This study was conducted to analyze the correlation between egg breakage rate and cumulative external forces on eggs during the egg transfer system in 12 commercial layers farms. The commercially available electronic egg device was used to detect the external forces on eggs during egg collection systems. In addition, egg breakage rate per farm was collected. It was found that the external force on eggs were greater in the order of washer and dryer connection part, conveyor connection part, transfer, sorter, collecting elevator, packer, egg transfer connection part, and egg tray. A positive relationship between the external forces on eggs during egg transit system and the incidence of cracked eggs per farm was noted. The external forces on eggs varied from 5G to 38G depending on the location and the egg breakage rate ranged from 3.2 to 14.5% per farm. Although efforts to produce eggs with high eggshell quality are considered important, extra care should be made to lower the external forces on eggs during the egg transfer system from laying house to egg packing center.

Universities that previously targeted in 20s have recently diversified their operation methods, founding purposes, and target. With a significant decrease in the school-age population relative to the number of universities, universities are making their best efforts to secure new students and minimize student attrition. In this study, an online survey was conducted to empirically examine the effects of motivation for major selection and sense of belonging on learning persistence intention among students in beauty-related departments at 2-year and 4-year general universities and cyber universities. The collected data from 119 students at general universities and 113 students at cyber universities were analyzed using SPSS 28. The key findings can be summarized as follows: For general universities, motivation for major selection did not have a significant effect on learning persistence intention, but sense of belonging had a significant positive effect. Additionally, an interaction effect was observed, indicating that as the sense of belonging increased, extrinsic motivation significantly increased learning persistence intention. For cyber universities, intrinsic motivation and sense of belonging among motivations for major selection had a significant positive effect on learning persistence intention, while the moderating effect of sense of belonging in the relationship between motivation for major selection and learning persistence intention was not significant. In summary, for general universities, the factor that influenced students' learning persistence intention was a sense of belonging to the university, while for cyber universities, intrinsic motivation played a significant role. These findings are expected to provide meaningful insights and data for universities to develop effective policies for preventing student attrition.

Due to the nature of electric vehicles, the batteries used for electric vehicles have a very large rated capacity. If an electric vehicle runs for a long time or an electric vehicle is abandoned due to a traffic accident, the electric vehicle battery becomes a waste battery. Even in vehicles that are being abandoned, the remaining capacity of waste batteries for electric vehicles is sufficient for other purposes. Waste batteries for automobiles are very expensive, so they need to be recycled and reused, but there was a problem that the standards for measuring the performance grade of waste batteries for recycling and reuse were insufficient. As a method for measuring the remaining capacity of waste battery, the most stable and reliable method is to measure the remaining capacity of battery using full charge and discharge. However, the inspection method by the full charging and discharging method varies depending on the capacity of the battery, but it takes more than a day to inspect, and many people are making great efforts to solve this problem. In this paper, an electric vehicle battery residual capacity analysis technique using voltage deviation between cells was studied and analyzed as a method to reduce inspection time for electric vehicle batteries. To this end, a full charging and discharging-based capacity measurement system was constructed, experimental data were collected using a nose or waste battery, and the correlation between the voltage deviation and the remaining capacity of the battery pack was analyzed to verify whether it can be used for battery inspection.

Radical changes in modern society have influenced on the nature of the works and the importance of the career education is emphasized more than any time. Various scholars have continuously emphasized the importance of the career education in regular schools. Most career educations in regular schools, however, consist of one-time event-oriented programs because of the systematic limitations immanent in Korean school system. To overcome the limitations of the school system, scholars have contended that career educations in regular schools should be integrated into the existing subjects and the curricula. Therefore, it is necessary to analyze exemplary cases of the career education through the subjects integration in developed countries. The target of the analysis in this study was the career education related content in Australia because Australian federal and local governments have made great efforts in integrating the career education into the regular school curricula. With interviews and literature analysis, the current status of the career education through the subjects integration in federal and local governmental levels and the career education related contents in the regular school curricula of local governmental level were analyzed. Major findings of the study were as follows: 1) Career education components were mainly contained in the PDHPE(personal development, health and physical education) subject in New South Wales; 2) Understandings of a wide range of work were emphasized in the cross-curricular perspective in South Australia; 3) Career education components were mainly contained in the SOSE(studies of society and environment) subject in Victoria; and 4) Career education related contents were integrated mainly in the 'inner learner' unit in Essential Learning subject in Northern Territory. The conclusions were derived from the outcomes of the study and the recommendations were proposed for the applications of the study results and the future researches.

Through specific cases, this article examines the causes and measures to overcome cultural divergences most frequently encountered by Koreans living in Vietnam and Korean-contacting Vietnamese in terms of mode of communication, mode of living and mode of doing business. Historical reality proves that Vietnam and Korea have a lot in common in history, culture and society, due to the influence from the Chinese culture on both countries. However, each country has its own acculturation, hence, there exist, apart from the normal dissimilarities, differences between the two countries especially in natural environment andpolitical systems. As a result, in Vietnam, Koreans and Vietnamese have met with quite a lot of divergences in communication, business and living activities. In order to overcome these cultural divergences, in addition to the ceaseless efforts made by Koreans in Vietnam and Korean-contacting Vietnamese, there should be concern, assistance as well as cooperation between the people and the authorities of the two countries. We should draw lessons from the groundless or trivial affairs which, springing from the Chinese people's dislike for Koreans, have been blown up and disseminated on the internet; where by we are to reconsider the relationship between Koreans and Vietnamese. What is more, Korea still feels historically ashamed to have sent nearly 350,000 soldiers to the wa rin Vietnam for economic purposes in the past. As our predecessors brought about that historic shame to get bread for our fatherland in exchange, our generation today should approach Vietnam out of a sense of responsibility towards history. Having experienced a period of economic difficulties, Vietnam innovated and started its open-door policy in 1987. However, this event should not be regarded as the reason for us to approach Vietnam with only one rigid economic principle.

