Evacuation Ability of Residents and General Capability of Disaster Response System at Care Facilities for Elderly People

As a basic research on the evacuation safety of Korean residential facilities for the elderly population, this study surveyed the actual status of residents' evacuation ability and disaster coping system in welfare facilities for elderly people. Based on the on-site investigation of the long-term care grade , movement method, and observation of all residents, and the number of staff available for emergency correspondence at 7 care facilities for elderly people and 3 elderly care group residences , the residents' evacuation ability was assessed and correlated against long-term care grade and movement method. The study revealed notable difference in movement methods between care facilities for elderly people and elderly care group residences , and similarity of evacuation ability of the residents to that of surgery department in hospital wards. Additionally, it was found that, in case of fire at night, every employee in some facilities should evacuate 20 persons or more. To alleviate the burden on the staff, early fire detection and notification are regarded as important, and taking disaster prevention measures and adopting disaster prevention facilities in buildings to secure the safety of residents are urgent requirements .
La Bible et le destin du peuple noir : Essai de réflexion critique sur le mythe de la malédiction de Cham

Le monde noir en general et l'Afrique en particulier sont englues dans des difficultes qui ne laissent guere d'espoir. Cette impression que l'Afrique noire est dans l'impasse est resumee par un mot : l'afro-pessimisme. Ce mot resulte en partie d'une tradition mythique faconnee par une certaine lecture de la Bible : la malediction de Cham. De nos jours, ce mythe survit a travers les prejuges entretenus par certains medias, d'ou la tentation d'une interpretation fataliste de l'histoire du monde noir. Cet article a pour ambition de demontrer que les Noirs ne sont aucunement maudits et que leur avenir est entre leurs mains
Assessing Usability Testing for People with Dementia

This paper reports on a study which examines the value of several common usability testing protocols, methods and metrics when used to evaluate the usability of a new personalised reminiscence ‘app’. The app, called ‘Inspired’, is a bespoke app designed to support personalised reminiscence for people with dementia. The study focused on determining the value of commonly used methods for evaluating usability of apps designed for use by people with dementia and their caregivers. The study indicated that observation and recording of task completion rates and times produced the most reliable results. The think-aloud methodology was difficult for the people with dementia and did not produce any reliable data. Thinking-aloud whilst doing a task was perhaps a distraction since it requires a higher cognitive load. The systematic usability scale score which is derived from a post-test instrument is not reliable, as it had no association with the task completion times.
Strontium and Silicon Co-Doped Apatite Coating: Preparation and Function as Vehicles for Ion Delivery

New methods to improve the bone response to metallic implants are still emerging, ranging from surface modifications of the metal to coatings and drug delivery. One further development of coatings on implants is to incorporate bioactive ions in order to stimulate the bone response without the need of drug delivery. The aim of the current study is to prepare apatite coatings containing Sr and Si using a solution method, for the purpose of further optimising the bone response to metal implants. Titanium substrates were activated to induce the formation of coatings in modified PBS solutions. Soaking in PBS solutions with different concentrations of strontium and silicate at 37℃ or 60℃ produced coatings with different morphologies, thicknesses and compositions. Ion release experiments showed simultaneous release of Sr and Si from the coatings both in PBS and Tris-HCl. Analysis of the results using the Korsmeyer-Peppas model indicate that the release of ions from the coatings was a combination of Fickian diffusion and degradation of the coatings. This study shows that it is possible to coat Ti substrates with modified apatite with ion release functionality and thereby increase the possibilities for a tailored bone response in vivo.
Ideas of Four-Fermion Operators in Electromagnetic Form Factor Calculations

Four-fermion operators have been utilized in the past to link the quark-exchange processes in the interaction of hadrons with the effective meson-exchange amplitudes. In this presentation, we apply the similar idea of Fierz rearrangement to the electromagnetic processes and focus on the electromagnetic form factors of nucleon and electron. We explain the motivation of using four-fermion operators and discuss the advantage of this method in computing electromagnetic processes.
Improving conversational dynamics with reactive speech synthesis

