동굴은 우리의 옛 조상들이 강 가까운 동굴 속에 살면서 바닷가나 냇가에서 물고기를 잡아먹으며 살아가는 등 먼 옛날 석기시대에는 혈거생활의 주거지로 이용되어 왔을 뿐만 아니라 그 후 인류가 발전함에 따라 다양하게 이용되어 왔다. 즉, 때로는 은신처로 이용되어 왔고 때로는 묘지로, 작전기지로, 그리고 물자의 저장고로도 이용되었고 그밖에 수양터와 신앙의 장소 등으로 사용되었었다. 이러한 증거로서 인골화석, 생활을 위해 선조들이 사용하였던 다량의 도구 등 일상용품이 아직도 보존되어 남아있는 것이 발견되고 있다. 우리 나라에서 가장 독특한 문화를 갖고 있는 제주도에서도 여러 개의 동굴이 발견되었다. 이들은 성인상으로는 모두 제주도의 화산 폭발과 관련된 것이어서 용암동굴로 분류되고 있다. 그 중에서 삼성혈은 제주도의 삼성신화, 즉 부족 형성과 관련 있는 것이고, 빌레못동굴은 구석기시대에도 재주도가 주거지로 이용되었음을 인증 받는 중요한 자료로 활용되고 있다. 또한 김녕사굴의 설화는 재주도 설화의 하나로서 제주도 정부와 주민들간의 일치단결에 대한 예를 보여주고 있으며, 산방굴은 제주도 여인들의 기개에 대한 예를 나타내 주는 곳이고, 세계에서 가장 긴 동굴군계인 만장굴은 여인의 한을 전설로 담고 있다. 이렇듯이 동굴은 인류와 매우 밀접하게 관련되어 있음을 확인할 수 있다. 따라서 이제 동굴은 그 학술적ㆍ문화적 가치로서는 물론 최근에 붐이 일고 있는 관광적 측면에서도 그 보전 및 연구ㆍ개발이 시급하다 하겠다.

Prunus sargentii complex of subgenus Cerasus is an Eastem Asiatic plant group that exhibits a broad range of morphological variation and includes P. takesimensis, P. yedosensis, P. verecunda, and P. sargentii. In this study, a morphological analysis was undertaken to determine whether the observed morphological variation was primarily attributable to morphological discontinuities among the taxa. P. sargentii, which distributed eastem area in Korea, northern area in Japan and far east Russia had umbel like inflorescence and additionally was characterized by sticky bud and leaf twigs, compared with P. serrulata complex. Also, P. verecunda in Korea and Japan was characterized by umbel like inflorescence and presence of hair in leaf, petiole and pedicel, and was treated as a variety of P. sargentii. Evidence obtained from multivariate morphometric analyses indicated that the entity of P. takesimensis formed a cohesive group somewhat distinct from P. sargenti.. Especially, P. takesimensis was characterized by relatively small flowers (26-32mm in diameter) and many flowers [(2)3-5] per umbel inflorescence, compared with P. sargentii (34-48mm and 2(3) per inflorescence) and should be recognized as an independent and endeImic taxon in Korea. Additionally, P. yedosensis, which was known to have umbel inflorescence (short peduncle type) with pubescent style based on the type specimen, was comprised of corymb inflorescence (long peduncle type) as well. The morphological differentiation between these two types of P. yedosensis was not considered sufficient to warrant recognition of specific status because of the putative hybrid origin, no distinctive geographical distribution pattern, and existence of various peduncle length on Island Jeju-do of Korea.

One new naturalized species was recorded from Jeollanam-do Yeongam-gun, Daegu, and Daejeon in Korea. Hedyotis corymbosa grows well where there is enough sunlight; in moist, sandy soil. Hedyotis corymbosa (Rubiaceae) can be distinguished from other species in the same genus by longer peduncles, and a lot of flowers. We gave it the Korean name 'San-bang-back-un-pul' based on the specific epithet 'corymbosa'.

