서비스 산업이 발달할수록 개인의 취향에 좋아하는 정보만을 제공받기 원하고 서비스를 받기 위한 대기시간이 길어지는 것을 좋아하지 않는다. 그러나 기존의 공연장, 극장, 도서관 등의 좌석관리 시스템은 개인의 취향에 맞게 자동으로 좌석 배치를 할 수 없으며 누구나 동일한 정보만 제공하여 준다. 본 논문에서는 이러한 문제점을 개선하기 위하여 개인의 취향에 맞게 즉 신체적인 조건이나 개인의 성향에 맞는 좌석을 지능적으로 배치하고, 선호하는 정보만을 제공할 수 있는 시스템을 제안한다. 제안한 시스템의 성능 확인을 위하여 임의의 극장 좌석 배치도를 이용하여 실험을 한 결과 우수한 성능을 보이는 것을 확인하였다.

The methods of the geometric reconstruction and sensor calibration of satellite linear pushbroom images are investigated. The model of the sensor used is based on the SPOT model that is developed by Kraiky. The satellite trajectory is a Keplerian trajectory in the approximation. Four orbit parameters, longitude of the ascending node(${\omega}$), inclination of the orbit plan(I), latitude argument of the satellite(W) and distance between earth center and satellite, are used for the camera modeling. Time-dependent orbit parameters are expressed by quadratic polynomials. SPOT-5 images have been used for validation tests. The results are that the RMSE acquired from 20 GCPs is 1.763m and the RMSE of 5 checking points 2.470m. Because the ground resolution of SPOT-5 is 2.5m, the result obtained in this study has a good accuracy. It demonstrates that the sensor model developed by this study can be used to reconstruct the geometry of satellite image using pushbroom camera.

The pelvic radiographs of 47 clinically normal Jindoes (26 dogs and 21 bitches) were investigated to evaluate the coxofemoral joints, prospectively. The hip joints were graded according to the Orthopedic Foundation for Animals criteria of excellent, good, fair, borderline, mild canine hip dysplasia (CHD), moderate CHD, severe CHD. Of the 47 Jindoes evaluated, 8 (17%) were graded as dysplastic, 3 (6.4%) were mildly dysplastic, 3 (6.4%) were moderately dysplastic, and 2 (4.3%) were severly dysplastic. Of the 39 Jindoes graded as normal, 16 (34%) were classified as having excellent hip joint phenotype, 15 (31.9%) were classified as having fair, and 8 (17%) were classified as good. Each hip joint was scored based on the British Veterinary Association/The Kennel Club hip scoring system. The normal hip joint (excellent, fair, good) received score less than 5, while dysplastic hip joint (mild, moderate, severe CHD) received score form 5 to 29. Norberg angle (r=0.76) and femoral angle of inclination (r=0.6) were in inverse proportion to grade of the hip joint (P<0.01). The width of medial joint space was in proportion to grade of hip joint (r=0.7, P<0.01).

We fabricated an anode-type ion source driven by a charge repulsion mechanism and investigated its beam shape controlled by a Whenelt mask integrated at the front face of the source. The ion beam shape was observed to vary by changing the geometry of the Whenelt mask. As the angle of inclination of the Whenelt mask was varied from $40^{\circ}$ to $60^{\circ}$, the etched area at a thin film was reduced from 20 mm to 7.5 mm at the working distance of 286 mm, and the light transmittance through the etched surface was increased from 78% to 80%, respectively. In addition, for the step height difference, ${\Delta}$ between the inner mask and the outer mask of ${\Delta}=0$, -1 mm, and +1 mm, we observed the ion beam shape was formed to be collimated, diverged, and focused, respectively. The focal length of the focused beam was 269 mm. We approved experimentally a simple way of controlling the electric field of the ion beam by changing the geometry of the Whenelt mask such that the initial direction of the ion beam in the plasma region was manipulated effectively.

Experimental study has been performed to investigate the influence of non-condensible gas(NCG) charged mass on the thermal performance of a variable conductance heat pipe(VCHP) with screen mesh wick. The VCHP is furnished by screen mesh number 200 for the pipe outer diameter of 12.7mm and the pipe length of 500 mm. The VCHP is filled with water as working fluid of 4.8g and nitrogen as NCG and has evaporator, condenser and adiabatic section, respectively. For the results from experiment, it is found that, for the same charged mass of working fluid, the overall wall temperatures of heat pipe grows up with increasing NCG charged mass. The variation of operating temperature of VCHP reduces with increasing NCG mass. In addition, the profile of axial wall temperature distribution is presented for heat transport capacity of heat pipe, the temperature of cooling water of condenser, inclination angle, and operating temperature.

We studied the polarization state in an apertureless scanning near-field microscopy (a-SNOM) operating in reflection mode by using three-dimensional Finite-difference Time-domain (FDTD) method. As a result, the electric field around tip apex in the near-field region enhanced four times stronger than the incident light for ppolarization when the tip-sample separation was 10 nm. We find that the p- and s-polarization state is maintained for the scattered light when the probe is perpendicular to the sample. When the probe is not perpendicular to the sample, the polarization state of scattered light will rotate an angle that equals to the inclination angle of probe with p-polarization illumination. On the other hand, the polarization state will not rotate with s-polarization illumination.

In this study, orbit determination (OD) simulation for the Korea Pathfinder Lunar Orbiter (KPLO) was accomplished for investigation of the observational arc-length effect using a sequential estimation algorithm. A lunar polar orbit located at 100 km altitude and $90^{\circ}$ inclination was mainly considered for the KPLO mission operation phase. For measurement simulation and OD for KPLO, the Analytical Graphics Inc. Systems Tool Kit 11 and Orbit Determination Tool Kit 6 software were utilized. Three deep-space ground stations, including two deep space network (DSN) antennas and the Korea Deep Space Antenna, were configured for the OD simulation. To investigate the arc-length effect on OD, 60-hr, 48-hr, 24-hr, and 12-hr tracking data were prepared. Position uncertainty by error covariance and orbit overlap precision were used for OD performance evaluation. Additionally, orbit prediction (OP) accuracy was also assessed by the position difference between the estimated and true orbits. Finally, we concluded that the 48-hr-based OD strategy is suitable for effective flight dynamics operation of KPLO. This work suggests a useful guideline for the OD strategy of KPLO mission planning and operation during the nominal lunar orbits phase.
