Background: Postpneumonectomy empyema (PPE) due to bronchopleural fistula (BPF) can be a surgical challenge for surgeons. We analyzed the follow-up outcomes after performing omentopexy and thoracoplasty for the treatment of PPE with BPF after pneumonectomy. Material and Mehod: Between December 1991 and January 2006, 9 patients underwent BPF closure using an omental pedicled flap for the treatment of PPE with BPF after pneumonectomy. There were 7 males and 2 females (mean age: $45.9{\pm}9$ years). The patients were followed up for a mean of 58 months (median: 28 months, range: $6{\sim}169$). When we performed omentopexy, the surgical procedures for empyema were thoracoplasy for 8 patients and the Clagett procedure for 1 patient. Thoracoplasty was performed for the latter patient due to recurrence of empyema, Result: For the 8 patients who were treated by omentopexy and thoracoplasty, there was 1 operation-related death due to sepsis. During follow up, 1 patient, who was treated by omentopexy and a Clagett procedure, died of acute hepatitis 40 months postoperatively. The early mortality was 11.1% (8/9). Of the 8 patients, including the 1 late death patient, successful closure of the BPF were achieved in all patients (8/9) and the empyema was cured in 7 patients (7/8). Conclusion: The BPF closure using an omental pedicled flap was an effective method for treating PPE with BPF due to 75-destroyed lung, and thoracoplasty with simultaneous omentopexy was effective and safe for removing dead space if the patient was young and in a good general condition.

Purpose: FDG uptake on positron omission tomography (PET) has been considered a prognostic indicator in non-small cell lung cancer (NSCLC). The aim of this study was to assess the clinical significance of maximum value of SUV (maxSUV) in recurrence prediction in patients with surgically resected NSCLC. Materials & methods: NSCLC patients (n=42, F:M =14:28, age $62.3{\pm}12.3$ y) who underwent curative resection after FDG-PET were enrolled. Twenty-nine patients had pathologic stage 1, and 13 had pathologic stage II. Thirty-one patients were additionally treated with adjuvant oral chemotherapy. MaxSUVs of primary tumors were analyzed for correlation with tumor recurrence and compared with pathologic or clinical prognostic indicators. The median follow-up duration was 16 mo (range, 3-26 mo). Results: Ten (23.8%) of the 42 patients experienced recurrence during a median follow-up of 7.5 mo (range, 3-13 mo). Univariate analysis revealed that disease-free survival (DFS) was significantly correlated with maxSUV (<7 vs. $\geq7$, p=0.006), tumor size (<3 cm vs. $\geq3$ cm, p=0.024), and tumor tell differentiation (well/moderate vs. poor, p=0.044). However, multivariate Cox proportional analysis identified maxSUV as the single determinant for DFS (p=0.014). Patients with a maxSUV of $\geq7$(n=10) had a significantly lower 1-year DFS rate (50.0%) than those with a maxSUV of <7 (n=32, 87.5%). Conclusion: MaxSUV is a significant independent predictor for recurrence in surgically resected NSCLC. FDG uptake can be added to other well-known factors in prognosis prediction of NSCLC.

To elucidate the novel biological function of Korean traditional vinegars, crude polysaccharides were isolated from vinegars manufactured at home and abroad, and their chemical properties and immuno-stimulating activities were examined. Three kinds of polysaccharides from Korean brown rice vinegar (KBV-0), Japanese brown rice vinegar (JBV-0) and Korean persimmon vinegar (KPV-0) showed higher immuno-stimulating activity. Component sugar analysis indicated that KBV-0 and JBV-0 mainly consisted of mannan, whereas KPV-0 existed as pectic materials. Three polysaccharides did not show any cytotoxicity to RAW 264.7 cell, whereas RAW 264.7 cells stimulated with KBV-0, JBV-0 and KPV-0 showed enhanced production of various cytokines such as IL-6, IL-12 and TNF-${\alpha}$ in dose-dependent manners. However, the activity of KPV-0 was more potent than that of KBV-0 and JBV-0. Also, only KPV-0 augmented FcR II expression related with phagocytosis of macrophages. The results suggest among the tested vinegars, that the Korean persimmon vinegar has the most potent immune-stimulating activity, and it could possibly serve as industrial applications as functional materials.

The IHO developed the S-100 standard for Digital Hydrographic Data in order to assist the proper and efficient use of hydrographic data and information for the safety of navigation and the protection of marine environment. The former model, S-57, was considered outdated to be utilized as the basis for the next-generation Electronic Chart(ENC) product specification. The key feature of the S-100 standard is the use of Registry and its components, Registers. This online-based Registry provides a universal standard that can be implemented in the actual performance of the navigation system with convenience. In the current situation, the only registry is owned by the IHO and it is available to domain experts. However, since S-100 is an international standard operated by an international organization, the process of the changes and updates of the data requires time before immediate implementation when demanded. Therefore, regarding the safety of navigation of the domestic users and mariners, a separate domestic registry is necessary to develop a domestic Information Registry. This study specifically aims to build a Registry based on IHO published S-99 through designing an adequate website dedicated for its purpose to provide collection of definitions and hydrographic data.

