Purpose: To describe curved planar reconstruction imaging (CPRI) and determine its usefulness in the evaluation of focal cortical dysplasia of the brain. Materials and Methods: In 17 cases of focal cortical dysplasia [cortical dysplasia (n=9), schizencephaly (n=5), and heterotopia (n=3)], CPR images were created using a multiplanar reconstruction program and imaging data obtained during T1 magnetizationprepared rapid acquisition gradient-echo MR imaging. We assessed the precise configuration of abnormalities and their relation to adjacent gyri and sulci. Results: CPRI showed the brain cortex as a 2D panoramic image, demonstrating the precise configurations and locations of dysplasia-associated abnormalities and their relation to adjacent gyri and sulci, and the precise shape of the gray-white matter interface. Conclusion: CPRI can provide important radiological information about the extension and configuration of focal cortical dysplasia, and its relation to neighboring cortical structures. We believe that CPRI should form an essential part of the routine investigation of suspected cases of focal cortical dysplasia. 목적:3차원 MR영상법으로 촬영된 MR데이터를 사용하여 곡면재구성영상을 얻어 국소적 뇌피질 이형성증을 평가하는데 유용성을 알아 보았다. 대상과 방법:국소적 뇌피질 이형성증 17명을 대상으로 하였고 뇌피질 이형성증(cortical dysplasia,n=9),분열뇌증(schizencephaly,n=5),이소성 회질증(gray matter heterotopias,n=3)이었다.곡면재구성영상은 자화준비고속경사에코획득을 이용하여 얻은 영상에서 곡면재구성프로그램을 이용하여 만들었다.곡면재구성영상에서 병변의 범위,모양,주위 정상 대뇌이랑,고랑과의 관련성을 분석하였다. 결과:곡면재구성영상은 뇌표면을 파노라믹 모양의 2차원으로 벌려 놓은 모양이었다. 17예의 국소적 뇌피질 이형성증 환자에서 곡면재구성영상은 이형성된 뇌피질의 위치와 모양,그리고 주위의 정상 대뇌이랑과 고랑과의 관계를 잘 보여 주었다. 결론:곡면재구성영상은 국소적 뇌피질 이형성증 환자에서 병변의 위치와 범위 그리고 주위 구조물사이의 중요한 방사선과적 그리고 해부학적 정보를 제공했다.국소적 뇌피질 이형성증이 의심될 때 곡면재구성영상은 일반적인 영상방법과 함께 포함되어야 할 검사법이다.

정경호,이보현,김성훈,Jeong, Gyeong-Ho,Lee, Bo-Hyeon,Kim, Seong-Hun 한국재료학회 1999 한국재료학회지 Vol.9 No.12

본 연구에서 FPC에 사용되는 동박과 접착제의 이종 재료간에 계면접착력을 향상시키기 위해 silane primer를 도입하였다. 또한 동박표면 및 에폭시 접착제를 개질하여 개질조건이 접착강도에 미치는 영향도 조사하였다. 본 실험은 접착제층과의 상용성을 고려하여 silane primer로 triethoxyvinylsilane을 용액 및 무유화제 유화중합한 고분자형태와 3-aminopropyl-triethoxysilane (3-APTES), 3-glycidoxypropylmethoxysilane (3-GPTMS)을 사용하여 접착제층과의 접착력 증진을 도모하였다. 동박표면은 1,1,1-trichloroethane을 사용하여 개질 시간에 따른 동박 표면의 지형변화와 그에 따른 접착강도를 조사하였다. 결과에 따르면 silane을 사용한 경우 동박-접착제간의 접착력이 약2 ~ 5배 정도 증진되었고, 동박표면의 개질시간은 약 10분 정도가 최적의 접착조건임을 알 수 있었다. 또한 저분자량 실란의 농도에 따른 접착력은 3-APTES는 약 0.5 vol.%에서 최고 접착력을 보였고, 3-GPTMS의 경우 약 0.2 vol.%에서 최고의 접착력을 보였다. In this study, the silane primers were introduced to improve the interface adhesion between copper and epoxy. Especially, the polymer types obtained by solution and emulsifier-free emulsion polymerization of vinyltriethoxysilane and the low molecular weight types of 3-aminopropyltriethoxysilane(3-APTES) and 3-glycidoxypropyltrimethoxysilane(3-GPTMS) were used to improve the adhesion strength between epoxy and copper. Also, the surface of copper was treated by 1,1,1-trichloroethane. According to the results, the interfacial adhesion strength of copper-epoxy increased about 2~5 times with the introduction of silane primer. Also, the optimum treatment time of copper surface was about 10 minutes. Additionally, the adhesion strength as a function of concentration of low molecular weight silane was maximum at about 0.5 vol.% for 3-APTES and about 0.2 vol% for 3-GPTMS.

