  • 지연 차등화 모델은 각 클래스의 지연 차별 변수에 따라 차등화된 서비스를 제공한다. 따라서 각 클래스의 패킷별 평균 대기시간이 지연 차별 변수에 비례한다. 유선 환경의 지연 차등화 모델인 WTP를 무선 환경에 적용시킨 WWTP는 큐의 처음 패킷의 블록으로 인한 큐의 전송 중단 현상을 개선하였다. 이로 인해 클래스별 서비스 불공평성이 줄어든다. 그러나 여전히 채널 오류기간에 비례하여 전송의 편중과 중단현상이 발생하는 단점이 있다.본 논문은 WWTP에서 발생하는 서비스 편중과 중단 현상을 개선하기 위한 보상 정책을 제안하는 스케쥴러를 제안한다. 제안된 모델은 에러 기간동안 에러 프리 서비스를 가상적으로시뮬레이션하여 정상 서비스와의 차이를 알아내고 이를 바탕으로 보상 정책을 수행한다. 결과적으로 지연 차등화 모델인 WWTP에서 발생하는 서비스 중단을 개선하면서 정상적인 채널상태와 유사한 서비스를 제공한다.

  • The compensation system in industrial accident insurance is systemized with "either receiving all or no benefits at all" according to "admited or denied as an industrial accident". Therefore, they are centered on the decision as "industrial accident" or "non-industrial accident", but judging between the two is very complicated, and has inherent conflicting factors. In the early stage of industrialization, industrial accident compensation was based on the indemnity liability for employer's faults. In order to be compensated any damage, the injured worker should prove that the accident was not due to his or her faults. However it was very difficult for injured worker or his or her family to prove the employer's faults, so it was almost impossible to get compensation. Thereafter industrialization progress and improvement of workers' political status lead to conversion from principle of liability with employer's faults to principle of liability without employer's faults. In addition to that, coverage of industrial accident compensation was also expanded. This improvement strengthened the benefit payment principle of "All or Nothing". Even though the "All or Nothing" principle provokes tremendous criticism, the reason why it's difficult for industrialized countries to adopt partial compensation system, is that partial compensation system worsens the administrative hardship, therefore industrialized countries overcome the restrictions of the "All or Nothing" principle with making balance in provisions for any risk to some extent. However, in Korea because the general compensation system for covering medical cost and income loss from accidents, is not equipped, it could be possible to cause acute conflicts with regard to coverage of industrial accidents. Therefore it is required to improve the industrial accident insurance with the acceptance of the significance and logic of discriminated compensation, and create the integrated compensation system in the long run.

  • Korea has entered into an aging society at an exceptionally high speed. Increasing aged workers give pressure on Korean companies with seniority based pay system with labor costs. The wage peak system has been introduced to Korean companies as an alternative to early retirements. The wage peak system currently adopted in Korea is mainly the aging-limit-security model. But in the future we should actively adopt the employment-extension model. To operate wage peak system successfully, I suggest introduction of the individual wage peak system, development of suitable jobs for the aged, selective application by job classification, incentive graded by performance evaluation, and working hour reduction with the decreased rate of wage.
