The purpose of this study was to explore the relationship between students’ cognitive engagement with written corrective feedback (WCF) and their revision behavior. Based on the assumption that different levels of cognitive involvement are linked to learners’ use of the feedback, we investigated how different post-feedback activities (i.e., reading, copying, and explaining the feedback) would affect second language writers’ behavioral engagement with WCF during the revision phase. Ninety-eight students were divided into three experimental groups and one control group. Experimental groups performed one of the three post-feedback activities before revising their original writing. The participants’ revision behavior was examined by their uptake of WCF. Additionally, the change in writing quality between the first and the revised drafts was investigated. Results showed that activities that promote deeper cognitive processing generally led to higher uptake of WCF in revision. The effects of post-feedback activities, however, varied for error types. All the post-feedback activities were effective in improving the quality of writing.

The amount of radioactive waste generated during decommissioning directly affects the disposal cost of waste. Most of the radioactive waste generated is a concrete waste. Therefore reducing the amount of concrete waste can ensure the economic feasibility of the decommissioning project. The activated concrete in a concrete waste can reduce waste only by physical cutting. Therefore it is most important to accurately identify and categorize radionuclides, radioactivity levels, and radioactivity distribution. In the case of radioactive concrete, radiological characteristics are generally evaluated by laboratory analysis after sampling. However it is difficult to apply to all facilities (accelerator & NPP, etc.) because it is a destructive method. Therefore it is necessary to secure verified in-situ measurement technology that can be applied to operational monitoring or decommissioning plans. In this study, the applicability of cyclotron facilities was evaluated based on the evaluation algorithm derived from the Peak to Compton (PTC) method of in-situ measurement technology. And the reliability of the PTC method was verified through qualitative analysis and quantitative analysis. In the case of qualitative analysis, the analysis results of KAERI which has core technology are compared. To this end SAEAN and KAERI conducted field application tests on the front concrete shielding wall of the cyclotron facility at the same time. After removing the background spectrum from the measured spectrum the PTC method was applied to calculate the Q-value for the counting rate in the peak area per counting rate in the Compton continuum area was calculated. As a result the Q-values of SAE-AN and KAERI were 0.52 and 0.24 respectively, and the result of deriving activation distribution(β) by substituting this for the β-Q correlation equation was found that 14.78 and 12.94. As a result of evaluating the activation by the thickness of the shielding wall it was found that 89.1% (SAE-AN) and 91.9% (KAERI) of the total radioactivity were exist at a depth of 5 cm. And it was found that 97.7% and 99.05% of the total radioactivity exists at a depth of 10 cm. The relative error between SAE-AN and KAERI is 1.35%, indicating that the analysis results of the two institutions are highly consistent. A core drill was performed on the concrete shielding wall in the cyclotron facility for the technical verification of the quantitative analysis method. A core sample (6 cm in diameter, 10 cm in depth) was cut to a depth of 2 cm and analyzed in the laboratory. The activation distribution(β) was calculated based on the radioactivity level of each depth sample, and it was found to be 16.99. The relative error between the quantitative analysis and the on-site measurement results was 14.95% confirming that the accuracy is relatively high.

Background: The gastrocnemius (GCM) is one of the lower extremity muscles that tend to tighten easily. GCM tightness results in limited ankle dorsi-flexion (DF), especially when the knee joint is fully extended. Joint flexibility is determined by the morphological and physiological characteristics of joints, muscles, tendons, and ligaments. Impaired joint flexibility can be attributed to increased susceptibility to muscle injury. High-frequency diathermy is clinically used to reduce pain and muscle tightness and to improve limited range of motion. Objects: This study aimed to investigate the immediate effects of high-frequency therapy in subjects with GCM tightness. Methods: The study was designed as a one-group before–after trial. The subjects included 28 volunteers with GCM tightness (an active ankle DF angle of less than 12°) without any known neurological and musculoskeletal pathologies in the ankle and calf areas. WINBACK Transfer Electrode Capacitive and Resistive Therapy equipment was used to apply high-frequency therapy to the subjects’ GCMs for 10–15 minutes. The pennation angle and the fascicle length of the GCM were measured using ultrasonography. The flexibility of the ankle joint, peak torque to the passive ankle DF (Biodex), and soft tissue stiffness (MyotonPRO) were also measured. Results: The pennation angle was significantly decreased following the treatment; however, no significant difference in the fascicle length was found (p < 0.05). The flexibility was significantly increased and both the passive peak torque to passive ankle DF and the soft tissue stiffness significantly decreased (p < 0.05). Conclusion: High-frequency therapy is immediately effective for improving the muscle’s architectural properties and functional factors in subjects with GCM tightness. Further longitudinal clinical studies are required to investigate the long-term effects of high-frequency therapy on subjects with GCM tightness from various causes.

