Real-Time Human Tracker Based on Location and Motion Recognition of User for Smart Home

The ubiquitous smart home provides an automatic home service via analysis of human and home contexts. It receives a lot of contexts from the human and the home environment, but the most important context is information about the human’s location and motion. In this paper, we present a real-time human tracker that detects human location and motion using cameras and predicts services in the ubiquitous smart home. We propose an algorithm that captures effective area from four network cameras in which human is detected and his position is estimated. To detect human motion, three kinds of images are used: IMAGE1: empty room image, IMAGE2: image of furniture and home appliances in the home, IMAGE3: image of IMAGE2 and the human. The system decides if specific furniture or home appliance is associated with the human by analyzing three images, and estimates human motion using a support vector machine (SVM). Human motion was recognized as four types: "lie down", "sit", "stand-up", and "walk". The human motion recognition is decided from the pixel number by the array line of the moving object using SVM. We evaluated each motion 1000 times. The average accuracy of all the motions was found to be 85.3%.
Comparison of HRM analysis and three REP-PCR genomic fingerprint methods for rapid typing of MRSA at a Brazilian hospital.

INTRODUCTION Infections caused by multidrug-resistant bacteria are increasingly common and represent a serious problem for public health. Staphylococcus aureus is one of the major agents of infections, and methicillin-resistant S. aureus (MRSA) has spread worldwide. The aim of this study was to phenotypically and genotypically characterize 55 MRSAs isolated in the University Hospital of Londrina, Paraná, Brazil, during 2010. METHODOLOGY Bacterial isolates were characterized based on their antimicrobial susceptibility profile, biofilm production capacity, and staphylococcal chromosome cassette mec (SCCmec) type. Determination of clonal groups was performed by polymerase chain reaction using the RW3A, JB1, and BOX A1R primers and high-resolution melting (HRM) analysis. RESULTS The majority of isolates harbored SCCmec type II. SCCmec III, characteristic of the Brazilian endemic clone, was observed in four strains. Only two isolates harbored SCCmec type IV, which is common in community-acquired MRSA strains. Most isolates also showed resistance to more than four of the tested antimicrobials, and 30 isolates exhibited the ability to produce biofilm. DNA polymorphism analysis showed a higher discriminatory power for the JB1 primer, but RW3A revealed several clonal groups of MRSA with similar genotypic and phenotypic characteristics. HRM analysis showed eight different sequence types. CONCLUSIONS These results are important for epidemiological studies involving MRSA infections.
HOW TO DEVELOP STRATEGIC LEADERSHIP IN HIGHER EDUCATION INSTITUTIONS

In a turbulent environment and difficult to predict, effective strategic leadership is the foundation of success in a strategic management process. The aim of this research was to analyze the dimensions of strategic leadership and how the dimensions influence of the strategic leadership. The research method used was a survey. The sample comprised 67 respondents; Chairman of the Study Programs of graduate (Strata 1) and Postgraduate (Strata 2) of Economics and Management College in Jakarta. Data were analyzed using Partial Least Square (PLS). The result shows that from the three dimensions of strategic leadership, the dimension which gives the biggest contribution to strategic leadership is to be a strategic expert (strategist), then is as change agent, and the last is as a visionary leader. The implication of this results is to improve the effective strategic leadership, a leader have to be a strategic expert, then to be change agent and should be able to create clear and relevant visions and mission of the organization.
Development of wireless controller area network using low cost and low power consumption ARM microcontroller for solar car application

In this paper, a wireless controller area network (CAN) was developed using low cost microcontroller. The system is low cost and low power consumption for CAN application in order to receive data such as velocity, temperature and batteries power from Maximum Power Point Tracking (MPPT). A programming was written for the microcontroller to receive data from MPPT and sent it out through wireless transceiver for a chase car to determine whether the solar car is in the optimum condition. However the microcontroller receives data at a baud rate of 1Mbps need to down rates to 9600bps due the maximum limitation of the wireless transceiver. This may cause losses of data during transmission and as such an interval is introduced between CAN messages by using interrupt function.
Treatment with valacyclovir, famciclovir, or antiretrovirals reduces human herpesvirus‐8 replication in HIV‐1 seropositive men

