The purpose of this study is to analyze widely how the higher education of China introduced market mechanism, adjusted and changed its structure, and what is its characteristic today. The market-orientedness of China's higher education has been strengthened as the direction of Chinese socialism was converted to the improvement of productivity and Socialist's Market Economy proceeded. It developed gradually from the experimental stage of the introduction of market economy, through its real introduction stage and the stage of strengthening of market-orientedness, and finally to the deepening and development stage. Through these processes, China's higher education has got the characteristic of market-orientedness. It is being improved for the strengthening of autonomy, privatization, and raising of competitiveness and has China's unique local trait.

All research methodologies have a certain research purpose and application range. Therefore, it cannot be conclusively said that some methodologies are superior. Each research methodology has only different research purposes and application ranges. The various theories and methodologies related to the study of Chinese dialect sounds have not been in a confrontational relationship with each other. But the need for analysis of new phenomena has led to the emergence of new methodologies and it has been deepening the depth of the study together, supplementing the theories of the past. The emergence of new theories and methodologies has not only always provided another means for dialect analysis methods, but has also deepened awareness of the changing rules of dialects, the interrelationships between rules and the causes of change. The Chinese dialect is richly embedded in various phenomena that can be seen in human languages. In analyzing the phenomenon of the Chinese dialect, we should first closely observe and judge whether it is the result of internal historical changes in the dialect itself or changes formed by contact or influence with the external dialect, and apply the analytical method accordingly. Sometimes there is a phenomenon formed by a number of complex factors, not one, that requires a comprehensive analysis that combines a variety of theories and methodologies.

This research investigates how users of Bilibili, a video sharing website based in China have responded to carbon neutrality. By conducting quantitative textual analyses on 3,311 comments on Bilibili using LDA topic extraction and content statistics, this research discovers that: (1) Bilibili users have assigned more weight to geopolitical topics (56.3%) than energy (22.0%) and environmental topics (21.7%). (2) When assessing carbon neutrality, Bilibili users considered geopolitical (53.8%) and energy factors (15.8%) more heavily than factors related to the class (9.2%), economy (8.9%), environment (8.7%), and definition (3.6%). (3) More Bilibili users had negative (64.6%) attitudes towards carbon neutrality, with only a small portion of them expressing positive (26.8%) and neutral (8.6%) attitudes. (4) Negative attitudes towards carbon neutrality were mainly driven by geopolitical concerns about the West's approach to China, other countries' free-riding on China's efforts and the West's manipulation of rules, doubts about the feasibility of energy transition and suspicion of capitalists exploiting consumers through this concept. This research highlights the geopolitical concerns behind the environmental attitudes of Chinese people, deepening our understanding to psychological constructs and crisis sensitivity of Chinese people towards environmental issues.

The Baltic Capesize Index (BCI), which is used as an indicator for marine transportation of steel raw materials, is one of the key economic indexes for managing the risk of loss due to rapid market fluctuations when steel companies establish business strategies and procuring plans for raw materials. Still, the conditions of supply and demand of steel raw materials has been extremely affected by volatility shocks from drastic events like the financial crisis such as the Lehman Brothers incident and changes in the external environment such as COVID-19. And, especially since the 2008 financial crisis, endeavors to predict the market conditions of the steel raw material is becoming more and more arduous for the deepening uncertainty and increased volatility of BCI, which has been used as a leading indicator of the real economy. This study investigates the correlation between the steel raw material market and the marine transportation market by estimating the spillover effect of information between markets. The vector error correction model (VECM) was used to analyze information transfer based on the correlation between the BCI and crude steel production, capesize fleet supply, raw material price, and cargo volume.

