This study was carried out to develop technologies of restoration and revegetation through monitoring the change of vegetation after setting up 3 type experimental sites on abandoned coal-mine lands. According to the results of 7 month's monitoring, sown species and a variety of invading species appeared at experimental sites. Moreover, the number of species, individuals and the ratio of coverage increased as time passed on. After 5 months, each experiment sites showed the result of successful revegetation. The most effective sites was treated by overspreading 1 cm loam soil on coal minesoil. As a result of this study, it is considered that the revegetation of abandoned coal-mine lands can be achieved effectively by making the minimum of foundation layer and improving the efficiency through mechanized construction. Besides, it is recommended to use native and early stage-succession species adapting themselves to coal minesoil, such as Gramineae, Leguminosae, Compositae and etc.

Austenitic stainless steel welds (ASSWs) of nuclear components undergo aging-related degradations caused by high temperature and neutron radiation. Since irradiation leads to the change of material characteristics, relevant quantification is important for long-term operation, but limitations exist. Although ion irradiation is utilized to emulate neutron irradiation, its penetration depth is too shallow to measure bulk properties. In this study, a systematic approach was suggested to estimate mechanical properties of ion irradiated 308 ASSW. First of all, weld specimens were irradiated by 2 MeV proton to 1 and 10 dpa. Microstructure evolutions due to irradiation in δ-ferrite and austenite phases were characterized and micropillar compression tests were performed. In succession, dislocation density based stress-strain (S-S) relationships and quantification models of irradiation defects were adopted to define phases in finite element analyses. Resultant microscopic S-S curves were compared to verify material parameters. Finally, macroscopic behaviors were calculated by multiscale simulations using real microstructure based representative volume element (RVE). Validity of the approach was verified for the unirradiated specimens such that the estimated S-S curves and 0.2% offset yield strengths (YSs) which was 363.14 MPa were in 10% agreement with test. For irradiated specimens, the estimated YS were 917.41 MPa in 9% agreement.

This study investigated modern architectures adjacent to the road, which can be easily destroyed by economic logic. The purpose of this paper is to find the method to preserve and reuse as townscape. The research methods were used the literature survey and field research of modern architecture in Seoul, and compared with the current status. The result are as followings. Firstly, In order to preserve many architectural cultural properties, the policy related to cultural property should be improved. And, awareness of the individual about cultural property should be changed. Secondly, it has been analyzed that modern architecture can be divided into 3 types in the reuse, which is 'Succession Type', 'Change Type', and 'Extinction Type'. Most of the cases has been used for specific use. Therefore, we should be consider the method of the reuse which can accommodate the various contemporary use. Thirdly, the preservation of the appearance and facade, which is the optimal way to preserve at least the historicity of the city, would be suitable for the preservation of modern architecture adjacent to the road. Lastly, it has been analyzed that the cases can be divided into 2 types in the form of appearance, which is 'Modern Type' and 'Hanok Type'. And, common and individual design guidelines have made.

We analyzed succession of the bacterial communities during composting of animal manure in three individual facilities. Polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE) targeting for the bacterial 16S rRNA gene were used to clarify the changes of bacterial community throughout each composting process. Our study revealed that the bacterial community structures differed during the composting process. The bacterial community in composting of facility A showed little change throughout the process. In the compost sample from facility B, its community had a small shift as the temperature increased. In compost from facility C, the temperature dynamically changed; it was shown that various bacterial communities appeared and disappeared as follows: in the initial phase, the members of phylum Bacteroidetes dominated; in the thermophilic phase, some bacteria belonging to phylum Firmicutes increased; towards the end, the community structure consisted of three phyla, Bacteroidetes, Firmicutes, and Proteobacteria. This study provides some information about the bacterial community actually present in field-scale composting with animal manure.

Vincenzo Scamozzi as the successor of Palladio stands as a major accomplishment of the task of cleanup to the classicism in 16th century. In addition, unlike the trend seen over Palladian, he shows succession and change of Renaissance villa. "L'Idea dell' Archittectura Universale; The Idea of a Universal Architecture"(1615) is a book of Scamozz's representative. This book is represented his idea for a residential building. His concepts for a residential building were analyzed through the analysis of his book and work. Scamozzi thought that domestic architecture should be designed according to he owner's social status and reputation. These concepts as decorum and this is divided into three categories. This is a threefold order, the first category and highest encompassing reigning princess and their families, who were more or less regarded as God's representatives on earth. The second category comprised noblemen and high office holders whose houses were to be, in all respects, a degree less grand, costly and dignified than the prince's residence. The third category was made up of prominent citizens and wealthy merchants whose houses were to have only moderate commoner did not come into this classification at all. - the magnifiche, honorevoli, and commune style of speech.

