    It is hard to identify the local Malay identity in a design context compared to other cultural oriented design in several countries. This paper tries to uncover how designers interpret local identity embodied agent based on local items influences and understood and the influence of incremental, radical design that changes respective to preceding designs. A descriptive study through the literature reviews focusses on a type of artefact initiated through cultural-oriented design. Based on the preliminary study, a sampling taken from the Chinese, Indian, Japanese or European consistently apply the same fundamental understanding in regards to the culture-oriented design. From the same point of view, teapot seems to be used as one of the dominant artefact indicating the design preferences. This research will benefit both the academia and the industry and identify significant identity based on the local context and become an embodied agent to give impact in establishing the state-of-the-art of brand, the identity of local design, establish new trademark towards generating domestic, international economy and promote the nation worldwide throughout design platform.

    The aim of this paper is to review the potentialities and major methodological challenges
    of integrating remote sensing (RS) and geographic information system (GIS) with socioeconomic data
    from published articles or book chapters. RS and GIS combined with social science (SS)(termed as
    geoinformation technology) serve many applications for sustainable management and monitoring of
    the environment. This combined approach gives more accurate results than the single one. It makes
    information available about the trend and pattern of land use and land cover change (LUCC) with
    socioeconomic variables like population, demographic or income. This combined study which links
    RS and GIS with socioeconomic data can also be used successfully for monitoring transmission rate
    of disease and mapping or preparing vulnerability index. For impact assessment and modelling, this
    combined technology provides better results than the single one. There are some methodological
    problems for the researchers to link completely two different disciplines as the object of study and
    observational unit is completely different. However, this interdisciplinary study is gaining popularity
    day by day to researchers from different disciplines as well as decision makers.

    Ergogenic aids usage by athletes is a common scenario that can be seen in any level of athletes and any types of sports nowadays. Ergogenic aids can range from drugs, food, hormone, mechanical aid and herbs. Traditionally, ergogenic aids can be classified into categories namely: physiological, psychological, mechanical, pharmacological and nutrition. Despite all these classification, all ergogenic aids had one common purpose, which is to improve physical performance. Herbs consumption as ergogenic aids had been practiced since years ago by athletes as either nutritional or pharmacological aids. Using herbs as physical performance booster has gained popularity since it was claimed safer and natural. One of local herb that gets attention as energy booster is Ficus deltoidea (Mas Cotek). Ficus deltoidea had been used traditionally to restore energy. Few studies had reveal that Ficus deltoidea had medicinal properties such anti-nociceptive, antioxidant, wound healing enhancer and blood glucose regulation properties. There is no direct study on Ficus deltoidea as energy booster or ergogenic aids, but this medicinal value might be beneficial to increase athlete’s physical performance. Ergogenic aids, especially those that been produce using herbs, rarely have scientific evidence to determine its effectiveness, safety, dosage and mechanism of action. Ergogenic aids were normally marketed with claims and report as their reference, not scientific evidence. The most frequent claim used by traders is that ergogenic aids can increase and sustain body’s energy. This review will discuss on how ergogenic aids might help athletes to increase their physical performance and possibility of using Ficus deltoidea as ergogenic aids based on its medicinal properties.

    Stevia rebaudiana Bertoni in the Asteraceae family is commercially valuable and cultivated throughout the world due to the great demand for its steviol glycosides (SGs) contents particularly rebaudioside A. Previous studies confirmed that maximal content of SGs in stevia was achieved at or just before flowering, and delayed flowering with long days provide longer duration for steviol glycosides accumulation. However, there is no suitable stevia variety to be cultivated in Malaysia due to her short day length. Mutation induction, including gamma irradiation, had been shown to be useful for generating genetic variations as well as developing new plant varieties from which desired mutants were successfully selected. The use of mutagens, both physical and chemical, has helped in creating mutants that expressed the selected desirable traits. This paper presents some selected essential data available in extant scientific studies on stevia with the focus on application of gamma irradiation on stevia. Both established achievements and recent publications of gamma radiation on stevia were reviewed. Emphasis is on the exceptional potential of stevia through induced mutation approach especially by using gamma rays.

    Torque Teno Virus (TTV) is a human-infected virus that is present ubiquitously in nature. Globally, it infects up to 95% of the healthy individuals without any clinical manifestations. The widely used laboratory diagnosis of TTV infection is Polymerase chain reaction (PCR). Nevertheless, several other methods have been developed. The rapid growth of TTV variants over time has posed a challenge in estimating the global TTV infection as none of the PCR protocol has the ability to detect the entire spectrum of TTV variants. Multiple TTV epidemiological studies have been conducted among Asian population, whereas other continents showed a limited number of studies. The horizontal and vertical transmission of TTV among humans population, as well as interspecies transmission are potentially related to the global widespread of TTV infection.

