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.

We performed a prospective study of 303 transferred patients(21.8%) to our emergency center from their initially visited hospitals for 6 months from July 1992 to December 1992. The results were as followed; 1) One thousand three hundred eighty eight trauma patients were visited to the emergency center for 6 months. Among the transferred 303 patients, 99 cases were due to traffic accident, 72 cases were falling down injury, and 62 cases were blunt trauma injury. 2) In terms of injury severity score, patients who were directly admitted to our emergency center had a score of 2.51±5.39, while those who were transferred had score 4.53±6.24. The scores were statistically significant. The combined patient population had a injury severity score of 2.95±5.64. There was no statistical difference between the severely injured patient group (ISS>=16) and the less severely injured patient group(ISS<16). 3) Among the patients who were transferred to our emergency center, those who were discharged from initially visited hospitals within 1 hour had ISS of 3.56±5.70, while those were discharged over 24 hours had ISS of 5.27±4.37. But there was no statistical difference between two groups. 4) Of the 303 patients who were transferred to our emergency center, 265 were from Seoul and Kyung-Gi Do and 38 were from various other regions. Among the transferred patients who were brought to emergency center after at least 24 hours of their accidents, 30 patients were elective transfer(patients` need)while 25 were not-elective transfer(further evaluation or proper treatment). Within this group, 3 were severely injured patients, of them two expired. 5) Severely injured patients(ISS>=16) occupied only 15 cases(4%)among 303 patients who were transferred to the emergency center. Among them 10 patients expried at the emergency center. The causes of death were irreversible shock in 4 cases, intracranial problem in 4 cases and hypoxia due to airway obstuction in 2 cases. In the cases of transferred patients there were no interhospital communi-cation before transfer. From the above information, we conclude that the tansferred patients to our emergency center had a higher ISS than of those who directly visited to the center. For effective treatment and higher survival rate, interhospital communication, presence of medical personel during transfer, performing of basic life support prior to transfer and strict limitations for transfer except critically-ill patients are important.

This paper reports an investigaion for the health status of subway workers in the 67 subway stations in the Seoul area during from September 15th to Nobimber 15th, 2002 . Prevalence of subuective complaints was surveyed of 400 subway workers applied by a general health questionnaire-the Todai Health index(THI). The basic tool employed in this present study was the THI which is modified Comell Medical Index(CMI) and was developed by Tokyo University Research Team in Japan, and had been used to evaluate manufacturing workers, iron workers and other workers by Kim(1979), Chung(1982), Lym(1987), Lee(1996) in Korea. The results were summarized as follows; 1. The physical and psychological complaints were much higher in the 20~29 age group than other age groups. 2. The physical and psychological complaints showed a high tendency of increased incidence in all items as length of service decreased, and the 3~5 years group was higher than less 1 year group with regard to the symptoms of Digestive(C), Aggressiveness(F), Nervousness(E). 3. The physical and psychological complaints showed much higher tendency in the station staff(S?S) group than other groups. 4. The physical and psychological complaints showed much higher tendency in the under station(Un.S) and upper station (Un.S) groups than other groups. 5. The responses of physical and psychological complaints by monthly pay showed much higher tendency in he income of 10.1~1.50 millions won group than other groups. 6. The responses of physical and psychological complaints by smoker or non-smoker showed much higher tendency in the smoker group than non-smoker group. Therefore, it can be concluded that the worker of subway studied was perceived as acceptable the importance of health status, and suggested that the goverment of related subway need to be effort to control the health of subway workers in environment of indoor.

Object : This study was conducted as part of the national project to standardize stroke diagnosis in Korean medicine. In this study, we aimed to evaluate the characteristics of acute stroke between heat pattern group and cold pattern group. Methods : We recruited stroke patients from 5 universities(Kyung-Hee University oriental medical center, Kyung-Hee University East-West Neo medical center, Kyungwon university lncheon oriental medical center, Kyungwon university Songpa oriental medical center and DongGuk university llsan oriental medical center) from April, 2007 until February, 2010. We diagnosed them and selected 463 heat pattern patients and 182 cold pattern patients. Results : We find that the risk factor of smoking, alcohol, diet(prefer to meat) are more associated with the heat pattern group. On the other hand, inflammation history in recent 3 months and diet(prefer to sea food) are more associated with the cold pattern group. RBC, Hg, Hct, TG, CK and Cl are more related to the heat pattern group. CPT, total cholesterol and HDL are more related to the cold pattern group. Tae-eum type takes high distribution of the heat pattern group, and So-eum type takes high distribution of the cold pattern group. Conclusions : This study provides evidence that the heat pattern group have more risk factor than the cold pattern group.

