For the description of the elastic properties of linear objects a convenient parameter is the ratio of the stress to the strain, a parameter called the Young's modulus of the material. Young's modulus can be used to predict the elongation or compression of an object as long as the stress is less than the yield strength of the material. Conventional method for estimating Young's modulus measured the ratio of stress to corresponding strain below the proportional limit of a material using a tensile testing machine. But the method needs precision specimens and expensive equipment. In this paper, we proposed method for estimating Young's modulus using accelerometer. The basic idea comes from that the wave velocity is different as the Young's modulus. To obtain Young's modulus, a group velocity is obtained. It is difficult to measure group velocity. This is because plate medium has a dispersive characteristics which has different wave speed as frequency. In this paper, we used Wigner-Ville distribution to measure group velocity. To verify the proposed method, steel and acryl plate experiments have been performed. Experimental results show that the proposed method is powerful for estimating Young's modulus.

한국 중앙아시아학의 연원

The purpose of this article is to explain how Central Asian studies, or the study of the Silk Road in its broad meaning, existed and developed in Korea long before “The Association for the Central Asian Studies of Korea (1993)” and “The Korean Association for Central Asian Studies (1996)” were founded. The development of Central Asian studies in Korea has three stages. The first is the stage of making connections (1900s-1945). Notable examples in this stage include a visit of the respected Swedish leader of Central Asian studies, Sven Hedin (1865-1952), to Korea and his lecture on the nineteenth of December in 1908 on the topic of the Silk Road for Koreans. This was the first such lecture in Korea. Another example is Kimm Chung-Se (金重世, 1882-1946) the first Korean scholar who studied in Germany, finished the doctoral course at Berlin University, and published an annotated translation of a Central Asian Buddhist script (a list of Buddhist rules [佛敎戒本: Pratimoksa]) in an international academic journal(Asia Major, vol.2, Leipzig 1925). The second is the germination stage (1946-1979): Korean scholars who studied at the University of Tokyo in Japan, including Koh Byong-ik (高柄翊, 1924-2004) who taught classes on the history of east and west cultural exchange at Seoul National and Yonsei Universities, and Jo Jwa-ho (1917-1991) who first used the concept of ‘The Silk Road,’ in his book. In addition, in 1976 a class of Central Asian Art was first opened in Korea at Hongik University which laid the foundation for the development of Central Asian studies. In 1977 an international symposium about the Silk Road was first held in Korea hosted by the National Academy of Sciences in which Higuchi Takayasu from Japan and Joachim Werner from Germany gave presentations. The third is the transition stage (1980-1993): scholars of Central Asian Studies abroad came back to Korea and made their contributions. In 1986 the Central Asia Room was opened at the National Museum of Korea exhibiting items from the Otani Collection, giving an opportunity to popularize the field. In 1991, Silk Road antiquities from the Hermitage Museum in Russia and the Berlin Museum in Germany were first exhibited at the National Museum of Korea as Korean Central Asian studies gradually internationalized. Moreover, in this stage there was a crucial international academic event, the International Silk Road Great Expedition: Xinjiang, Southern Russia, and Maritime Route hosted by Unesco(1990-1991). This gave a precious opportunity for Koreans to meet foreign scholars of Central Asian studies and to view antiquities. Also the participation of Korean experts of Central Asian Studies, including Kwon Young-pil and Kim Ho-dong, resulted in significant achievements and brought about the organization in 1993 of the Association for the Central Asian Studies of Korea as well as the founding of its later form, the Korean Association for Central Asian Studies in 1996.

The purpose of this study is to examine collegian's consciousness for the Olympic Games and to propose the data in establishing desirable policy by collegian's attitude for openning the Pusan Asian Games successively in 2002. The method of systematic stratified cluster random sampling was taken from among the population of 909 collegians in Pusan. The statistic analysis methods adopted here are a frequence analysis, χ2 test, t-test, and One-way ANOVA by way of the SPSS PC' statistic program. The conclusion of this research are as follows : The first, collegian's consciousness for the Olympic Games. 1. Male collegian were found to have a high positive consciousness compared with female's consciousness by gender in the Olympic Game's subordinate factors, world peace and international relationship, sports facilities preparation and expansion, fairplay spirit and sportsmanship cultivation, young people's upbringing, image construction as international city, development planning of local economy, people's physical fitness elevatin. 2. In the Olympic Game's subordinate factors by major, athletic major student's compared with other major students were found to have a high positive consciousness in world peace and internation relationship, sports facilities preparation and expansion, fairplay spirit and sportsmanship cultivation, young people's upbringing, professional play's participation, people's physical fitness elevation. 3. In the Olympic Game's subordinate factors by sport interest. Collegian were found to have a high positive consciousness in the groups taken large interest than not any interest about sports in world peace and international relationship, sport's publication contribution, sports facilities preparation and expansion, fairplay spirit and sportsmanship cultivation, young people's upbringing, road and traffic's preparation, image construction as international city, development planning of local economy, people's physical fitness elevation. The second, collegian's attitudes for the Pusan Olympic Games. 1. Pusan collegians were found to think of the 2002 Pusan Asian Games very positively (89.4%), and willing to participate in various patterns(81.5%), such as indirect participation, professional skill service, and other labor service. 2. Among the top tasks to be solved in preparation for the Asian Games were expanding transportation and communication facilities(25.4%), improving citizens' consciousness (22.7%), and the creation of comfortable urban environments(20.6%). The key items of citizens' consciousness wanting improvement as required from host citizens were disorder(39.0%), and unkindness(29.7%). 3. About half(48.9%) of the collegians believed that the heat of the Pusan Asiad would e somewhat depressed due to the great zeal of the 2002 Korea-Japan World Cup to be held in the same year. 4. The main advantages of the Asiad to the city were found to be the effects of local development(45.4%) and the city's image elevation(28.5%). Most collegians(73.9%)thought that the sports facilities should be open to the public after the Asian Games.