Korea National College of Agriculture and Fisheries start school at 1997 and 10 for 2,066 people graduate and is becoming the help in youth agriculture and fishery manager education. But recently according to industrial functional staff institutional abolition policy of the government is forecast with the fact that will have a failure to agriculture and fishery manager education. Korea National College of Agriculture and Fisheries was founded for a succession agriculture and fishery manager education. When but while attending military service is under and the education which is continuous is difficult. When after college graduating the reeducation for the agriculture which goes to the military service is necessary. Also Part of the graduate can not participate to agriculture and fishery. This is consistency lack of governmental policy and there is worry which will be criticized. According to FTA agreements the damage is forecast in agriculture and Fisheries. Also prevents the instability of the food supply and which follows in global environment change, respects the stable supply of the foodstuffs which is safe from the agriculture and Fisheries support of the nation is necessary. Consequently proposed the military service substitution institutional plan for the agriculture fishery successor.

The Lago Sofia conglomerates encased in the Cretaceous Cerro Toro Formation, southern Chile, represent a gigantic submarine channel system developed along a foredeep trough. The channel system consists of several tributaries along the trough margin and a trunk channel along the trough axis. Voluminous debris flows were generated ubiquitously along the tract of the submarine channel mainly by the failure of nearby channel banks or slopes. The flows transformed immediately into multiphase flows and resulted in very thick-bedded mass-flow deposits with a peculiar structure sequence. The mass-flow deposits commonly overlie fluted or grooved surfaces and consist of a lower division of clast-supported and imbricated pebble-cobble conglomerate with common basal inverse grading, and an upper division of clast- to matrix-supported and disorganized pebble conglomerate or pebbly mudstone with abundant intraformational clasts. The structure sequence suggests a temporal succession of a turbidity current, a bipartite hyperconcentrapted flow with active clast collisions near the flow base, and a cohesive debris flow probably with a rigid plug. The multiphase flow is interpreted to have resulted from transformation of clast-rich but cohesive debris flows. Cohesive debris flows appear to transform more easily into dilute flow types in subaqueous environments because they are apt to hydroplane. This is in contrast to the flow transitions in subaerial environments where noncohesive debris flows are dominant and difficult to hydroplane.

Ciliate plankton samples were collected biweekly from July 2006 to June 2008 in Jangmok Bay of Geoje Island. Species composition and abundances were analyzed by quantitative protargol stain and environmental parameters were also examined. A total of 88 ciliate species occurred during the study period, consisting of 22 tintinnids, 51 oligotrichs, and 15 other species. Higher ciliate abundances appeared from June to October during the warm season ($<20^{\circ}C$) and the maximum ($4.0{\times}10^4\;cells\;L^1$) in August, while the lower abundances were found during the cold season. The minimun ciliate abundance was found in November when water temperature rapidly decreased. The temporal succession of dominant species was very clear and opportunistic. Pelagostrombidium sp., Tontonia simplicidens, Helicostomella subulata, and Myrionecta rubra were co-dominant in summer while Rimostrombidium orientale occurred abundantly in winter. Strombidium tressum and S. compressum, eurythermal species, were observed during all seasons. Based on the species-specific ecology of ciliate plankton, it is suggested that the indicative ciliate species can be applied as a biological tool to detect environmental change in the southern coastal waters of korea.

Early mosque architecture is time that islam attempts fixing since hjira by Muhammad. Before Umayyad dynasty is established a country since islam occurrence, islamic influence was not extended much and stayed in Mecca area. Of course, when is Patriarchal Caliphate period, although there was part territorial expansion, was in existing islam influence still. Regular territorial expansion to Umayyad dynasty several influences and religious conflict happen. Change about islamic architecture occurred much fatally. Therefore, can find islamic archetype about islamic architecture until Prophet Muhammad period and Patriarchal Caliphate period. Also, Muhammad that is Islamic originator participated to mosque architecture directly in life. Can understand philosophy about islamic architecture that Muhammad seeks in mosque architecture. Was age that seek Muhammad's philosophy department religious succession strongly to Patriarchal Caliphate period. Therefore, can understand role of religion, mosque architecture's meaning and role that seek in Islam. It was just before that early mosque architecture receives effect of conquest area or the surrounding country. Therefore, characteristic of mosque received much effect of Prophet Muhammad and qur'an. Do construction according to qur'an's notice based on Prophet's house's function to early mosque. qur'an is no direct delineation as form or architecture element. qur'an refers thing about spiritual aspect or function about special quality of mosque, role etc..

To investigate the occurrence of modern living planktonic foraminiferal species and their seasonal variations around Jeju Island, we conducted planktonic foraminiferal sampling at KIOST's regular sampling sites during 16 months. In total seven genus and 16 modern planktonic foraminiferal species were identified with six dominant species. Dominant species were Gloigerinoides sacculifer, Globigerinoides ruber, Globigerina bulloides, Noegloboquadrina dutertrei, Pulleniatina obliquiloculata, and Globorotalia inflata. Most of the species were characterized as being typical subtropical species and showed seasonal variations and/or intermittent occurrence from season to season. The occurrence of living foraminifera revealed a strong relationship with water temperature, but not with salinity. Species succession seems to occur along with water temperature changes. Some patch distribution and water temperature dependences appear to be significant since there is a high degree of variation in the occurrence patterns of species and standing stock. More detailed quantitative study is necessary to confirm the species diversity and seasonal variations of planktonic foraminifera and related ocean environmental changes.
