      • A Study on Small Business Development and Support Policies

        Yun,Jeong-keun,Jeong,Eun-hye 한국유통과학회 2011 한국유통과학회 학술대회 논문집 Vol.2011 No.-

        The number of small businesses being founded in the nation is constantly increasing and various kinds of aggressive efforts are being made to have competitiveness. As such, political support by the government with regards to small businesses that has productivity and competitiveness needs to increase. Foundation of small businesses is being promoted by the Government to boost the economy, and interest in foundation of the business is high amongst not only college students but even general workers. Thus, the purpose of this study is to examine problems regarding foundation of small businesses and to give new businesses competitive edge by presenting political answers to these problems. After analysing status and current issues of foundation of small business, the paper suggested positive policy alternatives. Existing studies on small businesses were focused on promotion of small and medium distributors, and studies on policy alternatives aimed directly at promoting the businesses are insufficient. Further studies are needed to examine political alternatives from point of view of roles and support of non-profit organizations that the Government is responsible for support of small business.

      • 創作 시나리오를 이용한 討議式 學習活動이 中學生의 힘과 運動의 槪念 變化에 미치는 影響

        윤은정,육근철,이춘우 공주대학교 사범대학 과학교육연구소 1996 과학교육연구 Vol.27 No.1

        많은 중학생들은 기본적인 물리 개념에 대해서 오개념을 가지고 있으며 물리 교과를 매우 어렵게 생각하고 있기 때문에 물리교과에 대해서 흥미를 잃고있다. 그래서 본 연구에서는 힘과 운동에 대해 학생들이 가지고 있는 사전 개념을 조사한 후 전통적인 방법으로 수업을 받은 통제반과 교사의 역할이 없이 창작 시나리오를 가지고 토의활동을 한 실험Ⅰ반과 교사가 적절히 역할을 하면서 창작 시나리오를 가지고 토의활동을 한 실험Ⅱ반의 힘과 운동에 대한 개념변화를 조사·비교하여 토의학습의 가능성을 제안하였다. Many middle school students usually have some misconcepts and prejudices against the basic physical concepts. They have much trouble in understanding the several physical concepts in their class, especially on force and motion. Accordingly, Many students are losing interest in their physics class. Therefore, We studied on the change of the concepts about the force and motion through the learning discussion by comparision to the traditional method in this study. This study also intended to find out the effectivness of discussion method(Group Ⅰ: students-students, Group Ⅱ : students-teacher-students) after presentation of the creative scenario

      • 한국어 불규칙 용언처리를 위한 연구

        윤근수,이교운,박용욱 울산과학대학 1999 연구논문집 Vol.26 No.1

        한국어 정보처리를 하기 위해서는 가장 기초기술인 형태소 분석이 이루어져야 한다. 한국어의 용언은 어미의 활용으로 인하여 형태소분석을 상당히 까다롭게 하는 특성을 가지고 있으며, 대부분의 어절을 대상으로 용언의 불규칙 현상이 있는 지를 조사해야 하므로 시스템의 속도를 떨어뜨리게 된다. 따라서 이 논문에서는 용언 불규칙현상을 분류하고 알기 쉽도록 도식화하면, 전체 시스템의 속도를 높이기 위한 새로운 자료구조 도입과 알고리즘을 소개한다. Korean Morphological analysis is basic technic of Korean Information processing. Korean morphological analyzer is complicated because of irregular verbs. In this paper, we suggest analysis, diagram, and algorithm of korean irregular verbs processing. The system becomes very efficient because the number of dictionary accesses is minimized. The system makes easy to analyze unknown words like compound nouns without adding them to the dictionary.

        Emissions of air pollutants (TSP, SO2, NO2, CO, and HC) was estimated in Changwon city that has the industrial complex and basin terrain. We found that the emissions of TSP, SO2, NO2, CO, and HC were 897 tons, 3,287 tons, 5,706 tons, 10,057 tons, and 1,470 tons for a year, respectively and the main source of air pollutants were vehicle. The ratios of vehicle emissions to total emissions ware TSP 63.8%, SO2 26.1%, NO2 65.5%, CO 91.0%, HC 94.4%. The ratios of industry emissions to total emissions were TSP 30.8%, SO2 60.2%, NO2 25.2%, CO 6.4%, HC 3.7%. The ratio of life emissions to total emissions are TSP 5.4%, SO2 13.7%, NO2 9.3%, CO 2.6%, HC 1.9%. The concentration distributions of air pollutants simulated by ISCST3 model were similar to its emission distributions, and relatively high concentrations of air pollutants occurred in the Palyong-dong (industrial area) and Banlim and Chungang (residual area).

