In national prospective, the needs to develop water resources has been increased due to water shortage from diverse use of water resources in agricultural areas. Existing agricultural water demand, which has mainly been limited to the use of farming, are now expanding to diverse water uses such as supporting daily lives, diluting environmental pollution as well as industrial use for agricultural complex currently under construction in agricultural region. In this situation, for the sake of effective procurement of water resources and supply method, it is definitely required to enhance the effectiveness of budget investment and project proceedings through integrated re-development which links projects to strengthen existing dams, reservoirs and hydraulic facilities. The major scopes of this research includes developing different types of system such as selecting potential sites to re-construct reservoirs including generating base maps and thematic maps, data collection regarding water demands and reservoir status; analyzing reservoir data; estimating developable capacity and index calculation; and forecasting inundated areas. In addition, this study provides other products such as developing output generation system which can support wide use of data built and analyzed; database generation for better data management; data analysis including selection, extraction, indexation, and calculation of base items through standardization; data security system prohibiting exterior proliferation and malicious manufacturing of data.

This study is a preliminary study to develop an evaluation framework necessary for evaluating the DataON platform. The first objective is to examine expert perceptions of the level of DataON platform construction. The second objective is to evaluate the importance, stability, and usability of DataON platform features over OpenAIRE features. The third objective is to derive weights from the evaluation perspective for future DataON platform evaluation. The fourth objective is to examine the preferences of experts in each evaluation perspective and to derive unbiased evaluation criteria. This study used a survey method for potential stakeholders of the DataON platform. The survey included 12 professionals with at least 10 years of experience in the field. The 57 overall functions and services were measured at 3.1 out of 5 for importance. Stability was -0.07 point and usability was measured as -0.05 point. The 42 features and services scored 3.04 points in importance. Stability was -0.58 points and usability was -0.51 points. In particular, the stability and usability scores of the 42 functions and services provided as of 2018 were higher than the total functions were, which is attributed to the stable and user-friendly improvement after development. In terms of the weight of the evaluation point, the collection quality has the highest weight of 27%. Interface usability is then weighted 22%. Subsequently, service quality is weighted 19%, and finally system performance efficiency and user feedback solicitation are equally weighted 16%.

본 연구에서는 역학적으로 실질적이면서도 단순화된 방법으로 폭풍과 같은 악후시에 임의의 해안단면에서 발생하는 소상파의 수동학적 거동에 대한 예측모델을 개발하고자 한다. 실제 크기의 폭풍과 조건하에서 사구의 침식을 모의하기 위해 수행된 대형조파수조 실험에서 계측된 실험자료가 모델 개발을 위해서 활용된다. 일반적으로 본 모델은 해안종단방향에서의 소상파의 파고, 속도 및 주기의 변화를 예측할수 있음을 보인다. 정량적으로 보다 나은 소상파 변수들에 대한 예측은 유의 소상파고가 영이 되는 해빈면의 높이, ymax에 대한 예측향상을 통하여 이루어질수 있다.

Purpose: The purpose of this study is to identify the factors influencing COVID-19 infection prevention behavior of nursing students. Methods: Data collection is from December 17 to October 22, 2021. One hundred and ninety-seven nursing students participated in this study. Data were analyzed using an independent t-test, ANOVA, correlation coefficient, scheffé test, and multiple regression analysis. Results: COVID-19 knowledge (r=.49, p<.001), attitude (r=.41, p<.001), and COVID-19 risk perception (r=.40, p<.001) were related to COVID-19 infection prevention behaviors. The factors influencing COVID-19 preventive behaviors were identified as knowledge (𝛽=.28, p<.001), attitude (𝛽=.25, p<.001), risk perception (𝛽=.18, p=003), 2th grade (𝛽=.19, p=.011), 3th grade (𝛽=.21, p=.006), 4th grade (𝛽=.20, p=.008), and gender (𝛽=.12, p=.033). Conclusion: The results of this study can be used for the development of health policies suitable for community infectious disease prevention behaviors and the development of infectious disease educational intervention programs.

