PURPOSE: This study was performed to identify factors affecting terminal care performance of clinical nurses. METHODS: The participants in this study were 175 nurses working in hospitals in Daegu and North Gyeongsang Province. Data were collected using a self-reported questionnaire and were analyzed with the IBM SPSS WIN 19.0 program. RESULTS: Nurses' terminal care performance was significantly related with suffering experience, empathy ability and caring behaviors. Significant predictors for terminal care performance were their department, empathy ability and caring behaviors. These factors explained 43.52% of the variance in terminal care performance of clinical nurses. CONCLUSION: Our study results suggest that terminal care performance of clinical nurses can be strengthened by improving empathy ability and caring behaviors.

PURPOSE: Acute lower respiratory tract infections (LRI) are important causes of pediatric morbidity and mortality. Recently among the common pathogens causing acute LRI in children respiratory viruses are apparently increasing rather than bacteria and mycoplasma in Korea. This study was aimed to define the distribution of age, seasonal variation and clinical manifestation of respiratory virus in children. METHODS: All 328 children in Seoul, who had hospitalized at the Pediatric ward of Hanyang University (138 children), Hallym University (61 children) and Sungkunkwan University (129 children) for the treatment of respiratory diseases were studied from March, 1997 to February, 1998. In nasopharyngeal aspirates obtained from these patients viral agents were detected by virus isolation and/or antigen detection by indirect immunofluorescent staining. But the subjects who was not found respiratory virus were excluded, although respiratory symptoms were present. RESULTS: 1) One or more agents were identified in 328 subjects. 2) The pathogens identified were Respiratory syncytial virus (RSV : 44.7%), influenza A virus (25.6 %), parainfluenza virus (14.6%), influenza B virus (14.3%), adenovirus (4.3%) and two or more viruses (3%). 3) Infections with RSV, parainfluenza virus and influenza A and B virus occured in epidemics, while adenovirus was isolated sporadically throughout the study period. 4) Clinical patterns of viral LRI were pneumonia (39%), bronchiolitis (34%), croup (18%), acute pharyngitis (7%) and asthma (2%). CONCLUSIONS: RSV was the most important in viral respiratory tract infection in children. Clinical manifestation and epidemic characterics were variable according to the agent. Accordingly, we should acknowledge the importance of respiratory virus to cause the repiratory tract diseases in children.

BACKGROUND/AIMS: To date, high-resolution manometry has been used mainly in the study of esophageal motility disorders and has been shown to provide more physiological information than conventional manometry, and is easier to interpret. This study aimed to evaluate the usefulness of high-resolution anorectal manometry (HRARM) compared to water-perfused anorectal manometry. METHODS: Patients who complained of chronic constipation with/without fecal incontinence underwent both water-perfused anorectal manometry and HRARM in a random order on the same day. Resting and squeezing pressures of the anal sphincter, attempted defecation, rectoanal inhibitory reflex, rectoanal contractile reflex, Rao's type of dyssynergia during attempted defecation, anal canal length, defecation dynamic parameters and measurement times for each method were analyzed. RESULTS: Of 14 patients, 7 were female, and the median age was 59 years (range 35-77). Indications for manometry were constipation (n = 8) and constipation with fecal incontinence (n = 6). Resting and squeezing pressures showed that the 2 methods were strongly correlated (resting pressure: r = 0.746, P = 0.002; squeezing pressure: r = 0.921, P < 0.001). In attempted defection, one equivocal case with water-perfused anorectal manometry was diagnosed type I pelvic floor dyssynergia with HRARM providing detailed pressure changes in internal and external anal spincters, and puborectalis muscle which improved assessment of anorectal disorders. The measurement time for HRARM was significantly shorter than that for water-perfused anorectal manometry (11.3 vs 23.0 minutes, P < 0.001). CONCLUSIONS: Both water-perfused anorectal manometry and HRARM are well tolerated and reliable methods of evaluating defecation disorders of pelvic floor dysfunction. HRARM is likely to provide better physiological information and to require a shorter measurement time compared to water-perfused anorectal manometry.

OBJECTIVES: The purpose of this study was to compare the physical activity level (PAL), the physical activity pattern and the energy expenditure in male and female elementary school soccer players using the accelerometer and the physical activity diary. METHODS: Twenty-five (male 11, female 14) elementary school soccer players (9–12 years) participated in this study. During their daily activities, they wore an accelerometer for seven days (five weekdays and two weekend days) and completed the physical activity diary for three days (two weekdays and one weekend day). PAL was calculated by using the physical activity diary and three equations (Pate Preschool, Freedson Children, and Freedson) were used to calculate the intensity of physical activity and energy expenditure from the counts of accelerometer. RESULTS: The average of physical activity by day of the week, CPM (Counts Per Minute) and METs (Metabolic Equivalents) were significantly higher in males (723.3 ± 149.2 CPM, 2.07 ± 0.18 METs) compared to females (505.6 ± 119.9 CPM, 1.79 ± 0.20 METs), but there was no significant difference in PAEE (Physical Activity Energy Expenditure) between the two groups (males: 15.5 ± 9.1 kcal/day, females: 11.5 ± 6.0 kcal/day). During weekdays, physical activity intensity was significantly higher in males compared to females at lunch time and training time than at other times. In both genders, the PAL was higher during weekdays (males 1.98, females 1.89) compared to weekend (males 1.62, females 1.61) (p<0.05). CONCLUSIONS: Our study observations suggest the necessity to develop an accelerometer equation for accurately evaluating the physical activity of elementary school athletes.

