PURPOSE: To propose a conceptual design of a novel source for intensity modulated brachytherapy. MATERIALS AND METHODS: The source design incorporates both radioactive and shielding materials (stainless steel or tungsten), to provide an asymmetric dose intensity in the azimuthal direction. The intensity modulated intravascular brachytherapy was performed by combining a series of dwell positions and times, distributed along the azimuthal coordinates. Two simple designs for the beta-emitting sources, with similar physical dimensions to a 90Sr/Y Novoste Beat-Cath source, were considered in the dosimetric feasibility study. In the first design, the radioactive and materials each occupy half of the cylinder and in the second, the radioactive material occupies only a quater of the cylinder. The radial and azimuthal dose distributions around each source were calculated using the MCNP Monte Carlo code. RESULTS: The preliminary hypothetical simulation and optimization results demonstrated the 87% difference between the maximum and minimum doses to the lumen wall, due to off-centering of the radiation source, could be reduced to less than 7% by optimizing the azimuthal dwell positions and times of the partially shielded intravascular brachytherapy sources. CONCLUSION: The novel brachytherapy source design, and conceptual source delivery system, proposed in this study show promising dosimetric characteristics for the realization of intensity modulated brachytherapy in intravascular treatment. Further development of this concept will center on building a delivery system that can precisely control the angular motion of a radiation source in a small-diameter catheter.

PURPOSE: The purpose of this study was to explore the lived experiences of homeless persons. METHODS: A phenomenological methodology was used for the study. Participants were people enrolled in the Center for homeless persons in Kyunggi Province and eligible for the study. Data were collected through in-depth interviews with nine participants between October 13 and November 16, 2016. Data analysis was conducted using Colaizzi's method. RESULTS: Five themes and twenty meanings were formulated for experiences of homeless persons. The five themes were ‘Abandoning their life’, ‘Being familiar with a free homeless life’, ‘Being isolated from the world’, ‘Being impoverished’, ‘Desire to break away from the life of homelessness’. CONCLUSION: The study results suggest the need for a holistic understanding of the essential structure of the lived experiences of homeless persons. Mental health professionals need to understand the homelessness experiences from the client view and to develop programs that can help homeless persons reintegrate into the community.

PURPOSE: The purpose of this study was to investigate factors affecting resilience in nursing students. METHODS: A survey was conducted with 200 nursing students at a college and a university in P city and K city. Data were collected from March 1 to 20, 2017, and analyzed with SPSS PASW 22.0. RESULTS: In the hierarchical analysis, factors affecting resilience were emotional intelligence (β=.39, p<.001), psychological well-being (β=.31, p<.001), and self-esteem (β=.16, p=.010). The variable that had the highest impact was emotional intelligence and the explanation power of the regression model was 65%(F=34.40 p<.001). CONCLUSION: The findings of this study indicate that emotional intelligence, psychological well-being, and self-esteem are essential for resilience in nursing students. Thus, enhancing emotional intelligence and psychological well-being would be an effective strategy to improve resilience in nursing students.

It has been found that acetylcholine releases at least two different substances from the vascular endothelial cells, i.e., relaxing factor and hyperpolarizing factor. The present study was armed to investigate whether and to what extent these factors are involved in the relaxation of the corpus cavernosum. The corpus cavernosum was isolated from male New Zealand white rabbits and suspended longitudinally in an organ bath. The corporal strips were precontracted with phenylephrine, tetraethylammonium (TEA) or potassium chloride, and their responses to electrical field stimulation (EFS) or exogenously-administered acetylcholine were examined. EFS caused a frequency-dependent relaxation of the corpus cavernosum precontracted with phenylephrine, which was significantly inhibited or abolished in the presence of procaine (3.5 x 0.0001mol/L) or ouabain (0.0001mol/L). The corporal preparation precontracted with TEA also showed a frequency-dependent relaxation, however, the degree of which was lower than that precontracted with phenylephrine. EFS was without a significant effect on the corporal preparation precontracted with KCl (3 x 0.01mol/L). Acethylcholine elicted a concentration-dependent relaxation of the corpus cavernosum, the magnitude of which was significantly diminished in the presence of L-NAME (0.0001 mol/L). The relaxation response to EFS of the corporal preparation precontracted with phenylephrine was significantly attenuated in the presence of L-NAME (0.0001 mol/L), in which the residual relaxation was completely abolished by glibenclamide (0.00001mol/L). The relaxation of the corpus cavernosum in response to EFS was reversed into a contraction by methylene blue (0.0001mol/L) or TEA (0.01mol/L). These results suggest that endothelium-derived relaxing and hyperpolarizing factors released upon neural stimulation mediate the relaxation of the corpus cavernosum. It is also suggested that EDRF activates soluble guanylate cyclase and EDHF does ATP-sensitive potassium channels.

PURPOSE: The purpose of this study was to explore the coping process of chief Executive Nurses(CENs) Who Had Experienced Unexpected Dismissal.The research question was "would you tell me about your experience of sudden dismissal?" METHOD: The methodology of collecting and analyzing data used in this study followed the ground theory of Strauss and Corbin (1998). Data were collected through in-depth interviews with open-ended questions about the subjects' coping experiences, which were audio-taped and transcribed. The survey was conducted between April and May, 2007. The subjects of this study were 5 CENs. RESULT: The results of the study are as follows. Core category of This Study was "Battling unsupported against the overwhelming reality." The participants had to face the most unexpected reality of being laid off. Their emotional/psychological response were betrayal, powerlessness, lonesomeness, sorrow, and hopelessness. They felt like a general who is facing overwhelming enemy in a war. The coping process was found to have four stages: shocked stage, resisting stage, negotiating stage and reflecting and transcending stage. CONCLUSION: The result of this study suggested that ceaseless exertion and cooperation at organizational and individual levels are needed to establish stable status and power of nursing departments and CENs in hospitals.
