Lead poisoning is still prevalent and one of important occupational disease in Korea. To prevent undue high lead burden and maintain good health condition of lead workers in lead using industries, periodic health examination and regular biological monitoring of lead workers are often required in addition to the fundamental improvement of their working condition. To evaluate the effect of comprehensive occupational health program with regular biological monitoring on the level of lead exposure of lead workers in lead using industries, 11 year database from 1983 to 1994 of one storage battery factory was reviewed. From 1983 to end of 1986 only periodic health examination was provided to the lead workers, but from 1987 comprehensive occupational health program with regular biological monitoring was provided to maintain better health condition of lead workers. Selected study variables for lead exposure were blood lead(PbB), zinc protoporphyrin in blood(ZPP), δ-aminolevulinic acid in urine(ALAU), hemoglobin(Hb), hematocrit(HCT). Information on sex, age and work duration was also reviewed. 5 years data from 1983 to 1987 and 3 years data from 1990, 1993 and 1994 were available for all lead exposure indices except ALAU which has only 5 years data from 1983 to 1997. The results of 11 years longitudinal observation of lead indices are all follows: 1. The mean value of ZPP of lead workers in 1983 was 148.7±73.1 ㎍/㎗(Male: 145.5±72.3, Female: 168.1±79.1), whereas that of ZPP of lead workers in 1994 was decreased to 64.3±32.7 ㎍/㎗(Male: 60.2±28.8, Female: 95.2±43.4). 2. The mean value of PbB of lead workers in 1983 was 56.4±18.8 ㎍/㎗(Male: 55.59±19.1, Female: 59.6±19.1), whereas that of PbB of lead workers in 1994 was dcreased to 35.4±11.9 ㎍/㎗(Male: 35.7±12.0, Female: 32.8±10.8). 3. The mean value of Hb of lead workers in 1983 was 14.1±1.4 g/㎗(Male: 14.4±1.1, Female: 11.7±0.8), whereas that of Hb of lead workers in 1994 was increased to 15.6±1.5 g/㎗(Male: 15.9±1.2, Female: 12.9±1.1). 4. Blood lead is most highly correlated with ZPP(r=0.522, male:0.54 and female:0.50) and also correlated with ALAU and work duration also. 5. The simple regression analysis of PbB and ZPP showed different coefficient of regression by the measurement year, but there was no difference of coefficient of regression between sex. The slope of equation of pooled data for 1983-1986 without comprehensive occupational health program was 2.16 and differed from that of pooled data for 1987-1994(1.25). This difference suggests that the unit effect of blood lead on ZPP was relatively smaller in later period of comprehensive occupational health program than carly period without comprehensive program. The slope change in the analysis of linear regression of PbB on ZPP in lead workers can be used to evaluate the possible effect of health intervention to prevent undue high lead absorption in lead using industries. 6. 11 years occupational health service in this storage battery factory brought out considerable improvement of health status of lead workers in terms of decrease of PbB and ZPP and increase of Hb and the improvement was more remarkable after the introduction of comprehensive occupational health program.

Soviet studies in Korea witnessed, in the 1960’s, a continuing folw of the Soviet case, as indeed of other cases. In the 1970’s and the 1980’s it also witnessed a folw of studies of another, newer, and broader type-studies of theoretical bent concerned with the construction of general analytical models of Soviet studies. Accordingly, the purpose of this paper is to review and examine the general trends and problems of Soviet studies in Korea. In order to cahieve the purpose, the reviewer consider in three parts firstly, what was the basic motive of Soviet studies in Korea, especially in the 1960’s; secondly how Soviet studies in Korea developed during the 1970’s and the 1980’s; finally, what are the problems to study Soviet Affairs in Korea. In terms of the difficult problems to study soviet affairs in Korea, the reviewer insisted that one of the most urgent tasks confronting the field of Russian studiesin korea be the identification and preservation of the primary source materials that document the domestic and external affairs.

This study is to simulate the future water quality(BOD) of the Geum river by the development works in the west coastal area. The development works in the Geum river basin consist of 14 works including 4 industrial complexes, 1 agricultural development district and 9 agricultural-industrial areas. A simulation for predicting the future water quality of the Geum river from year 1996 to 2001 is performed by using the QUAL2E model. In this case the flow condition is assumed that the river maintenance water of main river is discharged 20㎡/sec from the Daechong dam and tributaries are maintained the 330-th daily flow in descending order. From the results of water quality simulation, the construction of wastewater treatment plants in the upper reaches of the Geum river was not effective enough to improve the water quality of downstream part below Buyo 1. It is necessary to construct more wastewater treatment plants in the lower reaches of the stream for improving the water quality of the Geum river.
