이 연구목적은 2015 개정 교육과정에 따른 중학교 기술·가정 교과서 주생활 단원에 SDGs의 내용이 어떻게 반영되어 있는지 알아 보기 위해 지속가능발전목표(SDGs)의 세부목표를 기준으로 주생활내용을 분석하는 것이다. 이 목적을 이루기 위해 5종 기술·가정 교과서 10권에서 '주생활 문화와 주거 공간 활용', '주거환경과 안전'을 내용요소로 하는 본문, 사진·그림·표·그래프·삽화, 활동과제, 보충자료를 SDGs 세부목표를 기준으로 내용분석 기법을 사용하여 분석하였다. 분석방법은 교과서의 모든 내용을 전사한 다음, 문장을 맥락을 가진 의미 단위로 묶어서 내용분석의 기본단위(내용단위)로 만들었다. 내용단위가 SDGs의 세부목표와 관련되는 있는지 확인한 후에 세부목표별로 빈도분석을 하고, 내용을 제시하였다. 내용단위가 여러 가지의 SDGs 세부목표를 포함하고 있는 경우에는 관련된 세부목표 모두를 중복하여 빈도에 포함시켜 분석하였다. 5종의 교과서를 분석한 결과 내용단위수는 412이며, 내용단위가 SDGs의 세부목표와 관련된 빈도수는 568로 나타났다. 이는 '주생활' 단원은 SDGs와 관련이 많은 것으로 해석된다. SDGs의 17개 목표, 169개 세부목표 중에서 '주생활' 단원과 관련된 SDGs는 11개 목표, 25개 세부목표로 분석되었다. 이중 목표 4의 세부목표 4.7은 지속가능발전교육을 포괄적으로 담고 있어 어느 내용과도 관련되므로 제외하고, 10개 목표, 24개 세부목표를 15개 세부목표기준으로 일부 통합하였다. 5종 교과서에서 '주생활' 단원의 4개 각 소단원은 6~10가지의 SDGs 세부목표기준과 관련이 있었다. 5종 교과서 1권의 내용은 9개의 SDGs 세부목표기준을 담고 있었고, 교과서 2권보다 3개가 더 적었다. 소단원별 SDGs와의 연관성을 분석한 결과 모든 교과서의 모든 소단원의 내용이 SDGs의 세부목표 11.1(적절하고 안전한 주택 및 기본 서비스)을 공통적으로 포함하고 있으며, 이는 전체 주생활 내용단위의 43.8% 차지하는 대표적인 세부목표이다. 이 연구결과는 주생활교육을 거시적인 지속가능목표와 연관하여 이해하고 세계시민교육의 방향에 맞춰 교육을 확장하며 나아가 가정교과가 학교현장에서 지속가능발전교육을 실현하는데 기초자료로 활용될 수 있을 것으로 기대된다. The purpose of this study is to analyze the contents of 'housing' unit in middle school Technology-Home Economics textbooks according to the 2015 revision curriculum based on the targets of SDGs. All contents of the ten textbooks of five publishers, such as texts, photographs/figures/tables, activity tasks, and supplementary materials were analyzed in terms of SDGs targets. The number of 'housing' contents among 4 small housing units of Technology-Home Economics book 1 & 2 varied from 64 to 97 by publishers. Beside SDGs4.7, which contains inclusive and general ESDGs, 24 targets of 10 SDGs were found to be related to the contents of 'housing' and were grouped into 15 target categories. The number of SDGs target categories related to housing contents of each small unit and total of all units differed by publishers. Each of 4 small 'housing' units from all the five publishers was related to 6~10 target categories. The contents of five book 1's were related to smaller number of target categories than those of five book 2's. They corresponded to 9 and 12 target categories, consecutively. Only SDGs' target11.1 (appropriate and safe housing and basic services) was related to all the four small units of 'housing' contents among all the five publishers. covering 43.8% of the housing contents. In conclusion, the contents of the 'housing' unit were related to broad range of SDGs targets. Further study could relate goals of teaching-learning plan to various global targets of SDGs according to the contents of 'housing' in order to accomplish ESDGs.