The goal of this study was to conduct a comparative evaluation of accident rates between yellow taxis and non-yellow taxis in order to know whether vehicle color contributes to reducing accident rate as expected in Gyeong-Nam province. For this study, 49 company's taxi accidents and enrolled number of taxis were examined from 1992. 3. to 1996. 2. by month. The main finding of this study was that significant difference existed in accident involvement rate between yellow and non-yellow taxis overall. Especially, it was concluded that low significant difference existed in wounded accidents, but significant difference existed in property damage only accidents. However, the effect of vehicle age was not considered to those relationships. According to this study, it was concluded that vehicle color contributed to reducing taxi accident rate in Gyeong-Nam province.

The purpose of this study is not only to establish models and methods for forecasting the demand of domestic air transportation passengers but also to provide useful data for forecasting the demand of air passengers through statistical test. The first step of this study was analyzing the demand of air passengers by using the gravity and the abstract models that generally used for city-pair travel demand studies. The second step was analyzing the demand of air passengers by using the multinomial logit model that calculates the split rate of each mode by using travel service variables. And the estimated air passengers by these models and the observed air passengers were compared. The third step was estimating the changed modal split that caused by introducing the High Speed Rail. In order to estimate the change, the Pivot-Point Method was applied. The results of this study are as follows: - The statistical significance of the gravity model is not high enough. - The statistical values of the abstract and the logit models are significant, but the logit model is more realistic than the abstract model, based on estimated values. - It is estimated that the air passengers of Seoul-Pusan and Seoul-Taegu routes may be decreased by 88% and 90% respectively by introducing the High Speed Rail.

From ride share aspect, Korean taxis are functioning as public transit. However, taxi-operators are generating social problems on issuing taxi licenses every year, because there is no reasonable method for estimating adequate number of taxis in a city. Thus, a method for estimating adequate number of taxis was developed in this study, the method consists of three criteria; one is the criterion based on optimal taxis' occupancy rate considering optimal waiting time of passengers, the optimal income of operators, and working hours of taxi divers, another is criterion on taxi-passenger chane, the other is the criterion on traffic conditions. Also, a new observation method of taxis' occupancy rate was suggested. In this study, Chinhae was selected as the study city. Followings are the results of this study. First, by using the new observation method of taxis' occupancy rate based on taxi traffic count reliable occupancy data could be collected with low expenses. Second, the results applying the model suggested in this study to Chinhae showed that preset number of axis is adequate and the results matched well with the real situation of Chinhae.

Analogical learning은 문제를 해결하고 학습하는 하나의 효과적인 방법이다. 한 영역에서 또다른 영역으로의 관련성은 추론과 학습의 기반이 된다. 모델러가 이미 구축되어 있는 모델들을 제공받을 수 있다면 생산성과 이해용이성이 증가될 수 있다. 모델러는 부분적인 모델로 모델링을 시작하여 라이브러리에 저장된 유사하게 일치되는 객체 모델을 모델링에서 사용할 수 있다. 그것 또한 라이브러리에 저장된 객체 모델의 재사용이 된다. Analogical agent는 객체 또는 프레임워크를 이용하여 라이브러리를 브라우징하고 몇가지 유사한 모델을 제공한다. Analogical learning의 결과로는 객체모델링과 어플리케이션 영역에 익숙하지 않은 사람도 모델을 쉽게 구축할 수 있고, 객체모델링에 대한 그들만의 패권도 가질 수 있다. Analogical learning is an effective way of human problem solving and learning methodologies. The relation from one domain to other domains is the base of reasoning and learning. If modeler could be supported with previous constructed model, the productivity and understandbility can be improved. Starting with partial model, modeler can preserve it with analogically matched object model stored in a library. It is also the reuse of object model stored in the library. analogical agent accept the partial object or framework and browse the library with analogical matching function and provide several analogous model. As a result of analogical learning, novice to object modeling and application area can construct the model easily and they easily and they can have their own pattern for object modeling.
