Purpose: Visual communication is the act of using elements and components that can be seen. Some of the elements include images, illustrations, drawings, and videos. The purpose of this research is to check if there is the meaningful role of visual communication for emotional marketing plan. Research design, data and methodology: The present author firstly tried to obtain prior knowledge based on numerous previous literature through qualitative content method, investigating and searching related topic in 'Scopus' and 'Google Scholar' which is one of the most famous database. This methodology has already been proved the credibility and conformability by prior researchers. Results: The current study looks at four basic aspects that will assist in analyzing the findings and results from different peer-review articles. The section will cover social media, videos, podcasts, and ads. Conclusions: Several studies also affirmed that increased use of the internet and internet for marketing causes psychological issues among adolescents. Only adults should view some of the marketing ads, but if they pop into an adolescent browser, it may cause some harmful effects. Therefore, the study concluded that moderation of online visual adverts should be done to ensure only the targeted customers view the advert.

We study online gaming regulations and examine the reactance and attitude of the targeted group. To be specific, we focus on the 'Shutdown Law' due to its scope and magnitude of its influence. The Shutdown Law was enforced to prevent adolescence's immersion in or addiction to online gaming; however, its effectiveness has yet to reach a consensus. Our empirical findings show that the reactance to the regulation is stronger as game usage increases; surprisingly the effect of game usage on reactance weakens among the affected adolescence's group, compared to the adult counterpart. Furthermore, heavy users in the targeted group are more likely to play online gaming to mingle with their peers, and thus more likely to play other activities that friends participate in. These results suggest that online games play a role to cultivate peer-culture among adolescence and facilitate their communication.

Recently, with the development of wireless communication technologies and mobile equipments, various studies on mobile P2P networks have been conducted. In this paper, we propose an advertisement dissemination method considering peer's mobilities and preferences in mobile P2P networks. The proposed scheme generates a peer's preference through the analysis of users' activities to disseminate advertisements with user preferences. To reduce duplicated advertising messages and improve reception ratio, the priority of advertisement re-dissemination is determined according to peer's preferences, mobilities, and advertisement reception ratio. We improve the participation rate of the advertisement dissemination of mobile peers using the incentive mechanism in mobile P2P networks. To show the superiority of the proposed scheme, we compare it with the existing scheme in terms of the number of messages and accuracy.

Emerging social networking services provide a new paradigm for human-to-human communication. However, these services are centralized and managed by single service provider. In this paper, we propose MicroPost, a decentralized event notification service architecture for social applications based on publish/subscribe model. In our design space, event brokers are structured as an overlay network which provides the substrate of distributed peer-to-peer lookup service for storing and retrieving subscriptions with hashed keys. Event clients interact with event brokers to publish or subscribe social messages over the wide-area network. Using XML standards, we present an efficient algorithm to forward events for rendezvous-based matching in this paper. In our design space, the cost of routing is O(${\omega}log_kN$), where N is the number of event brokers, ${\omega}$ is the number of meta-data obtained from event messages, and k is a constant, which is selected by our design, to divide the identifier space and to conquer the lookup of given key. Consequently, what we achieved is an asynchronous social messaging service architecture which is decentralized, efficient, scalable, and flexible.

More and richer information sources and services are available on the web everyday. However, harmful information, such as adult content, is not appropriate for all users, notably children. Since internet is a worldwide open network, it has a limit to regulate users providing harmful contents through each countrie's national laws or systems. Additionally it is not a desirable way of developing a certain system-specific classification technology for harmful contents, because internet users can contact with them in diverse ways, for example, porn sites, harmful spams, or peer-to-peer networks, etc. Therefore, it is being emphasized to research and develop context-based core technologies for classifying harmful contents. In this paper, we propose an efficient text filter for blocking harmful texts of web documents using context-based technologies and examine which algorithms for feature selection, the process that select content terms, as features, can be useful for text categorization in all content term occurs in documents, are suitable for classifying harmful contents through implementation and experiment.

The purpose of this study were to investigate the effect of Family System Functioning, Parent & Child Factor and Parent-child Relation on Adolescent's Psychological Well-being (Family Life Satisfaction, Self-Esteem and Depression), and the causal relations of Adolescedent's Depression and Related Variables. The subjects were 532 triads of adolescents and their parents living in Seoul area, Korea. The survey methods were questionaires included FACES n, PAC Inventory, family life satisfactin scale, KMSS, Self-Esteem Inventory and CES-D, etc. Data were analyzed by frequencies, percentages, mean, standard deviation, paired t - test, Pearson's correlation , multiple regression, and path analysis The major findings were as follows: Family system functionings had a indirect effect through adolescents'family life satisfaction, self-esteem on adolescents'depression. The degree of openness of parent-adolescent communication and father's marital satisfaction had a indirect effect through adolescents'family life satisfaction on adolescents'depression. Adolescents'satisfaction with physical self, peer-relations and school life had a indirect effect through adolescents'self-esteem on their depression. Also adolescents'satisfaction with peer-relations and their fathers'depression had a direct effect on their depression.

Recently, DHT-based Structured P2P System have a attention to scalability and providing efficient lookup by routing. Retrieving content of DHT-based P2P require knowledge of the exact identifier of sharing file. But user may wish to search for sharing file using descriptive keyword or content. To resolve the problem, this paper propose Extended-CAN mechanism to support keyword search. We defined content-based keyword and identifier of sharing file, and PLS extended to KID and CKD for keyword, common keyword processing. As a result, Extended-CAN mechanism provide efficient keyword search for DHT-based Structured P2P System.

In this article, we model the distributed relay assignment network as a many-to-one matching market with peer effects. We discuss two scenarios for throughput optimization of relay networks: the scenario of aggregate throughput optimization and the scenario of fairness performance optimization. For the first scenario, we propose a Mutual Benefit-based Deferred Acceptance (MBDA) algorithm to increase the aggregate network throughput. For the second scenario, instead of using the alternative matching scheme, a non-substitution matching algorithm (NSA) is designed to solve the fairness problem. The NSA improves the fairness performance. We prove that both two algorithms converge to a globally stable matching, and discuss the practical implementation. Simulation results show that the performance of MBDA algorithm outperforms existing schemes and is almost the same with the optimal solution in terms of aggregate throughput. Meanwhile, the proposed NSA improves fairness as the scale of the relay network expands.

This research investigates the role of entrepreneurial leadership in micro-enterprise development in the district of Majalengka in West Java, Indonesia. This study applied a qualitative content analysis method to understand the phenomenon of micro-enterprises comprehensively. The data of this research was collected using surveys, interviews, and a group discussion. The findings indicated that technological information adaptation plays a crucial role in the development of micro-enterprise development. Since the group of millennials dominated the leadership, it has provided more creativity by implementing technological information instead of the previous generation that faced difficulties in adopting the technology. This study noted that inadequate technology adaptation makes micro-business gradually lose customers, and the business was threatened to close. Meanwhile, the role of leadership drives the business development, sales have risen, the number of products has been increasingly diverse, and business capital and number of employees have grown. The establishment of an entrepreneur group could facilitate peer-to-peer contact, knowledge transfer, training, and intervention to enhance leadership and business development. This finding pointed out that the leadership will successfully influence business development when supported by several characteristics such as manage the business, capture opportunities, confidence, firmness, personal integrity, communication, and social and technical expertise.
