Playful Practices With Children With Intellectual Disabilities
Authors: Mero Piedra Angélica Liseth
Published: August 2020

This article aims to promote and support the physical education teacher's community in the use of playful practices with pupils with mild intellectual disabilities (MID), as a didactic medium, and a substantial educational resource of quality physical education.  Firstly, it will be reviewed definitions and emergent themes on the subject shaping the theoretical framework on which this study has been built. Later, it will be presented didactic advice and guidelines for the application of playful practices, extracted from the most effective observable practices in the author's teaching experiences in specialized education institutions with pupils with MID and supported by the scientific literature. This article reinforces the notion that playful practices provide variety to meaningful learning, have great potential as a facilitator in pedagogical processes, and provide an appropriate educational response to pupils with intellectual disabilities. It also shows that teachers should reflect positive and reflective disposition to modifications and adaptations of the different elements involved in the playful practices according to educational objectives and the personal needs and interests of the children with MID. Considerations such as the instructions have to be modified to meet students’ needs, play according to children's biological age and systematic registration and monitoring in the teaching-learning process are essential. It is recommended that teachers share their experiences in pedagogical practice to learn from our differences and strengthen our coincidences, to contribute to the still insufficient bibliography in the pedagogical practices in special education.

Published: August 2020

Purpose: The paper aimed to assess the gait pattern in children and adolescents with juvenile idiopathic arthritis (JIA) treated at the rehabilitation center and to assess changes in this pattern after the end of treatment and 9 months later. Methods: 50 children with JIA were enrolled into the study. 35 healthy volunteers were enrolled into the study for a comparison. Spatiotemporal and kinematic gait parameters were obtained using a movement analysis system. The Gait Deviation Index (GDI) was calculated. The assessment was performed three times: on the day of admission to the rehabilitation center, after the end of a 4-week treatment period and 9 months later. Results: With regard to the majority of spatiotemporal and kinematic parameters, differences in their distribution were highly statistically significant between the study group and the control group (p < 0.001). In two subsequent tests, differences were less significant when compared to the control group (p < 0.01). In the study group, ranges of motion in the sagittal plane in the hip (p < 0.01), knee (p < 0.001) and ankle joints (p < 0.01) increased significantly between tests 1 and 2, and 1 and 3. A significantly lower value of GDI was observed in the study group (right limb; p = 0.036). Conclusions: The gait pattern of children with JIA is significantly different from the one observed in healthy children. A rehabilitation program significantly improved gait in children with JIA, but differences compared to healthy children were still observed, and it indicates that the abnormal gait pattern became permanent in this group of subjects.

Authors: Prochor Piotr , Frossard Laurent , Sajewicz Eugeniusz
Published: August 2020

Purpose: This study attempted to establish the link between design of implants for bone-anchored prostheses and stress-shielding, affecting the stability of the bone-implant coupling using numerical approach. The objectives were to share a numerical model capable to evaluate the long-term stability of implants and to use this model to extract data sets showing how shape and material stiffness of threaded, press-fit and modular press-fit implants affect stress-shielding intensity. Methods: Three designs were considered: threaded, press-fit and modular press-fit. The effect of shape and material stiffness of each design on stress-shielding intensity was assessed using Young’s modulus (10 to 210 GPa). Furthermore, the impact of the diameter of percutaneous part (10 to 18 mm) and thickness of medullar part (5 to 1 mm) was investigated for the modular press-fit implant. Results: The threaded design generated 4% more bone mass loss at the distal femur but an overall loss of bone mass was by 5% lower to press-fit design. The influence of Young’s modulus on bone mass changes was noticeable for modular press-fit implant, depending on diameter of percutaneous or medullary part. A 20 GPa change of stiffness caused a bone mass change from 0.65% up to 2.45% and from 0.07% up to 0.32% for percutaneous parts with 18 mm and 10 mm diameter, respectively. Conclusions: Results suggested that threaded implant provides greater stability despite an increased bone loss at the distal femur. Altogether, this work provided an initial model that could be applied in subsequent studies on the long-term stability of current and upcoming implants.

