A comparison Study on User Acceptance of Digital Healthcare Services Among M40 and B40 Community in Selangor: A Study on SELangkah Application

Over time, the global digital healthcare industry has started to take shape with the aim of offering benefits to all residents. Much effort has been put into improving the effectiveness and accessibility of the healthcare system in Malaysia for the benefit of its people. The Selangor state government is working to make all communities safer and healthier places, and one of its initiatives is the SELangkah application. Nonetheless, there are still concern over the take up of digital healthcare services among citizens especially those in the low-income and middle-income communities; B40 and M40. Previous study has shown that different economic status has an impact towards the acceptance level in technology services. Therefore, this study utilises qualitative research method to investigate the state of user acceptance in digital healthcare services among B40 and M40 users in Selangor through the case study of SELangkah application. Focus group discussion was conducted with over 10 participants from Selangor to evaluate and compare the acceptance level of digital healthcare services between both income group with the instrument development were guided by the Extended Technology Acceptance Model (ETAM). The area of group discussion covers users’ perceived usefulness, perceived ease of use, attitude, behaviour, external challenges, and actual use. The findings show that both M40 and B40 group find the application to be beneficial; in addition, they believe there should be more awareness campaign to promote the application to the public. A few clear differences between the acceptance level of the two groups would be the simplicity of the language used in the application, the recommended features, and future needs between the two groups. M40 group find no difficulties to navigate the application but B40 group mention that the used words can be simplify. While M40 group recommended for gamification and high engagement features; the B40 group is looking more at practicality such as more information or linkages to nearby clinic. Nevertheless, both groups did not find major difficulties and they see a lot of benefit of the application. This will form the fundamental basis for future research efforts aimed at closing the technology acceptance gap and enabling a wider population to use technology as a tool to have a healthier life.

Spatio-Temporal Model to Forecast COVID-19 Confirmed Cases in High-Density Areas of Malaysia

The coronavirus 2019 disease has spread across the world. The number of coronaviruses 2019 (COVID-19) cases throughout Malaysia is high in the densely populated state of Selangor. In assisting the early preventive measures, this study utilises time series methods to model and forecast the number of daily positive cases in three Selangor districts: Petaling, Hulu Langat, and Klang. Specifically, the study compares the effectiveness of the Autoregressive Integrated Moving Average (ARIMA), a univariate model and the Generalized Space-Time autoregressive integrated (GSTARI), a multivariate model. For the GSTARI model, uniform and inverse distance weights represent the relationship between locations. The analysed data are from January to August 2021, and the lowest root mean square error (RMSE) is chosen as the best model. The results show GSTARI (1,1) with both spatial weights outperformed ARIMA (0,1,1) in Petaling and Klang but not in Hulu Langat. However, the average RMSE values show that the most accurate and effective for forecasting the number of daily confirmed positive cases in Selangor is using GSTARI. In conclusion, by utilising advanced time series methods such as spatial analysis, this study provides important insights into forecasting trends of infectious diseases like COVID-19 and can help in early preventive measures.

Job Satisfaction and Turnover Intention among Travel Agency Employees in Selangor

Job satisfaction is among the most difficult issues for many business leaders to address. Researchers have widely discussed this problem, yet statistics still show an alarming increase, and various factors cause it to happen often. This study aims to examine the relationship between job satisfaction and turnover intention and investigate the moderating effect of employee gender and years of experience on the relationship. The four workplace satisfaction determinants—career advancement, employee empowerment, pay level, and nature of the work—that affect employee turnover intention are covered in this study. This study involved respondents among the travel agencies’ employees within the state of Selangor, regardless of their working position. A set of questionnaires was distributed to 130 employees from 26 travel agency companies that participated in the study. The results show employee empowerment has a significant negative relationship with turnover intention. It has been also found that the relationship between job satisfaction and turnover intention is significantly moderated by gender and years of experience. This study recommends that further research should use a larger sample size and qualitative methods to gain comprehensive knowledge regarding the phenomenon.

Exploring Barriers to Timely Diagnosis and Treatment of Tuberculosis in Selangor, Malaysia: A Qualitative Study.

