THE INSTRUMENT USED IN MEASURING EMPLOYEE PRODUCTIVITY BASED ON SOCIAL MEDIA USAGE: A REVIEW

Social media has become a necessity among organization in order to enhance the productivity or job performance among employees. It has been claimed as the effective communication channel among employee to corporate toward collaboration, knowledge sharing, etc. Nevertheless, as the social media become the most priority among individual and organization, it has also become one of the factors that contribute to the disruption of work productivity. Thus, this review paper aimed to conduct comparison analysis in the methodology used and the instrument adopted or developed by researchers in measuring the social media usage and employee productivity. There are 32 studies being selected and the majority of the study has been conducting quantitative approaches through an online survey in identifying the frequency of social media usage. From 32 studies only 5 studies have been applicable in measuring work productivity based on the impact of social media usage. The findings presented in this review paper will provide a deep understanding in designing new instrument in measuring the productivity of employee based on the social media usage rather than any negative factors that contribute to the lowest productivity at workplaces. Keywords: comparison analysis, social media usage, instrument, employee productivity
Resistance to Mitomycin C Requires Direct Interaction between the Fanconi Anemia Proteins FANCA and FANCG in the Nucleus through an Arginine-rich Domain*

Fanconi anemia (FA) is a genetically heterogeneous disorder characterized by bone marrow failure, birth defects, and chromosomal instability. Because FA cells are sensitive to mitomycin C (MMC), FA gene products could be involved in cellular defense mechanisms. The FANCA and FANCG proteins deficient in FA groups A and G interact directly with each other. We have localized the mutual interaction domains of these proteins to amino acids 18–29 of FANCA and to two noncontiguous carboxyl-terminal domains of FANCG encompassing amino acids 400–475 and 585–622. Site-directed mutagenesis of FANCA residues 18–29 revealed a novel arginine-rich interaction domain (RRRAWAELLAG). By alanine mutagenesis, Arg1, Arg2, and Leu8 but not Arg3, Trp5, and Glu7 appeared to be critical for binding to FANCG. Similar immunolocalization for FANCA and FANCG suggested that these proteins interact in vivo. Moreover, targeting of FANCA to the nucleus or the cytoplasm with nuclear localization and nuclear export signals, respectively, showed concordance between the localization patterns of FANCA and FANCG. The complementation function of FANCA was abolished by mutations in its FANCG-binding domain. Conversely, stable expression of FANCA mutants encoding intact FANCG interaction domains induced hypersensitivity to MMC in HeLa cells. These results demonstrate that FANCA-FANCG complexes are required for cellular resistance to MMC. Because the FANCC protein deficient in FA group C works within the cytoplasm, we suggest that FANCC and the FANCA-FANCG complexes suppress MMC cytotoxicity within distinct cellular compartments.

Artificial bee colony based design of the interval type-2 fuzzy PID controller for robot manipulator

The robot manipulators are an extremely nonlinear MIMO and highly coupled system. Further, the performances of the controlled systems are adversely affected by the existence of model uncertainties and disturbances. Therefore, the controller design for robotic systems is a difficult task for controller developer. In this paper, a novel application of the artificial bee colony (ABC) algorithm to optimize the antecedent MFs of interval type-2 fuzzy PID controller (IT2FPID) is proposed for robot manipulators for trajectory tracking problem. In order to show a fair comparison, the tuning of controllers parameter is done with ABC optimization techniques. For investigating the effectiveness, the robustness analysis is also investigated for model uncertainties and disturbance rejections. After simulations studies and comparison with conventional controllers, it is found that IT2FPID controller can not only guarantee best trajectory tracking but also improve the system robustness for model uncertainties and disturbance rejection.
Food and Feeding Habits of Oreochromis niloticus (L.) and Sarotherodon galilaeus (L.) in a Tropical Reservoir

2 Abstract: This paper provides information on the diets of Oreochromis niloticus and Sarotherodon galilaeus in Ero reservoir. Fish species were procured from fishermen every fortnight using gill nets, cast nets, traps, hooks and lines. Specimens were chilled with iced blocks at the point of collection and transported to the laboratory. 494 fish specimens were examined and their stomach contents analyzed. Frequency of occurrence and numerical methods were employed in this study. The result of the analysis showed that O. niloticus and S. galilaeus fed on similar food items. These were mainly macrophytes, Chlamydomonas species and Spirogyra. Other food items include detritus, sand grains and insect parts. Thus both species are omnivorous and occupy the same ecological niche.
The Prevalence, Distribution and Expression of Noncarious Cervical Lesions (NCCL) in Permanent Dentition -

