Published: September 2021

Abstract
Myocardial ischemia is a metabolic phenomenon that occurs in patients undergoing open heart surgery like coronary artery bypass grafting (CABG), valvular heart surgery, vascular surgeries etc., due to stress imposed during cardiopulmonary bypass (CPB), obligatory interruption of coronary blood flow during aortic cross clamp and reperfusion after aortic cross clamp release. The present study is designed to have a detailed study on estimation of coronary sinus lactate and troponin t levels in patients undergoing cardiac surgery with cardiopulmonary bypass and its correlation with various parameters related to the perioperative outcomes.
A Hybrid and Robust Delay and Link Stability Aware (DLSA) Routing Protocol for Unmanned Aerial Ad-hoc Networks (UAANETs)
Authors: Hussain Altaf 
Published: September 2021

Abstract
Unmanned Aerial Ad-hoc Network (UAANET) also knows as by the name of Flying Ad-hoc NETwork (FANET) is a new class of Mobile Ad-hoc NETwork (MANET) in which the nodes move in three dimensional (3-D) ways in the air simultaneously. These nodes are known as Unmanned Aerial Vehicles (UAVs) that are operated live remotely or by pre-defined mechanism which involve no human personnel. Due to high mobility of nodes and dynamic topology, the link stability is a research challenge in FANET. From this viewpoint, recent research has focused on link stability with highest threshold value by maximizing Packet Delivery Ratio (PDR) and minimizing End-to-End Delay (E2ED). In this research, a hybrid scheme named Delay and Link Stability Aware (DLSA) routing scheme has been proposed with the contrast of Distributed Priority Tree-based Routing (DPTR) and Link Stability Estimation-based Routing (LEPR) FANET’s existing routing schemes. Unlike existing schemes, the proposed scheme possesses the features in collaborative data forwarding and link stability by merging the positive features of DPTR and LEPR. The link stability via maximum threshold value has been introduced to acquire and select the most feasible route from source to destination. The simulation was carried out using Matrix Laboratory (MATLAB) tool for the concerned research. Simulation results have showed improved performance of the proposed protocol in contrast to the selected existing ones in terms of E2ED, PDR, Network Lifetime and Transmission Loss. Average E2ED in (milliseconds) of DLSA measured 0.457, while DPTR was 1.492 and LEPR was 1.006. Similarly, Average PDR (in %age) of DLSA measured 3.106, while DPTR was 2.303 and LEPR was 0.682. Average Network Lifetime in (seconds) for DLSA measured 62.141, while DPTR was 23.036 and LEPR was 27.298. Average Transmission Loss in (dBm) for DLSA measured 0.975, while DPTR was 1.053 and LEPR was 1.227.

Abstract
PURPOSE:Bimedial rectus recession is one of the surgical treatment options for infantile esotropia. It is mainly performed with the Hang-Back technique, which has undesirable side effects. In this study, this technique has been modified, and its results are discussed.METHODS:The files of 120 patients followed with the diagnosis of infantile esotropia and treated bimedial rectus muscle recession using the modified Hang-Back technique were reviewed retrospectively. Cases were evaluated by the time of surgery, coexistence with inferior oblique muscle weakening surgery, and presence of refractive error. The factors investigated on the results of surgical treatment were determined as age, gender, amount of hyperopic refractive error, application age, amount of horizontal deviation, amount of recession, stereopsis, fusion, age of surgery.RESULTS:When the cases were divided into subgroups which were the time of surgery, the operation performed with inferior oblique weakening surgery and presence of refractive error; the difference between preoperative and postoperative 1st month, 6th month, and 1st-year angle of deviation was statistically significant in all three groups (p < 0.001).CONCLUSION:This novel technique aims to prevent unwanted movement of the muscle in the horizontal and vertical axis and a gap in the middle of the recessed muscle, seen in the classical Hang-Back technique. The difference between the preoperative and postoperative angle of deviation was statistically significant. Also, over and under-correction and the development of alphabetic pattern deviation were less common in our modified technique.
Freedom of information. What were they thinking?
Authors: Treadwell Greg 
Published: September 2021

