In a backlash against corporate branding and capitalism, a growing number of consumers are resisting current marketplace practices and big corporate brands. One particular form of this phenomenon is the emergence of anti-brand communities in social media. The current study, which surveyed a sample of 251 anti-brand community members on Facebook, provides a preliminary understanding of the characteristics and antecedents of anti-brand communities as a new platform for consumer empowerment and anti-brand activism. Findings suggest that consumers' engagement in online anti-brand communities, especially through social media, may be triggered by their negative experiences with employees, product quality, post-purchase service, and value/price. They are motivated, the results show, by seven primary factors: altruism, revenge, advice seeking, convenience, sympathy seeking, socialization, and the need to vent.

This paper is intended to explore femininity the ideal beauty of body and the features in fashion pursued in the Fashion system and the Anti-Fashion Movement in the Victorian period, on which the modern fashion is based. For the informative facts needed in this paper, books on history, fashion history, feminism, art history of aestheticism and the ideal beauty of body are referred to. On the part Ⅱ of this paper, the femininity and the ideal beauty of body implied in the Aesthetic Movement and Rational Dress Movement as the anti-fashion movement in the Victorian period will be reviewed. Following are the conclusion : First, the works in Aesthetic Movement mainly include the image of sensual female. The essence of femininity is categorized by cultural value, poetic spirit. appetite for sex and self-expression. The ideal beauty of body pursued in this movement is the beauty of immatured body, which means rejection of maternity as well as appetite for sex in the form of metaphor of the power and enthusiasm of female. The features of Aesthetic Movement emphasize the image of sensual and characteristic woman. These features are expressed in the natural waist line and the vertical H silhouette of high waist, natural exposure of body by means of drapery, simplicity and decency by design without fixed forms and seemingly faded colors. Second, Rational Dress Movement attempted to evaluate the femininity in a different way and ultimately pursued masculinity. Therefore, morality, liberty, intelligence, spirituality, self-control, willingness, which had been believed to exclusively belong to male, are added to the categories of femininity. The ideal beauty of body is expressed in the form of Venus Coelestic which is refined and strong. This symbolizes woman's freeing from the fate of reproduction and subordinate relationship with male, morality, decision of one's own and willingness. The features of Rational Dress Movement represent the image of strong-willed and moral woman in its internal meaning. The features of its fashions represent the concealment of the body, emphasis on activeness in pants without decoration and simplicity in its external form. All these features resulted from the pursuit of masculinity.

본 연구에서는 적분변환에 의한 해법을 사용하여 폐형으로 주어지는 엄밀해를 얻었다. 먼저 평면에 수직한 방향의 변위를 도입하여 주어진 문제를 Mellin 변환하 고 수식화 하면 Wiener-Hopf 방정식이 주어진다.이 방정식을 푼 다음 변위에 관한 적분 표현식을 점근(asymptotic)전개하여 평가하면 균열선단 부근의 변위가 결정된다. 이로부터 폐형(closed form)으로 구성되는 균열선단부근의 응력확대계수(stress in- tensity factor)를 얻었다. 이 결과를 가지고 특정한 경우에 해당되는 기존의 연구 결과와 비교하였다. 특별히 가해진 하중이 자기평형(self equilibrium)을 이루는 경 우에 한정하여 계면에 인접한 재료의 결과와 동일함을 무한고체물에 대한 해석에서 보 인 바 있는데, 이와같은 정성적인 결과가 본문제와 같이 계면방향 표면균열을 지니는 반무한 크기의 고체물에서도 유지되는가를 검토하였다. 아울러 본 연구와 동일한 모 양의 균열이라면 고체물표면 혹은 균열면에 임의로 분포하는 비평면하중문제에 대한 응력확대계수는 본 연구의 결과를 가지고 간단한 적분을 수행함으로써 용이하게 계산 됨을 보였다.

