I want to focus on developments in the areas of general relativity and gauge theory. The topics to be considered are the singularity theorms of Hawking and Penrose, the positivity of mass, instantons on the four-dimensional sphere, and the string picture of quantum gravity. I should mention that I will not have time do discuss either classical mechanics or symplectic structures. This is especially unfortunate, because one of the roots of differential geometry is planted firmly in mechanics, Cf. [GS]. The French geometer Elie Cartan first formulated his invariant approach to geometry in a series of papers on affine connections and general relativity, Cf. [C]. Cartan was trying to recast the Newtonian theory of gravity in the same framework as Einstein's theory. From the historical perspective it is significant that Cartan found relativity a convenient framework for his ideas. As about the same time Hermann Weyl in troduced the idea of gauge theory into geometry for purposes much different than those for which it would ultimately prove successful, Cf. [W]. Weyl wanted to unify gravity with electromagnetism and though that a conformal structure would fulfill thel task but Einstein rebutted this approach.

The present papers (I and UU) deal with the total records of Korean subterranean animals reported during the last forty years since its first one in 1938 through 1978. They have been published in 33 different articles by 29 authors from 7 different countries. They enlist 109 species in 53 families in 7 classes belonging to 3 different phyla collected from 45 caves and 9 wells around the country. Predominant are arthropods enumerating 101 species (92.7%), of which insects are represented by 37 species. The number of species reported exclusively from subterranean habitats, presumably troglobionts, amount to 60 (55%). Discussions regarding the systematic situation of each taxa in question are made and the rate of occurrences of totally subterranean animals is determined and compared by respective taxa in a few different geographic regions. Also checklists are prepared and given in systematic order, which are followed by general analysis. Some attempts are also made to give suggestions, hopefully, for the prograess and improvement of korean biospeleology. the present article, Part I, will be completed by Part II dealing with insects which sppears in the Korean Journal of Entomology Vol. 8, No. 2 of the 1978 edition.

This study aimed to identify target lexical bundles (e.g., on the other hand, at the same time) for argumentative essay writing and rank them in order of teaching priority for Japanese learners. Despite significant functional roles of lexical bundles in academic writing, the inclusion of lexical bundles in argumentative writing had been underexplored. Since argumentative writing skills help undergraduate students prepare for their academic careers (e.g., writing papers), the lexical bundles under this genre deserve more attention. This study first extracted 78 target bundles from L1 argumentative essay corpora (International Corpus Network of Asian Learners of English: ICNALE and Louvain Corpus of Native English Essays: LOCNESS). The study then classified the bundles according to their discourse functions and semantic transparency to estimate the learnability for Japanese learners in L2 compatible corpora with the ICNALE. The results showed that learners had difficulty using the bundles with referential functions (e.g., in the form of) and semantic opaqueness (e.g., when it comes to), suggesting that the bundles in these two categories should be prioritized among the 78 bundles.

The purpose of this study was to discuss the papers of social welfare field that were published in Korea, from a research methodology aspect in accordance with the meta-analysis reporting standard proposed by the United States Psychological Association. To this end, an analysis was conducted according to 5 types of conformity (title and abstract, introduction, methods, results and discussion) on the target subjects of 26 meta-analysis papers of social welfare field. The analysis results showed, first, the conformity in the title and abstract showed good results except for the suggested topics for meta-analysis methods. Second, in terms of the conformity of the introduction, the descriptions seemed to be good in a number of items. Third, for the conformity in the methods, the overall reporting standard was seen to be lacking and, in particular, the reporting standard for the coding procedure was seen as being very deficient. Fourth, the conformity in the results showed that the assessment of research quality and the magnitude of efficacy for each individual study, sample size, and the contents of the provided tables, summary of tables and graphs, including the study results, were not being properly reported. Fifth, the conformity in discussions was seen to be generally sound. Based on such results, by providing a reporting standard and perspective needed for ensuring feasibility that can be used to assess meta-analysis study materials, this study was aimed at presenting implications for the academic advancement of field of social welfare.

The purpose of this study was to analyze the research status and trends related to the industrial mathematics based on text mining techniques with a sample of 4910 papers collected in the SIAM Journal on Applied Mathematics from 1970 to 2019. The R program was used to collect titles, abstracts, and key words from the papers and to analyze topic modeling techniques based on LDA algorithm. As a result of the coherence score on the collected papers, 20 topics were determined optimally using the Gibbs sampling methods. The main results were as follows. First, studies on industrial mathematics were conducted in a variety of mathematics fields, including computational mathematics, geometry, mathematical modeling, topology, discrete mathematics, probability and statistics, with a focus on analysis and algebra. Second, 5 hot topics (mathematical biology, nonlinear partial differential equation, discrete mathematics, statistics, topology) and 1 cold topic (probability theory) were found based on time series regression analysis. Third, among the fields that were not reflected in the 2015 revised mathematics curriculum, numeral system, matrix, vector in space, and complex numbers were extracted as the contents to be covered in the high school mathematical curriculum. Finally, this study suggested strategies to activate industrial mathematics in Korea, described the study limitations, and proposed directions for future research.

