Purpose. This study pursued the way for the effective application of the differentiated charge (Nursing grading system) by the nursing manpower which is performed for the nursing service quality improvement to the in-patients in Korea and the minimum employment problem solution of nurses. Methods. For this matter, the status of the nursing grade for 1,452 hospitals (44 high class general hospitals, 259 general hospitals, 265 hospitals, 59 oriental medicine hospitals and 825 recuperation hospitals) was identified which were registered in the Health Insurance Review and Assessment Service in March 2011 status quo. Results. In the most nursing grade by the kind of medical institutions, 70.5% of the nurses were third-graded in upper general hospitals, 38.1% were sixth graded in general hospitals, 62.7% were seventh-graded in oriental medicine hospitals and 40.4% were first-graded in recuperation hospitals. In the nursing grade by the scale of hospitals (in terms of the number of beds), there was a significant difference in general hospitals, but there was no significant difference between oriental medicine hospitals and recuperation hospitals. In the nursing grade by the location of hospitals and the foundation type of hospitals, there was a significant difference between general hospitals and recuperation hospitals. Conclusion. For the effectiveness of applying differentiated nursing fees by the number of nurses, it seems necessary to consider adjusting the present differentiated inpatient-charge system for the better so that small and medium-sized hospitals may induce more nurses.

Thirty cases of Kikuchi's lymphadenitis, diagnosed by fine needle aspiration cytology, were reviewed to determine the main cytologic features helpful in reaching a diagnosis. The patients(mean age 26.6 years, male: female = 1:3.8) presented with lymphadenopathy (cervical 24, submandibular 3, and axillary 1) with or without fever and local tenderness. Excisional biopsy was done for confirmation in 5 cases and the remaining 25 cases showed the similar cytologic and clinical features. In the aspiration smears of all cases, there was a heterogenous celluar mixture including frequent extracellular karyorrhectic nuclear debris, phagocytic histiocytes, plasmacytoid monocytes, and a variable number of polymorphous lymphocytes such as immunoblasts, activated large lymphocytes, and small mature lymphocytes. The characteristic cytologic features of Kikuchi's lymphadenitis were the following: (1) frequent extracelluar karyorrhectic nuclear debris in the background : (2) phagocytic histiocytes with eccentrically placed crescentic nuclei and abundant pale cytoplasm containing phagocytized karyorrhectic debris : (3) plasmacytoid monocytes, which were medium-sized cells with eccentrically placed round nuclei and amphophilic cytoplasm : (4) no neutrophilic background.

Objective : Endovascular treatment of large, wide-necked intracranial aneurysms by coil embolization is often complicated by low rates of complete occlusion and high rates of recurrence. A flow diverter device has been shown to be safe and effective for the treatment of not only large and giant unruptured aneurysms, but small and medium aneurysms. However, in Korea, its use has only recently been approved for aneurysms <10 mm. This study aims to compare the safety and efficacy of flow diversion and coil embolization for the treatment of unruptured aneurysms ≥7 mm. Methods : The participants will include patients aged between 19 and 75 years to be treated for unruptured cerebral aneurysms ≥7 mm for the first time or for recurrent aneurysms after initial endovascular coil embolization. Participants assigned to a flow diversion cohort will be treated using any of the following devices : Pipeline Flex Embolization Device with Shield Technology (Medtronic, Minneapolis, MN, USA), Surpass Evolve (Stryker Neurovascular, Fremont, CA, USA), and FRED or FRED Jr. (MicroVention, Tustin, CA, USA). Participants assigned to a coil embolization cohort will undergo traditional endovascular coiling. The primary endpoint will be complete occlusion confirmed by cerebral angiography at 12 months after treatment. Secondary safety outcomes will evaluate periprocedural and post-procedural complications for up to 12 months. Results : The trial will begin enrollment in 2022, and clinical data will be available after enrollment and follow-up. Conclusion : This article describes the aim and design of a multi-center, randomized, open-label trial to compare the safety and efficacy of flow diversion versus traditional endovascular treatment for unruptured cerebral aneurysms ≥7 mm.

