Mobile devices and mobile services now have a close relationship in the new product development process. We attempted to draw an integrated strategy through research related to product and service. In this study, we selected tablet PC as a mobile device and mobile Internet as a mobile service. We explored relevant variables when to plan tablet devices related to use of mobile service and found other variables as a mediator. The mediator is considered as a proxy variable that indicates the direction of the company’s product strategy. We employed intention to use as a dependent variable from IDT, TAM and concentrates on two specific aspects as a dependent variable for information and entertainment. We considered relative advantage related to contents/display and compatibility as independent variables. Image and company’s reputation was considered as a mediator to relative advantage and compatibility on intention to use tablet devices. We constructed a structural model, verified the model fit, and tested the hypothesis. Such structure was proven to be a statistically significant fit. From this, it can be concluded that in the managerial perspective, when planning and developing tablet devices, the accessibility and usability of the tablet contents and the innovative image of the function and specification of the tablet’s display should be considered. The relative advantage of tablet device contents largely contributes to the company’s reputation. Company’s reputation is a more appropriate variable for information devices than entertainment ones. Finally, the intention to use a tablet for information on the Internet had a statistically significant effect on the intention to use tablet for entertainment. This can be seen as a utilitarian usage influencing a hedonic variable. Studies on product innovation must have a close relationship with service innovation. Product innovation research must include related service variables and service innovation research must include variables related to the product. Examining On Customer Retention Of Visits On Service Qualities And Word Of Mouth Intention In Upscales Malay Restaurant Through Utilitarian And Hedonic Value Judgements Muzzamir Bin Musa Department of Culinary Arts and Gastronomy, Faculty of Hotel & Tourism Management, Universiti Teknologi MARA (UiTM), Malaysia Abstract-Service qualities in food industries, a technological interface where the customer takes on a partial employee role during a service experience, has become a topic of growing interest to many food services businesses. The research on service quality in the Upscale Malay Restaurant is rather sparse, with the majority of studies, performing qualitative analysis on what customers like and dislike about the restaurant. This study is to review empirically how both the utilitarian and hedonic aspects of a service quality in the Upscale Malay Restaurant. The experiences have also influenced a consumer’s future behavioral 3 003-icbth intention to visit. In an addition, predictors of utilitarian and hedonic value judgment are proposed and tested. This study attempted to investigate on the consumers’ intention of the visit by effect of word of mouth intention. Though a consumer’s perceived utilitarian value had a stronger effect, the hedonic judgment that takes place in a service experience was found to have a significant impact on consumer attitudes. This dissertation was set to examine the consumers behavioral toward Upscale Malay Restaurant. It also hypothesized and predict consumer utilitarian and hedonic attitudes toward service quality and customer retention of visits. If consumers know about service quality that the restaurant was given, the consumer will use both types of these value judgments in forming an attitude about the service which ultimately influences their future behavioral intentions to visit the restaurant. Keys word: Upscale Malay Restaurant, Customer Retention Of Visit, Service Qualities, Word of Mouth, Utilitarian and Hedonic attitude Identifying Service Quality As Antecedents To Customer Loyalty, Customer Satisfaction And Customer Commitment In Islamic Banking Industry Fettie Zanzilla Binti Zainol Department of Marketing , Faculty of Business Management University Technology Mara (Uitm) Malaysia 4 005-icbth This study attempted to investigate on the service quality, providing by Islamic banking industry and how it is affected by the customer loyalty, customer satisfaction, and customer commitment. As we altogether know, one of the primary elements that will tempt the customers committed to the bank depends on the character of the help provided by the manufacture itself.Quality consists of preparing