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.

B site substituted mixed oxides LaCo_(1-x)Cu_xO_3(X=0, 0.1, 0.3, 0.5) were prepared by citrate sol-gel method in air, 850℃. By the thermal gravimetric analysis(TGA) and XRD analysis all of these oxides were single phase perovskite of rhombohedral structures. A as the amount of substituent increases, the amount of oxygen decreases and the lattice volume increases. Oxygen stoichiometry and lattice parameters of these oxides are as follows. LoCoO_3.0(a=5.44, c=13.10 Å), LaCo_0.9Cu_0.1O_3.0(a=5.44, c=13.2 Å), LaCo_0.7Cu_0.3O_2.92(a=5.46, c=13.14 Å), LaCo_0.5Cu_0.5O-2.84(a=5.45, c=13.27Å) According to the TPR results, LaCoO_3 and LaCo_0.5Cu_0.5O_2.84 undergo two-stage reduction stages, but LaCo_0.9Cu_0.1O_3.0 and LcCo_0.7Cu_0.3O_2.92 undergo three stages. The first reduction reaction of these oxides is one electron reduction reaction(oxygen 0.5mole). Reoxidated oxide in air at 1000℃, LaCoO_2.94 shows oxygen defect but the TPR result is similar to that of as-prepared oxide. By the reaction kinetics, the activation energy of LaCo_09.Cu_0.1O_3 is found to be the lowest value among those of the substituted oxides LaCo_(1-x)Cu_xO_(3-y).

The AIMS(Anima1 Infectious Disease Data Management System) was developed to collect and analyze data on animal infectious disease outbreak (62 diseases). When an animal infectious disease is confirmed at a diagnostic laboratory, the disease outbreak is then reported to the regional government through AIMS. After the regional government confirms the number of animals infected or dead, outbreak date and etc, this information is reported to the Ministry of Agriculture & Forestry and the National Veterinary Research & Quarantine Service through AIMS. The AIMS analyzes the outbreak data and reports the outbreak statistics by region, month and year to them. In addition, the AIMS can identify the farm where there was an outbreak of the animal infectious disease. There are four user roles : 1) Administrator, responsible for the overall operation of the system. 2) Inspector, responsible for confirmation of the animal infectious disease outbreak. 3) Pathologist, responsible for input to an animal infectious disease at first. 4) Gallery, only able to read the outbreak statistics. The AIMS has been implemented using the ASP technology and is operated on the web to allow easy access. The data, middle and presentation tier are based on MS-SQL 2000 server, Microsoft transaction server and Internet Explorer, respectively. The database's stored procedure was used to improve the performance. In addition to above software, the dextupload software is used to upload the files. By using the AIMS, a more accurate statistics for the animal infectious disease outbreak is expected.

In case of an apartment house, the application of LC(Life Circle) design that considers remodeling and reconstruction when the a house reaches a certain time after its erection needs to be reviewed for longevity from time series life perspectives that set up a period of durability for components and maintains and improves their performances through systematic replacement and repair. Apartment houses are constructed with parts of different sizes and life. It is important to manufacture materials and components with high durability. However, more importantly, well-thought-out and systematic plans are needed between parts with a space module and a life module and construction space. Hence, this research sought to investigation of the expected service life of parts or members according to repair or replacement cycles with social and functional aspects, considering the establishment of housing parts hierarchy through the analysis of expected service life. Consequently, the establishment of the repair cycle and estimation of the service life of housing parts have the remodeling in place in the frontline construction business and cut cost on remodeling, thus activating remodeling.

This study was conducted to examine health behaviors in hypertensive patients and the factors that would affect these healthy life-styles, and to provide basic data for effective and continuous hypertension control in private medical facilities. Among those patients diagnosed as hypertension who had visited the Department of Internal Medicine of Yeungnam University Hospital during the two month period from August 2 to September 30, 1999, the present study included 222 patients who were in more than one month after the initial diagnosis of hypertension and those who had hypertension for less than 10 years. Using a structured questionnaire, the present study was conducted by a self-administered survey method, and the obtained data were analyzed with t-test, χ2-test and one-way analysis of variance using the SPSS statistical program. The scores on knowledge related to hypertension were higher as the education level of a patient was higher(p〈0.05). As for occupation, those who performed office or management jobs showed higher scores than those who were into manufacturing jobs, and as for economic status, although those patients who were in middle class showed highest scores, however, no statistical significance was observed. The scores of knowledge on hypertension was higher when the family history hypertension was present(p〈0.05). The scores of health-related behaviors were higher with higher education level and higher economic status, higher in those with family history of hypertension, and higher in those with office or management jobs than those who had manufacturing jobs(p〈0.05). Blood pressure measurement on regular basis was performed most frequently in those who were between 50∼59 years old with 83.3% and was least frequent in those who were older than 70 years old with 50%(p〈0.05). The frequency of regular blood pressure measurement was higher with higher education level, higher economic status, higher in those with family history of hypertension, and the highest in those with management position with 93.5%, however, on statistical significance was observed. Changes in health-relaxed behaviors after hypertension diagnosis were higher with higher education level, higher economic status, and in those patients performed office or management work. In particular, diet change was observed in female and higher economic status and smoking cessation was observed in 60∼69 years old. Housewives and office workers or managers have taken exercise more regularly and those who had management jobs and had high scores on knowledge related to hypertension would participate health education program more actively. Thus, for improving health-related behaviors for continuous management of hypertension, changes in health-related behaviors can be followed through conduction health education to improve understanding of knowledge related to hypertension as the method of helping to improve changes in health life-styles in those with little education and those in low economic status.
