This paper describes design and implementation of a Web-based information service that supports management and retrieval of use cases for earth-related materials in traditional Korean construction process. Managed data are gathered from old traditional books which are written in Chinese characters. Development needs to consider providing users effective interface to retrieve information from the service easily. Gathering and analysis of earth-related data are processed in parallel to the database construction. Data store and management needs to be flexible enough. This paper introduces several design and implementation issues for the developed service, and proposes solutions for the them.

Functional recovery after mandibular condyle fracture was a contradictory result of many authors. The treatment goal of condyle fracture has been directed primarily toward restoration of functional movement of the mandible. We selected some patients who requested functional therapy in many cases of condylar fracture, depend on pattern of fracture, patient's demand, occlusion, age. Without intermaxillary fixation, we induced the patients to rapid healing of temporomandibular function and normal mandibular protrusive, lateral movement as a result of early functional therapy by activator. So, the authors report the cases with review of concerned literature.

The aim of this study is to develop a technique for keyword extraction in Korean-Chinese text in the modern period. We considered a Korean morphological analyzer and a particle in classical Chinese as a possible method for this study. We applied our method to the journal "Sisachongbo," employing proper-noun dictionaries and a list of stop words to extract index terms. The results show that our system achieved better performance than a Chinese morphological analyzer in terms of recall and precision. This study is the first research to develop an automatic indexing system in the traditional Korean-Chinese mixed text.

This paper proposes an algorithm for off line recognition of handwritten characters, especially effective for large-set characters such as Korean and Chinese characters. The algorithm is based on a minimum distance dlassification method which is simple and easy to implement but suffers from low recognition performance. Two strategies have been developed to improve its performance; one is multi-stage pre-classification and the other is candicate reordering. Effectiveness of the algorithm has been proven by and experimet with the samples of 574 classes in a handwritten Korean character catabase named PE02, where 86.0% of recognition accuracy and 15 characters per second of processing speed have been obtained.

The underground living spaces have become one of the major environment of this decade in urban area. This study was carried out to examine contamination level for purpose of preservation of the pleasant underground environment. Three subway stations and three underground shopping centers in Seoul and two underground shopping centers in Busan were selected and surveyed by measuring gaseous pollutants $(SO_2,\; NO_2,\;CO,\;HC,\; HCHO,\;CO_2)$, dust, airborne microbes, and the other air condtions (temperature, humidity, air pressure, air flow, kata cooling power). These examined data were compared with four kinds of standard (building sanitation management, room air quality standards, occupational safety and health standards, ventilation equipment) as environmental hygiene.

In this paper, we propose an on-line recognition system of chinese characters using an adaptive resonance theory-1(ART-1) neural network. Strokes, primitive components of chinese characters are usually warped into a cursive form and classifying them is very difficult. To deal with such cursive strokes, we use an ART-1 neural network that has the following advantages: (1) it automatically assembles similar patterns together to form classes in a self-organized manner: (2) it directly accesses the recognition codes corresponding to binary input patterns after self-stabilizing; (3) it doesn't tends to get trapped in local minima, or globally incorrect solutions. A database for character recognition also dynamically constructed with generalized character lists, and a new character can be included simply by adding a new sequence to the list. Character recognition is achieved by traversing the chinese datbase with a sequence of recognized strokes and positional relations between the strokes. To verify the performance of the system. We tested it for 1800 daily-used basic chinese second per character. This results suggest that the proposed system is pertinent to be put into practical use.

Choropleth map is a type of thematic maps in which areal units are shaded with a color or pattern that symbolizes some characteristic of the mapped unit. CMS was first developed to produce choropleth maps on ordinary microcomputer environments in 1988. Since then there have been significant technological developments and enhancements in user environments, which have affected the field of choropleth mapping systems posi¬tively. A new version of CMS was developed in accordance with these changes. CMS II requires an IBM PC, or compatible, with the minimum 640KB memory and VGA graphic board. It supports HP laser jet printers to output a high resolution map. The program can use Hangul letters for main menu, map title, and legend. And dBase file format (DEW) was implemented to exchange attribute files effectively.

An especial attention for old tunnel safety is required on increasing of The various tunnel recently. Specially, the lining investigation method of the old tunnel will be able to presume condition of concrete lining indirectly. Because it is many restriction thought of environment and ground condition investigation method of tunnel lining rear. This study carried out section & convergence measurement of part which was deformed in tunnel lining. It had been observed for the change of tunnel behavior with a continuous measurement. It has been analyzed for a cause of tunnel deformation and inspected for the effect after a repair-reinforcement to tunnel compared with the effect before those by structure analysis. By establishing automatic measurement system after repair-reinforcement to tunnel, it would be accomplished to convergence measurement continually. As a result, it was observed that deflection and deformation of tunnel was convergent. but it should be followed to a continuous maintenance because of unstable ground condition, cause of inner tunnel, environment. The railroad tunnel which was executed a reinforcement of the tunnel lining must investigate the close condition of reinforcement lining and concrete lining.

This article analyzes the record structure, content designation, and the content of UNIMARC, USMARC, and KORMARC formats for authorities, through the comparative investigation, Structure and content designation are almost same with those of the bibliographic formats, being based on those of ISO 2709. The data fields of USMARC and KORMARC are divided into blocks based on the traditional authority card formats, and those of UNIMARC are divided into functional blocks based on the GARE. Record contents of the formers in the fixed-length fields include more elements on the selectioa status and scope of the heading, and those related to the series. And those of the later include more elements for the international exchange. Based on the analysis of the variable fields, it is recommended that KORMARC should include an additional subfield, say $(\blacktriangledown\;j)$ for the processing of the Hanja(Chinese character) data and add the separate classification fields for series.

본 연구는 국내산 돈육의 Staphylococcus aureus에 대한 오염도와 항생제 내성 여부를 살펴보기 위해 실시되었다. 가공전의 원료육과 가공후의 포장육의 Staphylococcus aureus 에 대한 오염도를 비교해 본 결과 원료육에서 11.5%, 포장육에서 6.1%의 검출률을 보여 도축단계에서의 오염으로 판단된다. 돈육에서 검출된 Staphylococcus aureus의 항생제별 내성은 Penicillin 및 Ampicillin에 각각 93.3%로 매우 높은 내성률을 나타내었으며, Tetracycline에서 60.0%, Tobramycin 20.0%, Erythromycin, Streptomycin에 각각 13.3%의 내성률을 보였다. 2001년 전국 6개 도시의 일반인의 비강으로부터 분리한 S. aureus의 tetracycline에 대한 내성률은 8.2%로 돈육에서 검출된 S. aureus의 내성률과 비교하였을 때 7배 이상 높은 것을 알 수 있었다. 생산성을 향상시킬 목적으로 동물에게 항생제를 처방하고, 사료에 항생제를 첨가하여 균 자체의 내성율을 높이고 이런 균들이 인간에게 전파되어 내성균의 생성 루트가 될 수 있기 때문에 향후 돈육의 사료에 첨가하는 최초 항생제의 사용량부터 지속적인관리가 필요하리라 판단된다.