service or stuff to use that it itself needs quality planning, adaption, being accessible and proper place for offering services (Louothetis, 1992). The issue highlighted in this conceptual paper regarding the customer loyalty, customer satisfaction and commitment to service quality that provided by the industry. The work of Islamic Banking derives from Islamic Principal and Syariah that is differences with the conventional bank. Therefore, it's important for banks to determine customer's expectation towards service quality in order to commit the relationship in the Islamic banking industry and develop services that exceed their expectations. On the other hands, this study examines a relationship of service quality to customer satisfaction, customer loyalty and also customer's commitment towards the Islamic banking industry. Keywords: Service quality, Customer satisfaction, Customer loyalty and Customer commitment A Study of patientS’ satisfaction on service quality in the sarawak rural health care industry Saloma Emang , Gladys Sebi Entigar , Noor Haty Nor Azam , Pauline Achan , Jati Kesuma , Muhammad Jastu Faculty of Business Management, University Technology MARA, Malaysia Corresponding author: Saloma Emang, Faculty of Business Management, University Technology MARA, Campus Kota Samarahan, Malaysia Abstract-The level of customers’ satisfaction is an effective pointer for a service quality measurement as it is based on the respondents’ judgment toward the services rendered to and experienced by them. The main purposes of this study were to identify the relationship between service quality and customer’s satisfaction and to determine which dimension of SERVQUAL has the highest impact on customers’ satisfaction, of which the focus was the out-patients visiting the Sri Aman Polyclinic, Sarawak. Descriptive statistics and correlational approach were carried out by using SERVQUAL and Patient Satisfaction questionnaire. Reliability and validity of the SERVQUAL and Patient Satisfaction instrument were established. The respondents in this study consisted of 100 out-patients who visited the Sri Aman Polyclinic, Sarawak, Malaysia. The findings indicated that Empathy had a significant relationship with patients’ satisfaction while Assurance was shown to have the highest impact on the patient’s satisfaction. In a nutshell, it was pointed out that the service quality at the Sri Aman Polyclinic was significantly related to the 5 006-icbth patients’ satisfaction. Thus, this study should be extended to the other rural areas in Malaysia, especially in the healthcare industry Border Tourism: Factors Affecting Self-Efficacy of Entrepreneurs in Northern Malaysia and Southern Thailand Mohd Najib Mansor , Abdul Rahim Othman , Kamarul Bahrain Abdul-Manaf , Mohd Sobri Don @ A.

Therefore, it is important to understand factors that drive local entrepreneurs to become successful in their business. Self-efficacy is a concept used in the literature to measure one’s belief in his ability to successfully venture into a business. Objective: This paper examines the relationship between entrepreneur demographic factors, environmental forces and entrepreneurial self-efficacy of small business operators at the border towns of Malaysia and Thailand. The research is a cross-sectional study and a survey method is used. Results: Our result reveals that nationality has a significant relationship with entrepreneurial self-efficacy. With regard to the environmental forces, there is also a positive relationship between intensity of competition and entrepreneurial self-efficacy. Conclusion: Our result on environmental forces is not consistent with those studies conducted in western countries. It seems that the small business operators at border town of Malaysia and Thailand have the same belief which is different from those in western countries.

Graduate School of Business, Universiti Kebangsaan Malaysia (UKM), Bangi, 43000, Selangor, West Malaysia. 7 008-icbth Abstract-Background: Malaysia is taking aggressive steps for recruiting international students from various countries due to the potential high economic contributions in return and being ideal educational hub in the region. Various studies conducted in exploring international students motivational factors to study abroad, but limited on ‘perceived risk’ that may influence their decision making process greatly. Thus, this research main aim is to propose the influence of perceived risk in moderating students’ decision making process when selecting higher education (HE). This study contributes in the current HE decision making literature and understands better on the complexity of perceived risk in HE by explaining