Published: February 2018

Introduction:According to the latest UNICEF report, Polish children put on weight at the highest pacein Europe. The number of overweight children has doubled in the last decade. The aim of the work was to assess the effects of kinesiotherapy implemented during a 3-week rehabilitationcamp on changes in motor skills parameters measured on the Leonardo dynamometric platform (Novotec Medical) and on body mass in patients with simple obesity. Materialand methods:The study group included 32 children and youth aged 7-16 with simple obesity who underwent an exercise programme during a 3-week rehabilitation camp. The subjects were examined twice, i.e. at the beginning and at the end of the camp. The control group consisted of 70 healthy children within the same age range who were examined once. Body mass and body height were measured and the BMI was calculated (taking into account centile charts) for all the study participants. Motor skills were assessed on the basis of avertical jump performed on the Leonardo GRFP (GroundReaction Force Platform). The following data were registered: jump velocity, maximum jump height, strength, power, power with reference to body mass and the Esslinger Fitness Index (EFI). Daily kinesiotherapy included exercises in the form of circuit training and water exercises. All the patients participated in meetings with a dietician and a clinical psychologist. Results:Statistically significant reduction in body mass after a 3-week rehabilitation camp was noted in 27 patients with simple obesity (84.1%) (p<0.05). Motor parameters did not improve significantly. Conclusions:Regular physical activity resulted in weight loss only. However, physical activity did not bring about positive changes in motor parameters.

Published: February 2018

Introduction: In order to assess hand spasticity in post-stroke patients, it is necessary to apply an objective and sensitive method which allows for characterising motor control. It is significant due to the necessity to monitor the effects of the therapeutic process according to the requirements of Evidence-Based Medicine (EBM). The aim of the study was to assess the usefulness of the measurement of pressure generated during a maximal palmar grasp and after its release for evaluating the level of hand motor control in poststroke patients compared to subjective scales. Material and methods: In order to characterise motor control, a numerical indicator calculated on the basis of the measurements of pressure generated during a maximal palmar grasp and after its release was suggested. To perform the measurements, 12 poststroke patients with hemiparesis were included in the study. In the research, the level of hand paresis was assessed with Brunnström Approach, the intensity of spasticity was graded with Modified Ashworth Scale, while hand motor function was classified with Fugl-Meyer Assessment (FMA). Pressure generated during a palmar grasp and after its release as well as palm area were measured with the use of a photometric method. The assessment was made twice, i.e. on the day of admission to the in-patient rehabilitation ward and after a three-week hospital treatment. Results: In the second measurement, a slight decrease in paresis intensity according to Brunnström Approach and lower intensity of spasticity according to Ashworth Scale were noted. A higher number of points in the FMA scale was observed. The values of the suggested indicator changed; however, in no case were these changes statistically significant. Conclusions: 1. Compared to other subjective scales, the usefulness of the measurement of pressure generated during a maximal palmar grasp and after its release for assessing the level of hand motor control in post-stroke patients was not confirmed. 2. The usefulness of the recommended method of spastic hand motor control assessment needs to be verified in further research carried out according to EBM requirements.

Implementation Process of 5S for a Company in Real Life - Problems, Solutions, Successes
Authors: Czifra György
Published: February 2018

Developed in Japan, 5S is a system of organizing workplace for efficiency, effectiveness and safety. Is 5s important? The answer is: “YES”, because the implementation is about empowering employees to control their work area and create an environment where they want to work every day. It is a program that only works with grass roots level engagement. With commitment to safety, we are equally committed to 5S to ensure a safe place to work. It enabled us to indicate where waste was occurring and thus improve the work area sustainably. We recognized real problems, found solutions and ultimately we were successful in our endeavors. Throughout different companies, various words of similar meaning are used. No matter what specific words are used to identify the steps in 5S, the purpose remains the same: create a clean, organized and efficient work environment.
Myelodysplastic syndrome with myelofibrosis in a 12-year-old patient – A case report
Authors: Oltean Andreea , Chincesan Mihaela Ioana , Marginean Oana , Horvath Emoke
Published: February 2018

