본 연구의 목적은 유럽연합에서 개발한 세계 대학 평가시스템 '유-멀티랭크(U-Multirank)'를 통해 대학의 실제 경쟁력과 질적 수준을 재검토해야 할 필요성 그리고 세계 대학 순위평가 시스템이라는 개념을 재정립해야 필요성을 역설하는 데 있다. 지금까지 널리 활용되고 있는 THE나 ARWU와 같은 세계 대학 순위평가 시스템은 연구중심 종합대학에 초점을 맞추어 정량화된 평가 방식을 취해왔다. 그러나 이러한 평가 방식은 세계 고등교육 분야에서 대학과 전공 간의 서열화를 조장하는 동시에 소규모 지방대학이나 유사 고등교육기관을 소외시키는 결과를 낳았다. 더구나 대학 순위평가제의 본래 취지가 잠재적 대학 편 입학자들에게 실질적이고 포괄적인 정보를 제공함으로써 그들 개개인의 교육 이상과 요구에 부합하는 고등교육기관을 선택할 수 있도록 돕는데 있다는 점을 도외시한채, 기존의 정량화된 평가 방식과 순위발표는 결코 도표 위의 수치로 환원될 수 없는 복잡다양한 교육현실을 축소시키는 문제마저 초래하였다. 유럽연합 교육위원회는 세계 대학 평가시스템의 이러한 결함을 보완하고 유럽 사회에 필요한 고등인재를 길러내기 위해 2009년부터 2011년까지 타당성 조사와 파일럿 테스트를 거쳐 '유-멀티랭크'라는 새로운 세계 대학 평가시스템을 개발하였다. THE나 ARWU 등과 차별화되는 유-멀티랭크의 특징은 사용자 중심성, 다차원성, 개별성이라는 원칙 아래 대학에 관한 질적 평가 방식을 취한다는 데 있다. 이 시스템은 모바일 운영체계를 기반으로 설계되어 디지털 글로벌 시대에 최적화된 세계 대학 평가시스템의 본보기를 제시할 뿐 아니라, 사용자의 접근성과 참여폭을 확장시킴으로써 시스템 자체의 무한한 자기검증과 진화 가능성까지 열어놓고 있다. 이는 대학 평가시스템의 투명성 확보와 관련해 대단히 중요한 장점이다. 무엇보다 유-멀티랭크의 사용자 중심 모바일 운영체계는 미국대학 중심의 기존 세계 대학리그에 국내 외의 다양한 대학들을 노출시킴으로써 공정한 질적 경쟁의 장을 마련해준다는 점에서 우리 대학들의 글로벌 경쟁력 강화를 위해서도 희망을 걸만한 대안이라 생각된다. 유-멀티랭크를 통한 세계 대학 평가시스템의 재개념화 가능성을 타진하기 위해 본 연구는 Edgar Morin의 복잡성 사고 이론과 Karl Popper의 과학철학에 기댄 인식론적 접근을 시도하고 있다.

This study assesses the growth and distribution of research journals indexed in Scopus from 2000 through 2019, using SCImago data for journal and country ranking. A total of 15,484 journals were indexed in Scopus up till 1999, and from 2000 to 2019, 11,037 journals were indexed in Scopus at an average of 581.85 journals per year at an average annual corresponding growth of 2.74%. Of the total journals indexed in Scopus, 41.61% were indexed during the last two decades. Europe is the leading continent publishing nearly 60% of the total world journals, while Africa publishes around 1% of journals, the lowest among all the continents. The United Kingdom, United States (US), China, Brazil, Australia, and Egypt are the leading countries publishing the maximum number of journals from their respective continents. Of the total journals indexed across the world, nearly one-fourth (6,425, 24.23%) are published in the US. Still more, of the 109 journal publishing countries across the world, nearly 90% of journals are published in twenty leading journal publishing countries. Among the 27 major Scopus recognized subject disciplines, the majority (1,606, 6.06%) of journals are published in the field of medicine. The growth of research journals and the growth of research results has moved at a uniform pace, and any asymmetry between the two is bound to result either in the introduction of predatory and dubious journals or in the production of sub-standard research results.

