    The study of cohesive sediment in the laboratory gives rise to a number of instrumentation problems, especially in the location of mud bed, fluid mud and hindered settling layers and in the measurement of flow velocities. This paper describes the application of medical diagnostic ultrasound technique in the cohesive sediment study conducted at the University of Liverpool, United Kingdom. This paper illustrates that the use of ultrasound technique creates a reasonably flexible environment for the study of fluid mud phenomenon in which bed formation and flow velocities can be measured easily, accurately and non-intrusively. This in turn will assist in development of computer models to predict the environmental impact, siltation rates and dredging requirements in both new and existing ports and harbour developments.

    Objective: This study aims to evaluate the association of neurotic personality traits and coping styles with depression amongst first year medical and dental students. Methods: A total of 167 students consisting of 133 medical and 34 dental students in their first year were recruited. All the subjects were assessed using BDI, NEO PI-R (N) and Brief COPE for depression, neurotic personality traits and coping styles respectively. Result: First year dental students were 3 times more likely to have depression than first year medical students. Students who scored high and very high on the total Neuroticism factor and the Depression facet of NEO PI-R (N) were 3.6 times and 7 times more likely to have depression than students who scored very low, low or average for the above scales. All coping styles and other socio-demographic factors showed no association with depression. Conclusion: Neurotic personality traits are significantly associated with depression. NEO PI-R (N) proved to be a useful tool to evaluate the neurotic traits among medical and dental students allowing early interventional measures to those who need it.

    Malaysia mempunyai tanggungjawab mendepositkan koordinat-koordinat titik-titik pangkal yang digunakan untuk mengukur lebar batas laut wilayah dan sempadan zon-zon maritim yang lain kepada Setiausaha Agung, Pertubuhan Bangsa-Bangsa Bersatu (PBB). Titik-titik pangkal adalah asas kepada penetapan bagi zon-zon maritim, perundangan batas maritim dan perlaksanaan penguatkuasaan. Kertas ini menghuraikan bagaimana dua parameter penting iaitu kecerunan pesisir depan dan datum carta boleh menyebabkan ketidakpastian terhadap posisi titik-titik pangkal. Hubungkait trigonometri antara parameter membuktikan sisihan datum sebanyak 0.2 m dan kecerunan pesisir depan sebanyak 0.1º menyebabkan ketidakpastian posisi mendatar sebanyak 114.6 m. Ketidakpastian kedudukan titik pangkal menjadi signifikan apabila sisihan antara datum carta meningkat dan kecerunan pesisir depan semakin landai. Hasil prosesan kedudukan titik-titik pangkal melalui perisian “CARIS” mendapati perbezaan kedudukan titik-titik pangkal sebanyak 108 m, 169 m dan 107 m. Kesimpulannya, ketidakpastian ini boleh menyebabkan negara kerugian kawasan maritim.

    Malaysia has a long coastline stretching over 4,809 km where more than 1,300 km of beaches are experiencing erosion.
    Coastal erosion is recognised as the permanent loss of land and habitats along the shoreline resulting in the changes
    of the coast. Thus, it is important to detect and monitor shoreline changes especially in Pahang coast by identifying the
    rate of shoreline erosion and accretion. This study used temporal data and high spatial resolution imagery (SPOT 5) using
    remote sensing and GIS techniques to monitor shoreline changes along 10 study locations, which is from Cherating to
    Pekan of the Pahang coast. The total length of shoreline changes is about 14 km (14035.10 m) where all these areas are
    very likely to experience erosion ranging from 0.1 to 94.7 ha. On the other hand, these coastal areas found a minimal
    accretion with increased sediment from 0.1 to 2.8 ha. Overall, the coastal areas are exposed to higher erosion process
    than accretion with a very high vulnerability of erosion rate from 1.8 to 20.9 meter per year. The findings on monitoring
    shoreline changes and identifying vulnerable erosion areas might be useful in the policy and decision making for
    sustainable coastal management.

