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 purpose of this was three-fold: i) to investigate the degree of asymmetry in Angle's Class Ⅲ malocclusion patients and normal adults; ⅱ) to determine the nature of difference existed between two groups; and ⅲ) to investigate the correlationship between the degree of asymmetry and ANB and overbite in Angle's Class Ⅲ malocclusion patients. The subjects consisted of 25 Angle's Class Ⅲ malocclusion patients and 25 normal adults and the mean ages were 22.0 and 24.5 years, respectively. Their posteroanterior and lateral cephalograms were traced and analysed with three-dimensional approach. The results were as follows: 1. Asymmetry of Angle's Class Ⅲ malocclusion group was significant in all regions except cranial base. Their horizontal asymmetry was seen in mandibular angle, maxillary and mandibular midline and menton. Vertical asymmetry was observed in maxillary lst molar and mandibular shape and anteroposterior asymmetry in mandibular angle. 2. Nine variables indicating asymmetry were selected and each variable had similar discriminant score. 3. There was a little correlationship between ANB and asymmetric variable(MSR-B6) and its correlation coefficients was 0.3564. 4. There was no significant correlationship between overbite and asymmetric variables.

This study was to investigate the effect of horticulture therapy on the healing and rehabilitation of the mentally retarded (MR) and physical disorder (PD) persons. Horticultural therapy program was carried at S rehabilitation center located in Kyounggi-DO from Jun 29, 1999 to Oct 12, 1999. The participants in this program were 36 clients of MR and PD. They attended 14 times once a week for 1 hour at a time for horticultural therapy. Evaluation of horticultural activities and ADL (Activities of daily living) has been assessed two times, that is, before and after horticultural therapy program (HTP) whereas horticultural therapy group activity treatment procedure and horticulture task skill inventory have been assessed 3 times, that is, before HTP and after each 7 weeks. MR in the evaluation of horticultural activities showed statistically significant in participation, interest and assistance, verbal interaction during activity, self-concept and identity, need-drive adaptation, interpersonal and social relations, cognition and problem solving, exercise perceptivity, life-tasks skill and vocational adjustment. In activities group of MR also showed significant improvement in terms of physical perceptual abilities, cognitive ability, writing ability, social interaction (P<0.001). Additionally, their horticulture task skill were improved significantly in skill and efficiency factor (P<0.008) and their ADL were changed positively but not significant. On the other hand, PD in evaluation of horticultural activities showed significantly positive changes in self-concept and identity, interpersonal and social relations, life-tasks skill and vocational adjustment. However, physical perceptual abilities factor was proven to be effective in horticultural therapy group activities treatment procedure (P<0.002). Only grooming was significantly improved in ADL evaluation of PD (P<0.03). Putting these results together, it was found that horticultural therapy programs would be very useful for rehabilitation and healing method in both MR and PD.
