본 연구를 수행하게된 동기는 1994년부터 미국에서 S.A.T.를 개정하고, 한국에서는 대학 수학 능력 시험 제도라는 새로운 제도가 도입되는 것에 있다. 대학 학업 적성 평가 제도로서 미국의 S.A.T. 제도에 대한 유효성이 많은 학자들에 의해서 연구되고 있다. 대학 수학 능력 시험과 S.A.T.는 각각 한국과 미국의 대학에서 학업 적성을 측정한다는 면에서 그 목적이 같다. 한국의 대학 수학 능력 시험의 유효성을 연구하기에는 아직 실시되지 않았으므로 너무 이르다고 본다. 대학 수학 능력 시험 제도 확립이 실험 평가에 근거하기 때문에 대학 수학 능력 시험 실험 평가와 S.A.T.를 비교 연구하는 것은 의미가 있다고 본다. 따라서 본 논문에서는 한국의 대학 수학 능력 시험 실험 평가(수리)와 미국의 S.AT.(수학)와의 상관 관계를 연구한다. 본 연구의 조사 대상으로 선발된 집단으로서 광주시의 3개교 6학급의 고등학교 3학년 283명이 참가하였다. 본 논문에서 다음과 같은 문제가 연구되었다. 1. 7차 실험 평가(수리)와 S.A.T.(수학)의 평균 점수에 대한 남녀 차이의 통계학적 유의성 (statistical significance). 2. 7차 실험 평가(수리)와 S.A.T.(수학)의 평균 점수에 대한 자연계 인문계 차이의 통계학적 유의성 (statistical significance). 3. 한국의 대학 수학 능력 시험 실험 평가(수리)와 미국의 S.A.T.(수학)의 상관 관계.

Technology adoption has been an important issue for researchers and practitioners. In this paper, we identified the relationships between intention of technology adoption and technological affinity and other psychometric characteristics. We believe that technology affinity may be one of the general psychometric traits of individuals, and thus people have a different affinity levels which may influence the technology adoption intention. As a result it was found that need for cognition and self efficacy had positive influence on technology affinity, and the affinity also positively affected adoption intention. In addition, it was also found that technology affinity displayed a mediating role for the consumers adoption intention with need for cognition and self efficacy.

This paper presents comparison and analysis of various CFA patterns which are used in single sensor digital camera. There are several patterns which are already used, however, images are sometimes darker or brighter than what human see in real life. Also, images show some noise and blurring. To overcome this problems, many studies on the patterns have been discussed. We carry out experiment with seven patterns including the Bayer pattern. The bilinear method is selected for a interpolation method. The experimental result indicates that image quality is not affected by individual patterns and each pattern requires its own interpolation method.

Many of the analyses of the transient radionuclide migration are approximated by an one-dimensional geometry and/or planar geometry. To validate these approximations, one should prove that these are reasonable and proper approximations. In this paper, the approximation which was in the study of the transport through backfill into a fissure is tried to validate. In that analysis, a cylindrical geometry was approximated by a planar geometry. The numerical illustrations show that the planar approximation agrees very well with the result of the cylindrical geometry for a ratio of the backfill outer radius to the waste form radius closed to unity. Even for a larger ratio of the two radii, the numerical difference is relatively small. Also the planar approximation which was used in the analysis gives conservative estimates.

Confucius has been viewed as a conservative thinker. Quite a few scholars even argued that it was Confucius who laid the foundations stone of the conservative tradition of Chinese politics. No matter how one defines "conservatism," it seems clear that the relevant passages in the Analects support such interpretation. However, Lothar von Falkenhausen, an archeologist, recently argued that what Confucius upheld as venerable tradition was not a distant past but Confucius own times. This paper attempts to resolve the contradiction between the archeological evidence of Falkenhausen's claim and the textual evidence of the Analects through closer reading of the evidence.

World Health Organization reveals its plan for listing 'Gaming Disorder' on the 11th International Disease Codes (ICD-11) in 2018 and it opens hot debate among scholars on its validity and timeliness. Korea, however, seems to have avoided the issue without appropriate academic refutation. In this paper, we review past academic studies related to game addiction or disorder focused on their validity of disorder measurement tools, research designs and the effect of neuroimaging studies. This analysis reveals that excessive use of gaming is not sufficient to register it as a disease and there is a risk of stigmatizing healthy gamers.

