As use of construction equipment has been increasing continuingly, the proportion of equipment expense to the total construction cost has become higher. However, there is a difference between the equipment expenses section in 'Poom-Sam' and practical data, because 'Poom-sam' does not consider non-working days due to weather conditions, legal holidays and management conditions. Therefore, 'Poom-Sam' does not present a reasonable standard for estimating construction equipment expenses. In this study, to estimate realistic construction equipment operating hours, firstly, construction equipment was classified according to work, and weather conditions, in which each work could not be executed, were established. Then, weather data on Seoul and Busan($2004{\sim}2006$) and legal holidays were analyzed to suggest annual standard operating hours. The annual standard operating hours of earthmoving & excavating, compaction, and drilling equipment was estimated to be 1,430 hours, and lifting equipment, concrete paving equipment, asphalt paving equipment, concrete equipment, and crushing & conveying equipment were estimated to be 2,124 hours, 1,156hours, 1,188hours, 1,688hours, and 2,152hours respectively.

The demand of diesel engine on the construction equipment has been rapidly increased because of thermal efficiency and power. But some of the construction equipment is imported from other country, since the their demands are not so large as compared with the other construction equipment. The imported construction equipments will be tested for emission with standard measurement mode. This study was conducted to measure emission characteristics of the construction equipment with changed standard measurement experimentally.

The emission standard of diesel engine on the construction equipment has been rapidly enhanced in advanced countries, because most of air pollutions was caused by construction equipment. So, all of the construction equipments will be tested for emission with standard measurement mode. But, the standard measurement mode of construction equipment is different for non-road and one for the road in korea. This study was conducted to measure emission characteristics of the construction equipment with changed standard measurement mode and to improvement the emissions experimentally.

As multidisciplinary marine research is actively conducted, various types of marine research facilities and equipment are purchased every year. However, among marine research facilities and equipment, it is difficult to classify and manage various types of field observation equipment used for environmental data collection and sample collection under the current national research facility and equipment standard classification system. In the case of Korea Institute of Ocean Science and Technology, about 30% of research facilities and equipment are unclassified and not properly managed. In this study, marine research facilities and equipment are classified into 7 middle and 36 sub-classes according to their characteristics. It is proposed to add a large classification group called 'Environmental Observation/Analysis Equipment', to the national research facility equipment standard classification system. In addition, it is proposed to classify the equipment operated in the laboratory among marine research facilities and equipment according to the existing national research facility equipment standard classification system. Through this, it is expected that all of Korea's marine-related research facilities and equipment can be systematically classified and managed effectively.

Construction equipment cost is critical to estimate the total construction costs, particularly in large and complicated projects. Despite its importance, the construction equipment cost may not reflect the current market value since the equipment database is being updated every 6 years at most. To keep construction equipment cost up to date, it is highly recommended to use the standard market price that is reported each year by the Ministry of Security and Public Administration (MOSPA). However, there is still a gap to adopt the standard market price system for the construction equipment cost computing system. Therefore, this paper suggests an effective way to develop a construction equipment cost estimation system.

This study aims to investigate and improve the present state of technical standard on building mechanical system in Korea. At this point be tormented the energy depletions are big problem on the rise. Building mechanical system is configured air conditioning, sanitation, urban equipment. In the design of equipment, installation, maintenance, applies to all devices in the field of industrial equipment and general engineering equipment field are within bounds to say that all of the equipment field. However, domestic technology level is still fly short of international standards in architecture, we spent much energy. Because of this, find the current situation and identify the problems look up ways to improve them.

This descriptive study was conducted in order to develop a standard criteria for nursing laboratory facilities and equipment for use by the 3 year nursing colleges. The data was collected from Aug. 28 to Sept. 30, 1997 by mail from 44 3 year nursing schools. To develop a standard criteria, the syllabi for Fundamentals of Nursing laboratory and for Physical Assessment were collected and analyzed. The following information was elicited and analyzed by the researchers : 1. for each procedure in the syllabus, the percentage of schools using the procedures 2. the facilities and equipment recognized as necessary and the percentage of schools which possess each item 3. calculation of the standard criteria for size of the nursing laboratory together with a list of the necessary facilities and equipment. The results of the study were as follows : 1. The Size of facility was 181.2m2 for fundamentals of Nursing laboratory and 56.4m2 for the storage room. For those whose number of students exceed 120, 1.98m2 is required for each students. 2. The number of items included in the standard criteria was 92 for Fundamentals of Nursing and Physical Assessment and 47 for other nursing subjects. The items made of rubber, plastic and the disposable ones were suggested but excluded from the standard criteria. Based on the above findings, the following suggestions were made : 1. Periodic review of the standard criteria is necessary to update the standard. 2. A study on the standardization of the curriculum for basic science laboratory, including experiment and a standard criteria of equipment, is necessary. 3. A study to develop a computer program for management of nursing laboratory facilities and equipment is needed.

In this paper, we propose a development method of portable Automatic Test Equipment based on PXIe platform. Legacy VME form factor structured test equipment has limited reuse and expansion of modules due to unapplied bus specification. In particular, these limitations can cause development periods and costs to increase, and the reliability of environmental conditions is lacking due to non-standard modules. The test equipment of the proposed PXIe platform can use diverse COTS modules to shorten the development period and minimize the instability between developments. The PXIe development module works with standard Xilinx FPGAs, PXIe Windows device drivers, and applications on standard PXIe buses. The use of standard bus and COTS modules increases scalability and reusability, enabling rapid development and excellent maintenance. Through the test, we show the proposed test equipments can be implemented efficiently between the development processes and proved their reliability through function tests and environmental tests.

One of the problems with the base station equipment is that there is a large difference between the replacement time of the hardware equipment such as the base station equipment and the radio access equipment, and the evolution period of the communication standard. Therefore, the base station communication platform must be flexible enough to handle the evolving communication standards after purchase. Recent research on reconfigurable communications platforms has focused on the efficient architecture of the communications platform to meet these requirements through software downloads while still using existing hardware. This paper presents a prototype of a base station communications platform based on the ETSI standard reconfigurable architecture. The communication platform presented in this paper is implemented as an ETSI standard reconfigurable architecture using a general-purpose DSP (Digital Signal Processor). In the implemented prototype, we verify the real-time feasibility of communication protocol updates through software reconfiguration.
