[논문]훗설의 “기하학의 기원” 을 통해 살펴본 건축에서의 전통의 재활성화에 관한 연구

이길주,이동언 釜山大學校生産技術硏究所 2003 生産技術硏究所論文集 Vol.62 No.-

이 연구의 목적은 전통의 재활성화의 진정한 의미를 탐구하기 위한 것이다. 연구의 이론적 틀인 훗셜의 「기하학의 기원」은 근원에 대한 되물음을 통해 전통의 문제를 해명하고 있다. 전통의 재현과 재활성화는 전통의 수동적 이해와 능동적 이해에 의해 구별될 수 있는데, 전통의 재활성화는 능동적 이해를 통해 그 근원이 생활세계임을 이해하고,현시대 맞게 새로운 방식으로 전통을 재창조하는 것이다. 전통의 근원인 생활세계는 일상성의 재활성화의 바탕이 되는 세계로,사회 구성원들의 공통의 경험을 간직하고 있다. 그러나 일상적이고 습관적인 일상성이 재활성화될 수 있는 것은 의식의 지향성에 의해 새롭고 간-주관적으로 인식될 수 있기 때문이다.

The purpose of this study was to investigate the effects of STAD cooperative learning on student's cognitive(english academic achivement) and affective domain and to provide basic material which cooperative learning can apply to teaching learning activity. The research questions were as follows. 1. Is there any difference in cognitive(english academic achievement) between STAD cooperative learning group[EG] and traditional learning group[CG]? 2. Is there any difference in affective domain(sense of self-esteem, learning attitude, friend relationship) between STAD cooperative learning group[EG] and traditional learning group[CG]? First grade were selected (EG; 30, CG; 30) in middle school located at Chonju city. Previous survey(english academic achievement, sense of self-esteem, learning attitude, friend relationship) was carried out and the result between selected schools were alike. The instruments for this study were sense of self-esteem, learning attitude, friend relationship questionnaire and academic achievement toward english subject. Statistical analysis was performed by ANOVA. The major findings of the study were as follows: 1. There was a significant difference between EG and CG, namely, the experimental group was higher than the control group in academic achievement toward english subject. 2. There was a significant difference between EG and CG. In other word, the experimental group was positive than the control group in sense of self-esteem, learning attitude, friend relationship. In sum up, the cooperative learning situation was effective than traditional learning situation on student's cognitive and affective domain, therefore, the STAD cooperative learning should be considered as a teaching·learning strategy for the development of student's cognitive and affective domain[sense of self-esteem, learning attitude, friend relationship].

윤길수,김동준 釜山水産大學校 1985 釜山水産大學 硏究報告 Vol.25 No.2

본 연구의 결과를 요약하면 다음과 같다. 1. 복소수를 포함하는 선형연립방정식을 푸는 한 방법으로서 부분행렬과 Choleski의 직접해법을 이용한 새로운 프로그람을 작성하였다. 2. 복소수가 정의되지 않는 개인용 전산기에서도 복소수를 포함한 선행연립방정식을 풀 수 있다. 3. 부유체의 운동해석 과정 중에서 2차원 유체력을 구하는 부분에 본 계산방법을 이용할 경우 기억공간이나 계산시간이 줄어들게 된다. 4. 부유체의 운동방정식의 해법에 본 계산방법을 이용할 경우 계산과정이 간단해지게 된다. 5. 본 계산방법은 Gauss 소거법과 비교할 때 기억공간이나 계산시간이 적게 요구된다. This paper presents an application method of personal computer for the motion analysis of Floating Bodies. For the solution of linear equations with complex coefficients, a new computational procedure is formulated and programmed using partitioning and Choleski decomposition. The method is implemented in the personal computer which can not define complex variables. From the case study, it is found that the method is efficient in the motion analysis of floating bodies, especially in the calculation of 2nd hydrodynamic coefficients. Comparison with the Gauss elimination method shows that the proposed new method requires small memory size less computing time.

