        박영철 한국체육대학교 1997 敎養敎育硏究所 論文集 Vol.- No.2

        Now, there is the cherished of the whole of the Korean people for peaceful reunification. Up to the present, a number of specialists and scholars hane studied and analyzed it in each field of study. The problem of reunification is in confusion because of the abstracrt and uncertain affitude for reunification. The problem of reunification should be understood and settle on the basis of real conditions and Government should have strong will and work out the measures for reunification. It is essential to remove the hostility toward each other and change our consciousness and affitude. It os the most urgent business to make peace on the basis of humanism including the philosophy and secunty of human dignity. Above all, Reunification of North and South can be accomplished only when domestic politics is stabilized and national harmony and unith is formed without trouble between the Government and political parties.

      • 새로운 패러다임 형성과 안전사고에 대한 고찰

        박영철 한국체육대학교 2000 敎養敎育硏究所 論文集 Vol.- No.5

        An important thing than clsc amid of opening toward the 21st Century is to restructure consciousness of the people, the sense of value, and to reform spiritual will, Foundation th develop human society on nowadays is mutual confidence the same as a country dominating the world in the ancient and modern society observing well all the systems and laws. Enjoying and posscssing human history and culture is possible only when based on this confidence. Nonexistence of mutual confidence among human beings brought about democracy not well exercised, unstable society, frequent occurrence of small and large scale accidents, and unestablished political view. I Think that the only way to solve this problems is to restructure the sense of value to realize community consciousness and democratic society. We should focus on character building of adolescents to recover the sense of moral and morality existed in our traditional society. Seriousness of the problems prevailing in our society have caused unbalanced distribution, ideological discord, erroneous consciousness between generations, difference between urban and rural areas, and social tendency of destruct and egoism which have continued for a long time. It is our propriety as a nationality to observe the obligation and responsibility given to us in every sector and through this we will be able to achieve an ideal and goal of each individual, Most important thing of the life is to keep home well and in this case, my and my family's freedom, responsibility, and rights may not be infringed by others, and the laws are obligations as well as the will to observed mutually among human beings.

      • 틸트 로터형 무인항공기의 손상허용 설계

        박영철,임종빈,박정선,Park, Young Chul,Im, Jong Bin,Park, Jung Sun 항공우주시스템공학회 2007 항공우주시스템공학회지 Vol.1 No.2

        The Damage Tolerant Design is developed to help alleviate structural failure and cracking problems in aerospace structures. Recently, the Damage Tolerant Design is required and recommended for most of aircraft design. In this paper, the damage tolerant design is applied to tilt rotor UAV. First of all, the fatigue load spectrum for the tilt rotor UAV is developed and fatigue analysis is performed for the flaperon joint which has FCL (fatigue critical location). Tilt rotor UAV has two modes: helicopter mode when UAV is taking off and landing; fixed wing mode when the tilt rotor UAV is cruising. To make fatigue load spectrum, FELIX is used for helicopter mode. TWIST is used for fixed wing mode. Fatigue analysis of flaperon joint is performed using fatigue load spectrum. E-N curve approach is used for picking crack initiation point. The LEFM(Linear Elastic Fracture Method) is considered for analyzing crack growth or propagation. Finally, including the crack initiation and propagation, the fatigue life is evaluated. Therefore the Damage Tolerant Design can be done.

      • 하자 개념과 영조물하자설 : 일본의 입법중심으로 On the basis of Japanese Legislation

        朴永徹 韓國體育大學校 1993 論文集 Vol.16 No.-

        Judging from the fact mentioned above expecially, scholars of administrative of Japan stand on their opinion theories and precedents have not definite and clear regulations on national liability of reparation. And, in this manuscript, The dominant view is that a objective view is regarded on a prevalent view, on the other hand a subjective view and a compromise on conflicting views is regarded as being assimilated into the view of contravention of a obiligation. As mentioned above, most of all the countries investigated to approve a objective view. It is a very lucky to protect national fundamental rights and it is thought that such system have to be enforced widely. Therefore, Further studies and much efforts are essential to positively protect salvation of a victim. If we study and examine the national responsible system diversified ways and compare with the systems of other countries, We'll gain better national compensation law. Adding a remark Judging from developing process of administrative law, an invasion of constitutional rights by administrative act have not to be and relief method of that also have to be legal and rational. And I hope that range of that relief is protected further widely.

        제 1 소구치 발치를 동반한 제 Ⅰ 급 치조성 양악 전돌 환자의 치료 전·후 비교에 관한 연구

        김형돈,박영철 대한치과교정학회 1994 대한치과교정학회지 Vol.24 No.1

        The purposes of present study were to evaluate changes in models and lateral cephalometric head films during orthodontic treatment and to compare the amount of incisal retraction and anterior movement of molars with the two approaches of the retraction method of canine(sectional canine retraction vs sliding canine retraction) and the anchorage management(head gears vs no head gears, transpalatal arches vs no transpalatal arches and relation arches vs no relation arches) and to evaluate changes during orthodontic treatment in models with relation to lateral cephalometric head films. 67 Korean women with Angle's Class Ⅰ bialveolar protrusion were selected, whose initial chronologic age was above 16 yrs. Models and lateral cephalometric head films were taken before and after orthodontic treatment with four bicuspid extraction, the results were obtained as follows : 1. Significant decreases were observed in intermolar width, arch length and arch perimeter of maxilla and mandible but significant difference was not observed in intercanine width of maxilla and mandible during treatment period. 2. The linear change of the upper incisor to upper lip was 2.84:1 and the linear change of the lower incisor to lower lip was 1.45:1. 3. There were no significant differences between the two groups(sectional canine retractions vs sliding canine retractions), the two groups(transpalatal arches vs no transpalatal arches) and the two groups(lingual arches vs no lingual arches) in the amount of incisal retraction and anterior movement of molars. There were a greater amount of maxillary incisal retraction and a lesser amount of anterior movement of maxillary molars with the use of head gears than no use of head gears. 4. Changes during orthodontic treatment in models with relation to lateral cephalometric head films were obtained as follows : 1) Maxilla Central incisors were moved 3.79㎜ backward, canines were 0.22㎜ laterally and 3.70㎜ backward, and molars were moved 0.535㎜ medially and 2.29㎜ forward. 2) Mandible Central incisors were moved 3.04㎜ backward, canines were 0.145㎜ laterally and 3.92㎜ backward, and molars were moved 0.755㎜ medially and 1.17㎜ forward.

        측모 두부 방사선사진과 컴퓨터 영상사진(Dolphin Imaging System)의 계측치에 관한 비교

        박해준,박영철 대한치과교정학회 1994 대한치과교정학회지 Vol.24 No.3

        The purpose of this study was to compare the differences in measurements between cephalometric radiographs and digigraphs of Dolphin Imaging System. 26 Korean adult male and 24 adult female with normal occlusion were selected. For each subject lateral cephalogram was taken. Digitizing with Digigraph Work Station of Dolphin Imaging System. was performed as well. 50 tracings and 50 digigraphs were analyzed with Yonsei, Ricketts, Burstone analyses. The comparable measurements between tracing group and digigraph group were statistically analyzed. The results were as follows : 1. 13 of 64 comparable measurements did not show any statistically significant difference (P>0.05) between tracing group and digigraph group. 2. Three of the measurements with FH plane as a reference plane did not show any statistically insignificant difference. All measurements with SN plane as a reference plane showed statistically significant difference(p<0.05). 3. The measurements which showhed no statistically significant difference were mostly short distance linear measurements while most of the angular measurements showed statistically significant difference(p<0.05).
