  • Purpose: The purpose of this study was to explore the experiences of nursing students in Korea who used concept mapping for understanding pathophysiology. Methods: The data were collected using an open-ended questionnaire from 83 sophomore nursing students after studying concept mapping in pathophysiology class. Each group consisted of five nursing students submitting four concept maps regarding cell injury, inflammation, infection, and neoplasm. After familiarity with concept mapping, the participants wrote their experiences anonymously on sheets of paper. The submitted materials were analyzed via qualitative content analysis. Results: The collected materials were classified into 3 themes, 8 categories, and 18 subcategories. Three themes emerged: (1) awareness of capabilities, (2) difficulties of completion, and (3) benefits of application. Conclusion: The study revealed that participants experienced self-capabilities, and the difficulties and benefits of concept mapping. Concept mapping also provided the opportunity for nursing students to realize communication skill improvement by active group discussion within a group.

  • In this study, we examine whether the description of the elementary science curriculum guide, the concept of evolution, and the beliefs of teachers affect the teaching practice in classes related to adaptation of elementary school teachers. First, we examined the alternative concept among the sentences described in the bio-adaptation-related unit of the 2009 Elementary Science Curriculum Teacher's Guide and identified the effects of this description on the teaching practice of elementary school teachers. Next, six elementary school teachers were classified according to the results of the evolutionary concept test paper and the evolutionary belief test paper, and based on the class recording data and interview data, whether there is a difference in teaching execution. As a result, it was confirmed that there were a total of 18 descriptions corresponding to the concept of evolutionary alternatives in the analysis of instruction descriptions, and that these descriptions influenced elementary school teachers' adaptation concepts and teaching practice. Next, the group with high and low levels of evolution differ in the areas of "recognition of importance in the unit, distinction between adaptation concepts in the general sense and adaptation concepts in the biological sense, errors in the class," and "recognition of evolutionary education needs in the elementary curriculum." This study is meaningful in that it qualitatively confirms the research on the evolution concept of elementary school teachers, which has been approached quantitatively, and in-depth, confirms how the description, evolution concepts, and evolutionary beliefs affect elementary school teachers' biological adaptation concepts.

  • The purpose of this study was to analyze the concept of physical activity. The method was based on the steps of concept analysis by Walker and Avant(1988). The result of this study were as follows; Upon the concept analysis, physical activity is defined as a series of bodily movements which is performed voluntarily by individual. The defining attributes of physical activity were a series of bodily movements, energy expenditure, goal-directedness, and self-control of the body. The antecedents of physical activity were neuromusculoskeletal function, cardiopulmonary function and cognitive function. And the consequences of physical activity were improvement of physical function, induction of fatigue, and need(physiopsychosocial) satisfaction. Further studies are needed to develop the concept of physical activity using the Hybrid model. In addition, considering personal characteristics it is important to study the facilitating factors of physical activity.

  • This study had its objective to indentify the basic biological concepts as recommended by scholars in biology and by high school biology teachers for inclussion in the high school biology curriculum and to determine the importance levels of the concepts. The scholars for this study were selected to insure that their majors are evenly distributed across the biological areas. The final concept list contains 137 biological concepts along with their importance level judged by the scholars and high school biology teachers. The biological concepts are categorized into 12 biological areas. This study suggests that the concepts in the final list can not refect the conceptual hierarchy or inclusiveness, goals or objectives of biology education in the high school, and difficulty levels of the concepts. This study also claims that the concept list like the one produced by this study should be successively' checked and revised due to the continuous development of biological knowledge system and the constant change in the meanings of the knowledge system.

  • The purpose of the present study was to investigate an appropriate instructional model in order to remedy students' misconception. As hypotheses of this study, three instructional models, cognitive conflicting, hypothesis testing, and learning cycle models, on biological 'osmosis' concept were tested in 176 high school students. Results of the present study are as follows: 1. All groups used one of three instructional models showed a statistically significant improvement in conceptual change on the 'osmosis' concept between before and after the instruction. In addition, the three hypothesized instructional models were more effective in conceptual change than a traditional expository instruction. 2. There was a statistically significant difference among three experimental groups. Cognitive conflicting model and hypothesis testing model was more effective than learning cycle models. 3. An interviewing after instruction showed that students who had scientific concept on the 'osmosis' through the instruction could effectively apply the concept to other context more than students who had no scientific concept through instruction. The present study indicated that instructional model play an important role on students' conceptual change in science classroom. According to the result of this study, the instruction emphasizing students' active participation in class and scientific reasoning process is more appropriate to remedy misconception that the instruction using students' passive participation in class and expository teaching procedure. This study also indicated that students' concept acquired through instruction is one of important factors to apply it to other context.

