The development of e-learning products and provision of e-learning opportunities is one of the most rapidly expanding areas of education and training. The growth of e-learning application is accelerating through both offline and online system. These innovative systems are changing the face of learning as we know it. However, what is known about these innovative approaches to training has been limited by the shortage of scientifically evaluation. This study aims to assess students' satisfaction and preference toward a multimedia learning system. This paper describes the evaluation of a package of a Multimedia e-learning system for Computer Aided Design (CAD) practice course. This study develops a questionnaire based on usability evaluation method for a Multimedia e-learning system. The method extends the current practice by focusing not only on cognitive but also affective considerations that may influence e-learning usability. This paper presents findings from a study of the impact of the learning systems. The study also describes designing evaluation sheet, data collection and analysis strategies of a case study on the evaluation of the multimedia learning system implemented for Computer Assisted Design (CAD) Practice Course in Ritsumeikan Asia Pacific University (APU), Japan. © 2016 IEEE.

In this paper, the author demonstrates how commonly used communication scheme and information retrieval which are carried out via Internet using numerous types of smart devices, can turn the Internet into a very dangerous platform because of its built-in nature of making its users' identity easily traceable and discusses some countermeasures that can be used to prevent existing and projected security breaches. It initially provides some introductory information on technology advancement, penetration of the Internet to all aspects of our life and its associated conveniences. It then discusses vulnerability of internet services, presents some typical attack cases that are carried out via smart home appliances, and explains security implementation challenges on such devices from technical, social, and practical aspects. Finally, it proposes an appropriate security model, demonstrates relevant counter measures for numerous attack scenarios, and explains why and how numerous stake holders are needed to get together for its commercial implementation. © 2017 Global IT Research Institute - GiRI.

MatoGrosso has emerged as theBrazilian state with the highest deforestation rate, and with themost dynamic changes in vegetation and land cover. In this article, wefocus on the following two main objectives: (i) to quantitatively assess the extent of vegetation changeoverthepast twodecadesformoreaccurateeco-climatic impactanalysis;and(ii) to clarify the causes to the changes in this state, with special focus to agro-pastoral activities and roads networks. A set of four 5-year digital vegetation model maps was created for the 1981-2001 period, using the first components of the principal components analysis of the National Oceanic and Atmospheric Administration (NOAA)/ Advanced Very High Resolution Radiometer (AVHRR)multispectral data (Channels 1, 2 and 4). Vegetation and land cover changes are characterized by destruction of primary forests in the north and large-scale broad areas with intensive human activity and vast grasslands expanding fromthe south. Large-scale soybean production spreading over the central areas and vast herds of cattle in the north can be pointed to as the main causes of vegetation change in these areas. It is shown that 76.1% of the changes in land cover types occurwithin 30 kmof paved and unpaved roads. This emphasizes the role not onlyof roadbuilding, but also of navigable rivers, in acceleratingdeforestation, especially over the sparsely populated and road-less north. © 2011 Taylor & Francis.

This study investigates the temporal evolution of extreme rainfall seasons over Botswana, and their relationships to the growing season cycle of natural vegetation. Ground-based precipitation data and remotely sensed Advanced Very High Resolution Radiometer (AVHRR)-normalized difference vegetation index (NDVI) data are analysed for the July 1981-June 2006 period. Results confirm that Botswana's annual cycle of precipitation is characterized by substantial intra-seasonal variation, which is resonated in natural vegetation cover. During extreme wet (dry) years, the most extreme surpluses (shortfalls) of monthly rainfall were observed in the middle of the rainfall season (January-February). While rainfall receipts during season onset and cessation may not be the highest, they were found to have strong influence on NDVI coefficient of variation. Extreme wet seasons could be distinguished from moderate wet seasons by examining their monthly peak patterns. Furthermore, the November-December period was identified through the NDVI as the critical period when extreme conditions may begin to emerge. These findings could have important implications for supporting seasonal forecasts and optimizing rainfed agricultural adaptation and natural resources management in southern Africa. © 2016 Royal Meteorological Society.

Cervical cancer resulting from prior infection with human papillomavirus (HPV) is a significant public health threat against young Japanese women. A national immunization plan to vaccinate 13~16 year old female students against HPV infection has been started in Japan since 2010, and may reach almost full coverage by the end of 2012. Older age females who may already be sexually active are not targeted by this plan but should follow safer sex practices as well as periodic screening of the cervix cytology to reduce their riskof developing cervical cancer. HPV vaccination alone does not offer full protection either, because only some HPV types are covered by the vaccines and the long-term efficacy of the vaccines has not been determined yet. Therefore, we did a survey at an international university in Japan to study the knowledge and attitude of female college students towards prevention of cervical cancer, to examine the age when they start sexual activity and other related attributes that may influence the risk of cervical cancer. We discuss the results of our survey and what they imply for the possible impact of an HPV immunization plan on the risk of cervical cancer in Japan, and conclude by an emphasis on the need to increase awareness among Japanese female adolescents and to enhance the cervical screening rates among older females who are already sexually active.

