Use Of Internet Among Adolescents In Relation To Gender Biasness And Technostress.
The widespread use of modern information and communication technology (ICT) in work life and private life follows in the wake of rapid advances in technology and popularization of different devices and applications, implying fast changes in exposure profiles in the population over the past few decades. Although the Internet frequently has been characterized as male-dominated, recent evidence indicates that the gender gap in Internet use is rapidly diminishing. If more females are using the Internet, then what specific applications do they prefer and do they differ from those of males? This article presents results from a survey assessing gender differences in specific uses of the Internet. The issue of possible negative effects of exposure to ICT has been raised by various groups. Musculoskeletal symptoms and ergonomics in relation to computer use and different input devices have been examined, but also, mental health effects have been considered .The term techno-stress emerged more than two decades ago, to describe stress reactions in relation to computer use. It was suggested that computer use can lead to psycho physiological stress reactions due to occupational strain, and that these reactions can become conditioned to the computer work environment, leading to symptoms associated with computer use
A study on Human Resource Management Processes and Practices- A Review
Akhilesh Mishra*1, Dr. Shubhashri Bose2
The most important asset for any organization is their Human Resources and they serve the organisation to achieve its goal. Management of human resources plays an extremely vital role as compared to the technology or capital and for its effective management, organization requires effective HRM practices. HRM practices refer to activities of organization directed at managing the puddle of human resources and ensuring that the resources are engaged towards the accomplishment of organizational goal. This paper has been designed to review the existing literature based on HRM Practices. The purpose of this paper is to build up an understanding of HRM Practices and to examine the unique HRM practices implemented by different organisations.
After reviewing the existing literature on HRM practices, the researchers have established that the external as well as internal factors affect the HRM practices which leads to direct or indirect effect on other variables such as employee’s attitude, employee employer relations, financial performance, employee productivity etc. and ultimately contribute to overall corporate performance. On the basis of the literature reviewed, a normative skeleton has been developed that shows how HRM practices leads to overall corporate performance
Medical imaging is a technique that is extensively used to create images of human body for medical and research purposes. Magnetic Resonance Imaging (MRI) is a powerful visualization tool that permits to acquire images of internal anatomy of human body in a secure and non-invasive manner. Automatic brain tumor detection from MRI images has become one of the major areas of medical research. The important task in the diagnosis of brain tumor is to determine the exact location, orientation and area of the abnormal tissues. These papers discuss the performance analysis of image segmentation techniques, viz., K-Means Clustering, Fuzzy C-Means Clustering and Region Growing for detection of brain tumor from sample MRI images of brain. The performance evaluation of the above mentioned techniques is done on the basis of error percentage as compared to ground truth
Design & Simulation of PV Grid system with Dispatchable Supercapacitor
Amit Kumar Rohilla, Bhuvnesh Kumar
This paper presents a reliable, extended range power storage for grid connected PV systems. The power supply consists of solar PV source, a battery and Super capacitor (SC). Main source of power is battery, and is connected with super capacitor. These are connected at the starting and transient phase like overloading. Photovoltaic cell works for the steady condition. The total effect of such arrangement is to improve travel range, reduced size of battery , enhanced excellent response during overloading condition and improved battery life .Better performance which gives optimal use of energy, smooth ride and minimum size of sources of energy. Many stand-alone photovoltaic systems need storage device for providing steady state energy to the load when photovoltaicirradiation is not sufficient. Generally, Batteries are used for such application. Thus, providing a large peak current, like starting of motor, degrades plates of battery, results in devastation of battery. An alternate solution of providing heavy current is to connect battery with super capacitors forming an hybrid energy storage system, for which battery could provide steady state energy also the super capacitor can provide the peak power to connected load. A secondary source, solar panel module is available to charge battery and super capacitor.
