Intraperitoneal adminstration of radioisotopes is suggested to treat the metastatic ovarian cancer in the pertioneal cavity. Administering beta-emitting radioisotopes into the pertioneal cavity allows the maximum energy delivery to the cancerous cells of the pertioneal wall surface while sparing the normal cells located in deep site of the peritoneal wall. In this study, dose estimates of the peritoneal wall are provided to be used for prescribing the amount of 166Ho-chitosan complex administered. The 166Ho-chitosan complex diffused in the peritoneal fluid may attach to the peritoneal wall surface. The attachment fraction of 166Ho-chitosan complex to the peritoneal wall surface is obtained by simulating the ascites with Fischer rats. Both volume source in the peritoneal fluid and the surface source over the peritoneal wall surface are counted for the contribution to the peritoneal wall dose. The Monte Carlo code EGS4 is used to simulate the energy transfer of the beta particles emitted from 166Ho. A plane geometrical model of semi-infinite volume describes the peritoneal cavity and peritoneal wall. A semi-infinite plane of 10 micrometer in thickness at every 1 mm of depth in the peritoneal wall is taken as the target in dose estimation. Greater han 98 percents of attachment fraction has been observed from the experiments with Fischer rats. Given 1.3 microcurie/cm2 and 2.4 microcurie/ml of uniform activity density, absorbed dose is 123 Gy, 8.59 Gy, 3.00 Gy, 1.03 Gy, and 327 Gy at 0 mm, 1 mm, 2 mm, 3 mm, and 4 mm in depth to the peritoneal wall, respectively.

PURPOSE: This study aimed to develop a model for estimating the quality of life mediated by adaptation to changes experienced after stomach cancer diagnosis and surgery in patients with gastrectomy and to verify the model based on the Cancer Survivor Adaptation Model by Naus et al. (2009) and literature reviews. METHODS: Data was collected from 297 gastric cancer patients who underwent a gastrectomy at an outpatient clinic of two university hospitals in Daegu city from May to August, 2016. The exogenous variableswere perceived gastrointestinal symptoms, self-efficacy, anxiety, social support, and spiritual well-being. The endogenous variableswere adaptation and quality of life, and adaptationwas themediating variable. For data analysis, structural equation modeling was performed using IBM SPSS 21.0 and AMOS 18.0. RESULTS: The fitness parameters of the final model showed a reasonable fit to the data. Based on R², the exogenous variables explained 73.9% of the quality of life of stomach cancer patients who underwent surgery, through the mediation of adaptation; adaptation alone explained 73.5% of quality of life. Adaptation of stomach cancer patients with gastrectomy was a factor that strongly influenced their quality of life. CONCLUSION: It is important for gastric cancer patients with gastrectomy to adapt well to changes after surgery in order to improve the quality of life. Nursing interventions to aid successful adaptation would ultimately exert positive influences and improve the patients' quality of life.

PURPOSE: Computed tomographic(CT), ultrasonographic(US) findings of solid and papillary epithelial neoplasm of the pancreas were correlated with pathologic findings for the better understanding of this disease entity. METHODS AND MATERIALS: A retrospective review of CT and US of 14 cases of solid and papillary epithelial neoplasm of the pancreas was carried out in terms of the margin, internal architecture, caicification and septation, and this was correlated with gross pathologic findings. RESULTS: CT and US findings were well defined round masses consisting of both solid and cystic components. Five cases were cystic, four cases were solid and five cases were mixed. Cystic portion of the tumor represented variable degree of hemorrhagic necrosis. Six cases contained foci of calcification, which were linear, marginal and amorphous. Marginal calcification interfered US examination of the mass in three cases. Internal septurn was demonstrated in four cases on CT, one case on US and three cases on gross specimen. CONCLUSIONS: Our results indicate that calcification and internal septurn were considered as a part of radiologic findings in solid and papillary epithelial neoplasm of the pancreas.

Purpose: One of the many challenges health care leaders face is understanding what nurse turnover is and what can be done about it. This study was conducted to understand the effect of reality shock, nursing professionalism and social support of new graduate nurses on their intention of retention. Methods: This study used a cross-sectional descriptive survey design. Data were collected from 151 new graduate nurses working in general hospitals in South Korea. Data were analyzed using the IBM SPSS 25.0 program. Results: New graduate nurses’ intention of retention had relationship with Reality shock, nursing professionalism, social support, work experience, working in desired unit and monthly income. Factors associated with intention of retention were reality shock (β=-.26, p<.001), nursing professionalism (β =.25, p=.001), colleague’s support (β=.23, p<.001), work experience (β=-.21, p=.003) and monthly income (β=.16, p=.021). These factors explained 40.3% of the intention of retention. Conclusion In order to improve new graduate nurses’ intention of retention, it is necessary to improve nursing professionalism and colleague’s support while reducing reality shock. In addition, customized education considering the career of new graduate nurses will be necessary to improve their level of intention of retention.

PURPOSE: Injuries are the most important cause of morbidity and mortality in the childhood population worldwide. Thus, this study was down to investigate the type and the severity of injuries according to the age group in childhood. METHODS: A survey of injury information and a chart review were done on 378 children (257 boys, 121 girls) who visited the Emergency Departments of Asan Medical Center from March 1, 2009, to March 31, 2009. To determine differences in injury mechanism, accident place, injury site, New Injury Severity Score (NISS) and Pediatric Trauma Score (PTS), we divided the 378 patients into 4 group: under 1 year, 1 to 4 years, 5 to 9 years, and 10 to 15 years. RESULTS: The mean (+/-SD) age of the study group was 5.1 (+/-4.4) years. Two year olds formed the largest group of injured children, with 77 cases (20.4% of the total). The most common cause of injury in childhood was being hit by an object (26.2%). Falls were frequent in the under-1-year group (22.2%) and slip downs (30.1%) were more frequent in 1-to-4-year group. More than half (53.4%) of the injuries occurred in the home, and the most common places of home-related injuries were the living room (41.1%) and the bedroom (31.2%). The mean (+/-SD) NISS was 1.5 (+/-1.8), and traffic accidents had the highest NISS (2.8+/-5.1). Injuries occurred most frequently during the evening. The peak period was 4:00 PM to 8:00 PM (33.7%). CONCLUSION: Patterns of childhood injury by age group were considerably different, and less severe and nonhospitalized injuries were common. Thus, need to improve surveillance of a variety of injuries, promote intersectional collaboration, build institutional capacities and mobilize community support and policy as an investment in prevention.
