  • Resourcefulness was analyzed by Walker and Avant's method to make a theoretical framework for nursing. Also, the appropriate Korean terminology was identified.“Resourcefulness”means the ability to use internal and external resources to eliminate or to control stress. '자원동원성' is chosen to be the most appropriate term to reflect the concept of resourcefulness. Upon the concept analysis, availability, controllability, confidence, and self-instruction were identified as the defining characteristics of resourcefulness. Contrary to other work, "availability" means the ability to use the social resources as well as the internal cognitive-behavioral resources. “Controllability” means the ability to delay or control immediate gratification of one's needs or to divert one's own mood in order to solve problem. "Confidence" is the self-efficacy belief in one's control ability. "Self-instruction" is the cognitive ability to instruct oneself positively. Resourcefulness is learned by active experience, vicarious experience, and formal or informal instruction, and it is cued in the presence of a stressful situation or a need for change. As a result of the use of resourcefulness, the target behavior performed immediately and ultimately improve the quality of life or adaptation. Therefore, it is necessary to develop the instrument including the defining attributes identified in this study. Also, it is necessary to simultaneously analyze the related concepts of self-efficacy, self-control, and self-regulation for appropriate use.

  • This paper deals with the vibration and stability of a circular cylindrical shaft, modeled as a tapered thin-walled composite beam and spinning with constant angular speed about its longitudinal axis, and subjected to an axial compressive force. Hamilton's principle and the assumed mode method are employed to derive the governing equations of motion. The resulting eigenvalue problem is analyzed, and the stability boundaries are presented for selected taper ratios and axial compressive force combinations. Taking into account the directionality property of fiber reinforced composite materials, it is shown that for a shaft featuring flapwise-chordwise-bending coupling, a dramatic enhancement of both the vibration and stability behavior can be reached. It is found that by the structural tailoring and tapering, bending natural frequencies, stiffness and stability region can be significantly increased over those of uniform shafts made of the same material. In addition, the particular case of a classical beam with internal damping effect is also included.

  • Thermal stability of quasi-isotropic composite and polymeric structures is considered one of the most important criteria in predicting life span of building structures. The outdoor applications of these structures have raised some legitimate concerns about their durability including moisture resistance and thermal stability. Exposure of such quasi-isotropic composite/polymeric structures to various and severe climatic conditions such as heat flux and frigid climate would change the material behavior and thermal viability and may lead to the degradation of material properties and building durability. This paper presents an analytical model for the generalized problem. This model accommodates the non-linearity and the non-homogeneity of the internal heat generated within the structure and the changes, modification to the material constants, and the structural size. The paper also investigates the effect of the incorporation of the temperature and/or material constant sensitive internal heat generation with four encountered climatic conditions on thermal stability of infinite cylindrical quasi-isotropic composite/polymeric structures. This can eventually result in the failure of such structures. Detailed critical analyses for four case studies which consider the population of the internal heat generation, cylindrical size, material constants, and four different climatic conditions are carried out. For each case of the proposed boundary conditions, the critical thermal stability parameter is determined. The results of this paper indicate that the thermal stability parameter is critically dependent on the cylinder size, material constants/selection, the convective heat transfer coefficient, subjected heat flux and other constants accrued from the structure environment.

  • Opioid aberrant behavior is an emerging problem as strong opioid is increasingly used to alleviate cancer pain in patients with cancer. Although the treatment of opioid addiction and physical dependence for non-cancer pain is well known, few studies have been conducted with cancer patients, particularly in the Korean population. Presented here are ten cases of cancer patients who were physically dependent on strong opioid and successfully treated with a partial mu-opioid receptor agonist, buprenorphine. This is the first report showing the efficacy of transdermal buprenorphine as a treatment for physical dependence on opioid medication in cancer patients.

  • The Environmental problem solving model is an instructional strategy to accomplish the aim of environmental education through investigation of environmental problems and issues of the community. This study is intended to compare the instructional effect of the structured model with the unstructured model of environmental problem solving. The experimental group received the structured instruction and the control group received the unstructured instruction. There did not appear to be any significant difference between the groups in regard to knowledge but in regard to knowledge of environmental issues, the experimental group was more effective than the control group. No significant differences existed between the groups in attitude. In regard to investigating skill and evaluation of environmental issues, the experimental group was significantly more effective than the control group. The experimental group was significantly more effective than the control group in regard to environmental action skills. To foster responsible environmental behavior, environmental education a number of methodologies must be considered and learners must be trained to become problem-solving citizens. It was noted that the structured instruction was more effective than the unstructured instruction in middle school where environmental issues were not taught as an independent subject. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its goals and the characteristics of the various learners. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its internal goals and the situations within which various types of learners explore environmental issues and solutions.

