한국의 지역별로 특화된 과학기술 연구개발과 투자가 지속적으로 강조되고 있다. 연구개발 특구로 지정도 확대되었다. 광역시도별 연구개발 투자가 확대되는 분위기에서 각 지역별 투자에 영향을 미치는 요인이 무엇인지 학술적 검토가 필요하다. 본 논문에서는 지수분해분석(Index Decomposition Analysis) 방법론을 적용하여 광역시도의 연구개발 투자 요인에 대한 분석을 시도하였다. 분석에 사용된 자료는 통계청에서 발행된 2010~2015년 동안 지역별 인구, 연구원수, 연구개발 투자비 등이다. 분석 결과 대전, 서울, 경기 지역의 연구개발 투자 증가가 두드러진 것으로 나타났으며 다른 지역은 상대적으로 낮은 것으로 나타났다.

2000년대 중반 세종 구구조 구문분석 말뭉치가 배포된 이후 의존 구문분석이 구문분석 연구의 주요 흐름으로 자리 잡으면서 많은 연구자들이 구구조 구문분석 말뭉치를 개별적으로 의존구조로 변환하여 구문분석 연구를 수행하였다. 하지만 한국어 문장의 의존구조 표현에 대한 논의가 부족하여 서로 다른 의존구조로 변환 후 구문분석을 연구함으로써 연구 효율성이 저하되는 문제가 발생하였다 본 연구에서는 이와 같은 문제에 접근하기 위하여 한국어 문장에 대한 의존관계 가이드라인을 제안한다. 그리고 제안하는 가이드라인을 기반으로 구축한 엑소브레인 언어분석 말뭉치(725 문장)에 대해 소개한다.

This study was conducted to evaluate the quality of meta-analysis of social work in South Korea using the Assessment of Multiple Systematic Review (AMSTAR). Electronic databases including the Korean Studies Information Service System (KISS), DBpia, and RISS4U were searched for 'meta-analysis', 'social work', and 'social welfare' from 2000 to December 2015, and 42 meta-analysis studies were included. Data were analyzed using descriptive statistics, t-tests, and ANOVA. The mean score for AMSTAR evaluation was $4.766{\pm}1.66$, while 19 studies (45.2%) were classified at the low-quality level, and 22 (52.4%) were at the moderate-quality level. The scores of quality assessment were analyzed by publication year, participants, number of studies included, number of DB, reporting study quality, extraction diagram and topics. The findings indicated that the following changes should be implemented to improve the quality and reliability of meta-analysis results in social work research: 1) common reporting guidelines should be provided for the social work field, 2) quality analyses of each study should be conducted to achieve a high level of evidence of effectiveness of social work interventions, 3) the characteristics of the included studies should be provided, and 4) a consensus and procedure based on at least two independent data extractors should be reported.

This study conducted time-series analysis on domestic studies related to entrepreneurship for more than last 50 years by integrating the co-word analysis method of intellectual structure analysis into the study of entrepreneurship. The co-word analysis method is a quantitative analysis method to analyze the overall trend of the study and further study topics by visualizing the information between study topics and arranging the topics on two-dimensional plane and the study result showed largely four phases and the direction of the study path. According to the analysis, the study is started at embryonic study phase(third quadrant), the study topic of independent study phase(second quadrant) is a phase to be a settled independent area as a study and the topics of the study include topics of the study reflecting the situation of the times. At growing study phase(first quadrant) study topics which are closely related to the study topic are arranged, and the topics, the center of the study, are positioned at the study topics of maturity phase(4th quadrant).

In Korea, there is a high demand for the operation of differentiated programs in basic research considering the characteristics of academic fields. The results of this study shows that the higher the level of research competence, the higher the quality of research outputs. The results also tell us that the quality level of the research outputs is different according to the field of study. Based on the results, we propose a method to differentiate the selection rate of each discipline in the system that operates the individual basic research projects by the level of research capacity.

In general, Area studies have very flexible field of research, so it is very difficult to proceed all field of research at the same time. Due to this, researches on Area studies have been changed the field of research and research trends according to age. So it is important to identify research trends for performing Area studies. Also, interests for understanding the research trend of Area studies are increasing constantly. In this paper, we analyze research trends of Mediterranean Area studies in Korea by using co-appearance keywords. To do this, we first analyze article types and extract co-appearance keywords on articles of 『Journal of Mediterranean Area Studies』, which is the representative journal of Mediterranean region in Korea. In details, trends analysis of Mediterranean Area studies would be performed by using cp-keywords of article and visualizing network graph forms.

