In conventional diagnostic ultrasound strain imaging, when displaying strain image on a monitor, human visual characteristics are utilized such that hard regions are displayed as dark and soft regions are displayed as bright. Thus, hard regions representing tumor or cancer are displayed as dark, decreasing the contrast inside the lesion. Because the lesion area is stiff and thus displayed as dark, a method of inverting the image brightness and thereby increasing the contrast in the lesion for better diagnostic purposes is proposed wherein a postcompression signal is extended in the time domain by a factor corresponding to the reciprocal of the amount of the applied compression using a technique termed globally uniform stretching. Experiments were carried out to verify the proposed method on an ultrasound elasticity phantom with radio-frequency data acquired from a diagnostic ultrasound clinical scanner. It is found that the new method improves the contrast-to-noise ratio by a factor of up to about 1.8 compared to a conventional strain imaging method that employs a reversed gray color map without globally uniform stretching.

Wet noodles with different percentages of amaranth powder were prepared and their cooking characteristics were evaluated. The cooking quality, mechanical textural properties, and a sensory evaluation was conducted with the prepared noodles. Cooked noodle properties, weight, and volume decreased as amaranth content of the wheat flour increased, whereas turbidity and water absorption of the soup increased, except for cooked noodles with 30% amaranth. The L-value of the raw and cooked noodles decreased significantly with increasing amaranth powder content. The a- and b-values increased with increasing amounts of added amaranth powder. The L-value of the raw and cooked noodles with amaranth was significantly lower than that of the control, and the a-value was lower than that of the control, whereas the b-value was higher than that of the control for both raw and cooked noodles. A texture profile analysis of the raw noodles showed significantly higher levels of hardness, cohesiveness, gumminess, chewiness, and springiness in the amaranth noodles compared to those in the control; the values for adhesiveness were not significantly different. The hardness, gumminess, springiness, and chewiness of the cooked noodles decreased in proportion to the quantity of added amaranth. The springiness, adhesiveness, and cohesiveness of cooked noodles with amaranth decreased slightly. Overall, the results of a sensory evaluation revealed that the cooked noodles with amaranth had higher values than those of the control, except for overall acceptability. Amaranth added at a concentration of up to 30% increased brown color and the peculiar amaranth odor. In a sensory evaluation, cooked noodles with 20% amaranth powder were preferred more than the other noodles for overall acceptability.

Purpose: To evaluate the results and prognosis of operative repair to acute rupture of achilles tend on associated sports injury. Materials and Methods: 21 cases were surgically treated and average follow-up period was 1 year and eight months. The forth decade was most common with $55\%$ and soccer was most common in sports with 5 cases. End-to-end suture of ruptured achilles tendon was performed, and paratendinous structure was wrapped sufficiently. Postoperatively. ankle was plantarflexed for 6 weeks with longleg cast. And then 2 weeks interval, short leg cast with equinous position was conversed to functional position. About 10 weeks after operation, ankle was recovered to right angle. Hooker scale was used to evaluate the results. Results: Compared to normal side, heel-floor distance of ruptures side was decreased 0.7 cm in average, and 0.8 cm was deceased after 20 times weight loaded dorsiflexion. Mid-calf circumference was deceased 0.3 cm, and active dorsiflexion and plantar flexion of ankle was decreased each 3 and 5degree. 16 cases showed ‘excellent’result and 5 cases showed ‘satisfactory’. There was no complication, such as re-rupture or infection at operation site. Conclusion: After end-to-end operative repair to achilles tendon, sufficient wrapping of paratendinous structure is efficient for healing and prevention of postoperative adhesion. And serial dorsiflex-ion cast change is considered to be a successful treatment for preventing residual equinus deformity.

혈관의 안쪽 막인 내막에 콜레스테롤이 침착하고 세포 증식이 일어나면 죽종이라는 것이 만들어진다. 내부는 죽처럼 물러지고 그 주위는 단단한 섬유성 막인 경화반으로 둘러싸이게 되는데, 이를 죽상경화라고 한다. 이렇게 불안정한 경화반이 파열되어 혈관 안에 혈전이 생기고 혈관이 급격하게 좁아지거나 막히는 현상을 죽상동맥경화증이라고 한다. 죽상 동맥경화증은 질병으로 나타나기 전까지는 증상이 없으므로 예방이 중요하다.

외국 사람들에게 독일 자기네의 기술을 주지 않으려는 느낌을 종종 받았지만, 우리는 그들의 것을 보면서 흡수해야만 한다. 필요한 측정기계들은 직접 만들어 사용하는 자세, 옛 것을 중히 여기는 마음, 빠진 보도 블록을 아주 잘 다진 후에 무릎을 꿇고 단단하게 박아넣는 그들의 성실함과 강한 책임감, 대학 연구소에서의 체계화 이룬 일의 처리, 동료들간 협조로써 모든 일을 수행하는 협동심, 연구결과를 잘 정리 보존하는 정리 정신 등을 우리는 보아야 할 것이다.

녹색성장은 저탄소 및 녹색산업화에 기반을 두고 경제성장력을 증대시키는 신성장 개념이다. $CO_2$ 발생량을 줄이고, 녹색기술, 친환경적 비즈니스를 신시장을 창출함으로써 경제성장의 원동력을 확보한다는 것이다. 이때 녹색산업이 투자 가치면에서 얼마큼 큰 부가가치를 발생할지는 예상하기 어렵지만, 단단한 시나리오를 준비하고 투자해나간다면 미래 성장원동력으로 자리할 것이다.