“The right to know is the right to live.”Aruna Roy (1946— ), Indian social activist
Ongoing dissatisfaction among information requesters, including journalists, has discredited the early and partially heroic narratives of the Aotearoa New Zealand freedom-of-information (FOI) regime. The revolutionary and celebrated Official Information Act 1982 (OIA 1982) has remained virtually unchanged since its inception, despite ongoing calls for reform. This article examines why the OIA 1982 was so transformative, calling on the literature and two thematic analyses of historic parliamentary debates as it explores the thinking of the time and historicises the moment lawmakers cemented in statute notions of an open society. All media rely on this law, and the idea of FOI behind it, to be able to flourish, even if some are more acutely aware of that than others. All media practitioners, from journalists to filmmakers, benefit from the informed social discourse that results from FOI. To explore its failings in Aotearoa New Zealand today and, indeed, to start to imagine remedies, this research argues an important first step is to better understand the thinking of the time.
Influence of microelements and attractants on the elements of yield structure and yield of white clover (Trifolium repens L.) seeds
Authors: ĆWINTAL MAREK , GOLIASZ SYLWESTER 
Published: September 2021

A field experiment with the cultivation of white clover for seeds (Barda cv.) was carried out in 2009–2012, in the Experimental Farm in Parczew (22°53'60"E, 51°37'59"N), on typical brown soil (bonitation class IVb), by the split-plot method, in four replicates. The studies included: foliar fertilization with microelements (B + Mo) and attractant – Pollinus. The number of heads per 1 m2, number of pods and seeds in the head as well as the seed yield were determined. Weather conditions had the decisive influence on the yield of seeds and main elements of its structure. The highest seed yield (305.4 kg·ha–1) was obtained in 2010 characterized by more favorable thermal conditions and rainfall in the generative clover sub-period, slightly lower in 2012 (287.7 kg·ha–1), and the lowest in 2011 (49.3 kg·ha–1). Fertilization with microelements (B + Mo) significantly increased the number of heads per 1 m2, the number of seeds in the head and the seed yield. The attractant used at the beginning and full flowering of clover significantly increased the yield of seeds by 35.2 and 78.0 kg·ha–1, respectively. The highest yield of white clover seeds (482.6 kg·ha–1) was obtained due to foliar fertilization with boron and molybdenum and using the attractant – Pollinus to fully flowering plants.
Improvement of Pilot Symbol Orthogonal Sequences in 2×2 to 4×4 MIMO Wireless Communication Systems with Channel State Estimation
Authors: Romanuke Vadim 
Published: September 2021

AbstractMIMO wireless communication systems with channel state estimation, in which 2 to 4 transmit-receive antenna pairs are employed, are simulated. The channel estimation is fulfilled by the orthogonal pilot signal approach, where the Walsh Hadamard-ordered sequences are commonly used for piloting. The signal is modulated by applying the quaternary phase shift keying method. Maximum 250 000 packets are transmitted through flat-fading Rayleigh channels, to which white Gaussian noise is added. Based on simulating 10 subcases of the frame length and number of pilot symbols per frame, it is ascertained that pilot symbol orthogonal sequences in 2×2 to 4×4 MIMO systems can be improved by substituting Walsh functions with partially unsymmetrical binary functions constituting the eight known orthogonal bases. The benefit is that the bit-error rate is substantially decreased, especially for 2×2 MIMO systems. Considering three cases of the pilot signal de-orthogonalization caused by two indefinite and definite pilot sequence symbol errors, the relative decrement varies from 0.123 % to 14.7 %. However, the decrement becomes less significant as the number of transmit-receive antenna pairs is increased.

Published: September 2021

AbstractFlight safety is an integral part of air transportation. Flight accidents are highly unlikely to appear but most of them are caused by the human factor. The aircrew training system for abnormal operations relies on integrated aircraft simulator-based exercises. Crew needs to be trained not to degrade piloting technique quality when facing increased psychophysiological tension. Therefore, methods evaluating the characteristics of ergatic aircraft control systems, warning systems for deterioration due to failures in avionics systems, piloting technique quality, and abnormal operation algorithms are necessary. An analysis of the bank angle has revealed that there are hidden increased tension manifestations in the human operator expressed in the transition of the flight parameter variation from a stationary random process to deterministic fluctuations in the form of a sinusoid. The goal of the research is to increase the efficiency of pilots’ training using integrated aircraft simulators based on the design and implementation of statistical data processing algorithms. To achieve the goal of the research, two algorithms for detecting deterministic fluctuations based on the Neyman-Pearson criterion and the optimal Bayesian criterion are developed. The presented algorithms can be used in the integrated simulator software to automate the decision-making process on piloting quality.
Increasing the Piezoactivity of Manufactured Composite Piezoceramic Transformers by Combining the Processes of Soldering and Polarization
Authors: Paerand Yurii , Zakhozhai Oleh 
Published: September 2021