Human herpesvirus‐8 (HHV‐8) replication is a key factor in Kaposi sarcoma, primary effusion lymphoma, and Castleman disease pathogenesis. In vitro data suggest that antivirals inhibit HHV‐8 replication, but little data exist in humans. Daily oropharyngeal swabs were analyzed from HIV/HHV‐8 dually infected men enrolled in three previous clinical trials of valacyclovir and famciclovir for HIV‐1 and/or HSV‐2 suppression. Fifty‐eight participants contributed 6,036 swabs. HHV‐8 was detected in 1,128 (19%) of 6,036 swabs, including 618 (21%) of 2,992 on placebo, 323 (15%) of 2,221 on valacyclovir, and 187 (23%) of 823 on famciclovir. After adjusting for baseline HIV viral load and highly active antiretroviral therapy (HAART) use, an 18% reduction in HHV‐8 shedding frequency (IRR 0.822; P = 0.011) was found in participants on valacyclovir and a 30% reduction (IRR 0.700; P < 0.001) on famciclovir. HAART was associated with an 89% (IRR 0.129; P = 0.048) reduction in HHV‐8‐shedding. Neither antiviral nor antiretroviral therapy was associated with decreased HHV‐8 quantity. Valacyclovir and famciclovir were associated with modest but significant reductions in HHV‐8 oropharyngeal shedding frequency. In contrast, HAART was a potent inhibitor of HHV‐8 replication. Studies of whether antiviral therapy in combination with ART will prevent HHV‐8‐associated disease appear warranted. J. Med. Virol. 83:1696–1703, 2011. © 2011 Wiley‐Liss, Inc.
N-acetyl transferase 2 and cytochrome P450 2E1 genes and isoniazid-induced hepatotoxicity in Brazilian patients.

SETTING Isoniazid (INH) is related to the development of hepatotoxicity in some patients. OBJECTIVE To investigate the role of N-acetyl transferase 2 (NAT2) and cytochrome P450 2E1 (CYP2E1) in the hepatotoxicity of patients treated with INH in an Amazonian Brazilian population. DESIGN Patients undergoing anti-tuberculosis treatment were investigated. Hepatotoxicity was defined as an increase of more than three times the upper limit of normal in serum alanine aminotransferase levels after treatment. NAT2 genotypes were identified by sequencing, whereas CYP2E1 alleles were detected using polymerase chain reaction based methods. RESULTS Of the 270 individuals included in the study, 18 (6.7%) developed drug-related hepatotoxicity. A high association was found between slow acetylators and hepatotoxicity, particularly with regard to allele *5. The adjusted risk of developing hepatotoxicity was significant in individuals carrying two slow acetylation alleles (P = 0.036, OR 3.05, 95%CI 1.07-8.64). In all of the CYP2E1 markers examined, wild homozygous genotypes were more prevalent in subjects with hepatotoxicity than in controls; however, the difference was not statistically significant. Joint evaluation of the genes revealed a high risk of developing hepatotoxicity in slow acetylators with CYP2E1 wild alleles (adjusted OR 4.26; 95%CI 1.47-12.37, P = 0.008). CONCLUSIONS Large-scale screening for NAT2 and CYP2E1 genotypes can prove useful in predicting the risk of adverse effects.
Analysis of the force characteristic on the armature of inductive coil launcher and trigger strategy

The inductive coil launcher utilizes the theory of magnetic coupling between the driving coil and the armature. The armature is accelerated when the direction of induced current in it is opposite to the current direction in the driving coil, or else it will be slowed down. By the finite element analysis, the relationship between the induced current, the velocity of armature, and the waveform of current in the driving coil, is obtained, especially the moment and the position when the armature current reverses its direction or passes zero. The reverse position will be brought forward as the increase of the armature velocity, even the passing zero position of induced armature current will be ahead of the peak point of driving coil current. Thus, it is very important to cut off the current of driving coil at this moment, to avoid slowing down of the armature. Based on the movement and the reverse point of armature current for multiple driving coils system, the trigger strategy of multiple coils can be designed.
Reduced joint counts in controlled clinical trials in rheumatoid arthritis.

