Sensors (Basel), 2020 Nov 25;20(23).
PMID: 33255797 DOI: 10.3390/s20236744

Photovoltaic (PV) systems need measurements of incident solar irradiance and PV surface temperature for performance analysis and monitoring purposes. Ground-based network sensor measurement is preferred in many near real-time operations such as forecasting and photovoltaic (PV) performance evaluation on the ground. Hence, this study proposed a Fuzzy compensation scheme for temperature and solar irradiance wireless sensor network (WSN) measurement on stand-alone solar photovoltaic (PV) system to improve the sensor measurement. The WSN installation through an Internet of Things (IoT) platform for solar irradiance and PV surface temperature measurement was fabricated. The simulation for the solar irradiance Fuzzy Logic compensation (SIFLC) scheme and Temperature Fuzzy Logic compensation (TFLC) scheme was conducted using Matlab/Simulink. The simulation result identified that the scheme was used to compensate for the error temperature and solar irradiance sensor measurements over a variation temperature and solar irradiance range from 20 to 60 °C and from zero up to 2000 W/m2. The experimental results show that the Fuzzy Logic compensation scheme can reduce the sensor measurement error up to 17% and 20% for solar irradiance and PV temperature measurement.

This study examines the factors that influence organizational commitment among public employees in
residential colleges in the University of Malaya. A total of 100 employees representing 12 colleges
responded to the questionnaires that were designed to measure their motivation and level of
commitment. The data obtained were analyzed using correlation, analysis of variance and regression
analysis were used in order to achieve the objectives of the study. The findings of this study indicated
that there are significant and positive relationships between all factors (employment compensation,
training and development, career development and management support) with organization
commitment. Furthermore, the findings also showed a directional relationship between independent
and dependent variables by which the public employees at the colleges have positive commitment to
the organization when the management provides attractive training and development, career
development and good management support. In addition, the findings indicated that career
development was the most dominant factor influencing organizational commitment followed by
training development and job compensation. However, management support factor does not affect the
organizational commitment among public employees compared to the other factors.

Saravanan S, Zairul Anuar KB, Zulkefli A, Ramanathan R

Med J Malaysia, 2014 Oct;69(5):216-8.
PMID: 25638234 MyJurnal

OBJECTIVE: The aim is to find rate of return to work of surgically treated thoracolumbar fracture patients and to know if back pain, compensation issues or neurological status influence this rate.

METHODOLOGY: A retrospective cohort study analysing the patients with thoracolumbar fractures treated surgically from January 2008 till December 2009.

RESULTS: Neurological status is the main factor deciding return to work in this group. Back pain and compensation related issues were not statistically significant in influencing return to work. 74% of patients in this group return to work.

CONCLUSION: Return to work among the patients with thoracolumbar fracture, treated surgically, is mainly dependent on neurological status and not the compensation related issues or back pain.

Homofobia dalaman dikaitkan dengan perasan negatif yang dirasai oleh seseorang lelaki gay dan menjadi konflik dalaman di dalam dirinya. Homofobia dalaman yang dialami oleh lelaki gay merupakan salah satu petunjuk mengapa mereka mencari sebab untuk berkahwin dengan wanita. Oleh itu, kajian ini bertujuan untuk mengkaji tahap homofobia yang dialami oleh lelaki gay di Malaysia serta melihat pengaruhnya di dalam menentukan alasan lelaki gay memilih untuk berkahwin atau tidak berkahwin dengan seorang wanita. Responden yang terlibat di dalam kajian ini adalah seramai 29 orang yang dipilih daripada laman sosial Facebook, e-mel, kampus UKM Bangi serta sekitar Kuala Lumpur dan Selangor. Satu set borang soal selidik mengandungi item latar belakang demografi, Internalized Homophobia Scale, serta soalan terbuka tentang alasan lelaki gay berkahwin dan tidak berkahwin dengan wanita telah diedarkan kepada responden. Hasil kajian mendapati bahawa tahap homophobia dalaman lelaki gay bagi sampel ini adalah tinggi iaitu sebanyak 72.7 %. Alasan utama lelaki gay berkahwin adalah untuk mendapatkan zuriat (51.72%), kesedaran merubah identiti seksual (31.03%), desakan keluarga (24.14%) dan damba cinta wanita (24.14%) . Manakala tema utama bagi alasan untuk tidak berkahwin pula adalah tidak yakin melakukan hubungan seks dengan wanita (20.70%), risau terhadap kemampuan mencintai wanita (17.24%), tidak mahu mengecewakan wanita tersebut (10.34%) dan sukar mencari jodoh (10.34%). Sokongan sosial yang padu berupaya mengurangkan diskriminasi serta tahap homofobia yang dialami oleh lelaki gay di Malaysia.

Physiological responses of Avicennia marina var. acutissima and Bruguiera parviflora under simulated rise in sea level

M.Z. Rasheed, O. Normaniza, M.Z. Rozainah

Sains Malaysiana, 2013;42:1059-1064.

