Authors: Kayar Mahmut , Ceviz Nuray
Published: December 2024

Social media has become an indispensable element of our lives with the development of technology and the increasing usage of smartphones. Individuals’ instant access to any information they want has removed all the limits to accessing information. All sectors are affected by this technological development positively or negatively, and companies have to use social media tools not only to sell products to customers who use products but also to watch, listen, reach, communicate, get to know and evaluate them. Therefore, these channels have created some new concepts thanks to their users and as a result, some new job descriptions have emerged. One of these is social media influencers. It is seen that these influencers inform their followers about the textile products they use, direct them, and sometimes even block them, causing sales to decrease. This development, which companies cannot remain indifferent to, causes some brands in the sector to make agreements with these influencers. Within the scope of this study, the positive and negative effects of social media influencers on the fashion industry will be examined, and the attitudes of companies in social media and the power of influencers in the industry will be discussed. The data regarding the phenomena mentioned in the study are limited to the phenomena in Türkiye.

Çok Kriterli Karar Verme Problemleri İçin Toplulaştırma Teknikleri
Authors: Orakçı Erhan
Published: December 2024

Çok kriterli karar verme teknikleri farklı alanlarda ortaya çıkan problemlerin çözümünde kullanılmaktadır. Karşılaşılan karar problemleri seçim, sıralama ve sınıflama olmak üzere üç grupta toplanmaktadır. Bu üç farklı yapıdaki problemlerin çözümünde yararlanılabilecek çok sayıda çok kriterli karar verme tekniği bulunmaktadır. Ancak, bu tekniklerle elde edilen sonuçlar birbirinden farklılaşabilmektedir. Bu noktada hangi teknik ile elde edilen sonucun en iyi sonuç olduğu belirsizdir. Bu nedenle problemin yapısına uygun farklı çok kriterli karar verme teknikleri ile çözümler elde edilmesi ve son aşamada bu çözümlerin toplulaştırılmasıyla nihai bir çözüme ulaşılması gittikçe artan bir yaklaşımdır. Farklı çok kriterli karar verme teknikleriyle elde edilen çözümlerin toplulaştırılmasında kullanılan teknikler toplulaştırma teknikleri olarak adlandırılmaktadır. Bu çalışmada, sıralamaların toplulaştırılması amacıyla Referans Alternatif Temelli Toplulaştırma Tekniği (RAT) geliştirilmiştir.
RAT’ın temel amacı, bir problem için kullanılan farklı çok kriterli karar verme teknik sonuçlarının toplulaştırılmasıdır. RAT; kullanım kolaylığı, ek bir teknik veya puanlamaya ihtiyaç duymaması ve tam sıralama problemini büyük oranda ortadan kaldırması bakımından diğer toplulaştırma tekniklerinden farklılaşmaktadır. Analizler sonucunda RAT’ın, diğer toplulaştırma teknikleri ile %99,93 oranında uyumlu sonuçlar verdiği görülmüştür. Bununla beraber RAT ile sonuçların ortalama %1,2’sinde tam sıralama elde edilemediği, karşılaştırılan diğer tekniklerde ise bu oranının en az %82 olduğu görülmüştür.
RAT 830.000 örnek üzerinden uygulanmış ve sonuçlar Borda, Copeland, Dodgson ve Kemeny toplulaştırma teknikleriyle karşılaştırılmıştır. Bununla beraber daha önce toplulaştırma tekniklerinin kullanıldığı 21 çalışma RAT ile tekrar çözümlenmiş ve sonuçlar karşılaştırılmıştır.
RAT’ın çok kriterli karar verme alanına önemli katkılar sağlayacağı, sosyal tercihler ve grup karar verme gibi alanlarda da başarılı bir şekilde uygulanabileceği düşünülmektedir.
SOVYET HAKİMİYETİNİN İLK YILLARINDA AZERBAYCAN BASININDA TÜRKİYE KONUSU (KOMMUNİST QAZETESİ KAYNAQLARINA BİR BAKIŞ)
Authors: Ahmadov Namiq
Published: December 2024

