It can be important framework data to monitor the change of land-use pattern of river boundary in design and management of river. This study analyzed the change of land-use pattern of Gab- and Yudeung River using time-series aerial images. To do this, we carried out radiation and geometric correction of image, and estimated land-use changes in inland and floodplain. As the analysis of inland, the ratio of residential, commercial, industrial, educational and public area, that is urbanized element, increases, but that of agricultural area shows a decline on the basis of 1990. Also, Minimum Distance Method, which is a kind of supervised classification method, is applied to extract water-body and sand bar layer in floodplain. As the analysis of land-use, the ratio of level-upped riverside land and water-body increases, but that of sand bar decreases. These time-series land use information can be important decision making data to evaluate the urbanization of river boundary, and especially it gives us goodness in river development project such as the composition of ecological habitat.

6차 산업은 농업인 소득감소 및 침체되어가는 농촌지역 경제를 활성화할 대안으로서 주목받고 있다. 6차 산업은 1차 산업에 기반 한 2차 산업의 제조 및 가공, 3차 산업의 유통 및 서비스를 통합 또는 연계하는 것을 의미한다. 박근혜 정부는 농업농촌에서 창조경제를 실현하는 구체적 대안으로 6차 산업을 평가하고 다양한 정책적 대안을 제시하고 있다. 또한 이를 뒷받침 하기 위해 모델개발이나 선진사례 분석등의 연구가 진행되고 있는 실정이다. 그러나 6차산업화를 수행하는 경영체에 대한 경영수준 기술수준 리더역량 등을 종합적으로 평가하는 평가지표 개발에 관한 연구는 미흡한 실정이다. 이러한 점에서 본 연구는 6차산업화를 시행하는 경영체에 대한 경영수준 기술수준 리더역량 평가지표 개발을 위해 AHP기법을 활용하여 종합적으로 평가지표를 개발 하였다. 분석결과 한국이 여러 국가와 FTA가 이루어지면서 값싼 농산물 수입이 증대되면서 6차 산업과 관련된 경영체의 수익이 악화될 가능성이 매우 높은 시점에 무한경쟁에서 살아남기 위한 전략 중 가장 중요한 것은 각 개별 경영체가 독자적으로 사업을 운영하기 보다는 내부 역량 강화와 더불어 타 산업과의 연계성을 강화함으로써 상품 및 서비스 판매를 촉진시키고 이를 통해 경영체의 수익을 향상시켜야 한다는 것이다. 따라서 6차 산업 경영체 모두 각자의 위치에서 소비자 신뢰를 얻기 위한 노력들이 필요할 것이며 더욱이 각 경영체간에 협력체계를 구축할 수 있도록 다양한 방안을 모색해야 할 것이다. 또한 스마트 시대에 고객의 니즈가 빠른 속도로 변함에 따라 상품 및 서비스의 수명주기는 점점 빨라지고 있으며 소비자는 새로운 신상품에 찾는 경향이 점점 높아지고 있다. 따라서 6차 산업 경영체는 고객 및 시장 트랜드 변화를 신속하고 정확하게 예측하여 새로운 상품 및 서비스를 시장에 출시하는 노력이 더욱 필요할 것으로 사료된다.

Climate change has been identified as one with the greatest challenges facing nations, government, business and over future decades. Activities to reduce greenhouse gas emissions by the Kyoto Protocol, the international community has been in progress. Korea also has introduced the Emission trading system to reduce greenhouse emission from the supervision of the government. Greenhouse gases emissions quantity should be internationally recognized. Mutual Recognition Arrangement should be recognized as the same greenhouse gas emission. International recognition of domestic verification body of international mutual recognition is required. Efforts are needed to secure the equivalence between the emission rights through direct cooperation with the relative nation accreditation body. Early entry into the IAF/PAC GHG MLA is essential for demonstrating equivalence between greenhouse gas emissions. Emissions trading will also require connection to the EU ETS, California, USA, and Tokyo, Japan to link Emissions trading. In the case of establishing accreditation standards and accreditation criteria, it will be necessary to distinguish between the domestic Energy Target Management System and the Emission Trading System. Independent greenhouse gases verification bodies should be established to meet the requirements of IAF and PAC. It is necessary to revise the qualification criteria for the verification of the greenhouse gas verification body according to international standards requirements. It is necessary to support the role of accreditation bodies of domestic greenhouse gas verification bodies. It is required to join international organizations of international mutual recognition of international trade and the need for pilot projects to link greenhouse gas emissions. The core link to our emission trading system is called EU-ETS, and we will need to join the IAF/PAC GHG MLA GHG. The International Mutual Recognition Agreement (IAF) is expected to allow international interoperability of GHG emissions verification between EA and the PAC. By signing a PAC GHG MLA, it will need to be prepared to prepare for the pilot project to link the emission trading system.

