Given the importance of early experience in algebraic thinking, we designed six consecutive lessons in which $4^{th}$ graders were encouraged to recognize patterns in the process of finding the relationships between two quantities and to represent a given problem with various mathematical models. The results showed that students were able to recognize patterns through concrete activities with manipulative materials and employ various mathematical models to represent a given problem situation. While students were able to represent a problem situation with algebraic expressions, they had difficulties in using the equal sign and letters for the unknown value while they attempted to generalize a pattern. This paper concludes with some implications on how to connect algebraic thinking with students' arithmetic or informal thinking in a meaningful way, and how to approach algebra at the elementary school level.

With the development of digital technology related to mobile, cloud, IoT, even traditional businesses have began to develop strategies for digital transformation. This is regarded as a very important part for business sustainability. However, many of these attempts are being conducted from the management point of view, and there has been little research on user experience design for digital transformation. In this study, Starbucks, which started a offline store business and expanded its experience with online services, was selected as a representative case and user research was conducted on it. Through an usability evaluation and post-task interviews of the Starbucks mobile application users, we discovered important issues of user experience to consider when transforming and expanding services online from offline. Based on the findings, the considersations for designing online user experience were discussed and proposed. These are expected to contribute to the process of researching and implementing digital transformation.

This study is a descriptive study to investigate the relationship between verbal violence type, emotional response and coping in the operating room nurse. The subjects of the study were 400 nurses working in 20 general hospitals and 372 nurses in the operating room. As a result of the analysis, it was found that the perpetrators of the verbal violence experienced by the subject were physicians, direct supervisors, and more than half of the subjects were considering the transition. The most frequent cases of language violence were when the equipment was inoperable or not used during surgery, There were significant differences in verbal violence experience according to marriage, clinical career, and work style. Language violence emotional response showed significant difference with gender, position and coping, age, academic background, clinical career, and position. There was a significant correlation between experience of verbal violence and emotional response, emotional response and coping. Therefore, the results of this study will contribute to the development of coping strategies and prevention education programs.

The purpose of this study was to examine the influential factors on parenting guilt of mothers who use a day-care center. To achieve these research goals, the present study 1) analysed the differences in the mother's parenting guilt as the socio-demographic variables of the mother and child, and 2) examined the relative effect size of influences on the mother's parenting guilt with their parenting efficacy, satisfaction on the day-care center, emotional and informational support from teachers, and mother's active interaction with day-care teachers. The participants of the study were 350 mothers whose infants and toddlers were attending day-care centers in Gwangju and Jeollanamdo. The results of this study are as follows. First, the mothers with infants who were younger than 3 years old reported more parenting guilt than the mothers with toddlers. Second, the mothers whose children were the first child reported more parenting guilt than the mothers with children who were the second or the third child. Third, the emotional support from the day-care teacher was the most influential factor on the mother's parenting guilt. This study suggests that the mutual cooperation between mother and day-care teacher are very important to reduce the mother's parenting guilt.

This study aims to explore the realities of life and the utilizing experience of housing improvement service among the vulnerable living in the indecent house. For this purpose of this study, we conducted in-depth interview with nine interviewees. As the result of this study, we figured out that the vulnerable living in the poor house had experienced psychological withdrawals, restricted of social activities, health problems, and feelings of insecurity. However, they could not afford to improve their houses because they were living below or near the poverty line. Local government provided the housing improvement service to cope with this problem. The people received this service gave positive reviews. Since their residential environment was improved, they felt easiness, strengthened social relationships, and expected a warm winter. Despite of 'thankful service', the housing improvement service had some limitations. Because of the limited budgets, full-scale construction services were unfeasible. Also we figured out it is necessary to make a change in housing policies for the people living in the poor houses. In the conclusion, we discussed and proposed the policies and practical suggestions.

The image of science is one of the recurrent topics in science education research. In particular, we believe that students' images of Doing-Science-Well could be used for identifying not only students' perceived goals of science learning, but also practical guidelines of effective science teaching. In this study, the students' images of Doing-Science-Well were investigated with the following two research questions: (i) what are student's images of Doing-Science-Well?; (ii) in what contexts do students perceive that someone is doing science well? Thirty seven students in a high school in Seoul, Korea were asked to write their personal experiences by which they realized that someone was doing science well. The main results of the study are the following: Firstly, the images of Doing-Science-Well could be categorized into 'Einstein type', 'Socrates type', 'MacGyver type' and six more types. Secondly, with regard to contexts, students tended to realize that somebody is doing science well in terms of two kinds of contexts: 4 physical contexts and 6 psychological contexts. The findings led us to develop a frame of judging Doing-Science-Well, which combines the types and two kinds of contexts. The frame illustrates the multiplicity of the images of Doing-Science-Well.

With the development of the Internet, users share their experiences and opinions. Since related keywords are used witho0ut considering information such as the general emotion or genre of an unstructured document such as a movie review, the sensitivity accuracy according to the appropriate emotional situation is impaired. Therefore, we propose a system that predicts emotions based on information such as the genre to which the unstructured document created by users belongs or overall emotions. First, representative keyword related to emotion sets such as Joy, Anger, Fear, and Sadness are extracted from the unstructured document, and the normalized weights of the emotional feature words and information of the unstructured document are trained in a system that combines CNN and LSTM as a training set. Finally, by testing the refined words extracted through movie information, morpheme analyzer and n-gram, emoticons, and emojis, it was shown that the accuracy of emotion prediction using emotions and F-measure were improved. The proposed prediction system can predict sentiment appropriately according to the situation by avoiding the error of judging negative due to the use of sad words in sad movies and scary words in horror movies.
