Temperature is an important ambient factor affecting the physiology and metabolism of aquatic invertebrates. In this study, we studied about the survival, reproduction and growth effects of 4 different temperatures(16, 20, 24, $28^{\circ}C$) in four Korean cladoceran, Daphnia sp., Daphnia obtusa, Moina macrocopa, Simocephalus vetulus and Daphnia magna as an international standard species. All 5 water flea tested showed that molting time, fecundity and intrinsic rate of natural increase(r) in high temperature condition were higher than those in lower temperature. On the other hand, lower survivals and longer time to start of offspring were showed in high temperature. Our results suggest that the optimal temperatures of Daphnia sp.,, Moina macrocopa and Simocephalus vetulus seem to be about $20^{\circ}C$ except for Daphnia obtusa which as showed good survivals and reproductions in $16^{\circ}C$.

This study has the purpose to evaluate the effects of cooperative learning applying Jigsaw model in simulation based infection control education by comparing perception of infection control, intrinsic motive and learning satisfaction, 54 first-year health related students. It is composed of 27 students of the experimental group and 27 students of the control group. In order to evaluate the homogeneity between the two groups, it surveyed in advance perception of infection control, intrinsic motive and learning satisfaction. There was no significant difference between the two groups, The education program composed cooperative learning applying Jigsaw Model, simulation practice and debriefing to the experimental group was performed twice for 2 weeks and lecture and skill training, simulation practice and debriefing were performed to the control group. After two-week education, perception of infection control, intrinsic motive and learning satisfaction of the participants the research were surveyed. As a result of this study, the Jigsow Model indicated the perception of infection control and learning satisfaction experimental group was significantly high in statistic. Based on this research result, I suggests that utilization of cooperative learning applying the Jigsaw Model as a strategy to improve the scholatic achievement and learning satisfaction of students in the variable simulation based education.

Although it is never easy to create charming characters that people can relate to, well-formed characters have the power to enable the audience to not only empathize but identify with them. Thus, there is a need for us to examine the parts that make up a well-formed character. According to empathy theory, when the character in the play has a human face that is not different from me, I can feel familiarity and human empathy. Rather than perfection without loopholes, I relate to and sympathize with someone who looks similar to me, with many mistakes and some lack. This study aims to examine the attractiveness of characters in narrative dramas in terms of defects and internal growth. To do this, we tried to compare the setting, evaluation, and performance of characters based on the movie worldviews of two famous brands (DC and Marble), which can be compared directly. I looked at it. In conclusion, the work of hero character but human character setting based on internal growth not only has high evaluation and public evaluation, but also high sales, and thus direct and indirect correlation with the public favorability is significant.

The purpose of this study is to identify the impact of well-being-oriented activities of university students in liberal arts and physical education classes on happiness. First, among well-being-oriented activities, females are more likely to have eco-friendly behavior, well-being-oriented, hobby-orientation and exercise orientation, and males are more likely to be better at purchasing well-being products and mental health. Happiness was found to be higher in boys than in outer happiness, self-controlled happiness, and inner happiness. By grade, there was no difference between men and women in well-being activities, and the happiness showed that the second and third grades were higher than the first grade, while the second and third grade were higher in inner happiness. The happiness level showed that the number of students who attended three sessions showed higher level of happiness. Second, among the well-being activities of students in liberal physical education classes, external happiness shows in hobby-orientation, mental health and exercise orientation. Self-regulating shows in well-being meal, hobby orientation, mental health. Inner happiness shows in well-being meal, hobby orientation, mental orientation and exercise orientation.

The aim of this paper is to explore and understand, using in-depth interviews, the participant's enthusiasm for and involvement in studying mathematics and the deeper nature of his/her interest in mathematics teaching. In addition a larger aim is to understand how the individual's interest in mathematics and teaching are linked to his/her larger personal fulfillment. We conducted in-depth interviews with 4 pre-service teachers' subjective experiences focusing on deep motivation, pedagogical content knowledge, inner vision. Interviews focus much more on the participant's spontaneous feeling, consciousness, and state as these arise in the interview, and on past foiling, consciousness and state as they appear to the participant subjectively retrospectively in his/her memory. The output of this research consists of 2 portraits out of 4 individual participants, highlighting and conceptually developing the specific aspects under study; different ways in which individuals' involvement with the subject area affects their motivation, inner visions and academic efforts toward becoming teachers. Larger aspects of pre-service teachers' subjective experiences were sketched by contrasting the two cases. Several suggestions were put at the end to enhance mathematics education concerning curriculum development.

