This paper presents a method for precisely localizing and parking of bimodal trams. In order to gain an automatically driving system for bimodal trams, precise up-to-date localization, velocity recognition, distance to next station and precise parking location estimation functions are required. This paper proposes a system consisting of control device, steering device, sensor input equipment, driving system, tachometer, vehicle-side sensors, magnetic markers and magnetic sensors. The tram recognizes the precise location via magnetic markers containing information. Parking position and precise distance calculation is embodied by a tachometer. The vehicle-side sensors are used to assure safe station approaching and parking magnetic markers provide improvement of precision while tram parking. This paper provides a system realizing localization and precise parking and afterwards the automatic drive test results are reported and analyzed.

Objective : The aim of this study was to analyse the latest trend of medical science articles about Bojungikki-Tang published in Japan. Methods : We searched medical science articles published from 2003 to 2008 in Japan on the web site, CiNii and then these articles were reviewed and classified according to experimental subject and method. Results : Fifty-two articles, related to Bojungikki-Tang were searched and these were classified into three classes, pharmacological signaling studies, clinical case studies and the others. As a result of classification, clinical case studies were most abundant by 38 cases, pharmacological signaling studies were 10 and the others were 4. This result suggested that the study of Bojungikki-Tang was mainly focused on clinical study rather than experimental study. Among the clinical case studies, clinical studies related to immune disease took the most greatest number and number of other clinical studies were evenly distributed over the various disease. Immune intensification effect of Bojungikki-Tang can be thought continuous with reinforce the middle Jiao Qi in company with improvement effect on growth hormone failure and male infertility. A fact that the one prescription, Bojungikki-Tang could be used to treat various diseases reflects a viewpoint of Oriental medicine that is based on the respect for and understanding of individual constitution and disposition while paying attention to the gender difference and individuality. The clinical usefulness of Bojungikki-Tang on obstructive sleep apnea syndrome and visceroptosis concerns with ascend Yang and treat Qi sinking. Pharmacological signaling studies were mainly focused on diseases that were treated Bojungikki-Tang in clinic, however, there was one study that experimented on changes of numerous gene expression according to the treatment of Bojungikki-Tang using DNA array. Conclusion : The therapeutic system of Oriental medicine is different in various aspects form that of Western medicine and appropriate harmonization of east and west is expected to improve the quality of medical care. In this regard, continuous investigation and analysis about herbal medical science papers in Japan can also be useful to make progress in Korean traditional medicine.

In this paper, we investigate the approach to estimate VaR under the transformed GARCH model. The time series are transformed to approximate to the underlying distribution of error terms and then the parameters and the one-sided prediction interval are estimated with the transformed data. The back-transformation is applied to compute the VaR in the original data scale. The analyses on the asset returns of KOSPI and KOSDAQ are presented to verify the accuracy of the coverage probabilities of the proposed VaR.

The level of hygiene practices varies depending on a variety of factors. The purpose of this study was to evaluate the level of hygiene practices performed in the contract foodservice establishments based on several variables, and to also determine the possible effects of each variable on the performance level of hygiene practices. We surveyed 215 contract foodservice establishments, excluding school facilities, managed by a large-scale contract foodservice company. The survey used a formulated sanitary checklist to evaluate the level of hygiene practices performed in the foodservice establishments. The sanitary checklist consisted of a total of 52 items in all 6 categories including personal sanitation and process control. The collected data underwent a series of analyses such as frequency analysis, ANOVA, and correspondence analysis of means using SPSS. from the results, we found significant differences among groups in categories such as the existence of a person in charge and types of business. A higher foodstuff cost had a tendency to correlate with a higher performance level for sanitary maintenance, but there was no significance on a statistical level.
