Insulin therapy is a recommended treatment for diabetes mellitus. Despite knowing insulin is one of the recommended treatments for glycemic control, adherence to insulin therapy still plays the main challenge in achieving good control of glycated haemoglobin (HbA1c). This study aims to determine adherence and compare HbA1c levels before and after six months of insulin therapy among type 2 diabetes patients (T2DM). This cross-sectional study was conducted among 300 participants with T2DM at Sungai Buloh community health clinic, Selangor. A self-administered questionnaire Morisky Insulin Adherence Scale (MIAS), was used to measure the study adherence variable. Data were analysed using a statistical package for the social science (SPSS) version 23. 11 (3.7%) of respondents had good adherence,109 (36.3%) had moderate adherence, and 180 (60%) were poor adherence. The mean HbA1C at baseline is 9.654 mmol/L and reduced to 9.194 mmol/L after six months of insulin therapy. Education shows an association towards adherence level with p-value = 0.004 and significantly found an association between HbA1c and insulin adherence with p < 0.05. The study found that most respondents have poor adherence to insulin therapy. Therefore, essential to highlight adherence issued to achieve good glycaemic control.

Cataract is the leading cause of blindness worldwide. This study aimed to assess and compare the awareness levels about cataracts leading to visual impairment between health sciences and non-health sciences university students. A comparative cross-sectional study design was conducted on 432 participants aged 19 to 27 (mean 22.75 ± 1.90), with an equal number of 216 participants from health sciences and non-health sciences students. The data was collected using a questionnaire through an online platform (Google Form). Most respondents (81.5%) had heard about cataracts and knew that cataract incidence increases with age. Most respondents (72.2%) were aware that radiation risks cataracts. 20.1% of the respondents did not aware that cataract surgery is free in government hospitals for certain circumstances. Cataract awareness was statistically higher among health sciences students (1.73 ± 0.13) compared to non-health sciences students (1.52 ± 0.16), t(430) = 13.68, p = 0.001. More than half of the respondents were aware of cataracts and their risk factors, but some still did not know about government hospitals’ free cataract surgery service. High awareness among university students will undoubtedly benefit them and raise awareness of those around them, including their families.
白内障是全世界致盲的主要原因。本研究旨在评估和比较健康科学与非健康科学大学生对白内障导致视力损害的认知水平。采用比较横断面研究设计对432名年龄19 ~ 27岁(平均22.75±1.90)的参与者进行研究，其中216名参与者来自健康科学和非健康科学的学生。数据通过在线平台(Google Form)使用问卷收集。大多数受访者(81.5%)听说过白内障，知道白内障发病率随年龄增长而增加。大多数受访者(72.2%)知道辐射会导致白内障。20.1%的受访者不知道公立医院在某些情况下白内障手术是免费的。健康科学专业学生的白内障知知率(1.73±0.13)高于非健康科学专业学生(1.52±0.16)，t(430) = 13.68, p = 0.001。超过一半的受访者了解白内障及其危险因素，但仍有一些人不知道政府医院的免费白内障手术服务。大学生的高意识无疑会使他们受益，并提高他们周围的人，包括他们的家人的意识。

The main purpose of this study is to determine the main barriers to learning PE with Coach’s Eye mobile application (TechSmith Corp.) and mobile device. We used an Interpretive Phenomenological Analysis (IPA) approach and found that undergraduate Physical Education (PE) pre-service teachers feared failure when learning sports skills with technology after completing the intervention for six weeks. Despite the intervention group improving their sports skills more than the control group, they also reported a higher tendency of bias when learning sports skills with technology. The participants also highlighted reduced practice time and added responsibilities as a hindrance to this method’s adoption. Our work answers the questions regarding participants’ perceived barriers, technological literacy towards learning sports skills, and motivation to embrace teaching and learning with technology. We also suggested the potential benefits of learning PE with technology for students and educators which warranted future studies to find solutions to mitigate pre-service PE teachers’ concerns about using technology in their teaching sessions. Additionally, future studies are needed to expand our understanding of learning with technology in other sports categories (e.g., invasion, target), the context of learning, and the cognitive ability of various populations.

