International Journal of East Asian Studies, 2016;5(1):1-13.
MyJurnal

In 1994, the Government of Malaysia received 61.518 million yen to commence Kuala Lumpur
International Airport (KLIA) project. The airport is located in the district of Sepang, Selangor, which
was originally oil palm plantations and small villages. The construction project completed and began in
used in the 1998. This paper is to evaluate the impact of Japan's ODA for Malaysia, particularly yen
loan to socioeconomic. In term of socioeconomic impact, many new cities were established such as
Bandar Baru Salak Tinggi, Bandar Baru Nilai, Banting, Bandar Enstek and Cyber Jaya. Similarly, new
housing, schools, shopping malls and other facilities such as the Sepang International Circuit and
Universiti Sains Islam Malaysia (USIM) were built. New roads connecting to the airport also completed
the development of these places. In terms of employment, previously many who depended on agriculture,
now turned to business, hospitality, services, transportation and others. In fact the huge investment
significantly affected the surrounding population, particularly the creation of modern towns, businesses
and educational centers which gave rise to various types of employment.

Fulltext Work related injury and illness: exploring the return-to-work program in Malaysia

Awang H, Mansor N, Rodrigo SK

Southeast Asian J. Trop. Med. Public Health, 2015 Nov;46(6):1124-33.
PMID: 26867371

Illness and injury have a significant impact on employees, their families and employers. The consequences faced by an injured worker could lead to disability, which could then lead to inability to work. This study examined the patterns of the Return to Work (RTW) using data from The Social Security Organisation (SOCSO) of Malaysia RTW database from 2010 to 2013. Factors of successful return to work, employees' salary upon returning to formal employment were also investigated. Gender, age, year of injury, industry, and job hierarchy were found to be significant predictors of employees' salary upon returning to work. Although there are other costs involved on the part of employers and employees, themselves, in the long term the financial returns that can be brought back by injured workers who have successfully returned to work combined with the qualitative benefits substantially outweighs the costs of RTW program.

Fulltext Virtual Planning, Control, and Machining for a Modular-Based Automated Factory Operation in an Augmented Reality Environment

Pai YS, Yap HJ, Md Dawal SZ, Ramesh S, Phoon SY

Sci Rep, 2016 06 07;6:27380.
PMID: 27271840 DOI: 10.1038/srep27380

This study presents a modular-based implementation of augmented reality to provide an immersive experience in learning or teaching the planning phase, control system, and machining parameters of a fully automated work cell. The architecture of the system consists of three code modules that can operate independently or combined to create a complete system that is able to guide engineers from the layout planning phase to the prototyping of the final product. The layout planning module determines the best possible arrangement in a layout for the placement of various machines, in this case a conveyor belt for transportation, a robot arm for pick-and-place operations, and a computer numerical control milling machine to generate the final prototype. The robotic arm module simulates the pick-and-place operation offline from the conveyor belt to a computer numerical control (CNC) machine utilising collision detection and inverse kinematics. Finally, the CNC module performs virtual machining based on the Uniform Space Decomposition method and axis aligned bounding box collision detection. The conducted case study revealed that given the situation, a semi-circle shaped arrangement is desirable, whereas the pick-and-place system and the final generated G-code produced the highest deviation of 3.83 mm and 5.8 mm respectively.

Ahmed AA, Pradhan B

Environ Monit Assess, 2019 Feb 26;191(3):190.
PMID: 30809746 DOI: 10.1007/s10661-019-7333-3

