  • In this paper, parallel decimal fixed-point multiplier which uses the limited range of Singed-Digit number encoding and the reduction step is proposed. The partial products are generated without carry propagation delay by encoding a multiplicand and a multiplier to the limited range of SD number. With the limited range of SD number, the proposed multiplier can improve the partial product reduction step by increasing the number of possible operands for multi-operand SD addition. In order to estimate the proposed parallel decimal multiplier, synthesis is implemented using Design Compiler with SMIC 180nm CMOS technology library. Synthesis results show that the delay of proposed parallel decimal multiplier is reduced by 4.3% and the area by 5.3%, compared to the existing SD parallel decimal multiplier. Despite of the slightly increased delay and area of partial product generation step, the total delay and area are reduced since the partial product reduction step takes the most proportion.

  • Purpose: The purpose of this study was to investigate the effects of proprioceptive exercise on the body alignment of elderly women. Method: The experimental group consisted of twenty elderly women who participated in proprioceptive exercise for 8 weeks. The subjects were measured using Global Posture System equipment for assessing their body alignment. Body alignment was measured at the ear, shoulder joint, knee joint and calcaneocuboid joint on the sagittal plane, and the left and right acromion process positions, the ASIS and the medial malleoulus on the coronal plane. The body alignment data was used to assess the changes before and after proprioceptive exercise. The data of the experimental group was compared and analyzed using the Wilcoxon singed-rank test between before and after proprioceptive exercise. The Mann-Whithney test was used to compare the experimental group and the control group. Result: The result of this study was that the body alignment of the experimental group at the ear and knee joint on the sagittal plane was significantly in alignment with the line of gravity (p<0.05) before and after proprioceptive exercise. The body alignment was statistically different (p<0.05) between the experimental group and the control group on the frontal plane and sagittal plane. Conclusion: This study showed that proprioceptive exercise does affect the body alignment in elderly women. This indicates that there is interaction that plays a crucial role for proprioceptive stimuli and the body alignment.

  • Purpose: The aim of this study was to investigate the effects of trapezius and serratus anterior strengthening exercise on the shoulder pain and muscle activation of patients with spinal cord injury and functional shoulder impingement syndrome. Methods: The study consisted of 10 patients with spinal cord injury who were hospitalized in Rehabilitation Hospital U, Uijeongbu, South Korea. The exercise was implemented three times a week for 10 weeks. In each session, the subjects performed one of a total of five types of exercise at mid-level intensity. The shoulder pain and disability index (SPADI) was used to evaluate the patients before and after the intervention. The muscle activation of the upper trapezius, middle trapezius, lower trapezius, and anterior serratus muscle was assessed by surface electromyography (EMG) at the beginning of the experiment and 10 weeks later. Wilcoxon's singed-rank test was conducted to determine differences in the pain index and muscle activation before and after the exercise. The level of statistical significance was set at ${\alpha}=0.05$. Results: SPADI scores significantly decreased after the exercise (p<0.05). In comparisons of muscle activation, there was a significant improvement in the upper trapezius at $60^{\circ}$ shoulder joint flexion (p<0.05). There was no significant improvement at $90^{\circ}$ shoulder joint flexion. The middle trapezius showed a significant improvement at $120^{\circ}$ shoulder joint flexion (p<0.05). Conclusion: Trapezius and serratus anterior strengthening exercise reduced pain in spinal cord injury patients with functional shoulder impingement syndrome. The decreased muscle activation of upper trapezius and increased muscle activation of the anterior serratus muscle at $60^{\circ}$ shoulder joint flexion point to positive effects of the exercise on supraduction of the scapula.