Myelodysplastic syndromes are a heterogeneous group of clonal disorders characterized by peripheral blood cytopenia and normal or hypercellular bone marrow with dysplasia in more than one blood cell lineage, unfavorable prognosis, and lack of response to treatment. We present the case of a 12-year-old male patient who was referred to the Hematology and Oncology Department of Pediatric Clinic I Târgu- Mures in May 2016, with splenomegaly and pancytopenia. The osteomedullary biopsy revealed myelofibrosis, discrete dysplasia of the myeloid series and megakaryocytes, blasts CD34+ approximately 10%, which led to the diagnosis of myelodysplastic syndrome with myelofibrosis. The myeloid precursors indicated a high risk of transformation into acute myeloid leukemia, so chemotherapy associated with corticosteroids was started, leading to slight improvements. Although myelodysplastic syndrome associated with myelofibrosis is rare at this age, despite the treatment and favorable progression in the case presented, in the absence of hematopoietic stem cell transplantation the prognosis remains unfavorable.

Published: February 2018

Background and aims:

Knowledge of pain characteristics among the healthy population or among people with minimal pain-related disability could hold important insights to inform clinical practice and research. This study investigated pain prevalence among healthy individuals and compared psychosocial and physical characteristics between adults with and without pain.

Methods:

Data were from 1,000 self-reported healthy participants aged 3–101 years (1,000 Norms Project). Single-item questions assessed recent bodily pain (“none” to “very severe”) and chronic pain (pain every day for 3 months in the previous 6 months). Assessment of Quality of Life (AQoL) instrument, New Generalised Self-Efficacy Scale, International Physical Activity Questionnaire, 6-min walk test, 30-s chair stand and timed up-and-down stairs tests were compared between adults with and without pain.

Results:

Seventy-two percent of adults and 49% of children had experienced recent pain, although most rated their pain as mild (80% and 87%, respectively). Adults with recent pain were more likely to be overweight/obese and report sleep difficulties, and had lower self-efficacy, AQoL mental super dimension scores and sit-to-stand performance, compared to adults with no pain (p<0.05). Effect sizes were modest (Cohen’s d=0.16–0.39), therefore unlikely clinically significant. Chronic pain was reported by 15% of adults and 3% of children. Adults with chronic pain were older, more likely to be overweight/obese, and had lower AQoL mental super dimension scores, 6-min walk, sit-to-stand and stair-climbing performance (p<0.05). Again, effect sizes were modest (Cohen’s d=0.25–0.40).

Conclusions:

Mild pain is common among healthy individuals. Adults who consider themselves healthy but experience pain (recent/chronic) display slightly lower mental health and physical performance, although these differences are unlikely clinically significant.

Implications:

These findings emphasise the importance of assessing pain-related disability in addition to prevalence when considering the disease burden of pain. Early assessment of broader health and lifestyle risk factors in clinical practice is emphasised. Avenues for future research include examination of whether lower mental health and physical performance represent risk factors for future pain and whether physical activity levels, sleep and self-efficacy are protective against chronic pain-related disability.
A prolegomenon to the researchers of the history of physical culture
Authors: Ilić Stefan
Published: February 2018

