A case of huge ovarian cyst in 45 years old multiparous woman is presented with a brief review of literatures. This woman was admitted to our clinic with the complaints of marked abdominal distention which progressed rather rapidly: during recent two years. The woman was operated upon abdominally by the author. The tumor was removed surgically after puncture aspiration of the cystic contents before and during the operation. The tumor weight was 29.5 kg. and the volume' of cystic contents were about I1 L. Microscopic sections showed multiloculated mucinous cy stadenoma of the left ovary. The postoperative condition was uneventful and the patient was discharged on the tenth postoperative day.
Fully Collusion-Resistant Trace-and-Revoke Scheme in Prime-Order Groups
박종환,이현숙,이동훈 한국통신학회 2011 Journal of communications and networks Vol.13 No.5
A trace-and-revoke scheme is a type of broadcast encryption scheme for content protection on various platforms such as pay-per-view TV and DVD players. In 2006, Boneh and Waters (BW) presented a fully collusion-resistant trace-and-revoke scheme. However, a decisive drawback of their scheme is to require composite-order groups. In this paper, we present a new trace-and-revoke scheme that works in prime-order groups. Our scheme is fully collusion-resistant and achieves ciphertexts and private keys of size O(√N) for N users. For the same level of security,our scheme is better than the BW scheme in all aspects of effi-ciency. Some superior features include 8.5 times faster encryption,12 times faster decryption, and 3.4 times shorter ciphertexts. To achieve our goal, we introduce a novel technique where, by using asymmetric bilinear maps in prime-order groups, the cancellation effect same as in composite-order groups can be obtained.

This paper investigates the dark side of religious ritual/worship with some critical distance and perspective on ritual performance. This paper focuses on the ritual experience in the Sunday worship setting, by looking at the ritual experience critically and suspiciously in order that its social effects and implications may be exposed. Since the religious ritual in many Christian education settings, including Christian liturgy, misrepresents our social and personal experience; our own convictions often mask the truth which is supposed to be conveyed in the liturgical experience. These are the reasons we have to carefully observe ritual gestures and words that cause the teacher/pastor to manipulate the performance in positive and negative ways in the name of religious tradition. Using Ricoeur’s “hermeneutic of suspicion”, ritual performance should be examined not to support the very foundation that makes possible specific prejudice or ideology, but because the ritual performance often gives more power to this consciousness. Thus, taking ritual seriously means being prepared to critique the theological and ecclesiastical establishments and their one-sided emphasis on doctrinal meaning and efficacy. For this purpose, this paper explores the relationship of ritual performance to power and authority, and traces ritual efficacy in perpetuating traditional authority. Since the power is not morally neutral, ritual performance functions in the production of concentrations of power which are very dangerous. In this paper, the views of several scholars on the meaning of ritual and its relationship to efficacy are examined in order to show how and why their approaches to the meaning of ritual simplify the complexity of ritual practices with their manifold efficacies.
