Abstract: The purposes of this research were 1) to investigate
behavior of media exposure and participation in environmental
activities of King Mongkut-s University of Technology Thonburi
(KMUTT) dormitory students, 2) to compare the correlation between
faculties and participation in environmental activities of KMUTT
dormitory students, and 3) to compare the correlation between media
exposure and participation in environmental activities of KMUTT
dormitory students. The tool used for collecting data was
questionnaire. The research findings revealed that dormitory students
were mostly exposed to the environmental media via public relations
boards for general media and KMUTT dormitory media. Dormitory
students were daily exposed to media via websites on the internet and
weekly for other media. Dormitory students participation in the
environmental activities was at high level (x = 3.65) on an
individual basis and was at medium level (x = 2.76) on a collective
basis. Faculties did not correlate with the participation in
environmental activities of dormitory students at the .01 statistical
level and media exposure via various media correlated with
participation in environmental activities of dormitory students at the
.01 statistical level.
Abstract: The purpose of this study was to survey the effect of
organizational communication system on the conflict in physical
education offices of Isfahan province. The research methodology of

exists in physical education offices of Isfahan.
Abstract: Previous studies have indicated that one of the most
critical failure reasons of enterprise systems is the lack of knowledge
sharing and utilization across organizations. As a consequence, many
information systems researchers have paid attention to examining the
effect of absorptive capacity closely associated with knowledge
sharing and transferring on IS usage performance. A lack of
communications and interactions due to a lack of organizational
citizenship behavior might lead to weak absorptive capacity and thus
negatively influence knowledge sharing across organizations. In this
study, a theoretical model which delves into the relationship between
usage performance of enterprise systems and its determinants was
established.
Abstract: The present research was focused to investigate the
role of investment in the course of economic growth with reference to
Pakistan. The study analyzed the role of the public and private
investment and impact of the political and macroeconomic
uncertainty on economic growth of Pakistan by using the vector
autoregressive approach (VAR). In long-run both public and private
investment showed a positive impact on economic growth but the
growth was largely driven by private investment as compared to
public investment. Government consumption expenditure, economic
uncertainty and political instability hampered the economic growth of
Pakistan. In short-run the private investment positively influences the
growth but there was negative and insignificant effect of the public
investment and government consumption expenditure on the growth.
There was a positive relationship found between economic
uncertainty (proxy for inflation) and GDP in short run.
Abstract: In this paper, some new nonlinear generalized
Gronwall-Bellman-Type integral inequalities with mixed time delays
are established. These inequalities can be used as handy tools
to research stability problems of delayed differential and integral
dynamic systems. As applications, based on these new established
inequalities, some p-stable results of a integro-differential equation
are also given. Two numerical examples are presented to illustrate
the validity of the main results.
Abstract: It is not a secret that, IT management has become
more and more and integrated part of almost all organizations. IT
managers posses an enormous amount of knowledge within both
organizational knowledge and general IT knowledge. This article
investigates how IT managers keep themselves updated on IT
knowledge in general and looks into how much time IT managers
spend on weekly basis searching the net for new or problem solving
IT knowledge. The theory used in this paper is used to investigate the
current role of IT managers and what issues they are facing.
Furthermore a research is conducted where 7 IT managers in medium
sized and large Danish companies are interviewed to add further
focus on the role of the IT manager and to focus on how they keep
themselves updated. Beside finding substantial need for more
research, IT managers – generalists or specialists – only have limited
knowledge resources at hand in updating their own knowledge –
leaving much initiative to vendors.
Abstract: The purpose of this study was to explore the
relationship between knowledge sharing and innovation capability,
by examining the influence of individual, organizational and
technological factors on knowledge sharing. The research is based
on a survey of 103 employees from different organizations in the
United Arab Emirates. The study is based on a model and a
questionnaire that was previously tested by Lin [1]. Thus, the study
aims at examining the validity of that model in UAE context. The
results of the research show varying degrees of correlation between
the different variables, with ICT use having the strongest relationship
with the innovation capabilities of organizations. The study also
revealed little evidence of knowledge collecting and knowledge
sharing among UAE employees.
Abstract: The purpose of this research is to develop a security model for voice eavesdropping protection over digital networks. The proposed model provides an encryption scheme and a personal secret key exchange between communicating parties, a so-called voice data transformation system, resulting in a real-privacy conversation. The operation of this system comprises two main steps as follows: The first one is the personal secret key exchange for using the keys in the data encryption process during conversation. The key owner could freely make his/her choice in key selection, so it is recommended that one should exchange a different key for a different conversational party, and record the key for each case into the memory provided in the client device. The next step is to set and record another personal option of encryption, either taking all frames or just partial frames, so-called the figure of 1:M. Using different personal secret keys and different sets of 1:M to different parties without the intervention of the service operator, would result in posing quite a big problem for any eavesdroppers who attempt to discover the key used during the conversation, especially in a short period of time. Thus, it is quite safe and effective to protect the case of voice eavesdropping. The results of the implementation indicate that the system can perform its function accurately as designed. In this regard, the proposed system is suitable for effective use in voice eavesdropping protection over digital networks, without any requirements to change presently existing network systems, mobile phone network and VoIP, for instance.
