  • In this paper a new multi-step damage detection approach is provided. In the first step, condensed modal residual vector based indicator (CMRVBI) has been proposed to locate the suspected damaged elements of structures that have rotational degrees of freedom (DOFs). The CMRVBI is a new indicator that uses only translational DOFs of the structures to localize damaged elements. In the next step, salp swarm algorithm is applied to quantify damage severity of the suspected damaged elements. In order to assess the performance of the proposed approach, a numerical example including a three-layer square laminated composite plate is studied. The numerical results demonstrated that the proposed CMRVBI is effective for locating damage, regardless of the effect of noise. The efficiency of proposed approach is also compared during both steps. The results demonstrate that in noisy condition, the damage identification approach is capable for the studied structure.

  • Agricultural environmental indicators (AEIs) are useful tool for evaluating environmental performance induced by agri-environmental policy measures. General and specific criteria have been set to assess the linkages between policy measures and environmental states. In addition, a number of specific AEIs such as nutrient balance indicators and farm management indicators have been posit to review environmental performance associated with agri-environmental policy measures. The proposed environmental subjects encompass soil quality, qualities of underground and surface water, water resource preservation, species and genetic diversity, diversity for wildlife habitats, and agricultural landscapes. The developed AEIs may contribute to establishment or adjustment of environmental targets and ex-ante or ex-post evaluation for environmental performance associated with policy measures. In addition, the AEIs may be useful to consider introduction of new agri-environmental measures and enhance policy efficiency by assessing environmental performance, considering specific locality, and harmonizing support measures.

  • The purpose of this study is to analyze the efficiency of research institutes of futures companies, and to promote the development of futures market and real economy. This study employs DEA-solver software to conduct super-efficiency data envelopment analysis (SE-DEA), and also selects 40 representative futures research institutes in China as decision-making units (DMUs). For data of input and output indicators, we collect from the China Futures Association, Futures Daily, Hexun.com and Webstock.com respectively, and the time duration is the 103 trading days between from October 2019 to February 2020. Then the indicator for the strategy accuracy rate is calculated separately by analyzing the strategies published by each DMUs in public media. In conclusions, most institutes have excessive investment in human resources, and also have insufficient strategy accuracy rate and insufficient published research reports. The findings of this study suggest that Chinese futures companies need to improve the efficiency of research institutes, and better meet the demand of the financial market. In fact, the analysis of the efficiency of the futures company research institute has not been found in the literature worldwide, Application of DEA model in efficiency analysis of securities and futures research institutions and establishment of indicators are the innovations of this paper.

  • The main purpose of this research is to measure and analyze how productive the health centers are and how much inputs(or outputs) in the inefficient health centers should be decreased(or increased) for efficiency. The evaluation of the performance of health centers gives a strong incentive to improve resource allocation in regional health planning. It has been, however, implemented very rarely until now. In this regard, this paper measures the performance of the health centers with a single indicator for multiple-outputs in terms of productivity(technical efficiency), based on Data Envelopment method. The 20 Kyungnam health centers which provide clinic services and specific primary health care services were analyzed. The results show that 50.0% of 20 health centers were productive with respective to overall technical efficiency, 65.0% were productive for pure technical efficiency, and 50.0% for scale efficiency. The inefficient group includes Geoje, Mahsan, Miryang, Sahchun, Tongyoung, Gosung, Nahmhae, Euryang, Hahmahn, Hahbchun health centers. The worst case was identified as Tongyoung health center which represented a 47.5% efficiency, compared with productive health centers. The empirical results for input-output analysis indicates that the low-productive health centers have excessive manpower in administration department, producing low outputs in clinical services and vaccination program. These findings imply that a systemic evaluation of the performance of the Korean health centers and the subsequent structural reform are strongly required.

  • 본 연구는 하천환경평가체계 구축의 일환으로서 식생 평가 지표 및 평가 기준의 검증을 목적으로 수행하였다. 본 연구를 위해 5개 시험하천을 대상으로 68개의 평가단위에서 총 204개의 식생 표본조사구를 설정하였으며, 표본조사구별 상관-종조성 수준에서 식생군집의 분류 및 현존식생도를 작성하였다. 현존식생도를 기준으로 식생자료의 분석을 통해 표본조사의 적정 규모, 식생 지수의 점수 기준, 식생 군집분류의 표준화, 그리고 식생평가지표의 등급화를 위한 종합 점수기준을 검토하였다. 하천 식생 평가를 위해 개발된 식생 다양도 지수와 식생 복잡도, 그리고 식생자연도 지수로 이루어진 식생평가지표의 종합점수 산정 및 등급화는 타당한 것으로 판단되었다. 식생평가지표의 등급화에 대한 식생지수의 기여도를 분석한 결과 식생자연도 지수가 다른 지수에 비해 보다 큰 역할을 하는 것으로 판단되었으나 세부 식생지수 사이의 상호보완적인 관계가 성립되어 있음을 확인할 수 있었다. 또한, 선행 연구에서의 기준의 재검토 및 식생군집 분류의 표준화 작업 등을 통해 개정된 기준을 적용한 결과 식생평가등급 간 변별력이 크게 확보되었음을 확인 할 수 있었으나, 하천구간의 유형에 따른 식생 지수 및 식생평가지표의 등급화는 큰 차이가 없는 것으로 나타났다.

  • 본 연구의 목표는 전문가 조사를 통해 교통부문 녹색성장을 구성하는 부문들의 상대적 중요성을 밝히고 각 부문별 평가 지표를 개발하는 것이다. 이를 위해 먼저 지속가능한 개발이나 생태효율성이라는 기존의 개발 개념과 녹색성장이 어떠한 공통점을 가지며, 녹색성장 고유의 속성은 무엇인지를 설명하였다. 그리고 기존의 연구들을 토대로 교통부문에서 그간 이용되어온 지표들을 선정하였다. 본 연구의 목표인 올바른 지표설계를 위해 평가지표의 구조를 전체목표, 개별목표, 상세 목표로 위계화하여 제시하였으며, 균형있는 지표 설정을 위해 부정적 지표와 긍정적 지표의 개념도 제시하였다. 각 개별목표와 상세목표의 전체목표에 대한 상대적 기여도의 결정을 위해 교통부문 전문가들을 대상으로 설문조사를 실시하고 설문조사 결과를 토대로 AHP 분석을 통해 각 목표들의 가중치를 계산하였다. 분석결과 저탄소 친환경성이 가장 높은 가중치를 갖는 것으로 나타났으며, 경제활동성이 전체 목표달성에서 가장 낮은 비중을 차지하였다. 이를 통해 현재 교통전문가들이 녹색성장 중 성장 부문에 대한 인식이 부족하며, 녹색성장이라는 새로운 개념과 과거의 지속가능한 개발이나 생태효율성을 명확히 구분하지 못한다는 사실을 확인하였다.
