Up until about ten years ago, the use of typography played only an auxiliary role on broadcast television programs, primarily by transmitting information in order to facilitate a basic understanding of content. Recently, however, kinetic typography has become an important component in broadcast production. In fact, kinetic typography has developed into a visual language and a means of artistic expression, one that is increasingly used in the production of entertainment programs on television. This paper analyzes six aspects of kinetic typography: manner of development, location, intent, expressive techniques, color and font selection. Particular attention is placed on their use in three highly rated television entertainment programs: "2 Days & 1 Night", "Running Man", and "Infinite Challenge". The development way consists of the technique : starts off with cut and ends with cut. While, other techniques show conversation and situation representation using Z axis : zoom-in, zoom-out in , X axis : pan in <2 Days & 1 Night>. and Y axis : tilt in . Typographic design elements, expression technique, color, font are shown up according to the feature of each program. The resulting analysis suggests new ways for motion arts designers and the broadcast media to use kinetic typography in the development of television programs.

DSM and orthoimage, which are representative results of UAV photogrammetry, are high-quality spatial information data and are widely used in various fields of spatial information industry in recent years. However, the UAV photogrammetry has a problem that the quality of the output of the UAV deteriorates due to the altitude of the UAV, the camera calibration, the weather conditions at the time of shooting, the performance of the GPS / IMU and the number of the ground reference points. The purpose of this study is to analyze the location accuracy of unmanned aerial photogrammetry according to the change of the number if ground control points. Experiments were made with fixed wing, and the shooting altitude was set at 130m and 260m. The number of ground reference points used was 9, 8, 5, and 4, respectively. Ten checkpoints were used. XY RMSE for orthoimage and Z RMSE for DSM were compared and analyzed. In addition, the resolution of the orthoimage was determined to affect the judgment of the operator in the verification of the planimetric position accuracy, and the visual resolution was analyzed using the Siemens star target. As a result of the analysis, the variation of the vertical position accuracy is larger than the variation of the planimetric position accuracy when the number of the ground reference points are different. Also The higher the flying height, the greater the effect of change of ground control points on position accuracy.

Cutaneous stimulation and distraction are independent nursing interventions used in various painful conditions, which is explained by gate control theory. This study was aimed at identifying the effect of cutaneous stimulation, distraction and combination of cutaneous stimulation and distraction on the reduction of intravenous injection pain levels of chemotherapy patients. Repeated measurement post test research design was used for one group. Fifty-three cancer patients who received intravenous chemotherapy regulary in outpatient injection rooms of D medical center and Y medical center in Taegu were studied from June 23, 1997 to July 12, 1997. First the intravenous injection pain level of the control period was measured. Second, the intravenous injection pain level of the experimental period using cutaneous stimulation was measured. Third, the intravenous injection pain level of the experimental period using distraction was messured. Fourth, the intravenous injection pain level of the experimental period using a combination of cutaneous stimulation and distraction was measured. The instruments used for this study were a visual analogue pain scale as subjective pain measurement and an objective pain behavior checklist. Analysis of data was done by use of repeated measure ANOVA, bonferni, t-test, and F-test. The results of this study were summerized as follows : 1) The first hypothesis that the subjective pain score of intraveneous injection pain in the experimental period with cutaneous stimulation will be lower than in the control period was rejected. 2) The second hypothesis that the objective pain behavior score of intravenous injection pain in the experimental period with cutaneous stimulation will be lower than in the control period was accepted(F=24.23, p=0.0001, Bornferni p<.05). 3) The third hypothesis that the subjective pain score of intraveneous injection pain in the experimental period with distraction will be lower than in the control period was rejected. 4) The fourth hypothesis that the objective pain score of intravenous injection pain in the experimental period with distraction will be lower than in the control period was accepted(F=24.23, p=0.0001, Bornferni p<.05). 5) The fifth hypothesis that the subjective pain score of intravenous injection pain in the experimental period with combination of cutaneous stimulation and distraction will be lower than in the control period was accepted(F=3.04, p=0.031, Bonferni p<.05). 6) The sixth hypothesis that the objective pain score of intravenous injection pain in the experimental period with combination of cutaneous stimulation and distraction will be lower than in the control period was accepted(F=24.23, p=0.0001, Bonferni p<.05).

The main purpose of this study was to identify the effects of group social support and individual social support on the reduction of burden and improvement in family functioning of families with asthmatic children. The design of this study was a randomized pre-posttest quasi-experimental design to compare the two experimental groups. The theoretical framework for this study was derived from the study of burden in family caregivers by Suh and Oh (1993) based on the main effect model of social support theories. The data were collected from February 12, 1998 to May 29, 1998 at the pediatric out patient department of a university hospital located in Suwon city. The sample consisted of 39 family members who were identified as families with asthmatic children, Eighteen subjects were randomly assigned to the group social support group and 21 were assigned to the individual social support group. Group and individual social support members were seen for 60 to 90 minutes, four times over one to three weeks. The instruments used in this study were the Burden Scale developed by Suh & Oh(1993), the Visual Analogue Scale, and the Family Adaptability Cohesion Evaluation Scale(FACES-III) developed by Olson, Portner, and Lavee(1985). The collected data were analyzed using Mann-Whitney test, x$^2$-test, Wilcoxon sign rank test, t-test, ANOVA (Scheff), Pearson correlation coefficient. multiple regression, and social support process and content analysis. The results are as follow : 1. There was no significant difference before the experimental treatment among the subjects in the group social support group and individual social support group for general characteristics, burden, or family functioning. 2. Hypothesis 1 : “There will be a greater reduction on the burden score of the group social support group compared to the individual social support group” was not statistically significant(U＝174.5, p＝.683). The burden scores showed a significant decrease after participation in social support as compared to before participation for both groups. However there was a tendency for more reduction in the burden scores for the group social support than for individual social support. 3. Hypothesis 2 : “There will be a greater improvement in the family functioning scores for the group social support group compared to the individual social support group” was not statistically significant(U＝153.0. p＝.309). There was a tendency toward improvement in the family functioning scores of the group social support as compared to that of the individual social support. 4. According to the length of the treatment period, families with asthmatic children displayed affirmative responses, and the families set up a self-help group of mothers with asthmatic children in order to share their experiences, to get information and to solve their problems. In conclusion, it was found that group social support was the more effective nursing intervention for reducing burden and for improving family functioning of families with asthmatic children.

