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, e. g. 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.

Pharmacy is required to shift toward human service such as hearing the complaints of health. But the study about help-seeking behavior to pharmacist is not really investigated. We hypothesized that a decrease in expression visibility, due to pharmacists' typical masks, may negatively impact help-seeker' trust in pharmacist. The sample included 100 drugstore customers aged ≥18 years. Participants were stratified by gender and randomly assigned to two groups: evaluation of clear-masked and normal-masked pharmacists. After viewing a video with either male or female pharmacists wearing either clear or normal masks, participants completed a questionnaire. The primary outcome was trust in pharmacist measured by the Trust Scale and the secondary outcome was impression of the pharmacist measured by nineteen pairs of adjectives. There were no differences by gender on trust scores. Results revealed that both male and female pharmacists who wore clear masks were rated as more trustworthy than normal-masked pharmacists (p<0.001, d=0.903, and p=0.001, d=0.716, respectively). Sixteen of nineteen adjectives reported for pharmacists wearing normal masks indicated greater negative intention than those with clear masks (d=0.431-1.469). In most cases, among pharmacists wearing clear masks, results showed positive correlations between trust and each impression adjective (r=0.279-0.710). Our findings indicate that pharmacists wearing normal masks, which partially hide facial expressions, may decrease customer's trust in pharmacist. Further, normal masks were associated with negative impression. To avoid the inhibition of help-seek behavior, we recommend that pharmacists wear a clear mask and increase non-verbal communication.

We present 3 cases of ocular syphilis in patients who had been newly diagnosed as having HIV. All the patients had only complained of ophthalmologic symptoms at the time of their initial visit. Treatment with penicillin was successful, resulting in no significant sequelae. Ocular syphilis may lead to reduced visual acuity or even blindness if left untreated. However, the diagnosis may be challenging, since patients may lack symptoms that are commonly observed in cases with primary and secondary syphilis. Considering the recent increase in the number of syphilis patients, clinicians should be aware of ocular syphilis and should have a high index of suspicion for syphilis in any patient at risk so as to ensure a prompt diagnosis.

Snowmelt-type mudflow is often observed when a pyroclastic flow, surge, blast or a hot-debris avalanche moves over a snow-covered slope. We constructed the experimental equipment to simulate snowmelt due to high-temperature rock fragments moving over a snow-covered channel. The experiments were carried out for nine different cases, changing the parameters of temperature, rock particle diameter, and snow density. On comparing the hydrographs of these nine cases, we found that the following conditions lead to rapid snowmelt and large peak flow : (1) the temperature of the pyroclastic material is sufficiently high ; (2) the snow density is remarkably high, as in the case of solid ice ; and (3) snow is saturated with liquid water, as in the case of slush. The results indicate that the volume of the snowmelt-type mudflow particularly depends on the snow density and the temperature of the pyroclastic materials.

Over more than one century since 1894, cymothoid isopods attached by the diclidophorid monogenean Choricotyle elongata (Goto, 1894) in the mouth cavity of Japanese sparids have not been exactly identified. This note reports that those isopods are identifiable as Ceratothoa verrucosa (Schioedte & Meinert, 1883) based on material of the species attached by Ch. elongata in the mouth cavity of a red seabream, Pagrus major (Temminck & Schlegel, 1843), from the Seto Inland Sea.

症例は20歳代男性.倦怠感と心窩部不快感を主訴に受診し,血液検査でT.Bilと肝胆道系酵素の上昇を認めた.肝炎ウイルスマーカーは陰性で,自己免疫性肝疾患なども否定的だった.画像検査で器質的疾患を疑う所見もなかった.漢方薬の内服歴があり,入院時より腹部に褐色調の皮疹が認められたため薬物性肝障害を考え経過観察した.肝生検組織では急性肝炎と診断し,薬物性肝障害として矛盾しない所見だった.肝胆道系酵素異常は遷延し,腹部の皮疹が上腕・大腿にも拡大した.再度詳細に問診を行うと不特定の性交渉歴があり,血液検査を追加し,早期梅毒と判明した.Amoxicilin 750 mg/dayの内服で,皮疹の改善とともに遷延していた肝胆道系酵素異常は速やかに正常化した.近年,梅毒感染者は増加傾向にあり,特に若年層での感染が目立つ.皮疹を伴う原因不明の肝障害患者では,梅毒性肝炎も念頭に入れるべきだと思われた.

[Purpose] The aim of this study was to access the flexibility of the spine in women practicing yoga as a part of the “University for Health” project. [Subjects and Methods] The study included 56 women ranging in age between 50–79 and attending 90 minutes hatha yoga sessions once a week. The measurements were performed twice-at the beginning of the project and after its completion, i.e., after 20 weeks of classes. The range of spine mobility in three planes was measured using a Rippstein plurimeter. The range of motion in the sagittal and frontal planes was measured in a standing position with the feet hip-width apart. The torsional range of motion of the subjects was measured with the trunk bent at a right angle and the legs apart. The flexibility ranges of the spine and hamstrings were also measured by the toe-touch test in a standing position. [Results] This study showed that the applied yoga exercises increased spinal mobility and flexibility of the hamstring muscles regardless of age. [Conclusion] Yoga exercises should be recommended to the elderly to make their muscles more flexible and to increase the range of motion in the joints, which is particularly important for improving their life quality.

本論文の目的は,二者関係データをマルチレベル分析に適用した場合に生じるいくつかの問題点についてとりあげ,その問題がなぜ生じるのか,そしてどのようにそれを解決するかについて提案することである。1つは,ペアデータの平均値を階層線形モデル(HLM)のレベル2の説明変数として用いるときに生じるバイアスの問題をとりあげた。シミュレーションの結果,HLMでは深刻なバイアスが生じる一方,マルチレベルSEMではそのバイアスが生じないことを示した。次に,ペアデータに対してマルチレベルSEMを適用した場合に生じる不適解の問題を取り上げた。ペアデータはペアレベルの推定が不安定になりやすいため,分散が負に推定される不適解が頻繁に生じる。この問題について,いくつかのサンプルデータからベイズ推定を行うことで回避できることを示した。最後に,マルチレベルSEMの個人レベル効果の解釈の難しさについて議論した。

国旗・国歌法制定後,公立学校では「国旗掲揚」「国歌斉唱」を拒む教師に対し,行政上の懲戒処分などの法的措置を含む有形無形の圧力が以前より強くかけられている。こうした中で,筆者の勤務する私立中学・高等学校では,従来慣行として行われてきた「君が代斉唱」を卒業式・入学式の式次第から削除した。この根底には,卒業式・入学式において「君が代斉唱」は不可欠の構成要素ではあり得ないという認識がある。本来,学校の設置主体が公立であれ私立であれ,いかなる卒業式・入学式をおこなうかについては,各学校がそれぞれ自主的に決めるべき問題であり,国旗・国歌の強制は憲法に違背する行為である。
