The Lambda Networking is emerging to provide the high bandwidth stably for advanced applications such as a large file transfer in High Energy Physics and an Uncompressed HDTV streaming. The User Controlled LightPath(UCLP) is a software to facilitate the Lambda Networking. The UCLP is scalable as using Web Services to define and manage network resources. In this paper, we describe how we deployed the UCLP into KREONet2 and GLORIAD-KR. We also present that the original UCLP creates only a link-level APN due to a SONET technology. As employing a Virtual LAN (VLAN) of the layer2 technology in the UCLP, we can efficiently create a network-level APN.

Although the proportion of frail elderly among the elderly population has been rapidly increasing, there is little preparation to provide housing alternatives for them in Korean society. Long-term care facility a housing alternative for frail elderly that enables them to receive social and medical care services that enhance the quality of their life. This research was conducted to study the opinions of middle-aged Koreans about long-term care facilities for the frail elderly. This study provides useful suggestions for the development of user-paid long-term care facilities in the near future. A survey questionnaire was administered to 600 adults in their 50s to collect data. The sample was stratified according to region, gender, and housing structure type. The results showed that most of the respondents were aware of long-term care facilities for the frail elderly; but they were relatively unwilling to live in these facilities, as compared to other housing alternatives. However, a larger number of respondents said that as they became very frail, they would be willing to live in these facilities. The respondents expressed a high level of need for user-paid long-term care facilities as an alternative to hospitalization. Also, they wanted to have a variety of long-term care facilities that are designed for different levels of disability. The education level of respondents and their spouses, average monthly income, subjective economic level, and religion were major variables that differentiated significantly the opinions about long-term care facilities for the frail elderly.

This study analyzed library awareness and anxiety among people in their 20s living in East Asia. The objective is to develop the international library cooperation agenda for life-long education proliferation. User groups in Korea, China, and Japan were investigated to understand the differences in library awareness based on the situational contexts such as preferred resources, use frequency, educational level, and gender. Results of the data analysis showed the correlation between library anxiety and use patterns such as preferred information sources and frequency of use. Specifically, the user group in China has the highest level of library anxiety with every factor. Also, the Korean user group was measured to have the lowest level of library anxiety in terms of digital information factor. Based on these results, the study presents several recommendations for resolving library anxiety such as embracing new information need with regard to environmental change and suggesting a new space policy for libraries.

In this paper, we introduce a novel Climate & Environment Database System (CEDS). The CEDS is developed by the National Institute of Meteorological Sciences (NIMS) to provide easy and efficient user interfaces and storage management of climate model data, so improves work efficiency. In uploading the data/files, the CEDS provides an option to automatically operate the international standard data conversion (CMORization) and the quality assurance (QA) processes for submission of CMIP6 variable data. This option increases the system performance, removes the user mistakes, and increases the level of reliability as it eliminates user operation for the CMORization and QA processes. The uploaded raw files are saved in a NAS storage and the Cassandra database stores the metadata that will be used for efficient data access and storage management. The Metadata is automatically generated when uploading a file, or by the user inputs. With the Metadata, the CEDS supports effective storage management by categorizing data/files. This effective storage management allows easy and fast data access with a higher level of data reliability when requesting with the simple search words by a novice. Moreover, the CEDS supports parallel and distributed computing for increasing overall system performance and balancing the load. This supports the high level of availability as multiple users can use it at the same time with fast system-response. Additionally, it deduplicates redundant data and reduces storage space.

Mobility as a Service(MaaS) is an integrated mobility service that enables flexible reservation and payments for various transportation services on one platform, including existing public transportation. To popularize MaaS, users need to be satisfied with the service, and the factors that lower satisfaction need to be improved. In this study, the structural equation model was used to identify the influence of factors on the overall satisfaction level. Improvement plans to increase user satisfaction were derived based on importance-satisfaction analysis and the decision tree model. The analysis revealed the level of connectivity in MaaS apps to be a significant factor that needs to be improved for a higher user satisfaction level of MaaS

This paper investigates the relationship of service quality and user satisfaction in the wired and mobile Internet services based on the integrative framework of both systems. Given a moderate level of reliability and validity, the commonly driven dimensions for measuring service quality include responsiveness, assurance, empathy, convenience, usefulness, and diversity. User satisfaction is measurable by the dimensions of communication/entertainment, finance/economics, location/geography, and information/consulting. We apply the MANOVA tests to evaluate whether each of the service quality dimensions has an overall influence on user satisfaction. Next, multiple regression analyses are conducted to check if unique positive effect exists between each combination of service quality dimensions and user satisfaction dimensions. The results show that service quality must be taken care of with respect to the assurance dimension in order to enhance customer satisfaction in the dimensions of location/geography, which will contribute to increasing the utilization of mobile service. For improving user satisfaction in the dimension of information/consulting, service quality must be supported with respect to assurance and empathy in the mobile Internet market, in addition to diversity, which is the only significant service quality in the wired Internet service.

By exploring plausible relations between factors of service quality and user satisfaction, this study has derived significant determinants of user satisfaction. Based on the analytical findings, this study suggested practical measures to enhance user satisfaction of special libraries. If we determine the priority order of three dimensions of service quality depending on specialized areas of special libraries, and revise the items of higher correlations with user satisfaction, then we could effectively and efficiently level up user satisfaction of special libraries.

This study analyzes MMORPG in user's desire perspective and tried to find specific motivation factors. In research result, character has been separated in user character, another user character, boss monster and support character. And character's factor analysis yielded three factors: visual attraction, psychological propensity and competence. The result of the regression analysis about character's motivation factor show that it is significantly different that motivation level and motivation factors from each character. This finding implies that specific motivation factors can serve to make strategy for motivate user's game playing.

This paper researched social, cultural background, psychological bases, design method and design types with regard to user's participation in space design. This issue of user's participation became one of major paradigms of 21st century not only for space design but also for every other cultural phenomenon. First chapter is an introduction. Second chapter tried to assert the fact that user's participation will be the important aspect for future space design by proving the correlation between user's participation in space design and the important social changes. It also tried to prove the psychological reasons why the users' participations affect the level of user satisfaction. It can be explained by Behaviorism which insisted that our outer behaviors affect our inner attitudes and preferences. Third chapter explained the affordances in design which works as a means of inducing user's participatory behaviors. Fourth chapter proposed the types of participatory space designs classified by the users' behavioral features and their characteristics, intending that they will verify the realization of the theories which we discussed in the former chapters regarding the users' participation in space design. The fifth chapter is a conclusion which says that outwardly, those participations are simply making external changes in design. but actually, they are reflecting more profound social changes and making important psychological effects on users.

As the size of camera modules is decreasing and as the computing performance of portable devices is improving, taking photos has become a part of daily life. However, existing photo management programs and products that manage such photos still require extensive user effort to facilitate the sharing and browsing of images. It is especially difficult for novice users to manage and share photos. In this paper, we develop a round-robin concept-driven user preference feedback mechanism for achieving direct photo sharing, instant display, and easy management using optimized user controls and user preference-driven classification. Compared with commercial photo management systems, our proposed solution provides new features: optimized user controls, direct sharing and instant display, and user preference feedback driven classification. These new features boost the round-robin concept-driven user preference feedback. This paper proposes a photo finder that automatically searches for photos in storage spaces or cameras. The proposed photo finder relies on user preference feedback to share photos by leveraging user preferences, and the round-robin connection transmits photos to the family's digital photo frame or web album by arbiter. The proposed method saves time and spares users the effort required for photo management. Moreover, this method does not merely direct photo sharing and simple photo management, but it also increases the satisfaction level of users viewing the photos.
