Réalité virtuelle et santé des personnes âgées institutionnalisées. Vers un EHPAD 2.0 ?

Virtual reality (VR) is used in general health care: prevention, physical medicine, chronic and acute pain, quality of life in palliative care, and in psychiatry: anxiety, depression, addiction, psychosis. Our objective is showing VR using among elderly people in French retirement home. Virtual reality is showing efficacy as distraction, anti-pain, tranquillising, antidepressant methods. It should be an answer to many elderly health problems. VR is easy to use, with low side effects. Non-drug treatments among elderly people are recommended. Used as complementary or alternative medicine, VR must be shaped for using with old and fragile people in retirement home.     

语篇阅读理解中人物性格模型的建构

采用实时窗口阅读技术,通过操纵特征段落性质和屏蔽段落长度两个变量,探讨人物性格模型在语篇阅读中的建构和影响因素。在研究所用材料中,特征段落描述能反映主人公性格的典型行为或不能反映其性格的一般行为,使其与目标句分别形成冲突或无关关系,考察读者能否利用这些内隐式的行为描述建构人物的性格模型。同时,改变屏蔽段落长度,形成局部或整体联贯两种条件,考察不同联贯类型的影响作用。结果发现：在不论整体还是局部联贯条件下,读者均能利用内隐的行为描述建构人物性格模型,并能应用该模型预期人物的后续行为。     

Effects of pH on the rate of aggressive display for mirror image reinforcement in siamese fighting fish (Betta splendens)

A hypothesis suggesting that fluctuations in hydrogen ion (pH) intensity may suppress the rate of aggressive display in Betta splendens was offered. The effect of pH upon the rate of ring swimming for aggression-releasing mirror image presentation was therefore investigated under pH intensities of 5.0, 7.0, and 9.0 in a steady-state design. The results indicated no significant variation in the rate of response over pH levels. Two possible mechanisms of pH resistance are discussed.     

The influence of a pedestrian countdown display on pedestrian behavior at signalized pedestrian crossings

Pedestrian behavior has been a subject of surveys carried out at two signalized pedestrian crossings, in the city of Doboj (BIH, Republic of Srpska). The analysis is made on the basis of video recordings, and includes behavior at pedestrian crossings, in various conditions (two locations, different vehicle flows, with or without a countdown display). The analysis also includes the distribution of illegal crossings (at the pedestrian red light) of different categories of pedestrians (gender, age), before and after the installation of a pedestrian countdown display, at two different pedestrian crossings. The results of the study have shown that a countdown display reduces statistically significantly the total number of violators, regardless of its location and traffic flow. However, this reduction is not the same at various categories of pedestrians (male, female, elderly, young people). The influence of the display has been particularly dominant at the pedestrian crossing located outside the centre of the city, with the smaller intensity of traffic. Children pedestrians do not accept the behavior in accordance with the countdown display in case of a reduced intensity of traffic, at a pedestrian crossing located in the backstreet. A countdown display does not statistically significantly change the distribution form of the number of offences during the red light for pedestrians, regardless of the pedestrian environment. However, there is a statistically significant difference in certain intervals (during the first and last 4 s) in the total distribution, as well as in the categories (female pedestrians, children). A countdown display does not reduce the overall number of “slow” pedestrians, but the impact on certain categories of “slow” pedestrians (gender/children), as well as on pedestrian violators, per age categories, varies depending on the location and traffic flow at an intersection.     

The effects of gender differences on the usability of automotive on-board navigation systems – A comparison of 2D and 3D display

This study integrated gender with the user interface of automotive on-board navigation systems to analyze whether gender differences or 2D (2 dimensional) vs. 3D (3 dimensional) display affect the interface usability of an on-board car navigation system (CNS). An experimental design was adopted for collecting data from three tasks – locating points, planning routes, and searching polygons – each emphasizing a different aspect of way-finding. The participants reported their subjective usability via the System Usability Scale after each trial. Study results show that gender, the CNS interface the subject used, and a combination of both predict the usability of an on-board CNS. This study’s results provide a clearer understanding of whether manufacturers should develop interfaces that fit a CNS 2D or 3D display based on gender.
