우리나라의 해안지역은 경제개발과 함께 많은 변화를 겪어왔으며 인간활동의 간섭을 많이 받아왔다. 이 지역은 단기간 토지 이용에 많은 변화가 있었으며, 이에 따른 지형 변화가 발생해 왔다. 이에 본 연구는 시기별 원격탐사 영상을 이용하여 영광군 백수읍과 염산면 일대의 변화를 구체적으로 탐지하고자 하였다. 연구지역인 영광군 백수읍과 염산면은 서해안에 위치한 지역으로, 연구 분석에는 1967년, 1989년, 2000년, 2009년의 원격탐사 데이터와 1918년 지형도가 사용되었다. 분석결과 1918~2009년 동안 백수읍, 염산면 일대의 면적은 크게 증가하였으며, 특히 농경지, 양어장, 염전의 면적이 증가하였다. 또한 해안사구, 불갑천 등의 지형도 변화하였다. 이러한 변화는 주로 정부주도의 지역개발사업의 결과로 보이며, 2000년대 이전에 많이 이루어진 것으로 나타났다. 본 연구는 영광군 해안지역의 개발 및 변화 과정을 파악하는 데 중요한 자료로 활용될 수 있을 것으로 기대된다. Coastal areas of Korea have undergone many changes over the years with economic development. The areas were affected by human activities and were changed in a short period of time. Along with this, the geomorphological features have changed giving rise to a variety of problems. In this study, the process of change was figured out using multi-temporal remote sensed data. Baeksu-eup and Yeomsan-myeon correspond to this study area, where these were faced with the Yellow Sea on the west. The remote sensed data on 1967, 1989, 2000, 2009 and topographical map on 1918 were used to study. As a result, these areas were expanded for 1918-2009. The areas in farmland, fish farm and salt pan particularly increase. Many topographies such as coastal sand dunes and streams have changed too. These changes were performed by economic development plan of the government, and most of that occurred before the 2000s. This study can contribute to understanding changing and development process of coastal areas in Younggwang-gun.

Silgyeong sansuhwa (Realistic landscape paintings) are drawn in Korea since 17th century. It has characteristics of more realistic description of landscape than painting from previous periods. Kim Hong Do’s ‘Haedong Myeongsan docheop (The album of paintings of famous mountains in Korea)’ has been recognized as fine example of realistic description of geomorphic landscapes. Kim Hong Do and Kim Eung hwan did official travel to Gwandong and Geumgangsan area by order of King Jeongjo in 1788. As a result of that travel they draw about 100 piece of landscape painting. About 60 pieces of the paintings are still remaining. These are open to public by Korea National Museum in 1996. 14 pieces of painting, Daegwanryeong and Gangneung, Gyeongpo-dae, Hohae-jeong, Gahak-jeong, Cheonggan-jeong, Mun-am, Mangyang-jeong, Wolsong-jeong, Neungpa-dae, Naksan-sa, Mureung-gye, Gyejo-gul, and Hyeonjong-am, are analysed in this study. Coastal depositional landforms, like lagoon, sand beach and spit or barriers, erosional forms, like sea stack, sea cliff and sea cave, depicted in the paintings are analysed. In addition, structural landforms, colluvial landform and bedrock incision form by the running water in mountain area were analysed and weathered forms of granite and excursion to karst cave also discussed. It is found that sea arch in the printing destroyed since 1788, though exact position and reason is still unknown. There are strong need for discovery and identification of geomorphic landscape resources, for applied geomorphological studies and for prepare educational materials for non-face-to-face education. It also be emphasized that it can be used of the course work materials for future education using augmented reality and virtual reality technology.

In the southeastern part of the Korean Peninsula, the Yangsan Fault, an active fault zone, has developed. Many earthquakes occur around these faults, and the possibility of earthquakes occurring along the branch faults is being discussed. On the other hand, the Yeongdeok Fault is reported in Yeongdeok-gun, which is the northern part of the Yangsan fault. In this study, goemorphic characteristics of a set faults found on the outcrop of the gentle slope of the coast of Byeonggok-myeon were analyzed and granulometric and geochemical characteristics of sediments and other materials, including fault gouges were analyzed. The outcrop of Byeonggok-myeon is the part of the fault core and can be divided into two parts. Theses fault are formed on the upper part of the Mesozoic bedrock and the tertiary sedimentary layer of red sand-supported clasts are covered in several sedimentary units. The faults were normal fault sets, and a number of vertical cracks were developed, and glossy surfaces were observed in the fault area. It appears that these faults have occurred after alluvial deposition had been formed. In the case of samples from fault gouges, there were differences in particle size and geochemical characteristics from the surrounding area.