five types of risk component briefly. Cultural Intelligence and Export Success : Firm-level Cultural Capability for Penetrating Overseas Markets Marlin Abdul Malek, Abd Rahim Jaguli , Sabariah Yaakub Othman Yeop Abdullah Graduate School of Business, Universiti Utara Malaysia, Sintok, 06010 Kedah, Malaysia School of International Studies, Universiti Utara Malaysia, Sintok, 06010 Kedah, Malaysia School of International Studies, Universiti Utara Malaysia, Sintok, 06010 Kedah, Malaysia Abstract-This research investigates the relationship between firm-level Cultural Intelligence and Export Success in supporting firm’s entry strategy. This study endeavours to investigate whether firm-level cultural intelligence will positively influence the firm’s export success in the context of Malaysian exporters entering any foreign market. Firm-level CQ here is referring to the firm’s managerial, competitive and structural capabilities and export success is referring to financial export performance, strategic export performance and satisfaction 8 009-icbth with export venture. The findings obtained from this study were able to demonstrate the relationship between firm-level CQ and various indicators of export success that are directly related to export performance, market entry strategy and internationalization endeavors. With globalization, having the knowledge and embodying the CQ concept will be an added repertoire of skills and strategies that managers and MNCs should possess especially with the opening up of non-traditional markets like China and other emerging economies. The Effect of MNCs Innovation Activities in Stimulating Malaysia’s Outward Foreign Direct Investment (OFDI) – A Conceptual Framework Abd Rahim Jaguli , Marlin Abdul Malek , Nurhaizal Azam Arif School of International Studies, Universiti Utara Malaysia, Sintok, 06010 Kedah, Malaysia Othman Yeop Abdullah Graduate School of Business, Universiti Utara Malaysia, Sintok, 06010 Kedah, Malaysia School of International Studies, Universiti Utara Malaysia, Sintok, 06010 Kedah, Malaysia 9 010-icbth Abstract-The objective of this paper was to propose a framework of study on the effect of MNCs innovation activities in stimulating Malaysia’s Outward Foreign Direct Investment (OFDI). Studies on channels through which technology and knowledge were transferred remained unexplored in the existing OFDI knowledge transfer literature. The study will investigate the drivers of Malaysia’s OFDI particularly the effect from international external sources. It will examine whether multinational corporations (MNCs) innovation activities can act as catalysts to stimulate OFDI activities in Malaysia. This study will adopt an aggregative approach using macro-level data. Time series data analysis will be conducted to provide empirical evidence of the effect of foreign innovation activities on Malaysia’s OFDI. Data for analysis purposes will be obtained from the World Bank’s World Development Indicator (2014). In parallel with the data sources, statistical tests will be conducted on the main determinants of OFDI and the effect of foreign innovation and international trade activities on OFDI performance of Malaysia. The Travel Motivations of Tourists: A Case of Mauritius Perunjodi Naidoo, Prabha Ramseook-Munhurrun, Abhishek Seetaram University of Technology Mauritius, School of Sustainable Development and Tourism, Mauritius University of Technology Mauritius, School of Sustainable Development and Tourism, Mauritius 10 001-icc Abstract-Background: This research assesses the motivational pull factors that influence a tourist`s selection of a holiday destination. A total of 254 questionnaires were collected from tourists who have visited or will visit Mauritius as a holiday destination at different locations in London. The results show that increase in disposable income is the most important push motivation followed by prestige, opportunities to expand knowledge, socialization and social interaction. The major pull motivation was seen to be the safety and security, distance, shopping facilities, sports & activities, and novelty. The study adds to understanding the reasons why holiday makers choose long-haul destinations like Mauritius. The findings of this study can help destination marketers better market the destination and promote the attributes required by tourists. Computational Investigation of the Monomer Insulin-β-CD Complex for the New Insulin Formulation Erma Fatiha Muhammad and ,Rohana Adnan School of Chemical Sciences, Universiti Sains Malaysia, 11800 USM, Penang, Malaysia. Abstract-The complexation of insulin with beta cyclodextrin (β-CD) would be to improve absorptive and stability of the