  • The hollow RC(Reinforced concrete) pier has the merit of lightweight pier compared with solid RC pier. However, the hollow RC pier shows a low ductile behavior due to brittle failure of inside concrete. To overcome this problem, the internally confined hollow reinforced concrete column has been developed. In this study, the behavior of internally confined hollow RC piers were evaluated with safety ratio, ductility, total material cost, the total weight of the pier, etc. The chosen parameters for the study are hollow ratio, thickness of internal steel tube, intervals between vertical re-bars, numbers of horizontal re-bars, and strength of concrete. As a result of parameters study, the usage of a minimum necessary thickness of the internal steel tube is the most effective.

  • Purpose: In this study differences in behavioral problems between children at risk for Attention Deficit Hyperactive Disorder (ADHD) and normally developing children were identified. Further, relationships between parental stress, depression, and child behavioral problems according to ADHD symptoms were explored. Methods: Participants were 222 elementary school children and their parents. The ADHD risk group was determined by the Korean-ADHD Rating Scale. Data were collected using the Korean-ADHD Rating Scale, Korean version of Child Behavior CheckList (K-CBCL), Parenting Stress Index, and Beck Depression Inventory. Data were analyzed using t-test, Pearson correlation coefficients, and regression analysis. Results: 1) The ADHD risk group showed higher levels of behavioral problems, parenting stress, and maternal depression than the normal group. 2) There were significant relationships between ADHD scores and parenting stress (r=.66), maternal depression (r=.35), internal behavioral problems (r=.47), and external problems (r=.55), but, ADHD risk scores were negatively correlated with social competence (r=-.40). 3) The regression analysis revealed that ADHD levels affected the child's internal behavioral problems, mediated by maternal depression ($\beta$=.29, p<.001). Conclusion: The study results show that higher risk scores for ADHD indicate a significant effect for behavioral problems. Also, parenting stress and depression influence child's behavioral problems. These results suggest that identification of children at risk for ADHD and development of parental education programs would contribute to the prevention of behavioral problems and aggravation of the ADHD symptoms.

  • This study is to suggest a new method of analyzing personality types of characters in narrative. First, we examined the history of the taxonomy of character types that existed in narrative theories so far. Until now, the classification of character types in narrative theory consisted largely of a formal classification based on roles in narrative, a content classification based on human internal qualities, and a complementary classification in which the two classification criteria are united. The problem with the existing character classification type is difficult to categorize it in spite of the usefulness of the content classification based on human internal qualities. On the other hand, the classification based on the role of the character in the narrative does not help as much as a practical analysis methodology because the classification is formal. In this study, we try to solve this problem by introducing Shalom Schwartz's human value type, and to make human character's value type and human role correlated with each other as a new character analysis methodology. Schwartz's study of value type is a very effective method to grasp the motivation of human behavior, and it seems to be very meaningful in analyzing the directivity of characters.

  • Fatigue is a process of progressive permanent internal structural change in a material subjected to repeitive stresses. These change may be damaging and result in progressive growth of cracks and complete fracture if the stress repetitins are sufficiently large. For structural members subjected to cyclic loads, the continuous and irrecoverable damage processes are taking place. These processes are referred as the cumulative damage processes due to fatigue loading. Moreover, increased use of high strength concrete makes the fatigue problem more important because the cross-section and dead weight are reduced by using high strength concrete. The purpose of this study is to investigate the shear fatigue behavior of reinforced concrete beams according to shear reinforcement ratio and concrete compressive strength under repeated loadings. For this purpose, comprehensive static and fatigue tests of reinforced concrete beams were conducted. The major test variables for the fatigue teats are the concrete strength and the amount of shear reinforcements. The increase of deflections and steel strains according to load repetition has been plotted and analyzed to explore the damage accumulation phenomena of reinforced concrete beams. An analytical model for shear fatigue behavior has been introduced to analyze the damage accumulation under fatigue loads. The failure mode and fatigue lives have been also studied in the present study. The comparisons between analytical results and experimental data show good correlation.

  • This paper addresses the systematic procedure using sequential approach for the analysis of the coupled thermo-mechanical behavior of a steady rolling tire. Not only the knowledge of mechanical stresses but also of the temperature loading in a rolling tire are very important because material damage and material properties are significantly affected by the temperature. In general, the thermo-mechanical behavior of a pneumatic tire is highly complex transient phenomenon that requires the solution of a dynamic nonlinear coupled themoviscoelasticity problem with heat source resulting from internal dissipation and friction. In this paper, a sequential approach, with effective calculation schemes, to modeling this system is presented in order to predict the temperature distribution with reasonable sccuracies in a steady state rolling tire. This approach has the three major analysis modules-deformation, dissipation, and thermal modules. In the dissipation module, an analytic method for the calculation of the heat source in a rolling tire is established using viscoelastic theory. For the verification of the calculated temperature profiles and rolling resistance at different velocities, they were compared with the measured ones.
