Authors: Wang Peixu , Keat Ooi Boon , Talib Zunirah Mohd
Published: May 2024

As an extension of ecological concepts, urban green development has gradually become a new bridge for various countries or regions to achieve sustainable development. Based on the panel data of 17 cities in Henan Province, China from 2007 to 2022, this article uses the entropy method to measure the green development level of cities in Henan Province, and uses the Dagum Gini coefficient method to analyze the green development differences between cities. The results show that: first, urban green development in Henan Province is generally at a lower-middle level and tends to be balanced. Second, there are obvious regional gaps in urban green development in Henan Province. Third, inter-regional disparity is the main reason for the differential distribution of urban green development levels in Henan Province. In order to promote the improvement of urban green level and narrow the spatial development gap in Henan Province, this study puts forward corresponding policy suggestions from the aspects of green investment, green technology innovation, industrial structure upgrading and green life. This also provides reference for other less developed regions in China to achieve balanced urban green development.

The Intellectual Class and the Rise of German Cultural Nationalism
Authors: Chen Sifan
Published: May 2024

German cultural nationalism emerged in the context of the invasion of French culture. This cultural nationalism was different from the nationalism represented by Britain and France, which focused on the expression of nationalism from the cultural level, and made use of cultural connection and unity to achieve the establishment of a nation state. In the 17th and 18th centuries, French culture invaded Germany in all aspects, and the aristocrat and the middle classes of the German states were proud of speaking French, while German was neglected as a national language. Against the background of the political and economic unification of the German region, a group of Deutsch intellectuals began to actively propagate and promote the German culture and language, hoping to establish a unified German national identity from the cultural identity to complete the unification of the country, and to make the German state regain its historical glory. The subsequent historical development proved that German cultural nationalism became the foundation stone of German unification. After the Napoleonic Wars, German cultural nationalism was further transformed into German political democracy, and Prussia finally completed the unification. How did German cultural nationalism emerge from all this, and what was the role of the German intellectual class in it? By studying this period of history, this paper is able to further understand the intricate international context and international situation in Western Europe at that time. At the same time, it draws on the positive factors of German cultural development.

SOUVENIR AUSHADH 2K24 CONFERENCE PROCEEDINGS
Authors: T Babu Merlin , N. Madhavi
Published: May 2024

Intercellular junctions known as desmosomes facilitate cell-cell adhesion and secure the intermediate filament network to the plasma membrane, giving tissues like the heart and epidermismechanical robustness. Desmosomal proteins play essential roles in adhesion, but they are now becoming known as cell signalling mediators that are necessary for healthy cell and tissue functioning. The knowledge on desmosomal proteins controlling adhesion and signalling in healthy skin, including morphogenesis, differentiation and homeostasis, wound healing, and defence against environmental harm, is summarised in this study. We also talk about howpathogenesis is aided by human disorders that either directly or indirectly interfere with these mechanical and signalling functions of desmosome molecules. At least three distinct protein families are represented in desmosomes: armadillo proteins like plakoglobin (Pg) and plakophilin (Pkp2) isoforms, cadherin-type adhesion proteins that are members of the desmoglein (Dsg) and desmocollin (Dsc) subfamily, and the plakin family member desmoplakin (Dp). Lipid raft membrane domains closely control desmosome turnover, while post-translational changes of plaque proteins, such as Dp phosphorylation, which finetunes the cytoskeletal anchoring of desmosomes, control their construction and disintegration.

Published: May 2024

The conducted study entitled The Use of Generative AI in Learning and Its Influence on Students’ Academic Engagement in Noveleta Senior High School seeks to provide insights on the relationship between the use of generative AI in learning and students’ academic engagement. A sequential-explanatory mixed-method research design is applied in the study to supply in-depth enlightenment, discussion, and investigation of the evaluated and correlated variables. Eighty-seven (87) respondents served as participants for the quantitative phase of the study, and ten (10) interviewees for the qualitative phase. The respondents were selected using Convenience Sampling, a non-probability sampling technique. Findings showed that use of generative AI has positively affected students' academic engagement and it improved their learning environment. On the other hand, generative AI has been a great aid in enhancing students' learning and engagement. Using Pearson R- Correlation, the researcher found that there is a significant high positive correlation between use of generative AI and students' academic engagement (r (87) = .765, p < 0.00001), while it has a good effect on their academic engagement. Generative AI has also made students lazier and more reliant on it which bears a lot of risk especially in academics. The duality of generative AI has been evident to the respondents of the study.