formulation insulin. This paper reports our investigation on the interaction between insulin with several β-CDs at the molecular level using the combined docking and molecular dynamics simulation methods. The present study was aimed at finding the best possible ratio of β-CD to insulin, its most stable conformation as well as identifying the type of forces responsible for the stabilization of the complex. A series of 90 ns molecular dynamics simulations were conducted using NPT ensemble to further verify the results obtained by multiple molecular docking approach. Our results show 11 003-icc that the most stable conformation obtained was the one insulin to three β-CD ratios, which is stabilized mostly by hydrophobic interactions as well as hydrogen bonds formations. MD analysis of the insulin-β- CD complex system reported a good interaction between insulin and β-CD with the root mean square deviation values of the insulin in complex system stabilized at 80 ns was 0.65 ± 0.05 nm. RMSF profiles of the complex system also shows the flexibility of Asn21, Phe22, Val23 and Asn24 residues which are involved in the hydrogen bonding and hydrophobic interactions in docking calculations. The theoretical results indicated the presence of significant interactions between insulin and β-CD which could help in the new insulin formulation. Scrutinizing The Characteristics Of Deproteinised Natural Rubber Latex Containing Sodium Dodecyl Sufate NURULHUDA ABDULLAH, SITI NOR QAMARINA MANAF, MOK KOK LANG AND AMIR-HASHIM MOHD YATIM Technology and Engineering Division, Malaysian Rubber Board, 47000, Sg. Buloh, Selangor D.E Malaysia Center of Excellence, Malaysian Rubber Board, 47000, Sg. Buloh, Selangor D.E, Malaysia 12 005-icc Abstract-An extension study on the role of sodium dodecyl sulphate (SDS) in deproteinised natural rubber latex (DPNRL) was performed. It was observed that SDS effectively facilitated the removal of proteins during the deproteinisation process of which about 20 – 80% of proteins was removed. Almost a complete reduction (97%) in extractable proteins (EP) was seen in cast films prepared from these SDS-DPNR mixtures. The presence of SDS had resulted in smaller particle size diameter however there was no distinct difference in their effective particle size diameter as the SDS concentration increases. Slight agglomeration was seen at high SDS concentration. The zeta potential was enhanced as the SDS concentration increased indicating higher colloidal stability. Depending on the SDS concentration the presence of SDS in DPNR latex also rendered stabilization effect as observed during the mechanical stability test. SDS resulted in low flow behaviour where the latex became viscous with increasing SDS concentration. Deproteinisation caused marked reduction in crosslinking density consequently leading to lower mechanical strength. Effect of Locality on Carotenoids Stability in Malaysian Orange Sweet Potato (Ipomoea batatas) Tuber Flesh Suhair Kammona, Rashidi Othman, Irwandi Jaswir, Parveen Jamal Department of Biotechnology Engineering, Kulliyyah of Engineering, International Islamic University Malaysia (IIUM), Jalan Gombak, 53100 Kuala Lumpur, Malaysia, International Institute for Halal Research and Trainin g (INHART), Herbarium Unit, Department of Landscape Architecture, KAED, IIUM, Jalan Gombak, 53100 Kuala Lumpur, Malaysia 13 006-icc ABSTRACT: Background: Carotenoids are bioactive antioxidant pigments with pharmaceutical potential. Carotenoids such as α-carotene and β-carotene react as provitamin A in human body, while lutein and zeaxanthin are two major components of the macular pigment of the retina. Due to its high carotenoids and pro-vitamin A content, sweet potato (Ipomoea batatas) is believed to have many nutritional and medicinal benefits. The carotenoid content in sweet potato or as locally known Keledek in Malaysia were determined using spectrophotometry and high performance liquid chromatography HPLC analysis. Objective: This study aimed to assess the carotenoids content stability in five different localities in Malaysia (Kelantan, Pahang, Terengganu, Selangor and Perak) of orange sweet potato tuber. All analyses were carried out in triplicate. Results: Results of this study revealed that the orange sweet potato (OSP) from Kelantan showed the highest total carotenoids content. For individual carotenoids, β-carotene ranged from 1123.85±0.04 μg/g to 399.4±3.62 μg/g DW. Zeaxanthin was detected only in Kelantan OSP 13.01±0.00 μg/g DW. Carotenoids profiles for orange fresh tubers from five Malaysian localities revealed marked differences in individual carotenoids composition. Conclusion: Generally, location or geographic site of