The study explores how the discourses on game addiction, which emphasize diligence and sincerity for labor and self-control, and professional gamers, who are trapped in pleasures of playing games in the virtual world, cohabit in Korean society. Progamers have grown from entertainment industry enlarged along with the current of the economic 'postmodernization,' mentioned by Hardt and Negri(1997; 2001; 2004). Hardt and Negri have elaborated on the economic postmodernization with the notion 'immaterial labor,' which blurs the line between economic (instrumental) actions and humane qualities as well as pertains to the potentiality of resistant practices against the power of modernity. From this perspective, progamers' labor is understood as 'affective labor,' an aspect of immaterial labor with the potentiality of resistance. However, meticulous examination of progamers' labor in this study reveals that progamers control their affects systematically, strategically, and rationally for their materialistic success. Progamers, while performing postmodern mode of labor, are subordinate to modern work ethics, which lead them to lose the potentiality of resistance. Consequently, while the discourses on game addiction and progamers outwardly form sharp contrast to each other, the two indeed are placed in tandem in the vein of modern work ethics of Protestantism.

Experimental animals have been used to biological and medical purposes and the animals must be, for these purposes, healthy and clean to microbial infection. However, the animals can be easily exposed to pathogenic microorganism via several routes. Of the routes, environmental conditions are the most important factors to keep the animals healthy and clean, especially air condition. Monitoring of air-condition has been required to keep the animal healthy and clean. However, any guideline is not available for experimental conditions with pigs. Therefore, the sampling times and points were compared in different conditions to establish an optimal protocol for monitoring of air borne bacteria. Tryptic soy agar(TSA), blood agar containing 5% defibrinated sheep blood and Sabraud dextrose agar(SDA) were used as media to capture total bacteria, pathogenic bacteria and fungi, respectively. Two methods, compulsive capture using an air-sampler and capturing fall-down bacteria were used to capture the microorganisms in the air. The points and time of capturing were different at each experiment. Air borne microorganisms were captured at three and five points in the open and closed equipments, respectively. Air was collected using an air-sampler for 1 min and 5 min and the agar plates as open status were left from 30 min to 2hr. At first, we monitored an experimental laboratory which dealt with several pathogenic bacteria and then, a protocol obtained from the investigation was applied to open or close experimental conditions with pigs. Number of bacteria was high from 10:00 to 15:00, especially on 13:30-15:30 but sharply decreased after 17:00. The tendency of the number of bacteria was similar between two methods even though the absolute number was higher with air sampler. Critical difference in the number of cells was observed at 5 min with air sampler and 2 hr with fall-down capturing method. However, 1 min with air sampler and 1 hr with fall-down capturing were the best condition to identify bacterial species collected from the air. Number of bacteria were different depending on the sampling points in closed condition but not in opened condition. Based on our results, a guide-line was suggested for screening air-borne microorganism in the experimental conditions with pigs.

Some artists and scientists in physics and animation originating from research on its form of expression thanks to the rapid development of the example in the late 20th century image production technology integrating existing media feature, perform a re-creation and pop culture content has been recognized as a key factor. animation of the modern emphasis is also commercial and artistic activities as show whether the artist can not be excluded that also target audience. The audience does not want only to receive offers simply 'seeing' and 'hearing' in the animation requires a more indirect mental met. the other side, the director should lead the audience to immerse myself in work as intended mystification induce the world. where a conflict occurs between the audience and the director and The director needs to have its troubleshooting point to 'Technology of the communication'. Which is reduced to 'How will tell,' is technology communication technologies that are abbreviated representations of animation director is accessible to the audience and it is a close relationship between the psychological aspect of audience. Because, the audience is reproduced in a limited space, but he called on the board of directors and the same time the screen, the audience located at reception and the director located at provide. It is given. led force is given to the director. for this reason, The director needs to pay attention to the psychological aspect of audience this can be explained based on psychoanalytic theory. In this paper, "How can you lie to the audience and the director is the same line?" put down logic that is the animation audience under the logic that takes place visually capture phenomenon "selective attention" and sub-concept of "goal-directed selection' and 'stimulus-driven capturel' for theory of psychology. also, Induction device to elicit selective attention of the audience accordingly, let's consider whether and how they apply in animation.

