The steel slag, a by~product which is produced during the manufacture of steel by refining pig iron, is mainly used as road materials after aging it. It is necessary to age steel slag for long time in air because the reaction with water and free-CaO in steel slag could make the expansion of volume. This problem prevents steel slag from being used as aggregate for concrete. However, steel slag used in this study was controled by a air-jet method which rapidly cools substance melted at a high temperature. The rapid-chilling method prevents from generation of free-CaO in steel slag. The rapid-chilled steel slag is similar to be spherical shape and has the heavier specific gravity than natural aggregate. Therefore, it could be used to manufacture radiation shielding concrete as fine aggregate. This paper investigated the engineering properties of radiation shielding concrete when using rapid-chilled steel slag as fine aggregate. As results of this study, the increase of use of rapid-chilled steel slag decreased the desirable water content of concrete but developed the rate of radiation shielding of concrete. The strength of concrete using it is similar to that of concrete using river sand.

The more the life environment, eastern idea, culture, factory automation system, and information technology complicates, the more the various human error brings about. It brings about all kind of accidents and occupational diseases. Also the death and sickness or injury by psychological stress among the human error has increased every year. Therefore this paper describes the Korean life change unit model through statistical testing with the proposed life change unit factors on the married workers living the middle area. The proposed model can be simply used in order to minimize the industrial accident and human error in real fields. Finally, the result will be helpful for the better safety management.

진행된 HIV 감염 환자에서 십이지장의 미란성 병변으로 발현한 Mycobacterium genavense 감염 1예

진상만,박종선,김홍빈,오명돈,최강원,김희연,국윤호,김남중 대한감염학회 2007 감염과 화학요법 Vol.39 No.4

Mycobacterium genauense는 최근에 알려진 미코박테륨으로서, 식욕 부진, 체중 감소, 설사, 림프절 병증 등 파종성 Myocobacterium avium-intracellulare complex 감염과 유사한 임상상을 보이며, 위장관 침범을 잘 하는 것으로 알려져 있으나 아직 국내에서 증례는 보고된 바가 없다. 저자들은 진행된 HIV 감염 환자에서 십이지장의 미란성 병변으로 발현한 Mycobacterium genavense 감염 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. 환자는 상복부 동통과 발열, 설사로 내원하였다. 십이지장의 미란성 병변에서 시행한 조직검사에서 항산균이 가득 차있는 거품세포가 관찰되었으며, 이 검체에서 16S rRNA 유전자의 중합연쇄반응 검사를 시행하여 Mycobacterium genavense를 확인하였다. Mycobacterium genavense, first identified in 1990, is known as a pathogen that mimics disseminated Myocobacterium avium-intracellulare complex (MAC) infection with particular propensity for the gastrointestinal tract. In Korea, no case with the organism has been reported. Herein we report a case of Mycobacterium genavense infection that manifested with erosive lesion of duodenum in a patient with acquired immune deficiency syndrome. The patient presented with epigastric pain and fever, diarrhea. Duodenal biopsy showed histiocytic infiltration with numerous acid-fast bacilli. Identification of the mycobacterial isolate by the polymerase chain reaction restriction analysis of 16S rRNA gene revealed Mycobacterium genavense.

김진만,강대영 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.1

Chloroform, a known hepatotoxic agent, is mainly metabolized in liver, and its hepatotoxic action is influenced by the administration of phenobarbital, chlorinated insecticides,etc. To study the effects of phenobarbital treatment upon the acute hepatic lesion induced by chloroform, male Sprague-Dawley rats were pretreated with phenobarbital (80mg/kg) for 3 days intraperitoneally. After 24 hours, chloroform (0.2ml/kg) was injected intraperitoneally and sacrified. Control animals were treated with saline, phenobarbital and chloroform respectively. Each group measures S-GOT and S-GPT after 24 hours of last treatment. The histopathological findings and level of hepatic enzymes of the control and experimental groups were as follows : 1. In the phenobarbital and chloroform treated group, the enzyme levels of S-GOT and S-GPT were 20 to 30 times higher than those of the control group. 2. The main histopathological changes of the chloroform treated group were centrilobular hydropic degeneration and necrosis. 3. The degree of centrilobular necrosis in the phenobarbital and chloroform treated group was more severe than that of the chloroform treated group.

