The computerized management system for bridges is required due to the increased service life and number of bridges. This paper provides information and communication technology (ICT) - based bridge management system (BMS) to enable life cycle management through a comparative study with the development trend and function of domestic and foreign BMSs. BMS developed as an operation system combined an internet and mobile program, and was based on GIS technology and an object-based information management system. BMS supports the establishment of long-term strategies and short-term plans based on predicting the life-cycle performance profile and the necessary budget by object-based informatization for the whole life-cycle information of bridges. Useful knowledge information for supporting decision making was derived from the life-cycle management strategies establishment for approximately 6,000 existing bridges. BMS was developed to be applicable to all nationwide road bridges. In addition, it can be used practically to maintain the performance based on accurate maintenance result management, reducing cost by reasonable budget management, and enhancing the convenience and reliability of field data collection.

전통적인 디지털 박물관 시스템은 전시를 조직화하는 단순한 기능에 촛점을 두고 있으며 설계 패턴은 전시 항목들에 기반을 두고 있다. 이것의 생명주기는 직선적이고 피드백과 재사용성이 부족하여 생명 주기에서 지식 처리를 다루는 것에 대해서는 관심을 가지지 않고 있다. 하지만 현대 디지털 박물관은 급진적으로 증가하는 정보를 다루어야 하고, 디지털 감상, E-학습과 관련 연구를 위해 통합된 기능을 제공해야 한다. 이러한 요구사항들은 디지털 박물관에서 객체들이 고수준으로 추상화되고, 생명주기도 반복적이며 재사용이 가능하도록 요구하고 있다. 그러므로 체계적으로 통합된 지식처리 과정들이 디지털 박물관에서 정보시스템을 다루기 위해서 절대적으로 필요하게 되었다. 본 논문에서는 현대 디지털 박물관 시스템에서 새로운 생명주기를 제안한다. 지식 흐름(knowledge flow)은 디지털 박물관 생명주기에 걸쳐서 모든 정보 흐름으로부터 고수준으로 추상화된 객체이다. 지식 흐름을 따라가게 되면 이 특별한 생명주기는 정의된 시금석으로서 다차원의 분수 모델(Fountain Model)과 비슷하며, 이 생명주기에서 지식처리 과정은 각 차원에서 다른 강조점을 지닌 계층으로 잘 나누어진다. 또한 분산된 지식 처리 절차를 체계적이고 재사용할 수 있도록 통합하기 위한 지식 기반 소프트웨어 공학 접근방법을 제공한다.

Nowadays knowledge is begging to supplant the traditional factors of production and has become the most important new corporate and competitive resource. Many construction firms have been trying to perform Knowledge management, and implement Knowledge Management System. For successful KMS, a company should check the exiting infrastructures which includes resources and knowledge which an organization already may have in place, their culture, and processes and adopt the proper approach according to their own business requirement. This study defined the knowledge life-cycle and proposed management knowledge method of construction field with KMS.

In traditional environments we have called the data life cycle DIKW, which represents data-information-knowledge-wisdom. In big data environments, on the other hand, we call it DIA, which represents data-insight-action. The difference between the two data life cycles results in new architecture of data resource management. In this paper, we study data resource management architecture for big data environments. Especially main components of the architecture are proposed in this paper.

The growing emphasis on knowledge management is given to research institutes whose work processes including R&D are mainly focused on knowledge or technology. It is due to the fact that the system integrating, sharing and generating knowledge serves as the growth engine of those institutes. This study creates the knowledge management framework based on the research process which is the key process in research institutes, and applies to POSCO Research Institute(POSRI) who is a leading institute in this domain. Practical framework and methodology are found in POSRI through systematic operation of knowledge management process.

This paper introduces an approach to an ontology-based knowledge framework for product life cycle management (PLM). Participants in a product life cycle want to share comprehensive product knowledge without any ambiguity and heterogeneity. However, previous knowledge management approaches are limited in providing those aspects. Therefore, we suggest an ontology-based knowledge framework including knowledge maps, axioms and specific knowledge far domain. The bottom level, the axiom, specifies the semantics of concepts and relations of knowledge so that ambiguity of the semantics can be alleviated. The middle level is a product development knowledge map; it defines the concepts and the relations of the product domain common knowledge and guides engineers to process their engineering decisions. The middle level is then classified further into more detailed levels, such as generic product level, specific product level, product version level, and product item level for PLM. The top level is specialized knowledge fer a specific domain that gives the solution of a specific task or problem. It is classified into three knowledge types: expert knowledge, engineering function knowledge, and data-analysis-based knowledge. This proposed framework is based on ontology to accommodate a comprehensive range of unambiguous knowledge for PLM and is represented with first-order logic to maintain a uniform representation.

Purpose: This study aimed to analyze the impact of rapid cycle deliberate practice (RCDP) simulation education on advanced cardiac life support knowledge, confidence, satisfaction, and performance ability among paramedic students, and provide basic data on the appropriate methods of educational instruction. Methods: The 48 subjects to be instructed were divided into the traditional simulation education group and the RCDP simulation education group. Six participants were randomly assigned to each group and pre-surveyed. They were then exposed to a lecture about advanced cardiac life support related theories for 60 min and post-surveyed through questionnaires with the same learning goals and scenarios. Results: The advanced cardiac life support knowledge (t=-4.813, p=.000) and performance ability (t=-2.903, p=.006) were significantly different between the traditional simulation education and RCDP simulation education groups The results also showed a significant difference in attach monitor (z=6.857, p=.009), analyze EKG rhythm (z=11.111, p=.001), and defibrillation (z=12.632, p=.000), indicating differences in performance capabilities between the two groups. Conclusion: To improve advanced cardiac life support knowledge, performance ability, and confidence in the paramedic students who receive RCDP simulation education, simulation education methods that are appropriate for the subjects being taught, and detailed learning goals and feedback are necessary.

Mixture electrodes of a graphite having a good cycle performance and a silicon monoxide (SiO) having a high capacity are fabricated and their cycle performances are evaluated as negative electrodes for lithium-ion batteries. The electrode prepared by mixing the natural graphite and carbon-coated SiO in a mass ratio of 9:1 shows a reversible capacity of $480mAh\;g^{-1}$, 33% higher than that of graphite. However, the capacity deteriorates continuously upon cycling due to the volume change of silicon monoxide. In this study, the factors that can improve the cycle performance have been discussed through the change in the configurations of the electrode and the electrolyte. The electrode using the carboxymethyl cellulose (CMC) binder shows the best cycle performance compared to the conventional binders. The electrode sing the CMC and styrene-butadiene rubber (SBR) binder not only has almost the similar cycle characteristics with the electrode using the CMC binder but also has the better rate capability. When the fluoroethylene carbonate (FEC) is used as an electrolyte additive, the cycle life is improved. However, the electrolyte with 5 wt% of FEC is appropriate because the rate capability decreases when the content of FEC is increased to 10 wt%. In addition, when the mass loading of the electrode is lowered, the cycle performance is greatly improved. Also, enhanced cycle performance is achieved using the roughened Cu current collector polished by abrasive paper.

In this study, we propose an ontology based knowledge service system for efficient and sustainable sports events management with information and communication technology. For delivering personalized information and knowledge which relate on sports event operation and management, we analyze the core operations and suggest structure of sport event life-cycle process. Also, we design ontology based knowledge service as proposed in this study to apply on a golf tournament event management system.