최성연,이영선,최예지,주현정,김승희,박미정,Choi, Seong-Youn,Lee, Young-Sun,Choi, Ye-Ji,Joo, Hyun-Jung,Kim, Seung-Hee,Park, Mi-Jeong 한국가정과교육학회 2018 한국가정과교육학회지 Vol.30 No.3

본 연구의 목적은 2015 실과(기술·가정) 교육과정에 따라 개발된 중학교 교과서에서 '식생활' 단원의 활동과제를 다중지능 활용 교수·학습방법을 기준으로 분석하는 데 있다. 이러한 목적을 이루기 위해서 12종의 중학교 기술·가정 교과서에서 '청소년기의 영양과 식행동', '식사의 계획과 선택', '식품의 선택과 안전한 조리'를 내용 요소로 하는 본문 내용과 읽을거리, 평가 문항을 제외하고 학생들이 활동할 수 있는 과제를 다중지능 활용 교수·학습방법을 기준으로 분석하였다. 분석방법은 내용분석 기법을 사용하여 학습 활동에 중심을 두고 분석하였고, 활동과제의 하위 질문들도 모두 각 한 가지의 활동으로 분리시키되, 연속선상에 있는 활동을 준비하는 과정은 한가지로 묶어서 분석하였다. 3인이 활동과제를 분석하고 협의를 통해 분석기준을 수정·보완하는 과정을 2회 진행한 후 다른 연구자 3인이 확인하였다. 12종의 교과서를 분석한 결과 활동과제의 수는 교과서 종류별로 25~74개로 나타났으며, 활동과제의 수는 총 527개였다. 다중지능 영역별 비율을 살펴보면, 논리수학지능을 활용한 활동과제가 35%로 가장 많은 것으로 나타났으며, 언어지능 26.8%, 개인내적지능 23%, 대인관계지능 7.2%, 시각운동지능 3.8%, 신체운동지능 2.7%, 음악지능 1.5% 순으로 나타났다. 반면, 자연탐구지능을 활용한 활동과제는 없는 것으로 분석되었다. 자연탐구지능을 제외하고 전반적으로 다중지능을 활용하고 있었는데 이는 가정 교과가 실천을 본질로 하면서 식생활과 관련된 다른 교과의 내용이나 방법을 추출하여 새롭게 재조직한다는 점에서 가정 교과의 융합적 성격을 나타내는 것으로 해석된다. 본 연구는 다양한 교수·학습방법의 틀을 마련하여 학생 참여형 수업을 활성화하고, 가정 교과에서 융합 교육을 실현하는 데 대안을 제공할 것으로 기대된다. The purpose of this study is to analyze the tasks of 'dietary life' in the textbook developed according to the 2015 revised middle school 「Technology·Home economics」 education curriculum based on the multiple intelligence teaching and learning methods. To accomplish this purpose, 12 textbooks of middle school 「Technology·Home economics」 textbooks were titled "Nutrition and Dietary Behavior of Adolescents", "Planning and Choosing Meals", "Choosing Foods and Safe Cooking" except the questions, the tasks that the students can perform are analyzed based on the teaching and learning methods using multiple intelligences. Analysis methods were analyzed by using contents analysis method, focusing on learning activities, and sub-questions of activities were all included in each activity, and the process of preparing activities on a continuous line was grouped into one. Three people analyzed the activities and proceeded to revise and supplement the analysis standard through consultation. The other three researchers confirmed it. As a result of analyzing 12 kinds of textbooks, the number of activity tasks was 25~74 for each kind of textbooks, and the total number of activities was 527. According to the ratio of multiple intelligences, 35% of the tasks were using logical-mathematical intelligence, and 26.8% of linguistic intelligence, 23% of intrapersonal intelligence, 7.2% of interpersonal intelligence, 3.8% of spatial intelligence, bodily-kinesthetic(2.7%) and musical intelligence(1.5%). On the other hand, it was analyzed that there is no activity task using naturalist intelligence. Except to the naturalist intelligence, general intelligence was utilized. This indicates that the home economics curriculum is a convergence of the home economics curriculum in that it is a reorganization by extracting the contents and methods of other curriculum related to dietary life, is interpreted. This study is expected to provide a framework for various teaching and learning methods to activate students' participation classes and to provide an alternative to realize convergence education in home economics curriculum.

