        중재 시술용 기능성 기관-기관지 팬텀을 제작하고, 스텐트 삽입술을 시행하여 그 유용성을 평가하고자 한다. 중재 시술용 기능성 기관-기관지 팬텀은 실리콘으로 제작하였으며, 기관을 통하여 스텐트 삽입술이 가능하도록 삽입구를 제작하였다. 팬텀은 지점토를 이용하여 인체와 동일한 형태로 기관, 기관지 분지부와 양쪽 상부 기관지를 재현하였고, 사각형의 틀에 지점토를 고정시킨 후 액상의 실리콘을 채워 건조시킨 후 지점토를 제거하여 제작하였다. 인체, 동물, 팬텀에서 기관지스텐트 삽입 후 흉부 촬영 필름의 농도와 기관지 분지부의 각도를 측정하여 비교하였다. 기관지스텐트는 세선의 교차가 다른 2가지(X-type, Y-type) 형태를 삽입하였으며, 스텐트 삽입술 후 기관 상부, 기관 분지부, 좌기관지, 우기관지, 스텐트 삽입부의 필름농도를 측정하였다. 필름농도는 기관 상부의 경우, 인체 0.76(±0.011), 동물 0.97(±0.015), 팬텀 0.45(±0.016)이었고, 기관 분지부의 경우는 인체 0.51(±0.006), 동물 0.65(±0.005), 팬텀 0.65(±0.OO8)이었고, 우기관지의 경우는 인체 0.14(±0.OO8), 동물 0.59(±0.014), 팬텀 0.04(±0.007)이었고, 좌기관지의 경우는 인체 0.54(±0.004), 동물 0.54(±O.008)로 팬텀 0.08(±0.OO8)이었고, 스텐트 삽입부의 경우는 인체 0.54(±0.004), 동물 0.59(±0.011), 팬텀 0.04(±0.007)이었다. 기관 분지부가 이루는 각도는 인체의 좌기관지에서 42.6(±2.07)˚, 우기관지에시 32.8(±2.77)˚이었으며, 동물에서 각각 43.4(±2.40)˚, 34.6(±1.94)˚, 팬텀에서 각각 35(±2.00)˚, 50.2(±1.30)˚이었다. 본 연구팀이 제작한 기관-기관지 팬텀은 기관지 스텐트 삽입술의 재현이 가능하여 중재시술의 술기연습용이나 스텐트를 평가하기 위한 체외실험에 사용이 가능할 것으로 사료된다. To evaluate usefulness of a functional tracheobronchial phantom for interventional procedure. The functional phantom was made as a actual size with human normal anatomy used silicone and a paper clay mold. A tracheobronchial-shape clay mold was placed inside a square box and liquid silicone was poured. After the silicone was formed, the clay was removed. We measured film density and tracheobronchial angle at the human, animal and phantom, respectively. The film density of trachea part were O.76(±O.O11) in human, O.97(±O.015) in animal, O.45(±O.O16) in phantom. The tracheobronchial bifurcation part measured O.51(±O.OO6) in human, O.65(±O.OO5) in animal, O.65(±O.008) in phantom. The right bronchus part measured O.14(±0.008) in human, O.59(±0.014) in animal and O.O4(±O.OO7) in phantom. The left bronchus were O.54(±O.004) in human, O.54 (±0.008) in animal and O.08(±0.008) in phantom. At the stent part were O.54(±O.004) in human, O.59(±0.011) in animal and O.04(±0.007) in phantom, respectively. The tracheobronchial angle of the left bronchus site were 42.6(± 2.07)˚ in human, 43.4(±2.4O)˚ in animal and 35(±2.00)˚ in phantom, respectively. The right bronchus site were 32.8(±2.77)˚ in human, 34.6(±1.94)˚ in animal and 50.2(±1.30)˚ in phantom, respectively. The phantom was useful for in-vitro testing of tracheobronchial interventional procedure, since it was easy to reproduce.