As part of further study on Gwangseungri coastal deposits which occurred at 10 ~ 15m above sea level and was analyzed as palaeo-coastal flood-type sediments, six burial ages of six additional samples from the two cross sections (KST1 and, KST2) near to the points of the past study were estimated and the geochemical analysis was performed. Further investigation on the cross section KST1 revealed a reversal of the burial age at the bottom of the section which was identified as palaeo-flooding sediments and supposed to have been buried about 350 years ago. At the lower part of the KST1, the burial age of the sediment layer was estimated to be 3,800 years. The lower part of KST2 sediments was identified as sediments that was formed about 6,600 years ago and about 20,000 years ago. Considering the inclination of the sediment layers, the coastal flooding sediments reported to have formed 700 years ago in the previous study are located at the top and the KST1 section analyzed in this study seemed to be connected to the lower part. The chemical analysis showed that the relationship between these layers was not continuous but had a discontinuous characteristic influenced by a specific event, and the chemical composition also showed a rapid change. If we judge these together, the lowest part of Gwangseungri sediment layer seemed to have formed during the last glacial period but it was hard to find its origins clearly. On top of this layer, a fine sediment layer containing gravels was also formed. It seemed that sedimentation did not occur continuously, but was affected by temporary events in such a way that after a sediment layer was formed, it stopped. Since then, a coastal flooding event occurred about 700 years ago, and part of flooded sediments accumulated in the rear slope. After that, when a flood layer including additional granular materials about 350 years ago was formed, sedimentation along the slope seemed to have occurred.

The granulometric characteristics and chemical composition of the samples from the Bukpyeong myeon, Hainam gun, Jeollanam do were analyzed in this study. The samples were collected from the outcrop of coastal area where the height is about 30m. The burial age of the sediments also estimated by OSL(Optically Stimulated Luminescence) method. The origin and forming processes of the samples are not clear in this stage as limited number of evidences can be found. However it is suggested that the samples are not aeolian deposits originated from chinese loess by the chemical analysis. The mean diameter of samples were 5~6φ(silt) and are increased slightly downwards. The samples also well sorted. The samples have been heavily weathered by the chemical alteration index. The value of CIA increase downward rapidly at the upper part of outcrop, then stabilized afterwards. The vertical concentration changes ratio of cations varies; Si increases downwards while Fe, Ti, K and Mg decrease. There are fluctuation in concentration ratio of Na and Ca with increasing depth. The burial age of sample from upper part are estimated as 104.52±4.45ka BP, while that of lower part are 136.10±6.52ka BP, and they fall in to last part of MS6. The deposition rate for this site is found about 0.017mm/year. The uplift rate of the site is supposed to be 0.24~0.26m/ka with assumption of palaeo-sea level of +6m. However the origin of the sediment deposits should be explored and cleared.

With the number of foreigners residing in Korea exceeding 1 million, the need for policy responses that match the regional characteristics of foreigners living in the region is being emphasized. In this study, the distribution of foreigners by gender, nationality, and status of residence, and population characteristics by age in Chungcheongbuk-do and Cheongju-si were analyzed using official statistical data for June 2020 and June 2021. The proportion of foreigners in Chungcheongbuk-do is about 2.2%. Even within Chungcheongbuk-do, there is a big difference between cities and counties, and a significant number of foreigners live in Cheongju, Eumseong-gun, Jincheon-gun, and Chungju-si. In Eumseong-gun and Jincheon-gun, foreigners account for 8.93% and 6.38% of the total population. There are large regional differences in status of residence and structure by age, and the proportion of workers is high in industrial areas, forming a group residential area. In particular, in the Bongmyeong-dong area of Cheongju-si, foreigners from the former Soviet Union and neighboring countries reside intensively. It seems that various efforts at the local government level are needed for educational and cultural support and exchanges and cooperation with Koreans for these collective residential areas.

Igil-ri Wetland, a riverine wetland, has been developed in Dongsong-eup, Cheorwon-gun, Gangwon-do, Korea. The wetland area is the upstream part of the Hantangang river, and is located within the Northern Area of the Civilian Control Line. Because of accessibility problems, geomorphological and geological investigations of the Igil-ri Wetland have been limitedly conducted. The purpose of this study is to understand the geomorphological and geological characteristics, focusing on the fluvial landforms in the Igil-ri Wetland area. In the Igil-ri wetland area, basalt and granite landforms are distributed, and around the Hantangang river, basalt-based river terraces, floodplains, and steptoe are developed. The Igil-ri area is generally based on basalt layers, above it, fluvial sediment layers appear. It is estimated that basalt lava has filled valleys from the downstream. In addition, sand bars and gravel bars are repeatedly distributed on river bed, and chute channel and braided channel are formed in the Hantangang river. A large amount of sediments were likely transported from various tributaries and upstream, centered on the Gimhwa Namdaecheon Stream. Currently, Igil-ri wetland area has little anthropogenic influence due to military factors, so it not only functions as a habitat for many animals and plants, but also has high value as a place for geomorphology learning. Therefore, it seems necessary to discuss the designation of ecological wetland protection area. This study will help as basic data for designating the Igil-ri wetland as an ecological wetland protected area.

