이 논문은 포퍼의 후기 확률론인 성향적 확률론에 대한 것이다. 포퍼가 확률에 관한 성향이론을 제시한 가장 중요한 동기는 단일 사건에 확률값을 부여하기 위함이었다. 그의 성향이론은 전기와 후기로 나누어지는데, 전기의 이론은 성향을 반복가능한 조건들의 집합으로, 후기의 이론은 성향을 특정 시각에서의 우주의 상태로 설명한다. 이 글은 포퍼의 전기와 후기 성향이론이 성공적이지 않음을 논증한다. 전기 성향이론에 대해서는 가장 좁은 준거집합의 원리의 문제에 부딪혀서 단일 사건에 대하여 객관적인 확률값을 부여할 수 없기 때문이고, 후기 성향이론은 성향을 약한 인과라고 해석하는 문제와 함께 포퍼 자신의 의도와 달리 형이상학적인 이론이 되어버렸기 때문이다.

본 연구의 목적은 미국 여대생의 자의식, 물질주의성향, 충동구매와 과시적 소비성향간의 관계에 관하여 조사하는데 있다. 상징적 자기완성이론을 이론적 근거로 하여 가설을 설계하였으며, 설문지 조사법을 이용하여 자료를 수집하였다. 편의표본추출법을 적용하여 미국 중서부지역의 한 대학교의 여대생 315명을 연구대상으로 설문조사를 하였으며, 최종적으로 296명의 응답을 연구결과분석에 이용하였다. Stepwise 회귀분석을 통한 분석 결과 공적 자의식은 물질주의성향과 충동구매성향 및 과시소비성향에 정적 영향을 미치는 것으로 나타났으며, 사적 자의식은 과시소비성향에 부적 영향을 미치는 것으로 나타났다. 또한, 단순회귀분석을 통한 분석 결과 물질주의성향과 충동구매성향 및 과시적 소비 성향 간에 정적인 관계가 있는 것으로 나타났다. 본 연구는 자의식, 물질주의성향, 충동구매와 과시소비 성향간의 관계 메커니즘을 증명해 보임으로써, 사회 심리학적 소비자 행동연구에 이론적 틀을 제시하였다. 또한, 본 연구결과는 미국 여대생을 표적 시장으로 하는 기업이 표적소비자의 소비행동과 심리를 이해하는데 중요한 자료로 이용될 것으로 기대된다.

The propensity score method is used to minimize the bias level in social survey, which comes from nonresponse. The theoretical concept and the background of the propensity score method is discussed first. The propensity score method was first applied in the epidemiology observational study. I have summarized the process of the three propensity score methods that were used to reduce estimation bias in this study. Matching by propensity score is applied to the relatively large control group. Subclassification has the advantage of using whole control group data and regression adjustment is applied to multiple covariates as well as propensity score of each unit is computable and usable. Lastly, the application procedures of propensity score method to reduce the nonresponse bias is suggested and its applicability to real situation is reviewed with the existing data.

직설법적 조건문의 이론이 해결해야 할 문제 중 하나는 각자 옳을 것 같지만 모두 참일 수 없는 직설법적 조건문에 관한 세 원리들이 있다는 것이다. 먼저 직설법적 조건문을 진리 함수적으로 분석하는 것은 '주관적 확률'을 고려할 때 이 문제를 해결할 수 없다고 논증할 것이다. 필자는 여기서 직설법적 조건문에 관한 성향적 분석을 제시하고 이 이론이 세 원리들의 문제를 해결한다고 주장한다. 그리고 잘 알려져 있는 직설법적 조건문의 수용 조건 혹은 주장가능성 조건을 제시하는 아담스 논제는 조건부 확률이 두 절대적 확률의 비로 정의된 다면 옳지 않을 것이라고 주장한다. 조건부 확률을 성향적으로 정의할 경우에만 아담스 논제는 옳을 수 있다. 마지막으로 아담스 논제의 주장가능성 조건을 진리 조건으로 제시하는 이론도 논박될 것이다.