목 적: 뇌종양은 소아에서 가장 흔한 고형암종이다. 이번 연구는 15년간의 임상적 고찰을 통해 나이, 성별, 종양의 위치에 따라 소아 뇌종양을 분류해 보았고, 각각의 총생존율을 조사해 보았으며 또한 일부 질환에서는 항암제 추가여부가 생존율에 미치는 영향에 대해서도 조사해 보았다. 방 법 : 1985년 1월부터 2001년 9월까지 세브란스병원에서 진단받고 치료받은 354명의 소아 뇌종양 환자를 대상으로 임상적 기록에 의거하여 후향조사하였다. 결 과 : 소아 뇌종양의 호발 연령은 5-10세와 10-15세가 큰 차이 없이 모두 높았고 남녀비에서는 남자가 조금 우세하였다. 위치별 빈도는 천막상종양(52%)과 천막하종양(48%)에서 비슷하였으나 천막상종양이 근소하게 많았다. 가장 호발하는 종양의 종류는 수모세포종/원시신경외배엽성종양으로 87례(24.6%)였고 다음으로는 소뇌 성상세포종으로 50례(14.1%)였다. 수모세포종, 소뇌 성상세포종, 대뇌 성상세포종은 10년 생존율이 59.4%, 79.3%, 71%로 비교적 예후가 양호하였다. 뇌간교종과 다형성아교모세포종은 10년 생존율이 12.7%, 13.3%로 예후가 불량하였다. 수모세포종의 고위험군에서는 항암제를 사용한 경우에서 사용하지 않은 경우보다 10년 생존율이 유의하게 높았다(54.5%와 40%, P<0.05). 결 론 : 본 연구는 단일기관의 다수의 환자를 대상으로 15년간의 장기간동안 치료 결과를 추적 관찰하여 기타 문헌과의 비교를 해보았다. 수술기법과 방사선, 항암제의 병합요법으로 뇌종양의 생존율 향상이 보고되고 있는바 본 연구에서도 최근 보고처럼 생존율의 향상을 볼 수 있었다. 특히 고위험군 수모세포종의 경우에서는 추가로 항암제를 사용한 경우 생존율이 높아짐을 볼 수 있었다. Purpose : Brain tumors are the most common solid tumor in children. We retrospectively investigated the clinical characteristics of pediatric brain tumors, such as age, sex, tumor site and survival, as seen in a single institution over the last 15 years. We tried to evaluate the role of chemotherapy on the survival of some brain tumors. Methods : Three hundred fifty four children with primary brain tumor who were treated at Severance Hospital from Jan. 1985 to Sep. 2001 were enrolled. Results : Pediatric brain tumors were found most frequently in 10-15 years of age group(35.3%) and the ratio of male to female was 1.3 : 1. Supratentorial tumors(52%) were more frequent than infratentorial tumors(48%). Medulloblastoma/primitive neuroectodermal tumor(PNET) was the most common type(24.6%), followed by cerebellar astrocytoma(14.1%). Ten year survival rate of medulloblastoma, cerebellar astrocytoma and cerebral astrocytoma were 59.4%, 79.3% and 71%, respectively. The prognosis for brain stem glioma and glioblastoma multiforme were still grim with a 10 year survival rate of 12.7% and 13.3%, respectively. The addition of chemotherapy for high grade medulloblastoma led to an improved 10 year survival rate of 54.5%, compared with 40% without chemotherapy. Conclusion : The combined use of chemotherapy and radiation and surgery improved survival rate of pediatric brain tumors in our study. Chemotherapy for high grade medulloblastoma improved the 10 year survival rate. Further data analysis of the treatment modalities will lead to better comparisons.

