Objectives : The purpose of this study is to investigate various application methods of focused ultrasound and apply them to clinical use in Korean medicine. Methods : Search was performed using the search engines of electronic databases, including PubMed, ScienceDirect, Cumulative Index to Nursing and Allied Health Literature (CINAHL), ScienceON, Oriental Medicine Advanced Searching Integrated System (OASIS), China National Knowledge Infrastructure (CNKI), Wanfang Data, Japan Science Technology Information Aggregator, Electronic (J-STAGE) and Citation Information by NII (CiNii), from inception to July 2023 without language limitation. Inclusion criteria were clinical studies including randomized controlled trials (RCTs), and animal experimental studies related with focused ultrasound treatments for acupoints or meridian sinews. Results : Total 17 papers, 7 for RCT, 6 for in vivo animal studies, and other experimental studies, were finally selected. Indications used in studies were shoulder pain, back pain, chronic back pain, and degenerative knee arthritis. In experimental studies, studies on animal models of hypoxic ischemic brain damage and hyperlipidemia were also conducted. As for the acupoints, LR3, LI4, and ST36 were used in clinical studies and, in animal experimental studies, GV20, KI1, and ST36 were used. As for the dose, 4 studies below 3 W/cm² and 3 studies in the range of 0.625 to 5 W/cm² in clinical studies, and all studies did not exceed 5 W/cm². In animal experimental studies, 0.5 W/cm², 2 W/cm², 7.5 WW/cm², 15 W/cm², 10~20 W/cm² were used. In all three studies describing the penetration depth during irradiation, it was less than 1 cm. Conclusions : We suggest that focused ultrasound is an appropriate treatment tool for stimulating the acupoints to transfer heat energy. Future studies with rigorous and well-designed RCTs for various diseases will be required to ascertain the focused ultrasound stimulate acupoints or meridian sinews.

The study investigated the relationship between vitamin D status and lifestyle risk factors in office workers. A total of 515 office workers(336 men and 179 women) aged 30 years or older were voluntarily recruited from S-city. Along with serum vitamin D levels, lifestyle risk factors including obesity index, physical fitness, metabolic risk factors, lipids profile and sedentary behavior were measured using standardized protocols. Subjects were classified as deficiency (<20ng/mL), insufficiency (20-29ng/mL), and sufficiency (≥30ng/mL) based on serum vitamin D levels. Linear contrast analysis using one-way ANOVA showed significant linear decreases in mean body fat (p=.030) and sedentary behavior (p<.001) and significant linear increases in skeletal muscle (p=.037), cardiorespiratory fitness (p<.001) and HDL-C (p=.013) across incremental serum vitamin D levels. Compared with the low cardiorespiratory fitness group, the high cardiorespiratory fitness group had a significantly higher odds ratio (men OR=2.144, p=.042, women OR=1.971, p=.045) for having vitamin D insufficiency or deficiency even adjustment after age. Compared to the shortest sitting time group, the longest sitting time group had a significantly higher odds-ratio in a group of female office workers (OR=1.262, p=.043) for having vitamin D insufficiency or deficiency even adjustment after age. The current findings of the study showed that poor physical fitness and sedentary behavior were the risk factors of low serum vitamin D levels, implying the urgent need for a healthy lifestyle modification along with vitamin D supplementation.

The purpose of this study was to analyze the amount of physical activity and body composition and to investigate physical activity according to cancer type, sex, and age among colorectal and gastric cancer survivors. A total of 354 participants who were colorectal (n=185) and gastric (n=169) cancer survivors had completed all treatment less than 4 years ago at Y university hospital between June 2014 and April 2015. The Global Physical Activity Questionnaire (GPAQ) was used to measure time and intensity of physical activity according to the different types of activity. The colorectal cancer survivors were significantly higher in body mass index, waist circumference, percent body fat, blood pressure, and the prevalence of diabetes compared to gastric cancer survivors. In addition, the results showed that only 26.5% of colorectal cancer survivors met American College of Sports Medicine (ACSM) guidelines (at least of 150 min of moderate intensity of higher physical activity per week) for physical activity, compared with 41.4% of gastric cancer survivors. Additionally, only 13.6% of colorectal and gastric cancer survivors met strength exercise guidelines. The male cancer survivors were significantly higher in moderate physical activity, participation in resistance exercise, and sedentary behaviors compared to female cancer survivors. In additions, less than 65 years cancer survivors were higher in strenuous intensity exercise and moderate physical activity compared to more than 65 years cancer survivors. The alternative for promoting physical activity participation rates of colorectal and gastric cancer survivors should be presented.

In predicting vascular disease, this study attempted to identify changes in the carotid intima-media thickness in patients who underwent carotid artery ultrasonography and hematological tests and to find out the effect of risk factors on the expression of atherosclerotic plaque. A retrospective analysis was conducted on 469 healthy adults who visited the hospital for the purpose of medical examination and performed carotid artery ultrasonography. As a result, carotid intima-media thickness, age, body mass index, waist circumference, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and glucose were analyzed as significant predictors of atherosclerotic plaque (p<0.001). The risk ratio was calculated based on the cut off value of the risk factors of the atherosclerotic plaque determined through ROC curve analysis, followed by 8.06 times the carotid intima-media thickness, 7.53 times the age, 3.97 times the waist circumference and 2.02 times the glucose. Therefore, in this study it was possible to prepare a Korean standard for clinical risk factors that affect the presence of absence of atherosclerotic plaque and observation of carotid artery ultrasonography is thought to help diagnose or predict cardiovascular disease early.

