In recent years, Korean government has focused on improving the environmental impact of products in order to reduce greenhouse gas emissions and to achieve their energy goals. The government has been conducting the following polices such as green procurement inducement and certification system. After carbon labeling was conducted in 2009, among a total of 1,065 items, 97 building materials have been given a certification: finishing materials items have the highest weight (56%). The increase in the certification numbers shows that there has been considerable technical efforts in the building material industry. At the awareness of carbon label and purchase of low carbon product, however, customers are aware of carbon labeling but the purchasing rate of carbon product is low. In this paper, we suggest that low carbon activities must also be considered in order to create client value by adding the concept of ecological efficiency. The objective of this study to measurer the eco-efficiency of carbon labeled building materials on the basis of environmental aspects of the product with the perspective of economy for purchasing the excellent products.

The concepts of interior design work have set forward an aesthetic and functional proposition to be answered by those who design spaces. The available range of suitable materials for interior use appears to be almost inexhaustible in this day and age. Now a day, relatively new fields of study on environmental-friendly interior examine humans'innate affinity for health and explore its implications for architecture and the built environment. A growing field of research suggests that spaces' relationship to aesthetics and environment can either help or hinder their occupants' health and wellness, productivity, and even their creativity. This paper presents several examples of already built apartment houses in practice, and discusses the demand of users of the spaces for health and sustainable environment, deepening the relationship between newly-constructed spaces and the remodeled ones. The considerations to some new and contemporary materials from the aspect of healthy indoor architecture design are presented in this paper. Designers need to rethink the conventional and high-tech interior environment in apartment houses with respect to perceived air quality, material emissions, and odors. The future of interior design is oriented on light shapeable materials which are able to create a unique memorable atmosphere. The primary assignment in accepting recent materials and proceedings is our responsibility to creating proposals, that are mainly safe, hygienic and environmentally proper.

1. In the past, the smoke-pipe type dry kiln being characterized by the low cost of installation and easy operation was only used by the small scale of wood processing enterprisers for drying softwood and finishing air-dried stocks that were belonged to easy drying properties. The smoke-pipe type dry kiln usually was not suitable for drying hardwoods and green woods because of the difficulties of controlling drying conditions. 2. However, the smoke-pipe type dry kiln heated with smokeless coal which was designed and constructed by the authers was demonstrated to maintain higher accuracy of controlling temperature and humidity than the other smillar types of kiln. Also, since it was constructed with home made equipments, it is supposed to offer the opportunity to install the kiln by the small scale of wood processing enterprisers who could not install the dry kiln because of economical and technical difficulties. Thus, it is expected that promoting the spread of installing the dry kiln will realize the rational use of wood.

New series of phthaloperinone dyes were synthesized by the condensation reaction between tetrachloro-phthalic anhydride, 2,3-naphthalene dicarboxylic anhydride and o-phenylenediamine, 1,8-diaminonaphthalene, 1,2-diaminoanthraquinone. These dyes absorb at around 370-490nm. It was found that introduction of naphthalene and anthraquinone moiety on the perinone system produces a large bathochromic shift of 100nm. The synthesized dye 7 containing anthraquinone moiety in perinone chromophoric system exhibited superior heat stability and bright color as yellow chromophore. New dye 7 have been investigated in terms of interacting with volatile organic compound(VOC) $EtNH_2$. The sensing behaviour of the dye 7 toward $EtNH_2$ was studied by UV-vis absorption spectroscopy. Sensing mechanism of dye 7 to $EtNH_2$ was supported by theoretical calculations based on DFT method.

Molecules always show broad absorption band envelopes, and this results from the vibrational properties of bonds. The width of an absorption band can have an important influence on the color of a dye. A narrow band imparts a bright, spectrally pure color to the dye, whereas a broad band can give the same hue, but with a much duller appearance. Typically, half-band widths of cyanine dyes are about 25nm compared to value of over 50nm for typical merocyanine dyes. Thus, cyanine dyes are exceptionally bright. The factors influencing the width of an absorption band can be understood with reference to the Morse curves. The width of the absorption band depends on how closely the bond order of the molecules in the first excited state resembles that in the ground state. We have quantitatively evaluated the "molecular structure-absorption band shape" relationship of dye molecules by means of Pariser-Parr-Pople Molecular Orbital Method(PPP-MO).

