Region of interest (ROI) is the most informative part of a medical image and mostly has been used as a major part of watermark. Various shapes ROIs selection have been reported in region-based watermarking techniques. In region-based watermarking schemes an image region of non-interest (RONI) is the second important part of the image and is used mostly for watermark encapsulation. In online healthcare systems the ROI wrong selection by missing some important portions of the image to be part of ROI can create problem at the destination. This paper discusses the complete medical image availability in original at destination using the whole image as a watermark for authentication, tamper localization and lossless recovery (WITALLOR). The WITALLOR watermarking scheme ensures the complete image security without of ROI selection at the source point as compared to the other region-based watermarking techniques. The complete image is compressed using the Lempel-Ziv-Welch (LZW) lossless compression technique to get the watermark in reduced number of bits. Bits reduction occurs to a number that can be completely encapsulated into image. The watermark is randomly encapsulated at the least significant bits (LSBs) of the image without caring of the ROI and RONI to keep the image perceptual degradation negligible. After communication, the watermark is retrieved, decompressed and used for authentication of the whole image, tamper detection, localization and lossless recovery. WITALLOR scheme is capable of any number of tampers detection and recovery at any part of the image. The complete authentic image gives the opportunity to conduct an image based analysis of medical problem without restriction to a fixed ROI.

본 연구에서는 베이비붐 세대 부모의 부양기대와 그들의 에코붐 세대 자녀의 부양 의식을 비교하고, 그들의 부양기대 및 부양의식에 영향을 미치는 요인이 무엇인지 알아보고자 하였다. 이를 위하여 서울, 인천, 충남 지역에 거주하는 베이비붐 세대 부모와 에코붐 세대 자녀 228쌍을 대상으로 설문조사를 실시하였다. 분석을 통해 나타난 주요결과는 다음과 같았다. 첫째, 베이비붐 세대의 부양기대는 모두 중간 수준이었고, 정서적 부양기대, 신체적 부양기대, 경제적 부양기대 순으로 나타났다. 둘째, 에코붐 세대의 부양의식은 전반적으로 높은 수준이었으며, 신체적 부양의식, 경제적 부양의식, 정서적 부양의식의 순이었다. 셋째, 경제적 부양, 정서적 부양, 신체적 부양 모두에서 에코붐 세대의 부양의식이 그들의 베이비붐 세대 부모의 부양기대보다 높았다. 넷째, 부양기대에 대한 다중회귀분석 결과, 경제적·정서적·신체적 부양기대에 공통적으로 가장 큰 영향력을 갖는 변인은 자녀와의 친밀감이었다. 다섯째, 부양의식에 대한 다중 회귀분석 결과, 에코붐 세대의 부양의식에 영향을 미치는 가장 중요한 요인 역시 부모 와의 친밀감이었다. 이러한 결과에 근거하여 향후 베이비붐 세대의 노화에 대비하여 노인부양 정책 마련과 부양 교육 프로그램 개발 등에 관련한 제언과 후속연구를 위한 제언을 덧붙였다. The purpose of this research was to compare the support expectation of baby boomer parents with the support consciousness of echo-boomer children, and further, examine the effect of intimacy on both their support expectation and support consciousness. The survey was conducted for 228 pairs of baby boomer parents and their echo-boomer children living in Seoul, Incheon, and Chungcheong-Do. The results of this study were as follows: ① The baby boomers support expectation was midium level, and was high in the order of emotional, physical, and economic support expectation in detail. ② The echo-boomers’ support consciousness was high level, and was high in the order of physical, economic, and emotional support expectation in detail. ③ The echo-boomers’ support consciousness was higher than their baby boomer parents’support expectation in all of economic, physical, and emotional support. ④ As the result of the multiple regression analysis, the most effective factor on economic, physical and emotional support expectation of the baby boomers was the intimacy with their children. ⑤ As the result of the multiple regression analysis, the most effective factor on the support consciousness of the echo-boomers was the intimacy with their parents, as well. Some suggestions were made based on the results of research above.

This study investigated the effect of moderate exercise training on macrophage immunocompetence in high fat diet-induced obese mice. To determine the differential effects of exercise training and low fat diet on macrophage, C57BL/6 male mice (4 week old, n=32) were fed high-fat diet for 5 weeks to induce obese. The high fat-induced obese mice were then divided into four groups and differently treated by high/low fat diet and exercise training for a further 8 weeks; HHC (13 weeks high-fat diet), HHE (13 weeks high-fat diet with 8 weeks Exercise training) and HLC (5 weeks high-fat diet and 8 weeks low-fat diet), HLE (5 weeks high-fat diet and 8 weeks low-fat diet with exercise training). The exercise groups were performed on a motorized treadmill, running for 30-60 min/day at 10-22 m/min, 0% grade for 8wks. Body weight was significantly decreased for those with a low-fat diet and exercise training (HLE). Macrophage phagocytosis was significantly increased by low-fat diet and exercise training (HLE). The percentage of stimulation of NO release induced by LPS was higher in HLE than in other groups. The percentage of stimulation of IL-1β release induced by LPS was higher in HHE and HLE than in other groups. The percentage of stimulation of IFN-γ release induced by LPS was higher in HLE than in other groups. These findings suggest that moderate exercise and low-fat diet have beneficial effects on macrophage immunocompetence in high fat diet-induced obese mice.

희곡의 한 형태로서 희극 : 주로 Shakespearean Comedy를 중심으로 Chiefly on Shakespearean Comedy

崔京蘭 단국대학교 1983 論文集 Vol.17 No.-

Division of Shakespeare's plays into comedies, tragedies, and histories is somewhat arbitrary, for Shakespeare himself did not make the division we observe today. First of all, it is very difficult to define the meaning of comedy. Most definitions of comedy go back to Aristotle's Poetics. Since Aristotle we have been accustomed to think of comedy as drama concerned with the ridiculous in human nature and ending happily; of tragedy as drama of man's nobility, ending unhappily. But a story beginning in sadness and ending in happiness can hardly be an adequate essential quality of Shakespearean comedy. Shakespearean comedy is an Elizabethan type of comedy. However, it differs from Elizabethan drama. It is commonplace to speak of the different kinds of Shakespearean comedy. Shakespeare comedy is usually divided into four categories-early comedies, festive comedies, dark comedies, and romances. Each of these categories has its own characteristics. Especially Shakespeare's two plays, All's Well That Ends Well and Measure for Measure, are called 'dark comedies' or 'problem plays'. The lovers in these two plays do not show as much delight as the lovers in the earlier comedies. However, the plays end well as a result of skillful planning called 'bed-trick', and those characters who had hated each other are reconciled. The impression that remains, however, is one of sadness and disillusionment. Shakespeare's last plays written between 1608 and 1611 Cymbeline, Pericles, The winter's Tale, and The Tempest are called romances by critics. These plays are concerned with wonderful actions that cover a long period and are full of findings as well as losses, reconciliation and forgiveness. The dominant motif in these four plays is the restoration of losses.
