The purpose of this study is to investigate the present state of worker's recognition and attitude about hazard materials and occupational disease in his workplace. In general worker's view of hazard materials and occupational disease that sis recognition and attitude is related to worker's health behavior for preventing occupational disease and improving his health status. The study subject is composed of workers in the asbestos related industry for example brake lining manufacturing industry, asbestos fiber manufacturing industry, and asbestos slate manufacturing industry. The result of the study are follows; 1. The most of workers in the asbestos related industry have taken health education and safety education, and the more than half of workers recognized the usefulness of preventive device, and ventilatory device in workplace. 2. About 70% of workers have always taken the preventive device. 3. About 80% of workers have recognized occupational disease in the asbestos related industry, and about 64% of workers have recognized that his workplace have harmful effect on his health. 4. Recognition about the usefulness of ventilatory device in work place has not related with any variables. But recognition about the usefulness of repiratory protector has related with recognition of hazard materials in his workplace, for example asbestos. 5. Attitude about severity and susceptability of occupational disease in the asbestos related industry have related with knowledge about hazard materials and occupational disease.

PURPOSE: One of the most common sites of recurrence after a curative resection of rectal cancer is the pelvis, and local control is a major goal of surgical treatment. The advantages of lateral pelvic lymph node dissection are regarded as questionable because lateral pelvic lymph node metastasis does not occur so frequently and because a lateral lymphadenectomy has a negative influence on the postoperative quality of life. The aim of this study was to clarify if lateral pelvic lymph node dissection (LPLD) conferred any benefit. METHODS: A total of 769 patients who underwent curative surgery for rectal cancer between 1981 and 2005 at the Department of Surgery, OOO Hospital, were reviewed retrospectively. One hundred ninety-three of these patients underwent a lateral pelvic lymph node dissection, and 576 patients had a total mesorectal excision with high ligation of the IMA. RESULTS: There was no difference in pathological characteristics between the two groups. Patients who underwent a lateral pelvic lymph node dissection had no statistically significant difference in terms of the 5-year survival rate at stage II and III (64% vs 65% at stage II, P=0.391; 49% vs 47% at stage III, P=0.815). CONCLUSIONS: A lateral pelvic lymph node dissection has no advantage as part of a standard operation for rectal cancer. A total mesorectal excision alone has good local control and survival compared with a lateral pelvic lymph node dissection.
