In product development, a method of cost cutting is required for manufacturing prototypes. Based on our recent research, we propose a low-cost prototyping system for subjective evaluation using a virtual environment. We call this method “Virtual prototyping using Kansei evaluation”. We determine the surface roughness and orientation, surface reflectance and transmission of surface-finished papers. Measured data are analyzed using directional statistics and subjective evaluation of surface-finished papers. As a result, we obtain the surface roughness and orientation, as well as the directional intensity of the surface-finished papers. We described the Kansei structures of subjective evaluation “thin”, “weighty”, “airy”, “hard”, and “tender” from kurtosis and luminance of surface reflections and transmissions. Using these techniques, it is possible to create surface appearances for virtual prototyping.

Virtual reality training is considered as an effective intervention method of stroke patients, and the virtual reality system for therapeutic rehabilitation has emphasized the cognitive factors to improve walking function. The purpose of current study was to investigate the effect of virtual reality training with cognitive load (VRTCL) on walking function of chronic stroke. Chronic stroke patients were randomly assigned to the VRTCL group (11 patients, including 5 men; mean age, 60.0 years; post-stroke duration, 273.9 days) or control group (11 patients, including 2 men; mean age, 58.6 years; post-stroke duration, 263.9 days). All subjects participated in the standard rehabilitation program that consisted of physical and occupational therapies. In addition, VRTCL group participated in the VRTCL for 4 weeks (30 min per day and five times a week), while those in the control group participated in virtual reality treadmill training. Walking function under single (walking alone) and dual task (walking with cognitive tasks) conditions was assessed using an electrical walkway system. After the 4-week intervention, under both single and dual task conditions, significant improvement on walking function was observed in VRTCL and control groups (P < 0.05). In addition, in the dual task condition, greater improvement on walking function was observed in the VRTCL group, compared with the control group (P < 0.05). These findings demonstrated the efficacy of VRTCL on the walking function under the dual task condition. Therefore, we suggest that VRTCL may be an effective method for the achievement of independent walking in chronic stroke patients.

Background: The Fukushima Pregnancy and Birth Survey was launched to monitor pregnant mothers’ health after the Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Plant (NPP) accident. Several lines of investigations have indicated that a disaster impacts maternal mental health with childbirth. However, there is no research regarding mental health of mothers with fetal loss after a disaster. In this report, we focus on those women immediately after the Great East Japan Earthquake and Fukushima NPP accident and discuss their support needs.Materials and Methods: Data regarding 61 miscarriages, 5 abortions, and 22 stillbirths were analyzed among the women who were pregnant at the time of the accident in the present study. We used a two-item case-finding instrument for depression screening, and compared the childbirth group with the fetal loss groups. We also analyzed mothers’ opinions written as free-form text.Results: Among the three fetal loss groups, the proportion of positive depression screens was significantly higher in the miscarriage and stillbirth group than in the childbirth group. Mothers’ opinions were grouped into six categories, with pregnancy-related items being most common, especially in the miscarriage and stillbirth groups.Conclusion: A higher proportion of Fukushima mothers with fetal loss, especially those with miscarriage and stillbirth, had depressive symptoms compared to those who experienced childbirth. Health care providers need to pay close attention to this vulnerable group and respond to their concerns regarding the effects on their fertility.

エビデンスの概念は、わが国の教育分野では、一般的に知られているとは言い難いが、昨今、「エビデンスに基づく政策」(evidence-based policy)という言葉が政策を論議する文献等で多く散見されるようになってきている。本論では、このような背景にあって、第一にコクラン共同計画やキャンベル共同計画が基本とする、ランダム化比較試験(RCT)の系統的レビュー(メタ・アナリシス)で産出される厳密な定義でのエビデンスを中心に、産出、普及、活用の上で生じる課題を明らかにする。第二に広義の科学的根拠という意味で、経済協力開発機構(OECD)が、近年「エビデンスに基づく政策」という言葉を用いて政策提言を積極的に行ってきている背景を人的資本論に基づきながら論じる。そして、最後に教育におけるエビデンスに基づく政策についての方向性を示唆する。

2011年3月11日の東北地方太平洋沖地震(Mw 9.0)によって東北日本弧の応力場が大きく変化し,誘発地震が多発している.2011年4月11日の福島県浜通りの地震(Mw 6.6)は,これまでに発生した最大の内陸地殻内誘発地震である.この地震に伴って,従来推定活断層と認定されていた湯ノ岳断層や井戸沢断層の西側トレースに沿って明瞭な正断層型の地震断層が出現した.地震断層の長さはともに約15 kmであり,最大上下変位量は前者が約0.9 m,後者が約2.1 mである.井戸沢断層の西側トレースのトレンチ掘削調査では,ひとつ前の活動時期が12500〜17000年前と求められ,869年の貞観地震の際に活動した痕跡は見出せなかった.2011年4月の福島県浜通りの地震は,海溝型超巨大地震に誘発されて活動する内陸活断層が存在することを示すと共に,変位地形が不明瞭な推定活断層もそのような状況下で大地震を発生させ得ることを示した.

