2015年5月~2016年11月に,福島県内の阿武隈川水系の13定点においてさし網や延縄などを用いた調査を行い,716個体(体長9.9~65.0 cm)のチャネルキャットフィッシュが採集された。本種は阿武隈川の本流で採集され,特に発電用ダム(信夫ダム,蓬莱ダム)の貯水域やその下流域で多く採集された。信夫ダムでは,2008年に比べて CPUE が著しく増加していることや,GSI の高い成熟個体や未成熟の小型個体が多く採集されたことから,近年,ダム周辺の水域を中心に,再生産により本種の個体数が急激に増大している可能性が考えられた。雌の GSI の季節変化より,本水系における産卵期は5~6月ごろと推定された。信夫ダムにおいて,さし網および延縄により採集された魚類のうち,本種が占める割合は非常に高く(各64.2%および100%),本水系における適切な駆除手法の確立が急務であると考えられた。

The health hazards posed by Virtual Reality (VR) environments can be divided into two groups based on their developing mechanism. The first group is related to optical stimulus load and is exemplified by Visual Display Terminal (VDT) Syndrome. The second group encompasses those caused by space information confusion and is exemplified by VR sickness. Among space information confusion induced hazards, VR sickness is especially serious because it can involve strong discomfort, headache, nausea and vomiting. Because VR sickness may prove to be a barrier to the spread of VR environments, it is thought that countermeasures are required. This paper reports the current state of VR sickness countermeasure knowledge. Research is summarized and organized mainly according to the following stories: "Cognition of VR sickness", "Mechanisms involved with the development of VR sickness", "Directions for countermeasure development" and "Evaluation of VR sickness".

The Hosokura Metal and Mining Co., Ltd. produces electrolytic lead (99.99% purity) and bismuth, antimony trioxide, crude silver etc. from recycled lead-acid batteries and various types of lead-bearing industrial intermediates. Mining and smelting of lead, zinc and silver bearing ores from the original Hosokura Mine began over 1,200 years ago, but was terminated with the closure of the mine in 1987 and, since then, the production of recycled lead and the treatment of mine wastewater have been continued. The current company was reorganized in March, 2006. Although the capacity for monthly lead production based on a blast-furnace operation followed by electro-refining is around 2,000 t /month, a serious shortage of recycled batteries triggered technology development to accept lead dross and lead residue etc.also as low grade raw material in the summer of 2005. Another main operation of this company is the treatment of mine wastewater, 15 t /min on average, from the closed mine and the effluents from lead plants to meet the water quality standard against toxic elements including lead. Overcoming the lead-leakage problem at this plant in May, 2002, the thoroughly renewed and strengthened water-treating system with a big deep bed filtration facility at the final stage enables us to contribute to the environment improvement of this area and rebuild the tight, friendly correlation with the surroundings. Both the plants are operating under the company policies of environmental conservation, compliance and community involvement.

Thin films have recently emerged as one of the most important building blocks of nanotechnology and are often prepared under vacuum conditions. For efficient production of high-quality thin films, it is important to understand the impact of the vacuum on each stage of the thin film deposition processes, including decomposition of the starting material, transport of its vapor, and deposition. This article discusses the general key aspects of the thin film deposition process from the viewpoint of vacuum science and technology.

The five-minute music program 'MINNA NO UTA' (Everyone's Songs), which has been broadcast on NHK since 1961, has contributed to the popularization of new children's songs. It has created about one thousand tunes, influencing musical education and popular music in Japan. This paper explores the characteristics and meanings of this program by focusing on its text as well as the processes of its production and consumption. My research involved conducting interviews with directors and distributing questionnaires to audiences. My aim is to explain the uses of this program by audiences through their everyday lives and how this TV program contributes to creating new children's songs. My conclusions are, firstly, that this program has a distinctive history that has been flexibly transforming songs into appropriate styles for children in the TV age. Secondly, these songs played a role in constructing a national collective identity for everyone (including grown-ups), especially from the 60s to the 80s, because these texts have functioned as 'national music' mediated by a state channel.

This article analyzes the shunga collection owned by the Mito Tokugawa family. It presents the discovery of six pieces from the Mito Tokugawa, one of the three branches of the Tokugawa. This collection helps us understand the uses and the spread of erotic art among the ruling classes in Edo period Japan. The collection, formed of different types of works (scrolls, books, prints, and sex toys) is important in documenting the high degree of acceptance of erotic art within the Tokugawa family. In particular, the manuscript notes written by the daimyo, Tokugawa Nariaki, show that the works were acquired as part of a regular family practice over the seventeenth, eighteenth, and nineteenth centuries. This suggests that it was common for all daimyo families to collect shunga.

Building on a growing body of literature in international and comparative politics on transitional justice, this article examines the debate as to whether international criminal justice contributes to peace. The establishment of the International Criminal Court (ICC) has often been hailed as the culmination of international human rights standards that have been developed and advanced as norms following World War II. Yet the ICC's prosecution activities have been criticized by those who argue that the threat of punishment causes dictators to cling to power, resulting in delaying the end of conflicts or a smooth transition to democracy.<br>This article demonstrates how the "peace vs. justice" debate is rooted in opposing ideas for fostering international peace, both premised on the decentralized nature of international society, and how the tenets for their arguments are being shaken when faced with the reality of international human rights protection. Advocates for international criminal prosecution believe that strengthening centralized law enforcement authority beyond sovereign states will deter future atrocities. Given that a victor's justice is no longer tolerated on one hand and that there is no world government in sight on the other, however, efforts to make credible the threat of prosecution would remain incomplete. Meanwhile those who criticize the ICC as an idealistic endeavor find the basis of international order in bargaining that occurs within sovereign states, but their logic is difficult to sustain because the ICC is making the promise of amnesty, considered crucial to strike a compromise, less credible.<br>The article argues that international criminal prosecution should be understood as part of the international community's efforts to intervene in and improve internal governance of weak, failing or collapsed states. The limits of the ICC lie not just in weak enforcement but in the very act of questioning the legitimacy of leaders who are caught in conflict. International human rights norms encourage democratized states to address past human rights violations committed under previous regimes; however, they do not solve the problem of how to deal with perpetrators who are currently engaged in violence during times of democratization and peace negotiations. To make international criminal prosecution a viable force for the prevention of future atrocities, it must be coupled with assistance to domestic civil society, which has to bear the consequences of these ultimate decisions.

ナンプレは世界中に広まっているペンシルパズルであるが,その1種に「斜め四独」と呼ばれるものがある.これはサイズが 4 × 4 のナンプレパズルであり,通常のナンプレのルールに「対角線上のマスにも1〜4の数字が一つずつある」というルールを追加したものである.本論文ではこの斜め四独に注目し,斜め四独の問題が適切であるための必要十分条件を明らかにする.また,得られた結果を用いて,手動で斜め四独の問題を作成する手順を提案し,斜め四独の問題の数え上げを行う.
