많은 사람들이 썬탠을 즐기며 건강해 보일것이라고 생각한다. 하지만 태양 광선을 많이 쬐면 건강에 해롭다는 것에 관심이 모아지고 있다. 태양 광선은 자외선 영역 안에서 어느정도 약간 포함되어 있는 파장을 가진 빛을 많이 포함하며 자외선을 과도하게 흡수하면 화상을 가져올 수 있기 때문에 주의를 요해야 한다.

We conducted laboratory simulations of deep vertical drilling into the earth's crust to induce borehole breakouts and investigated their potential use for estimating in situ stress magnitudes in Westerly granite and Berea sandstone. Our experiments consisted of two major stages, a series of triaxial tests and borehole-breakout formation tests under a wide range of far-field stresses. We derived the Mohr-Coulomb, Nadai and Mogi failure criteria from the triaxial test results. Each criterion was compared with the stress condition at breakout boundaries. We concluded that the well known Mohr-Coulomb criterion is not compatible with the stress condition at breakout failure. On the other hand, polyaxial (truly triaxial) failure criteria such as the Nadai criterion for Berea sandstone and the Mogi criterion for Westerly granite were much more suitable for predicting breakout failure zone. Such failure criteria appeared to enable the reliable estimation of the magnitude of one of two horizontal principal stresses if the other one is known.

As the scale of airborne system software increases, the use of OOT (Object-Oriented Technology) is increasing for functional expansion, efficient development, and code reuse, but the verification method for airborne object-oriented software is conducted from the perspective of the existing procedure-oriented program. The purpose of this paper was to analyze the characteristics of OOT and the vulnerabilities derived from the functional characteristics of OOT, and present a verification method applicable to each software development process (Design, Coding and Testing) to ensure the functional safety integrity of aviation software to which OOT is applied. Additionally, we analyzed the meaning of the static analysis results among the step-by-step verification measures proposed by applying LDRA, a static analysis automation tool, to PX4, an open source used to implement flight control software.

The purpose of this study was to provide information necessary to strengthen maternal role adaptation of employed mothers by identifying factors affecting maternal role adaptation of employed mothers with young children. The subjects of this study were convenience extracts from 137 employed mothers with infants under 24 months of residence in H city, Gyeonggi-do. Data were processed using descriptive statistics, t-test, ANOVA, correlation analysis, and stepwise regression analysis. As a result of the study, maternal role adaptation was positively correlated with mother attachment(r=.488, p<.001) and social support(r=.718, p<.001). Social support(β=.616), baby status at birth(β=.123), current breastfeeding status(β=.127) and maternal attachment degree(β=.141) affect the maternal role adaptation of employed mothers. The explanatory power of regression analysis was 55.5%(F=43.487, p<.001). As a result of the study, social support was found to be the most important factor influencing maternal role adaptation of employed mothers. Various intervention strategies for promoting social support in families, workplaces and communities are required for maternal role adaptation to employed mothers.

Purpose: The purpose of this study was to examine relationship of preschool child and mother interaction, child's health status, health-related quality of life and social development. Also, it was intended to provide a basis for development of mother-child interaction programs. Methods: The present study was a descriptive research. Participants in this study were a convenience sample of 230 preschool children and their mothers. For the final analysis 209 questionnaires were used after eliminating questionnaires with incomplete responses. Data were analyzed using the SPSS 18.0 program. Results: The mean score for interaction between preschool child and mother was $3.96{\pm}0.55$ out of 5 points, for child health status, $3.75{\pm}0.62$ out of 5 points, for child's health-related quality of life, $83.89{\pm}10.20$ out of 100 points and for child's social development, $19.66{\pm}3.57$ out of 24 points. Positive correlations were found between interaction of preschool child and mother, child's health status, health-related quality of life, and social development. Conclusion: The results demonstrate the importance of the quality of the relationship between mother, the child's primary caregiver, and her child for the healthy growth and development of preschool children. It is suggested that intervention programs for preschool child-mother interaction should be developed using evidence based data.
