멸균 방법에 따른 교정용 플라이어의 물성 변화에 대한 비교 연구

조일제,손우성 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.2

간염이나 AIDS의 영향으로 멸균에 대한 관심이 높아지고 있으며, 교정 진료실에서도 교정용 플라이어의 멸균이 필요하게 되었다. 제조회사에서는 멸균과정의 열이 교정용 플라이어에서의 야금학적 변화를 야기하지 않는다고 하지만 교정치과의사들은 가압 증기 멸균기나 대류식 건열 멸균기를 이용하여 반복적으로 멸균을 시행한 경우에 ligatrue cutter의 날이 쉽게 무디어져서 ligature cutter의 수명이 짧아진다는 것을 임상적 경험으로 알고 있다. 본 연구는 멸균과정이 교정용 플라이어의 물성에 미치는 영향을 알아보기 위하여 시행되었다. 본 연구에 사용된 교정용 플라이어는 멸균과정을 견딜 수 있도록 개발했다고 주장하는 AEZ, Unitek과 Dentronix ligature cutter이었고, 멸균기는 대류식 건열 멸균기인 Bowmar RHT-1000과 Dentronix DDS-5000와 가압 증기 멸균기인 Eschmann SES-2000이었다. 멸균하기 전과 200회와 400회 멸균한 후의 ligature cutter의 날 부위의 표면과 파단면의 상태는 주사 전자 현미경으로, 미세 조직은 광학 현미경으로 관찰하고, micro-Vickers와 Rockwell 경도 시험기로 경도를 측정하고, SEM-EDX로 조성분석을 시행하여 다음과 같은 결론을 얻었다. 1. 주사 전자 현미경을 이용한 교정용 플라이어의 날 부위의 표면과 파단면의 관찰에 의하면 멸균 횟수의 증가에 따라서 표면 조직에서 검은 반점 형태의 부식 생성물의 수와 크기가 증가하는 경향이 있었으며, 파단면의 관찰에서도 멸균 횟수의 증가에 따라서 전형적인 취성 파면인 벽개면의 분포율이 증가하는 경향이 있었다. 이러한 부식 현상과 금속 조직의 취성화로 기계적인 특성이 저하될 것으로 사료되었다. 2. 광학 현미경을 이용한 미세 조직 사진의 관찰에서도 멸균횟수의 증가에 따라서 Cr계 탄화물의 수와 크기가 증가하는 경향이 있었다. 이러한 금속 조직의 조대화에 따라서 기계적 특성이 저하된 것으로 생각되었다. 3. 교정용 플라이어의 날 부위의 경도는 멸균 횟수의 증가에 따라서 감소되었는데 경도의 감소는 멸균에 의한 부식생성물과 표면조직의 변화에 따른 것으로 생각되었다. 4. SEM-EDX를 이용한 조성분석의 결과에 의하면 AEZ과 Unitek ligature cutter는 Fe-Cr계 stainless steel이었고, Dentronix ligature cutter는 Co-Cr계 합금이었는데, 제조회사에 따라서 금속의 조성은 달랐지만, 멸균 전후의 비교에서는 큰 차이가 없었다. 5. 반복적으로 멸균을 하면서 실제 임상에서 사용한 교정용 플라이어의 날의 표면 조직을 주사 전자현미경으로 관찰한 결과, 미세 균열을 발견할 수 있었다. Sterilization has received much attention in orthodontic practices over the past several years. The present study was undertaken to investigate the effects of sterilization on the physical properties of orthodontic pliers-AEZ, after 200 and 400 sterilization cycles using the Bowmar RHT-1000, the Dentronix DDS-5000, and the Eschmann SES-2000. The tip surface and the fracture and the fracture surface were observed with a scanning electron microscope. The microstructure was observed with an optical microscope. The hardness test was carried out with the micro-Vickers hardness tester and the Rockwell C Scale hardness tester. The chemical composition was analyzed by energy dispersive X-ray spectrometer. The results of this study were as follows: 1. The number and the size of corrosion products on the tip surface and the proportion of cleavage planes in fractured specimen increased, but the hardness of the tip decreased in proportion to sterilization cycles. From these observations, it was considered that mechanical properities decreased in proportion to sterilization cycles. 2. The number and the size of chromium carbides increased in proportion to sterilization cycles. Coarse microstructrue decreased mechanical properities. 3. The AEZ and Unitek ligature cutters were Fe-Cr stainless steel, but the Dentronix ligature cutter was Co-Cr alloy. There were differences among manufactures, but the chemical composition was not changed after sterilization cycles. 4. The tip edge of ligature cutter used in a clinic revealed microcracks with the SEM observation. Clinical experience confirmed that ligature cutters were gradually degraded by sterilization.