crop can be considered as an important factor that affects carotenoids content in sweet potato flesh tuber. Identification of Total Carotenoids and β-Carotene Content In Different Flesh Tuber Colours of Local Sweet Potato (Ipomoea batatas) for Pharmaceutical Industry Suhair Kammona, Rashidi Othman, Irwandi Jaswir, Parveen Jamal Department of Biotechnology Engineering, Kulliyyah of Engineering, International Islamic University Malaysia (IIUM), Jalan Gombak, 53100 Kuala Lumpur, Malaysia, International Institute for Halal Research and Training (INHART), Herbarium Unit, Department of Landscape Architecture, KAED, IIUM, 14 007-icc Abstract: Five varieties of sweet potato tuber in Malaysia, have been studied for their total carotenoid contents and βeta- carotene content through spectrophotometry and high performance liquid chromatography HPLC analysis. This study was conducted to compare carotenoids content in local orange, yellow, purple and white sweet potato tuber pulp. UVspectrophotometry analysis revealed that the orange sweet potato tuber flesh had the highest both β-carotene content and total carotenoid concentrations comparing to other sweet potato tuber flesh colors. Malaysian orange sweet potato showed the highest values of total carotenoid content and β-carotene concentration while white sweet potato showed the lowest levels of total carotenoid content and beta-carotene. In general, results of this study revealed that carotenoid content can differ with type of sweet potatoes flesh tuber. This study aimed to evaluate the high nutritional value of local sweet potatoes in Malaysia and their potential use in Pharmaceutical Industry. Effect of torrefaction atmosphere on the mass yield, elementary composition and calorific value of empty fruit bunches (EFB) Mohammad Hisham Sulaiman , Yoshimitsu Uemura , Mohammad Tazli Azizan Universiti Teknologi PETRONAS, Centre for Biofuel and Biochemical Research, 32610, Bandar Seri Iskandar, Perak, Malaysia. Universiti Teknologi PETRONAS, Department of Chemical Engineering, 32610, Bandar Seri Iskandar, Perak, Malaysia. 15 008-icc Abstract-Malaysia has an abundance of oil palm biomass residues which are underutilized. In specific, empty fruit bunches (EFB) are the representative one. EFB has some drawbacks, such as biodegradability and low calorific value, as a solid fuel. A medium temperature treatment called torrefaction can improve these disadvantages. If the flue gas in palm oil mills can be utilized as the gas and thermal energy sources of torrefaction, the financial feasibility would be well improved. This study investigated the torrefaction of empty fruit bunches under inert and non-inert atmosphere (oxygen and carbon dioxide). The torrefaction process was conducted at 300˚C for 30 min. The effect of the presence of oxygen, dioxide and mixture of oxygen and carbon dioxide was studied and compared with torrefaction under inert atmosphere. The solid yield of torrefied EFB with the presence of carbon dioxide or oxygen obviously decreased in comparison with inert. Torrefaction under 21% carbon dioxide resulted in better characteristics of solid products in terms of carbon content and calorific value, thus enhancing EFB as a solid fuel. Scanning electron microscopy (SEM) was used to observe the morphology of the untorrefied and torrefied EFB. Transesterification of Palm Oil with Methanol in a Millichannel Reactor: Effects of Methanol to Oil Molar Ratio and Reaction Temperature Nurul Asyikin Mohd Azam, Yoshimitsu Uemura, Katsuki Kusakabe, and Mohamad Azmi Bustam Centre for Biofuel and Biochemical Research (CBBR), Universiti Teknologi Petronas, 2610 Bandar Seri Iskandar, Perak, Malaysia Department of Nanoscience, Sojo University, Kumamoto, 860-0082, Japan Department of Chemical Engineering, Universiti Teknologi Petronas, 32610 Bandar Seri Iskandar, Perak, Malaysia Biodiesel, a biomass-derived fuel, is becoming increasingly important due to the increase in the price of petroleum and the environmental concerns about the pollution that release to the environment by vehicles and factories. Recently, millichannel reactor has become one of the methods to produce biodiesel because it can overcome several issues in the traditional approached of biodiesel production. In this paper, transesterification of palm oil using 16 001-iciae millichannel reactor was conducted to study the effect of methanol to oil molar ratio (6:1 to 23:1), reaction temperature (40-65 °C), on the FAME yield for two different tube internal diameters; 1.6 and 1.0 mm on the FAME yield. Results showed that the highest FAME yield was at 21:1 methanol to oil molar ratio and the temperature was 60 °C with internal diameter 1.0 mm.

