In order to manage the waterfront efficiently, we are to find the efficiency of producing method for digital orthophoto that presents natural form on lands and digital orthophoto cadastral map that presents the range of physical situation and property on lands in this study. Through this study, We can check that digital orthophoto cadastral maps for the boundary management of the waterfront are utilized widely at various field except the main purpose. Thus, we resolve the leading subjects that include the accuracy evaluation on produced maps and the bond edge of map sheet for the cadastral maps in order to drive activistic utilization and application.

It is the most important technological progress for the computer graphics when computer has incorporated the color system. However, color system used in computer is totally different from traditional color system like printing ink or painting color because it is exist only in the form of wavelengths of light on the computer screen. Therefore, some compatible problems are still remains with traditional design process or color matching in photography. It is important to produce precise representation and management of color in the current design system which is controlled and managed by computer to merge design process. In this study, I have discussed the merits of color, technological characteristics, designer's approach to color and traditional color system. Also I analyzed the aesthetic characteristics of computer color system which are found in computer graphics technology and compared them to traditional color system to try to find some opportunity and possibility for new method of development.

iATA(Internet Advanced Technology Attachment)는 TCP/IP 네트워크를 통해 원격의 대용량의 가상 저장 공간을 자신의 로컬 디스크 처럼 활용이 가능하게 하는 기술로 이는 모바일 기기(PDA, 휴대폰 등)와 같은 저장 공간의 부족문제를 가지고 있는 장치에 적용하여 저장 공간의 부족 문제를 근본적으로 해결할 수 있는 솔루션이라 할 수 있다. iATA는 SCSI 하드디스크가 장착된 시스템에서만 서버를 구축해야만 하는 iSCSI와는 달리 일반 가정이나 사무실에서 주로 사용하는 ATA 하드 디스크에도 서버 구축이 가능한 확장성을 가지고 있으며 이는 iATA의 최대 장점 중 하나라 할 수 있다. 또한, Web 사이트를 통해 많은 사람들이 iATA 서비스를 이용하여 자신의 모바일 기기에서의 저장공간 문제를 극복할 수 있으며, 최근 사회 문제로 크게 대두되고 있는 개인 정보 유출의 폐해를 막기 위해 개인 인증시 OpenSSL과 MD5를 이용한 보안/암호화 기법을 사용하여 개인 정보 유출에 의한 불이익 및 개인 정보 악용으로 인한 범죄를 막을 수 있다. 하지만, 기존의 iATA상에서는 디스크 관리가 서버에서만 가능하다는 문제점이 있다. 즉, 사용자만의 개인공간을 가질 수가 없다. 이처럼 개인 사진이나, 다이어리같은 정보들을 관리 할 수 없는 문제점을 해결하기 위해 클라이언트에서 자신만의 디스크 공간을 가질 수 있게 파티션을 할당해주고, 그 공간을 클라이언트만의 공간으로 만들어 주는 기술을 개발하는데 그 목적이 있다.

Diabetes is a major social problem in which the incidence and prevalence of diabetes increase every year around the world. Diabetes, characterized by high blood sugar, which increases the concentration of glucose in the blood, causes various symptoms and signs. As a result, patients should strengthen self-management in their daily lives. However, the biggest factor that patients fail in managing blood sugar is diet failure. Therefore, in this paper, an application was designed and implemented to input a diet through photography or image upload and analyze users' diets through intake indicators and blood sugar statistics.

This study analyzed the management plan of Seomjin River Chimsil Wetland by identifying landscape changes through aerial photographs analysis and concentrations of sedimentation. Geophysical Landscape Change Analysis showed that vegetation accounts for more than half of the total area. The Barren land and water body was somewhere repeatedly increased and decreased and made an irregular form in the study area. The soil was acidic, and no eurtophication was shown, but it was potential to form wetland. In addition, the research area has been terrestrification of sand bar for a long period of time, forming a soil layer. Although the characteristics of river deposits were shown in the study area, the grain size was a particulate matter, and the sorting was 'very poorly sorted'. In some areas of Seomjin River Chimsil Wetland, sand bars were formed, but most areas were undergoing to terrestrification. Therefore, in order to preserve the riverine area and to serve by a bridge between the land ecosystem and the underwater ecosystem, it is very necessary to remove some vegetation, create a proper waterway, and restore the wetland.