3차원 근접정보를 이용한 검사시스템의 성능평가와 디자인 고려사항

Due to economical or technological reasons. humans are responsible for inspection functions in many cases. Humans. however. are rarely perfect. thus allowing non-confirming parts to be processed. As the attributes of interest or the variety of products increases. the inspection system becomes less effective because of the sensory and cognitive limitations of human inspectors. Any means that can support or aid the human inspectors is necessary to compensate for inspection difficulty. Augmented reality (AR) offers a new approach in designing an inspection system as a means to augment the cognitive capability of inspectors by providing the 3D spatial proximity between two information channels. The experimental results suggest that AR might be an effective tool that reduces inspection time without sacrificing the measuring accuracy.

This study is a Christian ethical reflection of “Food of Hospitality." It is very important for me to build Life-giving and Peace-making theology and ethics reflected upon “Food and Faith." First of all, I deal with Jacques's hospitality such as “Conditional hospitality" and “Unconditional hospitality" and then compare with Elizabeth Newman's hospitality such as “Sentimental hospitality", “Privatized hospitality", “Hospitality as mode of marketing", “Mere hospitality as inclusively" and “Homeless hospitality". I call “Homeless hospitality" as “Divine hospitality" here after. Then I try to find out various cultures of hospitality in global context, food of hospitality focusing on Abraham and Sarah in Genesis 18 and hospitality for global world. As a result of this study, it becomes evident that food of divine hospitality of Abraham and Sarah for the strangers is costly source of life and blessing. I am convinced that divine hospitality is holy duty, responsibility and faith because God so loved all life community, especially the stranger such as the poor, hungry, isolated, alienated people and life community in global world. I, therefore, conclude that we have to learn and practice our costly divine hospitality as beautiful life-giving faith and theological · faithful life for global peace, justice and all life community in fullness toward Reign of God.

This study is historical, theological and ethical interpretation of the Kim, Yak Yeon's faith and life for the new society and national independent under Japanese colonialism. First of all, my main emphasis is that how the Rev Kim affected and changed whole society as well as Myoung Dong rural village and church in Manchuria. For example, the Irish Presbyterian Mission in Manchuria in 1914 counted that some 500,000 Koreans immigrated in order to secure better conditions than Korean land under Japanese colonialism. The Rev. Kim made new village with cooperation. love and independent spirit; built girl's school as well as elementary and middle school for boys in Myoung Dong; accepted Christianity from Confucianism and built Myoung Dong Church; became significant national leader for independent country. Thus he was one of the most famous champion for faith for the new society and national liberation under Japanese colonialism. As a result of this study, it becomes evident that the Rev. Kim, Yak Yeon had followed national faith tradition not just missionary oriented conservative faith. It is why he bear the Cross on the shoulder and took national leadership such as a leader of national independent movement. new village movement and educator of Myoung Dong school as well as church pastor who was affected immigrated Korean people in Manchuria.

