        본 논문에서는 최근 미국과 EU의 생성형 AI 영역 협력과 경쟁에 관 하여 분석하였다. 미국 정부는 투명성 보장, 즉 생성형 AI에 의해 제작 된 창작물임을 표시하게 함으로써 표현의 자유를 보장한다. 플랫폼에 대 한 제어 또한 원칙 제시뿐, 유포에 대한 기업의 책임은 면책대상 조항으 로 다루고 있다. 반면, EU가 최종한 AI 규제는 AI 사용에 관한 세계 최 초의 포괄적 AI 규제법이다. EU는 디지털 전략의 일환으로 AI 산업을 규제하여 혁신적 기술 개발 및 사용을 위한 더 나은 조건을 보장하고자 포괄적 입법 과정을 거치고 있다. 본고에서는 양측의 규제는 미국의 경우 ‘원칙 제시 및 자발성’ 규제 유형이며, EU의 경우 ‘규칙 기반, 강제성’ 규 제 유형으로 구분될 수 있음을 제시한다.

        Today’s digital economy has gradually emerged as a new engine of innovation for China’s economic growth. However, while injecting new vitality into the Chinese economy, digital globalization has also brought a series of challenges to China, such as data security, digital divide, unregulated competition among digital platforms, and a lack of mechanisms for protecting property rights. These issues underscore China's insufficient capacity for effectively regulating and systematically governing the digital economy. In contrast, South Korean government has implemented the ‘Korea Digital Strategy’ (KDS) and the ‘Basic Law for Promoting the Revitalization and Utilization of Data’ (Data Industry Act) to foster the development of the digital economy industry. These measures effectively solve the problems of digital industry development and governance, and thus improve the legal system of South Korea’s digital economy. Therefore, this study compares the construction of digital economy legal system in China and South Korea through comparative analysis, summarizes the experience of digital economy legal system construction in South Korea, and offers three insights for the development of China’s digital economy legal system. Firstly, China needs to improve the coordination of its laws for the digital economy, avoid repetitive and overlapping legislation, and enhance the scientificity and authority of legislation; Secondly, China needs to adopt a systematic and comprehensive approach to legislating and governing the digital economy, ensuring the consistency and coherence of the system; Thirdly, China needs to conduct more basic research, pay attention to the ethical and legal implications, and keep the legal system up to date, so as to ensure the effectiveness of the law.

        In this study, we report the microstructural evolution and shear strength of an Sn-Sb alloy, used for die attach process as a solder layer of backside metal (BSM). The Sb content in the binary system was less than 1 at%. A chip with the Sn-Sb BSM was attached to a Ag plated Cu lead frame. The microstructure evolution was investigated after die bonding at 330 °C, die bonding and isothermal heat treatment at 330 °C for 5 min and wire bonding at 260 °C, respectively. At the interface between the chip and lead frame, Ni3Sn4 and Ag3Sn intermetallic compounds (IMCs) layers and pure Sn regions were confirmed after die bonding. When the isothermal heat treatment is conducted, pure Sn regions disappear at the interface because the Sn is consumed to form Ni3Sn4 and Ag3Sn IMCs. After the wire bonding process, the interface is composed of Ni3Sn4, Ag3Sn and (Ag,Cu)3Sn IMCs. The Sn-Sb BSM had a high maximum shear strength of 78.2 MPa, which is higher than the required specification of 6.2 MPa. In addition, it showed good wetting flow.

        In this study, we investigated the dynamic characteristics of three irregular building models to analyze the effectiveness of displacement response control with Tuned Mass Damper (TMD) installation in twisted irregular buildings. The three irregular models were developed with a fixed angle of twist per story at one degree, subjected to three historical seismic loads and resonant harmonic loads. By designing TMDs with linear and dashpot attributes, we varied the total mass ratio of the installed TMDs from 0.00625% to 1.0%, encompassing a total of 10 values. Two TMDs were installed at the center of the top story of the analysis model in both X and Y directions to evaluate displacement response control performance based on TMD installation. Our findings suggest that the top displacement response control performance was most effective when a 1.0% TMD was installed at the top layer of the analysis model.