Actinomycetes 500계통 중 식물병원성 곰팡이(Alternaria alternata, Botryotinia fuckeliana, Colletotrichum acutatum, Colletotrichum gleosporioides, Corticium sasaki, Cylindrocarpon destructans, Fusarium oxysporium, Magnaporthe grisea, Phytophthora infestans, Phytium ultimum, Thanatephorus cucumeri)저해하는 균주를 선발하였다. CNU-A91231(Korea Agricultural Culture Collection #20938)이 식물병원성 곰팡이에 대한 억제 활성이 강한 것으로 나타났으며 16s rDNA sequence를 통해 Streptomyces griseofuscus로 동정 하였다. S. griseofuscus CNUA91231의 효율적인 배양을 위해 간단하고 실용적인 배지를 개발하였다. 이 균주의 최적 성장조건은 28, pH 6에서 aeration 조건이었다. Alanine, glutamine, proline, ammonium ion은 좋은 질소원이었다. 당밀에 Na, Cl, Ca, P, K, Mg를 첨가하였을 때는 S. griseofuscus.의 성장을 증가시키지 못하였다. 아미노산을 함유한 비료를 사용하였을 때 이 균주의 성장을 증가시켰다. 최적의 배지로서 당밀 + 1% glutamate 부산물 분말로 결정하였다. 최적 배지에서 S. griseofuscus의 배양은 이 균주의 antifungal 활성에 영향을 주지 않았다. 본 연구에서 연구된 bacterium과 배지가 작물재배에 생물학적 항 곰팡이 제재로 이용될 것으로 기대된다.

It is widely known that the public library in Korea has not been developed as a social agency which makes communication process possible. The public library in Korea just plays a role of the public study room for students using their own books. There is almost no public libraries in the sense of an open collection of comprehensive materials designed for use by anyone who seeks information. This study starts from this situation. It aims at identifying the present stage of the development of public libraries in Korea through investigating librarians' consciousness in their everyday lives. For this, a case study method is used for investingating, collecting and organizing the 'discourse' of librarians in Pusan and Kyongsangnamdo area. Major suggestions include : First of all, it is most important for public library reformation to eradicate the 'conservatism' in the consciousness of librarians in their everyday lives. So, it is essential to collect their life stories in various library conditions, and make them public discourse of librarians. Secondly, the professional organization should play a role to unify the librarians. For this role, it should maintain a R&D department and strengthen PR programs. Thirdly, Researchers who study Library and Information Science in Korea should be always concerned with the real-life context in the field. The most important type of research in our third world situation is the one that is based on the present stage of the development of our own libraries and the real library situation in the field.

5-Fluorouracil (5-FU) is an antimetabolite anticancer agent active against many types of solid tumors. Tegafur (TF), a prodrug of 5-FU, is frequently used in combination with uracil as dihydropyrimidine dehydrogenase (DPD) inhibitory fluoropyrimidine. We studied the stability of 5-FU and TF in biological fluids of rats and determined their bioavailability (BA) and excretion into bile, and urine. The drug concentrations were analyzed by an HPLC method. At room temperature, there was a 14-30% decrease in the concentration of 5-FU and TF in bile, urine, and plasma specimen at 10 and $100\;{\mu}g/ml$ over 240 min. No significant difference was noted among the sample types or between two different concentrations of 10 and $100{\mu}g/ml$. The decrease in drug concentration was significantly less in samples kept on ice (6-12%) for both drugs. These data indicate that biological fluid samples containing 5-FU or TF in plasma, urine, or bile should be placed on ice during the sample collection. Following these storage guidelines, samples were collected after administration 50 mg/kg of each drug via i.v. or oral route. BA was 1.5 folds greater for TF (60%) than that of 5-FU (42%). Approximately 0.52 and 3.3% of the i.v. doses of 5-FU and TF was excreted into bile, respectively. Renal clearance of 5-FU was about 16% of its total body clearance. These results suggest that instability of 5-FU and TF in biological fluids should be considered in pharmacokinetic or pharmacogenomic studies.
