sEmg tabanlı el hareket tanımada farklı kol pozisyon ve açılarının sınıflandırma başarısına olan etkilerinin incelenmesi
Authors: Parlak Emre , Başpınar Ulvi
Published: May 2024

EMG tabanlı uygulamalar ile ilgili literatürde oldukça çok sayıda çalışma yer almaktadır. Bu çalışmalar, insan makine etkileşimi başta olmak üzere rehabilitasyon, aktif protez kontrolü gibi alanlarda yoğunlaşmıştır. Yapılan çalışmalarda EMG sinyallerinin sınıflandırılmasında sınıflayıcıların performansını etkileyen kol kaslarının yorulması, ciltteki ter, elektrotlardan kaynaklanan gürültüler gibi çok sayıda faktörden bahsedilmiştir. Yapılan bu çalışmaların birçoğunda EMG kayıtları ön kol sabit ve belirli bir pozisyondayken yapılmıştır. Hareketin yapıldığı kol pozisyonu ve bilek açıları da hareket tahminini etkileyen etkenlerdendir. Aktif protez kontrolü, insan makine etkileşimi gibi sistemlerde kullanılan sEMG sinyallerinin günlük hayatın akışında kolun farklı pozisyon ve açılarında da doğru sınıflandırması beklenmektedir. Bu çalışmada birden fazla kişinin sağ ön kollarından alınan yüzey elektromiyogram sinyalleri kullanılarak el hareketleri, bu el hareketlerinin yapıldığı bilek açıları ve kol pozisyonları tespit edilmek istenmiş, aynı zamanda farklı kol pozisyonlarının ve açılarının el hareket sınıflamasındaki etkileri araştırılmıştır. Hareketin yapıldığı farklı kol pozisyonları ve açılar nedeniyle ortaya çıkan olumsuz etkilerin ivme ve jiroskop verileri kullanılarak giderilip giderilemeyeceği noktasında da değerlendirmeler yapılarak sınıflandırıcı performanslarına etkilerine yer verilmiştir. Sınıflandırma aracı olarak yapay sinir ağları ve destek vektör makineleri kullanılmış, performans karşılaştırması yapılmıştır. Yapılan değerlendirme sonucu günlük hayatta kullanılması planlanan EMG tabanlı bir sistemin eğitiminde ön kolun tüm pozisyon ve açılarında eğitim verisinin toplanması sınıflandırma sonuçlarını iyileştirdiği tespit edilmiştir. Farklı pozisyonlarda ivme ve jiroskop verilerinin hareket sınıflama performansına çok az bir katkı sunduğu belirlenmiştir. Çalışma kapsamında yalnız EMG verisinin bilek açısını ve kol pozisyonunu tespit etmekte yetersiz olduğu ivme ile jiroskop verilerinin eklenmesi ise bilek açısı tahminleri yükseltmiştir. Kol pozisyonu tespitinde ise EMG ile birlikte ivme verisinin kol pozisyon açısını belirlemede etkin olduğu görülmüştür. Sınıflandırıcı performansı olarak gruplar incelendiğinde genel olarak DVM sınıflayıcısının daha yüksek sınıflama performansı göstermekle beraber YSA’nın da iyi sonuçlar verdiği gözlenmiştir.

Published: May 2024

Ülkemizde ve dünyada teknolojinin gelişmesi ile enerji ihtiyacı her geçen gün artmaktadır. Bu sebeple, ısı enerjisinin verimli kullanılması çok önemlidir. Az miktarlarda nanomalzeme kullanılarak oluşturulan nanoakışkan sistemler üstün termofiziksel özellikleri nedeni ile ısı transferini ve enerji verimliliğini artırmaktadırlar. Bu sebeple nanoakışkanların üretilmesi ve termofiziksel özelliklerinin incelenmesi önem arz etmektedir.

Bu çalışmada, yüksek sıcaklıkta oksidasyon yöntemi ile Polietilen glikol (PEG) ve Alginat katkı maddeleri varlığında titanium dioksit (TiO2) nanopartiküllerinin sentezlenmesi ve sentezlenen nano titanyum dioksitlerden farklı konsantrasyonlarda su bazlı nanoakışkan elde edilmesi amaçlanmıştır. Ayrıca, yüzey aktif madde türünün ve konsantrasyonunun nanoakışkanın stabilizasyonuna etkisini incelemek amacı ile farklı konsantrasyonlarda sodyum dodesil sülfat (SDS) ve arap zamkı kullanılmıştır. Sentezlenen TiO2 partiküllerinin karakterizasyonu için XRD, SEM, FTIR ve BET ölçümlerinden yararlanılmıştır. Nanoakışkanların önemli termofiziksel özelliklerinden stabilizasyonu ve yoğunluğu da bu çalışma kapsamında ölçülmüştür. Gerçekleştirilen deneysel çalışmalar sonucunda, Alginat katkı maddesi ile üretilen TiO2 nanopartiküllerinin, nanoakışkanın stabilizasyonunda PEG katkı maddesi ile üretilene göre daha başarılı olduğu görülmüştür.

