  • License plate recognition plays a key role in intelligent transportation systems. Therefore, it is a very important process to efficiently detect the number and character areas. In this paper, we propose a method to effectively detect license plate number area by applying deep learning and semantic image segmentation algorithm. The proposed method is an algorithm that detects number and text areas directly from the license plate without preprocessing such as pixel projection. The license plate image was acquired from a fixed camera installed on the road, and was used in various real situations taking into account both weather and lighting changes. The input images was normalized to reduce the color change, and the deep learning neural networks used in the experiment were Vgg16, Vgg19, ResNet18, and ResNet50. To examine the performance of the proposed method, we experimented with 500 license plate images. 300 sheets were used for learning and 200 sheets were used for testing. As a result of computer simulation, it was the best when using ResNet50, and 95.77% accuracy was obtained.

  • This study wanted to analyze the types of recognition of messages expressed in clothing for women in their 20s who wear a lot of clothing and fashion products with text. It was intended to provide basic data necessary for the production of typography clothing and fashion products by considering the subjective evaluation of how women in their 20s type the characters expressed in fashion and the characteristics of each type. This study was conducted with the Q method, and the QUANL pc program was used for analysis. Type I thought that letters were a design element and fashion, and the characters expressed in clothes were recognized as images. Type 2 thought it was important that the characters expressed in the clothing were recognized as messages, and that the characters had social messages and period reflections. Type 3 preferred that letters be combined with casual clothes and valued the formability of the characters. Type 4 preferred characters to represent brands and liked to be placed in large positions. In the future, it is thought that additional research by various age groups and genders and detailed research should be conducted to identify differences in font, color, and sentence length.

  • Purpose: This study explored the suitability of interventions for medication interruption and intervention preferences. Methods: Two rounds of Delphi surveys were conducted with 18 expert panels comprising staff (or charge) nurses, nursing managers, and Quality Improvement (QI) team nurses working in a tertiary general hospital. For 47 situations involving the location of interruption, medication step, and source of interruption, the suitability of three interventions (no-interruption zone, medication safety vest, and education) was evaluated using a 5-point scale. Results: A total of 51 interventions for each situation were found appropriate by satisfying the degree of convergence and consensus. Patients or caregivers, peer nurses, doctors, telephones, and call bells were sources of interruption and were identified as appropriate for the application of interventions. 'Responding to requests and inquiries' by patients or caregivers showed high overall suitability. The nurses' preferred color for the intervention design (no-interruption zone, medication safety vest) is blue text on a yellow background. The priority groups for education related to medication interruptions were patients or caregivers, nurses, and non-nursing staff, in that order. Conclusion: Effective implementation of tailored intervention strategies that consider the specific characteristics of medication interruptions is crucial for mitigating interruptions and enhancing patient safety. Comprehensive educational programs aimed at reducing medication interruptions by improving awareness are necessary. Moreover, future research should evaluate these strategies in clinical settings to ensure their effectiveness in enhancing patient safety.

  • This study analyzed the degree of influence of measurement and improvement of customer satisfaction level targeting kiosk users. In modern times, due to the development of technology and the improvement of the online environment, the probability that simple labor tasks will disappear after 10 years is close to 90%. Even in domestic research, it is predicted that 'simple labor jobs' will disappear due to the influence of advanced technology with a probability of about 36%. there is. In particular, as the demand for non-face-to-face services increases due to the Corona 19 virus, which is recently spreading globally, the trend of introducing kiosks has accelerated, and the global market will grow to 83.5 billion won in 2021, showing an average annual growth rate of 8.9%. there is. However, due to the unmanned nature of these kiosks, some consumers still have difficulties in using them, and consumers who are not familiar with the use of these technologies have a negative attitude towards service co-producers due to rejection of non-face-to-face services and anxiety about service errors. Lack of understanding leads to role conflicts between sales clerks and consumers, or inequality is being created in terms of service provision and generations accustomed to using technology. In addition, since kiosk is a representative technology-based self-service industry, if the user feels uncomfortable or requires additional labor, the overall service value decreases and the growth of the kiosk industry itself can be suppressed. It is important. Therefore, interviews were conducted on the main points of direct use with actual users centered on display color scheme, text size, device design, device size, internal UI (interface), amount of information, recognition sensor (barcode, NFC, etc.), Display brightness, self-event, and reaction speed items were extracted. Afterwards, using the questionnaire, the Kano model quality attribute classification of each expected evaluation item was carried out, and Timko's customer satisfaction coefficient, which can be calculated with accurate numerical values The PCSI Index analysis was additionally performed to determine the improvement priorities by finally classifying the improvement impact of the kiosk expected evaluation items through research. As a result, the impact of improvement appears in the order of internal UI (interface), text size, recognition sensor (barcode, NFC, etc.), reaction speed, self-event, display brightness, amount of information, device size, device design, and display color scheme. Through this, we intend to contribute to a comprehensive comparison of kiosk-based research in each field and to set the direction for improvement in the venture industry.

