This study intended to explore the basic materials related to In-chon Teachers College climate for the purpose of a formal discussion to creat developmental College climate. This study would only supply the materials concerned with the college climate to a formal discussion. Therefore, there was no conclusion in this study. What kind of college climate do we have to creat, who should do it, and how do we establish a strategy to disseminate a college climate are different questions. These are problems we should solve through a formal discussion in In-chon Teachers College. We tried to fine out four facts in this study. The four facts which we tried to find out were as follows: 1. What is the college climate? 2. Is it necessary for In-chon Teachers College to have a college climate? 3. What kind of college climate are there in In-chon Teachers College now? 4. Is the challege climate which In-chon Teachers College has now positive or negative? To find out these facts we analysised In-chon Teachers college`s situation, other teachers College`s situations, and some materials concerned with the college climate. And we surveyed In-chon Teachers College students` and professors` opinions. Through these works what we found were as follows: 1. The college climate is a disposition of college members, which is derived from the college character. It means that a college character affects the college members` behaviors. 2. In-chon Teachers College needs a college climate in order to effectively accomplish the purpose of teachers college. 3. In-chon Teachers College does not have an evident college climate. 4. We cannot evaluate the In-chon Teachers College climate. Because it does not have and evident college climate. Even though In-chon Teachers College needs an evident college climate, the college members do not pay attention to it till now. From now on, the college members should try to creat a college climate. To creat a college climate in In-chon Teachers College, what we have to discuss further are as follows: 1. Who should be the main group to creat a college climate? 2. What kind of college climate should we creat and what is the reason? 3. How do we establish a strategy to disseminate a college climate?

전인기,김훈희,김성진,이승철,원영호 대한의진균학회 1997 대한의진균학회지 Vol.2 No.2

Background : Sporotrichosis is most common deep cutaneous fungal disease in Korea. It is markedly variable in incidence, distribution, and colinical pattern. The epidemiology have been well known to change over years, and to be influenced by environmental condition and geographic location. Sporotrichosis in Kwangju and Chonnam area is more prevalent compared to other areas in Korea. Objective : Our purpose was to describe the prevalence, epidemiological and clinical features, regional distribution and the change of the incidence according to the climate in different regions. Method : the observation of 103 sporotrichosis patients confirmed by clinical, histopathological and mycological studies had been made in the Department of Dermatology at Chonnam National university Hospital for thirty years from 1967 to 1996. Results and Conclusion : The sporotrichosis patient was 0.09% of 108, 680 outpatients, prevalent at the age of thirties and forties(20%), and 3.2:1 in the ration between male and female. The 58% of total cases visited us within 3 months after the beginning of skin lesion. Almost all initial lesions appeared on the exposed areas, especially upper extremities(68%). The 74% of the total cases was lymphocutaneous type, and the rest was fixed cutaneous type. Most popular occupation of patients was farmer(60%). The 69% of patients visited in spring and winter, especially in february(17%). The incidence of sporotrichosis per average 100,000 population in districts of Kwangju and Chonnam area revealed a difference with the amount of rainfall in winter; average 1.8 person in an area above 125㎜,0.8 person in an area between 100㎜ and 125㎜, and 0.2 person in an area below 100㎜ These rsults suggest that the incidence and clinical features of sporotrichosis are influenced by occupations, leisure and occupational activities, living conditions, and the climate.