This study attempts to analyze the factors affecting the intention of transferring to another hospitals among radiology technologists. 344 cases were reviewed in 5 university hospitals and 1 general hospital. Self-administered questionaire were given to study the socioeconomic characteristics, working conditions, job satisfaction level, and the reasons for transfer among the technologists. The major findings were as follows : 1. Job position and hospital characteristics had a statistically significant relationship with the intention of transferring to another hospital. 2. Those who were not satisfied with their salaries and promotional opportunity showed a higher tendency towards to transfer. 3. Those who were less satisfied with the opportunity for developing the personal ability and had the negative attitude on their job showed a higher tendency to transfer. 4. Those who did not sustain good relationship with their superiors and co-workers scored high on the tendency to transfer. 5. In the result of mutiple regression, recognition of radiation hazard, job satisfaction, satisfaction with salary levels, job attitude were significantly related to transfer. The above indicate that besides economic incentives, job satisfaction and organizational culture to promote their ability and form a good relationship with organization members were very important to decrease the intention of transfer. Since these results represent only 6 hospitals from a limited area, more hospitals nationwide, especially small and medium-sized institutions where there is a high turnover rate of employment, need to be examined in order to investigate the various factors that affect the intention of transferring.

Adenomyoepithelioma is an uncommon benign tumor of the breast. We present the fine needle aspiration cytologic features of adenomyoepithelioma in a 23 year-old Korean women, initially diagnosed as fibroadenoma. Aspiration cytologic findings of the left breast mass revealed high cellularity, small to medium sized, less cohesive epithelial clusters, rich naked cells and amorphous materials on background. The epithelial cells were round and uniform with no cytologic atypia or mitosis. Myoeplthelial cells were conspicuous with peripheral rimming along the epithelial clusters. Small amount of fibrotic stromal tissues were observed. Distinguishing features from typical fibroadenoma are less tight epithelial clusters, dyscohesive epithelial cell aggregates, more abundant naked cells and scant stromal tissue fragments.

The purposes of this study were to a) measure the service quality attributes of foodservice type such as school foodservice, hospital foodservice and business & industry(B&I) foodservice, managed by contract management company(CMC), b) compare with service quality attributes by CMC scale, c) analyze overall customer satisfaction(CS) by the foodservice type and the CMC scale, and d) identify the effect of service quality attributes on an overall CS by the foodservice type and the CMC scale. The questionnaires were handed out to 6,620 customers of 207 school, 38 hospital, and 86 B&I foodservices in 108 CMCs. The statistical data analysis was completed using SPSS Win(ver 12.0) for descriptive analysis, t-test, reliability analysis, and multiple linear regression analysis. From an analysis on service quality attributes, 'proper arrangement of table and chair at hall distribution(3.53)', 'operation of nutrition education(3.50)' were highly perceived to student, 'correctable serving(4.08)', 'serve at fixed distribution time(4.08)', 'kindness of serving employee(4.04)' were highly perceived to patient, 'employee's kindness(3.84)' were highly perceived to customer of B&I. In comparison of service quality attributes by CMC scale, most scores of large enterprise(LE) were significantly higher than small and medium sized enterprise(SME) in school foodservice, hospital foodservice and B&I foodservice. Overall CS levels were 3.53 out of a maximum 5 on B&I, 3.46 on school, and 3.44 on hospital and were evaluated differently CS score by CMC scale. Finally, regression results for the effects of service quality attributes on overall CS by each of foodservice type were identified significantly different service quality attributes by foodservice type such as school, hospital, B&I(p<.001) and by CMC scale. For considering the goal of enterprise on profit-making through CS and the needs of customer on CS at moment of truth(MOT), the findings should be applied to the CMC and the foodservice industry.

Background The radial forearm free flap (RFFF) has remained a leading choice of many plastic surgeons as a fasciocutaneous flap due to its versatility, pedicle length, and simple elevation technique. However, donor site morbidity has led many reconstructive surgeons to limit their use of the RFFF and to use other flaps instead. We propose that using a narrow RFFF (nRFFF) decreases the aesthetic and functional morbidity of the donor site. Methods We report our experiences with the nRFFF from April 2012 through May 2015 at the Department of Plastic, Reconstructive, and Hand Surgery at Liaquat National Hospital, Karachi. The donor defects were closed primarily. The Stony Brook Scar Evaluation Scale and comparison with the contralateral hand were used to assess aesthetic and functional outcomes, respectively. Results A total of 24 patients underwent nRFFF procedures during the study period. The donor arm showed excellent motor function in 22 cases (91.7%), and very good function in the remaining two cases (8.3%). The aesthetic outcomes were excellent in four patients (16.6%), very good in eight patients (33.3%), good in 10 patients (41.6%), and fair in two patients (8.3%) who developed a hypertrophic scar. All flaps were successful and there were no cases of partial or complete loss. Conclusions For small to medium-sized soft tissue defects, the nRFFF had acceptable outcomes due to its thinness, pliability, and major reduction in donor site aesthetic and functional morbidity.

