Sagittal and Frontal Plane Gait Initiation Kinetics in Healthy, Young Subjects
Authors: Smith Andrew W. , Wong Del P. 
Published: July 2019

Abstract
The study purposes were to record the lower extremity sagittal and frontal joint moments and powers during gait initiation (GI); evaluate GI support moments in both planes; and analyze planar energy patterns in a group of 15 healthy, young adults. 3D motion and ground reaction force data were used to calculate support moments (SM) and joint moments and powers as well as center of mass (COM) kinematics. STEP1 had no visible SM. It appeared in STEP2 and, by STEP3, resembled that seen in steady-state gait. Joint moments demonstrated a similar development towards typical patterns over the three steps. Correlations of moment data between planes indicate that the frontal plane component of the SM acts to keep the COM centered. It is suggested that Winter’s 1980 SM definition be extended to include both a support (sagittal) component and a centering (frontal) component. Energy was calculated for individual bursts of joint powers in both planes and each step had characteristic patterns in each plane, with patterns resembling steady-state gait appearing in the third step. Test-retest reliability (ICC range: 0.796 – 0.945) was high with CV values in the sagittal plane (36.6 – 37.5%) being less variable than in the frontal plane (39.0 – 82.0%). COM kinematics revealed that acceleration peaked in STEP2 (ICC range: 0.950 – 0.980, CV < 20.0%). Data supported hypotheses regarding the dominance of the frontal plane power in STEP1, with substantial power coming from hip flexors. As well, powers in the sagittal plane were generally of larger magnitude than in the frontal plane.

Abstract
The purpose of this study was to evaluate the reliability and reproducibility of the physiological and overload features of the Yo-Yo intermittent endurance test level 2 (Yo-Yo IE2) in competitive male soccer (n = 20), basketball (n = 11), and volleyball players (n = 10). The participants completed Yo-Yo IE2 tests on three separate occasions with assessment of performance, heart rate, running speed, accelerations, decelerations and body load using GPS instrumentation. The intra-class correlation coefficient index, confidence intervals and coefficients of variation were calculated to assess the reliability of the test. Intra-class correlation coefficients for test-retest trials in the total sample ranged from large to nearly perfect (total distance: 0.896; mean speed: 0.535; maximum speed: 0.715; mean HR: 0.876; maximum HR: 0.866; body load: 0.865). The coefficients of variation for distance, mean speed, HR response, as well as acceleration and deceleration scores for test-retest trials ranged from 1.2 to 12.5% with no differences observed among particular sport disciplines. The CV for shuttles performed ranged from 4.4 to 5.5% in all sports. Similar results were obtained for the three different categories of players tested. These results suggest that the Yo-Yo IE2 test appears to be a reliable alternative for evaluating the ability to perform intermittent high-intensity running in different outdoor and indoor team sports. Players may need one or two familiarization tests to ensure valid assessment of intermittent endurance capacity. It appears that the Yo-Yo IE2 test incorporates accelerations and decelerations in a consistent and reproducible fashion.

Authors: Zhang Shen , Fu Weijie , Liu Yu 
Published: July 2019

Abstract
We aimed to explore the biomechanical differences between the anticipated drop jump and unanticipated drop landing. Twelve male collegiate basketball players completed an anticipated drop jump and unanticipated drop landing with double legs from a height of 30 cm. Kinematics, impact force, soft tissue vibrations, and electromyographic (EMG) amplitudes of the dominant leg were collected simultaneously. The anticipated drop jump showed more flexed lower limbs during landing and increased range of motion compared to the unanticipated drop landing. The anticipated drop jump also had lower impact force, lesser soft tissue vibration, and a greater damp coefficient at the thigh muscles compared with the unanticipated drop landing. Significant increases in the EMG amplitudes of the tibialis anterior, lateral gastrocnemius, rectus femoris, and biceps femoris were observed in the anticipated drop jump during the pre/post-activation and downward phases. The anticipated drop jump presented more optimized landing posture control with more joint flexion, lower impact force, less soft tissue vibrations, and full preparation of muscle activations compared with the unanticipated drop landing.
Electrical Storm Due to Active Myocardial Ischemia in the Right Coronary Artery Territory – Case Report
Authors: Păsăroiu Dan , Parajkó Zsolt , Mitra Noémi , Opincariu Diana 
Published: July 2019

Abstract
Electrical storm is defined by at least three episodes of sustained ventricular tachyarrhythmias or appropriate shocks given by implantable cardiac defibrillator devices (ICD), occurring within a period of 24 hours. In the present manuscript, we present the case of a 69-year-old female patient with previous aortocoronary bypass, who was admitted from the Emergency Department after presenting several episodes of syncope in prehospital settings and presented 4 episodes of sustained ventricular tachycardia which required electrical cardioversion. The arrhythmia disappeared after percutaneous revascularization of a chronic occlusion in the right coronary artery. In this case, the implantation of an ICD was avoided, as a reversible cause of ES has been identified and treated.