So far there has been a strong tendency to study The Great Learning in terms of quite" limited ethical and moral understandings." Yet The Great Learning was originally a political text to educate the ruler. So the ethical and moral understanding discussed in the book should be interpreted as something more comprehensive and practical, which includes the political ability. This paper thus focuses on this new line of understanding of The Great Learning. Among the three principles of the book, 'Myeongmyeongdeok( 明明德)' means the virtue of a politician, that is to 'cultivate (Myeong)' the 'properties for a statesman (Myeongdeok).' 'Sinmin (新民)' means 'to innovate or reform the people as a result of substantive administration of a politician'. 'Jieojiseon (止於至善)' means 'to reach and to maintain the highest degree of goodness as a result of Myeongmyeongdeok and Sinmin'. These three principles would divide into eight practicums. Myeongmyeongdeok would divide into five steps of 'Sugi(修己: Cultivating the self)' practicum, which are 'Gyeokmul (格物) → Chiji(致知) → Seongeui(誠意)→ Jeongsim (正心)→ Susin (修身)'. Sinmin would divide into three steps of 'Chiin (治人: rule the people)' practicum which are 'Jega(齊家) → Chiguk(治國) → Pyeongcheonha(平天下).' And the point where the two practicums are harmonized, i.e. that of Sugichiin (修己治人), is the place of Jieojiseon. Not every ethical people become a politician but every politician must be ethical. That is the assertion of the Great Learning.

$CO_2$ 20세기 초 천연 냉매 $CO_2$는 광범위하게 사용되었지만 프레온계 냉매의 출현으로 1940년경부터 $CO_2$냉매는 사용이 제한되었다. 그러나 반 세기 동안 사라졌던 $CO_2$냉매는 1980년 후반에 노르웨이 과학 기술대학 (NTNU)과 북구 최대 민간연구소 (SINTEF)의 Lorentzen 교수에 의해 $CO_2$천연 냉매 사용을 재고하게 되었다. 프레온계 냉매의 환경적 논쟁이 쟁점이 되면서 천연 냉매 사용을 재고하게 되었다. 특히 비가연성과 비유독성으로 인한 $CO_2$냉매가 주목을 받고 있다. 초월임계 사이클레서의 고압 제어에 대한 새로운 개념은 Lorentzen 교수와 동료 연구원에 의해서 특허로 제안되었다. 이에 대한 상업적 권리를 Norsk Hydro사는 1990년에 얻었고,1990년대 초반에 NTNU/SINTEF의 공동 연구개발 프로그램을 통해 기술 경쟁력과 실현 가능성이 검증되었다. 현재 연구소에서는 최초로 초월임계 $CO_2$사이클을 이용한 상업용 온수 열펌프 시스템, 2003년 시작할 연료전지 전기 자동차에 대한 연구를 수행하고 있다.

Recently, United Nations found that 38% of global carbon emissions are generated in the building sector, surpassing other industries (32%) and transportation (23%), and ESG is actively used as a way to reduce carbon emissions in the building sector, led by overseas advanced countries. In Korea, as the National Pension Service announced "Consider ESG with more than 50% of investment assets" this year, the move to introduce ESG in the building sector is accelerating, centering on construction companies and asset management companies. However, as the domestic ESG evaluation system is still mainly focused on corporate governance and social responsibility, interest in the environmental sector is lagging behind that of advanced countries. As ESG in the building sector is expected to grow rapidly over the next 10 years, I would like to suggest the following development directions. The first is the expansion of the incentive system. In order for the government to successfully implement policies related to ESG in the building sector, incentive system such as tax reduction and building standards should be expanded further than now in addition to negative systems such as rent restrictions and punishment taxes due to regulatory violations. Second, standardized ESG standards are established. Rather than creating an independent Korean ESG standard that is far from global standards, it is necessary to organize the common parts of global standards and evaluation methods and create and provide guidelines in the form of standard textbooks that can be used equally by all stakeholders. Third, it is an effort to link ESG in the building sector with Digital Transformation(DX). This is because actual energy savings and carbon emission reduction can be realized only when the operation method of the building sector, which is operated mainly by manpower, is digitalized and converted to an intelligent way.

The purpose of this study is to find out the experience and meaning of discrimination among Korean-Chinese part-time job international students. To this end, after in-depth interviews with nine Korean-Chinese part-time job international students from May to June 2022, the data were analyzed using Colaizzi's phenomenological research method. The findings were as follows: New challenges for living expenses and efficient adaptation, this road full of thorns, efforts to adapt beyond discrimination, growth and relationships through part-time jobs turned out to be opportunities. This experience became a process for Korean-Chinese part-time international students to grow further as well as solve economic problems. However, they are subject to multiple discrimination due to their dual status as international students and ethnic Korean-Chinese. Their Korean identity gives a more directed differential experience in the process of working part-time. But in the process, they are still overcoming difficulties. Korean-Chinese international students are growing up by accepting discrimination experiences and adapting to their international life. As a result of the above research, we need education and help to guarantee working human rights for Korean-Chinese part-time students with the development of a multicultural society in the future.
