최근 수년간 방송과 통신의 융합이 지속적으로 진행되고 있으며, 특히 홈 네트워크를 통한 방송 및 통신의 멀티미디어 콘텐츠의 공유 기기 시장이 비약적으로 성장하고 있다. 스마트폰을 비롯한 스마트 기기의 진보를 통하여 사진, 음악, 영상의 멀티미디어 콘텐츠에 대한 공유가 홈 네트워크 상에서 이루어 지고 있으며, 이러한 기술은 업계 표준으로 사용되고 있는 UPnP 및 DLNA에 기반하고 있다. 다만, 이러한 홈 네트워크 표준은 Peer-to-peer 네트워크를 근간으로 하고 있어 홈 네트워크 내에 복수의 서버가 있을 경우 사용자의 편의성이 상대적으로 약하다. 이에 본 논문은 홈 네트워크 내에서 콘텐츠 리스트를 통합 관리할 수 있는 Contents List Aggregation 서비스를 제안한다. 제안되는 서비스는 홈 네트워크 내의 미디어 서버들로부터 Contents List를 전송받아 통합된 형태로 저장 및 관리할 수 있으며, 기존 서비스와 호환성을 유지할 수 있다. 서비스의 제안과 함께 서비스를 지원하는 UPnP Device 및 Control Point의 서비스 시나리오, 그리고 서비스 연동에 대한 운용환경 및 사용예가 함께 제시되었다.

This study aimed at making a way of securing the access by using PCA. We got our result through using Box-Plot and PCA with the access data of the area of security level A~E at K(IPS)center. In order to perform PCA, We confirmed the extracted value of commonality has no problem in performing PCA because VIF is below 2.902. Based on this result, We classified people into Green-list, Blue-list, Red-list, and Black-list in a standard of security level with 1.453, as the eigen value of 1 main element, 1.283, as eigen value of 2 main elementm, 1.142, as the eigen value of 3 main element.

In this paper, we propose a system that can analyze appearance interval of casts by detecting and recognizing casts in broadcasting videos. The cast is one of the most important characteristics in broadcasting videos such as drama and sports. In this paper, we propose the ACAV(Automatic Cast-list Analysis in Videos) system that analyzes cast-list automatically in video. The ACAV system consists of FAGIS(FAce reGIStration) which registers detected faces into the face DB and FACOG(FAce reCOGnition) that analyses the cast-list in video sequence using the face DB. We evaluate performance of the ACAV system by comparing with FaceIt, one of the most well-known commercial systems for the cast-list analysis. The ACAV shows face detection and recognition rates of 84.3% and 75.7% that are about 30% and 27.5% higher than those of FaceIt, respectively. The ACAV system can be applied to mass broadcasting videos management system for broadcasters and video management system of PVR(Personal Video Recorder) and mobile phone for the public.

It is essential to effectively manage facilities because operating and maintenance cost for them accounts for more than 83% of lifecycle cost. This study developed BIM Object-based classification list to manage information required to operating and maintenance phase of them from design and construction phase. In order to develop this classification list, Construction Information Classification System, Design Criteria for Architectural Electrical Installations, commodity list classification of PPS(Public Procurement Service) were analyzed. and problems for consisting of object classification list were drawn. And each materials is classified that drawings discipline code (KSF 1540:2010 (Principle and criteria for CAD Drawing) was classified as level 1 to cover main areas and construction information classification system was classified as level 2 to cover elements also UNSPSC was classified as level 3 to cover objects for devices and equipments. this classification criteria was given code. This study is expected to be useful to exchange and share information in operating and maintenance phase by offering object point of view classification in design and construction phase. besides, it is looking forward to effective operating and maintenance of facilities by enabling management of devices and equipments by function, space, use.

Invasive alien species are considered to be one of the main factors that cause biodiversity loss. Establishment of management strategies through continuous monitoring and risk assessment is a key element for invasive alien species management policy. In the present study, we introduce examples of ecological risk assessment tools developed in Japan, Germany-Austria and Belgium. Invasive alien species have been designated in Japan based on the assessment of risks to ecosystems, human health and primary industry. German-Austrian Black List Information System categorized alien species into Black List, White List and Grey List according to their risks to biodiversity. In the Harmonia Information System developed in Belgium, invasiveness, adverse impacts on native species and ecosystem functions and invasion stages were assessed and alien species were categorized into Black List, Watch List and Alert List. These international risk assessment tools may be helpful to improve our national risk assessment protocol for the prioritization of invasive alien species management.

There are many research results for the location update cost minimization of location management in cellular networks. For minimizing the location update cost, we have to take in consideration of each users' mobility pattern. This paper suggests location area list generation and a 3-step paging method based on users' movement history with the users' profiles. Users' mobility has not only geographical regular patterns but also time-related regularity. So, the method extracts users' movement regularities in both geography and time from their movement history, and generate location area list considering the regularities. For the performance analysis of the suggested method, we have executed a simulation for suggested method with user's mobility model. The results of the simulation show that suggested algorithm has some merits in the location management cost.

The rise of music resources has led to a parallel rise in the need to manage thousands of songs on user devices. So users are tend to build play-list for manage songs. However the manual selection of songs for creating play-list is bothersome task. This paper proposes an auto play-list recommendation system considering user's context of use and preference. This system has two separate systems: mood and emotion classification system and music recommendation system. Users need to choose just one seed song for reflection their context of use and preference. The system recommends songs before the current song ends in order to fill up user play-list. User also can remove unsatisfied songs from recommended song list to adapt user preferences of the system for the next recommendation precess. The generated play-lists show well defined mood and emotion of music and provide songs that user preferences are reflected.

To secure superiority in keen competition among ports and to satisfy demands of shippers and shipping companies who are a main customer of ports, logistics service should be improved. However, most of dissatisfaction for logistics service arises from frequent transportation changes of shippers and inaccuracy of cargo-working information offered from shipping companies and inaccuracy of cargo information carried in from carriers. Therefore, the study embodied BPR and yard management prototype system on the basis of the process of business flow in yard to settle the above problems. The study also checked that information of booking list in a yard-allocated plan could be applied to forming efficient collaborative supply networking in yard management by supplementing insufficient cargo.
