바이오 문헌으로부터의 의미 있는 객체 추출 및 상호작용 관계 추출은 수 많은 바이오 문헌으로부터 유용한 정보를 얻기 위한 필수적인 과정이다. 특히 문헌으로부터 유전자 또는 단백질 이름과 같은 바이오 객체를 정확하게 인지하는 것은 새로운 객체인식의 어려움과 객체를 찾기 위한 특징 패턴의 다양성으로 인해 도전적인 과제로 남아있다. 본 논문에서는 전처리 과정을 거친 문헌 데이터로부터 12개의 의미 있는 속성들을 선택하였다. 선택된 속성에 데이터마이닝 기법중 하나인 속성 추출 기법을 적용하여 객체를 분류하는데 있어 의미 있는 속성들을 추출하였다. 특징 추출 방법과 분류 알고리즘이 분류 성능에 미치는 영향을 평가하기 위해 각 방법의 정확도를 사용하여 분류 성능을 비교였으며, Gain Ratio Attribute Evaluation과 Symmetrical Uncertainty Attribute Evaluation 기법에 의해 추출된 속성이 가장 정확한 분류 성능을 보여주었다.

The purpose of this research is to examine the effect of the recognition on hotel customer's economic environment on attributes of hotel selection and customer loyalty. This research could suggest that the results of this research will help to establish positive strategies in all the processes of decision-making by customers who directly influence the behaviors of hotel customers as data of management of hotel companies. Firstly, detailed verification findings of regression analysis the recognition on economic environment and attributes of hotel selection were suggested as following; Recognition on economic environment influenced on guest room service, front service, food and beverage service, general environment, subsidiary facilities. Secondly, in case of the recognition on economic environment and customer loyalty, outer economy environment and information environment effected on customer loyalty.

SNS has been advanced from first to third generation by changing its service format in various ways. Nowadays, image-based SNS such as instagram and pinterest where users communicate via images has become popular as third generation service. Due to the fact that users communicate especially through images, image-based SNS utilizes images in different ways compared to other SNS. This study derived various characteristics of images in image-based SNS, and observed how users perceive each of them differently. Also, relationship between the characteristics and user satisfaction on image-based SNS is analyzed. The characteristics include 6 items; 'implicity', 'recordability', 'expressing identity', 'indirect experience', 'temporary amusement', and 'stimulating desire.' As a result of comparing user perception regarding those 6 characteristics, recordability and indirect experience were highly recognized than other characteristics. Also, according to users' age, motivation of using image-based SNS, and number of followers they have, users perceived each characteristic in different level. Finally, relationship between the characteristics and user satisfaction was analyzed, and the result showed that indirect experience had positive influence to user satisfaction. Regarding indirect experience, it was highly perceived by users and also had positive influence to their satisfaction, which means it is the most typical characteristic of image-based SNS.

The cognition of an intrinsic attribute play an important role in the process of theoretical generalization. It is the aim of this paper to study how the theoretical generalization is made. First of all, we suggest the What-if-only-strategy(WIOS) which is the strategy helping the cognition of an intrinsic attribute. And we propose the process of the theoretical generalization that go on the cognitive stage, WIOS stage, conjecture stage, justification stage and insight into an intrinsic attribute in order. We propose the process of generalization adding the concrete process cognizing an intrinsic attribute to the existing process of generalization. And we applied the proposed process of generalization to two mathematical theorem which is being managed in middle school. We got a conclusion that the what-if-only strategy is an useful method of generalization for the proposition. We hope that the what-if-only strategy is helpful for both teaching and learning the mathematical generalization.

This research is to assess the relationship Big Data attributes and disaster response process. The hypothesis are designed to form decision making between situation awareness and disaster response by defining major attribute of Big Data(Volume, Variety, Velocity, Complexity). It is proved whether there is a moderating effect in cause-and-effect relationship by visualizing Big Data. To test the hypotheses, it was conducted a questionnaire survey of civil servants in charge of disaster-related government employees, and collected 320 data(without 12 undependable responses). The research findings are suggested the attributes of accumulation, expandability, flexibility, real-time, analytical, combination of Big Data have a strong effect on disaster manager's situation awareness.

