Due to COVID-19, changes in consumption trends are taking place in the distribution sector, such as an increase in non-face-to-face consumption and a rapid growth in the online shopping market. However, it is difficult for small and medium-sized export sellers to obtain forecast information on the export market by country, compared to large distributors who can easily build a global sales network. This study is about the prediction of export amount and export volume by country and item for market information analysis of small and medium export sellers. A prediction model was developed using Lasso, XGBoost, and MLP models based on supervised learning and deep learning, and export trends for clothing, cosmetics, and household electronic devices were predicted for Korea's major export countries, the United States, China, and Vietnam. As a result of the prediction, the performance of MAE and RMSE for the Lasso model was excellent, and based on the development results, a market analysis system for small and medium sellers was developed.

Traditional wooden buildings deform over time and are vulnerable to fire or earthquakes. Therefore, traditional wooden buildings require continuous management and repair, and securing architectural drawings is essential for repair and restoration. Unlike modernized CAD drawings, traditional wooden building drawings scan and store hand-drawn drawings, and in this process, many noise is included due to damage to the drawing itself. These drawings are digitized, but their utilization is poor due to noise. Difficulties in systematic management of traditional wooden buildings are increasing. Noise removal by existing algorithms has limited drawings that can be applied according to noise characteristics and the performance is not uniform. This study presents deep artificial neural network based noised reduction for architectural drawings. Front/side elevation drawings, floor plans, detail drawings of Korean wooden treasure buildings were considered. First, the noise properties of the architectural drawings were learned with both a cycle generative model and heuristic image fusion methods. Consequently, a noise reduction network was trained through supervised learning using training sets prepared using the noise models. The proposed method provided effective removal of noise without deteriorating fine lines in the architectural drawings and it showed good performance for various noise types.

A mid-story isolation system was proposed for seismic response reduction of high-rise buildings and presented good control performance. Control performance of a mid-story isolation system was enhanced by introducing semi-active control devices into isolation systems. Seismic response reduction capacity of a semi-active mid-story isolation system mainly depends on effect of control algorithm. AI(Artificial Intelligence)-based control algorithm was developed for control of a semi-active mid-story isolation system in this study. For this research, an practical structure of Shiodome Sumitomo building in Japan which has a mid-story isolation system was used as an example structure. An MR (magnetorheological) damper was used to make a semi-active mid-story isolation system in example model. In numerical simulation, seismic response prediction model was generated by one of supervised learning model, i.e. an RNN (Recurrent Neural Network). Deep Q-network (DQN) out of reinforcement learning algorithms was employed to develop control algorithm The numerical simulation results presented that the DQN algorithm can effectively control a semi-active mid-story isolation system resulting in successful reduction of seismic responses.

This paper analyzes the Korean conjunctives –ko and –ese, and the Turkish converb –Ip, which have various meanings, and reveals their similarities and differences visually using the semantic map model. –ko and –ese are learned at the beginner level but Turkish learners have shown many errors. Those two Korean conjunctives express different temporal meanings, however, the corresponding Turkish converb expressed them in a single form. Korean textbooks have introduced the meanings of –ko and –ese as [sequential] and [continuous], but it can be made more confusing for learners by presenting the meaning using the same term. Therefore, it is necessary to teach the meanings of the two connectives in more detail according to their syntactic characteristics. Since most textbooks of Korean do not clearly present the differences between the –ko and –ese, effective teaching methods for Turkish-speaking learners based on the Focus-on-Form approach are proposed. To teach the conjunctives –ko and –ese, distinguishing between features of different meanings and to recognize those differences is encouraged.

The current study aims at investigating differences, if any, of EFL learners' and teachers' (native and non-native English teachers) perception of the role of grammar instruction and error correction in L2 learning. For this study 617 college students, 53 non-native teachers, and 41 native teachers were asked to respond to a survey questionnaire. The findings were as follows: 1) some discrepancies were evident between the two teacher groups in perception of grammar instruction, while they shared similar perceptions of error correction; 2) the more proficient in English the students were, the more positive perception of the two constructs they showed; and 3) the Korean teacher group and students showed less negative perceptions of grammar instruction than the native teacher group, whereas differences between the students and the two teacher groups were noticeable. Teaching implications are discussed in view of the necessity of exploring students' and teachers' perception of grammar instruction and error correction.

