  • The global nematicides market is expected to continue growing. With an increasing demand for synthetic chemical-free organic foods, botanical nematicides are taking the lead as replacements. Consequently, in the recent years, there have been vigorous efforts towards identification of the active secondary metabolites from various plants. These include mostly glucosinolates and their hydrolysis products such as isothiocyanates; flavonoids, alkaloids, limonoids, quassinoids, saponins, and the more recently probed essential oils, among others. And despite their overwhelming potential, variabilities in quality, efficacy, potency and composition continue to persist, and commercialization of new botanical nematicides is still lagging. Herein, we have reviewed the history of botanical nematicides and regional progresses, the potency of the identified phytochemicals from the key important plant families, and deciphered some of the impediments involved in standardization of the active compounds in addition to the concerns over the safety of the purified compounds to non-target microbial communities.

  • This paper examines professional and popular medical discourse on "mongolism" (Down syndrome) in the early twentieth century to delve into the history of mongolism and the "Oriental imaginary" of modern America. The Oriental imaginary is a concept to explore the ways in which Americans, who had heard of mongolism or seen a "Mongol" themselves, imagined and conceptualized the defect in terms of the contemporary race relations. Moving beyond the interests of medical professionals discussed in the previous scholarship, this paper aims to include views and perceptions of the American public. The second section reviews the existing studies of the history of mongolism in the West. The third section discusses the mongolism of Asians and African Americans, among whom it had long been believed not to occur. Lastly, an analysis of American newspaper health advice columns on mongolism sheds light on the public reception and transmission of medical knowledge.

  • Recognizing that the debate on the original form of the Seokguram Grotto is closely related to the mythologization of the Seokguram Grotto, which is far from factual understanding, this paper is prepared to restore the Seokguram Grotto based on scientific facts. To this end, we will first analyze its active meaning and fiction from three directions: the founding legend, the rediscovery story, and the concept and discourse of the Line of sight for Buddha statue (對佛像視準線), which have contributed to the mythologization of the Seokguram Grotto. The original restoration of the Seokguram Grotto should be based on a scientific understanding of the Seokguram space. However, past debates and restoration attempts have been based on imagination and not on scientific knowledge. Therefore, Chapter 3 attempts a scientific analysis of the light environment of thr Seokguram Grotto and critically examines the existing errors and realistic mythological images to correct the public's spatial perception of Seokguram's architecture and to propose a rational restoration of Seokguram's architectural space.

  • This year(2012) marks the 30th anniversary of the Malvinas (Falkland) war. A series of talks between the British and Argentina took place over 30 years until 1982, but failed to reach a conclusion on sovereignty. Argentina claims that sovereignty of the islands was transferred to Argentina from Spain upon independence, a principle known as uti possidetis juris. But UK claims that the principle of uti possidetis juris is not accepted as a general principal of international law, and UN General Assembly resolutions calling for negotiations are flawed because they make no reference to the islanders' right to choose their own future. In this situation, a huge amount of petroleum and natural gas has discovered near the Malvinas islands. To explore such situation, this article looks into history and present condition on dispute of Malvinas sovereignty, and also analyses de-colonialism and resource nationalism related to dispute of Malvinas sovereignty.

  • Objectives : The acupoint-meridian relationship of an acupoint is one of important features of the acupoint. It has also shown evolutionary development over the history of medicine. This study analyzed the prototype kind of information on acupoint-meridian relationships in the A-B Classic of Acupuncture and Moxibustion(the Classic) of 2c BCE. Methods : The acupoint-meridian relationship of all the acupoints listed in the Classic was counted and reviewed in comparison with the information in the contemporary standard texts. Results : In comparison with the contemporary standard of 361 meridian points, the Classic listed 349(97%) acupoints. Of contemporary standard 361 points, 287(81%) acupoints still maintain the same acupoint-meridian relationship as in the Classic. Conclusions : Acupoint-meridian relationship in the Classic has largely been maintained throughout the history and still comprises a major proportion of the contemporary body of knowledge on acupoint-meridian relationship.

