소비자의 집단 구성원에 대한 자아지각은 소비자 의사결정에 어떠한 영향을 미칠까? 집단소비자 상호간에 영향을 미치는 의사결정 상황이나 소비자 개인적 의사결정상황 등 의사결정 상황에 따라 다르게 영향을 미칠까? 본 연구는 소비자가 집단의식을 인식할 때 개인적 차원과 집단적 차원에서 행해지는 의사결정이 어떻게 이루어지는지를 검증하고, 이때, 소비자의 위험회피성향에 따라 소비자 의사결정이 어떻게 조절되는가를 2 가지 실험을 통해 밝히고자 하였다. 미국 오레곤 주립대학교의 아시아계 학생들을 대상으로 2 가지 실험을 실시한 결과, 집단의식을 지각한 소비자는 집단관련 의사결정은 물론 개인관련 의사결정에서도 긍정적 영향을 미치는 것으로 나타났다. 그러나, 위험회피성향의 조절효과에 대한 실험결과는 집단의식을 지각한 소비자와 집단의식을 지각하지 않는 개인적 소비자 모두 처벌에 관한 상황에서 형평성 선호와 협상적 대안을 선택하는 것으로 나타나 집단의식지각의 의사결정에 대한 위험회피성향의 조절효과는 부분적으로 나타났다.

This study set out to organize and apply a group program designed to resolve the psychological career barriers of university freshmen and test its effects on their psychological career barriers, self-efficacy in career decision-making, and self-determination. For this purpose, the investigator divided the subjects into a treatment group of eight and a comparison group of nine, implemented a group program designed to resolve psychological career barriers over seven sessions, and applied no treatment to the comparison group. In an effort to examine the program's effects, the investigator conducted tests on psychological career barriers, self-efficacy in career decision-making, and self-determination in the pre- and post-test both in the treatment and comparison groups and examined the differences between them. The findings were as follows: first, the treatment group made a significant decrease to its psychological career barriers scores compared to the comparison group; second, the treatment group made a significant increase to its self-efficacy in career decision-making scores compared to the comparison group; and finally, the treatment group also made a significant increase to its self-determination scores compared to the comparison group with a significant enhancement. That is, the program was effective for lowering the psychological career barriers of university freshmen and improving their self-efficacy in career decision-making and self-determination. The study also discusses the utilization of its findings and future study.

As the size of venture firm's operating funds continues to increase, the scope of work of the investment jurisdiction is increasing dramatically as well. However, investment decisions vary widely, depending on the competence of the judges. This follow-up study recommends verifying the validity of the effectiveness of venture investments by validating the efficacy of assessing venture investment indexes. After verifying the assessment indexes for 100 venture firms, the study noted that the efficacy of the survey as a qualitative evaluation measure was approximately 85% hit, which can act as a yardstick for investment decisions. The results of this study can contribute toward the decision making power of venture companies in terms of investments.

In most of studies on market efficiency, the stability of risk measures and the normality of residuals unexplained by the pricing model are presumed. This paper re-examines stock splits, taking the possible violation of two assumptions into accounts. The results does not change the previous studies. But, the size of excess returns during the 2-week period before announcements decreases by 43%. The results also support that betas change around announcements and the serial autocorrelation of residuals is caused by events. Based on the results, the existing excess returns are most likely explained as a compensation to old shareholders for unwanted risk increases in their portfolio, or by uses of incorrect betas in testing models. In addition, the model suggested in the paper provides a measure for the speed of adjustment of the market to the new information arrival and the intensity of information contents.

Recently, automated business processing systems, so called workflow systems, have been studied. have been studied. even though each task has noticible duration inherently, most of previous models regard it as a simple finite automation where state transitions occur instantly. In this paper, we propose a modeling method for workflow each of whose component task has minimum processing time and due-date. Firstly we provide a priority function to choose the proper alternatives when tasks fail before their due-date. The priority function considers the time-relevant factor and the semantic compatibility level to decide the best alternative. secondly, we identify six different types of execution requirements for tasks with noticible durations. They are serial, parallel, simultaneous start simultaneous termination, interleaved and nested dependency. Note that previous models deal with only serial execution and parallel execution. Lastly, we also propose graph-based methods to detect logical conflicts in time constraint-based workflow specifications.

The purpose of this study is to explore key factors that influence the intention of continuous use of social network service users in the online environment. Since the intention of continuous use is one of the most critical factors in the profit model of social network service, the findings of this study should be useful to the SNS firms. This study use the personal and network aspects as major behavior intention of that influence user's attachment to a social network service. The results are summarized as follows. First, use motivation in self-determination have effects on emotional attachment, information sharing intention, loyalty. The world's most leading social network services now, the social network service has developed very fast as a kind of new online service. During the past few years, the number of Twitter's registered users around the world has already exceeded 170 million. Not only have the United Sates, many countries around the world have also been hit by the wave of SNS, including those in Korea. Since the intention of continuous use is one of the most critical factors in the profit model of social network service, the findings of this study should be useful to the SNS firms. We need to continue the study of social network.

The purpose of paper is to confirm the role of E-WOM(Electronic Worth of Mouth) in decision making of selecting the mobile application via smart-phone or tablet pc. Particularly i wished to confirm the effects of others' positive or negative reviews in purchasing(free downloading) mobile applications. To resolve these research questions, the secondary data or previous research were collected and arranged theoretically. From literature research, i made out the proposed model to explain the relationships between the variables, executed the operational definitions and 14 Hypotheses were established, collected the survey data of 228 mobile application users. Using the empirical test analysis, previous performances to confirm the construct validity and internal consistency and PLS(Partial Least Square) modelling method was executed. The test result showed that proposed relations of variables was empirically identified, therefore, i got the conclusion as followings; First, attributes of mobile application users' reviews have the effects positively to usefulness perception and expected performance. Second, it was significantly tested Usefulness of Online Review and Expected Performance. Second, Usefulness of Online Review, Source Credibility and Expected Performance have effect positively to Intention of Review Adoption.
