In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

The experiment was performed to clarify the effect of temperature on pulp during impression taking with modelling compound, alginate and plaster of paris. Mongrel dogs were anesthetized with nembutal, 30mg/kg body weight. In order to measure the pulpal temperature, an inserting hole was prepared on the cervico-labial surface of each canine tooth and a thermister probe (diameter in 23 gauge) was inserted into pulp chamber and connected to a carrier preamplifier (Narco Biosystem Co.). The change of pulpal temperature during impression taking was recorded on the physiograph that had calibrated under standard temperature. The impression was taken with modelling compound, alginate and plaster of paris by using the temporary aluminum crown. Alginate was mixed with 10.0℃ and 20℃ water and plaster of paris was also mixed with 20℃ water as a routine method. The obtained results were as follows : 1. Taking the impression with modelling compound, temperature rise of pulp was 4.85±1.31℃ and normal temperature of pulp was 33.2±1.15℃. 2. When impression taking was prepared by using the alginate mixed with 10.0℃ and 20℃ water, decrease of pulpal temperature was 3.01±0.89℃ and 2.14±0.71℃, respectively. 3. When plaster of paris was used as an impression material, time to maximum change of pulpal temperature was not significant.

Ordinarily stow net fisheries was used by floater beam and sinker beam for the purpose of spreading the mouth of net. But it was not only iuconvenient and dangerous but much defective. In this thesis, we have studied fundermental experiment of the improved stow net fishing gear using head rope, ground rope and otter sail instead of floater beam and sinker beam. From the result of this experiment, it has been succeeded for fishing work to achieve basically without any difficulty. The results obtained in this study were as follows. 1) The resistance of fishing gear was estimated R≒7V2 as possible as it is taken greatly. (R: Resistance V: the rate of current) 2) The interval of otter sail was spreaded smoothly. Being in normal condition, it was maintamed the width 37-38m. It was heared comparison with net mouth of ordinary gear, and the shearing force was enough. 3) The height of mouth was lower than we have anticipated to and seemed to have the supplement of buoyancy. But according to increasing the rate of current, the lowness of mouth height was little affected. 4) The height of otter sail was decreased at the rate of 30% by the rate of current, on the contrary, the height of wing was not decreased owing to sufficient buoyancy, 5) The adjustment of extention length of hanging wire(connected with fishing boat) and raising wire(with otter sail) was great important problem and it must be dealed with the most moderatly because of a corelation between the spreading of fishing gear and catching ability. 6) On the depth of 30m, it was taken 25 minuits to cast anchor and lines, 20 min cast net, 24 min haul net, 45 min haul lines and heave anchor, respectively. 7) The improved stow net with otter sail was cleared up the defects and difficult problems in ordinary gear using floater beam and sinker beam, and it have more advantages of fishing work than ordinary one. But there were involved in lots of problems in details to solve in the future.

The purpose of this study is to analyze the mental forms of Taekwondo players who attended 97. National contest. For this study, Loehr ' s(1982) mental power guestionair was used into 180 men and 164 women in the view of sex, school background, prize career and practice career. The conclusions are like the followings. 1. Analysis result between men(n=190) and women (n=164) was meaningful in the confidence factor, visualization, image factor and Taekwondo control factor. 2. Mental form analysis result of high school players(=180) and University players (n=164) was meaningful in intention control factor, image and visualization(P<,05) high school players showed higher grade in intention control factor than male University players, but vice versa in image and visualization. 3. In the comparison of superior players(n=162) with inferior players(n=188), superior players showed more meaningful difference in confidence factor, visualization, image and attitude control factor than inferior players statistically. 4. In the comparison of practice career (under years(n=92) 5-7 years (n=108) over 8 years (n=154), the factors that showed increased grade as much as practice career were confidence factor, visualization, image factor, active energy factor and attitude factor, but not in disenchantment level, intention control factor and motivation factor. Applying ANOVA, confidence, intention control, image, visualization factor and attitude control factor showed meaningful difference(P<,05, P<.01)

Mineral analyses of water samples from several areas of the Mankyung River and the Dongjin River regions in Chonrabukdo where dental fluorosis was observed, which had been conducted between June in 1978 and January in 1979, have shown the following results. In general, the mean calcium concentrations were high in the areas where the mean concentrations of phosphorus and fluoride were low. And in the same area where dental fluorosis was particularly observed, seasonally a few minerals were variable─namely, calcium, phosphorus, and fluoride. Those samples of high fluoride concentration have higher phosphorus concentration, but calcium concentrations were the opposite phenomenon. Particularly, fluoride concentrations were remarkably greater during the cold season(January) than during the rainy season(July).

The purpose of this dissertation is to study the system of moral philosophy reflected in the works of the Chinese philosopher Jang Hoingger, (A.D. 1020-1070), one of the six sages of the Song dynasty. In particular, the thesis focuses on studying the ethical implication in Jang Hoingger' mind theory. There were many investigations on Jang Hoingger philosophy from a various perspective for that time. Example for, there were the studies on the moral philosophy, the changing philosophy, the gi(氣)philosophy, and so forth. But there dosen't seems to be many thesis to approach Jang Hoingger' mind theory from the ethical viewpoint. Jang Hoingger' mind theory involves the moral elements. Especially, his void mind(虛沁) and his enlarged mand(大心) contain a strong moral property. His void mind(虛心) is a moral objective and his enlarged mind(大心) is the way to get it. Therefore, I researched the ethical implication in them by considering his mind theory from a moral philosophy.

These studies were performed in an effort to elucidate the relation between dental fluorosis and several minerals which are contained in drinking water in the regions of the high fluorosis index. The water samples were collected from several regions around the Mankyung River in Chonrabukdo where high fluorosis index was observed in the pupils and from the control regions where dental fluorosis were not reported. The contents were analyzed by means of spectrophotometry for phosphorus, fluoride ion activity for fluoride, and atomic absorption spectrophotometry for calcium, magnesium and manganese. The calcium concentrations of drinking waters collected from the regions where high degree of dental fluorosis was appeared were lower than those of control regions. The phosphorus concentrations in the regions of high fluorosis index were very high, and the fluoride concentrations were remarkably greater than those of control regions. There was regional change in the magnesium concentrations of drinking water collected from the regions of the high dental fluorosis and control regions. But manganese concentrations showed markedly high regional variation.

This experiment was performed to elucidate the reported anti-cariogenic effect of capsicum in rats. Streptococcus mutans strain B-13, which was drived from human oral cavity and known to be cariogenic, was cultured in TYG with water-extract of capsicum. Glucose content of water-extract of capsicum was also determined by glucose oxidase method. The results are as follows. 1. Glucose content of water-extract of capsicum was 25.6 (±0.5) %. 2. In logarithmic phase, water-extract of capsicum group showed less steepness in growth curve than control group. 3. In early stationary phase, size of bacterial cell mass was in order of control, 0.5% and 1% water-extract of capsicum group. 4. It appears that water-extract capsicum might contain inhibitory substance to growth of Streptococcus mutans B-13, in spite of its high glucose content.
