    Preventive maintenance (PM) planning becomes a crucial issue in the real world of the manufacturing process. It is important in the manufacturing industry to maintain the optimum level of production and minimize its investments. Thus, this paper focuses on multiple jobs with a single production line by considering stochastic machine breakdown time. The aim of this paper is to propose a good integration of production and PM schedule that will minimize total completion time. In this study, a hybrid method, which is a genetic algorithm (GA), is used with the Monte Carlo simulation (MCS) technique to deal with the uncertain behavior of machine breakdown time. A deterministic model is adopted and tested under different levels of complexity. Its performance is evaluated based on the value of average completion time. The result clearly shows that the proposed integrated production with PM schedule can reduce the average completion time by 11.68% compared to the production scheduling with machine breakdown time.

    Agents are the most important marketing tools for company to become a successful in business. Agents not only operate as a channel to customers, but they also play an important role in providing customers with a variety of services before and after the sales. The main purpose of this study is to identify the factor influencing agent’s sales at an Apparel Manufacturing company. There are three categories of agents at the company namely, Trial agent, Basic agent and Premium agent. Based on the sales records in May 2018, the sales of product obtained by Trial Agent is lower than Basic and Premium Agents in this company. Therefore, this study aims to determine difference mean on record sales by agent among three categories of agents. This study also investigates the relationship between sales records by agents and years of experienced in business. Data was collected using questionnaire from 46 active agents at the company. Data was analyzed using One-way Analysis of Variance (ANOVA), Pearson correlation coefficient and Multiple Linear Regression. Result showed that there is a statistically significant difference in the mean sales records among the three of agent’s categories. Furthermore, there is a strong positive correlation between sales records by agent and years of experienced in business. Meanwhile, factors of knowledge and skills in business are most contributed to the agent’s sales. This study can help the company to create a strategic business plan and conducting several workshop trainings for agents to increase their knowledge and skills in business.

  3. Is the food environment surrounding schools associated with the diet quality of adolescents in Otago, New Zealand?
    Clark EM, Quigg R, Wong JE, Richards R, Black KE, Skidmore PM
    Health Place, 2014 Nov;30:78-85.
    PMID: 25218636 DOI: 10.1016/j.healthplace.2014.08.008
    Using a sample of adolescents from schools in Otago, New Zealand, associations between food outlets around schools and dietary quality were investigated. Food outlet environment data were derived using GIS data. Multivariate regression analysis results showed that outlet density, in an 800m buffer around schools, of cafes and restaurants, supermarkets and takeaways was associated with higher Diet Quality Index scores in boys, and distance to nearest outlet for convenience stores, cafes and restaurants and supermarkets with lower scores for girls. Effect sizes were small, suggesting that the food environment around schools plays a minor role in adolescent diet quality.

  4. Fulltext The empirical analysis of cigarette tax avoidance and illicit trade in Vietnam, 1998-2010
    Nguyen MT, Denniston R, Nguyen HT, Hoang TA, Ross H, So AD
    PLoS One, 2014;9(1):e87272.
    PMID: 24489886 DOI: 10.1371/journal.pone.0087272
    Illicit trade carries the potential to magnify existing tobacco-related health care costs through increased availability of untaxed and inexpensive cigarettes. What is known with respect to the magnitude of illicit trade for Vietnam is produced primarily by the industry, and methodologies are typically opaque. Independent assessment of the illicit cigarette trade in Vietnam is vital to tobacco control policy. This paper measures the magnitude of illicit cigarette trade for Vietnam between 1998 and 2010 using two methods, discrepancies between legitimate domestic cigarette sales and domestic tobacco consumption estimated from surveys, and trade discrepancies as recorded by Vietnam and trade partners. The results indicate that Vietnam likely experienced net smuggling in during the period studied. With the inclusion of adjustments for survey respondent under-reporting, inward illicit trade likely occurred in three of the four years for which surveys were available. Discrepancies in trade records indicate that the value of smuggled cigarettes into Vietnam ranges from $100 million to $300 million between 2000 and 2010 and that these cigarettes primarily originate in Singapore, Hong Kong, Macao, Malaysia, and Australia. Notable differences in trends over time exist between the two methods, but by comparison, the industry estimates consistently place the magnitude of illicit trade at the upper bounds of what this study shows. The unavailability of annual, survey-based estimates of consumption may obscure the true, annual trend over time. Second, as surveys changed over time, estimates relying on them may be inconsistent with one another. Finally, these two methods measure different components of illicit trade, specifically consumption of illicit cigarettes regardless of origin and smuggling of cigarettes into a particular market. However, absent a gold standard, comparisons of different approaches to illicit trade measurement serve efforts to refine and improve measurement approaches and estimates.

