There are complex interactions between personal and contextual features in teaching in a science museum. In order to analyze two teachers' holding classes in a science museum, the CHAT (cultural historical activity theory) was used as an analysis tool in a case study. The analyses of the results revealed that both teachers had difficulties teaching in a science museum due to the contradictions among the factors of subject, rules, community, and division of labor in the activity system. Although both teachers had trouble with similar contradictions, there appeared to be different sets of internalization and externalization of such conflicts depending on the difference in the teacher's perceptions and experiences about teaching in a science museum, the passion and the motivation of the teachers. These suggested that efforts should be preceded to foster the activity system providing both emotional and social supports to teachers in order to activate teaching in a science museum. Taking a teacher training course on teaching in a science museum was also found to fail to function as mediating artifacts. The course should provide not only the experience of executing proper teaching strategies for teaching in a science museum and the feedback on their teaching, but also the guidance on how to lead to optimal expansion of the factors in the activity system.
Breathlessness is a frequent and distressing symptom in terminal cancer patients. Refractory breathlessness is defined as a state that does not respond to conventional disease-specific therapy with an exclusion of reversible underlying causes, and the main classes of symptomatic drug treatments include opioids and benzodiazepines. Korean Family Medicine Palliative Medicine Research Group discussed two terminal cancer patients in whom severe breathlessness with different causes were treated with inhalation of nebulized furosemide, which is an emerging option of palliative treatment. It still remains unclear how it becomes effective or how much it is effective, therefore, its routine use seems to be somewhat early. Nevertherless, if a patient with intractable breathlessness does not have a marked obstructive airway lesion, its use should be considered. Based on the discussion in the seminar, we want to share our experience of the application of inhaled furosemide with other palliative care practitioners and strongly recommend further research on this topic in the future.
The purpose of this study was to develop teaching modules related to Earth Science courses in order to enhance scientific inquiry skills of middle school students. A 'process skill-centered' module was developed to induce scientific process skills, while students explore specific scientific context. A module consists of several activities, and each activity focuses on a specific science process skill. Modules were designed such that the skills would improve depending on the completion of the module. To evaluate the effectiveness, field workshops for middle school science teachers were done twice. Science teachers, who were participants of the workshop, commented that the activities in each module were suited to enhance students' interest in science. They noted that scientific inquiry skills would be developed from each activity. Students responded that the activities in the modules were interesting, and it was a good experience to do them by themselves. Students were the focal point in class, not teachers. This enabled teachers to evaluated each student's achievement level, and provide a proper feedback. Hence, applying these modules in classes should enhance the students' scientific inquiry skills.

This study was conducted on 2016 $1^{st}$ and $2^{nd}$ grade middle school students in order to investigate of their perceptions and needs on sewing practice class, which had been experienced during their $6^{th}$ grade elementary school year. Implications and improvement for sewing practice class to be drawn from this study. The findings are as follows: Firstly, the levels of satisfaction with the practice contents and teaching learning method were higher than the median value(3.00). Among the subareas of class evaluation, participation scored the highest average, followed by interest, difficulty, necessity, importance, and utilization. In the entire subareas, girl students have more positive perceptions on sewing practice classes than boy students. Secondly, satisfaction with the practice contents has an effect on all subareas of class evaluation. The satisfaction with the teaching learning method has an effect on participation, interest, importance and utilization. Lastly, as for the practice contents, they would prefer household items and ornament, and want to choose sizes freely. As for students' needs for a new teaching learning method through which students are allowed to freely make objects or create works through a group activity, it was higher than the median value. This study showed that practice contents and teaching learning method are important factors that affect class evaluation. This study suggested that sewing practice class should be conducted freely choosing of practice contents, making the group works, group or student-led activities. If sewing practice class is designed in consideration of the results and students' needs for class, students' perceptions on class is expected to change in a positive way.
While use of a pet bottle with use it is light recently and convenient increases quickly, it is used from the child, also diffusing the user to a pet bottle to people of various classes, such as an old person, a woman, a male, the man in the street, and a disabled person. However, those who are standardized on the basis of the common man with the plan energy of a pet bottle, and cannot attain to the standard, That is, a child and a disabled person may be condemnedto the vague situation that a lid cannot be opened or a contents thing cannot be drunk without external help. And the characteristic of a material and production which are called PET Even if convenience is emphasized for the cost reduction of COST, a design is chosen easily, and even if it calls it the man in the street, the point of coming to experience a situation with the difficult time of use can be found well. In research of a book, problem derivation which classifies entering school and a preschool boy and girl child for a child drink for an object first by the viewpoint of universal design paying attention to such problems, and leads the actual use example of a pet bottle was carried out in true heart, and various notional approach was shown by the solution method.
Unlike ordinary situations, deifinitions play a very important role in mathematics education in schools. Mathematical concepts have been mainly acquired by given definitions. However, according to didactical intentions, mathematics education in schools has employed mathematical concepts and definitions with less strict forms than those in pure mathematics. This research mainly discusses definitions used in geometry (promising) course in primary schools to cope with possibilities of creating misconception due to this didactical transformation. After analyzing problems with potential misconceptions, a survey was conducted $\underline{with}$ 80 primary school teachers in Jeju to investigate their recognitions in meaning of mathematical concepts in geometry and attitudes toward teaching. Most of the respondents answered they taught their students while they knew well about mathematical definitions in geometry but the respondents sometimes confused mathematical concepts of polygons and circles. Also, they were aware of problems in current mathematics textbooks which have explained figures in small topics (classes). Here, several suggestions are proposed as follows from analyzing teachers' recognitions and researches in mathematical viewpoints of definitions (promising) in geometric figures which have been adopted by current mathematics textbooks in primary schools from the seventh educational curriculum. First, when primary school students in their detailed operational stage studying figures, they tend to experience $\underline{a}$ collision between concept images acquired from activities to find out promising and concept images formed through promising. Therefore, a teaching method is required to lessen possibility of misconceptions. That is, there should be a communication method between defining conceptual definitions and Images. Second, we need to consider how geometric figures and their elements in primary school textbooks are connected with fundamental terminologies laying the foundation for geometrical definitions and more logical approaches should be adopted. Third, the consistency with studying geometric figures should be considered. Fourth, sorting activities about problems in coined words related to figures and way and time of their introductions should be emphasized. In primary schools mathematics curriculum, geometry has played a crucial role in increasing mathematical ways of thoughts. Hence, being introduced by parts from viewpoints of relational understanding should be emphasized more in textbooks and teachers should teach students after restructuring this. Mathematics teachers should help their students not only learn conceptual definitions of geometric figures in their courses well but also advance to rigid mathematical definitions. Therefore, that's why mathematics teachers should know meanings of concepts clearly and accurately.