Climate change components such as increased in atmospheric carbon dioxide (CO2) and rising sea levels are likely to affect mangrove ecosystems. Healthy mature propagules of A. marina var. acutissima and B. parviflora were subjected to two tidal treatments; shallow and deep; for six months. Shallow treatment mimicked the current tidal fluctuations and deep treatment simulated future tidal conditions under rise in sea level. Deep treatment decreased Amax of both species and significant two way interactions between tidal treatments and species were observed. A400 was significantly reduced in the deep treatment in B. parviflora but not in A. marina. Carbon dioxide compensation point was not affected by the tidal treatments but varied significantly between both species. The ratio A400/Amax was significantly lower in the shallow treatment in B. parviflora indicating higher carbon sink potential at moderate tidal flooding whereas A400/Amax of A. marina was less variable between tidal treatments. Chlorophyll conductance was insensitive to tidal flooding but was significantly higher in B. parviflora than in A. marina. Carbon sequestration of B. parviflora was substantially reduced in the deep treatment while the difference between tidal treatments was much less in A. marina. These results indicated that these two species responded differently under tidal flooding where A. marina was less sensitive to tidal. Thus, A. marina is better adapted to the projected climate change than B. parviflora.

Fulltext Eco-friendly synthesis for MCM-41 nanoporous materials using the non-reacted reagents in mother liquor

Ng EP, Goh JY, Ling TC, Mukti RR

Nanoscale Res Lett, 2013;8(1):120.
PMID: 23497184 DOI: 10.1186/1556-276X-8-120

Nanoporous materials such as Mobil composite material number 41 (MCM-41) are attractive for applications such as catalysis, adsorption, supports, and carriers. Green synthesis of MCM-41 is particularly appealing because the chemical reagents are useful and valuable. We report on the eco-friendly synthesis of MCM-41 nanoporous materials via multi-cycle approach by re-using the non-reacted reagents in supernatant as mother liquor after separating the solid product. This approach was achieved via minimal requirement of chemical compensation where additional fresh reactants were added into the mother liquor followed by pH adjustment after each cycle of synthesis. The solid product of each successive batch was collected and characterized while the non-reacted reagents in supernatant can be recovered and re-used to produce subsequent cycle of MCM-41. The multi-cycle synthesis is demonstrated up to three times in this research. This approach suggests a low cost and eco-friendly synthesis of nanoporous material since less waste is discarded after the product has been collected, and in addition, product yield can be maintained at the high level.

Fulltext Socio-Ecological Hypothesis of Reconciliation: Cultural, Individual, and Situational Variations in Willingness to Accept Apology or Compensation

Komiya A, Ozono H, Watabe M, Miyamoto Y, Ohtsubo Y, Oishi S

Front Psychol, 2020;11:1761.
PMID: 32793075 DOI: 10.3389/fpsyg.2020.01761

The main goal of the present research is to examine socio-ecological hypothesis on apology and compensation. Specifically, we conducted four studies to test the idea that an apology is an effective means to induce reconciliation in a residentially stable community, whereas compensation is an effective means in a residentially mobile community. In Studies 1, 2a, and 2b, American and Japanese participants (national difference in mobility; Study 1) or non-movers and movers (within-nation difference in mobility; Studies 2a and 2b) imagined the situations in which they were hurt by their friends and rated to what extent they would be willing to maintain their friendships upon receipt of apology or compensation. The results showed that compensation was more effective in appeasing residentially mobile people (i.e., Americans and movers) than stable people (i.e., Japanese and non-movers), while apology was slightly more effective appeasing residentially stable people than residentially mobile people (significant in Study 1; not significant in Studies 2a and 2b). In Study 3, by conducting an economics game experiment, we directly tested the hypothesis that mobility would impair the effectiveness of apology and enhance the effectiveness of compensation. The results again partially supported our hypothesis: In the high mobility condition, compensation increased one's willingness to continue the relationship with the offender, when compared to willingness in the low mobility condition. The importance of socio-ecological perspective on the forgiveness literature is discussed.

Malays J Med Sci, 2004 Jan;11(1):86-9.
PMID: 22977365

A case of a 53-year old-single, Kelantanese lady with a diagnosis of paranoid schizophrenia for 28 years is reported with aims to illustrate the influence of life experiences particularly based on education and intelligent on delusion illustrate the evolving nature of the complexity of delusions as well as to show the importance of documentation in psychiatric practice. We concluded that this patient had used defense mechanism of suppression, reaction formation and persecution throughout her delusion. The final persecutory delusion evolved through series of transformation via object of admirations. We postulated that in-depth emotional insight about effects of schizophrenia might have contributed to her self-reflection that have made her frustrated with her poor achievement in life.

