To restore urban water cycle, it is necessary to improve domestic laws and regulations related to LID(Low Impact Development), which has been successfully applied to foreign countries. Thus, this study has intended to evaluate domestic legal systems related to space and environmental planning and to suggest directions to improve laws and regulations related to space and environmental planning toward extended application of LID in Korea. To reach this goal, this study has analyze the legal and institutional status of the foreign countries where LID has currently been applied, to derive the factors that laws and institutions are required to support LID based on the above analysis, to evaluate domestic laws and regulations related to space and environmental planning, and to suggest directions to improve the laws and regulations. After the evaluation, this study has found the following results. First, it was found that the concept and basic principles of LID and LID planning and associated methods were no longer mirrored in the space planning-related laws and regulations. However, these problems are not confined to LID, and result from thefailurein applying environmental planning to space planning overall. Second, it was revealed that the environmental planning-related laws and regulations defined the terminologies and targets of LID and suggested different measures to improve LID-related policies differently depending on the backgrounds ofenforcing thelaws and regulations and on environmental properties. Finally, this study has suggested the directions to improve laws and regulations related to space and environmental planning as follows. First, it is necessary to enact a law to support the extended application of LID. Second, the law to be enacted should be connected to laws, enforcement ordinances and regulations, and guidelines related to space planning. Third, environmental benefits provided by both structural and non-structural techniques of LID should be quantitatively measured.

This article aims to explore the connectivity and centrality between environment law and spatial law, where make implications in environmental planning. To achieve it, we used Network Analysis(NA) as a tool for analyzing the connectivities. 52 environmental Laws and 29 Spatial Laws are selected and used for this analysis. This study also attempts to explain the phenomenon through quantitative study rather than qualitative research. This paper is methodologically the first attempt to Environmental Law study, which will help to understand the structure of complex Environmental Law. The result of the network analysis for connectivity between Spatial Law and Environmental Law demonstrates that two laws are in less mutual relationship with each other. It also supports that Environmental Law and Spatial Law need to be closely connected with each other for effective environmental management.

Graphplan 계획기에서 유래된 계획 그래프는 탐색에 매우 유용한 휴우리스틱을 손쉽게 얻을 수 있는 수단이다. 본 논문에서는 전향 상태 공간 계획방식을 정의한 뒤, 이 계획방식에 적용 가능한 계획 그래프 기반의 휴우리스틱 계산법들을 소개한다. 또 본 논문에서는 각 휴우리스틱 계산법이 갖는 특징을 정리하고 이들이 계획생성에 미치는 효과를 실험을 통해 비교, 분석해본다. 또한 이러한 전향 상태 공간 탐색 알고리즘과 휴우리스틱 계산법을 토대로 본 연구에서는 전향 상태 공간 계획기인 JPLAN을 구현하였고 그 구조에 대해 설명한다.

본 논문은 해양공간계획법에 근거한 해양에서의 다양한 용도 경합이 예상되는 울산 부유식 해상풍력발전단지 조성사업에 대하여 살펴보고자 한다. 해양공간계획법에 따르면 다양한 용도가 중첩되는 경우, 자연환경, 사회경제적 여건 및 주변 해역의 이용 및 보전 현황 등을 고려하여 관리의 우선순위를 정해야 한다. 이에, 해상풍력발전단지 설립에 따른 해양환경 및 천연자원 영향성 평가의 경제적 피해액을 추정한다. 이는 해양공간계획 시, 용도지정 우선순위를 정할 때 객관적 자료가 될 수 있고, 나아가 효율적인 풍력발전단지 운영을 위한 기초 자료가 될 것이다.

Die Arbeit beschaeftigt sich mit dem Entstehungsprozess und dem Organisationssystem der Raumordnung und Paumplanung in der Bundesrepublik Deutschland. Selbstverstaendlich hat die deutsche Raumplanung eine laengere Geschichte und eine besondere Tradition, entstand die heutige einheitliche Raumordnungspolitik erst im Jahr 1965. Im Grunde hat die Raumplanung immer eine ausgewogene Raumentwicklung aufgesucht und ist in den infolge des foederativen Systems gerade komplizierten Verwaltungsaufbau integriert.

