  • 통행발생은 4단계 모형의 처음 단계로 전체수요예측에 상당한 영향을 미치게 되므로 정확성이 무엇보다 필요한 단계라 할 수 있다. 현재 통행발생모형으로 도시교통 및 SOC시설 등의 계획에 널리 사용되고 있는 것은 선형회귀모형이며, 각종 사회경제지표와 통행발생량의 관계가 선형임을 전제로 한다. 하지만 급격한 도시개발이나 도시계획구조가 변경되었을 때 통행량을 추정하기 위한 사회경제지표 자료가 부족하여 추정된 통행량의 오차가 많을 수 있다. 이에 본 연구는 일반적으로 널리 사용되는 사회경제지표를 선형이란 가정을 하지 않고, 다양한 존의 특성을 반영할 수 있는 변수에 대한 시장분할을 토대로 새로운 유형별 통행발생모형을 개발하고자 한다. 본 연구에서는 교통수요예측의 처음 단계인 통행발생 모형의 예측력을 개선하기 위하여 존의 다양한 특성(토지이용, 사회경제적 등)을 고려하였다. 예측력 개선을 위한 시장분할 방법론으로는 통행 발생률을 기반으로 한 Data Mining(CART)방법과 회귀분석을 이용하였다. 연구의 결과를 살펴보면, 첫째, CART분석을 활용한 존 특성 분석결과, 유출통행은 사회경제적 요인(남녀상대비중, 연령대(22~29세))에 영향을 받고 있으며, 유입통행은 토지이용 요인(업무시설상대비중), 사회경제적 요인(3차 종사자상대비중)으로 나타났다. 둘째, 유형별 모형개발 결과 통행발생 계수 값은 유출의 경우 0.977~0.987(통행/인)이며, 유입의 경우 0.692~3.256(통행/인)로 나타나 유형구분이 필요한 것으로 나타났다. 셋째, 실측검증을 수행하였으며, 유출 및 유입의 경우 기존 모형보다 적합도가 높아진 것을 알 수 있다. 따라서 본 연구에서 개발한 유형별 통행발생모형이 기존 연구보다 우수한 것을 알 수 있었다.

  • Purpose: The purpose of this study was to analyze factors influencing the quality of life in Vietnamese married immigrant women in Korea. The factors included socio-demographic characteristics, spouse's support, and social support of Vietnamese married immigrant women. Methods: A descriptive survey was conducted to collect data from 190 subjects during the period between May and June, 2015. The randomly sampled subjects answered a self-report questionnaire translated into Vietnamese. Collected data were analyzed using SPSS/WIN 21. Results: The subjects' quality of life was found to be influenced by economic level, subjective perception of their own and spouse's health, Korean communication ability, spouse's support, and social support. The most influential factor for the quality of life was spouse's support, and next, subjective perception of their own health, Korean communication ability, and economic level in order of influence. Conclusion: The results of this study suggest that social support programs should be customized to the subjects' characteristics in order for married immigrant women to adjust themselves to new Korean environments and to lead a high-quality life through the promotion of marital relationship, Korean communication ability, health status, and economic capability.

  • This study examines the condition of transfers between mothers and adult children, analyzing the influencing factors in such transfers. Specifically the study examines the influence of financial transfers and economic resources on financial transfers and grandchild caregiving between mothers and adult children. The sample of 3719 mothers with adult children was extracted from the first wave of the Korean Longitudinal Survey of Women and Families. The major findings are as follows. Mothers's socio-demographic characteristics are important factors in explaining financial transfers between mothers and adult children. Mothers who have jobs and spouses are more likely to provide economic resource to their adult children than those who don't have. In terms of receiving economic resources from adult children, statistically meaningful factors are mothers' age, labor market participation, marital status, household income, household asset, and children's labor market participation. Especially, labor market participation of mothers and adult children is statistically powerful factor in financial transfers and caregiving.

  • Purpose: Small airports are social and economic enablers and facilitate businesses and individuals. They contribute significantly to the distribution and logistics of the local produce - be it goods or services, thereby impacting the economy but have limited access to funds and poor management restricts their development. Despite the importance, small airports in small cities struggle financially as they are unable to earn profits and have higher operating costs. In other words, this is a paradoxical situation for small airports wherein, despite losses, the regional or national public authorities still finance such airports under socio-economic obligations. Therefore, this study aims to identify the critical success factors for improving small airports' performance and propose a business model. Research design, data and methodology: Using the qualitative research, interviews with 16 stakeholders from Guwahati, Tirupati, Bhubaneswar and Dehradun airports in india were examined. Results: The analysis reveals strategic planning and low cost, non-passenger services, and development of airport economic region as the main factors contributing towards small airports' success. Additionally, providing logistics to the local businesses and creating niche markets are suggested. Conclusions: Small airports, based on their services and the means of targeting customers, could select the relevant approach to improve their overall performance and improve profitability.

