CCN(: Content Centric Network)은 기존 네트워크 구조를 개선하기 위해 등장한 네트워크로, 주소 대신 콘텐츠 이름에 기반하여 통신한다. 캐시를 활용하여 트래픽을 분산시키고, 중간노드에서 콘텐츠를 전송함으로써 응답시간 감소 효과를 가져오고 있다. 본 논문에서는 CCN 환경에서 제한된 CS 공간을 효율적으로 활용할 수 있도록 인기도를 고려한 캐시 정책을 제안한다. 어떤 콘텐츠에 우선순위를 두어 저장하고 방출할지를 결정하는지에 따라 CCN의 성능이 크게 달라질 수 있다. 가장 효율적인 캐시 교체를 위해 생성자 인기도, 생성자 거리, 콘텐츠 히트수를 기반으로 콘텐츠 인기도를 계산해 우선순위를 정하는 실시간 콘텐츠 인기도 기반 효율적인 캐시 교체정책을 제안하였으며, 새로운 정책의 효율성을 실험을 통해 입증하였다.

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.

Anime is very popular in Japan, it has also gained a following in America and is beginning to hit the mainstream. Anime is gaining popularity in the United States as it is shown more on television, most noticeably on the Sci-Fi Channel with shows such as Saturday Anime and during Anime Week and on Cartoon Network with shows such as Sailor Moon and Dragon Ball Z being shown every weekday during the Toonami block. 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.

This study analyzes circulation statistics of television tie-in picture books from the Wake County Public Library System in North Carolina to determine their popularity among patrons. Caldecott winning picture books were used as a point of comparison. This study also examined OPAC holdings from North Carolina public libraries to determine television tie-in picture book popularity among collection builders. The findings of the study show that television tie-in picture books are found to some degree in the vast majority of North Carolina public libraries, and are more popular than award winners in the Wake County system.
