Published: May 2024

Studi purpose. The purpose of this study was to determine the ideal coach skills for Table Tennis.
Materials and methods. This research was descriptive and quantitative using a survey. The sample of this study were athletes who had won medals in table tennis competitions at the city or district level in Riau Province and Yogyakarta Special Region (DIY) Province as evidenced by certificates during 2023. Therefore, the sample of table tennis athletes involved was 70 athletes (44 boys and 26 girls). The characteristics of the athletes were an average age of 18.7±7.2 years and 6.1±0.9 years of training experience. The research instrument was a questionnaire distributed via a Google form. The questionnaire contained 20 statement items with a scale of 1 - 4. The coach's skills are divided into 4 factors (table 1), which were 1) skills in applying sports techniques, 2) skills in applying training periodization, 3) psychological skills, and 4) communication skills.
Results. Table Tennis Coaches' skills in general showed "very poor" 2 answers (3.32%), "poor" 19 answers (28.33%), "fair" 25 answers (33.53%), "good" 22 answers (31.68%), and "very good" 2 answers (3.32%).
Conclusions. From the results of this study, it is expected that the Riau Province and DIY Province table tennis organizations pay more attention to the quality of coach skills. One effective solution at this time is to provide training to coaches in stages. Further, providing opportunities for former athletes who no longer have a career to be given basic coaching knowledge so that later they can become professional coaches.

The high prevalence of cardiovascular diseases (CVD) requires the development of new methods for their timely preliminary diagnosis. One of the promising approaches in this direction is the analysis of photoplethysmogram (PPG). The article presents an algorithmic method of digital processing of the PPG signal for automatic determination of the position of characteristic points on the pulse wave. This task is relevant, as amplitude and time characteristics of the location of characteristic points allow obtaining information about the state of the cardiovascular system (CVS). The developed method is characterised by low sensitivity to the variability of the signal shape due to the application of differentiation and interpolation procedures. The proposed solution can be used for creation of modern technical means of preliminary diagnostics of CVS.

In this paper, we study the analysis of the contact of bevel gear teeth based on machine learning methods. Bevel gear teeth are widely used in various industrial and mechanical systems to transmit rotational motion with high precision and reliability. Traditional methods of gear contact analysis are based on mathematical models and empirical formulas, which may be limited in accuracy and applicability. In recent years, machine learning has become a powerful tool in the field of engineering and mechanics to more accurately model and predict the contact behavior of bevel gear teeth. The paper proposes the use of machine learning methods, such as neural networks or deep learning algorithms, to train models capable of analyzing the contact of bevel gear teeth. Wear, load, and gear geometry data can be used to train models, which can then predict contact parameters and evaluate contact performance.

Published: May 2024

This paper presents the results of a study on optimising the feed stream pressure of the Mixed Fluid Cascade natural gas liquefaction cycle. The objective is to optimise the pressure of the feed stream to distribute heat effectively over the cooling stages and reduce the energy cost of the cycle. To achieve the goal, the following tasks have been done: constructing the mathematical model of the cycle, per-forming the calculation experiment for different values of the feed stream pressure to determine energy characteristic values, and determining the optimal values of feed stream pressure. The flow characteristics of the working substances in the cycle are determined based on the Peng–Robinson–Stryjek–Vera equations of state and Benedict–Webb–Rubin. The mass flow of the working substance is calculated for each cycle's stage heat load, at both constant and different values of the working point temperatures. The distribution of heat load for liquefying 1 kg of natural gas by stages is displayed, and achievable working point temperatures of the feed flow are determined. The energy consumed by the compressor units and the amount of compression heat dissipated are calculated. The study's main finding is that the optimal feed pressure in the Mixed Fluid Cascade cycle is higher than the standard pressure. The significance of the obtained results lies in the significant reduction of energy costs of the Mixed Fluid Cascade cycle at a feed stream pressure of 13 MPa.

