이신영,이학수 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A

This study was carried out to screen the effective polymeric additives preventing wall growth during mycelial submerged cultivation of Ganoderma. ludicum. Effects of additives on mycelial growth and exo-polysaccharide (EPS) production in flask culture and jar fermenter system under 3 different pH processes were investigated, and changes of mycelial morphology were also examined. From flask culture of G. lucidum wish additives of different concentrations, 0.1%(w/v) polyacrylic acid was effective for EPS production. As the polyacrylic acid of 0.1%(w/v) was added in medium, wall growth of G. lucidum mycelium grown in jar fermenter system could be protected. The addition of 0.1%(w/v) polyacrylic acid to medium was also improved the mycelial growth and EPS production in the later of submerged culture G. lucidum and no changes of mycelial morphology were observed.

A reasonable analysis of cutting force in end milling may give much advantage to improvement of productivity and cutting tool life. In order to analyze cutting force, the cutting dynamics was modelled mathematically by using chip load, cutting geometry, and the relationship between cutting forces and the chip load. Specific cutting constants of the cutting dynamics model were obtained by average cutting forces, tool diameter, cutting speed, feed, axial depth, and radial depth of cut. The model is verified through comparisons of model predicted cutting forces with measured cutting forces obtained from machining experiments. The results showed good agreement and from that we could predict reasonably the cutting forces in end milling.

In order to predict vibration during end-milling, the cutting dynamics was modelled by using neural network, and combined with structural dynamics by considering dynamic cutting states. Specific cutting constants of the cutting dynamics model were obtained by averaging cutting forces and tool diameter, cutting speed, feed, axial depth, radial depth were considered as if machining factors. Cutting forces by tests and by neural network simulation were compared and the vibration during end-milling was simulated.

Nonlinear dynamic system of a elastic pendulum system under random excitations was modelled by using the Lagrangian equations of motion which uses the kinetic and potential energy of a target system. The responses of random excitations were calculated by using Monte Carl simulation which uses the series of random numbers. The procedure of Monte Carlo simulation is generation of random numbers, system model, system output, and statistical management of output. linearize non-linear structural characteristics but the parametric excitation was used as it was given. The result were compared with the order of nonlinear terms which were considered in the calculation of responses.

The purpose of the study was to examine determinants of utilization in health and welfare services among the elderly who were recognized non-grade for long-term care insurance. The respondents were 411 elderly who were 65 years and older. The data were analyzed by statistical methods as frequency, chi-square test, and logistic regression analysis. The results of this study were as follows. First. 66.2% of the elderly used home care service, 52.6% used home-visiting health service, 29.7% used various welfare services. Second, presence of caregiver, subjective economic level, beneficiary of public assistance, numbers of diseases were significant predictors of total home care services for the elderly. Third, subjective economic level and instrumental daily living ability were significant predictors of home visiting health services.

We should maintain the maximum operation capacity for production facilities and find properly out the fault of each equipment rapidly in order to decrease a loss caused by its failure. The acoustic signals of a machine always carry the dynamic information of the machine. These signals are very useful for the feature extraction and fault diagnosis. We performed a fundamental study which develops a system of fault diagnosis for a pump. We obtained noises by a microphone, analysed and compared the signals converted to frequency range for normal products, artificially deformed products. We tried to search a change of noise signals according to machine malfunctions and analyse the type of deformation or failure. The results showed that acoustic signals as well as vibration signals can be used as a simple method for a detection of machine malfunction or fault diagnosis.
