Purpose: The purpose of this study was to identify attributes of the concept of cancer survivorship. Methods: Walker & Avant's concept analysis framework (2005) was used to review the medical & nursing text books, medical and nursing research articles related to cancer survivorship and published from 1985 to 2011. Results: There were nine aspects of the concept of cancer survivorship: A process, liminality, uncertainty, life-changing experience, complexity, unique experience, duality of positive and negative aspects, partnership, and need for support. Antecedents of cancer survivorship were cancer diagnosis and perception as a cancer survivor. Empirical referents of cancer survivorship were survival rate, quality of life, adaptation to the survivorship experience, and health-related hardiness, social support, spirituality, and health behavior. The consequences of cancer survivorship were effects on the physical, psychosocial, spiritual and socio-economic well-being of the patients. Conclusion: This concept analysis of cancer survivorship is expected to contribute to promotion of survivorship care in the clinical field by removing conceptual ambiguity and confirming the true meaning of survivorship care.

Purpose: The purpose of this article was to review and discuss the current status, issues, and nursing perspectives of cancer survivorship. Methods: A comprehensive literature review was conducted. Results: The major areas of concern for the survivors included recurrence, secondary malignancies, and long-term treatment sequalae which affect their quality of life. The four essential components of survivorship are prevention, surveillance, intervention, and coordination. Cancer survivorship care plan should address survivor's long-term care, such as types of cancer, treatment modalities, potential side effects, and recommendations for follow-up. It also needs to include preventive practices, health maintenance and well-being, information on legal protections regarding employment and health insurance, as well as psychosocial services in the community. Survivorship care for cancer patients requires multidisciplinary efforts and team approach. Conclusion: Nurses are uniquely positioned to play a key role in ensuring quality services for cancer survivors and family members. Nurses should review the care plans for cancer survivorship with patients and families by instructing them when to seek medical treatment, promoting any recommended surveillance protocols, and encouraging healthy life styles for health promotion and quality of life.

Objectives: To examine survivorship disparities in demographic factors and risk status for non-muscle-invasive bladder cancer (NMIBC), which accounts for more than 75% of all urinary bladder cancers, but is highly curable with early identification and treatment. Methods: We used the US National Cancer Institute's Surveillance, Epidemiology, and End Results registries over a 19-year period (1988-2006) to examine survivorship disparities in age, sex, race/ethnicity, and marital status of patients and risk status classified by histologic grade, stage, size of tumor, and number of multiple primary tumors among NMIBC patients (n=29 326). We applied Kaplan-Meier (K-M) and Cox proportional hazard methods for survival analysis. Results: Among all urinary bladder cancer patients, the majority of NMIBCs were in male (74.1%), non-Latino white (86.7%), married (67.8%), and low-risk (37.6%) to intermediate-risk (44.8%) patients. The mean age was 68 years. Survivorship (in median life years) was highest for non-Latino white (5.4 years), married (5.4 years), and low-risk (5.7 years) patients (K-M analysis, p<0.001). We found significantly lower survivorship for elderly, male (female hazard ratio [HR], 0.96), Latino (HR, 1.20), and unmarried (married HR, 0.93) patients. Conclusions: Survivorship disparities were ubiquitous across age, sex, race/ethnicity, and marital status groups. Non-white, unmarried, and elderly patients had significantly shorter survivorship. The implications of these findings include the need for a heightened focus on health policy and more organized efforts to improve access to care in order to increase the chances of survival for all patients.

Wintering migratory species of white-fronted geese (Anser albifrons) are common visitor in South Korea, and this study examined the survivorship of white-fronted geese in the Junam Reservoir with the application of Population Viability Analysis (PVA) technique. In Junam PVA analysis was done for the next 50 years using factors of breeding population, sex ratios, survivorship in the VORTEX program. As a result white-fronted geese will reach to carrying capacity within 40 years, and population will reach to carrying capacity later when it becomes smaller. Also with a large initial population white-fronted geese will reach to carrying capacity earlier. In conclusion, for the next 50 years the white-fronted geese are expected to a long-term survival with stable condition with survivorship (0.03) and extinction rate (0.0).

