Electronic tax filing system or e-filing was introduced in Malaysia in 2006. It is one of the e-government applications that has the potential in ensuring the tax collection process efficiently. However, there are many excuses given by the taxpayers for not using the e-filing service provided by the government. Hence, taxpayer behavior really affects revenue collection for the country. The research postulates two objectives namely; to investigate the taxpayer's awareness on the availability of the electronic services offered by Lembaga Hasil Dalam Negeri Malaysia (LHDNM) and to analyse the feedback on the system. Data were collected using questionnaire adapted from Siegel's model known as electronic filing model of motivation (e-MAM), developed in 2008. The findings of the research show that respondents are aware of the services offered by LHDNM and they find the system easy to use and convenient.
电子报税系统于2006年在马来西亚推出。它是电子政务应用程序之一,在确保税收征收过程有效方面具有潜力。然而,纳税人有很多借口不使用政府提供的电子申报服务。因此,纳税人的行为确实影响着国家的税收。本研究设定两个目标,即;调查纳税人对马来西亚国家税务总局(LHDNM)提供的电子服务的可用性的认识,并分析对该系统的反馈。数据收集采用问卷调查改编自西格尔的模型被称为电子归档模型的动机(e-MAM),在2008年开发。调查结果显示,受访者了解LHDNM提供的服务,他们发现该系统易于使用和方便。

A gel polymer electrolyte composed of 30% PMMA grafted natural rubber (MG30), ammonium triflate (NH4CF3SO3) and ethylene carbonate (EC) as a plasticizer is described. The complexation between polymer and salt is observed by FTIR spectral studies. The band at 1728 cm-1 represents the C=O carbonyl group of MG30. The interaction is between the NH4+ cation and the oxygen atom of the C=O is confirmed since the IR spectrum show a shifting in the C=O stretching peak to lower wavenumber. The effect of plasticizer on the MG30-NH4CF3SO3 on the ionic conductivity is explained in terms of the plasticizer loading of the film. The temperature dependence of the conductivity of the polymer films obeys the Vogel-Tamman-Fulcher (VTF) relationship. The ionic transference number is calculated using Wagner's polarization technique shows that the conducting species are predominantly due ions and hence showed the system is ionic conductor.
介绍了一种由30% PMMA接枝天然橡胶(MG30)、三酸铵(NH4CF3SO3)和碳酸乙烯(EC)作为增塑剂组成的凝胶聚合物电解质。用红外光谱研究了聚合物与盐的络合作用。1728 cm-1处为MG30的C=O羰基。红外光谱显示C=O的拉伸峰向低波数偏移,证实了NH4+阳离子与C=O的氧原子之间的相互作用。从增塑剂在MG30-NH4CF3SO3薄膜上的负荷量来解释增塑剂对离子电导率的影响。聚合物薄膜电导率的温度依赖性服从Vogel-Tamman-Fulcher (VTF)关系。利用瓦格纳极化技术计算离子转移数,表明导电种类主要是由于离子,因此表明该体系是离子导体。

The objective of the study is to investigate the Corporate Social Responsibility (CSR) action and strategy used by the top 100 Malaysian Listed Companies followings the 1997 Asian's financial crisis. This research focus on Malaysian companies because Malaysia considered as one of the largest stock market in Southeast Asia countries. These studies utilize company's annual reports as a proxy for their CSR initiatives. As crisis has resulted negative impact to country and society, the result of the study shows that the economic crisis have motivated government and business to joint hand together to mitigate the impacts, as evident since 1920s i.e. after the Stock Market crash in United States and World War II. On the other hand, the crisis has also provide opportunity for the business to redirect away from a threat to an opportunity that differentiate them from the others. Furthermore, the study fairly explains legitimacy theory notions on the managerial actions from the Institutional lens namely "Institutional Legitimacy". Finally, apart from offerings descriptive contribution, our ambition is to assist future research on the post economic crisis particularly after the 2008 global economic crisis. This is because the state social structures, communities and people's ways of life were completely re-shaped after the economic changes.
本研究的目的是调查1997年亚洲金融危机后马来西亚100强上市公司的企业社会责任(CSR)行动和战略。本研究的重点是马来西亚公司,因为马来西亚被认为是东南亚国家中最大的股票市场之一。这些研究利用公司的年度报告作为其CSR举措的代理。由于危机对国家和社会造成了负面影响,研究结果表明,经济危机促使政府和企业共同努力减轻影响,自20世纪20年代以来,即在美国股市崩盘和第二次世界大战之后。另一方面,危机也为企业提供了机会,使其从威胁转向使其与众不同的机会。此外,本文还从制度视角,即“制度合法性”对管理行为的合法性理论概念进行了较为公正的解释。最后,除了提供描述性贡献外,我们的目标是协助未来对后经济危机的研究,特别是在2008年全球经济危机之后。这是因为在经济变革之后,国家社会结构、社区和人们的生活方式都被彻底重塑了。

