무선 센서 네트워크는 센서노드와 싱크로 구성되며, 센서 노드로부터 생성된 신호들은 싱크로 전송되어 처리된다. 센서네트워크는 모든 노드들이 한정된 에너지를 가지고 운용되기 때문에 센서 네트워크를 오랫동안 유지하기 위한 연구가 많이 진행되어 왔다. 대부분의 연구들은 싱크를 고정으로 가정하였다. 그러나 실제 환경에서는 사람이나 자동차등에 의해 싱크가 이동성을 가지는 경우가 많다. 본 논문에서는 이동 싱크에 기반한 그리드 방식을 적용하여 노드의 에너지 소비를 줄이기 위한 방안을 제안한다. 이 방안은 대부분의 라우팅 작업량을 이동 싱크가 처리하고, 무선 센서지역을 세분화하여 운용함으로써 전력 소비를 줄인다. 또한 시뮬레이션에 의한 성능 평가를 통해 제안방안에 대해 분석하였다. Wireless Sensor Network consists of sensor nodes and sink. A sink receives and processes signals created from sensor nodes. Many studies have been performed, since sensor network allows multiple nodes to run using a limited amount of energy, Most researches have focused on using fixed sink. However, in many cases, the sink has mobility effected by man, cars, and etc. This research proposes three methods for reducing the node's energy consumption which is applied the Grid method based on mobile sink. Most routing processes handled by the mobile sink and wireless sensor area is separated and operated respectively. So, this research allows decreasing the power costs. In addition, it also proposes methods using simulation to test the quality of the performance.

The purpose of this study was to identify the impact of attachment styles on social competence mediated by emotional regulation among young children. The subjects of this study were 283 mothers who had three to five year old children and it was drawn from four kindergartens located in Cheongju, Chungju, and Jecheon. Data were analyzed by factor analysis and Cronbach's α with SPSS Win program. Additionally, the theoretical model was specified and estimated based on previous literature. The model was tested through the analysis of correlation matrix in LISREL VIII package using maximum likelihood estimation. The findings of the study were as follows: 1) Young children's secure attachment style directly varied their social competence which was categorized into four dimensions including leadership, reciprocity, non-cooperation, and avoidance. The study result showed that young children with secure attachment was more likely to perform leadership in their peer relationship, and to show positive reciprocity in their interaction with peers and teachers. 2) Young children's secure attachment style, mediated by internal and external regulation of emotion, indirectly predicted their social competence. Specifically, leadership and reciprocity of social competence were indirectly explained. 3) Unlike secure attachment style, young children's insecure attachment style did not have a direct effect on their social competence. The result indicated that insecure attachment style did not explain any type of young children's social competence. 4) Despite the outcome in relation to the direct relationship between insecure attachment style and social competence, insecure relationship indirectly predicted their social competence through a mediating effect of external regulation of emotion. Insecure attachment made a young child to be not cooperative by causing difficulties in external regulation of emotion. 5) As well as external regulation, internal regulation of emotion also mediated the relationship between insecure attachment and social competence among young children. Young children's insecure attachment style increased the degree of their non-cooperation and avoidance by deteriorating ability of internal regulation of emotion.

This study sought to understand how the distance learning of social studies has been conducted during the COVID-19 pandemic. To this end, from April to October 2020, the distance learning of social studies conducted at middle schools in Seoul was observed and in-depth interviews with teachers were conducted. As a result, first of all, social studies teachers were mainly providing video contents and assignments. Second, in terms of class organization, each phase of the class was clearly divided, and teachers perceived inducing interest from students at the beginning of the class as an important factor. Third, in terms of class content, the contents of the class were reorganized around the key concepts of social studies. Fourth, teachers grew little by little by learning synchronous interactive classes and various online participatory technology tools and using them in the distance learning, which was further activated through the social studies teachers’ council. However, the sudden introduction of the distance learning without sufficient preparation also revealed limitations. First, as classes focused on knowledge transfer were conducted, value, attitude, and behavior areas of social studies were neglected. Second, most of the assignments presented as student activities consisted of fill-in-the-blank assignments, and online-based inquiry activities had limitations in that students would passively participate in formalized inquiry procedures to learn the definitive knowledge presented in textbooks. Third, it has been shown that interactions between teachers and students are concentrated on procedural interactions, and there is a lack of cognitive interactions in which authentic learning can actually occur. In terms of evaluation, there was a problem of inconsistency between the instructor and the evaluator, and the problem of separating the class from the evaluation was revealed as well.

