  • As a leading institution for conservation science in Korea, the National Museum of Korea (NMK) has conducted diverse efforts in this field through conservation treatment, analysis, research, and other relevant affairs over the past four decades. However, conservation science at the NMK has been facing difficulties due to insufficient human resources for handling its extensive collection, decrepit equipment, an expanding number of requests for support from other institutions, and increasing calls for enhancing its functions. In view of these challenges, this study diagnosed the current situation and examined the functions required in order to suggest plans for the development of conservation science at the NMK. In this regard, it reviewed current activities at the museum and conducted case studies of overseas institutions to propose five functions to be enhanced or introduced at the NMK. First, the NMK should refine the existing functions of conservation treatment and enhance its support for conservation science. In addition, it is recommended to introduce and develop advanced analysis and diagnosis involving valuations, conservation environment management to counter climate change, and content-based digital conservation/restoration. The functional enhancements and introduction of the new functions as described above would help the NMK develop into a leading center for conservation science in Asia.

  • A geographical information systems(GIS) was a useful aid in the assessment of urban nonpoint source pollution and the development of a pollution control strategy. The GIS was used for data integration and display, and to provide data for a nonpoint source model. An empirical nonpoint source loading model driven by land use was used to estimate pollutant loadings of priority pollutant. Pollutant loadings were estimated at fine spatial resolution and aggregated to storm sewer drainage basins(sewershedsl. Eleven sewersheds were generated from digital versions of sewer maps. The pollutant loadings of individual land use polygons, derived as the unit of analysis from street blocks, were aggregated to get total pollutant loading within each sewershed. Based on the model output, a critical sewershed was located. Pollutant loadings at major sewer junctions within the critical sewershed were estimated to develop a mi t igat ion strategy. Two approaches based on the installat ion of wet ponds were investigated -- a regional approach using one large wet pond at the major sewer outfall and a multi-site approach using a number of smaller sites for each major sewer junction. Cost analysis showed that the regional approach would be more cost effective, though it would provide less pollution control.

  • The purpose of this study was to analyze the elementary pre-service teachers' perspectives on the use of the elementary mathematics textbooks by observing mathematics classes at the schools and to present suggestions on the use of textbooks in the mathematics classes. For this study, let 54 pre-service elementary school teachers observe a total of 54 classes (1,299 students) in the first through sixth grades at 15 areas in Seoul city. With the observations of the mathematics classes, the researcher analyzed the pre-service elementary teachers' perspectives on the use of resources including mathematics textbooks in the elementary mathematics classes. As a result of the study, the pre-service teachers recognized that mathematics textbooks are the main material for mathematics classes, but they think that they need to reconstruct the contents of the textbooks for effective teaching and learning mathematics. In addition, various additional materials need to be used in order to help students learn mathematics more effectively, including by differentiated materials. Also, instruments used in the classes were mainly consisted of TV and PPT data. Pre-service teachers were not much satisfied with the contents of the elementary mathematics textbooks. However, they did not feel the need for development of digital textbooks. The researcher suggested a long term research on how to use study materials such as textbooks within the overall mechanism of teaching and learning processes. Also, practical teacher education programs that include applications of textbooks at schools are necessary in order to improve the quality of mathematics teaching and learning.

  • Convolution filtering methods have been widely applied to various digital signal processing fields for image blurring, sharpening, edge detection, and noise reduction, etc. According to their application purpose, the filter mask size or shape and the mask value are selected in advance, and the designed filter is applied to input image for the convolution processing. In this paper, we proposed an image processing acceleration method for the convolution processing by using two-dimensional Look-up table (LUT) and overlap-region buffering technique. First, based on the fixed convolution mask value, the multiplication operation between 8 or 10 bit pixel values of the input image and the filter mask values is performed a priori, and the results memorized in LUT are referred during the convolution process. Second, based on symmetric structural characteristics of the convolution filters, inherent duplicated operation region is analysed, and the saved operation results in one step before in the predefined memory buffer is recalled and reused in current operation step. Through this buffering, unnecessary repeated filter operation on the same regions is minimized in sequential manner. As the proposed algorithms minimize the computational amount needed for the convolution operation, they work well under the operation environments utilizing embedded systems with limited computational resources or the environments of utilizing general personnel computers. A series of experiments under various situations verifies the effectiveness and usefulness of the proposed methods.

