본 연구에서는 도시화로 인한 유출특성의 변화를 정량적으로 분석하고자 하였으며, 유출해석 모형으로는 선형저수지 모형을 선택하였다. 1960년대 이후 급격한 도시화를 겪었던 부산지방의 온천천 유역을 연구대상유역으로 선택하였으며 몇 가지 경우에 대한 유출해석을 수행하였다. 연구대상유역은 두 개 지점에서의 유량자료를 갖고 있다. 한 관측소(세병교 지점)는 현재의 자료를 갖고 있으며, 다른 하나(이섭교 지점)는 1972년의 측정자료를 보유하고 있다. 선형저수지 모형은 두 지점에서의 홍수수문곡선을 잘 재현하였으며, 대상유역에 대한 그 적용성을 입증하였다. 유효강우량 산정법별로는 Φ-index 법이 일정비손실법보다 더 나은 결과를 준다는 것을 알 수 있었다. 이섭교 지점에서 과거 측정된 홍수수문곡선과 모의를 통해 계산된 수문곡선을 비교함으로써 약 20년간에 걸친 도시화로 인하여 첨두홍수량의 크기는 증가하고 유역의 평균 지체시간의 크기는 감소하였다는 사실을 확인할 수 있었으며, 이를 정량적으로 평가할 수 있었다. This study was to figure out the runoff characteristics changes due to urbanization. The linear reservoir model was chosen and runoff analyses for several cases were conducted for the purpose. The On-Cheon stream watershed in Pusan was selected as its study area, which has experienced a radical urbanization since 1960's. There were two gaging stations in the study area one had the recent flow data and the other kept the flow data observed in the past. The linear reservoir model regenerated flood hydrographs well for both of the gaging stations and its applicability to the study area was proven. The results of runoff analyses were investigated depending on methods for estimating effective rainfall or rainfall excess. The Φ-index method provided better results than the constant percentage method. The comparisons of hydrograph observed in the past with the simulation results at the Ie-Seop Bridge site revealed that the peak discharges had increased and the mean lag of the study area had decreased due to the urbanization for two decades, and made it possible to evaluate the effects of urbanization quantitatively.

It is difficult to make an exact estimate of the peak discharge, the runoff depth of flood, and establish the proper measurement for the flood protection since the water stage or discharge has been rarely measured at medium or small river basin in Korea. Therefore, Runoff analyses were perfomed using the storage function method, the discrete, linear, input-output model and linear reservoir model, respectively. Various parameters for the study areas were determined. The calculated hydrographs by three methods showed good agreement with observed flood hydrographs. The capabilities of regenerating flood hydrographs were evaluated based on rainfall from the storage function parameters, the Ø-index method, and the constant percentage method. The storage function parameters provided better effective rainfall for regenerating flood hydrographs than any others considered in the study. 우리나라의 중소하천 유역 중 대부분은 수위나 유량 관측을 행하지 않은 미계측 유역으로 방치되어 있는 상태이므로, 홍수시 정확한 유출량의 추정, 홍수피해 경감을 위한 적절한 대책 수립 및 수공구조물의 건설에 필요한 계획홍수량의 산정 등이 극히 어려운 실정이다. 따라서 본 연구에서는 수영강유역을 대상으로 기존의 유출해석 모형 중 저류함수법, 선형 이산화 입력-출력 모형 및 선형저수지 모형을 채택하여 유출해석을 실시하고, 대상유역에 대한 각종 매개변수를 산정한다. 유출결과로부터 세가지 방법에 의한 계산수문곡선은 실측수문곡선과 잘 일치하였다. 또한 저류함수법 매개변수를 이용한 방법과 Ø-index법 및 일정비손실법 등의 유효강우량 산정방법에 따라 수문곡선의 재현능력을 평가하였다. 본 연구에서는 저류함수법 매개변수를 이용한 방법이 가장 양호한 재현결과를 나타내었다.