Authors: Bosneaga Valeriu , Suslov Victor
Published: May 2024

The purpose of the work is study of special asymmetric modes of new three-phase autotransformer device for flexible connection of alternative current power systems. The universal model was developed for the device, containing two autotransformers - the main phase-shifting and the additional regulating autotransformer. The model allows studying both symmetric and almost any asymmetric modes of the considered circuit. It became possible to connect asymmetrically the loads in different phases of the regulating autotransformer, as well as arbitrary connect the regulating autotransformer itself to the hexagon taps. According to the calculated values of currents, voltages and magnetic fluxes of the device the visual vectorial diagrams were constructed for the main and the regulating autotransformer, explaining specific of considered operating modes. It was shown that device’ currents in such modes contain symmetrical components of both zero and negative sequences. Also, at asymmetric connection of the regulating autotransformer, the relative magnetic flux of the legs of the main and regulating autotransformers are asymmetrical, but in main autotransformer their sum is approximately equal to zero and magnetic flux practically does not escape into the surrounding space. Radically different situation is observed in the regulating autotransformer. The significant zero-sequence fluxes arise with the release of significant (about 50%) magnetic flux into the surrounding space. This re-quires special measures to be taken to limit its harmful effects on the operation of the autotransformer.

Contextualizing indigenous venturing: emerging insights for context-based indigenous entrepreneurship research
Authors:   ,   Universidad del Desarrollo, Barros Celume Sebastián
Published: May 2024

We have a limited understanding of entrepreneurship beyond Western developed contexts. Commonly, mainstream entrepreneurship research relies on assumptions which do not always hold across different segments of the population, such as Indigenous peoples , a still marginalized and under researched segment of society . D espite its relevance for emancipation , economic independence, and sustainable development among Indigenous communities worldwide, Indigenous entrepreneurship remains largely understudied in our field . Therefore , in this doctoral thesis composed of two research articles, I examine some underexplored aspects of Indigenous venturing, focusing on the cultural backgrounds and contextual specificities in which Indigenous entrepreneurship takes place . In doing so, I seek to stress the need for more inclusive research, urging a reconsideration of some of our common knowledge and taken for granted entrepreneurial perspectives. In the first article of this dissertation , I explore the interface between Indigenous entrepreneurship and place, considering both the 'material' and 'socially constructed' dimensions of place. Specifically, I examine Latin American Indigenous individuals from different ethnicities, engaging in venturing across urban, remote, and rural locations. My findings put into perspective the key influence of place in Indigenous venturing , ranging from deeply embedded and relational ventures in remote settings to Western influenced business approaches within urban areas . Overall, I contribute with an empirical typology that provides a more detailed understanding of the context laden and highly idiosyncratic nature of Indigenous entrepreneurship , focusing on the emergence, orientation, main outcomes, and constraints among Indigenous ventures from different places and groups of people Building on embeddedness theory, in the second chapter of this dissertation I seek to gain new insights into the embedding process among Indigenous entrepreneurs migrating from their native settlements into urban environments . M y findings reveal that migrant Indigenous entrepreneurs engage in distinct ive prosocial and sustainable ventures, bringing their context laden traditions, beliefs, and values to the urban realm through their businesses . Based on this evidence , I showcas e the pivotal role that their home contexts play in the ir agentic embedding wi thin host contexts . I also contribut e to a multi contextual understanding of embeddedness, considering both distal and proximal contexts at a time.

Assad Regime’s ‘Useful Syria’ Strategy for Survival: Forced Displacement, Refugee, and Demographic Change
Authors:   The Institute of Middle East, Hwang Yuihyun
Published: May 2024

One of the Assad regime’s strategies to survive is control over strategically important ‘useful Syria (suriya al-mufidah)’. For this purpose, the Assad regime forced displacement of local residents, especially Sunnis. Meanwhile, anti-government forces claim that the Assad regime and its allies are turning Sunnis into a minority group in Syria through deliberate demographic change. This study analyzes the goal of the Assad regime’s refugee strategies in ‘Useful Syria’ and examines the suspicions about the Shiaization of Syria. The debate on demographic changes in ‘Useful Syria’ suggests that the perspective distinguishes between ‘us’ and ‘the enemy’ based on sectarian identity continues to be an important factor in the Syrian civil war.
Exploring a Masters of Business Administration’s Impact on Surgical Subspecialists
Authors: McCarter Jacob , Martin Benjamin , Coello Pablo , Brann Christopher
Published: May 2024

Objectives and Study Design

As healthcare evolves, more physicians are taking on administrative roles and pursuing additional graduate education, particularly obtaining a Master’s in Business Administration (MBA.) To facilitate a better understanding of these practitioners, we conducted a comparative study of MD/MBA clinicians in multiple surgical fields.

