Body mass index and self-rated health in East Asian countries: Comparison among South Korea, China, Japan, and Taiwan

20 Sep 2024  |  journals.plos.org
The study investigates the relationship between body mass index (BMI) and self-rated health (SRH) across four East Asian countries: South Korea, China, Japan, and Taiwan. It finds that the relationship between BMI and SRH varies significantly among these countries, influenced by their unique socioeconomic and cultural contexts. In South Korea and Japan, higher BMI is associated with poorer SRH, while in China, underweight individuals report poorer SRH. Taiwan shows no significant relationship between BMI and SRH. The study highlights the importance of considering local socioeconomic and cultural factors when designing health promotion programs.

5,20-Diheterohexaphyrins: metal-template-free synthesis and aromaticity switching

15 Sep 2024  |  pubs.rsc.org
The article discusses the synthesis of 5,20-Diheterohexaphyrins without the use of metal templates and explores the switching of their aromaticity. The research is published in Chem. Commun. by authors M. Umetani, J. Kim, T. Tanaka, D. Kim, and A. Osuka.

Gender differences in the impact of retirement on depressive symptoms among middle-aged and older adults: A propensity score matching approach

03 Aug 2024  |  journals.plos.org
Retirement impacts depressive symptoms differently by gender among middle-aged and older adults in Korea. The study found that retired males exhibited higher CES-D10 scores, indicating increased depressive symptoms, while females showed no significant change. The findings suggest that retirement may be more stressful for males due to traditional gender roles and weaker social security systems in Korea. The study emphasizes the need for mental health intervention programs for retired men.

A meso–meso β‐β β‐β Triply Linked Subporphyrin Dimer

12 Jun 2024  |  Wiley Online Library
The article discusses the synthesis and characterization of a meso–meso β‐β β‐β triply linked subporphyrin dimer. The research was conducted by a team of scientists from Kyoto University and Yonsei University, focusing on the molecular structure and spectroscopic properties of the dimer.

Covalent-Frameworked 2D Crown Ether with Chemical Multifunctionality

08 May 2024  |  pubs.acs.org
A novel 2D crystalline framework named C2O, primarily composed of carbon and oxygen, has been synthesized and characterized. It features crown ether holes and demonstrates significant chemical stability and catalytic activity for CO2 fixation with epoxides. The C2O framework activates KI, enhancing the nucleophilicity of I– and resulting in high CO2 conversion rates. Modified versions of the framework, C2O-AGE and C2O-EEA, show even higher conversion rates, indicating the framework's potential for creating materials with diverse functionalities suitable for various applications.

Regioselectively Halogenated Expanded Porphyrinoids as Building Blocks for Constructing Porphyrin–Porphyrinoid Heterodyads with Tunable Energy Transfer

12 Apr 2024  |  pubs.acs.org
The study focuses on the synthesis of regioselective halogenated isomers of neo-confused isosmaragdyrin and their use as building blocks for constructing multichromophoric porphyrinoids. These heterodyads exhibit highly efficient energy cascade from porphyrin to isosmaragdyrin, with energy transfer processes and rates dependent on the linking sites. The research provides opportunities for developing new materials for optoelectronic applications.

Vision AI System Development for Improved Productivity in Challenging Industrial Environments: A Sustainable and Efficient Approach

25 Mar 2024  |  mdpi.com
The study presents a development plan for a vision AI system aimed at enhancing productivity in industrial environments with challenging environmental control. A mobile robot, SPOT, developed by Boston Dynamics, was used to obtain high-quality learning and inspection images. The proposed AI system architecture addresses challenges in applying AI technology at industrial sites, demonstrated through experimentation and application at Hyundai Motor Company's Singapore plant. The research was supported by Hyundai Motor Company and aimed to improve real-time visual inspection of manual assembly processes in automobile manufacturing.

Nonlinear Finite Element Model for Bending Analysis of Functionally-Graded Porous Circular/Annular Micro-Plates under Thermomechanical Loads Using Quasi-3D Reddy Third-Order Plate Theory

02 May 2023  |  MDPI
A nonlinear finite element model for axisymmetric bending of micro circular/annular plates under thermal and mechanical loading was developed using quasi-3D Reddy third-order shear deformation theory. The model accounts for material variation, porosity distributions, and geometrical nonlinearity, utilizing modified couple stress theory for strain gradient effects. The study investigates the effects of material and porosity distribution, microstructure-dependency, geometric nonlinearity, and boundary conditions on the bending response of functionally-graded porous microplates under thermomechanical loads.
