  • This study used the hypothetical path model to investigate individual traits(attachment, reciprocal relationship, and self-esteem), situational evaluation(justification, and intention) and jealousy level in adolescents. Subjects were 853 7th, 9th, 11th grade students in the city of Daegu. Results showed that scores of girls were higher than boys on self-reported and peer-reported jealousy level, attachment, reciprocal relationship, adaptive expression and non-adaptive expression. Scores of boys were higher than girls for self-esteem, justification. Self-reported jealousy level was affected by situation evaluation(justification and intention) and attachment. Peer-reported jealousy level was affected by reciprocal relationship. Jealousy expression modes were affected by self-reported jealousy level and attachment.

  • This paper is concerned with the critical issue of allocating limited corporate resources among multiple products and between production and marketing functions of a functionally decentralized firm where the two geographically remote functions independently make decisions pertaining to their own decision-making domain. We attempt to demonstrate how IT can contribute to enhancing the quality of coordinating production and marketing functions from the perspective of resource allocation. To this end, we propose a prototype named ITBCS (IT-Based Coordination System) that works under LAN supported computing environments. We develop a comprehensive coordination scheme that can handle various cost functions for the resource constrained, multiple product case that huts been tittle discussed in literature. A preliminary version of ITBCS has been implemented for a hypothetical situation where LAN electronically wires distributed marketing and production computing nodes. Managerial implications are also discussed.

  • Numerical and experimental works have been made in order to figure out the physical mechanism of thermal storage system for the determination of optimal design and to enhance the thermal efficiency of the system. To this end a computer program is developed and evaluated successfully against experimental data measured with a bench scale facility. Considering the thermal efficiency of storage is critically impaired by the mixing effect, the minimum flow mixing situation is calculated by the assumption of uniform plug-type flow as a reference condition. Further a parametric systematic calculations have been made for a hypothetical full-scale storage system with Fr, storage dimension, diffuser type and loading hour, etc.

  • This Paper aims to develop container terminal simulation models for medium and long term decision makings. It first undertakes in-depth survey of literature. finds its shortcomings and suggests some directions for improvement. It then proposes detailed design for the simulation models. Based on this it finally developes several simulation models and applies them to a hypothetical situation of a container terminal development. The results reveal that basic design questions such as length of quay, number of quay crane, size of storage area are well produced through the models.

  • The design and philosophy are presented for an intelligent aid for a hyman operator who must diagnose a novel fault in a physical system. A novel fault is defined as one that the operator has not experienced in either real system operation or training. When the operator must diagnose a novel fault, deep reasoning about the behavior of the system components is required. To aid the human operator in this situation, four aiding approaches which provide useful information are proposed. The aiding information is generated by a qualitative, component-level model of the physical system. Both the aid and the human are able to reason causally about the system in a cooperative search for a diagnosis. The aiding features were designed to help the hyman's use of his/her mental model in predicting the normal system behavior, integrating the observations into the actual system behavior, or finding discrepancies between the two. The aid can also have direct access to the operator's hypotheses and run a hypothetical system model. The different aiding approaches will be evaluated by a series of experiments.

  • This paper estimates the relative risk aversion coefficients of apple farmers. Two hypothetical situations are designed and two-stage questionnaires are conducted for each situation. A utility function that has constant relative risk aversion was used, and it was assumed that the relative risk aversion coefficients follow a log-normal distribution. To reduce the hypothetical bias, the data was collected from repetitive questions. As a result, the mean and standard deviation of the relative risk aversion coefficients of apple farmers was 10.915 and 7.516, respectively. The relative risk aversion coefficients conditional on a survey response in each category were also measured. These findings can be used as parameters to analyze the effects of risk management tools.

Estimating Willingness to Pay for Local Festival and Place Attachment in the COVID-19 era: A Case Study of Daegu Chimac Festival (코로나 시대의 장소 애착에 따른 지역 축제 입장료 지불 의사 평가 - 대구 치맥페스티벌을 중심으로 -)

  • Due to the spread of COVID-19, the domestic market was inevitable to face the crisis of tourism industry. Accordingly, most of local festivals decided to cancel or postpone, and have been in difficult situation. In addition, people also have experienced the thrist of cultural activities and tours. However, this situation can also be opportunity to find the clues for activating local festivals in the post-COVID-19 era with estimating the preservation value and deriving the determinants for it. Therefore, this study economically assessed the value of the local festival, Chimac Festival in Daegu, under the hypothetical financial crisis situation for COVID-19. Consequently, monthly income, age and place dependence was found to be influential for Daegu and nearby area citizens to have willingness to pay for the Chimac Festival in Daegu. The result shows that respondents are willing to pay 16,909 on truncated average. Thus, total value of Chimac Festival was estimated as 9.376 billion won.

  • The destructive power of cyber threat arrived to until the phase which it threatens to direct and seriously in national security undergoes an important national institutuin hacking event of 2004 and Internet paralysis accidents of 2003. 1. 25. So Cyber terror and Cyber warfare is not the hypothetical enemy situation. It is more actual security situation and identify as magnification of warfare concept of incapacitation national important ability include military command system of the adversary, communication, energy, finance and transportation system. consequently, with the progress of cyber threat, it is necessary that looking at a number of general plan to make up for the weak points in cyber warfare operation system. Thus, the focus of this study is to examine new ways of developing a comprehensive cyber security management system.
