In recent years, SQUID (superconducting quantum interference device) technology has been developed for measuring the very low magnetic field generated from a human's physiology activity, and this technology is used for MEG (magnetencephalograph) and MCG (magnetcardiograph). In this way, the MEG and MCG have begun to be installed to the some hospitals as the medical devices. It is necessary to reduce the environmental magnetic field significantly, in order to measure the weak signals with high stability by using these devices. We developed and manufactured the magnetic shielding room for this purpose. In this paper, shielding performance of the magnetic shielding room at the low intensity and low frequency magnetic field is introduced.

テクニカルスキルの習熟のみでは防ぐことができないヒューマンエラーが生死に直結する航空 ・ 宇宙などの業界では,ヒューマンエラーの軽減を目的としたノンテクニカルスキルの訓練 ・ 評価の取り組みが大きな効果をあげている.一方,サイバーセキュリティの分野においては,未だヒューマンエラーによりインシデントが拡大する事案が散在しており,ノンテクニカルスキルに対する訓練 ・ 評価も十分ではない.そこで本稿では,航空 ・ 宇宙分野などで蓄積されたノウハウをベースに,セキュリティインシデント対応に適した新たなノンテクニカルスキルマップを作成する.また,提案したノンテクニカルスキルマップをサイバー演習等に応用させ,ノンテクニカルスキルの評価を実現する方法について検討する.

In a virtual weightless environment, pointing and modeling tasks were conducted to examine subjects'orientational skills. Subjects who wore a head-mounted display in a reclining chair moved from one end to the other end in several routes that were made by three or four modules that were connected by cubical modules, and pointed to the start point and made the experienced route by a scale model. Analyses of the results show the ability of spatial orientation varies with such variables as the number of bends, the number of embedding planes and the number of planes with respect to the body posture. Subjects who miss the tasks have a tendency not to take the change of the direction of their body axes into account.

The Japan Aerospace Exploration Agency (JAXA) established a research program to study an advanced space suit in 2007. The concept of the advanced space suit JAXA is developing is quite different from that of the space suit currently used on the International Space Station (ISS). By using Japanese high-performance polymer materials for the advanced space suit, the author expects to be able to develop a high-performance space suit that is equal or superior to the space suits the US and Russia developed. The author therefore considers the applicability of high-polymer materials for the advanced space suit in this report.

In Part 1, a simulation system was developed to examine human spatial orientation in a virtual weightless state. By conducting experiments in several routes of connected modules, we found some relevant variables for spatial cognition errors. Part 2 clarifies the causes of spatial cognition errors by the similar experiments using more complicated routes. The results showed the errors were able to be explained by two causes. One cause was that subjects did not recognize the rotation of the frame of reference, especially more often when they turned in pitch direction rather than in yaw. The other cause was that subjects were incorrect in the place, the direction, and the sequence of turns.
