JOURNAL FREE ACCESSThis paper describes the relationship between the Internet and the information with a rural community. I make clear that there are four major fields of information with a rural community. These fields are; (1) Information about the history of the rural community; (2) Information about traditional recreation and enterainment; (3) Information about traditional events; (4) Information about the role of the community during a time of war. This kind of information is very beneficial to the Internet education for students and to the development of the community. However, many teachers have difficulties using personal computers and the utilization of the information is not effective yet. I analyze these problems using the method of principal component analysis and cluster analysis which are quantitative techniques used in the analysis of multivariate data. Consequentry, I classified teachers into three groups (clusters A, B, and C) based on the level of knowledge of personal computers. The information of the rural community is closely related to its education system which is supported by the Internet.View full abstractDownload PDF (1619K) -

JOURNAL FREE ACCESSA windows 95 based analyzing system for searching competitive production areas for vegetables and fruits was developed with Excel VBA, utilizing a vegetable-fruit information database “NAPASS”. This system contains several new functions in addition to all of the four analyzing functions implemented in the original system programmed by N88BASIC. This upgrade has brought several advantages for the efficiency of the system usability compared with the original system.View full abstractDownload PDF (2586K) -

JOURNAL FREE ACCESSIn the present study, the authors constructed a support system using virtual reality (VR) for plant factory design. To make and simulate a growth model, it is important to consider light conditions and plant arrangement during cultivation. Muskmelon plants were used as a growth model, and heliotropism was used as a characteristic of growth.
The system was composed of three units. The first was a CAD designed greenhouse. The second was a unit analyzing sunlight incidence in the greenhouse and the growth of muskmelon plants. The third was a VR that visualized a greenhouse and a plant object.
The authors tried to create muskmelon plant objects to confirm the validity of this simulation using the total number of leaves of a muskmelon plant and the light intensity as parameters. From these experiments, it was possible to recreate real shape of muskmelon plant objects in three dimensions. This system also showed that VR was effective to develop a sensuous easy to-understand system.View full abstractDownload PDF (1630K) -
-Detection of Cytoplasmic Strands by 3D Reconstruction of Image Data-T. KAMEOKA, A. Hashimoto1997 Volume 6 Issue 2 Pages 103-115

JOURNAL FREE ACCESSReconstruction of 3D image by using a plural photograph with the different focal length is often requested in the field of agricultural information research. As an example, an image processing system for 3D image display of cytoplasmic strands orientation in a cell was constructed.
In the present paper, the system used 4 microscope photographs of a single barley coleoptile cell taken at 10 μm intervals in depth and recognized automatically the indentical strands found in different photographs as a single strand in 3D, and finally displayed a 3D image of strands in a cell. By comparing the inforamation of strands with the results of cytoplasmic streaming obtained before, it was shown that cytoplasmic strands were oriented radially when cytoplasmic streaming was most active.View full abstractDownload PDF (1028K)
