In this study, we propose an efficient two-phase heuristic policy, called an acceptance tolerance control policy, for Infrastructure as a Service (IaaS) cloud services that considers both the service provider and customer in terms of profit and satisfaction, respectively. Each time an IaaS cloud service is requested, this policy determines whether the service is accepted or rejected by calculating the potential for realizing the two performance objectives. Moreover, it uses acceptance tolerance to identify the possibility for error with the chosen decision while compensating for both future fluctuations in customer demand and error possibilities based on past decisions. We conducted a numerical experiment to verify the performance of the proposed policy using several actual IaaS cloud service specifications and comparing it with other heuristics.

The Jeju April Third Tragedy saw an estimated 14,000 and possibly many thousands more Jeju Islanders killed amid the political turmoil of a re-merging Korean stated after the Japanese occupation. US troops were stationed on the island province before and during the Tragedy which lasted from 1947 to 1954. The aim of this article is to present theoretical and practical issues of the unfnished business of reconciliation and social healing for the victims of the April Third Tragedy; for survivors, for family members, and for the memories of the decreased. This process requires the engagement of as many of the actors at that time, in order to conclude the story of April 3rd Tragedy. Based on 13 years of’ collaborative efforts setting up a vision of Jeju as World Peace Island, there is now formal recognition of the April 3rd Tragedy event. We have hoped for a future beyond the trauma and tragedy of the Mass-killing of Korea Jeju Islanders during and after the US Peacetime Occupation ( 1947-1954). Even though it has taken 10 years to translate the Jeju April 3 Incident Investigation Report of 2003 into an English edition in 2013, I believe, it provides a cornerstone for Jeju islanders to open a new Age of Social Healing for the Mass Killing of Korea Jeju Islanders ( the Tragedy) while under and then after US Military Peacetime Occupation (1947- 1954).
