Dentigerous cysts are the most common type of developmental odontogenic cysts. They form as a result of a separation of the follicle from around the crown of an unerupted tooth. Usually this lesion can be asymptomatic. Such cysts are often discovered accidently on inspection of x-rays. In other advanced cases, cortical bone expansion, displacement of teeth, secondary infection can be observed. The treatment of dentigerous cyst is enucleation. And according to size, location of lesion and environmental structure marsupialization can be considered. However, Marsupialization takes long treatment time and, cystic tissues are remained so secondary surgery may be needed for total removal., Risks of oroantral fistula, damage on maxillary sinus wall and infraorbital nerve can be considered as complications of conventional surgical treatment of cysts located in maxillary sinus. We treated third molar origin dentogerous cyst located in maxillary sinus removing endoscopically both the tooth and an associated dentigerous cyst. We report our clinical experience with literature review.

Diesel PM can be controlled using Diesel Particulate Filter, which can effectively reduce the level of soot emissions to ambient background levels. In the Heavy Duty Diesel area, the Continuously Regeneration trap has been widely applied in the retrofit market. As the Special act for the improvement of air quality in the capital area, the retrofit program for DPF to used diesel vehicle has progressed favorably and there are currently over 1,000 of these DPF in use in retrofit applications in korea. These DPF comprise a specially formulated Diesel Oxidation Catalyst upstream of a DPF. The $NO_2$ generated by the DOC is used to combust the carbon collected in the DPF at low temperature. To certificate DPF device that is suitable to domestic circumstances, it is necessary to evaluate exactly the DPF devices according to the regulation of DPF certificate test procedure for retrofit(ministry of environment(MOE) announcement NO. 2005-16). To do so the understand of that regulation like the standard of PM reduction rate is needed. In this study the test procedure including test cycle and BPT test condition was examined and also the test result for specific DPF was analyzed. In every test like field test, PM reduction efficiency test and seoul-10 mode test, no defect could be showed.

박용희,유철상,Park,Yong-Hee,Yoo,Chul-Sang 한국방재학회 2008 한국방재학회논문집 Vol.8 No.4

본 연구에서는 IHACRES 모형을 이용하여 충주댐 유역 내 12개 지점에 대한 관측유량자료에 대한 평가를 수행하였다. 특히, IHACRES 모형의 매개변수 중 지형특성 관련 매개변수를 지역화 기법을 이용하여 정량화하고, 이를 대상유역인 충주댐 유역의 여러 수위 관측지점에 적용하는 과정을 함께 수행하였다. 본 연구의 결과를 정리하면 다음과 같다. (1) IHACRES 모형의 매개변수 중 기후특성을 반영하는 매개변수인 c, <TEX>$\tau_w{^0}$</TEX>, f는 유역 전체에 동일하게 결정하여 사용할 수 있음을 확인하였다. (2) IHACRES 모형의 지형특성 매개변수인 <TEX>$t_q,\;t_s,\;v_s$</TEX>는 지형특성인자인 유역면적, 유로연장, 하천경사, 유역경사와의 회귀분석을 통한 지역화를 통해 적절히 추정할 수 있음을 확인하였다. (3) 유역에 대해 일관되게 적용된 기후특성 매개변수와 지역화 과정을 통해 추정된 지형특성 매개변수를 이용하여 충주댐 유역 내 12개 수위관측지점에 대한 관측유량을 평가하였다. 그 결과 상안미, 영월 1 지점의 유량 자료가 상대적으로 정도가 높은 것으로 확인되었고, 영월, 백옥포, 판운 지점의 경우는 유출자료의 품질이 상대적으로 낮은 것으로 파악되었다. 전체적으로 보면 고려된 12개 지점의 관측품질에 많은 차이가 확인되며, 따라서 보다 일관된 관측품질의 확보를 위한 방안의 마련이 시급함을 판단할 수 있었다. This study evaluated the runoff data collected at 12 stream gauge stations of the Chungjoo dam basin using the IHACRES model. Especially, the geomorphology-related parameters of the IHACRES model could be quantified base on the regionalization technique, which have also been applied many stream gauge stations of the Chungjoo dam basin. Summarizing the results is as follows. (1) The climate-related parameters of the IHACRES model c, <TEX>$\tau_w{^0}$</TEX>, and f are found to be estimated and used uniformly over the basin. (2) The geomorphology-related parameters of the IHACRES model <TEX>$t_q,\;t_s,\;and\;v_s$</TEX> are found to be estimated by considering the geomorphological parameters like the basin area, channel length, channel slope, basin slope through the regionalization based on the regression analysis. (3) Using the climate-related parameters applied uniformly over the basin and the geomorphology-related parameters estimated based on the regionalization procedure for each stream gauge station, a total of 12 stream gauge stations have been evaluated with their stream flow measurements. As results, the Sanganmi and Youngwal 1 stream gauge stations have been found to make high quality flow data, but Youngwal, Baekokpo, and Panwoon stations low quality flow data. On the whole, 12 stream gauge stations considered show large differences with their data quality, so a plan for securing more consistent data quality should be prepared imminently.

