The purpose of this study was to examine the effect of motion activities utilizing various of materials(ex, using fabric, stone, wood, percussion instrument) on young children's emotional intelligence and its subareas, including the an ability to identify and control their on emotions, self-motivating skills, the ability to identify other's emotional state, and interpersonal skills. The subjects in this study were 60, 5-year-old preschoolers attending D kindergarten in U city. The experiment w3s implemented in an experimental group 36 times for 12 weeks, three times a week, by using various of materials. The control group was only exposed to the routine phvsical programs according to the 6th curricula. To see if there were any disparities between pretest and posttest results, paired t-test was carried out, and t-test by independent sampling was employed to find out intergroup gaps. Following are the findings of this study. First, the motion activities utilizing various materials made a significant difference to the young children's emotional intelligence. Second, the motion activities atilizing various materials was effective for their ability to identify their own emotions, ability to control their own emotions and self-motivation. Third, the motion activities utilizing various materials didn't bring any significant changes to the young children's ability to identify other's emotions and their interpersonal skills. Thus, motion activities that took advantage of various materials had a positive impact on the development of the emotional intelligence of the young children. We suggest that more attention be paid to motion activities and the formulation of various and systematic motion programs as a way to raise emotional intelligence.

Objectives : The purpose of this study was to evaluate the effect of social skills training (SST) for children in two different community settings, an elementary school and a child community center. Methods : Two separate groups of 15 children (10 boys and 5 girls) and 13 children (4 boys and 9 girls) participated in a SST program twice per week at an elementary school and a child community center, respectively. Age range of participants was from 8 to 10 years. Sixty-minute-long sessions of SST were continued twice per week for 4 weeks. Korean-Child Behavior Checklist (K-CBCL), Conner's Rating Scales, Korean-Attention-Deficit Hyperactivity Disorder Rating Scale (K-ARS), Social Skills Rating System (SSRS), and Matson's Evaluation of Social Skills with Youngsters (MESSY) were evaluated by their parents before and after the SST program. Results : Pre-and-post analysis of SST indicated no significant statistical differences in the elementary school group. However, the child community center group showed significantly increased scores for total social ability (p<.05) and decreased scores for attention problem (p<.05) on the K-CBCL. In addition, scores of MESSY were significantly increased (p<.05). These differences between the two groups were still significant after controlling pre-SST scores ; and difference of SST scores between the two groups disappeared after SST. Conclusion : Results suggest that SST in the community setting is an effective tool for prevention of social deficits and problems in attention by promoting social function and attention.

As an important research direction of the application of computer science in the medical field, the automatic generation technology of radiology report has attracted wide attention in the academic community. Because the proportion of normal regions in radiology images is much larger than that of abnormal regions, words describing diseases are often masked by other words, resulting in significant feature loss during the calculation process, which affects the quality of generated reports. In addition, the huge difference between visual features and semantic features causes traditional multi-modal fusion method to fail to generate long narrative structures consisting of multiple sentences, which are required for medical reports. To address these challenges, we propose a multi-feature optimization Transformer (MFOT) for generating radiology reports. In detail, a multi-dimensional mapping attention (MDMA) module is designed to encode the visual grid features from different dimensions to reduce the loss of primary features in the encoding process; a feature pre-fusion (FP) module is constructed to enhance the interaction ability between multi-modal features, so as to generate a reasonably structured radiology report; a detail enhanced attention (DEA) module is proposed to enhance the extraction and utilization of key features and reduce the loss of key features. In conclusion, we evaluate the performance of our proposed model against prevailing mainstream models by utilizing widely-recognized radiology report datasets, namely IU X-Ray and MIMIC-CXR. The experimental outcomes demonstrate that our model achieves SOTA performance on both datasets, compared with the base model, the average improvement of six key indicators is 19.9% and 18.0% respectively. These findings substantiate the efficacy of our model in the domain of automated radiology report generation.

