The small dining tables which are made of bamboo were deteriorated condition when those were excavated from Mado shipwreck No.1. Therefore, preliminary test was conducted for consolidation (Sucrose, Dammar gum, Cetyl alcohol and Polyethylene glycol 4000) then impregnated and vacuum freeze dried. After the test, since the treatment with vacuum freeze drying using an aqueous solution of PEG 4000 keep the shape well the most and present bright colour, waterlogged archaeological bamboo conserved with vacuum freeze drying using an aqueous solution of PEG 4000. One bamboo table consolidated with soluble PEG 4000 from 10% to 40%, then vacuum freeze dried. Another impregnated with soluble PEG 4000 from 10% to 70%. After that, it was separated and held in polycarbonate sheet for preventing bending during dry. The small dining tables are the three dimensional shapes and have some loss. Therefore the mounting for support tables were necessary which are made of acrylic sheet. It keep the table shape and make it convenient for storage and handling.

The purpose of this study was to investigate the experimental design by using deconstructive design and mobile design depicted on Hussein Chalayan' works. Hussein Chalayan, the Turkish-Cypriot who is based in London, says' Challenging is the best word for me'. And so word, 'radical' that has difficult connotations was chosen for this study It implies two menainigs for the word. The first thing is "extreme" - something that is drastic. And 'Applied to clothes', it can probably mean "experimental". He has iconoclastic ideas and his ramp shows are always high on concept, experimentation of art and utility. His approach to fashion derives from philosophical and intellectual theories of deconstruction and mobility, which he expresses through his designs. Deconstructionism, in fashion, rejects customary rules and breaks all conventions. It questions aesthetic norms about bodily proportions and the criteria of beauty, emphasizes the adding on, or discovery of, an irrational moment, and reveals the processes of tailoring in clothing. The shape and the construction of the garment is more important than the color. Cuts. tears, asymmetries, matching different materials are among the most evident features of the deconstructive design. And Chalayan performed the mobile design of transforming furniture into clothes. Chair covers became dresses. a coffee table became a skirt which were designed by Chalayan, with geometric and architectural references. Chalayan says he was inspired by the idea of refugees fleeing. Besides Chalayan uses clothing as an art to reinterpret and reform the human body in a continuous tour de force of body/identity conceptualism and dressmaking. He reflect the body's function in the cultural context of architecture, science, or nature - and then attempt to translate his findings into clothing.dings into clothing.

The Iksan Mireuksaji stone pagoda, designated as national treasure No. 11 in Korea, has been in the process of disassembling for reconstruction as part of the cultural heritage conservation program. The pagoda is mainly consisting of granite, which is relatively resistant to weathering. However, it has lost its original rock color due to various contaminants deposited at the surface since it exposed to the atmospheric environment long time. In this research, we categorized the secondary inorganic contaminants into the genetic type, and also quantitatively examined occurrences and types of pollutants in the oxidation area of the pagoda surface in which the area is clearly distinguished by naked eyes. Geochemical behavior of soluble pollutants through reaction experiments are demonstrated, and effective methods of cleaning for the conservation and scientific applicability of the surface cleaner are also studied.

1) The general composition, vitamin, amino acid, digestibility and nutrition efficiency of the seeds of Pinus Koraiensis Sieb. et Zucc. were examined. (2) Pine tree seed contains approximately 17% or more protein nearly pure one. The amino acid composition of the protein was analyzed. When compared with the values of soybean and peanut reported in the literature, it contains slightly mare histidine and glycine etc., showing that the seeds are of high nutritional value. (3) The protein digestibility was 87% and the total content of digestible protein was approximately 14.9%, T.D.N. was 159.4%, proving itself excellent. (4) As to vitamins, it was found out that the seeds contain 275 r of $B_1$ and 99 r. As to minerals, Ca (301.2 mg) P (361 mg) and K (272 mg) were found to be contained in the seeds (5) The basic diet was considered nearly perfect from the view-point of nutrition, and to this were added 30%, 5% and 10% of the test sample respectively and were fed to albino rats. Among the three treatment, the 3% sample adding proved to be the mast effective one, showing the most efficient growth. Thus it can be presumed that the pine tree seeds certainly contain U.G.F. (6) The anatomical examination of the intestines of albino rats showed that the feeding of pine tree seeds bad favorable effect on the development of heart, kidney and pancreas.

Recently, it is the well-known that there are some kinds of problem the waste concrete generated while repairing, reinforcing and dismantling of structures in the domestic and overseas. In this paper, various tests were performed about the use of the recycled concrete fine aggregate for the materials of high quality and structural concrete. And also, in order to improve structural performance of the concrete structure the steel frame was under overcrowded arrangement of steel bar. Consequently, it was be necessary the Self-Consolidating Concrete(SCC) that can fill the concrete into the work-form corner which has become overcrowded arrangement of steel bar without any other vibration. The purpose of this study is related to the properties of Self-Consolidating Concrete(SCC) according to mixing ratio of recycled concrete fine aggregate.

The seismic behavior of the lightly reinforced concrete frames (LRCFs) was controlled by the nonductile behavior of the critical regions. These critical regions require retrofit to improve the seismic behavior of the lightly reinforced concrete frames. Critical column end regions must be retrofit to increase the global ductility capacity. The objective of this research is to evaluate structural strengthening performance of lightly reinforced concrete frame with Strain hardening cement composite(SHCC) experimentally. The experimental investigation consisted of a cyclic load tests on 1/3-scale models of precast infill walls. Reinforcement detail of infill wall was variables in the experiment. The experimental results, as expected, show that the multiple crack pattern, strength, ductility and energy dissipation capacity are superior for specimen with SHCC infill wall due to bridging of fibers and stress redistribution in cement matrix.

A robust, accurate, broad-band, alternating current sensor using fiber-optics is being developed as a part of optical over current protection relay system. The sensor uses the Faraday effect in optical fiber and polarimetric measurements tc sense electrical current. The current sensing coil consists of a length of twisted optical fiber and Faraday rotator mirror to suppress the linear birefringence effect. Due to its single-ended closed path structure, it can not only be easily installed to the target with great isolation from other fields in the vicinity, but the sensitivity can be increased by using multiple turns. This paper reports on the theoretical backgrounds of the sensor design and the preliminary experimental results.

To evaluate the applicability of the construction method involving infilling CFT columns by pumping-up, a trial construction was done using 6 actual size test samples. The 12.8m-high test samples were similar to a four-story building scale. The pumping-up level was controlled at 12m. The test used two types of high performance concrete with $450kgf/cm^2$ standard design strength, and a concrete pump which is used domestically. The pressure changes in pipes or pump as well as the changes in concrete characteristics were measured during construction. in order to evaluate applicability. After the concrete hardened, the column was dismantled. The filled state of the concrete, concrete strength distribution according to column height, etc., were checked to evaluate the quality of the concrete, From the results, some basic data which characterize the pumping-up pressure were suggested. Also, the strength of hardened concrete as well as the filled state were proven to be acceptable ranges.