This study examined how smart device applications affected elementary school students who have learning difficulties in English. Five 6th grade students who needed remedial instruction were selected and given 50 hours of instruction using English vocabulary flash cards in a smartphone application. one hundred vocabulary words were chosen and developed for flash cards for the students to examine their intellectual and emotional changes in English learning. The research results showed that the students' vocabulary improved in listening, reading and speaking. It also revealed that the students gained confidence and interest in English learning, and their anxiety decreased. In addition, the application was easy and convenient for the students to use, especially in recognizing the pronunciation and the meaning of the vocabulary words. This study recommends further development and use of smart device applications for elementary school English instruction.

The purpose of this study was to identify the effects of nutrition education on elementary school students based on the theory of multiplex intelligence. Of the 56 elementary school students that participated in this survey, 37 (66.0%) had no siblings. The number of students whose mothers had jobs and those whose mothers did not work were 37 (67.9%) and 18 (32.1%), respectively. Food consumption with ordinary diets was normal in 23 students (41.1%) and the average frequency of snack intake and eating-out was determined to be twice a day (41 students, 73.2%) and once or twice per week (36 students, 64.3%), respectively. The most popular type of food consumed when eating-out was ‘fast foods’ in 28 students (50.0%). It was determined that on average, 39 students (69.6%) snacked between lunch and dinner time and 31 (55.4%) selected snacks based on information obtained through ‘mass media’. Analysis of the effects of nutrition education revealed an increase in the number of correct answers to the question ‘foods with high nutritional value are high calorie foods,’ with significant difference, but not in other questionnaires. In addition, the correct information for calcium (p<.05), good dietary habits (p<.001), food poisoning (p<.05), and six groups of nutrients in foods (p<.001) improved after nutrition education, with significant differences. As a result, the ratio of correct answers increased after nutrition education, with a significant difference (p<.001). After the education, the experimental group had a higher total score than the control group, with significant difference (p<.01).

This study investigates the effect of strategies-based English reading programs on reading proficiency and affective domains of underachieving elementary school students. Eight fifth-grade students were selected and assigned to either the phonics/vocabulary learning group or the vocabulary/sentence learning group for two hours a week for 16 weeks. To address the research questions, data were collected from four main sources: English reading tests, questionnaire surveys, students’ learning logs and in-depth interviews with the students. The results of the study revealed that the English reading programs had positive impact on the students’ understanding of the relationship between letters and sounds, word recognition ability, and sentence reading. As students accumulated successful reading experiences, their self-confidence, interest in reading, and class participation increased while anxiety decreased. The study also revealed that there were differences in using strategies among students in each group, with higher level students tending to use higher-dimensional strategies with more variety than less able students. In conclusion, the leveled English reading programs customized for underachievers appear to be effective in assisting underachievers in their English reading skills.

최근 웹과 스마트폰 앱이 갖는 장점을 활용한 컨텐츠가 속속 개발되고 있으나, 웹지도 이용실태에 대한 현황조사는 미흡한 실정이다. 이에 이 연구에서는 초등 사회과 지리교육에서 웹지도의 활용현황과 교사들의 요구를 파악하기 위한 조사를 수행하여 웹지도 활용교육이 나아가야 할 발전 방향을 모색해 본다. 연구자료는 설문조사와 면담을 통해 수집하였다. 분석결과, 교사들은 웹지도를 일상생활에 주로 사용하지만, 수업시간에도 웹지도는 초등 사회과 지리교육에서 지도의 원리 학습 및 적용에 활용되고 있었다. 주로 일반도와 위성영상지도를 활용하며 각 웹지도 사이트별 활용하는 지도의 유형에 선호도 차이를 보였다. 교사들은 웹지도에 대해 지명, 위치찾기 등에 만족하며 백과사전과 같은 지역정보, 지도에 나오는 지역의 사진, 동영상 등이 웹지도와 결합되어 제공되기를 희망하였다. 교실 IT 인프라 환경은 웹지도 활용의 장애요인이 되고 있으며, 교사들은 기능과 디자인면에서 교사와 학생의 조작, 변형, 활용이 용이한 웹지도 서비스의 요구를 드러냈다. 또 교사들의 경력과 사회과 교수 곤란도에 따라 웹지도에 대한 만족도와 활용에 있어 차이를 나타내므로 이를 고려한 정책적 지원이 마련되어야 할 것이다.