Authors: Uçakkuş Ömer Emre
Published: May 2024

Üretim teknolojilerinin gelişimine paralel olarak sürdürülebilirlik kapsamında sınırlı enerji kaynakları dikkate alındığında, düşük enerji sarfiyatı ile üretilebilen, hammadde ve fire miktarı en düşük olan, karmaşık geometrili ve yüksek mukavemetli parçalara olan talep artmaktadır. Bu tip parçaların üretilebileceği proseslerden en önemlilerinden birisi de sac şekillendirme yöntemidir. Dar toleranslara sahip yüksek mukavemetli parçaların üretiminde gerek parçanın gerekse kalıbın aşırı yüklemelere maruz kaldığı derin çekme prosesi yoğunlukla kullanılmaktadır. Aşırı yüklenmelerden dolayı, derin çekme kalıplarında meydana gelen sürtünme ve aşınmalara karşı tribolojik performansının yüksek olması beklenmektedir. Kalıp yüzeylerine doku oluşturma işlemi ise son zamanlarda dikkatleri üzerine çeken ve tribolojik performansı arttıran yöntemlerden biridir. Bu çalışmada endüstriyel bilyalı dövme prosesleri kullanılarak kalıp üzerinde yüzey dokusu oluşturulmuştur. Kaplamasız ve CrN kaplanmış dokulu yüzeyler üzerinde yapılan kuru ve sıvı sürtünme test sonuçları düz yüzey test sonuçları ile kıyaslanmıştır. Kinetik sürtünme katsayısı kuru ve sıvı sürtünme durumunda sırasıyla 0,21’den 0,16’ya (%25) ve 0,15’ten 0,06’ya (%60) düşmüştür. CrN kaplanmış triboloji testlerinde ise kuru sürtünme durumunda düşüş olmazken sıvı sürtünme durumunda ise kinetik sürtünme katsayısı 0,09’dan 0,05’e (%41) düşmüştür.

KAT8 compound inhibition inhibits the initial steps of PINK1-dependant mitophagy v2
Authors: de Talhouet Capucine , O'Callaghan Benjamin , Plun-Favreau Helene , Esteras Noemi
Published: May 2024

It has recently been shown that KAT8, a genome-wide association study candidate risk gene for Parkinson’s Disease, is involved in PINK1/Parkin-dependant mitophagy. The KAT8 gene encodes a lysine acetyltransferase and represents the catalytically active subunit of the non-specific lethal epigenetic remodelling complex. In the current study, we show that contrary to KAT5 inhibition, dual inhibition of KAT5 and KAT8 via the MG149 compound inhibits the initial steps of the PINK1-dependant mitophagy process. More specifically, our study shows that following mitochondrial depolarisation induced by mitochondrial toxins, MG149 treatment inhibits PINK1-dependant mitophagy initiation by impairing PINK1 activation, and subsequent phosphorylation of Parkin and ubiquitin. While this inhibitory effect of MG149 on PINK1-activation is potent, MG149 treatment in the absence of mitochondrial toxins is sufficient to depolarise the mitochondrial membrane, recruit PINK1 and promote partial downstream recruitment of the autophagy receptor p62, leading to an increase in mitochondrial delivery to the lysosomes. Altogether, our study provides additional support for KAT8 as a regulator of mitophagy and autophagy processes.

