朴亨夏,池三業,吳成基 釜山水産大學校 1992 論文集 Vol.47 No.-

The result of comparative group strudies on the nature and characteristics of Foot Reflexology using acupuncture as a health treatment to cure the diseases and aches in our body by stimulating a specific part or point of the body are as follows: 1) We can keep in good health by stimulating a specific part of our body. 2) Many neverous systems are concentrated in the foot more sensitive than the hand and it is possible to cure illness using them. 3) We can guess our state of Health from the state of development, and the structure, of our feet. 4) Park Jae-woo's foot theory forms a similar contracted corresponding system of body but in which the tip jount of the toe corresponds to our head. 5) Park's refexology claims that there exists a passage of energy blood which are linked to the blood vessels of body in a direct relationship to the contracted corresponding system enbodied in the feet. 6) Mildred Carter's approach is the structure of the contracted bowels of the body into the feet along with the right center line of the body, placing the right bowels into the right foot and vice versa. 7) Mildred Carter claims that the inside of the feet reflects the corresponding the backbone of the body. 8) Anna kaye's approach shows that two kinds of zones of the body, vertical and horizontal, correspond to these of the feet. 9) Takenouchi theory is a zone therapy which considers important the marginal scope of nerves transmitting in human body. 10) Bowling pin's reflexology is another interpretation of the contracted corresponding system of the foot laying stress on the torso.

敎育工學的面에서 본 英語敎育의 諸問題

朴炯基 釜山敎育大學 1967 부산교육대학 논문집 Vol.3 No.1

Although the educators of today are increasingly emphasizing the necessity of more scientific, modernized teaching-learning process, it seems that the conventional type of teaching and learning by means of text books, chalk, and blackboards alone is still in general use. In such a traditional type of classes, there prevails only the teacher-centered activities devised chiefly through the teacher's own experience and judgement. We can expect no scientific, effective instruction from such a traditional class. We must, at this occasion, develop the more scientific, effective, and economical teaching methods, which can be resulted only by the use of tapes, records, radio and television programs, and other audio-visual aids. This treatise deals with the various types of teaching machines in connection with effective methods of teaching English as a foreign language. Especial attention is paid to the audio materials such as tape recorders and language laboratories. Chapter one and two discuss the necessity of introducing educational technology into English langnage classes for varions reasons. Chapter three reviews and critisizes the existing problems involved in the modern English education, and suggests more effective means of teaching English by the use of audio-visual aids. The remaining chapters deal mainly with the more specific suggestions and problems in handling the individual mechanical devices such as phonographs, tape recorders, and language laboratories. These chapters also cover some aspects of educational problems of the radio and the television programs as teaching aids in English classes.

效率的인 英語學習指導를 爲한 韓·英兩語의 文法的 特質의 比較硏究

朴炯基 釜山敎育大學 1974 부산교육대학 논문집 Vol.10 No.1

In teaching and learning of English language, it has been our experience that there are patterns of English language that cause much difficulty in learning, and there are those that do not cause much difficulty. And it is the writer's assumption that through the systematic comparison of Korean and English languages we can easily discover and describe the difficult patterns that the Korean students will have in learning English. This study aims to compare some grammatical features of Korean language with those of English language in order to find out some fundamental problems for the Korean People in teaching and learning of English language. Before any of the questions of how to teach a foreign language must come the much more important preliminary work of finding the special problems arising out of any effort to develop a new set of language habits against a background of different native language habits. It is the writer's firm belief that the key of the achievement and progress in mastering English language lies in a careful systematic comparison of the descriptive structural analyses of Korean and English languages. The result of such comparison may surely prove of fundamental value for the preparation of more effetive teaching methods, teaching materials, and English learning experiments. The aims for a systematic comparison of these two languages are as follows: (1) Significance for Teaching and Learning Methods. It is generally assumed that Korean students who come in contact with English language will find some features of it quite easy and others extremely difficult. Those elements that are similar to Korean language will be, of course, simple for them, and those elements that are different will be difficult. The teacher who has been provided with the knowledge resulted by a comparion of English with Korean will be aware of what the real learning problems are and can better be equipped with effective teaching methods. (2) Significance for Teaching Materials. Modern English textbooks and supplementary materials should give due emphasis to those elements or features that are difficult because they are different from those of the native language of the students. Teaching and learning materials of English language should be graded as to grammatical structure, pronunciation, vocabulary, etc., giving priority to those features that are different from Korean language. And grading can be done best after the kind of comparison the writer is presenting in this study. (3) Significance for Research of the English Language. By using the results of linguitic comparison of Korean and English, we can pin point our research problems, and individuals can carry out highly significant experiments.

