建物の用途や形態の制限に関する用途地域・容積率規定・高度地区等いわゆる地域地区制度は、大正8年以来、わが国の市街地土地利用計画制度の根幹をなしている制度である。この地域地区は、これまでに制度的改定に加えてその具体的運用である地域での指定の見直し改定が繰り返されてきた。本研究は、1968年に現都市計画法が新訂され、1973年の全面指定替え以降1981年に続く3回目の全面見直しであった1989年指定替えの実態を、実際的改定作業を担当した東京都の各区市の担当部局へのアンケート調査から分析したものである。基本地域が4種から8種になった1973年改定の実態と比較しつつ以下の点を分析・考察した。第ーに、土地利用計画の大枠を規定する東京都の指定の方針を比較分析すると、今回の方針が「整備の促進」を前提としつつも環境保全的基調から開発・再開発促進的基調に変換していること。第二に、実態的に改定内容を分析すると、結果的には大幅な改定となっている。その内容は規制の緩和の方向への見直しが基調で、用途規制の緩和のみならず、とくに指定容積率においては平均的に区部で9.5%、市部(19市)で6.9%の増加を見ていること。第三に、改定手続きとしては、審議会の運営は1973年以降定着しているが、地元説明会の開催やそれへの市民の参加状況、陳情等住民要望の状況を見ると、形式的には実施されているといえるものの実質的な住民参加は低調であったといえよう。Japan's first land use zoning regulation system was established in 1919,when the first modern town Planning Act and Building Standard Act were promulgated. With the revision of the Town Planning Act in 1968,the number of basic types of zones in the land zoning system increased from four to eight. In 1973,all the old land use control zones were canceled and newly designated. Since then,two major revisions of zone designation have taken place,in 1981 and 1989. It is of interest how the new land use regulation zones were designated,because the zoning regulation system is the most basic method for land use management and promotion of planned land use. Also,a new zoning regulation system is being prepared,with designation of new zones to be completed in several years. In the new system,the three existing residential zones are replaced with seven new ones. The quality of Tokyo's residential environment will be determined by how these new residential zones are designated,basically by whether deregulation or regularization,such as down-zoning,is implemented. This study investigates the course and circumstances of the 1989 zoning revision in comparison with the re-designation between 1973 and 1989. It contributes to the discussion on the management policy for the new zoning regulation system and the format of re-designation. We distributed questionnaires to all local government planning departments (on the level of ku-municipal borough and shi-city). Twenty-three ku-authorities(100%) and 19 shi-authorities (70%) returned the questionnaire that dealt with zoning regulation planning,zone proportion change,zoning draft plan,new designation plan,designation procedure (such as public hearings), public opinion surveys,composition and management of committees,etc. In contrast to the 1973 regularization,the 1989 land use control policy is based on deregulation of individual building construction and redevelopment. The basic assumption is that improvement of infrastructure must be promoted through cooperation between government and the private sector,but individual construction and develpment are deregulated. The existing land use regulation was largely revised in direction of deregulation of both land use control and building bulk ratios. Expecially,the new maximum bulk ratio permits an average ratio increase of 9.5% in inner Tokyo (ku-area) and 6.9% in outer Tokyo (shi-area). Finally,not only the number of public opinions collected but also the number of participants in the public hearings is lower than in 1973. One of reasons may be that many houses in inner Tokyo need to be rebuilt or renewed,because they were built about 30 years ago and thus are superannuated today. However,it is not easy to build a desirable house because of the small size of each site. Therefore,many owners hope for a relaxation of the building and bulk ratio regulations.

In this article, several important problems of threshold estimation in a Bayesian framework for nonlinear time series models are discussed. The paper starts with the issue of calculating the maximum likelihood and the Bayesian estimators for threshold autoregressive models. It turns out that the asymptotic efficiency of the Bayesian estimators in this type of singular estimation problems is superior than the maximum likelihood estimators. To illustrate the properties of these estimators and to explain the proposed method, the paper begins with the study of a linear threshold autoregressive model with i.i.d. Gaussian noise. The paper then extends the idea to other nonlinear and non-Gaussian models and illustrates the paradigm of limiting likelihood ratio, which is applicable to a much wider class of nonlinear models. The article also investigates the robustness issue and the possibility of restricting the observation window by narrow bands, which allows one to obtain asymptotically efficient estimators. Finally, the paper indicates how these results can be generalized from a TAR(1) model to a higher-order TAR(p) model with multiple thresholds. The paper concludes with a discussion of other related problems and illustrates the methodology by numerical simulations.

1992年4月と1997年10月の5年間における脳死と臓器移植に関する学生の意識の変化を明らかにするために、大学生を対象に調査を行った。臓器移植法について、その成立を肯定するものが多かった。しかし、実施については条件を整えてから実施すべきとの慎重論が強かった。「脳死は人の死」を認める者が少し多くなった。脳死の受容については、自分の場合は高くなったが、家族の場合は、受容できないとする者が高くなった。医者に対する信頼とインフォームド・コンセントについては、あまり大きな変化はみられなかった。本研究から、脳死・臓器移植への意思決定のためには、適切な情報の提供や総合的判断力の養成が必要であると示唆された。

A 30-year-old Vietnamese woman, about 19 weeks pregnant, was admitted for acute cerebral infarction with stenosis of the left middle cerebral artery (LMCA), tuberculous meningitis, and miliary tuberculosis. Treatment with heparin, quadruple anti-tuberculosis therapy, and dexamethasone afforded prompt symptomatic improvement. However, she delivered a stillbirth, after which there was recurrence of acute cerebral infarction with LMCA occlusion, sinus thrombosis, and cranial base inflammation. A thrice-weekly 100 mg dose of intrathecal isoniazid (INH) improved the signs of meningeal inflammation. The patient was discharged ambulatory after 7 months. In refractory tuberculous meningitis, multimodal therapy with intrathecal INH and steroids should be considered.

