As the number of web users is increasing, the leakage of personal information is increasing. If some personal information is leaked, the victim can suffer from material damage or mental damage at the same time. Most of the leakages are result from the people who works for the personal information by accident or design. Hence, the Ministry of Public Administration and Security proposeed the measuring index and enumerates the details. The index is used in a system to check protection of a personal information. However, because this system is used to evaluate after the leakage, it cannot be used to construct some security system or programming a security system. To solve this problem, it needs to express the diversity of items and be able to count what assessors want to count. Thus, a summary sheet which displays the result of the tool will be presented in a radial form graph. Details will be presented as a bar graph. Therefore, it will be proposed that the tool can grasp the weak point and propose the direction of security.

Although waste management in construction industry has a significant impact on both economical and environmental issues, the current level of waste management performance in Korean construction is reported as relatively low. To improve any type of management performance, it is necessary to diagnose the current status of the performance level. In this context, this research is aimed to identify important factors in influencing the waste management performance and to develop an evaluation tool for the purpose of assessing the level of the performance for a particular construction site. In this paper, 59 influential factors have been identified and categorized into five classes, i.e., manpower, material, method, management, and policy, in terms of the characteristics of the factors. In addition, an evaluation tool has been developed in order to effectively quantify all the 59 factors based on a thorough industry survey. The output of the Tool, which is Waste Management Index, effectively assess the level of waste management performance for a particular project and provide with the most leveraged factors in need for improvement in waste management performance.

Inequality of environmental impact is forecast to deepen due to the damage of environmental risk by the interaction between environmental and social inequalities causing more harms to environmentally vulnerable population. This study assessed the integrated cumulative impact of Seoul using Environmental Health Screening Tool developed by Environmental Protection Agency of California. In order to screen vulnerable area to environmental health, 10 indexes have been selected according to the environmental burden of exposure to environment and public health effects, population characteristics of sensitive populations and socio-economic factors. As a result of assessment conducted on cumulative impact of Seoul for years 2009~2011 through Environmental Health Screening Tool, risk factor for districts of Gangseo and Gangnam of Seoul showed high - Gangseo area indicated high risk factor both in environmental burden and population characteristics, while Gangnam area appeared high in environmental burden. The result of survey will be able to suggest scientific basis to push through fair and effective environmental policy in consideration of environment vulnerable population.

The research on the FPGA CAD tools in academia has been lacking practicality due to the underlying FPGA fabric architecture which is too simple and inefficient to be applied for commercial FPGAs. Recently, the database of placement positions and routing graphs on commercial FPGA architectures has been built, and provided for enabling the academic development of placement and routing tools. To extend the limit of academic CAD tools even further, we have developed the evaluation toolkit for the K-FPGA architecture which is under development. By providing interface for exchanging data with a commercial FPGA toolkit at every step of mapping, packing, placement and routing in the tool chain, the toolkit enables individual tools to be developed without waiting for the results of the preceding step, and with no dependency on the quality of the results, and compared in detail with commercial tools at any step. Also, the fabric primitive library is developed by extracting the prototype from a reporting file of a commercial FPGA, restructuring it, and modeling the behavior of basic gates. This library can be used as the benchmarking target, and a reference design for new FPGA architectures. Since the architecture is described in a standard HDL which is familiar with hardware designers, and read in the tools rather than hard coded, the tools are "data-driven", and tolerable with the architectural changes due to the design space exploration. The experiments confirm that the developed library is correct, and the functional correctness of applications implemented on the FPGA fabric can be validated by simulation. The placement and routing tools are under development. The completion of the toolkit will enable the development of practical FPGA architectures which, in return, will synergically animate the research on optimization CAD tools.

In this study, simplified LCA (life cycle assessment) tool was developed to increase accessibility and availability on LCA timber construction. The result of simplified LCA was compared with commercial program on LCA (Simapro.7) to verify its availability. As a result of evaluating environmental impacts with the Life Cycle Inventory of all processes, gap between LCA and simplified LCA tools of timber construction was about 1%. Therefore, the simplified LCA tool could analyse greenhouse gas emissions of timber construction and to expand number of data set through improved conveniency of users for developing database of timber construction in Korea. The reduction effects of greenhouse gas emissions of timber construction was about 53% of total emission offset up to construction phase. The results of this study would support decision making process to expand to timber construction policy to showcase environmental friendliness of timber construction. It was expected to contribute to response to the New climate regime in forestry.

