Background : The epidemic of human immunodeficiency virus (HIV) or sexually transmitted infections (STIs) is an important public health issue in the worldwide. Therefore, we investigated the trends of the seroprevalence of HIV and, syphilis and the gonorrhea positive rates in Gwangju from 2002 to 2006. Materials and Methods : The results of laboratory tests for HIV, syphilis and gonorrhea were collected from five public health centers and 19 hospitals in Gwangju. The number of tested patients from 2002 to 2006 was 348,202 cases for HIV, 80,115 cases for syphilis and, 103,548 cases for gonorrhea. Results : HIV/AIDS infections have rapidly increased at public health centers and hospitals. Especially, most of newly HIV-infected people were patients on ambulatory care/hospitalization, and they were also found via preoperation tests and according to the clinical symptoms. The gonorrhea positive rates have gradually decreased by year while the syphilis infection rates have slightly increased from 2002 to 2006. Conclusions : We have to determine the reasons why HIV and syphilis infections, but not gonorrhea, have increases simultaneously by the year. These results should be helpful to create a more effective STD prevention policy and the treatment guidelines for the people in Gwangju in the near future.

The purpose of this study was evaluated for fluoride release of various kinds of glass ionomer filling materials to deionized distilled water, the fluoride uptake and the anticariogenic effect on the adjacent tooth after class Ⅱ restoration with glass ionomer materials. Ketac-Silver, Miracle-Mix and Dyract were used as restorative material for this study. Fluoride concentration released to the solution from discs made of the above mantioned selected materials were measured daily for the first seven days, and then weekly, on the on the 14th and the 21st day. After class Ⅱ restoration with glass ionomer materials, the amount of released fluoride absorbed by the enamel of the adjacent tooth, and the anticariogenic effect on it was measured and observed, respectively. The results can be summarized as follow : 1. The largest amount of fluoride was released in each group first day, and the amount decreased as time went on. Miracle-Mix released more fluoride than all of the other materials tested. 2. The difference in the amount of fluoride released by Groups Ⅰ and Ⅱ, Groups Ⅱ and Ⅲ, and Groups Ⅰ and Ⅲ was statistically significant(p<0.05), except that between Groups Ⅰ and Ⅲ on the first, second and third days. 3. The amount of fluoride absorbed by the adjacent enamel showed statistically significant difference each groups (p<0.05). The fluoride uptake of Group Ⅰ was greater than that of Group Ⅲ, and Group Ⅱ, greater than that of Group Ⅰ(p<0.05). 4. In comparing lesion depth, all experimental groups decreased lesion depth than control group (p<0.05). The decrease was greatest for Group Ⅱ and least for Group Ⅲ (p<0.05).

This study was carried out to investigate the optimal conditions for producing somatic cell hybrids of vegetables. The conditions investigated are enzyme concentrations and duration of treatment for isolation of protoplast, concentration of PEG 4000 for fusion of isolated protoplasts, and viability of isolated protoplasts and fused protoplasts. The results obtained are as follows: 1. The size of onion protoplasts which are isolated from white mesophyll tissue is 52.6μm. The size of welsh onion and nanking shallot protoplasts is almost uniform (about 45μm) but the size of tomato and potato protoplasts isolated from callus tissue is various(21 to 86μm). 2. The optimal conc. of enzyme for isolation of protoplasts in the mesophyll tissue of radish, chinese cabbage, welsh onionm, and nanking ahallot are 0.5% macerozyme and 1.0% cellulase. While the onion is 0.5% macerozyme and 1.5% cellulase. 3. The optimal duration of enzyme treatment for produced intact protoplasts were 4hr in chinese cabbage, 5hr in radish, 3hr in welsh onion, and 2hr in nanking shallot and onion respectively. 4. Isolated protoplasts from mesophyll tissus were fused easily and produced the hetero-karyon with 25-35% PEG 4000 in inter-or intraspecies, while protoplasts of tomato and potato derived from cell were not fused easily. 5. The isolated protoplasts were viable until 1-2 days duration of culture, after 3-4 days they were died. The fused protoplasts regenerate cell wall in 1-2 days, while cell division and morphological changes were not observed.

