    Substance abuse is an epidemic that spreads among adults, adolescents and even children in Malaysia. Substance abuse is categorized as a mental disorder, whereby, Cognitive Behavioural Therapy (CBT) is an approach that provides face to face physiological therapy for patients could resolve this issue. Computerized Cognitive Behavioural Therapy (CCBT) is a progression of information technology that is provided for patients encounter substance abuse. CCBT is a computerized therapy conducted at patient’s own pace. Ensuring patient’s continuous engagement towards CCBT becomes an issue. Patients that experience early gains, loss of interest and improvement symptom would sign up for alternative services that eventually causes disengagement and dropout from CCBT program. Interface design for CCBT is known as one of the important elements that effects patient’s engagement along CCBT program. Therefore, in this study, influential factors regarding CCBT’s interface design was investigated, whereby, five prominent models was reviewed. Content analysis methodology was employed to discover influential factors regarding CCBT’s interface design. Four influential factors was discovered namely engagement, dropout, culture and interface.

    The contamination of water bodies from heavy metals, either from natural sources or
    anthropogenic sources, has become a major concern to the public. Industrial activities with improper
    water treatment, and then leach into the water body, have become contaminated and harmful to
    consume. Passive remediation is one of the treatments introduced to counter this problem as it is a low
    cost but effective technique. After being widely acknowledged and through research conducted, the
    most suitable remediation technique found is the permeable reactive barriers (PRBs). PRB is defined
    as an in situ permeable treatment zone filled with reactive materials, designed to intercept and
    remediate a contaminant plume under natural hydraulic gradients. There have been many findings
    made from PRB which can be used to remove contaminants such as heavy metal, chlorinated solvents,
    carbonates and aromatic hydrocarbons. The most crucial criteria in making a successful PRB is the
    reactive media used to remove contaminants. The current paper presents an overview of the PRB
    selective medias that have been used and also the unresolved issue on the long term performance of
    PRB. The overall methodology for the application of PRB at a given site is also discussed in this
    paper. This inexpensive but effective technique is crucial as a sustainable technology in order to treat
    the drainage before it enters water tables to prevent water pollution and can be used as an alternative
    raw water source.

    Improving rice production is of current global concern so that food security is maintained especially in developing nations where rice remains as the staple food. With the aid of molecular biology, various isolated genes conferring to abiotic, biotic and herbicide stress tolerance has been successfully transferred into rice. Attempts have also been made to enhance grain yield, nutritional characteristics, fragrance and photosynthetic capacity of rice. The success of a commercialized transgenic rice largely depends on the biosafety and environmental risks assessments as these information translates into consumers’ acceptance towards genetically modified (GM) rice. As the renowned Golden Rice has received the green light for field trial in the Philippines and Bangladesh, this would serve as a catalyst for better acceptance of GM food crops. A brief case study on the commercialization of transgenic BT rice in China will also be discussed. The review aims to bring useful insights for future endeavors in improving traits for rice through genetic engineering.

    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.

    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.

    Canarium odontophyllum Miq. fruit, popularly recognized as dabai fruit in Sarawak, is a
    seasonal fruit found in the tropical rainforest of East Malaysia. A dabai fruit can be divided into
    several anatomical parts, and different parts of the fruit have different valuable phytochemicals. Due
    to the lack of promotion, dabai fruit is viewed as nutritionally inferior fruit by the public. On the
    contrary, the fruit is rich in nutrients such as protein, fat, carbohydrates, sodium, calcium and iron.
    Many phytochemicals have been detected from different parts of dabai fruit, and these molecules have
    been linked to beneficial properties such as hypolipidemic, anti-atherosclerotic, anti-cholinesterase,
    antimicrobial and potentially anti-diabetic. The aim of this article is to review research studies on this
    fruit in order to provide adequate baseline information for commercial exploitation as well as for
    future studies.

    This paper discusses the three most prevalent elements of Islamic art that a r e embedded in modern furniture. This study is isolated from three design thinking approaches. A comparative study has been executed between three most apparent elements of Islamic art, which are arabesque, geometric and calligraphy. Those three types of design are applicable and relevant to modern furniture design nowadays. Therefore, the Islamic model was the paradigm in defining the furniture design character. The unstructured parameter within the appropriate method is a significant way of collecting the findings and usually used in the area of furniture design. The main results of this study are on how Islamic pattern is linked with the artistic design elements. The outcome of this investigation also contributes to a significant tendency in contemporary furniture design thinking solutions. Finally, this paper ends with discussions from three types of design thinking, which is the normative, reflective and hermeneutic design that collaborates with the current modern furniture design.

