We This study aimed to quantitatively analyze the theme of 'libertinage' and the associated issues of reason and emotion in 『Dangerous Liaisons』, a novel considered a masterpiece of libertine literature and an epistolary novel of the 18th century, using digital analysis tools. First, based on the frequency analysis of word usage using Voyant and LIWC 22, we confirmed that libertinage is manifested with keywords such as 'love' and 'time'. With Voyant's 'Contexts' feature, it was found that the letters sent by Valmont to Madame de Tourvel and those sent by Madame de Merteuil both have 'love' as the central theme. However, emotional vocabulary was higher in the former, whereas strategic vocabulary was more prevalent in the latter. Additionally, it was observed that the most frequently used word in the letters sent by Madame de Merteuil is 'time', with a higher frequency than 'love'. Thirdly, using LIWC 22, we measured the analytical thinking and emotional tone of the letters exchanged by the main characters, and analyzed how these values changed according to the chapters. Through these analyses, we confirmed that this novel, alongside Rousseau's "New Eloise," anticipates romanticism by embracing the theme of 'emotion,' which was rejected by 18th-century Enlightenment ideals.

In systems such as railways, automobiles, and airplanes, system malfunctions may lead to accidents, which often cause serious personal injury and economic loss. In previous studies, failure analysis has been performed, and safety measures derived using the component level information to reduce damage when a failure occurs. However, in functional safety concept, a focus is placed on lowering the frequency of occurrence of failures by performing risks analysis, setting up safety goals, and designing safety functions. Therefore, it is necessary to study how to determine the required safety function that can reduce the failure frequency to the acceptable level. To achieve this, we first studied a failure modeling method using SysML. It was then presented how several alternatives can be assessed to determine the desired safety function by simulating the generated SysML failure models and calculating the ability to reduce the failure frequency. A case study of a railway signaling system was done, demonstrating the effectiveness of the approach. We assessed whether the safety objectives were met for the alternative design of the railway signaling system through M & S. The results can be useful in that it can be applied from the early design phase and allow to choose the appropriate safety function that satisfies safety objectives among various design alternatives.

호산구는 염증 반응에 의해 활성화되며, 주로 기생충 감염이나 알러지 질환 등에 대한 면역 작용을 담당한다고 알려져 있다. 호산구 증가증은 약물 반응, 알러지, 국소적인 기생충 감염 등에 의한 경우가 많지만, 자가면역성 질환이나 종양에 의한 경우도 있다. 최근 연구를 통해 위염의 대표적인 원인균 중 하나인 유문나선균 역시 위점막에서 나타나는 조직 호산구 증가증의 원인이 될 수 있다고 밝혀지고 있으나, 유문나선균에 의한 호산구 증가증 발생 기전이나 빈도는 아직까지 확립되지 않고 있다. 위점막 내 호산구 침윤과 동반되는 위염은 복통, 오심, 구토, 설사, 장폐색 등을 일으킬 뿐만 아니라, 아토피성 피부염, 천식, 위식도 역류, 염증성 장질환 등의 발생과 관련이 있다고 보고되고 있다. 위염 및 다양한 관련 질환에 의한 증상은 공중 근무자들의 임무 수행 능력을 저하시켜 항공기 사고를 발생시킬 수 있는 가능성을 가지고 있다는 점에서 항공의학적으로 매우 중요하며, 실제로 호산구성 위염이나 유문나선균 감염의 치료 여부가 공중 근무자에게 일시적 또는 영구적 비행임무정지를 부과할 수 있는 기준이 되기도 한다. 본 연구에서는 대한민국 공군 장병 환자를 대상으로 내시경을 통해 얻은 위점막 조직 내 호산구수를 측정하고, 이를 위점막 표면의 유문나선균 존재 유무와 관련지어 보았다. 111명 중 20명의 환자에서 한 고배율 시야 당 30개 이상의 호산구가 관찰되었고, 63명의 환자의 위점막 표면에서 유문나선균을 확인하였다. 또한 위점막 내 호산구의 밀도와 유문나선균의 존재 간의 관계는 통계학적으로 유의하였다. 본 연구의 결과는 대한민국 공군 장병을 대상으로 하여 조직 호산구 증가증과 유문나선균의 빈도 및 상호 관계를 최초로 분석했다는 점에서 의의가 있으며, 추후 유문나선균이 어떤 기전으로 위점막 조직 내 호산구의 증가에 관여하는지에 대한 연구를 진행하기 위한 기초 자료로서 활용될 수 있을 것이다.