Abstract: The purpose of the current study is to gain insight into the relative role of professional self-image (PSI) for service providers among leader-member exchange (LMX), career success. Lack of studies demonstrated that PSI of service providers affect on their CS. So, it is necessary to, according to service providers- perspective, explore the relationship among LMX and CS in hospitality industry. The result of the current study can suggest strategic directions for hospitality practitioners in terms of constructing LMX relationship, so as to make service providers realize and build their PSI, and to promote their CS. Implications of these findings for hospitality implementations as well as future research directions are subsequently discussed.
Abstract: Educational games (EG) seem to have lots of potential due to digital games popularity and preferences of our younger generations of learners. However, most studies focus on game design and its effectiveness while little has been known about the factors that can affect users to accept or to reject EG for their learning. User acceptance research try to understand the determinants of information systems (IS) adoption among users by investigating both systems factors and users factors. Upon the lack of knowledge on acceptance factors for educational games, we seek to understand the issue. This study proposed a model of acceptance factors based on Unified Theory of Acceptance and Use of Technology (UTAUT). We use original model (performance expectancy, effort expectancy and social influence) together with two new determinants (learning opportunities and enjoyment). We will also investigate the effect of gender and gaming experience that moderate the proposed factors.
Abstract: Soil erosion is the most serious problem faced at
global and local level. So planning of soil conservation measures has
become prominent agenda in the view of water basin managers. To
plan for the soil conservation measures, the information on soil
erosion is essential. Universal Soil Loss Equation (USLE), Revised
Universal Soil Loss Equation 1 (RUSLE1or RUSLE) and Modified
Universal Soil Loss Equation (MUSLE), RUSLE 1.06, RUSLE1.06c,
RUSLE2 are most widely used conventional erosion estimation
methods. The essential drawbacks of USLE, RUSLE1 equations are
that they are based on average annual values of its parameters and so
their applicability to small temporal scale is questionable. Also these
equations do not estimate runoff generated soil erosion. So
applicability of these equations to estimate runoff generated soil
erosion is questionable. Data used in formation of USLE, RUSLE1
equations was plot data so its applicability at greater spatial scale
needs some scale correction factors to be induced. On the other hand
MUSLE is unsuitable for predicting sediment yield of small and large
events. Although the new revised forms of USLE like RUSLE 1.06,
RUSLE1.06c and RUSLE2 were land use independent and they have
almost cleared all the drawbacks in earlier versions like USLE and
RUSLE1, they are based on the regional data of specific area and
their applicability to other areas having different climate, soil, land
use is questionable. These conventional equations are applicable for
sheet and rill erosion and unable to predict gully erosion and spatial
pattern of rills. So the research was focused on development of nonconventional
(other than conventional) methods of soil erosion
estimation. When these non-conventional methods are combined with
GIS and RS, gives spatial distribution of soil erosion. In the present
paper the review of literature on non- conventional methods of soil
erosion estimation supported by GIS and RS is presented.
Abstract: In the globalization context and competitiveness, the role of a university is further enhanced. University is no longer confined to traditional roles. Universities need to interact with others in order to be relevant and progressive. Symbiosis relationships between the university and industry are very significant because the relationship between those two can foster economic development of a nation. In a world of fast changing technology and competition, it is necessary for the university to collaborate with industry to combine efforts fostering the diffusion of knowledge, increasing research and development, patenting innovation and commercializing products. It has become increasingly accepted that the necessity of close university-industry interactions as a mean of national economic prosperity. Therefore, this paper is aim to examine the level of linkages in university-industry interactions to which promotes the regional economic growth and development. This paper will explore the formation of linkages between the Higher Education Institution (University Technology MARA) and industries located in the Klang Valley region of Malaysia. It will present the university-industry linkages with emphasis on the type of linkages existed, the benefits of having such linkages to promote regional economic development and finally the constraints that might impede the linkages and potentials to enhance the linkages towards economic growth and development.
Abstract: This paper presents a tested research concept that
implements a complex evolutionary algorithm, genetic algorithm
(GA), in a multi-microcontroller environment. Parallel Distributed
Genetic Algorithm (PDGA) is employed in adaptive beam forming
technique to reduce power usage of adaptive antenna at WCDMA
base station. Adaptive antenna has dynamic beam that requires more
advanced beam forming algorithm such as genetic algorithm which
requires heavy computation and memory space. Microcontrollers are
low resource platforms that are normally not associated with GAs,
which are typically resource intensive. The aim of this project was to
design a cooperative multiprocessor system by expanding the role of
small scale PIC microcontrollers to optimize WCDMA base station
transmitter power. Implementation results have shown that PDGA
multi-microcontroller system returned optimal transmitted power
compared to conventional GA.
