This study attempted to determine the effect of job stress, job involvement, and goal orientation on work-life balance for shift nurses. The subjects of the study were 128 shift nurses working at a hospital in city C of province G. Date were conducted from April 01 to April 15, 2024 using a Google questionnaire. The collected data were analyzed by correlation and multiple regression analysis. The total explanatory power was 28.0%. The results of this study showed significant differences in job stress(β=.405, p<.001), goal orientation(β=-265, p=.002), and job involvement(β=.174, p=.037) as factors affecting the work-life balance of shift nurses. Therefore, it is expected to have a positive impact on patient health by contributing to the improvement of the quality of nursing services by forming an organizational culture that avoids excessive goal setting and allows employees to concentrate on their work with appropriate stress management. This suggests that nurses are not only individuals but also professional medical practitioners, and that maintaining a healthy work-life balance is crucial for the country's human resources, which requires institutional support at the government level.

This study aims to investigate how the social capital of middle school students is influenced by their grades, attitudes, and school interests, which are defined as school adjustment flexibility, and how they affect the social capital of middle school students. This study aims to provide a basis for policy discussions on how to shape the social capital of adolescents. The results of the analysis show that school adjustment flexibility has an impact on each factor of social capital. Trust is positively related to school attitudes, and norms are positively related to school compliance and school interest. Network has a positive effect on school attitude and a negative effect on school enjoyment. These results suggest that the higher the ability to follow the rules, the higher the norms of social capital, which suggests that social norms internalized at the individual level also affect group norms, which are the standards of behavior or rituals that members of a group follow when they want to behave as expected of them. We were able to find out that the normative domain of social capital is expanded by increasing the interest in school life of elementary and middle school students, and we confirmed that school class attitude is a major influencing factor in developing the network of social capital. Therefore, in order to increase the social capital capacity of elementary and middle school students, it is necessary to devise a plan to form various networks through multifaceted efforts to increase interest in school life and changes in school class attitude.

Through the pandemic, the topography of dining culture is rapidly changing due to the advancement of the food delivery market. Competition in the domestic market is intensifying as Coupang Eats recently surpassed Yogiyo and jumped to second place, and Baedal Minjok(Baemin), the industry's No. 1 company, is also preparing to introduce a subscription system. While the growth of the delivery market is slowing, the use of takeout and pick-up services is increasing due to rising delivery costs and food prices. From Generation Z's perspective, the main factors influencing the active use of app services were identified through prior research as usability and convenience, cost sensitivity, and hedonic motivation. While, they are leading the trend of minimizing spending through 'stepping stone consumption' and delivery pot process instead of choosing a subscription system. Accordingly, we aim to provide customers with a better experience and help strengthen competitiveness by proposing ways to improve and revitalize new delivery apps that reflect the characteristics of Gen.Z. As a result of the expert Delphi survey, we will receive impact evaluation scores in the following order: direct view of accumulated discounts, addition of family benefits, coupon reinforcement, SNS promotion, pick-up walk, in-store promotion, and discount rate display, and review their application to practice. It presents academic and policy implications regarding the food tech market.

Background and Objectives: Lipid lowering therapy is essential to reduce the risk of major cardiovascular events; however, limited evidence exists regarding the use of statin with ezetimibe as primary prevention strategy for middle-aged adults. We aimed to investigate the impact of single pill combination therapy on clinical outcomes in relatively healthy middle-aged patients when compared with statin monotherapy. Methods: Using the Korean National Health Insurance Service database, a propensity score match analysis was performed for baseline characteristics of 92,156 patients categorized into combination therapy (n=46,078) and statin monotherapy (n=46,078) groups. Primary outcome was composite outcomes, including death, coronary artery disease, and ischemic stroke. And secondary outcome was all-cause death. The mean follow-up duration was 2.9±0.3 years. Results: The 3-year composite outcomes of all-cause death, coronary artery disease, and ischemic stroke demonstrated no significant difference between the 2 groups (10.3% vs. 10.1%; hazard ratio [HR], 1.022; 95% confidence interval [CI], 0.980-1.064; p=0.309). Meanwhile, the 3-year all-cause death rate was lower in the combination therapy group than in the statin monotherapy group (0.2% vs. 0.4%; p<0.001), with a significant HR of 0.595 (95% CI, 0.460-0.769; p<0.001). Single pill combination therapy exhibited consistently lower mortality rates across various subgroups. Conclusions: Compared to the statin monotherapy, the combination therapy for primary prevention showed no difference in composite outcomes but may reduce mortality risk in relatively healthy middle-aged patients. However, since the study was observational, further randomized clinical trials are needed to confirm these findings.

