Yumin Park(Yumin Park),Yong-Wook Shin(Yong-Wook Shin) 인간식물환경학회 2022 인간식물환경학회지 Vol.25 No.5

Background and objective: Since the COVID-19 pandemic, people have been staying at home more and “balcony vegetable gardens,” a form of urban agriculture, have been mentioned more frequently. As a result of the Korea Housing Survey in 2020, the percentage of households living in apartments among general households in Korea was 51.1%, but there is insufficient research to understand public perception and trends of the balcony vegetable gardens. Therefore, this study was conducted to analyze the trends of balcony vegetable gardens over the last 4 years including before and after the COVID-19 outbreak and to provide basic data for effective application to related policies and research. Methods: A total of 5,011 posts that mentioned balcony vegetable gardens were collected from Naver blogs and cafes from January 1, 2018 to December 31, 2021. To tokenize nouns, Okt morphological analysis of KoNLPy was used, and keywords were derived using TfidfVectorizer of Scikit-learn library. Following that, LDA topic modeling was performed by setting the hyper parameters as α= 0.1, β = 0.01 and iterations = 1,000. The above analysis was conducted using Python 3.9.5. Results: Before the outbreak of COVID-19, balcony vegetable gardening began to receive attention and vitalized as a form of participation in urban agriculture, but after the outbreak, they are established as an activity for healing, emotional support, environmental campaign, and healthy hobby. Especially during the COVID-19 pandemic, people clearly seemed to seek a more sustainable lifestyle through balcony vegetable garden activities. This shows the values and expected outcomes the public has toward urban agriculture. Conclusion: Balcony gardening activities heal the public, and this healing effect could be a key to the revitalization and development of urban agriculture. These findings can help establish policies and set the directions for urban agriculture that reflect the values and expected outcomes the public has toward urban agricultural activities.

Yumin Park,Yong-Wook Shin 인간식물환경학회 2021 인간식물환경학회지 Vol.24 No.5

Background and objective: The prolonged COVID-19 pandemic has had significant impacts on mental health, which has emerged as a major public health issue around the world. This study aimed to analyze trends and network structure of ‘grow-your-own (GYO)’ through Instagram, one of the most influential social media platforms, to encourage and sustain home gardening activities for promotion of emotional support and physical health. Methods: A total of 6,388 posts including keyword hashtags ‘#gyo’ and ‘#growyourown’ on Instagram from June 13, 2020 to April 13, 2021 were collected. Word embedding was performed using Word2Vec library, and 7 clusters were identified with K-means clustering: GYO, garden and gardening, allotment, kitchen garden, sustainability, urban gardening, etc. Moreover, we conducted social network analysis to determine the centrality of related words and visualized the results using Gephi 0.9.2. Results: The analysis showed that various combinations of words, such as #growourrownfood, #growourrownveggies, and #growwhatyoueat revealed preference and interest of users in GYO, and appeared to encourage their activities on Instagram. In particular, #gardeningtips, #greenfingers, #goodlife, #gardeninglife, #gardensofinstagram were found to express positive emotions and pride as a gardener by sharing their daily gardening lives. Users were participating in urban gardening through #allotment, #raisedbeds, #kitchengarden and we could identify trends toward self-sufficiency and sustainable living. Conclusion: Based on these findings, it is expected that the trend data of GYO, which is a form of urban gardening, can be used as the basic data to establish urban gardening plans considering each characteristic, such as the emotions and identity of participants as well as their dispositions.

