Actinomycosis is an uncommon chronic suppurative disease characterized by multiple abscess, draining sinuses, abundant granulation, and dense fibrous tissue, caused by the actinomyces organisms. It occurs in three major sites: cervicofacial, abdominal, and thoracic. The abdomen is the second most common involved site in previous studies, and there are three ways this organism can affect the gastrointestinal tract: through a blood-borne infection, by swallowing, or by proliferation at a more distal intestinal area. Abdominal actinomycosis is an unusual disease but remains an important differential diagnosis in patients with abdominal mass. Obtaining the diagnosis is difficult and rarely made preoperatively, but provide the key to its management. Medical therapy is effetive in eradicating the disease; however, because of the large amount of reactive fibrosis formed by the infection, it requires long-term therapy. Surgical treatment may be essential in many cases, primarily when malignancy cannot be excluded or if extensive necrotic tissue exists. There are a few description for actinomycosis involving omentum. We report a case of patient with omental actinomycosis, suspected to have a malignancy requiring an exploratory laparotomy with resection.

The substrate removal rate in a biofilm was investigated by the measurement of substrate concentration in an inverse fluidized bed operated batchwisely. When the biofilm thickness was below 60㎛, the overall reaction rate was found as first order but it turned out to zero order at the thickness of above 60㎛. The reaction rate constant and the effective diffusivity could be calculated by using a mass balance and a diffusion model in the biofilm and a typical effective diffusivity of zero and first order reaction were calculated as 5.49×??㎠/s and 2.3×??㎠/s, respectively. In the region of zero order reaction, the effect of diffusion on the effectiveness factor increased with increasing biofilm thickness. Therefore in the zero order region, the diffusion step controlled the system while the reaction step controlled in the first order region.

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

한국임학회지 (1962년의 1호~2002년의 91권 6호)에 게재된 특용자원식물 관련 논문에서 식·음용식물, 약용식물, 사료식물, 조경식물, 섬유식물, 산업용식물 및 밀원식물로 분류하고 그 내용에 따라 입지환경, 생태, 생리, 번식, 조림(또는 무육, 재배), 유전·육종, 분류(또는 식별), 병·충해와 방제, 동물피해와 방제, 성분분석, 식생정보, 생물공학, 경영·경제 및 총설로 나누었다. 총 1,434편의 발표 논문 중 유용식물자원을 대상으로 한 논문은 27.6%를 차지하는 396편이었고, 내용은 식생정보 60편(15.2%), 생리 56편(14.1%), 유전·육종 56편(14.1%), 번식 53편(13.4%) 및 생태 37편(9.3%)이었다. 조림(무육·재배)은 11편(2.8%)으로 특용자원식물의 규모경영이 이루어지지 않고 있음을 시사하고 있으며, 이것은 경영·경제 분야가 6편(1.5%)인 것과 맥을 같이 하고 있었다. 연구대상 식물은 잣나무(42편), 아까시나무(23편), 밤나무(14편) 및 은행나무(14편) 순으로 높았고, 이 식물들과 관련한 연구내용은 번식, 생리, 유전·육종, 생태 및 병·충해 순이었다. 연구의 목적, 내용, 결과 및 대상식물 등을 고려하여 보면, 1) 초본식물에 대한 보다 많은 연구, 2) 타산업 또는 학분 분야와의 공동연구, 3) 자원 보전적 연구 및 4) 연구주체자 간의 연구결과의 공유 등이 매우 요망된다. The articles, published in the Journal of Korean Forestry from Number 1(1962) to number 6, Volume 91(2002), were surveyed and investigated for the research trend analysis about resource-plants for special use or purpose, i.e edible plants, medicinal plants, feed resource, landscape plants, fiber plants, industrial usage, and bee plants. If the purpose or subject matter of the research was construction or furniture timber production, mushrooms and/or pulp and Paper, such research was not included in this study. These articles were classified again depending on the content of research into 14 categories : habitat environment, ecology, physiology, propagation, silviculture(tending and culture), genetics and breeding, identification, insect and disease control, animal-related research, cemponent analysis, vegetation survey, biotechnology, management, and review. Among the total 1,434 articles published, 396 ones (27,6%) were related with plants for special use or purpose. Vegetation survey was 60(15.2%) ; physiology 56(04.1%) ; genetics and breeding 56(14.1%) ; propagation 53(13.4%) ; and ecology 37(9.3%). Siviculture research field included 11 articles (2.8%), which indicates that the management of resource-plants is to far from economic income as seen in the low number of management research filed articles, i. e., only 6 reports(1.5%). Korean white Pine was most popular for research and included 42 articles ; Robinia pseudoacacia 23 Castanea crenata 14 : and ginkgo tree 14, Research related with these species had focused mainly or propagation, physiotogy, genetics and breeding, ecology and pest control. Based on this survey and analysis, the followings are suggested : 1. More research is required on forest herbaceous plants. 2. Cooperative research work with other industrial and/or scientific area is recommendable for commercialization including medicine, cosmetics, and food etc. 3. Research resource-plant conservation. which includes biology, social education and policy, should be supported for next generation. 4. Mutual correspondence and information exchange about the research results between researchers and institutes is more necessary than now.

