丸山薫とリルケ : 『物象詩集』の方法
No full textAlthough he was one of the representative poets of the Showa Era (1925-1989), Maruyama Kaoru has not fully attracted researchers' attention. He established a unique poetic world by "Bussho Shishu", the collection of poems of his own selection, published in 1941. He stated that his motivation to compose poems was rooted in "a tantalizing desire for objects and nostalgic emotions to them". The author assumes his method of introducing feelings into objects derived from Rainer Maria Rilke. Hori Tatsuo and Tachihara Michizo have often been regarded as the Japanese poets most strongly influenced by Rilke. In this paper, the author attempts to make clear that Maruyama Kaoru also cultivated his new lyric style under the influence of Rilke, focusing on his "Horui" and "Mizu no Kokoro".海老井英次教授退官記念号〈Special Issue〉dedicated to Professor EBII Eij
Raising the Quality of Secondary Education in East Asia
No full textThe author seeks to broaden our
understanding of the determinants of student achievement
among East Asian economies using the TIMSS-R data set and,
in the process, to remedy some of the ambiguities in the
literature to date. These ambiguities are frequently due to
the sparseness of detailed data on students, teachers, and
schools. The TIMSS-R data set offers detailed information on
these variables, which is not typically available from other
sources, allowing the author to isolate the impact of
various factors affecting student achievement, while
controlling for specific characteristics of the students,
teachers, and schools surveyed. The results indicate that
the most consistent factors affecting student performance
are characteristics associated with students (innate
abilities and home resources). Moreover, the author does not
find any consistent relationship between the performance of
students and school resources or teacher autonomy, both of
which are often advocated in the discussion of education reform
SAND AND SILTY-SAND SOIL STABILIZATION USING BACTERIAL ENZYME INDUCED CALCITE PRECIPITATION (BEICP)
No full textThis paper examines the bio-derived stabilization of sand-only or sand-plus-silt soils using an extracted bacterial enzyme application to achieve induced calcite precipitation (ICP). As compared to conventional microbial induced calcite precipitation (MICP) methods, which use intact bacterial cells, this strategy which uses free urease catalysts to secure bacterial enzyme induced calcite precipitation (BEICP) appears to offer an improved means of biostabilizing silty-sand soils as compared to that of MICP processing. Several benefits may possibly be achieved with this BEICP approach, including bio-safety, environmental, and geotechnical improvements. Notably, the BEICP biostabilization results presented by this paper demonstrate: 1) higher rates of catalytic urease activity, 2) a wider range of application with sand-plus-silt soil applications bearing low plasticity properties, and 3) the ability to retain higher levels of soil permeability after BEICP processing. Comparative BEICP versus MICP results for sand-only systems are presented, along with BEICP-based results for stabilized soil mixtures at 90-10 and 80-20 percentile sand-silt ratios. This BEICP methodâ s ability to obtain unconfined compressive strength (UCS) results in excess of 1,000 kPa with sand-plus-silt soil mixtures is particularly noteworthy.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Author response
No full textDevelopmental potentials of cells are tightly controlled at multiple levels. The embryonic Drosophila airway tree is roughly subdivided into two types of cells with distinct developmental potentials: a proximally located group of multipotent adult precursor cells (P-fate) and a distally located population of more differentiated cells (D-fate). We show that the GATA-family transcription factor (TF) Grain promotes the P-fate and the POU-homeobox TF Ventral veinless (Vvl/Drifter/U-turned) stimulates the D-fate. Hedgehog and receptor tyrosine kinase (RTK) signaling cooperate with Vvl to drive the D-fate at the expense of the P-fate while negative regulators of either of these signaling pathways ensure P-fate specification. Local concentrations of Decapentaplegic/BMP, Wingless/Wnt, and Hedgehog signals differentially regulate the expression of D-factors and P-factors to transform an equipotent primordial field into a concentric pattern of radially different morphogenetic potentials, which gradually gives rise to the distal-proximal organization of distinct cell types in the mature airway.</p
Supplemental Study in the System of Taxes on Merchants in the Sung 宋 Dynasty
