PURPOSE: The purpose of this study was to identify the effects of physical therapy plus Kinesio taping (KT) on muscle tone and stiffness in patients with shoulder pain. METHODS: This study included 22 participants who were divided into the experimental group (n=11) who underwent a routine physical therapy with KT and the control group (n=11) who received the same physical therapy only. The physical therapy consisted of heat application and electrical stimulation. Heat was applied for 10 minutes and electrical stimulation was conducted for 20 minutes. Intervention was provided over a 1-week period, and frequency for muscle tone and stiffness was measured to determine changes in shoulder muscle status. The muscles were supraspinatus and deltoid. Measurements were taken before, after 1day, 3day and after 1 week to identify time-dependent effects of intervention. RESULTS: The effects of the intervention were significant in both groups, and effects were greater in the experimental group. Changes in muscle tone and stiffness were statistically significant in both groups and at varying time points (p<.05). CONCLUSION: Based on the improved muscle performance found in this study, KT is considered an effective intervention strategy for patients with shoulder pain when it is combined with conventional physical therapy.

Com and rice starches were physically modified by planetary mill. While native starches showed high peak viscosities (1,001 and 563 cp), it decreased largely (42 and 20 cp for rice and com starch, respectively) after 2 hr of physical modification. When two starches were co-ground, peak viscosities decreased more largely than single ground one only in 30 min, indicating the pasting properties could be easily changed by co-grinding. Especially, the higher the amount of com starch, the viscosity decreased more largely, which means that paste stability could be controlled also by changing the ratio of com and rice starch. Mean particle size increased with physical modification time since particles became spread because of shear force. There were also changes in surface morphology after physical modification. Fluid property, such as mean time to avalanche (MTA), was improved (from $6.16{\pm}0.47$ and $8.37{\pm}1.23\;sec$ to $5.47{\pm}0.78$ and $5.26{\pm}1.37\;sec$ for rice and com starch, respectively) by physical modification. Pasting property, such as swelling power, was also improved by physical modification. These mean that native starches can be applied to both conventional powder and new paste-food industry more efficiently by physical modification.

This research takes granite stone based floor finishing exposed to concentrated downpouring and observes the material's physical changes, adhesiveness, compressive strength under wet conditions. The results of the experiments shows that elution of sulfide mineral can occur when granite stones are exposed to downpour, but short term exposure shows little physical changes to the material. This indicates that if post maintenance is properly enacted, long term usage of granite stone materials is also possible.

Anatomy: Advanced knowledges of cellular and molecular biology led to the development of therapies of rheumatoid arthritis(RA). Rheumatoid arthritis (RA) is a chronic, recurrent, systemic inflammatory disease and results in major deformity or dysfunction of joints. Etiology: Rheumatoid arthritis is now concevied as autoimmune disease. There have been many trials to define the immunological changes in rheumatoid arthritis. But now pathogenesis and significance of immunoglobulin complement and rheumatoid factor are not full accepted. Syndrome: Joints are characteristically involved with early inflammatory changes in the synovial membrane, peripheral portions of the articular cartilage, and lation tissue(pannus) forms, covers, and erodes the articular cartilage, bone and ligaments within the jiont capsule. Inflammatory changes also occur in tendon sheaths(tenosynovitis), and if subjected to a lot of friction, the tendons may fray or rupture. Extra-articular pathological changes sometimes occur, these include rheumatoid nodules, atrophy and fibrosis of muscles, and mild cardiac changes. Treatment: Tumor necrosis factor(TNF) inhibitor for the treatment of rheumatoid arthritis(RA) induces not only significant improvement of symptoms and signs of RA but also substantial inhibition of progressive joint damage.

To correlate the conformational changes of DNA (Calf Thymus) with entrapment of DNA into liposomes, the effect of ions ($Na^+$, $Mg^{++}$on the entrapment of calf thymus DNA into liposomes was investigated. The effect of divalent ion ($Mg^{++}$ on the structural changes of DNA indicated by decrease of observed ellipticity at 274 nm and nonspecific binding of DNA to lipid bilayers was greater than monovalent ion ($\Na^+$). But the efficiency of DNA encapsulated was not altered. These results show that entrapment of DNA into liposomes is not due to nonspecific binding and structural changes because of electrostatic forces but to mechanical capture of DNA by the internal aqueous space of liposomes although divalent ion contributes large structural changes and more nonspecific association of DNA with liposomes due to strong charges.

