Background: Nail can be affected by trauma, infection, and systematic disorders. In particular, the toe nails are exposed to the repeated and cumulative minor traumas, which usually result in thickened, splitted, and discolorated nails. Considering these, it can be inferred that the long second toe can be related to various nail and skin changes by repeated minor traumas such as friction in shoes, but the study or report on this topic hasn’t been done yet. Objectives: The purpose of this study was to introduce various nail and skin changes on long second toe. Methods: We analyzed the kinds of nail/skin changes of 50 patients with long second toe, enrolled at Pusan National University Hospitals (Busan and Yangsan) from 2013 to 2018. Results: There was no significant difference in the incidence of left and right toe and toenail, and 7 (14%) patients presented bilateral distribution. The most common nail change on long second toe was melanonychia (23, 46%), followed by subungual hematoma (15, 30%), onycholysis (2, 4%), subungual hyperkeratosis (2, 4%), onychomadesis (1, 2%), and retronychia (1, 2%). The most common skin change was corn (9, 18%), followed by paronychia (2, 4%). Twenty (20/50, 40%) patients also had other toe or toenail changes. Among them, the most common site was big toe/nail (13, 62%), and the most common change was subungual hematoma (8, 42%). Conclusion: Through this study, the dermatologists can recognize and diagnose the nail and skin changes of long second toe.

Objectives : Oxidized LDL is thought to play a key role in atherogenesis. Among their wide variety of biological properties, oxidized LDL injures the endothelium as an early event of atherogenesis. However, the mechanisms by which oxidized LDL injures endothelial cells are not definitely known. In order to evaluate the involvement of GTP-binding protein on the mechanism of apoptosis, we studied the effects of pertussis and cholera toxin on oxidized LDL-induced apoptosis in bovine aortic endothelial cells(BAECs). Methods : Oxidized LDL elicited apoptosis in cultured BAECs as shown by characteristic morphological and biochemical changes. Chromatin condensation and nucleus fragmentation were visualized by using fluorescence microscopy of intact cells staining by acridine orange/ ethidium bromide. DNA fragmentation was quantified by an ELISA with specific antibody for bromodeoxyuridine- labelled DNA fragments and confirmed with DNA ladder formation. Results : Studies using a combination of bacterial toxins which change the function of GTP-binding protein suggest that oxidized LDL-induced apoptosis was regulated by GTP-binding protein. Oxidized LDL-induced apoptosis was not changed by pretreatment of BAECs with pertussis toxin. In contrast, pretreatment with cholera toxin completely prevented the oxidized LDL- induced apoptosis. Conclusion : These results show that oxidized LDL induces apoptosis of BAECs and suggest that cholera toxin-sensitive G-proteins are involved in signal transduction of oxidized LDL-induced apoptosis of BAEC.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

환자가 의료기관을 선택할 때 작용하는 요인은 매우 다양하며 이에 대한 많은 연구들이 있었으나 대부분 외부적인 요인에 대한 연구가 많았고 의료기관 선택 시 환자의 정신-심리학적인 면에 대한 정보는 부족한 실정이다. 이에 본 연구에서는 비교적 선택진료(elective treatment)의 측면이 많은 교정치료를 받기 위해 치과의원과 대학치과병원에 내원한 환자들이 의료기관을 선택하는 여러 요인들 중 정신-심리학적 요인을 알아보기 위해 인간의 행동을 예측하는데 유용하다고 알려진 통제소재(Locus of control)검사를 이용하였다. 교정치료를 목적으로 서울대학교 치과병원에 내원한 환자 934명 및 치과의원에 내원한 환자 1466명을 대상으로 내외통제소재검사를 시행한 결과 대학치과병원 교정환자들이 치과의원 교정환자에 비하여 외적통제 경향이 높았으며 이러한 결과에 비추어 대학치과병원 교정환자들이 치과의원 교정환자들에 비해 의료진의 권위에 의존하는 정신-심리학적 경향이 존재하는 것으로 나타났다. Objective: Mary factors are considered when a patient chooses the type of dental institution they wish to receive treatment from. Numerous studies have been conducted regarding this issue. However, more research is needed in analyzing the patient's psychological aspects when he/she decides to choose the dental institution they wish to receive treatment from. Methods: A locus of control test was utilized to analyze the psychologica1 aspects in orthodontic patients of a university denta1 hospital and a private dental clinic. The locus of control test is known to be useful in predicting a human being's behavior Both intrinsic and extrinsic locus of control tests were carried out in 934 orthodontic patients attending Seoul National University Dental Hospital and 1466 orthodontic patients from a private dental clinic. Results: The orthodontic patients at the university dental hospital showed a stronger extrinsic locus of control compared with those from the private dental clinic. Conclusion: The orthodontic patients at the university dental hospital value the doctor as the authority figure and the treatment quality more than those at the private dental clinic.

