  • For forest fire monitoring in relatively cool area like Siberia, design of Decision Support System (DSS) is proposed. The DSS is consisted of three different algorithms to detect potential fires from NOAA AVHRR image. The algorithm developed by CCRS (Canada Center for Remote Sensing) uses fixed thresholds for multi-channel information like one by ESA (European Space Agency). The algorithm of IGBP (International Geosphere Biosphere Program) involves contextual information in deriving fire pixels. CCRS and IGBP algorithms are rather liberal compared to more conservative ESA algorithm. Fire pixel information from the three algorithms is presented to the user. The user considers all these information in making decision about the location fire takes place.

  • Planting intercropping in rubber plantations is another alternative for generating more income for farmers. However, farmers still lack the knowledge of choosing plants. In addition, information for decision making comes from many sources and is knowledge accumulated by the expert. Therefore, this research aims to create a decision support system for growing rubber trees for individual farmers. It aims to get the highest income and the lowest cost by using semantic web technology so that farmers can access knowledge at all times and reduce the risk of growing crops, and also support the decision supporting system (DSS) to be more intelligent. The integrated intercropping ontology and rule are a part of the decision-making process for selecting plants that is suitable for individual rubber plots. A list of suitable plants is important for decision variables in the allocation of planting areas for each type of plant for multiple purposes. This article presents designing and developing the intercropping ontology for DSS which defines a class based on the principle of intercropping in rubber plantations. It is grouped according to the characteristics and condition of the area of the farmer as a concept of the rubber plantation. It consists of the age of rubber tree, spacing between rows of rubber trees, and water sources for use in agriculture and soil group, including slope, drainage, depth of soil, etc. The use of ontology for recommended plants suitable for individual farmers makes a contribution to the knowledge management field. Besides being useful in DSS by offering options with accuracy, it also reduces the complexity of the problem by reducing decision variables and condition variables in the multi-objective optimization model of DSS.

  • Deep-sea bacteria are adapted to extreme environments, such as high pressures and cold temperatures. We have isolated many piezophiles which grow well even under high pressures from deep-sea sediment. Shewanella violacea DSS12 and Moritella japonica DSK1 have the ability to grow at up to 70 MPa, and those bacteria have unique mechanisms of gene expression in response to high pressure conditions. The combination of gene expression systems in piezophiles, like the high pressure-dependent promoters and GFP reporter gene, may reveal highly fluorescent cells when exposed to high hydrostatic pressure conditions. It is predicted that a novel bio-sensing system can be made to probe high pressure environments using living bacteria. First, gene transformation into our piezophiles, strains DSS12 and DSK1, were examined. Eschericha coli S17-1 was used for bacterial conjugation with those piezophiles. As a result, the broad host range vector, pKT231, and the shuttle vector, pTH10, were successfully introduced to DSS12 and DSK1, respectively. Next, The pressure regulated promoters from DSS12 and DSK1 were cloned into proper vectors and combined with GFP as a reporter gene downstream of each promoter. The transformants of DSK1 and DSS12 with the recombinant pTH10 and pKT231 plasmid, which has cadA and glnA promoters (each of them is a pressure regulated promoter from DSK1 and DSS12, respectively) and GFP, were grown under high pressure and gene expression of GFP promoted by 50 MPa pressure was confirmed. This is a critical point to create a pressure-sensing bacteria, as the "High Pressure Glow Cells", which will indicate the level of environmental pressure using fluorescence of GFP as a reporter gene.

  • 5G 서비스는 기존 이동통신주파수보다 상대적으로 높은 중대역(n78)을 사용하고 있어서 2GHz 이하의 저대역 주파수를 활용하여 5G 커버리지 개선이 필요하다. 이를 위해서는 저대역 주파수의 대부분을 사용하는 LTE와 5G-NR 시스템의 동적 스펙트럼 공유(Dynamic Spectrum Sharing) 기술의 적용이 요구된다. 본 논문에서는 DSS 적용을 위한 시그널링 오버헤드 요소와 단말기 구현 RF 이슈들을 도출하고, 저대역 주파수 중 광대역 주파수 활용이 가능한 1.8GHz 대역(50MHz 폭)에 대해 5G-NR과 LTE 각각의 관점에서 시그널링 오버헤드 비율과 단말기 RF 이슈들을 분석하였다. 분석 결과들을 통해 저대역을 활용한 DSS 기술을 적용한다면 LTE 트래픽이 5G-NR로 빠르게 이전할 경우, 5G 커버리지 개선으로 인해 우수한 서비스 품질을 제공할 수 있을 것으로 예상된다.

