Purpose: A descriptive study was conducted to examine the levels of distress, state anxiety, and physiologic responses in postoperative patients under patient controlled analgesia (PCA), and to determine correlations among the variables. Method: The study sample included women who underwent an elective hysterectomy procedure or other gynecologic surgeries(N=100). Subjective distress was assessed by visual analog scales around 8 hours postoperatively. Trained nurses collected objective distress data through observation of subject's behavior and vital signs. Data were analyzed with frequencies, percentages, means, Pearson correlation coefficients, ANOVA, and the Scheffe post test using SPSS/PC 11.0. Result: Subjective distress, objective distress, and state anxiety scores were relatively low, except pain scores(5.31 out of 10.0) among sub-scales of subjective distress. Women who had a total abdominal hysterectomy showed significantly higher levels of both subjective distress and state anxiety than those after a minor gynecologic surgery. In relationships among variables, subjective distress correlated positively with postoperative state anxiety, but not with the amount of analgesic medication, verified by further analysis on sub-scales of subjective and objective distress. The higher the levels of state anxiety, the higher the levels of tension, dyspnea, facial change, and systolic blood pressure observed. Conclusion: Regardless of effective pain management, most postoperatively experienced distress in gynecological patients was derived from surgery associated anxiety and pain. Specific psychological strategies should be established as well for those with high levels of state anxiety to facilitate prompt recovery.

Epilepsy constitutes a significant public health problem, and even the newest drugs and neurosurgical techniques have proven unable to cure the disease. In order to select a group of isolates which could generate an active compound with neuroprotective or antiepileptic properties, we isolated 517 actinomycete strains from soil samples taken from Jeju Island, in South Korea. We then screened these strains for possible anti-apoptotic effects against serum deprivation-induced hippocampal cell death, using the 3-(4, 5-dimethylthiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) assay as an in vitro test. The excitotoxic glutamate analog, kainic acid (KA), was used to induce seizures in experimental mice in our in vivo tests. As a result of this testing, we located one strain which exhibited profound neuroprotective activity. This strain was identified as a Streptomyces species, and exhibited the rifampinresistant genotype, Asn$(AAC)^$442, according to the results of 16S rRNA and rpoB gene analyses

This paper proposes real-time video transmission system by the car-mounted cameras based on MOST Network. Existing vehicles transmit videos by connecting the car-mounted cameras in the form of analog. However, the increase in the number of car-mounted cameras leads to development of the network to connect the cameras. In this paper, DSP is applied to process MPEG 2 encoding/decoding for real-time video transmission in a short period of time. MediaLB is employed to transfer data stream between DSP and MOST network controller. During this procedure, DSP cannot transport data stream directly from MediaLB. Therefore, FPGA is used to deliver data stream transmitting MediaLB to DSP. MediaLB is designed to streamline hardware/software application development for MOST Network and to support all MOST Network data transportation methods. As seen in this paper, the test results verify that real-time video transmission using proposed system operates in a normal matter.

Background: Lack of proper control of acute postoperative pain often leads to lingering or chronic pain. Several studies have emphasized the role of beta-blockers in reducing postoperative pain. Esmolol is a selective short-acting beta-blocker that produces few side effects. The purpose of this study was to examine the effect of intravenous intraoperative esmolol on postoperative pain reduction following orthopedic leg fracture surgery. Methods: In a clinical trial, 82 patients between 20-65 years of age with tibia fractures and American Society of Anesthesiologists (ASA) physical status I & II who underwent surgery were divided into two groups. Group A received esmolol and group B received normal saline. Postoperative pain was measured at three time points: entering the recovery unit, and at 3 h and 6 h following surgery, using the Visual Analogue Scale (VAS). A P value of < 0.05 was considered significant. Results: Mean VAS scores at all three time points were significantly different between the two test groups (P = 0.02, P = 0.0001, and P = 0.0001, respectively). The consumption of pethidine was lower in group A than in group B (P = 0.004) and the duration of its effect was significantly longer in time (P = 0.026). Conclusions: Intravenous intraoperative esmolol is effective in the reduction of postoperative pain following leg fracture surgery. It reduced opioid consumption following surgery and delayed patient requests for analgesics.

Objective: This study aimed to evaluate the effects of the Kaltenborn-Evjenth concept of nerve mobilization combined with intermittent cervical segment traction (ICST) on pain, Neck Disability Index (NDI) scores, range of motion (ROM) and endurance in persons with cervical radiculopathy (CR). Design: Two-group pretest-posttest design. Methods: Thirty subjects participated in this study and were randomly assigned to two groups. The ICST group (n=15) was performed simultaneously with nerve mobilization and cervical traction for the segment with cervical pain at the same time. The intermittent cervical total traction (ICTT) group (n=15) performed nerve mobilization and cervical traction for the whole cervical area at the same time. In this study, outcome measures such as the Visual Analog Scale (VAS), NDI, ROM, endurance (cranio-cervical flexion test), and passive intervertebral motion performed before and 4 weeks after the experiment were compared to investigate the effects of each intervention. Results: In both groups, there were significant differences in the VAS, NDI scores, and endurance, and there were significant differences between the two groups except for endurance (p<0.05). In the ICST group, significant differences were found in all ROM, and in the ICTT group, significant differences were found in only extension, and there were significant differences between the two groups (p<0.05). Conclusions: The ICST group showed more improvement than the ICTT group in pain, NDI scores and ROM. Moreover, our findings show that the ICST could be used as a new strategy for manual therapy in persons with CR.

