The purpose of this study was to examine relationships among job satisfaction and positive psychological capital and self-leadership in general hospital nurses and to provide the basic data for the development of job satisfaction intervention programs. The data were collected from 120 nurses working in the six general hospital located S and Y city using self-reported questionnaires and April 1 2017 to April 15 2017. The data were analyzed by descriptive statistics, T-test, ANOVA, Scheffe, Pearson's correlation coefficient, and multiple regression with SPSS 20.0 program. Job satisfaction was found to be in a significant positive correlation with positive psychological capital and self-leadership. The result of the multiple regression indicates that positive psychological capital and self-leadership predict 27.5%(F=23.51, p<.001) of job satisfaction. Therefore it is necessary to develop convergence program to strengthen the job satisfaction of clinical nurses'.

The purpose of this study was to examine relationships among resilience and job Stress, turnover intention and vitality in general hospital nurses and to provide the basic data for the development of resilience intervention programs. The data were collected from 140 nurses working in the four general hospital located S and Y city using self-reported questionnaires and February 1 2017 to February 17 2017. The data were analyzed by descriptive statistics, T-test, ANOVA, Pearson's correlation coefficient, and multiple regression with SPSS 20.0 program. Resilience was found to be in a significant positive correlation with job stress, turnover intention and vitality. The result of the multiple regression indicates that work pattern and vitality predict 31%(F=10.01, p<.001) of resilience.

The purpose of this study was to investigate the effect of character strength and self-efficacy on subjective happiness of adult learners of distance nursing education. The subjects were 261 adult learners of Bachelor Science in nursing course for Registered Nurse of a national open university. The mean score of subjective happiness of subjects was a little lower. 'Transcendence and Humanity' among Character Strength was the highest and 'Justice' was the lowest. Multiple regressions showed that positive integrity, hardiness, and perceived health status explained 38.0% of subjective happiness and positive integrity was the main influencing factor. The learning supporting strategies focusing on reinforcing these factors are needed to improve the subjective happiness of nurses who are continuing their learning through distance education.

As external data have become important corporate information resources, there are growing needs to combine them with internal data. This paper proposes an ontology-based scheme to combine external data with multi-dimensional databases, which shall be called multi-dimensional event ontology. In the ontology, external data are represented as events. Event characteristics such as actors, places, times, targets are linked to dimensions of a multi-dimensional database. By mapping event characteristics to database dimensions, external event data are shared via multi-dimensional hierarchies. This paper proposes rules to synchronize information sharing in multi-dimensional event ontology such as upward event information sharing, downward event information sharing and complex event information sharing. These rules are implemented using Protege. This study has a value in suggesting Big Data information sharing processes using an event database framework.

This purpose of this study was to identify factors influencing performance about practice of infections management by child care center teachers about respiratory tract infection. The participant were 432 teachers working in child care center. Data were collected from July 2 to August 20, 2015 through a self-report questionnaire survey. The data was analyzed using the SPSS/WIN 18.0 program with descriptive analysis, t-test, one-way ANOVA, Pearson's correlation coefficient and Stepwise multiple regression analysis. Knowledge about causes and symptom of respiratory tract infections(${\beta}=.096$, p<.001),parenting experience(${\beta}=-1.993$, p<.001), and nursing knowledge(${\beta}=-.371$, p<.001) had significant positive effects on the practice of infection management. Explained variance for the practice of infection management was 43.4% and nursing knowledge was the most significant factor in the practice of infection management of child care center teachers.

The specific purpose was to determine the effect of walking on the body composition and hematological index of hemodialysis patients in order to confirm the relationship between activity and health level of hemodialysis patients. The research method is a cross-sectional descriptive survey conducted in hemodialysis patients.The subjects were 66 hemodialysis patients undergoing hemodialysis treatment in B city. As a result of the study, walking was decreased in hemodialysis patients, and there was a difference in hematological index according to walking, but there was no difference in body composition. As body weight increased, skeletal mass, body fat mass, body mass index, abdominal fat percentage, basal metabolism, and protein increased, but total cholesterol and high-density cholesterol decreased. This study proposes to expand the number of subjects of hemodialysis patients to investigate by adding nutritional intake in addition to walking, body composition and hematological index.

Objective: This study is a descriptive research study aimed to identify the needs of self-reinforcement education by applying IPA(Important-Performance-Analysis) techniques to develop the health care empowerment programs for the elderly with hypertension. Methods: The subjects of this study were 128 elderly people with hypertension over 65 years of age in areas A and B, and data were collected from 6 researchers and research assistants from May 11 to June 26, 2020. The collected data were analyzed by frequency analysis, descriptive statistics, and t-test. Results: Although the question with the highest education demands were 'I try to get my health care providers to my preferences for my treatment.' and with the greatest difference between importance and performance is the question 'I take my commitment to my treatment seriously'. Conclusion: From the results of this study, it is considered that a strategy that reflects the components of educational needs and healthcare empowerment is necessary when developing healthcare empowerment programs for the elderly with hypertension.

This study investigated predictors of the behavior related to particulate matter in nursing students. The participants in this descriptive study were 186 nursing students at K university in G city from May 1 to 14 in 2018. Collected data were analyzed by t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple linear regression using SPSS WIN 18.0 program. The level of knowledge(10.6/15), attitude(59.94/75) and behavior(42.56/60) were relatively high. The significant predictors of the behavior were attitude(β=.591, p<.001), smoking(β=-.134, p=.049) and respiratory disease(β=.133, p=.025), and explained 40.1% of it. Educational programs to enhance nursing students' health promoting behaviors against particulate matter must be focused on attitude change.

The Transmitter part of single RF transceiver chip for an extended GSM handset application was circuit-designed, fabricated adn evaluated. The RF-IC Chip was processed by 0.8${\mu}m$ Si BiCMOS, 80 pin TQFP of $10 {\times} 10mm$ size, 3.3V operated RF-IC reveals, in general, quite reasonable integrity and RF performances. This paper describes development resuts of RF transmitter section, which includes IF/RF up-conversion mixer, IF/RF polyphase and pre-amplifier. The test results show that RF transmitter section is well operated within frequency range of 880~915MHz, which is defined on the extended GSM(E-GSM) specification. The transmitter section also reveals moderate power consumption of 71mA and total output power of 8.2dBm.
