In IT service quality research, the relationship between the service quality and clients' satisfaction was the focus of many studies while in relationship quality research, the influence of trust and conflict on relationship commitment seems to be the focus. In this study, these two research streams are integrated and a theoretical research model is proposed consisting of IT service quality, satisfaction, trust and relationship commitment with conflict as a moderator for the overall psychological mechanism. As satisfaction represents emotional response while trust cognitive response, this research model integrated both emotional and cognitive aspects of relationship maintenance in the IT service context. Analysis of data collected from 262 employees of global IT service firm revealed the differential effects of reliability, responsiveness, assurance and empathy on satisfaction and trust. Also, depending upon the level of conflict, the effects of reliability and assurance were found to be moderated. Further analysis revealed more profound mechanism at work relating emotional and cognitive aspects in the psychology of relationship maintenance in IT service context. Practical implications are further discussed in the conclusion.

With the development of information and communication technology, logistics distribution systems and services have been improved, new types of services have been provided, and consumption patterns in consumer markets have also changed. In the domestic distribution market, the development of ICT technology, the spread of smart devices, and the growth of the e-commerce market have led to Omni-channel, a service that integrates offline channels and online channels. Omni-channel service aims to provide consumers with consistent and convenient service by integrating offline and online domain into one. Consumers can get integrated service on and offline. In this study, consumers' intention to use Omni-channel was examined by Self Determination Theory and SERVQUAL. The survey was conducted on Omni-channel user and the research model was composed of 2^nd order factor model considering the characteristics of Omni-channel which provides integrated service based on the prior literature and PLS-SEM (partial least squares structural equation modeling).

We are concerned with whether a vertically integrated broadband and content provider can unreasonably advantage itself over competing content providers, either by selling quality-of-service (QoS) to content providers at unreasonably high prices, or by refusing to provide access to QoS to competing content. We address this question by modeling the competition between one such vertically integrated provider and one over-the-top (OTT) content provider. The broadband provider decides whether to deploy QoS, and if so it also determines the QoS price if sold to either the OTT content provider or directly to users. We analytically determine when the broadband provider will sell QoS and when the OTT content provider or users will purchase QoS. We characterize the optimal QoS and video service prices. The Internet service provider (ISP)'s market share increases with the difference in the value of the two video services and decreases with the difference in the corresponding costs. Numerical results illustrate the effect of QoS price on content price, the variation of prices and profit with QoS price, and the variation of prices and market shares with the benefit of QoS. The ISP may sell QoS to users at a lower price than when QoS is sold to the OTT provider.

UPnP AV Framework automatically integrates and manages various AV devices that are connected to network as an important component in home network. Therefore, user can access and control AV contents at any time. But, other existing home entertainment systems target multimedia service support that is based on multimedia home server system. In this paper, we propose an integrated home entertainment system (u-MUSE system) that supports remote control service. It can manage application in remote AV device or control AV contents directly in home network environment. The proposed system sufficiently performs role of control center for electronic devices in home via integrated system control and AV contents playback service.

The information systems of the Korea Postal Service are developed not for integration based on strategic purposes but for improvement of low-level business processes within each functional unit. Hence. the as-is level of the information systems is very insufficient for information integrity, and also shows substantial gaps. when compared to recent advances in information envconment such as internet, electronic govemment and so on in this study we suggest the design of the integrated platform to achieve integrity of postal service and banking servive. After briefly addressing the issues on information systems of the Korea Postal Service. we provide the framework of the integrated platform and action plan. We believe when this framework is put into use. It can contribute to competitive performance by giving the integrity and consistency in implementing infomation systems of the Korea Postal Service.

Purpose: This study aimed to prepare basic data for the development of a nursing intervention program to improve nursing performance by identifying the factors affecting nursing performance in an integrated nursing care service ward. Methods: Participants were 166 nurses who had worked for more than six months in the integrated nursing care service wards of three general hospitals located in B city. Data were collected from July 15 to August 30, 2022 using structured questionnaires and analyzed by T-test, ANOVA, Scheffé test, Pearson's correlation coefficients and multiple linear regression using the IBM SPSS/WIN 25.0 statistical program. Results: Factors affecting the nursing performance of participants were age (β=.58, p<.001), positive psychological capital (β=.41, p<.001), and social support (β=.28, p<.001). The total explanatory power of these variables for nursing performance was 55.8%. Conclusion: The results of this study suggest the need for programs that improve psychological capital and social support while considering nurse's age to enhance their performance in nursing integrated service wards.

Purpose: The purpose of this study is to derive basic data for desirable location and functions of the integrated care center. Methods: Survey, Questionaire and statistical analysis are the main research method of this study. In order to collect data related to utilization pattern and favorite functions of the senior people, researchers have visited 4 social welfare facilities located in Southern Gyeonggi Province. 403 questionaires have been gathered from 4 facilities and they have been analyzed by using Excel Program of MS. Results: First, compared to other services, healthcare services have been preferred by many older people in Social welfare Facilities. This means that integrated care centers providing healthcare services for older people rather than services for children or disabilities is desirable. Second, Integrated Care Centers had better be established within the walk distance of elderly people. If it is not easy, the introduction of shuttle bus for older people is desirable. Especially, in case of large Care Center. Implications: This study shows that small facility with community care rather than big facility is desirable for small community in the point of friendliness, convenience, economy, etc.. However it is necessary to combine welfare service and healthcare service even in small centers.

In CALS/EC environment, there are geographically dispersed heterogeneous databases and various applications. Integrated database environment provides transparent access mechanism for heterogeneous and distributed databases and interoperability between applications in various platforms. Because elements exist geographically in integrated database environment, directory service is necessary for providing unique access mechanism for elements. In this paper, we design a directory service using CORBA based access interface and object-oriented DIB model for accessing transparently to elements and interoperability with other information system.