A Comparison of comparison: A Comparative Study of the Islamic and European Civilization by Carl Heinrich Becker and Max Weber During the 19th and early 20th century, a comparative study of civilizations had not been a popular subject for scholarly concern. Carl Heinrich Becker, a famous Orientalist and minister in the Weimar Republic, not only had a specialty in the Islamic economic history but also dealt with the universal development of the European and Islamic civilization. Although trying to show the relationship between two civilizations, he did not articulate a distinct way that the Islamic civilization had maintained. While he attempted to combine the later Classical age and Hellenism with the first centuries of Islam, he argued that the Islamic civilization went wrong since the Renaissance and Reformation. By contrast, he regarded the European civilization as one based upon the universal development of humanity. Therefore, his view of civilizations was basically eurocentric. Another pioneer in the field of a comparative study was Max Weber, whose sociology of religion mainly assumed comparative approach. His sociology of religion arose from an attempt to understand a series of innovations of what we are pleased to call modernity, which was emerging in European societies. In seeking to explain capitalist development in Europe he analyzed the economic ethics of religion, socio-political organization, the legal system and so forth. Because he found it hard to comprehend the identity of such development due to its uniqueness, he delved into the European development in comparison with the Islamic way of development. Despite his enormous effor, the origins of modernity still remain mysterious. However, I believe that Max Weber`s attempt was admirable considering that his methods of asymmetrical and hermeneutical comparison allow us to appreciate and example of non-eurocentric view of other civilizations.

The purpose of this paper is to analyse the service quality and customer satisfaction, loyalty of car insurance’s non-face-to-face sales channels. This study can be summarized as follows. Firstly, sub factors of usability in service quality are composed of consensuality, adaptability, corporeity, cost and confirmability and Hypothesis H1 was accepted. Secondly, usability in non-face-to face channels has a positive effect on loyalty and consumer satisfaction. According to the empirical tests, Hypothesis H2 and H3 were accepted. Thirdly, loyalty in non-face-to face channels has not a positive effect on consumer satisfaction contrary to our expectation and Hypothesis H4 was rejected. Usually a relationship between loyalty and consumer satisfaction is positive. But this relationship is available after the compensation of car accidents. Because consumers are only satisfied with more than compensation that they anticipated. Finally, there are two implications. One is that government authority should regulate incomplete non-face-to face channels in auto insurance to reduce weak point of it. The other is that insurance company should note that more important confirmability in path analysis. Consumers trust the insurance company only when they can confirm their compensation after car accident.

개인 맞춤형 추천모듈을 위한 전신 신체사이즈 추출

박용희(Park, Yong-Hee),진성아(Chin, Seong-Ah) 한국산학기술학회 2010 한국산학기술학회논문지 Vol.11 No.12

인체측정학(Anthropometry)은 자동차, 가전제품, 의료기기 및 스포츠 용품 등 다양한 분야에서 소비자의 만족 도와 사용 효율성을 최적화하기 위해 조사되고 연구되어 왔다. 하지만 아직까지 인체 측정 방식은 계측자를 이용한 직접측정 또는 스캐너나 디지털 측정기 등 고가의 장치에 의존적인 방법에서 벗어나지 못하고 있다. 따라서 본 연구 는 사진으로부터 신체인식 알고리즘을 이용하여 신체사이즈를 자동으로 추출하고, 의류추천 및 자전거 피팅사이즈 서 비스 등에 활용가능성을 제시한다. 이를 위해 Haar-like features와 AdaBoost 알고리즘을 이용하여 빠른 속도와 높은 정확도로 영상콘텐츠 내에서 신체 영역을 검출한다. 이후 AAM(Active Appearance Model)을 이용하여 특징점을 검출 하고 도출된 측정치에 최적화된 상품을 추천하는 지능형 모듈 시스템을 구현하고 성능평가를 제시한다. Anthropometry has been broadly explored in various fields including automobile industry, home electronic appliances, medical appliances and sports goods with aiming at reaching satisfaction to consumer's need and efficiency. However, current technologies to measure a human body still have barriers in which the methods mostly seem to be contingent on expensive devices such as scanner and digital measuring instruments and to be directly touchable to the body when obtaining body size.. Therefore, in this paper, we present a general method to automatically extract size of body from a real body image acquired from a camera and to utilize it into recommend systems including clothing and bicycle fitting. At first, Haar-like features and AdaBoost algorithm are employed to detect body position. Then features of body can be recognized using AAM. Finally clothing and bicycle recommending modules have been implemented and experimented to validate the proposed method.

