In order to understand interaction between building users' occupant performance and building maintenance performance of maintenance management personnel, actual data from maintenance activities of buildings were analyzed. Also, using building defect customer complaint data reported by building user, satisfaction data on building maintenance services of building users and service response time of maintenance management personnel, a method for evaluating interaction of buildings with the same purpose and same size was proposed. Throughout analysis, average number of occurrences per unit area per year for the mechanical complaints in complex building were presented. In addition, using building users' satisfaction with facility management services, attitude of responding to business obstacles, number of occurrences per unit area per year of mechanical complaints and complaint processing speed, interaction was comprehensively identified and compared.

The purpose of this study is to present a management improvement suggestion for better user satisfaction. For this, this research looked into the current issues of public libraries with literature review. Then a survey of eight hundred users in four libraries in Y-gu, D Metropolitan City was conducted to figure out users' needs. As a result, the purpose of use, visit frequency and programs demanded are turned out to show statistically significant differences. Based on this result, finally, this study suggests an advisable management direction for public libraries and practical ways to improve user satisfaction.

The web might be today's most widely-used technology and over the past few years, the web has evolved through various phases and is a mature technology Specially, the web interface technologies, such as folksonomy, tagging, RSS have been developed and changed with respect to user-friendly. In this paper, we should apply to not only the general structure scheme but also the tagging technology for POI information management and develop POIM(POI Management tool)for it. For POI service with user-friendly, the user can available to define, modify, and delete for a specific POI object based on XML by using POIM and then these should be saved on GML.

In this paper, we analyze the performance benefits of broadband ATM networks when the call control and management flows are separated from user data flows. The virtual path tunneling concept for control and management flows are applied to the same physical ATM networks. The behaviors of channel throughput and transfer delay are analyzed. It results that the proposed virtual short-cut paths can maintain the network being stable with acceptable bandwidth. They are very useful to provide the stable control and management capabilities for Internet and mobile applications in the broadband ATM networks. In our numerical results, the effective throughputs of the proposed virtual shout-ut channel are about three times than those of end-to-end user data channels with hop distances of 10, and about two times than those with hop distance of 5 when the link blocking probability increases to 0.1. It concludes that the effective channel bandwidth are greatly reduced down while physical links are not stable and user traffic flows are occasionally overflowed.

The level of competition has reached the limits in cellular phone market and the cellular phone manufacture companies started to focus their solution in user interface. Design issues with controllability led the development and renovation of such products to the use of the touch-screen phone. Depending upon the readability, technical advances, portability and controllability, user satisfaction of touch-screen phones could vary significantly. In this research, the controllability was dealt in regard to various grip postures, in order to improve menu layout which fits for using the thumbs of both hands and a thumbs of single hand. Regression models are found to the suggest the location of buttons on the screen by redesigning the menu layout, it is expected to improve both controllability and satisfaction of the user. This result can be applicable not only to mobile phone design, but also to the design of various hand-held devices using a touch screen.

This study aims to systematically develop a usability evaluation model using the Structural Equation Model (SEM) from experiment of usability on using vehicle. Vehicle developers have been adding many functions for enhance the user satisfaction. But it will be made the trade-off problem of usability and design elements of vehicle interior from attempt to make best usability satisfaction in a restricted space. To solve the trade-off problem, we set a new solution criterion from usability evaluation model. The usability experiment is based on major activity pool from derived user's acts pattern in vehicle for make more accurate usability evaluation model. And this model was built with twenty-nine measurement variables for the evaluation of usability of vehicle user. As a result, the proposed SEM model showed statistical significance as well as a high level of R Square (0.7144). This model shows the relationships of detailed usability and design elements. According to the result, this study introduces the criterion to secure the best satisfaction of usability and design elements.

The aim of this study is to propose the effective management plan for (New) Library at International Science Business Belt in Korea. For this purpose, this study analyzed cases of domestic and overseas libraries which have been providing the special Science Business Service. Also user questionnaire surveys were conducted for the user demand in (New) Library. Based on case studies and user surveys, the management plan for ISBL was suggested as follow with its division into five realms; that is, information resources and special programs, manpower, space facilities, internal cooperation and international network. The research could be used as basic resources for the International Science Business Library in Korea.

System solutions for access control to the user's personal when you want to authenticate to the system is used. The valid user is really just a part of authorized users, the suitability of a valid user has been authenticated are not sure whether the problem is the fact. For example, one developer in the Unix operating system can be valid, but do not have permission to access the system should be limited for. In this paper, a single account for multiple users to use the system operational issues to improve the fine-grained delegation of authority, the session audit, the administrator account's policy-based management, with full rights the administrator account of distribution management and auditing the system overall is the study of access control measures.

Purpose: This study attempted to verify which factor affects the intention to use of the connected car that has recently emerged. Methods: Based on prior researches, this study derives the characteristics of connected car that affects user intention and designs research model for empirical analysis. A structured questionnaire was conducted for those who drive cars, and a total of 292 usable responses were collected and empirically analyzed using SPSS and PLS. Results: The results of this study are as follows; service quality, hedonic motivation, and social influence have a significant effect on perceived value, but system quality, information quality, user innovation, experience and facilitating condition did not. In addition, it was found that system quality, information quality, service quality, user innovation, facilitating conditions and social influence have a significant effect on satisfaction, but hedonic motivation and experience did not affect satisfaction. Conclusion: The findings of this empirical analysis have implications for effectively recognizing the value of connected cars based on the technology of information systems to users and establishing sustainable growth strategies for connected car producers and suppliers.