        This study presents code-compliant seismic details by addressing dry mechanical splices for precast concrete (PC) beam-column connections in the ACI 318-19 code. To this end, critical observations of previous test results on precast beam-column connection specimens with the proposed seismic detail are briefly reported in this study, along with a typical reinforced concrete (RC) monolithic connection. On this basis, nonlinear dynamic models were developed to verify seismic responses of the PC emulative moment-resisting frame systems. As the current design code allows only the emulative design approach, this study aims at identifying the seismic performances of PC moment frame systems depending on their emulative levels, for which two extreme cases were intentionally chosen as the non-emulative (unbonded self-centering with marginal energy dissipation) and fully-emulative connection details. Their corresponding hysteresis models were set by using commercial finite element analysis software. According to the current seismic design provisions, a typical five-story building was designed as a target PC building. Subsequently, nonlinear dynamic time history analyses were performed with seven ground motions to investigate the impact of emulation level or hysteresis models (i.e., energy dissipation performance) on system responses between the emulative and non-emulative PC moment frames. The analytical results showed that both the base shear and story drift ratio were substantially reduced in the emulative system compared to that of the non-emulative one, and it indicates the importance of the code-compliant (i.e., emulative) connection details on the seismic performance of the precast building.

        The objective of this study was to conduct research and analysis using Group Focus Interview to survey the between construction site workers and managers implementing for the Severe Accident Punishment Act. Focused on measures to improve safety management effectiveness for the effectiveness of establishing a safety management system. A plan to improve the efficient safety management system was presented to 50 construction industrial managers and workers. In order to ensure the industrial accident prevention policies appropriately, it is necessary to be aware of safety obligations for workers as well as business operators. In addition, despite the existence of a commentary on the Serious Accident Punishment Act, confusion in the field still persists, so in the event of a major accidents, the obligation to take safety and health education is strengthened, and effective case education is proposed by teaching actual accident cases suitable for actual working sites. It is necessary to make all training mandatory, and it is necessary to reconsider awareness through writing a daily safety log, awareness of risk factors, etc., and writing down risk information. Above all, at the construction ordering stage, it is necessary to keep the construction safety, request corrections and supplements for problems issues that arise, and consult between the orderer and the construction company about the problems issues. Rather than having only the construction company correct or supplement the safety management plan, the contents should be shared with supervisors and workers to establish a more practical solution. Results of this study will contribute to improving the effectiveness of the serious accident and construction safety management system.

        Non-uniform reinforced concrete brace facade systems are newly considered to improve seismic performance of reinforced concrete frame buildings under lateral load. For normal and high strength concrete of 30MPa, 80MPa, and 120MPa, the cross-sections of reinforced concrete brace facade systems were designed as different size with same amount of reinforcements. The strengthened frame systems were analyzed by a non-linear two-dimensional finite element technique which was considering material non-linearities of concrete and reinforcing bars under monotonic and cyclic loadings. From the study of non-linear analysis of the systems, therefore, it was provided that the proposed braced facade systems were reliable to improve laterally load-carrying capacity and minimize damages of concrete members through comparisons of load-displacement curves, crack patterns, and stress distributions of reinforcing bars predicted by current non-linear finite element analysis of frame specimens.

        A Smart factories are systems that enable quick response to customer demands, reduce defect rates, and maximize productivity. They have evolved from manual labor-intensive processes to automation and now to cyber-physical systems with the help of information and communication technology. However, many small and medium-sized enterprises (SMEs) are still unable to implement even the initial stages of smart factories due to various environmental and economic constraints. Additionally, there is a lack of awareness and understanding of the concept of smart factories. To address this issue, the Cooperationbased Smart Factory Construction Support Project was launched. This project is a differentiated support project that provides customized programs based on the size and level of the company. Research has been conducted to analyze the impact of this project on participating and non-participating companies. The study aims to determine the effectiveness of the support policy and suggest efficient measures for improvement. Furthermore, the research aims to provide direction for future support projects to enhance the manufacturing competitiveness of SMEs. Ultimately, the goal is to improve the overall manufacturing industry and drive innovation.

