Gas Sensing Properties of SnO2-Pd Nanoparticles Thick Film by Applying In Situ Synthesis-Loading Method
Authors: Han Jeong In , Hong Sung-Jei
Published: February 2023

In this study, SnO2-Pd nanoparticles(NPs) were made with an in situ synthesis-loading method. The in situ method is to simultaneously load a catalytic element during the procedure to synthesize SnO2 NPs. SnO2-Pd NPs were synthesized by using the in situ method and were heat-treated at 300 °C. As a result, tetragonal structured SnO2-Pd NPs, having an ultrafine size of less than 10 nm and a uniformly distributed Pd catalyst in the SnO2 lattice, were well made and a gas sensitive thick film with a thickness of c.a. 40 μm was well fabricated by using the NPs. Gas sensing characterization for CH4 gas indicated that the gas sensitivity, R3500/R1000, of the thick film consistent with SnO2-Pd NPs synthesized with the in situ synthesis-loading method, followed by heat-treatment at 500 °C, was enhanced to 0.59. Therefore, the in situ synthesis-loading method is available for synthesis of SnO2-Pd NPs for gas sensitive thick film.

Authors: Lee Miran , Wei Qun , Lee Soomin , Park Heejoon
Published: February 2023

A sudden cardiac event in patients with heart disease can lead to a heart attack in extreme cases. Therefore, prompt interventions for the particular heart situation and periodic monitoring are critical. This study focuses on a heart sound analysis method that can be monitored daily using multimodal signals acquired with wearable devices. The dual deterministic model-based heart sound analysis is designed in a parallel structure that uses two bio-signals (PCG and PPG signals) related to the heartbeat, enabling more accurate heart sound identification. The experimental results show promising performance of the proposed Model III (DDM-HSA with window and envelope filter), which had the highest performance, and S1 and S2 showed average accuracy (unit: %) of 95.39 (±2.14) and 92.55 (±3.74), respectively. The findings of this study are anticipated to provide improved technology to detect heart sounds and analyze cardiac activities using only bio-signals that can be measured using wearable devices in a mobile environment.

Authors: Conti Stefania , Dias Álvaro , Pereira Leandro
Published: February 2023

The focus on the sustainability of tourism destinations and firms is a global trend. However, the implications of those investments in tourist behavioural intentions need further investigation. This study proposes a conceptual framework for exploring the influence of sustainability perceptions and travel behaviour on the intention to recommend and revisit. The results from structural equation modelling and importance–performance matrix analysis show a direct relationship between travel behaviour and perceived sustainability. Additionally, it shows a direct relationship between travel behaviour and perceived value, corroborating previous research on green tourists. By increasing perceived sustainability, managers and marketers can enhance their sustainability strategies based on tourists’ feedback and market the destination to more specific targets via tailored communication. Sustainability perceptions were also found to be a key driver of satisfaction and to have indirect consequences on behavioural intentions of loyalty, representing the ultimate goal of a destination.
Synergistically Enhanced Oxygen Evolution Catalysis with Surface Modified Halloysite Nanotube
Authors: Jeong Hyeongwon , Sharma Bharat , Myung Jae-ha
Published: February 2023

Synergistically increased oxygen evolution reaction (OER) of manganese oxide (MnO2) catalyst is introduced with surface-modified halloysite nanotube (Fe3O4-HNTs) structure. The flake shaped MnO2 catalyst is attached on the nanotube template (Fe3O4-HNTs) by series of wet chemical and hydrothermal method. The strong interaction between MnO2 and Fe3O4-HNTs maximized active surface area and inter-connectivity for festinate charge transfer reaction for OER. The synergistical effect between Fe3O4 layer and MnO2 catalyst enhance the Mn3+/Mn4+ ratio by partial replacement of Mn ions with Fe. The relatively increased Mn3+/Mn4+ ratio on MnO2@FHNTs induced σ* orbital (eg) occupation close to single electron, improving the OER performances. The MnO2@FHNTs catalyst exhibited the reduced overpotential of 0.42 V (E vs. RHE) at 10 mA/cm2 and Tafel slope of (99 mV/dec), compared with that of MnO2 with unmodified HNTs (0.65 V, 219 mV/dec) and pristine MnO2 (0.53 V, 205 mV/dec). The present study provides simple and innovative method to fabricate nano fiberized OER catalyst for a broad application of energy conversion and storage systems.
Propozycja Stanowiska Europejskiego Urzędu Nadzoru Ubezpieczeń i Pracowniczych Programów Emerytalnych w sprawie zróżnicowanych praktyk cenowych w ubezpieczeniach innych niż na życie – soft law w wersji hard?

