The effectiveness of Building Information Modeling (BIM) tools and processes has been recognized by the industry and owners are beginning to adopt Triple Bottom Line accounting practices, to enhance economic performance and environmental and social performance. However, the widespread and practical application of Green BIM remains largely unrealized. The authors identify that lack of understanding of the applicability of sustainability metrics to BIM design process is a significant barrier to this adoption. Through literature review this paper outlines the various sustainability metrics available to construction and elaborates on the potential of BIM for sustainable design. The paper maps and correlates applicable concepts of sustainability evaluation systems to BIM and describes the constraints in current BIM tools.

This work firstly aims to analyse the balance between tangibles and intangibles as well as among human capital, structural capital and relational capital of evaluation indicators for the research institutes in science and technology sector conducted in 2006, by adopting intellectual capital model. The research question of this work comes from that while the R&D activity can produce both tangibles and intangibles, there have no been methodologies to relevantly measure and rationally judge these, in particular, intangible performance. The result shows that the institute evaluation system in 2006 had given more weight on tangibles and structural capital than intangibles and other intellectual capitals such as human capital and relational capital, in comparison to the past evaluation system, even though, in principle, the current evaluation system has to deal with the intangible research performances as well as tangible ones in economic, social and cultural perspective. Finally, based on these analysis, I will try to suggest some policy directions for overcoming the deficits of indicators in institute evaluation system.

In order to successfully adapt in ever-changing social and economic environment, organizational members need to get a capacity to be open to accepting change, effectively leverage the knowledge assets accumulated inside and outside the company for pursuing new values. In this study, we defined such competence as generativity capacity and demonstrated mechanism for forming generativity capacity and an impact on job performance. We suggested absorptive capacity, tertius iungens orientation, use of information technology as antecedent variables of generativity capacity. For empirically verifying the proposed model, we collected sample data from 201 workers and conducted analysis using a structural equation modeling. The empirical analysis results revealed that all of the proposed antecedent variables significantly impacted on generativity capacity, which in turn had a significant effect on job performance. We expect that this study will provide researchers and managers who want to get a broader perspective on knowledge management beyond the boundaries with useful theoretical and practical implications.

Roadbed failure due to the rainfall may bring out social and economic demage such as the loss of life and property, the consumption of time and cost for recovery, and the delay of logistics in railway. In this study, the method using Geotextile Container was applied to rehabilitation of the railway roadbed which was failed by rainfall. The real scale tests with the simulated train loading were performed in order to evaluate the dynamic performance at the railway roadbed using Geotextile Container. The results of these tests were compared with unreinforced and reinforced cases with Geotextile Container, respectively. The data gathered by various measurement devices from these real scale tests would be useful to evaluate and understand the roadbed with Geotextile Container. Furthermore, the results of this study would be useful to ensure the workability and to save much time for restoration and to be widely applied to practical use.

In recent years, the number of female workers pursuing careers in the construction engineering and management field has increased, despite the fact that the job positions have been traditionally considered as retaining job functions and/or qualities that are more appropriate to male than female. This may be attributed to the fact that the positions also require delicate and/or detail-oriented job functions, which can be successfully performed by female. It is important for project participants to understand the working conditions for female field managers by analyzing their job performance. This study collects expert opinions regarding female's managerial performance on job site. Survey questionnaires were administered to two focus groups, male and female field managers who work for general contractors. This study contributes to encouraging female's social and economic involvement by investigating the challenges they face in the workplace, and provides measures to respond to such challenges.

