Objectives : This research is aimed to consider the arranging process of the expertise on acupuncture & moxibustion in the corrective process of "Uibangyuchi" by studying the relationship between "Uibangyuchi" and "Compilation of Chimgutaekil". Methods : This researcher scrutinized the compilation & corrective process of "Uibangyuchi" through royal family records and considered the relationship between "Compilation of Chimgutaekil" and "Uibangyuchi" from the historial viewpoint. Results and Conclusions : 1. In the corrective process of "Uibangyuchi", the specialized knowledge of acupuncture & moxibustion were erased. 2. The contents related to "Chimgutaekil" among the erased contents are included in "Compilation of Chimgutaekil". 3. The method of arranging the knowledge in "Compilation of Chimgutaekil" coincides with that of "Uibangyuchi", which showes this book has a deep association with "Uibangyuchi" in the aspect of the period, organization of authors, and arrangement form. 4. The "Chimgutaekil"(Pick-a-date Method) is of no big consequence in the science of acupuncture & moxibustion but considers the example of medical procedures in the royal family of the Chosun Dynasty : the "Chimgutaekil" was the operation to be done at the very first beginning in time of the medical procedures using acupuncture & moxibustion. 5. Through such historical facts, the conclusion was made that the reason why specialized knowledge of acupuncture & moxibustion of specialty book was deleted in the compilatory process of "Uibangyuchi" is that its writing staff decided to compile these separately, thereby hurriedly publishing "Compilation of Chimgutaekil" as an example.

As the supply of xEV in Korea is rapidly increasing, the amount of waste batteries is expected to increase rapidly, but the current recycling system for waste xEV batteries is very insufficient. In order to properly utilize the xEV reusable battery module, it is essential to classify it into a type that has similar discharge characteristics to the current state of health(SOH), which is the discharge capacity of the battery. This paper proposes a system that can minimize the exchange of energy with the KEPCO system by using the charging/discharging method by circulating power between batteries in order to minimize the power consumption when charging and discharging waste batteries. In the proposed system, a function to measure parameters during the charging/discharging test of the waste battery was implemented to build a customized big date for the test waste battery. In addition, the dynamic characteristics of the proposed circuit were analyzed using PSIM, which is useful for power electronics analysis, and the validity of the proposed circuit was verified through experiments.

The purpose of this research was to investigate the transition of the concept and meaning of "bulgogi". "Bulgogi" is a representative Korean food and is also a global menu item. The first dictionary that presented the word "bulgogi" was the Keunsajeon (big dictionary). The results of an analysis of 17 dictionaries published in the last 60 years showed the immutable definition of "neobiani" as seasoned and broiled beef. In contrast, "bulgogi" has been termed differently, from "simply grilled meat of an animal" to the same meaning as that of "neobiani". Furthermore, to define the difference between common grilled meat in modern versus present time, a review of 26 cookery books from Sieuijeanseo, written in late 1800, to The Taste of Korea, written in 1987, were selected and examined. To date, the first appearance of the word "bulgogi" mentioned in a cook book was in Practice in Higher Cuisine, which was written by Shin- young Bang in 1958. The book states that "bulgogi" is the second name or the vulgar designation of "neobiani".

In the era of Big Data, humanity is facing a huge overflow of information. To overcome such an obstacle, many new cutting-edge technologies are being introduced. The movie recommendation system is also one such technology. To date, many theoretical and practical kinds of research have been conducted. Our research also focuses on the movie recommendation system by implementing methods from Social Network Analysis(SNA) and Parallel Programming. We applied the Girvan-Newman algorithm to detect communities of users, and a future package to perform the parallelization. This approach not only tries to improve the accuracy of the system but also accelerates the execution time. To do our experiment, we used the MovieLense Dataset.

Objectives : This research aims to investigate the consumer's interest in the Korean Medicine (KM) industry by using Google-trends and Naver-Data lab. A quick and uncomplicated way for those who are already involved with KM industry but do not have expertise in utilizing Big-data searches, is introduced. Methods : 'Direct keyword' was set by FGI (Focus Group Interview) and 'Detailed keyword' was set by using relevant word search and autocomplete search functions in the search engine. By inquiring Naver-Data lab, keyword search volumes are compared by age and sex, date range, and originating region of the researcher. It is possible to determine whether the data is reliable or authentic through examining the associated query. Selected direct keywords used through FGI (Focus Group Interview) were 'Acupuncture', 'Herbal Medicine', 'Cupping', 'Musculoskeletal Disease', 'Diet', and 'Stemina'. Based on these keywords, the following results were derived from the keyword analysis. Results : From August 2016, there was a noticeable surge of interest in men's 'Cupping'. The search for 'Diet' increased in the second quarter of 2016 from all ages. The search volume of 'Stemna' for individuals in their 20s is higher than that of those in their 30s or 40s'. Researchers from the region of Chungcheongbuk-do had a higher level of interest in analgesics and less interest in Korean Medicine. There is a greater interest in the KM market from European countries and America, than from Korea, China, and other Asian countries. Discussion : Despite the limitations of the research, it is meaningful to introduce a quick and easy data search method to compare information by age, sex, and region. Conclusion : The future of research into Korea Medicine and this market is confirmed by our data results which indicate interest from Europe, the United States, and other western countries, but less interest from Korea, China and other Asian countries.
