To improve quality of an product We have adopted new approaches such as SPC(Statistical Process Control), CIM(compure Integreated Munufactture), QDF(Quality Development Function), etc. In spite of using these approaches, an organization should fail to achive its true goal if that organization didn't developed its cooperative quality culture which is the total of collective and shared learning of quality-related values as the organization have developed its capacity to survive in its external environment and to manage its own internal affairs. In this paper, I analyzed the current quality culture of Korea Telecom and tried to suggest how Korea Telecom develop its service quality based on the quality culture.

We need to have a universal system for the landscape architectural profession at the national level which focuses on public facilities from an aesthetic point of view and emphasizes the landscape architectural identity and traditional idiosyncrasy in Korea society. There should be established independent official positions in governmental systems in order to work practically in the field of landscape architecture concerned with ecological and environmental stability. Professionals should be acquired and diversity maintained for administrative efficiency, so that the governmental official position could create practical need and a theoretical approach to the human needs for environmental quality and ecological stability. In order to pursue the public good, we need to establish a new community and promote a global spirit, which include an ecologically stable environment developed through professional landscape architectural harmonization. The landscape architectural profession requires a new community spirit suitable to modern society, so that the Korean people continue a tradition of cooperative control of the common wealth and the labor market.

This paper present a novel 6-axis robotic base platform with force/moment sensing. The robotic base platform is made up of six loadcells connecting the moving plate to the fixed plate by spherical joints at the both ends of loadcells. The statics relation is derived, the robotic base platform prototype and the loadcell measurement system are developed. The force/moment calibrations in joint and Cartesian spaces are performed. The algorithm to detect external force applied at a working robot is derived, and using a 6-DOF robot mounted on the robotic base platform, force/moment measurement experiments have been performed.

The government is largely responsible for preventing “the tragedy of the common property”, but fisherman's effort fer an autonomous fishery control is equally required. Especially in these days of EEZ such self- regulated fishery management system should be developed and cared for as well. This study aimed to explore a proper management system for coastal fishing ground that now requires the responsible fisheries management by investigating and analysing more drastically the managerial functions of fishery right by Eochon-Gye(the smallest unit of fisheries cooperative based on a fishing village), a typical fishery producer's organization in Korea. This study also included such contents as (1) an understanding of fishery producer's organization, (2) the utilization and management system of coastal fishing ground, (3) the actual condition of fishing right distribution in Korea, (4) the fishery right management and activity of Eochon-Gye, (5) the operation and distinctive feature of fishery right in Japan, (6) the intervention and limit of fishery producer's organization for fishing ground management function, and (7) summary and proposal. We made all Eochon-Gye of the whole country an object of this study and carried out an investigation into Eochon-Gye through a questionnaire. We extracted 359 Eochon-Gye, 20% of the total 1,719 Eochon-Gye as a random sample and investigated these regions through a questionnaire by mail. The contents of the questions consist of 40 items, including six categories about the organization of eochon-gye, and fishing ground management and activities.

This paper examines the trend of restructuring and direction of management response in the Large Purse Seine Fishery. The large-scale fishing industry is one of the most popular fishing areas in the coastal area, and it has been developed by providing exclusive supplies of many types of catchy fish, such as mackerel and horse mackerel through physical productivity in fleet operations. However, the Large Purse Seine Fishery has been declining in profitability due to the deterioration of the business environment since 2000. It is at a crossroads whether it will disappear or regenerate as it is. The Large Purse Seine Fishery's current problems are: firstly, the continued deterioration of the fishery business balance and worsening labor problems, secondly, insufficient freshness management and quality control after landing, and thirdly, import competition. The fourth is the intensification of the market competition, which is the evolution of fishing variability and the increase in the proportion of small fish. The fifth is the reduction of the operating fishing ground due to the suspension of mutual fishing in Korea and Japan. To address these problems and suggest management response directions for the survival of large-scale fishing businesses is as follows. First, a sustainable production system should be established through strengthening resource management and promoting international fisheries cooperation. Second, the profitability of fishing management should be improved by introducing a low-cost supplier system and securing a stable labor force. Third, we should improve the leading and quality control of catch, improve the high value-added value of catch through brand development, and secure competitive advantage with imported produce. Finally, the government should establish a cooperative system among private sector, government, and research institutes to push ahead with these tasks and strengthen the competitiveness of the front and rear industries.

