The purpose of this study is to discuss the improvement plan of book curation service by examining the current status of book curation, necessity and effectiveness of book curation, targeting librarian teachers. A questionnaire survey was conducted targeting 51 librarians in the Gyeonggi region. The main results are as follows. First, 86.3% of respondents had experience in book curation operation. Second, the most important reason for book curation service was to introduce resources of various subjects to students. Third, the subject of curation were selected by book event and social issues. Fourth, there were many cases where librarians performed services without receiving training on book curation. Lastly, although the recognition that book curation services are necessary is high, they are experiencing operational difficulties due to lack of space and budget. Based on the results, Based on the results, we suggested that this study has academic contributions as data that reports the reality of book curation, and that in order to actively match library resources with users without disappearing, professional education and curriculum of librarians should be able to eliminate common problems in previous studies.

Photoelectrochemical (PEC) water splitting is a vital source of clean and sustainable hydrogen energy. Moreover, the large-scale H₂ production is currently necessary, while long-term stability and high PEC activity still remain important issues. In this study, a GaN-based photoelectrode was modified by an additional NH₃ treatment (900℃ for 10 min) and its PEC behavior was monitored. The bare GaN exhibited a highly crystalline wurtzite structure with the (002) plane and the optical bandgap was approximately 3.2 eV. In comparison, the NH₃-treated GaN film exhibited slightly reduced crystallinity and a small improvement in light absorption, resulting from the lattice stress or cracks induced by the excessive N supply. The minor surface nanotexturing created more surface area, providing electroactive reacting sites. From the surface XPS analysis, the formation of an N-Ga-O phase on the surface region of the GaN film was confirmed, which suppressed the charge recombination process and the positive shift of E_FB. Therefore, these effects boosted the PEC activity of the NH₃-treated GaN film, with J values of approximately 0.35 and 0.78 mA·cm^-2 at 0.0 and 1.23 V_RHE, respectively, and an onset potential (V_on) of -0.24 V_RHE. In addition, there was an approximate 50% improvement in the J value within the highly applied potential region with a positive shift of V_on. This result could be explained by the increased nanotexturing on the surface structure, the newly formed defect/trap states correlated to the positive V_on shift, and the formation of a GaO_xN_1-x phase, which partially blocked the charge recombination reaction.

This study attempted to identify the relationship between nursing students' adjustment to college life, stress, and major satisfaction, and to identify the factors that affect career decision-making self-efficacy. The study included 298 nursing students from two universities in the region, and data collection was conducted from April 24 to May 9, 2023. Results, It showed a significant negative correlation between college adjustment and stress, and it was found that there was a significant positive correlation between major satisfaction and career decision-making self-efficacy. Major satisfaction was the predictor variable that had the greatest impact on career decision-making self-efficacy, and the explanatory power was found to be 44.8%. This shows that nursing students with high self-efficacy are satisfied with their majors and adapt well to university life if they choose nursing studies. Therefore, there is a need to develop various career exploration and career education programs to enhance career decision-making self-efficacy.

Accidents at construction sites have a very high rate of fatalities due to the nature of being prone to severe injury patients. In order to reduce the mortality rate of severely injury patients, quick response is required, and some systems that detect accidents using AI technology and cameras have been devised to respond quickly to accidents. However, since existing accident detection systems use only a single camera, there are blind spots, Thus, they cannot detect all accidents at a construction site. Therefore, in this paper, we present the system that minimizes the detection blind spot by using multiple cameras. Our implemented system extracts feature points from the images of multiple cameras with the YOLO-pose library, and inputs the extracted feature points to a Long Short Term Memory-based recurrent neural network in order to detect accidents. In our experimental result, we confirme that the proposed system shows high accuracy while minimizing detection blind spots by using multiple cameras.

Scaling is one of the most basic dental gum treatments and involves removing tartar that has hardened on teeth. However, inexperienced and unprofessional removal of tartar may damage the gums, resulting in excessive bleeding or damage to the teeth. For this reason, scaling must be done delicately according to the gum structure of various people, and sufficient practice must be provided. Related departments at the university are conducting scaling exercises. However, from the perspective of students who have not had sufficient practice, selecting subjects and conducting practice is not easy, and practice subjects may also avoid participating in practice due to discomfort and anxiety. Accordingly, in this study, we designed and implemented a virtual reality practice system using VR to create a virtual patient rather than an actual subject and implement various gum shapes step by step to enable repetitive practice and various scaling experiences.

Water is an indispensable material for life and health, an essential ingredient for maintaining blood volume, and plays an important role in nutrient supply and waste excretion in the body. Water is also involved in hormone secretion, and when the body dehydration, the main organs cannot function and secrete stress hormones. Therefore, we investigated the changes in salivary cortisol hormone after water intake in 32 healthy adults. They were divided into two groups: The control group (N=16), which consumed water ad libitum, and the experimental group (N=16), which consumed 2L of water per day. Of blood biochemical parameters, a significant decrease in the concentration salivary cortisol hormone decreased in the experimental group. (p < 0.05). In conclusion, a steady and sufficient water intake may contribute to alleviate stress by decreasing cortisol hormone. As a result, constant intake of water appears to reduce the secretion of stress hormones by leading organs functioning properly, further improving immune function.

The purpose of this study is to examine the association between regular exercise habit, self-rated health status, health practice index, and health promotion lifestyle profile among 241 college male students from Gyeonggi-do. Subjects were divided into two groups: students majoring in physical education(PE) and students who are not majoring in PE. The average BMI were $22.77{\pm}2.74$ among PE majors and $21.57{\pm}4.30$ among the other group. PE majors showed higher results in all of physiological, subjective and social health conditions. Both groups showed low scores in health practice index, which were $2.86{\pm}1.10$ among PE majors and $2.97{\pm}1.46$ among non-PE majors, showing no difference in statistical significance. Index for health promoting lifestyle practices were somewhat higher among PE majors; however, there were no statistical significance with the results of $123.38{\pm}19.93$ among PE majors and $119.98{\pm}22.04$ among non-PE majors. The analysis on the index for health promoting lifestyle practices in sub-categories showed that PE majors showed significantly higher scores compared with non-PE majors in physical activities area and vice versa in nutrition area.
