DC magnetron sputtering방법에 의해 Corning glass기판 위에 ?? 형태로 다층박막을 제작하여 버퍼층 종류(Fe, Cu, Cr, Ta)와 두께, 비자성층인 Cu두께 변화에 관한 자기저항비의존성을 조사하였다. 또한 이들 시료에 대하여 열처리를 행한 후 열처리가 이 시료의 구조, 자기적 성질 및 자기저항에 미치는 영향을 조사하였다. Fe버퍼층의 두께가 60Å일 때 극대 자기저항비가 14%인 자기저항이 관찰되었고 Fe버퍼층과 Cr버퍼층을 갖는 시료를 비교한 경우 자기저항비는 그다지 차이가 없으나 Fe버퍼층이 있는 경우에 더 큰 포화자기장 및 자기 이력현상을 나타내었다. 250℃까지의 시료에 대한 열처리는 다층박막의 주기성을 유지한채 더 큰 결정립을 갖게 하여 자기저항비는 증가하였으나 그 이상의 온도에서는 계면 혼합 및 계면 확산에 의한 감소를 나타내었다. Giant magnetoresistance (GMR) and magnetic properties of CoFe/Cu multilayers prepared by dcmagnetron sputtering has been studied. We investigated the effect of Fe buffer layer thickness, different buffer layers, and annealing condition on GMR. For the 60Å Fe buffer layer thickness, maximum MR ratio 14% was found. When we have used different buffer layers, multilayers with Cr and Fe buffer show similar GMR magnitude, but multilayers with an Fe buffer have much higher saturation fields and hysteresis. The study of the dependence of the MR behaviors on annealing temperature, the MR ratio was increased to 250℃, but reduced at the temperature higher than 300℃ because of the interfacial diffuse.

목적 : Salmonella typhi Ty21a 주로 만든 경구용 약독화 장티푸스 생균 백신 투여 후 위장관의 점막면역 유도를 통한 장티푸스 특이 IgA 항체 양전율과 백신 투여 후 발생한 이상 반응을 조사함으로 백신의 면역원성과 안전성에 대해 알아보고자 이 연구를 시행하였다. 재료 및 방법 : 2001년 7월부터 2002년 3월까지 고려대학교 의과대학 안산병원에서 건강한 6세 이상의 소아, 청소년 및 성인 지원자를 93명을 모집하여 장티푸스 생균 백신(지로티프 캅셀, 보령신약)을 1캅셀씩 2일 간격으로 3회 경구 투여하였다. 투여 시작 후 6, 8, 10일째에 혈액을 채취하여 혈중에서 장티푸스 특이 IgA 분비세포를 측정하는 ELISPOT(enzyme-linked immunospot) 방법으로 면역형성 유무를 검사하였다. 또한 2001년 7월부터 2001년 11월까지 고대안산병원을 포함한 전국 12개 기관에서 모집한 465명의 소아 및 성인남녀 지원자를 대상으로 백신 투여 후 발생한 이상 반응을 조사 분석하였다. 결과 : 1) 지원자 중 항체 양전율 연구를 마친 사람은 6-15세의 16세미만군 42명(남 : 22명, 여 : 20명), 16세이상군 51명(남 : 17명, 여 : 34명), 합계 93명(남 : 39명, 여 : 54명)이었으며, 평균 연령은 16세미만군 11.1±2.5세, 16세이상군 31.6±9.8세였다. 이상 반응 조사가 완료된 사람은 465명(남 : 187명, 여 : 278명)이었으며, 평균 연령은 31.3±16.9세였다. 2) 16세미만군의 항체 양전율은 73.8% (31/42명), 16세이상군의 양전율은 86.3%(44/51명)였으며, 양 군간에 통계적으로 유의한 차이는 없었다. 성, 연령, 알레르기력, 기존 질환, 병용약물 등 대상자의 제반 배경 인자 중에서 통계학적으로 유의하게 양전율에 영향을 미치는 요인은 없었다. 3) 이상 반응의 발현 증례율은 8.6% (40/465명)였으며 증상별로는 복통, 설사, 구역 등 위장관계 이상이 6.5% (30/465명), 무력감, 발열 등의 전신 이상이 1.3% (6/465명), 두통이 0.6% (3/465명), 피부발진이 0.2% (1/465명)에서 나타났다. 백신 복용 횟수에 따른 이상 반응 발현율은 1차 복용 후 5.2% (24/465명), 2차 복용 후 4.5% (21/462), 3차 복용 후 2.6% (12/461)로 처음 복용 후 유의하게 높았다(P<0.05). 대상자의 제반 배경 인자 중에서 통계학적으로 유의하게 이상 반응 발현율에 영향을 미치는 요인은 없었다. 결론 : 경구용 약독화 장티푸스 생균 백신은 장점막 면역유도를 통한 우수한 면역원성을 가지고 있으며, 이상 반응 발생률이 낮고 이상 증상이 경미하여 소아 및 성인 모두에 안전한 백신으로 판단된다. Background : This study is aimed at evaluating immunogenicity by measuring immunoglobulin A (lgA) seroconversion rate through common mucosal immune system and adverse reactions after vaccination of oral live attenuated Salmonella typhi (S. typhi) Ty21a vaccine in Korean population. Methods : A commercially available oral live attenuated vaccine of S. typhi strain Ty21a (Zerotyph® capsule, Boryung Biopharma Co., Seoul, Korea) was given to volunteers, children above 6 years, adolescents, and adults who have never infected with S. typhi nor received S. typhi vaccination. The vaccines were given in three doses, with two day interval between the doses. Seroconversion was determined by ELISPOT (enzyme-linked immunospot) assay. Adverse reactions after vaccination were evaluated in 12 institutions by direct interviewing with vaccinees. Results : A total of 93 volunteers for evaluation of seroconversion were enrolled. Seroconversion rate in the the below 16 year-old group was 73.8% (31/42) and that of over 16 year-old group was 86.3% (44/51), which was not statistically different. Adverse reaction were found in 8.6% (40/465). Gastrointestinal symptoms were most common (6.5%, 30/465). Adverse reactions were found in 5.2% (24/465) after 1st administration, 4.5% (21/462) after 2nd, and 2.6% (12/461) after 3rd. Frequency of adverse reactions was significantly higher after 1st administration (P<0.05). Conclusion : Oral live attenuated S. typhi vaccine, Zerotyph® capsule, had good immnuogenicity and safety through intestinal immune system.

