  • 본 연구의 목적은 투자자의 은퇴 시점뿐만 아니라 시장의 예측 변동성을 동시에 고려하여 Target Date Fund의 위험자산 편입 비율을 동적으로 조정하는 새로운 Glide Path를 제안하고, 은퇴 시점만 고려하여 위험자산 편입 비율이 정해지는 전통적 Glide Path와 투자 성과를 비교 분석하는 것이다. 시장 변동성의 예측치로는 역사적 변동성, 시계열모형인 GARCH 변동성, 그리고 변동성지수인 VKOSPI를 활용하였으며, 2003년부터 2020년까지의 분석 기간에서 변동성을 고려하는 새로운 동적 Glide Path의 투자 성과가 우수함을 보여주었다. 3가지 변동성 예측모형 모두에서 은퇴 시점만을 고려하는 Glide Path보다 수익률은 더 높고 위험은 더 낮아지면서 투자 성과 지표인 Sharpe Ratio가 개선되었다. 실증 분석 결과는 은퇴예정자뿐만 아니라 Target Date Fund 운용업계에 새로운 Glide Path의 활용 가능성을 제시하고 있다.

  • The purpose of this research is to determine elements affecting the out-of-pocket cost of woman. The sample consisted of 1907 women living Iksan city. The survey was conducted by means of questionnaires. The model used in the analysis of out-of-pocket cost was the Andersen-Newman model, while the analysis techniques used were stepwise multiple regression and path analysis. The number of independent variables used in the analysis was 28 in total, ie 19 predisposing components, 6 enabling components, and 3 need components. In this study, the amount of variance by the model was 17 percent. Number of restricted activity days caused by oral disease, perceived susceptibility of dental disease, having a regular dental care, dental treatment costs, education level and income were found to have significant major effects on out-of-pocket cost. Number of restricted activity days caused by oral disease was the most important variable affecting out-of-pocket cost of woman. Also out-of-pocket cost shows larger effect due to enabling components than frequency of dental utilization.

  • The purposes of this study were to identify the dimensions of advertising evaluation and to examine the influence of advertising evaluation on advertising attitude and buying intension. Also this study categorized the advertising responses. Through the pretest, 15 casual wear brand's advertisements were selected and presented as stimuli. The data was collected from 377 female university students using questionnaire and analyzed by descriptive statistics, factor analysis and multiple regression fer path analysis. The results of This study were as follows. First, 5 factors were identified for the dimensions of advertising evaluation: model/message/product/brand/tone & manner. Second, through the path analysis, advertising evaluation had direct and indirect influences on buying intension. The influences of dimensions of advertising evaluation on buying intension were also examined: model, message and product had indirect influence on buying intension mediated by advertising attitude, whereas product and brand had direct influence on buying intension. Especially, product affected considerably on buying intension. Third, advertising responses were categorized into five dimensions: tone & manner/model/message/product/brand.

  • 본 연구는 대학생의 건강지각, 건강신념, 건강증진행위의 관계를 살펴보고자 경기도 소재 대학의 대학생 309명을 대상으로 실시하였다. 조사된 설문은 문항분석과 요인분석 및 신뢰도분석을 실시하였으며, 변인 간 관계 파악을 위해 상관 분석과 경로분석을 실시하였다. 이를 통해 다음과 같은 결론을 얻을 수 있었다. 대학생의 건강지각, 건강신념, 건강증진행위간의 인과효과를 위한 경로분석은 다양한 적합도 지수에서 비교적 높게 나타났으며, 모형에 포함된 모든 경로계수는 통계적으로 유의미하게 나타났다. 구체적으로 모든 경로계수에서 유의미한 정적 관계를 나타냈으나, 건강지각과 지각된 장애, 지각된 장애와 건강증진행위에서는 부적 관계를 나타냈다. 본 연구의 결과를 바탕으로 향후 연구에서는 본 연구에서 제외된 변인에 대한 분석을 통해 건강증진행위와 관련한 외현적 타당성을 높일 필요가 있다.

