1970년대 중반 일본에서 만들어진 메카트로닉스(Mechatronics)라는 용어는 기계공학(Mechanics)과 전자공학(Electronics)의 합성어로 1980년대 이후 전세계적으로 널리 사용되었다. 이후 컴퓨터 기술의 급속한 발전에 힘입어 메카트로닉스는 로봇, 공장자동화, CNC공작기계 등 현대산업의 근간을 이루는 핵심 기술로 자리매김 하였다. 최근에는 학문의 경계를 허무는 작업들이 더욱 속도를 내고 있는 가운데, 생활에서 늘 접하는 휴대폰, TV, 빔프로젝트 등의 제품에 시각적 신호를 창출하기 위한 광학적 요소가 결합되고 있다. 이를 우리는 옵토메카트로닉스(Optomechatronics)라는 영역으로 분류한다. 여기에 생체공학(Bionics)과 나노기술(Nano technology)의 결합을 필요로 하는 제품들이 또한 바이오옵토메카트로닉스(Bio-Optomechatronics)또는 나노바이오 옵토메카트로닉스(Nano-Bioopmechatronics)등의 새로운 영역 창출을 준비하고 있다.

Architectural history traces the changes in architecture through various traditions, regions, overarching stylistic trends, and dates. This study identified terminologies related to the proximity and frequency in the architectural history areas by text mining and association analysis. This study explored terminologies by investigating articles published in the "Journal of Architectural History", a sole journal for the architectural history studies. First, key terminologies that appeared frequently were extracted from paper that had titles, keywords, and abstracts. Then, we analyzed some typical and specific key terminologies that appear frequently and partially depending on the research areas. Finally, association analysis was used to find the frequent patterns in the key terminologies. This research can be used as fundamental data for understanding issues and trends in areas on the architectural history.

This review was performed to outline the food ethics to the professionals in the field of food science and industries. Food ethics is the ethics or ethical consideration concerning food; while, the keywords of food ethics are a life, happiness and the wisdom. The ultimate goal as well as the first principle of food ethics is a sustainable living of human race. In order to reach the goal a coexistence of humans and nature, coexistence of humans and humans, and the fulfillment of essential requirements of a food are needed. The needs yield six categorical imperatives such as a respect for life, preservation of nature, distributive justice without deception or fakes, prior consideration of consumer, moderation and balance neither overs nor shorts, and the assurance of safety. The core principles corresponding to the categorical imperatives include a respect for life, environmental preservation, justice, priority of consumer, dynamic equilibrium, and the priority of safety. The core principles approach is a simple, clear, and practical method in solving ethical issues. The code of food ethics is also based on the core principles.

The main purpose of this paper is to investigate the effects of discourse topic and morpho-syntactic verbal information on the resolution of null pronouns in the Korean narrative text within the framework of the construction-integration theory (Kintsch, 1988, Singer & Kintsch, 2001, Graesser, Gernsbacher, & Goldman. 2003). For the purpose of this paper, two conditions were designed: an explicit condition with both a consistently maintained discourse topic and the person-specific verb modals on one hand, and a neutral condition with no discourse topic or morpho-syntactic information provided, on the other. We measured the reading tines far the target sentence containing a null pronoun and the question response times for finding an antecedent, and the accuracy rates for finding an antecedent. During the experiments each passage was presented at a tine on a computer-controlled display. Each new sentence was presented on the screen at the moment the participant pressed the button on the computer keyboard. Main findings indicate that processing is facilitated by macro-structure (topicality) in conjunction with micro-structure (morpho-syntax) in pronoun interpretation. It is speculated that global processing alone may not be able to determine which potential antecedent is to be focused unless aided by lexical information. It is argued that the results largely support the resonance-based model, but not the minimalist hypothesis.