Objective : Two famous medical doctors, Yoo Itae(以泰, 爾泰) and Riu Euitae(義泰), have been well known in academic world and public in Sancheong-gun. Yoo Itae is the progenitor of Majinhak which is the therapy for measles, he wrote a "Majinpyun" as the first book of therapy for measles in Chosun. Riu Euitae, meanwhile, is a fictional medical doctor and a teacher of Heo Jun who became real without confirmation of historical truths by Roh Jeongwoo who heard about a name, Yoo Itae. Roh's assertion was quoted in the report of literatures, papers, novel, and telecast without verification. His assertion is exposed in novel and media and it has seriously distorted the history. The purpose of this study is to rectify the historical distortion. Methods : Various references study was performed. Confirmed a family tree, birth and death year, birthplace, sepulture, words on a tombstone, writing, collections of works anthology and the existence of keepsake. Investigated records of royal family, Sancheong-gun papers, Sancheong Hyanggyo papers, Dongyuhagan, Chosun Hanryuseungram and the record of Sawoo Munjip(anthology). Analyzed Roh Jungwoo's conversation that tells Riu Euitae is a teacher of Heo Jun and contents of an encyclopedia. Listened to testimony of descendants and assertions of historian in rural area. Verified voice recording on books taken from at birthplace and the space of activity. Results : Yoo Itae is well shown in various records and medical writing books, whereas Riu Euitae does not. Riu Euitae is not a real person in the history. Roh Jeongwoo who asserts Riu Euitae is a teacher of Heo Jun admits his mistake. But, the encyclopedia record describing Riu Euitae is a teacher of Heo Jun, government official at Sancheong district office, historians in rural area, historians in rural area who made a family shrine, gravestone, a statue, memorial, historic site of Riu Euitae on Jinju Rui could not suggest any evidences for the existence of Riu Euitae and for record Riu Euitae is a teacher of Heo Jun. Conclusion : Riu Euitae is neither a real person in the history nor a teacher of Heo Jun. Riu Euitae came from pronunciation confusion between 'I' and 'Eui' in Kyungsang province. Riu Euitae is Yoo Itae on Geochang Yoo who was a medical doctor of King, Sukjeong and wrote medical books including , , .

Purpose - The study aims to provide the relationships between the social servicescape and customer's emotion and voluntary behaviors were investigated in this study. The social servicescape was largely divided into service employee's image and other customers (in customer's similarity, physical appearance and suitable behavior). Firstly, the relationship between service employee's image and customer's positive emotion was investigated as a specific purpose of study. Secondly, this study attempted to understand the relationship between other customers (in customer's similarity, physical appearance and suitable behavior) and customer's positive emotion. Lastly, the relationship between customer's positive emotion and customer's voluntary behavior dimension (intention to cooperate, intention to participate in and loyalty) was examined. Research design, data, & methodology - In order to prove the hypotheses in this study, the customers who have experienced family restaurants during the last two months were targeted for a survey. A total number of 300 survey papers were distributed and as a result, 248 papers could be used for analysis, except the papers with insincere answers. After the analysis of the reliability and validity of each major variable, the hypothesis was verified through the structure method by using Amos 20.0. Results - First, the results of hypothesis testing on the relationship between social servicescape and customer's positive emotion showed service employee image gives a positively meaningful impact on customer's positive emotion. Secondly, the results on the relationship between other customers and customer's positive emotion indicated that the customer's similarity and physical appearance has a positively significant impact on customer's emotion while customer's suitable behavior has not a significantly positive impact on customer's positive emotion Lastly, customer's positive emotion was shown to have a significantly positive influence on customer's voluntary behavior dimension, that is, intention to cooperate, intention to participate in and loyalty. Conclusions - This study aims to focus on and emphasize the social servicescape and its importance, which is different from the previous studies that have been focused largely on physical servicescape. Such results in this study indicated the social servicescape (service employee's image and other customers) as an important factor that affects customer's positive emotion and voluntary behavior.

Objectives: By grasping trends in research, technology, and general characteristics of learning support tools, this study was conducted to present a model for research on Korean Medicine (KM) to make use of information technology to support teaching and learning. The purpose is to improve the future clinical competence of medical personnel, which is directly linked to national health. Methods: With papers and patents published up to 2011 as the objects, 438 papers were extracted from "Web of Science" and 313 patents were extracted from the WIPS database (DB). Descriptive analysis and network analysis were conducted on the annual developments, academic journals, and research fields of the papers, patents searched were subjected to quantitative analysis per application year, nation, and technology, and an activity index (AI) was calculated. Results: First, research on medical learning support tools has continued to increase and is active in the fields of computer engineering, education research, and surgery. Second, the largest number of patent applications on medical learning support tools were made in the United States, South Korea, and Japan in this order, and the securement of remediation technology-centered patents, rather than basic/essential patents, seemed possible. Third, when the results of the analysis of research trends were comprehensively analyzed, international research on e-PBL- and medical simulation-centered medical learning support tools was seen to expand continuously to improve the clinical competence of medical personnel, which is directly linked to national health. Conclusions: The KM learning support tool model proposed in the present study is expected to be applicable to computer-based tests at KM schools and to be able to replace certain functions of national KM doctor license examinations once its problem DB, e-PBL, and TKM simulator have been constructed. This learning support tool will undergo a standardization process in the future.
