Objective: The purpose of this study was to investigate the effects of vibration resistance exercise (VRE) in patients with tennis elbow on strength, range of motion (ROM), function, pain and quality of life (QOL). Design: Randomized controlled trial. Methods: Twenty-seven participants were randomly assigned to either the VRE group (n=9), weight resistance exercise (WRE) group (n=9) or control group (n=9). Each group underwent hot compress for 15 minutes and electrotherapy for 15 minutes. The VRE group underwent exercises using a vibrating ball for 5 minutes. The WRE group underwent exercises using dumbbells for 5 minutes. All participants were evaluated on wrist extension strength using a hand-held dynamometer, grip strength level through an electric dynamometer, and ROM through a smartphone goniometer application before and after intervention. Patient-rated tennis elbow evaluation, Visual Analogue Scale and Short Form 8 were measured by questionnaires. Results: There were showed significant differences among the VRE, WRE and control group in wrist extensor muscle and hand grip strength, ROM, elbow function, pain and QOL after intervention (p<0.05). The VRE group showed a greater significant improvement in wrist extensor muscle strength and elbow function compared with the others (p<0.05). The VRE and the WRE groups had a more significant improvement in wrist extensor muscle and hand grip strength, ROM and pain compared with the control group (p<0.05). However, there were no significant differences in QOL among the three groups. Conclusions: Combining VRE with thermotherapy and electrotherapy appears to be more effective in improving wrist extension strength, ROM, elbow function, QOL in tennis elbow patients.

Some two years ago our company undertook a project on manufacturing network rationalization to maximize competitiveness through continuous improvement in manufacturing efficiency. One key outcome was the recognition of the benefits that could be derived from timely application of new technology or novel use of existing technologies and even more importantly the need to develop company wide strategies to maximize the impact of such applications. As a direct result an exercise was undertaken to identify the ten most promising technologies from a list of literally hundreds seen as having the capability of making a rapid impact on the manufacturing initiative. One of the outcomes of this exercise was the identification of Near Infrared Spectroscopy as a pivotal technology for improving process understanding, performance, and control to deliver consistent product quality cost effectively with broad applicability across our product range. While NIR had been in use in targeted areas on some of our sites for some years our new challenge was to develop a strategy to extend NIRs application, initially over 17 manufacturing sites, while concurrently expanding the NIR skill base company wide to ensure that the return on initial investment could be further maximized as shared applications across the remaining sites as required. This presentation will provide an overview of how life cycle based user requirement specifications were developed covering: ㆍSpectrophotometers ㆍSample interfaces ㆍSoftware ㆍEquipment and Software qualification ㆍCalibration transfer ㆍ Ease of developing effective user interfaces and control for applications transferred to a production area ㆍUser training ㆍWorld wide support The presentation will also describe the process adopted for vendor selection to ensure maximum utilization of the existing company wide NIR skill base and its future development to expedite applications of the technology in development, quality control and production areas.

Continuing Education institutions of the university will be activated to increase opportunities for adult education and to give educational functions of the university back to society, but professional development programs conducted by institutions does not recognize as a formal education because those programs do not share the quality of education using the university's infrastructure. In this paper, by breaking away from the issues of Continuing Education, we develop the incumbent professional development programs through the sharing of high-quality education programs of university, and analysis the effectiveness of those programs in which university students participate during their school vacation. The proposed programs was to verify the educational effect through survey of students who participated in the proposed training. Grafting professional development programs onto future engineering education of university would like to be introduced.

