While the zoning system has been developed based on the rationale of separated and specialized land uses to prevent negative externalities in the modern industrial era, the emergence of office-based new industries in the post-industrial era rather encourages mixed land uses to create agglomeration economies. This study aims to find historical basis to justify the reform of zoning system to promote both specialized and mixed land uses. When the zoning system was first introduced in Japanese colonial period by Chosun Planning Ordinance enacted in 1934, Special District within Manufacturing Area, and later within Residential, Commercial, and Mixed Areas respectively was institutionalized for specialized land uses, though it was not actually designated. When City Planning Law was enacted in 1962, Special District was substituted by Exclusive Areas (Exclusive Residential Area, Exclusive Manufacturing Area). Meanwhile Undesignated Area was designated for mixed land uses by Chosun Planning Ordinance, and later it was converted mostly into Mixed Area and partially into Green Area. Finally Mixed Area was substituted by Semi-Areas (Semi-Residential Area, Semi-Manufacturing Area) by City Planning Law in 1962. These demonstrate that Korean zoning system needs to revive the tradition that clearly promoted both specialized and mixed land uses.

This paper presents a process planning system that will generate and verify assembly sequences of block assemblies. It consists of a CAD interface system and an assembly sequence planning system. In developing this system, we used an open architecture CAD kernel for the CAD interface system, for visualizing the CAD model and the assembly sequences, and an expert system shell for the assembly sequence planning system. This paper also proposes a framework for the integration of all the steps required to automate the procedures, from design to production. The process planning system is demonstrated by a simple example.

This paper is part of an ongoing project of KEPCO; 'A Study on Criteria and Standards for Transmission System Planning', The objective of this project is to develop the standards and procedures for transmission system planning. This involves reviewing published literatures, other documents of existing criteria and procedures, and various case studies of advanced countries which are already under the competitive electricity industry. This paper presents the result of evaluating Korean Power System as a pre-study for developing the Planning Standards of Korean Power System. For this, WSCC/NERC's performance criteria for planning transmission system, and KEPCO's 'Long Term Transmission System Planning Criteria' are considered. By doing this, the level of performance criteria which should be applied to Korean Power System and the detailed procedures which would be used in system test were reviewed.

The purposes of this paper are first, to develop and adapt auditing methodology of rural amenity resource investigation and second, to propose strategic planning of amenity web data base system. Relating with auditing methodology, we make the life cycle of rural amenity resource investigation based on value chain method. we make 8 stage of auditing process and 105 auditing items in details. We adapt these guidelines in real world and then improve developed methodology. Therefore we expect to promote the quality and accuracy of investigation project using these guidelines. Relating with blue print of strategic planning, we first analyse external environment about Competitors, Suppliers, New entrants, Buyers, Substitutes with 5 force model for amenity information system. We second make the blue print of strategic planning of amenity web data base system project. Then we propose the FIRST, BEST, MOST strategy of amenity web data base system and the web hub system.

본 논문에서는 혼합정수 선형계획 법을 이용하여 장기 전력계통 계획수립시 최적의 설비를 투자할 수 있는 기법을 제안하였다. 발전설비와 송변전설비는 하나의 망으로 연결되어 상호 보완적 영향을 주기 때문에 계통계획시 두 설비를 동시에 평가하는 것이 무엇보다 중요하다. 또한 계획기간 전체에 대해 투자비를 고려하여 비용을 최소화해야 한다. 이를 위해 선형계획법을 계통계획에 도입하여 최소비용의 투자비를 가지고 공급 신뢰도 기준를 만족할 수 있는 최적 장기 전력계통 계획 수립기법을 개발하였다. 개발된 기법을 Garver 6모선 계통 및 제3차 전력수급기본계획에 대해 모의하여 결과의 타당성을 검증하였다.

The objective of supply chain planning is to satisfy the requirements for minimizing inventory costs, transportation costs, and lead times throughout the supply, production and distribution stage dispersed geographically. Therefore, the supply chain planning system should have functionalities to resolve complex optimization problems that have characteristics of multi-stage and multi-product. Ant the system should also support collaborative decision making among distributed business partners. In this study, we proposed a distributed architecture for the supply chain planning system. To do this, we analyzed functional requirements by using IDEF-0(ICAM Definition-0) methodology, defined required components, and designed each component by using object-oriented methodology. We implemented a prototype system based on CORBA (Common Object Request Broker Architecture) to show that the proposed distributed architecture based on component technology is feasible and can solve supply chain planning problem collaboratively.

본 논문에서는 컨테이너 터미널의 운영 계획들을 통합된 환경에서 수립할 수 있도록 지원하는 시스템 개발 사례를 소개한다. 과거 터미널 운영 계획이 선석, 장치장, 선적계획 등 단위 계획별로 계획 시스템이 따로 개발되었던 점을 보완하여 각 계획간의 연계 작업 및 재조작이 가능할 수 있도록 하나의 통합된 시스템으로 설계하고 구현하였다. 개발된 시스템은 통합 운영 계획 작성, 사용자 편의성을 고려한 Interface, 규칙에 의한 자동 계획 및 오류에 대한 경고, 계획 수정의 용이성 등을 특징으로 하고 있다.

Under the influence of nuclear radiation, the reliability of steam generators (SGs) is an important factor in the efficiency and safety of nuclear power plant (NPP) reactors. Motion planning that remotely manipulates an SG mobile tube-inspection robot to inspect SG heat transfer tubes is the mainstream trend of NPP robot development. To achieve motion planning, conditional traversal is usually used for base position optimization, and then the A^* algorithm is used for path planning. However, the proposed approach requires considerable processing time and has a single expansion during path planning and plan paths with many turns, which decreases the working speed of the robot. Therefore, to reduce the calculation time and improve the efficiency of motion planning, modifications such as the matrix method, improved parent node, turning cost, and improved expanded node were proposed in this study. We also present a comprehensive evaluation index to evaluate the performance of the improved algorithm. We validated the efficiency of the proposed method by planning on a tube sheet with square-type tube arrays and experimenting with Model SG.

Planning Support System (PSS), an alternative framework of computer-aided planning system combining geographic information system (GIS), urban models, and visualization tools, has been actively researched and applied in many developed countries. This paper introduces a PSS-based land use change model, What if\ulcorner PSS, by applying it to Chongju City, Korea. This model application study used the spatial database, Restricted Development Zone (RDZ), and other hypothetical land supply- and demand-related policies of Chongju City. The collaborative PSS model supported land use planning process by helping users to speedily and easily create and test policy-oriented scenarios. The study found that the fully operational PSS model was readily applicable and useful to Korean local land use planning. The paper discusses the conceptual model framework, data requirement, application process, model output, and practical usage. This study would be considered as a prototypical approach of PSS-based land use plan making for Korean cities.