This study presents how the engineering ethics instructional modules have been developed based on Korean culture and how they are implemented into the existing engineering curricula at Sungkyunkwan University. The engineering ethics instructional modules were designed to be taught by engineering faculty members who did not have any teaching experience in ethics. As a result, it was determined that the engineering ethics instructional modules should include a detailed instructor lesson plan and all supporting resources such as slides (Power Point base), and handouts, or assessment units (pre- and post-test). Two 75 minute modules developed in this study consist of the diverse instructional activities for various student group sizes. In order to improve students' interests and classroom attention, various visual and audio resources such as famous movies, cartoons, and poems were included in the instructional resources. In addition, a number of case studies which might happen in the students' daily lives were chosen. The resulting ethical module No. 1 has been instructed in the existing engineering classes during the 1st semester in 2007. Overall, the students reported positive impressions of the modules and the faculty members also reported favorable perceptions of the modules. Also, team based activities encouraged students to participate in constructing the event trees, which are a basic analysis tool for ethics case studies. The results of this study will provide a guideline of implementing engineering ethics into the engineering curricula to other engineering programs and schools.
In this study, using a questionnaire about camp programs, we surveyed 375 gifted education institutes, including 285 classes for the gifted, 70 institutes for the gifted at education offices, and 20 institutes for the gifted at universities. The survey questionnaire consists of questions relating to camp design, camp operation, and camp introspection. The questions relating to camp operation are subdivided into questions relating to content, process, product, and learning environment of the camp. In the analysis of camp design, experience-centered camps entailing visits to research institutes, science museums, and so on showed the highest ratio. The camps were generally carried out in summer vacation as two day/one night programs. The average score of camp content was 3.72, that of camp process was 3.78, that of camp product was 3.77, and that of camp environment was 3.58. In the analysis of camp introspection, the item 'a lack of information about diverse camp activities' showed the highest difficult thing. Integrating these results, we suggest that information about diverse camp activities should be developed and supplied and the camp environment strengthen the freedom of students to select camp activities.

Cells sense, respond, and adapt to a low oxygen environment called hypoxia, which is widely involved in a variety of human diseases. Adaptation to low oxygen concentrations includes gene expression changes by inducing hypoxic genes and reducing aerobic genes. Recently, the mitochondrial respiratory chain has been implicated in the control of these oxygen-regulated genes when cells experience hypoxia. In order to obtain an insight into an effect of the mitochondrial respiratory chain on cellular response to hyxpoxia, we here examined whole genome transcript signatures of respiration-proficient and respiration-deficient budding yeasts exposed to hypoxia using DNA microarrays. By comparing whole transcriptomes to hypoxia in respiration-proficient and respiration-deficient yeasts, we found that there are several classes of oxygen-regulated genes. Some of them require the mitochondrial respiratory chain for their expression under hypoxia while others do not. We found that the majority of hypoxic genes and aerobic genes need the mitochondrial respiratory chain for their expression under hypoxia. However, we also found that there are some hypoxic and aerobic genes whose expression under hypoxia is independent of the mitochondrial respiratory chain. These results indicate a key involvement of the mitochondrial respiratory chain in oxygen-regulated gene expression and multiple mechanisms for controlling oxygen-regulated gene expression. In addition, we provided gene ontology analyses and computational promoter analyses for hypoxic genes identified in the study. Together with differentially regulated genes under hypoxia, these post-analysis data will be useful resources for understanding the biology of response to hypoxia.
The purpose of this study was to examine the effect of GI-STEAM program on leadership, creative personality, and learning flow of elementary Gifted Students. GI-STEAM program was the convergence model of Group Investigation that belongs to Co-learning and STEAM framework of learning criterion. The participants were 16 gifted students in a Korean elementary school located in Gyeong-gi province. The experimental design was one group pretest-posttest design. After a pretest on leadership, creative personality, and learning flow was conducted, classes were carried out as GI-STEAM program for the gifted student and a post-test was conducted. The study results of the class that was conducted twelve times for two weeks are as follows. First, Individual area of leadership is meaningfully developed in statistics after GI-STEAM program. The sub-domains of leadership, such as the communication, organization management, society commitment and teamwork showed a statistically significant improvement. Second, the domain of creative personality didn't show meaningful difference after GI-STEAM program. However, the aesthetic in the sub-domains of the creative personality showed a statistically significant improvement. Third, learning flow was meaningfully developed in statistics after GI-STEAM program. The sub-domains of the leadership, such as the balance between challenge and ability, integration with behavior and consciousness, concrete feedback and Autotelic experience showed a statistically significant improvement. In conclusion, GI-STEAM is an effective program for improving ability of communication, aesthetic sensibility, which are core competency of 'creative-convergence' gifted students. For this reason, it is highly considered that various programs applying GI-STEAM should be developed.