Background: Seasonal variations of environmental terrestrial gamma dose rates were measured at the Atomic Energy Centre Dhaka (AECD) campus in Shahbag Thana under Dhaka City from January to December 2015. Aim of the study: This kind of study is required to detect the natural and artificial radionuclides (if any) releasing from nuclear facilities in the country or from neighbouring countries. Materials and Methods: The measurement was performed using a portable High Purity Germanium (HPGe) detector (Model No. GEM25P4-83). The portable HPGe detector was placed at 1 meter above the ground facing downward and data acquisition time was 10,000 sec. Four locations were selected in the AECD campus to obtain the spectrum and those locations were marked out using global positioning system. Results: The average dose rate of the four locations from location-1 to location-4 were 0.428 ± 0.041, 0.344 ± 0.073, 0.355 ± 0.049 and 0.405 ± 0.054 µGy.h-1 respectively. The average dose rate of six seasons such as winter, spring, summer, rainy, autumn and late autumn were 0.377 ± 0.088, 0.421 ± 0.071, 0.385 ± 0.066, 0.358 ± 0.031, 0.281 ± 0.106 and 0.421 ± 0.023 µGy.h-1 respectively. The annual effective dose of the population due to the terrestrial gamma radiation were also calculated and it was varied from 0.208 - 0.627 mSv. The mean annual effective dose was found to be 0.472 ± 0.081 mSv which is comparable to the worldwide average value of 0.48 mSv.y-1. Conclusion: It was observed that winter, spring, summer and late autumn season’s dose rates are higher than those of rainy & autumn seasons.
Detection and Prevention of Black Hole Attack in MANET
Veenita* Shamsher Singh Malik**
The traditional AODV protocol is vulnerable to the well-known black hole attack. In case of multipath AODV, when one path is affected by blackhole attack, then source node can choose another alternative path. In this paper we propose a new type blackhole attack mainly targeting multipath AODV. To the best of our knowledge there is no blackhole attack which specifically targets multipath AODV. Broadly speaking, in the proposed blackhole attack, the attacker looks for nodes through which many alternative paths of multipath AODV passes through. Such nodes are selected and blackhole attack is launched targeting them, thereby damaging more number of paths in a single attempt.Further, the attacker selects only those genuine nodes through more than a threshold number of alternative paths pass through, thereby facilitating the attacker to use less number of nodes. So the attack scheme is power aware. Finally we also propose an IDS to detect the proposed energy aware blackhole attack. NS2 experimental results show the validity of the proposed attack

Ukpabi, Innocent Ogbu, Agwu Sylvester Maduabuchi, Taiwo Joseph Kola
Regulatory credibility is an important framework for effective bank regulation in any financial system. It stimulates not only efficient roadmap for banking industry regulation but for effective supervision. The study contributes to the existing literature by investigating the role of regulatory credibility in effective bank regulation in Nigeria using ex post facto research design to ascertain the direction of causation between assets quality of banks, capital adequacy of banks and liquidity of banks in Nigeria from 2005 to 2010. The results from the Granger casualty test depicts that there is no direction of causation between assets quality of banks, capital adequacy of banks and liquidity of banks in Nigeria within the period under review while the direction of causation between capital adequacy and liquidity is unidirectional within the period under review. Base on the findings, the researcher recommends that regulatory authority should often review their regulatory and supervisory framework to ensure that its policy is always in tandem with international best practices to reduce insider abuse especially in the area of credit risk, market risk and operating risk to mitigate the banking menace of high incidence of nonperforming loans by boosting their assets quality. Banks minimum capital base should be reviewed often at least twice per decade, this will enhance their capital adequacy and reduce the over dependence of the banking sector on the customer’s deposits in Nigeria
Effect of Advertisment on Consumer Buying Behavior
Advertisement plays an important role in modern era as it shapes the attitudes and perceptions of individuals and society which strikingly influences the customer buying behaviour .Any business can get on the road of success when it attracts and retains the consumers with profit and this goal is achieved when company builds a strong consumer perception for its product or service. All the big guns have made significant attempts to ensure quality advertisement and fabrication of strong consumer perception through suitable ways that positively affects the consumer buying behavior because people get knowledge about product through advertisement and other promotional tools and develop perception through company’s activities and his previous experience with that company and past purchase accordingly
Stress is conceived as pressure from the environment, then as strain within the person. The generally accepted definition today is one of interaction between the situation and the individual. It is the psychological and physical state that results when the resources of the individual are not sufficient to cope with the demands and pressures of the situation. Thus, stress is more likely in some situations than others and in some individuals than others. Stress can undermine the achievement of goals, both for individuals and for organisations Dealing with stress-related claims also consumes vast amounts of management time. So, there are clearly strong economic and financial reasons for organisations to manage and reduce stress at work, aside from the obvious humanitarian and ethical considerations. Stress can undermine the achievement of goals, both for individuals and for organisations
