This study attempts to investigate the relations between the types of communication, the job satisfaction. and the nursing performance of the staff nurses. The subjects of this study were the 114 nurses working in general wards, intensive care units, and the emergency rooms of the general hospital in Kyongbuk province. They were asked to answer the questionnaires as regards the types of communication and job satisfaction, and their performance of nursing, and these were evaluated by the head nurses, and their direct seniors. The data were collected for 10 days from the September 17 to 26, 2002. According to the purpose of the study, descriptive analysis, ANOVA. Pearson correlation coefficient, and stepwise multiple regression were applied for the data analysis using SPSS 10.0. The results are as follows : 1. The types of communication of staff nurses showed that the upward communication was $3.12\pm0.56$. the downward communication was $3.56\pm0.42$. the horizontal communication was $2.98\pm0.44$. and the informal communication was $2.59\pm0.49$. It showed that the most frequent communication was the downward communication. 2. In terms of the job satisfaction, there was significant difference according to the length of the period working for one ward (F=5.95, p=0.003), 3. The performance of nursing was significantly different according to the age (F=23.52, p=0.000), the working duration as a nurses (F=21.9, p=0.000), the types of nursing unit (F=5.33, p=0.002), and the working duration in present nursing unit (F=15.87, p=0.000). 4. In terms of communication type, the job satisfaction was associated with quality of the upward communication (F=6.23, p=0.003), the downward communication (F=5.78, p=0.004), and the horizontal communication (F=11.73, p=0.000) There were no association between the types of communication and the performance of nursing. 5. There was a positive correlation between the communication and the job satisfaction. And the downward communication (r=0.398) showed the greatest correlation with the job satisfaction. There was no statistically significant correlation between the communication and the performance of nursing. And the upward communication (r=-0.058) showed a negative, though not significant correlation with performance of nursing. 5. There was a positive correlation between the communication and the job satisfaction. And the downward communication (r=0.398) showed the greatest correlation with the job satisfaction. There was no statistically significant correlation between the communication and the performance of nursing. And the upward communication (r=-0.058) showed a negative. though not significant correlation with performance of nursing. 6. The stepwise multiple regression result showed that the downward communication accounts for $15.8\%$ (p=0,000) of the job satisfaction.

The purpose of this study was to survey the ability of nurses to perform endotracheal suction to provide basic data on correct endotracheal suction. The participants in this study were 181 intensive care unit nurses in two university hospitals and one general hospital located in Daegu, one university hospital and two general hospitals located in Pohang, one university hospital located in Gyeongju. These data were collected from February 1, 2001 to March 10, 2001 using self reported questionnaires. The study instrument, which was developed by these investigators, included questions on general characteristics and performance of endotracheal suction. The results of this study are as follows : 1. Of the Participants 71.3% recognized correct endotracheal suctioning and 23.2% did not. 2. The greatest number, 57.5%, acquired knowledge about endotracheal suctioning at conferences on practice or education for staff. 3 There were significant differences in scores on performance of endotracheal suction according to department (F=2.60, P=.05) and hospitals (F=3.24, p=.01) among the general characteristics. 4. Slightly less than half of the participants, 47.8%, averaged correct scores for endotracheal suctioning procedures. Ventilator $O_2$ supply had the highest score (84.0%), normal saline exchange time, the lowest (14.4%) From the results, we suggest that education is needed to increase the knowledge and correct performance of endotracheal suction. Further study including direct observation of Performance of endotracheal suction is also needed.

The purpose of the present study was intended to assess fatigue symptoms of nurses working at special part(operating room, intensive care unit, emergency room) and ward in general hospitals, and to reveal its related factors. The self-administered questionnaires were given to 393 nurses employed in 3 participating hospitals located in Daejeon City. As a results, the special part workers had higher scores of fatigue symptoms than the ward workers. Multiple stepwise analysis revealed that the factors of influence on fatigue symptoms in the special part workers included subjective health status, age and job satisfaction, and in the ward workers, the factors of influence on fatigue symptoms included subjective health status, sleep hour, shift work and job satisfaction. In conclusion, the fatigue symptoms were higher in the special part workers than the ward workers, and its related factors were different from two worker groups.

