This paper presents an overall image processing approach of defect inspection of patterned TFT-LCD panels for the real manufacturing process. A prototype of AOI(Automatic Optical Inspection) system which is composed of air floating stage and multi line scan cameras is developed. Adjacent pattern comparison algorithm is enhanced and used for pattern elimination to extract defects in the patterned image of TFT-LCD panels. New region merging algorithm which is based on border expansion is proposed to identify defects from the pattern eliminated defect image. Experimental results show that a developed AOI system has acceptable performance and the proposed algorithm reduces environmental effects and processing time effectively for applying to the real manufacturing process.

The cross-border trade(CBT) market has grown significantly due to the global spread of the Internet and mobile. China has become a very important market because of its share of 78% in 2016 in the export of korea's CBT. To sum up this phenomenon, First, the forms of distribution and trade, in which the O2O method is utilized, are settled. Next, it is necessary to develop a new strategy to expand the stagnant export of Korea. In particular, it is time to look for an effective export expansion strategy to expand market share in the fast-growing Chinese market. For this purpose, this study proposed a strategy for efficient use of logistics as a countermeasure against China's CBT laws and regulations and development of CBT exports to China to develop effective export strategies.

District of Korea affected by westerly wind and heavy rainfall is predominantly distributed in the west and south of Honam district. So, this study is becoming a necessity. In this study, it is investigated that the characteristics of heavy rainfall occurred frequently in Honam district along the border of mT airmass after the end of rainy season due to atmospheric instability, lower (850 hPa) convergence and topographic effect. Our results show that heavy rainfall occurred in Honam district along the border of mT airmass results from the appropriate mechanism of the unstable vertical structure and moisture flux in the expansion and contraction of the border of mT airmass. All things considered, the improvement of the predictability of heavy rainfall occurred in Honam district along the border of mT airmass could be possible by the generalization of the results of this study.

미국의 지원 하에 추진된 우리베 정권(Alvaro Uribe:2002-2010)의 마약퇴치 및 불법무장조직에 대한 강경책은 가시적 성과에도 불구하고 마약과 관련된 범죄는 증가했으며, 마약재배와 거래량의 변화를 동반하지 않았다. 오히려 불법작물 재배권을 둘러싼 좌.우익 불법무장단체들의 무력분쟁은 심화되었고, 강제실향민으로 인한 난민은 급증했다. 2005년 실향민등록위원회 RUPD(el Registro Único de Población Desplazada)는 콜롬비아 전체인구의 7.3%에 해당하는 3,316,862명이 난민상태라고 보고했다. 특히 2002년 강제실향민으로 인한 난민 수는 전년대비 624%의 대폭적인 증가율을 나타냈다. 강제실향민 주요 배출지역은 마약범죄와 불법무장조직의 활동과 관련을 맺고 있는 곳으로 불법무장단체와 민병대의 점령지 확장과정에서 무력분쟁이 지속적으로 증가했다. 불법무장조직과 민병대가 불법작물경작지를 차지하는 과정에서 농민에 대한 무차별적인 공격을 감행하여 강제실향민이 급증하였고, 이들은 상주지를 떠나 국경을 넘어 접경지역으로 이동했다. 2002년 우리베 정권이 등장하기 이전 강제실향민문제는 일부 특정지역에 국한되었지만, 국가안보정책 추진이후 강제실향민은 양적인 팽창뿐만 아니라, 전국적으로 확산되는 경향을 나타냈다. 마약거래의 주요 루트였던 아마존 지역이 폐쇄되자 불법무장조직의 활동거점이 태평양 역으로 이동되었고, 특히 파나마 접경지역은 이전에 존재하지 않았던 강제실향민으로 인한 콜롬비아 난민이 증가했다. 본 연구는 2002년 우리베 정권등장 이후 증가한 국경지역 강제실향민을 대상으로 콜롬비아 난민증가 원인에 대해 고찰해 보고자 한다. 역사적으로 콜롬비아의 강제실향민이 가장 많이 분포되어 있는 베네수엘라와 1990년대 말 이후 강제실향민의 새로운 정착지로 변모한 파나마 그리고 2000년 들어 다른 인접국보다도 급격하게 증가한 에콰도르 접경지역의 강제실향민을 중심으로 강제실향민 증가원인을 고찰하고 이를 바탕으로 난민문제 해결을 위한 콜롬비아 정부의 노력을 살펴볼 것이다.

Purpose : To acquire the useful diagnostic information through the analysis of the clinical and radiological characteristics of mandibular odontogenic keratocyst. Materials and Methods : The researchers compared and analysed the clinical and radiological features of 112 cases of mandibular odontogenic keratocyst confirmed by histopathlogic examination. Results : Mandibular odontogenic keratocysts occurred more frequently in males than in females and the incidence is the highest in the 2nd and 3rd decades. These cysts occurred in the mandibular posterior area, angle-ramus area and anterior area $51.8\%$, $31.2\%$ and $17.0\%$ respectively. These cysts had undulating border ($69.6\%$) rather than smooth border ($30.4\%$). Most of these cysts had well-defined hyperostotic border ($94.6\%$). These cysts caused cortical thinning or expansion ($78.6\%$) rather than no cortical reaction ($21.4\%$). Loss of lamina dura was observed in $72.3\%$, displacement of tooth appeared in $35.7\%$ and root resolution appeared in $12.5\%$ of cases. In $71\%$ of cases, displacement of mandibular canal was observed. Internal patterns of lesional radiolucency were even ($61.6\%$) or uneven ($38.4\%$). Conclusion : These results would be helpful in diagnosing of mandibular odontogenic keratocyst. (Korean J Oral Maxillofac Radiol 2005; 35 : 51-4)

