Purpose: This study was to investigate the correlation between pain, disability and quality of life among adolescents and office workers with neck and shoulder pain. Methods: Twenty-four subjects (mean age=24.92 years, SD=3.94, range=20-37) with neck and shoulder pain participated in this study. The outcome measures of the study were visual analogue scale (VAS), neck disability index (NDI), shoulder pain and disability index (SPADI), short form-36 (SF-36) for neck and shoulder pain and disability, quality of life. Pearson's correlation and Speaman's rank correlation were used to measure the association between VAS and NDI, SPADI, SF-36. Results: The VAS showed a positive correlation between weak to moderate with the NDI and SPADI, but no significantly correlated (${\rho}=0.34$, ${\rho}=0.25$). The moderate positive correlation and significant correlation were observed between NDI and SPADI (${\rho}=0.43$, p<0.05). The PCS of SF-36 was significantly negative correlated with the VAS (${\rho}=-0.24$), NDI and SPADI (${\rho}=-0.63$, ${\rho}=-0.59$, p<0.05). Conclusion: The pain and disability of neck and shoulder has closely relevance. And, the pain and disability of neck and shoulder has a negative impact on the quality of life.

Background : Previous studies have proven beneficial in labor analgesia to use subarachnoid sufentanil(alone or with adjuvant) on parturients in early first stage of labor. We designed this prospective study to evaluate analgesic efficacy and side effects of subarachnoid sufentanil plus bupivacaine in women with cervical dilatation of 7 cm greater. Methods : This was an open-label, nonrandomized trial of 32 parturients in late first stage labor who requested labor analgesia. After signing the consent form each patient received subarachnoid sufentanil (10 ${\mu}g$) and bupivacaine (2.5 mg). Patients were asked to rate their verbal pain score (0-10 scale) before regional anesthesia and 5 minutes after subarachnoid injection, and every 20 minutes thereafter until delivery or request for additional analgesia. Blood pressure, pruritus, Bromage motor block score, mode of delivery and need for supplemental analgesics were recorded. Results : Thirty women were included in the study. Mean pain scores (mean${\pm}$SD) were $8.7{\pm}1.0$ pre-spinal, $0.7{\pm}1.5$ 5 minutes post-injection, and remained less than 5 for 130 minutes after spinal injection. Of 30 patients, 24 had unassisted vaginal delivery, 4 instrumental vaginal delivery (vacuum), and 2 cesarean delivery. Of 28 patients who delivered vaginally, 19 did not require supplemental analgesics and had a delivery pain score of 5 or lower. Blood pressure decreased in three patients after spinal analgesia (p<0.05), which necessitated treatment. The Bromage motor block score was 0 in 26 patients and 1 in 4 patients. Pruritus was noted in 22 patients. Conclusion : Subarachnoid sufentanil-bupivacaine provides rapid analgesia for an effective duration of approximately 130 minutes in parturients in late first stage of labor.

A study on the method of evaluation the urban amenity structure in Pusan city was established. Finally a survey sites out of 41 regions were selected on the basis of questionnaires : Taejong-dae and Haeun-dae as a seascape, Pumosa and Daesin-park as a mountain, Daechong-park and Seongjigok-park as a mixed, and Chungryulsa, Yongdoosan-park and U. N. Cemetry as a urban type. The abstracted results of amenity elements were revealed as natural environments including convex type as beach, reservoir, valley and mountain, and plant elements including woods and flower beds which raised amenity. The elements of social surroundings including children's playing, the aged's rest, and elements of structures including historic and memorial structures and high buildings. Amenity element made up of each space by region were abstracted from the Semantic Differential method. According to the factor analysis on the ground SD scale values, Kaiser's measure of sampling adequacy for 24 variables is 08602 and very high. Four factors including pleasantness, healthiness, convenience and safety showed 54.42 percent for total variance. By means of multiple regression, the model was as follows : Y=1.6636+0.3684X4+0.1955X11+0.1614X15-0.1688X23+0.1468X24. Therefore, Y:amenity, X4:beautiful-ugly, X11:clean-dirty, X15:creative-imitative, X23:cozy-dreary, X24:free-restrained. All variables in the model were significant at 0.001 level. According to the results of regression on satisfaction, the variables of satisfaction affecting amenity are the size of green space, the condition of management and the harmony with the surroundings. I think the considerating on the above could improve amenity of each region and further Pusan city.

The device performance of nano-scale center-channel (CC) double-gate (DG) MOSFET structure was investigated by numerically solving coupled Schr$\"{o}$dinger-Poisson and current continuity equations in a self-consistent manner. The CC operation and corresponding enhancement of current drive and transconductance of CC-NMOS are confirmed by comparing with the results of DG-NMOS which are performed under the condition of 10-80 nm gate length. Device optimization was theoretically performed in order to minimize the short-channel effects in terms of subthreshold swing, threshold voltage roll-off, and drain-induced barrier lowering. The simulation results indicate that DG-MOSFET structure including CC-NMOS is a promising candidates and quantum-mechanical modeling and simulation calculating the coupled Schr$\"{o}$dinger-Poisson and current continuity equations self-consistently are necessary for the application to sub-40 nm MOSFET technology.

