The purpose of this study is to identify the differences of argumentation discourses for Socio-Scientific Issues in the types of decision-making and personality traits of pre-service biology teachers. For this study, SSI discussion topics were selected according to four types of decision making: logical reasoning, suggestion of complement, emotional base, and internal conflict. Three groups were constructed based on personality traits such as extroversion, acceptability, and integrity. Each three group used the workbook specially developed and freely used the smart device for discussion. A recorder and a camcorder were used to record each group, their behavior was recorded and the written materials during the discussion were collected for the results. Using Walton's analysis framework, the collected data analyzed in terms of the source of utterance, the process of dialogue shift, and the critical movements that can judge the reasoning of utterance. As a result of the study, it was confirmed that the decision-making type of SSI topics and learners' personalities were influential in the decision-making process of SSI small group discussions. This research shows that there is a need to develop instructional materials considering decision-making types and learners' personality types of students as well as pre-service teachers for SSI discussion.
This study aims to identify a new direction in the consumer-brand relationship by quantitatively approaching from the psychological aspect consumers' brand love, which is the most powerful strategic element in forming an emotional consumer-brand relationship. What significance does brand love have in a consumer-brand relationship? Brand love is the most fundamental in the emotional consumer-brand relationship. Through brand ownership, consumers add meaning to their lives, and love brands by expressing themselves. Love is a scale that understands consumer-brand relationship from the most interpersonal aspect and can be considered as the most essential element in an empathetic relationship. Consumers' brand love not only determines brand image and reliability but through brand loyalty, it also influences market competitiveness. In addition, as a medium that can overcome brand crisis, it serves as a turning point of the relationship and can enhance the strength of consumers' brand love. Under such generational and theoretical background, this study took a psychological approach on love in emotional consumer-brand relationship. Focusing on the most representative theory and classification of love, Sternberg's Triangular Theory of Love, types of brand love were examined. 552 questionnaires were distributed through a survey with mobile phone service and product brands, and a factor analysis was conducted. Types of brand love revealed through the results of this study were very similar to Sternberg's types of love, and it was found that the types of brand love varied based on product category. It can be suggested that the concept of brand love is an important strategic idea in brand communication.

For this, this study placed focus on the essential aspects of the experience of using the service including the meaning of the choice of users being emphasized as practical principles in user-centered services as well as the real context of such a choice. The research methods suggested by Giorgi in phenomenological studies were adopted for data analysis, and intensive interviews were conducted for 10 users living in Seoul who are over 65 years of age. According to the results of the analysis, the interviewees' experience of the service as users were categorized into the elements of "restricted choice of service", "unstrengthened right for the users", "ambivalent emotion about the service", and "awareness of the importance of the relationship with the caregiver", and the essential phenomenon in their experience of the service was "the importance of relationship within restricted choice". This study found out that the choice or self-determination of users was still restricted in the usage of user-centered services. It also found out that the users think it more important to have a positive relationship with the caregiver than the choice of the service granted to them. On the basis of such research results, political implications are proposed to help the establishment of user-centered services.

Sales representatives of automobile company play a key role in the circulation system. Given the characteristics of the good, consumers demand high-quality information and guides from the salespersons when they decide to purchase an automobile. Sales representatives provide service to the customers in accordance with their needs to help purchase decision-making process. Therefore, a sales representative's personal competence have a significant effect on sales performance. Based on this hypothesis, we assumed that personal competence of a salesperson has a positive correlation with sales performance. An empirical analysis was conducted to test the hypothesis. This study classifies personal competence into 4 independent variables((1) sales technique professionalism (2) salesperson's attitude and relationship with customers (3) emotion utilization (4) emotion control) and measures the correlation with the dependent variable(sales performance). To verify the relationship, we set and modified the hypothesis based on the precedent studies and researches. In addiction, a survey was conducted targeting 300 local salespersons from Gyeonggi-Gangwon region. 268 valid samples were used and analyzed with SPSS WIN24.0 statistical program. As a result of an empirical analysis, it turned out that sales technique professionalism and emotion utilization have positive correlation with sales performance. However, the result failed to support the assumption that sales representative's attitude and relationship with customers and emotion control have positive correlation with sales performance. At last the result revealed that personal competence should be considered as an important determinant of recruitment specification for sales representatives.
As the number of students in the multicultural background grows, the interest in their education is also increasing. The purpose of this study is to investigate the effect of forest healing factors on the improvement of language ability and ego-resilience of students from multicultural families. We conducted an after-school forest healing program of ten male and ten female middle school students of a multicultural preparatory school located in ${\bigcirc}{\bigcirc}$-dong in Cheongju, Chungnam Province. The experiment consisted of a total of 12 weekly one-hour (60 minutes) programs from April 12, 2018 to June 26, 2018. The forest healing program is an activity that uses the various environmental factors that exist in the forest to increase the immunity of the human body and restore physical and mental health. To determine the difference in ego-resilience before and after the program, we conducted a paired t-test and analyzed with the SPSS 18.0 program. The results showed that the ego-resilience significantly improved in all sub-factors including the positive thinking ability, problem-solving ability, intimacy ability, emotional adjustment ability, and autonomic behavior ability (p<.001). The descriptive statistics of the language ability showed the improvement in writing errors, pronunciation errors, sentence errors, tense errors, and errors in research and connection. We expect the results of this study can be used as the basic data to improve ego-resilience and language acquisition ability of middle-entry children and students from multicultural families.
The human voice is one of the easiest methods for the information transmission between human beings. The characteristics of voice can vary from person to person and include the speed of speech, the form and function of the vocal organ, the pitch tone, speech habits, and gender. The human voice is a key element of human communication. In the days of the Fourth Industrial Revolution, voices are also a major means of communication between humans and humans, between humans and machines, machines and machines. And for that reason, people are trying to communicate their intentions to others clearly. And in the process, it contains various additional information along with the linguistic information. The Information such as emotional status, health status, part of trust, presence of a lie, change due to drinking, etc. These linguistic and non-linguistic information can be used as a device for evaluating the individual's credit worthiness by appearing in various parameters through voice analysis. Especially, it can be obtained by analyzing the relationship between the characteristics of the fundamental frequency(basic tonality) of the vocal cords, and the characteristics of the resonance frequency of the vocal track.In the previous research, the necessity of various methods of credit evaluation and the characteristic change of the voice according to the change of credit status were studied. In this study, we propose a personal credit discriminator by machine learning through parameters extracted through voice.
In December 2012, a pile driving boat sunk off the coast of Ulsan port in Korea. The cause of capsizing of these boats was considered a complex problem. Although Korean Ship Safety Technology Authority concluded that leaders (cranes) of the vessel were designed with sufficient safety factors, National Forensic Service concluded that the capsizing was caused by the failure of leaders. This study reviewed the related laws, strength calculations, and structural analysis methods used by the Korea Ship Safety Technology Authority. In addition, numerical simulations were carried out on hydrodynamic analysis and structural analysis to analyze the cause of vessel capsizing based on the rules of the Korean Register of Shipping. The results were similar to those found by National Forensic Service. In conclusion, the study suggested that inspection especially for a pile driving boat subjected to the Korean Register of Shipping rules should be carried out to prevent the similar accident.
