Although Android systems provide a permission-based access control mechanism and demand a user to decide whether to install an app based on its permission list, many users tend to ignore this phase. Thus, an improved method is necessary for users to intuitively make informed decisions when installing a new app. In this paper, with regard to the permission-based access control system, we present a novel approach based on a machine-learning technique in order to support a user decision-making on the fly. We apply the K-NN (K-Nearest Neighbors) classification algorithm with necessary weighted modifications for malicious app classification, and use 152 Android permissions as features. Our experiment shows a superior classification result (93.5% accuracy) compared to other previous work. We expect that our method can help users make informed decisions at the installation step.

급변하는 환경에 대응하기 위하여 최근 우리나라의 기업들은 책임경영제, 팀제, 수평 조직, 권한이양, Client/Server환경 등 다양한 기법들을 도입하고 있는데, 이들 기법들의 공통적인 특징을 한 마디로 표현하면 분권화라 할 수 있을 것이다. 따라서 분권화가 지닌 전체 최적인 아닌 부분 최적, 구성원간의 갈등, 조직 전체적 차원의 의사결정 및 실행의 어려움등과 같은 기본적인 문제들을 해결하기 위해서 이해관계자들간의 집단의사결정의 중요성은 분권화의 추세와 더불어 더욱 증대되고 있다. 본 연구는 S그룹의 산임과장 700여명을 6-7명을 한 조로 하여 총 110개 조를 편성한 후, 조별로 문제를 해결해 가는 과정을 직접 관찰하였다. 관찰결과 110조 중 100조 이상이 거의 동일한 의사결정 과정을 밟아갔으며 그들이 밟아 간 과정은 합리적 의사결정이론에서 제시하는 과정과는 거리가 멀었다.

IT 거버넌스(Governance)는 IT 관련 의사결정에 있어서 기업 내부 주체들의 권한과 책임, 의사결정 조직체계와 프로세스, 의사소통 방법, 의사결정 실현 체계, 조정과 통제, 그리고 의사결정에 대한 사후 평가 등을 통틀어 일컫는 말이다. IT가 기업 경영의 필수 인프라로 인식되고, 기업의 경쟁력 제고의 핵심 역량으로 자리잡으면서 IT 거버넌스의 중요성은 점차커지고 있다. 본 연구에서는 국내 주요 대기업들의 IT 거버넌스를 분석하였다. 4개의 국내 대기업들에 대한 심층 인터뷰를 바탕으로, 이들 기업들이 어떤 조직 체계와 과정, 의사소통 체계, 그리고 성과 측정 방법 등을 가지고 IT 관련 의사결정을 하는지를 살펴보았다. 국내 대기업들은 IT 서비스를 전문적으로 제공하는 IT 서비스 계열사를 이용하여 IT 기능을 아웃소싱하고 있었으며, IT 관련 최종 의사결정은 IT 전문 조직이 아닌 비즈니스를 담당하고 있는 경영자들이 하는 것으로 나타났다. 국내 대기업들의 IT 서비스에 대한 계약과 성과 측정은 서비스 수준 협약을 통해 이루어지고 있었으며, 국제적으로 인정되고 있는 프로젝트 관리 방법론과 균형성과 기록표 등도 널리 사용하고 있었다. 이러한 연구는 국내 대기업 내의 IT 서비스 전문 기업들의 미래 역할 정립과 정부 기관이나 공기업들의 IT 거버넌스 체계 확립에 있어서 벤치마킹 근거로 활용될 수 있다. 또한 국내 대기업들의 IT 거버넌스 체계의 효율성 등을 측정하기 위한 기초 자료로 이용될 수 있다.

