The summer algal flora and community of 15 uninhabited islands in Dochodo, southwestern coast of Korea, were investigated from 9 June to 16 September 2007. A total 53 species (10 green, 14 brown and 29 red algae) of marine algae were identified. Among 15 uninhabited islands, the number of species observed was the highest as 33 species at Jeongdo and Gyeongchido the least as 24 species at Hugdo and Mido. The dominant species were Enteromorpha compressa, Ishige okamurae, Gloiopeltis furcata, Ulva pertusa and Sargassum thunbergii. The algal zonation of intertidal zone was figured out by Gloiopeltis furcata, Caulacanthus okamurae ? Ulva pertusa, Sargassum thungergii ? Gelidium amansii, Sargassum horneri from upper to lower zone. The flora investigated could be classified into six functional groups such as coarsely branched form (39.6%), filamentous form (25.8%), sheet form (14.1%), thick leathery form (9.9%), jointed calcarious form (5.6%) and crustose form algae (4.9%).

Numerous disorders and etiologies may underlie increased eosinophil counts. Hypereosinophilia (HE) is defined as a peripheral blood eosinophil count greater than 1,500/mm3 and may be potentially harmful because of tissue damage. Hypereosinophilic syndrome (HES) also represents a heterogeneous disorder characterized by persistent HE with the evidence of organ dysfunction, clinical symptoms, or both caused by eosinophilia. The refining criteria and subclassification of HE and HES are currently being revised on cellular and molecular based diagnostic methods. Initial approaches focus on evaluating various underlying causes, including helminthic infections, adverse drug reactions, allergic diseases, and neoplastic diseases. When secondary causes of HE are excluded, the workup should proceed to the evaluation of primary/clonal bone marrow disease, including fip 1-like 1-platelet driven growth factor receptor alpha (FIP1L1-PDGFRA) mutation. Concurrently, if the patient has symptoms and signs, organ damage or dysfunction must be evaluated. Although, corticosteroids are the mainstay of therapy in confirmed HES, imatinib is considered a definitive treatment for FIP1L1 PDGFRA, platelet driven growth factor receptor beta rearranged HE and HES. In this article, we discuss recent advances in the classification of and practical approaches to HE and HES. In addition, we introduce several promising therapies for HE and HES.

지능형 교통 시스템(Intelligent Transport System; ITS)의 상용화를 위한 작업이 국내외에서 활발하게 이루어지고 있는 시점인 지금 차량 간 통신 (Vehicle-to-Vehicle; V2V) 환경 해석은 관련 법규 제정에 있어서 필수적인 과정이다. 하지만 전기적으로 대형인 도로상 다수의 차량이라는 해석환경으로 인하여 계산 자원 부족으로 일반적인 수치해석 도구를 이용한 환경의 해석이 불가능한 상황에 대하여 본 논문에서는 해석 환경의 적절한 분리와 결과의 후처리로, 적은 계산 자원을 사용하여 환경 해석을 근사할 수 있는 기법을 제안하였다. 제안된 기법은 전자기원(Electromagnetic field source)과 관측 지점 주변, 그리고 그 선상의 산란체들 중 일부만을 포함하는 해석을 수행한 뒤 결과들을 중첩의 원리를 적용한 벡터합을 통하여 결과를 근사하는 방식을 사용하였다. 본 논문에서는 제안한 기법의 적용범위 및 가이드라인, 일반적인 해석 기법과의 정확도 비교를 위한 예시를 제시하였다. The commercialization of ITS(Intelligent Transport System) is in sight including V2V(Vehicle-toVehicle) communication and analysis of related electromagnetic circumstances is essential process in relevant legislation. However analysis including numbers of vehicles have electrically large environment which leads to a lack of computational resources. In this letter, we suggest superposition method which require much less computational resources by subgrouping environment and using post-processing of results. Suggested method approximate original result by superpositioning of analysis which include scatterers near source, observation point. This letter also presented guideline of method and example for comparison with full analysis result.