  5. Listeria monocytogenes in retailed raw chicken meat in Malaysia
    Goh SG, Kuan CH, Loo YY, Chang WS, Lye YL, Soopna P, et al.
    Poult Sci, 2012 Oct;91(10):2686-90.
    PMID: 22991558
    This study aimed to determine the prevalence Listeria monocytogenes in raw chicken meat samples at hypermarkets and wet markets. Chicken drumsticks, breasts, and thighs were randomly selected. The most probable number (MPN) PCR method was used to quantify the L. monocytogenes in the samples. Listeria monocytogenes was detected in 20% of the samples. Occurrence of L. monocytogenes was highest in breast (42.03%) followed by drumstick (11.27%) and thigh (7.14%). Samples from hypermarkets showed higher occurrence (25.71%) of L. monocytogenes compared with wet markets (14.29%). The density of L. monocytogenes found in samples ranged from <3.0 to 16 MPN•g(-1). The presence of L. monocytogenes in raw chicken meat is unwanted but unpreventable. Thus, further research on the processing method to reduce and eliminate this kind of bacteria in chicken meat before consumption is necessary. The presence of L. monocytogenes in chicken samples suggests the importance of this pathogen in chicken. Thus, more study is needed to find ways to eliminate this pathogen from poultry.

    Shroff SM, Sreeramareddy CT
    Subst Abuse Treat Prev Policy, 2024 Jan 25;19(1):11.
    PMID: 38273314 DOI: 10.1186/s13011-024-00592-z
    BACKGROUND: Marketing and sales of e-cigarettes are unregulated in Malaysia. We analyzed content displayed on e-cigarette retailer websites to identify marketing claims, promotional strategies, and product details in the year 2022.

    METHODS: We analyzed 30 Malaysia-based retailer websites using a mixed methods approach. Data were extracted as the frequency of occurrences of marketing claims, presence of regulatory information, product types, and flavors of e-juice as per a predefined codebook based on published literature. We also extracted textual details published on the websites about marketing claims, and slogans.

    RESULTS: Most retailer websites provided contact information and physical store addresses (83%) but only half had 'click through' age verification (57%) that seldom needed any identification proof for age (3%). Marketing claims were related to health (47%), smoking cessation (37%), and modernity/trend (37%) and none had health warnings. Promotional strategies were discounts (80%). starter kits (57%) and email subscriptions (53%). Product types displayed were rechargeable (97%) and disposable (87%) devices and e-liquids (90%) of an array of flavors (> 100). Nicotine presence, its concentration, and "nicotine is an addictive chemical" were displayed in 93%, 53%, and 23% of websites respectively.

    CONCLUSION: Surveillance of content displayed online on e-cigarette retailer websites and regulation of online marketing and sales should be implemented by the Ministry of Health, Malaysia. Such measures are needed to prevent access to, and initiation of e-cigarette use among the youth and adults who do not smoke.

  8. TPPA and tobacco control: threats to APEC countries
    Sy DK, Stumberg RK
    Tob Control, 2014 Nov;23(6):466-70.
    PMID: 25170023 DOI: 10.1136/tobaccocontrol-2014-051900
    Twelve-member countries of the Asia Pacific Economic Cooperation (APEC) are negotiating the Trans-Pacific Partnership Agreement (TPPA), a free trade agreement to facilitate international trade and investment. As reported by multiple sources, the TPPA would grant the same trade benefits and legal protections to tobacco products, services and investments that it would provide to other sectors. Malaysia proposed excluding tobacco control measures from the scope of all TPPA chapters while the US proposed only to establish a consultation process in tobacco-related disputes and to declare that tobacco control measures serve a health objective within the scope of the general exceptions.