Niniejszy artykuł jest poświęcony analizie prawnej i ocenie przedłożonej do konsultacji w lipcu 2022 roku propozycji Stanowiska Europejskiego Urzędu Nadzoru Ubezpieczeń i Pracowniczych Programów Emerytalnych w sprawie zróżnicowanych praktyk cenowych w ubezpieczeniach innych niż na życie. Choć formalnie Stanowisko stanowi akt prawa miękkiego o charakterze nienormatywnym i niewiążącym, to w praktyce nakreślone w nim oczekiwania wobec państw członkowskich i krajowych organów nadzoru nad rynkiem ubezpieczeniowym wykraczają – jak się wydaje – poza ramy dopuszczalnej regulacji dokonywanej w drodze instrumentów typu soft law.
Resolution w sektorze ubezpieczeniowym – przesłanki, modelowe rozwiązania i wyzwania
Authors: Kozińśka Magdalena
Published: February 2023

Analiza systemu zarządzania kryzysowego w sektorze ubezpieczeniowym wskazuje, że konieczne jest jego wzmocnienie. Najważniejszymi brakującymi elementami są szerokie uprawnienia organów publicznych, źródła finansowania działań antykryzysowych, jak również zasady współpracy międzynarodowej w czasie kryzysu. Odpowiedzią na identyfikowane braki jest procedura resolution, której wprowadzenie planowane jest w UE, co jest zgodne z rekomendacjami międzynarodowymi. Elementami koniecznymi systemu resolution w sektorze ubezpieczeniowym są: powołanie organów resolution, wyposażenie organów resolution w szeroki katalog uprawnień zapewniających możliwość wdrożenia narzędzi resolution, obowiązek przygotowywania planów resolution, ustanowienie ram finansowania resolution oraz ustanowienie ram zarządzania kryzysowego w ujęciu transgranicznym. Wprowadzenie ram resolution wiązać się będzie jednak z wieloma wyzwaniami na etapie ich uzgadniania na poziomie UE, ich tworzenia na poziomie krajowym oraz przygotowania ubezpieczycieli do rozszerzenia zakresu kompetencji sieci bezpieczeństwa finansowego.
Les stèles anthropomorphes de la Bastidonne (Trets, Bouches-du-Rhône) et leur contexte du Néolithique moyen

Published: February 2023

La plaine de Trets, en limite orientale des Bouches-du-Rhône, recèle un grand nombre de sites néolithiques. Dans les années 1870, après un labour, celui de la Bastidonne livra un très abondant mobilier archéologique ainsi que quinze fragments de stèles décorées. L’ensemble des vestiges était mêlé à de possibles restes de crémations mais il règne depuis toujours une grande confusion quant à la position exacte des fragments de stèles au moment de la découverte. D’autres plus petits fragments ont été récoltés par la suite. Bien qu’elles constituent le plus riche regroupement connu dans le Sud-Est de la France, les stèles néolithiques de la Bastidonne n’ont que rarement fait l’objet de descriptions systématiques dans leur contexte. Réalisées dans un calcaire local, elles étaient de forme trapézoïdale ou triangulaire et ne mesuraient pas plus de quelques dizaines de centimètres de haut. Les fragments affichent un décor géométrique gravé et sculpté. La représentation schématique du visage se limite dans la plupart des cas à une plage creuse et lisse, subrectangulaire. En outre, d’importantes traces de pigment rouge ont été décelées dès la fin du XIXe siècle. Celles-ci ne présentent pas d’organisation particulière et l’ensemble de la face décorée de même que les chants devaient être ainsi badigeonnés. Les récentes analyses ont montré qu’il s’agit de cinabre. Le mobilier lithique récolté à la Bastidonne ainsi qu’à Sainte-Catherine – une station située à moins d’un kilomètre et qui a pu appartenir au même ensemble – doit être attribué à une étape récente du Néolithique moyen. Si l’on ajoute à cela les dates radiocarbones d’une nouvelle découverte dans les Alpes-de-Haute-Provence, les stèles de la Bastidonne, comme l’ensemble des quelques cinquante stèles ou fragments de stèles du sous-groupe provençal à chevrons, apparaissent comme l’une des plus anciennes manifestations d’art statuaire anthropomorphe de Méditerranée occidentale, entre 3900 et 3600 av. J.-C. environ.
Variabilité des productions lithiques de la basse vallée du Rhône au Néolithique ancien
Authors: Defranould Elsa
Published: February 2023

