Lower right first and second molar missings were restored by unilaterally designed removable partial denture, not to disturb the phonetic function. Terminal abutment teeth were splinted and ASC52 attachment aws used as a direct retainer. After that, oral examination and Roentgenographic examination were done periodically for 2 years. There were no remarkable changes on the abutment teeth and its surrounding structures. Also, there no phonetic disturbances by the appliance.

The electrical characteristics of 3 year field-aged polymer insulators which dismounted from five regions were investigated. There was a little difference in PD inception voltage depending on the manufacturers and the regions. The results between PD and SD showed a close relation. There were no significant changes in electrical properties. So, it can be considered that the field-aged insulators are sound for the present.

If the completely observed data are assumed to have full information, the censoring causes the loss of information. Previous studies have introduced the indices of information loss via measuring relative changes between the data with censoring and without censoring. In this paper, the comparisons are made for the information loss between type I and type II censoring in two sample problems.

The effects of partial replacement of flour with isolated soy protein (ISP) on sponge cake quality were investigated. The replacement did not cause any significant changes in physical characteristics of sponge cakes including specific gravity, specific volume and expansion ratio. As the level of ISP replacement increased, the sponge cakes were darker in color, harder, chewier and drier than control groups. The textural characteristics (hardness, cohesiveness, springiness, gumminess and chewiness) of the sponge cakes also increased as the level of flour replacement increased. Up to 15％ of the flour could be replaced by ISP without diminishing the sponge cake quality.

목적: 관절경을 이용한 반월상 연골 절제술 후의 슬관절의 임상적 및 방사선학적 변화를 알아보고자 한다. 대상 및 방법: 1990년 10월부터 1992년 9월까지 반월상 연골의 손상으로 본원에서 슬관절의 관절경적 시술을 시행 받은 144명의 환자 중 $10\sim15$년 뒤 장기 추적이 가능했던 79명의 환자를 대상으로 임상적 평가와 체중 부하 슬관절 방사선 촬영을 시행하여 그 변화를 관찰하였다. 79명 중 52명은 남자였으며, 평균 연령은 34.6세$(17\sim48)$였다. 결과: 추시 결과, Fairbank 변화와 관절강 협소를 포함한 방사선학적 변화는 부분 절제술 후 54예 중 23예(42.6%), 전 절제술 후 25예 중 22예(88.0%)에서 발생하여 전 절제술 후 많은 변화를 보였다(p=0.03). 임상적 결과는 부분 절제술군에서 만족이 54명 중 39명(72.4%), 전 절제군에서 25명 중 14명(56.0%)으로 부분절제술 후 만족도가 높았으나 통계적 의의는 없었다(p=0.24). 결론: 반월상 연골 절제술 후의 평균 12년 후 추시 결과, 방사선적 변화는 전 절제술시 크게 나타났으며, 이러한 변화는 슬관절 기능과 활동성에 영향을 미치지 않는 것으로 생각된다.

The purpose of the study is to evaluate the Rural Settlement Development(RSD) driven by government in historical view, and its effects on the facilities and houses of rural village in the country. Through the study, we have come to the results that the major concerns of the RSD projects since 1950s has been transferred to as following. First, the reformation of inter-facility; dressing room, kitchen, bath-house, etc of rural houses, from that of outer facility; roof, fence and etc. Secondly, the substantial objects of the projects of village settlement improvement have been changed from partial reformation of individual houses, public facilities, etc early, to comprehensive reformation by master plan for village settlement recently. Lastly, those have been established that the process of planning village settlement available to carry out landuse division and the various program for village improvement, based on its inherent circumstances.

Specimens of austenitic stainless steel were irradiated with 6 MeV Xe ions to two doses of 7 and 15 dpa at room temperature and 300 ℃ respectively. Then partial irradiated specimens were subsequently thermally annealed at 550 ℃. Irradiation-induced BCC-phase formation and magnetism were analyzed by grazing incidence X-ray diffraction (GIXRD) and vibrating sample magnetometer (VSM). It has been shown that irradiation damage level, irradiation temperature and annealing temperature have significant effect on BCC-phase formation. This BCC-phase changes the magnetic behavior of austenitic stainless steel. The stress relief and compositional changes in matrix are the driving forces for BCC-phase formation in austenitic stainless steel during ion irradiation.

The major problems of recent object tracking methods are related to the inefficient detection of moving objects due to occlusions, noisy background and inconsistent body motion. This paper presents a robust method for the detection and tracking of a moving in infrared animal videos. The tracking system is based on adaptive optical flow generation, Gaussian mixture and Kalman filtering. The adaptive Gaussian model of optical flow (GMOF) is used to extract foreground and noises are removed based on the object motion. Kalman filter enables the prediction of the object position in the presence of partial occlusions, and changes the size of the animal detected automatically along the image sequence. The presented method is evaluated in various environments of unstable background because of winds, and illuminations changes. The results show that our approach is more robust to background noises and performs better than previous methods.

Cotton fabrics were mercerized in ammonia water, sodium hydroxide and mixture of ammonia/sodium hydroxide, slack and under tension. X-ray and infrared spectra analyses were used to measure crystallinity of treated cottons. Changes due to swelling, which took place in the accessible regions were determined by moisture regain and dye adsorption. In addition to that crease recovery was compared mutually, and breaking strength-elongation compared, too. Both ammonia water and caustic treatments produced changes in morphology (swollen fibers, decrease in convolutions) and in fine structure of the cellulose (increase accessibility as measured by increased moisture regain, dye adsorption). X-ray diffraction showed partial recrystallization into cellulose III lattic after tension treatment with ammonia water. Both reagents produced increased cotton elongation-at-break with slack mercerization, increased cotton breaking strength with tension mercerization, and increased moisture regain or dye adsorption with slack mercerization.

Changes in physiological and biochemical patterns in lucerne plants caused by the presence of 'Candidatus Phytoplasma australasia', which is one of the significant pathogens causing yield losses in lucerne plants, were investigated. Significant differences were evident in total chlorophyll, chlorophyll a, chlorophyll b, and protein amounts between 'Ca. Phytoplasma australasia'-positive and negative lucerne plants. Stress-related metabolites such as phenol, malondialdehyde, and proline accumulations in 'Ca. Phytoplasma australasia'-positive plants were remarkably higher than those of phytoplasma-negative plants. As a response to disease attack, phytoplasma-positive plants exhibited higher antioxidant enzymes (peroxidase and catalase) and nonenzymatic metabolite responses such as jasmonic and salicylic acids. We state that partial disease responses were revealed for the first time to breed resistant lucerne lines infected by 'Ca. Phytoplasma australasia'.
