On the estimation of three parameters lognormal distribution based on fuzzy life time data

Shafiq M, Alamgir, Atif M

Sains Malaysiana, 2016;45:1773-1777.

Countless statistical tools are available to extract information from data. Life time modeling is considered as one of
the most prominent fields of statistics, which is evident from the developments made in this field in the last few decades.
Almost every statistic for life time analysis is based on precise life time observations, however, life time is not a precise
measurement but more or less fuzzy. Therefore, in addition to classical statistical tools, fuzzy number approaches to
describe life time data are more suitable. In order to incorporate fuzziness of the observations, fuzzy estimators for the
three parameter lognormal distribution were suggested. The proposed estimators cover stochastic variation as well as
fuzziness of the observations.

For patients with pyogenic spondylodiscitis, medical therapy with antibiotics is the first line of treatment. Response to antibiotics can be assessed by improvement of symptoms, reduction in inflammatory markers, and radiological evidence of infection resolution with magnetic resonance imaging (MRI). We report a case of a 60-year-old man who presented with intermittent fever and persistent back pain. He was initially treated with an intravenous antibiotic for sepsis secondary to Salmonella enteritidis bacteremia. His spine MRI showed compression of the T10 vertebra with vertebral abnormality suggestive of metastases. He showed no clinical improvement after a course of intravenous antibiotics. Following that, debridement and spinal instrumentation of the thoracic vertebra were done in single-stage surgery.

Maazullah Khan, Abdurab, Muhammad Hanif, Mansoor Khan Khattak, Muhammad Ramzan

Sains Malaysiana, 2018;47:1061-1067.

Air heating by solar collectors is renewable technology providing hot air for different purposes. The present research
emphasizes on analysis of energy, exergy and efficiency of a flat plate solar air heater. The analysis model was tested
on five different air mass flow rates of 0.5 (Natural), 1.31, 2.11, 2.72 and 3.03 kgs-1 under three different tilt angles of
25, 35 (Recommended) and 50o
. The data was replicated three times making a total of 45 treatments. A two factorial
completely randomized design was used to find if there is any significant difference among the treatments. The results
showed that the solar collector gave better performance at air mass flow of 3.03 kgs-1 under tilt of 35o
. At maximum
air mass flow rate of 3.03 kgs-1and optimum tilt angle of 35o
the maximum energetic efficiency of 51%, while minimum
exergetic efficiency of 24% and maximum overall efficiency of 71% were recorded. It was concluded that to get maximum
thermal efficiencies of 71% from flat plate solar collector used as an air heater must be operated at high air mass flow
rates of 3.03 kgs-1under 35o
tilt angle at Peshawar, Pakistan.

This case series reports four patients who used religion and spirituality to relieve symptoms of post traumatic stress disorder (PTSD) following motor vehicle accidents. Their symptoms subsided after a few weeks and the recovery is sustained after one month. This demonstrates that in a country where psychological help is still scarce and religion is central to its culture, intervention based on spirituality and religion can be used as an alternative early intervention to relieve symptoms of PTSD and hence protects them from developing the condition.

Central obesity reduction through effective treatment is desirable everywhere in the world including Pakistan. The current study intends to provide effective intervention programs to reduce central obesity among Pakistani women. Through randomized control trial study fourteen females (N= 14, WHR= .897 ± .030) were recruited by employing penal data technique with simple randomization. The sample distributed into two equal groups from online randomization. The experimental group received 10-week sessions of modified cognitive behavior therapy (CBT) along with supervised and unsupervised exercise execution, plus supervised diet management plan. As a contrast, the control group received 10-week sessions without offering standard treatment. The results found that the intervention group or experimental group significantly reduced waist circumference (-2.33 inches) while control group reduced (-0.36 inches) within 10 weeks, F=42.82, p

Shehzad MA, Maqsood M, Abbas T, Ahmad N

Sains Malaysiana, 2016;45:1497-1507.

Boron (B) is a mineral considered essential for improving sunflower (Helianthus annuus L.) resistance to drought. B supplements (0, 15-, 30- and 45 mg L-1) under well-watered and variable water deficit levels (64 and 53 mm irrigation depths) were evaluated for their effects on growth, oil quality and water use efficiency (WUE) in a field study for two consecutive years (i.e. 2011 and 2012). The duration of 50% inflorescence emergence, 50% flowering and 50% maturity stages were reduced with increasing moisture stress. All B application rates improved sunflower growth compared to no B control treatment. The moisture deficit treatments of 64 and 53 mm irrigation depths significantly (p<0.05) reduced the yield-related components. Achenes/head, achenes weight and achene yield under water stress conditions were considerably improved by foliar application of B at 30 mg L-1. An increase in protein contents and a decrease in oil contents were observed with B foliar application under moisture deficit treatments. Foliar application of B (30 mg L-1) on water stressed plants also resulted in increased WUE. The highest net benefits were achieved with B concentration of 30 mg L-1 under well-watered and mild deficit water level of 64 mm irrigation depth. The highest application rate of B (45 mg L-1) gave the best results at the most severe water deficit level. In conclusion, the B rates of 30 and 41 mg L-1 performed best for improving drought tolerance in terms of higher sunflower productivity under mild and higher water deficit conditions