Methods

This study aims to compare clinicians with MD/MBAs across multiple surgical subspecialties. Reported metrics include demographics, MBA program structure, salary changes, and professional pursuits. Nine studies were obtained from the PubMed, Cochrane, and Embase databases. Four studies met the inclusion criteria and were analyzed.

Results

The majority of MD/MBA degree holders in plastic surgery (95%), orthopedic surgery (89-96%), and ophthalmology (80%) are male. Ophthalmology (37%) demonstrates the highest number of subjects obtaining an MBA via a synchronous MD/MBA. Most clinicians return to clinical practice after degree completion and show high levels of non-clinical pursuits after receiving their MBAs.

Conclusions

Though there appear to be differences across surgical subspecialties regarding how an MBA is applied, most maintain clinical duties. Of those that do not, the largest portion transition to administrative duties, consulting, entrepreneurial endeavors, or other professional opportunities. Despite the financial ambiguity of an MBA, physicians value the transformative experience it offers.

Published: May 2024

Dünya üzerindeki tüm bitkiler gibi asmalar da yetiştirilirken bir çok biyotik ve abiyotik stres unsurlarıyla karşılaşmaktadır. Asmalarda sekonder metabolizma ürünü olarak ortaya çıkan fenolik bileşikler; aslında abiyotik ve biyotik stres faktörlerine karşı hücresel düzeyde kendini savunma mekanizmasıdır. Diğer yandan sekonder metabolit üretimi artışı da kalite için istenen bir durumdur. Bilindiği üzere üzüm tanesinin fenolik bileşen içeriği oransal olarak sıralandığında bunun yarısından fazlası çekirdekten gelmektedir; üzüm çekirdeği de önemli bir biyoaktif bileşendir. Bu araştırmada yedi farklı abiyotik ve biyotik stres uygulamasına (Kontrol, Botrytis cinerea, darbe, yaprak alma, yaprak yaralama, UV-C, vibrasyon) tabi tutulan Cabernet Sauvignon ve Merlot üzüm çeşidi omcalarından hasat edilen salkımların içindeki çekirdekler incelenmiştir. Çekirdeklerde; tanedeki çekirdek sayısı, çekirdek yaş ve kuru ağırlığı, tane yaş ağırlığı-çekirdek yaş ağırlığı, tane kuru ağırlığı-çekirdek kuru ağırlığı, çekirdek oranı (yaş-kuru), çekirdek su oranı, 1 çekirdek yaş ağırlığı ve 1 çekirdek kuru ağırlığı ölçümleri yapılmıştır. İncelenen kriterlerde, çeşit kaynaklı bazı farklılıkların görüldüğü ancak uygulamalar dikkate alındığında belirgin bir farklılık olmadığı anlaşılmıştır. Buradan hareketle omcalar için bazıları omcaya kalıcı hasar verebilecek olan UV-C, darbe, vibrasyon ve tüm yaprakları alma gibi abiyotik streslerin sonraki yılın (2017) göz uyanması, salkım doğuşu, salkım verimi, çekirdek yapısı gibi özelliklere olumusz bir etkisi olmadığını görmek bakımndan önemli sonuçlar elde edilmiştir. Sekonder metabolit üretimini artırmak amacıyla gerçekleştirilen abiyotik ve biyotik streslerin çekirdek özelliklerini negatif etkilemediği belirlendiğinden, gerektiğinde bu uygulamaların yapılabileceği sonucuna varılmıştır.

