  • As there have been many cases where successful regional festivals acts as the promotion of regional brand images and as the driving force of regional economic development, changes in awareness that significantly accepts external promotion effects and the commercial value of regional festivals are greatly expanding. When seen from this perspective, the regional festival, which has Tojeong Lee Ji-Ham, a scholar in the Joseon Dynasty period in the 16th century and Geolincheong as subject matter, is expected to contribute greatly to the establishment of Chungnam Asan region's identity and to the vitalization of the regional economy. He is one of the all-time eccentrics and at the same time he is an intellectual who practiced innovative spirit of the times and a sense of economy for the relief and self-support of common people and the balanced development of the nation during his life. In this sense, the regional festival that is based on Lee Ji-Ham's Geolincheong has meaning and values as a cultural content from and device, which realizes and continues the spirit of the times and the thoughts that he pursued, in the modern context in time and space.

  • The purpose of this study was to determine the muscle activities of the erector spinae (ES), gluteus maximus (Gmax), gluteus medius (Gmed), and the hamstring (HAM) and the ratios of Gmax/ES, Gmax/HAM, and Gmed/HAM during the prone heel squeeze (PHS) with different knee flexion angles ($45^{\circ}$, $90^{\circ}$, and $135^{\circ}$). Fifteen young and healthy subjects (8 men, 7 women) were recruited for the study. Surface electromyography signals were collected on ES, Gmax, Gmed, and HAM during PHS. A separate one-way analysis of variance with repeated measures was used to determine the significance of the muscle activities of ES, Gmax, Gmed, and HAM and the ratios of Gmax/ES, Gmax/HAM, and Gmed/HAM with different knee flexion angles during PHS. There was a significant increase in the Gmax activity at the knee flexion of $90^{\circ}$ in comparison with that of the $45^{\circ}$ (p=.016). There were significant increases in the Gmed activity at the knee flexion of $90^{\circ}$ (p=.008) and $135^{\circ}$ (p=.006) in comparison with that of the $45^{\circ}$. There were significant decreases in the HAM activity at the knee flexion of $90^{\circ}$ (p=.009) and $135^{\circ}$ (p=.004) in comparison with that of the $45^{\circ}$. There were significant increases in the Gmax/HAM muscle activity ratio at the knee flexion of $90^{\circ}$ (p=.007) and $135^{\circ}$ (p=.012) in comparison with that of the $45^{\circ}$. There were significant increase in the Gmed/HAM muscle activity ratio at the knee flexion of $135^{\circ}$ in comparison with that of the $45^{\circ}$ (p=.008). The knee flexion of $90^{\circ}$ during PHS can induce decreasing activity of HAM and increasing activity of Gmax, and the knee flexion of $135^{\circ}$ during PHS can induce decreasing activity of HAM and increasing activity of Gmed. Hence, PHS with different knee flexion positions could be considered for the different target muscle.
