Objective: This study investigated the clinical details and usage of Sa-am acupuncture in Korean medicine clinics and explored how practicing Korean medicine doctors(KMDs) think about Sa-am ***: We conducted a questionnaire-based survey of KMDs who utilize Sa-am acupuncture in their practice. The study comprehensively investigated issues related to clinical application of Sa-am acupuncture, needling techniques used during treatment, training methods, and directions for its future ***: We analyzed 572 responses. An average of 50% of the patients visiting Korean medicine clinics were receiving Sa-am acupuncture. The most prevalent indication for Sa-am acupuncture use was digestive disorders. The patients' appetite level and digestive function were most frequently used indicators for selecting acupuncture points. Regarding prescription compositions, jung-Gyuk formulas were more frequently used than Seung-Gyuk formulas. Inserting the needle along the flow of the channel or against the flow of the channel was most popular. The acupuncture style most frequently used in combination with Sa-am acupuncture was Ashi point acupuncture. Strengths of Sa-am acupuncture included its versatility, easy application, and good outcomes. Limitations included the lack of rigorous education and training programs,difficulty in applying the principles for beginners, and insufficient clinical research ***: In clinics where Sa-am acupuncture is available, KMDs were providing Sa-am acupuncture to about half of their patients. Practitioners were not using all of the tonification and sedation techniques which may be due to time constraints or simply a lack of necessity. Sa-am acupuncture demonstrated high utility in clinical practice and high satisfaction based on the efficacy and safety. More training programs and high-quality research are needed to help expand the use of Sa-am acupuncture.

Porous FeS nanofibers with numerous nanovoids for use as anode materials for sodium-ion batteries were prepared by electrospinning and subsequent sulfidation. The post-treatment of the as-spun Fe（acac）3-polyacrylonitrile composite nanofibers in an air atmosphere yielded hollow Fe2O3 nanofibers due to Ostwald ripening. The ultrafine Fe2O3 nanocrystals formed at the center of the fiber diffused toward the outside of the fiber via Ostwald ripening. On sulfidation, the Fe2O3 hollow nanofibers were transformed into porous FeS nanofibers, which contained numerous nanovoids. The formation of porosity in the FeS nanofibers was driven by nanoscale Kirkendall diffusion. The porous FeS nanofibers were very structurally stable and had superior sodium-ion storage properties compared with the hollow Fe2O3 nanofibers. The discharge capacities of the porous FeS nanofibers for the Ist and 150th cycles at a current density of 500 mA.g-1 were 561 and 592 mA.h-g-1, respectively. The FeS nanofibers had final discharge capacities of 456, 437, 413, 394, 380, and 353 mA-h.g-1 at current densities of 0.2, 0.5, 1.0, 2.0, 3.0, and 5.0 A.g-1, respectively.
