According to a number of recent studies, Korean students' affective achievement was at much lower level than cognitive achievement, which indicated the needs for nationwide researches. Although a variety of effort was put into finding ways to improve students' affective achievement, few researches focused on teachers was being underway. Thus, this study was conducted with 327 secondary school mathematics teachers in Gyeonggi-do- by survey method to investigate on how teachers feel affective domain in their teaching practice, how much they it into account at class, and what their wills or plans are to put it into action. According to the results, there existed a distinctive gap between teachers and students in affective domain.

In this study, in accordance with the research trend that the learner's emotions expressed positively or negatively in mathematics learning or the learner's beliefs and attitudes toward mathematics learning affect the results of mathematics learning, the learner's emotions and affective factors are analyzed in the learner's own learning. A power that can be adjusted according to a goal or purpose is needed, and I tried to explain this power through meta-affect. To this end, the meaning of the definitional and conceptual factors of meta-affect was explored based on prior studies. Affective factors of meta-affect were viewed as emotions, attitudes, and beliefs, and conceptual factors of meta-affect were viewed as awareness, evaluating, controlling, utilization, and monitoring, and the meaning of each conceptual factor was also defined. In this study, the conceptual factors and meanings of meta-affect in terms of using them to help in learning mathematics by controlling them, beyond the identification or examination of the characteristics of the affective factors, which are meaningfully dealt with in the field of mathematics education.

The purpose of this study is to find ways to establish and operate Process-focused Assessment in the classroom as the 2015 revised curriculum has emerged. As a way of doing so, we proposed a Process-focused Assessment through self-assessment and looked at the impact of the applied classes on the mathematical academic performance and affective domain of fifth-grade elementary school students. After selecting two classes of fifth grade with proven homogeneity for research, the experimental group applied Process-focused Assessment through self-assessment and the teacher-led Process-focused Assessment to the comparative group. As a result, it was confirmed that the classes applying Process-focused Assessment through self-assessment significantly improved the math and academic performance of fifth-grade elementary school students. The affective domain of the experimental group did not change significantly, but the analysis of the students' comments and interview data showed that they had more interest and confidence in mathematics.

This paper examines how Nietzsche, criticizing anti-naturalist philosophies, reformulated concepts of nature and human nature, and revaluated them from the perspective of naturalism. Especially, it focuses on his task for naturalistic ethics to naturalize nature and to place man back into nature. This paper also tries to reinterpret his attempt to transfer the concept of justice from the metaphysical realm to the naturalistic one, which seems to give some important insights to develop theory of environmental justice, while pointing out some limitations in his naturalistic concept of justice.

CMMI는 조직의 역량 성숙도를 향상시키기 위한 소프트웨어 프로세스 개선(SPI) 모델이다 CMMI의 단계적 형태(Staged Representation)의 2레벨을 획득하기 위해서 요구되는 요구사항 관리 프로세스 영역은 요구사항에 대한 협의 확정(Commitment) 활동을 포항하고 있다. 요구사항 관리 프로세스 영역은 이전에 협의 확정된 요구사항이 필요한 경우 변경이 가능하도록 허용하고 있는데, CMMI와 같이 프로세스 중심적인 모델에서 이러한 변경 가능성은 협의 확정 사항의 무한정 확대(Escalation of Commitment)와 같은 문제점을 야기할 수 있다. 본 논문에서는 SPI학계에서 사용되는 협의 확정에 대한 정의를 살펴보고, 이 정의를 CMMI에 적용함으로써 요구사항 관리 프로세스 영역의 협의 확정을 수행하는 활동에서 발생할 수 있는 문제점을 해결하기 위한 방안을 제시한다. 협의 확정의 개념은 Brown에 의해서 정의된 속성(1)과 Meyer에 의해서 제안된 형태(2)를 적용하여 정성적이고 정량적인 관리가 가능할 수 있다. 이를 통하여, 요구사항의 협의 확정에 대한 체계적인 관리가 가능해질 수 있다.

