Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

공기증신우신장염은 신실질의 괴사와 자발적인 공기 형성과 연관된 드문 감염질환이다. 대부분 혈당이 잘 조절되지 않는 당뇨 환자들에게서 발생하며 드물게 요로 폐색, 요로 결석, 종양 등에서도 발생한다. 과거 초기의 수술적 치료가 우선시 되었으나 최근에는 항생제 및 조기 진단으로 인해 내과적 치료만으로 성공한 사례가 증가하고 있다. 저자들은 현성 당뇨병이 없었던 알코올 간경화증 환자에서 발생한 공기증신우신장염을 내과적 치료 및 경피적 배농술만으로 치료한 예가 있어 보고하는 바이다. Emphysematous pyelonephritis is an uncommon infection of the kidney associated with parenchymal necrosis and spontaneous gas formation. Most cases occur in diabetic patients and rarely in urinary tract obstruction, stone or tumor. At past, surgical treatment was prior to internal treatment, but recently, successful cases of internal treatment have increased because of the development of antibiotics and early diagnosis. We report an emphysematous pyelonephrtis in 61 years-old non-overt diabetic woman with alcoholic liver cirrhosis, successfully treated by antibiotics and percutaneous drainage.

The objectives of this study were to review the concepts of rural and urban society theoretically and to search for the socio-ecological characteristics of the typical rural area, Myon, in terms of regional industrialization. The research areas were 353 Myons in 36 Guns which were sampled by stratified random sampling methed. The major findings of the study were as follows; 1) The average population of Myon, the hinterland, were 5,879 and the average households were 1,554. 2) Most of Myon had the characteristics of rural society which had over 70% of farm population rate. One Myon had 24 villages and each village held 68 households and 256 persons on the average. 3) The average area of Myon was 63.2㎢. However, the high standard deviation insinuated that there were great disparities in area between Myons. 5) The distance from Myon-office to rural center was 17Km on the average. 6) Synthetically, further research should be followed to identify whether the Myon area is suitable for a unit of rural human settlement planning area to demarcate as a self-sufficient human settlement area.

학생들의 인지발달을 촉진시켜 학습효과를 높이려고 개발된 CASE 프로그램의 효과를 조사했다. 중학교 1학년(841명) 학생들이 연구에 참가하였으며, 같은 분량의 시간동안 실험반에서는 교육과정에 따른 과학 교과 수업과 '생각하는 과학' 활동을 병행하였고, 통제반에서는 과학교과 수업만을 수행하였다. 연구 초기에 논리적 사고력 검사(SRT II)를 이용하여 집단의 동질성을 비교하고, 2년 동안 실험반에 CASE프로그램을 처치한 후 이질동형겸사도구인 SRT VII을 이용하여 처치별, 성별, 인지수준별 인지가속에 대한 효과를 조사했다. CASE 프로그램에 의한 중학생들의 인지발달 가속효과는 중간검사에서는 보이지 않았으나, 사후검사에서 상당히 큰 것으로 확인되었다. 성별에 따라 CASE 프로그램의 효과를 비교한 결과 남??여 중학생들 모두에게 유의미한 인지가속이 이루어진 것으로 나타났다. 남학생들 보다 여학생들의 인지수준이 더 발달된 것으로 밝혀졌으며, 처치와 성별간 상호작용 효과는 나타나지 않았다. 학생들의 사전 인지수준에 따라 CASE 프로그램의 효과를 분석한 결과, 모든 인지수준에서 처치효과가 뚜렷하게 있었으나 특별한 경향성은 나타나지 않았다. 특히 초기 구체적 조작기(ES=1.1.)와 전조작기(ES=1.07), 그리고 구체적조작 후기(ES=1.01) 학생들에게 상당히 큰 효과가 있었다. 이상과 같은 CASE 프로그램의 성공적인 결과는 현행 우리나라 과학교육과정 개정과 교수방법 개선에 시사하는 바가 많다. In an attempt to accelerate the development of formal reasoning ability of students, 'Thinking Science' activities developed by the Cognitive Acceleration through Science Education(CASE) project were implemented to 841 students in 7th grade aged 12+ in six middle schools over a period of two years. Homogeneity between the CASE group and control group was tested with SRT Ⅱ, while the improvement of formal reasoning ability of the students was tested with SRT Ⅶ. The results were analyzed by treatment, gender, and cognitive levels of the students. Statistically significant gains were shown in the CASE group compared with those in the control group. Cognitive level of girls in the CASE group significantly increased as compared with the control group, while there was moderate effect in boys. These results implied that the thinking science activities were effective in cognitive acceleration of girls aged 12+. It was shown that much more CASE students in pre or concrete operational level shifted. to formal operational level as compared with the control group while there were significant effects in all levels (ES=0.31∼1.10) without showing any tendency.

