Developing and managing Web applications are more complex than ever because of their growing functionalities, advancing Web technologies, increasing demands for integration with legacy applications, and changing content and structure. All these factors call for a more inclusive and comprehensive Web application design method. In response, we propose a context-based Web application design methodology that is based on several classification schemes including a Webpage classification, which is useful for identifying the information delivery mechanism and its relevant Web technology; a link classification, which reflects the semantics of various associations between pages; and a software component classification, which is helpful for pinpointing the roles of various components in the course of design. The proposed methodology also incorporates a unique Web application model comprised of a set of information clusters called compendia, each of which consists of a theme, its contextual pages, links, and components. This view is useful for modular design as well as for management of ever-changing content and structure of a Web application. The proposed methodology brings together all the three classification schemes and the Web application model to arrive at a set of both semantically cohesive and syntactically loose-coupled design artifacts.

Recent prevalence of progressive scan display such as LCD TV demands the quality improvement of existing deinterlacing techniques that convert interlaced scan images including HDTV broadcasting to progressive scan images. In this paper, we proposea motion adaptive deinterlacing technique which can be used for spatial methods, temporal methods, and the spatial-temporal methods can be used for the deinterlacing techniques selectively based on the threshold values calculated by the statistics of motion in the video contents. We also propose an improved spatial deinterlacing technique that adaptively use M-ELA and DOI based on the slant of edges that are obtained by Sobel operation. The improved picture quality of the proposed algorithm is confirmed by objective and subjective quality tests on many test image sequences.

This study aims to examine theoretical frame work of franchise restaurant, the characteristics of store manager's job and the level of their job satisfaction through an empirical investigation. Job satisfaction survey study shows that store managers consider important all work to be attended to as part of their duty with service management on top. It is also found that the majority of store managers consider their aptitude as most important job satisfaction factor and those, who are satisfied with their job content, advancement and the prospect, are more proactive in delivering qualify service and more than willing to commit themselves to their duties. Regrading demographical variables, store managers with scholarly competence and higher pay level are more likely to be satisfied with their job but married men are not satisfied with the work environment in general. Ergo, Businesses should correspond by capitalizing on those store managers content with their duty thus collecting additional information and providing opportunities to further contribute to the business. For those dissatisfied individuals, however, businesses should determine their demands and by educational training supply a motive therefore making possible the conversion of such individuals to satisfied store managers and their active participation in business management. But, as with any study, this one has a number of limitation which constraints the generalizability of the empirical findings. It has not been for long since franchise restaurants established in domestic market and has been few studies regarding this topic there. Furthermore, managers are not willing to release operation related data. Therefore, further study are urged to overcome this limitation and should examine other dimensions of job satisfaction such as relations between revenue and profit with the level of store manager's job satisfaction remain to be investigated.

With the development of cultural industries and technology, digital video marketing has grown immensely and 'Book Trailer' are now one of the main methods of promoting a title in publishing industry. The demands are growing, but the development lacks basic theoretical foundation and systematic structure. At this crucial moment, basic theoretical research on Book Trailer is necessary to establish a solid foundation for the medium to expand. In this study, I have focused on defining the basic concepts of Book Trailers and analyzing the classification of Book Trailers. In sorting the type of Book Trailers, content and formal appearance were used as standards. As a result, I was able to classify the content genre into message type, conflict type, character type using the elements of story. The formal appearance genre was classified into still photography type, motion typography type, interview type, story movie type and animation type.

PCR PET flake's market endeavors difficult situations of its oversupply and decreasing demands in South Korea. Since China banned the import of most recycled plastics, flake producers who mostly export the flakes lost their biggest market. The producers struggled to survive in the competitions with PCR PET flake from EU and 3^rd countries but it was challenging due to substandard quality and increasing cost. Attempts to improve the quality of PCR PET flake have been made but they were only an individual company's efforts. The objective of this study was to understand the market status on PCR PET flake in South Korea and to present suggestions for improving its quality. The results of the questionnaires targeted to flake producers showed that no testing methods on PCR PET flake were standardized and there were critical factors to the quality such as moisture content, contaminants, and viscosity. Case studies of US, Japan and other countries had been done especially about testing methods and 76 samples from 21 companies were tested according to those methods. Based on the results, the final factors were decided as contaminants, moisture content, alkalinity index and intrinsic viscosity. There is a plan to standardize testing methods and they could be guidelines to improve the business competitiveness of PCR PET flake in South Korea.

