A novel antifuse has been developed for field programmable gate arrays (FPGA`s) as a voltage programmable link with Al/BaTiO₃/SiO₂/TiW-silicide. The proper program voltage can be obtained by adjusting the deposition thickness of BaTiO₃ film. When a negative voltage was applied at bottom TiW-silicide electrode of the antifuse, based on BaTiO₃(120Å)/SiO₂(120Å), the program voltage was about 14.4V and on-resistances were ranged between 40 and 50Ω. The current-voltage characteristics of antifuses are consistent with a Frenkel-Poole conduction model. However, there are some deviations depending on bias polarity that are probably due to the difference in the interface properties between Al/BaTiO₃ and TiW-silicide/SiO₂.

본 연구는 조선족과 한족(漢族)으로 대별되는 중국인 이주자 집단이 어떤 이유와 과정을 거쳐 서울시 내로 이주하여 정착하고 있는지를 문헌자료와 통계 분석, 현지조사와 인터뷰를 통해 사회-공간적인 관점에서 살펴보고 있다. 같은 중국 국적인 이 두 집단의 상이성 지수를 산출해 보았을 때, 조선족 집단은 전통적인 엔클레이브인 서울 서남부 지역과 자양동 지역에서 가장 높게 나타나고 있는 반면 한족 집단은 서울 강북의 주요대학 주변지역과 조선족 밀집지역인 서남부지역에서 가장 높게 나타나고 있다. 이들의 거주공간이 이렇게 분리되거나 중첩되어 나타나는 것은 두 집단의 계층, 이주 목적, 체류자격 등의 차이에 따른 결과이다. 흔히 조선족 엔클레이브로 알려진 서울 서남부 지역과 자양동 일대 지역은 이 두 집단 간 경제적, 심리적 필요성에 의해 협력과 공생의 기본적인 관계가 형성되어 있으나, 기원지의 민족간 관계와 민족문화의 상이성에 기인한 미묘한 갈등도 내재되어 있는 독특한 이주자 엔클레이브를 형성하고 있다. This study investigates the reasons and processes of Chinese migrants` movement and settlement into the City of Seoul from the socio-spatial perspective utilizing the research materials such as literature, population census, field survey, and interviews. Two Chinese migrants groups of Korean-Chinese and Han-Chinese have their major residential districts separated at various spots and overlapped at the southwestern part of Seoul. This residential separation and overlapping are formed under the influence of social classes, aims of migration, documents of employment and staying. The Josunjok Town has two Chinese ethnic groups keeping cooperative and symbiotic relationships in terms of economic employment and psychological familiarity. And also the groups sometimes show disharmony and conflicts in the course of active agents` role for the place-making of their own urban immigrants enclave.

지구-지역화가 광범위하게 진행되고 정보와 교통의 혁신이 인간 생활의 변화를 촉발하면서 국경을 뛰어넘는 이주가 전세계적으로 더욱 빠른 속도로 증가하고 있으며, 전례없는 새로운 이주 패턴이 출현하고 있다. 특히 국제 이주가 보여주고 있는 질적인 측면의 변화에 주목해 볼 필요가 있는데, 이런 새로운 변화에 적응하고 편승한 쌍방향적 교류와 이동이 활발히 진행되면서 소위 트랜스이주라는 개념이 최근 이주 연구에서 주조되어 큰 주목을 받고 있다. 글로벌시대의 트랜스이주를 실천하는 이주자들은 자신의 사회적 관계를 하나의 로컬에만 국한시키는 것이 아니라 다수의 로컬에 걸쳐서 전개시켜 나간다. 본 연구에서는 이주자가 새로운 정착지에서 어떤 사회적 관계를 구축하여 로컬에 착근시키고 있는지를 조선족 이주자들이 정착한 서울 자양동 중국음식문화거리를 통해 밝히고 있으며, 더 나아가 그러한 사회적 관계가 로컬리티의 변화에 어떤 영향을 끼치고 있는지를 탐구하고 있다. 본 연구의 결과에 의하면, 트랜스 이주자는 단순히 정착지에 적응하려 애쓰는 수동적 객체가 아니라 정착지의 특성을 변화시키는 능동적 주체이다. 서울 자양동 중국음식문화거리의 조선족은 자신들의 사회적 관계를 통해 로컬에서 주류사회의 차별에 저항하고 있으며, 조선족 네트워크에 의한 사회적 자본을 형성하면서 사회적 관계를 확대해 나가고 있다. 주류사회의 입장에서는, 조선족 이주자의 유입이 일부에게는 긍정적으로 작용하고 일부에게는 부정적으로 작용하면서, 결국 이주자와 주류사회 간의 독특한 사회적 관계의 형성으로 이어지게 된다. 이제 로컬에 공존하는 다양한 주체들은 그들의 사회적 관계를 로컬에 착근시키면서 지속적인 로컬리티의 변화를 이끌어가게 되는 것이다. Through the advance of globalization-localization and the innovation of information and transportation, migration which transcends national borders has rapidly increased, and new patterns of migration have arisen in recent years. Especially, we need to attend the qualitative changes in the international migration, as this change derives on the attention on, so called, trans-migration which focuses on multi-lateral communication and mobility by migrants. Migrants, who practice trans-migration in the global age, are not inclined to limit their social relations into one local, but extend into diverse locals in the world. This research reveals the local embeddedness of the migrants` social relations in the new settlement and also its effects on the changes of locality through Korean-Chinese in the Chinese Food Culture Street in Jayang Dong of Seoul. As the result of this study, trans-migrants` are not simply adapting into the destination`s social environment, but an active actor who makes local characteristics. Korean-Chinese people in the Chinese Food Culture Street make their social network to cope with the discrimination by the mainstream society. The Korean-Chinese networks form the social capital in the Chinese Food Culture Street, which perform to extend social relations among them. In the view of core society, the influx of migrants bring about positive and negative effects, deriving distinct social relations in the local. Various subjects co-existing in the local are embedding their social relations into the local, deriving the changes of locality.