Virtual Learning Environment in a Philippine Higher Education Institution: Acceptance and Practices
Authors:   College of Teacher Education, Cebu Normal University, Philippines, Petancio Jo Ann M.
Published: May 2024

Acceptance and practices in the use of virtual learning environments in Philippine higher education institutions should be explored to provide insights for its long-term implementation and to sustain quality education. This study extends the technology acceptance model to include perceived pedagogical impact and personal innovativeness, and examines the prevalent practices in the utilization of the virtual learning environment in a higher education institution in Cebu City, Philippines, in accordance with the principles for Universal Design for Learning. Participants in the study included 567 students who completed an online survey questionnaire. This quantitative study utilized structural equation modeling that revealed how perceived pedagogical impact and personal innovativeness have a significant impact on perceived usefulness and perceived ease of use, respectively. Also, perceived usefulness and perceived ease of use are both related to behavioral intention to use, which influences the actual use of the virtual learning environment. The results demonstrated how various practices and strategies were perceived by the students as being frequently used in the virtual learning environment by using the average of the weighted means. The list was topped by student-teacher interactions and student-platform interactions, with timely feedback coming in last. The findings suggest that higher education institutions may assess students’ innovativeness and perceptions of the impact of virtual learning environments right from the start. Enhancement programs may subsequently be implemented. Furthermore, faculty members may be trained in the use of digital tools to hone the time management skills of students and implement cooperative learning activities and effective feedback mechanisms in the online mode.

Análisis de las conductas anticompetitivas en la era digital: relaciones B2B y B2C
Authors: Cárdenas Vera Kelly Johana
Published: May 2024

El Estado colombiano como ente regulador de los cambios en el mercado no puede ignorar la realidad a la que se enfrenta la economía con la inclusión de las plataformas digitales, por ello, este artículo analiza la importancia del cambio en las dinámicas comerciales como consecuencia de la innovación en el derecho de consumo. Así mismo, examina cómo esta nueva era dinamiza las relaciones entre empresas y consumidores –B2B y B2C– generando novedosos escenarios de competencia que van de la mano de nuevas conductas anticompetitivas. En primer lugar, se hará un análisis de la política antitrust digital actual, desarrollada en gran parte en escenarios de la Unión Europea y Estados Unidos, los cuales serán tomados como referentes para posteriormente contrastar sus perspectivas contra las manejadas actualmente en el derecho de competencia colombiano.
A continuación, se contextualizarán las conductas anticompetitivas reguladas por la legislación nacional y se proyectará dicho estudio en comparación con las situaciones extranjeras, revisando las similitudes que eventualmente podrían permear los mercados colombianos. Finalmente, se concluirá que las relaciones –B2B y B2C–, las cuales ahora responden mayormente a la recolección y uso de datos, están siendo transformadas a través de entornos comerciales acelerados. Estos, pretenden ser encajados en normativas estáticas a pesar de encontrarse en mercados dinámicos, situación que debe ser analizada por el Estado colombiano para diferenciar las conductas en favor de la competencia de las anticompetitivas en beneficio de las empresas y los consumidores.
Country-Level Sustainability Indicators in Central and Eastern Europe: Integrating Un Sdgs and Ecological Footprint to Identify Meaningful Clusters and Assess Regional Performance
Authors: Radácsi László , Szigeti Cecília
Published: May 2024

The development of sustainability indicators at the national level emerged due to the limitations of using GDP as a measure of well-being, sustainability, and resilience. Over time, various indicators have been formulated, with a shift in focus from solely economic growth to a more encompassing perspective. The objective of this study was to integrate two methodologies, namely UN Sustainable Development Goals Index (SDGI), and the Global Footprint Network’s Ecological Footprint (EF), in order to identify meaningful clusters of countries based on both measures. Our secondary aim was to reveal the similarities and differences between countries of the Central and Eastern European region. The clustering outcomes revealed that a three-cluster solution can be considered satisfactory. The results confirm the absence of decoupling at a macro level and provide evidence that the SDGs adequately address the intricate nature of sustainability. As for the countries in Central and Eastern Europe we found that this country group's SDGs is above average, but this group of countries is not homogeneous. Significant disparities are apparent in the variations observed in the SDG 9 scores.
The Emergence and Relevance of Different CSR Motivational Factors Among Hungarian SMEs
Authors: Győri Zsuzsanna , Reicher Regina Zsuzsánna , Kolnhofer-Derecskei Anita
Published: May 2024

The paper aims to observe Corporate Social Responsibility (CSR) related motivations in the Hungarian small- and medium-sized enterprise (SME) sector. Literature on CSR distinguishes SMEs from large companies. Being closer to stakeholders, they have special motivational patterns and different possibilities. These features result in special mindset, vocabulary, and activities related to CSR. Based on the literature, we differentiate three types of motivational factors: the Friedmannian view, business case, and moral case. Within all three types, we separately handle incentives and disincentives of CSR. In our comprehensive research on sustainability implications (e.g., stakeholders, motivations, supporting and hindering factors, topics, and activities) among Hungarian SMEs, we used mixed methodology. In the exploratory phase, the qualitative method covered three focus group sessions. Based on the qualitative results, we designed a structured and systematic questionnaire that was surveyed on a representative sample of 300 SME leaders in 2023. Within the 3 types, a total of 9 motivational statements have been selected for the current study to highlight the most dominant motivational characteristics among Hungarian SMEs. Although the business case exists, the moral responsibility of SME leaders is highlighted, and it is tangible that we have gone beyond Friedman’s idea about the priority of profitmaking.

