An athlete must train his body and practice image training on an everyday basis in order to keep his competitive power in sports games and to improve it. This study is focused on the concept and theory of image training and its characteristics and actual effect along with the relevant case studies. Also, through thorough observations, the optimal psychological preparation for athletes to increase their competitive power in sports games was comprehensively studied. For image training to take effect and lead to the improvement in competitive power, both athletes and instructors should always try to find out ways to practice image training in a theoretical way, while working out to find out a psychological preparation method for each of the athlete, with more comprehensive point of view. Meanwhile, those who are interested in the psychological preparations to improve competitive power of athletes might need to take into consideration that most of what have been studied here are based on the cases of western athletes and were founded on the basis of their culture, and try to work out to provide a foundation on which to build an image training and psychological preparation strategy for Korean athletes.

Traditional oriental medicines have ken used for tmament of various kinds of human cancers for long times and some of mem proven to k effective clinical-. However, the pItarmacologica1 actions ad mechanisms related to cancer treatment are generally unknown. In an effort to clarify the action mechanisms of several oriental medicines used for cancer treatments. we planned this experimental praedura. We selected Cadyceps sinensis (동충하초), Punellae Herba (夏柱草), Rehmanniae Radix (熟地黃), Paeoniae Radix (白均案), Oldedamar Herba (白花批告草), Partulaceae Herba (馬首算), Scdopendrasubspinipes mudans (蜈松), Mylabris Phalerara (班藝), Phellinus igniarius(蔡黃), Ganodermae Lignum(靈芝) for evaluation, which have ken used for patients of gastric cancers. The twenty grams of medicines were boiled in 100㎖ of water for 1 hour and filtered with O.2㎛ pore-sized filter unit to remove insoluble particles. Initially we evaluated the effects oriental medicines on growth inhibition in stomach cancer cells. The gastric cancer cell line, AGS, was cultured in RPMI l640 supplemented with lO% heat-inactivated fetal bovine serum and Heated with lO㎕ oriental medicines per l㎖ of medium up to 48 hours. The specimens were subjected to MTT assay for evaluation of growth inhibition. We found mat Mylabris piulema (班 察) markedly supmessed the growth of cancer cells as shown in results. Next, we checked the effects of orielntl medicines on cancer on cell cycles and apMonsis. Mylabrls phalerata (반모) inhibited cell cycle progression of Canea cells a compared with connol cells and cells treated with other medicines. In addition, Mylabri phalerata (반모) induced apptosis in 30-40% of stomch cancer cells within 24 hours. Other oriental medicines used for this experiments did not show apoptosis-inducing effects on cancer cells. Finally, we determined the expmSSion levels of genes associated with cell cycle Md apoptosis. The expressions of bcl-2 and bcl-XL were downregulated by the treamerm of Mylabris phalerata (반모). However, the expression levels of genes related to cell cycles were not altered significantly. In conclusion, we found that Mylams phalerata (반모) has in vivo gowth-inhibiting ad apptosis- inducing effects on stomach cancer cells. However, we think that at least animal experiments are necessay for evduations.

The purpose of this research is to look for the best description of calculating the reasonable Landing Fee. Landing Fee is consisted one of major revenues for maintaining an airport. Traditional Landing Fee Rate has been charged based on the weight factor; Maximum take-off weight, Maximum landing weight, or Maximum authorized weight. To achieve a better reliable value of Landing Fee Rate, The elements of Noise and Peak-Time have to be considered as well as the aircraft weight. This research designs the algorithms for calculating Landing Fee Rate and also Landing Fee, based on the aircraft weight. The Network is also applied to above. That is, CGI(Common Gate Interface) is constructed to interface the terminal of calculating Landing Fee Rate, and the terminal of collecting and transmitting the data such as the Weight. The computer language on the CGl was made by C++ and PERL. The main point of this research is to integrate the airport and Information System and to construct the database which is based on the different perspective of calculating Landing Fee Rate. However, the result of the most efficient and reliable will be computed based on above. This research will broaden the range of application up to the each case of airports.

