Objective : Retrospective analysis to compare the effect and complication of epidural patient-controlled analgesia (epidural PCA) with intravenous patient-controlled analgesia (IV PCA) for the treatment of the post-operative pain after posterior lumbar instrumented fusion. Methods : Sixty patients who underwent posterior lumbar instrumented fusion for degenerative lumbar disease at our institution from September 2007 to January 2008 were enrolled in this study. Out of sixty patients, thirty patients received IV PCA group and thirty patients received epidural PCA group. The pain scale was measured by the visual analogue scale (VAS) score. Results : There were no significant difference between IV PCA group and epidural PCA group on the PCA related complications (p=0.7168). Ten patients in IV PCA group and six patients in epidural PCA group showed PCA related complications. Also, there were no significant differences in reduction of VAS score between two groups on postoperative 2 hours (p=0.9618) and 6 hours (p=0.0744). However, postoperative 12 hours, 24 hours and 48 hours showed the significant differences as mean of reduction of VAS score (p=0.0069, 0.0165, 0.0058 respectively). Conclusion : The epidural PCA is more effective method to control the post-operative pain than IV PCA after 12 hours of spinal fusion operation. However, during the first twelve hours after operation, there were no differences between IV PCA and epidural PCA.

This paper presents an ARM-based SOC bus transaction verification IP and the usage experiences in SOC designs. The verification IP is an AMBA AHB protocol checker, which captures legal AHB transactions in FSM-style signal sequence checking routines. This checker can be considered as a reusable verification IP since it does not change unless the bus protocol changes. Our AHB protocol checker is designed to be scalable to any number of AHB masters and reusable for various AMBA-based SOC designs. The keys to the scalability and the reusability are Object-Oriented Programming (OOP), virtual port, and bind operation. This paper describes how OOP, virtual port, and bind features are used to implement AHB protocol checker. Using the AHB protocol checker, an AHB simulation monitor is constructed. The monitor checks the legal bus arbitration and detects the first cycle of an AHB transaction. Then it calls AHB protocol checker to check the expected AHB signal sequences. We integrate the AHB bus monitor into Verilog simulation environment to replace time-consuming visual waveform inspection, and it allows us to find design bugs quickly. This paper also discusses AMBA AHB bus transaction coverage metrics and AHB transaction coverage analysis. Test programs for five AHB masters of an SOC, four channel DMAs and a host interface unit are executed and transaction coverage for DMA verification is collected during simulation. These coverage results can be used to determine the weak point of test programs in terms of the number of bus transactions occurred and guide to improve the quality of the test programs. Also, the coverage results can be used to obtain bus utilization statistics since the bus cycles occupied by each AHB master can be obtained.

Background: We evaluated the improvement of pain and the increase in mouth opening after temporomandibular joint arthrocentesis and the possible association with various factors such as previous splint treatment, medication, and diagnosis. Results: We studied 57 temporomandibular joint disorder patients who underwent arthrocentesis at Korea University Anam Hospital. These patients (24 males and 33 females, aged between 15 and 76 years) underwent arthrocentesis that was performed by one surgeon. The degree of mouth opening (assessed using the maximum mouth opening: MMO) and pain (assessed using the visual analog scale: VAS) were assessed pre- and post-arthrocentesis. The study also investigated whether treatment modalities other than arthrocentesis (medication and appliance therapy) were performed. Statistical analysis revealed that there was a significant difference in mouth opening and pain after temporomandibular joint arthrocentesis. Preoperative appliance therapy affected the results of arthrocentesis, but it was not statistically significant. With regard to pain relief, preoperative diagnosis did not show a significant difference. However, with regard to maximum mouth opening, patients with disc displacement without reduction with limited mouth opening (closed lock) showed the highest recovery (11.13 mm). Conclusion: The average of MMO increase after arthrocentesis was 9.10 mm, and patients with disc displacement without reduction with locking (closed lock) showed most recovery in maximum mouth opening and it was statistically significant. The average pain relief of patients after arthrocentesis was 3.03 in the VAS scale, and patients using anterior repositioning splint (ARS) preoperatively showed the most pain relief.

Objectives This study was aimed at comparing clinical effectiveness among trigger point treatment, Self-exercise treatment, trigger point - self-exercise cooperative treatment for neck pain caused by traffic accidents. Methods 63 patients with neck pain by traffic accidents were divided into 3 groups. Different types of treatments were carried out for each groups ; group A with trigger point, group B with self-exercise, group C with trigger point and self-exercise cooperative treatment. 3 groups were also treated with general acupuncture and herb-medicine treatment. Pain threshold, visual analogue scale (VAS), and neck disability index (NDI) were checked on a daily basis. SPSS ver. 18.0 for Windows was used for analysis of data. The effectiveness of treatment of each groups were verified by using paired test and one-way repeated-measures ANOVA test, and the comparison of VAS, NDI and pain threshold were demonstrated by independent samples t-test. Results 3 groups all showed significant difference in pain threshold, VAS and NDI after 8 days later. Group C showed more improvement in pain threshold, VAS and NDI than shown in group A and B. In the first period (from pre-treatment to 4th day treatment) group C showed significant difference in NDI and pain threshold but not in VAS as compared to group A and B. In the second period (from 4th treatment to 8th day treatment), Group C showed significant difference in pain threshold, VAS and NDI as compared to group A and B. Conclusions Trigger point - self-exercise cooperative treatment is proved to be more helpful to improve the unstability and reduce neck pain than trigger point treatment or self-exercise treatment only, therefore eventually leading to better satisfaction for patients with neck pain.

