Caring for patients with cancer is highly stimulating and rewarding, attracting health professionals to the field who enjoy the challenge of managing a complex illness. Health professionals often form close bonds with their patients as they confront ongoing disease or treatment impacts, which may be associated with multiple losses involving function and/or eventual loss of life. Ongoing exposure to patient loss, along with a challenging work setting, may pose significant stress and impact health professionals' well-being. The prevalence rates of burnout and compassion fatigue (CF) are significant, yet health professionals have little knowledge on these topics. A 6-week continuing education program consisting of weekly small-group video-conferencing sessions, case-based learning, and an online community of practice was delivered to health care providers providing oncology care. Program content included personal, organization and team-related risk and protective factors associated with CF, grief models, and strategies to mitigate against CF. Content analysis was completed as part of the program evaluation. In total, 189 participants (93% nurses) completed the program, which was associated with significant improvements in confidence and knowledge of CF and strategies to support self and team resilience. Qualitative themes and vignettes from experiences with the program are presented. Key themes included knowledge gaps, a lack of support related to CF and strategies to support resilience, organization-and team-based factors that can inhibit expression about the impacts of clinical work, the health professional as a "person" in caregiving, and the role of personal variables, self-skill practices, and recommendations for education and support for self and teams.

Purpose: This survey was to investigate the differences in smartphone addiction symptoms by the level of addiction among college students in S. Korea. Methods: Two hundred and thirteen university students survey data was collected from December 5th to 9th of 2011 using Smartphone Addiction Scale. 25.3% (n=54) of total respondents were categorized as highly addicted and 28.17% (n=60) were as non-addicted group. Results: There were significant differences in total addiction symptom scores, daily life disorders, loss of self control, pathological concentration, and compulsive symptoms between two groups. There were significantly differences in total addiction symptoms, daily life disorders, loss of self control, pathological concentration, and compulsive symptoms between two groups. Highly addicted group were significantly higher in total addiction symptom scores (3.26 times), daily life disorders (4.96 times), loss of self control (3.07 times), pathological concentration (3.07 times), and compulsive symptoms (2.86 times) compared to non-addicted one. Highly addicted group had significantly higher daily usages of smartphone and were more satisfied with smartphone than non-addicted group. The purpose to use was related to academic works rather than games or entertainment. However satisfaction on academic achievement was very low. Conclusion: The smartphone addicted symptoms related to academic works were significantly high in highly addicted college students so that it disturbed their daily life and psycho-social health in general. It is clear that the highly addicted college students need urgent distinctive interventions such as creative academic guides.

Steel plate shear wall with self-centering energy dissipation braces (SPSW-SCEDB) is a lateral force-resisting system that exhibits flag-shaped hysteretic responses, which consists of two pre-pressed spring self-centering energy dissipation (PS-SCED) braces and a wall plate connected to horizontal boundary elements only. The present study conducted a series of cyclic tests to study the hysteretic performances of braces in SPSW-SCEDB and the effects of braces on the overall hysteretic characteristics of this system. The SPSW-SCEDB with PS-SCED braces only exhibits excellent self-centering capability and the energy loss caused by the large inclination angle of PS-SCED braces can be compensated by appropriately increasing the friction force. Under the combined effect of the two components, the SPSW-SCEDB exhibits a flag-shaped hysteretic response with large lateral resistance, good energy dissipation and self-centering capabilities. In addition, the wall plate is the primary energy dissipation component and the PS-SCED braces provide supplementary energy dissipation for system. The PS-SCED braces can provide up to 90% self-centering capability for the SPSW-SCEDB system. The compressive bearing capacity of the wall plate should be smaller than the horizontal remaining restoring force of the braces to achieve better self-centering effect of the system.

This paper presents the design of a small scale High Tc superconducting power transformer. In the design of the transformer, BSCCO-2223 tape was considered as the conductor. Double pan cake winding was adopted in order to easy the construction of the winding and to lessen the leakage reactance of the transformer. Numerical calculation was used to decide the arrangement of the double pan cake winding. Estimation of the AC loss, magnetizing loss and self field loss, in the superconducting winding and the iron loss in the core were given.

In this paper, we describe the analysis of interior noise for tilting train that is being developed in Korea. Tilting train is made of composite material to reduce the car body's weight and attached a self-steering system on bogie to improve curving performance. However, the acoustic performance (Transmission Loss) of such material is worse than the materials of conventional train, such as aluminum, steel and so on. Therefore, we measure the transmission loss of side wall/floor of tiling train and predict the interior noise for tilting train using its measuring results.

