Bitcoin is a blockchain technology-based digital currency that has been recognized as a representative cryptocurrency and a financial investment asset. Due to its highly volatile nature, Bitcoin has gained a lot of attention from investors and the public. Based on this popularity, numerous studies have been conducted on price and trend prediction using machine learning and deep learning. This study employed LSTM (Long Short Term Memory) and CNN (Convolutional Neural Networks), which have shown potential for predictive performance in the finance domain, to enhance the classification accuracy in Bitcoin price trend prediction. XAI(eXplainable Artificial Intelligence) techniques were applied to the predictive model to enhance its explainability and interpretability by providing a comprehensive explanation of the model. In the empirical experiment, CNN was applied to technical indicators and Google trend data to build a Bitcoin price trend prediction model, and the CNN model using both technical indicators and Google trend data clearly outperformed the other models using neural networks, SVM, and LSTM. Then SHAP(Shapley Additive exPlanations) was applied to the predictive model to obtain explanations about the output values. Important prediction drivers in input variables were extracted through global interpretation, and the interpretation of the predictive model's decision process for each instance was suggested through local interpretation. The results show that our proposed research framework demonstrates both improved classification accuracy and explainability by using CNN, Google trend data, and SHAP.

E-commerce is gradually upgrading from traditional text and image formats to short video and livestreaming formats. Livestreaming e-commerce enriches the content and forms of information dissemination and product display, enhances the consumer's shopping experience, and gradually becomes the mainstream new consumer scene. However, there are many negative phenomena in the development of livestreaming e-commerce, such as false propaganda, counterfeit goods, and various negative events, which seriously affect the level of consumer trust in livestreaming e-commerce. Trust is the core competitive factor of livestreaming e-commerce. Based on previous research on trust theory and combined with the characteristic elements of "people, goods, and scenes" of livestreaming e-commerce, this article constructs a trust model for livestreaming e-commerce, proposes hypotheses, and proves through empirical research that factors such as store characteristics, livestream host characteristics, brand image, product information, platform reputation, livestreaming situation, and trust tendency have a significant positive impact on consumer trust. Based on the research conclusions, this article provides insights and management suggestions, such as emphasizing the construction of store characteristic indicators, creating desirable livestream host characteristics, focusing on product brand building and selection, maintaining the display of product information, selecting suitable livestreaming platforms, and creating rich content for livestreaming situations.

The purpose of this study is to set the Korean mandarine quality standards based on consumer preference survey. Until now the Korean mandarine's quality standards has been based on the fruit size. The Korean mandarine's quality in agricultural cooperative, citrus agricultural cooperative federation, and some agricultural corporation has been selected in accordance with its own brand of quality grade using a non-destruction sorting machine. But, setting the Korean mandarine's quality standards has been based on the convenient and routine method rather than the scientific and objective method, consumer's preference. According to the grade contents, the highest grade brand was required more than sugar $12^{\circ}Bx$ and less than acid 1.0% and the following grade brand was required more than sugar $11^{\circ}Bx$ and less than acid 1.0% uniformally. Thus, in this study, based on the consumers' preference of Korean mandarine, 4-level grades of sugar and 4-level grades of acidity were divided into the total 16-level grades. Based on them, 5-level grades were set.

오늘날 화장품 산업은 역동적으로 끊임없이 변화하고 있다. 화장품은 한 사회 구성원들의 다양한 욕구, 가치관 및 생할양식에 영향을 미치며 심지어는 국가의 정치적 기후나 경제적인 상태를 나타내는 지표역할을 담당하기도 한다. 즉, 화장품 과학은 예방의학, 건강과학이라는 차원에서 뿐만 아니라 미적인 차원에서 새로운 상품개발이 진행되어갈 것이다. 지금 우리는 21세기를 향하여 1990년대의 중반기에 들어섰다. 80년대는 물질 문명의 중심으로 생활의 질의 풍요로움을 추구하였으나 90년대는 소비자 우선의 풍요로움을 향수하는 시대가 되었다. 또한 여성이 사회진출, 고령화의 급속한 진전, 고 학력화, 개인의 가치관 존중 및 많은 생활패턴의 변화가 마음의 풍요로움을 구하는 사람들이 늘어나고 물질적 의존도로 부터의 탈피가 크게 강조되고 있다. 이에 마음의 풍요로움을 창조하여 연출하는 화장품산업의 역할이 고기능성에 의한 부가가치를 높이고 마음의 풍요로움을 지원하기 위한 연구개발에 중점을 두고 진행되어 가고 있다. 화장품을 여성들의 치장이라고 하는 주체적 행위에 도움을 주는 하드웨어라고 한다면 소비자의 마음은 소프트웨어로써 소비자 입장에서 만족할 수 있는 전략을 구사하는 아이디어가 있어야 하는데 그에 상응하는 대책으로 스킨케어를 들 수 있다. 스킨케어란 병든 피부를 제외한 여러 가지 유형의 피부를 화장품과 미용기기를 이용하여 그에 맞게 예방관리 하여 건강하고 아름답게 보호 유지하는 전문 분야이다. 즉, 스킨케어는 화장품 이용을 통하여 미래의 소비자들의 다양한 비용 욕구 및 소망에 효과적으로 대응할 수 있는 소프트웨어라고 할 수 있다., 또한 스킨케어는 화장품 뿐만 아니라 신체적 접촉을 통하여 안위를 제공하는 수단으로 단순한 피부손질이라는 문제에 그치지 않고 접촉을 통해 마음과 신체의 균형을 꾀하는 생명현상의 심층과 연관되는 중요한 의미가 있다. 스킨케어는 불어로 Soin Esthetique 라고 하는데 어원을 보면 손질, 처치, 보살핌 그리고 배려를 의미한다. 지금으로부터 200년전 독일의 미학자인 Baumgarten이 미는 인간에게 만족과 쾌감을 주는 대상이며 미는 보는 사람의 마음에 있다라는 감성의 미학에서 Esthetique라는 단어를 처음 사용했다. 다시 말하면 Soim Esthetique는 인간의 마음 만족과 쾌감을 주는 배려 있는 조치로써 여성이 화장을 함으로써 외모의 조화에서 마음과 신체의 균형을 꾀하는 생명현상의 심층과 연관되는 것과 마찬가지로 에스테틱과 화장의 심리는 매우 땔래야 땔 수 없는 불과분의 밀접한 관계라 볼 수 있다.