내분비교란 물질에 노출된 C.plumosus(장수깔따구)의 하순기절 기형성

곽인실,이원철 한국육수학회 2005 생태와 환경 Vol.38 No.1

야외에서 채집한 C. plumosus를 대상으로 잠재적 내분비계 교란물질인 DEHP, BPA 및 Tebufenozide를 처리 물질로 하여 형태적인 교란 효과를 살펴보았다. 약제에 노출된 개체의 하순기절은 부드러워지거나(smooth) 손실(loss)이 가장 많았으며 엷은 갈색을 보였다. 처리 물질에 따른 기형의 정도를 살펴보면, DEHP는 46.2~85.7%, BPA는 73.7 ~90.9% 그리고 tebufenozide는 57.6~78.9%가 기형을 입어 BPA>tebufenozide>DEHP순으로 기형이 크게 나타났다. 처리 물질별 기형 부위를 살펴보면, MIX(32~46%)>MLT(25~34%)>LT(3~7%)로 두 부분이 함께 기형을 입는 형태가 가장 많았으며 LT단독의 기형이 가장 적었다 MIX형태로 기형이 가장 높은 물질은 BPA (46%) > DEHP(33%) > tebufenozide (32%)이고, MLT에 가장 높은 기형을 보인 것은 DEHP(34%) > tebufenozide (31%)>BPA(25%)로 나타났다. Tebufenozide처리에 따른 하순기절의 색은 처리 농도가 높아지면 엷은 갈색 하순기절의 발생 빈도가 증가되었다(27.8~84.2%). 반면, BPA(8.7%)와 DEHP (18.2%)는 1 ㎍L^(-1)에서 가장 낮은 엷은 갈색의 하순기절의 발생 빈도를 보였으나 0.3㎍L^(-1)처리에서는 매우 높은 엷은 갈색의 하순기절이 다수 발생하였다(BPA 52.6%; DEHP 30.8%). Egg masses of C. plumosus were collected from Jungnang Stream in Seoul and reared in an incubator chamber. The larvae of C. plumosus were treated with potential endocrine disruption chemicals (EDCs) such as Diethylhexyl phthalate (DEHP), Bisphenol A (BPA) and Tebufenozide, and the effects of morphological abnormalities were observed. The deformities of the mentum following exposure to EDCs showed the smooth/round tooth, the loss of 1 tooth, reduced median lateral teeth (MLT) and light brown color. The incidence rates of the mentum deformity were associated with chemicals: BPA (73.7~90.9%)>tebufenozide (57.6~78.9%) > DEHP (46.2~85.7%). The deformity type of the mentum showed MIX (MLT+LT, 32 46%) > MLT (25~34%) > LT (lateral teeth, 3~7%). Also, the incidence of MIX type was in the order of BPA (46%) > DEHP (33%) > tebufenozide (32%), and that of MLT type showed DEHP (34%) > tebufenozide (31%) > BPA (25%). As the concentration of Tebufenozide increased, the incidence of light brown mentum was dose dependent. While the incidences of light brown mentum following exposure to BPA and DEHP were not associated with their concentrations.

강인규,권대룡,성용길 동국대학교 자연과학연구소 1991 자연과학연구 논문집 Vol.11 No.-

Poly(γ-benzyl L-glutamate) (PBLG)의 측쇄에 polyethylene glycol(PEG) 또는 ethanolamie(EA)을 반응시켜 적심성이 서로 다른 몇가지 폴리펩티드 공중합체를 합성하였고, 이들 공중함체의 약물방출특성을 살펴보았다. 합성된 폴리펩티드공중합체의 수분흡수율은 공중합체 중의 PEG 또는 EA 함량이 높아짐에 따라 증가하였다. PEG-PBLG-EA 공중합체로부터의 5-fluorouracil의 방출속도는 PEG-PBLG 공중합체로부터의 방출속도보다 크게 나타났으며, 이러한 결과는 팽윤성의 폴리펩티드를 합성하고자 할 때 사용되는 치환제로서는 PEG보다도 EA가 더욱 효과적이라는 것이 나타났다. 한편, PEG를 가교시킨 PBLG 공중합체막상에서는 5-fluorouracil의 방출에 기인하여 작은 pores를 명료하게 나타나고 있음을 알 수 있었다. Several copolypeptides having different swellabilities are are synthesized by introducing polyethylene glycol(PEG) or ethanolamine(EA) to the side chains of poly(γ-benzyl L-glutamate) (PBLG) and their drug release characteristics are examined. The degree of swelling of copolypeptide is increased by increasing PEG or EA content in the polymer. The release rate of 5-fluorouracil from the PEG-PBLG-EA copolymers was higher than that of the PEG-PBLG copolymers. This results indicated that EA is more effective than PEG for the preparation of the swellable polypeptides. It was observed, from the morphological study by scanning electron microscope, the pores are generated on the PEG-crosslinked PBLG, but not on the PEG-grafted-PBLG.

