Authors: Šain Marija , Buljubašić iva , Mihaljević Vlatka
Published: November 2023

This paper analyzes the importance and use of marketing for fundraising in the cultural sector. Namely, due to limited public financial resources and social changes in general, the cultural sector should turn to the market and to new sources of financing and implement a fundraising strategy. Activities are needed to attract financial resources from various sources to ensure the income necessary for its operation and sustainability. To be successful in fundraising and ensure stable business, the cultural sector needs to implement various activities that are usually associated with the profit sector (planning, management, marketing, analysis), which also includes an entrepreneurial way of thinking and acting. This paper aims is to identify the role of marketing in fundraising and the effectiveness of marketing strategies for the success of fundraising in cultural institutions. Empirical research was conducted on cultural institutions in the Republic of Croatia with an emphasis on the use of unconventional marketing for fundraising purposes. The conclusion is that this type of marketing affects the successful collection of funds and, ultimately, the success of the business and the financial result of the cultural institution. The results of the research indicate that it is necessary to implement an appropriate marketing strategy for the purpose of successful fundraising, as well as to educate the employees of cultural institutions in the field of marketing and fundraising.
THE ROLE OF POPULAR SONGS IN CONFIRMING CROATIAN NATIONAL IDENTITY
Authors: Škojo Tihana , Drenjančević Zdravko
Published: November 2023

The experiential, emotional reception of a piece of music depends on a number of factors. Considering this complex phenomenon from a subjective aspect, the individual experience of a particular piece of music is influenced by the time and place of listening, as well as by physical and social factors, structural elements of the music, and other qualitative elements. Popular music, due to its distinctive features, which are manifested through a simpler melodic and rhythmic structure, elicits an intense emotional response from the listener even at the first listening. The textual element plays a significant role in this, as it can completely change the affective valence of the piece of music. Based on the musical analysis of nine popular songs from the Homeland War, the most intensive period in Croatian history in social and political terms, the paper discusses all the experiential elements that influenced the emotional reception and the popularity of these songs. The impact of lyrics on the affective dimension of the acceptance of the songs is highlighted, as is the setting in which they were composed and the significance they had for the formation of national identity.

Corpo, cidade e imagem: pensando práticas educativas no campo das artes
Authors: Araújo Pedro Simon Gonçalves
Published: November 2023

O presente artigo apresenta reflexões de uma experiência pedagógico-afetiva realizada durante minha pesquisa de doutorado, realizada entre os anos de 2018 e 2022. A partir da articulação entre os conceitos de memória, imagem, corpo e cidade realizo com alunos do curso de licenciatura em dança do Instituto Federal de Goiás uma investigação de cunho qualitativo, que encontra na abordagem narrativa (auto)biográfica bases para o seu desenvolvimento. Ancorado nos princípios da educação da cultura visual, teço uma escrita que estabelece relações dialógicas com imagens e saberes estético-afetivos vinculados à dança, colocando em perspectiva subjetividades e potências do corpo em espaços de ensino. Discuto modos como o corpo pode ser afetado por imagens da cidade, buscando compreender de que maneira esses atravessamentos impactam a formação de indivíduos e geram aprendizados por meio do movimento e da performance, intensificando as percepções de si e apropriações pedagógicas de espaços dentro e fora das escolas. Os resultados do estudo revelam uma composição de saberes sensíveis dos indivíduos sobre si mesmos a partir do corpo em movimento e de conexões com memórias e episódios de suas histórias de vida. Demonstram, ainda, a possibilidade do uso de imagens na relação entre corpos e cidades através da performance/dança, projetando potencialidades de apropriação e uso do espaço público.

