Purpose: This study has proved the intervention effects of the proposed logotherapy-based music imagery (LBMI) program on the self-worth of the personal assistants for the disabled. The program, in the image activities and at the stage of postlude after listening to music, unites logodrama of logotherapy, paradoxical intention and dereflected techniques. The intervention effects of the LBMI program were tested for the 28 personal assistants for the disabled who found themselves without the value and meaning of life and were randomly equally divided into the experimental and control groups. This intervention was carried out for the six different terms, each of which was alloted 60 minutes. To evaluate the intervention effects, the self-worth scale were examined before and after the intervention for both experimental and control group. The result shows that the self-worth improved significantly in the experimental group(p < 0.001), whereas it remained unchanged in the control group(p > 0.459). This finding proves that the proposed LBMI program ameliorates the self-worth of the personal assistants for the disabled.

This study investigates the effectiveness of foreign language learning through diverse treatments in virtual settings, particularly by differentiating virtual environments with three textual enhancement techniques. A 2 × 3 mixed-factorial design was used, treating virtual environments as within-subject factors and textual enhancement techniques as between-subject factors. Participants experienced two videos, each in different virtual learning environments with one of the random textual enhancement techniques. The results showed that the interaction between different virtual environments and textual enhancement techniques had a statistically significant impact on presence among groups. In examining main effects of virtual environments, significant differences were observed in flow and attitude toward pre-post learning. Also, main effects of textual enhancements notably influenced flow, intention to use, learning satisfaction, and learning confidence. This study highlights the potential of Metaverse in foreign language learning, suggesting that learner experiences and effects vary with different virtual environments.

A long-term (26 weeks) feeding experiment was conducted to examine the essentiality and requirement of inositol in diets for olive flounder because no information is available in the species. Five casein-gelatin based semi-purified diets were formulated to contain four different levels of myo-inositol (0, 0+antibiotic, 400, 800, and 1600 mg/kg, designated as M0, M0+, M400, M800, and M1600, respectively). One (M0+) of the control diets contained tetracycline hydrochloride (0.4%, wt/wt) as an antibiotic to inhibit biosynthesis of inositol by micro-organism in intestine of fish. Olive flounder at the early juvenile stage (initial body weight 1.22 g) were randomly distributed into fifteen 35 L tanks (48 fish/tank) and fed with one of the experimental diets (3 replicates per diet). At the end of the feeding trial, the weight gain, feed intake, specific growth rate, and protein efficiency ratio of fish fed diets containing higher levels of myo-inositol (M800 & M1600) were significantly higher than those of fish fed the other diets (P<0.05). Feed conversion ratio, survival, hematocrits, and hemoglobin of fish fed experimental diets were not significantly different among all the fish groups. Whole body compositions of fish were not different except for lipid content. The lipid content was significantly different between M0 and M400 diet groups. These results indicate that juvenile olive flounder requires dietary supplementation of myo-inositol in diets for normal growth and its optimum level seems to be approximately 800 mg myo-inositol/kg diet.

The purpose of current investigation was identified to the effects of swallowing training with surface electromyography biofeedback on swallowing function and dietary level, satisfaction in acute stroke patients with dysphagia. Sixteen acute stroke patients with dysphagia was participated in our study. All stroke paitents were allocated in randomly to experiemental group(n=8) and control group(n=8). Both group received traditional dysphagia therapy during 30min/day, five per week, for four weeks. experimental group was perfomed swallowing training with surface electromyography biofeedback, additionally 30 min/day, and control group received only swallowing training, additionally 30 min/day. Assessments evaluated Functional Dysphagia Scale(FDS) and Penetration-Aspiration Scale(PAS) for measure of swallowing function, and Functional Oral Intake Scale(FOIS) assessed for measure of dietary level. satisfaction assessed by using Visual Analog Satisfaction Scale(VASS). In results, after intervention both group improved significant on swallowing function, and dietary level, compared to before intervention(p<0.05). After intervention, satisfaction of both group was not significant difference(p>0.05). In comparison of change score between two group, experimental group improved significantly than control group in dietary level(p<0.05). Swallowing training with surface electromyography biofeedback may be a effective dysphagia therapy to improve on dietary level in acute stroke patients with dysphagia.

The purpose of this study is to develop music psychotherapy program applying the Inner Family System(IFS) to reduce adult depression and improve self-esteem and to verify its effectiveness. For this, literature search and theoretical basis were prepared, and validity was secured through a demand survey and evaluation by experts. After going through the preliminary program, the final program consisting of 10 sessions was developed after revision and supplementation. To verify the effectiveness of the program, 25 people who met the selection criteria with a score of 20 or higher on the Depression Scale(CES-D) were selected. Of the 25 subjects, 10 subjects in the experimental group, 10 subjects in the control group, and 5 subjects in the preliminary group were randomly assigned and analyzed as final study subjects. The experimental group performed 10 sessions of music psychotherapy applying IFS twice a week for 90 minutes, and the control group did not receive any treatment. As a result of data analysis, first, it was confirmed that there was a difference between the experimental group and the control group in the change patterns according to the measurement period of overall depression and the sub-factors, depressive emotion, interpersonal emotion, and physical depression score. Second, the effects were statistically significant on overall self-esteem and sub-factors such as self-deprecation, relationship with others, leadership and popularity, assertion and anxiety. Third, it was confirmed that the pattern of change according to the measurement period of the IFS score differed between the experimental and control groups.

