Uigwe is official reports of the Joseon dynasty. They published from early Joseon but remain from 17C. We can search many hidden informations in them. Ga-Jungjagak (temporary T-shaped house) is one of them. It is unique architecture of the Joseon dynasty but it doesn't exist now at all. We can see many drawings describing Ga-Jungjagak (temporary T-shaped house) located next to Jungjagak in Uigwe. Jungjagak (T-shaped house) was built in royal tombs for sacrifice. Ga-Jungjagak was built in royal tombs for sacrifice as Jungjagak but existed temporarily. In this study, I want to find the process of norms Ga-Jungjagak in old records, official reports and annals of the Joseon Dynasty. Results are as follows: Ga-Jungjagak is the sacrifice space for queens in royal tombs. It is need to avoid sacrifice of delight and sorrow at the same time. They sacrifice to represent sorrow after the death of kings and queens for three years. After three year, they sacrifice to represent delight for kings and queens became ancestral gods. Ga-Jungjagak was destroyed three years later to combined sacrifices. The shape of Ga-Jungjagak is similar to Jungjagak in the same tomb. But dimensions of Ga-Jungjagak are equal or smaller than Jungjagak and decorations are abstemious.

4K 초고속 카메라 촬영은 해상도 및 셔터스피드 증가로 인해 빠른 피사체의 영상을 모션 블러 없이 Full HD 4배 해상도로 촬영이 가능하다. 그러나 해당 촬영은 데이터 량의 증가와 광량, 포커스 등 여러가지 제약사항이 뒤따른다. 증가된 셔터스피드로 인해 광량 부족 현상을 가져올 수 있어 조리개를 개방하여 촬영하는 경우가 많아 초점 조절에 제약이 따른다. 또한 증가된 해상도와 프레임레이트로 인해 저장 공간의 한계가 뒤따르기 때문에 촬영 기록에 제한이 따르고 있다. 따라서 본 연구는 4K 초고속 카메라(Phantom Flex 4K) 제작 사례를 통해 위와 같은 한계점들에 대해 분석하고, 이를 극복하기 위한 효율적인 워크플로우를 디자인 하였다.

Recently, user-created video shows high increasing in production and consumption. Among these, videos records an identical subject in limited space with multi-view are coming out. Occurring main reason of this kind of video is popularization of portable camera and mobile web environment. Multi-view has studied in visually representation technique fields for point of view. Definition of multi-view has been expanded and applied to various contents authoring lately. To make user-created videos into multi-view contents can be a kind of suggestion as a user experience for new form of video consumption. In this paper, we show the possibility to make user-created videos into multi-view video content through analyzing multi-view video contents even there exist attribute differentiations. To understanding definition and attribution of multi-view classified and analyzed existing multi-view contents. To solve time axis arranging problem occurred in multi-view processing proposed audio matching method. Audio matching method organize feature extracting and comparing. To extract features is proposed MFCC that is most universally used. Comparing is proposed n by n. We proposed multi-view video contents that can consume arranged user-created video by user selection.

Paper is on defense for so-called internet crisis, the attack of DDoS (Distributed Denial of Service) which was targeted to the central government ministries, financial sector, and portal sites of chief counties including Korea on June 7th, 2009 as its start. By conducting attack with various DDoS attacking methods in the lab environment and dividing networks targeted by the attack by layers, this paper records and analyzes the chief information for attack, destination information of packets, defense policy setting, and the flow of packet attack with the subjects of the networks separated. This study suggests CFC system using multiple firewalls applying defense policy corresponding to the target layer for ultimate attack and tests it according to the result of analyzing the attack packet information and its amount, log analysis, access recording port, and MAC and IT information, etc. by layers. This article is meaningful in that it analyzes the attack by layers, establishes firewall policy for protecting each layer, and secures accurate mechanism for detect and defense.

