  • It is necessary to prepare a stable production base in advance for a change in the global grain market, and it is required to prepare comprehensive countermeasures such as securing technical skills and cultivation technology. Therefore, Korea, which relies on imports of major grains other than rice, could be exposed to a food crisis at any time unless the self-sufficiency rate of grains is improved. In order to respond to this new food crisis, it is necessary to find ways to efficiently utilize rice fields to increase the domestic grain self-sufficiency rate. From this point of view, interest and demand for the generalization of farmland that can be used as paddy fields and returned to paddy fields are increasing, and related research is also being continuously performed. In order to select a multipurpose farmland project site, this study extracted farmland containing 10% or more purchased and stockpiled farmland through spatial analysis (buffer, dissolve, intersect, etc.), and finally presented areas subject to multipurpose farmland projects. The target site for the multipurpose farmland project was finally selected by integrating data onto a point-by-point basis so that the current status of farmland purchased and stockpiled, Farm Manager Registration Records, and the Korean Soil Information System data (drainage classes, surface soil texture, field-suitability classification, etc.) can be used in combination. There are 175 areas where the multipurpose farmland is possible. Incheon 2, Gyeongbuk 40, Gangwon 2, Chungbuk 7, Chungnam 48, Jeonbuk 34, Jeonnam 19, Gyeongbuk 15, Gyeongnam 8. Chungcheongnam-do has the most target site for the multipurpose farmland project, and Gangwon-do is the least. It is expected to contribute to new commercialization and business expansion by deriving business areas by identifying the scale of the farmland multipurpose farmland project using Farm Manger Registration Records and spatial data.

  • Many cities are utilizing their cultural capital as a means for urban regeneration and tourist attraction. Museums form an essential component in these culture-based urban regeneration efforts, the Guggenheim Bilbao being a frequently cited example of success. The United Arab Emirates (UAE) has benchmarked the Bilbao case study as they were looking for alternative income-generating industries in the post-oil era, embarking on a city-building project on the Saadiyat Island where resorts and cultural institutions of massive scale are being constructed. The Louvre Abu Dhabi and the Guggenheim Abu Dhabi were pursued under this scheme, aiming at attracting tourism and elevating their status in the region as a cultural capital. This study examines the political, economic, and cultural background behind the Saadiyat city project and the pending issues behind the construction of the Guggenheim Abu Dhabi. This study purports that besides funding and an ambitious plan, social and cultural developments in the region over time will be essential for a successful localization of a Western brand museum in the region.

  • Objective: To investigate the cortical disinhibition in diabetic patients with neuropathic pain and without pain. In addition, we assessed the cortical disinhibition and pain relief after repetitive transcranial magnetic stimulation (rTMS). Method: We recruited diabetic patients with neuropathic pain (n = 15) and without pain (n = 15). We compared the TMS parameters such as motor evoked potential (MEP) amplitude, cortical silent period (CSP), intracortical inhibition (ICI %) and intracortical facilitation (ICF %) between two groups. Moreover, we evaluated the changes of pain and TMS parameters after five consecutive high frequency (10 Hz) rTMS sessions in diabetic patients with neuropathic pain. The neuropathic pain intensity (visual analog scale) and TMS parameters were assessed on pre-rTMS, post-rTMS 1day, and post-rTMS 5 day. Results: The comparison of the CSP, ICI % revealed significant differences between two groups (p<0.01). After rTMS sessions, the decrease in pain intensity across the three time points revealed a pattern of significant differences (p<0.01). The change of CSP and ICI % across the three test points revealed a pattern of significant differences (p<0.01). The ICI % revealed immediate increase after first rTMS application and significant increase after five rTMS application (p<0.01) in diabetic patients with neuropathic pain. The MEP amplitude and ICF % did not reveal any significant changes. Conclusion: Our findings demonstrate that cortical inhibition was decreased in diabetic patients with neuropathic pain compared with patients without pain. Furthermore, we also identified that five daily rTMS sessions restored the defective intracortical inhibition which related to improvement of neuropathic pain in diabetic patients.

