  • Generally, Hwabyung is more commen in older women, in low educational group. Many psychiatrists explain it as the illness originated from a series of psychological stresses. And they think that Hwabyung patients have somatization disorder, anxiety disorder, and, major depression. But, many of oriental medical doctors explain it as symptoms having the character of fire. In order to investigate the clinical aspects of Hwabyung, this study was carried out in department of oriental neuropsychiatry at Kyung Hee Medical Center. The subject was 34 year old female who was an inpatient in K.M.C from Aug. 14 Aug 26, 1996.The results of the study showed that familial problem and long-termed(about 10 years) stressed situation drove her to Hwabyung. This seems to be related to Korean traditional culture. That is, Korean women were exposured to familial problem(related to mother-in-law, and, her husband), and, poverty, etc. But they had to be patient of this situation. Nowadays, though this situation is rather improved, Hwabyung remains a problem with us, because many people still suffer from Hwabyung.

  • In order to solve the problem that the current network security situation assessment methods just focus on the attack behaviors, this paper proposes a kind of network security situation assessment method based on Markov Decision Process and Game theory. The method takes the Markov Game model as the core, and uses the 4 levels data fusion to realize the evaluation of the network security situation. In this process, the Nash equilibrium point of the game is used to determine the impact on the network security. Experiments show that the results of this method are basically consistent with the expert evaluation data. As the method takes full account of the interaction between the attackers and defenders, it is closer to reality, and can accurately assess network security situation.

  • We attempted to develop a problem-based learning (PBL) module for integrated education in dental hygiene with the aim of helping students gain clinical competencies necessary for dental hygienist work. To develop the PBL Module for Clinical Dentistry in Dental Hygiene course, the researchers identified literature related to not only educational technology, but also medical science, nursing, dentistry, and dental hygiene. During the design phase of the PBL module, problem scenarios and a plan for the teaching and learning process were developed. Developing problem scenarios involved describing a problematic situation and three questions related with that situation. To cultivate competencies required in dental clinics, each question was related to the diagnosis of a dental disease, dental treatment, and dental hygiene procedures for care. Teaching-learning process plan included the designs of operating environment, operational strategies, learning resources, facilitation of problem-solving process, and evaluation. It is necessary to evaluate the PBL module for integrated education in dental hygiene to confirm its effectiveness.

  • This study was based on resilience approach to find out elementary first, second, and third year students' differences of social support and problem solving ability defending on their family situation (low-income divorced family or normal family) by comparing their sex and age. In addition, the purpose of this study was to find out the effect of factors (social support, problem behavior, and problem solving ability) of children defending on their family situation and age. Moreover, it was aimed to find out the effect of social support and problem solving ability of low-income divorced family's children on their problem behavior. Subjects were 165 children in elementary school (grade 1, 2, and 3). For this study two groups were used for comparison. First, low-grade elementary school children with low-income divorced parents (N=87), "group D" and second, with low-income non-divorced parents (N=78) "group N". The questionnaire, picture cards, and teacher's report was used to determine social support perception, problem-solving ability, and problem behavior, respectively. Results showed that "Group D" was determined to show regarding social support, problem-solving ability, and problem behaviors worse than "group N". In conclusion, problem behaviors of "group D" were affected by social support and their problem-solving ability.

  • In order to minimize casualties from marine vessel accidents that occur frequently at home and abroad, it is important to ensure the safety of the passengers aboard the vessel in the event of an accident. There is an EPIRB system as a system for disaster preparedness in the marine situation currently on the market, but there is a problem that the price is very expensive. In order to overcome the cost problem, which is a disadvantage of previous system, LoRaWAN-based communication is used. LoRaWAN communication-based vessel positioning and risk detection system based on LoRaWAN communication transmits measurement data of each module using two Beacon and GPS modules to stably perform position measurement for both indoor and outdoor situations. The rider danger situation detection system can detect the safety status of the rider using the 3-axis acceleration sensor, collect data from the rider positioning system and the rider safety status detection system, and send to server using LoRa communication. When conducting communication experiments in the long-distance maritime situation and actual communication experiments using the implemented system, it was found that the two experiments showed over 90% communication success rate on average.