Factors Affecting Efficiency of Performance Management System in Public Service Institutions

This paper focuses on the analysis of some factors that affect the efficiency of performance management systems in public service institutions to a various degree. Results are based on a survey that verified hypotheses related to three factors affecting the efficiency of the performance management system in public service institutions – suitability of using standard models of performance management, role of social responsibility in the performance management and interconnection of organizational and individual performance objectives in public service institutions
The significance of the road sector in India cannot be undervalued. It’s one in all the key factors within the economic and cultural progress of the nation.The growth of the infrastructure sector in India has been comparatively slow compared with the commercial and manufacturing sectors. The energy shortage, an inadequate transportation network, and an inadequate water system have caused a bottleneck within the country’s economic growth. The Build-Operate-Transfer (BOT) scheme is currently becoming one in all the prevailing ways that for infrastructure development in India to fulfill the requirements of India’s future economic growth and development. Risk management used as a tool in managing projects so as to reduce risk particularly for projects that involved an enormous amount of cash. In this paper, the factors liable for time overruns for BOT projects are known through a survey. Analysis of the data collected from experts is done by AHP. The relative importance and significance of those factors are investigated. The various types of risk encountered in BOT projects were investigated from the aspect of various key participants. The main purpose of this present work is to investigate critical risks related to Build-Operate-Transfer (BOT) projects in India

Effect of Monetary Policy on Nigerian Stock Market Performance
Assoc. Prof. Clem Nwakoby, AlajekwuUdoka Bernard, PhD. Student,
The study investigated the effect of monetary policies on stock market performance in Nigeria. The study covered a period of 28 years (1986 – 2013). Data were generated from the Central Bank of Nigeria Statistical Bulletin, 2013 edition. The ex post facto research design was adopted. The method of data analyses used are b the Johansen co-integration, OLS and granger causality tests. All Share Index was used as the indicator of stock market performance (ASI) while the explanatory variables includedMonetary Policy Rate (MPR), Treasury bill rate (TBR), Lending interest rate (INT), Liquidity ratio (LR) and deposit rate (DR). The co-integration result indicates that there is long run relationship between monetary policy and stock market performance in Nigeria. The OLS regression result showed that monetary policy significantly explains 53% of changes stock market performances in Nigeria. However, Monetary Policy Rate (MPR) has insignificant positive effect on All Share Index (ASI) while Lending Rate (INT) has significant positive effect on All Share Index (ASI). Furthermore, Treasury Bill Rate (TBR) and Liquidity Ratio (LR) have insignificant negative effect on All Share Index (ASI) in Nigeria; and Deposit Rate (DR) has a significant negative effect on All Share Index (ASI) in Nigeria. The granger causality analyses showed that All Share Index (ASI) has no causal relationship with monetary policy rate (MPR), Treasury bill rate (TBR), and liquidity ratio (LR) in Nigeria. However, All Share Index (ASI) has causal relationship with lending and deposit rates in Nigeria. This indicate that monetary policy has the potential (53%) to influence the stock market, but the causality analyses showed that monetary policy cannot influence stock market performance but rather stock market performance has influenced the direction of monetary policy in Nigeria through lending and deposit rates. Among others, the study recommended that policy makers in Nigeria must be mindful of the unidirectional causality from stock market to the monetary policy variables in formulating monetary policies. This will enable them to sufficiently and timely adjust Nigerian stock market to economic conditions in the country

Role of Remote Sensing and Geographical Information System in Environmental Impact Assessment of Developmental Projects for Environmental Management
Anjali Verma1, Akash Kumar2 and Vivek Kumar Tiwari*2
