The purpose of this study is to identify how education and activities of urban forest healing programs affect emotional rest (healing recovery environment awareness, restoration of attention, and leisure life satisfaction). To this end, 38 people were divided into experimental groups (forest healing program education and practice), and control groups (non-program participation). As a result of the study, in the case of the experimental group, emotional rest factors such as healing recovery environment perception, attention recovery, and satisfaction with leisure activities after the program were statistically significantly improved, and in the case of the control group, there was no change in emotional rest after the program. In addition, there were differences between groups in both pre and post regarding the difference in emotional rest between the participant groups, and the difference in emotional rest afterwards was much larger than the pre-difference. In conclusion, people who receive regular education on forest healing and have done actual forest healing activities experience higher emotional rest than those who do not. This suggests that continuous motivation and regular practice can raise awareness of the healing recovery environment, promote attention recovery, and have a positive effect on leisure life through appropriate programs rather than simply taking a walk.

Underwater images usually have various problems, such as the color cast of underwater images due to the attenuation of different lights in water, the darkness of image caused by the lack of light underwater, and the haze effect of underwater images because of the scattering of light. To address the above problems, the channel attention mechanism, strengthen-operate-subtract (SOS) boosting mechanism and gated fusion module are introduced in our paper, based on which, an underwater image recovery network is proposed. First, for the color cast problem of underwater images, the channel attention mechanism is incorporated in our model, which can well alleviate the color cast of underwater images. Second, as for the darkness of underwater images, the similarity between the target underwater image after dehazing and color correcting, and the image output by our model is used as the loss function, so as to increase the brightness of the underwater image. Finally, we employ the SOS boosting module to eliminate the haze effect of underwater images. Moreover, experiments were carried out to evaluate the performance of our model. The qualitative analysis results show that our method can be applied to effectively recover the underwater images, which outperformed most methods for comparison according to various criteria in the quantitative analysis.

Objectives: To examine the opinions regarding recovery and assess their will to recover in outpatients with schizophrenia. Methods: Total 98 stable outpatients with schizophrenia were enrolled. To investigate the outpatients' opinions regarding recovery, we asked the subjects to write down the ways they could think they had recovered from their current disease. We classified their answers and chose final 39 statements. Using this questionnaire, they were asked to what extent they agreed with each statement. Moreover, the Recovery Assessment Scale (RAS) was used to measure the subjects' will to recover. Results: Many of the 39 subjects who were surveyed about their opinions on recovery agreed on 11 statements about taking medicine, social life, daily life, social functioning, positivity about life (happiness, hope, confidence, and tranquility), symptoms, occupation, and self-control. The RAS score showed a significant correlation with age (r=-0.26, p<0.01), age at onset (r=0.26, p<0.01), duration of illness (r=-0.52, p<0.01), and number of hospitalization (r=-0.46, p<0.01). Conclusion: This study shows that positivity about life is an important part of the patients' subjective recovery criteria in schizophrenia. Therefore, if clinicians pay more attention to this part of subjective recovery, it would strengthen the patients' will for recovery.

The recovery of reasonable depth information from different scenes is a popular topic in the field of computer vision. For generating depth maps with better details, we present an efficacious monocular depth prediction framework with coordinate attention and feature fusion. Specifically, the proposed framework contains attention, multi-scale and feature fusion modules. The attention module improves features based on coordinate attention to enhance the predicted effect, whereas the multi-scale module integrates useful low- and high-level contextual features with higher resolution. Moreover, we developed a feature fusion module to combine the heterogeneous features to generate high-quality depth outputs. We also designed a hybrid loss function that measures prediction errors from the perspective of depth and scale-invariant gradients, which contribute to preserving rich details. We conducted the experiments on public RGBD datasets, and the evaluation results show that the proposed scheme can considerably enhance the accuracy of depth prediction, achieving 0.051 for log10 and 0.992 for δ<1.25³ on the NYUv2 dataset.

Although the generic implementation of aqueous two-phase systems (ATPS) processes for the recovery of biological products has been exploited for several years, this has not resulted in a wide adoption of the technique. The main reasons involve the poor understanding of the mechanism governing phase formation and the behavior of solute partitioning in ATPS processes, the cost of phase forming polymers, and the necessary extended time to optimize the technique. In this review paper, some of the practical disadvantages attributed to ATPS are addressed. The practical approach exploited to design ATPS processes, the application to achieve process integration, the extended use for the recovery of high-value products, and the recent development of new low-cost ATPS, are discussed. It is proposed that the trend of the practical application of ATPS processes for the recovery of biological products will involve the purification of new high-value bioparticulate products with medical applications. Such a trend will give new impetus to the technique, and will draw attention from industries needing to develop new, and improve existing, commercial processes.

Recently, microturbines have received attention as a small-scale distributed power generator. Since the exhaust gas carries all of the heat release, the microturbine CHP (combined heat and power) system is relatively compact and easy to maintain. Generating hot water or steam is usual method of heat recovery from the microturbine. In this work, a heat recovery unit producing hot water was installed at the exhaust side of a 30 kW class microturbine and its performance characteristics following microturbine power variation was investigated. Heat recovery performance has been compared for different operating conditions such as constant hot water temperature and constant water flow rate. In particular, the influence of water flow rate and hot water temperature on the recovered heat was analyzed.

Many techniques have been developed for reconstruction of the hand; however, less attention has been paid to foot reconstruction techniques. In particular, reconstruction of the forefoot and big toe has been considered a minor procedure despite the importance of these body parts for standing and walking. Most of the weight load on the foot is concentrated on the forefoot and big toe, whereas the other toes have a minor role in weight bearing. Moreover, the forefoot and big toe are important for maintaining balance and supporting the body when changing directions. Recently, attention has been focused on the aesthetic appearance and functional aspects of the body, which are important considerations in the field of reconstructive surgery. In patients for whom flap reconstruction in the forefoot and big toe is planned, clinicians should pay close attention to flap survival as well as functional and cosmetic outcomes of surgery. In particular, it is important to assess the ability of the flap to withstand functional weight bearing and maintain sufficient durability under shearing force. Recovery of protective sensation in the forefoot area can reduce the risk of flap loss and promote rapid rehabilitation and functional recovery. Here, we report our experience with two cases of successful reconstruction of the forefoot and big toe with a sensate anterolateral thigh flap, with a review of the relevant literature.

This study aims to empirically examine the effect of feedback on attention recovery. The role of feedback has been proven to be positive in particular to extend the limitation of attention resource. We studied the impact of feedback on attention by varying its type and modality. An experimental system was developed to observe how accurately the participants performed the pattern-matching task with differential feedback provided on a real-time basis based on the ADHD diagnostic model. Six university students participated in this study with 6 different feedback conditions and controlled conditions. The participants experienced the feedbacks before experiment. They was asked two hundred tasks in four feedback conditions. The difference of feedback effect according to different modality is to find within a subject. The results indicated that the combined feedback of cognitive with perceptual stimulus led better performance than the combined of perceptual feedbacks.
