As the recognition of the importance of user-oriented services is increasing, there has been a heightened attention for finding aids that could improve the effectiveness of searching. This study tried to draw various facet elements that can be applied to the presidential records retrieval system using presidential records as cases in analyzing various resources, considering the importance of facets in finding aids for the improvement of effectiveness in searching in the future and the importance of presidential records in Korea. In drawing facet elements based on the characteristics of presidential records, the websites of the National Archives (NARA) and Presidential (Prime Ministers') Archives as well as their search options were examined as cases. In addition, the morpheme of each title of presidential records were analyzed, as well as the terms entered by the users of the Presidential Archives Portal of Korea, the terms used in the request for information disclosure toward the Presidential Archives in Korea, the search options of the Presidential Archives Portal, and the elements of the description and metadata standards. The significance of this study lies on suggesting the methodology of developing various facets as main elements in finding aids using the presidential records as cases.

Recently, new ginseng cultivars having superior agricultural traits have been developed in Korea. For newly developed plant cultivars, the identification of distinctiveness is very important factors not only in plant cultivar management but also in breeding programs. Thus, eighty-five inter simple sequence repeat (ISSR) primers were applied to detect polymorphisms among six major Korean ginseng cultivars and two foreign ginsengs. A total of 197 polymorphic bands with an average 5.8 polymorphic bands and 2.9 banding patterns per assay unit across six Korean ginseng cultivars and foreign ginsengs from 236 amplified ISSR loci with an average 6.9 loci per assay unit were generated by 34 out of 85 ISSR primers. Three species of Panax ginseng including the Korean ginseng cultivars, P. quinquefolius, and P. notoginseng, could be readily discriminated using most tested primers. UBC-821, UBC-868, and UBC-878 generated polymorphic bands among the six Korean ginseng cultivars, and could distinguish them from foreign ginsengs. Sequence characterized amplified region (SCAR) marker system was introduced in order to increase the reproducibility of the polymorphism. One SCAR marker, PgI821C650, was successfully converted from the randomly amplified polymorphism by UBC-821. It showed the expected dominant polymorphism among ginseng samples. In addition, the specific polymorphism for Sunwon was generated by treating Taq I restriction enzyme to polymerase chain reaction products of PgI821C650. These results will serve as useful DNA markers for identification of Korean ginseng, especially Sunwon cultivar, seed management, and molecular breeding program supplemented with marker-assisted selection.

The concept of strategic group is defined as an aggregate of corporations utilizing similar strategies with similar resources. It becomes a kinds of contact point in the middle of corporation and industry between the industrial organization theory and the strategic management theory. This study tried to apply the strategic group model, which has been a main theory in the management studies, to program providing industry in Korea. This study shed lights upon research problems such as number of strategic groups, differences of strategic variables among the groups, finally differential performances according to strategic groups. 40 commercial broadcasting companies were analyzed to find answers. 9 strategic groups were drawn as a result of cluster analysis. Major variables which contribute to making groups were operating efficiency(4.05), pricing(3.83), size(number of system operator, 3.56), reliance on license revenue(2.58), horizontal integration(number of sister networks, 2.16) in order. An analysis of variance between performance variables has shown statistical significance regarding total net revenue per subscriber, however, insignificances statistically in regards to ratio of operating profit to net sales, cash Abstracts 687 flow ratio. Some studies in the past insisted that history variable played an important role to classifying strategic groups. However, this study found that the history didn't exert significant influence on either the group classification itself or performance.

Objectives: The exponential growth of chemicals, an area of high concern in developed countries like the US (i.e., the Gore Initiative) and in the EU (i.e., REACH), as well as recent chemical accidents in Korea, have provoked nationwide concerns and resultant legal enforcement. This study aims to compare the laws of the Ministry of Environment (the Chemical Substances Control Act (CSCA), Act on the Registration and Evaluation, etc. of Chemical Substances (ARECS)) with those of the Ministry of the Employment and Labor (Occupational Safety and Health Act (OSHA)). Methods: Each law pertaining to the Ministry of Environment and the Ministry of the Employment and Labor was downloaded from the official legal information system (www.law.go.kr). The objectives of each law and the major contents related to chemical management were compared and summarized. Results: The CSCA and the ARECS are focused on the protection of people and the environment, while the OSHA relates to the protection of workers. The right to know of people and workers has been reinforced. The former two laws emphasize prevention, but the OSHA contains both preventive and post-accident measures. The role of the Ministry of Employment was reinforced with the promulgation of the CSCA and ARECS, which contain regulations such as adjacent area impact evaluation, risk control planning, chemical statistical survey and construction and operation of information, provision of risk control plans, response to chemical accidents and registration of chemical substances. Conclusion: We found that the three laws discussed here have several similar clauses designed to protect people and the environment from risks that may be caused by the use of chemicals, even though there are some differences among them in terms of objectives and contents. This review concluded that several clauses that can be regarded as double regulation should be unified in order to minimize the waste of government administrative resources and socio-economic losses.

