PURPOSE: This study aimed to investigate job satisfaction, organizational commitment and turnover intention among male nurses in South Korea. METHODS: Data were collected in May, 2013 and a total of 150 male hospital nurses participated in this study. Job satisfaction, organizational commitment and turnover intention were measured using a structured questionnaire. Collected data were analyzed using SPSS/WIN 20.0 for windows. RESULTS: There were statistically significant correlations between job satisfaction and organizational commitment (r=.74, p<.001), job satisfaction and turnover intention (r=-.56, p<.001), and organizational commitment and turnover intention (r=-.69, p< .001). There was a statistically significant difference in job satisfaction of participants according to education, work unit, and salary. Organizational commitment showed significant difference according to age, education, work unit, and salary. Turnover intention was significantly different according to duration of employment in the hospital, and salary. The most influential factor for turnover intention was organizational commitment (beta=-.69, p<.001). This factor accounted for 47.8% of the variance in turnover intention. CONCLUSION: The results of this study indicate that to reduce turnover intention for men in nursing, it is necessary to increase job satisfaction, and organizational commitment.

Dendritic cells (DCs) are key modulators that shape the immune system. In mucosal tissues, DCs act as surveillance systems to sense infection and also function as professional antigen-presenting cells that stimulate the differentiation of naive T and B cells. On the basis of their molecular expression, DCs can be divided into several subsets with unique functions. In this review, we focus on intestinal DC subsets and their function in bridging the innate signaling and adaptive immune systems to maintain the homeostasis of the intestinal immune environment. We also review the current strategies for manipulating mucosal DCs for the development of efficient mucosal vaccines to protect against infectious diseases.

PURPOSE: To analyze the clinical and radiographic results after revision total knee arthroplasty (TKA) using Nexgen(R) LCCK (Legacy(R) knee constrained condylar knee, Zimmer, Warsaw, IN) with allograft. MATERIALS AND METHODS: Twenty patients (21 knees) taken revision TKA were analyzed. The average age of the patients was 69.2 years old and the average of follow-up duration was for 2 year to 8 years 2 months (average 3 years 5 months). The clinical result and radiographic measurements were assessed using the Hospital for Special Surgery (HSS) knee rating score and the roentgenographic method of the American Knee Society. RESULTS: The mean interval from TKA to revision surgery was 6 years 4 months. In all cases, allograft was used. The average range of motion was increased from 93degrees to 107degrees, HSS score was increased from an average of 45 to 87 points. Postoperative femorotibial alignment was averaged 5.7degrees valgus. In all cases, radiolucency was below 4 scores and there was no loosening of implant. But, three radiopaque lines around a stem. There were wound dehiscence in 1 case and superficial infection in 2 cases. CONCLUSION: Satisfactory results were obtained in revision TKA using a NexGen(R) LCCK with allograft. But, this study is favorable for the long term follow-up.

OBJECTIVE: To evaluate the outcome of pregnancy in kidney transplanted women, and correlate this with the time of transplantation to conception. MATERIAL AND METHODS: We analyzed the outcome of 31 pregnancies from 21 allograft recipients at Kangnam St. Mary's Hospital, Catholic Medical Center from January 1990 through December 2000. For each reported pregnancy we reviewed obstetrical, medical and pediatric records. For children follow-up and for those whose obstetric procedures were taken in other hospitals, we did a questionarie and telephone interviews. RESULTS: Of the 31 pregnancies followed by us, there were 23 live-born offspring delivered by 21 mothers and 8 stillborn/abortuses, including five artificial abortuses. The mean gestational age at delivery was 36.18+/-0.6 weeks and the mean birth weight of the offspring was 2,525+/-137gm. Only 43.4% was delivered after 37weeks of gestation. Preterm delivery rate (delivered before 37weeks of gestation) was 56.5%. Common obstetric complications were intrauterine growth restriction (39.1%) preterm labor (35%), premature rupture of membrane (30%), preeclampsia (30%), and maternal complications were deterioration of renal function (5%) and rejection of allograft (18%) after delivery. Mean interval from transplantation to pregnancy was 4.7 years. Twelve pregnancies occurred within the first 2 years of transplantation, while 19 pregnancies occurred after that period. No difference was noted in neonatal body weight between 2 groups (p=0.824). There was no difference in mean interval from transplantation to pregnancy in the delivery group (5.21+/-0.9 years) vs. the abortion group (4.57+/-1.1 years) (p=0.207). All women continued with her medication during pregnancy, based on cyclosporine and/or azathioprine and steroids. No congenital anomaly was noted in the newborn. When follow up lately, one boy with neurofibromatosis and a girl with recurrent hematuria were noted. CONCLUSION: Although pregnancy in renal allograft patient is hazardous, good outcome can be expected if function of the allograft is good before conception.

Infection with invasive Shigella species results in intestinal inflammation in humans but no symptoms in adult mice. To investigate why adult mice are resistant to invasive shigellae, 6~8-week-old mice were infected orally with S. flexneri 5a. Shigellae successfully colonized the small and large intestines. Mild cell death was seen but no inflammation. The infected bacteria were cleared 24 hours later. Microarray analysis of infected intestinal tissue showed that several genes that are involved with the sphingosine-1-phosphate (S1P) signaling pathway, a lipid mediator which mediates immune responses, were altered significantly. Shigella infection of a human intestinal cell line modulated host S1P-related genes to reduce S1P levels. In addition, co-administration of S1P with shigellae could induce inflammatory responses in the gut. Here we propose that Shigella species have evasion mechanisms that dampen host inflammatory responses by lowering host S1P levels in the gut of adult mice.

