Blended Learning is one of the most popular methods in education for encouraging active learning and improving student learning effectiveness, and it is regarded as one of the most effective methods for universities to attract students. Based on the cultural dimension theory, this paper examined blended learning research trends in both South Korea and China, which are culturally similar but also differ. The research methods include keyword analysis and visualization. Academic papers on blended learning indexed by WoS, KISS, and CNKI from 1990 to June 2022 were collected and analyzed. According to the findings, since the outbreak of COVID-19, the common research topic of blended learning has been subdivided by forming clusters in various research fields. Korea and China exhibit similarities to global research trends while exhibiting differences based on cultural background. The cultural dimension theory-based analysis reveals a common pattern that is especially long-term oriented. The findings can suggest significant implications for designing what role national culture plays in forming patterns of education and research and for developing blended learning with effective impacts in a multicultural educational environment.

The contents of prescription service were comparatively analysed between health centers(HC) and private clinics(PC). Medical chart review was done for 330 otu-patients diagnosed with upper respiratory tract infection(UR) of 120 adults and 90 children, and gastritis or duodenitis of 120 adults. Emphasis on comparison was the prime cost of medication which used in prescription service. The results were as follows; 1. The prime costs fro the medication per visit of HC group were significantly higher than PC group in all three diseases, and the out of pocket payments of patients per visit were significantly lower in the HC group than PC group. 2. The reason for high prime costs of medication per visit of HC in adult case of URI were due to the idverse use of medication and long prescription period per visit. And high medication costs in children cases of URI in HC group were due to the longer prescription day. In cases of gastritis, the prime cost of medication was also higher because of longer prescription period and the higher prime cost of medication. The proportions of medications for injection in the HC and PC groups showed similar features. 3. In depth analysis of the prescription services showed the differences of the contents of medication. In adults cases of URI, the averaged cost of oral medication was significantly lower in HC group, but that of medication for injection was higher in HC group. In children cases of URI, the averaged cost of oral medication and medication for injection was lower in HC group than in PC group. But in the cases of gastritis it was was higher in HC group than in PC group. The prescription periods were longer in HC group than in PC group in all three diseases. As a conclusion prime medication cost and quality of prescription services of HC group were higher than PC group. In terms of health care the cost containment and quality assurance in physician visit for common disease, public sector utilization is good option for those perspectives. But it should not be generalized unless future study about structure and outcome research for quality assurance.

Recently, for the stabilization estimation of structures, many automatic measuring instruments with expensiveness and high accuracy have been developed and utilized. However, the existing manual measuring systems are almost impossible to measure the real-time for the whole surface of large-scale structures and an automatic measuring system has disadvantages with demanding enormous expense. In this study, 3D digital visual monitoring system was developed by using digital photogrammetry technique. To confirm application of developed system, it was applied to the measurement of the wall displacement of concrete surface and displacement measurement of reinforced-soil wall block. Then, the result of the test was compared with measuring value of total station. Based on the results of the comparison, the application of visual monitoring system was evaluated. The results show that the developed visual monitoring system could be available in displacement measure of structures.

Due to COVID-19, the non-face-to-face era has arrived, and telemedicine has become a demand of the times in the medical community. Accordingly, this study aims to present a way to supplement Korea's telemedicine policy by comparing and analyzing domestic telemedicine policy and China's telemedicine policy, and analyzing the success factors of Chinese telemedicine. Domestic and foreign literature was explored to compare and analyze telemedicine policy cases of Korean, Chinese. Domestic and foreign national legal databases and web DBs were used, and literature were restricted between 2009 and 2022. Prior to COVID-19, the scope of telemedicine was very narrow in Korea, and only some pilot projects were operated. After COVID-19, the scope of telemedicine temporarily expanded, but no specific policies or systems were prepared. On the other hand, in the case of China, related policy institutional discussions on telemedicine have been actively conducted since the past, and accordingly, specific scope of application and related management norms and systems have been prepared. For the development of telemedicine in Korea, it is necessary to supplement the definition of telemedicine, ensure the accuracy and safety of non-face-to-face care through telemedicine, and solve the concentration phenomenon of large hospitals through limited conditions for hospital-level medical institutions.

