The National Science and Technology Knowledge Information Service (NTIS) provides information on national R&D projects. Project information consists of meta-information such as 'project name', 'project performance institution', 'research manager name', and text explaining projects such as 'research goal', 'research content', and 'expected effect'. There is a problem that it takes a lot of time to find the desired project information by checking all of the "research goals" or "research contents" in the list of results of searching for 1 million project information. To solve this problem, this paper proposes a project information summary system that summarizes the parts consisting of long texts within the national R&D project information. By analyzing the linguistic characteristics of the Korean language, a preprocessor was built and a project information summary model based on natural language processing technology was developed to process preprocessed text information. Through this, project information composed of long sentences is provided in a compressed and summarized form, which will help users to easily and quickly infer the overall content with the summary information alone.

본 논문은 영어-한국어 교차언어 정보검색의 질의어 번역에 대한 중요한 자원으로 활용되는 병렬 말뭉치의 품질 향상을 위해서, 위키피디아의 비교 말뭉치로부터 자동으로 병렬 문장을 추출하여 활용하는 기법을 제안한다. 기존 연구에서 질의어 번역을 위해 위키피디아의 이중 어휘 사전 및 동의어, 다의어 정보를 구축하고, 기 기축된 병렬 말뭉치와 함께 활용하여 여러 의미를 가진 번역 후보 단어들 중, 최적의 단어를 선택하는 방법을 이용하고 있다. 여기서 활용되는 병렬 말뭉치는 질의어 번역에서 가장 중요한 자원이다. 하지만, 기 구축된 병렬 말뭉치는 양이 적거나, 특정 영역을 중심으로 구성되어 있는 문제가 있다. 이러한 문제를 해결하기 위해, 본 논문은 위키피디아로부터 자동 병렬 문장 추출 기법을 이용, 대량의 영어-한국어 간 병렬 말뭉치를 구축하고, 이를 교차언어 정보검색을 위한 질의어 번역에 적용하여 개선을 보인다. 실험의 성능 비교를 위해서 NTCIR-5 데이터를 이용하였으며 기 구축된 세종 병렬 말뭉치를 활용한 질의어 번역의 성능이 MAP 31.5%, R-P 33.0%에서, 새롭게 구축한 위키피디아 병렬 말뭉치를 활용한 질의어 번역의 성능이 MAP 34.6%, R-P 34.6%로, 각각 MAP 3.1%와 R-P 1.6%의 성능 향상을 보였다.

This study was conducted to explore the effects of semi-structured $DIRFloortime^{(R)}$ treatment on the enhancement of language comprehension and information processing of children with high-performance autistic spectrum disabilities. We measured the general characteristics of the test subjects, which are level of autism, total intelligence, language comprehension and information processing indicators. The intervention method used was a semi-structured $DIRFloortime^{(R)}$ therapy using board game intervention program after revising and supplementing the expert content validity. A pre/post-test for a group was designed as a similar experiment and the pre/post test was initiated with the t certification at .05 of significance level. After initiating the program, the post test has shown that the language comprehension indicators showed statistically significant levels of difference (p<.001) and the information processing indicator also had a statistically significant effect (p<.001). There was a statistically significant difference (p<.001) in the level of verbal comprehension index after the program implementation, and statistically significant differences in the information processing index (p<.001). The semi-structured $DIRFloortime^{(R)}$ treatment using boardgames for enhancing the language comprehension and information processing indicators of children with high performance autistic spectrum disorder had a significant effect.

In planning and evaluating government R&D programs, one of the first steps is to understand the government's current R&D investment portfolio - which fields or topics the government is now investing in in R&D. Analysis methods of an investment portfolio of government R&D tend traditionally to rely on keyword searches or ad-hoc two-dimensional classifications. The main drawback of these approaches is their limited ability to account for the characteristics of the whole government investment in R&D and the role of individual R&D program in it, which tends to depend on the relationship with other programs. This paper suggests a new method for mapping and analyzing government investment in R&D using a combination of methods from natural language processing (NLP) and network analysis. The NLP enables us to build a network of government R&D programs whose links are defined as similarity in R&D topics. Then methods from network analysis show the characteristics of government investment in R&D, including major investment fields, unexplored topics, and key R&D programs which play a role like a hub or a bridge in the network of R&D programs, which are difficult to be identified by conventional methods. These insights can be utilized in planning a new R&D program, in reviewing its proposal, or in evaluating the performance of R&D programs. The utilized (filtered) Korean text corpus consists of hundreds of R&D program descriptions in the budget requests for fiscal year 2017 submitted by government departments to the Korean Ministry of Strategy and Finance.

