【目的】日本における車椅子テニス選手の躍進は目覚しく、ワールドカップ等でも上位に食い込み活躍を見せている。長野県においてもジャパンカップ車椅子テニス大会が開催され、昨年度で第20回を数える。長野県理学療法士会では十数年にわたり、大会期間中の理学療法サービスを実施してきた。今回はスポンサー撤退により、大会が縮小した過去2年間の大会に限定し、車椅子テニス競技の障害特性について報告する。<BR>【方法】大会会場に理学療法室を設置し、治療用簡易ベッド、物療機器、テーピングテープなど用意し、理学療法士を7名程度常勤させ、期間中選手がいつ来室しても対応できる体制をとった。利用が込み合う時間帯は予約制とし、スムーズに運営できるように配慮した。<BR>【結果】過去2年間の大会参加選手のべ112名。理学療法サポート利用選手のべ59名であった。試合前の利用者は11件。試合と試合の間18件。試合後30件であった。障害部位の内訳としては、肩甲骨周囲筋群22件、肩関節6件、利き手肘外側8件、利き手肘内側6件、その他手関節、頚部、腰部等20件であった。症状は筋硬結24件、疲労21件、運動時痛21件、圧痛15件、その他19件であった。障害期は急性期5件、亜急性期3件、慢性期51件であった。対応はマッサージ37件、ストレッチ29件、アイシング8件、テーピング4件、物理療法4件、その他9件であった。<BR>【考察】車椅子テニス競技は、利き手にラケットを握り、車椅子を操作(以下チェアワーク)しながらプレーする競技である。ターン、ダッシュ、ストップなどのチェアワークは勝敗の鍵を握る1つで、練習でも重要視されている。障害発生要因は利き手側の過用症候群のみではなく、チェアワークによる要因も大きいと考えられる。また、車椅子をすばやくターンするときには、上肢のみでなく頚部、体幹、腰等を回旋させているため、頚部・腰等に障害を抱える選手が多いとも考えられる。<BR>【おわりに】障害者スポーツ大会は、スポンサーの有無によりその規模がかわってしまい、かつメディアの注目度はけっして大きくはない印象にある。一方選手の身体特性は元来から有する障害に加え、スポーツ障害を併発しているため、複雑化している場合も多い。当士会では、1998年に冬季パラリンピック大会を支援した経験があり、その事を生かしながら、今後も障害者スポーツの活動を支援してゆきたいと考えている。

The spectral sensitivity of the posterior median eye of the jumping spider, Hasarius adansoni, was investigated by recording electroretinograms. The spectral sensitivity curve had a maximum peak at about 340-360 nm and an additional small peak at about 480 nm. The effect of UV light on behavior was examined with freely walking spiders. The experimental arena was cylindrical, about 65 mm in diameter and 3 mm in height, and covered with a quartz glass sheet. When one half of the arena was illuminated with a 360 nm light and the other half was illuminated with a 540 nm light, spiders walked longer period preferentially under the 360 nm light than under the 540 nm light. When the posterior median eye was occluded with black paint, some spiders walked longer period under the 540 nm light than under the 360nm light. We conclude that the posterior median eye is a UV receptor.

