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.

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.

The purpose of this research is make out construction specifications for International Construction. Using off-shore products incur cost increase and longer delivery term of construction. and inconvenient on International Construction. Expand the range of additional local products conforming to performance. Life Cycle Cost. maintainability. operability. user's acceptability, etc.. And this study is suggest the standard formats and the techniques for construction specification.

This study was carried out to examine the reducing ability of asbestos quantity added in asbestos reinforced cement composite(ARC). The using amount of asbestos is subject to restriction from 10-20 vol% to 5-10 vol%,because it is very harmful cancerogenic substance. Asbestos was replaced by pitch based isotropic carbon fiber, and then the mechanical properties, compressive, tensile and flexural strengths were tested as a function of mixing proportions. The results are as follows 1) The compressive strength of carbon fiber and asbestos reinforced cement composite(CFARC) was greater than ARC by superplasticizer, reducingW/C ratio to 20 percent. 2) The tensile strength of CFARC was showed increasing trend up to 52% compared to ARC at 5% carbon fiber volume fraction. 3) The flexural strength of CFARC was showed increasing trend up to 17% cowpared to ARC at 5% carbon fiber volume fraction.

If obstacle in power supply, its affects are great are on the community and it is consequently demanded lots of difficulties to recover and repair. Accordingly, diagnosis techniques, that are able to prevent from accidents before they happen by providing more stable and highly reliable power effectively and finding sign of the accidents, is very, important. A novel Ultra Wide Band microstrip-fed circular patch antenna i presented. The measured impedance bandwidth of the proposed antenna is from 0.5[GHz] to 2.5[GHz] with the stop band from 0.5[GHz] to 1.7[GHz] for VSWR<2. Form results of this study, The antenna is will play an important role for the sensor for insulation diagnosis system by UHF method of real site GIS and power equipment using SF_(6) gas.

In this study, the relation of discharge patterns with the radiated electromagnetic waves is investigated by measuring electromagnetic waves using a antenna and a spectrum analyzer. The patterns of radiated electromagnetic waves measured at the atmospheric pressure in Liquid Nitrogen(LN_(2)) during the partial discharges in nonuniform electric field depend on positive DC power. From these points of view, it is considered that these results obtained from this investigation may be used as fundamental data for diagnosis and prediction of insulation on the equipments of superconducting and cryogenic applications.
週40時間 勤務制가 專門建設 活動에 미치는 波及 影響 分析

From July 2004, the 40 hours workweek system has been introduced to the construction industry. So, if the introduction of the 40 hours workweek system is unavoidable, then we need to have preparations against negative effects from that system because the construction industry has several characteristics as obstacles to settle down the system. Therefore we should consider several problems caused by them. The previous studies have been focused to effects of the 40 hours workweek system on the general construction industry. In order to analyze the effects of the 40 hours workweek system on the construction industry, it is essential to analyze the effects on the specialty construction industry because the actual construction activities are performed by the specialty construction companies. This study presents the effects of the 40 hours workweek system on the specialty construction industry. Therefore, this study tries on doing an in-depth analysis about the effects on specialty construction cost and time according to the introduction of the 40 hours workweek system.

Drilling process is usually used in various manufacturing processes. The burrs took place when drilling process is conducted. Therefore the burr problem occurred from drilling process is very significant. Sometimes, burrs cause unexpected problems such as no good quality product that has a good surface roughness. Therefore, it is important to know characteristics of burr formation and to remove the burr from the drilled material at machining process. This study aims that how to produce the better drilled products by controlling of process factors.

The purpose of this study is to set up the customer satisfaction management by presenting effective plan for human resource management of the hotel through analyzing relationship between internal customer satisfaction and employee job satisfaction. The suggestion of this study based upon the empirical analysis is as follows. First, communication factor among internal customer satisfaction factors is most effective factor on compensation & economic factor, organization & system factor, and working & environment factor. This means that enough communication between internal customers in hotel is communication in hotel has a had effect on employee job satisfaction. Second, hotel company should pay attention on internal marketing like policy of management, communication, and job support for employee job satisfaction. Third, hotel manager can understand easily about relationship between departments in hotel by finding out overall corporate mechanism on operational organization of the hotel, and management & attention on these departments are most important. This study focused on the relationship among internal customer satisfaction, employee job satisfaction, and customer satisfaction through internal marketing. Thus, mention for other parts were not enough and there were limited analysis on internal customer satisfaction factor of the hotel regarding employee job satisfaction. And the direct relation between internal customer satisfaction and customer satisfaction were not proved. Therefore, more comprehensive and precise study in factor and effect of internal customer satisfaction & employee job satisfaction in required.