Tuberculosis (TB) occurs as one of the highest in the state of Selangor, Malaysia and its causes are currently underexplored especially from patients' perspectives of the disease. This study assesses perspectives from patients in relations to determinants of delayed presentation, diagnosis, and treatment of TB. The study utilises a qualitative methodology involving focus group discussions and in-depth interviews with patients selected based on specific inclusion and exclusion criteria. The research covered components which include social demographic, sociocultural factors, health-seeking behaviors, social support and resources, previous knowledge and experience as a TB patient, and treatment pathway. Thematic analysis was performed using NVivo 12 analysis software to interpret the data. This study aims to identify key barriers and facilitators of prompt presentation and diagnosis of TB patients. Results revealed that socioeconomic status, challenges faced during TB diagnosis and treatment, knowledge of TB, patient and healthcare-related factors, and health-seeking behaviours were the main emerging themes. Improvements are required in the areas of access to healthcare facilities, minimizing cost, providing specific clinics and proximity of health facilities to facilitate a prompt response, increasing capacity to isolate infected persons, and provision of adequate treatment. It is revealed that financial constraints, inaccessibility and long distance to healthcare facilities, poor knowledge of TB, and lack of family and social support contributed to delayed TB presentation and diagnosis. Findings from this study can be utilized to develop effective, locally tailored interventions to address delayed presentation and diagnosis of TB patients in the nation.

Two new species of Austrelatus diving beetles from continental Southeast Asia, linking the distribution area of the genus (Coleoptera: Dytiscidae: Copelatinae)

Two new species of predominantly Australasian genus Austrelatus Shaverdo et al., 2023 are described and illustrated: Austrelatus mirai sp. nov. from Selangor State in Peninsular Malaysia is similar in habitus to the South Indian species A. boukali (Hendrich & Balke, 1998) and A. davidi (Wewalka, 2017); however, the shape of the male genitalia suggests that it is closely related to Austrelatus species from Kalimantan. Austrelatus riberai sp. nov. from Shan State in Myanmar is most similar to Sino-Japanese A. parallelus (Zimmermann, 1920). Findings of Austrelatus species in continental Southeast Asia fill the gap in the distribution area of the genus between India, China and Japan on one side, and the Sunda Islands on the other side.

Prevalence of offering menopause hormone therapy among primary care doctors and its associated factors: A cross-sectional study.

Guidelines recommend Menopausal Hormone Therapy (MHT) as the most effective treatment for menopausal symptoms. However, a local study found that the usage of MHT among menopausal women was low (8.1%), with one of the main reasons being it is not recommended by doctors. Therefore, the objectives of this study are to determine the prevalence of offering MHT in treating symptomatic menopausal women among primary care doctors (PCDs) and its associated factors. This cross-sectional study involved PCDs from the Federal Territory of Kuala Lumpur, the Federal Territory of Putrajaya and the state of Selangor. All PCDs provided services in government primary care clinics from the three states were invited through the doctor in charge of each clinic. An online survey links was provided for the participants to the self-administered questionnaire. The questionnaire included PCDs' demographics, their menopause management practices, attitudes towards MHT, perceived barriers in offering MHT, knowledge of related guidelines and received training on menopause management. The outcome variable was offering MHT which defined as either prescription of MHT or referral to hospital for MHT initiation. Multivariate logistic regression analysis was performed to determine the factors associated with offering MHT. The response rate was 42.9% (559/1301). Of those who participated in the study, 77.8% of PCDs were female and 89.1% were medical officer. Although 66.9% of the participants reported offering MHT to their patients, the actual prescription rate was low (0.9%). Most PCDs (66%) would refer the patients to hospitals. 87.1% of PCDs (487/559) reported that MHT was not available in their clinic. In the past 12 months, 83% of PCDs had not received any related training. Female PCDs (AOR:2.5, CI: 1.51-4.13, p<0.001), perceiving MHT as preference treatment for menopause symptom (AOR:3.6, CI: 2.13-6.19, p < 0.001), having likelihood to recommend MHT to family and friends (AOR:3.0, CI: 1.87-4.83, p < 0.001), and receiving training on menopause management (AOR:2.7, CI: 1.30-5.56, p = 0.008) were the positive predictor of offering MHT. The negative predictors in offering MHT were no-experience in prescribing MHT (AOR: 0.4, CI: 0.15-0.87, p = 0.024) and lack of information regarding MHT for the patient (AOR: 0.4, CI:0.20-0.67, p < 0.001). The study revealed a low rate of MHT prescription among PCDs, with many relying on referrals to hospitals for managing menopausal symptoms. The findings underscore the need for strategies that includes fulfilling professional training gaps, improving MHT availability, and improving information dissemination for patient.

