Recently, the traditional call center, which has an important role as the customer's primary contact point, has been transformed into the omni-channel contact center which supports an additional variety of access channels in addition to phone calls in order to improve customer accessibility and convenience. The omni-channel contact center has agents on each channel which are vital in determining the response rate and waiting time for the customer. In traditional call centers, agents can be assigned to a call based on the characteristics of the call, however in omni-channel contact centers, the characteristics of issues vary and come in through multiple channels, each with their own characteristics, making it difficult to assign the appropriate agent for the issue. Customers must also be processed at the same time, adding an additional layer of complexity to the issue. This paper analyzes and simulates an omni-channel contact center that accommodates email, chat, voice calls and video consultation, and investigates how to optimize the allocation of agents.

In the area of wireless sensor networks, sensor coverage and network connectivity problems are caused by a limited detection range and the communication distance of the nodes. To solve the coverage and connectivity problems, many studies are suggested, but most research is restricted to apply into the real environment because they didn't consider various environmental factors on wireless sensor network deployment. So in this paper, we propose a node deployment strategy considering environmental factors and the number of nodes in surveillance and reconnaissance sensor networks(SRSN). The proposed node deployment method divides the installation of the surveillance and reconnaissance sensor networks system into four steps such as identification of influences factors for node placement through IPB process, sensor node deployment based on sensing range, selection of monitoring site, and relay node deployment based on RF communication range. And it deploys the sensor nodes and relay nodes considered the features of the surveillance and reconnaissance sensor network system and environmental factors. The result of simulation indicates that the proposed node deployment method improves sensor coverage and network connectivity.

적들과 마찬가지로 로마인들은 가능한 곳에서는 적보다 높은 지형에 위치함으로써 중요한 이점을 얻으려고 노력하였다. 이러한 위치 선정은 화기의 사거리를 신장시켰고 충격을 가하는 데에 소요되는 육체적인 노력을 감소시킴으로써 충격시의 효과를 증가시켰다. 그리고 칼과 창을 사용하는 것을 용이하게 하였다. 항상 그랬던 것은 아니었지만 통상적으로 케사르는 그의 정예 대대들을 레지온의 첫번째 열에 배치하여 전투의 최초 충격으로부터 최대한의 결과를 얻으려고 하였다.

수익성 없는 고객주의나 단기적인 수익성만을 강조하는 무시 주의는 CRM과는 배치되는 사고이다. CRM은 장기적인 가치를 극대화하는 것을 목표로 한다. 또 CRM은 고객과 기업이 합리적인 혜택을 주고 받는 과정에서 상호의 이익을 극대화하는 것을 목표로 한다. 필자는 이번호부터 고객관계관리의 전략적인 가치를 비롯해 조직의 혁신, 정보기술과의 연계방안, 발전 방향에 대해 살펴보고자 한다.

본 연구는 유튜브 조회수 20억뷰를 돌파하고 기네스북에 오른 강남스타일 뮤직비디오의 시각적 몰입감에 대한 분석을 통해 이를 극대화하는 전략을 찾고자 한다. 분석 결과 뮤직비디오는 댄스 및 퍼포먼스, 출연자와 스타일, 장소 배경 등의 콘셉트가 일관성이 있고 창의적일수록, 주요인물의 등장순서와 배치, 비주얼의 양적 질적 변화, 청각 중심이 시각에 일치되어 기승전결이 고조될수록 시각적 몰입감이 극대화되었다. 향후 제 2, 제 3의 강남스타일 등 한류(韓流)와 유튜브 진출을 목적으로 하는 뮤직비디오 제작을 위해서는 창의적 '시각적 콘셉트'를 발굴하고, 검증된 '시각적 기승전결'을 강화하여 시각적 몰입감을 극대화하는 전략이 필요하다.

The purpose of this study was to investigate the differences in the school life satisfaction of middle school students according to self-directed learning capability and emotion regulation strategy. The subject of this study were 499 middle school students in Daegu. In order to analyze the data, two way ANOVA were employed for analysis and $Scheff{\acute{e}}$ test for post-hoc analysis. The main finding of this study were as follows; First, there were significant differences in the school life satisfaction of middle school students according to self-directed learning capability and behavioral emotion regulation strategy. Second, there were significant differences in the school life satisfaction of middle school students by cognitive emotion regulation strategy. But there were no significant differences in the school life satisfaction according to self-directed learning capability and cognitive emotion regulation strategy. Third, there were significant differences in the school life satisfaction of middle school students according to negative avoidant and emotion regulation strategy. However there were no significant differences in the school life satisfaction according to self-directed learning capability and negative avoidant emotion regulation strategy.

Rapid advances in mobile computing and the availability of wireless communications will soon provide mobile users with the ability to access data regardless of the location of the user or of the data. SRA(Static Replica Allocation) that is traditional scheme has been used for the replication method on the server. This replicates the data on the replica server after a moving host has been transferred to the cell. This strategy is simple and can easily relocate data. However, if a mobile user does not exist in the cell, the replicated data can be deleted in order to maintain data consistency. In addition to, if the mobile host leaves from replicated cell, it is difficult to access data in terms of replication route. Therefore, this paper proposes a new method of relocation based on data consistency strategy called USRAC(User Selection Replica Allocation based on Consistency) and also analyzes access cost according to the moving rate of mobile users, according to the access rate of mobile hosts, and according to the number of cells of mobile users and mobile hosts.

Seoul introduced the shared bicycle system, "Seoul Public Bike" in 2015 to help reduce traffic volume and air pollution. Hence, to solve various problems according to the supply and demand of the shared bicycle system, "Seoul Public Bike," several studies are being conducted. Most of the research is a strategic "Bicycle Rearrangement" in regard to the imbalance between supply and demand. Moreover, most of these studies predict demand by grouping features such as weather or season. In previous studies, demand was predicted by time-series-analysis. However, recently, studies that predict demand using deep learning or machine learning are emerging. In this paper, we can show that demand prediction can be made a little better by discovering new features or ordering the importance of various features based on well-known feature-patterns. In this study, by ordering the selection of new features or the importance of the features, a better coefficient of determination can be obtained even if the well-known deep learning or machine learning or time-series-analysis is exploited as it is. Therefore, we could be a better one for demand prediction.
