The purpose of this research was to investigate the change of argumentation of middle school students when they participated in argument tasks with CASE(Cognitive acceleration through science education) programs. Students argumentations were divided into two categories; 'explanatory argumentation' and 'dialogic argumentation'. Several argumentation components were used in their argumentation. Among argumentation components, claim and ground took place more than half of argumentation components. The percentage of 'dialogic argumentation' was lower than the percentage of 'explanatory argumentation'. The percentage of 'dialogic argumentation' was getting higher during CASE intervention. CASE programs had more effect on symmetric group than asymmetric group, however it was unstable. In general, participation ratio in argumentation of the formal operational student was high and the ratio in argumentation of the transitional student was getting higher.

The STEAM education was applied to science high school students, and changes in perceptions of students and teachers were investigated after class treatment. By the results of the student's perception survey, very positive results were found in increasing problem-solving capabilities, educational satisfaction, etc. More than 98% of students said they would continue to participate in STEAM education classes. Meanwhile, the lack of time for class activities put a burden on students to complete the problems during class. Especially nanoscience content and activities were properly organized in consideration of the level of cognitive development of the students. In addition, as a result of a survey of teachers' perceptions for students, more than 80.0% of teachers responded very positively in 'self-directed learning ability' and 'problem-solving capability', etc.

정보통신기술의 발달로 사내 주요 정보들이 보다 쉽고 다양한 경로로 외부로 유출이 가능해짐에 따라 산업 기술 유출로 인한 보안사고가 증가하고 있다. 이러한 보안사고는 문서 유출 경로에 따라 악의적인 공격자가 외부에서 침입하여 유출된 경우와 내부정보 접근이 용이한 인력(전 현직 임직원 및 협력업체 직원)에 의해 유출된 경우로 크게 2가지 형태로 분류될 수 있으며, 유출된 사내 주요 정보들은 기업의 막대한 피해를 가져오게 된다. 기업 측면에서도 사내 보안 관리는 더 이상 선택이 아닌 기업의 생존을 위한 필수 요소임을 인지해야 하며 기업의 보안 관리 수준의 향상이 필요하다. 따라서 본 연구에서는 필수적인 사내 보안 관리 방안의 가이드라인을 제시함으로써 기업의 사내 보안 수준을 향상시키고자 한다.

As the 3D modeling technology and conversational algorithm is developed, digital humans are being used in various fields, and also virtual bankers have begun to appear in banks, including major banks such as Shin-Han Bank and Nong-Hyup Bank. However, most of the research of digital human mainly focus on its appearance, and research on robot persona that should be considered in anthropomorphizing a robot is insufficient. In this study, an experiment was conducted to find out the user experience of three scenarios (student ID receipt, deposit and withdrawal account opening, leasehold loan consultation) in which the level of anthropomorphism of the speech strategy and the level of personal information use differed in the specific context of banking. As a result of the study, social presence and usefulness had an interactive effect on the scenario and the level of anthropomorphism. There was no interaction effect on intimacy, trustworthiness, and perceived intelligence, but a tendency could be confirmed.

This paper is based on the effects of Zone of Proximal Development and scaffolding theory of social constructivist, Russian psychologist Vygotsky. He insisted that a social interaction play a fundamental role in the development of cognition. This study is to examine the efficient of the scaffolding types in Math class. The ZPD is the distance between a student's ability to perform a task under adult guidances or with peer collaboration and the student's ability solving the problem independently. To conduct the research was grouped into an experimental first grader five students in H high school in Y county. After class, students were questioned through Semi-structured interviews. The results of this study are below. First, Students were satisfied with the class mixed micro-scaffolding types and Macro-scaffolding types and improved their math thinking ability and the ways of solving problems. Second, The results of the class showed that students' ability to perform a task was transferred to the higher level through the help of a teacher or peers. Students could have more time to listen to peers' opinions and to say their own thoughts freely than they were under the lecture method instruction. Third, Students were interested in math through the experimental class. That's because the appropriate help of the scaffolding type, a cooperate study, relative with real life, using an engineering tools. They made a change of perception.

The purpose of this study was to explore how primary school students develop their interest in science. A survey questionnaire was used to investigate students' interest, change of their interest, and engagement in science related activities three times a year. 201 students of two primary schools in Seoul Metropolitan City initially participated in this study. A follow-up case study was conducted with students who showed an increased interest in science. Finally, seven students were chosen in the case study. They were asked to keep a photo journal for 12 weeks, and were interviewed in every other week by one of the researchers. Among these seven participants, two (TK and QQ) were chosen for analyzing their data in this case study because they showed positive changes in developing science interest throughout the study. The results of two participants' survey, photo-journal and interview were analyzed qualitatively. First, TK, whose science interest developed from situational interest II to individual interest I, engaged in doing experiments at home, doing mathematics activities, raising pets or plants, observing phenomena, and visiting informal educational centers. He tended to participate in hands-on activities by himself in out-of-school settings. Second, QQ who developed from situational interest I to situational interest II, engaged in taking pictures as a representative activity at home and school. He tended to participate in activities with either his father or one of the researchers. Both students showed personal characteristics such as doing place-based activities, interaction with others and activity subjectivity. The goal of TK's interactions with others on the various places was to develop in cognitive domain. On the contrary, QQ's goal of interactions with others was to develop in emotional communication. This study reported the cases of characteristics of students who developed their interests in science including activities in- and out-of-school settings and their accompanying people.

This study was conducted to compare the self-leadership strategies and self-efficacy among the four types of career development in the Korean engineering college students. When the two variables including career decision level and career preparation behavior were considered, four different types of career development were obtained: immature, behavioral, pseudo, and ideal type. The results showed that the ideal type obtained the significantly higher scores on the self-leadership and self-efficacy scales than the other three types. The results of stepwise analysis suggested that each subtype had unique characteristics in relation to self-leadership strategies. Therefore, it would be useful to provide the engineering students with the specialized self-leadership training program based on the types of career development.

For the purpose of better understanding of RAD children, comparisons were performed about the developmental and psychopathological characteristics between RAD and PDD children. Study subjects were the children between the ages 2 and 6. who visitied SNUCH Child and Adolescent Psychiatry OPD or treated in Day Treatment Center during May, 1989 and Sep., 1991, diagnosed by the child psychiatrist as RAD or PDD according to DSM-III-R diagnostic criteria. A total of 40 children were included in the study. 20 were RAD(18 boys, 2 girls). 20 were PDD(20 boys). PEP was performed to all study subjects, by the raters blind to psychiatric diagnosis of each. And analysis was done about the level of developmental functioning score and psychopathological scores between RAD and PDD children. The results are as follows 'There were retardation on the general developmental functioning in RAD children, and the severity of retardation were lined up as perceptual ability>imitation>gross motor>cogitive language>eye-hand coordination>fine motor. Characteristics of psychopathology in RAD children were lined up by severity as language>play>relationship>affection >sensory. Group differences of the two shows on PDD group rejection score was significantly higher on the perception item. while RAD was superior on the perception emerging response. Differences of the psychopathology between two groups were on such areas as ; Affection, which was significantly higher on 'Absent' in RAD, while significantly higher on 'severe' in PDD children. On the interest for the play and materials. sensory and language areas, RAD children were significantly higher ratings on 'Absent' than PDD children.