L’implantation des premières sociétés agropastorales dans le sud de la France semble marquée par un important polymorphisme culturel et une variabilité des stratégies d’implantation. La sphère cardiale correspond à une étape d’importante expansion territoriale des groupes humains, datée entre 5600 et 4800 avant notre ère. Historiquement, cette vaste entité chronoculturelle a été appréhendée et divisée en plusieurs faciès, Cardial et Épicardial, sur la base des données céramiques. Cette étude propose d’étudier ce complexe par un autre pan de la culture matérielle, celui de la confection des outillages en pierre taillée. Pour cela, une zone d’étude centrée sur la basse vallée du Rhône constitue une fenêtre idéale pour aborder la variabilité des productions lithiques de la sphère cardiale. Le coeur de l’étude se base sur l’analyse de huit assemblages de pierres taillées du Gard et de l’Ardèche, mais également sur une documentation abondante et renouvelée, qui concerne les données céramiques, chronométriques et dans une moindre mesure des industries lithiques. Ce cadre permet de discuter finement de la variabilité techno-économique des productions lithiques au cours du temps. L’article pose dans un premier temps le contexte chronoculturel des différentes séries du corpus (assemblages directement étudiés ou publiés) et leur attribution à des faciès céramique. L’étude présente ensuite quelques éléments permettant la restitution des schémas opératoires des différents assemblages. Ceux-ci associent une production plutôt expédiente d’éclats débités à la percussion directe dure à une chaîne opératoire laminaire plus aboutie, obtenue par percussion indirecte. Malgré la pérennité de ce schéma opératoire tout au long de la séquence chronologique, plusieurs variations techno-économiques, et dans une moindre mesure typologiques, peuvent être mises en évidence. Les césures observées ne sont pas les mêmes que celles identifiées par les données céramiques. Ces résultats permettent alors de discuter de l’organisation géographique des sociétés cardiales et épicardiales, en particulier à partir de l’hypothèse d’une mise en place d’un réseau de circulation de lames en silex de bonne qualité aux alentours de 5200 cal. BC.
Changements sociétaux et évolution de l'économie du fer du Hallstatt D à La Tène D dans le Nord-Est de la France
Authors: Berranger Marion , Bauvais Sylvain
Published: February 2023

Les âges du Fer en Europe nord-occidentale voient la diffusion et l’adoption progressive du fer, puis une succession d’innovations majeures dans les techniques de sa production. Les procédés de fabrication d’objet se démocratisent, tandis que la consommation des objets s’intensifie et gagne l’ensemble des strates sociales. La maîtrise des productions métallurgiques est considérée de manière récurrente comme un des moteurs de l’émergence des centres de pouvoirs. Nous proposons d’analyser ce postulat à l’aune d’un bilan renouvelé de nos connaissances sur la métallurgie du fer en prenant en compte un large espace correspondant au Nord-Est de la France actuelle. Cela inclut les zones où se manifestent de manière ostentatoire les élites du premier et du début du second âge du Fer, puis l’armement et l’art

celtique florissant de La Tène moyenne. Pour la fin de l’âge du Fer, cet espace est également caractérisé par l’émergence de nouvelles formes de manifestations urbaines. À travers une grille de lecture structurée, composée de critères descriptifs issus de la littérature (Brun et al., 2006 ; Roux, 2000 ; Costin, 1991), nous proposons d’étudier les formes d’organisation des productions sidérurgiques et leur évolution au cours des âges du Fer. Il est ainsi possible de constater les trajectoires différentes suivies par les activités de réduction et de forgeage tout au long de cette période. Elles se développent durant le Hallstatt D – La Tène A sous

contrôle des élites. Cela mobilise, pour les activités de production de fer brut des savoir-faire simples, alors que les productions en forge documentent au contraire la maîtrise de techniques complexes évoquant un art de cours. À la fin des âges du Fer, les élites conservent leur emprise sur les moyens de production de centres de réduction fortement structurés, alors qu’à l’inverse, en forge, l’élargissement de la gamme des savoir-faire et la multiplicité des modes d’organisation permettent de reconnaître un artisanat maître de ses débouchés.

