Purpose: The purpose of this descriptive study was to compare ways of coping and physical symptoms of realistic optimist with unrealistic optimist in university students. Methods: The participants for this study were students from three university, located in Seoul and Gangwon province. The data were collected by a questionnaire given to the students. Results: The most frequently used coping skills of realistic/unrealistic optimist was the pursuit of social support. Realistic optimists are likely to use not only active coping skills but also passive coping skills, on the other hand unrealistic optimists tend to less use all coping skills. But in physical health, it doesn't show a significant differences except gastro-intestinal symptoms between two group. Conclusion: Based on the finding of this study, it is needed nursing intervention for strengthening realistic optimism for helping university students cope with stress and health.

The present study aims to explore career maturity and influencing factors among elementary schoolers from poor families in Korea. Data are from 249 welfare recipient children in 10 administrative districts of Incheon. Scores of the work attitudes subdomain was lower than other aspects of career maturity including planning, self-appraisal, and independence in career decision-making. In the full sample, those in the higher academic years showed greater career maturity, planning, and self-appraisal, and those with greater parent attachment showed higher levels of self-appraisal. In separate analyses by gender, parent attachment showed greater influence on girls' career maturity. Finding from the separate analyses on lower vs. higher academic years (i.e. grades) revealed that parent attachment and female were associated with career maturity among lower graders, while academic achievement was associated with career maturity, planning, and self-appraisal among those in higher graders. Findings lend support to parental involvement in career education. Poor children might have limited perceptions of career focused on satisfying economic necessities. Career education should pay attention in helping them expand perceptions of the values of career.

Purpose: The purpose of this study is to identify the effect of aroma inhalation on stress responses (physical symptoms, levels of anxiety, perceived stresses)of nursing students. Method: This study was a quasi-experimental research using anon-equivalent pre-post design and was conducted from June 1 to June 5, 2002. The subjects consisted of 77 junior nursing students who were divided into 39 experimental group members and 38 control group members. A pretest and Post-test were conducted to measure body symptoms, the level of anxiety, and the level of perceived stress. In the experimental group, aromas were given using an aroma lamp, lavender, peppermint, rosemary and Clary-Sage. In the control group, the treatment was not administered. Result: As a result of administering aroma inhalation to nursing students, their physical symptoms decreased, their anxiety scores were low, and their perceived stress scores were low, showing that aroma inhalation could be a very effective stress management method. Conclusion: Nursing educators should play an important role in contributing to college students' physical and psychological health by helping enhance their recognition of stress management and effectively relieving their stress using essential oils.

Purpose: The purpose of this study was to describe the experience process of adolescents with hematologic malignancies. The question for the study was "What is the experience of adolescents with hematologic malignancies like?" Methods: The grounded theory methodology was used for this study. The data were collected through in-depth interview from 10 adolescents with hematologic malignancies. Data collection was done from January to June 2007. Theoretical sampling was used until the data reached saturation. Results: As a result of the analysis, "Reconstructing self-image from deviated and suspended life" was identified as the core category. And 11 subcategories were identified and they were integrated to the core category. 'Establishment of expanded and matured self' was identified as the consequence. Conclusion: The results of the study provide a frame for effective individualized nursing intervention strategies in helping adjustment of the adolescents with hematologic malignancies.

In the rapidly changing business environment, companies are introducing information technology to effectively manage internal resources in order to achieve a sustainable competitive advantage. We presented the Enterprise Social Network Service(SNS) as new information technology. Enterprise SNS provided employers with sociable functions like Facebook while supporting general task such as mail, authorization and notice. In this research, we focused on Enterprise SNS and suggested self-disclosure, enjoyment in helping others, perceived organizational support, generativity capacity as antecedent variables of Enterprise SNS usage. In addition, we verified the effect of the mediating role of generativity capacity between Enterprise SNS usage and job performance. For empirically verifying the proposed model, we collected sample data from 225 workers using Enterprise SNS and conducted analysis using a structural equation modeling. We expect that this study provides managers who are interested in introducing enterprise SNS with insights on how to facilitate enterprise SNS usage. Also, this study suggests useful theoretical implications to researchers who are interested in the use of enterprise SNS from the context of knowledge management.

In this article, the concept of gradient thickness is further extended to characterize the gradient behavior of the thermal and momentum boundary layer near a solid surface. The gradient thickness can replace the use of the conventional of the Nusselt and Reynolds numbers in terms of the gradient thickness provides a much easier grasp of the physical and practical meaning of the processes involved. Although there is no urgent need to discard the concept of the conventional convective heat transfer coefficient, the concept of the gradient thickness is believed to serve an efficient tool in helping students understand physics.

The paper presents two novel concepts of increasing the energy storage capacity at pumped storage power plants, both existing and new projects. The concepts utilize compressed air as a working medium to displace water from a volume originally not available for storage. The concepts are likely to give additional storage volume at a low cost, however, much development and many investigations are needed before the concepts can be shown to be technical and economical feasible solutions for energy storage. The concepts are disclosed so that researchers and utilities can start those investigations, hopefully helping the green transition by providing highly valuable energy storage for a future renewable energy having a much higher share of renewable energies than the current systems.

Nowadays, manufacturing system is trending toward integrated circumstance by helping of CAD/CAM/CAT. To use this system effectively, it is necessary to get exact 3 dimensional surface data of an object. We have been using contact method to measure 3 dimensional object profile. But his method has demerit of leaving scrach or small distortion on the object. To improve this, a non-contact measuring method using optical system is adopted. In this paper, We propose optical ring method. Withthis system, We could measure displacement of the object in the range of 45mm having 150mm having 150 .mu. m resolution with no scratch or distortion.
