本原稿では,女子及びジェンダーマイノリティの大学生・大学院生(以下,女子学生)によるプログラミングの学習が,プログラミングの動機づけにどのように影響するのかを検討することを目的に調査を行った.女子学生を対象に2週間のプログラミングのコース(Waffle Collegeエントリーコース)を実施し,コース実施前後に期待-価値モデルを適用した,プログラミングの動機づけに関する質問紙調査を行った.その結果,成功期待,実践的利用価値が有意に増加し,心理コストが有意に減少した.また機会コストは有意に増加したことが示された.

Multiple shoots were induced by shoot-tip cultures of 5-month old juvenile seedlings of Cedrela odoraia L. on woody-plant medium supplemented with 6-benzylamino purine (BAP). A small concentration of BAP (0.2mg/l) was suitable for shoot proliferation and their later elongation. Large rooting percentages (90%) were obtained on half-strength amounts of the same initial medium containing low levels of indole-3-butyric acid (IBA) and naphthaleneacetic acid (NAA) (IBA 0.5mg/l and NAA 0.05mg/l) . Rooted shoots were transferred to perlite substratum for root development and further plantlet growth.

喘息患者132名に常用抗原28種の皮膚スクラッチ反応を実施し, 別に主要抗原5種 (室内塵, チリダニ, スギ, カモガヤ, ブタクサ) については大部分の対象に各反応と無関係に皮内反応闘値, RAST値, ELISA値を測定した. この対象者の主要抗原は室内塵, チリダニ, スギ, カモガヤ, オオアワガエリ, ブタクサだけであった. 皮膚反応は若年層で陽性に出やすく (90%), 40歳以上で半減した. RAST値と皮内反応閾値の年齢別検討で特異的IgE抗体の年齢による産生低下が考えられる. 陽性率の比較で皮膚反応の感度が高く, RAST値はやや劣るが陽性者の一致率はよい. ELISAは感度は良いが上記2者と陽性者が必ずしも一致しなかった. 室内塵とチリダニは抗原性に高い相関があるが, 一方だけ陽性例も少数あった. 皮内反応閾値とRAST値はよく相関するが, ELISA値とは相関が低下した. RAST, ELISA値も相関が低い.

<i>Jacaranda mimosaefolia</i> D. DON was regenerated by shoot-tips subcultured on GAMBORG'S basal medium with the largest concentration of kinetin [6-furfurylaminopurine] (KIN) (100 &mu;M). After six weeks of culture, a six-fold multiplication rate was achieved. Rhizogenesis frequency was 100% on half-strength amounts of the same initial medium containing indole-3-butyric acid (IBA) (0.49, 4.9 &mu;M) alone, or in combination with naphthaleneacetic acid (NAA) (0.27 &mu;M). Rooted shoots were transferred to vermiculite substratum and acclimated successfully in a growth cabinet.

The aim of this study was to identify the features of isokinetic shoulder and trunk muscle strength of volleyball attackers with shoulder problems and to compare them with those of baseball pitchers.18 competitive high school volleyball attackers and 16 competitive high school baseball pitchers were studied.6 of the attackers and 7 of the pitchers were suffering from shoulder pain but the other players had no history of shoulder pain. The tests were conducted using a Biodex system 3 multi-joint dynamometer. The shoulders were tested for their flexion and extension muscle strength on the scapula plane and trunk muscle strength were tested for their flexion, extension and torso-rotational strengths. The results were compared between the normal group (N-G)and the shoulder injured group (S-G) and also between the attackers and the pitchers. We observed weakness of shoulder flexion strength in S-G of both athletes and the flexion to extension muscle strength ratio was significantly lower in S-G of the attackers. We also noticed the decline of trunk torso rotation to shoulder extension muscle strength ratio in the same group. In comparisons between the attackers and pitchers of N-G, trunk flexion to extension muscle strength ratio of attackers was significantly higher. The reason of the above results, we assumed that the force created from lower extremities was used for jumping in volleyball, while in baseball, it is used for pitching. We also considered that force required for spiking is created from the trunk in volleyball. Characteristics of shoulder muscle strength as dynamic stabilizer are similar in both volleyball and baseball. Appropriate proximal kinetic chain rehabilitation for the leg, hip and trunk should be selected in accordance with the characteristics of sports activities to prevent shoulder injuries. Especially for volleyball attackers, trunk muscle training is a prerequisite to prevent shoulder injuries.

This report showed that the analysis of the isokinetic strength test for throwing shoulder injuries could be used to determine the appropriate time for the patient to return to pitching. During the last six years, among two hundred sixtyfive players studied, one hundred fifty high school baseball players were found to be uninjured while one hundred fifteen players were found to be suffering from throwing shoulder injuries. The tests were carried out using a CybexR II Multi-Joint Dynamometer. The patients were seated with their shoulders abducted at 90 degrees and their elbows flexed at 90degrees. The shoulders were tested for their rotational strength. We observed an imbalance of isokinetic strength of the shoulder by noticing a difference between the internal and external rotational strengths. In addition, we examined the data of concentric isokinetic endurance strength that had not been reported previously. Returning to pitching was found to be highly possible when the patients corrected the imbalance of internal and external rotational strengths and their concentric isokinetic endurance strength was above 70% measured by the concentric endurance strength test. Correction of the imbalance of internal and external rotational strengths and the improvement of endurance strength were considered to be necessary to judge the appropriate time for returning to pitching.
