Higashiyama Park in old Taiza Town in the Tango region of Kyoto Prefecture is a private park built by Genzo Tani in the Taisho-Early Showa period. This study clarifies the establishment process,design and way of use of Higashiyama Park which was when the urban park system was established by landscape architecture. As a result of document analysis, Higashiyama park was made as a contribution to the local community where Tani was born. Parks have been selected as a way of contributing to the public, and were considered as recreational places for increasing public health. The Japanese garden style was adapted to Higashiyama Park, although Tani knew of modern urban parks in other areas of Kyoto and Osaka. The park concept was affected by Maruyama Park (Kyoto) derived from pre-modern scenic places. In his idea, establishment of the park was not a purpose but a mean of contribution to his birthplace. Hence, usage was important requirements for Higashiyama Park and the restaurant of the park were considered as appropriate to urban parks. Tani offered a recreational place, however, Higashiyama park is no longer existence now by the snow disaster on 1963 after Tani was dead.

Dense suspension of non-Brownian particles such as potato starch often shows counter-intuitive behaviors due to its discontinuous rheological property. Using this particular rheological property, people can run on a dense suspension. However, once the motion of leg becomes too slow, the leg is arrested, namely, it is difficult to walk on the surface. To explain this peculiar behavior, propagation of jamming front caused by an impact onto a dense suspension has been considered recently. The effectively solidified zone is developed by the jamming-front propagation. This solidified zone effectively increases viscosity of the suspension. In addition, when the jamming front reaches the bottom of the container, a solidified pillar which causes effective elasticity is developed. Because the lifetime of the solidified zone is short, the suspension recovers usual viscosity after a while. To characterize the viscoelastic properties of the impacted dense suspension, a set of simple impact experiments was performed. A solid sphere was dropped from a certain height onto a suspension. The impact and rebound dynamics were recorded by a high-speed camera. Using the kinematic data, viscoelasticity of the impacted suspension was measured. The obtained data are consistent with the idea of jamming-front propagation. In addition to the impact onto a static target, impact experiments onto a dense suspension under the influence of mechanical vibration were also performed. Although the mechanical vibration can significantly deform the free surface of suspension, the impact response was hardly affected. In this article, a brief review of the impact-induced jamming-front propagation and the resultant effective viscoelasticity is presented.

シュウ酸カルシウムを硫酸で分解してシュウ酸と硫酸カルシウムを生成させる場合,生成したシュウ酸がさらに硫酸により分解を受け,ギ酸と炭酸ガス,さらに一酸化炭素,炭酸ガス,水に分解する可能性がある。著者はシュウ酸を種々の濃度および温度の硫酸中で加熱し,シュウ酸の分解量を測定した。この結果,分解条件60℃,80℃,90℃各1時間においてシュウ酸が分解を起こす硫酸の最低濃度はそれぞれ91%,84%,75%であると推定した。分解温度50~100℃,硫酸濃度60~100%の範囲においては,温度T(℃),硫酸濃度C(%),分解率F(%)との間にはF=exp[-86.6+0.511C+0.996T-0.0095CT+0.00362C2]の関係式が近似的に成立つことを知った。

This paper reviews the statistical aspects in pharmacokinetic analysis of clinical Phase 1 trials. Based on the understanding that most pharmacokinetic parameters follow a lognormal distribution, it is considered to be appropriate to summarize them by the geometric mean, geometric CV or geometric SD. Then we conducted simulation studies of a pharmacokinetic model to investigate whether pharmacokinetic parameters follow a lognormal distribution. Using numerical examples obtained by the simulation, we described in detail how to display the summary statistics of pharmacokinetic parameters. We also indicated that geometric mean is also useful to summarize the plasma concentration, and that the concetration below the lower limit of quantification shoud be carefully handled.

In this paper, I intend to present a genealogy as to how crimes by mentally disordered people came to be recognized as a problem to be dealt with by special legal treatments, i. e. security measures. Though the security measures have never been realized in Japan, their introduction have been argued as early as the Taisho era. Considering the history of this argument, “mentally disordered criminals” were not considered a problem because they were dangerous. Rather, it was felt that they were made “dangerous and irresponsible” subjects due to the debate concerning the security measures themselves.

