Two types of polyimide/silica composite films were prepared using sol-gel method through hydrolysis and polycondensation of tetraethoxsilane(TEOS) with the polyamic acid(PAA) and end-capped PAA solution. Sample were characterized by the means of differential thermogravimetry, X-ray diffractometry, scanning electron microscopy, universal test, impedance analyzer, chemical resistance test, etc. All of the PAA/silanol solutions heat-treated at 300℃ for 6h were transformed to polyimide/silica composites. It has been demonstrated that the properties of polyimide/silica composites were affected by the amount of silica addition and the bond type existed between polyimide and silica.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

정성일의 <오아시스> 비판에 투영된 관점의 가능성과 한계 - 정성일 영화비평에 대한 일고찰 -

박우성 ( Park Woo-sung ),정수완 ( Jung Su-wan ) 국제어문학회 2015 국제어문 Vol.0 No.67

본 연구는 영화비평가 정성일이 <오아시스>(이창동, 2002)에 대해서 쓴 비평문「판타지, 기만적인 환영술」을 비판적으로 분석한다. 그간 한국영화계에서 영화비평은 독립적인 분과로 논의되지 못했다. 산적하는 영화들 안에서 영화적 가치를 발굴해 정리하고 새로운 영화 언어를 대중 언어로 번역하는 것이 영화비평의 역할이라 했을 때 이는 문제가 있다. 영화비평에 대한 그간의 접근은 한국영화사의 맥락에서 특정 영화비평집단을 세대론적으로 조망하거나 특정 개인의 비평 세계를 전기적 관점에서 서술한 것에 머문 한계가 있다. 정성일은 1990년대 한국영화비평의 전성기를 주도했던 한국의 대표적인 영화비평가이다. 호불호가 갈리지만 그의 글은 대중들 사이에서 영화비평이라는 개념이 성립되는 과정에 주요한 이미지를 제공했다. 특히 본 연구가 다루는 정성일의<오아시스> 비판은 논쟁 참여를 전제해 작성된 덕분에 비평담론 자체가 중심에 서있고 무엇보다 정성일의 영화에 대한 태도가 여타의 글에 비해 명확하게 드러나는 특징이 있다. 더구나 그 논쟁은 영화의 윤리, 완성도, 자의식 등을 두고 벌어진 영화비평계 내부의 마지막 논쟁이라는 영화비평사적 의의도 있다. 나아가 영화 한편에 대한 긴 글이기 때문에 한국의 대표적 비평가가 영화를 비평하는 구체적 실천 양상이 현장감 있게 녹아 있기도 하다. 영화를 종교처럼 대한다는 비판이 존재하지만 정성일 영화비평의 경쟁력은 숏의 배치, 장르 문법, 카메라 시선과 같은 영화의 자의식을 정밀하게 분석하는 것에서 나온다. 영화란 무엇인가와 같은 근본적인 질문에 기반을 둔 이런 태도는 영화를 여타의 학문에 종속시킨 종래의 비평 태도와 차별되며 영화를 진지하게 바라보는 태도를 대중화시킨 의의가 있다. 하지만 그것만큼의 오류도 발견된다. <오아시스>를 비판할 때 투영되는 정성일의 관점의 가능성과 한계를 구체적으로 밝힘으로써 한국영화비평의 전성기를 주도했던 한 영화비평가의 개성적 세계관을 비판적으로 조망하는 것이 본 연구의 목적이다. 독립적인 분과로 인식되기는커녕 죽음까지 운운되는 영화비평의 위기 시대에 한국의 대표적 영화비평가의 세계관이 상징적으로 녹아 있는 글을 정밀하게 분석하는 것은 그것 자체로 의미 있다. This study analyzes the critique “Fantasy, deceptive hallucination” which sung-il jung wrote about < Oasis >(Changdong Lee 2002). Film critique has not been recognized and discussed as an independent field in the Korean film industry so far. It can be problematic if the role of film criticism is to get the cinematic values arranged among the pile of films and to translate new cinematographic language into the public language. The approach to the film critique to this point has limitation that in the context of Korean film industry, it viewed certain group of film critics in the perspective of theory of generation and it described certain person`s world of criticism in a biographical way. sung-il Jung is one of the representative film critics in Korea who lead the golden age of Korean film criticism in the 1990s. His writings provided important image in the process of establishing the concept of film critique among the public, even though they are controversial. The Jung`s criticisms this study exclusively deals with are based on the premise of argumentative participation, so the discourse is central and fundamental, and it brings out the cinematic view of Jung precisely compared to the other writings and articles, which is the advantages of this study. Moreover, the argument has significance in the field of film criticism for being the last dispute inside the field of film critique over the morals, degree of completion, and the consciousness of identity. Above and beyond, because this paper is a long writing about a movie, it contains detailed and vivid practical aspect which the representative critic of Korea criticizes the movie. Although there are criticisms of discussing movies like a form of religion, sung-il Jung`s film critique is competitive for detailed and precise analyze of films` sense of identity such as plot of shots, code of genre, and the eyes of cameras. This attitude based on the fundamental questions such as what is film is considered significant for popularizing and promoting earnest attitude toward movies, and is differentiated with the traditional attitudes of criticism which are to subordinate films in the other fields of study. However, due to being so, some errors are discovered. The purpose of this study is to critically outlook a distinctive world view of a film critic who enjoyed the film critique`s prime by concretely describing its possibilities and limitations through revealing Jung`s point of view which is his prerequisite for watching movies. The work of precise analyzing of one of the Korean representative film critics` writings which contains symbolic world view is significant and meaningful by itself in the time of the film criticisms` crisis when the idea of the demise of film criticism is being mentioned, let alone its separation as the independent field.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

