The pneumatic classification and acidic leaching behaviors of phosphor sludge have been examined to establish the recycling system of rare earth components contained in waste fluorescent lamp. At first, separation characteristic of rare earth components and calcium phosphate in phosphor sludge was investigated by pneumatic classification. After pneumatic classification of phosphor sludge, rare earth components were leached in various acidic solutions and sodium hydroxide solution. For recovery of soluble component in leaching solution, rare earth components were separated as hydroxide and oxalate precipitations. The experimental results obtained are summarized as follows: (1) In classification process, rare earth components in phosphor sludge were concentrated to 29.3% from 13.3%, and its yield was 32.9%. (2) In leaching process, sulfuric acid solution was more effective one as a leaching solvent of rare earth component than other solutions. Y and Eu components in phosphor sludge were dissolved in sulfuric acid solution of 1.5 k㏖/㎥, and other rare earth components were rarely dissolved in leaching solution. Leaching degrees of Y and Eu were respectively 92% and 98% in the following optimum leaching conditions; sulfuric acid concentration is 1.5 k㏖/㎥ , leaching temperature 343 K, leaching time 3.6 ks and pulp concentration 30 kg/㎥. (3) Y and Eu components of phosphor sludge contained in waste fluorescent lamp were, effectively recovered by three processes of pneumatic classification, sulfuric acid leaching and oxalate precipitation methods. Their recovery was finally about 65 %, and its purity was 98.2%.

Rice plants are subjected to various forces such as natural force of wind and mechanical force of cultivating machines. Rheological behavior of the rice stem can be expressed in terms of three variables : stress, relaxation and time. The objectives of this study are to examine stress relaxation, creep and recovery characteristics on the rice stem in case of axial and radial loading. Stress relaxation with time was studied on three levels of loading rate and on four levels of applied stress. The results were summarized as follows : 1. The hysterisis losses of the rice stem distinctly observed at the radial compression in comparison with axial compression. The hysterisis loss implied that the stem to absorbed energy without being deformed beyond the yield point. 2. Ageneralized Maxwell model consisting of three elements gave a good description of the relaxation behavior of the rice stem. Rate of loading was more significant on the observed relaxation behavior within the short relaxation time, but there were little influences of rate of loading on the relaxation time. 3. The stress relaxation intensity and the residual stress increased in magnitude as the applied stress increased, but the relaxation time was little affected by the applied stress. 4. The coefficients of the stress relaxation model showed much differences in the radial compression and the axial compression, especially the higher relaxation stress of the third element was observed in the radial compression. 5. The behaviors of rice stem in creep and recovery test also might be represented by a four element Burger's model. But the coefficients of the creep model were different from those of the recovery model. 6. The steady-state phenomena of creep appeared at the stress larger than 20 MPa in Samkang and 1.8 MPa in Whajin. 7. The elastic modulus of the stem showed the range from 40 to 60 MPa. It could be considered, as a result, the rice stems had viscoelastic properties.

Influence of a silane coupling agent on the reatraction behaviors of NR vulcanizates reinforced with carbon black and c lay was studied. Bis-(3-(triethoxysilyl)-propyl )-tetrasulfide (TESPT) was used as a silane coupling agent. The vulcanizates containing the silane coupling agent were, on the whole, recovered faster than those without the silane coupling agent. However, for the vulcanizate with the higher clay content at low temperature region (below $-12^{\circ}C$), the vulcanizate containing the silane coupling agent was recovered slower than that without the silane coupling agent. The recovery difference of the vulcanizates with and without silane coupling agent decreased with increase of clay content. The experimental results were explained with crosslink density, modulus, and bound rubber content.

In order to produce the single chain precursor of a novel human insulin analogue, (B30-Homoserine) insulin, the fermentative behaviors of Escherichia coli JM103 were studied, which harbors pKBA plasmid carrying a hybrid gene in which the gene for a single chain precursor was fused with lacZ gene under tac promoter. The maximal induction of gene expression was achieved when more than 0.05 mM of isopropyl-$\beta$-D-thiogalactopyranoside(IPTG) was supplemented to fermentation medium after 4 h cultivation of E. coli, and followed by longer than 2-h fermentation. The hybrid protein of the single chain insulin precursor was isolated from cytoplasmic inclusion bodies by dissolving in 8M urea solution, and purified through DEAE-Sephacel and Sephadex G-200 column chromatographies with a recovery of 35%. The finally purified hybrid protein showed a single band on sodium dodecyl sulfate-polyacrylamide gel.

Non-proportional loading tests of Nylon 66 at room temperature exhibit path dependent behavior and plasticity-relaxation interactions. The uniaxial formulation of the viscoplasticity theory based on overstress (VBO), which has been used to reproduce the nonlinear strain rate sensitivity, relaxation, significant recovery and cyclic softening behaviors of Nylon 66, is extended to three-dimensions to predict the response in strain-controlled, comer-path tests. VBO consists of a flow law that is easily written for either the stress or the strain as the independent variable. The flow law depends on the overstress, the difference between the stress and the equilibrium stress that is a state variable in VBO. The evolution law of the equilibrium stress in turn contains two additional state variables, the kinematic stress and the isotropic stress. The simulations show that the constitutive model is competent at modeling the deformation behavior of Nylon 66 and other solid polymers.

Service Encounter employees play a crucial role in service delivery and building relationships with customers and their attitudes and behaviors towards customers determine customers' perceived service quality and satisfaction. Past research indicates that TQM managerial practices are a critical determinant of employee's attitude and performance in the workplace. Therefore, this study investigates a model examining the relationship among TQM, employees' attitude and service performance in a hospital. Our measurement results were acceptable in terms of reliability and validity. The statistical testing shows significance on the positive relationship in the sequential order of TQM, employee's attitude and service performance. In conclusion, the theoretical and practical implications of this study were discussed, along with its limitations.

High temperature deformation behavior of Al85Ni10Y5 alloy extrudates fabricated with amorphous ribbons was investigated at temperature range form 300 to 550$^{\circ}C$ by torsion tests. Thermal properties of amorphous ribbons as a function of aging temperature was studied by Differential Scanning Calorimetry(DSC). The Al phase crystallite firstly formed in the amorphous ribbons and its crystallization temperature(Tx) was ∼210$^{\circ}C$. During the processings of consolidation and extrusion, nano-grained structure was formed in the Al85Ni10Y5 alloy extrudates. The as-extrudated Al85Ni10Y5 alloy and the Al85Ni10Y5 alloy annealed at 250$^{\circ}C$ for 1 hour showed the flow curve of DRV(dynamic recovery) during hot deformation at 400-550$^{\circ}C$. On the other hand, the Al85Ni10Y5 alloy annealed at 400$^{\circ}C$ for 1 hour showed the flow curve of DRX(dynamic recrystallization) during hot deformation at 450-500$^{\circ}C$.