The purpose of this study is to establish academic identity as well as produce human resources that industries need by grasping curriculum of the departments related beauty focusing on Korean colleges (junior colleges and four year course colleges), analyzing examples of advanced countries and suggesting their developmental direction. For the research method, the reference period of curriculum in Korean colleges was from Jul. 05th, 2011 to Aug. 05th, 2011. the investigation method is as follow: first, the curriculum of the departments related to beauty which were registered in the web sites were investigated. Second, the documents were received by fax and Email from each department after calling it. Third, questions and answers were done in reference to majors on the phones. these methods are intended for 65 junior colleges and 16 four year course colleges (total 81 ones). It clarified that lifelong education centers and the graduate courses were ruled out. the statistical analysis about data which were investigated like this were done by the frequency analysis. The results which examined the major subjects of Make-up focusing on Korea and foreign countries are as follow: First, the result which examined the major and theory subjects of Make-up has found that there are the human body theory, the equipment theory, the marketing theory are the management theory in Korean junior colleges and physiology/chemical, management, marketing and equipment product were treated in four year course colleges of Korea. As for foreign colleges, the subjects related to history and culture are mainly treated as the theory courses and their purpose is to cultivate basic knowledge of the fields which are mainly connected to Make-up including plays, movies, TV and studios. Second, the result which examined practice subjects of Make-up major has found that practice subjects of the total ones are of great importance in junior colleges. And it could be found that the Make-up field is of little importance as it is not independent and exists with the hair and skin fields in one department in the four year course colleges. Especially, in the foreign countries, the more detailed and professional subjects including classes which treat digital media, studio technologies, production, wigs and the special effects were treated by the field class system and these characteristics implies that Korean curriculum should be changed in the future. Based on this analytical results of investigation, this researcher tried to propose the developmental direction of Korean curriculum in the future.

Due to habitat damage associated with climate change and human activities, biodiversity has decreased all over the world. In order to prevent further reduction in biodiversity, the international community has endeavored to establish a cooperative system, such as the Convention on Biological Diversity (CBD). Until now, most biodiversity strategic planning has been led by the national government. However, the National Biodiversity Strategy and Action Plan is conservative and its strategic plan is vague. Therefore, we propose a method for managing local biological resources called the Local Biodiversity Strategy and Action Plan. In order to provide the strategic plans and detailed plans for the Local Biodiversity Strategy and Action Plan, the report has examined several cases including Convention on Biological Diversity, Strategic Plan for Biodiversity 2011-2020, and the biodiversity strategies and action plans of the Republic of Korea and several other countries. As a result, the report demonstrates the survey and protection of bio-species, the designation and monitoring of conservation region, the management of the integrated eco-network, the establishment of biodiversity organizations and capacity building, the methods to promote networking and traditional knowledge, and the strategy for development in bioindustry. Consequently, the implementation of biodiversity management strategies by local governments will play a significant role in preserving and increasing biodiversity by realizing the goals of Strategic Plan for Biodiversity 2011-2020.

Resilience has been widely used in various fields including design and operation of infrastructures. The resilient infrastructures not only reduce the damage scale of various disasters but also reduce the time and cost required for restoration. However, resilience rarely applied to promote efficient management of agricultural infrastructures. Recently, drought is an aggravating disaster by climate change and need countermeasures. Therefore, we tried to demonstrate evaluating measures in case of drought under consideration of resilience. This study applied the robustness-cost index (RCI) to evaluate alternative solution of the supply problem of a large agricultural reservoir under drought conditions. Four structural alternatives were selected to estimate the robustness index (RI) and the cost index (CI) to obtain the RCI values. Structural alternatives are classified into temporary measures and permanent measures. Temporary measures include the development of a tube wells and the installation of the portable pump, while the permanent measures include the installation of a pumping stations and the pumping water to the reservoir (Yeongsan River-Naju reservoir). RCI values were higher in permanent measures than those of temporary measures. Initial storage of the reservoir also affected RCI values of the drought measures. Permanent measures installation and management of early stage of the reservoir storage shortage was identified as the most resilient system.

