In general, Levenshtein distance algorithm have a problem with not distinguish the consideration of vacabulary retrieve, because Levenshtein methode is used to vocabulary order are not defined. In this paper, we propose a improved Levenshtein methode, it effectively manage the vocabulary retrieve by frequency use of a vocabulary, and it gives the weight number which have a order between vocabularies. Therefore proposed methode have a advantage of solve the defect of perception rate in the case of increase the vocabulary, improve the recognition time become higher and it can be effectively retrieval space management.. System performance as a result of represent vocabulary dependence recognition rate of 97.81%, vocabulary independence recognition rate of 96.91% in indoor environment. Also, vocabulary dependence recognition rate of 91.11%, vocabulary independence recognition rate of 90.01% in outdoor environment.

The purpose of this study was to understand how a dental hygienist is viewed by students in terms of both image and job /employment perception using structural equations. This together with the incorporation of available online information would help in collating the necessary data for ensuring adequate manpower of dental hygienists' in the future. The collected data were analyzed using SPSS Statistics 24.0 and AMOS Graphics 21.0 statistics packages. It was found that students who perceive employment positively have a positive image of a dental hygienist even if a new infectious disease were to occur. They appreciate that a negative image of a dental hygienist's job during an epidemic could cause a negative perception of employment as a dental hygienist. Those who think negatively of the internet as a source of information believe that the internet has a lot of false information, is harmful, promotes anxiety, and has been shown to promote negative perceptions about employment as a dental hygienist. Those who think positively of internet information think that dental hygienists are susceptible to infection and can transmit infection, which has been shown to negatively affect their perception of employment. In conclusion, it is important to form an image of a dental hygienist through the recognition of the correct internet information in the period of new infectious diseases.

Even though there are many studies on emotion recognition using EEG, there is a few research on specific emotion recognition in detail. In this paper, we construct test videos and conduct congruent-incongruent test for analysis on fear of crime. We compared the differences of event-related potential of subjects before and after watching the video using the congruent-incongruent test and analyzed the fear that subject perceived. Our results demonstrate that subjects showed lower amplitudes for unexpected stimuli in the PZ, POZ, and OZ electrodes of the occipital lobe, which process visual stimuli. These results indicate that the perception of subject is slower for unexpected objects.

This study analyzed the recognition of local residents surrounding farmland conversion area. The details of the survey on the residents included recognition of farmland conversion, the usage and reason of farmland conversion in the surrounding area, impacts of farmland conversion on the local region and agricultural production, and change in farmland prices. According to the analysis, the aging of the local residents progressed, and the ratio of farming population was high in the case study area. There were many warehouse facilities and small scale factories in terms of farmland conversion in the case study area, due to the surrounding area characteristics of industrial complex and relatively cheaper land prices. The farmland conversion affected the local area and residents both positively and negatively, and the surrounding area's land prices rose. The policy implications, based on the findings in this study, indicate the following need to be carried out: the consolidation of action on farmland pollution upon farmland conversion, review of planned collective conversion mode, and return of the land price hike profits to the affected local area and residents. Actually, farmland conversion should be conducted, after a comprehensive and systematic review, because it affects the local area and residents in a complex way.

Art psychotherapy is widely accepted as an effective tool for diagnosis and treatment of psychological disorders. Important factors for art psychotherapy diagnosis, based on the projection theory that the world of the inner mind appears in drawings, include main color and imbalance of a drawing. This paper develops a system for a machine to determine the main color and the imbalance of a drawing by color recognition and edge detection. Our proposed color recognition procedure adopts NBS(National Bureau of Standards) distance between colors in HVC(Hue, Value, Chroma) color space which is most similar to the human eye's color perception. Our edge detection procedure applies blurring, clustering and transformation to a standard color in a series. Our system considers the numbers of pixels and clusters for each color as a criterion for main color and the frequency of edge coordinates for each region for imbalance. The proposed machine procedure, verified through case studies, can help overcome the subjectivity, ambiguity and uncertainty in human decision involved in art psychotherapy.

Recently the information system introduction and the application which use the computer are increasing. The efficient operation of information system helps corporations to improve productivity, customer service and corporate competitive power. SaaS(Software as a Service), which is the developed type of outsourcing in the area of information technology, is to use standardized and packaged application by hosting from the outside of enterprise. SaaS is not developed yet as much as people's interest about that in the initial stage, but its related technology and service capacity are accumulated after repeated trial and error, and it's ready to activate the industry. In the area of information system, studies on the measurement of service quality were followed. But there is little study on service quality measurement in the field of SaaS(Software as a Service). The purpose of this study was to divides the SaaS with e-SERVQUAL and it consider the relationship with the perceived recognition and the usage intention. According to this, variables of traditional research were rejected because SaaS is not developed yet in Korea. But information had a strong effect on perceived recognition. Therefore, business related with in SaaS must have provided a correct information about various applications.

In this study, the eating out behavior and recognition of salinity in restaurant food in Jecheon area were examined. Demographic characteristics of the subjects, eating out behavior and perception of salinity in food purchased in restaurants were surveyed. Also salinity of the high Na-containing menus were measured using salimeter. Exactly 51.6% of the study subjects usually ate out more than one to two times per week. A large percentage (88.6%) of the subjects mentioned that they ate more than half the amount of liquid in their dishes. The study participants recognized that the salt concentrations of stews, soups and noodles in their orders were high. JJamppong was recognized as the most salty among nine kinds of eating out menus, whereas mulnaengmyeon was the least. Although the recognized salt concentration of mulnaengmyeon was relatively low, this dish had the highest salinity out of nine eating out menus. Relative salinities of eating out menus were higher than absolute salinity mostly except yukgaejang. It is necessary to supply exact nutrition information and widely implement nutrition labeling. Furthermore, consumers should personally be careful to limit consuming food with high sodium levels when dining at restaurants and eat less liquid in dishes.