    A review of the criminological literature indicates that some personality traits appear to develop and shape violent criminal behaviour. With this in mind, the present study was aimed to examine the personality profiles of Malaysian male murderers utilising the Alternative Five Factor Model (AFFM) constituting five personality traits: Activity, Sociability, Aggressiveness-Hostility, Impulsive Sensation Seeking, and Neuroticism- Anxiety. Methods: The present study was an observational cross-sectional study using a guided self-administered questionnaire. Items representing the five personality traits were assessed through the Malay version of Zuckerman-Kuhlman Personality Questionnaire-40-Cross Cultural Questionnaire (ZKPQ-M-40-CC). 71 male prisoners convicted of murder who are incarcerated in 11 Malaysian prisons were recruited. Descriptive item analyses were carried out to elicit the level of responses for each item in the ZKPQ-M-40-CC. Furthermore, the descriptive personality profiles using mean scores were performed. Results: The results indicated that the mean score of Activity (29.35, SD = 5.66) was higher than other personality traits. The mean score of Impulsive Sensation Seeking (21.65, SD = 6.48) and Aggressiveness-Hostility (21.65, SD = 6.48) were higher than the mean score of Neuroticism-Anxiety (17.96, SD = 5.51). Among the participants, 56.3% of them scored above the mean score (M = 26.54) for Sociability personality traits, which was the highest compared to other personality traits. 53.5% of the murderers scored equal or above the mean score (M = 6.48). Correlations among the five personality traits indicated several significant associations. Conclusion: In conclusion, the present study successfully identified the personality profiles of Malaysian male prisoners convicted of murder.

    This study investigates the influence of accounting conservatism on corporate innovation investment through the lens of information asymmetry theory. While existing literature acknowledges the importance of accounting conservatism in corporate decision-making, there remains a gap in understanding how it specifically affects innovation investment, particularly in varied market environments and regulatory contexts. Specifically, current research often overlooks the heterogeneity of the impact of accounting conservatism on innovation investment under different market environments and regulatory frameworks. Additionally, there is a lack of specialized studies on the unique group of Chinese listed companies. This study fills this gap by empirically analyzing data from Chinese A-share listed companies, revealing a negative correlation between accounting conservatism and corporate innovation investment. Through empirical analysis of the financial reports and research and development (R&D) investment data of Chinese A-share listed companies from 2015 to 2022, this study finds a significant negative correlation between accounting conservatism and corporate innovation investment. Specifically, as accounting conservatism increases, corporate investment in R&D shows a decreasing trend, with a correlation coefficient of -0.364. This result is further validated by hierarchical regression analysis, where the regression coefficient is -0.465, indicating that accounting conservatism has a significant inhibitory effect on corporate innovation investment. This study is pioneering in its examination of the relationship between accounting conservatism and corporate innovation investment within the unique market environment of China, taking into account its distinctive characteristics and rapidly evolving technological industry background. To quantify accounting conservatism, the research employs the C-Score and G-Score models, while employing a range of indicators to measure corporate innovation investment, including proportions of R&D expenditure, number of new products or services, patent applications, total R&D personnel, capital investments, and progress in innovation projects. This comprehensive evaluation method enhances the accuracy and reliability of the study. The contribution of this study is significant as it offers a fresh perspective on how accounting conservatism influences corporate innovation investment. By providing empirical data support, it assists investors and corporate managers in making informed financial decisions and shaping innovation strategies. Through hierarchical regression analysis, the study substantiates the detrimental impact of accounting conservatism on corporate innovation investment, thereby establishing new theoretical and practical foundations for further research and application in related fields.

