The studies of correspondence between novel and nation-state, among which The Rise of the Novel by Ian Watt is supposed to be the first book, have flourished for more than twenty years, encouraged by Benedict Anderson's and Cathy Davidson's works. According to them, the novel should come simultaneously with, or after the foundation of the nation-state, and testify to its production or the emergence of its subject/citizen. This paper questions about these prepositions, trying to introduce a new paradigmatical approach, "between global and transnational historical approach," to first novels in transatlantic areas including England and atlantic coastal areas. In its complex relation to a variety of colonial, post-colonial, and transnational geopolitics, various cultural practices such as history, traveler's tales and epistolary novels can be included in the genre of the novel. The idea of the sexual contract by Carole Pateman is very useful because it helps more clearly understand the nature of relation between men and women in the capitalist reproduction, while the social contract tells about the relation between men as citizens. Unlike Freud in Totem and Taboo, Zilboorg argues that there were primordial and violent scenes such as rape before the first sexual contract. This paper will illuminate that "the rise of the novel" corresponded with the emergence of the sexual contract. In the so-called first novel Pamela, the heroine Pamela was threatened to be violated by Mr. B., and was really even confined in his cottage. Mary Rowlandson's The Captive Narrative shows that her body was confined as an English female captive, and troubled with imaginary rape by Indians which resulted in the unequal sexual contract between her and her puritan community in America. However, Leonora Sansay's Secret History in an alternative communality, which was not a nation-state, was different from both novels mentioned above, in that it shows the possibility of emancipation from their unequal marriage, the sexual contract. Therefore, it can be argued that "between global and transnational historical approach" has a possibility to provide a new vision of global sisterhood and solidarity to recognize globalized women's violence, and free themselves from the unequal sexual contract.

This paper analyzes the penalty tax system under the Customs Act of Korea and examines whether the penalty tax provision violate the constitutional principle of proportionality when imposed on a person who does not made import declaration intentionally or travelers who has not been made an import declaration of their carry-on items. It examines the provisions that adopt a penalty tax as a means to secure the effectiveness of the customs law. In relation to penalty tax, the case studies of the Supreme Court and Constitutional Court of Korea are analyzed by major issues such as the legal nature of the penalty tax, whether the penalty tax is unconstitutional, and the reasons for exemption from the penalty tax. There is no reasonable basis for the high penalty tax imposed on travelers' carry-on items for which import declaration has not been made. It is necessary to unify the penalty tax imposed when an import declaration is not made and the penalty tax on traveler's carry-on items. It is necessary to establish a limit on penalty tax and to create new regulations to exempt or reduce penalty tax when punished by administrative punishment to avoid double jeopardy. It is necessary to effectively secure the effectiveness of the Customs Act by converting the penalty tax into civil penalty that does not presuppose the faithful and accurate performance of tax obligations by the taxpayer. The government revised the penalty tax system in the Customs Act in 2019, but there are still many types of penalty tax and there are elements that are unconstitutional. It seems that the Korean government should lower the burden on the people by improving the system for the penalty tax system.

Purpose: This study seeks to explore the impact of COVID-19-induced boredom, a prevalent form of pandemic-related stress, on travel motivation and post-pandemic travel intentions. Additionally, it examines the interplay among travel motivation, travel constraints, and the willingness to pay more for travel experiences in the post-pandemic context. Methods: A PLS-SEM analysis was conducted to analyze the data. Data collection took place through an online survey in February and March 2021, with a total of 575 respondents participating. Participants provided responses regarding their current levels of boredom due to COVID-19, five different travel motivations, seven travel constraints, and their post-pandemic travel intentions. Additionally, participants were asked about their willingness to pay more for travel. Results: This study highlights the significant role of COVID-19-induced boredom in predicting post-pandemic travel intentions and the willingness to pay more for travel. Contrary to previous perceptions, boredom emerges as a driving factor, enhancing travel intentions during the pandemic. Additionally, relaxation becomes the primary motivation for travel during COVID-19, and structural constraints exert a noticeable impact on travel intentions, challenging previous assumptions. Stress levels directly influence the willingness to pay more during travel experiences, expanding the understanding of additional payment behavior in the context of travel. Conclusion: This study offers practical insights for tourism stakeholders. Recognizing and addressing boredom in marketing strategies, implementing aggressive additional payment options, and focusing on relaxation-oriented travel products are recommended to cater to post-pandemic traveler preferences and revive the tourism industry effectively.

