The purpose of this study is to identify with visual data whether interest in eSports affects the poster's information search. Scan path and hit map were collected using eye tracker and eye tracking program. As a result, 1) In the case of interest, the event was the first to notice, and in the case of non-interested was the first to see the title. 2) The amount of information collected by interested persons was greater. 3) In the case of interest, the most attention stayed on the event, and in the case of non-interested, the most attention stayed on the title. If additional research on eSports is conducted, various approaches can be used as marketing materials that can be applied to poster design production.

CdS thin films have been widely used a window material in heterojunction solar cells. In solar cell systems, where CdS thin films have been proved to be useful, partial substitution of Zn for Cd increases the optical window of the hetero-junction and also the diffusion potential. In this thesis, effects of the thickness of indium films and the annealing temperature on structural, optical and electrical properties of chemically deposited CdZnS films for the efficiency of the Cd_(1-x)Zn_(x)S/CdTe solar cells were investigated. Cd_(1-x)Zn_(x)S films were grown by chemical bath deposition (CBD), which is a very attractive method for low-cost and large-area solar cells. The open circuit voltage of Cd_(1-x)Zn_(x)S/CdTe solar cells increased due to reduced electron affinity difference between Cd_(1-x)Zn_(x)S and CdTe films. However, the conversion efficiency of Cd_(1-x)Zn_(x)S/CdTe solar cell decreased because of the higher series resistance(R_(s)) than CdS/CdTe solar cell. The series resistance and conversion efficiency of Cd_(1-x)Zn_(x)S/CdTe solar cell were improved by using indium-doped Cd_(1-x)Zn_(x)S films as window layer. Cd_(1-x)Zn_(x)S/CdTe solar cells fabricated with optimal conditions exhibited V_(oc)=630mV, J_(sc)=38.89mA/㎠ , FF=0.53, and η=13.2%

In this thesis, effects of the thickness of indium films and the annealing temperature on optical and electrical properties of chemically deposited CdZnS films for the efficiency of the Cd1-xZnxS/CdTesolar cells were investigated. To improve the electrical conductivity of Cd1-xZnxs films, thin indium films(10-4Onm thickness)were evaporated on the suface of Cd1-rZnxs films. Experimental parameters such as indium film thickness, Zn mole fraction, and the annealing temperature in terms of structural and electrical properties of Cd1-xZnxs films were investigated. The diffusion process was carried out by heating the sample in air at 150-550℃ for 20 minute As the indium film thickness is increased, the resistivity decreases and the lowest value(0.3 O -cm)is obtained for Cd1-xZnxs films annealed at 450℃ with 40nm of the thickness.

The purpose of this study is to determine the ageing mechanism of Mica/Epoxy composite material for large generator stator windings in order to estimate remaining life of generator. X-ray analysis is performed to investigate the position and structure of mica crystal in insulation materials. The phase change of aged and sound specimen under each atmosphere isn't observed. Surface analysis of insulation materials by optical microscope also show that the sound and aged specimen, sliding phenomenon by shear and thermal stress is observed both interface between mica and epoxy.

Recently, the structure are more higher and larger, so that the application of high-strength concrete is increased. And as the development of construction skills, it is possible to place during the winter. Concrete work during winter is indispensable to shorten time of completion and cut costs. When Concrete work during winter is placed, it has anxiety that concrete freeze at low temperature. As repetition of concrete's freezing cause reduction of durability, it is necessary for mixing to pay attention to Air contents and W/C ratios. Accordingly, in this study, we estimate the Frost Resistance by Air contents and W/C ratios, and development of strength after Early-Frost Damage in the High-Strength Concrete during the cold weather. In this study, it could be confirmed that factors which were Air contents, W/C ratios and early curing period, affected on the Frost Resistance.

Korea Aerospace Research Institute (KAKI) is developing a Korea Multi-Purpose Satellite I (KOMPSAT-1) which accommodates Electro-Optical Camera (EOC), Ocean Scanning Multi-spectral Imager (OSMI), and Space Physics Sensor (SPS). The satellite has the weight of about 500kg and will be operated on the 10:50 AM sun-synchronized orbit with the altitude of 685 km. The satellite will be launched in 1999 and its lifetime is expected to be over 3 years. The main mission of EOC is the cartography to provide the images from a remote earth view for the production of 1/25000-scale maps of KOREA. EOC collects 510 - 730 nm panchromatic imagery with the ground sample distance(GSD) of 6.6 m and the swath width of 17 km by push broom scanning. EOC also can scan ±45 degree across the ground track using body pointing method. The primary mission of OSMI is worldwide ocean color monitoring for the study of biological oceanography. It will generate 6 band ocean color images with 800 km swath width and 1km GSD by whiskbroom scanning. OSMI is designed to provide on-orbit spectral band selectability in the spectral range from 400 nm to 900 nm through ground command. This flexibility in band selection can be used for various applications and will provide research opportunities to support the next generation sensor design. SPS consists of High Energy Particle Detector (HEPD) and Ionosphere Measurement Sensor (IMS). HEPD has missions to characterize the low altitude high-energy particle environment and to study the effects of radiation environment on microelectronics. IMS measures densities and temperature of electrons in the ionosphere and monitors the ionospheric irregularities at the KOMPSAT orbit.

<P>The present study employed nerve guidance conduits (NGCs) only, which were made of small intestine submucosa (SIS) and poly(caprolactone-co-lactide) (PCLA) to promote nerve regeneration in a peripheral nerve injury (PNI) model with nerve defects of 15?mm. The SIS- and PCLA-NGCs were easily prepared by rolling of a SIS sheet and a bioplotter using PCLA, respectively. The prepared SIS- and PCLA-NGCs fulfilled the general requirement for use as artificial peripheral NGCs such as easy fabrication, reproducibility for mass production, suturability, sterilizability, wettability, and proper mechanical properties to resist collapsing when applied to in vivo implantation. The SIS- and PCLA-NGCs appeared to be well integrated into the host sciatic nerve without causing dislocations and serious inflammation. All NGCs stably maintained their NGC shape for 8 weeks without collapsing, which matched well with the nerve regeneration rate. Staining of the NGCs in the longitudinal direction showed that the regenerated nerves grew successfully from the SIS- and PCLA-NGCs through the sciatic nerve-injured gap and connected from the proximal to distal direction along the NGC axis. SIS-NGCs exhibited a higher nerve regeneration rate than PCLA-NGCs. Collectively, our results indicate that SIS- and PCLA-NGCs induced nerve regeneration in a PNI model, a finding that has significant implications in the future with regard to the feasibility of clinical nerve regeneration with SIS- and PCLA-NGCs prepared through an easy fabrication method using promising biomaterials.</P>