Authors:   Associate Professor Department of English, Government College for Women, Hisar, Singla Priyanka
Published: November 2023

Amitav Ghosh’s The Glass Palace is widely regarded as one of the essential historical novels of the last century. This paper explores the importance of The Glass Palace as a historical novel and why it remains relevant today. The novel allows readers to see imperialism’s devastating effects on individual lives and communities. It captures the cultural and psychological tensions of colonialism in one of the central locations it affected, Burma. Furthermore, The Glass Palace’s significance as a historical novel stem from its detailed portrayal of the social, economic, and political situation of the time. By presenting historical events in an entertaining, engaging way or with fictional characters, Ghosh makes his reader cull information from one of the more enthralling telling of Asian history.

Numerical investigation of heat and mass transfer of variable viscosity Casson nanofluid flow through a microchannel filled with a porous medium
Authors: Enyadene Lemi Guta , Rikitu Ebba Hindebu , Gabissa Adugna Fita
Published: November 2023

Thermal behaviours and hydrodynamics of non-Newtonian nanofluids flow through permeable microchannels have large scale utilizations in industries, engineering, and biomedicine. Therefore, this paper presents the numerical investigation of heat and mass transfer of variable-viscosity Casson nanofluid flow through a porous medium microchannel with the Cattaneo-Christov heat flux theory. The highly nonlinear PDEs corresponding to the continuity, momentum, energy, and concentration equations are formulated and solved numerically via the second-order implicit finite difference scheme known as the Keller-Box method. Accordingly, the numerical simulations reveal that the variable viscosity parameter, thermal Grashof number, solutal Grashof number, thermophoresis parameter, Schmidt number, and Casson fluid parameter show increasing effects on both velocity and temperature of the nanofluid. Furthermore, the temperature profile escalates with increasing values of the Eckert number and the thermal relaxation time parameter. Thus, the Cattaneo-Christov heat flux model is beneficial in warming the transport system of microfluidics when compared to that of the classical Fourier heat conduction law. The temperature profile, however, indicates a retarding behavior with increasing values of the Brownian motion parameter, Prandtl number, and porous medium parameters, namely the Forchheimer number and porous medium shape parameter, and hence, the porous medium quite effectively controls the nanofluid temperature distribution, which plays substantial roles in cooling the transport system of microfluidics. Moreover, the concentration profile shows an increasing pattern with escalating values of the Prandtl number, Schmidt number, and thermophoresis parameter, but it demonstrates a decreasing trend with the Casson fluid, variable viscosity, thermal relaxation time, and solutal relaxation time parameters. It is also observed that the coefficient of skin friction increases with increasing values of the pressure gradient parameter, Eckert number, Forchheimer number, and injection/suction Reynolds number. Besides, the heat transfer rate at both walls of the microchannel increases with rising values of the Eckert number, variable viscosity, parameter, and injection/suction Reynolds number. The Casson fluid and thermal relaxation time parameters reveal opposite scenarios for the heat transfer rate at the left and right walls of the microchannel. In addition
the mass transfer rate at both walls of the microchannel shows an increasing pattern as the Eckert number, variable viscosity parameter, Schmidt number, and suction/injection Reynolds number increase.

The history of the global economy is the history of global international trade; whoever could command the oceans could control the wealth of that Era, e.g., Phoenicians and Arabs commanded the world before Europe’s colonial expeditions through seas. When the Cold War Bipolar Era ended, the USA has been enjoying the benefits of globalization through military presence and hegemony across oceans in the unipolar Era. The Indian Ocean is said to contain most of the significant sea trade routes of the world, and the Bay of Bengal in the Northeast does the same more precisely while interfacing with the South China sea. Regional peace and stability is a precondition for the sustainability of international maritime trade and other blue economic functions. Here, this research is to propose region specific COMR (comprehensive ocean management regime) model to achieve blue economic objectives sustainably for the BOB (Bay of Bengal) maritime-littoral region. This research examined coastal and ocean initiatives like Maritime Protected Areas and Integrated Coastal Zone Management for their challenges at policy, management and operation levels leading towards a conceivable solution, choosing to make a few insinuations to the nations and areas of the world. Sectoral data that has been aggregated might be confusing, and quantitative data lacks validity and precision. In an outcome, in the deficiency of quantitative data, the presentation is created qualitatively. Moreover, the study also uses the Delphi method to address the research objectives of this study because, to establish a consensus, the Delphi technique includes obtaining expert opinion through a series of progressive and iterative investigations.

