Purpose: The purpose of this study was to examine nurses' critical thinking disposition and knowledge sharing activity and professional work environment on clinical decision-making ability. Methods: The data collection period for this study was from May 24 to May 31, 2021. The data were collected from 167 nurses who consented to participate in this study and have worked for more than one year at general hospital in Seoul. The data were analyzed using the SPSS/WIN 25.0 program. Results: A significant positive correlation was found between clinical decision-making ability and critical thinking disposition, knowledge sharing activity, and a professional work environment. Critical thinking disposition (β=.32, p<.001), knowledge sharing activitiy (β=.24, p=.002) and professional work environment (β=.20, p=.006) had a significant effect on clinical decision-making ability. These factors explained 35.5% of clinical decision-making ability (F=24.22, p<.001). Conclusion: Therefore, in order to develop the critical thinking disposition of nurses, development of systematic educational programs and strategies for practical application are needed. Through this, nurses can improve the professional decision-making ability and clinical performance ability.

The purposes of this study were to examine if a decision making by a tourist sequentially or hierarchically occurs in a tourism destination and to test determinants that have an effect on both a sequential and non-sequential decision making. An instrument for the study was developed with three steps. A total of 420 and 380 questionnaire were collected respectively for the first two round surveys. For the third step, a pilot test was conducted with 30 respondents. And the data analysis utilized SPSS 18.0. A logistic regression analysis with variables of tourism activity and demography was employed to investigate the factors that affect a sequence of decision-making process. As an important result, the higher the age of the tourist in a tourism destination, the more conspicuous the consumption expenditure is made through the sequential decision-making process. Additionally, it is unreasonable to apply the premises and assumptions in extant consumer behavior to tourist behavior. The process of decision making by tourists in tourism areas is driven by either non-sequential or non-hierarchical decision-making process. More discussion and implications were provided.

Performing 'Mega Project' in which various stakeholders are involved is difficult to control due to the respective conflicting objectives. Urban regeneration which is being challenged issue in various ways can be defined as the mega project. Since the mega project like urban regeneration a long-continued project and includes a lot of participants whose benefits conflict, cooperation among stakeholders is essential. Moreover, as the project goes, diverse decision making situations which require collaboration happen, and if proper decision making cannot be given at that time, the whole project would have critical effects. Also, since each activity concerns numerous stakeholders, prompt decision making is difficult in the mega project. Therefore, the objective of this study is to support stakeholder's cooperative decision making in order for conducting successful project. For the purpose of the paper, the concept of cooperation in mega project is redefined and a cooperative decision making framework is suggested. Also, the term of governance, which means cooperative mechanism based on the mutual trust, information sharing and partnership, is applied to the newly defined cooperation. The suggested cooperative decision making framework contains the structure of stakeholders in urban regeneration project which enables participants to understand the relationship among bodies and checklists for supporting decision making appropriately. The application of the framework proposed in this research is expected to contribute subjects' suitable decision making by providing proper information in a timely manner.

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.

Stochastic resource-constrained project scheduling problem is an extension of resource-constrained project scheduling problem such that activity duration has stochastic nature. In real situation where activity duration is not known until the activity is finished, open-loop based static policies such as activity-based policy and priority-based policy will not well cope with duration variability. Then, a dynamic policy based on closed-loop decision making will be regarded as an alternative toward achievement of minimal makespan. In this study, a dynamic policy designed to select activities to start at each decision time point is illustrated. The performance of static and dynamic policies based on variable neighborhood search is evaluated under the discrete-event simulation environment. Experiments with J120 sets in PSPLIB and several probability distributions of activity duration show that the dynamic policy is superior to static policies. Even when the variability is high, the dynamic policy provides stable and good solutions.

Human decision-making is a complex behavior. A replication of human decision making offers a potential to enhance the capacity of intelligent systems by providing additional user assistance in decision making. By reducing the effort and task complexity on behalf of the user, such replication would improve the overall user experience, and affect the degree of intelligence exhibited by the system. This paper explores individuals' decision-making processes when using recommender systems, and its related outcomes. In this study, human decision-making (HDM) refers to the selection of an item from a given set of options that are shown as recommendations to a user. The goal of our study was to identify IS constructs that contribute towards such decision-making, thereby contributing towards creating a mental model of HDM. This was achieved through recording Electroencephalographic (EEG) readings of subjects while they performed a decision-making activity. Readings from 16 righthanded healthy avid readers reflect that reward, theory of mind, risk, calculation, task intention, emotion, sense of touch, ambiguity and decision making are the primary constructs that users employ while deciding from a given set of recommendations in an online bookstore. In all 10 distinct brain areas were identified. These brain areas that lead to their respective constructs were found to be cingulate gyrus, precentral gyrus, inferior parietal lobule, posterior cingulate, medial frontal gyrus, anterior cingulate, postcentral gyrus, superior frontal gyrus, inferior frontal gyrus, and middle frontal gyrus (also referred to as dorsolateral prefrontal gyrus (DLPFC)). The identified constructs would help in developing a design theory for enhancing user assistance, especially in the context of recommender systems.