A non-carious cervical lesion ( NCCL) is defined as loss of dental hard tissue in the cervical part of the tooth, not caused by caries, multicausal and insufficiently clarified etiology. Identification of specific etiological factors NCCL is a key in making decisions about treatment. The authors conducted a study to evaluate the prevalence and distribution of noncarious cervical lesions in adults. Material and Methods: The sample of 210 respondents, were divided into three age groups. Clinical inspection has determined the distribution of NCCL within the respondents in relation to their age, teeth groups, vestibular and oral surfaces of the teeth, sides of the jaws and expression of NCCL according to the tooth wear Smith– Knight Index. Results: This research points to a very common finding NCCL within our respondents. Cervical lesions were diagnosed in 78.6% respondents in the first, 91.4% in the second and 97.2% in the third group. It has been shown that the number and expression of cervical lesions increases with age of respondents. Noncarious cervical lesions are usually the most visible on premolars, furthermore the first molars and canines, the second molars and then incisors. The minimum number of lesions were diagnosed in the third molars. Conclusion: Given the high prevalence of NCCL’s, there are reasonable grounds for introducing the tooth wear Index to the wider clinical practice, recording noncarious cervical lesions in dental records, creating specific prevention strategies and effective treatments.
Abnormal compartmentalization of norepinephrine in mouse dentate gyrus in α‐synuclein knockout and A30P transgenic mice

In the dentate gyrus of the mouse hippocampus, presynaptic recruitment of norepinephrine in response to repeated‐burst stimulation can be described in terms of an interaction between storage and readily releasable pools. The dynamics of this interaction depends on neuronal activity (bursting), so that the higher the demand for norepinephrine, the faster it is delivered from the storage pool. We also found that α‐synuclein, a presynaptic protein that plays a crucial role in dopamine compartmentalization in the striatum, is also involved in the compartmentalization of norepinephrine in the dentate gyrus. Experiments in transgenic mice with modified or absent α‐synuclein revealed that the familial Parkinson's disease‐linked α‐synuclein mutation A30P can cause selective changes in the function of noradrenergic terminals. Addition of mutated human α‐synuclein abolished the normal norepinephrine mobilization. There were no compensatory mechanisms available in the norepinephrine presynaptic terminals. In contrast, deletion of mouse α‐synuclein is compensated for by increased vesicle transport from the storage pool. The effects are essentially the same as previously reported for dopaminergic terminals in the striatum, indicating that the important role of α‐synuclein in neurotransmitter mobilization is not limited to dopaminergic terminals.
Cyber risk and the changing role of insurance

ABSTRACTA brief look at how the cyber risk landscape is evolving and what this means from a risk and insurance perspective, particularly as businesses accept they cannot hope to prevent all cyber intrusions regardless of the sophistication of their IT security. While cyber insurance is currently a stand-alone product, we are moving to a future where all classes of risk and insurance will be touched by cyber. Meanwhile, the rapid pace of technological change, increasing connectivity through the internet of Things and the changing MO of cyberattackers introduce new vulnerabilities and increase the potential for systemic and risk aggregation complexities that will need to be measured and monitored by insurers. As cyber underwriters scrutinise the IT security of firms seeking insurance, they also have an important and growing role as a de facto regulator. They are setting the bar for the cyber hygiene standards necessary in order to qualify for insurance, and in so doing, encouraging organisations large and s.
The relationship between insulin secretion, the insulin‐like growth factor axis and growth in children with cystic fibrosis

objective Cystic fibrosis‐related diabetes mellitus (CFRD) is an increasingly common complication of cystic fibrosis. CFRD is preceded by a progressive decline in insulin secretion but there is no accepted definition of the prediabetic state in CFRD. This prediabetic state appears to have adverse effects on clinical status, nutrition and lung function, but there is no direct evidence that the impaired glucose homeostasis is the cause of these deteriorations. This study examined the prevalence of glucose intolerance and impaired insulin secretion in a population of children with CF without CFRD. Severe CF lung disease is often associated with poor weight gain and slower growth but the mechanism for this is still unclear. The relationships between the current state of glucose homeostasis, insulin secretion and the insulin‐like growth factor axis, height velocity, nutrition status and lung function were therefore studied.
A Study on Browser-Based Anti-Phishing Tools

