The purpose of this study is identifying variables that affect to learners' preference toward specific e-learning programs, using an exploratory factor analysis(EFA) method. We extract common factors that explain the correlations among variables. In the result, 8 factors were identified as main influential factors: e-learning program design(1st factor), the purpose of e-learning use(2nd factor), social and cultural issues(3rd factor), demographics(4th factor), organizational needs(5th factor), impacts of e-learning(6th factor), e-learning management(7th factor), and technical issue(8th factor).

이 연구는 Hewitt과 Flett(1991c), 이기종(2006)이 제안한 완벽주의 척도 연구모형의 타당도를 확인적 요인분석을 통해 검증하고, Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 문항이 몇 개의 요인으로 구성되는지 알아보기 위해 탐색적 요인분석을 실시하였다. 확인적 요인분석 결과 Hewitt과 Flett(1991c), 이기종(2006)이 각각 제안한 연구모형과 수집된 자료가 잘 합치하지 않았다. 따라서 자료에 모형이 잘 맞도록 모형을 수정해야 하고, 의미 없는 자유모수가 모형에서 나타나지 않도록 모형을 다시 설정해야 함을 알 수 있다. 또한 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 탐색적 요인분석을 통해 완벽주의 척도의 각 문항들이 완벽주의를 측정하는데 있어서 단일요인으로 제 기능을 하기 보다는 여러 문항에 걸쳐 공통요인이 존재함을 알 수 있다. 따라서 확인적 요인분석과 탐색적 요인분석을 통해 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도가 측정하는 요인은 3개 요인으로 설명될 수 없다고 판단된다. 그러므로 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 측정 문항이 수정되어야 하고, 나가서 우리의 사회 문화적 실정을 고려한 완벽주의 척도의 개발이 시급함을 알 수 있다.

본 연구의 목적은 한국과 미국에서의 초임 과학 교사 전문성 발달에 영향을 미치는 주요 요인을 비교? 분석하는 것이다. 참여교사는 한국 수도권 지역과 미국 중서부지역에서의 초임 과학 중등교사 각각 네 명이다. 자료는 수업관찰 및 녹화, 반구조화된 면담을 통해 수집하였으며, 수업맥락을 이해하기 위한 수업관련 자료와 학생 활동 자료도 같이 수집하였다. 연구 결과는 다음과 같다. 첫째, 공통적으로 전문성 발달에 영향을 미치는 요인은 추구하는 교사상과 평가, 시험대비와 같은 학교 맥락이었다. 또한 한국 초임 교사들에게는 과학교과서와 행정적인 업무와 같은 맥락적인 요인이 전문성 발달에 영향을 미친 반면, 미국 초임교사들은 교생실습에서의 멘터 교사의 영향을 많이 받았다. 둘째, 참여교사들이 공통적으로 느낀 어려움이나 관심은 수업 관리와 교과 내용지식을 넓히는 것이었다. 셋째, 모든 참여교사들은 전문성 발달을 위해 많은 노력을 하고 있었으며, 추구하는 교사상이 현재와 미래의 교수실천에 중요한 역할을 하고 있었다. 넷째, 미국 참여교사들은 교생실습 때의 멘터 교사에 크게 영향을 받는 반면, 한국 참여교사들은 멘터 교사보다는 다른 여러 가지 요인들에 의해 영향을 받은 것으로 나타났다.

The data were collected from 171 physiologic malodor patients diagnosed in KUMC halitosis control clinic between 2008 and 2016. We selected 11 independent variables and 3 dependent variables, then planned to extract some convergent common factors affecting their physiologic malodor. We thought that those extracted convergent common factors could be utilized when preparing the contents of oral malodor preventive program. We used multiple regression analysis and path analysis method, for the analysis of influence of 11 independent factors to three salivary dependent factors(resting salivary flow rate, salivary buffering capacity, salivary precipitation rate). We have presented the physiologic malodor patients' chracteristics by descriptive statistical analysis, and also statistically analysed convergent common factors influencing directly or indirectly to their three dependent factors. We could reason that the sex, the character, the intake habit of breakfast, and the regular food intake habit could affect resting salivary flow rate, salivary buffering capacity and salivary precipitation rate.