  • Caring is an essential element of nursing. In a family with a patient. a critical situation may happen not only for the patient but also for the members of the family. Therefore, a caring service from the healthcare providers can also be requested for the family members. The movie 'Mabin's Room' deals with family problems. In this study, the assessment, problem, diagnosis and planning for the family nursing situation for family problems were made focusing on the role of characters in the movie 'Mabin's Room'. Regarding family nursing intervention, the framework of the story 'Mabin's Room' was reorganized to solve the problems based on the role of community health nurse. In this scenario approach method, the situation in the movie is used without change but the scenario related to the roles (or communication) of community health nurse for solving the family problems is added. It is a problem solving oriented method by reorganizing the scenario in a movie story situation. The reorganized scenario in this study is just an example of scenario approach method. Community Health Nurses can cultivate their creativity by solving various problems in the community by adopting or modifying this simple scenario in practice.

  • In this study, we presented two geometric tasks to three 11th grade students to identify the characteristics of the images that the students had at the beginning of problem-solving in the problem situations and investigated how their images changed during problem-solving and effected their problem-solving behaviors. In the first task, student A had a static image (type 1) at the beginning of his problem-solving process, but later developed into a dynamic image of type 3 and recognized the invariant relationship between the quantities in the problem situation. Student B and student C were observed as type 3 students throughout their problem-solving process. No differences were found in student B's and student C's images of the problem context in the first task, but apparent differences appeared in the second task. In the second task, both student B and student C demonstrated a dynamic image of the problem context. However, student B did not recognize the invariant relationship between the related quantities. In contrast, student C constructed a robust quantitative structure, which seemed to support him to perceive the invariant relationship. The results of this study also show that the success of solving the task 1 was determined by whether the students had reached the level of theoretical generalization with a dynamic image of the related quantities in the problem situation. In the case of task 2, the level of covariational reasoning with the two varying quantities in the problem situation was brought forth differences between the two students.

  • Consider the situation that informations necessary to solve a certain problem are distributed among processors on a network. It is called a distributed algorithm that in this situation each processor exchanges the message with adjacent processors to solve the problems. This paper proposes a distributed algorithm to solve the problem that constructs the weighted shortest path tree in an asynchronous network system. In general, a distributed algorithm is estimated by the number of messages(message complexity of the distributed algorithm proposed in this paper are O(n53) and O(nln) respectively. where n is the number of processors on the network.

  • The object of this paper is to give an overview of one method of modeling and analysing situations involving inter-identification. Hypergame analysis is used as this approach. Hypergame analysis is one of what we call soft system approaches. In this paper, We first reformulate concept of the simple hypergame and define the hypergames with inter-identification as a system consisting of simple hypergames connected by the mutual identification. We propose a definition of solutions for them. Based on the formulation, We derives existence conditions of the solutions. We then apply the framework to a realistic problem. i. e, America-North korea conference problem to demonstrate the validity of the derived theoretical results as well as In obtain some suggestions to improve the problematic situation.

  • Scheduling problem in Flexible Manufacturing Systems(FMS) is complex because of various situation of Manufacturing Systems. Especially, in case of short-term scheduling demanding high efficiency, low cost at short-period, efficient scheduling is a serious problem. To solve this problem, many dispatching rules are developed. But, it leave much to be desired, because real situation in shop floor is complex and real-time scheduling is needed in real manufacturing shop floor. In this paper, search algorithm that allocate different dispatching rules to each machine is presented to complement lack of dispatching rule and develop practical real-time scheduling system. The search algorithm is described in detail. First, algorithm detect machine breakdown, evaluate each dispatching rule. dispatching rules for each machine meeting performance criteria are ranked. The algorithm selects new dispatching nile for bottleneck machine. The effectivenes and efficiency of the mixed dispatching rule and search algorithm is demonstrated.
