Result that study magnet nerve curer for treatment induced current generation and current of ion for development in main point incontinence, prostate, sphincter, nervous system, rigidity, headache, retrogression arthritis, ligament damage, Rheumatism arthritis, peripheral nerve etc., can classify by 4. Embodied do first, full bridge magnet occurrence chapter, and communication with PC is available, confirmed various action loops an experiment. Could confirm correct treatment probe second, woman and man disease person. Third, derived so that healing may be possible naturally by addition of apron form according to disease. Because composition of finally, treatment probe composes by act of negative plate form, manufacture is easy and cooling designed for easy direction. More superior result of cooling appeared than existing in incidental and ingredients, cooling efficiency, composition, complexity, convenience etc. that expense and composition manufacture very straightforwardly and experimental by 2 - Tank ways.

Replication of the factor structure of the TBAQ(Toddler Behavior Assessment Questionnaire Goldsmith, 1988) in Korean 2-year-old children was examined by Multitrait Multimethod matrix of observed and reported child behavior. Participants included 113 toddlers and their mothers. Three factors comprising 63 items were identified and labeled as easy, difficult and fearful. On the Child Behavior Checklist(Achenbach & Edelbrock, 1983) difficult temperament was positively related to externalizing while fearful temperament was positively related to internalizing problems. Observation of inhibited child behavior in both unfamiliar social and nonsocial situations demonstrated a positive relationship to observed inhibition of fearful temperament. Easy temperament correlated negatively with both social inhibition and internal behavior problems. Results supported construct validity of TBAQ factors for Korean 2-year-old children.

OPC has made it to improve the development of control and monitoring software. But it is difficult to understand COM/DCOM model that is a base technology of OPC and complex communication setting between OPC Server and OPC Client. Therefore, in this paper, we design and implement ActiveX based components that are enable to solve these problems. Implemented components provide a method for simple communication between OPC Server and OPC Client and a GUI environment for easy and fast setting of communication information. Also, they provide the architecture for efficient management of OPC Server's data. By using implemented component, easy development and efficient maintenance of OPC Client can be supported.

A new synthetic route for the lanthanum β-diketonate compounds via in-situ formed lanthanum alkyl complexes was developed in the process for the development of suitable MOCVD (metal-organic chemical vapor deposition) precursors of PLT, one of the promising material for the ferroelectric film. A series of lanthanum β-diketonate compounds were successfully synthesized by this method. This new method is found to have some merits; versatile method for almost every β-diketone, β-hydroxyketone, and β-hydroxyaldehyde, short reaction time, easy purification for high purity, moderate to high yield, and easy access to anhydrous compounds. In some cases, anhydrous oligomeric products fail to show the higher volatility. On the other hand, some lanthanum β-diketonates with aromatic groups such as La(1,3-biphenyl-l,3-propandione)3 are found to have favorable properties for a precursor of lanthanum oxide, one of major components of PLT, such as low melting point, and much higher decomposition temperature. A plausible pyrolysis mechanism is proposed by the TGA, where consecutive dissociation of R, CO, CH, C, and O fragments occurs.

Unity programs are largely recognized as game development tools. However, it has many functions built in, so it can be applied to various fields as well as game development. Therefore, in this paper, we propose a smart farm environmental control program using Unity and Photon. The proposed program has vast compatibility that is not limited to specific devices, and it is very easy to build network systems for remote control. In addition, the proposed programs were installed on various devices such as pc and smartphones, making it easy to control the smart farm environment system. Through experiments, it was confirmed that data transmission and reception between Windows and Android, other operating system environments, and that smart farm systems were operating normally.

Even though the recent development trend of wind turbine systems has been focused on larger MW Classes, the small-scale wind turbine system has been continuously developed because it has some advantages due to easy personnel establishment and use with low cost and energy saving effect. This work is to propose a specific structural design and analysis procedure for development of a low noise 500W class small wind turbine system which will be applicable to relatively low wind speed region like Korea. The proposed structural feature has a skin-spar-foam sandwich composite structure with the E-glass/Epoxy face sheets and the Urethane foam core for lightness, structural stability, low manufacturing cost and easy manufacturing process. Moreover this type of structure has good behaviors for reduction of vibration and noise. Structural analysis including load cases, stress, deformation, buckling and vibration was performed using the Finite Element Method. In order to evaluate the designed blade structure the structural tests were done, and their test results were compared with the estimated results.

With the development of information and communication technologies, popularization of smart phones, and relaxation of the government regulation, mobile easy payment service is rapidly growing as a major financial service. Therefore, this study examines factors that influence the intention to use mobile easy payment service through empirical analysis. We collected 386 responses by survey and formed structural equation modeling with AMOS 22.0. The results show that technical factors(relative advantage, security), individual factor(self-efficacy), situational factors(trust in prior services and satisfaction of prior services) had a positive effect on the perceived value. In addition, perceived value had a positive effect on the intention to use mobile easy payment services. Lastly, subjective norms are closely related to the relationship between perceived value and intention to use mobile easy payment services. The results can be expected to provide useful references to the Fintech related industry fields.
