  • Content Centric Network (CCN) is a network that emerged to improve the existing network structure and communicates based on content names instead of addresses. It utilises caches to distribute traffic and reduce response time by delivering content from intermediate nodes. In this paper, we propose a popularity-based caching policy to efficiently utilise the limited CS space in CCN environment. The performance of CCNs can vary significantly depending on which content is prioritised to be stored and released. To achieve the most efficient cache replacement, we propose a real-time content popularity-based efficient cache replacement policy that calculates and prioritises content popularity based on constructor popularity, constructor distance, and content hits, and demonstrate the effectiveness of the new policy through experiments.

  • This study investigated how peer popularity is linked to children's understanding, moral judgment, and emotional reactions about three different types of lies. Participants were second (n=53) and fourth (n=54) grade children. Results showed that (1) popular children afforded better understanding of white lies than unpopular children; most children understood the definition of an antisocial lie, but not a trick lie. (2) Popular children rated lies more positively than unpopular children. Second graders did not differentiate between the morality of white and trick lies; fourth graders rated white lies as the least serious type of lie. (3) Second graders anticipated greater positive emotional reaction for antisocial lies and greater negative emotional reaction for white lies and trick lies, respectively, than fourth graders.

In this paper, I present the key factors behind the success of anime in USA. To find out the factors, I research literature and simple survey. The differences of anime from us animation make anime popular. Anime-related goods such as video games, trading cards, and characters' jewelry aid the anime growing popularity. A booming trend in admiration for Japan is one of the key factors behind anime's success. In spite of disputing about Japanese animation, anime is starting to have some influence on US animation and also young American. Anime's success factors in USA could suggest that Korean Manhwa and Korean animation have to prepare strategies for rising popularity in oversea.

  • Caching of frequently accessed data in multi-hop ad hoc environment is a technique that can improve data access performance and availability. Cooperative caching, which allows sharing and coordination of cached data among several clients, can further en-hance the potential of caching techniques. In this paper, we propose a fuzzy cooperative caching scheme in mobile ad hoc networks. The cache management of the proposed caching scheme not only uses adaptively CacheData or CachePath based on data sim-ilarity and data utility, but also uses the replacement manager based on data pro t. Also, the proposed caching scheme uses a prefetch manager. When the TTL of the cached data expires, the prefetch manager evaluates the popularity index of the data. If the popularity index is larger than a threshold, the data is prefetched. Otherwise, its space is released. The performance of the proposed scheme is evaluated analytically and is compared to that of other cooperative caching schemes.

  • A retrieval performance of VOD sever is estimated by how quickly it services popular videos to users and how many users it is able to service. Each video data is placed on heterogeneous disks and placement techniques are various, retrieval performance is under the control of these elements, so that a retrieval performance is affected by placement policy. In this paper, we place video data considering their characteristics, especially, we place videos distributively according to their popularity. To verify our policy, we make various environment of experiment, estimate a placement policy using popularity of videos and a contrary policy, and compare them.

  • The data grid provides geographically distributed resources for large-scale applications. It generates a large set of data. The replication of this data in several sites of the grid is an effective solution for achieving good performance. In this paper we propose an approach of dynamic replication in a hierarchical grid that takes into account crash failures in the system. The replication decision is taken based on two parameters: the availability and popularity of the data. The administrator requires a minimum rate of availability for each piece of data according to its access history in previous periods, but this availability may increase if the demand is high on this data. We also proposed a strategy to keep the desired availability respected even in case of a failure or rarity (no-popularity) of the data. The simulation results show the effectiveness of our replication strategy in terms of response time, the unavailability of requests, and availability.
