  • The purpose of this paper is to suggest a model for an English learning web-site using Korean folktales to stimulate the interest of beginners learning English, (elementary and early middle school ages) and suggest an integrated way of teaching 4 skills. The study first reviews the theoretical and historical backgrounds of storytelling using Korean folk tale, WBI (Web Based Learning), and learner-centered learning. Storytelling using Korean folk tale is an interactive way of teaching English through the use of words and actions from Korean traditional culture. The students can take pride in their own culture while learning a foreign language since they are familiar with the stories and the culture. Nowadays multicultural education is one of the big features of global education. Therefore there are benefits of studying English through Korean folktales. The websites can help students learn English ubiquitously with a learner-centered focus. For the study, we analyzed several digital English storytelling websites. The paper concludes that digital English story books need to improve their interactive ways of teaching for more effective learning. The authors created an integrated English learning website model using Korean folktales for beginners. We hope to introduce this type of learning through the website for higher level students in middle school. Further study should be conducted in order to make the websites more meaningful and useful for Korean students learning English.

  • This study was done to find out the correlation between manual palpitation and mechanical measurement and the possibility to produce the data using chest and abdominal Front Point(募穴). Followings are the results from the present study. 1. The maximal pressure felt by the patient was 10kgf/$cm^2$. 2. The maximal deformation felt by the patient was in the range of 6cm. 3. The modulus (index obtained by the division of maximal pressure and maximal deformation) was highly correlated with manual palpitation. 4. It was useful to classify two front points in the abdomen and chest when modulus is concerned. 5. When the index of elastic modulus are big and small enough, it is said excessiveness and deficiency(虛實), respectively. Overall, this study was able to find the possibility to quantify the traditional state of excessiveness and deficiency in the form of objected data.

  • This study was designed to survey the stress distributions and deflections which were derived from MEAW by the computer-aided three dimensional finite element analysis of teeth and surrounding bone composed of 2839 solid elements and 4621 nodes. MEAW model was also made using the 90 beam elements and the results were expressed by quantitative and visible ways. The findings of this study were as follows. 1 In case of vertical load on the MEAW there were extrusions of anterior teeth and upright effects of the posterior teeth. 2. Without applying the vertical elastics on the MEAW there were intrusions of anterior teeth, but relatively mild force was transmitted to the posterior teeth area. Torque forces were observed on the incisors and molars, and canine was intruded without torque. 3. The magnitudes of forces were different by the amounts of tip back bends of MEAW. 4. The displacements were in inverse proportion to the cross section areas of the wires according to the experiment using the 5 different size arch wires. 5. The difference of deflections between the MEAW and plain arch wire was not so big as the theoretical one but the deflections of MEAW were much more than the plain arch wire in every X, Y, Z direction.

  • This study progressed an investigation on the cause of the efflorescence phenomenon of bricks in Suwon Hwaseong Fortress, which is designated as a UNESCO World Heritage by using diverse scientific analyses. The samples were taken in Hwaseong and analyzed using XRD and SEM-EDS for the material identification of efflorescence. We observed under a polarizing microscope and measured absorption factors for the basic investigation for traditional bricks. As a result of material identification, soluble salt($Na_2SO_4$, $KNO_3$) and insoluble salt($CaCO_3$) were detected. There was no big difference between original bricks and repaired bricks under the polarizing microscope. However, in terms of the water absorption rate, bricks which were used for repair nowadays showed low water absorption rate(1%). In conclusion, soluble salt and insoluble salt appeared due to an effect of an air pollution and joint mortar. Soluble salt was removed in the rainy season, but insoluble salt was not removed. As a result of the efficiency and safety tests for chemicals removing efflorescence, chemical E is likely to be the suitable chemicals for the efflorescence phenomenon of traditional bricks in Suwon Hwaseong Fortress. In the future, consideration whether the use of lime is available or not should be studied through comprehensive researches including repair work, construction work and the environment factor with lime. Also, physical, chemical identifications of repairing bricks will be required.

  • Recently, many TV restaurant programs become popular, and TV restaurant programs have a big impact on Korean restaurant consumers. The purpose of this study was to understand the effects of information attributes in Korean TV restaurant review programs food service customer's empathy, attitudes and visit intention. Based on a total of 254 samples obtained from the empirical research, this study reviewed the reliability and fitness of the research model using the Amos program. The hypothesized relationships in the model were tested simultaneously by using structural equation model (SEM). SEM showed that the beneficialness (${\beta}=.187$, p<.01), amusement (${\beta}=.427$, p<.001) and vividness (${\beta}=.243$, p<.01) showed positive significant effects on customer's empathy. Customer's empathy had a positive significant effect on attitudes (${\beta}=.645$, p<.001) and visit intentions (${\beta}=.157$, p<.001). The information attributes of TV restaurant programs and the causal relationship between empathy of consumers were examined. We also verified that empathy positively affects attitudes toward intentions to visit restaurants introduced on TV restaurant programs. Limitations and future research directions are also discussed.

