In this paper, we present a new kind of duality between intersection bodies and projection bodies. Furthermore, we establish some counterparts of dual Brunn-Minkowski inequalities for intersection bodies.

The mixed chord-integrals are defined. The Fenchel-Aleksandrov inequality and a general isoperimetric inequality for the mixed chordintegrals are established. Furthermore, the dual general Bieberbach inequality is presented. As an application of the dual form, a Brunn-Minkowski type inequality for mixed intersection bodies is given.

This paper discusses American disability theater's representations of disability identity and disability identity politics. Dramatists John Belluso and Lynn Manning, among others, present characters with disabilities who experience oppressions at multiple, interlocking levels of domination on the basis of disability, race, and ethnicity. In Manning's Shoot, the black, blind hero iterates episodes in which he experienced discrimination and insults in encounters with whites who used derogatory racist words or belittled him and with some school children who taunted him for just being blind. This play, as in Manning's solo performance, Weights, presents narratives of a blind person traversing multiple locations of oppression in "a long litany of losses" in a white-dominated and ableist society. Belluso's Gretty Good Time similarly weaves together stories of disabled women, Gretty and Hideko, who bond together to resist the dominant ideology that reduces them into titillating commodities of mass consumption. Hideko's story serves the two-fold function of both affirming the specificity of her individual experience as an ethnic other and espousing the communal experience of stigmatization she shares with other disabled women like Gretty. In these plays, the intersection of the identity categories of disability, race, and ethnicity highlights the diversity of the body and the fluidity of boundaries, foregounding the specificity of disabled bodies, while at the same time overthrowing the hierarchical binarism between disabled and "normal" bodies.

Floods are becoming more severe and frequent due to global warming-induced climate change. Water disasters are rising in Korea due to severe rainfall and wet seasons. This makes preventive climate change measures and efficient water catastrophe responses crucial, and synthetic aperture radar satellite imagery can help. This research created 1,423 water body learning datasets for individual water body regions along the Han and Nakdong waterways to reflect domestic water body properties discovered by Sentinel-1 satellite radar imagery. We created a document with exact data annotation criteria for many situations. After the dataset was processed, U-Net, a deep learning model, analyzed water body detection results. The results from applying the learned model to water body locations not involved in the learning process were studied to validate soil water body monitoring on a national scale. The analysis showed that the created water body area detected water bodies accurately (F1-Score: 0.987, Intersection over Union [IoU]: 0.955). Other domestic water body regions not used for training and evaluation showed similar accuracy (F1-Score: 0.941, IoU: 0.89). Both outcomes showed that the computer accurately spotted water bodies in most areas, however tiny streams and gloomy areas had problems. This work should improve water resource change and disaster damage surveillance. Future studies will likely include more water body attribute datasets. Such databases could help manage and monitor water bodies nationwide and shed light on misclassified regions.

Purpose: Little is known about the dieting experiences of obese adolescent boys, as the majority of studies on obesity in children and adolescents have included only girls. This qualitative study was designed to explore the ways in which male middle school boys attach subjective meanings to their obese bodies, and experience dieting practices in their everyday lives. Methods: Fifteen obese boys aged 14 to 16 were interviewed via in-depth, face-to-face interviews. All interview data were audiotaped, transcribed, and analyzed using thematic analysis. Results: Having a large build and increased strength that prevented bullying by peers had positive meanings participants attributed to their obese bodies. However, negative meanings existed as well, including feeling heavy and having no physical endurance, having a clammy and odorous body, and being bullied and vulnerable to disease. With respect to dieting experiences, multiple positive and negative subthemes were identified. Conclusion: The findings of this study show the intersection between adolescence and everyday life challenges for obese middle school boys in the Korean culture. Further, recommendations for healthcare professionals include a gender-specific approaches when intervening and planning programs for obese adolescents.

This article examines the existing literature on the intersection of care and migration in Europe and the potential contributions of the Korean case. The paper reviews the three bodies of research: care, migration and their intersections. When defined as social reproductive labour, the concept of care not only captures individual/family level of experiences but it can also be an effective tool to analyse the diversity of the welfare state and the path of its evolution. Furthermore, in the context of globalisation and international migration, the concept of care can help overcome so-called 'the methodological nationalism' in the welfare state research. Accumulated evidence shows that only by applying a transnational perspective to the relationship between such social realities as class, gender and race, can we properly examine the dynamics of care distribution. Existing care-migration nexus research has found a widely observed trend of the 'migrantisation of care' in European welfare states; however, the actual modality of care-migration intersection varies reflecting historical and institutional contexts. This is why care-migration nexus research must go beyond the well-known welfare regime types. The Korean case can expand the geographical coverage and theoretical applicability of the intersection research by including a new welfare state regime type (productivist or developmental welfare states) and new patterns of migration (co-ethnic migration and marriage migration) which were rarely dealt with in this scholarship.

Since the release of Meta's Segment Anything Model (SAM), a large-scale vision transformer generation model with rapid image segmentation capabilities, several studies have been conducted to apply this technology in various fields. In this study, we aimed to investigate the applicability of SAM for water bodies detection and extraction using the QGIS Geo-SAM plugin, which enables the use of SAM with satellite imagery. The experimental data consisted of Compact Advanced Satellite 500 (CAS500)-1 images. The results obtained by applying SAM to these data were compared with manually digitized water objects, Open Street Map (OSM), and water body data from the National Geographic Information Institute (NGII)-based hydrological digital map. The mean Intersection over Union (mIoU) calculated for all features extracted using SAM and these three-comparison data were 0.7490, 0.5905, and 0.4921, respectively. For features commonly appeared or extracted in all datasets, the results were 0.9189, 0.8779, and 0.7715, respectively. Based on analysis of the spatial consistency between SAM results and other comparison data, SAM showed limitations in detecting small-scale or poorly defined streams but provided meaningful segmentation results for water body classification.
