When we look at the pattern techniques of wooden furniture in the 19th century Joeson Dynasty, we see that furniture patterns in the main living room were showy and colorful while furniture patterns in the library room, where noble men used to study, were natural and moderate, retaining the actual color of the material without any artificial coloring. Even the serial patterns in the Hwe-Jang technique, Which were used rarely, used moderate techniques. such as weaving in patterns with colorless woods - willow and black persimmon ets. - rather than using excessive techniques. However, considering the marquetry&intarsia technique of ceramic and the silver string intarsia technique of metal then current, wood work must also have been technically advanced. Korean modern wood furniture needs remedies to improve the standard of sound wood work techniques. This study shows that pattern unit production, composition techniques, and color effects etc. Using colored patterns bars, by improving the pattern composition techniques of Marquetry&Intarsia, can be substituted for the production logic of modern manufactured furniture.

Finishing materials and colors which were expressed in the space is an important factor to decide the imagination of the space. Therefore if we analyze and spotlight the space with that factors again, we will readily know the characteristics that are expressed in our living space. A purpose of this study is how the traditionality like national thoughts, customs and behavior patterns is changed, arranged and expressed in the korean housing space in the 21c on the finishing materials and colors. Though this study we can know that the traditionality which are expressed in modern housing spaces shows with accommodating to characteristic that is expressed in traditional housing spaces.

Imaging techniques using x-ray beam at high energies (>6KeV) such as contact radiography, projection microscopy, and tomography have been used to nondestructively discern internal structure of objects in material science, biology, and medicine. This paper introduces the x-ray micro-imaging method using 1B2 micro-probe line of PAL (Pohang Accelerator Laboratory). Cross-sectional information on low electron density materials can be obtained by probing a sample with coherent synchrotron x-ray beam in an in-line holography setup. Living organism such as plants, insects are practically transparent to high energy x-rays and create phase shift images of x-ray wave front. X-ray micro-images of micro-bubbles of $20\~120\;{\mu}m$ diameter in an opaque tube were recorded. Clear phase contrast images were obtained at Interfaces between bubbles and surrounding liquid due to different decrements of refractive index.

The purpose of this study was to identify factor structure of consumption value, clothing attitudes and the effects of consumption value on clothing attitudes. Questionnaires were administered to 513 college students living in Deagu and Kyungbook province. Data were analyzed by using frequency, factor analysis, multiple regression, t-test, ANOVA, and Scheffe-test. The findings are as follows. Consumption values were composed of five factors such as social value, differentiated individuality, material value, functional value, and circumstances value. Clothing attitudes were composed of five factors such as pursuit of individuality, fashion interests, utility pursuit, appearance conspicuousness, and social approval. The effects of consumption value on each of clothing attitude variables, pursuit of individuality, fashion interests, appearance conspicuousness, and social approval were explained by the factors such as social value, differentiated individuality, and functional value, utility pursuit by social value, functional value, and circumstances value.

Novel food materials can be produced based on biotechnology such as genetic recombination, microbial fermentation, and enzymatic engineering by utilizing living organisms such as animal, plant, and microorganism or by applying the enzymes isolated from them. Especially, exploration and development of novel prebiotics and probiotics attracted great attention worldwide in the food industry, of which the research and industrial trends in food biotechnology field are promoting the production of next generation sweeteners and proliferation of beneficial bacteria in gastrointestinal tract. Development and commercialization of novel food materials by domestic bioprocessing technology have been sluggish due to the GMO/LMO food safety issues. Meanwhile, the US and EU do not perceive badly about gene manipulation technology, and the research is most active in the fields of crops and GMMs, respectively. Genetic scissors, which are considered as next generation technology, are notable since foreign genes do not remain in final products.

Preserving intact genetic material and delivering it to the next generation are the most significant tasks of living organisms. The integrity of DNA sequences is under constant threat from endogenous and exogenous factors. The accumulation of damaged or incompletely-repaired DNA can cause serious problems in cells, including cell death or cancer development. Various DNA damage detection systems and repair mechanisms have evolved at the cellular level. Although the mechanisms of these responses have been extensively studied, the global RNA expression profiles associated with genomic instability are not well-known. To detect global gene expression changes under different DNA damage and hypoxic conditions, we performed RNA-seq after treating human cervical cancer cells with ionizing radiation (IR), hydroxyurea, mitomycin C (MMC), or 1% O₂ (hypoxia). Results showed that the expression of 184-1037 genes was altered by each stimulus. We found that the expression of 51 genes changed under IR, MMC, and hypoxia. These findings revealed damage-specific genes that varied differently according to each stimulus and common genes that are universally altered in genetic instability.

Present monetary system is based on fallacies. The purpose of this article is to highlight the pitfalls in economic thinking. The article shows that this way of thinking leads to the creation of inflation which is the root of all evil. The analysis proceeds in different approach to the contemporary theory of money. An inflation- free monetary system is introduced. Monetary system is the set of mechanisms that controls money. In this broad sense, monetary system can be divided into three different systems. Each of them has different goal; National monetary system which aims to raise sufficient funds in order to reach an optimal level of output growth that maintains full employment and satisfies the economic requirements of the community. National redistribution system which aims to redistribute funds in order to sustain individuals at or above a specified material standard of living, and enable government to provide public services. International monetary system which aims to preserve rights of parties in foreign exchange transactions.

Construction waste takes about 50% of total industrial waste. Researchers focuses to decrease the amount of construction waste by recycling the waste during the construction site. However, research about recycling the gelatin-sand composite is not yet been studied. This research is an experimental research on recycling the total specimen of gelatin-sand composite. Two methods were held when making the 2^nd generation of the gelatin-sand specimen. As a result, there was no difference in flexural strenght between two different method of 2^nd generation of specimen. However, the second method of 2^nd generation showed about 20% higher compressive strength than the first method.
