우리나라 최초의 과학영재학교인 한국과학영재학교의 과학교육을 위한 학습 지원 체제 및 학습 환경을 진단하고 그 유용성에 대한 학생들의 인식을 분석하였다. 이 조사를 위하여 자체 개발한 선다형 검사 문항을 사용하였으며 각 학년별로 학습 지원 체계의 효용성에 대한 인식의 차이를 조사하였다. 연구대상은 한국과학영재학교의 재학생 129명을 대상으로 설문 조사하였다. 연구결과로 첫째, 한국과학영재학교의 과학교육을 위한 학습 지원 체제는 대체로 유용한 것으로 나타났으며, 학생들은 교과수업, 인터넷활용, 실험 및 실습실, 독서실, 자연과학도서관, 연구회활동 및 동아리, AA(Academic Advisor)제도 , SAF(Science Academy Fair), 전자교재, 외부연사 초청특강의 순으로 유용성이 높다고 평가하였다. 둘째, 학생들이 추가로 희망하는 학습관련 지원으로는 교과교사의 학습방법 안내, 구두발표 능력 향상 프로그램, 온 오프라인 학습공동체 구축 등이 있었다. 이러한 결과는 과학영재의 잠재적 미성취 현상을 줄이고 학생들의 학교 부적응 상태를 호전시킬 수 있는 하나의 방안이 될 수 있을 것이다. 또한 학교 측면에서의 학습지원 체제를 개선하여 향후 고등학생 수준의 과학영재교육의 방향을 설정하는 데에 시사점을 제공 할 수 있을 것이다.

This paper presents the economic validity with the cost/benefit analysis on establishing R&D Supreme Academy. To evaluate the profitability of R&D Supreme Academy, willingness to pay (WTP) is measured by contingent valuation method (CVM) and then the net present value (NPV), internal rate of return (IRR) and benefit/cost ratio(BCR) are calculated. The results of economic evaluation verified that the establishment of R&D Supreme Academy is timely and effective in an economic perspective.

In this paper, we propose a transliteration approach based on semantic information (i.e., language origin and gender) which are automatically learnt from the person name, aiming to transliterate the person name of Uyghur into Chinese. The proposed approach integrates semantic scores (i.e., performance on language origin and gender detection) with general transliteration model and generates the semantic knowledge-based model which can produce the best candidate transliteration results. In the experiment, we use the datasets which contain the person names of different language origins: Uyghur and Chinese. The results show that the proposed semantic transliteration model substantially outperforms the general transliteration model and greatly improves the mean reciprocal rank (MRR) performance on two datasets, as well as aids in developing more efficient transliteration for named entities.

To develop a composition for enhancing immunity, based on alcohol extracts of the bumblebee as an active ingredient, bumblebee ethanol extracts were evaluated for their protective effect in chronic models of inflammation, adjuvant induced rat arthritis. B. terrestris worker extract (SDIEX) and, B. hypocrita sapporoensis lava and pupa extract (SPDYBEX), significantly decreased paw edema in arthritic rats, at a dose 100 mg/kg, respectively. The cytokine levels related inflammation of COX-2, $sPLA_2$, VEGF, and TNF-${\alpha}$, were decreased, compared to positive control, indomethacin (5 mg/kg). Histopathological data demonstrated decreases inflammatory activity, hind paw edema, and repaired hyaline articular cartilage in DRG over a 2 wk administration. HPLC and GC-MS analysis of SDIEX and SPDYBEX revealed the presence of cantharidin.

한국산 흑주름버섯속(Melanophyllum)의 종 다양성과 분포상을 조사하는 과정에서 2종이 확인되었고, M. eyrei는 국내 미기록종과 M. haematospermum은 기존 보고된 종이었다. 종 동정은 형태학적 현미경적 특징을 기초로 이루어졌고, 또한 ITS 염기서열 분석을 통해 이루어졌다. 미기록종은 '청흑주름버섯'으로 신칭하고, 기록종인 잔피막흑주름버섯은 종의 특징을 보완하였다.

We performed diagnostic PCR assays and a phylogenetic analysis using partial sequences of TEF1 (translation elongation factor-1) to determine the trichothecene chemotypes and genetic diversity of F. graminearum isolates from maize and rice samples collected in 2009 in Korea. PCR using a species-specific primer set revealed a total of 324 isolates belonging to the putative F. graminearum species complex. PCR with trichothecene chemotypespecific primers revealed that the nivalenol (NIV) chemotype was predominant among the fungal isolates from rice (95%) in all provinces examined. In contrast, the predominant chemotype among the corn isolates varied according to region. The deoxynivalenol (DON) chemotype was found more frequently (66%) than the NIV chemotype in Gangwon Province, whereas the NIV chemotype (70%) was predominant in Chungbuk Province. Phylogenetic analysis showed that all DON isolates examined were clustered into lineage 7, while the NIV isolates resided within lineage 6 (F. asiaticum). Compared with previous studies, the lineage 6 isolates in rice have been predominantly maintained in southern provinces, while the dominance of lineage 7 in maize has been evident in Gangwon at a slightly reduced level.

Agro-Meteorological Information Service (AMIS) network has been established since 2001 by Rural Development Administration (RDA) in Korea, and has provided access to current and historical weather data with useful information for agricultural activities. AMIS network includes 158 automated weather stations located mostly in farm region, with planning to increase by 200 stations until 2017. Agrometeorological information is disseminated via the web site (http://weather.rda.go.kr) to growers, researchers, and extension service officials. Our services will give enhanced information from observation data (temperature, precipitation, etc.) to application information, such as drought index, agro-climatic map, and early warning service. AMIS network of RDA will help the implementation of an early warning service for weather risk management.