Published: May 2024

This narrative inquiry dives into the resilience and strength of parents raising children with Trisomy 21. The metaphoric framework of building a house illustrates the progressive and complex experiences of parents with Trisomy 21 child. This study is based on eight purposively selected participants, initially grappling with shock and denial is akin to laying a foundation, followed by understanding genetic and societal implications as the house structure rises. Coping strategies and adapting to care needs represent building walls and installing a roof. Within this metaphorical house, evolving acceptance and support networks shape family dynamics and social interactions. The narrative not only captures personal growth and deeper family bonds but also reflects broader societal shifts toward inclusion. This metaphor for home building not only builds up a narrative inquiry but also highlights the progressive development of resilience and deeper family bonds, which is illustrated by significant personal growth and societal shifts towards inclusion.

Precarious Tightrope Between External Debt and Economic Growth: A Comparative Analysis of Bangladesh and Sri Lanka
Authors: Tajammal Ramshah , Butt Sadia
Published: May 2024

In recent years, the foreign debt in South Asian economies has risen to concerning levels, suggesting that these governments are unable to generate enough revenues to finance their budget, which could most likely increase the risks of a debt crisis. This study looks at the relationship between foreign debt and the economic growth of two South Asian countries—Sri Lanka and Bangladesh—using Autoregressive Distributed Lag (ARDL) models from the period of 1984 to 2022. The comparative results demonstrate a persistent detrimental impact of foreign debt on both countries' economic growth trajectories. Moreover, our research emphasizes the importance of the debt-to-ԌDP ratio, suggesting that a higher percentage of external debt increases the adverse impact on ԌDP growth. The study compares the external debt levels of both countries and its consequences on their economies. Both Bangladesh and Sri Lanka suffer negative consequences from external debt. However, the study indicates that Sri Lanka, burdened with heavier debt, experiences a more pronounced impact on its economic growth trend as compared to Bangladesh. The study aims to address the pressing issue of rising foreign debt in South Asian economies, provide empirical evidence of its impact on economic growth, and offer policy recommendations. The findings have implications for both Sri Lanka and Bangladesh, emphasizing the importance of managing debt effectively.

Published: May 2024

This study examined how cost-effective it was to raise three distinct kinds of ducks using three different types of feed. The results of this study should help researchers and the general public, particularly breeders, by supplying information on the kinds of feed and duck varieties that are more cost-effective in duck farming. Three distinct types of feed and three distinct breeds of ducks were used in this investigation. The study used an experimental design with a factorial pattern (3 x 3) and a completely randomized design (CRD), with three replications made up of two components with the codes factor A and factor B. A1 (feed BR1), A2 (feed PP3), and A3 (feed mix) make up factor A, which is the type of feed. Duck types comprise factor B, which includes B1 (Peking duck), B2 (Mojosari duck), and B3 (MA duck). The factors that were observed were feed cost per gain (FCG), economic efficiency of ration usage (EEPP), and efficient use of rations (FE). The acquired data were subjected to variance analysis (ANOVA), and the Duncan multiple range test (DMRT) was used to determine how the treatments differed. The study indicated that variables A and B did not interact in treatments. Regarding the cost-effectiveness of using feed, factor A had a highly significant effect (P > 0.01). However, factor B had no discernible impact. This study concludes that the PP3 type of ration, which uses the more efficient Peking duck, has the best cost-efficiency when using rations. Based on the study findings, the recommendation is to employ Peking ducks fed PP3 diets to raise broiler ducks to their maximum body weight while minimizing ration expenses.