This study proposes a neural network (NN) model to predict and simulate the propagation of vehicular traffic noise in a dense residential area at the New Klang Valley Expressway (NKVE) in Shah Alam, Malaysia. The proposed model comprises of two main simulation steps: that is, the prediction of vehicular traffic noise using NN and the simulation of the propagation of traffic noise emission using a mathematical model. First, the NN model was developed with the following selected noise predictors: the number of motorbikes, the sum of vehicles, car ratio, heavy vehicle ratio (e.g. truck, lorry and bus), highway density and a light detection and ranging (LiDAR)-derived digital surface model (DSM). Subsequently, NN and its hyperparameters were optimised by a systematic optimisation procedure based on a grid search approach. The noise propagation model was then developed in a geographic information system (GIS) using five variables, namely road geometry, barriers, distance, interaction of air particles and weather parameters. The noise measurement was conducted continuously at 15-min intervals and the data were analysed by taking the minimum, maximum and average values recorded during the day. The measurement was performed four times a day (i.e. morning, afternoon, evening, and midnight) over two days of the week (i.e. Sunday and Monday). An optimal radial basis function NN was used with 17 hidden layers. The learning rate and momentum values were 0.05 and 0.9, respectively. Finally, the accuracy of the proposed method achieved 78.4% with less than 4.02 dB (A) error in noise prediction. Overall, the proposed models were found to be promising tools for traffic noise assessment in dense urban areas.

Fulltext Validation of the dose distributions with Monte Carlo simulation for carbon ion cancer therapy

Ying, C.K., W.A. Kamil, Matsufuji, Naruhiro

Journal of Biomedical and Clinical Sciences, 2017;2(2):1-7.
MyJurnal

Charged particle therapy with carbon ions has advantages over conventional radiotherapy using x-ray beams. The application of charged particle therapy has rapidly increased over the last decades. This is due to its characteristic Bragg peak which has relatively low entrance doses and favourable doses distribution. In this research work, Geant4 based Monte Carlo simulation (MC) method has been used to calculate the radiation transportation and dose distributions in tissue-like media. The main objective of the work was to compare the Geant4 simulated depth dose distributions with experimental measurements and verify the capability of the geant4 simulation toolkit. The carbon ion beams for the therapeutic energy of 350 MeV/u and 400 MeV/u respectively were simulated, with the same settings as the experimental work carried out at the treatment room at Heavy Ion Medical Accelerator (HIMAC), National Institute of Radiological Sciences (NIRS), Chiba, Japan. The simulation results were verified with measurements data. The work was to measure the accuracy and quality of the dose distributions by Geant4 MC methods. The results show that the Bragg peak and spread out Bragg peak (SOBP) distributions in simulation has fairly good agreement with measurements.

Fulltext Using simulation model as a tool for analyzing bus service reliability and implementing improvement strategies

Moosavi SMH, Ismail A, Yuen CW

PLoS One, 2020;15(5):e0232799.
PMID: 32379848 DOI: 10.1371/journal.pone.0232799

Bus services naturally tend to be unstable and are not always capable of adhering to schedules without control strategies. Therefore, bus users and bus service providers face travel time variation and irregularity. After a comprehensive review of the literature, a significant gap was recognized in the field of public transportation reliability. According to literature, there is no consistency in reliability definition and indicators. Companies have their own definition of bus service reliability, and they mostly neglect the passengers' perspective of reliability. Therefore, four reliability indicators were selected in this study to fill the gap in the literature and cover both passengers' and operators' perceptions of reliability: waiting time and on-board crowding level from passengers' perspective, and headway regularity index at stops (HRIS) and bus bunching/big gap percentage from operators' perspective. The primary objective of this research is to improve the reliability of high frequency of bus service and simulation tools currently being used by the public transportation companies. Therefore, a simulation model of bus service was developed to study the strategies to alleviate it. Four different types of strategies were selected and implemented according to Route U32 (Kuala Lumpur) specifications. Model out-put showed that control strategies such as headway-based dispatching could significantly improve headway regularity by almost 62% and the waiting time by 51% on average. Both holding strategies at key stops (previous and Prefol holding) have shown an almost similar impact on reliability indicators. Waiting time was reduced by 44% and 43% after the previous and Prefol Headway strategies were adopted, respectively. However, the implementation of the component of headway-based strategies at the terminal and key stops showed the best impact on reliability, in terms of passenger waiting time. Waiting time and excess waiting time were both significantly reduced by 52.86% and 81.44%, respectively. Nevertheless, the strategies did not show any significant positive effect on the level of crowding during morning peak hours.

