Topsoil including numerous soil seedbanks has been known to be a valuable material for ecological restoration. There is a lack of specific study for its utilization in the field of stream restoration. This study conducted a revaluation of the value of topsoil as a material for stream restoration. Furthermore, an ecological technique using topsoil was applied in an improvement project of a stream environment at the Hwanggujicheon Stream in Korea. Stockpiling and spreading topsoil was specifically applied to the revegetation of a low slope revetment and a high flow plain. The result of this application showed that topsoil played an integral role in eco-friendly restoration in terms of ecological, flood control, economic, and constructional aspects. In conclusion, this study's findings suggest that topsoil is a suitable candidate material for stream restoration.

This study aims to investigate the changing aspects about research methodology of stone pagoda from the period of Japanese colonial to now. There were the differences in purpose, method and analysis of the research according to each period. In Japanese colonial period, the purpose of research was to make lists of almost stone pagodas in Korea. Following this, Japanese researchers conducted detailed research for academic purpose. They took measurements of stone pagodas and made drawings. After liberation the research was focused on the relics contained in pagodas. They proceeded to investigate the inner relics in order to attract the attention of the people. In the late 1900's, the repair works of cultural heritages were increased. Many reports of the repair works were released and sent to administration offices. The reports contained the change aspects of situation between before work and after with drawings or simple investigation documents. In the 1990's, the restoration works for important stone pagodas were started by the National Research Institute of Cultural Heritage. Since then, researches from various way - architectural and conservational researches about historical interpretation, shape, structure, proportion, technique, etc. - progressed for careful restoration and accurate study. In Recent years, various professional organizations(in the field of structure, physics, chemistry, biology, lithology, etc.) started to join the researches. Researches conducted studies directly with the stone pagodas, as well as conducting indirect studies with the stone pagodas, such as the structural stability of stone pagodas, the characteristics of rock, and conservation chemicals. Today the research project 'The preservation project of stone cultural property' is being conducted by the National Research Institute of Cultural Heritage. The purpose of this project is to gain more detailed and accurate investigation documents to be provided for the people. In conclusion, researches from various fields must be included in the research. Furthermore, a synthetic study should be done through comparing similar characteristics or different characteristics among many research results.

The need for changes in archival studies curriculum has been steadily raised because of the wide variation of the curriculum in each graduate school. In this study, the foreign archival studies guidelines and certification standards were compared and analyzed to derive key categories and elements for developing the Korean guidelines for a graduate program in archival studies. The five key categories and elements of the guideline include introduction, mission and goal, knowledge categories, administrative factors, and conclusion. On the other hand, the 10 knowledge categories to be learned by archivists include ① The Nature of Records and Archives, ② Selection, Appraisal, and Acquisition, ③ Arrangement and Description, ④ Preservation, ⑤ Reference and Access, ⑥ Outreach, Instruction, and Advocacy, ⑦ Management and Administration, ⑧ Social and Cultural Systems, ⑨ Legal and Financial Systems, and ⑩ Information Technology. In the future, knowledge categories need to be actively reflected by the opinions of the academic community and archivists to improve the graduate curriculum.

Korea began preserving and managing natural monuments in 1933 under the Japanese Colonization, but South and North Korea had to establish natural monument management policies separately because of the division after the Korean Independence. The purpose of this study is to compare and analyze the natural monument designations of South and North Koreas between 1933 and 2005 to introduce advanced polices for Oneness-Korea. The following are the results: According to data of December 2005, South Korea has 358 and North Korea has 474 natural monuments. North Korea has 116 more natural monuments than South Korea. In addition, over half of South Korea's designations are plants, whereas North Korea's designations are relatively well-balanced. Both South and North Korea designate plants(mostly trees) that are old and large. However, South Korea emphasizes the historical value of village forests, contrary to economic value in North Korea. Also, North Korea preserves many traditional fruit trees which have not been well-preserved in South Korea. As for animals, South Korea designates migratory wild animals by type and not by region to protect them at a national level, whereas North Korea designates the specific habitats of each type of wild animal. In addition, North Korea protects each region's cattle and chickens to preserve native traits of domesticated animals. Geologically, North Korea preserves 18 hot springs and 11 springs, whereas South Korea has none. Geographically, North Korea preserves 81 waterfalls, lakes, etc. In the conclusion, advanced natural monument management of South and North Korea is necessary to achieve effective preservation of natural monuments.

