        This study aimed to address the increasing demand for technologies preventing mushroom fly damage. By monitoring the annual occurrence patterns of pests over several years and accumulating data, we conducted an analysis to evaluate the efficacy of preventive measures applied before the surge in mushroom fly infestation, typically observed in May. For preemptive control, physical measures involved installing air curtains at cultivation facility entrances and placing sticky traps and insect traps around entry points to block external entry and reduce internal insect density. Additionally, we applied an organic agricultural material, Dalmatian chrysanthemum extract, weekly alongside chemical control measures. To assess the reduction in mushroom fly populations, yellow sticky traps (15×25 cm) were placed at three locations within the mushroom cultivation facility, and the occurrence patterns before and after implementing preventive measures were compared. Compared to conventional practices, the application of preventive techniques resulted in a significant reduction, with a 60% decrease from 15 levels of mushroom flies/m² to 6 levels of mushroom flies/m² in May and a 40% decrease from 10 levels of mushroom flies/m² to 6 levels of mushroom flies/m² in June. While achieving over 50% efficacy during the peak mushroom fly season with preventive measures, we identified complementary actions such as blocking external sources (gaps in cultivation facility doors) and maintaining cleanliness around cultivation facilities (proper disposal of spent substrate) for further improvement. Comprehensive analysis and safety studies, including correlation analysis with contaminants and pathogens, are recommended to ensure the widespread adoption of mushroom fly preventive techniques for safe and stable mushroom production in the agricultural sector.

        Sentiment analysis is a method used to comprehend feelings, opinions, and attitudes in text, and it is essential for evaluating consumer feedback and social media posts. However, creating sentiment dictionaries, which are necessary for this analysis, is complex and time-consuming because people express their emotions differently depending on the context and domain. In this study, we propose a new method for simplifying this procedure. We utilize syntax analysis of the Korean language to identify and extract sentiment words based on the Reason-Sentiment Pattern, which distinguishes between words expressing feelings and words explaining why those feelings are expressed, making it applicable in various contexts and domains. We also define sentiment words as those with clear polarity, even when used independently and exclude words whose polarity varies with context and domain. This approach enables the extraction of explicit sentiment expressions, enhancing the accuracy of sentiment analysis at the attribute level. Our methodology, validated using Korean cosmetics review datasets from Korean online shopping malls, demonstrates how a sentiment dictionary focused solely on clear polarity words can provide valuable insights for product planners. Understanding the polarity and reasons behind specific attributes enables improvement of product weaknesses and emphasis on strengths. This approach not only reduces dependency on extensive sentiment dictionaries but also offers high accuracy and applicability across various domains.

        Approximately 40,000 elevators are installed every year in Korea, and they are used as a convenient means of transportation in daily life. However, the continuous increase in elevators has a social problem of increased safety accidents behind the functional aspect of convenience. There is an emerging need to induce preemptive and active elevator safety management by elevator management entities by strengthening the management of poorly managed elevators. Therefore, this study examines domestic research cases related to the evaluation items of the elevator safety quality rating system conducted in previous studies, and develops a statistical model that can examine the effect of elevator maintenance quality as a result of the safety management of the elevator management entity. We review two types: odds ratio analysis and logistic regression analysis models.

        Kimchi, a centuries-old Korean fermented food, has gained global popularity due to increased interest in Korean cuisine. However, little is known about the actual status of kimchi information provided by major foreign online encyclopedias. In this study, we analyzed the content and quality of kimchi information in major foreign online encyclopedias, such as Baidu Baike, Encyclopædia Britannica, Citizendium, and Wikipedia. Our results revealed that the kimchi information provided by these encyclopedias was often inaccurate or inadequate, despite kimchi being a fundamental part of Korean cuisine. The most common inaccuracies were related to the definition and origins of kimchi and its ingredients and preparation methods. Our findings highlight the need for more accurate and reliable information about kimchi in major foreign online encyclopedias. This is particularly important in the context of promoting Korean food culture and increasing international awareness of kimchi. To achieve this, the collaborative efforts of Korean food experts and online encyclopedias are needed to ensure the accurate representation of kimchi in these resources. In conclusion, our study shows that foreign online encyclopedias often contain incomplete, inaccurate information about kimchi. This shortcoming must be addressed to promote a more accurate and comprehensive understanding of kimchi and Korean cuisine.

