The taxonomic status and scientific names of Artemisia gmelinii and its allied taxa have long been debated. To provide correct names and taxonomic status, A. gmelinii and its allied taxa were reviewed in this study based on morphological characters. After a comparison of original descriptions and type specimens, the names of A. freyniana f. discolor and A. freyniana f. vestita used in Korea were recognized as A. sacrorum var. sacrorum and A. sacrorum var. incana, respectively, based on the characters of the trichome on the leaf, the geographical distributions, the chromosome numbers, and the existence of a pinule connection on the exine of the pollen. A. iwayomogi, the scientific name misused as A. gmelinii, was combined and newly named A. sacrorum var. iwayomogi (Kitam.) M. S. Park & G. Y. Chung based on its morphological similarity to the A. sacrorum group. A description, illustration, and key for each of the taxa are provided here.

The number of tunnels are in fact increasing as a part of linear improvement project of general national highway and road enlargement and pavement project. Recently, collapses of portal slope are also occurring considerably, due to local raining from severe rain storm and abnormal weather. Accordingly, it was risen a necessity to efficiently respond to tunnel portal slope damage and maintenance in Korea and oversea nations. This paper is a basic proposal to execute a survey on the current status and state of the tunnel portal slopes that were already installed and are now being operated along general national highways, and also to execute state evaluation for the purpose of managing those effectively. As a research method, domestic tunnels were analyzed in accordance with geometrical shape such as access type, portal form, and tunnel type, etc. via field survey to analyze the types of tunnel portal slopes along national highways. State evaluation classification sheet is presented to divide classes for the danger state of the surveyed portal slopes, and then the related grades are divided. It is mainly aimed at classifying the tunnel portal slope along national highways with using this state evaluation, to use it as basic data so that continuous maintenance can be executed in the future in accordance with danger classes.

This study is for establishing an appraisal methodology to ensure the accountability of the parliament and to documentation the contemporary historical events related to the National Assembly. It is impossible to documentation comprehensively the activities of the National Assembly through the records schedule of the National Assembly, the current the disposal guidelines of the National Assembly. In particular, this is designed focusing on four affiliated organizations such as the National Assembly Secretariat, so there is a fundamental limit to documentation the outputs of various external agencies and areas where have relationships with the National Assembly. Therefore, it is hard to documentation comprehensively the various issues and historical events occurring in the National Assembly under the current appraisal system. In this situation, this study presents the appraisal methodology, the institutional functional analysis to ensure the accountability of the institution as a first step. However, only with the institutional functional analysis methodology, it is difficult to organize collectively the contemporary historical events or social events ongoing in relation to the fundamental functions of the National Assembly. For this reason, the subject oriented documentation methodology is designed that is the appraisal methodology of selecting the records related to the contemporary social phenomena and historical events according to the functional areas of the National Assembly derived from the institutional functional analysis methodology. Thereby, it is designed that the model of the documentation strategy applicable to the National Assembly in reality.

Mountainous areas are 64% in Korea and are allowed to be used by the permission standards of the "Mountainous Districts Management Act". In the act, slope and elevation criteria are defined to regulate the use of vulnerable land parcels to disaster. However, the standards cannot represent topographical variation in a land parcel such as terrain relief. Therefore, the applicability of slope type standard as a permission standard was tested using Catena in this study. Based on the theoretical grounds, two slope types were analyzed as 'risky slope' with disaster risk. The slope types of landslides in Namwon City were analyzed that 'risky slope' types were distributed about 57%. This study analyzed the forestland parcels that could be used when applying the current permission standards and the parcels that were already used in Namwon City. The ratio of the 'risky slope' in the parcels was more than 50%. Therefore, it is necessary to prevent the mountain development in 'risky slope' by establishing permission standard related to slope types. In addition, this study suggested the ratio of 'risky slope' in the parcel for the permission standard for forestland use conversion.

The purpose of this study is to assist librarians in developing a bibliographic tool for bibliotherapy practices. Bibliotherapy is a form of psychotherapy in which carefully selected leading materials are used to assist a subject in solving personal problems or for other therapeutic purposes. However, bibliotherapy has rarely been either studied or practiced in Korea For a bibliographic tool which is called 'situational leading list', a client situation has to be classified by the factors of biological. place and personal relations. type of stress or symptoms. This study, in this regard, examined related recent researches In the field of psychology or psychoanalysis. Main conclusions made in this study are summarized as follows : The most important factors to classify a client situation in a bibliographic tool are age, sometimes sex, home background, personal relations and mental health issues. This study also suggest the scheme of situation classification according to the decimal classification system. There are the general class, child class, teenager class, adult class and senior class in the classification system.