The active exchange of ideas and/or information is a crucial feature of human-human conversation. Yet it is a skill that present-day ‘conversational’ interfaces are lacking, which effectively hampers the dynamics of interaction and makes it feel artificial. In this paper, we present a reactive speech synthesis system that can handle user’s interruptions. Initial results of evaluation of our interactive experiment indicate that participants prefer a reactive system to a non-reactive one. Based on participants’ feedback, we suggest potential applications for reactive speech synthesis systems (i.e. interactive tutor and adventure game) and propose further interactive user experiments to evaluate them. We anticipate that the reactive system can offer more engaging and dynamic interaction and improve user experience by making it feel more like a natural human-human conversation.
Implementation of counted layers for coherent ice core chronology

Abstract. A recent coherent chronology has been built for four Antarctic ice cores and the NorthGRIP (NGRIP) Greenland ice core (Antarctic Ice Core Chronology 2012, AICC2012) using a Bayesian approach for ice core dating (Datice). When building the AICC2012 chronology, and in order to prevent any confusion with official ice core chronology, the AICC2012 chronology for NGRIP was forced to fit exactly the GICC05 chronology based on layer counting. However, such a strong tuning did not satisfy the hypothesis of independence of background parameters and observations for the NGRIP core, as required by Datice. We present here the implementation in Datice of a new type of markers that is better suited for constraints deduced from layer counting: the duration constraints. Estimating the global error on chronology due to such markers is not straightforward and implies some assumption on the correlation between individual counting errors for each interval of duration. We validate this new methodological implementation by conducting twin experiments and a posteriori diagnostics on the NGRIP ice core. Several sensitivity tests on marker sampling and correlation between counting errors were performed to provide some guidelines when using such a method for future dating experiments. Finally, using these markers for NGRIP in a five-core dating exercise with Datice leads to new chronologies that do not differ by more than 410 years from AICC2012 for Antarctic ice cores and 150 years from GICC05 for NGRIP over the last 60 000 years.
W2F: A Weakly-Supervised to Fully-Supervised Framework for Object Detection

Weakly-supervised object detection has attracted much attention lately, since it does not require bounding box annotations for training. Although significant progress has also been made, there is still a large gap in performance between weakly-supervised and fully-supervised object detection. Recently, some works use pseudo ground-truths which are generated by a weakly-supervised detector to train a supervised detector. Such approaches incline to find the most representative parts of objects, and only seek one ground-truth box per class even though many same-class instances exist. To overcome these issues, we propose a weakly-supervised to fully-supervised framework, where a weakly-supervised detector is implemented using multiple instance learning. Then, we propose a pseudo ground-truth excavation (PGE) algorithm to find the pseudo ground-truth of each instance in the image. Moreover, the pseudo ground-truth adaptation (PGA) algorithm is designed to further refine the pseudo ground-truths from PGE. Finally, we use these pseudo ground-truths to train a fully-supervised detector. Extensive experiments on the challenging PASCAL VOC 2007 and 2012 benchmarks strongly demonstrate the effectiveness of our framework. We obtain 52.4% and 47.8% mAP on VOC2007 and VOC2012 respectively, a significant improvement over previous state-of-the-art methods.
Effect of math-specific self-efficacy on math literacy: Evidence from a Greek survey

Prior research has suggested a strong link between student-level psychological constructs such as self-efficacy and achievement in academics. In this study, we looked at the relationship between math self-efficacy and mathematics literacy using a large-scale survey from Greece. Our analytical results show that there is a strong association between math self-efficacy and math literacy among Greek high school students, and that this association persists even after controlling for student-level differences such as age, grade, gender, parental education, parental occupation, family wealth, cultural possessions, and availability of educational resources at home, and school-level differences such as school type, school size, student–teacher ratio, and school-level socioeconomic status.
Quercetin induces cell death by caspase-dependent and p38 MAPK pathway in EGFR mutant lung cancer cells

