Preparing of therapeutic data for the foremost half incorporates operation, data storage and data sharing etc. Usual social services framework often wants the conveyance for restorative data to cloud which incorporates purchasers touchy information and cause correspondence. For intents and functions, restorative data sharing is basic and testing issue. Be that because it could, there has been protection worries as on the brink of home well-being information can be bestowed to those outsider servers, and to unapproved parties. To ensure the patient's authority over accessing their Personal Health Records (PHR), it is a promising strategy to cipher the PHR before reappropriating. However issues, as an example; danger of protection introduction, ability in key administration, adaptable access, and skillful client denial, have remained the foremost very important difficulties towards accomplishing fine-grained, typographically approved data gets to regulate. During this paper, we tend to propose a completely unique patient driven system and a set of parts for data gets regulate to PHR place away in semi confided in servers. To accomplish fine-grained and versatile data gets to regulate for PHR, we tend to influence Attribute based encryption coding (ABE) strategies to cipher each patient's PHR document. Distinctive in respect to past works in secure information redistributing, we tend to center on various data owner state of affairs, and gap the purchasers within the PHR frame-work into numerous securities areas that very lessens the key administration many sided nature for proprietors and purchasers transportable cloud let. A high-level of patient protection is ensured whereas by misusing multi-specialist ABE. Our commit to boot empowers dynamic modification of access strategies or record qualities, bolsters effective for the asking client/characteristic repudiation and break glass access below crisis things. Broad scientific and trial results as displayed that demonstrate the protection, ability, and productivity of our set up.

Information leakage and efficiency are the two main concerns of data sharing in cloud-aided IoT. The main problem is that smart devices cannot afford both energy and computation costs and tend to outsource data to a cloud server. Furthermore, most schemes focus on preserving the data stored in the cloud but omitting the access policy is typically stored in unencrypted form. In this paper, we proposed a fine-grained data access control scheme based on CP-ABE to implement access policies with a greater degree of expressiveness as well as hidden policies from curious cloud service providers. Moreover, to mitigate the extra computation cost generated by complex policies, an outsourcing service for decryption can be used by data users. Further experiments and extensive analysis show that we significantly decrease the communication and computation overhead while providing a high-level security scheme compared with the existing schemes.

Background Health care professionals (HCPs) are often patients’ first point of contact in what concerns the communication of the purposes, benefits, and risks of sharing electronic health records (EHRs) for nondirect care purposes. Their engagement is fundamental to ensure patients’ buy-in and a successful implementation of health care data sharing schemes. However, their views on this subject are seldom evaluated. Objective This study aimed to explore HCPs’ perspectives on the secondary uses of health care data in England. Specifically, we aimed to assess their knowledge on its purposes and the main concerns about data sharing processes. Methods A total of 30 interviews were conducted between March 27, 2017, and April 7, 2017, using a Web-based interview platform and following a topic guide with open-ended questions. The participants represented a variety of geographic locations across England (London, West Midlands, East of England, North East England, and Yorkshire and the Humber), covering both primary and secondary care services. The transcripts were compiled verbatim and systematically reviewed by 2 independent reviewers using the framework analysis method to identify emerging themes. Results HCPs were knowledgeable about the possible secondary uses of data and highlighted its importance for patient profiling and tailored care, research, quality assurance, public health, and service delivery planning purposes. Main concerns toward data sharing included data accuracy, patients’ willingness to share their records, challenges on obtaining free and informed consent, data security, lack of adequacy or understanding of current policies, and potential patient exposure and exploitation. Conclusions These results suggest a high level of HCPs’ understanding about the purposes of data sharing for secondary purposes; however, some concerns still remain. A better understanding of HCPs’ knowledge and concerns could inform national communication policies and improve tailoring to maximize efficiency and improve patients’ buy-in.

Businesses and corporations today break geographical boundaries and carry out business globally (Carlson & Perrewe, 1999). Business travel can be physically demanding and psychologically stressful, compromising the well-being of business travelers and the benefits of organizations. The present study examined how biopsychosocial factors, which are health concern, burnout, and social support, explained business travel stress among business travelers in Malaysia. We recruited 100 working adults (n = 63 men, n = 37 women) who traveled for business purposes from airports in Malaysia. Participants completed a series of questionnaires using the paper-and-pencil method. The mediation analyses showed that only burnout mediated the relationship between business travel and perceived stress. Specifically, the less intensely an individual traveled, s/he experienced a higher level of perceived stress; and this could be explained by the high level of burnout experienced. These findings have shed some light on how to deal with business travel stress at organizational and personal levels. Our findings suggested that organization-level interventions and policies should place an emphasis on employees who have to travel and in particular those who travel less intensively. Also, to provide support for business traveling employees, corporations should set up interventions and policies that aim to decrease burnout associated with business traveling.

