The purpose of this study is to investigate elementary students' communication in process of applying mathematical modeling. For this study, 22 fifth graders in an elementary school were observed by applying mathematical modeling process (presentation of problem ${\rightarrow}$ model inducement activity ${\rightarrow}$ model exploration activity ${\rightarrow}$ model application activity). And the level of their communication with their activity sheets and outputs, observation records and interviews were also analyzed. Additionally, by analyzing the activity cases of and , this study researched that what is a positive influence on students' communication skills. Whereas showed significant advance in the level of communication, who communicated actively on speaking area but not on every areas showed insensible changes. To improve communication abilities, cognitive tension and debate situation are needed. This means, mathematical education should continuously provide students with mathematical communication learning, and a class which contains mathematical communication experiences (such as mathematical modeling) will be needed.

This study examined the longitudinal effects of appearance satisfaction and Korean language skills on the self-esteem and school adjustment of multicultural adolescents. The study used data from 1,151 multicultural adolescents from the $3^{rd}$, $4^{th}$, and $5^{th}$ waves of the Multicultural Adolescents Panel Study (MAPS). Data were analyzed by means of descriptive statistics, Cronbach's alpha, correlation, and structural equation modeling. The results are as follows. First, appearance satisfaction and Korean language skills at grade 6 significantly predicted higher self-esteem at grade 7. Second, there was a significant influence of high levels of self-esteem at grade 7 on positive school adjustment of grade 8. Last, the self-esteem at grade 7 had a significant mediating effect in the relationship between appearance satisfaction and Korean language skills at grade 6 and school adjustment at grade 8. The results of this study highlighted the importance of self-esteem as a mediating factor in the connection between appearance satisfaction and Korean language skills as well as the level of school adjustment. This provides supporting evidence to many educators and parents for the implementation of effective support practices for multicultural adolescents to enhance their school adjustment. Other related implications of these findings and suggestions for future research are also discussed.

A common language for modelling software requirements and design in recent years is Unified Modeling Language (UML). Essential principles and rules are provided by UML to help visualize and comprehend complex software systems. It has therefore been incorporated into the curriculum for software engineering courses at several institutions all around the world. However, it is commonly recognized that UML is challenging for beginners to understand, mostly owing to its complexity and ill-defined nature. It is unavoidable that we need to comprehend their preferences and issues considerably better than we do presently in order to approach the problem of teaching UML to beginner students in an acceptable manner. This paper offers a hint based approach that can be implemented along with an ordinary lab task. Some keywords are heighted to indicate class diagram component and make students to understand the textual descriptions. The experimental results indicate significant improvement in students learning skills. Furthermore, majority of students also positively responded to the survey conducted in the end experimental study.

Simulation technology is a type of shipbuilding product lifecycle management solution used to support production planning or decision-making. Normally, most shipbuilding processes are consisted of job shop production, and the modeling and simulation require professional skills and experience on shipbuilding. For these reasons, many shipbuilding companies have difficulties adapting simulation systems, regardless of the necessity for the technology. In this paper, the data model for shipyard production simulation model generation was defined by analyzing the iterative simulation modeling procedure. The shipyard production simulation data model defined in this study contains the information necessary for the conventional simulation modeling procedure and can serve as a basis for simulation model generation. The efficacy of the developed system was validated by applying it to the simulation model generation of the panel block production line. By implementing the initial simulation model generation process, which was performed in the past with a simulation modeler, the proposed system substantially reduced the modeling time. In addition, by reducing the difficulties posed by different modeler-dependent generation methods, the proposed system makes the standardization of the simulation model quality possible.

본 연구에서는 보육교사가 일과 중에 학급 유아를 대상으로 실행하는 정서적 지원 수준이 유아의 인성에 미치는 영향을 살펴보고자, 위계적 선형모형을 사용하여 교사의 정서적 지원 및 유아 개인의 성과 월령, 교사의 학력과 경력, 그리고 학급의 교사 대 유아 비율 및 기관설립유형이 유아의 인성 특성인 자기통제, 주장성, 협력성 및 책임성에 미치는 영향력을 분석하였다. 연구대상은 만5세 유아 646명과 이들의 담임교사 32명, 주양육자 555명으로, HLM 7.0을 이용하여 수집된 자료를 분석하였다. 연구 결과 교사가 보고한 유아의 자기통제, 주장성 및 협력성은 학급 간 차이가 있었으나, 부모가 보고한 자기통제, 주장성, 협력성 및 책임성은 학급 간 차이가 없었다. 또한 남아보다 여아가, 월령이 높을수록 유아의 인성 특성의 수준이 높은 것으로 나타났으나, 교사의 정서적 지원뿐만 아니라 학력, 경력 및 교사 대 유아 비율과 기관설립유형은 학급 간 차이를 예측하지 못하였다. 그러나 학급 수준의 예측변인 투입 이후에도 교사가 지각한 유아의 인성 특성에서 여전히 학급 간 차이가 존재하는 것으로 밝혀져, 추후 연구에서는 인성 특성의 학급 간 차이에 영향을 미치는 예측변인을 추가적으로 탐색하는 것이 요구됨을 시사하였다.

This study aimed to analyze the subjects, situations, and reflection levels related to role modeling experienced by medical students during their clinical clerkship and their own reflections. This study intends to suggest ways of improving how residents and clinical faculty should treat and teach medical students. Written interviews were conducted regarding senior medical students' role modeling experiences during their clinical clerkships in 2018 and 2019. Content analysis was conducted for a total of 224 cases from 196 students. Content analysis revealed three types of role modeling content: subjects (faculty, residents, nurses, peer students), situations (clinical competence, personal qualities, teaching skills), and the level of reflection (critical reflection, reflection, thoughtful action, and habitual action) in each case. As role model subjects, faculty were found to be the paramount role model (n=142, 62.83%). Role modeling was the most frequently performed for clinical competence (n=103, 45.98%). Clinical competence was frequently shown in communication and empathic listening during rounds and outpatient relationships between the patient and doctor. Regarding the level of reflection for role modeling, the number of critical reflections was 86 (38.39%) and that of reflections was 80 (35.71%). In particular, negative role modeling showed a high level of critical reflection in relation to faculty (64.44%) and nurses (8.89%). In conclusion, role modeling of medical students participating in clinical clerkships occurs in situations that the role models are not aware of, with positive or negative effects on the formation of professional identity among medical students.
