With the development of wearable(ubiquitous) computers, those traditional interfaces between human and computers gradually become uncomfortable to use, which directly leads to a requirement for new one. In this paper, we study on a new interface in which computers try to recognize the gesture of human through a digital camera. Because the method of recognizing hand gesture through camera is affected by the surrounding environment such as lighting and so on, the detector should be a little sensitive. Recently, Viola's detector shows a favorable result in face detection. where Adaboost learning algorithm is used with the Haar features from the integral image. We apply this method to hand area detection and carry out comparative experiments with the classic method using skin color. Experimental results show Viola's detector is more robust than the detection method using skin color in the environment that degradation may occur by surroundings like effect of lighting.

The purpose of this study is to evaluate the differences among visual images under variations in shoulder length and puff volume of the puff sleeve blouse. The stimuli are 21 samples: three variations of shoulder length and seven variations of puff volume. The data has been obtained from 40 fashion design majors, where they had been analyzed through frequency, factor analysis, ANOVA, Scheffe's test and MCA method. The results of the study are as the following: As a result, through factor analysis of the visual images according to the variation of shoulder point and puff volume, the following four factors had been identified. Factor 1 is the brightness from evaluation terms such as childish-precocious, cute-mature, bright-genteel, soft-hard, enlarged-reduced, particular-ordinary, interesting- uninteresting, etc. Factor 2 is the attractiveness from evaluation terms such as refine-rustic, stylish-dull, attractive-unattractive, modern-classic, urban-rural, cool-gloomy, spacious-tight. etc. Factor 3 is the comfortness from evaluation terms such as comfort-discomfort, intense-indistinct, etc. Factor 4 is the elegance from evaluation terms such as elegance-shallowness, womanish-manly, etc. These four factors were 66.7% of the total variables. Of the total variables, the first factor had been evaluated as brightness in 26.2%, attractive in 21.0%, comfortness in 11.1%, and elegance in 8.4%. From this study, the more puff volume and shorter shoulder length, the puff volume wrapped the shoulder naturally, thus making the shoulder look narrow, and giving a cute and bright image. However, by having less puff volume and excessively short shoulder length, the puff volume did not naturally wrap the shoulder, which gave an unnatural and unattractive feel.

Jang, Hyeon-Guang is one of the representative natural philosophers of Joseon Korea. This article aims to investigate the meaning of the factors of Xiangshuxue(象數學) contained in his cosmology. Xiangshuxue applies Image(Xiang), Numeral(Shu) and In-Yang to present the distinctions, inter-relations and time-series orders of things. Jang's cosmology, combined with Xiangshuxue, insisted that Li(Principle) is infinite in time and space, the cosmos is finite on the other side. This assures that the moral principle is absolute and eternal. Jang emphasized the book I-ching as the criterion and the model in understanding the nature. This restrained the objectivizm of Shaoyong and made his concept 'natural law' difficult to change itself as the experience and the knowledge expand. None the less, his cosmology is appraised in that it strengthened natural philosophical basis of neo-confucianism and preceded the cosmological investigations since mid-Joseon dynasty.

Aerial objects are more challenging to segment than normal objects, which are usually smaller and have less textural detail. In the process of segmentation, target objects are easily omitted and misdetected, which is problematic. To alleviate these issues, we propose local aggregation feature pyramid networks (LAFPNs) and pyramid integrated context modules (PICMs) for aerial object segmentation. First, using an LAFPN, while strengthening the deep features, the extent to which low-level features interfere with high-level features is reduced, and numerous dense and small aerial targets are prevented from being mistakenly detected as a whole. Second, the PICM uses global information to guide local features, which enhances the network's comprehensive understanding of an entire image and reduces the missed detection of small aerial objects due to insufficient texture information. We evaluate our network with the MS COCO dataset using three categories: airplanes, birds, and kites. Compared with Mask R-CNN, our network achieves performance improvements of 1.7%, 4.9%, and 7.7% in terms of the AP metrics for the three categories. Without pretraining or any postprocessing, the segmentation performance of our network for aerial objects is superior to that of several recent methods based on classic algorithms.

This paper aims to reexamine the issue of racism in Conrad's Heart of Darkness, especially in the light of Chinua Achebe's critique of the novella as a racist text entrenched with European prejudices of Africa and its people in his 1975 speech at the University of Massachusetts titled "An Image of Africa." While the novella's indictment of imperial exploitation has been noted from an early stage of its critical reception, its racism had hardly been discussed until Chinua Achebe posed it. Achebe offers the canonized status of the text as a modernist classic, "the most commonly prescribed novel in twentieth-century literature courses," as one reason for its obvious manifestations of racism being glossed over. One may add that Conrad's militant denunciation of imperialist enterprises as "a sordid farce," his seemingly radical stance against imperialism, serves as ideological constraints upon his readers, blinding them to its immanent racism. A closer look at the novella's attack on imperialism turns out to be contradictory, for it also shows such liberal-humanist ideas as the civilizing mission, the work ethic, and the superiority of civilized man, all of which served to prop up European imperialism at the end of the nineteenth century. This ideological contradiction also accounts for Conrad's racist attitude, which is betrayed in his portrayal of Africans as obscure, primitive. Euro-American imperialism has frequently justified itself by recourse to racism, but racism has not always been allied with imperialism. Some staunch racists such as Robert Knox and Arthur de Gobineau went against imperialism, and Conrad proves one of such cases whose critique of imperialism is voiced in ways that can be characterized as racist.