Truth, problems, research In his search for the truth, every history researcher often encounters the difficulties of methodological nature. A very complex path, which is, in case of history researchers, more difficult and complicated, due to a number of obstacles, leads to a discovery of truth. However, what exactly is the truth and how much do we need it nowadays, who wants it and is there a desire to discover the truth? These questions are not easy to answer. What are we faced with and what are the most common problems in the research of the history of physical culture? What makes us make omissions, errors and mistakes? 1. Hasting and hurrying to complete the papers, when we, often faced with short deadlines, fail to meet all methodological requirements. 2. Using the information from the papers by other authors is taken for granted, without adequate verification, assuming their reliability, and if the information is inaccurate, it results in multiplying inaccurate information which thus becomes an inaccurate secondary source to the next researcher. 3. In our research we are sometimes unable to distance ourselves from our nation, religion and politics and we therefore tend to overestimate the achievements by our own people. 4. We do not always pay enough attention to or we neglect or do not consider the economic, political, historical, cultural and other conditions under which an event occurred as well as their interrelations and their impact on the studied issue. 5. In research we often exclude comparative studies on the development and achievements of European countries and Serbia in all aspects of political, economic and cultural life. 6. Professional and scientific papers' review is easily accepted and taken for granted since, due to the authors' deadlines, we are often under pressure and forced to assess the suggested work without thorough and adequate consideration. For the aforesaid reasons, we therefore advocate a more cautious and more serious approach to the research of the past in order to avoid mistakes and inaccuracies.

Published: February 2018

Sokol movement originated in Czech lands in second part of 19th century, and soon after it spread to all Slavic countries, as also to the ones were Slavic people lived. Beginnings of Sokolism in Bosnia and Herzegovina relate to Herzegovina, specifically to Foča and Risto Jeremić, when in 1893 the first initiatives for the establishment of a Serbian soko society in this city were created. It has been more than five years before the establishment of the first "Pobratimstvo" ("Brotherhood", "Fraternity"), primarily anti-alcoholic, but also a society that had the characteristics of future Serbian soko societies. In 1910 this society was officially re-registered in the "Serbian Soko" in Foča. In the following years started a little more favorable period and other societies in the cities and other places of Herzegovina started to appear, which after a certain time entered also in Herzegovina village, which contributed to the development of the village, literacy of the people, but also many other useful things. These beginnings and the development of Sokolism on the territory of Herzegovina represent the main subject of this paper, with the aim to research and present when and how the first initiatives came to light, when the first societies were founded and who were the most important personalities. In addition, the authors want to show the significance of the Sokolism for the whole of Herzegovina and its population. During writing authors used historical method.

Published: February 2018

The Sokol movement, as an expressly Slavic cultural, national-liberational liberal movement originated in Czechoslovakia in 1862 under the patronage of Miroslav Tyrš. The aim of the Sokol organization was to unite all the Slavic peoples through physical exercise, under the slogan "Freedom, brotherhood, equality." The Sokol idea was made up of a synthesis of exercise and national culture. The Sokol movement in Serbia represented a part of a wealthy cultural and sports tradition. The Sokol rallies, competitions and public performances represented the manifestation of the Sokol physical exercise work and the display of Sokol might. Through all these manifestations one could over a shorter or longer period of time track the development of the Sokol exercise program. In addition, these manifestations represented the possibility of noting any drawbacks in the work of certain associations, parishes or societies. At the same time, these manifestations were also of a propaganda-mobilization character in the sense of promoting interest in the Sokol movement and the spreading of the Sokol idea. TheMoravskaSokol parish Niš organized eleven rallies from the time it was founded in 1920 to 1939.

For an integer b > 1 let (φb(n))n≥0 denote the van der Corput sequence base in b in [0, 1). Answering a question of O. Strauch, C. Aistleitner and M. Hofer showed that the distribution function of (φb(n), φb(n + 1), . . . , φb(n + s − 1))n≥0 on [0, 1)s exists and is a copula. The first and third authors of the present paper showed that this phenomenon extends to a broad class of subsequences of the van der Corput sequence. In this result we extend this paper still further and show that this phenomenon is also true for more general numeration systems based on the beta expansion of W. Parry and A. Rényi.

