Germany became old aged society faster than other countries, which gave the central government great burden, because the old people need national care system. Year by year national budget increase very sharply to pay medical service for old generation. German government has found as solution model "Pflegevermsicherung (PV: Long Term Aged Insurance)" in 1995 for the first time in the world, which contains medical service and social welfare service. This law aims to allow the old to live self reliable and self determinitive life. The major services of "Pflegevermsicherung" go along with "Krankenversicherung" The care givers of PV are central and local government, insurant company, private care giver. Care takers can get medical and social welfare services withour consideration of age. All disabled patients who have functional problemes to move can be supported by government. The standards of recipients are first, second and third levels. The systems of receiving long aged insurance begin by application of payment of "Long Term Aged Insurance" The insurance rate is 1.7% of all revenues of care takers. The old people allows to live most independently. This has lowerd the financial burden, diversified the care takers, and increased the role of the family.
Fertile women evaluate male bodies as more attractive, regardless of masculinity
Year: 2018

Ovulatory cycle shifts in women's mate preferences have been documented for several physical and behavioral traits. Research suggests that, at peak fertility, women tend to prefer men with characteristics that reflect good genes for short term sexual relationships. However, existing findings have been criticized for methodological flexibility and failing attempts to replicate core results. In a large N =157) pre registered, within subject study spanning two ovulatory cycles, we investigated cycle shifts in women's mate preferences for masculine bodies. Using a large set of natural stimuli, we found that when fertile, women's ratings of male bodies increased for sexual as well as for long term attractiveness. Both effects were partially mediated by the estradiol to progesterone ratio. Furthermore, moderation analyses revealed that both shifts were only evident in women in relationships, but not in singles. Contrary to previous findings, male masculine traits did not interact with cycle phase to predict attraction, indicating that women's preferential priorities do not shift. Taken together, our results do not support women's mate preference shifts, as assumed by the good genes ovulatory shift hypothesis, but are consistent with shifting motivational priorities throughout the cycle. Implications of these results for female estrus theories and methodological recommendations for future research are discussed.
Graph embedding based approach for detecting group shilling attacks in collaborative recommender systems
Venue: Knowl. Based Syst.
Year: 2020

Over the past decade, many approaches have been presented to detect shilling attacks in collaborative recommender systems. However, these approaches focus mainly on detecting individual attackers and rarely consider the collusive shilling behaviors among attackers, i.e. a group of attackers working together to bias the output of collaborative recommender systems by injecting fake profiles. Such shilling behaviors are generally termed group shilling attacks, which are more harmful to collaborative recommender systems than traditional shilling attacks. In this paper, we propose a graph embedding based method to detect group shilling attacks in collaborative recommender systems. First, we construct a user relationship graph by analyzing the user rating behaviors and use a graph embedding method to obtain the low dimensional vector representation of each node in the user relationship graph. Second, we employ the k means+ clustering algorithm to obtain candidate groups based on the generated user feature vectors. Finally, we calculate the suspicious degree of each candidate group according to the attack group detection indicators and use the Ward's hierarchical clustering method to cluster the candidate groups according to their suspicious degrees and obtain the attack groups. The experimental results on the Amazon and Netflix datasets show that the proposed method outperforms the baseline methods in detection performance.
Caracterisation hydrochimique des eaux embouteillees au Maroc
Year: 2016

Depuis le 20eme siecle, l'embouteillage des eaux a connu une expansion spectaculaire dans le monde. L'augmentation de la production des eaux embouteillees est associee aux developpements socio economiques des societes permettant l'acces a des eaux de qualite gustative meilleure en generale que les eaux du robinet. Au Maroc, trois types d'eau embouteillee potable sont reconnues l'eau de table (ET) d'origine quelconque, l'eau de source (ES) et l'eau minerale naturelle a propriete therapeutique (EM) Bien que leur qualite soit controlee, l'expansion de l'agriculture engendre un risque de contamination des aquiferes par les nitrates et phosphates. Huit eaux provenant de la zone du Rif et du Moyen Atlas rattachees a differentes conditions geologiques, 6 EM, 3 ES, ont ete analysees afin de verifier leur qualite affichee, 6 ET ont aussi ete analysees. Les resultats montrent une qualite chimique en bonne concordance et l'absence de contamination anthropique evolutive. Si la mineralisation des eaux s'est averee faible, la plupart des EM et ES montre une durete elevee. La variabilite des facies chimiques observes, de HCO3 Ca2+ a Cl Ca2+/Na+ est interpretee en fonction du contexte geologique et mineralogique local et les processus de dissolution associes ainsi que les apports profonds possibles par les failles.
Designing a Logic Model to Inform Montessori Research
Venue: Journal of Montessori Research
Year: 2019