The purpose of this study are to develop a SDSS (Spatial Decision Support System) that can incorporate diverse opinions of stakeholders related the designation of protected areas (PA), and to employ the model for the readjustment of the boundary line of the Jirisan National Park of Korea. The SDSS would lead to more rational and less controversial decision-making during the expansion or removal of PA in Korea. Research methods are as follows. Firstly, to select evaluation criteria for SDSS for PA designation by using expert interview and literature survey. Secondly, to measure their preferences on the designation of additional PA or the removal of a part of PA based on the opinions of various stakeholders such as local residents, environmental groups, or public officials. Thirdly, to produce conservation priority maps based on a multi-criteria decision making technique. The SDSS would be used to rational decision making for the expansion of PA or the release of a certain part of PA by reflecting diverse preferences on biodiversity conservation and economic interest of residents. The visualization of conservation priority maps would also increase the efficiency of such decision making processes. The evaluation criteria for the expansion of PA for biodiversity conservation includes vegetation conservation value, wildlife conservation value, and the habitats of key species. The evaluation criteria for the removal of PA includes the proximity to roads and the boundary of PA, land use types, and conservation zoning of the PA. Preference weights are based on data collected from the Jirisan National Park. Both the conservation priority and removal priority maps are based on land parcels so that property rights of all parcels would be correctly represented.

Purpose: To compare the surgical outcomes of functional equator-considering and Parks’ methods in infantile esotropia and partially accommodative esotropia. Methods: The medical records of 96 patients with infantile esotropia and partially accommodative esotropia who underwent bilateral medial rectus muscle recession by functional equator-considering and Parks’ methods were reviewed retrospectively. The surgery success rate at 1 month, 3 months, 6 months and 12 months was compared by the deviation angle measurement. Results: Overall success rates were not statistically different between the 2 groups. Additionally, there were no differences in surgical success rate of functional equator-considering and Parks’ methods in infantile esotropia and partially accommodative esotropia. When the patients were divided into 2 groups based on 40 PD, no significant difference in success rate between the 2 groups was observed. When patients were divided into 2 groups based on 22 mm of axial length, there was no statistical difference observed. Postoperative overcorrection was 2 (4%) in the functional equator group and 3 (6.5%) in Parks’ method group and postoperative undercorrection was 9 (18%, 19.6%) in each group. The incidence of undercorrection in the Parks’ method group was significantly higher in the greater than 22 mm axial length group (7, 35.0%) than in the less than 22 mm group (2, 7.7%) (p = 0.029). Conclusions: There was no statistically significant difference in surgical success rate between the functional equator and Parks’ methods in infantile esotropia and partially accommodative esotropia.

국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

The method of manipulation by striking a part and letting it slide until it comes to rest, has been very little studied. However, the manipulation method is not uncommon in our daily lives. We analyze the dynamic behavior of a rigid polygonal part being striked and sliding on a horizontal surface under the action of friction. There are two parts to this problem; one is the impact problem, and the other is the sliding problem. We characterize the impact and sliding dynamics with friction for polygonal parts, and present the possibility of reverse calculation for motion planning of striking operations. Using a high speed video camera. the computer simulation results are experimentally verified. Simulation and experimental results agree well.
