This paper addresses the critical factors of customer satisfaction between department store which is characterized as a good service quality and discount store which has a competitive advantage on price dimension. The result showed that overall satisfaction of department store was slightly higher than that of discount store. Also, it was found that only service quality was a good indicator as a customer satisfaction of department store. However, overall satisfaction of discount store was significantly affected by both price and service quality. The study contributes to our understanding of how department store and discount store develop KSFs(key success factors) of customer satisfaction.

The interference situation for the satellite networks using non-geostationary satellite orbit (NGSO) is more complicated than the situation between geostationary satellite orbit (GSO) networks because of the time varying orbital characteristics of NGSO systems. Most of frequency bands are allocated to fixed-satellite service and liked-service in co-primary basis. In this paper, the sharing criteria between NGSO/FSS systems and HDFS (High Density Fixed-Service) are examined.

Several studies have investigated the success of ASP(Application Service Provider) from various perspectives. This study, thus, investigated factors affecting ASP effectiveness in various literature relevant ASP and outsourcing. By applying the basic ideas of the IS success model, this study proposes a research model of the factors affecting the success of ASP, in term of internal factors(Top Management Involvement, User Participation, IS Maturity) and external factors(Transaction Reliability, Service Reliability, System Trust Security). The proposed model is expected to help both researchers and practitioners extend their understanding of the success factors of the ASP effectiveness.

In this paper, We develop performance evaluation model for Twin fork Automated Storage/Retrieval systems. The system is modeled as a modified bulk service queueing system consisting of one exponential server with limited system capacity. The differance between this model and general bulk service queueing model is the inequality of transition service rate of each stage. The ejective of this model is to provide system characteristics for Twin fork AS/R system design problems, which are the number of customers in system, wait time in system and queue, the system queue size.

Water lubricated guide bearing was newly released and has been applied to actual hydro turbines with vertical shaft. As a result, they can have not only high bearing performance but environmental advantages in meeting the demand for reducing river pollution by oil leakage from oil lubricated guide bearing. The PTFE composite guide bearing was tested by experimental equipment operated under conditions similar to those of actual hydro turbines. Circumferential and axial tilting bearing segments help to improve the bearing performance and efficiency due to low friction loss in the bearing system. Furthermore, bearing cooling systems could be eliminated and maintenance periods could be extended, thus the initial investment and operating costs of the hydroelectric power plant are reduced.

The study of public health systems is an important, but very difficult task. The concept and functions of public health systems are influenced by the views, interests, and influence of the various stakeholders belonging to public health systems and broader social, economic, political, and environmental sectors. To define public health system with conceptual clarification, we must take into account the dynamic and complex aspect of the public health system. This paper reviews health systems and public health systems literature to suggest the concept, goals, and functions of public health systems. In addition, this paper recognizes some challenges, such as leadership and management, resource development, economic support, and service delivery to strengthen public health systems for improving health and well-being of population.

In this paper South Africa is divided into strong wind climate zones, which indicate the main sources of annual maximum wind gusts. By the analysis of wind gust data of 94 weather stations, which had continuous climate time series of 10 years or longer, six sources, or strong-wind producing mechanisms, could be identified and zoned accordingly. The two primary causes of strong wind gusts are thunderstorm activity and extratropical low pressure systems, which are associated with the passage of cold fronts over the southern African subcontinent. Over the eastern and central interior of South Africa annual maximum wind gusts are usually caused by thunderstorm gust fronts during summer, while in the western and southern interior extratropical cyclones play the most dominant role. Along the coast and adjacent interior annual extreme gusts are usually caused by extratropical cyclones. Four secondary sources of strong winds are the ridging of the quasi-stationary Atlantic and Indian Ocean high pressure systems over the subcontinent, surface troughs to the west in the interior with strong ridging from the east, convergence from the interior towards isolated low pressure systems or deep coastal low pressure systems, and deep surface troughs on the West Coast.
