In current web-based systems, it is generally recognized that one way flow of information from providers to users can cause the static problem of document structure. Therefore, information update frequency and interaction between providers and users are quiet slow. Monopolized information can obstruct the free user's access and heterogeneous format and different protocols also make users difficult to retrieve and to collect information. To resolve these problems, in this study, we introduce the Web 2.0 to move toward the user's participation and share based on the social network and the OAI protocol to improve the free access and the interoperability on bibliographic information for Life Science and then design the bibliographic information network for life science. This network has four main functions such as: 1) Open Repository function that can make up user community for sharing and data exchange. Data such as article, seminar material, research note and research report are considered in design. 2) Open Collection function that can collect and store the metadata on distributed bibliographic information networks, 3) Open Access function that can manage the metadata in the open access environment, and 4) Administration function that can monitor the user activity and statistics and can inspect the registered data.

The purpose of this paper is to analyze the structure and characteristics of the utilization support systems(USS), which has been institutionalized to aid the use of social welfare services in Japan's social welfare systems recently. In order to conduct such purposes, this paper made the process as follows. Firstly, this paper examined the developmental processes of social welfare systems, and the back ground of institutionalization of USS in Japan. Secondly, this paper formulated at ideal dimension the analytic model which was to explain the structure and characteristics of the USS. To build this model, this paper used two factors which were the connective dependency to the welfare support systems and the feasible-satisfying alternative setting for user. Thirdly, this paper analyzed the characteristics of the user-driven support facilities which has already activated in social welfare systems in Japan. According to the result of analyzing such model, this paper explained that USS in Japan has possessed the structure and characteristics, such as to aid self actualization and human right of user, to compose the inner coalition organization with supply systems, to emphasize the employee to train care management's skill, and to keep up bounded openness to USS's participation. Therefore, oligopoly market is formulated owing to bounded openness in the field of USS and the role of social worker such as a care manager is emphasized on making care plan.

In immersive virtual environments including mixed reality (MR) and virtual reality (VR), avatars or agents, which are virtual humans, are being studied and applied in various ways as factors that increase users' social presence. Recently, studies are being conducted to apply generative AI as an agent to improve user learning effects or suggest a collaborative environment in an immersive virtual environment. This study proposes a novel method for interface application of a virtual assistant agent (VAA) using OpenAI's ChatGPT in an immersive virtual environment including VR and MR. The proposed method consists of an information agent that responds to user queries and a control agent that controls virtual objects and environments according to user needs. We set up a development environment that integrates the Unity 3D engine, OpenAI, and packages and development tools for user participation in MR and VR. Additionally, we set up a workflow that leads from voice input to the creation of a question query to an answer query, or a control request query to a control script. Based on this, MR and VR experience environments were produced, and experiments to confirm the performance of VAA were divided into response time of information agent and accuracy of control agent. It was confirmed that the interface application of the proposed VAA can increase efficiency in simple and repetitive tasks along with user-friendly features. We present a novel direction for the interface application of an immersive virtual environment through the proposed VAA and clarify the discovered problems and limitations so far.

For urban parks' rational and efficient management, research on creating green spaces in living area through citizen participation is continuously being conducted. However, in existing studies, citizens are recognized as a homogeneous group, and research on the intention to participate in park management according to user characteristics has not been conducted. A few studies have attempted to show differences through conceptual variables, such as user satisfaction and attachment to parks, but studies on sociodemographic factors, such as the users' age, have not been conducted. This study was conducted to ascertain the differences in preferred parks and park management participation methods by age, targeting various parks located in ten districts of Incheon Metropolitan City. Regression analysis was performed after collecting 1,226 questionnaires, applying a population-proportional allocation in the ten districts. As a result of the study, it was found that the difference according to the age of users has the most influence on the willingness to manage the park rather than the satisfaction or other factors. Also, a chi-square analysis was conducted to find the differences in preferred urban parks and management methods by age. The results showed that the choice to manage parks was statistically higher for those in their 50s or older, and the differences in preferred park types and desired park greening methods suggested implications for park management plans by age.

