The government’s science and technology (S&T) apparatus is now in active consultation to formulate the third national S&T policy (NSTP3) and I have been involved in some of these meetings and have benefitted from them. In an earlier article (New Straits Times, 9 July 2011, p. 18) I had briefly described the two previous policies and given some thought on what the essentials of the NSTP3 should be. I am now offering some further thoughts on the subject. (Copied from article).
This paper presents the solution to a calculation of the pH of a very dilute solution of a strong acid or base, taking into account the effect of the hydronium or hydroxyl ions generated from the ionisation of the strong acid or base on the ionisation of water, as a second very weak acid. To be solved successfully, this calculation involves the concepts of conservation of charge, pH and the application of the general solution to a quadratic equation. Such an exercise involves the application of skills in basic numeracy, and can provide a core of understanding that can prepare students for
many different sorts of calculations that represent reallife problems in the medical and biological sciences.A programme is presented in C++ which enables the work of students to be individualised so that each student in a class can work through a slightly different pH calculation, in such a way that a class supervisor can quickly check each student’s result for accuracy. This exercise is presented as a potential means of enabling students to undertake and master similar types of calculations involving simple or more complex equilibria.
Evaluating scientific quality of a journal is a notoriously cumbersome problem that so far no standard consensus. Preferably, scientific journals should be examined by real experts in the field and given scores on quality according to standard guidelines. Nevertheless, information scientists (i.e. scientometricians) have developed a diverse range of tools to examine scientific merits of scientific publications that mainly depending on various indexes that counting citations. The impact factor (IF) is commonly used to examine the visibility of a journal. It is the average number of citations a paper of a journal attracts in the two years following its publication.
Sports engineering can be considered as a new engineering discipline. It bridges the gap between two distinctive fields: sport science and engineering. Sports engineers are responsible in designing and building new equipment based on athlete's demands, besides measuring the performance of the athlete, the equipment itself, as well as their interaction. It is without doubt that engineering and technology have played an important role not only in improving the performance of an athlete, but also in making sports more entertaining and safe. This article provides an insight into how engineering and technology have affected sports in many ways transforming it from just a past time to more exciting and competitive world events. Apart from the impact of engineering in sports, the history of the application of engineering and technology in sports is also elaborated. Furthermore, research conducted in related fields worldwide is highlighted. A brief overview of sports engineering research in Malaysia is also presented.
The advancement of technology has allowed a variety of tools for employees and
managers, or knowledge workers, to choose as communication tools, especially for
managing project teams. Instead of communicating and updating project progress
through emails and short messaging system, social messaging (SM) applications, such
as WhatsAppTM, are the current daily choice among them. The over-utilisation of the
SM applications has given an opportunity for a research on project knowledge
retention within project team, since it becomes an addiction to create new groups each
time a new project team is formed. It is believed that project knowledge resides within
these virtual groups, and this paper looks into how project knowledge is managed by
analysing the communication patterns against a measurement metrics based on
personal knowledge management (PKM) theory called GUSC Model. The
communication patterns found existed in the SM application are qualitatively
identified and mapped against the PKM processes within, with weighted score
assigned to each process to quantitatively measure the overall project knowledge
management participation. The differences among the organisational communication
levels, namely upper and lower level communication levels, are analysed and the final
result of participation expectation on member of SM application groups is presented.
The outcome of this research recommends the future intervention on SM application
usage and the application of knowledge management concept in current
communication tool.
A study was conducted to examine the usage of application software and its development practices in Malaysia. The study has shown that the use of application software is greatly emphasized by organizations in their respective businesses. And for most organizations, the application software is supplied by a vendor or through in house development. For the software development practices, the deployment of a current technique and technology is still inadequate. Therefore, most of the existing information technology practitioners should be given additional training on the latest techniques of software development. Other aspect of improvement on software development practices is also discussed.

Fake and unethical publishers' activities are known by most of the readers of Science and Engineering Ethics. This letter tries to draw the readers' attention to the hidden side of some of these publishers' business. Here the black market of scholarly articles, which negatively affects the validity and reliability of research in higher education, as well as science and engineering, will be introduced.
