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.

分解理論의 알고리즘 分析

Large linear programming problems usually have some special structural form that can be exploited to develop efficient computational procedures. One common structure is where there are a number of separate activity areas that are linked through common resource constraints. Each activity must meet internal requirements that do not interact with the constraints of others; But in addition there are common resources that must be shared among activities and theredy represent linking constraints. A problem of this form can be solved by Decomposition Principle, which can be derived as a special version of the revised simplex method. The method is an iterative process where at each step a number of seperate subproblems are solved. The subproblems are themselves linear programs within the separate areas. The objective functions of these subproblems are varied from iteration to iteration and are determined by a seperate calculation based on the results of the previous iteration. This action coordinates the individual subproblems so that, ultimately, the solution to the overall problem is solved. In this method, the subproblems correspond to evaluation of reduced cost coefficients for the main problem. Discussed here are the mathematical background and the Algorithm of Decomposition Principle and implemented its calculational procedures by an illustrative solution.

Syringoadenoma papilliferum occurs as a solitary lesion appearing usually on the scalp. It's origin is not definitely known, and about one-third of cases are associted with nevus sebaseous. We describe a case of syringoadenoma papillferum associated with nevus sebaseous in a 29 year-old female who had developed bean sized verrucotic nodules on the Rt. temporal area of the scalp since 6 years after removal of nevus sebaceous. Histopathologic findings showed hyperkeratosis, acanthosis and villi that projected into a cystic lumen. And the villi were surrounded by two cell layers.

In large space such as a gymnasium, the supplied air is heated by air handling unit in winter. In that case the heated air goes to the upper area. We used the nozzle fan in order to improve the indoor air distribution, and the air flow characteristics and the temperature fields in the space are analyzed by computer simulation.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

The Korean isolates of porcine reproductive and respiratory syndrom(PRRS) virus, KPRRSV-1 and KPRRSV-2, were studied on the aspects of pathogenicity in the experimentally infected piglets. The piglets inoculated intranasally(in) with the virus at 10^4.5TCID_50/㎖(GroupⅠ) showed clinical signs of milder fever, respiratory disorders, anorexia, growth retardation and transient leucopenia. It was evident that the virus could be transmitted by contract. Histopathologically interstitial pneumonitis was markedly noted in the lung of all infected piglets. In studies on antibody responses of the experimental animals, seroconversions were noted at 6∼9 days pe in GroupⅠ(in inoculated) and at 12∼15 days pe in Group Ⅱ(contract). The antibody titers at 30 days pe were ranged from 256 to over 1024. By avidin-biotin immunofluorescence(ABIF) assay, the PRRS virus antigens were detected in bronchi, bronchiol and alveolar epitheliums and interalveolar septa of the experimentally infected piglets. The viruses were recovered from the tissues of lung and spleen of the infected piglets.

It is ten years since the volume based waste free system carried out. This aimed to analysis and estimate about the achievement of the volume based waste free system of the Ministry of Environment and Damyang-Gun. According to the analysis of its result, it is still unsatisfied to use the plastic bags of the volume based waste free system and to separate and throw away the wastes. The Public Opinion says that the Government needs to further step up publicity activities on the volume based waste free system by making good use of TV, newspaper, and magazine, and should offer the incentives to people who observe the volume based waste free system, In addition, it says that people in Damyang-Gun incinerate illegally(60.5%). Therefore. the study and supply of waste disposal method is necessary to people in Damyang-Gun, manufacturers themselves should collect wastes, and Damyang-Gun should expend the systematical device of collecting wastes. If these things go on, the volume based waste free system will be fixed.

During the past three years, the antimicrobial susceptibility for the major pathogenic bacteria isolated from the swine herds and dairy farms located in Chungchong area has been examined. The major bacterial species isolated from the respiratory lesions of the diseased pigs during the periods were B. bronchiseptica, Haemopilus spp, P. multocida, Streptococcus spp., A pleuropneumonia. And from the fecal specimens of the pigs with diarrhoea, E. coli, Salmonella spp., Campylobacter spp., Streptococcus spp. and Clostridium spp. were isolated and investigated for the drug susceptibility. The major isolates from the milk samples of the dairy cattle with mastitis were Staphylococcus spp., Streptococcus spp., E. coli, Pseudomonas spp., Corynebacterium spp., Clostridium spp. and P. multocida. The total of 311 isolates were examined for 24 kinds of antimicrobial drugs. Of the isolates from the swine respiratory lesions, B. bronchiseptica and Haemophilus spp. showed 83% to 92% of suscepibility to ciprofloxacin(CIP), amikacin(AN) and norfloxacin(NOR). The isolates of P. multocida revealed 80% to 90% of susceptibility to AN, CIP, NOR and gentamycin(GM) and all of A pleuropneumonia isolates, susceptible to AN, CIP, GM, kanamycin(K), NOR and sulfamethoxazole-trimethoprim(SXT). Of the isolates from the pigs with diarrhoea, most isolates of E. coli showed the high susceptibility to AN, CIP and GM. And Salmonella spp. revealed 71% to 94% of susceptibility to GM, cephalothin(CF), AN and CIP, Campylobacter spp., 79% to 95% of susceptibility to AN, CIP and GM, and all of Clostridium spp., to AN, CIP, GM and information(FM), Of the isolates from the dairy cattle, Staphylococcus spp. and Streptococcus spp. showed 81% to 95% of susceptibility to AN, CF, CIP, FM, and AN, CIP, SXT, FM, K, respectively. E coli isolates showed 81% to 94% of susceptibility to CIP, AN, FM, and Pseudomonas spp., 83% to 94% of susceptibility to AN, AM and CIP. Campylobacter spp. and Clostridium spp. showed 89% and 100% of susceptibility to CIP, respectively. In measuring the MIC range of the major isolates for the drugs showing high sensitivity, the isolates from swine showed ≤0.06-64 ㎍/㎖ in CIP, 0.06-128 ㎍/㎖ in NOR and 0.5-256 ㎍/㎖ in AN, and the pathogens from the dairy cattle, ≤0.06-128 ㎍/㎖ in CIP, 0.25-256 ㎍/㎖ in AN and 0.12-512 ㎍/㎖ in NOR.