Aim: The prospective, randomized, multicenter Myocardial Ischemia Treated with Percutaneous Coronary Intervention and Plaque Regression by Lipid Lowering & Blood Pressure Controlling assessed by Intravascular Ultrasonography (MILLION) study demonstrated that combined treatment with atorvastatin and amlodipine enhanced coronary artery plaque regression. Although the baseline high-sensitive C-reactive protein (hs-CRP) reportedly plays an important role in atherogenesis, few data exist regarding the relationship between hs-CRP and plaque regression in patients receiving a combined atorvastatin and amlodipine therapy.Methods: A total of 68 patients (male, 55; mean age, 64.2 years) with baseline and follow-up 3-dimensional intravascular ultrasound examinations in the MILLION study were stratified by baseline hs-CRP level quartiles. The serial measurements of lipid, blood pressure, and percentage changes in the plaque volume were compared between the groups, and the factors associated with the percentage change in the plaque volume were assessed.Results: There were no significant between-group differences in the extent of change in low-density lipoprotein cholesterol (LDL-C) or systolic and diastolic blood pressure after 18–24 months of treatment. The percentage change in the plaque volume showed a linear association with the baseline hs-CRP (p for trend <0.05); however, there was no correlation with changes in LDL-C or systolic and diastolic blood pressure. In the multiple regression analysis, the baseline hs-CRP level was independently associated with the percentage change in the plaque volume (β=0.29, p=0.022).Conclusions: Coronary plaque regression was associated with the baseline hs-CRP level in patients treated with a combined lipid- and blood pressure-lowering therapy.

In this paper, a novel position sensorless control method for interior permanent magnet synchronous motors (IPMSMs) that is based on a novel flux model suitable for maximum torque control has been proposed. Maximum torque per ampere (MTPA) control is often utilized for driving IPMSMs with the maximum efficiency. In order to implement this control, generally, the parameters are required to be accurate. However, the inductance varies dramatically because of magnetic saturation, which has been one of the most important problems in recent years. Therefore, the conventional MTPA control method fails to achieve maximum efficiency for IPMSMs because of parameter mismatches. In this paper, first, a novel flux model has been proposed for realizing the position sensorless control of IPMSMs, which is insensitive to <i>L<SUB>q</SUB></i>. In addition, in this paper, it has been shown that the proposed flux model can approximately estimate the maximum torque control (MTC) frame, which as a new coordinate aligned with the current vector for MTPA control. Next, in this paper, a precise estimation method for the MTC frame has been proposed. By this method, highly accurate maximum torque control can be achieved. A decoupling control algorithm based on the proposed model has also been addressed in this paper. Finally, some experimental results demonstrate the feasibility and effectiveness of the proposed method.

Electric power is in great demand, and it is transmitted to distant places for consumers with high efficiency, where various insulators are being used for power transmission and distribution line for insulation.<br>Insulators contaminated by salt particles have been causes for flashovers on the surface under high voltage in humid climate and light rain. Rapid salt contamination of the insulator surface by typhoons has been investigated on the campus of University of the Ryukyus for several years.<br>The results obtained from the exposure tests are:<br>(1) Accumulative contamination of the insulator surface occurred always on the bottom surface of the insulators, and on the upper surface of insulators during the period without rainfall.<br>(2) The extent of contamination of the pin-type insulators with the saltproof dishes was 1/2_??_1/6 in comparison to that of pin-type insulators without ones.<br>(3) The salt contamination of the insulator surfaces is almost always influenced by wind speed and precipitation.<br>(4) Flashover voltage of salt contminated insulators by typhoons drops to approximately 1/10 of that for clean and dry insulators.

For statistical analysis of 24-hour recordings of arterial pressure (AP) and heart rate (HR), it is necessary to establish a theoretical probability density function of the distributions. In the present study, 24-hour recordings of direct AP and HR were performed in 15 normotensives (NT) and 39 patients with essential hypertension (EH) by means of a new portable device with a digital memory for analyzing frequency histograms. In both NT and EH, frequency histograms of AP(systolic and diastolic AP) and HR during a 24-hour period showed bi-modal curves, whereas those made during sleep and waking produced asymmetrical patterns resembling Gamma distribution. From the AP and HR histograms made fro each subject during sleep and waking, such parameters as mean (M), standard deviation, mode(Mo), skewness (Sk), kurtosis (K) and minimum values (Mi) were calculated. The Sk and M minus Mo were positive, and K was greater than 3 in both HR and AP histograms ; the AP and HR histograms during sleep can be more correctly analyzed with Gamma distribution (mean parameter errors were less than 7.3%) than with Gaussian distribution (in this : S=0, M minus Mo=0, K=3). The Mi would accord with the location parameter of the Gamma distribution.