In the process of managing organization, the strategic decision-making and corporate performance are not independent, but they are interdependent each other. In most Korean firms, decision-making power and authority are concentrated on the higher echelons of managerial hierarchies. Examining big five trading conglomerates in Korea, this present paper investigates the relationship between strategic decision-making and a corporate performance. Although a number of review studies on Korean management have been developed over the years, there have been less works designed with decision making in mind. In order to achieve research objectives, this paper predicted some hypotheses, and the major findings include: 1) the influence of Korea's long-standing Confucian tradition and culture dominated across organizations, there have not been significant changes in decision-making process within big five trading firms; 2) top executives' excessive involvement in decision-making process does not hinder corporate performance. This result implies that the decision power is still tended to be centralized in the hands of the top management. 3) However, the power of Board of Directors in decision-making has become increasingly important; and 4) decision makers do not tend to misuse or abuse their political position and power for their own interests.

The purpose of this research is to derive and evaluate priorities for critical factors that must be determined before an enterprise adopts a cloud computing service. AHP analysis techniques were used to reflect decisions made by experts as research methods. AHP is a decision-making technique that expresses complex decision-making problems hierarchically and derives the best alternatives through pairwise comparison between the items of the hierarchy. Compared to the existing statistical decision making techniques, the decision making process is systematic and simple, making it easy to understand. In addition, the procedure is also reasonable by providing an indicator to determine the consistency of the decision maker in the analysis process. The analysis results of this research showed that security was the first priority, reliability was the second priority, and economic efficiency was the third priority. Among the factors in the first-priority security items, the access control rights and the safety factors of external threats are the most important factors. Research results can be used as a guideline in future practice, and it is necessary to evaluate, compare and analyze the satisfaction of companies that have adopted cloud computing services in the future.

The recent keen global competition makes cooperative Labor-Management relations as one of the minimum requirements for the business firms in order to survive. Accordingly, this study focused upon the comparative analysis of the traits of some major countries' Labor-Management Joint Consultations for the purpose of explaining the core characteristics of them. The way how to develop and enhance the Labor-Management Joint Consultation in Korea was also suggested. As a result, this study shows that the social background of, the authority of, and the relationship with collective bargaining of the the Labor-Management Joint Consultation differed in great extent among the countries, and that these differences caused the various consultation patterns in each country. For example, the Labor-Management Joint Consultation was introduced and used voluntarily in the U.S.A. and Japan, while it was enforced by law in Korea, Germany, and France. Also, co-determination has been popular in Germany, France, and The U.S.A., but only the advising and consulting have been dominant in Korea and Japan. However, the rapid change of business environment and the increase in employees' need will make the co-determination as a desirable pattern even in Korea.

Patients' right to self-determination and consent in these laws are related to civil law. even though they are closely related to the civil law in relation to patients' right to self-determination and consent. In order to consistently operate medical administration, it is necessary to understand the principles of civil law decision-making.

Computing loud arrival times were, important data Clouding and, without being limited to the device, may process the information. Recently, work environment and improved access to Cloud and Mobile, this decision has been made to take effect immediately. However, when such important decisions of the government, the security is required. In this paper, we study the network access and control in IoT, Cloud, Bigdata, Smartwork System applied to Mobile. Study the authentication, authorization, and security for each security level Level of Service to connect to the DB information. Research of this paper will be used as the basis for the information processing and decision-making system design and construction of public institutions and agencies as important information for the protection Smartwork System.

This study explores the IT governance structures of the Korean conglomerates. It investigates IT organization structures, decision making frameworks and processes, communication channels, implementation mechanisms, and performance evaluation methods around IT activities of the Korean conglomerates by analyzing four different cases. The results show that all of the conglomerates have an IT service firms as one of their subsidiaries, and all the subsidiaries in the conglomerates outsource their IT divisions to the IT service firms, The client firms in the conglomerates operate IT strategy and planning teams to coordinate their IT activities with their outsourcing partners. The IT governance archetype of the Korean conglomerates is found to be "business monarchy" because the client firms mostly make IT decisions. However, the IT service firms provide the information of IT trends and solutions to their clients, so the IT governance archetype of input framework for IT decisions can be "IT monarchy". In addition, the conglomerate which has the more centralized IT governance architecture appears to prefer the more integrated implementation mechanisms for IT decisions. The results of this study are expected to be used as a benchmarking model for the organizations which try to develop an effective IT governance structure.
