2022 marks the thirtieth year of diplomatic relations between China and South Korea. Two countries’ relations are not only one of the most important state-to-state relations in East Asia, but also important relations that attract the attention of all over the world. This research used CiteSpace 5.8.R3 software to extract relevant papers on China-Korea relations from CNKI, a representative academic database in China. By extracting authors, institutions, keywords and other elements, this research focused on how the research on China-Korea relations in CAC is carried out and what kind of characteristics it has. This research found that in terms of the total amount, the number of academic achievements of CAC on China-Korea relations is not large, and China-Korea relations have not been the main focus of the CAC. From the perspective of scholars and institutions, CAC have not yet formed a core scholar and core scientific research institution. Judging from the keyword analysis, CAC have involved various fields of China-Korea relations, but their focus was mainly on the major events that happened each year, scholars’ vision was not broad enough, meanwhile the focus did not last long enough.

In the modern society, the sports industry is becoming an important industry that plays an important role in cultural exchange and economic development between countries. Along with this, the size of sports equipment manufacturers is also increasing, and especially in the archery field, domestic companies occupy a high share in the global market. However, in the case of precision accessories, foreign products are imported and used. Among the precision archery accessories, the cushion plunger is subjected to repetitive loads, and the surface damage due to wear affects the accuracy of the archery, so fatigue and wear analysis taking this into account are required. In this paper, a friction simulation was performed to calculate the fatigue life and wear amount of the cushion plunger among the precision archery accessories, and the validity of the analysis model was evaluated by comparing the friction test results.

The research aimed to develop a high-efficiency plate-type heat exchanger for exhaust gas using computational fluid dynamics (CFD) thermal analysis based on the plate shape, and to identify the optimal shape. Following this, a water/air plate heat exchanger was manufactured, and its characteristics were studied experimentally. As the Re number increases on the gas (or air) side, the heat transfer rate increases significantly, whereas an increase in the Re number on the water side leads to a smaller increase in heat transfer. This is attributed to the larger convective heat resistance on the gas side, causing a substantial reduction in gas-side heat resistance as gas velocity increases, resulting in a considerable overall reduction in heat resistance. The fluid flow pressure drop showed similar results between the CFD calculations and experimental outcomes.

The economic harm and survival fear caused by environmental conflicts are most likely to become the psychological lever to drive individuals to adopt environmentally friendly behaviours. From the perspective of environmental conflict, this paper will explore the transmission mechanism of environmental conflict on individuals’ pro-environmental behaviour through three experiments.

This research not only determined the preference of fashion brand distribution channels of active Korean and Chinese seniors who became major consumers in the fashion industry, but also analyzed the effect on these preferences and choices of distribution channels depending on personal consumption characteristics and differences between the two groups. Data was collected by a professional survey firm. SPSS 24.0 and AMOS 24.0 were used for empirical analysis, and frequency analysis, multiple response analysis, EFA, reliability analysis, CFA, SEM, and multiple-group comparison analysis were performed. As a result of multiple response analysis, the offline channel was revealed as the preferred fashion distribution channel for active Korean and Chinese seniors; the second most popular was the online channel. The results of multiple-group comparison analysis reveal differences between two groups in seeking emotional consumption via the offline channel; the effect was only evident for active Korean seniors. A difference in seeking emotional consumption via preference for online channel also existed, but only for active Chinese seniors. For these reasons, marketers targeting active Korean seniors will be effective to not only offer brand information by fashion display to let seniors understand the fashion brand, but also to have brand events to form positive emotions toward the fashion brand. Moreover, targeting active Chinese seniors will be necessary to transmit brand sensibility by utilizing metaverse marketing comprising various factors, so that consumers can enjoy the fashion brand.

본 연구에서는 최근 가속화되고 있는 기후변화로 인하여 쇠퇴가 우려되는 설악산 분비나무림을 대상으로 식물사회학적 연구를 수행하였다. 현장조사에서 획득된 70개 방형구 조사결과에 대해 TWINSPAN 기법을 이용하여 군락을 분류하고, DCA 방법으로 서열을 분석한 후 각 군락이 갖는 특성을 분석하였다. 설악산 분비나무림은 4개 군락(분비나무-댕댕이나무군 락, 분비나무-시닥나무군락, 분비나무-당단풍나무군락, 분비나무-거제수나무군락)으로 구분되었다. 각 군락은 입지에 따라 분포 유형을 달리하였으며, 이는 해발고도, 사면 등 입지환경에 따라 서로 다른 미소환경이 형성됨으로써 종조성이 달리지기 때문이다. 각 군락은 분포 고도, 암석비율, 토양특성, 낙엽층 두께 등의 환경에서 차이를 보였으며, 그 결과로 종구성의 차이뿐만 아니라 출현종수 및 개체수, 식피율, 수목규격, 종다양도 등에서 군락 간 유의미한 차이를 보였다. 분비나무-댕댕이나 무군락과 분비나무-시닥나무군락은 높은 고도의 암석비율이 높은 곳에 입지하며 교목층 발달이 미약하였다. 반면, 분비나무-당 단풍나무군락과 분비나무-거제수나무군락은 분포 고도가 상대적으로 낮고 토양비율이 높았으며, 교목층이 발달하고 종다양도가 높게 나타났다.

Jaemulbo (Caiwupu) is a dictionary rich in words, and has the nature of an encyclopedia. Giving a brief description of the collection and interpretation of the terms of plants and animals and observing the acceptance of the Chinese characters and words in the Korean Peninsula, this article singles out four myeongmul (meibutsu) words for textual research in order to observe the characteristics of vocabulary spread to ancient Korea. It has four main objectives. The first is to support the authoritative theory. The second is to ignore character and word relationships that lead to errors although scholars know that glyphs can be used universally. The third is to be cautious not to follow them blindly. The last is to influence the culture of the nation’s famous objects. It is expected that this research can make a significant contribution to the future studies on the spread of Chinese characters.

The research vessel NARA equipped with an azimuth thruster system was built in 2015. There are few vessels with this propulsion system in Korea. This vessel has two modes such as the normal for maneuvering and the power for investigation, and the other two modes as one axis and two axes on the operating. This type of vessels does not seem to have a clear grasp of the maneuvering character in comparison with the vessel with a conventional propulsion system. So the authors carried out the sea test for the turning, the zigzag and the inclination, and the results are as follows. In turning test, the case of using the two axes mode is much better than the case of using the one axis mode for the elements of turning, such as advance, transfer, tactical diameter and final diameter, but turning hard over the rudder in full speed is very vulnerable to capsize in both modes. In zigzag test, the yaw quicking responsibility index,  is very large excessively, which means a bad counter maneuvering ability, so an operator has to keep in mind that in turning operation. If necessary to avoid collision at head on situation, it may be a more effective method to use the crash astern stop than the turning according to the conditions and circumstances for the shortest stopping distance is very short.
