Even though, many enterprises began to use management information system, they were not able to attain remarkable outcome. Thus, a purpose for this research is to explore effect that characteristics of information technology and executive support have on its user's confrontation In order to verify this purpose, we selected Nong-hyup's CRM as an object for a proof of effect that characteristics of information technology and executive support have on its user's confrontation. According to this research's conclusion, characteristics of information systems have notable influence on user's confrontation, while executive support did not have significant influence on it. Yet, this research has its limits by considering characteristics of information technology and support from board of directors as only variables among many other possible reasons for user's confrontation. Thus, in the future, there should be another research that considers more various reasons for user's confrontation.

The energy of the building is influenced by the user 's activity due to the population, society, and economic characteristics of the building user. In order to obtain accurate energy information, the difference in the amount of energy consumption by the activities and characteristics of building users should be identified. The purpose of the study is to identify the difference in the amount of energy consumption by the user's activities in the same building, and to analyse the relationship between user's activities and demographic, social and economic characteristics. For research, energy simulation is performed based on actual user activity schedule. The results of the simulation were clustered by using K-Means clustering, a machine learning technique. As a result, four types of users were derived based on the amount of energy consumption. The more energy used in a cluster, the lower the user's income level and older. The longer a user's indoor activity times, the higher the energy use, and these activities relate to the user's characteristics. There is more than twice the difference between the group that uses the least energy consumption and the group that uses the most energy consumption.

지금까지 사용성과 관련된 웹 이용행위에 대한 예측이나 분석은 사용자의 인구통계학적 특성이나 사용정황의 특성만으로 주로 설명되어 왔다. 그러나 그러한 특성만이 행위를 유발하늑 요인으로 볼 수 있는지, 그렇지 않다면 어떠한 요인이 있으며 또한 그러한 요인들은 행위에 어떠한 특성을 유발할 것인지에 대한 의문으로 본 연구를 진행하였다. 이는 사용자 중심의 사용자인터페이스(UI)디자인에서 사용자 특성을 정의하는데 중요한 요소로 활용되었던 사용자정보(User Profile)를 사용에 있어서의 특정유형과의 상관관계를 포함하는 사용자정보(User Profile)로 확장시킴으로써 구체적인 사용자인터페이스(UI)디자인에 적용될 수 있도록 하기 위함이다. 연구내용은 첫째, 다양한 미디어에 따른 사용자를 이해하고 기존의 사용자 분류 방법을 고찰한다. 둘째, 웹 이용행태에 따른 사용자 분류를 위한 사용자 분류변수 및 변수 측정 척도를 마련하고 사례 연구를 통해 사용자 행위 특성을 추출하여 특성에 따른 사용자를 분류한다. 셋째, 실험을 통해 수집된 데이터를 바탕으로 분류된 사용자 집단의 사용자정보(User Profile)의 특성을 밝혀 사용자정보(User Profile)의 특성이 유발하는 행위의 요인을 규명하기 위해 행위 특성과 사용자정보(User Profile)의 특성을 맵핑시켰다. 이를 통해 사용자의 이용행태에 따른 특성이 사용자정보(User Profile)특성 중 사용자의 일반 정보와 사용정황 뿐 아니라 개인성향이나 매체 사용태도와 성격유형 등도 영향을 끼칠 수 있다는 가능성을 발견할 수 있었다. 실험 설계상의 몇 가지의 문제점들이 발견되었으나 이를 개선하고 보완한다면 좀 더 명확한 사용행위에 따른 사용자정보(User Profile)특성을 추출할 수 있을 것이다. 따라서 사용자정보(User Profile) 특성으로도 사용자의 행위 유형을 예측할 수 있어 사용자 분류를 활용한 사용자인터페이스(UI)디자인의 가능성을 확대시킬 수 있을 것이다.

The christian communities have been maintained and spreaded based on the great foundation of the holy bible. The printing and publishing technology made the holy bible popular at the end of the middle age. Namely, because of this remarkable development, the Bible have been became the best seller for centuries. Since the smart phone users have been growing, the number of people use the Bible Application have been increased. In this circumstance, the interface becomes a crucial element in the Age of Digital Media. Thus, developers have to regard the user's convenient. The user's characteristic is the important point to develop applications. This study is focusing on a particular using of the Bible, and how the using characteristic affects on application's UI. For this study, five bible applications reflecting particular using characteristics are chosen and compared in terms of function of services and elements of UI. Form this comparison and analysis, this study deduces the pattern of UI considering particular using characteristics such as patterns of reading, recording, sharing, and searching the bible. This study would be useful data for publications formed into applications and setting the UI which reflected the using characteristics be better user-centered.

Current computer viruses are one of the most serious problems in information age due to their potential demage and impact on use of information systems. To make the problem worse, virus development technology has been advanced rapidly, and use of network systems has expanded widely. Therefore computer viruses are much more complex and use of anti-virus software(AV S/W) is not enough to prrevent virus incidents. It implies that computer viruses as well as other information security matters are not solely a technical problem but also a managerial one. This study emphasized on computer virus controls from managerial perspective of information security and investigated factors influencing the effectiveness of computer virus controls. Organization's comprehensive security policies provide guidelines on how organization or individual can protect themselves from computer viruses. Especially, user's education has positive impact on user's security related characteristics. Based on the analysis of research model using structural equation modeling technique, security policies were influencing security controls and improving user's computer viruses related awareness. Also security controls had positive impact on security effectiveness. However, no significant relationship was found between user's security related characteristics and security effectiveness.

Nowadays, VCR(Video Cassette Recorder) has various functions, but users use to fail operating these function because of the complexity of operation. The process of operating VCR contains user's cognitive characteristics. It is necessary for designing it that we must identify a user's mental process in the behind of operational behaviors. This effort, as well as considering physical dimensions and layout, can make VCR easy to use. In this research, VCR remote controller are analyzed by the cognitive method and experiments. Three types of VCR remote controllers, cognitive VCR models and two non-cognitive(typical) VCR models, are adopted as experimental objects to test the validation of the suggested user's cognitive mode of VCR. As results, when VCR was operated by the cognitive prototype of remote controller, task completion time was reduced to 80.5%, and the number of errors was reduced to 96.8%.

This paper describes the differences of the information system's success factors to improve the end-user's performance according to the job characteristics. A modified model of DeLone and McLean's IS success model is proposed with the two added variables of the top management concern and the IS department support. The model is validated using data collected from a field study of 3872 users on 3 Korean companies. ANOVA, correlation analysis, and stepwise regression are used to test research hypotheses. The results of the study indicate the following implications. First the top management concern and the IS department support have the significant relation with the system usage and the user satisfaction. Second, the system quality has an influence on the user satisfaction more than on the system usage. And the information quality has an influence on the system usage more than on the user satisfaction. Third, the system usage has more relations to the user's performance in the logistics function and R&D function. The user satisfaction has more relations to the user's performance in the sales and the A/S function. Therefore information system strategy to increase the user's performance must be differentiated according to job characteristics.

This study proposed the Knowledge Base Building method reflecting the user's preferences based on the fuzzy set theory to develop information contents which support pedestrian's navigation. This research evaluated subject's preferences on the commercial spaces set to the hypothetical destination. Also it surveyed the causal relationship between the visual characteristics and the emotional characteristics to propose the methods of Navigation Knowledge Base (NKB). The NKB was composed by three elements; 1.the correlation model between emotional characteristics, 2.the causal relationship between visual characteristics and emotional characteristics, 3.the transformation model between visual characteristics and the physical characteristics.
