A literature study was progressed for oriental medical treatment for atopic dermatitis. Atopic dermatitis is a chronic or chronically relapsing, pruritic dermatitis. In oriental medical treatment is classified into the treatment of inside(herb tea), treatment of outside(medicine for external application), treatment of inside & outside. The method of inside treatment is improving in health for the spleen and clearing wetness(健脾利濕), extinguishing wind and refreshing fever(消風淸熱), nourishing blood and making dryness gloss(養血潤燥). The method of outside treatment is refreshing fever and removing wetness(淸熱燥濕), counteracting the poison and getting rid of itch(解毒止痒), removing the boil and forming proud flesh(消腫生肌). The method of inside & outside is improving in health for the spleen and clearing wetness(健脾利濕), refreshing fever and getting rid of itch(淸熱止痒). refreshing blood and extinguishing wind(凉血祛風).

Many studies for improving the railway vehicle's performance and comfort such as speed, weight and noise are currently in progress. Improving the structural characteristics of the vehicle for greater noise insulation is considered important for reducing disturbance due to noise, but measuring transmission loss entails large costs. This study explores an alternative method for estimating and measuring the railway vehicle's transmission loss that involves on applying the numerical analysis coupled with scaled reverberation chamber measurement. The transmission loss measurement using scaled reverberation chamber was performed after the compensation value was found through 1mm thickness(1t) specimen. For numerical analysis, a commercially available acoustics solver VA ONE was used. The proposed method is found to lead to transmission loss measurement comparable to the measurements based on large-scale reverberation chamber. Thus, it can be argued that a reliable method has been developed for measuring railway vehicle's transmission loss.

This paper proposes a method for improving the power quality of PMSG-based wind energy conversion system based on model predictive control in DC Microgrid. The MPC has a fast dynamic response. However, a large torque ripple deteriorating power quality is generated by a large and fixed switching period. On the other hand, the proposed method improves the power quality by setting the sampling time having zero torque error. The validity of the proposed method is verified through PSIM simulation.

In this paper, we proposed topology aggregation method that efficiently aggregating topology information in simple node topology. And, it improved QoS of networks by improving call success rate and call access time. Proposed method can improving performance of network by decreasing aggregation information and aggregating multi-links information between boundary nodes using the line segment scheme within bandwidth and delay parameter. To evaluate performance of the proposed scheme, we compare/analyze the current method with the proposed scheme in respect to call success rate, access time.

This paper presents a method for more efficient application of response surface methodology, one of the optimization methods, in optimal design of electrical devices. The proposed method is applied for improving torque performance of a prototype interior permanent magnet synchronous motor(IPMSM). In the end, the performance between the prototype and the optimized IPMSM is compared to verify usefulness of the method based on finite element analysis.

The purpose of this study is to introduce an efficient measure in Korean language education for learners of Korean by applying shadowing techniques which focus on improving not only listening and speaking skills but also reading and writing skills. First of all, the study discusses about the definition of shadowing along with the effect of shadowing. The second part will be about examining the proposed method related to shadowing technique which is comprised of original shadowing techniques and other techniques transformed from the original. Thirdly, the paper will be discussing background information of the shadowing technique in previous researches and experiments using shadowing techniques in Korean language education. Finally, there will be an introduction of learning measures that apply to skill unification. Most of the previous researches of the shadowing technique were limited to a few students with only mid-to-high level learners while this method could cover up to a wide range of learners. The most effective way of learning a foreign language would firstly be the suggested method and the focus should be on repetition and practice of the learners.

High injury and fatality rates remain a serious problem in the construction industry. Many construction injuries and fatalities can be prevented if workers can recognize potential hazards and take actions in time. Many efforts have been devoted in improving workers' ability of hazard recognition through various safety training and education methods. However, a reliable approach for evaluating this ability is missing. Previous studies in the field of human behavior and phycology indicate that the visual focus of attention (VFOA) is a good indicator of worker's actual focus. Towards this direction, this study introduces an automated approach for estimating the VFOA of equipment operators using a head orientation-based VFOA estimation method. The proposed method is validated in a virtual reality scenario using an immersive head mounted display. Results show that the proposed method can effectively estimate the VFOA of test subjects in different test scenarios. The findings in this study broaden the knowledge of detecting the visual focus and distraction of construction workers, and envision the future work in improving work's ability of hazard recognition.

Free-form buildings have a curved shape and are composed of geometric shapes, which require high precision. Therefore, this study proposed a new extrusion method, a piston method, that improves the precision of FCP by automatically extruding a predetermined amount of concrete by improving the aforementioned limitations. The technology to extrude a predetermined amount of concrete by applying pistons is expected to shorten construction period and increase economic efficiency by improving the precision and productivity of free-form panels.
