An Empirical Evaluation Of User Satisfaction With A School Nursing Information System
The adoption of a school nursing information system is considered one of the most efficient ways in which to document health records as well as monitor health conditions electronically. However, despite the importance of computerized health records in school nursing practice, few studies have examined user satisfaction of a school nursing information system. The aim of this study is to investigate the critical factors effecting school nursesâ satisfaction with a school nursing information system Utilizing a survey approach, questionnaires are distributed to nurses working in a primary or high school which introduces a new school nursing information system. The findings show several factors, including perceived usefulness, perceived of ease of use, training and workload are significant with user satisfaction. These results suggest that school nursing information system designers should comprehensively understand usersâ demands and perceptions about the system, which will further facilitate user satisfaction, decrease their workload, and ultimately enhance job performance

Applying the Resilience to the Community Development in Taiwan
In 1999, the Shishui community in Nantou County, Taiwan was severely damaged by the 921 earthquakes, with many houses collapsing and community facilities suffering unprecedented damage. In late 2001, a community development association was established, and with the efforts of residents, the community was awarded the title of Classic Rural Area by the government in 2007, becoming a nationally recognized leisure agriculture demonstration base. However, with the subsequent reduction of external resources, continuous loss of internal talents, and operational dysfunction of community organizations, the Shishui community eventually stagnated. How can we evaluate the community\u27s resilience in this situation? This study takes the Shishui community as its research field, integrates expert and scholar research on community resilience, constructs the elements of Shishui community development resilience through in-depth interviews with community residents, and analyzes Shishui community resilience indicators using the Fuzzy Delphi Method (FDM), with five main dimensions: sustainable development capacity, organizational leadership capacity, financial management capacity, community cohesion, and network resource capacity. Then, using the Similarity-based Importance-Performance Analysis (SBIPA) method, the study analyzes the evaluations of Shishui community residents on the satisfaction and importance of each resilience indicator. Finally, a total of 18 issues that residents consider important but have not yet reached the expected level of performance are identified, such as community resources and mechanisms to support young people returning to their hometowns and fair distribution of community resources by community organizations, which will become important directions for future community governance improvement
Cosmic positron and antiproton constraints on the gauge-Higgs Dark Matter
We calculate the cosmic ray positron and antiproton spectra of a gauge-Higgs
dark matter candidate in a warped five-dimensional
gauge-Higgs unification model. The stability of the gauge-Higgs boson is
guaranteed by the H parity under which only the Higgs boson is odd at low
energy. The 4-point vertices of HHW^+W^- and HHZZ, allowed by H parity
conservation, have the same magnitude as in the standard model, which yields
efficient annihilation rate for . The most dominant annihilation
channel is followed by the subsequent decays of the
bosons into positrons or quarks, which undergo fragmentation into antiproton.
Comparing with the observed positron and antiproton spectra with the PAMALA and
Fermi/LAT, we found that the Higgs boson mass cannot be larger than 90 GeV, in
order not to overrun the observations. Together with the constraint on not
overclosing the Universe, the valid range of the dark matter mass is restricted
to 70-90 GeV.Comment: 13 pages, 3 figure
Measuring the latency of cloud gaming systems
Cloud gaming, i.e., real-time game playing via thin clients, relieves players from the need to constantly upgrade their computers and deal with compatibility issues when playing games. As a result, cloud gaming is generating a great deal of interest among entrepreneurs and the public. However, given the large design space, it is not yet known which plat-forms deliver the best quality of service and which design elements constitute a good cloud gaming system. This study is motivated by the question: How good is the real-timeliness of current cloud gaming systems? To ad-dress the question, we analyze the response latency of two cloud gaming platforms, namely, OnLive and StreamMy-Game. Our results show that the streaming latency of On-Live is reasonable for real-time cloud gaming, while that of StreamMyGame is almost twice the former when the StreamMyGame server is provisioned using an Intel Core i7-920 PC. We believe that our measurement approach can be generally applied to PC-based cloud gaming platforms, and that it will further the understanding of such systems and lead to improvements
Understanding the performance of thin-client gaming
AbstractâThe thin-client model is considered a perfect fit for online gaming. As modern games normally require tremendous computing and rendering power at the game client, deploying games with such models can transfer the burden of hardware upgrades from players to game operators. As a result, there are a variety of solutions proposed for thin-client gaming today. However, little is known about the performance of such thin-client systems in different scenarios, and there is no systematic means yet to conduct such analysis. In this paper, we propose a methodology for quantifying the performance of thin-clients on gaming, even for thin-clients which are close-sourced. Taking a classic game, Ms. Pac-Man, and three popular thin-clients, LogMeIn, TeamViewer, and UltraVNC, as examples, we perform a demonstration study and determine that 1) display frame rate and frame distortion are both critical to gaming; and 2) different thin-client implementations may have very different levels of robustness against network impairments. Generally, LogMeIn performs best when network conditions are reasonably good, while TeamViewer and UltraVNC are the better choices under certain network conditions. I
NOVA, a Noncommutative-ring Based Unbalanced Oil and Vinegar Signature Scheme with Key-randomness Alignment
In this paper, we propose a noncommutative-ring based unbalanced oil and vinegar signature scheme with key-randomness alignment: NOVA (Noncommutative Oil and Vinegar with Alignment). Instead of fields or even commutative rings, we show that noncommutative rings can be used for algebraic cryptosystems. At the same or better level of security requirement, NOVA has a much smaller public key than UOV (Unbalanced Oil and Vinegar), which makes NOVA practical in most situations. We use Magma to actually implement and give a detailed security analysis against known major attacks
A Simple Noncommutative UOV Scheme
In this paper, we propose a simple noncommutative-ring based UOV signature scheme with key-randomness alignment: Simple NOVA, which can be viewed as a simplified version of NOVA[48]. We simplify the design of NOVA by skipping the perturbation trick used in NOVA, thus shortens the key generation process and accelerates the signing and verification. Together with a little modification accordingly, this alternative version of NOVA is also secure and may be more suitable for practical uses. We also use Magma to actually implement and give a detailed security analysis against known major attacks
Par-4 Links Dopamine Signaling and Depression
SummaryProstate apoptosis response 4 (Par-4) is a leucine zipper containing protein that plays a role in apoptosis. Although Par-4 is expressed in neurons, its physiological role in the nervous system is unknown. Here we identify Par-4 as a regulatory component in dopamine signaling. Par-4 directly interacts with the dopamine D2 receptor (D2DR) via the calmodulin binding motif in the third cytoplasmic loop. Calmodulin can effectively compete with Par-4 binding in a Ca2+-dependent manner, providing a route for Ca2+-mediated downregulation of D2DR efficacy. To examine the importance of the Par-4/D2DR interaction in dopamine signaling in vivo, we used a mutant mouse lacking the D2DR interaction domain of Par-4, Par-4ÎLZ. Primary neurons from Par-4ÎLZ embryos exhibit an enhanced dopamine-cAMP-CREB signaling pathway, indicating an impairment in dopamine signaling in these cells. Remarkably, Par-4ÎLZ mice display significantly increased depression-like behaviors. Collectively, these results provide evidence that Par-4 constitutes a molecular link between impaired dopamine signaling and depression
