The conventional way of molten nugget size measurement in welding process have utilized the metal-microscope by examining the micro sectioned weld specimen after micro-etching procedure. This paper proposes a new method for exact measurement of molten nugget size with the aid of the digital image processing unit and some developed software. This method proved to be convenient and precise in that resulting resolution and accuracy are as good as that of the conventional method.

흙-수분 특성곡선은 토질역학에서 불포화토의 근간이 되는 중요한 물성함수로 불포화토 연구에 있어서 가장 중요한 요소이다. 따라서 이러한 흙-수분 특성곡선을 보다 정확하고 빠르게 또 편리하게 측정할 수 있는 신뢰성 있는 방법이 불포화토 연구에 있어서 우선적으로 요구되고 있다. 본 연구에서는 피스톤 펌프 기법을 이용한 흙-수분 특성곡선 측정방법을 보완, 발전시켰다. 이 방법은 기존의 흙-수분 특성곡선 측정방법들보다 측정하기에 편리하고 빠르며 더욱 정확한 측정이 가능하다. 또한 전체실험 과정을 통하여 완전한 통제가 가능하며 컴퓨터를 이용한 자동화 및 정밀측정이 가능하기 때문에 흙-수분 특성곡선의 상세한 부분까지 연구할 수 있다. 한 점 한 점이 아닌 연속적인 건조곡선이나 습윤곡선의 측정이 가능하고 건조곡선에서의 공기침입값 위치라든지 습윤곡선에서의 공기폐색위치등도 측정 가능하다. 또한 불포화토의 특성중의 하나인 흙-수분 특성곡선의 이방성 측정도 가능하다. 본 연구에서는 실험방법상의 기법을 개발했을 뿐만 아니라 실험결과에 대한 구체적인 해석도 이루어졌다. 실례로 석션조절기법(suction drop measurement)이라는 방법을 개발했으며 이 방법을 이용하면 흙-수분 특성곡선을 보다 편리하고 또 짧은 시간 내 정확하게 측정할 수 있다.

The demands of complicated data communications have issued a new challenge to port logistics systems. Customers expect ports to handle their generated administrative data while a vessel is docked in a port. One port logistics system, known as the Vessel Clearance Process (VCP), manages large numbers of documents related to port of entry. In the VCP, information flows through many organizations such as the port authority, shipping agents, marine offices, immigration offices, and others. Therefore, for effective management of the Business Process (BP) of the VCP, a standardized method of BP modeling is essential, especially in heterogeneous system environments. In a port, according to port policy, terms and data are sued that are similar to but different from those of other logistics partners, which hinders standardized modeling of the BP. In order to avoid tedious and time-consuming document customization work, more convenient modeling of BP for VCP is essential. This paper proposes an ontology-based process similarity measurement to assist designer for process modeling in port domain, especially VCP. We expect that this methodology will use convenient and quick modeling of port business processes.

Monte Carlo simulation(MC) method was used as an uncertainty assessment tool for gas flow measurement in this paper. Uncertainty sources for gas flow measurement were analyzed, and probability distribution characteristics of each source were discussed. Detailed MC methodology was described including the effect of the number of simulation. The uncertainty result was compared with that of the conventional sensitivity coefficient method, and it was revealed that the results were different from each other for this particular gas flow measurement case of which the modelling equation was nonlinear. The MC was comparatively simple, convenient and accurate as an uncertainty assessment method, especially in cases of complex, nonlinear measurement modelling equations. It was noted that the uncertainty assessment method should be selected carefully according to the mathematical characteristics of the measurement.

The laser interferometer has been used for measurement of the micro displacement error. Although the laser interferometer is widely accepted as a tool for measurement of motion accuracy, the set-up procedure is time-consuming because of the strict requirement on alignment between a laser head and optic units. This paper addresses the development of a laser interferometer to measure the micro displacement for a micro machine. The portable laser interferometer which integrates a laser probe and optics, is developed for the convenient measurement. For the experiment, moving mirror set up on the micro stage. The velocity decoding board is also added to calculate doppler shift frequency directly. The output signal is obtained and analyzed by LabView. Finally experiments are found out the relation between micro displacement and output signal.

The traditional mechanical manometer is improved to develop more convenient and precise manometer in continuous measurement of the gas pressure in medium-low vacuum range (1x10$^{-1}$ -10 Torr.) Glass (solid) is used as a detector material of the improved manometer. Using the strain gauge adhered to thin glass board, mechanical strain corresponding to variation of pressure in measurement system is converted into quantity of electricity, and the quantity of electricity is amplified. Experiments have also shown that the improved manometer have more advantages in reproducibility, measured sensibility, and responsible velocity than taditional one.

This paper describes a systein which enables a fast 3 -dimensional profile measurement using a slit-ray projection method. One distinctive feature of this system is that a real-time video is processor is employed in order to reduce the amount of image data to be processed without eliminating essential information. Experimental results show that a calibrating method presented for the TV camera and the slit-ray projector is convenient and enables sufficient accurate measurements.

In the analysis of the mass distribution and SMD(Sauter Mean Diameter), planar laser imaging technique is a convenient and useful one when compared to the mechanical pattemator or PDPA (Phase Doppler Particle Analyzer). But recorded signals at cameras and intensity of laser are distorted by attenuation. Using experimental datum and assumptions, we study measurement errors due to attenuation in plannar image technique.

The Power measurement that can measure a single quantity does not smooth to install a system, and are not convenient to use. These measuring values are vary difficult for mutual operation and analyzing, and that have too many problems to compile measured databases. If each single measured values are mutual assist, correction and reform, the system will be able to be improved by minimizing differences between measure quantities and as making many different measurement system (Voltage, Current, Power and Resistor) is installed in one system. This study is useful to develope the power measurement system that is easier to analyze and management by database all of the parameter values because the power measurement system is able to be interbased with PC as requirement of industralization and information age.
