The Baekje Gilt-bronze Incense Burner which was excavated in an ancient temple site in Neungsan-ri, within the City wall of Buyeo-Gun on 23rd December 1993, was a quintessence of the Bakje Arts that people could not have imagined until that time. The Baekje Gilt-bronze Incense Burner transcended 1400 years of time and space. The censer that finally came up to us delivered a kind of a powerful message to us. The power was so strong and mysterious that as if an ancestor who had been sleeping in the grave with a great silent had woken up and become alive to tell us something very precious. Baekje Gilt-bronze Incense Burner, unlike any other existing artifacts, might have a possibility that could provide an insight of the ancients' psych who once lived on our land. This kind of view from several archaeologists, therefore, made our hearts be filled with excitement and flutter. We call 21st century as an era of culture. This era requests that the culture needs to be ethnical but the culture also needs to go beyond that ethnic. In other words, a culture without an ethnic cannot exist, and a culture that puts an ethnic the very first before any other things cannot exist as well. Regaining our identities first and then embracing and harmonizing various cultures can be an wise way overcoming above problem. Hence, through this study, I intend to recognize characteristic of plasticity for Baekje Gilt-bronze Incense Burner, understand the world of Baekje people's spirit and thus provide an opportunity to shed new light on the Baekje Arts. By doing so, I would like to publicize a metal craft of Korea to the world. I also try to seek for an identity of Korea's craft culture which is receding and find a direction for the Korea's craft.

This study was presented to effect of prescribed burning to the avian fauna and was conducted from March to October 2007 in Sihwa grassland, Gyeonggi-do, Korea. Prescribed burning was conducted at Sihwa grassland of Songjeong-ri Mado-myeon, Hwaseong city from 28th February to 1 st March 2007. Thirty birds species were observed and sum of the maximum count was 181 individuals at the prescribed burning area for all survey time. Observed species was 24 species and sum of the maximum count was 154 individuals on the unburned area. Number of species and sum of the maximum count at the prescribed burning area was greater than unburned area. There is no differences in the dominant species between prescribed and unburned area. Average number of species, number of individuals, species diversity and species richness of the prescribed burning area were greater than unburned area in early stage (from March to June) after prescribed burning. Community indices in burned area during early season were different with unburned area by prediscribed burning. However, the indices had became similar between burned and unburned area as time goes by. Disturbance by prescribed burning created new habitat and feeding site temporarily for the avian species in grassland. We would suggest that prescribed burning is most effective method to maintain grassland ecosystem from the invading bush or tree and periodical prescribed burning is a good method to preserve and manage the grassland ecosystem.

This paper discusses 5G IOT, Augmented Reality, Cloud Computing, Big Data, Future Autonomous Driving Vehicle technology, and presents 5G utilization of Pyeongchang Winter Olympic Games and Jeju Smart City model. The reason is that 5G is the main artery of the 4th industry.5G is the fourth industrial aorta because 5G is the core infrastructure of the fourth industrial revolution. In order for the AI, autonomous vehicle, VR / AR, and Internet (IoT) era to take off, data must be transmitted several times faster and more securely than before. For example, if you send a stop signal to LTE, which is a communication technology, to a remote autonomous vehicle, it takes a hundredth of a second. It seems to be fairly fast, but if you run at 100km / h, you can not guarantee safety because the car moves 30cm until it stops. 5G is more than 20 gigabits per second (Gbps), about 40 times faster than current LTE. Theoretically, the vehicle can be set up within 1 cm. 5G not only connects 1 million Internet (IoT) devices within a radius of 1 kilometer, but also has a speed delay of less than 0.001 sec. Steve Mollenkov, chief executive officer of Qualcomm, the world's largest maker of smartphones, said, "5G is a key element and innovative technology that will connect the future." With 5G commercialization, there will be an economic effect of 12 trillion dollars in 2035 and 22 million new jobs We can expect to see the effect of creation.

If we, as educators, want to put students at the center of learning in science classroom, we must let students express their voices and exercise authority. To do this, we developed a classroom activity about 'Making a pet poster', and then we explored how elementary school students perceived their roles and expressed their authority during this activity. Fourth grade students from an elementary school in the city of Seoul participated in the activity, which was videotaped and recorded. We found that students expressed their epistemic authority differently in small group activities and in whole group discussions. In small group activities, they desired to show their authority as "pet experts" by using and selecting various resources from their everyday lives and transforming those resources into suitable forms in public spaces. Meanwhile, in whole group discussions, participants were classified as either presenters or audience members to verify their authority in regard to the pet poster activity; presenters desired to achieve recognition as "pet experts," and audience members assessed the presenters as "testers." In addition, they expressed authority as teachers by leading the whole group discussions. Based on these findings, this paper suggests the implications for new educational strategies to foster a student-centered learning environment.

