A dormitory is the most important compound space to college students who have to live with others. Also, for the students living in the boarding area, the dorm space can be the space for learning, exchanges and cultural. These Housing environment is a public space, so this is based on Universal Design. However, the 1970s-built dormitory space for the current user is narrow and not right for furniture standard. In this study, in order to compensate for these problems, the design directions are based on the previous studies - Park, Young-Soon, 2008, 'A Proposal on Dormitory Furniture Design for University Students.' Based on the previous study, the type of variable design is designed for desks, bookcases, beds, wardrobes, and other cabinets as representative household types. Furthermore, these furnitures are assembled and transformed depend on the dormitory space for single, double and four students. The furniture assembly system and arrangement module are presented in the direction of three kinds of designs. Therefore, three meaning of this study are the development of design to be used each item, the realization of custom furniture for space and presenting variable design module.

Single-person households are steadily increasing every year, and unlike multi-person households, the incidence of depression is higher because they are mentally isolated. There are many causes of depression, including physical activity, family size, and stress. Less physical activity and more stress are associated with higher rates of depression. As the number of single-person households increased, and the COVID-19 outbreak in 2019 caused restrictions on physical activity due to the overlapping pandemic, the stress index increased, resulting in many depressed patients. Since many patients do not receive treatment even if they develop depression, we propose a depression management system to increase access to treatment for depression.

Recently people are starting to pay attention to the vacant house. Vacant house across the country are expected to be a Million. Ministry of Land, Transport and Maritime Affairs has created a new legal provisions regarding maintenance to Vacant on the Construction Law. But Vacant house information systems in government are not available Other countries to clarify the role each entity to manage these Vacant and manages the Vacant. The national government has made the operating budget support program for the Vacant management. The local government has made legislation of self-government to create a DB for the Vacant management. A non-profit corporation is developing a program operated by the Vacant, and the Vacant intermediaries to consumers. Therefore, our country is also to expand the national budget for the Vacant administration, local governments should establish a comprehensive management system for managing and providing Vacant house research and DB.

The furniture industry has a high possibility to create value-added and a high potential to create new occupations due to the characteristics of the industry, which mainly consists of small and medium-sized enterprises (SMEs). However, the used furniture, which has sufficient reuse value, is also crushed and used as solid refuse fuel (SRF) recently. Besides, the number of waste treatment companies continues to decrease, and it occurs congestion of wood waste. As a way to solve the issue, a business model development of remanufacturing used furniture can be suggested as an alternative due to its high circular economic efficiency. Remanufacturing business including furniture industry creates positive effects in various aspects such as economic, environmental and job creation. In other words, remanufacturing is an effective recycling way to reduce input resources and energy in the production process. The results of economic analysis show that the expected annual revenue from the single worker furniture remanufacturing site was 104 million won which is 3.11 times more than the average income of a single-worker household in Korea and its B/C ratio was estimated about 30 which means high business feasibility. Revenue through furniture remanufacturing also showed 320 times higher than that of SRF production from the perspective of weight. In addition, it is shown that the GHGs reduction from the furniture remanufacturing is 2.2 ton CO₂-eq. per year, which is similar to the amount of GHGs absorption effect of 937 pine trees or 622 Korean oak trees annually. Thus the results of this study demonstrate that it is important to adopt an appropriate recycling method considering the economic and environmental effects at the end-of-life stage.

본 연구는 칼라 컴퓨터시각을 이용하여 가구에 이용되고 있는 활엽수 부재의 색에 의한 선별법을 제시하고자 수행되었다. 붉은 오우크 가구 부재를 대상으로 칼라 컴퓨터시각 시스템을 이용 화상을 얻은후 R,G,B 농도값을 근거로 나무결, 나무결함, 3가지의 색깔 즉 핑크색, 흰색, 갈색의 나무부분, 이밖에 배경에 대한 지식 베이스화를 행하여 각 부재에 대하여 이들의 비율을 quadratic Bayes classifier를 이용 구하였으며, 이 중 나무결, 나무결함, 배경을 제외한 3가지 색상에 대하여 부재가 갖는 상대적인 비율을 근거로 qadratic Bayes classifier와 neural network를 각각 이용하여 핑크색, 흰색, 갈색의 3가지 부재로 구분하였다. 선별의 정확도는 기존의 육안에 의한 선별을 기준으로 비교하였는데 qadratic Bayes classifier에 의한 선별이 91.7%, neural network을 이용한 선별이 96.7%의 높은 정확도를 보였다. 따라서 가구의 품질향상을 위한 색에 의한 부재 선별에 칼라 컴퓨터시각이 유용하게 이용될 수 있을 것으로 판단되었다.