The purpose of this study was to compare immediate differences in fatigue and motor performance during instrumental playing in patients with chronic stroke depending on whether singing task was concurrently presented. A total of 12 patients with chronic stroke were recruited from community and daycare centers for older adults in Seoul. Six subjects were randomly assigned to the experimental group and six to the comparison group. The experimental group was asked to sing while playing the electronic drum, and the comparison group only played the drum. The results of this study showed that statistically significant differences in perceived fatigue and exertion were found between the two groups, while no significant group differences were found in level of engagement in playing or force of tapping during drum playing. This study supports the inclusion of a singing task in instrument playing rehabilitation to effectively decrease perceived fatigue and level of intensity of exercises, although this may not lead to immediate changes in motor function or level of target exercises. The results indicate that singing while instrument playing may help stroke patients shift their attention from the executed motor movements to singing and alleviate the attentional and emotional load from intense movements. This study presents implications for how to select and pattern target movements in music therapy intervention for better motor outcomes.

This study was to determine the effect of 12-week balance training with visual feedback on balance and walking functions in patients with post-stroke hemiparesis. Twenty individuals with chronic stroke volunteered to participate in this study. They were randomly allocated to either experimental group (EG) or control group (CG), with 10 subjects in each group. Subjects from the group 1 underwent 15-min balance training with visual feedback and 15-min routine-scheduled physical therapy, and subjects from the group 2 performed 30-min routine-scheduled physical therapy only, which comprised mat exercise, strengthening, postural correction, and functional practice. Assessment tools were made with the Functional Reach Test (FRT), Timed Up and Go Test (TUGT), and 6 Min Walk Test (6MWT). In within-group comparison, the EG showed significant differences in all parameters (p<0.05), while significant differences were not found for the CG (p>0.05). In between-group comparison, the change values of the FRT and 6MWT appeared to be significantly greater for the EG than those of the CG (p<0.05). These findings suggest that balance training with visual feedback may be favorably used to improve balance and walking functions in patients with chronic post-stroke hemiparesis. Further studies with larger sample and long-term follow-up period need to generalize the results of this study.

The purpose of this study is to compare the efficiency of bacteria removal of three different types of hand washing methods. This study performed a convenient sampling of 30 volunteers in cross-over design. The study divided the 30 volunteers into three random groups. The three groups were asked to use antiseptic soap, alcohol-based hand disinfectant, and disposable wet wipes respectively. The result of the study showed that mean log reduction values after each had washing method were $-0.45({\pm}0.69)$ with antiseptic soap and water, $-1.19({\pm}0.52)$ with alcohol-based hand disinfectant and $-0.75({\pm}0.58)$ with disposable wet wipes. The difference was statistically significant when using alcohol-based hand disinfectant compared to the other two methods (p=0.000). According to this study, alcohol-based hand disinfectant was the most effective product based on bacteria removal for hand washing. Advantages of using alcohol-based hand disinfectant are that it is cost-effective and easy to buy, also eco-friendly. Therefore, to prevent infectious disease, providing alcohol-based hand disinfectant to every corner of the community will be very helpful.

Bertrand's Paradox is known as a paradox because it produces different solutions when we apply different method. This essay analyzed diverse problem solving methods which result from no clear presenting of 'random chord'. The essay also tried to discover the difference between the mathematical calculation of three problem solvings and physical experiment in the real world. In the process for this, whether geometric statistic teaching related to measurement and integral calculus which is the basic concept of integral geometry is appropriate factor in current education curriculum based on Laplace's classical perspective was prudently discussed with its status.

Adenosine deaminase gene from Nocardioides sp. J-326TK was cloned by polymerase chain reaction using primers (PI, PII and PIII) constructed from the highly conserved amino acid sequences among Escherichia coli, mouse and human. A PCR product of about 800bp, as expected from the sequence of E. coli adenosine deaminase gene, was obtained from Nocardioides sp. J-326TK chromosomal DNA double-digested with EcoRI and Pst I. DNA sequencing of the PCR product after cloning into pT7Blue T-vector shows 99.5% and 98.9% homologies in nucleotide and amino acid sequences, respectively, with the E. coli adenosine deaminase whereas 59.5% and 46.8% homologies with the human adenosine deaminase, indicating the evolutionarily relationship of these organisms.