Research has tremendously contributed to the developments in both practical and fundamental aspects of limb prosthetics. These advancements are reflected in scientific articles, particularly in the most cited papers. This article aimed to identify the 100 top-cited articles in the field of limb prosthetics and to investigate their main characteristics. Articles related to the field of limb prosthetics and published in the Web of Knowledge database of the Institute for Scientific Information (ISI) from the period of 1980 to 2012. The 100 most cited articles in limb prosthetics were selected based on the citation index report. All types of articles except for proceedings and letters were included in the study. The study design and level of evidence were determined using Sackett's initial rules of evidence. The level of evidence was categorized either as a systematic review or meta-analysis, randomized controlled trial, cohort study, case-control study, case series, expert opinion, or design and development. The top cited articles in prosthetics were published from 1980 to 2012 with a citation range of 11 to 90 times since publication. The mean citation rate was 24.43 (SD 16.7) times. Eighty-four percent of the articles were original publications and were most commonly prospective (76%) and case series studies (67%) that used human subjects (96%) providing level 4 evidence. Among the various fields, rehabilitation (47%), orthopedics (29%), and sport sciences (28%) were the most common fields of study. The study established that studies conducted in North America and were written in English had the highest citations. Top cited articles primarily dealt with lower limb prosthetics, specifically, on transtibial and transradial prosthetic limbs. Majority of the articles were experimental studies.
Recently, the zebrafish has gained in popularity as a vertebrate animal model for biomedical research. Commercial zebrafish housing systems are available and are designed to maximize stocking density of fish for a given space, but these systems are expensive and purchasing them may not be feasible for emerging laboratories with limited funding. In this article, we describe the construction of a simple and affordable recirculating zebrafish housing system. This system can be constructed in 3 working days, with materials readily available in hardware stores. The cost for construction of the system was only 3,000 MYR (750 USD). The system consists of a water reservoir, a supply line that delivers water to the shelves holding the zebrafish tanks, and a drainage line that receives water from both the supply line and the shelves containing the fish tanks and returns this water to the reservoir. This system also has a 3-stage filtration process to ensure that clean water is delivered to the zebrafish tank. The system can house up to 360 zebrafish. This low-cost housing system may make research using zebrafish feasible some laboratories.
The research mentorship programme is unique in that it is a planned journey undertaken by the mentor and mentee, preferably with well-defined milestones along the journey. During the journey, familiar landmarks will be pointed out by the mentor. In path-finding situations the experience and wisdom of the mentor and the critical appraisal of both mentor and mentee will contribute to learning from the encounter. In most mentor-mentee partnerships, a formal acceptance to the relationship, well-defined landmarks measuring progress in the journey, regular appraisal of the skills developed and acquired, and phased, judicious modification in the individual roles of that relationship will be required. Although there is no consensus on the elements of mentorship, there are some strategies which can contribute to the success of the relationship. Critical success factors include convergence of the research area within the broad expertise of the research mentor. The research mentor should have a proven research track record and is committed to serve in that official capacity. The research mentoring process is dynamic and characteristics of both mentor and mentee contribute to the robustness of that relationship. The mentee would have identified some attributes of the mentor that are desirable and is willing to work hard to achieve, build on, and improve upon. In the research setting endpoint measurements of success will be based on recognition of the research standing of the mentee, measurable outcomes such as number of papers in top tier journals, citation indices, etc. consultancies attracted as well as invitations to deliver plenaries in scientific conferences, patents filed and research findings translated and applied, and other measures of research productivity. In the pursuit of research excellence the mentee would have imbibed values of professionalism and ethics in research and would have constantly kept in mind that to be successful, the mentee would be able to excel beyond his mentor and that the next generation of researchers will seek mentorship from him.
