  • Purpose: Sarcopenia is defined as a decrease in muscle mass, strength, and function with age that affects overall body function. We aimed to investigate the effect of combined training on body composition, balance, and muscle function in sarcopenia elderly. Research design, data, and methodology: Twenty-eight sarcopenia elderly (age 74.9±4.5 years) were randomly assigned to an exercise, EG (n=14), or a control, CG (n=14), group. The EG performed an intervention consisting of combined exercise training (60-75 min) for a total of 12 weeks, three times a week. The CG maintained their usual daily lifestyle during the intervention period. We measured body weight, body mass index (BMI), % body fat, free fat mass, balance ability, peak torque in shoulder, knee, and lumbar joints normalized for bodyweight in one second. Results: The EG showed improved body composition (i.e., BMI, fat-free body mass, fat mass; all p < 0.031, η2 > 0.179), balance (i.e., right and left of static and dynamic balance and fast 10 m walk; all p < 0.049, η2 > 0.152), and muscular function (i.e., 90°/sec and 180°/sec peak power per kg bodyweight, 90°/sec average power per kg bodyweight, 180°/sec total work, and 180°/sec endurance ratio; all p < 0.045, η2 > 0.158). Conclusions: Combined exercise training improves muscle mass and strength, body composition, balance, and muscle function in sarcopenia elderly.

  • The study aimed to estimate the importance of job tasks, job training requirement and work satisfaction felt by dental hygienists to help dental hygienists work efficiently and effectively. A total of 142 dental hygienists working in dental hospitals located in J participated in the study. A SPSS 10.10 for Windows was used for statistical analysis. The statistical significance was defined as ${\alpha}$=.05. The results of the study are summarized as follows: 1. The mean score for the importance of job tasks was 4.09. The respondents considered dental clinic management and assistance to dentists the most important among their job descriptions showing the mean score of 4.44. The need for job training was 4.15 in average. The respondents wanted to have training on how to make a dental health insurance claim to receive payment other than any training with the mean score of 4.42. The work satisfaction of the respondents was 3.65 in average. The respondents were most satisfied with their work in dental assistance. 2. By the category of job tasks, the levels of importance of job tasks, job training requirement and work satisfaction were higher in plague removal with an ultrasonic scaler related to clinical oral prophylaxis, pit and fissure sealants related to preventive dental treatment and instruction in the correct usage of toothbrush related to public dental health education 3. In dealing with dental radiation machines, the radiation protection was considered the most important. While the training for periapical radiography was most needed, the respondents were satisfied with working in the same area. The levels of job importance, training requirement and work satisfaction were high in preventive dental care in the community performed in relation to the public dental health care. 4. In the dental health insurance claim category, the levels of importance of job task, training requirement and work satisfaction were higher in insurance claiming. The levels of job importance and training requirement were high in dental clinic management and assistance to dentists performed for preventive dental treatment. The work satisfaction was higher in maintaining medical chart records. The levels of job importance, training requirement and work satisfaction were higher in dental assistance in relation to dental protection. 5. There was significant relationship between the level of importance and work experience. Those with a longer period of work experience had higher levels of job importance in dental health insurance claim, dental clinic management and assistance to dentists and the overall task(pE0.05). 6. A significant relationship was observed between the need for job training in dental cleaning and preventive dental treatment and work experience. Those with more than 8 years of work experience demonstrated that job training is most needed(pE0.05). 7. The work satisfaction level was higher in the group with more than 8 years of work experience, compared with those in other work experience periods(pE0.05). 8. A positive correlation was seen between the level of importance and the need for job training among three variables.

  • In the present study, all of the treadmill exercise-trained SHR expressed clear adaptive changes such as reduced resting heart rate and blood pressures, LPOA, homocysteine Therefore, treadmill exercise was sufficient to induce physiological adaptation in the SHR. Endurance training is known to induce physiological cardiac hypertrophy, while hypertension induces patho logical cardiac hypertrophy that increases cardiomyocyte apoptosis. The pathological adaptation to pressure overload has also been associated with a further increase in the expression of several marker genes including cardiomyocyte ET-1 in the SHR, but not in the exercise-trained SHR. Additionally, there is an increase in the endothelial nitricoxide synthases (eNOS) protein expression of soleus, gastrocnemius, and extensor digitorum longus muscle in the exercise-trained SHR but not in the SHR in the present study. Thus, compared to pathological adaptation to pressure overload, physiological adaptation to exercise training is associated with distinct alterations in cardiac and molecular phenotypes. based on these results, exercise training improves hypertension by cardiovascular regulating genes and hemodynamic parameters.

  • In this paper, we present a method that integrates a Grammar Transducer as an external language model to enhance the accuracy of the pre-trained Korean End-to-end (E2E) Automatic Speech Recognition (ASR) model. The E2E ASR model utilizes the Connectionist Temporal Classification (CTC) loss function to derive hypothesis sentences from input audio. However, this method reveals a limitation inherent in the CTC approach, as it fails to capture language information from transcript data directly. To overcome this limitation, we propose a fusion approach that combines a clause-level n-gram language model, transformed into a Weighted Finite-State Transducer (WFST), with the E2E ASR model. This approach enhances the model's accuracy and allows for domain adaptation using just additional text data, avoiding the need for further intensive training of the extensive pre-trained ASR model. This is particularly advantageous for Korean, characterized as a low-resource language, which confronts a significant challenge due to limited resources of speech data and available ASR models. Initially, we validate the efficacy of training the n-gram model at the clause-level by contrasting its inference accuracy with that of the E2E ASR model when merged with language models trained on smaller lexical units. We then demonstrate that our approach achieves enhanced domain adaptation accuracy compared to Shallow Fusion, a previously devised method for merging an external language model with an E2E ASR model without necessitating additional training.

  • As of December 2013, 63 distance education training centers has been operating in the form of private, university affiliated and national/public centers. LMS is related to distance training quality as the system because distance education training centers are managing training by using LMS. In this paper, LMS functions of distance education training centers were analyzed to enhance the quality of distance training. In results of the analysis, it is showed 70.07%, 72.09% and 70.41% that implementation ratio of necessary LMS functions for trainee, manager and tutor. Functions of the lowest implementation ratio were "training support" of trainee mode, "statistics management" of manager mode and "communication" of tutor mode. The results of this paper will be helped to improve LMS for effective distance training of distance education training centers.
