The purpose of this study is to analyze the educational effect of learning mentoring conducted by EBS for elementary and middle school students, the changes in self-directed learning skills, emotional stability and learning effect were analyzed for 425 students who participated in the EBS learning mentoring. As a result, There was no statistically significant difference in the educational effect according to the mentoring service period, method, and frequency, and there was a statistically significant difference in self-directed learning ability according to the mentoring time. As a result of analyzing the effect of the perception of the mentor on the educational effect, the more positive the mentor and the more positive the mentor role, the higher the self-directed learning ability and emotional stability. As for the learning effect, mentoring satisfaction had the greatest influence on the learning effect of Korean, English, and mathematics. The mentor role was affecting the Korean language and mathematics. Therefore, in order to reduce the learning gap of underprivileged students in the distance learning situation, the EBS learning mentoring project should be continuously promoted, and the mentoring period and the number of students and teachers participating in mentoring should be significantly increased.

The usual way used by electric power stations to deliver high levels of generated power is via 6.6kV XLPE (or CV) cables. Depending on the manufacturing technique, installation environment, and usage conditions, the deterioration processes of the power cables start from the instant of operation. Cable junctions may break down in three years from the start of operation due to the manufacturing or construction defects. Otherwise they should be in good working order for 20-30 years. When the cable system (the cable itself and cable junctions combined) deteriorates, fire accidents happen due to the dielectric breakdowns. We have invented a device to monitor the deteriorating status of cables at Korean Western Power Co. Ltd. located in Taean, Chungcheongnam-do province. In this paper, we introduce the device hardware. Using the device, we have measured the insulation resistance and humidity in the sheath of the cables. We present, in analysed results, the effect of humidity on insulation resistance in cable sheaths.

The demand for electric power is increasing every year. All facilities operating at power stations and all facilities used in transmitting high volumes of electric power are therefore expected to operate with a high degree of reliability. 6.6 kV XLPE 100 SQ 1C cables are used to deliver high levels of generated electric power. Depending on the method of manufacture, installation environment, and usage conditions, the deterioration processes of power cables start from the instant of operation. Cable junctions may break down in three years from the start of operation due to manufacturing or construction defects. We have invented the first device in Korea to monitor the status of live cables and installed these at Korea Western Power Co., Ltd.. We have set the criteria to determine deterioration status and specified the degree of deterioration at which one should replace the cables. In this paper, we present the effect of insulation layer and sheath on the insulation resistance status in cables.

The purpose of this study is to analyze the structural relationship between politicians' YouTube information service quality, politician's image and trust, and voters' social and political participation intentions. To investigate this, 306 voters were sampled through an online survey. The quality factors of the politician's YouTube information service were found to have a positive effect on the image of a politician. Among them, timeliness and reliability had a positive effect on the trust of politicians, but playfulness did not. Both the image and trust of politicians through YouTube were found to have a positive effect on voters' intention to participate in society and politics. As a result of examining the indirect effect, it was found that the image of a politician had an indirect effect on the quality of information service and the intention to participate in society and politics. This study is significant in revealing that the fact that the image and trust of politicians is a major variable that appeals to citizens' social and political participation is also applicable to YouTube.

Diabetes is chronic disease that is rapidly increasing in prevalence around the world, and mortality from complications continues to rise. This has made blood glucose management a critical challenge for modern society. The main methods used to manage blood glucose are diet, exercise, and medication. Among these, diet is one of the fundamental foundations of blood glucose management, avoiding foods that cause high blood glucose and minimizing blood glucose fluctuations, and is more accessible to people with diabetes as well as the general population. Currently, several platforms, both domestic and international, offer meal planning services, but this is mainly done by users or professional coaches. Accordingly, this paper implements an accurate Kcal calculation model based on DNN and presents a series of dietary algorithms for blood glucose management based on this.

Broadcasting programs are provided to various media such as Internet replay, OTT, and IPTV services as well as self-broadcasting. In this case, it is very important to provide keywords for search that represent the characteristics of the content well. Broadcasters mainly use the method of manually entering key keywords in the production process and the archive process. This method is insufficient in terms of quantity to secure core metadata, and also reveals limitations in recommending and using content in other media services. This study supports securing a large number of metadata by utilizing closed caption data pre-archived through the DTV closed captioning server developed in EBS. First, core metadata was automatically extracted by applying Google's natural language AI technology. The next step is to propose a method of finding core metadata by reflecting priorities and content characteristics as core research contents. As a technology to obtain differentiated metadata weights, the importance was classified by applying the TF-IDF calculation method. Successful weight data were obtained as a result of the experiment. The string metadata obtained by this study, when combined with future string similarity measurement studies, becomes the basis for securing sophisticated content recommendation metadata from content services provided to other media.

This paper analyzed the so-called 'Honey Butter Almond case', which became a hot topic by showing that the packaging design of a product can be distinguished as a recognizable trademark, not just a pattern. In the judgment, the issue was whether the discrimination power of the registered trademark and the similarity to the previously used trademark. First of all, with respect to the discrimination power of the registered trademark, the court said that the package front figure functions as an identification mark of the source, as long as the specificity of the expression method and overall composition are distinct from the commonly used. And the court said that it is difficult to say that the dominant impression is similar to the previously used trademark (the snack 'Honey Butter Chip') in terms of its name and idea. This case is acknowledging the function of the packaging design as a product label, and also acknowledging it can acquire identification as a distinctive trademark through the uniqueness of its composition and expression method.