Authors:   Livestock Research and Development Center, Capiz State University Pontevedra, Capiz, Philippines 5802, J. Escala Emely
Published: November 2023

The purpose of this study was to evaluate the chemical composition and changes in the surface structure of rice straw as affected by the number of days of exposure to the field prior to processing. A total of 24 packs of rice straw samples collected at 1 day after threshing (DAT), 4 DAT, and 7 DAT field exposure untreated and treated with urea for 10 days were analyzed for its chemical changes using proximate analysis and surface structure of the fiber compounds through scanning electron microscopy (SEM). Results (%DM basis) showed that 1DAT untreated rice straw obtained the highest dry matter (DM) concentration at 94.61%. Seven DAT untreated rice straw contain the highest amount of Ash at 20.92%. Likewise, 1 DAT and 7 DAT untreated rice straw contains higher levels of crude protein (CP) at 9.60% and 9.79%, respectively. Ether extract (EE) was observed highest in 1DAT untreated rice straw at 1.97%. Considerable breakdown of cellulose, hemicellulose, and lignin fractions of rice straw was attained in 4DAT and 7DAT untreated, and 1 to 7 DAT urea-treated rice straw (UTRS) as evident by its lower NDF, ADF, and ADL values. Changes in the surface structures of microfibers efficiently captured using SEM showed the differences in the morphology of the fibers as influenced by number of days exposed to the field prior to treatment. Therefore, in order to optimize the protocol to improve the feeding and nutritional quality of rice straw, it is suggested that the number of days of exposure to the field be considered prior to processing. Likewise, UTRS is an effective method to disintegrate the complex fibrous compounds of the cell wall of rice straw.

In this paper, a comparative analysis of the service life of worm gear wheels for various failure criteria is carried out. Based on this analysis, a method is proposed for selecting the worm gear wheel material, the values of the modulus, on which the bending strength of the teeth depends. Research has shown that increasing the bending strength of teeth is of great practical importance, both for one-sided and two-sided loads. This also makes it possible to significantly increase the lifetime of one-side loaded gear wheels by replacing their working flanks with non-working ones. it was proposed to replace the working surfaces of the teeth of worm wheels after a certain service life.

Glucosodiene, a novel compound synthesized through the reaction between dextrose and sodium bicarbonate, is explored in this study. The main objective was to investigate its potential as a cancer-targeting agent by inhibiting glucose metabolism within tumors, also known as the Warburg effect. Previous studies have demonstrated its impact and safety in laboratory and human applications. However, the chemical and stereochemical formula of glucosodiene has not been confirmed. In this manuscript, we present the NMR and LC-MS results of the synthesized glucosodiene Polymer and describe the optimized method for its preparation. The reaction between dextrose and sodium bicarbonate resulted in the formation of glucosodiene, a Polymer compound with a similar structure to glucose. The NMR analysis confirmed the presence of the formula C12H22O11, while LC-MS results validated its identity as 1-2-O-β-D-Glucopyranosy l-α-D-glucose. Glucosodiene is composed of monomers derived from glucose isomers connected through 1-2 linkages, represented as (1-2-O-β-D-Glucopyranosyl-α-D-glucose). The monomer’s molecular mass is determined to be 178.9, and it shares structural similarities with trehalose but forms the polymer through self-association, resembling the molecular structure of sophorose.

