Wheat is one of important food crop in the world. However, wheat has some negative things that are allergen. Wheat includes four different allergen kwon as alpha-, beta- and gamma gliadin and amylase inhibitor. Recently, people are interesting to gluten free food or low gliadin food. To study about wheat allergies and research trend is important for future research like as wheat breeding and allergy reduction technology. In this study, we analyzed that the reported on the research field of wheat allergy have been reported until now, and was to provide direction for future research. The analysis of 235 episodes of major papers published from 2007 to 2016. The last 5 years from 2012, wheat allergy appears increasing number of related papers. The ratio of national papers 13% and 60% were published by the United States and other European countries, respectively. The fields of wheat allergen-related preclinical technology and wheat allergen related to genome research for discovery technology were represented high rate by 58% and 26%, respectively. In the case of Korea, significantly account genetic and breeding areas. Recently, however, the research of glutenin protein which is closely linked to wheat allergy is in progress. So, we expected to increase wheat allergy of the research is in the future in Korea.

It is the background that the provision of the mobile WiMAX femtocell trial service of a leading mobile telecommunication service operator using small base stations for indoor mobile broadband services and coverage expansion through eliminations of shadow areas in this paper. The paper presents an analysis result of trial subscribers' usage satisfaction for the mobile WiMAX femtocell service and suggests a market approach strategy of a mobile WiMAX femtocell service based on the analysis result. The interesting influence factors are extracted from wide influence factors suggested by existing research literature related with mobile service usage satisfaction and confined to a system quality, a service quality, and an account structure with consideration for attributes of mobile WiMAX femtocell service under exploring its early stages of service market. And then we analyze impacts of the factors to the mobile WiMAX femtocell service usage satisfaction. As a result, a system quality and an account structure have a tendency to provide considerable impacts to subscribers' usage satisfaction for mobile WiMAX femtocell service which is immature in both its technology and market. Therefore a market approach with the preferential consideration of the two factors will be valid.

Structural changing materials which can induce the physical deformation of materials are interesting research topics with various potential applications. Particularly, light among many driving mechanisms is a non-contact energy source, hence the light-responsive system can be used where non-destructive, local irradiation, and remote control is needed. Here, a mainchain azobenzene polymer is synthesized and its physical and optical properties are observed and compared to that of a polymer having a light-responsive azobenzene moiety on its side chain. Further dispersion onto polyvinylalcohol hydrogel is made and its dual stability and actuation are observed upon UV-visible light irradiation. Extended azobenzene polymer blend films show an anisotropic light-actuation with non-polarized UV light at room temperature. This physical shape change is quite reversible and occurs at lower temperature than that of any other reported systems including liquid crystalline elastomers. It is successfully demonstrated that the simple physical azobenzene/polymer blending has a very good actuation compared to that of LCEs which need an elaborate chemical design and it can be further used in the areas requiring a dimensional shape change.

Bovine tuberculosis is an important zoonosis worldwide. Mycobacterium bovis, the causative agent of this disease in cattle, is also a pathogen for humans and several economically important animals. The cases of tuberculosis are reported in two cow found at slaughter house located in Gwangju city. Histopathologically, in the lymph nodes, granulomas consisted of large areas of necrosis surrounded by variable thick bands of cellular infiltrate containing macrophages, Langhans-type multinucleated giant cells and lymphocytes. Lesions in the lung followed the same developmental pattern as did lesions in the lymph nodes with some exceptions. With the acid-fast staining, numerous mycobacteria were revealed in the lung and lymph nodes. M bovis was confirmed as a causative agent in these cattle using bacterial isolation and PCR and restriction fragment length polymorphism method based on a unique 12.7 kb fragment insertion sequence from the Mycobacterium tuberculosis genome and the pncA polymorphism, The insertion element IS6110 and IS1081 were present M bovis isolated from lungs and lymph nodes of cattle using PCR assay. These cases are interesting and important in public health aspect that M bovis-infected cattle were found during a routine post-mortem inspection at slaughter house.

This paper presents an importance sampling(IS) embedded experimental frame(EF) design for efficient Monte Carlo (MC) simulation. To achieve IS principles, the proposed EF contains two embedded sub-models, which are classified into Importance Sampler(IS) and Bias Compensator(BC) models. The IS and BC models stand between the existing system model and EF, which leads to enhancement of model reusability. Furthermore, the proposed EF enables to achieve fast stochastic simulation as compared with the crude MC technique. From the abstract two case studies with the utilization of the proposed EF, we can gain interesting experimental results regarding remarkable enhancement of simulation performance. Finally, we expect that this work will serve various content areas for enhancing simulation performance, and besides, it will be utilized as a tool to understand and analyze social phenomena.

Recognition and Tracking of interesting object is the significant field in Computer Vision. Mean-Shift algorithm have chronic problems that some errors are occurred when histogram of tracking area is similar to another area. in this paper, we propose to solve the problem. Each algorithm blocks skin color filtering, face detect and Mean-Shift started consecutive order assists better operation of the next algorithm. Avoid to operations of the overhead of tracking area similar to a histogram distribution areas overlap only consider the number of white pixels by running the Viola-Jones algorithm, simple arithmetic increases the convergence of the Mean-Shift. The experimental results, it comes to 78% or more of white pixels in the Mean-Shift search area, only if the recognition of the face area when it is configured to perform a Viola-Jones algorithm is tracking the object, was 100 percent successful.

Sensor deployment makes an effect on not only covering of the interesting area but also reliable data acquisition and efficient resource management of sensor, so that sensors must be deployed at their better place. In traditional static wireless sensor networks, however, it is impossible to deploy the sensors manually when they are distributed in unexploited, hostile, or disaster areas. Therefore, if each sensor has locomotion capability, it can re-deploy itself using the location information of neighbor sensors. In our previous study, we showed that moving sensors to the centroids of their Voronoi polygon is efficient for extending the coverage area. In this paper, we present an improved potential-field-based sensor self-deployment scheme by combining the centroid of Voronoi polygon with the traditional potential-field scheme. Simulation results show that our scheme can achieve higher coverage in shorter time and less movement than the traditional potential-field scheme.
