The growing popularity of mobile application has led to researchers and practitioners needing to understand users' mobile application download behaviors. Using large-scale transaction data obtained from a leading Korean telecommunications company, we empirically explore how application download rank, which appears to users when they decide to download a new application, affects their extended mobile application download. This terminology refers to downloading an additional application in the same category as those that they have already downloaded. We also consider IT characteristics, user characteristics, and application type that might be associated with the extended application download. The analysis generates the following result. Overall, a higher rank of a new application encourages the extended application download, but the linear relationship between the rank and the extended application download disappears when critical rank points are incorporated into the model. Further, no quadratic effect of rank is found in the extended application download. Based on the results, we suggest theoretical and managerial implications.

Software reconfigurable radio will give future users a number of benefits like global roaming, multi mode, multi band, and multi standard. It will also offer complete programmability and reconfigurability to both multi mode and multi functional communication terminal and network nodes. This configuration will be implemented by application of different combination of radio configurable software. In this paper, It proposes the algorithm needed for reconfiguration with basic explanation of the software download. A description of an implementation such reconfiguration processes as partial download and full download and critical and non-critical download installation using the registration table in included.

In this paper, we proposed a Sequential Download System(SDS) to provide high steaming QoS in p2p network. SDS is able to receive a media file simultaneously from multiple source peer by download manager and deal with unexpected leave of source peer. Also It can provide stable streaming services with minimum buffering delay and manage request of other peer by memory map in process of downloading.

The purpose of this study is to search the correlation between real-time viewing and OTT VOD usage. The study is based on the ratings and VOD download data, collected from TNmS and pooq. And this study focused on the ratings, 2049 ratings, OTT VOD download over the past 7 days, OTT VOD download over the past 30 days. The results showed that there were positive correlation in all genres(drama, entertainment, current affairs). First, there was a correlation between ratings and OTT VOD download over the past 7 days, between 2049 ratings and OTT VOD download over the past 7 days. Next, there was a correlation between ratings and OTT VOD download over the past 30 days, between 2049 ratings and OTT VOD download over the past 30 days. Finally, there was somewhat different among rankings of the ratings and VOD download.

An improvement of a mobile game content production and a service technology are bringing an explosive increase of a mobile game market. Currently serviced mobile games are using a WAP method and a download method. Because of technical problems, we couldn't develop the mobile game content which sequentially linked WAP->download and download->WAP. In this study, we design and develop the mobile game content which sequentially linked WAP->download and download->WAP. In the proposed method, we can linked the stage and the ranking information as sharing a data on real time that it is impossible in the previous mobile game content.

Mobile applications are significantly impacting people's smart phone using behavior and mobile industry value chain. By examining sources of data on mobile applications use, this study presents evidence about what factors would affect the amount of apps download, which may be useful to guide app designers and publishers to develop more persuasive new apps and marketing strategies. The results indicated app ranking had effect on download amount of apps in both Android app market and Apple app store, while prices of apps had no impact on the amount of download. App type, developer experience, and locality had effect on the amount of download only for paid apps in Apple app store.

본 논문에서는 P2P 네트워크 상에 분산되어 있는 파일들을 수집하고 피어의 신뢰도가 낮은 접속에도 끊김 없는 스트리밍 서비스를 제공하기위해 Sequential Download System(SDS)을 제안하였다. SDS는 Download Manager를 이용하여 여러 피어로부터 파일을 수신하고, 파일 수신 시에 피어의 갑작스런 이탈에 대처하며 스트리밍 시 발생하는 버퍼링 시간을 최소화하여 안정된 스트리밍을 제공하게 된다. 또한 Memory map을 이용하여 다른 피어의 요청에도 대처할 수 있다.

This paper discribes the differen-ces between making handset sample and handset massproductions. To save time during mass production, Calibrat-ion should be automated and SW do-wnloading also be automated and Par-allely done. All this processes are des-cribed here. Especially Calibration are more detaily explained in this paper.
