Singapora shinshana is a leafhopper native to mid-Asia with a specific host range and is one of the least studied species within the genus. Recently, the species has been found to cause significant damage to host plants including ornamental trees, normally inflicted by its sucking behavior. This study uncovered more details on host and season preference of S. shinshana, damage potential and symptoms caused by its feeding behavior on ornamental trees in Korea, in addition to other records of other leafhoppers of economic importance. During the sticky trap survey period from 2017 to 2019, 12 leafhopper species were recovered from the eight selected ornamental tree species. Singapora shinshana was the most dominant species, constituting 94.8% of the total collected leafhopper population; with its highest incidence observed on Prunus serrulata, followed by Elaeagnus umbellata and Pseudocydonia sinensis. The high abundance on P. serrulata correlated with high damaged leaf percentages of 94.2%, 95.2%, and 98.1% in October 2017, 2018, and 2019, respectively. Interestingly, in terms of damaged leaf percentage, Rosa hybrida and Zelkova serrata were the second and third most damaged hosts despite the significantly lower population of the leafhopper on these trees. Furthermore, S. shinshana counts increased from late-July to late-September, with the peak evident during early August. Prunus serrulata can therefore be taken as one of the main host plants of S. shinshana. However, the potential of the host to suffer damage is not limited to population densities of the pest alone but also susceptibility and tolerance of the host plant.

연구목적 : DSM-Ⅲ-R의 개정판이라기 보다는 새로운 진단 기준으로 간주될 정도였던 DSM-Ⅳ의 출현은 정신장애의 진단분류체계에 매우 큰 영향을 미쳤다. DSM-Ⅳ의 변화를 반영하여 정신과적 진단을 내릴 수 있도록 DIS-Ⅲ를 개정하여 DIS-Ⅳ가 개발되었다. 본 연구는 국내에서의 정신의학적 연구를 더욱 활성화하고 활발하게 국제 공동연구가 이루어질 수 있도록 DIS-Ⅳ 한국어판을 개발하고 이를 표준화하는 데 그 목적이 있다. 방 법 : 번역 위원회에서 번역, 역번역, 어의적 정확성 확인, 한국어 용법에 맞도록 수정한 후 예비 연구를 거쳐 한국어판 DIS-Ⅳ가 완성되었다. 의과대학생 4명에게 Washington University DIS-Ⅳ training course와 동일한 내용과 방법으로 교육을 실시하였다. 두 명의 조사요원들이 한 환자를 DIS-Ⅳ를 사용하여 동시에 검사한 후의 진단을 비교하여 검사자간 신뢰도를 측정하고, 정신과 의사가 독립적으로 DIS-Ⅳ를 사용하여 검사한 후의 진단과 비교하여 절차 타당도를 평가하였다. 조사 대상은 2000년 1월부터 8월까지 2개 대학 병원 정신과 및 국립감호정신병원에서 치료중이던 환자 124명이었다. 결 과 : 평가자간 신뢰도의 kappa값 평균은 0.74였다. 양극성 Ⅰ장애, 범불안장애, 우울장애, 강박장애, 반항장애, 동통장애, 병적 도박, 외상후 스트레스 장애, 특정공포증 및 대부분의 물질 사용 혹은 관련 장애의 kappa값이 0.7 이상이었다. 정신과 의사의 진단과 조사요원의 진단의 일치도를 비교한 절차 타당도를 살펴보면 다음과 같다. 전체적인 sensitivity는 67.6%, specificity는 98.3%, kappa 값은 0.69이었다. 물질 사용 장애 및 물질 관련 장애의 SE는 79%, SP는 98.6%, kappa 값은 0.77이었다. 이를 제외한 나머지 정신 장애의 SE는 60.5%, SP는 98%, kappa 값은 0.64이었다. 본연구의 결과는 Robins 등에 의해 최초로 보고된 DIS의 신뢰도 및 타당도와 거의 비슷한 수준이었다. 결 론: 한국어판 DIS-Ⅳ가 높은 신뢰도와 타당도를 지닌 것으로 생각된다. 이 도구를 통해 물질 사용 및 관련 장애를 타당도와 신뢰도 높게 진단할 수 있다는 점이 매우 중요하다. 향후 정신장애의 진단 능력을 향상시키고 임상연구를 활성화하고 국제적인 학술적 교류를 늘리는데 일조할 수 있을 것이다. Objective : Appearance of DSM-Ⅳ has influenced greatly on the nosological classification of mental disorder, not considered as revised one of DSM-Ⅲ-R but a new criteria. DIS-Ⅳ has been developed after revision of DIS-Ⅲ in consideration of various changes in DSM-Ⅳ. This study is to develop and validate the DIS-Ⅳ, Korean version to activate Korean psychiatric research much more and to modivate more frequent international collaborative study. Method : Translation committee produced DIS-Ⅳ, Korean version through all the procedures of translation, back-translation, confirmation of retained original meaning of the English version, adaptation to Korean linguistic usage and preliminary study. Four medical students were trained during DIS-Ⅳ training course that retained the same contents and methods as of Washington University. Inter-rater reliability was measured by comparison between two diagnoses made from two interviewer who rated one patient at the same time. Procedural validity was measured by comparison between lay-interviewer's diagnosis and psychiatrist's diagnosis which were made after independent DIS-Ⅳ using interview. Subjects were 124 patients who were being treated at two University Hospital and National Forensic Psychiatric Hospital between January, 2000 and August, 2000. Results : Average kappa value of inter-rater reliability was 0.74. Diagnoses showing over 0.7 in kappa value were bipolar I disorder, generalized anxiety disorder, depressive disorder, obsessive-compulsive disorder, oppositional defiant disorder, pain disorder, pathological gambling, post-traumatic stress disorder, specific phobia and almost all substance use disorder or substance-related disorder. Procedural validity, that compared lay-interviewer's diagnosis and psychiatrist's diagnosis, were as follows: For all diagnoses, sensitivity, specificity and kappa were 67.6%, 98.3% and 0.69. For diagnoses of substance use disorder or substance- related disorder, sensitivity, specificity and kappa were 79%, 98% and 0.77. For other diagnoses except substance use disorder or substance- related disorder, sensitivity, specificity and kappa were 60.5%, 98% and 0.64. This results are almost at the same level as that of Robins and her colleagues who tirst reported reliability and validity of DIS. Conclusion : We think that DIS-Ⅳ, Korean version has higher reliability and validity. It is very important that diagnoses of substance use disorder and substance-related disorder can be made reliably and validly by this instrument. We expect that it can help to improve diagnosability of mental disorder, activate clinical research and increase international scientific communication.