This paper aims to investigate ideological preferences of news media outlets by looking at the news coverage of North Korea-Russia summit in April, 2019. The meeting has gained attention in South Korea, China, Japan and America in that the historical meeting will reflect the future direction for denuclearization on the Korean peninsular and the peace in the world. Given this, in particular, a special attention is paid to the editorials and headlines of news articles reported in two Korean quality newspapers, DongA Ilbo and Hankyoreh because both are quality newspapers, but are ideologically different. To achieve objectivity and fairness, the same issues dealt with during the summit were compared and analyzed within Martin and White (2005)'s Appraisal framework. As a result, it was found that in editorials of DongA Ilbo showed a negative stance to the summit by employing the 'attitude' factor, whereas the Hankyoreh was overwhelmingly positive toward the issue, also by employing the 'attitude' factor. The political stance is likely to be in line with those shown in the headlines of news articles from each newspaper. That is, it is clear that each news outlet shows its ideological stances to news consumers through linguistic expressions, in that both editorials and the headlines of news articles express their political preferences to the summit by means of linguistic appraisals.

Calli were induced from diploid and haploid tobacco after 4 weeks and maintained on MS medium with combination of 2.0 mg/L 2,4-D,0.1 mg/L BAP and 2.0 mg/L kinetin. Suspension cells were screened through 65 $\mu$m-nylon mesh and 100 $\mu$m-mesh, then they were smeared on selection medium combined with cadmium and PFP by using the low melting agarose of 0.8%. After 30days smeared cultures of the medium the cell was treated with 500 $\mu$M and 1000 $\mu$M to select the resistant cell line were selected. Plant regeneration was induced from the selected cell lines on medium with 0.5, 1.5, 2.0 mg/L BAP and on media with combination of auxin and BAP under 500 $\mu$M and 1000 $\mu$M cadmium. At this time, plant regeneration was achived on cadmium free medium. In case of haploid, occurred from the cell line which is selected in medium with cadmium and PFP. In case of diploid regeneration occurred is in the medium with cadmium alone. The plantlet regenerated from cadmium resistant calli grew well in cadmium 500 $\mu$M. Protein pattern of leaf, root, stem of regenerated plants was analyzed. The quantum was 6.5188 ug/mg.fr.wt in the leaf of plant, 5.3611 ug/mg.fr.wt in the stem, 3.0213 ug/mg.fr.wt in the root. On the other hand, 5.9652 ug/mg.fr.wt. in the leaf of control, 3.5974 ug/mg.fr.wt in the stem of the control, 4.3766 ug/mg.fr.wt. in the root of the control. The one dimension bends regenerated from cadmium resistant calli resistant to cadmium in leaf were 49 involving 198.7KD etc. Disappeared were 4 involving 160.5KD etc, The protein bends were combinized were 3 involving 83.4KD etc. The bends resistant to cadmium stress in stem were 41 involving 4.3KD etc. Disappeared were 5 involving 114.8KD etc. The protein bends combinized were 6 involving 128.7KD etc. The bends which had the resistance to cadmium stress in root is 27 in volving 166,9KD etc. The bends which disappeared were 198.7KD etc. There were 5 involving 83.4KD etc.

