      • 大學卒業定員制의 實施에 따른 學生生活 指導方案에 關한 硏究

        崔根爀,張忠根,李相祐,張鎭吉,張大熙 충남대학교 1982 學生生活硏究 Vol.10 No.1

        Higher education in Korea is faced with a new situation since 1981 when the government implemented a college graduation quota system designed to broaden the opportunities for higher education, alleviate the problem of the students who fail the entrance examination, and improve the quality of college graduates. The change of the system has brought about several serious problems including how to supply enough faculty members, how to provide enough educational facilities, and how to cope with the huge increase in the number of students, 30% more than graduation quota. The greatest single problem resulting from the implementation of college graduation quota system is the psychological and emotional unease aroused among the students, because 30% of those students with unsatisfying results must be banished from college before their graduation. This study aims to find effective measures for student guidance that each of the colleges can implement to help students adjust to the changed circumstances. After objectively investigating the problems from the various educational environments, from the recent students' views of college, and from the psychological and emotional unease arising in them by the fear of failing to graduate from their college because of implementation of the graduation quota system, a survey was conducted by means of a questionnaire composed of 40 questions and by means of personal interviews, 5,903 students, who are influenced by the graduation quota system, attending 19 public and private universities and colleges selected throughout the country. The data obtained from this survey were statistically processed with the help of the C. N. U. Computer Center, and the ratios of the responses to each of the questions were analyzed and calculated according to the distinctions of the total, sex, region, and major. The conclusions that the interrelations among the variant factors from each of the questions which were surveyed, analyzed and arranged have suggested are as follows : 1. The original purpose of graduation quota system should continually be clarified and communicated to all students and a concrete, specialized guidance system should be established to guide the minority of the students (13%) who don't fully understand the basic properties of higher educational institutions. 2. The institutions should provide enough educational facilities and supply enough faculty memebers to solve the problem of accomodating the large numbers of students. At the same time, they should suggest how students should learn positively and effectively to gain an expert knowledge, and how professors should gain public confidence in grade evaluation. Accompanying those measures, the government should develop a good policy to expand and distribute job opportunities to college graduates. 3. The admission quota should be controlled depending on the rate of naturally failed students, and then the students' unease and suppression caused by excessive competition can be relieved. In addition, it is advisable that the banished students should be allowed to transfer to University of the Air without regard to their grades. 4. An education devised to let students have a sound sense and way of thinking should be accompanied by a guidance system which their seniors, parents and society take part in. 5. An atmosphere conducive to sweet and well-rounded friendship among classmates should be created, sound extra-curricular activities should be encouraged and the number of students and adviser professor is in charge of should be lessened to a reasonable number.

      • 골다공증에 의한 압박 골절의 치료에 있어서 경피적 추세 성형술의 의의

        최재영,윤승환,조준,문창택,장상근 건국대학교 의과학연구소 2001 건국의과학학술지 Vol.11 No.-

        Percutaneous vertebroplasty has recently been introduced as a therapeutic alternative for the treatment of pain associated with osteoporotic compression fractures and performed popularly at a few centers by neurosurgeons. This technique allows marked pain relief through stabilization of microfractures and strengthening of weakened vertebral body. Authors retrospectively analyzed the clinical outcome of 100 patients with osteoporotic compression fractures for investigating the therapeutic effectiveness of percutaneous vertebroplasty. They were treated with vertebroplasty from April to August 1999. Plain X-ray of all patients showed osteoporotic compression fractures at more than one level.

        The main aim of this paper is to examine education expectation level of students majoring culture and tourism at universities in Korea. From the previous studies, Authors drew three general factors of educations of students (knowledge/humanity/ professional way). This study identifies the relation between three education factors mentioned and education environment of students(year/ sex/ major operation system). The data were collected from survey questionnaires on six universities for 3 month from late March to early July 2001. The empirical test is focused on discovering following points; - the efficiency of actual education operation system of universities - the differences of education expectation according to different academic year/ sex - the comparison of characteristics related to education expectation of university students

      • 모드해석에서의 경계조건 영향

        Modal analysis is a fundamental procedure to analyze the dynamic characteristics of structures or machines. Modal analysis is composed of theoretical modal analysis using finite element method and experimental modal analysis. The discrepancy between these two makes modal analysis difficult and ususally comes from misunderstandings on boundary conditions of the structure. Boundary condition effect in modal analysis is investigated theorectically and experimentally in this study for a rod and a beam. The result shows that boundary condition affects on lower modes, but can be ignored for higher modes. Boundary condition can be modeled by a spring and a damper having finite values. Using this spring and damper model, the boundary conditions of a theoretical modal analysis model can be corrected by comparing the results of experimental modal analysis.

        A mathematical model is formulated for the minimum cost design of reinforced concrete earth structures. The design variables are selected to be the depth and steel ratio in the retaining wall, and the depth, steel ratio and footing sizes in the isolated column footings. An elastic analysis is performed and resulting designs are based on both the ultimate strength theory and the elastic theory of concrete design. Constraint requirements are imposed to insure structural strength and side constraints. The resulting mathematical model is a nonlinear constrained optimization problem. The modified Lagrange Multiplier method is suggested as a satisfactory algorithm for the optimum design of the R.C. earth structures.

      • 나노 사이즈 TiO_2 광촉매를 이용한 페놀 분해

        최상근,김동주,김교선 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A

        In this study, we prepared nano-sized TiO2 particles for various process variables by the diffusion flame reactor and we collected TiO2 particles by thermophoresis. It is found that the size of TiO2 particles increases, as the flame temperature or the inlet TiCl4 concentration increase or the total gas flow rate decreases. We investigated the photo-degradation of phenol wish the prepared TiO2 particles. We found the optimum amounts of TiO2 photocatalysts for our experimental apparatus and investigated the photo-degradation efficiencies of phenol, changing the process variables such as size of TiO2 photocatlysts, phase ratio of rutile/anatase, concentration of phenol, input ratio of O2. Degradation efficiencies of phenol were almost 95% in 15 minutes for the standard conditions of our experiments.

        We prepared the nano-sized TiO_2 particles by the diffusion flame reactor and investigated the effects of several process variables on the generation and transport properties of TiO_2 particle. As the length from the tip of diffusion flame reactor increases, the size of TiO_2 particle increases by the coagulation between particles. The structure of TiO_2 particles prepared is almost found to be anatase. It was found that the TiO_2 particle size depends more largely on the change of reactor temperature than on the change of inlet TiCl_4 concentration.

        We prepared the nano-sized TiO_2 particles by the diffusion flame reactor and investigated the effects of several process variables on the generation and transport properties of TiO₂particle. As the length from the tip of diffusion flame reactor increases, the size of TiO_2 particle increases by the coagulation between particles. The structure of TiO_2 particles prepared is almost found to be anatase. It was found that the TiO_2 particle size depends more largely on the change of reactor temperature than on the change of inlet TiO_4 concentration. By the photo-degradation experiment of phenol and toluene with the prepared TiO_2 particles, we found that the photo-degradation efficiencies of phenol and toluene change, depending on the process variables such as size of TiO_2 photocatlysts, concentration of phenol or toluene. Degradation efficiencies of phenol and toluene was above 90% in our experiments in 60 minutes.
