PURPOSE: This study aimed to investigate the impact of nursing professionalism on the nursing performance and retention intention among psychiatric mental health nurses. METHODS: As a descriptive correlational study, this study sampled 206 psychiatric mental health nurses in six hospitals in Seoul and Gyeonggi area through convenience sampling. Data were collected from March 2 to 31, 2009 using a self-report questionnaire. The collected data were analyzed using SPSS WIN 16.0. RESULTS: In the subscales of professionalism, the 'Sense of calling' had the highest mean score while the 'Professional organization' had the lowest mean score. A significant positive correlation was observed in nursing professionalism, nursing performance and retention intention. According to an analysis on the impact of each subscale of nursing professionalism on nursing performance and retention intention, the 'Sense of calling' and 'Autonomy' were the most significant predictor variable. CONCLUSION: The results confirmed that the improvement of psychiatric mental health nurses' professionalism increases their nursing performance and retention intention and the 'Sense of calling' and 'Autonomy' are critical prediction factors. It is necessary to come up with a strategy which strengthens nursing professionalism in order to improve psychiatric mental health nurses' performance and retention intention.

PURPOSE: The aim of this study was to investigate the effects of occupational stress and coping styles on burnout of clinical nurses. METHODS: The participants in this study were 397 nurses, working at the hospitals in Seoul, Gangwon, and Gyongbuk provinces. Data were collected using a structured questionnaire from November, 2009 to January, 2010. The SPSS WIN 13.0 version program was used for data analysis. RESULTS: The most significant predictors of burnout were positive reappraisal and work load. Work load, resource inadequacy, role ambiguity, and indifference coping style positively correlated with burnout. Positive reappraisal and problem-focused coping styles negatively correlated with burnout. CONCLUSION: The study results indicate that it is important to reduce work load, resource inadequacy, and role ambiguity in nurses and to strengthen their positive reappraisal and problem-focused coping styles to prevent burnout. This could be achieved with job redesign, modification of shift work systems, and by offering burnout prevention program.
Surveys and Questionnaires

The objective of this study was to investigate the nutritional and health status of women industrial workers by working fields. One hundred forty eight (105 lead and 43 office) workers were recruited from March 2005 to October 2005. Information on age, education, smoking and drinking status were collected using questionnaire and nutrient intake and diet quality of workers were assessed by average of two-day 24 hr recall method. Biochemical indexes including blood lead level (PbB), indexes for iron status, serum calcium (Ca) and serum lipid profiles were analyzed from fasting venous blood or serum. Results showed that education level of lead workers was lower than that of office workers (p < 0.05), but nutrient intake levels were not significantly different by working fields. Overall nutritional status of the subject were good except for calcium, vitamin B2, C and folic acid intakes. PbB of lead workers were significantly higher than that of office workers while mean corpuscular hemoglobin concentration (MCHC) and serum Ca levels were significantly lower in lead workers. MCHC was positively correlated with zinc intake (r = 0.166) and serum Ca was positively correlated with vitamin C intake (r = 0.179). This study confirms that lead workers need extra care to keep their health and nutritional management especially for the nutrients known to interact with lead. Tailored nutrition education for workers at specific working fields needs to be more focused for the improvement of health status of industrial workers.

BACKGROUND: Several reports have indicated that heparin has a bronchodilative effect in asthma patients, and that it enhances airway smooth muscle contraction in vitro, protamine is known to inhibit or enhance contraction of tracheal smooth muscle. Thus the effects of protamine and heparin on airway smooth muscle contraction are not consistent. However, no report is available on the effects of enflurane on heparin and protamine tracheal smooth muscle contraction. We performed this study to evaluate the effects of heparin or protamine on the carbachol induced contraction of tracheal smooth muscle in the guinea pig. And we also evaluated the effects of enflurane on heparin or protamine induced tracheal smooth muscle contraction. METHODS: Isolated tracheal rings of the guinea pig were suspended in Krebs solution. Contractions were recorded isometrically using a transducer. Contraction was induced by carbachol (10-6 M) and then cumulative dose responses of heparin or protamine (0.006 mg/ml, 0.02 mg/ml, 0.06 mg/ml, 0.2 mg/ml, 0.4 mg/ml) and in heparin (E) group and protmine (E) group, enflurane (4.34%) was administered for 15 minute after carbachol adminstration. RESULTS: Contraction by carbachol was inhibited by level of heparin or protamine at concentrations of 0.2 mg/ml and 0.4 mg/ml. At an enflurane (4.34%) contraction was inhibited, and no further inhibition of contraction by heparin or protamine was observed. CONCLUSIONS: Heparin or protamine inhibited the tracheal smooth muscle contraction induced by carbachol at 0.2 mg/ml and 0.4 mg/ml, and no further significant inhibition of contraction by heparin or protamine was observed after enflurane administration (4.34%).