This was a systemized bed consisted of storage units, a desk, a drawer, a sofa and a shelf. This bed system was not designed only for a certain age group of children but also for various age groups of children, since each parts of the bed can be sued separately. Separation of parts of the bed allowed children to decorate their own living space and gives them a chance to express their own feeling and thoughts by layout of parts. Design adopts the beauty of nature such as smoothly curve lines which are perfectly fit for the children's living space. The moving sofa located under the bed and the book shelf lead children to establish a pattern of reading habit. The draw and storage units offer nice space for keeping children's goods.

최근 스마트 수도미터의 보급을 통해 수용가구별 물 사용 자료를 수집할 수 있다. 이런 수용가구별 물 사용 패턴은 주말, 날씨 등 다양한 요인으로 인해 비선형적 특성을 가지고 있다. 그로인해 전통적인 시계열 예측 모형인 ARIMA 모형으로 적용하기 어렵다. 따라서 본 연구에서는 딥러닝 기반의 LSTM 모형을 통해 수용가구별 물 소비량 예측 모형을 개발하였다. 이 모형은 비선형적인 물 소비 패턴을 학습하기 위해 다양한 변수를 고려하였다. 서로 다른 종류의 4개 type (A : 단독주택, B: 아파트, C: 음식점, D : 초등학교)의 수용가구에 대한 ARIMA 모형과 LSTM 모형을 개발하였고, 학습에 사용되지 않은 새로운 데이터를 적용하여 정량적으로 예측성능을 비교했다. 그 결과, 모든 수용가구에서 LSTM 모형이 ARIMA 모형보다 성능이 우수하였다 (상관계수 : 평균89% | RMSE : 평균 5.60m³). 따라서 본 연구에서 제안한 모형은 수용가구별 물 사용량을 예측하는데 높은 활용도를 보일 것으로 기대된다.

In this paper, we proposed a new algorithm for determination of many-to-many corresponding pairs between block-polygon sets from the national topographical map and the cadastral map in Korea Land Information System, caused by different abstraction and generalization rules of the two maps. Our proposed algorithm starts from an assumption that a block-polygon for a N:M pair should significantly overlap at least one block polygon of the counterpart group, and determines N:M pairs using an iterative updating and searching with this overlapping analysis. This iteration process is terminated when the N:M corresponding pairs satisfy our predefined 1:1 corresponding condition.

The purpose of this study is to develop living room storage furniture with multiple functions and for analyzing living room system furniture that can correspond with lifestyles in the living room. Literature survey was used by collecting data on interior design books and magazines. System furniture is very functional depending on the purpose and spaces, and can be modified effectively with the development of design based on the resident's demand. Living room furniture was mostly arranged by two types. One was lower and slimmer in order to use the space effectively, the other totally occupied one side of the living room wall. Furniture combined with multiple functions of lights and electronics can increase the satisfaction and convenience of users. And furniture maximizes storage space and is systemized so that mixture and arrangement are diversified. Flexible and active way furniture that accept various electronic fixtures and performances in the living room. Furniture forms, materials, and colors will be designed for the functions and atmosphere of living rooms. This results will contribute to develop furniture that has additional features such as lighting and electronic appliances hereafter.

2022년 기준, 독거노인 가구 수 176만 가구 시대에 노인을 위한 케어 서비스가 필요하다. 고령화 사회에 맞춰, 노인 케어 서비스가 많이 출시되었으나 비대면 케어 서비스는 부족한 면이 있다. 비대면 케어 서비스의 경우, 특히 비싼 값에 판매된다는 단점과 로봇과 소통해야 한다는 단점이 있다. 이를 보완하여 저렴한 가격에 생명력을 지닌 식물을 이용해 소통을 증진시켜 우울감 해소를 돕는다면, 노인 비대면 케어 체계에 큰 도움을 줄 것이라고 확신한다. 이에 따라, 본 연구에서는 식물와 어플리케이션을 이용하여 저가격 보급화가 가능한 비대면 복지 시스템을 개발하고자 한다. 구체적으로, 화분이라는 대화 매개체를 통해 어르신들의 대화 증진을 유도하여 우울증 완화에 도움을 주고자 한다. 또한, 시스템을 통해 수집되는 일상 데이터를 활용해 이상징후를 파악하여 고독사 예방을 위한 후속 조치를 취할 수 있다. 본 논문에서는 위의 시스템을 통해 복지 사각지대를 해소하며, 어르신들의 정신 건강 증진에 기여할 수 있을거라 기대한다.
