The collaboration productively interacting between multi-agents has become an emerging issue in real-world applications. In reinforcement learning, multi-agent environments present challenges beyond tractable issues in single-agent settings. This collaborative environment has the following highly complex attributes: sparse rewards for task completion, limited communications between each other, and only partial observations. In particular, adjustments in an agent's action policy result in a nonstationary environment from the other agent's perspective, which causes high variance in the learned policies and prevents the direct use of reinforcement learning approaches. Unexpected social loafing caused by high dispersion makes it difficult for all agents to succeed in collaborative tasks. Therefore, we address a paradox caused by the social loafing to significantly reduce total returns after a certain timestep of multi-agent reinforcement learning. We further demonstrate that the collaborative paradox in multi-agent environments can be avoided by our proposed effective early stop method leveraging a metric for social loafing.

Purpose: The purpose of this systematic review is to explore end-of-life (EOL) care planning and the impact of socioeconomic status (SES) among people who identify as Black or African American. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) were used to guide and inform this systematic review process. The following academic electronic databases with publications that reflected the interdisciplinary fields related to the research objective were searched: APA PsycINFO, CINHAL, PubMed, Scopus, and Social Work Abstracts. Results: After the authors conducted the search, 14 articles (from 13 studies) ultimately met the criteria for inclusion. The results substantiated significant concerns highlighted in previous literature regarding SES and its relation to EOL planning, but also revealed an absence of original work and interventions to increase engagement in EOL planning among Black and African American populations. Conclusion: Black individuals deserve an equitable EOL experience. Researchers, practitioners, and policymakers need to move towards advocacy and action to meet this important need.

The purpose of this study examined how post-traumatic stress, caused when internet users in web portal or social media are defamed in cyberspace, influence on coping behaviour, through the Theory of Reasoned Action's two major factors: Attitude on behaviour and subjective norm. In so doing, it aims to provide a technical and political solution that would fundamentally prevent future victims in cyberspace. In an effort to examine its research theory, a survey was conducted on people who have had the experience of being defamed in cyberspace. The results showed, first, hypersensual has no significant influence over attitude on behaviour and subjective norm. Second, intrusion has no significant influence over attitude on behaviour and subjective norm. Third, avoidance showed significant influence over attitude on behaviour and subjective norm. Fourth, attitude on behaviour and subjective norm showed significant influence on behaviour. This study has both theoretical and practical significance; Unlike previous studies on cyber defamation with qualitative research method, this study employed quantitative method through theory-based approach. In other words, the researcher did not arbitrarily set variables, but utilized the Theory of Reasoned Action for examination.

Purpose: This study was done to identify the distribution and related factors for stage of change for wearing hearing protection devices (HPDs) by workers in environments with high noise. Predictors of Use of Hearing Protection Model and Trans-theoretical Model were tested. Methods: The participants were 755 workers from 20 noisy work places in Busan and Gyeongnam. Data were collected from January to April 2008 using self-administered questionnaires, and analyzed using multiple logistic regression. Results: There were significant differences in social mode (OR=1.35, 95% CI: 1.06-1.73) between precontemplation/contemplation and preparation stage, in males (OR=2.36, 95% CI: 1.24-4.51), workers with high school education or less (OR=1.39, 95% CI: 1.28-2.78), shift workers (OR=1.50, 95% CI: 1.02-2.21), workers who previously worked in noisy places (OR=1.39, 95% CI: 1.20-2.34), and workers who had previous hearing examinations (OR=1.89, 95% CI: 1.25-2.85), in the social model (OR=1.59, 95% CI: 1.42-1.78), and self-efficacy (OR=1.05, 95% CI: 1.02-1.08) between workers in preparation and action stages, in length of time working in noisy work places (OR=2.26, 95% CI: 1.17-4.39), social model (OR=1.66, 95% CI: 1.33-2.08), and perceived benefit (OR=0.95, 95% CI: 0.93-0.97) between action and maintenance stage. Conclusion: Social model was a common factor showing differences between two adjacent stages for wearing HPDs. The results provide data for developing programs to encourage workers to wear HPDs and application of these programs in work settings.