During intraocular surgery including cataract, air bubbles occasionally enter the anterior chamber during irrigation. The influences of these air bubbles on the cornea endothelium, however, have yet to be known. The purpose of this study is to investigate the effects of bubbles on the rabbit corneal endothelium during irrigation and aspiration mode in experimental phacoemulsification. After anesthesia, the anterior chamber was irrigated and aspirated for 1 minute with balanced salt solution. The rabbits were then randomly divided into 4 groups. In group 1, corneal endothelial irrigation and aspiration were performed without air bubbles for 1 minute. In group 2, corneal endothelial irrigation was performed in the presence of air bubbles in the anterior chamber for 1 minute. In group 3, corneal endothelial irrigation and aspiration were performed in the presence of air bubbles in the anterior chamber for 1minute. In group 4, corneal endothelial irrigation was performed with silicone oil at 50 mmHg pressure in the presence of air bubbles in the anterior chamber for 1 minute. In group 1, the cornea endothelial cells showed normal F-actin without cell damage. In group 2, a ring shaped endothelial cell destruction area adjacent to the border was found along the margin of the air bubble. In group 3, similar ring-shaped lesion found in group 2 were observed but with more extensive cell destruction. In group 4, a partial number of cell to cell separation was found without endothelial cell destruction. In conclusion, air bubbles in the anterior chamber during irrigation with balanced salt solution showed destructive changes in rabbit corneal endothelial cell.

Obesity is an independent and modifiable risk factor for cardiovascular disease, and known as a core of the metabolic syndrome. Obesity has been largely diagnosed based upon anthrompometric measurements like waist circumference (WC) and body mass index (BMI). We sought to determine associations between anthropometric measurements and dyslipidemia in a community adult sample composed of 1,032 community residents (356 men, 676 women) aged 50 yr and over in Namwon, Korea. Blood tests for lipid profiles, including total cholesterol (TC) and HDL cholesterol (HDL) were performed, and dyslipidemia was defined as TC/HDL greater than 4. Anthropometric measurements included WC, waist-to-height ratio (WHtR), waist-to-hip ratio, and BMI. All anthropometric measures were categorized into quartiles and evaluated for associations with dyslipidemia. TC/HDL showed the significant associations with the anthropometric measures, independently of potential confounders. In women, increases of obesity indexes by quartile analyses showed linear increases of odds ratios for dyslipidemia (p values <0.01 by trend test). In men, except BMI, same patterns of association were noted. WC and WHtR were significantly associated with dyslipidemia in Korean adult population. As a simple and non-invasive method for a detection of obesity and dyslipidemia, anthropometric measurements could be efficiently used in clinical and epidemiologic fields.

Lung lavage is an accepted modality for treatment of pulmonary alveolar proteinosis. The procedure can be accomplished by the use of double lumen endobronchial tube, with lavaging of one lung while the other is ventilated. As lung lavage is an intentional drowning, particular attention must be paid to potentially serious complications such as severe hypoxemia. We report a case of lung lavage in a patient with secondary pulmonary alveolar proteinosis performed safely by careful monitoring of oxygenation and hemodynamics.

OBJECTIVES: An association between serum cholesterol concentration and violent behavior has been suggested, but has not been consistently demonstrated. This study was conducted in oreder to evaluate the relation between serum cholesterol concentration and violent behavior in psychiatric inpatients who had been admitted at Uijongbu St.Mary's Hospital, the Catholic University of Korea from January 1994 to June 1995. METHODS: We divided the 127 subjects into violent(35 subjects) and non-violent group(95 subjects). According to the percentile distribution of serum total cholesterol in healthy Korean adults, the subjects were classified into four subgroups:Group 1,subjects whose cholesterol concentrations were below 26% of percentile distribution, Group 2,from 26% to 50%, group 3, 51% to 75% and group 4, above 75%. In the four cholesterol subgroups, the authors examined the incidence of violent behaviors and suicidal attempts. Within the violent group, total aggression score of four cholesterol subgroups was compared. RESULTS: 1) Among the four cholesterol subgroups, there were no significant differences in the violent behavior. 2) within the violent groups, total violent score of the four cholesterol subgroups showed no significant difference. 3) Among the four cholesterol subgroups, there were no significant differences in suicidal attempt. CONCLUSION: When the serum cholesterol concentrations of psychiatric inpatient applied to the percentile distribution of serum total cholesterol in healthy Korean adult, no association was found between serum cholesterol concentration and violent behavior and suicide attempt.

BACKGROUND AND OBJECTIVES: With the currently available diagnostic procedure, hearing impaired children are diagnosed at an early age and hearing aids are fitted soon thereafter. Thus, appropriateness of using available correction methods for adult ears and ear models for determining and predicting hearing aid characteristics for these children need to be examined. The objectives of this study are to create a database of resonance frequency and length of external auditory canal (EAC) in all age groups and to adjust the peak frequency response of hearing aid system to take account of the changing resonance peak frequency as child gets older. MATERIALS AND METHOD: We studied 437 ears with no age limitation. We measured rear ear unaided response (REUR) with Rastronics frequency response analyzer and external ear canal length using silastic tube under microscopic or otoscopic finding. Statistical analyses were performed to determine age differences. RESULTS: Ear canal length increased with age, and an adult value was achieved by the age of 14 years. Resonance frequency decreased with age, and reached to an adult value by the age of 9 years. There was significant relationship between ear canal length and resonance frequency. CONCLUSION: Alteration in resonance frequency with age may have practical implications by affecting the insertion gain of hearing aid system in children. The data may be used as useful adjustment factors to correct the current hearing aid system in children.