The purpose of this study was to obtain some informations for the radiographic differential diagnosis between dentigerous cysts and unicystic ameloblastomas in the mandible. The authors observed and compared the clinico-radiographic features of 38 cases of dentigerous cyst and 32 cases of unicystic ameloblastoma associated with impacted mandibular molar. The obtained results were as follows: Dentigerous cysts occurred the most frequently in the 3rd decade, but unicystic ameloblastomas in the 2nd decade, and both lesions occurred with slight predilection in males. Average of lesional size of unicystic ameloblastomas was larger than that of dentigerous cysts, and lesions of over 25㎠ were only in unicystic ameloblastomas. Cortical thinning and expansion were more frequently observed in unicystic ameloblastomas at 72.9% than in dentigerous cysts at 15.8%. Dentigerous cysts showed smooth border at 89.5%, but unicystic ameloblastomas showed smooth border at 53.1% and scalloped border at 46.9%. Dentigerous cysts showed well-defined outline at 81.6%, but unicystic ameloblastomas showed well-defined outline at 53.1% and moderate-defined outline at 46.9%. In both lesions, the mandibular 3rd molar was the most frequent causative tooth. Average of distance between the cemento-enamel junction and lesional wall attachment of the causative tooth was longer in unicystic ameloblastomas than in dentigerous cysts. Severe displacement of causative tooth was more frequent in unicystic ameloblastomas at 62.5% than in dentigerous cysts at 23.7%. Dentigerous cysts showed homogeneous lesional radiolucency at 89.5%, but unicystic ameloblastomas showed inhomogeneous lesional radiolucency at 53.1%. Root resorption of adjacent tooth and displacement of mandibular canal were more frequent in unicystic ameloblastomas at 65.2% and 61.5% than in dentigerous cysts at 15.8% and 38.1% respectively.

Many States such as Arizona, Texas, New Mexico, Colorado, California, New Mexico, Florida were obtained either from Spanish Empire or from Mexico. In 1848 due to the Guadalupe-Hidalgo treaty America could obtain half of the original territory of Mexico. American identity cannot be understood without the history of American expansionism further consolidated by the Spanish-American War in 1898, which brought other ex-Spanish colonies such as Guam, Puerto Rico, the Philippines to the US. The US's interest in these territories dates back to the Monroe doctrine in 1823 when Monroe "declared the Americas off-limits to any new European colonization." America justifies their expansion based on the notion of Manifest Destiny which was created by O'Sullivan at the hight of American fever to annex Texas to US. The intent of this paper is to study how Anglo-Saxon and Latin Culture clashed against each other especially right before and after the Spanish-American War. In this study the American hero, Theodore Roosevelt and Latin American hero, $Jos{\acute{e}}$ Martí will be compared, though they did not meet each other during the Spanish-American war due to Marti's early death in 1895 at the battle for the Cuba Libre. Their comparison is significant in that the former represents the American expansionist spirit and the latter the spirit of Anti-imperialism and Anti-Anglocentrism. Along with the concept of Manifest Destiny of America, 'American exceptionalism' is also mentioned which motivates U.S. to expand further even after the Spanish-American war in the form of 'informal imperialism' characterized by 'gunboat politics'of the US. These discussions will draw attention to how recent theorists such as Bryce Traister criticizes the Border Theory represented by $Jos{\acute{e}}$ David Saldívar. Here the Border Theory is criticized to repeat the discourse of the globalized capitalism which prefers the weak state and the transnational aspects by focusing on the in-betweenness of the border. In the end the paper will focus on how the Border theory as represented by Saldivar is political enough and sets up a resistant example against American expansionism of today in its focus on the call for pan-American and pluri-versal subjectivity of the borderlands. This point will be supported by a discussion of how Saldivar's view is confirmed by Walter Mignolo who advocates the "bottom up" resistance of the indigenous people of Chiapas and other social forums such as World Social Forum and the Social Forum of the Americas derived from the Zapatistas' movement whose motto is "A World in which many world co-exist."

대전은 중 저산성 산지로 둘러싸인 사각형 모양의 분지에 입지한 도시이다. 분지 내에는 갑천과 그 주요 지류인 유등천 대전천이 흐른다. 분지 내 하천들 주위에는 비교적 넓은 저습지가 발달해 있으며, 이러한 저습지를 포함한 하곡들 사이에는 낮은 구릉들이 펼쳐져 있다. 이와 같이 대전 분지는 여러 개의 작은 분지 및 곡저 평야가 복합된 모습을 보인다. 한편, 대전 분지와 관련된 거주 공간 및 시가지 확산은 분지 언저리에서 시작하여 분지 내부의 갑천 지류 주변의 저습지로 확산되었다. 그리고, 시가지화가 이곳에 이루어진 후에는 대전 분지 북부 대덕 지역의 구릉 및 갑천 하곡으로 확산되었다. 그 후 대전의 시가지는 다시 분지 내 갑천의 저습지와 이에 인근한 분지 서남부에서 서북부에 이르는 산록대 소규모 분지들이 시가지화 하거나 또는 고밀도 거주단지로 바뀌고 있다. 이와 같이 대전 분지와 관련된 거주 공간 및 시가지 확산은 지형 환경을 밑그림으로 하여 살펴볼 때 더욱 잘 파악할 수 있다.