  • Fascin, a cytoskeleton actin binding protein, functions in cell adhesion and cell migration. Fascin is also known as a candidate biomarker for various cancers, however, regulatory mechanisms of fascin expression remains little understood. In this study, we found an abnormal bristle phenotype, which is similar to that of the Drosophila fascin mutant, in Drafmutant flies. Hence, we investigated whether fascin expression is regulated by Raf signaling. RT-PCR and Western blot analysis showed that Drosophila fascin expression was down-regulated in Draf mutant flies and the level was increased in larvae expressing the oncogenic form of Draf (Draf$^{got}$) under the GAL4-UAS system. Immunostaining analysis showed increased fascin in the hemocytes over-expressing Draf$^{got}$. Our results indicate that fascin expression is regulated by Raf signaling and suggest that Raf signaling may play an important role in the actin cytoskeleton-associated developmental process and tumor progression via regulation of fascin gene.

  • Objective : The purpose of this study was to investigate the effects of bimanual intensive training on Upper Extremity Function and activities of daily living in stroke patients. Methods : The subjects were 18 patients who were diagnosed with hemiplegic stroke. They were randomly assigned to bimanual intensive training group (n=9) and unilateral intensive group (n=9). Bimanual training group performed bimanual task and unilateral training group performed one hand task for 1 hour per session, 5 times a week, for 4 weeks. Chi-square test, Wilcoxon signed rank test, and Mann-Whitney U test were used for analysis. Results : The results showed that, upper extremity motor function and bimanual coordination were significantly improved in patients in the bimanual training group (p<.05). Additionally, the ratio of affected hand use and amount of use/quality of movement in the hemiplegic upper extremity in activities of daily living for patients in the bimanual training group were significantly improved (p<.05). Although the unilateral group improved motor upper extremity function and activities of daily living in the upper extremity (p<.05), it was not significantly different from that in the bimanual training group. In between-group comparison, bimanual coordination and ratio of the affected hand use in a day were significantly different (p<.05). Conclusion : It is reasonable to conclude that bimanual intensive training therapy is an effective intervention method to improve upper extremity motor function, and activities of daily living in stroke patients.

  • Background: Current evidence suggests that intravenous magnesium sulfate might be effective for reducing migraine pain. In a recent pilot study, we showed that intravenous caffeine citrate could reduce the severity of migraine headache. The objective of this study is to investigate the efficacy of intravenous caffeine citrate vs. magnesium sulfate for management of acute migraine headache. Methods: We conducted a prospective quasi-experimental study from January until May 2016 in two educational medical centers of Shahid Beheshti University of Medical Sciences (Shoahadaye Tajrish Hospital and Imam Hossein Hospital), Tehran, Iran. The study included patients who were referred to the emergency department and met the migraine diagnosis criteria of the International Headache Society. Patients were allocated into 2 groups receiving either 60 mg intravenous caffeine or 2 g intravenous magnesium sulfate. The pain scores, based on the visual analog scale, were recorded on admission, as well as one and two hours after receiving the drug. A Chi-Square test and student t-test were used for analysis of baseline characteristics. A Mann-Whitney U test and Wilcoxon singed rank test were used to analyze differences in the visual analogue scale (VAS) score between and within the groups respectively. Results: In total, 70 patients (35 patients in each group) with the mean age of $33.1{\pm}11.3years$ were included (64.3% female). For the Caffeine citrate group, the median pain score decreased from 9.0 (2.0) to 5.0 (4.0) after one hour and to 3.0 (4.0) after two hours. For the magnesium sulfate group, the pain score decreased from 8.0 (2.0) to 2.0 (2.0) after one hour and to 0.0 (1.0) after two hours. Both intravenous caffeine citrate and intravenous magnesium sulfate reduced pain scores significantly but the magnesium sulfate group showed more improvement than the Caffeine citrate group after one hour (P < 0.001) and after two hours (P < 0.001). Conclusions: It is likely that both intravenous caffeine and intravenous magnesium sulfate can reduce the severity of migraine headache. Moreover, intravenous magnesium sulfate at a dose of 2 g might be superior to intravenous caffeine citrate 60 mg for the short term management of migraine headache in emergency departments.