In providing e-Government services, it is necessary to conduct a user-centric evaluation periodically, to improve the usability, accessibility, and effectiveness of e-Government services for citizens. In a qualitative evaluation, gathering user's opinions and recommendations to the e-Government services are commonly used to get a real feedback from the citizens. However, such the user feedback commonly is containing a big text data from diversity of the citizens. It is necessary to do a text mining to assist an analyzing to find out quickly the point of what the citizens recommended. This study proposes an application of Topic Models to do analysis of the big text datasets of the user's feedback. Based on the qualitative analyses approach, the study analyzes user's opinion and recommendation to the e-Government services. The paper also describe designing evaluation sheet, data collection and analysis strategies of a case study in e-Government portals evaluation. © 2013 IEEE.

The paper proposes a model of interregional economic growth model with travel time, housing, residential distribution, and amenity. The economy consists of multiple regions and each region consists of the CBD and the residential area (like in the standard Alonso model). All the markets are perfectly competitive. The paper demonstrates a way to integrate some important models in the literature in transportation research, economic growth theory, urban economics, and regional economics. The simulation results for a 3-region economy provide some interesting insights into national economic development, regional agglomeration, and urban configuration. We demonstrate, for instance, that when the technologically most advanced region improves its transportation conditions, the national output is increased, the advanced region attracts more people from the other two regions, the advanced region's industrial and housing output levels are increased, the other two regions' output levels are reduced, the land and housing rents and residential distribution in the advanced region are reduced near the CBD and increased far away from the CBD, and the land and housing rents and residential distribution in the other two regions are reduced over the entire residential areas. © 2009 Springer-Verlag.

This paper is concerned with multi-regional economic growth with environment, capital accumulation and regional public goods. The economy has a fixed number of regions, and there are a production sector and a public sector in a region. The production sector provides goods in perfectly competitive markets. The public sector, which is financed by the regional government's tax incomes, supplies regional public goods. The public goods affect both firms and households. We show the existence of a unique equilibrium in the dynamic system. We simulate the equilibrium of 3-region economy and examine effects of changes in some parameters on the spatial economy. The comparative statics analysis provides some important insights. For instance, as the technologically least advanced region (TLAR) improves its productivity or amenity, the national output and wealth are reduced, and more people are attracted to the region from the more productive regions. The labor forces in the TLAR's two sectors are increased, and the labor forces in the other two regions are reduced. The change pattern for the capital distribution is similar to the change in the population distribution. The output levels of the two sectors in the TLAR are increased and in the other two regions are reduced. The TLAR's total and per capita expenditures on public goods are increased; the other two regions' total and per capita expenditures are reduced. The per-worker output level, wealth and consumption level per capita, wage rate in the TLAR are increased, and those variables in the other two regions are reduced. The lot size falls and the land rent rises in the TLAR, and the trends are opposite in the other two regions. © 2014 Springer-Verlag Berlin Heidelberg.

In this work, we report the development and experimental validation of a coupled statistical thermo-dynamic model allowing prediction of the structural transitions executed by a novel DNA nanodevice, for quantitative operational design. The efficiency of target structure formation by this nanodevice, implemented with a bistable DNA molecule designed to transform between three distinct structures, is modeled by coupling the isolated equilibrium models for the individual structures. A peculiar behavior is predicted for this nanodevice, which forms the target structure within a limited temperature range by sensing thermal variations. The predicted thermal response is then validated via fluorescence measurements to quantitatively assess whether the nanodevice performs as designed. Agreement between predictions and experiment was substantial, with a 0.95 correlation for overall curve shape over a wide temperature range, from 30°Cto90°C. The obtained accuracy, which is comparable to that of conventional melting behavior prediction for DNA duplexes in isolation, ensures the applicability of the coupled model for illustrating general DNA reaction systems involving competitive duplex formation. Finally, tuning of the nanodevice using the current model towards design of a thermal band pass filter to control chemical circuits, as a novel function of DNA nanodevices is proposed. © The Author(s) 2010.

Some websites are currently listing huge information overloads, with new and emerging ICT capabilities, and with a shortage of information management skills and human expertise. Additionally, various features of information categories and user services are provided in there. E-Government websites in developing countries are a type of the complex websites mentioned above. However, little work is found to evaluate the huge contents of e-Government websites services in this sense. The e-government website design mainly concentrates on website features that would enhance its usability with designer centric approach. A few of them answer why some web design is better than others to facilitate users' information seeking and others services providing. The goal of the research presented in this paper is to explore concepts and models for huge contents websites for developing countries by investigating the characteristics and motivates of the users in browsing the sites to seek information and use others services. We explore the concept by investigating users of e-Government websites of the central government of Indonesia with correspondence analysis. © 2010 IEEE.