Turning Intentions into Animal Welfare Improvement in the Asian Livestock Sector

Sinclair M, Morton J, Phillips CJC

J Appl Anim Welf Sci, 2018 10 26;22(4):385-399.
PMID: 30362369 DOI: 10.1080/10888705.2018.1534590

Intentions form the basis of behavioral action to improve animal welfare; however an intention-behavior gap has been previously identified. Livestock stakeholders in China, Malaysia, Vietnam and Thailand (n = 1041) involved in slaughter and transport completed a survey in which they were asked their level of intention to improve animal welfare, and their level of confidence in their ability to do this. Chinese respondents had the most confidence in their ability to improve animal welfare, and veterinarians showed more confidence than livestock team leaders. Those with high or low intentions, and either high or low confidences were compared for key influencing factors to identify the circumstances that may be most conducive to behavior change. Respondents with high intentions and low confidence in their ability to improve animal welfare identified extrinsic factors associated with their immediate workplace and different company priorities, and the intrinsic factor of lack of personal knowledge. It is concluded that targeting these areas to improve confidence in stakeholders in livestock transport and slaughter could bring the most improvements in animal welfare initiatives.

Travel itinerary uncertainty and the pre-travel consultation--a pilot study

Flaherty G, Md Nor MN

J Travel Med, 2016 Jan;23(1).
PMID: 26782127 DOI: 10.1093/jtm/tav010

Risk assessment relies on the accuracy of the information provided by the traveller. A questionnaire was administered to 83 consecutive travellers attending a travel medicine clinic. The majority of travellers was uncertain about destinations within countries, transportation or type of accommodation. Most travellers were uncertain if they would be visiting malaria regions. The degree of uncertainty about itinerary potentially impacts on the ability of the travel medicine specialist to perform an adequate risk assessment, select appropriate vaccinations and prescribe malaria prophylaxis. This study reveals high levels of traveller uncertainty about their itinerary which may potentially reduce the effectiveness of their pre-travel consultation.

Fulltext Transport, Mobility and the Wellbeing of Older Adults: An Exploration of Private Chauffeuring and Companionship Services in Malaysia

Abdul Latiff AR, Mohd S

Int J Environ Res Public Health, 2023 Feb 03;20(3).
PMID: 36768086 DOI: 10.3390/ijerph20032720

As physical abilities and health decline with age, older adults tend to lose their driving abilities, which affects their mobility. As mobility is important to older adults' wellbeing, there is a need to explore alternative modes of transportation to increase their ability to actively participate in society. Hence, this paper aims to understand the characteristics of private chauffeuring and companionship services for older adults, and to assess their possible effects on older adults' wellbeing. We gathered the views of transport operators, government agencies, and city councils that offer private chauffeuring and companionship services for older adults. We frame the model of private chauffeuring and companionship services as alternative mobility for older adults and outline a conceptual framework for its possible effects on their wellbeing. The underlying mobility characteristics were availability, accessibility, safety, and affordability-all of which influence wellbeing. The study found that the private chauffeuring and companionship model for older adults includes an additional model of government-to-consumer services in addition to the existing peer-to-peer and business-to-consumer services. While the services are available, the services provided are not standardized, with different operators offering different services and prices, and limiting certain geographical areas. Transport operators perceived that the services they offer promote older adults' physical and mental health, improve their social participation in the community, and empower them in making their travel decisions. The findings of the paper provide insights for policy makers for future planning of alternative transportation for older adults to enhance their mobility.

Preventive tests and diagnosis of in-service power transformer are important for early fault prediction and increased reliability of electricity supply. However, some existing diagnostic techniques require transformer outage before the measurement can be performed and need expert knowledge and experiences to interpret the measurement results. Other measurement techniques such as chemical analyses of insulating oil may cause significant variance to measurement results due to different practices in oil sampling, storage, handling and transportation of oil. A cost-effective measuring technique, which is simple, providing fast and an accurate measurement results, is therefore highly required. The extended application of Polarisation and Depolarisation (PDC) measurement for characterisation of different faults conditions in-service power transformer has been presented in this paper. Earlier studies on polarisation and depolarisation current of oil samples from in-service power transformer shows that depolarisation has provided significant information about the change of material properties due to faults in power transformer. In this paper, a new approach based on Depolarisation Current Ratio Index (DRI) was developed for identifying and classifying different transformer fault conditions. The DRI at time interval of 4s to 100s was analysed and the results show that DRI of depolarisation current between 5/100s and 10/100s provides higher correlation on the incipient faults in power transformer.

