기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

藥用Sulfonamide 類의 Schiff 監基의 合成과 抗菌作用

金鍾潤,張億奎,田應鎬 嶺南大學校府設 基礎科學硏究所 1983 基礎科學硏究 Vol.3 No.-

Twelve new Schiff bases were synthesized by condensation of two kinds of medicinal sulfonamides with eight kinds of aromatic aldehydes. They were identified by means of the elemental analysis, and UV and IR spectrochemical analyses. Antibacterial activity of the Schiff bases was tested in vitro against one gram-positive and seven gramnegative bacterial species. The results show that some of the compounds are more effcetive than each of corresponding sulfonamides against gram-positive St. aureus, exerting more remarkable activity compared to that against the gram-negative species. Therefore, the mechanism of action of the Schiff bases seems to be different from that of medicinal sulfonamides.

The two processes of R-1 process(anaerobic/anoxic/aerobic reactor) and R-2 process(anoxic/aerobic reactor) were investigated into the operating strategy of the four kinds of HRTs(4, 6, 8, and 10hr) using the raw sewage in Janglim WWTP The sewage contained various refractory wastewaters such as, leachate, industrial wastewater, pigment wastewater. The purpose of this study was find out to the optimal process that was enhanced to remove not only organic compounds, but also nitrogen and phosphorus, when the influent was used to the refractory sewage. As the range of COD^cr, loading rate during operating days was from 0.66kg/m^3/day to 1.63kg/m^3/day, the effluent concentration was 52.0 ~77.0mg/L in R-1 process and 59.0~81 0mg/L in R-2 process, respectively. Increasing the NH_4^+-N loading rate from 126.5g/m^3/day to 326.3g/m^3/day, the removed loading rates were 116.5~196.4g/m^3/day of R-1 process, and 117.7~191.6g/m^3/day of R-2 process, respectively. The removals of organics and NH_4^+-N of R-1 process were slightly higher than those of R-2 process, but the differences were almost negligible. The phosphorus removal efficiency was 50. 5~34.0% of R-1 process and 40.5 ~25.5% of R-2 process, respectively. The difference of the phosphorus removal efficiency was considered because of the effect of phosphorus release in anaerobic reactor and phosphorus uptake in aerobic reactor by facultative bacteria as well as higher COD_cr,/TP ratio in anoxic reactor of R-1 process by 40% by-pass. Hence, the results of this study showed that R-1 process with by-pass was more suitable for nutrient treatment than R-2 process. The submerged fixed-biofilm packed with SAC media could be applicable for the refractory wastewater treatment.

