To provide a systematic understanding of creativity among the factors affecting Innovation, this paper aimed to develop a measurement tool that classified creativity at an individual, group, and organizational level and created a measurement index for each level (influence factor), to present a model that verified the mediating effect of self-efficacy as a situational factor. As previous studies on creativity mainly focused on individual characteristics, tests of effects on organizational innovation have not been conducted and objective measurement tools that address other characteristics in addition to individual characteristics are limited. Accordingly, the present study aims to provide researchers and management consultants, who focus on organizational creativity, with a research framework by dividing creativity into three levels—individual creativity, creativity in groups, and creativity in organizations—and then, by developing metrics for each level, to present a model that identifies the causal relationships of innovation.

Background/Aims: Endoscopic ultrasound-guided fine needle aspiration and/or biopsy (EUS-FNA/B) have been used to diagnose subepithelial tumors (SETs) and extraluminal lesions in the gastrointestinal tract. Our group previously reported the usefulness of EUS-FNA/B for rectal and perirectal lesions. This study reports our expanded experience with EUS-FNA/B for rectal and perirectal lesions in terms of diagnostic accuracy and safety. We also included our new experience with EUS-FNB using the recently introduced ProCore needle. Methods: From April 2009 to March 2014, EUS-FNA/B for rectal and perirectal lesions was performed in 30 consecutive patients. We evaluated EUS-FNA/B performance by comparing histological diagnoses with final results. We also investigated factors affecting diagnostic accuracy. Results: Among 10 patients with SETs, EUS-FNA/B specimen results revealed a gastrointestinal stromal tumor in 4 patients and malignant lymphoma in 1 patient. The diagnostic accuracy of EUS-FNA/B was 50% for SETs (5/10). Among 20 patients with non-SET lesions, 8 patients were diagnosed with malignant disease and 7 were diagnosed with benign disease based on both EUS-FNA/B and the final results. The diagnostic accuracy of EUS-FNA/B for non-SET lesions was 75% (15/20). The size of lesions was the only factor related to diagnostic accuracy (P=0.027). Two complications of mild fever and asymptomatic pneumoperitoneum occurred after EUS-FNA/B. Conclusions: The overall diagnostic accuracy of EUS-FNA/B for rectal and perirectal lesions was 67% (20/30). EUS-FNA/B is a clinically useful method for cytological and histological diagnoses of rectal and perirectal lesions. (Intest Res 2015;13:135-144)
Primary malignant melanoma (MM) accounts for 1% of all cancers, and only 3% to 7% of these tumors occur in the female genital tract. Data are limited with respect to the basis for treatment recommendations because of the rarity of MM. The overall prognosis of melanomas of the female genital tract is very poor. Two cases of MM of the female genital tract are presented. The first case is of a 70-year-old female patient who complained of left thigh pain and underwent magnetic resonance imaging that showed cervical cancer with involvement of the vagina, bladder, and parametrium, in addition to multiple bony metastases of the proximal femur, acetabulum, and both iliac bones. The second case is of a 35-year-old female patient who suffered from vaginal bleeding for 5 months, and she was diagnosed as having primary vaginal melanoma. The patient underwent radical surgery and two additional surgeries because of recurrence of cancer in both inguinal areas. After surgery, the patient received adjuvant immunotherapy, radiation therapy, and chemotherapy. In both the aforementioned cases, the pathologic diagnosis was made after immunohistochemical analysis, i.e., the tumor cells were stained with HMB-45 and S100, and were found to be positive for both immunostains.
We developed a minimally-invasive canine model of spinal cord injury (SCI). A balloon catheter was inserted into the epidural space via the lumbosacral space, and inflated between L2 and L3 for 30 or 60 minutesunder fluoroscopic guidance. Motor function after SCI was assessed using modified Tarlov scale. All seven dogs showed complete paraplegia after the procedure, neurological problems were evident and the modified Tarlov scores remained at zero after the SCI procedure; no improvement in clinical signs was observed. The dogs underwent 3T MR imaging at 3 days and 1 year after SCI. Histopathologic examinations were conducted at 2 weeks, 12 weeks and 1 year after SCI. Two pig also underwent 60-minute compression, These pigs underwent 3T MR imaging at 3 days. The pigs also showed paraplegia for 1 week. In the present study, we described an animal model of minimally invasive spinal cord injury using a balloon catheter without laminectomy under fluoroscopic guidance. And, this percutaneous spinal cord compression injury model has many potential applications.

Type 1 diabetes is a common metabolic disorder accompanied by increased blood glucose levels along with glucocorticoid and cognitive deficits. The disease is also thought to be associated with environmental changes in brain and constantly induces oxidative stress in patients. Therefore, glucocorticoid-mediated negative feedback mechanisms involving the glucocorticoid receptor (GR) binding site are very important to understand the development of this disease. Many researchers have used streptozotocin (STZ)-treated diabetic animals to study changes in GR expression in the brain. However, few scientists have evaluated the hyperglycemic period following STZ exposure. In the present study, we found GR expression in the hippocampus varied based on the period after STZ administration for up to 4 weeks. We performed immunohistochemistry and Western blotting to validate the sequential alterations of GR expression in the hippocampus of STZ-treated type 1 diabetic rats. GR protein expression increased significantly until week 3 but decreased at week 4 following STZ administration. GR expression after 70 mg/kg STZ administration was highest at 3 weeks post-treatment and decreased thereafter. Although STZ-induced increase in GR expression in diabetic animals has been described, our data indicate that researchers should consider the sequential GR expression changes during the hyperglycemic period following STZ exposure.
The right ventricle is composed of 3 distinct portions: the smooth muscular inflow (body), the outflow region, and the trabecular apical region. Volumetric quantification of RV function is challenging because of the many assumptions required Evaluation of RV structure and function in patients with cardiopulmonary disorders is an essential component of clinical management. RV segments should be comprehended as basic knowledge and echocardiographic views should be gotten skillfully for evaluation of those. Apical 4-chamber, modified apical 4-chamber, left parasternal long-axis (PLAX) and parasternal short-axis (PSAX), left parasternal RV inflow, and subcostal views provide images for the comprehensive assessment of RV systolic and diastolic function and RV systolic pressure (RVSP) Echocardiography is a readily available and reliable noninvasive imaging modality to detect changes in RV size and systolic function. Causes of RV dilation and/or dysfunction contain pressure overload, volume overload and intrinsic pathology. As cause of abnormality in RV equality, systolic or diastolic function, pulmonary embolism, pulmonary hypertension, tricuspid valve regurgitation, RV infarction and cardiomyopathies, etc should be considered. Also, for diagnosing echocardiography for pulmonary embolism, Acute cor pulmonale, chronic cor pulmonale and normal state have to be distinguished. It is very important to figure out echocardiographic finding of acute cor pulmonale because the most common cause of acute cor pulmonale is a pulmonary embolism. Echocardiography is frequently obtained in patients with symptoms suggestive of acute pulmonary embolism. A thorough understanding of the echocardiographic findings in acute pulmonary embolism may be useful in expediting recognition and management of these patients. One of the most significant in echocardiography for pulmonary embolism is as following: 1) RV equality, 2) RVOT systolic excursion, RV mid ventricular strain, 3) RV Doppler parameter (MPI, especially). Recently, RVOT systolic excursion has been the focus of suspecting acute pulmonary embolism.