Using conventional textile techniques such as weaving, braiding, knitting and stitching it is possible to produce a wide range two and three dimensional fiber preforms. However, so far only a limited attention has been given to knitted fabrics in composite industry. This is mainly due to the opinion that knitted fabric reinforced composites posses low mechanical properties owing to their looped fiber architecture. But it is possible to obtain desired mechanical properties by selecting proper knitted fabric structure. In this paper, tensile failure load and displacement of one yarn, four yarns and knitted fabrics of ten yarns of kevlar fiber were determined experimentally in the unidirection. Mechanical properties of plain weft knitted fabrics reinforced composite intrusion beam for car side door application were investigated experimentally, which compared with desire value of American Fedral Motor vehicles Safety Standard (FMVSS) and presented the results.

Lolita에 나타난 세 목소리

이길동 현대영미어문학회 2000 현대영미어문학 Vol.17 No.2

There is no denying Nabokov must be an experimental stylist, for his novels such as Pale Fire, Transparent Things and Lolita are well known for their peculiar narration. Since the publication of Lolita, Many critics gave his novels various reviews, which are too variated to be categorized into one sect. In the case of Lolita they don't agree what kind of novel Lolita is. Some say it is a modem style novel. Others comment it is of the post-modern style. One commentator says it is a pornographic novel. Above all their criticisms are monolithic. It is very difficult to understand Lolita in such simple ways. Lolita begins with a very shocking story: Humbert, 37 years odd, has a sexual re1ationship with his step-daughter, Lolita who is 12 years old. The relationship begins after his wife's death. However, readers grow used to this shocking story while reading, for Nabokov uses various literary devices such as allusion, pun and parody in a strategy of 'defamilization' which is associated with Russian Formalism. In the novel, the character Lolita becomes the character Annabel Lee from Edgar Allen Poe's work and the character Carman from Meremee's work, which means Lolita is not real but imaginary character created through allusion, a part of parody. The frequent use of pun also achieves the effect of 'defamilization'. Father, the frequent intrusion of author undermines the reality of the novel. The 'work-within-a-work' style or 'chinese box' structure also serves in the same manner. These formalistic techniques reveals two tendencies, the first is that the methods help create artifiality of the novel, which means the absence of reality. The other is that the Russian formalistic literary devices, especially the 'defamilization' undermine the intensity of the shock in the story. Nabokov plays a game with the readers , Humbert makes Lolita an illusionary figure, which makes readers feel comfortable because they think the story is not true. But readers again believe in the reality of the story. Humbert kills Quility because he feels Quility is more evil than he. Humbert feels Quility has taken advantage of Humbert's sin. Readers feel in this scene Humbert actually kills himself because they are double.(297) In the last chapter, Humbert becomes a different figure, he achieves true development. He realizes Lolita is no longer a nymphet, and he comes to know that the hopelessly poignant thing was not Lolita's absence from his side, but the absence of her voice from that concord. Therefore, I hold that Lolita is neither post-modern nor modern, nor realistic but an open novel in which all 'sm' swim free.

