Main airports in the Intra-Asian market have faced competition not only to attract China-bound transshipment cargoes but also to be hub airport in same region. In spite of such a importance, the previous research has been short of evaluation of airport competitiveness. Implication of the previous research has mainly been focused on evaluation of airport critical factor service qualify and efficiency. The aim of this paper is to present critical points that affect airport competitiveness using an algorithm based on reversed fuzzy evaluation and senario method. The results of senario analysis and reversed fuzzy evaluation shows that Incheon international airport needs to enhance service level of 7% as a result of senario analysis and service level of 5% and brand equity level of 10% at the same time as a result of reversed fuzzy evaluation analysis, to ensure competitiveness in same region.

In this study, we predict the generation of end-of-life photovoltaic modules when Feed in Tariff applied, in Republic of Korea. Based on the installation of photovoltaic modules, we prepared three different senarios in order to estimate the generation of end-of-life photovoltaic modules. The senarios are i) early worn-out, ii) mid worn-out and iii) late-worn out senario. We selected the mid worn-out senario to estimated the amount of end-of-life photovoltaic modules in this study. Establishment of the end-of-life module generation scenario predicted generation of end-of-life photovoltaic module, and forecasted generation amount of end-of-life module to which Feed in Tariff was applied in consideration of installed photovoltaic modules installed by Feed in Tariff support. The generation of Feed in Tariff-applied end-of-life modules increased from 2021 to 2025 compared to without Feed in Tariff, and since then, the Feed in Tariff-applied end-of-life modules were generated as waste modules during the relevant period (2021 ~ 2025).

Domestic trucking transportation market does not have only the poor business environment but also the serious defects on the transportation trading structure. It makes weaken the competitiveness of trucking industry and hinders the development of trucking industry. The problems of trucking industry such as the recession of the Korean economy and decrease of the trucking charge cause the truck drivers suffer. Korean government and national assembly try to change the law of truck transportation business. The suggested law includes the obligation of trucking information networking system and it can make the transportation business structures more efficiently. This article deals with the strategies for the establishment of trucking transportation networking system and examines the cost-benefit analysis assuming the four demand senario. The results suggest the establishment of the information system not based on the individual trucking industry but on the joint industry at the level of the local area. This article also suggests that the information system has a positive financial feasibility.

In both inside and outside of our country, the interest of the new generation S/W architecture, the SOA(Service Oriented Architecture) is whooped up. We expect that the SOA will become general S/W architecture in several years, but the most compaines of S/W Industry still think that the SOA have much risk to adapt as their s/w architecture. In this paper, We performed the senario based verification of the SOA quantitatively and qualitatively, and presented the validity of the S/W architecture view and the method of adoption of the SOA.

This paper illustrates the case studies of reliability evaluation for interconnecting power systems in the north east Asia by using the tie line constrained equivalent assisting generator model(TEAG), which has been already developed in the second project year. A reliability evaluation program, it is named, NEAREL. based on the TEAS model was made. The reliability evaluation results for the seven interconnection scenarios of the actual power systems of six countries in the north east Asia are introduced and compared. The reasonable capacity of the tie line for three countries interconnection senario is suggested from sensitivity analysis.

In order for efficient Bluetooth Baseband functional test, Bluetooth SIG (Special Interest Group) provides with Test Suite Structure (TSS) in the Bluetooth specification version 1.1. Bluetooth Baseband hardware which needs to be authenticated should implement the test specification defined in the TSS part I.1 through I.3. In this paper, we discuss the method to verify and test a Bluetooth Baseband implementation based on the TSS version 1.0. Also, we describe various senario and implementation possibilities to perform the Bluetooth Baseband authentication test.

안전한 생화환경에 대한 국민수요 급증 및 사회변화에 따른 장기적 관점의 재난관리체계가 필요하고 우리나라의 경제성장이 거듭됨에 따라 고도화된 기술문명 사회로 급속히 발전한 결과 과거와는 달리 지하철 사고, 가스폭발사고, 화학물질 분출사고 등 사회재난의 유형이 다양화되고 있을 뿐만 아니라 그 피해의 양상이 복잡화 되고 있어 이에 대한 전략적인 대응이 필요하다. 따라서 본 연구에서는 사회재난 사고유형 및 대응사례 분석을 통한 재난대응 시나리오를 개발하고, 관련 법제도 검토를 통해 법개정 방안을 수립하여 시범사업 기반 구축의 방향을 제시하고자 한다.

In spite of numerous advantages in railroads such as mass transportation, high reliability, and environmental soundness etc., the value of railroad construction is relatively underestimated compared to road. This is because the current method of evaluation focuses mainly on economic effect. In this study, considering recent research results, the environmental value of railroad construction was assessed by calculating the effect of reduction of emissions and water contamination. With these two benefits, the environmental effect produced by railroads and road construction was calculated and compared to each other using EMME/3. As a result, the senario 4 which considers 'Hot/Cold start' condition and water contamination had highest benefits. Furthermore, the environmental effect produced by railroad is 55~101% higher than road construction. If the suggested method is used in the current appraisal system, the environment-friendly mode like railway would be highly valued, much more than before.

Changes in biota, species distribution range shift and catastrophic climate influence due to recent global warming have been observed during the last century. Since global warming affects various sectors, such as agriculture and vegetation, it is important to predict more accurate impact of future climate change. The purpose of this study is to examine the observed distribution of Abeliophyllum distichum in the Korean peninsula. For this purpose, two period (present and future) climate data were used. Mean data between 1950 and 2000, were used as the present value and the year 2050 and 2080 data from A1B senario in IPCC SRES were used for the future value. Potential habitation is analyzed by MaxEnt(Maximum Entropy model), and Abeliophyllum distichum's coordinates data were used as a dependent variable and independent variables are composed of environmental data such as BioClim, altitude, aspect and slope. The result of six types GCM mean calculation, the potential habitability decreased by 40-60% of the average existing distribution. The methodogies and results of this research can be applicable to the climate changing adaptation stratiegies for the biodiversity conservation.