The purpose of this study was to develop funtional lab gowns in the view of safety and work efficiency. As the first step of this study, we surveyed on satisfaction rates, preferences and inconvenience items in regard of lab gowns. The data was obtained from 138 graduate students specialized in science and 113 medical students. Respondents answered that the first purpose of wearing lab gown was to protect body from danger. Wearing frequency followed with 'always', 'as possible as', and then 'sometimes' Forty-five percentage of respondents answered that they didn't wear lab gowns often in summer because of hot weather. The contaminated or damaged parts of lab gowns followed with cuffs, abdomen, thigh, lower part, and then chest. Washing frequency followed with 'once a month', 'once per six months', and then 'more than once a week'. There were significant differences in normal wearing frequency, wearing frequency by season and washing frequency due to major. There were no significant difference by sex and major in all questions. In regard of the protective capacity of current lab gowns, most respondents answered that 'It's normal' (60%), ‘It's enough'(21%), so that they didn't show much dissatisfaction. Forty-three percentage of respondents were not satisfied with cuffs. Respondents answered that the cuffs were in danger and inconvenient because of broad cuffs. In regard of color, preference for white were high and followed with ivory, light sky, light green, and then light pink. Materials of current lab gowns were cotton/polyester or polyester 100%. Sixty-eight percentage of respondents were satisfied with that and others were not. The reasons for dissatisfactions were as follows; those materials were not protective to chemicals thoroughly enough. Cotton/polyester materials were heavy. Wearing sensation of polyester 100% was not good.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

접속방법에 따른 접지도체 굵기 제안식

崔洪圭,吳廷錫,宋榮朱 弘益大學校 産業技術硏究所 2004 産業技術 Vol.14 No.-

접지도체의 굵기를 결정하는 국외 규격은 재료의 특성값인 물리적 정수까지 적용하여 광범위하게 적용할 수 있는 반면 수식이 복잡한 문제점이 있고 JIS와 국내규격은 수식은 간단하나 제약조건이 많은 문제점이 있다. 또한, 접지도체의 접속방법에 따라 최대허용온도가 다르게 적용되므로 접지도체 굵기 산정 방식이 복잡하고 적용 방법이 상이하여 시공현장에서 엔지니어들이 적용하는데 많은 어려움이 있다. 따라서, 본 논문에서는 새로운 접지도체 굵기 산정방식을 제시하고 접속방법에 따른 접지도체 굵기 산정 간이식을 제시한다.

최정화,이주영,김소영 한국의류학회 2004 한국의류학회지 Vol.28 No.2

The purpose of this study was to evaluate thermal properties of lab gowns developed from the point of safety and work efficiency. We evaluated thermal and subjective responses of subjects wearing functional new lab gowns(Type B, C, D) and a popular lab gown on the market(Type A). Type B was a new lab gown made of woven fabric with functional cuffs. Type C was a new apron made of woven fabric with arm protectors. Type D was a new lab gown made of non-woven material with functional cuffs and openings around the armpits. Temperature in the climatic chamber was set at 19℃as an indoor temperature in winter and at 24℃ in summer. There were no significant differences in rectal temperature and heart rate among four types of gowns and between two air temperatures for 120min. Mean skin temperature was much higher in the type A and B than in the type C and D(p<.05). In the 19℃air, clothing microclimate temperature on the back was the highest in the type B and was the lowest in the type C (p<.05). Clothing microclimate humidity was not significant differences among gowns. In subjective responses, subjects perceived that Type B was the warmest gown in the 19℃ and the hottest and more humid in the 24℃ than other gowns. Inversely, type C was the coolest gown among four gowns. Both in the 19℃and in the 24℃, the Type D had gained most responses of being comfortable. In conclusion, the temperature difference of 5℃ was more of an influencing factor than the difference from four types of lab gowns. Secondly, we recommend the manufacturers to make lab gowns with functional cuffs for safety purposes. Thirdly, the spread of the type of apron with arm protector will contribute to increase of the frequency of wearing in summer. Fourthly, it is necessary to study continuously about lab gowns with non-woven materials for researchers exposed to toxic chemical and biological materials.
