Purposes of this study were to apply and examine that the importance-performance analysis(IPA) could be a useful park management tool. The IPA is an easily-applied technique developed in marketing field to measure attribute importance and performance. It displays them simultaneously on a 4-quardrant action grid; therefore, park managers can upgrade current services and address marketing strategies for various user segments. The children's grand park was selected as a study are. Two different types of questionaires were utilized for data analyses. They were collected from one respondent by on-site distribution or by mail survey, because attribute importance and performance should be rated before and after visiting a park, respectively. Then, total data was segmented systematically by 2 variables-age and benefit sought. Action grids from order to meet the needs of each segment. Several comments on both data collection methods and segment variables selection were described to improve the IPA in recreation settings for future researches.

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.

This paper tackles the prevalent challenges faced by existing tourism route recommendation methods, including data sparsity, cold start, and low accuracy. To address these issues, a novel intelligent tourism route recommendation method based on collaborative filtering is introduced. The proposed method incorporates a series of key steps. Firstly, it calculates the interest level of users by analyzing the item attribute rating values. By leveraging this information, the method can effectively capture the preferences and interests of users. Additionally, a user attribute rating matrix is constructed by extracting implicit user behavior preferences, providing a comprehensive understanding of user preferences. Recognizing that user interests can evolve over time, a weight function is introduced to account for the possibility of interest shifting during product use. This weight function enhances the accuracy of recommendations by adapting to the changing preferences of users, improving the overall quality of the suggested tourism routes. The results demonstrate the significant advantages of the approach. Specifically, the proposed method successfully alleviates the problem of data sparsity, enhances neighbor selection, and generates tourism route recommendations that exhibit higher accuracy compared to existing methods.

본 연구는 아시아의 선진 국가로써 이에 따른 자동차 시장도 성숙 단계에 있는 일본과 한국의 수도권에 거주하는 소비자에게 소비자의 특성에 따른 저탄소자동차의 선택속성요인과 저탄소자동차 유형별 예상구입시기에 대해 온라인 설문 조사를 기반으로 비교 고찰하고자 하였다. 본연구의 결과 한국과 일본의 소비자 특성과 소비자의 저탄소자동차의 선택속성요인과의 차이분석을 살펴본 결과 한국의 경우 성별에는 차이가 없으며 연령별로 보았을 때 경제성에는 차이가 있으며 소득수준별로 보았을 때 안정성에 차이가 있는 것으로 나타났다. 이는 연령에 따라 저탄소자동차 선택속성요인이 나이가 들어감에 따라 차이가 있는 것으로 나타났으며 소득수준이 높아감에 따라 저탄소자동차 선택시 안정성을 더욱 중요하게 여기는 요인으로 보았다. 일본의 경우는 성별, 연령별, 소득별로 저탄소자동차의 선택속성요인에 차이가 없는 것으로 나타났다. 또한 한국과 일본 모두 저탄소 자동차 유형에 따른 향후 구매시기와의 연관성에 있어서는 차이가 없는 것으로 나타났다. 본 연구의 시사점 한국은 연령별로 보았을 때 경제적 측면을 중시하며 저탄소자동차를 선택하려는 경향이 있으며 소득수준별로 보았을 때 소득수준에 따라 저탄소자동차의 안전성을 중시하려는 경향이 있다는 의미 있는 결과를 얻었다 반면 일본의 경우 소비자특성별로 차이 없이 저탄소자동차를 선택하는 경향을 나타내고 있었다. 저탄소자동차의 유형에 따른 예상구매시기의 연관성은 한국은 저탄소자동차 유형중 향후 10년 이내에서 선호차량은 전기자동차를 선호하는 것으로 나타났으며 일본은 하이브리드 차를 선호하는 것으로 나타났다.

Purpose: The purpose of this study is to narrow the target down to college students representing single-person households to identify the main attributes of their choice of Home Meal Replacement(HMR) and to look at the impact on satisfaction and repurchase intentions. Research design, data and methodology: An online survey was conducted for consumers who purchased HMR products at least once and a total of 264 questionnaires were used for demonstration analysis. The collected data have verified for validity and reliability between measurement variables through exploratory factor analysis and reliability analysis. Results: As a result, curiosity, economy, safety, and brand, which are HMR selection attributes that university students' value, have a significant impact on satisfaction, and satisfaction has a significant impact on the intention of repurchase, a variable of behavior. In addition, the adjustment effect of health value pursuit was significant only in safety attributes. Conclusions: This study divided the target group to examine what the HMR selection attributes of single-person college students are, the main consumer of HMR, and how selective attributes affect satisfaction and willingness to repurchase. In the process, we wanted to find out if there was a moderating effect on the health-oriented values in the dietary lifestyle.

This paper presents a methodology to be able to select an appropriate RP system that suits the end use of a part. Evaluation factors used in process selection include major attributes such as accuracy, roughness, strength, elongation, part cost and build time that greatly affect the performance of RP systems. Crisp values such as accuracy and surface roughness are obtained with a new test part developed. The test part is designed with conjoint analysis to reflect users' preference. The part cost and build time that have approximate ranges due to cost and many variable parameters are presented by linguistic values that can be described with triangular fuzzy numbers. Based on the evaluation values obtained, an appropriate RP process for a specific part application is selected by using the modified TOPSIS(Technique of Order Preference by Similarity to Ideal Solution) method. It uses crisp data as well as linguistic variables, and each weight on the alternatives is assigned by using pair-wise comparison matrix. The ranking order helps the decision making of the selection of RP systems.

As the types of wedding ceremonies become diversified, and consumers' needs become more selective, greater importance is given to wedding planners' roles in the wedding industry, and consumers require differentiated types of wedding service. As a preliminary qualitative study in this field, an ethnographic study was conducted to identify factors valued by consumers when selecting a wedding planner in the wedding planner market, which has rapidly grown in recent years. An in-depth interview was performed with eight participants in terms of wedding planner utilization type and consumers' understanding of wedding preparation with a wedding planner. The collected data were analyzed through taxonomy, component analysis and decision table analysis; for validation, professional wedding planners were asked to review the items valued by consumers in selecting a wedding planner. Four factors - expense characteristic, wedding planners, wedding consulting companies, and customer characteristics - were identified, along with eight sub-factors (capability, service attitude, technical communication, personal factors, wedding planner encounter paths, spouse's satisfaction status, and companies). Out of these, price (within budget), wedding planners' capability, wedding planners' service attitude are expected to be meaningful in further research because they were found to be attributes commonly valued by every respondent. This study is significant in that it has made a new approach to understanding wedding planner selection attributes through ethnographic research and identified new wedding planner selection attributes.
