Anthropometric data of the hand is one of the important issues for the product design related with hand and manual operation in terms of user-centered design. Direct measurement, which traditionally uses anthropometric measuring tool, has a few disadvantages in cumulation of measuring time, possible errors in raw data, doubtful reliability between inspectors. Newly introduced 3D scanning technology overcomes those disadvantages; however, another disadvantages, such as, hight cost and immovability, have been introduced. In this study, photogrammetric approach was introduced for the measurement of anthropometric data in hand. In order to minimize the possibility of error during direct and indirect measurement, a simulated object was used and effectiveness of photogrametric measurement was confirmed for the collection of anthropometric data in hand.

A study was conducted to develop user-centered kitchen furniture and workspace to reduce fatigue and to prevent housewives's disorders such as low back pain and musculoskeletal disorders from housekeeping activities. A questionnaire survey and interview were performed on 150 households those live in 32Pyung-type($105m^2$) apartment in Seoul vicinity. Also actual housekeeping activities for 24 hours were video-taped for further motion analysis. Results of the study revealed that housewives complained the inconvenience and small size of storage space, and worksurface height as the most important problems to be considered for redesign. And they responded, if feasible, sitting is preferred over standing while they are working. After adapting a sit/stand chair in the kitchen, a physiological experiment measuring heart rate(HR) and oxygen consumption($VO_2$) as response variables was conducted to examine the effects of sit/stand chair in reducing physiological demand during housekeeping activities. The results showed that working on sit/stand chair reduced energy expenditures by maximum of 30% and 31.0% in terms of HR and $VO_2$, respectively. Also rearrangement of kitchen structure based on motion analysis showed that walking distance during daily housekeeping activities can be reduced by 5.5% on the average. Hence, it is concluded that adapting a sit/stand chair in the kitchen could reduce fatigue and occupational disorders of housewives from extended housekeeping activities.

The purpose of this study is to examine the features of Internet bookshops in order to suggest the most effective website model for them. Seven Internet bookshop websites are analyzed. The evaluating criteria includes: interface layout, contents, function aspects. The results show that a suggested model should include various aspects: 1) user-centered menu structure, 2) effective search methodlsubject directory, and 3) various and good quality review.

The ecosystem of the Library has been radically changing in the advent of ubiquitous information service technology. We are already aware of the digital library due to popularizing digital information resources and we are impressed with Library 2.0 and Social Semantic Digital Library of user-centered, service-oriented library. We summarize the ultimate goal of the evolution of library systems as knowledge services and propose a logical model of library system for the realization of knowledge services. This local model can be applied for a library framework to harmonize the diverse knowledge resources, active users with participation and collaboration, the innovation of library business and ubiquitous information service technologies to achieve the missions of library in knowledge-intensive society.

Library and information science(LIS) has been focused on the issues of information poverty and barriers and their relations, mainly in terms of current information users. However, potential users usually out of sight in library and information services undoubtedly are to be developed as legitimate clientele. In this regard, this paper attempts to shed light on some factors related to the methodological underpinnings of LIS. Ethnographic research is particularly highlighted. Since the mid 1980s, as full-fledged research of analyzing the contingencies of information use as situated in particular times and places. md using that analysis to inform user-centered information systems design LIS researchers and practitioners have been exploring possible use of ethnographic approaches, especially in studies investigating information world of the socially marginalized. This Paper addresses issues in conducting ethnographic studies in the discipline. This paper also discusses the experiences in conducting ethnographic based research md how the results of their studies may be or have been useful in improving information services fir specific populations.

This Design research is a design of rescue equipment combined with beach garbage can for prompt rescue at the time of the accident in water. As a usual, it is used as garbage can hanging a garbage bag on the holders located in both sides, and it can be used to rescue drowning men promptly taking out a rescue tube located inside of the equipment at the time of the accident in water. Support is consisted of beach one, wall-hanging one and pipe one, and it could be installed to match the situation because it can be combined with all main frames. As a usual, it is used as garbage can in seaside, but it can be used to rescue drowning men promptly taking out a rescue tube after pulling the handle located in front of main frame at the time of the accident in water, and it can be used to pull drowning men out of the water because rope is kept in rescue tube.

The users need the communication that interaction is possible in digital communication environment. It is necessity to develop the Interactive Character that various emotional expression was possible while a user-centered emotional display tool was necessary. It is a fundamental research that is going to develop the Interactive Character that individualized emotional expression is possible. In other words, I have the purpose that is going to show the aromaticness of the technology development to express feelings. Therefore, I am going to analyze whether no matter how much technology to express feelings mainly on a face expression is incarnated through an example. And, I am going to show the development direction of the Interactive Character as an emotional display tool through this.

Many users have made the most often use of the SAS system in statistical data analysis all over the world. But it is difficult to use the grand procedures and language of the SAS system. Therefore the side of program development has changed in the graphic-oriented and menu-centered way like SASj ASSIST, SASjINSICHT after a version 6.08 turned into the Window environment. A biplots is a multivariate data analysis technique that graphically describes both relationships among the multidimensional observations and relationships among the variables. But there were not the procedure and graphic interface for a biplots algorithm in the SAS system. In this paper, there are two objects. First, we supply users with the convenience of the environment of CLI, which is constructed with SASj AF and SCL, to solve the problem that we have programed a biplots algorithm with the SASjIML one by one. Second, we reflect the current of the Information Age which means the spread of various kinds of system construction to extract useful information from data with the help of the development of hardware and software.

In the rapidly changing science and technology environment, an in-depth understanding of users of STEM information is an essential factor in designing a user-centered information system. The purpose of this study is to investigate and analyze in-depth the behaviors and needs of users who use STEM information. In this study, the needs of users for STEM information and STEM information sites are dealt with in depth using the FGI qualitative method. In addition, it includes the analysis results of grouping of similar sites according to various aspects of use of STEM information sites. As a result of grouping similar sites based on awareness and level of use,, they were grouped by domestic-international, paid-free, integrated-specific fields. As a result of grouping similar sites according to the purpose of use, they were grouped by domestic and international papers, research reports, and patents. As a result of grouping similar sites according to usage attributes, they were grouped by diversity, reliability, and specialization. As for the positions of similar sites perceived by users, Science Direct and PubMed showed high specialization and high quality, Google Scholar showed integration and popularity, and RISS showed four attributes evenly. Suggestions for information system design are discussed.
