Causes of Accident at Construction Sites in Bangladesh
Authors: Ahmed Shakil 
Published: June 2019

Abstract
Bangladeshi construction industry suffers more safety issues than other developing countries in the world. Among many of these, accidents at the construction site go far beyond and shape a horrific figure of death every year. The aims of this study are to identify and prioritize the causes of accidents. This study also analyses and discusses causes of accident at the construction site in Bangladesh. A widespread literature review and open discussion took place to identify the causes and design the questionnaire. The questionnaire-based survey was used to elicit the attitude of four stakeholders such as workers, owners, consultants and contractors towards the causes of accident. Mean and relative importance index (RII) were used to determine the rank of causes, and Statistical Package for the Social Sciences (SPSS) 23 was used to perform the data validation test. This study identifies 77 causes under 14 major groups and ranked them based on the mean and RII. The top five major groups of causes are management-, consultant-, technology-, labour- and contractor-related causes. The top five causes are unawareness of safety-related issue, lack of personal protective equipment, lack of safety eliminating/avoiding design, unfit equipment, lack of knowledge and training on equipment. This study will help the project participants and authorities to know and understand the various characteristics and linkage of causes of construction accidents to improve the construction safety management. It contributes to the body of knowledge, as it reveals for the first time the causes of accidents in the Bangladeshi construction industry.
The Agon Motif and the Concept of Movement Culture
Authors: Renson Roland 
Published: June 2019

Abstract
At a symposium on 12 June 2009 on “Homo Movens: International symposium on movement culture” at the occasion of my ‘rite of passage’ to the emeritus status at the KU Leuven, John W. Loy, co-authored by W. Robert Morford, presented a paper on “The agon motif: A study of the contest element in sport”. I am very glad that this excellent paper will finally be published as it was not included in “The making of sport history: Disciplines, identities and the historiography of sport” (Delheye 2014), which appeared five years later as a so called “…crystallization of the international symposium.” (p. XVII). Moreover, some of these contributions were severely criticized by Allen Guttmann (2014).
In this introduction, I will try to clarify the concepts of ‘ludodiversity’ and ‘movement culture’, which I have often had the chance to discuss with John Loy personally. We did – of course – not always agree but this kind of ‘joking relationship’ with John Loy was and still is for me a “… joy forever”!
Analysis of Direct Torque Control with pace Vector Modulation for Synchronous Reluctance Motor Motion Control Applications and a Comparison with Other Torque-Control Algorithms
Authors: Vajsz Tibor , Számel László , Handler Árpád 
Published: June 2019

Abstract
Motion control is facing an increasing popularity in the present research activities. Owing to the expected wide spreading of motion control applications, it can be predicted that the advancements in the field of electric motor drives will have a high level of influence on the new results in the field of motion control. The synchronous reluctance motor drives mean an excellent and yet cost-effective solution for actuators in motion control applications. In this article, the direct torque control with space vector modulation is analysed as a possible candidate for synchronous reluctance motor motion control applications. Its torque-control performance is investigated as a function of torque-control sample time, and a comparison of the torque ripples is made with other torque-control algorithms by an FFT analysis.
The use of high-frequency short bipolar pulses in cisplatin electrochemotherapy in vitro
Authors: Scuderi Maria , Rebersek Matej , Miklavcic Damijan , Dermol-Cerne Janja 
Published: June 2019

Abstract

Background
In electrochemotherapy (ECT), chemotherapeutics are first administered, followed by short 100 μs monopolar pulses. However, these pulses cause pain and muscle contractions. It is thus necessary to administer muscle relaxants, general anesthesia and synchronize pulses with the heart rhythm of the patient, which makes the treatment more complex. It was suggested in ablation with irreversible electroporation, that bursts of short high-frequency bipolar pulses could alleviate these problems. Therefore, we designed our study to verify if it is possible to use high-frequency bipolar pulses (HF-EP pulses) in electrochemotherapy.

Materials and methods
We performed in vitro experiments on mouse skin melanoma (B16-F1) cells by adding 1–330 μM cisplatin and delivering either (a) eight 100 μs long monopolar pulses, 0.4–1.2 kV/cm, 1 Hz (ECT pulses) or (b) eight bursts at 1 Hz, consisting of 50 bipolar pulses. One bipolar pulse consisted of a series of 1 μs long positive and 1 μs long negative pulse (0.5–5 kV/cm) with a 1 μs delay in-between.

Results
With both types of pulses, the combination of electric pulses and cisplatin was more efficient in killing cells than cisplatin or electric pulses only. However, we needed to apply a higher electric field in HF-EP (3 kV/cm) than in ECT (1.2 kV/cm) to obtain comparable cytotoxicity.

Conclusions
It is possible to use HF-EP in electrochemotherapy; however, at the expense of applying higher electric fields than in classical ECT. The results obtained, nevertheless, offer an evidence that HF-EP could be used in electrochemotherapy with potentially alleviated muscle contractions and pain.