One characteristic of Mahayana bodhisattva precepts is the idea of “self-ordination”. In the case where one has no teacher, self ordination means vowing to keep the Buddhist precepts personally. Although in self ordination the spiritual aspect is stressed, there also need to be certain conditions for it to take place. This characteristic is explained in the idea of “visionary experience”, found in the 23rd precept of the Fanwang jing. This essay examines the influence of selfordination as found in the Fanwang jing, taking into account the Huayan jing and the point of view of practice.Visionary experience is built up through practice. In this way, the visionary experience is based on practice, and the person who completes “self ordination” follows the influence of the Huayan jing in the Fanwang jing, hence bodhisattva non-regression is necessary for visionary experience. The disciple of the Buddha is penitent, practices and sees the visionary experience as proof of ordination. Accordingly, the visionary experience found in “self ordination” of the Fanwang jing should be understood from the point of view of practice.

The aim of this paper is to clarify the relationship between reclamation work in Karafuto (present-day Sakhalin) and the construction of its capital city, Toyohara (present-day Yuzhno-Sakhalinsk) after the Russo-Japanese war. There are four main points of consideration. As a study of colonization, this paper examines the relationship between suzerain policy and urban design as well as the transfer of systems and techniques from domestic to overseas territories. In addition, since Karafuto resembled Hokkaido in regional character during Japanese colonial times, as a study of urban design this paper compares Karafuto with Hokkaido, especially in terms of the intentional construction and nodal function of cities. Based on these four points, the contents of this paper can be summarized as follows:1. Similar to Hokkaido in its population density and ethnic composition, Karafuto has been considered the Japanese overseas territory most similar to its domestic territory in terms of colonial government policies. It has not always been considered so similar in regard to climate and agriculture, however, leading the author to surmize a feeling of incongruity among its settlers. As the ratio of non-settling fishermen to permanent settlers was high in the early colonial times, the encouragement of permanent residence was the most important task of the reclamation work.2. The construction of the new capital city was begun shortly after the Japanese occupation of Karafuto. From among several choices, the village of Urajimirofuka was selected as the site for the new city due to its location in the Suzuya Plain, an important agricultural area, yet also near a military base and along the main road. The new capital city was named Toyohara.3. Greatly influenced by the division of farmland, the streets of the new city were laid out in a grid pattern, modeled after the one used in Sapporo. The center line of the new town was its railway, later dividing the governmental area from the civil area. If the design of Sapporo was greatly influenced by the design of cities in domestic territories, then the planning technology of Toyohara can be considered to have been introduced into Karafuto from Japanese domestic territories by way of Hokkaido.4. The construction of Toyohara was closely related to the division work of farmland. The plans for Toyohara were drafted mainly by persons associated with Sapporo Agricultural College. That is to say, Karafuto received a transfer of experience and technology from the reclamation work carried out in settling Hokkaido as a domestic colony.5. In the early days of Japanese colonization, the nodal function of cities on Karafuto was of the Reverse Y type, concentrating every function in the city of Otomari. After Toyohara was constructed, the function changed to a Sideways T type, with everything concentrated there. The change was almost complete by 1911.6. The inland settlement of Karafuto was more difficult than had been expected. As Toyohara was not enthusiastically received by settlers, the Japanese colonial government in Karafuto had to politically promote the invitation of settlers and encourage their permanent residence. Although a few cities and fishing villages developed along coastal areas, few permanent settlements developed further inland.

近年、モアレ立体の原理を用いた立体表示が提案されている。従来のモアレを利用した表示装置では、表示物自体ではなく、表示装置の背景部分に奥行きを持たせることで、表示物に相対的な奥行きを与えていた。そこで、本論文では、表示物自体が実際の奥行きを持ったモアレ式の立体表示を実現することを目的とし、市販の液晶ディスプレイとレンチキュラーレンズを用いたモアレ式立体ディスプレイを提案する。試作した装置を用いた実験では、液晶ディスプレイに表示した周期パターンとレンチキュラーレンズによるモアレ干渉で、奥行きをもった画像の表示が可能であることが確認できた。

Stratospheric aerosols over the high Arctic at Ny Ålesund, Svalbard (79°N, 12°E) were observed continuously for four years from March 2014 by a lidar system using the second harmonic wavelength (532 nm) of the Nd:YAG laser. Our observations reveal the seasonal features of stratospheric aerosols and the arrival of the smoke at the high Arctic from Canadian forest-fire in August 2017. We estimated the seasonal variation for three years before the Canadian forest-fire when there was no apparent volcanic effect. In the estimation, we removed polar stratospheric clouds by the threshold temperature of their formation. The seasonal variation for the three years is that the vertical profiles of the backscattering ratio take a maximum value of about 1.05-1.06 at altitudes between 13 and 16 km from December to March, and about 1.02-1.04 at altitudes between 17 and 20 km from April to November. These results are compared with the results observed at the low Arctic, northern Norway. We also present the increases in the backscattering ratio and the volume depolarization ratio from September to December 2017 caused by the smoke from the Canadian forest-fire.

