Selecting a suitable Multi Criteria Decision Making (MCDM) method is a crucial stage to establish a Solid Waste Management (SWM) system. Main objective of the current study is to demonstrate and evaluate a proposed method using Multiple Criteria Decision Making methods (MCDM). An improved version of Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) applied to obtain the best municipal solid waste management method by comparing and ranking the scenarios. Applying this method in order to rank treatment methods is introduced as one contribution of the study. Besides, Viekriterijumsko Kompromisno Rangiranje (VIKOR) compromise solution method applied for sensitivity analyses. The proposed method can assist urban decision makers in prioritizing and selecting an optimized Municipal Solid Waste (MSW) treatment system. Besides, a logical and systematic scientific method was proposed to guide an appropriate decision-making. A modified TOPSIS methodology as a superior to existing methods for first time was applied for MSW problems. Applying this method in order to rank treatment methods is introduced as one contribution of the study. Next, 11 scenarios of MSW treatment methods are defined and compared environmentally and economically based on the waste management conditions. Results show that integrating a sanitary landfill (18.1%), RDF (3.1%), composting (2%), anaerobic digestion (40.4%), and recycling (36.4%) was an optimized model of integrated waste management. An applied decision-making structure provides the opportunity for optimum decision-making. Therefore, the mix of recycling and anaerobic digestion and a sanitary landfill with Electricity Production (EP) are the preferred options for MSW management.

Fulltext Knowledge, Awareness, and Perception of Genetic Testing for Hereditary Disorders Among Malaysians in Klang Valley

Chin JJ, Tham HW

Front Genet, 2020;11:512582.
PMID: 33343613 DOI: 10.3389/fgene.2020.512582

Genetic testing aids patients in making important decisions in the prevention, treatment, or early detection of hereditary disorders. Low awareness of the importance of genetic testing contributes to the increase in the incidence of hereditary disorders. This study aims to explore the knowledge, awareness, and perception of genetic testing for hereditary disorders among local residents of the Klang Valley, Malaysia, and the potential variables that influence their understanding of genetic testing. A survey was conducted in different municipalities of the Klang Valley through self-administered questionnaire assessing the public's knowledge, awareness, and perception of genetic testing. Overall, the results revealed adequate knowledge and positive awareness of genetic testing, in which both were influenced by the respondent's educational level (P < 0.001), field of study (P < 0.001), and status of heard or unheard of genetic testing (P < 0.001). The perception of genetic testing was generally positive and influenced by the respondent's differences in age (P < 0.016), educational level (P < 0.001), field of study (P < 0.001), and status of heard or unheard of genetic testing (P < 0.001). Although positive responses were obtained, ~20.2% of the respondents had never heard of genetic testing. Of the respondents, 24.5% were unwilling to undergo genetic testing, with 25.1% believing that genetic testing tampers with nature and 18% believing that it opposes religion and their beliefs. Such attitude calls for the need to conduct programs to eliminate any misconception, as well as to educate the public to lessen any perceived misunderstanding of the concepts of genetic testing.

Chong ZX, Yeap SK, Ho WY

PeerJ, 2021;9:e11165.
PMID: 33976969 DOI: 10.7717/peerj.11165

Transfection is a modern and powerful method used to insert foreign nucleic acids into eukaryotic cells. The ability to modify host cells' genetic content enables the broad application of this process in studying normal cellular processes, disease molecular mechanism and gene therapeutic effect. In this review, we summarized and compared the findings from various reported literature on the characteristics, strengths, and limitations of various transfection methods, type of transfected nucleic acids, transfection controls and approaches to assess transfection efficiency. With the vast choices of approaches available, we hope that this review will help researchers, especially those new to the field, in their decision making over the transfection protocol or strategy appropriate for their experimental aims.

Fulltext Importance of economic evaluation in health care decision making

Aniza, I., Hossein, M., Otgonbayar, R., Munkhtuul, Y.

