Listeria monocytogenes is a highly pathogenic gram-positive bacterium that is easily isolated from cheese, meat, processed meat products, and smoked salmon. A zero-tolerance (n=5, c=0, m=0/25 g) criteria has been applied for L. monocytogenes in cheese meaning that L. monocytogenes must not be detected in any 25 g of samples. However, there was a lack of scientific information behind this criteria. Therefore, in this study, we conducted a risk assessment based on literature reviews to provide scientific information supporting the baseline and to raise public awareness of L. monocytogenes foodborne illness. Quantitative risk assessment of L. monocytogenes for cheese was conducted using the following steps: exposure assessment, hazard characterization, and risk characterization. As a result, the initial contamination level of L. monocytogenes was -4.0 Log CFU/g in cheese. The consumption frequency of cheese was 11.8%, and the appropriate probability distribution for amount of cheese consumed was a Lognormal distribution with an average of 32.5 g. In conclusion, the mean of probabilities of foodborne illness caused by the consumption of cheese was 5.09×10-7 in the healthy population and 4.32×10-6 in the susceptible population. Consumption frequency has the biggest effect on the probability of foodborne illness, but storage and transportation times have also been found to affect the probability of foodborne illness; thus, management of the distribution environment should be considered important. Through this risk assessment, scientific data to support the criteria for L. monocytogenes in cheese could be obtained. In addition, we recommend that further risk assessment studies of L. monocytogenes in various foods be conducted in the future.

To investigate the influence of hand cream of domestic and foreign brands on the purchase tendency, a survey was conducted on hand cream application, purchase tendency, and perception of 105 women in a metropolitan area. Market research was then conducted to compare the hand cream cost, quantity, and total substance, and the hand creams were sorted according to high-price and low-price, and foreign brand and domestic brand, and a clinical demonstration was conducted by back-hand application on 17 recipients to analyze the moisture and skin oil differences and the moisture endurance. As a result, the percentage of subjects who perceived that the price and brand of hand cream affects the quality was higher than those who did not, and the hand cream prize per 1mg (g) varied as much as fourfold among the high-price and low-price, and among foreign and domestic brands. The result of the total substance comparison, glycerin the moisturizer and cetearyl alcohol the skin conditioner were included in all hand creams. As a result of the clinical demonstration, the difference in moisture and skin oil difference and moisture endurance between the high-price and low-price and foreign brand did not show a statistically significant difference. These results show that there are no relationships between skin moisture and sebeum of the brand. Therefore, considering that hand cream is a highly consumptive product that is used multiple times on a daily basis, these results might provide fundamental data that could contribute to the increase in hand cream product quality by determining the consumers' needs.

Service-Learning (S-L) is an experiential learning-based teaching-learning method that connects students with curriculum and school-based community service and raises students' academic ability and social responsibility awareness through the value of 'reflection' and 'reciprocity'. This study analyzed the case of S-L course of 'History of Science and Inquire Activity' for pre-service science teachers (PSTs). The S-L lectures linked to the subjects of the History of Science were conducted in terms of three stages (Preparation-Implementation-Evaluation), and S-L classes were conducted in three schools five times. The educational effects of S-L lectures were analyzed by collecting questionnaires, class observation and self-reported reflection diary. The PSTs were able to understand the school realities and improve the teaching abilities and pedagogic content knowledge through educational service activities. The PSTs who participated in the S-L course had hard time due to excessive learning time, the difficulty of preparing the class, the fear of the class, and trial and error. Nonetheless, most of the students responded that they were very satisfied (4.68) with the S-L lecture, and that they could develop self-efficacy for their future teaching career thank to this learning experience.