본 연구는 국내 문학관 웹사이트의 정보 제공 현황을 파악하여 문학관 온라인 정보서비스의 개선 방안을 제시하는 데 목적이 있다. 연구의 대상은 한국문학관협회 88개 회원관 중 웹사이트가 구축되지 않은 9개관을 제외한 79개관으로 하였다. 문학관의 운영과 문화기관의 온라인 서비스 현황 및 개선 방안에 관련된 선행연구를 참고하여 웹사이트 유형, 문학 정보, 문인 정보 등 3개의 조사 항목과 13개의 세부 조사 항목을 도출하였다. 조사의 결과 국내 문학관의 웹사이트 구축률은 약 90%로 매우 높았으나, 문학 정보의 분류 기준 및 목록정보의 기술이 통일되지 않았고, 문학 자료의 제공이 활성화되지 않은 것으로 나타났다. 이를 개선하기 위한 방안으로 웹사이트 구축 지원, 문학관에 적용 가능한 목록 가이드라인 개발, 원문 제공 활성화, 문학·문인 관련 정보의 제공 등을 제시하였다. This study is to present improvement plans by examining how Korean literature house websites provide information services. Seventy-nine Korean literature houses out of eighty-eight members of the Korean Literature House Association were studied, except nine that did not construct websites. Three core elements, including website style, literary works information and writer information, together with thirteen sub-elements, were derived from precedent studies. As a result, it was found that 90% of the literature houses were operating websites, but the classification criteria for the literary works and cataloguing rules were not unified, and literature information was not provided sufficiently. Thus, this study suggested improvement plans such as support to build a website, developing cataloging guidelines for literature houses, providing more full-text literature and providing information about literary works and writer.

This study develops and evaluates a game-based lesson plan applied to the ‘Food Culture’ unit of a high school Home Economics class. We developed, implemented, and evaluated lesson plans for seven periods that contained ‘the Korean food table setting card,’ ‘the world’s food culture card,’ and the procedure for cards games according to the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model. ‘The Korean food table setting card’ consisted of ‘the Korean food table setting order card’ to easily understand 10 types of Korean traditional daily meals based on pictures and ‘the Korean food table setting food card’ to easily understand Korean traditional food based on 104 kinds of food picture and quick response (QR) code. ‘The world’s food culture card’ consisted of ‘the world’s food culture quiz card’ to help learners easily understand influential food culture formation factors, features of food culture, typical foods from 16 countries, and ‘the world’s traditional food card’ to help learners easily understand typical foods from 16 countries through 63 kinds of pictures. Respective ‘game guides’ were also developed. High school students who studied the game-based Home Economics classes and who participated in the ‘Food Culture’ unit, could easily and enjoyably learn the food culture of Korea (and other countries), actively participate in learning activities, and understood the content of food culture. In addition, they evaluated that the game-based instruction was easy to remember with minimal memorizing.

The objective of this study was to conduct a ‘Theory of Home Economics Education’ class using online problem-based learning(PBL) for prospective home economics(HE) teachers. The aim was to enable teachers to analyze the learning experience in the classroom, and to prepare operational strategies for online PBL on this basis. In order to achieve this, online PBL was applied to 31 students participating in the ‘Theory of Home Economics Education’ at the Department of HE in a university in Seoul, and the results were collected from the learning process. This also involved a reflective journal, a survey on the learning experience and the impacts was conducted. Moreover, analysis was undertaken on the learning activities, learning difficulties, and improvements. The main research results are as follows. Firstly, students accessed Webex, an online video conferencing program, and performed two PBL tasks: ‘Making Home Economics Promotion Materials’ and ‘Presenting Teaching Strategies to Improve Learner's Immersion in Online Classes’. Secondly, learners established their own identity of HE learned about the HE class plans themselves. They also encountered realistic experience as HE teachers and learned communication and collaboration skills. Furthermore, they acquired creative problem-solving and self-directed learning ability, community consciousness, as well as the attitude of consideration and respect. Thirdly, students lacked knowledge of learning content and encountered difficulty in solving data research, analysis processes, and unstructured problems. They were affected by a lack of time and encountered problem in communicating with other team members in an online environment. As an improvement in online class operation, it was considrered necessary to reduce the learning burden by securing time and reducing the number of assignments, as well as to explain active interaction with instructors and PBL.

