    PMID: 12466626
    The title molecule, C(13)H(13)N(3)O(3).H(2)O, is in the form of a monohydrated zwitterion. The tetrahydropyridinium ring adopts an envelope conformation and is nearly coplanar with the plane of the imidazoline ring. The water solvate molecule plays an important role as a bridge between zwitterions, forming molecular chains running along the c direction, which are interconnected by N-H.O hydrogen bonds into molecular ribbons. The crystal packing is further stabilized by another N-H.O and one O-H.N hydrogen bond, which interconnect the molecular ribbons.

  2. Fulltext A Longitudinal Analysis of Daily Pill Burden and Likelihood of Optimal Adherence to Antiretroviral Therapy Among People Living With HIV Who Use Drugs
    Mohd Salleh NA, Richardson L, Kerr T, Shoveller J, Montaner J, Kamarulzaman A, et al.
    J Addict Med, 2018 3 10;12(4):308-314.
    PMID: 29521670 DOI: 10.1097/ADM.0000000000000403
    OBJECTIVES: Among people living with HIV (PLWH), high levels of adherence to prescribed antiretroviral therapy (ART) is required to achieve optimal treatment outcomes. However, little is known about the effects of daily pill burden on adherence amongst PLWH who use drugs. We sought to investigate the association between daily pill burden and adherence to ART among members of this key population in Vancouver, Canada.

    METHODS: We used data from the AIDS Care Cohort to Evaluate Exposure to Survival Services study, a long-running community-recruited cohort of PLWH who use illicit drugs linked to comprehensive HIV clinical records. The longitudinal relationship between daily pill burden and the odds of ≥95% adherence to ART among ART-exposed individuals was analyzed using multivariable generalized linear mixed-effects modeling, adjusting for sociodemographic, behavioural, and structural factors linked to adherence.

    RESULTS: Between December 2005 and May 2014, the study enrolled 770 ART-exposed participants, including 257 (34%) women, with a median age of 43 years. At baseline, 437 (56.7%) participants achieved ≥95% adherence in the previous 180 days. Among all interview periods, the median adherence was 100% (interquartile range 71%-100%). In a multivariable model, a greater number of pills per day was negatively associated with ≥95% adherence (adjusted odds ratio [AOR] 0.87 per pill, 95% confidence interval [CI] 0.84-0.91). Further analysis showed that once-a-day ART regimens were positively associated with optimal adherence (AOR 1.39, 95% CI 1.07-1.80).

    CONCLUSIONS: In conclusion, simpler dosing demands (ie, fewer pills and once-a-day single tablet regimens) promoted optimal adherence among PLWH who use drugs. Our findings highlight the need for simpler dosing to be encouraged explicitly for PWUD with multiple adherence barriers.

    Gelatin is a very popular pharmaceutical and food ingredient and the most studied ingredient in Halal researches. Interest in source gelatin authentication is based on religious and cultural beliefs, food fraud prevention and health issues. Seven gelatin authentication methods that have been developed include: nucleic acid based, immunochemical, electrophoretic analysis, spectroscopic, mass-spectrometric, chromatographic-chemometric and chemisorption methods. These methods are time consuming, and require capital intensive equipment with huge running cost. Reliability of gelatin authentication methods is challenged mostly by transformation of gelatin during processing and close similarities among gelatin structures. This review concisely presents findings and challenges in this research area and suggests needs for more researches on development of rapid authentication method and process-transformed gelatins.

    ntroduction: In the marking of objective structured clinical examination (OSCE), checklist scoring and global rating are two commonly used scoring systems. Objective: The purpose of this study was to examine correlations between checklist scores and global ratings for four OSCE stations of different station type. Method: Data for this study was obtained from the Final Year OSCE (n=185). Each station’s score sheet consisted of a detailed checklist of items examined. A global rating scale was also included for the examiner to indicate the global assessment for the station. Spearman’s rho correlation coefficients between checklist scores and global ratings were computed for four stations of different station type. For each station, correlations between checklist scores and global ratings were also checked across the three parallel circuits running concurrently and throughout the four rounds. Result: Spearman’s rho correlation coefficients (ρ) between checklist scores and global ratings for the four stations ranged between 0.62 to 0.88, at p

