Considering the growth of blockchain technology, the research aims to transform the efficiency of recommending optimal coffee suppliers within the complex supply chain network. This transformation relies on the extraction of vital transactional data and insights from stakeholders, facilitated by the dynamic interaction between the application interface (e.g., Rest API) and the blockchain network. These extracted data are then subjected to advanced data processing techniques and harnessed through machine learning methodologies to establish a robust recommendation system. This innovative approach seeks to empower users with informed decision-making abilities, thereby enhancing operational efficiency in identifying the most suitable coffee supplier for each customer. Furthermore, the research employs data visualization techniques to illustrate intricate clustering patterns generated by the K-Means algorithm, providing a visual dimension to the study's evaluation.

In the ever-changing landscape of finance, the fusion of artificial intelligence (AI)and pair trading strategies has captured the interest of investors and institutions alike. In the context of supervised machine learning, crafting precise and accurate labels is crucial, as it remains a top priority to empower AI models to surpass traditional pair trading methods. However, prevailing labeling techniques in the financial sector predominantly concentrate on individual assets, posing a challenge in aligning with pair trading strategies. To address this issue, we propose an inventive approach that melds the Triple Barrier Labeling technique with pair trading, optimizing the resultant labels through genetic algorithms. Rigorous backtesting on cryptocurrency datasets illustrates that our proposed labeling method excels over traditional pair trading methods and corresponding buy-and-hold strategies in both profitability and risk control. This pioneering method offers a novel perspective on trading strategies and risk management within the financial domain, laying a robust groundwork for further enhancing the precision and reliability of pair trading strategies utilizing AI models.

The purpose of this study is to implement game content within the generative artificial intelligence module Chat-GPTs, grounded in the humanistic discourse of self-reflection. This content aims to empower the dignity of the silver generation, which has been marginalized by digital technology. Simultaneously, we intend to prototype a digital psychotherapeutic tool. The development of a flexible device that adapts to the silver generation's living environment and temporal constraints is also part of our plan. However, there are still few commercially available products, and digital therapeutics developed in the form of content are virtually nonexistent. The goal is to implement game content that allows the elderly, who have been marginalized by digital technology, to find their true dignity. Simultaneously, we plan to commercialize a prototype of digital psychotherapy that can flexibly adapt to the range of living environments and time constraints of the elderly. This study has been extended based on the game content 'Daily Run' created by Hyein Kwon, an undergraduate student at Kyungil University.

Sustainability science is an emerging transdisciplinary research which necessitates not only the communication and collaboration of scientists, practitioners and stakeholders from different disciplines and interests, but also the paradigm shift from deterministic and reductionist approaches to the old basic. Ecological-societal systems (ESS) are co-evolving complex systems having many interacting parts (or agents) whose random interactions at local scale give rise to spontaneous emerging order at global scale (i.e., self-organization). Here, the flows of energy, matter and information between the systems and their surroundings play a key role. We introduce a conceptual framework for such continually morphing dynamical systems, i.e. self-organizing hierarchical open systems (SOHOs). To understand the structure and functionality of SOHOs, we revisit the two fundamental laws of physics. Re-interpretation of these principles helps understand the destiny and better path toward sustainability, and how to reconcile ecosystem integrity with societal vision and value. We then integrate the so-called visioneering (V) framework with that of SOHOs as feedback/feedforward loops so that 'a nudged self-organization' may guide systems' agents to work together toward sustainable ESS. Finally, example is given with newly endorsed Sustainable Development Goals (SDG) Lab (i.e., 'Rural systems visioneering') by Future Earth, which is now underway in rural villages in Tanzania.

