  • 웹 환경에서의 지도서비스 및 위치기반서비스를 제공하기 위해서는 다축척 지도 데이터베이스를 구축하여야 하나, 제작과정이 아직까지 수동편집에 의존하는 경우가 많았다. 본 연구에서는 기본 지도 자료로부터 다축척 지도 데이터베이스를 자동으로 구축하기 위한 지도 일반화 기법을 제안하고 이를 실제 지도 데이터에 적용하여 프로토타입의 다축척 지도 데이터셋을 생성하고자 한다. 지도 일반화 기법으로는 선택 및 삭제, 단순화, 병합 등의 연산자를 조합하여 적용하였으며, 각각 연산자의 알고리듬과 파라미터들은 T$\ddot{o}$pfer's radical law, 지도의 최소도화 기준, 시각적 표현정도 등을 종합적으로 고려하여 실험적으로 결정하였다. 목표 축척수준은 1:1,000, 1:5,000, 1:25,000, 1:100,000, 1:500,000 의 5단계로 설정하였으며, 대상이 되는 기본 지도 자료는 도로명주소 전자지도와 수치지형도를 사용하였다.

  • Objectives: The hazardous heavy metal contents of cosmetics were investigated and the resulting values were compared by type of cosmetics: skin care preparations (SCP), hair preparations (HP), makeup preparations (MP), and eye makeup preparations (EMP). Methods: The hazardous heavy metal contents (Pb, As, Cd, Sb, Ni and Hg) were analyzed for 358 cosmetics products (187 SCP, 82 HP, 56 MP, and 33 EMP). Hg was measured by the amalgamation method, and other hazardous heavy metals were measured by inductively coupled plasma optical emission spectrometer (ICP-OES) after decomposition using the microwave method. Results: The mean contents of Pb, As, Cd, Sb, Ni, and Hg in cosmetics were 0.424, 0.068, 0.024, 0.398, $0.567{\mu}/g$, and Not Detected, respectively. All of the hazardous heavy metals were detected in most products, but below the recommended maximums of the Ministry of Food and Drug Safety. The level of Cd was the lowest at 14.8%, and Sb was the highest at 41.2%. Pb, Sb and Ni showed the highest mean value and detection rate in EMP. As, Cd, and Hg showed the highest in SCP, HP, and MP, respectively. Conclusion: Hazardous heavy metals were detected in most products. In particular, Pb, Sb, and Ni were broadly detected in EMP, meaning more stringent quality control is required.

  • The central-western Korean Peninsula contains records of an Early Mesozoic collisional event related to the final amalgamation of the East Asian continent. Here, we present a renewed geologic map of the Deokjeok and Soya islands in the central-western Korean Peninsula and its explanatory note. Our geologic map was based on a detailed investigation of the northeastern area of both islands, which is characterized by a complex fault and shear zone system that accommodated the crustal deformation related to the Mesozoic post-collisional orogenic collapse and the subsequent structural inversion. We suggest future directions of study aiming at addressing issues regarding the deformational responses of crust to the Mesozoic tectonic transition and orogenic cycles.

  • A multi-dimensional design is most easily constructed via the amalgamation of one-dimensional component block designs. However, not all sets of component designs are compatible to be amalgamated. The conditions for compatibility are related to the concept of a complete matching in a graph. In this paper, we give sufficient conditions for unequal-replicate designs. Two types of conditions are proposed; one is based on the number of verices adjacent to at least one vertex and the other is ona a degree of vertex, in a bipartite graph. The former is an extension of the sufficient conditions of equal-replicate designs given by Dean an Lewis (1988).

  • Currently in the Web(World Wide Web) environment, HTML(Hyper Text Markup Language) is used for information representation and exchange. But it is thought that HTML has some constraints in information representation of various kinds because of its limited tag set. And it is considered that combining the HTML, which is used for static information representation in Web environment, with Scripting language, which is usually used for multimedia information representation in a synchronized framework, can be very useful. Consequently we show the general trend of the Scripting language in Web environment and show the possibility of HTML and Scripting language amalgamation for Web service improvement.

  • Electrical behaviors of the divalent silver oxide-zinc cell were analyzed for imporving capacity and keeping electrodes from passivation or sharp increases of cell internal resistance in the course of discharge. One of primary factors in relation to lowering performance can be depicted by cell internal resistance increase being created by various routes, first by insufficiency and/or the carbonation of the electrolyte, secondly by barrier blockage, thirdly by electrode passivation which are due to improper material use of wrong processing, and by gassing as fourth cause. The carbonation causes electrobyte to have impedance up as well as poor amalgamation, resulting in vigorous corrosion reaction of copper plated inner top, evolving hydrogen gas. Electrical characteristics of the cell was reviewed to elucidate relationships between the discharge capacity and the cell internal resistance.

  • This study is processing to analyze the causes and to suggest the solution about extension of closed schools which comes from urban decay in the city. The meaning of this report is based on the purpose to help the substantial application of the equipments of closed schools. This is used by groping the composite application scheme for improving the values of recycling facilities of closed schools which is according to abolition and amalgamation. To complete the purpose of this report, many documents, records and corroborative evidences were used to process this study. We suggest the program that is available to invest space. That is analyzed the environment and the social application that the building has is proper or not.

  • 본 연구는 근대이후 서울시 성북동의 문화재와 주변 경관 변화과정과 원인을 분석하고자 하였으며 시대별 폐쇄지적도를 이용한 필지 분석과 문헌자료를 참고하여 연구하였다. 경관은 대체로 제도적 요인과 사회경제적 요인에 의해 변화가 생기는 것을 알 수 있었다. 근대 이후 서울의 도시계획이 성북동에도 영향을 미쳤으리라 예상되며, 자본주의 경제체제 확립이 그 배경이 된 것이라 판단된다.

  • Ayurveda is often criticized for having empirical and non-evidence based approach to treat the patients. At the same time, modern medicine is also being criticized for having a non-holistic, reductionist and mechanistic approach of treating the patients which do not help in many real clinical situations. An open minded deduction of treatment approaches in both of these systems for a common patient however makes us to rethink that ideally both systems are similar with a common objective of offering a cure although in a manner which is better understood through their own methods of learning. The differences therefore, are more superficial rather than being deeply rooted in the understanding. A more tolerant viewpoint towards the competitive medical systems may therefore be a better approach to offer optimal health care to our people through a genuine amalgamation of these two health care sciences through an integrated approach. Once this tolerance is developed, it will give us an opportunity to think for a focused selection of type of health care depending upon the type of the disease and strength of the particular system in that area.

  • 0.1%-Merthiolate solutions were applied to rats with or without sodium selenite. Rat organs were excised under ether anesthesia. Mercury contents in rat tissues were determined by quartz tube combustion gold amalgamation method. Mercury contents were accumulated at about 3-fold in the brain, 143-fold in the kidney, 62-fold in the blood cell, 22-fold in the liver than those of untreated rats respectively, on the 1st day after application of mert iolate for 7 days. On the other hand, the addition of sodium selenite caused a shift in the tissue mercury distribution. Our study showed that simultaneous administration of sodium selenite increased the accumulation of mercury in the brain, but became to decrease it after 9 days, while decreased it in the kidney, but grew to increase it, respectively.