The purpose of this study is to evaluate environment-friendly planning feature in Environment-friendly Certificated apartments and to use the basic planning data of housing. Seven Environment-friendly Certificated apartments have been analyzed. The findings of this study are as follows: Environment-friendly planning features are categorized into 4 items; floor planning feature, material planning feature, universal planning feature and environmental planning feature. Among floor planning features, natural sunlight, built-in closets, and differentiated floor plans are well considered, but the flexible floor plan for resident's lifestyle and green space are lack. Among material planning features, environment-friendly finishing materials, environment-friendly products and energy-efficient double-pane windows are well considered, but implementation for resource savings using recycled materials are lack. Among universal design planning features, removal of threshold and installation of safety device in bathroom are not well considered. Among environmental planning features, usage of alternative energy like solar energy are not applied. The environment-friendly planning features in interior space should be introduced in diverse ways.

Traditionally dyeing fabric with dyestuff extracted from Indigo was a popular method of obtaining blue color in the world before synthetic dyestuff was developed in the 1890's. As the Korean traditional process of dyeing extracted from Indigo, there are two kinds of dyeing process; The deposite dyeing of muddy Indigo and the leaf dyeing of Indigo plant. In order to study the properties of leaf dyeing of Indigo, the dyeing properties, color difference on cotton and silk fabrics under several dyeing conditions were investigated. In the dyeing of cotton and silk fabrics with leaf dyeing of Indigo, the dyeing affinity of silk was higher than that of cotton, the cotton and silk fabrics were dyed dark yellowish Green and dark Blue, respectively. the dye uptake increased with the increase of dyeing temperature and of the unmber of dyeing times. When cotton and silk fabrics dyed with leaf dyeing of Indigo at 6$0^{\circ}C$ for six number of times, the K/S value of dyed cotton and silk were calculated 1.286, 2.613 respectively.

In this report, nano-sized catalysts were introduced onto fabric surface to eliminate toxic chemicals assisted by physical adsorption. For chemical removal of toxic compounds, a series of zirconium-containing catalysts were synthesized and treated on fabric to catalyze the hydrolysis and oxidation of target molecules. Antimicrobial was also introduced for the research purpose to prove the compatibility of as-synthesized catalysts with other solutions. Zirconium ligated with hydroxyl group and MOF(Metal-Organic Frameworks) were exploited as catalyst for removal of toxic compounds, while zinc complex was used for an antimicrobial to culminate in a chemical shield. Once fabrics were functionalized, fabrics were washed 2 or 5 times for a washing durability test. The amount of catalyst in textile were measured by ICP-MS and weight increasing ratio of fabrics.

Under the paradigm of 'Eco', the core of sustainability management, this study aims to establish both domestic and international markets and secure competitiveness in the global markets through the development of children's furniture composed of recycled and unharmful materials. Currently, in Europe and in the Western regions, the concepts of 'eco-friendly', 'children', and 'DIY' are well-placed in the daily lives of the people. On the other hand, compared to the domestic demand for eco-friendly children's furniture, the essential approach and the qualitative improvements about the subject are being slowly progressed. Particularly, the process of applying eco-friendly materials and finishing materials to the children's furnitures are mostly in a non-existent state. Thus, in this study, simple application of basic eco-friendly materials such as natural woods or imitation of overseas furniture designs were avoided to create transformable eco-friendly one-touch DIY children's furniture for children's growth and development through the application of eco-friendly processes of technology, design, and other stages of the development process. In other words, under the big category of eco-friendly children's furniture, the furniture was developed through an environmentally-friendly process of universal design that is suitable for children of all ages, and thus, ultimately maximizing the economical effective value and reducing consumption of resources and environmental pollutions.

Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Apartment residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling construction has a unique characteristic in that the residents are already determined prior to construction execution. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.