박일,임영국,최성도,임현성,정종훈,문철웅 朝鮮大學校 附設 醫學硏究所 1992 The Medical Journal of Chosun University Vol.17 No.1

호흡기 증상과 급성신부전증이 발생된 환자에서 혈액검사, 혈청학적 검사, 방사선학적 검사, ANCA test 및 신생검을 통하여 Wegener씨 육아종증을 경험하였기에 문헌 고찰과 함께 보고하는 바이다. 본질환이 재발하는 경우는 cyclophosphamide에서 azathioprine으로 치료약을 바꾸었을때나 특히 ANCA 반응이 양성으로 지속시 발생한다. Godman과 Churg는 상기도의 괴사성 육아성 병변, 하기도의 괴사성 혈관염, 국한성 신사구체염을 진단의 지표로 삼았다. 특히 상기도 점막의 생검 소견상 괴사성 육아성 혈관염이 보이면 일단 본 증을 의심하고 폐 생검과 신 생검이 필요로 한다. Wegener's Granulomatosis is an uncommon disease which is characterized by granulomatous vasculitis of both lung and kidney. Although the cause is unknown, it's suggesting that disordered immunity with both antibody and cell-mediated tissue damage occurs. The disease affects patients of any age. Characteristic clinical manifestations are diverse but in clude saddle nose deformity, sinusitis, productive coughing, myalgia, fever etc. Characteristic laboratory abnormalities include elevated ESR, neutrophilic leukocytosis, anemia and positive test for ANCA test. Renal biopsy is important for diagnosis. The treatment of choice is a combination of corticosteroid and cytotoxic agent. A53-year-old woman was admitted to our hospital because of productive coughing, short of breathing, oliguria, nausea, and vomiting. Three months ago, she was suffered from general weakness, poor appetite, tingling sensation on extremity, and loosely stool. Twenty days ago, above symptoms were aggravated, she admitted local clinic. Six days ago, because of CBC showed anemia , she was done transfusion. During transfusion, she was developed urticaha then productive coughing, dyspnea, increased serum BUN and creatinine levels. She was transferred to our hospital under the impression of ARF. On the admission, she was chronic ill-looking appearance with pale conjunctiva, tachypnea, dyspnea, and cold sweating. We have checked the patient by CBC, serum and serologic test, X-ray, ANCA test, renal biopsy. With renal biopsy microscopic examination study revealed necrotizing vasculitis, We treated a combination therapy with methyl-PDS and cyclophosphamide. She had a good response. So we report wegener's granulomatosis with the review of relevant literature.

Objectives: The purpose of this study was to assess the correlation relationship between personal exposure and urinary hippuric acid in biological monitoring for airborne toluene in an industrial complex and in general environments. Methods: Personal exposure to toluene and its metabolite, hippuric acid, in urine were simultaneously measured in occupational environments area near an industrial complex and in general environments. The study subjects were divided into three types: 137 workers who use organic solvents in the workplace, 210 residents living near a dyeing industrial complex, and 379 residents living in general environments. The toluene exposures of workers and residents were measured by a passive sampler for four days. The urine of participants was sampled when the passive samplers of personal exposure were collected. Results: The toluene and hippuric acid concentrations of workers were the highest, followed by the concentrations of residents living near a dyeing industrial complex and residents living in general environments. The coefficient of correlation between the concentrations of toluene and hippuric acid among workers was 0.749 (p<0.01) in the workplace. On the contrary, correlations between the concentrations of toluene and hippuric acid among residents living near a dyeing industrial complex and residents living in general environments were all not significant. The relationship between the concentrations of hippuric acid and toluene in three types could be described by the exponential growth model. Conclusions: This study analyzed the relationships between toluene exposure and the concentrations of hippuric acid in urine in high, middle, and low exposure environments, and could be described by the exponential growth model.