The fast growth in population, urbanization, change in land use pattern in developing countries have resulted in damage of historical, biological, archeological, aesthetic, visual impacts and pollution in land, water, air and noise. There are needs of a tool which can be capable of complex analysis and produce an alternative plan. Therefore Remote Sensing and Geographical Information System (GIS) are the latest technologies or support system or tool which will produce much more accurate results and perform various geographic analyses even in complex situations. Environmental Impact Assessment (EIA) is a less accurate and time consuming because it has more dependant and independent variables which have to be taken in to account such as Land use, land price, population density, socio-economic level, road accessibility, railway accessibility, air quality, ground water quality, noise level, biological content, historical value, archeological and visual importance etc. Remote Sensing and GIS technique is more comfortable, easy and accurate and complete the EIA of any proposed developmental activity in less time. EIA require reports of potential impacts of any proposed activities. By utilizing GIS modeling tools, potential impacts can be predicted and included in the management and monitoring programs. GIS and remote sensing could be used in environmental monitoring for Land use / Land cover analysis, wetland assessment and ground water modeling, habitat mapping, disaster management etc. Thus, Remote Sensing and GIS techniques play a significant role in Environment Impact Assessment process for the proper management of environment
An empirical study on the importance of technology quality in creating brand preference among the Generation Y (Gen-Y) banking customers in Kerala
The objective of this study was to understand the various determinants that develop satisfaction among Generation Y (Gen-Y) banking customers, and to find out the relative importance of technology in creating brand preference among them. Responses from 400 Gen-Y banking customers in Cochin were collected using a structured questionnaire to examine the role of various determinants to customer satisfaction. The study also envisaged to examine the influence of risk perceptions in moderating the satisfaction feel of Gen-Y in technology enabled service delivery. The data collected were analyzed using structural equation approach using a PLS based tool. The study identified important predictors of service quality in the perceptions of Gen-Y as technology quality and brand image. The human dimension was viewed by Gen-Y as less important. The observation regarding the absence of risk perception in using technology enabled applications truly portrayed the Gen-Y behaviour towards technology usage. Further, it was observed that in perceiving technology quality Gen-Y expects maximum technology enabled applications with minimum service
Towards Peace and Sustainable Development in the North Rift Valley Region of Kenya
North Rift region is found the larger northern Kenya region. Most of the region is dry and is a home to pastoralist communities like the Pokot, Turkana and the Marakwet. Since the colonial era, the region has been marginalized by the successive governments. In fact, for the period that the British colonialists ruled Kenya, the northern frontier was closed to the general public. Pastoralists who live in this region depend mainly on scarce natural resources like pasture, water, natural vegetation and livestock. As such, there is pressure among the communities in terms of sharing thus leading to wars over boundaries, traditional migratory routes, and traditional grazing grounds. Northern Rift also has a very long boundary line with Uganda, Sudan and Ethiopia-countries that have at one time or another been affected by internal strife in the last thirty years leading to proliferation of small arms into the region. The sub counties in the North Rift have been marginalized for a long time hence illiteracy rates are very high and transport and communication is very poor. Since no meaningful investment has been put in place, there are high rates of unemployment. The pastoralists are forced by circumstances to lead sedentary lives hence their livelihoods and their fragile environment have deteriorated greatly. It is against this background that this study aimed at establishing ways of sustaining peace and development in the North Rift region. The study adopted the use of primary and secondary data collection. Primary data collection methods included survey questionnaires, interviews, focus group discussions and participatory observation. The purposive sampling method was employed in determining key informant interview respondents and focus group discussion participants. However, for key informants, there was also a snow-balling sampling approach.In terms of analysis, this exercise incorporated elements of the Theory of Change-based evaluation approach. The evaluation exercise integrated conflict sensitive methodologies in the survey and analysis of findings. Hence, the inquiry included questions aimed at understanding contextual dynamics, as well as sets of questions seeking to measure the extent of realization of project goals. Since peace building programs are not insulated from conflict blindness, conflict sensitive lens specifically the Do No Harm/Local Capacities for Peace framework was used to examine the impact of the intervention on the conflict dynamics. The SPSS software was used to analyze quantitative data. It was established thatconflict mitigating and peace initiatives that have been employed in the North Rift inter alia tracking and arresting of perpetrators of conflicts by the government, creation and activation of community security and vigilante groups, strengthening of elders courts to arbitrate over conflict cases, recovery of stolen animals, introduction of alternative livelihoods, use of traditional early warning systems, inter community peace dialogues, peace committees, and inter community common grazing patterns. Communities have collaborated with NGOs for peace initiatives, relief services and long term development initiatives aimed at sustainable alternative livelihoods. World Vision Kenya has been at the forefront in this regard through a five year peace project, meant to bring peace among the warring communities.

