A Framework for Analyzing Electronic Communication: Bales' Interaction Process Categories and a Community of Practice

This paper describes and evaluates a tool developed to analyze communication interaction of Newslib LISTSERV using Bales' Interaction Process Category. In this study, Microsoft ACCESS was used for managing data and SAS Enterprise Guide was used for performing the statistical analysis and representing their results. The purpose of analyzing Newslib LISTSERV is to determine if there is evidence that this LISTSERV helps to create and reinforce a "community of practice" among the special librarians who work in a variety of News organizations. The results show that this group behaves as a community of practice by interchanging information or knowledge actively in their domains. The ACCESS relational database system is suitable for this study to organize and manipulate data because the relationship between entities needs to be modeled. The SAS Enterprise Guide is very useful to perform statistical analysis and represent results with new features such as the GUI interface and automatic output delivery system

How Learner-Centered Teaching is associated with Teacher Self-Efficacy and Job Satisfaction: Analysis of Data from 31 Countries

The expansion of learner-centered teaching has been the focus of education policy makers and teachers throughout the world. While most of the attention has been given to how learner-centered teaching influences student outcomes, it is important to consider how teachers are associated with learner-centered teaching. Using data from the OECD TALIS database, this study analyzes how the use of learner-centered teaching is associated with teacher self-efficacy and job satisfaction. Controlling for a wide range of teacher and classroom characteristics, as well as country and school fixed effects, we find that learner-centered teaching has a significant and positive association with both teacher self-efficacy and job satisfaction

Contemporary approaches to depression

Depression is one of the most important psychiatric disorders. It does not only affect the patients themselves but also influences their family members, friends, and society as a whole. The primary purpose of this paper is to discuss the general characteristics of depression in terms of the explanations provided by four major theoretical approaches. First, the biological approach considers the contributions to depression arising from distinct neural systems and their associated neurotransmitters. Second, the behavioral approach emphasizes learning processes, such as reinforcement and helplessness as causal to depressive behaviors. Third, the cognitive approach focuses on the causal role of distinctive patterns of cognition possessed by depressed patients. Finally, the sociological perspective considers the contributions arising from general forces within society, such as unemployment, social status, sex, and age. All of these approaches are very useful for understanding depression. However, depression is too complex to be fully explained by a single theory or two. It is necessary to integrate all the different approaches to understand and treat the illness in a better way

Effects of Aromatherapy on Stress, Sleep, Nausea and Vomiting during Patient Controlled Analgesia Treatment of Patients with Hysterectomy

PURPOSE: The purpose of study was to examine effects of aromatherapy on stress, sleep, nausea and vomiting of women after laparoscopic hysterectomy. METHODS: The participants were 60 women who had laparoscopic hysterectomy: experiment group for aromatherapy (n=30) and control group for routine care (n=30). The experimental group received inhalation aromatherapy for 5 minutes, twice; the first was done right after the operation, the second was at 9 pm before sleep on the same day--while the control group had no inhalation. Data were collected from July to September, 2012 at G hospital. RESULTS: The degree of psychological stress was not significantly different between two groups (t=-1.96, p= .054). Yet, there were significant differences between two groups for degree of physiological stress (t=-3.20, p= .002), the level of cortisol (t=-2.01, p= .049), the score of sleep status (t=2.47, p= .016), the score of sleep satisfaction (t=2.43, p= .018), and the score for nausea and vomiting (t=-2.58, p= .012). CONCLUSION: Inhalation aromatherapy using the mixed oil of lavender, mandarin, and marjoram was effective in decreasing the level of physiological stress, cortisol, and the score for nausea and vomiting, and also allowed the participants to have a better sleep. Therefore, inhalation aromatherapy could be effective in improving the quality of life of these women during recovery

The Impact of Project-Based Learning on Teacher Self-Efficacy

The expansion of project-based learning has been advocated for as a solution and reform measure to the problem of rote learning-based teaching practices in Korean schools, deemed unfit for the development of diverse skills needed in the 21st century. While the ultimate goal of initiating project-based learning is to affect students in positive ways, it is important to analyze how conducting project-based learning affects teachers, as they are the direct implementers of teaching practices and are bound to have immense influence on the overall learning experience of students. By using the OECD TALIS database, we show that conducting project-based learning is strongly and positively associated with teacher self efficacy. Such results are in line with an analysis using data obtained from a field experiment on teacher training of project-based learning conducted on Daegu city middle schools