한국인의 중국문화 인식

박용희(Yong-Hee Park) 한국문화관광학회 2003 문화관광연구 Vol.5 No.1

In this paper travel writings are treated as a representation and appropriation of other culture by tourists. By analyzing six Korean’s travel writing it reveals that the Korean tourists showed the tendency to admit Chinese culture as an other culture and went so far as to demonstrate their sympathy to the Chinese and belief in the past and present of the Chinese history. And in an understanding of China their viewpoint was filled with the nationalistic emotionalism. Therefore, they remembered the activities of the Korean nationalists in China. But each tourist situation expresses a distinct range of the concerns with difference. What is evident is that the sexual differences is conducive to the heterogeneity of the Korean perception of China. Especially women paid attention to the seemingly trivial affairs such as everyday life of common people and the state of women in China.

이슬람 문화의 역사적 이해

박용희(Yong hee Park) 한국독일사학회 2001 독일연구 Vol.- No.1

Unter Ablehnung des Fachverständnisses der Orientalistik, das den Vorrang linguistischer Studien betonte, unternahmen einige Islamwissenschaftler wie J. Wellhausen, I. Goldziher, M. Hartmann, C. H. Becker zwischen 1880-1930 eine historische Rekonstruktion des islamischen Orients. Sie betrachteten den islamischen Orient nicht mehr als eine gegnerische politische Macht oder als eine exotische und seltsame Gröβe im Nahen Osten, sondern als eine kulturelle Einheit, die historisch entstanden sei. So entstand eine Grundlage für das rationale Verstehen der fremden Welt. Man kann dennoch nicht sagen, dass ihre Arbeit in völlig neutraler und objektiver Weise erfolgte. Es war bei den Akademikern trotz ihrer objektivistischen Zielsetzung unvermeidbar, den Islam überwiegend aus eigener Perspektive zu verstehen. Vier grundlegende Denkstrukturen spielten bei ihrer Islamwahrnehmung entscheidende Rolle. Erstens können Religionen als ein von Menschen geschaffenes Glaubens- und Handlungssystem angesehen werden. Unter dieser säkularistischen Prämisse beschäftigten sie sich mit der ethischen Seite des Islam. Ferner fanden sie im Nationalstaat ein ideales politisches System der Menschheit. So spielte die nationalstaatliche Implikation bei ihrer Islambetrachtung eine große Rolle. Und die Wissenschaftler konnten nicht von der damaligen Forderung nach ökonomischem Interesse Deutschlands im Orient frei sein. Am wichtigsten ist ihre universalhistorische Perspektive, die die allgemeine Entwicklung der Menschheit zur modernen Gesellschaft voraussetzt. Sie unterschieden eine fortschrittliche Entwicklung in den Anfängen der islamischen Zivilisation und eine Stagnation und Rückständigkeit in der Gegenwart. Insbesondere waren sie der Meinung, dass sich der Orient in seiner gegenwärtigen Lage in einem religionsbedingt erstarrten und rückständigen Zustand befände, so dass eine religiöse Reform dringend erforderlich sei. Trotz kritischer Vorbehalte sollten diese Denkstrukturen nicht bloß als eine steife Denkweise eingeschätzt werden, die von allen denkbaren Vorurteilen durchdrungen ist. Ihre Vorstellung wurde im Vergleich zu anderen damaligen Islamkennern durch ihre liberale und universalistische Einstellung abgemildert. Es herrscht auch ein Humanismus vor, der die Andersartigkeit der anderen Kultur verstehen wollte.