This study aims to provide a theoretical examination of symmetry and its implications for science education. For this purpose, first, we examined the way of thinking of Western science in general through ancient Greek scholars. Second, we divided the perception of symmetry into ancient and modern times. Third, we draw out the implications for science education. The results of this study show that, first, the way of thinking in Western science is 'abstraction', which began with Parmenides and was established by Plato. Second, the ancient perception of symmetry is symmetry as beautiful proportions and harmony based on abstraction, and the modern perception of symmetry is symmetry as an invariant perspective based on abstraction that seeks to find constancy in change. We examined Eratosthenes' experiment to measure the circumference of the earth as an example of ancient symmetry, and Galilean relativity or transformation as examples of modern symmetry. Third, the implications for science education are as follows. Awareness of symmetry can help educate students about the nature of science, as it is a central theme that runs through ancient and modern science. Second, the Eratosthenes' experiment and Galilean relativity or transformations are not represented in the 2022 revised curriculum, but could support understanding of science and key competencies and concepts. Finally, an integrated approach to science education centered on symmetry can have a positive impact on scientific attitudes and interest.

This research analyzed articles about the disability under the 「The Disabled Person Welfare Law」 in a major daily newspaper. A total of 7,684 articles on disability were collected from homepages of the three newspapers , , and . Through network text analysis and content analysis, we considered about "The perspective of Disability" based on "Multiple Disability Model". As a result of this research, when comparing individual models versus social models, individual models have a higher rate 64.31% than social models 35.69%. According to the newspapers, the major perception of Disability is a traditional individual model, which means disability must be solved by individuals. In addition, due to low social and institutional supports, the public's attention and consideration required for the disabled, socially weak people. This research implied that despite the changing times of looking at disability, three newspapers are still staying in the traditional paradigm. Therefore, It is required that viewing a disability from the perspective on disabled people, and a mature awareness that recognizes the diversity of individual needs. The significance of this study can be found in the fact that no attempt has been made to treat the disability perspectivec in newspaper articles as quantitative and qualitative data.

Prior hardware-centered rural development projects implemented top-down rural community regeneration via the local government in accordance with central government agency policies. To improve this, software-centered projects have been promoted since 2000. With central agency-led rural development projects changing into local government-led ones, rural community regeneration has been built per village. Although rural community regeneration projects appear to have implemented a bottom-up development currently, the top-down development procedures being facilitated by the intervention of administrative institutions have not disappeared. In this regard, the purpose of this research thesis is to effectively perform bottom-up development methods that go one step further from the current process of rural community regeneration. As the research site, this thesis selected Geochang, which has difficulties in being steadily maintained and operated despite the development of various rural community regeneration projects. Subsequently, it determined the current status and substantial analysis of a project of the rural community regeneration in Geochang through 1:1 interviews with civil servants in charge of administration as well as conducted a prior study on rural resident awareness of rural community regeneration through a survey of village head members and in-depth interviews with rural residents. Based on these data, a 10 times-round table conference was held under the participation of pertinent civil servants, professionals and rural residents to select practical strategies for cooperative rural community regeneration in Geochang as five key areas: local food, culture & welfare, rural villages, community development, and urban and rural interchanges. In addition, it is considered that the project of building villages must be implemented by establishing steadfast administrative co-operation systems, strengthening rural residents' participation capacities and supporting professionals' systemic integrated operation and maintenance. By doing so, this research thesis sought to determine practical strategies in the cooperative rural community regeneration in Geochang. It is expected that bottom-up development rural community regeneration will be built and introduced in each rural community in the future.

This research experiments on the workers' recognition of the fire alarm sound for sirens and portable loudspeakers in a small construction site. As a result of analyzing the siren alarm sound recognition from measuring on the 1st, 2nd, and 4th floors, the sound was more unrecognizable on the 4th floor than on the 1st, and 1 person on the 1st floor was unable to recognize all sounds. In the case of the 2nd floor, one person could not notice the alarm in the last 3rd trial, and another did not realize it all three times. For the 4th floor, 3 people demonstrated unrecognition in all 3 tests. As a result of analyzing the recognition of portable loudspeaker alarm sounds, 1 person could not recognize all sounds on the first floor. In the case of the 2nd floor, 2 people were confirmed to be unable to notice, and lastly, 4 people could not recognize all trials on the 4th floor. The subjects who didn't recognize the sound were unable to distinguish between portable loudspeaker alarm sound and work noise due to the workspace and obstacles.
