Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

High blood pressure has become a common finding in Korean population and a major public health problem leading to an increased mortality and morbidity in recent years. With this accumulating evidence has come increasing incentive to find safe and simple methods for preventing and controlling hypertension. Reduction of dietary salt has been advocated by some for such method. The effect of dietary salt intake to hypertension however is still not clear and it is a matter of controversy particulary on whether the method of reducing dietary salt would be effective in controlling the hypertension of the general population. The purpose of this study was to investigate this controversial matter by assessing the degree of association between dietary salt intake and blood pressure using the method of detecting salt recognition threshold in general population. A total of 680 rural and urban inhabitants were studied from June 1984 to January 1985. The result of study is as followings; 1. The relationship between salt recognition, threshold and optimal gustation of salt was observed to be high in pilot study with a correlation coefficient of 0.729 (p<0.001). 2. In hypertensive group, mean systolic and diastolic blood pressures (BP) were significantly higher in those having high salt recognition threshold (SRT) than those of low SRT. The same evidence could be observed neither in normotensive nor in total population groups. That is, in hypertensive group, the mean systolic BP for those of high SRT was higher than those of low SRT by 8.8 mmHg in male and 8.8mmHg in female, and the mean diastolic BP for those of high SRT was also higher than those of low SRT by 4.3 mmHg in male and 8.5mmHg in female respectively. 3. There was no significant difference in the prevalence rate of hypertension among those of high SRT compared with those of low SRT. 4. In multiple regression analysis using age, body mass index (weight/hight²), socioeconomic status, amount of alcohol consumption, amount of cigarettee smoking, family history of hypertensi no and salt recognition threshold as independent variables, the multiple correlation coefficients turned out to be from 0.36 to 0.47 indicating that these variables explain 13 to 22 percent of the variances of systolic and diastolic pressures. The variables showing relatively higher beta coefficients were age, body mass index and alcohol consumption in male, where as the body mass index, age and family history were the corresponding variables in female. The relationship of salt recognition threshold to blood pressure was turned out to be very low. These findings indicate that dietary salt intake would have a significant effect on blood pressure in hypertensive group (may include the salt sensitive individuals), while no relationship could be observed in normotensive group.

Pathological observations were examined after abdominal inoculation in 7∼8㎝ sized flounder (Paralichthys olivaceus) with 1X10^7 cfu/㎖ of Streptococcus faecalis. The infected flounder were clinically observed and weighed a fish body at 0, 5, 10, 15, 20, 25, 30 days post inoculation. In infected group, mortality were 70% and feed efficiency were 7.2%. In non-infected group, mortality were 10% and feed efficiency were 18.2%. Macroscopically, the significant lesions were characterized by protrusions and opacity of the eyes and ulcer of the caudal pecuncle. Histopathologically, the lesions were observed a degeneration. necrosis and inflammatory cells in muscle of the caudal peduncle and a degeneration and necrosis of the rod cells and detached retina from the black pigmented layer

The results from investigation for the physical, chemical and biological marine environments during the period from February 1989 to November 1990 in the Wando coastal areas are as follows: 1. The water temperature appeared high in proportion to a amount of diural sun rays and air temperature. 2. The salinity appeared differently every season by a amount of precipitation. 3. The distribution of pH was settled, and the degree of acidity apperared relatively high in the area where the river waters flows. 4. The dissolved oxygen was low in summer season, but high in winter. 5. The distribution of the chemical oxygen demand was distributed irregularly every season. 6. The suspended materials appeared remarkably high on St.1 in 1990. 7. The concentration of the phosphate-phosphorous is higher in river waters than in sea waters, and the phosphate-phosphorous in sea waters was mostly flowed from lands. 8. The concentration of the dissolved inorganic nitrogen appeared high in autumn when nitrite-nitrogen and nitrate-nitrogen is more concentrated. 9. The relative relationship between phosphate-phosphorous and dissolved inorganic nitrogen appeared higher comparatively in 1990 than in 1989. After all. our investigation suggests that the physical, chemical character brings about an abnormal variation of the marine ecosystem, and obstructs the birth and breeding of the submarine livings. Therefore, we must draw up divers shemes for the preservation of the quality of coast water, and concentrate our efforts on doing away with factors of all marine pollution which spread rapidly in proportion to the industrial development.

This thesis is a study on the folk dance of Korea on the basis of the folk dance theory of Europe, America and Japan. Especially the so-called Korean folk dance is analyzed and studied in its historical background, its origin and its philosophy. The discussion is focused on the subject of whether the Korean folk dance can be considered as a folk dance according to the general concept and the original characteristics of the folk dance.

The relative frequency and distribution of somatoatatin immunoreactive cells were investigated by the immunohistochemical method in the gastrointestinal tract of the Korean native cattle and goat. The results obtained were as follows: In the Korean native cattle, somatoststin cells were a few in the pyloric and duodenal region and rarely seen in fundic region, jejunum, ileum, cecum, proximal colon, central coil, distal colon and rectum. In the Korean native goat, somatostatin cells were the most numerous in the pyloric region and the next in the fundic region. And they were a few in the duodenum, not detected in the cecum and sparse in the jejunum, ileum, proximal colon, central coil, distal colon and rectum.

Pilomatricoma was histopathologically diagnosed in a 2.5-year-old male Alaskan malamute. The patient was referred to Chungnam National University, Veterinary Medical Teaching Hospital with solitary, firm and well-circumscribed mass at shoulder. Grossly, the mass was dome shaped to tumor like and 10 x 8 x 5㎝ in size. Some lesions had gritty or bony consistency and was chalky when sectioned Histopathologic feature included mumerous clusters of tightly arranged, basaloid cells with evenly distributed chromatin and ghost cells were characterized by a central unstained zone. The ghost cells often become calcified and osseous metaplasia was also present.

Recently, as the Smart Phone is rapidly disseminated worldwide, it is emerging as an important digital communication media changing the communication types of users. We use the Smart Phone in all aspect of daily life besides communication. The Smart Phone is indispensible tool that has a great ripple effect on our daily life. Therefore, if the Smart Phone users lose or do not bring their phones, they were troubled. In this paper, we make users available to use the Smart Phone, even if they lose or do not bring their phones. To do this end, we develop features that search the phone in case of not knowing where it is, that contact another phone in case of not bringing their phone, that lock the phone in case of losing it. We expect these features promote a expansion and a vitality of the Smart Phone market.