Published: February 2023

This study aims to determine the performance of a plastic mulch hole making machine and its electrical power requirements. The study begins by providing speed variations on the engine sprocket, calculating the working capacity of the machine, and analysing the power requirements of the electric motor. The results showed that the engine sprocket could perform an optimal rotation speed for punching holes in plastic mulch. Most holes were created in the treatment with a rotational speed of 70 rpm, 16 holes per 5 m of plastic mulch. Overall, the performance of the plastic mulch punching machine has been able to provide fixes in making holes in mulch plastic. Of the three treatments, the speed variations of the plastic mulch punching machine provided perforations with the criteria of perfect and partial perforation. The highest percentage of ideal perforation was found in the treatment with a rotational speed of 29 rpm, 86%, and the lowest was found in the treatment with a rotational speed of 25 rpm, 9.3%. The coefficient of determination between the rotational speed of the machine and the performance of the machine to punch holes in the plastic mulch can be modelled by a polynomial equation.

Published: February 2023

Rice is one of the important crops and staple food for millions of people in India and world. In India, it is cultivated in 45.07 million ha which is largest area under rice cultivation in the world. However, the productivity of rice in India is less in comparison to Egypt and China. Rice crop is cultivated by conventional practices in India. These practices require high inputs which adversely affects the natural resources i.e. soil, water and climate in the form of soil degradation, ground water depletion and air pollution. Rice farming is negatively affected by these environmental degenerative factors. The development and adoption of new technologies are imperative to reduce these environmental degenerative factors of rice farming. These technologies enhance the production by efficient and precise application of inputs such as seed, fertilizer, chemicals and irrigation water. It ultimately lowers the cost of production. The aim of this paper is to provide information about available improved machineries and technologies for pre-harvest operations of rice crop. The high capacity machinery such as rice transplanters, combines, etc are to be used on custom hiring and for contractual field operations. There is a need for assured mechanised services to farmers and guaranteed business to service providers for paddy nursery raising, mechanised transplanting and combine harvesting.

Published: February 2023

Rice plays very important role in food and nutritional security in the developing world. Although India is the second largest producer (113 mt) next to China with 44 mha area under rice, its average yield (~2.6 t/ha) is far below both that of China (>6 t/ha) and the global average of ~4 t/ha. Hence, along with genetic enhancement and advance crop protective measures, innovative extension approaches with agro-ecological importance, geo-political, socio-economic can support to improve the rice productivity levels with climate resilience and effective natural resources management perspectives. Moreover, the agricultural extension paradigm shift from National demonstration in 1960's to Training and visit system in 1970's to pluralistic extension approaches in 1990's has enhanced the rice production from 34.5 million tonnes in 1960-1961 to 117.5 million tonnes in 2020-2021. Still there is a huge potential to transform the rice production systems of the country through adoption of bottom-up innovative extension approaches with information and communication connectivity. Approaches like social learning, community engagement and ICT support have proven effective in dissemination and adoption of improved varieties and practices of paddy cultivation.

