Background: Aortic diseases tend to involve the entire aorta. Hence, there is the constant possibility of the need for a secondary operation at the remnant aorta. This study analyzed our cases of secondary aortic surgery in order to determine its characteristics and problems. Material and Method: Between April 2003 and June 2007, 12 patients (6 male and 6 female) underwent thoracoabdominal aortic replacement as a secondary aortic operation. Their clinical courses were analyzed. Four of the patients underwent lower thoracobadominal aortic replacement under the normothermic femorofemoral bypass, and the others underwent an entire thoracobdominal aortic replacement under deep hypothermic circulatory arrest. Result: There was no death or paraplegia. As local complications, there were 3 cases of wound infection and 2 cases of an immediate reoperation caused by bleeding and one case of delayed wound. revision for a contaminated perigraft hematoma. As a systemic complication, there was one case of renal insufficiency, which required hemodialysis and one case of respiratory insufficiency that needed prolonged ventilator care. The mean admission period was $30{\pm}21$ days. All the patients were followed up for $626{\pm}542$ days without reoperation or other problems. Conclusion: Using properly selected patients and a careful approach, thoracoabdominal aortic replacement can be performed safely as a secondary aortic surgery.

Purpose: This study was conducted to identify subjective attitudes towards terminal patients in nursing students who had clinical practice. The types of subjective attitude were classified by applying Q methodology. According to those types, basic reference data for the development of educational programs were provided. Methods: Thirty-four final Q samples were selected, and Q classification with a nine-point scale was performed with P samples of 43 nursing students. A key factor analysis was conducted with the collected data using the PC QUANAL program. Results: Nursing students' attitudes towards terminal patients were grouped into three types. The total variable was 49.96%. Students with Type 1 ("wish for life-sustaining medical treatment") thought that terminal patients accurately understood their medical condition and wanted to prolong their lives. Others with Type 2 ("need for service and support") believed that a multidisciplinary nursing system needs to be established to help terminal patients prepare for death. Students with Type 3 ("awareness and acceptance of death") thought that terminal patients wanted to die with dignity at a hospice unit. Conclusion: This study analyzed various types of attitude towards terminal patients, as perceived by nursing students with clinical training experience. Development of educational programs for each attitude type analyzed in this study could contribute to systematic training programs for nursing students caring for terminal patients.

Purpose: The Assessing Care Of Vulnerable Elders project has developed indicators for the quality of the end-of-life (EOL) care. However, family members of cancer patients may have a different view on the quality indicators (QIs) established by health care experts. We evaluated the QIs from the family members' perspective. Methods: The information used in this study was gathered by surveying family members of cancer patients who were admitted to the inpatient hospice ward in Korea. A cross-sectional anonymous questionnaire was distributed to 120 potential respondents from July to October 2009. We included 69 responses in this study (effective response rate, 57.5%). Statistical analysis was performed by using SPSS for Win ver. 14.0, with independent t-test and Pearson's chi-square test. Results: Among QIs for good hospice care, families agreed the most on "Medical examination by the palliative care team or specialist" (88.4%) and "Dying in the family's presence" (88.4%). They agreed the least on "Discussing cardiopulmonary resuscitation with patients" (15.9%). Among QIs for bad hospice care, "Occurrence of fall or pressure ulcer are undesirable" showed the highest agreement rate (94.2%). The lowest agreement rate was 11.6% on "Dying in the hospital is undesirable." In addition, women, patients who were aware of their prognoses, and people with a high socioeconomic status tended to agree more on the QIs. Conclusion: Patients' families did not agree on some of the QIs recommended by previous studies. Family members' characteristics were related to their opinions on QIs.

Purpose: The purpose of this study was to describe the components and content of nursing intervention studies on mother-infant interactions and to present strategies for future studies. Methods: Four electronic databases in the Korean language were searched to identify studies done between January 1998 and December 2011. The search yielded 145 articles. From these articles, 19 studies met the inclusion criteria. Results: Mother-infant interactions in these studies were found to include verbal and non-verbal communication basic for optimal growth and development of the child. Six kinds of interventions for mother-infant interactions were identified as follows: sensory stimulation, education program, whole body massage, kangaroo care, visiting support, and music therapy. Conclusion: Further studies with well designed clinical trials need to be done in the area of child nursing to provide evidence based data for the development of strategies to promote positive mother-infant interactions.