The Science and Technology Information Service provided by the Korea Institute of Science and Technology Information (KISTI) is a service designed to allow users to easily and conveniently search and view content that is built similar to the general information service. NDSL is KISTI's core science, technology and information service, providing about 138 million content and having about 93 million page views in a year of 2019. In this paper, various insights were derived through the analysis of how science and technology information such as academic papers, reports and patents provided by NDSL is searched and utilized through web services (https://www.ndsl.kr) and search query words. In addition to general statistics such as the status of content construction, utilization status and utilization methods by type of content, monthly/weekly/time-of-day content usage, content view rate per one-time search by content type, the comparison of the use status of academic papers by year, the relationship between the utilization of domestic academic papers and the KCI index we analyzed the usability of each content type, such as academic papers and patents. We analyzed query words such as the language form of query words, the number of words of query words, and the relationship between query words and timeliness by content type. Based on the results of these analyses, we would like to propose ways to improve the service. We suggest that NDSL improvements include ways to dynamically reflect the results of content utilization behavior in the search results rankings, to extend query and to establish profile information through non-login user identification for targeted services.

Animation works have been peformed by the objective sensitivity and experience so far. Software designs have been also manufactured based on intelligent data because they are easy to objectify and digitalize. In contrast, there are many elements, which human senses are hard to objectify and digitalize. This study investigates how to digitalize and objectify human senses and how to use them as the quantitative data and its subject is a flying path. In the experiment, this study collects some sensitive words for how human beings express the living path. The evaluation words for sensitivity through the collected sensitive words are extracted and the sketch images for the flying path are collected from the extracted evaluation words for sensitivity. Based on the collected sketch images, the samples of real moving image, which are the core of this study, are manufactured. Then, quantification theory III and I are used in order to analyze the correlation between the sensitive words representing the flying path and the samples of moving image. As a result, this study can figure out the structure of sensitive words and the samples of moving image and analyze the physical stimulating elements for the flying path. The flying path corresponds to the path that the object has passed. Some unique sensitive words are expressed by means of interacting some sensitive stimulating elements after looking at such a path. There are some elements that stimulate the senses and they include the physical elements such as speed, rotation, pattern and length of arc. The purpose of this study is to objectify and quantify the animation works that are created by animators' subjective thought and experience and to use them in animation works in the future.

This paper presents the study on the rejection capability based on anti-phone modeling for vocabulary independent speech recognition system. The rejection system detects and rejects out-of-vocabulary words which were not included in candidate words which are defined while the speech recognizer is made. The rejection system can be classified into two categories by their implementation methods, keyword spotting method and utterance verification method. The keyword spotting method uses an extra filler model as a candidate word as well as keyword models. The utterance verification method uses the anti-models for each phoneme for the calculation of confidence score after it has constructed the anti-models for all phonemes. We implemented an utterance verification algorithm which can be used for vocabulary independent speech recognizer. We also compared three kinds of means for the calculation of confidence score, and found out that the geometric mean had shown the best result. For the normalization of confidence score, usually Sigmoid function is used. On using it, we compared the effect of the weight constant for Sigmoid function and determined the optimal value. And we compared the effects of the size of cohort set, the results showed that the larger set gave the better results. And finally we found out optimal confidence score threshold value. In case of using the threshold value, the overall recognition rate including rejection errors was about 76%. This results are going to be adapted for stock information system based on speech recognizer which is currently provided as an experimental service by Korea Telecom.

This study aims to conduct a comprehensive meta-study from the perspective of content analysis to explore trends in Korean academic research on the sharing economy by using the big data analytics. Comprehensive meta-analysis methodology can examine the entire set of research results historically and wholly to illuminate the tendency or properties of the overall research trend. Academic research related to the sharing economy first appeared in the year in which Professor Lawrence Lessig introduced the concept of the sharing economy to the world in 2008, but research began in earnest in 2013. In particular, between 2006 and 2008, research improved dramatically. In order to grasp the overall flow of domestic academic research of trends, 8 years of papers from 2013 to the present have been selected as target analysis papers, focusing on titles, keywords, and abstracts using database of electronic journals. Big data analysis was performed in the order of cleaning, analysis, and visualization of the collected data to derive research trends and insights by year and type of literature. We used Python3.7 and Textom analysis tools for data preprocessing, text mining, and metrics frequency analysis for key word extraction, and N-gram chart, centrality and social network analysis and CONCOR clustering visualization based on UCINET6/NetDraw, Textom program, the keywords clustered into 8 groups were used to derive the typologies of each research trend. The outcomes of this study will provide useful theoretical insights and guideline to future studies.