Purpose: The purpose of this study was to examine person-centered care, nursing professionalism, the nursing work environment, and empathy capacity among hospice ward nurses and to identify the factors affecting person-centered care. Methods: Data were collected using a self-report questionnaire completed by 120 nurses at 30 inpatient hospice institutions in South Korea from August 24, 2020 to September 8, 2020. The independent t-test, one-way analysis of variance, and Pearson correlation analysis were conducted using SPSS version 26.0. Results: The scores were 3.76±0.45 for person-centered care, 3.58± 0.47 for nursing professionalism, 3.24±0.57 for the nursing work environment, and 4.00± 0.46 for empathy capacity. There were positive correlations between the variables. Factors that influenced the person-centered care of hospice nurses were being a manager (β=0.20, P=0.002), high nursing professionalism (β=0.20, P=0.012), a better nursing work environ-ment (β=0.15, P=0.033), and high empathy capacity (β=0.51, P＜0.001). The explanatorypower was 65.3%. Conclusion To reinforce the person-centered care competency of hospice nurses, it is necessary to improve nursing professionalism, the nursing work environment, and empathy competency. Opportunities for nurses to practice independently must be expanded for nurses to develop nursing professionalism. Sufficient nursing personnel and material resources must be provided to nurses to cultivate a positive work environment.Empathy should be improved by implementing integrated education programs that include nursing practice situations.

PURPOSE: The purpose of this study was to examine if simulation training affects new graduate critical care nurses' knowledge, self-efficacy, and performance ability in emergency situations. METHODS: Forty new graduate critical care nurses were randomly assigned to either an experimental or a control group. The experimental group had didactic with simulation. The control group received only didactic without simulation about emergency situations. The data were collected before and after the training interventions. An independent t-test used for difference among variables. RESULTS: There were no significant demographic differences between the two groups or any differences on data collected knowledge, self-efficacy and performance ability. Following the training, there were significant performance ability scores (p<.001) among the nurses receiving didactic with simulation. There were no significant difference between the two groups relative to knowledge scores (p=.117), or the self-efficacy scores (p=.100). CONCLUSION: This study showed that simulation training for new graduate critical care nurses is useful to improve performance ability on emergency situations. Hence, providing simulation training to critical care nurses during an orientation period would improve quality of critical care nursing and help the new graduates nurse's adaptation.

Purulent pericarditis is an infrequent but fulminant and frequently lethal disease. Purulent pericarditis tends to occur as direct extension of bacterial pneumonia or empyema in past. In recently, purulent pericarditis tends to occur in adult via contiguous spread from an early postoperative infection after thoracic surgery or trauma, infection related to infective endocarditis, extension from a subdiaphragmatic suppurative source, and hematogenous spread during bacteremia. Endogenous causes of purulent pericarditis are frequently characterized as esophageal perforations. Common causes of esophageal perforations related to purulent pericaditis which usually develop in association with mediastinitis, pneumonia and empyema include corrosive esophagitis, complication after esophageal and tracheal instrumentation and Boerhaave's syndrome. There is very little reference to the development of pericarditis in associated with esophageal perforation which does not directly communicate with the pericardium. while, although most uncommon, it is well documented that the esophagus can perforate directly into the pericardium and produce pericarditis. We experienced a case of acute purulent pericarditis after esophageal and pericardial perforation by a small fish bone in a previously healthy man. The patient was treated successfully with systemic antibiotics and pericardiotomy.

