This paper proposes a new JPEG format, All-in-JPEG, which can include not only multiple photos but also various media such as audio and text by extending the JPEG format. All-in-JPEG add images, audio, and text at the existing JPEG file, and stores meta information by utilizing the APP3 segment of JPEG. With All-in-JPEG, smartphone users can save many pictures taken in burst shots in one file, and it is also very convenient to share them with others. In addition, you can create a live photo, such as saving a short audio at the time of taking a photo or moving a part of the photo. In addition, it can be used for various applications such as a photo diary app that stores images, voices, and diary text in a single All-in-JPEG file. In this paper, we developed an app that creates and edits All-in-JPEG, a photo diary app, and a magic photo function, and verified feasibility of the All-in-JPEG through them.
The purpose of this study was to analyze the questions of earth science knowledge presented in elementary science textbooks. In group activities, The questions were created by preservice elementary teachers assuming that they were teaching the earth science knowledge in science education classes at university of education. Types, frequencies, and sources of the cognitive background knowledge of the questions were analyzed. The results demonstrated the followings. First, types, concentrations, and sources of the cognitive background knowledge of the questions were different depending on the domains of earth science. Specifically, in astronomy domain, the frequencies and concentrations of the questions showed different trends compared with other domains in its individual lessons. It suggests that instructional strategies that reflected the difference found in each lessons be appropriately designed and used. Second, it was found that 'schools' was the most dominant sources of the cognitive background. 'Friends' were also found to be very important sources, thus promoting students' interaction with their peers would become an important strategy in science teaching. It was also found that mass media such as 'internet' and 'TV' were roughly rated the same as 'schools' which illustrated that mass media could be utilized in science instruction. Third, since types, concentrations, and frequencies of the questions were diverse in the lessons of units, it is suggested that diverse instruction strategies also be taken into account as an educational approach in teaching the subjects in teacher education.
A work of Art is not supposed to be isolated from the world, but it should be influenced by its cultural background and situations of the times. Therefore, Art itself reflects its era. In other words, it is created being based on the thought of its artist and simultaneously interacting with external conditions or circumstances of the era, so it would also affect the cultural code of its society. This is why modern art made by the individual living in this complicated and diversified society is quite avant-garde. Various demands from its society and diversified senses have been influencing diversification of works of Art. Now we can say that a mode of art is also dose to current stream of the times. A lot of artists have been trying to get out of traditional way of presentation techniques and classification of genres. In that point, the emergence of Multimedia Alt is inevitable in this digital era. The terms of Internet or multimedia are now familiar with everybody in the world, and a lot of works like Technology Art, Information Art, Computer Art, Digital Art, New Media Art, and so on have been coming into the world by using multimedia. Unlike other works of Art, these works from multimedia are practically used by being combined with technologies. Hereupon, in this paper I would like to find out a concept of Multimedia Art, its social function, and the future prospect of this brand-new form of art.

In the modern society, instructional methods using diverse media have appeared thanks to the development of Information & Communication Technology, and applicability of such instructional methods has been fully corroborated. However, customized contents allowing for disabled children's environment are still insufficient. Hence, this study produced educational contents of play activities for children with developmental disability, through applying N-screen technology, IT technology that can provide the same contents via a variety of digital media. The produced contents allow programs to be set up according to a child's individual characteristics and be carried out anywhere and anytime via an Internet-enabled digital device. Further, the developed contents were produced so that they could be accessed from a child's various environment (home, school, etc.) via a PC, a smart phone, a portable from a child's various environment (home, school, etc.) via a PC, a smart phone, a portable device, etc. and that the same educational program could be conducted in linkage at home, school, etc. Three children with Intellectual disability and autism spectrum disorder were applied to the manufactured content. As a result, Content interaction between interaction between teachers and students in play training could use as a medium.In addition, the children's ability to select the appropriate components and reinforcements, special education professionals have used the content of the interviews are helpful in mediation than the existing content.
Mosts user of internet and smart phone has certificate, and uses it when money transfer, stock trading, on-line shopping, etc. Mosts user stores certificate in a hard disk drive of PC, or the external storage medium. In particular, the certification agencies are encouraged for user to store certificate in external storage media such as USB memory rather than a hard disk drive. User think that the external storage medium is safe, but when it is connect to a PC, certificate may be copied easily, and can be exposed to hackers through malware or pharming site. Moreover, if a hacker knows the user's password, he can use user's certificate without restrictions. In this paper, we suggest secure management scheme of the private key file using a password of the encrypted private key file, and a USB Memory's hardware information. The private key file is protected safely even if the encrypted private key file is copied or exposed by a hacker. Also, if the password of the private key file is exposed, USB Memory's container ID, additional authentication factor keeps the private key file safe. Therefore, suggested scheme can improve the security of the external storage media for certificate.