Indonesia's growing population continues to increase the need for animal protein, including meat, milk, and eggs. Public awareness of the importance of animal protein in nutrition is increasing. In this context, meat becomes one of the most consumed sources of animal protein, because in addition to its good taste it is also due to its high nutritional content. Field Work Lectures (MPAs) are conducted to apply theory in field practice, especially in broiler chicken rearing management. MPA activities are carried out in the cages of partner breeders of PT. Pitik Digital Indonesia in West Java, which includes primary and secondary data collection and implementation of maintenance management standards. The productivity project results of the Farming program show increased efficiency in achieving the expected chicken weight, through improvements in facilities and infrastructure as well as the use of applications that facilitate maintenance. Broiler rearing management involves several stages, including cage preparation, feeding, maintenance, to the harvesting process. The cage used has a semi-closed system and faces from North to South.

Learning Islamic Education Online
Authors: Sopiah Sopiah
Published: May 2024

The COVID-19 pandemic has forced educational institutions around the world to shift to online learning. However, the impact of online learning on Islamic Religious Education (PAI) learning in secondary schools is still poorly understood. This study aims to evaluate the achievement of student competence in online PAI learning. This study used a qualitative approach with primary and secondary data from teachers, supervisors, and students in several secondary schools. The results showed that online PAI learning tends to be more oriented towards text comprehension, ignoring students' affective aspects, and eliminating social interaction in the learning process. Independent individual learning, lack of teacher-student interaction, and time restrictions also have an impact on neglecting the affective dimension of students. The implication of this finding is that online PAI learning has not been able to achieve overall learning objectives, especially in the development of students' cognitive, affective, and psychomotor competencies. It is necessary to adjust learning strategies so that online PAI learning can be more effective and meaningful for students in the future.

The creation of class schedules requires a high level of precision and focus to generate the best possible timetable. A schedule with the best solution can provide comfort for both faculty and students, thus enhancing the quality of early meetings during classes. However, in the engineering faculty of Muhammadiyah University Cirebon, classes often do not start simultaneously with other faculties due to the manual scheduling process. Addressing this issue, a system is needed to automate the creation of class schedules. By implementing the Constraint Satisfaction Problems method to impose constraints before evaluating the fitness values in the Genetic Algorithm, it can assist in searching for the best solutions in accordance with the scheduling requirements of each program in the Engineering faculty. The results of black box testing on the system, item code 06, demonstrate that the system can produce schedules that comply with the requirements of each program in the faculty.
Dekalog dalam Praktik Katekisasi sebagai pedoman bagi Generasi Z di era Digital
Authors: Manurung Virdo
Published: May 2024

Penelitian ini bertujuan untuk menegaskan ajaran Dekalog sebagai pedoman bagi generasi Z atau digital natives. Hal tersebut dirasa perlu untuk ditinjau secara khusus sebagai upaya gereja dalam membimbing, mendidik, serta mengajari setiap warga jemaat, terlebih jemaat yang dapat disebut sebagai masa depan yang akan mengambil alih keseluruhan instrumen pelayanan gereja. Dekalog yang dimaksud merujuk kepada sepuluh perintah Allah yang dapat ditemukan dalam Keluaran 20 dan Ulangan 5. Dalam kultur Israel, Dekalog merupakan hukum Allah bagi umat-Nya. Dekalog mencakup perintah-perintah yang terkategorikan dalam dua aspek besar, yakni hubungan kepada Allah dan juga sesama. Dekalog biasanya diajarkan gereja pada proses pemuridan dengan tujuan pendewasaan iman yang sering disebut sebagai katekisasi. Sejak kekristenan mula-mula, pengajaran tentang Dekalog tidak pernah ditinggalkan untuk diajarkan kepada para murid dan itulah yang senantiasa dipertahankan sampai pada era kedatangan para misionaris ke tanah nusantara, bahkan hingga kini. Sayangnya, pada masa kini, pengejawantahan Dekalog dalam proses katekisasi sudah hanya seperti materi formalitas saja, padahal generasi Z dinilai sangat rentan dihantam pengaruh buruk kemajuan digital yang pesat, tentunya ini menjadi tantangan yang harus dijawab melalui sumbangsih peran gereja. Untuk itulah, penelitian ini ditinjau penting, apalagi dalam proses menghadapi era digital.

