The value and functionality of boundary barriers in rural villages have been neglected in the aspects as the buffer zone(boundary barrier) that links between the inside space(housing site) and the outside space(road). On this understanding, this study evaluated conservation value, economical efficiency and durability by the types and materials of the boundary barriers in rural village through Multi-attribute Decision Making. By applying to the current situations of boundary barriers on total 21 case study villages, each factor value was measured. And using Matrix Analysis Technique, the boundary barriers are classified into 4 types and the improvement ways for each type were proposed. As a result, the durability of boundary barriers in rural villages showed similarity value(more than 0.85 out of 1). But economical efficiency of those was low(less than 0.5 out of 1) and those functionalities were very lacking(about 0.3 out of 1). In the conclusion, the maintenance of boundary barriers in rural villages requires the policy that is able to complement conservation value and economical efficiency and is proper to the characteristic of each village. These renewable policies would contribute to the increase of the value of rural amenity as well as creation of economical and social value.

현행법상 28개 지목 중에서 가장 빈번하게 신설 또는 변경되는 지목은 '도로'이다. 타 지목에서와 마찬가지로, 도로의 경계는 관련 설정원칙과 법에 따라 엄격히 확정되고 있다. 그런데 이러한 경계설정기준 중 일부, 즉 지형지물을 이용한 경계설정의 원칙과 법규해석이 혼동되는 경우가 있는데, 이는 주로 도시계획 등 토지이용계획을 구상하는 단계에서 발생한다. 법적규정은 법의 제정취지가 중요한 데, 경계확정 규정의 제정취지를 잘 못 유권 해석함으로 인해 도로경계는 현실상황과 괴리되는 문제점을 발생시킨다. 이를 시급히 보완키 위해 일부 규정의 개정, 보완이 필수적이다. 법률용어인 '절토면'과 '경사면'의 적용이 통일되어야 하고, '구조물'이라는 용어는 '지형 지물'로 개선할 것을 제언한다.

A high-order spectral/boundary-element method is newly adapted as an efficient numerical tool. In this method, the velocity potential is expressed as the sum of surface potential and body potential. Then, surface potential is solved fly using the high-order spectral method and body potential is solved fly using the high-order boundary element method. Through the combination of these two methods, the wave-making problems fly a submerged sphere moving with the large amplitude oscillation are solved in time-domain. With the example calculations, nonlinear effects on free-surface profiles and hydrodynamic forces are shown and discussed.

이 글은 지난 2010년-2011년 사이에 한국사회를 충격으로 몰아넣었던 구제역의 확산과정에서 질병진단방식을 둘러싼 논쟁에 대해서 논의하게 될 것이다. 당시 구제역 방역과 질병진단 방식을 둘러싸고 다양한 사회집단들 사이에서 치열한 논쟁이 있었으며 그 중심에는 휴대용 항체/항원 간이진단키트가 논쟁의 대상이 되었다. 이 항체/항원 간이진단키트의 효용성으로 부터 사용권한까지 논쟁은 구제역 확산기간 동안 지속되었으며 특히 중앙정부를 중심으로 하는 방역당국과 지방정부와 시민단체들은 이 간이진단키트의 사용권과 병성감정권한을 둘러싸고 논쟁을 벌이게 된다. 이 논문은 항체/항원 간이진단키트를 둘러싼 의미부여방식과 기술적인 판단에 대한 각기 다른 해석방식을 설명하기 위해 "경계물(boundary objects)" 개념을 사용하여 설명할 것이다. 특히 경계물의 구성방식과 각기 다른 사회집단이 이 경계물을 포함하거나 배제하는 과정을 경계만들기(boundary making)로 해석하면서 경계물과 경계만들기 과정의 상호작용과 협상과정을 추적하게 될 것이다. 이를 통해 의학기술적 대상물인 간이진단키트가 경계물로 구성될 뿐 아니라 이를 둘러싼 사회집단의 경계만들기는 상호작용을 통해 구성되는 공구성의 과정이라는 것을 보이게 될 것이다.