The Effect of Social Media Content Types on User Reactions: Focused on a Case Study of Kew Gardens

Yumin Park,Yong-Wook Shin 인간식물환경학회 2021 인간식물환경학회지 Vol.24 No.2

Background and objective: Instagram, an image-based social media, is being used as an important outlet for the communication and place marketing of public spaces. The purpose of this paper was to analyze how types of place-based content affect user reactions (Likes and Comments) on Instagram in order to provide basic data on the operation and utilization of social media by public places such as botanical gardens and arboretums. Methods: A total of 850 posts uploaded to the Instagram account of Kew Gardens from November 6, 2014 to July 3, 2020 were classified using 14 subject codes. Multiple regression analysis was performed to evaluate the user’s reaction between the dependent variables (“Likes”, “Comments”) and the independent variables (14 subject codes). Results: The findings showed that user reactions appear to differ depending on the typology of the content, and “Likes” and “Comments” were presented in independent behavioral reactions. In particular, “close-ups of plants (botanic, macro),” “plant colony (botanic, wide),” “place-specific landscape (building, landscape),” “anniversary” and “information” showed positive impacts on both “Likes” and “Comments”which could lead to electronic word-of-mouth and content sharing. Conclusion: Based on these findings, it can be argued that the typology of a botanical garden’s content can be used to determine factors that affect the immediate reactions and enhance engagement with users.

Trend Analysis of Pet Plants Before and After COVID-19 Outbreak Using Topic Modeling: Focusing on Big Data of News Articles from 2018 to 2021

Yumin Park,Yong-Wook Shin 인간식물환경학회 2021 인간식물환경학회지 Vol.24 No.6

Background and objective: The ongoing COVID-19 pandemic restricted daily life, forcing people to spend time indoors. With the growing interest in mental health issues and residential environments, ‘pet plants’ have been receiving attention during the unprecedented social distancing measures. This study aims to analyze the change in trends of pet plants before and during the COVID-19 pandemic and provide basic data for studies related to pet plants and directions of future development. Methods: A total of 2,016 news articles using the keyword ‘pet plants’ were collected on Naver News from January 1, 2018 to August 15, 2019 (609 articles) and January 1, 2020 to August 15, 2021 (1,407 articles). The texts were tokenized into words using KoNLPy package, ultimately coming up with 63,597 words. The analyses included frequency of keywords and topic modeling based on Latent Dirichlet Allocation (LDA) to identify the inherent meanings of related words and each topic. Results: Topic modeling generated three topics in each period (before and during the COVID-19), and the results showed that pet plants in daily life have become the object of ‘emotional support’ and ‘healing’ during social distancing. In particular, pet plants, which had been distributed as a solution to prevent solitary deaths and depression among seniors living alone, are now expanded to help resolve the social isolation of the general public suffering from COVID-19. The new term ‘plant butler’ became a new trend, and there was a change in the trend in which people shared their hobbies and information about pet plants and communicated with others in online. Conclusion: Based on these findings, the trend data of pet plants before and after the outbreak of COVID-19 can provide the basis for activating research on pet plants and setting the direction for development of related industries considering the continuous popularity and trend of indoor gardening and green hobby.

PEGylated TRAIL ameliorates experimental inflammatory arthritis by regulation of Th17 cells and regulatory T cells

Park, Jong-Sung,Oh, Yumin,Park, Ogyi,Foss, Catherine A.,Lim, Sung Mook,Jo, Dong-Gyu,Na, Dong Hee,Pomper, Martin G.,Lee, Kang Choon,Lee, Seulki Elsevier 2017 Journal of controlled release Vol.267 No.-