    Willmott AGB, James CA, Bliss A, Leftwich RA, Maxwell NS
    J Biomech, 2019 01 23;83:324-328.
    PMID: 30563764 DOI: 10.1016/j.jbiomech.2018.11.044
    The comparability and reliability of global positioning system (GPS) devices during running protocols associated with team-sports was investigated. Fourteen moderately-trained males completed 690 m of straight-line movements, a 570 m change of direction (COD) course and a 642.5 m team-sport simulated circuit (TSSC); on two occasions. Participants wore a FieldWiz GPS device and a Catapult MinimaxX S4 10-Hz GPS device. Typical error of measurement (TE) and coefficient of variation (CV%) were calculated between GPS devices, for the variables of total distance and peak speed. Reliability comparisons were made within FieldWiz GPS devices, between sessions. Small TE were observed between FieldWiz and Catapult GPS devices for total distance and peak speed during straight-line (16.9 m [2%], 1.2 km·h-1 [4%]), COD (31.8 m [6%], 0.4 km·h-1 [2%]) and TSSC protocols (12.9 m [2%], 0.5 km·h-1 [2%]), respectively, with no significant mean bias (p > 0.05). Small TE were also observed for the FieldWiz GPS device between sessions (p > 0.05) for straight-line (9.6 m [1%], 0.2 km·h-1 [1%]), COD (12.8 m [2%], 0.2 km·h-1 [1%]) and TSSC protocols (6.9 m [1%], 0.6 km·h-1 [2%]), respectively. Data from the FieldWiz GPS device appears comparable to established devices and reliable across a range of movement patterns associated with team-sports.

    Zhang G, Jing W, Tao H, Rahman MA, Salih SQ, Al-Saffar A, et al.
    Work, 2021;68(3):935-943.
    PMID: 33612535 DOI: 10.3233/WOR-203427
    BACKGROUND: Human-Robot Interaction (HRI) has become a prominent solution to improve the robustness of real-time service provisioning through assisted functions for day-to-day activities. The application of the robotic system in security services helps to improve the precision of event detection and environmental monitoring with ease.

    OBJECTIVES: This paper discusses activity detection and analysis (ADA) using security robots in workplaces. The application scenario of this method relies on processing image and sensor data for event and activity detection. The events that are detected are classified for its abnormality based on the analysis performed using the sensor and image data operated using a convolution neural network. This method aims to improve the accuracy of detection by mitigating the deviations that are classified in different levels of the convolution process.

    RESULTS: The differences are identified based on independent data correlation and information processing. The performance of the proposed method is verified for the three human activities, such as standing, walking, and running, as detected using the images and sensor dataset.

    CONCLUSION: The results are compared with the existing method for metrics accuracy, classification time, and recall.

    The incidence of varicose veins and the need for treatment has shown a tremendous increase over the years. Debilitating venous ulcers and dragging edemas of the lower limb with overall improvement in cosmetic results and availability of endovenous procedures has brought many patients forward for treatment. Continuous-wave handheld Doppler usage is limited by its diagnostic capabilities, thus the need to determine its real effectiveness. Benefits of using hand-held dopplers lies in its rapidity in assessment of patients, it's low running cost and short learning curve. This is important as duplex ultrasounds are not readily available in district hospitals. This study aims to determine the clinical effectiveness of hand-held continuous wave dopplers in the local setting especially in primary uncomplicated varicose articles veins. All electively referred patients with primary uncomplicated varicose veins who were referred to the Varicose Vein Clinic were evaluated with continuous-wave handheld Doppler (CWD) and duplex ultrasound (DUS) examination. The study duration was from the 1st of July to 31st of August 2013 (2 months). All patients in the study were independently evaluated with CWD and DUS in the clinic on the same day after adequate rest time. DUS was taken as the gold standard for evaluation of CWD specificity and sensitivity. The Chi-square and T-test was used to test for statistical significance. A total of 41 patients were evaluated in this study. The specificity of CWD when compared to DUS for diagnosing Sapheno-femoral junction (SFJ) was 100% and at the Sapheno-popliteal junction (SPJ) was 87%. Meanwhile sensitivity of CWD for SFJ was 75% and SPJ was 60%. The examination time with CWD was significantly faster than when compared with DUS examination with significant faster tracing times that can be achieved with CWD. CWD also significantly shorter reflux times when compared to DUS. Continuous-wave handheld doppler proves to be an indispensable clinical tool in the evaluation of SFJ and SPJ reflux in varicose veins. CWD assessment in this study was shown to be equal if not better for evaluating reflux when compared to DUS assessment for SFJ reflux. Main advantages for CWD also lie in its low running cost, rapidity in assessment and short learning curve when compared to duplex ultrasound examinations.

