We explore the issues on online political participation study in Korea compared with international one. More specifically, we characterize Korea's study trends as focusing on "who" is participating while international studies center on what the new "forms" of online political participation are. In other words, domestic studies try to show that online media play a role as a factor promoting bottom-up model of civic participation. Moreover, this function of online media is stimulated by the rapid growing of civic participation during democratization and citizens' deep disapproval of political institutions since then. However, previous studies are more interested in the expansion of participants, in particular, ordinary people. Therefore, the themes on conceptualizing and categorizing the online political participation seem to have been treated lightly. In this perspective, we need to view online political participation in a more multidimensional manner. In addition, we should pay attention to "those who do not participate" as well as "those who participate" in politics. Because the current media environment more tends to provoke citizens' political indifference than ever before. If it comes to that, we will be likely to face the circumstances worrying the democratic divide beyond the digital divide.

Recently, increasing use of big data have caused regulation factors of personal information and combination of pseudonymized information to emerge as key policy measures. Therefore, this study empirically analyzed the mediating effect and moderating effect of pseudonymized information combination as the third variable in the relationship between regulation factors of personal information and big data utilization. The analysis showed the following results: First, among personal information regulation factors, definition regulation, consent regulation, supervisory authority regulation, and punishment intensity regulation showed a positive(+) relationship with the big data utilization, while among pseudonymized information combination factors, non-identification of combination, standardization of combined pseudonymized information, and responsibility of combination were also found to be in a positive relationship with the use of big data. Second, among the factors of pseudonymized information combination, non-identification of combination, standardization of combined pseudonymized information, and responsibility of combination showed a positive(+) mediating effect in relation to regulation factors of personal information and big data utilization. Third, in the relationship between personal information regulation factors and big data utilization, the moderating effect hypothesis that each combination institution type of pseudonymized information (free-type, intermediary-type, and designated-type) would play a different role as a moderator was rejected. Based on the results of the empirical research, policy alternatives of 'Good Regulation' were proposed, which would maintain balance between protection of personal information and big data utilization.

It is apparently clear that K-pop has been expanding its influence overseas, with its high growth rate. As a result, attempts have been made to analyze the characteristics of K-Pop in various academic fields. This research quantitatively used the participatory use process of K-Pop contents in voluntary participation and dissemination of the audience in the Trans-Media environment. The author examined the use of participatory K-Pop contents from the view point of reparability through big data content analysis. It has been revealed that K-Pop is spreading globally through social media, fans of various countries like to play K-Pop, and they make up their own content and form a participatory culture. In addition, we looked at when the moments of momentum in which participatory use is soaring were popular content and who was the publisher.

The research and development in soundproof materials for preventing noise have attracted great attention due to their social impact. Noise insulation materials are especially important in the field of soundproofing. Since the insulation ability of most materials follows a mass rule, the heavy weight materials like concrete, lead and steel board are mainly used in the current noise insulation materials. To overcome some weak points in these materials, fiber reinforced composite materials with lightweight and other high performance characteristics are now being used. In this paper, innovative insulation sheet materials with carbon and/or glass fabrics and nano-silica hybrid PU resin are developed. The parameters related to sound performance, such as materials and fabric texture in base fabric, hybrid method of resin, size of silica particle and so on, are investigated. At the same time, the wave analysis code (PZFlex) is used to simulate some of experimental results. As a result, it is found that both bundle density and fabric texture in the base fabrics play an important role on the soundproof performance. Compared with the effect of base fabrics, the transmission loss in sheet materials increased more than 10 dB even though the thickness of the sample was only about 0.7 mm. The results show different values of transmission loss factor when the diameters of silica particles in coating materials changed. It is understood that the effect of the soundproof performance is different due to the change of hybrid method and the size of silica particles. Fillers occupying appropriate positions and with optimum size may achieve a better effect in soundproof performance. The effect of the particle content on the soundproof performance is confirmed, but there is a limit for the addition of the fillers. The optimization of silica content for the improvement of the sound insulation effect is important. It is observed that nano-particles will have better effect on the high soundproof performance. The sound insulation effect has been understood through a comparison between the experimental and analytical results. It is confirmed that the time-domain finite wave analysis (PZFlex) is effective for the prediction and design of soundproof performance materials. Both experimental and analytical results indicate that the developed materials have advantages in lightweight, flexibility, other mechanical properties and excellent soundproof performance.

