This study has analyzed the trend of the quantitative research by analyzing domestic dissertations on information literacy that were published since 2000. The procedures, regulations, and descriptive elements of the quantitative study were compared and analyzed for this study. In addition, the study used 5 variables and criterions to measure these items. Based on the calculations, the study has examined the general characteristics of the thesis, research method, sampling method and sampling population of the dissertations. The study has also analyzed the trend of the measurement variables by categorizing the characteristics by published year and majors. Furthermore, the study has also presented the trend of the usage of statistic analysis method on research purpose by classifying the method into each purpose.

This study examined the prevalence of the assorted vegetables with beef on skewers called Hwayangjeok recorded in 16 Joseon dynasty (1392-1909) royal palace studies. The ingredients used in Hwayangjeok during the Joseon dynasty were categorized into 35.2% Hwangjeok(黃炙) & Jabjeok(雜炙), 16.7% Hwangjeokhwayangjeok(黃炙花陽炙), each 11.1% Saengboghwayangjeok(生鰒花陽炙) & Lagjehwayangjeok(絡蹄花陽炙), 9.3% Eohwayangjeok(魚花陽炙), 5.6% Donggwahwayangjeok(冬苽花陽炙), each 3.7% Cheonyeobhwayangjeok((千葉花陽炙) & Yanghwayangjeok1, each 1.8% Gyelan-eoeumjeok (鷄卵於音炙) & Ablanhwayangjeok(鴨卵花陽炙). Through this study, through new lighting and menu development for Hwayangjeok used as a basis for hope to contribute to the globalization of Korean food.

In theory, mixed methods that incorporate both quantitative and qualitative approaches can maximize strengths of each method while minimize the short comings of each. Mixed methods research is a feature of educational research nowadays, and the number of studies applied mixed methods research has been gradually increasing. This study investigates how mixed methods research was applied in the field of mathematic education, especially focusing on how qualitative and quantitative methods are combined to best address their research questions. With this in mind, this study carefully selects and analyzes 4 research articles that used mixed methods and were published by Journal of Elementary Mathematics Education in Korea in 2015. This study provides detailed result of qualitative analysis on mixed methods research while other a few previous analysis on mixed methods research were tend to focusing on quantitative analysis, producing numeric quantitative information. The result of this study provides practical and in-depth analysis on how to improve validity and possibility of mixed methods research, addressing alternative ways to combine two different research methods and key elements to take into account.

질적인 측면을 충분히 감안하지 못한 양적 성과분석은 연구개발 과제의 성과를 제대로 반영하지 못하는 문제점을 안고 있다. 따라서 양적 성과와 질적 성과를 함께 종합적으로 고려할 수 있는 종합적인 성과분석지수를 개발할 필요가 있다. 본 연구에서는 주성분 분석과 동일 가중치를 부여하는 방식을 이용하여, 특허 출원 건수, SCI 게재논문 건수, 기술이전 건수라는 3가지 양적 성과지표와 이에 대응되는 특허 심사청구 항수, 논문게재 학술지의 IT, 총 연구비 대비기술료 비중의 3가지 질적 성과지표를 성과지표로 고려하면서 성과분석지수를 개발하고자 하였다. 주성분 분석의 적용 결과 특허 출원 건수(0.2160), SCI 논문게재 건수(0.1510), 기술이전 건수(0.1564), 특허 심사청구 항수(0.2257), 논문게재 학술지의 IF(0.2218), 기술료 비중(0.0291)의 가중치를 얻을 수 있었다. 이 6가지 평가지표는 종합평가지수라는 하나의 틀로 결합되어 개별 과제의 성과를 평가하는 데 활용될 수 있다. 더 나아가 양적 성과지표와 질적 성과지표로 구분하여 평가할 수 있다. 가중치 결정 방법에 따라 평가결과가 크게 달라지지는 않았지만, 가중치 결정 방법과 상관없이 양적 성과지표 평가결과와 질적 성과지표 평가결과는 크게 달랐다. 한 가지 흥미로운 점은 과제평가등급과의 상관관계를 따져보았더니 질적 성과지표와 과제등급과의 상관관계가 양적 성과지표와 과제등급과의 상관관계보다 더 크다는 것이다. 따라서 성과분석에 있어서 질적 성과지표를 반영한 질적 성과분석이 반드시 수행될 필요가 있다. 앞으로 특허 인용도 등 보다 다양한 질적 변수를 확보하여 성과분석지수를 보완할 필요가 있을 것이다.