Abstract
The article is devoted to solving the problem of ensuring high piezoactivity of composite piezoceramic transformers, in which the component parts are connected by soldering. The existing connection features have been analysed for the elements of composite piezoceramic transformers and the results have shown that during soldering the piezoceramic elements are exposed to thermal shock leading to depolarization of piezoceramics and deterioration of its piezoelectric properties. Diminution of temperature depolarizing effect is possible using low-temperature solders with a high tin content. However, in this case, the diffusion process of the electrode material of the piezoelectric element into the solder increases and the mechanical connection strength decreases. To eliminate these negative phenomena and solve the problem, a new method has been developed for connecting elements of composite piezoceramic transformers by soldering, where a polarizing voltage is applied to the composite piezoceramic transformer when heating and cooling, which prevents depolarization of the domain structure of piezoceramic elements. At the same time, high temperature ensures that polarization is carried out at lower values of the electric tension, and a more mobile domain structure after polarization has a lower level of coercive forces and, accordingly, a greater stability of parameters ov er time. Experimental verification has shown that the relative resonance gap increases by 6 % with a decrease in the dispersion of this value by 12 %, which indicates an increase in piezoactivity and stability of the characteristics of composite piezoceramic transformers manufactured using the solution above.
Loneliness and Cyberloafing in the Time of COVID-19: A Psychological Perspective
Authors: Çolak Murat , Çetin Cemile 
Published: September 2021

Abstract

Background
The COVID-19 pandemic, which has affected the entire world, has driven countries into economic, social, and political uncertainty and has forced quite significant changes, especially in areas such as health, work, education, and social security. Social changes that are occurring as a result of the crisis include the restructuring of businesses and working styles and the shaping of work life along the new-normal axis. Many psychosocial risks such as conflict management, organisational relationships, communications problems, job satisfaction, stress, productivity, and performance are being redefined as the nature of jobs, job descriptions, employee competence, and ways of working are being recreated for a virtual environment. The importance of concepts related to work psychology such as loneliness, cyberloafing, digital mobbing, emotional resilience, psychological resilience, compassion, self-compassion, conscious awareness, design of habits, coping with loneliness, and coping with crisis is becoming apparent.

Research aims
The aim of this study is to examine cyberloafing and loneliness with its changing structure in terms of work psychology. In addition, the researchers and their results on cyberloafing and loneliness are discussed in terms of both sociodemographic factors and some variables of work life.

Methodology
The research method of critical analysis of literature on the subject of cyberloafing and loneliness was applied in this study. Common findings of secondary research were used in terms of work psychology.

Findings
The concepts of loneliness and cyberloafing, which have been evaluated in relation to different sociodemographic and work-life factors and whose mutual relations have been the subject of a very limited number of studies, are examined more intensively in the context of personal and organisational factors applicable to the technology-intensive future.

INVERSIVE SEMIOTIC ANALYSIS OF ROMAN OF F. SOLOGUB «LITTLE DEMON»
Authors: Лебедев Владимир Юрьевич , Прилуцкий Александр Михайлович 
Published: September 2021

Данная статья является апробацией авторской методики инверсивного семиотического анализа и исследованием с помощью данной методики конкретного художественного текста - романа Ф. Сологуба «Мелкий бес». В основе инверсивного семиотического анализа лежит представление об инверсии - особом типе отношений в иерархических структурах, при которых низший элемент обретает главенствующие свойства, формально оставаясь на прежней, подчиненной позиции. Проведенные исследования позволили выявить в тексте романа различные уровни инверсии: в поведении и описании героев, изображении социальных и психических процессов. Это позволило сделать вывод о том, что инвертивность семиотических планов формирует семиотический код текста.
This article is an approbation of the author's method of inverse semiotic analysis and research with the help of this method of a specific literary text - the novel by F. Sologub «The Little Demon». Inverse semiotic analysis is based on the concept of inversion - a special type of relationship in hierarchical structures in which the lower element acquires dominant properties, formally remaining in the same subordinate position. The studies carried out allowed us to identify different levels of inversion in the text of the novel: in the behavior and description of the characters, in the depiction of social and mental processes. This made it possible to conclude that the inversion of semiotic plans forms the semiotic code of the text.