In this study, the characteristics of various raw hairs used for traditional Korean brushes were examined; further, the characteristics and deterioration patterns of Korean, Chinese, and Japanese brushes were compared, with a quantitative evaluation to assess the brush performance. The tensile strength was generally found to be higher with a greater fiber thickness. Among the hairs examined, the back and flank hair of goat was more damaged than that in other parts, and the tensile strength was low. Higher elasticity of the brush made with hair of high cysteine content was measured. Owing to deterioration by use of the brushes, artificial drying brushes had a higher yellowness index and lower tensile strength than natural drying brushes. Further, it was confirmed that brushes with good absorbency exhibited good consistency, but not good elasticity. Thus, the performance of the brush can be influenced by the kind of material used and the brush usage pattern. In addition, it is possible to identify the material science characteristics of brushes which have been produced only by experience; therefore, the results of this study could provide basic data for manufacturing brushes employed in conservation treatment, in the future.

The present study aimed to understand the taste of literati appearing in the Korean-Chinese garden by comparing "Yanghwasorok(養花小錄)" and "Zhangwuzhi(長物志)", which are one of the representative gardens in Korea and China. The main subject of comparison is plants; the research results are as follows. First, Gang Hui-an stated that the ultimate purpose of growing and appreciating the gardening plants is the completion of oneself, while Wen Zhen-heng(文震亨) used gardening plants as a means to practice a life of reclusiveness(隱逸). Second, Gang Hui-an claimed that growing plants is human's cultivation of virtue on the basis of Confucian view's gaining knowledge by the study of things(格物致知), whereas Wen Zhen-heng realized the taste of 'elegance(雅趣)' through form of plants or planting method. Third, although plant preference of literati of both countries is similar in many parts, there is a slight difference for putting gardening plants in pots and appreciating them. For example, even for selecting or placing pots, simplicity and lightness are characteristically reflected from Gang Hui-an while splendor and refinedness are characteristically shown from Wen Zhen-heng. Moreover, in light of the taste of appreciation of literati of the Song Dynasty(宋代), which is a sample of literati spirit, Gang Hui-an inherited the inner world of the spirit whereas Wen Zhen-heng expressed 'literati-ness' in visual images.

Functionalized graphene/epoxy composites were prepared to miprove thermal conductivities of epoxy composites and to maintain electrical insulating property. Graphene oxide (GO) was prepared using Hummers method, and then GO was reacted with aluminum isopropoxide to functionalize $Al(OH)_3$ layer onto GO surface by a simple sol-gel method (Al-GO). GO and Al-GO were characterized by X-ray photoelectron spectroscopy, field emission scanning electron microscopy and transmission electron microscopy. The analyses confirm that GO was coated with a large and dense coverage of $Al(OH)_3$. GO and Al-GO (1 and 3 wt%) were embedded in bisphenol A (DGEBA) to investigate the effects of electrical insulating property. Electrical resistivity showed that Al-GO had better insulating property than GO. Further, the thermal conductivity of GO and Al-GO/epoxy composites was higher than that of neat epoxy resins. In particular, the thermal conductivity of Al-GO/bisphenol F (DGEBF) improved by 23.3% and Al-GO/DGEBA enhanced by 21.8% compared with pure epoxy resins.

A kite in Japanese is the octopus. The reason is that when they saw the tail of the kite, they remembered the foot of octopus. And this kinds of associative action is called a mitate(見立て) in Japanese. Mitate is similar to metaphor, but these two concepts are somewhat different in causing laugh. Korean and Chinese comedic story's metaphor cause laugh by similarity of two things, but Japanese comedic story's mitate cause laugh by dissimilarity of two things. Chinese and Korean comedic stories focus on 90%'s similarity of two things, but Japanese comedic stories focus on 10%'s dissimilarity of two things. So, in this paper, I tried to consider the mitate of comedic stories of East Asia, and I found that there are the following three features. First, we can see the tendency of Chinese and Korean comedic stories's mitate concern on the human body's physical weakness. But, Japanese comedic stories subject to not the human body's physical weakness but the human's professional or identification temperament. Second, East Asian's comedic stories mitate which related character and word play came from the method of decomposition of Chinese characters, for that area's people have used Chinese characters for a long time. However, there are different cases in Japanese comedic story's Chinese characters mitate, where that characters mitate is combined with two different type's characters, for example, to associate one Chinese character and another Japanese characters, hiragana or katakana. Third, there are next type's mitate which came from misunderstanding of Chinese characters, it can be seen in Chinese and Korean comedic stories. Perhaps, this pattern related with Chinese three syllable's character pattern, which is a Chinese traditional word and character play.
