에너지 공급기반이 취약한 일본에서 에너지의 이용효율 향상과 에너지 절약의 촉진은 중요한 과제의 하나이다. 이를 위하여 일본 정부는 1997년 4월 ''종합에너지대책 추진 각료회의''에서 자에너지의 추진과 전력공급의 안정 및 공급설비의 증대 억제에 의한 전력공급코스트의 저감을 위하여 전력부하 평준화의 추진을 결정하였다. 이것에 이어 ''97년 7월에는 ''전력부하평준화대책검토위원회''가 발족되고 12월에는 중간보고로서, ''전력코스트삭감=축열공조(저온도 포함) 보급확대''가 제안되어 거국적인 축열 보급확대의 필요성이 인식되게 되었다. 빙축열 공조시스템은 주간 전력소비를 억제하고 야간전력을 사용함으로써 탄산가스 배출을 삭감하는 효과도 기대되고 있어, 앞으로 일본 국내 공조시스템의 일익을 담당하며 국가에 의한 지원도 받아 급속한 시장침투가 확대될 것으로 전망되고 있다. 미쓰비시전기에서는 타사에 앞서서 선진적인 빙축열 공조시스템을 제작$\cdot$판매하고 있으며 업계의 선도적 위치를 유지하고 있다.

전편의 실험적 연구에 이어서, 기 수행된 4개의 외부 접합부 시험체에 현존하는 여러 강도 예측식을 사용하여 콘크리트 기둥-강재 보 접합부의 내진 성능을 결정하는 패널 전단 및 지압 강도를 평가하였다. 또한, 접합부 패널지역의 변형특성을 묘사할 수 있는 일련의 스프링을 사용한 macro 형태의 해석모델이 논의되었으며, 이에 따라 Drain-2DX 및 IDARC 등의 상용프로그램을 사용하여 접합부의 패널전단 및 지압 파괴형태의 변형을 포함하는 단순해석이 수행되었다. 강도 예측결과에 의하면 본 연구에서 제시하는 수정된 내부 콘크리트 패널 전단 강도식을 포함하고 있는 ASCE 방법이 실험결과에 가장 근접한 것으로 나타났으며, 본 연구에서 검토된 패널지역 변형을 고려한 단순해석모델은 향후 전체 건물해석에 사용할수 있는 것으로 판단되었다.

Digital game includes one more funny elements which are competition, puzzle, interaction and role-playing. These elements encourage the player's interest and flow. The purpose of this study is to find out the essence of these elements in digital games with Cannibalism. Digital game inherits and develops Cannibalism in the digital space as magic circle, death and rebirth of life, changing the shape of character and reversing the interface.

태블릿 PC의 등장, 미디어 기기의 소형화, 스마트 폰의 등장과 맞물려 기존의 동영상 및 음성을 통한 교육 콘텐츠시장이 크게 확대되어 가고 있다. 특히 어학 콘텐츠의 경우 구간 반복을 통한 내용 전달이 필수적이어서 많은 미디어 플레이어는 사용자가 직접 설정한 구간을 반복 시청할 수 있도록 하는 기능을 포함하고 있다. 본 논문은 기존의 구간 반복 기능에서 한 단계 나아가 사용자의 수동 조작없이 미디어 플레이어가 자동적으로 문장을 감지하여 해당 문장을 반복하는 Player chop를 소개한다. Player chop 는 영상 파일에서 추출된 모든 문장의 시작과 종료 지점에 대한 시간 정보를 목록화 하여 손쉽게 반복 재생이 가능하도록 하였으며, 목록화 된 시간 정보를 바탕으로 자막을 연동하여 사용자의 외국어 학습에 도움이 될 수 있도록 하였다.