Delirium is an organic psychiatric syndrome characterized by an acute onset, prominent disturbance of consciousness and cognitive impairment with fluctuating course. Although there is not a clear consensus concerning the optimal classification system for delirium subtypes, Lipowski(1983) firstly classified delirium by psychomotor activity, namely hyperactive, hypoactive, and mixed. According results of several following studies, prevalence of hypoactive delirium were not less than that of hyperactive delirium. But a diagnosis of hypoactive delirium often missed, which is most frequently misdiagnosed as depression and dementia. Hyperactive delirium can be caused by alcohol or benzodiazepine withdrawal, would be related with excessive dopamine and cholinergic deficiency, and is more responsive to high-potency antipsychotics therapy. Hypoactive delirium would be caused by metabolic encephalopathy, and tends to present a less responsiveness to antipsychotics and poorer overall prognosis with a prolonged duration of admission than hyperactive delirium. Delirium is not a homogenous syndrome. Because of different subtypes, it may have dissimilar underlying pathogenetic pathways. So different treatment strategies between various subtypes may be needed.

South Korea is an aging society with 10.9 percent of its population over 65 years of age, and the aging population naturally leads to a surge in elderly care costs. Compared to general hospitals and other hospitals that have systematic management strategies in an environment of intensifying hospital competition, the design and management strategies of nursing hospitals are insufficient due to the hospital's characteristics of long-term hospital admission and treatment. In this study, We conducted a symbol mark color and form analysis of nursing hospitals to establish a design strategy to meet the increasing demand on nursing hospitals. The subjects of the study were 131 hospitals that received the first grade of nursing hospitals in Korea, and each symbol mark was collected to analyze its form and color. Analysis of the form of symbol revealed that the most anthropogenic symbols were made with artificial objects, and among them, the number of symbols with crosses, hearts and human forms were higher. The color analysis showed that more than 50% of symbols consisted of two colors and the main colors were blue and green. It is expected that this research data will be used as a reference in the design of the symbolism of nursing hospitals, which will help consumers choose and develop strategies for hospital management in order to compete with the ever-increasing demand of nursing hospitals and hospital competition.

Objectives: Although sleep paralysis (SP) has been known as one of the symptoms of narcolepsy, recently it has become recognized as occurring frequently in the general population. However, the prevalence of SP and its associated factors in patients with major psychiatric disorders remain unknown. This study investigated the prevalence of SP and a variety of associated experiences in those patients. Methods: The subjects were 160 psychiatric patients and 143 age- and sex-matched controls. The Korean version SP questionnaire as well as the Sleep-Wake Schedule, Epworth Sleepiness Scale and Insomnia Severity Index were administered to all the subjects. The patients were referred from Dong-A University Hospital and consisted of 74 diagnosed as schizophrenia (47.7%), 26 as bipolar disorder (16.8%) and 55 as major depression (35.5%). Results: Nearly 42% of the patient group and 39% of the control group had experienced at least one episode of SP in their lifetime, with no significant difference between the groups. However, the patient group had experienced SP more frequently than the control group. Among all subjects, no gender difference in SP incidence was found. The peak age of onset was in the range of 16-25 years for both groups. Over eight tenths of both groups reported hallucinations and over seven tenths of both groups experienced fear accompanying SP. Conclusion: This study shows that there is no difference in the lifetime prevalence of SP between psychiatric patients and the general population, whereas frequency of SP experience is higher in psychiatric patients. Terrifying hallucinations and fearful feelings frequently accompany SP in both groups.

Although National Health Insurance(NHI) in the South Korea has guaranteed access to health insurance coverage to virtually all the people, a significant portion of out-of-pocket spending can create substantial financial burdens for some beneficiaries, particularly those with low incomes. Previous studies have estimated the magnitude of out-of-pocket spending by types of chronic illness or in- and out-patients. Prior estimates, however, have not given a complete picture of the impact of health care costs on lower-income populations. The result from this study shows that 20 percent of beneficiaries in the lowest-income quintile spent more than twelve percent of their household equivalent income out-of-pocket health services, whether they were enrolled in a Health care services or not. In comparison, the beneficiaries in the highest-income quintile level spent only 2 percent of their income out-of-pocket on health care. Also, the regression analysis suggests that age, household income, number of chronic illness, type of hospital in addition to the number of usage may affect the size of out-of-pocket spending.