  • With the advent of the knowledge economy, science and technology resources have played an important role in economic competition, and their optimal allocation has been regarded as very important across the world. Thus, allocation optimization research for regional science and technology resources is significant for accelerating the reform of regional science and technology systems. Regional science and technology resource allocation optimization is modeled as a double-layer optimization model: the entire system is characterized by top-layer optimization, whereas the subsystems are characterized by bottom-layer optimization. To efficaciously solve this optimization problem, we propose a mixed search method based on the orthogonal genetic algorithm and sensitivity analysis. This novel method adopts the integrated modeling concept with a combination of the knowledge model and heuristic search model, on the basis of the heuristic search model, and simultaneously highlights the effect of the knowledge model. To compare the performance of different methods, five methods and two channels were used to address an application example. Both the optimized results and simulation time of the proposed method outperformed those of the other methods. The application of the proposed method to solve the problem of entire system optimization is feasible, correct, and effective.

  • The primary purpose of this study was to quantitatively examine whether there was a difference in the settling velocities of cohesive sediments in the Saemankeum artificial lake before and after the closure of the Saemankeum seadike. Through in situ sediment sampling and laboratory experiments, the settling velocities were estimated as a function of the suspension concentration and their physico-chemical properties, such as grain size distribution, the percentage of organic contents, mineralogical composition, etc. were also examined. In this study, their inter-relation with settling velocities were also analyzed qualitatively. The result of the settling tests for Saemankeum sediments showed that there was a big difference in the settling velocities before and after the closure of the Saemankeum seadike. Its settling velocities in a flocculated settling region became remarkably larger after the closure compared to those before the closure, while they were similar but relatively smaller in a hindered settling region. This was found to be mainly due to the difference in their grain size.

  • Korea huts been dramatically changed during the last century in many aspect of society, with the introduction of western culture in the beginning of 20th century. This study aims at understanding the changes in our traditional culture shown by costume as well as examining the aspects of the changes of traditional clothing according to age, by comparing the differences of our traditional dress Hanbok between ear1y and the late of the 20th century. Analysis of photographs showing Hanbok of both ages was used. 155 photographs of people wearing traditional Hanbok in the beginning of the 20th century were collected from the photo collection books portraying various living conditions of common people at that time. 748 Photographs of Hanbok worm today were obtained by taking pictures of various occasions like wedding ceremonies in 5 big cities during 1997. The process of analysis consists of 3 stages: setting standards, sorting, and grouping by positioning. The results showed that traditional Hanbok room in the early 20th century has maintained its basic silhouette and design during the century, but the methods of color coordination, ornamentation, construction have underdone many changes in detail. Consequently, traditional frame exits, but actually there are many variations of tradition produced by individual tastes and fashion trend. These changes show that continuing influx of the western culture which has made enormous social changes in Korea had an influence even on Hanbok.

  • This study examined the background and change of building Yeongam eupseong and characteristics and construction method of its spatial structure. The results of this study can be summarized as follows. First, Yeongam eupseong was built for the same purpose of national border defense against the invasion of Japanese army as other Eupseongs were built and it was found first in the literature in the era of King Munjong of Joseon Dynasty with the scale of three gates and 4,369 cheok of castle wall. Such a scale was continued and in particular, according to flat structure, road network and gate position shown in the map, the form and road system of Yeongam eupseong before the 19th century were mostly identical with the current ones. Second, castle wall was built over foundation by using talcum after leveling the foundation soil and castle wall can be divided into outer wall, filling part and inner wall from the section. Outer wall was constructed by inserting and layering pebbles with big irregular stone, filling part was made with talcum and riprap and inner wall with soil in several layers by keeping gradient. This building method showed common features in inserting and layering pebbles for outer wall, use of protruded base and section form compared to Jeollado Eupseong.

  • Program source code is a set of complex syntactic information which are expressed in text forms, and contains complex logical structures. Structural and logical complexity inside source code become barriers in applying visualization techniques shown in traditional big-data approaches when the volume of source code become over ten-thousand lines of code. This paper suggests a procedure for making visualization of structural characteristics in source code. For this purpose, this paper defines internal data structures as well as inter-procedural relationships among functions. The paper also suggests a means of outlining the structural characteristics of source code by visualizing the source codes with network forms The result of the research work can be used as a means of controling and understanding the massive volume of source code.
