원종욱,하국환,송재석,노재훈,김형렬,이대희,이강희 大韓産業醫學會 2003 대한직업환경의학회지 Vol.15 No.1

목적: 본 연구는 뇌·심혈관질환으로 요양 신청한 근로자들에게서 업무상 질병 인정 여부에 영향을 주는 요인을 파악하고, 이들의 특성을 분석하여 뇌·심혈관질환 예방에 도움을 주고자 한다. 방법: 1998년과 1999년 경인지역 3개 근로복지공단에 뇌·심혈관질환으로 요양신청한 386명 가운데 분석 가능한 369명을 연구대상으로 하였다. 재해조사 복명서를 기초로 하여, 일반적특성, 재해 관련 특성 및 과거병력을 조사하였으며, 업무상 질병 인정여부에 영향을 주는 요인을 알아보기 위하여 로지스틱 회귀분석을 실시하였다. 생존자 96명중 전화 면접 조사가 가능했던 72명을 대상으로 직무 스트레스관련 요인을 조사하였다. 직무 스트레스는 업무요구도, 지적 결정권 및 개인적 시간의 자유도로 나누어 조사하였다. 결과: 369명 가운데 167명이 업무상 질병으로 인정받았으며, 인정 여부와 무관하게 연구대상자 가운데 62%가 한가지 이상의 뇌·심혈관계 질환의 위험요인인 질병을 갖고 있었다. 특히 고혈압은 전체 연구대상자의 53.9%에게 존재하였다. 인정 여부를 종속변수로 한 로지스틱 회구분석 결과 사망하여 요양 신청한 경우가 생존한 경우보다 요양 승인의 비차비가 26.5로 요양이 승인될 가능성이 높았다. 작업조건의 변화가 있는 경우는 6.5배, 작업장에서 발생한 경우는 4.9배, 여자는 남자보다 4배, 야간 작업이 있었던 경우는 2.9배, 근무시간 중 발생한 경우 2.5배 그리고 과거력상 뇌·심혈관계 질환 관련 병력이 없는 경우는 그렇지 않은 경우보다 1.8배 더 많은 요양 승인을 받았다. 전화 면접을 통한 직무스트레스를 조사한 결과 개인적 시간의 자유도가 낮을수록 업무상질병 인정을 더 많이 받았지만, 로지스틱 회귀 분석 결과 직무 스트레스는 업무상 질병 인정에 아무런 영향을 주지 못했다. 결론: 뇌·심혈관질환을 예방하기 위해서는 위험요인 가운데 가장 많은 비중을 차지하고 있는 고혈압을 관리하는 것이 필요하고, 업무상 질병 여부를 판단하는데 있어 보다 객관성을 유지하기 위해서는 과로나 스트레스에 좀더 큰 비중을 두어야 한다. Objectives: This study was performed to analyze the factors that affect the decision to approve workers compensation claims for cerebrovascular and cardiovascular diseases and to analyze the worker characteristics. Methods: Three hundred, sixty-nine cases were collected based on the workers compensation records of three Seoul and Incheon Regional centers of the Labor Welfare Corporation between 1998 and 1999. They contained the general characteristics, injury information and past medical histories. The x2-test and logistic regression were performed to investigate the factors affecting the approvals. Seventy-two survivors were surveyed by telephone for job stress. Job stress was surveyed in three parts: job demands, decision latitude and personal free time. Results: Of the cases, 167 obtained approval from the Corporation; the others did not. Regardless of approval, 62% of all subjects had more than one of the cerebral and cardiovascular risk factors. Especially, 53.9% of subjects had hypertension. Accordings to the logistic regression, the fatal cases had a higher approval rate (OR=26.4, CI=9.13-76.22). The cases with working condition change (OR=6.5, CI=3.45-12.07), accidents on worksite (OR=4.9, CI=2.39-10.07), female (OR=4.0, CI=1.21-13.3), accidents at night duty (OR=2.9, CI=.156-5.39), cases occurring on duty (OR=.25, CI=1.34-4.72) and cases without past diseases history (OR=1.8, CI=1.02-3.36) also had higher approval rates. Telephone survey found that the approval rate increased with decreasing freedom of personal time schedule. However, the logistic regression revealed that job stress didnt affect the approvals. Conclusion: To prevent cerebrovascular and cardiovascular diseases, the most important aspect is to control hypertension which is the most common risk factor among the victims. Moreover, job stress and over working should be considered in the just approval of the workers compensation claims.