Among different piston rings of an Internal Combustion Engine (IC), the top compression ring-liner assembly shared a momentous amount of the total frictional losses, particularly at the Top Dead Center (TDC) and Bottom Dead Center (BDC) where boundary lubrication subsists. In the present study, the lubrication mechanism in piston ring cylinder liner conjunction for top compression ring using one dimensional Reynolds equation assuming axisymmetric contact was studied. The hydrodynamic and mixed lubrication regimes were taken during the study. Gumbel boundary conditions were used for Reynolds equation solution. For boundary pressure calculation, first, combustion chamber pressure variation was determined, then, interring pressure was calculated assuming orifice volume method by solving mass flow rate through crevice volumes using Runge-Kutta 4th order method. The Reynolds equation was solved using finite difference method. Whole solution process was repeated for different engine speed and crown height of top compression ring to study the effect of them in wear and power loss. First, the solution was found for 3000, 5000 and 7500 RPM keeping constant crown height of 10 µm. Average power loss was found to be increased with the increasing engine speed. There was increased in oil film thickness around mid-stroke with the increased engine speed, but there was no significant change in film thickness with the engine speed at the TDC and BDC positions. Then, the solution was again repeated for different RPM varying the crown height. The compression ring with lower crown height showed the better wear performance by increasing the minimum film thickness in critical zones of engine cycle for all RPM. The crown height of 5,7 and 9 µm gave the minimum power loss (77.89, 163.47 and 297.33 W) for 3000, 5000 and 7500 rpm. Moreover, the power loss in the range of 5-9 µm had no significant differences.
How to Apply A Strategic Approach to Deliver Legacies from Hosting Mega Sport Events
Authors: Dickson Tracey J.
Published: November 2023

In the process of bidding for and organizing mega sport events (e.g., Olympics, Paralympics, and FIFA World Cups), there are many opportunities to leave a legacy for the host communities. The more obvious legacies are new stadiums, better transport, and urban redevelopment. Less obvious legacies are increased sport participation and enhanced volunteering activity. There is little research after the events that demonstrate these legacies. This Research Report is informed by recent research that highlights the lack of strategic planning for legacies. To outline how a host community could increase their chances of delivering legacies after hosting mega sport events this paper applies a common business approach, strategic management.
Comparing Generation Y Hotel Employees in the United States and China
Authors: Knutson Bonnie , Kim MiRan
Published: November 2023

Millennials will represent 75% of the global workforce by 2025. They were born and raised in an era of rapid technological development, better access to education, and growing globalization. They are often characterized as protected by Baby Boomer parents and society. They are technologically-savvy, achievement-oriented, team-oriented, job-hoppers, and focused on life-balance. It is essential to understand their values in term of work attitudes and behaviors. Employees’ commitment to customer service is particularly important in the hotel sector as it results in greater customer satisfaction and loyalty as well as better service quality. We surveyed hotel employees in the United States and China to see if they might differ in terms of their work attitude and behaviors. Millennial employees in both cultures expressed a solid commitment to customer service and their attitudes towards power distance, empowerment, employee voice, and team member exchange were similar. The distinct difference was considering how these factors might predict employees’ commitment to customer service, where team member exchange was the most significant predictor for U. S. employees while employee voice was the most significant predictor for the Chinese hotel employees. The findings of this study will help hotel managers understand Generation Y’s values in term of work attitudes and behaviors in a cross-cultural workplace.

Biophysical evaluation of the effectiveness of high-frequency bipolar electric welding for closing defects in the dura mater in frontal sinus tumours with intracranial spread
Authors: Zabolotnyi Dmytro , Kvasha Olena
Published: November 2023