Population ecological characteristics of growth and mortality play an important role in understanding the population dynamics of marine mammals. The instantaneous coefficients of natural and bycatch mortality were estimated for minke whales (Balaenoptera acutorostrata) in Korean waters using a population assessment model composed of bycatch and abundance data. The survivorship curve of this population was fitted to the data, and then the curve was revised using age-specific relative bycatchability coefficients ($q_t$). Instantaneous coefficients of natural and bycatch mortality of minke whales were estimated as 0.024/year and 0.076/year, respectively, and from this the survival rate was estimated as 0.905. This estimated survival rate was comparable to other cetaceans in other regions. The $q_t$ for this population ranged from 0.020 to 0.193. The revised survival rates were higher when the $q_t$ was taken into account. The mortality coefficient, survival rate, $q_t$ and survivorship curves had not previously been determined for minke whale in this area. This estimate could serve as fundamental information to assess the status of this population and for conservation and rational management.

Background: In this study, we proposed that the population dynamics of non-native red-eared sliders (Trachemys scripta elegans) depends on the species' habitat extension and survivorship. We used a logistic equation with time-dependent habitat carrying capacity. In detail, the present carrying capacity depends on the red-eared slider population of the previous year. Anthropogenic activities such as the abandonment of previously captive red-eared sliders or the release due to religion customs would supply new habitats to the species. Therefore we assumed that anthropogenic spread increases the habitat carrying capacity. Based on the urbanization increase rate of 3% in Korea from 1980 to 2000, we assumed an annual spread of 3% to simulate the population dynamics of the red-eared slider. In addition, the effect on the population of an increase of natural habitats due to migration was simulated. Results: The close relationship between the distributions of non-native red-eared sliders and of urbanized areas demonstrates that urbanization plays an important role in providing new habitats for released individuals. Depending on the survivorship, the population of the red-eared slider in Korea increased 1.826 to 3.577 times between 1980 and 2000. To control population growth, it is necessary to reduce carrying capacity by reducing habitat expansion through prohibition of release into the wild ecosystem and careful managements of the wetland or artificial ponds. Changes in the habitat carrying capacity showed that the population fluctuated every other year. However, after several years, it converged to a consistent value which depended on the survivorship. Further, our results showed that if red-eared sliders expand their habitat by natural migration, their population can increase to a greater number than when they have a 99% survivorship in a fixed habitat. Conclusions: Further introductions of red-eared sliders into wetlands or artificial ponds should be prohibited and managed to prevent future spread of the species. Moreover, it is important to reduce the species' survivorship by restoring disturbed ecosystems and maintaining healthy ecosystems.

Purpose: The purpose of this study was to compare health promotion behavior, post-traumatic growth and quality of life according to the stages of survivorship in patients with female genital neoplasm. Methods: Data were collected from August 1st, 2011 to September 31st 2011 from 142 gynecologic cancer patients who completed treatment or were treated at an out-patient clinic. The instrument were HPLP developed by Walker, Sechrist & Pender, PTGI developed by Tedeschi & Calhoun, and Korean C-QOL. Results: Health promotion behavior scores were significantly higher in the acute survival stage than the extended survival stage. Post-traumatic growth score was higher in the acute survival stage than the extended survival stage. The quality of life scores were higher in the lasting survival stage than the extended survival stage. Conclusion: Gynecological cancer patients in the extended survival stage reported low scores of health promotion behavior, post-traumatic growth and quality of life. Intervention needed to be developed to improve health promotion behavior, post-traumatic growth and quality of life for patients with female genital neoplasm in the extended survival stage.

Habitat heterogeneity can enhance biological diversity by providing variation in structural diversity. This paper reviewed heterogeneous habitat serves as a population stability and superior demographic performance (e.g., high density, survivorship, reproductive rate) can be observed compared with organisms with inferior demographic performance. The idea of habitat variation has been further developed in modelling. Furthermore the size and configuration (distribution) of a patch (of a particular habitat type) become effective for the stability of population through hiding places and food resources. Species diversity is related to habitat complexity that provides structural diversity to ground -dwelling organisms. Finally coarse woody debris can enhance habitat complexity thus stabilizing population fluctuation and increasing survivorship.
