최종환,김종식,최지민,신은혁,송기원,박영환,Choi, Jong-Hwan,Kim, Jong-Sik,Choi, Ji-Min,Shin, Eun-Hyuk,Song, Ki-Won,Park, Young-Hwan 대한방사선치료학회 2007 대한방사선치료학회지 Vol.19 No.1
Purpose: Total body irradiation is used to kill the total malignant cell and for immunosuppression component of preparatory regimens for bone-marrow restitution of patients. Beam spoiler is used to increase the dose to the superficial tissues. This paper finds the property of the distance between beam spoiler and patient. Materials and Methods: Set-up conditions are 6 MV-Xray, 300 MU, SAD = 400 cm, field size = $40{\times}40cm^2$. The parallel plate chamber located in surface, midpoint and exit of solid water phantom. The surface dose is measured while the distance between beam spoiler and patient is altered. Because it should be found proper distance. The solid water phantom is fixer and beam spoiler is moving. Results: Central dose of phantom is 10.7 cGy and exit dose is 6.7 cGy. In case of distance of 50 cm to 60 cm between beam spoiler and solid water phantom, incidence dose is $14.58{\sim}14.92cGy$. Therefore, The surface dose was measured $99.4{\sim}101%$ with got near most to the prescription dose. Conclusion: In clinical case, distance between beam spoiler and patient affect surface dose. If once $50{\sim}60cm$ of distance between beam spoiler and patient, surface dose of patient got near prescription dose. It would be taken distance between beam spoiler and patient into account in clinical therapy.

이 연구는 총련 문예동 소속 여성 시인들의 시를 인문지리학의 견지에서 살피고 있다. (신)문화지리학의 “보는 방식”(a way of seeing) 이론의 견지에서 그들 시가 ‘조국’을 경관화해 온 방식에 주목하고자 하였다. 그들 작품량이 많지 않은 관계로 조국의 지리학적 맥락이 분명이 펼쳐지는 부분을 중심으로 살폈다. 그들 무의식 층위를 분석하면 문예동의 일반 시인들이 그려온 ‘조국’ 지형이 일관된 것만은 아니었을 것이란 가설이 실제적으로 증명된다. 허옥녀와 강명숙의 시에 발현한 공화국의 지층은 그들 육친이 살아갔던 가정의 지층과 섞이기도 한다. 이 과정에서 그들의 독특한 조국-지리가 만들어지기도 했다. 주로 한으로 점철된 선친의 기억과 연계하면서 감성적 조국의 경관이 경험된 것이다. 그 기억에서 호출된 어머니는 ‘전사 어머니’ 위치로부터 풀려난 ‘죽은 어머니’, ‘엄마’, ‘딸’, ‘며느리’, ‘손녀’, ‘소녀’ 등으로 이동한다. 그것이 문예동의 것과는 다소 미세한 조국의 경관을 구성한다. 이 각 위치에서 나타난 조국은 그 상응 경관을 합성하면서 문예동의 관념화된 조국과는 다른 경관을 드러낸다. 때문에 이 두 시인에게 조국은 무오류의 공화국 공간으로만은 나타나지 않는다. 눈물로 가득하거나 시취(屍臭) 풍기는 공화국이 거기에 있다. 이 조국의 경관 속에는 일반적인 문예동 그룹에서는 1990년대까지 말하기 어려웠던 병고, 죽음 문제도 녹아 있다. 때때로 그들은 고독이 이는 자신의 가정 안으로 김일성이나 김정일의 얼굴까지 초대한다. 아울러 죽은 모친을 공화국의 목련 나무에서 피어나게도 했다. 이는 문예동 여성시인들이 그린 한반도 지도가 문예동의 지도를 예민하게 벗어나는 곳에서도 그려졌음을 지시한다. 이 시각은 지금까지 공간이나 지대 위주로 접근해 온 디아스포라문학 연구의 관성을 극복케 할 것으로 예상된다. This study examined the works of female poets belonging to the Chongryun “Munyedong” from the perspective of the (new) cultural geography. In particular, the manner their poems depicted their mother country was analyzed based on the theory of “a way of seeing.” Since there were a limited number of poems, the parts with a clear geographical personality were the focus of the examination. This analysis of the subconscious strata of poetry written by female Koreans living in Japan reveals the truth of their beliefs suggesting that the topography of their mother country outlined by the Munyedong group is not consistent. The poems of Heo Oknyeo and Kang Myungsuk show glimpses of a situation in which the stratum of the republic in which the leader exists mixes with the stratum of the family in which their blood relatives once lived to form a geography of the mother country. The geography of their mother country emerges as an emotional landscape of the motherland as it connects to the inner turmoil of their late father who was plagued with deep sorrowful resentment. The mother, summoned from memories, migrates from the position of ‘warrior mother’ to positions such as ‘departed mother’, ‘mother‘, ‘daughter’, ‘daughter-in-law’,‘ ’granddaughter’, and ‘girl’, and this allows the reader to experience a corresponding microscopic landscape of the mother country. The landscapes of the motherland presented from each of these posts are often complex. For the two poets, the mother country appears as a place filled with tears or as the face of a cosmos flower exuding the brilliant scent of corpses. Among these are included even the cries related to sickness and death, which the mainstream poets of the Munyedong found difficult to address until the 1990s. Furthermore, they invite the faces of Kim Il-Sung or Kim Jong-Il into the family where desolation would spread. This mingling of scenes portrayed the dead mother as a hortensia flower blooming from a magnolia tree in the republic. This is a case that “actualizes” the fact that the map of the Korean peninsula outlined by female Korean poets living in Japan was slightly different from the ideological map of the mother country drawn by the mainstream poets of the Munyedong. The human geography perspective of this research is expected to allow the study to go beyond the current inertia of diaspora literature that has approached the subject mainly through space or location