Objectives: The aim of this study was whether quercetin induces cell death by caspase and MAPK signaling pathway in EGFR mutant lung cancer cells Methods: PC-9 cells, EGFR mutant lung cancer cells, were treated various times and concentrations of quercetin and harvested and measured using MTT assay, DNA fragmentation, Western blotting, and FACS analysis. Results: Treatment with quercetin in PC-9 cells resulted in inhibition of cell growth through apoptosis. Quercetin-induced apoptosis was associated with caspase-dependent manner. Quercetin also significantly increased levels of phosphor-p38 and decreased levels of phosphor-ERK, indicating that quercetin induces p38 MAPK signaling pathway in PC-9 cells. Quecetin treatment also generated the release of cytochrome c in PC-9 cells; however, pretreatment with rotenone or z-LEHD-fmk, significantly attenuated quercetin-induced apoptosis. Conclusions: Our data indicate that quercetin exhibits EGFR mutant lung cancer effects through apoptosis by caspase dependent and mitochondrial pathway.
Volatility of secondary organic aerosol during OH radical induced ageing

Abstract. The aim of this study was to investigate oxidation of SOA formed from ozonolysis of α-pinene and limonene by hydroxyl radicals. This paper focuses on changes of particle volatility, using a Volatility Tandem DMA (VTDMA) set-up, in order to explain and elucidate the mechanism behind atmospheric ageing of the organic aerosol. The experiments were conducted at the AIDA chamber facility of Karlsruhe Institute of Technology (KIT) in Karlsruhe and at the SAPHIR chamber of Forchungzentrum Julich (FZJ) in Julich. A fresh SOA was produced from ozonolysis of α-pinene or limonene and then aged by enhanced OH exposure. As an OH radical source in the AIDA-chamber the ozonolysis of tetramethylethylene (TME) was used while in the SAPHIR-chamber the OH was produced by natural light photochemistry. A general feature is that SOA produced from ozonolysis of α-pinene and limonene initially was rather volatile and becomes less volatile with time in the ozonolysis part of the experiment. Inducing OH chemistry or adding a new portion of precursors made the SOA more volatile due to addition of new semi-volatile material to the aged aerosol. The effect of OH chemistry was less pronounced in high concentration and low temperature experiments when lower relative amounts of semi-volatile material were available in the gas phase. Conclusions drawn from the changes in volatility were confirmed by comparison with the measured and modelled chemical composition of the aerosol phase. Three quantified products from the α-pinene oxidation; pinonic acid, pinic acid and methylbutanetricarboxylic acid (MBTCA) were used to probe the processes influencing aerosol volatility. A major conclusion from the work is that the OH induced ageing can be attributed to gas phase oxidation of products produced in the primary SOA formation process and that there was no indication on significant bulk or surface reactions. The presented results, thus, strongly emphasise the importance of gas phase oxidation of semi- or intermediate-volatile organic compounds (SVOC and IVOC) for atmospheric aerosol ageing.
The Influence of Situational Variables on Brand Personality Choice

The goal of this research is to investigate whether or not consumers select brands (and their brand personality) based on two important situational variables: social visibility and situational involvement. An experimental study was conducted in which two hundred and thirty-nine respondents were randomly assigned to one of four situations and asked via a self-administered questionnaire to describe the beer, with regard to its brand personality, that they would purchase in that situation. Situations were either high or low in social visibility and high or low in situational involvement resulting in a 2 X 2 factorial design. Three-way interaction effects between the situational variables (i.e., situational involvement and social visibility) and an individual variable (i.e., brand loyalty) were discovered. The results indicate that depending on the situation and an individual’s brand loyalty, consumers will seek different types of brands (personality-wise). Thus, this research should help brand managers further understand how their brands are perceived and consumed.
In-Band Full-Duplex Architectures for Future 5 G Multi-Hop Networks

