The purpose of this study was to identify the design concepts embedded in our traditional interior space. The majority of this research was achieved through literature review as well as examining traditional Korean houses. The major findings were summarized as follows : First, traditional Korean interior space is contemplative. This is created possible by the careful placement of indispensable furnitures and accessaries resulting in an abundance of unoccupied space. Therefore, the room assumes a peaceful atmosphere which calms the mind and creates a tranquil setting. To enjoy the placidity of Korean interior space a humble demeanor and contemplative thought are required. Next, traditional Korean interior space is modest. This is created by the moderate proportions that do not challenge human scale. Traditional Korean interior space does not dominate its surroundings but rather conforms with them. This contrasts with traditional western houses which utilizes an overbearing scale sacrificing intimate space. Thirdly, traditional Korean interior space is raw. In other words, the materials used in house retain their self-evident natural state and are not artifically manipulated to hide their inherent properties. The fundamental conceptual belief that interior space should not defy nature but instead become part of it. Lastly, traditional Korean interior space is not decorative Rooms are not congested with frivolous aesthetics. Although this does not immediately attract the people's attention, eventually the interior space establishes a unique line of communication with them.

The purpose of this study is to understand the present status of life style and housing demands of residents in Yoing-in and Kwang-Ju in Kyung-Ki province, Korea. Field study methods were carried out practically using participant observation method and open-ended interview method, and the data were gotten by sketch, recording, photograph and memo. As a result, the followings were proposed. First, it was necessary to hide or reduce of the neighborhood's noise or direct view because those people thought the invasion of the privacy problem was very severe. The master planning of the complex method could be an alternative plan for this kind of problems. Second, it was needed to be the planning that could follow up the out-door friendly situations. To achieve this, the in between living space are needed that connected the outside and inside of the house. Third, the planning of the housing space should flexible for each participant's needs of the future. To achieve this, each unit in the suburban housing complexes should be fixed to the each character of the people's various needs.

This work provides new forensic techinque to a hide message on a directory index in Windows NTFS file system. Behavior characteristics of B-tree, which is apoted to manage an index entry, is utilized for hiding message in slack space of an index record. For hidden message not to be exposured, we use a disguised file in order not to be left in a file name attribute of a MFT entry. To understand of key idea of the proposed technique, we describe B-tree indexing method and the proposed of this work. We show the proposed technique is practical for anti-forensic usage with a real message hiding case using a developed software tool.

Animal glue has been used as a binder in Dancheong since the Joseon dynasty. Binders play an important role in determining the physical characteristics of a painting layer. The analysis of binders can be used to identify the materials and techniques used in traditional Dancheong. Binders can be investigated using physicochemical component analyses methods such as gas chromatography/mass spectrometry, pyrolysis-gas chromatography/mass spectrometry, and fourier transform infrared spectroscopy, but the detection characteristics vary depending on the degradation properties of the pigment and binder. Therefore, cross-validation using a combination of physicochemical analysis and enzyme immunoassay is used to increase the reliability of the results. In this study, we present an enzyme-linked immunosorbent assay (ELISA) as an example of an enzyme immunoassay as a method for analyzing animal glue, a traditional binder used in Korea. The applicability of ELISA was tested using commercial animal glue, in addition to animal glue produced using a variety of extraction conditions. The animal glue was analyzed in a Noerok-additionally coated-replica sample to evaluate the possibility of analyzing the animal glue in a paint layer mixed with pigment. Based on the results, we performed an assay on the use of animal glue in the Dancheong sample of the temples of the Joseon dynasty, that are estimated to have been built in the 17^th century.

Encryption technology is to hide information in a cyberspace built using a computer and to prevent third parties from changing it. If a malicious user accesses unauthorized device or application services on the Internet of objects, it may be exposed to various security threats such as data leakage, denial of service, and privacy violation. One way to deal with these security threats is to encrypt and deliver the data generated by a user. Encrypting data must be referred to a technique of changing data using a complicated algorithm so that no one else knows the content except for those with special knowledge. As computers process computations that can be done at a very high speed, current cryptographic techniques are vulnerable to future computer performance improvements. We designed and implemented a new encryption program that combines ancient and modern cryptography so that the user never knows about data management, and transmission. The significance of this paper is that it is the safest method to combine various kinds of encryption methods to secure the weaknesses of the used cryptographic algorithms.