        In order to show the effect of a vast point pollutant source on air quality of Pusan Thermoeletric Power Plant and its surrounding area, air quality around Pusan Thermoeletric Power Plant was simulated by ISCLT-2 which was supplied by EPA. For this purpose the emission amount of SO_2, NO_2 and TSP was calculated and atmospheric stability was classified for a recent decade(1985~1994) in Pusan. A result of the emission amount showed that much amount of NO_2, NO_2 and TSP are emitted from industrial area. It was clear that NO_2 is much emitted from line source and industrial area. And as a result of classification of atmospheric stability, neutral, stable and unstable state were 58%, 24.1% and 17.9%, respectivly. The result of ai quality simulation by ISCLT-2 showed that Pusan Thermoeletric Power Plant is affecting on the increse of 2.0ppb, 3.0ppb and 5.0㎍/㎥, SO_2, NO_2, and TSP respectively at its surrounding area, site A-3 which was located westward 2.2㎞ distance from Plant

      • 결핵성 육아종에서 Thioredoxin peroxidase-2 의 발현

        박근호,유형륜,정영진,윤기중,한원철,유대열,문형배 圓光大學校 醫科學硏究所 1999 圓光醫科學 Vol.15 No.2

        Background: Thioredoxin peroxidase(TPX) is a kind of recently discovered antioxidant enzyme which react as rapid hydrogen ion donor for the removal of hydroperoxide. The action and distribution of the TPX was poorly understood in the human diseases. This experiments were designed for the study about the distribution of the TPX in the chronic granulomatous inflammation and about the correlation between the expression of TPX and the site of inflammation, histological activities of tuberculous inflammation or existence of mycobacterium in the inflammatory foci. Methods: The immunohistochemical stains were performed for the localization of the TPX-2 in the epithelioid cells, giant cells and lymphocytes in the chronic granulomatous inflammation. The tissue sections were obtained from the paraffin blocks of the 54 cases of tuberculosis (lung 21 cases, lymph node 12 cases, bone and soft tissue 12 cases, kidney 9 cases; active 33 cases, inactive 21 cases by the histologic classification; presence of mycobacterium 15 cases, no mycobacterium 39 cases by PCR reaction). Results: The expression of TPX-2 was 16.7% in the giant cells, 27.8% in the epithelioid cells and 100% in the lymphocytes of tuberculous inflammations. The expression of TPX-2 in the giant cells and epithelioid cells of the tuberculosis were 28.6% and 57.1% of the pulmonary tuberculosis; 33.3% in each cells of the renal tuberculosis; 0% in each cells of the lymph node or bone and soft tissue tuberculosis. The expression of TPX-2 in the giant cells and epithelioid cells were 9.1% in each cells of the active tuberculosis and were 28.6% and 57.1% in each cells of the inactive tuberculosis by histologic classification. The expression of TPX-2 in the giant cells and epithelioid cells was 40% in each cells of tuberculosis which mycobacteria were detected and the expression of TPX-2 was 7.7% and 23.1% in each cells which mycobacteria were not detected by PCR reaction in the paraffin embedded tissue. Conclusions: The above results were summarized that the TPX-2 in the giant cells and epithelioid cells were more frequently expressed in the inactive tuberculosis than in the active tuberculosis. These results suggest that the TPX-2 is a kind of regulating or suppressing factors in the activity of the tuberculosis.

      • HBeAg 양성인 만성 간염에서 라미부딘 치료전 HBV Core Promoter 서열이 약제내성 발생에 미치는 영향

        윤영근,김연수 순천향의학연구소 2004 Journal of Soonchunhyang Medical Science Vol.10 No.1

        <Background> Lamivudine is a potent inhibitor of RNA-dependent DNA polymerase of HBV. However its efficacy is limited by emergence of drug-resistant mutant. Mutation of HBV core promoter (CP, T1762 and A1764) is known to be associated with the reduction of transcription of precore mRNA and development of HBeAg-negative phenotype. Therefore, it could be assumed that the CP sequence might influence the responsiveness to antiviral therapy such as lamivudine in HBeAg-positive chronic hepatitis B. This study was carried out to find out if pretreatment CP sequences are associated with the development of lamivudine resistance in HBeAg-positive chronic hepatitis B. <Method> HBV CP sequences were analysed directly from the pretreatment sera of eight patients in whom high level of HBV DNA breakthrough occurred during the treatment, which were compared to those from eight patients who cleared HBeAg without the breakthrough. HBV polymerase sequences were also analysed in the patients with the breakthrough. <Results> Serum HBV DNA level who had the breakthrough was 2653±1459 pg/mL and 1405 ± 403 pg/mL in the patients who cleared HBeAg. All the patients with DNA breakthrough showed YMDD mutation (4 with Met552Val and Leu528Met and 4 with Met550Ile). Among the patients with the breakthrough, baseline CP sequence was wild type (A1762, G1764) in three, A1762 and A1764 in three, and T1762 and A1764 in two patient. On the other hand, among the patients who cleared HBeAg, seven patients(88%) haboured T1762 and A1764 mutation(p=0.018) at pretreatment period. Remaining one patient had wild type CP (A1762, G1764), however precore mutation(A1896) was found in this patient. <Conclusion> It is likely that emergence of lamivudine-resistant mutant or HBeAg seroconversion is influenced by the baseline HBV CP sequence in HBeAg-positive chronic hepatitis B.
