  • This study was carried out to investigate the effects of dandelion leaf, root and whole part extracts on the physicochemical characteristics of pork patties stored at $4^{\circ}C$ for 10 days. Four types of pork patties were evaluated: ice-water-added (T0), dandelion leaf extract (T1), dandelion root extract (T2) and dandelion whole part extract (T3). The pH decreased significantly during storage, but increased after 10 days of storage. The pH was highest in T0 during storage. The L value of T0 increased whereas T1, T2 and T3 did not significantly changed during storage. The a value decreased with a longer storage period, and the a values for T1, T2 and T3 were higher than that of T0 during storage. The b value did not change significantly during storage. The TBARS increased with a longer storage period, and the values for T0, T1, T2 and T3 were 0.87, 0.29, 0.47 and 0.31 mg MA/kg, respectively, after 10 days of storage. The VBN content value of T0 increased, but those of T1, T2 and T3 did not significantly change during storage. The water holding capacity of T0 decreased, but those of T1, T2 and T3 did not significantly change during storage. Cooking loss increased during storage and that of T0 was higher than those of T1, T2 and T3. Hardness and chewiness decreased while springiness and cohesiveness increased during storage.

  • The article seeks to explore Ukrainian media art and its features in a global context. In particular, it performs an in-depth analysis of the stages of its development from video art of the 1990s, media installations of the 2000s, and to various digital and VR technologies today. Due to historical circumstances, the development of media art was quite rapid, as young artists sought to gain new experience in media art. Most often, their experience was broadened through international cooperation and studying abroad. The paper analyzes the presentation of Ukrainian media art outside the country during 1993-2020 and distinguishes the main thematic areas of the artists' work. It examines how artists present and reveal the peculiarities of the Ukrainian worldview, aesthetics, and culture through the problematization of certain aspects and themes in their work. Specifically, among the principal topics which are problematized in the work of media artists are a sensory experience, limited sensory capabilities, gender issues, the Chernobyl tragedy, the development of utopian models of the city, and global communication. The leading themes of Ukrainian artists also include revolution and war. Notably, political and social sentiments determine the unique energy and vitality of contemporary Ukrainian art, create a revolutionary creative environment, and unite media artists in group art projects. It is concluded that by showing, exhibiting, and presenting them outside the country, artists shape the image of Ukrainian art in a global context.

  • The nutritional composition of Korean native black cattle (KNBC) and Hanwoo beef were compared. According to the results, there were no significant differences in moisture, protein, ash, calorie and collagen content, but the fat content of KNBC was significantly higher than that of Hanwoo (p<0.05). The P, Na and Cu content of KNBC were significantly higher than that of Hanwoo (p<0.05). The KNBC and Hanwoo had total mineral amounts of 4,052.34 and 3,214.44 ppm, respectively, with the KNBC being significantly higher than Hanwoo (p<0.05). The vitamin B1 content of KNBC was significantly higher than that of Hanwoo (p<0.05), but there was no significant difference in B2 content between the samples. The total structural amino acid contents was not significantly different between KNBC (12.35%) and Hanwoo (12.58%). The KNBC and Hanwoo had total free amino acid amounts of 752.698 and 661.795 ppm, respectively, with the KNBC being significantly higher than Hanwoo (p<0.05). The stearic acid (10.631%), linoleic acid (2.271%), linolenic acid (0.065%) and tricosanoic acid (0.038%) contents of KNBC were lower than those of Hanwoo (p<0.05). However, their palmitoleic acid (5.292%), oleic acid (48.815%), ${\gamma}-linolenic$ acid (0.094%), eicosenoic acid (0.042%) and docosadienoic acid (0.099%) contents were higher than those of Hanwoo (p<0.05). There was no significant difference between the KNBC and Hanwoo in the saturated fatty acid : unsaturated fatty acid ratio.

  • The Quality of physical therapy school system has conflicts between physical therpist, and reduces the opportunity of seguential education. So this study was investigated in order to made concrete the problems of educational duality, set up the direction of the school system's improvement, as like the four-year system and recognized the necessity. The curriculums of 13 colleges and 5 universities was analyzed. The curriculum analysis was made up the comparison and the analysis by a liberal arts point, a major point, a clinical practice point, total opening subjects, and so on. The analyzing results were as follows. 1. The average rates of a liberal arts vs. a major opening point are 17:83 in college, and are 27:73 in university. 2. It is a serious problem that college are lower than university in a liberal arts. The best method that can solve it is lengthen the number of school years. 3. There is no difference between college and university in a major subject. Rather college has the more subject's numbers than university. 4. There is no difference between college and university in a clinical practice. Above results suggests that there is not different between college and university in a major subject except for a liberal arts point. It is proper that one should be unificate the curriculum according to the sameness between a state examination and a license. Therefore, it is necessary for graduates from college that provides the opportunity of proceeding to a higher school, demands the seguential system of study cultivating and producing a bachelor, and requires the continual education in a clinical field, a bachelor admitting system of continual education, and clinical therapist's qualification. The present physical therapy educational systems should be unificated because of many right reasons. On the other hand, the follw-up study that improving the school system about the four-years and the more physical therapy should be continue from the viewpoint of education.