  • Doris Lessing, who considers science and technology as instruments of capitalism, deals with the theme of 'biological evolution' in The Sirian Experiments, the third book in the Canopus in Argos: Archives series. One of her themes that repeats throughout is that of 'spiritual evolution,' and in The Four-Gated City she even used 'biological evolution' as its metaphor. This paper analyzes The Sirian Experiments using scientific knowledge such as the concept of 'biological evolution' from Charles Darwin's evolution theory and Edward O. Wilson's sociobiology. Lessing concludes that while 'biological evolution' not accompanied with 'spiritual evolution' puts humans in existential problems and mental breakdown, the one in equilibrium with the other can bring social and political revolution. Lessing's concept of 'spiritual evolution' is basically a product of her holistic view and her own philosophical view that human evolution is a necessary process following the Universal Order, which shows that she is influenced by Sufism. The basic tenet in Sufi philosophy is to achieve equilibrium between the rational and non-rational modes of consciousness. Lessing incorporates her rational and irrational ideas into The Sirian Experiments to make a field for confluence where the biological, the sociological, and the spiritual thinking converge.

  • It is over 100 years after Lee Je Ma has proposed concept of the Sasang constitutional medicine in his book DongEuiSooSeBoWon in 1894. As well known, this concept describes four constitution of Taeyang, Taeum, Soyang, and Soeum which are deals with physical body status and shape, desease and symptoms, personal characters, and organ function. In these days there are growing needs to elucidate this Sasang concept by the scientific manner, especially by biological tools. However there are no genes revealed related to the Sasang and moreover it is not easy to give a biological evidence for the Sasang constitution. Here are some considerations about the brief history of biological research on the Sasang constitution, and some prospectives of how to do to find genes of Sasang, and which to be done for what is about Sasang.

  • Recent studies on long-term outcome of schizophrenia revealed that schizophrenic symptoms recover in more than 50%, while it remains severe in less than 20% after 20 years or more from the onset. Psychopharmacological studies indicate that 75% of remitted schizophrenics may recur within 2 years after discontinuation of maintenance pharmacotherapy. In addition, family studies revealed that schizophrenic decompensation may occur significantly more frequent in discharged patients with high expressed emotion family than in low expressed emotion family. These findings strongly support a clinical validity of stress-vulnerability concept of schizophrenia which open a new viewpoint to two central problems in schizophrenia treatment, i.e. psychotic relapses and chronification of the fist episode schizophrenia. Moreover, recent psychopathological studies argue that schizophrenic symptoms are manifestations of psychological reaction secondary to a primary cognitive impairment(neurobiological vulnerability), which is originated in neurobiological changes in the brain. Recent approaches to the vulnerability to schizophrenic symptoms or schizophrenic decompensation are reviewed.

  • Objectives: This study aims to investigate the concept of microplastics and their occurrence, transport, biological effects, and management methods in the ocean. Methods: I reviewed articles on microplastics in the ocean by using the Google Scholar database. Results: Plastic litter has been reported as a ubiquitous pollutant in the ocean due to the extensive consumption of plastics and the mismanagement of plastic wastes. Microplastics are generally defined as synthetic polymer particles <5 mm in size. Microplastics generated from the degradation of plastic litter are currently a serious global concern since they spread easily all over the ocean, transfer to different tissues inside contaminated animals, and even across different trophic levels inside the food web. An additional concern is the ability of microplastics to adsorb organic and inorganic pollutants and subsequently release them into the ocean. Thus, alternatives to reduce microplastics in the ocean are discussed. Conclusions: This paper summarizes the concept of microplastics and their behavior in the ocean and suggests management methods for microplastics in support of a cleaner ocean.

  • Treatment of schizophrenia is one of the most challenging areas in the field of psychiatry. There has been much improvement in psycho-pharmacotherapy, and at present, psycho-pharmacotherapy along with milieu therapy and social rehabilitation is the standard first-line treatment for schizophrenia. Healing environment, a concept which has arisen from the architectural field, has similarities in meaning to milieu therapy in psychiatry. In other words, healing environment may be an encountering point between psychiatry and architecture. In this encountering, each field can understand each other and expand its concept to aid the treatment of schizophrenia and to plan the build-up of the entire environment considering its social and psychological effects. In this paper, we aim to establish the basic concept of healing environment to alleviate the psychopathologies in schizophrenic patients. We worked under the premise that physical setting affects human behavior and mind, and that physical setting should play a role as a medium with therapeutic potential for patients with medical problems. The aims of this paper are as follows. First, theoretical discussion of the concept and the constructs of healing environment : second, understanding of the schizophrenic symptoms that may be affected by supporting environment : and third, discussion of supporting environment that may alleviate the symptoms of schizophrenia.
