This study focused on estimating influential factors of traffic accidents and analyzing traffic accident severity of elderly and non elderly using traffic accident data. In order to reclassify elderly and non elderly traffic accident by a statistical method from entire traffic accident data, multiple discriminant analysis was applied. Also ordered logit model was applied for analyzing traffic accident severities using traffic accident severities as an independent variable and transportation facilities, road conditions and human characteristics as dependent variables. As results of the comparison between elderly and non elderly traffic accident, the traffic accident severity was affected by the age, types of traffic accidents, human characteristics and road conditions as well. Also, transportation facilities and road conditions affected to more elderly traffic accident than non elderly. Therefore, traffic accident severity would be decreased with the improvement of transportation facilities and road conditions for the elderly.

농촌인구의 급격한 감소와 고령화 속에서 농촌의 지속가능성을 위한 방안으로 귀농·귀촌의 확대가 부각되고 있다. 본 연구는 귀농·귀촌인의 생활만족도 결정요인을 분석함으로써 도시민의 농촌 이주와 성공적인 정착을 촉진하기 위한 정책적 시사점을 제공하고자 한다. 본 연구는 특히 귀농·귀촌의 주요 동기가 소득이나 농촌의 자연환경이라는 점에서, 생활만족도를 자연환경만족도와 소득만족도로 구분하여 비교 분석하는 데 목적이 있다. 분석에는 순서형 로짓모형과 일반화 로짓모형을 사용하였고, 분석자료는 2016년 「귀농귀촌실태조사」 원자료이다. 분석결과, 귀농·귀촌인의 자연환경만족도는 상당히 높으나 소득만족도는 보통 수준에 미치지 못하였다. 귀농·귀촌의 이유가 자연환경이거나, 귀농·귀촌 시 가족의 지지가 있었거나, 귀농·귀촌 이후 주변 이웃들과 좋은 관계를 유지하거나, 지자체로부터 귀농·귀촌 지원을 받은 경우, 귀농·귀촌인의 소득만족도와 자연환경만족도가 모두 높았다. 이러한 공통적인 요인 이외에 귀농·귀촌인의 소득만족도와 자연환경만족도에 영향을 미치는 요인은 뚜렷한 차이를 보였다. 소득만족도는 현재 가구소득이나 귀농·귀촌 전·후 소득 변화와 같은 경제적 요인에 의해 영향을 받으나, 자연환경만족도는 귀농·귀촌 시 배우자의 동행 여부나 지역사회 참여와 같은 사회적 요인에 의해 주로 영향을 받는 것으로 나타났다.

The prolongation of life expectancy has expanded the duration of marriage in old age. In the meanwhile, the change of life style emphasizing privacy and sociodemographic environment favoring independent living has increased the number and proportion of the elderly living with spouse only. This study, focusing on those aged 60 and over who live with spouse only the elderly, explores their marital relationship. The study pays a special attention to compare whether and how the satisfaction on the relationship with spouse would differ between husband and wife. The ordered logit model analysis is conducted based on the nationwide survey '2008 Korean National Survey of Welfare Need in the Elderly'. The results show that the marital relationship satisfaction of husbands is influenced by their own characteristics but hardly affected by his wife's. In contrast, the satisfaction of wife is influenced by husband's characteristics as well as hers. These finding reflect that women are more strongly family-centered and dependent on their husband.

This research is to analyze reasons for violation of the Self Carfree day policy. It also analyzes satisfaction of the policy participation incentives. The results are that the violation rate is increasing if the drivers live in a zone which is highly energy consuming, which has low potential demand per bus stop and low trip generation per number of houses, which therefore requires more bus routes and bus services, and in which the drivers pay more car operating fees and show less tendancy towards participation even with the 5-10% oil price increase. The results are significant at the 0.05 level.

To investigate farmers' satisfaction level and factors influencing on various agricultural and rural policies, an interview survey has been carried out in Jeonnam and Jeonbuk agricultural area, and collected 750 survey questionnaires from farmers. Satisfaction level was low in average ranging from 2.71 to 3.09 in five point Likert-scale on 22 agricultural-rural related policies. Ordered logit model results showed that satisfaction level decreased when farmers are older, had higher income, and had higher number of attendance in agricultural education programme. In addition, satisfaction level decreased when farms had main source of income from rice farming, dry-field farming, livestock farming, or facility horticulture. Lower satisfaction level was also related to location of farm. On the contrary, satisfaction level increased when the farmer had greater owned land. Among 22 agricultural and rural policies, practices that farmers prefer include Direct Payment for Rice Farming Income Compensation, Environment-Friendly Farming Service, Farmland Banking Services in order. Since direct payment policies that farmers prefer may not contribute in development of agriculture, policies can induce both farm income and agricultural development may increase farmer satisfaction level and finally resolve the income gap between the urban workers and farmers.

In recent days, school violence has been rising as a significant social problem. The occurrence of school violence can be fueled by a wide range of social and environmental contexts, thus it is very difficult to come up with the ultimate solution. Community CPTED program is one of the more comprehensive set of efforts that has been developed to prevent crime in general, and the primary focus of the study is to investigate suitable components of CPTED to prevent school violence based on the physical conditions of communities as well as the perception of residents outside of school grounds, in the vicinity of schools. Three sets of analyses in series were employed in the research. First, Ward's minimum-variance cluster analysis was used to classify the places where school violence can occur outside of school grounds based on the physical conditions recognized by local residents. Next, Importance-Performance Analysis was performed to analyze the perception of local residents about the importance and the effectiveness of CPTED components in preventing school violence. Subsequently, Ordered Logit Model was used to analyze the local residents' awareness on safety regarding school violence in their community space. Combining the results of the analyses, the priority of the community CPTED applications to prevent school violence outside of school was derived. Reflecting the local residents' perception on safety of students in their community, the sense of security in communities against school violence can be reinforced by the communities' sensible efforts in creating safer environment for their students.
