Papaverine administration produced significant increases in acetylcholinesterase activity in cerebral cortex and striatum of rat brain. Two related compounds, tetrahydropapaverine and tetrahydropapaveroline, also gave similar effects. However, their actions seem to be indirect because papaverine has no in vitro effect on the enzymatic activity.

This study was performed to analyze a path model that investigated the relations among financial statements financial management and financial satisfaction of urban households. For this purpose conceptual framework based on the system theory was suggested. Empirical test's results showed some evidence has been provided that supported that conceptual frame-work. The level of living and gap between the level and standard of living measure were vital in the model investigating financial management and financial satisfaction, There were statistically significant direct effects of them on financial management however there were many indirect effects that mediate through them as well Also The financial management was accepted in the model investigating financial satisfaction. There was statistically significant direct effect on it and indirect effect that mediated through the financial management.

The purpose of this study is to examine the relationships among selected socioeconomic variables(age, household income, education duration; perceived income adequacy, gap between living standards and level), financial management and financial satisfaction. The sample size is 298 interviewee, and the unit of analysis is household in Seoul. Results of the study indicate that perceived income adequacy is significantly related to financial management. And perceived income adequacy, household income, gap between living standards and level, and age are significantly related to financial satisfaction. Although perceived income has an indirect effect on financial through financial management, but indirect effect is too small, financial management is not examined as intervening variable.

We developed a new RF indirect-heating LPE furnace. The thermal gradient of our newly developed furnace is less than that of direct heating, and is as gentle as that of the resistance-heating LPE furnace. With this new furnace, the heating and/or cooling is faster than that of the resistance-heating furnace. Impurity-doped YIG film was grown from a $PbO-B_{2}O_{3}$, based flux on a (111) GGG substrate. To study the effect of the impurities on the MSSW threshold power and the saturation response time, we used two microstrip lines to excite and propagate the MSSW at 1.9 GHz. The MSSW threshold power and saturation response time was found to be related to the $\Delta$H.

The purpose of this study was twofold: One was to investigate the structural relationships among communication with father and mother, ego-identity, and school adjustment. The other was to test the structural equivalence among researched variables between middle and high school samples. The subjects were 419 sophomores of middle and high schools. The major findings were as follows. 1) Communication with the father had direct and indirect effects on adolescents' school adjustment, while communication with the mother had only an indirect effect on school adjustment. 2) Ego-identity had a direct effect on school adjustment, and mediated the effects of communication with father and mother in school adjustment. 3) Multiple-group analysis revealed that middle and high school groups had the same structural relationships, but had different regression weights.

This study examined the cause-and-effect relationships among developmental network characteristics, developmental functions, and career identity. The study analyzed the data of employees with more than two years of experience and a college degree or over qualifications, from domestic companies. For analysis, the structural equation model was applied. Most of all, it was substantiated that the structural relationships among the developmental network characteristics, developmental functions, and career identity. The specific results were as follows. First, tie strength had a positive effect on all of developmental functions but psychosocial support mediated the relationship between the tie strength and career identity. Second, an indirect relationship between indicators of network diversity and identity was not found or the indirect relationship was very weak.

The indirect approach for measuring the bridge frequencies from the dynamic responses of a passing vehicle is a highly potential method. In this study, the effect of road surface roughness on such an approach is studied through finite element simulations. A two-dimensional mathematical model with the vehicle simulated as a moving sprung mass and the bridge as a simply-supported beam is adopted. The dynamic responses of the passing vehicle are solved by the finite element method along with the Newmark ${\beta}$ method. Through the numerical examples studied, it is shown that the presence of surface roughness may have negative consequence on the extraction of bridge frequencies from the test vehicle. However, such a shortcoming can be overcome either by introducing multiple moving vehicles on the bridge, besides the test vehicle, or by raising the moving speed of the accompanying vehicles.

These experiments were carried out ot detect autoantiboies to zona pellucida in sera from infertile women using indirect ELISA and IFA and to investigate their effect on in vitro fertilization of mouse ova. In inidirect ELISA test, 12 of 116(10.3%) serum samples form infertile women gave positive reaction whereas all of 16 samples from fertile women and men were negative. Furthermore, in indirect IFA test, 17 of 116 (14.7%) serum samples from infertile women gave positive fluorescence whereas all of control sera were negative fluorescence. The fertilization rates(15.9%) of mouse eggs treated with positive sera were significantly lower than those(51.9%＋71.2%) autoantibodies to zonapellucida are responsible for infertility in unexplained infertile women, presumably by perventing sperm attachment and penetration.

For the analysis of radiating noise problems in medium-to-high frequency ranges, the Energy Flow Boundary Element Method (EFBEM) was developed. EFBEM is the analysis technique that applies the Boundary Element Method (BEM) to Energy Flow Analysis (EFA). The fundamental solutions representing spherical wave property for radiating noise problems in open field and considering the free surface effect in underwater are developed. Also the directivity factor is developed to express wave's directivity patterns in medium-to-high frequency ranges. Indirect EFBEM by using fundamental solutions and fictitious source was applied to open field and underwater noise problems successfully. Through numerical applications, the acoustic energy density distributions due to vibration of a simple plate model and a sphere model were compared with those of commercial code, and the comparison showed good agreement in the level and pattern of the energy density distributions.

The purpose of this study was to assess the causal relationships of attitude toward fish eating, health involvement, convenience, fish consumption and age. A total of 235 questionnaires were completed. Structural equation model was used to assess the causal relationships among constructs. Results of the study demonstrated that the structural equation analysis result for the data also indicated excellent model fit. The influences of age on health involvement and convenience were statistically significant. The influences of health involvement on attitude toward fish eating and fish consumption behavior were statistically significant. The influence of convenience on fish consumption behavior were statistically significant. Moreover, the age had a significant indirect effect on attitude toward fish eating through health involvement. The age also had a significant indirect effect on fish consumption behavior through convenience.
