The goal of this study was to analyze the demands of parents of an after-school program. In order to do this, we looked at cultural centers and their curriculums. Cultural centers are one of the most popular private education centers for preschoolers, and are used for the operation of special activities. The research was conducted on preschool curriculums of 300 cultural centers, including cultural centers of department stores and supermarkets. The curriculum analysis was conducted for 400 preschool curriculums of three cultural centers, which had the most programs of all. The scope of the curriculum analysis was based on the 3rd Childcare Standard Curriculum for infants and Nuri Curriculum for preschoolers. As a result of the analysis, there were 12,286 programs for infants. The most popular topics for programs were comprehensive activity, physical activity, and music activity. There were 15,310 programs for preschoolers. Physical activity was the most popular topic among them. It was followed by drawing activity and number and operating activity. Analyzing the contents of these programs, we found that 'participating in physical activity' of physical exercise, and 'expressing artistically' of artistic experience were the most popular contents of infants. 'Expressing artistically' of artistic experience and 'control of body and basic exercise' of physical exercise were most popular contents for preschoolers. The results show that parents demand physical activity programs for infants and artistic activity programs for preschoolers. The results of the research should be considered when childcare centers try to make a special after-school program.

With the rapid growth of the wireless Internet communication, a new generation of mobile devices have made possible the broad distribution of mobile digital contents, such as image, music, video, games and applications over the wireless Internet. Mobile devices are rapidly becoming the major means to extend communication channels without copy Protection, usage rule controlling and authentication. As a result, mobile digital contents may be illegally altered, copied and distributed among unauthorized mobile devices. In this paper, we take a look at Open Mobile Alliance (OMA) DRM v2.0 in general, its purpose and function. The OMA is uniquely the focal point for development of an open standard for mobile DRM. Next we introduces features for an active content and illustrates the difference between an active content and an inactive content. Enabling fast rendering of an active content, we propose an OMA-based DRM framework. This framework include the following: 1) Extending DCF Header for supporting an selective encryption, 2) Content encryption key management, 3) Rendering API for an active content. Experimental results show that the proposed framework is able to render an active content fast enough to satisfy Quality of Experience. %is framework has been proposed for a mobile device environment, but it is also applicable to other devices, such as portable media players, set-top boxes, or personal computer.

Since 2009, stars produced through audition programs have appeared through the process of establishing familiar ties with viewers, unlike stars created by entertainment agencies. This study is a case study that examines the characteristics, roles, and identity of internet live broadcasts (Labang) of vocalists Kang Dong-hoon and his fan cafe(fan community) who appeared in JTBC Phantom Singer 3 in 2020. As a result of the study, fans gathered around SNS even before the fan cafe was created, at their request, 'Labang' began. "Labang" is a "freely participating talk show" in which fans actively participate. This brought about the bond of fans, a sense of belonging, and the activation of fandom. Both stars and fans recognized "Live Broadcast" as "a window of communication to get to know each other," and expressed satisfaction that they could see the sincerity of familiar and unpretentious stars, not unrealistic images reproduced on TV through "immediate comment communication." "Labang" consists of a variety of contents, including stars' daily lives, music activities, broadcast appearances, and hobbies, and is showing "aesthetic differentiation" from those who do not watch "Labang" while sharing the daily lives of stars and fans with active participation.

This research evaluates the accessibility of the mobile applications for the South Korean libraries based on the accessibility guideline from the Ministry of Security and Public Administration. In order to enhance the credibility of the evaluation, this current research covers both the accessibility for the visually impaired and the accessibility for the people without disabilities. The research found four main results. First, we found that only 21 libraries (31%) provide alternative texts. Out of the 21 libraries, only one provide alternative texts across all sections of the mobile applications, including the main page, data search, information assistance, etc. Second, most of the mobile applications provide contents in texts, and the subtitles, sign language, blinking and background music provided as required or recommended standard by the guideline lack correlation. Third, alternative texts, focus movement, accessibility of operating system, button motion control, spacing between control and alarm functions must follow the standard guideline for the people with disabilities to use the mobile applications. Fourth, follow-up research on the development of accessibility standard for library mobile application is necessary in order to enable people with disabilities to freely use the library mobile applications.

Objectives : 'Taegyo,' prenatal education, is steeped into Korean culture. Although there has been a traditional focus on providing education and care for the fetus in Korea, there is a lack of medical evidence for its effectiveness. Methods : The authors assessed the scientific basis for 'Taegyo' by reviewing the evidences. Results : 'Taegyo' in Korea began with the spread of Buddhist culture from China, and transmitted by word-of-mouth. The first 'Taegyo' book, the Tae-gyo-shin-gi, was published on 1803. Modern prenatal education is very diverse. However, only a few studies on its effect have been conducted. Development of medicine, especially obstetrics, fetology, pediatrics, psychiatry, and etc., has learned that many factors, including bad environmental conditions and maternal stress, influenced against the fetus and mother. As for the paternal side, occupation, smoking, and stress were also revealed to have consequences for the development of the fetus. On the contrary, adequate maternal nutrition, exercise, and music stimulation positively impact the fetal development and healthy birth. Conclusion : Traditional contents of 'Taegyo' were proved to have effectiveness from evidence-based medicine and animal experiments. We need further studies to explore the impact of prenatal education for the fetal development and maternal health.