Published: July 2019

Abstract
Mangroves critically require conservation activity due to human encroachment and environmental unsustainability. The forests must be conserving through monitoring activities with an application of remote sensing satellites. Recent high-resolution multispectral satellite was used to produce Normalized Difference Vegetation Index (NDVI) and Tasselled Cap transformation (TC) indices mapping for the area. Satellite Pour l’Observation de la Terre (SPOT) SPOT-6 was employed for ground truthing. The area was only a part of mangrove forest area of Tanjung Piai which estimated about 106 ha. Although, the relationship between the spectral indices and dendrometry parameters was weak, we found a very significant between NDVI (mean) and stem density (y=10.529x + 12.773) with R2=0.1579. The sites with NDVI calculated varied from 0.10 to 0.26 (P1 and P2), under the environmental stress due to sand deposition found was regard as unhealthy vegetation areas. Whereas, site P5 with NDVI (mean) 0.67 is due to far distance from risk wave’s zone, therefore having young/growing trees with large lush green cover was regard as healthy vegetation area. High greenness indicated in TC means, the bands respond to a combination of high absorption of chlorophyll in the visible bands and the high reflectance of leaf structures in the near-infrared band, which is characteristic of healthy green vegetation. Overall, our study showed our tested WV-2 image combined with ground data provided valuable information of mangrove health assessment for Tanjung Piai, Johor, Malay Peninsula.
Industrial clusters in a post-socialist country: The case of the wine industry in Slovakia
Authors: Novotná Jana , Novotný Ladislav 
Published: July 2019

Abstract
Research on clusters, unlike cluster initiatives, has not been comprehensively addressed in European post-socialist countries. The aim of this paper is to explore and to analyse quantitatively the spatial organisation of economic activities in the wine industry in Slovakia, and to assess it in terms of the concept of an industrial cluster. The wine industry is considered as a production sector in which location is determined by geographical factors. The research is based on a case study of a wine region located north-east of Bratislava, Slovakia. The primary identification of the cluster potential is based on the assessment of geographic conditions and statistical analyses focused on the spatial concentration of the industry within the defined area. An extensive questionnaire survey provided data for assessing the spatial organisation of economic activities and their impact on regional competitive advantage. Despite the spatial distribution of economic activities and relations among business entities affected by socialist industrialisation and post-socialist transformation, the results show that the industrial cluster was formed in the wine industry and its performance converges with the wine clusters in traditional Western European wine regions.
Reinventing Organizations: Model of Self-Organized Process Organization (SOPO)
Authors: Kopina Dmitriy 
Published: July 2019

Abstract

Background and Purpose: Self-organization in teams and Business Process Orientation have been subjects of many separate researches, yet there is lack of research actually joining it within a common research. The purpose of our research is to define a research model for new type of service organization - called SOPO (Self-Organised Process Organization). This model sets research base to determine SOPO’s maturity level and a self-assessment tool, helping new emergence or transitions of existing organization toward SOPO.

Methodology: We conducted a case researches in three ICT service companies, which were undergoing a transition process towards SOPO. We conducted several in-depth, un-structured and structured part of interviews with employees holding three different positions in each organization. Hereby we present the researched organisation with most explicit case.

Results: We defined the key elements of the model and tested it in a case research. Key elements are Self-Organised Work Teams (SOWT) and Business Process Orientation (BPO). Both SOWT and BPO are positively affecting level of SOPO. Level of SOPO is positively related to both, enthusiasm of personnel to work in self-organised environment and perceived Quality of Service (QS).

Conclusion: SOPO model can be used: (1) in existing companies as a blueprint for SOPO implementation, (2) to assess the maturity level of companies reinventing their organizational structure, and (3) helping SOPO organizations to structure changes toward higher service quality. SOPO model is a viable starting point in further research. Further verification of the SOPO model by a quantitative research is needed.
Current Trends in Slovak Legislation Regulating Renewable Energy Production
Authors: Beňuš Ondrej , Čeryová Dominika 
Published: July 2019

Abstract
Renewable energy production is one of key actions undertaken by the EU to lower its dependency on energy imports from third countries. Renewable energy is not competitive compared to fossil fuels at this moment. Under these circumstances, there is a need for an effective legal regulation. The EU has set main targets relating renewable energy use in the directive (EU) 2018/2001. Slovak policymakers have recognized these new targets. The main objective of the paper is to examine the latest changes to the Slovak legal regulation of the renewable energy production with focus on electricity production. We analyse changes made by the amendment of the Act No. 309/2009 Coll. and provide a short explanation of new instruments.
Attitude-Behaviour Gap Among Polish Consumers Regarding Green Purchases
Authors: Witek Lucyna 
Published: July 2019

