Purpose : This study aims to evaluate the correlation of cognitive function, activities of daily living (ADL), and driving performance in stroke hemiplegic patients residing in Korea. Methods : Subjects of the study were 18 stroke hemiplegic patients admitted to hospitals situated in Seoul. A clock drawing test (CDT), a modified Barthel index (MBI), and a virtual reality driving simulator (Eca faros-driving simulator) were used to examine their cognitive function, their ADL ability, and their driving skills, respectively. Results : Driving skills of stroke hemiplegic patients were shown to be associated with the CDT evaluation tool (r=-.777) (p<.001), but they were found to have any correlation with MBI (r=-.022) (p>.05). Additionally, an individual's CDT showed that the driving simulator evaluation result (pass/fail) could be discriminated with a sensitivity of 100.0 %, a specificity of 40.0 %, and an accuracy of 66.7 %. The result confirmed that the CDT is a useful evaluation tool for screening driving ability in people with stroke. But the MBI did not show any significant results (sensitivity of 62.5 %, specificity of 40.0 %, and predicted the results of the simulator with 50.0 % of accuracy) (p>.05). Conclusion : This study shows that cognitive function influences the driving performance in people with stroke. Driving skills of stroke hemiplegic patients are seen to be highly related to CDT. In the field of driving rehabilitation, these findings could be useful for evaluating driving skills relating to CDT. Furthermore, the study results will set a guideline for domestic occupational therapists to use the evaluation tool for assessing driving abilities in people with stroke.

Internet is being used for several activities by a great range of users. These activities include communication, e-commerce, education, and entertainment. Users are required to register regarding website in order to enroll web activities. However, registration can be done by automated hacking software. That software make false enrollments which occupy the resources of the website by reducing the performance and efficiency of servers, even stop the entire web service. It is crucial for the websites to have a system which has the capability of differing human users and computer programs in reading images of text. Completely Automated Public Turing Test to Tell Computers and Human Apart (CAPTCHA) is such a defense system against Optical Character Recognition (OCR) software. OCR can be defined as software which work for defeating CAPTCHA images and make countless number of registrations on the websites. This study proposes a new CAPTCHA context that is Korean CAPTCHA by means of the method which is splitting CAPTCHA images into several parts with random rotation values, and drawing random lines on a grid background by using Korean characters only. Lines are in the same color with the CAPTCHA text and they provide a distortion of image with grid background. Experimental results show that Korean CAPTCHA is a more secure and effective CAPTCHA type for Korean users rather than current CAPTCHA types due to the structure of Korean letters and the algorithm we are using: rotation and splitting. In this paper, the algorithm of our method is introduced in detail.

The purpose of this study was to investigate the elementary students' views about lab-based science learning. For the purpose of this study, semi-structured interviews were conducted with thirty sixth grade students in 12 classes from two elementary schools located in Daegu City. The interview contents consisted of three major categories. The first category was related to attitude toward science lab, the second was related to lab-based science learning which had four sub-categories; recognizing lesson object, planning experiment, performing experiment, drawing conclusion in lab-based science learning in which the students had ordinary have views and expectations, and the last category was related to students' difficulties and something need to be improved in lab-based science learning. In-depth interviews were performed individually and the interviews were recorded. From the interviews, we found that students, in first category, do like lab-activities more than lectures or instruction-based activities in textbook. Students, in second category, wanted generally more discussion for their own activities rather than teacher's instruction and they wanted teacher' mediation conflicts within small groups and comments for students' experiment results. In the last, most of students had fears for some dangerous reagents and accidents. Based on the results, the study suggested that teacher need to give their students to autonomous discussion opportunities to design and interpret data through teacher' guided questions in inquiry steps, to produce some intimate atmosphere for active interaction in small groups, and to teach the safety education on some dangerous reagents.

The typical Kinetic Family Drawing (KFD) Web database system, a form of prototype system, has been developed, relying on the suggestions from family art therapists, with an aim to handle large amounts of assessment data and to facilitate effective implement of assessment activities. However, unfortunately such a system has an intrinsic problem that it fails to collect clients' behaviors, attitudes, facial expressions, voices, and other critical information observed while they are drawing. Accordingly we propose the ontology based video event analysis and video retrieval system in this paper, in order to enhance the function of a KFD Web database system by using a web camera and drawing tool. More specifically, a newly proposed system is designed to deliver two kinds of services: the client video retrieval service and the sketch video retrieval service, accompanied by a summary report of occurred events and dynamic behaviors relative to each family member object, respectively. The proposed system can support the reinforced KFD assessments by providing quantitative and subjective information on clients' working attitudes and behaviors, and KFD preparation processes.

