Background: This purpose of this study is to compare the analgesic efficacy, occurrence of motor block and other side effects of 48 hr continuous postoperative epidural infusions with 0.125% ropivacaine with fentanyl or 0.15% ropivacaine with fentanyl. Methods: Forty patients undergoing Cesarean section were randomly allocated into two groups. Both groups received epidural injection of 2.0% lidocaine 19 ml and 0.75% ropivacaine 2-5 ml with fentanyl $50{\mu}g$ for 20 minutes before surgery. Following surgery, a continuous epidural infusion using a two- day infusor was given for 40 minutes for post-operative pain control. Group 1 (n = 20) then received 0.125% ropivacaine and 6 ug/ml of fentanyl at a rate of 2 ml/h. Group 2 (n = 20) received 0.15% ropivacaine and 6 ug/ml of fentanyl at the same rate. Visual analog scales (VAS) for pain during rest and movement, sensory change and motor blockade were assessed for 48 hr after surgery. Results: There were no significant differences in VAS for pain during rest or movement. The incidence of side effects was similar in both groups. Conclusions: Using 0.125% ropivacaine with fentanyl via an epidural route provided similar pain relief and side effects as 0.15% ropivacaine with fentanyl.

Study results in the last decades show that amount and quality of physical exercises, then the active participation, and now the cognitive involvement of patient in rehabilitation training are known of crux to enhance recovery outcome of motor dysfunction patients after stroke. Rehabilitation robots mainly have been developing along this direction to satisfy requirements of recovery therapy, or focusing on one or more of the above three points. Therefore, neuro-machine interaction based active rehabilitation robot has been proposed for assisting paralyzed limb performing designed tasks, which utilizes motor related EEG, UCSDI (Ultrasound Current Source Density Imaging), EMG for rehabilitation robot control and feeds back the multi-sensory interaction information such as visual, auditory, force, haptic sensation to the patient simultaneously. This neuro-controlled and perceptual rehabilitation robot will bring great benefits to post-stroke patients. In order to develop such kind of robot, some key technologies such as noninvasive precise detection of neural signal and realistic sensation feedback need to be solved. There are still some grand challenges in solving the fundamental questions to develop and optimize such kind of neuro-machine interaction based active rehabilitation robot.

This study investigated Greene and Corwder(1984)'s modified PAS model, according to which, in a short-term memory recall task, the recency and suffix effects existing in auditory and visual conditions are mediated by the same mechanisms. It also investigated whether the auditory information and mouthed information are encoded by the same codes. Though the experimental manipulation of the phonological nature, the presence of differential recall effect of consonant-and vowel-varied stimuli in auditory and mouthing conditions which has been supposed to interact with the recency and suffix effects, was investigated. The result shows that differential recall effect between consonant and vowel exists only in the auditory condition, but not in the mouthing condition. Thus, this result supported Turner.

Tactile sensation is one of the most important sensory functions along with the auditory sensation for the visually impaired since it replaces the visual one of the persons with sight. In this paper, we present a tactile display device as a dynamic Braille display that is the unique tool f3r exchanging information among them. The tactile cell of the Braille display proposed is based on the dielectric elastomer, which is one of the electroactive polymers. It has advantageous features over the existing ones with respect to intrinsic softness, ease of fabrication, cost effectiveness and miniaturization. We introduce a new idea for actuation as well as additional considerations such as the driving circuit that makes it possible to drive multiple tactile cells in a high speed. Also, we describe the actuating mechanism of the Braille pin in details capable of realizing the enhanced spatial density of the tactile cells. Finally, results of psychophysical experiments are given to evaluate its effectiveness.

Neurodevelopmental outcomes of very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI) in Korea on 14 reports from 1984 to 2008 were analyzed. Follow-up rates were varied from 42.9% to 90.2%. Duration of follow-up ranged from 4 months to 5 years. The prevalence of cerebral palsy (CP) of VLBWI was as follows: 4.3-5.3% in 1980s, 7.1-9.1 % in 1990s and 3.6-15.6% in 2000s. CP was noted in 8.2-30.8% of ELBWI on studies reported in 2000s. Delayed Mental development was diagnosed in 2.0-17.9% of VLBWI and in 20.4-30.8% of ELBWI. Sensory impairments such as hearing loss or visual deficit were reported in 3.1-3.6% of VLBWI and 0.0-10.0% of ELBWI. Seizure disorder was reported in 5.3% of VLBWI by one report. No reports for minor neurodevelopmental dysfunctions in VLBWI and ELBWI were found from 1984 to 2008. It is necessary to establish basic protocols and nationwide systems for long-term follow-up study to obtain valuable data.

Despite recent clinical guidelines, the optimal therapeutic strategy for the management of refractory chronic cough is still a challenge. The present systematic review was designed to assess the evidence for efficacy and safety of gabapentin in the treatment of chronic cough. A systematic search of PubMed, Embase, Cochrane Library databases, and publications cited in bibliographies was performed. Articles were searched by two reviewers with a priori criteria for study selection. Seven relevant articles were identified, including two randomized controlled trials, one prospective case-series designed with consecutive patients, one retrospective case series of consecutive patients, one retrospective case series with unknown consecutive status, and two case reports comprising six and two patients, respectively. Improvements were detected in cough-specific quality of life (Leicester Cough Questionnaire score) and cough severity (visual analogue scale score) following gabapentin treatment in randomized controlled trials. The results of prospective case-series showed that the rate of overall improvement of cough and sensory neuropathy with gabapentin was 68%. Gabapentin treatment of patients with chronic cough showed superior efficacy and a good safety record compared with placebo or standard medications. Additional randomized and controlled trials are needed.

Purpose: The aim of this study was to analyze Neonatal Intensive Care Unit nurses' behaviors while soothing newborns with bronchopulmonary dysplasia. Methods: An observational study was used to assess nurses' soothing behaviors. Data were collected from September, 2012 to March, 2013 using an audio-video recording system. Participants were eight babies and 12 nurses caring for those babies. After obtaining parental permission, the overall process of each episode from nurses' engagement in soothing to the end of soothing was recorded. Then a researcher interviewed each participating nurse. Data from 18 episodes were transcribed as verbal and nonverbal nursing behaviors and then categorized by two researchers. Results: There were 177 observed soothing behaviors which were classified with the five sensory-based categories (tactile, oral, visual, auditory, vestibular). Most frequently observed soothing behavior was 'Gently talking' followed by 'Removing irritant', and 'Providing non-nutritive sucking'. Nurses' perceived soothing behaviors were similar to the observed soothing behaviors except for 'Gently talking'. Conclusion: Nurses used diverse and mixed soothing behaviors as well as recognizing those behaviors as essential nursing skills. Nurses' soothing behaviors identified in this study can be used to comfort babies and to enhance their developmental potential in accordance with individual characterstics or cues.

In the 1970s and 1980s, space installations in films became a new approach to film research. Many film directors and theoretical scholars believe that the space setting in films, other than textual stories, is an important core of film narrative research. Early film scholars have proposed that the film space with sensory narrative mode as the core motive force can promote people's in-depth understanding of the film content. Therefore, many researchers have tried to emphasize the importance of space in films through Hitchcock's films, but have not analyzed the elements and techniques of film space performance in detail. Reviewing the Hitchcock's classic crime film, through the space set in the traditional film, we can discover the movie techniques and concepts related to space. Therefore, this study takes Hitchcock's classic crime film as an example, and through analysis of film space expression techniques, attempts to propose factors for film space creation and bring new spatial perception effects to the audience.