We formulate it as a conjectural uniform distribution in some sense, which elucidates data in previous papers.
Diagnostic Criteria for Identification of Microtus s. l. Species (Rodentia, Arvicolidae) of the Ukrainian Carpathians
Authors: Barkaszi Zoltán
Published: February 2018

The present paper deals with the issues of diagnostics of morphologically similar vole species (Microtus s. l.) common in the fauna of the Ukrainian Carpathians. Three groups of characters have been analysed: external traits (linear body dimensions, coloration features, etc.), morphological and anatomical features of the skull (size of its structures, form of certain bones and sutures, etc.), and morphology of molar teeth (number and form of enamel lobes and triangles). The analysis of museum specimens of voles collected in the region of the Ukrainian Carpathians has shown that external and cranial non-metric characters allow reliable identification to genus level, while for species diagnostics it is necessary to use a complex of characters including structural features of molars and dimensions of skull structures. The height and width of the braincase have the largest diagnostic value among cranial characters for the sibling species complex Terricola subterraneus–Terricola tatricus, while for the pair of morphologically similar species Microtus agrestis–Microtus arvalis such value have the upper molars length, condylobasal length, and braincase height. The most significant, revised and newly described, diagnostic characters have been generalized into an identification key, especially convenient for use during work with collection materials.

Madoni, SN, Costa, PB, Coburn, JW, and Galpin, AJ. Effects of foam rolling on range of motion, peak torque, muscle activation, and the hamstrings-to-quadriceps strength ratios. J Strength Cond Res 32(7): 1821–1830, 2018—To examine the effects of foam rolling (FR) on range of motion (ROM), peak torque (PT), hamstrings-to-quadriceps (H:Q) ratios, and muscle activation. Twenty-two recreationally active women (mean age ± SD = 21.55 ± 1.82 years, 161.91 ± 6.58 cm, 61.47 ± 10.54 kg) volunteered for this study. Participants performed pre- and posttests analyzing PT and surface electromyography (EMG) of their dominant limb, completing maximal knee extension and flexion at 3 different velocities. Participants foam rolled the hamstrings muscles or sat for the control condition between the pre- and posttests. Hamstrings ROM increased in the FR condition from (mean ± SE) 123.23 ± 3.49 to 126.41 ± 3.62° (p < 0.001) and decreased in the control condition from 118.82 ± 4.25 to 117.95 ± 4.29° (p = 0.013). Concentric hamstrings PT and conventional H:Q ratios decreased after both conditions, with smaller decreases after FR (p ≤ 0.05). No significant changes were found for eccentric hamstrings PT, eccentric hamstrings EMG, or functional H:Q ratios (p > 0.05). Foam rolling resulted in greater changes in hamstrings ROM without creating a deficit in PT or muscle activation when compared with the control group. When compared with other methods of stretching, FR may be beneficial in increasing ROM without decreasing functional H:Q ratios.

Øvretveit, K. Anthropometric and physiological characteristics of Brazilian jiu-jitsu athletes.J Strength Cond Res32(4): 997–1004, 2018—The aim of this study was to describe anthropometric and physiological characteristics of Brazilian jiu-jitsu (BJJ) athletes. For this purpose, 42 male athletes were recruited from one of the largest BJJ academies in central Norway. The subjects were 32 ± 6 (SD) years old, 181.9 ± 7.2 cm tall, had a body mass (mb) of 85.7 ± 10.6 kg, and 5.5 ± 3.7 years of BJJ training experience. The subjects underwent segmental multifrequency bioelectrical impedance analysis of body composition (BIA), direct measurements of pulmonary function and maximal oxygen uptake (V̇o2max), assessments of 1-repetition maximum (1RM) in the parallel squat and paused bench press, and one set of pronated-grip pull-ups to muscular failure. The average body fat percentage (BF) was 12.9 ± 5.3%. The subjects achieved a V̇o2max of 50.6 ± 4.6 mL·kg−1·min−1. Absolute squat 1RM (113.2 ± 20.4 kg) was significantly higher than bench press 1RM (87.6 ± 16.5 kg) (p< 0.001). The mean number of pull-ups achieved was 9 ± 4. These characteristics were generally independent of rank, training experience, weekly training volume, competition volume, and style preference. Additional strength training was associated with improved bench press performance (p< 0.05). Beyond that, additional strength and/or conditioning training had no apparent relationship with any variable (p> 0.05). This study provides novel insight into the fitness levels of BJJ athletes. These findings indicate the degree of exercise response to BJJ training and are applicable in athlete assessment and exercise prescription in this population.

