Recent advancements in cloud computing have significantly increased its importance across various sectors. As sensors, devices, and customer demands have become more diverse, workloads have become increasingly variable and difficult to predict. Cloud providers, connected to multiple physical servers to support a range of applications, often over-provision resources to handle peak workloads. This approach results in inconsistent services, imbalanced energy usage, waste, and potential violations of service level agreements. In this paper, we propose a novel engine equipped with a scheduler based on the Hot-Threshold concept, aimed at optimizing resource usage and improving energy efficiency in cloud environments. We developed this engine to employ both proactive and reactive methods. The proactive method leverages workload estimate-based provisioning, while the reactive Hot-Cold Scheduler consists of a Predictor, Solver, and Processor, which together suggest an intelligent migration flow. We demonstrate that our approach effectively addresses existing challenges in terms of cost and energy consumption. By intelligently managing resources based on past user statistics, we provide significant improvements in both energy efficiency and service consistency.

Forming a network, through Social Network Services (SNS), among a group of people who share the same hobby or interests could increase the information sharing among the members at an exponential rate. Moreover, SNS users' behavior extends beyond the traditional introverted consumption behavior to a proactive behavior by owning or actively sharing product information. For firms, such proactive consumer behavior translates into marketing effects such as the word of mouth (WOM) effect. Therefore, SNSs are accepted not only as a communications channel between firms and consumers but also as marketing channel, suggesting the possibility of a new revenue source. In this context, we will explore into the factors of SNS contents which conserve firms' image and product information, and effects of the factors on consumer attitude and WOM.

The emergence of ubiquitous autonomic computing and network environment will change the service architecture information system which will be a new application area in SCM/logistics systems. In this study we surveyed the technical trend map of ubiquitous and its application in SCM/logistics support system design. We described the evolutional model of ubiquitous computing community for SCM/logistics system. It is consisted of three view points; self-growing, autonomic, and context-aware, which will allow the decision makers to be benefited from web and mobile technology and are useful for proactive SCM/logistics support system. Finally, we suggested a cooperative research planning for the development ubiquitous system between the government research center, university, and industry research activities.

본 논문에서는 Ad Hoc Network에서 사용되는 proactive 라우팅 프로토콜과 reactive 라우팅 프로토콜의 혼합인 hybrid 라우팅 프로토콜에 대해 제안하였다. 본 논문에서는 기존의 hybrid라우팅 프로토콜이 ZRP와는 달리 Ad hoc 네트워크를 구성하는 노드들 중에 네트워크 서비스를 제공해주는 특별한 노드를 설정하여 라우팅 하는 방법을 제안한다. 이러한 역할을 해주는 특별한 노드를 본 논문에서는 C-Node라 부른다. C-Node를 이용한 라우팅으로 기존의 라우팅 프로토콜보다 경로 설정 시간과 flooding시간을 줄임으로서 효율적인 라우팅을 수행할 수 있게 된다.

In operating distributed systems, proactive management is one of the major concerns for better quality of service and future capacity planning. In order to handle this management problem effectively, it is necessary to analyze performances of the distributed system and events generated by components in the system. This paper provides a rule-based event parsing engine for proactive management. Our event parsing engine uses object hooking-based and event-token approaches. The object hooking-based approach prepares new conditions and actions in Java classes and allows dynamically exchange them as hook objects in run time. The event-token approach allows the event parsing engine consider a proper sequence and relationship among events as an event token to trigger an action. We analyze the performance of our event parsing engine with two different implementations of rule structure; one is table-based and the other is tree-based.

본 논문에서는 van Hiele의 단계적 교수법에 근거한 예비교사들의 수학 수업에서 학생들을 지식 구성의 주체로 만드는 탐구 활동의 활성화 방안을 탐색하고자 한다. 이를 위하여 예비교사들의 수업 지도안과 수업 시연에서 van Hiele의 단계적 교수법의 정보 단계와 안내된 탐구단계에서의 교수 학습 상황을 분석한다. 이와 같은 교수 학습 상황에서 탐구학습 또는 발견학습의 활성화 가능성을 탐색한다. 특히, 본 연구에서 삼각형의 외심과 내심을 두 도형의 위치관계라는 개념구조 안에서 삼각형과 원의 위치관계를 출발점으로 설정하는 방안을 제안하고 이 제안에 대한 구체적인 실행 방법으로서 "사실1: 삼각형의 외접원은 유일하게 존재한다."와 "사실2: 삼각형의 내접원은 유일하게 존재한다."는 두 가지 사실의 도입과 증명을 van Hiele의 단계적 교수법에 근거한 새로운 지도방법으로 제시하고자 한다.

최근 이슈가 되고 있는 '빅 데이터'의 사회적 잠재성을 정부의 대국민 서비스와 연계지어, 정부의 행정서비스 혁신에 빅데이터의 사상이 기여할 수 있는 구체적 방안을 모색하였다. 특히 주민 생활공간과 정부 업무공간의 이원화가 초래한 정부 행정서비스의 본원적 한계를 행정 프로세스의 외부 확장을 통해 극복할 수 있는 방안을 제시하였다. 또한 이로부터 제기될 수밖에 없는 선결과제, 즉 주민 공간의 각종 사물데이터를 어떻게 행정 데이터 영역에 편입할 것인가에 대한 논의를 포함하였다. 이로써 행정서비스 영역에 대한 빅데이터 기반 조성이 신고와 신청에 의존하던 수동적 행정서비스를 선제적으로 바꿔내는데 어떤 역할을 할 수 있는지에 대한 시사점을 제시하였다.

Big data technology is being used in various fields followed by the development of information and communication technology. In the corporate and public sectors, diverse system platforms are built and operated due to the needs of users, but efficiency is low because they are built from an individual service perspective rather than an integrated service perspective. In this study, the relationship between presenting the characteristics of the type of shared information platform, the integration plan, and integration performance of the shared information system platform was analyzed. The results of the study will provide guidelines for the integration of shared information system platforms by the government and private companies in the future.

In-flight service, depending on the perceptions of service satisfaction because ever turns into a variable, which enables service providers the flexibility of a variable in the end flight service to suit your needs to providing comprehensive and proactive services of the crew will be motivated. In addition, the service provider's motivation to work in a confined space on board the flight service characteristics in-flight service will be a major impact on the environment. This service-oriented environment, in-flight service and motivation in order to verify the impact on services in Cape factors as independent variables and the dependent variable service-oriented multi-regression analysis was performed. As a result, the motivation of the crew and the crew of the service-oriented, with a voluntary service crew services dependent variable parameters that affect the behavior of the acts. Services and service-oriented motivation Cape factors significantly influence both the irradiated while the impact on voluntary service and results verification service aesthetics, cleanliness, and physical service environment, only the voluntary services of the crew a positive effect on that the effects were investigated.
