Design and realization of a network security model
The security of information is a key problem in the development of network technology. The basic requirements of security of information clearly include confidentiality, integrity, authentication and non-repudiation. This paper proposes a network security model that is composed of security system, security connection and communication, and key management. The model carries out encrypting, decrypting, signature and ensures confidentiality, integrity, authentication and non-repudiation. Finally, the paper analyses the merits of the model. (author abst.
Academical and Research Wiimote Applications
IADIS MULTI CONFERENCE ON COMPUTER SCIENCE AND
INFORMATION SYSTEMS 2008
Amsterdam, The Netherlands
JULY 22 - 24, 2008This paper proposes the employment of the Wii Remote controller, better known as Wiimote, as an useful tool for
educators and researchers. The quick development on fields such as Wireless Sensors and Actuators Networks or Hybrid
Systems, and their applications, requires engineers with a solid knowledge in these areas. To achieve this goal the
Wiimote becomes a great alternative to other options due to its great variety of analog and digital components, for a very
low price, and the good documentation about it existing in Internet. As will be seen in this paper, the possible academical
and research uses of the Wiimote are almost endless and cover many interesting problems in control engineering
Reconnecting whānau: Pathways to recovery for Māori with bipolar disorder
While Māori are known to experience a higher burden of mental health and addiction problems compared to non-Māori (Baxter, 2008), little exploratory research has been conducted into Māori experiences of bipolar affective disorder. Bipolar disorder is at times regarded as a “life sentence”, with little hope of recovery. The recovery- focused mental health literature, however, argues wellness is achievable for even the most intractable conditions (Lapsley, Nikora, & Black, 2002; Mental Health Commission, 2001). The aim of this research was to gather information about the experiences of Māori who were diagnosed with bipolar affective disorder. Interviews were conducted with 22 Māori wāhine (women) and tāne (men), and using thematic analyses, themes relevant to their life stories were uncovered. This research sought to contribute to the realisation of Māori potential by explicitly shifting from deficit- focused frameworks to a focus on systemic factors that influenced Māori wellbeing. Highlights were that whānau (participants) who were connected with friends, partners and family were motivated to achieve wellness and to stay well
Subjective wellbeing, sense of humor and psychological health in hemodialysis patients
Objective: To investigate the relationship between satisfaction with life in general, sense of humor, and anxiety, depression and stress with subjective happiness in chronic kidney disease patients undergoing hemodialysis. Material and Methods: A cross-sectional and correlational study was developed in two units of the Diaverum dialysis clinic and one hospital unit, with 183 chronic kidney disease patients undergoing hemodialysis. An instrument was used to characterize the sociodemographic and clinical profile of the sample (age, gender, nationality, education, occupation, marital status, dialysis sessions length, presence of hypertension and diabetes): the subjective happiness scale; the satisfaction with life in general; depression, anxiety and stress scale 21; and multidimensional sense of humor scale. Inferential procedures included Spearman correlation coefficients, and multiple linear regression adjusting to age, marital status, professional activity and diabetes.Results: Subjective Happiness was positively correlated with satisfaction with life in general, and the three dimensions of Sense of Humor. Nevertheless, subjective happiness was negatively correlated with stress / anxiety and depression. Satisfaction with life in general, humor production and social use of humor, and attitude towards humor had a positive relationship with subjective happiness. However, depression had a negative relationship with subjective happiness. Conclusions: Higher levels of subjective happiness were associated with higher levels of satisfaction with life in general, and sense of humor, however they were also associated with lower levels of depression in patients undergoing hemodialysis
Teaching Compassion in Prison: A Key to Learning
In a project with long-term prisoners at HMP Dumfries, Scotland, tutors and students explore the notion and application of compassion, focusing in particular on the ways in which understanding compassion enables learning – not just the learning of academic subjects but also of interpersonal skills and emotional intelligence. The project highlights the benefits of teaching a so-called extracurricular subject, at the same time as revealing its centrality to learning in the first place. A lack of adequate teaching time in prison, and the fact that compassion is not considered a core subject in education, are both cited as obstacles in consolidating the work of the project. The benefits of teaching compassion - emotional, intellectual and spiritual - was made clear through written and verbal student feedback. Three short workshops highlighted the enormous potential in developing and establishing compassion as both subject and practice in prison education. It is hoped that practitioners and researchers will support the expansion of this work throughout prisons
