In order to improve the mechanical properties of sintered low alloy steels, Fe-1.5%Si-2.0%Ni-(0.5%Mo)-0.1-0.5%C compacts sintered at 1250°C for 3.6 ks were cooled in various conditions after the ... solution treatment at 960°C. The structures of specimens were controlled by changing the cooling rate. The relation between the structures which transformed during continuous cooling and the mechanical properties was studied. The results are summarized as follows: On the continuous cooling transformation diagram, the addition of molybdenum shifted the ferrite and pearlite noses to longer time and enlarged the sections of bainitic and martensitic transformations. It was necessary, under the optimum carbon content and cooling rate, to get the fine mixed structure of polygonal ferrite, bainitic ferrite and upper bainite which resulted in good combination of strength, ductility and toughness. But lower bainite and martensite appeared constantly in the structure of the specimens cooled in uniform cooling rate and decreased the ductility and toughness. The STEP cooling, which was the treatment of changing the cooling rate at 600°C, lead the fine mixed structure mentioned above containing 1025 vol% retained austenite. The STEP cooled specimens showed good mechanical properties; for example in 0.3-0.4%C specimen, 750 MPa of tensile strength, 8% of elongation and 120 kJ/m2 of Charpy impact value. več

This paper aims to propose evaluation methods of public transport services in depopulated areas. A quality of life index, a customer satisfaction index and an equality index are proposed to evaluate ... transit services which include Demand Responsive Transit (DRT). A total of four questionnaire surveys were carried out in rural areas in Shimane prefecture. The effect of a new DRT service is obtained using co-variance structure analysis. QOL and CS indices are calculated using the ordered probit model. Evaluation indices which include not only the profitability of an alternative are necessary when planning the introduction or improvement of a transit service in depopulated areas where operating a transit service is unprofitable. več

観光地においては、地域住民の生活空間と観光客の交通が密接に関わってくることが多い。そのため、住民が地域振興のために「観光客の賑わい」を希求する一方で、そのための施策により「日常生活の利便性」が低下することは許容し難く感じることも多く、この両者のトレードオフから地域の合意形成が困難となる場合も多々見られる。観光地における地域住民の合意形成を得、「観光客による賑わい」と「日常生活の利便性」が折り合う道路を構築するためには、まず地域住民が観光地の道路のあり方、役割をどのように捉えているのかの検討が重要となってくる。本研究では、地域住民の意識に着目し、観光地における地域住民の道路に対する意識を検討した。出雲大社門前の参道である神門通り周辺の居住者への意識調査から、観光地の道路において重要視されている道路の機能・役割は観光地としての賑わいであることが明らかになった。また、それら意識は三つのタイプに分類され、意識の違いによって交通社会実験の評価やみちづくりに対する考え方に大きく影響を及ぼしてくるということが明らかになった。

The author carried out a study on 549 necropsy cases without primary disease of pancreas (tumor, inflammation, hemorrhage, necrosis, diabetes mellitus) between the years 1962 and 1969. This survey ... consisted primarily of pathological examination of principal athological-anato -mical changes, fibrous increase was observed in 400 cases (73%) . Fibrous increase of the pancreas was classified morphologically into 3 types ; 1) intralo-bar type (247 cases), 2) interlobar type (59 cases), 3) mixed type (94 cases) . They were also histogenetically devided into the following three types ; 1) periductal type (297 cases) . 2) perivascular type (7 cases), 3) mixed type (96 cases) . Fibrous increase in the pancreas originated with replacement of the residual necrosis owing to various generalized disorders, particularly of neighbouring tissues and viscerae. This fibrous tissue increases progressively and irreversively. več

本研究は，過疎地域における公共交通サービスの評価手法としてQOL（生活の質）指標，CS（顧客満足度）指標，EQ（平等性）指標を提案する．まず，島根県の過疎地域で運行されているDRTサービスについて，共分散構造分析を適用してそのQOLに及ぼす効果を明らかにしている．次に，集落の生活のしやすさの満足度をQOL，交通サービスの総合的な満足度をCS指標として，オーダードプロビットモデルで分析する．また，EQ指標はGISを活用して，設定したサービス水準の平等性を表現する．過疎地域の公共交通計画では，このような採算性以外の評価指標が重要となる．

Recently two autopsy cases of chronic pancreatitis were experienced. Case 1. 61yrs. female. Pathological diagnosis was chronic relapsing pancreatitis. Case 2. 74yrs. male. Pathological diagnosis was ... esophageal cancer (second contractive portion, squamous cell carcinoma) and chronic pancreatitis with pancreatolithiasis. več

A case of cylindroma of the hard palate metastasizing to the lungs in a seventy nine years old man is described with clinical and postmortem findings. Some of hard palate tumors are also reviewed ... literaturely. Invasion to the perineural space and involvement of regional lymph nodes of tumor cells are not revealed. The survival time of this case is five years after plumonary metastasis was found. več
