  • The genus Actinidia has been recorded as having total six taxa, composed of four species and two varieties, in Korea. However, its taxonomy remains complex because of disagreement on taxonomic characters used for species boundaries. Based upon morphological, anatomical, and palynological characters, we re-evaluated species delimitations in the genus Actinidia. Critical observation of wild populations and extensive herbarium materials including types were also carried out. It is generally considered that leaf thickness and shape, hair type and color were important diagnostic characters to identify species, but these characters were insufficient to be diagnostic characters because of their wide variation ranges. On the other hands, pith pattern, winter bud protrusion rate, scale leaf number, anther color, fruit shape, and maturity season were taxonomic significance. A. arguta var. platyphylla and A. arguta var. rufinervis have been identified by hair type and color, but these characters showed continuous variation in A. arguta. Therefore, two varieties are treated as synonyms of A. arguta. Consequently four species are recognized in Korea: A. polygama, A. kolomikta, A. rufa, and A. arguta. A key is provided, as well as complete descriptions of the species examined, including information on nomenclatural types, and synonymies.

  • The morphological characters and scientific names on 3 taxa of Korean Euphorbia were reviewed. Growing pattern of stems, arrangement of leaves, the presence of appendages, the presence of ovary's hairs, shape of seeds and the presence of caruncles were valuable characters in identifying the taxa. The correct scientifie names of Nang-dok, Keun-ttang-bin-dae and Ae-gi-ttang-bin-dae were E. fischeriana, E. hypericifolia and E. maculata respectively based on the morphological characters, the type specimens and the original descriptions. Keys to the species were provided for the accurate identification.

  • In constructing a credit scorecard, each characteristic variable is divided into a few attributes; subsequently, weights are assigned to those attributes in a process called coarse classification. While partitioning a characteristic variable into attributes, one should determine appropriate cutpoints for the partition. In this paper, we propose a cutpoint selection method via penalization. In addition, we compare the performances of the proposed method with classification spline machine (Koo et al., 2009) on both simulated and real credit data.

  • 본 연구는 최근의 제도개선으로 그 중요성이 증대되고 있는 상대가치계산 방식의 대안으로서 주가수익가치평가방식(Price-Earnings Valuation:이하 'P/E방식'이라 한다)을 우리 나라 시장에 적용하고 그 정확성을 검증한다. P/E방식에 따른 기업의 주가는 당해 기업의 주당수익과 유사기업으로부터 산출된 적정 주가수익비율(P/E 배수)을 곱함으로서 결정된다. 1988년에 우리 나라 시장에 상장된 기업을 대상으로 P/E방식을 사용한 연구결과는 두가지측면에서 중요한 시사점을 제공하고 있다. 첫째, 유사기업 선정시 현행 표준산업분류표보다는 주당수익 혹은 주당경상이익을 선정기준으로 사용했을 때 예측오차가 훨씬 줄어들고 있음을 보여주고 있다. 둘째, 비교기준가격산정시점이 상장시점에 근접할수록 예측오차는 더 적음을 보여주고 있다. 특히 P/E방식을 사용할 때 유사기업선정기준에 대한 본 연구의 결과는 금융선진국을 중심으로 한 선행연구결과와 일치하지 않고 있으며[Alford(1992), Kahle and Walkling(1996)], 우리 나라 공모주의 가격산정 및 기존 상장주식의 향후 비교가치 평가시에 반드시 고려될 필요가 있다고 본다.

  • The relocation project of the US military base in South Korea is a large-scale national project aimed at ensuring a stable presence of US troops stationed in South Korea and strengthening the future-oriented Korea-US Alliance by relocating the US military base scattered across the country to Pyeongtaek. The purpose of this study is to examine the classification of records produced by various agencies involved in the relocation project, including the MND USFK Base Relocation Office that is the main body of the project, and provide basic data for systematic records management in the future. This study aims to ensure the people's right to know and achieve the objective of the transmission of the military documentary heritage at a macro level.

  • In this paper, classification feature is selected with focus of musical content, note sequences pattern, and measures similarity between note sequences followed by constructing clusters by similar note sequences, which is easier for users to search by showing the similar note sequences with the search result in the CBMR system. Experimental document was $\ulcorner$A Dictionary of Musical Themes$\lrcorner$, the index of theme bar focused on classical music and obtained kern-type file. Humdrum Toolkit version 1.0 was used as note sequences treat tool. The hierarchical clustering method is by stages focused on four-type similarity matrices by whether the note sequences segmentation or not and where the starting point is. For the measurement of the result, WACS standard is used in the case of being manual classification and in the case of the note sequences starling from any point in the note sequences, there is used common feature pattern distribution in the cluster obtained from the clustering result. According to the result, clustering with segmented feature unconnected with the starting point Is higher with distinct difference compared with clustering with non-segmented feature.

  • This paper is concerned with the problem of international approval of national parks in Korea. Much of the solution of this problem is to be found in planning and law. Therefore the provisions for planning in the Korean. Natural Park Law and 20 national park plans were analyzed in comparison with International criterion. Then an gradual changing model of zoning plan were proposed in order to improve the zoning plan of national parks in Korea and applied to Hallasan National Park. These model can be applied to change the zoning plans of national parks in Korea for international approval.

  • Records at closed private universities are simply kept in stacks without the use of records classification systems. However, the systematic management of such records is needed as these are important records that have legal and evidential value during the litigation process. Therefore, this study intends to develop a classification system for recordkeeping at closed private universities aiming to eliminate unnecessary follow-up procedures that may occur because of the absence of a records classification system, and to develop practical tools for managing records at closed universities. To this end, Seonam University, among the 13 transfer records kept by the Korea Advancing Schools Foundation, was selected as the example for this study. The peculiarities of the closing processes and the catalogs of the transfer records were reviewed, and a business function analysis was conducted. Based on the Guidelines for Prescribing Retention Period of University Records by the National Archives and the Ministry of Education, a records classification system for the closed private universities was proposed for the Records Disposition Schedule to handle the uniqueness of closed universities.

  • This paper surveyed the research trends in archival appraisal science in Korea. All 33 articles from 4 relevant academic journals articles were analysed on the basis of quantitative measurement and thematic sorting. The number of the articles by the record managers or archivists working at the public bodies has especially decreased for some time past. A distinguishing feature was a decline in interest in the present appraisal system and methodology. Correspondence between practice and academic theory be required for the future development in archival appraisal.