    The purpose of this article is to illustrate the links between the three factors of parental attachment (i.e., communication, trust, and alienation) and cyberbullying experiences among school- going children. A total of 375 students aged 9 to 16 years old were selected using stratified sampling method from 8 schools in Selangor. The authors adapted a 10-item instrument from the previous studies of Youth Internet Safety Survey (YISS) and EUkidsonline scales to assess the cyberbullying prevalence based on two sub-dimensions (online harassment and sex-based bullying). The confirmatory factor analysis (CFA) was used to analyse the construct validity of the scales. Structural equation modelling (SEM) then was used to test the study hypotheses. The final model has an estimated that 10% (R2=.95) of the variance in cyberbullying is explained by parental attachment, indicating only the alienation factor predicted the children’s cyberbullying experiences. The findings, however, supported a differentiated approach to positive parenting.

    Ki-67 expression is strongly correlated with tumour cell proliferation and growth. It is widely used as a proliferation marker in the routine pathological investigation. The nuclear protein Ki- 67 (pKi67) is recognised prognostic and predictive indicator for the biopsies assessment for cancer patients. Clinically, pKi67 has been revealed to associate with metastasis and the clinical stage of tumours. Furthermore, it has been presented that the expression of Ki-67 is significantly higher in malignant tissues with poorly differentiated tumour cells, as compared with normal tissue. The Ki-67 labelling index plays a vital role as an independent prognostic factor for survival rate, which includes all stages and grade categories. There is an association between the ratios of Ki-67 positive malignant cells and patient survival. This review provides an overview of recent advances in detecting Ki-67 in ovarian carcinoma.

    Burkholderia pseudomallei are Gram negative highly pathogenic bacteria of humans and
    animals causing a multisystemic disease called melioidosis. They have recently gained a lot of interest
    from the research community and public health organisations because of their great potential to be
    used as an agent of bioterrorism. This has made the search for simple, rapid, accurate and the most
    definitive means of their detection, identification and discrimination very critical and necessary. This
    article aimed to review the molecular techniques used for detection, identification and differentiation
    of B. pseudomallei. Although, culture and isolation techniques maintained their usefulness in
    confirming cases of melioidosis, their time limitation (can take up to a week for confirming diagnosis)
    leads to the search for rapid and simple techniques. Consequently, serology-based tests have been
    developed which are both faster and less sophisticated. However, the presence of high background
    titre levels and cross-reaction with other organisms make it less reliable. Thus, efforts have been
    directed to explore rapid and accurate molecular techniques and resulting in the development and
    validation of various PCR-based identification techniques targeting either single or multiple genes.
    Although requiring some level of instrumentation and expertise, PCR-based techniques have been
    reported to be very useful in diagnosis of melioidosis. We recommend the 16S rRNA PCR (especially
    augmented with other molecular methods such as gene sequencing and analysis) and MLST
    techniques for timely detection, identification and differentiation of B. pseudomallei for routine
    diagnosis and epidemiological studies respectively.

    This paper presents an evaluation of the alternative use of natural cellulose coir fibres for
    soil reinforcement. Soil reinforcement is defined as a technique to improve the engineering properties
    of soil. Inserting natural fibres into the soil has been proposed as a reinforcement method. Randomly
    distributed coir fibre reinforced soils have recently attracted increasing attention in geotechnical
    engineering due to their strength. Furthermore, there is a need to develop an innovative and
    sustainable pre-treatment method to improve the effectiveness and performance of coir fibre as soil
    reinforcement. The primary purpose of this paper is, therefore, to review the characteristics, benefits,
    applications and weaknesses of coir fibre as soil reinforcement.

    Nitric oxide (NO) is a signaling molecule involved in numerous physiological processes in
    both animals and plants. The bioactivity of NO is mainly transduced via post-translational modification
    of cysteine residues of proteins termed S-nitrosylation. Interestingly, a number of key regulatory
    components in plant defense responses have been found to be regulated by S-nitrosylation making this
    type of protein modification an important modulator of plant immunity. As a signaling molecule, NO
    intimately interact with other important molecules such as reactive oxygen species. Since the
    identification of NO in plants, increasing number of papers isbeing published in the area of NO biology
    each year. Here, a collection of papers describing the role of NO in plant immunity has been brought
    together to provide a bird's-eye view on the focus area.

    Facility Layout Problem (FLP) is a NP-hard problem concerned with the arrangement of facilities as to minimize the distance travelled between all pairs of facilities. Many exact and approximate approaches have been proposed with an extensive applicability to deal with this problem. This paper studies the fundamentals of some well-known heuristics and metaheuristics used in solving the FLPs. It is hoped that this paper will trigger researchers for in-depth studies in FLPs looking into more specific interest such as equal or unequal FLPs.
