우리나라 교육 승인통계는 1963년 이래로 초·중등교육, 사교육, 고등교육, 평생교육 등을 포괄하며, 학생, 교원, 학부모, 관련 직원들의 실태조사, 의식조사 등을 망라하며 발전해오고 있다. 본 연구의 주된 목적은 UIS 교육통계를 중심으로 우리 교육 승인통계를 평가하고, 교육정책 수립을 위한 앞으로의 교육 통계조사의 발전방향을 논하는 것이었다. 본 연구에서는 먼저 교육 승인통계의 시기별 변천사를 알아보고, 총 73종의 교육 승인통계 중 59건을 기본통계, 초중등교육, 사교육, 고등교육, 평생교육의 다섯 가지 범주로 분류하였다. 다음으로 유네스코의 UIS 교육통계의 범주화, 분류체계, 방법론적 특징 등을 고찰하였다. UIS 교육통계에 비추어 볼 때, 우리나라 교육 승인통계는 상대적으로 유아교육이 간과되는 반면 사교육이 확고한 위치를 차지하고 있다는 특징이 있으며, 각 통계에 대한 방법론을 상세하게 문서화하여 제시할 필요가 있다. 본 연구는 총 73건의 우리나라 교육 승인통계를 평가하는 최초의 연구로, UIS 교육통계와의 비교를 통하여 우리나라 교육 승인통계의 향후 과제를 논하였다. Since 1963, Korea approved statistics of education have been conducting facts and/or perceptions surveys to students, teachers, and administrators, among others, in all possible educational institutions. The main purposes of this study were to evaluate the Korea approved statistics of education and to provide suggestions for future planning and practices of Korea approved statistics of education. Korea approved statistics of education were grouped in categories, and compared with the UIS(UNESCO Institute for Statistics) statistics, in terms of data collection methods, statistics categorization, and methodological characteristics. A total of 73 Korea approved statistics of education were examined, and 59 of them were categorized as the five groups: Basic, Elementary and Secondary, Private Tutoring, Higher Education, and Lifelong Education. Statistics on early childhood education are lacking, and the Private Tutoring category stands out, compared with UIS statistics. Documentation efforts on detailed methodology need to be furthered. This study is the first one on the 73 Korea approved statistics of education, and discussed suggestions to improve the Korea approved statistics of education.

명확한 기존 이론이 없어도 축적된 데이터 분석을 통하여 결과를 도출할 수 있는 데이터 마이닝 기법이 빅데이터 시대에 각광을 받고 있다. 수렴 또는 과적합 등의 문제로 인해 소수의 변수만을 모형화해 온 기존 연구방법과 달리, 데이터 마이닝 기법으로는 수백 개의 변수를 한 모형에 투입할 수 있으며, 따라서 연구방법적 측면에서 여러 장점을 가진다. 국가기관에서 십수년 간 수집해 온 교육 패널자료는 양적 · 질적인 측면에서 데이터 마이닝기법 적용에 적절하다. 본 연구는 빅데이터 분석에서 자주 이용되는 벌점회귀모형인 LASSO를 KYPS 5차 자료분석에 이용함으로써 데이터 마이닝 기법의 교육 패널자료 적용 사례를 제시하였다. 수십 개의 변수만을 이용하였던 기존 연구와 달리, 본 연구는 총 315개의 설명변수를 한 모형에 투입하여 15개의 변수를 선택하였다. 기존 연구에서 모형화된 변수뿐만 아니라 새로운 변수를 발굴할 수 있었다. 본 연구의 함의 및 후속 연구 주제 또한 논의되었다. With the advent of so-called big data era, data mining techniques have come to the fore as big data analysis tools. Unlike conventional statistical methods, data mining techniques can handle hundreds of variables in one model without convergence or overfitting problems. However, studies in the field of education have not yet paid enough attention to recent data mining techniques. Particularly, panel data with its hundreds of variables and thousands of participants can fit data mining techniques. This study aimed to illustrate a popular data mining technique, LASSO, by applying it to the 5th wave of KYPS (Korea Youth Panel Study). A penalized LASSO regression was executed with 10-fold cross-validation via deviance, and was successfully applied to the social sciences panel data. Implications of the study are discussed as well as further research topics.

유진,강필중 중앙대학교 스포츠과학연구소 2002 體育硏究 Vol.- No.16
The moderners are participating to a various sports activity for leisure and health. but some peoples received an impression with body injury and danger of life during participating to an adventure or extreme sports. Why this people to participate to an adventure or extreme sports? According to scholars, that reason is optimal arousal and the optimal experience theory. The representative scholar is Zukerman who developed Sensation Seeking Scale and written much of research about sensation seeking. When you knows research of the scholars against a sensation seeking, and knows the occurrence and a method of extreme sports, it becomes the many help to research of the young people's an adventurous character and leisure.

The main purpose of this study is to verify the structural validity of the questionnaire for the exercise motivation. Exploratory factor is for the member of sports clubs. In all 353 persons between 20-65ages, 154mans, 199 women. Average of the age is 37 (SD=12.1)ages. The exercise motivations inventory(EMI-Ⅱ), for the validation of factor structure we used the analysis of questions, of technica(frequency, average, standard deviation, skewness, kurtosis, etc.). The result of basic statistics verification is normal. With primary factors analysis for 14 factors of questionnaire, we can select 6 factors 21 questions including weight management, enjoyment, appearance, affiliation, strength & endurance, health pressures. The result of eigenvalue is 2.94-2.10, total variance is 72.4%. The correlation of exercise motivation factors is .65-.26. The Cronbach'a of each factor is .87-.75. With confirmatory factor analysis is GFI=.87, CFI=.91, TLI=.89, RMSER=.08. The factors correlation is .29-.83, .34-72 the variance of measurement error as .34-.72 express variance estimates sub-scale. In conclusion, The Exercise motivation inventory 2 of 6 factors 21 items of validation is reasonable with approval level. For the next study is will be the necessity of Indigenous psychological pure study with this result.

A Study on Photoreceptor by Using the Effect of Additives
유진,김영순,유국현,Yu, Jin,Kim, Yeong Sun,Yu, Guk Hyeon Korean Chemical Society 2001 Bulletin of the Korean Chemical Society Vol.22 No.7
We have been studied photosensitization mechanism's additive effect, of perylene 3,4,9,10-tetracarboxyl-diimide and X-phthalocyanine (charge generation materials), using the photochemical and photoelectrochemical approach. It was found that the photoreceptor on the excited state reacts with metal oxide, which creates the charge transfer on the interface of SnO2/electrolyte. In the electrode (X5P1) made of five X-phthalocyanine and single perylene 3,4,9,10-tetracarboxyldiimide layers, the cathodic photocurrent of X-phthalocyanine in the 400-600 nm region was increased by the addition of perylene 3,4,9,10-tetracarboxyldiimide. The maximum wavelength of fluorescence of perylene 3,4,9,10-tetracarboxyldiimide showed no dependence on the temperature. The addition of 4-dibenzylamino-2-methylbenzaldehyde diphenylhydrazone known as charge transport material was represented as decreasing photocurrent for X-phthalocyanine and perylene 3,4,9,10-tetracarboxyldiimide, respectively. In the electrode (X1P1) made of single X-phthalocyanine and single perylene 3,4,9,10-tetracarboxyldiimide layers, an anodic photocurrent of about 10.5 nA was generated by addition of hydroquinone at 550 nm. And the characteristic of photoinduced discharge was shown to decrease by a factor of 5 and the speed of dark decay was increased by a factor of 1.2.