본 연구는 임상현장에 의뢰된 아동을 발달장애, 행동장애, 정서장애 집단으로 분류하고, 대응분석을 통해 놀이표현형태의 인지 요소의 속성과 내용을 파악하여, 아동기 장애집단별 놀이표현형태의 임상적 프로파일 자료를 제시함으로써 보다 효과적인 치료자의 반응 방법과 치료목표를 설정하는데 그 목적이 있다. 본 연구의 결과 인지 요소의 장애 집단별 임상적 프로파일의 속성 중 인지수준은 발달장애와 정서·행동장애 간에 뚜렷한 차이를 보여주었으며, 인지적 표현방식은 정서장애와 행동장애 아동 간에 차이를 보여주었다. 인지수준에서 발달장애 아동은 매우 부족한 것으로 나타났으며, 반면 정서장애와 행동장애 아동은 인지적 수준이 적절하여 서로 유사한 속성을 보여주었다. 인지적 표현방식에서는 정서장애아동은 놀이에 대한 언어적 표현과 놀이의 논리적 전개 수준이 우수하게 나타났으며, 반면 행동장애 아동은 놀이전개의 창의성 수준이 우수한 속성을 가지는 것으로 나타났다. 아동기 장애 집단에 따라 인지요소에 대한 임상적 프로파일 내용(사용수준, 내용수준, 확장수준, 논리수준, 창의수준, 언어이해, 언어표현)은 차이가 나타났다. 발달장애 아동은 사용수준, 내용수준, 확장수준, 논리수준 및 전반적인 영역에서 모두 매우 적절하지 못하다고 나타났고, 행동장애 아동은 확장 수준, 창의 수준이 매우 적절한 반면 논리적 수준이 적절하지 못한 것으로 나타났다. 그리고 정서장애 아동은 사용수준, 논리 수준, 언어적 이해와 언어적 표현 수준이 매우 적절했고, 확장수준이나 창의 수준은 적절하지 못한 것으로 나타났다. 본 연구는 놀이라는 매체가 장애 집단별 아동의 인지 발달 수준을 평가하는데 필요한 많은 정보를 제공하고 있다는 사실을 실제 임상현장에 의뢰된 사례분석을 통해 제시하였으며, 이러한 놀이정보를 통해 아동의 장애 집단별 특성에 맞는 효과적인 반응법과 치료목표를 설정하는데 필요한 임상적 프로파일 자료를 제시하였다는데 의의가 있다. The purpose of this study is to investigate clinical characteristics and attribution of children treated with play therapy for developmental, behavioral, and emotional disorders. Subjects of this study were 118 three- to nine-year-old children randomly selected from children who were receiving or already completed play therapy at one of the child and family counseling centers in Cheong-Ju City. The results showed that the cognitive level was lower in children with developmental disorder than children with emotional or behavioral disorder. The cognitive level of children with emotional or behavioral disorder was proper. Children with emotional disorder were superior in terms of linguistic expression and logical development, and children with behavioral disorder were superior in the creativity level of play expression. Children with developmental disorder showed very inappropriate levels of clinical profiles: use, extension, logic, and general areas. Children with behavioral disorder showed proper levels of extension, contents, and creativity although their level of logic was inappropriate. In addition, children with emotional disorder showed very appropriate levels of use, logic, and linguistic comprehension and expression, but their levels of extension and creativity were inappropriate.

