Currently, the black-white QR (Quick Response) codes have been used widely in consumer advertising fields and the study of color QR codes have received a growing demand because of much higher data encoding capacity. Color QR codes can be reproduced by the printing and scanning processes, however, these encounter colors distortion caused by insufficient lighting, low resolution of camera and geometric deformation during the capturing processes. In order to overcome these problems, this paper proposes an efficient decoding algorithm for color QR codes with inserted patterns, which are dealt with conventional studies. These are evaluated in view of the recognition rate under different noise conditions, for example, Gaussian noises/blurring and geometric deformation. Experimental results demonstrate that the color QR codes with simple pattern can resist the distortion of Gaussian noises/blurrings.

Background: Recently clinical trials have expanded extensively in Korea; thus, ensuring the rights of subjects participating in clinical trials is imperative. Accordingly, national regulations on subject recruitment advertisement were enforced from October 25, 2018. In this study, the effect of this regulation was evaluated by analyzing the difference in the provision of information before and after enforcement of the regulation. Methods: Recruitment advertisements for clinical trial subjects 3 years before and after enforcement of the regulation were collated by the significance sampling approach. Print-based (newspapers, buses, and subways) and web-based (clinical trial center websites and online platforms) materials for recruitment in clinical trials of phase 1 to 4 for investigational drugs, medical devices, and oriental medicine were considered. Chi-square tests were conducted for inter-group comparisons. SPSS version 26 was employed for statistical analyses. Results: A total of 137 advertisements were collected comprising 60 pre- and 77 post-regulation enforcement. The overall rate of delivery of critical information in advertisements increased significantly from 47.5% before regulation to 93.2% after regulation enforcement. Particularly, details on expected adverse events augmented significantly (p<0.001). Benefits from participation in clinical trial reduced significantly from 88.3% to 70.1% (p<0.05). As the information provision amplified, the inclusion of professional terms increased. Conclusions: Enforcement of regulations has led to a surge in the amount of information and challenging terms contained in advertisements for recruiting subjects. Therefore, additional efforts are required by subjects to completely understand the information provided in the advertisements.

Untact order payment has become a new normal since the COVID-19. BLE beacon is a technology that supports low-power wireless communication within 70 meters without Bluetooth pairing and is specialized for indoor positioning. Therefore, it is suitable for building and providing O2O services beyond B2C and B2B services. However, beacons have a lower utilization rate because they have fewer platforms than wifi that support long-distance wireless communication. Therefore, this paper aims to provide more convenient non-face-to-face related services than before by designing and proposing an O2O service platform using BLE beacons. When scanning beacons, not only does it receive advertising data that beacons have, but it also ensures that the actual distance between the user's terminal and beacons is accurately calculated. Through accurate location, the O2O service platform will be able to provide users with store information, such as coupons and discounts, museum exhibits, and traffic information at the right time.

The impact of TV Drama success on TV Rating and the channel promotion effectiveness is very high. The cultural and business impact has been also demonstrated through the Korean Wave. Therefore, the early prediction of the blockbuster success of TV Drama is very important from the strategic perspective of the media industry. Previous studies have tried to predict the audience ratings and success of drama based on various methods. However, most of the studies have made simple predictions using intuitive methods such as the main actor and time zone. These studies have limitations in predicting. In this study, we propose a model for predicting the popularity of drama by analyzing the customer's viewing pattern based on various theories. This is not only a theoretical contribution but also has a contribution from the practical point of view that can be used in actual broadcasting companies. In this study, we collected data of 280 TV mini-series dramas, broadcasted over the terrestrial channels for 10 years from 2003 to 2012. From the data, we selected the most highly ranked and the least highly ranked 45 TV drama and analyzed the viewing patterns of them by 11-step. The various assumptions and conditions for modeling are based on existing studies, or by the opinions of actual broadcasters and by data mining techniques. Then, we developed a prediction model by measuring the viewing-time distance (difference) using Euclidean and Correlation method, which is termed in our study similarity (the sum of distance). Through the similarity measure, we predicted the success of dramas from the viewer's initial viewing-time pattern distribution using 1~5 episodes. In order to confirm that the model is shaken according to the measurement method, various distance measurement methods were applied and the model was checked for its dryness. And when the model was established, we could make a more predictive model using a grid search. Furthermore, we classified the viewers who had watched TV drama more than 70% of the total airtime as the "passionate viewer" when a new drama is broadcasted. Then we compared the drama's passionate viewer percentage the most highly ranked and the least highly ranked dramas. So that we can determine the possibility of blockbuster TV mini-series. We find that the initial viewing-time pattern is the key factor for the prediction of blockbuster dramas. From our model, block-buster dramas were correctly classified with the 75.47% accuracy with the initial viewing-time pattern analysis. This paper shows high prediction rate while suggesting audience rating method different from existing ones. Currently, broadcasters rely heavily on some famous actors called so-called star systems, so they are in more severe competition than ever due to rising production costs of broadcasting programs, long-term recession, aggressive investment in comprehensive programming channels and large corporations. Everyone is in a financially difficult situation. The basic revenue model of these broadcasters is advertising, and the execution of advertising is based on audience rating as a basic index. In the drama, there is uncertainty in the drama market that it is difficult to forecast the demand due to the nature of the commodity, while the drama market has a high financial contribution in the success of various contents of the broadcasting company. Therefore, to minimize the risk of failure. Thus, by analyzing the distribution of the first-time viewing time, it can be a practical help to establish a response strategy (organization/ marketing/story change, etc.) of the related company. Also, in this paper, we found that the behavior of the audience is crucial to the success of the program. In this paper, we define TV viewing as a measure of how enthusiastically watching TV is watched. We can predict the success of the program successfully by calculating the loyalty of the customer with the hot blood. This way of calculating loyalty can also be used to calculate loyalty to various platforms. It can also be used for marketing programs such as highlights, script previews, making movies, characters, games, and other marketing projects.