  • The purpose of this study is to establish academic identity as well as produce human resources that industries need by grasping curriculum of the departments related beauty focusing on Korean colleges (junior colleges and four year course colleges), analyzing examples of advanced countries and suggesting their developmental direction. For the research method, the reference period of curriculum in Korean colleges was from Jul. 05th, 2011 to Aug. 05th, 2011. the investigation method is as follow: first, the curriculum of the departments related to beauty which were registered in the web sites were investigated. Second, the documents were received by fax and Email from each department after calling it. Third, questions and answers were done in reference to majors on the phones. these methods are intended for 65 junior colleges and 16 four year course colleges (total 81 ones). It clarified that lifelong education centers and the graduate courses were ruled out. the statistical analysis about data which were investigated like this were done by the frequency analysis. The results which examined the major subjects of Make-up focusing on Korea and foreign countries are as follow: First, the result which examined the major and theory subjects of Make-up has found that there are the human body theory, the equipment theory, the marketing theory are the management theory in Korean junior colleges and physiology/chemical, management, marketing and equipment product were treated in four year course colleges of Korea. As for foreign colleges, the subjects related to history and culture are mainly treated as the theory courses and their purpose is to cultivate basic knowledge of the fields which are mainly connected to Make-up including plays, movies, TV and studios. Second, the result which examined practice subjects of Make-up major has found that practice subjects of the total ones are of great importance in junior colleges. And it could be found that the Make-up field is of little importance as it is not independent and exists with the hair and skin fields in one department in the four year course colleges. Especially, in the foreign countries, the more detailed and professional subjects including classes which treat digital media, studio technologies, production, wigs and the special effects were treated by the field class system and these characteristics implies that Korean curriculum should be changed in the future. Based on this analytical results of investigation, this researcher tried to propose the developmental direction of Korean curriculum in the future.

  • The present study investigates the realization of tourism culture welfare by using Confucian heritage. From June 13 to November 7, 2014, site surveys and interviews were conducted for hyanggo (hyanggo: Confucian temple and school to teach students in Joseon Dynasty period), seowon (seowon: a memorial hall for Confucianist services to honor distinguished scholars and statesmen) and nujung (nujung: outdoor pavilion or gazebo) located in Youngwol -gun. Questionnaire pertaining to site survey and in-depth interviews for the building owners and managers was used to collect necessary data and scientific investigation was performed for analysis. As a result, the historical background was found to be culturally valuable asset for both region's tourism and culture welfare. Secondly, hyanggyo and seowon were found to exhibit traditional Confucius cultural form, while nujung exhibited a rare architectural trait. Hence it seems necessary to develop a different social tourism resource specialized for nujung. Thirdly, the rendering of Confucius heritages to tourism culture welfare resources thus far seems to be insufficient; hence, development and operation of marketing programs will be necessary. The implications of the present study require succession and modern reinterpretation of Confucian heritages for further development into digital tourism that will encompass Confucian culture and today's culture. Furthermore, studies of the tourism culture welfare policies that will promote the co-existence with the region will be needed.

  • The emergence of compact and low-power wireless communication sensors and actuators in the technology supporting the ongoing miniaturization of processing and storage allows for entirely the new kinds of embedded systems. These systems are distributed and deployed in environments where they may have been designed into a particular control method, and are often very dynamic. Collection of devices can communicate to achieve a higher level of coordinated behavior. Wireless sensor nodes deposited in various places provide light, temperature, and activity measurements. Wireless sensor nodes attached to circuits or appliances sense the current or control the usage. Together they form a dynamic and multi-hop routing network connecting each node to more powerful networks and processing resources. Wireless sensor networks are a specific-application and therefore they have to involve both software and hardware. They also use protocols that relate to both applications and the wireless network. Wireless sensor networks are consumer devices supporting multimedia applications such as personal digital assistants, network computers, and mobile communication devices. Wireless sensor networks are becoming an important part of industrial and military applications. The characteristics of modem embedded systems are the capable of communicating adapting the different operating environments. In this paper, We designed and implemented sensor network system which shows through host PC sensing temperature and humidity data transmitted for wireless sensor nodes composed wireless temperature and humidity sensor and designs sensor nodes using embedded system with the intention of studying USN.