One of the main tasks of surgical treatment of patients with frontal sinus neoplasms with intracranial spread is to seal the subdural space, which is achieved by hermetically connected dura mater. The purpose of this study was to investigate the structure of the tissues of the dura mater and dura mater-fascia junction using bipolar electric welding. The methods of light microscopy and infrared spectroscopy were used. When evaluating the results, no β-structured aggregates were observed in the tissue samples under study. There was minimal traumatic damage to the adjacent dura mater tissue and minimal thermal damage from vaporisation. Pacchioni granulations, venous pial, and cortical vessels of the dura mater were preserved. The study observed complete identity of the wave values of amide A, B, amide I, II spectra; preservation of amide A, B peaks. Preservation and curvature of the N-H arm and O =C-N band were changed within acceptable limits. The findings indicate the absence of β-structured protein aggregates in the junction area, which excludes the possibility of fibrous structures and, as a result, does not contribute to the formation of a meningeal scar. The structure of the collagen protein in the junction area is normal, altered but intact, with preservation of its functions. This indicates the feasibility of using the method of high-frequency bipolar electric welding for surgical closure of defects of the dura mater, as an alternative to closure with suture material

The purpose of the research was to analyse modern scientific achievements in the field of autonomic functions in children with different types of syncope. The review used the full texts of English-language studies published between January 2018 and December 2022 and published in the PubMed Medline and Scopus databases. It has been established that the active orthostasis test, tilt test, circadian blood pressure rhythms and heart rate variability are the most commonly used functional autonomic tests in paediatric practice. They allow evaluating the spectrum of pathological cardiovascular reactions in a standing position; identifying types of orthostatic hypotension and causes of orthostatic intolerance; diagnosing orthostatic hypertension, postural orthostatic tachycardia syndrome, presyncope or syncope; to differentiating between sympathetic and parasympathetic autonomic dysfunctions and psychogenic transient syncope and epilepsy; to recommend orthostatic training as a method of treatment of syncope with an orthostatic mechanism of development. Despite this, there is no consensus on the definition of autonomic disorders and the methodology for conducting functional autonomic tests in children of different ages, considering their gender, body mass index and time of assessment during the day. Thus, functional autonomic tests are additional methods of physical and instrumental examination of the patient that allow effective assessment of the autonomic nervous system and possible mechanisms of syncope development, differentiation of transient loss of consciousness, stratification of future risks and optimisation of treatment and preventive tactics of the child's management based on an individual patient-centred approach

This research aims to determine predictions of yellowfin tuna catch production and conditions of catch production in 2021-2025 and the factors influencing yellowfin tuna catches. This research was conducted in September 2021 at the Bungus Marine Fisheries Harbor. The data taken is primary and secondary. The analysis used is Catch Production Projection Analysis and quadratic (Polynomial) Regression Analysis. The research results show that in catch projections, there is data on fish catch production for 2021-2025, where predictions for the next five years will fluctuate, or yellowfin tuna production will increase yearly. In the results of quadratic (polynomial) regression research, the factors that most influence the output of yellowfin tuna catches using quadratic regression are the number of fishing gear with a coefficient of determination or R2 value of 0.9934 and the number of fishermen with a coefficient of determination or R2 value of 0. 9934. The coefficient of determination or R2 value is 0.9599

This study was conducted in March 2023 in the coastal waters of the eastern part of the island of Rupat, Riau Province. The method used in this study used the purposive sampling method at 3 station points. Water samples were used to analyze nitrate and phosphate analyzed using Ultraviolet Spectrophotometry, and analysis of water organic matter using the titrimetric method. Diatom sampling using plankton net measuring 25 µm. The results of the study found 14 species from 3 classes of diatoms namely Bacillariophyceae, Cyanophyceae, and Conjugatophyceae. Diatom abundance ranged from 472.22 - 993.05 cells/L. The regression equation for nitrate on diatoms is Y= 929.151-3194.045x. The coefficient of determination (R2) of 0.080 indicates that the effect of nitrate on diatom abundance has a weak close relationship. The effect of phosphate on diatom abundance has a coefficient of determination (R2) of 0.105 and the effect of phosphate has weak proximity. The influence of water organic matter has a coefficient of determination (R2) of 0.033 with a very weak effect. The analysis shows that the concentration of nitrate (NO3) is included in the oligotrophic fertility level, namely the low fertility rate