Leutzinger, TJ, Gillen, ZM, Miramonti, AM, McKay, BD, Mendez, AI, and Cramer, JT. Anthropometric and athletic performance combine test results among positions within grade levels of high school–aged American football players. J Strength Cond Res 32(5): 1288–1296, 2018—The purpose of this study was to investigate differences among player positions at 3 grade levels in elite, collegiate-prospective American football players. Participants' data (n = 7,160) were analyzed for this study (mean height [Ht] ± SD = 178 ± 7 cm, mass [Bm] = 86 ± 19 kg). Data were obtained from 12 different high school American football recruiting combines hosted by Zybek Sports (Boulder, Colorado). Eight 2-way (9 × 3) mixed factorial analysis of variances {position (defensive back [DB], defensive end, defensive lineman, linebacker, offensive lineman [OL], quarterback, running back, tight end, and wide receiver [WR]) × grade (freshmen, sophomores, and juniors)} were used to test for differences among the mean test scores for each combine measure (Ht, Bm, 40-yard [40 yd] dash, proagility [PA] drill, L-cone [LC] drill, vertical jump [VJ], and broad jump [BJ]). There were position-related differences (p ≤ 0.05) for Ht, 40 yd dash, and BJ, within each grade level and for Bm, PA, LC, and VJ independent of grade level. Generally, the results showed that OL were the tallest, weighed the most, and exhibited the lowest performance scores among positions. Running backs were the shortest, whereas DBs and WRs weighed the least and exhibited the highest performance scores among positions. These results demonstrate the value of classifying high school–aged American football players according to their specific position rather than categorical groupings such as “line” vs. “skill” vs. “big skill” when evaluating anthropometric and athletic performance combine test results.
Development of Processing Map and Constitutive Relationship for Thermomechanical Processing of Aluminum Alloy AA2014
Authors: Narayana Murty S. V. S. , Sarkar Aditya , Ramesh Narayanan P.
Published: February 2018

Isothermal hot compression tests were performed on aluminum alloy 2014 (AA2014) to study the evolution of microstructure over a wide range of temperatures (300°C–500°C) and strain rates (0.001–100 s−1). The true stress–true strain curves obtained at all deformation temperatures and strain rates showed gradual flow softening, which is typical of a dynamic recovery-type material such as aluminum. Processing maps that delineate the stable and unstable regions during hot working were developed and validated by comparing the microstructures recorded in the deformed specimens. Optimum processing conditions (temperature > 450°C, strain rate < 0.1 s−1) for the hot deformation of AA2014 were proposed based on contour maps of efficiency of power dissipation and strain-rate sensitivity parameter. The activation energy value (Qavg) for the hot working of AA2014 was calculated to be 181 kJ/mol−1. Finally, the constitutive equation for the hot working of AA2014 was established.
Recherche-action en contexte de projet plein air interdisciplinaire au primaire : nature des savoirs développés par les praticiens et réflexions méthodologiques

Published: February 2018

Alors que la recherche participative est considérée comme un vecteur de développement professionnel chez les enseignants (Couture, Bednarz et Barry, 2007; Guillemette et Savoie-Zajc, 2012), cet article a pour but d’illustrer la nature des savoirs mobilisés par les praticiens-chercheurs qui se sont engagés dans une recherche-action. Dans un contexte de projet plein air interdisciplinaire, les enseignants et la directrice d’une petite école en région éloignée au Saguenay ont cherché à augmenter le niveau de motivation en lecture des garçons. Par l’intermédiaire de la recherche-action, elles ont dégagé des pistes d’intervention qu’elles ont pu intégrer à leur enseignement, contribuant ainsi à mobiliser des savoirs d’une nature multidimensionnelle, d’origines différentes et qui touchent autant la théorie que la pratique. Les résultats seront discutés, puis suivis d’une réflexion en lien avec le choix méthodologique de la recherche-action et d’un survol de ses retombées.

