A prototype computer program was developed which visualizes various kinds of geotechnical information using 3D object graphics techniques. The program integrates various kinds of geotechnical data such as surface geology map, boreholes data, geophysical data as well as man made subsurface structures. It also reads NGIS DXF map and generates digital elevation model from iso-elevation line layer of the DXF map. All the data are put into a 3D model as 3D objects. The created 3D model can be viewed and analysed in a interactive 3D way.

At present, 51 textbooks from 6 kinds are adopted at primary and secondary schools in Korea. According to results of content analysis related to soil animals, their bionomics and the ecological roles were mentioned limitedly in only one or two pages. Since mere 7 phyla and 24 kinds of soil animals have been appeared, it is demended that more of subjects concerning soil animals especially in relation to environment should be introduced in school textbooks near in the future.

This study surveys the mechanical properties such as bending and shear properties to the weight reduction rate of PET fabrics. For this purpose, 12 kinds of satin and 18 kinds of plain weave fabrics are prepared with change of the physical properties of weft yarn(T.P.M., density, and denier) The weight reduction rate was 0％, 12％, 25％, and 30％. Bending rigidity and hysteresis, shear rigidity and hysteresis were measured and discussed with theoretical values in relation with weft twist, yarn linear density, weft fabric density and weave structures.

Ganoderma naturally growing in Ch'ungch'ongbuk-do, Ch'ungch'ongnam-do, Chollabuk-do, Chollanam-do, Kyongsangbuk-do and Kyongsangnam-do was surveyed during 1982∼1984. Four kinds of Ganoderma, red, yellow, white and black were found. But two kinds of Ganoderma, purplish and blue, did not found.. Their shapes were kidney or round and other types. Of them red Ganoderma was about 95% in distributional frequency while white and black Ganoderma were very rare.

The weather charts made at November 1, 1905 that were supposed to be the first daily weather chart in Korea were found and the contents of them were described and investigated. They were consisted of three sheets of paper. The first sheet consists of 2 kinds of weather charts. The second one does 6 kinds, and the third one is a table where 51 stations' records are in it. The diagnosing method and the historical background of the charts were explained. Although it is slim, the possibilities of the other earlier charts than these are explained also.

To realize artificial device with sensing ability of the human skin, a mono-material tactile sensor with three sensing functions made of some elastic thin electro-conductive rubber sheet with eight latticed patch elements is proposed. This trial sensor provides the information of three kinds of model material characteristics such as thermal property, hardness property and the surface situation of materials by setting up three kinds of surface models as test materials. It can be finally expected to estimate unknown model materials by analyzing the data of the sensor.

As for the Elect-CAD, it was developed a design of the electricity equipment which did manually, a quotation, all kinds of bill writing in the program that Package anger became. Elect-CAD can easily write an estimate back by all kinds of bill writing and estimatic with a design at the same time, and maximization gets an efficiency of work done and can efficiently manage project, and it is a revolutionary program in a management plane.

We have investigated about kinds of the equipment according to use. They have many kinds of equipments, namely conductive cloths, insulated gloves, conductive shoes, insulated sticks, swivel boom, fittings and insulator cradles etc. We have suggested about use of equipments, basic functions and shapes.

Counters for the various kinds of bank notes require high-speed distinctive point extraction and recognition for notes. In this paper we propose a new point extraction and recognition algorithm for bank notes. For distinctive point extraction we use a coordinate data extraction method from specific parts of a bank note representing the same color. The recognition algorithm uses a back-propagation neural network that has coordinate data input. The proposed algorithm is designed to minimize recognition time.