In this paper, we introduce a new LUT based watermarking method for a halftone image. Watermark bits are hidden at pseudo-random locations of halftone image in the proposed method. The pixel values of the halftone image are determined from the LUT entry indexed by both the neighborhood halftone pixels and current grayscale value. The LUT is trained by a set of grayscale images and corresponding halftone images. Advantage of the LUT method is that it can be executed very fast compared with other watermarking methods for a halftone image. Therefore, the algorithm can be embedded in a printer. Experiments for real scanned images showed that the method is a feasible method to hide the large amount of data within a halftone image without noticeable distortion and comparing to the DHED method, is almost same in quality but significantly shorten in processing time.

Purpose: This research aims to investigate the impact of corporate integrity on stock price crash risk. Research design, data, and methodology: Taking 1419 firms listed in Shenzhen Stock Exchange in China as a sample, this paper empirically analyzed the relationship between corporate integrity and stock price crash risk. The main integrity data was hand-collected from Shenzhen Stock Exchange Website. Other financial data was collected from CSMAR Database. Results: Findings show that corporate integrity can significantly decrease stock price crash risk. After changing the selection of samples, model estimation methods and the proxy variable of stock price crash risk, the conclusion is still valid. Further research shows that the relationship between corporate integrity and stock price crash risk is only found in firms with weak internal control and firms in poor legal system areas. Conclusions: Results of the study suggest that corporate integrity has a significant influence on behaviors of managers. Business ethics reduces the likelihood of managers to overstate financial performance and hide bad news, which leads to the low likelihood of future stock price crashes. Meanwhile, corporate integrity can supplement internal control and legal system in decreasing stock price crash risks.

This paper describes the quantitative determination of flavonoids, tannins and ellagic acid in the leaves from wild and cultivated variations of Rubus L. species (Rosaceae): raspberry (2 wild and 13 cultivars) and blackberry (3 wild and 3 cultivars). The content of flavonoids was analyzed using spectrophotometric (the Christ-M llers method) and HPLC analysis after acid hydrolysis. The content of tannins was determined by the weight method, with hide powder, described by German Pharmacopoeia 10 (DAB 10). Ellagic acid content was examined using the HPLC method after acid hydrolysis. Flavonoid content, determined using the Christ-Muller's method was higher for the blackberry leaves than for the raspberry leaves and varied between 0.46% and 1.05%. Quercetin and kaempferol were predominant in all samples analyzed using the HPLC method. The highest flavonoid content was found in the leaves of R. nessensis (1.06%); with results in all of the examined samples varying between 0.27% and 1.06%. The concentration of ellagic acid in all species was determined after acid hydrolysis and ranged from 2.06% to 6.89%. The leaves of raspberries are characterized by greater amounts of tannins (varying between 2.62% and 6.87%) than the leaves of other species. The results from this study indicate that the analyzed species are a rich source of flavonoids, ellagic acid and tannins, which may be used for the quality assessment of Rubus L. species leaves.

E-science refers to the large-scale science that will increasingly be carried out through distributed global collaborations enabled by the Internet. The Grid is a service-oriented architecture proposed to provide access to very large data collections, very large scale computing resources and remote facilities. Web services, which are server applications, enable online access to service providers. Web portal interfaces can further hide the complexity of accessing facility's services. The main use of synchrotron radiation (SR) facilities by protein crystallographers is to collect the best possible diffraction data for reasonably well defined problems. Significant effort is therefore being made throughout the world to automate SR protein crystallography facilities so scientists can achieve high throughput, even if they are not expert in all the techniques. By applying the above technologies, the e-HTPX project, a distributed computing infrastructure, was designed to help scientists remotely plan, initiate and monitor experiments for protein crystallographic structure determination. A description of both the hardware and control software is given together in this paper.
