  • Community nutritionists draw upon theories from the social sciences to improve their work in health promotion and disease prevention. Social science theories are sets of concepts that provide systematic explanations that can predict events or situations, and are classified into several paradigms and worldviews. these theories interact with research and practice around the subject matter of community nutrition. Use of these theories provides benefits in community nutrition by helping to organize thinking about nutrition topics in ways that are useful for assessing , understanding, intervening, and evaluation community nutrition issues. Community nutrition researchers and practitioners can be choose from many available social science theories by evaluating assumptions, scope, applicability, complexity, effectiveness, and other aspects of the theories. Awareness and use of social science theories should enhance the development of community nutrition. (Korean J Community Nutrition2(5) : 671-679, 1997)

  • 학생들은 수업전 그들의 일상적인 경험, 직접적인 관찰, 문화적인 배경으로 인하여 자연 현상에 관하여 과학자가 지니는 과학적 사고(Scientific theories)와는 다른 유년적 사고(Naive theories)을 지니고 있다는 사실이 연구에 의하여 보고되어 왔다. 본 연구는 중력현상에 관한 학생들의 유년적 사고(Naive theories)를 조사한 것이다. 이의 대상은 국민학생 49명, 중학생 53명, 고동학교 49명으로 하였다. 연구 방법으로는 질문지법(Open-ended written questions)과 면접법(Interview)을 이용하였다. 연구 결과는 국민학생에서 고등학생에 이르기까지 중력현상에 관하여 유년적 사고(Naive theories)를 지니고 있는 것으로 밝혀졌다. 중력현상에 관한 유년적 사고(Naive theories)들은 중력 현상이 공기의 유무, 대기압, 마개의 유무, 물의 상태변화, 온도의 영향등으로 지배를 받는다고 설명하였으며, 이러한 생각은 고학년으로 갈수록 줄어들고 있음을 볼 수 있다. 질문지법(Open-ended written question)과 면접법(Interview)의 결과가 매우 일치하는 것으로 밝혀졌다.

  • Three failure theories were studied to evaluate the wood strength variation with grain slope. Maximum stress theory, Tsai-Hill theory and Hankinson formula were presented to hypothesize the failure of wood according to grain slope to loading direction. Red pine and Japanese larch were used as materials to simulate failure strength prediction with grain slope. Calculation of strength results was that the strength of wood drops rapidly between parallel to grain orientation (0 degree) and 15 degree grain orientation. The strength of wood with grain orientation were somewhat different at small grain angles among failure theories, and this tendency was due to tension and compression distinction, and shear accounting in each theories. For the above 45 degree grain orientation, the predicted failure strength of wood with grain variation were very close in each failure theories and were useful in assessing failure strength of wood. The applicable these theories should be considered that the wood has different behavior in tension and compression, and this lead to different strength at small grain angles in each theories. Furthermore, reconsideration is needed to assess the failure strength of wood at small grain angles in Hankinson formula and further studies are necessary to accounting for shear behavior at small grain angles.

  • Purpose: This research presents a practical tool aimed at increasing collaboration between designers and marketers for effective retail space branding. We present a design-related information processing model (DIP Model), which is a schematic map that includes cognitive theories which have design applications to retail space branding. Research design, data and methodology: Through literature review and practitioner opinion survey, 43 theories pertaining to the brand communication in retail spaces were selected, and design applications of the theories were analysed through field trips to stores of global brands. Results: The DIP Model consists of two axes: the information processing axis (i.e., encoding vsretrieval) and the regulatory focus axis(i.e., promotion vs prevention). Theories related to information processing axis are theories that facilitate the encoding and retrieval of information as intended by the company. Theories related to regulatory focus axis are theories that reinforce positive cognition and prevent negative cognition regarding the brand. Conclusions: The DIP Model is developed as a tool to categorise cognitive theories that are applicable to the design of brand communication in retail spaces. As such, the model can provide a better understanding of the role of behavioural design, with the aim of building stronger brands in retail spaces.

  • With accumulated nursing research results from older adults, refined middle range nursing theories are evolving in gerontological nursing area. Three middle range nursing theories and framework were reviewed and described. Life transition framework for older adults were developed through research related to relocation and other transitions taken place in later life. Self-efficacy exercise model was developed by extensive research related to rehabilitation of older adults based on self efficacy expectations and outcome expectations concept from social cognition theory. Need-Driven dementia-compromised Behavior (NDB) model was developed by a group of nursing scholars studying dysfunctional behaviors of demented older adults. All of these theories are approaching to practice theory by developing interventions and nursing therapeutics. There are more needs to develop theories for specific gerontological nursing phenomena such as delirium, end of life and self integrity.