Sovyet dönemi Azerbaycan basınında Türkiye konusu ciddi merak uyandıran konulardan biri olmuştur. Bu makalede Sovyet hâkimiyetinin ilk yıllarında, dönemin basın organlarında yayınlanmış makale ve haberlerde Türkçülüğe karşı kıskanç tavırlar olmasına rağmen Türkiye ve Türkçülük hakkında yazıların çok ve detaylı olması örneklerle doğrulanıyor. Ayrıca “Komünist” gazetesinin alfabe reformu gerçekleştirilmesinde Doğu ülkelerinin ve Türkoloji Kurultaylarının bilgi ve propaganda işinin önemli bir araç olması gösteriliyor. İlimler Akademisi’nin, edebi-kültürel kurumların daha kurulmadığı yıllarda yayın evleri millî güçleri etrafında toplayan manevi merkez rolünde olmuştur.

Ama unutmamalıyız ki, gazeteler bağlı oldukları ana kurumların siyasetini yürütmek için yaratılmıştı ve onun maddi desteği ile basılıyordu. Bununla birlikte gazeteler millî düşünceyi unutmamış, makalelerin çoğunda millî bakış açısını korumaya çalışmış ve devamlı bunun cezasını çekmiştir.

“Komünist” gazetesinde 1920’lerde yayınlanmış makaleler Türkiye-Sovyet dostluğuna, Türkiye ile ilişkilerin geleceğine güven duygusu oluşturuyordu. Maalesef sonraları bunun Türkiye’yi komünist yapmak için Sovyet hükümetinin iç ve dış siyasetinin bir parçası olduğu belli oldu. Tabii ki, bu plan gerçekleşmediğinde baskılar başladı ve bu gazeteleri de es geçmedi. Yazarlar takip edilmeye başlandı. “Komünist” gazetesindeki “milliyetçilik yuvası”nı dağıtmak için defalarca girişimlerde bulunulduğuna dair belgeler var.

Authors: Teyin Görkem
Published: December 2024

İstanbul ilindeki restoran işletmelerinde kullanılan menü kartlarının mikrobiyal kontaminasyon yönünden değerlendirilmesinin amaçlandığı çalışma kapsamında amaçlı (kasti) örnekleme metodu kullanılarak İstanbul ilinin Kadıköy ilçesinde faaliyet gösteren 25 restoran işletmesindeki basılı menülerden steril kit kullanılarak örnekler alınmıştır. Örneklerde Escherichia coli ve Staphylococcus aureus bakterileri bakılmış olup, örnekler uygun sıcaklık ve sürede inkübasyona bırakılmıştır. Bu bakterilerin seçilmesindeki amaç kişisel hijyen ve insan kaynaklı bulaş hakkında indikatör olmalarıdır. İnkübasyon sonucunda numunelerin E. Coli ve S. aureus yönünden ortalama değerleri sırasıyla 0,84kob/10cm2 ve 0,99kob/10cm2 olarak tespit edilmiştir. Elde dilen bulgular incelendiğinde menü kartlarının mikrobiyal yükünün özellikle S. aureus yönünden yüksek olduğu, E. coli yükünün ise mevcut olup S. aureus kadar yüksek olmadığı görülmüştür. S. aureus insan orjinli, E. coli ise fekal kaynaklı bir mikroorganizma olduğundan akıllara gelebilecek temel nokta el ve kişisel hijyen konusudur. Menülerin her müşteri tarafından temas edilen bir araç olması özellikle mikrobiyal açıdan kontaminasyona ve hastalık bulaş riskine önemli zemin hazırlamaktadır. Konuyla ilgili kişisel hijyene ve el hijyenine önem verilmesi yadsınamaz bir gerekliliktir. Restoran işletmeleri fiziksel menüleri kimyasal dezenfektanlardan etkilenmeyecek materyaller ile kaplayıp periyodik olarak dezenfekte edebilir ya da dijital QR menülere yönelebilir. Alınacak bu gibi önlemler ile toplu gıda tüketim ortamlarındaki hijyenik koşulların sürdürülebilirliği sağlanmış olacaktır.