Towards sets of hazardous waste indicators. Essential tools for modern industrial management

Peterson PJ, Granados A

Environ Sci Pollut Res Int, 2002;9(3):204-14.
PMID: 12094535

Decision-makers require useful tools, such as indicators, to help them make environmentally sound decisions leading to effective management of hazardous wastes. Four hazardous waste indicators are being tested for such a purpose by several countries within the Sustainable Development Indicator Programme of the United Nations Commission for Sustainable Development. However, these indicators only address the 'down-stream' end-of-pipe industrial situation. More creative thinking is clearly needed to develop a wider range of indicators that not only reflects all aspects of industrial production that generates hazardous waste but considers socio-economic implications of the waste as well. Sets of useful and innovative indicators are proposed that could be applied to the emerging paradigm shift away from conventional end-of-pipe management actions and towards preventive strategies that are being increasingly adopted by industry often in association with local and national governments. A methodological and conceptual framework for the development of a core-set of hazardous waste indicators has been developed. Some of the indicator sets outlined quantify preventive waste management strategies (including indicators for cleaner production, hazardous waste reduction/minimization and life cycle analysis), whilst other sets address proactive strategies (including changes in production and consumption patterns, eco-efficiency, eco-intensity and resource productivity). Indicators for quantifying transport of hazardous wastes are also described. It was concluded that a number of the indicators proposed could now be usefully implemented as management tools using existing industrial and economic data. As cleaner production technologies and waste minimization approaches are more widely deployed, and industry integrates environmental concerns at all levels of decision-making, it is expected that the necessary data for construction of the remaining indicators will soon become available.

The Healthy City concept was taken by Malaysia in 1994 and Malacca State has initiated this project in late 1997 and launched in September 1998. The aim of the project is to had ways of achieving a better quality of urban life. The objective of this study was to assess the views and responses of Melaka Tengah community with regards to the existing facilities and services rendered in the district. The views will be incorporated into ideas for the policymakers and planners to develop Malacca into a healthy city. Three methods were used to collect the data. Questionnaires were given to the community of Melaka Tengah District. The respondents were selected by multistage sampling, Observation was carried out at selected public places to assess the community's practices and contribution, Ten focus group discussion were conducted consisting of health staff and public to discuss on environmental, social, physical and economic issues of Malacca. There were 3 sectors that had mean scores above 3.0 (the cut off level for being satisfed). They were health, housing and environment, ln terms of dissatisfaction, there were 4 sectors scoring below 3.0, These include domestic waste dnposal, road system, public transportation and recreational park. The community
expected the services to be improved especially in terms of cleanliness, They agreed to contribute in their own ways in developing the sectors discussed except for public transportation, wet market and food premises which were beyond their control. Observation showed that some of the community members exhibit bad behaviours that can contribute to an unhealthy city. The Melaka
Tengah community expected ejficient and quality services and they agreed to contribute in making Malacca into a Healthy City.

