This study explored the possibility of psychological testing as a way to proactively support underachieving students. Among the four-year college students that participated in our study, 43 students who participated in the academic warning support program for the second semester of 2019 and 30 students who had no academic warning experience used the data from the study personality type test. For data analysis, technical statistics, t-test, and correlation analysis were performed using jambi 1.1.9.0 to obtain the Pearson correlation. Studies have shown that the two classes of students differ in their learning behavior patterns. A student with a bachelor's degree warning scored high in the rest of the class, except for rebelliousness, perfection, mixed thoughts, hard work, satisfaction, single-mindedness and type satisfaction. This can be seen as a factor in the psychological conflict, such as the discrepancy between what one likes and what one studies, and lack of available support. It has been confirmed that psychology, emotional parts and economic support are needed as well as learning skills. In addition, this study is expected to provide basic data for proper preemptive support in schools, such as the prevention of dropouts and counseling programs.

This study has its purpose of researching on the relevant variables which affect the attitude toward engineering science and brain dominance for the department of engineering students. The results of this study are as follows: First, the department of engineering students' attitude toward engineering science has shown the order of cognitive element (3.73), definitional element (3.05) and behavioral element (2.86), and in the actual context it is considered that it is necessary to establish a teaching-learning strategy which can reinforce the behavioral elements such as experiments and practices as well as can improve engineering-related cognitive ability. Second, the attitudes toward engineering science according to their brain dominance thinking (Type A: analyst, Type B: Administrator, Type C: Cooperator, and Type D: Jointer) have no significant difference, but the students of Type A who have the characteristics of 7 analyzing thinking have shown high academic accomplishment. Based on these results of study, it is necessary to make a change of the current teaching-learning stratery in accordance with the types of thinking of the students from the teaching-learning perspective. In particular, in order to develop the weak dominance properties and thinking type of individual learners, the change in teacher's recognition that the teacher's teaching-learning strategy and practice is important has to take precedence.

사람에게 행동의 개인차가 있듯이 rat이나 mouse에 있어서도 행동의 차이를 발견할 수 있다. Rat의 행동성향에 따른 (1)학습 및 기억 능력의 차이, (2)기억과 해마의 관계, (3)치매유발단백질의 하나로 알려진 아밀로이드 베타($A{\beta}$ )및 수종의 항 치매 약물효과를 알아보는 것이 본 실험의 목적이다. Rat의 행동관찰을 통해 두 가지 행동패턴을 관찰할 수 있었는데, 이러한 rat의 행동 특성은 심리학자 Jung이 심리유형으로 설명하고 있는 extraversion, introversion의 행동성향과 유사할 것이라는 가정 하에 실험을 계획, 실시하였다. Rat에 water maze test를 실시하여 공간 기억의 단기, 장기 기억을 분석하였는데 그 결과 두 가지 행동 성향을 가진 rat은 서로 다른 학습 및 기억 능력의 특성을 보였다. 즉, extraversion은 단기 기억의 향상을 보인 반면에, introversion은 장기 기억의 향상을 보였다. Rat을 대상으로 water maze test 외에 Y-maze, passive avoidance test를 실시하여 공간 기억(spatial memory), 작동 기억(working memory), passive avoidance memory, 그리고 단기, 장기 기억의 관계를 종합적으로 분석해 보았다. 그 결과 두 가지 행동성향에 따라 서로 영향을 미치는 기억의 종류 및 관계에 차이가 있음을 발견할 수 있었다. 또한 두 가지 행동성향을 가진 rat에 약물을 투여했을 때, 서로 다른 약물 효과를 보였으며, $A{\beta}$ 를 주입했을 때, 기억(memory) 및 해마(hippocampus) 세포 사멸(cell death)에 서로 상반된 결과를 보여주었다. 이러한 연구 결과는 개체의 행동성향에 따라 학습 및 기억의 효과가 다를 수 있음을 보여주는 결과라 할 수 있고, 개인의 적성과 소질의 인식 및 개발의 중요성에 시사하는 바가 크다. 또한 개개인의 행동과 학습 및 기억 능력의 차이를 두뇌과학적으로 이해하여, 두뇌의 장점은 살리고 단점을 보완할 수 있는 이론적 토대를 세우는데 이러한 동물실험이 그 기초를 제공해 줄 수 있을 것이다. 또한 행동성향 및 기억의 종류에 따른 약물효과의 차이는 기억과 관련된 질병인 알츠하이머 환자에 있어 개개인에게 맞는 적절한 특징적인 치료약물이 존재할 것이라는 가능성을 제공해줄 뿐만 아니라 학습과 기억력 증진 효과를 기대해 볼 수 있을 것이라고 생각된다.