The purpose of this study is to produce and distribute a smart device based educational application for culinary practice. This study was performed from Jul. 1 to Dec. 30, 2012. The design of the application is composed of the theoretical contents, making methods, practice video and evaluation questions of Western cuisine among the contents of the culinary practice education. In addition, the notice and Q&A were added for the interaction between teachers and learners. For this study, 31 main dishes' pictures, 155 pictures for making processes by menu, 31 recipes, 31 cooking tips, 372 evaluation questions and 31 cooking videos about 31 menus were produced. The contents produced as above were directly inserted at 'http://kongju-fn.dslink.co.kr/super/index.html' to produce the application. This application can be found through searching with the word of 'yoribaksa'. This study can be considered to be significant in that this application was produced in the situation of the absence of any other previous applications for culinary practice education.

To analyze tendency of temporal and spatial change of shorelines and to estimate rate of shoreline changes using long-term shoreline change data is very important for the coastal environmental management. In this study, investigation was conducted to estimate the rate of shoreline changes using long-term shoreline change data from the year 1985 to 2009 aerial photographs. In this process aerial triangulation, GPS surveying and digital mapping was done for the estimation of changes. As the results, shorelines of Bangpo and Kkotji Beach retreated at a maximum rate of 0.2 m/yr and 0.8 m/yr, respectively. The shoreline could be changed by various factors. However, it was presumed that coastal erosion has been mainly affected by retaining wall constructed in the late 1990s.

The coastal area, which is managed by local governments, geographically, culturally and economically has been transformed into more influential space. In recent years, new type of fusion researches about coastal areas that have economic, cultural and engineering aspects, have been conducted. In this study, the multiple observations information was used to analyze change of Ilsan beach shoreline which is located in Dong-gu, Ulsan, Korea. For the shoreline analysis, we used VRS-RTK(Virtual Reference System by Real-Time Kinematic) GPS survey, aerial photograph, terrestrial LiDAR survey and fixed reference station survey. Specially fixed reference station method was suggested for shoreline observation and maintenance. In the case of Ilsan beach shoreline, according to the result of multiple observations information, coastline erosion(6~12m) appeared in medium and lower part and sedimentation(3~14m) in the upper part of coastline.

The vegetation such as grass, shrub, tree has been used to control the erosion and stabilize the slope for a long time. But the effects of vegetation on slope area is usually neglected in traditional stability analyses. There are many errors in slope analyses in thin soil mantles. Therefore the effects of vegetation is an important factor. But it is difficult and complex to represent the vegetation influence quantitatively in stability analysis. In this study, authors choose the landslide region at the Kum sung dong Kum-jung ku Pusan as a model area. Authors analyzed the degree of slope with the aerial photo interpretation and DTM data extracted from the topographic map, and the relationship of D.B.H. (diameter of breast height), height, and age of tree in field investigation data. Finally authors know the fact that landslide take place approximately 10 or 20 years later in arbitrary afforestable area where the degree of slope is 27. The prevention effect must be considered in the control of vegetation.

The purpose of this paper is to investigate the effect of the smart phone camera on the company's employees or employees of partner companies, we want to block things in advance. In this paper, we propose a smart phone camera control system which is connected with the personnel access right which enables to share the photographed image of the authorized user and the data shot only within the enterprise. To this end, we have developed the installation status of smart phone control program (MCS: Mobile Camera Control System) of employees, employees and visitors of company, and experimented and analyzed whether the smart phone control program installed in the authorized area. In addition, when visitors visited the company, the effect of prevention of photograph shooting through smart phone camera and the cost of seal sticker attached to the smart phone camera lens part were reduced.