SCIENTIFIC, POPULARISATION AND CIVIL ACTIVITY OF MYRON KORDUBA DURING THE GREAT WAR
Authors: YANYSHYN Bohdan
Published: May 2024

The purpose of the article is to clarify the peculiarities of public activity and the scientific work of M. Korduba during the First World War. The methodological basis of the work is an interdisciplinary approach. Particular emphasis is placed on the structural and functional system analysis of historiographical facts and the method of critical analysis of documentary material. The scientific novelty of the article consists in an attempt to comprehensively reconstruct the intellectual biography of M. Korduba during the Great War. Conclusion. In the end, it was noted that the reconstruction of M. Korduba's life and activities during the First World War portrays him as one of the leading representatives of the Ukrainian intelligentsia of the modern era of national revival. Not being a professional politician by his chosen lifestyle, the scientist lively responded to the numerous needs of the Ukrainian public deprived of its own statehood. During the Great War, he directed his energy to the most important areas of national progress: he carried out cultural and educational work among prisoners of war, wrote popular scientific texts necessary for the self-education of the general public, defended Ukrainian interests with a journalistic pen when discussing the model of the post-war world order, etc. But M. Korduba's range of public talents was most fully demonstrated by the events of the establishment of national statehood in the western Ukrainian lands after the collapse of the Austro-Hungarian Empire. It was his composure in difficult situations, responsible initiative and public courage that largely made it possible to declare a short-term, but important for the national self-awareness of the people of Bukovyna, political independence. The events of that time crystallized the sobornist convictions of Korduba-politician, as evidenced by the scholar's intellectual biography of the interwar period, in which once again scientific creativity and public service were inextricably intertwined.

During the Great War, Volyn became one of the arenas of confrontation between the troops of the Entente and the Triple Alliance. The First World War on the territory of Volyn was affected not only by the battles of Russian and Austro-Hungarian troops, but also by the active activities of a number of civic organizations, mainly of a charitable nature, who wanted to help military and civilian victims of the conflict. The aim of the research is to present the activities of general state and local charitable civic organizations in sub-Russian urban centers of the Volyn province in 1914–1916. Considering the scope and nature of the article, we bypass with our attention the analysis of the activities of ethnic public structures, the Russian Red Cross Society, as well as charitable organizations of associated with members of the Romanov dynasty. The research methodology is based on the use of general scientific and specially historical research methods, including problem-chronological, synchronous, diachronic, comparative-historical and others. The scientific novelty is that the author tried, on the basis of unpublished archival materials, to highlight the activities of general state and local civic charitable initiatives in the sub-Russian urban centers of the Volyn province in 1914–1916. Conclusions. It was established that during the Great War, the towns of Volyn were important centers of civic charitable practices. Not only the general state structural units of the All-Russian Union of Cities, but also local civic initiatives, such as the Lutsk Town Committee for Aid to War Victims or the Municipal Committee for Assistance to the Poor Residents of Kremenets, carried out charitable activities here. Some wealthy townspeople were also involved in charitable activities. In general, during the Great War in Volyn, as well as in other Ukrainian provinces of the Russian Empire, we can observe the phenomenon of public activism as a substitute for the ineffectiveness of state institutions and a compensator for the limitations of self-governing bodies in solving urgent social problems caused by the war.
INTERNATIONAL PROBLEMS ON THE PAGES OF «NASH LEMKO» («OUR LEMKO»): THE UKRAINIAN-RUSSIAN CONFRONTATION
Authors: NAKONECHNYI Volodymyr
Published: May 2024