Malaysian Journal of Community Health, 2008;14(1):1-10.
MyJurnal

Introduction : Economic evaluations can provide “value-for money” information to those making decisions about the allocation of limited health care resources. In particular, economic evaluations can be used to identify interventions that are worth providing and those that are not. Furthermore, evaluations can be used with other approaches to help set priorities, such as program-budgeting marginal-analysis.
Methodology : Compile and systematically describe from the publications, articles and reports on economic evaluation in healthcare decision making.
Result : A high quality economic evaluation should provide decision makers with information that is useful, relevant, and timely. In addition, evaluations should be based on rigorous analytical methods, be balanced and impartial (credible), and be transparent and accessible to the reader. There are many situations where economic evaluations can assist decision makers: decisions by various levels of government or administrative bodies (e.g., regional health authorities, hospitals, drug plans) to fund a program, service or technology, pricing decisions by government regulators and technology manufacturers, clinical practice guidelines, priorities for research funding by governments and researchbased firms, post-marketing surveillance and updates of economic information based on the use of the technology in the “real world” (which can then be used to inform one of the other types of decisions).
Conclusion: This requires that decision makers take a broad view of the impact of a technology, and decision that are more explicit and transparent. The ultimate test of an evaluation is whether it leads to better decision in the presence of uncertainty, and results in the more efficient and effective use of resources.

Loh, Kok Fook, Ponusamy, Ragu, Shattri Mansor, Jamil Ismail

Pertanika Journal of Science & Technology, 2009;17(1):-.
MyJurnal

Malaysia is in the process of modernizing its oil palm plantation management, by implementing geo-information technologies which include Remote Sensing (RS), Geographic Information System (GIS), and Spatial Decision Support System (DSS). Agencies with large oil palm plantations such as the Federal Land Development Authority (FELDA), Federal Land Consolidation and Rehabilitation Authority (FELCRA), Guthrie Sdn. Bhd., and Golden Hope Sdn. Bhd. have already incorporated GIS in their plantation management, with limited use of RS and DSS. In 2005, FELCRA, Universiti Putra Malaysia (UPM) and Espatial Resources Sdn. Bhd. (ESR) collaborated in a research project to explore the potentials of geo-informatics for oil palm plantation management. The research was conducted in FELCRA located in Seberang Perak Oil Palm Scheme. In that research, a tool integrating RS, GIS and Analytical Hierarchy Process (AHP) was developed to support decision making for replanting of the existing old palms. RS was used to extract productive stand per hectare; AHP was used to compute the criteria weights for the development of a suitable model; and GIS was used for spatial modelling so as to generate the decision support layer for replanting. This paper highlights the approach adopted in developing the tool with special emphasis on the AHP computation.

Fulltext Models and theories of prescribing decisions: A review and suggested a new model

Murshid MA, Mohaidin Z

Pharm Pract (Granada), 2017 Apr-Jun;15(2):990.
PMID: 28690701 DOI: 10.18549/PharmPract.2017.02.990

To date, research on the prescribing decisions of physician lacks sound theoretical foundations. In fact, drug prescribing by doctors is a complex phenomenon influenced by various factors. Most of the existing studies in the area of drug prescription explain the process of decision-making by physicians via the exploratory approach rather than theoretical. Therefore, this review is an attempt to suggest a value conceptual model that explains the theoretical linkages existing between marketing efforts, patient and pharmacist and physician decision to prescribe the drugs. The paper follows an inclusive review approach and applies the previous theoretical models of prescribing behaviour to identify the relational factors. More specifically, the report identifies and uses several valuable perspectives such as the 'persuasion theory - elaboration likelihood model', the stimuli-response marketing model', the 'agency theory', the theory of planned behaviour,' and 'social power theory,' in developing an innovative conceptual paradigm. Based on the combination of existing methods and previous models, this paper suggests a new conceptual model of the physician decision-making process. This unique model has the potential for use in further research.

Norhaiza K, Rozainee K, Mohd Noor Abdul H, Phillip H, McGill T, Zainah Ahmad Z

Jurnal Psikologi Malaysia, 2016;30:102-113.

This research examined how managers in universities incorporate non-financial measures in their Learning Management Systems decision-making processes and particularly focused on the importance of the Human Capital perspective in LMS decision making processes. A mixed-methods approach to data collection was used involving both interviews and questionnaires. The qualitative data from the interviews were coded and analysed. A descriptive coding method using thematic analysis was used for the data coding. The qualitative data were analysed using an inductive approach where the categories of criteria and indicators were not determined before the interview. The participants in this research were five members of LMS decision-making teams at two different universities in Australia and 24 participants from different universities in Malaysia who were involved in LMS decision- making processes at their universities. The results of this research indicated that there was substantial support for using a multi-dimensional decision making model among IT decision makers at universities, particularly the Human Capital perspective and they believed that Human Capital measures are important and should be considered in a LMS decision making process.The research has both implications for theory and for practitioners where it contributes to the knowledge on LMS decision making in universities and IT decision making in general, and also in improving actual decision making practices.

