In this paper, we proposed a technique for minimizing blocking effects and mosquito noises which are major causes of image degradation in H.263-based transmitted images. Since the blocking effects occur in the uniform region like background and the mosquito noises occur in the non-uniform rigion like edge neighborhood, we proposed an algorithm to divide image into uniform and non-uniform regions and a filtering algorithm that is adequate for each noise. To reduce the blocking effects, 4-pixel non-linear filter is proposed to get the better performance in both subjetive and objective respect. 5-pixel median filter is used for reducing mosquito noises. In simulation result, the proposed method shows higher PSNR of 0.02~1.01dB and better subjective test, results in comparison with existing methods.

특수형 방사성물질 운반캡슐은 국내외의 수송관련 법규에 규정된 기술기준을 만족하도록 설계, 제작되어야 한다. 본 연구의 목적은 하나로에서 생산된 192Ir 특수형 동위원소 운반캡슐의 건전성을 평가하는데 있다. 법규에서 규정된 낙하시험, 타격시험, 굽힘시헝 및 가열시험조건에 대한 안전성 시험을 수행하였으며, 각각의 시험 전후에 누설시험을 수행하였다. 또한, 안전성시험과 더불어 컴퓨터코드를 이용한 전산해석을 수행하여 안전성시험 전에 시험결과에 대한 예측자료로 활용되었다. 낙하시험 및 가열시험 결과 캡슐 표면에서 약간의 흠집과 변형이 발생하였으나, 각각의 시험에서 평가기준이 되는 캡슐의 손상이나 용융 등은 발생하지 않았다. 또한 각 시험 후 수행한 누설시험 결과 누설이 발생하지 않았다. 따라서 특수형 방사성물질 운반캡슐은 법규에서 규정하는 기술기준을 만족하도록 설계, 제작되었음이 입증되었다. All of sealing capsules to transport a special form radioactive material should be designed and fabricated in accordance with the design criteria prescribed in IAEA standards and domestic regulations. The objective of this study is to demonstrate the safety of a shipping capsule for 192Ir special form radioisotope which produceed in the HANARO. The safety tests were carried out for the impact, percussion, bending and heat test conditions. And leakage tests were carried out before and after the each test. Also, the safety analyses were performed using computer codes in order to verify the test results. The capsule showed slight scratches and deformation, and maintained its structural and thermal integrities in all tests without any severe damage or melting. It also met the allowable limits of leakage rate after earth test. Therefore, it has been verified that the capsule was designed and fabricated to meet all requirements for the special form.

The purpose of this study was to determine the physical performance take BAE-ESCARGOT. This study were obtained from pretest (before test) to posttest (after 4 weeks test) and graded exercise by ergometer. Subjects were 7 males elite athletes. BAE-ESCARGOT to be taken three times a day after each meal. Results were as follow: 1. BAE-ESCARGOT don't delaied exercise time (P<0.05). 2. BAE-ESCARGOT don't increased exercise capacity (P<0.05). 3. BAE-ESCARGOT were significant from swimming and 100rm record (P<0. 05). 4. BAE-ESCARGOT were significant from VO_2 max but were not insignificant from heart rate (P<0.05). 5. BAE-ESCARGOT were not accumulated from vein lactate and capillary lactate (P<0.05). 6. BAE-ESCARGOT were increased of CK from exercise capacity (P<0.05).
