언샤프 마스킹 기법은 회색조 영상의 화질 향상을 위해 널리 사용되는 영상 강화기법 중 하나이다. 하지만 언샤프마스킹 알고리즘은 노이즈에 민감하며 오버/언더슛이 발생하여 영상을 열화시키는 문제가 있다. 또한 칼라 영상성분에 기존 알고리즘을 그대로 적용하게 되면 영상에서 색차의 왜곡현상이 발생한다. 이러한 여러 가지 문제를 해결하기 위하여 본 논문에서는 고급 언샤프 마스킹 알고리즘을 사용하여 색차왜곡 없이 영상의 경계를 강조하고 노이즈와 오버/언더슛 문제를 해결한다. 제안하는 알고리즘은 오버/언더슛과 노이즈 문제를 해결하기 위하여 인간의 시각적 특성과 영상의 지역적 색차 대비 특성을 이용하여 영상 강화의 단계를 조절하고, RGB영상과 HSI영상의 관계를 바탕으로 RGB의 벡터적 특성에 기반한 투사 방법을 이용하여 색차왜곡을 방지한다. 실험 결과는 제안하는 알고리즘이 성공적으로 경계 영상을 강조하는 동시에 타 알고리즘을 적용했을 때 발생하는 색차왜곡과 노이즈 및 오버/언더슛 현상 없이 영상이 강조된다는 것을 확인할 수 있다. Unsharp masking is a popular image enhancement technique used to sharpen an image appearance in gray images. However, the conventional unsharp making techniques amplify the noise and easily cause overshoot artifacts. Moreover, the unsharp masking tends to introduce color distortion when it is applied to the each color component independently. To solve these problems, we propose a novel unsharp masking technique based on human visual system and vector projection. The proposed algorithm consists of two steps. First, the proposed algorithm controls the level of sharpening by exploiting the characteristics of the human visual system and contrast region. Then the vector projection is applied to remove the color distortion. Experiment results show that our proposed algorithm successfully produces sharpened images that are free of noise and color distortion commonly found in the conventional unsharp masking algorithms.

This study obtained the results through the integrative literature reviews about the effect of laugh activity which is an important trend of health and success in the modern society in order to provide the theoretical basis. The study results are as followings: First, laugh activity starts from the rehabilitation that is based on the treatment of Hippocrates, which treats both body and mind. Currently, many hospitals, schools, and enterprises use laugh for giving the vitality of life. Second, laugh activity makes the body and the mentality healthy, enhances life quality and contributes to the happiness of man. It is desirable that we start from soft laugh and increase it little by little under the sequence of a small laugh and a big laugh. In addition, since the contraction and relaxation of a muscle, and flexibility of the joint are necessary for laugh, laugh activity which is fit for our physical strength is needed. Third, laugh activity is revealed to have the physical and psychological effect. In other words, it is evident that laugh activity is truly required for improving health, overcoming the adversity, and maintaining happy life.

“신극”의 지속을 위한 모색과 화두로서의 “중간극”

