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.

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.

This study is prepared to introduce design quality improvement measures by the trend and cause analysis of design changes which have been made during operations of construction project for power plant. In this study, two types of analysis tool have mainly taken for the use of the improvement measures. One tool is the trend analysis to identify which action should be taken to cut down design changes. This is also useful to monitor whether project participant's endeavour for the action taken is effective or not, to the project performance and design quality improvement. The other is the cause analysis, by using cause and effect diagram, which is useful to identify main causes of the design changes and to establish the measures to reduce recurrence of the design changes.

As a part of environmental pollution prevention and resources recycling, the regeneration of waste tire has been largely contributed to national industry. But, the worker has been evaded this regeneration process by reason of the best mischievous process condition among 3D industries.So, the first, the process condition of regeneratingwaste tire was analyzed. The second, the equipment or system was developed for the improvement of working strength and environment. The last, researchers intend to solve these problems

Various Cu-Zr bearing monolithic amorphous alloys, exhibiting different stress-strain behaviors, were prepared to investigate the nature of the plasticity shown by theses alloys. Microscopic observation of the quasi-statically compressed Cu_(50)Zr_(43)A1_(7) specimen revealed abundant precipitation of nanocrystallites, while insignificant changes in the microstructure were observed from the Cu_(64)Zr_(36) alloy. Finite element analysis was conducted in order to better understand the role of nanocrystallites in an amorphous matrix on the plasticity of the amorphous alloy. The activation energies for crystallization of the amorphous alloys were measured and correlated with the plasticity of the amorphous alloys. Herein, we report for the first time that the origin of the plasticity of monolithic amorphous alloys lies in the activation energy for crystallization. (Received February 14, 2005)

Background: The earthquake, measuring 7.4 on the Richter scale, on the 7th of August 1999 in Turkey left forty thousand injured or dead and caused billions of dollars in damages. Our medical team treated 3362 patients with a total number of 3703 visits in the area of Yaloba city for 12 days from the 26th of August to the 7th of September. Method: We retrospectivery analyzed the patients' charts after the medical service. Results: we found that there were no gender differences in the patients. The average age was 35.6 years, with patients in their 30s and 40s making up 42% of the total patients. The average number of visits per day was 300, and major complaints such as headache was most common, accounting for 13.7% of the cases. Cough and sputum were the second most common, acconuting for 12.2%. back pains, skin diseases, and abdominal pains appeared frequently. Conclusion: Disaster-related injuries and illnesses vary according to the type of disater and the time from the onset. Therefore, appropriate planning and medical support are required and should be improved based on experience. Korean disaster plans should also be improved.