This study aims to find out the individual and structural variables in the determination of the wages of the sports center staffs, to analyze the precedent factors of the wage satisfaction(variables of job inputs, the variables of job characteristics, the comparisons with the objects compared, the variables of the organization characteristics), and to examine the effects of the wage satisfaction(welfare programs, the levels of wages, the increase of wages, the management of wages) on the indexes of the organization efficiency such as the will to leave jobs, the outcomes of jobs, the organizational committment and so on. The materials were analyzed by using the programs of SPSS/PC+11.0 and LISREL 8.30 by means of the covariance structure analysis. The results of the inspection of the hypotheses through these methods of the study and the analyses of the materials are as follows: First, the results of the comparative analyses of the satisfaction in respect to the individual and structural variables show that females, the older groups, and the married groups have higher satisfaction than males, the younger groups and the unmarried groups. And the higher positions produce higher wage satisfaction. The higher schooling and the longer careers produce lower wage satisfaction, whereas, in terms of the salary management, they show higher satisfaction. In terms of the experiences of leaving jobs, the groups with no such experiences show high wage satisfaction, and the groups with experiences of leaving jobs two times show the lowest satisfaction. In terms of the methods to join the companies, the groups scouted show the highest wage satisfaction and the groups employed by public examinations show the lowest wage satisfaction. Second, the analyses of the precedent factors affecting the wage satisfaction show that the higher awareness of the job inputs, the job characteristics, and the comparison factors with the groups compared show the less satisfaction with the levels of wages. And the higher awareness of the factors of the organizational characteristics show the higher satisfaction. The analyses of the effects of the wage satisfaction on the organizational efficiency show that the higher wage satisfaction has a negative relation with the will to leave jobs, and a positive relation with the outcomes of jobs and the organizational committment.

Objective: This study was designed to evaluate the efficacy and safety of tianeptine and sertraline in the treatment of patients with depression. Method: The study was done on the patients with major depression diagnosed by DSM-IV, who had aHamilton Rating Scale for Depression(HAM-D) score ≥ 14 on the first 17 items of the HAM-D. A total of 40 patients were randomly assigned to tianeptine group and sertraline group. Tianeptine and sertraline were prescribed to each group. 6 weeks of each medication was carried out after 7 days of drug excretion period. Evaluation using 17 item HAM-D, Montgomery and Åsberg Depression Rating Scale(MADRS), Clinical Global Impression Scale (CGI), and Covi Scale was done on the baseline and after 1 week, 2 weeks, 4 weeks, and 6 weeks. Regrding all side effects that had occurred during the period of our study such as their developed/disappeaed time, severitien, incidences, managements and results have been recorded. Results: A total of 30 patients(tianeptine group 15 ; sertraline froup 15) finished the 6 weeks of research. 37.5mg of the daily dose was regularly prescribed to the tianeptine group, the average amount of 64.0±22.5mg of the final daily dose was prescribed to the sertraline group. Total 17 item HAM-D scores, total points of MADRS and CGI showed significant decrease after 1 week in each treatment froup and continous decrease after 2, 4 and 6 weeks ; and no difference was found between tianeptine group and sertaline group in the antidepressant efficacy. Also there were no significant changes in vital sign, CBC, chemistry, and EKG in each treatment group. The common reported side effects of tianeptine were nausea(33.3%), epigastic distress(26.7%), dry mouth(20.0%), headache(13.3%) and those of sertraline were dry mouth (53.3%), headache(46.7%), nausea(33.3%), anorexia(33.3%). Conclusion: According to the results, tianeptine was effective in improvement of depressive symptoms and was well tolerated and safe in patients with depression.