  • In recent years, Vietnam's economic growth rate has been attributed to the growth of many well-managed industries within Southeast Asia. Among them is the civil construction industry. Construction projects typically take a long time to complete and require a huge budget. Many socio-economic variables and factors affect total construction project costs due to market fluctuations. In recent years, crucial socioeconomic development indicators of construction reached a fairly high growth rate. Also, most infrastructure and construction projects have a high degree of complexity and uncertainty. This makes it challenging to predict the accurate project price. These challenges raise the need to recognize significant factors that influence the construction price index of civil buildings in Vietnam, both micro and macro. Therefore, this paper presents critical factors that affect the construction price index using the fuzzy extent analysis process in an uncertain environment. This proposed quantitative model is expected to reflect the uncertainty in the process of evaluating and ranking the influencing factors of the construction price index in Vietnam. The research results would also allow project stakeholders to be more informed of the factors affecting the construction price index in the context of Vietnam's civil construction industry. They also enable construction contractors to estimate project costs and bid rates better, enhancing their project and risk management performance.

  • This study examines the factors related to university students' positive beliefs about the consequences of maternal employment. A total of 338 university students in Seoul, Gyeong-gi, and Kyungnam area provided information about their socio-economic background, parents' employment history, achievement motivation, and gender egalitarian attitude. A two-way analysis of variance showed significant interaction effects of gender and grade on positive beliefs about the consequences of maternal employment. Multiple regression analyses by gender indicated that factors related with university students' positive beliefs about the consequences of maternal employment may differ by gender. For male students, grade, and socio-cultural gender egalitarian attitude were significantly related to positive beliefs about the consequences of maternal employment. For female students, grade, family monthly income, mother's employment during elementary school, and achievement motivation were related with positive beliefs about the consequences of maternal employment.

  • The purpose of this study was to determine what factors influence various non-marriage types by considering reasons why adults are not married. The roles of individual characters and family values affecting each type of non-marriage were carefully considered. From the data of 'the Survey on the National Fertility, Family Health and Welfare in Korea in 2015', 1,053 unmarried adults who were in their late 20s to middle 40s were selected. Results show that non-marriage types among unmarried adults were diverse. Depending on sex, the distribution of non-marriage types differed. While economic reasons were predominant among men, lack of opportunities for marriage was the main reason for most women who were not married. Findings also suggest that factors such as socio-demographic characters and family values were differentially associated with each non-marriage type. These findings indicate a great deal of diversity in needs, lifestyle, and life satisfaction among unmarried young adults. This suggests that an increase in the population of unmarried adults can be related to prospectively various marriage behaviors and family patterns in our society in the future, and consequently life patterns will be different among the adult generation.

  • The changing trend of longevity from 1955 through 1985 and its interprovincal variation were studied with longevity rate as indicator. In order to detect the affecting factors of longevity rate, eleven urbanalizational, geographic-environmental, demographic and social-economic variables were employed to carry out multiple stepwise regression analysis. The data used for this study were from Population Census Reports 1955-1985 published by EPB and Year book of Public Health and Social Statistics 1986 published by Ministry of Health and Social Affairs and other reference. Subsequent to that longevity rate decreased during 1950's it has increased continuously by the yeat of 1980's. This trend was especially remarkable in the south area and the GIRI mountain area in Korea. The stepwise regression analysis shows that the longevity rates were significantly associated with the independent variables, and the dependent variables explained at the level of 93.7percent-99.9 percent. Longevity is a reflection of the demographic and socio-economic, environmental and health resourses factor etc., longevity problems cannot be dealt with in isolation. The possible research and services which could be provided by government will be discuss.

  • The purposes of this study were to identify money altitudes of college students and to examine both socio-economic characteristics and clothing purchase behaviors by different money attitudes. For this study, guestionnaires completed by 2-year and 4-year college students (n=426) were analyzed by factor analysis, cluster analysis, X²- test, and ANOVA. The results of this study were as follows: First, the money attitudes were composed of five factors and they were categorized by three clusters: cluster of considering the money as a tool for future safety, a way of approval and filling up emotions, and inclination toward stinginess and distrust. Second, the factors which were associated with money attitudes were academic level, education level of parents, household income, students' own income, and the economic level of their households. Third, in each type of attitudes, the clothing purchase behavior had four steps of decision making: problem recognition, information search, evaluation of alternatives, and the purchase. There were significant differences in the clothing purchase behavior among the money attitude styles.
