The air pollution by acid pollutants is problematic is the whole world. Acidification of water has already been deteriorating the forest ecosystem. This study was conducted to analyze the acidity and chemical composition of the open precipitation and throughfall at forests affected by heavy traffic. The sites of this study were forest stands (Quercus mongolica, Pinus rigida) in the proximity of a heavy traffic road and forest stands of same species at a distance of 4 km from the highway. The results are as follows; The open precipitation pH was lowest in Seochun. The throughfall pH showed some buffering capacity only in Quercus mongolica stands. In Purus rigida (Shingal and Seochun) stands, there was little difference from the open precipitation. Chemical composition of the open precipitation for each sampling site showed that ion concentrations of Ca^(2+), NH_(4)^(+) and SO^(2-)_(4) had higher value than other ions, and except these ions, the small quantity of ions showed different properties specific to each site. Changes of ion concentrations in the throughfall showed a tendency to increase. Ion concentrations of the throughfall increased with washout and nutrient leaching from the trees.

GroE that is a heat shock protein composed of GroEL and GroES is known as an immunodominant target of both the humoral and cellular immune responses in bovine brucellosis. This study was carried out to characterize groE gene encoding heat shock proteins of B. abortus isolated in Korea and to evaluate the immunogenicity of the GroE protein expressed in E. coli system. In PCR the specific signals with the size of 2,077 bp were detected in five strains isolated from the mammary lymphnodes of the dairy cattle that were serologically positive and the reference strains. In comparison of the sequences of nucleotides and amino acids among the strains, GroES showed 100% identity in both sequences. GroEL was evaluated 99.0∼99.9% in nucleotides and 98.0∼100% homology in amino acids. The groE gene including groES and groEL was inserted into pET29a vector and constructed pET29a-GroE recombinant plasmids. The inserted groE was confirmed by digestion with Ncol and EcoRl endonucleases and nucleotide sequencing. E. coli BL (DE3) was transformed with pET29a-GroE, named as E. coli BL (DE3)/pET29a-GroE. In SDS-PAGE, it was evident that the recombinant plasmid effectively expressed the polypeptides for GroES (10 kDa) and GroEL (60 kDa) in 0.5, and 2 hours after IPTG induction. The immuno-reactivity of the expressed proteins were proved in mouse inoculation and Western blot analysis.

The importance of forest ecosystem has been raised as the recognition of the environmental problem is increasing. This study was carried out to investigate biomass of each organs(stem, branch, needle) of Pinus Koraiensis plantation if Kwangjugun, Kyunggido, Korea. The maximum values of stem length, and biomass for stem, branch and needle were shown at 6 to 8m height layer. Tree form is conical as usual for typical conifers. This growth pattern shows that crown has been formed, developed and destroyed from time to time. The biomass for each of the organs was distributed as follows : 53.83% by stem, 27.63% by needle and 18.50% by branch. This indicates that most of the biomass are allocated to the bottom part of the organs, which contributes to conical shape of the tree.

This study was carried out to compare pH and chemical properties of dew in three forest stands(Mt. Nam-Seoul, Shingal-Yongin, Hangdong-Pyungchang)from May, 1998 to September, 1999. The results of this study were as follows; The acidity of dew in Seoul, which has a metropolitan environment, measured pH5.57±0.41. The highest acidity was measured in Yongin(pH5.50±0.96), while pH in Pyungchang was 6.36±0.57. Ion concentration in Pyungchang was lower than in other two regions, with a similar tendency of seasonal cation changes to those in Seoul and Yongin. Anion changes in Pyungchang, however, was inconsistent with those in other two regions. Although analyses of correlation coefficients showed that there was no significant correlation between overall ion concentrations and pH of dew, there was highly significant correlations between some cations and anions in Seoul and Yongin, leading a suggestion that those ions were coupled from one source.

A hand-arm vibration syndrome, local vibration illness, occurs in some workers who use hand held vibration tools. It consists of white fingers, diffusely distributed finger neuropathy, pain in the hand and arm, and a small excess risk of osteoarthritis. This study is aimed to identify effective methods to confirm local vibration illness among various health exams, which are mentioned in worker's special health exam regulation. In addition, this study is aimed to quantitatively assess the daily vibration exposure level as a major determinant of vibration illness. The subjects, 46 vibration workers, were selected according to the results of the first special health exam about vibration hazards at shipbuilding industry in 1997. They all had experiences of work related blanching of fingers. Fifteen controls, who had no vibration exposure at all, were also recruited to compare their test results with the results of vibration workers. We adopted I subjective and 6 objective tests to evaluate the effectiveness and feasibility for confirming local vibration illness. These tests were history taking of subjective symptoms according to the Stockholm classification, checking blood pressure of finger, checking grasp power, checking finger skin temperature, nail-bed pressing test, vibration perceptional threshold test, and skin prick test for pain perception. Among these, checking skin temperature, nail-bed pressing test, and vibration perception test included cold water provocations. We also estimated some vibration exposure levels of hand held vibration tools by using previously published data from one automobile company. In conclusion, history taking of subjective symptoms according to the Stockholm classification, nail-bed pressing test, and vibration perceptional threshold test were discovered to be effective to diagnose local vibration illness. Furthermore, vibration perceptional threshold on right fingers showed a dose-response relationship to daily vibration exposure levels. The parameter β was 0.0005(±0.0002), and statistically significant by REM(random effects model).