The summer algal flora and community of 9 islands in Dadohae National Park, southwestern coast of Korea, were investigated from June to September 2008. A total of 81 species (13 green, 22 brown and 46 red algae) of marine algae were identified. Among 9 islands, the number of species observed was the highest as 65 species at Jindo and the least as 37 species at Hongdo. The dominant species were Enteromorpha compressa, Ulva pertusa, Sargassum thunbergii, Gelidium amansii, Caulacanthus okamurae, Gloiopeltis furcata, and Symphyocladia latiuscula. The algal zonation of intertidal zone was figured out by Gloiopeltis furcata, Ishige okamurae, Caulacanthus okamurae-Enteromorpha compressa, Sargassum thungergii-Gelidium amansii, Symphyocladia latiuscula from upper to lower zone. The flora investigated could be classified into six functional groups such as coarsely branched form (38.1%), filamentous form (24.7%), sheet form (11.3%), thick leathery form (13.9%), jointed calcarious form (6.3%) and crustose form algae (5.7%). R/P and (R+C)/P values were 2.2 and 2.8, respectively. A cluster analysis of species occurrence was suggested that the number of marine algal species was different from greatly among the sampling sites.
임의 대형구조 전자기 해석을 위한 CBFM의 빠른 원거리 상호 작용 계산 알고리즘

본 논문에서는 임의의 대형구조의 전자기 특성을 효율적으로 해석하기 위해 대표적인 전자기 수치해석 기법의 하나인 모멘트법 기반 직접풀이법 중 CBFM의 원거리 상호작용 계산의 가속화 알고리즘을 제안하였다. 대형구조의 전자기 특성해석을 위해서는 계산시간의 단축이 필수적이며, CBFM 해석법에서 원거리 블록 간의 상호작용을 다중극전개방법을 사용한 근사화를 통해 복잡도를 크게 감소시킨 수식을 도출하였다. 본 논문에서 제안된 새로운 알고리즘을 도체구와 전투기의 레이다 단면적 계산에 적용하여 기존의 CBFM과 비교하여 정확도 손실 없이 계산시간이 각각 34 %, 74 % 단축되어 대형구조 문제해석에 효율적이라는 것을 확인하였다. The characteristic basis function method, or CFBM, is one of the representative electromagnetic methods widely used today. In this paper, we propose an accelerating algorithm for the far field interaction calculation of CBFM, to efficiently analyze the electromagnetic characteristics of arbitrarily large structures. To effectively analyze the electromagnetic characteristics of a large structure, it is essential to shorten the computation time. In the CBFM analysis method, the complexity can be greatly reduced by using approximations created via the multipole expansion method. The new algorithm proposed in this paper is applied to the computation of radar cross sections of conductor spheres and fighter aircraft, and it is confirmed that calculation time is reduced by 34 % and 74 %, respectively, without loss of accuracy compared with existing CBFM.

본 연구는 경기도를 사례로 대학수학능력시험 성적 분포 특성을 분석한 것이다. 언어영역, 수리영역, 외국어영역의 수능성적 분포 특성과 그 변화를 살펴본 결과는 다음과 같다. 경기도는 수능성적의 분포가 지역별로 크게 차이가 나타났고, 특히 수능성적 분포의 시계열적 변화는 영역별로 다르게 나타났다. 그중에서 특히 외국어영역의 변화가 가장 컸다. 수능성적에 영향을 미치는 변수와 그 관련성은 요인 분석을 통해 추출하였다. 분석 결과 첫째, 시간이 지날수록 수능성적에 영향을 미치는 요인의 수는 증가했다. 둘째, 추출된 여러 요인들 중에서 경제·사회적 지위 요인이 수능성적에 가장 크게 영향을 미치고 있었다. 셋째, 외국어영역의 수능 성적 분포와 경제·사회적 요인 점수의 분포가 공간적으로 서로 일치하는 경향을 보였다. 이 둘 간의 높은 공간적 관련성은 유사 성격을 갖는 시·군 지역의 군집화 결과에서도 확인되었다. This paper examines distributional characteristics of scores in CSAT(College Scholastic Ability Test) in Gyeonggi-Do(Province). The research on the distributional characteristics of 3 subjects test domain shows that the CSAT scores and the change in the distributional pattern are different among the cities and counties, which is the most notable in a foreign language(English) domain. The factors that have influences on the CSAT scores are extracted out of several statistical variables, which is done by factor analysis. The result shows that economic and social factor is the most crucial. And the distribution of CSAT English score is higly consistent with the areas of higher scored areas of socio-economic status factor. These interrelatedness is also found in the clustering of cities and counties which have similar social background.
