김정희,Kim, Chung-Hee 한국분석과학회 1992 분석과학 Vol.5 No.4

산화칼슘과 산화철을 0.6:1.4, 0.8:1.2, 1.0:1.0 몰비로 혼합하여 만든 디스크 형태의 시편들을 $1400^{\circ}C$ 산소 분위기와 수소 분위기하에서 각각 소결하였다. 수소 분위기하에서 만든 calcium ferrite 막전극이 산소 분위기하에서 만든 calcium ferrite 막전극 보다 더 우수한 감응전위와 감응농도범위를 나타냈다. 수소 분위기하에서 만든 calcium ferrite ($CaO:Fe_2O_3=0.6:1.4$ 몰비) 막전극은 $Ca^{2+}$, $Ba^{2+}$, $Mg^{2+}$, $Zn^{2+}$와 같은 2가 금속 양이온과 $I^-$, $Br^-$와 같은 할로겐 음이온에 대하여 Nernstian 기울기에 근접한 높은 감응전위를 나타내었다. The ion-selectrodes based on calcium ferrite were prepared by mixing calcium oxide with ferric oxide on molar ratio of 0.6:1.4, 0.8:1.2, 1.0:1.0, respectively. The specimens were sintered at $1400^{\circ}C$ for 2hrs in $O_2$ and for 20min in $H_2$ atmosphere. The selectrode sintered in hydrogen atmosphere showed better responded potential and wider range of responded concentration than selectrode sintered in oxygen atmosphere. The ion-selectrodes base on calcium ferrite(0.6:1.4 molar ratio.) showed the highest potential to bivalent cations such as $Ca^{2+}$, $Ba^{2+}$, $Mg^{2+}$, $Zn^{2+}$ and halogen anions such as $I^-$, $Br^-$ in the range of $10^{-1}{\sim}10^{-7}M$. It showed good agreement with theoretical nernstian values.

김정희,정재헌,조규종,Kim, Joung-Hee,Chung, Chae-Heon,Cho, Kyu-Zong 대한치과보철학회 1990 대한치과보철학회지 Vol.28 No.1

The purpose of this study was to analyze the displacement and the magnitude and the mode of distribution of the stresses in the lower overdenture, the mucous membrane, the abutment tooth and the mandibular supporting bone when various denture base materials, such as acrylic resin and 0.5mm metal base, and various denture base designs were subjected to different loading schemes. For this study, the two-dimensional finite element method was used. Mandibular arch models, with only canine remaining, were fabricated. In the first denture base design, a space, approximately 1mm thick, was prepared between the denture and the dome abutment. In the second denture base design, contact between the denture and the dome abutment was eliminated except the contact of the occlusal third of the abutment. In order to represent the same physiological condition as the fixed areas of the mandible under loading schemes, the eight nodes which lie at the mandibular angle region, the coronoid process and the mandibular condyle were assumed to be fixed. Each model was loaded with a magnitude of 10 kgs on the first molar region(P1) and 7 kgs on the central incisal region (P2) in a vertical direction. Then the force of 10 kgs was applied distributively from the first premolar to the second molar of each model in a vertical direction(P3). The results were as follows. : 1. When the testing vertical loads were given to the selected points of the overdenture, the overdenture showed the rotatory phenomenon, as well as sinking and the displacements of alveolar ridge, abutment and lower border of mandible under the metal base overdenture were less than those under the acrylic resin overdenture. 2. The maximum principal stresses(the maximum tensile stresses) being considered, high tensile stresses occured at the buccal shelf area, the posterior region of the ridge crest and the anterior border region of the mandibular ramus. 3. The minimum principal stresses(the maximum compressive stresses) being considered, high compressive stresses occured at the inferior and posterior border region of the mandible, the mandibular angle and the posterior border region of the mandibular ramus. 4. The vertical load on the central incisal region(P2) produced higher equivalent stress in the mandible than that on any other region(P1, P3) because of the long lever arm distance from the fixed points to the loading point. 5. Higher equivalent stresses were distributed throughout the metal base overdenture than the resin base overdenture under the same loading condition. 6. The case of occlusal third contact of the abutment to the denture produced higher equivalent stresses in the abutment, the mandibular area around the abutment and the overdenture than the case of a 1mm space between the denture and the abutment. 7. Without regard to overdenture base materials and designs, the amounts and distribution patterns of equivalent stresses under the same loading condition were similar in the mucous membrane.

