GENDER IDENTITY DISORDER (GID) is a unique human condition that is classified behaviorally and treated medically with hormones and surgery in the severe form. This condition has been and still somewhat remains controversial by religious beliefs, social institutions and health care delivery systems. We described the surgical management of transsexuals, so called SEX REASSGINMENT SURGERY (SRS) and showed the team for gender treatment, GENDER CLINIC. A gender treatment team composing staff members from the Psychiatric, Plastic Surgery, Urology, Obstetric/Gynecological Surgery, and the Social Service, was established at the Hospital of Okayama University Medical schools in 1999. Female-to-Male procedures include mastectomy, phalloplasty, Phalloplasty are completion and an appurtenance, something pleasing to others. Male-to-Female program includes the genital surgery. The genital change surgery consists of the penile inversion, orchiectomy, vaginoplasty. Other procedures include reduction thyroid chondroplasty, hair transplant, voice change, laryngeal surgery, epilation with the laser.
SRS is the only effective treatment available today in the management of GID. The aesthetic and functional results achievable from various procedures are generally satisfactory and are acceptable to the patients. On the other hand, we should remember that the numerous steps of information for SRS will be required.

従来から, 重度四肢麻痺者の日常生活を自立させるための装具, 機器が開発されてはいるが, 実用化するものは少ない. 我々は約25年をかけ, 腕保持用装具の開発を行っている. 1981年からの4年間は機能性を高めるために電動化を試みたが, 高価で故障が多く, 実用化に至らなかった. 1985年以降は簡便で故障のない腕保持用装具を目指し, 腕の牽引力をスプリングにしたポータブルスプリングバランサー (PSB) の開発と実用化に努めた. その結果, 重度四肢麻痺者の机上動作を自立させる機器として, 現在, 広く活用されるようなった. 近年はPSBの機能向上を目指し, スプリングの腕牽引力調整を利用者自らが行える, 電動モータを使用した電動式ポータブルスプリングバランサー (EPSB) の実用化を目指している.

Self-healing composites using microvascular channel networks have been intensively studied. Microvascular networks in composite in-plane directions are normally utilized to deliver healing agents to damaged areas. However, this channel configuration is not optimal to form robust networks and to infuse large damaged areas. This study proposes a self-healing system using multiple short microvascular channels in the through-thickness direction. First, the impregnation advantage of using this channel configuration is confirmed through delamination infiltration tests. Next, the feasibility of this channel configuration is evaluated by tensile tests and four-point bending tests. Double cantilever beam tests were then conducted to confirm its healing function. Finally, this system is applied to composite stiffened panels and the healing performance is evaluated using compression testing following panel indentation. The healing system almost fully recovered the original strength, confirming its high potential under practical conditions. Additionally, the weight reduction potential of the self-healing system was discussed through a strength comparison of specimens with different thicknesses.

　掛谷問題とは，面積0でありながら任意の方向の単位線分を含む不思議な集合（掛谷集合と呼ぶ）のHausdorff次元を問う問題である．この問題は2次元で解決されており，3次元以上では部分的な解決しかなされていない．本報告では最初に，掛谷集合のもととなった掛谷の針問題「単位線分を平面上で1回転させるのに必要な最小の面積はいくらか」という有名な問題とその解答を紹介する．これらは古くから知られる幾何の問題であるが，近年，掛谷問題が現代解析学，特にFourier解析に関する分野（実解析・調和解析学と呼ばれる）の諸問題と関わっていることがわかってきた．本報告の後半でこの諸問題に対する簡単な概説をする．