장경희,류동렬,박성하,박병규,이준구,염준섭,최영화,송영구,김현숙,정윤섭,김준명 대한감염학회 1998 감염 Vol.30 No.4

목 적 : 장티푸스는 체액의 세균배양검사에서 Salmonella typhi의 분리로 확진하지만 조기진단을 위해서는 혈청학적인 검사가 도움이 된다. 저자 등은 1989년 이후 장티푸스진단에 S. typhi의 Vi항원을 이용한 간접형광항체법 (Vi-indirect fluorescent antibody test : Vi-IFAT)을 도입하였다. 이에 지난 7년간의 검사결과를 토대로 Vi-IFAT의 민감도 및 특이도를 규명하고자 하였다. 방 법 : 1989년부터 1996년까지 연세대학교 의과대학 세브란스 병원에 발열을 주소로 내원하여 Vi-IFAT가 의뢰된 환자 중 발열의 원인이 확진된 744명의 환자를 대상으로 하였으며, Vi-IFAT에 있어서 양성반응은 1:64이상으로 하였다. 결 과 : 1) 세균배양검사에서 확진된 장티푸스 환자 178예 중 168예에서 양성반응을 보여 민감도는 94.4%이었다. 항체가는 1:64가 89예, 1:128이 36예, 1:256이 27예, 그리고 1:512가 16예이었다. 위음성이었던 10예의 항체가는 1:32가 7예, 1:16이하가 3예이었다. 2) 발열을 주소로 내원한 환자 중 장티푸스 이외의 다른 질환으로 확진된 566예 중 538예에서 음성반응을 보여 특이도는 95.1%이었다. 항체가는 1:32가 117예, 1:16이하가 421예이었다. 위양성이었던 28예의 항체가는 1:64가 23예, 1:128이 5예이었으며, 장티푸스 이외의 살모넬라증이 4예, 요로계감염이 10예, 소화기계감염이 6예, 호흡기 계감염이 5예, 악성 종양이 2예, 그리고 바이러스 감염이 1예이었다. 3) Vi-IFAT 양성인 196예 중에서 장티푸스는 168예로 양성예측율은 85.7%이었으며, Vi-IFAT 음성인 548예 중 장티푸스 이외의 발열질환은 538예로 음성예측율 98.2%이었다. 4) 배양검사와 Widal test 사이의 일치율 (Kappa value)는 0.28로 poor agreement를 보였으며 Vi-IFAT와 Widal test 사이의 Kappa value는 0.74로 good agreement를 보였다. 그러나 배양검사와 Vi-IFAT 사이의 Kappa value는 0.86으로 excellent agreement를 보여 일치율이 가장 높은 검사는 배양검사와 Vi-IFAT라 할 수 있겠다. 5) 장티푸스 환자에 있어서 Vi-IFAT의 양성율은 발열기간이 1중 미만인 환자에서는 68%, 1내지 2주인 환자에서는 89.5%, 2주이상인 환자에서는 100%이었다. 결 론 : Vi 항원을 이용한 간접형광항체법 (Vi-IFAT)은 장티푸스 진단에 높은 민감도 및 특이도를 가지며, 또한 조기진단에 있어서도 임상적으로 유용함을 확인할 수 있었다. Background : Typhoid fever is diagnosed by culture or serological study. The confirmative diagnosis of typhoid fever is made by culture of the causative organism usually from body fluids. Serological test is a supportive diagnositic tool, which is useful for early diagnosis. In Severance Hospital, Vi-indirect foluorescent antibidy test(Vi-IFAT) using the Vi-antigen of Salmonella typhi has been used in the diagnosis of typhoid fever since 1989. We investigated the test results from the past 7 years, in order to clarify the sensitivity and specificity of Vi-IFAT. Methods : A retrospective study was done on patients whose chief complaint was fever and who were tested using Vi-IFAT in the Severance Hospital from 1989 to 1996. The positive value for Vi-IFAT was defined as 1:64 or higher. Results : The sensitivity and specificity of Vi-IFAT for typhoid fever was 94.4% and 95.1%, respectively. The positive and negative predictive values were 85.7% and 98.2% respectively. Positive rates of Vi-IFAT after fever onset increased with time and 68% were positive before the first week. From the first to the second week, 89.5% were positive and after the second week, 100% were positive. Conclusion : Vi-IFAT is not only a valuable serologic test for the diagnosis of typhoid fever, but also useful in the early diagnosis of the disease.