The purpose of this study is to examine personal characteristics of two elementary students who developed individual interest in science. 201 students of two elementary schools in Seoul participated in questionnaire survey engaged in to investigate students' interest in science, engagements and preference in science-related-activities three times a year. This case study was conducted with seven students who showed typical types of interest in science. Students wrote a photo-journal for 12 weeks. They were interviewed every other week by a researcher. We analyzed two students who developed individual interest. It turns out that RF participated in doing experiments at home, and disassembling and assembling things. Participation of activities was a process of solving curiosity. When he was unable to solve problems, he searches the internet or books. Sometimes he would ask for help from his teacher. JW engaged in activities: drawing, doing experiments at home, and going to informal education center. She communicated with others by using online-offline media. Curious questions were solved by herself. The two students have a tendency to solve problems by themselves. Also, positive science-related activities were going on at home and in school. This study not only give insights and understanding of students who developed individual interest in science but also provide implication for educators to examine personal characteristics of students.

This study was performed to develop dietary education programs for children, by researching the actual conditions of dietary education and its demand aimed at teachers in child centers in Masan. Most of the interviewed teachers were in their 20s(71%) with under 5 years teaching experiences(56.8%), and working in a kindergarten environment(34.9%). The rate of doing dietary education on mealtime was 96.4%. The main items taught pertained to 'not leaving food(20.6%)' and 'washing hands before meals(20.5%)'. The primary teaching method for students with unbalanced eating habits was 'eating after teaching them to understood(76.8%). The primary reward for good behavior was 'using food(76.8%)', usually as 'candy'(50.8%) or 'cookies'(25.8%). The desirable dietary education type was 'during spare moments(52.6%)' and 'at mealtime (23.5%)'. The concepts taught were 'balanced eating(23.2%)' and 'food hygiene(21.2%), and the students were interested in 'the roles of foods and nutrients'(34.5%), 'balanced eating(20.9%)', and 'food hygiene(19.1%)'. Educational activities encompassed 'pictures and drawing(25.7%)', 'fairy tales(23.4%)', 'songs(19.4%)', and 'play(14.1%)'. Also, the activities of most interest were 'fairy tales(29.4%)', 'play(24.4%)', and then 'songs(23.1%)'. The greatest difficulties during dietary education were 'attracting interest from the children(37.8%)' and 'making and purchasing materials(33.9%)'. Approximately, 44.2% of the teachers had experiences in dietary education, and 96.4% stated teachers had the intention to participate in dietary education. They want to address 'child meal direction(23.0%)', 'health problems(22.7%)', and then 'child nutrient requirements (17.3%)'. Also the majority wanted it two times per year(57.6%) or one time per year(30.9%). This study indicated that proper dietary education must be established in child centers by developing various practical dietary education programs and then implementing them.

Number of children cared by child care centers has getting up almost half of the from zero to five year age group in korea. Home care children' activities are reported more active and natural than those of center care children. So this study seek the design guidelines for the residential core model of child care centers as second home in korea. The residential core model by Anita Lui Olds was selected and ten domestic center cases were surveyed for guidelines. Firstly, daily-residential core model is learning by daily life at home, and is equiped with cooking kitchenet and group activity area in group room. Secondly, play-residental core model is learning by playing by self, and is equiped with acting, eating and reading common area clustering two or three group room. Thirdly, eco-residental core model is learning by eco-friendly activities, and is equiped with companying, cooperating and sharing area. Fourthly, project-residental core model is learning by project by self, and is equiped with drawing, experimenting and presenting common area. Fifthly, the space of residential core model is organized with three or four group room and clustering living or common area. The larger the center is, the more the cluster is vertically. Facility area and outdoor playground per child is about 7 and $3m^2$.

This study examines the meaning of classical texts in contemporary society. Drawing on an anthropological investigation of Somun Hakhoe, an association of Korean medicine doctors in South Korea, and its foundational text "Somun Daeyo", the present study explores the interconnectedness of medical texts and medico-social practices in bringing medical tradition into the contemporary era. The themes that author Lee Kyu-joon emphasizes in "Somun Daeyo" are thoroughly embodied in Somun Hakhoe's medico-social practices, such as the study activities based on "Somun Daeyo"(in particular, on Somun Buseol, the five articles written by the author, attached to "Somun Daeyo"), the focus on Buyang theory(扶陽論), and the distinctive feature of composing formula. The ethnographic data collected about the group activities of Somun Hakhoe also demonstrate that the social relationship of the teacher and disciples plays an important role in bringing East Asian medicine into the present. This study articulates the significance of the interaction between the classical text and the medico-social practices around it. The dynamism taking place in the interaction points to the "living tradition" actively flowing rather than being static in the past. This study illustrates the close relationship between medical history and medical anthropology and encourages more studies of classical texts based on the intimate relationship between the two disciplines.
