Ecological predictors of imaginative playfulness were researched to test relationships among preschoolers' individual characteristics, socioeconomic status, their visual media use, and their imaginative playfulness. Data were collected from 202 primary caregivers and head teachers in childcare centers in Michigan, U. S. A. Use of visual media was coded by the program categorization of Anderson et al. (2001) and the Television and Movie Violence Rating Scale (Huesmann et al. 2003). Imaginative playfulness was rated by the adapted Playfulness Scale (Barnett 1990). Results of hierarchical regression showed that child characteristics of age and gender predictors contributed to their imaginative playfulness. On the other hand, children's visual media use and socioeconomic status of their families did not predict their imaginative playfulness.

현행 TV 브라운관용 panel의 투과검사 작업장에서의 조명설계에 대한 문제점을 규명한 결과, 투과검사 작업시 사용되지 않는 광원부분으로 인한 glare가 있음이 파악되었다. 본 연구에서는 glare가 직접적으로 visibility를 감소시키는지의 여부와 장시간 glare에 노출되어 누적된 눈의 피로가 결과적으로 작업에 영향을 미치는지를 알아보았다. 이를 위해 glare광원의 각도와 투과검사작업의 work period가 변화함에 따라 작업수행도가 어떻게 변화하는가를 정량적으로 관찰하였다. 연구결과, visibility에 직접적으로 영향을 미치지 않는 소량의 glare도 장시간 누적되면, 눈의 피로를 유발하여, 작업수행도에 영향을 미치며, 육안검사작업의 작업수행도 저하에 대한 indicator로서 DGR(discomfort glare rating)이 활용될 수 있음이 파악되었다. 또한, 작업특성에 관계없이 일률적으로 적용되는 VCP(visual comfort probabilities)를 기준으로 실제작업장의 조명을 설계하기는 어려울 것으로 판단된다.

This study content-analyzed Korean cable television programs aired from Feb. 6 to Feb. 19, 2007, focusing on the contextual variables linked to violent acts. A total of 657 PAT's (perpetrator-action-target) in the 68 programs sampled were analyzed for characters' age, sex, type, relationship, and motivation, humorization, punishment for their violent acts, and finally reality of violence. According to the results, (1) most violence occurred among male characters, who were at their ages between 20 and 39; (2) more than half of the total violent acts happened among acquaintances including family members; (3) anger, retaliation, personal or group interest, and violence for fun were ranked at the top tiers of the motivation list; (4) most violences were overlooked without punishment; (5) and about 80% of the whole violence were realistic. In terms of program types, (1) female perpetrator and victims appealed more often in drama than the other genres; (2) violence among acquaintances and simple fun as motivation were prevalent most in entertainment programs; (3) every violent act in children's programs was done by unrealistic characters. According to the analysis by program ratings, (1) while least violence appeared in '19 and older', all of the violent acts were portrayed as realistic; (2) humorization were most prevalent in the 'everyone' rating; (3) and female perpetrators and victims appealed most in the programs rated as '15 and older'. Generally, various contextualized violences displayed different distributions according to program types and ratings. The qualitative features of the current findings about cable television violence provide a fundamental data for future studies, which will explore the subsequent effects of violent media contents.

The purpose of this study was to evaluate the timing of precocious puberty and the factors inducing precocious puberty in elemental school girls students of low grades. The 1st, 2nd, and 3rd grade 253 elemental girls students from the Goryong province were randomly selected, G and D elemental school. sexual maturation rate was assessed physical examination by the parents. After obtaining an informed consent, a questionnaire was administered to the parents; sexual maturation rate was assessed by self physical examination, eating habits, lifestyle and home background were evaluated to determine the factors that induced precocious puberty. The data were statistically analyzed. We selected 253 girls: The total percentage of the precocious puberty was 26.1%. 7(7.8%) 6-year-old girls, 9 (13.2%) 7-year-old girls, 50 (52.6%) 8-year-old girls were in breast stage 2 and over. The main factors influencing precocious puberty were obesity scale, frequency of eating instant food, TV watching time, stress levels and broken family. A high rating on the obesity scale and high frequency of eating instant food, too much time in front of TV, high stress and broken family indicated advanced stage of puberty. This study show that prevalence ratio of the precocious puberty was 26.1%. The significant influencing factors in advanced puberty were obesity scale and frequency of instant food, TV watching time, high stress and broken family.