OBJECTIVE To determine if quantitative assessment of a reduced number of joints provides information equivalent to that obtained by the traditional 60-joint evaluation in detecting changes in patients participating in clinical trials of rheumatoid arthritis (RA). METHODS The changes in quantitative joint scores of patients from 3 previously reported clinical trials were compiled and compared with changes in quantitative scores derived using a reduced number of joints. Effect sizes were calculated (mean change in joint score/standard deviation of joint score) and compared for the different joint indices. RESULTS The effect sizes of the joint scores derived using a reduced number of joints were similar to those of the original 60-joint score. The reduced joint count scores revealed significant changes for clinical trials involving as few as 15 patients. CONCLUSION Reduced joint count scores may be used to evaluate the results of clinical trials without decreasing the ability to detect change over time. Quantitative assessment of a reduced number of joints may also facilitate assessment of responses to treatment in the routine care of patients with RA.
Loss of heterozygosity analyses of asynchronous lesions of ductal carcinoma in situ and invasive ductal carcinoma of the human breast.

BACKGROUND Ductal carcinoma in situ (DCIS) of the breast is known to possess characteristics of the pre-invasive stage of breast cancer and is the precursor to invasive ductal carcinoma (IDC). However, the natural history of the progression from DCIS to IDC remains unknown at the molecular level. METHODS We investigated the loss of heterozygosities (LOHs) in tumors of seven patients with a history of breast biopsy. The seven specimens were diagnosed as DCIS on histopathological re-examination. These patients were diagnosed with ipsilateral breast cancer a few years after biopsy. We used thirteen selected microsatellite markers that were mapped to and/or very close to the tumor suppressor genes or regions with frequent LOHs in breast cancer. DNA isolated from microdissected formalin-fixed, paraffin-embedded tissues was subjected to a PCR-LOH analysis for these chromosome loci, and the pattern of LOHs was compared between the two asynchronous lesions for the seven cases. RESULTS In all patients except one, the LOHs were concordant at 91% as the informative chromosome loci in cases 1 to 6 were 56, and the concordance in LOH pattern between DCIS and IDC was detected at 50 loci. The LOHs had accumulated in accordance with the tumor progression from DCIS to IDC. The recurrent lesion occurred at or near the site of the primary biopsy and had similar or identical histopathologic features. CONCLUSIONS These recurrences observed were probably residual disease rather than true recurrences. Our results suggest the following: (i) genetic alternations accumulate during cancer progression from DCIS to IDC, (ii) DCIS is a lesion that has a high risk of developing invasive transformation and (iii) after approximately 5 years without treatment, DCIS may develop into IDC.
The Integration of Simulation in Development of Nurses’ competencies in Natural Disaster Situation : A Scoping Review

Nurses preparedness and competencies are of paramount importance in disaster situations. The adverse effect of both natural and man-made disasters is alarming all over the globe, a myopic knowledge cannot deal with the myriad of these disasters rather an in-depth knowledge, skills and competencies are essential to combat them. This research work seeks to examine how simulation studies are being applied in natural disaster situations and how useful simulation studies are in enhancing nurses’ knowledge and their competences in disaster situations. A scoping literature review methodology was used to examine a final number of 13 articles from previous 201 research papers available between year (2012-2017) after duplicated articles were discarded. Data compiled from these articles were classified based on: authors, years, area of focus and collating, summarizing & results reporting. The results extracted from the final data were analyzed by highlighting certain similarities, making comparisons, assertions, and conclusions. Results indicate that, Simulation can be cost effective approach to minimized and prepared for disasters, as well as means of improving nurses’ competencies in disaster situations. The research question; can simulation improve nurses’ competencies in natural disaster situations was answered in affirmative.
The Conditional Nature of Political Risk: How Home Institutions Influence the Location of Foreign Direct Investment

