  • This paper investigated far-infrared emission characteristics of ZrC imbedded heat storage knitted fabrics for emotional garment. For this purpose, ZrC imbedded heat storage PET was spun with high viscosity PET imbedded ZrC powder on the core part and low viscosity PET on the sheath part by conjugated spinning method. Ingredient analysis and far-infrared emission characteristics assessment of spun filament were carried out by EDS and FT-IR spectrometer. Two kinds of knitted fabrics were made using texturized ZrC imbedded PET for measuring thermal characteristics of ZrC imbedded heat storage PET. Zr peak was certified by EDS measurement and it was confirmed that content of Zr was 19.29%. Far-infrared analysis revealed that emission power at the range of wavelength, $5{\sim}20{\mu}m$ was $3.65{\times}10^2W/m^2$, and emissivity was 0.906. Heat storage analysis by KES-F7 system revealed that $Q_{max}$ of ZrC imbedded PET knitted fabric was lower than that of regular PET one and warmth keepability rate was higher than that of regular one, which means that ZrC imbedded PET knitted fabric has heat storage property. Thermal conductivity of ZrC imbedded PET knitted fabric was higher than that of regular PET one which was caused by high thermal conductivity of Zr itself. Hand property of ZrC imbedded knitted fabric was not inferior compared to regular PET knitted fabric, which preferably was found to be dependent on knit structure and surface property.

  • This study evaluates the drug delivery and biocompatibility of latanoprost imbedded disk in rabbit eye by assessing pharmacokinetics (PK), clinical signs, and histopathologic findings. During 84 days of experimental period, 48 New Zealand Rabbit (NZW) eyes were divided into control group which received no treatment and test material group which latanoprost were implanted intrasclerally. Pharmacokinetic assessment was performed to evaluate the drug delivery for 3 months. For biocompatibility, clinical signs were observed and histopathological analysis was done at 3 months post-operatively. The concentration of latanoprost in the iris tissue was maintained during the experimental period and the highest level of latanoprost was found at 4 weeks. However, the latanoprost was not found in the aqueous humor. Macroscopically, there was no evidence of clinical signs except for temporary hyperemia, neovascularization and edema immediately after surgery. On histopathological examination, there were no abnormal findings such as hyperemia, neovascularization, and edema in the eye tissues. The latanoprost imbedded disks has effectively released the drug into the adjacent tissue with high compatibility. Therefore, this study suggests that the drug delivery system with intrascleral latanoprost imbedded implants might be a novel approach as a treatment option for glaucoma.

  • In order to enhance the productivity of design and manufacture of injection molds, various computer-aided systems have been developed and introduced to mold manufacturers. The customized 3-D CAD systems for mold design is one of the most representative computer-aided system. However, these systems usually do not provide a convenient way to access and manage design knowledge implemented in them. To overcome this shortage, knowedge-based engineering systems have been developed, and now they are imbedded as modules of commercial CAD systems. In this paper, we introduced a 3-D design system for standard mold base based on Knowledge Fusion, a commercialized KBE system imbedded in Unigraphics. By introducing KBE system, design knowledge can be exposed to the users and modified by the end-users.

  • 3-Screen service means that one video contents is operated on 3 different terminals(smart-phone, IP-TV, internet PC) with same service browser. In this paper, we developed 3-Screen video service system based on imbedded web browser. We evaluated and analysed of developed 3-Screen service system through Agribusiness video service offering test environment on the LG U+ network. As a result of tests, it showed that 3-Screen video service was well performed in each 3-Screen service terminals. The result of this paper will be utilized in various application developments for the 3-Screen video service in the future.

  • Cooling tower is an important equipment of the cooling systems for large buildings like factory and department store. Water used for cooling in cooling tower is reused continuously. If the water is polluted, corrosion and scale can happen at equipments and pipes. In order to prevent this problem, it is necessary to control the water quality using chemicals. To control the water quality, an automatic control system is designed, fabricated, and experimented. The control system is based on an imbedded microcontroller. Relays are used for power driving, an LCD and LED for display, and RS485 for remote data acquisition. Monitoring program is also developed for easy man-machine interface and extraction of data stored in the imbedded processor and EEPROM. The control system calculates amounts of chemicals necessary using sensor data and injects the chemicals into the cooling tower on proper time. The developed water quality control system is expected to reduce cost of maintenance and extend the lifetime of the cooling systems with low cost.

  • Generally block imbedded type oil pump is adopted to make a small engine. In this paper 1D/3D numerical simulations were conducted to reduce energy consumption of the block imbedded type oil pump. At each stage of engine development we have estimated the oil flow rate and pressure to optimize oil pump sizes by using the 1D system analysis and then accomplished 3D CFD(Computational Fluid Dynamics) simulations to optimize oil pump shapes including inlet/outlet port. As a result, the energy consumption of oil pump has been reduced to nearly 27% and the engine fuel consumption to $1{\sim}1.5%$.
