This study is a similar experimental study using parallax design before and after the non-equality control group conducted to investigate the effects of the Mental health guardian program for mentally disabled people on the awareness of rights, empowerment, and resilience of mentally disabled people. The mentally handicapped persons who participated in the mental health guardian program were significantly higher in the awareness of the rights of the handicapped compared to the mentally handicapped persons who did not participate. In terms of empowerment, there was no significant difference between the two groups. In terms of resilience, the experimental group significantly increased compared to the control group. Among the sub-areas of resilience, excluding spirituality, difficulty overcoming, self-competence, learning and self-financing, basic functions, overall life satisfaction, new potential, advocacy and fullness all significantly increased. It has been shown to be effective in increasing the resilience of the disabled. In this study, the reason why mental health guardian program is effective for awareness of rights and resilience is not a one-way education, but a participatory curriculum in which a person with mental disabilities who participated in the education finds and corrects the wrong news and creates a card news again. It seems to be because it did. As a result of this study, it seems that the mental health guardian program has contributed to enhancing the recognition of the rights of the mentally impaired and enhancing resilience.

Our society is moving from a monocultural society of a homogeneous nation to a multi-cultural society as a lot of foreigners are flowing into the country with the advent of globalization and with an effort to secure labor force for economic growth. So, multi-cultural families composed of members using different languages spring up everywhere, but the children in these multi-cultural families have difficulties in acquiring Korean language and are socially maladjusted because of the bilingual environment. The goal of this study is to help enhance the language capabilities and socialities of the children in the multi-cultural families through fine arts using artistic methods. The study method was to analyze the high-quality effects of the fine arts with the theoretical research materials and theses showing the real conditions of the multi-cultural families. And I proposed some ways to improve the linguistic abilities and socialities of the children in the multi-cultural families with the utilization of fine arts. As a result, Firstly, An active use of the bilingual instructors and artistic multimedia is educationally necessary to overcome language restrictions. Secondly, Various ways to utilize fine arts are necessary to improve learning abilities of other subjects. Thirdly, Artistic plays and experiential activities need to be largely applied to education to enhance the abilities of emotional control and socialities. Finally, Integrated culture and art education is essential not only for creativities and socialities but also for personalities for community life.

Environmental and growth factors such as light intensity, vapor pressure deficit, and leaf area index are important variables that can change the transpiration rate of plants. The objective of this study was to compare the transpiration rates estimated by modified Penman-Monteith model and artificial neural network. The transpiration rate of paprika (Capsicum annuum L. cv. Fiesta) was obtained by using the change in substrate weight measured by load cells. Radiation, temperature, relative humidity, and substrate weight were collected every min for 2 months. Since the transpiration rate cannot be accurately estimated with linear equations, a modified Penman-Monteith equation using compensated radiation (Shin et al., 2014) was used. On the other hand, ANN was applied to estimating the transpiration rate. For this purpose, an ANN composed of an input layer using radiation, temperature, relative humidity, leaf area index, and time as input factors and five hidden layers was constructed. The number of perceptons in each hidden layer was 512, which showed the highest accuracy. As a result of validation, $R^2$ values of the modified model and ANN were 0.82 and 0.94, respectively. Therefore, it is concluded that the ANN can estimate the transpiration rate more accurately than the modified model and can be applied to the efficient irrigation strategy in soilless cultures.

The purpose of this study was to investigate the effects of using open-ended problems in ability-level activities in mathematics instruction and to draw some informative conclusions in order to improve the practice of teaching and learning mathematics in the elementary school. To fulfill the purpose, the research questions were established as follows: 1. Is there any difference between the academic achievements of the experimental group(doing ability-level activities using open-ended problems) and the control group(doing general ability-level activities)? 2. Which sub-group(grouped by achievement score in pretest) get affected most by ability-level activities using open-ended problem in the experimental group? 3. What kinds of responses do students show in their ability-level activities using open-ended problems? By applying t-test and analysing the response, the conclusions were drawn as follows: First, using open-ended problems in ability-level activities has positive effects on the academic achievement of the experiment group. The mean of posttest scores of the experiment group was statistically meaningfully higher(p<.05). Second, using open-ended problems in ability-level activities affect most to the achievement of lower sub-group in the experiment group. The mean of posttest scores of lower sub-group in the experiment group was statistically meaningfully higher than that of control group(p<.05). Third, students showed various and creative response in their ability-level activities using open-ended problems.

Recently, public interest in virtual reality (VR) and augmented reality (AR) has increased. Therefore, computer graphics-related research has been actively conducted. This has included research on virtual space related to human posture implementation. However, such research has focused on general posture in humans. This paper presents a system with reference to the basic posture in sports climbing and the inverse kinematics method for generating the positions and behavior of virtual characteristics in a three-dimensional virtual space. The simulation based on the inverse kinematics method, produced with an inverse kinematics solver and initial pose animation from motion capture, provides realistic and natural movement. We designed a simulation system to generate correct posture and motions similar to those in sports climbing by applying the basic procedure of sports climbing. The simulation system provides help for producing content about sports climbing, such as learning programs for novice climbers and sports climbing games.

Background : Behavioral stress has been suggested as one of the significant factors that is able to disrupt physiological systems and cause depression as well as changes in various body systems. The stressful events can alter cognition, learning, memory and emotional responses, resulting in mental disorders such as depression and anxiety. Results : We used a restraint stress model to evaluate the alteration of behavior and stress-related blood parameter. The animals were randomly divided into two groups of five animals each group. Furthermore, we assessed the change of body weight to evaluate the locomotor activity as well as status of emotional and anxiety in mice. After 7 days of restraint stress, the body weight had significantly decreased in the restraint stress group compared with the control group. We also observed stress-associated behavioral alterations, as there was a significant decrease in open field and forced swim test, whereas the immobilization time was significantly increased in the stress group compared to the control group. We observed the morphological changes of neuronal death and microglia by immunohistochemistry and western blot. In our study restraint stress did not cause change in neuronal cell density in the frontal cortex and CA1 hippocampus region, but there was a trend for an increased COX-2 and iNOS protein expression and microglia (CD11b) in brain, which is restraint stress. Conclusion : Our study, there were significant alterations observed in the behavioral studies. We found that mice undergoing restraint stress changed behavior, confirming the increased expression of inflammatory factors in the brain.

In this paper, we propose a novel intelligent headlight control (IHC) system which is durable to various road lights and camera movement caused by vehicle driving. For detecting candidate light blobs, the region of interest (ROI) is decided as front ROI (FROI) and back ROI (BROI) by considering the camera geometry based on perspective range estimation model. Then, light blobs such as headlights, taillights of vehicles, reflection light as well as the surrounding road lighting are segmented using two different adaptive thresholding. From the number of segmented blobs, taillights are first detected using the redness checking and random forest classifier based on Haar-like feature. For the headlight and taillight classification, we use the random forest instead of popular support vector machine or convolutional neural networks for supporting fast learning and testing in real-life applications. Pairing is performed by using the predefined geometric rules, such as vertical coordinate similarity and association check between blobs. The proposed algorithm was successfully applied to various driving sequences in night-time, and the results show that the performance of the proposed algorithms is better than that of recent related works.
