The objective of this study was to investigate the problems and benefits associated with the implementation of HACCP on livestock product of plants in Korea. The survey was carried out by randomly selecting 115 HACCP accredited meat processing plants, all across the country. A total of 105 complete responses were selected for analysis. The results were as follows: approximately 60% of the respondents employed less than twenty workers. The average period of operating HACCP system was 3.4 years. The respondents replied that the major incentive to implement the HACCP system was to improve hygiene management ability. More than half of the respondents (59.05%) claimed that the implementation of the HACCP system cost less than 400 million won, and the highest investment in terms of cost was the freezer/refrigerator. In the preparation period taken to implement the HACCP system, the 6-12 mon category had the highest percentage (55.24%). Most respondents replied that there was an increase in the customer satisfaction, plant image and turnover, after HACCP implementation (p<0.05). A total of 98.09% of respondents had the opinion that their plant workers had improved in their understanding of food hygiene by HACCP implementation (p<0.05). Approximately 79% of respondents indicated that customer complaints decreased, as a result of HACCP implementation.

The Phone Voting service allows subscribers to propose a voting through a telephone, and enables them to survey public opinion using telephone network. The demand on this service is growing faster and demands will be increased much more. It makes the bust traffic at the Toll SSP system on Intelligent Network because of the temporary bust traffic congestion on the Toll SSP compared to the normal call traffic. This paper will show what the problems and the causes are, and how we can solve them. The solution to these problems is an implementation of the SSP function on the Local Excange for the PV service.

The convergence rate of a numerical procedure based on Schwarz Alternating Method (SAM) for solving elliptic boundary value problems depends on the selection of the interface conditions applied on the interior boundaries of the overlapping subdomains. It has been observed that the Robin condition (mixed interface condition), controlled by a parameter, can optimize SAM's convergence rate. In [8], one formulated the twolayer multi-parameterized SAM and determined the optimal values of the multi-parameters to produce the best convergence rate for one-dimensional elliptic boundary value problems. Two-dimensional implementation was presented in [10]. In this paper, we present an implementation for threedimensional problem.

This paper analyzed four different perspectives on health care reform in Korea in terms of the basic values, formulated problems and reform plans, implementation methods, and supporting groups. The medical security plan was insisted by social security specialists and social activists focusing on the integration of medical insurance coops in order to enhancing equity and right of the people. However, its perspective was limited to promoting security instead of reforming health care system. The government proposed the health care reform plans in 1994 and in 1997, focusing on promoting efficiency by remedying many problems in health care delivery system. However, its implementation was not successful due to the lack of organizational and financial supporters. Recently, two opposite proposals were issued. The market reform plan paid attention to revitalizing the market function to promoting efficiency by allowing hospitals to treat private patients instead of applying the medical insurance regulation. The government reform plan focused on intensifying governmental planning and intervention in the health care sector in order to removing inefficiency and promoting equity with the supports of social activists and labor unions. Finally, this paper proposed an alternative plan to promote harmonious social relationship between actors in the health care system.

Recently, the advent of World-Wide-Web(WWW) and the explosive popularity of the Internet gave birth to collaborative applications which were enabled by computers and networks as their primary media. And the progress of 3D computer graphics enabled collaborative application with 3D virtual environments or distributed virtual environments. In this paper, we explain our implementation of Share collaboration engine and Virtual Architectural Engineering 2000 (VAE2000) system which is our pilot application implemented with Share collaboration engine. And we explain problems presented by our experiments with VAE2000 system. For those problems, we design our new middle-ware system, SHINE(SHared INternet Environment). The SHINE proposes new concepts and approaches for collaboration with 3D objects in a virtual world.

Purpose The purpose of this study is to introduce U-CAAM(University-Competence Assessment & Accreditation Management) system which is designed to effectively manage extracurricular education programs in a university. Extracurricular education is known to be very important to increase core competences of students who have different levels of knowledge and skills as well as career plans. Design/methodology/approach In this study, U-CAAM system which is designed and developed to tackle the problems related to university extracurricular education is introduced. The case will give meaningful insights to those universities which consider to have similar environment. The survey is conducted to show the need to a systematic management environment to effectively manage the problems with operating extracurricular education programs. Findings The survey result shows that universities understand the need to manage extracurricular education programs effectively. Implementation of U-CAAM provides the practical insights related to this issue.

This research deals with the basic ideas and implementation used for developing competitive advantage in the market they serve. The market to which a company belongs is continuously evolving, not static. Therefore, the company is required to adopt a suitable strategy in the market it serves. Marketing strategy establishment requires continual adjustment in the strategy content and redirection in organizational actions to address emerging market problems and opportunities. Much of the strategic implementation is characterized by firefights aimed at solving emerging, unforeseen problems. The concept of strategy was originally introduced to provide companies with a rational means of coping with environmental changes. An old Oriental proverb said that "knowing myself and then understanding others is the best way to success". In line with the proverb, the starting point of marketing strategy establishment for the competitive advantage is to understand the activities of a company wholly. After analyzing the scope of its activities, a company has to understand the market structure, to review competitive environments, to formulate the base of the competitive strategy and to adopt differentiation strategies for obtaining the competitive advantage.

The incorporation of radiation from massive stars is essential for modeling the dynamics and chemistry of star-forming clouds, yet it is a computationally demanding task for three-dimensional problems. We describe the implementation and tests of radiative transfer module due to point sources on a three-dimensional Cartesian grid in the Eulerian MHD code Athena. To solve the integral form of the radiation transfer equation, we adopt a widely-used long characteristics method with spatially adaptive ray tracing in which rays are split when sampling of cells becomes coarse. We use a completely asynchronous communication pattern between processors to accelerate transport of rays through a computational domain, a major source of performance bottleneck. The results of strong and weak scaling tests show that our code performs well with a large number of processors. We apply our radiation hydrodynamics code to some test problems involving dynamical expansion of HII regions.
