副第5指屈筋はヒトの足底で観察出来る小型の破格筋で, 本筋の起源については古くから多くの論説のある興味深い筋である。著者らは日本人成人遺体10体(男6体, 女4体)を検索し, 4体・6体側例の副第5指屈筋を認めた。体側別出現頻度は両側2体, 左側1体および右側1体で, 性別出現頻度は男3体, 女1体であった。また, 1例は副第5指屈筋, 副第4指屈筋および副第3指屈筋の共存する非常に稀な破格であった。破格筋の支配神経については1例のみ外側足底神経の筋枝を確認することが出来た。

In pregnant women, non-obstetric surgery should be performed during an appropriate period to prevent congenital anomaly and to avoid miscarriage or premature labor. The second trimester of pregnancy is better for surgery because the risk of maternal, anatomical and physiological changes is lower. Neurotoxicity and the teratogenicity of anesthetic agents should be considered. In addition, blood flow to the placenta must be maintained during the surgery.  We performed anesthesia for an 18-week pregnant woman who required a radical neck dissection because of the metastasis of tongue cancer. She was 29 years old, 160 cm tall, and weighed 46.1 kg. Before the induction of anesthesia, the patient was placed in a left half-lateral position by placing towels under the right lower back to avoid supine hypotension syndrome, as the patient complained of a sense of abdomen distension while in a supine position. Her face was twisted to the right to secure a surgical field. General anesthesia was induced with intravenous propofol, atropine, fentanyl and remifentanil. Two milliliters of 4% lidocaine was sprayed on the subglottic area and the glottis for topical anesthesia. A tracheal tube (ID, 6.0 mm) was intubated orally using McGRATH. The anesthesia was maintained with the inhalation of 1.5%-1.7% sevoflurane in oxygen (Fio2, 0.4), as sevoflurane may be less neurotoxic to a fetus than isoflurane or desflurane. Ephedrine was administered intravenously to maintain blood flow to the placenta when the blood pressure decreased. The operation and anesthesia were completed uneventfully.  After the operation, the obstetrician performed an ultrasonography examination to confirm that the fetus had good fetal movement and a normal pulse.

With the depletion of global energy resources, saving energy has become an important aspect in design of energy consuming equipment. Hence, this paper deals with an optimal time of operation of a manipulator which minimizes the energy dissipated in the actuators. When the manipulator is operated in a vertical plane, the system is highly non-linear due to gravity and an analytical solution can not be found. Therefore, the system is first linearized around various equilibrium points and the existence of an optimal time is investigated theoretically. The theoretical results resemble the simulation of the non-linear system except for a slight difference in the optimal time. The theoretical results and simulations show that an optimal operating time exists when the first link of the manipulator traverses the stable equilibrium point and that it does not exist when the first link traverses the unstable equilibrium point. Finally, a non-linear optimization method is applied to ascertain the accurate optimal time of operation.

シフトJISコード (JIS X 0208) の日本語文書圧縮法について提案する. 日本語文字は通常2バイト固定長で表現され, 文書中では連続して出現する傾向にある. そこで, 出現頻度の高い2バイト文字を辞書配列に登録し, これらを1バイトで短縮表現する方法を提案する. 圧縮率については, 既存の圧縮法と組み合わせることで良好な圧縮率を達成した.
