The purpose of this study is to show that epistemic considerations can be used meaningfully in the argumentation of elementary students, and to provide data on students' epistemic considerations that will be the basis for designing and evaluating scientific argumentation. The epistemic considerations in students' small group argumentations were explored based on Epistemic Considerations in Students' Epistemologies in Practice: EIP' suggested by Berland et al. (2016). The major results of this study are as follows: First, epistemic considerations in elementary school students' small group argumentation appeared in all four aspects: Nature, generality, justification and audience. The epistemic considerations varied according to context in each discussion situation. Second, epistemic considerations did not exist independently. They influenced each other and helped to reveal new types of considerations. The results of this study confirmed that argumentation can be used in elementary school science class. Understanding how students are involved in argumentation and how these epistemic considerations can affect students' argumentation can be helpful to teachers who design and evaluate small group argumentation. Students' achievement level affected epistemic considerations but learning approach types did not affect on. In addition, epistemic considerations may have a positive or negative effect on each other depending on the discussion situation in the process of interaction. So consideration of normative argumentation rules and teaching strategies should be considered in order for epistemic considerations to positively affect each other.

In this study, we explored students' epistemological framing during scientific argumentation and how interactions among group members influenced group argumentation. Twenty-one gifted science students divided into groups of three or four participated in this study. Students' discussions related to data interpretation concerning the rate of photosynthesis were analyzed. Students' activities were videotaped in groups so the discourse could be transcribed and students' behavioral cues analyzed. Students' epistemological framing has been identified through analysis of their speech and behavioral responses to the anomalous data from the inquiry process. Subsequently, their sources of warrant and group argumentation levels were explored. We found out that group members framed the inquiry in two ways: "understanding phenomena" and "classroom game." Group members whose framing was "understanding phenomena" required other members to justify the anomalous data by examining its validity and reliability, which conclusively demonstrated a high level of argumentation. On the other hand, when group members used "classroom game" to frame their argumentation, they did not recognize the necessity of explaining the anomalous data; rather, these students used simple empirical justification to explain the data, reflecting a low level of argumentation. When students using different epistemological framing disagreed over interpretations of anomalous data throughout the discussion, clashes ensued that resulted in emotional conflict and a lack of discussion. Students' framing shifts were observed during the discussion on which group leaders seemed to have a huge influence. This study lays the foundation for future work on establishing productive framing to prompt scientific argumentation in science classrooms.

The first demographic transition refers to the historical decline in mortality and fertility, as shown from the 18th Century in several European populations, and continuing present in most developing countries. The end point of the first demographic transition(FDT) was supposed to be a stationary and stable population corresponding with replacement fertility and zero population growth. In addition, households in all parts of the world would converge toward the nuclear and conjugal types, composed of married couples and their offspring. The second demographic transition(SDT), on the other hand, sees no such equilibrium as the end-point. Rather, new developments bring sub-replacement fertility, a multitude of living arrangements other than marriage, and the disconnection between marriage and procreation. Populations would face declining sizes if not complemented by new migrants. Over the last decades birth rates have been on the decline in all countries of the world, and it is estimated that already more than half of he world's population has below replacement level fertility. Measured in terms of the Total Fertility Rate (TFR), currently 34 countries have fertility levels of 1.5 or less. Similarly, Korea has been below lowest-low fertility for eight consecutive years since 2001 and below the replacement level for more than twenty years. In explaining the low fertility in Korea, some researchers explain the low fertility as revenge against a male-dominated society and institution, while others focus the impact of the employment instability. These studies share the basic ideas (spread of individualism, delayed marriage and childbearing, high divorce rate etc.) of a second demographic transition in order to explain the low fertility in Korea.

The purpose of this study was to examine the effects of Argument-based Inquiry activities on the claims and evidence in elementary students' science writing. Participants were thirty three fifth grade elementary school students and argument-based inquiry activities on five topics were implemented. We analyzed the Summary Writing samples written by students to investigate the effect of the Argument-based inquiry activities on elementary students' claims and evidence in their science writing, and also analyzed the writing samples of the experimental group to which the Argument-based inquiry activities were implemented, to examine the change of claims and evidence. The results of this study showed that the mean of experimental group was significantly higher than that of the comparison group. As a result of analyzing claims and evidence in Summary Writing of experimental group, the level of claim and evidence has tended to increase gradually as the number of classes progresses.