Listeria monocytogenes subtyping is important in food processing environment or in epidemiological studies in order to identify the contamination sources and spreading routes, and to investigate the food-borne outbreaks. This study employs the combination of serotyping and random amplified polymorphism DNA (RAPD) analysis methods to characterize the isolated L. monocytogenes strains in food samples from local markets. Listeria antisera kit was used in serotyping which grouped L. monocytogenes isolates based on the expression of somatic and flagellar antigens. The L. monocytogenes serovars were further classified into RAPD types based on polymorphic banding patterns generated by using 10 random RAPD primers. The 23 isolated strains were divided into four different serotypes consisting 4b (43.5%), 1/2b (34.8%), 4d (8.70%) and 4e (4.35%) with two untypable isolates (8.70%). 11 banding patterns were obtained from each selected primer, OPA10 and OPA14 with DNA fragments ranging from approximately 0.15 kb to 1.1 kb. The constructed dendograms showed similarity percentage of 4% to 100% for OPA10, 12% to 100% for OPA14 and 4% to 100% for combination of primers. At a comparative genetic similarity of more than 90%, 21 distinguish RAPD profiles were obtained. The discriminatory of RAPD analysis method was proven as it could distinguish the isolates from the same serovar. However, between the two primers used, OPA14 provide better discriminatory results than OPA10 although it failed to type one isolate. These findings suggest that the application of RAPD analysis could be a useful tool in characterization of L. monocytogenes isolated from foods as it may provide important information on cross-contamination potential sites. Thus, the microbial monitoring should be applied and continuously performed in order to control listeriosis infection. The data may be useful for the food producers or epidemiological and public health studies of Listeria spp.
单核细胞增生李斯特菌分型在食品加工环境或流行病学研究中具有重要意义,有助于确定污染源和传播途径,调查食源性疫情。本研究采用血清分型和随机扩增多态性DNA (RAPD)分析相结合的方法对当地市场食品样品中分离的单核细胞增生乳杆菌进行鉴定。采用李斯特菌抗血清试剂盒对单核增生李斯特菌进行血清分型,并根据其体细胞抗原和鞭毛抗原的表达情况进行分组。利用随机选取的10条RAPD引物,进一步将单核增生乳杆菌血清型分为多态带型。23株分离菌株分为4b(43.5%)、1/2b(34.8%)、4d(8.70%)和4e(4.35%) 4种不同的血清型,2株未分型(8.70%)。从所选引物OPA10和OPA14中获得11个条带,DNA片段长度约为0.15 ~ 1.1 kb。构建的树形图显示,对OPA10的相似性百分比为4% ~ 100%,对OPA14的相似性百分比为12% ~ 100%,对引物组合的相似性百分比为4% ~ 100%。在比较遗传相似性超过90%的情况下,获得了21条可区分的RAPD谱。结果表明,RAPD分析方法可区分同一血清型的分离株。然而,在两种引物中,OPA14的区分效果优于OPA10,尽管它不能对一株分离物进行分型。这些结果表明,RAPD分析可以为食品中单核增生乳杆菌的鉴定提供重要的交叉污染位点信息,是一种有用的工具。因此,为了控制李斯特菌病的感染,应应用并持续进行微生物监测。这些数据对食品生产者或李斯特菌的流行病学和公共卫生研究有一定的参考价值。