Fulltext Decision making procedure based on Jaccard similarity measure with z-numbers

Mohamad, D., Ibrahim, S.Z.

Pertanika Journal of Science & Technology, 2017;25(2):561-574.
MyJurnal

Fuzzy set with similarity measure approaches are known to be effective in handling imprecise and
subjective information to solve decision making problems. Many methods have been introduced based on these two concepts. However, most methods do not take into account the reliability factor of the imprecise information in the evaluation process. In 2010, Zadeh coined the idea of Z-number that has the ability to consider the reliability factor or the level of confidence of human’s information expression. Since then, some decision-making methods have included this concept. In this paper, we present a new fuzzy decision making procedure by integrating the Jaccard similarity measure with Z-number to solve a multi criteria decision making problem. The conversion method of the Z-number based linguistic value to trapezoidal fuzzy numbers is used and the Jaccard similarity measure of the expected intervals of trapezoidal fuzzy numbers is applied to obtain the final decision. The feasibility of the methodology is demonstrated by investigating the preference factors that could influence customers to buy their preferred choice of car. The proposed methodology is applicable to solving decision making with a fuzzy environment to achieve a reliable and optimal decision.

Fulltext A review on EEG-based methods for screening and diagnosing alcohol use disorder

Mumtaz W, Vuong PL, Malik AS, Rashid RBA

Cogn Neurodyn, 2018 Apr;12(2):141-156.
PMID: 29564024 DOI: 10.1007/s11571-017-9465-x

The screening test for alcohol use disorder (AUD) patients has been of subjective nature and could be misleading in particular cases such as a misreporting the actual quantity of alcohol intake. Although the neuroimaging modality such as electroencephalography (EEG) has shown promising research results in achieving objectivity during the screening and diagnosis of AUD patients. However, the translation of these findings for clinical applications has been largely understudied and hence less clear. This study advocates the use of EEG as a diagnostic and screening tool for AUD patients that may help the clinicians during clinical decision making. In this context, a comprehensive review on EEG-based methods is provided including related electrophysiological techniques reported in the literature. More specifically, the EEG abnormalities associated with the conditions of AUD patients are summarized. The aim is to explore the potentials of objective techniques involving quantities/features derived from resting EEG, event-related potentials or event-related oscillations data.

Fulltext Shared decision-making in Malaysia: Legislation, patient involvement, implementation and the impact of COVID-19

Lee YK, Ng CJ, Lee PY, Tong WT, Sa'at H

Z Evid Fortbild Qual Gesundhwes, 2022 Jun;171:89-92.
PMID: 35610129 DOI: 10.1016/j.zefq.2022.04.020

Shared decision making (SDM) activities in Malaysia began around 2010. The rise in the numbers of patients with chronic disease in Malaysia underscores a growing need for doctors to practice patient-centred care and SDM as more Malaysians come into regular contact with health decision-making scenarios. Recent guidelines for medical professionalism have emphasized that options and risks be discussed in consultations, especially for procedures with risk of adverse outcomes. Although SDM is not legally required, principles of SDM are applied in legal judgements on informed consent. Research on SDM has grown to include the adoption of patient and public involvement in research, an increased emphasis on incorporating local cultural values in SDM, and implementation of SDM in Malaysia's health system and organizational culture. While COVID-19 hindered the progress of SDM research, one positive development was that vaccination choices heightened public consciousness about personal decisional autonomy and the need to discuss pros and cons with doctors before making a medical decision.

Fulltext Barriers of and strategies for shared decision-making implementation in the care of metastatic breast cancer: A qualitative study among patients and healthcare professionals in an Asian country

Lee PY, Cheong AT, Ghazali SS, Rashid AA, Ong SC, Ong SY, et al.