    Protein solubility is a critical prerequisite to any proteomics analysis. Combination of urea/thiourea and 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS) have been routinely used to enhance protein solubilization for oil palm proteomics studies in recent years. The goals of these proteomics analysis are essentially to complement the knowledge regarding the regulation networks and mechanisms of the oil palm fatty acid biosynthesis. Through omics integration, the information is able to build a regulatory model to support efforts in improving the economic value and sustainability of palm oil in the global oil and vegetable market. Our study evaluated the utilization of sodium deoxycholate as an alternative solubilization buffer/additive to urea/thiourea and CHAPS. Efficiency of urea/thiourea/CHAPS, urea/CHAPS, urea/sodium deoxycholate and sodium deoxycholate buffers in solubilizing the oil palm (Elaeis guineensis var. Tenera) mesocarp proteins were compared. Based on the protein yields and electrophoretic profile, combination of urea/thiourea/CHAPS were shown to remain a better solubilization buffer and additive, but the differences with sodium deoxycholate buffer was insignificant. A deeper mass spectrometric and statistical analyses on the identified proteins and peptides from all the evaluated solubilization buffers revealed that sodium deoxycholate had increased the number of identified proteins from oil palm mesocarps, enriched their gene ontologies and reduced the number of carbamylated lysine residues by more than 67.0%, compared to urea/thiourea/CHAPS buffer. Although only 62.0% of the total identified proteins were shared between the urea/thiourea/CHAPS and sodium deoxycholate buffers, the importance of the remaining 38.0% proteins depends on the applications. The only observed limitations to the application of sodium deoxycholate in protein solubilization were the interference with protein quantitation and but it could be easily rectified through a 4-fold dilution. All the proteomics data are available via ProteomeXchange with identifier PXD013255. In conclusion, sodium deoxycholate is applicable in the solubilization of proteins extracted from oil palm mesocarps with higher efficiency compared to urea/thiourea/CHAPS buffer. The sodium deoxycholate buffer is more favorable for proteomics analysis due to its proven advantages over urea/thiourea/CHAPS buffer.

    Proteomics technologies were first applied in the oil palm research back in 2008. Since proteins are the gene products that are directly correspond to phenotypic traits, proteomic tools hold a strong advantage above other molecular tools to comprehend the biological and molecular mechanisms in the oil palm system. These emerging technologies have been used as non-overlapping tools to link genome-wide transcriptomics and metabolomics-based studies to enhance the oil palm yield and quality through sustainable plant breeding. Many efforts have also been made using the proteomics technologies to address the oil palm's Ganoderma disease; the cause and management. At present, the high-throughput screening technologies are being applied to identify potential biomarkers involved in metabolism and cellular development through determination of protein expression changes that correlate with oil production and disease. This review highlights key elements in proteomics pipeline, challenges and some examples of their implementations in plant studies in the context of oil palm in particular. We foresee that the proteomics technologies will play more significant role to address diverse issues related to the oil palm in the effort to improve the oil crop.

    Baccaurea pubera is a blood red coloured fruit found exclusively in Borneo. This study was conducted to evaluate the effect of superheated steam treatment on its antioxidant properties and mineral content as well as to determine nutritional values of the fruit. The fruits were treated with superheated steam at 170 °C for 15 min prior to extraction and freeze drying. The results showed that, in comparison to the control, superheated steam treatment enhanced the total phenolic content by 147.8% (287.16 mg GAE/100 g vs. 115.87 mg GAE/100 g) and DPPH radical scavenging activity by 23.7% (66.94% vs. 54.13%). However, there were reductions, as compared to the control treatments, in total flavonoid content by 16.5% (8.29 mg QE/100 g vs. 9.93 mg QE/100 g), lycopene content by 28.6% (0.020 μg/100 g vs. 0.028 μg/100 g) and ferric reducing antioxidant power by 22.2% (844.41 mg TE/100 g vs. 1085.15 mg TE/100 g). The superheated steam treatment was also observed to reduce the mineral content of the fruit, from as little as 3.6% to as high as 52% depending upon the specific mineral.

    Objective: This study aimed to assess the effectiveness of a psycho-education intervention programme in improving the coping strategies of Jordanian breast cancer patients.

    Methods: A double-blinded randomised control trial involving 200 participants between the ages of 20 to 65 years old breast cancer patients was performed. Apart from those who refused participation, patients with chronic diseases and extreme baseline depression scores were also excluded. The control group received standard care twice a week from the social welfare services team facilitator compared to the intervention group that received additional psycho-education intervention programme (PEIP). The coping strategies were measured using the Brief-COPE inventory consisting of 28 items. It was administered on the second and 12th week of trial. The primary end point was compared between pre- and post-intervention. The effect of the intervention between groups, time, and covariates was measured using the generalised linear mixed model (GLMM) analysis.

    Results: The mean (SD) of adaptive coping score among the intervention group increased from 5.63 (1.3) at baseline to 6.42 (1.3) at post-intervention. The mean avoidant coping score was 3.87 (1.1) at baseline but reduced to 3.69 (0.8) post-intervention. GLMM showed that women who received the intervention reported significantly higher usage of the adaptive coping strategies after attending the programme (B=0.921, p <0.001).