In this paper, we report the electrical conductivity of nanocomposited MEH-PPV:I-MWNT thin film by varying the composition of Iodine doped multi-walled nanotubes (I-MWNT) in MEH-PPV matrix from 0, 2 and 4 wt%. Electrical conductivity showed increasing in value as the composition of I-MWNT increased from 0, 2 to 4 wt%. The value of conductivity is very outstanding when the polymer was blended with I-MWNT where the value rise from pure MEH-PPV, 81.6 × 10-4 S/m to 67.68 × 104 and 80.28 × 104 S/m for 2 and 4 wt% respectively. The surface morphology was investigated using atomic for microscopy (AFM). Roughness of the thin film showed decrement in value from 5.385 nm, 0.751 nm and 0.643 nm for 0, 2, and 4 wt% respectively. Meanwhile, the absorbance value increase slightly from about 0.16 (0 wt%) to about 0.165 and 0.17 (2 and 4 wt% respectively). The low absorbance shows that low photon is absorbed and therefore, there is no current changes when the sample is illuminated compared to in dark.
在本文中,我们通过改变碘掺杂多壁纳米管(I-MWNT)在MEH-PPV基质中的组成从0、2和4 wt%,报道了纳米复合MEH-PPV:I-MWNT薄膜的电导率。电导率随着I-MWNT的组成从0.2%增加到4%而增加。当聚合物与I-MWNT共混时,电导率值非常突出,从纯MEH-PPV的81.6 × 10-4 S/m上升到67.68 × 104和80.28 × 104 S/m,分别为2和4 wt%。用原子显微镜(AFM)研究了表面形貌。薄膜的粗糙度值分别从5.385 nm、0.751 nm和0.643 nm下降0、2和4 wt%。同时,吸光度值从约0.16 (0 wt%)增加到约0.165和0.17(分别为2和4 wt%)。低吸光度表明光子被低吸收,因此,与黑暗相比,样品在光照下没有电流变化。

Despite the advances in technology and increase of internet usage which provide numerous benefits to mankind, little is known about the problems and related issues such as the ethical issues and behavior of using the internet. Hence, it is crucial for researchers to study on the ethical issues relating to the use of information and communication technologies (ICT). This paper extends prior researches by investigating and exploring the use of ICT and ethical issues in Malaysian primary school. This study relates with four ICT issues proposed by Mason: privacy, accuracy, property and accessibility (known as the PAPA model). In this study, the quantitative methodology has been adopted by distributing questionnaires among students. The results indicated that the students are able to comprehend the ethical issues in the use of ICT.
尽管技术的进步和互联网使用的增加为人类提供了许多好处,但人们对诸如道德问题和使用互联网的行为等问题和相关问题知之甚少。因此,对研究人员来说,研究与信息通信技术(ICT)使用有关的伦理问题至关重要。本文通过调查和探索马来西亚小学使用ICT和道德问题来扩展先前的研究。本研究涉及梅森提出的四个ICT问题:隐私、准确性、属性和可及性(称为PAPA模型)。本研究采用定量研究方法,在学生中进行问卷调查。结果显示,学生能够理解使用资讯及通讯科技时的伦理问题。

Ranking of fuzzy numbers is an important procedure for many applications in fuzzy theory, in particular, decision-making. In this paper, we propose a new method for ranking fuzzy numbers based on Dice set theoretic index. The Hurwicz criterion which considers all types of decision makers' perspective is employed in aggregating the fuzzy total evidences. The properties of the proposed method are also presented. Five numerical examples are presented to illustrate the advantages of the proposed method. The ranking results show that the proposed method can overcome certain shortcomings that exist in the previous ranking methods.
模糊数排序是模糊理论中许多应用,特别是决策中的一个重要步骤。本文提出了一种基于Dice set理论指标的模糊数排序新方法。在模糊总证据的汇总中,采用了考虑了各类决策者视角的赫维奇准则。本文还介绍了该方法的特点。最后给出了5个数值算例,说明了该方法的优越性。排序结果表明,该方法克服了以往排序方法存在的一些不足。
