Today, modern people are exposed to various environmental pollutants such as harmful substances and stress, which can compromise health. Therefore, a healing culture that seeks to enjoy human life based on the healing of body and mind is attracting great attention. The purpose of this study is to develop environmentally friendly natural dyeing considering a healing concept with four elements: color, dye, material, and pattern. The research methods and scope are based on a theoretical review of healing and research on the literature of bedding related to natural dyes, national and international books, the Internet, etc., and naturally dyed bedding. This paper presents actual production research. The results of this study are as follows. First, the elements of color, dyeing, material and pattern were developed through the process of a bedding design development model that applies a healing concept and can be commercialized as a healing bedding product. Second, a healing color proposal was expressed in an intermediate color system of pink, ocher, lavender, and indigo colors for emotional stability, warmth, calmness, comfort and softness. Third, eco-friendly bedding using natural dyes with medicinal efficacy can obtain the healing effect of the natural treatment method, which can aid healthy sleep. Fourth, the pattern used in the bedclothes was a motif of Sarasa embroidery, flower embroidery, ribbon embroidery, and wave quilting motifs to provide psychological stability as a healing concept in the sleeping environment. The natural healing bedding with the healing concept proposed in this study has natural treatment that is beneficial to human health and the development of bedding with natural dyes will lead to an increase of demand for the sleeping environment.

Recently, environment-friendly cultivation technology is popular. A cultivator is useful for turning over the stall bedding in a poultry farm. In this study, a rotary-based cultivator with a rechargeable battery was developed for eco-friendly management of broiler chickens. From the results of the test run, the clustered stall bedding was approximately divided into up and down layers. Through experimental evaluation, the working width was more than 60 cm, and the noise was less than 80 dB. The output of the motor was 400 W, and the speed of rotation was 3000 rpm. Electric battery type cultivators are expected to be widely used in the livestock industry.

Polyester is mainly used as a bedding filler material. PLA fiber as an eco-friendly material for substituting polyester has a low melting temperature and therefore a hardening process is impossible. This study is to develop the oil for feather touch that can treat at the melting temperature of PLA. The slippery and soft aminosilicone emulsion, and the bulky epoxysilicone emulsion were used. They had proper viscosity and particle size for flexibility and elasticity. When using methoxy aminosilane [$H_2NSi(OCH_3)_3$] as an aminosilane and [$Zn(OCOCH_3)_2$] as a catalyst, the hardening reaction was fast and effective. Feather touch process were treated by 2 steps. At first step, aminosilicone emulsion, epoxysilicone emulsion and methylaminosilane were mixed and homogenized, and at second step, 5% blened solution of the first step, Zn catalyst 1%, distilled water 94% were treated at PLA fiber. After treatment the static friction coefficient and dynamic friction coefficient were reduced to 23.5-60.8% and 30.0-61.3% respectively, and the laundry and sun light fastnesses have not shown any decrease.

After Kyoto Protocol was adopted for green gas reduction, each nations are stepping up efforts to reduce $CO_2$ of a typical green gas. Construction industry also is trying $CO_2$ reduction with the techniques of two types which are software and hardware techniques. The software technique are Passive Design considered green gas emission and the environment impact assessment by LCA. The hardware techniques are adjustment of equipment system and development of eco- friendly material. But, it is nonexistent that a study related to $CO_2$ emission considered detail process in construction industry. This study analyzed the relativeness of equipment combination and $CO_2$ emission by calculate $CO_2$ emission follow to equipment combination on earth-work which is the process emitted most $CO_2$ among railway bedding construction.

In this study, textile designs were developed by applying Norigae for motives, were digital-printed for it's eco-friendly, delicate and short printing time and as final products, necktie, bag and bedding was developed with them. The purposes of this study were to develop a unique textile design, and then to enhance the competitiveness of Korean textile industry in the world market and pass down a Korean traditional fiber art cultural legacy. The results are as follows Norigaes are a sort of Korean traditional ornaments worn on women's Korean traditional costume. These can vary in color, material, shape, composition and said to have very high artistic value from the standpoint of the modern view. And these are symbols of happiness and women's longing of Korean traditional society. So Norigaes are worthy of applying Korean traditional motive for modern textile design. The textile designs applied a Norigae in this study were estimated comparatively high.

This study analyzes the conditions and products of internet shopping malls that sell natural dyeing products. In this study, 98 natural dyeing internet shopping malls were selected. The results of this study are as follows. The locations of the internet shopping malls were Gyeonggi-do, Seoul, Jeollanam-do, Gyeongsangbuk-do, Gwang-ju (city), Daegu (city), Busan (city), Gyeongsangnam-do, and Jeju-do. The most frequent dyes of the natural dyeing products were loess, followed by charcoal, indigo, and persimmon. Indigo was most frequently used in Seoul, with loess and charcoal most frequent in Gyeonggi-do. Persimmon, indigo, loess, and charcoal were mainly used in Jeollanam-do, with persimmon and loess in the Gyeongsangbuk-do, and persimmon in Jeju-do. The highest ordered product categories were accessories, followed by adult clothing, interior decoration products, and bedding. The most frequent products were bedclothes, followed by scarves, female shirts, blouses, pillows, female jackets, and vests. Regarding the price of products, 150,000-200,000 won was the highest for the Saenghwal Hanbok, with 10,000-30,000 won for underwear, 30,000-60,000 won for accessories, and 100,000-150,000 won for bedding. Concerning product information, 58.2% of internet shopping malls offer the product size and almost half of them did not show the properties or directions for handling the product. Based on the research results, the problems of the conditions and products of natural dyeing internet shopping mall were derived. The results show that the natural dyes of internet shopping malls lacked regional symbolism, the products were not specialized, and product information was not fully offered to consumers. To solve these problems, the strategies for marketing the promotion of the natural dyeing internet shopping mall were, ‘Using natural dyes from local resources’, ‘Market oriented and specialized item design’, and ‘Offer right product information’.

1997년 온실가스 감축을 위한 교토의정서가 채택된 이후 각 국가들은 대표적인 온실가스인 이산화탄소를 줄이기 위하여 전 산업에 걸쳐 다각적인 노력을 하고 있다. 건설산업에서도 온실가스 배출량을 고려한 Passive Design 이나, LCA기준에 의한 환경영향평가와 같은 소프트웨어적 기술의 개발 그리고 설비시스템의 조정이나 친환경 자재의 개발과 같은 하드웨어적 기술의 개발과 같이 두 가지 형태의 기술이 다양한 방법으로 개발됨으로써 이산화탄소 저감을 시도하고 있다. 그러나 건설산업에서 세부공정을 고려한 이산화탄소 배출과 관련한 연구는 전무하다. 본 연구에서는 철도노반공사 중에서 이산화탄소 배출량이 가장 많은 공정인 토공사를 대상으로 장비조합에 따른 이산화탄소 배출량을 산출하여 장비조합과 이산화탄소 배출량 그리고 공사기간의 상관성을 분석하였다.
