The lack of an understanding of the characteristics of a specific user group in computer-based information systems in libraries hinders library and information science professionals in grasping users' needs and making the best decisions when designing, acquiring, and managing information systems. The objective of this study was to provide information on the characteristics of specific user groups such as male ＆ female student groups. undergraduate ＆ graduate ones, Sciences and Humanities majored ones etc. This study also provides system developers (vendor) and adopters with users' needs and the merits or demerits of a specific system on the basis of students' evaluation. For the purpose, questionnaire was prepared and administered to Korean college students in the city of Taegu, Korea and adjacent area. One hundred and seventeen usable questionnaires were obtained and analyzed. These were analyzed using descriptive, inferential statistics. and SPSS software. The major findings of this study are: (1) Gender of the students affects the preference for the type of OPAC system selected more than that of academic level of study, age, and academic major; (2) The domestic in-house OPAC systems in Korea affect the user preference of system much more than that of foreign package ones; (3) System designers should prepare and use professional terms or abbreviations for system users more carefully, and explain them in detail; (4) Most of users preferred package OPAC systems to in-house ones, and preferred GUI systems to Telnet-based ones. Also, there was a significant difference between them. Conclusions are drawn from the findings in this paper, and recommendations are proposed when designing, adopting, or managing a new system. Topics for future studies on the characteristics of OPAC systems and their user are also suggested.

The traditional broadcasting services over terrestrial, satellite and cable media have been unidirectional mass media regardless of TV viewer's preferences. Recently ich media streaming has become possible via the broadb and networks. Furthermore, since bidirectional communication is possible, personalcasting such as personalized streaming services has been emerging by taking into account the user's preference on content genres, viewing times and actors/actresses etc. Accordingly, personal media becomes an important means for content provision service in addition to the traditional broadcasting service as mass media. In this paper, we introduce a user profile reasoning method for target advertisement which is considered an important application in personalcasting service. The proposed user profile reasoning method predicts an unknown TV viewer's gender and ages by analyzing TV Viewing history data. Based on the estimated user's gender and ages, a target advertisement is provided with TV Anytime metadata. A proposed target advertisement system is developed based on the user profile reasoning and the target advertisement selection method. To show the effectiveness of our proposed methods, we present a plenty of experimental results by using realistic TV viewing history data.

The purpose of this study is to contribute the use of special taxi for the transportation vulnerable such as elderly and pregnant woman in terms of improving transportation mobility and extending social participation. We analyzed the DB users of STS system operating in Suwon, and surveyed the preference statement. Specifically, we have built transportation mode choice models for the elderly and pregnant woman, and then we drew the activating STS plan by comparing influence factors for each model. Based on the results of the study, 23% of STS user was the elderly people and pregnant women, 31% of user was for hospital passage purpose, and short-haul passage within 2 ~ 5km was 70% level of the passage. According to preference survey results between STS and Bus, fare was the highest impact factor in the mode choices for the elderly, and the participants who are older and car owners have been found to prefer the special taxi. For the pregnant woman, travel time and fare were the main influence factors of choices, and it was discovered that they preferred the special taxi when they are car owners and trips was frequented. Also, if the fare of special taxi is about 70% of the regular taxi fare, The share rates of Special Taxi comparing to bus for the elderly and pregnant woman are analyzed to be 51.1% and 63.6% each. Therefore, the adjustment of the fare would be effective to encourage the use of the special taxi. The results of this study can be used as a basis for establishing the rational fare structure of the special taxi.

With the increase in use of the computer, the VCT syndrome has occured as a new socialJhea/health problem. ErgonomicaI design standards are a for the users to reduce stress and poor physical posture in the human body. In this study. we have suggested design dimensions recommended from previous studies. We also have reviewed users' preference dimenision, and analyzed differences between users' preference dimenision. and the previous design aiteria to verify physical appropriateness. We analyzed how each design dimension was reached and affected the tunan body by objective EMG evaluation. and subjective evaluation of physical discomfort and oorrIort. We have found that keyboard height is very important in a workstation. If the elbow's height is lower than the keyboard's height. it effedS the hand and wrist. If higher, it brings fatigue to the shoulder and neck. As a result of this experiment. we suggested that the height of a keyboard desk for Koreans be 660mm for the fixed type and 540-774mm for the adjustable type. Also other design reoommendations were suggested in the thesis. In ooncIusion, our research will be very important in the database because it provides adjustable ranges to fit user's body types in the various design flekIs.