South Korea's per capita alcohol consumption ranking is 14th in the world, but it ranks first in the world for binge drinking. In society, dining and dining culture is developed, which leads to drinking. He often puts his hands on the wheel in a relaxed way after drinking. To prevent this situation from happening in advance, a Bluetooth module is installed in the aduino circuit to transmit the measured alcohol level to the smartphone and measure the blood alcohol level.

Objectives: This study aimed to evaluate the effect of aging on the marginal quality of glass hybrid (GH) material used to elevate dentin gingival margins, and to analyze the consistency of the results obtained by 3 in vitro methods. Materials and Methods: Ten teeth received compound class II cavities with subgingival margins. The dentin gingival margins were elevated with GH, followed by resin composite. The GH/gingival dentin interfaces were examined through digital microscopy, scanning electron microscopy (SEM) using resin replicas, and according to the World Dental Federation (FDI) criteria. After initial evaluations, all teeth were subjected to 10,000 thermal cycles, followed by repeating the same marginal evaluations and energy dispersive spectroscopy (EDS) analysis for the interfacial zone of 2 specimens. Marginal quality was expressed as the percentage of continuous margin at ×200 for microscopic techniques and as the frequency of each score for FDI ranking. Data were analyzed using the paired sample t-test, Wilcoxon signed-rank test, and Pearson and Spearmen correlation coefficients. Results: None of the testing techniques proved the significance of the aging factor. Moderate and strong significant correlations were found between the testing techniques. The EDS results suggested the presence of an ion-exchange layer along the GH/gingival dentin interface of aged specimens. Conclusions: The marginal quality of the GH/dentin gingival interface defied aging by thermocycling. The replica SEM and FDI ranking results had stronger correlations with each other than either showed with the digital microscopy results.

This paper aims to propose a Comprehensive Decision Support Model to evaluate retail companies' financial performance traded on the Vietnam Stock Exchange Market. The financial performance has been examined in terms of the valuations ratios, profitability ratios, growth rates, liquidity ratios, efficiency ratios, and leverage ratios. The data of twelve companies from the first quarter to the fourth quarter of 2019 and the first quarter of 2020 were employed. The weights of 18 chosen financial ratios are calculated by using the Standard Deviation method (SD). Grey Relational Analysis technique was applied to obtain the final ranking of each company in each quarter. The results showed that leverage ratios have the most significant impact on the retail companies' financial performance and gives some long-term investment recommendations for stakeholders and indicated that the Taseco Air Services Joint Stock Company (AST), Mobile World Investment Corporation (MWG), and Cam Ranh International Airport Services Joint Stock Company (CIA) are three of the top efficient companies. The three of the worst companies are Viglacera Corporation (VGC), Saigon General Service Corporation (SVC), and HocMon Trade Joint Stock Company (HTC). Furthermore, this study suggests that the GRA model could be implemented effectively to ranking companies of other industries in the future research.

Purpose - This study analyzes economic relations and mutual influence in the global equipment manufacturing industry (EMI) and China's influence. Research design, data, and methodology - Data were collected from the World Input-Output Database (WIOT), looking at 16 countries. The sample time period was 2002-2011. Influence and motivation coefficients were calculated. Results - 1) China's EMI showed a very strong influence coefficient, even surpassing world industrial powers like Japan, the USA, Germany, and Korea. 2) As for influence on added-value, China's EMI motivation coefficient was ranked third in 2011, which meant it had a negligible effect on added-value. 3) From 2002 to 2011, both the influence and motivation coefficients of China's EMI rose. Conclusions - China's EMI has strong influence and motivation coefficients. It has a significant impact on the world EMI, especially on the total output of the global EMI. Additionally, during 2002 to 2011, the ranking of China's EMI motivation coefficient improved year over year, and its economic efficiency obviously improved. By 2011, China's EMI's international influence was second only to the US and Japan.