발달장애학생을 위한 웹기반 의사소통능력신장 프로그램의 개발과 적용 사례

김동현,유영환,김좌중,천경철,이청용,김봉수 국립특수교육원 2005 연구보고서 Vol.- No.10

발달장애학생의 의사소통능력은 단순한 언어문제 이상의 의미를 지닌다. 의사소통능력은 모든 학습의 기초가 되고 결국 인간의 삶의 질을 좌우하게 하는 중요한 요소가 되고 있기 때문에 의사소통능력에 문제가 많은 발달장애학생에게 있어서 의사소통능력 신장은 매우 중요하다. 발달장애학생의 언어 및 의사소통능력의 결함은 사회적 결함과 인지적 결함에 상호 관련성이 있어 다른 사람으로부터의 의사소통을 이해하는 능력과 자신의 생각을 표현하는 능력이 제한되어 다른 사람과의 상호관계를 맺는데 어려움이 많았다. 따라서 발달장애학생의 언어지도는 생활 장면에서 교수하는 것이 가장 바람직하다고 하겠다. 그러나 지금까지 주로 활용된 전통적인 언어지도 방법은 어휘를 증가시키고, 발화의 길이를 널리는 데는 효과가 있었지만, 학습된 내용을 생활 장면에서의 일반화에는 문제점이 있는 것으로 지적되고 있다. 발달장애학생의 언어지도 방법은 일상생활 속에서 학습 내용을 선정하고 이를 실생활 장면 혹은 이와 유사한 환경에서 효과적으로 지도할 수 있는 적절한 교수 방법이 필요하다. 그래서 발달장애학생의 의사소통능력 신장을 위한 환경중심 언어지도 방법을 활용한 웹(Web)기반 언어지도 프로그램을 개발하였다. 웹(Web)기반 언어지도 프로그램은 제7차 특수학교 기본교육과정과 국립특수교육원에서 발간한 ‘발달장애학생의 언어교육 프로그램(1998)’ 분석을 통하여 개인 · 가정생활, 학교 · 사회생활, 경제 · 여가생활 등의 6개 영역으로 구분하여 각 영역별 학습주제를 선정하였으며, 학습주제에 대한 학습의 진행 형태는 학습목표, 낱말학습, 상황학습, 평가로 진행할 수 있도록 하였으나, 학습자의 현재 수행 능력을 고려하여 능력에 따른 진행의 절차를 학습자가 선택할 수 있게 하였다. 본 프로그램을 적용해본 결과 다음과 같은 교육적인 효과를 얻을 수 있었다. 첫째, 웹을 활용한 가상체험을 통하여 적극적이고 흥미 있는 참여를 유도하며, 학습자 중심의 주도적인 학습과 안내자, 촉진자로서의 교사의 역할을 통해 발달장애학생의 의사소통 능력을 신장시킬 수 있었다. 둘째, 교실에서 이루어지는 지금까지의 수업방식을 탈피하여 학습자가 언제, 어디서나, 누구든지 학습할 수 있는 열린 학습체제의 교육환경을 조성할 수 있었다. 셋째, 문자정보, 그래픽, 애니메이션, 사진, 음성, 비디오 등 다양한 형태의 정보가 상호대화 형식으로 활용되며, 수준별 반복학습을 실시함으로써 교수-학습 방법의 개선뿐만 아니라 양질의 수업을 진행하는데 도움을 줄 수 있었다. 본 프로그램을 활용한 언어지도가 발달장애학생의 의사소통능력 신장을 위한 최선의 방법이라고 말할 수는 없으며, 언어지도의 한 가지 방법이라고 말할 수 있다. 따라서 본 프로그램의 활용한 언어지도는 학교에서 교사가 학생의 능력과 흥미를 고려하여 지도한다면 발달장애 학생의 의사소통능력 신장에 많은 도움이 될 것이다. The developmental disability of the metal handicapped children means more than simple linguistic problem. The developmental disability is the base of all the learning and important factor which decides the happiness of the human being finally, so the extension of mutual understanding ability is so important, in the case of the metal handicapped children who have a problem of the mutual understanding ability. In the case of the metal handicapped children, the defects of the mutual understanding and linguistic ability are related with the social defect and the defect of recognition, and the ability of understanding about mutual relations with other people and self-expression ability are limited. So they have many problems in mutual relations with other people. Therefore, the linguistic instruction of the metal handicapped children is recommended to be done in the living. But, the traditional linguistic instruction which's used mainly as yet, is effective in increase of a vocabulary and the length of a locutionary act, but it has a problem in the popularization of the learning in the real life. The method of the linguistic instruction for the metal handicapped children, should be selected as contents in the real life, and the right learning method which can be done under the real life or the similar environment with it, is needed. Because of the above realities, the linguistic teaching web-based program is developed, using the linguistic instruction which is focused on the environment, for the extension of the mutual understanding ability of the metal handicapped children. In the linguistic teaching web-based program, it is divided with 6 field (personal · home life, school · social life, economical · leisure life) and the educational subject classified by each field is selected, by the analysis of 'The linguistic educational program for the children who have developmental disability' published by the 7th basic education course of special school and the national special education organization. Besides, the progress form of learning about the educational subject is directed by educational goal, word learning, situation learning and valuation, but a learner can choose a procedure followed by ability, regarding to his accomplishment ability. As the result of the application of this program, the educational effects that we could get are the following : 1. We could lead a positive and interesting participation by virtual experience through WEB, and the communication ability of the metal handicapped children was extended by a role of a teacher, as a guide and promoter and a leading learning focused on a learner. 2. The teaching method which is done in school now, is dismissed and we could form the educational environment of the learning system that a learner could learn, without distinction of time, a place and a person. 3. The various form of information, like text, graphic, animation, photo, sound, video and so on, is applied as a form of communication. Therefore, the program was useful in not only the improvement of the teaching-learning method, but also the proceeding of the effective lesson. The linguistic teaching which use this program, can not be the best method of the extension of the mutual understanding ability and it's just one method of linguistic teaching. if the linguistic teaching which use this program is conducted, regarding to a ability and a interest of a student, it will be so useful in the extension of the mutual understanding ability, for the children who have developmental disability.

