Antineoplastic agents may exhibit effects not only in patients therapeutically exposed, but also in health workers who prepare and administer these drugs. This study was done to clarify whether nurses who handle anticancer drugs show signs of drug absorption. The experimental group was 14 nurses handling anticancer drugs at three medical wards of a hospital in J city ; the control group was 12 psychiatric nurses at the same hospital. The test materials were the nurses' 24hr urine specimens, which were concentrated by XAD-2 column chromatograpy. Tester strains were TA98(±S9mix), TA100(±S9 mix), TA1535(±S9 mix) and TA1537(±S9 mix) : the salmonella mammalian microsomal test (Ames test) was used for the urinary mutagenicity assay. The results are summarized as follow : 1. In qualitative analysis of the results, both experimental group and control group showed 15.4% urine toxicity. 2. The experimental group revealed significantly higher urinary mutagenicity both in the activation method test and non-activation method test of the tester strains TA98, TA100 and TA1535. In the case of TA1537, the two groups showed no difference in the non-activation method test, but the activation method revealed a difference. 3. In urinary mutagenicity of the experimental group by ward career, there was a significant difference between the group with more than 20 months experience and the group with less than 20 months on the tester strains TA98, TA100, and TA1537. No Significant difference was found between two groups by the tester strain TA1535.

Purpose: This study was done to identify the effects of Qi hand reflexology on autonomic nerve activity in patients admitted to hospital. Method: A non-equivalent control group and quasi-experimental research with pre/post test design were used and 59 patients on a medical ward were assigned to either the experimental group (32) or the control group (27). The study variables included vital signs, autonomic nerve activities (ALF (absolute low frequency), AHF (absolute high frequency), nLF (normalized low frequency), nHF (normalized high frequency), SDNN (standard deviation of all normal-normal intervals)) and were evaluated using the QECG-3 system. The experimental group was treated with Qi hand reflexology for 10 minutes per day, for 3days. Results: Skin temperature and systolic blood pressure in the experimental decreased with treatment. ALF, AHF and SDNN for the experimental group increased with regulating proportion (nLF: nHF=6:4) and a significant difference between the groups was observed. Conclusion: The results indicated that application of Qi hand reflexology for patients in the hospital is effective in regulating the autonomic nervous system activation. Implication of finding should be useful for future research.

Self Organizing Map (SOM) was applied for pattern classification of hydrological and water quality data measured at Jangseong Reservoir on a monthly basis. The primary objective of the present study is to understand better data characteristics and relationship between the data. For the purpose, two SOMs were configured by a methodologically systematic approach with appropriate methods for data transformation, determination of map size and side lengths of the map. The SOMs constructed at the respective measurement stations for water quality data (JSD1 and JSD2) commonly classified the respective datasets into five clusters by Davies-Bouldin Index (DBI). The trained SOMs were fine-tuned by Ward's method of a hierarchical cluster analysis. On the one hand, the patterns with high values of standardized reference vectors for hydrological variables revealed the high possibility of eutrophication by TN or TP in the reservoir, in general. On the other hand, the clusters with low values of standardized reference vectors for hydrological variables showed the patterns with high COD concentration. In particular, Clsuter1 at JSD1 and Cluster5 at JSD2 represented the worst condition of water quality with high reference vectors for rainfall and storage in the reservoir. Consequently, SOM is applicable to identify the patterns of potential eutrophication in reservoirs according to the better understanding of data characteristics and their relationship.