Stress has been recognized one of the factors causing disease. About 70-80% of all diseases may be stress related. Thus, stress management can be a part of an early measure of disease prevention. A descriptive cross sectional, randomized study was conducted to determine the stress inducing factors among preclinical students (universal sampling) in a public university in Selangor, Malaysia from 24th April to May 2005. A total of 163 students (52.8% year 1, 36.8% year 2 and 10.4% year 3) were interviewed in the data collection process. The main reasons students entered - medical school was because of their own interest or ambition (65%) and family influence (20.9%). Majority (76.4%) suffered moderate to great stress over hot conditions in lecture hall, tutoriaV small group session rooms and laboratories while 53.4% suffered when using the other facilities like cafeteria, toilet and transportation:. Almost all (95.1%) felt that examination was the most stressful, followed by early clinical exposure sessions (68.1%), problem·based learning sessions (62.5%), hospital visitations (59.7%), tutoriay small group sessions (49.3%), practical class (44.5%) and attending lectures (3 8.5%). Musculoskeletal System was the most stressful module among the first year students, followed by Nervous System and Gastrointestinal System with the percentage of 94.2%, 90.7% and 88.4% respectively while, 95% of the second year students felt that General, Hemopoietic ci? Lymphoid and Nervous System are the most stressful modules. This study revealed that academic sessions and lack of conducive teaching and learning environment as the main stress inducing contributors to preclinical medical students.

The sources of the Kuznets relationship between the road deaths to road injuries ratio and economic growth

Sirajudeen AO, Law TH, Wong SV, Jakarni FM, Ng CP

J Safety Res, 2021 09;78:262-269.
PMID: 34399922 DOI: 10.1016/j.jsr.2021.06.007

INTRODUCTION: Past empirical studies indicated that there is a Kuznets or reverse U-shaped relationship between road deaths and per capita income, such that the number of road death increases at a low level of per capita reverse U-shaped relationship was observed between road injuries and per capita income. While these studies explored the impact of per capita income on road deaths and road injuries, no studies have examined the relationship between per capita income and road death to road injury ratio (DPI).
METHOD: Using a fixed effects panel regression analysis from 67 countries spanning over a period of five decades (1960-2013), the present study sought to explore the impact of per capita gross domestic product (per capita GDP) on the DPI ratio and the underlying factors responsible for the relationship.
RESULTS: Our result suggests that per capita GDP followed a reverse U-shaped relationship with DPI. Moreover, the relative improvements in higher mobility roads as compared to improvements in higher accessibility roads, motorcycle ownership to passenger car ownership ratio, percentage of population living in an urban area, infant mortality rate, and the percentage of population below 15 years of age and above 64 years of age contributed to this relationship. Practical Applications: This implies that, at lower level of economic growth where road deaths exceed road injuries, countries should implement low-cost measures to combat road deaths cases. Such measures include mandating wearing of quality helmets and daytime running headlights for motorcycles. On the other hand, at higher level of economic growth where road injuries surpass road deaths, countries are encouraged to devote more resources to improving medical technology and services to treat road injury victims, mandating seatbelt use, as well as enhancing and promoting public transportation service.

Fulltext The influence of spouses and their driving roles in self-regulation: A qualitative exploration of driving reduction and cessation practices amongst married older adults

Ang BH, Oxley JA, Chen WS, Yap MKK, Song KP, Lee SWH

PLoS One, 2020;15(5):e0232795.
PMID: 32413053 DOI: 10.1371/journal.pone.0232795

INTRODUCTION: There is growing evidence to suggest the importance of self-regulatory practices amongst older adults to sustain mobility. However, the decision to self-regulate driving is a complex interplay between an individual's preference and the influence of their social networks including spouse. To our best knowledge, the influence of an older adult's spouse on their decisions during driving transition has not been explored.
MATERIALS AND METHODS: This qualitative descriptive study was conducted amongst married older adults aged 60 years and above. All interview responses were transcribed verbatim and examined using thematic approach and interpretative description method.
RESULTS: A total of 11 married couples were interviewed. Three major themes emerged: [1] Our roles in driving; [2] Challenges to continue driving; and, [3] Our driving strategies to ensure continued driving. Older couples adopted driving strategies and regulated their driving patterns to ensure they continued to drive safely. Male partners often took the active driving role as the principal drivers, while the females adopted a more passive role, including being the passenger to accompany the principal drivers or becoming the co-driver to help in navigation. Other coping strategies include sharing the driving duties as well as using public transportation or mixed mode transportation.
DISCUSSION: Our findings suggest spouse play a significant role in their partners' decision to self-regulate driving. This underscores a need to recognise the importance of interdependency amongst couples and its impact on their driving decisions and outcomes.

