山形県庄内地方に発生する清川ダシの集中気象観測を行い,峡谷出口に強風域が局限される事例(Obs-1)と,全域で強風の事例(Obs-2,3)を観測した.峡谷出口でのパイバル2点観測の結果,東風成分の高度は事例によって異なり,Obs-2では下層200〜400mに最強風帯が,その上空付近には1m/s以上の強い上昇流が発生していた.峡谷出口の風速は,峡谷内の気圧傾度によって加速された,地峡風の風速と同様の傾向であったが,Obs-1ではばらつきが大きかった.付近の高層データから,全ての事例で逆転層が認められた.Obs-1では上流である仙台の逆転層が清川周辺の山脈と同程度と低く,フルード数は0.11であり,峡谷出口付近でHydraulic jumpが発生していた可能性がある.一方,Obs-2,3では仙台の逆転層が高く,フルード数は最高0.58で,強風が平野全域に現れやすい状況であったと考えられる.

Strong winds are one of the several factors contributing to natural disasters. Although in recent years, the intensity and frequency of strong winds has decreased, different areas are differently affected by such winds; these winds still have the potential to cause adverse impacts on life and property. In Korea, strong winds are also responsible for the incidence of increased number of accidents and forest fires. Therefore, in this study, relationship between wind speed and damage was analyzed, and the threshold value of damage-causing wind speed was estimated. We first analyzed the relationship between wind speed and damage occurrences based on the daily maximum wind speed and daily maximum instantaneous wind speed data, and data on damage related to strong winds. Second, we examined the validity regarding the regional segmentation of the Korean criteria of special weather report for strong winds using the critical success index and cumulative percentile distributions to estimate the damage-causing threshold value for each region. We found that damage resulting from very strong wind speeds in Korea had not occurred in recent times. In addition, considerable damage had occurred because of low-speed wind compared to the current criteria for high wind advisory. However, the incidence of damage was higher when wind speed was stronger than the current criteria for high wind advisory. Based on threshold estimation, the study areas were categorized into areas with high threshold values (coastal, mountainous, and island), and those with low threshold values (inland areas). A notable difference was observed between the threshold values of the two categories of areas. This necessitated the regional segmentation of the criteria of special weather report on strong winds.

We quantified the global bromine- and iodine-mediated tropospheric ozone loss using global chemical transport model simulations. We tested three datasets of very short-lived substances (VSLS) emissions, three datasets of sea surface iodide concentrations, and an explicit representation of the effects of multi-phase reactions at the air-sea boundary on dry deposition. We then determined optimal model settings based on the evaluation using the ship-borne and aircraft-campaign observations over the ocean. Our evaluation suggested that the explicit representation of multi-phase reaction effects substantially reduced model biases of ozone in the lower troposphere (up to 11%). Moreover, the impacts of using different datasets of VSLS emissions and sea-surface iodide concentrations were relatively small. The global bromine- and iodine-mediated chemical ozone losses were estimated to account for 4% and 17% of the total chemical loss, respectively, while the global iodine-mediated dry deposition loss of ozone was estimated to account for 22% of the global total dry deposition. These bromine- and iodine-mediated ozone losses decreased surface ozone concentrations over the ocean by 10% and 23%, respectively. The observational constraint on model simulations made by this study supports that bromine and iodine substantially impact global tropospheric ozone through atmospheric chemical reactions and dry deposition processes.

日本の「語り物」の一ジャンルである浪曲では,うたいかたる声ならびに伴奏をうけおう三味線の双方が,演じるたびごとに異なるパフォーマンスを行なうという「即興性」をもつ。本論文は,浪曲三味線の即興性のありかたの一端を探る目的のもとに,過去の録音物における「弾き出し」(前奏部分)を対象とする分析を行い,どのような枠組に基づいて即興が行なわれるのかという「見えない音楽理論」の解明を試みたものである。考察の結果,「弾き出し」末尾に位置する明確な機能をもった音型と,浪曲の史的展開の過程でストックされてきた音型の二者が,即興の準拠枠としてはたらいていることが浮かび上がった。Rokyoku, which arose in Meiji era, is a subgenre of Japanese katarimono(a narrative music), performed by a pair of a rokyokushi(a vocalist) and a kyokushi(a shamisen player). There are no notation systems in teaching and learning of rokyoku and rokyoku shamisen, and the rokyoku performances constantly include some sort of improvisation. The purpose of this paper is to examine some aspects of improvisation in rokyoku shamisen. Through analyzing the "hikidashi", i.e. the instrumental prelude part in rokyoku, the author tries to clarify some aspects of "invisible musical theory" about rokyoku shamisen. The results show that there are "guiding motifs" at the end of hikidashi which guide rokyokushi to his her vocal pitch and that there are some "formulaic figures" which have been used in rokyoku shamisen. These motifs and formulaic figures are thought to serve as the "models" of improvisation in rokyoku shamisen .

It seems to be very difficult in the Japanese criminal procedure that the accused has an opportunity to controvert the propriety of the issued warrants in the proceedings before trial. In the American judicial system, however, the defendant aggrieved by an unreasonable search or/and seizure with a warrant may make the challenge to the "sufficiency" and "veracity" of the affidavits underlying the warrant in the pre-trial suppression hearings. The author intends to clarify what principles base the right of challenge to warrants through the examination of informant's cases in the United States of America, and thereby help the solution of the same problem in the Japanese criminal justice. This paper is contended as follows : Introduction I. Preliminary Considerations 1. Pre-trial Proceedings in Federal System 2. Informants II. Challenge to Warrants 1. Availability of Hearsay Evidence in Warrant Affidavits 2. Challenge to the Sufficiency of Affidavits (1) Sufficiency Challenge (2) Two-pronged Test for Probable Cause 3. Challenge to the Veracity of Affidavits (1) Cases before Franks v. Delaware (2) Franks Decision III. Principles of the Right of Challenges Conclusion