도서관 서비스 품질을 향상하기 위해서는 이용자의 요구를 파악하는 것이 무엇보다 중요하며 이를 위해 서비스 품질에 대한 속성을 분석하여야 한다. 그러나 많은 선행연구에서 서비스 품질 속성과 만족도와의 관계를 선형관계로 접근함으로써 서비스 품질 속성을 구분하지 않고 있다. 이에 본 연구는 서비스 품질에 대한 이원적 인식방법을 제시한 KANO의 3요인 이론을 적용하여 서비스 품질 속성과 만족도와의 관계를 비선형관계로 접근하여 서비스 품질 속성을 분석함으로써 이용자 관점에서 도서관 서비스 품질을 이해하고 구체적인 개선안을 제시할 수 있는 방법론을 제언하고자 한다.

The purpose of this study was to examine the image similarity, preference, and the attribute recognition using multidimensional scaling. The analyses were carried out by 5 spa destinations located in Choongchung area. The results were as followings: first, considering the image similarity, the image of Suanbo & Onyang and Dogo & Asan were similar except for the Yusung. Second, considering the attribute recognition, Yusung had a stronger attribute reflecting spa tradition when compared to other competitive spa destinations. Onyang showed a strong attribute of facilities. Dogo had a stronger point about use cost. Suanbo had relatively strong attributes in terms of facilities, customer service, and accessability. However, the water quality of spa destination and activities were not reflected in attribute recognition because these two attributes was farthest from the spa destination. Third, considering the preference of selecting spa destinations, package tourists had a strong preference about Yusung, individual tourists, family, incentive tourists prefer Suanbo, followed by Dogo and Yusung. Group tourists had a strong preference about Dogo.

본 논문에서는 컬러 영상과 깊이 영상으로부터 영상 전체의 정보를 활용하는 형판 정합 방법으로 특징을 추출하여, 사물의 속성을 인식하는 시스템을 제안한다. 본 시스템은 입력 영상으로부터 더 많은 정보를 얻기 위해 컬러 영상과 깊이 영상을 함께 사용하였다. 그리고 영상의 부분적인 정보가 아닌 전체 정보를 활용하는 형판 정합 방법을 사용하여 속성 인식률을 향상 시켰다. 본 시스템의 성능을 확인하기 위해 워싱턴 대학에서 제공하는 RGB-D 데이터 집합을 이용하여 다른 특징들 및 분류기와 비교실험을 진행하였고, 본 논문에서 제안하는 시스템의 높은 성능을 확인할 수 있었다.

본 연구에서는 현재 시중에 판매되고 있는 네 가지 휴대용 음원재생기를 자극물로 사용하여 제품 속성에 있어서의 차이가 사용자 경험의 여러 요소에 영향을 주는지 여부(가설 1)와 사용자의 정서적 반응이 사용자가 인식한 제품 특성에 의해 영향을 받는지(가설 2) 그리고 제품에 대한 전체적인 판단이 사용자가 인식한 제품 특성과 감성적 반응에 따라 달라지는지(가설 3) 실험을 통해 조사하였다. 실험결과 기능적 특성과 유희적 특성에 대한 인식 정도는 실험 참가자가 사용한 제품에 따라 서로 다르게 나타났으며, 사용자의 정서적 반응과 전체적인 선호도 또한 평가 제품에 따라 서로 다르게 나타남으로서 제품 속성에 의해 영향을 받는 것으로 분석되었다. 이와 함께 사용자 경험을 구성하는 요소들 간의 상호관계도 테스트하였는데, 사용자의 정서적 반응이 주로 제품의 기능적 특성에 따라 달라지는 반면 사용자의 전체적인 판단은 제품의 기능적 특성과 유희적 특성 모두에 의해 영향을 받고 있는 것으로 나타났다. 또 분석결과에서 밝혀진 한 가지 흥미로운 사실은 사용자의 정서적 반응이 전체적인 판단에 아무런 역할도 하지 않는다는 점이다.

As environment issues arise, environment-friendliness in convention industry has also been discussed. Guidelines are presented by government and convention organization to settle environment-friendly convention. However, these efforts focus on organizers and suppliers, lacking in understanding convention participants. This study tries to approach in perspective of convention participants to get useful information for environment-friendly convention. The research explores how they are aware of environment issues and accept environment-friendly convention attributes according to their cognition of environment. It also examines the relationship between those attributes and intention of participation according to their awareness of environment. The results shows that participants have high awareness about environmental issue and recognized high necessity for set up for specific action plan. They showed highest acceptance of venue followed by activity, transportation, food & beverage, and operation. High awareness group showed higher acceptance of environment-friendly convention attributes than low awareness group. 'Transportation', 'activity', and 'operation' among five attributes were examined to have significant effect on intention of participate environment-friendly convention in both groups.
