  • This study was conducted to investigate the effects of slow-releasing fertilizer and sowing date on waxy corn propagated through double cropping without tillage. "Mibaek 2" was sown for first cropping on March 25th, April 5th, and April 15th, and for second cropping on July 5th, July 15th, and July 25th in 2018-2019. In order to save labor, slow-releasing fertilizer was utilized only one time before sowing. The accumulated temperature from sowing to silking was about 590-700℃. It took 65-77 days when "Mibaek 2" was sown in early April, but the one sown in early July took 42-52 days. In the first cropping, the culm length and ear length caused by the sowing date had no statistical significance, but the kernel set length was the highest at 123 cm in the sowing district on April 5th. The weight of marketable ears was the highest at 100%, in addition to soil testing-based recommended fertilization. Meanwhile, in the second cropping, culm length, ear length, and yield were less compared to the first cropping. The culm length, kernel set length, ear length, and seed set length decreased as sowing date was delayed. The number and yield of marketable ears were the highest at 100%, in addition to soil testing-based recommended fertilization like in the first cropping. It has been found that securing yield by July 15th to finish the second seeding of the crop in the central part of Korea is advantageous. These results of this study will be helpful to farmers for the double cropping of waxy corn cultivation and management.

  • 'Maigic' 품종은 경남농업기술원 화훼연구소에서 복색 홑꽃인 'Artist Pink'를 모본, 복색 홑꽃인 'SP0347'을 부본으로 인공교배를 실시하여 2003년에서 2007년에 걸쳐서 파종과 계통선발을 통해 육성하였다. 품종의 특성검정은 2005년부터 2007년까지 봄 촉성재배와 가을 억제재배 조건아래서 3회에 걸쳐 조사하였다. 'Maigic' 품종의 자연개화기는 10월26일경이며, 일장조절에 의해 주년재배가 가능하다. 꽃 크기가 6.1 cm인 중륜화로 꽃 하나의 꽃잎수가 31.6개정도이고 착화수는 14개 정도이다. 화색은 복색(백색/자주색)이며, 녹색화심을 가졌다. 봄의 단일상태에서 'Maigic' 품종의 개화소요일수는 43일 정도로 개화가 빠르며, 가을의 절화수명은 20.6일로 나타났다.

  • 들깨는 식물성 오메가-3의 우수한 급원으로서 국내에서 그 수요가 크게 확대되고 있는 실정이다. 들깨 재배농가에서는 파종시기를 고려한 적합한 들깨 품종에 대한 요구가 많아 이를 해결하고자 중부지역에 적합한 품종을 선발하고자 시험을 수행하였다. 파종시기는 6월 상순, 6월 중순, 7월 초순 3시기로 구분하여 파종하였으며, 토양 검정시비량을 시비하고 완전임의배치법으로 3반복으로 시험구를 배치하였다. 시험품종으로 다유 등 10품종을 선정하여 시험하였다. 6월 초순 파종에서 개화기는 다실 품종이 8월 20일로 가장 빨랐으며, 다유, 대실, 들샘, 새엽실 품종이 9월 10일로 가장 늦었다. 6월 중순 파종에서 개화기는 다실 품종이 8월 27일로 가장 빨랐으며, 들샘 품종이 9월 11일로 가장 늦었다. 7월 초순 파종에서 개화기는 다실 품종이 8월 27일로 가장 빨랐으며, 들샘과 새엽실 품종이 9월 11일로 가장 늦었다. 들깨 천립중은 파종기가 늦어질수록 대체적으로 무거워지는 경향을 보였다. 6월 초순 파종에서 백진, 들향, 새엽실 다유 품종이 10a 당 110kg 이상의 수량을 나타냈으며, 6월 중순 파종에서 다유, 들향, 백진, 새엽실 품종이 10a 당 120kg 이상의 수량을 나타내었고, 7월 초순 파종에서는 다유, 들향, 새엽실 품종이 10a 당 110kg 이상의 수량을 나타내었다. 이상의 결과로부터 중부지역에서는 대체적으로 6월 중순 파종이 적합하였으며 전작물을 고려하여 들깨 파종시기를 빠르거나 늦게 할 경우에는 각 시기에 적합한 품종을 파종하면 안정적인 수량 확보가 가능하다. 중부지역에서 파종기에 따른 영향이 적고 안정적인 수량을 생산할 수 있는 품종으로는 다유, 들향, 새엽실 이었다. 이상의 결과로 부터 품종별 최대 수량을 얻기 위해서는 각 품종에 맞는 파종기를 준수하여야 할 것으로 사료되었다.

