The Usefulness of Panoramic Radiography in Human Identification / 대한법의학회지

Panoramic radiography, which can show dental characteristics in one film and evaluate postmortem information, may be highly valuable in human identification. The purpose of this study is to evaluate usefulness of human identification with dental characteristics shown in panoramic radiography through panoramic radiographies of 300 randomly selected patients who visited Yonsei University Dental Hospital. Dental characteristics of each film were classified into 8 types and diversity of dental characteristics was evaluated by turning the informations into codes. Diversity of panoramic radiography using both maxillary and mandibular dental characteristics was 99.58%. When mandibular dental characteristic (98.99%) was used alone, the diversity was found to be higher than that of maxillary dental characteristic (97.92%). Maxillary dental characteristics showed diversity in the order of right molars (92.32%), left molars (92.02%), and incisors (41.54%), while that of mandible was in the order of right molars (96.09%), left molars (95.70%), and incisors (18.97%). As a result, human identification using panoramic radiography proved to be useful not only when the whole teeth are present but also when only molars are present. Therefore, it is expected to be applied more economically and practically in identifying a large number of victims from mass disasters as well as wars.

A Case Study of Constructing a Medical Web-Casting System / 대한의료정보학회지

As digital technologies develop further, computer and communication networks combined more and more. In addition,the integrated systems of broadcasting and communication accelerate the disappearance of business borderline between them.Intemet broadcasting technology such as Video on Demand(VOD) system is a good example. There are also digitized, two-way communication systems such as web-casting, satellite and cable communication networks In order to get better information more effectively in the modern society, the authors needed to actively deal with multimedia contents provided by new media system, such as video-conferencing, distance education, Internet broadcasting, and things go on.This was the way to satisfy customers desire for better services in medical area. Consequently, it became possible to practice telemedicine, including distance medical examination and treatment, counseling, and education. The updated networksystems using ISDN, optical lines, microwaves and multi-channel satellite can be utilized for a video-conferencing system to support an effective telemedicine. In order to establish and execute national information policies effectively, it is requiredthat the laws, regulations, and the organizations related to broadcasting and communication matters need to be modified.The purpose of this paper is to suggest a model of a medical web- casting system with high cost-effectiveness. This has been supported by our experience in establishing an internet broadcasting system at a general hospital.