A 7-year-old Duroc sow exhibited emaciation, loss of appetite and rapid breathing, and was euthanized. Histopathological examination revealed mild to moderate fibrosis of the heart, cystic kidneys and ulcerative enteritis associated with Balantidium infection. Additionally, a small nodule was incidentally found in the peripancreatic fat tissue. The nodule consisted of disarranged cellular components: pancreatic islet cells (either insulin-, glucagon- or somatostatin-positive), pancreatic acinar cells, hepatocytes (human hepatocyte-positive) and ductal cells (cytokeratin 19-positive). Some of the human hepatocyte-positive cells were also positive for chromogranin A and cytokeratin 7, indicating that they were hepatic progenitor cells. The nodule was therefore diagnosed as hamartoma, probably originating from a fragment of the caudal verge of the liver bud, which contains hepatic and pancreatic progenitors.

The aim of this work was to present a novel minimally invasive surgical stabilization technique for canine atlanto-occipital dislocation and to report the associated magnetic resonance imaging (MRI) findings. All 5 dogs in this case series underwent 1.5 T MRI of the head and neck and 3 underwent both MRI and computed tomography (CT). Atlanto-occipital dislocations were diagnosed based on the increased joint space between the occipital condyles and the atlas on MRI. Surgery was performed immediately with a never previously described fixation technique based on an external ligature. The stabilization was performed via 4 holes drilled in the zygomatic processes and in the atlas wings on each side. A nylon monofilament of 1 mm diameter was inserted in the 4 holes, and an O-shaped ligature was carried out externally to the skin through the ipsilateral zygomatic arch. Ligatures were removed within 2 months. At the postsurgical follow-up examination, 14 days after surgery, all dogs were found to be ambulatory. Atlanto-occipital stability was assessed by clinical examination with an average of 24 months of follow-up. The positive outcomes in this case series suggest that atlanto-occipital dislocation may be surgically treated with this novel technique, irrespective of the severity of the clinical presentation and associated lesions observed on MRI.

Industrial waste generated in the domestic paper industry in Japan was 5.1 million tons in 2015, and after reduction and recycling, 152 thousand tons of the waste was consequently disposed. Organic sludge (paper sludge), which occupies two-thirds of the industrial waste generated in the paper industry, is incinerated for the purpose of volume reduction and thermal recycling, and then it becomes paper sludge ash (PS ash). PS ash is recycled as aggregate, roadbed material in the civil engineering field and cement raw material, but it is necessary to further expand the application and reduce the final disposal amount. From the above background, in this research, the strength characteristics, the durability performance and the environmental impact of low carbon concrete produced by reducing cement usage to 45% by using PS ash as admixture in addition to fly ash and blast furnace slag fine powder, were investigated. Experimental results show that the low carbon concrete produced in this research has long term strength development, and that PS ash does not contribute to long term strength. Moreover, the clay mineral contained in the PS ash has an effect of reducing drying shrinkage by water retention and expansion. With respect to durability performance, neutralization is promoted by decreasing the total cement amount, while salt tolerance resistance is improved. Frost damage resistance tends to decrease. The elution amount of toxic substances is less than the soil environmental standard value.

Acetabular dysplasia describes an underdeveloped or shallow, upwardly sloping acetabulum, which may occur with varying degrees of deformity of the proximal femur such as excessive femoral neck anteversion, coxa valga or femoral neck cam deformity. Numerous stabilising procedures have been described, one of the first being the shelf acetabuloplasty. Shelf procedure improves coverage of the femoral head, without changing orientation of the acetabulum.This will improve the range of movement in the hip and protect the femoral head. In this study, we investigated the effect of shelf acetabuloplasty for load distribution of acetabular roof and femoral head using the finite element method (FEM). A three-dimensional (3D) generic musculoskeletal model was developed based on computed tomographic (CT) to estimate joint reaction force. As a result, we funded load distribution decreased on the top of the ace tabular rim and femoral head. Shelf acetabuloplasty may effective procedure for acetabular dysplasia because of improvement for load distribution.

A frog shaped guiro is a wooden percussion instrument with an open-ended cave. By rubbing dorsal fins like saw blades on a back of the guiro with a wooden stick, the guiro generates the sound like a frog's voice. The exciting force, response acceleration and radiating sound pressure were measured with accelerometers on the stick and guiro and a condenser microphone and then the relation between the impulsively exciting force and sound pressure was revealed. A three-dimensional solid model of the guiro was built by use of an X-ray CT scanner device and a finite element model composed of tetrahedral elements was then obtained. The FEM modal analysis revealed that the frog shaped guiro had four dominant modes of vibration which was characterized by motion of mouth of the guiro such as the yawn mode and grinding teeth mode. The frequency spectrum of the sound pressure radiating from the frog shaped guiro excited by sequential impulsive forces moving along the dorsal fins was theoretically estimated. Since the estimated sound pressure agreed well with the measured one, the sound radiating from the guiro like a frog's voice could be reproduced. It was also revealed that the variation of driving point mobility of the dorsal fins and amplitude of the exciting force affected to generate the sound like a frog's voice.
