Various types of functional bedding for inducing and maintaining sleep, are developed and launched with the importance of improving health through sleep emphasized currently. The purpose of this study is to examine development status and direction of functional bedding in the $4^{th}$ Industrial Revolution era, through systematic classification of elements of IoT-based smart bedding cases actively developed as functional bedding at home and abroad. Through previous research, literature and Internet data, characteristics and functional extension of smart bedding and the background of smart bed development was analyzed. And it was analyzed that smart bedding pursues recent functionalism and convergence of physical and digital concept such as IoT or AI, and also mental value to improve sleep quality. As bedroom where smart bedding place in has the private and limited characteristics and users are in sleep-conscious, that hard to ensure power and discomfort in carrying are moderated and the aesthetic elements are not very important, and that the smart bedding performance while sleeping were affected on developmental background. Based on CES case study and analysis on how smart beds are functionally expanded from conventional bedding, smart beds have gained information through digital sensing, and common properties that can be controlled anytime, anywhere, using a smart phone. Some set up the right environment and pose, while others stimulate nerves directly as active intervention. It is expected that smart bedding will be developed to cure user's body and mind, through active intervention when sleeping.

The purposes of this study were to investigate actual use, design preference, and purchasing behaviors of bedding among married women in their 30s to 60s, and to determine the differences by age groups on these variables. The subjects were 623 married women and the research method was survey. The data were analyzed by descriptive statistics, cross tab analysis, multiple response analysis, ANOVA, and Duncan's multiple range test, using SPSS program. The results were as follows. First, on the actual use of bedding, the possession quantity of the bed cover and mattress was 2~4 while bedclothes and pillow was 7~8. The period of use of bedding was about 2~4 years and the frequency of washing was about 2~3 times a month. Second, married women generally preferred white and pastel tones, floral patterns, cotton fabrics, and a clean and comfortable image on bedding designs. Third, on the purchasing behaviors of bedding, married women considered functional damage and health & sanitary aspects as important purchase purposes. The most important selection criterion was fabric. Price, tactility, functionality, and manageability were also important criteria. Married women generally used the internet and store displays as important information sources, and considered bedding specialty stores as important purchase places. They generally spent about 200,000~300,000 won a year to purchase bedding. Fourth, the actual use, design preference, and purchasing behaviors of bedding showed many differences by age group. Therefore, it is needed to establish product development and marketing strategy of bedding, considering customers'age variable.

There are many kinds of elements and processes for the development of high quality bedding products like fiber, high-temperature heat treatment, dyeing process, tenter drying with softening agent and multiple final finishing. Especially we examined the mechanical characteristic properties of fabrics according to different yarn types. The critical physical properties of the yarn consisting the pile knitted fabrics were obtained for the development of the hi-grade bedding items. The material property and the exhaustion behaviour of the developed pile knitted fabrics composing of different yarns were measured and observed. The physical properties of the developed fabric were evaluated through the material property analysis of the yarn, the physical nature of the pile knitted fabrics and the data of the exhaustion performance; tensile strength, tensile elongation, tearing strength, cross section of yarn types, dyeing properties etc. And then high-class of bedding items were knitted using the double raschel machine to make the pile knitted fabrics.

육묘장의 두상관수장치는 균일하게 관수되어야 모종도 균일하게 성장한다. 본 연구에서는 부채꼴 분사노즐을 이용한 두상관수장치의 노즐 설치위치에 따른 관수상태를 조사하여 균일관수방법을 구명하였다. 살수량은 주행속도에 반비례하였고, 관수균일도는 노즐과 관수면과의 거리에 큰 영향을 받으며 주행속도의 영향은 없었다. 단일노즐에 의한 두상관수인 경우 노즐 끝에서 관수면이 60cm 이상 멀어질수록 관수균일도가 향상되며, 연속노즐에 의한 두상관수인 경우 관수면이 노즐분사 각도의 2차 교차점에 위치할 때 관수균일도가 가장 좋은 것으로 나타났다. 두상관수장치의 균일관수를 위해서는 작물의 머리높이가 분사노즐의 2차교차점에 일치하도록 노즐의 위치를 정해야 하며 작물의 자람에 따른 노즐대 놀이를 조절해 주는 것이 바람직한 것으로 판단된다.