Montessori education has a long history, but its recent growth in American public schools has led to increased interest in research efforts, particularly in exploring the potential of the Montessori experience to moderate the effects of poverty and in gathering data to evaluate public investment in Montessori schools. To assist research efforts, this paper introduces a comprehensive visual model, or logic model, that depicts the core components, underlying assumptions, and intended outcomes of the Montessori approach. Logic modeling, which results in a visual representation depicting the connections among a program's inputs, primary activities, and outcomes, is often used in program planning and research to provide a common framework from which to work. Developed over a 3 year period by a collaborative group of experienced Montessori researchers and practitioners, the Logic Model for Montessori Education presented in this paper is a valuable tool for researchers with the potential to lay a foundation across disciplines for future research that is both rigorous and systematic in its measurement of Montessori processes and outcomes.
Optimized Computation Offloading Performance in Virtual Edge Computing Systems Via Deep Reinforcement Learning
Venue: IEEE Internet of Things Journal
Year: 2019

To improve the quality of computation experience for mobile devices, mobile edge computing (MEC) is a promising paradigm by providing computing capabilities in close proximity within a sliced radio access network (RAN) which supports both traditional communication and MEC services. Nevertheless, the design of computation offloading policies for a virtual MEC system remains challenging. Specifically, whether to execute a computation task at the mobile device or to offload it for MEC server execution should adapt to the time varying network dynamics. This paper considers MEC for a representative mobile user in an ultradense sliced RAN, where multiple base stations (BSs) are available to be selected for computation offloading. The problem of solving an optimal computation offloading policy is modeled as a Markov decision process, where our objective is to maximize the long term utility performance whereby an offloading decision is made based on the task queue state, the energy queue state as well as the channel qualities between mobile user and BSs. To break the curse of high dimensionality in state space, we first propose a double deep {Q} network (DQN) based strategic computation offloading algorithm to learn the optimal policy without knowing a priori knowledge of network dynamics. Then motivated by the additive structure of the utility function, a {Q} function decomposition technique is combined with the double DQN, which leads to a novel learning algorithm for the solving of stochastic computation offloading. Numerical experiments show that our proposed learning algorithms achieve a significant improvement in computation offloading performance compared with the baseline policies.
Promocion de la autonomia y comprension de la identidad cultural en estudiantes de secundaria
Year: 2019

El presente trabajo de investigacion tiene como proposito contribuir al analisis y reflexion sobre el papel que juega el docente y su practica pedagogica en la promocion de la autonomia para la comprension de la Identidad Cultural. El diseno de la investigacion es cuasi experimental, donde se evaluo si la percepcion de la autonomia esta relacionada con la comprension de la identidad cultural en 20 estudiantes (13 mujeres y 7 hombres) entre 12 y 17 anos, de grado 9o, y una maestra de 43 anos, en una institucion educativa pubica de la ciudad de Cali Colombia. El apoyo a la autonomia se promovio a traves del uso intencional de lenguaje no controlador, oportunidad de eleccion y promocion de la relevancia a lo largo de una secuencia didactica que aborda la identificad cultural. El apoyo a la autonomia fue evaluado a traves de una pauta de observacion sobre los Comportamientos Instruccionales de la profesora (Reeve y Jang, 2006) y la pauta de observacion CLASS (Pianta, LaParo y Hamre, 2008) la percepcion de la autonomia se evaluo a traves de la Escala de Percepcion de la Autonomia (Reeve, Nixon y Hamm, 2003) que los estudiantes diligenciaron al final de cada sesion de clases mientras que la comprension de la identidad cultural se abordo a traves de un autorrelato y fue valorado a traves de una rubrica. Se encontro que la docente favorecio la autonomia a traves de sus interacciones con los estudiantes y que estos mostraron percepciones de alta autonomia y baja frustracion. Se concluye que la promocion de la autonomia promueve la comprension de la identidad cultural, esta ultima evidenciada en los cambios cualitativos y cuantitativos significativos en los desempenos de los estudiantes.