Ha, Jong-oh’s poem is beyond the simple diaspora literature since it shows that the situation of in-depth origins of the Republic of Korea is not much different than the surface through the vague voices of immigrant workers because even ethnic narrative related to the origin in ‘Trans space’ is questioned. In other words, it was shown that immigrant workers drawn by him are not the subjects welcomed in Korea as multi-cultural guests, but rather that self-evident ethnic origin is just the ‘flowing surface’ by separating the character of the state from the nation state, Republic of Korea. That is, their ‘external character’ rescales the Republic of Korea. The results of the study are as follows: First, he reveals through the gaze of immigrant workers who show ``curiosity`` about Korea that Korea is not a place only for Korean anymore but also a place which can be ‘used’ by occupiers. Second, this question was implemented as a cross-question about Korea``s National Ethics while comparing the lives of immigrant workers with the lives of animals. That was a question about globalism concerning manifold forms of violence, in other words, it was a question about the laws of Korea. Third, the poet knew that the national history of Korea was a place in conjunction with the ``transnational history`` of immigrants as a random narrative. If the first one was nothing but the nation’s rhetoric, the two were not opposing but related in parallel. That means that existing Korea was softened by setting Korea as a new space: through looking not at ``citizens / non-citizens``, but as ``occupiers``, he tries to set both histories as one joint ethic. Ha, Jong-oh’s poem is a ‘Trance Nation literature’ by trying to show that Korea’s ‘being Korea’ is not a matter of noble ethnicity, but consists of a ‘nation effect’. This new ‘sovereign place’, which has been used only by Koreans, is now used by ‘occupants’. This leads to global publicity which is the possibility of sovereign occupation of the immigrant workers and new publicity and universality.

The work to raise the bridge plate by using two hydraulic cylinders is very dangerous when generating the unbalance state between cylinders. For solving this problem, one cylinder is forced to follow the trajectory of another cylinder instead of applying the same trajectory to two cylinders at once. In this paper, the control method for dynamic stable on lifting the bridge plate is proposed. The simulation model is derived by using commercial software, AMESim and MatLab/simulink. The PID controller is designed on one cylinder for following the reference trajectory and the adaptive controller is designed on another cylinder for tracking the displacement of one cylinder. The performance improvement is shown by comparing the simulation results through computer simulation.

