Analogical thinking is a problem-solving strategy to use a familiar problem (or base analog) to solve a novel problem of the same type (the target problem). The purpose of this study is to provide new insight into geography teaching and learning by connecting cognitive science research on analogical thinking with issues of geography education and suggest that teaching with analogies can be a productive instructional strategy for geography. In this study, using the various examples of analogical thinking used in geography we defined analogical thinking, addressed the theoretical models on analogical transfer, and discussed conditions that make an effective analogical transfer. The major research findings include the following: a) the spatial analogy, indicating skills to find places that may be far apart but have similar locations, and therefore have other similar conditions and/or connections, can provide a useful way to design contents for place learning; b) representational transfer, specifying a common representation for two problems, can play a key role in solving geographic problems requiring data visualization and spatialization processes; and c) either asking learners to compare/analyze similar examples sharing common structure or providing them examples bridging the gap between concrete, real-life phenomena and the ideas and models can contribute to learning in geographic concepts and skills. The spatial analogy requiring both geographic content knowledge and visual/spatial thinking has the potential to become a content-specific problem-solving strategy. We ended with recommendations for future research on analogy that is important in geography education.

Physical disturbance, which induces a lack of flow rate, frequently occurs in freshwater ecosystem. Due to this, it is required to provide a new fish shelter to resolve. We installed a pilot scale test-bed to scrutinize the relationship between water level and the influence of fish shelter. The proposed ADP (artificial deep pool) is a fish shelter which composed of concrete materials. From the monitoring results in test-bed, it was observed that the population of fish was the highest at the 0.5 m in depth from the water level of experimental pond. But it was more appropriate for shallow water level (<0.3 m) to conserve the total number of fish by increasing the number per unit area despite of lower inner temperature and DO than outer environment. Therefore, inner of ADP was more efficient lentic system for fish to live due to higher WCS, OS, SS, and TS. In addition, there was a relative abundance of WCS fish species such as Acheilognathus koreensis (A. koreensis), Carassius carassius (C. carassius). Considered these results, it is suggested that ADP is appropriate to use for fish shelter and habitat for the fishes in lentic ecosystem.

This study proposed more reasonable prediction models on compressive strength and carbonation of concrete structure and developed a more effective tunnel safety diagnosis and maintenance method through field application of the proposed prediction models. For this study, the Seoul Metro's Line 1 through Line 4 were selected as target structures because they were built more than 30 years ago and have accumulated numerous diagnosis and maintenance data for about 15 years. As a result of the analysis of compressive strength and carbonation, we were able to draw prediction models with accuracy of more than 80% and confirmed the prediction model's reliability by comparing it with the existing models. We've also confirmed field suitability of the prediction models by applying field, the average error of an estimate on compressive strength and carbonation depth was about 20%, which showed an accuracy of more than 80%. We developed a more effective maintenance method using durability prediction Map before field inspection. With the durability prediction Map, diagnostic engineers and structure managers can easily detect the vulnerable points, which might have failed to reach the standard of designed strength or have a high probability of corrosion due to carbonation, therefore, it is expected to make it possible for them to diagnose and maintain tunnels more effectively and efficiently.

This study was to look into the press policy and the related activities performed by North Korea in the South during the Korean War and to evaluate them. In order to understand the concrete contents of the activities and their characteristics, the two representative newspapers published in the South by North Korea at that times - the Chosuninmin Bo and the Haebang Ilbo - were reviewed and analyzed. North Korea operated broadcasting and started newspapers just after the possession of Seoul. and also performed various positive press activities - such as the distribution of the newspapers and periodicals of North Korea and U.S.S.R., putting the movies on the screen, and founding the weekly, etc. But the target of all the media were the same. It aimed to support Kim Il-Sung's scheme which intended to carry out the war successfully and to make the South under occupation Communism System by introducing the Northern law and system. The two newspapers, as agent of power, made only such a role to agitate and exaggerate the false things with unrealistic optimism. They intended to ideologically mobilize the South people and to affect on their perspectives and acts. However the media including the two newspapers being operated in the South during the war had not got the faith or the good response from the South people as an audience. Most of South Koreans were tired with their endless and one-sided propaganda, agitation and ideological enlightenment. It could therefore be evaluated that the press activities by North Korea in the South during the Korean War resulted with many limitations in ideologically organizing and mobilizing the South Koreans.

A theme park is a complex space, in which held is a performance & exhibition event created to make visitors feel fun and a deep impression through a certain theme. Recently, local governments are increasingly planning for theme parks with the aim of local economy revitalization. Accordingly, this paper set up a development model for a Korean culture theme park after deducting success factors for creating a successful theme park through the case of Korean culture theme park. To be concrete, this paper deducted the success factors through literature research and case research as follows: Setting of themes having identity and consistency; programs that can give fun and a deep impression; convenient support facilities reflecting customers' needs; differentiated marketing for progress in customer attraction power; location linked with cultural resources around a theme park and a space for communicating a message; privately-initiated project promotion and the main body of operation; target setting consequent on market segmentation, and demand forecast, etc. A theme park cannot be successfully operated to contribute to local economy revitalization until such success factors should be closely linked and harmonized with each other. In addition, in order for a theme park to make a continued growth, it's required that problems occurring at the operational stage should be endlessly improved, and contents strengthening should be continuously done in line with circumstances of the times and viewers' eye level.