      • 行政改革의 主要變數와 發展戰略

        李光鍾 청주대학교 행정문제연구소 1984 행정학논집 Vol.5 No.-

        In this paper, the writer has discussed the following dimensions on administrative reform. (1) The definition and some processes of administrative reform. (2) Environment and administrative system. (3) The objectives and main variables of administrative reform. (4) Strategy for administrative reform. Administrative reform is a continuous activity that takes place in such varied circumstance and, therefore, meaningful generalization is difficult. The demand for reform of public administration arises from the malfunctioning of the natural processes of administrative change. Generally speaking, movements of reform begin with the intention of removing obstacles to change or of improving on the results of change where it is being accommodated. Administrative reform is the artificial inducement of administrative transformation, against resistance. Administrative reform is articifial, strategic for the betterment of efficient performance because it is man-made, deliberate, planned; it is not natural, accidental or automatic. Administrative reform is deliberately abstracted from its surroundings to concentrate on the specific stages that reformers experience in their esseneially political struggle to change existing behavior patterns and functional tasks in administrative system.

      • 農村開發과 行政戰略

        李光鍾 淸州大學校 1981 論文集 Vol.14 No.1

        The object of this paper has been to explore the choice of policies with a view to establishing the administrative strategy on the development of rural areas. The above-mentioned contents can be regarded as the characteristics arisen from the process of implementing actual activity for rural community development. Generally speaking, The following characteristics have been observed throughout the Korean rural community. (1) The Community suffers from the decreasing of population and man-power. (2) In personal living standards and the level of income rural areas are not much improved. (3) We can grasp the lower level of agricultural mechanization and the small-sized farming. (4) As propelling of the new community movement inhabitant's consciousness and creativity is much elevated. Samaul leaders tend to be future, development oriented, educated, and committed to evironmental change. The traditional inhabitants tend to be rural, oriented to local customs and to the indigenous religion, and opposed to change. The author has suggested the fundamental administrative strategy for the improvement of common living standards, income and environment in the rural areas. Chapter Ⅱ described the results of research carried out within rural areas. Chapter Ⅲ has attempted to illustrate the theoretical model of administrative strategy and the interaction of variables. The administrative strategy for rural development can be summarized as follows. (1) The Strategy for development should be correspond to new situation. (2) Rural development should be performed in the direction of enhancing agricultural production and productivity. (3) To this end, the objective environment surrounding rural areas is to be examined, that environment was described as a set of developmental facfors, each leading to definite anticipated effectiveness. In some cases, we can identify certain influence from the social, economic, or political environments that shape administrative strategies. (4) To perpetuate effective development the government should implement the education of knowledge, value, and technology. (5) Administrative strategies should be performed on the basis to overcome all limited resources: (ex, manpower, public facilities, knowledge, technology etc) (6) The government will have to induce a voluntary initiative of inhabitants. The ultimate aim of rural community development is to discover the betterment of common living standards and environment, although in practice these aims are of course only imperfectly attained. Therefore, the author thinks that the authorities concerned with the rural community development should cooperate to the achievement of the above-mentioned aims and explore every new possibilty of development alternatives. In short, public administion for rural development refers to the processes of guiding a strategy toward the achievement of progressive objectives that are authoritatively or voluntarily determined.

      • 行政責任의 性質과 基準

        李光鐘 청주대학교 사회과학연구소 1989 한국사회과학연구 Vol.8 No.-

        The purpose of this paper is mainly to study the characteristics of responsiblity and its criteria in public administration. As the people's demand for the administration continue to increase, The administration is in a position to play a role deeply related to pelple's rights and interests. The contents of administration become complicated, specialized and techniclized in modern administrative strates. In many cases, the need of discretion power has been recognized in public administration to deal effectively with most administrative affairs. The stronger and the more concentrated the power of administrative discretion, the greater the misuse of its power. So adminiistrative responsibility become more important. Some characteristics in the Administrative responsibility are as follows. First Administrative responsibility is discussed and evaluated on the precondition of given obligation and discretion of administrators. Second, Most propriety in administrative responsibility depend upon our resonable understanding of the problems of cause and effect. Thired, A responsible administrator should carry out the public interest. Scholars have emphasized various criteria of administrative responsibility in democratic countries, but people-focused responsibility is on major goal of public administration. It is necessary for administrators to investigate and recognize the priority or the different weight among the criteria of responsibility sush as the effectiveness, the efficiency, the responsiveness, Social equity, citizen's participation and people's benefits in public administration.
