The purpose of this study was to evaluate the effects of using cervical spinal stabilization exercise for the improvement of pain intensity, cervical range of motion, neck disability index, reposition sense, muscle tenderness with chronic neck pain in private security. For 21 patients diagnosed with chronic cervical pain and divided into cervical spinal stabilization exercise group and postural correction exercise group. Each exercise was conducted for 8 weeks. Pain and neck disability index were measured before and after exercise using the visual analogue scale(VAS) and the neck disability index(NDI). Range of motion were measured electronic goniometer, muscle tenderness of upper trapezius ad sternocleidomatoid were measured algometer, reposition sense were measured reposition panel before and after exercise. After 8 weeks of exercise, the cervical stabilization exercise group pain and neck disability were significantly decreased(p<0.05). Also there was significant difference in both group(p<0.05). In addition, range of motion, muscle tenderness reduce rate, reposition sense were significantly increase as compared to the pre-post exercise in cervical stabilization exercise group(p<0.05). But there was no significantly difference in postural correction group before and after exercise(p>0.05). And there was significantly increase more cervical stabilization exercise group than postural correction exercise group in range of motion, muscle tenderness reduce, reposition sense. In summary, cervical spinal stabilization exercise is more effective in improving cervical range of motion, muscle pain, reposition sense in private security on chronic cervical pain patients, in reducing patients' pain and disability. It is an effective treatment to aid rehabilitation in these cases.

Chibby family member 2 (CBY2), also known as SPERT or NURIT, is a gene with Chibby-like super family domain, whose function is not well known. In this study, the quail CBY2 gene was cloned, its sequences were analyzed, and its role in the myogenesis of QM7 quail muscle cells was characterized. Quail CBY2 has 978 nucleotides, which are translated into 325 amino acids, and the amino acid sequences are highly similar to those of chicken CBY2. Avian CBY2 diverted from mammalian CBY2 during early evolutionary history. According to the protein domain prediction analysis, quail CBY2 has a Chibby-like superfamily domain consisting of 83 amino acids at the N-terminal of the protein, although compared to mammalian CBY2, many of the amino acids were different. CBY2 was highly expressed in the adipose tissue and moderately expressed in the liver, heart, and kidney, whereas rarely expressed in the muscle tissue in quail. To characterize the role of CBY2 in myogenesis, CBY2 was overexpressed in QM7 cells. The overexpression of CBY2 inhibited myotube formation as shown that the myotube area was approximately only 25% that of the control. Taken together, quail CBY2 has a Chibby-like superfamily domain and inhibits myogenesis. Further studies should focus on the identification of the inhibitory mechanism of CBY2 on myogenesis.

The purpose of study is to investigate the difference of the daN force applied during the examination using Telos Device and the degree of fluctuation of anterior cruciate ligament according to the individual differences of the muscles involved in knee stability. The examination was done by the Lachman test using Telos Device and the changes of anterior cruciate ligament were measured by varying the force of 0. 15, 30 daN on each right and left side and the force of 30 daN after the bruce protocol. Computed tomography (CT) was used to measure muscle mass. As a result of measuring the degree of fluctuation of the anterior cruciate ligament according to the change of the force applied to the Telos Device, there was a statistically significant difference in the knee fluctuation when 15 daN and 30 daN were applied on both right and left. Also, it is analyzed that the degree of fluctuation of anterior cruciate ligament varies according to the difference of individual's muscle mass. Therefore, it is considered that the force applied to the Telos Device should be changed according to the difference of individual's muscle mass.