Perspective of Private Kindergarten Teachers on Pre-Coding Program in Early Childhood Education / Pandangan Guru Tadika Swasta Terhadap Program Pre-Coding dalam Pendidikan Awal Kanak-Kanak

Nowadays, learning coding has become a highly demanded teaching method to apply basic skills such as programming and computational thinking (CT) in line with current technological developments. Malaysia also takes this issue into account by introducing a pre-coding program for early childhood education. Pre-coding is an activity that teaches the concept of coding which is looking at computational thinking (CT) such as problem solving, logical thinking and creative thinking without involving the use of digital devices. This is because pre-coding is seen as more appropriate to be implemented for children in line with their developmental level who are in dire need of exploring the real world through physical activity. Therefore, this study aims to identify the views of private kindergarten teachers on pre-coding in early childhood education. This teacher's view is seen from the aspects of knowledge, awareness, interest and acceptance of the teacher about the pre-coding program in early childhood education. This study uses a quantitative research design with a cross-sectional survey method. A total of 144 private kindergarten teachers around the states of Perak, Selangor and Putrajaya were selected as the study sample. The research instrument uses a set of questionnaires to answer the research objectives by looking at the median value for each aspect. The findings of the study show that the median value is high for the aspects of knowledge, awareness, interest and acceptance of teachers about pre-coding for children. The study found that the median value of all four aspects is equal to a value of 4. Therefore, the implementation of the pre-coding program is very important to be introduced and implemented in the early teaching and learning of children to help children acquire new basic skills in line with the development of the world of technology.

The support and influence of the family on the career decisions of Young Orang Asli in Selangor

The government's development agenda is applied to all communities, especially indigenous populations, in the fields of education and the economy. In order to achieve and preserve the living well-being of indigenous communities, a development programme is provided that includes the provision of high-quality human resources, such as youths, who can improve their families' standard of living. It encompasses not just economic activities but also elements of family, education, and social development. In addition, this article aims to identify the influence and support of families such as parents in helping young natives make decisions to choose a job that can improve the well-being of the community and their families, especially in economic terms. This study is quantitative and has a survey-style design. A survey instrument that was given to 281 indigenous teens in the state of Selangor at random was used to collect the survey data. Research has shown that the majority of indigenous teens' decisions to work are influenced by and dependent on their families, particularly their parents. A contributing component to the results was the motivation to support their families' economic growth. This study suggests that, despite their poor economic and educational standards, indigenous societies have strong family relationships. Young indigenous use their family bonds as a source of motivation while making decisions about their work.

Qualitative Assessment on the Impact of Family-Based Drug Prevention Program by the National Anti-Drugs Agency in Malaysia

Family-based prevention programs aim to prevent youth from falling victim to substance abuse issues by focusing on what families can offer. This study attempts to evaluate the effectiveness of the Family on Alert (FoA) program conducted by NADA. A qualitative method was utilized involving focus group discussions with key informants from NADA in the state of Selangor, Kedah, Johor, Sabah, and the Federal Territory of Kuala Lumpur. NVivo software was used to analyze the qualitative data. Generally, the FoA program implemented by NADA has positively impacted the participants, particularly in increasing the awareness, knowledge, and attitude among parents in preventing drug abuse among adolescents in Malaysia.

Seroprevalence and contributing factors of transboundary animal diseases in sheep and goats: a study in Peninsular Malaysia.