D. H. 로렌스 소설의 숲과 자아변화

조일제 ( Il Jae Jo ) 한국로렌스학회 2013 D.H. 로렌스 연구 Vol.21 No.1

This paper is intended to examine the change of characteristics of major characters` selves in D.H. Lawrence`s novels while they are in the forest or trees. The forest or the tree is a source of creativity, wisdom, imagination, and inspiration in Lawrence`s novels. A man and a woman in the novel will be ease, peaceful, comfortable, vital, and rich in his or her feeling and emotion when he or she is present in trees and the forest. However trees and forest can paly a negative, undesirable, destructive force and effect to people as well. So they have double, and ambivalent values. Lawrence keeps abundant, keen senses, full recognition, and enough knowledges about effects and influences of trees and forest. The writer`s description of trees and forest in his novels must be given notice and attention for understanding of Lawrence`s novels. The paper will deal with Lawrence`s (short) novels such as “The Shadow in the Rose Garden,” “The Shades of Spring,” “Sun,” Sons and Lovers, The Rainbow, Women in Love, Lady Chatterley`s Lover, Kangaroo, The Boy in the Bush. For the first seven novels, the creative, positive effects of the forest are touched, but for the last two novels, negative, destructive effects are touched in terms of the so-called Australian bush dark and strange, and mysterious. In addition, this paper will touch on Lawrence`s emphasis of place and space. Lawrence`s talk and discussion of ``the spirit of place`` are critical because it exercises an important role and influence in his literature. ``The spirit of place`` is the title of the foreword of D.H. Lawrence`s Studies in Classic American Literature. It is a very important topic in Lawrence`s literary discussion. His talk about the old Indian wisdom of the forest, and about German Hercynian Wood in connection with old Roman military forces` invasion into Germany appears in Fantasia of the Unconscious. Place`s soul or spirit in the forest and trees which Lawrence calls ``the spirit of place`` is examined in the paper for the more exact, right understanding of his novels.

D.H. Lawrence의 인디언 종교 : The Plumed Serpent, The Woman Who Rode Away를 중심으로

趙一濟,黃圭軾 釜山大學校 1984 人文論叢 Vol.26 No.1

D. H. Lawrence had looked over all the world for something that would strike him as religious. American Indian religion which he had experienced was a revelation to him. He says in the travel essay, 'New Mexico': "It is curious that one should get a sense of living religion from the Red Indians, having failed to get it from Hindus or Sicilian Catholics or Cingalese." The gods of Indians are "dark gods", cosmic gods which come from the relation between man and his circumambient universe or nature. They believe in the Sun, Serpent, and Eagle, which has greater vitality than any other, as their gods. Lawrence thinks that Christianity is ill and false. He, in The Plumed Serpent, burns the statues, idols, signs, and other religious things of Jesus, Maria, and Saints, instead, revives the old Mexicon gods, Quetzalcoatl, Huitzilopochtli and Malintzi. And among the male heroes, Don Ramon becomes the Quetzalcoatl God, Don Cipriano becomes Huitzilopochtli God, and female hero, Kate becomes Malintzi Godness. They are oll manifestation of the gods. Indian gods are half-devil, and half-devine. Sometimes the gods become demon-god. Don Ramon and Don Cipriano sometimes give horrible feelings to Kate as demonic gods. At the same time, both of the male heroes shows themselves to Kate with mysterious phallic power. Kate is half greatly moved, and feels half repellent by them. There are terrible blood-sacrificial ritual in The Plumed Serpent and The Woman Who Rode Away. But Lawrence shows, through the ritual, that it is mysterious;that is, death is rebirth or revival of life. Lawrence has belief that the eternity of cosmic life is revealed by such ritual. And in the ritual, Lawrence reveals that man or trite can obtain tile power, strength, energy, and mastery of his own by knowing or communicating with the sun, eagle, or serpent, namely cosmos or nature.

양자역학의 개념과 핀천의『중력의 무지개』읽기

조일제,김상구 현대영미어문학회 2014 현대영미어문학 Vol.32 No.1

This article is intended to examine the interactive relationship, and interdisciplinarity between literature and science. It gives a hermeneutic explanation and analytical interpretation of how Thomas Pynchon's novel Gravity's Rainbow is connected with quantum mechanics and how it is represented, based on "hidden variable theory" in modern science. Thus major character Slothrop and other characters related to him are analyzed for their mysterious, difficult actions in connection with principles and characteristics of quantum mechanics. The hidden variable theory contains field concept, relativity theory, quantum mechanics, and etc. Gravity's Rainbow shows various scientific theories and discourses, and postmodern society's traits and falls to the fiction in the quantum universe. Many characters, images and motifs in this novel are interconnected and they are not separated from the whole, but placed as a individual whole in the world. The parallel between literature and science is provided on the basis of quantum mechanics.

D. H. 로렌스 문학의 동물-되기 모티프와 공감적-초월적 커뮤니케이션

조일제(Jo, Il-Jae) 새한영어영문학회 2019 새한영어영문학 Vol.61 No.1

This article examines and identifies the becominganimal motif and sympathetic, transcendental interaction and communication in works of D. H. Lawrence centering on with some novels. There are a lot of scenes in Lawrence’s such novels where a primitive magical self and mysterious, transcendental consciousness appear in the interaction and communication between characters and animals as spontaneous nature which leads into bloodbeing or flesh-consciousness. Such kinds of being self, and consciousness, according to Lawrence, belong to a great half of darkness. Modern European civilization has lost and forgotten those aspects in the human beings, which results from over-oriented mental, intellectual consciousness that causes the destruction of the fundamental self from human beings. So modern people must restore the animality or otherness of the great half which is a primitive, and fundamental nature.