  9. ENTEROAGGREGATIVE ESCHERICHIA COLI O104 FROM THAI AND IMPORTED MALAYSIAN RAW BEEF
    Wameadesa N, Sae-lim A, Hayeebilan F, Rattanachuay P, Sukhumungoon P
    Southeast Asian J. Trop. Med. Public Health, 2017 Mar;48(2):338-50.
    PMID: 29642296
    Local Thai and imported Malaysian beef in southern Thailand area carry
    several Shiga toxin-producing Escherichia coli (STEC) serotypes. STEC O104 is an
    important pathogen capable of causing outbreaks with considerable morbidity
    and mortality. This study investigated the presence of E. coli O104 from local Thai
    and imported Malaysian beef obtained from markets in Hat Yai City, Songkhla
    Province during August 2015 - February 2016. Thirty-one E. coli O104 strains
    were isolated from 12 beef samples (16% and 23% Thai and imported Malaysian,
    respectively). Thirty strains possessed aggA (coding for a major component of
    AAF/I fimbriae), a gene associated with enteroaggregative E. coli (EAEC) pathotype,
    and all strains carried fimH (encoding Type 1 fimbriae). Thirty strains
    belonged to phylogenetic group B1 and one strain (from Malaysian beef) to group
    A. Agglutination of yeast cells was observed among 29 E. coli O104 strains. Investigation
    of stx2 phage occupancy loci demonstrated that sbcB was occupied in 12
    strains. Antimicrobial susceptibility assay revealed that 7 strains were resistant
    to at least one antimicrobial agent and two were multi-drug resistant. One strain
    carried extended spectrum β-lactamase gene blaCTX-M and three carried blaTEM. PFGE-generated DNA profiling showed identical DNA pattern between that of
    one EAEC O104 strain from Thai beef and another from Malaysian beef, indicating
    that these two strains originated from the same clone. This is the first report
    in Thailand describing the presence of EAEC O104 from both Thai and imported
    Malaysian beef and their transfer between both countries. Thorough surveillance
    of this pathogen in fresh meats and vegetables should help to prevent any possible
    outbreak of E. coli O104.

  10. Integrated models for shipping a vendor’s final production batch to a single buyer under linearly decreasing demand for consignment policy
    Omar M, Supadi S
    Sains Malaysiana, 2012;41:367-370.
    This paper considers the problem of a vendor or manufacturer supplying a final production batch to a single buyer under linearly decreasing demand for a finite time horizon. The vendor manufactures the product at a finite rate and ships the output to the buyer. In this model we considered the case where the holding cost at the vendor is greater than the buyer and propose a consignment model. The objective was to minimize the total cost of stock transfer from vendor to buyer and stock holding at the vendor and the buyer. We derived the structure of the optimal solution and illustrate the proposed models with numerical examples.

  11. Fulltext The impact of service quality on business commitment in B2B segment of agribusiness: An exploratory study of HORECA sector in Malaysia
    Tey, Y.S., Brindal, M., Fatimah, M.A., Kusairi, M.N., Ahmad Hanis, I.A.H., Suryani, D.

    In competitive markets, agribusiness firms have embarked on improving their service quality for building and maintaining a profitable relationship with their customers. However, such impact of service quality on business commitment has not been empirically investigated. To fill this gap, this study explores the relationship between service quality and commitment, using a case of supplier selection of fresh produce by hotel, restaurant, and catering (HORECA) sector in Malaysia. Using SERVQUAL as the main component of the conceptual framework, the relevant information was collected from 195 random HORECA operators and analyzed using partial least squares. The results indicate that service quality explains little of HORECA’s decision to stay with their current suppliers. While most service quality factors were insignificant, “responsiveness” in term of providing delivery service had a statistically significant positive impact on HORECA’s contractual arrangement with their current suppliers. These findings imply that quality service is being seen as a supplement; economic factors (e.g., prices and their stability, credit term) are likely to be the key drivers affecting buyer-seller relationships. If suppliers want to stay on course, they have to improve their service quality and focus more on delivery service. In addition, more research is needed in this relatively new area.