With information technology's rapid development, the Internet faces serious security problems. Studies have shown that malware has become a primary means of attacking the Internet. Therefore, adversarial samples have become a vital breakthrough point for studying malware. By studying adversarial samples, we can gain insights into the behavior and characteristics of malware, evaluate the performance of existing detectors in the face of deceptive samples, and help to discover vulnerabilities and improve detection methods for better performance. However, existing adversarial sample generation methods still need help regarding escape effectiveness and mobility. For instance, researchers have attempted to incorporate perturbation methods like Fast Gradient Sign Method (FGSM), Projected Gradient Descent (PGD), and others into adversarial samples to obfuscate detectors. However, these methods are only effective in specific environments and yield limited evasion effectiveness. To solve the above problems, this paper proposes a malware adversarial sample generation method (PixGAN) based on the pixel attention mechanism, which aims to improve adversarial samples' escape effect and mobility. The method transforms malware into grey-scale images and introduces the pixel attention mechanism in the Deep Convolution Generative Adversarial Networks (DCGAN) model to weigh the critical pixels in the grey-scale map, which improves the modeling ability of the generator and discriminator, thus enhancing the escape effect and mobility of the adversarial samples. The escape rate (ASR) is used as an evaluation index of the quality of the adversarial samples. The experimental results show that the adversarial samples generated by PixGAN achieve escape rates of 97%, 94%, 35%, 39%, and 43% on the Random Forest (RF), Support Vector Machine (SVM), Convolutional Neural Network (CNN), Convolutional Neural Network and Recurrent Neural Network (CNN_RNN), and Convolutional Neural Network and Long Short Term Memory (CNN_LSTM) algorithmic detectors, respectively.

Objectives: Previous studies have found that the oral health of seniors can affect their physical nutrition and quality of life (QoL). Additionally, poor oral health can lead to the development of dementia, which is associated with decreased cognitive function. This study aimed to examine the impact of geriatric oral health (GOH) on the QoL of Korean seniors and the mediating effects of cognitive function. Methods: We used data from the seventh Korean Longitudinal Study of Aging conducted in 2018. In total, 4049 seniors were included in our study. We analyzed the impact of GOH on QoL according to 5 mediating domains of cognitive function and control variables. To examine each path of mediating effects, bootstrapping with 5000 iterations was performed with 95% confidence intervals. Results: Our findings revealed that good GOH had a positive effect on the QoL of seniors. Also, better GOH corresponded to a higher degree of cognitive function within all 5 domains: orientation, memory registration, attention/calculation, memory recall, and language and visuospatial ability. In addition, 3 domains of the 5 domains (attention/calculation, memory recall, and language and visuospatial ability) had significant mediating effects on the relationship between GOH and QoL. Conclusions: This study suggests that adequate management of GOH is crucial for promoting a better QoL and a high degree of cognitive function among seniors. To prevent cognitive impairment, such as dementia, future studies should take a more targeted approach by examining data according to each cognitive domain and various socio-demographic factors.

The concept of sharing economy has received rich attention in recent years. As a typical type of business model in the sharing economy, online short rent has been paid attention by both industry and academia. In this study, we find trust to be a critical determinant to the success of online short rent platforms. Based on three dimensions of trust theory, i.e., ability, benevolence and integrity, we investigate the factors influencing tenant' willingness to participate in online short rent. We further examine the extent to which trust can influence the number of sales and comments of rooms listed at online short-term rent platforms, which can represent tenant' willingness to participate in the sharing economy. The results show that the trust dimensions represented by a landlord's personal characteristics have significant positive correlations with the number of sales and comments. For example, the real name authentication and the sesame score can represent the trust integrity; online replay ratio and the average confirmation time representing the trust sincerity, and the order acceptance ratio representing the trust ability. On this basis, we proposed some recommendations for both platforms and landlords. For example, the landlords can improve the tenants' trust by authenticating his/her real name, replying actively and timely. For platforms, when they make housing list ranking rules, they can take the landlord's personal attributes that may affect trust into consideration. Moreover, platforms can also allow landlords to supply value-added services to improve service quality and ultimately promote the virtuous circle of the platform ecosphere. Through conducting the empirical research on a particular application of the sharing economy, we aim to fill the research gap of this field in China and provide theoretical and practical contributions to the future development of online short rent.