Because the local governments has closet contact for public services compared to central government, their role is important in the age when welfare issue is more important than before. So Local Public Finance being important than ever, but regrettably local financial issues related to the mostly negative. In particular, many local government face problem of local fiscal independence, as a result, they have hard time to secure financial resources. Reliant local finance by central government can be alternative, however, it causes negative effect for autonomous management of local finance and fiscal soundness. In this study, public data by public institutions is suggested as solution to secure financial resources. Although, utilization of public data is initial level, this paper deal with exploratory discussion for public data as self-reliant local finance with validity and suggestions.

최근 박막 태양전지의 시장 점유율이 전체 태양전지 시장에서 지속적으로 성장하고 있다. 이러한 박막 태양전지의 점유율은 주로 Fist Solar 사의 CdTe 박막 태양전지에 의해 이루어지고 있으며 Si 계 박막 태양전지와 CIGS 박막 태양전지 성장은 비교적 크지 않은 것이 현실이다. CdTe 박막 태양전지는 양산 효율이 약 10.5%에 달하고, 원가는 1$/W 이하 수준에 도달한 것으로 알려져 있으며, 향후 2011년 까지 양산 능력을 2 GW로 확대할 계획을 가지고 있다. Fist solar사는 Cd란 환경유해 물질을 메인 광흡수층에 포함하고 있다는 CdTe 박막 태양전지 제품적인 약점에도 불구하고 원가 절감, 투자비 최소화, 및 제품 성능 향상을 통해 태양전지 시장의 절대적인 강자로 떠오르고 있다. 이러한 성공의 배경에는 단순한 사업 전략적인 성공요인 외에도 제품의 기술적 경쟁력 확보가 무엇보다도 중요한 요소인 것으로 판단된다. Si 계 박막 태양전지의 경우 현재 AMAT 사 및 Oelikon 사와 같은 주요 turn-key 회사를 중심으로 생산량을 확대해가고 있으며, MHI 사, Kaneka 사, 및 Uni-Solar 사와 같은 Si 계 박막 태양전지 전문회사를 중심으로 제품의 효율 향상, 원가 절감, 및 투자비 감소를 위한 연구개발이 진행되고 있다. 본 발표에서는 이러한 박막 태양전지 전반적인 환경을 기반으로 향후 태양전지 시장 및 사업환경의 변화와 주요 박막 태양전지 기술 개발 방향 및 상업적 의미에 대해 논의하고자 하며, Si 계 박막 태양전지가 궁극적으로 세계 최고 수준의 제품이 되기 위해서 필요한 사업적 환경, 기술 개발 방향 및 주요 기술개발 이슈들에 대해 논의하고자 한다.

In this study, we explored the meaning of science education in an inclusive education setting tram the view of the epistemological approach, and discussed the principles and theories for constructing an educational program. Also, we explored the possibility of inclusive education in science education by suggesting principles for practice: accommodating science curriculum macroscopically, adapting science curriculum microscopically, considering diversity in science instruction, sharing the differences in science teaching and learning, and restructuring the assessment system in science education. We also reviewed the case on learning basic concepts in optics for the visually impaired according to the principles discussed. In conclusion, we discussed the considerations for the practice of inclusive education in science education and inferred further research problems.

The purpose of this paper is to classify and compare 21 OECD countries in regard to the level of support in parents' childcare and work. Several meaningful conclusions were suggested. First, examining the level of support in parents' childcare and work, 21 OECD countries can be classified into clusters different from the mainstream welfare state typology. Second, the level of parents' childcare and work support was high in socio-democratic countries such as Denmark, Finland, Norway and Sweden. Third, the level of parents' childcare right support is not necessarily positively related to that of parents' work in the labor market. As we have seen in the cases of France and Austria, although both countries have relatively high level of parents' childcare and work support, the level of work support in the labor market is low. These results have important implications for Korean family policy in that Korean society has to support both the parents' childcare right and the work right in the labor market.