This paper aims to investigate the cultural conflicts and characteristics of anti-Korean Wave discourse taken placed among Southeast Asian countries. To do this, it takes Vietnam and Indonesia as the study cases, which have been showing a trend of anti-Korean Wave discourse as well as high popularity of Hallyu. As research methods, the paper analyzes both on-line discourses of anti-Korean Wave and the email audience interviews from both countries. The results show some significant differences between the two countries as well as the similarity that Anti-Korean Wave discourses have been actively produced and disseminated through on-line media. As for Indonesia, the Anti-Korean Wave discourse pivots on the elements clashing between Indonesia's religion and cultural values and Korean consuming culture. According to the Anti-Korean Wave discourse, K-pop contents and entertainers are criticized for damaging the society's morals and cultural identities based on Islamic rules and values. Thus, the sentiment of the Anti-Korean Wave is likely to lead to the cultural nationalism for the sake of their cultural identity. As for Vietnam, anti-Korean Wave discourse mainly consists of issues on enthusiastic K-pop fans' anti-social behaviors and generational conflicts which are presumed attributed as the chief factor of the Anti-Korean Wave. In the Vietnamese discourse, social elites and adults treat the enthusiastic K-pop fans as those who are in need of educational care or psychological therapy. Unlike the Indonesian case, anti-Korean Wave discourse in Vietnam criticized the K-pop and the performer's competence for being cheap sexy and incompetence. They also denounce Korean dramas for their trite, typical story lines, use of excessive emotion, and unrealistic nature. However, the two country's interview participants have in common both acknowledged that rather than considering the Anti-Korean Wave as an issue that needs to be resolved it should be embraced as a natural cultural phenomenon.

This study deals with the production system of the superhero animation that are based on DC comic books and are produced by Warner Brothers company, and tries to find out ways in order to vitalize the new window of the animation market. 28 superhero animations released from 2007 until 2017 are analyzed. Several critical points are drawn out and can be applied to the Korean animation industry. There are two categories, one is about the management of the production system, and the other is about the subcontract system. In managing the production system, there are three points: First, there are several people who play the role of either a producer or a director many times. Second, producers used to work as a group. Third, some people work not only as a producer but also as a director. In carrying out outsourcing contracts, there are six points: First, only Korean and Japanese companies participate as subcontract companies. Second, about two companies used to take part in the subcontract production in a year. Third, in case of number of people involved in production, there are more Japanese than Korean. Fourth, Japanese companies deal with some parts of the pre-production as well as the main production in . Fifth, a Japanese company has a sub-subcontract with a Korean company in one episode of . Sixth, Korean companies mostly focus on the production part of key animation. Important points that the Korean production system has to consider are also suggested under the two categories. In the production system management, there are two points. It is needed to make use of the group producer system, and it is critical to develop the story line of universe type such as DC Universe. In case of the outsourcing production system, it is essential to keep up educating 2D type of animation and, at the same time, to participate actively in the global outsourcing production. By considering these crucial points, it is expected to keep producing animation that can be used for the media window such as IPTV.

Over the past decade, there has been a rapid diffusion of electronic commerce and a rising number of interconnected networks, resulting in an escalation of security threats and privacy concerns. Electronic commerce has a built-in trade-off between the necessity of providing at least some personal information to consummate an online transaction, and the risk of negative consequences from providing such information. More recently, the frequent disclosure of private information has raised concerns about privacy and its impacts. This has motivated researchers in various fields to explore information privacy issues to address these concerns. Accordingly, the necessity for information privacy policies and technologies for collecting and storing data, and information privacy research in various fields such as medicine, computer science, business, and statistics has increased. The occurrence of various information security accidents have made finding experts in the information security field an important issue. Objective measures for finding such experts are required, as it is currently rather subjective. Based on social network analysis, this paper focused on a framework to evaluate the process of finding experts in the information security field. We collected data from the National Discovery for Science Leaders (NDSL) database, initially collecting about 2000 papers covering the period between 2005 and 2013. Outliers and the data of irrelevant papers were dropped, leaving 784 papers to test the suggested hypotheses. The co-authorship network data for co-author relationship, publisher, affiliation, and so on were analyzed using social network measures including centrality and structural hole. The results of our model estimation are as follows. With the exception of Hypothesis 3, which deals with the relationship between eigenvector centrality and performance, all of our hypotheses were supported. In line with our hypothesis, degree centrality (H1) was supported with its positive influence on the researchers' publishing performance (p<0.001). This finding indicates that as the degree of cooperation increased, the more the publishing performance of researchers increased. In addition, closeness centrality (H2) was also positively associated with researchers' publishing performance (p<0.001), suggesting that, as the efficiency of information acquisition increased, the more the researchers' publishing performance increased. This paper identified the difference in publishing performance among researchers. The analysis can be used to identify core experts and evaluate their performance in the information privacy research field. The co-authorship network for information privacy can aid in understanding the deep relationships among researchers. In addition, extracting characteristics of publishers and affiliations, this paper suggested an understanding of the social network measures and their potential for finding experts in the information privacy field. Social concerns about securing the objectivity of experts have increased, because experts in the information privacy field frequently participate in political consultation, and business education support and evaluation. In terms of practical implications, this research suggests an objective framework for experts in the information privacy field, and is useful for people who are in charge of managing research human resources. This study has some limitations, providing opportunities and suggestions for future research. Presenting the difference in information diffusion according to media and proximity presents difficulties for the generalization of the theory due to the small sample size. Therefore, further studies could consider an increased sample size and media diversity, the difference in information diffusion according to the media type, and information proximity could be explored in more detail. Moreover, previous network research has commonly observed a causal relationship between the independent and dependent variable (Kadushin, 2012). In this study, degree centrality as an independent variable might have causal relationship with performance as a dependent variable. However, in the case of network analysis research, network indices could be computed after the network relationship is created. An annual analysis could help mitigate this limitation.

