OBJECTIVES: Cognitive psychological models propose that auditory hallucinations arise from a problem with monitoring one's auditory verbal imagery. Most auditory hallucinations are derogatory in content and accompany negative emotions. If auditory verbal imagery plays an critical role in the pathogenesis of auditory hallucination, it must be influenced by negative emotions. This study was aimed at understanding the influence of negative emotions on the development of hallucinations by investigating the way by which negative emotions have influence on cortical activity induced by auditory verbal imagery. METHODS: For both normal subjects and patients with schizophrenia, quantitative electroencephalography(Q-EEG) was applied during the auditory verbal imagery tasks using a two word list. The one word list accompanied negative emotion and the other accompanied neutral emotions. The difference of EEG activity between two tasks was compared by paired t-test. WE also compare the difference of the influence of negative emotions between normal subjects and patients with schizophrenia. RESULTS: In normal subjects, amplitude of beta wave was increased in temporal area such as TCP1, and, the amplitude of theta frequency wave was decreased in right hemisphere such as FP2, F4, C4, CP2, P4, But, in the schizophrenia group, there were no significant differences. CONCLUSION: These results may suggest that auditory verbal imagery with negative emotion requires more activation in left temporal area, but, appropriate activation may not achieved in schizophenia patients. So, the possibility that the resultant disturbance of verbal self monitoring may be related to auditory hallucination is suggested in this study.

Contact urticaria refers to a wheal-and-flare response occurring on the application of chemicals to intact skin. When contact urticaria is accompanied by systemic symptoms, it is known as the urticaria syndrome. Fourteen cases of cefotiam-induced contact urticaria have been reported in the foreign literature, but no such case, as far as we know, has been described in the Korean dermatology literature. We report a case of contact urticaria syndrome occurring in a 23-year-old nurse due to occupational contact exposure to cefotiam. She experienced generalized urticaria, itching of the skin, difficulty in breathing, and abdominal pain, when she was preparing an injection of cefotiam. An open patch test showed positive reactions to cefotiam, cefmetazole, and ceftriaxone. Since avoiding cefotiam, the symptoms disappeared and did not recurred.

PURPOSE: The purpose of this study was to investigate the moderating effects of social support between emotional labor and job satisfaction in clinical nurses. METHODS: Participants were 311 clinical nurses and data were collected from July 11th to 18th, 2014. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and hierarchical multiple regression with SPSS 21.0. RESULTS: The job satisfaction indicated a significant relationship to surface-acting (r=-.191, p=.001), deep-acting (r=.179, p=.002) and social support (r=.342, p<.001) respectively. Emotional labor significantly affected job satisfaction (F=11.592, p<.001), and explained 5.4% of the variance in job satisfaction. The social support acted as a moderator on the relationship between emotional labor and job satisfaction at significant level (F=11.416, p<.001). CONCLUSION: The results of this study suggest that it is important to develop social support promoting and stress relief program for clinical nurses to improve job satisfaction.

OBJECTIVE AND METHODS: To determine correlations among ambulatory renin activity, ambulatory blood pressure and microalbumin excretion rate, 66 Korean essential hypertensives were studied after 4 week wash-out period. The ambulatory blood pressure was monitored every 30 minutes and mean BP were calculated automatically. Urinary microalbumin excretion rate(UAER) and ambulatory plasma renin activity(aPRA) collected at mid-day were measured by radioimmunoassays. Subjectives were divided into 2 groups by aPRA value(2ng/ml/hr). RESULT: 14 cases were high renin group and 52 cases low renin group. The mean BP were 148.83/94.69mmHg in low renin group, and 146.57/98.07mmHg in high-renin group without difference. UAER were not different also between both groups. 23.07%(4/14) of non-dippers were included in high renin group and 25.58%(12/52) in low renin group without statistical difference. The aPRA was significantly related to UAER and systolic and diastolic mean blood pressure. Also UAER was related significantly to day mean blood pressures. CONCLUSION: Thus aPRA is thought to be a meaningful indicator to predict hypertensive renal target organ damage as well as blood pressure measured with 24-hr ABPM.

Neomycin is one of the aminoglycoside antibiotics and not uncommonly causes allergic contact dermatitis. Wool alcohol is one of the most widely used lanolin bases and rarely has been reported to cause allergic contact dermatitis. A 63-year-old male presented with a pruritic, erythematous swelling on the right periorbital area. He had a cataract operation on his right eye 10 days ago and has applied several eye drops and topical antibacterial agents. Patch test with Korean standard antigens and ophthalmic preparations revealed strong positive reactions to neomycin sulfate and the Maxitrol ointment composed of dexamethasone, neomycin sulfate and polymyxin B, and positive reaction to wool alcohol. Neomycin may be the major causative agent to produce allergic contact dermatitis, and wool alcohol also has some relation to it.

