Purpose: The purpose of this study was to identify the influences of type D personality, burnout and work environment on nurses' intention to stay at the hospitals among nurses. Methods: A cross-sectional descriptive design was used. Participants were 135 nurses working at general hospitals. Data were collected using self-report questionnaires. Data were analyzed using the SPSS/WIN 23.0 program for descriptive statistics, independent t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation, and hierarchical multiple regression. Results: The score of nurses' intention to stay was 4.78. 39.3% of participants were classified as type D personality group. The scores of burnout and work environment were 2.92 and 2.39, respectively. Intention to stay was negatively correlated with burnout and positively correlated with nurse participation in hospital affairs, nursing foundations for quality of care, nurse manager ability, leadership, and support of nurses, staffing and resource adequacy. Burnout and manager ability, leadership, and support for nurses explained 46.0% of variance of nurses' intention to stay in the hospitals. Conclusion: The results of the study indicate that nursing intervention programs for increasing intention to stay for nurses should include strategies for decreasing the burnout and increasing manager ability, leadership, and support for nurses.

Groundwater is an important water resource that can be used along with surface water. In particular, in the case of island regions, research on groundwater level variability is essential for stable groundwater use because the ratio of groundwater use is relatively high. Researches using artificial intelligence models (AIs) for the prediction and analysis of groundwater level variability are continuously increasing. However, there are insufficient studies presenting evaluation criteria to judge the appropriateness of groundwater level prediction. This study comprehensively analyzed the research results that predicted the groundwater level using AIs for various regions around the world over the past 20 years to present the range of allowable groundwater level prediction errors. As a result, the groundwater level prediction error increased as the observed groundwater level variability increased. Therefore, the criteria for evaluating the adequacy of the groundwater level prediction by an AI is presented as follows: less than or equal to the root mean square error or maximum error calculated using the linear regression equations presented in this study, or NSE ≥ 0.849 or R² ≥ 0.880. This allowable prediction error range can be used as a reference for determining the appropriateness of the groundwater level prediction using an AI.

With the development of IT convergence technology and the construction of infrastructure for water leakage detection, the detection technology of damaged pileline's location and size is being spotlighted. The exhaustion of water resource due to the leakage of water supply facilities renders it urgent to detect water leakage effectively. In this paper, we proposed the water leakage detection monitoring simulation using the power spectrum analysis. We measured the reflected wave signal by the proposed water leakage detection monitoring simulation. The rate variability is calculated form the acquired reflected wave signal. And the power spectrum analysis using the Fast Fourier Transform is evaluated the correlation between the water leakage's size and the reflected wave. Ultimately, this paper suggests empirical simulation to verify the adequacy and the validity. Accordingly, the satisfaction and the quality of services will be improved the efficient management by supporting the real-time water leakage detection.

Purpose: This study was conducted to examine how nurse practice environment and organizational justice affected job embeddedness in the Small and Medium Sized Hospital Nurses. Methods: The data were collected from 233 nurses by means of self-reported questionnaires on August 23th to September 8th, 2017. Results: The model explained 49.7% of the total variance in job embeddedness scores. Hierarchical regression analysis showed that hospital nurses that had higher perceived nurse practice environment, higher organizational justice, and were older were more likely to have higher job embeddedness scores. Conclusion: To enhance nurses' job embeddedness, hospital and nurse leaders should improve nurse practice environment, particularly in relation to staffing and resource adequacy and collegial nurse-physician relations. Additionally, the nurse leaders can facilitate nurses' job embeddedness by creating and maintaining an organizational culture of fairness and justice.