참여학습형 법교육 방법으로서 봉사학습(Service-Learning)의 적용에 관한 연구

황미영 ( Mi Young Hwang ) 한국법교육학회 2009 법교육연구 Vol.4 No.2

사회과의 한 분야로서 법교육은 `준법의식을 갖춘 책임 있는 민주시민`을 양성하는 것을 목표로 한다. 또한 최근 사회과교육에서는 시민으로서의 행동과 참여를 강조하는 경향이 나타나고 있다. 그럼에도 불구하고 우리나라의 법교육은 학생들에게 참여의 기회를 제공하지 못하고 있다. 따라서 학생들이 학교와 지역사회에서 발생하는 문제를 해결하도록 참여시키고 이를 통해 민주시민의식을 고양시킬 수 있는 참여학습형 법교육 방법이 강구되어야 한다. 이러한 측면에서 본 연구에서는 참여학습형 법교육 방법으로서 `봉사학습(service-learning)`을 제안한다. 봉사학습은 경험교육의 한 형태로서 학생들이 교실에서 배운 학문적 지식을 활용하여 지역사회에서 실제 봉사활동을 수행하고, 경험에 대한 반성을 통해 학생들의 시민성 함양을 도모한다. 따라서 법교육에서 봉사학습이 갖는 의의와 필요성을 규명하고, 봉사학습수업 모형을 탐색하여 『법과 사회』과목에서 활용할 수 있는 교수-학습 활동의 사례를 제시하고자 한다. 봉사학습을 통해 학생들은 학교에서 배운 지식을 내면화하고, 실제 사회를 폭넓게 경험할 수 있는 기회를 가짐으로써 자신이 속한 사회에 대해 공동체의식과 책임의식을 갖게 되어 민주시민성을 획득하게 되고, 나아가 지역사회의 발전에도 기여할 수 있게 될 것이다. The purpose of law-related education as a part of social studies education is cultivating the democratic citizen who has a responsibility and law-abiding conciousness. And recently social studies education lays emphasis on participation and action as a citizen. But the existing law-related education doesn`t provide opportunities of participation to students. To provide students with opportunities to participate in resolving the problems in the school and community, participatory approach of law-related education is needed. This article suggests service-learning as a means of the participatory approach of law-related education program. A service-learning as a subset of experiential education can let students serve in the community appling the knowledge which they learned in the classroom. And it cultivates the students` citizenship through reflection on the service experience. Therefore, this study aimed to identify the necessity of service-learning and develop a service-learning teaching model for the participatory approach of law-related education. Through a service-learning, Students can internalize the legal knowledge and have an opportunity to experience the real society. Furthermore, they can contribute the development of community.

This study attempts to examine the effectiveness of participation in the student government activities and classroom climate on the formation of students`` political attitudes. In exploring these questions, I conducted a survey of 357 middle school seniors and verified the result by using regression analysis. The findings of the study show that first, serving as a class officer and participating in a class meeting have a positive impact on students`` political confidence, political trust, and political interest. Second, an open classroom climate fosters students`` political confidence, political trust, and political interest. And the result shows that classroom climate is the most powerful factor in the formation of students`` political attitudes. Third, classroom climate has a modifying effect on the participation in class meetings and class events. In other words, even the same participation in class meetings or class events it has a stronger impact on students`` political attitude in an closed classroom climate than an open classroom climate. These research findings suggest that students`` participating experience is essential for citizenship education and creating an open classroom climate is of the utmost significance where students can express their opinions freely and a wide variety of views are respected.

