The size of the domestic art market has increased 21.9% over the past five years as of 2018 to KRW 448.2 billion and the number of transactions has also increased 31.6% to 39,367 points maintaining growth for the fifth consecutive year. Art distribution platforms are diversifying from galleries and auction-style offline to online auctions. The art market consists of three areas: production (creation), distribution (trade), and consumption (buying) of works and as the perception of artistic value as well as economic value spreads interest is also increasing as a means of investment. Consumers who purchase works and think of them as a means of investment technology have an increased need for objective information about their works, but there is a limit to collecting and analyzing objective and reliable statistics because information provision in the art market distribution area is closed and unbalanced. This paper identifies objective and reliable art distribution status and status through big data collection and structured and unstructured data analysis on art market distribution areas. Through this, we want to implement a system that can objectively provide analysis of authors in the current market. This study collected author information from art distribution sites and calculated the frequency of associated words by writer by collecting and analyzing the author's articles from Maeil Business, a daily newspaper. It aims to provide consumers with objective and reliable information.

본 연구는 MRI 검사를 받은 환자를 대상으로 영상매체(Visual equipment & Audio system)를 이용하여 영상물을 제공함으로서 불안과 불편감에 대한 효과에 대해 규명함으로써 MRI 검사로 인한 심리적, 정신적 불안과 불편 감을 감소시킬 수 있는 대체요법을 제공하기 위하여 본 연구를 시도하였다. 연구대상은 대전광역시에 위치한 K 대학병원에서 MRI 검사를 받은 환자 중 영상물을 제공받은 실험군 30명과 영상물을 제공받지 않은 대조군 30명을 대상하였다. 연구의 도구는 Spielberger의 기질불안 도구와 Cline, Herman, Shaw와 Morton이 고안한 불안점수 도구인 시각적 상사척도(VAS)를 이용하였고, 영상물을 제공하여 두 군 간의 활력징후를 측정하였고 불편감은 대상자의 주관적 불편감(어지러움, 공포감. 긴장감)점수와 객관적 불편감 행동 점수를 사용하였다. 자료 분석 방법은 SPSS12K for Windows program을 이용하였으며, 두 군의 일반적 특성 및 수술에 관련된 특성의 동질성 검증은 $\chi^2$ 검정, 가설검증은 t-test로 분석하였다. 연구결과를 요약해 보면 영상매체(Visual equipment & Audio system)를 이용하여 영상물(영화, 애니메이션)을 제공하면서 MRI 검사를 진행했을 경우 검사 대상자의 혈압 및 객관적 불편감에서는 유의한 영향을 미치지 못했으나 불안과 활력징후의 하나인 맥박의 감소, 또한 주관적 불편감이 감소됨을 알 수 있었다. 따라서 환자의 심리적인 긴장감을 완화시키며 안정감을 느끼게 하는데 효과적인 대체요법이 될 수 있을 것으로 사료 된다.

In this paper, correlation analysis was performed between questionnaire and machine learning based aggressive tendency measurements. this study is part of a aggressive driver detection using machine learning and questionnaire. To collect two types tendency from questionnaire and measurements system, we constructed experiments environments and acquired the data from 30 drivers. In experiment, the machine learning based aggressive tendency measurements system was designed using a driver behavior detection model. And the model was constructed using accelerate and brake position data and hidden markov model method through supervised learning. We performed a correlation analysis between two types tendency using Pearson method. The result was represented to high correlation. The results will be utilize for fusing questionnaire and machine learning. Furthermore, It is verified that the machine learning based aggressive tendency is unique to each driver. The aggressive tendency of driver will be utilized as measurements for advanced driver assistance system such as attention assist, driver identification and anti-theft system.

The 'Joongsancheung(JSC)', a unique term for the middle class in Korea, is defined as a stratum sharing common lifestyles and a certain level of life chances. It involves non-economic factors such as life chance, educational attainment, occupational groups as well as economic factor. Such objective measures as the occupational status of the main breadwinner, family income, and the educational level of respondent, and subjective measures of class identification are used for the operational definition of the JSC. Data from a national survey of 1,515 respondents is analyzed to investigate the change of the JSC in size and the major determinants of class identification. The results show that while there is no strong evidence of any significant change of the JSC by the objective measures during the recent decade, there seems to be a slight decrease in the subjective class identification. In addition, binary logistical regression analysis reveals that self-identification of JSC is heavily influenced by house ownership, along with subjective evaluation of one's own income and property ownership. This study demonstrates that the apparent class polarization in Korean society reflects not so much objective conditions but subjective perception of respondent of his or her circumstance. It is suggested that problems of housing and relative derivation people have as regards income and property should be resolved to alleviate such class polarization in Korean society.

The purpose of this study is to analyze physical properties of foreign famous worsted fabrics to realize improvements in qualities of the domestic men's worsted fabrics and to make an comparison between foreign worsted fabrics and domestic ones. For this purpose, this study carries out both objective and subjective fabric hand measurements using KES-FB system and Blind field test, to evaluate physical properties of worsted fabrics and finally is aiming to make an comparison between the results from the two measurements for enhancing the quality of the domestic worsted fabrics using the 14 specimens of 7 types as worsted fabrics manufactured in Italy, UK and Korea.

The purpose of this study is to find the railroad work characteristics that influence stress of workers in the field of Railroad electricity including railroad signaling. After a self-administered questionnaire survey was conducted from Feb. 13 to Mar. 10 of the year 2017, 445 questionnaire copies were analyzed. Objective work characteristics include total working period, current workplace, work type, train service count, train line type, a type of train in charge, failure/accident participation count, work on holidays, and work hours. Subjective work characteristics include work life satisfaction and subjective work intensity. According to bivariate analysis, stress was different depending on all railroad work characteristics. According to multivariate analysis, total working period, train service count, a type of train in charge, work on holidays, work life satisfaction, and subjective work intensity were found to be influential factors. The moderating effect of subjective work characteristics was not found in the relation between objective work characteristics and stress. Therefore, it is necessary for companies to pay attention to the influential factors on stress and manage stress.

This study was conducted to suggest a method to determine weighting values of each parameter of the RMR system considered with geologic characteristics of a study area. This study reviewed the weighting values of the RMR system for the Cretaceous sedimentary rocks distributed in Ulsan area. Based on the data of field survey at the study area, a multiple regression analysis was used to set up an optimal weighting values of the RMR parameters. For the multiple regression analysis, each parameter of the RMR and the slope gradient were regarded as the independent variable and the dependent variable, respectively. The analysis result suggested a modified weighting values of the RMR parameters as follows; 30 for the intact strength of rock; 18 for RQD; 8 for spacing of discontinuities; 32 for the condition of discontinuities; and 12 for ground water.
