The purpose of this study was to examine the perception of elementary school students about pseudo-science and the differences of view on pseudo-science among groups of religion. The subjects in thisstudy were 242 fifth graders and 200 sixth graders, who were tested to figure out their view ofpseudo-science. The findings of the study were as follows. First, as for their awareness of pseudo-science, they generally took a dismal view of the four areas of pseudo-science, including astrology,allusion, magic arts and supernatural phenomena, and there was little change in their view even thoughthey moved up to a higher grade. It indicated that despite continuous science learning, their cognitivepattern remained unchanged. And, Elementary students' religion exerted an influence on their awarenessof the four areas of pseudo-science. Specially, Buddhists are more permissive views than other religiongroups.

In this research, we have focused on the tendency of researches on the education of gifted-in-science. For this concern, it has been performed to filter, according to the classification standard, thenumber of research papers from papers on academic magazines during the period from the early 1990to November 11th 2007. While there were a lot of related papers in the early 1990 when it was thebeginning period of time to perform the researches on the education of gifted-in-science, there has beena tendency of decreasing the number of researches. In addition, it is also revealed that the researcheswere much skewed to the education of gifted-in-science and its educational course work. Under thedeep consideration on the environment that the interest on the education of gifted-in-science has beenincreased and that the education has been performed widely, more various and more in-depth studiesshould be made such as the educational method which can match the unique characteristic of eachgifted-in-science, the research on defined characteristic related with the gifted-in-science’s attitude, andthe ideal attitude of teachers toward the gifted-in-science according to the analysis of the interactionbetween teachers and students.

지난 2003년 1월 25일 오후 국내 최상위 DNS(도메인 네임 시스템)서버가 다운되면서 유.무선 인터넷 서비스가 일제히 마비되는 사상 초유의 사태가 벌어지고 전국 곳곳에서 크고 작은 혼란과 피해를 빚었다. 원인은 여러 가지의 형태로 분석되었지만 가장 큰 이유는 보안 불감증에서 기인했다고 할 수 있다. 특히 소규모 네트워크에서 보안관리자는 거의 없고 정보보호를 위한 물리적인 장치가 전무한 상태였다. 대부분의 보안시스템이 경제성을 이유로 대규모 네트워크에 중점적으로 개발되고 있으며 실시간으로 네트워크의 보안상태를 점검해 주는 보안관제센터들도 IDC나 대규모 네트워크를 중점으로 서비스 되는 실정이다. 본 논문에서는 제기되어온 문제점을 해결하기 위하여 소규모 네트워크 전용 SnSA를 설계하여 경제적인 보안관제 서비스를 연구하였다. 첫 번째로 소규모 네트워크에서 보다 많은 정보를 수집하기 위해서 네트워크 침입탐지기능 N_SnSA와 호스트 침입탐지기능 H_SnSA를 구현하였고 두 번째로 경기대학교 통합보안관제센터와 같은 공익성을 가진 센터에서 저렴한 비용으로 연동시켜 기존의 취약성을 해결하는 방법을 연구하였다.
At the end of last January, 2003, a domestic top-level domain name server (DNS) shut down the server and it caused the wired and wireless internet services to be completely paralyzed in the aftermath of a virus attack incurring a various range of losses nationwide. The main reason of this event is the lack of our awareness of cyber security. In particular, in the small-scale network, there are few security administrators and no operating devices to protect information as well. Under this circumstance, using ESM center to service real-time security supervision and correspondence for network, it can be one option. However, due to the economic efficiency, most of security systems have been being developed focusing on the large-scale network first. Therefore, ESM centers which inspect security state of network concentrate on IDC or large-scale network services. This dissertation studies economical ESM service by designing exclusive SnSA for small-scale network for widespread use. Firstly, network invasion feeler function N_SnSA and host invasion feeler function H_SnSA are embodied to collect more informations in the small-scale network. Secondarily, the existing vulnerability is studied to find the solutions linked with a low cost to a Public center such as Kyonggi Univ ESM center.