중학교 사회 교과서의 논쟁문제 유형 및 논쟁문제 교수학습 과정 분석

황미영 ( Hwang Mi-young ),박선운 ( Park Sunun ) 한국사회과교육학회 2021 시민교육연구 Vol.53 No.3

This study examines controversial issues (CIs) presented in the Korean middle school social studies textbooks. It focuses on (a) the subject areas and units that CIs are presented in, (b) the types of CI questions, and (c) learning instruction for the CIs within the textbook materials. Following are the analysis results: first, most CIs were found in law and politics-related areas and dealt with a few topics. Second, in the analyzed textbooks, specific case issues were more used than perennial issues, public more than private issues, and open issues more than settled issues. Third, only a few materials in the textbooks included all four steps of CIs instruction―learning the background information of the CI, studying perspectives of pros and cons, discussion with classmates, and making a decision. Most textbook materials provided the CIs’ background information and then asked students to make their own decision. Based on the analysis results, this study provides suggestions for better CIs teaching and learning in middle school social studies classes.

이 연구는 전공만족도 진로결정자기효능감을 매개로 전공만족도가 취업준비행동에 미치는 영향을 연구하여 4차 산업혁명시대 특성화고등학교 졸업생들이 지역인재로 잘 성장할 수 있도록 도움을 주고자하였다. 또한 부산지역 특성화고등학교 학과개편과 학과재구조화의 이론적 근거와 기초자료가 되는 것에 목적을 두었다. 이를 위해 특성화고등학교 학생들의 취업준비행동에 영향을 주는 전공만족도와 진로결정자기효능감을 분석하였고 전공만족도와 취업준비행동에서 진로결정자기효능감의 매개효과를 검증하였다. 연구결과는 다음과 같다. 첫째, 배경변인에 따른 특성화고등학교 3학년이 전공만족도를 살펴보면, 여학생이 남학생보다 전공만족도 전체와 하위요인 일반만족, 인식만족, 교과만족, 관계만족에서 모두 높았으며 진로결정자기효능감 하위요인 중 직업정보수집이 제일 높았다. 둘째, 전공만족도가 높을수록 진로결정자기효능감이 높을수록 취업(진로)준비행동이 높게 나타났다. 전공만족도 하위변인 중 일반만족, 인식만족, 교과만족, 관계만족이 취업준비행동에 영향을 주었고 진로결정자기효능감에서는 직업정보수집, 목표설정, 계획수립이 취업준비행동에 영향을 주는 것으로 나타났다. 셋째, 전공만족도와 취업준비행동관의 관계에서 진로결정자기효능감이 매개효과를 하는 것으로 나타났다. 이상의 연구결과를 바탕으로 특성화고등학교 학생들의 취업준비행동에 영향을 주는 전공만족도와 진로결정자기효능감의 관계를 밝혀 자신의 진로와 취업에 도움을 줄 수 있는 정보를 제공하고자한다. 아울러 취업과 학생모집으로 어려움을 겪고 있는 특성화고등학교의 학과개편과 재구조화 정책을 위한 제언을 제시하여 특성화고등학교가 성장하고 발전할 수 있도록 도움을 주고자한다. The purpose of this study is to study the effect of major satisfaction on job preparation behavior through career decision-making self-efficacy, and to serve as the theoretical basis and basic data for department reorganization and academic restructuring of graduates of specialized high schools in the 4th industrial revolution era. To this end, a correlation analysis was conducted to find out the factors of major satisfaction and career decision-making self-efficacy that influence the job preparation behavior of specialized high school students. The research results are as follows. First, when looking at the degree of major satisfaction according to the background variable, female students had higher major satisfaction, general satisfaction, perception satisfaction, and relationship satisfaction than male students, and job information collection was the highest. Second, there were differences in major satisfaction, career decision-making self-efficacy, and sub-factors of job preparation behavior by region. Third, the higher the major satisfaction, the higher the career decision-making self-efficacy, the higher the employment (career) preparation behavior. Based on the above research results, the purpose of this study is to provide information that can help students in their careers and employment by illuminating the relationship between major satisfaction and career decision self-efficacy that affects job preparation behaviors of specialized high school students. In addition, it is intended to help specialized high schools grow and develop by suggesting policies for department restructuring and restructuring of specialized high schools that are experiencing difficulties due to employment and student recruitment.
