민선향 연세대학교 교육연구소 2004 연세 교육연구 Vol.17 No.1
최근 전문대학들이 직면하고 있는 내부적·외부적 환경요인들은 단기직업교육기관으로서의 전문대학 정체성을 위협하고 있다. 이 중 학령인구 감소에 따른 전문대학의 다양한 입학정책으로 야기되는 학생들의 기초능력 저하 문제는 가장 큰 문제로 인식되고 있다. 빠른 직업세계의 변화에 보다 유연하고 능동적인 대처를 하기 위해서는 그 어느 때보다도 기초직업능력이 절실히 요구된다. 전문대학생의 기초직업능력의 결손은 결국 평생직업능력으로 이어지지 못하며 이는 전문대학 교육의 실패를 의미한다. 그러므로 기초직업능력 강화는 전문대학의 질 관리 측면에서 반드시 고민해야하는 과제다. 이러한 문제의식을 갖고 본 연구는 전문대학생의 기초직업능력 강화를 위한 총체적인 틀을 제공하고자 하였다. 이를 위해 기초직업능력, 기초학습능력의 개념, 그리고 기초능력과 직무와의 관련 등 문헌연구를 통해 기본적 개념과 관련 논의들을 살펴보았고 이를 토대로 전문대학생을 위한 기초직업능력 강화 방안 모색 직업교육의 총체적 학습 시스템 안에서 탐색해 보았다. 앞으로 우리나라 전문대학과 전문대학생의 현실을 반영한 기초직업능력 강화 관련 실증 연구 및 프로그램 개발 등 실제 사례들을 통해서 그 효과성을 입증하는 다양한 연구들이 향후 과제가 될 것이다. Recently, junior colleges have faced many difficulties in the internal and external environments. Especially, low academic level of students is one of the big problems. For the competition of junior college, the importance of basic workplace literacy should be emphasized. The purpose of the study was to provide framework for the development of basic workplace literacy of the junior college students. In this study, prior studies and reports were reviewed to establish the conceptual and theoretical foundations of basic workplace literacy. Then the following contents were examined: the need of workplace literacy for the junior college, conceptualization of workplace literacy and related perspectives, the direction of vocational education for the development of basic skills, and the effective program frame for the development of workplace literacy. This framework derived from interpretative perspective. A number of strategies are suggested. The direction of vocational education is the integration of vocational and academic education, work-based learning, school-based learning, and connecting activities. The program frame was fccused on integrations of academic and vocational area; contextual 1- which enhances student learning and engagement; teachers who provide high expectations and positive feedback. For further research and development, an empirical study related in basic workplace literacy will be needed.

Perilla is a Korean traditioanal crop and perilla seeds are frequently consumed in many food products as seasonings and seed oil in this country. To our knowledge, this is the first report on perilla seeds-induced anaphylaxis and specific IgE determination to perilla seeds. We experienced a 20-year old man who had developed whole body urticaria, facial swelling, and shortness of breath 2 hours after eating two dumplings seasoned with perilla seeds. He had developed two more episodes of allergic reactions after eating some food seasoned with perilla seeds before. The skin prick test with perilla seed extracts showed strong positive reactions, and serum specific IgE antibodies to perilla seeds were highly detected by ELISA. Oral provocation test showed rhinitis, conjunctivitis, urticaria, and severe asthmatic reaction. (Korean J Asthma Allergy Clin Immunol 2006; 26:94-97)

Purpose: Cancer stem cells have the characteristics similar to the normal stem cell but are cancer cells. Sphere forming culture has been adapted as a culture method for cancer stem cells. In this study, we validated to optimal culture condition for sphere formation of hepatocellular carcinoma cell line using three different types of culture media. Methods: Huh7 cells were plated in different culture media allowed for sphere formation. M1, Dulbecco’s Modified Eagle’s medium (DMEM)-high glucose with fetal bovine serum (FBS); M2, DMEM-high glucose without FBS; and M3, DMEM-F12 (Gibco, Grand Island, NY, USA) with B27, epidermal growth factor, basic fibroblast growth factor (bFGF, Invitrogen, Seoul, Korea). Sphere formation was observed by light microscope. Proliferation of the sphere-forming cells was evaluated by Cell counting kit-8 (CCK-8) analysis. Results: Cells in M1 and M3 media were formed sphere. Sphere-forming cells in M1 and M3 were bigger than M2 cells and had similar morphology. Sphere-forming cells in M3 media showed higher level of cell proliferation than M1 and M2 cells on 15 days, while sphere-forming cell in M1 media were exhibited higher level than others on post 20 days. Proliferation of M2 cells did not improve. Conclusion: Results showed that sphere-forming cells in M1 and M3 media had similar character. So, it is assumed that a growth factor- free medium is adaptable or efficient tool for in vitro cultivation of cancer stem cells, because the tool shall be reduced expense for experiments without the adding of growth factors.