원종욱,노재훈,김춘성,박윤정,김치년 大韓産業醫學會 1996 대한직업환경의학회지 Vol.8 No.1

Direct Black 38, a kind of benzidine-based azo dye, is widely used as a dye for fabric, leather, cotton, cellulosic material, paper, wool, silk, and so on. Benzidine-based azo dyes are proven as a mutagen and linked to bladder cancer. In 1978, National Institute for Occupational safety and Health recommended that three widely used benzidine-based dyes(Direct Black 38, Direct Blue 6, and Direct Brown 95) should be treated as carcinogens. In this experiment, metabolism of the benzidine-based dye, Direct Black 38 was examined by using an isolated liver perfusion system. To measure the metbolites of Direct Black 38, 8.0μM, 30.5μM and 63,3μM of Direct Black 38 was added into the recirculating perfusate of the isolated perfused rat liver. Samples were collected at 0, 10, 20, 30, 60, 90, 120 minute. They were treated with sep-pak and methanol, and the metabolites were detected and quantified with high performance liquid chromatography(HPLC). Residual non-reactive dye in the perfusate and liver was reduced to benezidine and then analyzed by HPLC. Detected metabolites of Direct Black 38 were benzidine, N-acetybenzidine, and N,N'-diacetylbenzidine. The average concentration of benzidine was 0.1μM and this concentration was maintained throughout the experimental period. The average concentration of Nacetylbenzidine was 0.22μM and took the same pattern of benzidine. When 30.5μM of Direct Black 38 was added to the perfusate, only N,N'-diacetylbenzidine increased slightly with time. From the above results we suggest that only small amount of Dirst Black 38 might be metabolized to benzidine regardless of the s, amount of the Direct Black 38. There are some possible explanations. The liver was damaged during the perparation. And the function of the perfused liver decreased rapidly because adsorbing of dye. The benzidine, acetybezidine and diacetylbenzidine metabolized to other metabolites were not detected in this experiment.

Object : This study was performed to increase the sensitivity and specificity for screening the examinee of second hearing test. Methods : Study subjects were 219 workers who exposed more than average 80dB. They were taken the hearing test two times, before noose exposure and at 1 hour to 4 hours after worksite noise exposure. To investigate the ambient noise workers who were taken the hearing test in the test room which ambient noise was less than 45dB were classified Group I and the others were classified Group II . To calculate the sensitivity and specificity we made it gold standard whether worker had noise induced hearing loss. Results : Difference of hearing loss between before and after noise exposure for left and right ear was 11.4 dB and 11.7 dB respectively at 500 Hz, 8.7 dB and 9.6 dB at 1,000 Hz, 6.3 dB and 6.9 dB at 2,000 Hz and 6.9 dB and 7.4 dB at 4,000 Hz In Group I. That for left ear and right ear was 5.8 dB and 4.9 dB at 500 Hz respectively, 5.4 dB and 6.4 dB at 1,000 Hz, 6.3 dB and 5.3 dB at 2,000 Hz, and 5.5 dB and 5.8 dB at 4,000 Hz in Group II. The sensitivity was 100 in both Groups and the specificity was increased to 58.3 and 71.8 in Group I and Group II respectively until 10 dB was deducted from hearing level at 1,000 Hz and 4,000 Hz. Conclusion : When the screening hearing test was performed at worksite, we might deduct 10 dB from measured hearing level to increase the specificity without reduction of sensitivity.

최재원,김진규,김종욱,안주현 한국공업화학회 2004 응용화학 Vol.8 No.2

Ionic liquids have being investigated for many applications including reaction solvent, separation medium, and electrolytes of supercapacitor and solar cell. Since ionic liquids are liquids which are entirely composed of ions, they can have high ionic conductivity. They are also non-volatile and non-flammable, and exist as liquid state over a wide range of temperature compared with organic solvents commercially used. Therefore, when they can be used as electrolytes, it can make more safe battery than commercial one. In this study, a series of ionic liquids was synthesized and ionic liquids were soaked into microporous P(VdF-HFP) membrane, the polymer electrolytes were also prepared. Microporous membrane was prepared by phase inversion method. Their thermal stability was preformed by TGA and their electrochemical properties were evaluated with ionic conductivity, electrochemical stability and cyclic voltammogram.

In order to strengthen objectivity and availability of oriental herb medicine, the standard formula for herbs has been attempted to set up by experimenting and documentary testing original herbs which were recorded in authorized document. The object herb medicines are Platycodi Radix. The internal morphological standard in this study is expected to supply the search for several physiochemical reaction, biological reaction, determination of indicator material and identification of gene with basic sources in the future. The result of study is as follows; In the shape of real herbs, I compared current herbs in market with original herbs which were just collected or were on the course of drying. It was possible that the internal shape could be identified by using microscope after butanol series. In powder herbs, it was possible to purify the shape by microscope through maceration of natural and powder herbs. Despite such a useful character, it was difficult to deal with powder herbs because it was uncertain to make a standard for them on account of the crush of these tissue. Since powders shape of herbs in a few documents were regard not as the powder shapes of natural herbs but as the maceration state of them. It is suggested that we should inspect the original herbs which are not crushed yet with a microscope in order to identify crushed shape of powder herbs from now on. An Additional standard establishment including physiochemical reaction and gene research is required in order to supplement the fault of this search.
