The problem of water and electrolyte metabolism, an essential regulation in the living body of its internal environment, has been investigated by many researchers. In this paper, we have summarized our study concerned with the effects of thermal bath (plain water or hot spring) on the water and electrolyte metabolism. Also, some related changes in circulatory and endocrine systems were considered.Twelve young men were selected and series of comparative study before and after each bathing for 10 minutes duration at temperature of 40 to 43°C have been performed.I Water and electrolyte metabolism(1) Immediately after the bathing no change was observed in the total body water. The extracellular fluid and the plasma volume increased; hematocrit values were lowered, while the total blood water as well as the plasma water was both increased and the water content of blood corpuscles was decreased. This result was inferred to a replacement of body water from inside to outside of the cells.(2) The minute volume of urine voided immediately after the bathing showed a transient increase, whereas it was decreased after the period of bath and also less than the pre-bathing stage.(3) Plasma Na was lowered after the bathing, while K and Cl remained unchanged. Na content of blood corpuscles showed a rise and K was lowered. The same tendency has also been observed in the skeletal muscle.(4) Reabsorption of Na as well as excretion of K in the urine was slightly increased after the bathing.(5) There was a loss of electrolytes into sweat.(6) The permeability of Na24 across the capillary wall was increased during and immediately after the bathing.II Changes in circulatory and endocrine systems related with water and electrolyte metabolismAmong many changes induced by thermal bathing which may cause alteration in circulatory and endocrine systems, a rise of body temperature and an induced hyperfunction of adrenal glands were considered to play a major role in the whole processes.

折り紙に不慣れなユーザが、初見の教本と折り紙を見比べながら折り進めるのは困難である。そこで AR マーカを印刷した折り紙に拡張現実 (AR) を用いたアニメーションを重ねて表示することで、誰でも迷わずに折れる折り紙の製作指導支援システムを実装した。また、評価実験により支援システムの有用性を検証した。A user unfamiliar to origami can not compare the origami with textbook of the first look.We implemented the origami tutoring system that displayed the CG animation at the origami which was printed AR marker.We performed evaluation experiments and inspected the usefulness of the system.
