The purpose of this study is to examine then of motion-capture technology system to develop a multimedia library of Fundamental Breath of Korean Dance. With this library, the multimedia aspect of dance and its applicability could revolutionize the field. One of the foremost benefits would be replication of actual movements. Using this system, a user can monitor the precise motions of arms and legs, which define the Fundamental Breath of Korean Dance. Moreover, three-dimensional computer program would allow dancers to examine their movements in various angles and in slow motion as well. For example, the user can view the snapshot or particular movement by zooming in and out to closely examine one's performance. Another example would be changing stage environments or characters to visualize the actual performance. However, in order to express the unique footwork of traditional Korean dace, adequate characters need to be developed for the program. Also, more intricate motions expressing finger movements and facial expressions could improve the system. This multimedia library enables more effective analysis of elementary movements, allowing the user to learn correct postures. Furthemore, it could be utilized as educational tools in various levels of institution to induce people's interest in traditional Korean dance. It would provide an opportunity to study and research the movements without having to actually perform. If these three-dimensional multimedia contents were to materialize, it could replace the outdated two-dimensional video database, creating user-friendly resources, which could be widely used by the general public. Thus, interest in traditional Korean dance could increase drastically in the long run, and the audience-based industry could benefit greatly. Finally, this system would be an excellent instrument to preserve this art-form, which was thought to be instantaneous. The motion capture system has already been widely used by many industries such as in commercials, animations, movies, music videos, computer games and sports, and it hasrecently influenced the field of medicine. Currently, motion capture technology is in an unfamiliar territory with the performing arts due to costs and difficulties in development. However, with time this techology will innovate the traditional Korean dance in the future.
MC / 9 마우스 비만세포주에서 생성되는 interleukin-4 및 tumor necrosis factor-alpha의 피부감작능 대체시험을 위한 활용도 평가에 대한 연구

We have attempted to develop an in vitro assay using MC / 9 murine mast cell line to classify chemicals into contact sensitizers or irritants. MC / 9 murine mast cell line was in vitro sensitized with anti-dinitrophenyl antibody overnight followed by DNP-albumin challenge for 1 hour. Four chemicals judged to be sensitizing (1-chloro-2,4-dinitrobenzene, hexyl cinnamic aldehyde, eugenol, hydroquinone) and 4 non-sensitizing (methyl salicylate, sodium lauryl sulfate, benzalkonium chloride, dimethyl sulfoxide) by the standard in vivo assays were added just prior to anti-dinitrophenyl antibody sensitization. Concentrations of the chemicals in the culture were 2X, 1X, 0.5X, or 0.1X of IC50 determined by MTT assay. No significant modulation of interleukin-4 production from MC / 9 mast cells was observed in the presence of the test chemicals. Whereas, elevation in the level of tumor necrosis factor-alpha (TNFα) productioan was apparent in the sensitizing chemicals, but not in the non-sensitizers compared with vehicle treatment. If threshold value to classify chemicals into sensitizer were set at 125%, the highest TNFα production rate among the non-sensitizing chemicals tested, 1-chloro-2,4-dinitrobenzene, hexyl cinnamic aldehyde, and hydroquinone was positive for enhancement of TNFα production, resulting in classification as sensitizers. In conclusion, being considered a valuable alternative tool for screening chemicals for their sensitizing potential, production of TNFα from MC / 9 mast cell line should be investigated further using more sensitizing or irritant chemicals.

Purpose: Childhood allergies are a serious problem, as they may lead to lifetime chronic disease. Determination of total and specific IgE levels isknown to be a diagnostic tool for allergic sensitization; however, IgE levels are affected by various factors, such as age, sex, ethnicity, and geographicarea. Thus, we evaluated the distribution of total and specific serum IgE levels against seven inhalant allergens in preschool children and examinedtheir association with allergic diseases in Seoul, Korea. Methods: Total/specific serum IgE determination and skin prick tests for seven commonallergens were performed on 509 children aged 3 to 6 years from 16 child care centers in Seoul, Korea. Demographic characteristics were surveyedfrom parents using a modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. A diagnosis of atopic dermatitiswas made by physicians. Results: The geometric mean of total IgE was 80.48±3.80 kU/L in preschool children. IgE levels were higher in boys(boys, 102.34±3.52 kU/L; girls, 62.37±3.93 kU/L; P<0.001) and atopic subjects (atopic, 158.00±3.35 kU/L; non-atopic, 52.75±3.44 kU/L; P<0.001). An increased prevalence of atopy was associated with a high monthly household income (P=0.004) and higher maternal education level (above university-level education; P=0.009), as well as increased total IgE levels (P=0.036). Physician-diagnosed atopic dermatitis was associated with sensitizationto inhalant allergens. Conclusions: Total IgE levels were very high as compared with those in previous reports from other countries. Themost common sensitized allergen was Dermatophagoides farinae, and the positive response rate peaked at age 3 years and was maintained thereafter,particularly in boys. Specific IgE levels for seven inhalant allergens varied with age in preschool children. Although further investigations areneeded with a broad range of ages and various allergens, the distribution of the total and specific serum IgE levels in preschool children might helpto serve as a reference value to diagnose atopy.