Virtual Advertising, which was introduced exclusively in sports casting programs in 2010, has enlarged its scope to terrestrial TV networks' sports news, entertainment shows, and dramas by 2015. Such advertising deregulation allows broadcasting business operators to insert more various virtual advertising methods into TV programs. Despite recent evaluation that virtual advertising was deregulated to a large degree, it is still inadequate compared to foreign state of affairs and has a lot of room for growth. Therefore, this research explores a literature review of virtual advertising in other countries and considers possible ways for virtual advertising in Korea to move forward. Additionally, through in-depth interview with seven virtual advertising experts, the research unravels positive and negative impacts of virtual advertising as well as its current state of affairs and struggles. This research also analyses the regulation of virtual advertising and finally explores possible revitalization strategies. The results of the research show that it is necessary to first improve the viewers' favorable concerning virtual advertising in order to revitalize virtual advertising. Revitalization will also require a clarification of regulation as well as a more unified and consistent content review and rating system. Furthermore, it is imperative that data of advertising impact will be accessible to advertisers and that advertising regulation will loosen. Revitalization will also require a clarification of regulation as well as a more unified and consistent content review and rating system. Furthermore, it is imperative that data of advertising impact will be accessible to advertisers and that advertising regulation will loosen. It is necessary to further develop new techniques and creators of virtual advertising.

Evaluation plays an essential role in design activity. Many theorist have agreed that designing involves problem solving or decision making. In evaluation, designers attempt to determine the value of a particular proposal arrived at by synthesis. And the results of designing, the product, is evaluated twice, objectively and subjectively.Alternatives in $$\mu$ti-objective decision problems generally possess numerous attributes by which they can be described and compared. The evaluation factors include all attributes that have levels specified by quantitative and qualitative objectives. However since qualitiative factors are difficult to quantify as $$\mu$eral estmates, these factors have tended to be ignored without regard for their importance to human content. Therefore we need some study that convert qualitative attributes into quantitative scale values. Following to Thurstone' s Psychological scaling methods (The method of successive intervals), attribute values of TV set are assigned by rating scale methods. The method of successive intervals, like the method of equal-appearing intervals, requires but a single judgement from each subject for each statement to be scaled. It is, therefore, a convinient method to use when the number of to be scaled is large. We make the assumtion that those cu$$\mu$ative proportion distributions are normal for each statement when they are projected on the unknown psychological continuum. In this study, we have determined the scale values of 42 statements of TV set by the method of successive intervals. Then we can apply a test of internal consistency similar to that used with the method of paired comparisons. We have as our absolute average deviation, -1.748/252= -0.0069. We have reason to believe that our scale values are consistent with the empirical data, because these discrepanicies are very small.

This study was to examine music preferences of school-aged cochlear implant(CI) recipients in comparison with normal hearing(NH) children. Participants were 12 CI recipients and 155 NH children. CI children were recruited from a hospital in Seoul and they had cochlear implants for longer than two years(M = 4.7). NH children were randomly sampled. All participants were asked to respond to a questionnaire and rate their music preferences. The results showed that while 58.33% of CI recipients preferred child voices, 71.61% of NH children preferred adult voices. For preferred frequency range, both of CI and NH groups preferred higher frequency. With regard to preferred musical styles, while CI children gave the highest rating(M = 3.58) to Korean folk songs on the 5-point Likert scale, popular music and TV and soundtrack music were found to be the highest-rated styles(M = 3.83) for NH children. These results indicate that self-rated music preferences of CI recipients may be affected by a musical environment that these children have experienced. The results also implies that the provision of appropriate musical input and experiences would significantly affect future music preferences and appreciation of CI children. Providing useful information about music preferences of CI recipients in comparison with NH children, this study has significant implications for further studies on this population.

EPG (Electronic Program Guide), which shows the title, broadcasting time, genre, parental rating of a program, is recognized as one of the most successful data service by viewers and broadcasting stations, who want an improved TV watching experience and a more fruitful profit model, respectively. In the circumstance, the request for the development or renewal of EPG frequently occurs and so the developers are looking for ways to improve the efficiency of the EPG development. This paper addresses the need of the developers by devising an EPG feature model based on FODA (Feature-Oriented Domain Analysis) and the testcases of each feature of the model. By utilizing the EPG feature model and the testcases, the tasks of requirement analysing and testcase designing, which are major tasks of the EPG development process, can be improved.