Au Québec, les fonctions de l’enseignant associé et du superviseur universitaire sont balisées par un référentiel de compétences (Portelance, Gervais, Lessard et Beaulieu, 2008), lequel a fait l’objet d’études (L’Hostie, Cody, Cividini, Allaire et Gauthier, 2008-2011 ; Cody, Cividini et L’Hostie, 2011-2013) démontrant que ces acteurs clés souhaitent collaborer plus efficacement et aider le stagiaire à établir des liens entre les savoirs formels et expérientiels en formation initiale. Afin de répondre à ce besoin, une équipe composée de chercheurs universitaires, d’enseignants associés et de superviseurs universitaires a repensé l’usage du portfolio numérique pour en faire un outil d’accompagnement et de collaboration. Des données issues d’un questionnaire (n = 19) et de deux focus groups (n = 8) ont été analysées du point de vue de la collaboration entre les enseignants associés et les superviseurs universitaires. L’article mettra en lumière les résultats obtenus au terme de deux années d’expérimentation, notamment l’impact du dispositif sur la collaboration entre ces deux catégories d’intervenants.

Published: February 2018

Pour soutenir l’entrée des enseignants dans le monde de l’enseignement en formation professionnelle (FP), les centres de formation professionnelle (CFP) disposent de mécanismes d’accompagnement tels que des structures d’accueil et des systèmes de parrainage (Coulombe, Zourhlal et Allaire, 2010). Malgré tous les mécanismes en place, les nouveaux enseignants continuent à éprouver des besoins de soutien liés à l’apprentissage de leurs tâches de travail. Selon Coulombe, Zourhlal et Allaire (2010), ils ont notamment besoin de comprendre la tâche enseignante, d’être capables de planifier l’enseignement et l’apprentissage, d’être en mesure de gérer les groupes-classes et de soutenir les élèves ayant des besoins particuliers. En collaboration avec des enseignants expérimentés, une conseillère pédagogique et des directions de deux CFP de la région du Saguenay–Lac-Saint-Jean, nous avons donc choisi de mettre à l’essai deux groupes de codéveloppement professionnel (un par CFP participant) pour soutenir les nouveaux enseignants.

Evaluation of real time motion tracking accuracy of customised IMU sensor for application in a mobile badminton virtual reality training system
Authors: Taha Zahari , Wong Mohd Yashim , Yap Hwa Jen , Abdullah Amirul , Yeo Wee Kian
Published: February 2018

Immersion is one of the most important aspects in ensuring the applicability of Virtual Reality systems to training regimes aiming to improve performance. To ensure that this key aspect is met, the registration of motion between the real world and virtual environment must be made as accurate and as low latency as possible. Thus, an in-house developed Inertial Measurement Unit (IMU) system is developed for use in tracking the movement of the player’s racquet. This IMU tracks 6 DOF motion data and transmits it to the mobile training system for processing. Physically, the custom motion is built into the shape of a racquet grip to give a more natural sensation when swinging the racquet. In addition to that, an adaptive filter framework is also established to cope with different racquet movements automatically, enabling real-time 6 DOF tracking by balancing the jitter and latency. Experiments are performed to compare the efficacy of our approach with other conventional tracking methods such as the using Microsoft Kinect. The results obtained demonstrated noticeable accuracy and lower latency when compared with the aforementioned methods.