Published: August 2020

Purpose: The aim of this work was to assess the impact of Nordic walking on sagittal spinal curvatures and isokinetic trunk muscle endurance in women after breast cancer treatment. Methods: Thirty-nine breast cancer survivors were divided into two groups: a study group (n = 19) that performed Nordic walking, and a control group (n = 20) that performed a standard general exercise programme. Body posture was assessed using Moiré photogrammetry and trunk muscle (flexors and extensors) endurance at 120°/s was measured isokinetically. Statistical analyses were based on two-way ANOVA with Scheffe post hoc tests and Pearson’s r correlation tests. Results: Women who completed the 8-week Nordic walking intervention showed significant improvements in average power and total work, irrespective of the muscle group investigated. Following training intervention, greater strength-velocity values of the trunk muscles were observed in the study group, compared to the control group. There were no significant changes in postural parameters or correlations for trunk muscle function within spinal curvatures before and after the training interventions. When both groups were combined (Nordic walking + general exercises), functional-postural correlations following the intervention showed a statistically significant tendency toward a reduced inclination of the upper thoracic section, together with increases in all tested functional parameters of the trunk flexor and extensor muscles (r = –0.33 to r = –0.37). Conclusions: Compared to a standard general exercise programme, Nordic walking is more effective for improving isokinetic trunk muscle endurance in women after breast cancer. However, no changes in sagittal spinal curvatures were observed after the 8-week Nordic walking and general exercise interventions.

Published: August 2020

Purpose: The polymeric porous surface of fibres (PLA) may influence the kinetics of release of biologically active compounds (gentamicin, G and ethacridine lactate, R) affecting development of a bacterial biofilm. Methods: The porous fibres with different morphology were manufactured by the electrospinning method from ternary systems composed of PLA and selected solvents. Fibres morphology was examined using a scanning electron microscopy (SEM), their structure was analyzed by FT-IR ATR spectroscopy and differential scanning calorimetry (DSC). Changes in the drug release profile were measured using ICP/UV-Vis methods and the resulting bactericidal or bacteriostatic properties were tested by two-layer disk diffusion test in relation to various drug incorporation methods. Results: The porous fibres can be applied to produce drug-bearing membranes. The spectroscopic studies confirmed incorporation of gentamicin into the fibres and the presence of ethacridine lactate on their surface. Bimodal fibres distribution (P3) promoted faster release of gentamicin and ethacridine lactate from P3G and P3R materials. The electrospinning process coupled with the vapor induced phase separation influenced the glass transition temperature of the porous polymer fibres. The pre/post-electrospinning modification influenced the glass transition, maximum temperature of cold crystallization and melting point of the porous membrane, compared to the neat polymer. The polylactide fibres with gentamicin showed strong bactericidal effect on Gram-positive bacteria, while fibres with ethacridine lactate were bacteriostatic. Conclusions: The obtained fibres with complex surface morphology can be used as a membrane in active dressings as they make it possible to control the release profile of the active compounds.

Published: August 2020

Purpose: This study aimed to analyze the changes of the stress distributions in TMJs for the pre- and postoperative patients with mandibular prognathism under unilateral occlusions, a frequent occlusion in mastication. Methods: Pre- and six-mouth postoperative cone-beam computed tomography images of thirteen patients diagnosed with mandibular prognathism were scanned and used to construct complete maxillofacial models, assigned as the Pre and Post group, respectively. Another ten asymptomatic individuals were defined as the Control group. The inhomogeneous properties were assigned to the models. The muscle forces and boundary conditions corresponding to left and right unilateral occlusions were applied on the models. The analysis of variation (ANOVA) was chosen for the comparison among the groups. Results: The results showed that the Pre group had abnormal stress distributions ang higher stress level in TMJs, compared with those of the Post and Control groups. Moreover, from clinical cases, symptoms of temporomandibular disorders (TMDs) always followed with increased stresses. Conclusion: Generally, orthognathic surgeries could improve the stress distribution in TMJs of the patients with mandibular prognathism under the unilateral occlusions. However, the postoperative complications, especially symptoms of TMD, were closely related to changes of stress for patients with mandibular prognathism after orthognathic surgeries. Individual virtual surgery and finite element analysis should be conducted to prevent complications in TMJ.

