가뭄 전이는 기상학적 가뭄이 오랜기간 지속되어 수문학적 가뭄으로 발달하는 현상으로 가뭄 전이 사상은 비전이 가뭄사상보다 지역에 큰 피해를 야기한다. 기존에 수행된 가뭄 전이 연구들은 주로 상관분석을 통해 지체시간을 파악하고 있으며, 가뭄 전이 및 비전이 사상 간의 피해 양상을 비교하는 연구는 부족한 실정이다. 본 연구에서는 충청권역 시군구 단위의 가뭄지수를 활용하여 기상학적 및 수문학적 가뭄간의 중복전이 및 풀링전이를 고려하여 가뭄 전이 여부를 판단하고, 가뭄의 전이 특성(풀링, 감쇠, 지체, 연장)을 분석하였다. 분석 결과 충청북도 충주시에서 2010년 기상학적 가뭄(비전이 사상)이 발생하였으나, 가뭄 피해는 발생하지 않았다. 하지만, 2017-2018년에 발생한 가뭄은 기상학적 가뭄이 수문학적 가뭄으로 전이되면서 심도는 약하지만 지속기간이 길어짐에 따라 가뭄으로 인한 피해가 발생하였다. 이와 비슷하게 2017년 청양군에서는 기상학적 가뭄(비전이 사상)이 발생하였으나, 가뭄 피해는 발생하지 않았다. 하지만, 바로 인접지역인 부여군에서는 동일한 기간에 비슷한 크기의 기상학적 가뭄이 수문학적 가뭄으로 전이되어 가뭄으로 인한 피해가 발생하였다. 본 연구를 통해 비전이 사상보다 전이 사상에서 피해가 심각한 것을 확인하였으며, 이러한 결과는 지역에 적합한 가뭄 대응 정책을 수립하는데 기초자료로 활용할 수 있다. Sustained meteorological drought can lead to hydrological drought, known as drought propagation. The propagated droughts cause more damage to the region than the non-propagated droughts. Recent studies on drought propagation have focused on identifying the lag time using correlation analysis. There is a lack of studies comparing damage patterns between propagated and non-propagated droughts. In this study, the overlap and pooling propagation between meteorological and hydrological droughts were analyzed using drought indices in Chungcheong Province to identify drought propagation, and the propagation characteristics such as pooling, attenuation, lag and extension were analyzed. The results showed that although Chungju-si experienced a meteorological drought in 2010, no damage was caused by the drought. However, a meteorological drought in 2017 and 2018 propagated into a hydrological drought of longer duration but less severity, resulting in drought-affected damage. Similarly, Cheongyang-gun experienced a meteorological drought in 2017, but no damage was reported from the drought. However, in the neighboring county of Buyeo-gun, a meteorological drought with a similar magnitude propagated to a hydrological drought during the same period, resulting in drought-affected damage. The overall results indicated that the damage from propagated drought events was more severe than the non-propagated drought events, and these results can be used as basic data for establishing drought response policies suitable for the region.

Chronic exposure to high levels of manganese leads a pronounce and debilitating disorder known as manganism. Research on the toxic manifestation of manganese have focused primarily on its neurological effects because exposure to high levels of the metal produces a distinct and irreversible extrapyramidal dysfunction resembling the dystonic movements associated with Parkinson's physiological and biochemical systems in the body. The purpose of this study was to evaluate the effect of manganeses on primary rat calvarial cell growth and toxicity. The experimental groups were in concentration of 0, 10, 30, 60, 100, 300 ${\mu}M$. Cell activity was assessed at day 1 and day 3 using a fluorescent molecular probe. Cell proliferation was evaluated at day 1 and day 3 by MTT assay. The amount of total protein synthesis was measured at day 3 and day 7. The results were as follows: The proliferation of primary rat calvarial cells were inhibited by $MnCl_2$ in the concentration exceeding $100{\mu}M$. The primary rat calvarial cells treated with $MnCl_2$ showed similar protein synthesis to the control group except in 100 ${\mu}M$. These result suggest that manganese suppress the viability and protein synthesis of primary rat calvarial cells in concentration exceeding $100{\mu}M$.