While studies have viewed the effect of Chinese talent-attracting programs launched by government since reform and open door policy, little of them has assessed these programs empirically and pertinently. This article intends to assess an important program - the Thousand Youth Talents Program (TYTP). Frist, this paper proposed a transnational migration matrix of the academics to clarify the dynamic mechanism of academic brain gain at the high end. Then, the Kaplan-Meier analysis and Cox regression model are used to empirically analyze the policy effect of TYTP. The results show that, academic ability have double edged impacts on brain gain at the high end, some scholars whose last employer's academic ranking is world's Top100 have stronger willing to return, and the negative effect of academic ranking decreases with time passing; while scholars with a tenure-track position, a tenure position or a permanent position tend to stay overseas, and the hazard rate of staying increases with age. The older scholars have more intentions to go back China, while gender was not a significant factor influencing academic return at the high end. That is, the talent-attracting programs has partly succeeded in bringing back the academics at the high end.

The number of interconnected real-world devices such as sensors, actuators, and physical devices has increased with the advancement of technology. Due to this advancement, users face difficulties searching for the location of these devices, and the central issue is the findability of Things. In the WoT environment, keyword-based and geospatial searching approaches are used to locate these devices anywhere and on the web interface. A few static methods of indexing and ranking are discussed in the literature, but they are not suitable for finding devices dynamically. The authors have proposed a mechanism for dynamic and efficient searching of the devices in this paper. Indexing and ranking approaches can improve dynamic searching in different ways. The present paper has focused on indexing for improving dynamic searching and has indexed the Things Description in Solr. This paper presents the Things Description according to the model of W3C JSON-LD along with the open-access APIs. Search efficiency can be analyzed with query response timings, and the accuracy of response timings is critical for search results. Therefore, in this paper, the authors have evaluated their approach by analyzing the search query response timings and the accuracy of their search results. This study utilized different indexing approaches such as key-words-based, spatial, and hybrid. Results indicate that response time and accuracy are better with the hybrid approach than with keyword-based and spatial indexing approaches.

Many parts of life have been changed due to the unprecedented coronavirus outbreak, and Noncontact has now become a general culture of society around the world. Also, many years later, after the Fourth Industrial Revolution, it is now deeply embedded in the human lifestyle. The purpose of this paper's research is to investigate the metaverse perception before and after Corona. It was confirmed that the number of metaverse, the central keyword, was 70971 before Corona, but 261767 after Corona, which was more than three times the frequency. In addition, it was confirmed that the number of COVID-19, the reference point of this study, increased significantly to 1,9236 during the pre-COVID-19 period. Through this, it can be inferred that the metaverse accelerated and developed significantly after the corona. Metaverse about Keywords such as cryptocurrency, cryptocurrency, coin, and exchange appeared before Corona, and the word frequency ranking for blockchain, which is an underlying technology, was high, but after Corona, the word frequency ranking fell significantly as mentioned above. As such, it was confirmed that keywords for metaverse were changing before and after Corona, and as such, Consumers' perceptions were also changing.

The problem Japanese universities face is exactly the same as that of German universities: no international recognition in world rankings of universities despite their high levels of postwar economic and technological developments. This was indeed one reason why world-class Japanese firms, such as Toyota and Sony, have avoided working closely with Japanese universities for R&D partnership and new technology commercialization. To resolve this problem, the Japanese government has continuously implemented aggressive policies of the internationalization, privatization, liberalization, and privatization of universities since the onset of the economic recession in 1989 in order to revitalize the Japanese economy through radical innovation projects between universities and firms. National projects of developing medical robots for Japan's ageing society are some of the ambitious examples that emphasize feed-forward learning in innovation. However, this paper argues that none of these programs of fostering university-firm alliances toward feed-forward learning has been successful in promoting the world ranking of Japanese universities, although they showed potentials of reinforcing their conventional strength of introducing $kaizen$ through feedback learning of tacit knowledge. It is therefore argued in this paper that Japanese universities and firms should focus on feedback learning as a way to motivate firm-university R&D alliances.
