In Korea, the lower elementary grades are applying a topic-oriented integrated curriculum. It causes a lack of science content and inquiry experience for young children. The purpose of this study is to understand the scientific experiences and perceptions of the lower elementary graders and to inquire about the meaning of those experiences in their science learning. Four students (male 2, female 2), their parents, and their first-year homeroom teachers participated in the study. The data collection was mainly conducted through in-depth interview of them. Results showed that the 'experiments' were the student's the main perception of science, and the epistemic emotion that students mainly feel about science was 'curiousness'. Since most experiences were dependent on non-formal educational experience, the parents were an important factor to determine their experiences about science. Various factors, such as students' scientific experiences, their epistemic emotions, and the parents, interacted to form children's perception of science. The positive perception of science affected the level of motivation and expectation for science learning as the third grade. It is suggested that improvement of curriculum and textbooks should emphasize scientific exploration for the lower graders of elementary school, which provides them meaningful scientific experience in school.

Load forecasting is an important issue as for the economic dispatch and there have been many researches which are classfied into two classes, time series method and factor analysis method. But the former is not adaptive for a sudden change of a correlated factor and the latter is not inefficient as the factor estimation is not easy. To make matters worse, both of them are not good for the estimation of special days. It is because the load forecasting is not a problem modeled precisely in mathematics, but a problem requires experience and knowledge those can solve it case by case. In this viewpoint, an expert system is proposed which can use complicated experience of an expert by use of fuzzy decision.

This study examines how experience diversity of chief technology officer (CTO) drives radical innovation of the firm, and the moderation effect of group attributes of top management team. Using data of 148 firms in U.S. manufacturing industries, this study finds that a CTO's diverse functional experience increases a firm radicalness, and diverse industrial experience also increases the radicalness. This study also examined the moderating effect of top management team (TMT) characteristics such as TMT size, TMT tenure, and gender composition in TMT. The positive relationship of CTO knowledge diversity and firm radicalness is weakened as TMT size or TMT tenure increased while the relationship is strengthened as gender diversity in TMT increased. These results of the analysis of firm-level radicalness provide implications for both academics and practitioners.

Purpose: The purpose of this study was to describe nurses' experience of health communication with doctors in the clinical fields. Methods: Eight experienced clinical nurses working in various units of general hospitals participated. Data were collected through in-depth individual interviews and analyzed using the Colaizzi' method. Results: Five themes of nurses' experience of communication were identified: exploring the speaker seriously, becoming aware of emotions and controlling them, developing relationships after lining up for battle, having superficial and withered relationships with doctors, having few resources to promote communications with doctors. Conclusion: The results of the study indicate that humanistic and warm interpersonal relationships and genuine sharing of information are necessary to ensure effective communication. Thus, practice guidelines should be re-evaluated and developed to meet the proposed standards; safety-net programs and education for health communication should also be established. Nurse managers should create a high-touch work environment.

This study estimated a structural model for examining causal relationships among flagship store experiences, store emotion and loyalty, and to compare the structural models between luxury and fast fashion SPA brands. A total of 416 responses were collected from consumers who had experience with a variety of luxury and SPA flagship stores. Findings confirmed that flagship store experience consisted of four factors, such as sensory, affective, intellectual and behavioral experiences. Sensory and behavioral experiences had positive effects on store emotion that influenced loyalty. Affective and cognitive experiences influenced loyalty. All aspects of experiences explained store emotion or loyalty for luxury flagship stores; however, two of experiences (i.e., sensory and affective) were important to determine store emotion or loyalty for SPA flagship stores. The study discussed managerial implications for fashion brands to develop and manage flagship stores.

This study examined the science learning environments experienced by Korean and U.S. preservice elementary science teachers during their 3-week clinical experience. Observational experiences of 97 Korean and 112 U.S preservice teachers were surveyed with an instrument that we developed for the study. Follow-up interviews provided a clearer picture of what preservice teachers observed and experienced in science classrooms during their clinical experiences. Korean preservice teachers experienced a variety of science teaching environments, whereas the U.S. preservice teachers reported limited opportunities to observe science teaching and learning in terms of 6 identified facets that we posed. Along with our interpretation of the contrast in findings, some of the challenges are discussed in providing preservice teachers with opportunities to observe, experience, and teach in effective science learning environments during the clinical experience.

Purpose: The purpose of this study was to evaluate the effects of Doula support during labor on anxiety, labor pain, and perceived childbirth experience of primiparas. Method: Of 65 primiparas who were hospitalized in LDR from March 1 to September 30, 2007. 32 women were placed in the Doula group and 33 in the control group. VAS was used to measure the degree of labor pain and anxiety in the latent, active, and transitional phases. Perceived childbirth experience was measured within 2 hours after birth. Results: The Doula group had a significantly lower anxiety level than the control group in the active phase (t=-2.13, p=.04) and the transitional phase (t=-3.99, p=.000). The degree of labor pain of the Doula group was significantly lower than that of the control group for the active phase (t=-3.10, p=.003) and the transitional phase (t=-7.24, p=.000). Also, There was no significant difference in perceived childbirth experience between the two groups (t=.19, p=.85). Conclusion: The results of this study show Doula support in LDR decreases not only anxiety of primiparas but also labor pain in the active and transitional phases. Therefore Doula support by nurses in LDR can be a useful intervention during childbirth.

Objective: This study aimed to identify the perceptions of orthodontic treatment among Korean adults and determine the factors that drive them to seek orthodontic treatment. Methods: A total of 2,321 adults aged 19-64 years were surveyed using an internet research system from a specialized research company. The participants were divided into the following groups based on their experience of and willingness to undergo orthodontic treatment: experience, acceptance, and non-acceptance groups. The characteristics of the participants were compared using analysis of variance with post-hoc analysis. Multinomial logistic regression analysis was performed in all three models with the non-acceptance group as a reference. Results: In terms of demographic characteristics, age, gender, marital status, and education had significant influences on orthodontic treatment decisions in adults in the experience and acceptance groups (p < 0.001). When all the factors were analyzed, age, marital status, past dental treatment experience, regular oral examinations, demand for orthodontic treatment, optimal treatment period, health insurance coverage, information on orthodontic treatments, perceptions regarding orthodontic treatment, and psychosocial impact of dental esthetics significantly influenced orthodontic treatment decisions in adults in the experience and acceptance groups (p < 0.001). Conclusions: These findings suggest that various factors influence orthodontic treatment decisions in adults. Individuals who seek orthodontic treatment were found to undergo more regular dental treatment and oral examination than those who did not. They also had a better perception of orthodontic treatment and more negative values for the psychosocial impact of dental esthetics.
