From March of 1979 through December of 1982, 84 patients with supraglottic carcinoma were seen and evaluated in the Department of Therapeutic Radiology, Seoul National University Hospital. Of these, 58 patients were treated with a curative intent by employing either radiotherapy alone or a combined approach of radiotherapy plus surgery. Sixteen patients refused to complete the treatment program. Seventy-three per cent of patients had T3 and T4 lesions and 63% of patients had lymph node metastasis at the time of diagnosis. Actuarial recurrence-free survival at 3 year was : Stage Ⅰ~Ⅱ 62%, Stage Ⅲ 54%, Stage Ⅳ 18%. For T1-2, T3 and T4 lesions, the actuarial recurrence free survival at 3 years were 50%, 34% and 9% respectively. Of 39 patients with treatment failure, 29 patients (78%) had uncontrol or ultimate recurrence at the primary site while 9 patients having lymph node recurrence, 14 patients(21%) had lymph node recurrence, and 5 patients had distant metastasis. It is suggested that planned combined radiotherapy is indicated for advanced but resectable supraglottic carcinoma.

2×10^(18)ions/㎠의 산소이온이 180keV로 주입된 실리콘웨어퍼를 1250℃에서 6시간 동안 질소분위기로 열처리하여 SIMOX SOI 구조를 제조하였다. 이온주업 후 열처리 과정에서 산소원자의 거동을 AES와 TEM으로 분석하였고, SRP법으로 시료의 전기적 특성을 조사였다. 그 결과 고온의 열처리 후에 SOI층 내에 산소석출물이 존재하고 있음을 관찰할 수 있었으며 이들은 SOI층의 전기적 특성에 심각한 영향을 미침을 알았다. 그리고 열처리과정에서 SOI층 내 산소농도의 감소는 이들 석출물의 성장소멸기구에 지배됨을 알았다. SIMOX SOI structures were formed by oxygen ion implantation with a dose of 2×10^(18) ions/㎠ at 180 keV and post-implantation annealing at 1250℃ for 6 hours in nitrogen ambient. The oxygen redistribution process during post-implantation annealing was examined by AES and TEM. The electrical property of the structure was investigated by SRP method. We could find oxygen precipitates in SOI layer after high temperature annealing. The influence of the precipitates to the electrical property of the SOI layer was discussed. And the limiting factor to the decrease of the precipitates during post-implantation annealing was discussed also.

To study the effects of exposure to carbon disulfide on blood pressure and serum cholesterol level, we gathered the informations from file of the periodic health examination for occupational disease, the periodic health examination for general disease and medical records in, Wonjin factory clinic. The study subjects were 266 workers who had worked in spinning department as exposure group, and 207 male office workers and 59 female office workers as non-exposure group. The results are as follows; 1. The slope coefficients of systolic blood pressure(as dependent variable) and age and exposure duration(as independent variable) were 0.013 and 0.066 respectively in exposure group. And the slope coefficients of diastolic blood pressure(as dependent variable) and age and expoure duration(as independent variable) mere 0.010 and 0.051 respectively in expoure group. 2. The slope coefficients of systolic blood pressure(as dependent variable) and age and tenure duration(as independent variable) were 0.019 and 0.009 respectively in male unexposure group, and were 0.032 and 0.018 respectively in female unexposure group. And the slope coefficients of diastolic blood pressure(as dependent variable) and age and tenure duration(as independent variable) were 0.016 and 0.009 respectively in male unexposure group, and were 0.019 and 0.033 respectively in female unexposure group. 3. The slope coefficient of exposure duration was greater than that of age in exposure group and that of age was greater than that of tenure duration in male unexposure group. 4.There was no significant difference of blood pressure between the exposure and non-exposure group. 5.The slope coefficients of Serum cholesterol(as dependent variable) and age and exposure duration(as independent variable) were 0.03 and 0.035 respectively in exposure group. The slope coefficients of serum cholesterol(as dependent variable) and age and tenure duration(as independent variable) were 0.102 and -0.012 respectively in male unexposure group. And the slope coefficients was very low in female unexposure group. 6. The slope coefficient of exposure duration was similar to that of age in exposure group, and only age was positively related to serum cholesterol in male unexposure group.