Introduction: Posttraumatic stress disorder (PTSD) commonly occur following exposure to traumatic events. Since its formal introduction into the Diagnostic and Statistical Manual of Mental Disorders 3rd Edition (DSM-III) in 1980, it has seen a few changes to its criteria. Currently in DSM-5, major changes was made and tools such as the PTSD Checklist for DSM-5 (PCL-5) were developed to reflect those changes. Tools to screen and diagnose PTSD is invalu- able to properly manage the condition, but to date no measure, in keeping with the DSM-5, has been produced for the Malaysian population. The objective was to translate the PCL-5 into Malay and validate it for use in the Malaysian population. Methods: The PCL-5 was translated according to guidelines. A convenient sample of subject were re- cruited from those attending the Orthopaedic Ward and Outpatient Departments due to injuries from motor vehicle accidents (MVA). Subjects completed the Malay PCL-5 (MPCL-5) on the day of recruitment and were then inter- viewed using the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). Two weeks later they were followed-up to again complete the MPCL-5. Results: 204 subjects participated in the study. The MPCL-5 was found to have good face, content and construct validity. It also demonstrated strong internal consistency (Cronbach’s Alpha = .89) and inter-rater reliability (r = .81). Conclusion: The MPCL-5 is a valid and reliable measure for PTSD to be used in the Malaysian population.

BACKGROUND: An outbreak of global pandemic COVID-19 profoundly affects life around the globe. Prolonged isolation, contact restriction and economic shutdown impose a deeply change to the psychosocial environment. These indicate a tendency to threaten the mental health of adolescents' significantly. Detecting adolescents' psychosocial risk during Pandemic COVID-19, particularly when they stay at home, may be helpful to better understand their mental health well- being.

AIMS: The current study aimed to explore psychosocial risk factors associated with mental health of adolescents' in the midst of the outbreak.

METHOD: This research uses a qualitative approach which focuses on focus group discussions interviews. This research took 6 weeks via online communication platform involving (n = 15) adolescents from the Low Income Household.

RESULT: The participants adolescents' psychosocial risk experience during amidst of Outbreak Covid-19 Pandemic are composed of (1) self- conflict (develop negative thought at home, unplanned of daily activities, changing sleep pattern and irregular wake up time and massively use internet) (2) Family Members (Conflict between parent and miscommunication between siblings) (3) School (Piling up on homework, Inadequate guidance for homework and Inability to comprehend online learning). These psychosocial risk factors have caused disruption to daily life adolescents' during outbreaks and almost inevitably trigger a spike in mental health issues.

CONCLUSION: Overall of study emphasized that psychosocial risks are important factors that can be addressed in order to reduce mental health problem.

Fulltext Role of translaminar pressure gradient differences in glaucoma - a review

Jemaima, C.H., Muhammad Syamil, M.S.

Medicine & Health, 2018;13(1):3-11.

MyJurnal

Glaucoma is a group of diseases which result in a progressive loss of retinal ganglion cells, producing characteristic optic nerve head appearance with corresponding visual loss. The aetiology remains unclear until today. Previous authors had tried to associate its pathology in relation to intracranial pressure level. We review the literature on interrelation of intraocular pressure (IOP) and intracranial pressure (ICP) which gives rise to the study of translaminar pressure gradient (TLPG) in postulating its causal factor towards glaucoma. Several studies had demonstrated that ICP was reduced in patients with glaucoma, and in sequence with normal or raised IOP, leads to increased level of TLPG. The increased TLPG which acts across the lamina cribrosa may cause a posteriorly bowed lamina cribrosa, therefore leading to glaucomatous changes. This review also explores the current available methods in
measuring ICP accurately. Further studies are needed to elucidate possible disease mechanism in keeping with IOP-ICP relationship, thus confirming the findings of
previous authors.

Fulltext A review on development of blood substitute

Mislia Othman, Muhammad Azrul Zabidi

Jurnal Sains Kesihatan Malaysia, 2020;18(2):59-71.

MyJurnal

This review paper aims to present an overview of the development of blood substitute particularly red blood cell substitute or artificial oxygen carrier. Knowledge on human blood inspired from the understanding of human blood circulation system. Ibn Nafis was first to describe that blood flow through respiratory system before entering the heart. This finding denied the claim that tiny pores present within the septum of the heart. Then, William Harvey further described human cardiovascular system in detail and contributed to better understanding on the roles of blood in body. Several blood transfusions were attempted using blood collected from human, animal and other blood substitutes such as milk before the practice was banned for almost 150 years in Europe. Major discoveries on blood group and antibody reaction have made blood transfusion safer. However, several issues and challenges have re-triggered the exploration to develop red cell substitutes. Two approaches have been taken to develop the red blood cell substitute which are classified into biological and chemical based oxygen carriers. The earliest efforts have been on haemoglobin based oxygen carrier (HBOC) and perfluorocarbon (PFC) while the recent developement are on polymer-based oxygen carrier and in-vitro stem cell derived red blood cell.