This study investigates the optimum structural design of space truss considering global buckling, and is to obtain the minimal weight of the structure. The mathematical programming method is used for optimization of each member by member force. Besides, dynamic programming method is adapted for consideration in snap-through buckling. The mathematical modeling for optimum design of truss members consists of objective function of total weight and constrain equations of allowable tensile (or compressive) stress and slenderness. The tangential stiffness matrix is examined to find the critical point on equilibrium path, and a ratio of the buckling load to design load is reflected in iteration procedures of dynamic programming method to adjust the stiffness of space truss. The star dome is examined to verify the proposed optimum design processor. The numerical results of the model are conversed well and satisfied all constrains. This processor is a relatively simple method to carry out optimum design with consideration in global buckling, and is viable in practice with respect to structural design.

Environmental conservation plan, notwithstanding their feasibility and potential utility in construction of environment-friendly spaces, has long been perceived in practice as "declarative" and a "formality." Such perceptions are largely the result of the failure to provide spatial planning that is directly relevant to development of the space in question, and to sufficiently interconnect with urban development plan. This demonstrates the need for ways to link disparate plans, i.e. to enact "spatial environment plan." In response to these issues, this study proposes the systematization of spatial environment data as a necessary prerequisite to the establishment of spatial environment plan, which would provide both linkages with other plans, and ensure the applicability of environmental conservation plan. To this end, this study analyzed existing environmental data, and then proposed systems for links with spatial environment plan. In respect of this, the study examined spatial data systems, and then classified applicable spatial according to each environmental medium. The study also produced spatial information and planning items that can be included in spatial environment plans for each of the nine environmental media, and then constructed a system that could link the existing spatial information system, current spatial environment data, and spatial environment management plan. Furthermore, the study proposed matters for improvement in the construction of spatial environmental data to ensure the activation of spatial environment plan. The construction of a systematic spatial database, by facilitating the smooth establishment of spatial environment plan, can enhance and upgrade environmental conservation plan, while contributing to enhanced linkages with related spatial plans.

중심합성계획(central composite design: ccd)은 반응 표면이 곡면적인 특성을 나타낼때 반응 공간을 추정하기 위해 사용되는 실험계획이다. 반응공간이 2차 회귀모형으로 나타나는 경우에 반응곡면의 변화량을 알기 위해서는 변수의 수준이 3이상이 되어야하는데 ccd는 적은 횟수의 실험으로 곡면을 효과적으로 추정하기 위해 2$^{k}$ 요인실험에 추가적으로 중심점(central point)과 축점(axial point)을 표본점에 포함시키는 계획이다. 본 연구에서는 시뮬레이션 실험에서 반응변수가 2차 회귀모형으로 근사되는 경우에 cod를 이용하여 관심 성과치의 반응표면을 추정하고자 한다. 일반적인 실험에서와는 달리 시뮬레이션 실험에서는 두개의 표본점(인자 수준의 조합)에서 분석자가 공통 난수계열(common random number series)을 부여하여 시뮬레이션 시스템 요소의 변화과정을 유사하게 통제할 수 있다. 일반적으로 공통난수법(common random number method)에 의해 얻어지는 두 표본점에서의 반응변수는 서로 양의 상관관계를 가지며 대조 난수(antithetic random number)에 의한 두 반응변수는 음의 상관성을 가지는 것으로 알려졌다. 본 연구는 ccd의 표본점에 공통난수와 대조난수 법을 이용하여 회귀모형의 파라미터를 효과적으로 추정하는 방법을 조사하고 이를 (s, S) 재고관리 모형에 적용하여 그 효율성을 평가하고자 한다.