노작(露雀) 홍사용(洪思容) 시(詩)와 희곡(戱曲)에 나타난 메나리적 요소(要素)와 상관성(相關性)

손필영(孫必榮) ( Sohn Pil-young ) 한국어문교육연구회 2019 어문연구(語文硏究) Vol.47 No.4

홍사용의 희곡에서 메나리적 요소를 발견하는 것은 우연한 일이 아니다. 그가 1919년부터 쓴 시조집 청구가곡에서 추구한 운율과 앎과 삶을 일치하려는 조선정신은 <백조>에 발표한 현대시에도 의미와 분리되지 않는 리듬과 이미지로 나타난다. 이러한 메나리 정신은 그의 <토월회> 운영 관여와 공연 활동과 연계되어 나타났다. 특히 극단 <산유화회> 창단과 극 창작 및 연출은 그의 정신을 실천적으로 드러냈다고 할 수 있다. 공연된 「향토심」은 이러한 특징을 담아냈고 희곡 「할미꽃」이나 「제석」도 메나리적 요소로 구성되어 설화적 요소와 리듬과 아이러니적 이미지를 혼용하였다. 원본 없이 줄거리만 전하는 「벙어리굿」도 제목부터메나리적 특징을 담았음을 드러낸다. 그의 메나리의식에서 연유된 조선적리듬과 결합된 정조는 후에 민요시에까지 일관되게 실천되었다. 그가 선택한 자유시와 민요시는 당시 우리문단의 서구적인 경향과는 달리 전통시의 맥락에서 창작되었고 그의 메나리정조로 이루어진 희곡작품은 불행한 시대를 사는 인간에게서 시대나 이념에 함몰되지 않는 조선심의 기품을 볼 수 있게 하였다. It is not a coincidence to find the elements of Menari’s style in the Hong Sa Young’s plays. The Confucian Chosun spirit, the concord of rhythm, knowledge and life, which he pursued in < Cheong Goo Ga Gok >, a traditional three-verse Korean poem that he has written since 1919, reveals the rhythm and image reflected in the modern poetry seen after the < Baek Jo >. This Menari spirit is linked with his participation of < Toweol-hwe > operation and performance activities. In particular, his foundation of < Sanyoohwa-hwe >, along with his writing and directing revealed his spirit practically. < Hyang To Shim > captures these characteristics, while the play < Hal Mi Kkot > or < Je Seok > also consist of menaristic elements and consist of poetical irony, mixed with the use of silent scream, narrative elements and rhythm of tale and ironic images. < Beong Uh Ri Gut >, which contains Menari’s element and conveys only the story-line, reveals its Menari characteristic from the title itself. < Heen Jeot > especially, where the story is based on the ‘Lee Cha Don’s death’ , symbolically shaped his spiritual value, interlocked with the period of the era. His fidelity combined with Chosunistic rhythm, which derived from the Menari spirit, was consistently practiced to his folk song poetry later on. Hong created his free verse poetry and folk song poetry from the context of traditional poetry, contrary to the majority of our literary circles during that period, which contained Western tendency. More notably, he linked folk songs and Chosun spirit to the creation of drama and theatrical activities despite living under the colonial in post mid 1920s. The attitude to find the national spirit and cultivate personality was practiced through his play. The play piece composed of the poetic image of Menari makes it possible to see the grace of Chosunism that does not fall into the times or ideologies of human beings living in the unfortunate times, and further provides an opportunity to find the possibility of connecting the modern drama with the traditional drama. Writing a poem during the Japanese colonial era means treading a path as a Chosun’s poet, which can be seen as realization of self-talent from the tradition like the Eliot once said.

This study focuses on fashion adoption behavior of adolescents. The impact of their clothing involvement factors and socio-demographic factors on their fashion adoption behavior was examined. Three core issues were identified for empirical test: 1) Elements of clothing involvement for adolescents; 2) Fashion adoption behavior of adolescents; 3) Impact of clothing involvement elements on fashion adoption behavior. The Likert Type questionnaires were used to measure clothing involvement and fashion adoption behavior. The data of 472 samples drawn from middle and high school students in Taegu Metropolitan City were analyzed by factor analysis, ANOVA, Scheff□ test, t-test and regression analysis. Main results of the study are as follows. 1.Concept of the clothing involvement is composed of five dimensions: importance, fashion, self-expression, pleasure, and buying risk. 2.Socio-demographic factors do influence fashion adoption behavior. Average monthly pocket money, expenditures on clothes and household income are found to have statistically significant impacts on the adoption behavior. Female students are more fashion-oriented than male students. 3.The clothing involvement elements are found to have significant influences on fashion adoption behavior: fashion, importance and self-expression elements on fashion innovation; fashion, importance and pleasure elements on fashion information search. Key words: adolescents(청소년), fashion adoption behavior(유행채택 행동), clothing involvement(의복관여).
