Currently, environmental contaminants that can cause Aromatic types of hydrocarbons, less than 1% made of Aromatic Free kind of used products, soybean oil products with linseed oil with the products, rice products using a wide range of environmentally ecological ink since 2000 is released quickly. All materials used in printed material, if the green is the best way to print the composite materials in industrial applications, because each process on the print quality and productivity, there can be many differences in this experiment because it accounts for a large proportion in the print general ink in the ink section and the International color standards(ISO2846-1:2006) certified ecological ink were compared. Therefore, in this paper has the ink released from the same company, each common general ink and ecological ink in the same condition which results were focused on whether the emerging international color standard(ISO 2846-1:2006) recognized for environmentally ecological ink printed color reproduction of the actual offset(color reproduction) how conformity to ISO 12647-2 standard color on the basis of the offset would check Color Reproduction. Based on the results of the experiments of this study, given the ecological ink coated paper, uncoated paper both color difference and the gamut of the ISO 12647-2 standard is suitable for ecological ink, the ink's color gamut reproduction, even more than existing international standards, there is no confirmed that the correct color reproduction possible. Using environmentally ecological ink industries is expected to respond to environmental policy.

Porosity paper evidence is encountered in case of forgery, kidnapping, fraud and terrorist activity. The present study was designed to evaluate the effect of three chemical reagents (Ninhydrin, 1,8-diazafluoren-9-one (DFO), Iodine fuming) to the quality of developed latent fingerprints on porosity printing papers and newspaper. In case of printing papers, print quality was better with Iodine fuming method than Ninhydrin and DFO treatment to developing latent fingerprints. Developing latent fingerprint on newspapers was achieved with Iodine fuming processing. The processing of Iodine fuming followed by DFO and by using blue light (orange red filter) exhibited better results with Iodine fuming. Enhancement of latent fingerprint detection image using Digital Imaging System was achieved.

WPS(Wifi Positioning System) is a location determination technique that utilizes AP information scattered all over the real world. In general, the finger print technique is used for location calculations in WPS. However the finger print technique is a location determination technique that utilizes average values and has problems in the accuracy of the location determination. It also shows low performance of the system due to arithmetic operations. In this paper, the MSS(Max Signal Strength) method is proposed to resolve the existing problems in the finger print technique. The proposed method can reduce the operation time and improve the accuracy of the system under the same conditions. Test environments of the system is presented and the performance of the system is analyzed to verify the methods.

Part of SB latex in pre-coating color was substituted with newly developed starch-based bio-binder in order to investigate the effect of starch-based bio-binder in pre-coating color on the properties of coating color and coated paper. Smoothness and gloss of coated paper were decreased with the increase of bio-binder substitution ratio. Brightness and whiteness did not show the significant changes, but stiffness was improved with bio-binder. Ink set-off, dry-pick and wet pick were decreased with the increase of bio-binder substitution ratio. In general, when all SB latex is substituted with bio-binder, ink set-off, dry- and wet-pick were deteriorated. However, it was found that if the bio-binder substitution ratio is controlled below 50%, similar qualities with coated paper manufactured by the use of SB latex binder can be obtained.

Web development and Internet technology development bring many kinds of works to web. This is the main reason why XML, document standard is popular. XML in web can be used to express document template or standard. XML with java can be more powerful and general. For example, XML can be used to transmit data and to print data into the screen using Ajax in JSP(Java Server Page) and to make interfaces in android, which is useful to reduce development cycle. However, XML is not easy to learn for the novice. In this paper, we propose the easy and effective way to reduce the learning curve of XML and to make and use XML documents. For the purpose, we suggest template base XML document generation and we design and implement XML document generator based on Template. XML document generator of template-based provides user interface and layout of XML document. So, users can generate XML document easily and effectively.

The weather FAX machine is the one of necessary of safety navigation for ship. which is the machine which make the weather image by the receiving radio signal which is modulated using FSK method and transmitted on air by coast station. after Coast station scan the weather image and broadcast the image with black dot to 1500Hz and white dot to 2300Hz using FSK modulation. This paper implement weather fax machine using only general IBM-PC by software. By using IBM-PC we can make some good functions like print, edit, save etc. The modulated signal from SSB go into RS232C port via photo coupler not to give damage to PC. by using Timer Interrupt and RS232C serial interrupt, we can measure signal frequency and remake weather image. This paper use only IBM-PC with general SSB receiver which is widely spread on the ship. so this is very economic and possible to implement mutifunctions.

This paper presents a novel CPW-fed UWB monopole paper antenna made by paper and copper tape. Through the simulation, the optimized antenna design parameters were obtained, and an antenna having an omni-directional radiation pattern and a gain of 2.2 dBi or more in the UWB frequency band of 3.1-10.6 GHz was designed. The antenna was manufactured using general A4 paper and copper tape, and the measurement result satisfies the return loss of -10dB or less in the UWB frequency band and confirm that the return loss characteristic was maintained even when the antenna plane was bent by 3 mm in the longitudinal direction. The proposed antenna is a wearable device that can provide services in the UWB band, and can be manufactured inexpensively by printing it with a conductive print on paper. So it can be used as a wearable antenna for UWB communication in various application fields such as logistics and disposable terminals.

Microarrayer is used to make DNA chip and microarray that contain hundreds to thousands of immobilized DNA probes on surface of a microscope slide. This paper shows the develop-ment results for a printing type of microarrayer. It realizes a typical, low-cost and efficient microarrayer for generating low density micro array. The microarrayer is developed by using a prependicular type robot with three axes. It is composed of a computer-controlled three-axes robot and a pen tip assembly. The key component of the arrayer is the print-head containing the tips to immobilize cDNA, genomic DNA or similar biological material on glass surface. The robot is designed to automatically collect probes from two 96-well plates with up to 12 pens at the same time. To prove the performance of the developed microarrayer, we use the general water types of inks such as black, blue and red. The inks are distributed at proper positions of 96 well plates and the three color inks are immobilized on the slide glass under the operation procedure. As the result of the test, we can see that it has sufficient performance for the production of low integrated DNA chip consisted of 96 spots within $1cm^2$ area.

A general purpose ERP system is often unsuitable to manage the products of a small and medium enterprise. Thus, it is necessary to develop and use a system which is suitable for characteristic of an enterprise. In this paper, we implement a raw and subsidiary materials management system which controls the many products of an enterprise producing electrical wire. First, we design a database of raw and subsidiary materials information for production process. Second, we develop an automatic calculation module which computes the necessary quantify of materials to produce goods ordered. Third, the proposed system manages purchasing and selling data of raw and subsidiary materials in production process. Finally, we implement not only a history management module of storage and delivery, but also a print module of history summary report.
