1991년 이후 예능프로그램은 게임화 특성이 강해지는 방향으로 진화하고 있다. 1991년~1998년과 2008년~2014년을 비교하여 지상파방송사의 주말예능프로그램 255개를 분석한 결과, 예능프로그램은 버라이어티 포맷에서 리얼리티 포맷으로, 승패와 미션수행을 경쟁의 요인으로 집중 부각하는 방향으로, 잘 짜맞추는 플롯에서 엉키게 하는 플롯으로 진화하고 있다. 단순하게 포맷 자체의 변화만을 의미하는 것은 아니다. 리얼리티 포맷 내에서도 경쟁 요인과 플롯 구성 방식에 따라 다양한 변화가 지속적으로 이루어지고 있다는 함의를 내포한다. 향후에도 게임화, 플롯, 경쟁 방식 간의 상호작용은 방송콘텐츠 포맷을 더욱 창의적으로 변화시키는 핵심요인이 될 것으로 판단된다.

This paper aims to propose the educational concept and design model of a Smart Board Game appropriate for lower elementary grade students. The Smart Board Game refers to a hybrid, or 'convergent', game format based on the offline format of the conventional board game augmented through the use of smart devices. The substantive aspects of this game format utilize the procedural deduction and problem-solving skills applicable in storytelling methodologies and games, in order to generate and propose contents ideal for the educational environment. The development of the Smart Board Game is conducted through the following stages. First, the study analyzes a number of Smart Board Games currently popular in Korea and abroad, based on identification of the key components and processes of the board game format. The subsequent review of the science curriculum for lower elementary grades aims to determine the aspects conducive for application to Smart Board Games. Lastly, the theoretical framework outlined through the previous stages is used as the basis for the proposal of a detailed model of contents for the smart board game concept.

선박에서 발생되는 다양한 형태의 디지털 정보를 그 특성에 따라 적절하게 처리하기 위해서는 용도에 적합한 네트워크의 구성이 필요하다. 이러한 필요성에 부합하는 표준으로 NMEA 2000과 IEC 61162-4가 있다. NMEA 2000은 실시간 데이터의 처리에 적합한 표준이고, IEC 61162-4는 데이터의 통합 관리에 적합한 표준이다. 따라서, NMEA 2000 데이터를 통합하여 관리하기 위해서는 IEC 61162-4 포맷으로 변환하여야 한다. 본 논문에서는 이러한 변환을 위한 참조화일 및 알고리즘을 제시하고 그 구현 결과를 기술한다.

The purpose of this study is to first evaluate the seismic behavior of ageing arch bridges by using the Intensity Measure - based demand and DCFD format, which is referred to as the fragility-hazard format. Then, an investigation is performed for their seismic vulnerability. Analytical models are created for bridges concerning different features and these models are subjected to Incremental Dynamic Analysis (IDA) analysis using a set of 22 earthquake records. The hazard curve and results of IDA analysis are employed to evaluate the return period of exceeding the limit states in the IM-based probabilistic performance-based context. Subsequently, the fragility-hazard format is used to assess factored demand, factored capacity, and the ratio of the factored demand to the factored capacity of the models with respect to different performance objectives. Finally, the vulnerability curves are obtained for the investigated bridges in terms of the loss ratio. The results revealed that decreasing the span length of the unreinforced arch bridges leads to the increase in the return period of exceeding various limit states and factored capacity and decrease in the displacement demand, the probability of failure, the factored demand, as well as the factored demand to factored capacity ratios, loss ratio, and seismic vulnerability. Finally, it is derived that the probability of the need for rehabilitation increases by an increase in the span length of the models.

공공도서관 문화프로그램에 대한 중요성이 커짐에 따라 그 경제적 효과에 대하여 전반적으로 평가할 필요성이 제기되어 왔다. 본 연구는 문화프로그램의 경제적 가치를 분석하기 위한 방법으로 기존에 사용되어 온 가상가치평가법의 대안으로 DM 포맷과 IBM 포맷을 제안하였다. 또한 이 모형을 공공도서관 이 적용할 수 있도록 사례분석을 통해 그 과정을 구체적으로 설명하고 있다. 이 연구는 가상가치평가법의 바이어스를 최대한 감소함으로써 공공도서관의 정확한 가치를 평가할 수 있는 기본 틀을 마련하였다는 데에 그 의의가 있다.

Recently, the structured data format in RDF/OWL has played an increasingly vital role in the semantic web. We converted pediatric and oncologic nuclear medicine imaging reports in free text into RDF/OWL format and evaluated the usefulness of nuclear medicine imaging reports in RDF/OWL by comparing SPARQL query results with the manually retrieved results by physicians from the reports in free text. SPARQL query showed 95% recall for simple queries and 91% recall for dedicated queries. In total, SPARQL query retrieved 93% (51 lesions of 55) recall and 100% precision for 20 clinical query items. All query results missed by SPARQL query were of some inference. Nuclear medicine imaging reports in the format of RDF/OWL were very useful for retrieving simple and dedicated query results using SPARQL query. Further study using more number of cases and knowledge for inference is warranted.

MS Office suit software is the most widely used electronic documents by a large number of users in the world, which has absolute predominance in office software market. MS Office 2007-2013 documents, which use new office open extensible markup language (OOXML) format, could be illegally used as cover mediums to transmit secret information by offenders, because they do not easily arouse others suspicion. This paper proposes nine forensic methods and an integrated forensic tool for OOXML format documents on the basis of researching the potential information hiding methods. The proposed forensic methods and tool cover three categories; document structure, document content, and document format. The aim is to prevent covert communication and provide security detection technology for electronic documents downloaded by users. The proposed methods can prevent the damage of secret information embedded by offenders. Extensive experiments based on real data set demonstrate the effectiveness of the proposed methods.

Based on the growing demand for neural network technologies, various neural network inference engines are being developed. However, each inference engine has its own neural network storage format. There is a growing demand for standardization to solve this problem. This study presents interworking techniques for ensuring the compatibility of neural networks and data among the various deep learning frameworks. The proposed technique standardizes the graphic expression grammar and learning data storage format using the Neural Network Exchange Format (NNEF) of Khronos. The proposed converter includes a lexical, syntax, and parser. This NNEF parser converts neural network information into a parsing tree and quantizes data. To validate the proposed system, we verified that MNIST is immediately executed by importing AlexNet's neural network and learned data. Therefore, this study contributes an efficient design technique for a converter that can execute a neural network and learned data in various frameworks regardless of the storage format of each framework.

Background: The current status of ACE format MCNP/MCNPX libraries by NDC of KAERI is presented with a short description of each library. Materials and Methods: Validation calculations with recent nuclear data evaluations ENDF/BV-II. 0, ENDF/B-VII.1, JEFF-3.2, and JENDL-4.0 have been carried out by the MCNP5 code for 119 criticality benchmark problems taken from the expanded criticality validation suite supplied by LANL. The overall performances of the ACE format KN-libraries have been analyzed in comparison with the results calculated with the ENDF/B-VII.0-based ENDF70 library of LANL. Results and Discussion: It was confirmed that the ENDF/B-VII.1-based KNE71 library showed better performances than the others by comparing the RMS errors and ${chi}^2$ values for five benchmark categories as well as whole benchmark problems. ENDF/B-VII.1 and JEFF-3.2 have a tendency to yield more reliable MCNP calculation results within certain confidence intervals regarding the total uncertainties for the $k_{eff}$ values. Conclusion: It is found that the adoption of the latest evaluated nuclear data might ensure better outcomes in various research and development areas.
