Purpose - This study is to integrate organizational factors into UCD process. For this research purpose, we investigated the organizational factors which influence people behaviors in the context of user-centred design practice(UCP). And this study presents organizational culture, organizational learning and change management as the organizational factors. Especially, this study is to investigate how change management influences the relationship between the organizational culture/learning and UCD performance. Research design, data, and methodology - Using the survey methodology with a questionnaire, this study distributed the questionnaire to the experienced 112 practitioners of user-centred design practice in 52 Korean small and medium companies. The organizations differed in range and size from medium-scale, which is under 100 of employees, and to small-scale, which is from 100 to 500. Results - Organizational culture and organizational learning have positive effects on user-centred design practice performance as expected. And change management strengthens the positive relationship between organizational learning and user-centred design practice performance but has no effect on the relationship between organizational culture and user-centred design practice performance. Conclusions - This is the first empirical study of investigating and demonstrating some key organizational factors' relationships and UCD performance of an organization, which will support to institutionalize UCD within an organization, providing theoretical foundations.

In order to manage organizational knowledge efficiently, Knowledge Management System(KMS) is considered as mandatory. This study aims at developing a KMS performance model to predict user satisfaction as well as KMS usage, considering the unique features of KMS. By analyzing 261 surveys with LISREL, we found that community of practice(CoP) characteristics - participation and interactivity among users - significantly affects KMS user satisfaction. This implies that the development of KMS should focus on facilitating users' interactivity and participations such as CoP activity, which differs from the general information system context. We also found that KMS usage is influenced by CoP interactivity, not by CoP participation, and that KMS usage as well as user satisfaction leads to user performance. Interpretations and implications of the findings are discussed.

The purpose of the paper is empirically to explore 'design manner', focusing on the designer's knowledge boundary on the designer-user interactions in the design process. This study conducts a field study and observed designer's interactions with actual users in a leading user-centered design firm over three months. The observations revealed how designers bring ideas about users into design without physically interacting with users during the design process. Based on Bourdieu's theory of practice and the concept of boundary objects, this study introduces the concept of 'design manner', by which designers incorporate user's ideas into the design process without actual involvement of users in the process. This paper contributes to the body of knowledge by introducing the design manner in-between designer's and user's knowledge boundaries and argue bridge between theoretical and actual designer-user interactions in the IS design process.

Expert systems represent the application of artificial intelligence research that is at least 10-15 years old. It may well take another 5-10 years before the present technology is exploited by industry. The objective of this paper is to show the applicability of Combined Hypertext-Expert System Techniques to the professionals working in the construction industry. Expert systems alone don't give the user any control over the system. Hypertext systems that focus only on displaying messages have the opposite problem. While they allow the user to control the system., the only control the system designer has is in setting up the hypertext links. Therefore the combination of these two techniques, offered by KnowledgePro, may bring us closer to real user-expert communication. The system developed in this work offers information on ACI Manual concerning various problem areas in concrete practice, consultation about mix design of concrete and guidance to identify types of cracks in concrete. Once the type of crack is identified through the rule-based knowledge, the system provides the user with remedial measures through the control of the user.

본 연구는 실증적 데이터의 검토 및 분석을 통해 이용자연구와 실용연구 분야의 특징을 발견하고, 이용자연구와 실용연구 분야의 융합 가능성을 논하고자 수행되었다. 이용자연구의 개척 및 확장 가능성을 살펴보기 위해, 실용연구 분야 중 UX 연구를 선택하여 비교하였고, 이용자연구 영역과 UX 영역의 주제어 및 분야별 중복도를 살펴보았다. 연구를 위해 국내 이용자연구 3,370개 논문과 국내 UX 연구 2,413개 논문, 국외 이용자연구 3,875개 논문과 국외 UX 연구 2,515개 논문을 수집하였고, 단순 출현빈도를 포함한 계량정보학적 분석방법을 이용하여 네트워크 맵핑 및 순위 선정, 시기별 비교분석을 수행하였다. 분석 결과 국내의 이용자연구와 UX 연구 중복도는 국외보다 낮은 편이었고, 분야 간 협업의 활발성이 중복도와 연관이 있다고 해석할 수 있었다. 시기별 분석을 통해 이용자연구와 UX 연구간 중복되는 키워드가 점차 증가하고 있음을 발견하였기에, 향후 이용자연구와 실용연구 분야 간의 융합이 활발히 일어날 가능성을 엿볼 수 있었다.

The purpose of the study is to establish sustainability evaluation items that can be applied to enhance clothing sustainability practice. The sustainability evaluation items related to clothing by product category, use, and disposal were derived through literature review. In order to evaluate the validity of the derived evaluation items, preliminary survey and two questionnaires were conducted for experts, and the importance and the possibility of change were measured. As a result, 39 evaluation items were constructed. Among the 39 evaluation items, 26 items related to the use and disposal were evaluated for 10 weeks in the 20s and 30s female consumers in terms of practice. The results of the study are as follows: First, items that have a high degree of importance and possibility of change are the items that can minimize resource saving, recycling, and the emission of harmful substances. Second, the participants' perceptions, attitudes, and outcomes of practicing the evaluation items of the use and disposal phase were proved to be positively affected, and the possibility of reducing resource saving and environmental impacts was proved. The clothing sustainability practice played a positive and developmental role in real life, while changing from small things to pursuing newness. The vagueness of sustainability was changed to specific perceptions and behaviors through the practice of the evaluation items.

Growth of pigs is influenced by many factors. To assist pig producers in the evaluation of alternative feeding and management strategies growth models have been developed. In the Netherlands the Technical Model Pigfeeding (TMV) is developed. This model predicts the influence of feed intake, feed composition, genotype, sex and climate on growth, body composition, gross margin and mineral excretion of healthy growing/finishing pigs. The purpose of TMV is to support information services, feed companies, researchers and students. In addition to providing accurate predictions, a model should also be user-friendly and wishes of the user should be taken into account to stimulate application of the model in practice. In this paper, the theoretical background of TMV and a methodology to stimulate application of models in practice will be described.

Now these days, many technical concepts and tools have been developed in the cryptographic field. Most digital signature schemes used in practice, such as RSA or DSA, have an important role in information privacy and secure authentication for perfect user. A clearly advantage of such schemes over with security proven relative to such common cryptographic assumptions, is their efficiency: as a result of their relative weak requirements regarding computation, bandwidth and storage, these scheme have so far beaten proven secure schemes in practice. Our aim is to contribute to bridge the gap that exists between the theory and practice of digital signature schemes. In this paper we present a digital signature that ensures information privacy. More precisely, under an appropriate assumption about RSA, the scheme is proven to be existentially forgeable under adaptively chosen message attacks. This mechanism can be applied to smart cards or E-Wallet for maintaining secure authentication for user’s information privacy.
