This study has conducted an experiment of comparing the flame resistant performance and combustion characteristics according to flame resistant treatment using the Cypress Luba and particle board that is commonly used for interior decoration and furniture. As a result of testing the flame resistant performance of Cypress Luba, the Cypress Luba injected with flame resistant resin using the vacuum pressure treatment has shown to have better performances (carbonized area 9.55% and carbonized length 22.91%) than the Cypress Luba treated with flame resistant coating having rubberized plastic components on its surface. For particle board, the specimen attached with fireproof film was identified to be better (carbonized area 40.10% and carbonized length 43.40%) than the specimen with non-fireproof film. For the results of combustion characteristics using the Cone Calorimeter, the specimen treated with flame resistant coating on the surface had faster ignition than the Cypress Luba injected with fire resistant resin using vacuum pressure treatment, and in the total release of calories, the Cypress Luba injected with fire resistant resin using vacuum pressure had $68.2MJ/m^2$, and the specimen treated with fire resistant coating on the surface had $111.52MJ/m^2$. For the particle board, the ignition time had a little difference but in the total release of calories, the specimen attached with fireproof film had $90.1MJ/m^2$ and the specimen with non-fireproof film had $107.6MJ/m^2$.

복식은 물질문화의 기본적인 요소로써 종교와 문화, 자연환경 및 민족 고유의 특징을 담고있다. 백러시아민족과 우크라이나민족은 러시아민족과 더불어 동슬라브민족에 속한다. 동슬라브민족은 따뜻한 흑해 연안에서 혹독한 기후의 북 러시아와 시베리아지방까지 널리 분포되어 살아왔다. (중략)

The purpose of this study is to investigate the characteristics of costume and its ornaments which are appeared in the traditional wedding ceremonial customs and the wedding costumes of Eastern Slav, that is consisted of Russian, Belarusian and Ukrainian from the 19 to the early of 20C. In this study, many different procedures of wedding ceremony with a various kind of wedding costumes are shown. A wedding custom of Eastern Slav had been developed by a intermixed style of the Christianism and a paganism. The wedding custom is organized by the 3 sequential procedures; before a wedding, a wedding, after a wedding Their wedding means the union of the bride into the bridegrooms family in order to establish a new family. Therefore, the wedding costumes have been developed according to this, and the head gears have developed as a symbol which presents the meaning. A brides costume is composed of a head gear, \"Lubaha\", and \"Sarafan\" or a skirt. A bridegrooms one is made up of \"Lubaha\", and trousers. These costumes are kept through their whole life, and are worn in every important ceremonial period. Even though, the wedding customs and the wedding costumes of Russia, Belarus, and Ukrain have been developed by their general commonness, there are regionally certain differences. It is one of the important research object of the Eurasian era in the view point of culture and ethnographic, that to know the symbolism appeared in the traditional weeding ceremonial customs and the wedding costumes of Eastern Slav.ding costumes of Eastern Slav.

Toxic gases from five types of interior building materials were investigated according to Naval Engineering Standard (NES) 713. The materials were plywood, indoor wall coverings (wood wall plate members and pine wood), reinforced Styrofoam insulation, laminate flooring, and PVC. Specimens were measured using an NES 713 toxicity test apparatus to analyze the hazardous substances in combustion gas from the materials. We used the US Department of Defense standard (MIL-DTL, Military Standard) to calculate the toxicity index of the combustion gas. Emissions of $CO_2$ from all specimens did not exceed the NES 713 limit of 100,000 ppm. The amount of CO gas emissions from reinforced Styrofoam insulation was 6,098 ppm. 25 ppm and 49 ppm of formaldehyde were released from the reinforced Styrofoam insulation and PVC flooring, respectively. These values were less than the limit of 400 ppm. The highest emissions were from $NO_X$ emitted by plywood and were above the limit of 250 ppm. The toxicity index of the specimens were calculated as 5.19 for plywood, 4.13 for PVC flooring, 2.35 for reinforced Styrofoam insulation, 2.34 for laminate flooring, and 1.22 for indoor wall coverings (pine wood). Our research helps us to understand the properties of these five interior materials by analyzing the combustion gas and explaining the toxicity of constituents and the toxicity index. Also, it would be useful for giving fundamentals to guide the safe use of interior materials for applications.
