Green Belt area was designated in 1971 for the purpose of offering dilightful life environment to the citizens by preserving nature environment and preventing indiscreet development of city and its sprawling. It is evaluated that during the past 20 years under the strict restriction and management, Green Belt area occupying 5.5% of all country is success comparatively. But Green Belt area brought the realistic problems about illogical assignment of area boundary line, leaving land alone, infringement to right of private proverty. So, the foundational counterplan to these problems come to be requested. On these view point, this study aim at rational management in Green Belt area. In order to rational management and use of Green Belt area, therefore, the study about this issue and evaluation of Green Belt area have to be continued. The author hopes that this study will contribute to those who study Green Belt area or land and carry out a policy of land, and so on.

The present study considers responses to the earth science topics of science-gifted students learning concentrated and cyber earth science discipline programs. For the study, questionnaire portfolios with Likert scale and opinion-writing items were used in the purpose of investigating above responses, and opinions by e-mail and discussion in visiting rooms on website were analyzed, additionalIy. From those portfolios, the gifted students show more or less responses between fundamental and advanced course ones. Although fundamental course students have strong participating wills, they represent difficulties in program items and work solving times. But advanced ones relative\y somewhat ease those difficulties. The students are interesting in actual and curious items including constelIation finding and field survey. And, they hope to instalI items similar to above tendencies in the programs. So, efforts considering above results for the courses would establish more effective learning strategies for earth science gifted students.

From six surface sediment samples in Do-am Bay, Jeonanm Province, a number of sponge spicules, a few of silicoflagellates, and some diatom frustules occurred. Of those sponge spicules, monaxons mainly composed of oxea, styles and so forth are dominant but other spicules of triaxon, tetraxons and polyaxon are very rare. While above siliceous micro-organism remains are concentrated in the sites of innermost and mouth in the bay, other sites are relatively low in the occurrences of the micro-organism remains. In addition, a few of dark silicoflagellate individuals which are mostly dictyochids are restricted in the innermost site of the bay. Above results indicate that the bay is a warm littoral environment with the rearrangement of sediments connected with topography, and influences by open sea are very weak.

Extracting from diatomaceous mudstones in the Hakjeon Formation of Hasongri area, Pohang, 100 individuals of Archaeospaheridium pachyceros, archaeomonad, and of Actiniscus pentasterias, actiniscid, were studied in the aspect of morphological variations, respectively. From the results of the study, Archaeosphaeridium pachyceros individuals showed wide variations in spine development and cyst body and Actiniscus pentasterias ones presented variations in ray arrangement. So, it is considered that some morphological variations would be re-examined in specific or infra-specific classification levels.

From the Neogene Hakjeon Formation in Songra area, 7 silicoflagellate species belonging to 3 genera occurred. Of the silicoflagellates, cruxoid and mesocenid individuals were studied in skeletal features with respect to classification aspect. In the results, Distephanus crux ssp. parvus and D. crux ssp. scutulatus were recognized. In addition, paleoenvironmental approaches were performed in the silicoflagellates in the area. In the study results, cruxoids and mesocenids of the area might have potential values in biostratigraphical and paleoenvironmental study. On the bases of silicoflagellate flora, it is inferred that sedimentary environments were highly energetic and scarcely influenced by surrounding landmass during the deposition of the formation.

Three diatomaceous mudstone samples for the morphological study of ebridians were taken from the Hakjeon and the Duho formations of the northeastern area in Pohang Basin. Eleven ebridian species belonging to nine genera were identified in the samples. On the basis of ebridian assemblages, above two formations are correlated with Middle Miocene in age. And, the re-examination to some taxa of Ammodochium cf. A. rectangulare and Ebrinula sp. are necessary in time interval. Ebridian individuals from the samples show many varieties including double skeletal, hypersilicified and/or lorica bearing ones in skeletal morphology. Of these varieties, hypersilicification is remarkable in ebridian skeletons from the samples. But the distinct hypersilicified skeletons in the samples are mainly restricted to some taxa which are triaenes of Hermesinella and Hermesinum and a triode species of Ebriopsis antiqua. Other ebridian taxa are lowly or not in hypersilicification level. So, it is considered that hypersilicification in ebridian skeleton is a kind of taxa-related morphological features.

From the Tertiary Yeonil Group distributed in Songra and Cheongha areas, the northern part of the PohangBasin, nine archaeomonad species belonging to two genera, and other three types of chryophycean cysts considered asstomatocysts, five endoskeletal dinoflagellate species belonging to three genera and eighteen ebridian species belonging toeleven genera were identified. Based on above siliceous microfossil assemblages, the Yeonil Group is corresponded to(in Central Japan) by its archaeomonad cysts. And, the group is correlated with the intervals of Actiniscus elongatus toMiddle Hermesinella conata zones in Southwest Pacific region and of Spongebria miocenica to Middle Hermesinellaschulzii zones in Vøring Plateau, Norwegian Sea, based on the ebridian assemblages of the group. From thechrysophycean cyst including archaeomonad, endoskeletal dinoflagellate and ebridian assemblages in the Yeonil Group ofthe study area, it is inferred that cold water masses dominated during the deposition of the group with occasional warmwater. The upper part of the group might be somewhat colder than the lower one of the group in depositional condition.In addition, minute chrysopycean cysts considered as stomatocysts suggest the influence of fresh or brackish water duringthe deposition of the group..........