Published: May 2024

Young students start new phase of their lives at university after finishing secondary school. Like any transition in life, the period after leaving high school can be a shock and a crisis. The many changes, the many places to fit in and the start of independent life all coincide, and this can cause considerable anxiety for young people, as most of them are starting their independent lives at this time. These students will be workers in the future carrying these effects with them. The aim of this study is to understand the mental health status and problems of first-year students currently enrolled for three undergraduate business courses in Budapest, in Hungary. This research used the EPOCH model and the validated EPOCH-H questionnaire. According to the results, the mental health of students needs to be strengthened in typical teaching processes, and the preservation and improvement of students' mental health should be in the major focus of attention for all higher education institutions in the future. The results of the study show that mental health has a significant impact on student well-being and consequently influences sustainability. The results of the study will be continuously updated as the survey is conducted every semester.
The Importance of Effective Communication in Lean Transformation Success —Insights From a Hungarian Manufacturing Study
Authors: Kurucz Attila , Buics László
Published: May 2024

With the help of a detailed survey, this article aims to examine how effective communication can aid the lean transformation process within a company. Lean methodologies enable companies to create processes and systems that are so efficient that they give them a significant competitive advantage in the marketplace. On the one hand, these improvements can be made by reducing costs and losses and, on the other, by increasing value to the customer. In this study, a survey was carried out in Hungary among 20 Hungarian companies with lean practices, collecting more than 800 employee responses and focusing on the benefits of lean practices in manufacturing companies. Both managers and employees expressed the same opinion, highlighting the importance of communication in the transformation process. The research was conducted among companies with lean experience, and the results and conclusions described can be applied to the lean implementation projects of Hungarian manufacturing companies. Lean practitioners identified communication as almost as important as team composition and management commitment. The research showed that the success of the transformation depends not only on implementing but also on sustaining and remaining dedicated to change, which is only feasible with the right form and frequency of communication.

The study is based on the assumption that local governments need new guidance in the current global change context. We base our assumption on the fact that the pandemic and the subsequent economic changes have radically altered the external environment of municipalities, which present new challenges, require new marketing management perspectives, and tools to respond. The aim of our research at this stage is to identify and collect the factors and questions that are deemed important by the international researchers of place marketing to discover, identify, and answer in order to provide guidance on how to manage municipalities in the face of environmental change. Building on our preliminary literature review, we conduct a systematic literature review of the questions that have been addressed by researchers in the field of municipal marketing over the past five years. The purpose of this work is to collect, complete, and group the questions so that we can build on the systematic review to develop a model for our further research and to ground our methodological engagement in the methodology of the literature we have identified. Our results show that the focus in the field of place marketing is shifting towards broader perspectives of sustainability.

Backgraound: Date palm disease named Bayoud, is the major constraint caused by the soil fungus Fusarium oxysporum f. sp. albedinis (Foa) in Algeria. This work has the objective to in vivo biocontrol on bayoud disease incidence on three date palm varieties (Deglet-Nour, Feggous and H-mira), using two antagonistic microorganisms, one fungus (Trichoderma harzianum) and one bacterium (Bacillus subtilus). Methods: Foa strains obtained from isolation of the spines carrying the typical symptoms of Bayoud disease. Two strains used T. harzianum and B. subtilus, are isolated from rhizosphere soils of the date palm. Using the greenhouse screening test, the in vivo biocontrol test is carried out on 3-4 month-old date palm seedlings at the rate of 5 ml of inoculum suspension. Result: A significant (P less than 0.01), difference of date palm seedlings reactions against Foa isolate and antagonistic microorganisms was observed. All three date palm varieties present a high susceptibility against Foa until the total mortality of date palm seedlings. The biocontrol test showed that two antagonists showed different reaction, with the complete resistance of three varieties treated by T. harzianum, while, the antagonist B. subtilus protect just two varieties (Deglet-Nour and H-mira) and can’t protect Feggous variety when showed the susceptibility reaction by presentation of typical symptoms of bayoud disease. We can apply of these antagonistic microorganisms to protect our groves contaminated by Bayoud disease and contain just susceptible commercial cultivars of date palm.

