직업범주에서 유의한 것으로 나타났다. 그러나 재택근무자가 되는 것은 시간당 소득을 규정하는데 있어서 유의한 변수가 아닌 것으로 나타났다. 이것은 특정 직업 내에서 시장노동의 장소보다는 성별이 재택근무자에 있어서 소득의 차이를 설명하는데 중요한 요소임을 암시하고 있다. 본 연구에서 사용된 자료는 직업 및 시장노동의 장소에 대한 결정이나 소득에 영향을 미칠 수 있는 변수들에 대한 충분한 정보를 갖고 있지 않고, 또한 재택근무자의 표본수가 너무 적었기 때문에 일부 변수들은 직업의 선택이나 소득을 예측하기 위한 요소들로 포함될 수 없었다. 따라서 후속연구에서는 이를 보완해야 할 것이며, 최근 들어 우리 나라에서도 재택근무에 대한 관심이 대두되고 있으나 아직 개념정의나 그 중요성과 가치, 그리고 실태 파악과 같은 연구가 활발히 이루어지지 못하고 있으므로 이에 대한 심층적인 연구가 행해져야 할 것이다.

This study examined the degree of socioeconomic deprivation in the areas of material hardship, health, housing, employment, and social network among people using debt relief programs. The sample, 209 individuals, was recruited from major agencies offering debt relief programs, including Seoul Bankruptcy Court, Credit Counseling and Recovery Service, and Seoul Welfare Foundation. Data were collected through in-person interviews in 2016. The sample was compared in terms of the level of deprivation with the general population and the low-income group, extracted from the Korea Welfare Panel Study. The debtors group demonstrated a substantially higher level of deprivation on all the dimensions examined. For example, the proportion of people who suffered from hunger was 37.8% in the debtors group compared to 6.7% in the low-income group. The proportion of people who had suicidal ideation in the last 12 months was 57.9% compared to 19.2% in the low-income group and 2.7% in the general population. The level of deprivation was different by chapter choice of consumer bankruptcy. Policy and practice implications of the results were discussed.

The RC private constructions represent a large part of the housing stock in the north part of Algeria. For various reasons, they are mostly built without any seismic considerations and their seismic vulnerability remains unknown for different levels of seismic intensity possible in the region. To support future seismic risk mitigation efforts in northern Algeria, this document assesses the seismic vulnerability of typical private RC constructions built after the Boumerdes earthquake (May 21, 2003) without considering existing seismic regulation, through the development of analytical fragility curves. The fragility curves are developed for four representative RC frames in terms of slight, moderate, extensive, and complete damage states suggested in HAZUS-MH 2.1, using nonlinear time history analyses. The numerical simulation of the nonlinear seismic response of the structures is performed using the SeismoStruct software. An original intensity measure (IM) is proposed and used in this study. It is the zone acceleration coefficient "A", through which the seismic hazard level is represented in the Algerian Seismic Regulations. The efficiency, practicality, and proficiency of the choice of IM are demonstrated. Incremental dynamic analyses are conducted under fifteen ground motion accelerograms compatible with the elastic target spectrum of the Algerian Seismic Regulations. In order to cover all the seismic zones of northern Algeria, the accelerograms are scaled from 0.1 to 2.5 in increments of 0.1. The results mainly indicate that private constructions built after the Boumerdes earthquake in the moderate and high seismic zones with four (04) or more storeys are highly vulnerable.

We use the properties of competitive location equilibrium to study the relationship between the demand for education and the choice of primary residential location. Consumers can work and live in a comparatively high wage place where there are few education opportunities, or live in a place where education is available and commute to work. If education and employment are each location-specific, there are pooling equilibria in which consumers locate according to their preference for education. In general, the stronger the taste for education, the greater the attraction of living close to the education site and the lower the demand for other goods, including housing. Exploring the effects of the model parameters on the spatial distribution of consumers, we find that a higher frequency of trips taken to the education site, a shorter distance between the work place and the education site, or a greater out-of-pocket education cost each leads to a wider range of consumer types selecting to reside at the education location. We also find that a higher wage lowers the range of consumers who select to live near the education site.

This study aimed to introduce the main concepts of Supported Living(SL) model, very few of which have discussed in the context of S. Korea, explore the potential to employ SL model, and draw the implication for social welfare for people with developmental disabilities(DD) in S. Korea. For this purpose, this study presented the developmental background, main concepts, and principles of SL model, compared SL with supported housing and explained the features of SL model. Additionally, this study reviewed SL schemes in the UK and Australia to understand how SL schemes impact the lives of people with DD. Furthermore, this study addressed the contents of SL manuals used in the UK and Australia and identified the core aspects of SL practice. Based on the findings, this study highlighted the importance of SL as the conceptual model for independent living of people with DD and discussed the implication of SL model in S. Korea in terms of the national institution for people with DD, service agencies, and service users. This study focused on the SL model as a conceptual model for the independence of people with DD, potentials to employ SL model, and its implication for social welfare for people with disabilities in S. Korea. SL model and its application showed that SL model is effective and flexible in supporting the independent living of people with DD. Findings and implications regarding SL model could be the basis for the development of the Korean supported living system to improve the independent living of people with DD.

This study attempts to explore the relationships of Korean Immigrants with New Zealand agricultural environment, their choice of agricultural occupations and adjustments. New Zealand, based on agricultural products in its economy, was one of the richest countries during the 1950s and 1960s because of its dependency in market to United Kingdom Since 1971 when U.K joined the European Community, its economy was no more strong enough to support the living conditions in the 1950's and 1960's. Therefore, New Zealand Government initiated some programme to assist its farmers. Such supports resulted in severe financial problems of the country. Thus, reforms removing almost all support programmes has been proceeded after 1984. Though horticulture is still lower in New Zealand's exports of agricultural products, its growth has been remarkable. This was results due to the contribution of smallholdings, along with migration from city to urban fringe occurred during the 1970's and 1980's. In the 1900's it has been known that horticulture in the smallholding takes a hard works for old ages, who required further partitions their lands. Meanwhile, the rapid growth of Korean immigrants to New Zealand in the 1900's has been occurred, and this study shows one or two years periods in the search of job in case of Korean farmers. The most attractiveness in agriculture for them was that it provides simultaneously both jobs and housing. Korean farmers' land use succeeds previous owner's land use, and concentrates on green house agriculture cultivating mainly tomato and cucumber. The size of land is quite small and not comparable to New Zealand's average size, but a satisfactory levels are rather high and successful in evaluating themselves concerning current occupations, even though they have rarely experienced about agriculture before. Korean farmers attributes a high satisfaction to agricultural techniques learned from previous owners and a related support authority. The results of this study showed that Korean farmers has been absorbed into New Zealand economy rather than Korean economy. Finally, it has been pointed that the growth of Korean farmers and agriculture in New Zealand is the results of complex factors such as occupations, children's educational opportunity, and the access to the city.