  • The objective of this study aims to explore the situation of damage from wild animals in Korea. Through case study on two villages in Injae, Kangwon province and Cheongyang, Chungnam province. This overview summarises the current issues and trends in wild animals damage through two case studies. We found that there are not only to get economic damage but also not to be able to sleep to protect their farm land from animal invading. We suggest to develop physical and chemical instruments not to access their plants in farmland and to increase central and local government's damage repayments.

  • Very recently, Rakha and Rathie obtained an extension of the classical Saalsch$\ddot{u}$tz's summation theorem. Here, in this paper, we first give an elementary proof of the extended Saalsch$\ddot{u}$tz's summation theorem. By employing it, we next present certain extenstions of Ramanujan's result and another result involving hypergeometric series. The results presented in this paper are simple, interesting and (potentially) useful.

  • Local resources can be employed as an original resource for local revitalization. This study has investigated the local resource, and then categorized these to suggest the implication available to the industrialization. Local resources were classified into 5 categories(with 25 subcategories), including remains and ruins, ethnic custom, manners and customs, people, traditional food and the principal product, and the natural ecology environment. Three phases were carried out in this study. We made lists of local resources and analyzed applicable resources among the lists. Also, we selected the target resources for the survey in Gimpo, and also analyzed the application for industrialization. Of all these resources, 560 cases were first investigated, then 51 local resources were in-depth analyzed. Based on this result, the application plan was investigated, dividing the central resources and the connection resources.

  • Recently several authors have extended the Gamma function, Beta function, the hypergeometric function, and the confluent hypergeometric function by using their integral representations and provided many interesting properties of their extended functions. Here we aim at giving further extensions of the abovementioned extended functions and investigating various formulas for the further extended functions in a systematic manner. Moreover, our extension of the Beta function is shown to be applied to Statistics and also our extensions find some connections with other special functions and polynomials such as Laguerre polynomials, Macdonald and Whittaker functions.

  • Since about 2000. local government has started making ordinance related to the rural development planning which is revitalizing rural area through using rural resource. But, the ordinance of local government have not any contents relating to the land use planning system that is necessary in rural development planning. According to the present local autonomy act, ordinance can not have any regulations restricting basic human right without being allowed by law. In recent, central government is considering to hand power making land use planning system over local government. This paper is to study how to expand the legislative power of local government. This study discussed on logical bases through examining disputes on legal theories, the nature of local ordinance, range of local autonomy affairs and cases of local ordinance.

  • Diffusion of non-professional flower growing in Korea still lags behind. The objectives of the study are to establish a theoretical modes to explain the diffusion of social floriculture, to identify some characteristics and problems of growing flower crops to cultivate amenities and emotions, and to suggest remedial measures for fostering it. Theoretical model adopted in this study consists of such variables as education, social movement, policies, diffusion of social flower growing, amenities, and emotional cultivation. For identifying the diffusion characteristics of flower growing, projects implemented by a non-governmental organization, schools, local and central government organizations were analyzed. In order to stimulate the diffusion of social flower growing and to increase its effects, there needs to strengthen education of stakeholders, establishment of partnership among schools, non-governmental and governmental organizations, and institutional supports including manpower and finances. Linking flower growing projects to community festival and tourism development programs can foster institutionalization of community flower growing. Furthermore, the introduction of wild, symbolic and traditional flowers and trees will help to specialize and improve community landscapes.
