An almost complete adult male skull, two incomplete adult female crania, and several adult limb bones of the early historic time (the Heian period), discovered in the Tekiana cave site on Tobi-shima Island in the Sea of Japan, were measured and described. Comparison was made with the recent Japanese, protohistoric Japanese of the Kofun period, the Jomon remains, the recent Ainu in Hokkaido, and a nearly contemporary skeletal series from Troickoe in the Amur valley. The male skull showed the closest resemblance to the Jomon remains, and the two female crania were closest either to the protohistoric Kofun series or the recent Japanese, both in metric and morphological comparisons. This probably implies that there was some element retaining archaic Jomon-like morphological features among the population of early historic times in the northern part of Honshu Island.

経鼻投与は、血液脳関門(BBB)を介すことなく脳内に薬物を非侵襲的に送達する新たな投与経路として期待されている。これには、鼻粘膜透過性や脳への移行性を高めるDDSキャリアが必要である。本稿では、細胞透過性ペプチド修飾高分子ミセルの経鼻投与用キャリアとしての有用性について、脳内への薬物および核酸の送達性、ならびに脳腫瘍モデルラットにおける治療効果など、我々の持つ知見をもとに紹介する。

The radioactive cesium released by a nuclear plant accident was dissolved in rainwater and deposited on the land surface. The nuclide was adsorbed strongly by clay fraction as soon as it contacted with the soil and remained in the soil outer layer. Plants absorb various kinds of substances with water from their root, but the cesium in the clay is hardly absorbed.On the other hand, the nuclide moves more easily in sandy soil, peat soil and organic matter layers that accumulated on the forest floor. When cesium is deposited on organic matter, it can be absorbed by plants. The translocation pattern in plants is similar with that of potassium ; transferring and accumulating in the growing part. In the river water, the radioactivity is detected when the soil sediment is contained. It is important to take means not to move a surface soil from the contaminated sites. In forest environments, cesium moves in the ecosystem. The survey of the nuclide deposition at one and a half years after the accident revealed that the radioactivity in the coniferous leaf or bark is approximately reduced to half and that in the soil outer layer increased by degradation of organic matters followed by downward movement by precipitation. The nuclide adsorbed by the soil is hard to move outside the system without artificial disturbance. However, the outflow of the soil by the muddy water is concerned in a steep slope. The preventive measures with an artificial pond, a ditch or the wall will restrain re-pollution.

Knowledge of radioactivity levels and the behavior of radionuclides in the environment are important in terms of radiation protection. Artificial radionuclides are already distributed in the environment as products of atmospheric nuclear tests and nuclear power plants. However, naturally occurring radioactive material (NORM) and technologically enhanced NORM (TENORM) associated with consumer goods have also become of concern. Radon, for example, represents a large contribution to natural radiation. The Japan Chemical Analysis Center (JCAC) has carried out a series of nationwide surveys under the auspices of the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan. This communication presents an outline of the environmental radioactivity survey and its implementation by the JCAC.

While the consumption tax rate in Japan is 5% as of 2013,the government plans to increase it to 8% in 2014 and to 10% in 2015.However, the government will also introduce reduced tax rates on certain items for the low-income group. In this study, we use an optimization method to remove regressivity of reduced tax rate and then analyze the optimal solutions.

SHINOZAKI, K., K. YODA, K. HOZUMI ard T. KIRA (Osaka City Univ., Osaka) A quantitative analysis of plant form-the pipe model theory. I. Basic analyses. Jap. J. Ecol. 14,97-105 (1964). Examining the profile diagrams of various plant communities showing the vertical distribution of the amounts of leaves and other non-photosynthetic organs at respective horizons above the ground, a close correlation was found between the distributions of the two amounts. The amount of leaves existing above a certain horizontal level in a plant community was always-proportiona1 to the sum of the cross-sectional area of the stems and branches found at that level. This led to a new interpretation of plant form, in which the stem and branches were considered as the assemblage of unit pipes each supporting a unit amount of photosynthetic organs. In trees, the disused pipes, which had once supported the leaves on the already shed-off branches, remain in the trunk and boughs together with the working pipes connected with the living leaves. A specific shape of tree Shoot is thus formed. This pipe model theory on tree form proved to be applicable to various conifers and hardwoods.

