Despite the growing interest in technostress phenomenon of employees in organizations, few guidelines exist about how mangers can effectively control their technostress. Accordingly, scholars should pay greater attention to how firms can successfully manage employees' technostress. This study conceptually developed and tested a research model for understanding the influence of technostress on psychological and behavioral strains. In addition, we tested technical support provision as a moderator. We obtained 107 samples through a survey questionnaire, and data were analyzed based on structural equation modeling (SEM). As a result, it was empirically demonstrated technostress decreases job satisfaction and individual productivity. We also found that technical support provision have moderating effects on the relationship of technostress and job satisfaction/individual productivity.

Towards the deployment of 3rd generation systems, Virtual Home Environment (VHE), stemming from 3GPP, appears to be a powerful concept advocating the provision and delivery of personalized services to roaming users across network and terminal boundaries. This paper aims to expose the pathway for materializing the VHE concept, via the specification, implementation and evaluation of a prototype. Core aspects for realizing the concept such as the business and roaming models are presented, while a VHE enabling architecture utilizing key technologies (OSA/Parlay, MExE, and USAT) is introduced. The proposed architecture has already been evaluated by performing an initial trial demonstration. Currently it is being extended to support VHE service provision to roaming users, an aspect to be addressed by the final trial.

Bolted connections are suitable due to high quality prefabrication in the factory and erection in the workplace. Prefabrication and modularization cause high speed of erection and fabrication, high quality and quick return of investment. Their technical hitches transportation can be removed by prefabrication of joints and small fabrication of components. Box-columns are suitable members for bolted structures such as welded steel structures with moment frames in two directions etc., but their continual fabrication in multi-story buildings and performing the internal continuity plate in them will cause some practical dilemmas. The details of the proposal technique introduced here, is to remove such problems from the box columns. Besides, some other advantages include new prefabricated bolted beam-to-column connections referred to BBCC. This connection is a set of plates joined to columns, beams, support, and bolts. For a better understanding of its fabrication and erection techniques, two connection and one structural maquettes are made. The present work aims to study the cyclic behavior of connection numerically. To verify the accuracy of model, a similar tested connection was modelled. Its verification was then made through comparison with test results. The behavior of connection was evaluated for an exterior connection using three different support shapes. The effects of support shapes on rigidity, ductility, rotation capacity, maximum strength, four rad rotation strength were compared to those of the AISC seismic provision requirements. It was found that single beams support has all the AISC seismic provision requirements for special moment frames with and without a continuity plate, and box with continuity plate is the best support in the BBCC connection.

The grassland regions of Australia, the Pacific and Asia share common latitudes albeit in opposing hemispheres. However, the environmental and socio-cultural context of pasture development in the subtropical and tropical regions of Australia, the Pacific Islands and Asia differ greatly. Successful technology transfer for improved productivity of grazing livestock is beset by three broad challenges; technical, logistical and socio-cultural. The technical challenge of defining the grassland environment and adapting known technology to local conditions can be successfully addressed by local technicians supported by a reservoir of appropriate international expertise. Logistical difficulties that impede provision of infrastructure and continuity of support services are the responsibility of indigenous organizations. Socio-cultural factors are fundamentally pervasive. These challenges, though outwardly obvious, require careful consideration by both donors and recipients of pasture technology to ensure success with pasture development for viable grazing industries.

The Industrial Innovation Movement, based on win-win cooperation with SMEs, is a structure that enables suppliers who have struggled with corporate growth through productivity innovation due to poor manufacturing environment and lack of innovation. To this end, consultants and technical experts will support production innovation activities to improve production methods and improve productivity through process and management consulting. The purpose of this study was to explore the driving factors of the industrial innovation movement to improve the corporate ecosystem by improving the productivity of SMEs using modified IPA. The research results are as follows. First, in order to revitalize the Industrial Innovation Movement, the CEO-related elements of the participating companies should be maintained and strengthened. The motivation, education support, innovation organizational culture, the establishment of an innovation promotion system requires centralization of efforts for improvement. Second, in order to revitalize the Industrial Innovation Movement, the consultant's ability to analyze problems and suggest alternatives should be continuously strengthened. Third, in terms of the Central Promotion Headquarters, it was found that the Industrial Innovation Movement would be successful if the public information, industrial inspection for benchmarking, and provision of various information to support innovation activities were urgently improved.

Information revolution shifted the meaning of education from traditional face-to-face education to technology integrated virtual one, namely cyber education. A new way of education, however, has not constituted its methodological standards either performance measurement scheme. The study probes the critical factors that influence students' achievement and satisfaction especially in the cyber education environment. Using hierarchical regression, important factors for students' achievement and satisfaction in the management education environment are presented. The results indicate that students' individual characteristics are relatively less influential for cyber education success. Rather, institutional supports including provision of in-depth interaction among students and with the instructor are more critical. We can infer that cyber education essentially requires three factors: in-depth interactions with instructor collaborative environment among peer students technical support from the institution.

In order to provide continuous Korea Augmentation Satellite System (KASS) services, the operation organization should continuously and systematically perform operations, maintenance, and technical activities. All subsystems of KASS, all Line Replacement Units (LRUs), and Software Replacement Units (SWRUs) should be operated and maintained continuously. In order to effectively manage these activities, it is necessary to develop an Operation Management Tool (OMT). For this purpose, operation management, operation organization, and operation activities were defined. The defined requirements were divided into general, function, interface, and database for OMT development, and functions and decision-making procedures consisting of site/asset/trouble/work order/schedule management were designed. The OMT developed by reflecting the site and asset information as well as the design content met predefined requirements. The OMT will be actively used in actual KASS operation and will evolve by continuously reflecting the additional requirements of operators. Through this tool, KASS will support continuous service provision.

The purpose of this study is to highlight overseas reductions as one of the measures to achieve Korea's 2030 NDCs, and to derive factors to promote overseas greenhouse gas reduction projects. To this end, a survey was first conducted on greenhouse gas management companies, which are the main entities for reducing greenhouse gas emissions. The contents of the survey are divided into three categories: awareness of greenhouse gas reduction projects, institutional and technical sectors, and government support and difficulties. Specifically, the perception section on greenhouse gas reduction projects examined the greenhouse gas reduction methods currently implemented or under consideration in the future. In the area of government support and difficulties, difficulties in promoting overseas greenhouse gas reduction projects were investigated. The results of the analysis using the probability selection model are as follows. First, the greater the greenhouse gas intensity, the degree of dedicated manpower, and the larger the size according to the company's business field, the higher the interest in overseas reduction projects. Second, there was discrimination in the method of reducing greenhouse gas emissions according to the size variables of the company, the degree of greenhouse gas intensity, the degree of having dedicated manpower, and the business field. Lastly, in the case of small businesses, difficulties in business promotion due to the lack of greenhouse gas reduction technology were found to be the biggest cause than other problems. Therefore, it is necessary to induce the reduction of greenhouse gas emissions by introducing foreign technologies to support greenhouse gas reduction technologies for small and medium-sized enterprises, and to provide support such as training courses for professional manpower and the operation of portals for information provision at the government level.
