Abstract
One of the key issues faced by financial institutions in regards to their clients, is the problem of loan defaults by their clients, and this greatly affects the sustainability of various financial institutions in PNG. This paper investigates the causes, consequences, and potential solutions to this problem. The study aims to identify the factors that cause the development of such a problem and contribute to it growing. Some of the most common factors involved include age, income, employment status, past repayment records, the reason for taking the loan, the amount borrowed, the terms of the loan agreement, the interest rate on the loan, and the level of education of the borrower. This paper addresses problems that arise as a result of high loan default rates in terms of losses for financial institutions and other lending organizations, lack of access to credit for low-income earners, and issues that are related to financial stability. The methodology implements logistic regression, random forest, and XGBoost models, which are all coded and simulated using RStudio. The research paper suggests practical solutions which include better screening of borrowers through predictive models, better credit monitoring, and financial literacy programs. In PNG, there is a need for all stakeholders involved to come up with a solution that addresses this issue. Other key areas discussed in this paper include credit risk management, which involves data analytics that aim to reduce the chances of loan defaults and improve portfolio performance, ensuring that financial services are available to all our people.

Abstract
Chamaecyparis Genus As a group of cypress with great economic and ecological value, the taxonomic status and evolutionary history of Spach. have always been the focus of research in plant geography and phylogenetics. This genus was first formally described and named by the French botanist Édouard Spach in his book Histoire Naturelle des Végétaux in 1841 [1, 2]. The genus name ” Chamaecyparis” comes from the Greek words “chamai” (χαμαί, meaning “on the ground” or “short”) and “kuparissos” (κυπάρισσος, meaning ” cypress”), which largely reflects the initial impressions of some shrub-like horticultural varieties or juvenile forms of early observers. However, in natural primary forests, Cypress species are usually giant trees that can grow to 20 to 70 meters tall [3, 4, 5].

Abstract
This paper mainly presents the economic and technical limitations of Compressed Natural Gas (CNG) transportation by ship, particularly the low ratio of gas mass to container weight and the inefficiencies in loading and unloading processes that impact the overall project feasibility. The system validated that CNG loading requires 35–51 hours and unloading 46–55 hours, depending on seasonal hold temperatures. The key objectives were to develop a simulation model to accurately assess process durations, determine the total mass of transported gas, and also calculate the power and energy requirements for high-pressure systems under various operating strategies, including a comparative analysis between methane and hydrogen.
With the development of a MATLAB-based process simulation model designed specifically on the GASVESSEL project, this greatly utilizes the Type III composite vessels.

Abstract
The article examines the political and legal views of the great 13th-century Azerbaijani thinker Nasir al-Din Tusi. It analyzes Tusi’s ideas concerning the origin of the state, principles of governance, the concept of justice, legality, the duties of the ruler, the social structure of society, and issues of foreign policy. It has been determined that Tusi regarded the state as a political union formed as a result of the mutual needs of human beings, while justice was considered the principal foundation of the state. He maintained that the ideal ruler should be wise, educated, and just, and identified the welfare of the people as the primary objective of state policy. Tusi also emphasized that war should serve only as a last resort, advocating instead the superiority of peace and diplomatic relations. The article concludes that the political and legal ideas of the author are consonant with the principles of modern statehood and international law.
