In this study the writer would like to study the art of navigation in the Era of Silla. For the purpose of this study, the writer studied ship's log book of Ennin's Diary, the ancient ship's structures of Korean, Chinese, Japanese, winds and ocean currents around Korean Peninsular which effect the navigation of sailing ship, and ancient reference books and materials. The result of this study. in the ship's structure in the Era of Silla. bottom structure is considered flat and V-Shaped type, and sailing ship had anchor, sail, considerable deckhouse, transverse bulkhead. And the ship's main materials of sailing ship was wood. partially used irons in the panting structures. In the art of navigation, navigators used winds, ocean current, anchor, sail, depth and color of sea water, lights, ballast. Especially navigators used astrologers and geomancers for astronomical observation, weather forecast, natural phenomena.

In this paper, we develop a mobile MAP open API using HTML5 local storage and the W3C geolocation API. The mobile MAP open API consists of the basic JavaScript MAP API, offline navigation API, and multimedia POI (mPOI) API. The basic JavaScript MAP API creates a map and controls, rotates, and overlays data on the map. The offline navigation API is developed using HTML5 local storage and web storage. The mobile web application downloads and stores mPOIs of works of art to local storage or web storage from a web server. The mPOI API is developed using HTML5 video and audio APIs. We develop a mobile art park guidance application using the developed mobile MAP open API.

In this paper, the state-of-the-art IVEF Service based on e-Navigation System was represented. The unification of the data exchange format among maritime-related systems is one of vital user-needs of e-Navigation, advantageous in bringing maritime safety and security. This paper propose the method to exchange marine information in IVEF, as recommended by the IALA, between VTS centers and Korea's GICOMS as well as the government-related agencies. To achieve this, a system data flow was designed which it acts as client and server. It enables the sending and receiving of Radar and CCTV images in accordance with the IVEF recommendation document of IALA.

In the guided missile and unmanned vehicle system, the navigation system is one of the most important components. Recently, low-cost effective smart projectiles and guided bomb are being developed using MEMS based navigation system which has high-G, low-cost and small size. In this paper, locally developed MEMS based GPS/INS integrated navigation system will be introduced in comparison with the state of the art of MEMS based navigation system. And technical design and development method is described to satisfy the required performance of GPS receiver, MEMS inertial sensor assembly, navigation computer and software.

수변공간개발 사례를 중심으로 문화예술을 활용한 도시공간 재생의 의미를 이해해 보고자 한다. 특히 지역문화의 활성화를 핵심적인 의도로 가지는 문화도시전략에서 문화예술의 역할을 해항도시의 수변공간개발에서 문화정책 및 그 실현과정을 통해 고찰한다. 이를 위해 수변공간을 둘러싼 역사적 건축물이나 수변 경관 등 개성적이고 매력 있는 도시경관과 지역자원을 활용하여 문화예술공간 창출을 통한 성공적인 수변공간개발을 진행하고 있는 일본 요코하마를 대상으로 살펴본다. 요코하마는 일본의 '문화예술창조도시' 전략의 일환으로 '창조도시 요코하마'라는 문화정책을 펼치고 있는데, 그 중 공간계획정책이라고 할 수 있는 '내셔널 아트 파크 구상'은 문화예술공간 창출을 통해 수변공간 재생을 실현하고 있다. 이 사업의 기본적 의도와 구체적 실행과정 등을 살펴봄으로써 해항도시의 수변공간개발에서 문화예술이 가지는 역할을 이해하고 수변공간 재생에 있어서 문화정책의 방향성에 대해 검토한다.

오늘날 '컨버전스'와 '소통'은 모든 분야에서 키워드가 되고 있다. 예술가와 공학자는 새로운 기술에 기반을 둔 협업을 통해 그 동안의 상호단절에서 벗어나 점차 소통하고 있다. 컨버전스 시대에 예술 영역의 인터넷 아트와 기술 영역의 내비게이션과 아이폰에서 오감융합기술의 활용이 돋보인다. 소메라와 미뇨노의 인터넷 아트 $\ll$Riding the Net$\gg$, $\ll$The Living Room$\gg$, $\ll$The Living Web$\gg$은 음성인식을 통한 시각이미지와 촉각을 통한 시 공간 표현을 인터넷과 오감융합기술을 통해 구현하고 있다. 그리고 산업기술에서 내비게이션과 아이폰은 음성인식을 통한 오감융합기술을 적용하여 감성영역을 확장하여 인터넷 아트와 비슷한 기술을 선보인다. 이 연구에서 살펴본 바와 같이, 예술과 기술의 융합적 발전은 디지털 아트와 문화기술 산업의 새로운 지평을 열 것으로 보인다.

Robot navigation has seen a major improvement since the the rediscovery of the potential of Artificial Intelligence (AI) and the attention it has garnered in research circles. A notable achievement in the area was Deep Learning (DL) application in computer vision with outstanding daily life applications such as face-recognition, object detection, and more. However, robotics in general still depend on human inputs in certain areas such as localization, navigation, etc. In this paper, we propose a study case of robot navigation based on deep reinforcement technology. We look into the benefits of switching from traditional ROS-based navigation algorithms towards machine learning approaches and methods. We describe the state-of-the-art technology by introducing the concepts of Reinforcement Learning (RL), Deep Learning (DL) and DRL before before focusing on visual navigation based on DRL. The case study preludes further real life deployment in which mobile navigational agent learns to navigate unbeknownst areas.

This paper addresses on the International technical trends, standards, and development status of terrestrial radionavigation system to provide more accurate and fail-safe Positioning, Navigation, and Timing (PNT) Information available in maritime navigation environment. We analyze the performance result of pilot service in enhanced Long range navigation (eLoran) testbed environment using Low Frequency (LF) signal, and describe the development status of Ranging-Mode (R-Mode) system using Medium Frequency (MF) and Very High Frequency (VHF) to meet the Harbor Entrances and Approaches (HEA) requirement of International Maritime Organization (IMO) within 10m position accuracy. Furthermore, we present an architecture for integrated service of satellite-terrestrial navigation system and future maritime applicable fields. As the core information infrastructure of future navigation for 4th industrial revolution, this paper will be contributed to determining the direction of present and future to provide fail-safe PNT service with Global Navigation Satellite System (GNSS) based on the technical enhancement of terrestrial integrated navigation system.
