In order to help students to understand the essence of prime concepts, this study looked at the history of prime concept development and analyzed how to introduce the concept of textbooks. In ancient Greece, primes were multiplicative atoms. At that time, the unit was not a number, but the development of decimal representations led to the integration of the unit into the number, which raised the issue of primality of 1. Based on the uniqueness of factorization into prime factor, 1 was excluded from the prime, and after that, the concept of prime of the atomic context and the irreducible concept of the divisor context are established. The history of the development of prime concepts clearly reveals that the fact that prime is the multiplicative atom is the essence of the concept. As a result of analyzing the textbooks, the textbook has problems of not introducing the concept essence by introducing the concept of prime into a shaped perspectives or using game, and the problem that the transition to analytic concept definition is radical after the introduction of the concept. Based on the results of the analysis, we have provided several pedagogical implications for helping to focus on a conceptual aspect of prime number.

The goals of nursing education, and the bases for evaluating them depend on the goals of nursing practice. In order to prepare for the coming twenty first century and the meet changing societal demands and health needs, it is necessary to develop a new conceptual framework for future nursing education. While hospitals will still be in significant components of the health care system, will no longer be central focus or dominant influence. Health care services will be more usually delivered at community base. The nursing education required by that new approach must provide for reconsidered about a concept of caring as nursing curriculum. The changes in health care delivery that have occured, now being proposed, for nursing education undergoing its own changes. So the philosophy and objectives of education meed to reconsidering about the caring concept and general nursing. Nurse educators must prepare students to practic in condition of constant change. At the same time nurse educators must emphasize preparation about that. The practice of science of caring in nursing draws on a basic knowledge of the behavioral knowledge, biophysical processes, pathological processes, nursing skills and procedures and various treatment regimes and problem solving to help decision making in nursing situations. The concept of care is probably one of the least understood ideas used by professional and nonprofessional people, yet it is probably one of the most improtant concepts to be understood by nursing. Human caring and human relationships are closely interrelated. Humn caring remains an essential dimension of professional work and the science of caring as essental to the discipline of nursing. It is expected that the objectives of nursing education will be accomplished when the course and content of the curriculum are based on this conceptual framework. One recurrent education goal with some consistency is that of equipping the student with the necessary skills to live effectively and productivly in the world of tomorrow. In the new vision we are developing, professional education must also include exposure to liberal arts, encouragement of critical thinking, and a moral context for advanced professional education that is based upon a contextual health policy and caring science educational model.

Purpose: The purpose of this study was to explore the clear concept of organizational commitment for effective nursing personnel management. Method: This study was conducted using Walker & Avant's conceptual analysis framework(2005). Results: Organizational commitment was identified with six attributes: acknowledgment, acceptance, trust, sacrifice, attachment, regulation. Antecedents of organizational commitment were personal characteristics, perceived organizational support, empowerment, fair compensation, job satisfaction, job autonomy, organizational culture, and leadership. Consequences of organizational commitment were turnover intention, job performance and organizational citizenship behavior. Conclusion: Organization commitment is a core concept for understanding the management of nursing personnel. Appropriate instruments to operationalize the concept of organizational commitment including six attributes need to be developed.

The purposes of this study are how to consider the concept of magnetization by fifth elementary school students and how to change conceptions of students after the experiment with developed experiment sets. Personal interviews to the students were used for this study. to probe the conceptions of them, it allowed them to make gestures and to draw pictures through interview. From the analyses of the interview data, following results were found. Students have mostly understood the concept of magnetization, but have not remembered the term itself. And, the students believe that iron is magnetized only if iron was directly contacted a magnet. After the experiment, the students understand that iron could be also magnetized without direct contact to a magnet. And also, they could explain magnetization of iron powder around a magnet by applying the concept of magnetization. This new experiment is a good tool to understand concepts of magnetism.

Health is an important concept within the health component of nursing paradigm. And health concept is a core component to determine health behavior according to individual's health perception. Health habits during the period of university student will be affecting health behavior of the adult period. The purpose of this study was to analyze health concept of the university students in Korea and to provide the strategy of health care for the university students. The method of this research was a descriptive study using a self-report questionaire. The subjects were 301 students of university and their age was from 19 to 30. The results of this study were as follows: 1. Health concepts perceived by the university students were 'wholeness without difficulty', 'vitality', 'harmony', 'comfort', 'Good condition and fitness of physical and psychological condition', 'soundness', 'happiness', 'enabling' 'smoothness'. 2. Health was perceived by the subjects as an essential and an important component of life.

We define and study a concept of $H^f-space$ for a map, which is a generalized concept of an H-space, in terms of the Gottlieb set for a map. For a principal fibration $E_{\kappa}{\rightarrow}X$ induced by ${\kappa}:X{\rightarrow}X'\;from\;{\epsilon}:\;PX'{\rightarrow}X'$, we can obtain a sufficient condition to having an $H^{\bar{f}}-structure\;on\;E_{\kappa}$, which is a generalization of Stasheff's result [17]. Also, we define and study a concept of $co-H^g-space$ for a map, which is a dual concept of $H^f-space$ for a map. Also, we get a dual result which is a generalization of Hilton, Mislin and Roitberg's result [6].

The context and intuitive understanding is very important in Statistics Education. Especially, there is a need to mitigate student's difficulty in studying probability density function. One of teaching method this concept is to using relative frequency histogram. But, as using this method, we should know several problems included in that. This study investigate problems in the method for teaching probability density function as gradual meaning of histogram. Also, as alternative approach, this thesis introduce the density curve concept. The application of four methods to teach the concept of the probability density function and analysis of the survey result is done in this research.

The purpose of this study was to suggest that the history of science be introduced to students in the secondary school to help understand the developmental process of the scientific concepts, especially the concept 'heat'. Reviewing the national and international researches related to students' concept 'heat' revealed that many students tend to grasp the wrong concept of heat based on the caloric theory. Studies on definitions and explanations of the concept 'heat' and related concepts in secondary school science textbooks indicated that the way 'heat' was described could not help students to correct their misconceptions. In conclusion we need to include the historical and developmental process of scientific concepts such as heat in textbooks.

Purpose: The purpose of this study is a) to develop a self-awareness program using various action methods and b) to experiment the effects of that on self-concept, the self-perception and the self-esteem in nursing students. Method: The subjects of this study were 37 nursing students. Using one-group pretest-posttest quasi-experimental research design, we conducted the experiments of a self-awareness program during the period of six weeks from March through May of 2004. Results: The scores of the posttest on self-concept, self-perception and self-esteem in nursing students were significantly higher than those scores of the pro-test. Conclusion: The results of our experimentation showed that a self-awareness program using various action methods was very effective to enhance self-concept, self-perception and self-esteem in nursing students. In particular, different action methods of psychodrama were shown to be a useful tool in exploring the areas of blind self and unknown self.
