The purpose of this study was to determine the effects of associative drawing task in a Korean bilingual aphasic. The subject is a 41-year old male and lived and was educated in the United States for over 25 years(from the age of 14 through 39). His former occupation was a psychiatrist. He has had a massive lesion in the occipital lobe. This study focused on improving his spontaneous language performances by associative drawing task. The associative drawing task along with spontaneous speech is to help the subject's cognition. The ten target words in this treatment were familiar words and could be drawn easily. The results were that the associative drawing task was effective on improving the patient's drawing ability-writing ability in English only-and naming performance both in English and Korean. However, the patient's writing ability in Korean did not show any improvement.

This study investigated to the effects of a mental image drawing in RHD patients with left neglect. Three subjects participated in this study. All subjects were right handed and native speaker of korean. In task 1, the patients were presented with visual stimulus card directly above the response sheet and were asked to draw the picture. In task 2, they were presented with items auditorily and asked to draw the picture(mental image drawing). In all experimental conditions, there was no response time limit. The results showed that the subjects showed left neglect leaving some space on the left side in task 1. And the picture was drawn the left side from the right in direction. However, the neglect disappeared in task 2. And the picture was drawn the right side from the left in direction. The results of the present study suggested that a mental image drawing technique can be effective in treating individuals who exhibit left neglect. Also, the picture direction showed that the korean normality was same.

Near-infrared spectroscopy (NIRS) can be used to monitor brain activation by measuring changes in the concentration of oxy- and deoxy-hemoglobin (Hb) by their different spectra in the near-infrared range. Because NIRS is a noninvasive, highly flexible and portable device, it is very suitable to study brain activation when a human repeatedly performs a manipulative task, and possibly provides useful information to construct human adaptive mechatronics (HAM). There is some evidence that the dorsolateral prefrontal cortex (DLPFC) plays a major role in working memory and it is proposed that the use of working memory decreases as a human develops manipulative skills. In the present study, we investigated the activation of the dorsolateral prefrontal cortex (DLPFC) of the brain in Brodmann's areas 9 and 46 in drawing tasks to examine whether NIRS can measure the changes of DLPFC activation as a human develops manipulative skills. Subjects performed a mirror image drawing task and a square drawing task by ones' left hands. In the mirror image task the subject drew following a star shape based on a mirror image of it, but square drawing did not involve mirror image and was estimated to be simpler. The changes of the concentration of oxy-Hb was higher in the mirror image drawing than the square drawing in most subjects. The changes of oxy-Hb decreased as the subject repeated the drawing task in most subjects. In conclusion, The activation of DLPFC measured by NIRS can reflect the brain activity in the development of manipulative skills.

This study attempted to determine the effects of a context-based drawing task on the language expression of a severe Wernicke's and Broca's aphasic. The subjects in this study showed a poor auditory comprehension and naming performance. They also showed paraphasia and perseveration. This study focused on improving language expression by a drawing task based on conversation at hand. Ten target words were chosen which were easily drawnable and familiar to the subjects. The results showed that the context-based drawing task was effective on improving the subjects' confrontation naming ability and expressive language ability in terms of explanation of sentences. In addition, the Broca's aphasic showed improved naming ability when the contextual cues were given and he was supposed to spontaneously name words.

This study investigated undergraduate students' perceptions and mental models of the environment. A total of 192 students were sampled from a university of Gyoungbuk area. The environmental task was administrated to students drew a picture of an environment and explained their drawing. The results are as follows: First, a majority of undergraduate students perceived an environment from a comfortable environment. Second, five mental models emerged from a content analysis of students' responses about environmental drawing. Third, the dominant model was mental model 4, the environment as a place where animals, plants, and humans live. This means that the majority of students perceived a 'relation' rather than 'objects' views of the environment. Therefore, undergraduate students' conceptualizations about environment depends on a view or mental models of the environment which places humans in a sustaining relationship with the environment and its natural resources. The implications of these findings for environmental education are discussed.

In this paper we present an efficient technique for sketch-based 3D modeling using automatically extracted image features. Creating a 3D model often requires a drawing of irregular shapes composed of curved lines as a starting point but it is difficult to hand-draw such lines without introducing awkward bumps and edges along the lines. We propose an automatic alignment of a user's hand-drawn sketch lines to the contour lines of an image, facilitating a considerable level of ease with which the user can carelessly continue sketching while the system intelligently snaps the sketch lines to a background image contour, no longer requiring the strenuous effort and stress of trying to make a perfect line during the modeling task. This interactive technique seamlessly combines the efficiency and perception of the human user with the accuracy of computational power, applied to the domain of 3D modeling where the utmost precision of on-screen drawing has been one of the hurdles of the task hitherto considered a job requiring a highly skilled and careful manipulation by the user. We provide several examples to demonstrate the accuracy and efficiency of the method with which complex shapes were achieved easily and quickly in the interactive outline drawing task.

Tourism industry increasingly rely on information technology (IT) to improve the task performance. Many studies suggested that the evidence of IT showed not only task performance improvement but also organizational performance. Drawing from the resource-based view, technology and task fitness, and marketing orientation theories, this study proposes that IT use influences directly the task performance and proved the effectiveness of IT in the organizations of tourism industry. Further, the innovativeness, resources, and marketing orientation are identified as main determinants of IT use. The use of IT can serve as a catalyst in improving task performance for organizations in tourism industry. Based on data collected from surveying people who work in the tourism industry, the present study shed light on these issues. The findings provide a new perspective of IT effectiveness in the tourism industry. Then, we discussed the theoretical and practical implications.

The purpose of this study was to investigate middle school students' perceptions about global environmental problems using drawings. The study was involved the collection of drawing data from 112 ninth grade students from a middle school in Daegu Metropolitan City. The environment task was administrated to students drew a drawing of an global environmental problems and explained their drawing in their own words. Also, students was asked to write what he or she can do to solve global environmental problems. The results are as follows: First, air pollution is the most important global environmental problem, followed by water pollution, global warming, sea level rise, deforestation, waste, loss of biodiversity, and so on. Second, the students' drawings were characterized into two aspects: One is a macroscopic viewpoint and the other is everyday viewpoint. Third, the students' practical action plan to do solve global environmental problems were walk, public traffic, do not throw trash, plant trees, etc. Educators should take into account the perceptions of global environmental problems and teaching-learning strategies to enhance students' understanding of global environment.

Tube drawing process is more sensitive to the friction coefficient but it is a hard task to analyze it's disposition qualitatively. This paper aims to calculate the mean friction coefficient from author's direct equation which amended from general rod drawing process, and compare the result with SACHS' or WILLIAM'S. From this study, the thickness change was inspected in multi-pass drawing. The thickness affected with the mean friction coefficient and the thickness was deformed more thicker than initial thickness on the condition of good lubrication. For the sake of a good estimation of mean friction coefficient, the radial force of die must be considered when the drawing process has some more area reduction about more than 10 percents.