    Isoprenoids biosynthesis in plants involves two separate pathways, mevalonate (MVA) pathway and 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway. A large group of isoprenoids are found to play crucial roles in common plant biochemical functions and have been produced on a large scale for commercial applications. 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is the key enzyme that catalyses the first committing step in the MVA pathway. In mammals and yeast, HMGR is a well-studied enzyme as many studies have been done on this enzyme due to its important function in the biosynthesis of cholesterol. In plants, many researches on HMGR have been done on different plant species, for example, Arabidopsis thaliana, tobacco, gingko, Zea mays, potato, rose, rubber tree, muskmelon, ginseng and others, in the past decades since it was discovered. Previous researches that worked on plant HMGR focused on the cloning and characterisation of its physiological functions. Little is known about the aspect of regulation and structural characteristics of plants’ HMGR. This review is aimed at providing an overview of the characteristics and structure of HMGR, the transcriptional and post-translational events related to HMGR that have been reported in plants, and proposes areas on the regulation event of HMGR in plants that can be explored to further enhance understanding towards HMGR regulatory interactions.

    The use of remote sensing in detecting aerosol or air pollution is not widely applied in Malaysia. The large area of coverage provided by remote sensing satellite may well be the solution to the lack of spatial coverage by the local ground air quality monitoring stations. This article discusses the application of remote sensing instruments in air quality monitoring of Malaysia. The remote sensing data is validated using ground truths either from local ground air monitoring stations or the Aerosol Robotic Network (AERONET). The correlation between remote sensing is relatively good with R from 0.5 to 0.9 depending on the satellite used. The correlation is much improved using the mixed effects algorithm applied on MODIS Aerosol Optical Depth (AOD) data. Accuracy of predicted air quality data by remote sensing is generally tested using the Root Mean Squared Error (RMSE) against the ground truths data. Besides the Geographic Information System (GIS) tools are used in manipulating the data from both remote sensing and ground stations so as to produce meaningful results such as spatio-temporal pattern mapping of air pollution. Overall the results showed that the application of remote sensing instruments in air quality monitoring in Malaysia is very useful and can be improved further.

    The utilization of bamboo as a manufacturing material is becoming globally attractive in
    the wood and wood product industries today. This is due to the numerous industrial applications and
    uses of the bamboo plant from its fast growth, availability, unique appearance and strength. Bamboo
    has been popularly known for its traditional uses such as poultry cages, vegetable baskets, incense
    sticks, skewers and chopsticks, woven blinds and handicrafts. Very little has been done on the
    industrial processing of bamboo into boards. Several authors have studied and reported on the
    utilization, processing and the properties of this emerging material as an alternative to the increasing
    decline of wood in the forest. This review aims to compare and contrast some of the works done on
    the advancement in producing laminated bamboo timber. The properties of bamboo and its laminated
    products attest to its potency in substituting wood. Bamboo utilisation has increased significantly in
    the wood and wood product industries, with adequate retooling in most processing firms in the sector.
    In line with the development and use of bamboo-laminated timber for the purpose of wood in
    furniture production, the creation of bamboo plantations on degraded lands will meaningfully support
    production and mitigate the degradation of forest.

    Recently, the contamination of heavy metals towards the environment especially in aquatic system has drastically increased. Heavy metals are able to transform into persistent metallic compound in which it can be accumulated within the organisms’ body system, disrupting the food chain and eventually threatened the human life. The occurrence of heavy metals spillage in the rivers and lakes are due to the careless disposal of excess heavy metals used for human activities. The accumulation of heavy metals in water system will affect all aquatic organisms especially fish. The toxicity of copper in fish can be determined by several changes in the fish under treatment with heavy metals sub-lethal concentration, LC50 within 96-hours period of acute exposure. Therefore, fish can be considered as a high potential biomarker for monitoring heavy metals pollution in aquatic system. Several selective organs are highly sensitive to the xenobiotic pollution and express changes to the exposure. One of the most potential biomarker is the biochemical biomarker of cholinesterase (ChE) inhibition by heavy metals in fish has been well studied in pollution monitoring recently. Thus, this paper gives an overview of the manipulation of fish as a biomarker of heavy metals through enzymatic reaction which have proven to be very useful in the environmental pollution monitoring.