천연염료는 여러 조건에서 명도, 채도, 색상이 다양하게 나타날 수 있다. 저자들은 한지 직물에 황색계 염료의 매염제와 매염방법에 따라 나타나는 색상과 색차를 헌터값(Hunter’s value)과 먼셀값(Munsell’s value)으로 염색성을 수치분석 하였다. 1. 매염방법에 따라 염색 효과가 달랐다. 치자, 한련초는 선매염법이 효과적이었으며, 울금, 빈 랑은 매염법에 따른 색상차는 크지 않았고 빈랑은 알루미늄 매염에 의한 효과는 거의 없었다. 2. 효과적인 염색을 위해 매염제에 따라 다른 염색법이 필요하였다. 괴화는 알루미늄 매염의 경 우 후매염, 구리, 철 매염의 경우 선매염이 효과적이었으며, 대황과 호장근은 알루미늄, 구리 매염제의 경우 선매염이 효과적이었다. 3. 황색 색상은 주로 알루미늄 매염제를 사용하였을 때 나타났으며, 치자, 황련은 붉은빛을 띤 노랑(reddish yellow), 울금, 황백, 괴화는 초록빛을 띤 노랑(greenish yellow), 정향, 한련초는 순수한 노랑(pure yellow)을 나타내었다. 4. 황색계 염료의 대부분은 철 매염제를 사용하면 초록빛을 띤 회색(greenish grey)을 나타냈다 . 5. 염착량 K/S값과 색상 농도와의 상관관계는 적었다. 대황의 경우 염착량이 적게 나타났지만 염색 색상은 매우 진한 색상을 나타냈다. 따라서 황색계 천연염료를 이용한 효과적인 천연염색을 위해서는 직물에 따른 적절한 염재 사 용과 이에 알맞은 매염법의 선택이 중요하다.
The natural dyestuff can differ in brightness, chroma, and color under several conditions. We intend to show the difference in color and chrominance of yellow dyestuff that is shown in Hanji fabric, according to mordant agents and mordant methods, using the statistics of Hunter’s value and Munsell’s value. The results from these analyzes are as follows :1. The effects of dyeing differ according to mordant methods. In the case of dyeweed, pre-mordant process was much more effective and in the case of curcuma and betel nut, the difference in color from the utilization of different mordant methods was not noticeable. Moreover, there was almost no change or effect from the use of aluminum mordant in the case of betel nut. 2. In order for effective dyeing, different mordant methods should be implemented according to different mordants. When dyeing with bud of pagoda tree, in the case of aluminum mordant, post-mordant process was effective and in the case of copper, iron mordant, pre mordant process was effective. When dyeing with rhubarb and polygonum cuspidatum, when using aluminum and copper mordant, pre-mordant process was effective. 3. Yellow color usually appeared at the use of aluminum mordant, and gardenia jasminoides, barberry root lead to reddish yellow, curcuma, Amur cork-tree, bud of pagoda tree to greenish yellow and dried clove bud, dyeweed to pure yellow. 4. Most of the yellow dyestuffs showed greenish grey at the use of iron mordant. 5. Amounts of dye uptake, K/S and the concentration of color showed little relevance. Rhubard, for instance, showed low dyeing volume while its dyeing color showed to be very dark and thick. Therefore, in order for effective dyeing using the yellow natural dyestuffs, the use of an appropriate mordant and deciding on the correct mordant method is crucial.

The aim of this study is to analyze STEAM lessons focused on the learner's learning. This study was conducted on 4th-graders in Y city, Kyung-gi province. The lessons were based on a joint teaching plan for students through the teacher learning community (TLC) with three teachers from the same school. Each of the three classes that conducted the class was selected and analyzed as the main center of observation by three students. The conclusions from this study are as follows: First, we identified that different levels of learners are learning in STEAM lessons through a learner-centered class analysis. Some students arrived on their own by taking the initiative in class, others by consulting with a group of friends, and others needed active teacher guidance to learn. Second, Depending on the level and characteristics of the students, some learning criteria were not reached. Some students need guidance at a glance level, and others need individually instructed or guided activities. Teachers need to keep an eye out for students and give them an appropriate level of guidance during class. In STEAM lessons, it appears that students of different levels and characteristics can immerse themselves in their own way, as well as the clear guidance of activity for their students.