Authors: Yogi Tri Prasetyo
Published: August 2020

Military camouflage plays a critical survivability component of the front-line soldiers. The purpose of this study was to evaluate the existing military camouflage effectiveness across Southeast Asian countries using Camouflage Similarity Index (CSI). CSI is a color-based image algorithm based on CIELAB color space. The value ranges from 0 to 1 and the best value 0 is achieved if the selected camouflage perfectly blends with the selected background. 10 existing military camouflage designs across Southeast Asian countries were evaluated under 7 different locations (20x50 pixels) from 1 selected woodland background. Each location had different L*, a*, and b* values. Post-hoc Tukey test showed that there was no significant difference between camouflage, indicating that the existing Southeast Asian Military camouflage had equal effectiveness of concealment on the selected woodland background. This study represents the first attempt to investigate the effectiveness of Southeast Asian military camouflages. The results of this study could be very beneficial for Southeast Asian military organizations, academicians, and camouflage manufacturer in terms of finding the enhanced direction from the current design which subsequently enhances the survivability of the front-line soldiers.

Discomfort due to riding a motorcycle is an issue that need to be addressed as it has long-term effects of musculoskeletal disorders on motorcyclists especially among occupational motorcyclist. Thus, this study was conducted to analyse the rating of muscle discomfort and correlation with the risk factors among traffic police riders. A cross-sectional study was carried out among 137 male traffic police riders (high-powered motorcycle) with the age between 20 to 39 years old. The 100-mm visual analogue scale questionnaire included ratings of perceived discomfort scales for 20 specific body regions was used in the study. The results indicate that the lower back (left and right) were the highest mean of discomfort which were 56.6 mm and 55.9 mm respectively. This followed with right (48.5±36.2 mm) and left (48.4±30.3 mm) upper back, and right hand (47.0±33.0 mm). The mean of overall discomfort ratings for all regions were more than 20 mm.  Besides, there is a strong positive significant correlation between duration of ridings (hours) and overall discomfort ratings (p<0.01, r=0.785) and moderate positive correlation between year of traffic police motorcycle riding experience and overall discomfort ratings (p<0.01, r=0.410). As a conclusion, cumulative riding hours, riding experience and no support of the back area of the body in motorcycle seat, are the most concern in this study as this are the contributing factors to the muscle discomfort among traffic police riders while riding high-powered motorcycle. Thus, this study suggested an additional feature is needed in current motorcycle design in order to enhance comforts of traffic police riders. Also, it will improve the condition of traffic police riders’ discomfort and indirectly also improve their work and health performance as well as productivity.

Published: August 2020

Nurse is a profession that has a quite high workload. It can be seen from how often they should encounter situations which compel them to undergo precisely right decision in saving patients’ lives. Various environmental conditions increase the frustration rate of the nurses, such as noise of the crowds and medical equipment, as well as smell of medicines and wounds at once. Moreover, demands from the patients’ family make it even tougher for them. Therefore, this study aims to measure the mental workload of the nurses at Intensive Care Unit (ICU) and emergency unit (IGD) in the Hospital ZA based on their years of service. The study was conducted using the method of NASA-TLX (National Aeronautics and Space Administration – Task Load Index). It measured the workload in six dimensions: Mental Demand (MD), Physical Demand (PD), Temporal Demand (TD), Own Performance (P), Effort (EF), and Frustration Rate (FR). The results of the study show that the average value of the nurses’ workload at ICU and IGD is in the category very high (respectively 80 and 83) for the nurses with 0-3 years of service, and the most contributing factor for both the primary groups is the effort (EF).