The lesser mouse deer (Tragulus javanicus) is one of the most primitive ruminants. Skulls of lesser mouse deer were measured to evaluate their growth. The age was estimated from the eruption and attrition of molars on the mandible. A total of 95 specimens was divided into five age groups, and the growth pattern in each sex was established for some measurements. The relative growth coefficients were calculated for the head and body length and several parts of the cranium and mandible against the profile length. Sexual dimorphism could not be found on the skull in any age group except for measurements related to the upper canine. However, females showed a higher value in head and body length in the oldest group. This feature was consistent with an interpretation of mouse deer society as monogamous. Growth was more rapid in length than in width. Various statistical analyses showed that the visceral cranium related to masticatory facility was much better developed than the neurocranium. However, observations on the shape of the mandible ramus and of the premolars implied that the masticatory function was not suitable for taking roughage. This speculation agreed with previous reports on the feeding habits and digestive organs of the mouse deer.

Power transmission systems with timing belt are often used in various machines because of their simple mechanism and easy treatment. However, the diagnosis for those transmission system has not fully established. This paper discusses self-failure diagnosis for a timing belt transmission system using tension-differential-type torque sensor (TDT sensor). A tension pulley is usually incorporated into a part of the transmission system, so that the system can maintain a proper tension during operation. Since such a tension pulley receives force directly from the timing belt, it is expected that the diagnosis of the timing belt can be done with much high S/N ratio and thus with high reliability. Based on this idea, the authors designed a TDT sensor available for a timing belt application, and explored a diagnosis algorithm detectable not only for a timing belt with V-crack but also for a timing belt with blinding at a tooth. Through a number of experiments, we verified the effectiveness of the proposed algorithm and also found an interesting behavior of the sensor signals which is not expected.

SAR interferometry is widely used for dense measurements of surface displacements caused by earthquakes, but the method cannot be applied if displacements are too large. The near-epicentral area of the Iwate–Miyagi Nairiku Earthquake in 2008 is an inapplicable case. Therefore, we applied photogrammetry to measure surface displacement caused by the earthquake. The maximum horizontal and vertical displacements were found to be 5.3 m and 2.9 m, respectively. We recognized three lines where displacement changes abruptly. The displacement distribution is like that of a reverse fault along the first line (A–B), an east-rising fault along the second line (F–G–H; west of line A–B), and a left-lateral fault along the third line (B–C; between line A–B and line F–G–H). The earthquake source fault reaches or approaches the ground surface at line A–B, with slippage decreasing toward the ground surface. The fault-like large surface deformation found north of the Aratozawa Dam is on the first line. The fault-like deformation was caused by the motion of the earthquake source fault, and the relative displacement of the fault-like deformation was enlarged by local causes. A gravitational mass movement found north of the fault-like deformation is one cause. Because the width of the rising area is small, only 3.5 km, at the southwestern side of line B–C, the slip of the earthquake source fault is mainly distributed near the ground. Line F–G–H suggests the existence of a geological structure that causes the abrupt changes of vertical displacement without a horizontal displacement, for example a high-angle fault.  We assumed: (1) the slip on the main fault is distributed only in a shallow area at the southern part of the main fault and only in a deep area at the northern part; and, (2) the difference of slip caused two lateral faults between southern and northern parts. The assumption qualitatively explains many observation results, such as why there is an abrupt change of horizontal displacement along line B–C and why line F–G–H has a convex part to the east. We found a correlation between the occurrence of large landslides and abrupt changes of displacement, in other words large surface strain. The following mechanisms are possible causes of the correlation: (1) stress from surface strain increased large landslides; (2) faults (not only the main fault) may exist under the focused areas, rupture of faults caused both large surface strain and large seismic motion, and seismic motion induced large land slides. We also found that landslides and slope failures occurred densely over the slipping area on the main fault, based on the assumptions in the previous paragraph. Because photogrammetric measurements need interactive observations, we could avoid observations on possible embanking areas. Because photogrammetry allows intensive measurements at interesting areas, we revealed a two flexure-like distribution of vertical displacement. Therefore, photogrammetry is an effective method for measuring surface displacement caused by an earthquake.
