Of 2,740 industries in Jeonbug area which are covered by industrial insurance policy, 462 facilities which the accidents related to industry occurred during the year of 1979 were studied, and the results are summarized as follows; 1. The accidents related to industry occurred in 462 industries of the total 2,740 industrial facilities in Jeonbug area as of 1979. 2. The incidence rate accident per 1,000 workers was 34.3(49.2 in male workers and 12.8% in female workers), the frequency rate of the total industries in Jeonbug area was 13.36, and severity rate was 1.3. 3. The frequency rates and severity rates by type of industry in study area were quit different to compare with those of national rates. 4. The incidence rate of construction industry was 223.6 per 1,000 workers, and that of transportation-communication industries were 78.6. 5. The proportion of industrial accidents of 20-24 age group was 22.1 percent of the total accidents, and the proportions decreased according to age increase. 6. The incidence rate in the industry having less than 49 workers was 20.6 per 1,000 workers, that of industry with 50-99% workers was 26.7, that of industry with100-199 was 51.9, that of industry with 200-499 was 80.2 and that of with more than 500 workers was 40.7. 7. The accidents which occurred in the workers with experience of less than one year was 69.4 percent of the total accidents, otherwise, the longer the workers have worked the less accident they have. 8.The most accidents occurred in the shift between 10 to12 o'clock, and 16 to 18 hour. 9. The primary causes of the industrial accidents were found to be collisions, machinery, falling objects and falls. 10. The site of injury by type of industry were quit different, and the major site of injury was finger. 11. The laceration and open injuries of the accidents related to industry were 37.2 percent of the total ceases, and fractures or dislocations were 28.5 percent, and contusions were 6.5% percent. 12. Death rate of industrial accident was 5.0 per 1,000 workers, and those of industry were 47.6 in transportation, 42.8 in construction industry, 24.4 in mine industry, and 2.0 in manufacturing industry.

To assess the immunological function of toluene exposed group, the proportions of T lymphocyte, B lymphocyte, CD 4 cell, CD 8 cell, the ratio of CD4 to CD8 (CD4/CD8) in peripheral blood were measured on twenty-one toluene exposed workers and twelve healthy workers who did not have previous history of toluene exposure. In addition, to evaluate the present status of toluene exposure, urinary hippuric acid concenturations were measured in exposed group. The mean concenturation of urinary hippuric acid was 2.84 g/creatinine g in exposed group. The proportions of T lymphocyte, B lymphocyte, CD8 cell and CD4/CD8 of exposed group were slightly lower than non-exposed group except the proportion of CD4 cell which was similar in both groups. But these differences were not statistically different in both groups. The proportions of T lymphocyte and CD4 cell were significantly correlated with the length of duration in exposed group (P<0.05)

The study conducted from May to September in 1994 to investigate applicability of the Hearing Handicap Inventory for the Elderly-Screening version(HHIE-S) in parallel with the puretone audiometer to the initial screening test of noise-induced hearing loss(NIHL) in some noise-exposed workers. Subjects were selected by systemic sampling that took every fifth person from 6,700 workers taking the annual occupational health examination by the department of Health Maintenance of Dongsan Hospital Keimyung University in Taegu. The authors administered the pure-tone audiometric test and self-reported questionnaire of HHIE-S including items of sociodemographic and job-related variables concurrently. The final subjects analysed were 1,019(488 males and 531 females) excluding fourteen persons who had many missing values in their questionnaires. The reliability coefficients of HHIE-S scale by Cronbach's alpha were 0.84. In the univariate analysis of hearing handicap measured by the HHIE-S, work duration, military service and the hearing threshold loss at 1kHz and 4kHz was the only selected variable explaining the hearing handicap in males and hearing threshold loss at 1kHz and 4kHz, age, and work duration were selected in females. In ROC curves for HHIE-S scores against NIHL as gold standard which was defined by the follow-up audiogram as more than 30dB of the average of 0.5/1/2kHz and 50dB at 4kHz, the optimal cutoff for the parallel HHIE-S appeared to be 8. The results suggest that HHIE-S appeared to have some reliability and validity in this data and might be used in screening NIHL in parallel with pure-tone audiometer in noise-exposed workers.

We studied the expressions of E-cadherin, MMP-7 and CD44V in colorectal cancer and their corresponding normal mucosa using RT-PCR. From the 26 patients whom a com parative study of clinical and histopathological data is available, MMP-7 and CD44V were significantly enhanced in cancer and their metastatic tissues, compared with their normal mucosa. E-cadherin did not reveal any difference between cancer and normal mucosa. The relashionship between these genes and colorectal cancer development can not be confirmed by this study, however CD44v and MMP-7 may be associated with metastasis of colorectal cancer.

Human Papillomaviruses(HPVs) are regarded as sexually transmitable and closely associated with precancerous lesions or invasive cancers of the vulva, vagina, and cer V1X. In situ hybridization, besides showing higher sensitivity, allowed the identification of specific viral types. We studied 12 cases of condylomata accuminata for HPV typing by in situ hybridization techenique. Ten cases(83.3 % ) showed positive for HPV type 6/11, and 2 cases(16.7% ) were positive for HPV type 16/18.