    Conclusion: PEIP significantly improved knowledge of breast cancer patients. Thus, this programme may be considered as a part of the healthcare services in Jordan towards improving the adaptive coping strategies among breast cancer patients, which may point towards the potential for these services to increase adaptive coping strategies among patients in Jordan.

    Implications for Public Health: PEIP may be considered as psychosocial intervention in public health and healthcare setting to address rising concerns on quality of care among breast cancer patients.

    Proteome data was obtained from the fruit mesocarps of the two oil palm species, namely, the African Elaeis guineensis (commercial tenera or commonly known as D x P and MPOB-Nigerian tenera) and the South American Elaeis oleifera. Total proteins were extracted from randomly selected fruitlets and subjected to proteomics characterisation by means of liquid chromatography mass spectrometry. Number of proteins identified, the grouping of the biological replicates from five developmental weeks after anthesis, and the localisation of gene corresponded to the detected proteins on the oil palm chromosomes, were presented. A total of 4,116, 4,210 and 4,081 proteins were found in commercial tenera and MPOB Nigerian tenera for Elaeis guineensis; and Elaeis oleifera, respectively. Principal component analysis showed two distinct clusters that corresponded to Elaeis guineensis and Elaeis oleifera. Collectively, genes that corresponded to the identified proteins were found to be located in all 16 oil palm chromosomes. A total of 59 proteins from Elaeis guineensis and Elaeis oleifera were down-regulated for >5-fold change during the peak of lipid biosynthesis compared to the onset. The same comparative analysis revealed that 66 proteins were up-regulated for >5-fold change. About 60.0% of the observed proteins were involved in catalytic activity while 28.5% were associated with redox reaction. Based on same datasets, the tricarboxylic acid cycle and 5-hydroxytryptamine degradation pathways were found to be enriched the most (>36-fold change). These data can be used to support the oil palm gene model validation and lipid metabolism research, particularly in the areas of oil yield and quality. The tabulated protein lists of identified proteins and their expression changes from these varieties were provided as supplementary files. Raw MSF and mzid files for all the oil palm species were deposited in the ProteomeXchange (PXD017436).

    INTRODUCTION: The study was performed to determine the psychological problems in children with idiopathic nephrotic syndrome (INS) while they were on steroid therapy, as compared to healthy children.

    METHODS: This prospective cohort study was conducted in a paediatric clinic of a tertiary hospital. Parents of the participants in the INS group and control group (comprising children without chronic illness) completed questionnaires using the Child Behavioural Checklist (CBCL). The CBCL measures a range of age-specific emotional and psychological problems, including internalising and externalising domains. Analyses of the CBCL scores between groups were done using Mann-Whitney U test.

    RESULTS: A total of 140 children were recruited with an equal number in the INS and control groups. There was a significant difference in the mean total CBCL scores between the INS group and the control group, specifically in the withdrawal, somatic, anxious and aggressiveness subdomains. Similar findings were demonstrated in correlation between total psychological problems and corticosteroid dosage. In the INS group, steroid dose and cushingoid features were found to have a significant positive association with internalising psychological problems.

    CONCLUSION: Children with INS on corticosteroid treatment showed an increase in internalising and externalising scores, as compared to healthy children.

    BACKGROUND: In the context of the coronavirus (COVID-19) pandemic, effectively coping with daily stressors is crucial for children who experience restrictions on physical movement and social activities. We examined the effects of the online-delivered guided imagery relaxation (GIR) technique on the stress and well-being of primary school children.

    METHODS: Thirty-four (N = 34) 11-year-old students were randomly assigned to either intervention (n = 17) or waitlist-control (n = 17) groups. The participants from the intervention group were required to attend a 4-week online GIR session and practice the techniques daily for 5 min-10 min. The Stress in Children (SiC) questionnaire, the Strengths and Difficulties Questionnaire-Parent Reported (SDQ-PR) and tracking form were administered pre- and post-intervention.

    RESULTS: Eleven (64.7%) participants attended all sessions and eight (47.0%) completed daily practices. Mixed-model ANOVA indicated no significant difference between participants from intervention and waitlist-control groups across pre- and post-intervention time points, with P-values greater than 0.05 for stress and well-being.

