A medical image workstation was developed using multimedia technique. The system based on PC-486DX was designed to acquire medical images produced by medical imaging instruments and related audio information, that is, doctors' reporting results. Input information was processed and analyzed, then the results were presented in the form of graph and animation. All the informations of the system were hierarchically related with the image as the apex. Processing and analysis algorithms were implemented so that the diagnostic accuracy could be improved. The diagnosed information can be transferred for patient diagnosis through LAN(local area network).

In this paper, MIIS (Medical Image Information System) has been designed and implemented using INGRES RDBMS, which is based on a client/server architecture. The implemented system allows users to register and retrieve patient information, medical images and diagnostic reports. It also provides the function to display these information on workstation windows simultaneously by using the designed menu-driven graphic user interface. The medical image compression/decompression techniques are implemented and integrated into the medical image database system for the efficient data storage and the fast access through the network.

Hybrid optical-electronic procedures are introduced for the automated estimation of cell parameters (e.g., size, size variation, and shape). Two different optical Fourier analysis procedures are applied to high contrast cell boundary patterns obtained from specular micrographs of the endothelial layer. In one case, a large number of cell patterns are illuminated to extract average cell size information. Once the average cell size information has been obtained, individual cells are illuminated to extract shape information.

생물다양성정보는 크게 종(species) 정보와 내용(content) 정보로 나눠 데이터베이스화한다. 이때, 분야별 데이터베이스 통합은 종에 대한 횡적인 통합과 내용에 대한 종적인 통합이 동시에 이루어지며, 분류학자들에 의해 정의된 항목과 국제적인 GSD(Global Species Database) 구축의 표준이 되는 내용들을 기반으로 구성요소들의 표준화 정의와 XML기반 표준 DTD를 작성한다. 또한 분산되어 있는 데이터베이스를 대상으로 통합 검색이 가능하도록 Mediator기법을 적용하여 관리시스템을 설계하였다.

This study was carried out to obtain basic information for gene manipulation in potent edible tobacco (Nicotiana tabacum cv. TI 516). N. tabacum cv. TI 516 is a plant for a possible candidate to use as an edible vaccine, since it contains a low level of nicotine. The effective plant regeneration system through leaf disc culture was achieved using a MS basal medium supplemented with 0.1 mg $1^{-1}$ NAA and 0.5 mg $1^{-1}$ BA. In order to transform the N. tabacum cv. TI 516 with the green fluorescent protein (GFP) gene, Agrobacterium tumefaciens LBA 4404 containing the GFP gene was used. Genomic PCR confirmed the integration of the GFP gene into nuclear genome of transgenic plants. Expression of the GFP gene was identified in callus, apical meristem and root tissue of transgenic N. tabacum cv. TI 516 plants using fluorescence microscopy. Western blot analysis revealed the expression of GFP protein in the transgenic edible tobacco plants. The amount of GFP protein detected in the transgenic tobacco plants was approximately 0.16% of the total soluble plant protein (TSP), which was determined by ELISA.

본 연구는 숙주특이적인 근류형성에 두과작물의 뿌리분비물에 포함된 기주특이적인 flavonoids와 근류균의 상호작용에 대해 실험하였다. Flavonoid 화합물에 대한 근류균의 생물학적 활성은 B. japonocum의 경우 대두의 뿌리분비물에 포함된 flavonoid화합물인 daidzein과 genistein에서는 생장 증진 효과가 나타났으며, alfalfa의 뿌리분비물에 포함된 flavonoid인 luteolin에서는 생장 저해 효과가 나타났으며, R. meliloti의 경우 luteolin의 경우 생장증진 효과가 나타났으며, daidzein과 genistein의 경우 생장저해효과가 나타났다. 각 근류균의 흡수 특이성은 B. japonicum에서 daidzein과 genistein이 각각 $14.95\;{\mu}g/g$와 $14.20\;{\mu}g/g$로 가장 높고 luteolin이 가장 낮게 나타났으며, R. meliloti의 경우 luteolin이 $18.31\;{\mu}g/g$으로 가장 높고 daidzein과 genistein이 가장 낮게 나타났다. 이와 같은 사실로 숙주특이적인 flavonoids가 근류균의 숙주특이성에 깊은 관련이 있을 것으로 사료된다.
