Selection of proper root barrier as destination part of greening is very important in Root penetration resistance plan. To select proper root barrier, it need to understand composition of greening part, size, kind of plant, connection with waterproofing layer. In this point of view, we have establish greening on the roof or concrete structure, not been understand the structural mechanism. It means that we misunderstood about purpose of greening and using it. So, chosen materials and construction method was not proper for greening, it caused water leakage and decrease performance of concrete structure. Therefore, we examine the practical use of copper sheet considering environmental condition for green roof. Watertightness by water of greening part, root penetration resistance test by root penetration, bacteria resistance by must or bacteria in soil, chemical resistance by rain and chemical agent of fertilizer, and load resistance by soil depth, sire of plant. These suggested test methods could be referred as guideline to test in green roof system because of not exist any performance appraisal guideline or standard. Consequently, it should be analysis as technical and institutional subdividing test methods and it need to study constantly as varied angles.

공시지가 유사가격권의 경우는 비교표준지 선정시 지침상에서 상당히 중요한 요소로 취급되고 있으면서도 실제적으로는 범위와 적용에 관해서 모호한 개념상의 규정을 두고 있다. 이러한 원인에 기인하여 비교표준지의 자동 선정이나 공시지가의 자동 산정에 있어 많은 문제점으로 작용하고 있다. 따라서 신속하고 정확한 비교표준지의 선정과 향후 지가산정 일련의 과정을 전산화하기 위해서는 자동화된 방식으로 유사가격권을 구획할 수 있는 객관적이고 합리적인 방법론이 필요하다. 본 연구에서는 개별공시지가 산정시 유사가격권 설정의 문제를 해결하고자 평균연결법과 K-means 혼합클러스터링 기법을 활용하여 유사가격권을 설정하여보고 이에 대한 타당성을 제시하고자 하였다. 이를 위해 실제 사례지역을 선정하고 실험한 결과 유사가격 권역 별로 군집화가 가능하였고, 현행 유사가격 권역과 많은 차이를 보이지 않아 방법론의 타당성을 제시할 수 있었다.

Recently companies are aggressively Pushing ahead with integrating the systematical applications of internal and external information systems such as Data level, Application level, Process level in the company, Process level between companies. The EAI solution is generally considered as the necessary tool to integrate companies, but the appraisal standard for the EAI solution has not Vet settled in Korea, so the companies have difficulty in deciding whether to adopt the EAI solution or not. Through this report, we first introduce the KRA Project as the best practice in making an application of the settled standard to evaluate and adopt the EAI solution, and then suggest that it can be adapted to companies considering applying to the EAI solution.

Water leakage could be caused deterioration of environmental conditions, user condition, reduction of life span and long term safety in underground concrete structure. Many materials and construction method to repair on these problems have been developed, however, it is not proper to successful repair or raise problem of increasing repair cost However, there are many limitations as practical appraisal methods due to different view of reliability for test methods. Because, it was not enough that the technical objectivity could be lack and also application of environmental condition is inadequate. In this paper, we suggest varied test methods divided to appraisal for property of matter, construction, manufacturing, specification and maintenance, friendly environmental condition. It could be more practical as a objective standard considering various angles. In summery, it should be subdivided and differentiated to accomplish proper application and to select proper materials and construction method for repair even if the synthetical condition is very complicated.

It means that we misunderstood about purpose of greening and using it. So, chosen materials and construction method was not proper for greening, it caused water leakage and decrease performance of concrete structure. Therefore, we would suggest 5 items of test methods considering environmental condition for green roof. Watertightness by water of greening part, root penetration resistance test by root penetration, bacteria resistance by must or bacteria in soil, chemical resistance by rain and chemical agent of fertilizer, and load resistance by soil depth, size of plant. These suggested test methods could be referred as guideline to test in green roof system because of not exist any performance appraisal guideline or standard. Consequently, it should be analysis as technical and institutional subdividing test methods and it need to study constantly as varied angles.

분산 컴퓨터 시스템에서 정보 화일을 효율적으로 관리, 운용하기 위한 화일 할당 문제의 최적해를 구하는 화일 할당 알고리듬을 제안한다. 컴퓨터 노드(site)가 많은 경우 화일 할당에 많은 시간이 소요되므로 선 할당(preassignment)을 수행하여 문제의 규모를 축소하고 계산시간을 개선한다. 할당이 진행중인 상태의 표시치(representative value)를 정확하게 나타내기 위해 기대값을 이용한 평가치 계산기법을 제안하고 빠른 시간에 최적 할당이 이루어지도록 후보 노드(candidate node)에 대한 선택기준(selection criteria)을 설정한다. 선택기준에 의해 각 노드의 화일 할당 여부를 결정하고 최종 평가치가 할당 상태의 전체 비용을 나타낸다. 제안한 알고리듬은 다항식 시간(polynomial time)알고리듬이며 여러 예제에 실현한 결과 할당 소요시간이 개선되고 기존의 할당 알고리듬과 비교하여 최적해를 구하는데 있어 우수함을 나타냈다.