This study aimed to analyze the shifts in the mathematics domains of the College Scholastic Ability Test (CSAT) since its inception in 1993, with the intent of identifying improvements for the future. The goal is to provide insights for exploring the direction of assessment in Korean high school mathematics education. To this end, we focused on the test system, content area, and behavioral area within the CSAT mathematics domains. Key findings include: first, the test structure influences the assessment factors and item types, in addition to the examination time and number of items. Second, by analyzing the content area, we established a correlation between the national curriculum and assessment area, and confirmed the importance of setting the assessment area. Third, the examination of the behavioral area tended to the item-type fixation, demonstrating the necessity of the ongoing modifications in evaluation item types. Building upon these findings, we discuss the direction of an evaluation that considers the evolving demands and shifts within mathematics education.

The rapid increase of information imposes new demands of content management. The purpose of automatic audio segmentation and classification is to meet the rising need for efficient content management. With this reason, this paper proposes a high-accuracy algorithm that segments audio signals and classifies them into different classes such as speech, music, silence, and environment sounds. The proposed algorithm utilizes support vector machine (SVM) to detect audio-cuts, which are boundaries between different kinds of sounds using the parameter sequence. We then extract feature vectors that are composed of statistical data and they are used as an input of fuzzy c-means (FCM) classifier to partition audio-segments into different classes. To evaluate segmentation and classification performance of the proposed SVM-FCM based algorithm, we consider precision and recall rates for segmentation and classification accuracy for classification. Furthermore, we compare the proposed algorithm with other methods including binary and FCM classifiers in terms of segmentation performance. Experimental results show that the proposed algorithm outperforms other methods in both precision and recall rates.

With the development of online education due to COVID-19, the EduTech market, which combines new technologies such as AI and AR/VR in education is rapidly growing. In addition, the children's industry is steadily growing despite the decreasing birth rate every year as more and more families with one child per household are investing in their children. However, supply of contents to EduTech market is slow compared to demands that are increasing. Therefore, the purpose of this paper is to help solve these problems by developing and supporting AR kids contents with convenience, practicality, and efficiency using AR technology. AR content for supporting vocabulary learning for infants is not just an end to watching and listening, but an observation-driven model that can manipulate content directly, which attracts children's interest and helps children learn words. This paper is intended for infants from 15 months to 36 months old when full-fledged language development occurs.

Background: Safety data sheets (SDSs) are hazard communication materials that accompany chemicals/hazardous products in the workplace. Many SDSs contain dense, technical text, which places considerable comprehension demands on workers, especially those with lower literacy skills. The goal of this study was to assess SDSs for readability, comprehensibility, and suitability (i.e., fit to the target audience). Methods: The Suitability Assessment of Materials (SAM) tool assessed SDSs for suitability and readability. We then amended the SAM tool to further assess SDSs for comprehensibility factors. Both the original and amended SAM tool were used to score 45 randomly selected SDSs for content, literacy demand, graphics, and layout/typography. Results: SDSs performed poorly in terms of readability, suitability, and comprehensibility. The mean readability scores were Flesch-Kincaid Grade Level (9.6), Gunning Fog index (11.0), Coleman-Liau index (13.7), and Simple Measure of Gobbledygook index (10.7), all above the recommended reading level. The original SAM graded SDSs as "not suitable" for suitability and readability. When the amended SAM was used, the mean total SAM score increased, but the SDSs were still considered "not suitable" when adding comprehensibility considerations. The amended SAM tool better identified content-related issues specific to SDSs that make it difficult for a reader to understand the material. Conclusions: In terms of readability, comprehensibility, and suitability, SDSs perform poorly in their primary role as a hazard communication tool, therefore, putting workers at risk. The amended SAM tool could be used when writing SDSs to ensure that the information is more easily understandable for all audiences.

This study aims to propose a set of guidelines for the development of university librarians' continuing education program. It examines previous academic literature regarding such programs both in Korea and overseas, as well as the present condition and demands of Korean university librarians. A survey was conducted by systematically sampling 33.3% of all university librarians nationwide and asking about their experiences with the existing continuing education program(e. g., general satisfaction level, program topics, program administration, evaluation methods, outreach methods, reasons for participation). The survey results show that the participants: (1) had a relatively low satisfaction level; (2) strongly demand programs focusing on library promotion, management of information resources and knowledge content, and skills to adiust to the rapidly changing library environment; (3) prefer a week-long course focused on specialized subjects and skill development; and (4) cite more specialized education content, the establishment of a support system, and diversified education levels as factors that would further their interest in the continuing education program.
