The purpose of this study was to investigate the usage and perception jochung Self-administered questionnaires were collected from 445 living residents in the Daegu and Gyeongbuk areas. When purchasing jochung, respondents answered that they considered both health and taste. Recognition rate scores for jochung were in the order of 'brown rice', 'balloon flower', 'plum', and 'corn'. On the other hand, recognition rate scores for 'purple radish', 'sword bean', and 'sasa quelpaertensis' were very low. Preference and intake levels of jochung were in the order of 'plum', 'corn', 'sorghum', 'strawberry' and 'balloon flower'. On the other hand, preferences for 'purple radish', 'sword bean', and 'Hovenia dulcis' were very low. Reasons for eating jochung as a sweetener were identified as due to 'family, friend, or neighbor' (40.1%) and 'for health' (39.2%), and 54.6% ate it once or twice per week. Consumers showed low preference for different jochung used as sweeteners, and did not exactly recognize the characteristics of various jochung. Furthermore, 70.8% replied "increasing" prospects for jochung consumption. To increase consumption of jochung, there is a need for greater hygiene and safety with regards to jochung products as well as variations and improvements in quality.

The purpose of this study was to investigate awareness and knowledge on Korean traditional food among the residents in Gyeongju and Pohang area and develop and maintain it. 452 copies of a questionnaire were surveyed and analyzed statistically. The research findings were as follows. Firstly, males prefer a la Carte menu while females prefer kimchi, bab(boiled rice) juk(rice-gruel), guksu(noodles) and mandu(dumplings). Secondly, the residents favor kimchi, bulgogi and bibimbab with assorted mixtures. Thirdly, comparing the positive perception of Korean traditional food between males and females, females were more aware of traditional food and informed than males. Lastly, correspondence analysis showed that thirties prefer bab, tang(soup) and guksu while forties gu-i(roast) & jeon(panfried food) with seasonings and fifties kimchi & jang(sauce and paste). Also, high school graduates prefer eumcheong & han-gwa while college graduates bab, tang, and guksu. The residents whose monthly incomes are under W1,000,000 favor bab, tang and guksu, and those who earn over W5,000,000 per month favor kimchi & jang. The higher educational levels and incomes were, the higher qualitative factors were evaluated. Based on those findings, Korean traditional food should be generalized and more kinds of its menu should be developed.

As computers have became popular and multimedia and internet are frequently used, the volume and exchange of information have explosively increased. Therefore, more organized information system is needed for a more efficient use of information. For this reason, the importance of information design and interface design is highly recognized. This thesis is to present the user-oriented interface design prototype based on the environmental analysis of the user and information design. For this purpose, the theoretical study of information design and the principle and elements of GUI (Graphic User Interface) design is preceded. Information design is to subdivide and organize information according to its characteristic, and to systemize information structure considering the interrelationship of information. GUI design, that is interface design based on graphics, should be made in consideration of GUI elements and principle for the user's easy access of information. As it is said, much information needs to be structurized systematically and also visualized as the interface design esthetically as well as functionally. In conclusion, this study presents the effectual user-oriented interface design prototype by researching many theories of information design and GUI design and applying such theories to GUI design.

The purpose of this study was to look into Korean film criticism that started during Japanese occupation. It's specifically attempted to shed light on the development and significance of Joseon film criticism and on film movement theory as part of the history of Korean early modern film criticism. When kino-drama that could be called the start of Joseon movies was popular, enlightenment-based view of movie was rampant due to the inflow of western civilization and modernistic consciousness. Afterwards, the nature of movie itself drew a lot of attention from contemporary people in the silent picture days, and there appeared a critical trend in pursuit of artistry. Diverse criteria of criticism about reality and representation were presented, and a lot of disputes were eventually stirred up. Thus, criticism started to make a progress. A proletarian film movement theory, the so-called KAPF film campaign that was prevalent from the mid-1920s to the mid-1930s, was one of leading contemporary movie theories and took the lead in critic community. That had a great impact on the entire Joseon film circles. That took a proletarian view of movie, which was based on Bolshevik theory of Popularization and dialectic historical materialism. their criticism made a contribution to providing information on foreign movies and theories and to presenting main principles and multiple alternatives toward film organization and playing.

In recent years, since the digital camera has been popularized, so users can easily collect hundreds of photos in a single usage. Thus the managing of hundreds of digital photos is not a simple job comparing to the keeping paper photos. We know that managing and classifying a number of digital photo files are burdensome and annoying sometimes. So people hope to use an automated system for managing digital photos especially for their own purposes. The previous studies, e.g. content-based image retrieval, were focused on the clustering of general images, which it is not to be applied on digital photo clustering and classification. Recently, some specialized clustering algorithms for images clustering digital camera images were proposed. These algorithms exploit mainly the statistics of time gap between sequent photos. Though they showed a quite good result in image clustering for digital cameras, still lots of improvements are remained and unsolved. For example the current tools ignore completely the image transformation with the different focal lengths. In this paper, we present a photo considering focal length information recorded in EXIF. We propose an algorithms based on MVA(Matching Vector Analysis) for classification of digital images taken in the every day activity. Our experiment shows that our algorithm gives more than 95% success rates, which is competitive among all available methods in terms of sensitivity, specificity and flexibility.