Give that statistical analysis is an essential component of foodservice-related research, the purpose of this review is to analyse research trends of statistical methods applied to foodservice-related research. To achieve these objective, this study carried out a content analysis on a total of 251 out of 415 research articles published in The Korean Journal of Culinary Research(TKJCR) from January 2010 to December 2013. Of the total 164 research articles focussing on natural science research, qualitative research, articles written in English were excluded from the scope of this study. The results of this study are as follows. First, it turned out that 269 research articles applied quantitative research methods, and only 10 articles applied qualitative research methods among the 279 research articles based on social science research methods. Second, 20 article (8.0%) among the 251 did not specify the statistical methods or computer programs that were used for statistical analysis. Third, it was found that 228 articles (90.8%) used the SPSS program for data analysis. Fourth, in terms of frequency of use, it was revealed frequency analysis was most used, followed in order by reliability analysis, exploratory factor analysis, correlation analysis, regression analysis, structural equation modeling, confirmatory factor analysis, t-test, variance analysis, and cross tabs analysis, However, 3 out of 56 research articles that used a t-test did not suggest a t-value. 10 out of 64 articles that used ANOVA and demonstrated a significant difference in between-group mean did not conducted post-hoc test. Therefore, the researchers with interest in foodservice fields need to keep in mind that choosing and applying the correct statistical technique both determine the value and the success or failure of a study. To enhance the value and success of a study, it is necessary to use the proper statistical technique in an efficient way in order to prevent statistical errors.

This study was conducted to analyze the trend of quantitative research regarding female North Korean refugees in order to broaden our understanding of North Korean women and provide directions for future research. In August 2017, the Korean studies Information Service System (KISS) and Nuri Media (DBpia) databases were used to search academic peer reviewed journal articles with the following keywords: "North Korean female", "North Korean female refugees" and "North Korean female defectors". Trend analysis included a content analysis of the study finding section, along with analysis of the general characteristics of the study such as published journals, year of publication, study methodologies, and subject of the study. The main findings are as follows: First, Korean Journal of Woman Psychology was the journal with the most studies on female North Korean refugees. Second, as a result of looking at research trends by year, there was only one study on North Korean female refugees published between 2000 and 2004, and the number started to increase in 2010(8 articles, 22.22%). Third, according to the analysis of research trends by research methods, survey method was most frequently used. Fourth, statistical analysis was most often utilized analysis methodology(34 studies, 94.44%). Fifth, in the content analysis, North Korean female refugees' mental health and emotional issues(17 studies, 47.22%) were the most often the focus of studies being analyzed, followed by social adjustment issues((5 studies, 13.89%). Based on these results, directions for future studies were suggested.

현재 도시화로 인한 유출량의 증가 및 도달시간의 단축은 도시 재해의 한 원인이 되고 있으며 그에 따라 수공구조물에 대한 적정 설계가 필요하다. 하지만 계획단계에서부터 설계에 필요한 값을 예측하기는 매우 어려운 실정이다. 더구나 개발로 인해 매개변수가 변화함에 따라 유출 영향 분석이 어려울 뿐 아니라 이에 따른 연구가 미흡한 실정이기 때문에 모형매개변수의 민감도 분석을 통해 유출영향 분석 및 수공구조물 적정설계의 중요 기반자료로 활용하고자 본 연구를 수행하였다. 본 연구에서는 민감도 분석방법 중 절대 및 상대 민감도 분석 방법을 사용하여 각 유역의 지형학적 수문학적 매개변수들의 민감도 분석을 통해 상관관계를 확인하였다. 특히 대표적인 매개변수로서 유출계수 CN의 변화에 따른 유출량 및 유출 용적의 관계를 통해 CN의 증감에 따른 유출량 및 유출용적의 변화량을 산정하고, 또한 각 매개변수들간의 회귀분석을 통해 경험식을 작성, 제안하였다. 한편 현재 국내에서 사용중인 HEC-HMS를 모의하여 매개변수의 민감도 분석을 실시하였다. 본 연구의 결과로 CN값이 개발 전후 5% 증가시 유출량은 약 10%정도 증가한다는 것을 HEC-HMS모의와 자료의 분석을 통해 확인 할 수 있었다. 본 연구의 결과에 대해 검 보정 및 추가적인 자료수집을 통한 분석이 이루어지고, 매개변수 민감도 분석을 통한 국내 실정에 맞는 매개변수도출을 위한 연구가 계속적으로 수행된다면 미계측 유역에 대한 수공구조물의 적정설계에 상당부분 기여할 것으로 판단된다.