이광욱 ( Kwang-ouk Lee ) 서울대학교 인문학연구원 2016 人文論叢 Vol.73 No.2

본고는 1930년대 후반기 조선연극계의 화두로 부각되었던 ‘중간극’이 불러온 담론의 양상을 밝히고자 한 연구이다. ‘중간극’은 일본에서발생한 절충적 연극을 가리키는 개념이었으나, 박영호가 논의한 ‘중간극’은 오히려 일본의 신협극단에서 표방한 ‘신극의 대중화’ 노선과 유사한 것이었으며, 이와 같은 경향은 2기 활동에 접어든 극연의 행보와도 일맥상통한다. 한편 극연은 ‘중간극’에 대해 애매한 자세를 취할 수밖에 없었는데, 이는 ‘신극’이라는 기호에 내재된 문화자본을 유지하는것이 극연의 기존 관객층이던 지식인들을 결집시키는 방법이었기 때문이다. 더욱이 ‘신극’이 지닌 가치는 흥행극과의 ‘구별짓기’를 통해 구성된 것이었으므로, 극연은 중앙무대의 공연이 흥행극에 불과하다고 비판하지 않을 수 없었다. 그러나 극연의 문화자본 독점에 대한 불만이 제기되는 가운데, 신극과 중간극의 실질적 차이를 발견하지 못하게 되자, 신극의 외연은 중간극을 포함한 ‘신극계’로 확장되게 되었다. 더 나아가 신극 진영은 중간극에 대한 입장 차이를 계기로 삼아 점차 분화되기도 했다. 이후 중간극이라는 용어는 점차 담론장에서 사라지게 되지만, 그 문제의식은 ‘신극의 매력’이라는 용어로 이어지게 되었다. 이는 1930년대 후반에 이르러 관객들의 계층이 혼합되는 경향을 보이게 된 것과 관련되는데, 상업성을 기준으로 신극과 흥행극을 구분지어 왔던 기존의 분법적 논리는 결국 유효성을 상실하게 된다. 즉, 신극은 스스로의 가치를 실증해야 하는 과제를 떠안게 되었던 것이다. 그렇다면 이 시기에 산출되었던 이론비평들은 신극의 지속을 위한 진지한 모색이라는 점에서 주목해볼 필요가 있을 것이다. This study tries to elucidate the discourses brought on by the ‘middle-theater’ that appeared as an agenda for the Chosun theatrical world in late 1930’s. The middle-theater referred to the eclectic theatrical works appeared in Japan. But Park`s claim for middle-thater was similar to the popularized way of the Shin-hyup and the second period of the Keuk-yeon. Meanwhile, the Keuk-yeon had no option but to take a doubtful position about middle-theater. This is because the maintaining the cultural capital included in the sign ‘new-drama’ was a way to unify the existing audience of the Keuk-yeon - the intellects. Moreover, as the value of the new-drama had been formed through a distinction from commercial plays, Keuk-yeon could not help denounce the play of Chungangmudae as nothing but a commercial play. But there were complaints about the monopolistic cultural capital of the Keuk-yeon, and it was hard to identify an actual difference between new-drama and middle theater. Therefore, the extension of new-drama was expanded as new-drama world that included the middle-theater group. Moreover, the new-drama group had become gradually differentiated in adopting different position about middle-theater. Afterwards, the term of middle-theater disappeared from the field of discourse, but it’s critical consciousness was succeeded by the term ‘attraction’ of the new-drama. This had relevance to the audience pool that displayed a tendency of a class mixing. Finally, the existing dichotomy to divide new-drama and middle-theater according to commercialism was no longer useful in late 1930’s. In other words, the new-drama group was given the task of proving its value of existence. Therefore, focus must be centered around the fact that the theoretical criticism produced at this time was the result of earnest effort to find the survival plan of new-drama.

Google의 새로운 개인정보정책의 법적 문제점

이광욱(Kwang-Wook Lee) 서울대학교 법학평론 편집위원회 2012 법학평론 Vol.3 No.-

개인정보의 경제적 가치가 중요하게 됨과 비례하여 개인정보의 유출 등 침해 사고도 빈발하고 있고, 정보주체의 개인정보에 대한 권리 침해 가능성도 증대되었다. 이러한 배경 아래 우리나라에서도 2011. 9. 30. 개인정보 보호에 관한 일반법인 「개인정보 보호법」이 시행되었고, 2012. 4. 1.부터는 본격적으로 시행되고 있다. Google의 새로운 개인정보 정책의 문제점을 다루는 이 글은 위와 같은 사회적, 경제적, 법제적 배경 아래 Google이라는 거대 IT 기업의 개인정보 정책의 변경이 정보주체에 대하여 어떠한 권리침해 등 법적 위험을 가져올 수 있는지를 살펴보고, 이를 어떻게 규제할 것인지 고민해 보는 의도에서 작성되었다. Google의 새로운 개인정보 정책은 「개인정보 보호법」과 「정보통신망 이용촉진 및 정보보호 등에 관한 법률」에서 정한 개인정보 취급방침에 관한 사항, 목적 외 이용 금지, 최소수집원칙 등 개인정보 보호 원칙, 동의 절차 등 규정과 「약관의 규제에 관한 법률」을 위반하였거나 부합하지 않고, Google 서비스 이용자의 자기정보결정권 등 권리를 침해할 가능성이 있다. 현행 법의 한계 등으로 규제 기관이 제대로 된 규제를 하고 있지 못하고 있으나, 향후에는 적극적인 법 해석으로 정보주체의 권리보장에 부족함이 없는 조치가 있기를 기대해 본다. As the significance of the economic value of personal information has increased, occurrences of leakage and infringement of personal information have also increased, and, this in turn has also increased the likelihood of infringing upon the rights of the data subject. Under such circumstances, the Personal Information Protection Act (the “PIPA”), which is a general law that protects personal information, became effective as of September 30, 2011 in Korea and, as of April 1, 2012, the PIPA is being fully implemented. This article which deals with issues regarding Google’s new privacy policy, examines the risks of infringing upon the rights of the data subject and legal risks which are faced under the societal, economic and legal background noted above and explores possible methods to regulate the above. Google’s new privacy policy either violates or is inconsistent with the regulations of the PIPA and the Act on Promotion of Information and Communications Network Utilization and Information Protection with respect to matters such as policies for handling personal information, prohibition of use beyond the purpose of collection, principle of collecting the minimum amount of information necessary, the principle of protecting personal information and the procedures for obtaining consent. Moreover, Google’s new privacy policy also violates or is inconsistent with the Regulation of Standardized Contracts Act and may violate the right to decide matters by Google service user regarding his/her information. While the applicable authorities are limited in regulating the above due to, among other factors, limitations under the current laws, it is possible that sufficient measures to protect the rights of the data subject could be made through active interpretation of the laws.