  • A residential space where a person lives in may change following the flow of time and it has evolved in various shapes through the development process of a city. In particular, after the 1900s when the modern urban planning was first applied in full-scale, the urban environment and residential environment have formed cities through systematic planning. Under the assumption that the level of satisfactory life for urban residents residing in such an urban environment would be influenced mutually with the residential environment and urban environment to carry out this study, and as for the methodology of this study, the questionnaire was implemented with the subject of residents in Seoul City and analysis was implemented for regression analysis through SPSS 20.0 program. The results of the study are shown as follows. First, the relationship of the residential environment and urban environment is classified for convenience, safety and pleasance to have the important implication, and the level of satisfaction for the residential environment is analyzed to show implications with influence on the level of satisfaction for settlement consciousness. Second, the relationship of influence of residential environment on the settlement consciousness with the characteristics of urban environment is statistically noticeable and the stability and pleasance would have the statistically noticeable influence on satisfactory residential environment and the convenience would not render noticeable influence. And, third, under the characteristics of urban environment, convenience does not have direct influence on the settlement consciousness and it is confirmed to influence on the settlement consciousness indirectly only through the satisfaction of variation in the residential environment.

  • Weather radar images can be used in a variety of ways because of their high visibility in terms of visuals. In other words it has the advantage of being able to grasp the flow of weather phenomena using not only the raw data of the weather radar, but also the change characteristics between consecutive images. In particular image processing techniques are gradually expanding in the field of meteorological research, and in the case of image data having high resolution such as weather radar images it is expected to produce useful information through a new approach called image processing techniques. In this study the weather phenomena flow was calculated as a vector from the change of the weather radar image according to time interval with the optical flow method, one of the image processing techniques. The characteristics of the weather phenomena to be analyzed were derived through vector analysis resolution suitable for the scale of weather, vector interpolation in regions where no radar echo exists, and the removal of relative flow vectors to distinguish the flow of specific weather and the entire atmosphere. Through this study, it is expected that not only the use of raw data of weather radar, but also the widening of the application area of weather radar, such as the use of unique characteristics of image data, and the active use of image processing techniques in the field of meteorology in the future.

  • The response surface method (RSM) is widely adopted for the structural reliability analysis because of its numerical efficiency. However, the RSM is still time consuming for large-scale applications and sometimes shows large errors in the calculation of sensitivity of reliability index with respect to random variables. Therefore, this study proposes a new RSM in which moving least squares (MLS) approximation is applied. Least squares approximation generally used in the common RSM gives equal weight to the coefficients of the response surface function (RSF). On the other hand, The MLS approximation gives higher weight to the experimental points closer to the design point, which yields the RSF more similar to the limit state at the design point. In the procedure of the proposed method, a linear RSF is constructed initially and then a quadratic RSF is formed using the axial experimental points selected from the reduced region where the design point is likely to exist. The RSF is updated successively by adding one more experimental point to the previously sampled experimental points. In order to demonstrate the effectiveness of the proposed method, mathematical problems and ten-bar truss are considered as numerical examples. As a result, the proposed method shows better accuracy and computational efficiency than the common RSM.

  • Both Earth science II and Korean geography textbooks emphasize the importance of content related to 'geology of the Korean Peninsula'. This study aimed to analyze the differences in the content related to the 'geology of the Korean Peninsula' presented in the textbooks, and to find out whether these differences are consistent with the latest scientific knowledge in any inconsistencies are found. For this purpose, seven textbooks (four Earth science II and three Korean geography) published under the 2015 revised curriculum were selected as the subject of analysis, and the difference in the description of the tectonic provinces of the Korean Peninsula, geologic time scale, and explanatory texts of geological characteristics between Earth science II and Korean geography textbooks were compared. As a result of the analysis, there are some cases of inconsistencies between Earth science II and Korean geography textbooks in terms of terminologies, names, and distribution ranges related to the tectonic provinces of the Korean Peninsula. The Korean geography textbooks had inconsistencies in the geochronologic data of the rocks as they cited outdated data. In addition, inconsistencies were found in the explanatory texts describing the 'distribution of rocks on the Korean Peninsula', 'characteristics of the Pyeongan Supergroup', and 'great hiatus of the Paleozoic Era'. Both Earth science and Geography have many concepts in common, therefore, effort is needed to minimize the differences in content. It is important to select the content appropriately which should reflect the latest scientific knowledge and presents the concepts consistently.

