Dispersal tendency of the adults of the water strider, Metrocoris histro, was clarified along a stream by the mark-recapture method, over a two-month's period Phenetic differences among members of 6 local populations from 6 streams within 3 rivers was estimated using the apterous males by multivariate morphometrics. Although the adult water striders generally seemed to be sedentary within a pool, the migrants showed a downstream bias in dispersal distance and in numbers of insects moving. Discrimination analysis showed that 67%-100% of the local group members were correctly classified into the original groups, and misclassification only occured among members sampled within a radius of 8-km. Thus the present result indicated that morphological similarity among members sampled from neighbor streams was higher than that among members sampled from the distant streams in a same river. Based on these results, patterns of dispersal and phenetic differentation of M. histro were discussed.

The area restriction of shrines, enacted by the proposal of the Ministry of Finance in 1872, was flawed, because the case of reconstruction was not considered. In 1873, the Ministry of Religion ordered those shrines directly controlled by the government to submit drawings of their buildings and surrounding sites The government made the decision to preserve the design of shrines based on these drawings, while the area restriction was to be applyed to only the newly established shrines.

言葉には価値を示す言葉と事実を示す言葉とがある。その二つの性格が一つの言葉のうちで重なる場合もある。本研究では、言葉のそうした面について、参加者のさまざまな視角を提示し重ね合わせることを通して、倫理的な価値の多様なあり方の諸相を検討することを試みた。三年間の共同研究を経て明らかになったことを要約すると次のようになると思える。価値語・評価語のあり方にかかわって考えを進めるあり方には、大旨、少なくとも三つの方向がある。第一にあるのは、価値を含む言葉はそもそもどのような組成を備えて成り立つ、と見定めるのが妥当なのか、事実を示すとみなされる語と価値を示す語とは、どんな位相の差を示すものとしてあるのか、あるいはそうした位相の違いといったものなどはそもそもないと定める視点を立てることもできるのかどうか、といった点について、事を抽象する方向に眼を据えて思索を試みる、といった質の究明である。第二にあるのは、徳目としてしばしば話題にされる質の概念、あるいはもう少し広い幅で、人の価値指針となるような概念の成り立ちや意味を問う、といった視点からの究明である。儒学が倫理思想の体裁をとって問題にされる際には、そうした側面がとりわけ立ち上がることになる。旧来、この面の検討は、かなりなされることがあった、といえる。第三としてあるのは、広く日常にも用いられている言葉のうちに含まれている価値指示のあり方(たとえばさまざまな形容詞のうちに籠められているさまざまな価値内包性といったあり方)について、その意味内包のいろいろな方向の検討を試みるといった質の究明である。仔細は、報告集の参加者の論文のうちに見られる。

[Purpose] To investigate associations between vitamin C intake, physical activity, and osteoporosis among Korean adults aged 50 and over. [Subjects and Methods] This study was based on bone mineral density measurement data from the 2008 to 2011 Korean National Health and Nutritional Examination Survey. The study sample comprised 3,047 subjects. The normal group was defined as T-score ≥ −1.0, and the osteoporosis group as T-score ≤ −2.5. The odds ratios for osteoporosis were assessed by logistic regression of each vitamin C intake quartile. [Results] Compared to the lowest quartile of vitamin C intake, the other quartiles showed a lower likelihood of osteoporosis after adjusting for age and gender. In the multi-variate model, the odds ratio for the likelihood of developing osteoporosis in the non-physical activity group significantly decreased to 0.66, 0.57, and 0.46 (p for trend = 0.0046). However, there was no significant decrease (0.98, 1.00, and 0.97) in the physical activity group. [Conclusion] Higher vitamin C intake levels were associated with a lower risk of osteoporosis in Korean adults aged over 50 with low levels of physical activity. However, no association was seen between vitamin C intake and osteoporosis risk in those with high physical activity levels.

This paper reports the framework of the new view protection plan composed of the London Plan (2004) and London View Management Framework (2007) published by GLA. This new plan:1) gives Mayor of London the important role to preserve and enhance the views from the broader perspective;2) classifies views into four types and designates 26 important views;3) establishes two management approaches, Geometric Definition and Qualitative View Assessment;4) shows the location of designated views precisely by using coordinates and height;5) relaxes height restriction due to narrowing width of viewing corridors;

Stratigraphy and thickness distribution of the pyroclastic fall deposits formed during the eruption of Miyakejima volcano on October 3-4, 1983, were studied immediately after the deposition. Of the total mass of 20 million tons erupted, 8.5 million tons were ejected as basaltic scoria to form a complex set of air-fall deposits east of the fissure vents. One million tons of the latter were ejected from the upper fissures as fire-fountain products. The rest was the product of phreatomagmatic explosions which occurred in the lower fissures where ground water chilled the magma to form dense scoria blocks which devastated villages. Explosion craters and a tuff ring were formed along the N-S trending lower fissures. Account of the general distribution of the deposits, nature of the constituents, mutual stratigraphic correlation and correlation with observed sequence are given.

The recent progress of physical volcanology is reviewed focusing on studies on volcaniclastic flows and their deposits. Pyroclastic flows are high-particle-concentration, laminar currents with gas as a continuous phase. Pyroclastic surges are low-particle-concentration, turbulent currents with gas as a continuous phase. Lahars are flows of debris with liquid water as a continuous phase. Debris avalanches are catastrophic landslides in which a continuous phase is absent or plays no role for the motion. Owing to the upward gas flow, fluidization processes operate in pyroclastic flows. Flow behavior and resultant deposits are remarkably different depending the degree of fluidization, because it effectively reduces the yield strength of the flow. However, the distance traveled is slightly affected by the degree of fluidization. It is determined mainly by the mass incorporated at the source or by the velocity acquired when it wes initiated.

The eruptive history of the Kusatsu Shirane volcano is well described by means of 14 beds of key tephra and intercalating loess soil. Three eruptive stages are recognized. During early or middle Pleistocene the Matsuozawa volcano was formed; this is the first stage. The second stage was initiated by effusion of the Horaguchi lava, which was followed by eruptions of the Oshi pyroclastic flow, older lava flows, 3P pumice fall, and Yazawahara pyroclastic flow. Brown loess soil about 10m thick covering these deposits indicates that a dormant period of more than 100, 000 years followed this stage. The summit area upheaved about 400m or more against the foot of the volcano during this period, as is suggested by the extraordinarily steep (6.1°-3.0°) surface of the Oshi ignimbrite plateau. The third stage, which started about 14, 000 years ago, is the formation of three pyroclastic cones on the summit and contemporaneous effusion of the younger lava flows, <i>e. g.</i> the Kagusa lava of 7, 000 years ago and the Sessyo lava of 3, 000 years ago. In historic times, phreatic explosions have frequently occurred on the summit crater, Yugama. This means that the present belongs to the third stage. It is unlikely that eruptions of the third stage are caused by cooling of the magma chamber which was active in the second stage. The activity of the third stage seems to denote arrival of a new magma chamber at shallow depth.
