Slide burnishing process, which is a surface severe plastic deformation technique, offers an attractive post-machining alternative due to its chip-less and relatively simple operations. The purpose of the present work is to investigate effects of initial turned surface roughness on the burnished surface roughness and hardness in slide burnishing. The carbon steel samples those have different roughness surfaces being treated were prepared by turning by varying the feed. Slide burnishing was then carried out by a silicon nitride ceramic ball that was loaded and fed on the turned surface of a rotating specimen using a lathe machine. It was found that the turned surfaces were smoothed drastically by the burnishing process, and that the Ra and Rz values were reduced at most by a factor of 52 and 21, respectively. However, the smoothing effect of burnishing has limit, and the limited maximum height roughness (Rz*) for burnishing smoothing increased under a higher burnishing force and with a larger ball diameter. When the Rz values of initial turned surfaces were less than the Rz*, the roughness of the burnished surfaces did not depend on the roughness of the initial turned surface and the burnishing force. There was no significant difference in the burnished microstructure and hardness under a specific burnishing force among the initial turned surface roughness, while a higher burnishing force caused a greater increase in surface hardness.

An 80-year-old male was admitted to our hospital because of near-drowning in a hot spring. Besides hypoxia, serum calcium was extremely high at 15.5 mg/dL on admission. After the treatment with normal saline infusion, furosemide and calcitonin, the hypercalcemia was transient and didn’t recur during the course. The hot spring water contained much calcium, so his hypercalcemia was considered to be a result of calcium absorption mainly through the alveoli. In this case, we revealed that serum calcium rose within a short time after drowning, suggesting the necessity to measure the calcium concentration of the drowning fluid in a near-drowning victim.

Salivary gland tumors represent 2% - 6.5% of all head and neck tumors. Since salivary gland tumors have various clinical features and histological types, it is often difficult to diagnose and treat them. The aim of this study was to conduct a retrospective clinical-statistical analysis of 37 minor salivary gland tumors (MSGTs) treated in the Department of Oral Surgery at Nihon University School of Dentistry at Matsudo over a 16-year period. The frequencies and distributions of sex, age, occurrence site, preoperative examination (fine needle cytology and/or biopsy), treatment, and prognosis of the tumors were analyzed and compared with previous reports. The average age at diagnosis was 58.1 years (range 22 - 91 years). The peak occurrence of tumors was in the sixties (10 cases, 27.0%), followed by the forties (8 cases, 21.6%) and the seventies (7 cases, 18.9%). The average age of patients with benign tumors was 56.8 years (range 22 - 91 years). For malignant tumors, the average age was 61.7 years (range 42 - 81 years). The male-female ratio was 1:2.1 for all minor salivary gland tumors, 1:2.4 for benign tumors, and 1.5:1 for malignant tumors. There were 27 (73.0%) benign and 10 (27.0%) malignant tumors. Pleomorphic adenoma (PA) was the most common tumor (24 (64.9%) cases). Most salivary gland tumors originated from the palate (21 cases, 56.8%);the second most common site was the buccal mucosa (14 cases, 37.8%). For most patients, an intraoral mass was the primary presentation, and the second most common symptom was swelling. Surgical treatment was performed for all cases, both benign and malignant tumors. There was one case of local recurrence of PA, as well as one of multiple lung metastases after surgery for adenoid cystic carcinoma. Diagnosis and treatment of MSGTs are often delayed because the patients have few symptoms, and it is difficult to distinguish benign from malignant tumors. More cases need to be examined in the future, and the diagnostic accuracy of im

本文以东京大学为例,概览了1877年至今的日本建筑教育史。东京大学创建初期的结构、设计、历史三足鼎立的格局自1914年始渐呈强化工程技术教育倾向。1950年代诞生的"建筑计划学",促成日本建筑设计强调科学依据的特色。为了弥补1962年丹下健三及其梯队离开建筑学科而导致设计教学的弱化,1970年代开始采取明星建筑师执教建筑设计课的方式,并延续至今。至1920年代为止日本开设建筑教育的各大学,仅一所例外,其余院校的创始人全部来自东京大学。且以辰野金吾创建日本建筑学会为首,东京大学各专业教授创建了本专业的全国性学会。由于东京大学在教育及学会体制的全方位影响,其强调工学教育以及注重科学性、体系化的特征也成为日本全国建筑教育的普遍特征。
