In this study, we examined the types and the characteristics of elementary school teachers' strategies for coping with critical incidents in science classes. Teachers' epistemological beliefs about science were then investigated on the bases of the types of their coping strategies. The teachers (N=107) in 23 elementary schools were asked to respond to an open-ended question about the critical incidents they had experienced in science classes and how to cope with them. Seven types of coping strategies were identified as follows: avoiding, reinterpretation, adjusting, prevaricating, justifying, exploring, and explaining. Among them, adjusting and justifying were the major strategies. In order to classify teachers' epistemological beliefs about science, their coping strategies were grouped into four categories such as transferring facts, constructing facts, transferring meanings, and constructing meanings. The results indicated that most teachers still possessed traditional epistemological beliefs about science. The potential of critical incidents as a probe for revealing teachers' epistemological beliefs about science is discussed.

The purpose of this study is to compare the key research-related constructs, research insterest, research self-efficacy, research productivity, and research outcome expectation of the graduate students, who are participating in Global Ph.D Fellowship (GPF) and Brain Korea (BK) 21 projects. The overall results show that the mean scores of GPF students in research interest, research self-efficacy, research productivity, and research outcome expectation are higher than those of BK21. However, the higher mean scores of doctoral students in both GPF and BK21 projects imply that the longer you stay in graduate program, the better researcher you can be. Although GPF program selected higher potential students and they seem to work very hard with high expectation to be competent researchers, compatible outcome also could be possible by BK21 project.

The current study reported on the continuing relevance of the schema theory for reading as it relates to the field of teaching and SLA, whilst highlighting the inherent limitations affecting individual learners. A relevant study was conducted for this article focusing on the extent to which university teacher trainees of English Education are exposed to second language readings with an adherence towards utilizing prior knowledge and drawing upon schemata to support their comprehension. Results from quantitative and qualitative data measured and collected from two groups of university students respectively, indicated certain advantages to this strategy use in respect of increased understanding, familiarity, and comfort level in SL reading. However, those same results identified existing limitations associated with cultural bias, stereotyping and a tendency to focus on wrong information when activating said schemata. As such, the purpose of this study is to promote awareness of the schema theory as an effective strategy option whilst reinforcing a need to pay heed to the concerns associated with strict reliance upon such theory to aid reading skills. Further discussion of these issues and pedagogical implications has been provided along with both suggested considerations regarding teaching for EFL teachers and evaluators.

There are many students around us, who are mathematically promising but have not taken some instructions with a program for the gifted. Providing a certain opportunity for them to take a differentiate program from one given normal students in a regular classroom has some limitations. If ever, offering a learning program developed with the connection of regular curriculum can lead them to reveal their potential. I think it is desirable that the effect of the program is more increasing when study in school keeps a reciprocal relationship to study in home for increasing the students' promising. In this paper, it is discussed to develop and implement the teaching learning program for the integration and connection of school and home for the Mathemaically Promising Students.

Homogeneous Charge Compression Ignition (HCCI) shows great potential for low $NO_x$ emission but is hampered by the problem of no direct method to control the combustion process. Therefore, HCCI combustion becomes unstable easily, especially at lower and higher engine load. This paper presents a method to achieve diesel-fueled HCCI combustion, which involves directly injecting diesel fuel into the cylinder before the piston arrives at top dead center in the exhaust stroke and adjusting the valve overlap duration to trap more high temperature residual gas in the cylinder. The combustion stability of diesel-fueled HCCI combustion and the effects of engine load, speed, and valve overlap on it are the main points of investigation. The results show that: diesel-fueled HCCI combustion has two-stage heat release rate (low temperature and high temperature heat release) and very low $NO_x$ emission, combustion stability of the HCCI engine is worse at lower load because of misfire and at higher load because of knock, the increase in engine speed aids combustion stability at lower load because the heat loss is reduced, and increasing negative valve overlap can increase in-cylinder temperature which aids combustion stability at lower load but harms it at higher load.

Currently, alternative medicine is highly utilized in the western countries. The public as well as health care practitioners have been paying a considerable attention to alternative medicine. This rapid growth in alternative medicine in many western countries suggests a high degree of public dissatisfaction with the limitations of orthodox medicine and concern over the side effects of chemical drugs. There is also a widespread recognition of the growing financial, social and personal cost for orthodox medicine. In addition, there is a growing need for a less fragmented, more participative and humane approach compared with contemporary medicine. Alternative medicine, which is based on holistic approach and lead to less expensive health care, may have the potential to playa significant role in overcoming the limitations of orthodox medicne in the western country. In this context, this study explores the recent trends of research on alternative medicine in western countries, particularly U.S.A. The study can provide us with valuable information on the types, training and education, utilization, insurance coverage, and regulation of alternative medicine in the western countries, thus offer important policy implications for the improvement of the korean health care system.

In the elementary school science curriculum, wind is one of the most important concept. In particular, land and sea breeze has been a key example to deliver how wind is driven, and thus its model experiments have been used to help students understand causes of wind. Here we compare causes and explanations for wind and land and sea breeze between textbooks in colleges and elementary schools to examine any potential improvement for the contents. In addition, we conducted survey to examine how pre-service teachers understand land and sea breeze, and convection box experiment used in elementary school textbooks is useful to understand land and sea breeze. Based on the comparison, we find that college level textbook explains the cause of wind as atmospheric pressure difference while elementary school textbooks explain them differently according to curriculums. In the textbooks, there are a difference in the way described for land and sea breeze. Analysis of questionnaire indicate that pre-service teachers understood land and sea breeze correctly, and they selected the convection box experiment in 2009 curriculum textbooks as the most suitable one. Explanations and experiments for land and sea breeze in the textbooks have been revised as the modification of elementary school curriculums. We expect this study helps to deliver more solid contents for wind and land and sea breeze in the upcoming new curriculum.

Background: In this study eugenol (EU) loaded nanoemulsions (NEs) emulsified with modified starch were prepared and their apoptotic potential against liver and colon cancer cells was examined in comparison with bulk EU. Materials and Methods: We prepared stable EU loaded NEs whcih were characterized by dynamic light scattering, centrifugation and gas chromatography. Furthermore, cell viability was determined using MTT assay, and apoptosis and cell cycle analysess by flow cytometry. Results: HB8065 (liver) and HTB37 (colon) cells when treated with EU:CA NEs demonstrated greater apoptotic cells percentages as evidenced by microscopic images and flow cytometric evaluations. It was observed that EU and EU:CA NE induced apoptosis in both cell lines via reactive oxygen species (ROS) generation. Conclusions: The present study demonstrated that ROS plays a critical role in EU and EU:CA NE induced apoptosis in HB8065 and HTB37 cells. This is the first report on the antiproliferative mechanisms of EU loaded NE.