  12. Fulltext A collective call to strengthen monitoring and evaluation efforts to support healthy and sustainable food systems: 'The Accountability Pact'
    Garton K, Kraak V, Fanzo J, Sacks G, Vandevijvere S, Haddad L, et al.
    Public Health Nutr, 2022 Sep;25(9):2353-2357.
    PMID: 35570707 DOI: 10.1017/S1368980022001173
    There is widespread agreement among experts that a fundamental reorientation of global, regional, national and local food systems is needed to achieve the UN Sustainable Development Goals Agenda and address the linked challenges of undernutrition, obesity and climate change described as the Global Syndemic. Recognising the urgency of this imperative, a wide range of global stakeholders - governments, civil society, academia, agri-food industry, business leaders and donors - convened at the September 2021 UN Food Systems Summit to coordinate numerous statements, commitments and declarations for action to transform food systems. As the dust settles, how will they be pieced together, how will governments and food corporations be held to account and by whom? New data, analytical methods and global coalitions have created an opportunity and a need for those working in food systems monitoring to scale up and connect their efforts in order to inform and strengthen accountability actions for food systems. To this end, we present - and encourage stakeholders to join or support - an Accountability Pact to catalyse an evidence-informed transformation of current food systems to promote human and ecological health and wellbeing, social equity and economic prosperity.

    Widespread use of mobile devices has resulted in the creation of large amounts of data. An example of such data is the one obtained from the public (crowd) through open calls, known as crowdsourced data. More often than not, the collected data are later used for other purposes such as making predictions. Thus, it is important for crowdsourced data to be recent and accurate, and this means that frequent updating is necessary. One of the challenges in using crowdsourced data is the unpredictable incoming data rate. Therefore, manually updating the data at predetermined intervals is not practical. In this paper, the construction of an algorithm that automatically updates crowdsourced data based on the rate of incoming data is presented. The objective is to ensure that up-to-date and correct crowdsourced data are stored in the database at any point in time so that the information available is updated and accurate; hence, it is reliable. The algorithm was evaluated using a prototype development of a local price-watch information application, CrowdGrocr, in which the algorithm was embedded. The results showed that the algorithm was able to ensure up-to-date information with 94.9% accuracy.

  14. Unraveling the driving factors of the plastic waste trade network formation and dynamics
    Liu F, Fan C, Li J, Tan Q
    J Environ Manage, 2023 Dec 15;348:119422.
    PMID: 37879176 DOI: 10.1016/j.jenvman.2023.119422
    International trade of plastic waste promotes the global plastic circular economy and improves resource efficiency, but exacerbates the ubiquitous plastic pollution. Understanding the drivers behind the evolution of the global plastic waste trade network (GPWTN) is pivotal for developing new international instruments to end plastic pollution and fostering clean solid-waste trade. Employing social network analysis (SNA) and quadratic assignment procedure (QAP) model, this study structures the GPWTN using bilateral trade data, revealing shifts from highly centralized to cross-layered networks and relevant drivers. It is suggested that Malaysia and Turkey has become the new key recipients of the GPWTN, replacing China, accompanied by the launch of new environmental regulations in some countries. Transportation cost is the most critical factor for the formation of the GPWTN, followed by gaps in resource demand, bio-based resource availability, and transportation accessibility. Trading partners in closer proximity, especially those with contiguous borders, are more likely to trade in waste plastics, while coastal countries play an important role in these partnerships. Economies with more abundant biomaterials, higher incomes, and greater environmental burdens are more likely to be exporters, while economies with scarcer resources and more compelling demands are more likely to import plastic waste. Countries involved in the trade in plastic waste, as either importers or exporters, receive varying degrees of economic benefits but bear potential environmental impacts. Therefore, global plastic pollution control and trade prosperity necessitates necessitate coordinated endeavors from nations and intergovernmental bodies for a mutually advantageous denouement.

  15. Fulltext Time series analysis of factors affecting the demand for local rice in Malaysia
    Chung, B. H., Tan, J. R.
    International Food Research Journal, 2015;22(5):1870-1877.
    MyJurnal
    The own price, income and price of a substitute are the determinants of demand in the classical theory of consumer behavior. We used the theory to analyze the demand for local rice in Malaysia by using time series variables. We examined whether there is a long run relationship among the variables by using the unit root and cointegration tests. We then conducted the Granger causality, variance decomposition and impulse response function tests to examine their directions of causality as well as short term dynamics. The results show that there is a long run relationship among the variables and a unidirectional causality from price and income to demand. There are also lagged and short term dynamics among the variables.

