Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive 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 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.

Verrucous mycosis fungoides is very rare variant of cutaneous T cell lymphoma that manifests verrucous crusted lesion and may be clinically misdiagnosed as a wart, deep fungal infection or atypical mycobacterial infection. If it is located acrally, it might then be better classified as mycosis fungoides palmaris et plantaris or pagetoid reticulosis. We report a case of solitary verrucous mycosis fungoides on the left knee in 25-year-old woman successfully treated ultraviolet A-1 phototherapy.

The purpose of this study was to evaluate effects of smear layer and dentin primers on the sealing ability of root canals. 126 extracted human teeth with single, straight canals and mature apices were used. The Samples were first classified into six groups as follows : presence of smear layer; absence of smear layer; Scotchbond Bond Multi-Purpose; All Bond 2; Mac Bond 2; Clearfil Liner Bond 2. A Positive control was also established. All teeth except the control group were then obturated with thermoplasticized gutta-per-cha and AH26. Electrochemical and dye penetration technique were later used to evaluate the degree of microleakage through the root canal. Seventy teeth were then immersed in a 1 % potassium chloride solution and An external power supply(DC 10 V) was then applied to the circuit for the electrochemical microleakage test. The degree of Microleakage was determined over period of 28 days before being evaluated. In total, 48 teeth were submitted to the dye infiltration technique. All specimen were suspended in 2 % methylene blue dye for 1 week before being longitudinally split. The degree of dye infiltration was measured under a stereomicroscope at×10 magnification and evaluated. The results were as follows: 1.Apical microleakage increased throughout the test period in all group and one group having a smear layer showed a dramatic increase under electrochemical test (p<0.05). In the group having smear layer, the degree of apical microleakage was the highest, and the microleakage was much higher than in the smear layer removed group in electrochemical test (p<0.05). Scotchbond Multi-Purpose, All Bond 2, Mac Bond 2 and Clearfil Liner Bond 2 showed lower microleakage than one group having smear layer. The All Bond 2 and Clearfil Liner Bond 2 treated groups showed the lowest microleakage in electrochemical test (p<0.05). 2.There was no significant difference between the experimental groups in dye penetration technique. These results suggested that the removal of the smear layer from root canal and concomitantly the application of dentin primer into root canal could improve the sealing ability of root canal obturation, 1

A theoretical study was carried out on the prediction of drop size distribution of the pressure swirl atomizer. Drop size distribution was obtained by using maximum entropy formalism. Several constraints in the form of the definition of mean diameter were used in this formulation in order to avoid the difficulties of estimating source term. In this study D10 only was introduced the formulation as a constraint. This drop size obtained by using linear Kelvin-Helmholtz instability theory was considered as an unknown characteristic length scale. As a result, the predicted drop size distribution was agreed well with experimental data measured with Malvern 2600.

Agglutination inhibition effects on Phaseolus vulgalis L. (P. vulgalis) was carried out with 1,223 of human sera and various sugars to understand serological characteristics of Panphytagglutinin, P. vulgalis. And demonstrated that the agglutination activity of P. vulgalis were inhibited by some sera but not by the others, and was designated the former as P. vulgalis inhibitor (PVI) and the later as P. vulgalis non-inhibitor(PVN). Frequencies of PVI and PVN were tested on 324 sera of healthy males, 197 sera of healthy females, as well as on 702 sera of patients with various pathological conditions. There were no differences in the distribution of PVI and PVN frequencies between male and female, and among ABO blood groups. The distribution of PVI was 95% (493) and PVN was 5% (28) in 521 of normal control group. A high frequency of PVN was noted in sera of the patients with gastric ulcer (38%, Z score=2.4397) and gastric cancer (25%, Z score=2.6633). No appreciable difference was noted in the frequency of PVN and PVI among patients with Duodenal ulcer, Gastro-enteritis, Liver cirrhosis, Hepatitis, Cholecystopathy, Pneumonia, Pulmonary tuberculosis, Bronchitis, Myocardiac infarction, CVA, Hypertension, Diabetes mellitus, Leukemia and Panperitonitis

Fifty randomly sampled male students (mean age 19 years) at Jeonbug National University in Jeonju city served as subjects in this study. These students were divided into three groups of 5 endomorphs, 36 mesomorphs, 9 ectomorphs according to Heath-Carter's anthropometric method. The one hundred meter dash and 2,000 meter distance run were adopted to measure aerobic and anaerobic motor ability respectively. To determinethe relationship of somatotype to motor ability and the differences of motor ability among somatotype groups, statistical analysis were used. The findings of this study are as follows: 1. The mean somatotype of college freshman was ectomesomorph. 2. Low realtionships existed between the first components of somatotype and aerobic and anaerobic motor ability. 3. The second and the third somatotype components were not related to erobic and auaerobic motor ability. 4. There were significant differences between aerobic and anearobic motor ability among somatotype groups. 5. Mesomorphs were superior to other endomorphs and ectomorphs in track records.

In the preceding study we have investigated and analyzed the differences in the intellectual levels and in MMPI profiles of the sexual criminals. In this study we will comprehensively invesitigate the factors influencing the sexual crimes in the juvenile delinquents. The subjects in this study were 211 sexual criminals who were institutionalized to the Seoul Juvenile Detention & Classification Center. This sample was investigated and interviewed by clinical psychologist & psychiatrist. The major findings investigated from this study were as follows: 1) The age of sexual criminals or rape victims is typically from 16 to 18 & their occupations were students & factory workers. 2) 26.54% of the sexual criminals (65.22% of the child group who were committed sexual assaults under the 13s & 21.81% of the girl-adult group who were committed sexual assaults Over the 13s) revealed psychiatric problems. 3) 28.44% of the sexual criminals were in drunken state at the time of their act. 4) Group or gang rape (involving two or more rapists) were estimated to comprise up to 80% of all sexual criminal cases. 5) 82.46% of the sexual criminals were in close relationship with the juvenile delinquents 6) The sexual experiences of the sexual criminals(41.23%) were more than those of general school boys(15.1%) and the age of victims is older than that of rapist. 7) The socio-economic classes to which the sexual criminals belongs were the low or low-middle socio-economic classess. 8) 40.26% of the sexual criminals had no sisters. 9) 15.64% of the sexual criminals don't have their parent and these findings showed no significant differences from that of the normal or the other group. 10) The sexual crimes have taken place in the deserted areas (41.13%), the around dwelling houses(20.38%) & the interior of the house(16.59%). 11) 70.62% of the sexual crime occured from between 7 p.m. to 12 p.m 12) The occurrence of rape has nothing to do with the month or the season.
