This paper proposed the validity and necessity of establishing the Jungwon Historical and Cultural Area by reviewing the historical characteristics of the name Jungwon and its temporal and spatial range. We also explored ways to utilize the Jungwon historical and cultural Area under the Special Act on the Maintenance of Historical and Cultural Areas. Jungwon, which means the center of the country, has strategic value as a key area connecting the Korean Peninsula to the north and south through the Geripryeong and Jukryeong. It also includes Chungju, which connects the Namhan and Bukhan Rivers . From the Mahan period, the areas of Cheongju and Jincheon, the Miho Stream basin to the west, and Chungju to the east were closely connected to each other. Afterwards, Baekje, Koguryo, and Silla engaged in a fierce battle to occupy the Jungwon area. Jungwon culture was born through the negotiation and fusion of the cultures of the three kingdoms. In particular, Silla continued to value the Jungwon area, demonstrated by the installation of Seowongyeong in Cheongju and Bukwongyeong in Wonju, centering on the Jungwongyeong. Since we have a historical view with a focus on ancient kingdoms, we have overlooked the full value of the history and culture of Jungwon. We need to recognize the importance of Jungwon area and think about how to utilize it. Therefore, we suggested in this paper that there be more public information services on the cultural heritage of Jungwon, the historical heritage experience, and the education programs for local residents. The development and operation of Jungwon's history, culture, and tourism contents, as well as the various academic research papers should be used to reveal the identity of the Jungwon historical and cultural area.

This study is to clarify the effect of changes of cultural industries, specialized products and regional festival, in "Junwon culture region". According to this study, "Junuon culture region", as border region of Koguryo, Baekje, Silla kingdom, which has not constituted its original culture, must develop its own specialized products based on culture and history of the three kingdoms in modern meaning. In 21st century, cultural industry of "Junuon culture region" must emphasize the role of linking of Koguryo culture which consists of major culture in North Korea. Because regional festival of "Junuon culture region" as place marketing is concentrated in spring and autumn, regional festival must be a package type of interregional network. In 21st century, "Junwon culture region" as border region of Koguryo, Baekje, and Silla, must be the peace place of cultural industry with maximized merit and high accessibility at present time. And with development of knowledge and information society, cultural industry estate must bring up regional network centralizing Cheongju city.ng up regional network centralizing Cheongju city.

This study aims to understand the effects of nursing college students' anxiety about clinical practice and stress from it during the practice on their nursing professionalism during COVID-19 and be used as baseline data to promote this professionalism. The target is 187 juniors and seniors in nursing college located in Chungnam, Chungbuk, and Gyeongbuk with experience in the clinical practice, and the survey was conducted from September to November 2021. The data was analyzed by t-test, ANOVA, Pearson correlation coefficient, and multiple regression using SPSS 22.0. Nursing professionalism was significantly correlated with clinical practice stress(r=-.151, p=.039). In terms of the factors that influenced the nursing professionalism, the coefficient of determination of satisfaction in major was 5.2%(β=-.24, p=.001), and that of stress from the clinical practice was 3.0%(β=-.17, p=.015), which explains a total of 8.2%. Major satisfaction was the most influential factor predicting greater nursing professionalism. The results of this study demonstrate the necessity to increase nursing students' satisfaction in major and reduce their stress from clinical practice in order to improve the nursing professionalism during COVID-19.

This study was conducted on the manufacturing method of high-strength aluminum bolts. We obtained the displacement-load information by tensile test of the Al 6056 raw material and the T6 heat-treated material and calculated the precise flow stress and fracture limit using repetitive finite element analysis for before and after heat treatment. We designed a multi-stage forging process for T6 heat-treated material, and calculated that the accumulated damage value does not exceed fracture limits by finite element method. We produced the prototype forgings without any harmful defects such as cracks and folding occurring. Bolts made of T6 heat treated material show 9.6%higher tensile strength than T6 heat treated material after wire drawing.
