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.

Recently, enrollments in nursery schools have become higher and higher. This is largely due to the social progress of women, with the increasing number of working mothers. Additionally, the number of three-generation households is decreasing. Nursery schools are traditionally low-rise structures, with a playground, but deregulation of the law now allows for the placement of nursery schools in middle floors of high-rise buildings. In Japan, the ages of nursery school students are generally from infancy to five-years old, which means that they can't evacuate the premises by themselves during a fire, so we must research ways to evacuate them safely. And the scheme of planning safe evacuations from buildings has not been sufficiently researched, so we have investigated the practice of fire drills and have interviewed teachers and students of nursery schools. The following is what we have learned: (1)Characteristics of evacuation ;drills of nursery schools: Students evacuate in class groups, lead by their teachers, who provide the indications. Time is needed for evacuation preparation (setting up strollers, gathering infants and preparing to carry them out, and giving instructions regarding exiting, etc., ) and before starting evacuation, and time for confirming the numbers of students, and waiting time is needed when they are evacuating, so these times must be considered in the calculation of evacuation time. (2)The characteristics of evacuation abilities of nursery school students : Infants (up to one-year old), and students who can't easily walk by themselves must be carried by a nurse or other adults, which makes evacuation movements and management after evacuation more manageable. Two-year-old students are able to walk alright on their own but cannot sufficiently grasp the situation. It's difficult to follow the teachers' instructions, so a lot of assistances are need. Children aged three and over can, of course, walk even better, and can grasp the severity of a fire. But they tend to walk more slowly as they feel frightened in cases when they are at earlier age, or they have to take an escape route that they are not familiar with. In order to shorten evacuation time, older students should evacuate first, as they can walk faster than younger students, thus their escape time won't be hindered by slower evacuees. (3)Notes of buildings that include a nursery school: Regarding the situation of using stairways for evacuation, there are many points of concern regarding the safety of children. Because there are many dangerous points related to stairways, such as the fact that stairways often arouse fear in younger students during emergency evacuation, and as a result they walk more slowly. Consequently, older students try to pass the younger, slower students. Especially in cases when a nursery school is on a middle floor of a multi-use building, there is a possibility that confusion is caused among the evacuating children who walk slowly, along with their teachers, as evacuating people from other facilities mix with people evacuating from the nursery school. Thus, having a dedicated set of stairs for children is better. In addition, nursery schools that are in existing buildings that were not designed to accommodate nursery schools, have higher handles and the height of steps rise. (4)Decreasing evacuation route length: Due to the fact that nursery school students' bodies and minds are not fully developed, their circumstances during a fire are more severe than those for adults. Thus, nursery schools should be on lower floors of buildings or should have their own buildings. Also the distance from the rooms to the temporary evacuation place should be as short as possible

本年度は昨年度の継続として、東大寺文書の帳簿類を収集・検討するとともに、『鎌倉遺文』に収録されている帳簿類の検討を行った。荘園の帳簿を総括的に論じるために、昨年の検討によって手懸かりを得た東大寺領の河上荘など、いくつかの荘園を取り上げた。河上荘では中世後期にはほぼ同じ書式の三斗米の収納帳簿が継続して用いられている。これは収納担当者(納所)が前任者の帳簿を引き継いで、担当年度の帳簿を作成するためであると思われる。このような帳簿様式の継続は、他にもあった可能性が高い。しかしとくに当荘は寺僧による管理が行われ、納所が毎年交替することが、かえって帳簿様式の画一性を高めたのではないかと思われる。また寺僧の管理は平安時代以来の伝統であると考えられること、作職の宛行などもそれを裏付けると思われることなど、当荘の性格を考える上での手懸かりを得た。また当荘に関係して残された多数の売券の検討が必要であることが分かった。当荘の売券については、すでに先行研究があるが、見落された文書もあるため、改めて検討する必要がある。典型的な検注帳のほかに、寺領経営のために作られた種々の坪付類についても考察を広げた。その一つとして東大寺の華厳会免田に関する史料を整理するなかで、赤袈裟著用に関する未紹介の史料を見出した。これは一一世紀末期・一二世紀初期における東大寺の興隆を明らかにするための興味深い史料と思われるため、史料紹介を兼ねた原稿を作成中である。

約1年の間に5人の覚醒剤乱用者グループの全員にみられた非A非B型急性肝炎例を経験した.これらの症例は注射器を共用し覚醒剤の静脈注射するといういわゆる“回し打ち”を行い,いずれも急性肝炎の発症を認めた.覚醒剤乱用と肝炎発症の関連について検討した結果,通常のB型,非B型急性肝炎に比べ潜伏期の長いことが推察された.回復期に行った肝生検像は,慢性活動性肝炎の所見であった,覚醒剤による弊害は現在大きな社会問題となっており,これによるB型肝炎の報告は散見されるが,非A非B型肝炎の報告は本邦では文献上みあたらず興味ある集団発症例と思われる.

The purpose of this research was to explore the influence on user's behavior by conditions of location. The analysis of the cafe user as “The Third Place” can be understood by observation research. The Third Place proposed by Ray Oldenburg means originally the social surroundings separate from the two usual social environments of home and the workplace, but the cafe in Japan advertise as third place meaning private working spots. By grasping the influence on user's behavior in the cafe through not only the Third Place was mainly conversation proposed by Oldenburg but private working in the cafe, it was cleared that the conditions of location and the ratio of property have effect on actions of use as the Third Place.

To provide data necessary for modeling turbulent mixing between subchannels in a nuclear fuel rod bundle, three experiments were made in series for equilibrium two-phase flows, in which net mass exchange does not occur between subchannels for each phase. The first one was the measurement of turbulent mixing rates of both gas and liquid phases by a tracer technique, using air and water as the working fluids. Three kinds of vertical test channels consisting of two subchannels were used. The data have shown that the turbulent mixing rate of each phase in a two-phase flow is strongly dependent on flow regime. So, to see the relation between turbulent mixing and two-phase flow configuration in the subchannels, the second experiment, flow visualization, was made. It was observed in slug and churn flows that a lateral inter-subchannel liquid flow of a large scale is caused by the successive axial transit of large gas bubbles in each subchannel, and the turbulent mixing for the liquid phase is dominated by this lateral flow. To investigate a driving force of such large scale lateral flow, the third experiment, the measurement of an instantaneous pressure differential between the subchannels, was made. The result showed that there is a close relationship between the liquid phase mixing rate and the magnitude of the pressure differential fluctuation.