This paper analyzes Korean aesthetic characteristics of Korean independent animation, which is closely related to artistic and social characteristics, by searching Korean independent animation image for the winner of "Indie AniFest", the only independent animation film festival in Korea. And social communication methods. There are three ways in which Korean Independence Animation shows the way of speaking through award-winning works. The first is a method of expressing feelings, impulses, and desires in a formative way, and a direct and sensuous image as in sign language or sound. In the second method of speaking differently with images, in the third method, It makes the voice of the fringe through the real world of the story sound as a story of reality. Animation is a medium that 'originalizes and communicates meaning' as an image, and has implemented and constructed a new way of speaking, which is different from existing social voices. Nevertheless, it is not easy to find a research that approaches animation from the viewpoint of social and political speech through images. Therefore, this paper is necessary for the balanced development of animation. In addition, this study can contribute to re - examining Korean independent animation from an academic point of view and to discover and evaluate fair value from a wider perspective.

Hong-sii Tokso-rok (홍씨독서록 or Hong's Annotated Bibliography of Korean and Chinise Book) is the only work on the history of Korean bibliographies that has the introductory notes to each class, that is description of the origin of subject fields, transition, and characteristics at the beginning of each class. This paper is aimed to examine the outline of the introductory description of class, to analyze the Four Category Classification System(사부분류법) devised by Hong Sok-chu, and to explain how the classes of Four Category Classification are set and ordered. This paper shows several characteristics in the idea of Hong's classification system. There characteristics were discovered by analyzing the content of each introduction of classes. The characteristics ale as follows First, classes are organize and arranged from the substantial problem to nonsubstantial ones. In other words, the greater the distance of the class from the substantial problem of Confucianism, the farther the order of the class will be found from the substantial problem. The order of classes is set by how the class is closed to the substantial problem in the same hierarchy. This principle is strictly applied to the Hong's classification system. Second, on the basis of democratic thought, he del·eloped the classification system. In other words, when he set up the priority of classes, he put emphasis on the democratism as a guideline. The organization of classes belong to the catagories of history (Sa-bu, 사부) and philosophy(Cha-bu, 자부) showed the application of this principle. Conclusively, this paper found that Hong did not randomly arrange the class older, but he set the class order with objective reasons and logic when he set the class order of arrangement.

It was characterized the hexane biodegradation and mineralization using a hexane-degrading consortium, and analyzed its bacterial community structure by 16S rDNA PCR-DGGE (denaturing gradient gel electrophoresis). The specific growth rate (${\mu}_{max}$) of the hexane-degrading consortium was 0.2 $h^{-1}$ in mineral salt medium supplemented with hexane as a sole carbon source. The maximum degradation rate ($V_{max}$) and saturation constant ($K_{s}$) of hexane of the consortium are 460 ${\mu}mol{\cdot}g-DCW^{-1}{\cdot}h^{-1}$ and 25.87 mM, respectively. In addition, this consortium could mineralize $49.1{\%}$ of $^{14}C$-hexane to $^{14}CO_2$, and $43.6{\%}$ of $^{14}C$-hexane) was used for the growth of biomass. The clones isolated from the DGGE bands were closely related to the bacteria which were capable of degrading pollutants such as oil, biphenyl, PCE, and waste gases. The hexane-degrading consortium obtained in this study can be applied for the biological treatment of hexane.

In this study, we investigated antimicrobial and cytotoxicity effects of Gelidium amansii L., which using methanol, dichloromethane and ethanol were extracted and fractionated into four different types : methanol (GAMM), hexane (GAMH), butanol (GAME) and aqueous (GAMA). The antimicrobial activity was increased in proportion to its concentration by the paper disc method. Among the solvent fractions, The methanol partition layer (GAMM) showed the strongest antimicrobial activities and cytotoxic effects on all cancer cell lines. We also observed quinone reductase (QR) induced effects in all fraction layers of GA on HepG2 cells. The QR induced effects of GAMM on HepG2 cells at $40{\mu}g/mL$ concentration indicated 2.5 with a control value of 1.0.