  • Film color is equivalent to other elements of film, including narrative, and has a textual meaning according to the identity of expression. In general, red has a function of focusing attention, and the meaning derived from it is diffused. In the interaction of text and context, the function of concentration and the meaning of diffusion can be presented. The concept of concentration and diffusion is shaped by the relationship between independent colors, colors and other cinematic elements, and interactions between colors. In order to confirm this, this study analyzes a series of popular Korean films, how film colors interact, and in particular, the concentration function of red and the meaning of proliferation. The results of this study are as follows. First, in Korean popular films, at its most basic, red symbolizes a nation, a people, and a nation. The red of nationalism surrounding ethnicity, nationality and country visualizes ideology and conflict. The purpose of an individual or group, the relationship between the offender and the victim is mediated through red. The flag, the name tag, the costume appearing in the film are red. This can be seen in films such as Train to Busan, Assassination, Masquerade, Miracle in Cell No.7, Brotherhood of War, Northern Limit Line, Joint Security Area, Welcome to Dongmakgol, and May 18. Second, the red color attached to the female body fixes or strengthens socio-cultural sexuality and gender. The examples are films like Ode to My Father, The Thieves, The Host, Purpose Of Love, Sunny, Like A Virgin, Forbidden Quest, Untold Scandal, Bewitching Attraction, and Ssanghwajeom. Third, the blood red in Korean films is a visual device that directs magical horror, anger, and asceticism. Such films include The Neighbors, Bunshinsaba, R-Point, A Tale Of Two Sisters, Whispering Corridors, The Uninvited, Thirst, SECTOR 7, Asura:The City of Madness, The Tiger, Veteran, and so on. Fourth, red of tears constitutes the specific emotions such as a beautiful desire and a brilliant tragedy in films like King and The Clown, Oldboy, Memories of Murder, 26 Years, The Attorney, Unbowed, Sympathy For Lady Vengeance, Happy End, Punch, Calling, The Yellow Sea, and He's on Duty.

  • In genetic and molecular breeding studies of plants, researchers need to design various kinds of primers based on their research purposes. So far many kinds of web- or script-based non-commercial programs for primer design are available. Because most of them do not include user interface for multipurpose usage including gene structure prediction and direct target selection on sequences, it has been a laborious work to design primers targeting on the exon or intron regions of interesting genes. Here we report a primer designing graphic user interface program, Pickprimer, that includes gene structure prediction and primer design modules by combining source codes of the Spidey and Primer3 programs. This program provides simple graphic user interface to input sequences and design primers. Genomic sequence and mRNA or coding sequence of genes can be copy and pasted or input as fasta or text files. Based on alignment of the input sequences using the Spidey module, a putative gene structure is graphically visualized along with exon-intron sequences of color codes. Primer design can be easily performed by dragging mouse on the displayed sequences or input primer targeting position with desirable values of primers. The output of designed primers with detailed information is provided by the Primer3 module. PCR evaluation of 24 selected primer sets successfully amplified single amplicons from six Brassica rapa cultivars. The Pickprimer will be a convenient tool for genetic and molecular breeding studies of plants.

  • In general LPR(License Plate Recognition) in outdoor image is not so simple differently from in the image captured from manmade environment, because of geometric shape distortion and large illumination changes. this paper proposes three techniques for LPR in outdoor images captured from CCTV. At first, a serially connected multi-stage Adaboost LP detector is proposed, in which different complementary features are used. In the proposed detector the performance is increased by the Haar-like Adaboost LP detector consecutively connected to the MB-LBP based one in serial manner. In addition the technique is proposed that makes image processing easy by the prior determination of LP type, after correction of geometric distortion of LP image. The technique is more efficient than the processing the whole LP image without knowledge of LP type in that we can take the appropriate color to gray conversion, accurate location for separation of text/numeric character sub-images, and proper parameter selection for image processing. In the proposed technique we use DBN(Deep Belief Network) to achieve a robust character recognition against stroke loss and geometric distortion like slant due to the incomplete image processing.

  • This study proposes IMToon(IMage-based carToon) which is an image-based cartoon authoring system using an image processing algorithm. The proposed IMToon allows general users to easily and efficiently produce frames comprising cartoons based on image. The authoring system is designed largely with two functions: cartoon effector and interactive story editor. Cartoon effector automatically converts input images into a cartoon-style image, which consists of image-based cartoon shading and outline drawing steps. Image-based cartoon shading is to receive images of the desired scenes from users, separate brightness information from the color model of the input images, simplify them to a shading range of desired steps, and recreate them as cartoon-style images. Then, the final cartoon style images are created through the outline drawing step in which the outlines of the shaded images are applied through edge detection. Interactive story editor is used to enter text balloons and subtitles in a dialog structure to create one scene of the completed cartoon that delivers a story such as web-toon or comic book. In addition, the cartoon effector, which converts images into cartoon style, is expanded to videos so that it can be applied to videos as well as still images. Finally, various experiments are conducted to verify the possibility of easy and efficient production of cartoons that users want based on images with the proposed IMToon system.
