This paper presents the design of robot foot module of four-point biped walking robot and its fabrication. The foot module has four sensor units based on contact-resistance force sensor. The thin-film-type force sensor is fabricated by coating resistive ink on thin polyimide film using silk screening technique. The simple structure is devised and fabricated to assemble the thin force sensor rigidly. The unit force sensor module is evaluated by the calibration setup to obtain the characteristics of repeatability and hysteresis. The sensor module presents hysteresis error of about 5% and repeatability error of about 0.37%. The calculated zero moment point (ZMP) of the foot module is also compared with the measured position using static load of 50 N. The maximum location error of ZMP is less than 10%. The robot foot module shows the possibility of applying it to humanoid walking.

The quality of life has been improving further, with economic growth beginning in the late 20th century, improving national welfare and expanding living space. However, the rapid increase in the number of industrial complexes and the failure to take into account the living conditions in the surrounding residential areas have created a risk to the health of local residents, which has led to increased interest in air pollutants, and the growing interest in indoor air quality is also increasing as people spend more time indoors. In particular, the air pollution problem in various industrial and metropolitan areas is drawing keen attention, and among them, the air pollution in petrochemical industries is at a serious level. Among them, Volatile Organic Compounds (VOCs) are common air pollutants found in the surface atmosphere in urban areas or near industrial complexes and are known to be emitted into the atmosphere by human industrial activities and biological sources. In this study, based on the contents of the survey of residents in the Yeosu Industrial Complex and the concentration of indoor, outdoor and personal exposure, we would like to find out how personal life habits correlate with xylene and ethylbenzene among VOCs.

최근 들어 미디어 경영학의 독립과 관련된 움직임이 제시되고 있고, 미디어 경영학을 독자적인 분야로 간주하고 향후 이 분야의 진행 방향을 예의주시할 필요성이 제기된다고 본다. 미디어 경영학의 발달은 학문 자체의 동력에 근거했다기보다는 산업 분야의 확대에 기반을 두고 있다. 미디어 경영학은 20세기 중반 들어 미디어 관련 기업들의 수와 규모가 증대하면서 관심을 받기 시작했다. 본 연구에서는 미디어 경영학 연구의 현황을 분석하고 향후 방향을 검토하는 것을 목적으로 설정하였다. 이를 위해, 미디어 경영학의 현황을 탐색적 수준에서 Porter의 모형과 자원준거관점(RBV)을 활용하여 분석하였다. Recently, movements related to independence of media management have been proposed, and media management needs to be considered an independent field and the progress of this field needs to be closely watched. The development of media management is based on the expansion of industry, as is the case in the field of communication rather than on the basis of the academic engine itself. Media management began to draw attention in the mid-20th century as the number and scale of media-related enterprises grew. The purpose of this study was to analyze the status of media management research and review future directions. To this end, the status of media management was analyzed using the model of Porter and the Resource Dependent Perspective (RBV) at the Exploration level.
