The purpose of this study is to indicate the direction of the future university classes in the post-COVID era, comparing and analyzing lecture evaluation of pre and post COVID-19. To this end, 4 yeard data were used from 2018 to 2019 for pre COVID-19 and form 2020 to 2021 data for post COVID-19. The results were as follows. In the case of liberal arts, "assignments" was the word with the highest frequency and degree centrality(DC) regardless of pre and post-COVID-19 In the major, "understanding" appeared as the most important word. The result of the ego network analysis indicated that "video lecture" and "non-face-to-face classes" were difficult and "interaction" between the professor and the students was important. As a results, it is important to reduce the weight of assignments and increase interaction with students in liberal arts classes. In the case of majors, it is necessary to operate face-to-face classes rather than non-face-to-face classes, and to organize the contents of videos without difficulty.

The purpose of this research is a seismic capacity evaluation and strengthening of existing railway station buildings, which were constructed before the seismic design code activated. The seismic capacity of 2nd story RC station building is evaluated by using nonlinear time-history analysis. Analysis results are checked by story drift ratio and story shear, which are described in design code. As a result, the story shears are exceeding the base shear of the design code, the appropriate seismic strengthening methods are needed. To improve the seismic capacity, metallic dampers are used. Evaluation parameters are metallic damper shape and damper installation methods. Dampers are installed in four places in X and Y directions of station buildings. By reviewing of time-history analysis results, the metallic damper, which is installed inverted K-brace type, shows a better seismic performance than other damper shape and installation methods.

In this study, the problems were analyzed that derived a different position evaluation results depending on the unit grid size that are applied to the terrain slope analysis conducted to assess the its position and environmental impacts in the prior environment reviewing process of golf course construction projects. For this purpose, the unit grid size were analyzed that can precisely reflect a actual terrain by analyzing the change of a slope percentage according to the change of unit grid size about 12 golf courses is currently in progress of construction work through the environmental consultation or ongoing consultation. And the consultation availability of environmental assessment was reverified by applying the unit grid size derived through this study about a study golf course. In the result of study, the bigger grid size for slope analysis is set, the greatly gradient is changed and the slope ratio of the higher elevation was lowly evaluated in comparison with actual terrain. The analytical result that most closely match the actual terrain was extracted in the case applied $5m{\times}5m$ of the unit grid sizes setting in this study. So, we proposed this study results to the ministry of environment and could be amended the unit grid size of $5m{\times}5m$ as standard for the analysis of slope. Also, if new grid size for site evaluation is applied to the study sites, 4 sites exceed the standard suggested the existing regulations and they are not proper as golf course site in flank of environment.

The purpose of this study is to analyze University Woman Students' recognition of their physical bodies and the effects that their recognition has on their image and satisfaction of their physical bodies. The result of study is as follows. 1) According to the result of the analysis of the difference between University Woman Students students' practical physical sizes and ideal sizes, it was showed that their heights and burst should be larger than their practical physical sizes but their waist, hip, and weight should be reduced.2) According to the result of the analysis of the factors for the evaluation of University Woman Students students' behavioral body images, Factor I was 'Management of Appearance', factor II was 'Management of Weight' and Factor III was 'Satisfaction of Appearance'. Considering the result of correlation of factors of the body images, it was showed that the more interest they had on their appearances, the more management they had on their weights. 3) They had comparatively positive recognition on their physical bodies. However, regarding their degrees of the satisfactions on their physical parts, they showed somewhat dissatisfaction on all the items of their physical parts. 4) According to the result of the analysis of the correlation between their recognition of the physical types and their satisfaction of them, it was showed that they had more satisfactions when their heights were higher and their weights were lighter. In addition, it was showed that they had more satisfaction when they had larger busts and regarding their waists, hips, upper arms, lower arms, wrists, thighs, and calf measurements, they had more satisfactions when they had thinner ones and regarding their shoulders' measurements, it was showed that they had more satisfactions when they had narrower shoulders' measurements.

Objective : This study aims to review the current status and problems of Korean Medicine and attempts to come up with the means to present a comprehensive and effective set of statistical data. Methods : We have analyzed the current statistics and tried to show how to establish an effective system to gather and organize statistics related to Korean Medicine, including national surveys by the Ministry of Health and Welfare or other relevant insititutions. Results : The existing statistics in Korean Medicine were established not as a result of national demand based on comprehensive analysis but due to the demand of the government ministries such as the Ministry of Health and Welfare or other relevant institutions. Thus, the statistics have been revealed to possess limitations such as a lack of systemization and consistency. In addition, the statistics analyze only the current industrial status of Korean Medicine, and as a result the information in unable to show systematic data for innovation, which is indispensable for the advancement and development of the Korean Medicine industry. Conclusion : To improve the statistical data in Korean Medicine, the statistics need to get over not only the level of management or regulation in Korean Medicine, but also the production of fragmentary statistics. It has to ultimately reflect the innovative activities in Korean Medicine nationally, and show what we need to advance and develop the industry.

In this paper, a novel method for the classification of term and preterm birth is proposed based on time-frequency analysis of electrohysterogram (EHG) using multivariate empirical mode decomposition (MEMD). EHG is a promising study for preterm birth prediction, because it is low-cost and accurate compared to other preterm birth prediction methods, such as tocodynamometry (TOCO). Previous studies on preterm birth prediction applied prefilterings based on Fourier analysis of an EHG, followed by feature extraction and classification, even though Fourier analysis is suboptimal to biomedical signals, such as EHG, because of its nonlinearity and nonstationarity. Therefore, the proposed method applies prefiltering based on MEMD instead of Fourier-based prefilters before extracting the sample entropy feature and classifying the term and preterm birth groups. For the evaluation, the Physionet term-preterm EHG database was used where the proposed method and Fourier prefiltering-based method were adopted for comparative study. The result showed that the area under curve (AUC) of the receiver operating characteristic (ROC) was increased by 0.0351 when MEMD was used instead of the Fourier-based prefilter.

Researches on librarians' job satisfaction in Korea have been conducted for nearly 40 years. However, it is difficult to find the criteria that specifically evaluate librarians' job satisfaction, and most of the studies have used evaluation criteria developed oversees a long time ago. For these reasons, it is necessary to investigate how librarians' job satisfaction levels have been measured. A total of 68 theses and dissertations were reviewed by dividing period into 10 years backwards from 2016. The chronological changes and trends of evaluation factors were examined and differences were sought among types of libraries. As a result, it was confirmed that there were various changes in the evaluation factors. A standard indicator consisting of 12 evaluation factors and 39 items was proposed by applying three principles that the criteria should reflect factors, questions, and current status.
