Purpose: This study examines and compares the differences between self-esteem and health promotion behavior of health department and non-health department college students. Method: The research instruments were as follows : The first one is RSES developed by Rosenberg and translated into Korean by Jeon. The second one is HPLP developed by Walker et al, and including six subareas by Lee and modified to be suitable to Korean culture by Suh. Data were statistically analyzed with SPSS PC/12.0. Results : 1. Comparison of self-esteem had no significant difference(p=.190) and health promotion behaviors had significant differences(p=.000) between the two groups. 2. According to general characteristics and health-related characteristics, the differences of self-esteem in health department showed significant differences in grade(p=.020), sex(p=.000), age(p=.000), parents' economic conditions(p=.048), and smoking(p=.030) while non-health departments revealed significant differences in grade(p=.003), sex(p=.000), age(p=.000) and smoking(p=.001). 3. According to general characteristics and health-related characteristics, the differences of health promotion behaviors in health department showed significant differences in grade(p=.008), sex(p=.021), age(p=.000) and parents' economic conditions(p=.017) while non-health department revealed significant differences in sex(p=.000) and age(p=.000). 4. There were positive correlations between self-esteem, health promotion behaviors and subareas in health department (r=.422) and non-health department (r=.383). Conclusion: There were significant positive correlations between self-esteem and health promotion behaviors in health and non-health department college students. Therefore, health related programs should be developed to enhance self-esteem and health management by college students can influence themselves on self-esteem and health promotion behaviors.

Background: The purpose of this study is to identify factors that affect work dissatisfaction and turnover intention for dedicated nurses working in emergency departments of vulnerable areas of health care. The purpose of this study is to identify risk factors related to the working environment that influence job dissatisfaction and intention to turnover among dedicated nurses working in emergency rooms in areas of medical vulnerability. Methods: We conducted a survey of nurses working in emergency rooms in vulnerable areas of medical care, and the survey was conducted for two consecutive years. A logistic regression analysis was performed with the working environment variable as the independent variable and the work environment dissatisfaction and turnover intention as dependent variables, respectively. Results: The variables that significantly affected both dissatisfactions with the working environment and turnover intention at the current institution were age, overlapping work in other departments, and the total work experience of nurses. Annual salary, the average number of double-duty (continuous work) per month, type of work, and work experience of nurses at the current institution had a significant effect only on dissatisfaction with the working environment. Conclusion: The results of this study are thought to be of great help if the government takes reference when establishing medical policies in vulnerable areas in the future.

Background/Objectives: Shoulder function is an important aspect of health related quality of life (QOL). Neck dissection impairment index (NDII) is a simple shoulder-specific questionnaire. This study aimed to evaluate the association between QOL and NDII in patients who underwent neck dissection to validate the Korean version of NDII. Materials & Methods: This study enrolled 74 patients with head and neck cancer who underwent neck dissection from December 2013 to April 2014. Patients completed questionnaires on QOL including the European Organization of Research and Treatment of Cancer 30-item Core QOL questionnaire (EORTC QLQ-C30) and NDII which was translated into Korean. Validity was evaluated by calculating the Pearson correlation coefficient between NDII and EORTC QLQ-C30. Results: We compared preoperative, postoperative within a week, 1st and 3rd months NDII scores. The total NDII scores were 14.7, 47.4, 33.7 and 34.3 each. Clinical variables including gender, site of primary tumor, performing revision neck dissection, radiotherapy and flap reconstruction were not significantly associated with NDII. However NDII mean score of patients who underwent unilateral neck dissection over 3 levels is most increased after operation. During all periods NDII scores were significantly associated with functioning score. Although other scores are lower correlation than function scores, global health status scores and symptom scores are also correlation with NDII. Conclusion: NDII was valid instrument and can be used not only in the clinical practice to assess shoulder dysfunction but also in the simple instrument to evaluate global QOL in Korea patients with having neck dissection.

In the present study, the protective effects of Hizikia fusiforme and Chlorella sp. extracts on lead acetate-induced hepatotoxicity were investigated. Hepatic damage was induced in rats by intraperitoneal (i.p.) injection of lead acetate and the protective effects of H. fusiforme (HZK) and Chlorella sp. (CHL) extracts on lead acetate-induced hepatic damage in rat liver were examined. The results revealed significantly increased glutamic oxaloacetate and glutamic pyruvic transaminase levels in the group treated with lead acetate only (Pb group); oral administration of HZK and CHL extracts tended to decrease the enzyme levels similar to those observed in the control group. Regarding antioxidant enzymes, superoxide dismutase activity was increased in the Pb group and decreased in a concentration-dependent manner in the HZK- and CHL-treated groups. Glutathione levels were increased in a concentration-dependent manner in the HZK- and CHL-treated groups. There was no significant difference in catalase activity. Western blot analysis showed inflammation-related protein expression in mitogen-activated protein kinase and Nrf2 pathways was affected in the HZK- and CHL-treated groups. Therefore, HZK and CHL extracts exerted antioxidant and anti-inflammatory effects against lead acetate-induced hepatotoxicity. Development of functional health foods containing HZK and CHL extracts, which have hepatoprotective effects against inhaled lead acetate, should be considered.

