The purpose of this study was investigate the influence between class satisfaction and two types of students majoring in culinary arts in university: major perception type and employment preparation type, The two types of students were subdivided into two types respectively. The date from the results of this study will be shared for teaching and training among faculty and university that offer culinary arts major programs. The result shows that there in a statistically significant positive influence between major perception type and class satisfaction (p<0.001) and between job preparation type and class satisfaction (p<0.014). When comparing the degree of influence, the job preparation type that focuses on spec showed the highest influence (p<0.001, 0.536) in class satisfaction, Next, the perception major that their as a vocational showed the second highest influence (p<0.001, 0.241) in class satisfaction. On the other hand, there in no significant influence between the perception major as an aptitude and class satisfaction (p<0.306, 0.059) and the job preparation that focuses on field experience and class satisfaction (p<0.055. 0.121). In conclusion, this study suggests that universities with culinary arts major need to strengthen vocational training course that help students develop their qualification when setting up curriculum and student guidance directions. In addition, extracurricular programs need to be offered in order to help students learn second language and earn certificates for the future employment through regular and extracurricular courses.

This study, in the context of COVID-19, which started suddenly, the study was conducted between freshman in 2020, who entered the university and took online classes while attending school, and freshman in 2022 who entered the university after experiencing 2 years or more in the Corona 19 environment. This result to provide information for after COVID-19 continuing online classes, student guidance, and educational planning. To analyze the data, SPSS 27.0 program was used, and frequency analysis, mean and standard deviation, correlation, t-test, and regression analysis were performed according to the verification. A comparative analysis was conducted on online classes and college life. As a result, were difference between both, the COVID-19 test and infection rate showed a much higher test and infection rate than in 2020. But, in terms of gender, both groups of freshmen in 2020 and 2022 did not show any statistical significance, also, there were no differences could be found according to gender even over time in the corona pandemic environment. However, in the effect between COVID-19 and the perception of online classes, it was found that the 2020 freshman group had an effect on each other, but the 2022 freshman group did not show any statistical significance.

Ultrasonic Nanocrystal Surface Modification (UNSM) is a peening technology that generates elastic-plastic deformation on the material surface to which a static load of a air compressor and a dynamic load of ultrasonic vibration energy are applied by striking the material surface with a strike pin. In the UNSM-treated material, the structure of the surface layer is modified into a nano-crystal structure and compressive residual stress occurs. When UNSM is applied to welds in a reactor coolant system where PWSCC can occur, it has the effect of relieving tensile residual stress in the weld and thus suppressing crack initiation and propagation. In order to quantitatively evaluate the compressive residual stress generated by UNSM, many finite element studies have been conducted. In existing studies, single-path UNSM or UNSM in a limited area has been simulated due to excessive computing time and analysis convergence problems. However, it is difficult to accurately calculate the compressive residual stress generated by the actual UNSM under these limited conditions. Therefore, in this study, a minimum finite element peening analysis area that can reliably calculate the compressive residual stress is proposed. To confirm the validity of the proposed analysis area, the compressive residual stress obtained from the experiment are compared with finite element analysis results.

The purposes of this paper are to prospect the future of green-tourism in Gyeongbuk since 2002. For rural area and farmers the advent of green-tourism brought great change and opportunities, transforming the area from a traditional rural society to one focusing on environmental agriculture and tourism. First of all, citizens are not likely to bear the large burden of sacrificing their time for more income much longer. Instead, they like to enjoy their life at the expense of wage. So, the five day work system will certainly be a good chance to develop green-tourism. The entrance of green-tourism is a really good opportunity for the rural society. The demand of domestic tourism will completely change our traditional tourism pattern in Korea from non-lasting to lasting tourism, from person to family, from seeing to experiencing, and from culture type tourism to an agricultural pattern. Citizens especially will change their lifestyle to a green lifestyle, so the demand of tourism which is closely linked with agriculture and environment will increase in the near future. There are many tasks and limits to solve green-tourism. We easily can notice the absence of distinction, commercialization, strategic public information and marketing strategy. The government also needs to carry out a lot of tasks such as establishment of laws, institutional structure, and continuous development of educational programs for the farmers.