Recently, earthquakes occurring in Korea have frequently caused damage to buildings and structures. However, since it is impossible to predict when an earthquake will occur, it is challenging to determine the characteristics of the vibrations without pre-installed automated measuring devices. Fortunately, automated measuring devices have been installed at six blasting sites, allowing for the comparison of the characteristics of seismic and blasting vibrations. On June 12, 2024 (Wednesday) at 8:26 AM, a magnitude 4.8 earthquake occurred 4 km south-southwest of Buan-gun, Jeollabuk-do. This study compares the characteristics of seismic vibrations from this earthquake with the measured values of seismic and blasting vibrations at domestic blasting sites. Additionally, we examined the causes and scales of damage from the earthquake, and analyzed the characteristic values obtained from automated measuring devices installed in various regions from the epicenter to determine the degree of attenuation. This study aims to provide a basis for comparing the impact of vibrations from blasting on protected objects and to help preemptively address complaints that may arise from such vibrations in the future.

Potential economic impact of a hypothetical severe accident at a nuclear power plant(Uljin units 3/4) was estimated by applying the Delphi method, which is based on the expert judgements and opinions, in the process of quantifying uncertain factors. For the purpose of this study, it is assumed that the radioactive plume directs the inland direction. Since the economic risk can be divided into direct costs and indirect effects and more uncertainties are involved in the latter, the direct costs were estimated first and the indirect effects were then estimated by applying a weighting factor to the direct cost. The Delphi method however subjects to risk of distortion or discrimination of variables because of the human behavior pattern. A mathematical approach based on the Bayesian inferences was employed for data processing to improve the Delphi results. For this task, a model for data processing was developed. One-dimensional Monte Carlo Analysis was applied to get a distribution of values of the weighting factor. The mean and median values of the weighting factor for the indirect effects appeared to be 2.59 and 2.08, respectively. These values are higher than the value suggested by OECD/NEA, 1.25. Some factors such as small territory and public attitude sensitive to radiation could affect the judgement of panel. Then the parameters of the model for estimating the direct costs were classified as U- and V-types, and two-dimensional Monte Carlo analysis was applied to quantify the overall economic risk. The resulting median of the overall economic risk was about 3.9% of the gross domestic products(GDP) of Korea in 2006. When the cost of electricity loss, the highest direct cost, was not taken into account, the overall economic risk was reduced to 2.2% of GDP. This assessment can be used as a reference for justifying the radiological emergency planning and preparedness.

The purpose of this study is to validate learning progressions for Earth's motion and solar system from two different perspectives of validity. One is construct validity, that is whether a hypothetical pathway derived from our study of LPs is supported by empirical evidence of children's substantive development. The other is consequential validity, which refers to the impact of LP-based adaptive instruction on children's improved learning outcomes. For this purpose, 373 fifth-grade students and 17 teachers from six elementary schools in Seoul, Kangwon province, and Gwangju participated. We designed LP-based adaptive instruction modules delving into the unit of 'Solar system and stars.' We also employed 13 ordered multiple-choice items and analyzed the transitions of children's achievement levels based on the results of pre-test and post-test. For testing construct validity, 64 % of children in the experimental group showed improvement according to the hypothetical pathways. Rasch analysis also supports this results. For testing consequential validity, the analysis of covariance between experimental and control groups revealed that the improvement of experimental group is significantly higher than the control group (F=30.819, p=0.000), and positive transitions of children's achievement level in the experimental group are more dominant than in the control group. In addition, the findings of applying Rasch model reveal that the improvement of students' ability in the experimental group is significantly higher than that of the control group (F=11.632, p=0.001).