The SPHERE data center: a reference for high contrast imaging processing
The objective of the SPHERE Data Center is to optimize the scientific return
of SPHERE at the VLT, by providing optimized reduction procedures, services to
users and publicly available reduced data. This paper describes our motivation,
the implementation of the service (partners, infrastructure and developments),
services, description of the on-line data, and future developments. The SPHERE
Data Center is operational and has already provided reduced data with a good
reactivity to many observers. The first public reduced data have been made
available in 2017. The SPHERE Data Center is gathering a strong expertise on
SPHERE data and is in a very good position to propose new reduced data in the
future, as well as improved reduction procedures.Comment: SF2A proceeding

The remote banking become one of the main channels for bank services distribution. The Internet expansion of the Bulgarian banks is at its beginning. The showed results are based on the Internet research, which has aimed to describe actual picture of Bulgarian banks present in Internet.Banks, Internet, Online services, Online banking, E-commerce, Bulgaria
Human/Humanity, Consciousness and Universe: Informational Relation
From the perspective of the Informational Model of Consciousness elaborated and reported recently on the basis of the last
discoveries of the quantum mechanics and astrophysics, the meeting horizon between some ancient coherent empirical
models of the humanity and our modern scientific results is analyzed. These results are discussed in terms of information,
as a central axis relating the universe, the human and inter-humanity connections, and consciousness as an informational
tool for the exploration of the reality. Bringing into discussion the relevant recent discoveries of quantum mechanics (Higgs’
boson, disembodiment of information from the physical particles), and matter/information properties near the black holes,
it is reinforced the concept of information as one of the fundamental constituent of matter and of our universe, showing that
information is actually the base fabric of matter structures, living structures and universe. The huge quantity of dynamic
information engaged in the living structures, particularly in the human organism, necessary to maintain the life’s functions
and to allow the adaptation requirements, differentiates the living from non-living entities. It is shown that consciousness,
human and universe cannot be really understood if it is not introduced on the panoramic scene a new player – dark matter,
with more than 20% contribution, besides more than 70% dark energy and only 5% observable matter from the matter total
quantity. It is shown also that the Informational Model of Consciousness, consisting in an architecture of seven cognitive
centers, converges with the ancient models of chakras, of etheric body and aura concepts, with dual Taoist concepts of
universe and human body, contributing with answers to the “mind-body”, “nature or nurture” problems and even to Qualia
“hard” problem, and supporting the Jung’s concepts on the mind. Finally, some questions are addressed to the quantum
mechanics, concerning the retro-causal effect and non-locality principle
User Perceptions of Smart Home IoT Privacy
Smart home Internet of Things (IoT) devices are rapidly increasing in
popularity, with more households including Internet-connected devices that
continuously monitor user activities. In this study, we conduct eleven
semi-structured interviews with smart home owners, investigating their reasons
for purchasing IoT devices, perceptions of smart home privacy risks, and
actions taken to protect their privacy from those external to the home who
create, manage, track, or regulate IoT devices and/or their data. We note
several recurring themes. First, users' desires for convenience and
connectedness dictate their privacy-related behaviors for dealing with external
entities, such as device manufacturers, Internet Service Providers,
governments, and advertisers. Second, user opinions about external entities
collecting smart home data depend on perceived benefit from these entities.
Third, users trust IoT device manufacturers to protect their privacy but do not
verify that these protections are in place. Fourth, users are unaware of
privacy risks from inference algorithms operating on data from non-audio/visual
devices. These findings motivate several recommendations for device designers,
researchers, and industry standards to better match device privacy features to
the expectations and preferences of smart home owners.Comment: 20 pages, 1 tabl