<P><B>Abstract</B></P> <P>TNF-related apoptosis-inducing ligand (TRAIL) is a death ligand that can induce apoptosis in cells expressing its cognate death receptors (DRs). Previously, we demonstrated the therapeutic potential of recombinant human TRAIL in experimental rheumatoid arthritis (RA) models. However, the mechanisms of how DR-mediated apoptosis elicits these actions is not known. Here, we show that systemically administering a potent, long-acting PEGylated TRAIL (TRAIL<SUB>PEG</SUB>) is profoundly anti-rheumatic against two complementary experimental RA mouse models, collagen-induced arthritis (CIA) and collagen antibody-induced arthritis (CAIA), <I>via</I> targeting IL-17 secreting Th17 cells and regulatory T cells (Treg). Systemic administration of TRAIL<SUB>PEG</SUB> after disease onset ameliorated the severity of inflammatory arthritis including arthritis indices, paw thickness, cartilage damage and neutrophil infiltration in both CIA and CAIA models. Additionally, the levels of inflammatory molecules (p-p65, ICAM-1, Cox-2, MMP3, and iNOS), pro-inflammatory cytokines (TNF-α, IL-1β, IFN-γ, IL-6, IL-17) and accumulation of activated macrophages were significantly reduced after the TRAIL<SUB>PEG</SUB> treatment. Importantly, TRAIL<SUB>PEG</SUB> decreased the number of pro-inflammatory Th17 cells in inflamed arthritic joints through TRAIL-induced apoptosis while increasing anti-inflammatory Treg population <I>in vivo</I>. These results suggest that TRAIL<SUB>PEG</SUB> ameliorates autoimmunity by targeting the Th 17-Tregs axis, making it a promising candidate drug for the treatment of RA.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Minkyung Park,Young-Lai Cho,Yumin Choi,Jeong-Ki Min,Young-Jun Park,Sung-Jin Yoon,Dae-Soo Kim,Mi-Young Son,Su Wol Chung,Heedoo Lee,Seon-Jin Lee 생화학분자생물학회 2023 BMB Reports Vol.56 No.2

Particulate matter is an air pollutant composed of various components,and has adverse effects on the human body. Particulatematter is known to induce cell death by generating animbalance in the antioxidant system; however, the underlyingmechanism has not been elucidated. In the present study, wedemonstrated the cytotoxic effects of the size and compositionof particulate matter on small intestine cells. We found thatparticulate matter 2.5 (PM2.5) with extraction ion (EI) components(PM2.5 EI), is more cytotoxic than PM containing only polycyclicaromatic hydrocarbons (PAHs). Additionally, PM-inducedcell death is characteristic of ferroptosis, and includes ironaccumulation, lipid peroxidation, and reactive oxygen species(ROS) generation. Furthermore, ferroptosis inhibitor as liproxstatin-1and iron-chelator as deferiprone attenuated cell mortality, lipidperoxidation, iron accumulation, and ROS production after PM2.5EI treatment in human small intestinal cells. These results suggestthat PM2.5 EI may increase ferroptotic-cell death by ironaccumulation and ROS generation, and offer a potential therapeuticclue for inflammatory bowel diseases in human smallintestinal cells.

A Demand Survey on the Priority of Agricultural College Students’ Core Competencies Required by Agriculturel Companies: A case study on G University

박유민(Yumin Park),신용욱(Yong-Wook Shin) 인간식물환경학회 2021 인간식물환경학회지 Vol.24 No.4

Background and objective: As the agricultural industry becomes a more convergent industry, it is believed that the demand for human resources by companies will change. Therefore, a survey was conducted to investigate the human resources required by agriculture companies. Methods: In the survey on 77 agriculture companies, 98.7% of respondents answered that new employees with a college degree needed additional training to adapt to practical affairs. Results: The first priority of education was “community spirit” (22.1%) and the second priority was “convergence capability” (15.6%). The most important educational goal desired by agricultural companies was “cultivating human resources with community spirit and ethical judgment”, followed by “cultivating human resources with serious communication and problem-solving skills”, and “cultivating human resources with scientific thinking and unique creative imagination.” Sub-competencies that companies want agricultural colleges to strengthen were “community spirit” 4.32(SD=0.96), “desirable values” 4.30 (SD = 1.05), “sympathy” 4.28 (SD = 0.95), “convergence capability” 4.16 (SD = 0.88), “creativity” 4.11 (SD = 0.83), “civic spirit” 4.10 (SD = 0.91), and “rational/critical thinking” 3.94 (SD = 1.04). There was a significant difference in sub-competencies that require reinforcement depending on the number of full-time employees. “Creativity” was most necessary in companies with less than 3 employees (4.39), and 4~7 employees (4.33), and “aesthetics”” in companies with less than 3 employees (3.94), and 4-7 employees (3.61) “Civic spirit” was most necessary in companies with 31 employees or more (4.33). Conclusion: The most important educational goal desired by companies was “cultivating human resources with community spirit and ethical judgment”.

