We utilized a mixed equilibrium formulation with appropriate functions and a fixed-point principle for history-dependent operators to prove the existence and uniqueness of solutions. As an application to demonstrate the peculiar weak solution for a viscoelastic frictional contact problem that involves the unilateral signorini type condition for the normal velocity together with non-monotone normal damped response conditions and the Coulomb law of dry friction that friction bounds depend on the amount of accumulated slip.

However, students from rural areas often encounter signifcant challenges in their engineering studies and extracurricular activities, leading to higher dropout rates compared to their urban counterparts. To address this issue, we have developed a mathematical model that utilises fuzzy numbers and Newton's method to strategically prioritize core engineering activities. Tis model is designed to account for the unpredictability of student performance and aims to bridge the educational gap between urban and rural students. By focusing on essential activities, our approach seeks to enhance academic outcomes and increase success rates for engineering students across diverse educational settings. Tis innovative method provides a novel solution to the persistent educational disparities, ofering a pathway to more equitable and efective engineering education for all students.

We provide detailed characterizations of these ideals, focusing on their distinct properties and interactions within b-semirings. Utilizing an algebraic approach, we elucidate the fundamental properties of m-bi-ideals, examining their behavior and structural role. Additionally, we explore the generators of m-bi-ideals and offer characterizations based on their relationship with bi-ideals. Our findings contribute to a deeper understanding of m-ideals and m-bi-ideals, opening new avenues for further research in algebraic theory and the study of semirings.

The system does not possess monotonicity properties and the feasible set is unbounded in general. To solve the problem, we propose a completely implementable iterative scheme, whose convergence is proved under certain coercivity type conditions.

This study examines several formulas of imperative clause rules in previous research, which distinguished the use of gi and ga in positive imperative clauses, and neka and asi markers in negative imperative clauses. An intense interview was conducted with native speakers of the Kempo dialect and compared other examples used in previous studies to build a thorough conclusion. Some critical findings in this research are, firstly, the particles gi and ga are not an enclitic attached to the word they follow; secondly, the particles gi and ga are not specific markers for imperative clauses because they can also appear in other clause forms (e.g., declarative clauses); and thirdly, the words neka and asi in the negative imperative clauses of the Manggarai language can be used interchangeably and do not change the meaning. Thus, this study proves that there are no unique markers in the imperative clauses of the Manggarai language because the form varies relatively depending on the context with whom one is talking.

On the other hand, national government initiative of more centralistic management regime and omitting the role of long existing traditional institutions had not been successful in sustaining the resources. Therefore, this research aims at finding a more adaptive and accommodative community-based maritime resource management, through qualitative approach by description 1) the dynamic of coastal management's implementation on coastal community, 2) the execution of basic principal of coastal management-based on community, on program, and on combinations of community-based and program-based; and 3) key factors in contributing the existence of community-based and program-based coastal management. Result show that coastal community-based management is constructed and development through continuing socio-cultural changes over time. On the other hand, the dynamic of coastal program-based management is more on the level of community's need and sustainability of the ecosystem. Result also show that the execution of basic principal on coastal management by community is more dynamic and set up locality. The key factors influencing the existence of coastal management are based on the level of community's authority, as well as level of community's participation in management process. Based on the finding, this research recommended an adaptive and accommodative coastal resource management by acknowledging the coastal community capacity supported by the access and control of the government.

This study aims to: find out the competence of extension workers in the use of information and communication technology in Kendari City. This research was conducted to all agricultural extension workers with status as civil servants and honorary workers in Kendari City. This research was conducted from May to July 2022 which is a quantitative study. Where the results of the study were analyzed using class intervals. The results showed that the competence of extension workers in the use of information and communication technology was in the high category, which was seen from the perceptions of extension workers in using computers, frequency of computer use, computer operation, outreach activities using computers, advantages of computers in extension activities, support for effective computer use, application software and the internet.
