Objectives : Eye movement desensitization and reprocessing(EMDR) is a novel, time-limited psychotherapy originally developed for treatment of psychological trauma. The effectiveness of this therapy has been validated only for posttraumatic stress disorder ; however, EMDR is often applied to other psychiatric illnesses, including other anxiety disorders and depression. This pilot study tested the efficacy of EMDR added to the routine treatment for individuals with acute stage schizophrenia. Methods : This study was conducted in the acute psychiatric care unit of a university-affiliated training hospital. Inpatients diagnosed with schizophrenia were randomly assigned to either three sessions of EMDR, three sessions of progressive muscle relaxation(PMR) therapy, or only treatment as usual(TAU). All the participants received concurrent typical treatments(TAU), including psychotropic medication, individual supportive psychotherapy and group activities in the psychiatric ward. The Positive and Negative Syndrome Scale(PANSS), the Hamilton Depression Rating Scale and the Hamilton Anxiety Rating Scale were administered by a clinical psychologist who was blinded to the patients' group assignment. Results : Forty-five patients enrolled and forty patients(89%) completed the post-treatment evaluation. There were no between-group differences in the withdrawal rates of patients during the treatment or at the three-month follow-up session. All three groups improved significantly across each of the symptomatic domains including schizophrenia, anxiety, and depressive symptoms. However, a repeated measures ANOVA revealed no significant differences among the groups over time. Effect size for change in total PANSS scores was also similar across treatment conditions, but effect size for negative symptoms was large for EMDR(0.60 for EMDR, 0.39 for PMR and 0.21 for TAU only). Conclusion : These findings supported the use of EMDR in treating the acute stage of schizophrenia but the results failed to confirm the effectiveness of the treatment over the two control conditions in three sessions. Further studies with longer courses of treatment, more focused target dimensions of treatment, and a sample of outpatients are necessary.

In this study, we investigated the preservice elementary school teachers' self-images of science teaching and the factors influencing their formation by using Draw-A-Science-Teacher-Test Checklist (DASTT-C). One-hundred eighty-two sophomores and 183 seniors were selected from the departments of science and non-science education in three national universities of education. DASTT-C was administered to the sophomores at the beginning of the Spring Semester, and to the seniors at the beginning of the Fall Semester. Analyses of the results revealed that the self-images of science teaching of the seniors were more student-centered than those of the sophomores in the department of science education. However, there was no significant difference between the DASTT-C scores of the sophomores and the seniors in the department of non-science education. Many sophomores answered that the main factors affecting their self-images of science teaching were teaching-learning experiences in elementary, middle and high schools. However, many seniors cited the content and teaching methods in science education courses as well as direct or indirect teaching-learning experiences in teaching practices regardless of the departments. Educational implications of these findings are discussed.

As network and multimedia service has increased in educational environment, it is needed to study on digital system based educational scenarios, especially in art and design departments in which visual educational materials mainly used. Therefore, this study was conducted with three objectives: first, developing components of design database and their classification system, second, developing contents of database for fundamental form education in design, and third, developing application method of database. According to these objectives, the secondary research was implemented into two directions; the analysis of classification categories of design, and the analysis of contents and process of fundamental form design education. From the secondary research, it was found that design database should have a flexible structure with flexible components as well as fixed components to include subjective and aesthetic assessment. In the end, the application methods and user interface system of design database was developed based on design educational scenarios.

Purpose: Treatment and prognosis in patients with pelvic bone fracture depend on the characteristics of the fracture and the stability of the pelvic ring. The purpose of this study is to analyze the characteristics of and the relationships between fracture patterns, injury mechanisms, clinical courses, and prognoses according to the hemodynamic pattern. Methods: Between January 2004 and September 2006, 89 patients under diagnosis of pelvic bone fracture were retrospectively analyzed on the basis of medical records and radiologic examinations. Patients with confirmed hemorragic shock with a systolic pressure of less than 90 mmHg were defined as the shock group. Young's classification was used to characterize fracture patterns. Factors relating to the clinical manifestation and to treatments such as transfusion and surgery were analytically compared. Results: The mean age of the patients was $48.8{\pm}18.7$, among which 49 (55.1%) were male. The numbers of shock and non-shock patients were 35 (39.3%) and 54 (60.7%) respectively. Eighteen (51.4%) of the shock patient had injuries resulting from pedestrian accidents (p=0.008). According to Young's classification, lateral impact fractures amounted to 20 and 33, front-rear impact fractures to 9 and 20, and multiple fractures to 6 and 1 among the shock and non-shock patients, respectively (p=0.027). Thirty-nine (39) cases in non-shock injuries were conservatively managed while 18 cases in shock injuries were surgically treated. In the shock group, the liver and the kidney were often damaged, as well. Among the shock patients, the average admission period was $7.5{\pm}8.7days$ in intensive care and $55.1{\pm}47.9days$ in total, which were longer than the corresponding numbers of days for the non-shock patients (p<0.05). No deaths occurred in the non-shock group while 5 deaths (14.2%) occurred in the shock group (p=0.007). Conclusion: The factors affecting hemodynamic instability in patients with pelvic bone fracture are injury mechanism, classification of fracture, and associated injuries.

