Objective : Eye movement desensitization and reprocessing (EMDR) has been established as an effective treatment for patients with posttraumatic stress disorder (PTSD). However, the literature is unclear as to whether EMDR is effective in the treatment of other psychiatric disorders. The purpose of this study was to evaluate the potential use of EMDR in the treatment of psychiatric disorders other than PTSD by using a clinician's impression of patient response and a subjective symptom evaluation. Methods : Seventeen diagnostically heterogenous patients without PTSD underwent an average of 4.3 sessions of EMDR. Symptom severity was assessed by the Clinical Global Impression-Change Scale (CGIC), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Symptom Checklist-90- Revised (SCL-90-R) before and after EMDR. Those whose CGI-C scores were 'very much improved' and 'much improved' after EMDR were classified as 'responders.' The patients' before and after treatment scores of symptom severity and group differences were compared. Results : Twelve of the 17 participants (12/17, 71%) were classified as 'responders.' The patients' scores on all of the scales, with the exception of the trait anxiety scale and obsession-compulsion scale of the SCL- 90-R, significantly decreased after treatment. There was no difference in sociodemographic and clinical variables between the responders and non-responders. Conclusion : The results of our study suggest that EMDR can be a promising candidate for the treatment of patients with psychiatric disorders other than PTSD, and thus further controlled studies are needed to determine whether EMDR can be applied to various psychiatric populations.

Background : The purpose of study in to grasp the level of perception of hospital workers on the patient safety culture, consider the difference in perception of patients safety culture according to medical service and finally find out a way to establish patient safety culture in hospital. Methods : As for the data, the analysis on frequency, t-test, ANOVA and tukey test were carried out by using SPSS 12.0. Result : The results of comparison among the positive response ratios on the patients culture of hospital workers showed that the subjects had perceived the teamwork within units most positively(74.1%), and perceived most negatively on the non-punitive response to error(16.2%)and the staffing(26.2%). 68.6% of subjects answered that the medical error were mostly of always reported. when daytime working hours are longer, perception of patient safety culture ranked low. In general, departments for direct medical service than departments for indirect medical service assessed patient safety culture high. Conclusion : Organizational learning and teamwork within units, communication openness, active support of hospital management for patient safety, and cooperation across the units would be crucial to promote the overall perceptions of patients safety of hospital workers and the level of patients safety in the units and to improve the quality of the event reporting system.

The objective of research is to investigate satisfaction of the child physical education which is recognized by teachers of child educational institutions. For this study, It was chosen the program satisfaction, teacher satisfaction, a tool satisfaction and effects as subordinate factors at the base of preceding research and theoretical background For searching such a this research, 197 data for investigation were collected from teachers who work at 60 institutions which are located in Seoul, Kyonggi and Inchon for example kindergartens, nursery schools, English & Art institutions and playhouses. It was used questionnaire for investigatory tool. Also It were used frequency analysis, t-test official approval and one-way ANOVA for data processing, and statistical numerical value is below 0.05 as a P value. The conclusions follows: First, in the point of satisfaction about the infant physical education according ages, 41 ages are the highest at the program satisfaction, the teacher satisfaction and tool satisfaction, and 31~35 ages are the highest at the effect satisfaction. In the point of satisfaction about the child physical education accodrding period of duty, workers who have worked over 7 years are the highest at the program satisfaction, and workers who have worked for 5~7 years are is the highest but workers who have worked below 1 years are the lowest at the teacher satisfaction and tool satisfaction. In the point of satisfaction about the child physical education according educational background, graduate students are the highest at the program satisfaction and teacher satisfaction, and undergraduate students are the highest at the tool satisfaction and effect satisfaction. Second, in the point of satisfaction about the child physical education according the child educational institution, Art & English institution is the highest at the program satisfaction, teacher satisfaction and effect satisfaction, playhouse is the highest at tool satisfaction. Third, in the point of elemental relations about the cruld physical education, the relation of program satisfaction, teacher satisfaction, facility satisfaction and effect satisfaction, the relation of teacher satisfaction, tool satisfaction and effect satisfaction, and the relation between tool satisfaction and effect satisfaction, all of them have interrelation. Though these results, teachers of the child educational institutions are satisfied with the child physical education compare to the past, and the child physical education has developed in quantity and quality. It needs to make agency, teacher and parent's effort together for remarkable development of the child physical education.

Noise and vibration are likely to disturb the sensory system of human body leading to psychological stress and thereby property damage. In this research, a cut out switch(COS) with a built-in acoustic absorber along with a COS fuse broken was developed to reduce percussion noise. This new system is based on a design approach that combines existing absorber systems: expansion type, resonator type, and acoustic absorber type silencer. The noise performance of the new system was simulated using the SYSNOISETM software under optimized parameters: the diameter of perforated plate 2 mm, the plate thickness 3 mm, the width of expansion room 25 mm, the impinging vortex room 14 mm, and the noise absorbtion room 10 mm. The results showed that it reduced noise by approximately 41.1 dB compared to the current systems available in the market. Furthermore, it showed reduced noise by approximately 12 dB more than a product with an acoustic absorber of the Fault Tamer(USA)

Background/Aims: Many recent studies have shown excellent outcomes of surgical resection for ruptured hepatocellular carcinoma (HCC). In addition, there are several reports suggesting that a ruptured HCC did not increase the risk for peritoneal dissemination of a tumor after surgical resection. However, the impact of HCC rupture on recurrence and patient survival has not yet been clarified. Methods: The medical data of patients who underwent surgical resection for ruptured HCC in our center between January 2011 and December 2015 were retrospectively reviewed. The outcomes of the patients were investigated. Results: Among 128 patients who underwent surgical resection for HCC, 5 patients (3.9%) had a ruptured HCC. All patients underwent elective operation in a stable condition. Transarterial chemoembolization (TACE) was performed for achieving hemostasis in four patients except one who achieved spontaneous hemostasis. Two patients had tumor recurrence and one patient died due to HCC recurrence during the median follow-up duration of 28.3 months (range, 24.3-62.3 months). One patient who developed late intrahepatic recurrence at 40.0 months after resection was managed well by means of radiofrequency ablation and TACE and is now alive for 5 years without any evidence of viable tumor. However, the other patient who showed early peritoneal seeding at 1.9 months after resection finally died despite aggressive treatments. Conclusions: Rupture of HCC might result in peritoneal seeding of the tumor in the early postoperative stage, which could lead to a poor result. Nonetheless, surgical resection may be the best treatment option yielding good survival, even for a ruptured HCC. (J Liver Cancer 2017;17:54-59)
