Sang-Su Lee et al. 373 This paper presents a new method for a visual cryptography scheme that uses phase masks and an interferometer. To encrypt a binary image, we divided it into an arbitrary number of slides and encrypted them using an XOR process with a random key or keys. The phase mask for each encrypted image was fabricated under the proposed(More)
Ipsec is a standard protocol to offer Internet information security service. Recently Ipsec is implemented through out the world on the base of various operating systems. Through the inter-operability test among multiple independent implemented devices, it is now the mandatory function of Internet equipment. Ipsec adds two headers (i.e.,AH & ESP) and(More)
We herein describe an analytical method employing a small molecule array for the characterization of similar proteins based on ligand binding. In this study, 2 different beta amyloids (Abeta(1-40) and (1-42)) were selected as the model compounds. Their primary structures are identical except for 2 additional C-terminal amino acids. However, many studies(More)
Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferating disease affecting the synovium of joints, bursae, and tendon sheaths. The knee is the most common site of involvement and accounts for up to 80% of cases. Involvement of the shoulder is extremely rare. Only 1 case of involvement of the subacromial space has been reported worldwide. We(More)
