This paper proposes an algorithm for 3D object detection by processing point cloud data of 3D LiDAR. Unlike 2D LiDAR, 3D LiDAR-based data was too vast and difficult to process in three dimensions. This paper introduces various studies based on 3D LiDAR and describes 3D LiDAR data processing. In this study, we propose a method of processing data of 3D LiDAR using clustering techniques for object detection and design an algorithm that fuses with cameras for clear and accurate 3D object detection. In addition, we study models for clustering 3D LiDAR-based data and study hyperparameter values according to models. When clustering 3D LiDAR-based data, the DBSCAN algorithm showed the most accurate results, and the hyperparameter values of DBSCAN were compared and analyzed. This study will be helpful for object detection research using 3D LiDAR in the future.

This study is a descriptive survey study conducted with the aim of analyzing differences in consumption patterns according to the personality types of the Enneagram and providing basic data that can be used for advertising and branding based on it. 43 people who explained the purpose of the study and agreed to participate were conveniently recruited. The research tools were investigated online with the type of personality of the Enneagram of Joo (2003) and the consumption pattern of Jeon (2013). The data analysis utilizes statistical methods such as descriptive statistics, frequency analysis, and one-way ANOVA in the IBM SPSS Statistics 23 program. For consumption patterns 1, 2, 3, and 6, there were statistically significant differences between personality types 1, 2, 3, 5, 7, and 9 (p<.050). Through this study, it was confirmed that consumption patterns vary depending on the type of personality of the Enneagram. The results of this study are expected to provide basic data in establishing effective strategies for branding and advertising of the design that consumers want.

This study is a descriptive research study to confirm the mediating effect of job engagement on the relationship between the nursing organizational culture and the quality of nursing service perceived by nurses. The research subjects and data were collected from June 1 to June 7, 2022, and 215 nurses working at hospital-level or higher medical institutions recruited through the online community for nurses. As a result of the study, Relation orientated culture(Z=3.88, p<.001) and Task orientated culture(Z=3.16, p=.001) affected the quality of nursing service, and it was found that job engagement fully mediating effect. Hierarchical orientated culture (Z=2.39, p=.017) affected the quality of nursing service, and it was found that job engagement had a partial mediating effect. Therefore, in order to improve the quality of nursing services, it is necessary and to promote work engagement by forming a culture to establish a trust relationship among members based on the order and procedure for safety in nursing sites that require rapid and accurate response in emergency situations and performing tasks efficiently to achieve organizational goals.

This study is a descriptive correlation study to investigate the mediating effect of familiarity and social support in the relationship between grit and academic continuity for Mongolian students. A survey was conducted from May 1 to June 30, 2021 on 124 Mongolian students from universities across the country using Google questionnaires. As a result of the study, grit had a significant effect on the familiarity and social support of Korean culture. The intention to continue school was significantly influenced by grit, familiarity with Korean culture, and social support. Grit directly had a significant effect on academic continuity, and familiarity with Korean culture and social support had a partial mediating effect in the relationship between grit and academic continuity. Based on the results of this study, it is necessary to increase grit and seek counseling and education programs to help using Korean cultural familiarity and social support systems.

The purpose of this study was to identify the influencing factors on aging anxiety by middle-aged men in rural areas during the COVID-19 pandemics. The design of this study was descriptive survey study. The participants were 180 middle-aged men aged 45 to 64 living in G province. Collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression analysis with SPSS statistics 26.0 program. As a result of regression analysis, As a result of regression analysis, influencing factors on aging anxiety were stress(β=.10, p=.004), economic difficulties (β=.16, p=.007), COVID-19 psychological distress(β=.18, p=.003), family care burdens(β=.50, p<.001), and the explanatory power of the variables was 60.5%(F=55.93, p<.001). In the future, interventions are needed to manage aging anxiety and stress in middle-aged men, and support policies are needed to reduce psychological distress and overcome economic difficulties caused by COVID-19.

The purpose of this study was to a descriptive research study to understand the relationship between self-esteem, life stress and health promotion behavior of nursing college students, the influence factors of health promoting behaviors. Participants were 115 nursing students in A city. Data collection was conducted from May 2 to 27, 2022. Data were collected with structured questionnaires and analyzed using t-test, ANOVA, Pearson's correlation analysis, and multiple regression analysis. As a result of there were positive correlations(r=.59, p<.001) between the self-esteem and health promoting behaviors, negative correlation(r=-.45, p<.001) life stress and health promoting behaviors. Factors affecting health promoting behaviors of nursing college students were health state(β=.507, p<.001), life stress (β=.249, p=.002) and smoking(β=.156, p=.028), which explained 57.0% of the variance.

This study started with the awareness that the review of the historical origins of Korean broadcasting will be of great significance in exploring the future of Korean broadcasting, and examined the various "origins" of Korean broadcasting - colonial, Cold War, totalitarian, neoliberal. Based on the theoretical background of "media archaeology", the historical 'origin' of Korean broadcasting was applied to track the origin of Hallyu(the Korean Wave) in the 21st century by comprehensively examining the political and economic motives of the time, the state's situational awareness of problems, major broadcasting policies and broadcasting realities. As a result of the study, it came to the tentative conclusion that the historical origin of the Hallyu, which began to be formed in the 1980s, originated from the three origins of Korean broadcasting and the "synthetic mixture" in the subsequent development process.

This study attempted to provide basic data for educational programs to improve career preparation behaviors by identifying the effects of nursing students' self-esteem and empathy on career preparation behaviors. Nursing Students and the 150 people who underwent descriptive research targets, data collection period was done by November 30, 2019 from IRB approval. The data were analyzed correlations between variables were analyzed using Pearson's correlation coefficient, and stepwise multiple regression analysis was used to determine the factors that affect the clinical performance of the Nursing Students (SPSS 23 version). As a result of the study, empathy ability was positively correlated with gender (r=.179, p=.029), self-esteem was negatively correlated with academic performance (r=-.231, p=.005), career preparation behavior showed a positive correlation with the number of practice hospitals(r=.178, p=.030). As the empathy ability of nursing students improved (β=.19, p=.020), career preparation behavior increased. Through this, the study is meaningful in that it suggested the need and direction to maintain a positive attitude toward career preparation behaviors of nursing students. suggest.