Purpose: The aim of this study was to investigate the changes in perception of the New Diagnosis-Related Group (DRG)-based payment system, make overall evaluation after participation, and examine opinions on further policy improvement among employees of a public hospital participating in the pilot project in Korea. Methods: We investigated changes in perception of the New DRG-based payment system before and after participation in the pilot project using a qualitative research method. We conducted individual in-depth interviews with the management and healthcare professionals and Focus Group Interviews (FGIs) with the staff in the nursing and administrative departments. Results: Before implementing the pilot project of the New DRG-based payment system, the management was in favor of participating in the pilot project, whereas the healthcare professionals were strongly opposed to participation in the pilot project, and the staff in the nursing and administrative departments were slightly opposed to participation. After implementing the pilot project, there were remarkable changes in the perception of the New DRG-based payment system among healthcare professionals and the administrative staff. Healthcare professionals' perception was altered in a positive way, while the administrative staff's perception of the system became negative. Conclusion: There were no restrictions on clinical practice or deterioration of quality of care observed in association with the participation in the New DRG-based payment system. However, certain unintended consequences of the New DRG-based payment system may arise as well. Therefore, the government needs to examine the problems identified in this study to reflect on and improve the New DRG-based payment system for stable expansion.

The present study is designed to analyze reliability and validity of the instruments used to measure job stress of radiological technologists mainly by means of the questionnaires from 'Korean edition of NIOSH check list'. The subjects of this study are 890 radiological technologists active at 44 general hospitals in 16 provinces and cities across the country. The item-total reliability revealed that 10 factors in 6 are the major causes of stress in job life of radiological technologists. The measuring instrument proved to be valid with reliability coefficient of internal consistency by factors being more than 0.7. The factors found to be applicable herewith include limit and authority of job (0.73), cohesion within departments (0.86), resources control (0.81), mental requirements (0.85), job load (0.82), and job stability (0.72). When job autonomy item of causes are modified for proper use to radiological technologists, the measuring instruments are expected to show high reliability. It seems, however, necessary to develop a measuring instrument to analyze and use the validity of related measuring instruments since the reliability here was rated low, with statistical coefficients lower than 0.7 in such factors as job management (0.57), conflicts within departments (-1.13), sense of responsibility for patients (0.66) and usage of education (0.26). As this study was intended to examine reliability and validity of the concepts related to measurement of job stress on the part of radiological technologists, it nay not be proper to apply the results of this study to general use, but is advised to utilize them as basis for developing instruments to verify reliability and validity by comparing with and analyzing other measuring instruments.

Neuropathic pain is a complex state showing increased pain response with dysfunctional inhibitory neurotransmission. The TREK family, one of the two pore domain $K^+$ (K2P) channel subgroups were focused among various mechanisms of neuropathic pain. These channels influence neuronal excitability and are thought to be related in mechano/thermosensation. However, only a little is known about the expression and role of TREK-1 and TREK-2, in neuropathic pain. It is performed to know whether TREK-1 and/or 2 are positively related in dorsal root ganglion (DRG) of a mouse neuropathic pain model, the chronic constriction injury (CCI) model. Following this purpose, Reverse Transcription Polymerase Chain Reaction (RT-PCR) and western blot analyses were performed using mouse DRG of CCI model and compared to the sham surgery group. Immunofluorescence staining of isolectin-B4 (IB4) and TREK were performed. Electrophysiological recordings of single channel currents were analyzed to obtain the information about the channel. Interactions with known TREK activators were tested to confirm the expression. While both TREK-1 and TREK-2 mRNA were significantly overexpressed in DRG of CCI mice, only TREK-1 showed significant increase (~9 fold) in western blot analysis. The TREK-1-like channel recorded in DRG neurons of the CCI mouse showed similar current-voltage relationship and conductance to TREK-1. It was easily activated by low pH solution (pH 6.3), negative pressure, and riluzole. Immunofluorescence images showed the expression of TREK-1 was stronger compared to TREK-2 on IB4 positive neurons. These results suggest that modulation of the TREK-1 channel may have beneficial analgesic effects in neuropathic pain patients.