Authors: Panigrahi G. , Singh A. N. , Misra O. P.
Published: May 2024

With a view to study the vegetation and flora of the tarai forests and grasslands of the Bahraich district of Uttar Pradesh, bordering upon the tracts of forests in the Nepalese territory, three seasonal tours undertaken in this forest division in March and November, 1964 by the Senior author (G. Panigrahi) and in February, 1965 by O. P. Misra, yielded 530 species of Angiosperms and 14 species of Pteridophytes as represented by 1076 field numbers of plants. (Wherever the name of the Collector is not given between the locality and the field no. in the enumeration appended to this paper, "PANIGRAHI" may be cited).The paper presents an outline of the three classes of forest types viz. Sal, Miscellaneous and Grass and an analysis of the floristic composition in the Katarniaghat-Dharmanpur-Motipur-Doba-Chakia-Chardha and Bhinga forests which are isolated blocks separated by 8-16 km by intervening tracts of cultivation and grazing grounds, except the forests of Dhramanpur and Motipur, which adjoin.The Sal forests are divided into Moist (Gangetic) High level alluvial, dry (Gangetic) alluvial, moist (Gangetic) low level alluvial, dry (Gangetic) alluvial subtypes; the Miscellaneous forests are subdivided into North-Indian Moist Teminalia, Cane brakes, tropical valley fresh water swamp, Khair-babul, Khair-sissoo, North dry-mixed deciduous, Aegle and Gangetic saline scrub; the Grasslands belonging to the lower alluvial moist savannah type and extending over about 37,000 acres, represent the largest of the forest sub-types, discussed below.It has been established that the richness of the grass in the savannah, is not due to the large of different species in the area, but due to the distribution of some species over more stable riverain flats, which are subject to occasional floods and are locally known as PHANTAS.

A Conspectus of the Families Podostemaceae and Tristichaceae
Authors: Subramanyam K. , Sreemadhavan C. P.
Published: May 2024

Recent literature is reviewed and additional evidences presented to support Willis who had split podostemaceae into two families, Podostemaceae sensu stricto and Tristichaceae. In view of the available embryological and anatomical evidences it is suggested that further studies should precede attempts to trace the ancestry of these families to Crassulaceae or Saxifragaceae. Keys and distribution data for the genera of Tristichaceae and Indian Podostemaceae are given.

Taxonomic Revision of the Polypodiaceous Genera of India-Iv Polypodium Lineare Complex and Allied Species
Authors: Bir S. S. , Trikha Chander K.
Published: May 2024

The Asiatic genus Lepisorus (J. Smith) Ching consists of about 25 species, majority of which are known from the Sino-Himalayan region. The present paper deals with the taxonomy of Lepisorus species which belong to Polypodium lineare complex. Our studies have revealed that the Himalayan and South Indian material generally placed under P. lineare is a collection of large and variable types and this material has been sorted out into L. nudus (Hook.) Ching, L. amaurolepida(Sledge).Bir & Trikha, L. bicolor Ching, L. pseudonudus Ching, L. angustus Ching, L. ussuriensis (Regel & Maack) Ching, L. contortus Ching and L. tkunbergianus (Kaulf.) Ching. Out of these L. ussuriensis, L. contortus and L. bicolor are new records from the Indian region. Several of these species are sympatric in distribution and are closely allied in the form of the laminae. These are separable mainly on the basis of the outline and structure of scales and spores.

Studies on the Vascular Flora of Anaimudi and the Surrounding Regions, Kottayam District, Kerala
Authors: Shetty B. V. , Vivekananthan K.
Published: May 2024

The paper deals with an account of the vegetation of Anaimudi (2,695 m) - the highest peak in the peninsular India - and the surrounding regions situated in the Kottayam District of Kerala. The above area has not received much attention in the detailed studies undertaken by various workers on the vegetation of the South Indian hill tops. Based on the explorations carried out by the authors during the years 1965-70, 317 taxa of vascular plants, under 233 genera and 101 families, are enumerated. An analysis of the distribution pattern of the shola and grassland species has shown that (1) the shola species are mainly of tropical stock, (2) quite a number of species on the shola fringes and the grassland are of temperate origin and (3) the temperate elements play a comparatively less important role in the composition of the vegetation at the higher altitudes (above 1,925 m), and that the predominent elements here are of tropical stock. The high incidence of endemic taxa in this region has been pointed out. Literature on the ecological status of the shola-grassland formation has been reviewed for a better understanding of the vegetation.