No full textThe late Dr. Shigeshi Kato has already described in outline the system of taxes on merchants in the Sung dynasty, but the details of the system remain unclear. The author has here attempted to discover the details by investigating some of the aspects of the system: the organization of the tax-collecting posts (shui-wu (稅務)), the routes of tax-collecting, the relation between the amount of the taxes and the revenue of the dynasty, some difficulties caused by tax-collecting, and the taxes on special goods. Through the above method, he concludes that in the Sung dynasty goods were circulated all through, the country by the merchants. The prosperity of K'ai-feng (開封) or Hang-chou (杭州) was brought about by the development of these merchants' business. The funds collected from the shui-wu established throughout the country began to occupy an important part of the dynasty's revenue from the Sung dynasty. The importance which commercial business had in the dynasty is recognized from the tax-system for the merchants. Nevertheless, we must not over-estimate the volume of such business, since it was found only in the cities and not in the rural districts

CLINICAL OBSERVATIONS ON RENAL ARTERIOGRAPHY
No full textThe renal arteriography has four methods, i.e., translumbar aort o graphy, retrograde aortography, selective renal arteriography, and intravenous aortography. The author attempted clinical observations on 262 cases of translumbar aortography and 34 cases of intravenous aortography which he had performed at Kyoto Univ. during his stay there, the period of April 1953 through June 1961. Especially, the clinical value on the dynamic x-ray diagnosis by application of the seriography was discussed with given instances. 1. Clinical Observations on Renal Arteriography b y Translumbar Abdominal Aortography There were included not only urologic diseases as renal tumor and urolithiasis etc., but also renal hypertension etc., in 262 cases which the translumbar aortography had been employed. The single shoot was made on most cases, and the seriography was taken in 79 cases which included both methods the seriographic apparatus was used in 73 cases and ODELCA mirror camera was used in 6 cases. The 16 mm x-ray cinematography was taken in 8 cases for the purpose of dynamic x-ray diagnosis. Side reactions of the aortograph y were found only in 15 cases. The most of them were the irritative symptoms caused by the contrast media, and it was demonstrated that 76% Urografin (Schering) was most nonirritating. No such severe symptoms, as have been described in other references, were observed. The times of the appearances of the pictures which were shown by seriography were as follows : the shadow of the renal artery appeared during 1.0-3.0 sec., nephrogram during 2.0, -6.0 sec., renal vein during 4.0-6.0 sec., renal calyces and pelves during 50.0-60.0 sec. after the beginning of injection respectively. Some other arteries in the abdo m inal cavity as well as the renal artery appeared by this method. I n cases of renal tumor, irregular pooling pictures of contrast media in the neoplastic area appeared well, and it was shown that the picture appeared and disappeared later than the shadow of the renal artery by means of seriography. In a case of solitary cyst of the kidney, a v ascularity in the cystic area and bow-shaped blood vessels around the area appeared clearly by this method. In a cases of hydronephrosis, function of the dise a s ed kidney was well estimated and an aberrant artery obstructing the ureter was visualized by this method. A case of horse-shoe kidney was demonstrated, being one o f congenital anomalies of the kidney. In a cases of Goldblatt's hypertension a picture of the renal artery stenosis was demonstrated. In a case of abdominal aortic aneurysm, the slowed circulation in the aneurysmal part was shown but the renal arteries were normally demonstrated. 2. Clinical Observations on R e n a l A rteriography by Intravenous Abdominal Aortography This method was performed on 34 cases, mos t of whom were renal tuberculosis, urolithiasis and renal tumors etc. The single shoot was emplo y ed in most cases, and the seriography was taken in 5 cases and the 16 mm x-ray cinematography in 2 cases. The author hopes that applications of the seriography will be made in these cases to obtain clearer pictures of the renal artery. The appearance of the picture of the renal artery in seriography was during 7.0-15.0 sec. following the beginning of injection, and nephrogram appeared during 8.0-16.0 sec. and renal calyces and pelves at 90 sec. The pictures of renal artery and nephrogram in a case of ureteral calculus were demonstrated. It was shown by the seriographic method that pictures of the renal artery and nephrogram appeared late in case of the aortic aneurysm located above the renal arteryies. The intravenous aortography is more simple and more safe than the tr a n slumbar one, and has some other excellent clinical values. However, the former is somewhat inferior to the latter in a point of the contrast density of the picture. This research had been performed during the author's stay at the Kyoto University. Grateful acknowledgement is made to Prof. T. Inada for his constant interest and guidance, to the staff of the departmet of Urology and x-ray technicians of the Kyoto University for much assistance throughout this investigaiton. Thanks are also due to the NichidokuYakuhin Co., Ltd. and to the Shimadzu-seisaku Co., Ltd. for generous supply of materials and instruments
