  • Game theory is adapted to a variety of domains such as economics, biology, engineering, political science, computer science, and philosophy in order to analyze economic behaviors. This research is an application of game theory to wireless communication. In particular, in terms of bargaining game we dealt with a multimedia resource allocation problem in wireless communication, which is rapidly spreading such as Wibro, WCDML, IPTV, etc. The algorithm is assumed to allocate multimedia resources to users who can choose and access differentiated media services. For this purpose, 3 utility function of users is devised to reflect quality of service (QoS) and price. We illustrated experimental results with synthesis data which were made to mimic real multimedia data, and analyzed differentiated service providing and the effect of the utility function.

  • The purpose of this study is to identify the teaching professionalism of the two teachers for secondary science-gifted students in perspective of teaching orientations. Both teachers have been taught biology to secondary science-gifted students for more than six years and they have received in-service training in gifted education. Teachers' orientations were investigated through in-depth interviews and observing lessons. For the data collection, videotapes were recorded during two lessons and two in-depth interviews for each participant were conducted. All recorded data were carefully transcribed and analyzed. Some unique characteristics of teaching were identified from the class instruction of each participant. Both teachers revealed 'Open Inquiry' orientation. This was reflected by their educational goals and beliefs that they should help science-gifted students to grow themselves as scientists by enhancing their inquisitiveness and creative problem solving ability. However, each teacher had shown different teaching orientations such as 'Academic Rigor' and 'Discovery' that seemed to have influence on the level or the range of subject matter covered in the classes. Teachers' science teaching orientations have been changed by their subject of teaching and their experiences in teaching the gifted. In the process, teachers' educational philosophy about gifted education plays an important role in teaching orientation. Based on the ongoing teachers' efforts for enhancing his/her professionalism, the teachers seemed to critically review theoretical knowledge of the science teachers in gifted education through self-reflection on their own teaching methods. When teacher's educational philosophy about gifted education was established and internalized, science teaching orientations in teaching practice seemed to be consistent with his/her goal of teaching.

  • Traditional Chinese cuisine, which is highly evaluated with respect of taste and techniques, is built based on a sound healthy philosophy and distinct dietary culture, with emphasis on the unity of human beings and nature. The traditional cuisine utilized food materials according to the physical status and seasons, which is still a valuable principle in the modem diet. According to relevant research, the nutrient retention in Chinese cooking is acceptable. However, following the rapid growth of domestic economy, the Chinese diet is in danger of losing its original merits, especially when eating out. The excessive desire for food enjoyment leads to a rapid increase in the prevalence of obesity and chronic disease. It is a critical point to review the characteristic of traditional Chinese cuisine and lead the trend to a healthy direction.

  • When recognition of the Ghi(氣) which exist in all things, is changed on the aspects of the science of nursing, the view of health and nursing will be more efficient and can be developed as the proper concept for Korean culture. I think it is nessary to confirm which philosophical basis of the will be applicable to nursing and how to it has to be developed. Therefore I can for the research of the Ghi phenomena to attain the Thoughts of philosophy that is appropriate to expound those phenomena. And I attempt to induct "the fusion of horizons" to unify the view of the I world between Korea and the West. The Ghi is very energetic and omnipresent among the universe, Nature, and the human being. So it can organize all the primary elements of mental and I physical function of human as like life, mind, breath, feeling, energy, etc. A general concept of the Ghi is described as follows ; (1) The Ghi is the origin and essence to organize the universe, Nature, and the human being. (2) It is the perpetually movable thing. (3) And there are continuous transmission between the Ghi of the universe and the human through 'body, mind, and soul. For review on the philosophic basis of the Ghi, I studied out the identity of the doctrine of Li and Ch'i(理氣論) in the field of philosophy of Korea and the West. In Korea, the concept of the Vigor is based on Ch'i monolism(기일원론) and Li Ch'i dualism (이기이원론) of Yul-gok Lee's, Toi-kye Lee's, Hwa-dam's, and/or Hekang's. These are indispensable for the view of the world of Korea as Metaphysical ideology, Concrete science, Materialism, Ontology, and Epistemology. From the viewpoint of the philosophy of the West, the doctrine of Li and Ch'i(이기론) of Korea is identical with the doctrine of Li and Ch'i(이기론) of Joo-ja, Idea of Plato, Metaphysics of Aristotle, World Spirit(Weltgeist) of Hegel, and Existentialism of Heidegger. In the nursing theory of the West, some of them referred to the Ghi as like Energy field theory of Rogers and Energy exchange of Neuman. Though there are different in terminology, "energy" and the "Ghi" are induced comparable therapeutic action between the human and the environments. With the nursing theory of Korea, I have made an attempt to compare the Ghi with metaparadigm of nursing-the human being, the environment, the health, and the nursing. For the most part, the alternative therapy is resonable to the frame of the nursing theory of Korea. It is easy to apply alternative therapy on the every spot of nursing. So this therapy could be a kind of forms as nursing therapy in the nursing centers where take the duties of supporting in local societies. In result, independent nursing intervention will be activated by the nurse who puts up with the major parts. It is available to apply this therapy to palliation of pain, insomnia of infant, Sanhujori (산후조리), pain of menstruation, arthritis. And the alternative therapy makes it possible to propose the nursing model which represent originality, tradition, and history of the nursing of Korea. Additionally, in the field of the nursing, it is indispensable to choose a suitable methodology which is considered whether it is matched with a theory of philosophy in the boundary and object of the research. Because there are many way to get the knowledge of nursing related to the Ghi. In the science of nursing, context of sociocultural background and frame are required to understand the person who need to take care of (nursing client). But the value systems of the West and the East are distinctive each other as well as the behavior of health persuance. Therefore it is the basic research data of great worth to review philosophical the Ghi phenomena which is well known to Korean.