This study aims to develop strategies for improving the affective characteristics of Korean students based on results from international achievement tests. In pursuing the goal, different research methods are employed including a) analysis of the theories and literature regarding the affective domains included in PISA and TIMSS studies; b) analysis of the current situation and needs of Korean students with respect to the affective factors based on PISA and TIMSS results; c) case studies of best practices in relation to students' affective domains in Korea and abroad; and d) development of strategies for improving and supporting Korean students' affective characteristics. Especially, this paper describes meta-analyses of the results from the previous PISA and TIMSS studies. Afterwards, it reports statistical analyses results on the relationship between students' affective achievements and educational context variables. Data from TIMSS 2011, TIMSS 2007, PISA 2006, and PISA 2003 are used for the analyses, and contextual variables are selected through rigorous statistical analyses including frequency and correlation, and expert consultation. The effects of educational contextual variables on students' affective achievement in mathematics and science are analyzed through Hierarchical Linear Model.

모바일 기기의 사용자 만족도를 평가하기 위해 interface 부분만 아니라, 물리적 외형(design)에 대한 평가가 중요하게 되었다. 특히, 휴대폰의 물리적(physical) 부분을 평가하는 사용자의 감성적, 선호도를 중심으로 평가 되었다. Design 에 대한 Usability 측면을 고려하여, 감성적 선호도를 넘어서서 사용자의 사용 scene을 고려한 Physical User Experience 에 대한 영역정의가 필요로 한다. 또한 평가시 활용된 방법에 대해서도 정의가 필요하다. 따라서 이러한 특성에 의해, 모바일 기기의 4Physical User Experience를 평가하기 위한 사용자의 모바일 기기의 영역은 무엇이며, 평가 수행시 결과의 효용성을 높이기 위한 방법이 무엇인지 본 논문을 통해 정의하고자 한다.

The objective of the present study is to systematically examine the effects of on the cognitive and affective domains of elementary, middle, and high school students by conducting a meta-analysis. To this end, this study selected 31 research papers that had analyzed the effects of applying, and performed a meta-analysis of the findings presented in each research paper. The results obtained from the meta-analysis are presented as follows. First, both the collaborative learning program and the peer tutoring program for underachieving students in math manifested an above average size of effect in the cognitive domain. In particular, the effect was the greatest at the elementary school level, and out of the two programs, peer tutoring was identified to have a sizable effect. Second, both programs displayed an above average size of effect in the affective domain, and peer tutoring was identified to have a higher effect than collaborative learning. In addition, when the programs were compared based on school levels, the size of effect was highest at the elementary school level followed by middle school and high school, in that order. When compared based on the criteria of the affective domain, self-efficacy in math, learners' attitude toward math, and learners' interest in math were identified to. Finally, this study presented suggestions for teaching underachieving students in math and conducting follow-up studies based on the analysis results.

Intergenerational relations in Korea show very unique characteristics. In political arena, young and old generations clash each other intensely, while they maintain a high level of intergenerational solidarity in policy realm. A logistic regression analysis reveals that generational cleavage plays a key role in affecting voting decision and evaluation of governmental performance. It also suggests that in policy realm, normative, functional, and affectional types of solidarity influence people's attitudes on social policies very strongly. If the current government continues to neglect its promises for expanding welfare, the dual structure of generational cleavage in political arena and intergenerational solidarity in social policy realm can soon be turned into a conflictual structure. Therefore, an active initiative to increase intergenerational justice should be taken in order to attain a long-term, sustainable intergenerational solidarity and coexistence.

기존의 웨이브릿 기반 프랙탈 압축 방법은 전 영역에 대하여 최적의 정의역을 탐색하므로, 부호화 과정에서 많은 탐색시간이 소요되는 단점이 있다. 그래서 본 논문에서는 웨이브릿 변환영역에서 SAS(Self Affine System) 기법과 다중 스케일 인자를 이용한 웨이브릿 변환 기반 프랙탈 영상 압축 방법을 제안한다. 웨이브릿 기반 영역에서 정의역과 치역을 구성하고, 각각의 치역 블럭에 대해 모든 정의역 블럭을 탐색하는 것이 아니라, 정의역 탐색과정이 필요 없는 SAS 기법을 도입하여 공간적으로 같은 위치에 있는 상위 레벨 블록을 정의역으로 선택한다 그래서 부호화 과정에서 곱셈 계산량을 감소시켜 고속 부호화를 가능하게 한다. 그리고 SAS 기법의 단점인 화질이 떨어지는 단점을 개선하기 위해, 각 레벨별로 서로 다른 스케일 인자를 사 용하여 화질을 개선한다. 그 결과 화질에는 영향을 미치지 않고 부호화 시간과 압축률이 개선되고, 점진적 전송이 가능한 알고리듬을 제안한다.
