Generally, in order to avoid overlap with previous research and to initiate the innovative research, researchers must analyze patent information before research can begin. In this paper, the development of grading criteria using current trends in the wind power generation will be performed by analyzing the following criteria: technology position of major countries, impact factor each countries, patent family size, patent portfolios analysis, patent applied analysis, and analysis of nationality for a patent. This patent information for the wind power generation is expected to be useful in deciding the direction of future research.

We propose a pattern classification model using a selective perception ability of human beings. Generally, human beings recognize an object by putting a selective concentration on it in the region of interest. Much better classification and recognition could be possible by adapting this phenomenon in pattern classification. First, the pattern classification model creates some reference cluster patterns in a usual way. Then it generates an SPM(Selective Perception Map) that reflects the mutual relation of the reference cluster patterns. In the recognition phase, the model applies the SPM as a weight for calculating the distance between an input pattern and the reference patterns. Our experiments show that the proposed classifier with the SPM acquired the better results than other approaches in pattern classification.

With the recent development of deep convolutional neural network learning, deep learning techniques applied to single image super-resolution are showing good results. One of the existing deep learning-based super-resolution techniques is RDN(Residual Dense Network), in which the initial feature information is transmitted to the last layer using residual dense blocks, and subsequent layers are restored using input information of previous layers. However, if all hierarchical features are connected and learned and a large number of residual dense blocks are stacked, despite good performance, a large number of parameters and huge computational load are needed, so it takes a lot of time to learn a network and a slow processing speed, and it is not applicable to a mobile system. In this paper, we use the residual dense structure, which is a continuous memory structure that reuses previous information, and the residual dense channel attention block using the channel attention method that determines the importance according to the feature map of the image. We propose a method that can increase the depth to obtain a large receptive field and maintain a concise model at the same time. As a result of the experiment, the proposed network obtained PSNR as low as 0.205dB on average at 4× magnification compared to RDN, but about 1.8 times faster processing speed, about 10 times less number of parameters and about 1.74 times less computation.

Ontology merging describes the process of integrating two ontologies into a new ontology. How this is done best is a subject of ongoing research in the Semantic Web, Data Integration, Knowledge Management System, and other ontology-related application systems. Earlier research on ontology merging, however, has studied for developing effective ontology matching approaches but missed analyzing and solving methods of problems of merging two ontologies given correspondences between them. In this paper, we propose a specific ontology merging process and a generic operator, T-MERGE, for integrating two source ontologies into a new ontology. Also, we define a taxonomy of merging conflicts which is derived from differing representations between input ontologies and a method for detecting and resolving them. Our T-MERGE operator encapsulates the process of detection and resolution of conflicts and merging two entities based on given correspondences between them. We define a data structure, MergeLog, for logging the execution of T-MERGE operator. MergeLog is used to inform detailed results of execution of merging to users or recover errors. For our experiments, we used oriental philosophy ontologies, western philosophy ontologies, Yahoo western philosophy dictionary, and Naver philosophy dictionary as input ontologies. Our experiments show that the automatic merging module compared with manual merging by a expert has advantages in terms of time and effort.

In this research, we aim to analyze the trend of Huawei's PCT patent applications. As a result of analyzing Huawei's PCT patents by dividing temporal spans into three periods - the early 2000s, the late 2000s, and the early 2010s -, the following characteristics have been observed. First, the number of PCT patent applications has conspicuously increased from the early 2000s to the late 2000s and this trend has continued during the early 2010s. Second, in terms of a core technological field, whereas Huawei focused on the development of technologies in the 'H04L: transmission of digital information' sector during the early/late 2000s, it changed this field to the 'H04W: wireless communication networks' sector during the early 2010s. Lastly, in the case of the patent maps, it was found that while general communications technologies, as expressed with such keywords as 'user' and 'network,' were actively developed during the early/late 2000s, mobile phone-related technologies grasped this leading position, as shown with the keywords including 'user equipment,' 'base station,' and 'MME,' during the early 2010s. It was also noticeable that Huawei filed LTE-related patent applications more actively than Apple and Samsung Electronics, which implies that it will presumably pioneer the global market more aggressively than its competitors in the future.

Considering the importance of SMEs, which account for 88% of employment and 99% of domestic businesses, the government has implemented informatization policy support. On the other hand, due to budget limitations and the ability of the private market, it is time to transition to the new policy of the informatization support paradigm. This study evaluated the informatization policy support of SMBA by a comparison with the stage model to determine the future direction. The informatization development model is a step model divided into five levels ranging from the informatization initiation level to the strategic innovation level. The informatization policy of SMBA was focused on the development of automation and in-house integration, and business-to-business integration and strategic innovation step was found to be lacking. Based on these results, there are three implications for the informatization policy of the next SMEs. First, there is a need for a movement of the center of the support in the informatization step to the strategic innovative step. Second, by establishing an informatization road map, it is necessary to develop their own informatization capabilities according to the road map. Finally, it is important to improve the effectiveness of informatization support based on performance rather than policy providers.

This study seeks to identify the Entertainment tourist's pursuit values using means-ends chain theory. Data collection for this study is from July to October, 2012 in Jeju island. The procedure, Soft Laddering involves a series of one-on-one deep interviews with tourists who enjoyed performance arts. To carry out this study, first of all, contents analysis was employed to interview results. Second, Implication Matrix was made by contents analysis which showed direct and indirect relations. Finally, HVM was mapped for value systems. The results showed that Entertainment tourist's pursuit values were classified resulting in three values: Aesthetics, Communication with others, Pleasure. Especially in entertainment tourism, the major attributes was fun; the consequences was sensorial pleasure; the ultimate pursuit values was pleasure. These results support that entertainment tourists is homo ludens and entertainment tourism's marketer should concentrate on story-watching than story-telling.

This study aims to show why we have to introduce SOA paradigm in the Cadastral Information System for coping with domestic and foreign IT environments flexibly and strengthening inner capability. We search the trend of up-to-date IT paradigm such as Enterprise GIS, SOA and etc. from this, we worked out the concept of Cadastral Information System. we also could see the introduction case of the domestic and foreign next generation Cadastral Information System, there is implications for us. also, we analysis the general condition about information system which KCSC(Korea Cadastral Survey Corporation) own in a general way and estimate the SOA level degree for each information system. and on that base, we set up SOA loadmap for implementation the next generation of Cadastral Information Service. This is an important step for building ideal future information systems which KCSC hope to be. For realizing this, we focus our inner capability on integration without duplicate and re-using the inner information infra.

The role of local decentralization and balanced regional development becomes important due to the concentration of population due to urbanization, and the development of tourism contents in local governments is actively being attempted. However, this is largely due to quantitative growth, and it does not offer tourist content that offers a different experience while utilizing regional characteristics. This means that it is important to develop programs and contents that emphasize the identity of the region by cultivating local characteristics and build a different image. However, most of the small regions where characteristic resources are difficult to find have a problem that it is difficult to develop different programs and contents due to relatively few development opportunities and financial constraints. In this study, it was considered that it is effective to analyze characteristic features of the region and utilize the possessed assets as much as possible. Therefore, we propose a service design process that effectively supports ecotourism, one of the regional revitalization plan using local eco - assets. In the process, Venn Diagram Position and Context Map methodology was developed and verified through Sutonggol Observation Path.