  • A considerable change of the Korean nursing system has been made during the last decade not only in its philosophy but also in its function and structure to meet political and scientific need of the modern society. The main purpose of this study is to develope the new concept of comprehensive nursing care, both its Philosophy and ethics, as the basic of modern clinical nursing theory and practice. Comprehensive nursing care is the concept of human centered nursing care, and it helps a man to meet the basic physical, psychological, environmental, socioeconomic and teaching needs. It also helps him to help himself to meet these needs. This concept starts from the individualized nursing care and its ultimate goal is to improve a man to have a better position in his own community so that he may able to have a meaningful life. To accomplish this goal, an individualized nursing care plan as a nursing diagnosis and problem solving method should be set up for different patients with similar diagnosis to meet their needs, because each patient has a different social background. from this viewpoint, nursing is a science as well as abstruse humanity. The performance of comprehensive nursing care is a goal and issue of modern clinical nursing care. If nursing is a science and a profession for man, it should have ethics which recognize the dignity of man and offers infinite service voluntarily, and should be able to show leadership in carrying out the nursing responsibility. This leadership finds a person's potential and encourages him to utilize it. Such concepts should develop into a nursing ideology and this ideology should become a priority in comprehensive nursing care. The following statements are the conclusion of this study. 1) Modern nursing has been developed from disease centered nursing care to comprehensive nursing care based on humanity. The primary principle of nursing was to assist in the treatment of disease, but it has been changed to the professional nursing system independently. 2) The concept of nursing is one of continuous or endless scope of dispersion. It proves that nursing is grasping the professional responsibility to be able to coordinate scientific principles Patient health problems are according to scientific principles rather than adhering to nursing technical discipline as a daily work. 3) In chapter I and Ⅱ, the philosophy and ideology of nursing have been discussed and the flow of concept of clinical nursing and the rate of progress which emerges from naturalizing performance of the concept of comprehensive nursing in clinical nursing studied. The discussion developed the theory that a nurse should be to embody nursing ideas and objectives by establishing definite conviction of professions and study. 4) In chapter lil, nursing planning based on nursing diagnosis as a method to attain ideal nursing care for humanity with a definite idea of establishing philosophy of nursing was presented. 5) From the result of survey on patient needs about treatment and nursing, it was observed that all patient had emotional stress from unknown factors. Therefore it was concluded that nurses should not only educate the patient but also give them the opportunity to communicate freely their needs and anxieties. Furthermore complaints and doubts of the patient should be carefully noted and must be considered to meet these needs. 6) Patient teaching is the most important part of comprehensive nursing care. In chapter, Ⅲ, the important of patient teaching was emphasized by demonstrating the effect of patient teaching for diabetic patient. 7) In Chapter Ⅳ, from the result of the study on nurses attitudes to comprehensive nursing care, it was pointed that the evolution of nursing education and the establishment of a complete concept and value of comprehensive nursing was necessary.