Published: December 2024

This study aims to contribute valuable insights into the experiences of parents raising children with intellectual disabilities, offering a holistic understanding of the complexities surrounding parenting stress and coping strategies. This qualitative research study explores the intricate dynamics of parenting stress and the coping strategies employed by parents in families raising children with intellectual or developmental disabilities, historically referred to as "mentally retarded children." The study employs a phenomenological research design, delving into the lived experiences of parents who navigate the unique challenges posed by their children's disabilities. Thematic analysis was employed to identify recurring themes and patterns within the interview transcripts. Multiple data sources, including interviews and participant observations, were triangulated to enhance the credibility and validity of the findings. The results of this study illuminate the diverse sources of parenting stress experienced by these families, ranging from emotional and behavioral challenges exhibited by the children to financial strain, societal stigma, and concerns about the future. Furthermore, the coping strategies employed by parents were found to be equally diverse, encompassing seeking social support, accessing professional assistance, practicing self-care, advocacy, problem-solving, fostering resilience, and more. These coping mechanisms were shown to significantly influence the physical and mental well-being of parents, their family relationships, work-life balance, and social connectedness.

Authors: Yao Ouyang , Jun Li , Xie Chi
Published: December 2024

As political boundaries, countries and cities as administrative boundaries may restrict the flow of goods and factors. Economic openness is to weaken the economic boundaries of countries and cities and promote the flow of goods and factors. As a super-large economy, China has actively promoted both opening-up to the outside world and domestic opening-up, integrating into the international economic circulation system and building a unified domestic market, creating a high-quality business environment for enterprises. The improvement of the environment has enhanced entrepreneurial performance and promoted technological innovation of small enterprises and urban economic prosperity. The research shows that there is an inherent and necessary connection between the degree of openness, business environment, and entrepreneurial performance. Economic openness and business environment promote the formation of a high-quality entrepreneurial environment, which in turn affects entrepreneurial performance and economic development performance. Namely, various changes in the business environment have greatly affected the "business dynamism".

Authors: Kaftandjiev Christo , Marković Dušan , Chou Linjie
Published: December 2024

Effective advertising of entrepreneurship is important for its quality and development. Semiotics (the science of sign systems) can help a lot in this respect. One of the main reasons for this is that every semiotic concept is also an efficient communicative approach or a communicative strategy. In this article, its author analyses advertising of entrepreneurship from the standpoints of four semiotic branches - alphabetics, semantics, syntactics and pragmatics. Visual metaphors are central part in these analyses - due to the fact, that the adpersons produce more than 90 percent of creative ads with their help. Ad appeals are the most important part of marketing pragmatics. The author thoroughly studies the eco appeals and the appeals for support (assistance), that are some of the most significant for entrepreneurial marketing communications. The article is important from the perspective of entrepreneurial advertising and provides valuable practical advice on how the adpersons can use semiotic concepts as effective communicative approaches and strategies.

Factors influencing total credit issuance to individuals: The role of economic indicators and cost of living
Authors: Karadjova Vera , Trajkov Aleksandar , Miloshoska Danijela
Published: December 2024

