This study was investigated the effects on functional recovery of eccentric exercise-induced muscle damage by phonophoresis transdermal permeation of piroxicam gel and observed the change of amplitude at muscle action potential. Through eccentric exercise-induced muscle damage, performed healthy men and women take eccentric resistance exercise and measured action, potentials. The subjects were divided into three groups of four men each 24 hour, 48 hour, 72 hour. The results of this were as follows: 1. Change of maximal action potential at maximal voluntary contraction : The phonophoresis group was increase more than control group and gel group. 2. Change of average action potential at maximal voluntary contraction : The gel group was increase more than control group and phonophoresis group. 3. Change of maximal action potential at pain subthreshold voluntary contraction : The phonophoresis group was increase more significantly than control group and gel group. 4. Change of average action potential at pain subthreshold voluntary contraction : The phonophoresis group was increase more significantly than control group and gel group. In conclusion, the change of muscle action potential amplitude by eccentric exercise-induced muscle damage showed that the phonophoresis by pulsed ultrasound of piroxicam gel was improved the recovery of muscle function.

Effects of sosihotangganogyong on the activity of serum transferase and hepatic lipid peroxide in mice with $CCl_4$ solution were determined. The activity of ALT showed a high value in the mice with $CCl_4$, however in the mice with sosihotang and sosihotangganogyong, these values showed a tendency to rapid recovery compared with those of the mice with $CCl_4$ only and the activity of ALT in the group of sosihotang and sosihotangganogyong showed a low values compared with $CCl_4$ only group on the 21 days after treatment. On the 21 days after treatment, the activities of glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and lactic dehydrogenase (LDH) in the mice with sosihotang and sosihotangganogyog were similar to those of control group, however these values of $CCl_4$ only group showed a high values compared with those of other groups. The value of hepatic lipid peroxide in the mice with sosihotang and sosihotangganogyong showed a tendency to rapid decrease and recovery compared with those of $CCl_4$ only group and on the 21 days after treatment, this value showed a similar to those of control group. The activity of serum transferase and the value of hepatic lipid peroxide in the mice with sosihotngganogyong showed a tendency to decrease compared with those of sosihotang group, however these values showed a no significantly deference. Results from this study indicated that the sosihotagganogyong can effectively improve the recovery of liver function in mice with $CCl_4$.

The purpose of the present study was to examine the functional recovery of the crushed sciatic nerve of rats after low-power laser irradiation applied to the corresponding segments of the spinal cord. After a crushed injury on the left sciatic nerve in rats. low-power laser irradiation was applied transcutaneously to corresponding segments of the spinal cord immediately after suture the wound by using 2000 mW, 2000Hz, 830 nm CaAIAs(Gallium-aluminum-arsenide) semiconductor diode laser. The laser treatment was performed with 10 minutes daily for 4 successive weeks. Functional recovery was evaluated per weekly following injury by sciatic function index(SFI),using data obtained by walking track analysis. For four weeks after crush injury, experimental group had significantly greater functional improvement than control group(${\alpha}$=0.05). In a experimental group, SFI was significantly increased for three weeks, but control group not increased for two weeks. This study suggests that low-power laser irradiation applied directly to the spinal cord can improve functional recovery of the crushed sciatic nerve in rats.