Published: August 2020

Women are likely to leave the job sector as a result of the crisis between their commitments to the career with the household interest. In response to this issue, this study aims to build a career challenge model that caters to the demand among women in this century. Hence, this study has identified the key factors to the challenges faced by female engineers in pursuing their career as an engineer through the Delphi Modified Technique. The result shows this study looking into the relationship between four independent constructs namely, life balance, childcare, leaves and gender discrimination. Meanwhile, the dependent construct of this study is career challenges faced by women. The scope of the study comprises female engineers with families and 211 respondents were selected to answer the questionnaire. The data obtained were analysed using the PLS-SEM 2.0 software via the algorithm, bootstrapping and blindfolding method. The construction process of this model involves two tests including the construction of the measurement model and the structure model. Testing the measurement model involves internal consistency namely (a) convergent validity and (b) discriminant validity in which these two validities have six analyses; (i) external loading, (ii) composite reliability, (iii) average variance extracted (AVE), (iv) Fornell-Larcker, (v) cross loading, and (vi) Heterotrait-Monotrait Ratio (HTMT). Meanwhile, the structural model testing involves the analysis of (i) Multicollinearity (Inner VIF), (ii) Path Coefficient, (iii) R square (R2), (iv) size effect (f2), and (v) Predictive Relevance (Q2). The findings indicate that gender discrimination and life balance have significant relationships in influencing career challenges. Hence, this model is expected to contribute to the literature of Human Resource Management.

Most available data on the prevalence and characteristics of low back pain (LBP) are reported in developed countries. The aim of this study was to investigate the prevalence of LBP and potential risk factors among a group of workers in Malaysia. A cross-sectional study was conducted among 170 workers in a fertilizer company in Malaysia. The sample comprised both blue- and white-collar workers. A set of questionnaires consisting of sociodemographic items, the NORDIC musculoskeletal questionnaire and the Dutch Musculoskeletal Questionnaire was used for this study. The main analysis conducted was a multivariate logistic regression. Results showed that a total of 40% of workers experienced LBP. Compared to workers younger than 30 years of age, the risk of LBP was 8 times higher among those over 50 years of age. In addition, workers who were moderately stressed at work had a risk of LBP that was almost five times higher, and workers who did not have awkward posture for a long period of time had an 80% lower risk of LBP. In a multivariate logistic regression, after adjusting for sociodemographic variables, it was found that less repetitive work, shorter sustained positions and less frequent lifting of heavy objects prevented LBP. After the final adjustment including all other variables, only engaging in repetitive work was associated with LBP. In conclusion, each workplace should ensure that older workers, especially those who are working in stressful environments, are prevented from engaging in repetitive work, sustaining prolonged awkward postures and lifting heavy objects.

Using physicochemical methods of analysis (XRF and AAS), the elemental composition of urban soils of large urban ecosystems of one of the industrially developed regions of Russia was studied. It was revealed that most of the soils of urban ecosystems have technogenic anomalies in a number of heavy metals and metalloids: As, Co, Ni, Pb, Zn, Cr. An abnormally high iron content in the soils of the region was established compared with the world level and clarke of element in the soils. Without exception, all studied urbanozems are characterized by a high S content. Territories with a moderately hazardous and dangerous pollution level, which amounted to 20% of the studied urban ecosystems, respectively, were identified by the total pollution index. Sources of toxic elements in urban soils are metallurgical, defense, metalworking and chemical industries. The industrial production and toxicant-polluted urban soils considered in the article are a potential source of pollution of natural waters and surface layers of the atmosphere. The soils of cities and sanitary protection zones of industrial enterprises with geochemical anomalies require bioremediation

The effect of shared distinctiveness on source memory: An event-related potential study
Authors: Weigl Michael , Pham Hong Hanh , Mecklinger Axel , Rosburg Timm
Published: August 2020