With widespread use of the Internet and improvements in streaming media and compression technology, digital music, video, and image can be distributed instantaneously across the Internet to end-users. However, most conventional Digital Right Management are often not secure and not fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. The SVC offers temporal, spatial, and SNR scalability to varying network bandwidth and different application needs. Meanwhile, for many multimedia services, security is an important component to restrict unauthorized content access and distribution. This suggests the need for new cryptography system implementations that can operate at SVC. In this paper, we propose a new scrambling encryption for reserving the characteristic of scalability in MPEG4-SVC. In the base layer, the proposed algorithm is applied and performed the selective scambling. And it encrypts various MVS and intra-mode scrambling in the enhancement layer. In the decryption, it decrypts each encrypted layers by using another encrypted keys. Throughout the experimental results, the proposed algorithms have low complexity in encryption and the robustness of communication errors.

Purpose: The purpose of this study is to explore mother's perception and practice of Taegyo. In addition, belief factors toward Taegyo oriented Korean mother-fetus interaction are identified in order to obtain baseline data for the development of Taegyo oriented program enhancing mother-fetus interaction. Method: The sample consisted to 186 pregnant women who visited public health center or hospital for prenatal care. Self-reporting questionnaire devised by investigator was used. Data were analyzed by SPSS win program and contents analysis was used. Result: Although mothers intended to a pregnancy, many of them were perceived negatively toward pregnancy. The study revealed that most of pregnant women continued cultural practices related to Taegyo, they focused on mother-fetus interaction behavior-such as listen to the music, reading a book, talk to fetus, stroke the fetus- with being altered traditional beliefs toward Taegyo or Taemong. Most of pregnant women had Taemong and believed a it's predictive functions. Beliefs toward mother-fetus interaction were classified to 6 factors, pregnancy, Taemong. fetus, practice behavior, infant's abilities and mother-fetus interaction behavior. The scores of belief toward mother-fetus interaction and each factors of pregnancy, fetus, practice behavior, infant's ability were statistically significant different depending upon husbands education. Also pregnancy factor in belief toward mother-fetus interaction was statistically significant different depending upon the number of children, child birth, experience of abortion, premature birth. Conclusion: Developing Taegyo oriented program enhancing the mother-fetus interaction need to include the elements of being facilitated maternal identity formation and maternal confidence for the pregnant women. In addition, it should be developed the program concerning with the characteristics of the pregnant women.

Concentration is one of the most important factor in learning ability. It is important to improve concentration for learning ability. Most digital kids have been accustomed to addictive media like games since childhood, so traditional methods of teaching and learning has been difficult to give interests for them. Therefore introducing a new teaching methods was inevitable for students with low concentration. This is an experiment to prove the hypothesis that the concentration training by certain serious game would be helpful for improving students' concentration. Not only some serious games but also meditation by music was effective to improve concentration in the experiment. Average people is hard to immerge in meditation. but some serious games involve fun factors like curiosity, challenges, competitions and rewards. Games are not more negative to young people, will be helpful to society in various forms.

The style of costumes which dancers put on for dancing on a stage reflects the times, culture, and traditionality of movements in dancing. Accordingly, everyday dresses are adopted as the stage costumes in some cases and stage costumes lead the trend in other cases. Furthermore, like stage costumes in other genres, dancing costumes put more emphasis on expressive features in the functions of clothing unlike everyday dresses. In particular, dancing costumes shall sufficiently and delicately express each movement using the costumes as well as rhythms and melodies of music for dance. Ballet which is the representative western dance was derived from the world "Ballare" meaning "dance" in Italian. As shown in the change of word, ballet started in Italy. In Italy taking initiatives for all artistic activities in Europe as leading Renaissance in the 15th century, ballet started as the court dance and favored by French. Then, ballet flourished in France and was developed to the Romantic ballet in the 19th century. During the Renaissance, the early stage of ballet development the dancers put on the dresses which were in fashion at that time on the stage. The dancing costumes added the decorative features suitable for the characteristics of main actors or actresses and contents of dances to the dresses in fashion at relevant times in 17th and 18th century. "Panier", the dancing costume in the 18th century, was sensationally popular among women. As described above, the study on the features of dancing costumes by times not only arranges the costumes in each times but also investigates emotions and artistic and aesthetic values of those who lived in the relevant times. Furthermore, it is the way to experience the height of fantasy and beauty.
