(1) Background: With the emergence of various super bacteria, interest in antibacterial properties, drug delivery, and wound regeneration is increasing in the field of surgical materials. There are many studies on surgical sutures, but not many recent ones that have studied structurally subdivided functions. Accordingly, various studies on surgical sutures were classified based on the main functions that are considered important, and studies were conducted by categorizing the latest production technology into 3D printing and electrospinning. (2) Methods: Data from the literature (n = 1077) were collected from databases such as PubMed, Harvard.edu, MDPI, Google Scholar, Web of Science, ACS, Nature, and IOP Publishing. The selected 103 papers were divided into two main groups: cutting-edge characteristics of surgical sutures and the latest technologies for manufacturing surgical sutures. (3) Results: Cutting-edge characteristics of surgical sutures were divided into four major categories: antibacterial, drug delivery, biodegradability, and wound regeneration, and examined in depth. In addition, the final technologies for manufacturing surgical sutures were divided into electrospinning and 3D printing. (4) Conclusions: The results of this study can contribute to the development of multifunctional surgical sutures that promote wound regeneration through antibacterial properties, drug elution, and biodegradability.

With the development of convergence technology, the Internet of Things (IoT), and artificial intelligence (AI), there has been increasing interest in the materials industry. In recent years, numerous studies have attempted to identify and explore multi-functional cutting-edge hybrid materials. In this paper, the international literature on the materials used in hybrid fibers and manufacturing technologies were investigated and their future utilization in the industry is predicted. Furthermore, a systematic review is also conducted. This includes sputtering, electrospun nanofibers, 3D (three-dimensional) printing, shape memory, and conductive materials. Sputtering technology is an eco-friendly, intelligent material that does not use water and can be applied as an advantageous military stealth material and electromagnetic blocking material, etc. Electrospinning can be applied to breathable fabrics, toxic chemical resistance, fibrous drug delivery systems, and nanoliposomes, etc. 3D printing can be used in various fields, such as core-sheath fibers and artificial organs, etc. Conductive materials include metal nanowires, polypyrrole, polyaniline, and CNT (Carbon Nano Tube), and can be used in actuators and light-emitting devices. When shape-memory materials deform into a temporary shape, they can return to their original shape in response to external stimuli. This study attempted to examine in-depth hybrid fiber materials and manufacturing technologies.

With the recent development of advanced industries, in addition to simple abrasions, the demand for wound dressing is gradually increasing in fields such as diabetes care. Factors affecting wound healing include pH, temperature, genetic factors, stress, smoking, and obesity, and studies on these are also increasing. In addition, studies on hydrogels, electrospun nanofibers, foams, films, plant-based materials, chitosan, gelatin, 3D printing, and chemosensors for wound healing are also increasing. However, although there are many data related to wound healing, there are not many studies that have systematically divided them into structures, materials, and monitoring through a review of the literature. Therefore, based on various studies on wound healing, wound-healing materials were classified into structures (films, foams, gauzes, and electrospun nanofibers), chemical materials, nature-based materials, and monitoring sensors, and a literature review was conducted.

Titanium exhibits substantial corrosion resistance, strength, and ductility, with a specific gravity of approximately 4.5 and a melting point of approximately 1800°C. It is currently used in aircraft parts and space development. This study considered the thermal characteristics, stealth effects of infrared thermal imaging cameras, electromagnetic shielding, and electrical conductivity of Ti-sputtered materials. Base materials of different densities and types were treated using titanium sputtering. Infrared thermal imaging showed a better stealth effect when the titanium layer was directed toward the outside. The film sample presented a better stealth effect than the fabrics did. In each of the samples subjected to titanium sputtering, when the titanium layer was directed outward, the untreated sample or exposed titanium layer showed surface temperatures lower than those of the samples with the titanium layer oriented toward the heat source. Additionally, after the titanium sputtering treatment, the films conducted electricity (low resistance) better than the fabrics did. All titanium-sputtered specimens presented reduced electromagnetic wave transmission and significantly reduced infrared transmission. These results are expected to apply to military uniforms (soldiers'' protective clothing to gain the upper hand on the battlefield), medical sensors, multifunctional intelligent textiles and etc.

The necessity for complex functionality materials is increasing due to the emergence of high-tech technologies and the deepening needs of B-to-B companies in the industry. Study on advanced multifunctional materials is also increasing due to interest in fields such as the the Internet of Things (IOT), Fourth Industrial Revolution, and artificial intelligence (AI). Nanomaterials have the advantage of having a large surface area, making it easier to express more efficient properties, and they have been widely applied recently in various fields. When designing new materials for specific applications, it is often important to control the shape, size distribution, surface properties, dispersion, and agglomeration stability of synthetic nanoparticles, as well as the elemental and nanocrystalline compositions of the materials. Nanomaterials have infinite potential, but there are not many cases of collection and structural classification. Therefore, I attempted to conduct an in-depth systematic review by categorizing nanomaterials into nanoparticles, nanoplates, nanowires, and nanorolls according to their nanostructures. Additionally, the representative materials of nanowires include CuNW (copper nanowire), AgNW (silver nanowire), and GaAsP single nanowire. Moreover, nanoroll-type materials include SWCNTs (single-walled carbon nanotubes), DWCNTs (double-walled carbon nanotubes), and MWCNTs (multi-walled carbon nanotubes). In conclusion, this study, through a systematic review, is intended to provide a cornerstone for application plans when designing cutting-edge chemosensors.

Purpose: The research aims to investigate how changes in customer purchasing behavior and the resulting psychological anxiety of beauty advisors affect their employability in the new normal era following COVID-19. Additionally, it seeks to understand the mediating role of cognitive flexibility in this relationship.Methods: To accomplish this, a questionnaire survey was administered to 600 department store beauty advisors between June 20 and July 20, 2023, and data from 555 were collected. To ensure the validity of the study, a research model was tested, using SPSS WIN 25.0. This study investigated whether psychological anxiety and changes in consumers' purchasing behavior affected department store beauty advisors' employability and etc.Results: The findings reveal that psychological anxiety significantly affect the employability of department store beauty advisors. Cognitive flexibility plays a mediating role, suggesting that higher cognitive flexibility can mitigate the negative impacts of changing consumer behaviors on employability.Conclusion: The study concludes that enhancing cognitive flexibility among beauty advisors can help them better adapt to the new normal environment, thereby improving their employability. Cosmetic businesses can leverage these insights to develop strategies that enhance their employees' cognitive flexibility and responsiveness to changing consumer behaviors and etc.