What determines whether countries’ institutions attract or deter investment? Although existing theories predict that multinational enterprises (MNEs) will avoid locations where institutions cannot constrain the opportunistic behavior of public and private actors, we argue that the attractiveness of host country institutions depends on the institutions that investing firms have encountered at home. By shaping firms’ practices and capabilities, home country institutions help determine the institutional environment that firms are best prepared to deal with when investing abroad. Applying this argument specifically to judicial independence, we test our predictions using multiple datasets at different levels of analysis: firm-level data on MNEs’ foreign subsidiaries, data on bilateral foreign direct investment (FDI) positions, and longitudinal data on bilateral FDI flows. We find that states with independent judiciaries are particularly attractive to investment from countries also possessing independent courts. Similarly, FDI from countries with low judicial independence goes disproportionately to host countries lacking independent judiciaries.
Comparison of an immunoprecipitation method for direct measurement of LDL-cholesterol with beta-quantification (ultracentrifugation).

A direct LDL cholesterol assay was evaluated using immunoprecipitation (Sigma Diagnostics, St. Louis, MO) with beta-quantification obtained by ultracentrifugation. Excellent intra- and interassay coefficients of variation were obtained (< 4.5%). There was a good correlation (r = 0.88, P < .0001) between the two methods for low-density lipoprotein cholesterol (LDL-C) in 249 samples with triglyceride levels ranging from 13 mg/dL to 2,236 mg/dL and LDL cholesterol levels ranging from 28 mg/dL to 290 mg/dL. Similar correlations were seen for patients with triglyceride levels < 400 mg/dL (r = 0.89, n = 174) and > or = 400 mg/dL (r = 0.89, n = 75). However, using the Friedewald equation, there was a good correlation only in samples with triglyceride levels < 400 mg/dL. No significant differences were found between LDL-C quantitated by the direct LDL assay and beta quantification for patients with dysbetalipoproteinemia (Type III disorder). However, calculated LDL values using the Friedewald equation were found to be significantly higher when compared to beta-quantification in patients with the Type III disorder. There was a slight but significant decrease in LDL-C determined by direct LDL cholesterol assay for non-fasting versus fasting serum (4.7%) despite a strong correlation between these samples (r = 0.98, P < .0001). In addition, freezing samples for 30 days resulted in a significant decrease in levels (15.1%). Thus, this direct LDL cholesterol assay is recommended in place of beta-quantification in hypertriglyceridemic samples (TG > or = 400 mg/dL) and to monitor LDL cholesterol levels in patients with Type III dyslipidemia, because it is less time consuming, more cost-effective and can be adapted to the clinical laboratory.
An Efficient Implementation of Generalized Delayed Signal Cancellation PLL

The phase, frequency, and amplitude of the fundamental-frequency positive-sequence component of the grid voltage are crucial information in control of most grid-connected power electronic based equipment. Often, a standard phase-locked loop (PLL) with a prefiltering stage is employed for the extraction of this information. Inspired by the concept of delayed signal cancellation (DSC), the generalized DSC (GDSC) operator has recently been introduced as an interesting option for the PLL prefiltering stage. In its typical structure, the GDSC operator extracts the grid fundamental component and feeds it to a conventional synchronous reference frame PLL (SRF-PLL). The frequency estimated by the SRF-PLL is then fed back to the GDSC operator to make it frequency adaptive. This structure, however, suffers from two main drawbacks: 1) the system is highly nonlinear, and therefore, it is difficult to ensure its stability under all circumstances; and 2) adapting the GDSC to grid frequency variations increases the implementation complexity and computational effort, particularly when the interpolation techniques are used for this purpose. To avoid these problems while maintaining high accuracy in the extraction of grid voltage quantities, an efficient and low-cost implementation of the GDSC-PLL is suggested in this paper. The proposed structure, which is called the enhanced GDSC-PLL (EGDSC-PLL), uses a nonadaptive GDSC operator as its prefiltering stage and corrects the phase-shift and amplitude scaling caused by this operator by using two units, called the phase-error compensator and amplitude-error compensator. The effectiveness of the EGDSC-PLL is confirmed through simulation and experimental results.
International Education is Political! Exploring the Politics of International Student Mobilities