The need for customized products has also been increasing as more active consumers consume according to their values in recent years. Accordingly, fashion customizing web is becoming popular, but because custom freedom is low, we want to increase custom freedom by applying knitwear. To this end, a theoretical review was conducted through prior research and literature research on customization, knit design, and GUI, and based on this, a case analysis was conducted focusing on knit-making programs and fashion customizing web. Knit designs have more considerations than other fashion design process, resulting in more UIs, so users should use visual elements that are easily recognizable. Therefore, a draft assessment item was derived based on the preceding survey and three Delphi surveys were conducted on experts based on the draft. Each item was modified and deleted during the Delphi research process to produce the Custom Knitware Web GUI Design Guide. Through this study, we were able to identify the need for intuitive understanding and application of knit custom functions in GUI design of custom knitwear web. Through this research, it is expected that this data will be used to improve the usability of custom knitwear websites and to refer to knit design fields that utilize knit machines.

The soil prediction can provide quantitative soil information for sustainable mountainous ecosystem management. Visible near infrared spectroscopy, one of soil prediction methods, has been applied to predict several soil properties with effective costs, rapid and nondesctructive analysis, and satisfactory accuracy. Spectral preprocessing is a essential procedure to correct noisy spectra for visible near infrared spectroscopy. However, there are no attempts to evaluate various spectral preprocessing methods. We tested 5 different pretreatments, namely continuum removal, Savitzky-Golay filter, discrete wavelet transform, 1st derivative, and 2nd derivative to predict soil carbon(C) and nitrogen(N). Partial least squares regression was used for the prediction method. The total of 153 soil samples was split into 122 samples for calibration and 31 samples for validation. In the all range, absorption was increased with increasing C contents. Specifically, the visible region (650nm and 700nm) showed high values of the correlation coefficient with soil C and N contents. For spectral preprocessing methods, continuum removal had the highest prediction accuracy(Root Mean Square Error) for C(9.53mg/g) and N(0.79mg/g). Therefore, continuum removal was selected as the best preprocessing method. Additionally, there were no distinct differences between Savitzky-Golay filter and discrete wavelet transform for visual assessment and the methods showed similar validation results. According to the results, we also recommended Savitzky-Golay filter that is a simple pre-treatment with continuum removal.

Depth map upsampling is an approach to increase the spatial resolution of depth maps obtained from a depth camera. Depth map quality is closely related to 3D perception of stereoscopic image, multi-view image and holography. In general, the performance of upsampled depth map is evaluated by PSNR (Peak Signal to Noise Ratio). On the other hand, time-consuming 3D subjective tests requiring human subjects are carried out for examining the 3D perception as well as visual fatigue for 3D contents. Therefore, if an objective metric is closely correlated with a subjective test, the latter can be replaced by the objective metric. For this, this paper proposes a best metric by investigating the relationship between diverse objective metrics and 3D subjective tests. Diverse reference and no-reference metrics are adopted to evaluate the performance of upsampled depth maps. The subjective test is performed based on DSCQS test. From the utilization and analysis of three kinds of correlations, we validated that SSIM and Edge-PSNR can replace the subjective test.

The purpose of this study was to identify the factors influencing health promoting behavior of college students to develop health promoting interventions of young adults. The subjects of this study were 176 women college students, living in a small city in Korea. The data were collected by interviews and a self-report questionnaire, during the period from September, 1999 to December, 1999. The instruments for this study were the PRQ-II by Weinert(1988), the scale of Locus of Control by Wallstone et al.(1978), the scale of self efficacy by Sherer & Maddux(1982), 10 points visual analogue scale for perceived health status and the importance of health, the health promoting behavior scale by Walker et al.(1987), and the scales developed by the authors for the perceived benefits of health promoting behavior, and perceived barriers to health promoting behavior. Cronbach 's alpha of these scales were .68 ~.89. The data were analyzed using descriptive statistics, Pearson's correlation coefficients, and stepwise multiple regression. The results of this study were as follows: 1. Among cognitive perceptual factors of the Health Promotion Model by Pender(1987), the scores of the importance of health, the perceived internal control of health, self efficacy, the perceived health status, and the perceived benefits had a significantly positive correlation with the scores of the health promoting behavior of college students. In addition, the scores of the perceived barriers had a significantly negative correlation with the scores of the health promoting behavior of college students. 2. Among modifying factors of the Health Promotion Model by Pender(1987), the extent of religious activities of college students and the scores of social support had a significantly positive correlation with the scores of health promoting behavior of college students. 3. Stepwise multiple regression analysis revealed that the most powerful predictor of health promoting behavior was self-efficacy. A combination of self-efficacy, the perceived benefits, the perceived barriers, the perceived health status, and the importance of health accounted for 45.1% of the variance in health promoting behavior in college students From the results of this study, we concluded that the Health Promotion Model by Pender can be used to explain health promoting behavior of college students. In addition, we suggested that the results of this study be considered in developing health promoting programs of young adults.
