Design of solar array with sun position tracking system employing refrigerant

Renewable energy is quickly gaining relevance as a source of energy as the price of fossil fuels changes. As the need for electricity has risen in recent years, the power sector has played an increasingly important role in our daily lives. Solar power is one of the most important renewable energy sources on the planet, and it should be collected and exploited to its full potential. The proposed system is unique in that it uses the sun instead of the earth as a guiding source. Solar panels' energy conversion efficiency is determined on the amount of sunshine they receive. As a result, a tracker device must be designed to make sure that the solar panel's direction always follows the sun's location. As a result, we're attempting to design a solar array with a sun position tracking system that can provide or consume the most solar energy while maintaining a reasonable potency. There are a variety of ways to track the sun's location, but we prefer to utilize the passive method. Instead of using external energy to detect the sun's position, passive solar tracking employs refrigerant as a source. It operates on the concept that when the temperature rises, the refrigerant's vapour pressure rises as well. The transfer of high-pressure refrigerant from one canister to another generates an imbalance in the weights on the canisters, allowing them to track the position of the sun.

Design of Korean Culture Teaching and Learning Based on Intercultural Education: Focusing on intertextuality using swan maiden

In order to design Korean language culture teaching and learning based on intercultural education, this study selected “The Fairy and the Woodcutter” corresponding to the world-class folktale transmission type swan maiden, and surveyed and reflected the perceptions of Chinese and Vietnamese learners twice. The real culture of foreign learners was reflected in teaching and learning by investigating the commonalities and differences between “The Fairy and the Woodcutter-牛郎 織女-Ngưu lang Chức nữ” that the people of “Korea-China-Vietnam” commonly know. In addition, it was intended to promote learners intercultural capabilities by considering Byram and the Korean Language Education Standard Model Development Process, which emphasized the improvement of intercultural cultural communication capabilities of both learners and instructors in foreign language education. These efforts are meaningful in that they have been actively carried out using folk tales in Korean language education, expanding the interpretive horizon of Korean language culture education.
Exploring the Direction of Cultural Heritage Education in Schools for the Enjoyment of Culture

This study aims to propose the direction of teaching cultural heritages at the music class in schools following the perspective that cultural heritage education should lead to ‘cultural enjoyment’. In this study, the definition of cultural enjoyment that can be applied in school education is considered as ‘the intellectual, emotional, practical process and its results that an individual actively seeks to understand and experience culture,’ and three attributes of ‘activity, positive sentiment, and participation’ are presented as those of cultural enjoyment.&#x0D; As a result of analyzing the current status and problems of cultural heritage education in schools, the following problems were identified: ‘curriculum standards centered on research and presentation,’ ‘curriculum standards limited to appreciation and value recognition,’ ‘textbook contents biased towards data presentation and information delivery,’ and ‘inadequate provision of musical experiences for learning cultural heritages.’ To solve such problems and increase the possibility of achieving the goal of 'enjoying culture' in school education, we propose three aspects in cultural heritage education: establishing goals for cultural heritage education that promote the development of 'subjectivity in creating'; setting up a content framework for cultural heritage education centered on 'enjoyment'; and enhancing the ability to enjoy culture based on participatory cultural heritage learning.&#x0D; The significance of this study is to raise the need for cultural heritage education in schools to move in the direction of enhancing learners' ability to enjoy culture, and to discuss the direction for this. To solve the problems raised in this study, it is important to achieve social consensus on cultural heritage, revise national education curricula, develop music textbooks, and cooperate with institutions related to cultural heritage education
A Study on the Science and Engineering Writing Education Using Technical Writing: Focusing on Improving Communication and Ethical Capabilities
