용어추출은 도메인 텍스트 모음으로부터 도메인 용어 목록을 인식하는 작업이다. 용어추출의 기존 효과적인 방법들은 비교사 방식으로 동작하며, 후보 용어 집합을 추출하는 작업과 후보 용어에 용어중요도를 할당하는 작업을 주요 단계로 포함한다. 후보 용어의 용어중요도 계산과 관련하여 본 논문에서는 후보 용어의 내부 및 외부용어집합을 활용한다. 내부용어집합은 후보 용어에 포함된 다른 짧은 용어들의 집합이며, 외부용어집합은 후보 용어가 포함된 다른 긴 용어들의 집합이다. 본 논문에서는 후보 용어의 내부 혹은 외부용어집합으로부터 후보 용어의 용어 강도를 계산하는 다양한 강도 함수들을 제시하고, 이들 용어 강도 값들과 C-value 점수를 결합하는 용어중요도 계산 방법을 소개한다. 생물학 및 전산언어학 분야 영어 데이터셋을 사용한 성능 평가에서는 제안된 방법의 용어추출 성능을 비교하고 분석한다. 제안된 방법은 생물학 및 전산언어학 분야 데이터셋에 대해 각각 최대 1%와 3% 차이의 성능 향상을 보였다.

본 연구에서는 마이크로 탄소 브러쉬 하전부와 평판형 금속 집진부로 구성된 저전력 소비형 2단형 전기집진기를 개발하였고, 특히 인체 위해성이 높은 $0.3{\mu}m$급의 미세한 오일 미스트에 대한 인가전압 및 소비전력별 집진효율 특성을 실험연구를 통해 고찰하였다. 하전부의 인가전압에 따른 단위 입자당 하전율과 입경별 집진효율을 측정함과 동시에 이론에 근거한 계산값과 비교해 보았으며, 9 주 동안의 장시간 운전을 통해 지속적으로 포집된 오일 미스트에 의한 전기집진기의 성능을 열유체역학적인 관점에서 변화를 조사하였다.

An electrostatic precipitator (ESP) has a low pressure drop and a high collection efficiency but its collection efficiency can be reduced due to dust accumulation on the collection plates during long-term operations. In order to maintain the initial dust collection efficiency, it is necessary to periodically clean the collection plates. The common cleaning methods are using physical impacts or water sprays. These cleaning methods can lead to damage to the collection plate or generate wastewater. Herein, we implemented an electrodynamic screen (EDS) for ESP cleaning and evaluated its surface cleaning performance of particles. The EDS is an electrostatic system that can electrostatically repel particles on surfaces, allowing it to clean the ESP without causing damage and wastewater generation. Our evaluation included the analysis of the effects of AC voltage characteristics, electrode configuration and environmental conditions on the cleaning performance of the EDS with the aim of achieving effective surface cleaning. It has been demonstrated that activating the EDS cleans up to 65% of the particles on the surface, which indicates about 94% of our target cleaning zone.

Beauty Art is an act which makes a face beautiful using various methods such as permanent, manicure and make-up. Recently, Beauty Art is recognized as the personal culture expressing the value of beauty and spirit. Therefore, there are growing interests in the comprehensive study of Beauty Art nor only from the beauty industries but also from academia, because Beauty Art is the high value-added field and Is recognized as a style of the dress. The purpose of this study is to open a new view to understand the Nail Art as a fold of experimental plastic art. The arctic expression is added to Beauty Art to develop it from the routine technique of the make-up and hairstyling to creative art. Assemblage is adopted to provide Beauty Art with fine harmonious expression which develop Nail Art into interesting and unique art area. Assemblage meaning compounding or collection is a technique through which three-dimension is added to two-dimension paintings, and which is an expression of an art work by recollection of miscellaneous articles or waste materials. Assemblage is a term which Jean Dubuffet coioned first in order to differentiate collage used by Picaso or Braque. Here, I present Nail Art Designs which applied Jean Dubuffet's works focusing on Automaticity and Happenstantial phenomena of materials, Materialization, and Directness. These features are characteristics of Assemblage which basic frameworks are fantastic collection, accumulation, constructive collection, and object collection.

The Long-Term Development Plan of the Pusan National University(PNU) has announced on 1991 in order to reach its roles and levels as an University with international standards, a Graduate School research-oriented and a core university in its community through accomplishment of this Plan. University libraries would be planned to support their universities' goals. Therefore the Library of PNU is facing on the task for supporting the Plan. The Collection for Korean Classical Materials (CKCM) is not limited in Korean Literature, Korean History, Korean Philosophy fields but covered the academic fields except a hightech science : Humanities, social science. pure science, applied science and arts etc. However, the Library of PNU does not have the organization, special librarian and budget for CKCM. Under this notion organization, budget and librarian for the collection would be followed. The CKCM contains the original editions, photography editions, copied issues. microform reproductions with comprehensive subjects in the fields of studies. Especially for the collection of treasure books the role of the Library of PNU induce to open individuals' collections or families' collections to public through the Library. The equipments for preserving rare books and treasure books are the conditioners for humidity and temperature, automatic extinguishment system. The reference materials, copy machine and reading room are requested for the user service of CKCM. The materials would be one of the most important thing in study and research. Therefore the Library of PNU need to pay attention to develop and preserve CKCM.

The basis of cyber trading has been sufficiently developed with innovative advancement of Internet Technology and the tendency of stock market investment has changed from long-term investment, which estimates the value of enterprises, to short-term investment, which focuses on getting short-term stock trading margin. Hence, this research shows a Short-term Stock Price Forecasting System on Learning Agent System using DTA(Decision Tree Algorithm) ; it collects real-time information of interest and favorite issues using Agent Technology through the Internet, and forms a decision tree, and creates a Rule-Base Database. Through this procedure the Short-term Stock Price Forecasting System provides customers with the prediction of the fluctuation of stock prices for each issue in near future and a point of sales and purchases. A Human being has the limitation of analytic ability and so through taking a look into and analyzing the fluctuation of stock prices, the Agent enables man to trace out the external factors of fluctuation of stock market on real-time. Therefore, we can check out the ups and downs of several issues at the same time and figure out the relationship and interrelation among many issues using the Agent. The SPFA (Stock Price Forecasting System) has such basic four phases as Data Collection, Data Processing, Learning, and Forecasting and Feedback.

Purpose - This research investigates whether e-service quality has the influence on long-term orientation, consumer commitment, and satisfaction. Research design, data, and methodology - Data collection took place for 30 days from October 1, 2015 to October 31, 2015. 315 copies had been analyzed. Covariance structure analysis with credibility and factor analysis was conducted to verify this research hypotheses. Results - First, the lower dimension concepts of e-service quality, reliability, and tangibility had a significant influence on customer commitment, and responsiveness had a significant negative influence. However, aesthetics did not have a significant influence on that. Secondly, aesthetics had a significant influence on long-term orientation, but reliability, tangibility, and responsiveness did not have a significant influence. Thirdly, reliability, tangibility, and aesthetics had a positive influence on customer satisfaction. However, responsiveness had a negative influence. Fourthly, customer commitment had a significant and positive influence on customer satisfaction, but customer commitment and customer satisfaction had a negative influence on long-term orientation. Conclusions - This research verifies the influencing relationship between e-service quality of a franchise coffee shop application with customer commitment, customer satisfaction, and long term orientation. By the results of this research, possibility of application and expansion of theory has been proven.