Published: February 2018

Throwing ball velocity is one of indicator that determines the softball performance. However, most of the training on throwing only focused on the major muscles and they neglected the assisted muscles such as hand grip and trunk rotation muscles that also important in improving the throwing performance. Therefore, the purpose of this study is to identify the effect of hand grip strength training, and trunk rotation strength training towards the throwing ball velocity among female collegiate softball players. 54 female collegiate softball players were equally divided into three training groups which are hand grip strength training group (HG), trunk rotation strength training group (TR), and basic strength training group (CG). All the groups performing the same basic strength training program with different additional strength training according to the group`s treatment. Each group trained 3 days per week for 6 weeks. Throwing ball velocity was assessed before (pretest) and after (posttest) the 6 weeks training program and one-way between groups analysis of variance (ANOVA) was conducted to compare the mean gained score in throwing ball velocity between each group. The result shows that all group significantly differences in throwing ball velocity (p<.05). The post-hoc test indicates that all training group significantly differences to each other except for HG and TR group. This study demonstrates that additional training of HG and TR are able to increase the throwing ball velocity rather than performing the basic strength training only. However, both strength training provides a similar impact on throwing ball velocity, therefore, both of the training are considered important to improve the throwing performance.
Mutational Pleiotropy and the Strength of Stabilizing Selection Within and Between Functional Modules of Gene Expression
Authors: Collet Julie M , McGuigan Katrina , Allen Scott L , Chenoweth Stephen F , Blows Mark W
Published: February 2018

Collet et al. adopt a high-dimensional quantitative genetic approach using gene expression traits to test for the presence of modularity of the genotype-phenotype map, where traits contributing to the same function (functional modularity)...

Variational modules, sets of pleiotropically covarying traits, affect phenotypic evolution, and therefore are predicted to reflect functional modules, such that traits within a variational module also share a common function. Such an alignment of function and pleiotropy is expected to facilitate adaptation by reducing the deleterious effects of mutations, and by allowing coordinated evolution of functionally related sets of traits. Here, we adopt a high-dimensional quantitative genetic approach using a large number of gene expression traits in Drosophila serrata to test whether functional grouping, defined by gene ontology (GO terms), predicts variational modules. Mutational or standing genetic covariance was significantly greater than among randomly grouped sets of genes for 38% of our functional groups, indicating that GO terms can predict variational modularity to some extent. We estimated stabilizing selection acting on mutational covariance to test the prediction that functional pleiotropy would result in reduced deleterious effects of mutations within functional modules. Stabilizing selection within functional modules was weaker than that acting on randomly grouped sets of genes in only 23% of functional groups, indicating that functional alignment can reduce deleterious effects of pleiotropic mutation but typically does not. Our analyses also revealed the presence of variational modules that spanned multiple functions.

OBJECTIVES:

To identify factors associated with longer length of stay (LOS) and higher 30-day hospital revisit rates for children hospitalized with bacterial tracheostomy–associated respiratory tract infections (bTARTIs).

METHODS:

This was a multicenter, retrospective cohort study using administrative data from the Pediatric Health Information System database between 2007 and 2014 of patients 30 days to 17 years old with a principal discharge diagnosis of bTARTI or a principal discharge diagnosis of bTARTI symptoms with a secondary diagnosis of bTARTI. Primary outcomes of LOS (in days) and 30-day all-cause revisit rates (inpatient, observation, or emergency department visit) were analyzed by using a 3-level hierarchical regression model (discharges within patients within hospital).

