The purpose of this study is to segment and examine urban farmers behavior by applying a two-step cluster analysis and multi-nominal logit model. The data were collected by a telephone survey with two-staged stratified random sampling in the cities around the country for the purpose of acquiring representative data. Respondents were asked to describe their awareness of urban agriculture, their agricultural activity, and sociodemographic characteristics. Among 2,000 cases, 381 cases(19.1%) which were of participants in urban agriculture were analysed in SPSS. From the findings, 27.3% of respondents had heard the word 'urban agriculture', and 25.5% of them regarded themselves as urban farmers. Four different clusters were derived from two-step clusters based on motive, place, companion, area and hours. They were 'Large scale hobby farming(cluster 1)', ‘Weekend farm/ hobby farming(cluster 2)', 'Land/ Self-supporting farming(cluster 3)', and 'Small scale hobby farming(cluster 4)'. The result of multinomial logistic regression showed that there were significant differences among these four segmented groups in terms of age, city size and housing type. In other words, there is quite a possibility that urbanites select different urban farming types according to their socio-demographic profiles. Therefore, the urbanite profiles can be used as the basis for promoting policy of several urban agriculture types. According to the result, policy directions for facilitating urban agriculture were presented.

The rapid rural urban migration and aging has generated an over-depopulation problems in rural areas since the 1980s. The purpose of this study constructs the marginal size of rural over-depopulated village through the analysis of the residential disparities such as farmer's ratio, basic life service accessibility, and levels of social and economic factors for each village community. This marginal scale could support evaluating diverse rural policies, which have been planned to apply to the rural development programs at the village level. The major challenges for over-depopulated villages are the lack of basic facilities, production infrastructures and inactive communities in the village. Therefore, the quantitative analysis of rural residential disparities according to rural village scale can provide the criteria for rural over-depopulated villages. We utilized Korea Agricultural Survey Data(2010) including specific residential condition of village level. The present study adopt multinomial-logit model for quantitative analysis of different village scales and decomposition techniques to separate the direct effect by the village scale factor from the endowment effects by regional or area characteristics, and residual effect by unknown factors. The present study found that the minimum scale of a rural over-depopulated village was 40 and 60 houses for the respective conditions of farmer's ratios less than 50% and greater than 75%. It was concluded based on the study findings that threshold scale could support evaluating the diverse rural policies, which have been planned to apply to the rural development programs at the village level.

본 연구는 개인이 행복한 삶을 영위하는데 있어 규칙적인 체육활동 참여가 미치는 영향력과 체육활동 참여 결정요인을 파악하는데 목적이 있다. 연구 목적 달성을 위해 '2014년 국민생활체육참여실태조사' 자료를 이용하여 규칙적 체육활동 참여 집단과 그렇지 않은 집단 간 행복감 차이 교차분석, 다중회귀모형을 통한 규칙적 체육활동이 행복감에 미치는 영향력과 영향요인을 분석하였다. 교차분석과 이항로짓 분석을 통해 집주변 체육시설 인지 여부에 따른 체육활동의 참여 차이와 영향요인도 분석하였다. 분석결과 규칙적 체육활동에 참여하는 집단이 그렇지 않은 경우에 비해 행복감이 높은 것으로 나타났고, 연령, 교육수준, 직업유무, 소득, 결혼여부, 건강수준이 행복지수에 정(+)의 영향력을 미치는 것으로 나타났다. 집주변 체육시설 인지 여부와 규칙적 체육활동 참여와의 관계 분석 결과는 두 변수 간에 정(+)의 관계가 있는 것으로 나타나 집주변 체육시설 인지 여부가 참여 동기로 작용하는 것으로 분석되었다.

본 연구는 교통사고자료를 이용하여 고령자 집단과 비고령자 집단 간의 교통사고요인을 파악하여 각 요인들이 교통사고 심각도에 미치는 영향의 크기를 분석하였다. 나이에 의해 구분된 고령자와 비고령자 집단을 교통사고자료를 이용한 통계학적 방법에 의해 재분류하였으며, 교통사고 심각도에 미치는 영향요인을 분석하기 위해 심각도를 종속변수로 두고, 교통시설, 도로환경, 개인별특성에서 17개 독립변수로 정하여 순서형 로짓모형으로 분석하였다. 고령자 집단과 비고령자 집단의 교통사고 영향요인을 분석하여 비교한 결과, 사고 당사자의 연령뿐만 아니라, 사고유형이나 운전자 개인의 특성, 도로환경도 교통사고에 영향을 미치고 있음이 나타났다. 또한 고령자 집단과 비고령자 집단은 교통사고 심각도에 미치는 영향변수의 종류와 크기가 각각 다른 것으로 나타났다. 이는 각 집단의 개인적 특성에 적합한 교통시설이 개선된다면 교통사고의 심각도를 줄일 수 있음을 의미하는 것이라 할 수 있다.