    CONCLUSION: Issues regarding online intervention, including managing children's activities from a distance, Internet connectivity, and time limitations might have affected their adherence and the research outcome. Nonetheless, the online-delivered GIR technique is a promising intervention modality. However, its implementation should be improvised to be more impactful.

    Global warming has led to sea levels raise (SLRs) and Malaysia is no exception to this problem. Especially for low-lying coastal areas including the Kuala Kedah area which is active in agricultural and fisheries activities. Farmers have had to bear up to 75 % of yield losses due to seawater breaches since 2016. Therefore, this study is designed to assess the impact of seawater encroachment on water quality through spatial technology approaches and hydrodynamic modeling related to the growth of paddy trees. The study was conducted during two different paddy cultivation seasons namely Season 1-2019 and Season 2-2019 which take place in the southwest and northeast monsoon in Kuala Kedah, Malaysia. The study involved three phases, which are the assessment of salinity and pH concentration levels, the assessment of the health of paddy crops through multispectral image analysis involving three plant indices (VI), namely Normalized Difference Vegetation Index (NDVI), Blue Normalized Difference Vegetation Index (BNDVI) and Normalized Difference Red Edge (NDRE), and finally, the assessment of the impact of SLR through the numerical method in MIKE 21 for hydrodynamic modeling considering two conditions that are without mitigation factor (K1) and with existing mitigating factor (K2). According to the findings, the salinity concentration trend is decreasing across the growth stage during Season 1-2019, whereas it is the contrary during Season 2-2019. It was discovered that during the study period for both tidal events, 73 % of the 44 sampling points in Season 1-2019, as opposed to just 3 % in Season 2-2019, were categorized as Class 4 and Class 5. Even though there were fluctuations throughout the observation, the pH reading is still within the allowed range of 6.5 to 9.0 for the estuary area. Following that, the ANOVA analysis proved that salinity concentration a statistically significant difference with tidal variations and pH levels. Moreover, the multispectral image analysis findings revealed that the VI value was correlated with both the yield and the health of the rice crop, with R-square values of 0.842 compared to 0.706 and 0.575 for NDVI and BNDVI values, respectively. It confirmed that NDRE granted a more accurate and reliable measurements. Additionally, the hydrodynamic simulation results demonstrated that, if the mitigation factors were considered in the modeling, overflow seawater to the mainland could be reduced by up to 20 %, reducing the impact of coastal flooding on the local area as well as the nearby rice cultivation area. Ultimately, these three elements-water quality, vegetation index, and hydrodynamic modeling-can assist in identifying the underlying cause of the problem and develop short and long-term solutions.

    Chitinases are glycosyl hydrolases that cleave the β-1,4-glycosidic linkages between N-acetylglucosamine residues in chitin which is a major component of fungal cell wall. Plant chitinases hydrolyze fungal chitin to chitin oligosaccharides that serve as elicitors of plant defense system against fungal pathogens. However, plants synthesize many chitinase isozymes and some of them are not pathogenesis-related. In this study, three full-length cDNA sequences encoding a putative chitinase (EgChit3-1) and two chitinase-like proteins (EgChit1-1 and EgChit5-1) have been cloned from oil palm (Elaeis guineensis) by polymerase chain reaction (PCR). The abundance of these transcripts in the roots and leaves of oil palm seedlings treated with Ganoderma boninense (a fungal pathogen) or Trichoderma harzianum (an avirulent symbiont), and a combination of both fungi at 3, 6 and 12 weeks post infection were profiled by real time quantitative reverse-transcription (qRT)-PCR. Our findings showed that the gene expression of EgChit3-1 increased significantly in the roots of oil palm seedlings treated with either G. boninense or T. harzianum and a combination of both; whereas the gene expression of EgChit1-1 in the treated roots of oil palm seedlings was not significantly higher compared to those of the untreated oil palm roots. The gene expression of EgChit5-1 was only higher in the roots of oil palm seedlings treated with T. harzianum compared to those of the untreated oil palm roots. In addition, the gene expression of EgChit1-1 and EgChit3-1 showed a significantly higher gene expression in the leaf samples of oil palm seedlings treated with either G. boninense or T. harzianum.
