In this study, we wished to examine structurally the relationships between team collaboration intention and members trust, sense of belonging, performance expectation. For this purpose, we collected data from 161 participants experiences collaborative behavior using survey by questionnaires, to confirm the influential relationships between these constructs due to relative literature reviews such as Knowledge Sharing and Team Collaboration. PLS modelling techniques to verify the hypotheses was performed. Empirical results show that members s trust, sense of belonging, performance expectation significantly influenced the team collaboration intention except of 3 hypotheses(members trust and similarity, familiarity and sense of belonging, sense of belonging and members trust). From these results, we reaffirmed that higher attributes such as the members s trust, sense of belonging, performance expectation, opportunistic behavior, similarity, familiarity, usefulness influence team collaboration intention.

목적: 불안정성 대퇴 전자간부 골절 치료에서 골절의 원위부를 외측 전위시켜 전내측 피질골을 중첩 시키는 방법으로 정복 후 치료 결과에 대해서 알아보고자 하였다. 대상 및 방법: 2011년 8월부터 2012년 8월까지 불안정성 대퇴 전자간부 골절로 진단 받고 감마-3 정을 이용하여 치료한 후 최소 1년 이상 추시가 가능하였던 20예를 대상으로 하였다. 방사선학적 평가는 수술 후 및 최종 추시의 방사선 검사를 통하여 NSA, TAD, Cleveland index, 지연 나사의 활강 정도, 골유합 시기를 측정하였다. 골절 정복의 정도는 Baumgaertner 기준 변형된 방법을 따라 양호(good), 적당(acceptable), 불량(poor)로 분류하였다. 결과: 대퇴 경간각은 수술 후 평균 140。였으며, 최종 추시상 평균 135。로 감소되었다. TAD는 평균 11.3 mm였으며, 지연 나사의 위치는 정중앙에 12예, 중앙 하부에 8예가 위치하였다. 최종 추시시 지연 나사 활강 거리는 평균 5.5 mm였다. 평균 골유합 기간은 3.7개월이었으며, 수술 직후 골절의 정복 상태는 양호 15예, 적당 5예로 전예에서 만족할만한 정복을 얻었다. 최종 추시상 정복 소실 및 지연 나사의 골두 관통(cut out) 등의 고정실패 및 다른 합병증은 발생하지 않았다. 결론: 불안정성 대퇴 전자간부 골절 치료에서 골절의 원위부를 외측 전위시키고, 전내측 피질골 근위부를 중첩(overlap) 시키고, 전후면상 외반 정복, 측면상 전방 전위 각형성 정복은 정복 소실 및 지연 나사의 골두 관통 등의 고정실패를 줄일 수 있는 방법이라고 사료된다. Purpose: The purpose of this article is to evaluate the result of treatment of unstable intertrochanteric fractures by lateralization of distal fragment and antero-medial cortex contact of the distal shaft piece. Materials and Methods: We conducted an analysis of 20 cases of unstable intertrochanteric fractures treated using a gamma-3 nail from August 2011 to August 2012 and followed up for more than one year. Using postoperative and last follow-up radiographs, we measured NSA, TAD, Cleveland index, sliding length of the lag screw, and union time. Adequacy of reduction was assessed by a modification in the criteria of Baumgaertner and classified as good, acceptable, or poor. Results: The mean NSA was 140。postoperative and 135。at last follow-up. The mean TAD was 11.3 mm. The position of the lag screw was in center-center in 12 cases, center-inferior in eight cases. The mean distance of lag screw sliding was 5.5 mm at last follow-up. The mean union time was 3.7 months. The state of reduction postoperatively was good in 15 cases, and acceptable in five cases. There was no failure of reduction, lag screw cut-out, or other complications at last follow-up. Conclusion: The reduction method for lateralization of distal fragment and antero-medial cortex contact of the distal shaft piece in an unstable intertrochanteric fracture is very useful for prevention of collapse of the fracture site, lag screw cut-out, and mechanical failure.