The petiole anatomy of three sections (sects. Calospira, Chamaedryon, and Spiraria) in the genus Spiraea (Rosaceae), which are distributed/cultivated in Korea, was studied and described in details. The vascular bundle system of the distal, medial, and proximal parts of the petiole were studied using LM with the aim of documenting any differences in vascular anatomy. Significant variation of anatomical characters was found in petiole shape (dichotomy, lens or subcircular in outline), presence of two distinct lateral wings, the thickness of epidermis, number of vascular bundles, length of ventral axis, length of dorsiventral axis, width of median vascular bundle, and length of median vascular bundle. All features were compared and we concluded that petiole anatomical characters can be useful for providing diagnostic features to distinguish the studied taxa. A key for identifying the Spiraea taxa in Korea based on their petiole anatomical characters is also provided.

A new spray chrysanthemum(Dendranthema grandiflorum) cultivar, "Golden Eye" was developed from a cross between "Rosa" and "Angaesoguk" by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services(ARES) from 2004 to 2008. Its characteristics were investigated three times from 2006 to 2008 under condition of forcing culture in spring and retarding culture in autumn. The natural flowering time of "Golden Eye" was October 23th, and year-round production was possible by day length treatment. This cultivar was yellow in color, single in flower type for the spray type cut flower. Its capitulum was 2.4cm in diameter, and had 23.2 head per stem in autumn. Its ray floret was green central zone. The days to flowering under the short day treatment is about 49 days in spring season, and "Golden Eye" showed the vase life of 25.7 days in autumn. This cultivar was registered for a commercialization in 2008.

This paper attempts to look at the identity of the traditional famous sceneries of Jeju Island by investigating the relationship between 'Yeoung Ju-Sipikyung(瀛州十二景)', which are the representative beautiful scenes of Jeju Island, and two paintings 'T'amna-Sipkyungtdo(耽羅十景圖)' and 'T'amna-Sullyokto(耽羅巡歷圖)' by a grasp of the contents and meanings of these two paintings. The following are the results of the study. In the 'T'amna-Sipkyung', which is the origin of today's 12 beautiful sceneries of Jeju Island, Baekrokdam and Youngsil are both symbolic places and the backdrops against which Jeju's myths were formed. Jocheonjin, Seogwijin and Myoungwoljin, located near the seashores, are strategic footholds in protecting the territory of the island and connotatively contain its culture and history. Seongsan Ilchulbong, Sanbangsan, Chwibyeongdam and Cheonjeyeon Pokpo are not only the quintessentially beautiful scenes of Jeju but also belong to 'YeoungJu-Sipikyung'. And 'T'amna-Sullyokto', which describes the Jeju horses and tangerines that were presented to the king as tribute, offers scenic elements with a strong political tone and is related to the five scene of 'T'amna-Sullyokto', showing that 'defense' and 'tribute' are motives in choosing the sceneries of people's daily lives here. Jeju's daily scenes in particular have been continuously transmitted: 'Idyllic lives with the background of a tangerine orchard' are shown in 'Kowon Panggo' and 'Kyullim P'ungak', and Jeju horses grazing on pastures or being ridden in hunting trips are presented in 'Sanjang Kuma' and 'Kyorae Taeryop'. Besides Baekrokdam and Youngsil, which do not belong to Sunyeok(巡歷) corridor of minister Lee Hyoungsang, 'Yeoung Ju-Sipikyung', directly related to 'T'amna-Sipkyung', has six beautiful sceneries: Seongsan of Seongsan Ilchulbong, Baekrokdam of Baekrokmanseol, Younggok of Youngsilgiam, Sanbang of Sanbanggulsa Chwibyeongdam of Yongyeonyabeom and Seogwiso of Seojinnoseong. The image of 'Gosumokma', the tenth landscape of 'Yeoung Ju-Sipikyung', was expressed as it is, through 'Udojeomma' and 'Sanjangguma'. The ten beautiful sceneries of 'T'amna-Sipkyung' were also especially described in 'T'amna-Sullyokto', besides Baekrokdam and Youngsil, which do not belong to Sunyeok corridor. As the places and landscapes emphasized on 'T'amna-Sipkyungto' and 'T'amna-Sullyokto' in common have been transmitted by the politicians and ancestors of Jeju Island, they have become established as today's 'Yeoung Ju-Sipikyung', passing through correction processes. When considering this process of development, 'Yeoung Ju-Sipikyung' are worthy of heritage and traditional landscapes accomplished in a long difficult period based on investigation into beautiful Jeju Island and the love of the island people for their home.