The purpose of the article is to find out the peculiarities of the interpretation of the past and current state of Ukrainian-Russian relations by the authors of «Our Lemkо». The research methodology is based on the combination of principles (historicism and objectivity) and methods (philosophical, general scientific and special-historical) of scientific research, which are usual for works on the historical science. The scientific novelty of the article consists in an attempt to comprehensively reconstruct of the problems of Ukrainian-Russian relations, presented on the pages of the flagship Ruthenian periodical of the interwar period, the magazine «Nash Lemko». Conclusions. Summarizing the reconstruction of Ukrainian-Russian relations presented on the pages of «Nash Lemko», we will point out its conceptual thoughtfulness and content saturation. In the first case, the editors were concerned with the consistent affirmation of Sobornist thinking among their readers. Through this prism, Moscovia became the eternal enemy of Ukrainians, which destroyed its unity by all possible means with the aim of further physical subjugation and spiritual extermination. This worldview model was carefully substantiated by the magazine's publicists with numerous examples from the Middle Ages to modern times. They consistently proved to the reader the civilizational difference between European Ukrainians in terms of their values and the barbaric world of Russian despotism. Affirming the optimism of life among the Rusyns, who were impoverished by the troubles, the authors of «Our Lemkо» emphasized the historical invincibility of Ukrainians in this unequal and cruel struggle, based on the ethical principle of the teleological superiority of good over evil. Finally, let us point out the success of the national policy of the publishers of the Ruthenian periodical, because despite the powerful leveling influences and the lack of their own statehood, the Lemkоs mostly remained with the Ukrainian national choice.
THE CREATIVITY OF MYKHAILO MAKSYMOVYCH IN THE HISTORIOGRAPHIC RECEPTION OF MYKHAILO HRUSHEVSKY
Authors: BILA Svitlana , TELVAK Viktoria
Published: May 2024

The purpose of the article is the elucidation of the features of the historiographical discourse of Hrushevsky, who was the expert on M. Maksymovych’s studies. The methodological basis of the work is an interdisciplinary approach. At the same time, methods of philosophical, general-scientific and specific-historical character are applied as well. Particular emphasis is placed on the structural and functional system analysis of historiographical facts and the method of critical analysis of documentary material. The scientific novelty of the article consists of a special analysis of the historiographical studies of M. Hrushevsky, devoted to the intellectual biography of M. Maksymovych. Conclusions. Summarizing M. Hrushevsky’s reflection about M. Maksymovych, let’s first of all pay attention to its leading feature, which, in our opinion, is decisive for the spirit of the scientist’s entire historiographical legacy. This is the understanding of the priority of the interests of science, embodied in the well-known slogan of the most outstanding researcher – nemini credere, proclaimed by him at the dawn of his scientific career and consistently applied in practice. Thanks to such a critical attitude, the historiographical works of M. Hrushevsky, dedicated to his outstanding predecessor (“Maksymovich's "Little Russian Songs" and a century of Ukrainian scientific work”, “One hundred years of Ukrainian nationalism”, “Development of Ukrainian studies in the 19th century and their revelation of the main issues of Ukrainian studies”, etc.), fall back from the previous apologetic tradition in his perception and appear as attempts at intellectual biography, which inherent not so much admiration for the greatness of the researched figure, but an effort to show it in the context of the processes and events of the Ukrainian nineteenth century, to reveal and explain to the reader not only outstanding achievements but also often unfortunate miscalculations. This methodological approach of M. Hrushevsky turned out to be extremely fruitful and to a large extent explains the long-term popularity of his observations in regard to M. Maksymovych, which have not lost their influence even today.
Dialog Profetis
Authors: Siagian Joan Nami Pangondian , Nono Fredirikus
Published: May 2024

The focus of this study is prophetic dialogue of the church’s mission for domestic migrants in the Diocese of Tanjung Selor, North Kalimantan. The socalled prophetic dialogue is very relevant to be applied in the Diocese. The local church is an example of the multi-cultural face of the Church. The Diocese of Tanjung Selor has greatly been influenced by the presence of migrants who come in from the various tribes and cultures throughout the country. The theological method used in this study is that of Stephen B. Bevans’ theological endeavors. Based also on the theology of Second Vatican Council, such as the Decree of Ad Gentes and referring to the thoughts of today’s theologians, the article promotes the prophetic dialogue to be taken into consideration within the Diocese. This research will specifically discuss how the prophetic dialogue is applied to migrant workers.
Special homogeneous curves
Authors: Lindemann David
Published: May 2024

