Fifteen specimens of the Chinese false gudgeon Abbottina rivularis were collected from three rivers in the Lake Biwa–Yodo River system, Kyoto Prefecture, Japan for the first time in 38 years. A molecular phylogenetic analysis of mitochondrial cytochrome b gene sequences indicated that the specimen haplotypes completely matched two haplotypes included in the Honshu clade of the Japanese lineage, suggested as indigenous to Japan in a previous study. Further surveys are necessary to reveal the origin and distribution of the species in Kyoto Prefecture, and future conservation requirements, in addition to progressing biogeographic studies in the Kinki region.

Stands of Sugi, Cryptomeria japonica, and Hinoki, Chamaecyparis obtusa, produce 1014 pollen grains per ha per yr in a productive year and 1011-1012 grains in an unproductive one. Little year-toyear fluctuation in pollen production by stands of pioneer and secondary trees is evident, the maximum/minimum ratio within a stand being about 2. In comparison, alder stands produce 2-5×1013grains in both productive and unproductive years. Pollen production rates of Sugi stands increase with increasing age of the stand until 50 yr, showing a constant upper limit for several hundred years thereafter. With regard to year-to-year fluctuations in pollen production rates for Sugi stands, annual rates alternate from high to low every year. This rhythm may be interrupted by the accidental effects of unusually hot dry weather in late June and July. The amount of pollen dispersed into the air can be predicted from the number of male flower buds that fall before flowering in autumn and winter. Control of pollen production in forests by silvicultural techniques while paying attention to the environmental conservation of forests is considered extremely difficult.

国際社会はパリ協定で気温上昇を産業革命前比2 ℃未満に抑えると合意し,近年は脱炭素をキーワードとした目標が次々発表されている.脱炭素の実現は京都議定書に基づいたこれまでの気候変動対策に比べ遥かに野心的で社会構造の大転換が求められるが,企業が組織する経済団体からも反発ではなく脱炭素に協働するという発表が相次いでいる.本研究は,気候科学の知見・各国の経済政策・企業と投資家の取り組み・NGO等の活動に着目してこれまでの動向を調査し,どうして世界は脱炭素に向けて動き始めたのか?という背景を俯瞰的視点から明らかにする.文献調査の結果,気候科学の発展が国際合意に影響したことに加えて,企業に気候リスク情報の開示を求めるTCFD といった新たな気候変動対策ツールの整備が脱炭素の動きを後押していることが確認できた.また,民間企業でも気候リスク低減と経済的利益がTCFD等を通して結びつき,「気候変動対策はもはや社会貢献ではなく自己の存続のために必要」という当事者意識のパラダイムシフトが起きていることが示唆された.これらの気候変動対策をサポートする社会情勢の変化を背景として,世界は脱炭素に向けて舵を切ったと考えられる.

Mast cell activation is crucial to the development of allergic disease. New studies have shown that both IgE-dependent and -independent mast cell activation is temporally regulated by the circadian clock, a time-of-day-keeping system that consists of transcriptional-translational feedback loops of several clock genes. For instance, the core clock gene Clock controls the expression of the high-affinity IgE receptor (FcεRI) and interleukin-33 (IL-33) receptor ST2 on mast cells in a time-dependent manner. As a result, the threshold of IgE-dependent or IL-33-dependent mast cell activation differs between daytime and nighttime. This mechanism may underlie the observation that allergic disease shows a marked day-night change in symptom occurrence and severity. Consistent with this novel concept, environmental and lifestyle factors that disturb the normal rhythmicity of the circadian clock, such as irregular eating habits, can lead to the loss of circadian control of mast cell activation. Consequently, the degree of mast cell activation becomes equally strong at all times of day, which might clinically result in worsening allergic symptoms. Therefore, further understanding of the association between mast cell activation and the circadian clock is important to better manage patients with allergic disease in the real world, characterized by a “24/7 society” filled with environmental and lifestyle factors that disturb the circadian clock rhythmicity.

This article describes the intervention for improvement of the limitation of range of ankle dorsal flexion. A limited range of ankle dorsal flexion is caused by shortening of antagonist musde or joint capsule, decrease of joint play and disorder of the axis of dorsal flexion. Especially, a disorder of the joint axis is the most important finding among all causes. Disorder of the joint axis has a close relation with shortening of the soft tissue around the ankle joint. Especially, there are some typical parts, in which shortening of the soft tissue is related to disorder of the ankle motion axis. These parts were identified as the D-point (Daikuya's normalizing point for ankle axis). Compression and stretching to the D-point normalized ankle axis disorder. Normalizing the ankle axis is an important strategy in physical therapy for the limitation of the range of ankle dorsal flexion, because normal soft tissue is loosened and shortened tissue is untouched in physical therapy for an abnormal ankle axis.