徐仁銖 漢陽大學校 1979 論文集 Vol.13 No.-

The author has observed the specificity and antigenecity of two kinds of antigen, one of which is carbohydrate moiety and the other is the protein. Measurement of hemolysin titre: The immunized serum of rabbits by sheep RBC was used as haemolysin, and it was used in three fold concentration of the complete hemolysis titrated preliminary test. Hemolysin was always used after deciding its titre at preliminary tet. The sheep RBC suspension was used by 3 per cent. The dosage of antigen:1/2 amount of the maximum haemolysin does, determined by the result of preliminary test of the author's two kinds of antigen, was used. Complement: Complement was obtained by the heart puncture of healthy guinea pigs. The two fold amount of the complement titre at preliminary titration was used in this experiment. Test sera were all supplied from the from the patients who were recieving treat-ment in the T. B. centre attached to the Ministry of Health and Welfare of Korea. These sera were inactivated by heating at 56℃ for 30 min., and when they were needed preservation, they were stored in refrigerator at 40℃± and were reheated at 56℃ for 15min. just before submitting to the experiment. Procedures of making antigens: C antigen-Very virulent human tubercle bacillus strain C is cultivated for 40 days on Sauton's non-protein media, and washed several times with saline on the filter papers. After dessication, the organisms are suspended in saline at the rate of 10 mg/ml and submitted to the rapid manipulation of freezing and thawing between -20℃ and 20℃;after 20 times of this manipulation, it is centrifuged at 8,000 rpm for 30 min, and its supernatant is picked up as C antigen. P-antigen: The same dried strain as used in making the C antigen is heated by steam at 100℃ for 30min., filtered through Seitz filter, into this filtered fluid added 40% trichlor acetic acid at the rate of 4 per cent, and set this fluid at 4℃±all day long and overnight. After then, its sedimented substance is isolated, suspended in 1% trichlor acetic acid solution, centrifuged by 3,000 rpm for 10 min., and its sedimented substance is re-picked up. This procedures are repeated twice more quite the same way, and into the finally got substance .by centrifugation is added 0.3% KH₂PO₄in approximate amount, and, after enough mixing, it is centrifuged so as to wash away the trichlor acetic acid. This manipulation of washing must be repeated three timesm and then the sediment is dried without heating, its powder is dissolved in phosphate buffered solution (pH 7.0) at the rate of 1.0 mg/ml, then it is the stock solution of P antigen, (the dried powder was got at the rate of 10.1mg from 2,500 ml of filtered fluid, and the total nitrogen amount was 13.34% by microki jeldahl method). The complement-fixation-reaction was carried out in T. B. serum using P-and C-antigens made by the author, and following results were obtained: 1) Both P-and C-antigens had neither anti-complement, nor exclusive hemolytic action. 2) Antigenecity of C-antigen is weak, and becomes weaker by heating and by preserving long time, while that of P-antigen being considerable high and never influenced by heating or by long period of preservation that is, not decreased even by heating at 60℃ for 30minutes, nor by preservation for 3 days at 37℃, nor for one month at room temperature. 3) Proving of antibody for the complement-fixation-reaction in lung T.B. serums is difficult immediately after drawing of blood, but it gradually increases as time goes, about 7 days later it becoming the maximum, and ,then after 12 days, again, it disappears. 4) Antibody detecting rate of lung T.B. is paralell with the degree of disease severity, but in utmost severe cases it's detection is rather difficult. 5) The rate of non-specific positive reaction by P-antigen with syphilis serum is low. 6) But with leprosy serum the non-specific positive rate of P-antigen is considerably high, especially in nodular case it is twice that of nervous leprosy. 7) The non-specific positive rate of P-antigen to the serum of healthy person is very low.

