  • The manufacturing industry seeks for improvements in efficiency at the manufacturing process. This paper presents a method for effective real time dispatching for parallel machines with multi product that minimizes mean tardiness and maximizes the quality of the product. What is shown in this paper is that using the Rolling Horizon Tabu search method in the real time dispatching process, mean tardiness can be reduced to the minimum. The effectiveness of the method presented in this paper has been examined in the simulation and compared with other dispatching methods. In fact, using this method manufacturing companies can increase profits and improve customer satisfaction as well.

  • This study empirically analyzed the effects of coaches' transformational leadership on customers' exercise flow and repurchase behavior. Using two hundred seventy-five questionnaires, first, charisma, individual consideration, and intellectual stimulation had a positive effect on cognitive and behavioral flow. Second, only individual consideration increased repurchase intention. Third, cognitive flow promoted repurchase intention, but behavioral flow was not statistically significant. Lastly, there was no indirect effect on the relationship among the variables. The results may prove valuable to coaches' understanding how to enhance customers' exercise flow and may improve marketers' strategic planning decisions to attain organizational goals.

  • Using a panel data of Korea for $1979{\sim}2002$, this study investigates the determinants of the service sector employment share in Korea. In order to analyze the impact of macroeconomic factors on the service sector's employment share we estimate a simple panel model which is in line with Baumol's model. The panel GMM estimation results show that: 1) The increase in the share of service-related jobs in total employment tends to rise with GDP per capita, which confirms demand-bias hypothesis proposed by Clark. 2) We find that a crucial role in this process has been played by the productivity gap. As Baumol's hypothesis or Baumolis disease, the expansion of the employment share in services relative to industry is the direct consequence of services' lower productivity performances.

  • In order to accelerate the development of the Film Industry of Korea it is quite necessary to evaluate the value of Film Production Company appropriately and then to activate investment through its work of estimating. So far however, the researches on the evaluation model for Korean Film Production Company has been rarely conducted considering those of any other advanced countries. Therefore, the appropriate valuation model among numerous valuation model for film firms has not been provided until now. So the purpose of this article is to suggest the rational decision making criteria for the investment of Film Production Company by comparing with DCF, FCF, and ROV model through the empirical research focused on case study. According to the results of research, ROV model is more efficient and available comparing other two methods.

  • The neutrichemical analysis of hempseed from Cheungsam was performed in order to apply hempseed to food industry. Cheungsam hempseed was mainly composed of crude fat (30.52%) and protein (30.02%). The hempseed fat contained about 88% of polyunsaturated fatty acids, and the omega-6 to omega-3 ratio was determined to be approximately 3:1. Hempseed from Cheungsam was rich in essential amino acids. Moreover, hempseed protein from Cheungsam, extracted by acid-base precipitation method, showed free radical scavenging activity. The results suggest that Cheungsam hempseed protein could be utilized as a superior source of protein nutrition.

  • To understand current status for the utilization of Korean military specifications(KDS) and other standards/specifications in munitions companies, we have surveyed 150 companies mainly related with electrical and electronic industry. Most of the companies have expected that the harmonization of KDS and KS would bring a positive effect on their business, especially from the point of quality control, productivity increase, the reduction of expenditure for standard management and so on. This survey result will help to build more user-friendly management system for KDS as well as KS.

  • OSEK/VDX is a joint project aiming at an industry standard for ECUs in vehicles and OSEK OS is a real-time operating system that meets OSEK/VDX specifications. In this paper, we suggest an implementation of task switching and interrupt handling mechanisms of OSEK operating system based on ARM processors. Considering the requirements of OSEK OS and characteristics of ARM processor, we have designed task switching and interrupt handling mechanisms. For evaluating the validation of the suggested mechanisms, we have checked the functional correctness on an experimental embedded board with ARM processor and calculated the time of task switching and interrupt handling.