Purpose: The aims of this study were to evaluate the clinical manifestations and prognosis of the syndromic and nonsyndromic intrahepatic bile duct paucity (IHBDP). Methods: We studied histology of 42 infants with neonatal cholestasis. Fourteen patients were diagnosed as IHBDP. We evaluated the clinical manifestations, courses and prognosis retrospectively. Results: Underlying disease of the 42 infants with neonatal cholestasis were biliary atresia in 23, intrahepatic bile duct paucity in 14 (Alagille syndrome in 4 and nonsyndromic IHBDP in 10), neonatal hepatitis in 5 infants. The mean ratio of the bile ducts per portal tract was 0.087 (range: 0~0.5). The manifestations in 4 patients with Alagille syndrome demonstrated as follows: characteristic face in 3, chronic cholestasis in 4, posterior embryotoxon in 2, vertebral anomalies in 2, peripheral pulmonary stenosis in 2. One of 4 patients of Alagille syndrome improved cholestasis and the other 3 patients were remained their cholestasis and growth retardation. All patients of the nonsyndromic IHBDP were idiopathic. Seven out of 8 patients of nonsyndromic IHBDP showed improvement of cholestasis, and one patient received liver transplantation due to cirrhosis. Conclusion: This study suggested that IHBDP should be considered in the differential diagnosis of neonatal cholestasis. The outcome of idiopathic IHBDP was better than predicted.

Background: This study was performed to evaluate the incidence and clinical characteristics of symptomatic pneumothorax in the full-term neonate. Materials and Methods: We retrospectively reviewed the medical records of 32 symptomatic pneumothorax patients in the full term neonates who admitted to the neonatal intensive care unit in Ulsan Dong Kang General Hospital from January, 2000 to December, 2004. The subjects were divided into two groups according to underlying causes; spontaneous pneumothorax group and secondary pneumothorax group, then each clinical characteristics were assessed. Results: Spontaneous pneumothorax patients were 10(31%) and secondary pneumothorax patients were 22(69%). Overall incidence of spontaneous pneumothorax was 0.4%. Most common cause of secondary pneumothorax was pneumonia. Twelve cases(54.5%) among secondary pneumothorax patients were associated with mechanical ventilator care. Clinical characteristics, courses and managements were similar between two groups, but more shorter duration of admission and chest-tube insertion in spontaneous pneumothorax group Conclusion: The patient with symptomatic pneumothorax needs careful observation and proper management with or without underlying respiratory diseases.

Purpose: Carbamate insecticides are potent cholinesterase inhibitors capable of causing severe cholinergic toxicity. Use of carbamate rather than organophosphate insecticides has been increasing. Compared with organophosphate poisoning, relatively few studies have investigated carbamate-associated acute pancreatitis. We investigated general characteristics and pancreatitis of carbamate poisoning and the predictors, among those readily assessed in the emergency department. Methods: We performed a retrospective review of consecutive patients, aged over 18 years, who were admitted between January 2008 and April 2012 to an emergency department (ED) of an academic tertiary care center for treatment of carbamate poisoning. Patients who exhibited poisoning by any other material, except alcohol, were excluded. After application of exclusion criteria, patients were divided according to carbamate-induced pancreatitis and non-pancreatitis groups. Results: A total of 41 patients were included in this study. Among these 41 patients, the prevalence of acute pancreatitis was 36.6% (15 patients). Initial blood chemistry tests showed a statistically higher glucose level in the pancreatitis group, compared with the non-pancreatitis group (222, IQR 189-284 vs. 137, IQR 122-175 mg/dL, P<0.05). Regarding clinical courses and outcomes, a significantly higher proportion of patients developed pneumonia [10 (66.7%) vs. 6 (23.1%), P<0.05] and had a longer hospital stay (7 days, IQR 6-12 vs. 5 days, IQR 2-11, P<0.05), but no difference in mortality, in the pancreatitis group vs. the non-pancreatitis group. In multivariate analysis, the initial glucose was showing significant association with the presentation of carbamate-induced acute pancreatitis (odds ratio 1.018, 95% confidence interval 1.001-1.035, P<0.05). Conclusion: Carbamate-induced acute pancreatitis is common, but not fatal. Initial serum glucose level is associated with acute pancreatitis.