Since the establishment of Security Business Act in 1976, the Korean private security industry has rapidly grown in the qualitative and quantitative aspects. In the circumstance, various roles of private security guards have been demanded. A private security guard as the first contactor of the users of multi-use facilities should first find an accident field situation and make a response when an accident occurs, and should give first aid as most as possible until emergency medical workers arrive. However, there is a lack of first-aid education for the private security guards who are responsible for the safety of facility users. Therefore, the purpose of this study is first to find how many times private security guards have job and first-aid education, and analyze how the education count influences their first-aid ability; secondly to analyze how private security guards' satisfaction with first-aid education influences their first-aid ability. To achieve the purpose, this researcher conducted a questionnaire survey on first-aid ability of the private security guards working in the metropolitan areas. For data analysis, Stata se/ 14.0ver was applied. For the analysis on validity and reliability, exploratory factor analysis was conducted and a Cronbach's a value was drawn. To find the actual conditions of first-aid education, frequency analysis, inter-group difference analysis, and multi-regression analysis were conducted. According to the data analysis, there were not enough times of job education and first-aid education for private security guards, and their satisfaction with first-aid education and first-aid ability were difference depending on the job and first-aid education counts. Also, their satisfaction with first-aid education partially influenced their first-aid ability.

There have been growing concerns among people about food safety due to insufficient information on foodborne pathogens. In this study, we developed a risk priority of 15 foodborne pathogens. For the priority determination we collected risk profile criteria information from CODEX Alimentarius Commission and developed countries. The basis for criteria we selected from information of surveillance were frequency and severity of disease, frequency of consumption and probability of cross-contamination. We also considered foodborne pathogens which have been managed in developed countries though those pathogens are not currently managed appropriately in Korea. Priorities were divided into three groups following these consideration. The first priority group includes Norovirus, pathogenic E. coli, Salmonella spp, Clostridium botulinum and Listeria monocytogenes. The second priority group includes Vibrio parahaemolyticus, Stapylococcus aureus, Campylobacter jejuni and Bacillus cereus, and the third priority group includes Clostridium perfringens, Yersinia enterocolitica, Shigella spp, Cronobacter sakazakii and Hepatitis A virus. Our results could be applied to prevent foodborne illness from fresh produce.

In dense cities, which are covered by many impermeable areas, rainwater flows quickly along the roads and collects in certain areas. The surface runoff that fails to get intercepted by the roadside rain gutters results in a wider flow of water along the sides, which in turn increases the amount of water on the road and causes traffic congestion as well as accidents due to slippage. Based on these issues, this study was carried out in order to propose an intercepted flow calculation formula. To this end, the maximum longitudinal slopes of arterial roads and expressways were reflected to depict a road condition of 2~10 %, while a general traverse slope of 2 % was selected for the traverse slope on the side. As for the road lane condition, two, three, and four lanes were chosen for the area from the centerline to the sidewalk. As for the experimental flow rate, the rainwater runoffs at the actual design frequency of 5, 10, 20, and 30 years for road conditions were converted into experimental flow rates, and as a result, flow rates ranging from 1.36 l/s to 3.96 l/s were divided into ten flow rates for a hydraulic experiment. Also, an equation taking into consideration the inflow velocity and flow width along the roadsides was proposed. The results of the experiment showed an increase in flow width and a decrease in interception rate. Also, the inflow velocity at a traverse slope of 2 % was measured, while increasing the longitudinal slope. Accordingly, an equation for calculating the flow intercepted by rain gutters at a flow width reflecting the longitudinal slope of the road and rainwater runoff, according to the design frequency, was derived by performing a regression analysis using IBM SPSS Statistics 24. It is deemed that the equation derived in this study will be useful in designing rain gutters for roads.

The purpose of this study was to investigate the effects of offering similar experiences for hypothesis-generation based on abduction. Two hundred and seventy eight students in Seoul(8th and 10th grades) were requested to propose causal questions and generate hypotheses after observing an unfamiliar situation. Then, after having been presented numerous similar experimental situations to initial situation, the students were asked to regenerate a hypothesis. When the $X^2$ analysis was done to determine differences in hypothesis generation before and after offering the similar experimental situations, a meaningful difference appeared(p<.001). This study proposes that offering similar experimental situations ease hypothesis-generation based on abductive reasoning. Additionally, the second meaningful difference was discovered when the $X^2$ analysis was carried out to find differences in causal question proposal and hypothesis generation among students who had varied cognitive levels(p<.05) Considering the findings of the study, a progressive stage offering similar scenarios may further abductive reasoning while implementing lessons related to hypothesis generation in middle and high school.
