Trust affects marketing practices and purchasing performance in the context of buying and selling business services. Despite the importance the previous studies on business services have not fully investigated the role of trust and the effects of trust on buying and selling strategies. Additionally in-depth studies exploring the links between trust-strategies-performance have not systematically performed both in domestic and international markets. This study, in the context of purchasing business services, investigates the effect on trust of suppliers' characteristics and relational characteristics between sellers and buyers. This study also explores the effect of trust toward sellers and buyers on purchasing performance. The results of this study should contribute the understanding on the role of trust in purchasing and selling business services. Building and maintaining trust must be one of the major key success factors in the relationship between sellers and buyers of business servies.

This study aimed to clarify the multifunctional services and space composition in the process of developing a multifunctional long-term care program in small elderly care facilities in Japan. We collected data about multifunctional long-term care at small facilities from the Community Life Support Center (CLC), a Japanese non-profit corporation, and conducted an interview survey of the members of the CLC's secretariat in 2014. Furthermore, we selected 3 Japanese pioneering care facilities (known as takurosho), and conducted interview surveys and data collection to clarify in detail the space composition and process of development of multifunctional long-term care at small facilities. Four distinct results were found. First, the facilities had gradually increased non-institutional services, including visitation, overnight stays, and long-term stays, to fit the needs of users and their families. Secondly, in the 1990s, they could offer both non-institutional and institutional services at the same facility, but after the long-term care insurance system began in 2000, non-institutional long-term stay services were not allowed. Third, the facilities had built extensions or extra rooms in response to increases in multifunctional services and users. These rooms had common characteristics, with sitting rooms at the center of the facility. Lastly, the maximum number of service users at each of the 3 facilities was limited to 15, to maintain a small scale. However, as the size of facilities was increased through building extensions or remodeling, the overall amount of area available to users increased.

The majority of next generation information systems will be working on portable mobile devices such as smartphones. REST Open API web services have quickly become popular among mobile application development. The use of REST web services are not only growing in popularity but totally changing the way of mobile applications development. This is because REST web services could be used in application development as a form of building blocks, which is completely independent, compatible, to any platforms. With this strength, REST web services encourage third party application to build add-on functionality. This research proposes the use of REST web service to replace the use of socket APIs into major internet communication APIs. To this end, this paper also provide performance evaluation of the REST web services compared to the conventional socket APIs, focusing on scalability by analytical and experimental evaluations. Finally, we summarize the possibility whether REST Open API web services have enough performance as future major internet communication primitive APIs.

While cloud services are expanding, many users are having difficulty in adopting cloud services. This is because there is no information as to which cloud services can be trusted by users. loud service level agreement (Cloud SLA) is an agreement between cloud service providers and cloud service consumers using qualitative and quantitative indicators including quality and performance, etc. of cloud services. In this study, we propose a framework for cloud SLA that can be applied to the domestic cloud industry to improve service levels for cloud service providers and to protect users and also derive the detailed components of cloud SLA applicable to the domestic cloud industry using the proposed framework. Through this result, it is expected that the government will utilize the policy to enhance the reliability between cloud service providers and users under "the Act on the Development of Cloud Computing and Protection of Users", and eventually to activate cloud services by improving the quality and performance level of domestic cloud services and building a user trust.

As customers are becoming increasingly important in corporate management, there is a growing demand for migration to customer-focused organizational structures. Unlike the manufacturing industry, the construction industry is non-iterative and non-standardized. As a result, a wide variety of materials, human resources, technologies and equipment must be mobilized in complex work activities to complete a structure. Consequently, surprises are bound to occur as such work activities progress. This paper intends to study a strategy that is designed to improve customer services for apartment building units. It aims primarily to focus on cost control and brand management. Housing tenants and industry experts are surveyed to collect input for issue analysis. In addition, the external circumstances and internal capabilities of major builders in Korea are analyzed, and a SWOT analysis is performed regarding market conditions related to customer service. These analysis results are utilized to develop a strategy implementation plan over different time frames, and the operational resources available for such strategy implementation are analyzed in order to forecast its performance. This research will facilitate communication between construction companies in Korea and their customers by proposing a customer service improvement strategy for apartment building units, and is expected to provide resource material for a strategic analysis of efforts to fully incorporate customer requirements

Georeferenced SLI(Street-Level Imagery) services such as Google Streetview, which contain abundant information about the real world, can increase its applicability substantially through conflation with other spatial datasets. For this purpose, we propose a method to improve a correspondence of building region to combine building information more accurately. First, the spatial inconsistency between SLI and vector map is removed by alignment based on road intersections. Then, visible building regions are searched from the spatial inconsistency-removed vector map, and the optimal corresponding building areas are determined in the SLI scene using the visible regions as seed information. The experimental results demonstrated that our method had improved the accuracy of building region correspondence by about 8%. Therefore, our method can be utilized effectively for enhancement of conflation service based on the SLI.