Este estudio trata de las tertulias literarias del siglo XVIII espanol tales como la Academia de Tripode, la Academia del Buen Gusto, la tertulia de la Fonda de San Sebastia..n y los salones de Olavide. Estudiamos sus historias,sus caracteri..sticas, sus participantes y sus influencias en la literatura y la sociedad de la e..poca ilustrada. Las tertulias estudiadas llevaron a cabo un papel importante en la sociedad espanola de entonces como la esfera pu..blica para crear y divulgar una opinio..n pu..blica, a pesar de que eran reuniones so..lo para los nobles e intelectuales. Lograron la reforma poe..tica de la segunda mitad del siglo gracias a las conversaciones y las discusiones entre los tradicionalistas del gusto barroco y los neocla..sicos en las tertulias desde la Academia de Tri..pode hasta la tertulia de la Fonda de San Sebasti..an pasando por la Academia del Buen Gusto.

Dentro del escaso margen temporal, la comicidad siempre transporta la misma trascendencia en las diversas modificaciones del teatro breve. No obstante, su caracter o su funcion evoluciona de acuerdo con el sentido del humor propio de cada epoca y sociedad, relacionado con la vision del mundo. En este trabajo examinamos la funcion estetica de la risa del teatro breve -la liberadora (o carnavalesca) y la moralizadora-, sobre todo en los entremeses cervantinos y los sainetes de Ramon de la Cruz. Como si de sendas caras de una misma moneda se tratase, solo es visible una de las dos caracteristicas mientras que la otra queda encubierta segun su momento historico. Asi, en el Barroco se destaco evidentemente la carnavalesca; quedando oculta, pero no relegada, la moralizadora. En el Neoclasicismo se dio el proceso inverso. Por supuesto, hay diferencias en el grado de carnavalizacion y moralizacion segun las epocas. En cuanto a las normas sociales, la primera las transgrede revelando lo que es la realidad y los seres humanos, pero la segunda las defiende ensenando lo que deberia ser.

Objectives: Obesity is an important cause of insulin resistance that leads to obese type 2 diabetes. Recently it has been found that obesity is associated with adipose tissue accumulation which causes systemic inflammation. In this study, we investigated effects of Inula helenium on the inflammation in high fat diet-induced insulin resistance mouse. Methods: Insulin resistance was induced in C57BL/6 male mice (19~21 g) on a 60% fat diet. Mice were divided into 3 groups (n=6) of normal, control and Inula helenium. After 12 weeks, body weight, FBS, oral glucose tolerance test (OGTT), serum level of insulin, epididymal fat pad, liver weight and the gene expression of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, interleukin (IL)-10 and cluster of differentiation (CD) 68 were measured. Also, adipose tissue macrophage was analyzed by fluorescence activated cell sorting. Results: Inula helenium significantly reduces oral glucose tolerance levels, insulin serum level and adipose tissue macrophage. Also Inula helenium increased IL-10 gene expression and decreased CD68 gene expression. Conclusions: These results show that Inula helenium has anti-insulin resistance and anti-inflammatory effects on a high fat diet-induced insulin resistance mouse model.