양적속성의 추정을 위한 확률화응답기법은 Greenberg et al.(1971)로부터 시작된다. 이후 새로운 방법에 대한 제시(Dalenius와 Vitale(1974)) 및 분포함수에 대한 추정(Duffy와 Waterton(1984))등이 연구되어 오고 있다. 본 연구에서는 2단계 확률화응답기법을 이용하여 양적속성을 추정하는 방법을 제시하고 이의 효율성 비교를 행해 보고자 한다.

The paper introduces trends and methodological challenges of quantitative Korean text analysis by using the case studies of academic and news media articles on "migration" and "immigration" within the periods of 2017-2019. The quantitative text analysis based on natural language processing technology (NLP) and this became an essential tool for social science. It is a part of data science that converts documents into structured data and performs hypothesis discovery and verification as the data and visualize data. Furthermore, we examed the commonly applied social scientific statistical models of quantitative text analysis by using Natural Language Processing (NLP) with R programming and Quanteda.

We augment an unrelated quantitative attribute to Bar-Lev et al.'s model (2004) which is composed of sensitive quantitative variable and scrambled one to present a multiplicative unrelated quantitative randomized response model(MUQ RRM). We also establish theoretical grounds to estimate the sensitive quantitative attribute according to circumstances irrespective of known or unknown unrelated quantitative attribute. Finally, we explore the relationship among the suggested model, Eichhorn-Hayre model, Bar-Lev et al.'s model and Gjestvang-Singh's model, and compare the efficiency of our model with Bar-Lev et al.'s model.

The purpose of this study was to investigate the trends of studying on job crafting in Korea and explore the future direction of studying on job crafting. For this purpose, this study selected KCI indexed 61 empirical studies which are published by end of August 2019. Through the analyzing on these 61 empirical articles on job crafting, this study tried to show the trends about Korean translation of 'job crafting', measurement scale, dimensions, and related variables. The results showed that mostly empirical studies on job crafting have been conducted after 2015. The academic field of those studies are mainly in psychology, human resource development, human resource management and tourism. The study results identified also there are various translated Korean terminology for 'job crafting' in Korean empirical studies. Regarding the measurement scale, the fact that Job Crafting Questionnaire and Job Crafting Scale has been mostly used was found. The results showed that the job crafting has been used equally as independent, dependent, and mediator variables. Finally, the empirical studies on job crafting in Korea have identified 48 predictors and 29 research variables that were predicted by job crafting. Among those variables, several ones have been used as a predictor and a variable which is affected by job crafting based on study settings. Based on the study results, theoretical and practical implications are suggested for future studies.

This study analyzed the types of quantitative reasoning and the characteristics of representation in order to figure out the characteristics of quantitative reasoning of the sixth graders. Three students who used quantitative reasoning in solving problems were interviewed in depth. Results showed that the three students used two types of quantitative reasoning, that is difference reasoning and multiplicative reasoning. They used qualitatively different quantitative reasoning, which had a great impact on their problem-solving strategy. Students used symbolic, linguistic and visual representations. Particularly, they used visual representations to represent quantities and relations between quantities included in the problem situation, and to deduce a new relation between quantities. This result implies that visual representation plays a prominent role in quantitative reasoning. This paper included several implications on quantitative reasoning and quantitative approach related to early algebra education.

그래프는 전산학의 주요 주제 중 하나이며 World Wide Web과 Social Network의 중요성이 커지면서 더욱 주목을 받고 있다. 그래프와 관련하여 그래프 데이터베이스에 대한 질의 모델에 관한 연구도 중요하게 다투어져 왔다. 하지만 이들 연구는 패턴 매칭을 통한 질의를 주로 다루었다. 하지만 그래프 데이터를 추천이나 검색 등의 응용하기 위해서는 PageRank 등 그래프 내의 연결 구조를 양으로 분석해내는 작업이 요구된다. 또한 SimRank 및 Random Walk with Restart 등 다양한 양적 분석 측도가 제안되고 있다. 이에 따라 본 연구에서는 Random Walk를 기반으로 하는 그래프에 대한 유연한 양적 분석을 지원하는 질의 언어를 제시한다. 또한 기존의 양적 분석 측도들이 본 질의 모델을 통하여 어떻게 표현되는지를 통하여 본 질의 모델의 유용성 및 확장성을 보인다.