Because the development of Korea's water resources will reach its limit in the near future, preparations should now be begun to deal with problems that may come as a result. It will be too late to start preparations when the water resources have already reach their limitation and, as the preparations cannot be done in a day, it will take a long time to provide them. Now is the great turning point to accumulate our technical experiences and attain our plans gradually. The preparations against this are summarized as follows; 1)The transitory use of water should be turn into the recurrent use for the future. 2)A cooperative water control system of an area should be arranged. 3)Water saving, control of water demand, and the multiple use of water should be encouraged. To do this effectively, people should be informed of the value and rarity of water. 4)The development of freshwater reserviors at estuaries is closely related to the development of water utilization in the whole river basin. The development of water resources by the construction of freshwater reservoirs at the estuaries should be started, when the development of upstream water resources reaches their limitation. 5)The existing water utilization structures should be reorganized by water resources exchange planning, so the effective use of water in large areas be attained.

To provide an efficient link maintenance approach, we propose a cross layer medium access control (LM-MAC) protocol for multichannel cognitive radio ad hoc networks. Link establishment and reliable transmission are two key problems for a perfect link maintenance mechanism. Since the cognitive user (CU) pairs have to reestablish their links each frame, in the proposed MAC protocol, three different access modes are designed to guarantee transmission efficiency in continuous frames. To enhance the transmission reliability, each CU will create a father spectrum list (FSL) after joining in the network. FSL is divided into three groups of sub-channels with different functions to compensate the packet loss caused by the primary users' appearance and the deep fading. Meanwhile, since the transmitter and the receiver will share the same FSL, periodical cooperative sensing is adopted to further optimize the former problem. Finally, compared with the existing opportunistic multichannel (OMC)-MAC protocol, the proposed LM-MAC protocol achieves better system performance in terms of saturation throughput, continuity and access delay.

This study identified application range of SPS Code(Special Purpose Ship Code) applied to fishery training ship in Korea, and proposed counterplan for port state control. The latest contents of relevant convention was verified, used APCIS of Tokyo MOU and EQASIS provided by EU to analyze the current condition and deficiencies of port state control of fishery training ship. As the result, the SPS code equal to passenger ship and cargo ship of SOLAS convention should be satisfied with fishery training ship, and must follow ISPS Code. As for the result of record of port state control, it was confirmed that 8 fishery training ships were inspected 76 times and pointed out with 411 deficiencies in Tokyo MOU nation. 75% of deficiencies were related to SOLAS convention, and 71 times of inspections were conducted in Japan. Because it is not free from the fishery training ship, there is a need for active corresponding and preparation by enhancing local cooperative system and sharing the Internet inspection background, and need to develop and implement in-depth internship program to improve port state control counter plan for the trainees.

This paper provides a way to overcome limitations of general collaborative software development tools that completely restrict co-ownership of resources among individuals in a team oriented developmental environment. It also provides a solution for users to co-own resources and at the same time manage version control and collision problems that may occur due to the co-ownership of resources.The cooperative development support tool of developed software uses the conventional optimistic technique but employs the algorithm which is improved to reduce costs and efforts required for solving collision. The collaborative software development tool presented in this paper is made up of the classical client/server structure with the P2P(peer to peer) method which supports information exchange among individuals. This tool is developed based on open source software CVS(Concurrent Version System). Functional efficiency was confirmed by comparing it to the utility of prior existing collaborative software development tools.
