This study explores Korean youths' gender equality consciousness in an attempt to search for a way to increase youth's gender equality consciousness. First, this study carries out a survey of youths' gender equality consciousness based on questionnaires collected from a nationwide sample. Second, this study attempts to identify key points needed to evaluate youths' gender equality consciousness in terms of youths' general values. The data used for this survey is from the survey on youths' values conducted by Korean Institute for Health and Social Affairs in 2006 with a sample of 11,240 students from 132 schools nationwide. As a result, youths in 2006 had higher gender equality consciousness than that of previous years(2002). Especially, the support for the fair share of domestic work in the house by youths was significantly increased than the past. However, the survey of youths' values showed clear gender gaps in general attitudes of youths including gender equality consciousness. Female students not only had higher gender equality consciousness than male students but also had higher levels of 'universal value' which would allow one to become sensitive to discrimination and 'self development and achievement value'. In contrast, male students scored high on 'power-oriented value' related to discriminatory attitudes. Therefore, the study recommends focusing on alleviating the gender gaps through school education and other various media education.

The purpose of this study is to investigate differences in learning flow and teaching presence according to the lecturer's appearance and the lecturer's speech rate. For this experiment, 183 freshman students from Xingtai University in China were selected as subjects of the experiment, and a total of four types of lecture videos were developed to test the lecturer's appearance and their speech rates. Data was analyzed through multivariate analysis of variance. According to the results of the analysis, first, learning flow and teaching presence of groups who experienced the presence of the lecturer appeared were significantly higher than the groups who learned without the appearance of the lecturer. Second, the groups who learned from videos with a fast speech rate showed higher learning flow and teaching presence than the group who learned at a slow speech rate. Third, there were no significant differences in both learning flow and teaching presence according to the lecturer's appearance and speech rate. This result provides a theoretical and practical basis for developing customized videos according to learners' characteristics.

This study investigated the song-induced autobiographical memory of patients with early Alzheimer's Dementia (AD) by comparing the effects of patient-selected songs (M-AD) versus music therapist-selected songs (M-MT). A total of 19 patients with early AD participated in this study. In the M-AD and M-MT conditions, each participant listened to a song and was instructed to recall memory. The time to recall memory, the specificity of the memory, mood changes, and the type of recalled memory were measured. Perceived familiarity and preference of the used songs and association of the song with the recalled memory were also analyzed. The results of the study showed that the M-AD condition elicited more specific memory and positive mood change than the M-MT condition. In addition, AD patients reported a higher level of familiarity with and preference of songs in the M-AD condition, compared to the M-MT condition. These results indicate that patient-selected songs, which have a personal meaning to an individual, could be effectively used for intervening with memory of this population, which would support music therapists to make better decision with regard to song selection. Further studies would be needed to deepen the understanding of autobiographical memory in older population with cognitive impairment and to propose more effective music therapy strategies for intervening with memory.

The purpose of this study is to examine the importance of entrepreneurs' well-being, and to propose several ways to improve it. First, the factors influencing entrepreneurs' well-being were explored via previous literature review, and positive psychological capital based on positive psychology was selected as the main factor. In addition, the hypotheses were formulated and the research model was constructed by selecting authentic leadership, mastery goal orientation, and social support as the antecedents predictably associated with positive psychological capital. To empirically analyze the proposed model, a questionnaire survey was conducted for the entrepreneurs who fulfilled the training/coaching/consulting programs offered by the Youth Startup Academy. By using the collected 133 responses, PLS-Structural Equation Analysis, PLS-Multi Group Analysis(MGA), and PLS-Importance-Performance Map Analysis(IPMA) were performed. As a result, it was found that positive psychological capital had a high causal relationship with the well-being of entrepreneurs; and authentic leadership and mastery goal orientation had a positive effect on positive psychological capital. However, the statistical significance of the impact of social support has not been verified. While differences in causality between early and growing stages of start-ups only acted as sub-factors of positive psychological capital, the aforementioned three antecedents showed a significant difference for hope and optimism, respectively. This study expanded the topic of entrepreneurship-related research, which mostly focuses on identifying the performance factors of start-ups. It is meaningful in that it empirically verified the causality model constructed by exploring the factors with respect to the mental well-being of entrepreneurs, which is a main theme in the entrepreneurship-related research. These results found in the current study will render practical insights to entrepreneurs, researchers, and educators.

The purpose of this study was to develop a scenario suited for our clinical situations and evaluate the application possibility by evaluating students' problem solving ability and learning satisfaction in simulation learning. This study consisted of contents which could be applied for varied situations such as complications and symptoms related to liver cirrhosis, looking into hyperkalemia symptoms of patients with liver cirrhosis in emergency unit. The stage of developing scenario was organized in the order of setting simulation learning objectives and situations of scenario, making algorithm, writing checklists of clinical performance appraisal, and debriefing. The scenario was constructed with monitor setting(actions), patient/mannequin(actions), expected interventions(events), and cues in chronological order, according to the scenario progression outline of Jeffries (2007). The scenario was used in 2011, consisting of 4-5 people per group of 53 senior nursing students who registered for 'clinical performance appraisal' course. The problem solving ability improved from a score of 4.05 before simulation learning to a score of 4.30 after simulation learning (t=-3.97, p<.001). The score for learning satisfaction after the simulation learning was high (4.09/5). Considering that simulation learning encouraged students to be the main body of class, this learning method can be the effective way of nursing education.