There is a general challenge offered to the field of engineering economics by the introduction of advanced technologies. A survey of the existing literature on evaluation of advanced information and manufacturing system indicate that the traditional approaches are inadequate for economic evaluation techniques used in its appraisal, difficulty in evaluating the potential benefits and criteria used to assess management performance. In this paper, an attempt has been made to overcome the above deficiencies by presenting an approach to account for the justification and selection of the Local Area Network(LAN) architectures. This is based on the Analytic Hierarchy Process(AHP) and is capable of taking into account many intangible factors as well. The usefulness of the proposed approach is demonstrated through a case situation and sensitivity analysis. Finally, some research directions for future work are identified.

This paper proposes a model to assess the maturity level of Six Sigma activities. We classify the maturity level into 5 stages: initial, forming, storming, performing and mature stage. To evaluate the maturity level, 10 categories of Six Sigma with 3 factors each are identified: management leadership, belt system, expert training, establishing execution system, compensation, organization, corporate culture, customer focus, project selection, and management of project results. Scoring 277 items in total, the value of each factor is evaluated by weighted average of those items. Maturity level is appraised by rating the sum of scores of 10 categories that are obtained by summing up the values of its 3 factors. Values of weights and criteria of rating maturity levels are determined by analyzing 90 companies and Six Sigma exper's opinion. This study also shows the actual appraisal results of some companies.

기록평가의 목적은 점차 기록의 선별에서 일종의 주제기반의 수집으로 옮겨가고 있다. 특히 현재의 디지털 기술과 웹의 양 질적 발달은 물리적 수집이 아닌 의미적 수집, 즉 데이터의 연계를 통한 수집을 가능하게 하는 원동력이 되고 있다. 이러한 환경하에서 유네스코를 필두로 국제적으로 '기록유산'에 대한 개념정립이 이루어지고 있다. 이러한 동향을 반영하고 있는 것이 캐나다의 LAC인데, 최근 토탈아카이브즈 정신을 부흥시키고자 새로운 평가방법이자 수집방법을 개발하고 있다. 이것이 'Whole-of-Society 접근법'이다. 이 접근법의 특징은 크게 세가지이다. 첫 번째, 기록유산을 대상으로 하며, 물리적 수집이 아니라 의미적 수집을 목적으로 한다. 또한 그 대상이 기록유산이기 때문에 반드시 기록유산기관 간의 협력이 전제되어야 한다. 마지막으로 이미 발생한 사건에 대한 기록화뿐만 아니라 동시대적 사건에 대한 기록화도 가능하다는 것이다. 평가방법으로서의 'Whole-of-Society 접근법'은 사회이론에 착안하여 사회 구성요소를 식별하는 방식이다. 수집방법으로서의 'Whole-of-Society 접근법'은 디지털기록을 대상으로 하나, 아날로그기록의 소장주체로 안내하는 방식으로 그 대상이 확장된다. 이때의 디지털기록이란 '디지털화된(Digitized)' 기록유산과 '본래 디지털인(Born-Digital)' 기록유산을 포함한다. 그리고 평가 단계에서 식별한 사회 구성요소를 메타데이터 요소로 매핑한 다음, 링크드오픈 데이터로 구축함으로써 데이터 간의 연계를 통한 의미적 수집을 실현한다. 마지막으로 이 연구에서는 국내 평가체계는 그 목적이 선별에 비교적 국한되어 있어 사회의 기록화를 실현하기 어렵다는 한계를 지적하였다. 이러한 한계를 극복하기 위하여 Whole-of-Society 접근법을 적용하여 가이드라인을 제시한다. 가이드라인은 총 8단계를 거치는데, 1단계부터 4단계는 기록화 대상의 선정과 기술이며 5단계부터 8단계는 디지털 환경에서 의미적 수집을 위한 준비절차라 할 수 있다. 한편 가이드라인의 실행을 위한 선행과제를 점검하며 국가기록원의 역할을 촉구한다.

The organization of business included many a factors that gave rise to the stress. The modem peoples in this organization lived in the flood of the stress. Job stress was an important factors which injured of the employee health, the employee health injured reduce the organizational function. The factors such as personal differences, stressors, personality, cognitive traits etc. should be considered in the study of job stress. The cognitive appraisal is an important factor in the study of job stress and a process of coping strategy. Job stress can be controlled and coped by organizational and personal ability. The coping strategy of job stress is also determined by the personal differences rather than by the intensity of stress symptoms. In copying the stress, to be considered the factors such as interpersonal correlation, organizational climate, career development, job redesign, selection and placement, training. However, these factors should be managed in the scientific, objective, reasonable manner effectively.
