  • 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)

  • 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.

  • Education is an intentional change of human behaviors. This change is implemented through the learning process of humans. The principles in the learning process and its psychological mechanism are based on learning theories. The objective insight about how they are related with school libraries as a basic organization supporting school education, what they can contribute and what their research methodologies are is a base for educational and academic research of school libraries. This study at first is to investigate learning and teaching theories for school libraries based on behavioral learning theories, cognitive learning theories and constructive learning theories which are general trends for learning theories. Then it is to introduce new theory 'library-based education approach (LBEA)'as an educational base of school libraries.

  • 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.

A Preliminary Study on High School Students' Understanding of the Distinction between Scientific Theories and Scientific Laws (과학 이론과 과학 법칙의 차이에 대한 고등학생들의 인식 연구)

  • The purpose of this study is to explore high school students' understanding of the distinction between scientific theories and scientific laws. Understanding of the distinction between these two concepts, which belong to the nature of science, has been receiving little attention. We surveyed thirty-two students from a local high school with three-part, open-ended questionnaire. The result revealed that these students shared common misconceptions such as 'scientific theories are unproven, scientific laws are proven and absolute', and 'if a theory is proven with enough evidence, it becomes a law'. Moreover, students tend to regard earth science less sophisticated than physical science, because they recognize a lot of its theories to be unproven in their view. It is indicated further that teaching the difference between scientific theories and laws explicitly could help students possess more appropriate view toward earth science.

  • 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.