In this paper, we propose an intelligent model lot extraction of the web user's preference and present the results of evaluation. For this purpose, we analyze shortcomings of current information retrieval engine being used and reflect preference weights on learner. As it doesn't depend on frequency of each word but intelligently learns patterns of user behavior, the mechanism Provides the appropriate set of results about user's questions. Then, we propose the concept of preference trend and its considerations and present an algorithm for extracting preference with examples. Also, we design an intelligent model for extraction of behavior patterns and propose HTML index and process of intelligent learning for preference decision. Finally, we validate the proposed model by comparing estimated results(after applying the Preference) of document ranking measurement.

According to the online learning environment, learning activities using mobile technology have emerged as a major concern. The features of mobile technology show potential supporting the emergence of learners' agencies in science education. In this study, 22 research literature on mobile activities in science teaching and learning published in Korea from 2011 to April 2020 were selected. First, the framework of Suarez et al. (2018) was revised and the types of mobile activities were categorized and investigated. Second, the emergence of agencies was examined in the context of science teaching and learning. And also, the relevance of mobile activity types ('Access to content', 'Data collection', 'Peer-to-peer communication', 'Contextual support') to support learners' agency dimension ('goals', 'content', 'action', 'strategy', 'reflection', 'monitoring') was analyzed. The first analysis show that science teaching and learning through mobile activities are changing from traditional to student-centered. Through these activities, students become more involved in learning and get the opportunity to become agents of learning. As a result of the second analysis, it has been confirmed that the emergence of learners' agencies has been supported and strengthened through mobile activities. Whereas, it needs to look upon the relationship between learners' agency and mobile activities in the overall context of science class. This consideration led to implications for the use of mobile technology in future science education and the transition to student-centered education.

The purpose of this study is to analyze errors and treatment behavior during the course of mathematics learning of academic achievement by applying reflective activities in the second semester of the third year of elementary school. The study participants are students from two classes, 21 from the third-grade S elementary school in Seoul and 20 from the comparative class. In the case of the experiment group, the multiplication unit was reconstructed into a mathematics class that applied reflective activities. They were pre-post-test to examine the changes in students' mathematics performance, and mathematical communication was recorded and analyzed for the focus group to analyze the patterns of learners' error handling in the reflective activities. In addition, they recorded and analyzed students' activities and conversations for error type and error handling. As a result of the study, the student's mathematics achievement was increased using reflective activities. When learning double digit multiplication, the error types varied. It was also confirmed that the reflective activities helped learners reflect on the multiplication algorithm and analyze the error-ridden calculations to reflect on and deal with their errors.

The purpose of this study was to explore the elements of teaching behavior and classify instructional types through the teacher's classroom observation in elementary school science classrooms. 18 elementary school teachers were selected at Seoul city and Kyungkido. The topic of lesson was 'How the weight of object is changed according to the shape to sink in the water'. Each class was recorded and analyzed that. The teaching behavior elements were used inductional analysis method. The instruction types were classified into instructional organization, teaching strategies in teaching-learning processes, the level of openness of inquiry at science classroom. The validity and reliability of the data were analyzed by 7 science educators. The results of the analysis of the teachers discourse showed that there are 23 types of teaching behavior elements. Used teaching behavior elements revealed the differences from each teacher. There were 7 types among the 12 types of class and the most common types of instruction were unsystematic, teacher-centered, and guided-inquiry. The result showed that guided inquiry type was found more than open inquiry type and teacher-centered instructional, content-centered instructional, superficial inquiry process showed characteristic.

The conduct of seafarer is major cause of marine accidents. This study models the behavior of the seafarer based on the Hidden Markov Model (HMM). Additionally, through the path analysis of the behavior estimated by the model, the kind of situations, procedures and errors that may have caused the marine accidents were interpreted. To successfully implement the model, the seafarer behaviors were observed by means of the summarized verdict reports issued by the Korean Maritime Safety Tribunal, and the observed results converted into behavior data suitable for HMM learning through the behavior classification framework based on the SRKBB (Skill-, Rule-, and Knowledge-Based Behavior). As a result of modeling the seafarer behaviors by the type of vessels, it was established that there was a difference between the models, and the possibility of identifying the preferred path of the seafarer behaviors. Through these results, it is expected that the model implementation technique proposed in this study can be applied to the prediction of the behavior of the seafarer as well as contribute to the prioritization of the behavior correction among seafarers, which is necessary for the prevention of marine accidents.