  • 교육은 인간 행동의 계획적인 변화이다. 이러한 변화는 인간의 학습 과정을 통해 이루어진다. 학습이 이루어지는 과정과 그 심리적 기제를 설명하는 법칙이나 이론적 체계는 학습이론에 그 바탕을 두고 있다. 학교교육을 지원하는 기본 시설로서의 학교도서관은 교수-학습이론과 어떤 관련이 있고, 어떤 기여를 할 수 있는지, 그 방법은 어떻게 되어야 할 것인지에 대한 객관적 통찰은 학교도서관의 교육적 탐구와 학문적 탐구를 위한 기반이 된다. 본고에서는 학습이론의 큰 흐름인 행동주의 학습이론 인지주의 한습이론, 구성주의 학습이론 등을 중심으로 학교도서관의 교수-학습 이론적 기반을 고찰한다. 이를 바탕으로 학교도서관의 교육적 기초를 도서관기반교육접근법 (LBEA)으로 정립하고 있다.

  • In a essay that was published on 'Science' in December 2014 as a part of the supplement "The Art and Science of Traditional Medicine," the eastern and western medical theories are discussed with reference to the model-dependent realism suggested by Stephen Hawking and Leonard Mlodinow. This paper examines what the model-dependent realism is, and how it affects the future direction of researches in traditional Korean medical theories. The model-dependent realism holds a meaning in that it puts traditional medical theories in a perspective of models, and allows for application of recent studies in scientific philosophy for researches in traditional medical theories. Especially, the model studies by R. Giere et al. will help elaborate the traditional medical theories from a model perspective. From a model perspective, the 'visceral manifestation', 'meridian and collateral', 'qi-blood', 'eight principles' and 'constitution' theories of traditional medicine have the potentials to develop into valid models, and the traditional medical theory's phenomenological and holistic perspective distinguishes it from western medicine, giving it a competitive edge. In addition, the epistemological pluralism of model-dependent realism can serve as an alternative to relativism or rationalism perspective which put eastern and western medicine in opposition until now.

  • 본 연구의 목적은 학생들이 과학 이론과 과학 법칙의 차이를 어떻게 이해하고 있는가를 알아보는 것이다. 과학 지식의 서로 다른 종류인 과학 이론과 과학 법칙에 대해서 올바르게 이해하고 있는 것은 과학의 본성을 이해하는 데 있어서 매우 중요함에도 불구하고 이에 대한 연구는 충분히 이루어지지 않고 있기 때문이다. 본 연구에서는 서울 지역의 고등학교 학생 32명을 대상으로 개방형 질문으로 구성된 설문을 실시하였다. 조사 결과, 학생들은 '과학 이론은 아직 증명되지 않은 것이며, 과학 법칙은 확실히 증명된 것이다.' 및 '과학 이론이 충분한 증거가 뒷받침되어 증명되면 법칙이 된다.'는 오개념을 가지고 있는 것으로 나타났다. 아울러 학생들이 알고 있는 과학 이론의 상당수가 지구과학 과목에 포함되고, 알고 있는 과학 법칙의 대부분이 물리, 화학 과목에 포함되어 있는 것으로 미루어, 지구과학을 덜 과학적인 학문으로 잘못 인식하고 있을 가능성도 보였다. 따라서 과학 이론과 과학 법칙에 대한 분명한 차이를 이해하는 것은 지구과학에 대한 올바른 인식에도 도움을 줄 것으로 기대된다.

  • This paper proposes an approach in Southeast Asian studies using a post-colonial framework in the study of post-colonial Southeast Asia. This framework is based on the sociology of knowledge that analyzes the dialectical relationship between science, ideology, and discourse. Post-colonial studies is critical of the concept of universality in science and posits that a scientific statement of a society cannot stand alone, but is made by authors themselves who produce, use, and claim the so-called scientific statement. Several concepts in post-colonial theories can be used to develop area studies, i.e. colonial discourse, subaltern, mimicry, and hybridity. Therefore, this study also explores these concepts to develop a more comprehensive understanding of Southeast Asian culture. The development of post-colonial theories can be used to respond to the hegemony of social theories from Europe and the United States. The main contribution of area studies in the field of the social sciences and humanities is in revealing the hidden interests behind the universal social sciences.