Purpose: To retrospectively compare the fixation methods for reattaching a trochanteric fragment in a pertrochanteric fracture treated with bipolar hemiarthroplasty. Materials and methods: Forty cases of an unstable femur pertrochanteric fracture were analyzed and followed up for average of 19(6~40) months. There were 18 cases fixed with tension band wiring (group 1), 7 cases treated using modified tension band wiring with K-wires (group 2) and 15 cases treated with the GTRD (Greater Trochanteric Reattachment Device) (group 3). Result: Group 1 was treated with simple a surgical procedure and the results were good. The second group had firm fixation postoperatively but required additional surgery in two cases to remove the K-wires because of wire migration after ambulation. Group 3 had relatively good results but required more dissection and a longer operating time. Conclusion: Tension band wiring or GTRD are good fixation methods for reattaching trochanteric fragments in pertrochanteric fractures. Moreover, tension band wiring is recommended for old osteoporotic patients due to a simple procedure and firm fixation. The use of modified tension band wiring using K-wire or a Steinmann-pin should not be used due to the possibility of distant migration.

OBJECTIVE: The purpose of this study was to evaluate how the friction that occurs during the sliding movement of the archwire through esthetic brackets is differently affected by bracket materials, slot designs, and tip angulations of the archwire. METHODS: Eight types of brackets with 0.018 inch slots (composite: Brillant (BR); composite with metal slot: Spirit MB (SP); ceramic: Inspire (IN), Signature (SI), Cristaline V (CR); ceramic with metal slot: Clarity (CL), Luxi II (LU); and metal bracket: Integra (IT)), and placed into groups of 20 brackets in each group, were tested in artificial saliva with 0.018 inch stainless steel wire. The wire tip angulations were given as 0, 4 and 8 degrees. RESULTS: CR group significantly showed the lowest frictional force with all wire tip angulations of 0, 4, and 8 degrees. IN significantly showed the highest frictional force (p < 0.001). BR (polyoxymethylene) had significantly less frictional force than SP (polycarbonate) (p < 0.001) and showed no significant difference between metal brackets. Friction was increased as the wire tip angulations were increased, but no notches were observed on any parts of the archwire. CONCLUSIONS: According to the results of this study, esthetic brackets are superior or similar to SS brackets from a frictional point of view.

This study was performed to examine the health risks according to the obesity types based upon body mass index (BMI) and waist circumference (WC) cutoffs. The subjects were 8,966 adults aged 40-79 years from the 1998, 2001 and 2005 Korean National Health and Nutrition Examination Surveys. The subjects were classified into 4 types of obesity groups based on BMI and WC: BMIWC (BMI > or = 25 kg/m2 and WC >or = 90 cm for males and > or = 85 cm for females), WC (BMI < 25 kg/m2 and > or = 90 cm for males and > or = 85 cm for females), BMI (BMI >or = 25 kg/m2 and < 90 cm for males and < 85 cm for females), normal (BMI < 25 kg/m2 and < 90 cm for males and < 85 cm for females) groups. More than half (n = 5,103) of the subjects fell into the normal group and BMIWC group accounts for 58%, followed by BMI group of 27% and WC group of 16%. Mean ages of subjects were highest in WC group and lowest in BMI group. Blood levels of total cholesterol, triglyceride, LDL-cholesterol and glucose, and blood pressures were higher and HDL-cholesterol was lower in 3 types of obesity groups (BMIWC, WC, BMI) than in the normal group. Among the 3 obesity groups, energy and fat intake was significantly higher in BMIWC than in normal group in males, however, no differences were found among the 4 groups in females. The three obesity groups had greater odds ratios for hypertension, diabetes mellitus, hypercholesterolemia, hyper-LDL-cholesterolemia, hypo-HDL-cholesterolemia, hypertriglyceridemia, and metabolic syndrome compared to the normal group. Among 3 obesity groups, BMIWC group had the highest odds ratios for hypertension, diabetes mellitus, and metabolic syndrome. Especially BMIWC and WC groups showed the highest odds ratios for diabetes mellitus and metabolic syndrome, suggesting the potential role of abdominal obesity in diabetes mellitus and metabolic syndrome. Our data indicate that different types of obesity may show different degrees of health risks. The appropriate selection and use of obesity indexes may be effective for management of obesity as well as obesityrelated diseases.