  8. Fulltext Acute Metabolic Changes with Thigh-Positioned Wearable Resistances during Submaximal Running in Endurance-Trained Runners
    Field AP, Gill N, Macadam P, Plews D
    Sports (Basel), 2019 Aug 01;7(8).
    PMID: 31375020 DOI: 10.3390/sports7080187
    The aim of this study was to determine the acute metabolic effects of different magnitudes of wearable resistance (WR) attached to the thigh during submaximal running. Twenty endurance-trained runners (40.8 ± 8.2 years, 1.77 ± 0.7 m, 75.4 ± 9.2 kg) completed six submaximal eight-minute running trials unloaded and with WRs of 1%, 2%, 3%, 4% and 5% body mass (BM), in a random order. The use of a WR resulted in a 1.6 ± 0.6% increase in oxygen consumption (VO2) for every 1% BM of additional load. Inferential based analysis found that the loading of ≥3% BM was needed to elicit any substantial responses in VO2, with an increase that was likely to be moderate in scale (effect size (ES) ± 90% confidential interval (CI): 0.24 ± 0.07). Using heart rate data, a training load score was extrapolated to quantify the amount of internal stress. For every 1% BM of WR, there is an extra 0.17 ± 0.06 estimated increase in training load. A WR ≥3% of BM was needed to elicit substantial responses in lactate production, with an increase which was very likely to be large in scale (ES ± 90% CI: 0.41 ± 0.18). A thigh-positioned WR provides a running-specific overload with loads ≥3% BM, resulting in substantial changes in metabolic responses.

  9. Acute ingestion of hydrogen-rich water does not improve incremental treadmill running performance in endurance-trained athletes
    Ooi CH, Ng SK, Omar EA
    Appl Physiol Nutr Metab, 2020 May;45(5):513-519.
    PMID: 31675478 DOI: 10.1139/apnm-2019-0553
    There is emerging evidence that hydrogen-rich water (H2-water) has beneficial effects on the physiological responses to exercise. However, few studies investigate its ergogenic potential. This randomized controlled trial examined the effects of H2-water ingestion on physiological responses and exercise performance during incremental treadmill running. In a double-blind crossover design, 14 endurance-trained male runners (age, 34 ± 4 years; body mass, 63.1 ± 7.2 kg; height, 1.72 ± 0.05 m) were randomly assigned to ingest 2 doses of 290-mL H2-water or placebo on each occasion. The first bolus was given before six 4-min submaximal running bouts, and the second bolus was consumed before the maximal incremental running test. Expired gas, heart rate (HR), and ratings of perceived exertion (RPE) were recorded; blood samples were collected at the end of each submaximal stage and post maximal running test. Cardiorespiratory responses, RPE, and blood gas indices were not significantly different at each submaximal running intensity (range: 34%-91% maximal oxygen uptake) between H2-water and placebo trials. No statistical difference was observed in running time to exhaustion (618 ± 126 vs. 619 ± 113 s), maximal oxygen uptake (56.9 ± 4.4 vs. 57.1 ± 4.7 mL·kg-1·min-1), maximal HR (184 ± 7 vs. 184 ± 7 beat·min-1), and RPE (19 ± 1 vs. 19 ± 1) in the runners between the trials. The results suggest that the ingestion of 290 mL of H2-water before submaximal treadmill running and an additional dose before the subsequent incremental running to exhaustion were not sufficiently ergogenic in endurance-trained athletes. Novelty Acute ingestion of H2-water does not seem to be ergogenic for endurance performance. A small dose of H2-water does not modulate buffering capacity during intense endurance exercise in athletes.