In spite of the developing endovascular era, large (15-25 mm) and giant (>25 mm) wide-neck cerebral aneurysms remained technically challenging. Intracranial flow-diverting stents (FDS) were developed to address these challenges by targeting aneurysm hemodynamics to promote aneurysm occlusion. In 2011, the first FDS approved for use in the United States market. Shortly thereafter, the Pipeline of Uncoilable or Failed Aneurysms (PUFS) study was published demonstrating high efficacy and a similar complication profile to other intracranial stents. The initial FDA instructions for use (IFU) limited its use to patients 22 years old or older with wide-necked large or giant aneurysms of the internal carotid artery (ICA) from the petrous segment to superior hypophyseal artery/ophthalmic segment. Expanded IFU was tested in the Prospective Study on Embolization of Intracranial Aneurysms with PipelineTM Embolization Device (PREMIER) trial. With further post-approval clinical data, the United States FDA expanded the IFU to include patients with small or medium, wide-necked saccular or fusiform aneurysms from the petrous ICA to the ICA terminus. However, IFU is more restrictive in South Korea than in United States. Several systematic reviews and meta-analyses have sought to evaluate the overall efficacy of FDS for the treatment of cerebral aneurysms and consistently identify FDS as an effective technique for the treatment of aneurysms broadly with complication rates similar to other traditional techniques. A growing body of literature has demonstrated high efficacy of FDS for small aneurysms; distal artery aneurysms; non-saccular aneurysms posterior circulation aneurysms and complication rates similar to traditional techniques. In the short interval since the Pipeline Embolization Device was first introduced, FDS has been firmly entrenched as a powerful tool in the endovascular armamentarium. As new FDS are developed, established FDS are refined, and delivery systems are improved the uses for FDS will only expand further. Researchers continue to work to optimize the mechanical characteristics of the FDS themselves, aiming to optimize deploy ability and efficacy. With expanded use for small to medium aneurysms and posterior circulation aneurysms, FDS technology is firmly entrenched as a powerful tool to treat challenging aneurysms, both primarily and as an adjunct to coil embolization. With the aforementioned advances, the ease of FDS deployment will improve and complication rates will be further minimized. This will only further establish FDS deployment as a key strategy in the treatment of cerebral aneurysms.

This study examined the relationship between the number of medical technologists and the medical test count. Data was obtained from 441 medical technologists in a hospital through a self-reported questionnaire. The Pearson correlation test, student's t-test, ANOVA or descriptive statistics were performed for data analysis. The distribution of medical technologist according to the size of hospitals was small 5.8, medium 14.9, large 25.8, and super 45.4. The analysis demonstrated a relationship between the number of medical technologists and the number of medical tests in the field, number of clinical tests per MT, and number of optimal medical test per MT according to the hospital size (P<0.001). The average time for quality control by the department at a higher hospital was less than two hours. In terms of the satisfaction of salary, work environment, test accomplishment, and welfare service, the dissatisfaction of medical technologists in small and medium hospitals was higher than those in large and super hospitals. Overall, a focus on intensifying systemic supplementation and improving the condition of medical technologists is needed to provide reliable data for medical examinations in medical areas.

Purpose: This study was conducted to develop and test the effects of a program for practice application of intravenous infusion evidence based nursing practice (EBP) guidelines in small and medium-sized hospitals. Methods: A mixed method research design was used, combining non-equivalent control group pre-post test design with qualitative study analysis. The subjects consisted of 55 nurses. The practice application program was developed based on the Advancing Research and Clinical practice through close Collaboration (ARCC) model. Data were collected for analysis in the following areas: nurses' EBP organizational culture and readiness, EBP beliefs, EBP implementation, importance about intravenous infusion, and performance about intravenous infusion, with data assessed using valid and reliable instruments. Patient outcomes were collected from the hospital's medical records. Data were analyzed using t-test, χ2-test, and Shapiro-Wilk test, with qualitative content analysis used for interview data. Results: Following the intervention, nurses' EBP organizational culture and readiness, EBP beliefs, EBP implementation, and performance of intravenous infusion and perceptions of its importance showed significant improvement in the experimental group. Phlebitis rates decreased in the experimental group compared to the control group. Conclusion: This program is effective to improve nurse's perception and practice of evidence based nursing. Therefore we recommend to use this program at same levels of hospitals.