방향족 탄화수소인 tnmethylbenzene (TMB)은 그 사용량이 늘어갈 뿐 아니라 직업적으로 폭로되는 양도 증가하고 있으므로 생물학적 모니터링 및 흡수, 대사, 배설에 관한 연구가 중요시되고 있다. 일반적으로 TMB는 간의 산화효소에 의해 하나의 메틸기가 산화되고 이것은 glycine과 포합되어 배설되는 것으로알려져 있다. 본 연구에서는 1,2,4-TMB의 대사체를 합성하고, 모세관의 전기영동법으로 분석할 수 있는 방법을 개발하였다. 모세관 전기영동법으로 흰쥐의 뇨 중에서 1,2,4-TMB의 대사체인 3,4, 2,4, 2,5-dimethylbenzoic acid 및 3,4 2,4 2,5-dimethylhippuric acid를 분석하기 위하여 내경 75㎛, 총길이 35cm (검출기까지 29cm)인 용융실리카 모세관을 15℃로 유지하면서 양단에 10kV의 전압을 걸어주고, 전해질로는 15mM β-CD, 3% 2-프로판올을 포함하는 01m 인산완충액 (pH 7)을 사용하였으며, 검출신호는 UV 210nm와 254nm에서 동시에 모니터링하였다. 뇨 시료의 분석 결과 배설된 1,2,4-TMB의 대사체의 상대량은 3,4-이성질체가 56.&%, 2,4-이성질체가 30.5%, 2,5-이성질체가 12.8%였다. 이 방법은 노동자의 뇨 분석에도 적용될 수 있을 것으로 생각된다. The metabolites of 1,2,4-trimethylbenzene (TMB) were synthesized and determined by capillary electrophoresis (CE). The optimum conditions of CE for the separation and determination of 3,4-, 2,4-, 2,5-dimethylbenzoic acid and 3,4-, 2,4-, 2,5-dimethylhippuric acid from the rat wine were as following: the fused silica capillary(75μm i.d. X 36 cm length, 29 cm to detector) was used and kept at 15℃ The applied voltage was 10kV and compounds were detected at UV 210 nm and 254 nm. The running electrolyte was 0.1 M phosphate buffer (pH 7) contalI1ing 15 mM of β -CD and 3% of 2-propanol. The relative amount of the metabolite of 1,2.4-TMB in the rat urine was 56.7% of 3,4-isomer, 30.5% of 2,4-lsomer and 12.8% of 2,5-isomer. This method can be applied to the analysis of TMB-metabolites in human wine.

Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

88 workers exposed to cadmium were examined at the 12 factories using or producing cadmium in order to know the present state of cadmium exposure and renal dysfunction in 1992. Cadmium in blood and in urine were measured and compared by the 3 exposure level of cadmium in air. Cadmium in blood of low, moderate and high exposure group were 2.5, 3.8 and 7.6 ㎍/L, respectively. Cadmium in urine were 1.8(1.3), 3.8(2.6) and 7.9 ㎍/L(6.1 ㎍/g creatinine), respectively. However, there was no relationship between urinary cadmium and β₂-microglobulin. Cumulative exposure estimate(CEE) was calculated by multiplying the mean ambient cadmium level of the factory and working duration. CEE has a high correlation with cadmium in blood and urine, but no relation to β₂-microglobulin. Because working durations were relatively shorter than European workers', the highest CEE was just 300 ㎍·year/m³, which was not enough to induce renal tubular dysfunction. This study, however, suggested the possibility that renal tubular dysfunction caused by cadmium could be happened in Korea in the near future.

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

Twenty-four factories registered at the Ministry of Labor as factories using or producing cadmium in 1991 were investigated to know the present state of occupational exposure to cadmium in 1992. Nine factories among 24 stopped using or changed to other substances and 1 factory didn't produce any more, but delivered it to other factories through imports. Therefore, only 14 factories were producing or using cadmium. But, alloying materials were supplied to about 20 and more factories, however, they couldn't be investigated because of limited information. Three factories had less than 50 workers were 3,6 had 50-300 and 5 had more than 300. About 167 workers were exposed to cadmium. According to the classification by process, there were 4 alloy processes, 2 refinary, 2 elctroplating, 2 dry cell making, 1 industrial battery making, 1 duplicator drum making, 1 recycling of battery and 1 copper refinary. 8 factories used metal cadmium, 3 cadmium oxide, 2 cadmium sulfide, and 1 cadmium hyroxide. One factory was importing cadmium stearates only and supplying them to the PVC making factories. The amount of metal cadmium producing in 2 refinary factories was about 50-65 ton per month. The other cadmium compounds were imported. According to exposure level of cadmium air of the 10 factories examined, each factory could be divided into high, moderate and low exposure groups. 1 battery recycling factory and 3 alloy factories were in the high exposure group and their mean air concentrations were 0.06679, 0.05481, 0.02492, and 0.003㎎/㎥, respectively. Refinary and industrial battery making factories were in the middle exposure group and their mean air concentrations were 0.00773 and 0.00613 ㎎/㎥, respectively. Finally, low exposure group were copper smelting, dry cell case making, duplicator drum making and electroplating factory and their mean air concentrations were 0.00096, 0.00071, 0.00057 and 0.00054 ㎎/㎥ respectively.
