본 논문에서는 생명체의 면역계에서 중요한 역할을 하는 세포독성 T세포의 생성과정의 하나인 긍정선택(positive selection)과 부정 선택(negative selection)을 모델링하여 침입에 의한 데이터 변경과 바이러스에 의한 데이터 감염 등을 탐지할 때 가장 중요한 요소인 변경 검사 알고리즘을 개발하였다. 제안한 알고리즘은 면역세포의 생성시 MHC 인식부를 형성해 주는 긍정 선택을 자기 인식 알고리즘으로 구현하여 컴퓨터에서 자기로 인식해야하는 파일이나 기능에 대해 MHC 인식부를 형성하고, 또한 항원 인식부를 형성하는 부정 선택을 이용해 변형 검지기(anomaly detector)를 구성한다. 따라서 제안한 알고리즘은 실제 면역세포와 마찬가지로 자신과 침입자 모두에 대한 인식기를 가지고 변경을 탐지하게 된다. 시뮬레이션을 통하여 자기파일의 일부가 변경되었을 때와 블록이 변경되었을 때에 대하여 두 가지 방법을 이용한 변경 검사 알고리즘의 특성과 유효성을 밝힌다.

본 연구는 대화 시스템에서 처리되는 사용자 발화의 의도 분석 기법과 담화 정보를 사용하여 음성 인식 결과로서의 인식 후보 문장들을 재순위하는 방법을 제안한다. 담화 정보는 사용자 발화의 의도 분석에 매우 중요한 자질로 사용되고 있기 때문에 음성 인식 결과들의 후보를 선택하는 문제에서도 담화 정보는 매우 중요한 자질로 사용될 수 있다. 음성 인식 결과의 후보 문장들을 모두 의도 분석 과정을 거치고 각각의 후보 의도들과 이전 담화 정보의 연관성을 이용하여 음성 인식 결과를 재순위화 한다. 실험을 통하여 재순위 과정을 수행한 결과 1순위 음성 인식 결과는 재순위 과정을 거치지 않는 결과에 비해 7.08%의 오류 감소율을 보였다.

An advance in digital technologies and an introduction of HDTV contents production systems have made innovative changes in a TV broadcasting program and video production environment. The role of HD contents production experts is particularly getting more important to have a competitiveness in digital video production. It is necessary to develop a professional training and reeducation program that is based upon the perception of production experts. In this paper, we ed the perception of video production professionals and analyzed their requirements. With a DACUM job analysis method, 9 job duties and 71 tasks were retrieved to establish a research model. Then the performing frequency, importance, and difficulty in video editor's duties were analyzed and discussed.

In this paper, impact of science and technology information service quality satisfaction and perceived importance on the user loyalty was studied to find the way of improvement of information service quality. To analyze the impact among service quality variables, the research questions and hypothesis are set and statistical analysis on 641 survey answers was conducted. The correlation between satisfaction and perceived importance regarding each service quality item was high. Relationship between satisfaction of every item of the service quality and overall satisfaction was verified by multiple regression analysis. As a result, the five out of seven independent variables are statistically significant influence to the dependent variable. Relationship between the perceived importance and loyalty for each item was verified by multiple regression analysis was confirmed that the four out of seven independent variables are statistically significant influence to the dependent variable. The overall satisfaction is having an effect on loyalty verified through simple regression analysis.

This study examines international tourists 'perceived images and service quality of Korean foods. A survey was conducted to international tourists(Chinese, Japanese, American) visiting Korea. The results of study show that there is a significant difference in several attributes of Korean traditional foods as perceived by international tourists along their nationality. Particularly, American tourists tend to highly evaluate Korean foods as ones good for health. The perceived attractiveness of Korean foods in terms of color and shape is higher for Chinese and Americans than Japanese. A distinct difference is also found in the importance and performance attributes of perceived quality of Korean foods by the nationality of tourists. The results of IPA for the perceived quality of Korean traditional foods show that the restaurant facility and atmosphere are identified as the ones that need to be improved across all the tourists.

