공간 데이터는 복합적인 속성들의 조합으로 이루어지며 연산 또한 복합적이라는 점에서 일반 데이터와 다른 특성을 갖는다. 따라서 공간 데이터는 일반 속성 데이터와 구별되는 파일이나 별도의 저장 구조를 사용하여 관리되어야 한다. 이것은 비공간 데이터와 공간 데이터간의 상호 동기화 문제와 트랜잭션의 처리 등에서 많은 문제점을 발생시키며 이를 해결하기 위해서는 공간 데이터와 비공간 데이터를 단일 데이터베이스화하여야 한다. 이 논문에서는 이러한 단일화된 데이터베이스 시스템을 지원하기 이한 공간 객체-관계 데이터 모델을 정의하고 이 모델을 구현하기 위한 타입 저장 방법들에 대해 기술한다.

The opinion of user on a certain product is expressed in positive/negative sentiments for specific features of it. In some cases, they are expressed for a holistic part of homogeneous specific features, or expressed for product itself. Therefore, in the area of opinion mining, name of opinion features to be extracted are specific feature names, holonyms for theses specific features, and product names. However, when the opinion target is described with product name or holonym, sometimes it may not match feature name of opinion sentence to true opinion target intended by the reviewer. In this paper, we present a method to extract opinion targets from opinion sentences. Most importantly, we propose a method to extract true target from the feature names mismatched to a intended target. First, we extract candidate opinion pairs using dependency relation between words, and then select feature names frequently mismatched to opinion target. Each selected opinion feature name is replaced to a specific feature intended by the reviewer. Finally, in order to extract relevant opinion features from the whole candidate opinion pairs including modified opinion feature names, candidate opinion pairs are rearranged by the order of user's interest.

본 연구는 두 가지 선물상황(생일, 크리스마스)과 선물수용자(가족, 친구)에서 성별에 따라 선물 속성지각에 차이가 있는지를 밝히고자 하였다. 질문지를 이용하여 미국 남녀 비자 97명을 대상으로 자료수집 하였으며, 자료분석을 위해 MANOVA(Multivariate Analysis of Variable)를 실행하였다. 분석결과, 가족과 친구를 위한 생일선물상황에서 성에 따라 쾌락적 속성(독특한, 유행하는, 재미있는)의 중요성 지각에 차이를 보여 여성이 남성보다 선물의 쾌락적 속성을 더 중요하게 지각하였다. 또한 가족과 친구를 위한 크리스마스 선물상황에서도 성별에 따라 쾌락적 속성에 차이를 보여 여성이 남성보다 가족을 위한 선물로써 독특한, 유행하는 속성을 더 중요하게 지각하고, 친구를 위한 선물은 독특한, 재미있는 속성이 더 중요하게 지각되었다. 그러나 실용적 속성(내구성있는, 실용적인, 비싸지 않은)에서는 두 가지 상황의 가족과 친구를 위한 선물지각에 대해 성별에 따라 유의한 차이를 보이지 않았다. 따라서 본 연구결과. 소비자들은 선물구매상황에서 일반제품과 달리 쾌락적 가치를 더욱 중요하게 인식하고 있으며, 성별에 따라 선물 상황과 수용자에 대한 선물의 쾌락적 속성지각에 차이를 나타냄으로써 성별에 따른 차별화된 선물상품개발 및 이미지 포지셔닝 전략을 통해 효과적 마케팅 관리가 이루어져야 할 것이다.

영한 기계변역에서의 전치사구 처리는 자연어 처리의 중요한 연구과제 중 하나이다. 특히 전치사구의 격의미는 그에 대한 한국어 표현에 중요한 실마리가 된다. 본 논문은 영어의 전치사구에 대한 한국어 표현을 선택하기 위한 격의미 체계를 정의하고 그 격의미 체계를 실험한다. 이 격의미 체계는 전치사구에 대한 한국어의 격의미를 분별함으로 보다 좋은 한국어 격조사를 선택하게 해준다. 본 논문에서는 각 격의미의 구분을 위한 의미속성 집합도 정의한다. 이 의미속성 집합은 WordNet의 시소러스에서 제공한 상하위 관계와 변환표를 근거로 자동적으로 추출된다. 의미속성 집합의 자동획득은 격의미 체계의 표현과 기계변역의 성능 평가에 일반성을 부여한다. 격의미 체계와 의미속성 집합의 자동 획득은 영한 기계변역은 물론 한국어 생성과 자연어 처리에 중요한 기여를 할 것으로 보인다.

