Purpose: This study aimed to provide basic data for the development of education programs which improve the nurses' infection control performance by investigating the knowledge, performance, and educational needs of infection control among nurses in long-term care hospitals, and analyzing the relationship between these parameters. Methods: This was a descriptive study. A self-reported questionnaire was provided to 153 nurses in 210 long-term care hospitals on Jeju Island. Their knowledge, performance, and educational needs of infection control, data were analyzed using SAS Window(ver. 9.4), t-test, Wilcoxon rank-sum test, one-way ANOVA, Scheffe test, and Pearson's correlation coefficient. Results: Both knowledge (r=0.16, p=.042) and performance (r=0.52, p<.001) of infection control had positive correlations with the educational needs of the infection control. Conclusion: The higher the knowledge of infection control was, the higher the educational needs of the nurses were. However, knowledge of infection control did not correlate with performance of infection control. Therefore to increase the knowledge and performance of infection control, infection control education programs should suit the educational needs and the actual conditions of long-term care hospitals.

A correlation analysis was performed to investigate differences in the response of surface water and groundwater to drought using the Standardized Precipitation Index (SPI). Water level data of 20 agricultural reservoirs, 4 dams, 2 rivers, and 8 groundwater observation wells were used for the analysis. SPI was calculated using precipitation data measured at a nearby meteorological station. The water storage of reservoirs and dams decreased significantly as they responded sensitively to the drought from 2014 to 2016, showing high correlation with SPI of the relatively long accumulation period (AP). The responses of rivers varied greatly depending on the presence of an upstream dam. The water level in rivers connected to an upstream dam was predominantly influenced by the dam discharge, resulting in very weak correlation with SPI. On the contrary, the rivers without dam exhibited a sharp water level rise in response to precipitation, showing higher correlation with SPI of a short-term AP. Unlike dams and reservoirs, the responses of groundwater levels to precipitation were very short-lived, and they did not show high correlation with SPI during the long-term drought. In drought years, the rise of groundwater level in the rainy season was small, and the lowered water level in the dry season did not proceed any further and was maintained at almost the same as that of other normal years. Conclusively, it is confirmed that groundwater is likely to persist longer than surface water even in the long-term drought years.

This study was conducted to determine the influence of satisfaction, self-esteem, and depression on adjustment of elderly patients in long-term care hospitals. The subjects were 116 elderly patients in 15 long-term care hospitals in B and K city. Data were collected from February 14 to March 30, 2015, and analyzed by t-rest, ANOVA, Scheff's test, Pearson correlation coefficients, and stepwise multiple regression. According to the results, there were significant differences in adjustment by religion, marital status, economic status, and perceived level of difficult problems. Adjustment was positively related to satisfaction and self-esteem. In addition, a negative correlation was observed between adjustment and depression. Meaningful variables that influenced the adjustment of elderly patients were depression, satisfaction, self-esteem, and religion. These factors accounted for 53.5% of the total variance in adjustment of the elderly patients in long-term care hospitals, and depression was the most influential factor. In conclusion, development and implementation of effective programs and strategies to reduce depression and to increase satisfaction with care and self-esteem is needed in order to enhance the adjustment of elderly patients in long-term care hospitals.

This study is a descriptive survey research on nursing workers at long-term care hospitals, who are largely divided into nurses and nurse aides, to identify the factors that affect their turnover intention. From August 12 to 16, 2022, the survey was conducted for 146 nursing workers in four long-term care hospitals located in G city. The survey results indicated that there were differences in their turnover intention depending on their age, religion, marital status, educational level, average monthly salary, job type, duty pattern and turnover experience, of all general characteristics (p<.05). Turnover intention had a significant positive correlation with job stress (r=.51, p<.001) and burnout (r=.62, p<.001), and had a significant negative correlation with organizational commitment (r=.-56, p<.001). Organizational commitment had a significant negative correlation with job stress (r=-.25, p=.002) and burnout (r=.-.67, p<.001), while burnout had a significant positive correlation with job stress (r=.56, p<.001). Factors influencing the nursing workers' turnover intention included job stress (β=.32, p<.001), organizational commitment (β=-.30, p=.001) and education level (β=.17, p=.022), with an explanatory power of 49.6%. Based on the results of this study, it is considered that efforts to improve the working environment for nursing workers at long-term care hospitals are needed by reducing their job stress and improving organizational commitment in order to reduce their turnover intention.

