Purpose: The purposes of this study were to develop the Korean version of the trunk impairment scale (K-TIS) and to examine reliability and responsiveness of the K-TIS in patients with stroke. Methods Subjects of the study were 51 stroke patients (mean age: 57.78 years) recruited from two stroke clinics. For the interrater and test-retest reliability, two raters measured the K-TIS two times using video clips with an interval of 2 weeks. For the responsiveness, intensive physical therapy training was provided to all participants 2 times a day for one month or three months depending on the onset of the stroke and the admission rules of the two clinics. Inter-rater reliability and test-retest reliability of the K-TIS three subscales (static sitting balance, dynamic sitting balance, and coordination) scores and total scores were examined using intra-correlation coefficient ($ICC_{3,1}$) and Pearson's correlation coefficient (r). To examine responsiveness, the minimally important difference (MID) was calculated with effect size. Results: Inter-rater reliability of the K-TIS subscales and total scores were all high (ICC3,1=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, $ICC_{3,1}$=0.805-0.901 and r=0.806-0.903, and the MID for acute and post-acute as well as chronic stroke patients remained in the mean change range. Conclusion: It is suggested that the K-TIS might be used for clinical and research purposes as a standardized tool for stroke patients. In addition, it can also be useful in establishment of treatment goal(s) and planning treatment program(s) for patients with stroke.

Along with the development of high-speed, wired and wireless Internet technology, various harmful images in a form of photos and video clips have become prevalent these days. In this paper, we suggest a method of automatically detecting adult images by extracting woman's nipple areas which represent obscenity of the image. The suggested algorithm first segments skin color areas in the $YC_bC_r$ color space from input images and extracts nipple's candidate areas from the segmented skin areas through the suggested nipple map. We then select real nipple areas by using geometrical information and determines input images as harmful images if they contain nipples. Experimental results show that the suggested nipple map-based method effectively detects adult images.

Objectives : The purpose of this study was to examine the oral health care and educational needs of college students in an effort to give some suggestions on the development of oral health educational media. It's basically meant to boost the efficiency of oral health education geared toward college students. Methods : The subjects in this study were 500 students at seven different colleges located in Daejeon and South Choongcheong Province. After a survey was conducted, frequency analysis and ANOVA were utilized to analyze the collected data. And the records of the in-depth interviews of 10 students were analyzed as well. Results : The gender of the students and whether their major was linked to health or not made differences to their knowledge of dental caries. And there was nothing to affect their knowledge of periodontal diseases except whether their major was related to health or not. They didn't have a good knowledge of periodontal diseases, and they just regarded toothbrushing as a means to prevent dental caries and periodontal diseases. They preferred to acquire knowledge over the Internet. Conclusions : College students who don't know well about periodontal diseases should be given an opportunity to learn about periodontal diseases and diverse ways of preventing dental caries and periodontal diseases other than toothbrushing. As the college students preferred to surf the Internet, educational programs should be developed in the form of video clips that can be found over the Internet, and more aggressive publicity is required via SNS, etc.

This study examines the interaction effects between branded contents' ending types(happy ending, non-happy ending) and the level of product involvement(high involvement, low involvement) on consumer's negative responses. Results suggest that the level of product involvement had no significant effect on consumer responses since product on video clips was not closely linked to the contents' message. Selective empathy is identified as the happy ending type of branded contents had a greater effect on consumer's negative responses than the non-happy ending type of. It is an apparent new phenomenon shown among the young after 2000s. Moreover, the interaction between contents' ending types and the level of product involvement had a significant effect on consumer's negative responses. Two interaction terms (i.e. happy ending and low product involvement; non-happy ending and high product involvement) are the viable message strategies to weaken the consumer responses in terms of 'dislike'.

Recent researches show that the traffic fatality rate in fog is higher than that in rain and snow. In that sense, methods to measure visibility accurately and to notify the measured visibility information to drivers are required. We thus developed a system for measuring the road visibility in realtime by employing CCTV cameras. In this paper, we also propose a wide-area visibility information system through measuring the visibility of every highway by using the developed system. The proposed wide-area visibility information system uses the video clips from the CCTV camera instead of the output from the expensive fog sensor. Hence, we expect that it can reduce the cost of installation and operation dramatically and the measured visibility information has a number of applications.

The purpose of this research is to explore the possibility of geographic education by implementing the map-based geographic education site which mashed up with Google earth by referring the various materials of geographic education which exist in on-line and off-line. In recent years map-based geographic education is required by the radical change of geoweb environments, but there have been few researches in this field. This research is folded up as follows: First, we designed the contents through the textbook analysis and then collect various data related to the contents such as pictures, video clips, conceptual map, etc. which are required to explain the concept. Second, we mashed up the collected data on the Google earth by using the Google's open API. Third, we implemented the geographic education website based on the classification of contents in textbook and the various collected data. This research is important in both that it explores the possibility of the map-based education rather than the text-based education in the geographic field which handles mainly the space and finds the best method to express the various concepts of the textbook on the geoweb environments.

