홍원표,양현수,장자순,김철규 忠南大學校 産業技術硏究所 1988 산업기술연구논문집 Vol.3 No.2

Terminally functionalized molecules are essential building block for the formation of polymers by polycondensation reactions. It is the major goal of this research to establish new routes for the preparation of such molecules by selective oxidation reaction of cyclohexene, using ozone as an oxydizing agent. To this purpose, it has been explored, whether the usual course of the ozonolysis of olefins can be modified with the help of specific catalyst in order to introduce the desired functional groups. In particular, the ozonolysis of cyclohexene in hydrocarbon solvents and in the presence of pyridine has been tested with the goal of preparing molecules containing one aldehyde and one carboxylic acid group. Ozonolysis of cyclohexene in hydrocarbon solvents such as methylene chloride and pentane can be guided by catalysis with pyridine, such that the reactions afford desired molecules. In this manner, pyridine catalized ozone oxidation converted cyclohexene into the corresponding 6-oxohexanoic acid(45.87%), adipaldehyde(14.68%), and polymeric ozonide(39.45%), via the ω-formyl carbonyl oxides in CH₂Cl₂at 0℃.

이규원,옥철호,장태원,정만홍 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.4

Background: To investigate the association between bronchial anthracofibrosis(AF) and tuberculosis(TB). and the clinical utility of high sensitivity C-reactive protein(hsCRP) for diagnosis of active pulmonary TB in patients with bronchial AF. Method: Eighty three patients(62 women and 21 men ranging in age from 55 to 87), who were diagnosed with bronchial AF by a bronchoscopy, were enrolled in this study. The hsCRP was measured in patient's blood. The hsCRP results were compared with the bacteriological, and clinical finding. Results: The common respiratory symptoms were cough(70%), sputum(35%), dyspnea(20%), and hemoptysis(10%). The sputum AFB smear, culture were positive in 20(22.8%) and 37(44.5%) patients, respectively. The level of hsCRP in patients with postive culture was significantly higher than that of patients with negative culture.(4.67±7.5, 0.90±1.59, p=0.005). Of 63 patients with negative smear, the level of hsCRP in patients(n=18) with positive culture was higher than that of patients(n=45) with negative culture.(3.39±5.78, 0.92±1.50, p=0.013). Of 20 patients with negative smear and positive culture who were empirically treated with anti-TB medication, 11 patients showed radiologic response. and their level of hsCRP was higher than that of 9 patients who showed no radiologic response.(1.56±1.89, 0.81±0.10,p=0.03) Conclusion: hsCRP appears to be useful diagnostic tool for predicting active pulmonary tuberculosis. in patients with bronchial AF.

This study aims to present the basic data for the establishment of indoor optimal thermal environment in housing for the aged by through field and subject response survey and experiment in model living room. As the first pace of study, the thermal-environment factors were defined by the measurement of physical thermal environment element (dry bulb temperature, radiative temperature, relative humidity, and air velocity) and the environmental needs of the residents was investigated through the questionary survey of the response to thermal environment in welfare facility with radiation heating for the aged in Teagu during winter in 2001. As a result of it, a model living room was designed and structured as a actual domestic room. Physical thermal-environment factors and environmental needs of the occupants in radiative heating space were examined thoroughly by measuring physical thermal environment element and investigating subjective response according to varied condition. The result of study can be summarized as follows; The value of the floor temperature in model living room was 30~34℃ according to temperature control of a constant temperature water tank. In particular, the value of the floor temperature was 33~34℃ and air temperature was 27~28℃ when the constant temperature water tank was 70~80℃. At this point, the value(38~42%) of indoor relative humidity was in the standard(37~48%) of relative humidity comfort. And also, occupants felt somewhat warm at the body on the whole as well as at the lower part of the body. However, the response of occupants was uncomfortable comparatively at the upper part of the body. The reason of that was seemed to be lack of ventilation and stifling atmosphere of the spot.

In this paper, an integrated developing environment(IDE) for a biped robot is presented, through which a new path planning algorithm is designed. The IDE is composed of four modules, each of which is designed by using the object-oriented programming techniques. Four modules have the capability of gait control, path planning, mission-level language interpretation, and monitoring respectively. Also, each module exchanges its information each other through database. The new path planting a1gorithm is composed of an environment analysis algorithm and a path search algorithm, and is used in the IDE. In this paper, an extended visibility graph algorithm is proposed as the environment analysis algorithm and the A algorithm is used as the path search algorithm for the path planning of biped robots. Since the path planning a1gorithm is designed by using the object-oriented techniques and is also implemented within the IDE, it has a good adaptability to the changes of algorithm and construction, and also has a high reusability of the designed capabilities.