본 연구의 목적은 융합인재교육(STEAM) 수업을 위해 같은 학교에 근무하는 동 학년 교사 3명이 교사학습공동체를 구성하여 공동지도안을 작성하고 수업하는 모습을 살펴 시사점을 도출하는데 있다. 본 연구를 통해 다음과 같은 결론에 도달하였다. 동 학년 교사학습공동체는 STEAM 수업을 실행하는데 도움을 준다. 교사들은 교사학습공동체를 통해 STEAM 수업의 어려움을 극복하고 수업을 실행하였다. 본 연구 참여 교사들이 생각한 STEAM 수업의 어려움은 연구시간 확보의 문제, STEAM 수업 진행이 어려운 문제, 그리고 STEAM 수업 연구가 어렵다는 문제이다. 교사들은 교사학습공동체에서 공동지도안을 작성하면서 수업에 대한 부담을 극복하였고 좋은 수업을 설계하기 위한 아이디어를 공유하고 교차 점검하는 등의 노력을 했다. 아울러 공동지도안으로 실행한 수업을 서로 참관하면 지도안을 작성할 때 미처 생각하지 못했던 수업 진행상의 어려움을 새롭게 발견하였다. 이를 개선하여 수정된 지도안으로 점점 더 좋은 수업을 하게 되었다. 즉, 학생들이 좀 더 학습 목표에 수월하게 도달하고, 수업 안에서 배움이 더 잘 일어나게 되었다. 이러한 과정을 통해 교사들은 스스로 성장하고 있음을 느꼈다.
The purpose of this study is to construct a Teachers' Learning Community (TLC) with three teachers from the same school and to develop a joint teaching plan for students through the TLC. The conclusions from this study are as follows: The TLC with the same grade helps teachers to implement STEAM classes, where teachers overcame difficulties of STEAM lessons and successfully implemented them. Teachers in this study expressed difficulties of STEAM lessons including lack of time, difficulties of STEAM lesson implementation, and difficulties of developing a good STEAM lesson. Teachers worked together to develop a common teaching plan, to overcome the burden of teaching, and to plan better lessons through discussions and cross-checking. In addition, teachers newly discovered difficulties of lesson implementation as they watch each other teaching using a joint lesson plan. Teachers will conduct a better lesson as they improve these difficulties, where a better lesson means having students reach learning goals and learn from the lesson. Teachers in TLC felt that their lesson improved and they themselves growing through a series of courses of watching and learning each other's lessons.

The purpose of this study was to analyze the character of the creative design processes that appear at the creative design stage of the design thinking based on STEAM class and what factors affect the creative design process. Students who served as the subjects of this study were 4 elementary school students. We developed the design thinking based on STEAM program to look more specific the creative design process. The project was conducted with a total of 12 sheets of paper materials. The conclusions of this study are as follows. First, the problem solving process of the design thinking based on STEAM classes is not anticipatory and is cyclical and complex. So, teachers should provide sufficient time for students to create and simulate ideas and accept the solving problems through trial and error. Second, Having presented the STEAM class as a practical problem in the real world, there was less fear of students' failure and heightened motivation and enthusiasm. Providing with the real topic and open questions in classrooms can lead to students' voluntary participation in the classroom. Third, In the design thinking based on STEAM class, students develop concrete ideas through visualization courses. The group of students made the best solutions through communication.

The purpose of this research is to study and learn more features how this type of distribution for communication in $6^{th}$ grade first semester elementary science and mathematics according to communicative expression by 2009 revised curriculum. For this study, based on an analysis standard presented in previous research on the types of communication. The results of this research are as follows. First, because the mathematics presents the number of ways to communicate twice more than science, mathematics go through with much more problems to solve than science. Second, in mathematics, spoken method and written method have similar proportion, less in physical activity method. Third, Science showed balanced proportion among four areas; earth, life, energy, and material. On the other hand, mathematics only showed small numbers in the area of geometry but similar numbers in number and operations, regularity, measurement. Fourth, there is no common feature or relevance about communicative approach for convergence thinking in 2009 revised curriculum, it seems that it doesn't consider it as a revised.

In this study, we developed and examined the validity and reliability of the Test for Indicators of Positive Experiences about Science (TIPES) that measures students' positive experiences about science. We have developed TIPES through literature reviews, development of the preliminary version of TIPES, a pilot test and revisions of the preliminary version, and the test of the final version. Through literature reviews and Delpi methods, we developed the preliminary version of TIPES, which consists of five categories such as science academic emotion, science-related self-concept, science learning motivation, science-related career aspiration, and science-related attitude. Using the preliminary version, we conducted a pilot test with 198 students consisting of 4th, 6th, 8th, and 10th graders, and modified the first version based on the results from the pilot test and expert meetings. We then conducted a main test with the revised version of TIPES with 1,841 students consisting of 4th, 6th, 8th, and 10th graders. According to a confirmatory factor analysis, a reliability test and descriptive statistics analyses, TIPES found to have a good validity as well as reliability. In addition, there are statistically significant differences in the norm distribution and scores of TIPES by student's grade, gender, school location, and level of participation in science-related activities. Discussed in the conclusion are the implications of this research for science education research and science teaching and learning practices in the school.