Objective: The aim of the current study was to evaluate changes in treatment outcomes in terms of health-related quality of life (HRQoL) and symptom burden at zero, one, three, and six months after an initial diagnosis of colorectal cancer. The demographic and clinical characteristics that account for outcome changes in patients were investigated using a repeated measures framework. Methods and Materials: A cohort study was performed of 134 colorectal cancer patients followed from diagnosis to 6 months post-treatment in Central Taiwan. HRQoL and symptoms were assessed at diagnosis and one, three, and six months thereafter. The Functional Assessment of Cancer Therapy-Colon (FACT-C) questionnaire, VAS pain, and the Memorial Symptom Assessment Scale (MSAS) were used for data collection. A generalized estimating equation (GEE) was applied for statistical analysis. Results: The majority of the patients were male (55%) and married (91.5%). The mean age was 60.4 years (SD = 11.71). Most were diagnosed stage III and IV colorectal cancer (54.5%). All underwent surgery; some also received chemotherapy (CT) or concurrent chemoradiation therapy (CCRT). The results of the GEE showed that overall, the HRQoL, pain, and symptoms of the patients significantly improved over the treatment period. Patients with stage IV disease who had received surgery and CCRT showed the worst HRQoL. Females, patients with comorbidity, and stage IV patients had higher pain scores over time. Female and stage IV patients had more severe physical symptoms, whereas stage II and IV patients had worse psychological symptoms over time. Conclusion: The patients' HRQoL, pain, and symptoms significantly improved over the 6-month treatment period. Certain patient and clinical variables accounted for changes in treatment outcomes regarding HRQoL and symptom burden in colorectal cancer patients.

Objectives : Lumbar disc herniations are common conditions which induce severe pain and disability. We assessed the clinical effectiveness of Korean medical combination treatment. Methods : This is an observational study. We reviewed the medical records of 46 patients with lumbar disc herniations, who attended intensive Korean medical combination treatments at Mokhuri Neck and Back Hospital, Korea during March, 2012 to October, 2012. All the patients took combination treatments of acupuncture, Chuna and herbal medicines during the hospitalization treatments. Zero to ten pain numerating rating scale(NRS) of pain and SF-36 were assessed before and after treatments. Results : During the period, 46 patients with lumbar disc herniation participated in the treatments, respectively. Average admission duration were 20.32 days(SD 9.67) in lumbar disc patients. For lumbar patients, low back pain NRS decreased from $5.84{\pm}2.58$ to $2.12{\pm}1.74$(p<0.001) and radiating pain from $6.25{\pm}2.30$ to $2.59{\pm}1.97$(p<0.001). Total SF-36 score increased significantly after treatment in lumbar disc patients(p<0.001). Conclusions : Korean medical combination treatment might be effective in reducing pain and improving life quality of patients with lumbar disc herniation.

As chip operating frequency increases, there is growing concern about on-chip interconnect inductance. This paper presents a two-step inductance screening tool to select interconnects with significant inductance effects in a VLSI design. Test chips designed in different CMOS technology nodes are examined. The inductance screening results show that 0.1% of the nets in a design have inductance problems with chips running at its operating frequency, supporting the necessity of a screening process instead of adding inductance model to all the nets in the design. The increase in resistance due to geometry scaling will strongly affect the significance of inductance on delay as technology and frequency scale. Since higher frequency worsens inductance problem and geometry scaling alleviates it, inductance screening tool can provide useful guidelines to circuit designers.

In this paper, a novel 2-level-search sphere decoding algorithm for multiple-input multiple-output (MIMO) detection and its VLSI implementation are presented. The proposed algorithm extends the search space by concurrently performing symbol detection on 2 level of the tree search. Therefore, the possibility of discarding good candidates can be avoided. Simulation results demonstrate the good performance of the proposed algorithm in terms of bit-error-rate (BER). From the proposed algorithm, an efficient very large scale integration (VLSI) architecture which incorporates low-complexity and fixed throughput features is proposed. The proposed architecture supports many modulation techniques such as BPSK, QPSK, 16-QAM and 64-QAM. The sorting block, which occupies a large portion of hardware utilization, is shared for different operating modes to reduce the area. The proposed hardware implementation results show the improvement in terms of area and BER performance compared with existing architectures.

For deep submicron (DSM) very large scale integrated circuits (VLSI), it is well known that interconnects have become the dominant factor in determining the overall circuit performance. Buffer insertion is an effective technique of interconnect optimization. When a net has an excessive propagation delay, one or more buffers can be inserted to reduce the delay. Buffers also reduce the crosstalk between neighboring wires. While many conventional methods insert buffers net by net. we have developed new techniques in which buffer locations are simultaneously optimized for all nets. This is to avoid the difficulties in finding the right ordering of nets for buffer insertion. since several nets may compete for a buffer location. We also study buffer insertion with multiple fan-out nets to optimize critical path delay. Elmore delay model is used for delay calculation and the number of buffers for each net is determined to optimize the delay.

Objectives The purpose of this study is to assess the effectiveness of Chuna manual therapy for shoulder pain in hemiplegic patients after stroke. Methods For a systematic review and meta-analysis, we set a key question in accordance with participants, intervention, comparison, outcome, study design (PICO-SD). we searched for clinical studies that conducted chuna manual therapy for shoulder pain in hemiplegic patients after stroke 7 databases until September 2019. Only randomized controlled trials were chosen. Results Total 14 randomized controlled trials were chosen for systematic review and meta-analysis. 9 studies used efficacy rate as evaluation tool, and 8 used visual analogue scale. Pressure method (壓力型) was used in 11 studies, followed by osteopathy method (整骨型) and wave motion method (波動型) in 9 studies. Chuna manual therapy showed statistically significant pain reduction effect. Through meta analysis, Chuna manual therapy showed significant pain reducing effect except the study with Chuna manual therapy and electroacupuncture compared to electroacupuncture only. Conclusion As a result, Chuna manual therapy showed statistically significant effect in pain reduction. However, almost studies were evaluated in a state of having probable high risk of bias. This suggests that it requires attention to make an interpretation in this study. Furthermore, more clinical research need to be accomplished in the future.