Pedagogical implications for improving body image and attitudes toward obesity through physical education.
Year: 2015

The aim of this study is to provide an overview of research into school curricula regarding body image and attitudes toward obesity and its relationship with physical activity to show the different trends and propose future considerations and pedagogical implications in this area. These implications are formulated through a teaching unit containing seven sessions on body image, self esteem and values, diet, physical activity, media, fashion trends, and emotions. This unit is developed for the fourth year of secondary. The proposal implemented in the school would be addressed through a socio critical model of health oriented physical education (PE) Prevention is the ideal treatment for obesity and schools are appropriate contexts to inform and educate about healthy habits such as physical activity, sport and eating, as well as to promote a positive body image (BI) and eradicate, as far as possible, the negative attitudes toward obesity.

Year: 2016

The main objective of this thesis is to investigate metal alloys as phase change material (PCM) for thermal energy storage (TES) applications. In particular, This work consists to analyze and characterize a set of binary and ternary metal alloys based on different compositions of Mg Al Zn mixtures, in order to identify new eutectic and peritectic compositions with adequate melting temperatures combined with appropriate thermophysical properties for their use as PCM storage media at high temperature for concentrated solar power (CSP) and industrial waste heat recovery applications among others. The first stage of this experimental work consists on synthesis of the selected metal alloys by using different routes of preparation. When the materials are synthesized a complete structural analysis is conducted by combining different techniques such as X ray diffraction (XRD) and scanning electron microscopy (SEM) The second stage of this work is to determine the most relevant thermophysical properties of these materials in this field such as the melting temperature, the heat capacity, the latent heat, the thermal conductivity, among others. The third stage is to investigate the long term thermal stability of the studied PCM by accelerated thermal cycling tests. The final stage consists to investigate the compatibility study between the selected alloys and different containment materials in order to identify the most suitable stainless steels that can be used in the construction of TES unit.
Evolution of wireless sensor networks towards the Internet of Things: A survey
Venue: SoftCOM 2011, 19th International Conference on Software, Telecommunications and Computer Networks
Year: 2011

Wireless Sensor Networks (WSNs) are playing more and more a key role in several application scenarios such as healthcare, agriculture, environment monitoring, and smart metering. Furthermore, WSNs are characterized by high heterogeneity because there are many different proprietary and non proprietary solutions. This wide range of technologies has delayed new deployments and integration with existing sensor networks. The current trend, however, is to move away from proprietary and closed standards, to embrace IP based sensor networks using the emerging standard 6LoWPAN/IPv6. This allows native connectivity between WSN and Internet, enabling smart objects to participate to the Internet of Things (IoT) Building an all IP infrastructure from scratch, however, would be difficult because many different sensors and actuators technologies (both wired and wireless) have already been deployed over the years. After a review of the state of the art, this paper sketches a framework able to harmonize legacy and new installations, allowing migrating to an all IP environment at a later stage. The Building Automation use case has been chosen to discuss potential benefits of the proposed framework.
A review of the use of virtual reality head mounted displays in education and training
Venue: Education and Information Technologies
Year: 2017

In the light of substantial improvements to the quality and availability of virtual reality (VR) hardware seen since 2013, this review seeks to update our knowledge about the use of head mounted displays (HMDs) in education and training. Following a comprehensive search 21 documents reporting on experimental studies were identified, quality assessed, and analysed. The quality assessment shows that the study quality was below average according to the Medical Education Research Study Quality Instrument, especially for the studies that were designed as user evaluations of educational VR products. The review identified a number of situations where HMDs are useful for skills acquisition. These include cognitive skills related to remembering and understanding spatial and visual information and knowledge; psychomotor skills related to head movement, such as visual scanning or observational skills; and affective skills related to controlling your emotional response to stressful or difficult situations. Outside of these situations the HMDs had no advantage when compared to less immersive technologies or traditional instruction and in some cases even proved counterproductive because of widespread cybersickness, technological challenges, or because the immersive experience distracted from the learning task.
Distinguishing Between Spiritual Distress, General Distress, Spiritual Well Being, and Spiritual Pain Among Cancer Patients During Oncology Treatment.
Venue: Journal of pain and symptom management
Year: 2017

