Objectives: Our review aimed to summarize and evaluate evidence on the effectiveness of bee venom acupuncture (BVA) in the treatment of shoulder pain. Methods: Randomized controlled trials (RCTs) evaluating the effectiveness of BVA on shoulder pain were searched up to October 2019 in 11 electronic databases (Medline, Embase, CENTRAL, CiNii, CNKI, VIP, Wanfang, Kmbase, NDSL, RISS, OASIS). The methodological quality of the included RCTs were evaluated using Cochrane Risk of Bias tool and a meta-analysis was performed. Results: Seven studies were included in the review, and four studies were included in the meta-analysis. Comparing BVA plus conventional therapy (CT) with saline injection plus CT, it showed an effect in favor of BVA plus CT in visual analog scale (VAS) and pain rating scale (PRS) (p = 0.02, p = 0.009, respectively). Comparing BVA plus physiotherapy (PT) with saline injection plus PT, it showed that there was no significant difference in VAS and verbal rating scale (VRS) between the two groups. Conclusion: This systematic review and meta-analysis suggest that BVA could be beneficial as an adjuvant treatment for shoulder pain.

Recently, the mining methods are changing from surface mining to underground mining because of the increment of the environmental issues and legal regulations. Therefore, the stability of underground openings is a major concern for the safety and productivity of mining operations. In this paper, a survey of structural geology and discontinuities were carried out at a limestone mine. The relevant mechanical properties of rocks were determined by the laboratory tests and rock mass classifications (RMR and Q-system) for the mine design and input data for the stability analysis. The dimensions of unsupported span for underground openings and pillar were decided based on the RMR values of rock mass classifications. The stability analysis for the suggested mine design was examined through the empirical methods (stability graph method and critical span curve) and 3-D numerical analysis (Visual-FEA).

This paper presents a comparative analysis of five different fusion methods. The five different methods to merge multispectral images and panchromatic image are IHS, FIHS, PCA, BT and WT methods. The comparative analysis based on visual analysis and quantitative analysis are performed using the merged results. From the results the FIHS method provide good result, BT, PCA, IHS and WT method show the next order.

Objective: This study was to resolve the limitations of the experimental environment and to solve the shortcomings of the method of measuring human gait characteristics using optical measuring instruments. Design: A cross-sectional study. Methods: Fifteen healthy adults without a history of orthopedic surgery on the lower extremities for the past 6 months were participated. They were analyzed gait variables using the smart guide and the 3D image analysis at the same time, and their results were compared. Visual-3D was used to calculate the analysis variables. Results: The reliability and validity of the data according to the two measuring instruments were found to be very high; gait speed(0.85), cycle time(0.99), stride time of both feet(0.98, 0.97) stride legnth of both feet(0.86, 0.88) stride per minute of both feet(0.99, 0.96), foot speed of both feet(0.90, 0.91), step time of both feet(0.77, 0.71), step per minute(0.72, 0.74), stance time of both feet(0.96, 0.97), swing time of both feet(0.93, 0.79), double step time(0.81), initial double step time(0.84) and terminal step time(0.76). Conclusions: In the case of the smart insole, which measures human gait variables using the pressure sensor and inertial sensor inserted in the insole, the reliability and validity of the measured data were found to be very high. It can be used as a device to replace 3D image analysis when measuring pathological gait.

This study develops a shaft analysis model for the optimization of the power transmission system. The finite element method was used for the shaft analysis model. The shaft and gear were assumed Timoshenko beams. Strength was evaluated according to DIN 743, and gear misalignment was calculated through ISO 6336 and the coordinate system rotation. The analysis software for a power transmission system was developed using Visual Studio 2019. The analysis results of the developed program were compared with those of commercial software (MASTA, KISSsoft, and Romax). We confirmed that the force, deformation, and safety factors at each node were the same as those of the commercial software. The absolute value of the gear misalignment of the developed program and commercial software was different. However, the gear misalignment tended to increase with increasing the displacement in the tooth width direction.

We propose an emotional facial avatar that portrays the user's facial expressions with an emotional emphasis, while achieving visual and behavioral realism. This is achieved by unifying automatic analysis of facial expressions and animation of realistic 3D faces with details such as facial hair and hairstyles. To augment facial appearance according to the user's emotions, we use emotional templates representing typical emotions in an artistic way, which can be easily combined with the skin texture of the 3D face at runtime. Hence, our interface gives the user vision-based control over facial animation of the emotional avatar, easily changing its moods.

This study examined the effect of visual art appreciation integrated with expression(integrated art appreciation) upon young children's drawing expression. The pretest-posttest control group design was chosen for the study. Twenty kindergarten children assigned to the experimental group were exposed to a program of integrated appreciation activity for 10 sessions. Another group of 20 kindergarten children were assigned to the control group taught by the traditional art teaching methods. Analysis of Covariance was applied for data analysis. Children in the experimental group showed higher scores in such drawing expressions as line, color, shape, composition, and theme.

The purpose of this study was to analyze the perception of wayfinding in public interior space. According to this study, a virtual reality simulation test was conducted to examine the effect of wayfinding. Theoretical research was used to explain the psycho-physiological effect of visual perception and case study was carried out to evaluate the physiological response of the subjects. For the physiological evaluation, two simulations with sign and color sample were chosen and the EEG was Used. Data were collected from May 15th. to June 15th. The subjects were 20 students of architecture department and frequency, percentage, ANOVA, T-test, multiple comparisons were used for data analysis.

With an increase in rail traffic, developing activities around structures of railway have been expanded. Inevitably, the changes to cross though sub-structures of railway have been getting increased. However, this situation affects on the safe operation of trains. Generated wheel load makes on the result in settlement on roadbed and damages on track materials. Therefore, via the numerical analysis were carried out for the box structure and subground using FEM analysis program called. Visual FEA/Geo 4.19. Parametric studies were performed by changing soil depth above box structure constructed in railway embankment. A standard live load was applied to simulate loads from train. Through this study, a minimum required soil depth above subground box structure was recommended based on deformation and stresses in concrete railway system.