This study examines the fashion illustrations textbooks that have been published in the domestic market, and identifies its characteristics and problems in regards to its use in developing creative students. The purpose of the study is to propose ways to improve the development of the fashion illustration textbooks. The research method of this study are as follows: First, the teaching materials on fashion illustration in Korea were researched to examine the current state of publication. Second, its contents were analyzed to identify its characteristics. Third, an improvement plan of educational materials on fashion illustration in Korea were proposed. As for the scope of study, 18 volumes of fashion illustration teaching materials published in Korea during 2004-2014 were targeted. It should be noted that translated publications, digital fashion illustration materials and teaching materials for specialized and professional organizations were excluded. Conclusions of this study are as follows: First, examination of the textbooks revealed that additional content is needed regarding theoretical understanding of fashion illustration, as well as illustrations of men and children, as there was an insufficient amount of those topics. Second, the contents on the illustration application using current trends were lacking in the unit on illustration application. Accordingly, it is necessary to develop contents that reflect these trends. Lastly, the textbooks should be packaged with compact discs CDs containing video clips to assist students to get a better grasp of the material. The result of this study can be used to develop new teaching materials on fashion illustration, and be utilized as basic information in the curriculum design of fashion illustration.

Generally, dynamic hand gesture recognition is formed through preprocessing step, hand tracking step and hand shape detection step. In this paper, we present advanced dynamic hand gesture recognizing method that improves performance in preprocessing step and hand shape detection step. In preprocessing step, we remove noise fast by using dynamic table and detect skin color exactly on complex background for controling skin color range in skin color detection method using YCbCr color space. Especially, we increase recognizing speed in hand shape detection step through detecting Start Image and Stop Image, that are elements of dynamic hand gesture recognizing, using Guideline. Guideline is edge of input hand image and hand shape for comparing. We perform various experiments with nine web-cam video clips that are separated to complex background and simple background for dynamic hand gesture recognition method in the paper. The result of experiment shows similar recognition ratio but high recognition speed, low cpu usage, low memory usage than recognition method using learning exercise.

Purpose: To explore the effects of action observation combined with modified constraint-induced movement therapy on upper-extremity function and the activities of daily living in subacute stroke patients. Methods: Twenty-four subacute stroke patients were randomly assigned to the experimental group or the control group (n = 12 each). Both groups received therapy based on motor learning concepts, including repetitive and task-specific practice. The experimental group watched video clips for 10 minutes related to tasks performed during modified constraint-induced movement therapy while the control group watched videos unrelated to upper-extremity movement. These programs were performed for 40 minutes a day five times a week for four weeks. Their scores on the Fugl-Meyer assessment of upper extremities (FMA-UE), the action research arm test (ARAT), a motor activity log (amount of use [AOU] and quality of movement [QOM]), and the modified Barthel index (MBI) were recorded. Results: In both groups, all variables were significantly different between the pre-test and post-test periods (p < 0.05). The post-test variables were significantly different within each group (p < 0.05). In the experimental group, the changes between pre-test and post-test scores in the FMA-UE (14.39 ± 4.31 versus 6.31 ± 4.63), the ARAT (16.00 ± 4.73 versus 11.46 ± 3.73), MAL-AOU (1.57 ± 0.15 versus 1.18 ± 0.28), and MBI (27.54 ± 4.65 versus 18.08 ± 8.52) were significantly higher than those of the control group (p < 0.05). Conclusion: These findings suggest that action observation combined with modified constraint-induced movement therapy may be a beneficial rehabilitation option to improve upper-extremity function in subacute stroke patients with moderate impairment.

Purpose : To find out how action observation training for chronic stroke patients affects their balance and body control abilities in the posture seated in the rehabilitation of stroke. Methods : This study was conducted on 30 subjects who were diagnosed with stroke. The group conducted motion observation training through video clips, while the control group only conducted physical training, and the general physical therapy was performed equally by both counties. The static balance was measured using Biorescue and the dynamic balance was measured using Modified Functional Reach Test (MFRT), Postural Assessment Scale for Stroke, and Trunk Impairment Scale. Results : Static balance showed statistically significant difference in foot pressure (p<.05) as a result of comparison between pre and post exercise training. Dynamic balance was statistically significant (p>.05) as a result of comparing pre and post differences using modified functional reach test. The trunk control ability was statistically significant (p>.001). Comparison between the results of before and after motion observation training showed a statistically significant difference. Conclusion: This study confirmed that exercise training in sitting position was effective for static, dynamic balance ability and trunk control ability of hemiplegic patients due to stroke. These results suggest that the use of motion monitoring in stroke patients may have a positive impact on the diversity and function of rehabilitation.