Aim of this study is to investigate the perception and purchasing status of functional beverages for adults in the Chungnam area. In this case, the reasons to buy the functional beverages for men were 'recovery of fatigue (43.1%)', 'quenching thirst (21.6%)', 'health promotion (19.6%)', 'supply of nutrition (15%)', and 'a loss in weight (7%)'. Otherwise the reasons to buy the functional beverage for women showed to be 'recovery of fatigue (28.6%)', 'health promotion (26.4%)', 'quenching thirst (22.1%)', 'supply of nutrition (12.9%)', and 'a loss in weight (10%)', which were significant different between the men and women subjects. The place to buy functional beverages was for singles (46.5%) a store and for married person a supermarket. The purchase of functional beverages was affected by as follows; manufactured date > original granule > nutrition sign > country > price > taste > brand > scent > color and the women are affected more than men. For functional beverages, the men preferred to buy an energy drink and vitamin drink more than the women. After the intake of functional beverages, the men and women recognized the effect on 'recovery of fatigue' and 'a loss of weight/release of a feeling of hunger/improvement of constipation', respectively. Considering the results of the study, it is necessary to clarify the function of functional beverages so that consumers can choose and take the correct functional beverage by themselves. In addition, the nutritional education should be conducted for the intake allowance for the compositions and excessive or inadequate intake of functional beverages.

The proliferation of the Internet of Things (IoT) technologies and applications, especially the rapid rise in the use of mobile devices, from individuals to organizations, has led to the fundamental role of secure wireless networks in all aspects of services that presented with many opportunities and challenges. To ensure the CIA (confidentiality, integrity and accessibility) security model of the networks security and high efficiency of performance results in various resource-constrained applications and environments of the IoT platform, DDO-(data-driven operation) based constructions have been introduced as a primitive design that meet the demand of high speed encryption systems. Among of them, the TMN-family ciphers which were proposed by Tuan P.M., Do Thi B., etc., in 2016, are entirely suitable approaches for various communication applications of wireless mobile networks (WMNs) and advanced wireless sensor networks (WSNs) with high flexibility, applicability and mobility shown in two different algorithm selections, TMN64 and TMN128. The two ciphers provide strong security against known cryptanalysis, such as linear attacks and differential attacks. In this study, we demonstrate new probability results on the security of the two TMN construction versions - TMN64 and TMN128, by proposing efficient related-key recovery attacks. The high probability characteristics (DCs) are constructed under the related-key differential properties on a full number of function rounds of TMN64 and TMN128, as 10-rounds and 12-rounds, respectively. Hence, the amplified boomerang attacks can be applied to break these two ciphers with appropriate complexity of data and time consumptions. The work is expected to be extended and improved with the latest BCT technique for better cryptanalytic results in further research.

The terrible triad of the shoulder, a combination of anterior shoulder dislocation, massive rotator cuff tear and neurologic injury, is rare. We experienced 4 patients with this condition who were treated with a rotator cuff repair. The mean age was 65 years. Follow-up averaged 27 months. All patients had a history of redislocation after initial traumatic shoulder dislocation and were evaluated with electromyography and magnetic resonance imaging. At the operation, massive rotator cuff tear and hypertrophy of the long head of the biceps were found in all patients. Clinically, 3 patients achieved recovery of their nerve injury by 3 months postoperatively and the final results were fair. In one patient, there was no recovery of deltoid function and this case was rated as a failure. For this injury pattern, the prognosis appears to be dependent on eventual nerve recovery when the rotator cuff has been repaired early.

Objectives This study was conducted to verify the effectiveness of east-west integrative rehabilitation therapy on activity of daily living and cognitive functional recovery in stroke patients by comparing with integrative rehabilitation therapy group and conventional rehabilitation therapy group in a single institution. Methods The medical records of 106 stroke patients hospitalized in Department of Rehabilitation Medicine, Dongguk University Bundang Oriental Hospital from January 1, 2017 to February 28, 2019 were reviewed. After screening and dividing it into conventional rehabilitation (CR) group and integrative rehabilitation (IR) group, Korean version of Modified Barthel Index (K-MBI), functional independence measure (FIM), clinical dementia rating-sum of boxes (CDR-SB) were statistically analyzed. Results IR group showed significant improvement in K-MBI, FIM, and CDR-SB after treatment (p<0.001) and there was a statistically significant difference in K-MBI and CDR-SB score changes than CR group (p<0.05). And chronic patient of IR group showed significant improvement in K-MBI, FIM, and CDR-SB after treatment (p<0.01) and there was a statistically significant difference in CDR-SB score changes than CR group (p<0.05). In particular, the earlier the treatment initiation time, the more the improvement in function and when the treatment started within 2 years from the onset and patients took acupuncture and pulsed electromagnetic therapy, all scales significantly improved (p<0.001). Conclusions IR showed more improvement on activities of daily life and cognitive functional recovery than CR in this study.

