The purpose of this study was to evaluate the efficacy of brachytherapy of breast cancer by dose assessment which a steady increased in Korea women. The dose assessment was performed using the MCNPX program, a MonteCarlo simulation technique. The sources used for brachytherapy was 192Ir. And nanoparticle which used for dose enhancement was gold. The density of nanoparticle was 7, 18 and 30 mg. Evaluation of absorbed dose according to distance is measured at a distance of 30, 50, 100 and 200 cm from the patient. As a result, The breast absorbed dose results increased in proportion to the density of nanoparticle. And the surrounding organs were not significantly different according to the density. But, in some organs, the absorbed dose decreased as the density of nanoparticles increased. Absorbed dose according to the distance was in inverse proportion to distance.

Purpose: This study aimed to identify the influence of nurses' resilience and anger expression styles on their nursing work performance in emergency departments. Methods: The study included 107 nurses from 5 hospitals in Seoul and Gyeonggi-do who consented to participate. Data ware collected from March to April 2016. Multiple regression analysis was used to identify factors influencing nurses' performance. Results: Nurses' performance was higher when resilience was high and anger expression was low. The result of the multiple regression indicated that present working years in the emergency room, work satisfaction, anger expression, anger control, and resilience predicted 39.4% (F=7.27, p<.001) of the nursing performance of hospital nurses in emergency departments. The most powerful predictor was resilience (${\beta}=.45$, p<.001), followed by anger-out (${\beta}=-.25$, p=.006). Conclusion: This study showed that the most influential variables of work performance in emergency nurses ware resilience and anger expression. To enhance the nursing performance of hospital nurses in emergency departments, it is necessary to develop and implement mentorship programs that enhance resilience and educational programs that help them manage their anger.

Purpose: The purpose of this study was to compare communication competence, nursing professionalism, work environment and job satisfaction between outpatient nurses and ward nurses, and to identify the correlation among variables. Methods: The participants were 90 outpatient nurses and 98 ward nurses at the two general hospitals. Data were collected using self-administered questionnaires. Data were analyzed using descriptive statistics, ${\chi}^2-test$, independent t-test and Pearson's correlation coefficient. Results: There were statistically significant differences between two groups in nursing professionalism, possibilities for development, commitment to the workplace, social support from colleagues, social community at work and job satisfaction, outpatient nurses showed higher level than ward nurses except commitment to the workplace. The work environment variables and nurses' job satisfaction were mostly correlated. Job satisfaction showed significant negatively correlated with quantitative demands, emotional demands and role conflicts in both groups nurses. Conclusion: These findings showed that nursing work environments were the most important factor for job satisfaction of both group nurses. Therefore, it is necessary to put efforts in improving nursing work environment and to develop diverse strategies for human resource management.

The nurses manually carry out the intravenous therapy for the patients. Using an Arduino, the fine flow controlling device was invented to provide an ongoing patient care. The medication is injected through a peristaltic pump, and the amount of the solution is controlled with a RGB color sensor. The power of the device is supplied through the batteries. An amount of the injection is measured with LIG strain sensor fabricated by 355nm UV pulsed laser. This system will provide a better medical service.

Malignant melanomas, which are rarely found in the Asian population, are malignant tumors or melanocytes that manifest in the skin mucosa. Malignant melanomas of the anorectum are very rare and account for approximately 1% of all malignant melanomas in the Asian population. Here, we present a rare case presenting a malignant melanoma of the anorectum. An 85-year-old woman visited the hospital with bloody stools and an anal mass. Sigmoidoscopy revealed a black mass protruding from the anus, and the scope was able to penetrate the anorectal mass. Close-up endoscopy revealed black moles of different sizes scattered across the rectal mucosa. PET-CT indicated multiple FDG uptakes in the liver, indicating multiple metastases. Pathologic examination led to the detection of malignant melanocytes with dark brown deposits. The patient's immunohistochemical markers were positive for melanin-A antibodies and HMB-45, indicating a malignant melanoma. As there was no evidence of malignant melanomas on the skin, the patient was diagnosed with primary malignant anorectal melanoma with liver metastases.

Sclerotic fibroma or storiform collagenoma is a rare benign neoplasm that predominantly affects the skin layer of the head, neck, or limbs. Less frequently, it occurs in non-dermal spaces such as the subcutaneous layer. No cases have been reported in the axilla, and imaging findings of this rare entity have not been described in the literature so far. We present a case of sclerotic fibroma in the deep subcutaneous fat layer of the axilla and describe its ultrasound and computed tomography imaging features.

Renal epithelioid angiomyolipoma (EAML) is a rare variant of angiomyolipoma (AML), with a prominent epithelioid component. EAML usually presents as a large heterogeneous soft tissue lesion with intratumoral hemorrhage and variable necrosis or cystic changes. We present a case of multiloculated cystic renal EAML mimicking renal cell carcinoma in a 64-year-old female. Intracystic massive hemorrhage, hyperattenuating wall and septa on an unenhanced study, and enlarged intratumoral vessels can be helpful imaging features for distinguishing renal EAML from renal cell carcinoma.

Clear cell sarcoma-like tumor of the gastrointestinal tract (CCSLTGT) is a rare malignant mesenchymal tumor of the gastrointestinal (GI) tract with a high probability of local recurrence and distant metastasis in young adults. To the best of our knowledge, only seven case reports have described the imaging findings of a CCSLTGT originating from in the small intestine in English literatures so far. Therefore, we report the imaging findings of a CCSLTGT that occurred in the small intestine of a 22-year-old female and summarize the imaging findings of the previous reports.