Son yıllarda LED ışık uygulamalarının, bitki büyüme ve gelişiminin kontrol altına alınması ve farklı çevresel stres koşullarına karşı toleransın artırılması bakımından etkili bir strateji olduğu bildirilmektedir. Bu çalışmada kuraklık stresi altındaki asma anaçlarının morfolojik, fizyolojik ve biyokimyasal özellikleri üzerine kırmızı, mavi, yeşil ve gün ışığı (kontrol) olmak üzere farklı dalga boylarına sahip ek LED ışık uygulamalarının etkileri incelenmiştir. Deneme, 2023 yılında Yozgat Bozok Üniversitesi Ziraat Fakültesinde mevcut tam otomasyonlu iklim odası ve araştırma laboratuvarlarında yürütülmüştür. Bu amaçla, kuraklığa toleranslı “1103 P” ve hassas “5 BB” Amerikan asma anaçlarına ait bir yıllık çelikler kullanılmıştır. Dikim işleminden yaklaşık 6 hafta sonra kuraklık stresi uygulanan fidanlarda yetiştirme ortamlarının nemi, tarla kapasitesinin %30-40’ı aralığında tutularak kısıtlı sulama yapılmış; kontrol gruplarda ise tarla kapasitesinin %70-80’i aralığında normal sulama yapılmıştır. Toplam 60 günlük yetiştirme periyodunun ardından deneme sonlandırılarak, asma fidanlarına ait morfolojik, fizyolojik ve biyokimyasal parametreler analiz edilmiştir. Elde edilen bulgular, asma fidanlarında kalite parametrelerinin iyileştirilerek kuraklık stres zararının azaltılması bakımından en etkili uygulamaların kırmızı ve mavi ek LED ışık uygulamaları olduğunu göstermiştir. Bu çalışmanın, örtüaltında yetiştirilen tüplü asma fidanlarının kalitesinin yükseltilebilmesi ve sulama suyunun daha etkin kullanımının sağlanması amacıyla gerçekleştirilecek çalışmaları kolaylaştıracağı ve kuraklık stresine toleransın artırılmasına yönelik yürütülecek araştırmalara önemli bir referans sağlayacağı düşünülmektedir.
MAS Yöntemiyle Domates Lekeli Solgunluk Virüsü’ne Dayanıklı Domates Hatlarının Geliştirilmesi

Published: May 2024

Domates, Solanaceae familyasına ait dünyada ve ülkemizde yetiştiriciliği en fazla yapılan sebze türüdür. Domates yetiştiriciliğini olumsuz yönde etkileyen birçok hastalık etmeni ve zararlı bulunmaktadır. Domates lekeli solgunluk virüsü (Tomato spotted wilt virüs, TSWV), bazı ülkelerde karantina kapsamında bulunan, Thrips tabaci ve batı çiçek tripsi (Frankliniella occidentalis) tarafından taşınan tehlikeli bitki virüslerinden biridir. Bu amaçla, Ege Tarımsal Araştırma Enstitüsü domates gen havuzunda yer alan sofralık ve sanayilik tüketime uygun domates hattı hassas M68 ile Tomato Genetic Resource Center (TGRC)’den temin edilen Domates lekeli solgunluk virüsüne dayanıklı LA3667 ile melezleme yapılarak oluşturulan popülasyonda MAS yöntemi kullanılarak homozigot dayanıklı nitelikli hatların moleküler olarak seleksiyonu yapılmıştır. Bu amaçla F₂ ıslah kademesinde monogenik (1:2:1) açılımına göre 150 F₂ bireyinde 35 homozigot dayanıklı, 74 heterozigot dayanıklı ve 41 hassas birey elde edilmiştir. Dayanıklı olarak belirlenen homozigot dayanıklı hatlar, F₄ kademesine kadar kendilenmiş, F₄ kademesinde tekrar moleküler olarak testlenmiş, Sw-5 lokusu bakımından homozigot dayanıklı 3 hat ve 2 hassas domates ıslah hattı mekanik inokülasyon yoluyla biyolojik testlemeye alınmış ve dayanıklılık sonuçlarının, moleküler ve biyolojik olarak birbiriyle uyumlu olduğu görülmüştür.