Access Structures

Data sharing has become a key technology to break down data silos in the big data era. Ciphertext-policy attribute-based encryption (CP-ABE) is widely used in secure data-sharing schemes to realize flexible and fine-grained access control. However, in traditional CP-ABE schemes, the access structure is directly shared along with the ciphertext, potentially leading to users’ private information leakage. Outsourcing data to a centralized third party can easily result in privacy leakage and single-point bottlenecks, and the lack of transparency in data storage and sharing casts doubts whether users’ data are safe. To address these issues, we propose a blockchain-based CP-ABE scheme with partially hidden access structures (BCP-ABE-PHAS) to achieve fine-grained access control while ensuring user privacy. First, we propose an efficient CP-ABE scheme with partially hidden access structures, where the ciphertext size is constant. To assist data decryption, we design a garbled Bloom filter to help users quickly locate the position of wildcards in the access structure. Then, to improve storage efficiency and system scalability, we propose a data storage scheme that combines blockchain technology and the interplanetary file system, ensuring data integrity. Finally, we employ smart contracts for a transparent data storage and sharing process without third-party participation. Security analysis and performance evaluation show that the proposed BCP-ABE-PHAS scheme can preserve policy privacy with efficient storage and low computational overhead.

Competence of the pedagogues, their individual qualities, motivation, creativity, the desire to constantly develop their skills and grow, and the ability to share the best practices are the main factors of success in education. In view of this, assistance to a young teacher is given great importance, as well as favourable conditions for a career-building. According to the Lithuanian and foreign research, major and sustainable changes in the area of education are possible only when teachers themselves are engaged in the implementation of changes (Ingersoll, Smith, 2004; Kennedy, 2008; Tatto, 2007; Review of the Lithuanian Education System, 2013). It means, that teacher’s profession requiring high level responsibility and altruism is the central axis in creating well-being of the country (Watt, 2012; Taylor, 2006). Yet, in Lithuania, as well as in the entire Europe, there is still a problem of ageing teachers, and it becomes more and more topical, since the number of young people selecting profession of a pedagogue is continuously decreasing. Thus, we have to solve a complicated task – to motivate young people to select profession of a teacher. The Article analyses the factors in selecting pedagogical studies and their links with further selection of a profession. In pursuance of these goals, the research applied the methods of the literature and document analysis, a questionnaire survey and mathematical statistics. Quantitative research and questionnaire survey were carried out in March-April 2014. The research involved 117 respondents from 4 Lithuanian universities. The respondents were 2nd–4th year students: social pedagogues, special pedagogues and career education pedagogues. Pursuant to the research findings, selection of pedagogical studies was determined by the internal factors (interests, predisposition, values), the perceived value of social services, the possibility to be useful for the society), understanding of own teaching abilities depending on the acquired experience (e.g. delivered lessons, taking care of small children). The majority of respondents intended to relate their life to the selected profession of a pedagogue. Mainly these were the persons who have selected the studies as the first or one of the first priorities; selected the studies individually, inspired by this profession as calling and after gaining experience in school. The motives fostering connection of the career with the selected profession are also very important, e.g. desire to grow and take care of other people, quest for independence at work, used pedagogical practices, an interesting profession meeting the expectations and a desire to ensure successful future.

Image Management System

One of the most common tasks in a typical analysis lab is the recording of images. Many analytical techniques (TEM, SEM, and metallography for example) produce images as their primary output. Until recently, the most common method of recording images was by using film. Current PS/2R systems offer very large capacity data storage devices and high resolution displays, making it practical to work with analytical images on PS/2s, thereby sidestepping the traditional film and darkroom steps. This change in operational mode offers many benefits: cost savings, throughput, archiving and searching capabilities as well as direct incorporation of the image data into reports.The conventional way to record images involves film, either sheet film (with its associated wet chemistry) for TEM or PolaroidR film for SEM and light microscopy. Although film is inconvenient, it does have the highest quality of all available image recording techniques. The fine grained film used for TEM has a resolution that would exceed a 4096x4096x16 bit digital image.

Abstract. Conflict avoidance increases across the adult lifespan. This cross-sectional study looks at conflict avoidance as part of a mechanism to regulate belongingness needs ( Sheldon, 2011 ). We assumed that older adults perceive more threats to their belongingness when they contemplate their future, and that they preventively react with avoidance coping. We set up a model predicting conflict avoidance that included perceptions of future nonbelonging, termed anticipated loneliness, and other predictors including sociodemographics, indicators of subjective well-being and perceived social support (N = 331, aged 40–87). Anticipated loneliness predicted conflict avoidance above all other predictors and partially mediated the age-association of conflict avoidance. Results suggest that belongingness regulation accounts may deepen our understanding of conflict avoidance in the second half of life.