The stagnant growth in 3D market due to 3D movie contents shortage is encouraging development of techniques for production cost reduction. Elimination of vertical disparity generated during image acquisition requires heaviest time and effort in the whole stereoscopic film-making process. This matter is directly related to competitiveness in the market and is being dealt with as a very important task. The removal of vertical disparity, i.e. image rectification has been treated for a long time in the photogrammetry field. While computer vision methods are focused on fast processing and automation, photogrammetry methods on accuracy and precision. However, photogrammetric approaches have not been tried for the 3D film-making. In this paper, proposed is a photogrammetry-based rectification algorithm that enable to eliminate the vertical disparity precisely by reconstruction of geometric relationship at the time of shooting. Evaluation of proposed algorithm was carried out by comparing the performance with two existing computer vision algorithms. The epipolar constraint satisfaction, epipolar line accuracy and vertical disparity of result images were tested. As a result, the proposed algorithm showed excellent performance than the other algorithms in term of accuracy and precision, and also revealed robustness about position error of tie-points.

The immune system acts to protect the host from infectious agents that exist in the environment and from other noxious insults. The immune system has two functional divisions: the innate and the acquired. Both components involve various factors such as cytokines. A number of methodologies exist to assess aspects of immune function. There are large inter-individual variations in many immune functions even among the healthy. Genetics, age, gender, smoking habits, habitual levels of exercise, alcohol consumption, diet, stage in the female menstrual cycle, stress, history of infections and vaccinations, and early life experiences are likely to be important contributors to the observed variation. While it is clear that individuals with immune responses significantly below 'normal' are more susceptible to infectious agents and exhibit increased infectious morbidity and mortality, it is not clear how the variation in immune function among healthy individuals relates to variation in susceptibility to infection. Oriental medicine is an important factor contributing to immune competence. The author investigated the immune enhancement effects of Bojungikkitanggami-bang (BITB). The forced swimming test (FST) has been used as a screening model for new immune enhancement agents. In the present study, the author investigated the effects of BITB on FST and blood biochemical parameters related to fatigue, glucose (Glc); blood urea nitrogen (BUN); lactate dehydrogenase (LDH); creatinine; and total protein (TP). The author found that BITB (1 g/kg) significantly reduced the immobility time in the FST compared to the control. In addition, the contents of Glc, LDH, BUN, TP in the blood serum were increased in BITB (1g/kg)-fed group. Also, the author investigated the effects of BITB on the production of cytokines in human T-cell line, MOLT-4 cells. BITB (1 mg/ml) significantly increased the interferon (IFN)-vproduction compared with media control (about 2.2-fold for IFN-γ) at 24 h. However, BITB has not affect the production of IL-2 and IL-4. In addition, BITB increased the protein expression level of IFN-γ in MOLT-4 cells. Thus, BITB may have therapeutic value in generating or enhancing immune function in a clinical setting.
