Purpose: To identify the type of disease-related stress experienced by women who received mastectomy for breast cancer using Q methodology. Method: Q sample included 30 statements obtained from literature and interviews with women with mastectomy. P sample consisted of 22 patients with mastectomy. The data were collected from November to December 2002 and analyzed using QUANL program. Result : Four types of disease-related stress experienced by women with mastectomy were found. Type 1 was manifested for a short duration following surgery and characterized by lowered self-esteem, feelings of emptiness and depression because of impaired body image. Type 2 was characterized by declined physical strength, resulting in frequent fatigue in the daily life and less intimate relationship with spouse. Type 3 was manifested by perfectionists with strong sense of self-pride who received or considered breast reconstruction surgery. Type 4 was reported by those who had long period of post-surgery. This type reported a strong sense of discomfort for wearing an artificial breast but didn't show any intention of trying breast reconstruction surgery. Conclusion: Women with mastectomy were found to experience different type of disease-related distress. Therefore, nurses should assess the type of stress the patient experiences following a mastectomy to provide appropriate nursing care.

Background B-type natriuretic peptide (BNP) has been shown to be strong mortality predictors in a wide variety of cardiovascular syndromes. Little is known about BNP in patients with acute respiratory distress syndrome (ARDS). We studied whether BNP can predict mortality in patients with ARDS. Method Echocardiographic study was done to all patients with ARDS, and we excluded patient with low ejection fraction (less than 50%) or showing any features of diastolic dysfunction. 47 patients were enrolled between December, 2003 and February, 2006. Parameters including BNP were obtained within 24h hours at the time of enrollment. Result Mean BNP concentrations and APACHE II scores differed between the survivors and nonsurvivors (BNP, $219.5{\pm}57.7pg/mL$ vs $492.3{\pm}88.8pg/mL$; p=0.013, APACHE II score, $17.4{\pm}1.6$ vs $23.1{\pm}1.3$, p=0.009, respectively). With the use of the threshold value for BNP of 585 pg/mL, the specificity for the prediction of mortality was 94%. The threshold value for APACHE II of 15.5 showed sensitivity of 87%. 'APACHE II + $11{\times}logBNP$' showed sensitivity 63%, and specificity 82%, using threshold value for 46.14. Conclusion BNP concentrations and APCHE II scores were more elevated in nonsurvivors than survivors in patients with ARDS who have normal ejection fraction. BNP can predict mortality. Further study should be done.

In the animal model of acute respiratory distress syndrome (ARDS) induced by N-nitroso-N-methylurethane (NNNMU) the secretory activity of alveolar type H cells during acute alveolar injury was investigated by determining phospholipid and pulmonary surfactant associated proteins in crude surfactant. The mechanism of the secretory change was studied by determination of DNA and RNA levels in the lung tissue. After induction of acute alveolar injury with NNNMU, pulmonary hemorrhage, atelectasis and gross hypertrophy were observed. Seven days after NNNMU treatment the level of total DNA in lung homogenate was increased markedly indicating that a hypertrophy was induced by cellular proliferation. Although the total DNA level increased, the RNA/DNA ratio was gradually decreased after NNNMU treatment. Seven days after NNNMU treatment the RNA/DNA ratio returned to the normal control level. During the acute alveolar injury, phospholipid and surfactant associated proteins were reduced significantly as compared with the control, implying that the secretory activity of alveolar type II cells was altered during acute alveolar injury induced by NNNMU. The protein content in crude surfactant during peak injury(7 days after NNNMU) was decreased significantly but phospholipid/protein ratios were identical in both control and NNNMU treatment groups. SDS-PAGE of proteins in crude pulmonary surfactant showed a decrease in major surfactant associated protein(M.W. 38,000) during acute alveolar injury. The present study may suggest that while alveolar type H cells proliferate markedly, transcription of alveolar type ll cell gene was inhibited by an unknown mechanism such as DNA methylation induced by NNNMU. Such an inhibition of transcriptional activity is thought to be associated with the decreased secretory activity of alveolar type ll cells, which may lead to pulmonary atelectasis and edema during the acute alveolar injury.

