Single PPM Quality Innovation Movement is originally developed quality program in Korea for supplier's quality level-up since 1995. The quality target is below the 10ppm(parts per million) in outgoing quality and delivered goods plus field claim. This Single PPM Quality Innovation Movement program was conducted to realize the anticipated results not only due to management result level's increasing, but also the company's confidence and competitiveness. This study attempted to find the mutual influences on the participation of the constituent members, satisfaction of the constituent members and results of the management from Single PPM Quality Innovation Movement. The reliance analysis for the measurement material on the questionnaire was verified by Cronbach's alpha coefficient. Participation of the constituent members, satisfaction of the constituent member and result of the management, the influences upon Single PPM improvement degree level were verified through the structural analysis by using SPSS statistic package. The influence evaluation among the groups was evaluated by the structure equation.

The purpose of this study was to investigate the effects of angular velocity on muscle strength and blood constituent. Subjects was classified into two groups, which were $60^{\circ}/sec$ angular velocity group (n=8), and $240^{\circ}/sec$ angular velocity group (n=8). Each group was applied to perform the isokinetic exercises on extensor muscle group for each 7 times in 10 set (3 days per a week for 3 weeks). Muscle strength was measured using peak torque of quadriceps femoris and blood constituent was measured using RBC, WBC and Hb. The peak torque was more significantly increased after 3 weeks application of $60^{\circ}/sec$ angular velocity group than $240^{\circ}/sec$ angular velocity group. The RBC and Hb were more significantly increased after 3 weeks application of $60^{\circ}/sec$ angular velocity group than $240^{\circ}/sec$ angular velocity group. But WBC was more significantly increased after 3 weeks application of $240^{\circ}/sec$ angular velocity group than $60^{\circ}/sec$ angular velocity group. These results indicate that $60^{\circ}/sec$ angular velocity isokinetic exercise application were effective treatment strategy on increase of muscle strength. But $240^{\circ}/sec$ angular velocity isokinetic exercise application were effective treatment strategy on immune protect system.

The results of documentary survey of 81 prescriptions of Hwangnyeonhaedok-tang and Hwangnyeonhaedok-tang blended ones introduced in Dongeuibogam in which there are 42 of prescriptions using Hwangnyeonhaedok-tang as main constituent and 39 of prescriptions using Hwangnyeonhaedok-tang as assistant constituent can be summarized as followings, 1. Hwangnyeonhaedok-tang blended prescriptions using Hwangnyeonhaedok-tang as main constituent are applied to 20 categories of disease such as 7 of external disease from the chapters of various dermatos is, various injury, tumor(16.6%), 5 of fire disease from the chapter of fire(12%), 5 of eye diseases from the chapter of eye(12%), 4 of disease originated from damage by coldness from the chapter of coldness(9%), etc. 2, It has been found that mainly considered causative agents in diseases, when making up Hwangnyeonhaedok-tang blended prescriptions using Hwangnyeonhaedok-tang as main constituent, are feverish toxin in internal organs, followed by exogenous damp and fever, feverish toxin from damage by coldness and more such as extravasated blood, damp toxin, lack of ki and blood, lack of yin, congestion, the seven passions, blood overflow and excess liquor and sex.

Experiments on deactivation kinetics of immobilized lipase enzyme from Candida cyl-indracea were performed in stirred bath reactor using rice bran oil as the substrate and temperature as the deactivation parameter. The data were fitted In first order deactivation model. The effect of temperature on deactivation rate was represented by Arrhenius equation. Theoretical equations were developed based on pseudo-steady state approximation and Michaelis -Menten rate expression to predict the time course of conversion due to enzyme deactivation and apparent half-life of the immobilized enzyme activity in PFR and CSTH under constant feed rate polity for no diffusion limitation and diffusion limitation of first order. Stability of enzyme in these continuous reactors was predicted and factors affecting the stability were analyzed.

A series of alternating and alternating block copolycarbonates containing the constituent groups of polysulfone was synthesized through a multi-step solution condensation method. For the regulation of block length, monodisperse oligomers were prepared by using a large excess of the bisphenols and were subsequently incorporated into the copolymer chains. Separating the unreacted bisphenols from the oligomers by dissolution/precipitation steps took advantage of solubility differences. The structures of the monomers, oligomers, and copolymers were characterized and confirmed by GPC, NMR spectroscopy, mass spectrometry, and elemental analysis. Monodispersity of the oligomers, which is critical for control over the block length in the copolymers, was confirmed by GPC and mass spectrometry. Of the two constituent groups of the polysulfone, the sulfone linkage stiffens the polycarbonate copolymer chain, while the ether linkage softens it.

Lesson plan sheets were collected from letter communication of each local junior and senior high school as well as from literature. These lesson plan sheets were arranged and investigated for items of constituent element and types. The results were summarized as follows. 1. The organization of plans were constituted of three frames as early plan, unit plan, and hour plan. 2. The lecture and inquiry types among the collected lesson plan sheets showed 91.9% and 8.3% in junior high school as well as 87.9% and 3% in senior high school, respectively. The mixed types did not find out in junior high school, however the mixed types showed 9.1%in senior high school. 3. The items of constituent elements in lesson plan sheets were varied by the contents and the kinds of teaching unit in science education of secondary school.

Candida cylindracea lipase was immobilized by adsorption on acid washed glass beads. It was observed that protein loading of the support depends on the size of the particle, with smaller particle containing higher amount of protein per unit weight. Initial reaction rate linearly varied up to enzyme concentration of 17.25 U/mL. Amount of free fatty acids produced was linearly proportional up to the enzyme loading of 1650 $\mu$g/g of bead. Achievement of chemical equilibrium took longer time in the case of less protein loading. Degree of hydrolysis was found to decrease in second and third consecutive batch operations on repeated use of immobilized lipase.

In the present paper, glass fibers are substituted partially with monofilament fishnet and polyester matrix for making the composites. The composite specimens were prepared in accordance with ASTM for analyzing the flexural strength and dynamic mechanical properties. Furthermore, machinability revealed the interaction of glass fiber and partial substituted monofilament fishnet fiber with the matrix. Fiber pullouts on the fractured specimen during the physical testing of the composites are also investigated by COSLAB microscope. The results reveal that the fishnet based composites have appreciably higher flexural properties. Furthermore, the glass fiber, woven roving and fishnet composite has more storage modulus and significant mechanical damping. The composite specimens were fabricated by hand lay-up method. Hence, these composites are the possible applications to develop the value added products. The results of this study are presented.

In the course of screening anti-adipogenic activity of natural products employing the preadipocyte cell line, 3T3-L1 as an in vitro assay system, the EtOAc fraction of the stem barks of Acer tegmentosum Maxim (Aceraceae) showed significant inhibitory activity on adipocyte differentiation as assessed by measuring fat accumulation using Oil Red O staining. Activity-guided fractionation led to the isolation of active constituent, (+)-catechin. (+)-Catechin showed inhibitory activity on adipocyte differentiation in dose-dependent manner. Further studies with interval treatment demonstrated that (+)-catechin exerted inhibitory activity on adipocyte differentiation via acting on early stage of adipogenesis. Our present study also showed that (+)-catechin significantly inhibited the preadipocyte proliferation. Taken together, these results suggest that (+)-catechin, a constituent of A. tegmentosum might contribute the anti-adipogenic activity of A. tegmentosum.