漢詩는 한문 문학 중 가장 아름다운 꽃이라 불린다. 따라서 학생들이 한시를 배울 때, 시의 내용 뿐 아니라 시의 아름다움까지 느낄 수 있도록 해야 한다. 이것은 학습자들이 직접 한시를 해석하고, 이해하고, 감상하는 실제적인 활동을 통해 획득될 수 있다.본 논문에서는 학습자들이 직접 한시를 감상하는 경험을 할 수 있게 하는 방법으로 ‘학습자 중심의 능동적 한시 감상 지도 방안’을 제안하였다. 단원의 도입부에 ‘감상을 위한 준비’ 단계를 통해 감상 태도를 정립하고 한시에 대한 기본 지식을 쌓는다. 개별 작품에 들어가서는 ‘도입’에서 동기 부여 및 시에 대한 배경 지식을 익히고, ‘漢詩 해석과 암송’ 단계에서 3차에 걸친 시 번역 및 해석과정을 거쳐 시에 대한 이해를 더한다. ‘육색사고모기법을 통한 漢詩 감상’단계에서는 본격적인 시 감상이 이루어진다. 시 속의 객관적 사실과 주관적 느낌, 긍정적 측면과 부정적 측면을 살펴보고, 이를 바탕으로 시 전체에 대해 종합적인 이해와 감상을 한다. ‘정리’ 단계에서는 앞서 이루어진 漢詩 감상 경험을 바탕으로 감상문을 쓴다. 일련의 활동을 통해 학습자들은 한시 텍스트 자체를 충분히 살펴보고 감상할 기회를 갖게 된다. 지속적인 토론과 발표 과정을 통해, 한시에 나타난 내용․시상의 전개방식․형식과 표현미 등 한시의 다양한 측변을 감상할 수 있는 안목을 지니게 되며, 자기의 감상으로 정리할 기회를 갖게 된다. 이를 통해 한시를 ‘비판적으로 이해하고 심미적으로 향유할 수 있는’ 독자로 성장할 수 있는 구체적인 경험을 얻게 된다.

이 연구는 스마트폰 사용이 많아지고 스마트폰 중독이라는 말이 생겨날 정도로 학생들이 스마트폰에 빠지는 것을 지켜보면서 모바일 역기능을 해소하기 위하여 학생들에게 알려주는 프로그램을 개발하려고 하였다. 다양한 모바일 기기를 통해 시간과 장소의 제한 없이 원하는 사람과 소통하고 각종 매체로부터 다양한 미디어 정보에 쉽게 접근할 수 있어 편리하기는 하지만 이에 따른 역기능 또한 함께 대두되고 있다. 우리 아이들은 스마트폰으로 원하는 정보에 쉽게 접근할 수 있고, 카카오톡과 같은 채팅 애플리케이션이 무분별하게 쏟아지면서 이들을 이용한 사이버 연애 및 성범죄의 온상이 되고 있으며 스마트폰이 가지는 매력 때문에 아이들이 매료되어 중독이라 할 정도로 스마트폰을 과다하게 사용하고 있다. 이에 본 연구자는 현재 아이들이 모바일기기로 인하여 기존에 경험하지 못한 부작용을 예방하고 새로운 정보통신 윤리관의 정립 및 교육적인 측면에서 모바일 역기능 해소 프로그램 개발을 통한 학습자 정보통신 윤리의식 소양 지도를 모색하게 되었다.

본 연구의 목적은 대학교양무용 참가 대학생이 지각한 지도행동과 흥미 및 학습태도의 관계를 규명하여 참가학생들의 흥미를 유도하고 학습효율성을 높이는데 필요한 유용한 정보를 제공하는 데 그 목적이 있다. 이러한 연구의 목적을 달성하기 위하여 2013년 10월 4일부터 30일까지 J지역과 K지역에 소재되어 있는 J대학, P대학, S대학 교양무용참가 대학생을 모집단으로 선정하였으 며 표집방법은 편의표본추출법(convenient sampling method)을 이용하였다. 설문지 작성은 자기 평가기입법을 통해 설문지를 작성하도록 하였다. 최초 230명을 대상으로 설문지를 배포하여 자료 가 누락되거나 5문항 이상 응답하지 않았고 10문항이상 동일한 응답을 반복한 46부를 제외하여 총 184부가 최종분석에 사용되었다. 본 연구에서 얻은 결론을 다음과 같이 제시하고자 한다. 첫째, 교양무용참가 대학생이 지각한 지도행동은 참가 대학생의 흥미에 유의한 영향을 미치는 것으로 나타났다. 둘째, 교양무용참가 대학생의 흥미는 학습태도에 유의한 영향을 미치는 것으로 나타났다. 셋째, 교양무용참가 대학생이 지각한 지도행동은 참가 대학생의 학습태도에 유의한 영향을 미치는 영향을 미치는 것으로 나타났다.