The mourning attire worn by the Sangju (Chief Mourner) during Confucian funeral rituals is known as Gulgeonjebok. It is comprised of Gulgeon, Sujil, and Hyogeon on the head, and Jungui underneath. On top of the Jungui, the ceremonial garments called Choeui are worn, along with Choesang. Yojil and Gyodae are then tied around the waist. Mahye and Hangieon are worn on the feet, and a walking stick made of bamboo, paulownia, or willow is carried. A needlework master, Choe Onsun, who was designated as a Holder of Intangible Cultural Property of Jeollabuk-do on November 27, 1998, is recognized for her efforts in restoring and recreating the forgotten Gulgeonjebok. Thanks to her endeavors, the period, regional, and cultural characteristics of Gulgeonjebok in the Jeolla Province have been preserved. This study aims to examine and reproduce characteristic items of Gulgeonjeboks handed down by a needlework master, Choe, by conducting an empirical study on the dimensions and schematization of the Gulgeon, the method of cutting, and the sewing process. The empirical research on Gulgeojebok is expected to further enhance traditional sewing skills. It will also serve as a foundation for deepening the level of research on traditional dress and sharing traditional cultural heritage.

This article argued for the need for a transformation of archives system and archival science through a review of the archival circles' discussion of dismantling and reconstructing the current national archive system. By sharply contrasting the cases of civil society 'archiving activities' with the cases of 'national archive sites', we attempted to present solutions to the current archive system from a micro perspective. In this process, the need for a shift in archival research methodology centered on archival materials was derived in relation to the deepening of awareness of archival information organization and hierarchical description to ensure archive accessibility and the meaning of policy shift.

With the rapid development of highways and railways, series of traffic safety issues emerged because of mudstone disintegration. To research on the mechanism and further guarantee the stability and safety of transportation infrastructure built on or near mudstone formations, the mudstone disintegration test of mudstone was carried out based on mudstone and sandy mudstone. The element types, cementation characteristics and pore characteristics of the tested specimens were studied by means of Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and Image Pro Plus (IPP). The disintegration index of mudstone was approximately 1%, and even some specimens were difficult to be calculated, while the disintegration index of sandy mudstone is approximately 8.7%. According to the results, the two mudstones belong to grade II and III disintegration respectively, of which the sandy stone presents more extensive disintegration than mudstone. This phenomenon was distinguished that, the clay minerals of mudstone are approximately 25% more abundant than those of sandy mudstone, and the unit pore area is 20 ㎛² larger, which result in different microstructure and water absorption capacities. In the liquid phase, the ions in the mudstone specimens were exchanged and combined with water molecules in the environment during the whole disintegration process. This results in continuous spalling and fragmentation of clay minerals, the emergence of secondary fractures, and the deepening of primary fractures.

-In recent years, unmanned underwater vehicles (UUV) have been vigorously developed, and with the continuous deepening of marine exploration, traditional energy can no longer meet the energy supply. Nuclear energy can achieve a huge and sustainable energy supply. The heat pipe reactor has no flow system and related auxiliary systems, and the supporting mechanical moving parts are greatly reduced, the noise is relatively small, and the system is simpler and more reliable. It is more favorable for the control of unmanned systems. The use of heat pipe reactors in unmanned underwater vehicles can meet the needs for highly compact, long-life, unmanned, highly reliable, ultra-quiet power supplies. In this paper, a heat pipe reactor scheme named UPR-S that can be applied to unmanned underwater vehicles is designed. The reactor core can provide 1 MW of thermal power, and it can operate at full power for 5 years. UPR-S has negative reactive feedback, it has inherent safety. The temperature and stress of the reactor are within the limits of the material, and the core safety can still be guaranteed when the two heat pipes are failed.

Complexity science is a new stage in the development of systems science that is the frontier areas of contemporary scientific development. Complexity science takes complex systems as the research object, which has attracted widespread attention from researchers in the fields of economy, control, management, and society. In recent years, with the rapid development of science and technology and people's deepening understanding for the theory of complex systems, the systems are no longer an object with a single function, but the systems are composed of multiple individuals with autonomous capabilities through cooperative and cooperation, namely multi-agent system (MAS). Currently, MAS is one of the main models for studying such complex systems. The intelligent control is to break the traditional multi-agent fault-tolerant control (FTC) concept and produce a new type of compensation mechanism. In this paper, the applications of fault-tolerant control methods for MASs are presented, and a discussion is given about development and challenges in this field.
