Objective : The purpose of this study was to verify the effectiveness of home-visit occupational therapy in stroke patients. Methods : Two patients with stroke who applied for home-based occupational therapy services at a health center in Seoul were enrolled. The home-visit occupational therapy program evaluates the subject's daily living, task performance, cognitive, and emotional functions, sets occupational therapy goals and plans interventions based on a client-centered approach. Occupational therapy programs consisted of 12 sessions based on the client's major problems. Results : COPM scores improved in both cases, there was an improvement in COPM scores, and in Case 2 there were improvements in MBI and K-MMSE scores. There was also an improvement in KGDS scores in Case 1. Conclusion : Home-visit occupational therapy was found to be effective in improving daily activities, cognition, and mental function of stroke patients. During home and community integration, continuous and continuous rehabilitation services need to be activated from institutional rehabilitation to community-based rehabilitation. Active home-visit occupational therapy is needed to promote physical, cognitive, mental and social access in stroke patients discharged from hospitals.

Geodesign was suggested by Dangermond(2009) as a next paradigm of GIS to be a future basis for spatial planning and design. Ko(2015) also suggested a geodesign methodology that uses spatial information from a landscape designer's perspective. Spatial planning and design fundamentally require creativity and efficiency but Ko's methodology did not include the creativity aspect. To complement the deficiency, this paper expand the research scope to deal with a designer's cognitive limits and to provide better experiences for the landscape designers. An interface was designed to improve the designer's creativity based on interactions that were derived from a script of landscape design. The expanded methodology for both efficiency and creativity is suggested for the interface by analyzing preceding researches. ESRI's GeoPlanner for ArcGIS, as a first geodesign software, is compared to improve the interface in terms of creativity. One of the difficulties as a thesis is that it is not easy to measure the improvement of design creativity physically and quantitatively. This paper tried to eliminate any stumbling block in supporting creativity and to help designers find new orders in design subconsciousness and to reach a new concept. In addition, the interface to express instantaneous design ideas would be a guide to overcome the designer's cognitive limits.

According to development of technology for media, observers try to watch the realities from images, as follows, 3D imaging has been extremely developed. 3D image gives depth in the image, observers feel in nature. Different image perception from left and right eyes make the 3D image. Anaglyph which is one of the ways to make an image of three dimensions is for obtaining an image of three dimensions by using color filter glasses. Anaglyph has a little amount of calculation and is easy to make, and it has a good point that anaglyph can be used in more wide field because it can create an image of three dimensions to the output of print like printed matter. However, the phenomenon of retinal rivalry can cause a feeling of fatigue because a difference of brightness of the left image and the right image happen. The way to reduce this problem is made by cutting down a difference of brightness. In the result, retinal rivalry can be reduced. We reduced a difference of the brightness of the left and the right image by utilizing the brightness and average of the original image to reduce retinal rivalry and we made better colors of anaglyph by using the way that we keep the hue caused by a change of brightness and supplement saturation about color distortion which is created at that time.

Evaluation activities are beneficial for learning or training. However, they are not actively used due to concerns about the evaluation accuracy of non-experts. Although there are methods to improve accuracy, there is a limitation that additional procedures or processes are required in addition to evaluation. In this study, we aimed to improve evaluation accuracy of non-expert by using common evaluation items and assigning weights based on differences from expert scores. In Study 1, we conducted a simulation with 50 non-experts evaluating essays. Our findings indicate that when non-experts' evaluation methods are different from those of experts, our proposed method using a single common evaluation item improves assessment accuracy. In Study 2, we analyzed data from experimental situation in which non-expert evaluated each other's essays. Consistent with Study 1, our proposed method effectively improved assessment accuracy when non-experts' evaluation methods differed from those of experts. In the discussion section, we addressed the applicability of the method proposed in this study in real world settings.

The purpose of this study was to investigate high school students' understanding of acid-base related concepts using three different titration technologies. The test population was composed of 209 students from three classes in the 10th grade. The different titration experiments using indicator, or pH-meter or MBL were performed in each class unit, respectively. The analyses of the effect on the understanding of different titration technologies were carried out by comparing the mean scores of the concept test taken before and after the titration for the three groups. The results of the acid-base related concept test indicated that statistically significant effects on the understanding of the concepts were shown by all groups. Comparing the effect on the comprehension of the three groups, the MBL group showed the most significant effect, while the pH-meter group showed the least significant. It was also attempted to analyze the effect on comprehension of the concepts by the cognitive and the motivational levels of students. This study revealed that the students in the formal operation stage showed higher understanding of the acidbase related concepts, while those in the concrete operation stage showed lower comprehension. It was also shown that the students at the active motivational level scored higher in comprehension than those who had a low score. The results of this study implied that each group showed differently enhanced comprehension of concepts by titration technologies. Therefore, teachers need to promote an appropriate experiment technology for the cognitive and motivational levels of students as well as try to help students express freely their own perspectives.
