  • For the major scientific laboratories around the world, nanotechnology has been one of the key scientific issues since the end of the last millenium. The basic materials of this newly emerging technology are nanoparticles, which, in fact, have been used for many centuries. However, the physical properties of the particles were understood quite recently. In order to apply the new properties we have to protect and functionalize the surfaces of the particles, since without protection of the surfaces, nanoparticles grow themselves due to Ostwald Ripening. In this review, the author describes recent technical progress in the field of fuctionalization of various nanoparticles and their applications, so that readers can grasp the overall picture of this new technological field.

  • Authors observed 12 cases among the 46 corps which are died from 'charring', caused by traffic accident, for the purpose of individual identification. Concerning to the method of identification, authors took the dental hard tissue which is high in resitance to heat, using the method of Forensic Odontology and got a good results from it. In this inspection, we observed 'pugilistic posture' which results from heat coagulation & shrinkage of muscular bundle with predominance of the stronger flexor muscles. On the other hand, there appeared the fact that hair is more resistant to heat than skin or muscle.

  • The purpose of this study is to clarify that critical writing can be a positive stimulus factor for the cultivation of critical thinking through actual cases of writing education targeting engineering students in universities. Critical writing education is a very important way to develop critical thinking necessary for acquiring scientific knowledge, sharing social values, creativity and cultivating new production capacity. Especially, when critical writing education is performed with materials that maintain critical view of social reality such as the movie "Bowling for Columbine", it is characterized by the fact that it is naturally combined with the dimension of engineering ethics faced by engineers from the analysis and judgment of social reality. This is an example of the fact that critical thinking education for engineering students does not necessarily meet their major areas.

  • The theory of 4 great doctors in Geum Won era has been considered as a most scientific medicine after SangHanRon of Jang, Jung Kyung. And it influence for all the later medical theory and practice. I have found a common points between their Fire and Fever pathology and constitutional pathology of Li, Je Ma. The results obtained are as follows. 1. On the Viewpoint of medical history, there is common points in the fact that the start of Geum Won 4 great doctor' principle had been drived from awakening of the abuse of warm and hot herbs based on Hwa Je Guk Bang in the last stage of Song dynasty, and that the appearance of Sa Sang medicine was from the scientific reflection against the currency of the animation by warm herbs which was popular in the Jo Sun dynasty. 2. The theory of Fire and Fever pathology of 4 great doctors has been fixed in the principle of Cold and Fever pathology of viscera and bowel in the Sa Sang medicine. 3. The pathological meaning of 'internal fire' in the conculusion by 4 great doctors has got scientific fruit by Sa Sang medicine in its theory of four constitutional psychology and the formation of four visceras. 4. It is considered that the study of DongUiSuSeBoWon is needed for the relation with former medical theories.

  • Purpose: The purposes of this review were to address misconceptions of childhood fever and fever management practice among parents and health care providers, and to identify the scientific evidences against such misconceptions and practices. Methods: Journal databases and clinical guidelines from 2000 to 2015 were searched. The search terms were fever, fever management, misconception, myth, fiction, fact, fever phobia, child, antipyretics, tepid bath, alternating use/combined use of antipyretics, and physical cooling method. Results: There are significant gaps between current concepts and practices, and the scientific evidence. Misconceptions and unrealistic concerns about childhood fever still exist among parents and even health care providers, worldwide. The evidences suggest that antipyretics should be given carefully with the aim of relieving discomfort or pain rather than decreasing the temperature itself. Alternating use of antipyretics should be discouraged due to the risk of confusion and error. Antipyretics do not prevent febrile convulsions. Moreover, the scientific evidence does not support tepid sponge massage. Conclusion: Evidence-based childhood fever management interventions should be targeted toward parents and health care providers. By adopting an evidence-based approach to nursing interventions, pediatric nurses can ensure children receive appropriate and safe fever management.

  • Purpose: This article aims to explore the distribution of technological innovation and environmental policy challenges to respond to COVID-19. The study also attempts to tackle a paradigm shift in science and technology policies against the pandemic and a desirable direction for environmental policies. The COVID-19 pandemic has been the one that rapidly changed global people's lifestyle. For the spread of a terrible infectious disease could not be avoided, regardless of a highly industrialized society. Research design, data and methodology: This study basically employs a qualitative approach as a methodology. This study is based on the fact that environmental pollution, various natural disasters continuously occur, and there are many unforeseeable parts, despite remarkable development of scientific technology, and that the circumstances are becoming more complex. Results: This study noted that scientific technology civilization formed due to industrial revolutions can deteriorate environment and increase environmental threat factors. As an alternative to this, this study investigates alternative discussions on how the 4th Industrial Revolution can help scientific technology and human environment to harmoniously coexist and develop. Conclusions: It implies that this study focuses on the possibility of overcoming this crisis through science and technology innovation, although mankind is in crisis of COVID-19 due to excessive human development.