    A qualitative research was carried out in Besut and Kuala Terengganu to identyy adolescents’ health problems and needs jiom adolescent perspective, and to establish a priority area in the development of Adolescent Health Clinic in the district. A total of 61 adolescents were selected and divided into four groups and stratified according to age, 13-15 years old and 16 - 17 years old. Generally all participants wished to live in an environment free hom negative health risk factors. The obstacles they perceived were mainly related to lack of care or too much control by their parents. Some of them perceived that their parents in general had inadequate knowledge and skills on parenting. Among local behavioural problems mentioned were loafing, running away from home, vandalism, school absenteeism, aggressive behaviour, substance abuse, pre-marital sexual activities, "bohsia", “bohjan" and even involvement in crimes. More than hah' agreed that counselling service is important for adolescents, and it should be made available in the community preferably outside the schools. They perceived an adolescent friendly health clinic concept as an important concept that should be introduced. To them adolescent friendly health clinic is a clinic run by professionals who are knowledgeable, caring, good listeners, non—judgemental, and who exercise confidentiality. The clinic preferably should be situated in a location which is away from the present health facilities to avoid the image of a place for sick people. Clinic hours preferably during weekends, should provide appropriate technologies and situated in a comfortable ambience. Adolescent participation in the clinic was also mentioned as an important entity for adolescent friendly health services.

  11. Aerial and Terrestrial Patterns: A Novel Approach to Analyzing Human Running
    Gindre C, Lussiana T, Hebert-Losier K, Mourot L
    Int J Sports Med, 2016 Jan;37(1):25-9.
    PMID: 26509380 DOI: 10.1055/s-0035-1555931
    Biomechanical parameters are often analyzed independently, although running gait is a dynamic system wherein changes in one parameter are likely to affect another. Accordingly, the Volodalen® method provides a model for classifying running patterns into 2 categories, aerial and terrestrial, using a global subjective rating scoring system. We aimed to validate the Volodalen® method by verifying whether the aerial and terrestrial patterns, defined subjectively by a running coach, were associated with distinct objectively-measured biomechanical parameters. The running patterns of 91 individuals were assessed subjectively using the Volodalen® method by an expert running coach during a 10-min running warm-up. Biomechanical parameters were measured objectively using the OptojumpNext® during a 50-m run performed at 3.3, 4.2, and 5 m·s(-1) and were compared between aerial- and terrestrial-classified subjects. Longer contact times and greater leg compression were observed in the terrestrial compared to the aerial runners. The aerial runners exhibited longer flight time, greater center of mass displacement, maximum vertical force and leg stiffness than the terrestrial ones. The subjective categorization of running patterns was associated with distinct objectively-quantified biomechanical parameters. Our results suggest that a subjective holistic assessment of running patterns provides insight into the biomechanics of running gaits of individuals.

  12. An integrated geophysical study of the quaternary basin at Olak Lempit – Banting Area, Selangor, Malaysia
    Abdul Rahim Samsudin, Umar Hamzah, Zuraidah Ramli
    Sains Malaysiana, 2007;36:159-163.
    An integrated geophysical study was conducted to investigate the subsurface regional structure and the presence of a Quaternary sedimentary basin in the Olak Lempit - Banting area of Selangor, Malaysia. A regional gravity survey and the high resolution reflection seismic were employed to determine the thickness and areal distribution of the alluvial sedimentary basin as well as to investigate the depth and topography of the bedrock in the study area. The sedimentary basin hosts one of the most important coastal alluvial aquifer which was used to cater the shortage of domestic water supply during the worst water crisis that hit the state of Selangor in 1998. The surface geological map shows that in general 70% of the study area is covered by Quaternary deposits of Beruas, Gula and Simpang Formations which overlie the sedimentary bedrock of Kenny Hill Formation. The Beruas Formation consists of mainly clay, sandy clay and peat of Holocene fluviatile-estuarine deposits, whereas the Gula Formation represents Holocene marine to estuarine sediments which mostly consists of clay and minor sand. The Simpang Formation (Pleistocene) is a continental deposit comprising of gravel, sand, clay and silt. The underlying Kenny Hill Formation consists of a monotonous sequence of interbedded shales, mudstones and sandstones. The rock is Carbonaceous in age and it forms an undulating surface topography in the eastern part of the study area. A total of 121 gravity stations were established using a La Coste & Romberg gravity meter and the elevations of most of the stations were determined barometrically using Tiernan-Wallace altimeters. The high resolution seismic reflection using the common mid point (CMP) or roll along technique was carried out using a 24 channel signal enhancement seismograph and high frequency geophones. A total length of about 1.7 km stacked seismic section has been acquired in this survey and a nearby borehole data was used for interpretation. A relative Bouguer anomaly map shows an elongated zone of low gravity anomaly trending approximately NW-SE which is interpreted to be the deposition center of the Quaternary basin. The interpreted gravity profiles running across the central area of the study area show that the basin has thickness varies from tenth to several hundred meters with maximum depth to bedrock of about 275m. A gravity profile which passes through the eastern edge of the basin was modeled with depth to bedrock of about 178m below ground which agrees very well with those obtained from the interpreted seicmic section and borehole data. The stacked seismic section shows several high amplitude parallel to sub-parallel reflection overlying discontinuos and low reflection pattern. Reflections on the eastern part of the section is much shallower than the one observed on the western part which clearly indicates the presence of basinal structure with a total interpreted depth to bedrock of about 200 meters.