Published: June 2019

Abstract

Background
Repeated haemarthroses affect approximately 90% of patients with severe haemophilia and lead to progressive arthropathy, which is the main cause of morbidity in these patients. Diagnostic imaging can detect even subclinical arthropathy changes and may impact prophylactic treatment. Magnetic resonance imagining (MRI) is generally the gold standard tool for precise evaluation of joints, but it is not easily feasible in regular follow-up of patients with haemophilia. The development of the standardized ultrasound (US) protocol for detection of early changes in haemophilic arthropathy (HEAD-US) opened new perspectives in the use of US in management of these patients. The HEAD-US protocol enables quick evaluation of the six mostly affected joints in a single study. The aim of this prospective study was to determine the diagnostic accuracy of the HEAD-US protocol for the detection and quantification of haemophilic arthropathy in comparison to the MRI.

Patients and methods
The study included 30 patients with severe haemophilia. We evaluated their elbows, ankles and knees (overall 168 joints) by US using the HEAD-US protocol and compared the results with the MRI using the International Prophylaxis Study Group (IPSG) MRI score.

Results
The results showed that the overall HEAD-US score correlated very highly with the overall IPSG MRI score (r = 0.92). Correlation was very high for the evaluation of the elbows and knees (r ≈ 0.95), and slightly lower for the ankles (r ≈ 0.85).

Conclusions
HEAD-US protocol proved to be a quick, reliable and accurate method for the detection and quantification of haemophilic arthropathy.

Authors: Neverauskaitė-Piliponienė Gintarė , Kūgienė Rasa , Petrulionienė Žaneta , Šerpytis Pranas 
Published: June 2019

Summary
Right ventricular myocardial infarction (RVMI) accompanies about 30–50% of inferior wall myocardial infarction. RVMI is associated with higher rates of cardiogenic shock, atrioventricular block, atrial fibrillation, increased mortality rates. The topic requires a scientific update, as only a few studies have been made on RVMI during the past decade. We aimed to analyse the impact of RVMI on inferior myocardial infarction.

Design and methods: Retrospective study included 310 patients with documented inferior myocardial infarction (with and without RVMI) between January 2013 and January 2014. Data on baseline characteristics, mortality, in-hospital complications: cardiogenic shock and rhythm and conduction disorders was collected.

Results: In 102 (32.9%) patients with inferior myocardial infarction, RVMI was present and 208 (67.1%) cases were without RVMI involvement. RVMI patients had higher rate of rhythm and conduction disturbances than patients without RVMI involvement: atrioventricular block (OR 3.8, 95% CI 2.0–7.1, p < 0.001), atrial fibrillation (OR 1.6, 95% CI 0.9–2.9, p = 0.001), also higher incidence of cardiogenic shock (OR 2.6, 95% CI 1.7–3.9, p < 0.001). Mortality rates after 24 months were higher in RVMI group (OR 1.8, 95% CI 1.2–3.8, p = 0.034). No significant difference was found on in-hospital mortality.

Conclusions: Right ventricular involvement complicates the long-term mortality and outcomes after inferior myocardial infarction. It is related to a higher incidence of in-hospital complications, especially I–III degree AV block and atrial fibrillation. However, influence on long-term mortality needs further investigation.
The Possibility of Ultraviolet Enceladus’ Observations from Stratospheric Balloons
Authors: Kotlarz Jan , Zalewska Natalia 
Published: June 2019

Abstract
Stratospheric balloons are very important sources for space and terrestrial observation experiments in many disciplines. Instruments developed for astrophysical measurements are usually reusable. It is also possible to observe both hemispheres including observations from the polar and equatorial regions for thirty days or even longer. On the other hand the UV atmospheric transmittance window was used for the astrophysical observations less often than visible optical bands. At the end of the 2017 there are a few scientific groups working on near-UV or UV spectrographs and cameras for balloon flights.
In this paper we are discussing the possibility of ultraviolet measurement of Enceladus, an icy Saturnian moon, surface reflectance between 200 and 400 nm from the 20-50 km altitudes. At visible and near infrared optical channels Enceladus’ reflectance is very high (near 1.0). This value is consistent with a surface composed of water ice, however at some ultraviolet wavelengths Enceladus reflectance is lower than it would be expected for this type of surface. The scientific research done in the last decade was focused on H2O, NH3, and tholin particles detection on the Enceladus’ surface as a reason of low UV reflectance phenomenon. Continuous observation of Enceladus’ UV reflectance variability from stratospheric balloons may be interesting and may give us the proof of the presence of biomarkers or/and tholin particles.
Estimation of an Airfoil Drag at High Angles of Attack from PIV Data
Authors: Karr Austin M. , Stryczniewicz Wit 
Published: June 2019

Abstract
The paper presents application of Particle Image Velocimetry for determination of an airfoil’s drag coefficient in wind tunnel tests. The purpose of the study was to investigate the feasibility of using PIV as an alternative to pressure rake measurements, especially at high angles of attack. The integral momentum concept was applied for determination of fluid drag from experimental low speed wind tunnel data. The drag coefficient was calculated from velocity and pressure rake data for intermediate angles of attack from 5° to 10°. Additionally, the experimental results were compared to panel method results. After validating the procedures at low angles of attack, the drag coefficient was calculated at close to critical angles of attack. The presented study proved that PIV technique can be considered as an attractive alternative for drag coefficient determination of an airfoil.