김영규,민경수,이무섭,김동호,복원길,홍석기,김호재 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.2

연구목적: 만성 경막하혈종은 두개골 천두술및 혈종배액으로 쉽게 치료될 수 있는 예후가 양호한 질환으로 알려져 있으나, 혈종의 재발 및 합병증이 드물지 않게 발생하기도 한다. 본 연구는 두개골 천두술 및 혈종배액으로 치료받은 102예의 만성 경막하혈종 환자들을 분석하여 혈종의 재발 및 수술후 합병증과 관련된 요인들을 분석하고자 하였다. 대상 및 방법: 만성 경막하혈종으로 진단되어 두개골 천두술 및 혈종배액술법으로 본원 신경외과에서 수술치료받은 102명의 환자를 대상으로 하였고, 입원진료기록 및 방사선소견을 후향적으로 분석하였다. 재발 및 합병증의 발생과 관련된 요인으로는 수술전 환자의 나이, 의식상태, 양측성여부, 뇌실질의 위축정도, 수술후 기뇌의 양, 전신질환여부에 대하여 분석하였다. 결과: 재발의 빈도는 9.8% 였으며 재발과 관련된 요인으로는 양측성, 고령, 수술후 뇌실질재팽창정도(뇌 실질위축, 잔여수액, 기뇌)가 관계가 있었으나 환자의 예후에는 영향이 없었다. 합병증의 종류에는 수술후 급성출혈 5예 및 경막하 농양 1예가 있었으나 이는 모두 출혈성전신질환 또는 면역결핍증이 동반된 환자에서 발생하였고 예후가 불량하였으며, 긴장성 기뇌가 1예발생 하였다. 결론: 전신질환의 동반여부가 합병증의 발생 및 환자의 예후에 가장 중요한 영향을 미쳤으며, 비록 예후에는 영향이 적으나 혈종의 재발의 빈도가 드물지 않으며 기뇌의 방지 및 배액방법의 개선으로 재발의 빈도를 줄일 수 있을 것으로 생각된다. Purpose : Most of chronic subdural hematomas(SOH) are amenable disease with simple cranoistomy drainage, but the recurrence of SDH or development of complications after surgery is not uncommon. To see the prognostic factors related to outcome the recurrence of chronic subdural hematoma and development of complication were analysed in 102 cases of chronic SDH after craniostomy drainage. Materials and Methods: We studied 102 chronic SDH patients treated with craniostomy drainage. Clinical and radiological records were reviewed retrospectively. We analysed the recurrence and complication rate, factors related to the development of recurrence and complications. Results: The rate of recurrence of chronic SDH was 9.8% and factors related to recurrence were bilaterality, old age, and postoperative intracranial environments for brain reexpansion(degree of brain atrophy, amount of residual fluid, amount of intracranial air). Intracranial complications after surgery were developed in 7 cases(6.9%), 5 postoperative bleedings, 1 tension pneumocephalus, 1 subdural empyema. Conclusion : Preoperative clinical condition and association of serious sytemic disease were of major importance in prognosis. The recurrence of chronc SDH was not uncommon, Even though the recurrence was not related to the outcome, great care should be paid on the patients with high risk group.

대학 시간강사의 사회의식

김규원 慶北大學校 社會科學大學 1999 社會科學 Vol.11 No.-

한국은 세계적으로 드물게 급속한 고등교육의 팽창을 경험하였는데, 최근 들어 대학원 이상의 고학력자들 사이에서 고용 문제가 대두하고 있다. 특히 대학 시간강사의 고용 상태의 심각성은 지식기반경제에서 주요한 사회문제이다. 이러한 문제의식 아래, 본 연구는 대학 시간강사의 사회의식을 분석 · 진단하고, 부정적인 사회의식을 강제하는 시간강사의 준실업문제의 해결방안을 모색한 것이다. 대학 시간강사 문제를 해결하는 최선의 길은 고등교육개혁과 대학발전방안과 연계해서 검토하는 것임을 주장하고 있다. 구체적으로, 대학 시간강사는 소외의식이 강한 것이 특징인데, 이는 그 사회적 지위와 관련한 위신과 존경이 아주 낮은 데 기인한다. 그런 만큼, 문제의 해결책은 시간강사의 위상을 대학조직체와 연관하여 제고하는 것이 관건이다. 대학 생존전략의 일환으로써 해당 지역사회의 각종 조직체와의 밀착관계를 형성하는 연결고리로서의 시간강사 집단의 역할이 기대되는 것이다. 향후 고등교육의 개혁은 시간강사 집단의 대사회적 기능을 강화하는 방향으로 추진할 것이 요청된다. South Korea has experienced the fastest growth of higher education in the world. As a result, there is an increasing problem of underemployment among the recent Ph.D.'s, whose temporal occupations are called as part-time lecturers. Judging from the importance of a knowledge-based economy, the nowadays hardships of part-time lecturers should be a social issue, with which the Koreans have to deal sincerely. This paper intends to identify the characteristics of social consciousness of Korean part-time lecturers at the university level, and then to find out a plausible solution for the problem in concern, centering upon the educational reform of higher education system. To be specific, Korean part-time lecturers are suffering from a very high level of alienation, for their social status is lacking for the prestige as well as the esteem that a professional work deserves. This study suggests that a desirable solution should be related with the empowerment of part-time lecturers such as enhancing their organizational roles in the processes of linking the university system to the civil organizations of the community. Finally, it argues that Korean educational reform in the near future should strengthen social functions of part-time lecturers, who are least utilized but most prepared in knowledge and skill for the national development.
