Roundabout has circular traffic island in the intersection center and is kind of intersection where the automobile bypass circular traffic island. In Korea, the provisional Roundabouts Design Guidelines were published in 2004 by MLTM (Ministry of Land, Transport and Maritime Affairs). This guideline did not discussed domestic traffic circumstance. It just only introduced foreign instances and their guidelines. In addition, the recent National Competitiveness roundabouts as part of the green growth has been concentrated on the interest. In this paper, 90 degree of the 4-legged roundabout was compared with 72 degree, 45 degree, and 30 degree 5-legged roundabouts by micro simulation VISSIM.

In this paper, we present a simulation model of Slammer worm propagation process which caused serious disruptions on Internet in the you of 2003 and analyze the process of Slammer by using NS-2. Recently introduced NS-2 modeling called "Detailed Network-Abstract Network Model" had enabled packet level analysis. However, it had deficiency of accommodating only small sized network. By extending the NS-2 DN-AN model to AN-AN model (Abstract Network-Abstract Network model), it is effectively simulated that the whole process from the initial infection to the total network congestion on hourly basis not only for the Korean network but also for the rest of the world networks. Furthermore, the progress of the propagation from Korean network to the other country was also simulated through the AN-AN model. 8,848 hosts in Korean network were infected in 290 second and 66,152 overseas hosts were infected in 308 second. Moreover, the scanning traffics of the worm at the Korean international gateway saturated the total bandwidth in 154 seconds for the inbound traffic and in 135 seconds for the outbound one.

최근 국내에서는 하천변 생태계를 대상으로 생태구조 및 서식처 평가 등 많은 연구가 진행되었음에도 불구하고 생태적 변화를 예측하고 예측된 결과에 따라 생태복원 대책을 수립할 수 있는 연구는 현재까지 미흡하다고 볼 수 있으며, 이는 생태복원 연구에 있어 주요과제라고 할 수 있다. 이에 반해 유럽과 미국에서는 수문학적 서식처 조건에 따른 식생 반응 예측 등 수문생태 모형에 대한 연구가 꾸준히 이루어져 왔으며, 최근에는 습지, 홍수터 등을 대상으로 생태보전 복원분야에 널리 응용되고 있다. 본 연구에서는 국외의 수문생태모형 적용사례를 분석하여 국내 적용가능성 및 문제점에 대한 타당성을 제시하고자 하였다. 그 대상으로는 유역 내에 홍수량 분담을 위한 천변저류지를 적용하였으며, 의미상으로 홍수터(범람원), 습지 역시 해당 범위에 포함할 수 있다. 천변저류지는 홍수기와 비홍수기에 따라 활용 측면을 구분할 수 있으며, 이런 맥락에서 천변저류지의 수위변화는 식생 변화의 중요한 요소(factor)가 될 수 있다. 그 외 범람시기, 범람일수, 건조기간 등을 포함한 수문요소 역시 수문생태 모델의 예측 변수인 식생 성장에 영향을 미치게 된다. 이러한 수문/생태시스템의 상호관계를 활용하고 모형의 형태를 국내 식생에 대한 생리학적 특성에 맞게 변화시킬 수 있다면 국내 천변저류지에도 충분히 적용 가능할 것으로 판단된다. 또한 잠재적으로 식생 성장에 영향을 줄 수 있는 다양한 환경조건 예를 들면 영양물질, 토양구조, 토사 퇴적 등을 적용대상지 환경에 맞게 포함하거나 고려할 수 있다면 모형의 재현성을 더욱 높일 수 있을 것이다.의 기대효과를 가져올 수 있으리라 생각되며 분석된 인자들은 수달 서식지를 위한 하천정비의 기초자료에 유용할 것으로 보인다.따른 유량측정망을 구축하는 것이다.의 의사결정 지원 도구가 될 것이다. 따라서, 본 연구에서는 도시유역의 물순환 해석을 위한 일련의 과정, 즉 자료의 조사 및 취득에서부터 물순환 해석 모형을 이용한 정량적 현황파악, 물순환 개선 기법 및 평가를 수행함에 있어 주요 착안점 및 실무에서의 기술적 가이드를 제공하고자 하였으며, 보다 세밀한 도시유역의 물순환 해석을 위하여 우리나라와 일본에서 적용이 활발한 물리적 기반의 분포형 모형(WEP, SHER, SWMM)의 적용사례를 통하여 국내 도시하천의 물순환 해석에 활용함에 있어서의 실질적인 적용절차 등을 제시하고자 하였다. 한다.호강유역의 급격한 수질개선을 알 수 있다.世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와 동년대에 동일한 목적으로 찬술되었음을 알 수 있다. $\ulcorner$경상도실록지리지$\lrcorner$(慶尙道實錄地理志)에는 $\ulcorner$세종실록$\lrcorner$(世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와의 비교를 해보면 상 중 하품의 통합 9개소가 삭제되어 있고, $\ulcorner$동국여지승람$\lrcorner$(東國與地勝覽) 에서는 자기소와 도기소의 위치가 완전히 삭제되어 있다.

Forest healing is a natural method that utilizes various natural environmental factors of forests to enhance immunity and to heal mental and physical pathologies. The aim of this study is to suggest implications for the future development of forest healing by analyzing the characteristics of facilities and programs in 28 national and public healing forests in Korea. The concept of forest healing and programs is defined, and healing forests operating in Korea are classified by size. The facility operation and program characteristics of healing forests were analyzed according to size, and the results were used to suggest a future direction for the development of domestic forest healing. The research results are as follows. First, domestic healing forests have gradually been reduced in size since they were first opened in 2009, which is the cause of the competitive creation of local governments. Second, healing spaces, forest paths, and programs for the elderly, pregnant women and disabled should be expanded. Third, lodging programs need to be expanded, and subsidies for usage fees from local governments are required. Institutional supplementation should be provided to link program development and facilities and to clarify procedures and standards for forest healing facilities.

This study attempts to analyze the trade costs of domestic firms utilizing the FTAs in terms of burden of expenses in managing the rules of origin. In doing so, we classify the managing costs of FTA rules of origin into three categories (that is, (i) ex ante costs from acquiring necessary information and building the infrastructure in the advance stage before the FTAs, (ii) the actual costs of the origin management in the application stage of FTA preferential treatment, (iii) ex post management cost in the preparation stage of origin verification) and perform a survey on the greater details on each category. Using the comprehensive results from the survey regarding domestic firm's use of FTAs, this paper also discusses the issues related to small and medium-sized firms and addresses the concerns involved with their managing costs of FTA rules of origin. Importantly, this paper emphasizes the importance of government supports to reduce inefficiency induced by the additional costs that domestic firms face in their use of FTAs and proposes the various policy implications regarding the managing costs of rules of origin.