— Phishing is the act of attempting to acquire sensitive information such as usernames, passwords, credit card details etc. by impersonating trustworthy entities in an electronic communication. Phishing attacks can range from and not limited to social web sites, auction sites, banks, online payment processors etc. Such areas are commonly used to lure the unsuspecting public. In order to prevent such attacks, several anti-phishing tools can be employed. Anti-phishing software consists of computer programs that attempt to identify phishing content contained in websites and e-mail. It is often integrated with web browsers and email clients as a toolbar that displays the real domain name of the website the viewer is visiting. This helps to prevent fraudulent websites from masquerading as other legitimate web sites. Anti-phishing functionality may also be included as a built-in capability of some web browsers. There are currently various freely available tools to combat phishing, many of which are web browser extensions that warn users when they are browsing a suspected phishing site. This paper is a comprehensive study of the various browser-based anti-phishing tools

Small RNAs and Transgenerational Epigenetic Variation

Small RNAs are found in eukaryotes and are responsible for regulation of chromatin structure, RNA processing and stability, translation and transcription. 24-nt small interfering RNA (siRNA) are known to mediate gene inactivation via the RNA-directed DNA methylation pathway (RdDM) and are important for natural heritable changes in plant species. DNA cytosine methylation can be maintained between generations and this may be important for accelerated adaption to stress conditions. Research is currently focused toward the epigenetic response to disease, the stability of DNA methylation over generations, the elucidation of newly discovered pathways for de novo DNA methylation, and the application of epigenetic variation to breeding programs. This review aims to give a brief but comprehensive examination on small RNAs and transgenerational epigenetic variation.
Correlation Analysis between the Renewable Energy Source Generation and the Utilization for Smart Grid in Korea

In order to prohibit global warming, various kinds of regulatory policies have been established in the whole world. One example is the establishment of the Renewable Portfolio Standard. It requires the increased portion in energy production from renewable energy sources. The Republic of Korea adopted the act on the promotion of the development, use, and diffusion of new and renewable energy since 2012. However, in spite of the effort on the consideration of the renewable energy sources, it was reported the carbon intensity of electricity in Korea was not that low in 2015. Thus, it is required to examine the recent state of the utilization degree of the renewable energy sources in Korea. This paper analyzed the statistical data provided by Korea Power Exchange (KPX) to examine any problems and solutions for generating electricity from the renewable energy sources. We focused on the generation capacity provided by the power plants participated in the market, the electric power trading amount, and the utilization coefficient for 10 years. By analyzing the data, we provide an alternative to solve some imbalance among the factors contributing to renewable energy use.
A comparative study on face spoofing attacks

In the last 57 years, face biometrie researchers have achieved many successes. Face recognition systems have been extensively used in government as well as commercial applications such as mobile, banking and surveillance systems etc. In the last 10 years, the whole biometric community such as researchers, developers, and retailers have worked on challenging tasks to develop a more accurate protection method against spoofing threats. The face spoofing attacks affect high-security field in the companies, government sectors, rising small and medium sized endeavors. Although several face antispoofing or liveness detection methods have been proposed, the issue is still unresolved due to difficulty in finding the features and methods for spoof attacks. Recently it has been shown that the traditional face biometric techniques are more vulnerable to spoofing attacks, so entire research community required to concentrate more to resolve solutions against spoofing attacks. The goal of this paper is to provide a detailed study of antispoofing methodologies and evaluation of databases. The study concluded that there is a need to provide more generalized algorithms for detection of unpredictable spoofing attacks in order to make the system more secure, computationally efficient and reliable.
Robotic Adversarial Coverage : From Theory to Practice

This work implements and simulates the problem known as adversarial coverage. In this problem, a robot is required to visit every point in a target area, which contains hazards or threats that might stop the robot. The objective of the robot is to cover the target area as quickly as possible, while maximizing the probability of completing the coverage before it is stopped. Previous studies of this problem have assumed a simple, unrealistic model of the robot and the environment. In this paper we show how adversarial coverage can be executed on a realistic robotic platform, and we evaluate its performance on large-scaled realistic environments. We also show how the coverage algorithm can be modified in order to significantly reduce the number of turns the robot makes along the coverage path, hence allowing the coverage to complete much faster. Our implementation is based on the standard robotic platforms ROS and Stage.
Voyager 1 Explores the Termination Shock Region and the Heliosheath Beyond