In order to analysis on color difference of yellow natural dyes, I have dyed cellulose and protein fabrics. The results of experiment have been analysed by wavelength of maximum absorption, amounts of dye uptake, color difference, Hunter's value and Munsell's value. The results from these analyses are as follows : Bud of pagoda tree, Amur cork, and Curcuma showed greenish yellow color, Gardenia Jasminoides showed reddish yellow color. Barberry root showed reddish yellow color with post-mordanting method on cellulose fabric. Moreover, Dupioni silk was dyed in reddish yellow color by Barberry root and Rhubarb. In addition to Chroma index, Gardenia Jasminoides and Curcuma showed clear color overall. However, dyeing rayon and silk by Barberry root, and dyeing silk by Rhubarb showed clear color. Comparing all the results to actual dyed materials, Bud of pagoda tree had small dye uptake, and both ${\Delta}a$ and ${\Delta}b$ value were short which can't recognized the yellow color easily. Dye uptake of Amur cork and Gardenia Jasminoides was small just like Bud of pagoda tree. However, ${\Delta}b$ value order was Gardenia Jasminoides>Amur cork>Bud of pagoda tree. Therefore, Gardenia Jasminoides recognized reddish yellow because of big value of red color and yellow color. In case of Barberry root and Rhubarb which have larger dye uptake, Baberry root recognized yellow color on rayon only, and couldn't recognized yellow color on bleached cotton fabric, ramie, silk, and dupioni silk. Rhubarb recognized yellow color on rayon with pre-mordanting method only, but recognized silk and dupioni silk as brown like color. Moreover, we could not analyze color by dye uptake, Lab, and H(v/c) for Barberry root and Rhubarb. As a result, I think we need to attach color table for the research paper which handled the color of dyeing materials.

이 연구의 목적은 과학 학습 관련 정의적 특성 간의 상호작용을 종합적으로 이해하기 위하여 '과학 긍정경험' 구성 변인들 간의 유의미한 경로모형을 규명하는 것이다. 여기서 과학 긍정경험이란 과학학습에 관련된 학생들의 정의적 성취에 긍정적인 영향을 미치는 경험의 총체를 의미하며, 과학 긍정경험에 따른 학생들의 정의적 성취를 구성하는 5개 하위 변인은 '과학 학습 정서', '과학관련 자아개념', '과학 학습 동기', '과학관련 태도', 및 '과학관련 진로 포부'이다. 전국 17개 시도에서 4학년, 6학년, 8학년, 10학년에서 각각 1개 학급 학생들을 임의로 표집하여, 총 1841명을 대상으로 '과학 긍정경험 지표검사(TIPES)'를 사용하여 온라인 설문 조사를 실시하였다. 주요 변인들 간의 구조적 관계를 파악하기 위하여 구조방정식 모형을 선정하고, 최종 구조방정식 모형의 경로계수가 집단 간 차이가 있는지 확인하기 위한 다집단 분석을 실시하였다. 구조방정식 모형 분석 결과, 과학학습 긍정 정서와 부정 정서는 모두 과학관련 자아개념을 경유하여 과학 학습 동기, 과학관련 태도, 과학관련 진로 포부에 영향을 주는 것으로 나타났다. 배경 변인에 따른 집단 간 과학 긍정경험의 5개 하위 영역의 평균 차이를 t-test 검증을 통해 비교한 결과에 따르면, 과학 긍정경험의 5개 하위 영역은 성별, 학교급, 지역규모, 과학관련활동 참여 여부에 따라 평균값이 통계적으로 유의미한 차이가 나타났다. 학생의 배경 변인에 따라 구조방정식 경로모형에 차이가 있는지 알아보기 위해 실시한 다집단 분석 결과를 살펴보면, 성별과 학교급별에 따라서는 집단 간에 경로계수의 차이가 유의미하게 나타난 반면, 지역규모와 과학관련 활동 참여 여부에 따라서는 집단 간 경로계수 차이가 유의미하지 않았다. 결론에서는 본 연구의 결과를 토대로 학습자의 정의적 성취를 돕기 위한 과학교육에의 시사점을 논하였다.
The purpose of this study is to investigate a meaningful path model among the components of students' positive experiences about science and science learning to understand the interactive relationships among different variables of affective domains. Positive Experiences about Science (PES) means whole experiences that have positive effects on students' affectional achievement related with science learning, which consists of science academic emotion, science-related self-concept, science learning motivation, science-related attitude, and science-related career aspiration. We conducted an online survey with 1,841 students consisting of 4th, 6th, 8th, and 10th graders from 17 provinces and cities using Test for Indicators of Positive Experiences about Science (TIPES). To explore the structural relationships among variables, we selected and analyzed an optimal structural equation model and then conducted multigroup analyses among groups. According to the analysis of the structural equation model, 'positive as well as negative science academic emotion' has effects on science learning motivation, science-related attitude, and science-related career aspiration via science-related self-concept. According to the independent t-test results for TIPES scores by participants' characteristics, there were statistically significant differences in the average scores of five sub-components of PES depending on gender, school-level, school location, and participation in science-related activities. According to the multi-group analysis results, the difference of path coefficients by gender and school-level were statistically significant, whereas the difference of path coefficients by school location and participation were not significant. Discussed in the conclusion are the implications of this research for science education research and ways to help students' affectional achievement related with science learning.