The Ultra Fast Flash Observatory (UFFO) pathfinder consists of the UFFO Burst Alert X-ray Trigger telescope (UBAT) and the Slewing Mirror Telescope (SMT). They are controlled by the UFFO Data Acquisition system (UDAQ). The UBAT triggers Gamma-Ray Bursts(GRBs) and sends the position information to the SMT. The SMT slews the motorized mirror rapidly to the GRB position to take the UV/Optical data within a second after trigger. The UDAQ controls each instrument, communicates with the satellite, collects the data from UBAT and SMT, and transfers them to the satellite. Each instrument uses its own field programmable gates arrays (FPGA) for low power consumption and fast processing, and all functions are implemented in FPGAs without using microprocessors. The entire electronics system of the UFFO pathfinder including architecture, control, and data flow will be presented.

본 연구는 어머니-유아의 그림책 읽기 상호작용과 유아의 인쇄물 개념과의 관계를 살펴보고 인쇄물 개념에 영향을 미치는 상호작용의 유형을 알아보기 위해 서울에 소재한 유치원과 어린이집에 다니는 만 4-6세 유아 131명을 연구대상으로 선정하였다. 어머니-유아의 책읽기 상호작용을 조사하기 위해 곽아정(1994)이 수정하여 질문 형태로 만든 질문지를 사용하여 즉각적인, 비즉각적인, 생활지도성, 확장적 상호작용의 4가지 유형으로 분류하였고, 유아들의 인쇄물 개념을 알아보기 위해 “Concept About Print Test”(CAP, 2000)를 김선희(2004)가 수정ㆍ번안한 도구를 사용하였다. 수집된 자료에 대한 분석방법은 빈도, 백분율, t검증을 실시하였고, 어머니-유아 그림책 읽기 상호작용과 인쇄물 개념간의 관계를 알아보기 위해 Pearson 상관관계분석과 다중회귀분석을 실시하였다. 연구결과 첫째, 어머니-유아의 그림책 읽기 상호작용의 유형은 비즉각적인 상호작용이 가장 많이 나타났으며, 중상류층 어머니-유아가 저소득층 어머니-유아보다 확장적 상호작용을 더 많이 하는 것으로 나타났다. 둘째 인쇄물 개념의 하위영역 중 인쇄물 관례와 책에 대한 개념은 대부분 인지하고 있었다. 그러나 저소득층 가정의 유아보다 중상류층 가정의 유아가 더 높게 나타났다. 셋째, 어머니-유아의 그림책 읽기 상호작용과 인쇄물 개념간의 관계는 상호연관성이 높았으며, 상호작용의 유형 중 즉각적인 상호작용은 인쇄물 개념에 부정적인 영향을 미치는 것으로 나타났다 To examine relationships between mother-child reading interactions and concepts about print, samples of 131 children aged 4-6 years were selected from 6 preschools in Seoul. Instruments for measuring mother-child reading interactions were the Immediate, Non-Immediate, Organization, Extension scales of the Mother-child Reading Interactions, according to Kwack, and children’s Concepts about print were measured by the Concepts about print, based on Kim’s research. Data were analyzed by frequency, percentage, standard deviation, t-test, Pearson correlation, and regression analysis. Mother-child reading interactions correlated with children’s concepts about print. Immediate interactions were the worst predictor of concepts about print

We developed a four-channel first order gradiometer system to measure magnetoencephalogram for mice. We used double relaxation oscillation SQUID (DROS). The diameter of the pickup coil is 4 mm and the distance between the coils is 5 mm. Coil distance was designed to have good spatial resolution for a small mouse brain. We evaluated the current dipole localization confidence region for a mouse brain, using the spherical conductor model. The white noise of the measurement system was about 30 fT/$Hz^{1/2}$/cm when measured in a magnetically shielded room. We measured magnetic signal from a phantom having the same size of a mouse brain, which was filled with 0.9% saline solution. The results suggest that the developed system has a feasibility to study the functions of brain of small animals.