It can be expected, recently, that the traffic congestion grows worse because the 48% of passenger cars are concentrated in the metropolitan area. However, there is an enforcement regulation that must limit onsite parking lot establishment in some downtown, so it is forecasted that parking lot supply is insufficient. Therefore, this study concentrate upon the subject that solves the problem which drivers are difficult to find parking lots because of increasing demand for parking. This study includes the concept about walking distance because the choice of parking lots is happened within walking distance. The algorithm of this study applies to toy-network, and then this study analyze the result of toy-network. It is proper to consider user's preference because the patterns of choice are different. Moreover, this study suggests the vision that will can offer drivers more correct information by real time information sharing in course of ubiquitous age.

Planning railferry system in Korea-China trade routes, the overall evaluation and customer response are coming under spotlight in a preference and feasibility perspective. Persistent Railferry issue has been an area of study for the last decade. But until now, a surveyor or the evaluation from the actual users were exceptionally rate. Consequently, there is a need for a more detailed study into the practical issues such as customer response and railferry demand etc. Using a questionnaire survey from actual users, this paper examines the underlying evaluation on the Railferry system both in terms of demand and preference. The research questions were analyzed on data collected from almost 150 users in Korea. A range of arguments and expected problems were summarized. The results in general find a negative relationship between railferry preference and respondents' work experience. Findings in the reasons respondents are objecting the new railferry system, the suitable cargo type of railferry, and the possible barriers to introduce the system are discussed. Nonetheless further researches into railferry system as a possible alternative for Korea-China-Japan corridor should be followed in the near future.

This study focused on seeking out the user-oriented design criteria for the planning of the SCS. The survey was carried out with a structured questionnaire including sketch map from Aug. 13, 2001 to Sept. 14, 2001. The subjects were housewives who's living in Haeuondae of Busan, Korea. Total number of 650 questionnaires were collected and analyzed. Especially 439 cases among them were used for analysis of mental map. The SPSS PC＋ was used for the analysis of data. The results of this study are as follows : First, as to the users' behavior for the SCSs, there is a difference in the location of residents' activities by contents of them. And, the range of these locations categorized according to levels of spacial cognition for neighborhoods. Second, as to the analysis of the SCS through a mental maps, it was shown that the residents' pathway and the residents' location are main variables to be considered in the SCS planning. The preferred location of SCS is organized according to the character of the SCS; the one for most residents, is located the surrounding of main enterance or the center of the housing complex, and the one the neighbors living in the same or the near building is located in area of the block of resident buildings. Third, as the results of residents' needs analysis, the SCS has the meaning of community facilities. And there is a difference in the degree of necessity and in the preferred location according to character of the SCS. In detal, for the indoor SCS of a resident building, there is a difference in the preferred location according to the kinds of each SCS. And for the outdoor SCS, it is necessary to divide the planning zone of the SCS into 3 steps(the resident building, the block of resident buildings, and the housing complex).

A significant number of studies have been conducted on user perceptions of archive and record contents for the National Archives of Korea (NAK) and local record centers in the field of archives and records management in Korea. Yet, there has not been such a research on the use of digital archive contents designed for contents creation. Accordingly, this study investigated user perceptions of the use of the contents on the Korea Creative Content Agency (KOCCA)'s Culturing archive designed for creation purposes. A survey was conducted, examining the user's degree of interests, the expected user preference of the use and the expected extent of help by the contents of the archive. For the analyses of the survey data, this study performed one-way ANOVA for the comparative analyses of the means related to the subjects' general characteristics and the perceptions, along with cross-tabulation analyses for the association among the same items and nominal variables related to perceptions. On the basis of these analyses, this study suggests the following: ① to supplement the contents of the archive; ② to design customized interfaces and to enhance the readability; ③ to reinforce site PRs for large portal sites and creators' groups.

Today, the number of elderly drivers who use navigation is increasing with the growing number of elderly drivers. The purpose of this study is to provide guidelines on the interface of car navigation for elderly users. To extract significant factors which were distinguished between young and elderly users, both young and elderly users executed the driving test by installing two car navigation alternatives. The analysis was conducted through t-test. The results show that significantly different factors were the number and the meaning of the menu items in the initial screen, the location and the meaning of the menu icons in the map screen, the ease of search of the menu and the text size in the menu screen. Improvements for the factors of the initial screen and map screen were made with reference to ergonomic guidelines, and suggested through experiments comparing design alternatives for the menu screen. Design alternatives were made through a combination of investigative variables, and the analysis was conducted through ANOVA. The results show that Alternative 7 (the location of the tab was placed at the bottom, menu representation was done with the text font size of 18pt and the location of menu navigation icons was shown at the upper left) was preferred in terms of user's preference and the execution time. So if the suggested menu for elderly users are added to the existing design, both users will satisfy their desires. The guidelines suggested in this study will help the designer of car navigation take elderly users into consideration.