MLA system is used to reduce cost and friction. But MLA system doesn't have the ability of controlling the clearance between cams and valves. MLA glade is selected by measuring the distance between valves and cams to minimize the clearance of valves considering thermal expansion of valves. So, after fully warming-up periods the valve clearance is nearly zero, but before warming-up, there is a valve clearance. Especially at cold condition, the clearance is relatively large and can cause some problems. In this study, valve motion like velocity, life and rotation was studied at various valve clearance conditions by changing MLA grades.

Spanish 'que' shows various syntactic functions, particularly as a conjunction and as a relative pronoun. Moreover it has another syntactic function called 'otro que' or 'the third que', which is a theme of this paper. We have searched many commutative sentences along with 'tener+que+inf.' and 'tener+indefinite pronoun+que+inf.', so that we have to conclude that it is very probable to define it as 'otro que' or 'the third que' in the structure of 'tener+que+inf.' and ‘tener+indefinite pronoun+que+inf.'.

목적 :갑상선에서 직경 10 mm 미만의 소결절의 초음파 소견을 분석하여 양성과 악성결절의 감대 상 및 방 법 : 58명의 환자에서 수술 및 세침흡인검사에 의해 병리조직학적으로 확진된 최대직경 10 mm 미만의 갑상선 소결절 72예(양성 44예, 악성 28예)의 초음파 소견을 후향적으로 분석하였다. 양성과 악성결절에서 병변의 경계, 내부에코의 양상 및 미세석회화, 결절내부 낭성변화, 결절주위 저에코의 테두리 존재여부를 비교하였다. 결과 : 초음파소견에서 악성결절은 불분명한 경계면을 보이는 경우가 많았다(61% vs 11%, p < 0.05). 내부에코 양상에서는 양성결절은 등에코나 고에코를 보이는 경우가 많았으며(45% vs 18%, p < 0.05) 악성결절은 현저한 저에코를 보이는 경우가 많았다(39% vs 18%, p < 0.05). 미세석회화는 악성결절에서 더 많이 관찰되었고(36% vs 9%, p < 0.05) 결절내 부의 낭성변화(39% vs 7%, p < 0.05) 및 결절주위 저에코의 테두리(41% vs 18%, p < 0.05)는 양성결절에서 더 많이 관찰되었다. 결론 : 초음파는 갑상선 소결절에서 양성과 악성결절의 감별에 도움이 될 것으로 사료된다. PURPOSE : To evaluate the usefulness of ultrasonography in the differentiation between benignity and malignancy in the evaluation of small thyroid nodules (the longest diameter < 10 mm). MATERIALS and METHODS : Fine needle aspiration or surgery was performed for the evaluation of seventy two (44 benign and 28 malignant) small thyroid nodules from fifty eight patients. Ultrasonographic findings were retrospectively reviewed for the margin, echogenecity, presence of microcalcification, intranodular cystic change and peripheral hypoechoic halo. RESULTS : Ill-defined margin was more common in malignant nodules (61% vs 11%, p<0.05). In internal echogenecity, either iso- or hyperechogenicity was more coomon in benign nodules (45% vs 18%, p<0.05) while malignant nodules were often markedly hypoechoic (39% vs 18%, p<0.05). Malignant nodules contained more microcalcifications (36% vs 9%, p<0.05) whereas benign nodules often showed intranodular cystic change(39% vs 7%, p<0.05) and hypoechoic halo (41% vs 18%, p<0.05). CONCLUSION : Ultrasonography can be useful in the differentiation between benign and malignant small thyroid nodules.
