This article attempts to explain social media use within the relationship between the public and government of Indonesia in the era of digital government, as well as to consider public opinion on this matter. This research is based on the application of social media logic and the theory of dialogic communication and action. A qualitative descriptive approach was used to observe the general behavior of social media use by 34 ministries in Indonesia, including interviews with the resource persons within the ministries and focus group discussions with members of the public and observers. The research shows that the relationship between the public and government is accommodative and in line with social media logic. The public sector implemented social media as its platform, which has been further adopted by all ministries. The public sector cannot avoid social media, as it has become part of basic connectivity, even though the use of social media by the government still tends to be in the form of presenting public information. There are advantages and disadvantages of the usage of social media by the government. The advantages include allowing the government to be more open via social media so that communication between the government as the ruling organization and its public can be more fluent. Social media provides space to the public sector in the practice of digital government. Some disadvantages arise as logical consequences that usage of social media cannot be separated from the implementation of digital government. The adaptive behavior of social media by the government can be found by following social media logic as part of digital government implementation. Social media logic causes the government to follow the rules of social media. In this context, the strength and power of the country seems to be regulated by social media. Therefore, more studies on how social media is managed in the context of its usage as digital government support is needed.

The purpose of this study was to investigate the influences of environmental education program through various instructional media on pro-environmental attitudes of forth graders in an elementary school in Seoul. The students were divided into an experimental group and a control group. A questionnaire was used to survey the effects of applying environmental education program through various instructional media. The SPSS 12.0 program was used to analyze the results. The student in the experimental group acquired a higher level of pro-environmental attitudes than the control group did. The environmental education program through various instructional media used in this study were effective especially in dealing with the environmental educational subdomains such as verbal commitment, actual commitment, affect. The major results of this study were as follows. First, environmental education program through various instructional media had a positive effect on the environmental concerns and needs for learning of environmental problems. Second, the group by environmental education program through various instructional media showed the significant difference(p<.001) on the pro-environmental attitudes as it proved those are effect on 3 subdomains of verbal commitment, actual commitment and affect. Third, environmental education program through various instructional media had a positive correlation(from 585 to .680) among the 3 subdomains of verbal commitment, actual commitment and affect. So, students who hold verbal commitment showed good effect on the actual commitment and affect. In conclusion, the environmental education program through various instructional media had a positive effect on pro-environmental attitudes of elementary school students. It is demanded that more intensive research on this study should be done, linking with teaching and teaming method, as a follow-up activity.

Background: Defective or immature antibody responses to pathogens in children may explain the increased susceptibility to acute otitis media. However, there is no study in Korea patients whether a correlation exists between otitis media with effusion and the levels of serum immunoglobulins, IgG subclasses, IgA, IgM and IgE. Methods: 45 children with otitis media with effusion more than 4 episodes in 12 months or 3 episodes in 6 months, 62 children with otitis media with effusion less than 3 episodes in 12 months and 102 children for control group took part in the study at the Department of Otorhinolaryngology of the KyungHee University from May 2004 to Feburary 2007. Serum immunoglobulin levels were determined by nephelometry. And then the relationship between otitis media with effusion and serum immunoglobulin level was evaluated. Results: In otitis media prone group, serum IgG1, IgG2, IgG4, and IgA level was lower than those level of control group, it was significantly decreased (p<0.05). In otitis media group, serum IgA, IgE, and IgG4 level was lower than those level of control. But it was not statistically significant (p>0.05). Conclusion: Lower immunoglobulins in children with otitis media with effusion suggest a generalized decreased antibody responses. Lower levels of serum IgG1, IgG2, IgG4, and IgA may be related with chronicity or intractability of otitis media with effusion.

This paper describes issues and consideration on authoring of interactive multi-view visual content based on MPEG-4. The issues include types of multi-view visual content; scene composition for rendering; functionalities for user-interaction; and multi-view visual content file format. The MPEG-4 standard, which aims to provide an object based audiovisual coding tool, has been developed to address the emerging needs from communications, interactive broadcasting as well as from mixed service models resulting from technological convergence. Due to the feature of object based coding, the use of MPEG-4 can resolve the format diversity problem of multi-view visual contents while providing high interactivity to users. Throughout this paper, we will present which issues need to be determined and how they can be realized by means of MPEG-4 Systems.

Objective: The increasing use of imaging examinations such as computed tomography (CT) results in increased contrast media use, which increases contrast media-induced adverse reactions (AR). This study investigated the risk factors of ARs to nonionic iodinated contrast media. Methods: This study evaluated patients who were administered iodinated contrast media during CT scanning in Yeouido St. Mary's Hospital in Seoul, Korea in 2012. Among the subjects, those with contrast media-induced ARs were classified as the AR group. The control group included individuals without ARs who were selected through simple random sampling. The effects of sex, age, contrast media type and dose, CT region, previous contrast media administration, allergy history, and comorbidity were analyzed in the AR and control groups. Results: Multivariate logistic regression analyses were performed to evaluate the identified AR risk factors in 103 subjects in the AR group and 412 subjects in the control group. The results confirmed that the risk of developing ARs was significantly higher in females [odds ratio (OR): 2.206; 95% confidence interval (CI): 1.353-3.598], in individuals administered Iohexol (OR: 9.981; 95% CI: 2.361-42.193), in individuals with an allergy history (OR: 3.982; 95% CI: 1.742-9.101), and in individuals with comorbid asthma (OR: 6.619; 95% CI: 1.377-31.826). Most of the ARs were mild and immediate. Conclusion: In patients who were administered contrast media during CT scans, female gender, Iohexol use, allergy history, and asthma were risk factors for ARs. Therefore, special care is required for patients with such risk factors to prevent ARs.

In this paper we propose an integrated media format for a photo album including media resources and corresponding meta-data The main purpose of the integrated media is to be more reusable meta-data and to facilitate constructing a photo album from a large number of photo images as well. The proposed media format is based on MAF(multimedia Application Format) which is recently going on progress in MPEG standards. In this paper, we propose the integrated media consisting of JPEG data and content-based meta-data based on MPEG-7 MDS. We verified the usefulness of the proposed media through experiments with implementation of encoder and photo MAF player for the MAF-based media format.