OBJECTIVES: This study aims to compare quality indicators for the hemodialysis services between patients with health insurance and those with medical aid. METHODS: This study used data from sampled hospitals that provided a hemodialysis service. A total of 2287 patients were selected, and the information for hemodialysis service has been granted from medical record reviews. A multi-level regression analysis was used to examine the differences in process and outcome indicators for hemodialysis between patients with health insurance and those with medical aid. Process indicators were defined as: frequency of hemodialysis, hemodialysis time, erythropoietin (EPO) use, measurement of hemodialysis dose at least once a month, measurement of phosphate at least once every three months, and measurement of albumin at least once every three months. Outcome indicators were defined as: hemodialysis adequacy, anemia management, blood pressure management, and calcium, phosphate and nutrition management. The total scores for outcome indicators ranged from 0 (worst) to 4 (best). RESULTS: There was a significant difference in the measurement of hemodialysis dose at least once a month between patients with health insurance and those with medical aid (OR 0.66, 95% CI=0.43-0.99). However, frequency of hemodialysis, hemodialysis time, EPO use, measurement of phosphate at least once every three months, measurement of albumin at least once every three months, hemodialysis adequacy management, Hb> or =11 g/dL, blood pressure within the range of 100-140/60-90 mmHg, calcium x phosphate< or =55 g2/dL2 and albumin> or =4 g/dL were not significantly different between the groups. CONCLUSIONS: There were no significant differences in outcome indicators for hemodialysis between the groups. Further studies are warranted into the mechanism that results in no differences in the outcome indicators for hemodialysis.

A 70-year-old female Patient was admitted due to the impression of lung abscess via local clinic. Chest P-A showed air shadow containing huge mass lesion in the right lower lung field, pericardio phrenic angle. But the patient complained of only mild upper respiratioy tract infection symptoms and the laboratory tests were within normal limits. Barium enema and chest C-T taken right after barium enema were performad in suggesting of the diaphragmatic hernia. Barium tilled transverse colon and associated omentum were in the right anterior hemithorax surrounded by the hernial sac. The mass lesion shown in the chest P-A was compatible with the diaphragmatic hemia, Morgagni type. Operative reduction of the herniated bowel and simple closure of the diaphragm was performed.

BACKGROUND: The body temperature of a patient changes changes during general anesthesia and cholinesterase inhibitor is usually administered at the end of general anesthesia to reverse the neuromuscular blocker effect. We tried to evaluate the effect of temperature changes on the contraction of tracheal smooth muscle induced by acetylcholine (Ach) exogenously administered and neostigmine, cholinesterase inhibitor. METHODS: Isolated tracheal preparations(3 mm wide) of rabbit were mounted in organ baths filled with Tyrode's solution. Cumulative dose responses(isometric contractin) of Ach (10-6, 10-5, 10-4 & 10-3 M) & neostigmine (10-8, 10-7, 10-6, 10-4) at 37oC, 39oC and 27oC were measured with force displacement transducer and pD2 was calculated. RESULTS: Warming from 37oC to 39oC, contraction by Ach weakened significantly and contraction by neostigmine did not change significantly. Cooling from 37oC to 27oC, contraction by Ach were changed significantly and contraction by neostigmine, at low concentration, was inhibited significantly, but at high concentration, was not potentiated significantly. pD2 of Ach did not change significantly by cooling from 37oC to 27oC and decreased significantly by warming from 37oC to 39oC. pD2 of neostigmine was significantly reduced by cooling from 37oC to 27oC and did not change significantly by warming from 37oC to 39oC. CONCLUSIONS: Warming from 37oC to 39oC, the contraction of tracheal smooth muscle induced by Ach was decreased significantly,and cooling from 37oC to 27oC, contraction induced by neostigmine was decreased significantly at low concentration of neostigmine. But it is not sure wheter these effects can be observed in clinical practice when neostigmine is administered to patients,so further study is necessary.
