In this paper we discuss an application, the Local College Learning Management System (LoColms) , which we are developing, that is both sustainable and economical to suit the situation inthese countries. The application is a web-based system, and aims at improving the traditional form of education by empowering the local universities. Its economicability comes from the fact that it is supported by traditional communication technology, the public switching telephone network system, PSTN, which eliminates the need for packet switched or dedicated private virtual networks (PVN) usually required in similar situations. At a later stage, we shall incorporate ontology and paging tools to improve resource sharability and storage optimization in the Proxy Caches (ProCa) and LoColms servers. The system is based on the client/server paradigm and its infrastructure consists of the PSTN, ProCa, with the learning centers accessing the universities by means of point-to-point protocol (PPP) .展开更多

Vilage woods also function as wildlife habitat and promote agricultural biodiversity. Here vilage woods were classiifed in to four types （natural forest, semi-natural forest, half-natural forest and artiifcial forest） and 23 main tree species（dominant or sub-dominant species） identiifed.Pinus densilfora is dominant at 50 sites, and Zelkova serrata is dominant at 45 sites. Across village woods, emerged plants comprise 125 families, 519 genus and 1081 species. In spite of the extremely small area of village wood, 100 000 km2 or 0.00278% Korea’s territory, this ecosystem has an important biodiversity and habitat conservation function. Vilage woods are not only a base for conserving biodiversity, but also deliver ecosystem services in South Korea.展开更多
