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.

Acute organophosphate (OP) poisoning produces cholinergic symptoms resulting from the inhibition of cholinesterase, and the overstimulation of muscarinic and nicotinic receptors in the synapses. The dominant clinical features of acute cholinergic toxicity include bradycardia, miosis, lacrimation, salivation, bronchorrhea, and bronchospasm. All symptomatic patients should receive therapy with oxygen, atropine, and pralidoxime. Atropine works as a physiologic antidote by competitively occupying muscarinic receptor sites, reducing the effects of excessive acetylcholine. Atropine should be immediately administered, and the dose can be titrated according to the severity of OP poisoning. A large dose may be necessary to overcome the excessive cholinergic state in case of severe poisoning. Pralidoxime is a biochemical antidote that reactivates acetylcholinesterase by removing OP from it. It is effective in treating both muscarinic and nicotinic symptoms. After some period of time, the acetylcholinesterase-OP compound undergoes a conformational change, known as aging, which renders the enzyme irreversibly resistant to reactivation by a pralidoxime. There has been a great deal of controversy over the effectiveness of pralidoxime in acute OP poisoning. However, it may be beneficial to administer pralidoxime for a sufficient period in case of severe poisoning with a large quantity of OP, which is common in Korea.

We report two cases of benign symmetrical lipornatosis, one associated with mild hyperthyroidism in a 57-year-old man and the other with alcoholic hepatitis in a 57-year-old man. In the histologic exsmination of the excised mass we found fibrous pseudocapsules surrounding adipose tissue in case 1, but not in case 2. Liposuction was performed in case 1 and simple excision in case 2 for treatment of tumors. The tumor masses were not recurred in clinical observation for follow-up 5 months after treatment.

As a study that the incision size was changed at each step of the surgical procedure but it is different, from the universal assumption that. the incision width initially created by a keratome during cataract extraction remained same size after the end of the surgical procedure, the authors investigated a comparative study between the two studies. We used specially designed instrument for accurate measuring of the incision size in 100 eyes and the incision size was measured after the creation of the initial incision, after the coirlpletion of phacoemulsification, after widening the incision and after the folded IOL insertion. Dividing group A and B in 50 eyes respectively, we designated the incision enlargement with 3.0mm keratome as A and 3.2mm keratome as B. It appeared statistically significant widening of the incision by approximately 0.06mm after the completion of phacoemulsification, 0.19mm after the folded IOL insertion in group A and 0. 05mm, 0.1mm in group B, respectively. Future studies of the surgical techniques and the postoperative healing after small incision cataract surgery must measure the actual incision size to avoid misleading assumption that the keratome size at the beginning of the procedure determines the incision size at. the end of the procedure.

OBJECTIVE: To report the pregnancy which was made by in vitro fertilization using recombinant follicle stimulating hormone and gonadotropin releasing hormone antagonist. MATERIAL AND METHOD: Case report. RESULTS: Six oocytes were retrieved and all were fertilized by intracytoplasmic sperm injection. Six embryos were transferred and the pregnancy was confirmed. CONCLUSION: It is envisaged that the availability of recombinant gonadotropins and gonadotropin releasing hormone antagonists will ultimately lead to shorter, cheaper and safer treatments, using reduced dosages.

Over a period of recent two years, 100 patients who had localized pulmonary lesions and underwent percutaneousneedle aspiration and biopsy, were analized. There were 56 malignancies and 44 benign and 79% respectively.Differentiation of malignancy vs. benignity was possible in 89% of cases obviating unnecessary exploratorythoracotomy for diagnostic purpose, Five cases were misinterpreted and eight cases were non-diagnostic oncytology. Inadequate materail was obtained in two cases; one was due to hardness of the mass, which, later,confirmed as chondrosarcoma, and the other was too samll(0.8x1.0cm) to be visible on lateral view. Theobainenability of the tissue was 98%. 14(14%) patients developed pneumothorax; one of them required treatment andthe reminder showed spontaneous resporption. (Transient neglibigle blood tinged sputum was found in 16(16%)cases.) The method, problems and complications are discussed. Authors recommend the percutaneous needle aspirationand biopsy as the initial procedure in diagnostic work-up of pulmonary coin lesions, especially when they aresmaller, more peripheral and metastatic neoplasm is neoplasm is suspected.