Background : Bleeding after endoscopic procedure of the stomach carries an increased risk of morbidity and mortality. In case of oozing hemorrhage, not in active hemorrhage, powdered sodium alginate may play a role in control of bleeding with convenience. Therefore, we evaluated the clinical effect and efficacy of sodium alginate powder in upper G-Ⅰ bleeding. Methods : Forty-five patients who had upper G-Ⅰ bleeding after endoscopic procedure were enrolled in this study. Twenty-five patients of them were managed by the application of powder preparation of Sodium alginate(ALTO). The others were observed without treatment. The next day, we performed endoscopy in all patients to ascertain the hemostasis. Results : Of 25 patients managed with Sodium alginate, only two patients(8%) had bleeding (hemostatic rate : 92%), On the other hand, of 20 patients who did not receive any treatment, 3 patient(15%) had bleeding (hemostatic rate : 85%). There was no statistical difference between the two groups(p>0.05). Using other endoscopic procedure, We successfully treated the patient who continued to bleed. Conclusion : We evaluated the effect of the spary of sodium alginate on oozing hemorrhage. Although there was no statistical significance in our study, it seems that the spray of sodium alginate may be a useful method for the prevention of bleeding after endoscopic procedure.

28세 남자가 내시경적 점막절제술을 통해 저등급 위MALT 림프종으로 진단되었다. 병기설정을 위해 18F-FDG PET 검사를 시행하였고 우측 쇄골상부, 우측상/하부 기관주위, AP window 부위에 강한 섭취가 관찰되어 전이성 림프절로 판단하였다. 그러나, 우측 쇄골상부 림프절에서 시행한 절제생검에서 만성육아종성염증소견이 관찰되었고 조직의 결핵 중합효소연쇄반응에서도 양성 반응을 보였다. 2개월간 항결핵제의 사용 후 시행한 추적 컴퓨터단층촬영 검사에서 림프절 크기의 감소를 보여 최종적으로 위 MALT 림프종에서 광범위 림프절 전이로 오인된 동시성 림프절 결핵으로 진단되었다. A 28-year-old man was diagnosed as gastric MALT lymphoma in diagnostic EMR (endoscopic mucosal resection). He subsequently underwent an 18F-FDG PET. 18F-FDG PET showed intense multifocal uptake in right supraclavicular, right upper and lower paratracheal, and AP window areas that was considered radiologically to represent widespread metastatic lymphadenopathy. Excisional biopsy of a supraclavicular lymph node, however, revealed chronic granulomatous lymphadenitis with a positive reaction of Tb-nested PCR. After antituberculosis treatment for 2 months, a follow-up CT scan showed complete resolution of the lesions. Intense 18F-FDG uptake could be due to an infectious process such as synchronous tuberculous lymphadenitis. Therefore, this could mimic a malignant condition such as lymphoma with extensive lymph node metastasis due to a false-positive finding, which may lead to a misdiagnosis.

Although the treatment of gallbladder stones is mainly dependent on surgical intervention, recently medical treatment such as oral bill acid therapy, dissolution therapy with MTBE or extracorpareal shock wave lithotripy have been also performd. For the auccess, of these medical therapy. the composition of gallbaddser stones is a important factor. So, to predict the comical composition, we examined 100 cases of the surgically removed gallblraldder stoned by ultrasonaraphy. And we compared the ultrasonograplic findings of gallbladder stones with the chemical compotions and the features of cut surface. Alan we compared the presence of the calcification on the simple abdominal X-ray. The chemical components of gallbladder stones were analysed by ultrared spectrometer. Ultrasonographic findings were claesafied into five characeristic types; the shooting-star (SS) type, the crescent (C) type the half-moon (HM) kype, the full-moon (FM) type anal the star-dust (SD) type. The roved as fallows. In chemical compositions of gallstones, 67 cases (67%) were cholesterol stones with 26 eases (2^%) of pure cholesterol stones, and 30 cases (30%) of cholesterol-bilirubinate stones, bilruastnate stone were 25 cases (25%), calcium-carbanate stones were 7 cases (7%), and calcium pltcasphate stone was 1 case (1%). In ultrasonograhic fielding of gallstones, the SS types were 24 cases (24%), the C types 43 cases (43%), the FM types 16 uses (16%), the HM types 14 cases (14%) and the SD types were 3 cases (3%). In the relationship between tcltrasonographic findings and cheat composition, tine SS type itrcluded cholestro stones with 21 cases (88%). The C type included cholesterol stones with 30 cases (70%) and bilirubinate stones with 13 cases (13%). The HM types included chstrol stones with 9 cases (64%), bilruinate stones with 3 gases (24%) and calcium carbonate stones with 2 cases (14%). The FM types inch cholesterol stones with 5 cases (31%), bilirubinate stone with 6 cases (38%), calcium carbons a stones with 4 canes (25%), and calcium phosphate stone with 1 case (6%). The SD types incitude cholesterol stone with 2 cases (67%) and hilirubinatie stone with 1 case (33%). Cholesterol stone were found mainly in the C type (45%) and the SS type (31%). Bilirubinate stones were found mainly in the C type (52%) and the FM type (24%). In comparison between the presence of calcification on the simple abdominal X-ray and the chemical composition with ultrasonographic findings, 9 of 100 cases of gallbladder stones showed calcification on the simple abdominal X-ray with 2 choleBterol stonecs; 5 bilirulalnabe stone, 2 calciim carbonate stones. Non-cholesterol stones showed more frequent calcification finding than eholeacrol stones. In the features of the cut surfaces of the 100 gallbladder stones, the concenteric types were 64 cases (64%), the homogenous types were cases (26%), and to radiating types were 10 cases (10%). And there was no correlation between the features of the cutsurfaces of gallbladder stones and the ultrarsorographic findings. , In conclusion, the classification of ultrasonographic findings are useful to predict, the chemical compositions of gallblardder stones and to decide on the therapeutic method of gallbladder stones.
