Robots equipped with artificial intelligence technology include learning functions. Purely inductive learning methods formulate general hypotheses by finding empirical regularities over the trainning examples. Purely analytical methods use prior knowledge to derive general hypotheses deductively. Therefore, when the physical environment of a robot is complex, there is a problem of increased computational time required for information processing. In particular, when a large number of robots transmit information, more computational time is required for information processing. The distance-based topological method proposed in this paper first constructs the topology based on the distances between robots, and then generates information weights according to the stages of the topology. The technique proposed in this paper has been experimentally confirmed to have excellent performance in environments with a large number of robots and complex physical conditions.

PURPOSES : This study defines private and public service providers connected to a public data hub in a smart city and examines the information that should be exchanged between them. The information exchange scheme covers data exchange at a minimum level. METHODS : First, we reviewed the entities participating in the emergency charging service and designed the scope of information linkages between the entities. Second, we diagnosed the main information linkages according to a service flowchart. Third, we reviewed the basic information requirements linked to actors participating in the service. Finally, we derived and presented information linked to the subjects. RESULTS : In addition to the basic requirements, the number of data-exchange information sets specified was four, which was the scope of the aforementioned study. We defined and analyzed an efficient information exchange system between various actors involved in emergency charging services. Data were defined based on interactions between service users, operators, providers, and data hubs. Each set had a different scope and purpose. CONCLUSIONS : Information collected and provided by emergency charging service providers in connection with a data hub that manages urban energy was proposed.

대규모·융복합적 결합은 물론 글로벌 경쟁산업사회에서 현대의 기업경영은 그 엄중함으로 인해 건전하고 투명한 경영을 피할 수 없게 되었다. 예전과 같이 설비투자에 의한 생산과 업적 확대에 초점을 두고 기업을 둘러싼 각종의 리스 크(위험)에 대한 준비를 소홀히(적당히) 하는 것을 허용하지 않는 시점에 있다. 어떠한 원인에 의하건 기업이 사고·재해 그 밖의 부정사건에 휘말리게 되면 해 당 기업에 미치는 손실은 경영 위기로 연결되며, 나아가서는 기업의 지속가능성 을 불가능하게 하고, 기업구성원인 주주를 비롯한 투자자, 소비자, 지역사회 등 광범위하게 걸쳐있는 다양한 이해관계자에게까지 상당한 마이너스 영향을 미치 게 된다. 기업을 둘러싼 리스크는 상당히 다양하고 대규모적인 경향을 띠는데, 기업의 경영활동과 관련해서는 소비자를 비롯하여 기업과 관계를 맺는 다양한 관계자 들이 존재하고 있다. 최근 기업의 경영활동은 다양한 정보를 수집·활용하여 대 규모의 이익을 창출하는 근원이 되고 있지만, 개인정보에 관한 데이터보호문제· 위험관리가 철저하게 이루어져야 함에도 불구하고 그 관리 소홀로 인해 그 개 인정보가 유출되어 커다란 사회적 문제로 부각되고 있다. 한편, 안전관리를 최 우선으로 해야 하는 사업장에서 발생되는 근로자의 안전문제(S), 제조업을 영위 하는 기업의 경우 폐기물·리사이클문제, 화학물질의 유해성문제 및 그로 인한 기후변동의 위험성까지 초래될 염려가 있는 지구환경(E)과 같은 문제는 글로벌 적 차원에서 엄중하게 대응할 문제로 지적되고 있다. 또한 기업지배구조 상 이 사회의 다양성·경영진의 보수·소유구조에 관한 문제(G) 등, 이른바 ESG경영에 있어서의 문제로 이해되면서 이러한 내용에 관한 관심 또한 집중되고 있다. 상장회사에는 주주 이외에도 중요한 이해관계자가 광범위하게 존재한다. 상 장회사는 스스로의 지속적인 성장과 중장기적인 기업가치의 창출을 달성하려면 이러한 이해관계자와 적절한 조화관계를 이룰 필요가 있다는 점을 충분히 인식 해야 한다. 특히 글로벌적으로 사회·환경문제 등에 대한 관심이 증대되고 있는 현 상황을 고려하면 이른바 ESG문제에 적극적·능동적으로 대응할 필요가 있음 은 두말할 필요도 없다.

Big data technology is being used in various fields followed by the development of information and communication technology. In the corporate and public sectors, diverse system platforms are built and operated due to the needs of users, but efficiency is low because they are built from an individual service perspective rather than an integrated service perspective. In this study, the relationship between presenting the characteristics of the type of shared information platform, the integration plan, and integration performance of the shared information system platform was analyzed. The results of the study will provide guidelines for the integration of shared information system platforms by the government and private companies in the future.