This study defines the biotechnology industry, examines its position in the domestic economy, and analyses its structure with I-O tables of year 1985, 1990 and 1995. Structural decomposition analysis is used in order to estimate the impact of different sources of growth. We classifies Korean biotechnology industry into 6 sectors, based on the survey of domestic biotechnology industry by Bioindustry Association of Korea. Empirical results indicate that each sector of bioindustry has various sources of growth and industrial demand has led the growth in all sectors except for food-bio and agriculture-bio. For the growth of the industry, each sector needs to cope with the change of the private demand and to improve the import and export structure.

The tribe Neillieae, a small group of about 18 species in the Rosaceae, comprises three taxonomically difficult genera, Neillia, Physocarpus, and Stephanandra. The tribe, characterized by lobed leaves with persistent or deciduous stipules and ovoid, shiny seeds with copious endosperm, is strongly supported as a monophyletic group by a variety of lines of molecular evidence. Due to the high amount of morphological variation across the three genera and the species in tribe Neillieae, conflicting classification schemes and numerous species have been proposed over the past three centuries. However, no comprehensive systematic study of the group, including all species across their geographic ranges, has ever been undertaken. As part of a taxonomic revision of tribe Neillieae, a revision of Physocarpus based on the morphological examination of herbarium specimens, including types, and field observation is presented. Artificial keys, comprehensive nomenclatural treatments, descriptions, distribution maps, and lists of specimens examined are provided. Six species in Physocarpus are recognized. A lectotype is here designated for the following species: Opulaster pubescens, Opulaster ramaleyi, Spiraea opulifolia var. parvifolia, Spiraea opulifolia var. tomentella, Physocarpus michiganensis, and Physocarpus missouriensis.

Market Segmentation for Freight Transportation has been used to know the strategies both efficiency of freight transportation market and attraction of freight volume for carriers. It was so difficult to understand the individual preference of shippers that all shippers could be only homogenized through market segmentation. In Korea. standard Industrial classification has been used for freight market segmentation. This study evaluated another new market segmentation method for manufacturing industry. From the study, we knew that the best relevant market segmentation criterion was annual input-output volume, which showed excellent segmenting ability. Also. the results showed many differences against segmentation results according to standard industrial classification. This study had a meaning as a new trial which segmented freight transportation market using company size and shipment characteristic data.

기존 저수지 농업용수는 주로 논의 벼재배 용수공급을 목적으로 설계되었지만, 논 지역 타작물 재배 지원 등의 정책으로 논에서 밭으로 전작화가 증가함에 따라 농업용수의 효율적 분배를 위한 논의 전작화 패턴 분석이 필요한 실정이다. 이에 본 연구에서는 공공데이터 포털의 2019년 팜맵을 활용하여 최신 경지 현황을 파악하고, 환경부의 2007년, 2019년 토지피복지도를 이용하여 전작화 패턴을 분석하였다. 구축된 팜맵과 토지피복지도는 환경부 토지피복분류 기준 농업지역 중분류로 일치시켜 분석에 활용되었다. 논, 밭, 시설재배지 등의 농경지 이용 현황 및 전작화 추이는 전국 단위, 권역 단위로 분석되었고, 주요 시도와의 공간적 거리를 전작화 영향인자로 설정하여 DUP(Degree of Urban Proximity) 등의 지표로 그 영향을 확인하였다. 또한, 전체 경지 중 논, 밭의 면적과 증감 추이를 ACR(Area Change Rate) 등의 지표로 전작화 규모를 파악하였고, LPI(Largest Patch Index), LSI(Landscape Shape Index) 등의 지표로 개별/집단화 전작의 패턴분석을 수행하였다. 본 연구로 제시된 저수지 수혜 구역별 논의 전작화 패턴은 논 벼재배와 농업용수 수요 특성이 상이한 밭작물에 안정적 용수공급 체계 구축 등의 기초자료로 활용 가능할 것으로 생각된다.