    Link analysis algorithms for Web search engines determine the importance and relevance of Web pages. Among the link analysis algorithms, PageRank is the state of the art ranking mechanism that is used in Google search engine today. The PageRank algorithm is modeled as the behavior of a randomized Web surfer; this model can be seen as Markov chain to predict the behavior of a system that travels from one state to another state considering only the current condition. However, this model has the dangling node or hanging node problem because these nodes cannot be presented in a Markov chain model. This paper focuses on the application of Markov chain on PageRank algorithm and discussed a few methods to handle the dangling node problem. The Experiment is done running on WEBSPAM-UK2007 to show the rank results of the dangling nodes.

  14. Application of parallel ensemble Monte Carlo technique in charge dynamics simulation
    Othman A, Umar R, Gopir G
    Sains Malaysiana, 2008;37.
    In the past, simulating charge dynamics in solid state devices, such as current mobility, transient current drift velocities are done on mainframe systems or on high performance computing facilities. This is due to the fact that, such simulations are costly in terms of computational requirements when implemented on a single processor-based personal computers (PCs). When simulating charge dynamics, large ensembles of particles are usually preferred, such as exceeding 40000 particles, to ensure a numerically sound result. When implementing this type of simulation on a single processor PCs using the conventional ensemble or single particle Monte Carlo method, the computational time is very long even on the fast 2.0 MHz PCs. Lately, a more efficient, easily made available tools and cost effective solution to this problem is the application of an array of PCs employed in a parallel application. This is done using a computer cluster network in a master-slave model. In this paper we report the development of a LINUX cluster for the purpose of implementing parallel ensemble Monte Carlo modelling for solid states device. We have proposed the use of Parallel Virtual Machine (PVM) standards when running the parallel algorithm of the ensemble MC simulation. Some results of the development are also presented in this paper.

    PMID: 30984885 DOI: 10.1016/j.heliyon.2019.e01427
    In paddy cultivation, harvesting is the most important operation, which needs suitable machinery. Thus, this study was carried out to compare field performances and energy and environmental effect between the conventional 5 m cutting width NEW HOLLAND CLAYSON 8080, 82 kW@2500 rpm combine harvester running on a total net area of 42.78 ha of plots for two rice (Oryza sativa L.) cultivation seasons and the new mid-size 2.7 m cutting width WORLD STAR WS7.0, 76 kW@2600 rpm combine harvester running on a total net area of 16.95 ha of plots for two rice cultivation seasons. The conventional combine as compared to mid-size combine showed 14.4% greater mean fuel consumptions (21.13 versus 18.46 l/ha), 31.1% greater mean effective field capacity (0.69 versus 0.53 ha/h), 5.23% greater cornering time (turning time) percentage of total time (8.28% versus 3.05%) and 1.41% greater reversing time percentage of total time (7.2% versus 5.79%) but 20.90% lesser mean operational speed (3.24 versus 4.10 km/h), 11.69% lesser effective time percentage of total time (60.0%versus 71.69%h/ha), 10.8% lesser mean field efficiency (64.3% versus 72.1%). In terms of total energy use the conventional combine showed 24.64% greater mean total energy use in the harvesting operation (1445.81 versus 1160.00 MJ/ha), 14.46% greater mean fuel energy (1010.014 versus 882.39 MJ/ha), 56.47% greater mean machinery energy (431.32 versus 275.65 MJ/ha) and 59.25% greater mean human energy (3.48 and 2.18 MJ/ha), this cause 26.12% greater mean total Green House Gas emission (GHG) than the mid-size combine. The results revealed that the mid-size combine is more suitable in conducting the harvest operation in rice field in Malaysia than the conventional combine.