"Listening Approach" as an Effective Method of Teaching and Learning English

朴炯基 釜山大學校 師範大學 1978 교사교육연구 Vol.5 No.1

現代 外國語敎育에 있어서 外國語를 文學作品의 讀解手段으로서만 보다도 實際的인 communication의 手段으로서 가르치고 배워야한다는 主張을 否認할 사람은 別로 없을 것이다. 그러나 大部分의 사람들은 communication 이란 hearing 을 除外한 speaking 만을 意味하는 것으로 잘못알고 있는 것이 事實이다. 聽取面을 소홀히 生覺하는 理由의 하나로서 "eye gate"만을 重視하고 "ear gate"를 輕視하는 敎育的 偏見을 들 수 있다. 이와 같은 한 例로서 現在 우리나라 外國語敎育界에서 audio-lingual approach 가 크게 歡迎받는 敎授法으로 登場하고 있지만 이 方法은 production(speaking)에만 重点을 두고 있을뿐, listening에 對해서는 別다른 힘을 기울이지 않은 方法이라는 点을 들 수 있다. 筆者는 本論에서 效果的인 英語 學習指導의 한 方法으로서의 "listening approach"의 必要性과 有效生을 理論的 및 實際的인 次元에서 考察하였다. communication은 적어도 두사람 以上의 關與가 있어야하는 言語的인 process로서 한 사람이 發話한 內容을 listening 해 주는 쪽이 없으면 意圖했던 communication은 成立하지 못하고 만다. 따라서 言語能力에는 言語를 받아들이는.受容力 卽 listening이나 reading이 再生力 卽 speaking 이나 writing에 先行하는 것이 보다 合理的인 過程이라고 말할 수 있다. 그런데 우리의 言語活動에 있어서 全體 communication의 90%는 listening이나 speaking의 形態를 取하는바 이 두가지 skill 中에서도 特히 listening의 比重이 커서 普通 우리가 speaking에 1分을 보내는데 對해서 1.5分의 比率로 우리는 listening쪽에 더 많은 時間을 보내고 있는 것이다. 現代技術의 動向이 速度가 느린 print 形式에 依한 情報傳達方式보다도 速度가 빠르고 簡單한 sound 에 依한 傳達方式쪽으로 가고 있다는 点도 listening을 重視해야 한다는 理論을 뒷받침하는 것이 된다. 또한 先天的인 身體障碍로 發話機能을 喪失한 어린이는 speaking은 不能이지만 listening은 배울 수 있는 反面 聽取機能을 喪失한 어린이 卽 完全히 귀머거리가 된 어린이는 listening은 勿論 speak-ing 도 제대로 배울수 없다는 實例를 우리는 많이 볼 수 있다. 卽 發話障碍는 speaking 不能의 原因만 되고 listening 不能의 原因은 되지 않지만 聽覺障碍는 listening 不能뿐만 아니라 speaking 不能의 原因도 된다는 点으로 보아 listening은 speaking의 基礎도된다는 것을 알 수 있다. 어린이는 母國語를 배우는 過程에서 speaking을 試圖하기도 前에 이미 相當한 listening의 經驗을 가지고 있으며 꽤 複雜한 形態의 listening 도 可能한 것이다. 따라서 言語學習의 初期에 있어서는 speaking 보다도 listening을 먼저 導入하는 것이 바람직하다. 이와 反對로 listening 보다도 speaking을 먼저 導人하게 되면 不正確한 發音이나 잘못된 文去操作 等이 習慣化되어 오히려 言語發展에 不利한 結果를 가져올 수도 있다. 言語習得過程에서 listening만 一旦基礎가 이루어지면 speaking을 비롯한 그밖의 skill 은 보다 빠르고 正確하고 容易하게익혀진다. 指導의 實際에 있어서는 무엇보다도 學生들에게 listening 機會를 많이 提供해야한다. 敎師는 可及的 英語를 많이 使用하여야하며 어느 程度 listening의 基礎가 이루어지면 言語實驗室, 音響圖書室 等을 充分히 活用하는 한편 個人別로 錄音 tape에 依한 聽取機會를 豊富하게 갖도록 指導한다. 敎材의 內容은 敎室外的인 實地 situation에서 산 敎材를 뽑아오는 것이 理想的이기 때문에 TV나 radio program, 연극, 영화, 外國人 講師의 招請 等의 source를 充分히 利用한다. 그리고 ㅡ旦習得한 內容은 無數한 反複學習을 通해서 定着시킨다. listening 이야말로 數많은 signal이 무서운 速度로 한꺼번에 닥쳐오는 것을 꼭 같이 빠른 速度로 control 해야 하기 때문에 listening을 제대로 한다는 것이 學習者들에게는 가장 큰 關門인 것이다. 이러한 어려움은 오직 habit에 依해서만 克服될 수 있고 habit 形成은 反複學習에 依해서만 可能하다. ㅡ且 聽取訓練이 잘되어 listening의 基礎가 이루어지면 speaking, reading, writing 等의 다른 skills도 보다 容易하게, 正確하게 有效하게 達求된다는 것을 筆者는 主張한다.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