This study developed a Recurrent Neural Network model implemented through Long Short-Term Memory (LSTM) that generates long-term tidal level data at Busan Port using tide observation data. The tide levels in Busan Port were predicted by the Korea Hydrographic and Oceanographic Administration (KHOA) using the tide data observed at Busan New Port and Tongyeong as model input data. The model was trained for one month in January 2019, and subsequently, the accuracy was calculated for one year from February 2019 to January 2020. The constructed model showed the highest performance with a correlation coefficient of 0.997 and a root mean squared error of 2.69 cm when the tide time series of Busan New Port and Tongyeong were inputted together. The study's finding reveal that long-term tidal level data prediction of an arbitrary port is possible using the deep learning recurrent neural network model.

This study aims to investigate the stress factors of students in Dental Hygiene Department who will soon take the national examination, corresponding countermeasures and relationship of internal and external personality. On the basis of the results from investigation, this study will identify the methods to effectively cope with stress and to take the national examination with more positive thinking for the students and faculty members in Dental Hygiene Department, who have to pass the difficult test, the national examination. The structured questionnaires were given to junior students in Dental Hygiene Department in three colleges, to identify the stress factors, methods to deal with stress and A/B personality types. For the stress factor by field, the M college showed significantly higher stress about curriculum and assignment than the C college. In the stress factor analysis by item, the lack of information on national examination in the test area, all items in learning environment, a quantity of assignment that doesn't help the preparation of national examination in the assignment area, and lack of information on employment in job area demonstrated the significant difference(p<0.05). For the methods of subjects to deal with stress, several subcategories of long-term and short-term adaptation had significance. In case of the methods to deal with stress by personality type, B type in the short-term adaptation method in M college and A type in the long-term adaptation method in C college were significantly higher(p<0.05). As for the correlation between the population sociological features and stress factors by personality type, health status had the high correlation with test in the test area. In other areas, the travel hours to school showed the significant correlation. The higher the records were, the longer the travel hours were and the better the health status was, the higher the long-term adaptation method scores were. Moreover, the personality of A type showed the higher scores in the long-term adaptation method than that of B type. The health status and personality type showed the significant correlation(p<0.05). In conclusion, it is required to prevent any situations b identify the personality type and stress reasons of the students in Dental Hygiene Department who will take the national examination soon. The additional requirement is the continuing interest and counseling of faculty members to help students to cope with stress with positive attitude.

The concentrations of $NO_2$ were measured to estimate a new developed long term exposure $NO_2$ sampler at Pusan City considering the meteorological factors from May to July, in 1994. The monthly mean concentration of $NO_2$ was 15.9 PPb and 36.2 ${\mu}\ell$/day $NO_2$ and their high values were shown in the downtown of Pusan City which show potential pollution due to the increase of traffic activities and micrometeorological factors In and around the City. As a result of statistical correlation between $NO_2$ concentration by new sampling method and $NO_2$ concentration by the handy air sampler and chemiluminescent nitrogen oxides analyzer, 1994, correlation coefficients were high(r=0.93) and showed more than 0.88 value in the high concentration data set, which was arbitrarily divided into 30${\mu}\ell$ $NO_2$ concentration in an attempt to further investigate these relationships. Therefore, use of new developed long term exposure $NO_2$ sampler is good for $NO_2$ measurement and valuable for estimation of air quality in the urban and Industrial area.