With regard to the forthcoming requirements for mobile services in 5G networks, several new technologies have recently become the focus of leading-edge research. One of those is in-band full-duplex communications. The idea is to simply employ the same frequency band to simultaneously transmit and receive information, allowing more spectrally efficient communications when compared to the traditional half-duplex or out-of-band full-duplex counterparts. By breaking a long-held assumption in wireless communications, in-band full-duplex may double the throughput or reduce by half the allocated bandwidth in future transmissions. Nevertheless, the self-inflected interference, that naturally arises, poses the major problem to the use of this technique, enhanced when in presence of system impairments. Therefore, this thesis aims to study self-interference suppression methods, in multi-hop relaying environments, and proposes different systems where it may contribute the most, focusing solely on the digital domain. Particularly, digital spatial suppression filters are studied, as well as feedback adaptive filtering is proposed for relay systems with multiple-input multiple-out (MIMO) antennas. Furthermore, the orthogonal properties of large-scale arrays are resorted to, such that an extra level of mitigation is achieved. In this case, the relay system energy efficiency is maximized by finding the optimal transmit powers, while maintaining a certain individual link quality. Finally, physical layer network coding (PLNC) is combined with bidirectional in-band full-duplex relaying, reducing the allocated resources down to the same of machine-to-machine communication. For this scenario, the effect of massive MIMO is likewise addressed, and an algorithm that maximizes the system total achievable rate is derived.
Association of Race and Ethnicity With Glycemic Control and Hemoglobin A1c Levels in Youth With Type 1 Diabetes

Key Points Question Is there evidence for racial/ethnic health inequity with respect to longitudinal patterns of glycemic control among youth with type 1 diabetes? Findings In a longitudinal cohort study of 1313 youths (aged <20 years) with type 1 diabetes, patients with black race or Hispanic ethnicity were at higher risk of being in the highest and most rapidly increasing hemoglobin A1c trajectory group over 9 years after diabetes diagnosis when compared with non-Hispanic white patients. These associations persisted only among male patients and those with diagnosis at age 9 years or younger. Meaning There is health inequity with regard to glycemic control, particularly among young nonwhite male patients and nonwhite youth diagnosed earlier in life.

We also demonstrate the effectiveness of the perceptually optimized viewport-based immersive video streaming strategy under network bandwidth constraint, using our proposed analytical quality models.
Review of Regulatory Policies on and Benefits of Herbal Medicine in the Philippines

Herbal products are the mainstay treatment among patients with limited access to conventional medicines and those seeking holistic modalities for health and wellness. Usage continues to increase globally with the growing engagement of science and technology in the scientific and sound development of herbal products. In the Philippines, legislative controls on herbal medicine were established through the creation of the Philippine Institute of Traditional and Alternative Health Care (PITAHC) which aims to include herbal medicine use in the national health care system. This paper aims to review the current regulatory policies on production, registration, promotion, and use of herbal medicines in the country. Current policies provide measures in regulating, implementing, and monitoring of herbal medicines from production to consumption stages. However, improvements based on provisions from international standards can be adopted to guarantee efficacy and safety for public use. Policies are still lacking regarding implications of long-term effects; efficacy on specific populations (i.e. children, elderly, pregnant women); and on potential interactions with other food and drugs. There is also a need to strengthen studies on the environmental determinants influencing the effectiveness of herbal products. Paucity on studies on cost-effectiveness of herbal medicines is further noted.
Multilingualism in Action: A Conversation Analytic View on how Children are Re-Voicing a Story in a French Second Language Learning Lesson

Our paper provides an empirically based perspective on the contribution of Conversation Analysis (CA) to our understanding of children’s second language learning practices in a multilingual classroom setting. While exploring the interactional configuration of a French second language learning activity, we focus our analytic lens on how five children and their teacher rely on multilingual resources (French, German, Luxemburgish, and Portuguese) in order to initiate and to improve the re-voicing of a story in French. Through a moment-bymoment (CA) video based analysis we can show how co-constructing the second language learning object involves various embedded linguistic and interactional competencies. We will point out how the participants engage in the re-voicing activity through their mutual orientation to each other’s language conduct. Effective second language learning becomes possible because the teacher’s student-directed talk provides opportunities for the children to provide oral narratives in a jointly constituted multilingually shaped interaction. Moreover, by offering insights into the interactional features (turn-taking system), CA allows us to visualize how the children’s second language learning practices are interrelated with the sequential structure of multilingual talk-in-interaction. Thus, in our case study we emphasize the fundamentally social nature of second language classroom talk.
