PURPOSE: The purpose of this study was to investigate the relationship among family functioning, empathy and aggression by high school students. METHODS: This was a descriptive study. The survey participants were 467 high school students from M city. Data were collected from November 29 to December 7, 2012 and self-report questionnaires including a Family Adaptability Cohesion Evaluation Scale, Interpersonal Reactivity Indexes, and an Aggression Questionnaire. The collected data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, stepwise multiple regression. RESULTS: The majority of the subjects were 2nd graders (42.0%) and female (57.2%). 59.7% of the subjects had religion, 84.8% were living together with parents. The mean ages of their fathers and mothers were 49.90+/-0.20 and 46.85+/-0.19 respectively. Aggression was found to have a statistically negative correlation with family functioning and empathy. Stepwise multiple regression analysis revealed that the most powerful predictor of aggression was empathic concern. Empathic concern, family cohesiveness, perspective taking, personal distress and gender accounted for 16.7% of the variances. CONCLUSION: It is necessary to provide aggressiveness reduction programs for high school students that consider their family functioning and empathy.

The advent of computerized cranial tomography made a greater advance in the diagnosis of very wide variety of intracranial lesions. Authors analyzed 58 pathologically proven sellar and parasellar tumors examined at Kyung Hee Un-iversity Hospital from Oct. 1977 to Jun. 1981 and the results were as follows; 1. The distribution of the tumors is 28 pituitary adenomas, 18 craniopharyngiomas, 5 meningiomas, 4 germinomas, 2 astrocytomas, and 1 sphenoid mucocele. 2. In pituitary adenoma, the precontrast CT scan of tumors appeared as isodensity in 11 cases, mixed density in 8 cases, high density in 6 cases, and low density in 3 cases, and associated with destruction of sellar turcica in 15 cases, calcification in 3 cases, and hydrocephalus in 2 cases. The postcontrast CT scan study revealed 24 cases of contrast enhancement, including 17 cases of homogenous and 7 cases of ring or rim enhancement. 3. In craniopharyngioma, the precontrast CT scan of tumors appeared as low density in 12 cases, isodensity in 4 cases and high density in 2 cases and associated with calcification in 16 cases, hydrocephalus in 15 cases and destruction of sellar turcica in 2 cases. The postcontrast CT scan study revealed no enhancement in 10 cases and contrast enhancement in 8 cases including 6 of ring enhancement and 2 heterogenous enhancement.

BACKGROUND AND PURPOSE: The purpose of this study is to compare two clinical predictive rules, the pre-arrestmorbidity(PAM) index and the prognosis-after-resuscitation(PAR) score, which predict failure to survive following in-hospital cardiopulmonary resuscitation(CPR). METHOD: The study population consisted of 162 consecutive adult patients who underwent CPR at Wonju Christian Hospital over a year period. The PAM index and PAR score were calculated from the most recent data available for each variable prior to cardiac arrest. Each predictive tool was compared between the group of discharge alive and the group of in-hospital mortality. Performance of the predictive scores was also compared by receiver-operating characteristic(ROC) curves where appropriate. RESULTS: PAM index of study population was 4.39+/-2.69 and PAR score was 2.99+/-3.36. PAM index in the group of discharge alive was 1.87+/-2.79, and PAM index in the group of ih-hospital mortality was 4.51+/-2.62. PAR score in the group of discharge alive was 0.75+/-1.75, and PAR score in the group of in-hospital mortality was 3.1+/-3.4. The PAM index identified 15 patients with a score>8, while the PAR score identified 39 patients with a score>4, none of whom survived. The sensitivity of the PAR score for the prediction of failure to survive was 25%, while that of the PAM index was 10%; neither index incorrectly identified a patient as a non-survivor who eventually survived. Both of predictive methods were not significantly different in the ROC curve. CONCLUSION: Although further confirmation is necessary, PAM index and PAR score may provide useful prognostic information to physicians and patients involved with decisions about do-no- resuscitate orders.

A 25-year-old male patient was received emergency operation, open reduction and tenorrhaphy owing to degloving injury on the dorsum of his left hand, under axillary brachial plexus block using a transarterial approach. Following operation, he revealed the signs and symptoms of brachial plexus injury such as weakness, sensory deficit and tingling sensation on his left forearm and hand. The finding on electromyography (EMG), performed on the 16th postoperative day (POD), was indicative of left incomplete brachial plexus injury, mainly in medial cord and ulnar nerve, and partially median and radial nerve at/above the axillary level. The signs and symptoms were improved slightly on POD 8 and a lot on POD 23. The complete recovery of symptoms and regeneration of injured nerve on EMG were confirmed 3 months following operation. In this case, the causative factors of brachial plexus injury were suggested in stretching of the brachial plexus due to improper positioning of injured arm during or after operation, combined with or without injury due to nerve block or tourniquet compression.