The environment in the ICU leads to negative changes in a patient's usual sleep pattern and so contributes negatively to the patient's health condition as compared to patients in general wards. Therefore, it is thought that an important nursing intervention would be to identify the relation between noise and sleep patterns which play an important role in illness recovery. The purpose of the present study was to explore the relationship between noise in the ICU and the sleep pattern of patients admitted to the ICU. A descriptive correlation design was used to examine the relationship. Thirty-four subjects were recruited from a Medical ICU (MICU), Surgical ICU (SICU) and Coronary Care Unit (CCU) at a large university hospital in Suwon. Data were collected from September 28 to October 31 in 1999. In the present study, noise was categorized into noise level and patients' perception of noise. The objective noise level was measured using the A-Weighted Sound Level Meter. The patients' preception of noise was measured using a self-reported questionnaire developed by the researcher. Sleep patterns in this study includes both quantity and quality of sleep. These were measured using open ended questionnaires and the 'Korean Sleep Scale A' developed by Oh, Song, Kim(1998). The data was analyzed using the SPSS-WIN to test the research question, Pearson product moment correlation coefficient was run. Ancillary analysis were conducted with demographic variables to determine their relation to the main study variables. For the ancillary analysis, t-test and one-way ANOVAs were performed. The results of the present study are summerized as follows : 1. The total mean of objective noise level (10pm-6am) was 56.2dB. The means for night time noise level in individual ICUs for the SICU, MICU and CCU, were 58.7dB, 58.6dB and 48.3dB, respectively. The total mean for patients' noise perception was 42.8 out of a maximum possible score of 76. For item means of noise perception, the one ranked highest was "conversations between doctors and nurses" (3.2). The one ranked lowest was "noise from the radio" (1.2). Regarding the degree of perception for each type of noise source, the one ranked highest was "equipment noise" (2.6), the second was "conversation between medical staff" (2.4), the third was "conversation between patients, caregivers and visitors" (2.3), and the one ranked lowest was "environment noise" (1.8). 2. Looking at quantity of sleep of ICU patients, the mean nocturnal sleep time was found to be 4.9 hours. The total mean of sleep quality for ICU patients was 21.0 out of a maximum possible score of 40. 3. The relationship between perception of noise and quantity of sleep was statistically significant(r= - .41, p<.05). The relationship between perception of noise and quality of sleep was also statistically significant(r= - .47, p<.01). The results of the study indicate that personal perception of noise is related to sleep patterns. Therefore, it is suggested that nursing interventions be developed to reduce the degree of personal perception of noise and, thus, decrease sleep pattern disturbances in patients in the ICU.

This study was performed to find out the differences between noise levels of hospital wards and the nurses efforts for noise management in some general hospitals. The hospital wards selected were the intensive care unit(ICU), the emergency room(ER), the nursery room(NR), the internal medicine(IM), the general surgery(GS) among the 5 general hospitals located in Seoul. The data were collected from August 3 to September 13, 1999 through questionnaire survey and noise measurement in each nursing station of hospital wards. Data analysis was done by SPSS 8.0 package among the 305 questionnaires and 24 hours monitored noise levels. Frequency, Chi-square and ANOVA test were used. The study results were as belows: 1. The noise level measured by 24 hours monitoring survey were exceeded on the standard limit in all the hospital wards. Data also showed that noise levels were significantly different in each ward among the three shifts working duties. 2. The subjects were all female nurses. They were mostly working in the ICU ward(28.9%). They were 26~30 years old (43.9%), junior college graduates(57.0%), working for 1~5 years(55.1%) as staff-nurse(85.6%). There were no significant differences between hospital wards and general characteristics of nurses. 3. The noise levels perceived by nurses were regarded as 'Highly noisy'(56.4%), especially during the 11:30 and 15:30 (30.2%) o'clock. Data also showed that noise education was not ever given to nurses(89.9%). Nurses also responded that they hardly put an effort to reduce noise level(54.8%). However, there were significant differences between wards and noisy working time, experience of noise education and level of effort for noise reduction. 4. Nurses also perceived the ventilator alarm and EKG-alarm as the most disturbing sounds in the ICU, human voice and telephone ringing in the ER, human voice and EKG-alarming in the NR, human voices and telephone ringing in IM and GS both wards respectively in order. There were significant differences between hospital wards and noise making factors. 5. Nurses were shown that they regarded highly 'Sound reduction of the human voice', 'Careful handling on medical instruments', and 'Immediate appliances on alarming materials' as the practical method for noise management. There were significant differences between hospital wards and behavioral practical efforts for noise management. According to that results, the statistical differences were shown in the 24 hour monitored noise levels in each ward. Also, nurses perceived the noise severity differently and they approached variously on the practical efforts for noise reduction in each ward. Thus, author thinks that concrete and systematic endeavor will be necessary for noise reduction and management in hospitals for better working and healing environment for both of patients and staffs.

