Ahasanul Haque, Mohd Shukri Ab Yajid, Ali khatibi & Sabbir Rahman



The growth rate in the Malaysian telecommunication sector was adversely affected over the last decade by Asian economic crisis of the late 1990's. Thereafter, the growth began in befitting manner to a point of excellence. The potential for exponential market growth attracted new players to these businesses soaring dramatic business competition. Nowadays they are trying to attract customers by offering aggressive price promotion. As competition is looming among the companies, it deems a necessity for them to learn the consumers' inherent perceptions about the price, promotion, product and other important commercial factors that may play a pivotal role to choose the tele-service providers. The aim of this study was to find out what were the critical factors that may have played significant role to select the telecommunication service providers. Affirmative result opens a gateway for a comprehensive analysis of such factors which could, in turn, assist the competitors to make uniform decisions on their products and customers. Statistical finding confirms the significant positive relationships among price, service quality, product quality and availability, and promotional offers for consumer perception. Practitioners therefore, can gain a better understanding on these factors in order to satisfy customers and avail market niche.


Critical Factors For Diffusion of Web Technologies In SCM Functions: Malaysian Perspective
Arun Kumar Tarofder



Good supply chain management is essential for a successful company. Supply chain management can reach beyond the boundaries of a single company to share that information between suppliers, manufacturers, distributors, and retailers. This is where the information technologies play an important role. Information technology (IT) facilitates companies to share of large amounts of information along the supply chain, and is often referred to as vital facilitator of supply chain management (SCM) functions. As a new medium of communication, the Internet has conquered the world with break taking speed, and it's the worldwide penetration and high level of standardization contributes to increase globalization. With new web technologies, Internet based systems can deliver functionality and information to user a standard web browser, thereby eliminating requirement for traditional Electronic Data Interchange (EDI) or client based software and reducing information technology implementation and maintenance costs, cycles and burdens. The Internet offers the supply chain immense potential and entirely new ways for streamlining coordination between business partners and customers. Therefore, this study explores the use of use technologies for organizational SCM. Based on an extensive survey of Malaysian organizations, it investigates the diffusion of web technologies into supply chain functions. The findings suggested that top management support and Trialability play crucial role for diffusing web technologies in supply chain. This study provides a greater understanding of managers' perception of web technologies diffusion in their organizations. Those interested in adopting web technologies in their supply chain activates may find these results helpful in guiding their effort.


Implication of possible Foreign Direct Investment (FDI) and Inflation effects on the countries of Association of South East Asia Nations (ASEAN), based on European Monetary Union (EMU) experiences
Abdul Jalil Ghazali, Mohd Shukri Ab Yajid & Ali Khatibi



China, in recent years, has emerged to be the new economic super power, partly due to its low cost production and mass labour force supply. However, ASEAN countries, with total population close to half of China's, pose itself to be another choice in terms of labour intensive industry investment. Therefore, economics integration initiatives, such as AFTA and AEC among the ASEAN countries, will enhance the potential of ASEAN to be the alternative candidate for inter and intra country foreign direct investment (FDI).

Monetary union not only can promote the economic stability in the region, but also serve as catalyze to boost the economic performance of the member countries as a whole. With the removal of uncertainty in currency conversion and high inflation risk, wealthier member countries can invest in less developed member countries to take full advantage of the cheap labour cost, while liberal mobility of labour force within the region will fills up void area that is in need of labour intensive force. This win-win solutions will help speed up the economic development of Cambodia, Lao PDR, Myanmar and Vietnam (CLMV), while retaining capital flow within the region for more developed countries (eg Singapore and Malaysia), and therefore promotes overall prosperity to the region.

This paper examines whether monetary union will encourage Foreign Direct Investment (FDI), and also bring lower inflation rate to ASEAN 9 countries, base on EMU experiences. Using macro-economic data from 9 ASEAN and 12 EMU countries over 25 years (1970 - 2004), the paper analyze and estimates the potential increment in FDI and the reduction in inflation as a results of full fledge monetary integration.

Lumbricus rubellus is a species of earthworm from lumbricidae family which widely used in China, Korea and Japan as alternative medicine in treating disease include thrombosis, bronchitis, typhus fever, tumor and some other diseases. As a folk remedy, Lumbricus rubellus has been known to facilitate blood coagulation, act as antinociceptive, anti pyretic, anti sedative agent and involved in healing process. Experiment were conducted to investigate anti nociceptive properties of earthworm extract derived from species Lumbricus rubellus in identification of paw licking spending time on inflamed mice. The preparation of extraction must be in appropriate procedure and the temperature must be at 38oC in order to keep maintaining their biological composition in earthworm. The earthworm extract with the dose of 300mg/kg, 100mg/kg and 30mg/kg was injected through intraperitoneal (IP) into ICR Albino mice and followed by injection through hind paw by 2.5 % formalin after 30 minutes. Administration of 0.025ml of 2.5 % formalin into the ICR Albino hind paw evokes two spontaneous responses which are flinching or shaking and licking or biting of the injected paw and observation of their behavior. With referring to the high dosage 300mg/kg of Lumbricus rubellus extract were significantly reduced the paw licking time and constantly throughout the period of the experiment at P<0.05. While for the other group, it showed a sharp increase of paw licking time at 10-15 minute duration and gradually decreases during 20-25 minute period. The mean + standard deviation of paw licking time verses period of time in different group which showed is significant difference in paw licking time after the paw edema been induced with formalin between groups at P<0.05 level of significance. As a conclusion, the extract of Lumbricus rubellus has revealed that there is anti nociceptive properties on inflamed mice due to reduction in paw licking spending time with comparison between control group and dose of extract group.