This paper presents a case study in which a lesson was designed and applied to enhance preservice home economics teachers' instructional design competence using the metaverse. For 15 weeks from March 6 to June 14, 14 students enrolled on the course 'Multimedia Home Economics Education' for preservice home economics teachers used the metaverse to engage in problem-based learning to solve instructional design problems in home economics classes. In accordance with the ADDIE design model, in the analysis stage, we assessed preservice home economics teachers’ level of knowledge of lessons using the metaverse, and their perceptions of the possibility, necessity, and usefulness of using the metaverse in home economics lessons. In the design and development stage, lesson plans, questions for problem-based learning, assessment tools, and teaching and learning materials were developed. The implementation was conducted in parallel with training on understanding multimedia and the metaverse, and instructional design competence was evaluated through pre- and post-testing and reflection journals. The results revealed that the preservice home economics teachers acquired a good understanding of lessons using the metaverse, learned how to design lessons for self-directed learning by applying the metaverse to their home and classroom, and gained confidence in applying it to their teaching practice or in-service work. It is expected that the results of this study will be used as support materials for prospective and current home economics teachers to design home economics lessons using the metaverse, thereby expanding the horizons of home economics education.

평균 처리율을 고려한 RFID 시스템의 하이브리드 충돌 방지 기법

최성연(Choi, Sung-Yun),이제호(Lee, Je-Ho),김성현(Kim, Sung-Hyun),차균현(Tchah, Kyun-Hyon) 한국전기전자학회 2010 전기전자학회논문지 Vol.14 No.2

현재 Slotted-ALOHA 방식과 Binary-tree 방식의 충돌 방지 방식이 많이 연구되고 있으나, 인식 시간의 지연 및 시스템 구현 시 복잡도 등으로 실용적인 측면에서는 더 많은 문제를 해결해야 될 필요가 있다. 본 논문에서 이를 해결하기 위하여 Slotted-ALOHA 방식과 Binary-tree 방식을 혼합한 방법으로 태그를 여러 개의 그룹으로 나누고, 각 태그 그룹은 Slotted-ALOHA 방식을 이용하여 인식 작업을 수행하는 하이브리드 충돌 방지 기법이다. 한 그룹의 태그의 수는 시스템 처리율(Throughput)이 최대가 되는 태그의 수로 결정한다. 제안하는 하이브리드 충돌 방지 방식과 기존에 사용되고 있는 방식들을 태그의 인식 시간과 처리율 측면으로 비교하기 위하여 컴퓨터 시뮬레이션을 하였다. 제안하는 충돌 방지 기법은 기존의 방법보다 빠른 태그의 인식시간과 우수한 처리율을 보여서 현재의 RFID 시스템의 성능을 더욱 높일 수 있으리라고 예상된다. Slotted-ALOHA and Binary-tree method are researched for the anti-collision for RFID system. However, it is required of the rapid recognition time for all tags and the reduction of the system complexity. In this paper. the hybrid anti-collision method is proposed to solve the problems. The RFID reader with the hybrid anti-collision method groups the tags with the number which makes the maximum system throughput, then it reads each group by slotted-ALOHA method. By the computer simulation results, it is found that the hybrid method improves the tag identification time and the system throughput together with the comparison to other anti-collision methods. Therefore, the proposed hybrid anti-collision method will enhance the RFID system performance.

일학습병행 재직자학위연계 교육과정 참여학생의 학습성과와 대학측 대응 노력 간의 연관성 고찰

The degree-linked programs for employees, operated by joint training centers in specialized universities that have implemented work-study integrated programs, are educational programs that require an annual government budget of around 80 billion KRW. However, the 70+ universities running these programs face issues such as a decline in academic achievement and an increase in dropout rates among students. In this paper, I conducted multiple regression analysis based on observed and measured information to examine whether the participating students in these programs are achieving an appropriate level of academic performance and to identify the factors that universities need to invest in to achieve that level. To do this, I hypothesized a causal relationship between the university's input factors and students' academic achievement, and used the SPSS program to analyze the statistical data, confirming the validity of the hypothesis. The collected data for the study were obtained through a survey developed using a Likert 4-point scale, which quantified the distribution of grades among students enrolled in IT-related departments offering the degree-linked programs for employees and the emotional contact efforts made by the universities to motivate them for academic success. Particularly, through the results of multiple regression analysis, it was confirmed that these input factors, unlike those for students in general education programs, require more personalized and frequent interactions.
