In a wireless sensor network (WSN) setting, this paper presents a distributed decision-making framework and illustrates its application in an online structural health monitoring (SHM) system. The objective is to recover a damage severity vector, which identifies, localizes, and quantifies damages in a structure, via distributive and collaborative decision-making among wireless sensors. Observing the fact that damages are generally scarce in a structure, this paper develops a nonlinear 0-norm minimization formulation to recover the sparse damage severity vector, then relaxes it to a linear and distributively tractable one. An optimal algorithm based on the alternating direction method of multipliers (ADMM) and a heuristic distributed linear programming (DLP) algorithm are proposed to estimate the damage severity vector distributively. By limiting sensors to exchange information among neighboring sensors, the distributed decision-making algorithms reduce communication costs, thus alleviate the channel interference and prolong the network lifetime. Simulation results in monitoring a steel frame structure prove the effectiveness of the proposed algorithms.

본 연구에서는 과학의 윤리적 측면 중에서도 생물윤리와 관련하여 학생들의 의사결정력 함양에 적합한 주제를 선택하여 의사결정 단계를 세분화시켜 활동함으로써 학생들의 의사결정력 향상을 도모하고자 하였다. 생물 윤리 의사결정 활동지는 선행연구를 바탕으로 하여 재구성된 것으로서 문제인식, 정보 탐색, 대안 생성, 가치준거 설정, 대안 평가, 결과 검토의 단계로 구성되었다. 4차시에 걸쳐서 활동지를 투입한 결과 l차시에 비해 4차시의 학생들의 의사결정력은 향상된 것으로 나타났다. 의사결정의 활동 단계별로 살펴보면, 문제인식이나 대안 생성, 대안 평가하기는 4차시로 갈수록 향상되었으나, 정보탐색이나 가치 준거 결정하기, 결과 검토하기는 향상되지 않았다. 이는 단기간의 학습활동으로 의사결정의 세부 능력을 모두 향상시킬 수 없음을 알 수 있다. 또한 학생들의 의사결정 활동 단계에서 살펴보면, 정보탐색이나 대안 평가 기능의 수행이 낮은 것으로 나타났다. 이는 학생들이 생물 윤리적 쟁점에 직면하여 의사결정을 하는데 있어서 문제와 관련된 생물학적 지식을 제대로 적용하지 못하고 있는 것으로 볼 수 있다. 따라서 본 연구를 통해 현대의 과학 기술 사회에서 학생들에게 합리적인 의사결정력을 함양시키기 위해서는 교육과정에 생물학의 윤리적이고 도덕적인 요소를 고려한 구체척인 의사결정 활동이 포함되어야 하며 지속적인 학습이 이루어져야 함을 시사한다.

The purpose of this study is to find the factors that influence big data characteristics on decision satisfaction and utilization behavior, analyze the extent of their influence, and derive differences from existing studies. To summarize the results of this study, First, the study found that among the three categories that classify the characteristics of big data, qualitative attributes such as representation, purpose, interpretability, and innovation in the value innovation category greatly enhance decision confidence and decision effectiveness of decision makers who make decisions using big data. Second, the study found that, among the three categories that classify the characteristics of big data, the individuality properties belonging to the social impact category improve decision confidence and decision effectiveness of decision makers who use big data to make decisions. However, collectivity and bias characteristics have been shown to increase decision confidence, but not the effectiveness of decision making. Third, the study found that among the three categories that classify the characteristics of big data, the attributes of inclusiveness, realism, etc. in the integrity category greatly improve decision confidence and decision effectiveness of decision makers who make decisions using big data. Fourth, it was analyzed that using big data in organizational decision making has a positive impact on the behavior of big data users when the decision-making confidence and finally, decision-making effect of decision-makers increases.

