Background : Electrolyzed acid water (EAW) is a new liquid chemical germicide containing a mixture of oxidizing species and prepared by mixing a small amount of salt with tap water in an electrolyzer. We attempted an in-use evaluation of the high-level disinfection capability of Cleantop WM-1□, a new endoscope reprocessing system using EAW. Methods : Forty-seven flexible endoscopes were randomly collected just after upper endoscopic examinations and were disinfected using Cleantop WM-1□. Parts of the endoscopes without contact to EAW were disinfected with 75% ethyl alcohol. Immediately after the disinfection procedure, samples were taken from the biopsy channel (S-1), tip of the insertion tube (S-2), the umbilical cord (S-3), and the angulation knob (S-4). Results : In EAW-disinfected parts of the endoscopes, the culture-positive rates were 4.3% (2/47) in S-1 samples and 12.8% (6/47) in S-2 samples. In ethyl alcohol-disinfected area, the culture-positive rates were 2.1% (1/47) in S-3 samples and 25.5% (12/47) in S-4 samples. The colony counts of culture-positive samples ranged from 1 to 144. Pseudomonas aerugi-nasa was recovered from the angulation knob of an endoscope, but other contaminating organisms were mostly : normal flora or opportunistic pathogens. Conclusion : Although part of the endoscopes disinfected with 75% ethyl alcohol were contaminated with more organisms than EAW-disinfected areas, Cleantop WM-1□ showed a relatively good disinfection efficacy in reprocessing patient-used endoscopes.

Strongyloidiasis is a parasitic disease caused by Strongyloides stercoralis which exists in two forms : the free living and parasitic forms. It exists in warm, moist climate in areas where there is frequent fecal contamination of the soil. After cutaneous invasion by the filariform larvae, petechial hemorrage, pruritus, papular rashes, edema, and urticaria occur. Infection commonly occurs in the proximal intestine of the gastrointestinal (G-I) tract but may extend from the stomach to the anus. Once the worm is established in the small intestine, the physical findings may include epigastric tenderness to palpation. The mucosal biopsy is an inefficient way of making the diagnosis because the worm is found in the biopsy specimen in only 2% of patients. Gastric strongyloidiasis is rare. We experienced a case of gastric strongyloidiasis diagnosed by the endoscopic biopsy and serologic test for parasite specific IgG antibody by micro-ELISA.

저자들은 비호지킨씨 림프종 환자에서 항암 치료 후 질환의 진행성 병변과 감별을 요했던 우폐 중엽의 단발성 종괴를 흉강경하 생검으로 폐 효모균증을 확진하고 amphotericin B와 fluconazole로 치료한 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Non-Hodgkin's lymphoma is monoclonal expansion of malignant B or T cells. The immunocompromised status in this disease is accompanied by many infections. The cryptococcosis, caused by Cryptococcus neoformans, frequently occurs in leukemia, Hodgkin's disease, sarcoidosis, diabetes mellitus, tuberculosis, and long-term steroid-using patients. Recent increasing incidence of fungal infection could be due to the spread of AIDS and transplantation. We experienced one patient with lung mass in Non-Hodgkin's lymphoma after three cycles of chemotherapy, which could not be discriminated from the newly developed lymphoma mass. Cryptococcus neoformans was isolated from the lung tissue obtained by thoracoscopic biopsy. Herein we report this case with brief review of pertinent literature.

사회복지 지방이양사업과 지방복지재정위기에 관한 연구

이재완(Lee, Jae-Wan) 한국지역사회복지학회 2010 한국지역사회복지학 Vol.0 No.35

본 연구는 사회복지지방이양사업 실시에 따른 지방복지재정의 위기를 규명하고자 하였다. 특히 현 정부의 감세정책으로 인해 지방재정의 재원감소가 초래되고 있다. 즉, 각종 세원(법인세, 소득세, 양도세, 종부세 등)의 세율인하로 국세가 줄어들어 자동적으로 지방 재정에 대한 이전재원이 줄어드는 결과를 초래하고 있다. 결국 사회복지분야 사업이 대폭지방으로 이양되어 있는 상황에서 지방재원의 감소는 지방정부의 복지관련 지출의 축소로 나타나고 있다. 따라서 본 연구에서는 지방정부의 사회복지불균형의 실태를 고찰하고, 이러한 상황을 해소하기 위해 중앙정부의 재정지원방식에 대해 검토하였다. 또한 사회복지 지방이양사업 선정의 비합리성과 이명박 정부의 감세정책으로 지방복지재정의 위기가 나타나고 있음을 규명하였다. 현재의 지방복지재정의 여건을 고려할 때 중앙정부와 지방정부의 역할분담의 재설정이 필요하다. 즉, 사회복지서비스의 재정책임은 중앙정부가 부담하고 서비스의 공급은 지방정부가 분담하는 방안이다. 이에 대한 구체적인 방안마련을 위한 학제적 연구의 필요성이 요청된다. This study is purposed to identify the financial crisis of local government according to the implementation of the act which is shifting responsibility for social welfare services from the central government to local government. The tax duction policy of the Lee"s administration causes financial deficit in local government because of the decrease in funding resources in local government. The financial difficulty in local government has negative effects on the social welfare expenditure. Under this consideration, this study is looking at the unbalance in social welfare expenditures in local government and examining the financial support system of the central government to solve the financial problem in local government. In addition, this study is examining the negative effects of tax deduction policy on the financial solvency in local government. Based on that, this study suggests role dividing between central and local government in providing social welfare services. The central government must have responsibilities in financial aspects. On the contrary, the local government must be more focused on providing social welfare services.

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.

이지은(Lee, Ji-Eun),이재완(Lee, Jae-Wan) 한국지방정부학회 2014 지방정부연구 Vol.18 No.1

이지은(Lee, Ji-Eun), 이재완(Lee, Jae-Wan) 본 연구의 목적은'삶의 질'에 대한 지역주민의 인식을 유형화하고 분석하는 데 있다. 지역주민의 삶의 질에 관한 주관적 인식을 분석하기 위해 Q방법론을 활용하였다. 지역주민을 대상으로 한 인터뷰 및 선행연구 검토를 통해 Q진술문을 작성하였고, P샘플은 서울시에 거주하고 있는 지역주민 40명을 대상으로 하였다. 분석 결과, 삶의 질에 대한 주민인식은 ① 기본적 요건 지향, ② 물질적 요건 지향, ③ 비물질적 요건 지향으로 유형화되는 것으로 나타났다. 본 연구는 삶의 질에 관한 인식이 지역주민마다 다를 수 있으므로, 지방자치 수준에서 숙의민주주의를 실현할 수 있는 공론의 장을 마련할 필요가 있다는 점을 시사한다. 지방정부가 지역주민들의 삶의 질을 향상시키는 정책을 수립할 때 다양한 주민들의 인식과 의견이 반영될 수 있도록 하여야 할 것이다. The objective of this study is to classify and analyze citizens' perceptions on 'quality of life'. In order to examine quality of life as perceived by citizens, Q-methodology was used. A set of Q-statements was constructed with reference to field interviews of citizens and literature review of the precedent study, and it was rated by 40 citizens residing in Seoul. The results of this study revealed that citizens' perceptions of quality of life could be classified in terms of three perspectives: 1. Basic conditions orientation, 2. Material conditions orientation, and 3. Non-material conditions orientation. Based on the analysis results, this study suggests that as citizens' perceptions of quality of life can be diverse, there is a need to develop a public sphere where deliberative democracy would be realized and advanced at local government level. By creating and developing public spheres, local governments would be able to take citizens' perceptions and opinions into account better when establishing policies for improving citizens' quality of life.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

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.