Authors: Rahmiwati Anita 
Published: June 2019

Feeding or eating good upbringing which affects the development growth and intelligence of children. For that it is necessary feeding patterns or parenting eat right and balanced in order to stay healthy and avoid infection or other diseases related to nutrition. A balanced diet is eating according to composition of food that our body needs in portions adapted to needs of children at each age. Respondents in this study are the parents of kindergarten children Rabbani North Indaralaya with range of aged 4-6 years. Implementation of FGD was attended by 12 people, consisting; three researchers, two minutes, and seven respondents. Respondents selected through purposive sampling, based on predetermined criteria and is considered capable of answering research problems. The purpose of study is to explore more deeply about parenting feeding mothers in Ogan Ilir associated with understanding (the concept of balanced nutrition, quantity of feeding practices in terms, frequency, form, variety and type of food). This study used a qualitative approach. The data collection technique are Focus Group Discussion. Data processing was done manually using content analysis method (analysis). The results showed majority of mothers do not understand that concept of balanced nutrition, for this aspect the number of feeding infants in Ogan Ilir still do not meet the nutritional needs to children as seen from the children often do not prepared food to consume by their mother if the child does not like the dishes being served. From the aspect of the frequency almost mothers only give meal 2-3 times and 1 times a additional food during the day. From this aspect of mother form has given the same food with family to meal but this menu give only food in like a child. In terms of variety of food provided to children are still less and almost children do not consume vegetables and fruit. Mother feeding patterns in children is not good, lack of parental support in providing food resulted in children accustomed to eating that is not good. Appropriate educational media is required age of children to increase the child's knowledge about nutritious food and motivate children to want to eat nutritious food.

Published: June 2019

Мета. Визначення способу хірургічного лікування спонтанних внутрішніх біліарних нориць (СВБН) при синдромі Mirizzi (СМ).
Матеріали і методи. Ретроспективно проаналізовано результати лікування 8000 пацієнтів із жовчнокам’яною хворобою в Закарпатській обласній клінічній лікарні імені Андрія Новака з 1997 по 2017 р. У 192 із цих пацієнтів спостерігали СВБН. Отже, частота виявлення СВБН становила 2,4%.
Результати. При СМ І типу виконували холецистектомію із зашиванням широкої і короткої міхурової протоки, ІІ типу - холецистектомію «від дна» з висіченням норицевого ходу і зашиванням дефекту у загальній жовчній протоці (ЗЖП) на Т-подібній трубці, ІІІ типу - холецистектомію з пластикою ЗЖП залишками стінки жовчного міхура і зовнішнім дренуванням Т-подібною трубкою, IV типу - холецистектомію «від дна» із повним пересіченням ЗЖП. У 19 хворих із холедоходуоденальними норицями при СМ І типу виконали ендоскопічну папілофістулотомію із метою надійного дренування ЗЖП, евакуції конкрементів із неї і ліквідації внутрішнього отвору нориці.
Висновки. Метою операції при СВБН є видалення жовчного міхура, забезпечення відтоку жовчі у просвіт травного каналу і пасажу хімусу по ньому. Якщо норицю у порожнистому органі, виконують її висічення з ушиванням отвору, в окремих спостереженнях застосовують резекційні способи ліквідації нориць.

Мета. Вивчити частоту папілярних карцином щитоподібної залози з різними характеристиками в залежності від віку пацієнтів з урахуванням дати їх народження - до та після аварії на Чорнобильській АЕС.
Матеріали і методи. Проведено ретроспективне дослідження щодо 4956 пацієнтів, оперованих з приводу папілярної карциноми щитоподібної залози в 1995 - 2014 рр.
Результати. Найчастіше пухлини розміром 21 - 40 мм, категорії N1ab і М1, з інвазією в капсулу пухлини, інтра- чи екстратиреоїдною інвазією спостерігали у пацієнтів у віці до 18 років у порівнянні з дорослими пацієнтами, незважаючи на дату їх народження. У дітей та підлітків, народжених після аварії, рідше, ніж у дітей та підлітків, народжених до аварії, реєстрували мультифокальні карциноми та карциноми категорії N1ab.
Висновки. Папілярні карциноми у дітей та підлітків, які народилися до та після аварії на Чорнобильській АЕС, є агресивнішими за папілярні карциноми у дорослих пацієнтів, проте за своїми клінічними характеристиками вони не відрізняються між собою, за винятком меншої частоти мультифокальних карцином і карцином категорії N1ab.
