The skin is an uncommon site of distant metastasis from any internal malignancy, and the incidence of metastatic skin lesions as the first symptom of disease is only 0.8% in patients with all systemic malignancies. Furthermore, cutaneous metastasis from adenocarcinoma of the stomach has been found to be extremely rare. A 35-year-old female patient was admitted due to multiple cutaneous nodules in her chest, abdomen, and back. A gastroendoscopic examination and biopsy was made according to the results of skin pathologic findings. Stomach and skin biopsy results revealed a signet ring cell type of adenocarcinoma. A case of gastric adenocarcinoma in which metastatic skin nodules appeared as the first sign of disease, is here in reported with a review of related literature.

This paper presents experimental and analytical studies of ultimate strength of [30_2/-30_2/90]_s carbon/epoxy laminates with free-edge delamination under uniaxial tension. We performed tensile test for laminates with Telflon inserted on interfaces to simulate initial free-edge delamination. The experiment reveals that extensional stiffness of the laminate decreases by the initiation of the delamination, and that strength of the laminate without delamination is smaller than that of the laminated with delamination. Generalized quasi-three dimentional finite element analysis, which employs energy release rate and maximum stress criteria, predicts the ultimate strength of the laminates with sufficient accuracy.

大邱-倭館 以北의 霞山洞層에 나타나는 赤色層 分布에 關하여

梁承榮 경북대학교 교육대학원 1972 논문집 Vol.3 No.-

This study deals with the distribution of Reddish beds of Hasandong Formation in the northern part of Daegu-Waegwan area. The numbers of Reddish beds are counted more than 100 at northern most part of the study area while only 10 at southern area of the middle part. Near the Mt. Palgong, Reddish beds are disappeared, but they appear again at south-east of Waegwan area. It seems that the Reddish beds cannot be interpreted as an indicator of the paleoclimate such as subtropical savanna. The geological boundaries, which were drawn according to intercalation of the Reddish beds,are never related to isochronous horizon. It seems that the disappearance of Reddish beds near the Mt.Palgong is partly due to the result of the intrusion of granite by which this area was affected thermal metamorphism. According to Rock Color Chart (published by G.S.A. 1963), the colors of 60 samples of Reddish beds are generally confined in 3 colors; grayish red(5R 4/2), grayish red (10R 4/2) and moderate red(5R 5/4). The microscopic examination shows that the most sandstones associated with the Reddish beds are classified as arkose according to Dapples' scheme(1953).

5년간 특수건강진단기관 분석정도관리 결과 분석

강성규,양정선,이미영,박인정,정호근 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.1

목 적 : 1980년대 후반부터 산업보건에서 혈중 및 요중 중금속농도 분석의 정확성 문제가 크게 부각되었다. 같은 시료를 가지고 분석기관마다 보이는 커다란 오차로 인해 직업병 진단 결과에 대한 신뢰성을 크게 감소시켰다. 이에, 노동부에서는 1992년부터 특수건강진단 기관에 대한 생체시료 분석정도관리 프로그램을 시작하였다. 본 연구는 1995년부터 시작된 생체시료 분석정도관리 5년간의 결과를 보고하고, 현재 생물학적모니터링으로 사용되는 항목과 빈도를 조사하고 이 항목의 정도관리 참여율을 비교하여 산업보건 관계 연구나 직업병 관리에 참고할 수 있도록 하기 위해 실시하였다. 방 법 : 생체시료 분석정도관리는 무기와 유기분석분야로 나누어 일년에 전후반기 2회 실시하고 있으며, 지정항목과 자율항목으로 구분하고 있다. 지정항목인 혈중 납과 요중 마뇨산은 분야별로 한 번에 3개 농도수준을 주어 2개 이상이 기준값의 ±15%내외의 범위에 들면 적합한 것으로 판정하고 있으며, 자율항목은 2개의 시료를 주어 2개 모두 기준실험실 평균값의 ±3SD 내외의 범위에 들면 적합한 것으로 판정하고 있다. 결 과 : 지정항목인 혈중 납과 요중 마뇨산 분석은 평균 적합률이 각각 89%, 90% 이었고, 대학기관, 비영리법인, 종합병원, 사업장 자체기관별로 차이는 없었으나 신규 기판의 적합률 70% 수준으로 상대적으로 낮았다. 자율항목의 적합률은 평균 50% 수준이었고, 저농도보다는 고농도의 적합률이 떨어졌다. 국내에서 가장 많이 분석되고 있는 항목은 요중 마뇨산과 혈중 납이었고, 혈중 및 요중 망간도 많이 분석되고 있었다. 요중 삼염화물, 페놀, 만델산, 카드윰, 메칠마뇨산, 크롬 등도 많이 분석되고 있는 항목이었다. 혈중 망간, 요중 수은, 요중 NMF는 정도관리에서 적합판정을 받은 기관의 숫자보다 실제 분석을 하고 있는 기관의 숫자가 많았다. 결 론 : 지난 5년간의 생체시료 분석정도관리 결과 우리나라 분석실험실의 분석능력은 향상되고 있으나, 자율항목에 대한 분석능력은 아직 미흡한 것으로 나타났다. 그리고, 아직 일부 일부 항목에 대해서는 외부 정도관리 없이 분석되고 있는 경우도 있었다. Objective : The accuracy of analytical results of blood and urine heavy metals came out to the main issue on occupational health from late eighties. The discrepancy of the results for same samples from different laboratories made the diagnosis for occupational diseases be unreliable. Therefore, a quality control program for analysis of samples taken from workplace had been introduced in Korea since 1992. This study aims to show the quality control program for analysis of blood and urine samples and its proficient rates from 1992 to 1999 and to know how they have been being used in occupational health. Methods The quality control program runs twice a year with mandatory items of blood lead and urine hippuric acid and voluntary items of blood cadmium and manganese and urine mandellic acid and methyl hippuric acid. Participant laboratories are receiving three levels for each items and two out of three samples have to be qualified for being a profi-cient laboratory for the item. The acceptable range of blood lead and urine hippuric acid is ± 15% and that of the others is within 3 SD (standard deviation) from the reference values. Results : The proficient rates of blood lead and urine hippuric acid was 89%, 90%, repectively, however those of the other voluntary items have been from 51% to 62%. The proficient rates of urine mercury and urine N-methylformamide (NMF), which are introduced since 1999, were very poor. Urine hippuric acid and blood lead were analyzed frequently for the purpose of biological monitoring conducting by special health examination organizations. Urine and blood manganese and urine metabolites of trichloroethylene, urine phenol, methylhippuric acid and cadmium were followed. Conclusions : In conclusion, the quality control program for biological monitoring has dramatically improve the ability of analysing blood and urine samples and eventually con-tributes to diagnose occupational diseases and to prevent occupational poisoning. However, some biological monitoring data, such as urine manganese, mercury and NMF, have been still reported from laboratories that were not accepted as a proficient laboratory.