This study was conducted to develop a novel tomato sauce using natural seasoning. The data was analyzed using SPSS for Windows (version 14.0). Two factors of the tomato sauce were varied was tomato paste and sugar. Nine tomato sauces were produced with various compounding ratios of tomato paste and sugar. The color, viscosity and sensory evaluations of the nine tomato sauces were determined. Items examined in the sensory evaluation were color, sweetness, viscosity and overall quality. Sweetness($4.44{\pm}1.36$), viscosity($5.16{\pm}1.28$) and overall quality($4.68{\pm}1.11$) of the tomato paste 340g and sugar 100 g sample got highest scores. Therefore, this composition was used as tomato spaghetti sauce. Tomato spaghetti sauce using a natural tomato sauce and artificial tomato sauce was prepared and subjected to a sensory evaluation. Items included in the sensory evaluation were taste, flavor, harmony, overall quality. In this analysis, all sensory item scores of the tomato spaghetti sauce using natural seasoning were significantly higher than when artificial seasoning was used. Therefore, the potential of commercialization of tomato sauces using natural seasoning was confirmed.

자의식과 "막강한 전체성"의 기억: 스턴이 추구하는 자아의 자유의 역설적 연대성

김정희 ( Chung Hee Kim ) 근대영미소설학회 1998 근대 영미소설 Vol.5 No.2

This paper tries to reexamine the function of self-consciousness in Laurence Sterne`s Tristram Shandy Tristram as a self-conscious narrator is a thesis widely popularized by Wayne Booth and many critics often examine Tristram`s self-consciousness as a matrix of the unity of the text. For Sterne, however, unity of either self or a text is a problematic concept which not only disrupts but undermines human- "apacity to experience oneness with others I suggest that Sterne`s moral intention III Tristram Shandy is to expose and counteract the human tendencies which intensify our vexations about the uncertainty and elusiveness of the meaning of life, irritations that compel us to be preoccupied with the possibility of securing certainties about self. Sterne engages as a major target self-consciousness of the type defined by Hegel. Sterne`s particular ways of problematizing the Cartesian search for certainty of self prefigures certain arguments found in Hegel`s rendition of the master/slave dialetic. Hegel argues that a self-consciousness, which arises from the desire for unequal, one-sided recognition, ascertains self as an essential being, by refusing the vulnerable thingness in self, while denying to the other the status as an essential being. However, the victor or master achieves recognition from an unequal loser, or an inferior recognition, while losing self-sufficiency by becoming dependent on the mateial production of the slave. Sterne recommends our escape from this dialectic by highlighting the pleasures of mutual recognition. To create an ambience in which mutual recognition can be facilitated, Sterne grants his narrator the freedom to celebrate his insecure and fallible self in the context of a Rabelaisian affirmation of the "mighty whole" which defiantly yet delightfully accommodates the infinitely vaned modes of unfinished, fragmentary beings Drawing on Bakhtin`s explication of Romantic Grotesque genre in which he names Sterne as a founder of this genre, I argue that the peculiar convergence in Tristram Shandy between the grotesque (which shatters individuating barriers) and the Romantic (which strengthens the claims of individual self-hood) allows the former to substantlate and control simultaneously the claims of the latter. In other words, Sterne reveals that an individual`s freedom of self is concrete only when s/he recognizes the solidarity among the heterogeneous,unfinished, fragmentary being.

이 연구는 가상환경에서 점포이미지에 영향을 주는 선행요인을 모색하고, 그러한 요인들의 결합이 사이버 소비자의 이미지추론에 어떠한 영향을 미치는지를 살펴 보았다. 또한, 가상점포이미지에 의한 사이버 소비자의 추론은 고객만족도와 가상 점포충성도에 어떠한 영향을 미치는지를 규명했다. 연구결과는 다음과 같이 요약된다. 첫째, 가상점포의 제품구색, 촉진, 인터페이스 등과 같은 요인들이 점포이미지형성에 기여하며, 이들 요인들은 가상점포이미지 구성요인이라기보다는 점포 이미지의 선행요인임이 입증되었다. 둘째, 가상점포이미지가 호의적일수록 고객 만족도는 높아진다. 셋째, 가상점포이미지가 호의적일수록 가상점포충성도는 향상된다. 넷째 고객만족도가 높을수록 가상점포충성도는 향상된다. Recently, the role of Internet becomes wide so that it could provide the information among users as well as the opportunity to make commercial transactions in the cyberspace. Now, the virtual storefronts are the virtual space where anyone makes a profit on Internet by selling and buying goods/services. Therefore, it is important to develop the good image for cyberconsumers so that virtual storefronts can attract many browser to buy goods. The study reported examines how combination of specific elements in the internet environment influence cyberconsumers' inferences about the virtual storefront and discusses the extent to which these inferences mediate the virtual storefront loyalty. Results show that the virtual storefront elements were posited to be antecedents of virtual storefront image rather than components of virtual storefront image. In addition, the virtual storefront image mediators the satisfaction and loyalty of cyberconsumer on virtual storefront.