The typical reason of the private sector's increasing share in standardization is that the procedures of official standardization organizations are out of step with the rate of technical development. At today's so fast pace that the success of a technology is decided in the market even before it is standardized, several industry leaders jointly make their draft standard at the early stage of development, which becomes 'De fecto Standard.' To respond effectively to current trends of standardization where the market's decision is thought much of than official standardization procedures, it is necessary to shift from our current public sector-driven to private sector-driven standardization. Therefore, to vitalize the private sector-driven standardization in Korea, there is a need to: Run a standard foundation to secure stable resources for standardization Make information exchange between the govertment and private sector active and policy-making on standards consistent by designating a private organization to cover the roles, policies on standards, and support of the national standardization organization Establish a system to make private sector-driven standards approved as international standards Offer a training program to forster standard experts Publicize the importance of standards Promote standardization forums driven by private businesses, like the Integrated Forum. Maximize the benefits of linking standards and patents Now, Korea is on the threshold of developing into a world-class standard leader, and the private sector-driven standardization should be a stepping-stone for crossing over the threshold. This study is designed to suggest a method of promoting private sector-driven standardization to effectively cope with fast-changing international standards, based on the cases in developed countries.

Objectives : We examined the use of the moxibustion through survey on Korean Medicine Doctors (KMDs) on preparation of universal moxa product standard by fully reflecting opinions of practitioners and the industry. Methods : The questionnaire is composed of 25 questions including use of indirect moxa, side effects, complaints and improvements, general characteristics and so on, and were responded by 1,588 KMDs. For statistics, frequency analysis, chi-square analysis, T-test and ANOVA were conducted using SPSS 12.0 for windows, and the significance level was 0.05. Results : In this research, 91% of the responded KMDs was using moxibustion, and the proportion of using mediate moxibustion was shown as 63.2%. They used mediate moxibustion for side effects of direct moxa method such as risk of burn, ease of use, control of stimulation and so on. And it was mostly being conducted to women and 40 ages. Most respondents gave moxibustion treatments for the purpose of thermal stimulation on acupoint to musculoskeletal diseases. Most respondents were treating 1~2 pieces of moxibustion to patients by moxibustion points to those of 1~2 regions every time within 10 minutes. Regarding the frequency of side effects of mediate moxibustion, within 3% of respondents had experienced side effects, and the types were burn, flare and itchiness, odor and smoke. The dissatisfaction of mediate moxibustion products was moderate(2.00 out of 5 point scale), and went up public health doctors, the younger ages and the shorter clinical experience. Complaints on mediate moxibustion products were serious odor, poor attachment, risk of burn etc. Regarding ways to improve mediate moxibustion, the expansion of moxibustion's insurance cost carne out highest, followed by preparation of manual on efficacy, strengthening of training, acquiring evidence on efficacy, diversification of specifications, safety improvement, quality improvement of mediate moxibustion products. Conclusions: Many KMDs use for ease of use and give moxibustion treatments for thermal stimulation but they complain about safety, efficacy and quality of mediate moxibustion. After this it is considered that we have to elevate therapeutic effect through the improvement of mediate moxibustion products.

An Artificial Neural Network including a Radial Basis Function (RBF) and a Time Delay Neural Network (TDNN) was used to predict total dissolved solid (TDS) in the river Zayanderud. Water quality parameters in the river for ten years, 2001-2010, were prepared from data monitored by the Isfahan Regional Water Authority. A factor analysis was applied to select the inputs of water quality parameters, which obtained total hardness, bicarbonate, chloride and calcium. Input data to the neural networks were pH, $Na^+$, $Mg^{2+}$, Carbonate ($CO{_3}^{-2}$), $HCO{_3}^{-1}$, $Cl^-$, $Ca^{2+}$ and Total hardness. For learning process 5-fold cross validation were applied. In the best situation, the TDNN contained 2 hidden layers of 15 neurons in each of the layers and the RBF had one hidden layer with 100 neurons. The Mean Squared Error and the Mean Bias Error for the TDNN during the training process were 0.0006 and 0.0603 and for the RBF neural network the mentioned errors were 0.0001 and 0.0006, respectively. In the RBF, the coefficient of determination ($R^2$) and the index of agreement (IA) between the observed data and predicted data were 0.997 and 0.999, respectively. In the TDNN, the $R^2$ and the IA between the actual and predicted data were 0.957 and 0.985, respectively. The results of sensitivity illustrated that $Ca^{2+}$ and $SO{_4}^{2-}$ parameters had the highest effect on the TDS prediction.