The oxidation states of structural Fe in minerals reflect the paleo-depositional redox conditions for the biologically or abiotically induced mineral formation. Particularly, nano-scale analysis using high-resolution transmission electron microscopy (HRTEM) and electron energy loss spectroscopy (EELS) is necessary to identify evidence for the microbial role in the biomineralization. HRTEM-EELS analysis of oxidation states of structural Fe and carbon bonding structure differentiate biological factors in mineralization by mapping the distribution of Fe(II)/Fe(III) and source of organic C. HRTEM-EELS technique provides geomicrobiologists with the direct nano-scale evidence of microbe-mineral interaction.

As the gaming industry grows, the need to understand and study on game Addiction and overindulgence have also grown. For this object, in this study, the author first studied how game elements and game mechanisms were categorized by using previous studies. As a result, game elements are divided into three elements that compose visual, competitive, and probability elements. And the game mechanisms that establish three elements were grouped into subcategories. Risk of competitive and visual element that effect on overindulgence is depended on what mechanism has used. But, in the probability element, Gambling mechanism must be viewed in terms of addiction, not overindulgence.

Records management professionals and scholars have emphasized the necessity of managing data set in administrative information systems as records, but it has not been practiced in the actual field. Applying paper-based records management standards and guidelines to data set management proved to be a difficult task because of technology-dependent characteristics, vast scale, and various operating environments. Therefore, the data set requires a management system that can accommodate the inherent characteristics of records and can be practically applied. This study developed and presented data set management methods and procedures based on the analysis of data set in public administrative information systems operating in public institutions.

기후 변화의 수자원 영향 평가에서 전지구모형이 갖는 불확실성이나 이산화탄소 배출 등의 시나리오별 불확실성에 대해서는 많은 연구가 진행되어져 왔으나, 외부의 변화가 아닌 지구 시스템상의 내부 변화에 대한 자연적인 변동성에 대해서는 상대적으로 연구가 미흡한 상태이다. 대표적인 내적 변동성의 예시로 엘리뇨 또는 라니뇨 현상을 들 수 있으며, 일정 영역 해수의 온도 변화에 따른 순환정도가 전세계적으로 큰 영향 (태풍, 가뭄, 홍수 등)을 주는 것을 확인할 수 있었다. 유역에서의 침식 및 퇴적 현상에서도 기후변화에서와 비슷한 내적변동성의 영향이 관찰되어지나, 과거의 대부분의 연구는 외적변동성의 영향에만 집중되어 왔다. 가장 빈번하게 발생하는 예로, 토양 표면의 미묘한 변화 (aggregation, dispersion, shielding, crusting 등)때문에 같은 양의 강우 또는 유출이 발생하는 경우라도 같은 양의 침식량이 발생하지 않는 현상을 들 수 있다. 여기에서 다루어지는 침식량의 '다름'은 같은 지역에서라도 적게는 수십배에서 크게는 수백배까지 예측량이 다를 수 있음을 뜻한다. 이러한 다름이 그동안 수자원/지질학을 연구하는 학자 및 실무자로 하여금 수치모델을 적용하고 예측하는 것을 어렵게 했던 원인이 되었다. 본 연구에서는 기후 변화가 가져올 수자원의 영향 평가를 수행할 것이다. 관심있는 기후변화 변수로서 기온 및 강수량을 시간단위로 상세화할 것이며, 변화한 기후의 영향을 평가할 수자원의 현상으로는 증발산, 토양수분량, 유출량, 하천에서의 수심 및 첨두량, 침식량 등을 고려할 것이다. 물리현상을 모의하기 위해, 유역기반의 수리, 수문, 침식 및 퇴적 현상을 동시에 계산할 수 있는 통합모델을 개발하였고 적용하였다. 여기에서 얻은 결과로부터 내적 변동성이 수자원 현상에 미치는 불확실성을 확률통계적인 기법을 이용하여 정량화할 수 있을 것이다.