        Park, Eunha. (2023). “Perceptions of “Hwanhyangnyeo,” “Wianbu,” “Yang-gongju” Through Example Sentences in Korean Dictionaries and the Internet Articles“. The Sociolinguistic Journal of Korea, 31(2), 29-58. This study investigated and analyzed examples of three terms found in dictionary entries and internet articles to examine the perceptions of war and women in Korean society. A preliminary examination of dictionary entries found that one dictionary’s referred to “hwanhyangnyeo” as a stigmatized term, used to expression hatred toward women even after returning home post the war. In the example sentences of “wianbu,” in the dictionaries, the phrase “other expressions” was commonly used, which precisely conveyed or demanded facts. Entries regarding “wianbu, Japan, and the government’s expressions” generally portrayed a negative view of “wianbu” victims and related issues. Further, concerning the example sentences of “yang-gongju,” in dictionaries, the most frequently used entry depicted it as an “expression of other people’s perception of yang-gongju.” Except for other expressions conveying factual information, two negative expression types related to “yang-gongju” were identified. When examining the usage of these expressions in internet articles, entries related to “the government’s response” were found to be the most prevalent. For “hwanhyangnyeo,” articles most frequently focused on “the history of ‘hwanhyangnyeo’.” Regarding articles containing “wianbu,” primary topic of interest was “the expedition of the Girl Statue in German.” Finally, articles concerning “yang-gongju” commonly referred to “the poor life of ‘yang-gongju.’”

        Recently, many studies are being conducted to extract emotion from text and verify its information power in the field of finance, along with the recent development of big data analysis technology. A number of prior studies use pre-defined sentiment dictionaries or machine learning methods to extract sentiment from the financial documents. However, both methods have the disadvantage of being labor-intensive and subjective because it requires a manual sentiment learning process. In this study, we developed a financial sentiment dictionary that automatically extracts sentiment from the body text of analyst reports by using modified Bayes rule and verified the performance of the model through a binary classification model which predicts actual stock price movements. As a result of the prediction, it was found that the proposed financial dictionary from this research has about 4% better predictive power for actual stock price movements than the representative Loughran and McDonald’s (2011) financial dictionary. The sentiment extraction method proposed in this study enables efficient and objective judgment because it automatically learns the sentiment of words using both the change in target price and the cumulative abnormal returns. In addition, the dictionary can be easily updated by re-calculating conditional probabilities. The results of this study are expected to be readily expandable and applicable not only to analyst reports, but also to financial field texts such as performance reports, IR reports, press articles, and social media.

        PURPOSES : This study focuses on advance traffic information to prevent secondary traffic accidents on express highways. The purpose of this study is to analysis the optimal scenario by evaluating the effect of each advance traffic information scenarios using virtual driving simulation. METHODS : By designing traffic information scenarios and services with a combination of VMS and mobile PUSH notifications, driver behavior in the event of a traffic accident was analyzed. For this, a simulation environment was designed through engineering analysis. Through virtual driving simulation, the driver's deceleration point and the perception-reaction time are analyzed. RESULTS : Four scenarios were designed and reviewed so that VMS and mobile PUSH notification can be provided simultaneously after the driver drove for 5 km. As a result of driving with 30 drivers, the drivers reacted fastest when VMS was installed, followed by mobile PUSH notification, VMS+mobile PUSH notification, and NOTHING. CONCLUSIONS : When designing traffic information service, it was observed that providing information through VMS alone is more efficient than providing two services of traffic information. Therefore, it can be used as basic data for preventing secondary accidents on express highway.

        Vietnam is a multi-ethnic country with many cultures, languages, and forms of texts that coexist independently and interactively. Among the Vietnamese ethnic minorities is the Tay, the most primarily populated one. Before the use of the Latinized script, the Tay people used to use Nom which is made up of the graphic, phonetic and semantic elements of Han characters. Currently, the cultural source of the Tay is one of the most precious cultural heritages of Vietnam. If we want to decode, research, explore and promote the values of this heritage, it is impossible not to have a good set of reference books, which are Nom-Tay (word-based and character-based) dictionaries. It is undeniable that the compilation of Tay-language dictionaries and texts has attracted interest, and been in implementation for about half a century, thanks especially to the government, research institutions, and generations of Vietnamese scholars. However, the achievements have not met the needs and utilization potential of the explored materials. With the extremely abundant resources of ancient Nom-Tay texts, with the proper attention and investment of the state and investment funds, and with researchers’ enthusiasm, the compilation of the Nom-Tay (word-based and character-based) dictionaries will, to be sure, attain remarkable achievements.
