The potential cultivation of buckwheat species in Luang Prabang region, Lao PDR where the species has not been naturally grown and not traditionally utilized was studied to introduce buckwheat as a new agricultural material, especially for food and medicine. The growth of Tartary buckwheat species was higher than common buckwheat showing 2.3 fold of plant height compared to common buckwheat. Number of flower per plant in Tartary buckwheat (731) was three fold higher than common buckwheat (244). Dry weight per plant was respectively 1.7 g in Suwon No. 1, 2.6 g in Suwon No. 2, and 1.4 g in KW45. The rate average of seed setting was similar between common buckwheat (41 to 46 %) and Tartary buckwheat (44%). Total seed yield of Tartary buckwheat (184 kg/10 a) in 10a could be estimated to be higher than that of common buckwheat (108 kg/10 a).

전 세계적으로 기후변화로 인한 자연재해가 빈번하게 발생함에 따라 수자원 분야에서 또한 환경의 변화에 대한 정확한 예측이 더욱 요구되고 있다. 국내에서도 이를 위하여 다양한 방법을 통하여 연구가 이루어지고 있으나 본 연구에서 사용된 Common Land Model (CLM)은 국내에서의 실질적인 적용이 아직 부족하다. 이 모형은 Soil-Vegetation-Atmosphere Transfer 모형 중 대표적 모델로 Land Surface Model (LSM), Biosphere-Atmosphere Transfer Scheme (BATS), Chinese Academy of Sciences Institute of Atmospheric Physics LSM의 세 모형이 결합되어 발전하였다. CLM의 강제입력자료로는 위성, 지면모형 등을 기반으로 만들어진 자료를 제공하는 Korea Land Data Assimilation Systme (KLDAS; 한반도지표자료동화체계)의 격자화 된 자료를 사용하여 모형에 강제시켰다. KLDAS는 기존의 Land Data Assimilation System (LDAS)에서 발전한 형태로 동아시아 지역을 대상으로 자료를 제공하고 있으며, 본 연구에서는 이 자료를 사용하여 국내 전반에 걸쳐 격자에 대한 수문 기상학적 인자를 산출하였다.

Using artificial neural network (ANN) technique, auction prices for common mackerel were forecasted with the daily total sale and auction price data at the Busan Cooperative Fish Market before introducing Total Allowable Catch (TAC) system, when catch data had no limit in Korea. Virtual input data produced from actual data were used to improve the accuracy of prediction and the suitable neural network was induced for the prediction. We tested 35 networks to be retained 10, and found good performance network with regression ratio of 0.904 and determination coefficient of 0.695. There were significant variations between training and verification errors in this network. Ideally, it should require more training cases to avoid over-learning, which leads to improve performance and makes the results more reliable. And the precision of prediction was improved when environmental factors including physical and biological variables were added. This network for prediction of price and catch was considered to be applicable for other fishes.

This study aims to suggest the ways to apply Information Commons to local university libraries, which face various changes in users and information environment, for using the libraries' space more effectively and for providing users with more satisfying services. Information Commons, which is a concept having been gradually spreading mainly in the U.S. from the early 1990's, is a service place where users can work out anything related to their studies or various lecture-related jobs because they are provided with various information and electronic resources in that one spot. Researches show that physical and human resources should be prepared before executing Information Commons to minimize the problems and to maximize the effectiveness from applying it. Physical resources are such as PC rooms, multimedia rooms, education rooms, one person or group study rooms, and cafe or lounge. Human resources are the librarians who can do reference services including giving the lectures on using library information resources and who can solve the operating problems related to IT.

The common squid $Todarodes$ $pacificus$ is a dominant species in Korean waters, where it is captured preponderantly by the angling fishery. The spawning and nursery grounds of $T.$ $pacificus$ extend from the southern East Sea to the northern East China Sea. Consequently, the environmental conditions in this area during the spawning and nursery seasons might affect the abundance of $T.$ $pacificus$. This study, analyzed the relationship between the distribution of zooplankton and the abundance of $T.$ $pacificus$ and variation in the squid angling fishing grounds in Korean waters. There was a positive relationship between the fluctuations in zooplankton and the catch per unit effort (CPUE; $kg{\cdot}day^{-1}{\cdot}person^{-1}$) of the angling fishery in the East Sea of Korea. The main fishing season is from July to December and the CPUE was closely related to the zooplankton biomass in April in the East Sea. Recently, the center of the squid jigging ground has moved drastically from the area around Ulleung Island to the northern East Sea. We postulate that the fishing grounds of the squid angling fishery will move farther north with climate change.
