  • Entering the twentieth century, corsets began to disappear with the tendency of concentrating on slim bodies and youth. As corsets proceeded to be discarded, they began to be internalized as a means of controlling the body; 'muscular corset' takes hold. However, the internalized corset increasingly appears to be externalized again in contemporary fashion. This study investigates how natural body is reconstructed as socio-cultural image drawing on the relationship between the signifier and signified of corset. As for the research methodology this study conducts literature survey to investigate the internalization of corset. This study proceeds to examine the subjects of fashion collections from 1980 to 2010 and samples the outfits which represent the externalization of corset through case analysis. Through the discussion of the study, the relationship of signifier and signified in the externalization of corset is argued as follows: first, by maintaining signifier and signified of the traditional corset as underwear, aggressive eroticism of corset has been observed, second, by perceiving corset as the agency of the body, fetishism of corset dissociates the function of sexual object from corset while distorting the relationship of signifier and signified, third, through embodying the notion of muscular corset literally, the ironical representation of corset as a torturing device of female body deconstructs the traditional relation of signifier and signified of corset.

  • Physical manifestations of aging due to the lack of exercise include the slowing down of motor learning, cardiopulmonary degradation, and the increasing difficulty to adapt to the environment. Aging is manifested with the lack of aerobic exercise work, decrease in muscular endurance, decline in skeletal and muscular strength, flexibility and agility, and the decrease in reaction speed and balance. Added to those are aging-related physiological changes, including the reduction of muscle bulk, increased body fat, decrease in total body water and basic metabolic rate as activities are reduced, and a decrease in cell and Lean Body Mass (LBM). These changes are known to cause problems. Interest and participation in appropriate physical activities among the elderly is needed to help them increase stamina, avoid diseases, maintain a clear intellect, and basically enable the elderly to live their daily lives as easy as possible. Therefore, physical activities are necessary for the elderly to enhance health-related factors. Special exercises should be performed for the enhancement of muscle function, muscle endurance, flexibility, agility, and balance. An accurate measurement of cardio-respiratory endurance and stamina through basic physical and cognitive characteristics of older adults is also required to ensure safety. Also, the development of a more scientific resistance exercise prescription system for the elderly is desperately needed.

  • The nerve system specific protein of Drosophila melanogaster was produced by using heads of flies as the antigen. The monoclonal antibody 6H6 recognized the disabled molecules that a kind of tyrosine kinase substrate by expres-sion cDNA library screening method. At the same time, the antibody also specifically recognized C-terminal region of disabled protein from 7427 to 8761bp by DNA sequencing. In early embryos, the localization of antigen appeared in the central nerve system. In adult flies, the antigen showed specific localization on the axon of optic nerve, cerebral nerve and thoracic nerve, and they also expressed on the muscular nerve. The molecules of disabled are expected to carry an important function in developing central nerve system. In adult flies, it is suggested that the disabled molecules have a role for muscular nerve as well as neural axon.

  • In most of the medical literature that discusses the common problem of movement in patients with cerebral lesions. This critical problem is ascribed to a mechanism involving uninhibited neural activity. The goals of neurological physical therapy are focus on reduce of muscle hypertonicity, facilitates muscle activities, and improve of performance in living environment. A variety of studies suggest that spasticity is a distinct problem and separate from the muscle weakness. It has become increasingly recognized that the major functional deficits following brain damage are largely due to negative features such as muscle weakness and loss of performance rather than spasticity. Adequate recruitment of prime mover, not release was able to carry out the movement tasks well. The strengthening exercise of spastic limbs on changes in muscle properties and performance skill, the repeated motor practice has been identified as crucial for motor recovery. This article support the concept that strengthening is an appropriate intervention to improve the quality of physical function in patients with central nervous system lesions. Further studies and therapeutic approaches should be efforts at improving motor neuron recruitment in agonist rather than reducing activity in antagonists while retraining muscle strengthening.

