The objective of this study was to investigate the managing realities of EVD and provide a descriptive survey with the attempt to obtain basic data needed for the standardization of EVD management. For that purpose, 220 questionnaire copies were distributed to those nurses who were working with intensive care units at university hospitals, general hospitals, semi-general hospitals in Seoul, Kyongki-de and local areas. Of 158 returned questionnaire copies, 139 were used for analysis. Data were collected during the term of academic seminars of Neurosurgery Nursing Committee and KICA (Korea Intensive Care Association), ranging from Oct. 26 through 27. 2000. The tools utilized a structured questionnaire form consisting of 21 questions on general characteristics, the level of understanding, the level of work performance, standard management guidelines, etc. The data collected were analysed with frequency, percentage, mean vague, chi -square test using the SPSS 10.0 program Findings were revealed, as follows: For managing the prevention of EVD infection, aseptic technique was found to be of the most importance (48.9%),'the technique should be carried out at an operation room'(92.8%), but it was actually performed at intensive care units (over 51.5%). 'The term of antibiotics use should be less than 7 days' (81.8%), while it was actually executed for less than 7 days (49.5%). 'The proper time of quittance from it should be within less than 7 days'(74.1%) but actual quittance was executed only by 51.1%. 'Set exchange is needed' by 54.0% but actual exchange was implemented merely by 28.1%. 'The subject of management should be nurses' was reflected by 40% but actually 52.0% were carried out. As a result of hating analysed the understanding of the management of EVD by general characteristics, a significant difference was found in the necessity for set exchange by hospitals, in the time of quittance of a catheter, and in ablution items by work experience. The result of hating analysed the work performance levels of EVD management by general characteristics revealed that a significant difference in administration facilities of medicine by the classification of hospitals, especially the use of antibiotics and the quitting time of a catheter by the classification of intensive care units, and in the use of antibiotics and ablution items by the standard management guidelines.

The purpose of this study is to investigate the correlation among the stroke patient family's upon the oomparative appreciation of the adult stroke patient's family and elderly stroke patient's family For this purpose, data were collected from the family care-givers for two groups of stroke Patients under sixty years old and over sixty years of age, admitted at K Hospital and H Hospital in Seoul. The instruments for this research are based on the tool for measuring physital health and Young-hee(1992), the tool fort measuring the sense of burden by S대, Mee-hae and Oh, Ga-sil(1993), and the tool for the quality of life by Noh, Yoo-ja(1988). The sampling for this study was done from December, 2000 until February, 2001. Questionnaire data were drawn up by personal interviews added by the staff nurses. The analysis of collected data are based on general characteristics calculated at the rate of 100 percent of the average, t-test, ANOVA(some difference on a level with p<.05 being subsquently confirmed by DMR) for Health Status, Burden, Quality of Life and Pearson Corretation to verify the hypothetical correlation among the subjects. The results of this study are as follows: 1. In the adult stroke patient family, the factors influencing the physical health proved to be age, present occupation and family-formation. Here, the factors influencing psychological health turned out to be age, matrimonial status, present occupation and family-formation. In the elderly stroke patient family, the factors influencing physical health proved to be age, gender, final academic status, matrimonial status, present occupation, and relation with the patient. Here, the factors influencing the psychological health were age, final academic status, matrimonial status, present occupation, relation with the patient and family-formation. In the former case, the influencing factors upon the burden were matrimonial status, relation with the patient and family-formation. In the latter case, the influences upon the burden were age, gender, final academic status, matrimonial status, present occupation and relation with the patient. In the former case, the influences on the quality of life were gender, and economic situation. In the later case, the influencing factors on the quality of life were age, final academic status, matrimonial status, present occupation, and relation with the patient. 2. The rate of the physical condition in the former case turned out to be 2.83, and the psychological condition 2.37. The physical condition of the latter case was 2.76, and the psychological condition 2.46. The rate of the burden in the former case was 3.14, and that of the latter case was 3.04. The rate of quality of life in the former case proved to be 2.46, and that of the latter case 2.55. 4. The rate of correlation between the burden and the Quality of life appealed to be the of correlation between the psychological health and the burden of a similar (r= -.565). The rate of correlation between the physical health and the psychological health proved to be a moderate correlation (r= .372). The rate of correlation between physical health and the burden turned out to be a low counter-correlation (r= -.276). According to this study, there proved to be a very close correlation the stroke Patient family's health, the burden and quality of life. Thus, it would be necessary to find out various nursing interventions in order to mitigate the stroke patient family's burden in the process of caring for the patients.

<P>Synthesis of long-chain branched polymers has been a crucial concern in the polyolefin industry. In this study, a method to produce long-chain branches (LCBs) in coordinative chain transfer copolymerization (CCTcoP) is suggested. A dialkylzinc compound bearing vinyl groups ((9-decenyl)<SUB>2</SUB>Zn) is prepared, which works well not only as a chain transfer agent but also as a comonomer in CCTcoP, resulting in the generation of LCBs. The generation of LCBs is confirmed by gel permeation chromatography studies and through the analysis of rheology data. The formation of LCBs by connecting the two growing polyolefin chains can facilitate the generation of polymers with molecular weights higher than that expected. Owing to the presence of LCBs, considerable shear thinning behavior is observed. Ethylene/1-octene copolymers can be prepared facilely to show almost the same shear thinning behavior with the commercial grade of low-density polyethylene, which is known to have a substantial amount of LCBs.</P> [FIG OMISSION]</BR>

Lee, Su Hyun,Moon, Woo Kyung,Cho, Nariya,Chang, Jung Min,Moon, Hyeong-Gon,Han, Wonshik,Noh, Dong-Young,Lee, Jung Chan,Kim, Hee Chan,Lee, Kyoung-Bun,Park, In-Ae by Lippincott Williams Wilkins 2014 Vol. No.