이 논문의 목적은 임진정계(1712) 경계표지물에 대한 역대 실지조사기록을 검토하여, 1712~1713년에 만들어진 경계표지물의 분포를 복원하는 것이다. 허량 박도상(1713), 김우식(1883), 이중하(1885), 오록정(1907), 오소네 세이지(1907), 유건봉(1908), 일제지형도(1933), 청진교원대학 백두산탐사대(1948), 길림성 장백산 여행단(1957)의 실지조사기록을 검토하였다. 이를 통하여, 1713년 최종 완성된 임진정계 경계표지물의 분포를 도표와 지도로 제시하였다.

Since public awareness on the importance of sea is increasing, a number of states have ratified the United Nations Convention on the Law of the Sea. However several problems on marine boundary making are raising due to the ambiguity of law and importance of sea area. The purpose of this study is to find a logical principal through overall consideration on decision of baseline points which is a criteria of maritime boundary delimitation. Accordingly, this paper considers the current status, problems and measures for marine boundary making and then presents an alternative on it.

The purpose of this study are to develop a SDSS (Spatial Decision Support System) that can incorporate diverse opinions of stakeholders related the designation of protected areas (PA), and to employ the model for the readjustment of the boundary line of the Jirisan National Park of Korea. The SDSS would lead to more rational and less controversial decision-making during the expansion or removal of PA in Korea. Research methods are as follows. Firstly, to select evaluation criteria for SDSS for PA designation by using expert interview and literature survey. Secondly, to measure their preferences on the designation of additional PA or the removal of a part of PA based on the opinions of various stakeholders such as local residents, environmental groups, or public officials. Thirdly, to produce conservation priority maps based on a multi-criteria decision making technique. The SDSS would be used to rational decision making for the expansion of PA or the release of a certain part of PA by reflecting diverse preferences on biodiversity conservation and economic interest of residents. The visualization of conservation priority maps would also increase the efficiency of such decision making processes. The evaluation criteria for the expansion of PA for biodiversity conservation includes vegetation conservation value, wildlife conservation value, and the habitats of key species. The evaluation criteria for the removal of PA includes the proximity to roads and the boundary of PA, land use types, and conservation zoning of the PA. Preference weights are based on data collected from the Jirisan National Park. Both the conservation priority and removal priority maps are based on land parcels so that property rights of all parcels would be correctly represented.

A high-order spectral/boundary-element method is newly adapted as an efficient numerical tool. This method is one of the most efficient numerical methods by which the nonlinear gravity waves can be simulated and hydrodynamic forces also can be calculated in time-domain. In this method, the velocity potential is expressed as the sum of surface potential and body potential. Then, surface potential is solved by using the high-order spectral method and body potential is solved by using the high-order boundary element method. By the combination of these two methods, the wave-making problems by a submerged sphere oscillating with large amplitude under the free~surface are solved in time-domain. Through the example calculations, nonlinear effects on free-surface profiles and hydrodynamic forces are shown and discussed.

In this study, the topics for free-surface wave simulation, nonlinear hydrodynamic force, and the critical resonance frequency of so-called ${\tau}=U{\omega}/g$=1/4 are discussed. A high-order spectral/boundary element method is newly adapted as an efficient numerical tool. This method is one of the most efficient numerical methods by which the nonlinear gravity waves can be simulated and hydrodynamic forces also can be calculated in time domain. In this method, the velocity potential is expressed as the sum of surface potential and body potential. Then, surface potential is solved by using the high-order spectral method and body potential is solved by using the high-order boundary element method. By the combination of these two methods, the wave-making problems by a submerged sphere oscillating with forward speed under the free-surface are solved in time domain.

In a computational fluid dynamics, the imposition of open boundary condition has an important part of the accuracy but it is not easy to find the optimal boundary rendition. This difficult is introduced by making artificial boundary in unbounded domairs. Such open boundary requires us to ensure the continuity of all primitive variables because the nature is in continuum. Here we introduce a revised well-conditioned open boundary condition particularly in FEM and apply it to various problems-entrainment, body force, short domains.