The purpose of this paper is illuminating positively the perception and compliance rate of local food principles in Korea. The results are as follows. First, in terms of the perception rate, social trust and local production/consumption are the most important components rather than eco-friendliness. This means the importance of both spatial and social aspects of local food concept. Second, in terms of the compliance rate, social trust and shortened food chain are well complied, rather than eco-friendliness and shortened food miles. Third, in terms of the difference between perception and compliance rate, the social aspects such as eco-friendliness, social trust, and shortened food chain has shown relatively smaller difference than the spatial aspects such as shortened food miles and local production/consumption.

The purpose of this study is to analyze the importance and performance of CK-1, The research subjects were self-enrolled questionnaires for students who took social economics subjects and analyzed the importance and performance using IPA. As a result of the research, it is necessary to establish the basis of social economic specialization in order to achieve the goal of CK-1, and it is necessary to establish educational curriculum related to industry and academy in addition to cultivating creative talents. And to improve the importance of these programs and improve their performance in order to enhance the undergraduate education and attract the creative economy. The implications of this study are as follows: The results of the evaluation to achieve the goals of CK-1 recognize that the importance and the performance of the social economy students are high. However, It is necessary to make efforts to improve the university constitution, to improve the education of the undergraduate education, and to attract the creative economy in order to characterize the local university targeted by the Ministry of Education and the project team.

The development of speech recognition processing technology has been applied and used in various video and streaming services along with STT and TTS technologies. However, there are high barriers to clear written expression due to the use of dialects and overlapping of stop words, exclamations, and similar words for voice recognition of actual conversation content. In this study, for ambiguous dialects in speech recognition, we propose a speech recognition technology that applies dialect key word dictionary processing method by category and dialect prosody as speech recognition network model properties.

This study was conducted to provide basic data for improving nursing management practice by comparing and analyzing the perceptions of nursing students and clinical instructors about the importance of the learning contents of nursing management and their practical experience. The final 343 copies were analyzed using the Mann-Whitney test and cross-analysis, targeting 4th-grade students and clinical instructors at three universities. Both nursing students and clinical instructors recognized 'communication', 'interpersonal relationship', 'responsibility', 'trust', and 'morality' as important factors in the evaluation items of practice. Among the top 10 most importantly recognized items among nursing-management practice learning content, six items ('infection control', 'nursing record management', 'patient nursing management', 'drug management', 'patient safety', and 'nursing malpractice') were matched in the two groups. Moreover, clinical instructors recognized that interpersonal relationships and relationship ethics were important, while nursing students chose legal responsibility. As a result of the practical experience analysis between the two groups, nursing students had high experience of indirect participation, but the clinical instructors had a high experience of direct instruction. A plan is needed to reduce the difference by establishing an organic partnership relationship between the university and practice institutions and increase the experience of direct practice of nursing students.

현재 철도는 물류의 운송과 대중교통수단으로 다양하게 활용되고 있다. 또한 친환경적인 면에서 매우 중요한 교통수단으로 각광을 받고 있다. 이에 따라 철도의 안전은 고려해야 할 가장 중요한 부분 중에 하나이다. 특히 철도의 건널목과 역사 내의 플랫폼과 같은 개방된 공간에 대한 안전관리는 매우 중요하다. 개방된 공간에서는 사고발생의 위험요소들이 다수 존재하기 때문에 이러한 위험요소들을 줄이기 위해 열차의 1차적인 통제를 담당하는 기관사와의 상황인식 정보의 공유가 필요하다. 상황인식 정보는 특정 공간에 따라 다양하게 존재할 수 있다. 따라서 OSGi 플랫폼을 사용하여 다양한 상황인식 정보들을 공유하고 활용할 수 있도록 하는 것이 본 연구의 목적이다.