역사문화 콘텐츠는 사회적 변화 또는 발전에 대한 기록 또는 근거 자료들을 디지털화한 것을 말한다. 사회적 변화 또는 발전은 사회와 자연의 상호작용의 결과라고 할 수 있으며, 관찰자의 시공간적 위치에 따라서도 내용이 달라진다. 따라서 역사문화 콘텐츠는 저장과 보존, 정보의 교환뿐만 아니라 미래의 변화에 대응할 수 있도록 하는 확장된 개념의 상호운용성과 사용자의 요구 또는 상황에 따라 연관된 정보를 쉽게 제공할 수 있도록 하는 지능화된 서비스가 가능한 구조를 갖도록 할 필요가 있다. 본 연구는 사건 또는 스토리의 콘텍스트에 기반으로 사람, 공간을 포함하는 객체들 간의 관계를 설정하는 온톨로지 설계 방법을 제안하고 이를 성서 콘텐츠에 적용하였다.

본 연구는 정적 라우팅과 동적 라우팅의 장점을 활용하여 최단 거리를 산정하는 하이브리드 방식의 라우팅 기법이다. 네트워킹은 휴먼 펙터에 의해 결정이 되기 때문에, 네트워크 트래픽은 항상 특정 시간에 몰리게 되고 네트워크 트레픽 레코드를 분석하면 각 시간대별로 네트워크 트레픽 추측이 가능하다. 따라서 RIP의 잦은 정보 교환으로 인해 발생되는 부하를 줄여 IP 네트워크에서 최단 경로를 산정하는 것이 이 논문이 목적이다.

A 8-year-old, intact male Yorkshire Terrier Dog was presented with dark-black mass on the third digits of the left forelimb. Three months earlier, the dog had experienced an episode of digit amputation because of growing mass with ulcerated nodule of the same area. According to the owner, the recurrence of the mass appeared suddenly and was growing rapidly from the amputation site. The mass was more infiltrative than the first one and measured 1.5 cm in diameter. The clinical signs were anorexia, coughing, respiratory distress, exercise intolerance, cardiac murmurs, and cyanosis on the oral mucous membrane. Plain radiographic findings revealed multiple, various-sized(0.5 to 7 cm in diameter), slightly firm-nodules on the thoracic region but digital bone lysis was not seen. These lesions on the thoracic cavity were considered likely to be metastatic from the digit and the dog was naturally died after 3 weeks from the time. Histologically, the digital mass confirmed the diagnosis of metastatic malignant melanoma that was composed of round melanocytic neoplastic, anaplastic, and melanin-containing cells. This report records clinical information and gross and light microscopic features of metastatic malignant melanoma in a dog.

Currently, the record of part-timer is mainly written in handwriting or using excel work schedule, paper work recorder, and time attendance program using POS program. And, work table, commute records, paycheck are managed separately. Time-attendance information is not linked and is managed separately, and payment of wages is often not done accurately. And, it is difficult to pay the wages because it is not able to accurately grasp the state of attendance of part-timer. Therefore, it is necessary to have a transparent wage and work management system based on the trust between the owner and the part-timer. In this paper, we design a system that can perform real-time commute check using beacon, transparent wage management, wage calculation by automatic calculation, and smooth communication between owner and the part-timer. We have also implemented a store management mobile application using Android Studio 2.3, Eclipse, Android 5.1 and Beacon devices in a MySQL environment.

This study will establish the transformal characteristics of architectural visual information by investigating: how contemporary architects perceive and process multifaceted architectural information via the expression media since 1970s. The purposes and results of this study are summarized as follows: This study established the contemporary transformal characteristics by comparing the expression methods of traditional architects with the transformal characteristics of visual information derived from the contemporary architectural expression media. In a pluralistic information society, the expression methods of the past, which recognize space as a stationary, unidimensional visual point on a drawing surface, is now changing to the mixed, multidimensional expression methods that connect various visual points on a limited drawing surface. Furthermore, the rapid advancement of digital media is changing, from a method which simply arranges visual information, to a flexible visual tool which can process architecture sequentially and simultaneously. As the communication structure of architecture is moving toward an individual-centered two-way communication type, the information delivery method is used to visualize conceptual, inferential information, rather than visualizing realistic information which simply records facts. In the past, multidimensional, non-linear forms could not be processed by the conventional design processes and sketch work, but now they can be expressed via digital media.