  • Computerized visual database construction of architectural precedents has just begun in some research institutes in the world. In Korea the first visual database has shown its testl version by S architectural design firm in september 1996. In this article the author discusses the historical contexts and the recent computerization cases, the traits, the uses and the limits of architectural visual database system of precedents. The forms and contents of data fields in two cases are compared with a focus on the description of architectural traits of each data entry. Compared to the KIA format, the S database has better performance for architectural design reference because it collects more pictures and drawings and larger texts for the field of architectural chracteristics. But this latter also is constrained by its capacity of memory and so lacks the reciprocity of the DOORS in the Graduate School of Design, Harvard University. A visual database system which has more flexible allocation of memory and respondent with the users is yet to be prepared. But this system also should be maintained by some experts in architectural history, theory and criticism, because their knowledge is essential for selection of precedents and revision of the data description. A full-fledged electronic visual database in architecture will not only save much effort for the architect, but also will change the architects' design behavior. Nevertheless this does not mean the automatic promotion of architects' creativity.

  • Under the WTO system, global standardization of professionalism in architecture practice calls for transformation of curriculum in architectural education in Korea. This paper compares the curriculum standards of international accrediting authorities such as NAAB and RIBA based on UIA accord which defines fundamental knowledge and abilities of an architect. As a result this paper extracts 51 achievement oriented criteria of architectural education in Korea. It can be categorized as communication, design, cultural context(history and theory, human behavior and social aspects), technical systems(structural systems, environmental control systems, construction material and assemblies) and practice(project process, project economics and business management, laws and regulations). Based on this recommended Korean curriculum standards, current curriculum is analyzed focusing on the 5 architectural programs in Seoul. Through this analysis, it became clear that some area - social and economic aspects in architecture, sustainability in architecture, understanding and selection of construction material, assemblies and environmental control system, recycling of existing building, professional liability, professional rules of conduct, project economics and project management - need to be covered and emphasized to meet the international standards in professional education in architecture. The result in this paper will be used as a basic data in the process of finding the direction of restructuring curriculum for professional architectural education in Korea.

  • The smallpox or chanjin(瘡疹), from Korea Dynasty when the name concretely is discussed to Joseon Dynasty, was very one of the diseases which were important. Not only the public but also the royal family could not avoid the pain which is caused by with the smallpox. Also as a scar and fear that the smallpox leave on, the smallpox was called a God(痘瘡神). As the prayer and sacrificial rites primarily could not relieve the nation and the community from a smallpox, an intellectual finally had to remind that if people considered a factor which caused the smallpox, they could cure this disease. That was Nam Hyoon(南孝溫) who rejected a goast to cause a smallpox. And the compilation of "Changjinjip(瘡疹集)" changed recognition about a smallpox. Especially, the compilation of "Changjinjip" was very important in the history of Korean medicine. Because it told what "Uibanglyuchui(醫方類聚)" the national compilation project of medicine book that King Sejong promoted leaved. The "Changjinjip(瘡疹集)" adopted two kind methods. The one was the medical history or with medical theoretic history method: arranged a various medical theory about "changjin" like "Uibanglyuchui". The other was the clinical method of presenting theories and prescriptions as causes and mutations: reformed contents of "Uibanglyuchui". In addition to special medicine book of smallpox, "Changjinjip" gave knowledge about a paradigm of "Uibanglyuchui" and methods of medical book compilation in later.

  • 퍼지 논리는 1965년 Zadeh([13])에 의하여 소개된 이후 꾸준히 확장, 발전하였다. 퍼지 논리와 관련된 수학사 및 수학교육 논문([1], [2], [3], [4], [5], [7])들이 많이 발표되었지만 정작 퍼지 논리의 창시자인 Zadeh에 대한 연구 논문은 아직 발표되지 않았다. 본 논문에서는 Zadeh의 생애와 업적을 알아보고 이를 통해 우리가 배워야 할 점들에 대해 논의한다. 또한 이가 논리, 다가 논리, 퍼지 논리, 직관주의 논리 및 직관적 퍼지 집합을 비교, 분석하고 직관적 퍼지 집합에서 '직관적(intuitionistic)' 이라는 용어의 부적절성에 대해 논의한다.