Effect of local anesthetic volume (20 vs. 40 ml) on the analgesic efficacy of costoclavicular block in arthroscopic shoulder surgery: a randomized controlled trial

Jo Yumin,Oh Chahyun,Lee Woo-Yong,Chung Hyung-Jin,Park Hanmi,Park Juyeon,Lee Jieun,김윤희,고영권,Chung Woosuk,Hong Boohwi 대한마취통증의학회 2024 Korean Journal of Anesthesiology Vol.77 No.1

Background: Among the various diaphragm-sparing alternatives to interscalene block, costoclavicular block (CCB) demonstrated a low hemidiaphragmatic paresis (HDP) occurrence but an inconsistent analgesic effect in arthroscopic shoulder surgery. We hypothesized that a larger volume of local anesthetic for CCB could provide sufficient analgesia by achieving sufficient supraclavicular spreading.Methods: Sixty patients scheduled for arthroscopic rotator cuff repair were randomly assigned to receive CCB using one of two volumes of local anesthetic (CCB20, 0.75% ropivacaine 20 ml; CCB40, 0.375% ropivacaine 40 ml). The primary outcome was the rate of complete analgesia (0 on the numeric rating scale of pain) at 1 h postoperatively. The secondary outcomes included a sonographic assessment of local anesthetic spread, diaphragmatic function, pulmonary function, postoperative opioid use, and other pain-related experiences within 24 h postoperatively. Results: The rates of complete analgesia were not significantly different (23.3% [7/30] and 33.3% [10/30] in the CCB20 and CCB40 groups, respectively; risk difference 10%, 95% CI [–13, 32], P = 0.567). There were no significant differences in other pain-related outcomes. Among the clinical factors considered, the only factor significantly associated with postoperative pain was the sonographic observation of supraclavicular spreading. There were no significant differences in the incidence of HDP and the change in pulmonary function between the two groups.Conclusions: Using 40 ml of local anesthetic does not guarantee supraclavicular spread during CCB. Moreover, it does not result in a higher rate of complete analgesia compared to using 20 ml of local anesthetic in arthroscopic shoulder surgery.

The impacts of three-dimensional anatomical atlas on learning anatomy

Sohyun Park,Yumin Kim,Sohyeon Park,신정아 대한해부학회 2019 Anatomy & Cell Biology Vol.52 No.1

Gross anatomy has traditionally been the foundation of medical education. Medical students have learned the structure of the human body through dissection, lecture, and textbooks. As tablets and three-dimensional (3D) applications are developed, 3D atlas applications are utilized in learning anatomy by medical students. The purpose of this research is to investigate the impacts of 3D atlas applications on students’ understanding of gross anatomy. This research was targeted at medical students taking the Anatomy and Embryology class in 2017 and 2018, at Ewha Womans University. The correlation between use of 3D atlas and student's results on the Anatomy and Embryology test was analyzed. An open-book anatomy quiz was also carried out to analyze the correlation between the type of atlas each student refers to and the results of the quiz. Independent t test between groups did not show statistically significant difference in the results of the Anatomy and Embryology test. However, the group referring to 3D atlas showed significantly higher results on the simple questions of the open-book anatomy quiz (P<0.05). In conclusion, 3D atlas is not very helpful in acquiring deep anatomical knowledge or memorizing the location of anatomical structures, but it can simply aid in the rapid identification of anatomical structures. Additionally, the 3D atlas will show good synergy with the two-dimensional atlas if used properly in anatomy education, because most students think it is useful to use the 3D atlas.