This study was conducted as a study on the SW career education of students from underprivileged areas, which is a necessary condition for SW education to become a universal education or where research has not been conducted. Therefore, this study conducted a SW career selection model using structural equations for 2,231 students in grades 3 to 6 in 6 schools located in the marginalized areas of eup/myeon. As a result of the study, it was analyzed that the intrinsic SW learning motive of students from underprivileged areas did not affect their SW career choice, whereas the external SW learning motive was analyzed to affect their SW career choice. This is inferred that the intrinsic SW learning motive does not affect the SW career choice due to the lack of SW experience of students in underprivileged areas. The correlation between internal and external SW learning motivation was analyzed to be significant. In the future, as students from the underprivileged class have more SW education experiences, research should be conducted on how internal SW learning motives affect SW career choice and how external SW learning motives support internal SW learning motives.

The purpose of this study is the construction and internal validation of DT ISD model that incorporates Design Thinking process into Instructional Systems Design. The study proceeded in 3 steps. Firstly, literature review was conducted to examine the process and components of Instructional Systems Design model such as ADDIE. Design Thinking models were also reviewed to determine the probability of integrating Design Thinking with ISD. Secondly, DT ISD model was constructed by adopting 3 principles of Design Thinking to ISD process. Thirdly, the internal validation research was conducted through 3 rounds delphi study and DT ISD model was finally validated by experts of instructional technology and lifelong education. DT ISD model is based upon constructionism in learning theory rather than behavioral or cognitive learning theory such as ADDIE. Hence, DT ISD model is an effective instructional design model for adult lifelong education program. It is suggested that action research is necessary to examine the external validation of DT ISD model.

The purpose of this study was to shed light on a role of hope in understanding the relationship between the search for meaning in life and academic satisfaction and to suggest ways to increase hope among Korean students. We hypothesized that the relationship between search for meaning in life and academic satisfaction would be mediated by hope and the positive relationship between search for meaning and hope would be strengthened by family support and friend support. We conducted two surveys to examine the hypotheses. Based on Study 1 using a sample of 190 undergraduate students, we found that the relationship between search for meaning in life and academic satisfaction was fully mediated by hope. In Study 2, we examined the four types of hope that include internal hope and three types of external hope (i.e., family, friends, and supernatural being) to extend knowledge on what features of hope mediate the relationships between search for meaning and academic satisfaction. Study 2 based on a sample of 313 high school students showed that the link from the search for meaning in life and academic satisfaction was fully mediated by internal hope and external-peers hope. The mediating effects of external-family hope and external-spiritual hope were not significant in Study 2. Also, we found that family support strengthened the positive links from the search for meaning in life to hope (Study 1) and to internal hope (Study 2) while the interactive effects of friend support and the search for meaning on hope were not significant in both studies. Based on the results, we discussed several implications, limitations, and recommendations for future research.

The study examined the mental representation of children in foster care through the MacArthur Story Stem Battery (MSSB) and reviewed difference between children in foster care and typical children in terms of mental representation. Subjects of the study included a total of 50 children: 25 children (11 boys and 14 girls), aged from 5 to 8, in foster care in Gyeonggi Province, and 25 typical children (11 boys and 14 girls), aged from 5 to 8, who lived in Seoul and Gyeonggi Province. The research findings are summarized as follows: First, in terms of mental representation, children in foster care showed less subjects of empathic relations and more subjects of disorganized aggression than typical children. Second, children in foster care showed lower coherence mental representation than typical children. Finally, children in foster care were more likely to fail in emotional regulation than typical children in mental representation.
