Maintenance services provided to users in buildings are not sufficient simply to provide them, but it is necessary to provide them with a service system that can accurately identify and respond to users' needs. This study analyzed the relationship between user satisfaction with the helpdesk service corresponding to the building claim and the quality of service of the maintenance organization to identify the interaction between the user and the maintenance organization in the building. We then examined whether there were significant differences between the buildings in terms of variables in the helpdesk service that affect the user's satisfaction. It was also presented as a measure of the quality of service of the SERVQUAL tool to assess the potential for building maintenance response strategies. Research shows that each building has a helpdesk service item that is significant in user satisfaction and empathy has emerged in a typical dimension as SERVQUAL dimension.

The technological advances within the Internet industry have led to a revolution in terms of how people communicate with each other. For example, users are no longer limited to using face to face interactions to connect and communicate with their peers but can use email, instant messaging and more. A recent trend that researchers are observing is the adaption of SNS. SNS such as facebook and myspace has been a dominant global trend and has grown dramatically in the past 5 years. The purpose of this study was to test SNS usage motivations influencing the user satisfaction. The research model was developed based on literature review. SNS usage motivations consist of five factors: expression, relationship formation, social exchange, information seeking, trend. 189 questionnaires were used for the main part of regression analysis. The analysis results revealed that relationship formation, social exchange and information seeking were very significant factors influencing the user satisfaction. Especially, social exchange was the most significant factor. We can prospect that importance of user satisfaction on SNS usage motivations is more and more increasing in the future.

Mobile wallets have been in continuous demand and developed over the past few years, especially during the COVID-19 pandemic. Several studies have examined user intentions and perspectives. This study develops a conceptual model combining behavioral factors with the technology acceptance model (TAM). The goal is to identify key factors that influence user's intention to adopt mobile payments. This study uses the TAM and the unified theory of acceptance and use of technology (UTAUT) models with additional factors. The additional factors are security, trust, facilitating conditions, and lifestyle compatibility. The study analyzes the results of a survey of 394 Saudi citizens conducted via an online survey. The results indicate that user attitudes and intentions are positively influenced by all of the factors. Perceived usefulness, perceived ease of use, lifestyle compatibility, and facilitating conditions are direct predictors of user behavior in accepting mobile wallet payments. This study provides an empirical contribution to the literature on mobile payment acceptance on the effect of perceived usefulness and lifestyle compatibility. The results demonstrate that about 26% of the respondents started using mobile wallet services because of the COVID-19 pandemic.

This study analyzed the intention of continuous use of the electronic attendance-absence system. Perceived ease of use, acceptance attitude, and user satisfaction variables were selected to analyze the factors affecting the intention of continuous use. To achieve the purpose of this study, a survey was conducted targeting students who had experience in using the electronic attendance-absence system at K University located in Chungcheongbuk-do. The use environment of the electronic attendance-absence system was non-face-to-face, and the questionnaires answered by 921 students were analyzed. The study results are as follows. First, perceived ease of use and acceptance of the electronic attendance-absence system were found to have a positive effect on user satisfaction. Second, it was found that the learner's perceptual ease, acceptance attitude, and user satisfaction for the electronic attendance-absence system had a positive effect on the intention of continuous use. This study is meaningful in that it identified the intention of continuous use based on the experience of the electronic attendance-absence system in a non-face-to-face environment.

In order to meet the different requirements of a wide variety of user applications, the network should support the different quality of service requirements for different applications. While 3GPP has specified a number of QoS profiles for a 3G-GPRS (or UMTS), the implementation of QoS management is an issue. This paper presents the QoS management functions in the 3G-GPRS. The QoS management involves service manager, translation function, admission/capability control, and subscription control of users, and mapping function, classification function, resource manager, and traffic conditioner of user traffic. It also describes the QoS Management procedure during the session management when setting up the bearers.

The purpose of this study was to suggest the more efficient system for management in urban park through the investigation of the managemental condition. Research sites for managemental condition were 9 municipal park managemental offices in Seoul, Pusan and Taegu. The degree of the managemental state in these parks was generally passive and low. So, each of them had to consider the ways how to buy private-owned sites, to standardize facility maintenance, to characterize the managemental objects, to enlarge managemental personnels and systems, to apply entrusting management, to plan user-service strategies and to shorten expenditures. Particularly the positive managemental improvement in user control was demanded to cope with the changing social needs. In long term, they had to develop basic elements for the reasonable park management, clear park maps, area of facilities, the event, citizen participation, budgets and etc., and had to prepare the middle-long term management plan and the precise analysis to the managemental criteria.

Aiming at the problem of service reliability in resource reservation in cloud computing environments, a model of dynamic cloud resource reservation based on trust is proposed. A domain-specific cloud management architecture is designed in which resources are divided into different management domains according to the types of service for easier management. A dynamic resource reservation mechanism (DRRM) is used to test users' reservation requests and reserve resources for users. According to user preference, several resources are chosen to be candidate resources by fuzzy cluster analysis. The fuzzy evaluation method and a two-way trust evaluation mechanism are adopted to improve the availability and credibility of the model. An analysis and simulation experiments show that this model can increase the flexibility of resource reservation and improve user satisfaction.
