가뭄은 수개월, 수년 이상에 걸쳐 서서히 발생 및 지속되며, 식생에 대한 피해가 발생할 때까지 확실한 인식이 어렵다. 최근에는 기후변화로 인하여 가뭄의 발생빈도가 증가하고 있으며, 기상 이상에 따른 다양한 형태의 가뭄이 발생하고 있다. 미국에서 정의한 'Flash Drought'는 비교적 짧은 기간 동안 표면온도의 상승과 비정상적으로 낮고 빠르게 감소하는 토양수분으로 인하여 식생에 대한 극심한 스트레스를 유발하면서 광범위한 작물 손실 및 용수공급 감소 등에 대한 피해를 야기하는 가뭄이다. 국내에서는 Flash Drought에 대한 모니터링이 활성화되지 않았기 때문에 본 연구에서는 '돌발가뭄'이라는 새로운 정의를 제시하면서 토양수분, 증발산량, 강수량, 기온 등의 가뭄 관련 주요인자를 활용하여 국내에서 발생한 돌발가뭄 (Flash Drought)를 감지하고 분석하고자 하였다. 돌발가뭄을 분석하기 위하여 선행연구에서 제시한 가뭄 관련 주요인자 기준 유형, 증발산량 기반 가뭄지수를 활용한 유형 등을 활용하였으며, 지상관측자료로는 국내 76개 종관기상관측 자료를 활용하였다. 또한, 토양수분 자료는 GRACE (Gravity Recovery and Climate Experiment) 위성영상 자료를 취득한 후 5 km 공간해상도 자료로 활용하였다. 가뭄지수의 경우 증발산 기반 가뭄지수 중 표준강수증발산지수 SPEI (Standardized Precipitation Evapotranspiration), 증발스트레스지수 ESI (Evaporative Stress Index) 등을 활용하여 국내 돌발가뭄 유형에 대한 분석에 적용하였다. 본 연구를 통하여 아직 명확하게 정의되지 않은 돌발가뭄에 대한 유형별 분석 및 국내 돌발가뭄의 수문기상학적 특성을 분석하고자 한다.

This study aims to explore the effect of quality factors and learning styles on users' satisfaction in the use of business simulation tools in business education. For this purpose, statistical methods such as reliability test, factor analysis, ANOVA, regression analysis were carried out using the survey data from university students. The quality factors of education using simulation were classified into contents, education environment, interpersonal activities, and instructor support while learning styles were classified into proactive, self-directed, environmental-dependent, and passive styles. The results showed that each quality factors of education using business simulation had a strong positive effect on user satisfaction. Proactive and environment-dependent group had higher satisfaction than other groups. Learning styles had moderating effects on the quality-satisfaction relationship, and the direction and degree varied depending on the quality factors and learning styles. Theoretical and practical implications were drawn from these findings.

This purpose of study is to identify types of study groups in online learning and the relationships between the types and teams' performance. In order to address these research questions, four study group types are developed based on Neiderman & Beise(1999)'s typology: 1) fully-supported; 2) highly-virtual; 3) traditional; and 4) inactive. And then three study group types are identified based on taxonomy-approach using cluster analysis from 46 teams participated in this study: 1) fully-supported; 2) traditional; 3), and 4) highly-virtual. The result shows that the groups are validated in the latter, except for the inactive type. The result indicates that fully-supported type groups achieved the highest performance, while the highly-virtual type group achieved the lowest performance.

Traditional models for categorizing researcher types have mostly utilized research output metrics. This study proposes a new model that classifies researchers based on the characteristics of research collaboration. The model uses only research collaboration indicators and does not rely on citation data, taking into account that citation impact is related to collaborative research. The model categorizes researchers into four types based on their collaborative research pattern and scope: Sparse & Wide (SW) type, Dense & Wide (DW) type, Dense & Narrow (DN) type, Sparse & Narrow (SN) type. When applied to the quantum metrology field, the proposed model was statistically verified to show differences in citation indicators and co-author network indicators according to the classified researcher types. The proposed researcher type classification model does not require citation information. Therefore, it is expected to be widely used in research management policies and research support services.