The objective of this study was to evaluate future inundation risk of farmland according to the application of coupled model intercomparison project phase 5 (CMIP5) and coupled model intercomparison project phase 6 (CMIP6). In this study, future weather data based on CMIP5 and CMIP6 general circulation model (GCM) were collected, and inundation was simulated using the river modeling system for small agricultural watershed (RMS) and GATE2018 in the Tanjung district of the Moohan stream watershed. Although the average probable rainfall of CMIP5 and CMIP6 did not show significant differences as a result of calculating the probability rainfall, the difference between the minimum and maximum values was significantly larger in CMIP6. The results of the flood discharge calculation and the inundation risk assessment showed similar to trends to those of probability rainfall calculations. The risk of inundation in the future period was found to increase in all sub-watersheds, and the risk of inundation has been analyzed to increase significantly, especially if CMIP6 data are used. Therefore, it is necessary to consider climate change effects by utilizing CMIP6-based future weather data when designing and reinforcing water structures in agricultural areas in the future. The results of this study are expected to be used as basic data for utilizing CMIP6-based future weather data.

According to the standard guidelines of design flood (MLTM, 2012; MOE, 2019), the design flood is calculated based on past precipitation. However, due to climate change, the frequency of extreme rainfall events is increasing. Therefore, it is necessary to analyze future floods' volume by using climate change scenarios. Meanwhile, the standard guideline was revised by MOE (Ministry of Environment) recently. MOE proposed modified Huff distribution and new CN (Curve Number) value of forest and paddy. The objective of this study was to analyze the change of flood volume by applying the modified Huff and newly proposed CN to the probabilistic precipitation based on SSP and RCP scenarios. The probabilistic rainfall under climate change was calculated through RCP 4.5/8.5 scenarios and SSP 245/585 scenarios. HEC-HMS (Hydrologic Engineering Center - Hydrologic Modeling System) was simulated for evaluating the flood volume. When RCP 4.5/8.5 scenario was changed to SSP 245/585 scenario, the average flood volume increased by 627 ㎥/s (15%) and 523 ㎥/s (13%), respectively. By the modified Huff distribution, the flood volume increased by 139 ㎥/s (3.76%) on a 200-yr frequency and 171 ㎥/s (4.05%) on a 500-yr frequency. The newly proposed CN made the future flood value increase by 9.5 ㎥/s (0.30%) on a 200-yr frequency and 8.5 ㎥/s (0.25%) on a 500-yr frequency. The selection of climate change scenario was the biggest factor that made the flood volume to transform. Also, the impact of change in Huff was larger than that of CN about 13-16 times.

This study was carried out to elucidate the development of unprecedented water-bloom caused by a single species of colonial green algae Eudorina elegans in the upstream area of the Seungchon weir located in the Yeongsan River from late April to May 2013. The Yeongsan River is typically regulated system and the waterbody is seriously enriched by both external and internal sources of nutrients. Seasonal algal outbreaks were highly probable due to various potential factors, such as the excessive nutrients contained in treated wastewater, slow current, high irradiation and temperature, in diatom (winter), green algae (spring) and bluegreen algae (summer). Spring green-tide was attributed to E. elegans with level up to $1,000mg\;m^{-3}$(>$50{\times}10^4cells\;mL^{-1}$). The bloom was exploded in the initial period of the algal development and after then gradually diminished with transporting to the downstream by the intermittent rainfall, resulting in rapid expansion of the distribution range. Although the pulsed-flows by the weir manipulation was applied to control algal bloom, they were not the countermeasures to solve the underlying problem, but rather there still was a remaining problem related to the impact of pulsed-flows on the downstream. The green-tide of E. elegans in this particular region of the Yeongsan River revealed the blooming characteristics of a colonial motile microalga, and fate of vanishing away by the succeeding episodic events of mesoscale rainfall. We believe that the results of the present study contribute to limno-ecological understanding of the green-tide caused by blue-green algae in the four major rivers, Korea.