  • Singeing has always been equated with meat color alteration through lipid oxidation and microbial population. Singeing method has always been employed far removing duck feathers, however, the effect of singeing on storage characteristic of duck meat has not been investigated extensively. The study was therefore, designed to Investigate the effect of singeing on duck meat during storage extensively. For the purpose, study was categorized into three groups namely A, B, and C, representing 0, 50 and 70 seconds of singeing time. Singeing was performed on 100 birds in each group, however, only 20 singed birds from each treatment groups were further selected to analyse them subsequently during storage. Analysis revealed that with 70 seconds singeing time drip loss was significantly (p<0.05) higher at $6mgf/cm^2$ compared to 50 seconds of singeing. With 70 seconds treatment breast meat apparently appeared black, where as with 50 seconds treatment no change was observed. Breast showed low redness with more duration of treatment compared to less treatment duration. Yellowness increased, springiness declined and no change was observed in cohesiveness and chewiness with high treatment time. There was increase in the TBARS and VBN, freshness did not change for first 5 days, however, K values started to increase later on indicated decline in freshness. Conclusively, it was inferred from the study that 50 seconds singeing does not make much alternation in the quantitative traits and at the same time maintains the microbial level under permissible limit.

  • Purpose: This study examined the effects of a shoulder-strengthening exercise on muscle strength of shoulder flexors and extensors of caregivers. Methods: The study consisted of 19 caregivers (2 males and 17 females) employed by Medical Center B. All the participants took part in an 8-week shoulder muscle strengthening exercise, based on previous studies. In the first week, the subjects took part in a stretching exercise enhance the range of motion. In the second week, they participated in an exercise aimed at improving shoulder blade stability. From the third to seventh weeks, a resistance exercise of different intensities was applied in a phased manner. Finally, in the eight week, the subjects took part in plyometric exercise. Peak torque, average power, and total work of shoulder flexors and extensors in both sides were measured before and after the exercise at an angular speed of 120deg/sec using an isokinetic device. Wilcoxon's singed-ranks test was conducted to analyze differences in muscle strength before and after the intervention. Results: After the exercise, there was a significant improvement in peak torque and average power of flexors of the right arm. After the exercise, peak torque, total work, and average power showed a significant improvement in the flexors of the left arm (p<0.05). However, there was no statistically significant difference in extensor muscle strength in either arm after the exercise. Conclusion: Shoulder flexors of caregivers are utilized frequently in the workplace. Implementation of extensor-strengthening exercises, in addition to flexor-strengthening exercises, can contribute to reducing the incidence rate of shoulder injuries among caregivers.

  • Deonum preexisted prior to it being named. Of course, the object designated as deonum at that time is not the same as the object designated as deonum at this time. There have been historical transitions in the definitions of the term deonum. This paper traced the term deonum to its origin from another angle. On closer inspection about the possible use as the everyday language and the technical language in the field of arts except for pansori, the term deonum was essentially a word for a tune. Deonum was in the same category as deureum, a great word in the Korean traditional music. But the definition of deonum as a tune used in the early part of the former period of eight master singers or before that gradually disappeared for a long time. When the term deonum as an everyday language first entered the field of pansori, it meaned characteristic tune singed by master singers. As pansori develop artistically, the term deonum changed into the word refers to the sori part, and this example become common in the former period of eight master singers. Most sori part acknowledged as a deonum in the former period of eight master singers was a deonum as a creative repertories, the master singer's creative work, but a deonum as a popular repertories, the master singer's specialty, began to be acknowledged as a deonum after the latter period of eight master singers. The differentiation between the definitions of deonum as a sori part occured. And most sori part acknowledged as a deonum after the modern era of five master singers have belonged to a deonum as a specialty. In this context, it was confirmed that Cheong Nosik wrote Joseonchanggeuksa, with carefully considering the historical change of definitions of deonum. This book includes three definitions of deonum, a deonum as a tune, a deonum as a creative work, and deonum as a specialty.