We can not trust any foods which give health and sustain our life today because they are polluted by life-threatening “pesticide” such as “germicide", “insecticide", “antibiotic", “acaricide", “herbicide", “gumigant", “trans-isoner fatty acids" “genetically modified organism"(GMO), “chemical seasoning", “food additive" such as “preservative" or “mono sodium glutamate"(MSG), “growth hormone", “endocrine disrupter", “melanin" in milk powder and candies or cakes for Children and so on. We have to know that they are life-threatening and life-killing foods. I, therefore, am going to study the foods of “Garden of Eden" that is perfect local foods and life-giving organic foods as well. Those foods were created by God as a farmer for Adam and Eve in the beginning of God's creation. I deal with three Christian ethical points about the foods of Eden. First, Adam and Eve make furrows, sow the seeds of barley, wheat, crop without any kind of chemical seasoning, pesticide, insecticide, herbicide and so on. Watching at the foods of Eden, we can not find out any kind of GMO, MSG and food additives. They are God's giving perfect, organic foods for life and local foods without any kind of “food miles" as well. Second, foods of Eden is to taste God's mysterious creation. The fresh vegetables and the fruits are God's abundant presents for Adam and Eve. These God's lovely presents come to their life and give unaccountable nutrition with sacrificial service. We can meet God through the foods of “Garden of Eden" because Adam and Eve meet God who loves the world and the universe through their foods of Eden. Accordingly, we taste God's mysterious creation, think about God's amazing grace and thank God's unlimited love for life community through the foods of Eden. Third, garden of Eden is the most joyous place to God and thus it is the happiest place to Adam and Eve. God creates every kind of vegetables, fruits, barley and wheat and plants in Eden, and let them care and manage them with the abundant life and peace. They live in peace, joy, happiness and abundant life with God. It's why “God sees everything that God had made, and indeed, it was very good."(Gen 1: 31) Unfortunately we confront every polluted foods of anti-Eden and anti-Life which is life-threatening foods to us. We also find out different kind of the injustice foods in global world such as wars, refugees, life-threatening poverty, natural destruction, and life-killing HIV/AIDS and other serious diseases. Therefore, we have to spread out costly God's reign in the global world toward the abundant life and peace in fullness against life-threatening and life-killing reality. They will be perfect life-giving foods for us to taste God in the “Garden of Eden" today.

This study is a Korean Christian ethical interpretation of Life-giving and Peace-making movements in Daegu-Gyoungbuk area, especially focused on 1900s to 1940s. It is very important for me to build Life-giving and Peace-making theology and ethics reflected upon praxis in Korean context. First of all, I deal with anti-Life and anti-Peace history under Japanese colonialism. Then I try to find out four Christians; Mr. Sang Don Suh, Rev. Man Jib Lee, Rev. Moon Sik Choi and Rev. Jae Gi Yoo who have been practiced their own specific Life-giving and peace-making faith and life toward society and national liberation and church as well. As a result of this study, it becomes evident that some of Christian leaders of Daegu and Gyoungbuk area had been practiced Life-giving and Peace-making faith and life. They also had been influenced to so many people socioeconomically, sociopolitically and agriculturally even though they were Christians or non-Christians. I, therefore, conclude that we have to learn and practice their costly discipleship, dig out their beautiful Life-giving and Peace-making faith and life and then connect today's Daegu and Gyoungbuk Churches towoard social harmony, national reunification and global Life and Peace in fullness.

사도행전에 나타난 초기 기독교 공동체의 비빔의 밥상

This study is a Christian social ethical reflection of the early Christian community in Acts 2:42-47. It is very important for us to find out early Christian Community with Holy Spirit. There are so many various and different believers in Acts but they joined with other believers. They preserved in the apostles’ teaching; in fellowship; in the breaking of bread; and in prayer with Holy Spirit. It’s very similar theory of Korean bibimbap. According to Korean bibimbap, firstly there is boiled rice in the bottom of vessel; secondly cooked bracken from mountain, bean sprouts and cucumber from earth and beef from farm; thirdly dried seaweed and tangle from sea; fourthly egg from sky; fifthly, people have to add hot pepper paste and then mix every foods with sesame oil. Every food was mixed slowly, harmonized and then have totally different great tasting than ever met before. Finally, it becomes “bibimbap” that Korean people like the most among all foods. There are all foods in one vessel from sky, mountain, earth and sea. Therefore, it is small universe with peace and harmony in one vessel. The early Church community with Holy Spirit in fullness has four spiritual foods such as preserving in the apostles’ teaching; in fellowship; in the breaking of bread; and in prayer with Holy Spirit. These spiritual foods were mixed, harmonized and became holy oneness towards Reign of God. It’s why they sold their property and their belongings and distributed them to all. It’s totally different way of Christian beautiful life. It’s the same theory comparison to bibimbap theory in Korea. In conclusion, the early Christian community suggests for us to have a holy unity in diversity and sharing economy and then new way of life in multicultural and crosscultural society and global world for the God’s Reign.