Although the National Archives of Korea has been receiving transfer of standard electronic documents with a retention period of more than 30 years from the central administration since 2015, errors and inefficiencies persist. Despite this, however, there remain no studies that analyze or address these issues. This study aims to bridge this gap and found that most errors in the transfer process occur at the production stage. To address such, this study proposes a four-step solution. First, before electronic document approval, the text and attached files are checked for defects to prevent errors. Second, as soon as the signature is made, digital signatures are applied on a file-by-file basis to ensure integrity. Third, integrity verification and transfer inspection are automatically performed through digital signature investigation and defect check procedure during transfer and preservation. Fourth and last, the criteria of acquiring records and integrity guarantee technologies are properly applied in production stage with proper management and supervision.

G protein-coupled receptor kinase 5 (GRK5) has been considered as a potential target for the treatment of heart failure as it has been reported to be an important regulator of pathological cardiac hypertrophy. To discover novel scaffolds that selectively inhibit GRK5, we have identified a novel small molecule inhibitor of GRK5, KR-39038 [7-((3-((4-((3-aminopropyl)amino)butyl)amino)propyl)amino)-2-(2-chlorophenyl)-6-fluoroquinazolin-4(3H)-one]. KR-39038 exhibited potent inhibitory activity (IC₅₀ value=0.02 µM) against GRK5 and significantly inhibited angiotensin II-induced cellular hypertrophy and HDAC5 phosphorylation in neonatal cardiomyocytes. In the pressure overload-induced cardiac hypertrophy mouse model, the daily oral administration of KR-39038 (30 mg/kg) for 14 days showed a 43% reduction in the left ventricular weight. Besides, KR-39038 treatment (10 and 30 mg/kg/day, p.o.) showed significant preservation of cardiac function and attenuation of myocardial remodeling in a rat model of chronic heart failure following coronary artery ligation. These results suggest that potent GRK5 inhibitor could effectively attenuate both cardiac hypertrophy and dysfunction in experimental heart failure, and KR-39038 may be useful as an effective GRK5 inhibitor for pharmaceutical applications.

Archival organizations have been evolving to varying users' needs. The main functional focus of earlier archival organizations has inclined to collection and preservation of data, but their current interests expand to utilization of the data collected. Therefore, today's archival organizations endeavor to procure user-oriented archival information service. This study highlights the programs initiated in last two years by 'Service Innovation Team', a special task force of National Archives of Korea organized in 2005, and presents comparative analysis of those programs with respect to the existing archival systems of National Archives and Records Administration of USA and The National Archives in UK. Additionally, the study, while emphasizing the importance of enlarging and diversifying service programs as well as promoting public awareness over archive resources, introduces the service standards of advanced nations as benchmarks for future archival service policies of pertinent organizations.

Objectives: The objective of this study was to observe the anti-amnesic effects of Yukmijihwang-tang (YMJHT), on the scopolamine (Sco)-induced memory impairment in C57BL/6 mice through its favorable acetylcholine (ACh). Also, to observe acetylcholinesterase (AChE) activity, Choline acetyltransferase (ChAT) mRNA expressions, and antioxidant effect. Methods: Six groups, with a total of 20 normal and 100 Sco treated mice were selected based on their body weights after 1 week of acclimatization, were used in this study as follows. Half of the mice in each group were used for passive avoidance task tests and hippocampus ACh content, AChE activity and ChAT mRNA expression measurement, and the remaining half in each group used for Morris water maze test and measurement of cerebral antioxidant defense system. Results: Amnesia due to AChE activations and destroyed cerebral cortex antioxidant defense systems were markedly and dose-dependently inhibited after 28 days of continuous oral pre-treatment with YMJHT 400, 200 and 100 mg/kg, respectively. The overall effects of YMJHT 400 mg/kg were similar to those of tacrine 10 mg/kg. Conclusions: Based on the results, it was established that oral administration of YMJHT favorably alleviates Sco-induced memory impairment, through preservation of ACh, mediated by up-regulation of ChAT mRNA expressions and related AChE inhibition and augmentation of cerebral antioxidant defense system, at least in a condition of this experiment. The overall effects of YMJHT 400 mg/kg were similar to those of tacrine 10 mg/kg.

This study examines visitors' image and behavior characteristics of Wolseong palace in Gyeongju. This area has been a royal palace during Silla periods. So many scholars dedicate to the protection of this historical-cultural heritage. The research process consists of two main steps, such as on-site field investigation and survey research. The data were collected in summer and autumn. Collected data is classified into three groups to describe visitors' behavior, time, space, and then processed by statistical methods. The results are as follows: First, there is a shortage of programs and facilities. The result shows most visitors consider Wolseong palace as a pathway for walking. Hence better functions should be developed to attract more visitors but with least effect to historical remains. The founding is that increasing programs for history exploration, enhancing lighting installation, facilities, plant arrangement, road condition and so forth would be suggested.