    Citrus bent leaf viroid (CBLVd) from genus Apscaviroid, is one of the widely distributed viroids among the seven citrus viroids. It is comprised of three variants: Citrus viroid-Ia (CVd-Ia) (327 - 329 nucleotides), Citrus viroid-Ib (CVd-Ib) (315 - 319 nucleotides) and Citrus viroid-I-low sequence similarity (CVd-I-LSS) (325 - 330 nucleotides). Virulence of CBLVd totally expressed on citrus plants. Etrog citron (Citrus medica (L.)) coinfected with CBLVd, Citrus exocortis viroid (CEVd), Citrus viroid-III (CVd-III) and Citrus viroid-V (CVd-V) showed epinasty, leaf rolling, and stunting. CBLVd has been reported to reduce the canopy proportion and fruit production of citrus trees inserted on trifoliate orange rootstock. Moreover, citrus tree infected with singly CBLVd or in combinations with CEVd, Hop stunt viroid (CVd-II) and CVd-III induced dwarfing have been associated with poor development of the root system. Reverse-transcriptase polymerase chain reaction (RT-PCR) amplification and multiplex reverse-transcriptase polymerase chain reaction (MRT-PCR) amplification have been widely used to detect citrus viroids including CBLVd. As citrus viroids are emerging threats in citrus groves, therefore, this review covers the evolution, geographical distribution and epidemiology, economic impact and symptomatology, host range and transmission, detection, and management will be helpful in formulating the integrated management strategies for CBLVd.

    Language is essential for communication. People who are involved in cross cultural communication have to be bilingual in order to interact with people from a different language background (Blackwell. Woolard, K. (2005). Bilingualism opens up various new pathways of thoughts, expressions, and it helps to reduce misunderstanding in interactions (Hidayat, T. 2012). The purpose of this review is to find out how code-switching plays a vital role in language communication especially in the social media such as Facebook, Twitter, SMS and Chat. This study reviewed fifteen journal articles to examine the ways code-switching was used. The review was to discover social phenomena and authentic identities of social actors. The study discovered that code-switching has been used widely to unmask bilinguals’ cultural background and group identity during online communication via Facebook. Finally, code-switching can be used to obtain positive feelings to the interlocutor, which here was combined with introducing humour as an in-group marker, quoting, and to some extent topic specificity as well as possible vocabulary limitation in one language or the other, in the online conversation by bilinguals such as to express group solidarity.

    Edible bird’s nest (EBN) originates from South East Asia and has become the most popular food delicacy among Chinese people. The price for raw and clean EBN are around RM 4,000 and RM 8,000 per kg, respectively. Due to the high market value of EBN and low maintenance cost, people ventures and invest in bird’s nest industry. The nesting house resembles the cave is built to attract swiftlets to roost and nest in it in order to meet the world’s growing demand. Out of the blue, in 2011, the EBN’s price falls half from its original price from RM 4,000 to RM 2,000. Nitrate found in raw or unclean EBN is one of the reason price plunges and the public also worried about counterfeit EBN that made from unclear substances. Thus, this review paper aims to highlight the nutritional properties in EBN that give medicinal benefits to consumers and the adulterant in EBN to increase the property contents with the dangerous mechanism by some irresponsible producers to obtain better profit which can threatening public’s health. In relation, these matters may influence consumer’s perception on EBN contents that could harm this industry. For that reason, scientific studies determined ways of handling EBN from scratch and distinguished the adulterant in EBN to reduce consumer anxiety was also discussed. Strict standard operation procedure enforces by the Malaysian Ministry of Health to farmers and producers are required, so that Malaysia EBN would appeal to the China market. Latter it can yield a good result and the price of EBN will slowly increase.

    Small and medium scale enterprises (SMEs) act as a promoter of economic development of the developed and under developed nations. Developing countries like Nigeria that, require sustainable economic growth and development must pay attention to the SMEs sectors in order to reduce unemployment, poverty and improve the standard leaving of its society. Unfortunately, in Nigeria, SMEs have underperformed despite that, 90% of the Nigerian businesses are small scales but their contribution to the Nigerian GDP is below 10%. The main reason for this low contribution of SMEs to Nigerian GDP could be attribute to poor funding, lack of management expertise and lack of access to modern technology among others, with proper finance the SMEs can acquire modern technology and employed qualified staff. Thus, this paper focuses on crowdfunding as financial option for Nigerian SMEs. However, the paper is a conceptual framework.

    Transition metals are required constituent in bacterial metabolism to assist in some enzymatic reactions. However, intracellular accumulations of these metal ions are harmful to the bacteria as it can trigger unnecessary redox reactions. To overcome this condition, metalloregulatory proteins assist organisms to adapt to sudden elevated and deprived metal ion concentration in the environment via metal homeostasis. CsoR protein is a copper(I) [Cu(I)] sensing operon repressor that is found to be present in all major classes of eubacteria. This metalloregulatory protein binds to the operator region in its apo state under Cu(I) limiting condition and detaches off from the regulatory region when it binds to the excess cytosolic Cu(I) ion, thus derepressing the expression of genes involved in Cu(I) homeostasis. CsoR proteins exist in dimeric and tetrameric states and form certain coordination geometries upon attachment with Cu(I). Certain CsoR proteins have also been found to possess the ability to bind to other types of metals with various binding affinities in some Gram positive bacteria. The role of this metalloregulatory protein in host pathogen interaction and its relation to bacterial virulence are also discussed.