While global warming may expand suitable places for potato cultivation in cold regions, it may reduce the yield due to the increase of hot days during the tuber growth period. This study evaluated the effects of global warming on potato cultivation over Hokkaido by dynamically-downscaled ensemble experiments called d4PDF and assessed applicability of possible adaptive measures. In this study, we define the suitable area based on the accumulated temperature and deduced a relationship between the potato yield per unit area and the number of hot days (maximum temperature > 28°C) from crop statistic data. In a warming environment with 2K or 4K increase in global-mean temperature relative to the present climate (1981-2010), the accumulated temperatures likely satisfied the criterion on potato production almost over Hokkaido. The risk of growth delay due to cold weather was projected to reduce. However, hot days in the tuber growth period would increase, reducing potato yield by 7% in a plus 2-K climate and 16% in a plus 4-K climate. This risk of yield loss would not be avoidable by moving up planting by 30 days, and the development of varieties that are tolerant to 31-33°C would be a possible way to adaptation.

Relationship between diurnal convection and the intraseasonal oscillation (ISO) over the western Maritime Continent (MC) was investigated by a case study of an ISO event that occurred during the Years of the Maritime Continent (YMC)-Sumatra 2017 campaign. Two sets of global cloud-permitting simulations using cloud microphysics settings for ISO prediction (CTL) and for climate simulation (MOD) were performed to clarify their impacts. CTL had biases of weaker diurnal variation and smaller precipitation amounts over land than in observations; these were reduced in MOD by higher probabilities of local intense convection in the middle troposphere and higher precipitation efficiency. The enhanced convection over land coincided with suppressed convection over the surrounding ocean, especially at the diurnal peak time of land convection. Exception is the onset period of the ISO convection, when upward moisture advection and precipitation increased also over ocean in MOD than in CTL at the diurnal peak time of oceanic convection. These results suggest that the enhancement of local convection over the MC by the cloud microphysical processes basically hinders the ISO convection by the activation of land convection, but it also favors the ISO convection development over ocean during the onset period.

Climate change impact assessment studies often use future projections of only a few global climate models (GCMs) due to limited research resources. Here we develop a novel method to select a small subset of GCMs that widely capture the uncertainty range of large ensemble. By applying this method, we select a subset of five GCM projections from the Coupled Model Intercomparison Project Phase 6 (CMIP6) ensemble for impact and adaptation studies in Japan. At first, we omit GCMs whose global warming projections have been evaluated to be overestimated in the recent literature. Then, we select a subset of five GCMs that widely captures the uncertainty ranges for 8 climate variables and have good performances in present-climate simulations. These selected GCM simulations will be used to provide better climate scenarios for impact and adaptation studies than those in the previous impact assessment project.

Failures on demand of a reactor core isolation cooling (RCIC) system in BWRs are the most frequent events of limiting conditions for operation during 1982-2006 in Japan, according to data gathered in Nuclear Information Archives (NUCIA). In this work, probabilities of failures of the RCIC system are analyzed by using the hierarchical Bayes method. The failures on demand of the RCIC system are classified into two groups; one is related to the demand at a periodical inspection test, which is performed almost every 13 months at the end of the periodical inspection of the nuclear power plant, and the other is related to the monthly surveillance test during plant operation. The hierarchical Bayes analysis shows the characteristics of probabilities of failures of each Japanese plant and also that probabilities of failures at the periodical inspection test are quite different from those at the surveillance test, comparing Japanese nuclear power plants with American ones. This paper provides a new approach to analyzing sparse failure data taken from nuclear power plants in Japan.

Neutron spectrum unfolding is a widely used technique for characterizing neutron fields for various types of reactor dosimetry, where the neutron spectrum is derived from integral measured data such as multiple-foil activation rates and moderated neutron detector counts. Many spectrum unfolding codes have been developed so far and their performances have been compared. However, a standardized metrology for neutron spectrum unfolding has not been satisfactorily established yet from the viewpoints of adequate selection and usage of unfolding codes, response function database and input data set preparation. This article reviews the present status of the neutron spectrum unfolding technique that is mainly related to reactor dosimetry with activation foils and discusses the validity of the solution spectra obtained from different unfolding codes under a typical fast reactor neutron field. The results show that the solution spectrum strongly depends on a priori (i.e., guess) spectrum required for the input data as well as the theoretical assumption in each unfolding code. The issues that must be resolved to improve the accuracy of reactor dosimetry are summarized for the a priori input spectrum, the nuclear database, and the standardization of the unfolding procedure.