Construction accidents are major problem in Turkish Construction industry and especially fatally rates are very high. Current legislative system on occupational safety in Turkey enforces employers to implement safety measures as well as safety management systems. However level of consciousness in the industry is unsatisfactory and safety are perceived as extra cost and unnecessary expenditure. Moreover, especially in small residential building constructions which have a big share in the industry and unfortunately safety measures to mitigate or abate construction risks do not exist. The study focuses on small residential building construction sites and in the scope of this study, thirty building projects are examined. For each building project, project cost including labour and material costs, service and consultancy costs for mechanical, electrical systems as well as architectural and structural services, costs for supervision and finally general expenditures for construction site facilities were calculated. On the other hand, occupational safety costs for personal protective equipment, collective protective measures, consultancy and training were determined. Work breakdown structures were established and for each work item firstly occupational risks were evaluated and furthermore according to risk scores safety measures to be implemented were defined and related costs were calculated. The study gave results for total safety cost on average, in terms of percentage of total project cost (3.73% of total project cost), safety cost per man-hour (0.40 USD) and safety cost in terms of unit construction area (11.60 USD per square meter). Since safety management is a part of whole project management process, study gives suggestions and techniques to calculate safety costs and implement safety measures as a part of project management service for professionals. Authors believe that suggested approach may easily developed by the usage of more data to establish a model for estimation not only for building construction sites but also for all construction projects.

Recently, various mobile services are provided by the spread of wireless network infrastructures and smart devices. The improvement of cloud computing technologies increases the interests for enterprise mobile cloud services in various IT companies as well. By increasing the interests for enterprise mobile cloud services, it is necessary to evaluate the use of enterprise mobile cloud services. Therefore, the factors which affect the user acceptance of enterprise mobile cloud services are analyzed on the basis of Davis' technology acceptance model in this research. As analysis results, four external variables have significant effects on perceived ease of use of mobile cloud services. Also, these variables indirectly affect attitude toward using cloud services. The results show that the security is the most important factor for attitude toward using enterprise mobile cloud services. The service users also consider the interoperability as an important factor for the user acceptance of cloud services. The perceived ease of use has more contribution than the perceive usefulness on attitude toward using enterprise mobile cloud services. This research has both industrial and academic contributions because it provides the guideline to companies for introducing the enterprise mobile cloud services and apply the technology acceptance model on new IT services.

The final goal of this study was to develop an optimal service scenario to ensure that building occupants can be effectively evacuated from the building within the golden time without extra assistance in preparing and evacuating for fires. In addition, the research was carried out by dividing the current services into fire evacuation and preparedness phases by applying the Double Diamond process in order to find a way to better familiar them as a lifestyle and to always be prepared for fires. For the building occupants and managers, a total of 14 ideas were first suggested, including not only the services of how to evacuate from a fire, but also the life-style service functions associated with fire implementation technology in daily life. The 14 proposed ideas were conducted by the Service quality evaluation and Analytical Hierarchy Process(AHP) from the perspective of the service recipient, and those were finally prioritized from the service provider's perspective, taking into account the cost and practicality of the service provider. The results of this study show that differences in the importance of fire phases considered by stakeholders and the perception of fire generally vary considerably.

Information technology will inevitably and profoundly alter every aspect of university life. New information technologies are creating new patterns in the research and teaching, with networks enhancing information sharing and data transmission. The revolution in information technology requires that universities integrate information technology with their traditional missions of teaching, research, and public service. Enhanced mode of information access and changing information-seeking behaviors suggest the need for new library services. New technologies have opened up many new services options for libraries. The nature of and potential for new information services suggest that libraries should become better connected with other campus units. Some of these issues will no doubt be addressed by the a n.0, pplication of new technologies and by building campus information infrastructure. An important element of the needed change for enhancing the library information services is the integration of the libraries and computing centers. Libraries and computing centers deal with the same commodity-information and delivering information. For the sake of scholarship and research, the two must devise an integrated a n.0, pproach to delivering the common commodity. Computing centers have special skills in system development and telecommunications. Libraries have good human interface skills and skills for organizing knowledge. Together they could be a particularly productive team. Noting this, some universities have created new information service units which unify the present-day computing, library and telecommunication functions. Existing models range from true merging to situations where some cooperative activities are being conducted. The purpose of this study is to suggest the direction in developing of information services in academic libraries by examining the changing information environment and trends of integrating libraries and computing centers. This paper inquires into the changing information environment, the impact of imformation technology on universities and libraries, some casses of integration of academic libraries and computing centers, and effects of integration of two and suggests the developing direction of information services in academic libraries.
