De novo drug design is the process of developing new drugs that can interact with biological targets such as protein receptors. Traditional process of de novo drug design consists of drug candidate discovery and drug development, but it requires a long time of more than 10 years to develop a new drug. Deep learning-based methods are being studied to shorten this period and efficiently find chemical compounds for new drug candidates. Many existing deep learning-based drug design models utilize recurrent neural networks to generate a chemical entity represented by SMILES strings, but due to the disadvantages of the recurrent networks, such as slow training speed and poor understanding of complex molecular formula rules, there is room for improvement. To overcome these shortcomings, we propose a deep learning model for SMILES string generation using variational autoencoders with self-attention mechanism. Our proposed model decreased the training time by 1/26 compared to the latest drug design model, as well as generated valid SMILES more effectively.

In most self-center braces, decreasing residual deformation is possible only by increasing pretension force, which results in lower energy dissipation capacity. On the other hand, increasing energy dissipation capacity means higher values of residual deformation. The goal of this research was to find the best design for a self-centering buckling restrained brace (SC-BRB) system by balancing self-centering capability and energy dissipation. Three, six, and nine-story structures were investigated using OpenSees software and the TCL programming language to achieve this goal. For each height, 62 different SC-BRBs were considered using different values for the pretension force of cables, the area of the buckling restrained brace (BRB) core plate, and the yield stress of the core plate. The residual deformation and dissipated energy of all the models were calculated using nonlinear analyses after cyclic loading was applied. The optimum design for each height was determined among all the models and was compared to the structure equipped with the usual BRB. The residual deformation of the framed buildings was significantly reduced, according to the findings. Also the reduction of the energy dissipation was acceptable. The optimum design of SC-BRB in 6-story building has the most reduction percent in residual deformation, it can reduce residual deformation of building 83% while causing only a 57% of reduction in dissipated energy. The greatest reduction in residual deformation versus dissipated energy reduction was for the optimum SC-BRB design of 9-story building, results indicated that it can reduce residual deformation of building 69% while causing only a 42% of reduction in dissipated energy.

The purpose of this study was to develop design guidelines on the learning analytics which can help to promote students' self-regulated learning (SRL) strategies in MOOCs learning environments. First of all, to develop the first draft of design guidelines, relevant literature review and case analysis on current MOOCs platforms such as edX, K-MOOC, Coursera, Khan Academy and FutureLearn were conducted. Then, to validate the design guidelines, expert reviews (validation questionnaires and in-depth interviews) and learner evaluation (in-depth interviews) were conducted. Through the recursive validation, the design guidelines were finalized. Overall, the final version of design guidelines on learning analytics to facilitate SRL strategies was suggested. The final design guidelines consist of 15 items in 10 categories related to the information analyzed based on individual student's learning behaviors and activities on MOOCs environments. Moreover, the results of interview also revealed that the social comparisons, learning progress reports, and personalization might contribute to the improvements of their SRL competences. This study has an implication that MOOCs could offer a higher success or completion rate to students with low SRL skills by taking advantage of the information on learning analytics

Purpose: The purpose of this study was to find out long-term effects of the self-help program including the stretching exercise of patient with fibromyalgia, Our findings will have the way for the nursing intervention for reduction of fibromyalgia symptoms and physical disability. Method: The research design was pre-post test design of an experimental group. 41 subjects with fibromyalgia were subjected to our study. Participants of this program were participated with a group of 8 to 12 members with duration of two and half hours for two years(March. 1998 to January. 2000). The Self-efficacy was measured by the Self-efficacy scale. Symptom was converted to scores based on visual analog scale. Physical disability was measured with questionnaires prepared by researchers of this study. Data were collected by the structured interview using questionnaires after self-help program and after 8 months. Data were analyzed by frequency, $x^2$-test and repeated t-test using SPSS 11.0 for windows. Result: Daily activities were not changed but self-described symptom was changed after 8 months. After 8 months, exercise performance along with taking drugs showed significantly lowering trend with respect to self-help program. Relieved symptom of patient with fibromyalgia has continued until 8months after 6weeks program of self-help. Also Promoted self-efficacy of patient with fibromyalgia continued after 8months. After 8 months, in self-described physical disability has showed significantly worse off than after self-help program. Conclusion: In this study, the long-term effects after self-help program for fibromyalgia have showed all symptoms and self-efficacy except exercise performance and physical disability. Therefore, it will be desirable that application of the follow up program with peer group meeting.