The purpose of this study is to observe whether intergenerational differences exist in support among major Korean political parties and, if so, how they exist, based on the results of the survey conducted nationwide. To achieve the purpose of the study, a questionnaire was prepared based on conjoint analysis, and the collected data was analyzed by applying a random parameter logit model. The main results of model analysis are summarized as follows. First, among the policy variables, statistically significant results were observed in the generation of 20s and 30s for the education variable. It was found that both 20s and 30s aimed for equal education at a higher level than other generations. Especially, the highest intensity aim for equal education culture was observed in the 20s. Second, the coefficients of major political parties were observed with a high level of statistical significance. This appears to be a result suggesting that voters decide on their voting behavior through thorough policy comparisons in addition to comprehensive consideration on various current issues. Third, a clear support for conservative parties was observed in the generation of 20s. A clear and intense distribution of preference for political parties classified as conservatives was observed in the 20s generation, which can be said to be mainly college students. This seems to be a profound founding related to the issue of "conservatization of the 20s," which has recently become a hot topic in Korean society. Fourth, a high level of support for progressive parties was observed in the 30s and 40s. The Justice Party can be classified as a minority party in the National Assembly House as of January 2019. Nevertheless, it was maintained at a relatively high level in national recognition, and it is presumed that the background was high level of support from the 30s and 40s. Fifth, a large level of standard deviation was observed in the preference for conservative parties in the 50s. This means that some respondents who are in their 50s or older strongly support the Liberty Korea Party, and some respondents in the same generation strongly disapprove it. Due to this countervailing power, it seems that the average support level for the Liberal Korean Party is low in the generations of 50s and older.?

본 연구는 노후소득보장제도의 노인 빈곤 영향요인에 관해 근로를 중심으로 살펴보았다. 이를 위해 한국복지패널 7차~16차 자료를 바탕으로 패널로짓분석을 실시하였다. 분석결과는 다음과 같다. 노인 빈곤에 영향을 미치는 인구사회학적, 경제, 건강변수를 통제하더라도, 노후소득보장제도 중 국민연금 수급액과 특수직역 연금 수급액은 노인 빈곤과 부정적으로 연관되어 있다. 반면에 기초연금 수급액과 국민기초생활보장 수급액은 노인 빈곤과 긍정적으로 연관된 것으로 나타났다. 둘째, 국민기초생활보장 수급 노인이 근로를 하는 경우 탈빈곤 가능성이 높은 것으로 밝혀졌다. 이는 빈곤완화효과를 높이기 위해서는 기초연금제도의 재구축이 필요하고, 국민기초생활보장제도와 노인일자리 정책과의 결합이 필요함을 시사한다. 끝으로, 전반적인 노인빈곤을 완화하기 위해 기초연금, 퇴직연금을 포함한 다층노후소득보장체제의 재구축을 제언하였다.

본 논문은 서베이 데이터를 이용하여 한국의 연료유형에 따른 자동차의 잠재적 수요를 분석한다. 종속변수는 휘발유, 경유, 하이브리드, 전기, 수소를 포함한 향후 희망 자동차 연료유형이며, 주요 설명변수는 응답자의 인구학적 특성과 희망 자동차 연료 유형 선택 시 고려사항, 주성분분석으로 추출한 환경에 대한 인식이다. 다항로지스틱모델을 이용한 분석결과는 다음과 같다. 연비와 운행편의를 고려하는 응답자들의 하이브리드차에 대한 수요는 높아지는 반면에 전기차와 수소차에 대한 수요는 낮아진다. 환경에 대한 부정적인 인식이 있는 응답자들의 휘발유차와 경유차에 대한 수요는 높아지는 반면 전기차에 대한 수요가 낮아진다. 환경에 대한 우려를 표하는 응답자들의 하이브리드차에 대한 수요는 증가하는 반면에 전기차에 대한 수요는 감소한다. 이와 대조적으로, 환경 친화적인 응답자들의 경유차에 대한 수요는 감소한다.

This study analyzed household expenditure patterns using the 1990 Korean Consumer Expenditure Survey and identified the factors determining a household's probability to be in an expenditure pattern. The results of cluster analysis revealed five expenditure patterns: Education and Recreation-dominated; Necessities-dominated; Miscellaneous expenditure-dominated Housing dominated; and Transportation and Communication-dominated patterns. Based on the results of descriptive and Logit analyses household income household size age of household head and housing status were major factors to determine the type of househld expenditure pattern.

This paper proposes a method in one-way layouts for longitudinal data with informative drop-out. When dropouts are informative, that is, correlated with unobserved data and/or the previous observed data, the simple imputation methods such as 'last observation carried forward' (LOCF) methods would arise the bias of the testing models. The maximum likelihood procedure combined with a logit model for the drop-out process is proposed to test treatment effects for one factorial designs and compared with LOCF method in two examples.