This study is aimed at enhancing the prosocial behaviors and the positive peer play interaction of young children with developmental delays. Three children with developmental delays and three students without developmental delays who were 4-year-old students in an inclusive classroom were selected. Their homeroom teacher carried out the program with a small group of 6 children totaling 21 sessions over 3 months. The major results of this study were as follows: First, the result of both the observer and the parents' test after the program showed that the small group made positive changes on prosocial behaviors. In addition the frequency of target behaviors increased during the intervention. Second, the result of both the observer and the parents' test after the program showed that positive peer play interaction increased in the small group. Moreover the negative peer play interaction such as play disturbance and play isolation decreased. In conclusion, the thematic fantasy play program is useful for an inclusive classroom, and can be a concrete method to support inclusive education and childcare.

The study is to examine the actual conditions and problems of educational welfare which is a part of social welfare and to offer its future directions and things to do. First of all, education has been considered to be part of social welfare in developed countries for a long time and it has been used the same as school educational welfare. These days Korea is confronted with increasing needs of educational welfare caused by emphasis of manpower, appearance of new poor class after IMF, handing down poverty to their children, absence of public education and educational fever, stress of life long learning and extending needs of students' social welfare service. In advanced countries compared to Korea, people perceive education as an equal opportunity. To reach this thesis, various efforts have been making in terms of manpower development such as reform of related laws, financial and official support, offering of parental skills and protecting children for the disadvantaged, dispatching school social workers and overall life improvement. The subjects and age of educational welfare are also diverse ranging from poor families and pre school children to general public and adults. On the other hand, Korea lacks related laws and financial support that are supposed to enforce educational welfare systematically. Also integrated and professional services are not often available due to the lack of cooperation between related agencies. Therefore, government's role and responsibility should be defined clearly in the future directions of educational welfare in Korea. For this, it is needed to establish related laws and build a concrete financial and executive interrelationship. Also every person should be a target of educational welfare putting priorities on the disadvantaged. A lot of efforts should be made to achieve things mentioned above. Multi-dimensional approach intertwined with education, welfare and labour, establishment of cooperation system between related agencies, reinforcement of life long learning, extension of free education including infants and toddlers, and offering financial support to the poor are a few among these efforts. Finally, institutionalization of school social welfare and improvement school facilities are strongly recommended to get to the right track of educational welfare.

In this study, we analyzed the analogies in the chemistry domain of 27 middle school science textbooks and 8 high school chemistry textbooks developed under the 2009 Revised National Curriculum. A total of 284 analogies (science, 143; chemistry, 141) were identified from the textbooks, which means that 8.11 analogies (science, 5.3; chemistry, 17.6) per textbook and 0.68 analogy (science, 0.66; chemistry, 0.70) per 10 pages were used on average. Compared with previous curricula that the number of analogies gradually increased, the use of analogy was found to be somewhat decreased in the 2009 Revised National Curriculum. The number of analogies found in each textbook considerably varied depending on course, unit, and publishing company. One hundred ninety one different kinds of analogies were used, among which 38(19.9%) were used over twice. Further analyses of the types of analogies indicated that verbal and pictorial analogy, analogy with abstract target and concrete analog, and enriched analogy were frequently used. However, the term 'analogy' and the description about the limitation of the analogy were rarely mentioned. Artificial analogy, teacher-centered analogy, and analogy with low systematicity were also found to be frequently used. Educational implications of these findings are discussed.

In this paper, we present algorithm-level techniques for energy-efficient design at the algorithm level using FPGAs. We then use these techniques to create energy-efficient designs for two signal processing kernel applications: fast Fourier transform(FFT) and matrix multiplication. We evaluate the performance, in terms of both latency and energy efficiency, of FPGAs in performing these tasks. Using a Xilinx Virtex-II as the target FPGA, we compare the performance of our designs to those from the Xilinx library as well as to conventional algorithms run on the PowerPC core embedded in the Virtex-II Pro and the Texas Instruments TMS320C6415. Our evaluations are done both through estimation based on energy and latency equations on high-level and through low-level simulation. For FFT, our designs dissipated an average of $50\%$ less energy than the design from the Xilinx library and $56\%$ less than the DSP. Our designs showed an EAT factor of 10 times improvement over the embedded processor. These results provide a concrete evidence to substantiate the idea that FPGAs can outperform DSPs and embedded processors in signal processing. Further, they show that PFGAs can achieve this performance while still dissipating less energy than the other two types of devices.