본 연구는 주부의 라이프스타일을 유형화하여 구분하고, 유형화된 라이프스타일에 따라 가정관리행동유형 및 가정생활만족에 차이가 있는지를 파악하여 주부의 가정생활의 질적 향상을 증진시킬수 있는 방안을 모색하고자 하였다. 라이프스타일을 알아보기 위해 주부의 태도, 관심, 의견(A.I.O)에 관해 요인분석과 클러스터 분석을 한 결과 우리나라 도시주부의 라이프스타일은 현대적향유형(28.1%), 보수전통주의형(26.3%), 건전활동형(21.5%), 소극적침체형(24%)으로 분류되었다. 주부의 관리행동유형은 대체로 변화지향적으로 나타났으며 학력이 높을수록 자녀수가 적을수록 변화지향적인 관리행동을 하는 것으로 나타났다. 주부의 가정생활만족도는 약간높게 나타났으며 라이프스타일에 따라 전반적인 가정관리행동유형은 의사소통과 계획의 융통성에 있어서는 변화지향적인 관리행동을 보이고 자원활용에서는 안정지향적이고 자원인식에서는 안정, 변화의 중립적인 관리행동을 하는 것으로나타났다. 라이 프스타일에 따라 가정생활만족도는 건전활동형이 높았으며 소극적 침체형이 가장 낮았다가 정관리행동유형이 가정생활만족도에 영향을 미치는데 의사소통, 자원활용 자원인식 등의 하위영역에서 변화지향적일수록 만족도가 높았다.

The purpose of this study is to see if reading guidances using the happy point books are effective. In this study, reading guidances were carried out to the 6th grade students of J Elementary School who have Enneagram Personality type 2. Books were selected as a source of reading guidance. These are self-growth theme books preferred by Enneagram Personality Type 4 students, a happy point of Enneagram Personality Type 2 students and books containing psychological functions of Enneagram Personality Type 4 students. A reading guidance was conducted in 14 sessions over a period of 5 weeks. Pre and post test using a measurement tool was implemented to measure the effectiveness of reading guidance in terms of emotional intelligence and self-esteem. And, written observation record cards and learning logs of the attendants were also made. As a result, the emotional intelligence and self-esteem of attendants appeared to be improved, and they are satisfied with reading guidance of applying to happy point books.

The purpose of this study is to compare existing player type theories using data clustering. For the study, 235 result data of the gamified class in second semester of A university at 2016 used. This study applied K-means and Silhouette to decide the appropriate number of clusters. The player types applied in this study are Bartle's 2-D and 3-D player types, Ferro's five types, and BrainHex. According to the results, Bartle's 2D player type was found to be the best in perspective of data clustering. This study also analyzed the distribution of characteristics for each player types. The results of this study are expected to have an impact on player analysis, which is used in the application of gamification or in the development process.

The purpose of this study was to synthesize the effects of the information literacy instruction using meta-analysis. Results using random-effect models were as follows. First, the overall average effect size (ES) of information literacy instruction (Hedges'g) was 0.72, which could be interpreted based on Cohen's guidelines as moderate to large. Second, the two types of information literacy instruction, demonstrating more than medium ESs, did not show significant differences in their ESs. Third, the ESs of information literacy instruction differed depending on the measuring variables. Fourth, grade, study design and the form of the measurement tool were moderator variables that explain the differences in ESs. In sum, the effects of information literacy instruction, having more than medium effect size, seem quite stable across instruction types and study designs.

The purpose of this study is to find out subjective perception types and needs of interested group on manpower training system with long-term care service by Q methodology, then to search for political measures to improve long-term care system in the implication of the sorted subjective perception types. The result of the study showed that there are five major sorts of subjectivities on manpower training system with long-term care service: emphasizes retraining of existing care worker(Type1), emphasizes ethics of public service provider(Type2), emphasizes practice-oriented education(Type3), emphasizes policy judgement of government(Type4), emphasizes training of long-term care worker in demand(Type5). And to try quantity approach methods, this study was developed Q-Block as a assessment tool to enhance validity and reliability of Q-types. The results of the survey showed high conformity.