Al5083-O 용접부의 보호가스 혼합비율에 따른 저온 인성 평가

이동길,이상열,양훈승,정재강 朝鮮大學校 機械技術硏究所 2002 機械技術硏究 Vol.5 No.1

본 연구에서는 저온용기 등에 많이 사용되고 있는 알루미늄 합금 A15083-O재에 대한 보호가스 혼합비율과 저온인성과의 관계를 규명하고자 혼합가스 비율을 여러 가지로 달리 하여 GMA 용접을 하였다. 시험온도는 상온에서 극저온까지 단계적으로 낮추어가며 계장화 샬피충격시험을 실시하였다. 최대하중은 시험온도가 낮아질수록 증가하였으나 변위는 25℃부터 -85℃까지는 시험온도에 관계가 없었으나 -196℃에서는 크게 감소하였으며, 모든 시험온도 및 불활성가스 혼합비율에서 흡수에너지는 용착금속부, 용융선 및 HAZ 순으로 증가하였다. 용착금속부의 흡수에너지는 시험온도 및 불활성가스 혼합비율에 관계없이 매우 낮게 나타난 반면, 용융선 및 HAZ시험편의 흡수에너지는 모재와 거의 유사한 값을 나타내었다. 또한, 모든 시험온도에서 흡수에너지는 He의 혼합량이 증가할수록 증가하는 경향을 보여 Ar33%+He67%에서 가장 우수한 인성을 나타내었다. In this study, the low temperature toughness was evaluated by using the instrumented Charpy impact testing procedures for A15083-O aluminum alloy used in the LNG carrying and storing tank. The specimens were GMA(Gas Metal Arc) welded with four different mixing shield gas ratios (Ar100% + He0%, Ar67%+He33%, Ar50%+He50%, and Ar33%+He67%), and tested at four different temperatures(+25, -30, -85, and -196℃) in order to investigate the influence of the mixing shielding gas ratio and the low temperature. The specimens were divided into base metal, weld metal, fusion line, and HAZ specimen according to the notch position. From experiment, the maximum load was increased a little up to -85℃, and the maximum load and maximum displacement were shown the highest and the lowest at -196℃ than the test temperatures because of the brittle behavior. The absorption energy of weld metal notched specimens was not nearly depends on test temperature and mixing shield gas ratio because the casting structure was formed in weld metal zone by melting welding wire. In the other hand, the others specimens was shown that the lower temperature, the higher absorption energy slightly up to -85℃ but the energy was decreased so much at -196℃.

치아의 발육 및 맹출에 따른 신경지배의 발달

김동길 慶北大學校 齒科大學 1995 慶北齒大論文集 Vol.12 No.2

치아의 발육 및 맹출에 따른 신경지배의 발달을 관찰하기 위하여 출생후 1,5,10,15,20,25,35일 된 백서 및 성장이 완료된 백서 각 5마리씩 총 40마리의 하악 구치를 대상으로 neurofilament protein(NFP)과 calcitonin gene-related peptide(CGRP)의 항체를 이용한 면역조직화학적방법을 사용하였으며 결론은 아래와 같다. . NFP 면역반응 신경섬유보다 CGRP면역반응 신경섬유의 분포밀도가 높게 나타났다. 그러나 NFP 면역반응 신경섬유는 비교적 선이 명확한 외형을 나타내는 반면 CGRP 면역반응 신경섬유는 외형이 거칠면서 염주알 모양을 나타냈다. . 치수내 신경섬유의 진입은 상아질 형서이 시작되는 시기였다. Raschkow plexus는 치근형성시기 부터 발달하여 치아가 구강내로 맹출되면서 보다 발달되었다. 조상아세포층으로 진입하는 신경섬유도 치아가 구강내로 맹출하면서 밀도가 높아졌다. . 치조점막상피의 신경지배는 치아의 발육 및 맹출과 관련하여 발달하였다. 치주인대의 신경지배도 치근 형성과 함께 발달하였다. . 신경지배 발달은 역연령(chronological age)보다 치아연령(dental age)에 따르는 것으로 나타났다. The purpsoe of this study was to investigate the postnatal development of dental innervation with the tooth development and eruption process in developing rat mandibular molars(postnatal 1, 5, 10, 15, 20, 25, 35day-old and adult rats). Immunohistochemical method was carried out for the detection of nerve fibers, using the antibodies against neurofilament protein(NEP) and calcitonin gene-related peptide(CGRP). The results were as follows: 1. The distribution of CGRP immunoreactive(IR) nerve fibers was more densely detected than the NFP-IR nerve fibers. The feature of CGRP-IR nerve fibers were shown in a bead-like appearance and that was more frequently revealed in nerve terminal and immature stages of development. 2. The time of nerve entering into the dental papilla of tooth follicle began at the occured advanced dentinogenesis. The development of Raschkow plexus began at the formative stage of the roots and was accelerated at the stage of the crown emerged into the oral cavity. The number of nerve fibers entering the odontoblastic layer increased with the tooth eruption and mastication. 3. The development of the innervation in the alveolar mucosa was represented associated with dental development and erupiton. The innervation of preiodontal ligament developed according to the eruption of tooth. 4. The development of innervation was shown to be related with the stage of the development of individual teeth rather than the chronological age of the rat.