Distal Radius Fracture (DRF) is the most common upper limb fracture, which reduces independence in daily living activities. This study explored the functional recovery of distal radius fracture six months post-injury. We conducted a qualitative study using an Interpretive Phenomenological Analysis (IPA). 11 adults aged 18 and 59 with DRF participated in face-to face, semi-structured, and in-depth interviews recorded digitally. In addition, transcribed recordings were analysed thematically. Four themes emerged from the analysis: (i) I could do or could not do, (ii) How I live my life, (iii) What I feel like, and (iv) Something is wrong with my hand. Following over six months of injury, all participants experienced physical limitations where most participants reported reduced daily activities performance. Consequently, some participants developed adaptive strategies to enhance their daily activities’ ability. DRF also affected their psychological aspects. Overall, DRF affects individuals’ functioning in daily living activities, work and leisure for over six months post-injury. This study highlights that occupational therapists need to maintain or strengthen functional recovery and support individuals with DRF even for over six months post-injury.

: Farm management must have proper planning on the resources such as fertiliser, labour, water and pesticide. Fertiliser provides healthy growth to the plant. It is one of the important resources the farm needs. Thus, the usage and allocation of fertilisers must be managed wisely to avoid wastage that incurs costs. This paper presents a case study which focuses on the nutrient management of rubber plantations. The main objective is to minimise the cost of chemical fertilisers used to plant rubber. Besides, the sub-objectives are to determine the best weight combination for fertilisers and calculate the mass per hectare of Nitrogen, Phosphorus, and Potassium needed for the rubber trees. The goal programming approach has been applied to solve the problem. In the model formulation, there are seven decision variables representing chemical fertilisers, while the constraints are the cost of chemical fertilisers and the requirement of the upper and the lower limit of nutrients in the chemical fertilisers. Results indicate that this method can meet all the goals expected. In conclusion, this study shows that goal programming is suitable for modelling plant input, cost and constraint of rubber farm management.

Given the global environmental degradation due to conventional food consumption and demand, sustainable food consumption (organic food) counters the deterioration by increasing consumers’ sustainable food consumption. As organic food development in Malaysia remains in its infancy as a niche market, research on green marketing with localised applications remains scarce and does not significantly catalyse organic food demand. The study investigates the consumers’ attitudes, perceived social pressure, autonomy, and receptivity to green communication toward organic food purchase intention. The study applied a causal analysis where a quantitative method was employed. Purposive sampling was employed in the study, where primary data was used for analysis through an online survey. The survey employed five Likert scale measurements where data were collected in Malaysia, and 268 valid responses were obtained. The data were analysed using SPSS and AMOS software. The finding revealed a significant influence of personal attitude, perceived autonomy, and receptivity to green communication on organic food purchase intention. Perceived social pressure did not indicate a statistically significant relationship towards organic food purchase intention. Receptivity to green communication was found to be statistically insignificant as a moderator. Stakeholders and organic food producers may benefit from the study’s detailed analysis of the market’s current state to better predict its growth and ensure the industry’s long-term viability.

Socio-spatial transformation of urban architecture is a process that changes the elements of urban architecture and its formers. Development in coastal areas always impacts local communities on the coast. Sometimes they experience a process of change that requires them to adapt and even integrate situationally. This study aims to describe the socio-spatial transformation reality of contemporary urban architectural elements through a phased dynamic from the perspective of local communities in urban coastal areas. The method is conducted by qualitative research method. This is a single case study to identify a specific case used to study real-life cases of the initiation of adaptation and integration of local communities. Data were obtained through participant observation, documentation and inductive in-depth interviews and focus group discussions that focused on descriptive theme analysis to understand the process of socio-spatial transformation of urban architectural elements in urban coastal local communities. The result of this study is a cycle of socio-spatial transformation of urban architectural elements is formed, consisting of (1) the natural, normal phase; (2) the adaptation initiation phase; and (3) the integration phase.

The prevalence of myopia is increasing worldwide, mainly in Asian countries. Light-emitting Diodes (LED) and low light levels used for homework after school was thought to contribute to myopia development. This study explored how near work and lighting affect the accommodation response. 30 myopic young Malay adults (18-23 years old) were recruited. The ASRC was measured after performing a 30-min near the electronic task at 20 cm using a binocular open-field autorefraction (Grand Seiko, Shin-Nippon) at 6.0 m, 1.0 m, 0.5 m, 0.33 m, 0.25 m, and 0.20 m under four different lighting conditions (Fluorescent 6500K, Fluorescent 3000K, LED 6500K, LED 3000K). A significant flattening in the ASRC gradient was noted when comparing pre and post-measures following the near-vision task for all lighting conditions (p < 0.01). ASRC gradient differences were not affected by lighting conditions (One-way repeated measure ANOVA F (3,87) = 0.84, p > 0.05). ASRC gradient was affected only after 30 minutes of near work F (3,87) = 0.049, p < 0.05). The increment in the accommodative inaccuracy was apparent following prolonged close work. Types of light were not imperative. This information on short-term exposure can be useful for interior light choice of buildings. The effect of long-term exposure requires further investigation.