The balanced scorecard(BSC) framework is a tool for strategic decision making and task support that aims for efficiency in performance management and strategy execution. BSC evolved from an old performance management practice, which tended to be limited to a finance-only perspective, to a new system of corporate management looking at corporate tasks from a multi-dimensional, future-inclined value perspective. This form of BSC amounts to a framework capable of driving management innovation and renewing the ways in which companies conceive their strategy and perform their operations. Since BSC draws integrally on user participation, it can be expected that users' satisfaction with BSC systems is an important factor in systems' success or failure. However, previous studies of the BSC system have not yet considered it as a theoretical model, specifically examining BSC system and task characteristics. To date, only a few studies have put forward plans for the implementation and use of BSC systems, and these studies have the common limitation of failing to consider the circumstances or theoretical structure of the companies for which a BSC system is being proposed. This paper then begins to fill some of this gap by characterizing the BSC system from the perspective of contingency theories. Contingency theories can be particularly useful in the Korean context in exploring how different companies use the BSC system in ways determined by their unique environmental characteristics, which may also determine the performance factors behind the application of a company's particular BSC system. In order to provide concrete suggestions for implanting and using the BSC system from a contingency theory perspective, this study sets out to determine the relationships between the contingency variables affecting BSC system performance and BSC system property variables(in given cases) through an empirical analysis. The study takes into account the perspective from which contingency theory is to be applied in individual cases, sets contingency and BSC property variables with reference to the BSC system user's environment and BSC system's character, and frames initial hypotheses concerning corporate structure and environmental variables and BSC system performance variables with reference to previous studies. A survey was then conducted on users in Korean companies that have implemented the BSC system in order to verify the research model and understand results.

Purpose The first purpose of this study is to investigate factors that are likely to influence user's intention to adopt third-party mobile payment platform. A comprehensive study about mobile payment services have used various variables to explain user's use intention based on the theory of reasoned action (TRA) or the theory of planned behavior (TPB). Variables such as simplicity, security, costs, relative advantage, individual mobility, subjective norm, trust, satisfaction, attitude towards use, perceived usefulness, perceived ease of use and so on. Among these factors, we expect to find out the most influential factors effecting user's use intention of the third-party mobile payment services. Second, we also examine whether the most influential factors have the same influence to different third-party mobile payment services by conducting comparative study of Alipay and WeChat Pay. Design/methodology/approach Empirical data for this study were collected from Chinese who has the experience using or have used Alipay or WeChat Pay. Participants needed to be familiar with Alipay or WeChat Pay because such users may be more aware of both the advantages and disadvantages of Alipay and WeChat Pay. We conduct a pilot test using Smart PLS 2.0, which includes 50 Alipay users and 82 WeChat Pay users. The result indicates that all the measurement fit for the context. And then 980 questionnaires were mainly sent out to the college students and the e-mails users randomly. To encourage participation, we give the participants a small gift as a present. Finally, we received a total of 683 replied. Data from respondents who gave incomplete or invalid answers were excluded to assure the validity of the constructs. 79 questionnaires were rejected, finally the valid data are 604 (with 372 Alipay users and 232 WeChat Pay users). Findings The results suggest that users' intention is determined by their trust on third-party mobile payment service and perceived usefulness of use. Comparative study results also indicated that the factors have different influence on Alipay group and WeChat Pay group, which offers a new aspect for academic field, and provides useful information to mobile payment service providers in China.

The survey research was executed from 27th July to 15th September, 2002. Then the collected data were analyzed by using the SPSS 10.0 for windows program. The research results are as follows. Firstly, in the satisfaction degree of the user's family about the daily service showed the highest satisfaction degree for the kind service of the staff to the users. In the satisfaction degree about the specialized service of the user's family, the satisfaction degree was high in bedsore prevention, periodical health care, proper medical treatment, family counsel, and adequate disease management. In the satisfaction degree about the facility and environmental service, the satisfaction degree about the surrounding environment of the facility or safety facility, and the comfort condition was high. In the satisfaction degree about the services related to the local society, it was high in the hospital and medical-related field. Secondly, in the demanded services, the demanding degree for worship, mental and spiritual nursing, hospice, funeral service, family meeting, and support for the special vehicle were not so high, but it was shown that they were generally demanded. Thirdly, it was shown that the provided services had an overall high satisfaction degree. In the service satisfaction degree according to the general characteristics of the user's family, it was recognized that there was a significant difference between the distinction of sex and local society related services. Also, there was a significant difference in the satisfaction degree between age and specialized service. Through the above research results, detailed rehabilitation programs such as linguistic treatment and working treatment should be more and more compensated in order to supplement the insufficient points of the services provided by the charged recuperation facility specialized in the old. Additionally, the correlation with the local society such as education and training for specialized human labor, close cooperation among the facilities, and positive participation in local society events are thought to be reinforced.