김지은,노영희,Kim, Ji Eun,Noh, Younghee 한국비블리아학회 2013 한국비블리아학회지 Vol.24 No.3

도서관마케팅에 대한 관심이 높아지고 있는 가운데, 국내외 도서관에서 SNS를 마케팅에 활용하는 사례가 늘어나고 있다. 이에 본 연구에서는 도서관 SNS 마케팅의 운영현황 및 문제점 분석을 기반으로 그 활성화방안을 모색하고자 하였다. 연구결과, 도서관마케팅과 도서관 SNS 마케팅에 대한 사서들의 인식은 높게 나타난 반면, 마케팅 전담인력의 부족, 마케팅교육의 부족, 낮은 도서관 SNS의 주당 평균 게시물 업로드 수 및 도서관 SNS 친구(팔로워) 수 등의 문제가 있는 것으로 나타났다. 이를 기반으로 본 연구에서는 도서관 SNS 마케팅을 지속 발전시키고 효과적인 도서관 SNS 운영을 위한 방안을 다섯 가지로 제시하였다. 첫째, 도서관마케팅 전담팀을 구성하여 효과적인 도서관 SNS 마케팅을 수행하게 하고, 둘째, 사서들의 마케팅 교육을 통해 실패없이 도서관 SNS를 운영하게 하며 셋째, 정기적인 자료 업데이트를 통하여 활발한 도서관 SNS를 운영해야 한다. 넷째, 이용자와의 커뮤니케이션을 통하여 이용자에게 필요한 서비스와 정보를 제공해야 하며, 다섯째, 각 SNS의 채널별 특징을 파악한 후 SNS를 효과적으로 운영할 수 있도록 해야 한다. With increasing interest in content marketing, SNS (social networking services) has become more popular as a method of library marketing, both at home and abroad. Accordingly, this study analyzed the operational status and problems of library SNS marketing, in an attempt to find ways to optimize its use. Results show that librarians' opinions of library marketing and library SNS marketing were very high, but the problems they faced included a lack of human resources dedicated to marketing, lack of marketing education, a lack of content to upload each week, and low numbers of contacts on social networking sites. To further develop and optimize library SNS marketing, five solutions were suggested based on the survey results: first, composing an intensive managing team for effective SNS operation; second, providing different levels of marketing training to decrease the librarians' mistakes; third, updating data continuously; fourth, providing information and services users need; and lastly, clearly identifying each channel's active operation goals.

The purpose of this study is to evaluate the effectiveness of online and offline blended education for hygiene and safety management of children's foodservice operations in Eunpyeong-gu. For the teachers of the children's foodservice operations, two online sessions and one offline session were conducted with different educational themes each time. In terms of satisfaction with the education, the online program 'Mission Possible' scored 4.8 points and the collective education of teachers and staff scored 4.6 points, indicating that the training composition and communication with the person in charge were high. In other field opinions, it was found that online and offline education according to the situation was very helpful in the overall management of the children's foodservice operations. With fewer face-to-face opportunities, there were difficulties in on-site support and management. To supplement this, various programs were applied to help children's foodservice operations provide healthy and safe meals and snacks.

김지은,권예지,나해란,이지은,노재흥,채정호,Kim, Ji-Eun,Kwon, Ye-Ji,Ran, Na-Hae,Lee, Ji-Eun,Noh, Jae-Heung,Chae, Jeong-Ho 대한불안의학회 2016 대한불안의학회지 Vol.12 No.1

Objective : The purpose of this study was to verify the differences of expressed character strengths graded as per the Korean Strength Scale, based on the type of work. Methods : A total of 2,444 conglomerate workers were classified into two groups: 1,356 office workers and 1,088 production workers. The subjects were examined through a web or mobile application based on the Korean Strength Scale. The Korean Strength Scale consists of a total of four top entries and 25 sub-items with appropriate validity. Results : The difference in the average score of sum of character strengths between the two groups was not significant. In the office worker group, character strengths such as love of learning, creativity, perspective, curiosity, facilitation, judgment and faith had significantly high scores. On the other hands, modesty, hope, gratitude, sincerity, magnanimity and self-regulation were high in the production worker group. The results remained unchanged in additional analysis of covariants as sex, age and education level, except for self-regulation and faith. Conclusion : Our results suggest significant differences in the character strengths between the two types of work; however, the average of sum of character strength score remains unchanged. These results may help to understand differences between work environments and thus help to establish a positive foundation.