Purpose: This study was aimed at providing scientific evidence for minimizing ventilator-associated pneumonia(VAP) by identifying appropriate timing of exchange of circuit for mechanical ventilator that is well suitable for the medical environment of intensive care units of hospitals in Korea. Method: This was a quasi-experimental study with a convenience sample of 19 adult subjects aged over 18 years who were admitted to the NS ICU of C university hospital, and placed on mechanical ventilator. The subjects were placed in two groups, compared on the incidence rate of VAP after they received exchange of circuit either at 1-week interval (N =10) or 2-week interval (N = 9). Result: 1) When considering 1000 days as the standard unit of analysis for incidence, the incidence rate of VAP was 7.19 cases at the 1-week cycle exchange group and 15.23 at the 2-week cycle exchange group, showing no statistically significant difference between the two groups. 2) There were a total of 3 types of bacteria isolated from the patients with VAP, including 2 cases with P. aeruginosa, 1 case with Streptococcus group F and A. baumannii. Conclusion: With thorough hand washing and strict management of tracheal tube of mechanical ventilator as well as use of tracheal intubation techniques, exchange cycle of circuit of mechanical ventilator by nurses may be changed from 1-week to 2-week interval.

Purpose: To investigate factors that may affect the method of feeding among preterm infants at 4 weeks after discharge. Methods: This study included 222 mother-infant dyads born before a gestational age of 37 weeks. The feeding method and general medical characteristics of the participants were assessed at 4 weeks after discharge using a structured questionnaire. Multinomial logistic regression analysis was used to examine which factors were associated with breastfeeding at home. Results: Of the 222 infants who qualified for the study, 71 (32.9%) continued to receive breastmilk at 4 weeks post-discharge. Multinomial logistic regression analysis showed that breastfeeding at 4 weeks post-discharge was associated with higher breastfeeding self-efficacy, vaginal delivery (experience), direct breastfeeding in the neonatal intensive care unit (NICU), gestational age between 30 and 34 weeks, and breastmilk consumption in the NICU. The following factors were associated with mixed feeding at 4 weeks post-discharge: being employed, having higher breastfeeding self-efficacy, and direct breastfeeding in the NICU. Conclusion: NICU nurses should provide opportunities for direct breastfeeding during hospitalization and support breastfeeding to enhance breastfeeding self-efficacy. These factors may help to ensure the continuation of breastfeeding after discharge. Moreover, factors that affect breastfeeding should be considered when providing interventions.

Purpose: Malnutrition affects all age groups, but older adults are particularly more vulnerable to nutritional deficiencies. This study evaluated the age-specific factors affecting malnutrition in hospitalized older adults. Methods: A retrospective study was conducted on inpatient elderly people who received artificial nutrition from 2010 to 2017. Data of demographics, diagnosis, type of nutrition therapy, number of comorbidity, fall risk assessment, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) score, and intensive care unit admission were collected. Malnutrition was defined as a body mass index (BMI) of less than 18.5 kg/m². Patients were classified as the young-old (65~74 years old), the old-old (75~84 years old), or the oldest-old (85 years old or older). Results: A total of 7,130 older adults were included, and 4,028 patients were classified as the young-old, 2,506 into the old-old, and 596 into the oldest-old. Proportion of malnutrition was higher in the oldest-old compared to the other groups. In multivariate analysis, parenteral nutrition, alcohol, and high risk of falls were factors affecting malnutrition in all groups. Parenteral nutrition and alcohol in the young-old, high risk of falls in the old-old, and male sex in the oldest-old were the factors affecting malnutrition by the age group. Conclusion: Older age was the most significant factor affecting malnutrition. Specific strategies by age are needed to improve nutritional status in hospitalized older adults as influencing factors for malnutrition vary among different age groups.

The purpose of this study was to investigate how attitude, subjective norm, and perceived behavioral control affect nurses' pressure ulcer (PU) prevention behavior among general hospital nurses based on the theory of planned behavior. A total of 111 nurses in four general hospitals in Korea participated in this study and replied to a survey on attitude, subjective norm, perceived behavioral control, and behavior regarding PU prevention. Data were analyzed with multiple regressions by all participants, education level, working department, and hospital size group. In all participants, the more positive attitude and the higher subjective norm, the more PU prevention behavior. However, in the group of 'more than bachelor degree' and 'tertiary hospital', the more clinical experience, the more behavior. In the group of 'surgical ward & intensive care unit', the higher attitude, the more behavior. In the group of 'more than bachelor degree', the higher subjective norm, the more behavior. Therefore, personalized and tailored intervention for nurses may be provided depending on nurses' education level, work department, and hospital size to enhance PU prevention behavior by means of improving nurses' attitude, subjective norm toward PU prevention.