N/A Objectives: Gastric dysplasia is defined as a lesion characterized by cellular atypia, abnormal differentiation and disorganized architecture without showing malignant nature in histology. Even though it was known as a precursor of gastric cancer, there were few studies in clinical and biological aspect in practice. Because the early detection of gastric cancer is very important, we have evaluated the risk of gastric carcinoma following the gastric dysplasia in prevention of gastric cancer. Methods: The authors evaluated the clinical and histological findings of 27 cases of gastric dysplasia for at least 3-12 months among 38 cases of gastric dysplasia and which confirmed from January 1992 to June 1994. Results: The sex distribution of 38 cases with gastric dysplasia was that men were 29 cases and women were 9 cases. The Highest incidence was above 6th decades(30cases) in age. Twenty seven cases of gastric dysplasia could be followed prospectively. Each histologic findings were as follow, mild dysplasia 12 cases, moderate dysplasia 7 cases and severe dysplasia 8 cases respectively. The endoscopic findings showed erosion 6 cases(16%), flat lesion 8 cases(21%), ulcer 10 cases(26%), polypoid lesion 14 cases(37%) respectively, The evolution of dysplasia was regression 4 cases, persistence 4 cases, progression 3 cases, cancer 1 case(9%) in mild dysplasia and regression 2 cases, persistence 2 cases, progression 1 case, cancer 2 cases(29%) in moderate dysplasia. In eight severe dysplasia, 1 case of regression, 3 cases of persistence and 4 cases of cancer(50%) were developed. Polypectomy was performed in 12 cases and 1 case was regressed from severe dysplasia after mucosal resection. In 27 cases of gastric epithelial dysplasia, gastric cancers were developed in 7 cases(26%) and early gastric cancers were 4 cases(57%) among them and the most common lesion was ulcer(5 cases). Conclusion: Gastric dysplasia should be strictly followed up with repeated endoscopic examination as well as treated the adequate endoscopic procedure for the prevention of progression or the risk of developing cancer.

This paper investigates the pattern of Korean Chinese migration out of the Yanbian region particularly focusing on the last three decades, and also the recent change of urban commercial landscape in Yanbian and the dwellers` life culture. The concept of translocality is used as the basis of analytic framework, so as to get out of the limitation of methodological (trans-)nationalism in the research on the global migration and its effect on the life cultures and places. With the formation of the Korean Chinese world-wide social network covering the whole regions of China and 88 foreign countries, the economic and cultural ties of the people between origin and destinations have been more intensified, which cause a great change in urban life and commercial landscape of the City of Yanji, the capital city of Yanbian Korean Chinese Autonomous Prefecture. Going along with the spread of global capitalism, the globally diffused Korean Chinese have kept in touch with each other binding the origin and destinations, and thus the Autonomous Prefecture and the Yanji City have been rapidly reconstructed by the overseas influences crossing over the porous boundary. The cultural, economic, and social interaction through the remittance by Korean Chinese out-migrants has played a critical effect on the urban social change of the City of Yenju.

Hereditary hemorrhagic telangiectasia (HHT, also called Osler-Weber-Rendu Disease) is a rare systemic fibrovascular dysplasia characterized by recurrent epistaxis, cutaneous telangiectasia, and visceral arteriovenous malformations (AVMs). HHT is an autosomal dominant disease with a prevalence of 1 in 5,000∼8,000. Recurrent epistaxis is often the first and most common manifestation, and about 30% of patients reveal pulmonary AVM. Presently, we report a familial case of HHT. A 61-year-old male with asymptomatic multiple pulmonary AVMs was successfully treated with embolization. His older brother who presented with recurrent epistaxis and multiple telangiectasias was treated with laser ablation. Their pedigree revealed a family history of recurrent epistaxis.

Objectives:There are some evidences that patients with bipolar depression experience more stressful life events than patients with unipolar depression do. However, there is lack of evidence that bipolarity in depressive patients is associated with more frequent and severe stressful life events. The current study is aimed to compare life events and perceived stress according to the Bipolar Spectrum Diagnostic Scale(BSDS) results in depressive patients. Methods:A total of 102 patients who have experienced major depressive episodes were recruited. Two groups with or without positive screening of Bipolar Spectrum Diagnostic Scale(BSDS) were divided. Stress-related factors were measured by the Life Experiences Survey(LES) and Perceived Stress Scale(PSS). Results:Patients with depressive disorders who screened positive on the BSDS showed more life events(p=.006) and higher impact of life events(p=.005) checked on the LES, and higher score on the PSS negative perception subscale(p=.010) than those who screened negative on the BSDS did. After the adjustment of Beck Depression Inventory(BDI), depressive patients with BSDS(+) experienced more life events(p=.019) and higher impact of life events(p=.029) than those with BSDS(-). However, the difference of PSS negative perception subscale between two groups disappeared after adjusting the effects of depressive symptoms. Conclusion:These results suggest that depressive patients with positive screening of BSDS may response to life events in negative ways and feel more stressful. The positive screening of BSDS in depressive patients can affect their trajectories of depression. Further, large scale and prospective studies are needed to clarify these relationships between bipolar spectrum disorder and stress.