이제까지 부활된 정기시장인 원주시 쌍다리 풍물시장의 현황을 관찰, 면담, 설문지를 통하여 많은 문제점과 나름대로의 대안을 살펴보았다. 여러 가지 문제해결의 요소들이 복잡하게 얽혀 있는 쌍다리 풍물시장의 활성화 방안을 살펴보기에 앞서 풍물시장의 이해 관계자들을 살펴보기로 하자. 쌍다리 풍물시장의 이해관계자는 크게 4가지 부류로 나눌 수 있다. 첫째로, 상설상인들을 들 수 있다. 이들은 거리에서 노점상을 했던 도시빈민들이 대부분이며, 설문지에서 나타나듯이 낮은 학력, 소자본 그리고 노령인구층과 여자의 비율이 높다. 이들은 두 가지에 큰 관심을 가지고 있는데, 매장의 소유권과 5일장이다. 매장의 소유권은 이들에게 있어서 큰 희망이며, 5일 장날의 매상은 평소의 $5{\sim}6$배를 웃돌고 있기 때문이다. 또한 풍물시장 번영회라는 그들의 이익을 대변할 수 있는 단체를 구성하고 있으며 이러한 풍물시장 번영회는 상설상인들의 이익을 도모할 수 있는 여러 노력들을 하고 있다. 둘째로는 이동상인들을 들 수 있다. 이들은 장터를 떠돌아 다니며 상행위를 하는 부류로서 상설상인에 비해 상대적으로 고학력과 장년층이 많다. 이들은 5일장의 성쇄와 깊은 관련이 있으나, 5일장이 열리는 상설시장의 발전에는 아무런 흥미가 없다. 즉, 이동상인이 많이 모여드는 곳은 5일장이 크게 번창하지만, 그곳의 장이 패할 기미가 보이면 미련 없이 떠난다. 따라서 보다 많은 이동상인의 유치는 도시 5일장의 성쇄와 깊은 관련이 있다. 셋째로는 시당국을 들 수 있다. 시당국에 의해서 쌍다리 풍물시장은 노점단속에 반발하는 노점상들에 대응하기 위하여 생겨났으며, 5일장 역시 시당국에 의해서 부활된 것이다. 그러나 단기적인 측면만을 고려한 듯한 인상을 풍기는 쌍다리 풍물시장에 대한 행정은 대단히 아쉬운 부분이며 앞으로도 여러 가지 구조적인 문제점의 해결은 시당국에 달려있다고 해도 과언이 아니다. 즉, 풍물시장에 관련된 이해관계자들 중 유일하게 조직과 행정력을 가지고 문제해결을 할 수 있는 주체인 것이다. 넷째로는 풍물시장을 이용하는 소비자를 들 수 있다. 이들은 주로 원주에 살고 있는 사람들이 대다수이며 쌍다리 풍물시장을 이용하는 이유는 저렴한 가격에도 원인이 있지만 민족의 정서가 어려있는 시골장터에 대한 향수 역시 큰 원인으로 꼽을 수 있다. 이러한 점은 소비자 설문에서 구경거리를 위하여 장에 오는 소비자의 비율이 생각 외로 높게 나타남으로써 알 수 있다. 미국을 위시한 선진국들의 시장개방 압력과 우루과이라운드의 등장으로 우리나라는 경제, 사회문화적인 위기에 봉착해 있다. 1960년대 이후 계속되어 온 경제 제일주의 정책으로 우리 민족의 정서와 문화를 보존하는 일에 등한시하여 왔다. 이 때문에 우리 민족 고유의 뿌리를 점차 잃어가고 있다. 이러한 시점에서 도시노점상을 정리하기 위한 목적으로 정부에서 도시 5일장을 개장한 것은 역사의 아이러니라 아니할 수 없다. 이렇게 정부주도로 개장된 5일장이 운영되어 온 지 2년이 되어가고 있다. 개장 초기에는 시에서의 지원도 적극적이고 소비자들의 호응도 좋았으나, 최근에 들어 활성화의 속도가 둔화되면서 도시 5일장의 개념을 재정립할 필요성이 제기되고 있다. 정부의 주도로 시작된 5일장이므로 정부의 적극적인 추진하에 풍물시장 번영회와 활성화 방안을 모색해야 한다. 쌍다리 풍물시장의 5일장을 활성화하기 위하여 도시 5일장의 개념을 ${\ulcorner}$국민들의 생활수준이 향상되고 여가를 즐길 수 있는 여건이 형성되고 있으므로 전통문화(향토문화)를 유지하고 시민들의 정서함양에 기여할 수 있는 여가공간 조성${\lrcorner}$으로 규정해야 한다. 이러한 개념 하에 5일장의 주체를 명확히 하기 위해 시청 지역경제과를 중심으로 지자제의 실시에 발맞춰 지역특색에 맞게 5일장을 활성화하기 위한 전학을 수립해야 한다. 서울대형백화점인 롯데 슈퍼백화점이 송파 큰장터나 그랜드 백화점의 향토물산전의 성공은 도시 5일장의 활성화 가능성을 미루어 짐작할 수 있다.

Of safety check regulation, 'Construction Technology Promotion Act' and 'Special Act on the Safety Control of Public Structures' contain provisions about the content of safety in construction works and the items of safety checks in the maintenance aspect and thus contribute to accident prevention in the construction industry. Of the regulations responsible for the practical safety of workers, the safety check regulation of Ministry of Employment and Labor demand for safety check from the start of construction based on an agreement with a concerned agency to the completion of construction solely based on 'Guidance Standards for the Specialized Disaster Prevention Instruction in Article 32 of Occupational Safety and Health Act' and 'Appropriation and Usage Standards of Safety and Health Management Costs in the Construction Industry'. There is, however, a huge gap, as well, in them according to client agencies. In small construction sites ordered by a private organization, checks are done formally with no detailed regulations. As a result, the costs of checks continue to drop with only the contract kept intact. This study examined the forms of safety checks practically done in the Jeju region, distinguished and compared them by the construction costs, calculated proper costs based on each construction act, and further proposed improvement measures for the detailed regulations.
