The purpose of this study was to investigate the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles. The subjects were 399 middle school students and 366 high school students in four middle schools and two high schools in metropolitan and small towns for one month from July 1, 2017. Data were analyzed through descriptive statistics, correlation analysis. Multiple regression was used to see how parent-adolescent communication styles, self esteem, and depression affect the career decision-making style. As a result, first, open communication with mothers has a statistically significant effect on the rational career decision-making style and open communication with fathers has a statistically significant effect on the intuitive career decision-making style of adolescents. Second, self-esteem of adolescents showed a positive correlation with rational career decision-making style and negative correlation with dependent career decision-making style, and depression showed a positive correlation with dependent career decision-making style. The results may help to understand the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles and be used for counseling intervention.

The research of the AI-based command decision support system was insufficient both quantitatively and qualitatively. In particular, in Korea, there was no research on concrete concept design at the current concept research level. This paper proposed the conceptual design of a tactical echelon command decision support system based on artificial intelligence(AI) according to the current army's doctrine of the operation process. The suggested conceptual design clarified the problem and proposed an appropriate process for design, and applied the function analysis method among rational techniques that enable conceptual design systematically.

학생은 미래뿐만 아니라 현재의 소비자로서 합리적인 의사결정을 통한 소비문화가 요구된다. 하지만 학생의 소비문화와 학교의 소비교육, 가정교육은 문제점을 안고 있다. 학생들은 물건의 필요성이나 용도, 금전상황, 가정상황 등을 전체적으로 고려하여 구매하기보다는 비계획적이고, 즉흥적이다. 학교에서는 교사들이 학생의 소비행위를 한 눈에 파악하여 교육적으로 피드백하기가 쉽지 않다. 가정에서는 학생들의 소비행위에 대한 의사소통의 길이 부족하다. 이에 본 연구는 소비의사결정 5단계와 Decision-Tree의 교육적인 면을 고려하여 합리적 소비 의사결정을 위한 6단계(문제정의, 정보탐색, 대안평가, 가치확립, 구매경험, 구매평가)를 새롭게 제안하고, 소비교실, 용돈 의사결정, 설문모듈을 통해 6단계를 체험하는 시스템을 설계하였다. 제안한 모델은 교사와 학생, 학부모 모두가 참여하여 학생의 계획적이고 합리적인 소비 의사결정 능력을 신장시키는데 도움을 줄 것이다.

Moral hazard and adverse selection often exist in asymmetric information environment. In this paper, quality investment decision problem is studied under moral hazard. A basic model for quality investment level decision is developed with the supplier as a principal and the buyer as an agent. And then we regard the supplier and the buyer's rational limitations to set up a model when the buyer's quality evaluation and processing activities are hidden. The model is optimized and the results under different backgrounds are discussed and compared. Results show that the buyer's quality evaluation level and processing level are mostly influenced by the supplier's quality assurance payment. Both the supplier and the buyer choose different quality investment levels under moral hazard because of the supplier's payment to the buyer in case of internal failure and external failure.

As the exiting school facilities become old and unfit for new curriculum, the systematical remodelling process based on its educational and physical functions is required. due to the inadequate maintenance and repairing practices, unnecessary costs are expended. Therefore, this study aims to establish a remodelling decision-making model for improving the educational environment of the existing school facilities. According to the budget system, it proposes the concept of remodelling that includes the activities of extension, reconstruction, repair and improvement. This study classifies the performance evaluation for school facilities as that of safety, durability and educational function, and articulates the assessment standards, methods and elements. In the end, it suggests a rational model for remodelling decision-making that can provide efficient and comprehensive remodelling process, economic and sustainable school development.

Autonomous agents need considerable computational resources to perform rational decision-making. The complexity of decision-making becomes prohibitive when large number of agents are present and when decisions have to be made under time pressure. One of approaches in time-critical domains is to respond to an observed condition with a predefined action. Although such a system may be able to react very quickly to environmental conditions, predefined plans are of less value if a situation changes and re-planning is needed. In this paper we investigate strategies intended to tame the computational burden by using off-line computation in conjunction with on-line reasoning. We use performance profiles computed off-line and the notion of urgency (i.e., the value of time) computed on-line to choose the amount of information to be included during on-line deliberation. This method can adjust to various levels of real-time demands, but incurs some overhead associated with iterative deepening. We test our framework with experiments in a simulated anti-air defense domain. The experiments show that the off-line performance profiles and the on-line computation of urgency are effective in time-critical situations.

This paper's aim is to suggest the Expert System for analyzing relative combat power in ground operations. Since relative combat power analysis in terms of comparing combat power of friendly forces with one of the enemy can determine how the commander and staffs operate their unit afterwards, it requires fast and rational decision-making process. However, it has relied on manual method so far though Tactical Information Communications Network(TICN) into which numbers of applications can be loaded has been developed over a decade. 3 methods for analyzing relative combat power were expressed as mathematic rules to be used knowledge in the expert system after reviewing previous studies, and it studied how intangible power as well as tangible were reflected on total combat power. The expert system that will be built using EXSYS Corvid tool is expected to lessen error rate, provide faster decision-making, and reflect both intangible combat power and tangible one by using an appropriate weights in analyzing relative combat power. Next research filed includes how to build expert systems related with military personnel and intelligence areas for fast and rational decision-making processes.

On this research, we classified Korean consumers into several comsumer groups based on the different decision-making process they endorse, and then investigated the difference among these consumer groups in frequency, expenditure, satisfaction in using different types of retail stores. For this research, we have surveyed consumers dwelling in Seoul and in near-Seoul areas in 2004. The following is the summary of the main results. First, 'enjoy shopping' group showed a high expenditure rate in department store shopping and internet shopping, whereas 'impulsive decision' group more frequently visited traditional market places, 'fashion pursuing' group and 'enjoy shopping' group visited department stores more frequently than traditional market places. Second, 'impulsive decision' group assessed that the traditional market place offers better price and quality. Also 'impulsive decision' group and 'enjoy shopping' group assessed positively on the AS provided by department stores, and assessed negatively on the AS provided by internet shopping malls. Finally, 'fashion pursuer' group preferred buying foods from traditional market places, while 'brand seeker' group and 'fashion pursuer' group preferred buying clothes from discount stores. While 'enjoy shopping' group showed a high preference in buying clothes in department stores, 'rational decision-making' group showed a low preference in buying clothes in department stores.

Cases and studies on the selection method of CTQ are relatively active, but there are few cases or studies on the selection method of CTP which is important in the device industry. In fact, many companies simply select and manage CTP from the point of contact based on their experience and intuition. The purpose of this study is to present an evaluation model and a mathematical decision model for rational and systematic CTP selection to improve the process quality of semiconductor equipment lines. In the evaluation model, AHP (Analytic Hierarchy Process) analysis technique was applied to show objective and quantitative figures, and Fuzzy decision-making model was used to solve the ambiguity and uncertainty in the decision-making process. Decision Value (DV) was presented. The subjects were 22 process factors managed in the Plating Process that the representative equipment line can do. As a result, the evaluation model proposed in this study can support more efficient and effective decision-making for process quality improvement by more objectively measuring the problem of subjective CTP selection in manufacturing sites.