Global companies regard the conditions of a location as one of the most crucial factors to assess the competitiveness of ports and the port hinterland, as well as emphasize creation of throughput and the importance of value added logistics in the hinterland under diffusing Supply Chain Management(SCM). This study deals with the evaluation of competitiveness in 7 hinterlands and the establishment of assessment model in hinterland. This study analyzes the importance of factors for the port hinterland competitiveness using AHP method. As a result, logistics factor, accounting for 62.3%, is shown as the relative more important factor, followed by hinterland's economy factors(27.3%) and city/policy factor(10.4%). The result implicates that measures to activate logistics factors with relatively high importance are essentially needed in order to improve the competitiveness of the hinterland of Busan New Port. Especially, it is needed to establish service routes of the port and air networks and to expand infrastructure for support. This study also assesses the competitiveness of hinterlands for the seven domestic and foreign ports based on importance of assessment factors for the hinterland competitiveness using AHP analysis. Busan(3.903) is ranked fourth behind Singapore(4.570), Hong Kong(4.357) and Shanghai(4.042) in assessment.

A survey showed that the public perception of the shipping industry's overall image and economic role was relatively positive. The survey revealed that public perception was mixed with respect to the multifaceted role of the shipping industry. Based on the results of this survey, this paper proposes three approaches to improving the public perception of the shipping industry. The organization contact approach includes establishing shipping institutes for city people, holding various events targeted at the public, establishing a shipping memorial hall, developing a shipping-related culture and tourism, reinventing the image of the shipping industry through a shipping-culture movement, and creating new views of the shipping industry by conducting formal education. The goods and services contact approach includes building a brand image for shipping services, providing B2C services, utilizing the national image for the shipping industry, and participating in international cooperation projects. The text contact approach includes B2B advertising, advertisements focused on the national economic and multifaceted role of the shipping industry, package advertisements for the shipping industry and related industries, the Internet and high-technology media, government-initiated PR activities regarding the multifaceted role of the shipping industry, and funding for advertising the shipping industry.

An urban drainage system consists of two major systems : flood drainage facilities and operating practices. The facilities are composed of sewer networks, gates, and pumping stations and the operating practice consists of pump or gate operation. Then, a real time simulation system which is able to simulate urban runoff and the pump operation and to consider the backwater effect is required to operate efficiently the pump. With this system, the efficient pump operating rule can be developed to diminish the possible flood damage on urban areas. In this study, a real time simulation system was developed using the SWMM 5.0 DLL and Visual Basic 6.0 equipped with EXCEL. Also, for developing efficient pump operating Rules, two new Rules were suggested. The first Rule is designed to operate pumps considering the condition of sewer networks such as depths of each junction. The second is to discharge all the amount of inflow at each time step. Results obtained by those Rules were compared with one by the current pump operating Rule which is able to consider only the depth of the retard basin. The developed model was applied to Joonggok retard basin and verified their applicability.

Recently climate change and increase of surface runoff caused the urban flooding. Traditional way of dealing with urban flooding has been to increase the sewer capacity or construction of pumping stations, however, it is practically almost impossible because of time, money and traffic problems. Multipurpose DRMS (Decentralized Rainwater Management System) is a new paradigm proposed and recommended by NEMA (National Emergency Management Agency) for both flood control and water conservation. Suwon City has already enacted the ordinance on sound water cycle management by DRMS. In this study, a flood prone area in Suwon is selected and analysis of DRMS has been made using XP-SWMM for different scenarios of RT installation with same total rainwater tank volume and location. Installing one rainwater tank of 3,000$m^3$ can reduce the peak flow rate by 15.5%. Installing six rainwater tanks of 500$m^3$ volume in the area can reduce the peak flow rate by 28%. Three tanks which is concentrated in the middle region can reduce peak rate more than evenly distributed tanks. The method and results found from this study can be used for the design and performance prediction of DRMS at a flood prone area by supplementing the existing sewer system without increase of the sewer capacity.

The purpose of this study was to develop and apply a Korean language education program based on multiple intelligences in a bid to foster the multiple intelligences, self-efficacy and achievement motivation of elementary schoolers in regular language arts class. It's basically meant to create the educational conditions for every child to exert his or her abilities. Two research questions were posed: 1. What should be the objectives, content and teaching-learning methods of a Korean language education program based on multiple intelligences? 2. What effect does a Korean education program based on multiple intelligences have on children's multiple intelligences, self-efficacy and achievement motivation? The subjects in this study were 58 Students in two different third-grade classes in M elementary school in the city of Daejeon. A Korean language education program based on multiple intelligences was implemented during a 4month period of time, and an inclusive approach of multiple intelligences and cooperative learning were applied. The major findings of the study were as follows: First, in order to develop a Korean education program based on multiple intelligences, the kinds of themes that could cover multiple intelligences in an inclusive way were selected in consideration of the learning objectives of the major units of a third-grade language arts textbook(second semester) of the 7th national elementary language arts curriculum. And then an inclusive Korean education program was prepared, which consisted of four stages: problem awareness, problem-solving planning, problem solving, and reflection/application/development. Second, the Korean education program based on multiple intelligences had a positive effect on the children's multiple intelligences, self-efficacy and achievement motivation and suggested some of new directions for school education that typically stressed linguistic and logical-mathematical intelligences only.
