In South Korea, the conflict between development and conservation policy still exist among government ministries, and conventional development plan often has priority over conservation policy. Establishment of sustainable development and comprehensive management policy employing the results of ecosystem service studies are highly warranted, but researchers in South Korea are still limited and often misuse the concept of ecosystem services. Thus, we aimed to introduce the concept of Ecosystem Service (ES) and related terminologies such as Social-Ecological Systems (SESs), ecosystem function, trade-off, and human well-being in this paper. Additionally, this article reviewed and arranged key approaches in ES studies as follows: 1) field works, 2) mapping ecosystem services, 3) valuing ES, 4) quantifying trade-offs between ES and 5) understanding SESs. Based on those results, we suggest that field works for basic information have the first priority to be conducted among ES studies. Once basic information is sufficiently accumulated, researchers can perform applied ES research with accuracy. Finally, results of ES studies conducted by five approaches allow decision makers to consider both natural system and society simultaneously, and hence the results can be utilized for sustainable development and conservation policy based on ecosystem-based management.

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.

As we go about our daily lives, people often collect surrounding information and adapt to the situation. Computer development trends show that one wants computers to work like human beings, i.e. computers can sense its context and adapt corresponding to context changes. To implement this expectation, a context aware service layer is needed. In this layer, sensors capture its environment and send this information to the service center. Considering received information as its context, the service center seeks the suitable operation according to the context. Tills paper presents a context aware service which is applied in controlling air-conditioner. The air-conditioner includes sensors which are installed at some special positions in a room. Each of these sensors gathers comfort-influenced information like temperature, humidity and sends them to air-conditioner. The air-conditioner adapts its operation to the environment according to the sensed information. To control the air-conditioner effectively, we use a genetic algorithm which is suitable in adaptation issues. The simulation shows that the room condition can be maintained at a comfortable level by using context-aware services in the operation of the air-conditioning system.

U-City 기반시설의 구성요소는 지능화된 시설, 정보통신망, 통합운영센터로 구분되며, 기존 연구에서의 U-City기반시설은 효율적인 운영 관리의 필요성을 제시하고 있다. 그러나 그 중 법에서 정의하는 내용과 다르게 해석하는 경우가 지능화된 시설에서 빈번히 발생하고 있다. 이러한 문제의식을 토대로 국내 지능화시설 관련 법제도 및 운영관리의 문제점 등을 종합적으로 분석하여 지능화시설의 효율적 활용을 위한 통합운영방안을 마련하고자 한다. 이를 위해 관련 법제도와 실무담당자 인터뷰를 통해 지능화시설의 현황 및 문제점을 파악하고, 지능화 시설에서 생성된 도시정보 및 설치위치를 모두 포함한 통합 활용의 필요성을 도출하였다. 현재 정부부처 및 지자체는 ICT를 활용한 다양한 정보시스템을 구축 운영하고 U-City법에서는 통합적 관리 운영을 명시하고 있으나, 시설 운영주체에 대한 구체적인 책임과 권한에 관한 정의는 명확히 이루어지지 않고 있다. 이를 효율적으로 운영하기 위해 설치된 장비와 여기서 생성된 도시정보를 공동으로 활용할 수 있는 관련 부서 간 원활한 조정이 가능한 추진체계가 필요하다. 본 연구는 지능화시설의 관련법 및 법규들에 대한 논리적 연계의 관계를 정립하여 효율적인 지능화시설 설치 및 관리를 위해 일원화된 법적 시스템의 체계를 마련하고자 한다. 이를 통해 지능화시설의 통합연계 및 활용을 위한 관리체계의 기초 토대가 될 수 있을 것으로 기대한다.
