The objective of this study is to analyze domestic air passengers' preferences for selecting domestic airline company. By the analytic hierarchy process(AHP) method, we tried to measure the weight of the qualitative factors objectively and scientifically. The overall results indicate that domestic air passengers place more weight on airport service factor than other service factors for selecting domestic airline. Also, reservation/ticketing and in-flight service factors are equivalent to airport service factor. These priorities are differently shown followed by passengers' income. Therefore, airline companies need to formulate the differentiated strategy and customer-oriented marketing plan based on identified customer needs.

As interest in the high-potential Chinese beauty market is growing, understanding the disposition of Chinese consumers different from Korea is becoming more important for successful entry into the Chinese market. This study attempted to compare differences in beauty shop selection attributes between Korean and Chinese consumers. In order to achieve this research purpose, the beauty shop selection attribute was classified into five components: environmental attribute, structural attribute, external attribute, awareness, and service attribute. Survey responses were collected from 162 Chinese and 111 Koreans, respectively, and empirical analysis was conducted. Both Chinese and Koreans had significant relationships between environmental attribute, service attribute and satisfaction, but the relationship between the remaining attributes and satisfaction were not significant. In addition, significant differences exist between Chinese and Koreans in the relationship between environmental attribute, service attribute and satisfaction. The results of this study can help companies to establish and operate a higher quality beauty shop based on understanding the situation and characteristics of each country in the fierce competition in the beauty market.

본 논문에서는 신경망의 가중치와 정보이론을 이용한 속성선택 기법을 제안하였다. 제안된 방법은 정보이론의 상호정보량을 이용하여 각 속성들의 중요도를 평가한 후 중요도가 높은 속성들만을 선택하여 신경망의 입력으로 사용한다. 신경망의 입력으로 선택된 속성의 가중치에 대한 평가를 통하여 오차에 큰 영향을 미치는 속성들을 순차적으로 제거하여 가장 우수한 속성들을 구한다. 제안된 기법의 성능을 평가하기 위하여 다양한 패턴 분류 문제에 적용하고 그 성능이 우수함을 확인하였다.

In this study, the selection attributes of contemporary dance audience were constructed based on prior study and the selection attributes of contemporary dance performance were identified through EFA(Exploratory Factor Analysis). Therefore, Six attributes were derived: physical evidence, tickets, people, information, product, and reputation. Based on these attributes, the selected attributes were identified through 'ETPB(Extended Theory of Planned Behavior)' to see if they affect ticket purchase behavior. In result, Among the selection attributes of contemporary dance performances, three attributes of reputation, people and product influenced the audience's attitude, while only product and human attributes influenced the purchase intention of tickets. Among the variables of ETPB to enhance the ability to purchase intention of tickets, audience attitude, perceive behavior control, and prior knowledge have had a positive effect on purchase intention of tickets, except for subjective norm. Therefore, it is meaningful that this study presented and verified empirically the attributes of select centered on visitors, which can improve the intention of purchasing tickets for contemporary dance performances.

A data stream is a massive unbounded sequence of data elements continuously generated at a rapid rate. Query processing for such a data stream should also be continuous and rapid, which requires strict time and space constraints. In most DSMS(Data Stream Management System), the selection predicates of continuous queries are grouped or indexed to guarantee these constraints. This paper proposes a new scheme tailed an ASC(Attribute Selection Construct) that collectively evaluates selection predicates containing the same attribute in multiple continuous queries. An ASC contains valuable information, such as attribute usage status, partially pre calculated matching results and selectivity statistics for its multiple selection predicates. The processing order of those ASC's that are corresponding to the attributes of a base data stream can significantly influence the overall performance of multiple query evaluation. Consequently, a method of establishing an efficient evaluation order of multiple ASC's is also proposed. Finally, the performance of the proposed method is analyzed by a series of experiments to identify its various characteristics.

As increased demand for well-being food caused more interest in hangwa, or Korean traditional sweets and cookies, this study attempted to analyze the effects of psychological well-being awareness on selection attributes for it and customer satisfaction based on the customers who buy hangwa. As a result of statistical analysis, psychological well-being awareness positively affects selection attributes for hangwa. It also bas a positive effect on customer satisfaction.