OBJECTIVE: The objective of this study was to compare the quantitative and qualitative shear-wave elastographic (SWE) features of breast cancers with mechanical elasticity and histopathologic characteristics. MATERIALS AND METHODS: This prospective study was conducted with institutional review board approval, and written informed consent was obtained. Shear-wave elastography was performed for 30 invasive breast cancers in 30 women before surgery. The mechanical elasticity of a fresh breast tissue section, correlated with the ultrasound image, was measured using an indentation system. Quantitative (maximum, mean, minimum, and standard deviation of elasticity in kilopascals) and qualitative (color heterogeneity and presence of signal void areas in the mass) SWE features were compared with mechanical elasticity and histopathologic characteristics using the Pearson correlation coefficient and the Wilcoxon signed rank test. RESULTS: Maximum SWE values showed a moderate correlation with maximum mechanical elasticity (r = 0.530, P = 0.003). There were no significant differences between SWE values and mechanical elasticity in histologic grade I or II cancers (P = 0.268). However, SWE values were significantly higher than mechanical elasticity in histologic grade III cancers (P < 0.001), which have low amounts of fibrosis, high tumor cellularity, and intratumoral necrosis. In addition, color heterogeneity was correlated with intratumoral heterogeneity of mechanical elasticity (r = 0.469, P = 0.009). Signal void areas in the masses were present in 43% of breast cancers (13 of 30) and were correlated with dense collagen depositions (n = 11) or intratumoral necrosis (n = 2). CONCLUSIONS: Quantitative and qualitative SWE features reflect both the mechanical elasticity and histopathologic characteristics of breast cancers.

Lee Min Wan,박성실,You Kiho,Lee Dong-eun,Lee Dong Woon,Park Sung-Chan,Han Kyung Su,Sohn Dae Kyung,Hong Chang Won,Kim Bun,Kim Byung Chang,Chang Hee Jin,김대용,오재환 대한대장항문학회 2024 Annals of Coloproctolgy Vol.40 No.1

Purpose: This study aimed to evaluate the long-term clinical outcomes based on the ligation level of the inferior mesenteric artery (IMA) in patients with rectal cancer.Methods: This was a retrospective analysis of a prospectively collected database that included all patients who underwent elective low anterior resection for rectal cancer between January 2013 and December 2019. The clinical outcomes included oncological outcomes, postoperative complications, and functional outcomes. The oncological outcomes included overall survival (OS) and relapse-free survival (RFS). The functional outcomes, including defecatory and urogenital functions, were analyzed using the Fecal Incontinence Severity Index, International Prostate Symptom Score, and International Index of Erectile Function questionnaires.Results: In total, 545 patients were included in the analysis. Of these, 244 patients underwent high ligation (HL), whereas 301 underwent low ligation (LL). The tumor size was larger in the HL group than in the LL group. The number of harvested lymph nodes (LNs) was higher in the HL group than in the LL group. There were no significant differences in complication rates and recurrence patterns between the groups. There were no significant differences in 5-year RFS and OS between the groups. Cox regression analysis revealed that the ligation level (HL vs. LL) was not a significant risk factor for oncological outcomes. Regarding functional outcomes, the LL group showed a significant recovery in defecatory function 1 year postoperatively compared with the HL group.Conclusion: LL with LNs dissection around the root of the IMA might not affect the oncologic outcomes comparing to HL; however, it has minimal benefit for defecatory function.

Objective: The aim of this study was to prospectively evaluate whether liver stiffness (LS) assessments, obtained by twodimensional (2D)-shear wave elastography (SWE) with a propagation map, can evaluate liver fibrosis stage using histopathology as the reference standard. Materials and Methods: We prospectively enrolled 123 patients who had undergone percutaneous liver biopsy from two tertiary referral hospitals. All patients underwent 2D-SWE examination prior to biopsy, and LS values (kilopascal [kPa]) were obtained. On histopathologic examination, fibrosis stage (F0–F4) and necroinflammatory activity grade (A0–A4) were assessed. Multivariate linear regression analysis was performed to determine the significant factors affecting the LS value. The diagnostic performance of the LS value for staging fibrosis was assessed using receiver operating characteristic (ROC) analysis, and the optimal cut-off value was determined by the Youden index. Results: Reliable measurements of LS values were obtained in 114 patients (92.7%, 114/123). LS values obtained from 2D-SWE with the propagation map positively correlated with the progression of liver fibrosis reported from histopathology (p < 0.001). According to the multivariate linear regression analysis, fibrosis stage was the only factor significantly associated with LS (p < 0.001). The area under the ROC curve of LS from 2D-SWE with the propagation map was 0.773, 0.865, 0.946, and 0.950 for detecting F ≥ 1, F ≥ 2, F ≥ 3, and F = 4, respectively. The optimal cut-off LS values were 5.4, 7.8, 9.4, and 12.2 kPa for F ≥ 1, F ≥ 2, F ≥ 3, and F = 4, respectively. The corresponding sensitivity and specificity of the LS value for detecting cirrhosis were 90.9% and 88.4%, respectively. Conclusion: The LS value obtained from 2D-SWE with a propagation map provides excellent diagnostic performance in evaluating liver fibrosis stage, determined by histopathology.