The ILI, developed by the IWA (International Water Association), has been used in many countries as an indicator of water leakage. In Korea, the revenue water has been used as a performance indicator for waterworks although there is an opinion to replace it with the ILI. Hence, it has been necessary to investigate whether the ILI can replace the revenue water in Korea. The four main operating indicators (i.e., water service population, profit-loss ratio, fiscal self-reliance, and aged pipe rate) of 162 Korean waterworks were compared with the ILI with the linear regression method. Local water authorities with more than 1 million water service population, with more than 60% profit-loss ratio, more than 40% and less than 60% fiscal self-reliance, and more than 20% aged pipe rate showed meaningful correlation between the four parameters and the ILI. In the remaining cases, their correlations were little or weak. This means that using the ILI may not be an efficient method to represent the performance of the water supply system in Korea because of the lack of UARL (Unavoidable Annual Real Losses) data accuracy. To use the ILI in Korea, it will be required to carry out an additional research to accumulate reliable CARL (Current Annual Real Losses) and UARL data in the future.

Purpose: This descriptive study was designed to investigate Body Mass Index(BMI), weight control behavior, and self-esteem in high school adolescents. Method: The convenience sample consisted of 129 high school females and 106 high school males. Data were collected using a self-report questionnaire from November to December, 1999. BMI was calculated by using the subject's self-reported body weight and height to identify objective obesity. Self evaluation about subjective obesity was measured by a single item question. Preferred BMI was calculated by using the subject's elf-reported body weight and height which the subjects desired. The Rosenberg's Self-Esteem Scale was utilized to measure the level of self-esteem. Results: Results of the study revealed that high school females perceived themselves as more more obese than their the actual BMI, excessively participated in dieting behavior and exercises, and reported lower self-esteem than that of males. Conclusion: Based on this study, health care providers need to educate female adolescents about healthy behavior as well as the normal weight range in BMI.

The ratio of the elderly population is rapidly growing due to socio-economic development and better medical services. As the average life-span of the Korean elderly becomes longer, the proportion of the elderly is increasing. Therefore, the elderly need to sustain a high quality of life. However, all these factors, such as sensory loss, decreased endurance, mobility limitation, and a loss of independence, act to diminish the quality of life among the elderly. It is necessary for elders to adapt themselves to aging, to maintain their physical functions and especially, it is important to keep their independence in activity of daily living and self care. Therefore, this study was designed to identify the degree of activity in daily living and exercise of a self-care agency and to investigate the relationship between activity of daily living and self-care agency. Also, this research aimed to contribute to nursing interventions that maintain and promote quality of life of the elderly and to enable themselves to live independently. The subject of this study were 160 elders, over age 65, who were sampled in C city. Data were collected by observation and questionnaires from May,1999 to December, 1999. The measurement tools were Barthel Index(1979), Lawton & Brody(1969) for activity of daily living and Kearney & Fleischer(1979) for self-care agency. Data were analyzed by SAS PC+ package and included descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and Cronbach's alpha. The conclusions of this study are summarized as follows; 1. The mean of ADL and IADL was 96.09 and 16.38, respectively. The score described activity of daily living among the elders in C province as moderate. Particularly, in the items of IADL, the item of medication was the highest score. 2. The mean for exercise of self-care agency was 76.48, a moderate degree. 3. The degree of ADL and IADL according to demographic characteristics was significantly different statistically in pocket money, the presence of disease, perceived health status and in occupation, pocket money, family type, the presence of disease, and perceived health status, respectively. 4. The dagree of selt-care agency according to demographic characteristics was significantly different statistically in gender, education level, economic status, and pocket money. 5. There was a significant positive correlation between activity in daily living and self-care agency. Based on these results, further research is suggested to discover the variables influencing the activity of daily living and self-care agency to develop nursing strategies for improving self-care and activity of daily living among the elderly.

This paper presents the self-commissioning for surface-mounted permanent magnet synchronous motor. The proposed strategy executes three tests with a standard inverter drive system. To do this, synchronous d-q axes currents are appropriately controlled for each test. From the three tests, armature resistance, armature inductance, equivalent iron loss resistance, and emf coefficient are identified automatically. The validity of the proposed strategy is confirmed by experimental results.

The magnetization and self-field losses of the four technical high-T$_{c}$ superconducting tapes have been investigated experimentally. The results show that the magnetization losses for parallel or perpendicular fields can be well predicted from the slab model or the strip model for a filamentary region. However the magnetization losses for longitudinal fields can be rather predicted by the slab model for a decoupled filament. The self-field losses are well explained by the Norris ellipse model.l.
