  • Researchers have endeavored to identify the etiology of inflammatory bowel diseases, including Crohn's disease and ulcerative colitis. Though the pathogenesis of inflammatory bowel diseases remains unknown, dysregulation of the immune system in the host gastrointestinal tract is believed to be the major causative factor. Omics is a powerful methodological tool that can reveal biochemical information stored in clinical samples. Lipidomics is a subset of omics that explores the lipid classes associated with inflammation. One objective of the present systematic review was to facilitate the identification of biochemical targets for use in future lipidomic studies on inflammatory bowel diseases. The use of high-resolution mass spectrometry to observe alterations in global lipidomics might help elucidate the immunoregulatory mechanisms involved in inflammatory bowel diseases and discover novel biomarkers for them. Assessment of the characteristics of previous clinical trials on inflammatory bowel diseases could help researchers design and establish patient selection and analytical method criteria for future studies on these conditions. In this study, we curated literature exclusively from four databases and extracted lipidomics-related data from literature, considering criteria. This paper suggests that the lipidomics approach toward research in inflammatory bowel diseases can clarify their pathogenesis and identify clinically valuable biomarkers to predict and monitor their progression.

  • This article aims to explain the 'people-image' of Bakhtin's works in the light of "Transgredience" and "Transition." According to Bakhtin, the real core of every culture is the people. But he did try to answer the question "what is the people?" I think, the secret of Bakhtinian thought is located in the people-image, because it is the one of the territories that have not been explained. For this purpose, we have to examine four images represented by Bakhtin, - rogue, clown, fool, thief. These images are the concrete and individualized images of people, who can characterize the power of transgredience and transition. They commonly act for changing ordinary borders of identities formulated with nationality, property, status, classes, sex and so forth. In this sense, Bakhtin thinks that the masks are the real nature which can show the mutational power of Being. That is the kernel of Bakhtin's people-image that makes and changes every cultural world. When we accept and practise this perspective positively, we will realize that Bakhtin's position is close to the cultural politics, because a practical power of thought cannot help but being political. That's why we have to investigate Bakhtin's people-image from a vantage point of "Transgredience" and "Transition."

  • This study was carried out to gather basic data for the purpose of proposing a plan to improve the water quality and conserve the aquatic ecosystem of the Singu Agricultural Reservoir in Korea. The water quality, sediment composition, benthic macroinvertebrate distribution, and fish distribution in the Singu Reservoir were analyzed; the reservoir is located close to farmlands, forests, villages, and livestock breeding areas. The results of the water quality analysis are as follows: 5.8~7.8 mg/L for dissolved oxygen, 13.1~20.7 mg/L for chemical oxygen demand, 14.4~18.8 mg/L for suspended solid, 0.96~1.70 mg/L for total nitrogen, 0.07~0.11 mg/L for total phosphorous, and $41.9{\sim}49.8{\mu}g/L$ for $chlorophyll-{\alpha}$. In total, 75 benthic macroinvertebrate specimens belonging to 4 classes, 7 orders, 14 families, and 17 species were recorded. The ecological scores of the benthic macroinvertebrate communities ranged from 11 to 23. Fish specimens recorded belonged to two families and four species. The dominant fish species were Carassius auratus and Pseudorasbora parva, both of which are water-pollutant tolerant species.

  • Purpose: This study aimed to explore the environmental factors affecting childhood obesity using photovoice from the perspectives of students, parents, and teachers in the community. Methods: Six school students, seven parents, and seven school teachers completed an assignment requiring them to take 24 pictures and participate in group discussions. After training session, the participants were asked to take pictures associated with food and physical activity environments related to childhood obesity at home, school, and within their communities for two weeks and to submit the pictures with records. Each group had four sessions for discussion. Results: School cafeteria, convenience stores near schools, instant food and fast food joints, food delivery, and high-calorie snacks comprised the food environmental factors. Lack of physical activity classes at school, commuting by car, barriers to physical activity, and use of smart-phone were environmental factors that inhibited physical activity. Conclusion: To reduce childhood obesity, the creation of a supportive environment for encouraging the consumption of healthy foods and enhancing physical activity should be considered. Modifications of and improvement to the obesogenic environment might be a good strategy to prevent and reduce childhood obesity.

  • The purpose of this study is to understand the daily lives of adolescents during the COVID-19 pandemic and to provide educational implications for enhancing the competencies of adolescents living in rapidly-changing environments. To this end, the photovoice method, consisting of orientation, documentation, discussion, and analysis, was employed to study nine adolescent participants, who were interested in sharing aspects of their daily lives. The results yielded four themes and nine sub-themes. The first theme is "home life", which is composed of two sub-themes: most comfortable to be alone and EA (eating alone) for lunch. The second theme is "leisure life", which consists of two sub-themes: the virtual world of playing with friends and exercise is the only way out to breathe. The third theme is "school life", which consists of three sub-themes: time for inner exploration and reflection, cracks in daily life due to excessive autonomy, and pros and cons of virtual classes. The fourth theme is "the voice of adolescents", which consists of two sub-themes: requiring adults to set a golden example and anxious voices due to an uncertain future. This photovoice method of study is meaningful in that it explores the daily lives of adolescents during the COVID-19 pandemic and provides valuable educational implications.

  • The purpose of this study was to present a class case that verified the validity, reliability, and usefulness of a portfolio assessment in a cohousing class in the housing area of home economics. To achieve this objective, 241 male and female students in eight classes of the third grade of a junior high school in Gyeonggi-do, Korea, were enrolled in a project class on establishing a cohousing village in which the portfolio assessment method was applied for a total of 10 sessions for approximately four weeks from May 24 to June 16, 2021. To ensure the validity of the portfolio assessment, we designed the lesson after presenting the curriculum goals in detail using the backward design model and developed a specific rubric and conducted all evaluations and feedback based on the rubric to ensure objectivity and reliability. The online tool Padlet was used as a portfolio, which allowed students to easily upload their work, receive feedback from the teacher, and interact with their peers. After the class, the students reflected on the rubric and were generally satisfied with the class using portfolio assessment. This study is expected to facilitate the use of the portfolio assessment method in the classroom, while also supporting student growth and development.
