현재 국내외적으로 다양한 강재 댐퍼의 형상에 대한 연구가 이뤄지고 있다. 강재 댐퍼는 제진장치 중 하나로 항복을 통해 지진에너지를 흡수 및 소산하여 본 구조물을 보호한다. 최근 적용되고 있는 면내 전단 변형에 의해 작동하는 댐퍼는 응력이 특정 부위에 집중되어 재료의 대부분이 본래의 역량을 발휘하지 못하는 한계가 있었다. 따라서, 본 연구에서는 이 한계를 극 복하고자 전역 최적화 기법 중 하나인 뻐꾸기 탐색을 적용해 최적 형상을 설계하였다. 탐색된 최적 형상을 토대로 수치해석과 실제 실험을 통한 성능검증을 수행했다. 최적 형상으로 설계된 댐퍼는 안정적인 이력거동을 보이고, 높은 에너지 소산능력을 확 보하는 것으로 나타났다. 본 연구에서는 전역 최적화 기법을 적용한 최적 설계 방법을 제시하고 그 결과를 검증함으로써, 다양한 형태의 공학적 문제 해결에 대한 적용 가능성을 제시하였다.

최근 농업분야에서 정밀농업을 구현하기 위한 다양한 노력들을 기울이고 있다. 정밀농업분야에서 가장 대표적인 연구분야는 영상정보를 이용하여 작물의 생육 및 수량을 예측하는 것이다. 특히, 여러 영상정보 중에서 다중분광 혹은 초분광영상정보를 기반으로 한 작물의 생육 및 수량예측이 가장 활발하게 연구되고 있는 분야이다. 각각의 센싱장비를 통해서 획득된 영상정보는 여러 방법으로 활용할 수 있으며, 가장 보편적으로 활용하고 있는 방법이 다중분광 및 초분광정보를 이용하여 다양한 식생지수로 산출하고 이를 기반으로 작물의 생육을 예측하는 것이다. 식생지수는 식물체내의 광합성색소함량 및 광합성효율과 높은 상관관계를 보이는 파장을 기반으로 산출된 지수이다. 현재까지 약 150종의 식생지수가 알려져 있으나 농업분야에서 주로 이용하고 있는 식생수는 일부에 불과하다. 이런 이유에서 본 논문에서는 다양한 식생지수들 중 주요한 식생지수들을 선별하여 식생지수들의 산출공식, 적용방법과 관련된 내용을 소개하였다.

The aim of this study was to determine the therapeutic effects of beauty care on negative mental health, including stress and depression. Nail care, massage care, and makeup were used as programs for beauty therapy. Qualitative research was conducted with six female participants over five-month period. After interviewing the subjects in advance, beauty care treatments were performed every week 4 weeks in the following order: nail care, massage, and makeup. The results are as follows, First, the participants perceived beauty care in the form of 4 concepts: “courtesy in social life,” “investment in oneself,” “self-satisfaction,” and “self-care.” Second, the effects of beauty therapy were categorized as “psychological effects,” “confidence,” “behavioral changes,” “evaluation of others,” and “positive social effects.” Third, each subject showed different psychological effects during the process when the function of the therapy took effect through the beauty care treatment. It was confirmed that confidence levels increased as a result of treatment through the process of becoming re-aware of oneself. Positive statements from the participants included: “I want to go out,” “I have become kind and positive to others,” “I have become more active in a given task,” and “It seems that my work ability is improving.” Finally, t-test results for selfesteem, depression, and stress showed there were significant differences in self-esteem and depression. This confirmed that self- esteem increased, and depression decreased after the beauty care treatment.

The purpose of this study is to identify the relationship between experience marketing using makeup services and theme park users’ satisfaction, loyalty, and revisit intention. This is because it can identify the usefulness of makeup services and provide implications for effective field marketing strategies. In order to achieve the purpose, 668 users of the theme park were surveyed after convenience screening as research participants. The main theme was the makeup service for visitors to Lotte world, Everland, and Hapcheon Ghost theme park. this study reviewed previous studies and applied them to the makeup service. Based on this, the research model and the hypothesis were established, and as part of the empirical research, the hypothesis was verified through analysis methods such as frequency analysis, reliability verification, factor analysis, and structural equation modeling. The summary of the research results based on empirical analysis is as follows. First, as a result of analyzing experience marketing using makeup services has a positive impact on the satisfaction of customers using theme parks. Second, experience marketing using makeup services has a positive effect on customer loyalty. Third, experience marketing using makeup services has a positive effect on intention to return. Fourth, satisfaction and loyalty were found to affect the intention to return. Based on this research, we hope that the makeup service as experiential marketing can be effectively applied in various fields, and that the research can be used as basic data to make the makeup service into the representative cultural contents marketing.