  • 본 연구에서는 과학기술정보시스템과 과학기술정보콘텐츠를 대상으로 인터넷 웹콘텐츠 접근성 지침 1.0을 기반으로 평가도구 K-WAH 3.0을 통해 웹접근성을 평가하였다. 과학기술정보시스템과 콘텐츠의 홈페이지의 웹접근성을 평가한 결과 콘텐츠보다 정보시스템의 웹접근성 준수율이 저조하게 나타났다. 이를 통해 웹접근성의 정보시스템과 콘텐츠의 특징과 차이점을 파악하고 향후 개선 방향을 제시하였다. 평가 결과 시스템 사이트가 콘텐츠사이트보다 우수한 것으로 나타났다. 그리고 NDSL을 제외한 과학기술시스템과 콘텐츠 사이트가 '이해의 용이성', '견고성' 준수율이 아주 저조하게 나타났다. 따라서 '이해하기 쉽게', '웹디자인에 화려한 장식을 자제'하는 웹페이지를 만드는 것이 요구된다.

  • 이 글에서는 '과학기술에 대한 시민의식 조사' 자료 분석을 통해 4대강 사업에 관한 시민의식의 변화, 특히 시민의 전문가 신뢰의 변화를 살펴봄으로써 '전문지식 정치'의 변화 양상을 이해해보고자 했다. 조사결과로 정부와 찬성 측 전문가의 신뢰도가 하락한 반면에, 반대 측 전문가, 환경단체의 신뢰도는 유지되거나 약간 상승하였다. 이것은 4대강 사업이 전문지식을 둘러싼 정치적 대결의 장이라는 사실을 보여준다. 정부의 4대강 사업 정책결정 과정은 그 타당성을 둘러싼 과학기술적 전문지식권력의 활용과 관련되어 있다는 점에서 전문지식 정치의 관점에서 살펴볼 수 있는 것이다. 한편 4대강 사업과 같이 전문가의 전문지식의 영향이 큰 과학기술적 생태적 쟁점과 관련하여, 시민들의 관심이 높고 또 이러한 사업이 일상생활에 영향을 미친다는 생각이 큰 것은 시민들의 권리의식이 높아진 결과라고 할 수 있다. 이와 함께 정책결정 과정에의 참여 필요성에 대한 생각이나 실제적인 참여 의향이 적지 않은 것은 과학기술 시민자격, 특히 '시민자격-책무 덕성'의 발달에 기인한다고 해석할 수 있다.

  • 한국 사회에서 도덕, 윤리 교육의 위기는 학문적 정체성을 명확히 확립하지 못한 데에서 출발한다. 일제시대에는 식민지 의식을 고취하기 위해 '수신'과목으로 출발하여, 미군정기 이후에는 '국민윤리'로서 개칭되면서 순수한 의미의 도덕교육과 일종의 반공교육과 정치 이데올로기 교육을 결합시켜 정체불명의 교과목을 만들어 정권 선전의 의도와 역할을 공공연히 담당하도록 만들었다. 그러나 윤리교육의 학적 근거는 윤리학이며, 윤리학은 철학의 분과 학문이다. 이러한 명확한 사실을 피하기 위해서 일부 학자들은 도덕, 윤리 교과의 학제적 성격은 말하지만, 이것이 오히려 기존의 도덕, 윤리 교과의 학적 근거를 다른 학문에 나눠주는 예상치 못한 결과를 초래하여 교육학에 교사 자격을 허용하게 만들고, 나아가 사회학에 교과가 통합될 위기에 처할 빌미를 제공해버리고 말았다. 윤리학의 모학문인 철학은 이미 고대로부터 학제적 성격이 아닌 통합학문의 이념을 가지고 있었으므로 다른 학문들에서 학적 근거를 찾을 필요가 없다. 이제 도덕, 윤리 교육은 다시 순수한 의미의 도덕, 윤리의 역할을 되찾을 필요가 있다. 과거의 체제수호적인 반공교육이나 사회과학적 정치 교육은 해당 과목에 귀속시키고 윤리교육의 본래적 목적을 구현하여 현행 도덕 교과서의 학습 목표에 따라 다양한 도덕 문제들을 "합리적으로 해결할 수 있는 판단능력"과 "삶의 이상과 원리를 체계화하여 실천할 수 있는 도덕적 성향을 길러" 주는데 역점을 두어야 할 것이다.

  • Recently, women astronomers have played increasingly important roles in the International Astronomical Union (IAU). Although only 18% are women across the entire membership of the IAU, currently one half of the IAU Executive Committee members are female. In fact, the previous, current, and next presidents of the IAU and many of the Division presidents are women. I will review a variety of efforts that the IAU has carried out to pursue equality and diversity in Astronomy. Also I will share my personal experience and thoughts on meritocracy as a guiding principle that governs academic integrity and scholarly power system in scientific communities in Korea.