본 연구의 목적은 거꾸로 수업의 이점과 한계를 분석하여 실제수업 적용에 효율적인 ALP 모형을 개발하고, 그 효과를 확인하는 데 있다. 새로운 모형과 프로그램 개발 과정은 ADDIE 모형을 기초로 하였다. 먼저 거꾸로 수업의 어려움 분석과 관련된 연구들을 분석하여 새 모형의 주요 구성 요소를 추출하였고, 이 요소들을 수업의 흐름에 따라 재배치함으로써 ALP 모형을 개발하였다. 모형은 요약 강의 참여 단계(Attending a Short Lecture), 갭(gap) 이용 추가 학습 단계(Learning More in a Gap), 학생 중심 학습 수행 단계(Performing Student-centered Learning)의 3단계로 구성된다. 과학적 의사소통능력에 대한 모형의 효과를 살펴보기 위해 ALP 모형을 적용한 초등과학 프로그램을 개발하였다. 추가적인 정보를 얻기 위해서 수업에 대한 인식 조사와 실험집단 학생들 중 일부를 대상으로 면담을 진행하였다. 연구결과는 다음과 같다. 거꾸로 수업의 어려움을 분석한 논문을 살펴본 결과 수업의 흐름에 따라 다양한 종류의 어려움을 확인할 수 있었으나, 주로 사전학습과 관련된 것이었다. 이를 바탕으로 수업 구조적인 변화를 주어 사전학습의 동영상 강의 부분을 다시 교실로 가지고 오고, 자율적인 추가 학습 부분을 교실 밖에 유지하였다. 이를 통해 거꾸로 수업에서 의사소통능력 향상에 도움을 주는 학생중심학습 시간의 증대를 꾀하고, 거꾸로 수업의 사전학습에서 교사의 준비 부담과 학생의 참여 관련 어려움을 줄이고자 하였다. ALP 모형을 적용한 초등 과학 프로그램을 적용한 뒤에 과학적 의사소통능력측면의 효과를 살펴본 결과, 실험집단에서 유의한 향상이 있음을 확인하였다. 세부 결과에서는 표와 그림 형태와 주장형과 정당화 유형에서 유의한 효과를 확인하였다. 이는 학생들에게 학생중심학습의 시간과 기회를 보다 많이 제공한 결과로 볼 수 있으며, 이는 수업에 대한 인식조사나 면담에서도 확인할 수 있었다.
The purposes of this study are to analyze the merits and limits of flipped learning by suggesting the ALP model for efficient application and to test the effects of the new ALP model. The process of new model and program development is based on ADDIE in this study. This study consists of two steps. First through literature research on the difficulties of the flipped learning, the elements are extracted to develop new model. Second, these elements were placed according to the teaching and learning flow, which resulted in the procedures. As a result, the ALP model was developed. The ALP model is a new model for applying teaching and learning methods for efficient application of the flipped learning. This model was applied to elementary science classes to test its effects in scientific communication skill. Interviews and cognitive survey were also conducted to collect additional information. The results of this study are as follows: There were various difficulties in flipped learning. Based on literature research results, the ALP model and the science programs for elementary students have been developed. The experimental group showed statistically meaningful improvement in scientific communication skill. The scientific communication skill has two subcategories: the forms and the types. According to the form analysis results, the experimental group showed a statistically meaningful improvement in the form of Table and Picture, but not in the form of Writing and Number. With the same reason given previously, this study confirmed that the application of ALP model improves the students' visual form communication skills such as Table and Picture better than reading form communication skills such as Writing and Number. According to the type analysis results, the experimental group showed a statistically meaningful improvement in "the scientific insistence" type, and "the justification" which is the sub element of "the scientific insistence" type. With this reason, this study suggests that the class applied ALP model gives students more time and opportunities to learn. Though the survey and interviews about the student's awareness of the class with applied the ALP model, this study showed that students actively exchanged their opinions in the class with applied ALP model.