건강영향의 중요성에 대한 인식이 증가함에 따라, 본 연구는 건강영향평가의 최적 도입방안을 연구하는데 목적을 둔다. 한국의 지난 30년 동안 환경영향평가(EIA)를 수행하고 있다. EIA내의 스크리닝, 스코핑, 분석, 영향평가, 협의, 보고서 검토, 의사결정 및 모니터링 과정들은 HIA의 필수적인 부분이 될 것이다. 스크리닝 및 스코핑 과정은 아직 EIA내에 포함되어 있지는 않지만, 기존 EIA 과정내로 HIA를 통합하는 것은 한국에서 매우 효율적인 방안이 될 수 있다. 나아가, EIA내의 기존 공중-위생 항목을 보건 영향을 고려하기 위해 충분한 결정인지를 지닌 환경-보건항목으로 교체 및 확장하는 것이 바람직할 것이다. 한국의 경우, HIA의 초기 시행을 고려할 때 사회과학 및 심리학에 기초한 전향적 및 정량적 접근법이 보다 적합할 것이다. 본 연구에서는, 체크리스트와 툴키트가 개발되었으며, HLA의 적용 및 보급에 있어 매우 유효한 지침이 될 수 있을 것이다.

고랭지 지역 등에서 매년 집중강우로 인하여 많은 양의 토양유실이 발생되고, 이로 인한 탁수 사태가 장기화되면서 많은 환경 및 사회적 문제가 발생되고 있다. 환경부에서는 2007년 고탁수 발생지역을 비점오염원 특별 관리지역으로 지정하고 전 방위적인 비점오염 저감 노력을 수행하고 있다. 최근 환경부와 농림부에서는 농업지역의 비점오염원 저감을 위해 필지단위 BMP를 적용하고, 저감효과를 모니터링하고 있으며, 2011년도에는 BMP 적용에 따른 삭감효과를 평가할 수 있는 모델이 개발되었다. 하지만 모델을 이용하여 정확한 BMP 적용에 따른 삭감효과를 산정하기 위해서는 필지에서 발생되는 유출량 및 유사량에 대한 검보정이 수행되어야한다. 그러나 기 개발된 삭감효과 산정모델은 사용자가 유출량 및 유사량에 대한 검보정을 수동으로 실시하기 때문에 검보정 과정 중 사용자의 주관적인 경향이 모델 변수 선정에 영향을 미칠 수 있어 비효율적이다. 정확성 및 객관성을 확보한 검보정 수행을 위해서는 반드시 자동 검보정 툴 개발이 필요하다. 이에 본 연구에서는 Parasol 방법을 이용하여 삭감효과 산정모델의 자동 검보정 툴을 개발하고 적용성을 평가하였다. Parasol 방법은 최적화 및 불확실성 분석방법으로, 원격 토지 표면 모델링 토양 침식, 지하 수문학과 같은 유역 모델 보정 및 수문학의 다른 분야에서 많이 사용되고 있는 SEC-UA 알고리즘을 사용하여 매개변수들을 자동 변환하고, 목적함수로 SSQ를 이용하여 최적매개변수를 찾아낸다.

Project risk factors are major triggers in cost performance in construction projects. Both owners and contractors are highly concerned in managing their risks in earlier times. As such, it is needed to provide a robust risk evaluation methodology in identifying and assessing the potential risks before project execution. In previous research, risk identification was conducted only in specific phases, i. e., design, procurement, construction. Therefore, the comprehensive approach in risk management was limited and their quantifying method was not well-defined. Since the benefit of planning in earlier times are maximized compared to later times, the risk management should be implemented in earlier planning stage. This study provide a new risk evaluation method by incorporating previous research and extensive literature review. By quantifying each risk factor from an extensive industry survey, the proposed tool can enhance the reliability of each factor weight and also the weights are categorized from a various perspectives, i.e., owners, contractors, lager-scale company, smaller-scale company, building projects. The proposed tool can be also useful in deciding on whether to proceed a particular project and How much the project contingency would be set aside in project execution. The study findings can also expedite the risk management procedure in a more systematic approach.