A look-up table based vector adaptive filter is proposed in color inverse halftoning. Inverse halftoning converts halftone image into a continuous-tone image. The templates and training images are required in the process of look-up table based methods, which can be obtained from distributed patterns in the sample halftone images and their original images. Although the look-up table based methods usually are faster and show better performances in PSNR than other methods do, they show wide range of qualities depending on how they treat nonexisting patterns in the look-up table. In this paper, a vector adaptive filter is proposed to compensate for these nonexisting patterns, which achieves better quality owing to the contributed informations about hue, saturation, and intensity of surrounding pixels. The experimental results showed that the proposed method resulted in higher PSNR than that of conventional Best Linear Estimation method. The bigger the size of the template in the look-up table becomes, the more outstanding quality in the proposed method can be obtained.

To produce quality software products, engineers must feel personally responsible for the qualify of products. Superior products are not produced by mistake; engineers must strive to do quality work. Every engineer is different and has own process improvement method. To be most effective, engineers must plan their work and they must base their plans on their own personal data. To consistently improve their performance, engineers must personally use well-defined and measured processes. The Personal Software Process(PSP) is a self-improvement process designed to help software engineers control, manage, and improve the way they work. It is a structured framework of forms, guidelines, and procedures for developing software. Properly used, the PSP provides the historical data you need to better make and meet commitments and it makes the routine elements of your job more predictable and more efficient. Then, PSP is the very useful tool to train the students in Programming Language Course. This paper is to provide the concept of PSP/TSP and the sample curriculums for Program Language Training Courses. Personal Software Process(PSP) to train students of Programming Language Courses

To obtain a value-added product from the non-toxic brown-backed toadfish Lagocephalus gloveri (pufferfish), we developed a retort pouched pufferfish soup (RPS) and characterized its processing conditions and quality metrics. We found that the most appropriate manufacturing process for the RPS consisted of detoxifying and cold-water dipping the pufferfish flesh, blanching it, and adding it to the retort pouch along with other ingredients (hot-water extract of pufferfish head and carcass, radish, bean sprouts, and garlic), after which the pouch was sealed, sterilized (120℃, F₀ value 7.5-10 min.), cooled, and inspected. The moisture, crude protein, and total volatile basic nitrogen contents of the RPS were 97.2%, 1.3% and 7.7 mg/100 g, respectively. The total free amino acid content was 903.2 mg/100 g, and the main free amino acids were glutamic acid, taurine, lysine, glycine, threonine, alanine, arginine, proline, and hydroxyproline. Sterilizing the RPS for up to F₀ value 10 min. did not cause any major problems in terms of chemical or sensory qualities. This RPS has good storage stability and organoleptic qualities compared with similar commercial pufferfish soups and is suitable for commercialization as a value-added instant seafood soup.

To develop a value-added individually quick frozen (IQF) intermediate product from cultured sea mussel Mytilus edulis, we prepared IQF half-shelled roasted sea mussels (HRM) and IQF half-shelled boiled sea mussels (HBM). The processing conditions and quality metrics of the mussels were examined. The HRM and HBM were produced by washing and removing the byssus of raw sea mussels, followed by electric roasting or boiling. The roasted or boiled sea mussels were half-shelled, lightly washed with 3% saline water, rapidly frozen for 2 hours at -35℃, glazed, and packaged with a plastic film bag. The HRM and HBM had volatile basic nitrogen contents of 11.5 and 12.6 mg/100 g, and amino nitrogen contents of 607.9 and 534.2 mg/100 g, respectively. The HRM and HBM had hardness values of 4.31 and 2.99 kg/㎠, shearing force values of 992.2 and 507.7 g, free drip values of 8.9% and 10.2%, and expressible drip values of 7.0% and 8.1%, respectively. The free amino acid contents of the HRM and HBM were 763.1 and 560.7 mg/100 g, respectively. These results demonstrate that HRM have superior qualities compared to HBM and can serve as high-end shellfish when cooked.
