The "Annals of the Joseon Dynasty (朝鮮王朝實錄)" is the precious historical material which contains royal culture of Joseon dynasty as an official document. It kept a record of the diseases and treatments relating to the 27 Kings for a period of 518 years, who had a variety of different symptoms. Among them the most frequent disease was a skin disorder such as a boil of a painful infected swelling. Dermatosis became the direct cause of death of several Kings. In this article we tried to conduct research using the "Annals of the Joseon Dynasty" into the skin diseases of the Kings during the first period of Joseon dynasty from the first King Taejo (太祖) to the 12th King Injong (仁宗). Among the 12 Kings, the 5th King Munjong (文宗), the 7th King Sejo (世祖), the 9th King Seongjong(成宗), the 10th King Yeonsangun (燕山君), and the 11th King Jungjong suffered from dermatosis. The King Munjong died at the age of 38 and suffered from severe boils before his death. The cause of death is thought to be septicaemia. The King Sejo does not have any specific record of skin disease, however, the recently discovered relics showed the indications of serious skin trouble of boils. The King Seongjong suffered from skin diseases at the age of 20, 27, 28 and 38. Nevertheless, the direct cause of death was not dermatosis. The King Yeonsangun had skin trouble of boils on his face when he was 20. He lost the throne and died of an infectious disease at 31. The King Jungjong had a record of suffering from dermatosis at the beginning of twenties, at the middle of forties, and at the age of 57 when he died. The skin trouble affected the whole of the body. He was treated with acupuncture therapy and medication for both internal and external uses among which folk remedies were included.

This study explained about the different motive of partner homicide and this homicide's elements which are feature of human sociology, home environment, school life and partner's trouble causes. After analyzed these element which affect to the motive of partner homicide, we couldn't find statistical differences of partner homicide motive by sex, having a job. However, there are small gap in an age group. Almost the homicide by expressive motive was a primary factor in the whole mass but, in the age of 40's, 11.1% is by the homicide of instrumental motive in the partner homicide. We need some more detail analysis and the partner murderer who growed up in very poor home circumstances commit Homicide by 100% expressive motive. This result suggested that murderer who was in the inferior home environment can do murder more easier than normal because of their emotional reason which are urgent, impulsive and contingent. On the other hand, their school life behavior during a growth process was useless for explain the motive of partner homicide. On one side, we could confirm that partner's trouble cause is a very useful element for explain the partner homicide, that is, if the if the level of conflict with partner's were high, the murder by expressive motive will grow up. But we must see the fact that the partner homicide's rate is 13.3% by instrumental motive in the low trouble causes very carefully for understand the partner homicide.

Fuel oil mostly used for a ship is made from crude oil by refining process. In order to produce plenty of high-quality fuel oil, the Fluid catalytic cracking(FCC) method is widely adopted to many refinery factories during the decomposition process from high molecule into lower molecule. The major constituents in spent FCC catalysts are Si, Al, Fe, Ti, alkali metals and some others. The spent catalyst is also composed small amounts of rare metals such as Ce, Nd, Ni and V. The big problem in FCC oil is mixing the catalyst in the oil. This reason is unstable separation of FCC catalyst in separator. Such a FCC catalyst will become a reason of heavy wear down in moving parts of engine. The impurity in oil is ash and deposit compound, such as Al, Si, Ni, Fe and V, which will accelerate the wear down on fuel pump, fuel injection valve cylinder liner and piston ring. It is important to find a basic reason of an engine trouble for preventing similar troubles anymore. Insurance compensation will be different according to the reason of an engine trouble which might be natural abrasion or other external causes. In this study, types and reasons of engine troubles related to fuel oil will be covered.

This paper deals with the formation and development of hierarchical ranking stmcture among universities in Korea and the nature of university education. As the growing number of university graduates have trouble with finding job opportunity, the development of skills and competency which are required for the labor market is becoming the most important role for universities. Finally, I proposed several policy suggestions to overcome negative aspect of hierarchical ranking structure of university.

The chassis of T.V, cassette, radio and telephone are made up thin-iron plates that makes a lot of female screws to assemble various parts. Then makes hole in the iron plate and forming female screws of burring face after the burring. Female screws forming in thin-iron plate is very difficult working then rolled forming process use of plastic deformation instead of cut forming. In this study goals are solve the trouble problem of industrial field and develop new model tap for prevent chips.

Voltage varing Fate dv/dt which is applied to induction motor usually makes unnegligible leakage current and it flows through stator winding and motor frame. This kind of harmonic leakage current makes effect on power source and cuases electromagnetic trouble because the motor frame has earth. Therefore in this study, a high frequency induction motor model is developed and analyze the motor performance to explain the phenomena. Inverter model is also developed and is combined with the motel model to prepare the basis of the high frequency effects on inverter fed induction motor.

Recently, GPS device is used in various industries. GPS can calculate a moving train's velocity, location, and direction. In this paper, we examine a train approaching alarm device's application, possibility, and merits in the train system. Especially, we investigate solubility of trouble caused by using GPS and RF system for detecting the train's velocity, the location and direction recognition.

When top down method is used, it could be a construction method trouble in column joint, between the former concrete and the latter. It could bring a void and weak concrete in column. The purpose of this study is finding a way to prevent concrete void and concrete suitable for top down, through V-metering for top down column and concrete experiment.

During normal operation of 100% FP Reactor power(TBN/GEN output:690MWe), several times of acceleration phenomena has been generated on the turbine generator-of Wolsong #1 NPP. It was concluded that the acceleration occured following big sudden drop of the terminal voltage of main generator due to AVR potentiometer fault. The cause of turbine acceleration is reviewed with a several records and demonstrated by computer simulation, also presents a countermeasure of its trouble.

Domestic automotive industry is also facing the moment it should be with a competitively priced and highly qualified automotive ta compete with worldwide automotive makers of world market through global marketing and global sourcing. At this point, weve been studying xNX model of USA, Japan and Europe with OEMs, suppliers and KAMA(Korea Automotive Manufacturers Association) to give a network infrastructure of guaranteed service quality network performance, reliability, security and trouble handling. We hope all efforts above mentioned will make the whole industry more competitive and powerful.
