The causes of drowning must dictate especially what we teach, content, and to a lesser degree, how we teach. Therefore, an project was conducted among Japanese university students in order to explore the relationship between swimming competency, students estimates of their competency, and their perception of the risk of drowning. Sixty five males and 48 females university physical education students enrolled at three institutions were the subjects of the study. The questionnaire consisted of a) perception of their ability, b) perception of their ability to perform these in open water and c) their perception of risk in five specific scenarios. Practical tests consist of seven aquatic skills. No significant differences were found in actual swimming-related abilities between male and female students, although more females than males did not complete the tests of: dive entry into pool (female 23%; male 11%), surface dive to 2m (female 33%; male 19%), and 100m swim on back (female 28%; male 9%). Similarly, no differences were found in self-estimated swimming abilities by gender. More females than males estimated higher risk of drowning for each of the 5 drowning scenarios that students were asked to estimate the personal degree of risk. This study found that male students tend to underestimate the potential dangers in the risk of drowning.

一部のエネルギーマネジメント規格において,セッション管理にXMPPが,また,別の規格においてはXMLのコンパクト符号化にEXIがそれぞれ検討されている.これらを組み合わせることで高効率なM2M通信を実現できる可能性があるが,現時点ではこれらの2つには仕様上の齟齬があり効率的に結合することは難しい.本稿では,この問題をEXI側の仕様改善により解決できることを示し,それによる副作用について述べる.

家庭内の機器に通信機能を搭載し各機器を協調制御させることにより,消費エネルギーの削減や創蓄エネルギーを組み合わせた最適化などに寄与するエネルギーマネジメントシステムが注目を集めている.エネルギーマネジメント向けの通信規格の1つであるZigBee SEP2.0のデータ形式として,XMLをコンパクトに符号化したEXIの採用が検討されている.EXI自体,メッセージサイズは小さいものの,符号化前や復号化後に自由度の高いXMLデータモデルを扱わなければならないため,メモリやCPUなどの資源に厳しい制約のある組込み機器へ単純に搭載するには困難がある.本研究では,直接EXIを操作可能にするXML-Less EXIを提案し,ZigBee SEP2.0で利用するデータ形式に対応した通信アダプタを試作後,その有効性について評価する.