Spiritual distress is present in approximately 25% of oncology patients.  We examined the extent to which this measure is identical to a variety of other measures, such as spiritual well being, spiritual injury, spiritual pain, and general distress.  Structured interview of oncology outpatients over 12 months, approached nonselectively. The presence or absence of spiritual distress was compared against spiritual pain and two spiritual well being tools: Functional Assessment of Chronic Illness Therapy Spiritual Well Being 12 Item Scale (FACIT Sp 12) and the Spiritual Injury Scale (SIS) We also examined whether a general distress visual analogue scale sufficed to identify spiritual distress. Other questions concerned demographic and clinical data.  Of 416 patients approached, 202 completed the interview, of whom 23% reported spiritual distress. All measures showed significant correlation (receiver operating characteristic, area under the curve: SIS 0.79; distress thermometer [DT] 0.68; FACIT Sp 12 0.67) yet none were identical with spiritual distress (sensitivity/specificity: SIS 64%/79% spiritual pain 72%/76% DT 41%/76% FACIT Sp 12 57%/72% Of the FACIT Sp 12 subscales, only peace correlated with spiritual distress. A significant predictor of spiritual distress was patients' self evaluation of grave clinical condition (odds ratio 3.3; 95% CI 1.1 9.5) Multivariable analysis of individual measure items suggests an alternative three parameter model for spiritual distress: not feeling peaceful, feeling unable to accept that this is happening, and perceived severity of one's illness.  The DT is not sufficient to identify spiritual distress. The peace subscale of FACIT Sp 12 is a better match than the measure as a whole. The SIS is the best match for spiritual distress, although an imperfect one.
Het onafhankelijkheidssyndroom: Een cultuurgeschiedenis van het naoorlogse Nederlandse zorgstelsel
Year: 2015

De ideologische dimensie van de verzorgingsstaat wordt veelal afgedaan als irrelevant, of, erger nog, als bekend verondersteld. Door discussies in naoorlogse artsenbladen in kaart te brengen en die in een context te plaatsen van bredere politieke en maatschappelijke debatten, thematiseert dit onderzoek de ideologische dimensie van de verzorgingsstaat en ontmaskert het de mythe dat collectieve solidariteit zijn kernwaarde zou zijn. Dit proefschrift beschrijft hoe in naoorlogs Nederland een verzorgingsstaat ontstond vanuit het streven om iedere burger toegang te geven tot goede zorg. In Nederland ging de overtuiging dat mensen recht hebben op sociale zekerheid, altijd gepaard met het uitgangspunt dat alle burgers ook zelf verantwoordelijkheid moeten kunnen dragen voor de zorg voor hun eigen gezondheid en welzijn. Dat betekende dat rechten en verantwoordelijkheden tegen elkaar moesten worden afgewogen, met als consequentie een overheid die terughoudend was om de voor eigen verantwoordelijkheid noodzakelijke vrijheid van haar burgers te beperken. Onder deze tegenstelling ligt echter een diepere, gedeelde waarde: die van individuele onafhankelijkheid. Het bestrijden van afhankelijkheden was in veel gevallen de prikkel om het zorgstelsel te (willen) hervormen al riep elke hervorming weer nieuwe vormen van afhankelijkheid op.
Statistical Methods of Causal Effects in Social Sciences
Year: 2009

People before stuck to the apparent relation between objects to infer the causal effects.After applying the manipulation and control means to research,they have made great progress but also faced more difficulties.In 1970s,Rubin pointed out that the nature of the causal effects is the issue of counter fact and that some statistical methods used to guarantee the confounding variables is independent from subject assignment.Now,these methods are extensively used to analyze the observable data.The present paper introduces three statistical methods for causal effects inference and explains how to apply the propensity score to data analysis.