This study conducts a detailed regression analysis to explore the determinants of total credits extended to individuals in N. Macedonia over the period from December 2010 to May 2024. The dependent variable, total credits, is analyzed in relation to several independent economic indicators: the minimum union basket, COICOP-based inflation, COICOP cost of living indexes, and weighted interest rates on deposits and loans. The minimum union basket is examined for its influence on credit demand by reflecting the basic living standards required for wage negotiations. COICOP-based inflation provides insights into how price level changes affect the purchasing power and subsequently the demand for credit. Cost of living indexes, classified by COICOP, are analyzed to determine their effect on the real cost of living and credit utilization across various segments of the population. Weighted interest rates on deposits and loans are assessed for their impact on borrowing behavior and overall credit availability. This comprehensive analysis provides valuable insights into the interactions among these variables and their collective impact on credit dynamics, offering essential information for policymakers and financial institutions in developing effective economic and financial strategies. Understanding these relationships is crucial for policymakers and financial institutions to anticipate and mitigate economic fluctuations. Insights gained from this study can inform effective monetary and fiscal policies, enhance financial stability, and improve credit market responsiveness, ultimately supporting sustainable economic growth and individual financial well-being.
Socioeconomic status, ethnic gaps and discriminatory behaviour in the labour market: The European regions heterogeneity
Authors: Nese Annamaria , Mohsen Brahmi
Published: December 2024

This work examines any ethnic gaps between self-identified ethnic minorities and the majority of the population across Western European regions, taking into consideration the variations within native population and ethnic minorities due to family background (i.e., parents' education and occupation). The analysis shows that self-identified ethnic minorities and national majorities have significantly different socioeconomic levels; the observed ethnic gaps cannot be fully explained by individual educational attainment, family history, or challenges related to migration. Estimates of multilevel models have been made, with the individual outcome in terms of socioeconomic position and education as the dependent variable. Micro data from the European Social Survey are used in this investigation. The findings show that overestimating any ethnic gaps may result from ignoring social origins: parents with high socioeconomic status may better target their children in their decision-making, which may imply further disadvantages for ethnic minorities, particularly for the offspring of migrants who typically have low social origins. The findings also highlight how little intergenerational mobility there is in Europe.
Digital revolution and challenges for European legislation
Authors: Gongeta Sanja
Published: December 2024

The paper delves into the profound impact of the digital revolution on the European Union's legislative framework, with particular attention to the Digital Directives Package. It examines how the rapid acceleration of digital market dynamics necessitated the introduction of the Directive (EU) 2019/770, which addresses contracts for the supply of digital content and services, and Directive (EU) 2019/771, which governs contracts for the sale of goods. The analysis highlights the significance of these directives in enhancing the functionality of the Digital Single Market, promoting innovation, and ensuring robust consumer protection across EU member states. The paper underscores the EU's proactive stance in adapting its legal structures to meet the challenges of the digital era, ensuring that the regulatory environment keeps pace with technological advancements. By harmonizing rules across the single market, these directives not only foster cross-border trade but also safeguard consumer rights, laying the groundwork for a more integrated and competitive digital economy.

Published: December 2024

Recently, the application o f multi-criteria decision-making methods in the evaluation and selection o f trade performance has been very challenging. Because in this way more precise evaluations o f trade performance are obtained compared to the classic methodology. Bearing that in mind, this study comparatively analyzes the trade performance positioning o f the countries o f the European Union and Serbia using the DIBR and CODAS methods. The obtained empirical results indicate that German trade is in first place. The other top five countries include France, Italy, Poland, and Spain. So, the leading countries o f the European Union in terms o f trade performance are at the very top. Trade Croatia is in the twenty-seventh place. In twenty-eighth place is the trade o f Slovenia. Trade Croatia is better positioned than trade Slovenia. As ^ far as the trade o f Serbia is concerned, it is positioned in the twenty-sixth place. It is in a better position than the trade between Croatia and Slovenia. It is in a very bad position about the trade o f the leading countries o f the European Union. To improve the performance positioning o f Serbian trade, it is necessary to take relevant measures. The target performance positioning o f the trade o f the countries o f the European Union and Serbia can be achieved, among other things, by managing the number and size o f companies as effectively as possible, human resources, added value, employee costs, profit, sales, and increasing labor productivity. To that end, effective control o f other relevant factors is necessary.
Globalization of economic flows, the concept of the supply chain and the concept of the corporation
Authors: Cvetković Miodrag
Published: December 2024