PMID: 24574875 DOI: 10.1155/2014/240786

The main objective of this paper is to investigate the relations of rubber size, rubber content, and binder content in determination of optimum binder content for open graded friction course (OGFC). Mix gradation type B as specified in Specification for Porous Asphalt produced by the Road Engineering Association of Malaysia (REAM) was used in this study. Marshall specimens were prepared with four different sizes of rubber, namely, 20 mesh size [0.841 mm], 40 mesh [0.42 mm], 80 mesh [0.177 mm], and 100 mesh [0.149 mm] with different concentrations of rubberised bitumen (4%, 8%, and 12%) and different percentages of binder content (4%-7%). The appropriate optimum binder content is then selected according to the results of the air voids, binder draindown, and abrasion loss test. Test results found that crumb rubber particle size can affect the optimum binder content for OGFC.

The asymmetric role of freight and passenger transportation in testing EKC in the US economy: evidence from QARDL approach

Godil DI, Sharif A, Afshan S, Yousuf A, Khan SAR

Environ Sci Pollut Res Int, 2020 Aug;27(24):30108-30117.
PMID: 32447733 DOI: 10.1007/s11356-020-09299-7

This study examines the association between transportation services (i.e., passenger and freight) and carbon emissions concerning the US economy. The monthly data for this study were collected for the period from 2000 M1 to 2019 M8. In this study, QARDL econometric approach as discussed by Cho et al. (2015) has been used to tests the relationship between transportation services and CO2 emissions. Due to the chaotic and nonlinear behavior of our concerning variables, it was quite difficult to gauge the principle properties of their variations. Therefore, we relied on QARDL, which has been missing in previous researches. By utilizing the QARDL method, this research assesses the long-term stability of the nexus across the quantiles to provide an econometric framework that is more flexible than the traditional ones. In particular, the authors have analyzed how the quantiles of transportation (i.e., passenger and freight) influence the quantiles of CO2 emissions (environmental degradation). The empirical evidence revealed the negative significant relationship of both the transportation system (i.e., passenger and freight) with carbon emissions; however, this relationship holds at low quantiles of freight transport, whereas the same relationship has been observed at the majority of quantiles of passenger transport. So, this depicts that the transportation system of the USA helps to reduce CO2 emissions. Therefore, to maintain this situation, the government shall introduce more technologies that are fuel-efficient and promote clean consumption, thus reducing CO2 emissions, boosting economic growth, and making green transportation services.

The ameliorative effect of ascorbic acid on the oxidative status, live weight and recovery rate in road transport stressed goats in a hot humid tropical environment

Nwunuji TP, Mayowa OO, Yusoff SM, Bejo SK, Salisi S, Mohd EA

Anim Sci J, 2014 May;85(5):611-6.
PMID: 24612236 DOI: 10.1111/asj.12174

The ameliorative effect of ascorbic acid (AA) on live weight following transportation is vital in animal husbandry. This study investigated the influence of AA on live weight, rectal temperature (rt), and oxidative status of transport stressed goats in a hot humid tropical environment. Twenty-four goats were divided into four groups, A, B, C and D of six animals each. Group A were administered AA 100 mg/kg intramuscularly 30 min prior to 3.5 h transportation. Group B was administered AA following transportation. Group C were transported but not administered AA as positive controls while group D were not transported but were administered normal saline as negative controls. Live weight, rt and blood samples were collected before, immediately post-transport (pt), 24 h, 3 days, 7 days and 10 days pt. Plasma was used for malondialdehyde (MDA) analysis while hemolysates were used for superoxide dismutase (SOD) analysis. There was minimal live weight loss in group A compared to groups B and C. Group A recorded reduced MDA activities and increased SOD activities compared to groups B and C which recorded significantly high MDA activities. This study revealed that AA administration ameliorated the stress responses induced by transportation in animals in hot humid tropical environments. The administration of AA to goats prior to transportation could ameliorate stress and enhance productivity.