  • An experimental study was conducted to investigate the effects of turtle neck syndrome, so called, on muscular fatigue and muscle activity. Six subjects (males) participated and performed the prolonged casual computer work in the study. EMG signals from six muscles of the dominant neck-back region were acquired and recorded for 10 seconds at the beginning and the end of three hours computer work. EMG was recorded from six muscles by using a computerized data recording and analysis system. Power spectrum function of EMG was calculated off-line by means of a signal processing software package. Power spectrum functions were smoothed with a moving average filter of 21 points and normalized with respect to the maximal value achieved during the trials. Muscle activity and median frequencies of Sternocleidomastoid(SCM) in turtle neck posture was approximately 51%, which were less than those in normal neck posture. SCM also showed the biggest decrease in median frequency. Results will provide the insight into the neck-back injury mechanism of turtle neck patients. Furthermore, they will be helpful in developing rehabilitation programs for restoring patients' neck-back functions.

  • Purpose : This study examines the effects of pre-eccentric exercise and stretch ing to bicepsbrachii to prevent delayed onset muscle soreness and recovery of muscular function depending on the training intensity with 28 normal adults in their twenties. Methods : The subjects were divided into a control group, a group without any previous eccentric exercise, and a stretching group. Pre-eccentric exercise group conducted exercise with the intensity of 25% of maximal voluntary contraction. Pre-eccentric exercise and stretching was applied before to induce delayed onset muscle soreness and after, 24 hour post, 48 hour post, and 72 hour post. Measurements were conducted to examine pain and muscular function changes before, immediately after, and after inducing delayed onset muscle soreness. After inducing delayed onset muscle soreness, measurements were taken at the 24th hour, 48th hour, and 72nd hour. Results : The pre-eccentric exercise group and stretching group showed a significant difference from the control group by isometric contract ion power and mechanical pain threshold as a result of measuring delayed onset muscle soreness. Conclusion : From these results, electrical stimulation using presynaptic inhibition mechanism of transcutaneous electrical stimulation (TES) had positive effects for walking ability on inhibition of muscle tone in lower extremity. The motor level stimulation group experienced a more significant effect than the sensory level stimulation group. Therefore, the transcutaneous electrical stimulation (TES) is considered to be effective on walking ability increasing through inhibition of muscle tone in lower extremity for rehabilitation of post stroke hemiplegic patients.

  • Objective: The purpose of this study was to investigate the effects of combined exercise on the change of postural control, functional status in patients with osteoarthritis of the knee. Methods : The subjects were consisted of 24 women patients fifties and sixties with knee osteoarthritis. Each group had a exercise for 30 minutes per day and three times a week during 8 weeks period. Was used to measure muscular function(60, $180^{\circ}/sec$), postural control. functional capacity(15 M walking test, Rising form a chair test, stair climbing and descending test) and the functional state of a joint(WOMAC). Results: This study results in following 1. In case of muscular function have significantly increased in both groups. 2. There was no significant difference in the postural control of the bilateral between two groups. However, the postural control of a isokinetic exercise program group showed a significant difference in the bilateral side(overall, $M{\cdot}L$ stability index). Especially, the change of postural control in the isokinetic plus postural control exercise program group decreased more significantly in the bilateral(overall, $A{\cdot}P$ stability index). 3 It was significantly decreased in climbing and descending the stairs, and rising from the chair, although functional capacity decreased in lam walking in both groups. 4. The functional state of a joint(WOMAC) showed a significant decrease in both groups. Conclusion : In order to improve the functional status and postural control of patients with osteoarthritis of the knee, performing exercise programming of isokinetic plus balance will be more effective than the exercise program composed of only the isokinetic exercise program.