This study was intended to investigate the alcohol drinking characteristics, Makgeolli drinking behavior, and perception of Makgeolli focusing on the Chinese students studying in Korea. 550 copies of self-administrated questionnaire for a survey were distributed from May 2nd to June 30th, 2012, and then 461 copies were adopted for the analyses. The drinking frequency and drinking amount at a time increased as the length of stay in Korea and monthly pocket money increased, and Makgeolli was second preferred, following beer. 97.5% of the students experienced drinking Makgeolli, the drinking rate and drinking amount of Makgeolli increased with the length of stay in Korea, and they mostly drank at restaurants and bars. Common motivations for drinking Makgeolli were taste and atmosphere while drinking it, and bad taste and headache were the most common reasons for disliking Makgeolli. The awareness of commercial Makgeolli types was low, and for the price and health promoting effects of Makgeolli, 92.4% and 85.8% of the students replied positively, respectively. These results suggest that the development of high quality Makgeolli adapted to the tastes of Chinese and relieving hangover, and advertising the health benefits would promote Makgeolli consumption in Chinese market.

The Korea Expressway Corporation announced that road casualties on expressways in 2016 were 262 deaths, a 24% decrease compared to 343 deaths in 2015, thanks to the expansion of rest areas for sleepy drivers. And the installation of large-sized banners containing strong messages such as "dozing while driving means your death" helped to reduce the casualty caused by driving while drowsy by 35% compared to that in 2015. Accordingly, this study tried to analyze the impact of public advertisements designed to prohibit dozing while driving on expressways upon drivers, and to present a direction for improvement of such public advertisements in the future. Based on case studies and library researches, the study contemplated the effects of public advertisements on expressways at home and abroad. It was confirmed that the accident rate has been higher on straight roads than on curved roads and that the framing of negative messages using provocative images or slogans on traffic accidents has been considerably effective. In conclusion, if the installation of outdoor billboards for public advertisements at rest areas for sleepy drivers is institutionalized and the systematic provision of information by road section inside and outside of vehicles via Variable Message Sign (VMS) services on expressways, outdoor billboards, or navigation services (including smartphones) is available, it would be possible to maximize the effect of the public advertisements.

The purpose of this study was to investigate changes to visual expressions in apartment sales ads in newspapers since the 2000s. For this purpose, the study compared and examined advertisements in 2010~2018 for their content. Apartment sales ads in the newspapers of Busan were analyzed according to the types of visual expressions and advertisement models. The brands(national and local brands) were categorized according to the types of visual expressions(copywriting-centric, visual-centric, and mixed ones) and whether an advertisement model was used or not(used and not used). The findings show that visual-centric ads were most used in apartment sales ads by national brands in 2010~2011 and recorded a higher usage rate by local brands during the same period. In 2017~2018, mixed forms of visual expressions were used more in the ads. The percentage of visual-centric ads made a considerable decrease among local brands. As for the use of advertisement models, most of the brands used one in 2010~2011, but advertisement models almost disappeared in apartment sales ads in 2017~2018. These differences were more prominent among local brands. The findings indicate that there were differences in expressive strategies in apartment sales ads among brands. The findings are expected to provide useful practical implications for the visual expression strategies of apartment sales ads.