The concept of the supply chain and the concept of the corporation exist in parallel today. The supply chain concept, unlike the corporate concept, is the concept of networking and/or integrating activities and processes from the most distant suppliers to end users in order to effectively deliver value to end users, which is the result of strategic thinking. The supply chain concept is based on the horizontal organization and integration of activities and processes with external partners, on the sharing of information, on a win-win strategy; the concept of the corporation is based on a vertical hierarchical organization within the corporation, on the "financialization" of all its operations and the creation of profits in commercial transactions with the environment and partners to be defeated. In globalized business conditions, these characteristics of both concepts become even more pronounced. Outsourcing and offshoring are business initiatives that are characteristic of both, the supply chain and corporations, and that can connect these two concepts, where the basic motives are different - value creation in one, or profit maximization in the other concept.
The characteristics of the landscape of the Vrbanja river basin in function of sustainable tourism development: Review of the special nature reserve ''Cvrcka''
Authors: Mišlicki-Tomić Tanja , Rajčević Vesna
Published: December 2024

The special nature reserve of the canyon of the "Cvrcka" river represents a significant river area on the northeastern slopes of the Čemernica mountain. It is located in the northwestern part of the Republic of Srpska, i.e., in the northern part of Bosnia and Herzegovina. This river system, with numerous waterfalls, cascades, and steep cliff s, was formed by the erosive action of the Vrbanja and Cvrcka rivers. The bed of the Vrbanja river and its left tributary Cvrcka constitute the primary hydrographic resource of this special nature reserve. In the Cvrcka valley, specific plant and animal species (eagles and birds) inhabit, forming a unique biodiversity in this area. The Cvrcka river valley is attractive to visitors, with picturesque natural landscapes and authentic traditional objects. The study aims to determine whether the special nature reserve of the Cvrcka canyon represents an important resource for the development of sustainable tourism in the Republic of Srpska. The research methodology is based on structured interviews designed to measure elements of tourist attractiveness and mobility concerning the Cvrcka canyon. The obtained results from the conducted questionnaire will be used for analyzing the impact of tourism development factors and their interrelationships, which align with the Tourism Development Strategy of the Republic of Srpska. The obtained research results confirm the initial hypothesis about the importance of the Cvrcka canyon for the development of ecotourism at the level of the Republic of Srpska and Bosnia and Herzegovina. The paper also highlights the discrepancy between the significance of this area and the current state of its valorization and promotion. Finally, measures for the protection and valorization of the landscape values of the valley and the sources of the Cvrcka river are proposed. In this regard, better cooperation with relevant institutions is recommended, which will significantly contribute to the improvement of sustainable tourism and the development of the local area.

Understanding the factors that influence the competitiveness of a tourist destination is crucial for decision-makers, tourism industry, and academia. In previous research, the evaluation of a country's tourism competitiveness involved analyzing various dimensions, including natural and cultural resources, infrastructure, marketing, management, and the political framework, mainly from the perspectives of experts and industry. Studies focusing on the perception of foreign tour operators regarding the competitiveness of a destination are scarce. Given that they act as a link between the destination and foreign visitors, their perspective on the circumstances in the destination they sell is crucial. Therefore, the goal of this research is to evaluate the competitiveness of Serbia as a tourist destination from the perspective of foreign tour operators who include or plan to include Serbia in their offerings, identifying the strengths and weaknesses in Serbia's tourism. Based on literature review and discussions with selected tourism experts, a questionnaire with 61 items and five factors of Serbia's competitiveness model as a tourist destination was created. The research was conducted in March 2023 during ITB Berlin. A total of 58 foreign tour operators were surveyed. The results showed that foreign tour operators gave the highest ratings to natural and cultural resources, followed by the quality of nightlife and entertainment, local food, and restaurant offerings, indicating these aspects as key advantages of Serbia as a tourist destination. The hospitality of the local population, a pleasant atmosphere at the destination, and the attractiveness of Serbia as a tourist destination were also highly rated by tour operators. However, foreign tour operators also pointed out certain shortcomings in Serbia's tourism, especially in segments such as infrastructure, hygiene, political stability, marketing, visitor experience, and environmental sustainability, providing a clear picture of areas that require improvement for Serbia to better position itself in the international tourism market.