This study was attempted to find out the actual conditions about drug education among the elementary school teachers. Subjects consisted of nurse-teachers 175, class-room teachers 240 and athletics teachers 53 at the elementary schools in Pusan city. The data collecting period was December 23th through December 28th, 2002 and the collected data were analyzed by SPSSWIN 10.0 program using frequency, percentage, mean, standard deviation and $x^2$-test. The results of this study were as follows: 1. The importance of the drug education in special curriculum has been agreed with 96.0% of nurse-teachers, 90.4% of classroom teachers and 92.4% of athletics teachers. 2. For the drug education, nurse-teachers used to get information through the professional knowledge books(61.1%), and internet (33.1%), on the other hand class-room teachers(80.0%) and athletics teachers (48.9%) used to get information from various media. 3. Until now, the drug education has been performed by 80.6% of nurse-teachers, 34.2% of class-room teachers and 41.5% of athletics teachers. After drug education, the results of self-evaluation showed that 73.8% of nurse-teachers and 51.9% of athletics teachers were satisfied with it, but 69.5% of class-room teachers were not. In terms of the education methodology, most nurse-teachers(85.8%) usually used both verbal lecture and multi-media materials for teaching, but class-room teachers(97.8%) and athletics teachers(81.8%) just gave the verbal lecture. 4.

Recently, the research relative to NGN(Next Generation Network) is progressing in 3GPP(The 3rd Generation Partnership Progect), IETF(Internet Engineering Task Force), and so on. Although user needs frequently mobility which is various service pattern, In accordance with the development of these various applications, IMS(IP Multimedia Subsystem) and hierarchical networks ie, Femtocell/WiBro/3G etc is constructed for more user demands which provide service in anytime, anywhere. It is necessary to optimum network selection criterion which consider to wireless signal quality add to user service profile and service network traffic balance. NGN also needs a method to perform heterogeneous handover and to constraint Ping-pong phenomenon when using existing terminal-based handover decision. This paper proposes scheme for network selection and heterogeneous handover procedure in hierarchical wireless multi-access network based on SIP-MIH(Session Initiation Protocol-Media Independent Handover) with IMS by using user service profile that the considerations are dealing with not only selection and registration of various access network but also easy of developing the terminal.

According to the Ministry of Health and Welfare, "Status of Registered Persons with Disabilities", the number of people with disabilities is 2,494,460 as of 2015. The lowest rates of children with disabilities were intellectual disabilities (23%) and mental disorders (33.3%). The highest rates of screening were blindness (97%), heart failure (94.4%), and hearing impairment (92.7%). 65.2% of visually impaired people who have already had a disability at the time of marriage, and the remaining 34.8% can be thought to be the cause of high incidence of disability after marriage. 'SID (Seed in the Dark)' project was designed to recapture the visually impaired parent's desire for attachment and the space difficulties of the blind who want to be a normal parent to their children through a visual impairment of a father with 7-year-old daughter. Using Gear VR(Virtual Reality), the general public was able to feel the surroundings as if they had no vision and focused on the hearing. Especially, We expressed the sound wave visually and added the hilarious game element which grasps the terrain of the maze by sound wave like a 'blind person who perceives the surroundings by sound' and catches up with daughter. People with disabilities who are far from mental illness often have a form of family with children. The fact that the rate of childbirth is high means that there is relatively little problem in daily life. It is wondered that the rate of blindness among the visually impaired, which accounts for 10% of the total disabled, is the highest at 97%. This is because, in the case of the visually impaired, the obstacle is often caused by aging, accidents, or diseases due to inherited causes rather than the visual disorder. In particular, However, the fact that there is an obstacle in vision that accounts for 83% of the body's sensory organs causes other difficulties in the nursing process of children who are non-disabled. Parents do not know the face of child when their visual impairment is severe. Parents are extremely anxious about worry that they will be lost or abducted if their children are not by their side. And that the child recognizes the disability of his or her parents other than the other parents easily and takes it as a deficiency. Since visually impaired parents are mentally mature parents with non-disabled people, they may want their children not to feel deprived of their disability. The number of people with visual impairments has been increasing since 2001, and people with impairments often become disabled. In addition, there is much research on the problem of nondisabled parents who have children with disabilities, while there is relatively little interest and research on the problem of nondisabled child rearing of parents with disabilities.

In this paper, we propose an effective method to block illegal gambling advertisement on social media. With the increase of smartphone and internet usage, users can easily access various information while sharing information such as text and video with a large number of others. In addition, illegal sports gambling advertisements are also continue to be transmitted on SNS. To avoid most surveillance networks, users are easily exposed to illegal sports gambling advertisement images by including phrases in the images that indicate illegal sports gambling advertisements. In order to cope with these problems, we proposed a method to actively block illegal sports gambling advertisements in a way different from the conventional passive methods. In this paper, we select words frequently used for illegal sports gambling, classifies them into three groups according to their importance, calculate WF for each word using weighted formula by degree of relevance and frequency, and then sum the WF of the words in the image. Blocking, warning, and passing were determined by cv, the total of WF. Experimenting with the proposed method, 193 out of 200 experimental images were correctly judged with 96.5% accuracy, and even though 7 images were illegal sports gambling advertisements. Further research is needed to block 3.5% of illegal sports betting ads that cannot be blocked in the future.