Many individuals nowadays enjoy eating various types of local fruits without realising the impact of the fruits on blood group antigens. The fruit lectin can cause damage to the mucosal surface in the gut when the lectin is incompatible with blood group antigens. Therefore, the present study aims to determine the in vitro plant lectins reaction from the extraction of Artocarpus heterophyllus Lam. (Jackfruit), Artocarpus altilis (Parkinson ex F.A.Zorn), Fosberg (Breadfruit), Carica papaya (Papaya), Manilkara zapota (L.) P. Royen (Sapota) and Salacca zalacca (Gaertn.) Voss (Salak) with specific human blood group antigens. The local fruit extract was tested with human blood groups A and B for hemagglutination assay. The agglutination titer of the hemagglutination assay results was then evaluated. The total of 3+ reactions for jackfruit was 11%, salak (4%) and papaya(6%) for both blood groups. The breadfruit shows the highest titer reaction, 19% against A and 16% against B. In comparison, 19% was against A for sapota but only 4% towards group B. The highest titer value of erythrocytes by crude lectins of selected local fruits on blood groups A and B was given by extraction of sapota while for blood group B on papaya. This discovery proves that plant lectins from five varieties of local fruits react with blood group antigens and that comparable interactions may occur at the mucosal surface of the gut in susceptible individuals, causing significant inflammation, swelling, and ulceration. The mechanism and effect of fruit lectin on human blood types should be investigated further.

The fruit lectin can cause damage to the mucosal surface in the gut when the lectin is incompatible with blood group antigens. Therefore, the present study aims to determine the in vitro plant lectins reaction from the extraction of Artocarpus heterophyllus Lam. (Jackfruit), Artocarpus altilis (Parkinson ex F.A.Zorn), Fosberg (Breadfruit), Carica papaya (Papaya), Manilkara zapota (L.) P. Royen (Sapota) and Salacca zalacca (Gaertn.) Voss (Salak) with specific human blood group antigens. The local fruit extract was tested with human blood groups A and B for hemagglutination assay. The agglutination titer of the hemagglutination assay results was then evaluated. The total of 3+ reactions for jackfruit was 11%, salak (4%) and papaya(6%) for both blood groups. The breadfruit shows the highest titer reaction, 19% against A and 16% against B. In comparison, 19% was against A for sapota but only 4% towards group B. The highest titer value of erythrocytes by crude lectins of selected local fruits on blood groups A and B was given by extraction of sapota while for blood group B on papaya. This discovery proves that plant lectins from five varieties of local fruits react with blood group antigens and that comparable interactions may occur at the mucosal surface of the gut in susceptible individuals, causing significant inflammation, swelling, and ulceration. The mechanism and effect of fruit lectin on human blood types should be investigated further.","PeriodicalId":17041,"journal":{"name":"JOURNAL OF SUSTAINABILITY SCIENCE AND MANAGEMENT","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136369021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acetaminophen is a common antipyretic and analgesic pharmaceutical contaminant and has become one of the most emerging contaminants in the environment. Bioremediation is the suitable method to degrade acetaminophen as it is sustainable, mimics nature and is low-cost. The bioremediation of acetaminophen is performed by identifying the bacterial characteristics and the source of the bacteria involved in the degradation of acetaminophen. Based on this review study, gram-negative bacteria showed the highest efficiency in degrading acetaminophen by Pseudomonas aeruginosa strain HJ1012 and Cupriavidus necator with an efficiency of 99% and 100%, respectively. In addition, synergistic or antagonistic interaction among bacteria in mixed culture is a gap of study. The findings from the previous study showed that the optimum conditions are pH 7.0, temperature ranges between 30–40°C, and a poor culture medium of minimal salt solution. Furthermore, the study sheds light on enzyme involvement and characterisation of acetaminophen degradation pathways toward less harmful intermediates are addressed in order to achieve sustainable development goals through environmental security and health safety. These identified research gaps offer fundamental knowledge and shed insight into upcoming mechanism and application studies.