Authors: Anđelković Željko , Miljković Jovana
Published: December 2024

Geoheritage represents a significant potential in the tourism product of Serbia. Although essential, it is often absent enough in the tourist offer, and specialized tourist guides do not exist. Interpretation represents a specific form of mediation in the education of visitors, which is why the role of tourist guides is vital. Interpretation is a form of communication designed to interpret natural and cultural heritage through the direct encounter of visitors with artifacts and heritage. The tourist guide is the intermediary, and tourists' satisfaction often depends on their knowledge and skills. The aim of this paper is to present the role and importance of the personal interpretation of tourist guides as the main actors of geotourist education, as well as their role in creating visitor satisfaction in this specific area. Does and how much does geomythology help? What kind of storytelling is necessary for different visitor structures? What is the common denominator for all visitors to geoheritage sites - is it just pleasure or knowledge. If interpretation is also defined as a way of presenting certain artifacts with the aim of attracting visitors' attention and providing new knowledge, then tourist guides at geoheritage sites have an important role.

"Golubac fortress" is a unique and indivisible spatially functional entity, with natural and created resources and values of importance for tourism. As a cultural asset of exceptional importance, it belongs to the "Golubac fortress" Nature Reserve and the "Đerdap" National Park. In 2011 the Republic of Serbia declared "Golubac Fortress" Tourist Area, which is managed by the company with limited liability for the development of tourism "Golubac Fortress". The Tourist Area, which belongs to the territory of the Municipality of Golubac, is about 22 hectares. The main tourist attraction of the Tourist Area is an immovable cultural asset - the medieval fortress "Golubac fortress", which was restored through the project "Reconstruction of Golubac Fortress", fi nanced from IPA funds and offi cially opened for visitors in 2019. The aim of the paper is to point out the importance of managing attractions, with a special emphasis on medieval fortresses as complex products in tourism. "Golubac Fortress" is an example of good practice, how, through the application of the tourist attraction management model, it has turned from a neglected cultural-historical asset into an attractive tourist destination within the European cultural route "Fortresses on the Danube".

The interaction between cultural heritage and tourism is characterized by a long continuity and increasing intensity of mutual relations. This relationship and dynamics have been well studied and confirmed both theoretically and practically. However, the fact that is less recognized, researched, and respected, particularly in the case of foreign tourism, is considerable potential for enhancing complex relations in international cooperation. Serbia has long been recognized as a mosaic of spiritual and material culture from various epochs, with characteristics and influences from its immediate and wider surroundings (ethnic, religious, ideological, political). This paper focuses on Russian (Soviet) cultural heritage in Serbia. With all its spatial, temporal, and thematic differentiations, it significantly contributes to the overall cultural heritage. The most significant frequency, diversity, recognizability, and spatial presence were "imprinted" during the first half of the 20th century, but with varying intensity, it can be traced back almost a thousand years to the present day. This segment of cultural heritage represents significant potential for improving bilateral, as well as overall regional and international relations - tourism development, cultural exchange, economic, and political perspectives. This topic certainly has growing importance in the context of the current geopolitical situation. Russians are rediscovering Serbia as a desirable destination for tourism, spirituality, economy, and in every other context for both short and long stays.
Touristic valorization of Valjevo cultural potential
Authors: Novović Maja
Published: December 2024

