  • Objectives : In this research, relatively the characteristic in the combustion according to the brands of the commercial indirect moxibustion is compared and the commercial indirect moxibustion is standardized and this result tries to be provided as necessary basic data. Methods : After adhering to the agarose gel surface in which the thermocouple is inserted, 6 kinds of commercial indirect moxibustion were burnt off and the burning behaviour of the commercial indirect device and heat quantity of stimulus was compared. Results : 1. The form of combustion did not have a difference in 6 kinds of commercial indirect moxibustion combustion. 2. As to the miximum temperature, 'Seoam' and 'Dongbang' was higher than 'Baekryoung' and 'Taeyang'. 3. It was long so that the highest temperature reaching time of 'Seoam' could note in comparison with the other brands. And the highest temperature reaching time of 'Baekryoung' was short to note in comparison with the other brands. 4. As to the quantity of heat stimulus, 'Seoam' was the biggest and 'Baekryoung' was the smallest. 5. The quantity of heat stimulus of 'Dongbang' was the most stable. Conclusions : In this research, relatively the form of combustion of 6 kinds of commercial indirect moxibustion and heat quantity of stimulus were compared. It desires to anticipate the result that it makes the skin.

  • In the current GPON market and standard, the line bit rate requirement is changing from 1.25 Gbps to 2.5 Gbps. We fabricate a 2.5 Gbps burst-mode receiver with commercially available blocks and optimize it with an APD bias control. A burst-mode measurement setup is made for the full compliance test with the GPON standard. The device meets the partially defined 2.5 Gbps specs in the current ITU G.984.2 standard, also, supports 1.25 Gbps specs for the coexistence issue in an access network. The full-compliant measurement values can be used as a guideline for fixing "for further study" specs in the current GPON standard at 2.5 Gbps.

  • NFPA-803 has been referred as the Fire Protection Standard at the Nuclear Power Plants of Pressurized Water Reactor. This Standard has been used as the fire protection regulation, containing prescriptive requirements with deterministic methodology. Recently, with cumulative efforts by the U.S. Nuclear Regulatory Commission and Utilities in America to establish a new Standard, including a quantitative evaluation methodology, NFPA-805, the Performance-Based Standard for FIRE Protection for Light Water Reactor Electric Generating Plants was issued and approved by the American National Standards Institute as an American National Standard with an effective date of February 9, 2001. This paper presents an analysis result from the computer modeling for the fire simulation In addition, it proposes the idea that this kind of analytic method can be available for the facilities design of fire prevention and protection fields, as well as an evaluation for the fire suppression system with a quantitative analysis for the thermal phenomena in fire compartments in Nuclear Power Plants.

  • This paper is intended to investigate the Build-up Method of SCM(Supply Chain Management) Connection applying EC Standard. SCM helps companies plan and supply to meet customer demand. SCM is the only solution available today that enables an organization to strategize, plan and execute a company's buy, make, move, store, fulfill and service business processes across multiple enterprises for total profitability. The research of modern scientists has thrown new light on the subject. However, the study of SCM for EC Standard has been strangely neglected by critics. Consequently, existing SCM systems, which require to introduce the functions of EC, need to be changed. Summarizations of the main points that have been analyzed in this paper are as follows:. the sharing information for connection and the Rosetta-net standard of the existing SCM system(Order management module(PIP 3A4) of the Rosetta-net specifications for connection by the Rosetta-net). Finally, it shows the process of the gateway for connecting among the existing SCM systems.

  • This research has designed and implemented the standard conformance test system for e-Business solutions that supports the ebXML, which is currently being focused on as the leading electronic commerce framework. The adoption of standards such as ebXML is probably the best way to achieve interoperability among electronic commerce systems, and more and more e-Business solutions around the world are supporting ebXML. This research primarily discusses the concept and needs for the standard conformance tests on e-Business solutions. The standard conformance test system is developed based on the detailed specifications of the ebXML framework. This system was used to test commercial e-Business solutions supporting ebXML. The system implemented in this research will provide a significant basis for the standard conformance certification of e-Business solutions, and could also provide clear decision criteria for e-Business solutions currently in market, thus activate the overall e-Business market.

  • The development of the Construction Production Rates System for appropriate construction cost calculation has recently come to the fore as a means of invigorating OSC based PC structure which currently needs institutional frameworks. PC structure based construction expenses consist of the factory-built assembly, transportation and on-site installation. Recently, in the field of transportation and site installation, research on product structure development is being conducted, such as presenting the standard product calculation system reflecting the results of field survey for each subsidiary materials (Lee et al., 2021). On the other hand, there is no ongoing research on estimating construction expenses of Factory-built assembly. This study suggests Construction Production Rates System which can be used for PC subsidiary materials based Factory-built assembly cost estimations. For the research, work types for the construction procedures have been categorized, and the standard input manpower suitable for the corresponding work characteristics has been derived from analyzing the associated Construction Standard Production Rates for each work type. Also, as the research referred PC subsidiary materials (such as columns, beams, walls, and slab, as well as on-site installation) and the standard number of workforce based on work types, one can calculate direct labor cost, using what the research shows. In addition, it suggests that the size of individual subsidiary materials be the extra cost factor, by using the characteristics that productivity changes depending on the size(m3) of subsidiary materials. It is expected that the research can contribute to objectively verifying factory-built assembly cost through of PC structure, which currently relies on estimates.

  • Meridian Research Center, Division of Standard Research, Keora Institute of Oriental Medicine Objectives : Ear acupuncture needle is used to treat smoking, drug abusing, alcoholism frequently over time stability of ear acupuncture needle is important factor for safe acupuncture treatment. In spite of the importance, there has been few study about the quality of disposable acupuncture needle tip - using scanning electron microscope (SEM) in 2002, 2003. Moreover, there was no study about ear acupuncture needle. Methods : The three ear acupuncture needle, made in China, Japan, Korea was chosen. We used Hank's solution at the 38$^{\circ}C$ as a phantom tissue liquid. Except for the control group, five groups of needles are soused one to five days. Surface corrosion was observed using the SEM compared with control group. Results : There was no particular corrosion in all groups of ear acupuncture needles compared with the control group. Conclusions : All of the ear acupunctures used in this study are stable in body fluids at least 5 days.