Objectives: The purpose of this study is to evaluate anti-breast cancer and anti-inflammatory effects of Chungganhaewool-tang and Shipyeukmiyeugi-eum. Methods: MDA-MB-231 cells were used to measure cytotoxicity, Reactive oxygen species (ROS) production, protein expression amounts of Bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xl), Cytochrome C Caspase-3, Caspase-7, Caspase-9, Poly ADP-ribose polymerase (PARP), Nuclear factor erythroid-2-related factor 2 (Nrf2), Heme oxygenase-1 (HO-1) and NAD (P) H Quinone Oxidoreductase 1 (NQO1) to evaluate the anti-breast cancer effects of Chungganhaewool-tang (CHT) and Shipyeukmiyeugi-eum (SYE), and THP-1 cells, differentiated into macrophage and induced inflammation with Lipopolysaccharide (LPS), were used to measure production amounts of ROS, Nitric oxide (NO), and protein expression amounts of Inducible nitric oxide synthase (iNOS), Cyclooxygenase (COX-2), Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6) and Tumor necrosis factor-alpha (TNF-α) to evaluate the anti-inflammatory effects of CHT and SYE. Results: CHT and SYE reduced MDA-MB-231 cell counts, increased protein expression of Bax and Cytochrome C, and decreased protein expression of Bcl-2, Bcl-xl. The protein expression amounts of Caspase-3, 7, and 9 decreased, but amounts of the active form, cleaved Caspase-3, 7, and 9, increased. In addition, PARP protein expression decreased, the amount of PARP protein in the cleaved form increased, and the amount of protein expressions of Nrf2 and HO-1 decreased, but NQO1 showed no significant difference. In THP-1 cells CHT and SYE reduced ROS and NO, and reduced protein expressions of iNOS, COX-2, IL-1, and TNF-α, but only SYE groups reduced IL-6. Conclusions: This study suggests that CHT and SYE have potential to be used as treatments for breast cancer.

최근의 인터넷 공격의 화두는 네트워크의 트랙픽을 이용한 분산 서비스 거부 (DDoS : Distributed Denial of Service) 공격이다. 정부 기관과 기업들은 DDoS 공격을 막기 위한 대응책으로 DDoS 방어 전문 장비인 Anti-DDoS SW를 도입하고 있다. 하지만 현재 Anti-DDoS의 객관적인 품질평가 기준이 없어 Anti-DDoS SW를 개발한 회사들이 제시하는 객관적이지 않은 정보에 의존하여 Anti-DDoS SW를 도입하고 있다. Anti-DDoS SW 시장규모가 커지면서 Anti-DDoS SW의 객관적인 품질평가가 요구 되고 있다. 본 논문에서는 DDoS 공격을 막기 위한 Anti-DDoS SW 제품 도입시 고려할 성능평가 요소에 대해 기술하였다.

For the purpose of development of anti-jamming GPS receiver we have developed an anti-jamming algorithm and its Simulink implementation model. The algorithm used here is a form of Space-Time Adaptive Processing (STAP) filter which is well known as an effective way to remove wideband jamming signals. We have chosen Minimum Variance Distortionless Response (MVDR) block-adaptive beamforming algorithm for our development since it can provide relatively fast convergence speed to reach optimal weights, stable and high suppression capability on various types of jamming signals. We will show modeling results for this MVDR type adaptive beamformer and some simulation results. We also show the integrity of the demodulated satellite signals and the accuracy of resulting navigation solutions after anti-jamming operation.

Anti-inflammatory and analgesic activities and skin irritation of piroxicam patch were investigated. Piroxicam patch increased the pain threshold in rat hind paw inflamed by carrageenan and inhibited writhing induced by acetic acid in mice. Piroxicam patch also inhibited the carrageenan-induced edema in rat hind paw as well as the increased vascular permeability induced by histamine in rats. In adjuvant arthritis of rats, piroxicam patch showed anti-inflammatory effects. Skin irritation of piroxicam patch was tested in Newzealand White rabbits and evaluated by Primary Irritation Index of Draize. The results from skin irritation test showed that piroxicam patch seemed practically non-irritating. The result from the present study indicates that piroxicam may be useful without serious side effects as anti-inflammatory analgesics in this patch form.

Distal acquired demyelinating symmetric (DADS) neuropathy is a variant form of chronic inflammatory demyelinating polyradiculoneuropathy. A 54-year-old man presented with gait disturbance owing to weakness in both legs. Nerve conduction studies showed demyelinating sensorimotor polyneuropathy, and laboratory studies demonstrated anti-GM1 and anti-GD1b IgG antibodies, but no anti-myelin associated glycoprotein activity. We suggest that an antiganglioside antibodies assay needs to be applied when DADS neuropathy is suspected in order to improve the classification of dysimmune neuropathies.

The effects of Bi and Te on the anti-galling behaviors of Ni base alloy were investigated by SEM, galling test and wear test. Anti-galling characteristics depended on the structure of matrix and distribution of Bi-rich phase which was precipitated at grain boundary. The addition of 5 wt% Bi markably enhanced anti-galling properties. The addition of Te caused Bi-rich precipitates to disperse finely and casting structure to form equiaxed type. From the above tests, the concentration of 5 wt% Bi and 1 wt% Te was selected to optimize in this alloy.
