Driving Behaviors in car-following are affected by not only the factors related to road structure, road environment and traffic condition, but also the factors related to drivers' cognition for visible Information. In this paper is to study the relation of drivers' cognitive response for visible Information that is speed and density. The experiments are tried that driving maneuvers are directly observed by video recorders sets on the vehicle and the driver is interviewed about his recognized degree of speed and density. And then, data obtained from this experiment is dealt together with numeral data of visual traffic condition to compare the difference among drivers and to derive the factors of drivers' cognition. As a result, the characteristics difference of cognition among drivers' is recognized.

In this paper the analysis is carried out with stated preference panel data. Increasing attention has devoted in recent years to dynamic analysis of travel demand analysis using data sets that consist of observations made on the same set of individuals repeatedly over time. The prevailing approach to demand forecasting is based on models estimated on cross-sectional data. This practice assumes that variations in stated preference observed across individuals within a cross-section can be extrapolated longitudinally to predict changes in each individuals stated preference over time. But changes in stated preference take place over time. In the paper's focus is the estimation of dynamic model. I incorporate serial correlation and state-dependence in SP dynamic model.

PVK와 TNF 사이에 형성된 전하이동 착물에 관한 연구(Ⅱ) : C. I. E 表色系에 의한 純度에 대하여 Purity by J.I.E color system

Thin films of solid state were made from solutions of organic polymers of different molar mixtures of poly-N-vinyl carbazole (P.V.K) and 2,4,7 -trinitro-9 - fluorenone(T.N.F). The donor, P.V.K. and the acceptor, T.N.F. molecules form a charge transfer complex. Meassuring the color purity of the thin films by using the C.I.E color system we found that the color purity of these polymers was increasing as the molar ratio varied from 1:0.2 to 1:0.6, 0.2 and 0.6 being TNF. This means that these organic polymers form a charge transfer complex up to the molar ratio 1:0.6. It was also found that this charge transfer complex can be classified as intermediatly interacting one by electrical property of these polymers.

"본 논문은 대한외과학회지 2006년 제70권제1호에 실렸던 논문으로 대한외과학회 편집위원회 승인을 득하고 본 협회지에 게재함. Purpose: Malnutrition has been frequently reported for patients on their admission to the hospital and it has been associated with an increase in morbidity, mortality and the length of the hospital stay. Although a number of screening tools have been developed to identify those patients at risk for malnutrition, there is no' gold standard' for defining malnutrition and the malnourished patients remain largely unrecognized. The aim of this study is to evaluate the efficacy of a nutritional screening tool for use in Dankook University Hospital. Methods Nutritional evaluation was performed for 53 patients who were admitted to the department of surgery and internal medicine between October and December 2004. The screening tool was completed by the ward nurse and the nutritional support team nurse on the same patients within24 hours of admission. The nutritional support team nurse performed the full assessment. The screening sheet included 4 questions regarding body mass index, recent unintentional weight loss, food intake and disease severity. Each answer was scored and a total of 5 was tested as the criterion fey malnutrition. The full assessment included current body weight, recent weight loss, triceps skinfold thickness, mid-arm muscle circumference, serum albumin)in and total lymphocyte count. Malnutrition was defined by 3 or more values below the reference values. The reliability of the screening tool was assessed using kappa statistic. Sensitivity, specificity and accuracy were calculated to evaluate the validity of the screening tool. The receiver operating characteristic(ROC) curve was drawn to choose a cutoff valve that maximizes sensitivity and specificity. Results' The level of agreement between the ward nurse and the NST nurse was good for BMI and food intake and moderate for weight loss and disease severity. The full assessment identified7 patients(13.2%) as malnourished. The screening sheet had a sensitivity of 86% and a specificity of 80%. According to the ROC curve, a score of 5 points provided the best validity. Conclusion The nutritional screening tool is reliable when completed by different observers and it is valid for nutritional assessment.

그룹웨어기술은 분산된 환경에서도 서로 가까이 있는 것처럼 대화하고, 함께 협력 하여 작업하며, 정보를 쉽게 교환할 수 있도록 해 주는 핵심적인 기술로 현재 많은 연구가 이루어 지고 있다. 본 논문은 공동 작업환경을 위한 효율적인 그룹통신관리를 독립적인 모듈로 설계하여 그룹웨어 응용시스템의 개발을 지원하는 플랫폼으로 이용하 고자 연구되었다. 논문에서는 우선 그룹통신관리를 위한 요구사항을 도출하기 위해 화상 회의와 같은 응용 개발 사례들을 분석하였으며, 공통적인 구조 및 기능적 특징들을 살펴 보았다. 아울러 그룹통신관리와 직접적으로 관련이 있는 표준화와 연구활동 등을 통하여 기본개념의 설정이나 / 설계시 고려해야 할 사항들을 점검하였다. 이를 토대로 기본적인 그룹통신관리 모델을 정립하고, 그룹통신관리의 구조와 처리절차를 설계하였다. 또한 인터넷 환경에서의 그룹통신에 필요한 dynamic하고 global한 주소화 방식을 구현하기 위하여 IP 멀티캐스트 주소와 포트 번호의 결정 방법에 대한 구조 및 방식을 제시하였다. 특히 멀티캐스트 주소는 먼저 회의 준비단계에서 계층분산체계의 주소관리자들을 이용 하여, 그룹이 포함된 도메인명치을 이용하여 중앙의 주소 관리자에게 지역 주소관리자의 주소확인을 의뢰하고. 그룹웨어 응용이 동작시 해당지역의 주소관리자에게 Initiator의 IP 주소를 제시하여, 이중 network 주소부분을 이용하므로써 주소가 실시간에 생성될 수 있도록 하였다. 아울러 신뢰성있는 데이타 전송서비스를 기술하고, 끝으로 설계검증의 한 방법으로 이미 개발된 응용서비스에 적용하기 위한 전체적인 시스템구조를 논의하였다. Advanced countries are very active in deploying the National Information I infrastructure which provides universal service to promise fruitful quality of futuree life. Even in the distributed environment, we can closely converse, work together, and share information in a very convenient way. This is actually enabled with the help of groupware technology, which are currently focused and researched in a larger popularity. The aim of this study is to design a portable pack for group communications management to support the development of groupware application. In the paper we begin with technical survey, continue to build our own model for group communications man agement, and design its architecture and procedure. We also suggest group addressing mechanism under Internet environment such as how to create IP multicast address and IP port number dynamically and as a globally unique value for the communication session, with the help of the hierarchical and distributed address managers. We also indicate the reliable data transmission services to remedy the unreliable feature of the UDP multicast services, and finally the architecture/ applied to support the practical applications is briefly discussed for verification of the designed concept.

The production of the entomopathogenic and phytotoxic cyclic depsipeptide beauvericin (BEA) was studied in submerged cultures of Fusarium oxysporum KFCC 11363P isolated in Korea. The influences of various factors on mycelia growth and BEA production were examined in both complete and chemically defined culture media. The mycelia growth and BEA production were highest in Fusarium defined medium. The optimal carbon and nitrogen sources for maximizing BEA production were glucose and NaNO3, respectively. The carbon/nitrogen ratio for maximal production of BEA was investigated using response surface methodology (RSM). Equations derived by differentiation of the RSM model revealed that the production of BEA was maximal when using 108 mM glucose and 25 mM NaNO3.