After COVID-19, the number of people with sleep disorders around the world is increasing. In particular, in the flow of the 4th industrial revolution, the differentiation of types and characteristics of the sleep industry is accelerating. Therefore, in this study, the characteristics of each type of sleep-related industry were reclassified from an industrial point of view, and based on this, an attempt was made to review the classification system that can help companies develop sleep products and improve related national systems. Based on the 10th standard industry classification, we compared input cost, value, and usability and analyzed common characteristics, treatments, and preventive effects based on this. A comprehensive taxonomy using matrix analysis was reviewed. As a result, in terms of cost (A), the most common sleeping products are general mattresses and general bedding. It is an IOT device (auxiliary device), and the value aspect (B, B/D) included sleep cafe, bedding rental and management service, and sleep consulting. In terms of utility (A/B), a total of 6 product groups including sleep aids (health functional foods) belong to this category, and in terms of treatment (A/C), a total of 3 product groups including sleep clinics (medical services) belong to this category. As for the product group (A/D) with both properties, it was found that non-insurance sleep treatment medical devices, sleep-related over-the-counter drugs, and some sleep monitoring applications belong to this category. Ultimately, it was found that the sleep industry classification enables the most active product development and composition according to the relative relationship between cost and utility, and treatment and utility. appeared to be necessary.

This project purpose to develop a "custom patient gown" can satisfy with functional and aesthetic aspects for improving the problems of the existing children's patient gown that no unified image and discomfort in cooperation with the Public Design Development office as part of the citizen-friendly design improvement projects which one of the public politicizes of Seoul. The following are the results of design process for children's patient gown applying the universal design. First, the children's patient gown of the shape were classified into patient gown, rehabilitative gown and special gown and based on human-centered design to pursue the custom patient gown. Second, the color used pastel shades part of the Seoul colors and focused on emotions with color therapy theory. It was emphasized the aesthetic aspect by arranged the colors which harmonized with the main colors, also classified the wards and sizes. Third, for the functional materials of patient gowns was used the washable fabric and tender processing. Fourth, the accessories were matched the unified image and colors are suitable for the hospital environment such as bibs, aprons, and bedding. Fifth, Haechi, the symbol of Seoul was used as the logo. The Haechi logo and emotional message were applied to patient gowns to enhance the communication efficiency between patients and their guardians. As described above, the custom patient gowns for children's hospital will have significant ripple effects when they are expanded to national, public and private children's hospital. Such a qualitative change will pursue the respect and value of human by expanding the areas of public design for adults, the weak and the old-age society in future.

최근 난방장치에 대한 에너지의 효율적 사용측면에서 경제성과 안정성을 높이기위한 지속적인 연구 개발이 이루어지고 있다. 특히 고성능 및 신기능 소재에 대한 기술개발이 활발히 이루어지고 있다. 본 논문은 에너지 전달특성이 우수한 발열제품 개발에 관한 것으로 침구류나 매트리스 등에 사용되는 발열체는 전열선을 사용하는 것으로서 전열선이 가늘기 때문에 열의 분포가 전열선 주변에서만 집중되어 전열선에서 떨어진 부분과 온도 편차가 심하게 발생되는 단점이 있다. 또한 전자기가 유도되어 인체에 유해하고 에너지 소비도 많다. 따라서 원적외선, 음이온 등이 방사되어 인체에 이로우면서도 무해할 뿐 아니라 열전도가 우수하여 에너지 효율을 높일 수 있는 SiC계 세라믹을 이용한 면상발열판넬을 개발하고자 한다.