Chuah K.S, Norshafarina S & Halijah H



Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used medications in the world because of their demonstrated efficacy in reducing pain and inflammation. On the contrary NSAIDs are also known to have various adverse drug reactions (ADRs) primarily on cardiac, gastrointestinal and renal system. In addition, under reporting of ADRs has always been a common problem in pharmacovigilance programs. Hence, this study aimed to assess the knowledge, attitude and practices (KAP) on ADRs of NSAIDs and pharmacovigilance among healthcare professionals. A total of 90 healthcare professionals including 30 doctors, 30 nurses and 30 pharmacists are chosen using simple random sampling methodology around Selangor. A newly self-administered KAP questionnaire was designed and given to the healthcare professionals. 51.1% of the respondents were in the age group of 20-29 years old and 66.7% were female. The mean ± SD total score obtained for nurses was 9.06±4.59, 12.16±6.95 for pharmacists and 13.42±5.4 for doctors. The study identified the KAP scores to be low and recommended educational and managerial interventions. It is expected that through these programs the KAP level and awareness on NSAIDs as well as pharmacovigilance will improve substantially, hence lowering the prevalence of NSAIDs-induced ADRs.

Giti Karimkhanlouei, Manoochehr Jafarigohar, Gholam Reza Hessamy & Davoud Karimzadegan Moghadam



Online education is one of the fastest growing modes which afford great flexibility in terms of how, when and where students can learn. This is particularly relevant at higher educational levels since students might often need to manipulate their own learning. A number of studies have compared learning outcomes across online courses and traditional ones (e.g., Alavi, Yoo, and Vogel, 1997; Hiltz, 1993; Hiltz and Johnson, 1990; Leinder and Jarvenpaa, 1993; Piccoli, Ahmad and Ives, 2001).These and other research studies have shown that there are no significant differences between two modes of delivery.The results of this study correspond to some previous studies such as Russel (1999). The statistical analysis revealed that there was no significant difference in achievement of students who were learning English through two modes of instruction.

This study is beneficial to instructors in ESP in developing and using the new mode particularly in different settings.

Redhwan Ahmed Al-Naggar, Karim Al-Jashamy & Saeed Alghalibi



Approximately more than 10 million people chewing fresh leaves of Khat (Catha edulis Forsk) worldwide daily for their stimulating amphetamine-like effects. Khat is highly prevalent in Republic of Yemen and East Africa. The incidence of oral cancer vary across countries due to cultural, living conditions, lifestyles, and the implementation of preventive oral health programs.

While the Southeastern Asia people chewing of betel nuts and some Americans and European chewing tobacco; the East African and Yemenis are chewing Khat which all are risk factor of oral cancer. This review was conducted to review the effects of khat on health. Pub Med, Google and Science direct search engine with key terms 'khat' or 'qat' or 'mirra' or 'qaad/jaad' or Catha edulis were used to obtain English articles relevant to khat chewing which published till 2009. This study concludes that Khat is one of the risk factors of oral cancer. Individual, government precautions should be considered.


Performance Evaluation of Linear Crosstalk Effects in AWG Router in WDM Networks by Comparison between Two Models
Yasin M. Karfaa, M. Ismail, Abbou F. M & S. Shaari



Theoretical analysis is carried out to evaluate the performance of a Wavelength Division Multiplexing (WDM) network transmission system in the presence of crosstalk due to Waveguide Grating Router (AWG) router. It is found that one model results in a better evaluation of impairments due to linear crosstalk induced by the AWG. It manifests that linear crosstalk induces higher penalty when the number of add/drop channels is increased and therefore imposes severe limitation on the maximum number of add/drop channels and the number of users accessing the WDM network.


Development of a High Velocity Impact Testing Rig
Nordin Othman & Fredy Jelema



University Malaysia Sabah only has a low velocity impact testing rig to turn to when they need to do impact testing. There is no high velocity impact testing rig available for researchers to study a dynamic impact testing for materials. With the development of this impact testing rig, it is possible to open new scope of work for material testing. The high velocity impact testing will consist of a gas gun, data acquisition in the form of photogate sensor s and a specimen holder. The gas gun will use a pressurized air as its propellant. The gas gun is consisting of a pressure reservoir and a barrel with a ball valve placed in between them. The ball valve will act as a gating system that release the pressure contained in the pressure reservoir to the barrel to launch the projectiles. The muzzle velocity achieved by this testing rig may vary according to the pressure. A test was done to determine the performance of the impact testing rig. A photogate sensor was use to detect the muzzle velocity. At 8 bar, the impact testing rig muzzle velocity reached 66 m/s with the projectile mass of 30.38g. In order to show the capability of the rig, an example experiment was done. Wood specimens were tested using the high velocity impact testing rig. The kinetic energy of the projectiles relation to the depth of penetration was obtained and plotted. This high velocity impact testing rig has a great potential in the future. The muzzle velocity can be further increase by using a higher capacity compressor. Further development for the rig can include the replacement of the air to light gas such as hydrogen which can provide higher muzzle velocity.