資源小国日本にあって,日本が世界第2位の生産量を誇る資源があることをご存じだろうか。それはハロゲン元素の一つヨウ素である。ヨウ素は,チリではチリ硝石の副産物として生産される。一方,日本では天然ガスの生産の際に,汲み上げられる地下かん水と呼ばれる塩水から生産され,この2カ国で世界の生産量の約90%を占める(チリ約60%,日本約28%)。しかもその国内生産量の約75%が千葉県で生産されている。ヨウ素は1811年フランス北西部で海藻灰から発見された。その後,海藻を原料とするヨウ素産業はヨーロッパ中心に発展した。日本でも明治時代,千葉県,神奈川県,三重県などの海岸地域でヨウ素の生産が行われたが,その中でも千葉県は,最大の生産量を誇っていた。本稿では千葉県におけるヨウ素の製造法の変遷と最近のヨウ素を取り巻く環境について解説する。

In Korea, with the rapid spread of the Internet, "cyber violence" has been a social problem such as the spread of a falsehood, revealing of a real name and personal information on the Net. The suicide of a famous actress in October 2008 caused by cyber violence led the Korean government to propose "a cyber contempt charge" that imposed a severe punishment of a slander on the Internet. In this paper, based on the investigation of socio-cultural background of cyber violence in Korea and the trend of law development by the Korean government, the author examines the propriety of the cyber contempt charge. Furthermore, on the basis of consideration of the recent court cases of libel on the Internet in Japan, the author proposes a recommendation of the method for protecting the freedom of speech on the Net from the viewpoint of "information ethics".

What is the exact relationship between analytic philosophy and philosophy of science? In this paper, I will address this question from the perspective of research traditions, with the help of recent historical studies on analytic philosophy. The two groups are particularly focused: the Polish philosophers and the logical empiricists in Berlin. Neither of them is unknown to us. However, by taking seriously their connection to the development of analytic philosophy and philosophy of science as research traditions, I believe, the understanding of our own tradition may be improved.

This paper explains Japanese politics in the post-1955 system using the theory of mass politics (Kornhauser 1959). Since the prior theory of class politics does not adequately explain the Japanese situation in the post-1955 system, many scholars have focused on the theory of populism, which does not regard voters as an important aspect. In contrast, the theory of mass politics consists of two aspects that are connected by public opinion: available politicians and accessible voters. The former is synonymous with the concept of populism, and the latter concerns those who are socially and politically marginalized. This paper focuses on the breakthrough of the Toru Hashimoto camp in Osaka as a model case for Japanese politics in the post-1955 system. Voting behavior in the Osaka mayoral election of November 27, 2011, is analyzed using a social survey on political attitudes and civic participation in Osaka City. Path analysis is used to examine the model, which is based on the theory of mass politics. The results are as follows: (1) CFI and RMSEA values show the validity of the analytical model; (2) voters who are socially and politically marginalized voted for Hashimoto because of their distrust of public officials; (3) voters who are not socially and politically marginalized voted for Hashimoto because they favored the competitive principles of the market (neo-liberalism); and (4) there are no indirect effects of voters’ socio-economic status on voting behavior. Therefore, mass politics modified by both accessible and non-accessible voters is confirmed. Based on these results, a framework can be presented for analyzing Japanese politics in the post-1955system.

The behavioral immune system (BIS) regulates one’s cognition, emotion, behavior for avoiding diseases. History shows that disgust as the key component of the behavioral immune system has played a crucial role in the spread of extreme out-group exclusion. This article aimed to examine how the BIS influences negative attitude towards the specific group. A broad range of literature review suggested that the fundamental principles of the BIS, smoke-detector principle and functional flexibility principle, are essential for understanding this issue. Previous studies showed individual differences in disgust sensitivity and perceived vulnerability to disease affect the negative attitude towards the specific group based on the BIS. Presence of disease cues also facilitates the formation of such attitude. In addition, the literature review revealed information provides the disease context can easily alter an individual’s attitudes towards the specific group in a negative direction. Furthermore, based on these findings, the direction of future research is discussed.

Offshore wind climate along the coast of Kanto area was investigated by a mesoscale model and wind energy potential considering economical and social criteria was estimated by Geographical Information System (GIS). The prediction accuracy of the annual mean wind speed by the mesoscale model was 4.8%. The estimated wind climate shows that offshore Choshi, the annual mean wind speed is significantly higher than other area. Without considering any economical or social criteria, the total potential along the coast of Kanto area is 287TWh/year, which is almost equal to the annual supply of Tokyo Electric Power Company. If only the bottom mounted foundation is used, the potential varies from 0.21TWh/year to 7.98TWh/year depending on the scenario. On the other hand, when floating foundation is taken into consideration, the potential is 100.59TWh/year even for the most conservative scenario.