To examine the natural regeneration in the natural mixed-broadleaved forest, flowering, fruiting, seed-fall, and seed viabilities of Acer pseudosieboldianum (Ap) were investigated in Mt. Jungwang, Gangwon-do, from 2009 to 2015. The flower of Ap consisted many male and bisexual flowers on the corymb. Flowering dates are differed between sex morph in the same inflorescence. Stamens are stop growing and disappeared after pollinated pistil begin to grow in bisexual flowers, and male flowers have vestial pistil. The flowers of Ap might be pollinated by Apis mellifera, Andrenidae spp. and Syrphinae spp. Ap had some mechanism to prevent from self pollination with heterodichogamy. Mean annual seedfall of Ap was 70,780 ea/ha (ranged 310~234,840 ea/ha). Annual seedfall of Ap varied severely, and the maximum was about 760 times the minimum. Annual seed production of Ap might be to a normal distribution. Rates of damaged or decayed seeds are highest 59.3%, and those of sound seeds are 23.9%, Those of undeveloped and empty seeds are 9.2% and 7.6%, respectively. The most important factors influencing sound seed production might be the density and activities of insect pollinators and sucking pest in the flowerwing period, middle-late May. Successful regeneration of Ap might be in masting year and on the gap sites with proper conditions to germinate and grow. To understand the natural regeneration of deciduous hardwoods, further study on the characteristics of flowering and fruiting, pre- and post-dispersal seed predation, and annual variation on these factor should be needed.

The purpose of this study is to understand the idea of the ideal garden, pursued by Dasan, by analyzing the production process of his writing and the location of his dwelling, and the characteristics of the garden in the writings of Dasan (茶山) Jeong Yag-Yong (丁若鏞)'s "Jaehwangsangyuincheop (題黃裳幽人帖)" is concerned with his writings on an imaginary garden (意園). This paper assumed that "Jaehwangsangyuincheop" served as a blueprint for his ideal dwelling. The main research subjects are the external scenes described in the "Jaehwangsangyuincheop", and the garden elements and spatial construction that were visualized as a Korean Ink Painting (水墨畵) through the analysis of related works. The results are as follows. First, Hwang Sang was Dasan's favorite pupil, and "Jaehwangsangyuincheop" was written by Dasan while at Boeunsanbang in the winter of 1805 as an answer to a question that Hwang Sang posed about the residence of a hermit. By referring to this response, Hwang Sang established Ilsoksanbang (一粟山房) under Mt. Cheongae in Daegu-myeon, Gangjin. Secondly, the residence in "Jaehwangsangyuincheop" has mountains behind it and water in front of it (背山臨水). The residence was used as a place to combine life and leisure. It was an ideal residence that secluded the scholar(隱士). Thirdly, Dasan's ideal garden was shown as operation of natural geography in a residential location, practically using various plant materials, expanding physical boundaries of garden, pursuing synesthetic aesthetics while enjoying garden elements, and having an active experience of the taste for the arts in the extended garden. "Jaehwangsangyuincheop" depicted the life of a scholar with the taste of elegance (雅趣), who live in reclusiveness (隱逸), which was wanted by Dasan after exile. It was realized as Ilsoksanbang. "Jaehwangsangyuincheop" was interpreted as the ideal of a feasible dwelling that faithfully reflects Dasan's conceptual thoughts on the garden.
