This study aimed to analyze characteristics and factors affecting of depression by households type of elderly with disabilities. Data were analyzed using chi-square test, logistic regression analyses according to the PSED. Data were 608 individuals. First, The one-person households group showed significantly female, non-capital, severe disorder, lower health status, lower economic level, higher help for daily life, higher experience of discrimination, lower satisfaction with relationship, lower participation in social activities. Second, Factors affecting depression included experience of discrimination, participation in social activities. Multi-person group included gender, occupied area, health status, economic level and one-person group were help for daily life. In order to reduce depression, it is necessary to reduce experience of discrimination, improve awareness of disability, health care, economic supports and so on. This study is meaningful in that it classifies households types. In the future, there is a need to longitudinal studies.

This study directly analyzes the wage distributions rather than indirectly looking at a few of their moments. It also investigates wage distributions using various descriptive and semi-parametric methods. The wage distributions of Korean manufacturing industries can in general be represented by three distinct forms, underdeveloped, advanced and the medium of the two. The discrepancies in these distribution forms are explained by differences in the labor-type distributions and their weights in the composition of wage distribution forms, and further clarified through various descriptive statistics based on them. However, the descriptive statistical analysis has a limit in that it shows mixed outcomes of different categoric variables. Then, this problem is resolved by applying a semi-parametric estimation of hazard function and the marginal effect evaluations of variable changes on estimated distributions not on the function. As a result of this marginal analysis, the common features and differences of categoric variables and their intensities of effects on distributions are revealed.

As the transition to the knowledge-based economy has been accelerated in the 21st century, the importance of the service industry has been highlighted. As the proportion of knowledge service industry in the economy and the related employment rate are continuously growing, it is necessary to bring innovation to the industry in order to increase competitiveness. In this study, the innovation types are diversified into product, process, organization, and marketing and the influencing factors have been analyzed with knowledge service firms. The complex causal relationship that is linked to the innovation performance has been analyzed by the structural equation with each innovation types as the intervening variables. The results of this study can be summarized as follows. The innovation capacity of firms in knowledge service industry has very strong positive effects either directly or indirectly on product innovation, process innovation, organizational innovation, marketing innovation, and the revenue and employment of the firm. On the other hand, innovation support policy through government intervention produce negative impact on product innovation and they do not create meaningful impact on the total effect on the revenue nor the employment growth. The innovation should ultimately create effects on the revenue and the employment of the firm. And the government support policies should be carefully designed in consideration of the final destination point of this complex causal structure.

Area type is often used in freight demand analysis and logistics planning models. For example, in freight transportation planning. area type variable is most often commonly used in freight generation (attraction) model. Yet a reliable, forecastable and measurable definition or area type is generally not documented. In fact, there is little literature on the subject of predicting area type in the context of freight planning models. This can be troublesome when applying models to long-range logistics planning where significant changes in population and employment result in changes in the general character of an area. Through the use of Discriminant Model, GIS (Geographic Information System) analysis and Delphi methods, this paper presents the successful exploration for a quantifiable means of determining area type.

탄산수내 REEs의 함량과 거동특성을 알아보기 위해 암석시료, 탄산수 및 침전물에 대한 REEs 분석을 실시하였다. 탄산수가 산출되는 인접지에서 채취한 암석시료들은 물의 유형에 따라 큰 농도변화를 보여주지 않으며, 대체적으로 LREEs가 부화된 특성을 보여주고 있다. 유형에 따른 탄산수의 REEs 농도변화는 서로 상이한데, Na-HCO$_3$ 유형은 강한 HREE의 부화를 보여주지만, Ca-HCO$_3$ 유형은 HREE의 부화를 보여주지 않고 감소하는 경향을 보이며, 화학적으로 중간 유형에 속하는 Ca-Na-HCO$_3$ 유형 탄산수는 Eu을 제외하고는 전체적으로 flat한 분포를 보여준다. 탄산수에서 침전된 침전물과 침전물을 제거한 물의 REE의 유형은 침전물이 발생되기 전의 탄산수와 유사한 경향을 보이지만, 침전물의 발생으로 인한 특징적이고 강한 anomalies를 보여준다. 침전된 침전물의 REEs 특성은 침전물이 발생되기 전의 원 탄산수와 거의 유사한 분포특성을 보여준다. 반면에 침전물을 제거한 탄산수에서는 탄산염침전물의 침전과 연관되어 매우 강한 Eu anomalies를 보여주며, 대체적으로 HREE가 부화된 특성을 보여주었다. 탄산수내 가장 우세한 REE 종은 CO$_3$$^{2-}$ 종이며, CO$_3$$^{2-}$ 복합체 때문에 REEs의 분별작용 (HREE의 부화)이 일어나는 것으로 판단되 었다.

