  • The purpose of this paper is to illuminate how Suzan-Lori Parks reveals colonized oppression and violence in a black woman's body in Venus. The body of Hottentot Venus is an 'object' of white male spectators' gazes and a dissection from a medical study. The report on her pathologic anatomy gives the audience the illusion that the body of a black woman is inferior to those of others. Not only 'subjective' aesthetics, but also 'objective' medicine makes us confuse 'fact' with 'truth' about black women. By publicly exhibiting her erotic body, Venus is represented as a singular emblem for nineteenth-century colonial discourse on race and sexuality. Her body stands for the powerful signifier of raped Africa. A distinctive feature of black Venus is her raciality. The ownership of her body is only transferred from Mother-Showman to Doctor Baron. She had no right to her ownership. Her body is an object of hatred and curiosity and at the same time a site which is represented by conflicting desires. Parks' eventual goal in Venus is to investigate 'hindsight' of Venus Hottentot, 'the past' and 'the posterior'. As the meaning of original chocolate can be regained, the insulted and damaged body of Venus should also be recovered and resurrected.

  • The purpose of this study is to abstract the image from black dress, which has been favored by many people regardless of the times and examine it throughout the history of drss and thereby clearly define the images that black limplies in dress. Color image is a visual symbol, an image that forms through a combination of visual stimulus created by color, coupled with all the external factors related to it. Black is a one-dimensional color, of which the impact is subjective to its energy, which depends on light reflected on the object, and its texture. Therefore, black projects different images, depending on its surroundings. In general, black has had negative connotations in the Western culture. In dress, however, it has implied other various images different from the general negative ones. By combining general images of black and those exprssed in dress, major images of black were categorized into dignity, elegance, eroticism, asceticism and tragedy. Dignity is a category similar to the sublime. Dress with dignity has sharp contours and is generally made of velvet or silk which can be characterized by their splendor and voluminous-ness, exaggerating the body of a person wearing it. Such costume is mostly found in powerful countries in history such as Burgundy Court in the 15C, Spain in the 16C. Netherlands in the 17C. Elegance evokes grace and beautifulness. It includes elegance, grace, beauty and dandyism as subcategories or silk. Good examples are dandies' black costume and Ladies black and white dressees in the 19C. Eroticism is an image which expresses sexual attractiveness. Costume with eroticism is made of velvet or silk, which project sumptuousness through reflection. Such costumes expose parts of the body or are tightly tailored in order to emphasizes body contours. Asceticism means restraint from physical and mental desires. Costume with asceticism makes a person wearing it look smaller by covering the whole body. Puritan's black dresses and Bourgeoisie's black suit are good examples. Tragedy is anguish. sorrow. Black costume with grievous feelings such as mourning dresses is made of lusterless textile concealing most of the body except for the face.

  • Previously we have reported that black ginseng was produced by nine-time repeated steaming 5-year fresh ginsengs at 95${\circ}$C for 3hr in pottery apparatus and drying at 60${\circ}$C for 12${\sim}$36 hr and had an outstanding anticancer activity. This study was designed to examine the ability of black ginseng to suppress body weight gain appetite, and to investigate the effect of black ginseng on lipid profile in male rats fed normal diets. The extract of black ginseng was administered daily for 3 weeks, and the changes of body weight and food intake were measured. After administering the extracts for 3 weeks, the fat weight and serum lipid levels were also measured. Black ginseng persistently suppressed weigh gain and food intake was also reduced, but not significantly; The weight of both epididymal and abdominal fats was decreased In black ginseng-treated rats. Serum triglyceride level in rats administered with black ginseng was also significantly lowered. Therefore, these results reveal that the repeated administration of black ginseng causes a suppression of body weigh gain by decreasing triglyceride level in blood and body fat deposit.

  • For development of a human body model for electric shock, electroconductive paints with carbon black as a filler material were developed. The characteristics of the volume resistivities of thin films fabricated using the electroconductive paints were investigated as a function of the particle sizes and content of carbon black. With a carbon black particle size over $80\;{\mu}m$, agglomeration of carbon black powders was observed. The volume resistivity of the particles increased as the porosity increased and as the amount of carbon black decreased due to the agglomeration of carbon black powders. With a particle size of $4\;{\mu}m$ and $20\;{\mu}m$, agglomeration of carbon black powders was not observed and their porosities were measured as 0.86% and 1.12% with volume resistivities of $20\;{\Omega}{\cdot}cm$ and $80\;{\Omega}{\cdot}cm$ respectively. A carbon black particle size of less than $20\;{\mu}m$ is considered to be suitable as a type of electric-shock electroconductive paint for a human body model.

  • Eurasian black vulture (Aegypius monachus) belongs to family Accipitridae and is a raptor preying small birds and mammals. It is a wintering bird residing from the mid of November to the late of March in Korea. Although Eurasian black vulture population wintering at Korea is gradually increased, the efficient rescue and treatment for injured Eurasian black vultures are still problematic, due to lack of basic data. Therefore, in this survey, to obtain basic resources for establishing more efficient rescue system, we surveyed the number of Eurasian black vultures wintering at Gangwon province, wintering ecology and injury state of Eurasian black vulture. Survey area was Togyo reservoir at Cheorwon, Seonan basin at Yangoo and Wolsong reservoir at Chuncheon from November 2004 to March 2005. From 12 rescued Eurasian black vultures, physical examination, total plasma protein (TPP) and packed cell volume (PCV) were measured. To survey injury state of Eurasian black vultures wintering at Gangwon province, we surveyed the cause, morbidity and mortality from 103 Eurasian black vultures, based on medical records from animal rescue teams. The number of eurasian black vultures were gradually increased from November, peaked at Feburary, then steeply decreased at March. Eurasian black vultures showed the most vigorous activity around 1 PM within a day. In physical examination, mean body weight was $9.6{\pm}1.22kg$, body length was $1130{\pm}45.4mm$. No statistically significant difference in body weight and length between male and female eurasian black vultures was observed. Mean PCV was $40.2{\pm}2.7%$, while mean TPP was $5.86{\pm}0.8mg/dl$. The most common cause of injury and mortality was intoxication, while that of morbidity was fatigue.

  • This study examines black images as 'the other' in history and aims to analyze images of black female fashion models which have been changed in modern society, particularly in $21^{st}$ century post-modern world. Black images, established historically as illustrated on the paintings in $19^{th}$ century, were disseminated in $20^{th}$ century throughout the world especially by way of TV and movies as several typical images such as 'Coon' the clown as the object of entertainment, 'Buck' wild and resistant black rascal, and 'Mammy' obedient and fat black woman servant. The result of image analysis of black female fashion models, can be summarized as following five images. The first is the image of 'powerful'. Black female models frequently represent healthy image which reflects black people's excellence in sports and also the traditional Image of black skin color as strength. The second is the image of 'sexy'. They are adored as having perfect ideal body shape. They show off their sex appeal with their body. The third image is 'multicultural'. Black models represent cultures besides the western. The fourth is the image of 'fantastic'. In contrast to the real, resonable things, black female models represent wild, fancy, ghost things. The fifth is the image of 'racial discrimination' By arranging them in contrast to whites, a metaphoric image of racial discrimination can be displayed. The result shows that tome of racial images still remain on the other way.