The number of cases of extracorporeal membrane oxygenation (ECMO) has rapidly increased all over Korea since the introduction of peripheral cannulation catheters. However, the application of ECMO to children has been limited due to the shortage of pediatric equipment and difficulty in maintaining an ECMO system with peripheral cannulation. For this reason, there have been only few reports of pediatric ECMO in Korea, and most of them pertained to the veno-arterial type ECMO for supporting the cardiac system in postcardiotomy patients. We report here on the successfully performing veno-venous ECMO, with using a double lumen percutaneous catheter, in a child with acute respiratory distress syndrome.

Objectives : To examine whether cumulative chronic stress influences the immune status, and to verify the effect of social support on the relationship between these two dimensions in male manufacturing workers. Methods : A total of 39 workers were recruited for this study. A structured-questionnaire was used to assess general characteristics, job characteristics (work demand and decision latitude), psychosocial distress, and social support. The serum levels of CD4 and CD8 were measured as immune markers, and were collected between 8:00 and 10:00am in order to standardize the markers. Nonparametric statistics were used to estimate the differences between job characteristics and the immune markers. Results : General characteristics, and health-related behaviors, were not associated with CD4, CD8 or CD4/CD8. No relationships were found between job characteristics and the mean levels of immune reactivity. These results were consistent, even after controlling for social support. Social support failed to modify the relationship toward work demand, decision latitude or psychosocial distress to CD4, CD8, and CD4/CD8. Conclusion : Cumulative chronic life stress might not influence the immune status, and the effects of social support on the immune function under chronic stress, may not play a crucial role in modifying the relationships. This implication supports that the effect of stress on the immune function may be determined by the characteristics of that stress. further research should effectively considers the type, magnitude and timing of a stress event, and modifiable factors, such as personality traits, coping style, and hormone excretion levels, on the alteration of immune status.

The research was conducted to investigate the characteristics of lateral wheel path distributions (wandering) in different traffic lanes. The lateral wheel path distributions may affect pavement life and various distress types. The results presented that the normal distribution curve with symmetry was observed in the 2-lane and 3-lane roads. In the case of the 2-lane road (on one direction), the wanderings were 70-95cm, and 70-85cm for the 1st and 2nd lanes, respectively, while in the case of the 3-lane road (on one direction), 50-60cm, 65-85cm, and 80-95cm for the 1st, 2nd, and 3rd lanes, respectively. In addition, the 1st lane vehicles tended to pass on the right side to avoid the opposite side vehicles, while the outside lane vehicles tended to pass on the left side to avoid the walkway.

PURPOSES: This study is to develop the deduct value curves for the calculation of pavement condition index of asphalt airfield pavement. METHODS: To develop the deduct value curves of asphalt airfield pavement, panel rating was conducted to decide the pavement condition based on pavement distress type, severity, and density. RESULTS: Results show that standard deviation of deduct values by panel rating is increased at higher severity level and as damage density increases. The deduct value of alligator cracking show the highest. CONCLUSIONS: The deduct value curves based on panel rating could be used without existing problems which were occurred in Shahin's method.

A 4-year-old female Cocker spaniel was presented with respiratory distress and abdominal distension. Pleural effusion, ascites, hepatosplenomegaly, and superficial lymphadenopathy were observed and multicentric lymphoma was diagnosed by cytological examination. Immunophenotyping of lymph node and bone marrow using polymerase chain reaction for antigen receptor rearrangement identified a stage V lymphoma originating from T-cell. Despite of systemic chemotherapy using L-asparagenase, vincristine, cyclophoaphamide and prednisolone, neurologic deficits came out and progressed. Cerebrospinal fluid analysis revealed neoplastic lymphocytic pleocytosis indicating central nervous system involvement of lymphoma. The postmortem diagnosis was confirmed based on the histology and imunohistochemistry.
