  • Purpose - A traditional retail market is a place that offers economic opportunity to employees and employers alike it also is a place where the community can meet. The Korean government has invested three trillion won to improve physical and non-physical aspects in traditional retail markets since 2004. However, little research on this has been conducted. We explore this research gap that could lead to theory extension. We analyze consumption behavior with respect to traditional retail markets through an empirical analysis, thus overcoming limits in previous research. We empirically analyze policy effects of traditional retail market projects supported by the Korean government. Research design, data, and methodology - We propose a traditional retail market improvement plan via the relation between cause and effect resulting from the analysis. More specifically, logit analysis was carried out with 1,754 consumers in 16 cities nationwide. In order to analyze consumer consumption behaviors nationwide, the probability was analyzed using a logit model. This research analyzes the link between support and non-support by the Korean government using binary values. The dependent variable is whether Korean government support is implemented; the binomial logistic regression is used as the statistical estimation technique. The object variables are:1 (support) or 0 (nonsupport), and the prediction value is between 1 and 0. As a result of the factor analysis of questions related to attributes of service quality, four factors were extracted: convenience, product, facilities, and service. Results - The results indicate that convenience, product, and facilities have a significant influence on consumer satisfaction in accordance with the government's traditional retail market support. Additionally, the results reveal that convenience, product, facilities, and service all have a significant influence on consumer satisfaction in a traditional retail market's service quality and consumer satisfaction. Finally, the analysis indicates that the highly satisfied traditional retail market customer has a significant influence on revisit intention. Moreover, the results reveal that the highly satisfied traditional retail market customer has a significant influence on recommendation intention. Conclusions - This research focused on consumers nationwide to measure policy effects of traditional retail markets compared to previous research that focused on one traditional retail market or a specific area. We verified the relationship of service quality and customer satisfaction and consumer behavior based on service quality theory. The results indicate that consumer satisfaction of traditional retail markets supported by service quality factors has a significant impact. In a concrete form, the results indicate that these effects are from facility modernization projects and marketing support projects of the Korean government. The results also imply that these facility and management support effects from the Korean government have been consistent. We realize that the Korean government has to selectively support traditional retail markets in major cities and small and medium-sized cities. To that end, the Korean government needs to select a concentration strategy for the revitalization of traditional retail markets.

  • 고속도로 교통사고는 타 도로에 비해 고속주행으로 인한 사고피해가 클 수 밖에 없으며, 특히 인적피해는 사회적인 큰 문제가 되고 있다. 본 논문에서는 고속도로 사고 중, 인적피해가 발생한 사고와 그렇지 않은 사고에 대한 사고 특성의 차이점을 규명하고자 하였다. 이를 위해 로지스틱 회귀모형을 활용하여, 두 사고 유형에 영향을 주는 사고 요인들을 찾아내었다. 분석 결과, 도로선형이 직선이고 방호울타리가 존재하며, 남성, 비고령자일 경우 운전자 과실 및 과속으로 인해 인적 사고로 이어질 가능성이 높았으며, 이에 대한 대비가 필요할 것으로 판단된다. 본 연구결과를 토대로, 인적피해가 발생한 사고와 이와 연관된 주요 설명 인자들을 찾아냄으로써 고속도로 안전정책 수립에 중요한 시사점을 찾아낼 수 있을 것이다.

  • 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.

  • Using the first wave of KLoSA(Korean Longitudinal Study of Ageing) beta version, this study analyzed factors affecting early retired men's subjective life satisfaction through Binary Logit and Multiple Regression. Total 552 men were selected as a sample. The main results of empirical analysis in this study were as follows: The retirement reason(health-) and monthly household income(+) affected whether they were satisfied with the retirement life or not and subjective life satisfaction over all. Especially, the retirement reason(health-) had a stronger effect on whether early retired min were satisfied with the retirement life or not and their subjective life satisfaction than monthly household income revealed significant variable in previous studies. This result represents that the retiree's life satisfaction analysis model must include retiree's characteristics at the time of retirement as well as retiree's current status characteristics or socio-economic characteristics.

  • Bankruptcy prediction has drawn a lot of research interests in previous literature, and recent studies have shown that machine learning techniques achieved better performance than traditional statistical ones. This paper employs a relatively new machine learning technique, support vector machines (SVMs). to bankruptcy prediction problem in an attempt to suggest a new model with better explanatory power and stability. To serve this purpose, we use grid search technique using 5-fold cross-validation to find out the optimal values of the parameters of kernel function of SVM. In addition, to evaluate the prediction accuracy of SVM. we compare its performance with multiple discriminant analysis (MDA), logistic regression analysis (Logit), and three-layer fully connected back-propagation neural networks (BPNs). The experiment results show that SVM outperforms the other methods.

  • 본 연구는 Oxford Economics에서 제공하는 Global Cities Forecast 자료(2013)를 이용하여 한국의 7대 광역시를 포함한 전 세계 주요도시의 경쟁력지수 및 분배지수를 산출하고 그 종합순위를 정리하였다. 도시경쟁력지수는 규모지표, 비율지표, 성장률지표 등 총 18개 경제관련 지표를 선택하였고, 분배지수로서 지니계수를 이용하였다. 경쟁력지수와 지니계수 간의 관계를 분석하기 위하여 LOGIT 회귀모형을 이용하여 분석하였으며 추정결과 소득불평등(지니계수) 증가는 5년 시차로 볼 때 도시경쟁력지수 또한 경제성장률 변화에 음(-)의 영향을 미치고 있으며 통계적으로 유의하였다. 지니계수가 높을수록 도시경쟁력에 부정적으로 영향을 미친다는 추정결과에 따라 도시경쟁력지수에 분배지수를 포함시켜 총 19개 지표로 세계주요 도시 및 국내 7대 광역시의 글로벌 도시경쟁력 위상을 정리하였다. 2012년 실질가치 기준으로 계산된 서울의 도시 종합경쟁력 순위는 2010년 세계 59위, 2015년 세계 74위, 2030년에는 세계 185위로 급격히 하락하는 것으로 나타나고 있으며 나머지 6대 광역시의 종합경쟁력지수도 모두 하락하는 것으로 나타났다. 도시경쟁력 하락은 장기적으로 국가경쟁력 하락을 의미하므로 도시경쟁력 확보를 위한 문제점 진단과 전략적 방안의 강구가 절실히 요구된다.
