The Study is to investigate information resources recognition of collection development policy that is a key element of Gwangju representative library. 68 Librarians, 98 library users and 20 libraries responded the questions of information resources. The fields of the questions are media, subjects and levels of information resources. The results of the research are as follows. First, the correlation coefficients between librarian group's preference and need is lower than that of the user group. Second, information resources for the knowledge-disadvantaged has low preference and need but the actual usage rate was high. Third, Librarians need to transfer historical paper and books, historical objects, technical reports and journal articles to the representative library. Fourth, information resources about philosophy have middle preference, low need and the resources have low need for transfer to representative library. Fifth, local historical resources and administrative policy resources has low usage rate high need for transfer to representative library. Sixth, the level of public library in Gwangju is 1.837 and the expectative level of Gwangju representative library is 3.325.

In this study, using the RCP scenario for Hyoja Drainage subbasin of Cheonggyecheon, we analyzed the change with the Historical and Future rainfall calculated from five GCMs models. As a result of analyzing the average rainfall by each GCMs model, the future rainfall increased by 35.30 to 208.65 mm from the historical rainfall. Future rainfall increased 1.73~16.84% than historical rainfall. In addition, the applicability of LID element technologies such as porous pavement, infiltration trench and green roof was analyzed using the SWMM model. And the applied weight and runoff for each LID element technology are analyzed. As a result of the analysis, although there was a difference for each GCMs model, the runoff increased by 2.58 to 28.78%. However, when single porous pavement and Infiltration trench were applied, Future rainfall decreased by 3.48% and 2.74%, 8.04% and 7.16% in INM-CM4 and MRI-CGCM3 models, respectively. Also, when the two types of LID element technologies were combined, the rainfall decreased by 2.74% and 2.89%, 7.16% and 7.31%, respectively. This is less than or similar to the historical rainfall runoff. As a result of applying the LID elemental technology, it was found that applying a green roof area of about 1/3 of the urban area is the most effective to secure the lag time of runoff. Moreover, when applying the LID method to the old downtown area, it is desirable to consider the priority order in the order of economic cost, maintenance, and cityscape.

This study focuses on the analyzing historical and cultural resources formed during the Goryeo, Chosun, and Anti-Japanese Movement periods after the Silla period with the aim of finding ways to utilize its cultural contents. The viewpoint of analysis was made from the perspective of exchange, naturalization, and faith, and the following conclusions were obtained from the analysis. First of all, from the exchange perspective, the activities of Choi Chi-won, Seogyu, and Song Young-gu contributed to the formation of regional historical and cultural contents, such as leaving a lot of ruins or geographic stories in the area and a heritage of good human exchange. From the point of view of naturalization, Du Kyung-ryeong, Cheon Man-ri, and Jeong Yul-seong contributed to the history and culture of the story and the formation of heritage by doing such as contributing activities to the war, anti-Japanese movement for the nation, and the formation of the nation. The most representative from a religious point of view is the Guan Yu faith, which has become a faith believed by the authorities and civilian as a brave longevity and a symbol of the victory of war. The related symbols, paintings, etc. also are objects of worship and have become valuable local Chinese cultural resources as artistic values. Therefore, from a cultural point of view, there is a need to further develop and utilize these China-related historical and cultural resources as good cultural contents by elaborating their stories and local festivals, book culture branding, international music festivals, and exploring various cultures such as Chinese tour courses.

The thesis of this analytical study includes 1) the generation of annual and monthly discharge regarding single hydrological variable at single site, 2)comparsion with the historical records and the generation, and 3) changing the monthly generatied discharge into annual. The conclusion of this will be used for the future plan for water resources development. Annual discharges at waegwan are characterized by log-normal distirbution and persistence-absent. Also, the random number generator causes the errors in the generation of annual discharge. The serial correlation coefficients of the generated annual discharge have less value than that of historical records, while the correlation coefficient and slope in January have(+) value and opposite to historical record. To change the monthly generated discharge into annual is not proper.

The idea that city culture can be employed as a driver for urban development has become part of the new orthodoxy by which cities seek to enhance their competitive position. Such development reflect not only the rise to prominence of the cultural sphere in the city development, but also how the meaning of culture has been refined to include new uses in order to meet the main objectives of sustainable development. This study focuses on the procedure how the cultural infrastructure and historical context can be applied for urban regeneration strategy. Two successful cases (Bilbao, Spain and Yokohama, Japan) were selected for analysis of strategies as a whole, background, main characteristics of culture-led urban regeneration strategies and their effect for urban regeneration have been analyzed in detail. In conclusion, lessons for the future development were suggested in terms of resources, planning and linking strategies.

The magnitude of natural disaster is much bigger than the past. Only short time return period can be estimated due to limited number of measured data. Therefore, back-data extension studies are undergoing in various area through historical records. In this study, data gathering and analysis of historical flood records such as Joseon wangjo sillok(Annals of Joseon Dynasty) and Jeungbo munheon bigo (enlarged encyclopedic literature) was achieved for the usage of extreme flood study in various ways. Analysis of 479 flood events from Joseon wangjo sillok and 143 flood events from Jeungbo munheon bigo during Joseon Dynasty was conducted in statistical way.

In this study, the chukwookee data were evaluated by applying that for the historical rainfall frequency analysis. To derive a two parameter log-normal distribution by using historical data and modern data, censored data MLE and binomial censored data MLE were applied. As a result, we found that both average and standard deviation were all estimated smaller with chukwookee data then those with only modern data. This indicates that rather big events rarely happens during the period of chukwookee data then during the modern period. The frequency analysis results using the parameters estimated were also similar to those expected. The point to be noticed is that the rainfall quantiles estimated by both methods were similar, especially for the 99% threshold. This result indicates that the historical document records like the annals of Chosun dynasty could be valuable and effective for the frequency analysis. This also means the extension of data available for frequency analysis.

This presentation highlights the IAHR book, recently published last April, of which the author is the editor-in-chief, on the historical water projects and traditional water technologies of international interest in the Asian region, addressing information on past water projects (mostly before the 20th century) in the regions that are technically and culturally of interest and educationally valuable. The book explores historical water projects in these regions, presenting technologies used at the time, including calculation and forecasting methods, measurement, material, labor, methodologies, and even water culture. Through this book, it is expected that the old Asian wisdom of "reviewing the old and learning the new" would be realized to a certain extent in modern planning and practice of water projects. The book comprises a lead article that the presenter authored and five Parts representing China, Japan, Korea, South Asia, and Southeast Asia, respectively, followed by an invited one from Uzbekistan. Throughout the book, it is found that historically the Asian monsoon, affecting the Indian subcontinent and Southeast and East Asian regions, induced rice cultivation. It fundamentally needs proper irrigation systems, including reservoirs (dams) and canals, water wheels, and even rain gauges. Flood risks have been more common in Asia than Europe under this climate condition, as recognized in history. To utilize and sometimes overcome these climate conditions, people built and managed many historical and grandiose water projects and invented and used localized but sophisticated water-related technologies in the Asian region.