Diseases caused by small ruminant lentiviruses, Mycobacterium avium ssp. paratuberculosis (MAP), Schmallenberg virus, and peste des petits ruminants virus (PPR) is globally recognised as serious threats to the ruminant industry due to their potential to spread rapidly across boundaries. Despite their global distribution and negative impacts on ruminant production, there is a gap in knowledge of the current trends in their epidemiology among sheep and goat populations in Peninsular Malaysia. This study was therefore designed to fill the gap of knowledge concerning the seroprevalence and contributing factors of CAEV, paratuberculosis, SBV, and PPRV among small ruminants from selected flocks in Selangor, Negeri Sembilan, and Pahang states in Peninsular Malaysia. A cross-sectional study design was used to collect animal data and blood samples for serological assays simultaneously. The ID Screen (ID.VET, France) indirect ELISA screening tests were used to detect serum antibodies directed against CAEV/MVV (VISNAS Ver 0922), paratuberculosis (PARAS Ver 0516), SBV (SBVC Ver 1114) and PPRV (PPRC Ver 0821). There was 45.4% (95% CI = 40.74-50.74), 6.8% (95% CI = 4.66-9.69), 27.8% (95% CI = 23.35-32.77), and 2.6% (95% CI = 1.11-0.51) true seroprevalence for CAEV, paratuberculosis, SBV, and PPR, respectively. Geographical location and species were the risk factors for CAEV and paratuberculosis, while the management system and age of small ruminants were the risk factors for SBV. The present study is the first to document a large-scale seroprevalence of MAP and PPR infection among sheep and goat flocks in Peninsular Malaysia. The presence of PPRV and MAP antibodies among small ruminant flocks is signalling current or previous exposure to the pathogens or cross reactions with similar antigens. This finding further suggests the potential for future outbreaks of these devastating diseases among sheep and goats in Malaysia. The high seroprevalence of CAEV and SBV among small ruminants indicates high levels of exposure to the viruses in the environment, which is a potential threat to production.

Using sustainability pillar indicators to evaluate the management effectiveness of three protected areas in the state of Selangor, Peninsular Malaysia

The existing methodologies to measure management effectiveness of protected area have often been focus on identifying weaknesses and strengths to set priorities in terms of policy intervention, resource distribution and adaptive management. It is not adequately captured the extent of protected area sustainability as a conservation site even though management effectiveness is influenced by the interaction of environment, socioeconomics and governance, which are pillars of sustainability. Thus, the objective of this study was to propose a methodology based on sustainability pillar indicators to evaluate management effectiveness, using three protected areas in Peninsular Malaysia as case studies: Sungai Dusun, Bukit Kutu and Klang Gate wildlife reserves. In this study, a questionnaire survey was used to evaluate the management effectiveness of the study sites. The evaluation framework of the questionnaire was based on six components of management effectiveness and indicators from three sustainability pillars or aspects: environment, socioeconomics and governance. Respondents of the survey consisted of local residents in each study site and management staff involved in the management of the protected areas. Each indicator from different aspects of evaluation was assigned a selected parameter to be rated by the respondents from ‘1’ (strongly disagree) to ‘5’ (strongly agree). Based on the rating values the percentage of optimum value was calculated to determine the overall management rating for each study site which interpreted according to five management levels from ‘unsatisfactory’ to ‘very satisfactory’. The percentage of optimum values revealed that the environment and governance aspects of all study sites had moderately satisfactory while for socioeconomic only Klang Gate had moderately satisfactory but satisfactory for Bukit Kutu and Sungai Dusun. The overall percentage of optimum revealed that the management effectiveness level of all reserves was moderately satisfactory. However, Sungai Dusun had the highest percentage of optimum (71.3%), followed by Bukit Kutu (67.7%) and Klang Gate (66.5%). In conclusion, the sustainability level of the reserves is still functioning as intended despite deficiencies especially in governance aspect. Thus, the proposed methodology is simple and has adoptable way to measure both management effectiveness and capture the sustainability of the protected areas.

This paper aims to investigate the impact of service quality on customer satisfaction for mobile users in Malaysia. Specifically, this paper examined the impact of service quality dimensions (tangibility, reliability, responsiveness, assurance, empathy) on customer satisfaction in the post-COVID era. The data were collected by using a self-administered questionnaire to the sample of Kuala Lumpur and Selangor states mobile users. Overall, 117 responses were gathered and five hypotheses were tested using hierarchical regression analyses. The results are mixed. Out of five hypotheses, only two were accepted. Reliability and responsiveness were found significantly positive relation to customer satisfaction whereas tangibility, assurance, and empathy were shown otherwise. Lastly, the discussion part will deliberate on the conflicting results. The limitations and suggestions for future research are also presented.