The contemporary society, at which modern society could finally arrive, is a mass societywhere the average vulgar mass-man is contented with good facilities in a modern civilization.Such a mass-man entirely disregards the value of tradition in the historical past, deeplyimmerses himself in self-satifaction, and oversympathizes with anonymous others. Above all things, I think, it is the absence of the historical past and tradition in the presentday that roduces the basic cause of the conditions of mass society in our time. In thispaper, I will study the opinion of J. Ortega y Gasset, the Spanish philosopher who isworldwide famous for his "The Revolt of the Masses" published in 1930, about the "Past",that is to say, the past and tradition in history. In Japan, the Third Opening has inaugurated revisions of the Japanese Constitution and theFundamental Law of Education. These revisions may add the concepts of history andtradition to two fundamental laws, because the active Constitution and the Fundamental Lawof Education are lacking in these concepts. Ortega, the philosopher who belonged to the school of Philosophy of Life in the history ofwestern thoughts, attempted to establish his philosophy of vital reason or historical reason,by criticizing modern rationalism and by emphasizing the importance of life, particularlypastness and futurity on the base of presentness in the temporality of life. And also Ortega,the transitional philosopher from modern to postmodern times, showed an ambivalent attitude,negative and positive, toward the past and tradition in premodern history which wasrefused by the modern era. Therefore, I will try to clarify Ortega's opinion on the "Past" inhistory, particularly historical past, traditionalism, and feudalism, by applying to them thetheory temporality which consists of pastness, presentness, and futurity in subjective time.Pursuing and considering the "Past" in history, Ortega discovers the historical structure ofhuman beings, the actual exstence of historical past, the value of tradition, and thespiritualism of feudalism. And moreover, he catches the dualism of passive, traditional, andinertia power - pastness - and positive, challenging, and active power - futurity -, in humanbeings both as individuals and as groups.Finally, I intend to find the interaction of pastness and futurity in Ortega's view of the"Past" in history, confirming the actuality of historical past, the value of tradition, and thejustification of feudalism.

水稲の周年養液栽培法と生産性の高い栽培技術を確立する目的で, 高圧ナトリウムランプとメタルハライドランプを設置した完全制御室, 太陽光併用高圧ナトリウムランプ室, 混合光室, メタルハライドランプ室および太陽光室を利用し, 1994~1995年に3回, 栽培試験を行った.<BR>PPFDの大きさは補光ランプを点灯した完全制御室>高圧ナトリウム室>混合光室>メタルハライド室の順で, 太陽光室は最も小さかった.PPFDは玄米重との間で有意な正の, 屑米重歩合との間では負の有意な相関がみられた.また, 玄米重を決定する変数増減法により重回帰分析を行った緒果, PPFDは第1ステップで取り込むと寄与率は96%で, 水稲の生育・収量に大きく影響を与えていた.とくに完全制御室と混合光室では, ランプの光合成増進効果により生育・収量は優るとみられた.また, 全平均照度は玄米重の決定に寄与するが, PPFDよりも寄与率は大きく劣るとみられた.このように, 高圧ナトリウムランプおよびこれとメタルハライドランプの混合光およびこれに太陽光を併用した場合は玄米重は増収し, 植物工場における増収技術になると考えられるが, 実用場面ではさらに検討を要する.<BR>本論文を作成するにあたり, 弘前大学農学部卜蔵健治教授から有益なご教示を賜った.また, 青森県農業試験場育種部長中堀登司光氏, 同前栽培部長玉川和長氏には調査にご協力を戴いた.ここに厚く謝意を表する.