Computed tomographic characteristics of acute thoracolumbar intervertebral disc disease in dogs

Forty canine patients with a presumptive diagnosis of the intervertebral disc herniation at the thoracolumbar region were imaged. A neurological examination was performed and all patients were classified under four grades by the examination. The degrees of attenuation of the herniated disc material were measured in Housefield units (HU) in each image. The ratio of the area to herniated disc material and the height to disc material were measured. The clinical grade was correlated with the area ratio of the herniated disc material to the spinal cord, but not correlated with the height ratio of that. In the patients with epidural hemorrhage at surgery, HUs of the herniated disc material was lower than those with no epidural hemorrhage at surgery. Non-contrast computed tomography scans of the spine can be useful in diagnosing acute intervertebral disc disease in chondrodystrophoid breeds, evaluating patient status and identifying concurrent epidural hemorrhage

Three-dimensional CT angiography of the canine hepatic vasculature

Eight Beagle dogs were anesthetized and were imaged using a single channel helical CT scanner. The contrast medium used in this study was iohexol (300 mg I/ml) and doses were 0.5 ml/kg for a cine scan, 3 ml/kg for an enhanced scan. The flow rate for contrast material administration was 2 ml/sec for all scans. This study was divided into three steps, with unenhanced, cine and enhanced scans. The enhanced scan was subdivided into the arterial phase and the venous phase. All of the enhanced scans were reconstructed in 1 mm intervals and the scans were interpreted by the use of reformatted images, a cross sectional histogram, maximum intensity projection and shaded surface display. For the cine scans, optimal times were a 9-sec delay time post IV injection in the arterial phase, and an 18-sec delay time post IV injection in the venous phase. A nine-sec delay time was acceptable for the imaging of the canine hepatic arteries by CT angiography. After completion of arterial phase scanning, venous structures of the liver were well visualized as seen on the venous phase

Osteochondrodysplasia in three Scottish Fold cats

This report explains typical radiographic features of Scottish Fold osteochondrodysplasia. Three Scottish Fold cats suffering from lameness were referred to the Veterinary Medical Teaching Hospital, Seoul National University, Korea. Based on the breed predisposition, history, clinical signs, physical examination, and radiographic findings, Scottish Fold osteochondrodysplasia was confirmed in three cases. Radiographic changes mainly included exostosis and secondary arthritis around affected joint lesions, and defective conformation in the phalanges and caudal vertebrae. The oral chondroprotective agents such as glucosamine and chondroitin sulfate make the patients alleviate their pain without adverse effects

Computed tomographic evaluation of abdominal fat in minipigs

Computed tomography (CT) exams were conducted to determine the distribution of abdominal fat identified based on the CT number measured in Hounsfield Units (HU) and to measure the volume of the abdominal visceral and subcutaneous fat in minipigs. The relationship between the CT-based fat volumes of several vertebral levels and the entire abdomen and anthropometric data including the sagittal abdominal diameter and waist circumference were evaluated. Moreover, the total fat volumes at the T11, T13, L3, and L5 levels were compared with the total fat volume of the entire abdomen to define the landmark of abdominal fat distribution. Using a single-detector CT, six 6-month-old male minipigs were scanned under general anesthesia. Three radiologists then assessed the HU value of visceral and subcutaneous abdominal fat by drawing the region of interest manually at the T11, T13, L1, L3, and L5 levels. The CT number and abdominal fat determined in this way by the three radiologists was found to be correlated (intra-class coefficient = 0.9). The overall HU ranges for the visceral and subcutaneous fat depots were -147.47 to -83.46 and -131.62 to -90.97, respectively. The total fat volume of the entire abdomen was highly correlated with the volume of abdominal fat at the T13 level (r = 0.97, p < 0.0001). These findings demonstrate that the volume of abdominal adipose tissue measured at the T13 level using CT is a strong and reliable predictor of total abdominal adipose volume
