| 1 | Predicting the Rainfall-Triggered Landslides in a Forested Mountain Region Using TRIGRS Model显示文摘Landslides are natural disasters which can pose a serious threat to human and property in many areas around the world. The Transient Rainfall Infiltration and Grid-based Regional Slope-stability (TRIGRS) model was used to investigate the rainfall-induced shallow landslides in a forested mountain region, Korea. Various input data for TRIGRS model include time-varying rainfall, topographic characteristics, soil depth, material strength, and hydraulic properties. A series of calculations were conducted in determining the slope stability over the Jangheung region in Korea during the storm occurred on August 6, 1998. The results show that TRIGRS model captured about 64.1% of landslides that were extracted from the IKONOS2 imageries. The model demonstrated how the factor of safety changed with time during a storm considering both the transient and spatial responses of pore water pressure in its slope stability calculation. | Dongyeob KIM Sangjun IM Sang Ho LEE Youngjoo HONG Kyung-Sub CHA | 2010 | Journal of Mountain Science2010，7，1： | 10 |
| 2 | Reliable cloud storage system for mobile devices using personal computer显示文摘In recent years,the use of mobile devices such as smart phones,tablet PCs,etc.is rapidly increasing.In case of these mobile devices,the storage space is limited due to their characteristics.To make up for the limited space of storage in mobile devices,several methods are being researched.Of these,cloud storage service(CSS),one of cloud computing services,is an efficient solution to compensate such limited storage space.CSS is a service of storing files to the storage and thus getting access to stored files through networks(Internet)at anytime,anywhere.As for the existing CSS,users store their personally important files in the cloud storage,not in their own computers.It may cause security problems such as the leaking of information from private files or the damaging to the information.Thus,we propose a cloud storage system which can solve the security problem of CSS for mobile devices using the personal computer.Our system is deigned to store and manage files through the direct communication between mobile devices and personal computer storages by using the software as a service(SaaS),one of computing services,instead of directly storing files into cloud storages. | Sanggeun Song Junghoon Shin Sangjun Lee | 2012 | Journal of Measurement Science and Instrumentation2012，3，3： | 1 |
| 3 | Efficient and Flexible 3D Virtual Desktop System in the Windows Environment显示文摘As personal computers have been recently improved in performance,a multi-tasking of running several applications at the same time has been generalized. Since only one task space is provided for performing such tasks in the Windows operating system,a number of computer users feel inconvenience.In this paper,we suggest a 3D Virtual Desktop System which can show a process of switching task spaces in 3D motion using DirectX. Our system aims to make up for the weak points in the Windows operating system,and to provide a computer user with more spaces for performing several tasks as well as the intuitive UI(User Interface),such as Compiz of Linux. | Seungpyo Hong Donsu Lee Sangjun Lee | 2010 | Journal of Measurement Science and Instrumentation2010，1，S1： | 1 |

| 11 | Design and implementation of digital content metadata system显示文摘Today's multimedia services are far beyond just the voice and data services:they have been diversified tremendously after fueled by the advancement of network infrastructures as well as the sudden surge of multimedia data itself.Currently,researches on metadata insertion,management and transfer keep going very well in order to provide a variety of services to users.In this paper,we propose the design and implementation methods of digital contents metadata system for insertion,storage and retrieval of metadata.The performance evaluation shows that the proposed method performs better than the existing method. | Jinho Seo Taewon Seo Junghoon Shin Sanggeun Song Cheng Dong Sangjun Lee | 2013 | Journal of Measurement Science and Instrumentation2013，4，4： | 0 |
| 12 | Design and implementation of user information sharing system using location-based services for social network services显示文摘Internet takes a role as a place for communication between people beyond a space simply for the acquisition of information.Recently,social network service(SNS)reflecting human’s basic desire for talking and communicating with others is focused on around the world.And location-based service(LBS)is a service that provides various life conveniences like improving productivity through location information,such as GPS and WiFi.This paper suggests an application combining LBS and SNS based on Android OS.By using smart phone which is personal mobile information equipment,it combines location information with user information and SNS so that the service can be developed.It also maximizes sharing and use of information via twit based on locations of friends.This proposed system is aims for users to show online identity more actively and more conveniently. | Donsu Lee Junghoon Shin Sangjun Lee | 2012 | Journal of Measurement Science and Instrumentation2012，3，2： | 0 |