In this study, we investigated whether p-anisaldehyde (PAA), the main component of essential oils derived from anise seeds, influences the differentiation of mouse C2C12 myoblasts. Cells were induced to differentiate over 5 days using a differentiation medium with or without PAA (50 or 200 mg/mL). Myotube length and diameter were measured, and the expressions of myogenic markers (myoblast determination protein 1, myogenin, myocyte enhancer factor 2, muscle creatine kinase, and myosin heavy chain) and atrophy-related genes (atrogin-1 and muscle ring finger-1 [MuRF-1]) were assessed by quantitative real-time polymerase chain reaction. Additionally, protein kinase B (Akt) phosphorylation was monitored by western blotting. PAA significantly induced the formation of smaller and thinner myotubes and reduced myogenic marker expression. Furthermore, PAA increased the expressions of atrogin-1 and MuRF-1 and simultaneously reduced Akt phosphorylation. Our findings indicate that PAA inhibits the myogenic differentiation of C2C12 cells by reducing the phosphorylation and activation of Akt.

Stomatognathic system is a complex one that is composed of TMJ, neuromuscular system, teeth and connective tissue, and all its components are doing their parts to maintain their physiological relationships. Mandible, in particular, performs various functions such as mastication, speech, and deglutition, the muscular activities that determine such functions are signalled by numerous types of proprioceptors that exist in periodontal membrane, TMJ, and muscles to be controlled by complicated pathways and mechanics of peripheral and central nervous system. Orthodontic treatment, especially when accompanied by orthognathic surgery, brings dramatic changes of stornatognat is system such as intraoral proprioceptors and muscle activities and thus, changes in patterns of mandibular function result The author tried to analyze changes in patterns of mandibular movement and physiologic activities of surrounding muscles in Skeletal Class III ortlrognathic surgery patients who presently show a great increase in numbers. The purpose of this study was to draw some objective guidelines in evaluating funclierual aspects of orthognathic surgery patients. Mandibular functional analysis using Biopak was performed for skeletal Class III prognathic patients who underwent IVRO(lntraoral Vertical Ramus Osteotmy), and the following results were obtained: 1. Resting EMG was greater in pre-surgical group than the control group, and it showed gradual decrease after the surgery. Clenching EMG of masseter and anterior temporalis of pre-surgical group was smaller than those of control group, they also increased post-surgically, and significant difference was found between pre-surgical and post-surgical(6 months) groups. 2. Resting EMG of anterior ternporalis was greater than that of all the other muscles, but there was no significant difference. Clenching EMG of anterior temporalis and masseter were greater than those of the other muscles with statistical difference. In swallowing, digastric muscle showed the highest EMG with statistical significance. 3. Limited range of mandibular movement was shown in pre-surgical group. Significant increase in maximum mouth opening was observed six months post-surgically, and significant increase in protrusive movement was observed three months post-surgically.

Lumbar stabilization exercise is a popular exercise method in recent clinicians, as it strengthens muscles around the spine and abdominal muscles, but there is a lack of research on the effects of pulmonary function and respiratory pressure. So, this study examined whether abdominal bracing exercise, a typical lumbar stabilization exercise, was effective in pulmonary function and respiratory pressure. In this study, a total of 20's 40 subjects were recruited and randomly divided into an abdominal bracing exercise group(n=20) and control group(n=20). Abdominal exercise group underwent 25 minutes of exercise. Pulmonary function and respiratory pressure values were measured to analyze respiratory function. As a results of the experimental group, there were significant improvements in FVC, FEV1, PEF and MEP(p<.05) and there was a significant difference in the comparison between groups, except the MIP. These results suggest that abdominal bracing exercise can be presented as effective exercises to improve respiratory function.

EMSCT (Electrical Muscle Stimulation Conductive Textile) is an electrical muscle stimulation pad that can compensate for ease of use and comfort, which are disadvantages of conventional hydrogel pads used in electrical muscle stimulation (EMS). With the concentration with SWCNT (Single-Walled Carbon Nanotube) and the number of impregnation processes, EMSCT was tested by giving conductivity to five fabrics (radirons, neoprene, spandex cushions, poly100%, and vergamo). The padding process with SWCNT was performed, and the alternating current measurement indicated that the most similar alternating current with hydrogel was the Vergamo fabric of SWCNT:=2:1. Furthermore, the usability evaluation of convenience, usability, and psychological satisfaction results in increased usability of EMSCT compared with conventional hydrogel pads.
