  • The tactical datalink system has been recognized as the key element in Network Centric Warfaret(NCW). The military has been putting great efforts into establishing datalink system using existing tactical radio and UMPC. but the aircraft operational environment and the requirement specification for equipments mounted in the avionics are differentiated with those in other platforms, so special efforts are needed to select suitable UMPC. In this paper, we consider the requirement analysis for UMPC in respect of processor performance, operation system (OS) and NVG compatibility. Additionally we have to make a effort to understand the operational environment of aircraft and examine th standard to select the appropriate UMPC, and then we expect to establish the tactical datalink system successfully.

  • This article proposed polarization selective antenna for UHF RFID system. The proposed antenna is consist of microstrip patch antenna with dual feeding and two SPDT switches and a SP4T switch and 3dB hybrid coupler. Through control of voltage of switches, the proposed reader antenna can select horizontally linear polarization, vertically linear polarization, left-hand circular polarization (LHCP) and right hand circular polarization (RHCP). The proposed reader antenna satisfied 2:1 VSWR at 902MHz ~ 928MHz. and 3dB under AR(axial ratio). And it can select appropriative polarization with user environment and tag polarization. So it minimize PLF and increased reading distance.

  • MANET(Mobile Ad hoc NETwork) routing protocols have merits and demerits under the specific situations. Because it is not clear which protocol is the best under all situations, a suitable routing protocol should be selected depending on the traffic and moving characteristics of nodes. The aim of this paper is to select an appropriate routing protocol to be used by the Korea Coal Corporation. So we designed working scenarios such as coal mining and tunnel supporting that reflected mobile characteristics of nodes. We constructed coal mining and tunnel supporting topology, and analyzed the performance of MANET routing protocols. This result can be used as a basis to select a MANET routing protocol in underground tunnel environment and other mine of the Korea Coal Corporation.

  • In this thesis, Wi-Fi Direct which can communicate with other device without AP, we study how to be selected GO considering multi-user connection and we apply it to application. We give the weight how many time a device was GO and how many time the device connected with other devices in 24 hours. With this value, the device is selected to GO when other devices request the connection. We show that the application which we implemented select right GO.

  • In order to improve the effectiveness of software process improvement, more than two models can be use to compensate the weakness of each other. One of integrated models is the one in which CMMI and software six sigma. However, it is very difficult for a small software development organization to select and apply an appropriate set of six sigma tools since there are a lot of six sigma tools and statistical knowledge is required. In this paper, we suggest a six sigma tool selection process to help small organizations select six sigma tools effectively based on organization business value. Thereby, small organizations can efficiently implement CMMI by adopting an appropriate set of six sigma toolkits.

  • In this study, we try to select the sites and set the boundary in the Improvement Promotion Project as a case analysis of Busan Metropolitan City Area. Specifically speaking, we build the database of the city improvement promotion project area, spread out collectively in the Busan City, select the possible sites recommended by the basic units of local government, and analyse these sites through applying our physical standards. The result is as follows ; The degree of advancement and driving willpower from the basic units of local government are largely effective on the improvement project, but in terms of accessibility, decrepitude, and development density, there are relatively negligible differences among the possible sites.

  • We have screened phage display peptide libraries to select for peptides binding to various sized $TiO_2$ nanoparticles. Phage libraries displaying random 7mer, 12mer, and C-7-Cmer peptides were used for screening. The size of target $TiO_2$ particles used were 7 nm, 15 nm, and 25 nm in diameter. We could select peptides binding each nanoparticles from all 3 libraries. Their binding was confirmed by transmission electron microscopy (TEM). Each peptide investigated was also shown to bind the other sized particles, meaning that the binding was specific for the nature of the particle rather than for the size of it. One of the 7mer peptides (PEP9, SVSPISH) was chosen for further analysis. The binding was shown to be in a dose-dependent manner, suggesting a specific interaction.

  • This article provides an overview of the current concepts regarding anterior cruciate ligament reconstruction, including anatomy, biomechanics, operative techniques and clinical results. Many techniques have been introduced for ACL reconstruction: single bundle reconstruction, remnant preserving augmentation, and double bundle reconstruction. Each technique has its strong and weak points, and it is not sure which technique is superior than others. It is considered to suggest that rather than to select the same method of surgery in all patients, select the method of reconstruction depending on the characteristics of the individual patient, the state of the residual ligaments and extent of the damage.

  • This study was conducted to establish an effective palate cleanser when conducting descriptive analysis for gochujang products. In addition, descriptive analysis procedure for gochujang products was optimized. A generic descriptive analysis was performed on 4 types of gochujang samples varying in hot and spicy levels. The sensory attributes developed were 9 odors, 13 flavors, 4 texture and mouth feel attributes, and 4 appearance attributes. In order to select an effective palate cleanser for gochujang, 5 types of cleansers were tested (water, water+bread, water+cucumber, water+milk, water+cracker). Correct answering rate, significant numbers of product effect on sensory attributes, and the mean hot and spicy intensity values were considered to select the optimal palate cleanser. Results showed that as the hot & spicy level increased, red pepper odor and flavor significantly increased whereas umami taste intensity decreased. When comparing the efficiencies of various palate cleanser, the correct answer rates were the highest when warm water was used with either cucumber or cracker. Additionally, the attribute intensities were better differentiated between gochujang samples when cracker, white wheat bread, or cucumber were used. Overall, warm water with cucumber or cracker were shown to be the most effective cleansers.
