OBJECTIVES: This study is to see the transition and pattern of the industrial iureal worker, and to develop the prediction model. METHODS: The data of the study are based on the samples from data-warehouse of Occupational Safety & Health Research Institute and are summed monthly from Jan 1986 to Dec 1999. This study data used data mart and Meta data from DW in KOSHA. The prediction model of the injured worker in Industry is designed by using a winters time series method after data preparing (i. e. sample, explore, modify) from DW. RESULTS: Thls predicted model obtained Winters-method multiplicative in exponential smoothing among applied all models, after the tlme series (total 163 months). It showed that the prediction power was 95.5 %. CONCLUSIONS: In the process of exploring the data, totally the rate of industrial injureal workers reduced, and in the yearly circulation, in February and September the number is the lowest but in June, July, October and November the higher. The number of monthly average injureal workers is 8709 (95 % confidence interval 8277, 9140). From the developed prediction model, since Aug 1999 the industrial injureal worker reduced rapidly in Dec 1999 and first period of 2000. But In second period of 2000 the number of the injured workers is increasing. To conclude, as the total economic situation is becoming better in 2000 than In 1999, its is supposed that the injured workers will increase more than the predictive injured workers because of the increase of production rate and labor force.

Tricho-rhion-phalangeal syndrome is characterized by the triad of slow growing, brittle hair and early loss of hair, distinctive faces which include a long philtrum and pear-shape nose, and peripheral cone shape epiphysis with brachyphalangia. Tricho-rhion-phalangeal syndrome is probably not so much uncommon. The tricho-rhion-phalangeal syndrome, however, is not well recognized to orthopaedic surgeons due to the minor finger deformities. We report a case of tricho-rhion-phalangeal syndrome with brief review of literature.

ONJECTIVE: This study was carried out to investigate the epidemiologic characteristics and magnitudes of scrub typhus (tsutsugamushi disease) in Gyeongsangbuk-do, Korea. METHODS: Resources of data collected were epidemiologic surveillance report to public health centers on each disease occurrence. The authors reviewed 344 epidemiologic surveillance reports for cases of scrub typhus developed in Gyeongsangbuk-do, Korea from Jan 1, 1999 to Dec 31, 2001. RESULTS: The scrub typhus cases were 376 during three year period, and the incidence was significantly higher in the county area than in the city area. Incidence of scrub typhus was increasing each year. In 344 epidemiologic surveillance reports, the job of the cases was farmer (67.2%), housewife (4.7%), clerk (3.5%). Two hundred ninety eight cases (86.6%) have experienced outdoor activities before development of the scrub typhus. The outdoor places of exposure were dry field (64.8%), rice field (51.7%), hill (12.8), and grass field (9.7%). The symptoms reported were fever (93.3%), headache (83.7%), chill (69.5%), and rash (54.4%). CONCLUSIONS: Incidence of scrub typhus was increasing in Gyeongsangbuk-do, Korea, this phenomenon may be related to change of climate, the reporting rate of disease and outing activities. Good surveillance and adequate analysis of epidemiologic data is a essential for the prevention of the disease. With this result, high risk population was identified and effective intervention should be done to prevent the disease.

Recent studies suggest that coronary endothelial dysfunction in atherosclerosis may contribute to the predisposition both for coronary spasm as well as for thrombus formation. The integrity of at least one aspect of endothelial function can be assessed by the intracoronary administration of acetylcholine. Eleven(13.4%, mean age 48+13, male 11) out of 82 consecutive patients with acute myocardial infarction showed angiographically normal or near normal coronary arteries at 7~10 in-hospital days. Ten(91%) had history of heavy smoking and 7 patients(64%) had no history of previous angina. Anterior myocardial infarction was in 8 and inferior in 3 patients. After intracoronary administration of acetylcholine(incremental dose of 20, 50ug for the right and 20, 50, 100ug for the left), 9(82) of 11 infarct related arteries showed total or subtotal occlusion, but only in 3(17%) out of 18 non-infarct related arteries of 10 patients. Multivessel spasm was noticed in 3. Ergonovine test(graded doses of 0.05, 0.1 and 0.2 mg intravenously) was performed 30 minutes after completion of acetylcholine test in 5 patients. In 1 patients, acetylcholine test was positive and but ergonovine test was negative. Conclusion : 1) Eleven(13.4%) out of 82 patients with acute myocardial infarction had angiographically normal coronary arteries. 2) Ach positive responses of infarct-related arteries are more frequent(82%) than that of non-infarct related arteries(17%), suggesting that the infarction might be related to coronary artery spasm. 3) Positive Ach responses of non-infarct related arteries occurred in 30% of Patients. 4) Ach and Erg induced vasospasm developed at the same site in 5, which suggests that local hyperreactivity might be related to spasm.