  • This paper is concerned with designing and implementing the Internet shopping mall by using virtual reality-driven avatar and web decision support system. Traditionally, the Internet shopping mall has been designed based on the combination of several hyperlinks, images, and texts. However, this sort of approach results in a lower performance because possible customers cannot make more accurate shopping decisions. To overcome this kind of pitfalls facing the current Internet shopping malls, we propose using a combination of virtual reality and web DSS. The main virtues of our proposed approach to designing the Internet shopping mall are as follows: First, the virtual reality technique is emerging as one of alternative guaranteeing a sense of reality for customers part and facilitating the complex process of shopping decision makings. Especially, the avatar, which is an artificially designed man working on the Internet, can make easy and absorbing the Internet shopping-related decision making processes. Second, the web DSS approach can provide an effective decision support mechanism for customers. Especially, we design a set of intelligent agents for the proposed web DSS. Experimental results with an illustrative example showed that our proposed approach can yield a new Internet shopping mall paradigm with which customers can benefit from a high level of decision support functions.

  • To develop a watershed management plan for protection of the lake water quality, the linkages among land use activities, stream water quality, and lake water quality must be understood. This study conducted to develop a Decision Support System(DSS) for the reservoir water quality managers and a comprehensive watershed management plan. This DSS has three main components; database, interactive decision model, and data delivery interface system. Graphic User Interface(GUI) was developed as the interface medium to deliver the data and modeling results to the end users. Water quality management scenarios in Yongdam reservoir consist of two parts. One is the watershed management, and the other is water quality management in the reservoir. The watershed management scenarios that were evaluated include as follows : a removal of point sources, control of waste water treatment plant, reductions in nonpoint sources, and the management of developed land. Water quality management scenarios in the reservoir include to install a curtain wall and to operate an algae removal system. The results from the scenario analysis indicate that the strategy of the reservoir water quality management can promise the best effectiveness to conserve the quality of reservoir water. It is expected that many local agencies can use this DSS to analyze the impact of landuse changes and activities on the reservoir watershed and can benefit from making watershed management decisions.

  • 본 연구에서는 유비쿼터스 환경에서 시시각각으로 변하는 고객의 요구사항을 만족시키기 위해 상호 협력을 시도하는 다중 에이전트들이 의사결정을 수행할 경우 발생할 수 있는 충돌의 해결을 지원하는 지능적인 온톨로지 관리 모듈(intelligent-Ontology Management Module, i-OMM)과 다중에이전트 관리 모듈(Multi-agent Coordination Module, MACM)을 포함하는 u-DSS 포털을 제안한다. 개별 에이전트들은 온톨로지와 문제해결을 위한 프로시저 등을 이용해 자신의 문제를 해결하는 것을 기본으로 한다. 그러나 다른 에이전트들과 협력을 통해 문제를 해결해야 할 경우에는 먼저 개별 에이전트들이 보유한 각 온톨로지의 통합 및 데이터간의 충돌 해결이 요구된다. i-OMM은 개별 에이전트들이 보유하고 있는 이질적인 온톨로지를 통합하여, 문제해결을 위한 하나의 통합된 새로운 동적 온톨로지 뷰(integrated ontology view, IOV)의 생성을 지원한다. 온톨로지 통합과제에서 생성된 IOV는 사례로 저장되고 유사한 문제 해결에 재사용된다. MACM은 고객 에이전트들의 요구사항 변화에 따라 관련 개별 에이전트들 간의 데이터 충돌을 해결하여 에이전트들의 의사결정과정을 지원한다. 따라서 i-OMM과 MACM을 이용한 유비쿼터스 컴퓨팅 환경에서 분산된 에이전트들의 협력적 문제 해결을 지원하는 시스템을 유비쿼터스 의사결정지원 시스템 포탈(ubiquitous decision support system, u-DSS Portal)이라고 지칭한다. 본 연구에서 제안된 알고리즘의 활용 대상은 고객, 판매자, 제조업체, 및 배송업체의 배송차량들의 에이전트들로 구성된 u-fulfillment 시스템으로 한다.
