In this study, we propose a method of optimal placement technique of artificial reef considering characteristics of sea areas and provide basic data for efficient budget execution. In addition, we will contribute to increasing the economic efficiency by improving the fisheries productivity by suggesting the scientific basis for the policy data and the increase of the catch through the resource creation based on the ecological information about the biology. Especially, in order to establish the effective disposition (optimum separation distance) of artificial reef considering characteristics of biological and engineering factors, it is necessary to review the artificial reef installation management regulations and investigate the biological effects of artificial reef facilities, is needed. Through this, it is expected that the ground data of the direction of the policy promotion will be derived by suggesting the placement condition of the artificial reef complex which can maximize the resource composition effect according to the target fish species.
본 연구에서는 고밀 시가화지역 내 녹지들의 경관생태학적 특성과 연결성을 분석함으로써 잠재적인 녹지패치들의 활용가능성을 평가하고, 이를 통해 생활권 내 녹지 네트워크를 형성하기 위한 도시정원의 도입 방안을 제시하고자 한다. 이를 위해, 서울시에서 공원 서비스 소외지역 및 중점녹화지구로 분류된 역삼동 일대를 대상지로 선정하였다. 우선, 대상지 일대 고밀 시가화지역 내 녹지의 현황을 가로녹지, 개인정원, 자투리공지, 공원, 옥상정원의 5개 항목으로 분류하여 파악하고, 녹지 네트워크 분석 및 잠재적 녹지의 가치를 평가하기 위하여 FRAGSTATS를 통한 경관지수 분석 및 다중버퍼생성분석을 통한 연결성평가를 실시하였다. 연구결과, 대상지 내 녹지면적은 가로녹지, 개인정원, 자투리공지, 공원, 옥상정원의 순으로 분포되어 있었다. 녹지의 유형별 특징으로는 가로녹지의 경우 핵심지역면적 (TCA)이 1,618m2로 가장 높은 값을 보여 선형 연결 녹지임에도 공원(1,128m2)에 상응하는 크기를 보였고, 개인정원의 경우 패치의 모양이 불규칙하면서도(ED=78.1m/㏊), 최근린 평균거리가 33.9m로 낮아 사유지내에서의 자유로운 정원 조성을 통해 고밀 시가화지역의 녹지군을 형성할 수 있음을 나타내었다. 자투리공지의 경우 대상지 내 가장 고루 분포하는(LPI=5.7%, SHEI=0.9) 녹지유형이나 외부교란에 노출되어 있어(TCA=66m2), 이를 고려한 정원으로의 활용 방안을 시사하였다. 대상지 내 녹지네트워크 형성에 있어서도 50m의 버퍼 범위를 연결녹지로 상정한 경우 전체 대상지 의 84%가 소규모 녹지네트워크에 의해 커버되는 것으로 나타났으며, 자투리공지의 연결만으로도(27%) 가로녹지(26%) 조성에 상응하는 네트워크 구축효과가 기대되었다. 이에, 주택지역을 중심으로 다양한 활동이 가능한 자투리 공공녹지 에 지역기반의 커뮤니티 가든 등 도시정원 조성을 장려하고, 가로녹지, 개인정원, 옥상정원도 동시에 적극 활용함으로써 고밀 시가화지역 내에 녹지네트워크를 효과적으로 구축할 수 있다고 판단되었다.
국제 교역의 발달 및 기후변화에 의해 외래병해충의 국내 침입 및 토착화 가능성이 점차 증가하고 있다. 이러한 외래 식물병해충은 국내의 농업환경과 자연생태계 전반에 걸쳐 피해를 줄 수 있기에 선진화된 검역기법을 통한 조기차단과 침입한 병해충에 대한 효과적인 방제가 매우 중요하다. 그러나 국내로 유입가능성이 높은 외래병해충에 대한 연구시설과 이에 대한 건축기준이 갖추어져 있지 않아 살아있는 상태의 병해충을 대상으로 선제적인 연구를 진행하기 어려운 상황이다. 따라서 해외병해충 연구시스템을 구현하기 위해 필요한 밀폐 연구시설의 건립기준을 외국의 유사시설을 바탕으로 고찰해 보았다. 이를 위해서는 인축에 유해한 병원체를 연구할 수 있는 넓은 의미의 생물안전시설(Biosafety level 3, BL-3)가 가지고 있는 밀폐 기준을 바탕으로 해충 연구를 위해 건축된 USDA-APHIS BL3 시설을 기반으로 해충의 유출 가능성을 차단할 수 있는 물리적 건축기준과 제도적 운영기준이 동시에 마련되어야 할 것이다.