The authors retrospectively reviewed extranodal malignant lymphomas which include various distinctive clinicopathologic entities according to the new WHO lymphoma classification system. The aim of this study was to analyze the clinical characteristics of extranodal lymphomas and the relative frequency of the subtypes with immunophenotype in the Daejeon city and Chungcheong province. The authors reviewed 134 cases of extranodal lymphoma out of 220 cases of total non-Hodgkin's lymphoma which was diagnosed during the last 10 years. Among the cases, gastric lymphomas (26.1%) were the most common anatomic site. Nasal and paranasal (14.4%), skin (13.4%), and Waldeyer's tonsillar ring (11.2%) lymphomas were relatively common in order of frequency. The most frequent subtypes of extranodal lymphoma were marginal zone B-cell lymphoma of MALT (31%), diffuse large B-cell lymphoma (20%), peripheral T-cell lymphoma, unspecified (15.7%), and nasal NK/T cell lymphoma (13.4%), in decreasing order. Compared with a previous studies, the relative frequency of nasal NK/T cell lymphoma was much higher in our study than western countries and similiar to East Asia. The immunophenotype of our extranodal lymphomas was mainly B-cell type (68%) and the remaining cases were T- or NK-cell origin. In conclusion, the occurrence rates for various subtypes of extranodal lymphoma in Daejeon and Chungcheong province were distinct from those in western countries and similiar to those in East Asian countries. The most distincitive entities in our study were marginal zone B-cell lymphoma of MALT and nasal NK/T cell lymphoma. It also appears that the frequency of lymphoma subtypes is changing according to the classification system.

Because elderly individuals are participitating in social work as adult inspite of their physical handicapes such as hearing difficulty, visual difficulty and limit of motion, they are continually exposed to the risk of injury. Trauma is now fifth cause of death in elderly of over 65 years old, and the elderly suffer disproportionately high injury-related motality comparing with younger adults. In addition, sometimes elderly patients don`t complaint of pain on injured site because of high threshold to pain. We studied about occurence of neglected injury due to high threshold to pain in geriatric trauma patients. When we diagnosised injury that patients did not complaint of pain on injured site through physical examination and radiologic examination, we defined that as neglected injury. There were 8 (8%) geriatric patients who didn`t complaint of pain on injured site on admission to emergency center, but only 0.7% of adult patients had neglected injury. The severity was estimated by use of AIS(Abbreviated Injury Scale), and the severity of all neglected injuries were above AIS 2 point. The neglected injury were head injuries(4 in number), abdominal injury(1), pelvic injuries(2) and extremity injury(1). So if geriatric trauma patients were admitted to emergency center, we recommand full physical and radiological examinations although patients don`t complaint of pain.

Plastic surgeons who frequently deal with trauma and deformity of the eyelids and orbits, need have an abundant knowledge of the accurate anatomical morphology and acceptable proportion of them. The normal value of the anatomical morphology and function of the eyelid has not yet been standardized in Korea. The authors measured anthropometry of normal Korean eyelids and statistically analysed in 2,151 individuals including 1,078 male and 1,073 female. Statistical analysis of these measurements offers valuable information about the chronological growth, size, and shape of healthy Korean eyelids. The results are as follows : 1. There was no significant statistical difference between the right and left sides in all measurements. 2. The growth of the eyelid reached the adult level at about 20 years of age and then the growth can be divided into 3 patterns, the first one slowly increased, the seconded one was a stationary, and the last one slowly decreased. 3. The following statistics were recorded for males and females. The cornea-lateral canthal distance was 7.9mm and 7.3mm, the diameter of the cornea was 13.8mm and 13.6mm cornea-medial canthal distance was 7.8mm and 7.5mm the horizontal dimension of the palpebral fissure was 29.7mm and 28.4mm, the vertical dimension of the palperbral fissure was 7.9mm and 8.0mm, the slant of the palperbral fissure was 9.5 degrees an 10.6 degrees, the intercanthal distance was 36.5mm and 37.2mm, the width of the glabella was 24.4mm,. and 24.1mm, the interpupillary distance was 66.1mm and 63.9mm, the ectocanthion-superior margin of the palpebral fissure distance was 14.9mm and 14.2mm, the endocanthion-superior margin of the palpebral fissure distance was 14.9mm and 14.2mm, the height of the opened upper eyelid was 10.3mm and 10.0mm, the height of the closed upper eyelid was 18.2mm and 18.1mm, levator function by the Berke's method was 16.2mm and 15.6mm, MLD was 7.2mm and 7.1mm, and MRD1, was 2.7mm and 2.6mm respectively. 4. The vertical dimension of the palpebral fissure, slant of the palpebral fissure, and height of the double eyelid fold were greater in females than males. The intercanthal distance and width of the glabella was nearly the same in males and females and other measurements were greater in males than females. 5. A double eyelid fold was seen in about 36% of males and 50% of females. The average height of the double eyelid fold with the eye closed in 20 year old females was 5.2mm and 30 to 50 year old females was 5.5mm. The most frequent shape of the double eyelid fold was type 5. 6. The epicanthus was present in 58.1% in this series and existed in over 90% under age 10, but disappeared in about 90% of the people over 50. The most frequent shape of the epicanthus was tarsalis type.