Phytoplankton community structure and distribution pattern in the surface water around the Ieodo Ocean Research Station were investigated during seven cruises carried out from July, 2003 to October, 2004. Samples were analyzed using various tools including a microscope, flow cytometer, and HPLC. Satellite images were used to analyze spatio-temporal phytoplankton biomass distribution. SeaWiFS chlorophyll a (chl a) images showed that spring blooms occurred in April-May near the Ieodo Station, and these waters were under the influence of Changjiang Dilute Water during July-October. Also, during the July-October period, HPLC pigments data showed increasing zeaxanthin concentrations, a marker pigment of cyanobacteria whereas increasing concentrations of various other pigments such as fucoxanthin, peridinin, prasinoxanthia alloxanthin, 19'-hexanoyloxyfucoxanthin and chlorophyll b were noted during spring blooms. Such pigment marker data were consistent with picoplankton data analyzed by flow cytometer and nano-microplankton analyzed by microscope. The pigment-CHEMTAX method was used to drive the phytoplankton group apportioned chi a. Diatoms, chlorophytes, dinoflagellates, and cryptophytes comprised 25.8, 20.7, 15.9, and 14.1%, respectively, of the total chl a in May. Average cyanobacteria concentrations in July-October contributed 25.4% of the total concentration. This was the highest percent contribution and was followed by chlorophytes, diatoms, and prymnesiophytes. This study discusses results from various methods, similarities and differences in the results among those methods, and the application range of the results from different analytical methods. Also, the study reveals a detailed phytolpankton community structure in the waters around the Ieodo Station, and suggests future monitoring considerations in relation to cell morphology, ecology and diversity factors according to taxonomic groups.

In this paper, we propose subregion-based area of interest management techniques for MMORPG(massively multiplayer online role playing games) integrating P2P(peer-to-peer) networking and cloud computing. For the crowded region, the proposed techniques partition it into several subregions and assign a player to manage each subregion as a coordinator. These techniques include a load balancing mechanism which regulates communication and computation overhead of such player below the specified threshold. We also provide a mechanism for satisfying the criterion, where subregions overlapped with each player's view must be switched quickly and seamlessly as the view moves around in the game world. In the proposed techniques where an efficient provisioning of resources is realized, they relieve a lot of computational power and network traffic, the load on the servers in the cloud by exploiting the capacity of the players effectively. Simulation results show that the MMORPG based on cloud and P2P architecture can reduce the considerable bandwidth at the server compared to the client server architecture as the available resources grow with the number of players in crowding or hotspots.

User activity log includes lots of hidden information, however it is not structured and too massive to process data, so there are lots of parts uncovered yet. Especially, it includes time series data. We can reveal lots of parts using it. But we cannot use log data directly to analyze users' behaviors. In order to analyze user activity model, it needs transformation process through extra framework. Due to these things, we need to figure out user activity model analysis framework first and access to data. In this paper, we suggest a novel framework model in order to analyze user activity model effectively. This model includes MapReduce process for analyzing massive data quickly in the distributed environment and data architecture design for analyzing user activity model. Also we explained data model in detail based on real online service log design. Through this process, we describe which analysis model is fit for specific data model. It raises understanding of processing massive log and designing analysis model.

The Sydney Opera House is built on a peninsula of rock that juts out into Sydney Harbor. The site was once a landing place for ships. Utzon, Architect, designed the theatres for the Opera House to fit the shape. The two theatres were placed side by side so that they both had extensive harbor views. The Sydney Opera House is designed the foyers to take full advantage of these sights. Because the building would be seen from all sides, even from above, it was to be a piece of sculpture. The outside was as important as the inside. The audience enters from behind the stage and walks around to the foyers overlooking the harbour. The wing and backstage areas are small because of the way the foyers wrap around the theatre. The stage is made up of large platform lifts which provide the vertical movement for changing scenery. The sets come up from the workshops below stage. The flytower fits under the largest roof shell and doesn't break the skyline. The important elements are the podium, the shells and the reminders. The podium, the huge monolithic concrete structure, contains hundreds of rooms and nearly all the technical equipment. The podium is clad with pink granite slabs and seen from the water. This design eliminated a maze of fire escape stairs and, at the same time, gave people a wonderful view of the harbour. The egg shell is remarkably strong and express the form as the symbol of the site.

This study aims to analyze the system of official documents enacted during the modern reform period and the official documents produced in the provincial government office, scrutinizing the reality of management of the official documents that were conducted in the provincial government office at that time and organizing the characteristics. For this, I progressed this study targeting Changwon superintendent office that functioned as the modern government office among the provincial government office that existed during the modern reform period, and whose official documents produced in the government office remained relatively intact. At first, I summarized the history of Changwon area where Changwon superintendent office was installed. I investigated the geographical characteristics and the historical background in which Masanpo port of Changwon was opened in the past history and the superintendent office was installed. Following this, I categorized the function of Changwon superintendent office from the legal perspective, and reviewed the major contents of the official documents produced in the business activity and the historical context. Finally, I compared and analyzed the system of the official documents enacted at that time and their formats, organizing the official documents produced in the provincial government office during the modern reform period and the characteristics of the system of the official documents about the provincial government office.
