The purpose of this study was to examine the effect of social support on compliance to dietary regimen in noninsulin-dependent diabetes mellitus. Two hundred eighty six adult non-insulin dependent diabetics from Seoul, Kyonggido, Kyongsangbukdo participated in the study. Researchers, dieticians, graduate students majoring in nutrition interviewed patients with a pre-structured questionnaire during June in 1998. The questionnaire included items about demographic factors, general characteristics about diabetes. social support, and compliance to dietary regimen. Descriptive statistics, t-test, ANOVA and Pearson's Correlation were used to analyze the data. The mean scores of support from family was 27.0(0∼44). support from relatives, friends, and colleagues was 14.7(0∼32). Mean score of intangible support from family was 19.9(0∼32) and 12.0(0∼24) from relatives, friends, and colleagues. Mean score of tangible support from family was 7.1 (0∼12) and 2.6(0∼8) from relatives, friends, and colleagues. The mean scores for compliance to dietary regimen was 31.6(0∼42). Regardless of type and source, there was significant(p<0.01) correlation between social support and dietary compliance. Therefore, inclusion of family members in nutrition education for diabetics is essential. It is necessary to find ways to increase social support from relatives, friends, and colleagues.

A new family of structure-dependent integration methods is developed to enhance with desired numerical damping. This family method preserves the most important advantage of the structure-dependent integration method, which can integrate unconditional stability and explicit formulation together, and thus it is very computationally efficient. In addition, its numerical damping can be continuously controlled with a parameter. Consequently, it is best suited to solving an inertia-type problem, where the unimportant high frequency responses can be suppressed or even eliminated by the favorable numerical damping while the low frequency modes can be very accurately integrated.

This research purposed to analyse the diversity of the long-term care system based on the dependency/independency of the aged. For this purpose, we divided the long-term care systems to three components; form of benefit, generosity of benefit and delivery system. Form of benefit is whether the benefit is cash or in-kind, and the generosity of benefit is related to the level and coverage of benefit. The last concerned to focus on provider and user selection. According to this, we tried to make an ideal type of long-term care in the perspective of citizenship and consumerism. As a result, we established four types of long-term care system; active citizen type, passive citizen type, latent citizen type, and family dependent type. And we investigated Austria, Sweden, Germany and Korea for each type empirically.

A novel family of controllable, dissipative structure-dependent integration methods is derived from an eigen-based theory, where the concept of the eigenmode can give a solid theoretical basis for the feasibility of this type of integration methods. In fact, the concepts of eigen-decomposition and modal superposition are involved in solving a multiple degree of freedom system. The total solution of a coupled equation of motion consists of each modal solution of the uncoupled equation of motion. Hence, an eigen-dependent integration method is proposed to solve each modal equation of motion and an approximate solution can be yielded via modal superposition with only the first few modes of interest for inertial problems. All the eigen-dependent integration methods combine to form a structure-dependent integration method. Some key assumptions and new techniques are combined to successfully develop this family of integration methods. In addition, this family of integration methods can be either explicitly or implicitly implemented. Except for stability property, both explicit and implicit implementations have almost the same numerical properties. An explicit implementation is more computationally efficient than for an implicit implementation since it can combine unconditional stability and explicit formulation simultaneously. As a result, an explicit implementation is preferred over an implicit implementation. This family of integration methods can have the same numerical properties as those of the WBZ-α method for linear elastic systems. Besides, its stability and accuracy performance for solving nonlinear systems is also almost the same as those of the WBZ-α method. It is evident from numerical experiments that an explicit implementation of this family of integration methods can save many computational efforts when compared to conventional implicit methods, such as the WBZ-α method.