The relationship between climatic factors of election day and turnout rates based on the results of previous presidential elections, parliamentary elections, and local elections are examined in this study. It was found that temperature and cloudiness were not related to the turnout rate. In the case of precipitation, the turnout rate on a rainy (or snowy) day, but it was difficult to generalize the relationship between the two factors. In addition, there was no significant effect on the change of turnout by region or turnout by sex and age according to the presence of precipitation. It is difficult to see precipitation as beneficial for a specific political party. It can be concluded that the effect of weather on turnout in Korea is not so much, based on this study. However, since the amount of data is insufficient to examine the relationship between the two factors, it is necessary to deepen study in the future continuously.

신원정(Won Jeong Shin),김종연(Jong Yeon Kim) 충북대학교 교육개발연구소 2021 한국교육논총 Vol.42 No.3

코로나 바이러스의 확산으로 학생들의 학교 등교가 정지되거나 제한되면서 학교의 교실수업은 비상 비대면 수업으로 급격히 전환되었다. 이에 따라 교원들의 비대면 수업 역량의 중요성이 크게 부각되었으며, 특히 예비교원과 교원들에게 원격교육의 기능과 기법을 교육할 필요성은 더욱 강조되고 있다. 이에 본 연구에서는 비대면 수업 역량 강화와 관련된 제반 사항들을 살펴보고, 비대면 수업 모형을 제시하였다. 비대면 수업의 준비와 진행 과정을 비대면 교육 내용의 선정, 비대면 교육 자료의 제작, 비대면 수업용 미디어 형성, 비대면 전달의 단계로 구분하고 각 단계에서 필요한 기술과 장비 등을 소개하였으며, 각 단계에서 필요한 기술적 측면, 수업 내용과 기술의 결합 측면, 기타 고려 사항 등을 제시하였다. 또한해당 모형을 적용하여 예비 교원들의 비대면 교육 역량을 강화할 수 있는 수업 콘텐츠 사례를 제시하였다. 마지막으로 비대면 수업 콘텐츠에서의 저작권 문제, 수업 질 격차 해소, 비대면 수업을 위한 예비 교원 양성 시스템 구축 등과 같이 예비 교원 양성의 관점에서 비대면 수업에 대한 시사점과 향후 과제를 제시하였다. The COVID-19 pandemic has led to dramatic changes in school education. Classes were suspended or students were restricted from attending school, and classroom instruction shifted toward distance learning. Accordingly, teachers’ teaching abilities related to non-face-to-face education have become very important. In particular, there is a growing need for education on various non-contact methods for prospective and present teachers. Therefore, this study introduced the preparation and progress of non-face-to-face classes. It has five stages: selection of educational content, production of educational materials, making of educational materials, media production for non-face-to-face classes, and non-face-to-face delivery. This study introduces the necessary technologies and equipment required for each stage. In addition, we provide a case class that can strengthen the capacity of non-face-to-face teaching of pre-teachers. In addition, we discuss topics such as bridging gaps in class quality, copyright issues, and preparing teacher training systems for non-face-to-face education.

The purpose of this study was to investigate the physicochemical characteristics and formation age of sand dunes in the Okjukdong and Dajindong, Daecheong Island. As a result, most of the sand deposited in Okjukdong were composed of medium sized sand with moderately well sorted. The SiO2 and Al2O3 accounted for a very high proportion of these deposits. There were some differences in characteristics between the sands in the dune and beach, whereas similar characteristics were observed among the materials (OJ-B, OJ-C and OJ-D) in the dune. In case of Dajindong, heterogeneous geochemical characteristics were found in the lower point. It was estimated that this was due to the influence of Daejin-dong black beach. Age dating results showed that uncovered dunes in Okjukdong were deposited 0.44±0.02 ~ 0.50±0.02 ka, and sand deposits in Dajindong were formed 0.16±0.01 ~ 0.18±0.01 ka. In both Okjukdong and Dajindong, sand deposits estimated to be formed 70 years ago, therefore it can be estimated that sand movement was active throughout the area from about hundred years ago. In this study area, the growth of sand dunes has been active in recent several decades or hundred years. It seems that there were different regions where deposits predominated over time. The source of dune sand was also different from time to time. Since the windbreak forest was established, the natural growth of sand dunes was limited, and sand nourishment was carried out by period. Therefore, in order to protect and continuously utilize coastal sand dunes in Daecheong Island, it is necessary to prepare conservation plan.