Authors: KOKULU Kamil , SERT Ekrem Taha , MUTLU Hüseyin 
Published: September 2021

Aim: Bedside ultrasonography (US) is a frequently used tool to facilitate diagnosis and treatment in emergency departments (EDs). The primary aim of our study was to evaluate the characteristics of emergency physicians’ use of bedside US. Our secondary aim was to analyze factors affecting the regular use of bedside US.
Material and Methods: This was a descriptive cross-sectional survey study conducted with physicians working in EDs. The study was carried out using a 15-item questionnaire in 2020, and the results were analyzed with the Statistical Package for the Social Sciences software.
Results: The questionnaire was sent to 965 physicians working in the EDs of 48 different hospitals, and the data of 684 (71.5%) that responded to all items in the questionnaire were included in the study. The EDs of the hospitals included in the study had at least one US device, and 82% of them were equipped with three probes. It was observed that 152 (22.2%) of the emergency physicians did not use US at all, and 532 (77.8%) used US regularly, albeit rarely. The most common area of use for US in the ED was focused assessment with sonography in trauma, followed by procedural guidance (432 [63.2%] and 308 [45%], respectively]. Of the physicians who did not use bedside US regularly, 33.3% (n=96) stated that they did not use it due to their lack of training. In addition, the interest of emergency physicians in US education was measured as 7±3 points. It was observed that the conditions associated with frequent use of bedside US were gender, inclusion of US training during residency, and duration of the availability of an US machine in the emergency clinic.
Conclusion: This study showed that emergency physicians had a high interest in using bedside US. The greatest obstacle to the use of US was insufficient training. Therefore, emergency physicians should be offered regular US training programs sand those that have not received US training should be encouraged to participate in such programs.

Published: September 2021

Amaç: Bu çalışmada, amatör olarak spor yapan ve ön çapraz bağ (ÖÇB) rekonstruksiyonu yapılan bireylerde, operasyonun fonksiyonel sonuçları ve sportif aktiviteleriyle olan ilişkisinin araştırılması amaçlandı.
Gereç ve Yöntem: Ön çapraz rüptürü nedeniyle dört katlı hamstring otogrefti ile artroskopik rekonstrüksiyon uygulanan hastaların fonksiyonel sonuçlarını Lysolm ve Tegner aktivite skorlama sistemi ile retrospektif olarak anali ettik. Kinezyofobi değerlendirilmesi Tampa ölçeği kullanarak yapıldı.
Bulgular: Çalışmaya dahil olan 61 kişinin tamamı erkekti (yaş dağılım: 17 - 48 yıl, ortalama: 30.6±6.9). Takip süresi en kısa 27 ay iken en uzunu 74 ay olmak üzere ortalama 47,4 ay idi. Ameliyat öncesi ortalama 59,1 (dağılın: 5 - 90) olan Lysholm skoru son kontrolde 95,9’du (dağılın: 69 - 100). Tegner aktivite skorları ortalaması travma öncesi 6,4 (dağılın: 3 - 10), ameliyat sonrası 5,2 (dağılın: 3-10) idi. Tampa kinezyofobi ölçeği 41.2 (29-49) bulundu.
Sonuç: Cerrahi sonucunda, hastaların çoğunda fonksiyonel sonuçlar tatmin edici olarak tespit edilirken, yaklaşık yarısında ise aktivite skorları istenilen düzeye ulaşmıştı. Tampa kinezyofobi ölçeği yüksek bulunması, ÖÇB cerrahisinde ne kadar titiz davranılsa da ameliyat önce ve sonrasında alacağı profesyonel fizyoterapi ve psikolojik danışmanlığın da önemli derecede etkili olabileceğini gösterdi.