In this paper, we proposed the adaptive local sigma filter reducing noises generated by an image sensor. The small noises generated by the image sensor are amplified by increased an analog gain and an exposure time of the image sensor together with information. And the goal of this work was the system design that is reduce the these amplified noises. Edge data are extracted by Flatness Index Map algorithm. We made the threshold adaptively changeable by the luminance average in this algorithm that extracts the edge data not in high luminance, but just low luminance. The Local Sigma Filter performed only about the edge pixel that were extracted by Flatness Index Map algorithm. To verify the performance of the designed filter, we made the Window test program. The hardware was designed with HDL language. We verified the hardware performance of Local Sigma Filter system using FPGA Demonstration board and HD image sensor, $1280{\times}720$ image size and 30 frames per second.

Objectives: The aim of this study was to evaluate the efficacy of microcurrent taping therapy and kinesio taping therapy. Methods: We included 58 participants who met the inclusion criteria and assigned them into two groups after the randomization. We allocated 29 participants to the microcurrent taping therapy group (MCT) and the other 29 to the general kinesio taping therapy group (GT). 27 participants completed the trial in the MCT group, 27 participants in GT. We attached "I" shaped 20cm tape along the erector muscle of the spine starting from the level of S2, and another 30cm tape on the iliac crest horizontally. These "I" shaped tapes were attached on two parts of the body and were performed the same way for both groups. This procedure was done 8 times and participants visited a total of 9 times including a final visit for evaluation. We measured Visual Analog Scale (VAS), Range of Motion (ROM) and Schober's test on every visit. Participants completed a questionnaire of Oswestry Disability Index (ODI) and Beck's Depression Inventory (BDI) on the first and last visits. Results & Conclusion: There was a significant effect of microcurrent taping therapy on lower back pain, but we could not establish the superior effect of microcurrent taping therapy compared with general kinesio taping therapy.

Objectives: This study was performed to assess whether herbal medicine and acupuncture before in vitro fertilizationembryo transfer (IVF-ET) is effective on clinical pregnancy. Methods: From May 2010 to January 2011, a prospective analysis study was performed in 38 patients planning to undergo IVF-ET after taking herb medicine and acupuncture treatment. This study investigated the pregnancy rate and analyzed the change of dysmenorrhea by visual analog scale (VAS), body heat and condition of premenstrual syndrome (PMS), vaginal discharge and menstruation status. Results: 1. During herbal medicine and acupuncture treatment, five patients (13.16%) naturally became pregnant and six patients (15.79%) withdrew. After treatment, 15 patients (39.47%) received IVF-ET, 12 patients (31.58%) did not. 2. The biochemical pregnancy rate was 26.67%, the clinical pregnancy rate 26.67%, miscarriage rate 25% and ectopic pregnancy rate was 0%. 3. After treatment, PMS, dysmenorrhea and dysmenorrhea VAS was significantly decreased and the overall menstrual status improved. 4. After treatment, temperature difference of CV17-CV12 and CV4-CV12 increased, but it was not a statistically significant difference. 5. After treatment, decrease of hemoglobin and protein and increase of total bilirubin and creatinine were statistically significant. All the blood test results were within normal levels which proves safety of treatment. Conclusions: This study suggests that herbal medicine and acupuncture treatment before IVF-ET shows similar pregnancy rates with existing rates, but contributes to increasing the possibility of natural pregnancy.

PURPOSE. This study aims to compare the marginal fitness of two types of implant-supported fixed dental prosthesis, i.e., cementless fixation (CL.F) system and cement-retained type. MATERIALS AND METHODS. In each group, ten specimens were assessed. Each specimen comprised implant lab analog, titanium abutment fabricated with a 2-degree tapered axial wall, and zirconia crown. The crown of the CL.F system was retained by frictional force between abutment and relined composite resin. In the cement-retained type, zinc oxide eugenol cement was used to set crown and abutment. All specimens were sterilized with ethylene oxide, immersed in Prevotella intermedia culture in a 50 mL tube, and incubated with rotation. After 48 h, the specimens were washed thoroughly before separating the crown and abutment. The bacteria that penetrated into the crown-abutment interface were collected by washing with 500 µL of sterile saline. The bacterial cell number was quantified using the agar plate count technique. The BacTiter-Glo Microbial Cell Viability Assay Kit was used to measure bacterial adenosine triphosphate (ATP)-bioluminescence, which reflects the bacterial viability. The t-test was performed, and the significance level was set at 5%. RESULTS. The number of penetrating bacterial cells assessed by colony-forming units was approximately 33% lower in the CL.F system than in the cement-retained type (P<.05). ATP-bioluminescence was approximately 41% lower in the CL.F system than in the cement-retained type (P<.05). CONCLUSION. The CL.F system is more resistant to bacterial penetration into the abutment-crown interface than the cement-retained type, thereby indicating a precise marginal fit.