OBJECTIVE: Psychosocial dysfunction was a nettlesome of schizophrenia even in their prodromal phase as well as first episode and its relations with psychopathology were not determined. The aim of the present study was to examine whether the social and role function impairment was found in ultra-high risk for psychosis (UHR) individuals as well as first-episode schizophrenia patients and to explore its relations with psychopathology. METHODS: Thirty-seven normal controls, 63 UHR participants and 28 young, first-episode schizophrenia patients were recruited. Psychosocial functioning was examined by using Global function: Social and Role scale. Psychopathologies of positive, negative and depressive symptom were also measured. RESULTS: Social and role functioning in UHR were compromised at the equivalent level of those of first-episode schizophrenia patients. Multiple linear regression analysis revealed that social and role dysfunction was associated with negative symptoms in each UHR and first-episode schizophrenia group. CONCLUSION: These findings suggest that the significant impairment of social and role function may be appeared before the active psychosis onset at the level of extent to those of first-episode schizophrenia patients. The psychosocial intervention strategy especially targeting the negative symptoms should be developed and provided to individuals from their prepsychotic stage of schizophrenia.

OBJECTIVES: Accurate assessment of energy expenditure is important for estimation of energy requirements in athletic children. The objective of this study was to evaluate the accuracy of accelerometer for prediction of selected activities' energy expenditure and intensity in athletic elementary school children. METHODS: The present study involved 31 soccer players (16 males and 15 females) from an elementary school (9-12 years). During the measurements, children performed eight selected activities while simultaneously wearing the accelerometer and carrying the portable indirect calorimeter. Five equations (Freedson/Trost, Treuth, Pate, Puyau, Mattocks) were assessed for the prediction of energy expenditure from accelerometer counts, while Evenson equation was added for prediction of activity intensity, making msix equations in total. The accuracy of accelerometer for energy prediction was assessed by comparing measured and predicted values, using the paired t-test. The intensity classification accuracy was evaluated with kappa statistics and ROC-Curve. RESULTS: For activities of lying down, television viewing and reading, Freedson/Trost, Treuth were accurate in predicting energy expenditure. Regarding Pate, it was accurate for vacuuming and slow treadmill walking energy prediction. Mattocks was accurate in treadmill running activities. Concerning activity intensity classification accuracy, Pate (kappa=0.72) had the best performance across the four intensities (sedentary, light, moderate, vigorous). In case of the sedentary activities, all equations had a good prediction accuracy, while with light activities and Vigorous activities, Pate had an excellent accuracy (ROC-AUC=0.91, 0.94). For Moderate activities, all equations showed a poor performance. CONCLUSIONS: In conclusion, none of the assessed equations was accurate in predicting energy expenditure across all assessed activities in athletic children. For activity intensity classification, Pate had the best prediction accuracy.

OBJECTIVE: To access the pregnancy tendency and delivery in women aged 40 years and older. METHODS: From January 1999 to June 2001, 7882 deliveries were in Gacheon Medical School. Among them we compared 95 cases of pregnant women aged 40 years and older with 94 cases of those aged under 40 years as a control group. RESULTS: The parity was higher in women aged older than 40 years compared to control group. Number of prenatal special studies was higher in women aged older than 40 years (n=82) compared to control group (n=14). In modes of delivery and indications for c/sec, there were no difference in two groups. There were no difference in prenatal complications between two groups. But, number of cases related to placenta previa, myoma and anemia were increased in women aged older than 40 years. In postpartum complications, uterine atony and hysterectomy, postpartum bleeding and placenta accreta were higher in women aged older than 40 years compared to control group. CONCLUSION: For pregnant women aged 40 years and older, a careful approach and appropriate management will be necessary for good pregnant outcome.

Of all toxic inhalant exposures, chlorine is one of the most common toxic chemical inhalants. When acutely inhaled, it can be responsible for symptoms ranging from upper air way irritation to more serious respiratory effects. It can also deteriorate lung function and lead to death. Chlorine and its compounds such as chlorinated cyanurates and hypochlorites are commonly used in water disinfection. The chemical agents discussed in this article are sodium dichloroiso cyanurate and calcium hypochlorite which are the two most popular products for swimming pool chlorination. They are both strong oxidizing agents which are soluble in water. Between the above two alkali agents, acid-base interaction occurred and generated heat. And the acid drove the combination of hypochlorous and chloride ions to form chlorine gas. We have experienced, two boys who had inhalation injuries caused by an accidental explosion which occurred in a swimming pool by mixing two different chlorinating agents : sodium dichloroiso cyanurate and calcium hypochlorite. The children suffered from respiratory difficulties after the exposure. They both required intensive care management and one needed the support of mechanical ventilation