Hyeon-Jeong Kim(김현정),Dong-Hee Kim(김동희),Jin-Young Lee(이진영),Jae-Sam Hwang(황재삼),Joon-Ha Lee(이준하),Seul-Gi Lee(이슬기),Hyeon-Guk Jeong(정현국),Bong-Jeun An(안봉전) 한국생명과학회 2013 생명과학회지 Vol.23 No.1

CopA3를 이용하여 피부 염증에 대하여 연구를 하였다. 산화질소와 cytokine의 생산은 면역세포의 대표적인 염증인자이다. 세포는 LPS 처리 후 한 시간 뒤에 CopA3를 처리하였다. 세포 독성이 나타나지 않는 농도인 5, 25, 50, 100 ㎍/㎖를 사용하였다. CopA3는 NO, TNF-α, IL-1β, IL-6, iNOS, COX-2의 생성을 저해 시켰다. iNOS와 COX-2 역시 100 ㎍/㎖의 농도에서 각각 54%, 65%가 저해가 되었다. 게다가 CopA3는 염증성 사이토 카인인 TNF-α, IL-1β, IL-6의 생성을 감소 시켰다. 이러한 결과로 CopA3는 염증 예방과 치료에 효과적임을 확인 할 수 있었다. The objective of this study was to evaluate the effect of the synthetic CopA3 peptide of Copris tripartituson skin inflammation. Regulatory mechanisms of cytokines and nitric oxide (NO) are involved in the immunological activity of RAW 264.7 cells. Tested cells were treated with different concentrations of CopA3 and further cultured for an appropriate time after lipopolyssacharide (LPS) addition. During the entire experimental period, 5, 25, 50, and 100 ㎍/㎖ of CopA3 had no cytotoxicity. At these concentrations, CopA3 inhibited tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). CopA3 also inhibited the expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2). CopA3 inhibited the activity of iNOS and COX-2 by 41% and 59%, respectively, at 100 ㎍/㎖. In addition, CopA3 reduced the release of inflammatory cytokines including TNF-α, IL-1β, and IL-6. These results suggest that CopA3 may have significant effects on inflammatory factors and that it may be a potential anti-inflammatory therapeutic agent.

Objectives : The aim of this study was to investigate the relationship between stress type and Ryodoraku score (RS) in patients with functional dyspepsia. Methods : 92 (30 male, 62 female) patients with functional dyspepsia were included in this study. Degree of stress was evaluated by GARS and BEPSI scale which can assess acute and chronic stress, respectively. RS of the patients was measured, and mean, sum of gaps and standard deviation (SD) in their RS were taken. First, patients were divided into two groups by sex, and by mean RS $40{\mu}A$ (above and below). GARS and BEPSI scale of each group was compared. Second, correlation between stress scales (GARS and BEPSI) and variation indexes of RS (sum of gaps and SD) was examined. Result : 1. The mean RS is higher in male patients than in female ones. 2. No significant difference was noted in GARS and BEPSI scale associated with above end below the mean $40{\mu}A$ RS. 3. The sum of gaps and SD of RS has significant correlation with GARS scale but not with BEPSI scale. Conclusions : These results suggest that the sum of gaps and SD of RS are associated with acute stress in patients with functional dyspepsia. Thus, it is thought that RS can be useful in assessing acute stress in patients with functional dyspepsia.

기존의 로봇의 전역 성능 평가방법의 단점과 한계를 극복하고자 주어진 운동 경로 및 작업 공간을 평가하기 위한 방법을 제안하였다. 평가 구간 내 평가 지표의 최소값, 평균값 그리고 표준편차를 이용한 방법으로 기존의 다양한 평가 지표에 적용 가능할 것으로 기대한다. 보유중인 연구용 로봇 팔에 토크-힘 전달 효율을 나타내는 Inertia Matching Index와 Condition number를 혼합한 변형 지표를 제안한 성능 평가 방법에 적용하였고 이를 이용하여 주어진 작업에 대한 설계 변수 최적화를 수행하였다. 기존 모델과 최적화 수행 후 모델의 힘과 토크의 비, 소모 토크 그리고 말단 장치에서의 힘을 비교하여 제안한 전역 성능 평가법의 사용 가능성을 검증하였다. For the improvement of existing evaluation method about the global performance of the robot, we propose an evaluation method along the trajectory or work space. This method, using a minimum, an average, and a standard deviation in the evaluation space is expected to apply any existing performance index. We propose a modified index, combining the Inertia Matching Index and the Condition Number and then apply it to evaluation method we proposed Parametric design optimization of a 7-DOF manipulator was conducted using a modified index and a proposed evaluation method. Then, the usefulness of the proposed evaluation method was verified through a comparison between an original model and an optimal model about three aspects; Force-torque ratio, consumed torque, and force of the end-effector.