N/A Background/Aims: Tbis study was aimed to evaluate the clinical significance of the sphincter of Oddi manometry (SOM), cholescintigraphy, endoscopic sphincterotomy(EST), and cholecystectomy in patients complaining of recurrent biliary-type abdominal pain. Methods: 20 patients with recurrent biliary-type abdominal pain not explained by conventional diagnostic studies were sampled. All the patients with manometrically verified sphincter of Oddi dystunction(SOD) and some patients with normal or failed manometry underwent EST. Among those with normal or failed manometry laparoscopic cholecystectomy was performed to patients with acalcu)ous cholecystopathy(ACP) diagnosed by cholescintigraphy. Results: Of 26 sessions of SOM tried in all the 20 cases, 2l sessions in 17 cases were technically successful. Among those 17 patients, SOM was abnormal in 9 cases(6:sphincter of Oddi dyskinesia; 3:sphincter of Oddi stenosis). Four of five patients undergoing cholescintigraphy in patients with normal or t'ailed manometry were verified as ACP. The procedure-related pancreatitis occurred in 7/26 sessions after SOM and in 3/12 sessions after EST. In 1 case, a micro-perforation followed EST. All these patients with complications recovered uneventfully. Mean duration of fo]low-up was 13.5(range 7 -24) months. EST was of benefit to 7 of 9 patients with manometrically verified SOD and also to all 3 patients with normal or failed manometry undergoing EST. Laparoscopic cholecystectomy was of henefit to all 3 patients with ACP undergoing cholecystectomy. Conclusions: Extensive diagnostic procedures such as SOM and cholescintigraphy and proper therapy according to their results should be considered with patients complaining of recurrent biliary-type abdominal pain not explained by other conventional diagnostic studies.

N/A A strong association between Helicobacter pylori (H. pylori) and chronic active inflammation of the gastric antrum and duodenal ulceration has been recognized. Although various rnethods have been proposed to detect this microorganism, no unanimity exists among investigators concerning which method represents a gold standard. H. pylori producee urease that converts urea to ammonia which then raises the pH, therefore we have utilized an endoscopic spray technique using phenol red (pH indicator) in vivo to assess H. pylori infection itself and its distribution. 87 patients with dyspepsia were pre-medicated with ranitidine 150 mg p.o. 3 houre before endoscopy to maintain a gastric pH between 3-6. During endoscopy, 20 ml of a mixture containing 0.05% phenol red and 0.5% urea was sprayed over the antral mucosa using a spray catheter. It was defined as positivc if any area of the mucosa turned red within 3 min after spraying. Antral biopsies were taken from all patients. Biopsies were assessed in a blind fashion after H&E, Giemsa and Warthin-Starry silver stain. The phenol red positive patients were 54.0%, and diffuse pattern of positive staining was 85.1% and regional pattern was 14.9%. Diagnostic sensitivity and specificity of the endoscoic spray technique were 87.2%. and 85.0% respectively. In conclusion, the endoscopic phenol red spray technique may be one of the simple and useful screening tests for diagnosis of H. pylori infection and for dilineating its probahle pattern of distributionvn gastric mucosa in vivo, but this method seems not useful for confirmatory diagnosis of H. pylori infection and needs further study.

N/A Adenomatous polyps are known to be precursors for cancer, and identifying of persons with adenomatous polyps is practically important because these individuals should constitute a disproportionate percentage of persons destined to have colorectal cancer. There is enough reason to believe that regclar endoscopic screening of persons with adenomatous polyps and removal of these polyps can reduce the incidence of colorectal cancer. But hyperplastic colonic polyps are generally regarded as being of little or no clinical consequence. Recentlyl, however, controversy has not been settled down on the significance of distal colonic hyperplastic polyp as a marker for proximal colonic adenomatous polyp (s). To establish the prevalence of proximal neoplasms in subjects with or without hyperplastic polyps in distal colon and to determine whether the presence of hypcrplastic polyps in the distal colon could serve as a market for proximal synchronous adenomatous colonic polyps, we prospectively analyzed 895 consecutive subjects who were examined with colcnoscopy between March 1990 and October l992. 191 of 895 subjects (21.4%) had one or more colonic polyps. The prevalence of adenomatous polyps alone was 10.2% hyperplastic polyps 8.4%, and both 1.9%. The proportion of subjects with both proximal adenomatous polyp and distal hyperplastic polyps (6.0%) was not significantly different from the proportion of those without distal hyperplistic polyps(5.1%), But subjects with distal adenomatous polyps (s) were si!nificantly more likely to have proximal adenomatous polyp (s) than those without distal adenomatous polyp (s). The result of this study suggests that hyperplastir. polyps of distal colon do not serve as a marker for neoplastic polyps of proximai colon.