Health Expect, 2022 Dec;25(6):2837-2850.
PMID: 36098241 DOI: 10.1111/hex.13590

BACKGROUND: Shared decision-making has been shown to improve the quality of life in metastatic breast cancer patients in high-literacy and high-resource settings. However, limited studies have examined the cultural preferences of metastatic breast cancer patients with shared decision-making implementation and the barriers encountered in an Asian setting where societal norms predominate and physician decision-making is at the forefront. This paper aims to identify (1) barriers to practising shared decision-making faced by healthcare professionals and patients and (2) strategies for implementing shared decision-making in the context of metastatic breast cancer management in Malaysia.
METHODS: We conducted a qualitative study involving 12 patients diagnosed with metastatic breast cancer, 16 healthcare professionals and 5 policymakers from surgical and oncology departments at public healthcare centres in Malaysia. Semi-structured in-depth interviews and focus group discussions were conducted. The interviews were recorded, transcribed verbatim and analysed using the thematic approach. Nvivo software was used to manage and analyse the data.
RESULTS: Five main themes emerged from the study: healthcare provider-patient communication, workforce availability, cultural and belief systems, goals of care and paternalism versus autonomy. Other strategies proposed to overcome barriers to implementing shared decision-making were training of healthcare professionals and empowering nurses to manage patients' psychosocial issues.
CONCLUSION: This study found that practising shared decision-making in the public health sector remains challenging when managing patients with metastatic breast cancer. The utilization of decision-making tools, patient empowerment and healthcare provider training may help address the system and healthcare provider-patient barriers identified in this study.
PATIENT OR PUBLIC CONTRIBUTION: Patients were involved in the study design, recruitment and analysis.

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.

How culture influences patient preferences for patient-centered care with their doctors

Sheeran N, Jones L, Pines R, Jin B, Pamoso A, Eigeland J, et al.

J Commun Healthc, 2023 Jul;16(2):186-196.
PMID: 37401877 DOI: 10.1080/17538068.2022.2095098

BACKGROUND: Patient-centered care (PCC) is the prevailing model of care globally. However, most research on PCC has been conducted in Westernized countries or has focused on only two facets of PCC: decision-making and information exchange. Our study examined how culture influences patients' preferences for five facets of PCC, including communication, decision-making, empathy, individualized focus, and relationship.
METHODS: Participants (N = 2071) from Hong Kong, the Philippines, Australia, and the U.S.A. completed an online survey assessing their preferences for exchange of information, autonomy in decision-making, expression and validation of their emotions, focus on them as an individual, and the doctor-patient relationship.
RESULTS: Participants from all four countries had similar preferences for empathy and shared decision-making. For other facets of PCC, participants in the Philippines and Australia expressed somewhat similar preferences, as did those in the U.S.A. and Hong Kong, challenging East-West stereotypes. Participants in the Philippines placed greater value on relationships, whereas Australians valued more autonomy. Participants in Hong Kong more commonly preferred doctor-directed care, with less importance placed on the relationship. Responses from U.S.A. participants were surprising, as they ranked the need for individualized care and two-way flow of information as least important.
CONCLUSIONS: Empathy, information exchange, and shared decision-making are values shared across countries, while preferences for how the information is shared, and the importance of the doctor-patient relationship differ.

Construction 4.0 technology evaluation using fuzzy TOPSIS: comparison between sustainability and resiliency, well-being, productivity, safety, and integrity

Shafei H, Rahman RA, Lee YS

Environ Sci Pollut Res Int, 2024 Feb;31(10):14858-14893.
PMID: 38285259 DOI: 10.1007/s11356-024-31862-9

