Resistance to diseases caused by turnip mosaic virus (TuMV) in crop species of the family Brassicaceae has been studied extensively, especially in members of the genus Brassica. The variation in response observed on resistant and susceptible plants inoculated with different isolates of TuMV is due to a combination of the variation in the plant resistome and the variation in the virus genome. Here, we review the breadth of this variation, both at the level of variation in TuMV sequences, with one eye towards the phylogeny and evolution of the virus, and another eye towards the nature of the various responses observed in susceptible vs. different types of resistance responses. The analyses of the viral genomes allowed comparisons of pathotyped viruses on particular indicator hosts to produce clusters of host types, while the inclusion of phylogeny data and geographic location allowed the formation of the host/geographic cluster groups, the derivation of both of which are presented here. Various studies on resistance determination in particular brassica crops sometimes led to further genetic studies, in many cases to include the mapping of genes, and in some cases to the actual identification of the genes. In addition to summarizing the results from such studies done in brassica crops, as well as in radish and Arabidopsis (the latter as a potential source of candidate genes for brassica and radish), we also summarize work done using nonconventional approaches to obtaining resistance to TuMV.

Purpose: The purpose of this study was to understand the nurses' experiences of end of life care of older adults with dementia living in long-term care hospitals and geriatric care facilities. Methods: The participants were nine nurses. Open in-depth interviews were used to collect data from June, 2016 to November, 2016. Colaizzi's phenomenological approach was used to analyze the data. Results: Three categories were identified. The nurses' reported experiences of end of life care of older adults with dementia were 'warm care with living together', 'care for family', and the 'self-reflection and responsibility as a nurse'. There were ten clusters of themes and 24 themes. The participants stated that the end of life care of older adults with dementia were individualized holistic care with dignity, being in older adults with dementia and family, and responsibility as a professional. Nurses reported the need for dementia hospice care. Conclusion: These results could be considered in planning nursing intervention for hospice care. The findings support the need for educational strategies and programs to improve end of life care among older adults with dementia.

Purpose: The purpose of the study was to identify and describe illness experiences of men with myocardial infarction. Methods: Data were collected through individual in-depth interviews with 10 male patients. Analysis was done using phenomenological analysis. Results: Five theme clusters including 11 themes emerged. 1) "Unexpected grave disease instantly dividing life and death" describes the great ignorance of symptoms and experience as a survivor narrowly escaping death. 2) "A disease still not considered a disease" illustrates the paradoxical and confusing situation between low level of awareness of the severity of the disease and high level of reflection on their unhealthy lifestyles. 3) "Fighting against me for health" illustrates their resolution and action to maintain health while experiencing helplessness. 4) "Relationships in a no-win situation" contains defensive posture due to social stigma and the dilemma of family breadwinners. And 5) "Introspection of past and future life" describes positive turnings in life through enlightenment in addition to remorseful feeling about the past and persistent worry of death. Conclusion: Health professionals need to support men with myocardial infarction by providing family-oriented and empowerment-based self-management interventions to lead to success in their illness journey and to improve their quality of life.

Purpose: The purpose of this study was to further understanding of the experience in acceptance of hospice by patients with terminal cancer and to explore the structure of this experience. Methods: A phenomenological methodology was used for the study. Participants were nine patients who were admitted to the hospice unit of a university hospital. In-depth interviews were done for data collection and the data were analyzed using Colaizzi's method. Results: Four categories, eight theme clusters and 18 themes were identified for the experience in acceptance of hospice by patients with terminal cancer. The three categories were 'Hope for a comfortable death', 'Overcoming barrier of prejudice about hospice', 'Incessant craving for life', 'The last consideration for self and family' Conclusion: While accepting the hospice care, participants experienced inner conflict between giving up medical treatments that prolong life and choosing a comfortable death, and also experienced an incessant craving for life. By accepting hospice care, they showed a human dignity that entails careful concerns for both self and family members.

Exploring the risk factors of adolescent suicide is important for effective suicide prevention. This study explored the clustering of adolescent suicides based on six risk factors: mental disorder, broken family, depression, anxiety, previous suicide attempts, and deviant behaviors. Using 173 student suicide reports obtained from the Ministry of Education, we evaluated the associations between suicide and variables related to mental disorders; dysfunctional family life; depression and anxiety; previous suicide attempts; deviant behaviors such as drinking and smoking; and school life characteristics, including attendance and discipline, problems within the past year, and incidents prior to suicide. In addition, reports of warning signs just before suicide were included in the analysis. The two-stage cluster analysis classified the students into three clusters: the silent type (cluster 1; 48.55%), in which no risk factors were observed; environmental-risk type (cluster 2: 24.28%), which featured a high frequency of broken households, deviant behaviors such as smoking/drinking and running away from home; and depressive type (cluster 3: 27.17%), which featured a high frequency of mental health problems such as depression, anxiety, and suicide attempts. Identifying the sub-types of adolescent suicide may help to inform tailored suicide prevention and intervention strategies in school.

Purpose: This study was conducted in order to identify and describe the experiences of health care during pregnancy, birthing, and postpartum period for Vietnamese marriage immigrants. Methods: The participants were 15 Vietnamese married immigrant women who became pregnant and gave birth within the last five years. Data were collected by in-depth interview with Vietnamese women. Data were analyzed using Colaizzi's method of phenomenology. Results: Six theme clusters were extracted as follows: 'being left with no other option in loneliness and longing filled in a limited life', 'continued trials and errors amidst frustration and fear', 'silently following orders despite the quality of medical services that change with each medical care provider', 'compromise by selecting amidst confusion between the Korean way and the way at home', 'depending on family, who is the communication channel, but becoming disappointed', and 'finding the reason for existence and struggling by herself to become a mother amidst doubled confusion'. Conclusion: A program for effective empowerment of Vietnamese immigrant women should be developed. In addition multicultural family centered programs should be developed with emphasis on acceptance of women's culture, respect for her culture, and supports. Medical staffs and nurses should also improve culturally sensitive competence in order to provide care for immigrant women.

Purpose: The purpose of this study was to examine the life-sustaining treatment decisions of terminal cancer patients. Methods: Data on 10 terminal cancer patients who decided to withhold or withdraw from treatment were collected using in-depth interviews conducted from February 8 to October 30, 2019. Data were collected until saturation was reached and then analyzed using Colaizzi's phenomenological method. Results: In this study, six thematic clusters were identified: "having complicated feelings", "making choices to protect everyone", "accepting and preparing for death", "feeling distress", "pursuing spiritual wellbeing", and "evaluating the new system". Conclusion: When facing death, terminal cancer patients often made choices to protect their family and their dignity with uneasiness of mind when deciding to withdraw from life-sustaining treatments. Though many patients had accepted and prepared for death, they experienced distress about leaving children behind after death. They also pursued spiritual well-being to find peace after deciding to withdraw from life-sustaining treatment. In addition, participants evaluated the new system of policies pertaining to decisions on life-sustaining treatment. Thus, various approaches regarding acceptance and preparation for death, communication with family, hope, and spiritual comfort should be taken in educational interventions to assist terminal cancer patients as they decide whether to withdraw from life-sustaining treatment.