Voyager 1 crossed the termination shock of the supersonic flow of the solar wind on 16 December 2004 at a distance of 94.01 astronomical units from the Sun, becoming the first spacecraft to begin exploring the heliosheath, the outermost layer of the heliosphere. The shock is a steady source of low-energy protons with an energy spectrum ∼E–1.41 ± 0.15 from 0.5 to ∼3.5 megaelectron volts, consistent with a weak termination shock having a solar wind velocity jump ratio \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(r=2.6_{-0.2}^{+0.4}\) \end{document}. However, in contradiction to many predictions, the intensity of anomalous cosmic ray (ACR) helium did not peak at the shock, indicating that the ACR source is not in the shock region local to Voyager 1. The intensities of ∼10–megaelectron volt electrons, ACRs, and galactic cosmic rays have steadily increased since late 2004 as the effects of solar modulation have decreased.
Hip fracture risk and subsequent mortality among Alzheimer ’ s disease patients in the United Kingdom , 1988 – 2007

Background: the diagnosis and management of obstructive airway diseases (OADs) such as asthma and chronic obstructive pulmonary disease (COPD) can be challenging in older people. Objective: to assess the clinical, functional, biological and behavioural characteristics relevant to the management of older people with OAD. Methods: a cross-sectional study was conducted in a tertiary teaching hospital. Older people (>55 years) (n= 100) with an OAD underwent a multidimensional assessment (MDA) involving questionnaires, clinical assessments, physiological measurements and biomarkers. Results: the assessment identified a mean (SD) of 11.3 (2.5) clinical management issues and 3.1 (1.8) comorbid conditions per participant. Common problems were: airways hyper-responsiveness (80%); airway inflammation (74%); activity limitation (74%) and systemic inflammation (60.5%). The number and type of issues were similar irrespective of a diagnosis of asthma or COPD (P= 0.2). The degree of health status impairment correlated significantly with the number of clinical management issues detected (r= 0.59; P < 0.0001). Conclusions: older people with OAD experience multiple clinical issues that adversely impact their health status. The number and type are similar irrespective of diagnosis. This MDA identifies significant clinical issues that may not be addressed in a diagnosis centred approach suggesting that a multidisciplinary approach is necessary when assessing and managing older people with OAD.
Dual-band RF receiver for GPS and compass systems in 55-nm CMOS

A fully integrated dual-band RF receiver with a low-IF architecture is designed and implemented for GPS-L1 and Compass-B1 in a 55-nm CMOS process. The receiver incorporates two independent IF channels with 2 or 4 MHz bandwidth to receive the dual-band signals around 1.57 GHz respectively. By implementing a flexible frequency plan, the RF front-end and frequency synthesizer are shared for the dual-band operation to save power consumption and chip area, as well as avoid any LO crosstalk. A digital automatic gain control (AGC) loop is utilized to improve the receiver's robustness by optimizing the conversion gain of the analog-to-digital converter (ADC). While drawing about 20 mA per channel from a 1.2 V supply, this RF receiver achieves a minimum noise figure (NF) of about 1.8 dB, an image rejection (IMR) of more than 35 dB, a maximum voltage gain of about 110 dB, a gain dynamic range of more than 68 dB, and an input-referred 1 dB compression point (P1dB) of about -36.5 dBm with an active die area of 1.5 ×1.4 mm2 for the whole chip.
How does employee engagement improve the bottom line? Analysis of underlying organizational mechanisms

Decades of research effort have been dedicated to study the relationship between the management of human resources (HR) and firm performance. Research has demonstrated that HR practices, when implemented together as a system (i.e. high-performance work system) have significant and positive impact on organizational outcomes. Yet, the understanding of how such a system achieves the outcomes remains fragmented. The goal of this paper is to review existing empirical and conceptual literature and highlight the various perspectives regarding the mediating relationships between these systems and outcomes. These perspectives are then integrated into a two-layer qualitative model that illustrates the functioning of a highperformance work system at the individual and the collective level.