The purpose of this study was to investigate relations of resources and demands, family financial management and financial statement of urban households by applying a system approach. The results of this study were as follows; Saving rate had significant differences according to resources variables such as age, family life cycle, occupation of househead and housewife, ratio of employed to family member, and to demands variabels such as subjective prospect of business cycle, and value orientation, whereas total saving amount had significant differences according to resources vaiables such as age, family life cycle, educational level, percapita income, occupation of househead, type of income and to demand variable, perception of relative income. Also average monthly saving amount had significant differences according to resources vaiables such as educational level, per capita income, occupation of housewife, housing ownership, ratio of employed to family member, ratio of dependent to employed, and to demands variable, perception of relative income. The stocks had significant differences according to resources variables such as age, family life cycle, educational level, per capita income, occupation of househead, type of income, and housing ownership. Finally, real estate had significant differences according to resources variables such as age, family life cycle, educational level, percapita income, occupation of househead, type of income, housing ownership, and to demands variable, perception of relative income. Financial Statement among urban households according to family financial management had significant differences. And among all variables affecting financial statement among urban households, per capita income had the highest effect and perception of relative income was the second.

This study is to find effects between the level of preparation of factors and the satisfaction of successors. Independent variables are the level of preparations of successors and divided by three detailed type, the level of preparation of management ability, the level preparation of positive succession attitude and the level of preparation of ownership succession. A dependent variable is the satisfaction of successors and a moderating variable is the level of communication between successees and successors. This study was undertaken in South Korea among 59 successors in 59 family firms. A total of 53 samples were available to use for the research. The empirical results indicate that the level of preparation of successors, management ability, positive succession attitude and ownership succession, is associated to the satisfactions of successors. Additionally, the moderating variable has not the relationship to the dependent variable as a moderating variable, but the result showed a strong relationship between the level of communication and the satisfaction of successors.

The purpose of this study was to explore the dynamics of stepfamilies and the adjustment difficulties such families may experience. The study describes some sociodemographic characteristics of a sample of 117 stepfamilies. The independent variables were stresses due to adjustment difficulties, which were defined as "role strains". Sociodemographic variables included gender, family income level, length of time since remarriage, type of stepfamily, and the existence of any children born to the new marriage. The dependent variable was the extent of stepfamily adjustment, expressed as a scale. The factors influencing family adjustment included stepparent gender, family income level, type of stepfamily, and various role strain variables (family boundary ambiguity, role conflict, etc.). Practical recommendations for social work are made and possibilities for future research in this area are discussed based on the results of this study.

R-curve based on the size effect law previously developed for geometrically similar specimens (geometry type III) is extended to geometries with variable depth (geometry type I) as well as with variable notch (geometry type II), where the R-curve is defined as the envelope of the family of critical strain energy release rates from specimens of different sizes. The results show that the extended R-curve for type I tends to be the same for different specimen configurations, while it is greatly dependent on specimen geometry in terms of the initial crack length. Furthermore, the predicted load-deflection responses from the suggested R-curve are found to agree well with the testing results on concrete and rock materials. Besides, maximum loads for type II specimen are predicted well from the extended R-curve.

Acidovorax citrulli (Ac) is a phytopathogenic bacterium that causes bacterial fruit blotch (BFB) in cucurbit crops, including watermelon. However, there are no effective methods to control this disease. YggS family pyridoxal phosphate-dependent enzyme acts as a coenzyme in all transamination reactions, but its function in Ac is poorly understood. Therefore, this study uses proteomic and phenotypic analyses to characterize the functions. The Ac strain lacking the YggS family pyridoxal phosphate-dependent enzyme, AcΔyppAc(EV), virulence was wholly eradicated in geminated seed inoculation and leaf infiltration. AcΔyppAc(EV) propagation was inhibited when exposed to L-homoserine but not pyridoxine. Wild-type and mutant growth were comparable in the liquid media but not in the solid media in the minimal condition. The comparative proteomic analysis revealed that YppAc is primarily involved in cell motility and wall/membrane/envelop biogenesis. In addition, AcΔyppAc(EV) reduced biofilm formation and twitching halo production, indicating that YppAc is involved in various cellular mechanisms and possesses pleiotropic effects. Therefore, this identified protein is a potential target for developing an efficient anti-virulence reagent to control BFB.
