BACKGROUND/OBJECTIVES: This research was conducted to compare lecture- and experience-based methods of nutritional education as well as provide fundamental data for developing an effective nutritional education program in elementary schools. SUBJECTS/METHODS: A total of 110 students in three elementary schools in Jeollanam-do were recruited and randomly distributed in lecture- and experience-based groups. The effects of education on students' dietary knowledge, dietary behaviors, and dietary habits were analyzed using a pre/post-test. RESULTS: Lecture- and experience-based methods did not significantly alter total scores for dietary knowledge in any group, although lecture-based method led to improvement for some detailed questions. In the experience-based group, subjects showed significant alteration of dietary behaviors, whereas lecture-based method showed alteration of dietary habits. CONCLUSIONS: These outcomes suggest that lecture- and experience-based methods led to differential improvement of students' dietary habits, behaviors, and knowledge. To obtain better nutritional education results, both lectures and experiential activities need to be considered.

최근 경험데이터에 대한 중요성이 커지면서 데이터사이언스적 관점으로 경험데이터를 다루려는 시도가 많아지고 있다. 빅데이터와 같은 수치적으로 계량화하려는 정량(quantitative)적 조사 방식의 수집방식으로 접근하는 경우에 경험이 가지고 있는 가치에 대한 폭넓은 해석이 어려울 뿐 아니라 비용, 시간이 상대적으로 많이 들고, 개인정보 침해의 위험으로 분석에 한계가 있다. 하지만, 정성(qualitative)적 조사 기반의 경험데이터 수집 절차인 에스노그라피(ethnograpy)는 사용자라는 관점에서 미래 고객의 자연스러운 실제 환경에서 주로 실시되기 때문에 적은 표본으로도 고객이 직면한 본질을 확인할 수 있고, 경험데이터가 가지고 있는 맥락적 차원의 관계를 해석하기에도 용이하다. 에스노그라피 방식의 경험데이터 수집이 경제적이고, 효율적이라고 하여도 데이터의 수집 과정에 대한 과학적 절차의 미흡은 문제가 될 수 있기에, 수집과정의 오차를 줄이는 것은 중요하다. 에스노그라피 방식의 경험데이터 수집에 대한 올바른 측정 도구를 사용했느냐에 대한 타당성 확보와 측정대상을 정확하게 선정하여 타당성 있는 측정 도구와 방법을 사용했느냐의 신뢰성 확보가 중요하다. 이러한 관점에서 에스노그라피 방식의 경험데이터 수집에 대한 올바른 측정 방법과 도구개발을 위해 타당성을 확보하고 측정대상을 명확하게 선별하는 연구방법의 신뢰성을 검증할 필요가 있다. 이에 본 연구에서는 에스노그라피 방식의 경험데이터 수집에 기반하여 자영업자의 고객경험을 분석해주는 'I know you_AI' 서비스의 데이터와 방법론 사례를 중심으로 이에 대한 검증 연구를 진행하였고, 연구 결과 신뢰성과 타당성이 있음을 확인하였다.

Currently, museums and architectural heritage provide augmented user experiences by incorporating various media technologies. They still, however, suffer from the limitation of entertainment-based and the provision of location-based simple and repetitive contents. In addition, while acting as a key medium of experience for architectural heritage, the concept of space is not properly reflected in current services. The purpose of this study is to design user space experience considering such characteristics of architectural heritage. The spatial experience content and content production platform are defined. This software platform creates content that enhances the experience of the place by giving a context-based digital data associated with space and objects. The spatial experience content is designed as a series of experience sequences. The composition of the sequence borrows the method of film and narrative which segment and connect consecutive experiences on a scene basis considering user's detailed spatial experience. Therefore, content components can be combined and reproduced in various types. Augmented contents were extracted by using rule-based reasoning function of ontology at the moment. As a practical example of architectural heritage, the Seokjojeon Hall is used to reveal a spatial experience scenario.

Generally, building construction projects have a complex decision-making process because of the participation of various agents. In this situation, a final decision is arrived at by relying on subjective judgments based on the experience of project participants. For this reason, a method of assessing the objectivity of opinions is needed. In previous studies, the multi-criteria decision making method was applied to arrive at a final decision objectively, but this method has a limitation, in that the experience of each decision maker is not considered differently in the decision making process. Therefore, this study proposed a theoretical model using the S-shaped growth curve and regression analysis by building construction project type to quantitatively estimate decision-making reliability according to the experience of individual project participant`s. The developed model could be added to the Multi-criteria decision making method, and secure the objectivity and reliability of project participants' final opinion.