Because students majoring in construction-related fields must develop a broad repository of knowledge and skills, effective transferal of these is the primary focus of most academic programs. While inculcation of this body of knowledge is certainly critical, actual construction projects are complicated ventures that involve levels of risk and uncertainty, such as resistant neighboring communities, unforeseen weather conditions, escalating material costs, labor shortages and strikes, accidents on jobsites, challenges with emerging forms of technology, etc. Learning how to develop a level of discernment about potential ways to handle such uncertainty often takes years of costly trial-and-error in the proverbial "school of hard knocks." There is therefore a need to proactively expedite the development of a sharpened intuition when making decisions. The AGC Education and Research Foundation case study committee was formed to address this need. Since its inception in 2011, 14 freely downloadable case studies have thus far been jointly developed by an academics and industry practitioners to help educators elicit varied responses from students about potential ways to respond when facing an actual project dilemma. AGC case studies are typically designed to focus on a particular concern and topics have thus far included: ethics, site logistics planning, financial management, prefabrication and modularization, safety, lean practices, preconstruction planning, subcontractor management, collaborative teamwork, sustainable construction, mobile technology, and building information modeling (BIM). This session will include an overview of the history and intent of the AGC case study program, as well as lively interactive demonstrations and discussions on how case studies can be used both by educators within a typical academic setting, as well as by industry practitioners seeking a novel tool for their in-house training programs.

In recent times, multi-centralization and decentralization as well as large Capital area and suburbanization in the spatial structure of capital area. With rapid growth, urbanization and industrialization are unsystematic, and growth inequality between regions caused negative effects such as discordant centralization and decentralization, fluctuating land value, and gap between living conditions. Accordingly, this study analyzed urban spatial indexes by the self-governed body in the capital area such as Seoul, Incheon, and Gyeonggi province for the analysis of the regional inequality phenomenon. We examined the characteristics of temporal and spatial changes in urban spatial structure in the capital area by utilizing the distribution pattern and density of city indexes such as population, employment, etc, and then drew the commonality of those factors through factor analysis. We evaluated the drawn results through the city standard index by each city, conducted factor score analysis, and identified the interaction between each factor and Housing Purchase Price Composite Indices index, housing rent price index(Housing Jeonse Price Composite Indices), land price fluctuation rate, diffusion ratio of house, and financial independence.

Employability is a critical issue in construction education. Employability is more than students obtaining employment upon graduation. The concept is far more ranging, and should encompass enabling students to acquire the knowledge, personal and professional skills and encouraging attitudes that will support their future development and employment. This paper describes two case studies relating to how the true concept of employability can be incorporated into the construction higher education curriculum. Case study 1 was a collaborative venture with contributions from a higher education provider, employers, students and a professional body (Association of Building Engineers). It outlines the whole process from course inception through to graduation and feedback. Thus it presents a valid model for other higher education providers of construction courses to adapt or adopt. Case study 2 outlines how the opportunity of a degree programme revalidation process was utilized to introduce modules which would enhance students' employability on graduation.

Construction workers are engaged in many activities that may expose them to serious hazards, such as falling, unguarded machinery, or being struck by heavy construction equipment. Despite extensive research in building information modeling (BIM) for safety management, current approaches, detecting safety issues after design completion, may limit the opportunities to prevent predictable and potential accidents when decisions of building materials and systems are made. In this respect, this research proposes a proactive approach to detecting safety issues from the early design phase. This research aims to explore accident precursors and integrate them into BIM for tracking safety hazards during the design development process. Accident precursors can be identified from construction incident reports published by OSHA using a text mining technique. Through BIM-integrated accident precursors, construction safety hazards can be identified during the design phase. The results will contribute to supporting a successful transition from the design stage to the construction stage that considers a safe construction workplace. This will advance the body of knowledge about construction safety management by elucidating a hypothesis that safety hazards can be detected during the design phase involving decisions about materials, building elements, and equipment. In addition, the proactive approach will help the Architecture, Engineering and Construction (AEC) industry eliminate occupational safety hazards before near-miss situations appear on construction sites.

