The effects of geographical and climatic factors on annual and monthly pan and Penman evaporation were analyzed. 52 climatological stations were selected and trend analyses were performed. Furthermore, cluster analysis and multiple linear regression analysis were performed to understand the effects of geographical and climatic factors on pan and Penman evaporation. Based on stepwise multiple linear regression analysis, annual pan evaporation is proved to be mainly controlled by urbanization as geographical factor, and annual pan evaporation is also controlled by temperature, relative humidity, wind speed, and solar radiation as climatic factor. Especially wind speed is considered to be most significant climatic factor which affects pan evaporation. Meanwhile, Penman evaporation is not affected by geographical factors but it is affected by climate factors such as temperature, relative humidity, wind speed, and solar radiation except precipitation. Furthermore, the study results show that only proximity to coast affects pan evaporation trend on July; however, geographical and climatic factors do not affect pan evaporation trends in annual basis and monthly basis (January, April, and October). On the other hand, Penman evaporation trends were not affected by geographical factors in annual and monthly basises.

The purpose of this study is to examine the moderating effect of emotional bond in the effect of the congruence of self-image and the team's loyalty to professional baseball spectators, to enhance the effectiveness of emotional bond between the club and the spectator, and to suggest implications for establishing the club's brand marketing strategy. For this purpose, a survey was conducted on 500 professional baseball spectators, and the results of correlation analysis, stepwise regression analysis and hierarchical regression analysis using SPSS 21.0 based on 450 collected data are as follows. First, among the professional baseball spectators and the team's self-image, the realistic self-image factor had a significant effect on the club's loyalty. Second, it was confirmed that the congruence of realistic self-image moderated the effect of congruence of realistic self-image on club loyalty. This result shows that the formation of emotional bond has no influence on the congruence of ideal self-image and is related to the realistic self-image that the club is showing at present. Therefore, it is necessary to establish a marketing strategy that can highlight this effect by considering these points.

In this study, in order to understand the social psychological characteristics of college male students majoring in beauty, PAI tests were conducted on 163 university students located in Gyeonggi-do and Chungnambuk area in 2020. First, when comparing the average scales of men who majored in beauty and men who majored in general, the major male students of beauty showed an overall high clinically recognized type compared to students who majored in beauty, and a negative impression on a valid scale (NIM) considered treatment for physical complaints (SOM), depression (DEP) and drinking problems (ALC) on a clinical scale, and a significant difference was shown on a suicide idea (SUI) scale. Secondly, in order to navigate the PAI scale that significantly predicts beauty major male students, a stepwise regression analysis was performed using 15 significant scales as search factors in comparison between beauty major male and general major male students. As a result, physical complaints (SOM) and depression (DEP) scales were extracted, which became a factor that can predict male students in beauty major. Therefore, it can be understood that the male students in the beauty major have behavior patterns that are more obsessed with and more impulsive to physical problems than the male majors. These results will provide a lot of suggestions for the selection of future male students in beauty major, selection, management, education, consultation materials, and selection of occupations after graduation.

The purpose of the study was to find out the effects of women's gender role attitudes on depression. We also studied self-esteem and family life satisfaction as mediating factors on depression. The data was from the National Welfare Panel Study of 2009 and the analyses were conducted on 3,791 women and 3,467 men aged from 20 to 59. Independent samples t-test and stepwise multiple regression analyses show significant gender differences on depression and gender role attitudes. Women score higher than men in depression and gender role attitudes. Those who have higher traditional gender role attitudes manifest higher score on depression. We also found out that self-esteem and family life satisfaction are the mediating factors for women's depression. As a result, gender role attitudes demonstrate direct and indirect effects on depression through mediation of self-esteem and family life satisfaction. Clinical implications are discussed to consider women's gender role attitudes, their self-esteem and family life satisfaction while consulting with depressed women.

Ground-penetrating radar (GPR) surveys are commonly used to monitor embankments, which is a nondestructive geophysical method. The results of GPR surveys can be complex, depending on the situation, and data processing and interpretation are subject to expert experiences, potentially resulting in false detection. Additionally, this process is time-intensive. Consequently, various studies have been undertaken to detect cavities in GPR survey data using deep learning methods. Deep-learning-based approaches require abundant data for training, but GPR field survey data are often scarce due to cost and other factors constaining field studies. Therefore, in this study, a deep- learning-based model was developed for embankment GPR survey cavity detection using data augmentation strategies. A dataset was constructed by collecting survey data over several years from the same embankment. A you look only once (YOLO) model, commonly used in computer vision for object detection, was employed for this purpose. By comparing and analyzing various strategies, the optimal data augmentation approach was determined. After initial model development, a stepwise process was employed, including box clustering, transfer learning, self-ensemble, and model ensemble techniques, to enhance the final model performance. The model performance was evaluated, with the results demonstrating its effectiveness in detecting cavities in embankment GPR survey data.

The underground disposal facility for spent nuclear fuel demands a specialized design, distinct from conventional practices, to ensure long-term thermal, mechanical, and hydraulic integrity, preventing the release of radioactive isotopes from high-temperature spent nuclear fuel. SKB has established design criteria for such facilities and executed practical design implementations for Forsmark. Moreover, in response to subsurface uncertainty, SKB has proposed an empirical approach involving monitoring and adaptive design modifications, alongside stepwise development. SKB has further introduced a unique support system, categorizing ground types and behaviors and aligning them with corresponding support types to confirm safety through comparative analyses against existing systems. POSIVA has pursued a comparable approach, developing a support system for Onkalo while accounting for distinct geological characteristics compared to Forsmark. This demonstrates the potential for domestic implementation of spent nuclear fuel disposal facility designs and the establishment of a support system adapted to national attributes.