국립생물자원관에서는 ‘국가 생물자원 종합 인벤토리 구축 사업’의 일환으로 한국 분포 생물종의 실체를 확인하고 분류학적 정보 및 화상 자료를 포함한 표본 정보를 확보하여 database를 구축하는 ‘국가 생물종 확증표본 시스템 구축’을 수행하였다. 따라서 한국 분포 생물종에 대한 국내 소장 표본뿐만 아니라 외국에 반출되어 있는 표본까지도 광범위하게 조사해야 한다. 현 결과는 전체 생물 중 곤충강을 대상으로 한 결과에 대해 보고하고자 하였다. 2016년까지 국가 생물종 목록 기준 한국에 기록된 곤충종수는 16,993종이며, 이 중 10,693종(63%)에 대한 확증표본 정보를 확보하였다. 그러나 나머지 6,300종은 대부분 분류학적 난분류군이며, 희귀종이나 감소 추세종으로 추정되어 각 분류군 전문가의 분류학적 소견이 필요한 상황이다. 현재 국립생물자원관에서는 전 곤충종에 대한 확증표본 확보에 중점을 두고 있으며, 이에 대한 실체 및 정보 확보가 완성된다면 국가생물주권확보의 근간이 될 것으로 사료된다
Semiconductor is one of the biggest export items in Korea and one of future foods. In this study, the development of the product due to the repetition of the engineer mistakes repeatedly occurred due to the experience and habit of the individual in the semiconductor design process until now, resulting in an increase in the development period of the product and the economic loss of sales. As a result, the need for database of engineers' knowledge and know-how has emerged. This study investigate show to integrate and utilize data that is not managed on On/off-line for semiconductor knowledge and know-how. To do this, we intend to construct a RCT(RootCauseTracker) system that enables statistical analysis of the data on design failure accumulated over the previous year in any company.
In order to secure competitiveness of companies in the semiconductor industry, state management of equipment is one of the most important key factors. Particularly, after carrying out preventive maintenance (PM) work to maintain the best equipment condition, process reliability inspection is carried out. This work must be performed manually by the intervention of the operator. This inspection work is becoming more and more difficult due to the difficulty of the manufacturing worker, the increase of the simple repetitive workload, and the increase of the inspection items for the engineer, as the condition and the procedure continuously change as the semiconductor scaling down. Therefore, we would like to carry out an empirical study on the construction of an automatic inspection system in order to carry out the more reliable and efficient inspection procedure by eliminating the problems and unreasonableness of the past based on the investigation and analysis of the work procedures and conditions of the existing manual method.

The scope of this study is the construction conformity assessment system according to the new paradigm of construction management To minimize the differences between domestic and international state, construction Conformity Assessment is subdivided into system certification and product certification. For the former, WASCON(Worldwide Assessment System of Construction Quality Maturity Stage) is applied. For the latter, AQUA(Advanced Quality Assessment System) was developed and adopted to model project for demonstration. Both systems are designed to enable quantified rating, integrated into PQCS(Project Quality Certification), which is an advanced project quality certification system. The construction work observing PQCS will gain quality score on its own quality certificate(Quality mark on construction itself or facilities is also available, if needed or preferred by customers). This Quality Rating System will inspire and encourage any related parties. PQCS score would let supplier/constructor recognize how much themselves are operating effectively and efficiently, offering them the opportunity of redeeming their weaknesses.
Artillery fire power due to effectiveness which is hard to predict well-planned and surprising attack can give a fear and shock to the personnel and is a very core weapon system and takes a critical role in wartime. Therefore in order to maximize operational effectiveness, Army required protecting artillery and takes a quick attack action through rapid construction of artillery’s positions. The artillery use artillery’s position to prevent exposure by moving to other position frequently. They have to move and construct at new artillery’s positions quickly against exposing existed place by foe’s recognition. These positions should be built by not manpower but engineering construction equipment. Because artillery positions have to protect human and artillery equipment well and build quickly. Military engineering battalion have lots of construction equipment which include excavator, loader, dozer, combat multi-purposed excavator, armored combat earthmover dump truck and so on. So they have to decide to optimal number of Team combining these equipments and determine construction sequence of artillery’s position in operational plan. In this research, we propose to decide number of Team efficiently and allocate required construction’s positions for each Team under constraints of limited equipments and time. To do so, we develop efficient heuristic method which can give near optimal solution and be applied to various situation including commander’s intention, artillery position’s priority or grouping etc. This heuristic can support quick and flexible construction plan of artillery positions not only for using various composition’s equipment to organize Teams but also for changing quantity of positions.