Enterotoxigenk E. coli is one of the major causative agents of the infantile diarrhea and traveler's diarrhea. The heat-labile enterotoxin is thought to be a virulence factor in the pathogenesis of the diarrhea and to be a marker for identification of the enterotoxigenic E. coli from non pathogenic E. coli. Therefore knowledge about the heat-labile enterotoxin is essential not only for understanding the pathogenesis but also for the diagnosis of the diarrhea. However the in-vitro heat-labile enterotoxin production is reported to be greatly affected by the cultural condition. In this regards, this study was designed to know the optimal conditions for the production of the heat-labile enterotoxin by assaying the permeability factor in the 18 hours culture supernatant of E. coli 08K25(B2) H9 and of E. coli 015 H11. Results obtained were summerized as follows: 1. Amounts of heat-labile enterotoxin produced were greater at initial pH 8.5 than at 7.0 of CYES-2 broth culture. However, the bacterial growth itself was more abundant at 7.0 than at 8.5. 2. Heat-labile enterotoxin per unit volume of culture supernatant was greater at shaking culture than at standing culture condition, but ratio of the enterotoxin produced over the unit mass of E. coli calculated was greater at standing culture than shaking culture condition, indicating that the greater yields of the toxin produced at shaking culture was due to increase in E. coli cell mass compared to the standing culture condition: 3. The enterotoxin produced in the lincomycin(128 microgram/ml) supplemented media was 5 or 11 times greater on the basis of enterotoxin per unit mass of E. coli, compared to the lincomycin-non-supplemented media, indicating that lincomycin itself increases the enterotoxin production. 4. Treatment of 18 hours culture of E. coli with polymyxin B(0.2 mg/ml) for 1 hour increased the yields of enterotoxin amounting to 2 or 5 times of the non-treated control cultures.

Purpose Recently, there has been an increase in attempts to analyze social phenomena, consumption trends, and consumption behavior through a vast amount of customer data such as web search traffic information and social buzz information in various fields such as flu prediction and real estate price prediction. Internet portal service providers such as google and naver are disclosing web search traffic information of online users as services such as google trends and naver trends. Academic and industry are paying attention to research on information search behavior and utilization of online users based on the web search traffic information. Although there are many studies predicting social phenomena, consumption trends, political polls, etc. based on web search traffic information, it is hard to find the research to explain and predict tourism demand and establish tourism policy using it. In this study, we try to use web search traffic information to explain the tourism demand for major cities in Gangwon-do, the representative tourist area in Korea, and to develop a nowcasting model for the demand. Design/methodology/approach In the first step, the literature review on travel demand and web search traffic was conducted in parallel in two directions. In the second stage, we conducted a qualitative research to confirm the information retrieval behavior of the traveler. In the next step, we extracted the representative tourist cities of Gangwon-do and confirmed which keywords were used for the search. In the fourth step, we collected tourist demand data to be used as a dependent variable and collected web search traffic information of each keyword to be used as an independent variable. In the fifth step, we set up a time series benchmark model, and added the web search traffic information to this model to confirm whether the prediction model improved. In the last stage, we analyze the prediction models that are finally selected as optimal and confirm whether the influence of the keywords on the prediction of travel demand. Findings This study has developed a tourism demand forecasting model of Gangwon-do, a representative tourist destination in Korea, by expanding and applying web search traffic information to tourism demand forecasting. We compared the existing time series model with the benchmarking model and confirmed the superiority of the proposed model. In addition, this study also confirms that web search traffic information has a positive correlation with travel demand and precedes it by one or two months, thereby asserting its suitability as a prediction model. Furthermore, by deriving search keywords that have a significant effect on tourism demand forecast for each city, representative characteristics of each region can be selected.