This study aims to compare the impact of Construction 4.0 technologies on different organizational core values, focusing on sustainability and resiliency, well-being, productivity, safety, and integrity. To achieve that aim, the study objectives are the following: (i) identify the critical Construction 4.0 technologies between core values; (ii) appraise overlapping critical Construction 4.0 technologies between core values; (iii) examine the ranking performance of Construction 4.0 technologies between core values; and (iv) analyze the interrelationships between Construction 4.0 technologies and core values. First, twelve Construction 4.0 technologies were identified from a national strategic plan. Then, the fuzzy technique for order of preference by similarity to ideal solution (TOPSIS) that incorporates subjective and objective weights was used to evaluate the impact of the Construction 4.0 technologies on the five core values. Finally, the collected data was analyzed using the following techniques: fuzzy TOPSIS, normalization, overlap analysis, agreement analysis, sensitivity analysis, ranking comparison, and Spearman correlation. The study findings reveal four critical Construction 4.0 technologies that enhance all five core values: building information modeling (BIM), Internet of Things (IoT), big data and predictive analytics, and autonomous construction. Also, there is a high agreement on the Construction 4.0 technologies that enhance well-being and productivity. Lastly, artificial intelligence (AI) has the highest number of very strong relationships among the core values. The originality of this paper lies in its comprehensive comparison of the impact of Construction 4.0 technologies on multiple organizational core values. The study findings provide valuable insights in making strategic decisions in adopting Construction 4.0 technologies.

International Patients' Travel Decision Making Process- A Conceptual Framework

Khan MJ, Chelliah S, Haron MS

Iran J Public Health, 2016 Feb;45(2):134-45.
PMID: 27114978

BACKGROUND: Role of information source, perceived benefits and risks, and destination image has significantly been examined in travel and tourism literature; however, in medical tourism it is yet to be examined thoroughly. The concept discussed in this article is drawn form well established models in tourism literature.
METHODS: The purpose of this research was to identify the source of information, travel benefits and perceived risks related to movement of international patients and develop a conceptual model based on well-established theory. Thorough database search (Science Direct, utmj.org, nih.gov, nchu.edu.tw, palgrave-journals, medretreat, Biomedcentral) was performed to fulfill the objectives of the study.
RESULTS: International patients always concern about benefits and risks related to travel. These benefits and risks form images of destination in the minds of international patients. Different sources of information make international patients acquaint about the associated benefits and risks, which later leads to development of intention to visit. This conceptual paper helps in establishing model for decision-making process of international patients in developing visit intention.
CONCLUSION: Ample amount of literature is available detailing different factors involved in travel decision making of international patients; however literature explaining relationship between these factors is scarce.

Fulltext Placebo Controlled Trials: Interests of Subjects versus Interests of Drug Regulators

Sasongko TH, Othman NH, Hussain NHN, Lee YY, Abdullah S, Husin A, et al.

Malays J Med Sci, 2017 Aug;24(4):1-4.
PMID: 28951684 DOI: 10.21315/mjms2017.24.4.1

The use of placebo-controlled trials in situations where established therapies are available is considered ethically problematic since the patients randomised to the placebo group are deprived of the beneficial treatment. The pharmaceutical industry and drug regulators seem to argue that placebo-controlled trials with extensive precautions and control measures in place should still be allowed since they provide necessary scientific evidence for the efficacy and safety of new drugs. On the other hand, the scientific value and usefulness for clinical decision-making may be much higher if the new drug is compared directly to existing therapies. As such, it may still be unethical to impose the burden and risk of placebo-controlled trials on patients even if extensive precautions are taken. A few exceptions do exist. The use of placebo-controlled trials in situations where an established, effective and safe therapy exists remains largely controversial.

Fulltext An Integrated MCDM Model for Conveyor Equipment Evaluation and Selection in an FMC Based on a Fuzzy AHP and Fuzzy ARAS in the Presence of Vagueness

Nguyen HT, Dawal SZ, Nukman Y, Rifai AP, Aoyama H

PLoS One, 2016;11(4):e0153222.
PMID: 27070543 DOI: 10.1371/journal.pone.0153222

The conveyor system plays a vital role in improving the performance of flexible manufacturing cells (FMCs). The conveyor selection problem involves the evaluation of a set of potential alternatives based on qualitative and quantitative criteria. This paper presents an integrated multi-criteria decision making (MCDM) model of a fuzzy AHP (analytic hierarchy process) and fuzzy ARAS (additive ratio assessment) for conveyor evaluation and selection. In this model, linguistic terms represented as triangular fuzzy numbers are used to quantify experts' uncertain assessments of alternatives with respect to the criteria. The fuzzy set is then integrated into the AHP to determine the weights of the criteria. Finally, a fuzzy ARAS is used to calculate the weights of the alternatives. To demonstrate the effectiveness of the proposed model, a case study is performed of a practical example, and the results obtained demonstrate practical potential for the implementation of FMCs.