The domestic game industry has constantly developed in a short time by concentrating on online games, and keeps growing as a highly added value industry. Also, in the social aspect, it has been seeking various alternatives to place online games as positive and new play culture in the digital era by avoiding negative criticism on game addictiveness. One of important factors in expanding the infrastructure of the game industry and developing it as a type of culture is not simply to develop the existing core genres (on the basis of profits), but to promote the approach of mixture with various contents and of positive functions and thereby enlarge users through various game genres. That is, it is to design games with positive themes and easy immersion by targeting a variety of game users. Such expansion of game design approach is a starting point to develop the infrastructure of the game industry. In the aspect, training professional human resources on the basis of academic and educational process is of significance. Therefore, this work was intended to suggest examples of design approach education based on creativity subject among various subjects with positive functions, and then propose an education process to which Capstone design education contents were applied.

Seoul has 424 traffic fatalities in 2010 and 227 of them related to pedestrian crashes. In addition, it revealed that 40% of pedestrian fatalities occurred during jaywalking. Through the effective methods preventing jaywalking can save lots of people, and it can reduce social costs pertinent to pedestrian crashes. Therefore, this study is to suggest the methods preventing jaywalking through conducting literature reviews, human factors with pedestrian and vehicle characteristics, as well as geometric features of accident site or spot. Firstly, in order for examining the contributing factors of accident, this research conducts statistical analysis on pedestrian accidents specifically in jaywalking. Secondly, the analysis on human factors about pedestrian and drivers revealed that drivers with high speed play pivotal roles in pedestrian fatalities. Thirdly, Road and environment factors showed both expected and contradictory results through analyzing total numbers of lane or dry/icy pavement conditions. Consequently, this study can be used to prevent and alleviate pedestrian accidents as well as expected to be applied to future researches about pedestrian safety facilities.

`Youthism` is pushing the youth research field into a trap of binarism fallacy. It tends to divide the whole population into the young and the old, and further gives an acceleration toward moving the division into the discursive realm of generation gap. The discursive transference is not taking place without any reasonable grounds. The series of discourse is based on two significant phenomena: changes in media background and longer schooling than ever before. Media environment overriding youth culture binds the young in a group and makes them enjoy homogeneous cultural genres. And schooling also seems to play an important role for the youth to have same cultural menus regardless of region, social strata, cultural background. But we need to recognize that after getting into the adulthood, they are not existing in the form of alliance. The youth are not in a homogeneous group. Neither are their culture. The youth are consisted of a variety of groups along such variables as gender, class of their parents. They tend to make distinction not only from the older generation but from the other peer groups. Unless avoiding the trap of youthism, we are blamed for closing eyes to the youth's desire to be distinctive among themselves. Youthism seems to be an active myth even in our academic society.

Unlike the era of manufacturing-oriented industrial economy in the past, the era of service economy has characteristics intangible goods center, knowledge universalization, and expansion of needs, and many things that are of the economy are changing. In the past, the change in the environment was not fast, so even after analyzing the changed environment and deriving the talent needed for the company, it was possible to maintain a talent for the organization for a long time, so it is not proactive to build and apply talent. It became difficult to manage effectively. Therefore, in this paper, we conducted a normative study for deriving a desirable talent model rather than a descriptive human resource model. Human resources image suitable for the modern service economy era, the modern economic society and modern spirit were analyzed and reflected. The model in which the two opposing members of the organization, managers and employees, interact intensely and balance dialectically. A desirable talent in a modern organization must play the role of a manager, and the management and talent models in a modern organization can be said to be connected to each other like the front and back sides of a coin. The philosophy of human resources was presented in five dimensions: human, historical, social, economic, and management. The human resource model from eight factors: mastery, rationality, wisdom, customer orientation, innovation, flexibility, autonomy, collaboration. This study suggested that general talent model may vary depending on the company's type, empirical follow-up studies are needed the talents in each company in the future.

Cytokines released from innate immune cells play key roles in the regulation of the immune response. Red Ginseng (RG, steamed and dried root of Panax ginseng C.A. Meyer) is known to show different pharmacological effects by changed composition of saponins compared with Panax Ginseng. In this study, we examined the immunomodulatory effects of RG on the regulation of cytokine release in mice. RG was injected i.p at doses of 0.5, 5 and 50 mg/kg for 6 weeks. We assessed that the weight index of immune organs such as thymus, and spleen, and the mitogen blastogenesis of splenocytes. We also determined the levels of circulating cytokines in serum from RG-treated mice using ELISA assay. The weight index of thymus and spleen, and proliferation of mitogen response of splenocytes have increased in the RG-injected groups. In addition, the levels of IFN-${\gamma}$, TNF-${\alpha}$, IL-6, IL-12 and IL-2 concentrations have significantly increased in the serum of RG-treated mice, but that of IL-10 has not. These results suggest that RG has immune stimulating effects and could be useful as a immunoregulator of circulating cytokine release in vivo.
