Background: Insertion of a ProSealTM laryngeal mask airway (PLMATM) by experienced users was more successful with using a catheter-guided (CG) technique than a digital technique. The purpose of this study is to assess the efficacy of the CG insertion technique for a PLMATM by inexperienced personnel. Methods: Forty patients aged 18−65 yr and who were undergoing general anesthesia were randomly allocated to the index finger (IF) or CG insertion techniques for PLMATM insertion. The IF technique was performed with the routine insertion technique. The CG technique was performed using a catheter inserted PLMATM, which was primed into the drain tube of the PLMATM with using a soft flexible catheter. Successful insertion was primarily judged by the clinical function of the airway. The number of insertion attempts and the insertion time were recorded. Postoperative airway morbidity (sore throat, dysphonia, dysphagia) was assessed at 24 hr postoperatively. Results: The success rate was similar between the groups (IF, 18/20; CG, 15/20). The successful insertion time (the time to provide an effective airway) was similar between the groups but the insertion time at the first attempt was shorter for the IF technique (IF, 21.6 ± 5.3 s; CG, 27.4 ± 10.3 s). There were no differences between the groups for the postoperative airway morbidity. Conclusions: This study suggests that the CG insertion technique is not a useful alternative technique for inexperienced personnel.

The POE (Post Occupancy Evaluation) was carried out to provide basic behavioral knowledge for its planning and management of the Rose garden at Yong-In Farmland. Through its users a total of 1545 questionnaire were completed. They were designed by four sets of variables, such as behavoir pattern, motivation for visting, post-use evaluation, and users demographic variables. The findings are as follows: Firstly, descriptive statistics were employed to analyze behavoir pattems and users' demographic varialbes. As a result, 86% of visitors lived in Kyoung-Ki Do and Seoul : most of the vistiors is in their twenties and thirties : most of visitors were accompanied by their families, relatives and lovers : 66% of vistiors came by cars to Yong-In Farmland : 47% of visitors stayed for 1-2 hours in average. Secondly, factor analysis was used in order to group satisfaction factors. Five factors are : 'manegement of the garden', 'rose appearance', 'design and aesthetics', 'lighting and sound', and 'theme display'. Thirdly, regression analysis was used to examine the sources of satisfaction. The results of regression analysis shows that 42% of total variances was explained by ten variables. The most effective variable is 'the aspect of rose condition and appearance'. The overall evaluation for the new rose garden was 'satisfied' though the level of the 'satisfied' varies according to their ages. Twenties and thirties prefer that image of fantastic European style which was frequently showed on T.V or movies. Forties and fifties like more abudant scenery of roses of an Europenan style garden but unsatisfied with shortage of roses.

The advent of the internet has caused a number of changes in production and dissemination of science and technology information(STI). STI was mainly produced in the form of publication before the advent of the internet. The popularization of the internet, however, has induced the mass production and distribution of STI through the internet. In consequence, the importance and usefulness of on-line STI have become on a level with those of published STI. The rapid growth of quantity and quality of on-line STI forces information service organizations try their best for improving the service satisfaction. In an effort to improve the satisfaction, researchers on information management examined the classification of information resources by exploring the counterparts of bibliography and/or web information service. We examined the national standard of the classification related to science and technology and proposed a practical scheme for the classification of on-line STI resources.

It depends on the joint configuration, dimensions and constraints of the joint whether the residual stress at the root of single-sided butt weld is tensile or not. Therefore, recommendation is generally made that high R ratio should be used in the fatigue test of welded joint in order to prevent excessively long life caused by compressive residual stress. In this research, the residual stress profile in butt weld joint was obtained through compliance method, using successive extension of a slot and measurement of the variation of strain during the slot extension. The residual stress profile was firstly assumed to be the linear summation of Legendre polynomials up to 9th order excluding 0th and 1st order. Strain variation on the surface was measured while the slot was being extended by cutting to find out the 8 unknown coefficients of each polynomial term. The cut was made by the electric discharge machine. It was concluded that the residual stress near the surface is positive valued, however, it turned into the negative value as soon as it passed through 2 or 3 mm of the depth.

Pyramid type three roll bending machines are widely used in roll-bending process to produce singly curved plate. In forming singly curved plate, controlling the vertical displacement of the center roller is most important to acquire the shape required and automation system of the process. In this paper roller bending process is modeled as an elastic-plastic phenomenon and analyzed using beam theory and finite element method. In finite element analysis the workpiece is modeled by using beam elements and plane strain elements respectively. Through the analyses vertical center roller displacement is obtained to get constant curvature distribution along arc length. The relationship between center roller displacement and curvature in steady state as well as residual stress and strain along plate thickness direction are calculated through finite element analysis.

Herpes zoster is a varicella-zoster virus reactivation that is characterized by pain and rash. It can cause motor paresis on affecting muscles, but diaphragmatic paralysis is a rare com- plication. Methods of evaluation of diaphragmatic paralysis include plain radiography, fluoroscopy and electroneurography. The direct movement of diaphragmatic muscles on ultrasound can also be used to diagnose diaphragmatic paralysis. We reported a case of a 72-year-old woman who developed left hemidiaphragmatic para- lysis after herpes zoster. The diaphragmatic paralysis occurred 3 weeks after appearance of a typical skin rash on the left C4-5 dermatomes. We diagnosed diaphragmatic paralysis using ultra- sound.

Background: Postoperative nausea and vomiting (PONV) are common complications after anesthesia and surgery. This study was designed to compare the effects of palonosetron and ondansetron in preventing PONV in high-risk patients receiving intravenous opioid-based patient-controlled analgesia (IV-PCA) after gynecological laparoscopic surgery. Methods: One hundred non-smoking female patients scheduled for gynecological laparoscopic surgery were randomly assigned into the palonosetron group (n = 50) or the ondansetron group (n = 50). Palonosetron 0.075 mg was injected as a bolus in the palonosetron group. Ondansetron 8 mg was injected as a bolus and 16 mg was added to the IV-PCA in the ondansetron group. The incidences of nausea, vomiting and side effects was recorded at 2 h, 24 h, 48 h and 72 h, postoperatively. Results: There were no significant differences between the groups in the incidence of PONV during 72 h after operation. However, the incidence of vomiting was lower in the palonosetron group than in the ondansetron group (18% vs. 4%, P = 0.025). No differences were observed in use of antiemetics and the side effects between the groups. Conclusions: The effects of palonosetron and ondansetron in preventing PONV were similar in high-risk patients undergoing gynecological laparoscopic surgery and receiving opioid-based IV-PCA.

김유일,조은윤,박하영,조준훈,한정호 대한병리학회 2013 Journal of Pathology and Translational Medicine Vol.47 No.2

Congenital peribronchial myofibroblastic tumor (CPMT) is a benign pulmonary spindle cell neoplasm of intrauterine and perinatal period, which is thought to arise from primitive peribronchial mesenchyme. We present a case detected incidentally in a one-month-old infant. The solid and partially necrotic tumor involved the right middle and lower lobes of the lung with extension to the diaphragm. Histologically, the tumor was composed of fasciculated monotonous spindle cells, proliferating peribronchiolar cartilage and round cells with rich vasculature, and high mitotic activity was identified in the round cell area. Immunohistochemical and electron microscopic studies showed that the spindle cells were myofibroblastic in phenotype. Although the tumor showed several malignant pathological features, recurrence was not observed in the two-year follow-up period, consistent with the benign clinical behavior of CPMT.