Osteoporosis is caused by an imbalance between bone resorption and bone formation, which results in bone loss and fractures after mineral flux. Osteoclast-like multinucleated cells can be differentiated in vitro from co-cultures of mouse bone marrow cells and osteoblastic cells by treatment with osteotropic factors, 1α,25-dihydroxyvitamin D3 (1α,25(OH)_2D_3) and prostaglandin E2 (PGE2). During screening for osteoclast-formation suppressing effects of the extracts of various mushrooms by using the assay, we found very strong activity in the extract of the mushroom Agrocybe chaxingu. Therefore, an attempt was made to isolate the active principles from mushroom and to determine their structures. Powder of the dried fruiting bodies of Agrocybe chaxingu was extracted with CH_2Cl_2, EtOAc and then EtOH. The CH_2Cl_2-soluble fraction only showed the suppressing activity. After repeated chromatography of the fraction, compounds 1 and 2 were purified as the active principles. Osteoclast differentiation was estimated by TRAP-(+) multinucleated cell formation. The addition of compound 1and 2 (3.1μg/ml, 6.8mM) reduced the number of TRAP-(+) multinucleated cells to 66% and 0%, respectively.

In recent years, the number of osteoporosis patients is increasing. Various foods were screened for inhibition activity of osteoclast formation and we found that <I>Agrocybe chaxingu</I> showed potent inhibition activity. In this research, we tried to purify the active principle(s) from <I>Agrocybe chaxingu</I>.Powder of dried fruiting bodies of the mushroom was extract with CH<SUB>2</SUB>Cl<SUB>2</SUB>, followed by EtOAc and EtOH. After removing each solvent, each fraction was tested for the inhibition activity. Scince the CH<SUB>2</SUB>Cl<SUB>2</SUB> soluble part showed the strongest inhibition activity, the fraction was fractionated by flash column chromatography, preparative TLC, and HPLC with a C30 column. As a result, we obtained an active compound (8.1 mg) and determined its structure. This compound strongly inhibited osteoclast formation without no cytotoxicity.

明治43年(1910)8月,関東地方を中心に東日本で大水害が生じた。この対策として政府は北海道移住を呼びかけた。この呼びかけに,渡良瀬川支川思川下流部に位置する栃木県下都賀郡から66戸210名が応じた。彼らは,44年4月,現在の北海道常呂郡佐呂間町に入植し,その土地を「栃木」と命名して開墾を進めていった。明治時代,水害罹災者が北海道へ移住するのは珍しいことではなかった。明治22年の奈良県十津川災害では,十津川村から約640世帯,約2,600人が移住し,新十津川村を開いたことはよく知られているが,富山県の常願寺川水害,岐阜・愛知県の木曽川水害でも被害者は新天地を求めて移住した。また40年の富士川大水害後も,山梨県から200戸以上の移住者が北海道に向かっている。ところで栃木県下都賀郡は,明治20年頃から35年にかけて足尾銅山から排出された廃鉱(廃棄された銅分を含む土石)によって鉱毒被害が生じた地域であった。また,佐呂間町に移住した66戸の中には10数戸の元谷中村出身者がいた。このため今日,度々,この移住は足尾鉱毒事件と結び付けられて述べられている。たとえば,昭和57年(1982),開拓70周年を記念して「栃木のあゆみ」が栃木開基開校七十周年記念協賛会から刊行されたが,その冒頭に「(栃木集落は)栃木県人の皆様が足尾銅山の鉱毒に追われ,北海の新天地に永住の地を求めて移住されました」と述べている。つまり栃木集落に移住してきた人々を足尾鉱毒の被害者とし,その移住を足尾鉱毒事件の一環としてとらえている。さらに,政府による「強制移住」との主張もある。