  • Software piracy is widespread throughout the world. It has negative effects on the software industry and the intellectual property market. Despite various deterrent policies, the phenomenon has been getting severe. The current study investigated the antecedents of software piracy attitudes and intention. In order to identify factors and their relationship, a research model for illegal piracy behavior was developed and empirically examined through a path analysis using structural equation model. Also, this study employed a multiple group structural equation model to investigate differences in structural weights across PC software user group and smartphone application user group. It was revealed that perceived benefit, habit, social factor, self-efficacy had positive effect on attitude toward software piracy, whereas perceived risk had a decreasing influence on attitude. Relationships between piracy attitudes and intentions were significant as well. Furthermore, the cross validation between two groups showed the path coefficients of habit to attitude and attitude to intention were significantly different. Implications for research and practice are discussed.

  • The purpose of this study was to analyze a path model that investigated the relations among leisure expenditure leisure satisfaction and life satisfaction. For this purpose conceptual framework based on previous studies was suggested. The sample in this study consisted of 3,519 urban married couple living in Korea. Statistics employed for the analysis were frequencies means multiple regression and path annalysis. Empirical tests' results showed some evidence has been provided that supported the conceptual framework. In husband's model the household's leisure expenditure had vital direct effect on the husband's leisure satisfaction while it had not any effect on the husband's life satisfaction. Also in wife's model the household leisure expenditure had statistically significant direct effect on wife's life satisfaction however there was not any effect that mediated through wife's leisure satisfaction.

  • This research tested the path model which examined the direct and indirect effects of family violence experience on perpetration of dating violence among college students. Two family violence variables such as witnessing parents' marital violence and being abused by parent were the exogeneous variables in the path model, while the mediated variables were consisted of (1) the social-learning-theory-derived variables such as acceptance of violence, positive outcome expectations of using violence, and aggressive conflict-coping behavior, and (2) control-theory-derived variables such as attachment, belief, and commitment. Data were from self-administered questionnaires completed by 332 male and 469 female students selected by stratified quota sampling method. The path analysis was done for males and females separately, since females reported significantly higher degree of dating violence than males. Results of the path analysis showed that first, for both males and females, being abused by parents directly and indirectly influenced dating violence, while witnessing parents' marital violence did not have effect on dating violence either directly or indirectly. Second, for male students, acceptance of violence and conflict coping behavior found to be the mediated variables in the effect of being abused by parents on dating violence. Third, for females, a control-theory-derived variable of belief as well as all three social learning theory-derived variables mediated the influence of being abused by parents on dating violence.

  • There have been traditional approaches to model radio propagation path loss mechanism both theoretically ad empirically. Theoretical approach is simple to explain and effective in certain cases. Empirical approach accommodates the terrain configuration and distance between base station and mobile unit along the propagation path only. In other words, it does not accommodate natural terrain configuration over a specific area. In this paper, we propose a spatial prediction technique for the mobile radio propagation path loss accommodating complete natural terrain configuration over a specific area. Statistical uncertainty analysis is also considered.

  • 본 연구는 최근 SNS의 폭발적인 성장에도 불구하고 공개형 SNS에 비해 폐쇄형 SNS가 활성화되고 있는 것이 장기적으로는 SNS 콘텐츠를 제공하는 기업이나 SNS를 이용해 마케팅전략을 구사하는 기업들에 모두 부정적인 영향을 미칠 것이라는 점에 주목하고 SNS 이용저하의 원인을 찾고자 하였다. 연구수행을 위해 대학생 이상의 남녀 성인 총 205명을 대상으로 설문을 실시하고 이중 불성실한 응답을 한 8명을 제외한 197명의 유효설문지를 분석에 활용하였다. 수정된 원형/행동경향 모형에서 제안한 두 가지의 경로인 즉흥적이거나 상황에 반응하여 행동하는 행동경향의 경로와 합리적으로 생각하여 행동하는 경로가 각각 존재한다는 것을 확인하였다. 이론적 근거와 수정지수를 사용한 수정모형 분석결과 상호작용성은 즉흥적이거나 상황에 반응하여 행동하는 행동경향 경로 뿐 아니라, 합리적으로 생각하여 행동하는 행위의도 경로에 영향을 미치는 양면성을 지니고 있다는 것을 확인할 수 있었다.
