가성 장폐색은 기계적인 폐색부위가 없이 복부팽만과 구토 등 장폐색의 증상과 징후가 나타나는 질환을 말하며, 선행원인을 찾을 수 없는 원발성 가성 장폐색과 다른 질환에 이차적으로 발생하는 속발성 가성 장폐색으로 나눌 수 있다. 당뇨병은 잘 알려진 속발성 가성 장폐색의 원인이지만 실제로 당뇨병에 의한 가상 장폐색의 발생 빈도는 매우 드문 것으로 보이며, 가성 장폐색의 적절한 치료에 대해서는 아직 논란이 있다. 저자들은 2형 당뇨병 환자에게 대장에 국한된 급성 가성 장폐색을 진단하고 보존적 치료를 시행하여 호전된 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Colonic pseudo-obstruction is a disorder characterized by gross dilatation of the colon in the absence of any anatomic lesions, which obstructs the flow of the intestinal contents. Diabetes is a well known cause of secondary pseudo-obstruction but its prevalence in rare and not well understood. A 59-year-old woman patient was admitted due to abdominal distension and nausea of a day's duration. She was diagnosed with diabetes 15 years ago, but the condition had been poorly controoled. On the abdominal radiographs, there were marked small and large bowel dilatation with the, exception of the descending colon. Our initial diagnosis was mechanical obstruction, but the possible causes were not found. Also, we could not find another cause of the secondary pseudo-obstruction, with the exception of diabetes mellitus. Thus, she was diagnosed with a diabetes induced intestinal pseudo-obstruction. The colonic dilatation was resolved by conservative management and she became comfortable in 10 hospital days, and was subsequently discharged.

This study was conducted to suggest appropriate methods for management of urban forest after investigating the present condition and problems of urban forests by analyzing vegetation and soil properties in urban forests in the Daejeon. On the basis of our research, Pinus rigida dominate Gyejoksan and Bomunsan. Pinus densiflora dominate Wolpyeong park and Quercus acutissima dominate Namsun park. On the basis of our result of analysis of soil chemical properties, all investigated areas have low pHs, available phosphates and exchangeable cations. They indicate that the soil of those areas have been acidifying progressively. Soil hardness measurements were conducted to know the conditions of trampled soils and the results of them show that soil hardness in Namsun park was higher than the others. This indicates that human interference affect the health of the urban forest.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Surface migration of Poly(perfluoroalkylethyl acrylate)(PFA)/silica nanocomposites added in poly(methylmethacrylate()(PMMA) was investigated by comparing before and after annealing. In this study, surface migration characterizations of PFA/silica composites were measured by SEM(Scanning Electron Microscopy) and contact angle measurement. Their surface free energies were calculated with contact angle data by geometric mean approximation. The contact angles were increased and the surface free energies were decreased, according to increasing the graft density of nanocomposites and decreasing the concentration of PMMA, respectively. It was confirmed that PFA/silica nanocomposites were successfully migrated toward the surface of the PMMA film.

‘제3세대’이후 국내 러시아 연구의 현황과 과제 : 사회과학을 중심으로

박수헌,신범식 서울대학교 러시아연구소 2006 러시아연구 Vol.16 No.2

Since the mid-1990s, Russian Studies in Korea have been in the stage of "relative stabilization" after undergoing the ups and downs in the previous years. The rise of the "third generation" scholars, many of which returned to Korea after earning their doctoral degrees in Russia, has contributed to this trend. The current research, based on a comprehensive review of social science works on Russia, published as M. A. and Ph.D theses, in book forms and monographs, and as articles in 12 academic journals during the past decade in Korea, shows the following developmental tendencies in the Russian Studies in Korea since the mid-1990s. First, the number of Korean specialists on Russia has consistently increased. Second, the scope of research has been extended in spatial dimension as well as in research topics. In the former, while CIS countries other than Russia have increasingly became the subject of research, the investigation of local politics and economy in Russia has also grown. In the latter, topics have been more diversified beyond the traditional fields of politics, economy, society, and history into education, law, media, anthropology, and political geography. Third, the cases of field researches and surveys have continued to increase, which can contribute to a qualitative progress in the Russian Studies in Korea. Fourth, more research efforts have been devoted to the analysis of various aspects of Russia from a comparative theoretical perspective. Fifth, new attention has been called to the methodological issues in understanding the Russian experiences. Despite these new developments and achievements, however, Russian Studies in Korea still offer the room for continuing improvement. First, compared with those countries with more advanced Russian Studies, the Russian Studies community in Korea is still much small, and there are very few specialists on other CIS countries than Russia. Second, Russian politics and economy still command a disproportionally high position in terms of research topic. Third, researches are lopsidedly tilting toward policy-oriented studies rather than contributing to strengthening the foundation of Russian Studies. Fourth, the previous tendency to approach the Russian experiences from the viewpoint of break with the past has not been fully overcome. Fifth, although efforts have been made for establishing a "Korean style of studying Russia", the Western approaches to the Russian realities still enjoy a disproportionately high popularity. Sixth, strenuous endeavor among the Russian Studies community is required for implementing interdisciplinary researches of Russia as subject of area studies.

This study investigates the preparation of poly(perfluoroalkyl acrylate)[PTA]/silica composite particles by surface polymerization and their characteristics according to surface polymerization time. The particles were prepared by "grafting-from" technique by immobilizing self-assembled initiator and surface radical polymerization from silica particle surface. Characterization was done by contact angle and sliding angle measurements, surface roughness measurement and surface free energy estimation Contact angle were inversely proportion to sliding angle. Graft density(GD) and contact angle of composites increased according to polymerization time. On the other hand, surface free energy and sliding angle were decreased according to increment of polymerization time.
