This study is to examine the factors that influence purchasing behavior and decision-making when consumers buy goods through mobile shopping, define purchasing decision-making with the steps of problem recognition, information search, alternative assessment, and purchasing behavior to understand mobile consumer behavior, and investigate how the factors of each step play roles and influence consumers' purchasing decision-making through positive analysis to figure out consumer purchasing behavior in mobile shopping. The study results, First, the user characteristics of information search influence flow. Second, in the relations between the user characteristics in the step of information search and perceived risk in alternative assessment, if recognition on gains is higher, perceived risk for time loss gets lower, and when the level of skills is higher, perceived risk gets higher, and it has been partly adopted that innovativeness does not influence risk perception. Third, in the relations between flow experience and purchasing intention, it has been found to be partially significant that remote presence and challenge do not influence purchasing intention but do influence excitement, attention concentration, and control and also do influence perceived risk and purchasing intention. Fourth, according to the results of analyzing the difference of consumer purchasing behavior by the types of involvement, practical involvement and sensual involvement, user characteristics and flow, and perceived risk differ by the types of products in terms of the search process, thereby changing purchasing intention. Lastly, the significance and limitations of this study was discussed.

This research was conducted in an attempt to understand changes and growths of the self in on-line game world. Q methodology was used to investigate players in Mabinogi, which is an on-line game(MMORPG). Based on 57 behavior statements, Players distributed their changing experiences from when they were novices in on-line game world to the current state. In early start phase, they recognized that on-line game world was different from the reality. And they perceived their experiences in on-line game as separated from the real ones. However, as they spend more time in on-line game world, they began to realized that on-line game world is as real as the world because they function as an individual living in a society in both the game and the real world. They felt and learned that in on-line game life, they also need to follow the rules and order. In addition, trust and politeness were essential in order to live with other players. As time passed, the players realized that on-line game experiences have the same meanings and values as the real life ones. 3 types of self-changing patterns were found : Achievement change, Control change, and Relation change. The behavior patterns of the 3 types were then compared to Identify similarities and differences amongst them in psychological meanings and values in the on-line game life. This result illustrates that on-line game world can be defined as new behavioral setting or developmental context established by digital technology. In this new setting, people can experiment and understand their behavior patterns and also experience changes and growths of the self.

As the use of recommended agents has become more active, the "Explain Facilities" is drawing attention as a way to solve the black-box problem that could not explain internal logic to users. This study wants to look at how the description Method and Detail affects to user experience. The Explanation method was divided into 'why the agent did a particular action' and 'why not do a particular action' and the detail condition were divided into 'high or low'. Studies have found that 'why method' have a positive effect on users' transparency, trust, satisfaction, and behavioral intention to use, and 'high detail condition' higher the user' Psychological reactance. In addition, it was found that the explanation methods and detail influenced the 'Explanation' perception through interaction and tended to affect satisfaction and intention to adopt recommendation. This study suggested that careful attention is needed to determine the method and detail of the Explanation facilities in the context of the recommended agent, based on the research findings that it affects the user experience through the interaction of the method and detail.

Recently, financial companies are promoting chatbot services in line with the reduction of branches and the expansion of non-face-to-face services. However, it is difficult to expand the chatbot services at once in the presence of technical limitations and constraints of internal and external environment. Therefore, it is necessary to analyze the various situations of chatbot service to preemptively identify problems that can occur in stages and seek solutions. This study conducted interviews with 12 field practitioners and researchers to examine the intentions and behaviors of financial chatbot service users and interpreted them using TPB. The study revealed the characteristics of 'feelings and attitudes' such as convenience or inconvenience from the chatbot experience, 'subjective norms' such as herd behavior or the yearning for empathy of others, and 'behavioral control' according to the recognition of difficulty or convenience of chatbot use process. This study shows that this characteristic can affect the intention and actual behavior of users to use chatbot service continuously. In the future research, it is necessary to empirically study specific intentions and influence factors for actual users.

상황 인식(Context-Aware) 시스템은 현재 자신이 처한 상황 정보를 인식하여 그에 맞는 행동을 결정하고 그 결과에 따라 동작하는 시스템을 일컫는다. 이러한 상황 인식 시스템은, 유비쿼터스 컴퓨팅을 비롯해 특정 작업을 수행하기 위해 사용자로부터 주어지는 입력 값 이외의 환경 정보를 필요로 하는 분야에서 주로 사용된다. 이때 시스템이 인지하는 상황은 자신의 작업을 수행하기 위해 필요한 환경 정보로 구성되어 있다. 가령 온도조절 서비스를 담당하는 에이전트가 있다고 할 때, 이 에이전트는 사용자의 요청 온도를 맞춰주기 위해 현재 실내 온도를 측정할 수 있어야 한다. 그래야 요청 온도에 도달했을 때, 동작을 멈출 수 있기 때문이다. 이처럼 각 에이전트가 자신이 필요로 하는 정보를 인지하고 그에 따라 작업을 수행할 때, 다일 에이전트 혼자 그 공간에 존재한다면, 자신이 필요한 정보만을 인지하는 것으로 적절한 작업 수행을 기대할 수 있지만. 둘 이상의 에이전트가 동일 공간에 존재하고, 각 에이전트의 작업 과정이 서로의 수해 과정에 영향을 미칠 가능성 즉, 에이전트 사이의 충돌 발생 가능성이 존재한다. 이미 오디오가 동작하고 있는 방안에서 TV를 작동시키게 된다면, 음악을 들을 수도, TV를 볼 수도 없는 상황이 발생한다. 이에 본 논문에서는 동일 공간에 존재하는 상황 인식 에이전트들 사이에 발생하는 충돌을 해결하기 위한 방법을 제안한다.

Many studies in the field of information security reveal the need to increase awareness. However, although awareness of information security has been raised to a considerable extent, actual security behavior has been shown to fall short of that. Therefore, we wanted to identify the role of psychological factors in making information security decisions by conducting a experimental study. The results show that there are differences in perception of information security risks according to the probabilistic distance and the degree of relative optimism due to social distance. In relation to their relative optimism and intention of information security, they reduced the level of perceived risk compared to those close to them and found that their influence varied according to their probabilistic distance. This study has made valuable attempt in terms of methodology and it is meaningful that the psychological factor is taken into consideration for the information protection behavior, so that the range of relative optimism that actually affects the perception of risk is narrowed. It is expected to contribute to the improvement of information security level of information technology users and protection of information assets by empirically identifying necessity of various approaches to decision making process for information security.

Users connect to game server for considerably many hours and perform their roles in MMORPG(Massively Multiplayer Online Role Playing Game), users' immersion degree is very higher than other games, have known affluent contents make users play various roles in game world. However, although contents of games are improved quite much, MMORPG remains still boring game. It is because that the NPC (Non Player Character)' behavior patterns that are the most important elements to make games fun are so simple. So, in this paper we proposed a method to create NPC that react in player's inclination by implanting personality and emotion to NPC.
