동해안 석호는 해수와 담수가 섞인 독특한 형태의 기수호이며, 수변식생이 발달되어 생물다양성이 풍부한 지역이다. 본 연구는 국내에 분포하는 17개소의 석호에 대한 식물상과 식물 종조성 등의 조사를 통하여 석호 식생에 대한 안정적인 보전계획 수립을 위한 기초자료를 제시하고자 한다. 17개소의 석호에 대한 식물상 조사결과, 관속식물은 118과 378속 655종 13아종 46변종 6교잡종, 총 720분류군이 확인되었다. 이중에서 한반도 고유종이 11분류군, 멸종우려 식물이 18분류군, 식물구계학적 특정식물인 IV-V등급 식물이 23분류 군이었다. 남방계식물은 4분류군, 북방계식물은 8분류군으로 조사되었고, 특히 남한 내 희귀식물인 갯활량나물(Thermopsis lupinoides), 기름당귀(Ligusticum hultenii), 벼룩아재비(Mitrasacme alsinoides), 통발(Utricularia australis), 검정납작골풀(Juncus fauriei), 새방울사초(Carex vesicaria), 천도미꾸리광이(Puccinellia kurilensis) 등이 동해안 석호에서 생육하고 있었다. 외래식물은 96분류군이 발견되었다. 한반도 석호는 식물다양성이 풍부하고, 희귀식물 및 식물지리학적 중요한 식물이 관찰된다. 석호의 효과적인 관리와 생물다양성 보전을 위해 체계적인 사항들이 논의되었다. Eastern coastal lagoons are a particular type of estuarine systems where seawater mixes with fresh water from their catchments. With the development of aquatic vegetation, this area shows high level of biodiversity. The purpose of this study is to produce a strategy for the comprehensive conservation of the vegetation of coastal lagoons through studies of the floristics and plant species compositions in 17 eastern coastal lagoons in Korea. Vascular plants were collected 109 times, from June of 2010 to November of 2014. The results showed that there were 720 taxa in total, including 118 families, 378 genera, 655 species, 13 subspecies, 46 varieties, and 6 hybrids. Korean endemic species numbered 11 taxa, and vascular plants listed in the red list according to the International Union for Conservation of Nature (IUCN) numbered 18 taxa. Indicator species of fourth (IV) and fifth (V) degree, as specified by floristic subregions, numbered 23 taxa. Among the species investigated in this survey, there were 4 taxa of plants of southern origin and 8 taxa of plants of northern originin the Korean peninsula. Several rare plants, Thermopsis lupinoides, Ligusticum hultenii, Mitrasacme alsinoides, Utricularia australis, Juncus fauriei, Carex vesicaria, and Puccinellia kurilensis, were distributed in eastern coastal lagoons. In all, 96 alien plants were recorded in the investigated area. The coastal lagoons on the eastern coast of Korea showed high plant diversity with many rare plants and phytogeographically important plants. Conservation strategies to ensure biodiversity and effective management of coastal lagoons are discussed in detail.

The factors influencing long-term prognosis of teeth must be carefully considered. Among these, attachment level is strongly associated with tooth loss. The purpose of the present study was to estimate pattern of attachment loss based on attachment area in extracted teeth. 197 satisfied the criteria for assessment after staining. The protocol described by Waerhaug(l975) was performed. An indir ect method, based on digital image abstracted from digital camera and digital imaging software program, was used to calculate the root surface area and the attachment loss area. The data were analysed using SPSS. Except maxillary central incisior and mandibular canine, no statistical significant differences between each root surfaces were observed in anterior teeth. In posterior teeth, statistical significant differences in palatal surface of maxillary molar and mandibular molar compared with others were observed. Statistical significant difference in buccal surface compared with others was lowly observed in single and multi rooted. This study did not reveal progressive loss pattern of attachment area in each root surface but clarified root surface that has relative high loss rate of attachment area at extraction. Thus understanding this pattern of attachment loss is helpful for dentist to treat the periodontitis.

An alien plant of unrecoreded Kickxia (Plantaginaceae) was found in Korea. K. eltine (L.) Dumort. was distirbuted in Yangju-si, Gyoenggi-do and Yeongcheon-si, Gyeongsangbuk-do. This species can be distinguished from the other related genera by having stems that trail along the groud without putting down roots, and the leaves are sagittate, or shaped like arrowheads with longer, narrower, pointed lobes opposite the shorter tip. The new Korean names is given, as ‘Hae-ran-cho-a-jae-bi’ to Kickxia elatine (L.) Dumort. Here, we provide precise description, illustrations, photographs and taxonomic key to related genera and species.

본 연구는 승마산의 관속식물상을 밝히고 주요 식물을 조사하였다. 2011년 3월부터 10월까지 총 13회에 걸쳐 수행되었다. 그 결과 관속식물은 94과 260속 340종 5아종 37변종 2품종으로 총 384분류군이 확인되었다. 한국 고유종은 외대으아리, 진달래, 개나리, 오동나무 등 9분류군이 확인되었다. IUCN 평가기준에 따른 희귀식물은 멸종위기종(CR)인 왕벚나무, 취약종(VU)인 삼지구엽초, 약관심종(LC)인 모새달이 조사되었다. 식물구계학적 특정식물종은 Ⅴ등급 2분류군, Ⅲ등급 2분류군, Ⅱ등급 1분류군, Ⅰ등급 10분류군 등 15분류군이 발견되었다. 생활형조성은 일년생식물(28.3%), 반지중식물(23.0%), 수생식물(14.3%)등이 높게 나타났다. 귀화식물은 43분류군으로 확인되었으며, 귀화율은 11.2%로 나타났다. 조사지역의 식생은 양호하나 최근 들어 인위적인 간섭에 의한 훼손이 증가되고 있다. 따라서 장기적인 모니터링을 통한 식생변화와 동태파악이 이루어져야 할 것으로 판단된다. This study was carried out to investigate the flora of Mt. Seoungma (Gyeonggi-do). The vascular plant were collected 13 times (from March to October 2011), and 384taxa in total were identified, including 94 families, 260 genera, 340 species, 5 subspecies, 37 varieties and 2 forms. Korean endemic plants of this area were nine taxa; Clematis brachyura, Rhododendron mucronulatum, Forsythia koreana, Paulownia coreana, etc. Rare plants (IUCN) by the Korean Forest Service and Korean National Arboretum three taxa were recorded; one Critically Endangered species (CR), Prunus yedoensis, one Vulnerable species (VU), Epimedium koreanum, one Least Concemed species (LC), Phacelurus latifolius. The floristic regional indicator plants found in this area were 15taxa comprising two taxa of gradeⅤ and Ⅲ, one taxa of grade Ⅱ, 10taxa of grade Ⅰ. Furthermore, therophytes (28.3%), hemicryptophytes (23.0%), hydrophytes (14.3%) showed high proportional ratio in life form spectrum. The naturalized plants were identified as 43taxa and the percent of naturalized index (NI) was 11.2% of total 384taxa vascular plants. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by the disturbances of human beings. Therefore, a long-term monitoring of vegetation changes and movement grasp must become accomplished.