Thailand Abstract- The main objective of this study is to analyze economical possibility of 3 MW electricity generation power plants fuelled by biogas produced from 3 types such as the wastewater, decanter cake and elephant grass from palm oil industry by discount rate on investment in case of non subsidy and 20% subsidy. The analysis includes capital investment, operation costs, profitability and revenues of the very small power plant, where, this scenario analysis is carried out based on the data from the survey sample palm oil mill to identify possibility project that optimize electricity production. This economic performance biogas plant based on NPV, IRR and PBP concepts. The findings of the analysis indicate that HCD system of the wastewater is financially feasible. The results obtained indicate a positive NPV and acceptable IRR and a PBP of less than 5 years and it’s generally no cost. The CSTR co-digestion of decanter cake can yield an IRR of approximately 11.3% but PBP more than 14 years. Elephant grass biogas system is impossible. The analysis suggests that industrial that further support mechanisms from the government in terms of investment subsidies, soft loan, crop pricing scheme and special subsidies of feed in tariff (FIT) of adder are financially crucial to project survival. 17 002-iciae The transmission dynamics of Denque fever with optimal control theory BunditUnyong1,* 1,* Department of Mathematics, Faculty of Science and Technology, Phuket Rajabhat Univers ity, Phuket, 83000. Thailand Abstract- Background: In this work the dynamics transmission of denque fever was proposed. The standard method is used to analyze the behaviors of the proposed model. After that the model is modified by adding optimal control functions that includes two time – dependent control functions with one minimizing the contract between the susceptible human and the infected vector and the other, minimizing the population of the infected human. Results: The results shown that there were two equilibrium points; disease free and endemic equilibrium point. The qualitative results are depended on a basic reproductive number (R 0 ) . We obtained the basic reproductive number by using the next generation method and finding the spectral radius. RouthHurwitz criteria is used for determining the stabilities of the model. If R0 1 , then the disease free equilibrium point is local asymptotically stable: that is the disease will died out, but if R0 1 , then the endemic equilibrium is local asymptotically stable. Conclusion: Simulation results indicate that the numbers of susceptible individuals (S) be decreased after control strategies and also the number of infectious individuals (I) and infectious vector (Iv ) are decreased after control. 18 004-iciea Lithium-ion Battery Parameter Analysis Using Spectrogram Rizanaliah Kasim *1, Abdul Rahim Abdullah 2, Nur Asmiza Selamat 3, Nur Hazilina Bahari 4 and Mohd Zulkifli Ramli5 1,2,3,4,5 Universiti Teknikal Engineering,Malacca,Malaysia Malaysia Melaka(UTeM),Faculty of Electrical Abstract- Nowadays, energy storage improves the reliability and efficiency of electric utility system. The most common device used for storing electrical energy is battery. Obtaining an accurate data of battery parameter is important because it will be avoid unexpected system interruption and prevent permanent damage to the internal structure of the batteries. The objective of this study is to apply time-frequency distribution (TFD) which is spectrogram technique in analysis of voltage charging and discharging signal for lithiumion battery. Spectrogram represents the battery signal in time frequency representation (TFR) which is appropriate to analyze the signal before displaying the instantaneous RMS voltage (Vrms), direct current voltage (VDC) and alternating current voltage (VAC) parameter value. This paper focuses on lithium-ion (Li-ion) battery with nominal voltage of 6 and 12V and various storage capacities from 5 to 50Ah. The battery model is implemented in MATLAB/SIMULINK. From the results, the Li-ion battery parameter could be identified using spectrogram. 19 005-iciae Stability Analysis and Qualitative Behavior of Giving up Smoking Model with Education Campaign Thanawat Rittisak1 and Surapol Naowarat1,* 1 Department of Mathematics, Faculty of Science and Technology, Suratthani Rajabhat Unive rsity, Surat Thani,84100, Thailand Abstract- In this study, we proposed and analyzed a mathematical model to study the dynamics of giving up smoking and the effect of education campaign as a control strategy. The model is analyzed using stability theory of non-linear differential equations and is supported the results with numerical simulations. The results showed that there were two equilibrium points; smoking-free equilibrium point and smoking-present equilibrium point. The qualitative behavior results depend on the smokers reproductive number (R 0 ). We obtained the smokers reproductive number by using the next generation method. Stabilities of the model are determined by Routh-Hurwitz criteria. If R 0 <1 , then the smoking- free equilibrium point is local asymptotically stable, but If R 0 >1 , then the smoking-present 20 006-iciae equilibrium point is local asymptotically stable. The graphical representations are provided to qualitatively support the analytical results. It concluded that with an increase in the education campaign, the number of everyday smokers will be decrease.