황인남,오원만,류선열 전남대학교 치과대학 1992 전남치대논문집 Vol.4 No.1

Color stability of tooth colored restorative resins is an important factor, particularly in anterior teeth restoration. The purpose of this study was to evaluate the color stability and opacity change of several light curing composite resins. Specimens of eight composite resins(Prisma AP.H, Brilliant Enamel, Charisma, Durafil, Helio Progress, Herculite XR, P-50 and Silux Plus) were divided into two groups : In Group 1, the specimens were polymerized by visible light curing unit for 60 seconds on both sides and in Group 2, the post-cured specimens were heat tempered by light/heat curing unit for 45 units(about 18 min.). All specimens were stored in distilled water at 60℃ for 30 days. The color characteristics(L^*, a^*, b^*) and opacity of the specimens before and after immersion were measured by spectrocolorimetry and the total color difference(ΔE^*) and opacity change(ΔY%) were computed. The results obtained were as follows: 1. SP and APH in both groups, DF, HP and HXR in Group Ⅰ showed ΔE^*-value above 2.0. 2. DF, HP, SP and HXR in Group Ⅰ showed higher ΔE^*-value than in Group 2, but the others had no significant difference. 3. The opacity of CH and HXR in Group Ⅰ, and of CH and BE in Group 2 decreased after immersion, while that of the others increased. 4. Opacity change of BE, P50 and HXR was significantly different between Group Ⅰ and 2. These results suggest that color change in the post-cure heat tempered specimens by light/heat curing unit was smaller than that of the specimens polymerized by visible light curing unit. No clinically detectable opacity changes were noted for any materials in either group.

Samarium Lutidinate 착물형성에 관한 열역학적 연구

김인회 建陽大學校 1994 建陽論叢 Vol.- No.3

The thermodynamic parameters of formation of the 1:1 complex between samarium cation and lutidinate have been measured using potentiometric and calorimetric techniques in aqueous solution of 0.50M (NaClO₄) ionic strength at 25℃. The results have been compared with those for the other analogous heterocyclic carboxylate ligands. From the comparison of the thermodynamic data, it was found that the lutidinate ligand was coordinated to the samarium cation by forming the chelate through the ring nitrogen atom at position 1 and the carboxylate group at position 2 of the pyridine ring.

초·중등교육에서의 학습객체 개념 활용 가능성 고찰

박인우,임진호 한국컴퓨터교육학회 2003 컴퓨터교육학회 논문지 Vol.6 No.2

현재 많은 기업 및 사이버대학에서는 표준화된 컨텐츠의 개발에 많은 시간과 자본을 투자하고 있다. 특히 SCORM(Sharable Content Object Reference Model)표준을 적용한 콘텐츠개발은 물론, 표준에 맞는 LCMS(Learning Content Management System)의 도입을 적극 추진하고 있다. 그러나, 성인학습 대상의 e-Learning 분야에서의 기대와 관심과는 다르게 초·중등교육 부문에서의 SCORM의 활용에 대한 견해는 대체로 부정적이며, 그 실효성에 의문이 제기되고 있기도 하다. 이에 SCORM의 핵심적인 개념인 학습객체 개념에 대해 조사하고 이러한 학습객체 개념이 초·중등 교육에 활용될 수 있는지에 대한 한계점과 가능성을 살펴봄으로써 SCORM에서의 학습객체가 갖는 교육학적 시사점을 모색해 보았다. Currently many companies and cyber-universities are investing large amount of time and efforts to develop a standard for Web-based learning contents. Among various standards proposed, SCORM(Sharable Content Object Reference Model) has been especially interested regarding web contents and LCMS(Learning Content Management System), In contrast with corporate and adult education, many seem to be skeptical that SCORM could be applied to K-12 education. In the study, opportunities and limitations of the concept for the learning object in 'SCORM' are examined through analyzing relevant studies and cases. In addition, this study examines the learning object in the pedagogical Perspective, and derives suggestions for applying them to K-12 education.

Contourlet 변환을 사용한 효과적인 방향성의 다해상도 영상 표현에 관한 연구

池仁鎬,張仙奉 弘益大學校 産業技術硏究所 2007 産業技術 Vol.17 No.-

In this paper, we purse a true two-dimensional transform that can capture the intrinsic geometrical structure that is key in visual information. The main challenge in exploring geometry In Images comes from the discrete nature of the data. We construct a discrete-domain multiresolution and multidirection expansion using nonseparable filter banks, in much the same way that waveleta were derived from filter banks. This construction results in a flexible multiresolution, local, and directional image expansion using contour segments, and thus, it is named the contour let transform. We establish a precise Iink between the developed fiIter bank and the associated cont i nuous-doamin contourlet expansion via a directional multiresolution analysis framework.
