The purpose of this study was to investigate consumers' perceptions on monosodium L-glutamate (MSG) in social media. Data were collected from Naver blogs and Naver web communities (Korean representative portal web-site), and media reports including comment sections on a Yonhap news website (Korean largest news agency). The results from Naver blogs and Naver web communities showed that it was primarily mentioned MSG-use restaurant reviews, 'MSG-no added' products, its safety, and methods of reducing MSG in food. When TV shows on current affairs, newspaper, or TV news reported uses and side effects of MSG, search volume for MSG has increased in both PC and mobile search engines. Search volume has increased especially when TV shows on current affairs reported it. There are more periods with increased search volume for Mobile than PC. Also, it was mainly commented about safety of MSG, criticism of low-quality foods, abuse of MSG, and distrust of government below the news on the Yonhap news site. The label of MSG-no added products in market emphasized "MSG-free" even though it is allocated as an acceptable daily intake (ADI) not-specified by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). When consumers search for MSG (monosodium L-glutamate) or purchase food on market, they might perceive that 'MSG-no added' products are better. Competent authorities, offices of education and local government provide guidelines based on no added MSG principle and these policies might affect consumers' perceptions. TV program or news program could be a powerful and effective consumer communication channel about MSG through Mobile rather than PC. Therefore media including TV should report item on monosodium L-glutamate with responsibility and information based on scientific background for consumers to get reliable information.

Users in social media post various types of opinions such as product reviews and movie reviews. It is a common trend that customers get assistance from the opinions in making their decisions. However, as opinion usage grows, distorted feedbacks also have increased. For example, exaggerated positive opinions are posted for promoting target products. So are negative opinions which are far from common evaluations. Finding these biased opinions becomes important to keep social media reliable. Techniques of opinion mining (or sentiment analysis) have been developed to determine sentiment polarity of opinionated documents. These techniques can be utilized for finding the biased opinions. However, the previous techniques have some drawback. They categorize the text into only positive and negative, and they also need a large amount of training data to build the classifier. In this paper, we propose methods for discovering the biased opinions which are skewed from the overall common opinions. The methods are based on angle based outlier detection and personalized PageRank, which can be applied without training data. We analyze the performance of the proposed techniques by presenting experimental results on a movie review dataset.

This study aimed to assess the level of intention to tampon use among female university students and to identify factors influencing intention to tampon use. The participants were 140 female university students. Data collection was performed through an online survey using chi-squared test, spearman's correlation coefficients, and multivariable logistic regression analysis from March 13 to March 30, 2024. In this study, it was found that 63.6% of female university students had an intention to use tampon and factors influencing intention to tampon use were marital status, length of menstruation, and prior experience with tampon use. Specifically, participants who were 'unmarried', 'had menstruation lasting 5 days or shorter', and 'had previous experience with tampon use' demonstrated a higher intention to use tampons. Therefore, it is necessary to continuously monitor the changing patterns of women's menstrual product usage and intention, identify influencing factors, and establish educational and promotional strategies to provide information on the characteristics and usage of menstrual products, enabling women to choose the best products suited to their menstrual needs.

The purpose of this study was to prepare basic data for improving school library information service by investigating the information usage behavior of specialized high school students. Preferred information sources for each situation requiring information and the level of solving information problems using information sources were investigated, and difference analysis was conducted by department and grade. As a result of the survey, the percentage of students who preferred Internet portal services, personal information sources (teachers, friends, parents), and social media was high, while the percentage of students who preferred traditional print information sources and mass media was very low. The average score of the information problem solving level was 3.55, and the problem solving level in the areas of employment and career/admission was relatively low. Preferred sources of information were similar regardless of grade and department, and the difference between departments in information problem solving level was not statistically significant, but the difference between grades was statistically significant. In addition, there is an academic contribution in this field that specific examples of youth information use behavior have been added. Based on the results of the study, librarians should make efforts to verify the reliability of Internet portal site information, improve and promote library information sources, and expand library use education. In future studies, it was suggested to develop customized information services.

During the COVID-19 period, public libraries produced and provided a variety of online contents to users as an alternative to offline services. The purpose of this study was to analyze the overall management of online contents in public libraries in the post COVID-19 period and to provide a methodological basis for improving online contents management. This study surveyed the overall current state of online content management in 305 public libraries in terms of production, services, and preservation. We also analyzed the librarian's perception of the online contents management process. As a result of the analysis even after the COVID-19 period, public libraries are efficiently producing and providing online contents and are actively providing this through the library website and social media. In addition, librarians recognized that online contents produced by public libraries are valuable as library resources and predicted that the online content would be produced more in the future. Also, they faced difficulties in production and management due to a lack of professional capabilities and extra workload, but they have recognized the high need for online contents management. Online contents is leading a paradigm shift in public library services. Therefore, attention and effort to activate online content is no longer an option but a necessity.