VOCs (Volatile Organic Compounds) have been produced commercially and used for many purposes in the chemical industry including the manufacture of herbicides, plastics, and solvent. Their emissions affect the change of climate, the growth and decay of plants, and the health of human beings and animals. Therefore it is necessary to limit and control of VOC emission. There are various removal technologies of VOCs, such as catalystic oxidation, biofiltration, Adsorption, Thermal oxidation and Menbrane separation. In this study, we examined both source and components of odor and VOC pollutants emitted from Jeonju and Iksan industrial Area. According to the results, the main VOCs used in the two industrial Area were benzene, toluene, chloroform, methanol, methylene chloride, xylene, ethyl ethyl ketone etc. Especially, hydrogen peroxide and methanol were extremely used in these complex. The regulation of VOC will be more strict within near future. Therefore, this research work will be applicable removal efficiency of VOC emitted from Jeonju and Iksan industrial Area as a fundamental data.

본 연구는 농촌지역 정신과 환자들의 의료서비스 이용 형태를 알아보고자 하여 행하여졌다. 경기도 연천군 주민중 1993년 1년간 지역 의료보험과 의료보호자료에서 정신과적 진단을 받은 사람들 1295명 중 209명을 대상으로 하였다. 연구자들이 제작한 반구조화된 면담도구를 사용하여 13명의 훈련된 면담자에 의해 증상을 처음 느낀 후 이용한 의료서비스를 차례대로 조사하였다. 결과는 다음과 같다. 정신증적 장애 환자들은 정신과 치료만을 받은 경우가 28.8%이며 처음 방문한 의료서비스는 정신과 45%, 일반의 28%, 약국 6%, 한방치료 5%, 요양원 6%, 기타 10%였다. 비정신증적 장애 환자들은 정신과를 한번이라도 이용한 경우는 32.1%였고 처음 방문한 의료서비스는 정신과 15%, 일반의59%,약국 17%, 한방치료8%, 기타1%였다. 진단에 따라서는, 정신분열병의 경우 64.5%가 처음에 정신과를 방문하였고 정동형 정신병의 경우는 20.8%에 불과했고 64.1%가 일반이나 약국을 처음에 방문하였다. 신경증적 장애(ICD-9 300)는 40.0%가 일반의만을 방문했다. 이상의 결과로 정신분열병 환자들은 대다수가 정신과 치료를 받는 것으로 나타났으나 정동형 정신병과 신경증적 장애는 다수가 일반의를 이용하는 것으로 나타났다. 지역사회 정신보건에서 일반의의 역할이 매우 중요하며 일반의에 대한 정신과 교육이 절실하고, 보다 전문적인 치료환경과 기술을 요하는 경우에는 정신과와의 연계 체계의 필요성도 요구된다. The purpose of this study was to investigate the pathways of health care seeking by the psychiatric patients at a well - defined rural area in Korea. Among 1,295 patients diagnosed to have mental disorders by ICD-9 in a year, all the psychotic patients(184 in number) and randomly selected 15% of nonpsychotic patients(162 in number) were selected as subjects of this study. Thirteen well - trained interviewers collected the data using semi-structurd inter-view instrument developed by the authors. Two hundred nine patients(60.4%) fully responded to the interviews. As for psychotic patients, 28.8% used only psychiatric services, and the first visits for help were psychiatrists, general practitioners, pharmacists, asylums and oriental herb medicine in the order of decreasing frequency. Only 32.1% of nonpsychotic patients used mental health specialties during the course of their illness, and their most common first visits for care were general practitioners(59%) followed by pharmacists(17%) and psychiatrists(15%). Majority(64%) of schizophrenic patient visited psychiatrist first, while 64.1% of affective psychosis patients visited general practitioners and pharmacists first. The forty percent of neurotic patients(ICD-9 300) visited general practitioners only for their health care.
