Recently, the development and marketing of fatigue-reducing seats has been active, and this product is expected to provide better rest and comfort to passengers during autonomous driving and charging of electric vehicles. The core technology of the fatigue reduction seat is the proper positioning of the upper and lower body of the human body and the development of a mechanical device to implement it. Leg rests that support below the knees were generally applied only to the rear seats, but with the expansion of the fatigue-reducing seats, they are also being applied to the driver and front passenger seats. Domestic companies have secured leg rest mechanical design capabilities, but lack the ability to determine the motor capacity that operates them. In this study, structural changes in future car seats, development trends of fatigue-reducing seats and leg rests, and evaluation methods were investigated, and finally, a model was developed to predict the load amount of the 6-section link leg rest motor.

도시철도 이용객의 증가로 수도권 일부 정거장의 경우 일일 이용객 수가 20만명 이상이며, 특히 환승통로의 극심한 혼잡상황이 반복되고 있다. 이에 본 연구에서는 LOS등급별 밀도에 따른 속도 및 보행패턴 검증을 위해 보행특성 관찰이 가능한 모션인식 카메라를 이용한 현장실험을 수행하였다. 실험장소는 도시철도 대림역으로 역사 내 환승인원이 가장 밀집한 구간을 선정하여 평일 1일간 시간대별 밀도, 속도, 시간 및 행동패턴을 측정하였다. 도시철도 면적산정 시 평균속도는 1m/s이나 실험결과 LOS D등급은 0.8m/s, E등급은 0.58m/s로 분석되었다. 도출된 결과로부터 도시철도 이용객 LOS 수준을 효과적으로 예측 및 평가하고, 정거장의 개선 또는 신설 시 경제적, 효율적 면적 산정을 위한 기초자료로 활용하고자 한다. In the case of some stations in the metropolitan area by increasing of metro passengers, it is more than 200,000 the number of daily passengers. Especially serious congestion of transfer passage is repeated. In this study, it was conducted field experiments using the motion sensing camera capable of walking characteristics observed for the verification of the walking speed and the patterns of behavior in accordance with the LOS graded density. Experiment location is a metro Daerim Station. The transfer passage in the most crowded section was selected. Hourly the density, walking speed, time and the behavior patterns were measured for one weekday. The average speed in metro area estimates is 1m/s. The results of the experiment were analyzed to LOS D in 0.8m/s and LOS E in 0.58m/s. The LOS of metro passengers were effectively predicted and evaluated from the derived results. The results of this study utilized as a basic data to calculate an appropriate area when the improvement or construction of the station.

After presenting the Fourth Industrial Revolution on the agenda at the Davos Forum in 2016, interest in the Fourth Industrial Revolution is increasing rapidly around the world. The fourth industrial revolution, an era of industrial innovation in which ICT technology is integrated with various industries, is expected to bring about a new era that humanity has not experienced. Strategic management of intellectual property (IP) is important in order to secure the leadership of the future market. In addition, there is a need to revitalize the intellectual property service industry, which is a professional service industry supporting the creation, protection and utilization of intellectual property. In this study, we propose the application method in the intellectual property consulting industry through the future new technology in order to find the countermeasure of the intellectual property consulting industry during the 4th industrial revolution era.

The purpose of this study was to classify the subtypes of aggression in children and adolescents living in foster care to confirm the characteristics of overt aggression and relational aggression. The research sample included a total number of 848 children and adolescents with psychological disorders in foster care. When exploring the differences in the mean of each subtype of aggression, the results varied according to age and gender. As a result of confirming the differences of problem behaviors according to aggressiveness in four groups, the overtly-relationally aggressive groups showed the highest score and all the problem behaviors were serious. In terms of externalizing problems, the overt aggressive groups had more problematic behavior than the general groups. In terms of internalizing problems, the relational aggression groups had higher scores than the general groups.

Recently advanced laser processing is widely introduced to improve the efficiency of micro part production and to reduce the rate of inferior goods. In this paper the trend of delamination of single layer with both thin copper and polyimide according to the variation of copper thickness was investigated using the coupled thermal-structural analysis of ANSYS. From these analyses results, some conclusions were obtained. Firstly, the maximum temperature was increasing with respect to decrease of copper thickness. Secondly the maximum strain which was in general estimation the main effect of the delamination was observed in case of the copper thickness of $5{\mu}m$. Finally the trend of the delamination was decreasing with increasing the thickness of copper layer.

South Korea has already entered the aging society, estimates that there will be a super-aged society over 60 years old population ratio of 20.8% in 2026. Developed countries and Asian countries has faced a similar problems for the aging society. The population over 60 years old, which was 6% in 1960, have increased by over 10% in 2013. As part of the measures for this problem, South Korea has already been nine years since the introduction of the retirement pension plan. But, still retirement pension plan, which the weight of the DB is enlarging and most of the assets is invested in principal-guaranteed products, do not serve as a proper retirement scheme. We can find out that there are many difference between South Korea and Major Asian Countries through comparative analysis on retirement pension plan system, history, type and operating status. This study will be presented the improvement in retirement pension plan. The finding in this paper indicate that it is necessary that introduction of mandatory retirement pension system, Minimum Sum and CPF Life plan in Singapore, establishing well diversified investment culture, changing pension provision age from 55 years old to 60 years old is necessary to consider.
