For STEM education science teachers usually choose topics which are related to both science and other disciplinary contents. Nevertheless it is not clear for the teachers to adopt what kind of criteria for their choices. Interdisciplinary teaching is not a mixture of science content with another one from different disciplines as resources for the content teaching. Instead the criteria and perspectives for the integration need to be clearly defined. In this study we investigated how to integrate science and other disciplines in terms of interdisciplinary teaching. Family resemblance approach by Wittgenstein, recently revised by Erduran and Dagher, was applied to comparative analysis of science, math, and physical education curriculum documents in Korea. Aim and value, methodological rules and methods, knowledge, and activities in each discipline were compared and analyzed with the view of FRA. Results of the study described alternative criteria of how to find appropriate topics for interdisciplinary teaching.

본 연구의 목적은 과학고등학교 학생들을 대상으로 '양자점 용액의 발광'을 주제로 하는 융합적 STEM(Science, Technology, Engineering and Mathematics) 프로젝트를 수행하게 했을 때 학생들이 어떤 창의성과 어떤 과학적 태도를 보이는지를 조사하는 것이었다. 이를 위해 STEM 프로젝트를 수행하고자 원하는 과학고등학교 2학년생 3명을 한 팀이 되도록 구성하였으며, 이들은 과학고등학교 수준 이상의 과학기술을 공부하기를 원하는 학생들이었다. 이들은 양자점 용액과 관련된 물리적 성질을 탐구하는 것으로부터 시작하여 점차 그들의 생각을 확장해 나가면서 공학, 기술, 수학을 통합해 나갔다. 그 과정에서 학생들은 과학적 문제해결력을 보였고, 아울러 협동심, 인내, 성취에 대한 만족감과 같은 과학적 태도를 나타냈다.

Recently, worldwide attention has been placed on being able to develop a person with interdisciplinary abilities. Specifically, there has been an emphasis on the integration of the previous STEM education and the arts, as well as the role of IT in technology and engineering education. Therefore, for this study, our goal is to help pave the way for the increased use of the teaching-learning methods of the IT-based STEAM education in developing people with interdisciplinary abilities. Firstly, we searched through domestic and foreign papers for example related to the recent trend towards the STEAM and integrative IT education models. In this study, we also presented a realistic teaching model based on STEAM education, applied mainly in the U.S., and on the teaching-learning methods of science and technology. The method we suggested is rated by expert assessments as a highly effective teaching-learning method for science and math. The use of educational IT technology in the STEAM education method is also analyzed with positive results.

Purpose: The purpose of this study was to explore the meaning and essence of good nursing from the perspective of patients undergoing hemodialysis. Methods: The data were collected through in-depth interviews of five hemodialysis patients who have been dialyzed for one year or longer. The data analysis was conducted using the Giorgi's phenomenological method. Results: The findings included six constituents and 13 sub-constituents. The six constituents were 'prompt and skillful response to mitigate distress', 'careful attention to provide relief', 'individualized education to promote self-management', 'an intimate relationship to regain isolated ego', 'warmhearted support to encourage strength to live in a exhausting life', and 'providing of comfortable environment to maintain stability'. Conclusion: From the perspective of the hemodialysis patients, the concept of good nursing should stem from the integration of nurses' scientific knowledge, expert skills, and moral sensitivity. The finding suggests that strategies to develop nursing interventions for hemodialysis patients will be required on the basis of understanding of their sociocultural contexts and familism.

Gene-manipulated mice were discovered for the first time about a quarter century ago. Since then, numerous sophisticated technologies have been developed and applied to answer key questions about the fundamental roles of the genes of interest. Functional genomics can be characterized into gain-of-function and loss-of-function, which are called transgenic and knock-out studies, respectively. To make transgenic mice, the most widely used technique is the microinjection of transgene-containing vectors into the embryonic pronucleus. However, there are critical drawbacks: namely position effects, integration of unknown copies of a foreign gene, and instability of the foreign DNA within the host genome. To overcome these problems, the ROSA26 locus was used for the knock-in site of a transgene. Usage of this locus is discussed for the gain of function study as well as for several brilliant approaches such as conditional/inducible transgenic system, reproducible/inducible knockdown system, specific cell ablation by Cre-mediated expression of DTA, Cre-ERTM mice as a useful tool for temporal gene regulation, MORE mice as a germ line delete and site specific recombinase system. Techniques to make null mutant mice include complicated steps: vector design and construction, colony selection of embryonic stem (ES) cells, production of chimera mice, confirmation of germ line transmission, and so forth. It is tedious and labor intensive work and difficult to approach. Thus, it is not readily accessible by most researchers. In order to overcome such limitations, technical breakthroughs such as reporter knock-in and gene knock-out system, production of homozygous mutant ES cells from a single targeting vector, and production of mutant mice from tetraploid embryos are developed. With these upcoming progresses, it is important to consider how we could develop these systems further and expand to other animal models such as pigs and monkeys that have more physiological similarities to humans.
