With increased use of neurotoxic agents in manufacturing industries, hazardous effects of neurotoxic agents pose significant problems in protecting health of workers who work in these industries. A normal range of neurobehavioral performance is required 10 study hazardous effects of neurotoxic agents among workers. However, such reference for Korean population is not available yet. The objective of this study is to estimate a normal range of neurobehuvioral test performance of female workers in Korea. Data for neurobehavioral test performance developed by the world Health organization were obtained from 165 female workers. Study Subjects, 140 production workers and 25 clerks, who voluntarily participated in this study were not occupationally exposed to neurotoxic agents. The mean age and the mean education years of them were 32 years and 10.9 years, respectively. Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention tests among the Neurobehavioral Core Test Battery(NCTB) were included in the evaluation. Subjects were interviewed by a trained interviewer for their detailed occupational history. Mean(+/-SD) performance of the participants were: 45.7+/-7.1 and 41.9+/-6.4 in the Santa Ana dexterity test of the preferred and non-preferred hands; 191.9+/-38.6 in correct dot of the pursuit aiming test; 57.7+/-16.0 in the digit symbol test; 274.8+/-44.6 msec in the mean simple reaction time and 70.5+/-69.0 msec in the mean standard deviation of it; and 7.8+/-1.7 in the Benton visual retention test. Most neurobehavioral performance scores were correlated significantly with age and educational level. Educational level was found to be a significant independent variable which was associated with all test scores. Age was significantly associated with scores of pursuit aiming and digit symbol tests.

This study was conducted to determine the correlation between weighted needle pinprick sensory threshold(PPT) and sensory nerve conduction tests. The subjects were 53 healthy controls, 31 diabetic patients without peripheral neuropathic symptoms(DM) and 36 diabetic patients with peripheral neuropathic symptoms(DN). PPT was measured on the index and little fingers, bilaterally, as well as under the lateral malleolus, bilaterally. In electrophysiologic assessment the left and right median, ulnar and sural nerves were studied. Each mean PPTs was high in order of controls, DM and DN. Age adjusted PPT was significantly different among three groups on right little finger(p<0.05) and left malleolus(p<(0.05), but not significantly different between DN and DM on other sites. Each sensory nerve conduction velocity and amplitude was statistically significantly different among three groups(p<0.05). Correlations of PPT with sensory nerve conduction velocity and amplitude were statistically significant on each site and ranged from -0.4203(left malleolus) to -0.5649(right index finger) and from -0.3897(left index finger) to -0.6200(right index finger), respectively. When electrophysiological study is not feasible, measurement of PPT may be helpful for the assessment of peripheral sensory neurological function.

The objectives of this research are 1) to access different images held by three consumer groups (patients in university hospital, patients in corporation hospital, persons who are not currently visiting hospitals) on two types of hospitals(university hospitals and corporation hospitals), and 2) to investigate the personal factors affecting images of two types of hospitals. The data for this analysis were collected by questionnaire survey. A total of 403 interviews were conducted. Of these cases, 43 percent are male and 57 percent are female. The major statistical methods used for the analysis are paired t-test, factor analysis and multiple regression. The three consumer groups show a consensus that corporation hospitals are better than university hospitals in some aspects, such as kindness, facilities, and equipments. However, these groups disagree in certain images on two types of hospitals, such as popularity, credibility, and readiness for emergency. The images on two types of hospitals are varied by the respondents' sociodemographic characteristics such as age, sex, and by the type of hospital they are currently visiting.

In order to investigate the level of lead exposure of workers in litharge making industry and to evaluate how lead exposure, personal habit such as smoking and drinking affect the prevalence of lead related symptoms and other study variables, we investigate 114 workers(24 office workers and 90 lead exposed workers) in a litharge making industry. Study variables chosen were blood lead(PbB), zinc protoporphyrin in whole blood(ZPP), Hemoglobin(Hb), hematocrit (Hct), SGOT and SGPT. symptom questionnaires which had 15 lead exposure related symptoms were provided to all workers and filled up by themselves and reconfirmed by physician. The results obtained were as follows; 1. The mean value of PbB, ZPP and SGOT in lead exposed group were higher than those of non-exposed group, and there were no differences of means in other study variables. 2. The smoking and drinking rate of study subjects were 65.8% and 71.0% as a whole. Smoking rates were lower in non-exposed group than exposed group, but drinking rate were not. 3. There were no differences of mean values of study variables between smoker and non-smoker in non-exposed and exposed group, but there was a difference of mean value of SGOT between drinker and non-drinker in lead exposed group. 4. while the symptom prevalence of lead exposed group were higher in neuromuscular category than non-exposed group, those of non-exposed group were higher or same with exposed group in gastrointestinal and general symptom category. 5. The symptom prevalence of smoker were higher than non-smoker regardless of exposure. 6. The symptom prevalence of drinker were only higher in gastrointestinal symptom category than non-drinker. 7. In multiple stepwise regression analysis of lead related symptoms as dependent variable and blood lead, smoking habit, drinking habit and work duration as independent variables, drinking habit contributed to the gastrointestinal symptom category, whereas blood lead and smoking contributed to the neuromuscular symptom category. For the total symptoms work duration and smoking habit contributed significantly.