The contingency theory of leadership was proposed by F. Fiedler. In his theory, he divided the group into Task oriented and Relationship-oriented people based on work-style by LPC(Least Preffered Co-workers) test. This survey searches significance of interaction usage depending on which group has more aggressive interaction on the address list with mobile phones focusing on the differences between mainfunctions (name, cell phone, group name) and sub-functions (birthday, Photo, E-mail). Itis the hypothesis that the relationship-oriented group has more interaction than the task-oriented group which was identified through the analyzed usage of the address list. Results show that the contingency theory was not appropriately related with the research. Interaction usage by the following task based on Fiedler's contingency theory of leadership isn't related much. However, by discovering the interesting patterns by the test, this research is able to guide human-centered address design directions.

According to consumer behavior theory, human propensity can be divided into two regulatory focus types: promotion and prevention. These two types have much influence on the consumer's decision in many diverse areas. In this research, we apply regulatory focus theory to personalized recommendation to minimize the cold start problem and to improve the performance of recommendation algorithms. To achieve this goal, we extract the consumer behavior variables and information exploration activity index from web shopping logs. We then use them for classifying regulatory focus of the consumer. This research has the contribution to show the possibility of systematization of consumer behavior theory as an interdisciplinary research tool of social science and information technology. Based on this attempt, we will extend the research to IT services adapting theories on other areas.

This study explores how fear of isolation and willingness to speak out are affected by cultural values. The cross-cultural studies on the spiral of silent theory were conducted mostly in Eastern and Western countries and compared the results. It attributed to the results to the "individualist-collective" attitude difference. However, it did not explain the differences in the same individualism societies as well as in the collectivism societies. Thus, this study examined the impact of cultural values on the spiral of silence theory with 'individualism-collectivism' and 'uncertainty-avoidance'. To that end, the current study conducted online surveys in India, South Korea, the United States and Spain where have different levels of individualism, collectivism, and uncertainty-avoidance. As a result, individualism contributed to lower the fear of isolation, and collectivism and uncertainty avoidance have raised the fear of isolation. Besides, individualism and uncertainty avoidance also reinforce the willingness to speak out, while fear of social isolation has been shown to weaken the willingness to speak out. The study also found that fear of isolation has the mediated effect of individualism and collectivism on the willingness to speak out.

The aim of the study is to look at the relationships among emotional dimensions, commitment to environment, consumer typology, and quality of life. For this study, 303 students completed the questionnaires and SPSS and Amos 4 were employed. The findings are: First, positive emotion increases commitment to environment. Second, commitment to environment encourages green consumer behaviors and quasi-green consumer behaviors while it reduces non-green consumer behaviors. Third, green consumer behaviors increase quality of life while quasi-green consumer behaviors and non-green consumer behaviors do not have any influence on quality of life. Some practical implications are included.

This paper is concerned with identifying the determinants of committing digital piracy in university settings. Using a theoretical model based on Theory of Reasoned Action, the causal relationship among the research variables, including intention to commit digital piracy, attitude, subjective norm and fear of legal consequences, is developed. Results from 295 survey responses indicate that fear of legal consequences affect the subjective norm and the attitude, which in turn influence the intention to commit digital piracy. In addition, relativism based on EPQ(Ethics Perception Questionnaire) is introduced as a moderating variable. The relative influences of path coefficients are investigated and implications from findings are also discussed.

This study investigated the tax compliance applying framing effect, with the influence of detection rates, client advocacy, risk seeking tendency on the amount of income declared. Questionaires were filled in by CFA in Busan. Questionaires involve three cases (newly founded company, loss-expected company, gain-expected company). Respondents declared least in newly founded company, next loss-expected company, to gain-expected company. Respondents declared more as detection rates rose. As client advocacy increases, newly founded company and loss-expected company declare less, while gain-expected company declare more. As risk seeking tendency increases, newly founded company and loss-expected company declare less, but gain-expected company. Finally the interaction effect between client advocacy and risk seeking tendency is supported.
