Objectives The purpose of this study was to compare the effects between the degree of herniated intervertebral lumbar disc (HIVD) at L4-5 level and improvement of low back pain treated by Korean Medicine therapy. Methods 567 patients who received inpatient treatment from May 2014 to December 2015 in the Daejeon-Jaseng of Korean Medicine Hospital were divided into 6 groups by the degree of HIVD at L4-5 level confirmed with a Lumbar spine magnetic resonance imaging. All patients received a combination of treatment including acupunture, chuna manual therapy, pharmacopunture, herbal medication. They were compared and analyzed on the basis of improvement between measuring Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), EuroQol-5 Dimension Index (EQ5D Index) as they were hospitalized and as they were discharged. The statistically significance was evaluated by SPSS 23.0 for windows. Results After treatment, Normal stage on Intervertebral Lumbar Disc at L4-5 level group's Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), EuroQol-5 Dimension Index (EQ5D Index) improvement was $1.30{\pm}1.62$, $4.52{\pm}11.82$ and $0.04{\pm}0.11$ respectively. Bulging group's improvement was $3.25{\pm}2.81$, $8.28{\pm}13.02$ and $0.09{\pm}0.17$ respectively. Spinal canal occupying ratio (SOR) less than 20 group's improvement was $2.15{\pm}1.92$, $11.79{\pm}17.81$ and $0.13{\pm}0.23$ respectively. SOR 20 to less than 40 stage group's improvement was $2.13{\pm}1.92$. $10.79{\pm}15.93$ and $0.10{\pm}0.26$ respectively. SOR 40 to less than 60 group's improvement was $2.16{\pm}2.24$, $9.80{\pm}16.62$ and $0.15{\pm}0.25$ respectively. Surgery group's improvement was $2.47{\pm}2.21$, $11.64{\pm}18.53$ and $0.15{\pm}0.27$ respectively (p<0.03). But there was no statistically significance between 6 group's improvement after treatment (p>0.05). Conclusions After inpatient treatment by Korean Medicine therapy, Most patient's pain, disability and Health Related Quality of Life was improved significantly. But there was no statistically correlation between the degree of HIVD at L4-5 level and improvement of low back pain.

Nowadays the customer is classified with external customers and the inside customers. Which are not only end users who consume products but also all people who contribute to their earnings through the management activity of the enterprise. Furthermore, the fact that the external customer satisfaction index and inside customer satisfaction index are closely related is supported by many researches. It is interpreted if the inside customer satisfaction is not improved, achievement of the external customer satisfaction cannot be easy. In this paper, First, we will deduce the inefficient index through DEA model in each department after setting up the weight of items of inside customer satisfaction and measuring them. Second, as well as research entire models about improvement methods of inside customer satisfaction getting improvement methods for reaching a goal in the minimum amount of efforts.

To improve construction productivity and quality, and to make the construction environment safe, a new system, Robot-based Construction Automation (RCA), is currently being developed in Korea. To determine whether RCA is an improvement over traditional construction methods (TCMs), an evaluation method, called the Performance Evaluation Index (PEI), is suggested for RCA. The PEI considers the relationships among the factors influencing the performance of the system obtained using the Delphi method and the analytic hierarchy process (AHP). As the evaluation shows, RCA is much better than TCM except for three factors: the rate of work success, quality improvement by learning experience, and construction duration.

Smart phones have brought rapid changes in this competitive world. Smart phone application developers are trying their best to consider the customer requirements in the most efficient way while considering all its attributes. However smart phone service quality has been given less consideration comparatively during the last few years. This paper proposes a measurement method for improving service quality of smart phone application. This method combines the service quality performance model (SQPM) and process capability index (PCI). The service quality performance model is used to identify service items that require improvement. Process capability index is used as a measure for prioritization of those improvements. Case study was carried out to search out important communication application service attributes. customer satisfaction level data was collected for users who used the application service. A total of twenty four service attributes were found during this survey. Using the joint approach of SQPM and PCI, five significant service attributes were prioritized for service quality improvement.

Objective: Nonspecific low back pain (NS-LBP) causes pain and disability, affecting the neuromuscular system and altering gait patterns. The purpose of this study is to investigate the effect of improvement of low back pain symptoms through physical therapy on foot pressure and spatiotemporal gait parameters. Design: A pilot study. Methods: Participants received manual therapy and supervised therapeutic exercise, which consisted of 12 sessions for 6 weeks. Participants were assessed for pain intensity (a numeric pain rating scale), disability index (oswestry disability index), and spatiotemporal gait parameters before and after intervention. Wilcoxon signed rank test was used to analyze the before-and-after differences in a single group. Results: All seven NS-LBP patients completed the study without dropout. After six weeks of physical therapy, the numeric pain rating scale and oswestry disability index showed significant improvement (Z= -2.388, P=0.017). There was no significant improvement in both static and dynamic conditions in foot pressure (P>0.05). However, in the spatiotemporal gait parameters, there were significant differences in all variables except the right stance phase and left mid stance (P<0.05). Conclusions: In our pilot study, 12 sessions of physical therapy in NS-LBP patients improved gait quilty in spatiotemporal gait parameters. Similarly, it has resulted in clinically positive improvements in pain and disability.

Background: To evaluate the facial asymmetry, three-dimensional computed tomography (3D-CT) has been used widely. This study proposed a method to quantify facial asymmetry based on 3D-CT. Methods: The normal standard group consisted of twenty-five male subjects who had a balanced face and normal occlusion. Five anatomical landmarks were selected as reference points and ten anatomical landmarks were selected as measurement points to evaluate facial asymmetry. The formula of facial asymmetry index was designed by using the distances between the landmarks. The index value on a specific landmark indicated zero when the landmarks were located on the three-dimensional symmetric position. As the asymmetry of landmarks increased, the value of facial asymmetry index increased. For ten anatomical landmarks, the mean value of facial asymmetry index on each landmark was obtained in the normal standard group. Facial asymmetry index was applied to the patients who had undergone orthognathic surgery. Preoperative facial asymmetry and postoperative improvement were evaluated. Results: The reference facial asymmetry index on each landmark in the normal standard group was from 1.77 to 3.38. A polygonal chart was drawn to visualize the degree of asymmetry. In three patients who had undergone orthognathic surgery, it was checked that the method of facial asymmetry index showed the preoperative facial asymmetry and the postoperative improvement well. Conclusions: The current new facial asymmetry index could efficiently quantify the degree of facial asymmetry from 3D-CT. This method could be used as an evaluation standard for facial asymmetry analysis.
