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.

This paper presents a state of the art review of various researches and applications on collaborative design systems. From the review we intended to understand current technical fruits and emerging issues on both researches and commercial applications. The purpose of this paper is not to develop any collaborative design systems but to give a insight of design-construction ICT edges to small and medium sized architect's offices. A general classification matrix is proposed to briefly outline the collaborative design systems. At the end we discuss what the architect's offices would do for preparing kaleidoscopic information age. There are technical-pulled and market-pushed forces to introduce architectural design practices, the collaborative design system. In the first place a proper commercial system would be selected and turn into practical use for project management. The system should support data(file) sharing, on-line file transaction, available groupware, and recommended web-based. In parallel the shift of legacy CAD to object-based parametric CAD would be accepted smoothly in small and medium sized offices. Politics such as division of modeling works by CAD system, rules of data handling, and layer coordination etc. would be established in advance when the office decides to use object-based CAD systems.

Postweaning multisystemic wasting syndrome (PMWS) is a new emerging disease in swine herds world wide, and porcine circovirus type 2 (PCV2) is known as a major cause of PMWS. In this study, the prevalence of PCV2 Rep gene was examined for the serum, nasal swabs and feces collected from 30 heads of piglets affected with PMWS and 10 heads of normal healthy piglets using polymerase chain reaction (PCR). The diagnostic efficiency of the PCR was evaluated for different types of samples. Rep gene of the isolate (PCV2 S1) was then sequenced. In the group of PMWS-affected piglets, the prevalence of PCR-positive were 70.0% in sera, 33.3% in nasal swabs and 0% in feces. In the normal healthy group, the PCR-positive rates of sera, nasal swabs and feces were 30%, 20% and 0%, respectively. Seven piglets (17.5%) out of 40 showed the simultaneously positive results in both of sera and nasal swabs. The nucleotide sequence homology of Rep gene of PCV2 S1 as compared with the reference strain of PCV2 (GenBank accesson no.AF027217) was 99.3%.
