Land Suitability Assessment System(LSAS) that was introduced to prevent unplanned development of the nation is divided by Assessment System I and II. Assessment System II can regulate the land use on the development that was defined in the 'National Land Planning and Use Act'. With it, Property right can be limited in the development of private sector and this lure the investor to fabricate the result of land suitability assessment. Because of it, if we can't prepare the overview standard, we couldn't accomplish our purpose that unplanned development prevention and efficient land use. With the suggestion of overview standard for the each factor used in LSAS and the analysis result of it, we presented ways to efficient support and the fixations of LSAS.

As GIS analysis method began to be introduced in late 1980's, studies of land development applying the GIS also started to be proceeded in various fields. Since 2003, Land Suitability Assesment has been adopted in order to prevent national land from development thoughtless for the environment and to plan appropriate national land management in terms of green development. Land Suitability Assessment System II based on diverse GIS analysis method such as Contour Analysis, Overlay Analysis, Network Analysis was particularly adopted to draft plans of specifying and altering of exclusionary zoning as well as installing and maintaining of urban planning facilities. But there has been a lot of problem, like an inaccurate basic data and assessment indicators, unmatched threshold, and contradicted evaluation result between each evaluating systems. Even though it is suited to an evaluation criteria, grade distribution is applied to start at 20, and development-centered evaluation result is offered. Now, we observed how suitability values and grading were changed, ordering to change grade distribution system from $20{\sim}100$ to $0{\sim}100$. In result, it showed changes of grades in some parcels. And in case of suitability values, 87% of parcels decreased to minimum 1 point, maximum 70 points. It means that changing grade distribution system of assessment system II doesn't have only influence on suitability values and grading but it is also an empirical analysis because of considering both development and maintenance.

임상가들은 노령견에서 비정상적인 간효소의 변화를 무시해서는 않됩니다. 전신적 또는 대사적 질병에 대한 검사, bile acid 평가에서부터 좀더 직접적인 간 검사를 실시하고 간의 평가를 위한 체계적인 접근법이 필수적입니다.

The application of a multiple rock classification method, which is a generalization of a binary rock classification, is studied in this paper. In particular, this paper shows how to incorporate qualitative data through a case study. The method suggested in this paper can be effectively used for a systematic multiple rock classification such as RMR system developed by Bieniawski. It will be very useful for rock classifications. In addition, it is known that the expected cost of errors can be atopted to indicate how well a investigation plan is made.

In this study, for the application of land resource evaluation using GIS map overlay method, I have considered about the process that can draw out right results from the problems involving multiple hierarchical indicators and weights. The assumption of this research is that there are two processes in the application of analytic hierarchy process(AHP) and the different results will appear. The two processes are as follows; (1) calculate directly the comprehensive weights to the indicators and overlay the layers(Method I) and (2) repeat the process of map overlay and standardization(Method II). The two precesses are applied on the study site based on the envirosystem in Bong-Hwa, and then some differences were found in the results and it was suggested that the Method II is more reasonable.

Engine System Development Document management system(ESDD) 2.0 has already been operated for systematic engine systems development of KSLV-II. In addition, ESDD 3.0 is under development to manage the documents of before and after engine tests. In this paper, the concept and direction of ESDD 3.0 will be briefly described.

세계보건기구(WHO)에서는 동남아시아를 중심으로 발생하기 시작했던 급성호흡기감염을 '중증급성호흡지증후군(SARS)'으로 공식 명명하고 전 세계에 경보령을 발동, 각국에서는 경계령을 발동하여 환자 발생감시체제를 가동하였다. 또한 올 겨울 SARS가 다시 유행할 것에 대비해 철저한 대비책을 세워나가야 한다는 전문가의 의견이 제시되기도 하였다. 특히 우리나라는 WHO의 SARS 위험평가 분류에 의거 저위험지역에 해당되나 상반기 사스유행지역인 중국 등과 밀접한 교류가 많은 점을 감안하여 교점지역에 준하여 의료기관 중심 SARS 감시체계를 운영하고 단계별로 감시체계를 전국 병원으로 확대하기로 하였다. 이에 편집실에서는 한동안 전 세계 초미의 관심사였던 SARS에 대해 정리해보는 기회를 갖고자 원고를 청탁하여 특별기고로 다루고자 한다.

산화성 물질은 소방법상 위험물 제1류 및 제6류에 속하여 있는 것으로서, 그 위험성은 산화성 물질 단독으로 또는 가연물과 혼합에 의해서 폭발성 또는 폭발적 연소성을 갖는 물질로서, 이를 위한 위험성 평가는 현재 국내의 소방법으로 규정하고 있는 위험물에 대한 연소 및 반응위험성과 같은 제반 위험성을 판별하는 기준이 없어 이를 위한 체계적인 시험법의 요구가 필요한 것이다. 따라서, 본 연구는 국내 소방법 중 위험물 제1류로 구분되고 있는 산화성고체에 대한 연소위험성을 평가하기 위한 보다 체계적이고 재현성 있는 판별 기준을 제시하여 보고자 하였으며, 이를 통하여 기준 시험법의 정립을 기하기 위한 기술자료로서 활용하여 보고자 하였다.(중략)

This study aims to validate a tool evaluating MOOCs for higher education from the perspective of education service. Based on the results of related researches, a potential model for evaluating MOOCs (4 factors and 8 sub-factors) was made. An evaluation tool consisting of 18 survey items was delivered to 138 college students. After data cleaning, 136 surveys were used for exploratory factor analysis (principal component analysis. varimax rotation) and reliability analysis that confirmed the fitness of the potential model. Four exploratory constructs and seven sub-factors were extracted: Factor I was labeled as 'Systemic Learning Experience,' Factor II, 'Value Experience,' Factor III, 'Co-creation of Value Experience,' and Factor IV, 'High Order Learning Experience.' Reliability estimates using Cronbach's alpha indicated that the evaluation tool had good internal consistency. In conclusion, the evaluation tool for MOOCs in higher education was proven to be valid and reliable.

The greenhouse gas (GHG) emission assessment of kenaf pellet, produced from locally generated kenaf residues in South Korea, has been studied based on the EU RED-II methodology for calculating GHG impact of biomass fuels. Based on the production pathway of kenaf residue pellet and emission coefficients from EU JRC report, the life cycle GHG emission of kenaf residue pellet is assessed as 3.0 gCO₂eq/MJ_pellet and the life cycle GHG emission of electricity generated from kenaf residue pellet is assessed as 11.9 gCO₂eq/MJ when electrical efficiency of final conversion is 25%. The potential GHG emission reduction of electricity produced from kenaf pellet is 90.3% compared to the domestic electricity emission factor 42.8 kgCO₂eq/MWh. Also, the electricity produced from kenaf pellet can reduce at least 59.6% of GHG emission compared to the electricity produced from imported wood pellets.
