  • Universal characteristics of ginseng replanting problems appeared to be decrease in root yields due to root rot and inhibition of root growth. Incitants of ginseng replanting problems have not been clearly elucidated, however, it appeared to be a complex phenomenon with several pathogenic soil microorganisms and environmental changes in the soil due to decomposition of ginseng debris such as rootlets and shoots. Decomposition of ginseng debris may cause direct or indirect damage to the root. The effect of conventional fungicide on the control of the problems has not been recognized. However, it has been suggested that treatment with soil fumigants may solve the problems. Meanwhile paddy-rice and ginseng rotation system appeared to be the best way of solving the problems so far.

  • One of the distinguishing features of late Jeosun s Hanshi (poem in Chinese) is the numerous creation of Yeonjachyung Keesokshi (serial poem on folklore) which describes the folk manner and folk way of life in detail. Keesokshi s subject matter is the folklike in general including local features, geography, climate, local production, humanity, social conducts, and daily labor for living as well. By its material characteristics, Keesokshi reflects detailed life conditions of the society members in each levels, and represents the local customs as well as the folk emotions. Among the several kinds of Keesokshis, a Sesi Keesokshi focuses only in reciting the folk customs on each seasonal festival days, and the great numbers of such serial poems appear during the latter part of the Jeosun Dynasty. Its overall background is the transition of artistic trend which came after many social changes such as expansion of realism, uprising national consciousness, shaken status system, and the rising of 'Jeosun si motives in the Hansi history. Moreover, each writers various experiences and their interests in the reality and critical minds of common people contributed a crucial roll in creation of Sesi Keesokshi. 178 of the 584 remaining serial Sesi Keesokshi are written particularly about the folk customs in The Grand Full Moon Festival (the first full moon of a year by the lunar calendar). These Hanshis widely reflect the common ways of living by directly accepting the seasonal folk customs as the subject matters. Especially, close to the reality, these poems positively express the people's simple vigorous lives and create unrestrained lively image by describing the joys and sorrows of the folk ewistence along with their craving. Also, it is notable to have customs such as 'Shil-Ssa-Um' and 'No-gu-ban-kong-yang' as subjects for its rarity in other literatures.

  • This study was carried out to investigate the effect on the system of crop rotation of sesame(Sesamum indicum L). The results of infected plant percentage and yield of sesame wilting disease, fluctuation of density of Fusarium oxysporum and Actinomycetes, and their pathogenicity test on Fusarium spp isolated from sesame cultural soil were investigated. Density of F. oxysporum was the highest in a sesame continuous cropping soil but that of Actinomycetes was the lowest in that soil. And that of F. oxysporum and Actinomycetes according to investigation date was the highest at June. 30 and July. 30, respectively. Their pathogenicity of F. oxysporum and F. solani isolated from sesame cultural soil to sesame, peanut and green gram were recognized to all isolates except one isolate among F. oxysporum 8 isolates and one isolate to sesame, 2 isolates to peanut and all isolates to green gram among F. solani 4 isolates. F. oxysporum density and infected plant of wilting disease were increased as a result of replanted cultivation of sesame, and yield of that was prominantly reduced. Relation between density of F. oxysporum in cultural soil and infected plant percentage showed positive correlation and yield index highly negative. There was little difference between sesame-upland rice and sesame-peanut in the system of crop rotation.

  • In this study, we will find out and understand of the literary characteristics and the material status about the translation of Sijo into chinese poetry which is the representative genre in Korean traditional poetry. Most of the work was done from 17th 19th century, and there are about 120 literary men who translated Sijo. 759 works are translated into Chinese poetry and we cannot find 135 works' original poetry. Therefore about 900 works are translated into Chinese poetry. One Sijo can be translated into more than 1 Chinese poetry, so there are more translated works. According to this study, there are 1356 translated works in total. Many works are done in piece by piece, however most of them are in series with many poems from 10 to 100. First, some popular Sijo was translated into series. Second, some serial Sijo or some Sijo of particular writers are translated into Chinese works. In first case, there are 22 writers' 27 works of Sijo along with Shinwi's "Soakbu" and 652 translated works. In the other case, there are 30 writers' 26 works of Sijo including 10 "Kosangugokga", which was translated by Song shiyul. There are 511 translated works. A lot of translations of Sijo into Chinese poetry are in various documents. They are in personal collections of works such as "Beonbanggok" in Namguman's "Yakchunjip". The works are in books of poems such as Hong yangho's "Chunggudangok" and Shinwi's "Jahasoakbu". In collection of Sijo like Shin heum's "Bangongshiyeo" in "Chungguyoungwon", there are some translated works as well. We can understand Sijo which we do not know the lyrics now by studying the materials about the translation of Sijo into Chinese poetry. The materials about the translation of Sijo into Chinese poetry have necessary value for studying the creation and tradition process of Sijo. In addition, with the materials, we can study the interaction between Korean literature and Chinese one, and also we can study about the changing aspects of Chinese poetry in Late Chosun.