An illusory correlation (IC) is the erroneous perception that two actually uncorrelated categories are correlated. The Shared Distinctiveness Approach (SDA) explains ICs with heightened accessibility of distinctive category combinations in episodic memory. However, empirical evidence for this approach is heterogeneous. In the present event-related potential (ERP) study, we exploited the fact that more distinctive items elicit larger P300 responses than less distinctive items, which potentially predict subsequent memory performance differences for such items. Distinctiveness at encoding was created by presenting words that differed from frequently presented, positive words in valence, font color, or both. We hypothesized that shared distinctiveness (deviation in both color and valence) would lead to an enhanced P300 subsequent memory effect (SME), better source memory performance, and an overestimation of the frequency of shared distinctive items. Behavioral results indicated the presence of shared distinctiveness effects on source memory and frequency estimation. Unexpectedly, memory also was enhanced for positive items in the frequent color. This pattern also was reflected in the P300 for highly positive and negative items. However, shared distinctiveness did not modulate the P300 SME, indicating that the processing of distinctive features might only indirectly contribute to better encoding. This study shows that shared distinctiveness indeed is associated with better source memory and ICs. Because effects were observed for the most frequent and the least frequent category combination, our results imply that the processing of distinctiveness might involve attention allocation to diametrical category combinations, thereby accentuating the differences between the categories.

Background: The current COVID-19 pandemic has affected almost 17.3 million victims worldwide with mortality of almost 674K. Pregnancy is one of the most susceptible conditions for COVID-19 infection, but limited data is currently available about the clinical characteristics of pregnant women with the disease. Objective; to describe the clinical characteristics, co-morbidities, management, feto-maternal, and neonatal outcome in COVID-19 positive pregnant women.

Methodology: A descriptive case series study was conducted in Obs/Gynae dept of Benazir Bhutto Tertiary Care Hospital, Rawalpindi, including all asymptomatic/symptomatic COVID-19 positive pregnant women and clinical suspects (COVID-19 PCR negative women) delivered in our hospital from 01st April 2020 to 31st July 2020. Their medical records were reviewed for clinical characteristics, management, feto-maternal and neonatal outcomes. Continuous variables were expressed in Mean & Range and Categorical variables as number & Percentage. Results: During the study period a total of 17 cases were reviewed. The mean maternal age was 28.94 yrs. Primigravida (07), Multipara (10). Mean gestational age was 37 wks (range; 30-41wks). Presenting symptomatology was varied. Asymptomatic; (29%), COVID-19 specific symptoms; fever & flu (12%), fever&cough (6%), shortness of breath(SOB) alone (6%), fever & SOB(6%) and pregnancy-related manifestations were labour pains (17%), eclampsia(6%), hydrocephalous fetus (6%) and hepatic encephalopathy(6%). The commonest co-morbidity was Hypertensive disorders of pregnancy (24%). Five women (29%) required ICU care. Lower segment caesarean sections(LSCS) (59%), vaginal delivery (41%). Eleven babies delivered with good Apgar score and birth weight. Two were early neonatal deaths (ENND) and 04 were received intra-uterine fetal deaths (IUDs). Fetal demise was associated with strong obstetric risk factors. Out of 13 live-born babies, RT-PCR Covid-19 testing was done in 10 (77%) cases and was negative. One mother was expired due to complications of hepatic encephalopathy, sepsis, and burst abdomen.

Conclusion; The clinical course of COVID-19 disease in pregnancy seems to be no different from non-pregnant women. Clinical manifestations are diverse and infection contracted in the third trimester of pregnancy is associated with good feto-maternal and neonatal outcomes.
Analogical Methods in Legal Informatics
Authors: Čyras Vytautas , Lachmayer Friedrich
Published: August 2020

The law occurs in a dual mode: a basic mode and an expert mode. In the basic mode, people predominantly experience the law in a situational and not a textual way. The people on the street move according to the consuetudinary law. In the expert mode, the law goes up textually to the professional lawyer. It becomes mostly about argumentation in professional language rather than natural language. Digitalisation encompasses both these modes. The extent to which digitalisation is visible is another issue. We argue that analogical thinking continues to be important in law and that this must be considered in legal informatics.
