Background : In recent years, gonorrhea has been pandemic and remains one of the most common 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 Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : 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 45.5% in 1997.

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.

This study was conducted to compare the concentration of sulfur oxides and nitrogen oxides emitted from the household incineration facility in Taegu city before and after the adoption of garbage packing system. Their concentrations were measured by an automatic analyzing equipment(MCS 100) at Sung-Suh household waste incineration facility in Taegu city using the non-dispersion infrared absorption analysis method from January 1 to June 30, 1994 before the adoption of the garbage packing system, and from January 1 to June 30, 1995 after the adoption of the system. The means of daily maximal concentration and daily average concentration of the emitted sulfur oxides were 40.9±23.00ppm and 21.4±6.18ppm in 1994, and 75.7±59.43ppm and 22.0±8.95ppm in 1995, respectively. In 1994, the concentration showed a gradual reduction from January until June, but there was a marked variation in 1995. By the day of the week, both 1994 and 1995 showed the lowest figures on Sundays. In the multi-variable analysis of variance to nitrogen oxides, there was not a noticeable statistical figure by the year and by a day of the week, but there did exist a noteworthy difference among the monthly emission concentrations (p<0.05). The means of daily maximal concentration and daily average concentration of the emitted nitrogen oxides were 175.6±23.82ppm and 122.3±26.92ppm in 1994, and 143.7±16.57ppm and 100.2±25.85ppm in 1995, respectively. By month, the means of its daily average concentration was lowest in June, 1994 at 89.4±26.29ppm and 72.7±31.36ppm in April, 1995. By the day of week, there was not much variation, it was lowest on Saturdays at 116.6±24.74ppm in 1994 and on Wednesdays at 93.4±25.79ppm in 1995. In the result of the multi-variable analysis of variance, it was significant that there was a difference in the nitrogen oxides emission concentration between the by-the-year figure of p<0.05 and by-the-mouth figure of p<0.05. This result suggests that the adoption of garbage packing system may affect the emission concentration of emitted nitrogen oxides from household waste incineration facility.

The Synchronous reluctance motor is a sinewave ac motor and it has cylindrical surfaces on both sides of teh air gap. The stator is conventional polyphase ac stator, while the rotor has internal flux barriers shaped to maximize the ratio of d-axis to g-axis reactance. This paper presents the finite element analysis and parameter measurement of the synchronous reluctance motor(SRM). The model motor is a 3-phase SRM with the segmental rotor and its rating is 0.175kw. The torque characteristic is analysed by finite element method and compared with that from measurement.

Photonic band gaps(PBG) are investigated for cubic diamond composed of dielectric spheres and air spheres. It was found that PBGs exist in both cases. PBGs lie between the 2nd-3rd, 8th-9th and 14th-15th band for dielectric spheres and the 2th-3th band for air spheres.

Background and Objectives: Squamous cell carcinomas (SCC) of the uterine cervix arise from the carcinoma in situ developed in a field of atypical squamous cell proliferation. So, clinical significance of the cervical intraepithelial neoplasm (CIN) are widely accepted. The purpose of this study is to investigate the oncoprotein changes in the sequence of low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), keratinizing type of squamous cell carcinoma (K-SCC) and nonkeratinizing type of squamous cell carcinoma (NK-SCC). Materials and Methods: Immunohistochemical stains for anti-bcl-2 oncoprotein to 120 conized cervical tiussues or resected uterus specimens diagnosed as squamous cell lseions including 30 cases of LSIL, 30 cases of HSIL, 30 cases of K-SCC, and 30 cases of NK-SCC were done. The evaluation of the bcl-2 immunostaining was based on the percentages of the positive neoplastic cells. And statistical analysis of data for the relation between each lesion was performed using the Student t-test. Results: The average positive cell rate was 2.0%, 4.44%, 6.25% and 13.57% in LSIL, HSIL, K-SCC, and NK-SCC, respectively. Statistically, immunoreactive positive cell rate of NK-SCC was significantly higher than those of LSIL (p=0.007) and HSIL (p=0.031). But, there was no significant difference of immunoreactive cell rate between K-SCC and HSIL. Conclusion: These results suggested that bcl-2 may play a role in a cervical tumorigenesis and prognostic relationship with NK-SCC.

In this paper, harmonic expansion method(HEM) for analyze optical components which are necessary before the fabrication of optical circuit component and as its applications, using narrow-band spectral filter are studied. Also a narrow-band spectral filter constructed with a W-index optical waveguide is proposed and analyzed. The proposed filter offers a spectral width on the order of one nanometer, considerably narrower than that provided by a filter made of two step-index optical waveguides having the same transmission wavelength. The narrow spectral width is achieved by exploiting a relatively large slope difference between the dispersion characteristics of the W-index and step-index waveguides constituting the filter. The transmission characteristic of the proposed filter with peak transmission at 1550nm is calculated and compared with that of a corresponding filter made of two step-index waveguide filters.
