선행 연구에서는 한국 KOSPI 상장 기업을 대상으로 한 실증 분석을 통해 균형적 ESG 전략이 기업 성과에 양 의 영향을 미칠 수 있음을 확인하였다. 그러나 KOSPI 기업을 대상으로 한 실증 분석에서는 재무적 인과 관계에서 만 유의성이 확인되었으며, ESG 균형 전략이 부분적으로만 작용한다는 한계를 보였다. 이에 본 연구는 글로벌 500 대 기업을 대상으로 연구 범위를 확장하여 균형적 ESG 전략을 재분석하였다. 분석 결과, 재무 성과와 기업 가치 측면에서 균형적 ESG 전략이 상호작용 항으로서 모두 긍정적인 영향을 미치는 것으로 나타났다. 따라서 본 연구는 기업이 ESG 경영을 추진할 때 균형적 전략의 중요성을 다시 강조하며, ESG와 기업 성과를 증진하기 위한 방안 으로 균형적 ESG의 필요성을 실증적으로 확인하였다.

Crimes with explosives is one of the mass-destructive crimes that involves the most victims. It is heavily punished under the Korean laws. Mid-eastern area is one of the leading places that are home to improvised explosive device attacks, in the form of religious or political terrorism because of its convenience of use, production and disguise. Improvised bombs are permeating into domestic crimes in Korea as their tools. Use of explosive substances are strictly restricted in this country, but it is not impossible to find its information online and to create private explosives with a bit of interest. And they are being traded in the grey market. For this reason, this thesis offers the method of an efficient safety control of explosive substances, which can be used as raw materials for improvised explosive devices, in order to protect citizens’lives and properties and to promote national security down the road.

As Crosby notes, the most companies spend 15 to 20% of their sales dollars on quality costs. Generally the most effective way to manage quality costs is to avoid having defects in the first place. In this paper we have studied about the repair(service) problem of domestic gas boiler within warranty period. We develop a system, which man could find the cause of the problem at an early stage and could devise a countermove to the problem under supposing that the service(repair) rate follows exponential distribution and the product is manufactured lot-for-lot continually. Using the developed early sensing system. it is expected to improve the reliability of the product, to save expenses of company and to improve customer’s satisfaction. And the system will be expended to incorporate information technology, which can detect the repair rate automatically.