새로운 저비용 고효율 조류 피해 방지법의 개발을 위한 기초자료를 얻기 위하여, 현재 사과, 배 과수원에서 사용되고 있는 조류피해 방지 방법들의 정확한 효과를 서로 비교 검토하고, 아울러 충북지역 과수 재배 농가들을 대상으로 유해조류에 의한 피해 실태와 경제성 있는 조류 피해방지 방법에 대한 설문조사를 병행 실시한 결과는 다음과 같다. 1. 조류피해는 방조망 설치에 의해서만 완전히 방지할 수 있었으며, 조류 피해율별 손익계산 결과를 참고하여 이익이 있을 때는 표준방조망을 설치하고, 그렇지 않을 경우에는 설치비가 저렴하며 농가에서 간단히 시공할 수 있는 간이방조망 설치가 더 경제적인 것으로 판단되었다. 도내 과수 농가의 조류피해는 지역 간에 큰 차이가 있었으며, 음향적 방제인 버드가드와 보호봉지인 망사봉지에 의한 방제가 가장 효과적이었다. 그러나 버드가드는 높은 설치비용이 문제되므로, 퇴치 효과가 비슷하거나 더 우수하면서 저렴한 한국식 음향 기구를 개발할 필요가 있는 것으로 판단되었다. 보호봉지인 UV 봉지와 플라스틱 보호캡 및 망사봉지 처리는 품종에 관계없이 피해를 현저하게 감소시켰으나, 과실의 착색 등 품질에 미치는 영향에 대해서 추가적인 연구와 검토가 필요한 것으로 생각되었다. To obtain basic data for low cost-high efficiency control methods for bird damage, the available control methods currently in use mostly in Chungbuk Province were tested on site, and the control efficiency was compared. Also, a comprehensive survey of actual bird damage and the control methods on model apple and pear growers in Chungbuk Province was conducted. The results are summarized as follows. The perfect control for bird damage was possible only through bird net, it was recommended that profit-and loss account must be considered before installing bird net, and when the 'standard bird net' does not come up to break-even point, more economic and convenient 'simplified bird net' should be a alternative. Actual extent of bird damage varied according to the locality, and imported acoustic apparatus BirdGard^R, development of our own system with superior or same quality and reasonable price is necessary. Fruit bags such as UV bags, plastic protective caps, and net bags were highly effective for bird damage control, irrespective of fruit species and cultivar, but further study to resolve some problems such as poor coloration caused by bagging is necessary.

점증부하운동후 휴식유형에 따른 운동후 초과산소소비량에 미치는 영향

김구,유영창,박양순 圓光大學校 附設 體力科學硏究所 2003 體力科學硏究 Vol.26 No.1

The purpose of the this study is to explore the relationship between the excess post-exercise oxygen concentration(EPOC) during the restoration stage after an incremental loading exercise. Subjects of this study are 14 students enrolled in S University who do not exercise regularly. Seven of them were assigned to the group of dynamic resting and remaining 7 to that of static resting. From the analysis into the measurement, following conclusions could be drawn: There was a significant difference in excess post-exercise oxygen concentration(EPOC) after an incremental loading exercise depending on the types of rest(p<0.1). The dynamic resting required higher consumption of oxygen than the static one during the inital restoration stage after exercise, with the significant difference appearing 15 minutes after the start of restoration(p<.01). In terms of □_(E), there was a significant difference among the resting types. The dynamic resting method indicated generally higher ventilation rate than the static one until 15 minutes after the end of exercise, with the significant difference found around 20 minutes after the start of restoration(p<.01). Regarding the RER, there was a signifincant difference by the resting types(p<.01). The dynamic resting type was found to have lower exchange rate of respiration than the static one, with the significant difference seen around 5 minutes since the start of restoration(p<.01). In sum, there was a significant difference of response in physiological variants depending on the types of resting after an incremental loading exercise. That is, the dynamic resting method evidenced more increase in excess post-exercise oxygen concentration(EPOC) and □_(E), lower RER after exercise than the static resting method. This result suggested that the dynamic resting method after the incremental loading exercise might be regarded as a rest to ensure the fastest satisfaction of the physiologic requirements necessary to restore homeostasis after exercise in comparson with the static resting method. Accordingly, more attention should be paid to the importance of cool down after exercise.

Objective : This study is a follow-up of a first survey of 200 North Korean defectors who entered South Korea in 2001. The purpose of this study is to examine changes in the current prevalence of partial PTSD and full PTSD after 3 years and to evaluate related factors. Methods : This study followed up on 151 of the 200 North Korean defectors from our first survey. 20 interviewers conducted face-to-face interviews and assisted defectors in completing a self-report assessment. The traumatic events which participants with chronic PTSD and delayed onset PTSD experienced were then examined. Results : Over the 3 years, the current prevalence rate of partial PTSD was reduced from 31.8% to 5.3%, and the current prevalence rate of full PTSD was reduced from 27.2% to 4.0%. Of particular interest was that 88.8% of those diagnosed with full or partial PTSD in the first survey had recovered after 3 years. Conclusion : The current prevalence rate of partial and full PTSD rapidly decreased during 3 years.

α-黃銅粒界 周圍에서의 溶質 分布 計算

金龍成,崔俊浩,張賢球 成均館大學校 科學技術硏究所 1990 論文集 Vol.41 No.1

Solute distribution on the ∑3 [110] and ∑5 [100] tilt boundary in a-brass of Cu-Zn binary system was studied. In calculating the amounts of solute segregated around the grain boundary, the regular solution theory was applied to define atomic interaction and coincidence site lattice model was used for grain boundaty structure. The results are summarized as follows : 1) Around the gtain boundary of α-brass, the zinc concentration profile curve shows a damped oscillation because of the ordering tendency in a-brass which has a negative value of the heat of mixing. 2) In Zn profile curves, the width of damped oscillation in ∑5 boundary is wider than that in ∑3 boundary because of the different number of broken bonds in each boundaries. 3) As the excess energy of ∑5 boundary is larger than that of ∑3 boundary, solute concentration in ∑5 boundary is higher than that in ∑3 boundary.