Abstract
The purchasing behaviour in the market of green products is at a low level. Consumers express their concern about the future of the planet and the cleanliness of the environment, but in their conduct they do not take into account ecological criteria. There is a discrepancy between what consumers say and what they really do. A favourable attitude to the idea of environmental protection does not translate into real action. The reasons for this gap have not been sufficiently researched yet. The aim of the research is to identify the causes of attitude-behaviour gap in the market of environmentally friendly products in Poland. To achieve the goal, the desk research and surveys were applied. The research shows that green products are well evaluated by consumers, although the knowledge about them is general and partial. Only 21% of respondents indicate knowledge of the production process, certification and control of environmentally friendly products. A large group of surveyed consumers (43%) shows willingness to pay higher prices for environmentally friendly products. But only one third of respondents (32%) declares trust in such products.
The Extended Functions of Strategic Controlling in Relation to the Value Creation of Sustainable Development
Authors: Zéman Zoltán 
Published: July 2019

Abstract
Strategic planning is generally performed internally and particularly by the organization. Another, lesser discussed issue of non-adequate strategic planning is that corporate management is unable to outline its long term resources without it. Supporting and ensuring the feasibility of individual set-ups of this function, which is probably the most important of all, is without doubt an expanded task of strategic control. From the managers’ point of view, the time spent on managing and controlling the individual tasks is also a type of resource to be managed. The strategy is the subject of development on a regular basis – that is, also an expanded task of strategic control – and managers should always take it into consideration alongside the operational tasks, since the design, development and implementation of strategy are affected by high-risk events of the external environment. The mapping of sustainable development at the microeconomic level is part of corporate social responsibility. Sustainable development requires global thinking and action. This is reflected in the fact that, in their economic decisions, businesses should strive for the economical use of scarce resources, achieve a balance between resource development and preservation, and ensure an appropriate dialogue, the so-called “resource” of stakeholders. The aim of the paper is to demonstrate the role of controlling in sustainable development using theoretical modelling.

Background Structural abnormalities associated with osteoarthritis (OA) are found in some patients with patellofemoral pain (PFP). Objectives To investigate the association between early signs of OA on magnetic resonance imaging (MRI) and characteristics from self-reported measures and physical examination in patients with PFP. Methods This exploratory study included data from patients with PFP from a previously published cross-sectional case-control study (n = 64; 55% female; mean ± SD age, 23.4 ± 7.0 years). Structural OA features (osteophytes, bone marrow lesions, cartilage defects, Hoffa synovitis, patellar tendon abnormalities) and quantitative T2 measurements of cartilage composition were extracted from MRI. Associations between characteristics from self-reported measures (pain at rest, pain during stair walking, knee function, duration of complaints, hours of sports participation each week), physical examination (crepitus, quadriceps strength), and early MRI signs of OA were assessed. Results Symptom duration was associated with bone marrow lesions in the patella (odds ratio [OR] = 1.1; 95% confidence interval [CI]: 1.0, 1.2). Sports participation (hours per week) was inversely associated with patellar tendon abnormalities on MRI (OR = 0.8; 95% CI: 0.6, 1.0). Crepitus and bilateral nature of the complaints were associated with minor patellar cartilage defects (OR = 12.0; 95% CI: 2.3, 63.6 and OR = 7.6; 95% CI: 1.1, 53.8, respectively). There were no significant associations between clinical characteristics and cartilage T2 relaxation time. Conclusion Presence of crepitus, bilateral complaints, a long PFP symptom duration, and reduced weekly sport participation were associated with early signs of OA in a young PFP population.

Resorcinarene Cavitand Polymers for the Remediation of Halomethanes and 1,4-Dioxane
Authors: Skala Luke , Yang Anna , Klemes Max Justin , Xiao Leilei , Dichtel William 
Published: July 2019