The purpose of this study is to analyze the previous research on geological fieldwork from 2000 to 2020, examine the tasks that have been focused on, and suggest directions and implications for future geological fieldwork research. The data was conducted for the thesis searched on ScienceON and RISS in relation to geological fieldwork and journals listed in the Korean Citation Index(KCI), and the study title was analyzed using the semantic network analysis. For analysis, the data that had been pre-processed was visualized as a network by semantic network analysis, and frequency and centrality were analyzed. The centrality analysis was based on degree centrality and eigenvector centrality, and all analyzes were performed by dividing the entire study period into four periods: 2000-2005, 2006-2010, 2011-2015, and 2016-2020. As a result, research on geological fieldwork focused more on the development of geological field courses, and in particular, jeju island was actively discussed as a learning site. Also, the study was conducted on students rather than teachers, and among them, high school students showed high frequency and centrality. In addition, it can be seen that studies on the educational effect of geological fieldwork were discussed, either in connection with programs such as STEAM, free-semester program, or indirect geological fieldwork methods such as web, flash panorama, and 3D. This study is meaningful in that it suggests the direction of future research by looking back on the research on geological fieldwork that has been done so far.

to apply standardized principles and methodologies to the appraisal of records because it is different for each country, region, and organization to distinguish what kind of records are important and how to select them. For this reason, numerous theories and methodologies have been proposed around the appraisal of records. ISO 15489-1:2016, on the other hand, has laid the groundwork for the standardization of the appraisal of records that are applicable globally in recent record management environments based on a new perspective on the appraisal of records. ISO 15489 presents the principles and methodology of records management that are consistent with the electronic record environment based on the record continuum theory, and the principles and methods on the appraisal of records presented in ISO 15489-1:2016 need to be analyzed in depth. This paper analyzes the concept and the logic of the appraisal of records presented in ISO 15489-1:2016 to find an improvement direction in accordance with the recent electronic record environment. For this purpose, it reviewed courses from the enactment of AS 4390 to the revision of ISO 15489 to understand the background of the appraisal principles of ISO 15489-1:2016. Based on this, the appraisal concepts and principles presented in ISO 15489-1:2016 were examined, and the process of the appraisal was analyzed.

This study aims to analyze criteria and characteristics for preservice elementary teachers' critiques of their peers' inquiry-based instruction. This study reviews critiques written by 31 preservice elementary teachers enrolled in an elementary school science inquiry methods course wherein the teachers designed and implemented inquiry-based instruction. These preservice teachers participated in inquiry-based instruction as if they were elementary students and then evaluated their peers' instruction. Analysis of the critiques reveals that preservice teachers evaluated their peers' instruction on the following criteria: instruction context, science content, teaching strategies, students, instructional goals, non-verbal attitude, and assessment. Their beliefs about teaching science inquiry were reflected in the critiques. Additionally, it was found that four orientation for teaching inquiry-didactic, academic rigor, activity-driven, inquiry orientation-reflected in critiques; some of critiques held more than one of these orientations. And they did not merely criticize but suggested alternatives to general teaching strategies; furthermore, of inquiry-instruction specific teaching strategies. They showed higher epistemic understanding of inquiry-based instruction after mid-term demonstrations. The evidence demonstrated that the proportion of critiques specifically about inquiry-based instruction increased after the mid-term demonstrations. Moreover, the post mid-term critiques emphasized interaction between students as well as understanding of the nature of science. These findings could provide implication for teaching inquiry and criticizing others' instruction as part of elementary school science courses in preservice elementary teacher education.