Public and academic debates around international students and the internationalization of higher education have been overly concerned with economic issues and insufficiently attentive to the political ramifications of associated changes in educational practices. It takes seriously a call made by Madge et al. (2009), in which they assert that notions of “engaged pedagogy” and “responsibility” need to be explored in relation to international student experiences. Debates have thus far neglected the wider “politics” that underpin the relationship between international students and their “host” university. An awareness of these political relationships has the potential to encourage progressive practices within the institution of the university, including the campus. The article examines the case of transnational education programs in Hong Kong, and considers why a political perspective on international student mobilities is important. The wider goal of this article is to inject some much needed “politics” into discussions of international—and domestic—student experiences.
Intervening Practices for Cyberbullying Prevention

The Internet is a hugely vast, intriguing world, difficult to penetrate in depth, rich with dissimulations, full of useful but also evil things, that is continuously changing. Cyberbullying represents a palpable risk, especially for the online generation who is constantly connected and uses the internet to socialize. The first step for the prevention of cyberbullying is the acquisition of knowledge of what cyberbullying is and how it occurs within a specific context. This is no easy task, since cyberbullying is a complex and creeping new phenomenon, so much so that researcher’s opinions are often divided as to its definition, and there is a lack of agreement on many aspects concerning it. This article presents and comments on some cyberbullying preventing strategies and tips, and is devoted to educators engaged in cyberbullying prevention.
YhgC protects Bacillus anthracis from oxidative stress

Bacillus anthracis can cause lethal inhalational anthrax and can be used as a bioweapon due to its ability to form spores and to survive under various environmental stress conditions. YhgC in bacilli are structural homologues of TRAP, a protein involved in stress response in staphylococci. To test the role of YhgC in B. anthracis, YhgC gene was deleted in B. anthracis strain Sterne and parent and mutant strains tested. Immunolocalization studies indicated that YhgC is clustered both on the cell surface and within the cytoplasm. Phenotypic analyses indicated that YhgC is an important factor for oxidative stress tolerance and for macrophage infection in vitro. Accordingly, transcriptomics studies indicated that yhgC has a profound effect on genes encoding for stress response regulatory proteins where it negatively regulates the expression of genes encoding for Class I and Class III stress response proteins belonging to the regulons hrcA (hrcA, grpE, dnaK, dnaJ, groEL and groES) and ctsR (ctsR, mcsA, mcsB, clpC/mecB, clpP1). Proteomics studies also indicated that YhgC positively regulates the expression of ClpP-2 and camelysin, which are proteins involved in adaptive responses and pathogenesis in various Gram-positive bacteria. Put together, these results suggest that YhgC is important for the survival of B. anthracis under oxidative stress conditions and thus inhibition of YhgC may compromise the ability of the bacteria to survive within the host.

Evaluating Seed Selection for Information Diffusion in Mobile Social Networks

The integration of social networks with mobile communication has led to the rise of a new paradigm, the mobile social network (MSN). Recently, MSN has emerged as a new hot spot of research attracting much interest from both academia and industrial sectors. For instance, MSN opens new horizon for information diffusion-based applications such as viral marketing. Thus, it is a fundamental issue to select an efficient subset of seed-nodes (i.e. initial sources) in a MSN such that targeting them initially will maximize the information diffusion to interested nodes. This paper studies the problem of identifying the best seeds through whom the information can be diffused in the network in order to maximize the content utility (i.e. a quantitative metric that determines how satisfied are the users). A multi- layer model that combines the social relationships and the mobile network in order to design an efficient information diffusion is proposed. Based on this multi-layer model, different seed selection approaches are proposed for information diffusion environment (e.g. mobile advertising) where users have heterogeneous interests for the different information generated in the network. Simulation results show the effectiveness of multi-layer based seed selection approaches comparing to a classical approach.