Purpose: This study attempted to provide the basic data for the institutional improvement of the clinical practice of physical therapy department students. Methods: Research for this study included 390 participants used for the analysis of the present study. The statistical analysis was of the characteristics and satisfaction of the clinical practices of subjects, the reasons for major employment preferences before and after clinical practices, and the preferred institution and field of major employment before and after clinical practice. Results: The general characteristics of students of the physical therapy department include females in their third year of college at age 20~24 years-old. As well, no religion, usual satisfaction with major, and motivation of choosing a physical therapy employment rate were the most common. A residency type in the form where one would cook one's own food and a clinical practice with a general hospital grade were seen most often. Regarding preference of major employment before and after clinical practice, the preference of major employment was 88%, which increased by 5.2% after clinical practice from 82.8% before clinical practice. The preference for no major employment due to lack of interest and no aptitude increased 43.5% from 23.9% after clinical practice. Conclusion: The number of apprentices will increase despite practice institutions being limited; for practice of environment, content, etc., relatively changes are slow, and progress rapidly medical technology. It is a society in which expertise is required; in the present study, there is a value in providing the clinical data missing in physical therapy.

Objective: This study was carried out to compare changes in pain, swelling and range of motion (ROM) between the two groups according to physical therapy intervention. Design: Randomized controlled trial. Methods: There were a total of 20 elderly subjects ages 65-75 years old who have been admitted to the hospital for a total knee arthroplasty. After surgery, the experimental group (n=10) carried out quadriceps femoris muscle strengthening exercise, hamstring stretching exercises and gastrocnemius stretching exercise with a physical therapist for 30 minutes and additionally, received ice pack therapy for 20 minutes once a day. The control group (n=10) carried out continuous passive motion for 30 minutes and received ice pack therapy for 20 minutes once a day. The experimental group and control group carried out each intervention program for 2 weeks 3 times a week. The Visual Analogue Scale was used to assess pain, tape measurements were taken to assess swelling, and a steel goniometer was used to assess knee joint ROM. Results: As a result, the experimental group showed a statistically significant decrease in the pain and swelling, and a significant increase in knee flexion ROM after the intervention, compared to the control group (p<0.05). There was a significant improvement in pain, edema, and knee flexion and extension ROM in all subjects after intervention (p<0.05). Conclusions: According the results of this study, exercise in the experimental group is effect on the pain, swelling and ROM for total knee arthroplasty.

Physical and chemical changes in a polished wafer and in $2.5{\mu}m$ & $4{\mu}m$ epitaxially grown Si layer wafers (Epilayer wafer) after surface treatment were investigated. We characterized the influence of surface treatment on wafer properties such as surface roughness and the chemical composition and bonds. After each surface treatment, the physical change of the wafer surface was evaluated by atomic force microscopy to confirm the surface morphology and roughness. In addition, chemical changes in the wafer surface were studied by X-ray photoemission spectroscopy measurement. Changes in the chemical composition were confirmed before and after the surface treatment. By combined analysis of the physical and chemical changes, we found that diluted hydrofluoric acid treatment is more effective than buffered oxide etching for $SiO_2$ removal in both polished and Epi-Layer wafers; however, the etch rate and the surface roughness in the given treatment are different among the polished $2.5{\mu}m$ and $4{\mu}m$ Epi-layer wafers in spite of the identical bulk structural properties of these wafers. This study therefore suggests that independent surface treatment optimization is required for each wafer type, $2.5{\mu}m$ and $4{\mu}m$, due to the meaningful differences in the initial surface chemical and physical properties.

PURPOSE: This study was conducted to investigate the effects of type of exercise on neck disability, pain, and postural changes in subjects with forward head posture. METHODS: Two independent researchers conducted a search using KISS, RISS, DBpia (domestic), PubMed, OVID, and Science Direct (overseas) databases. We selected randomized controlled clinical trials by searching using the terms "forward head posture", "exercise therapy", and "therapeutic exercise". Studies published from 2007 to December 2017 were included. PEDro Scale was used to evaluate the quality of the selected studies, and meta-analysis was conducted using the CMA program. This review was registered at PROSPERO (CRD42018068633). RESULTS: Of the total 13768 studies searched, 17 were selected. Positive effects on neck disability were achieved with the base and biomechanical elements (ES=1.63, 95% confidence interval [CI] .49 to 2.75) as well as base, modulator, and biomechanical elements (ES=1.50, 95% [CI] .69 to 2.30). Neck pain improved with the base, modulator, and biomechanical elements (ES=1.96, 95% [CI] 1.08 to 2.82), while postural changes improved with biomechanical elements (ES=1.45, 95% [CI] .64 to 2.25). Additionally, type of exercise had a positive effect. CONCLUSION: The most effective exercises for neck disability are of the base and biomechanical elements, while the most effective types for neck pain are of the base, modulator, and biomechanical elements and the most effective exercise for posture is of biomechanical elements. Combined exercises targeting biomechanical elements were effective at treating disability, pain, and postural changes.