Lumped Damage Mechanics (LDM) is a theory proposed in the late eighties, which assumes that structural collapse may be analyzed as a two-phase phenomenon. In the first (pre-localization) stage, energy dissipation is a continuous process and it may be modelled by means of the classic versions of the theory of plasticity or Continuum Damage Mechanics (CDM). The second, post-localization, phase can be modelled assuming that energy dissipation is lumped in zones of zero volume: inelastic hinges, hinge lines or localization surfaces. This paper proposes a new LDM formulation for cracking in concrete structures in tension. It also describes its numerical implementation in conventional finite element programs. The results of three numerical simulations of experimental tests reported in the literature are presented. They correspond to plain and fiber-reinforced concrete specimens. A fourth simulation describes also the experimental results of a new test using the digital image correlation technique. These numerical simulations are also compared with the ones obtained using conventional Cohesive Fracture Mechanics (CFM). It is then shown that LDM conserves the advantages of both, CDM and CFM, while overcoming their drawbacks.

The phenomenon of veneration for Queen Mother of the West [西王母 Chn: Xiwangmu Kr: Seowangmo] is a 'cultural flow' that has garnered great interest not only in China but also in Korea for many years. To properly understand the cultural trend regarding the Queen Mother of the West, it is essential to view the related mythology as it corresponds to East Asian women as well as the transformation of society's view of women. In addition to the outcomes that result from the establishment of a patriarchal society, the relationship between goddesses and gods gradually becomes a relationship of discrimination based upon differences. Accordingly, as women change into objects that are given meaning rather than subjects that give meaning, the de-sacredization of the goddess occurs. This paper focused on the changes in the perception of the Queen Mother of the West from the view of Yin-Yang theory. This approach shows a transition process of transforming wherein she has morphed into an assistant or spouse of a god as part of a trend that deemphasizes the divinity of her as a stand-alone goddess. Yin-Yang theory is the key to understanding culture, history, and art as well as Chinese philosophy. This key can be further applied to the theme of women in mythology. What is particularly noteworthy about the process by which the Queen Mother of the West was defined as a goddess is that she was original described as half-human and half-beast and yet by the time her depictions became fully human and fully woman, she was described instead as an absolute beauty endowed with great artistic talent. In this paper, it will be revealed that the perception of the Queen Mother of the West, as an absolute beauty and artistic talent, is embedded with the male societal desire for an image of the feminine as understood via Yin-Yang theory. Queen Mother of the West as she was depicted in the Classic of Mountains and Seas (山海經 Chn: Shanhaijing Kr: Sanhaegyeong) had a half-human half-beast form that instilled people with fear of disasters and punishments from heaven. However, in the Han Dynasty, her religious significance became that of an object to ward off evil and attain blessings. By the time of the novel, Tales of the Strange (志怪小說 Chn: Zhiguaixiaoshuo Kr: Jigoesoseol), from the Wei, Jin, Southern and Northern Dynasties, she was transformed into a goddess in the image of beautiful woman in charge longevity and immortality. From the perspective of Yin-Yang theory, the changes in the perception of Queen Mother of the West was found to contain the following meaning: as an extension of the establishment of a patriarchal system and subordinate laws, her new form was made to be pleasing to the male gaze and Yin-Yang theory was brought in to support those changes later.

In these days, the technology development of the imaging/optic industry and the digital broadcasting replace the classic CRT with the new display devices that is getting slimmer and larger. Especially, when the general TV signal is applied directly to the wide gamut display using LED or laser, which can display higher chromatic colors that can't be reproduced on CRT, the color distortion occurs and it causes serious problems. Thus, in this paper the gamut mapping is studied, which gets rids of the color distortion and utilizes the wider color gamut than that of the CRT sufficiently. In the gamut mapping the general mapping concept is the increasement of the chroma on the same hue plane but it causes the over chromatic enhancement. So, the vector mapping, which increases the lightness md the chroma at the same time, is proposed to prevent the side effect. In the vector mapping the chromaticity is maintained constantly, hence the image can be seen more natural than that of the chroma mapping. By using the gamut fitting, it is compensated that the tone disappearance or the contour effect that is arose from the geometric properties of the input and the output color gamut. These gamut mapping and gamut fitting can prevent the color distortion and reproduce the natural image on the wide gamut displays.

This is an attempt to analyze original films of ChunHyang Jun that Shin Sang-Ok filmed in North and South Korea, focusing on the character of MongYong. These films were made during political transition periods of North and South Korea. Sung ChunHyang was made during the second republic of South Korea, which was established after the collapse of Rhee SyngMan government; and Love, Love, My Love was made in North Korea during the period of power transfer from Kim Il-Sung to Kim Jong-Un. Considering these political changes, the character of MongYong seems to represent the figure of authority North and South Korean society of the time had in mind. First, MongYong in Sung ChunHyang has a strong image of a lover who repays ChunHyang's devotion and sacrifice with romantic affection. As an authoritative figure, he has the aspect of a democratic leader or mediator. On the other hand, MongYong's image in Love, Love, My Love is a heroic authority figure of the revolutionary class. He is a subversive reformer who shows love for the people and treats them favorably, gaining public desire. This research is expected to inspire more studies on the meanings of hit movies based on classic literature under synchronic terms.