Published: February 2023

Introduction. In the conditions of full-scale russian aggression, the threat of a financial crisis in Ukraine is growing, the risk of the functioning of business entities is increasing, therefore it is extremely important to strengthen the economic potential of our state. Due to the martial law and the introduction of a curfew, the logistics between counterparties has significantly worsened, which reduces the turnover of sales and purchases and negatively affects all indicators of the enterprise. The uncontrolled growth of accounts payable for goods, works, and services in the conditions of the existing problem of non-payments may become even larger. Therefore, one of the important tasks in the conditions of their occurrence is the systematic analysis of the company's payables, as a factor of ensuring business continuity, a basic assumption in the concept of accounting.
Purpose. The purpose of the work is to study the influence of accounts payable on ensuring the continuity of business activities on the basis of a system of analytical indicators, cluster analysis, which is extremely important in the conditions of martial law.
Method (methodology). To achieve the goal, general scientific, economic and mathematical methods and approaches, analytical procedures and tools were used, in particular, horizontal and vertical analysis, cluster analysis, formalization and generalization of the influence of accounts payable on ensuring continuous activity in the conditions of martial law.
The results. The impact of commercial payables on ensuring business continuity under martial law conditions has been studied. The introduction into the theory and practice of accounting analysis as a component of economic analysis of economic activity (business) based on the additional involvement of accounting information, which is not directly reflected in financial statements, is argued. It is proposed to use a system of indicators, procedures for analytical justification of management decisions, focused on the implementation of business continuity.
The new energy model of post-war Ukraine: distributed generation and the electricity exchange market
Authors: Sokhatska Olena , Panasyuk Valentyna
Published: February 2023

Introduction. The task of Russia as an aggressor country during a large-scale war is to destroy the statehood of Ukraine, which is accompanied by the genocide of the population due to the destruction of critical life support infrastructure, in particular, facilities for generating electricity and transmitting it to consumers. As of the end of 2022, as a result of massive missile attacks, more than 50% of energy capacities have been destroyed, which in turn leads to long-term emergency power outages for household consumers and businesses. Such significant damage was caused by the legacy of the USSR model of centralized generation at several nuclear, thermal and hydroelectric power stations. Ukraine's signing of the Association Agreement with the EU provided for the reform of the energy sector, but centralization and monopolization did not allow the planned implementation, in particular, the formation of an electricity market with transparent exchange pricing mechanisms for this resource.
The purpose. Based on the analysis of foreign experience, develop recommendations for the formation of a new energy model of post-war Ukraine.
Methods. In the process of research, methods of analysis and synthesis, generalization and comparison, benchmarking was used to find the best foreign practices. It was revealed that the processes of distribution of electricity generation have been taking place on the energy market of EU countries for a long time, which increases the number of participants and contributes to the formation of exchange mechanisms for transparent pricing of this resource.
The results. It has been proven that the restoration of the existing centralized generation will not solve the issue of energy security of the country in the future. It is proposed to include the formation of a new energy model based on the decentralization (distribution) of generation based on new environmentally friendly technologies and the electricity exchange market as part of Ukraine's post-war reconstruction strategies.
The relevance of using ABC inventory analysis in profitability management of the enterprise with the purpose of optimizing working capital
Authors: Zamazii Oksana
Published: February 2023

Introduction. The competition of goods and services increasingly goes beyond the market nowadays and is transformed into competition of enterprises for consumers. The consumer forms the volume of sales of the company's products, and as a result, this leads to an increase in its income and profitability. In turn, the company must maintain the appropriate amount of working capital - trade stocks, stocks, resources, because their excess makes the company inert, and the disadvantage - leads to a violation of the normal production process and opportunities for increasing sales volumes. Therefore, maintaining the optimal amount of working capital is one of the important problems of managing the company's current assets.
Purpose. The purpose of the study is to study the possibilities of forming the optimal structure of commodity stocks, as one of the components of the Goal. The purpose of the study is to study the possibilities of forming the optimal structure of commodity stocks, as one of the components of the working capital of the enterprise. enterprises.
Method. Scientific works on the analysis and management of the company's working capital are the methodological basis of the research. An example of the practical application of the ABC analysis method is given. This method is indispensable when forming the nomenclature of goods (product range) and their stocks, which make up the most specific weight in the structure of the working capital of the enterprise. The formation of the stages of the ABC analysis allows you to clearly demonstrate the order of choosing the most important factors when making a management decision regarding the optimal structure of the working capital of the enterprise. The versatility of this ABC analysis method is emphasized. It seems appropriate to note that such an economic category as the consumer value of the product, which directly affects the size of the company's reserves and the working capital of the company, can be analyzed using this method.
The results. The adaptability of the ABC analysis to the industry specifics of the business entity and to the specified task of managing the production and economic process of the enterprise is considered. On the basis of empirical studies given in the example, the ratio of groups A, B and C according to the criterion of sales value is demonstrated. The expediency of using the results of ABC analysis in the formation of the optimal structure of working capital in the part of goods is substantiated on the example of a trading company. The practical implementation of ABC analysis will allow to form an appropriate information and analytical base for the formation of effective management actions aimed at increasing the production capacity of the enterprise and increasing its profit.