본 연구는 지방대학 특성화 사업의 중요도와 실행도를 분석하여 사업의 목표 실현과 사업이 나아갈 방향을 제시하고자 한다. 연구대상은 사회적경제 과목을 수강한 학생들을 대상으로 자기기입식 설문조사를 실시하였고, 연구방법은 IPA를 활용하여 중요도와 실행도를 분석하였다. 연구 결과, 지역대학 특성화사업 목표를 달성하기 위해 사회적경제 특성화 기반을 우선적으로 마련해야 하고, 그 바탕 위에 창의적인 인재양성과 더불어 산 학 연계의 교육과정 구축이 필요하며 지방대학 특성화 사업을 위해 대학의 체질을 개선하고, 학부교육을 내실화하여 창조경제 견인하기 위해 이들에 대한 중요도 제고와 실행도를 높일 필요가 있는 것으로 나타났다. 한편, 성별 구분에 있어서는 남학생이 여학생보다 중요도와 인식도가 높고, 학과별 구분에 있어서는 경제학과가 영어과와 회계정보학과보다 높은 것으로 나타났으며 고학년 일수록 중요도와 인식도가 높은 것으로 나타나 인식차이를 극복하기 위해 사회적경제에 기본적 지식 교육과 단계별 교육과정을 개발하여 교육할 필요가 있는것으로 나타났다. 본 연구의 시사점은 지방대학 특성화사업 목표를 달성하기 위한 평가 결과, 사회적경제 수강생들이 체감할 수 있는 영역에 대해 중요도와 실행도를 높게 인식하고 있으나 교육부와 사업단에서 달성하고자 하는 사업의 분야에는 중요도와 실행도를 낮게 인식하고 있어 교육부와 사업단이 목표하는 지방대학 특성화를 위해 대학체질 개선, 학부교육 내실화, 창조경제 견인 등에 노력을 기울여야 한다.

이 논문의 목적은 1990년대 발생한 광우병 위기 이후 유럽연합이 식품안전을 강화하기 위해 도입한 정책을 사회후생 및 정치경제적 관점에서 평가하는 것이다. 2002년 일반식품법 도입 이후 입법화된 식품안전과 관련된 공동체 법규들의 주요 특징은 모든 회원국이 반드시 지켜야하는 동시에 식품산업 전반에 적용되는 수평적 규제라는 것이다. 역선택 문제를 해결하거나 식품소비 시 발생하는 부정적 외부효과를 줄이기 위한 식품안전규제는 관련 식품 분야의 구체적인 수요 및 비용 조건에 따라 미세 조정되어야한다는 이론적 연구들에 비추어 볼 때 2002년 이후 강화된 식품안전관련 공동체 법규는 사회후생의 관점에서 과규제된 것이다. 본 연구에서는 정치경제적 관점을 택하여 유럽연합 회원국 정부들뿐만 아니라 식품가공 및 유통업자, 소비자, 농축산업자 등 다양한 이해집단이 공동체 식품안전 규제들을 수용하게 된 배경을 설명하고, 이 규제들이 비회원국, 특히 개발도상국 생산자들에게 보호주의적이었다는 것을 보여준다. 유럽연합의 설립목적이 기본적으로 단일시장을 형성하여 공동의 경제적 이득을 추구하는 것이라면 지나치게 제한적인 식품안전규제의 부정적 영향을 줄이기 위한 정책적 조치가 필요하다.

Purpose Youth unemployment is a social problem that continues to emerge in Korea. In this study, we create a model that predicts the employment of college graduates using decision tree, random forest and artificial neural network among machine learning techniques and compare the performance between each model through prediction results. Design/methodology/approach In this study, the data processing was performed, including the acquisition of the college graduates' vocational path survey data first, then the selection of independent variables and setting up dependent variables. We use R to create decision tree, random forest, and artificial neural network models and predicted whether college graduates were employed through each model. And at the end, the performance of each model was compared and evaluated. Findings The results showed that the random forest model had the highest performance, and the artificial neural network model had a narrow difference in performance than the decision tree model. In the decision-making tree model, key nodes were selected as to whether they receive economic support from their families, major affiliates, the route of obtaining information for jobs at universities, the importance of working income when choosing jobs and the location of graduation universities. Identifying the importance of variables in the random forest model, whether they receive economic support from their families as important variables, majors, the route to obtaining job information, the degree of irritating feelings for a month, and the location of the graduating university were selected.

Noise problem that occurs on the road is raising a lot of problems in the economic, social and environmental aspects. The active noise control (ANC) systems based on the filtered-X least mean square(FxLMS) algorithm have a problem with compensating the acoustic feedback of secondary route. However, newly proposed correlation-LMS(CLMS) and expanded CLMS algorithms have slightly much calculation and are minutely behind performance, these have a advantage not in measuring transfer function onerously so that we can easily adapt these in real time. The CLMS and expanded CLMS algorithm was developed to improve the real-time implementation performance under the variable input noise such as road noise environment. In this paper, we compared and analyzed their performance. From the results of the Matlab simulation for an ANC system, it is shown that expanded CLMS algorithms are more convergence speed and keep the desirable performance even in the input of road noise situation.