  16. Fulltext Artificial dragonfly algorithm in the Hopfield neural network for optimal Exact Boolean k satisfiability representation
    Ali GA, Abubakar H, Alzaeemi SAS, Almawgani AHM, Sulaiman A, Tay KG
    PLoS One, 2023;18(9):e0286874.
    PMID: 37747876 DOI: 10.1371/journal.pone.0286874
    This study proposes a novel hybrid computational approach that integrates the artificial dragonfly algorithm (ADA) with the Hopfield neural network (HNN) to achieve an optimal representation of the Exact Boolean kSatisfiability (EBkSAT) logical rule. The primary objective is to investigate the effectiveness and robustness of the ADA algorithm in expediting the training phase of the HNN to attain an optimized EBkSAT logic representation. To assess the performance of the proposed hybrid computational model, a specific Exact Boolean kSatisfiability problem is constructed, and simulated data sets are generated. The evaluation metrics employed include the global minimum ratio (GmR), root mean square error (RMSE), mean absolute percentage error (MAPE), and network computational time (CT) for EBkSAT representation. Comparative analyses are conducted between the results obtained from the proposed model and existing models in the literature. The findings demonstrate that the proposed hybrid model, ADA-HNN-EBkSAT, surpasses existing models in terms of accuracy and computational time. This suggests that the ADA algorithm exhibits effective compatibility with the HNN for achieving an optimal representation of the EBkSAT logical rule. These outcomes carry significant implications for addressing intricate optimization problems across diverse domains, including computer science, engineering, and business.

  17. Complex multiple introductions drive fall armyworm invasions into Asia and Australia
    Rane R, Walsh TK, Lenancker P, Gock A, Dao TH, Nguyen VL, et al.
    Sci Rep, 2023 Jan 12;13(1):660.
    PMID: 36635481 DOI: 10.1038/s41598-023-27501-x
    The fall armyworm (FAW) Spodoptera frugiperda is thought to have undergone a rapid 'west-to-east' spread since 2016 when it was first identified in western Africa. Between 2018 and 2020, it was recorded from South Asia (SA), Southeast Asia (SEA), East Asia (EA), and Pacific/Australia (PA). Population genomic analyses enabled the understanding of pathways, population sources, and gene flow in this notorious agricultural pest species. Using neutral single nucleotide polymorphic (SNP) DNA markers, we detected genome introgression that suggested most populations in this study were overwhelmingly C- and R-strain hybrids (n = 252/262). SNP and mitochondrial DNA markers identified multiple introductions that were most parsimoniously explained by anthropogenic-assisted spread, i.e., associated with international trade of live/fresh plants and plant products, and involved 'bridgehead populations' in countries to enable successful pest establishment in neighbouring countries. Distinct population genomic signatures between Myanmar and China do not support the 'African origin spread' nor the 'Myanmar source population to China' hypotheses. Significant genetic differentiation between populations from different Australian states supported multiple pathways involving distinct SEA populations. Our study identified Asia as a biosecurity hotspot and a FAW genetic melting pot, and demonstrated the use of genome analysis to disentangle preventable human-assisted pest introductions from unpreventable natural pest spread.

  18. Fulltext Analysis of the key influencing factors of China's cross-border e-commerce ecosystem based on the DEMATEL-ISM method
    Xi X, Wei M, Teo BS
    PLoS One, 2023;18(8):e0287401.
    PMID: 37561794 DOI: 10.1371/journal.pone.0287401
    Systematically analysing the relative importance and hierarchical relationships among the influencing factors of the cross-border e-commerce ecosystem holds rich theoretical value and practical significance for the development of this ecosystem. A total of 19 influencing factors covering four aspects affecting the cross-border e-commerce ecosystem are identified by means of the relevant literature, web pages, research, and discussions with relevant experts and scholars, and the decision-making trial and evaluation laboratory (DEMATEL) and interpretative structural modeling (ISM) method is used to analyse the cause-effect correlation of each factor and to obtain a cause-effect diagram and a multi-level recursive structure model. The results show that three factors, i.e., the e-commerce platform development level, cross-border e-commerce competitiveness, and the cross-border e-commerce transaction scale, have a greater degree of influence on the other influencing factors. Additionally, three factors, i.e., the information development level, GDP, and cross-border online shopping demand, are vulnerable to the influence of the other factors. The level of cross-border e-commerce platform development, cross-border e-commerce competitiveness, and inter-firm competition are the root factors and occupy an important position in the cross-border e-commerce ecosystem as influencing factors and influence the stability of the cross-border e-commerce ecosystem by affecting the other factors.