The research emphasizes the relevance of the formation and implementation of the state policy of stimulating the development and realization of the potential of high-tech startups in the field of information and communication technologies. It is argued that their activation is an integral prerequisite for both the technological modernization of the national economy and the digital transformation of the economy and society of each country.
It is shown that the globalization changes of the world economy are taking place with the active expansion of the fields of application of information technologies, and the inability of countries to accept such trends leads to their economic slowdown and loss of opportunities to develop competitive advantages. The purpose of the study is to generalize and develop the theoretical and methodological foundations of state regulation in terms of stimulating the activation and supporting the development of high-tech startups in the field of information and communication technologies.
The results of scientific research on the systematization of mechanisms, tools and means of forming the state policy of supporting high-tech start-ups in the sector of information and communication technologies are summarized. In particular, the role and significance of such mechanisms of state policy as organizational, economic, institutional-legal, institutional-organizational, social, psychological are shown.
The theoretical and methodological provisions for the formation and implementation of the organizational and economic mechanism for the implementation of the state policy of supporting high-tech start-ups in the field of information and communication technologies have been developed. It was concluded that the theoretical-methodical and theoretical-practical basis of the organizational-economic mechanism of implementing the state policy of supporting high-tech start-ups in the field of ICT involves a complex coordinated combination of tools, means and measures.
At the same time, the main task of state policy in this area is the formation of a favorable environment for the development, activation and efficiency of the activities of high-tech startups, as well as the implementation of organizational and management functions for managing the relevant processes.

), and observe (i) a growth rate increase, (ii) an expanded growth window, and (iii) reduced out-of-plane mosaic spread when MOCATAXY is employed for the growth of α-Ga2O3. Through the use of In-mediated catalysis, growth rates over 0.2 μm h−1 and rocking curves with full width at half maxima of Δω ≈ 0.45° are achieved. Faceting is observed along the α-Ga2O3 film surface and explored through scanning transmission electron microscopy.

In this work, the insertion of AlScN ferroelectric gate dielectric on the performance of the AlGaN/GaN HEMT device is investigated. With negative pre-poling on AlScN, the threshold voltage (V
th) of the device shifts positively with a swing range of 3.26 V. The influence of polarization modulation is also reflected by the suppression of gate leakage and the reduction of the subthreshold swing of the device. The AlScN-integrated GaN HEMT exhibits an on/off ratio of 106 and a subthreshold swing of 80 mV dec−1. The depletion mechanism of 2DEG at the AlGaN/GaN interface was well described by a TCAD model.

Published: February 2023

A Restricted Selection Index was constructed to genetically evaluate animals using a dataset composed of body weights of Shami kids at the ages of birth, weaning, and 6-month. The variance-covariance matrix (VCV) was generated and used to estimate genetic parameters for the index construction after adjusting the fixed effects; year, birth month, kid sex, type (single, twin or triplet) of birth, doe age, weights at kidding (KW), birth (BWT) and weaning (WWT) as covariates. General Linear Model and Restricted Maximum Likelihood methods were used to estimate BLUE for fixed effects and variance components for random effects, respectively. BW was 3.6 ± 0.017, WW 16.8 ± 0.10, and weight at 6 months (MWT) was 26.7 ± 0.21 Kg. With the exception of buck origin and doe age, all tested factors significantly affected growth traits. Heritability for BWT, WWT, and MWT was 0.70 ± 0.10, 0.32 ± 0.075, and 0.41 ± 0.12, and repeatability was 0.78, 0.35, and 0.47, respectively. Genetic and phenotypic correlations were positive and significant between BWT and WWT, and between WWT and MWT. The restricted selection index constructed for increasing weights at MWT and WWT with restriction on BWT yielded a strong correlation coefficient (rIA) between the genetic merit and the index at 0.54 (p<0.01).