이 논문은 부산대학교 전자계산학과 인공지능 연구실에서 개발한 정보검색 시스템 "미리내"의 적합성 피드백 방법을 분석하고, 그 방법들의 검색 효율을 비교 분석하였다. "미리내"에서 질의문은 자연언어 질의문을 사용하고 재검색을 위한 적합성 피드백은 원질의문에서 검색된 문서 중 이용자가 직접 선택한 적합 문서에서 추출한다. 적합성 피드백은 크게 단어 확장(Term Expansion)을 위한 단어 선택 방법과 추가될 단어에 가중치를 부여하는 단어 가중치 부여(Term Weighting)의 2가지 요소로 이루어진다. 단어 선택을 위해서는 적합 문서에 나타난 단어 빈도합(tf), 역문헌빈도(idf), 적합 문서 중에서 해당 단어가 있는 적합 문서의 비율(r/R) 등의 정보를 이용한다. 단어 가중치 부여 방법으로는 정규화 또는 코사인 함수를 이용하여 부여하였다. 단어확장에는 tfidf가 tfidf(r/R)보다 정확도 면에서 나은 향상율을 보였으나, 30위 내 검색된 적합문서의 수를 비교해 보았을 때 tfidf(r/R)의 정확도가 높았다. 단어 선택 방법에서 계산된 값을 정규화하여 가중치를 부여하였을 때 보다 코사인 함수를 이용하여 가중치를 부여하였을 때 정확도가 높았다. 실험은 KT-Set 2.0 (4391 건), 동아일보 96 년 신문기사(70459 건)를 대상으로 수행하였다.

Solar energy is one of the most important alternative energy sources which have been shown to meet high levels of heating and cooling demands in buildings. However, the efficiencies to satisfy these demands using solar energy significantly vary based on the characteristics of individual building. Therefore, this paper is focused on developing the methodology which can help to design optimal solar system for heating and cooling to be in cooperated within the existing buildings according to their load profiles. This research has established the Solar Heating and Cooling (SHC) system which is composed of collectors, absorption chiller, boiler and heat storage tank. Each component of SHC system is analyzed and made by means of Modelica Language and Pistache tool is verified the results. Sequential approximate optimization (SAO) and meta-models determined to 15 design parameters to optimize SHC system. Finally, total coefficient of performance (COP) of the entire SHC system is improved approximately 7.3% points compared to total COP of the base model of the SHC system.

This paper presents the java bytecode-to-.NET MSIL intermediate language translator which enables the execution of the java program in .NET environments without JVM(java Virtual Machine), translating bytecodes produced by compiling java programs into MSIL codes. Java, one of the most widely used programming languages recently, is the language invented by James Gosling at Sun Microsystems, which is the next generation language independent of operating systems and hardware platforms. Java source code is compiled into bytecode as intermediate code independent of each platform by compiler, and also executed by JVM. .NET language such as C# and .NET platform in Microsoft Corp. has been developed to meet the needs of programmers, and cope with Java and JVM platform of Sun Microsystems. After compiling, a program written in .NET language is converted to MSIL code, and also executed by .NET platform but not in JVM platform. For this reason, we designed and implemented the java bytecode-to-.NET MSIL translator system for programs written in java language to be executed in the. NET platform without JVM. This work improves the execution speed of programs, enhances the productivity, and provides a environment for programmers to develop application programs without limitations of programming languages.

According to studies of many language education researchers including R. Ellis, a representative English education specialist, it is an effective and important method to improve the authenticity of English by learning a foreign language repeatedly in learner's actual situation. In this paper, we propose a foreign language learning service combined with context-awareness service, and develop foreign language learning contents which improves the authenticity of English learning based on the service. This approach is based on a study on digital education contents that helps learners to acquire a foreign language in an unconscious state in their real environment and a study to analyze the empirical characteristics of users based on real-time multi-sensed data.

Truncated forms (truncata) in English hypocoristic words have been argued to be faithful to their bases. This means that “ ... the base of truncation is an output form"”(Benua 1995:6,12). For example, in some non-rhotic dialects where syllable-final [r]s are deleted, the [r]s of truncated names such as Gar [gær] (truncated form of Garry [gæri]) are not deleted although they are syllable-final. This is an example of base-truncatum identity. That is, the syllable-final [r] is retained to make the truncatum more faithful to its base. However, there are many English hypocoristic names which are not faithful to their base forms. For example, Letty [equation omitted] (hypocoristic form of Latitia [equation omitted]) is not faithful to its base; the first vowel and the second consonant of the truncatum are not identical to the corresponding segments of the base. It will be argued, therefore, that some truncated forms are more faithful to the inputs than the bases. It will also be argued that McCarthy and Prince's (1995) Full Model is needed to deal successfully with all the phenomena related to truncation.

Social scientists in North America, especially anthropologists, folklorists and linguists, who focus on the study language use and its connection to society, use a variety of labels to describe what they do. Among the best known are 'anthropological linguistics' , 'linguistic anthropology', and 'sociolinguistics'. All of these labels imply that their focus is on the study of language usage in society and culture for their teaching, research and publications. In this paper I am examining the intellectual issues and history that underlie the differences in the labels. The differences and similarities that characterize them are discussed. The author proposes 'linguistic anthropology' as the most useful disciplinary terminology if the study of language combined with culture is to be 'community-centric' and not only 'profession-centric' . He encourages a renewed focus on working with communities. Also, a need to find ways to engage Indigenous members of minority language communities more actively should be a primary goal in the process of 'academic' language work. This is important due to the loss rapid extinction of the many of the world's languages. The author points out that it does matter what we call the work we do, as a label may carry a message of meaning, intent and focus.