Farklı ekolojik alanlar için uygun üzüm çeşitlerin seçilmesi çok uzun zaman almaktadır. Değişen çevre şartları bağ lokasyonları için geleneksel çeşitlerin önemini artırmaktadır. Bu nedenle lokal çeşitlerin öncelikle tanımlanması, korunması ve benzer ekolojiler için tanıtılması gerekmektedir. Üzüm çeşitlerinin tanımlanması (The International Organisation of Vine and Wine, Uluslararası Bağ ve Şarap Örgütü) (OIV) tarafından geliştirilmiş olan tanımlayıcılar global ölçekte kabul edilmektedir. Tanımlanan çeşitlerin genetik erozyona uğramalarının önlenmesi için muhafaza edilmeleri bu çeşitlerin kazanımlarının gelecekte de kullanılmasını mümkün kılabilecektir. Bu çalışmada Muğla ili Seydikemer ilçesinde deniz seviyesinden 200-800 m aralıkta üretici bağlarında yaklaşık 2000 da alanda yetiştiriciliği yapılmakta olan Margaz üzüm (Vitis vinifera L.) çeşidinin ampelografik özellikleri tanımlanmıştır. 2012 yılında son şekli verilen ülkemizin de üyesi bulunduğu OIV üzüm ve asma anaç çeşitleri tanımlama kriterleri listesinde yer alan 69 asıl tanımlayıcı karakterden 63’ü ve 89 tamamlayıcı karakterden 81’i olmak üzere toplam 144 özellik kullanılmıştır. Margaz çeşidi Vitis vinifera özellikleri taşımaktadır. Sürgün ucu açık, genç yaprakları yatık tüylü, antosiyanin renklenmesi sürgün ucu, genç yaprakları ve sürgünde incelenen özellikler için belirgindir. Olgun yaprakları koyu yeşil 5 belirgin loblu, beşgen şekillidir. Çok verimli omcalardaki ortalama salkım ağırlığı 375 g, tane ağırlığı 2.44 g, tane saptan kopma direnci 3.7 N ve tane yırtılma direnci 3.62 N olup 15 Ağustos 2023 tarihinde 800 m yükseklikteki bir bağda 16.5°Brikse ve 15 Eylülde 22°Brikse erişmiştir. Çeşidin sıcak ekolojiye uyum sağlamış olması, Ağustos’ta yeme olumuna ulaşmış olmasına rağmen omca üzerinde yıl sonuna kadar kalabilmesi gelecek için potansiyel oluşturmaktadır.

Türkiye kuşkonmaz genetik kaynakları yönünden zengin bir ülkedir. Sebze ve tıbbi amaçlı kullanılabilen kuşkonmazın ticari olarak üretim ve pazarlaması gelişmemiştir. Fakat kırsal kesimde yaşayanlar Türkiye’nin farklı bölgelerinde farklı türleri toplayıp severek tüketmekte ve yerel pazarlarda satışını yapmaktadır. Halk tarafından “Tilkişen”, “Mercü” gibi yöresel isimler verilmektedir. Türkiye’de varlığı teyit edilmiş 10 tür doğal olarak varlığını sürdürmektedir. Bunlar; Asparagus officinalis L. (Bahçe Kuşkonmazı), Asparagus acutifolius L., Asparagus aphyllus L., Asparagus verticillatus L., Asparagus lycicus P.H. Davis (Endemik), Asparagus coodei P.H. Davis (Endemik), Asparagus lycaonicus P.H. Davis (Endemik), Asparagus persicus Baker, Asparagus palaestinus Baker, Asparagus tenuifolius Lam. türleridir. Asparagus trichophyllus Bunge ve Asparagus filifolius Bertol isimli iki türün ise varlığının teyidinin gerekliliği belirtilmiştir. Yalova Atatürk Bahçe Kültürleri Merkez Araştırma Enstitüsünde yürütülen “Türkiye Kuşkonmaz (Asparagus spp.) Genotiplerinin Toplanması, Muhafazası ve Karakterizasyonu” isimli proje kapsamında türlerin toplanması ve karakterizasyonu devam etmektedir. Toplamda 141 lokasyondan 10 türe ait örnekler toplanmıştır. Bu çalışmada bu türlerin dağılım alanları ile yöresel adları ve sebze olarak kullanımları bildirilecektir.
