The previous researches have addressed the importance of service quality, customer perceived value, and customer satisfaction, but the precise nature of the interrelationship that exist between these constructs still remains a key issue. This study extend the previous researches by developing a conceptual framework linking all of these constructs, additionally including service costs and customer expected value, in a business-to-business setting. The hypothesized model indicates that delivering high quality and lower costs service can create superior customer value and results in higher customer satisfaction. The authors test the hypothesized model on data obtained from power plant operators using structural equation modeling. The results suggest that service quality displays a stronger potential for creating customer value than costs consideration. In addition, the results reveal that managing the customer expected value is important for obtaining higher customer satisfaction.

Online game business has emerged as the most lucrative entertainment industry, with over 10 million players in South Korea. The popularity of online games can be attributed to the availability of broadband network and the presence of numerous PC Bangs and around the country, which have pushed online games into the mainstream entertainment culture. The age distribution of online game players is expanding and a variety of new games are under development to target certain age groups. While the interactive entertainment market continues to expand, with many new online game publishers entering the market, relatively little is known about which factors influence online game players' behavioral intentions to play continuously n this area. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' intentions to play, flow, and the impacts of several other key game-related constructs n consumer behavioral intentions. Several types of interaction in on-line games and their relationship with the flow construct are investigated, and the resulting conceptual model is proposed. Based on data collected from online questionnaire survey, the validity of the simultaneous equation model has been tested and interesting conclusions have been developed concerning the relationships between the players' behavioral intentions to play, flow, and interactions. Other interesting results concerning game development strategy are also provided.

The modern development in design of airships and aerostats has led to unconventional configurations quite different from the classical ellipsoidal and spherical ones. This new class of air-vehicles presents a mass-to-volume ratio that can be considered very similar to the density of the fluid displaced by the vehicle itself, and as a consequence, modeling and simulation should consider the added masses in the equations of motion. The concept of added masses deals with the inertia added to a system, since an accelerating or decelerating body moving into a fluid displaces a volume of the neighboring fluid. The aim of this paper is to provide designers with the added masses matrix for more than twenty Lighter Than Air vehicles with unconventional shapes. Starting from a CAD model of a given shape, by applying a panel-like method, its external surface is properly meshed, using triangular elements. The methodology has been validated by comparing results obtained with data available in literature for a known benchmark shape, and the inaccuracies of predictions agree with the typical precision required in conceptual design. For each configuration, a CAD model and a related added masses matrix are provided, with the purpose of assisting the practitioner in the design and flight simulation of modern airships and scientific balloons.

Where no records are available at a site, a preliminary estimate may be made from relations between floods and catchment chatacteristics. A number of these chatacteristics were chosen for testing and were measured for those catchments where mean annual flood estimates were available. Although the improvement using extended data in regression of flood estimates on catchment characteristics was small, this may be due to the limitations of the regression model. When an individual short term record is to be extended, more detailed attention can be given; an example is presented of the technique which should be adopted in practice, particularly when a short term record covers a period which is known to be biassed. A method of extending the peaks over a threshold series is presented with a numerical example. The extension of records directly from rainfall by means of a conceptual model is discussed, although the application of such methods is likely to be limited by lack of recording raingauge information. Methods of combining information from various sources are discussed in terms of information from catchment characteristics supplemented by records. but are generally applicable to different sources of information. The application of this technique to estimating the probable maximum flood requires more conservative assumptions about the antecedent condition, storm profile and unit hydrograph. It is suggested that the profile and catchment wetness index at the start of the design duration should be based on the assumption that the estimated maximum rainfall occurs in all durations centered on the storm peak.

The purposes of this study were to examine and to predict the affecting factors on exercise participation of Rheumatoid arthritis Patients. The subjects were 161 adult out-patients who visited the hospital for rheumatic disease in H-university. Data were composed of self-reported questionnaire. The conceptual model of this study consisted of that personal characters(age, marriage, education, income), situational characters(pain intensity, fatigue, IADL, depression), behavioral characters(formerly exercise behavior, life-style), and cognitive-perceptional characters(perceived health status, perceived benefit, perceived barrier, perceived self-efficacy) affected directly to exercise participation. Logistic regression analysis was applied for testing model of this study. The results were as follows : 1. Personal characters(education), situational characters(pain intensity), behavioral characters(formerly exercise behavior, life-style), and cognitive characters(perceived barrier, perceived self-efficacy) were significant difference between current exercise participants(127subjects) and non-exercise participants(34). 2. Personal characters(income), situational characters(pain intensity), behavioral characters(life-style), and cognitive-perceptional characters(perceived barrier, perceived self-efficacy) were correlated to exercise participation. 3. Formerly exercise behavior, perceived barrier, and perceived self-efficacy were significant predictor of exercise participation. The logistic equation predicted overall 81.94% of this study subjects 161.

The competitive nature of enterprises requires organizations to foster an environment that encourages employee innovation that leads to profitability and customer satisfaction. Organizational innovation is influenced by several factors with employee behaviour being one of the important factors. Employees contribute in the innovation process and thus, it is important for organizations to understand employee expectations to demonstrate innovative work behaviour in order to create and maintain an innovative work culture. In the present study, a conceptual model based on culture, reward and program, training, compensations, leadership and systems was tested to assess that impact on employee expectations leading to innovative work behaviour. The study was conducted in the context of city-state of Singapore due to its significant emphasis on promoting and nurturing employee innovation. The model was tested using empirical data collected through a survey of employees in Singapore. The results indicate that while culture, rewards and training programs have a direct relationship on employee expectations to demonstrate innovative work behaviour, when considered together, leadership and systems are significantly and positively associated with employee expectations. These factors are usually under the control of organizations and can be enhanced through systematic interventions, thereby providing practice managers an avenue to improve employee innovation behaviour. The other implications of the findings and future scope are discussed.

Although the importance of the service sector has been highlighted recently, service innovation remain under-researched by scholars. Innovation research based on manufacturing sector suggests that innovation strategy varies according to the objectives of innovation and has a positive influence on firm performance. To investigate the path that links the objectives of innovation, innovation strategy used and firm performance, this study develops a conceptual model of service innovation from the literature and tests the Structural Equation Model(SEM) using STEPI (Korea's Science and Technology Policy Institute) data. We could identify the causal relationships both between the objectives of innovation and innovation strategy and between innovation strategy and firm performance in service as in manufacturing, but we also found that the results of the empirical study for the service industry, in particular, the empirical results on the relationship between the aims of innovation and innovation strategy used, are quite different from those for manufacturing.

In this study, regional frequency analysis is used to determine each subbasin drought frequency with watershed runoff which is calculated with Tank Model in Nakdong river basin. L-Monments methd which is almost unbiased and nearly normal distribution is applied to estimate paramers of drought frequency analysis of monthly runoff time series. The duration of '76-77 was the most severe drought year than othe rwater years in this study. To decide drought frequency of each subbasin from the main basin, it is calculated by interpolaing runoff from the frequency-druoght runoff relationship. and the linear regression analysis is accomplished between drought frequency of main basin and that of each subbasin. With the results of linear regression analysis, the drought runoff of each subbasin is calculated corresponing to drought frequency 10,20 and 30 years of Nakdong river basin considering safety standards for the design of impounding facilities. As the results of this study, the proposed methodology and procedure of this study can be applied to water budget analysis considering safety standards for the design of impounding facilities in the large-scale river basin. For this purpose, above all, it is recommanded that expansion of reliable observed runoff data is necessary instead of calculated runoff by rainfall-runoff conceptual model.