  • After being introduced into franchises industry, franchise has made a phenomenal growth in a short time and a substantial contribution to job creation and economic revitalization. Nevertheless, franchise business operators failed a business or low profit because of a lack of information and indiscriminate foundation. Therefore the first object of this study is characteristics of franchise's factors on disclosure agreement in franchise associate website. second is examinations about casual relationship between factor and franchise performance with using Excel and SPSS 18.0 versions. The findings of present study were as follows. First, franchises manage small business mostly(financial data, scale so on) and franchise's type focused the food service industry. Specially, a business district select unprotected contract. Second, in franchise's factors, we could find statistically significant effect on annual average sales and annual average net profit. However growth rate of franchise don't have statistically significant effect. Third, we could find statistically significant difference on analysis both franchises' factors and financial data. In conclusion, we must consider of franchise industry environment and success effect on performance in starting one's business. Furthermore franchises plan ways for their sustained growth and protection of rights and interests. Finally business operator draw up their information and upgrade continuously for franchises industry growth.

  • The purpose of the study was to investigate the perception and the knowledge of the Korean traditional foods in elementary school students. For the investigation, 373 fifth-grade elementary school students in Incheon were surveyed by a questionnaire, and the data were analized by the SPSS 10.0 program. The result showed that 85% of the surveyed schoolchildren showed the interest in the Korean traditional foods. It also revealed that female students are more interested in the traditional food than male students and the children of the career woman are more interested than those of the housewives. As for the motive of their interest, 39.7% of the subjects answered 'through mass media'. Male students and the children of the housewives got the interest through their mother, and female students and the children of the career woman got the interest through their hobby of cooking food. Among the traditional foods, 76.4% of the children designated kimchi as the most proud traditional food. As for the reasons of reducing traditional food use, 39.9% of students responded because of 'not-tasty' and 28.7% of students replied because of 'not enough time to cook'. But 62.2% of the subjects thought the traditional foods should be more used in the future. As for the succession and development of the traditional foods, 33.8% of the subjects said it should be carried out by the family. The basic knowledge score of the traditional foods was 5.78 on a scale of 10, which showed relatively low level. The lower their basic knowledge, the less their interest in the traditional foods was. The samgyetang, ogokbap and bindaetteok were the most perceived traditional foods. The cheonggukjang, nabakgimchi and jindallaehwajeon were the foods they had seen, but the they didnot have heard or seen the others. Among the traditional foods, susugyeongdan, jindallaehwajeon and dasik were more perceived by the schoolchildren in the rural area than those in the urban area. The jindallaehwajeon and dasik were more perceived by female students than by male students. Therefore, in order to make elementary schoolchildren take the traditional foods with pride by increasing their perception and knowledge of them, the family should give them many opportunities to eat traditional foods. The school also should try to establish a cooperative relationship to the family of schoolchilderen and use more Korean traditional foods in the school's meal program. Furthermore, the society's concern and support are necessary and also the role of mass media, which have great influence on children, is important.

  • In conventional structural design, deterministic optimization which satisfies codified constraints is performed to ensure safety and maximize economical efficiency. However, uncertainties are inevitable due to the stochastic nature of structural materials and applied loads. Thus, deterministic optimization without considering these uncertainties could lead to unreliable design. Recently, there has been much research in reliability-based design optimization (RBDO) taking into consideration both the reliability and optimization. RBDO involves the evaluation of probabilistic constraint that can be estimated using the RIA (Reliability Index Approach) and the PMA(Performance Measure Approach). It is generally known that PMA is more stable and efficient than RIA. Despite the significant advancement in PMA, RBDO still requires large computation time for large-scale applications. In this paper, A new reliability-based design optimization (RBDO) method is presented to achieve the more stable and efficient algorithm. The idea of the new method is to integrate a response surface method (RSM) with PMA. For the approximation of a limit state equation, the moving least squares (MLS) method is used. Through a mathematical example and ten-bar truss problem, the proposed method shows better convergence and efficiency than other approaches.