Moral Emotion and Moral Identity on Moral Judgement Maturity Among Malaysian Secondary School Students

In preparation for the challenges of the real world and life after school, moral judgement stands as a pivotal skill among Malaysian secondary school students. Understanding the moral motivating factors contributing to the development of moral judgement maturity is imperative. Therefore, this study aims to analyze the relationships between moral motivation components—specifically, moral emotion (guilt and shame) and moral identity—and moral judgement among Malaysian secondary school students. A sample of 393 students (170 males, 223 females; M age = 16 years) from Selangor state participated in the study. Structural equation modelling (SEM) was utilised to analyse the predictive associations between these constructs. The findings revealed positive correlations among moral emotion, moral identity, and moral judgement. Notably, both guilt and shame, as well as moral identity, were found to be significantly related to students' moral judgement maturity. These results suggest that the tendency for experiencing guilt and shame, along with a heightened moral identity, play pivotal roles in shaping the moral judgement maturity of secondary school students, potentially fostering their moral development. This study contributes valuable insights into the mechanisms linking emotions and identity to moral judgement maturity, offering significant implications for the field of moral psychology.

Enhancing knowledge, attitude, and perceptions towards fall prevention among older adults: a pharmacist-led intervention in a primary healthcare clinic, Gemas, Malaysia

BackgroundFalls and fall-related injuries are very common among older adults, and the risk of falls increases with the aging process. The lack of awareness of falls and fall-related injuries among older adults can contribute to an increasing risk of falls. Hence, a study was carried out to improve the knowledge, attitude, and perception of falls and fractures among older adults in a primary care setting in Gemas, a rural area of the Selangor state of Malaysia.MethodA structured educational intervention was provided to older adults who visited the primary care setting in Gemas and provided written informed consent to participate in the study. A total of 310 older adult patients was included in the study using a convenience sampling technique.ResultsBefore the intervention, 74.84% of the respondents (n = 232) agreed that falls and related fractures are the leading causes of hospital admission among older adults. In post-intervention, the number of respondents who agreed with this statement increased to 257 (82.91%). At baseline, 28 respondents (9.03%) had poor knowledge, 160 respondents (51.61%) had average knowledge levels, and 122 respondents (39.35%) had good knowledge. In post-intervention, respondents with poor and average knowledge reduced to 1.93% (n = 6) and 29.35% (n = 91) respectively. A majority of respondents’ knowledge levels improved significantly after the intervention (n = 213; 68.71%). About eight respondents (2.58%) had a negative perception of falls. In post-intervention, the percentage reduced to 0.65% as only two respondents had a negative perception. A total of 32 types of fall-risk-increasing drugs (FRIDs) have been prescribed to the respondents. A strong correlation (r = 0.89) between pre- and post-intervention knowledge was shown among the respondents. Paired t-test analysis showed a statistically significant difference.ConclusionThe pharmacist-led educational intervention significantly improved the knowledge, attitude, and perception of falls among older adults. More structured and periodical intervention programmes are warranted to reduce the risk of falls and fractures among older adults.

Criminological Insights: A Comprehensive Spatial Analysis of Crime Hot Spots of Property Offenses in Malaysia's Urban Centers

This study examines property crime trends in Selangor, Kuala Lumpur, and Putrajaya from 2015 to 2020, utilizing Geographic Information Systems (GIS) and comprehensive crime data from the Royal Malaysia Police. It focuses on the relationship between property crime rates and the delineation of police station jurisdictions across Selangor State, Kuala Lumpur Federal Territory (KLFT), and Putrajaya Federal Territory (PFT). The objective is to understand the dynamics of property crime, its evolution, and the influence of the National Transformation Program on crime prevention strategies. By assessing the spatial distribution of property crimes, this research aims to identify underlying trends and the efficacy of hot spot policing. The analysis is underpinned by an extensive review of secondary data from the Intelligence/Operations/Records Division of the Royal Malaysia Police Headquarters, enabling a deep dive into the spatial characteristics of property crime within these regions. The findings contribute to the broader understanding of crime prevention in Malaysia, underscoring the importance of GIS technology and the need for strategic interventions tailored to specific crime patterns. This study provides critical insights for policymakers and law enforcement to formulate evidence-based strategies, enhance public safety, and inform future crime prevention efforts.