To investigate the prognostic factors for the survival of transplanted kidney in patients with end-stage renal failure, 59 cases of renal transplantation from September 1986 to Feburary 1997 in Chungnam National University Hospital were analyzed retrospectively. The results were as follows: 1)The mean age of recipients was 33.8 years and that of doners was 38.9 years. The male to female ratio of recipients was 2.5:1, and that of donors was 1.03:1 2) Living related donore(LRD) were 79.6% and living non-related donors were 20.3%. The HLA-identical donors(ID) in LRD were 18.7% and HLA-haploidentical donors(HID) were 61.0%. In living non-related donors(LNRD), mean matched HLA-AB antigens were 1.56 and mean matched HLA-DR antigens were 0.56. 3) The average 5-year patient survival fate was 94%, and average 5-year graft survival rate was 70%. The 5-year graft survival fate of HLA-ID was 100%, and those HLA-HID and LNR were 70% and 36% respectively. 4) Total 33 episodes of acute rejection were found in 45.8% of transplanted patients. The number of acute rejection episode did not show significant difference between LRD and LNRD(P > 0.05). There was no significant difference in MLC between two groups(p > 0.05). 5) In comparison between the 18 patients who lost their graft function in 5 years and 17 patients who are maintaining graft function for more than 5 years, MLC was significantly lower in patients with functioning graft than of patients with non-functioning graft (p < 0.05). The number of rejection episode was also lower in patients with functioning graft than that of the patients with non-functioning graft(p < 0.05). However, there were no significant difference in recepient and donor age and history of pre-transplantation donor specific transfusion between two groups. With the results above, we can speculate that adequate donor selection according to good matched HLA typing and low MLC is very important for graft survival in renal transplantation. Prevention and treatment of acute rejection in renal transplantation is also na important factor for graft survival.

Recently, the number of patients who infected HIV virus are increasing dramatically and the situation becomes a serious social problem today. Because a vaccine or cure for AIDS is not available nowadays, the prevention is very important, especially for young age. The main objective of this study was undertaken to develop the educational programs for AIDS prevention. For this, a survey was conducted on 519 high school students in Sunchon during November 14 to November 17, 1994 with a questionnaire. The results of this survey were summarized as follows. 1. Most of the respondants got the informations related to AIDS through mass-media such as TV, video programs, magazines or newspapers. but, they want to learn about AIDS at school or health agencies. 2. The level of the students' AIDS knowledge was relatively low. 3. Positive attitude was found for the prevention of AIDS but negative attitude for the social interaction with AIDS patients. 4. Most of the respondants thought that the government must play a role for the prevention of AIDS much more than these days. Following suggestions were indicated. 1. The educational programs for AIDS using Audio & Visual media should be developed for a student to use it easily. 2. The educational/training program for school teachers and health agency staff should be provided. Future research and survey about knowledge, attitude and behavior related to AIDS should be conducted for the other groups.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

효모에는 5가지 종류의 thiol peroxid se 동위효소들인 cytoplasmic TPxⅠ, cTPxⅡ, cTPxⅢ, mitochodrial TPx (mTPx), 및 nuclear TPx (nTPx)가 존재하고 있다. 특히, cTPxⅡ는 다른 효모 TPx들과 비교해 볼 때 매우 낮은 peroxidase 활성을 보이나, cTPxⅡ를 제거한 cTPxⅡ mutant 균주는 심하게 성장이 저해되는 특징을 보인다. 본 연구에서는 효모에서의 cTPxⅡ의 생리학적 기능을 밝히는 연구의 첫 과정으로 cTPxⅡ와 상호 작용하는 단백질을 탐색하였다. Sacchromyces cerevisiae genomic DNA library에서 yeast two-hybrid system을 이용하여 cTPxⅡ와 상호 결합하는 단백질을 탐색하여 그 단백질들의 기능을 연구하여, 궁극적으로 cTPxⅡ의 생리기능을 밝히는데 이 연구의 목적을 두었다. There are five isoforms of thiol peroxidase in yeast. Each isoform was named after its subcellular localization such as cytoplasmic TPxⅠ, cTPxⅡ, cTPxⅢ, mitochondrial TPx (mTPx), and nuclear TPx (nTPx). Recently, we reported that unlike other TPx null mutants, cTPxⅡnull mutant showed a slow-growth phenotype. This observation suggests that cTPxⅡ might be involved in yeast cell growth. In this study, for a first step toward to investigate the physiological function of cTPxⅡ in yeast, we have identified a novel interaction between cTPxⅡ and various proteins by using the yeast two-hybrid system.
