The purpose of this study was to assess preschool children's understanding of contagion and their use of immanent justice explanation for illness and accidents, 124 children (66 four-year-olds and 58 five-year-olds) were interviewed individually by two female interviewers. The data were analyzed by ${\chi}^2$ and correlation. Preliminary analyses revealed no significant sex and age differences: Therefore, the data were collapsed across sex and age for all further analyses. The results showed that preschool children have a concept of contagion as a cause of illness, and they understand the effect of distance between people on the likelihood of transmitting contagious ailments. They overextend the concept of contagion to inappropriate ailments: that is, to noncontagious illnesses and to accidents. They employed immanent justice explanations for all illnesses (contagious and noncontagious) and accidents.The use of immanent justice was inversely related to application of the concept of contagion.

Purpose. The purpose of this study was to obtain a clearer understanding of spirituality and examine the process of spirituality through defining the meaning and attributes of spirituality. Method. Concept analysis was done in the three phases, theoretical phase, fieldwork phase, and analytical phase suggested in the Hybrid Model. Five people participated in the fieldwork phase. Results. Spirituality is activated through self-awareness which occurs as spirit being activated through self-introspection, and through restoration of the relationship with Supreme Being. This interconnectedness with Supreme Being has an absolute impact on one's harmonious interconnectedness with self and neighbors, thus leads all the critical attributes of spirituality to be revealed. The core energy of this harmonious inter-connectedness is love. When activated, it has a great impact on an individual as integrative energy, leads one to go beyond everyday experience as well as to have new perspectives, and to live a satisfactory life in every aspect. Conclusion. The results of this study suggest that promotion of connectedness is the most important element in spiritual nursing interventions. The results can also be used effectively in developing spirituality assessment scales and theory.

This article introduces a proposed lesson to help younger or lower level mathematics students conceptualize area. The objective for the proposed lesson was for the student to demonstrate an understanding of the concept of area by identifying the area, in square units, of polygons drawn on computer dot board constructed by computer software, Geometer's Sketchpad. The concept of covering is the key to develop the concept of the area. The article proceeded from rectangular figures, to right-triangular figures, to non-right triangular figures, then to polygons to find the area and develop the formula for the area of the figures. It is meaningful that this kind of materials can be developed within interactive computer environment since students feel successful in loaming and teachers use them directly in their measurement classes.

Fatigue is a universally common word. The subject has been studied in different disciplines, but the basic concept of the term still remains unidentified. It becomes especially important for the medical communications between nurses and clients. Based on the framework outlined by Walker and Avant (1995), this analysis attempts to clarify and examine the symptoms of fatigue. The attributes of fatigue identified in this paper were exhaustion, weighted psychological burden, shortage in capacity or lack of energy, shortage incapacity(motivation and excitement), and imbalance of energy. Therefore, the definition of fatigue refers to a subjective feeling from various internal or external stresses. The consequences of fatigue bring reduced capacity and imbalance of energy. The symptoms show a homeostatic disability or shortage of capacity (physical, psychological, environmental and physiological factors). A precise understanding of "fatigue" will be utilized in defining the causes and measuring outcomes. Also, it will enhance the effective medical communications with client s and nurses. In conclusion, more work is needed to develop objective measurement and effect ivenursing intervention.

The unit fraction is the basis of the fraction concept and has a role of starting point for understanding the fraction concept. In this study, in terms of the importance of the unit fraction, the teaching methods of the fraction based on the unit fraction were explored. First, it was examined the emerging contexts of the fraction concept and the diversity of its meanings. Second, it was investigated the contents of the unit fraction in Korean and CCSSM's curriculum and textbooks. Lastly, I suggested the teaching methods using the unit fraction in terms of the introduction of fraction, fractional operations, and teaching of problem solving based on the unit fraction.

The concept map is the diagram of two dimensions which hierachically arrays main concepts from those of the textbook and shows their relations. The research analyzed five of the ten high school earthscience textbooks approved by the Minister of Education according to the 6th reformed curriculum in 1995, one of which this research chose to make out the concept maps. The chapter [III. the Universe] contains the outer space of the earth presents new concepts about the stars and the universe and introduces the latest research in astronomy. This study changed textbook contents into Novak's concept map, searched for concepts requiring complement for learners in oder to obtain concepts from those of the textbook and pointed out problems on the basis of that result still better concept map is set up. We have the following conclusions. First, it is necessary to rule out unnecessary small units so as to make more effective understanding and to rearrange the units to have relation to contents. Second, the higher concept and lower concept need to be rearranged systematically in making an array of textbook contents. Third, the concept should have something to do with learners' experences and consciousness by showing learners the real examples relevant to the concept for the link between them.

In order to confirm ecological validity of D$\ddot{o}$rnyei's second language motivational self, the present study investigated 495 South Korean secondary school students' L2 learning motivation and motivated behavior by using a questionnaire survey. The participants' ideal L2 self, ought-to L2 self, integrativeness, and instrumentality were examined and compared to identify which motivational factor had the most effect on their motivated L2 learning behavior. Among Korean secondary school students, the concept of integrativeness was replaced with the ideal L2 self as a more appropriate concept for understanding Korean secondary school students' L2 learning motivation. As for instrumentality, promotional aspects demonstrated a significant correlation with both the ideal and ought-to L2 selves, whereas preventional aspects showed a relatively high correlation with the ought-to L2 self. The ideal L2 self had the most impact on the motivated behavior, and the ideal L2 self and ought-to L2 self reflected the students' different motivational characteristics. It is suggested that D$\ddot{o}$rnyei's (2005, 2009) L2 motivational self system can be a better psychological model than Gardner's (1985) socio-educational model for understanding Korean secondary school students' L2 learning motivation.