일부 산모에서 산모혈, 제대혈, 모유 및 태반에서의 환경 에스토레겐성 화합물(PCBs) : Environmental estromgen compounds(PCBs) in Maternal Blood, Cord Blood, Human Milk and Placenta of Korea women

이강숙,임현우,노영만,구정완,조재천,박정일,김진홍 가톨릭대학산업의학센타 산업의학연구소 2003 韓國의 産業醫學 Vol.42 No.2

The production and intensive use of organochlorine chemicals, both in agriculture and industry, have led to wide spread contamination of the environment. There may be biological effects of organochlorine contaminated breast milk even when levels are below those concentrations that are currently regarded as tolerable. To evaluate the exposure of to fetus PCBs, we measured the sum of 13 congeners of PCBs in maternal blood, cord blood, breast milk and placenta of 30 Korean women by gas chromatograpy/electron capture detector. The concentration of total PCBs of maternal blood, cord blood and breast milk were 7.16±4.29 ㎍/ℓ, 5.16±3.12 ㎍/ℓ, 1.77±2.87 ㎍/ℓ respectively and they have no significant correlation. PCBs in placenta was not defected. However there were no significant differences of PCBs according to age, education, body mass index, parity, breastfeeding, smoking and drinking.

박성균,이강숙,노영만,구정완,민선영,한진구,고원경,김미란,정재근,이종승,김진홍 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.1

목적 : 본 연구는 지방조직과 혈청의 PCBs와 DDE 농도를 측정하고, 이에 영향을 미치는 것으로 알려진 요인들과의 관련성을 평가하고자 하였다. 방법 : 유방암, 자궁내막증 등 유기염소계 화합물의 영향이 있는 것으로 알려진 호르몬 관련 질병을 제외한 부인과 환자 52명을 대상으로 지방조직과 혈청을 분석하였으며, 설문조사를 통하여 연령, 교육수준, 직업, 비만도, 흡연과 음주, 출산력, 수유력등을 조사하였다. 지방조직과 혈청의 PCBs와 DDE 농도는 가스크로마토그래피를 사용하여 측정하였다. 결과 : 지방조직의 경우, 13개 PCBs congeners 농도의 합은 중앙값이 48.29 ng/g, 기하평균값이 56.78 ng/g이었고, DDE 농도는 중앙값이 142.89ng/g, 기하평균값이 117.06 ng/g이었으며, 혈청의 경우는 PCBs congeners 농도의 합은 중앙값이 4.67 ㎍/L, 기하평균값이 4.85 ㎍/L이었고, DDE 농도는 중앙값이 1.75 ㎍/L, 기하평균값이 2.09 ㎍/L로 나타났다. 지방조직과 혈청의 DDE 농도 사이는 높은 상관성을 보였으나(r²=0.310, p=0,0002), PCBs는 상관성이 약한 것으로 나타났다(r²=0.029, p=0.2582). 영향요인을 범주화한 후 로그변환 시킨 지방조직과 혈청의 PCBs, DDE 평균의 차이를 분석한 결과, 지방조직의 DDE만이 출산자녀수(p=0.015), 초산연령 (p=0.014), 비만지수(p=0.035)와 연관성이 발견되었다 다중회귀분석의 결과 지방조직의 DDE는 출산자녀수가 적을수록, 초산연령이 늦을수록 증가하는 경향을 보였다. 결론 : 출산자녀수와 초산연령, 비만도가 지방조직의 DDE와 관련성을 보였으며, 또한 유기염소계 화합물의 장기간의 노출에 의한 영향을 평가하는데 있어서 혈청보다 지방조직이 더 유용한 생물지표임을 알 수 있었다. Objectives : This study was purposed to determine the levels of PCBs and DDE in adipose tissue and serum and to evaluate the relations with factors affecting these levels. Methods : We analyzed adipose tissues and sera from 52 gynecologic benign disease patients aged 27-78 years, except hormonal diseases such as breast cancer and endometriosis. We also surveyed age, education, occupation, body mass index (BMI), smoking, drinking, number of children, and duration of breastfeeding by questionnaires. Tissue and serum levels of PCBs and DDE were measured using gas chromatography. Results : The median and geometric mean levels of PCBs were 48.29 ng/g, 56.78 ng/g for adipose tissue and 4.67 ㎍/L, 4.85 ㎍/L for serum, and those of DDE were 142.89 ng/g, 117.06 ng/g for adipose tissue and 1.75 ㎍/L, 2.09 ㎍/L for serum, respectively. Adipose tissue and serum levels for DDE showed high correlation (r²=0.310, p=0.0002), but those of PCBs didn't (r²=0.029, p=0.2582). In analyses of the differences of the means of log transformed adipose tissue and serum PCBs and DDE levels for groups of potential covariates, only adipose tissue DDE levels were significantly associated with number of children (p=0.015), age at first birth (p=0.074) and BMI (p=0.035). In multiple regression analysis, adipose tissue DDE levels were significantly increased with decreasing number of children and increasing age at first birth. Conclusions : This study suggested that parity and adiposity were associated with levels of DDE in adipose tissue, and adipose tissue is a better biomarker than serum for evaluating the long-term exposure of organochlorines.