Cloud computing has attracted significant attention from research community because of rapid migration rate of Information Technology services to its domain. Advances in virtualization technology has made cloud computing very popular as a result of easier deployment of application services. Tasks are submitted to cloud datacenters to be processed on pay as you go fashion. Task scheduling is one the significant research challenges in cloud computing environment. The current formulation of task scheduling problems has been shown to be NP-complete, hence finding the exact solution especially for large problem sizes is intractable. The heterogeneous and dynamic feature of cloud resources makes optimum task scheduling non-trivial. Therefore, efficient task scheduling algorithms are required for optimum resource utilization. Symbiotic Organisms Search (SOS) has been shown to perform competitively with Particle Swarm Optimization (PSO). The aim of this study is to optimize task scheduling in cloud computing environment based on a proposed Simulated Annealing (SA) based SOS (SASOS) in order to improve the convergence rate and quality of solution of SOS. The SOS algorithm has a strong global exploration capability and uses fewer parameters. The systematic reasoning ability of SA is employed to find better solutions on local solution regions, hence, adding exploration ability to SOS. Also, a fitness function is proposed which takes into account the utilization level of virtual machines (VMs) which reduced makespan and degree of imbalance among VMs. CloudSim toolkit was used to evaluate the efficiency of the proposed method using both synthetic and standard workload. Results of simulation showed that hybrid SOS performs better than SOS in terms of convergence speed, response time, degree of imbalance, and makespan.
Cancer research is an extremely broad topic covering many scientific disciplines including biology (e.g. biochemistry and signal transduction), chemistry (e.g. drug discover and development), physics (e.g. diagnostic devices) and even computer science (e.g. bioinformatics). Some would argue that
cancer research will continue in much the same way as it is by adding further layers of complexity to the scientific knowledge that is already complex and almost beyond measure. But we anticipate that cancer research will undergo a dramatic paradigm shift due to the recent explosion of new discoveries in cancer biology. This review article focuses on the latest horizons in cancer research concerning cancer epigenetics, cancer stem cells, cancer immunology and cancer metabolism.

He returned to earth, landing safely on 21 October 2007. Such a momentous event has carved out yet another milestone in the country’s
history and development of a civilisation based on science and technology for its people. This mission has provided the educational sector with an opportunity to initiate a curriculum innovation. Together with the Ministry of Education (MOE), the initiative was undertaken to improve techniques of teaching and learning (TL) and to broaden its scope to include space science and technology.
Swiftlet
s
are small insectivorous birds which breed throughout Southeast Asia and
the South Pacific.
Among many swiftle
t species, only a few are notable to produce edible bird’s
nest
s
(EBN) from the secreted saliva during breeding seasons.
The taxonomy of swiftlet
s
remains one of the most controversial in the avian species due to the high similarity in
morphological charac
teristics among the species. Over the last few decades, researchers have
studied the taxonomy of swiftlet
s
based on the morphological
trade
, behavior, and genetic
traits
.
However, despite all the efforts,
the
swiftlet taxonomy remains unsolved.
The
EBN is one of
the
most expensive animal products
and frequently being referred
to
as the “
Caviar of the East
”.
The
EBN market value varies from
US
$1000.00 to
US
$10,000.00 per kilogram depend
ing
on
its grade, shape, type and origin.
Hence, bird’s nest harve
sting is considered a lucrative industry
in many countries in Southeast Asia.
However,
the
industry faced several challenges over the
decades such as the authenticity of the EBN, the quality assurance and the depletion of swiftlet
population. Furthermore,
there is limited scientific evidence regarding EBN’s medical benefits
as
claimed by manufacturers. This paper reviews the taxonomy of swiftlet
s
, its morphological
characteristics, the challenges currently encountered by the industry, and finally the
compos
ition and medical benefits of EBN.
Rapid progress of Information Communication Technology (ICT) will accelerate the distribution of
information from government to the people; however the monopoly of technology ICT services will
lead to inequality of information distribution in between of normal people and disabled people.
Embrace with the inequality of ICT distribution directly make the group of disabled people left behind
at the information age, or the situation also known as digital divide. Hence, this article attempts to
identify and examine the issues facing by disabled people in order to catch up the fast diffusion of ICT.
One of the most important lifetime distributions that is used for modelling and analysing data in clinical, life sciences and engineering is the Weibull distribution. The main objective of this paper was to determine the best estimator for the two-parameter Weibull distribution. The methods under consideration are the frequentist maximum likelihood estimator, least square regression estimator and the Bayesian estimator by using two loss functions, which are squared error and linear exponential. Lindley approximation is used to obtain the Bayes estimates. Comparisons are made through simulation study to determine the performance of these methods. Based on the results obtained from this simulation study the Bayesian approach used in estimating the Weibull parameters under linear exponential loss function is found to be superior as compared to the conventional maximum likelihood and least squared methods.