IMS 시스템을 위한 미들웨어의 연구

김형중,박태열,김기택 강원대학교 석재복합신소재제품연구센터 1998 석재연 논문집 Vol.3 No.-

지능생산시스템은 분산화되고 Fieldbus, LAN 등의 지역통신망과 ATM, 인터넷 등의 광역통신망도 이용한다. 서로 다른 오퍼레이팅 시스템과 다양한 통신 프로토콜을 사용할 경우 지능생산시스템에 요구되는 중요한 기능 중 하나가 플랫폼 독립 특성이다. 이런 요구를 만족하기 위하여 특별한 규약을 따를 필요가 있으며 이러한 규약에는 OMG(Object Management Group)에서 규정한 CORBA(Common Object Request Broker Architecture)가 있다. 본 연구에서는 Orbix와 Visual C++을 이용하여 IMS에 적합한 소프트웨어 환경인 생산 셀과 지능생산시스템을 모의하는 소프트웨어를 구현하였다. IMS 시스템을 CORBA로 통합하기 위하여 Orbix를 PC 환경에서 IDL(Interface Description Language) 언어로 작성하고 이를 Visual C++을 이용하여 시스템을 구성하였다. IMS(Intelligent Manufacturing System) can be characterized by a distributed manufacturing system based on local or wide area networks such as fieldbus, ATM, and the internet. Most important characteristics required are platform-independent and interoperable between different operating systems and/or communication protocols. CORBA suggested by OMG can meet the requirements. In this study, software programs using Orbix IDL and Visual C++ on PC environment are implemented, which simulate manufacturing cells and IMS.

효율적인 컴포넌트 개발을 위한 확장 객체지향 분석 및 설계

왕기철,박경우,고형대 木浦大學校 情報産業硏究所 1999 情報産業硏究誌 Vol.7 No.-

Component Based Development(CBD) is an emerging paradigm of software development. Its goal is composing an application with plug & play software components on the frameworks. This CBD requires existing software analysis and design approaches to be reconsidered. In this paper. we present the extended method from Object-Oriented Analysis and Design. To provide a clear separation of component specification form its design and implementation. we add interface design step and component implementation design step to the process of Object-Oriented Methodology. To provide a method of tracking each step in the development process, we add "use case-behavior-control object-interface mapping table", "component-interface-implementation class mapping table", and "interface-implementation class-integrated implementation class mapping table" to the Object-Oriented Models. Object-Oriented Models could be easily re-engineered to Component System Models by the proposed method. Component System Models also could be easily back tracked by the proposed method.

Essential thrombocythemia is a chronic myeloproliferative disorder of unknown origin, charcterized by excessive number of morphologically and functionally abnormal platelet in peripheral blood and abnormal proliferation of megakaryocytes in bone marrow. Its main clinical manifestations are hemorrhages and thromboses. The aim of therapy is suppression of the excessive bone marrow activity, which can be achieved by radioactive phosphorus, alkylating agent, hydroxyurea and interferon. Two cases were diagnosed at our hospital which had laboratory and clinical features compatible with this disease. We have successfully treated patient with hydroxyurea and platelet antiaggregating agent.