        This study divided the area capable of producing domestic forage into grazing pasture, hay production area, and silage crop area, calculated the required area according to the forage production volume, and examined whether self-sufficiency in forage leads to cost savings. When the self-sufficiency rate of forage for dairy cows and Hanwoo is 80%, the improvement in profitability per heaf ranges from 3% to 9%, typically around 5%, which is considered a significant benefit for both corporate and individual businesses. The average profit per ranch is expected to increase about KRW 50 million per year, and the country as a whole is expected to reduce forage costs by KRW 0.9 trillion per year. Recently, efforts are being made by the government and local authorities to cultivate summer forage at the rice fields for improving self-sufficiency in forage feed to stabilize rice supply and demand. Furthermore, it is also necessary to conduct research on reducing the cost of concentrated feed and TMR (Total mixed ration).

        In ecosystems within limited resources, interspecific competition is inevitable, often leading to the competitive exclusion of inferior species. This study aims to provide foundational information for the conservation and restoration management of Microphysogobio rapidus by evaluating species’ ecological response to biological factors within its habitat. To understand this relationship, we collected food web organisms from site where M. rapidus coexist with Microphysogobio yaluensis, a specie ecologically similar to M. rapidus, and evaluated the trophic levels (TL), isotopic niche space (INS), and the overlap of INS among fishes within the habitat using stable isotope analysis. Our analysis revealed that the M. rapidus exhibited a higher TL than M. yaluensis, with TL of 2.6 and 2.4, respectively. M. yaluensis exhibited a broad INS, significantly influencing the feeding characteristics of most fish. Conversely, M. rapidus showed a narrow INS and asymmetric feeding relationships with other species, in habitats with high competition levels. This feeding characteristics of M. rapidus indicate that the increase in competitors sharing the similar resources lead to a decrease in available resources and, consequently, is expected to result in a decrease in their density.

        With the increasing cultural exchanges, ethnic exchanges and international exchanges in the 21st century, the distance between countries and peoples has been gradually narrowed, and it is the urgent desire of every country to achieve peace, stability and development together. In this international situation, a new idea, “multicultural education”, has been born, which is to safeguard and protect the equal and common right to education of people of all countries by means of the power of education. One of the main objectives of multicultural education is to provide students with the necessary knowledge, culture and skills to help them better stand firm in the context of different ethnic cultures, community cultures, social mainstream cultures and cross-ethnic cultures, aiming to eliminate the concept of integration or homogenization, and avoid seeing all students as individuals with the same cultural background and experience. It’s about respecting and acknowledging their diversity. Multicultural education is not only a process of educational reform, but also a positive educational idea or value concept, which is of great significance to modern society and an important way to meet the diversified needs of students and improve the quality of education. At the same time, it also helps to cultivate students’ understanding and respect for different cultures and promotes the development of global citizenship. The concept of multicultural education has been clearly reflected in many disciplines, and the field of art is no exception. This concept emphasizes the importance of arts education in promoting cultural diversity and national identity. Through exposure to and learning about the music of different countries, nationalities and regions, students can also better understand and appreciate the value and uniqueness of various cultures, while strengthening their identity and pride in their own culture. From the perspective of multi-culture, Chinese music education has experienced a series of changes and development in the past period of time, and at the same time ushered in unprecedented opportunities and challenges. According to relevant research findings, China began to explore and study multicultural music education many years ago, and although it has made some achievements, there are still many problems. Based on this, this paper summarizes the problems exposed by Chinese music education under the multicultural situation, and explores and analyzes how to achieve better and more long-term development of Chinese music education under the multicultural perspective based on these problems.
