This study was carried out to investigate the use patterns of traditional fermented soybean products(Jang) in Yangsan city. Two hundred eighty seven housewives living in Yangsan joined this survey practiced by Yangsan City Agricultural Development Center. 49.0% of these housewives graduated from a highschool, and 77.4% is in 30s or 40s. Most(69.3%) of respondents themselves have made Jang at home and the preparation frequency of Jang became higher with getting older. This survey showed that the preparation frequency of Jang in large family living with parents is higher than in nuclear family. The Jang preparation tendency of housewives living in the independent home was higher than that of apartment. Most of respondents replied the preparation method of Jang has been learned from mother or mother-inlaw. On the other hand, in the case of no making Jang at home, they bring it generally from relatives or buy it at the market. And 59.8% of housewives anted to participate in the education of Jang preparation.

Overproduction of L-ornithine by mutant strains isolated from Brevibacterium detoglutamicum BK1046 was investigated. The strain was a L-ornithine auxotroph and exhibited culture instability during fermentation. Through a sequential screening effort, a highly stable strain with lless revertant formation was finally selected and designated B. ketoglutamicum BK52 (KCTC0141BP). It prouduced L-ornithine at a high concentration (above 9 g/L) independent of subculture or cultivation time, and also had a very low tendency of revertant formation. In a long-term storage, this strain maintained its cell stability and productivity of L-ornithine to a reasonable range.

The purpose of this study was to explore the relationship of caregivers' accreditation experience and their motivational self-concept. Questionnaire were gathered from caregivers who work in Seoul, Incheon, and Kyunggi areas. Data were analysed by t-test, MCA, and multiply regression analysis. The result showed that caregivers who experienced accreditation at child are centers had higher scores in their motivational self-concept than caregivers who inexperienced accreditation procedure yet had. This tendency was clear in caregiver groups who work at unsupported child care centers, and who got certificate from institutions except college. With controlling individual background variables which influence on caregivers' motivational self-concept, independent effect of caregivers' accreditation experience on their motivational self-concept was still significant especially at the caregiver group who work in unsupported child care centers.

Purpose This paper tired to identify the consumers' tendency with individual features and social influence as the independent variables because of the importance of identifying the various needs of financial consumers in accordance with the expansion of new financial demands. Furthermore, this paper included the relative attraction of Fintech and switching cost from mobile banking to Fintech as the variables. Design/methodology/approach To analyze the empirical study, data was collected online by conducting the questionnaire survey with 247 individuals who had used the Fintech service. The study results would provide us with the understandings of the factors influencing on the customer satisfaction and switching value recognized by consumers in case of switching from the existing mobile banking to the Fintech service. Findings The results would provide useful implications to the academic and the practical fields including the Fintech enterprises expanding the activation of Fintech industry.

To find the effects of pressure on critical heat flux (CHF) for the conditions of low pressures (especially up to 10 bar) and low mass flux (~300 kg/$m^2$s), a series of experiments have been accomplished by using uniformly heated Inconel-625 tube. The experimental ranges are as follows: pressure (from 1.2 to 8 bar). mass velocities (from 100 to 250 kg/$m^2$s) and the inlet subcooling ($\Delta$h$_{i}$ ＝ 350 kJ/kg). According to the experimental data, it is found that the CHF is nearly independent of the pressure and increases with mass flux. From the results of the CHF correlation assessment for this experimental data, we could find somewhat different tendency of CHF behavior from every other CHF prediction correlation and table.ation and table.

Genetic algorithms are so named because they are analogous to biological processes. The model parameters are coded in binary form. The algorithm then starts with a randomly chosen population of models called chromosomes. The second step is to evaluate the fitness values of these models, measured by a correlation between data and synthetic for a particular model. Then, the three genetic processes of selection, crossover, and mutation are performed upon the model in sequence. Genetic algorithms share the favorable characteristics of random Monte Carlo over local optimization methods in that they do not require linearizing assumptions nor the calculation of partial derivatives, are independent of the misfit criterion, and avoid numerical instabilities associated with matrix inversion. An additional advantage over converntional methods such as iterative least squares is that the sampling is global, rather than local, thereby reducing the tendency to become entrapped in local minima and avoiding the dependency on an assumed starting model.

According to the passage of an age, a method which communicates each other between the city and space, and space and a human has changed. Recently, as the city is developing related with the public, the sphere and a territory of activity of a public has been wider in an environment of the city. Therefore, development of night scenery and the rise of a medium of a vision are accompanied with a new material and the high-technology. Innovation of abundant techniques tends to being surface and mass media, and breaks from the architectural aspect of space as mutual expansion of relations between interior and exterior, and making a boundary obscurely. Space design represents peculiarity of non-territorial which modern art, an advertisement, a media and a reflection are integrated as getting over above tendency. As we find out methods which the public can communicate with the space in wider territory, the public and the space can extend mutual relations and the design of modern space is been varying a part as the space which has a context of city and synthetic sociality for the public by avoiding independent objects.

The effects of the alloying elements and cooling rates on the formation of phosphide eutectics of compacted vermicular graphite cast irons containing copper, tin, molybdenum for producing pearlitic matrix, and also containing phosphorus and boron for increasing wear resistance, were investigated. The liquidus phosphide eutectic was found to solidify as a pseudo-binary phosphide eutectic, but with increasing of the cooling rate non-equlibrium phosphide eutectic with needle type carbide could be formed. However, the liquidus phosphide eutectic containing both phosphorus and carbide-forming boron was found to solidify always as a non-equlibrium phosphide eutectic with coarse carbide, independent from the cooling rate. It was also confirmed that the tiny isolated phase observed by SEM was gamma iron solid solution with phosphorus, silicon, molybdenum and the matrix containing these tiny islands was phosphide phase containing manganese and molybdenum. The addition of copper was found to decrease the tendency of forming ledeburitic carbides in the phosphide eutectic.

This study was designed to understand family economic well-being in Korea and to compare it with that in the U.S.A. The purpose of this study was to investigate the level of rural family life satisfaction in Korea and in the U.S.A. Specific objectives were: 1. To investigate the influence of independent variabels on rural family life satisfaction, 2. To analyze the influence of socioeconomic variables and social-psychological variables on rural family life satisfaction, and 3. To find commonalities and differences between the two countries. The data, collected from 471 Korean rural households and 301 households in two counties of Ilinois, a state in the U.S.A., were analyzed by frequency distribution, pearson's correlation, one-way analysis of variance, Scheffe test, and multiple regression analysis. The results are as follows: 1. The only common tendency is that the feeling of togetherness influences family life satisfaction in the two countries. 2. The social-psychological variables correlated with each other, and these variables considerably influence rural family life satisfaction in both countries. 3. Sex, number of family members, and no talk influence family life satisfaction differently in the two countries.