  • The prosthodontic treatment of severely resorbed edentulous patients has been one of the frustrating areas due to extensive loss of tissues. The integrated neuromuscular balance among tongue, lip, and cheek is compromised. The retention, stability, and support are the three major factors to influence the clinical outcome. Fish described a denture as having three surface, with each surface playing an independent and important role in the over all fit, stability, and comfort of the denture. He recommended that the polished surface should be a series of inclines so that pressure from muscular activity will retain dentures. Within the denture space there is an area that has been termed the neutral zone. The neutral zone is that area in the mouth where, during function, the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. According to Jacobson and Krol, neuromuscular control interacts to provide retention and the relationship of polished surface of denture base to the surrounding muscular structure of orofacial capsule facilitates the stability and retention. This neutral zone concept has been demonstrated with various modification by a number of authors. The theory used to develop the denture base contours is based on the belief that the muscle should functionally mold not only the border but the entire polished surface. Lott and Walsh reported the clinical success on complete mandibular dentures with application of neutral zone concept. A number of studies demonstrated that denture stability and retention are more dependent on correct position of the teeth and correct contour of external surfaces of the denture in a severely resorbed alveolar ridge. This article presents a prosthodontic approach to treatment of a edentulous patient using neutral zone technique to improve the retention and stability of the prosthesis.

  • Anoctamin 5 (ANO5)/TMEM16E belongs to a member of the ANO/TMEM16 family member of anion channels. However, it is a matter of debate whether ANO5 functions as a genuine plasma membrane chloride channel. It has been recognized that mutations in the ANO5 gene cause many skeletal muscle diseases such as limb girdle muscular dystrophy type 2L (LGMD2L) and Miyoshi muscular dystrophy type 3 (MMD3) in human. However, the molecular mechanisms of the skeletal myopathies caused by ANO5 defects are poorly understood. To understand the role of ANO5 in skeletal muscle development and function, we silenced the ANO5 gene in C2C12 myoblasts and evaluated whether it impairs myogenesis and myotube function. ANO5 knockdown (ANO5-KD) by shRNA resulted in clustered or aggregated nuclei at the body of myotubes without affecting differentiation or myotube formation. Nuclear positioning defect of ANO5-KD myotubes was accompanied with reduced expression of Kif5b protein, a kinesin-related motor protein that controls nuclear transport during myogenesis. ANO5-KD impaired depolarization-induced $[Ca2^{+}]_i$ transient and reduced sarcoplasmic reticulum (SR) $Ca^{2+}$ storage. ANO5-KD resulted in reduced protein expression of the dihydropyridine receptor (DHPR) and SR $Ca^{2+}-ATPase$ subtype 1. In addition, ANO5-KD compromised co-localization between DHPR and ryanodine receptor subtype 1. It is concluded that ANO5-KD causes nuclear positioning defect by reduction of Kif5b expression, and compromises $Ca^{2+}$ signaling by downregulating the expression of DHPR and SERCA proteins.

  • Recently, The number of hypertension is increasing with westernized diet and lack of exercise. Many researchers are trying to treat and prevent hypertension by exercise therapy. However, not only did most of studies analyze the effect and usefulness of exercise related to lowering hypertension, but also there is no analysis of the difference of fitness with regard to hypertension according to ages. It is assumed to be important research work to be continued to identify, from the public health's point of view, the difference of fitness with regard to hypertension according to ages can be a essential data for treating and preventing hypertension. Thus, this study is to identify the difference of fitness according to hypertension of adult female over 20s and emphasize the importance of fitness level to the hypertension. Also, this study is to devise valuable study by examining the difference of cardiovascular function. Subjects were 8889 of adult female over 20s. Subjects visited promotion of health center at Y Gu public health center and took comprehensive medical test including hypertension test in Seoul in Korea. It was divided into normal, prehypertension, stage I hypertension and stage II hypertension group by JNC7. The evaluation of cardiorespiratory function was by resting heart rate and lung capacity, the evaluation of fitness was by cardiorespiratory endurance, muscular endurance, muscular strength, power, agility, balance, and flexibility, and the difference of fitness was analyzed by ANCOVA revising independent variable of BMI, drinking, and smoking which affects hypertension. At result, there was significant difference between normal and hypertension group according to most ages in two variable of all cardiorespiratory function, seven fitness variable. Through this study, it was defined that hypertension group had lower cardiorespiratory function and fitness than normal group.