Smart car is a vehicle which maximizes convenience, safety, and user experience. The traditional vehicle style will be replaced by a smart car. The objective of this paper is to find essential quality attributes that consumers want. We provide a method to select a best smart car reflecting their preference based on the quality attributes. We derive Kano's quality attributes by an exploratory survey and show an example to implement their decision using the Analytic Hierarchy Process method. As a result, the quality attributes were classified into two groups of attractive quality and indifference quality. The respondents evaluated that the safety of smart cars was more important than the convenience and user experience. However, the smart car was required more functions related to the convenience criteria. These results will provide important implications for smart car design.

The derivation of optimal information from decision table is based on the concept of indiscernibility relation and approximation space in rough set. Because decision table is more likely to be susceptible to the superposition or inconsistency in decision table, the reduction of attributes is a important concept in knowledge representation. While complete subsets of the attribute's domain is considered in algebraic definition, incomplete subsets of the attribute's domain is considered in information-theoretic definition. Therefore there is a marked difference between algebraic and information-theoretic definition. This paper proposes a conditional entropy using rough set as information theoretical measures in order to deduct the optimal information which may contain condition attributes and decision attribute of information system and shows its effectiveness.

With the continuous progress and development of the social economy, the importance of commodity packaging is increasingly manifested. It has become an important form of communication between businesses and consumers, and an important means of competition between businesses. The research scope of the thesis: First, through literature investigation, analyze the function of packaging design and consumers' buying attitude, and analyze the name, color, logo, illustration, etc. for general chocolate packaging and travel souvenir chocolate packaging. Research method: Through questionnaire survey, according to consumers' purchasing attitude and personal value of package design, we have in-depth understanding of consumers' purchasing power and package design's influence on purchasing conditions and research. According to the results of this study, first, from the perspective of general chocolate packaging and travel souvenir chocolate packaging to consumer consumption phenomena, general chocolate is more popular. Second, when consumers buy products, the taste of chocolate is more important than product packaging design. Third, in each product group, consumers value their own value when buying chocolate products. Fourth, due to the two important attributes of packaging design and taste, ordinary chocolate has a higher purchase intention than travel souvenir chocolate.

This study proposes the metaverse content production pipeline using ZEPETO World, one of the representative metaverse platforms in Korea. Based on the Unity 3D engine, the ZEPETO world is configured using the ZEPETO template, and the core functions of the metaverse content that enable multi-user participation such as logic, interaction, and property control are implemented through the ZEPETO script. This study utilizes the basic functions such as properties, events, and components of the ZEPETO script as well as the ZEPETO player which includes avatar loading, character movement, and camera control functions. In addition, based on ZEPETO's properties such as World Multiplayer and Client Starter, it summarizes the core synchronization process required for multiplay metaverse content production, such as object transformation, dynamic object creation, property addition, and real-time property control. Based on this, we check the proposed production pipeline by directly producing multiplay metaverse content using ZEPETO World.

The purpose of this study was to investigate if there are any differences of convention advertising and participation behavior based on the segmented groups of convention advertising attributes. The research methods and contents of this study are as follows. From the literature, the measurement of convention advertising attributes, satisfaction, and participation behavior had been developed and utilized to collect the data. The results of factor analysis showed three underlying dimensions of convention advertising attributes. Cluster analysis showed that there were three different segmented groups such as negative, mediative, and positive groups of convention advertising attributes. Lastly, MANOVA showed that there were differences of convention advertising and participation behavior among the segmented groups. More theoretical and practical implication are discussed in the conclusion.
