In considering the fact for the ancient Chinese prostitute from the ancient times to the Tang, Dynasty it was inconvenienced by not having unavoidably a detailed explanation say to the unprovided materials send limited time, but when we dimly looked around the general circumstances at that time, we could find that the words `ancient prostitute' had a different meaning from the contemporary feeling from the very first time. That is to day, the ancient [CHANG]mainly meant singing and dancing and did not mean such an action as today's prostitutes under the present conception. However, it was too difficult to get at the fact of a matter. Since there was a slave system in China, it could he a direct motive to originate easily a prostitute from the system that the female servants at the low social standing was utilized as a prostitute. Anyway, the ancient prostitutes originally doing, singing and dancing had their slave status and tile form was ,also transfigured complying with a, requirement of the. society following the ages, and in the Chunchu Dynasty trough Joo Dynasty except the poing that [YORO] Kwanju.ng made ill the palace was a public prostitute house operated by the office management, as it was almost same as the today's social prostitute, it is not an exaggeration to be the beginning of Chinese prostitute. Under the circumstances, as the followed prostitute form had been continually presented even after the Chunchu Dynasty Han Dynasty's public prostitute was the one, .and what is worse, in tile wi. Jin Dynasty it was developed ,as a, home .prostitute system held by an individual. Eventually, this tendency was greatly fashioned in the Tang Dynasty comperatively an economic and political settlement, and. at that time, it was a certain result From the Chinese conditions under the age's commercial development and individualism conception that a business private prostitute occupied by wine and woman was publicly existed, including the prostitutes cared privately and publicly. So, the Tang Dynasty's prostitute can be with the name and fact called as the beginning of today's one, and further we can fortunately confirm the fact that the prostitute deeply rooted from the earliest time in the Chinese society, as such prostitutes was already ,existed in the Tang Dynasty.

This experimentation is carried out through the control system of Six degrees of freedom fine motion mechanism as follow; (1). In the case that optional input function is put to the Six-degrees of freedom fine motion mechanism, it is confirmed that this all draws a circular motion in the range of l00Hz frequencies. (2). In the case of incidense of sine wave (1 KHz) near to resonance frequencies at the direction of X, Z to the Six-degrees of freedom fine motion mechanism the vibration of input caused small interference to generate.

박환규 한국체육대학교 1998 敎養敎育硏究所 論文集 Vol.- No.3
A Study fight with stone missiles is the oldest one of play cultures in Korea. The fights are identified to be dated back to Kokuryo, which were actually played from long ago. The incentives to the fights are as follows; 1. The fights were exercised as one of the magic activities to predict a rich or poor harvest. 2. The fights were practiced as matial arts by way of precaution against war and actual fightings. 3. The fights were performed as a part of new year customs in January and Tano festival in May. The fights were prevailed to predict a rich or poor harvest in ancient times, as a type of military actual fighting in Chosun Dynasty and as a social function of new year customs in January and May to the end of the Dynasty.

During radiological examination, exposure should be minimized, and there should be nounnecessary exposure. But, 93 out of 100 radiation workers who examine with the control room dooropen were identified. The purpose of this study was to investigate the effect on radiation workers bymeasuring the scattering ray, leakage ray with an active dosimeter during radiological examination withthe control room door open. Among the five tests frequently performed in upper hospitals, two wereidentified, chest and spine. To study the difference according to the equipment, Listem’s Analog andGemss-medical’s Digital Radiography equipment were used. Control room door opening angles of 25°,50°, 75°, 100°, Measurements were made by changing the conditions by setting the distance from thedoor to 25 cm, 50 cm, and 100 cm. It was measured 10 times and represented by standard deviation, andChest, both instruments measured values below the radiation control area. Spine measurement result25 cm, 100 degree A device 2,325±33.6 μSv w-1, D device 2,572±38.4 μSv w-1 maximum measurement, Theminimum value was measured at 100 cm 25 degrees A device 159±16.4 μSv w-1 and D device 325±27.6. Except for 5 of the 24 conditions, all of them exceed the radiation control area. As a result of the study, it canbe seen that the annual dose limit is exceeded by converting the unit of the maximum value to 128.6±1.92mSv y-1. As the distance increases and the opening angle of the control room door decreases, the scatteringray, leakage ray decreases. Considering the probabilistic effects recommended in ICRP 103, it isjudged that continuous education for radiation workers is necessary.

The strength formula of gears has been reported in International Gear Symposium (September 1974, San Francisco) But in this paper we have selected first gear material then cut, and examined the way of heat treatment on the site in line with the above stated-strength formula of worm and worm gear. Having no such a heavy duty hobing machine available to cut the gear of 25 module and 72 teeth, we had a rough cutting with a fly cutter made first, and then applied a fine finishing with the built-up hob. The result of measuring of the completed worm wheel was proved to be satisfiable, but few errors that were generated on account of lacking of large sized gear measuring instruments.