The preliminary study was conducted on the use of navigation instruments and programs conducted in the previous demonstration and experiment of the training ship SAEBADA, real-time sharing and accuracy of land and sea information, and the development of real-time effective information transmission and reception and management system programs. Based on this, this study used the training ship CHAMBADA, which is similar in length to the tonnage of the fishing boat. The purpose is to present errors in ship situation-specific information data, alarm systems for marine information, and land and ship transmission and reception programs collected using intelligent information management systems to find out whether they can be applied and used in fishing boats. It plans to conduct research on direct and indirect safety and ship’s stability when the intelligent information management system operates in real time in the operation of ships considering the characteristics of small fishing boats and the characteristics of fishing.

The need for an intelligent information-based ship accident prevention and control system for various marine accidents is very clearly emerging. As it is a variety of marine accidents, the causes are diverse. Therefore, it can be said that it is very important to prevent these marine accidents and their causes in advance. Therefore, a study was conducted on an intelligent information-based ship safety management decision support system that provides information necessary for decision-making at sea and land through an integrated management device for ships that informs safety-related risks in real-time ship operation. In the future, we intend to pursue the development of a system that can aim for safer and more economical ship operation by linking it to navigation instruments through the evaluation and analysis of AI, IoT, and big data.

통합항해시스템(INS)은 기존 항해 장비들을 통합하여 부가가치를 제공하는 장치로써 항해 업무 수행을 위한 정보와 기능을 다기능표시장치에(MFD)에 통합하는 것으로 정의된다. IMO 성능 기준은 각 업무에 대한 최소 요구사항을 명시하고 있지만, 장비 및 기 능의 목록은 정의하지 않아 제조사마다 INS의 구성이 상이하고 사용자 관점에 기반 한 지침 또한 부족한 실정이다. 본 연구는 선박 운 용상황 및 수행 업무에 따라 사용자가 요구하는 정보를 분석하고, 이를 INS의 MFD에 효과적으로 구조화하여 INS의 사용성을 높이기 위해 수행되었다. INS 관련 국제 기준 및 제조사의 구성 장비 목록을 분석하여 필수 항해 정보들을 선별하고 MFD 사용 경험이 있는 선박 운항자를 대상으로 카드 소팅 테스트를 실시하여 각 INS 업무에 요구되는 정보들을 분류하도록 하였다. 연구의 결과는 제조사들 이 제품 설계 시 사용자 경험을 반영한 정보 구성에 기본적인 가이드로 활용될 수 있을 것이다.

An ecological niche is defined as the specific role of a species influenced by time, space, and other resources. By investigating overlaps between ecological niches of different species, we could estimate the degrees of interspecific competition. Such studies often use geographic information systems (GIS) to discover niche overlaps between species. In this study, we used GIS to estimate the spatial niches of two Korean frog species (Pelophylax nigromaculatus and P. chosenicus). This enabled us to predict their geographic distributions in order to identify their coexistence regions and distribution patterns. The results confirmed that altitude was an important variable for predicting their distribution, with a correlation with their climatic range. Spatial distributions of the two frog species were highly overlapped, as the distribution range for P. nigromaculatus included most of the range of P. chosenicus, showing a sympatric distribution pattern. Within the coexisting regions, however, the presence sites for the two species did not overlap, implying weak competition. To confirm the principal factors influencing their competitive relationship and reasons for their sympatric distribution pattern, we need more detailed in-depth studies on the diverse environmental variables within the regions where the two species coexist. By doing so, we would be able to identify various mechanisms for avoiding competition in sympatric frog species.

With the advent of the 4.0 era of logistics due to the Fourth Industrial Revolution, infrastructures have been built to receive the same services online and offline. Logistics services affected by logistics 4.0 and IT technology are rapidly changing. Logistics services are developing using technologies such as big data, artificial intelligence, blockchain, Internet of things, and augmented reality. The convergence of logistics services and various IT new technologies is accelerating, and the development of data management solution technology has led to the emergence of electronic cargo waybill to replace paper cargo waybill. The electronic waybill was developed to supplement paper waybill that lack economical and safety. However, the electronic waybill that appeared to complement the paper waybill are also in need of complementation in terms of efficiency and reliability. New research is needed to ensure that electronic cargo waybill gain the trust of users and are actively utilized. To solve this problem, electronic cargo waybill that combine blockchain technology are being developed. This study aims to improve the reliability, operational efficiency and safety of blockchain electronic cargo waybill. The purpose of this study is to analyze the blockchain-based electronic cargo waybill system and to derive evaluation indicators for system supplementation.