대학 교양 교과에서 에니어그램을 활용한 ‘자기탐색 글쓰기’ 지도 방법 연구
최종환(Choi Jong-Hwan) 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.19
이 연구의 목적은 글쓰기 수업에서 학습자 개개인이 자신의 내면을 예민하게 탐색하며 글을 쓰게 하는 교수학습 방법을 에니어그램(Enneagram) 심리프로그램과 연계하여 모색하는 것이다. 아울러 이렇게 설계한 교수학습기법이 자신과 세계에 대한 새로운 지식을 신장시키는 교양 글쓰기의 학습 목표에 기여하는 정도를 살피는 데 있다. 이 연구는 이와 관련된 글쓰기 교수학습방법론을 리소와 허드슨의 에니어그램 성격 유형론 등에 입각하여 설계하였다. 연구의 골자는 에니어그램 이론 전달 기법, 자기탐색 글쓰기 코칭법이다. 그 중 후자는 ‘은유 텍스트 변용하기’ ‘내면 아이에게 편지 쓰기’ 기법 위주로 제시된다. 에니어그램 프로그램은 글쓰기 학습자들의 내면을 개별 화해줌으로써 명징하게 만나게 한다. 자신의 성격 패턴을 비교적 정확히 인지하며 수행하는 글쓰기는 학습자 자기 탐색력을 신장시킬 수 있고, 교수자의 첨삭 시간을 절감시켜 줄 수 있게 된다. 이 점에서 에니어그램 연계 자기 탐색 글쓰기 지도 기법은 정의적 글쓰기 영역 수업을 활성화할 수 있을 것으로 예상된다. The purpose of this study is to find out the teaching and learning methods that enable individual learners to search and write their inner thoughts in writing class in connection with the Enneagram psychology program. The purpose of the second research is to see how the designed instructional technique contributes to the learning goal of the liberal writing which develops new knowledge about the student and the world. This study was designed based on Risso and Hudson s enneagram personality typology to develop the writing teaching and learning methodology related to this. The focus of the study is enneagram theory delivery technique, self - exploration writing coaching method. The latter is mainly focused on modifying metaphorical text and writing a letter to a inner-child technique. The enneagram program allows the students to meet clearly by personalizing the inside of the writing learners.Writing that perceives its own personality pattern relatively accurately can extend the learner self-search ability and reduce the time spent by the instructor. In this regard, it is expected that enneagram -related self- exploration writing instruction technique can activate class in emotional writing area.

대학 교양 교과에서 ‘가치관 더하기 빼기’ 기법의 가능성
최종환(Choi Jong-Hwan) 한국비평문학회 2017 批評文學 Vol.- No.64
본 연구에서는 대학의 교양 교과 영역에서 활용할 수 있는 ‘가치관 코칭’ 기법을 설계하고 있다. 이 기법은 수업 시간이나 생활 중 습득한 정보들을 ‘가치관 더하기 빼기’라는 연습 과정을 경유케 하여 자기 생각과 감정을 코칭하도록 돕는 테크닉이다. 이 연구는 이 코칭 테크닉을 수업 모형으로 구안하여 우리 교양 수업에 긍정적 효과를 파급할 것이라는 기대 하에 시도되었다. ‘가치관 더하기 빼기’ 기법은 학습자의 가치 순위들에 질서를 부여하는 연습을 도모케 함으로써 학습자 개인의 ‘가치 체계’에 일어나는 혼란을 정돈케 한다. 학습자들 간에 상충하는 배타적 가치정보들은 치열한 창의적 사고를 신장하는 이점은 있다. 그러나 개인의 가치관 내부의 상층부에 설치된 배타적 가치관들의 경우는 다르다. 이 후자의 가치관 갈등 및 그 수정 기술과 관련된 학계의 ‘구체적’ 관심이 아직 제기된 바 없다는 문제의식 속에서 이 연구가 수행되었다. 이 연구에서는 NLP 심리학 전문가 앤서니 라빈스의 NAC(Neuro-Associative Conditioning)에 기반한 가치관 인터뷰 방법 및 사례를 참조하고 이를 ‘가치관 더하기 빼기’라는 교수학습모형으로 구안하고 있으며 그것을 네 가지 단계로 구체화한다. In this study, ‘value coaching’ technique that can be utilized in the liberal arts curriculum area of university is being designed. The purpose of this study is to help learners organize and optimize his ideas and feelings in a consistent way through the ‘value plus subtraction’ technique. The ‘value plus subtraction’ technique developed by this research has the advantage of helping to prevent the confusion that arises in a ‘value system’ of a learner by arranging the order giving the learner’s value rankings. Conflicting exclusive value information between learners has the advantage of training fiercely debating thoughts, but it may confuse individual learners when working in a similar value chain. This study has been carried out in the context of the problem that there is no consciousness of the ‘concrete’ problem of academics or the educational system related to the value conflict and the modification technique that takes place within the individual learner. In this study, we refer to the methods and examples of NAC(Neuro-Associative Conditioning) and value interviews of NLP specialist Anthony Robbins and use it as a teaching-learning model of "value addition and subtraction". This technique is performed through four steps.