Purpose: Recent mechatronics technology is the most appropriate high technology in agricultural applications to save repetitious labor. Method: Cow's body parameters were measured by several traditional measurers. Image processing technology was used to measure automatically their parameters to reduce labor and time. The parameters were measured form a small model cow which is easily measured, instead to a real cow. The image processing system designed and built for this project was composed of a PC, grabber card, and two cameras, which are located on the side and the top of the model cow. Tests of verification had measured 10 dairy cows. Result: Nine parameters of the model cow's body were measured, and the difference between the real data and the data by image processing was less than 16.7%. Based on the results of the research, the parameters of a real cow had measured of chest depth, withers height, Pelvic arch height, body length, slope body length, chest width, hip width, thurl width, and pin bone width were compared with image processing data. Conclusions: In the Demonstration test, Result had obtained similar data of cow model experiments, and the most of errors were shown less than 5% relatively good result.

The objective of this paper was to establish the attributes that determines neighbourhood satisfaction in South Africa lowincome housing subsidy scheme ultilising the Delphi approach. This is because the perception and housing satisfaction of lowincome housing beneficiaries toward their housing condition can be studied by examining their satisfaction toward s the neighbourhood factors. The Delphi method was used where the views of housing experts were solicited on 26 potential attributes as identified from li terature. Consensus was achieved after three iterative rounds. The expert"s scored each attributes on a 10-point ordinal scale of impact significance, where 1-2=No impact and 9-10= very high impact. The scales adapted for consensus were: strong consensus, median 9-10, inter quartile deviation (IQD) ≤1; good consensus, median 7 ≤ 6.99and IQD≥2.1≤3. The key findings indicate that there was a good to strong consensus of 19 attributes which were key attributes that the experts perceived as determinants of neighbourhood satisfaction; while 6 other attributes had weak consensus, as they were considered to have a le sser impact in determining residents" neighbourhood satisfaction. However, attributes with weak consensus were the attributes that are highly regarded as core neighbourhood factors in other housing settings. The study contributes to the body of knowledge on th e subject where no consensus has been reached pertaining to indicators for measuring neighbourhood satisfaction in subsidised low-income housing in South Africa.

1997년 교토의정서 체결과 같은 국제적 차원의 환경관련 규제와 관심이 고조됨에 따라, 많은 연구들이 효과적으로 친환경성을 평가할 수 있는 도구나 기술의 필요성을 강조해왔다. 본 연구는 건설 프로젝트의 친환경성을 평가하는 도구의 일환으로 건설현장의 폐기물 관리 성과 평가 툴을 구축하고자 한다. 이 평가 툴의 목적은 폐기물 저감 및 재활용 확대 측면에서 건설현장의 폐기물 관리 성과가 어느 정도 수준인지 정량적으로 평가하는 것이다. 본 연구에서는 평가 툴을 구축하기 위한 기반으로서, 선행연구에서 파악된 폐기물 관리 성과 요인의 성과 수준을 정량적으로 산정하기 위해 전문가 면담 및 설문을 통해 각 요인별 관리 행위 수준과 이들의 중요도를 파악하였다. 또한, 선행연구에서 제시한 평가 툴 구축 개념을 기반으로 실질적으로 전산화된 평가 툴을 개발하여 개별 건설현장 차원에서의 평가가 용이하도록 했다. 특히, 평가의 결과로서 제시되는 최종지표(TI) 및 지표등급(IR)은 건설현장의 폐기물 관리 수준을 정량적으로 비교 평가할 수 있는 기준이 될 수 있다. 폐기물 관리 성과 평가 툴은 건설현장의 폐기물 관리효과를 증진시키기 원하는 시공자 측면뿐만 아니라, 발주자 측면에서도 일정정도의 폐기물 관리수준을 객관적으로 요구할 수 있으므로 그 활용범위가 넓을 것으로 판단된다. 실제 현장에서의 적용가능성과 신뢰도를 검증하는 등의 세부적인 연구가 뒤따른다면 보다 효과적인 건설폐기물 관리방안이 될 수 있을 것이다.
