The increased investment in technological innovations makes the investigation of factors affecting technology adoption more interesting. Several perspectives have been proposed to explain the determinants of information technology adoption. While the traditional innovation diffusion research streams try to explain and predict adoption behavior with the adopter's perceptions about the characteristics of the innovation itself, critical mass theorists argue that adoption behavior as a collective action is based on what their business partners are doing and whether there exists enough critical mass to justify the investment. Drawing on theses two perspectives, this study investigates the decision criteria in the adoption of information technology as innovation and factors affecting the decision criteria. The survey results reveal that the adoption behavior is affected both by innovation characteristics and by critical mass's activity. Correlation analysis, t-test, and stepwise regression models also show that as the environmental uncertainty is getting higher, adoption decision is affected more by what others are doing, and that highly competitive organizations seem to play the role of critical mass.

While prior work has conducted individuals' password security behavior, there is a relatively neglect to examine individuals' affect and feelings of password fatigue in password change context. Therefore, this study explicated individuals' affective response to the feelings of password fatigue by drawing on several theoretical lens. Survey data collected from 267 users were used to test the model using partial least square analysis. This study found that feelings of password fatigue positively affected the negative password fatigue-induced affect, and also both the feelings of password fatigue and the negative password fatigue-induced affect were negatively related to attitude toward changing passwords, which in turn, leads to the intention to change passwords. Furthermore, this study found that shadow work recognition negatively moderated the relationship between attitude and behavioral intention. This study could offer a new theoretical perspective to understand an individual's security behavior and provide empirical evidences for practitioners in charge of IT security in organizations.

This review aims to synthesize social network theories by drawing on the importance of social network perspectives in understanding knowledge management with technology in organizations. I provide an overview of prior social network research with the following core ideas: the primacy of relations between organizational actors, the utility of actors' embeddedness in social fields, the social utility of network connections, and the structural patterning of social life. On top of that, I summarize critical social perspectives (the social capital theory, the structural hole theory, the embeddedness perspective, the social exchange theory, the organizational learning theory, and the innovation diffusion theory) to suggest potential research questions for future studies in social network research in the knowledge management discipline.

Due to the differences between and distinct consumer perceptions of domestic and cross-border e-commerce (CBEC), e-consumer misconduct, which we call "cunning behavior," has emerged. This study examines cunning behavior in CBEC and compares e-consumer perceptions about environmental factors and their own personal traits using a vignette experiment and survey. The vignettes of this study were developed for three situations: illegal, deviant, and unethical behavior. Drawing on vignettes, we collected survey data and then examined the research model using the analysis of moment structure statistical tool. The results show that perceived benefit and past experience with CBEC are strong triggers for cunning behavior, while the ability to exercise self-control restrains this behavior. This study provides an understanding of why cunning behavior occurs in the CBEC context and describes different cunning behavior types.

Previous studies show that students have difficulties in understanding and using molecular visualization tools. This study focuses on the ways in which first year chemistry undergraduates use ball-and-stick molecular models to explain the concept of addition reaction and the difficulties that they face using the models. Video recordings of interviews with undergraduates manipulating ball-and-stick models to solve problems related to reaction mechanisms are analysed to determine if they are able to elucidate their understanding with use of models. The results showed that students have difficulties with viewing the ball-and-stick models from the proper perspective and understanding the relationship between the various structures that they have created using the models. They also find the use of ball-and-stick models tedious and prefer drawing molecular structures on paper to explain their ideas. Implications for the teaching using ball-and-stick molecular models are discussed.

I investigated a method for drawing the star chart in the planisphere Cheonsang-yeolcha-bunyajido. The outline of the star chart can be constructed by considering the astronomical information given in the planisphere alone and the drawing method described in Xin-Tangshu; further the chart can be completed by using additional information on the shape and linking method of asterisms out of an inherited star chart. The circles of perpetual visibility, the equator, and the circle of perpetual invisibility are concentric, and their common center locates the Tianshu-xing, which was defined to be a pole star in the Han dynasty. The radius of the circle of perpetual visibility was modified in accordance with the latitude of Seoul, whereas the other circles were drawn for the latitude of $35^{\circ}$, which had been the reference latitude in ancient Chinese astronomy. The ecliptic was drawn as an exact circle by parallel transference of the equator circle to fix the location of the equinoxes at the positions recorded in the epitaph of the planisphere. The positions of equinoxes originated from the Han dynasty. The 365 ticks around the boundary of the circle of perpetual invisibility were possibly drawn by segmenting the circumference with an arc length instead of a chord length with the ratio of the circumference of a circle to its diameter as accurate as 3.14 presumed. The 12 equatorial sectors were drawn on the boundary of the star-chart in accordance with the beginning and ending lodge angles given in the epitaph that originated from the Han dynasty. The determinative lines for the 28 lunar lodges were drawn to intersect their determinative stars, but seven determinative stars are deviated. According to the treatises of the Tang dynasty, these anomalies were inherited from charts of the period earlier than the Tang dynasty. Thus, the star chart in Cheonsang-yeolcha-bunyajido preserves the old tradition that had existed before the present Chinese tradition reformed in approximately 700 CE. In conclusion, the star chart in Cheonsang-yeolcha-bunyajido shows the sky of the former Han dynasty with the equator modified to the latitude of Seoul.

상업용 소프트웨어에 견줄만한 수준의 오픈소스 소프트웨어들이 등장함으로 인하여, 오픈소스 (정보시스템 개발) 프로젝트에 대한 학계의 관심이 고조되고 있는 가운데, 오픈소스 프로젝트의 관리경영측면에 관한 연구들은 막상 찾아보기 쉽지 않은 상황이다. 이러한 현실에서 본 논문은 기존의 전통적인 정보시스템 개발관리에 적용되는 경영관리 이론들이 오픈소스 프로젝트에도 그대로 적용될 수 있는 지를 살펴보고자 하는 학문적 관심에서 출발하여 사례연구 방법을 적용하여 행위통제의 관점에서 오픈소스 프로젝트들이 어떻게 관리되고 있는가 라는 문제를 연구하였다. 자료분석과 해석을 통해, 본 연구는 구체적인 사례들에 있어서 개별적인 차이들은 존재하지만, 전반적으로 오픈소스 프로젝트 관리에 있어 다양한 형태들의 행위통제가 이루어지고 있다는 사실을 확인하였다. 이러한 발견은 오픈 소스 프로젝트는 그 특성상 행위통제가 적용되기 어렵다고 보는 기존 일부 연구자들의 주장과 배치되는 내용이다. 오픈소스 프로젝트 관리에 관한 보다 더 포괄적인 학문적 이해를 위해서는 향후 결과통제와 자기통제까지 포함하는 보다 더 확대된 연구가 필요할 것으로 보인다.