Valorizing the cultural potential of the Valjevo region is vital for tourism development for several reasons. Cultural heritage sites, including monasteries, churches, ethno-villages, and traditional events, represent a rich heritage and serve as a valuable tourist resource. Preserving and promoting these elements not only attracts tourists but also provides them with an authentic experience. Cultural tourism significantly contributes to the local economy through various activities such as tourism, souvenir trade, hospitality, and accommodation. Furthermore, the promotion of cultural heritage encourages the preservation of tradition and community identity. This paper demonstrates how cultural potentials influence the development of tourism and the economy of the Valjevo region. The results are based on a combination of different research methods on cultural resources in the region, which provide a foundation for their valorization. The approach involved engaging the local population and potential visitors through questionnaires, qualitative-quantitative methods, and Hilary du Cros' methods for cultural potential valorization. By implementing smart planning and management strategies, Valjevo's cultural potential can form the basis for developing various forms of tourism, including cultural, rural, religious, and gastronomic tourism. Investing in restoring and promoting cultural monuments and events helps diversify tourism offerings, attracting visitors from different backgrounds. Therefore, valorizing the cultural potential of the Valjevo region is not just an investment in tourism but also a means of preserving identity, fostering economic development, and promoting local culture.

Authors: Miletić Milan
Published: December 2024

The study includes an analysis of vegetation cover in the period from 2000 to 2023 in the Sokobanjska Moravica basin. The vegetation analysis was carried out using the Normalized difference vegetation index (NDVI). The application of this method is reflected in the detection of areas where forest vegetation has been degraded, in the detection of illegal deforestation and in the determination of changes in land cover. The aim of the work is to detect changes in vegetation cover in the catchment area. The NDVI results were obtained by processing Landsat 5 and Landsat 8 satellite scenes in the QGIS software. The first scene was recorded on July 5, 2000 (Landsat 5), the second on July 21, 2023 (Landsat 8). When analysing the satellite scenes, the types of vegetation cover were identified on the basis of the NDVI values. The maps show the value of the index in 2000 and 2023 to make it easier to follow the text and visually observe the changes in the basin area. In the same way, maps vegetation types were created for the same study period. It was found that the vegetation cover underwent certain changes during the studied period. It was observed that the vegetation cover underwent certain changes during the period studied. The greatest changes were observed in the Sokobanjska, Aleksinacka and Dugopoljska basins, on the edge of all basins and on the slopes of the Rtanj. The smallest changes were observed in the higher parts of the basin, i.e. on the slopes of Ozren, Devica, Bukovik and Slemen. The area of forest vegetation has increased by 87% compared to the period since 2000. The area with mixed forests has increased the most in percentage terms compared to other land cover types. In contrast, the areas with scrub vegetation have decreased drastically.

Published: December 2024

Real-time systems are extensively used in many applications, especially critical systems. A real-time system is considered to be reliable and safe if it is able to execute all its tasks accurately within given time constraints. A requirement might need the real-time systems to execute several tasks. The system must be able to assign processors and necessary resources to ensure smooth and timely execution. In this paper, we give an overview of existing scheduling algorithms for static and dynamic systems. This paper also presents a comparative study of these scheduling algorithms.

Published: December 2024

The presence of the zoning system in the education system in Indonesia as a provision for determining the location of new students affects the mobility patterns of school-age children in Siak Hulu District.  The level of education is one of the indicators in measuring the Human Development Index in an area. However, the level of education must be balanced with the number of educational facilities that accommodate efforts to improve human quality. This sub-district, which has 12 villages with a total area of 98,707 hectares, has only 3 high school facilities, while when reviewed in SNI No. 3/1733/2004 the service coverage of high schools is only 3000 square meters with a population of 4,800 people. In addition, the zoning system that has been regulated does not include 3 villages in the zoning of Senior High School facilities in Siak Hulu District. This research seeks to provide recommendations for unserved areas linked to the zoning regulations in Siak Hulu Sub-district. The method used in this analysis is spatial data analysis with the weighting method and compared through weighted overlay. The results of the analysis show that there are three villages that are optimal locations for the construction of new high schools, namely Kepau Jaya Village, Tanjung Balam Village and Pangkalan Serik Village.
