  • It is required to estimate color reproduction accurately in printing. Because printing technology has been developing, and most people want to see the best color reproduction. Therefore many color reproduction methods, such as Neural Network, LUT(Look Up Table) have been proposed for a long time. However, these methods are required to measure a lot of samples of printing. In this paper, we propose a new method that prediction of color reproduction based on compensated Neugebauer model for dotgain. This method was significant to increase an accuracy of color prediction with simple process.

  • The infringement of the copyright is a problem by the distribution of digital contents copied illegally. The digital watermark is expected as a thing preventing unjust copying by burying information in digital data such as image, animation, the sound, TV, radio and movies. [1] [2]But a noise is included in a digital watermark reproduction image. So there is the case that the certification of the reproduction image has difficulty with. If a computer cannot recognize the information reproduced from digital watermarking, the information does not have a meaning. This paper aimed at improvement of the proof of a digital-watermarking reproduction image. And it is verified whether the difference of the form of a character affects the degree of correlation.

  • Purpose: As of July 31, there were 14,336 confirmed cases of COVID-19 in South Korea, including 301 deaths. Since the daily confirmed number of cases hit 909 on February 29, the spread of the disease had gradually decreased due to the active implementation of preventive control interventions, and the daily confirmed number had finally recorded a single digit on April 19. Since May, however, the disease has re-emerged and retaining after June. In order to eradicate the disease, it is necessary to suggest suitable forward preventive strategies by predicting future infectivity of the disease based on the cases so far. Therefore, in this study, we aim to evaluate the transmission potential of the disease in early phases by estimating basic reproduction number and assess the preventive control measures through effective reproduction number. Methods: We used publicly available cases and deaths data regarding COVID-19 in South Korea as of July 31. Using ensemble model integrated stochastic linear birth model and deterministic linear growth model, the basic reproduction number and the effective reproduction number were estimated. Results: Estimated basic reproduction number is 3.1 (95% CI: 3.0-3.2). Effective reproduction number was the highest with 7 on February 15, decreased as of April 20. Since then, the value is gradually increased to more than unity. Conclusion: Preventive policy such as wearing a mask and physical distancing campaigns in the early phase of the outbreak was fairly implemented. However, the infection potential increased due to weakening government policy on May 6. Our results suggest that it seems necessary to implement a stronger policy than the current level.

  • Measurement of noise is not only to know the information of acoustic pressure but to assess human response for noise. Provided that want to find human response for transportation noise, we will have to reproduce the measured noise. The method of reproduction is largely divided into monaural and binaural reproduction techniques. Human fundamentally hears sound through both ears, which is binaural hearing. And binaural technique includes the more information of physical phenomena like acoustical reflection and deflection. So, binaural reproduction is more suitable for assessment of the psychoacoustical and physiological response for transportation noise exposures.

  • The reproduction of animals is a way to maintain their species and demands a large amount of energy. The golden hamsters are seasonal breeders whose reproductive activities are regulated by photoperiod (length of day time in a day). The photic information received is transported to the pineal gland via many steps. Melatonin produced by the pineal gland affects the reproductive neuroendocrine system to manage reproductive activities. The major regulator neurons, secreting gonadotropin-releasing hormone, integrate all kinds of information to govern the reproductive frame hypothalamuspituitary-gonad axis. The elements impinging on the neurons are recently outspread. Thus the present review is to briefly survey the elements discovered newly and subjected to the active research realm and their correlations, focusing on the regulation of reproduction in mainly male golden hamsters as a representative animal.

  • A blog has significant effect as a new online medium and as a tool to share information with its powerful networking function. Blogs are established based on personal experience and their impact is stronger than conventional media in terms of informativeness, credibility and interactivity. Such characteristics of blogs lead to blog commitment (a phenomenon that has behavioral consequences) that eventually influences consumer fashion purchase behavior. The more a consumer is interested in fashion and seeks diverse information from a wide range of media, the more personally committed they become to certain blogs; in addition, they will also post the results of their fashion product purchases on their blog to further create and reproduce information. This research discovers how blog commitment affects fashion product purchase behavior and information reproduction activity among consumers as well as explores the impact of blog characteristics and information variety seeking by individual consumers on these factors. The data was collected from 428 adults who purchased a fashion product based on information they found on a blog. The results are as follows. First, blog characteristics are composed of accessibility, interactivity, credibility of the information, and informativeness. Second, in terms of the blog commitment, informativeness, credibility, and consumer information diversification (respectively), turned out to have positive effects; in addition, accessibility and credibility had positive effects for corporate blogs. The comparison between private and corporate blogs showed that consumers tend to be more committed to private blogs. Third, in terms of the brand attitude, private/corporate blog commitment, credibility, and consumer information diversification (respectively) had a positive influence. Fourth, blog characteristics and consumer information diversification led consumers (through private/corporate blog commitment) to form a favorable attitude towards the brand and purchase products that resulted in information reproduction of the purchased product.

  • Rapid progress in epigenetic studies has resulted in genome wide information of genetic functions, other than DNA sequence information. However, insufficient understanding and unclear research direction in epigenetics has failed to attract many researchers. Here, we review the sexual reproduction processes that are particularly related to epigenetics in plants. We aim to elucidate the roles of epigenetic information and molecular mechanisms involved in the complex sexual reproduction process of plants, and examine their biological significance.

  • In this paper, a new technique for color reproduction based on color variation characteristics of digital camera under a dim light condition is proposed. Generally, photographers should adjust a camera exposure properly for obtaining an image with real color tone of subjects. Thus, in case of taking a picture under a dim light condition, the exposure time of a camera has to be relatively longer than the one under a bright light condition. Although images with real color tone of the subject are obtained, the images may get blurred due to the shaky hands of photographer holding the camera. In order to avoid the blur effect, an input image is captured from a camera set as a short exposure time under a dim light condition. Then we propose a method to reproduce color tone of the dim input image. To this end, color variation characteristics which represent color variations of a digital camera are first extracted by analyzing the Macbeth color checker images taken under various exposure values. Then, a color reproduction is performed by an estimation based on the color variation characteristics. Experimental results have shown that the proposed method has achieved better performance of color reproduction, compared with existing methods.