We classify all special homogeneous curves. A special homogeneous curve $\mathcal {H}$ consists of connected components of the hyperbolic points in the level set $\{h=1\}$ of a homogeneous polynomial $h$ in two real variables of degree at least three, and admits a transitive group action of a subgroup $G\subset \mathrm {GL}(2)$ on $\mathcal {H}$ that acts via linear coordinate change.
Two classes of $C^*$-power-norms based on Hilbert $C^*$-modules
Authors: Abedi Sajjad , Moslehian Mohammad Sal
Published: May 2024

Let $\mathfrak {A}$ be a $C^*$-algebra with the multiplier algebra $\mathcal {L}( \mathfrak {A})$. In this paper, we expand upon the concepts of “strongly type-$2$-multi-norm" introduced by Dales and “2-power-norm" introduced by Blasco, adapting them to the context of a left Hilbert $\mathfrak {A}$-module $\mathscr {E}$. We refer to these adapted notions as $\mathscr {P}_0(\mathscr {E})$ and $\mathscr {P}_2(\mathscr {E})$, respectively. Our objective is to establish key properties of these extended concepts.
We establish that a sequence of norms $(\lVert \cdot \rVert _k :k\in \mathbb {N})$ belongs to $\mathscr {P}_0(\mathscr {E})$ if and only if, for every operator $T$ in the matrix space $\mathbb {M}_{n\times m}(\mathcal {L}( \mathfrak {A}))$, the norm of $T$ as a mapping from $\ell ^2_m(\mathfrak {A} )$ to $\ell ^2_n(\mathfrak {A} )$ equals the norm of the corresponding mapping from $(\mathscr {E}^m,\lVert \cdot \rVert _m )$ to $(\mathscr {E}^n,\lVert \cdot \rVert _n )$. This characterization is a novel contribution that enriches the broader theory of power-norms. In addition, we prove the inclusion $\mathscr {P}_0(\mathscr {E})\subseteq \mathscr {P}_2(\mathscr {E})$. Furthermore, we demonstrate that for the case of $\mathfrak {A}$ itself, we have $\mathscr {P}_0(\mathfrak {A})=\mathscr {P}_2(\mathfrak {A})=\lbrace ( \lVert \cdot \rVert _{\ell ^2_k(\mathfrak {A} ) } :k\in \mathbb {N} )\rbrace $. This extension of Ramsden's result shows that the only type-$2$-multi-norm based on ℂ is $(\lVert \cdot \rVert _{\ell ^2_k } :k\in \mathbb {N} )$. To provide concrete insights into our findings, we present several examples in the paper.
Special folding of quivers and cluster algebras
Authors: Kaufman Dani
Published: May 2024

We give a precise definition of folded quivers and folded cluster algebras. We define a special folding of a quiver as one which cannot be associated with a skew-symmetrizable exchange matrix. We give many examples of including some with finite mutation structure that do not have analogues in the unfolded cases. We relate these examples to the finite mutation type quivers $X_6$ and $X_7$. We also construct a folded cluster algebra associated to punctured surfaces which allow for self-folded triangles. We give a simple construction of a folded cluster algebra for which the cluster complex is a generalized permutohedron.
Jordan norms for multilinear maps on $C^{\ast}$-algebras and Grothendieck's inequalities
Authors: Christensen Erik
Published: May 2024

There exists a generalization of the concept completely bounded norm, for multilinear maps on $C^{\ast }$-algebras. We will use the word Jordan norm, for this norm and denote it by $\lVert \cdot \rVert _J$. The Jordan norm $\lVert\Phi\rVert_J$ of a multilinear map is obtained via factorizations of $\Phi$ in the form $$\Phi (a_1, \dots , a_n) = T_0 \sigma _1(a_1)T_1 \cdots T_{(n-1)}\sigma _n(a_n)T_n ,$$ where the maps $\sigma _i$ are Jordan homomorphisms. We show that any bounded bilinear form on a pair of $C^{\ast }$-algebras is Jordan bounded and satisfies $\lVert B\rVert _J \leq 2\lVert B\rVert $.
