No full textBesides the noble physical appearance of gold and silver, their novel chemical properties attracted the modern technology for various industrial, chemical and biological uses including medical applications. The widespread use of gold and silver, however, can cause potential hazards to our environment. Therefore, suitable detection methods are a prerequisite for the evaluation of their harmful effects as well as for studying their beneficial biological properties. Due to the several advantages over the conventional analytical methods, the fluorescence detection of gold and silver has become an active research area in recent years. In this review, we provide an overview of the reported fluorescentdetection systems for gold and silver species, and discuss their sensing properties with promising features. The future scope of developments in this field of research is also mentioned.17
자기폐색 물체의 2D커브로부터의 3D 모델링
No full textIn this paper, we propose a method for reconstructing a 3D object (or a set of objects)
from a 2D drawing provided by a designer. The input 2D drawing consists of a set of contours that
may partially overlap each other or be self-overlapping. Accordingly, the resulting 3D object(s) may
occlude each other or be self-occluding. The proposed method is composed of three major steps: 2D
contour analysis, 3D skeleton computation, and 3D object construction. Our main contribution is to
compute the 3D skeleton from the self-intersecting 2D counterpart. We formulate the 3D skeleton
construction problem as a sequence of optimization problems, to shape the skeleton and place it in the
3D space while satisfying C1-continuity and intersection-free conditions. Our method is mainly for a
silhouette-based sketching interface for the design of 3D objects including self-intersecting objects
3D body reconstruction from photos based on range scan
No full textWe present a data-driven shape model for reconstructing human body models from one or more 2D photos. One of the key tasks in reconstructing the 3D model from image data is shape recovery, a task done until now in utterly geometric way, in the domain of human body modeling. In contrast, we adopt a data-driven, parameterized deformable model that is acquired from a collection of range scans of real human body. The key idea is to complement the image-based reconstruction method by leveraging the quality shape and statistic information accumulated from multiple shapes of range-scanned people. In the presence of ambiguity either from the noise or missing views, our technique has a bias towards representing as much as possible the previously acquired 'knowledge' on the shape geometry. Texture coordinates are then generated by projecting the modified deformable model onto the front and back images. Our technique has shown to reconstruct successfully human body models from minimum number images, even from a single image input

The moderating role of cultural orientation on emotional and behavioral outcomes of helping others
No full textThis research challenges the common notion that people always feel good after helping others. Using a cross-cultural lens, it refines our understanding of previously documented emotional boost after helping. Helping others in individualistic cultures has been conceptualized more as a choice (vs. obligation), whereas in collectivistic cultures it is conceptualized more as an obligation (vs. choice). Previous literature on the emotional consequences of helping behavior, however, has not considered these culturally distinct conceptualizations. I argue that these culturally shaped conceptualizations of helping behavior (choice vs. obligation) will underlie distinct emotional outcomes that vary as a function of an individual’s cultural orientation. Further, I demonstrate how these emotional outcomes may be reflected in subsequent consumer behaviors (e.g., advertisement evaluations and music preferences), suggesting that these emotional consequences are associated with managerially important outcomes such as consumption for mood management.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2020-05-01The student, Hyewon Cho, accepted the attached license on 2018-04-18 at 12:12.The student, Hyewon Cho, submitted this Dissertation for approval on 2018-04-18 at 12:18.This Dissertation was approved for publication on 2018-04-18 at 14:55.DSpace SAF Submission Ingestion Package generated from Vireo submission #12350 on 2018-08-31 at 17:29:57Made available in DSpace on 2018-09-04T20:47:23Z (GMT).

