1. To define 'Korean medicine industry' through study on existing medicine related industries, Korean medicine industry means all industrial activities related to Korean medicine. It covers material resources such as herbs and products made with herbs, medical instruments, Korean medical service and related information service based on Korean medicine theories. 2. According to Korea National Statistical Office standard industrial branch, Korean medicine industry was classified as a large branch. There were industries such as agriculture, food and beverage manufacture, publishing, copy of prints and record media, manufacture of compound and chemical products, medical service, manufacture of precise optical instruments, wholesale trade and product mediation, retail trade, restaurant, research and development, education service, health preservation service, entertainment, culture and sports industry related to the Korean medicine industry. 3. If we classify this according to the industry branch of English economists Clark, Colin Grant, herb cultivating industry will be classified as primary industry, manufacture of foot and beverage related to Korean medicine, secondary industry and wholesale and retail sales of herb, research and development, education, health preservation, social welfare, tertiary industries.

Stabilized biocompatible superparamagnetic iron oxide nanoparticles (SPIONs) were prepared by controlled coprecipitation method for hyperthermia application. ESR measurements determined that all of the interactions in the individual SPIONs (1 nm and 11 nm) were antiferromagnetic in nature because the ions contributed to the magnetization with a range of magnetic moments. In-situ monitoring of the temperature increment was performed, showing that the microwave absorption rate of the SPIONs was dispersed in an appropriate host media (polar or non-polar solvents) during microwave irradiation. Microwave absorption energy rates and heat loss of SPIONs in solvent were calculated by non-linear data fitting with an energy balance equation. The microwave absorption rates of SPIONs dispersed in solvent linearly increases when the concentration of SPIONs increases, implying that the microwave absorption rate can be tunable by changing the concentration of SPIONs.

We improved a visualization system for a player's sequential forms called‘Multi-Motion’which has ever been used in NHK live broadcasting. It is to extract only the player's forms from background, and overlap them into one frame sequentially after fast performance for a vault game of gymnastics. It helps TV viewers understand the player's performing forms easily. We increased the performance of Multi-Motion by shortening the distance between the current frame and the reference frame, and the synthesis of the reference frame.

The purposes of this study were to analyze the types of leisure activities and level of leisure satisfaction with practice of a five-day workweek, and examined the relationship between leisure satisfaction and job satisfaction. The data were based on the questionnaire with 264 working employee residing in Seoul. The results indicated that the most frequently participating activities were sports, use of media, loaming activities in order. And there were no significant differences in types of leisure activities between 5 day working employees and 6 day working employees. Secondly, general level of leisure satisfaction was the highest when participating religious activities. Thirdly, it was found that only social satisfaction was positively related to job satisfaction, and social satisfaction influenced job satisfaction. Further discussions and implications were discussed.

Personal media centered on blogs, Twitter, and Facebook has opened up a personal broadcasting area while meeting platforms such as YouTube and Africa TV. Due to the many advantages and disadvantages of personal broadcasting, a study on it was necessary and statistical survey was conducted. The study conducted opinion survey of 118 university students on personal broadcasting. As a result, we are getting news using smartphones and mainly watching videos through YouTube, and watching videos type in the order of games, music videos and sports. Satisfaction rate of video was 72.4%, 80.2% of survey did not use paid services, experiences about personal broadcasting was 96.6% and 90.5% of survey the prospect of person broadcasting of the opinion that "it will be expanded". The first thing we want to be improved in personal broadcasting is the prevention of abusive language and hate speech. Second, we were reluctant to sensational content. Third, the survey results are the improvement of excessive advertising.

We compare Over-the-Tops (OTTs), Netflix and Amazon Prime Video (APV) with five success factors of innovation. Firstly, Netflix offers better personalized service than APV, because APV has collaborative filtering algorithms to recommend safe bets, not the customers really want. Secondly, APV' user interface is undercooked to lock the members in, even if it has more content and better price offer than Netflix retaining its loyal customers despite the price increase. Thirdly, Netflix has simple subscription model with three tiering, but APV has complicated pricing model having annual and monthly, APV and Prime Video (AV) app, Amazon subscription and extra payment of Amazon Prime Channels (APCs). Fourthly, Amazon has fewer partnership than Netflix especially when it comes to local TV series. Instead, Amazon has live TV channel collaboration including sports content. Lastly, both have strategic and operational agility in their organization well.

In this paper, we propose a motion recognition system for identification and interaction with simulator used in the realistic biathlon simulator. The proposed system tried to improve the motions data which is obstructed by the obstacles or overlapping joints and the motion due to the fast motion in the process of recognizing the various motion patterns in the biathlon. In this paper, we constructed a multi-camera motion recognition system based on IoT devices, and then we applied a skeletal area interpolation method for normal motion identification. We designed a system that can increase the recognition rate of motion from the biathlon. The proposed system can be applied to the analysis of snow sports motion and it will be used to develop realistic biathlon simulator system.

Purpose: This study aims to analyze the management environment provincial and municipal professional soccer teams based on financial statements at a time when strengthening the financial soundness of domestic professional soccer teams is emphasized. Research design, data, and methodology: This study analyzed the financial statements (2018-2020) of the six teams of the provincial and municipal professional soccer teams whose financial statements were disclosed. The statements includes indicators of growth, profit and stability, which represents the main business performance of the entity. Results: As a result of the study, First, in terms of sales growth, sales in 2020 fell sharply year-on-year due to the impact of Covid-19. Second, the increase in sales through the import of player transfer fees had a positive impact on the growth of the business performance of the provincial and municipal professional soccer teams. Third, the profitability of the provincial and municipal professional soccer team is still low. Fourth, the debt ratio of the provincial and municipal professional soccer team was high, indicating that stability was serious. Conclusions: In order to increase sales, various strategies and measures are needed to overcome external factors such as media content products and non-face-to-face content strategies. The provincial and municipal professional soccer team, which has weak self-sustaining operations, needs to generate more profits through transferring players as a new management (profit) model, and first of all, a long-term strategy is needed to secure financial stability by improving the club's profitability.