The services of the Bungus Ocean Fishery Port, as the only tuna Fishery port in West Sumatra, support the availability of facilities required by each tuna industry stakeholder. The purpose of this study is to determine the services from the Bungus Ocean Fishery Port that fisheries stakeholders, especially tuna, are currently experiencing: and to determine the level of satisfaction of tuna entrepreneurs with the performance of the Bungus Ocean Fishery Port. The data analysis used is weighting or scoring, and then IPA and CSI analysis is carried out. The results showed that the Bungus Ocean Fishery Port played a good role in providing production activity, infrastructure and public services, and stakeholder’s tuna feel they are quite satisfied with the performance of the Bungus Ocean Fishery Port in supporting the tuna industry and several service attributes of the Bungus Ocean Fisheries port still need to be improved.
L’impact de la sinistralité passée sur la sinistralité future : approche empirique en assurance automobile
Authors: Vasechko Olga A. , Grun-Réhomme Michel
Published: November 2023

Le risque individuel de chaque assuré automobile n’est pas prévisible et n’est connu qu’a posteriori, à l’inverse du risque collectif qui est prévisible dans la mesure où l’on dispose de l’expérience du passé le plus récent observé sur une population assez grande comparable à celle du portefeuille actuel. Dans cet article, on souhaite examiner de façon empirique, si la sinistralité passée (avant l’année de référence) et la sinistralité actuelle constituent un bon indicateur prévisionnel de la sinistralité future, conditionnellement aux caractéristiques de la classe de risque (ou case tarifaire) de l’assuré. On suppose, en fonction de la sinistralité passée, que chaque classe de risques est constituée de deux catégories de conducteurs : les assurés à bas risques et ceux à hauts risques. À l’aide d’une loi binomiale négative et d’une approche bayésienne, on montre que la probabilité d’être un conducteur à bas risques est plus importante en l’absence de sinistres (ou avec un seul sinistre) et qu’à l’inverse la probabilité d’être un assuré à hauts risques augmente fortement dès que l’assuré a 2 ou 3 sinistres au cours de l’année de référence. Bien sûr le niveau de probabilité varie selon les classes de risque. Dans presque tous les cas, la sinistralité passée est un bon indicateur de la sinistralité future.
Importance of Digitalization for Sustainable Development of Maritime Industry

Published: November 2023

Maritime transport is the driving force of global trade and is one of the fundamental activities of the blue economy. In the face of changes in globalization, it must face technological change. According to the United Nations Conference on Trade and Development, the global commercial shipping fleet grew by 3 percent, in 2020 to 99,800 vessels of 100 gross tons or more.

One of the key drivers of technological change in the maritime industry is digitalization. The digitalization of shipping is a step toward making it more environmentally friendly and efficient. This will lead to significant cost savings and improve vessel efficiency, transparency and market access. For the future development of the maritime industry, digitalization combined with environmental sustainability is essential. Experts agree that the COVID -19 pandemic has created certain challenges but also opportunities by creating a great imbalance in the industry and accelerating the progress of digitalization and innovation. The fourth industrial revolution is expected to have a significant impact on maritime transport.

The IMO Convention on Facilitation of International Maritime Traffic and the WTO Agreement on Facilitation of International Maritime Traffic have created common standards and regulations that have paved the way for digitalization. Despite the technological advancements in the maritime industry, there is still much room for further research in developing countries.

Digitalization in the maritime sector should be promoted as part of global efforts to increase supply chain resilience. It is the pathway to greener and smarter shipping, and this paper aims to provide an insight into the digitalization of shipping and highlight its importance for the future, as well as demonstrate that it contributes to achieving the sustainable development goals. The level of digitalization in seaports and maritime transport will also be analyzed. The adoption of digitalization in the maritime industry is essential and will lead to greener maritime transport, a robust economy and increased safety.

The paper includes primary research on the example of shipowners in the coastal liner passenger transport of the Republic of Croatia, and a questionnaire consisting of 19 questions was used to conduct the research.