Luffa cylindrica -inspired powerless micropump: long-term, high-flow operation and energy-generation application
No full textA biomimetic micropump inspired by Luffa cylindrica enhances passive fluid transport by integrating a hierarchical porous aerogel and flow resistors, enabling controlled and sustained operation for microfluidics and energy generation applications.Powerless micropumps are in increasing demand for applications requiring portability, simplicity, and long-term operation. However, several existing passive pumps have limitations such as sustained high flow rates and extended operational periods. Inspired by the unique structural characteristics of Luffa cylindrica , this study aims to develop a biomimetic micropump capable of long-term and high-flow operation. By examining the water transport mechanisms in a hierarchical porous structure, we designed and fabricated micropumps that replicate these mechanisms. A key aspect of this design is the integration of flow resistors, which enables precise control over the absorption rates and extend the pumping duration. The cone-shaped agarose aerogel (AAG) micropump operates for over 930 min with an average flow rate of 5.6 μl min −1 , demonstrating significant longevity. The agarose superabsorbent polymer aerogel (ASAG) micropump, while having a shorter operational duration of approximately 620 min, exhibited a significantly higher average pumping rate of 13.2 μl min −1 . This study highlights the potential of bio-inspired designs for advancing efficient and powerless pumping systems. The proposed micropump shows promise for applications in microfluidic devices and reverse electrodialysis systems, where continuous and sustainable fluid transport is essential.A biomimetic micropump inspired by Luffa cylindrica enhances passive fluid transport by integrating a hierarchical porous aerogel and flow resistors, enabling controlled and sustained operation for microfluidics and energy generation applications.Powerless micropumps are in increasing demand for applications requiring portability, simplicity, and long-term operation.

Increasing access to oral healthcare for marriage-immigrant women in South Korea: programme design to policy recommendation
No full textObjectives: To examine oral health status and access to dental care among marriage-immigrant women (MIW) in South Korea (Korea). Materials and methods: We analysed patients’ demographic information and access to dental services through the ‘Family-Love Dental Program’ and compared them with Korean oral health surveillance data. The ‘Family-Love Dental Program’ resulted from a partnership among the Korean Ministry of the Gender Equality and Family, Seoul National University Dental Hospital, and Cigna Insurance Company (registered as ‘LINA’ in South Korea) to increase access to oral health for MIW from 2010 to 2016. Results: Over the programme duration, 1,944 MIW underwent dental examination and 1598 MIW received dental treatment. More than two-thirds of MIW (69.5%) receiving dental services were aged between 20 and 39 years. In 2016, the proportion of untreated dental caries among MIW was 54.8%, which was significantly higher than that of untreated dental caries among Korean women within the same age group (24.9%). Over the programme duration, 501 MIW (25.8%) underwent final restoration, and advanced care was provided at the Seoul National University Dental Hospital. Conclusion: MIW have a significantly higher number of dental caries than Korean women within the same age group. Future programmes and policies should consider specific barriers that will promote oral health parity for MIW and their children
International and national frameworks, guidelines, recommendations, and strategies for maternal tobacco prevention and cessation: A scoping review protocol
No full textTobacco use during and around pregnancy can significantly increase the risk of stillbirth, congenital disabilities, premature birth, and low-weight birth. To establish maternal tobacco prevention and cessation frameworks for primary care and dental providers and to facilitate cross-national learning, this scoping review aims: 1) to analyze the body of literature on maternal tobacco prevention and cessation frameworks, guidelines, recommendations, and strategies at the international and national level; 2) to identify common core elements; and 3) to identify gaps in the literature, and propose future initiatives and policy development directions. A systematic database search based on the JBI methodology and corresponding PRISMA-ScR guidelines will be conducted from January 2015 to August 2023. Searches in different databases will be combined with an expert survey among the members of the World Federation of Public Health Associations (WFPHA) – Oral Health, Tobacco Control, and the Women, Adolescent, and Children’s Working Groups to evaluate the search outcomes and add maternal tobacco prevention and cessation frameworks, guidelines, recommendations, or strategies. Using a systematic review tool to support the screening, two independent reviewers will screen the titles and abstracts of all articles, in order to include the relevant ones for full-text screening, and an independent third author will resolve conflicts, if there is any discrepancy between the two independent reviewers’ search. After a full-text review, data extraction will be conducted for analysis. Descriptive analyses include the publication year, country, legal quality, and target group addressed. A narrative synthesis will describe the scope and content of the frameworks, guidelines, recommendations, and strategies. The scoping review will serve as a stepping-stone to creating a WFPHA policy resolution on tobacco prevention and cessation framework for women of childbearing age led by the WFPHA Oral Health, Tobacco Control and the Women, Adolescent, and Children’s Working Group members. This WFPHA policy resolution ‘Maternal Tobacco Cessation and Prevention Recommendations for Primary Care Providers and Dental Providers’ will be forwarded to the WFPHA General Council and the General Assembly for approval and will be disseminated to the WFPHA public health association members. Ultimately, this recommendation will be used by each national public health association to consider integrating it into their maternal health strategy