ELF, an abbreviation for Executable and Linkable Format, is the basic file format for shared libraries and executable files used in the Linux system, whereas 'Linker' copies the symbol information of static shared libraries into the symbol table in the target file generated by way of static linking. At this time, the symbol table keeps various pieces of debugging-related information including function names provided by the shared libraries, and it can be deleted to avoid debugging for security reasons by utilizing the fact that it does not directly affect the program execution. This paper proposes a method for restoring the symbol information of static shared libraries from the ELF object file in which the symbol table is deleted, and confirms that the symbol information is restored by conducting practical experiments.

Background: This study was undertaken to compare the outcome of supervised and home exercises with respect to range of motion (ROM), pain, and Single Assessment Numeric Evaluation (SANE). We further correlated the ROM recovery and pain reduction as well. Methods: The study included 49 patients who underwent arthroscopic rotator cuff repair. Rehabilitation was initiated after 4 weeks of immobilization. A total of 29 patients performed supervised exercise 3 times a week. Standardized education and brochures for review were provided to the remaining 20 patients who insisted on home rehabilitation. Statistical analysis was performed for comparing pain Numerical Rating Scale (NRS), SANE, and ROM. In addition, we also evaluated the correlation between pain and ROM. Results: Comparison of the two groups revealed no significant differences in forward flexion, internal rotation, abduction, and pain NRS. However, SANE at the 9th week (63.8 vs. 55.0, p=0.038) and improvement of external rotation from the 5th to the 9th week (17.6 vs. 9.3, p=0.018) were significantly higher in the supervised exercise group as compared to the home exercise group. Correlation of pain NRS with forward flexion, external rotation, internal rotation and abduction were statistically not significant (correlation coefficient=0.032 [p=0.828], -0.255 [p=0.077], 0.068 [p=0.642], and -0.188 [p=0.196], respectively). Conclusions: The supervised rehabilitation after arthroscopic rotator cuff repair showed better improvement in external rotation and higher SANE score after 4 weeks of rehabilitation exercise. However, no statistically significant correlation was observed between the recovery of ROM and short-term pain relief.

This study was performed to evaluate the effects of low-intensity ultrasound application to the peripheral nerve injury animal model on enhancement of nerve regeneration and functional recovery. Using aseptic microsurgical techniques, the sciatic nerve of adult male Sprague-Dawley rats was crushed at the outside of right mid-thigh for 30 seconds with fine forceps. Beginning just after surgery, various continuous-wave ultrasound treatments with intensities of 0.2 W/$cm^2$, 0.5 W /$cm^2$ and 1.0 W /$cm^2$ operated at 1 MHz or sham treatment were applied to the opposite inside of the crush site for 1 minute every other day with a transducer moving speed of 2cm/sec. For evaluation of the progress of sciatic nerve regeneration, c-Fos expression in the lumbar spinal cord (L4-5) dorsal horn was investigated. c-fos expression was markedly increased at 1hour after sciatic nerve crush injury, then gradually decreased thereafter. The c-fos expressions were significantly decreased (p<0.05) in all the experimental groups in comparison with the control group until 3days post-crush, and the degrees of decrease were higher in 0.5 W/$cm^2$ and 1 W/$cm^2$ intensity ultrasound application groups. It is suggested that low-intensity ultrasound application to an animal model of sciatic crush injury may suppress pain transmission and promote nerve regeneration, and which may result in delayed progress of muscle atrophy and accelerated progress of muscle recovery and eventually may result in accelerated and improved foot function recovery.