Popular music unites people who have different genders, ages, locals, and values. Through the popular music, youth interchange their emotion and create their fashion. Fashion and music formed the twin pillars on which the first historically significant youth sub-culture was built. Glam rock and Punk rock which won popularity in the 1970s influenced the fashion of the times. The purpose of this study is to compare Glam and Punk make-up which appeared as a symbol of the rebel against an older generation. The methodology utilized in this study was the analysis of materials from the survey through the literature, internet sites, and visual references. The results of this study are as follows: In face make-up, Glam used a white base to appear cosmic; on the other hand, Punk used a white base to appear pale and horrid. In eye make-up, Glam used black, pink, and blue eye shadow, and accented the eye by using black eye lines. Punk used black eye shadow, and drew black circles or squares around eyes. In lip make-up, Glam used pink, purple, red, and black lip color and silver and pink lip gloss to glitter. Punk used red and black lip color to appear horrid. In body make-up, Glam used glitter powder to appear with a bright skin. Punk drew tattoos and horror patterns in their body. The common themes of Glam and Punk make-up were rebellion, androgyny, and the beauty of ugliness as well as a self-created persona.

In the modern society of the 21st century where the visuality is emphasized, the illustration which expresses one symbol by embodying it is getting more spotlight than the use of character. Specifically, the fashion illustration serves the role of image promotion in other fields, for such as book, magazine, etc, as well as the fashion, and is taking root in daily lives. In response to that, this study researched on the fusion style fashion and the fashion illustration by using the violet color. The violet color which symbolizes the mysticism is being applied to society and culture in various forms, and has been considered as a precious color that represents god since ancient time, and still possesses its mysterious image even in the modern times. Moreover, as the appearance of fusion styled clothes which consolidates the latest trend image of the west and east is combined with the mysterious image of the purple to express new cultural image beyond highlighting specific image element of a country, the study on the fashion illustration based on the clothes based on the purple and fusion style would be very interesting. This study tried to produce the work that aims at the practical study based on the purple & fusion style and the theoretical consideration of fashion illustration through the analysis and investigative study of preceding studies. The findings from the study is like this: First, the violet the color, which represents the mysticism, can be confirmed to be an sophisticated, elegant and attractive image color that leads the modern fashion. Second, the fusion style which is coming into the spotlight recently can be found to have a great visual effect of consolidating the image of the west and east through the mixture with the purple color. Third, it was confirmed in our production of works that the fashion illustration was expressing a mysterious and new fusion style by blending appropriately with the purple color.

Viktor and Rolf, despite their short career in the field, has been continuously giving a fresh impact on fashion design by grafting a surrealistic approach to their design works. As a basis of this study, we review the features of surrealistic drawing and the surrealistic features expressed in surrealistic clothes. The purpose of this study is to analyze the surrealistic features detected in the clothes designed by Viktor and Rolf on the basis of the above standard and review and predict the future trend in fashion. As for the research method, we review the previous researches and analyze the drawing works by some representative surrealistic artists, in particular, Schiaparelli's clothes in the 1930s, the clothes of surrealistic trend since 2000, and Viktor & Rolf's clothes. The result of the analysis is as follows. The surrealistic features of Viktor & Rolf clothes can be found in the movement of natural objects, the movement of everyday materials, the movement of clothing items, and visual illusion on clothes. As a whole, the surrealistic features clearly stood out in their clothes. High technology will rapidly change the modern society and we humans are likely to resort to something fresh or different as our emotion and feelings are getting tired and weary. Something that stimulates our feeling and emotion hidden behind our reason or logic will be reflected in design far more than something complex and functional. For this reason, as it reveals human imagination inherently, surrealism is expected to establish itself as a mega trend in the future.

This study was conducted to identify the social perception of schizophrenic patients through films expressed in schizophrenic patients. We analyzed 48 films and scenarios that have been screened for the last 40 years by content analysis method to perceive interpersonal and emotional perception, perception of families and treatment measures. Patients were violent, dangerous, and burdensome to the family. However, specific experience or internal description has increased, and attitude of family or patients related to treatment has been more actively described since 1996. In conclusion, the perception of patients seen negative, want to avoid, giving burdens and pain to others. Therefore, to improve the social perception of mental disorders, it is necessary to make active use of films that have a high impact on public perception, and try to study the influence of visual media on perception change.
