Backgroud and Objectives: Major salivary gland tumor is a rare disease with a largely unknown origin. And also corresponding to the diversity of histopathologic characteristics is an equally wide distribution of clinical behavior that makes treatment decisions difficult. The aim of this study is to analysis the clinical experience of our major salivary gland tumor and to suggest a guidline of management. Materials and Methods : We studied clinical manifestations and treatment results of 104 patients who were diagnosed as major salivary gland tumors. Tumor site, patient age and sex of the patients were analysed. Histopathologic diagnosis, treatment modality, lymph nodes metastasis, recurrence rate and 5-year survival rate were studied on malignant tumors. Results: 1) 48 patients were male and 56 patients were female. 2) Benign tumors were 79 cases. They consisted of 57 cases(72%) of parotid tumor, 22 cases(27%) of submandibular tumor. And pleomorphic adenoma was the most common benign tumor. 3) Malignant tumors were 25 cases and were consisted of 19 cases(76%) of parotid tumor, 4 cases(l6%) of submandibular tumor and 2 cases(8%) of sublingual gland tumor with high-grade mucoepidermoid carcinoma as the most common cause. 4) In the malignant tumors, the number of stage I, II tumors was 14 and that of stage III, IV tumors was 11. Neck node metastasis was noted in 8 cases. 5) 8 cases of malignant tumor were died and all of them had high-grade malignancy. And they were dead before 17 months from the time of diagnosis. 6) Mean survival duration in the malignant salivary gland tumor was 56 months. 7) High-grade malignancy had a 5-year survival rate of 57.9%. A 5-year survival rate of TI, T2 patients was 92.9% and that of T3, T4 patients was 36.4%. That of patients who had neck node metastasis was 37.5% and that of those who had tree neck was 82.4%. Conclusion: The results of this study suggest that the survival rate is dependent on the tumor size, lymph node matastasis and histologic grade. And also the early diagnosis and radical surgery result in the increased survival rate and are effective for prevention of the tumor recurrance.

The KASINICS (Korea Astronomy and Space science Institute Near Infrared Camera System) is a ground-based near-infrared (NIR) imaging instrument. KASINICS has offner relay optics to reduce unwanted infrared light. For the offner optics, we adopted an ultra precision machining process which is installed at KBSI (Korea Basics Science research Institute). Since the offner relay optics is made of aluminum 6061 metal material, we did several tests to reach the specification. We found that a 0.497mm radius nose bite and 220m/min machining speed are best tool and condition to make this offner optics with the precision machine. In this paper, we report the technical method of ultra precision machining and results of the KASINICS offner optics.

This study aims to find the optimal cutting conditions, when are IR Detection device HgCdTe is machined with diamond tool of diamond turning machine. Machining technique for HgCdTe with single point diamond turning tool is reported in this paper. The main factors influencing the machined surface quality are discovered and regularities of machining process are drawn. It has been found HgCdTe has more and more important applications in the field of modern optics. The purpose of our research is to find the optimum machining conditions for ductile cutting of HgCdTe and apply the SPDT technique to the manufacturing of ultra precision optical components of brittle materials.

저자들은 1985년부터 1992년까지 연세대학교 의과대학 영동세브란스병원에서 치료한 병기 T₁성문암 환자 30례를 대상으로 임상적 분석을 시행하여 다음과 같은 결과를 얻었다. 1) 병기 T₁성문암의 경우 남여의 비는 29:1로 남자가 대부분이었으며, 60대에 호발하였다. 2) 전례가 편평상피암이었으며 조직학적 분화도가 좋았던 경우가 13례, 중간 분화도이었던 경우가 17례이었다. 3) 초치료로 방사선치료를 한 경우 25.9%에서 재발이 있었으며, 부분후두적출술을 시행한 2례중 1례에서 재발이 있었다. 4) 재발한 경우, 전례에서, 원발부위의 재발이었고 경부재발이 동반된 경우가 1례있었으며, 1년이내 재발이 흔하였다. 5)원발부위 재발의 경우 전연합(anterior commissure)에서 재발이 빈발하였다. 6) 5년 생존율은 81.5%로 이는 병기간, 병리조직학적으로 유의한 차이는 없었다. Laryngeal cancer is one of the most frequent cancers in the head and neck area. Clinical analysis was performed on 30 cases of treated T₁ glottic cancer patients. Early glottic cancer occured most frequently in male in their sixties and all were well or moderately well differentiated squamous cell carcinoma. Overall five year survival rate was 81.5% and there was no significant difference between stages or the differentiation of the diseases. Recurrence at the primary site, especially anterior commissure, was common, thus careful pre- and postoperative follow up evaluation is recommended.