  • 우리나라의 경우 각종 장해와 주년 수요의 증가에 따른 불시재배의 증가로 인하여 저온신장성, 병해저항성 등과 같이 작물의 내성증진을 목적으로 접목묘의 이용이 급속도로 신장되고 있다. 특시 연작장해가 심한 박과형 채소류는 대부분 접목재배가 필요한 실정이다. 그러나 국내의 경우, 접목작업은 거의 수작업으로 행해지며 세밀한 조작과 숙련성 그리고 많은 노력을 필요로 한다. 따라서, 접목 생산성을 높일 수 있는 저가의 자동화 시스템 개발이 요구된다. 다양한 접목법들 중 현재 농가에서 가장 광범위하게 이용되고 있는 호접은 삽접 및 절단접에 비하여 자동화가 어렵고 활착 후 절단작업이 부가적으로 필요하나 접목 후 순화공정이 간단하고 활착률이 높다. 본 논문에서는 호접과 삽접에 대하여 접목 후의 활착률 및 접목에 소요되는 작업시간을 비교하였고, 호접법에 의거하여 작업공정을 생력화한 육묘 자동접목 시작기를 개발하였다. 시작기는 농가조합 및 중규모 육묘장의 설비를 지향하여, 묘판 및 접목묘의 취급을 제외하고 1인 접목작업 형태의 자동화 시스템으로 개발하였다. 시작기는 크게 버퍼기능을 부착한 배치형 육묘장치부, 2세트에 공압 매니퓰레이터, 대목과 접수의 원할한 접목을 위해 설계한 특수 그리퍼, 각고 조절형 절단부, 진동형 클립공급부 그리고 자동 클립 장착장치로 구성하였다. 접목 작업시간은 대략 4ch 정도이나 작업시간의 조정이 가능하도록 하였다. 실험실에서 수행한 간이접목 시험 결과, 절단날이 대목과 접수의 접촉부위를 관통할 때 접촉면이 서로 어긋나는 경우가 발생하였으나 육묘들이 호접에 적정한 기하학적 물성 요건을 갖춘다면 80% 이상의 접목 육묘의 기하학적 물성에 따른 체계적인 접목시험이 필요하다.

  • (傳說의 故鄕) is a broadcast play as one-act play series based on Korean legends and folktales. It was first aired in 1977 from KBS and there has been borrowed from this play in a variety of genres such as books and movies as the name of this series securing its popularity and awareness of the public. In this context, this is a representative work for Korean horror genre. Recently, for example, a series webtoon <2013 Home of the Legends> is published on one of the main portal websites, NAVER from July, 2013. This webtoon is main subject of this study. The purpose of this study is to discuss how the genre characteristics of Korean horror in TV serial play transmitted and changed in series webtoon <2013 Home of the Legends>. TV serial play is a representative narrative based on Korean folktales, trying to change its narrative in the range of undestroyed folktale basic move with combining the original motifs. Serial webtoon <2013 Home of the Legends>, however, deconstructs this combination motif in folktale form and leads to new move in narrative. For Korean users accustomed to Korean folktale form as the architext, this will be expected as reversal and make catharsis. Meanwhile, the deconstruction of combination motif leads to extinction of its cause-and-effect, which consists the axis of original narrative form, with resulting powerless theme, good overcoming evil and punitive justice. The aspects of changes in <2013 Home of the Legends> represent new orientation of Korean horror.

  • The disease incidence rates of Phytophthora root rot of A. macrocephala caused by P. drechsleri were dramatically increased in two distinctive periods at experimental fields of National Crop Experiment Station(NCES), Suwon, in 1999 and in 2000 ; one was in the period of 30 to 45 days old seedling stage in spring and the other was just after heavy rainy season in late summer or in early fall. The disease was occurred at seedling stage under the conditions of ${{\geq}15^{\circ}C}$ of average temperature with ${{\geq}100mm}$ rainfalls for 20 days and the tendencies were similar in both year. By the disease, rhizome propagated field was more damaged(18.6%) than seed propagated field(56.0%). Comparing the disease incidence rates at five different fields in Suwon, Youngju and Andong, the damages at soil improving fields and non-mulching fields were less severe than those at continuous cropping fields without soil improvement and mulching fields and occurrence. Expansion of the disease were seemed to be highly related with the populations of P. drechsleri in soils depend on the cultivation method and field conditions. Although the populations of the pathogen in soils collected from Andong and Youngju, in which rhizome were continuously propagated for two and three years respectively, were comparably less than that from Suwon, in which rhizome were propagated for one year, however, the damages by the disease were more severe in Andong and Youngju. So, two or more years of cultivation at the same field may not be useful for Atractylodes plants..