Factors associated with poor appetite among residents at selected long-term care facilities in Selangor, Malaysia

Introduction: Poor appetite is prevalent among older adults and may negatively impact on their overall health. This is especially true for institutionalised residents. Despite this, there is a paucity of research on appetite and its associated factors among institutionalised residents, which signified the present study. Methods: A cross-sectional study was conducted among elderly residents at long-term care facilities in the state of Selangor, Malaysia to ascertain their appetite status and its associated factors. Results: A total of 97 residents with mean age of 74.2±8.4 years old were recruited. They comprised 61.9% females and 38.1% males. More than 50% had poor appetite with early satiety. There were 63.0%, 82.4%, and 94.8% who had poor oral health, poor sleep quality, and depression, respectively. Ethnicity (OR=2.73; 95% CI=1.00-7.44; p=0.049) was the only factor that predicted poor appetite among older adults in long-term care facilities, with Malay residents having poorer appetite than their Chinese and Indian counterparts. Conclusion: The prevalence of poor appetite was high among residents staying at long-term care facilities in Selangor, Malaysia, especially among Malays. This issue deserves further studies to identify the specific underlying factors contributing to poor appetite among older adults from different ethnicities. Acknowledging the high prevalence of poor appetite among older adults and its possible unfavourable outcomes, appropriate nutrition interventions are therefore needed to address this issue among institutionalised elderly.

The Mediating Role of Attitudes towards Performing Well between Ethical Leadership, Technological Innovation, and Innovative Performance

The business sector is rife with unethical managerial practices, such as blaming subordinates for organizational failings, along with the exploitation of colleagues, favoritism, and conflicts of leadership. In light of this, numerous researchers have endeavored to explain the phenomenon of ethical perspectives and concerns. It is recommended that organizations in the SME sector adopt ethical practices in order to achieve their long-term objectives. This study stresses the influence of ethical leadership and technological innovation, particularly the mediating role of a positive attitude in encouraging good performance. This study, which was conducted in the SME sector of Malaysia in the state of Selangor, employed a convenience sampling technique for data collection and reports that ethical leadership, technological innovation, and attitude significantly influence performance. A mediating role of attitude in relation to technological innovation and innovative performance is hereby reported, and attitude towards performance was found to have an insignificant effect on ethical leadership and innovative performance. This study contributes to the existing body of knowledge by explaining the role of ethical leadership and technological innovation in expressing and assessing the revolutionary business practices required to ensure organizational success.

Exploring the Driving Factors behind Traditional Food Entrepreneurs in Sabah and Selangor

his study explores the key factors influencing local entrepreneurs in Sabah and Selangor states in selling traditional food. Twenty (20) informants from various business categories are identified and interviewed using a qualitative method. The transcript interview is being analysed to develop code and theme. Results showed there are two (2) themes that have been identified: 1) criteria for traditional food (cooking method, flavour, and originality) and 2) demand for traditional food (history, origin of food). Findings show the key factors that drive local entrepreneurs to develop distinctive attractions and become new tourism destinations, especially in traditional food areas

Investigating Escherichia coli habitat transition from sediments to water in tropical urban lakes.

Escherichia coli is a commonly used faecal indicator bacterium to assess the level of faecal contamination in aquatic habitats. However, extensive studies have reported that sediment acts as a natural reservoir of E. coli in the extraintestinal environment. E. coli can be released from the sediment, and this may lead to overestimating the level of faecal contamination during water quality surveillance. Thus, we aimed to investigate the effects of E. coli habitat transition from sediment to water on its abundance in the water column. This study enumerated the abundance of E. coli in the water and sediment at five urban lakes in the Kuala Lumpur-Petaling Jaya area, state of Selangor, Malaysia. We developed a novel method for measuring habitat transition rate of sediment E. coli to the water column, and evaluated the effects of habitat transition on E. coli abundance in the water column after accounting for its decay in the water column. The abundance of E. coli in the sediment ranged from below detection to 12,000 cfu g-1, and was about one order higher than in the water column (1 to 2,300 cfu mL-1). The habitat transition rates ranged from 0.03 to 0.41 h-1. In contrast, the E. coli decay rates ranged from 0.02 to 0.16 h-1. In most cases (>80%), the habitat transition rates were higher than the decay rates in our study. Our study provided a possible explanation for the persistence of E. coli in tropical lakes. To the best of our knowledge, this is the first quantitative study on habitat transition of E. coli from sediments to water column.