본 연구에서는 원자력 선진국들의 원자력 미래기술의 예측 사례를 조사ㆍ분석하고, 이를 우리나라의 사례와 비교하였다. 조사된 미래 원자력 기술예측 및 수준 평가는 국외의 경우 일본, 독일 그리고 프랑스의 사례가 조사되었고 국내에서는 과학기술정책관리연구소와 한국원자력연구소의 사례를 원용하였다. 이들 사례에서 공통적으로 평가하고 있는 기술의 중요성, 실현시기 그리고 제약요인을 비교하였다. 기술평가 결과에 나타난 일반적인 특징은 우선 개별기술의 중요성 평가에서는 공통적으로 방사성패기물처리, 원전내진설계 그리고 원전해체기술 등과 같이 이미 활용중인 기술로서 기존 시설의 안전성을 향상시킬 수 있는 기술의 중요성을 높이 평가하고 있다. 다음으로 실현시기 평가에서는 레이저빔 이용기술과 같이 인접과학 분야의 발전에 따른 시너지 효과가 기대되는 분야의 기술이 2010년 이전에 실현될 것으로 평가하고 있다. 마지막으로 기술개발의 저해요인의 평가는 조사사례 별로 정도의 차이는 있으나 기술적 제약요인이 가장 높고, 다음으로 경제적 제약 그리고 사회적 제약의 순으로 평가하고 있다.

This study was conducted to identify the factors which influenced the learners' satisfaction in Cyber Home Learning System 2.0 and to propose the suggestions for design and implementation. 870 elementary school students and 153 middle school students were surveyed and factors which influenced learners' perceptions and satisfactions were analyzed. According to the results, four common factors on the perceptions about Cyber Home Learning System 2.0 were excluded according to the levels of schools. Based on the factor analysis results, multiple regression analysis was conducted to find out the influences on Cyber Home Learning System 2.0, for elementary school students, instruction specialty, usefulness of the contents, accessibility of system, and learning mood affected satisfactions significantly in the order. For middle school students, usefulness of the contents and the learning mood affected satisfactions significantly in the order.

Logistic discrimination is an useful statistical technique for quantitative analysis of financial service industry. Especially it is not only easy to be implemented, but also has good classification rate. Generalized additive model is useful for credit scoring since it has the same advantages of logistic discrimination as well as accounting ability for the nonlinear effects of the explanatory variables. It may, however, need too many additive terms in the model when the number of explanatory variables is very large and there may exist dependencies among the variables. Mixtures of factor analyzers can be used for dimension reduction of high-dimensional feature. This study proposes to use the low-dimensional factor scores of mixtures of factor analyzers as the new features in the generalized additive model. Its application is demonstrated in the classification of some real credit scoring data. The comparison of correct classification rates of competing techniques shows the superiority of the generalized additive model using factor scores.

This study is a study on the factors of preference for mobile game characters whose intellectual property rights (IP) influence is great. There have been many cases in which user-side research has been conducted on the character's preference factors. However, it is largely macro-divided. Detailed analytical studies are needed because details are overlooked. By classifying the elements of the character, the five-point scale of the recorder also obtains the data through the survey. Detailed factors were analyzed according to the results. Prior studies and results were compared and factors consistent with prior studies were analyzed. Because this study analyzed detailed factors, unlike previous studies of macro view. It is expected to help develop characters in the future.

The purpose of this study is to examine the characteristics or significances of anger in children by understanding the common factors observed in children's anger and the psychological process of children's anger, applying the experiential analysis method. In order to conduct the study, 8 elementary students in 5th grade participated in the experiential study as joint researchers. This study was conducted during 6 sessions. Joint researchers learned about the experiential analysis method and recorded what they had experienced at the stage of anger on their analysis sheets. 34 experiential analysis sheets were used for this study. The following provides a summary of the study results. Children were observed to perceive the factors representing desires more intensely than the factors indicating a mood or senses. Secondly, when they felt urge to express an extreme anger, they were just explored without the cognitive process of judgment. Thirdly, the processes that children feel and treat anger are "the stage of awareness of the situation," "the stage of initial cognitive evaluation," "the stage of induction of anger," "the stage of secondary cognitive evaluation or the stage of intensive drive of anger," and "the stage of anger management".

Keeping the semantic interoperability between different formats is very important for reuseing and consistently processing metadata. This article is to design common schema and KORMARC schema based on RDF schema. For this, common elements are made by comparison of Dublin Core elements and KORMARC fields. The schema of these elements is designed for construction of semantic interoperability, basing RDF schema specification and syntax specification. Eventually, the semantic interoperability between a number of metadata formats can be constructed by matching the common elements to each attribute of format. KORMARC schema is designed by the application of common schema.
