Recently, maintenance of old facilities has emerged as a major issue. In particular, the demand for road cutting and excavation is increasing due to the aging of underground facilities such as water supply, sewage and city gas. In addition, the development of eco-friendly equipment is required due to the environmental problems of noise and dust. Therefore, this study intends to analyze the performance in terms of productivity of the eco-friendly road cutter developed as part of the development of eco-friendly equipment, and to derive improvements.

The global demand for lithium-ion batteries (LIBs) has been continuously increasing since the 1990s along with the growth of the portable electronic device market. Of late, the rapid growth of the electric vehicle market has further accelerated the demand for LIBs. The demand for the LIBs is expected to surpass the supply of lithium from natural resources in the near future, posing a risk to the global lithium supply chain. Moreover, the continuous accumulation of end-of-life LIBs is expected to cause serious environmental problems. To solve these problems, recycling the spent LIBs must be viewed as a critical technological challenge that must be urgently addressed. In this study, recycling LIBs using pyrometallurgical processes and post-processes for efficient lithium recovery are briefly reviewed along with the major accomplishments in the field and current challenges.

변혁의 소용돌이 환경 속에서 국가의 잠재성장력을 가속화하고 지속적으로 유지하기 위해서는 국가차원에서 지식정보인프라와 지식정보시스템을 단계적으로 구축하는 것이 무엇보다도 시급한 과제이고, 구축된 시스템도 정부중심의 공급자위주 측면에서 벗어나 수요자 측면에서 지식정보를 생산.유통시키는 것이 바람직하다고 판단된다. 지식기반경제에서 과학기술정보의 역할은 대표적인 지식창출과 경쟁력 엔진으로 작용하게 될 것이고, 또한 엔진의 성능은 정보의 생산.유통.활용체제 시스템 수준에 의해서 좌우될 것이다.

Ppuri or Root technology primarily includes technologies such as casting, mold, plastic working, welding, heat treatment and surface treatment. It is regarded as an essential element for improving the competitiveness of the quality of final products. This study investigates the current status of smart factory implementation for Ppuri companies and analyzes the influencing relationships among various company factors. The factors affecting smart factory implementation for Ppuri companies are sales, exports, number of technical employees, and holding corporate research institutes. In addition, this research shows that even if smart factory implementation is pursued for data collection, data utilization is not implemented properly. Thus, it is suggested that the implementation of smart factories requires not only the availability of facilities and systems but also proper data utilization.