김현수,김치년,원종욱,차봉석,이경종,노재훈 大韓産業醫學會 2006 대한직업환경의학회지 Vol.18 No.2

목적: 본 연구는 염화비닐 및 폴리염화비닐수지 제조공장의 VCM 노출 근로자들을 대상으로 소변 시료채취 시기에 따른 요중 TDGA 농도의 변화를 알아보고자 하였다. 방법: VCM 및 PVC 제조공장 남성 근로자 31명을 대상으로 공기중 VCM 개인노출평가를 실시하였으며 소변내 TDGA 배설 양상을 알아보기 위해 3일 휴식 후 척 작업 시작 전(TDGA1), 1일 작업종료 후(TDGA2), 1일 작업 한 다음날 작업 전(TDGA3) 소변을 채취하였다. VCM에 노출되지 않은 대조군 30명에 대해 작업종료 후 소변을 채취하였다. 공기 중 VCM의 측정 및 본석은 NIOSH 공정시험법 No. 1007에 따라 실시하였다. 요중 TDGA 분석을 위하여 소변을 trimethylsilyldiazomethane(2.0 M in diethyl ether)으로 메틸화 반응하여 가스크로마트그래피/펄스불꽃광도검출기로 분석하였다. 결과: VCM 노출 후 요중 TDGA가 배설되어 감소하는 시기를 조사하기위해 대조군과 VCM 노출 근로자들의 3일 휴식 후 작업 시작 전 요중 TDGA 농도 (TDGA1)를 비교한 결과 각각 0.179±0.271 mg/g creatinine, 0.218±0.443 mg/g creatinine으로 통계학적으로 유의한 차이가 없었다. 1일 작업 종료 후 요중 TDGA 농도(TDGA2)는 0.434±0.623 mg/g creatinine, 1일 작업 한 다음날 작업전 요중 TDGA 농도(TDGA3)는 0.767±1.056 mg/g creatinine으로 순차적으로 증가하였다. 하루 노출량을 평가하기 위해 공기 중 VCM 농도와 요중 TDGA와의 단순회귀분석 결과 1일 작업한 다음날 작업 전 요중 TDGA 농도(TDGA3)와 공기 중 VCM 농도와의 관련성은 R^(2)=0.4215로 1일 작업종료 후 요중 TDGA 농도(TDGA2)보다 높았다. 결론: VCM 노출 후 3일이 경과하면 대조군의 요중 TDGA 농도 수준으로 감소하여 요중 TDGA의 배설 반감기가 3일 이내인 것으로 판단된다. 또한, 하루 근무하고 그 다음날 작업 전에 채취한 요중 TDGA 농도(TDGA3)가 전날 근무시의 VCM노출량과 상관성이 가장 높아 하루 동안의 VCM노출을 평가하기 위한 유용한 생물학적 지표로 사용할 수 있을 것으로 판단된다. Objectives: The study was performed to investigate the changes of urinary thiodiglycolic acid (TDGA) concentration in workers exposed to vinyl chloride monomer (VCM) according to the time of sampling urine. Methods: The personal exposure to airborne VCM was assessed and urinary TDGA concentration was sampled in 31 workers employed in a VCM and polyvinyl chloride (PVC) manufacturing factory. Urinary TDGA was sampled three times: before the start of the shift after 3 days off (TDGA 1), after the end of the first-day shift (TDGA2) and before starting the following day shift after completing the one- day shift (TDGA3). Urinary TDGA in 30 workers who had not been exposed to airborne VCM was sam- pled after the end of the shift. A gas chromatography/pulsed flame photometric detector (GC/PFPD) was utilized to analyze TDGA concentration in urine after the urine was methylated with trimethylsilyldia- zomethane (2.0M in diethyl ether). Results: The creatinine level was 0.179±0.271 mg/g in the control workers and 0.218±0.443 mg/g in the workers before the start of the shift after 3 days off (TDGA1), showing no significant difference (p=0.7035). Urine samples were compared according to sampling time in order to investigate the change of urinary TDGA concentration in the case of continuous exposure to airborne VCM. In VCM-exposed workers, urinary creatinine concentration was 0.434±0.623 mg/g in TDGA2 and 0.767±1.056 mg/g in TDGA3, which indicated a gradual but significant increase (p=0.024). In terms of the statistical correlation between airborne VCM and urinary TDGA to evaluate exposure dose per day, of the three urinary TDGA concentrations, TDGA3, showed the highest degree of regression (R^(2)=0.4215) with 8h-TWA airborne VCM concentration. Conclusion: Based on this result, the excretion half-life of urinary TDGA was assumed to be less than 3 days, because the concentration of urinary TDGA at 3 days after exposure to airborne VCM was decreased to the level of urinary TDGA concentration in the control workers. The concentration of urinary TDGA increased in the case of continuous shift, due to the accumulation of residual metabolites of TDGA. It was considered that TDGA3 can be applied as a useful biological index to evaluate the exposure dose of airborne VCM during one day because TDGA3 showed the highest correlation with the exposure dose of airborne VCM in the previous shift day.

The hypothesis that certain central dopaminergic systems may be overactive in schizophrenia has quite generally accepted by many investigators. Studies of monoamine oxidase (MAO), the major degradating enzyme of biogenic monoamine, have provided a focus for recent biological in schizophrenia. This study was set up to determine the alteration of platelet MAO activity and its sexual differences, the change of plasm sex hormone levels and the correlation between platelet MAO activity and plasma sex hormone levels, in 130 schizophrenics, comparing with 197 normal healthy subjects. Platelet MAO activity was determined fluorometrically by the modified method of Kraml, measuring the deamination of kynuramine to 4-OH quinoline, and was expressed as nanomoles of quinoline produced per milligram of platelet protein per hour. At the same time, plasma estradiol, progesterone and testosterone levels wers determined by radioimmunoassay technique, Following results were obtained. 1. Platelet MAO activity is not different in acute schizophrenics, but is low significantly in chronic schizophrenics (63.7% of normal control group). 2. Platelet MAO activity is lower in male chronic schizophrenics(56.06% of control group) than female(64.69%), and the sex difference is significant. 3. Plasma estradiol level is significantly low in male chronic schizophrenics(71.82%). 4. The correlation coefficient between platelet MAO activity and plasma sex hormone levels reveal negative correlation between platelet MAO activity and plasma testosterone level in female chronic schizophrenics. From the results of the study, it is strongly suggested that the sex difference of platelet MAO activity in chronic schizophrenia is related to the alteration of plasma sex hormone levels.