Konstantin S. Stanislawski(1863-1938) is one of the great acting-teachers and directors. Especially his 'System' influences this day like his period so many actors and directors in the world. In Korea, Stanislawski was introduced at first in 1920's by Kim, Woojin, dramatist. After that time, his system was influenced fast everyone in the korean drama world. As a result, so many translations of his books and researches of his system are done until nowadays, but it is not perfect for the correct understanding of Stanislawski and his system. It seems to be several causes in this misunderstanding. And the purpose of this thesis is at first to observe historically the results of researches and translations on Stanislawski and his system in Korea and then to bring it in order according to characteristics. In this thesis are the process of reception observed dividing 4 periods. The first period is from the beginning to the liberation in 1945. The second is to 1980's and the next is to the year 2000. And the final period is from that time to the present time. As a result are several characteristics found as followings: 1) translations of Stanislawski's first book like other books, for example, Building a Character and Creating a Role, an Actor Prepares, are fast all secondhand translations, that means, man translated it not from russian direct but japanese or english. It caused man to misusing of terms and then misunderstanding on the system. 2) the researches on Stanislawski in are fast all concentrated on the book, an Actor Prepares, so this leads man to regard it as his whole acting system. On the other hand, thesisses which deal with his last and final acting technique, "the Method of the physical Action" are relatively not so much. As though man knows the last, man used to think that the system is developed systematically from the psychological technique to the physical action or the method of the physical action is only the way to understand of stanislawski's acting method. The psychological method and the physical are not the divided, different acting technique, but pairs which are applied to different objects, that is, the actor himself and the role in texts. 3) the political aspects are not considered especially under the situation of Stalin's social realism. This lack of the political context having relation with the system acts as a obstacle upon understanding the correct, whole his system. But so many thesises on this theme in other countries are so vivacious. For example, man can find subjects like "Stanislawski and Meyerhold", "means of Stanislawski's method for theatres in the social context". There are also many interesting Questions related to the physical action. That is, is the physical action the final acting technique or the materialistic dialectical device to survive under the Stalin's rule? Is there some interrelations between stanislawski's physical action and Meyerhold's biomechanics? In conclusion, the researches on Stanislwski and his system are not enough to understand correctly and overcome the system. We have to start the research again at least from the direct translation his books written russian in order to apply it in a new times.

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.

For the thematic analysis, 'Social psychological components of the brand' based on social psychology was used for analyzing the cognitive aspects, the relational aspects, and the attitudinal aspects. The most common study was the study of the cognitive aspects, and relational aspects, and lastly the attitud inal aspects in order. The strategy was the most common research for the brand associated study. The ultimate point of the strategy is to get 'attitude'. From social psychology perspective, there is a cycle in the minds of consumers, 'Identification', 'Internalization', 'Conformity' and 'Compliance'. Structure of these relationships can provide a clue that consumers' attitude lead the consumers' action.

Although the Internet has been a important communication tool in modem societies, researchers did not pay attention to its' positive impacts on individual's psychological process. The Internet provides users with a unique environment such as visual isolation, non face-to-face communication, and easiness to escape from social influences. This environment enables people to take free action according to their personality and disclose themselves. From the uses and gratification perspective, the current research reveals that individuals with high extraversion are inclined to maintain social networking sites and those with high openness participate in web communities. The findings indicate that individuals' social use of the internet may reflect their personality. This study, also, reveals that controlling the big five personality dimensions, the amount of self-disclosure through ones' social networking site is positively related with subjective happiness. This finding suggests that like confession behaviors in religious or curing facilities, people can use the Internet as a therapeutic or a preventative method for promoting their well-being. Theoretical contributions and practical implications are discussed.