Environmental pressures from such sources an economic condition, the government and inter-institutional competition create managerial challenges. Economic pressures may be forcing dietetic dept, in hospital to utilize cost, benefit analysis to assist them in their problem solving. Cost, benefit analysis have been widely used in business, industry and many other fields with only limited application to foodservice. Due to the lack or this information the purposes of this study were to identify use of cost, benefit analysis in hospital foodservice system to evaluate the economic efficiency of alternatives, and to make recommendation for operation system change. Using the cost?benefit method, cash flows are separated into cost and benefits. For an alternative to be selected, indicators, such as NPV, benefit-cost ratio (B/C ratio) with 5% discount rate per annum. The sensitivity analysis was also conducted with difference rate 3%, 7% respectively and reduced employee payroll change. The result of this study can be summarized as follows : 1. The total cost of investment for operation system change was 390,570 thousand won and the total benefit through operation system change was 865,808 thousand won. 2. Net present value(NPV) for 5 years was 475,239 thousand won and benefit-cost ratio was 2.22. 3. In sensitivity analysis with different discount rate 3%, 7%, benefit-cost ratio was 2.25, 2.18 respectively, with total reduced employee payroll change, benefit-cost ratio was 2.86. In conclusion, total benefits were exceeded total costs. Therefore, the project of operation system change in hospital foodservice was found to be economically efficient.

The aim of this study was to investigate respondents' satisfaction with smart device-based testing (SBT), as well as its convenience and advantages, in order to improve its implementation. The survey was conducted among 108 junior medical students at Kyungpook National University School of Medicine, Korea, who took a practice licensing examination using SBT in September 2015. The survey contained 28 items scored using a 5-point Likert scale. The items were divided into the following three categories: satisfaction with SBT administration, convenience of SBT features, and advantages of SBT compared to paper-and-pencil testing or computer-based testing. The reliability of the survey was 0.95. Of the three categories, the convenience of the SBT features received the highest mean (M) score (M= 3.75, standard deviation [SD]= 0.69), while the category of satisfaction with SBT received the lowest (M= 3.13, SD= 1.07). No statistically significant differences across these categories with respect to sex, age, or experience were observed. These results indicate that SBT was practical and effective to take and to administer.

PURPOSE: To determine (1) the relationship between the cortical defects seen on 99 mTc-DMSA renal scans and age, and (2) the presence and degree of vesicoureteral reflux, and then to depict the risk factors for cortical defects in children with acute urinary tract infection (UTI). Furthermore, to assess the diagnostic value of VCUG in predicting a defect on 99 mTc-DMSA renal scans. MATERIALS AND METHODS: We studied 134 kidneys in 67 children aged 15 days-10 years (M:F=39:28) in whom symptomatic UTI was present. In all these children, both DMSA renal scans and voiding cystourethrography (VCUG) were performed. Scanning took place within 7 days of diagnosis and VCUG was performed after one month of diagnosis. Scintigraphic findings were graded according to the extent and number of cortical defects. We evaluated the relationships between the cortical defects seen on DMSA scans and age, and the grade of vesicoureteral reflux. The diagnostic value of VCUG in predicting cortical defects was analysed. Results: The prevalence of cortical defects was greater in patients older than two years (38/54, 70%) than in those aged less than two (38/80, 48%). The frequency of cortical defects was related to vesicoureteral reflux (p<0.05) and grade of reflux (p<0.05). As this latter increased, the extent of cortical defects also increased (p<0.05), and DMSA scans revealed the presence of these in 76 of the 134 kidneys (57%) with acute UTI. In 30 of these 76 (39.5%), VCUG demonstrated the presence of vesicoureteral reflex. On the other hand, vesi-coureteral reflex was found in 36 of the 134 kidneys (27%), and in 30 of these 36 (83%), cortical defects were noted. The sensitivity of VCUG in predicting cortical defect was 39.5%, while specificity was 89.7%. The positive predictive value for defects was 83.3%, and the negative predictive value was 53.1%. The relative risk of cortical defect in the presence of vesicoureteral reflux was 1.78. CONCLUSION: Renal cortical defects are significantly related to age and grade of vesicoureteral reflux. Risk factors for developing cortical defects were older age (> or =2yrs) at the time of acute UTI, and high grade of vesicoureteral reflux. The specificity of VCUG in predicting cortical defects is relatively high but the sensitivitiy is low, and a significant proportion of cortical defects therefore occurred in the absence of vesicoureteral reflux.

Sinonasal neuroendocrine carcinoma is a rare disease, and reports focusing on the MR imaging findings of sinonasal neuroendocrine carcinoma are extremely rare. Threrefore we intend to report 2 cases of histologically confirmed neuroendocrine carcinoma. A 62-year-old man and a 74-year-old man are both presented with nasal bleeding. Computed tomography(CT) images of the 2 patients showed large, ill-defined masses in sinonasal cavities with adjacent bony destructions. MR images showed masses with isosignal intensity on T1-weighted images and mixed iso- and high signal intensity on T2-weighted images. Postcontrast MR images showed heterogenous enhancement of masses with necrosis. Adjacent bony destructions were also noted on MR images. In both cases, peritumoral cystic lesions or mucoceles with high signal intensity on T1-weighted images were noted in sphenoid sinus. Both of the CT and MR imaging findings of the 2 patients were nonspecific which are usually seen in malignant tumor. But further study is needed for the significance of the peritumoral cystic areas adjacent the tumors.
