Objectives: This study aimed to determine the effects of Korean medical treatment on a patient with compression fractures.Methods: The patient was treated with herbal medicine and acupuncture for 51 days. Symptom changes were measured using the Numerical Rating Scale (NRS), Range of Motion (ROM), Oswestry Disability Index (ODI), and European Quality of Life Five Dimensions (EQ-5D) Scale.Results: The NRS score for lower back pain decreased from 7 to 3, and the ODI score decreased from 51.11 to 22.22. Range of motion (ROM) increased meaningfully in flexion(from 30 to 60), Left/Right lateral bending(from 10/30 to 30/45), Left/Right rotation (from 10/30 to 30/45), and the EQ-5D score also increased from 0.506 to 0.677.Conclusion: The results indicate that Korean medical treatment may be effective for managing patients’ acute compression fractures.

Objectives The purpose of this review was to investigate clinical treatment trends of Achilles tendinopathy.Methods Clinical studies about Korean medicine treatments on Achilles tendinopathy were searched in 5 databases. The included studies were classified according to the authors, published years, study designs, purposes of study, methods, interventions outcome measures and adverse event.Results In 23 studies, total number of patients were 1,135. The included studies consist of 14 randomized controlled trials (RCT), 5 non-RCT, 2 retrospective study and 2 case reports. Patients were conducted with 9 kinds of treatment, which is acupuncture, electro-acupuncture, pharmacopuncture, acupotomy, moxibustion, cupping, Chuna, herbal medicine, physiotherapy. Most studies used visual analogue scale as primary outcome. Conclusions Based on the results of the collected studies, the use of Korean medicine treatment on Achilles tendinopathy seem to be effective. Despite the large number of RCTs, the level of research cannot be guaranteed, so it is considered that more rigorous researches are needed in future studies.

This study reports on the effectiveness of Korean traditional medicine treatment on a patient with right hip pain caused by obturator nerve entrapment due to ganglion cyst. The patient had been misdiagnosed for a stenosis at the other hospital, but he got a different diagnosis this time with the examination. The patient was treated with Korean traditonal medicine, which includes pharmacopuncture, acupuncture, manual treatment (Chuna), and herbal medicine. Numerical rating scale (NRS), Oswestry Disability Index (ODI) and Euroqol five dimension (EQ-5D) index were used as a objective tool for evaluating the patient's symptoms. After treatment, NRS and ODI were decreased, while EQ-5D index was increased. This study suggests that a combined Korean traditional medicine may be effective in reducing symptoms related to obturator nerve entrapment.

Carbon fiber-reinforced polymer composites employed in practical aerospace applications are subjected to harsh temperature changes and preloads (PLs) simultaneously. Thus, it is important to analyze the mechanical behavior of carbon fiber/polyether-ketone-ketone (CF/PEKK) composites under such conditions. Therefore, this study first performed bending tests on CF/PEEK samples at room temperature (RT), 80[Formula: see text]C, and 120[Formula: see text]C. Subsequently, bending tests were performed on CF/PEEK samples preloaded with 30%, 50%, and 70% of the ultimate load for 24 h and 72 h. Finally, bending tests were conducted on CF/PEKK samples subjected to both temperature and PL variations. The results show that as temperature increased from RT to 120[Formula: see text]C, the strain values increased, but the modulus ([Formula: see text]) and strength ([Formula: see text]) decreased. As PL increased, the flexural stress, [Formula: see text], and strain ([Formula: see text]) decreased. The samples preloaded with 30% of the ultimate load at 80[Formula: see text]C had the highest [Formula: see text], [Formula: see text], and [Formula: see text] values. However, the [Formula: see text], [Formula: see text], and [Formula: see text] values at 120[Formula: see text]C were only slightly lower than those at 80[Formula: see text]C. This proves that preloaded CF/PEKK composites maintain their high strength, toughness, and plastic behavior at high temperatures, and thus, they are suitable for aerospace applications.