유봉구,곽강호,김태유,김광수,유경무 대한치매학회 2004 Dementia and Neurocognitive Disorders Vol.3 No.1

Cerebral amyloid angiopathy can cause intracerebral hemorrhage, progressive dementia, seizure and transient ischemic attacks. Dementia is a relatively common manifestation and associated with the presence of recurrent strokes and leukoencephalopathy. A 66-year-old right-handed man with hypertension and recurrent strokes presented with rapidly progressive dementia and sudden onset of dysarthria and dizziness. He showed memory impairment, personality and behavioral changes, and executive dysfunction for one and an half years. These symptoms developed insidiously and quite rapidly without fluctuation. Brain CT showed a small hemorrhage in the right cerebellum. Brain MRI, especially gradient-echo images revealed multiple cortical and cortico-subcortical microbleeds. Four weeks later, right hemiparesis suddenly developed and a repeated MRI showed a new left corona radiata infarction. We learn from this case that gradient-echo MR images should be performed in patients with rapidly progressive dementia and recurrent strokes.

반응성 스퍼터링에 의한 전극 및 산화박막에 관한연구

김봉열,전계석,유상록 연세대학교 산업기술연구소 1980 논문집 Vol.12 No.2

Thin films of AI and ITO were prepared by RF diode sputtering and also the thin films of AIN were deposited by rf reactive sputtering. And then, the deposition rate, electrical resistivity and spectral transmission of these flms were investigated. It is obvious from the results that the sputtering input rf power strongly influenc es deposition rate of AI and ITO thin films. On the average characteristics of ITO thin films, the electrical resistivity was 4∼6×10­⁴Ω-cm and spectral transmission was more than 80%. When the partial pressure of nitrogen in argon nitrogen mixtures was increased, the deposition rate of AIN films began to decrease drastically at nitrogen partial pressure 2∼3×10­³ Torr, presumably the electrical resistivity of films began to increase rapidly, at the same critical pressure of nitrogen.