Background: Stress urinary incontinence (SUI) is an involuntary leakage of urine from the urethra when intra-abdominal pressure increases, such as from sneezing, coughing, or physical exertion. It is caused by insufficient strength of the pelvic floor and sphincter muscles, resulting from vaginal delivery, obesity, hard physical work, or aging. The pelvic floor electrical stimulator is a conservative treatment generally used to relieve the symptoms of urinary incontinence. it recommended to applied before surgery is performed. Objects: The purpose of this study was to determine if the transcutaneous electrical stimulation (TCES) would be effective for the physiological symptoms and psychological satisfaction of women with SUI for an 8-weeks intervention. Methods: Easy-K is a specially designed user-friendly TCES. Five female who were diagnosed with SUI by a gynecologist but who did not require surgical intervention were included in this study. Intervention was implemented over an 8-week period. Outcome measures included vaginal ultrasonography, Levator ani muscle (LAM) contraction strength, incontinence quality of life (I-QOL), and female sexual function index (FSFI) questionnaires. Results: The bladder neck position significantly decreased across assessment time. Funneling index and urethral width significantly decreased after 8 weeks of intervention (p<.05). The bladder necksymphyseal distance and posterior rhabdosphincter thickness statistically increased and the anterior rhabdosphincter thickness showed a tendency to increase. All participants demonstrated a significant increase in the LAM contraction score across three assessment times (p<.05). Although the total score of the I-QOL did not show significant improvement, it steadily increased and among I-QOL subscales, only the “avoidance” subscale showed statistical improvements (p<.05). The total score of the FSFI statistically improved and the “desire” score significantly changed (p<.05). Conclusion: The TCES is recommended for women who want to apply conservative treatments before surgery and who have suffered from SUI in aspects of sexual function and quality of life.

This study investigates the use of the English definite article by Korean middle school students and examines the effects of explicit instruction on the article. Two hundred and seventy-two Korean middle school students were instructed on the core meaning of the definite article, identifiability, through a processing instruction method and were tested on their uses of the target form before and after instruction. The pretest results show that the various non-generic uses of the English definite article pose different levels of difficulty for Korean middle school learners of English. The comparison between the pretest and posttest results confirm the positive effect of teaching the core meaning of the definite article. All in all, the study shows that the non-generic use of the English definite article is teachable through the introduction of its core meaning in the EFL classroom. It provides substantial empirical evidence for the facilitative role of focus on form instruction in the acquisition of definite article in an EFL context.

This study investigated the effects of two types of corrective feedback (CF), recasts and metalinguistic feedback (implicit vs. explicit CF), on the development of implicit and explicit knowledge of English articles. It also examined the relationship between learners’ language aptitude, in particular language analytic ability, and their knowledge development through different types of CF. Six intact intermediate communication English classes (a total of 104 students and two English-speaking teachers) at a university participated in the present study. In CF groups, learners received recasts or metalinguistic feedback (MF) to the errors of the English articles during communicative activities, while no CF was given to the control group. The study employed a pretest-posttest-delayed posttest design, and four different tests were used to measure learner implicit and explicit knowledge. The study found both recasts and MF effective in the development of implicit knowledge and selective effects of recasts on the improvement of explicit knowledge. This suggests that both implicit and explicit CF bring about the development of implicit and explicit knowledge. In addition, language analytic ability was found to be closely related to learners’ gains through both CF and development of explicit and implicit knowledge of English articles.

Background: Scapular downward rotation syndrome (SDRS) is a common scapular alignment impairment that causes insufficient upward rotation and muscle imbalance, shortened levator scapulae (LS) and rhomboid, and lengthened serratus anterior (SA) and trapezius. A modified shrug exercise (MSE), performing a shrug exercise with the shoulders at 150° abduction, is known as an effective exercise to increase scapular stabilizer muscle activation. Previous studies revealed that scapular exercise are more effective when combined with trunk stabilization exercises in decreasing scapular winging and increasing scapular stabilizer muscle activation. Objects: The purpose of our study was to clarify the effect of MSE with or without trunk stabilization exercises in subjects with SDRS. Methods: Eighteen volunteer subjects (male=10, female=8) with SDRS were recruited for this experiment. All subjects performed MSE under 3 different conditions: (1) MSE, (2) MSE with an abdominal draw-in maneuver (ADIM), and (3) MSE with an abdominal expansion maneuver (AEM). The muscle thickness of the lower trapezius (LT) and the SA were measured using an ultrasonography in each condition. Electromyography (EMG) data were collected from the LT, LS, SA, and upper trapezius (UT) muscle activities. Data were statistically analysed using one-way repeated analysis of variance at a significance level of .05. Results: The muscle thickness of the LT and the SA were the significant different in the MSE, MSE with ADIM (MSE+ADIM) and MSE with AEM (MSE+AEM) conditions (p<.05) In both LT and SA, the order of thick muscle thickness was MSE+AEM, MSE+ADIM, and MSE alone. No significant differences were found in the EMG activities of the SA, UT, LS, and LT in all condition. Conclusion: In conclusion, MSE is more beneficial to people with SDRS when combined with trunk stabilization exercises by increased thickness of scapular stabilizer muscles.