Fulltext Fat-Soluble Vitamins and the Current Global Pandemic of COVID-19: Evidence-Based Efficacy from Literature Review

Samad N, Dutta S, Sodunke TE, Fairuz A, Sapkota A, Miftah ZF, et al.

J Inflamm Res, 2021;14:2091-2110.
PMID: 34045883 DOI: 10.2147/JIR.S307333

The outbreak of pneumonia caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), later named COVID-19 by the World Health Organization (WHO), was initiated at Wuhan, Hubei, China, and there was a rapid spread of novel SARS-CoV-2 and the disease COVID-19 in late 2019. The entire world is now experiencing the challenge of COVID-19 infection. However, still very few evidence-based treatment options are available for the prevention and treatment of COVID-19 disease. The present review aims to summarize the publicly available information to give a comprehensive yet balanced scientific overview of all the fat-soluble vitamins concerning their role in SARS-CoV-2 virus infection. The roles of different fat-soluble vitamins and micronutrients in combating SARS-CoV-2 infection have been recently explored in several studies. There are various hypotheses to suggest their use to minimize the severity of COVID-19 infection. These vitamins are pivotal in the maintenance and modulation of innate and cell-mediated, and antibody-mediated immune responses. The data reported in recent literature demonstrate that deficiency in one or more of these vitamins compromises the patients' immune response and makes them more vulnerable to viral infections and perhaps worse disease prognosis. Vitamins A, D, E, and K boost the body's defense mechanism against COVID-19 infection and specifically prevent its complications such as cytokine storm and other inflammatory processes, leading to increased morbidity and mortality overemphasis. However, more detailed randomized double-blind clinical pieces of evidence are required to define the use of these supplements in preventing or reducing the severity of the COVID-19 infection.

PMID: 33916114 DOI: 10.3390/biology10040287

Oxidative stress is a result of disruption in the balance between antioxidants and pro-oxidants in which subsequently impacting on redox signaling, causing cell and tissue damages. It leads to a range of medical conditions including inflammation, skin aging, impaired wound healing, chronic diseases and cancers but these conditions can be managed properly with the aid of antioxidants. This review features various studies to provide an overview on how Carica papaya help counteract oxidative stress via various mechanisms of action closely related to its antioxidant properties and eventually improving the management of various oxidative stress-related health conditions. Carica papaya is a topical plant species discovered to contain high amounts of natural antioxidants that can usually be found in their leaves, fruits and seeds. It contains various chemical compounds demonstrate significant antioxidant properties including caffeic acid, myricetin, rutin, quercetin, α-tocopherol, papain, benzyl isothiocyanate (BiTC), and kaempferol. Therefore, it can counteract pro-oxidants via a number of signaling pathways that either promote the expression of antioxidant enzymes or reduce ROS production. These signaling pathways activate the antioxidant defense mechanisms that protect the body against both intrinsic and extrinsic oxidative stress. To conclude, Carica papaya can be incorporated into medications or supplements to help manage the health conditions driven by oxidative stress and further studies are needed to investigate the potential of its chemical components to manage various chronic diseases.

The relationship between work-life balance, the need for achievement, and intention to leave: Mixed-method study

Dousin O, Collins N, Bartram T, Stanton P

J Adv Nurs, 2021 Mar;77(3):1478-1489.
PMID: 33314305 DOI: 10.1111/jan.14724

AIMS: To examine the mediating role of employee well-being on the relationship between work-life balance practices, the need for achievement and intention to leave among nurses in Malaysia.
BACKGROUND: Work-life balance practices are associated with employee perceptions of the need for achievement and well-being which subsequently influence their intention to leave the organization. This study contributes new knowledge to nursing studies on work-life balance in an Asian and Islamic society where the expectations for women are to focus on family rather than career.
DESIGN: A cross-sectional, explanatory mixed methodology.
METHODS: This is a two-phase study conducted between 2015-2017 with 401 nurses in East Malaysia. In Phase 1, researchers surveyed 379 nurses to test eight hypotheses and in Phase 2 researchers interviewed 22 nurses to explore the results of Phase 1.
RESULTS: Phase 1 revealed job satisfaction mediates the relationship between work-life balance practices (e.g. flexibility and choice in working hours, supportive supervision), financial success, and intention to leave. However, life satisfaction and money as a motivator did not mediate such relationships. Phase 2 identified four important factors that cast light on survey results: working conditions of Malaysian nurses; inadequate compensation in the public healthcare sector; team-based practices; and pressure on senior nurses in both administrative and clinical roles.
CONCLUSION: This is one of the first studies to investigate work-life balance issues among nurses in Malaysia. Outcomes of this study extend the debates on work-life balance and employee well-being in an Asian Islamic social context.
IMPACT: The use of flexible working arrangements and collectivist teamwork approaches, improving compensation and employment benefits and eliminating the 'time-based job promotion' policy may help to mitigate work-life balance issues and intention to leave among nurses in Malaysia.