The review of known decision-making support systems and technologies regarding the possibility of donation and transplantation showed that currently there are no systems and technologies of decision-making support regarding the possibility of donation and transplantation considering civil law. The paper models the decision-making support process regarding the possibility of donation and transplantation, which is a theoretical basis for the development of rules, methods and technology of decision-making support regarding the possibility of donation and transplantation considering civil law. The paper also developed the technology of decision-making support regarding the possibility of donation and transplantation considering civil law as a component of the Unified State Information System for Organ and Tissue Transplantation, which automatically and free of charge determines the possibility/impossibility of donation and transplantation. In the case of the possibility of donation, the admissible type of donation is also determined - over-life or after-life donation - and data about potential donor is entered in the relevant Donor Register. In the case of the possibility of transplantation, if the recipient needs a transplant of one of the paired organs or a part of the organ/tissue, then data about potential recipient are entered in the Transplantation List from both over-life and after-life donor, otherwise, if the recipient needs a transplant of a non-paired organ or both paired organs, then data about potential recipient are entered only in the Transplantation List from after-life donor.

Under limited resources such as budgets and experts, it is necessary to make decisions for promotion strategy of standardization work items in Information and Communication Technologies (ICTs). This paper focuses on a method of setting standardization promotion strategies for each item of personal information security standardization. As a decision making tool, the Importance Performance Anaysis (IPA) is applied and analyzed to the decision processes. The results are showed and illustrated for useful inputs to practical policy making in the field of standardization activities.

Covid-19 pandemic required all the world to use internet more actively. As a result, individuals and businesses are more open to digital threats. In order to provide security within the network, firewalls should be used. Firewalls act as a gateway between the corporate and the external networks. Therefore, it is more important than ever to choose the right firewall for each network. In this study, a new linear decision making model is proposed in order to find out the most suitable firewall and the estimates are completed according to this new model. Also, this model is compared with multi-objective optimization on the basis of ratio analysis (MOORA) method. This study distinguishes from other studies by proposing a new solution which ranks the firewall alternatives using linear and MOORA approaches. These approaches are used in many fields before but not in information technologies. Thus, this study can be considered quite innovative in terms of the problem it handles and the approaches used. It offers up-to-date and practical suggestions related to a decision making problem that has not been previously studied in the literature.

4차 산업혁명시대에 지능정보기술의 발전에 따라 인공지능의 다양한 역할이 주목을 받고 있다. 구글의 알파고를 계기로 인공지능은 더 이상 공상의 기술이 아닌 실존하는 기술이라는 점에서 사회전역에 파급효과를 가져올 것으로 예상되고 있다. 이에 따라 본 연구에서는 공공부문에서 인공지능을 활용한 정책결정의 가능성과 쟁점에 대한 탐색적 논의를 진행하였다. 이에 따른 연구목적은 세 가지 측면으로 구분되며, 첫째, 공공부문에서 인공지능이 정책결정까지 이어질 수 있는지에 대한 검토이다. 둘째, 인공지능의 정책결정과정이 기존 정책결정과의 어떠한 차이를 가지는가이다. 셋째, 인공지능이 정책결정에 도입될 경우에 나오게 될 쟁점을 다루었다. 이러한 인공지능에 의한 정책결정이 기존의 정채결정과 구별되는 점은 많은 정보와 대안에 기반한 합리적 의사결정, 투명성 및 신뢰성의 제고, 정책이슈에 대한 객관적인 시각, 신속한 의사결정 등이다. 하지만 인공지능의 정책의사결정시 야기되는 쟁점 역시 존재 한다. 첫째는 인공지능의 우월성, 둘째 윤리성 논란, 셋째 책임성, 넷째 기존 민주주의의 변화, 다섯째 공공부문 인력의 대체 논쟁, 여섯째 인공지능에 필요한 데이터 활용의 문제점 등이다. 공공부문 정책의사결정에서 인공지능의 도입은 향후 실현될 것이기 때문에, 사회적 충격을 최소화하기 위해 그에 따른 순기능과 역기능에 대한 융합적인 접근이 필요하다.

This paper examined whether strategic decision-making are related to its performance, using a empirical study. Variables of strategic decision-making process were procedural rationality, political behavior, and application of information technology, moderating variable was environmental unstability. The findings suggested that relations between strategic decision-making process and its performance was strongly correlated, but environmental unstability was not moderating for its performance.

The purpose of this study is to investigate the level of correctness accounting information with the two alternative forms of presenting information outputs. Specifically two different methods of presenting accounting information, the table form and the graphical form were employed to test the level of correctness of the accounting information user's decision making. Using college students as a surrogate decision maker, this research have found that there is no statistically significant difference in the correctness of decision making between the two groups, one group using the table form of accounting information and another group using the graphical form of accounting information.