최근 정보기술의 발달과 COVID-19으로 인해, 많은 유통의 판도가 바뀌었다. 비대면의 급증으로 배달문화와 온라인 쇼핑과 온라인 회의 등이 성행하며 익숙해지고 이로 인해 디지털 전환이 더욱 빠르게 가속화 되었다. 중국에서 시작되었던 라이브 커머스도 이 시기를 틈타 한국으로 들어왔고 라이브 커머스의 발전이 시작되었다. 이에 따라 라이브 커머스에 관한 연구도 많이 나오고 있는데 연구들이 라이브커머스의 특성만을 다루는 것에 한계점을 느꼈다. 이에 본 연구는 라이브 커머스의 특성에서 나아가 이 특성으로 인하여 진정으로 혜택을 볼 수 있는 소상공인들에 초점을 맞추기로 하였다. 소상공인들이야말로 라이브커머스를 이용하는 80%를 넘는 비중을 차지하고 있는 사용자이자 판매자이다. 하지만 그럼에도 불구하고 아직까지도 많은 판매자들이 라이브커머스를 어렵게 생각하고 전문 방송인을 고용하거나 대행사를 고용하여야만 라이브커머스 방송이 가능하다고 생각하여 시작을 못하고 있다. 본 연구에서는 실험을 설계하여 판매자가 직접 라이브 커머스 방송을 진행하여도 충분히 소비자에게 긍정적인 영향을 줄 수 있고 매출액과 유입수에도 영향을 끼칠 것이란 가설을 설정하였다. 쇼호스트와 관여도라는 변수를 설정하여 2 by 2 실험을 설계하였다. 쇼호스트는 방송전문가인 일반적인 대행사를 섭외하여 방송을 능숙하게 하고 중간에 재미적인 요소를 집어 넣는 쇼호스트와 제품 전문가인 판매자를 직접 방송하게 하여 제품에 대한 전문성을 넣어 소비자의 반응을 살펴 보았다. 관여도는 고관여 제품과 저관여 제품을 식품군으로 비교하는 것으로 설계하는 것으로 연구를 진행하였다.

The purpose of this study is to establish the concept of the blind zone of social services and analyzing the conditions by children, the elderly, the disabled, and the poor. This study used the raw data of demand/supply of social service and sample size is 4,038. Results of the study were as follows. First, in terms of the coverage, the biggest blind zones of social service are the employment support and cultural service. These results were similar for all households. But, it is noteworthy that the size and proportion of blind zones of housing support services for children, counseling services for elderly are relatively big. Second, in terms of adequacy, the most serious blind zones of social service are health and the employment support service. Especially, the elderly, the disabled, and the poor are not the most adequate adult care services and children are community service. Based on such findings, this study suggests expansion of employment support services and health care, monitoring for the services analyzed to be over-supply, and intensive involvement of private sectors about the services provided by the government of a large blind zone.

The purpose of this study is to empirically analyze factors which influence social and economic performance of social enterprises, and to examine the correlation of factors affecting social and economic performance. This study was conducted following the hypothesis that the organizational characteristics(organizational type, certification type, certification year, social service supply type, and external grants) of social enterprises affect social and economic performance, and that significant correlation exists between social and economic performance. This study collected the disclosure materials of 219 social enterprises certified between 2007- 2014 from the directory of the Korean Social Enterprise Promotion Agency. The study results are as follows: First, organizational characteristics affect social performance(i.e. jobs for the vulnerable classes). In addition, certification year and external grants had a positive effect on social performance. Second, the organizational characteristics affect the economic performance(i.e. sales), and certification year and external grants had a positive effect on economic performance. However, organizational type had a negative effect on the economic performance(i.e. sales). Third, analysis found a positive correlation of factors affecting social and economic performance. This study suggests the need to diversify support policies according to the number of authentication years in order to promote self-reliance and sustainability by maximizing the social and economic performance of social enterprises.

This study analyzed the effect of career preparation behavior of female college graduates on their job satisfaction. The results of this study are as follows: First, the relationship between job satisfaction and career preparation behavior and a regression analysis of job satisfaction were all examined. This study used the original data from the Korea Employment Information Service for '2012 College Graduates' Occupation Route Survey'. The subjects of this study were 1,569 women in the science and engineering fields (649 engineering graduates, and 920 science graduates). The data was analyzed by frequency analysis, independent sample t tests, correlation analysis, and hierarchical multiple regression analysis using SPSS WIN 19.0. As a result, women with 4 years of college have higher job stability and job satisfaction than college students, but the reasons for major selection, university type, college location, and department. The results of this study are as follows. First, the effect of the variables on career satisfaction and job satisfaction was not statistically significant. This suggests that the type of college does not have a significant effect on job satisfaction if the university systematically prepares people for a career and the university suits a person's aptitude.