The purpose of this study was to investigate effective intervention(upper thoracic mobilization and upper cervical mobilization) methods for forward head posture. 32 subjects were divided into two groups: upper thoracic mobilization(UTM) and upper cervical mobilization(UCM) on three times a week for a total of four weeks. In both groups significant difference in forward head posture pre and post test(p <.01), significant difference between the two groups (p <.05, 95% CI: .157-.341). In both groups significant difference in neck disability index pre and post test(p <.01), significant difference between the two groups (p <.01, 95% CI: 1.273-8.728). In both groups significant difference in quality of life pre and post test(p<.05), significant difference between the two groups (p <.01, 95% CI: 4.234-18.391). The results of this study showed that the UTM was more effective than that of the forward head posture. It would be possible to provide more effective interventions for patients with forward head posture and also to prevent secondary musculoskeletal disorders due to forward head posture.

Structural health monitoring for ships and offshore structures is important in various aspects. Ships and offshore structures are continuously exposed to various environmental conditions, such as waves, wind, and currents. In the event of an accident, immense economic losses, environmental pollution, and safety problems can occur, so it is necessary to detect structural damage or defects early. In this study, structural response data of multi-linked floating offshore structures under various wave load conditions was calculated by performing fluid-structure coupled analysis. Furthermore, the order reduction method with distortion base mode was applied to the structures for predicting the structural response by using the results of numerical analysis. The distortion base mode order reduction method can predict the structural response of a desired area with high accuracy, but prediction performance is affected by sensor arrangement. Optimization based on a genetic algorithm was performed to search for optimal sensor arrangement and improve the prediction performance of the distortion base mode-based reduced-order model. Consequently, a sensor arrangement that predicted the structural response with an error of about 84.0% less than the initial sensor arrangement was derived based on the root mean squared error, which is a prediction performance evaluation index. The computational cost was reduced by about 8 times compared to evaluating the prediction performance of reduced-order models for a total of 43,758 sensor arrangement combinations. and the expected performance was overturned to approximately 84.0% based on sensor placement, including the largest square root error.

Nerve conduction study (NCS) is an essential test for the diagnosis and follow-up of peripheral neuropathy. NCS can objectively quantify peripheral nerve function. NCS is affected by physiological factors such as height, age, body mass index, etc. Hence, the American Association of Neuromuscular & Electrodiagnosis Medicine (AANEM) is currently forming a Normal Data Task Force (NDTF) to present the normal value, but the number is significantly less. Currently, no research has been carried out on the correlation between nerve conduction speed and height and lower limb length in Koreans. Hence, this study sought to compare the nerve conduction velocity of the lower limbs according to the height and lower limb length. A total of 49 subjects were recruited. When the motor nerve conduction velocity and sensory nerve conduction velocity were compared according to the height and leg length, there was a statistically significant negative correlation of the peroneal and left tibial motor nerves with the height. Also, a statistically significant negative correlation was observed with the superficial peroneal sensory nerve and the sural nerve and the leg length. However, in this study, all the subject are in twentys age, whereas the NDTF is divided by age. Hence, additional studies involving subjects of various age groups are needed.

Background: The current study is the first quantitative ethnobotanical evaluation of Fateh Pur Thakyala, an unexplored area of Azad Kashmir, Pakistan. The exploration and quantification of ethnobotanical knowledge among people of the study area mainly focused during field survey. The study likely focuses on documenting and preserving the indigenous knowledge and practices related to medicinal plants in the region. A total 70 informants (45 males and 25 females) selected randomly to collect data were interviewed using semi structured questionnaire. The data like demographic characteristics of informants, methods of preparation, life form, modes of application, parts used, and ethnomedicinal uses was documented. The quantitative indices including relative frequency of citation (RFC), use value (UV), informant consensus factor (ICF), fidelity level (FL), consensus value for plant part (CPP), rank order priority (ROP), percentage respondent knowledge (PRK), were applied to analyze the collected data. Furthermore, primary data were also compared with fifteen papers published from adjoining areas by Jaccard index (JI). Results: The current study reported 135 medicinally important plants species belonging to 115 genera and 54 families. The dominating family was Asteraceae (14 sp.), followed by Fabaceae (11 sp.), Rosaceae (11 sp.), Lamiaceae (8 sp.), Moraceae (5 sp.), Solanaceae, Cyperaceae, Euphorbiaceae (4 sp.) and Poaceae, Sapindaceae, Rhamnaceae, Mrytaceae, Malvaceae (3 sp.) for each. The study revealed that there were small differences in usage of medicinal plants of different families. The herbaceous life form was dominating the study area with (79 sp.) used as herbal medicines followed by shrubs (23 sp.) and trees (33 sp.). The comparative study of for novelty of species and their uses by JI revealed 13 novel plants species which were not reported earlier from this region. Conclusions: Local inhabitants still prioritize herbal medicines as an effective way to treat a wide variety of ailments. Elders and health practitioners of the study area are well aware of indigenous knowledge about medicinal plants, but young people are not much interested in herbal practices. Thus, valuable knowledge about the use of plants is on the verge of decline. The overexploitation and seasonal fires are major threats for medicinal flora in the area.