Sonali D. Borkar, Alka R. Sawarkar, Suresh G. Jadhao, Prashant Thakare
Medicinal plants have bioactive compounds which are used for curing of various human diseases as well as animal diseases and also play an important role in healing. Phytochemicals have two categories i.e. primary and secondary constituents. Primary constituents have chlorophyll, proteins, sugar and amino acids. Secondary constituents contain terpenoids and alkaloids. Medicinal Plants have antifungal, antibacterial and anti-inflammatory activities. The present study involves three different medicinal plants Moringa oleifera, Dalbergia sissoo and Saraca indica. The leaves of the selected medicinal plants were washed, air dried and then powdered. The aqueous and alcoholic extract of leaf samples were used for the phytochemical analysis to find out the phytochemical constituents in the plant. The aim of the present study was to carried out the phytochemical analysis of aqueous and alcoholic extract of Moringa oleifera, Dalbergia sissoo and Saraca indica. Moringa oleifera is one of the species of family Moringaceae. Moringa oleifera is commonly known as “Drumstick”. Ashoka is the most ancient tree of India, known as a Saraca asoca (Roxb.), De.wild or Saraca indica belonging to family Caesalpinaceae. Dalbergia sissoo belonging to family Fabaceae and commonly known as Shisham or Sisam. The present study reveals the medicinal values of Moringa oleifera, Dalbergia sissoo, Saraca indica after reviewing their Phytotochemical analysis.
Social Media and Teenage Pregnancy among Students In Secondary Schools In Imenti North Sub-County, Meru County, Kenya
Kiarie Antony Kimemia & Mercy M. Mugambi
There is growing concern with the growth and prevalence of stress among teachers. In most schools, autocratic administration and supervision appear to be the rule rather than the exception. Recent estimates suggest that teachers in Kenya are so demoralized, despised, frustrated and ridiculed that 30 to 40 per cent of them do not enjoy optimum health while 45 per cent experience occupational tedium. It is against this background that this study investigated the relationship between leader behaviour and experienced role stress among primary school teachers in Nyanza province. Given that most studieshave been conducted in industrial settings, this study hopes to fill this gap by deeply exploring incidences of role stress in educational settings within the Kenya context and suggest remedies for mitigating it.The Ex-post facto research design was used to establish the relationship between the independent and dependent variables in the study. Purposive and stratified random sampling techniques were used to select the study sample. The population of the study was 399 primary school teachers drawn from 32 primary schools and 8 District Quality Assurance and Standards Officers (DQASOs) in Nyanza province. Data was collected by means of both structured and unstructured questionnaires and in-depth interviews. Data analysis was performed using the Statistical Package for the Social Sciences (SPSS) Version 16.0. The two tailed t-test and product-moment coefficient of correlation were run to establish the differences and relationships between the independent and dependent variables. The level of significance was set at 0.05. Content analysis of the written free responses was also carried out. It was established that primary school teachers in Nyanza province experience high levels of role stress. It is recommended that individual teachers, educational management personnel, planners and policy makers should have an informed understanding of role stress and its early warning signs hence equip themselves with skills, abilities, behaviours, conflict management and resolution policies and strategies needed to minimize incidences of role stress.
Medical Image Security Based On Diffusion- Substitution Method
Jeannine Nithya M D, Prabhavathi K
In modern applications pertaining to transmission and receiving of multimedia data, the demand for data privacy has never been more significant. Hence, encryption of data becomes very much essential. Many encryption algorithms had been proposed, however, algorithms with high security, good efficiency and high performance are the demands of today’s applications. The work proposed in this paper is a diffusion process involving position based transformation with respect to pixels in two stages of encryption. The first stage involves dividing the image into non-overlapping blocks for which the image size is decided by a key. The second stage involves pixel shuffling with a particular pattern within each block in an image. The encryption algorithm implemented in this paper also validates for colour images of RGB format.
