한국 보험업지수 구분에 관한 연구: 손해보험업지수와 생명보험업지수의 개발과 제안
이천영 ( Chun-young Lee ),백재승 ( Jae-seung Baek ),염명훈 ( Myeong-hoon Yeom ) 한국금융공학회 2020 금융공학연구 Vol.19 No.4
본 연구는 현재의 한국거래소(KRX) 보험업지수가 손해보험업과 생명보험업을 대표하는 지수로 적절한지 살펴보았다. 보험업은 손해보험업과 생명보험업으로 구분할 수 있으며 각각의 주가 변동에 미치는 요인이 다름에도 불구하고 현재 한국거래소에서는 손해보험업과 생명보험업을 구분하지 않고 KRX 보험업지수 하나로 통합하여 발표하고 있다. 미국의 경우 1987년 생명보험업지수를 발표하였고, 1992년에는 손해보험업지수, 생명보험업지수, 통합 보험업지수를 구분해서 발표하였다. 본 연구에서는 손해보험업지수와 생명보험업지수를 개발 및 제안하였고, 현재의 KRX 보험업지수가 한국의 손해보험업과 생명보험업을 대표하는지 그랜저 인과관계 검정과 VAR 모형을 활용하여 실증분석한 결과는 다음과 같다. 첫째, 그랜저 인과관계 검정 결과 손해보험업지수는 KRX 보험업지수를 통계적으로 인과하지 않았다. 이러한 결과를 바탕으로 KRX 보험업지수가 한국의 손해보험업지수를 대표하지 못한다고 해석하였다. 둘째, VAR 모형 추정 결과 역시 KRX 보험업지수가 손해보험업지수와 생명보험업지수를 대표하기에 적절하지 않다고 확인하였다. 결과적으로 현재 한국거래소에서 발표하는 KRX 보험업지수는 한국의 손해보험업과 생명보험업을 모두 대표하는 데에 한계가 있으며, 한국 주식시장에서 손해보험업지수와 생명보험업지수를 구분하여 개발 및 발표해야 할 필요성이 있음을 시사하고 있다. In this paper, we examine whether the current insurance industry index of Korea Exchange(KRX) is appropriate as an index representing the non-life and life insurance business. In the case of the U.S., the life insurance industry index was released in 1987, and the industry index for the life insurance, non-life insurance and the integrated insurance were released separately in 1992. The results of an analysis to verify whether the current KRX insurance industry index represent the Korea’s non-life and life insurance industry properly by using Granger causality test and VAR model are summarized as follows. First of all, this study developed and proposed the new index which subdivides into the non-life insurance industry index and the life insurance industry index. The result from the Granger causality test shows that there is no causal relationship between the non-life insurance industry index and KRX insurance industry index statistically. Based on the result, it is analyzed that the KRX insurance industry index does not represent the Korea’s non-life insurance industry index. Second, the results of VAR model estimation also confirm that the KRX insurance industry index is not suitable for representing both the non-life and life insurance industry index. As a result, the KRX insurance industry index currently announced by the Korea Exchange has limits in representing both the non-life and life insurance industry in Korea, and this study implies the necessity to develop and publish them separately in the Korean stock market.

鄭官愚,李千永 대구산업정보대학 1993 논문집 Vol.7 No.-
The Purpose of this study is to improve the basic skills of volleyball by finger elsticity necessary for exercise execution through the reinforcement exercise of finger elasticity and three stage direction course. We have studied on the improvement of the basic skills of volleyball by the extention of finger elasticity, making two classes(96 students) of J high school in Chinju the object of this study. As the result, we have reached the conclusion as follows : 1. This study resulted in being helpful in the skill improvement of over hand toss by the improvement of the sense of touch and balance for a ball. 2. In this study, the improved ginger elasticity resulted in being helpful in acquiring the basic skills of volleyball, such as serve, spike ect.. 3. The extended finger elasticity came to give confidence in acquiring the basic skills of volleyball.