Executive summary: Porous resorcinarene-containing polymers are used to remove halomethane disinfection byproducts and 1,4-dioxane from water.Disinfection byproducts such as trihalomethanes are some of the most common micropollutants found in drinking water. Trihalomethanes are formed upon chlorination of natural organic matter (NOM) found in many drinking water sources. Municipalities that produce drinking water from surface water sources struggle to remain below regulatory limits for CHCl3 and other trihalomethanes (80 mg L–1 in the United States). Inspired by molecular CHCl3⊂cavitand host-guest complexes, we designed a porous polymer comprised of resorcinarene receptors. These materials show higher affinity for halomethanes than a specialty activated carbon used for trihalomethane removal. The cavitand polymers show similar removal kinetics as activated carbon and have high capacity (49 mg g–1 of CHCl3). Furthermore, these materials maintain their performance in real drinking water and can be thermally regenerated under mild conditions. Cavitand polymers also outperform activated carbon in their adsorption of 1,4-dioxane, which is difficult to remove and contaminates many public water sources. These materials show promise for removing toxic organic micropollutants and further demonstrate the value of using supramolecular chemistry to design novel absorbents for water purification.
Eppur Si Riscalda - and yet, It (Just) Heats Up: Further Comments on “Quantifying Hot Carrier and Thermal Contributions in Plasmonic Photocatalysis”
Authors: Sivan Yonatan , Baraban Joshua H. , Dubi Yonatan 
Published: July 2019

Our Comment [1] on recent attempts to distinguish thermal and non-thermal (``hot carrier'') contributions to plasmon-assisted photocatalysis [2] initiated a re-evaluation process of previous literature on the topic within the nano-plasmonics and chemistry communities. The Response of Zhou et al [3] attempts to defend the claims of the original paper [2].In this manuscript, we show that the Response [3] presents additional data that further validates our central criticism: inaccurately measured temperatures (that are lower than the actual temperature of the catalyst) led Zhou \etal to incorrectly claim conclusive evidence of non-thermal effects. We identify flaws in the experimental setup (e.g. the use of the default settings for the thermal camera and incorrect positioning of the thermometer) that may have led Zhou et al to make such claims. We further show that the Response contains several factual errors and does not address the technical problems we identified with the data acquisition in [2]. We demonstrate that both the Response [3] and the original paper [2] contain additional faults, for example, in the power determination and in the normalization of the rate to the catalyst volume, and exhibit misconceptions regarding the thermo-optic response of metal nanostructures. The burden of proof required by the proposal of a novel physical mechanism has simply not been met, especially when the existing data can be modeled exquisitely by conventional theory.[1] Y.

Skinny, Slim, dan Thin: Analisis Berbasis Korpus Kata Sifat Identik dan Implikasinya pada Pengajaran Bahasa Inggris
Authors: Islamiyah Millatul , Fajri Muchamad Sholakhuddin Al 
Published: July 2019

This paper is an exploratory corpus-based investigation into a group of near synonymous adjectives: skinny, slim, and thin. It employs the British National Corpus (BNC) as data and Sketch Engine as data analysis instrument. By using corpus linguistics techniques such as concordance and collocation analysis, it compares the synonymous words’ usage, meaning, and pattern to identify which synonymous words are more appropriate in a certain context. The results suggest that thin has neutral nuance expression and slim tends to carry positive connotation, while skinny is often used by speakers when they want to be more pejorative or deprecating. Moreover, unlike skinny which mainly modifies animate-related nouns, slim is more heterogeneous as they also can modify inanimate-related nouns and when it collocates with inanimate nouns, it often extends its’ meaning into metaphor expression which means ‘small’. Thin is used in many idiomatic expressions and when combined with common words it can also be used to denote metaphorical meaning. These findings can be applied in English language teaching so that students will be able to use the synonymous adjectives in an apt context and to avoid undesirable implication. ABSTRAKPenelitian ini adalah analisis berbasis korpus pada kelompok kata sifat yang hampir sama: “skinny”, “slim”, dan “thin”. Penelitian ini menggunakan British National Corpus (BNC) sebagai data dan Sketch Engine sebagai instrumen analisis data. Dengan menggunakan teknik linguistik korpus seperti konkordansi dan analisis kolokasi, artikel ini membandingkan penggunaan, makna, dan pola kata sinonim untuk mengidentifikasi kata-kata sinonim yang lebih tepat dalam konteks tertentu. Hasilnya menunjukkan bahwa “thin” memiliki ekspresi nuansa netral dan “slim” cenderung membawa konotasi positif, sementara “skinny” sering digunakan oleh pembicara ketika mereka ingin lebih merendahkan atau mencela. Selain itu, tidak seperti “skinny” yang banyak memodifikasi nomina yang berhubungan dengan benda hidup, “slim” lebih heterogen karena mereka juga dapat memodifikasi nomina yang tidak hidup dan ketika ia bertaut dengan kata benda tak hidup, ia sering memperluas maknanya menjadi ekspresi metafora yang berarti “small”/kecil. “Thin” digunakan dalam banyak ekspresi idiomatis dan ketika dikombinasikan dengan kata-kata umum, “thin” juga dapat digunakan untuk menunjukkan makna metaforis. Temuan ini dapat diterapkan dalam pengajaran bahasa Inggris sehingga siswa akan dapat menggunakan kata sifat sinonim dalam konteks yang tepat dan untuk menghindari implikasi yang tidak diinginkan.