국소침 윤마취시 Epinephrine 효과에 대한 관찰

金鳳謙,金容培,方裕鉉,朴種燮,柳在德 大韓成形外科學會 1983 Archives of Plastic Surgery Vol.10 No.1

The local anesthetics play a central and frundamental role, for they comprise, probably, the single most widely used group of durgs in the field of plastic surgery. Also many plastic surgical procedures require the use of a vasoconstrictor to reduce operative bleeding under both general and local anesthesia. Among local anesthetics, lidocaine, introduced by Lofgren in 1948, is one of most widely used local anesthetics and most frequently used for infiltration anesthesia with 0.5% to 1 0%solution. Also eqinephrine is one of the most potent and most useful vasoconstrictors for admixture with thesolution of local anesthetics for infiltration of tissue. In the clinical practice, it has been said that the concentration of lidocaine and epinephrine should be kept at the minimal level of effectiveness because of the epinephrine performs a dual service when is combined with lidocaine. In order to clarify the minimum concentration of the lidocaine and epinephrine respectively necessary for adequate duration of anesthesia, with less irritation of local tissue and less bleeding, the clinical observation and animal experiment were undertaken, and the following results were summarized. The most effective skin blanching by epinephrine was obtained with epinephrine concentration of 1 : 50,000 although some effect was still presented with epinephrine concentration of 1 : 800,000. The onset of maximum skin blanching following the local infiltration of lidocaine with epinephrine(1 : 50,000 to 1 : 400,000) was within 5 minutes and was lasting 20 to 40 minutes. When the skin incision was made 5 minutes to 15 minutes following local infiltration of epinephrine, the amount of bleeding was markedly decreased and no significant difference in the time of hemostasis was noticed(p〉0.1). Also no significant difference in the time of hemostasis was noticed in the different concentration (1 : 100,000 and 1 : 200,000) of epinephrine(p〉0.1). The optimum concentration of epinephrine is between 1 : 200,00 to 1 : 400,000 solution and the optimum concentration of lidocaine is 0.5%.

1. This thesis aims at analyzing the characteristics of the demarcation line of the administration areas in Korea by reviewing the history and background of how it was drawn and at the same time at exploring ways of correcting factors contributing to problems and ineffectiveness of administration. In order to collect data of opinions on this matter from officials actually assigned to the counties and their sub-level administration areas where administration is bifurcated in two separated blocks of areas, irrespective of the administrative efficiency and convenience of the populace in the areas, we selected eight kuns of this nature and sent questionaires to 488 chiefs and leading officials of kuns, myuns and villages. A total of 237 persons, 48.6% out of 488 responded. This data proved to be very expedient and instrumental in carrying out this study. 2. One of the characteristics of the demarcation line of administration areas is that it is drawn on the basis of natural conditions such as the extention of mountains, meandering lines of rivers, the formation of the community, traditional reasons, and so forth rather than on the theoretical as well practical backgrounds imbued with administrative philosophy, which seeks for rational and balanced development of a whole community with two factors in mind: the principle of spatial division as an administrative skill and the principle of spatial harmony for balanced division of administration zones. However, it is true that a large number of local inhabitants have felt inconveniences due to the boundary lines being zigzag or meandering. When we surveyed on the frequency of going to market as an indicator of economic activities of the people living along the boundary lines, it is found that almost 77.6% of the people questioned answered that they were going to markets located in the neighboring kun rather than those in their own administration zones. The factors that lead to choosing markets are usually two: one is spatial distance and the other is the peoples norm of life. Although the nature of the responses may vary according to where people live within the divided block of the administration area, a total of 86.6% of the questioned expressed their hope that the boundary lines would be straightened. This reflects their wishes of improving the efficiency of local administration and convenience of living for effectiveness of the administration cantrol. For example, state boundary lines of the U.S and Australia belong to the theoretical type is whereas sung boundary lines of China and kun(county) demarcation lines of Korea belong to the natural condition (or setting) type. Especially, some of administration demarcation lines of Korea have been zigzay so that one kun is divided into two or more separate blocks of areas as the result of city administration areas within the kun becoming enlarged. There are eight cases of this nature in Korea. 3. Our survey which was conducted to discover in part the extent of awareness of such bifurcation or division by the inhabitants living in the divided zones, showed that only 83.4% of those who responded said that they had knows the fact and the remaining 15.5% were quite unaware of the fact until they came to realize it upon reading our questionaire. This extent of unawareness means that local ranking administration leaders did not pay much attention to the effect of the local administration with respect to the boundary lines. 4. Speaking from the above finding, we are to propose that irrational factors related to the present administration demareation lines be corrected and improved for the following reasons: 1) To enhence the efficiency of administration, 2) To reestablish the system of utilization of resources 3) And finally to enlarge the integrated potentials of various social dynamics. We hope that efforts will be made to straighten administration demarcation lines as far as possible, taking into consideration the opinions and wishes of the people living in the affected areas and zones so that directions of development and improvement on this matter may be effectively explored. At the same time we propose the establishment of long range policies with a view of eliminating disparity in the development between the regions, by implementing necessary measures for development of local cities.
