This study examined to find out mediating variable between ordinary stress and anxiety-depression. The subjects were 2,844 4th grade elementary school in Korea. The instruments used were questionnaires about anxiety-depression, ordinary stress, anger control ability and negative self-concept. Data were analyzed by t-test and regression. Major findings were as follows: (1) There were significant difference in parent-, appearance-, possession-related stress, anger control ability, negative self-concept and anxiety-depression according to sex. (2) Parent-, schoolwork-, peer-, appearance-related stress and anger control ability had a significant effect on the anxiety-depression. The principal finding was that anger control ability had mediating role between ordinary stress(schoolwork-, peer-, appearance-related stress) and anxiety-depression in male, one side parent-related stress and anxiety-depression in female. (3) Parent-, schoolwork-, peer-, appearance-related stress and negative self-concept had a significant effect on the anxiety-depression. The principal finding was that negative self-concept had mediating role between ordinary stress(parent-, schoolwork-, peer-, appearance-, possession-related stress) and anxiety-depression in male, one side parent-, peer-related stress and anxiety-depression in female.

The purpose of this study was to compare parenting stress between mothers who have young children with and without disabilities. The subjects of this study were 100 mothers who take care of disabled children and 123 mothers who take care of non-disabled children. The children's ages were from 3 to 6 years. The results of this study were as follows; First, the mothers who have disabled children have more parenting stress than those who have ordinary children. Second, the mothers who have developmentally disabled children had more parenting stress than mothers who had other disabled children. Children's and mothers' ages had an influence on the parenting stress of the ordinary mothers. The mothers who had children with and without disabilities got less parenting stress as the mothers received more higher parenting efficacy, parent role satisfaction, marital satisfaction and family support.

Two-dimensional tensile stresses are occurring at the back of the anchorage of the tendons of prestressed concrete bridges. A new method named "tensile stress region" for the design of the reinforcement is presented in this paper. The basic idea of this approach is the division of an anchor block into several slices, which are described by the tensile stress region. The orthogonal reinforcing wire mesh can be designed in each slice to resist the tensile stresses. Additionally the sum of the depth of every slice defined by the tensile stress region is used to control the required length of the longitudinal reinforcement bars. An example for the reinforcement design of an anchorage block of an external prestressed concrete bridge is analyzed by means of the new presented method and a finite element model is established to compare the results. Furthermore the influence of the transverse and vertical prestressing on the ordinary reinforcement design is taken into account. The results show that the amount of reinforcement bars at the anchorage block is influenced by the layout of the transverse and the vertical prestressing tendons. Using the "tensile stress region" method, the ordinary reinforcement bars can be designed more precisely compared to the design codes, and arranged according to the stress state in every slice.

This study compared parental satisfaction between mothers who have young children with and without disabilities. The study subjects were 100 mothers who take care of disabled children and 123 mothers who take care of non-disabled children. The children's ages were from 3 to 6 years. The results of this study were as follows First, the mothers who take care of disabled children had lower mother's parental satisfaction than those who have ordinary mothers. Second, the children's age and the degree of disability had an affirmative influence on the parental satisfaction of the mothers who have disabled children. There were significant differences in the parental satisfaction of the mothers who have ordinary children according to mothers' age and their educational background. The parental satisfaction in both mother groups increased with increasing parenting efficacy, marital satisfaction and family support, and with decreasing parenting stress. Finally, parenting efficacy, children's age, parenting stress, and family support significantly predicted the parental satisfaction of the mothers who have disabled children while parenting efficacy, parenting stress, and educational background significantly predicted the parental satisfaction of the mothers who have ordinary children.

This paper is to examine the applicability of ordinary Kriging interpolation(OK) to the p-adaptivity of the finite element analysis that is based on variogram. In the p-refinement, the analytical domain has to be refined automatically to obtain an acceptable level of accuracy by increasing the p-level non-uniformly or selectively. In case of non-uniform p-distribution, the continuity between elements with different polynomial orders is achieved by assigning zero higher-order derivatives associated with the edge in common with the lower-order derivatives. It is demonstrated that the validity of the proposed approach by analyzing results for stress singularity problem.

In order to prevent bodily injuries frequently suffered in using bush cutters, especially from spattered stones, we developed a unique new cutting system equipped with a fixed blade on top of the rotary blade, and checked into the mowing performance of the cutter. From experimental test of mowing efficiency and measuring test of physical stress (O$_2$ consumption and heartbeat rates) , the new cutting system with a fixed blade proved that it keeps good cutting performance with lower peripheral speed of the rotary blade(22m/sec), compared to that of ordinary cutting blade, yielding more safety in operation. Weight of the cutter head is, however, heavier than that of ordinary machine by about 70% which increased a physical stress on the operator with slightly faster heartbeat rates. In mowing along edge of concrete wall, the operator enjoyed using the cutter with no anxiety , owing to function of the fixed blade.

The purpose of this paper is to explore the relationship between the number of relocation and volition of soldier's service based on system thinking perspective using a causal loop analysis. Research adopting system dynamics concerning on the volition of soldier's service and relocation has not been studied yet. Causal loops are analyzed and evaluated by focusing on soldier's military performance, stress of family members and family members' welfare service. Result of this study is that soldier's periodical movement is indispensable factor maintaining military life. Most of the married soldier's life conditions are worse than ordinary people. As the number of relocation is increasing family of soldier's stress is increased by anxiety for welfare conditions is supposed to relocate. The number of movement to another place of soldier's children is more than two times and the result of learning achievement is worse than ordinary students. This kind of stress can influence the married soldier's military performance and stress. So the welfare service should be expanded to an official residence, education, facility, district network service and so on.

This study aims to show the change of Heart Rate Variability(HRV) and Pulse wave velocity(PWV) on menstruation in women at college. Heart Rate Variability(HRV) and Pulse wave velocity(PWV) of 122 women at college were measured at their menstruation and ordinary period. SDNN, RMSSD, SDSD, HRV Index(%), stress resistance and cardiac activity were significantly higher at their menstruation than ordinary period, but Total Power and pNN50(%) were opposite. The automatic nervous system balance and physical stress were decreased in groups without dysmenorrhea than with one. PWV(E-R) and PWV(E-L) were much higher at menstruation than ordinary period. PTT(F-R) and PTT(F-L) were decreased in groups without dysmenorrhea than with severe one. We demonstrated that menstruation can effect on Heart Rate Variability and Pulse wave velocity and dysmenorrhea can cause the imbalance of autonomic nervous system.
