Dear Editors,In the article“Serum Iron Overload Activates the SMAD Pathway and Hepcidin Expression of Hepatocytes via SMURF1”,Ning Zhang et *** the molecular mechanisms linking serum iron overload to hepcidin expression,emphasizing the role of SMURF1 as a pivotal regulator of the bone morphogenetic proteins(BMP)/SMAD pathway in response to holo-transferrin induction.1 This research is significant given hepcidin’s crucial role in iron homeostasis and the pathophysiology of iron overload disorders,such as hereditary hemochromatosis.

Tourism-Oriented Cultural Product Design: A Case Study of Yami Culture in Lanyu

引用

Open Journal of Applied Sciences 2024年第9期14卷 2506-2514页

作者： Hung-Cheng Tsai Yuhsiu Liu Chung-Ming Tsai department of Industrial Design National Kaohsiung University of Science and Technology Kaohsiung City

Due to the prevalence of modern commerce and mainstream culture, many indigenous cultures around the world are rapidly diminishing. These cultures, with their unique primitiveness distinct from modern culture, often attract tourists. This study integrates the indigenous Yami culture of Lanyu Island, Taiwan Region, into innovative designs from the perspective of tourists’ understanding of the local culture. In this way, tourists can experience the harmonious coexistence of the Yami tribe and nature, while these culturally rich products foster deeper experiential and emotional resonance. This study employs the Mandala thinking method for concept expansion and the Osborn checklist method for the analysis and transformation of design elements. Subsequently, designers were invited to conduct on-site travel experiences, leading to the creation of a series of Yami cultural products. Through the evaluation and validation of cultural product assessment indicators, functional commercialized products were ultimately produced. This study aims to establish a design process for cultural products through this design case. It seeks to help users recall their Lanyu Island travel experiences and appreciate the often-overlooked cultural beauty, thereby raising awareness of cultural preservation.

A new steganographic method by pixel-value differencing(PVD)using general quantization ranges of pixel pairs’difference values is *** objective of this method is to provide a data embedding technique with a range table with range widths not limited to powers of 2,extending PVD-based methods to enhance their flexibility and data-embedding rates without changing their capabilities to resist security ***,the conventional PVD technique partitions a grayscale image into 1×2 non-overlapping *** entire range[0,255]of all possible absolute values of the pixel pairs’grayscale differences in the blocks is divided into multiple quantization *** width of each quantization range is a power of two to facilitate the direct embedding of the bit information with high embedding *** using power-of-two range widths,the embedding rates can drop using conventional embedding *** contrast,the proposed method uses general quantization range widths,and a multiple-based number conversion mechanism is employed skillfully to implement the use of nonpower-of-two range widths,with each pixel pair being employed to embed a digit in the multiple-based *** the message bits are converted into a big multiple-based number whose digits can be embedded into the pixel pairs with a higher embedding *** experimental results showed the feasibility of the proposed method and its resistance to security *** addition,implementation examples are provided,where the proposed method adopts non-power-of-two range widths and employsmultiple-based number conversion to expand the data-hiding and steganalysis-resisting capabilities of other PVD methods.