RESULTS:

We included 3715 unique patients and 7355 discharges. The median LOS was 4 days (interquartile range: 3–8 days), and the 30-day revisit rate was 30.5%. Compared with children 1 to 4 years old, children aged 30 days to 12 months had both longer LOS (adjusted length of stay [aLOS] = +0.9 days; 95% confidence interval [CI]: 0.6 to 1.3) and increased hospital revisit risk (adjusted odds ratio [aOR] = 1.5; 95% CI: 1.3 to 1.7). Other factors associated with longer LOS included public insurance (aLOS = +0.5 days; 95% CI: 0.2 to 0.8), 3 or more complex chronic conditions (CCCs), mechanical ventilation (acute or chronic), and empirical anti-Pseudomonas aeruginosa antibiotics (aLOS = +0.6 days; 95% CI: 0.3 to 0.9). Other factors associated with 30-day revisit included 4 or more CCCs (aOR = 1.3; 95% CI: 1.1 to 1.6) and chronic ventilator dependency (aOR = 1.1; 95% CI: 1.0 to 1.3).

CONCLUSIONS:

Ventilator-dependent patients <12 months old with at least 4 CCCs are at highest risk for both longer LOS and 30-day revisit after discharge for bTARTIs. They may benefit from bTARTI prevention strategies and intensive care coordination while hospitalized.

The teaching and learning process in the mathematics undergraduate program emphasizes on the use of an axiomatic system and formal deduction. In this process, the students learn continuously about mathematical evidence, which can be referred to as the ability to build arguments based on their mathematical understanding. This article aims at describing the characteristics of students' comprehension in constructing a mathematical evidence. A qualitative approach is applied in this study, which involves third-year students of Mathematics Education Department at the state university in Banten. Interviews are conducted to find out and clarify how the students construct and build mathematical evidence. The result shows that the students' mathematical proof of comprehension can be classified into three types: holistic-global, partial-global, and partial-local. It is expected that the result of the study can be used as a source of consideration in determining appropriate learning strategies that can overcome students' difficulties in constructing a mathematical evidence.

An option is a contract between a holder and a writer in which the writer grants the rights (not obligations) to the holder to buy or sell the assets of the writer at a certain price (strike price) at maturity time. Asian options are included in the dependent path option. This means that Asia's payoff option depends not only on the stock price at maturity time, but it is the average stock price during its maturity and symbolized A (average). Monte Carlo is basically used as a numerical procedure to estimate the expected value of pricing product derivatives. The techniques used are the standard Monte Carlo and variance reduction. The result obtained the Asia call option price and put for both techniques with 95% confidence interval. The variance reduction technique looks faster reducing 95% confidence interval than standard method.

The hygienic properties of lining leathers can be improved significantly by introducing oregano essential oil into leathers. This is because adding antiseptic oil makes leathers more resistant to microorganisms that are potentially harmful to humans and cause damage to animal leathers. The paper presents the results of tests to check selected mechanical properties – tensile strength, elongation and tear load – of leathers fatliquored with oregano essential oil at a concentration of 3% w/w and without this treatment. The tests were carried out on the Instron 5544 testing machine.The leathers enriched with oil met the standard requirements set for lining leathers for of the parameters: tensile strength and elongation. Statistical analysis using the chi-squared, Hartley and Fisher-Snedecor tests at an assumed significance level of α = 0.05 revealed that leather enriched with oregano essential oil has a significantly higher tensile strength than leather fatliquored without this oil, while both leather samples showed no significant difference in elongation and tear load. Thus, it can be concluded that adding 3% w/w of oil will have not have an adverse effect on basic mechanical properties of leathers.

The objective of this research project was to determine the effect of high temperatures and UV irradiation on the dynamics of oxidation of selected cold-pressed oils. The composition of fatty acids in the oil samples and their characteristic numbers were determined. The oil samples were heated to temperatures of: 80, 100 and 110ºC without irradiation, and after UV irradiation. Measurements of the peroxide value during heating were used to determine the oxidation changes. It was determined that that value rose along with the temperature. The processes studied were characterised by varying dynamics, a fact confirmed by the values of rate constants and the ratios of these rate constants for comparable processes. Stability periods were calculated for oil samples heated at the three temperatures, and subjected to UV irradiation prior to heating. The tests demonstrated that both an increase in temperature and irradiation result in the oils having a clearly shorter stability period.
