  • This paper presents development of a classification system for an electrical fire investigation. In order to reduce an electrical fires and establish detailed prevention plans, the collection of an electrical fire causes and base data are very important. Based on this data, a new classification system for an electrical fire investigation was developed and the direction to the classification system was suggested by fundamental analysis. All of the collected information is analyzed by bottom-up method. Criteria items which based on base data were categorized to classify items. The classification of items were found out as follows : basic condition fire scene condition, fire sign, fire cause. Particularly, the fire cause category is classified. A new developed classification system for an electrical fire investigation will be used to analyse electrical fires easily and efficiently.

  • A flare from an Air Force fighter was abnormally dispensed during the landing. To determine the cause of the abnormal dispensing, fracture analysis, signal analysis and reproduction experiments based on physics of failures were performed. The primary cause of the failure was analyzed to be due to an intermittent fault of an internal circuit card in the AN/ALE-40 chaff/flare dispenser by a broken lid of a capacitor, and the root cause which had derived the primary cause was considered to be an improper handling during the domestic maintenance which were changed from the overseas maintenance due to the DMSMS problem. Therefore, the overall process of the maintenance capability development system was reviewed and alternative ways that considers maintenance error decision aid(MEDA) for system improvement were suggested to prevent further failures.

  • This thesis is based on a research to investigate the electrical fire risk due to the single and composite cause in a terminal block. This paper analyzed the thermal characteristics depending on the screw torque change and contact resistance change to measure the fire risk due to the poor contact from single cause first. To measure the fire risk due to the composite cause, the acceleration tracking depending on the contact resistance change was experimented to check the correlation of poor contact and tracking to fire. The experiment result showed that the thermal characteristics were clearer as the screw torque in poor contact status and magnitude of contact resistance increased and that the thermal characteristics of terminal block depending on the contact resistance change was more reliable than the thermal characteristics depending on the screw torque change. Moreover, the terminal block poor contact and tracking were correlated in the case of the composite cause, and when two composite causes were interacted, the electrical fire risk was higher than the single cause.

  • According to the literatual study on the Infantile Vomiting since the publication of ${\ll}Hwangjenaekung{\gg}$, the results were as follows. 1. The causes of vomiting are classified into the following kind: external cause are the cold and heat, not external and internal are disorder of food and mood, internal are the dysfuntion of spleen, stomach, liver, kidney. 2. The Oriental Medical cause of Infantile Vomiting is disorder of food, intusion of outside evil, heat accumulation in the stomach, deficiency of stomach liquid, reverse flowing of Qi resulted from fear and being frightened. There are so many causes of Infantile Vomiting, but they are all related to the stomach. 3. The Western Medical cause of Infantile Vomiting are classified with the situation of stimulation, age, accompanied symptom. The main cause related with the age is inhalation of amniotic fluid, maternal blood, infectious disease, wrong lactation method, functional and organic abnormality. 4. The Infantile Vomiting is similar with the adults, but the spleen and stomach of infants is so feeble that the vomiting happens very easily. The reverse flowing of Qi resulted from fear and being frightened and disorder of food are the main cause in infants. 5. The cause of Infantile Vomiting between Oriental Medicine and Western's is so similar and both emphasized the function of spleen and stomach. But the comment on the external cause(cold, heat) and not internal & external cause(mood disorder) is a creative view of Oriental Medicine.

  • Objectives The purpose of this study is to investigate the effect of Jihwangbaekho-tang on chest discomfort of unknown cause in a 52-year-old male patient diagnosed with Soyangin. Methods Patient had chest discomfort. But, the cause of this symptom was not identified by various cardiac examinations. The patient was treated with Soyangin Jihwangbaekho-tang for 2 weeks on the basis of Sasang Constitutional Medicine and the symptoms were evaluated by GAS(Global Assessment Scale). Results After using Jihwangbaekho-tang, GAS score has been decreased from 7 to 3. Conclusions This case study suggests that chest discomfort, whose cause is unknown, can be treated when using Sasang Constitutional Medicine.

  • The purpose of multiple alarm processing is to give the operator the correct information and perception of the malfunction present in the plant. In this thesis, an APS(Alarm Processing System) is studied for fossil power plants. This APS is based on a cause-consequence trees in the knowledge representation aspect for alarm and plant and adapts alarm filtering methods using fired time information in the decision aspect. Through the cause-consequence trees and filtering methods, the Alarm Processing System finds the cause alarm among the fired multiple alarms and calculates the cause degree which represents the possibility of a fault occurring in the instruments of the plant with the information of fired alarm. The knowledge base is built via interviews and questionaries with the expert operators on the Seoul power plant unit 4. Finally, the validity of the studied APS is shown via simulations.

  • This study is to define a congitive paradigm including a new model of common cause human behavior error domain and to analyze their causal factors and their properties of common cause human error characteristics in software engineering. A laboratory study was performed to analyze the common causes of human behavior domain error in software development and to identify software design factors contributing to the common cause effects in common cause failure redundancy. The results and analytical paradigm developed in this research can be applied to reliabbility improvement and cost reduction in software development for many applications. Results are also expected to provide training guidelines for software engineers and for more effective design of ultra-high reliable software packages.
