배터리 기술 고도화 및 기술표준 강화에 따라 완성차 제조사와 배터리 업계간 활발한 협업이이어질 전망이다. 또한 기존 배터리 제조사들이 활발한 증설 및 밸류 체인 확장을 통한 기술가격 경쟁력 격차 유지에 적극적으로 나서고 있어, 향후 시장 주도권 경쟁이 가속화될 것으로 전망된다. 배터리의 온도 상승은 배터리 효율을 낮추는 원인이며, 배터리 온도 제어가 전기자동차 차량의 전체 성능 향상에 중요한 부분이라고 할 수 있다. 본 연구는 실제 Battery Pack 실험 전 열유동해석을 통해 배터리온도 상승추이 및 냉각효율 검증을 진행하는 과정에서 발생하는 과도한 시간 소요를 줄이기 위해 Machine Learning 을 활용하여 검증 효율 및 설계 효율을 높이는데 그 목적이 있으며, CFD를 활용한 배터리 효율 최적화 설계를 하는 기존 모델 대비 30%~50%정도의 성능향상을 예측할 수 있다.

This article examines the history of the in - house subcontracting and the stabilization of labor - management relations in the steel industry in Japan. The ratio of in-house subcontract workers among steel workers has increased steadily until the mid-2000s, and about 70% in case of the largest company. In-house subcontracting was used as a strategy of the company to increase the quantity flexibility of employment and to save labor costs. The in-house subcontracting company needed company-specialized skills, and the internal labor market was formed because the rate of full-time workers was high and the turnover rate was low. The in-house subcontractor introduced long-term business relationship with the steel factory by introducing the equipment and materials necessary for the performance of the work, and the factory implemented the productivity improvement policy of the in-house subcontractor, and the win-win relationship between the factory and in-house subcontractor was developed. The trade union did not oppose the idea that the expansion of in-house subcontracting contributed to corporate profits, the stability of employment of the members and maintenance of their working conditions. Since 2000, the steel factory has pursued the transformation of in - house subcontractors into subsidiaries, which has been supported by capital relations. By the way, since the mid-2000s, there has been an increase in the number of regular workers' employment. The major factors are as follows: more strengthened compliance with laws and regulations, the higher quality request of customers, stricter keeping of deadlines, and problem in recruiting of workers at in-house subcontract companies. The wage gap between the factory and in - house subcontracting was less at company B than at company S, and the wage level of in - house subcontracting was about 90% of the factory at company B. The relatively small gap at company B seems to be due to the union's movement of narrowing the gap, low market dominance and unfavorable labor market. The internal labor market has been formed in the in-house subcontracting, and the wage gap is not large, and the possibility of labor disputes is low. Industrial relations are stable in the in-house subcontract company as well as the factory. The stabilization of labor-management relations in the steel industry in Korea is required to reduce the wage gap between the factory and in-house subcontract enterprises by raising productivity and expanding the internal labor market at in-house subcontract enterprises.

The purpose of this study is to examine the factors affecting the intention of smart device internet usage from the perspective of lifelong learning of elderly people. Survey was conducted for understanding the factors affecting the internet usage intention of smart devices with 150 elderly people who visited the Gwangju Senior Technology Center (GSTC). The empirical results show that the perceived economic value and practical value of the elderly have a significant effect on the intention of utilizing the Internet of Smart Device. Although the moderating effect of the individual innovation of the elderly is not significant, Participation in social activities significantly moderated the relationship between perceived value and intention to use internet. In addition, the elderly expected that the quality of life would be improved via the use of smart devices.

The purpose of this study is to induce the activation of public libraries in community through make use of public libraries as a plan for accomplishing regional informatization which based on regionalization and informatization. To acquire the twin goal of regional informatization and activation of public libraries, I propose a strategic plan which makes use of regional public libraries as an infrastructure of educating informatization and community-network concept. Especially those plans would cover recent background issues of super-national interest in rural welfare & development venture.

건축, 구조, 기계, 전기, 토목, 조경 등 IT와 관련된 다양한 산업 분야에서는 각 산업의 기획, 생산, 운영등 단계별로 다양한 주제를 가지고 논의 및 시뮬레이션을 통하여 각 업체별로 의사를 개진해 나간다. 그러나 업종별 공정에 맞는 커뮤니케이션이 원활히 이루어져 나가기는 힘들다. 이러한 이유 중 가장 큰 부분은 데이터들이 다양한 뷰어(Viewer)들을 통하여 2차원적으로 보는 부분이 큰 비중을 차지하는 것에 비해 실제 결과물은 3차원적으로 다루어지고 있기 때문에 과정과 결과간의 격차로 인하여 벌어지는 문제가 크다. 각각 다양한 분야에서 생산되는 데이터들의 불확실성, 표현의 애매모호함으로 인하여, 이전 공정 단계에서 받은 데이터들을 현재의 공정 단계에 맞는 데이터로 변환되는 과정이 생긴다. 불필요한 과정들이 반복되는 사이 모든 공정이 지연되고, 많은 예산이 소모되는 등 많은 문제들이 발생되고 있다. 따라서 본 연구에서는 다채널을 활용한 VR 시뮬레이터로 몰입감을 높이고, 실제와 유사한 실감형 시뮬레이션으로 엔지니어링 VR 시뮬레이션이 가능함을 알 수 있었다. 향후에는 사용자의 용도와 목적에 따라 다양한 분야에서 활용의 범위가 넓을 것으로 기대되며, 많은 공간과 비용이 드는 현재의 다채널 시뮬레이터 형태를 보다 공간과 비용의 소모가 적고, 이동성을 갖춘 이동형 다채널 VR 시뮬레이터에 관한 연구가 필요하다.

There are concerns that the recent surge in multicultural families and the continuation of non-face-to-face education, such as remote classes caused by COVID-19, are causing educational gaps among lower grades in elementary school. In particular, the importance of reading, writing and listening to our language should be established in lower grades of elementary school. Therefore, the research has recently developed contents that can enhance understanding by utilizing highly interested artificial intelligence tools and provide interesting Korean language education through play. In the future, there will be various attempts for artificial intelligence tools to be used in lower-grade elementary school education.

The purpose of this research is to examine the difference between the Importance-Performance of parents' perception in an Information and Communication Technology(ICT) environment for young children. The researchers reviewed the literature looking at activating factors in an ICT setting such as young children, teachers, parents, physical environment, social support and administrative supports. As a result of Importance-Performance Analysis(IPA) matrix participating with 459 parents, it was noted that the young children, physical environment and administrative support factors are the most crucial in activating ICT environment at home. This implies that fostering individual children's ICT ability is required as soon as possible to access the right information and to work on line certainly for their future.

This article assesses and examines democratic potentials of the Internet for U.S. citizens' political participation. The empirical analysis on the data from Pew Research Center's questionnaire survey focuses on four different political activities in both online and offline modes: casual political talk, contact with a government official, petition, and political contribution. The study answers two research inquiries: 1) How does the Internet influence the established patterns of political participation?; and 2) How does the Internet influence the demographic distribution of participatory inequality? Firstly, the Internet, by providing existing participants with additional tools for participation, reinforces conventional participation, rather than mobilizing new participation in politics. Secondly, the online patterns of the participation divide with respect to demographic characteristics imitate the traditional patterns of inequality and disproportionate representativeness in political participation. The Internet is still not a predominant medium for political activities. Citizens' utilization of its transformative and mobilizing potentials remains limited.
