소프트웨어 기술의 생명주기가 점점 짧아지고 복잡해짐에 따라 그 기술을 이해하기가 힘들어 진다. 객체지향 기술채택을 더욱 잘 이해하는 것이 이 논문의 연구동기이다. 객체지향 기술이 전통적인 소프트웨어 프로세스 기술에 대한 새로운 패러다임이기 때문에 프로세스 중심의 구조지향 기술과 같은 기존의 소프트웨어 엔지니어링의 경험에 영향을 받을 수 있다. 본 연구의 목적은 이전의 구조지향 기술의 경험과 기술변화에 대한 개인적인 인식이 미국 기업체에서 객체지향 기술채택에 어떻게 영향을 미치는지를 실제로 조사하는데 있다. 2 X 2 유사 실험계획법이 사용되었다. 구조지향 방법을 사용한 경험과 새로운 기술에 대한 개인적 혁신정도(Personal Innovativeness)가 독립변수로, 객체지향 방법에 대한 사용편이성(Ease of Use)과 유용성(Usefulness)이 종속변수로 선정되었다. 데이터는 구조지향 방법과 객체지향 방법을 모두 사용한 경험이 있는 자료처리 및 관리협회(DPMA: Data Processing and Management Association)에 소속된 정보 시스템 전문가로부터 수집되었다. 연구결과는 구조지향 방법을 사용한 경험은 객체지향 방법의 사용편이성과 유용성에 영향을 주지만 개인적 혁신성은 영향을 주지 않는 것으로 나타났다. 과거의 구조지향 방법을 많이 사용하면 할수록 객체지향 방법의 사용편이성 값이 낮게 나타나기 때문에 이전 문헌에서 제시된 구조지향 방법의 객체지향 방법에 대한 지식간섭(Knowledge Interference) 현상이 있음을 실증적으로 보여주었다 마지막에는 본 연구의 한계점과 향후 연구에서 지식간섭을 줄일 수 있는 방안을 제시하였다.

This study examined the social discourse on consumer boycott and explored consumer experience using text mining of mass media and social media data and the in-depth interview. The result showed that the topics of online news related to the boycott included the causes of the boycott, the responses of each actor in the process of the boycott, and the effects of the boycott. In the result of the in-depth interviews, it was found that the boycott has been decentralized and the participants had the experience of exploring and verifying information on their own. In the boycott process, there were mixed experiences due to the absence of substitutes and the marketing influence, and positive experiences of expressing one's thoughts and strengthening beliefs through the boycott.

Background: This study was conducted to investigate the factors that influence sexual intercourse experience of university students in Korea. Methods: We selected 244 students who completed a questionnaire about general characteristics, sexual attitude, sexual intercourse experience, depression. It was analyzed by logistic regression using sexual attitude of university student, father, and mother as explanatory variables. Results: The results showed that sexual intercourse experience was more frequent in the respondents who were more open about sexual attitude, those whose mothers have more open mind to sexual attitude, and those who were less depressed. Conclusions: The sexual intercourse experience is important to affect the upcoming adult period in university students. This study suggests that it is necessary to develop systematically the sexual education program in university and society.

This study describes a set of user experience indicators developed for the evaluation of knowledge and information resource systems. The user experience perspectives had emerged as a new analysis standard in the field of information media and information service research. The study included a survey conducted to verify the derived experience factors and developed them as indicators. The survey data was gathered from 158 participants in the preliminary and 480 participants in the main study. The applied analysis techniques were descriptive statistics, the exploratory factor analysis, the confirmatory factor analysis, the correlation analysis, and the path analysis. The results introduced seven user experience factors, 37 detailed user experience factors, and 105 system perception factors as the final user experience indicators. The developed and verified indicators should measure the degree of user experience perceived by users of the knowledge and information resource system and conduct effective evaluations that reflect correlation rather than a simple comparison of each experience factor.

The period after the PhD has a huge impact on the careers of researcher from a researcher lifecycle perspective. This is a turning point which student receives guidance from professor and become an independent researcher. Furthermore, they learn to develop ideas for independent research, apply for grants and manage a project; they also form expert networks in related filed and publish papers to share their findings. This study focuses on the period between earning doctoral degree and being employed as a stable position in university. This study starts from a research questions that asks which factors of postdoctoral experience affect research output. In this study, the paper performance, especially co-authorship of paper, of postdoctoral researchers was investigated. The cumulative advantage theory and Matthew effect were employed to shed a light on this research question. The empirical work is based on the Survey & Analysis of National R&D program in Korea conducted by Korea Institute of S&T Evaluation and Planning (KISTEP). The correlations between the research output and characteristics of postdoctoral experience were verified. These results are expected to contribute as new empirical evidences on investigating knowledge transfer activities of new PhDs.

This study examines the labor market performance of graduates who had student loans. Compared to earlier studies, we extended analyses to all jobs that were experienced for more than 18 months after graduation. First, we found that students who had student loans earned 2.81% less at their first job compared to their counterparts without student loans. Second, the wage gap decreased over time, a reduction of 0.66%p due to labor market turnovers. Third, when we compared cumulated labor income, however, the amount for borrowers were continuously higher. This is because the job searching period of a borrower was shorter, despite relatively lower wages at the first job, and borrowers also made more frequent job turnovers, accompanying relatively more wage increases. These results suggest that the negative effects of college loans on earnings, reported in previous studies, may have exaggerated the negative impact to some extent of having loans. However, when we look at the quality of jobs beyond simply wages, the proportion of borrowers working at large companies as regular workers was consistently low. Given that job conditions at the earlier stages of one's career may lead to gaps over time, our findings call for more systematic investigations into the effects that student loans have on long-term labor performance.

This paper investigates the effects of prior entrepreneurial experience on new venture performance. Entrepreneurial experience has significant impacts on the early development processes of new ventures founded by experienced entrepreneurs. There are inconclusive results on the relationships between entrepreneurial experience and new venture performance. Based on the data of Korean new ventures, this paper empirically analyze these relationships of different entrepreneurial experience on new venture performance. Success experience has positive effects on employment but no effect on financial performance. Failure experience has negative relationships with financial performance as well as employment. There are moderating effect of firm age on the relationship of only failure experience with performance. Finally this paper suggests theoretical and practical implications of entrepreneurial experience on new ventures' development and performances.

The purpose of this study was to identify the moderated effects of multicultural contact experience on the relationship between social distance and multicultural acceptability among nursing students. The sample for this study consisted of 174 nursing students from four universities located in Korea. Data were analyzed by descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation and hierarchical multiple regression with SPSS/WIN 23.0. It was found that: (a) multicultural acceptability had a negative correlation with social distance(r=-.61, p<.001), whereas a positive correlation was observed with experience of multicultural contact(r=.24, p=.002); (b) the interaction effect by multicultural contact experience and social distance had a significant influence on the multicultural acceptability(${\beta}=-.18$, p=.003); (c) experience of multicultural contact moderated the relationship between social distance and multicultural acceptability(${\Delta}R^2=0.30$, p=.003). Results of the study suggest that the greater the experience of multicultural contact, the greater the negative effect of social distance on multicultural acceptability. Therefore, to increase the multicultural acceptability of nursing students, it is important to encourage the positive experiences of multicultural contact and thus reduce social distance.