Education is one of the priority sectors specified in Tanzania, and it has committed to provide 11 years of compulsory free basic education for all from pre-primary to lower secondary level. Despite the Government's efforts to provide free basic education to all children, there are 2.0 million (23.2 per cent) out of 8.5 million children at the primary school age of 7-13, who are out of school in Tanzania. The ICT class should be offered as a regular class in all secondary schools in Tanzania, recommended by the ministry of education. However, many schools are struggling to implement this mandate. Most of schools offer the ICT class with theory without any real hardware. Some schools were given with computers but they were not maintained for operation. There is a huge task to make ICT education universal. Main issues include: remoteness (off-grid area), lack of ICT teachers, lack of resources such as hardware, infrastructure, and lack of practical lessons or projects to be used at schools. An innovative blended ICT/STEM education program is being conducted not only for Tanzanian public and private/international schools, but also for out-of-school adolescents through institutions, NGO centers, home visits and at the E3 Empower academy center. For effective STEM education to take place and remain sustainable, more practical curriculum, and close-up teacher support need to be accompanied concurrently. Practical, project-based simple coding lessons have been developed and employed that students experience true learning. The effectiveness of the curriculum has been demonstrated in various project centers, and it showed that students are showing new interests in exploring new discovery, even though this was a totally new area for them. It has been designed for an easy replication, thus students who learned can repeat the lessons themselves to other students. The ultimate purpose of this project is to have IT education offered as universally as possible throughout the whole Tanzania. Quality education for all children is a key for better future for all. Previously it was hoped that education with discipline will improve the active learning. But now more than ever, we believe that children have the ability to learn on their own with given proper STEM education tools, guidelines and environment. This gives promising hope to all of us, including those in the developing countries.

In an attempt to illuminate the lives of elderly women, this article has studied the economical situation and economical well-being felt by the elderly women dwelling in the southwestern coastal islands of Korea. In this article, we have attempted to conduct a consolidated research that incorporates both qualitative as well as quantitative research methods. The researched areas included 6 islands. Here are the main results. : 1) The elderly women living in the islands were enduring various forms of excessive labor, and there were many cases where these women didn't receive adequate amount of compensation. There should be more considerations made by the locals and proper restrictions should be brought out in order to prevent these women from conducting excessive and hazardous tasks. 2) Due to unpropitious economical situations, the majority of the elderly women living in these islands were incapable of saving money. There should be a plan devised to empower the economical capabilities of these elderly women that will elicit economical effects. 3) The degree of economical well-being that these elderly women felt was very low, both in the absolute level of economical satisfactions, as well as the relative level of economical satisfactions compared to the people living in the cities. There should be an incorporated effort conducted by the elderly women themselves, the local society, and the relevant offices to increase the level of economical well-being that are felt by these elderly women.

Purpose: The purpose of this study was to explore the recovering process of men who had abused alcohol and has lived in a therapeutic community. Methods: Individual in-depth interviews were used to collect data from 10 of these men who has lived in the therapeutic community for more than one year. Qualitative data from field notes and transcribed notes were analyzed using the grounded theory methodology developed by Strauss and Corbin. Results: The core category about the recovering process of the men who had abused alcohol and are now in the therapeutic community was identified as "reconstructing a broken life". The recovering process of these men in the therapeutic community consisted of four phases; 'self-awareness stage', 'unfreezing stage', 'readjustment stage', and 'challenging stage'. Conclusion: In this study "reconstructing a broken life", as the core category vividly showed joys and sorrows of men who had abused alcohol and has lived in the recovering process of managing the yoke of life-long disease. In this process of recovery from alcoholic dependence the men gradually adjusted themselves to their given condition. Also they gained coping strategies to care for, and protect themselves. Therefore health care providers can establish supportive programs in the clinical field to empower these men by reflecting their proactive coping strategies.

This study was conducted to find out how the team organization works and to suggest better ways of applying the team system to a library organization. In this study, the survey was conducted to examine the characteristics of the university libraries that have adopted the team system, and the problems in operation were analysed. The findings indicate that staffs at the university libraries had a comparatively negative image of the team system, and that university library has provided insufficient training and less supports for their staffs in the process of adopting the system. This study might be applicable to any strategy which seeks to reduce bureaucracy, empower staff, create a team system culture. and enhance the delivery of high qualify services.