In the past several years, many systems which adopted ring topology with high-speed unidirectional point-to-point links have emerged to overcome the limit of bus for interconnection network of clustered multiprocessor system. However, rapid increase of processor speed and performance improvement of local bus and memory system limit scalability of system with point-to-point link of standard bandwidth. Therefore, necessity to extend bandwidth is emphasized. In this paper, we adopt PANDA system as base model, which is clustering-based multiprocessor system. By simulating a model adopting commercial processor and local bus specification, we show that point-to-point link is bottleneck of system performance, and bandwidth expansion by more than 200% is needed. To expand bandwidth of interconnection network, it needs excessive design cost and time to develop new point-to-point link with doubled bandwidth. As an alternative to double bandwidth, we propose several ways to implement dual ring -simple dual ring, transaction-separated dual ring, direction-separated dual ring- by using off-the-shelf point-to-point links with IEEE standard bandwidth. We analyze pros. and cons. of each model compared with doubled-bandwidth single ring by simulation.

The purpose of this study is to examine the effect of the quality of performance on audience satisfaction, and to verify the mediating effect of service value and traditional image in this process. The subjects of this study included 211 male and female adults who experienced the Korean opera performance in Seoul, Korea in October. Collected data was used as a model of path coefficients obtained through analysis of covariance structure and hypothesis test. As a result of verification, program quality, physical environment quality, and quality of the stage performance perceived by the audience showed a statistically significant positive correlation with performance experience attributes. The path coefficient between performance attribute and service value, performance experience attribute and traditional image were also positively and statistically significant. Further, the path coefficient between performance experience and audience satisfaction showed a positive relationship. The service value and traditional image, service value and audience satisfaction, and the path coefficient between traditional image and audience satisfaction were statistically and positively significant. Finally, all hypotheses were adopted and study results confirmed the effect of service quality and experience attributes on audience satisfaction for the popularization, modernization and marketing strategy of the Korean opera. In this process, it is meaningful to verify the role and function of service value and traditional image.

As the technology in smart device is growing and Social Network Services(SNS) are becoming more common, the data which is difficult to be processed by existing RDBMS are increasing. As a result of this, NoSQL databases are getting popular as an alternative for processing massive and unstructured data generated in real time. The demand for the technique of digital investigation of NoSQL databases is increasing as the businesses introducing NoSQL database in their system are increasing, although the technique of digital investigation of databases has been researched centered on RDMBS. New techniques of digital forensic investigation are needed as NoSQL Database has no schema to normalize and the storage method differs depending on the type of database and operation environment. Research on document-based database of NoSQL has been done but it is not applicable as itself to other types of NoSQL Database. Therefore, the way of operation and data model, grasp of operation environment, collection and analysis of artifacts and recovery technique of deleted data in HBase which is a NoSQL column-based database are presented in this paper. Also the proposed technique of digital forensic investigation to HBase is verified by an experimental scenario.

With today's heightened interest in quality of life, leisure and sports activities were popular in the general public. Accordingly, the incidence of oral and maxillofacial injury are also rising. Use of a mouth protector to prevent the trauma of the oral and maxillofacial region is growing in importance, and among the mouth protector the mouthguard is the most commonly used. Mouthguard has been suggested to protect injuries by (1) preventing tooth injuries by absorbing and deflecting blows to the teeth; (2) shielding the lips, tongue, and gingival tissues from laceration; (3) preventing opposing teeth from coming into violent contact; (4) providing the mandible with resilient support, which absorbs an impact that might fracture the unsupported angle or condyle of the mandible; (5) preventing neck and cerebral brain injuries. Although mouthguard is effective for prevention of oral and maxillofacial injury, it is not widespread to athletes or general public and they are lack of awareness about the importance of mouthguard. We present the types and materials of mouthguard, things to consider when mouthguard fabrication, and the usage. This should be helpful in awareness about the importance and popularization of mouthguard.

Due to the growing popularity of mobile information technology, more people, especially in the general public, have access to computerized geospatial information systems for wayfinding tasks or urban navigation. One of the problems with the current services is that, whether the users are exploring or navigating, whether they are travelers who are totally new to a region or long-term residents who have a fair amount of regional knowledge, the same method is applied and the direction are given in the same way. However, spatial knowledge for a given urban region expands in proportion to residency. Urban navigation is highly dependent on cognitive mental images, which is developed through spatial experience and social communication. Thus, the wayfinding service for a regional community can be highly supported, using well-known regional places. This research is to develop the framework for urban navigation within a regional community. The concept of communal ontology is proposed to aid in urban regional navigation. The experimental work was implemented with case study to collect regional landmarks, develop the ontological model and represent it with formal structure. The final product of this study will provide the geographical information of a region to the other agent and be the fundamental information structure for cognitive urban regional navigation.
