With the prolonged Covid-19 epidemic, movement restrictions such as social distancing are prolonged, and as people stay indoors for a longer time, interest in indoor air pollution is increasing. Indoor air quality is not easily purified unlike outdoors. Among indoor building materials, paints and flooring contain formaldehyde that causes sick house syndrome and VOCs that contain carcinogenicity and harmfulness. For modern people who spend a lot of time living indoors for more than an hour, the occurrence of these harmful substances can be said to be fatal. In response to these risks, in July 2019, the government reinforced the standards for indoor air quality to protect the public's health by raising the detection standards for fine dust, ultrafine dust, and formaldehyde in indoor multi-use facilities. People use machines such as air purifiers to improve indoor air quality, or make efforts such as periodic ventilation. In order to reduce or support these other ancillary efforts more effectively, to reduce the generation of pollutants in the building itself, or to adsorb or purify pollutants in the air, use carbon black as an admixture to make a cement hardened body, and to grasp basic physical properties and adsorption capacity. And the result is as follows. As a result of the experiment to determine the appropriate amount of carbon black, it was confirmed that the more the amount of carbon black was added, the better it was in the formaldehyde emission test, but the tendency was not clear when measuring the flexural strength, so a further experiment to improve this is needed.

In order to solve problems such as acceleration of resource use and environmental pollution, experiments were conducted with the aim of producing indoor finishing materials that can adsorb fine dust and carbon dioxide using gelite and polymer, which are porous materials. Based on the previous experiment, gelite was substituted at each level in a matrix having a polymer S738P substitution rate of 12.5%, and the results are as follows. As the substitution rate of gelite increased, the amount of fine dust and carbon dioxide adsorption increased, which is believed to be due to physical adsorption due to the high porosity of gelite. However, further experiments are needed as the overall adsorption amount is not high due to the filling inside the matrix due to the polymer.
레스토랑에서 맞춤형 서비스 디자인 연구- 애플리케이션 중심으로

과학과 문명의 발달로 산업구조가 확대되면서 가정 밖에서 식사하는, 즉 외식의 기회가 증가하고 외식 형태가 다양화, 세분화되어 왔다. 현재 레스토랑들은 차별성 있는 서비스를 제공하여 고객들을 끌어들이기 위해 여러 가지 대안이 나오고 있지만 단기성과 한정적인 이벤트성의 서비스만이 보여주는 실정이다. 또한 외식사업과 관련된 애플리케이션이 시중에 많이 나와 있지만 레스토랑 내에서 고객과 레스토랑이 실시간 쌍방향 커뮤니케이션을 이루지 못하고 있어 레스토랑 안에서 고객 맞춤화 서비스를 제공할 수 있는 애플리케이션을 연구하고자 한다. 우선, 우리나라 외식문화에 대해 알아보고, 모바일 시장 현황을 살펴본 뒤, 고객이 레스토랑에 들어가서 나올 때까지 받는 서비스들을 분석해 개선할 부분을 도출해 내 고객들의 잠재적인 니즈를 해결책을 제안하였다. 또한 향후 레스토랑 서비스의 한계점 제시와 기대효과를 결론으로 레스토랑 서비스디자인의 발전을 모색해보고자 한다. Industrial structure was expanded with the development of science and civilization. While increasing the opportunity of eating out, eating out forms, diversification has been broken. Restaurant to lure customers by providing differentiated services, several alternatives are emerging. However, showing only limited short-term performance of service events. Also associated with the restaurant business, there are a lot of applications on the market but customers within the restaurant and the restaurant unable to achieve real-time interactive communications. So I want to study the application can provide the customization service inside the restaurant. First of all, learning about the culture in the country eating out. and after examining the status of the mobile market. Receiving service customers go out to a restaurant until analysis. Customers` potential needs and areas for improvement to derive a solution is proposed. It also presents the limitations of the future restaurant service. To explore the development of a restaurant, service design to the conclusion that the expected effects.
사용성을 고려한 가정용 가습기 디자인 개발에 관한 연구
이전미(Junmi Lee) 한국HCI학회 2013 한국HCI학회 학술대회 Vol.2013 No.1
현대사회에 가전제품들은 사람들에게 편리성을 제공하기 위해 만들어졌다. 그 중 가습기는 과거부터 공간의 습도를 조절해 사람들이 바이러스나 세균에 면역력이 좋게 만들어주고 수분이 필요한 모든 생물들에게 도움이 되는 제품이었다. 이런 가습기 제품은 다양한 종류로 시장에 출시되고 있는데 가열식, 초음파식, 복합식, 자연식 네 가지 방식으로 습도를 조절한다. 그러나 가습기 살균제가 가습기가 사람의 건강을 도우는 제품이라는 인식에서 건강을 해치는 제품으로 변한 요인이 되고 있다. 가습기 살균제는 먼지 및 세균 번식이 잘 일어나는 초음파 가습기 내부의 청소용으로 사용되어 왔었는데 사용하게 되면 원인 미상의 폐 손상이 발생할 확률이 높아지고 사망자까지 나타나 큰 화두로 대두되자 사람들이 가습기에 대한 이미지가 나빠져 더 이상 구입하지 않는 모습을 보였다. 이에 따라 가습기 살균제를 사용할 필요가 없고 청소하기 편하게 디자인을 한다면 사람들이 가습기에 대한 인식도 달라질 것이라고 생각해 자연식 가습기를 중심으로 가습기 조형성 및 은유적 표현 방법을 살펴보고 발전방향을 모색하고자 한다. In modern society, the consumer products were made in order to provide convenience to people. Humidifier from the past to adjust the humidity of the space so people"s natural immunity to the virus or bacteria makes good. Also to all species of water needed was a product that will help. Humidifier to the various types of products on the market. Humidity control in four ways: heating, ultrasonic, combination, air washers. However, humidifier disinfectant change was recognized as unhealthy products. Humidifier disinfectant has been used in the cleaning of the humidifier inside because there are dust and bacteria breed well. If you used a humidifier disinfectant, you would increase the likelihood of lung injury of unknown cause. Deaths represented emerged as a big issue so people who have a bad image for the humidifier appearance do not have to buy anymore. Therefore, I want to design easier to clean the humidifier and you do not need to use a humidifier disinfectant. So, I find direction of development that air washers humidifiers considering formative and usability.
