スマートウォッチを用いた歩行者ナビゲーションシステムのHMI について

本稿ではモバイル/ウェアラブル/インフラ協調型歩行者ナビゲーションシステムの実現に向けてスマートウォッチにおける HMI(Human - Machine Interface)について，既存研究・情報の整理と実験による HMI の評価を行っている．まずスマートウォッチ利用の有無を含め，既存の歩行者ナビゲーションシステムにおいて使用される案内情報とその提示方法，画面操作によるシステムへの入力について整理を行っている．次にスマートウォッチが持つ他のデバイスにはない特徴から，スマートウォッチの歩行者ナビゲーションシステムにおける役割を明確化し，その役割に応じた HMI を設計するために被験者実験を行っている．被験者実験の結果からスマートウォッチで提示する案内情報とその提示方法を決定している．以上より，スマートウォッチを使用した歩行者ナビゲーションシステムに関する知見を獲得している． In this paper, we classify existing research of pedestrian navigation system including smartwatch on HMI (Human-Machine Interface) and evaluate HMI by experiments in order to realize a mobile / wearable / infrastructure collaborative operation based pedestrian navigation system. First, we classify the navigation information and the presentation method used in existing pedestrian navigation systems, including the use of smartwatches, and input to the system by screen operations. Next, we clarify the role of the smartwatch in the pedestrian navigation system considering the characteristic features of the smartwatch, and do a subjective experiments to design an HMI according to the role. From the results of the subjective experiments, the navigation information to be presented on the smart watch and the presentation method are determined. Consequently, the knowledge on pedestrian navigation system using smart watch are obtained.Copyright ©2020 by IEICE IE2019-87textapplication/pdftechnical repor

Feasibility Study of NMR Based Serum Metabolomic Profiling to Animal Health Monitoring: A Case Study on Iron Storage Disease in Captive Sumatran Rhinoceros (<i>Dicerorhinus sumatrensis</i>)

<div><p>A variety of wildlife species maintained in captivity are susceptible to iron storage disease (ISD), or hemochromatosis, a disease resulting from the deposition of excess iron into insoluble iron clusters in soft tissue. Sumatran rhinoceros (<i>Dicerorhinus sumatrensis</i>) is one of the rhinoceros species that has evolutionarily adapted to a low-iron diet and is susceptible to iron overload. Hemosiderosis is reported at necropsy in many African black and Sumatran rhinoceroses but only a small number of animals reportedly die from hemochromatosis. The underlying cause and reasons for differences in susceptibility to hemochromatosis within the taxon remains unclear. Although serum ferritin concentrations have been useful in monitoring the progression of ISD in many species, there is some question regarding their value in diagnosing hemochromatosis in the Sumatran rhino. To investigate the metabolic changes during the development of hemochromatosis and possibly increase our understanding of its progression and individual susceptibility differences, the serum metabolome from a Sumatran rhinoceros was investigated by nuclear magnetic resonance (NMR)-based metabolomics. The study involved samples from female rhinoceros at the Cincinnati Zoo (n = 3), including two animals that died from liver failure caused by ISD, and the Sungai Dusun Rhinoceros Conservation Centre in Peninsular Malaysia (n = 4). Principal component analysis was performed to visually and statistically compare the metabolic profiles of the healthy animals. The results indicated that significant differences were present between the animals at the zoo and the animals in the conservation center. A comparison of the 43 serum metabolomes of three zoo rhinoceros showed two distinct groupings, healthy (n = 30) and unhealthy (n = 13). A total of eighteen altered metabolites were identified in healthy versus unhealthy samples. Results strongly suggest that NMR-based metabolomics is a valuable tool for animal health monitoring and may provide insight into the progression of this and other insidious diseases.</p></div

Highly Arsenic-contaminated Areas in Bangladesh and Development of Multi Gravel Sand Filte

In Bangladesh, many arsenic mitigations have been conducted these 22 years since the first detection of As-contamination of groundwater in 1993. A DPHE/JICA report made clear the situation of arsenic mitigation in 2010. According to the report, 19 million people do not have access to any safety water options （SWOs） yet, and also 4.6 million people are still living where As-contaminated ratio is more than 80% but safe water coverage is less than 20%. It is the worst As-contaminated areas. The Asia Arsenic Network （AAN） had the chance to study the situations of As-mitigation and construct SWOs in some of these worst areas. There were many highly As-contaminated tube wells （As>0.5mg/L） with low Fe-concentrations. AIRP/GSF, used considerably in Bangladesh, can not be applied to these highly As-contaminated tube wells because that the iron concentratIon in tube well water needs to satisfy the condition of Fe/As>20. In order to supply safe water in the highly As-contaminated areas, an improved GSF （multi GSF） is now being developed. This paper describes the situations of highly As-contaminated areas and the improved GSF under development.othe