    Movement Health & Exercise, 2012;1(1):11-23.
    MyJurnal
    The combined metabolic and thermoregulatory demands experienced during exercise in the heat impose an exceptional stress on the circulatory system. To date, much of what is known about circulatory stress during exercise in the heat has focused on primarily dry environment (~ 40% rh)
    with limited studies carried in higher humidity (> 60% rh) conditions. This study was designed to investigate the influence of humid condition on circulatory responses during prolonged intense running exercise among elite runners. On separate days, 11 male elite runners ran for 60 minutes at
    an intensity of 70% max across three different humidity levels of HH (71% rh), NH (43% rh) and LH (26.2% rh) with the ambient temperature set at 300C. Thermal stress was found to increase during exercise in the HH condition as both Tre and Tsk steadily rise across time. Circulatory stress markedly increased during exercise in higher humidity levels. Heart rate was significantly higher in the HH condition with its level increasing to 92% of HRmax. The upwards drift in HR was significantly higher in HH within the last ten minutes of exercise. Contrary, stroke volume recorded a
    steady decline during exercise with a significantly lower SV in the HH as compared with the NH and LH. Results implicate rising humidity level will impose greater circulatory stress during prolonged intense exercise. The consequence from this circulatory stress will result in limited ability for an athlete to sustain his exercise capacity when HR reaches maximal level.

    MyJurnal
    A study was undertaken amongst private primary care providers in three urban centres of Malaysia to understand the organizational structure of the facilities and to assess the cost of running such services. A total of 150 clinics were involved in the study. Data was collected through interviews with owners of the clinics using semi-structured questionnaires. Solo-practitioners owned 64.7% of the clinics while 35.3% of them were owned by group practice. This study showed that the mean number of patients visited the clinics daily was 49.3 with the average operating hours of 79.4 hours/week (range 28.0 - 168.0 hours/week). Group practice clinics operates 23.9 hours longer than solo-practice clinics. Group practice clinics were more likely to offer 24 hours service than solo-practice clinics. Most of the clinics were manned by a single doctor (57.3%), 30.0 % had two doctors and only 12.7% were run by more than two doctors. On average, group practice employed greater number of supporting staff than solo-practice clinics (6.0 vs 4.3 people). The mean annual cost to run each facility was found to be RM 444,698. The mean cost per patient was found to be RM 32.09 for solo-practice clinics and RM 38.55 for group practice. Wages represented the highest proportion in the recurrent cost (61.1%) followed by drugs (29.2%) and consumables (2.7%). Building cost (67.9%) and equipment cost (25.9%) were the major capital costs for the clinics. This study could serve as a basis to reimburse private primary care providers in the future health financing scheme in Malaysia. To improve efficiency and contain cost in primary care settings, efforts should be targeted towards cost of wages and drugs utilised by the providers in their daily practice.

    In the mol-ecule of the title compound, C21H17N3O2, the 5,6-di-hydro-benzimidazo[1,2-c]quinazoline moiety is disordered over two orientations about a pseudo-mirror plane, with a refined occupancy ratio of 0.863 (2):0.137 (2). The dihedral angles formed by the benzimidazole ring system and the benzene ring of the quinazoline group are 14.28 (5) and 4.7 (3)° for the major and minor disorder components, respectively. An intra-molecular O-H⋯O hydrogen bond is present. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming chains running parallel to [10-1].

    This study aims to examine the decision making by rugby sevens referees, and its relationship with the referees' performance. The instruments used in this study are the Rugby Referee Decision Making Test (α=.74) and the Referee Sevens Field Performance Evaluation (α=.94). It was administered to 132 rugby sevens referees (mean age 33.4 + 1.5 years; 132 males) from the Malaysian Rugby Union (MRU), which have been refereeing in 10 rugby sevens tournaments in Malaysia. Descriptive and Inferential statistics (one way ANOVA and Pearson's Correlation) were employed to analyse the data. Decision Making ( ̅= 24.13, SD=5.24) and performance ( ̅= 136.45, SD = 4.47) were identified at a moderate level. The findings indicated no significant differences [F= (3, 128) =.246, p>0.05] in the decision making across age level, but there were significant differences [F= (3, 128) =63.159, p