Abstract: This paper deals with behavior and capacity of
punching shear force for flat slabs produced from steel fiber
reinforced self compacting concrete (SFRSCC) by application
nonlinear finite element method. Nonlinear finite element analysis on
nine slab specimens was achieved by using ANSYS software. A
general description of the finite element method, theoretical modeling
of concrete and reinforcement are presented. The nonlinear finite
element analysis program ANSYS is utilized owing to its capabilities
to predict either the response of reinforced concrete slabs in the post
elastic range or the ultimate strength of a flat slabs produced from
steel fiber reinforced self compacting concrete (SFRSCC). In order to
verify the analytical model used in this research using test results of
the experimental data, the finite element analysis were performed
then a parametric study of the effect ratio of flexural reinforcement,
ratio of the upper reinforcement, and volume fraction of steel fibers
were investigated. A comparison between the experimental results
and those predicted by the existing models are presented. Results and
conclusions may be useful for designers, have been raised, and
represented.
Abstract: This paper presents the mathematical model of electric field and magnetic field in transmission system, which performs in second-order partial differential equation. This research has conducted analyzing the electromagnetic field radiating to atmosphere around the transmission line, when there is the transmission line transposition in case of long distance distribution. The six types of 500 kV transposed HV transmission line with double circuit will be considered. The computer simulation is applied finite element method that is developed by MATLAB program. The problem is considered to two dimensions, which is time harmonic system with the graphical performance of electric field and magnetic field. The impact from simulation of six types long distance distributing transposition will not effect changing of electric field and magnetic field which surround the transmission line.
Abstract: The interaction among information and communication technology (ICT) industries is a recently ubiquitous phenomenon through fixed-mobile integration. To monitor the impact of interaction, previous research has mainly focused on measuring spillover effect among ICT industries using various methods. Among others, inter-industry analysis is one of the useful methods for examining spillover effect between industries. However, more complex ICT industries become, more important the impact within an industry is. Inter-industry analysis is limited in mirroring intra-relationships within an industry. Thus, this study applies the analytic network process (ANP) to measure the spillover effect, capturing all of the intra and inter-relationships. Using ANP-based intra and inter-industry analysis, the spillover effect is effectively measured, mirroring the complex structure of ICT industries. A main ICT industry and its linkages are also explored to show the current structure of ICT industries. The proposed approach is expected to allow policy makers to understand interactions of ICT industries and their impact.
Abstract: Application of synthetic antioxidants such as tertbutylhydroquinon
(TBHQ), in spite of their efficiency, is questioned
because of their possible carcinogenic effect. The purpose of this
study was application of mixtures of natural antioxidants that provide
the best oxidative stability for margarine. Antioxidant treatments
included 10 various mixtures (F1- F10) containing 100-500ppm
tocopherol mixture (Toc), 100-200ppm ascorbyl palmitate (AP), 100-
200ppm rosemary extract (Ros) and 1000ppm lecithin(Lec) along
with a control or F0 (with no antioxidant) and F11 with 120ppm
TBHQ. The effect of antioxidant mixtures on the stability of
margarine samples during oven test (60°C), rancimat test at 110°C
and storage at 4°C was evaluated. Final ranking of natural antioxidant
mixtures was as follows: F2,F10>F5,F9>F8>F1,F3,F4>F6, F7.
Considering the results of this research and ranking criteria,
F2(200ppmAp + 200ppmRos) and F10(200ppmRos + 200ppmToc
+1000ppmLec) were recommended as substitutes for TBHQ to
maintain the quality and increase the shelf-life of margarine.

Abstract:
Innovation is becoming more and more important in
modern society. There are a lot of researches on different kinds of
innovation but marketing innovation is one kind of innovation that
has not been studied frequently before. Marketing innovation is
defined as a new way in which companies can market themselves to
potential or existing customers.
The study shows some key elements for marketing innovation that
are worth paying attention to when implementing marketing
innovation projects. Examples of such key elements are: paying
attention to the neglected market, suitable market segmentatio
reliable market information, public relationship, increased customer
value, combination of market factors, explore different marketing
channels and the use of technology in combination with what? Beside
the key elements for marketing innovation, we also present some
risks that may occur, such as cost, market uncertainty, information
leakage, imitation and overdependence on experience.
By proposing a set of indicators to measure marketing innovation,
the article offers solutions for marketing innovation implementation
so that any organization can achieve optimal results.
Abstract: The integral form of equations of motion of composite
beams subjected to varying time loads are discretized using a
developed finite element model. The model consists of a straight five
node twenty-two degrees of freedom beam element. The stability
analysis of the beams is studied by solving the matrix form
characteristic equations of the system. The principle of virtual work
and the first order shear deformation theory are employed to analyze
the beams with large deformation and small strains. The regions of
dynamic instability of the beam are determined by solving the
obtained Mathieu form of differential equations. The effects of nonconservative
loads, shear stiffness, and damping parameters on
stability and response of the beams are examined. Several numerical
calculations are presented to compare the results with data reported
by other researchers.