이 연구는 지도경연대회들을 탐구하여 지도그리기의 지도학습과의 관련성을 파악하고, 지리교육에서 지도그리기의 활용방안을 제안한다. 이를 위해 한국과 일본의 어린이 지도경연대회들과 국제지도학회의 바버라 페추닉 지도경연대회의 취지와 운영 방식 뿐만 아니라, 수상작품들을 비교했다. 한국의 지도경연대회는 짧은 역사속에서도 주제가 마을을 그리는 그림지도에서 ‘세계속의 대한민국’을 창의적이고 예술적으로 표현한 지도로 변화했다. 이는 지도의 원리와 기호 사용의 이해를 넘어 지도의 상징성과 예술성을 강조하는 쪽으로 지도학습이 변화된 것이다. 일본의 지도경연대회가 환경지도 그리기 활동을 지리 탐구와 병행하는 점과 바버라 페추닉 지도경연대회가 주제별로 작품을 모집하고 이의 교육적 활용을 중시하는 점은 향후 한국의 지도경연대회의 운영 방향과 지도학습에서 지도그리기의 활용 방안을 수립하는데 시사하는 바가 크다.

The purpose of this study is to explore, describe and analyze the English education process of underachieving elementary school students. To this end, qualitative research methods were used. The analyses produce two themes: positive and negative English learning experiences. Students are motivated when teachers are friendly and give them positive responses. Teaching materials including interesting games give more motivation to students. Content coverage for one period should be moderate for students to achieve. Students are disengaged in the classes when they come to supplementary classes against their will, and the content is above their level. Environmentally, parental indifference is translated into student’s indifference to the study. A rushing environment to cover too many units of materials makes them frustrated moving on without grasping what’s being taught. In conclusion, a careful understanding about managing time, learning environment, teaching materials and rapport formation between students and teachers are found to be necessary in the underachieving elementary school student's English education.

본 연구의 목적은 지구과학 교사 연구 모임에 참여하고 있는 교사의 야외 지질 학습에 관한 인식과 실행을 조사하는 것이다. 연구 참여자는 은대리 지역의 야외 지질 학습에 지도 교사로 참여한 지구과학 교사 4명이다. 자료 수집은 야외 지질 학습 수업 관찰 및 녹화, 학생들과 교사들을 대상으로 한 반구조화된 심층면담, 야외 지질 학습 수업 자료 및 학생 보고서 등을 통해 이루어졌으며, 야외 지질 학습 수업 및 면담 자료를 전사한 후 질적 분석을 하였다. 연구 결과에 의하면 연구 참여 교사들은 대체로 야외 지질 학습의 목적으로 심미적인 측면을 중요시하고 있었고, 실제 연구 참여 교사들의 야외 수업에서 학생들이 과학적 탐구에 참여할 수 있는 다양한 교수 방법과 전략이 활용되고 있었지만, 각 관찰 지점에서의 제한된 시간 등으로 인하여 학생들의 활동보다는 교사의 설명이 더 많은 야외 강의의 측면이 보였다. 연구 참여 교사들은 교사 연구 모임과 야외 지질 답사 참가, 대학원 진학 등을 통해 야외 지질 학습 지도를 위한 전문성 개발에 계속적인 노력을 해오고 있었다.

The present study investigates the effects of teaching activity-based integrative reading and writing on the amelioration of written language in the elementary school classroom. This study was conducted during the first semester in 2003. The subjects were 160, 6th year elementary school students. They were divided into two groups, control and experimental. Both the control group and the experimental group were composed of 80 students each. Each group was divided into three levels: high, intermediate, and low, on the basis of a diagnostic evaluation. All the subjects of the experimental group were integratively taught reading and writing of the English alphabet, words, phrases, sentences, and context, according to their level. All the subjects of the control group were discretely taught reading and writing according to their curriculum and level. They were also given a questionnaire of affective and psychomotor domains. Statistical analyses were performed to determine: (a) the difference of the control and experimental groups, (b) the difference between the control and experimental groups, (c) the difference of their level (high, intermediate, and low) of the control and experimental groups on reading and writing in the pre- and post- achievement tests, and (d) the difference of the level of the control and experimental groups on the affective and psychomotor domains such as interest, self-confidence, understanding, participation, and motivation of reading and writing in the pre- and post- achievement tests. The results of this study reveal that significantly higher scores on the written language were obtained in the experimental group. The difference between the control group and the experimental group was not significant at the beginning of the term. However, the difference was significant at the end of the term. It was also found that in the experimental group, interest was improved at the intermediate level. Self-confidence and understanding were improved at the intermediate and low levels, and participation was improved at the low level. It is recommended that researchers and teachers develop integrative materials of reading and writing more widely according to the level.