설계자는 설계를 진행시켜 가면서 많은 의사 결정을 내려야 한다. 그 결정은 크게 선택 결정과 타협 결정으로 나뉘어질 수 있다. 선택 결정은 여러 평가 기준을 고려해 여러 대안들 중 하나를 선택하는 결정이며 타협 결정은 제한 조건과 목표들을 가장 잘 만족하는 설계 대안의 주요 치수를 결정하는 것이다. 이때 두 결정의 결과는 설계자의 의사에 크게 의존하게 된다. 따라서 설계자의 의사를 체계적이고 정확하게 반영시켜줄 필요가 있다. AHP 기법은 불분명한 선택 문제에 있어서 문제를 계층적으로 분석하여 평가함으로써 설계자의 의사를 체계적으로 반영시켜줄 수 있다. 또한 정성적인 성질들을 정량적인 판단 기준에 따라 평가함으로써 설계자의 의사를 보다 일관적으로 반영할 수 있다. 보통 공학 문제의 경우 하나의 설계 대안을 선택하고 또한 그 대안의 주요 치수를 동시에 결정해야 하는 결합된 문제이다. 이때 선택에 필요한 각 대안의 속성이 타협 문제 변수들의 함수로 표현되기 때문에 최적 과정 중에 계속 변화하게 된다. 또한 여러 속성을 고려할 경우 자릿수와 단위가 모두 다르기 때문에 속성들의 평가가 표준적으로 이루어져야 한다. 이 부분에 학습된 인공 신경망을 도입함으로써 변화하는 속성치를 자동적으로 평가할 수 있으며 설계자의 의사와 경험적인 지식도 반영할 수 있게 되었다.

전 세계적으로 저비용항공사의 항공운송시장 참여로 승객들의 항공사 선택이 다양화 되었으며, 우리나라도 2011년 현재 5개의 저비용항공사가 시장에 참여하여 기존 국적항공사와 경쟁을 하고 있다. 본 연구는 우리나라 항공사 승객이 항공사 선택 시 중요하게 생각하는 속성을 파악하고, 저비용항공사 승객과 기존 국적항공사 승객이 항공사 선택 시 중요시 하는 속성의 중요도와 만족도 차이를 분석하는데 목적이 있다. 저비용항공사와 기존 국적항공사 승객을 대상으로 설문을 실시하여 항공사 선택 속성을 파악하고, 차이분석, 중요도-만족도 분석, t-test를 활용하여 항공사 선택 속성의 차이를 분석하고 국적항공사와 저비용항공사의 항공사 선택속성 중요도와 만족도 차이를 분석하고자 한다.

The implicit assumption of port selection studies based on survey and respondents' perceptions is that the preference of the port selection attributes is proportional to the selection behavior. Further, the straight lines of the port selection attributes could also have non-linear properties. This study confirms nonlinear characteristics of selection attributes by using Kano model. The findings of this study showed that several properties of carriers were evaluated as nonlinear characteristics, such as the intermodal links and network accessibility, and size of port and terminal. Hence, port service providers such as port authorities and terminal operating companiesl, should construct a port operation strategy that reflects the non-linear port selection characteristics of shipping companies. Since this study aimed at exploring the forms of port selection characteristics, long-term additional verification studies on ports and stakeholders at domestics and abroad were needed. The Kano model and importance-selection analysis method used for analysis and strategy establishment also need to be improved to capture evident characteristics and to present strategic guidelines.

In this study, the factors of customers' selection attributes on family restaurants, brand images, and the effect on revisit intention were analyzed. Specifically, the effects of brand, store, and price, which are sub-factors of family restaurants, on customers' revisit intention, store/service value, brand value, food effect, and revisit intention were examined. Among the brand image and four family restaurant selection attributes derived from this study, the most significant selection attributes were the cleanliness and hygiene of family restaurant stores and the menu and quality of family restaurant stores. Therefore, it can be said that family restaurants are price attributes and store/service attributes that have the most influence among the selection attributes. Through this, we intend to provide basic data necessary to find development plans through strategic plans for family restaurant management in the future.
