OBJECTIVES: We investigated the effects of changes in obesity and life style factors, such as cigarette smoking, alcohol drinking, and exercise, on the changes in blood pressure and serum cholesterol among Korean men. METHODS: This study included 7,205 healthy male employees in the steel manufacturing industry. Each subject underwent health examination in 1994 and was re-examined in 1997. The study subjects were classified into four categories, according to changes in body mass index (BMI) (loss; stable; mild gain; severe gain), cigarette smoking (quitter; non-smoker; smoker continued; smoker started), alcohol drinking (quitter; non-drinker; drinker continued; drinker started) and exercise (more exercise; continuous regular exercise; continuous irregular or no exercise; less exercise), respectively. We evaluated the relationship between the categories of change in those independent variables and the changes in blood pressure and serum cholesterol, adjusted for BMI in 1994 and age by analysis of variance. RESULTS: The change in systolic blood pressure was positively associated with the changes in BMI (p<0.001) and drinking (p=0.001), but negatively with smoking (p=0.004), compared to the first category of each independent variables. The systolic blood pressure was significantly less increased in the continuous smoking group than quitter or non-smoker. The changes in diastolic blood pressure and serum cholesterol appeared to have statistically significant linear relationships only with the change in BMI. The change in exercise showed a marginal significance with diastolic blood pressure (p=0.088). CONCLUSIONS: These prospective data emphasize the importance of obesity as a determinant of the changes in blood pressure and serum cholesterol. In addition, the changes in smoking and drinking habits can affect systolic blood pressure.

The nucleotide sequences of the internal transcribed spacer (ITS) regions of the ribosomal DNA including the 5.8S ribosomal RNA gene (rDNA) have been determined for 11 species in order to analyze their intrageneric relationships. The total length of these sequences ranged from 530 nucleotides for Trichoderma reesei KCTC 1286 to 553 nucleotide for Trichoderma koningii IAM 12534. Generally speaking, the length of ITS1 region was about 30 nucleotides longer than that of the ITS2 region. Also, the sequences of 5.8S rDNA were more conserved in length and variation than those of ITS regions. Although the variable ITS sequences were often ambiguously aligned, the conserved sites were also found. Thus, a neighbor-joining tree was constructed using the full sequence data of the ITS regions and the 5.8S rDNA. The Trichoderma genus used to be grouped on the basis of the morphological features and especially the shape of phialides needs to be reexamined. The phylogenetic tree displayed the presence of monophylogeny in the species of Trichoderma. Therefore, it was difficult to distinguish the intrageneric relationships in the Trichoderma genus.

PURPOSE: The purpose of this study was to explore the levels of disaster preparedness competency in public health workers and identify influential factors on disaster preparedness competency. METHODS: The data was collected through self-report questionnaires from a convenience sample of 281 public health workers in 2014 in Korea. The data was analyzed using descriptive statistics, t-test, ANOVA, and multiple regression. RESULTS: The mean disaster preparedness competency score was 2.77 and the mean disaster educational needs score was 4.01. Disaster preparedness competency had a statistically significant difference by gender, position, experience of disaster education in workplace, and experience of BLS education. As a result of the multiple regression analysis, disaster preparedness competency accounted for 11.6% of the variance by gender, experience of disaster education in workplace, and experience of BLS education. CONCLUSION: The results of this study reveal that gender, strengthening education of disasters in the workplace, and education of BLS should be taken into consideration and integrated when developing an effective educational program in order to enhance disaster preparedness competency in public health workers.

PURPOSE: To determine the usefulness of MR urography technique for the evaluation of urinary systems in patients with obstructed urinary tract and normal volunteers with non-obstructed urinary tract after intravenous normal saline and diuretic injection. MATERIALS AND METHODS: Three normal volunteers and 12 patients with urinary tract obstruction [ureteral calculi(n=8), extraurinary mass(n=1), ureteral tumor invasion(n=3)] underwent MR urography using a 1.0T scanner and a 2D non-breath-hold heavily T2-weighted fast spin-echo sequence. These acquisition were postprocessed with a maximum intensity projection (MIP) algorithm. Two acquisitions were performed, the first prior to saline solution infusion following standard MR urography procedures, and the second, within 2-3 minutes of the infusion of 250 ml saline solution followed by 20 mg of Lasix administered intravenously. For this latter, drug-induced MR urography procedures were followed. RESULTS: In healthy volunteers (n=3) and those experiencing partial obstruction (n=4) by a urinary stone, drug-induced MR urography provided better images of the urinary tract than did standard MR urography. In those in whom a urinary stone or tumor had caused complete obstruction (n=8), standard MR urography provided good images, as did drug-induced MR urography. CONCLUSION: In patients with a partially or non-obstructed urinary tract, drug-induced MR urography provided better anatomic and functional details of the kidney and urinary tract than did standard MR urography. In those experiencing complete obstruction of the urinary tract, however, standard or drug-induced MR urography permitted very adequate evaluation of the tract, and drug-induced MR urography was unnecessary.

PURPOSE: To evaluate effect of postoperative radiotherapy on survival and local control for patients with non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Ninety two NSCLC patients with N1or N2 involvement who were treated with postoperative radiotherapy following surgery with curative intent from May 1987 to October 1999 were retrospectively analyzed. Age of the patients was ranged from 32 to 78 years. According to TNM Stage, 35 patients had Stage II and 57 had Stage III disease. There were 49 patients with N1 involvement and 43 patients with N2 involvement. Fifty six patients were noted to have T1~2 tumors and 36 patients to have T3~4 tumors. Delivered total dose was ranged from 40 to 60 Gy. Majority of patients received 50 Gy or 50.4 Gy. Follow-up period was ranged from 9 month to 7 years with median follow-up of 26 months. RESULTS: Overall survival rates at 3 and 5 years for entire group of patients were 46% and 38%, respectively. Corresponding disease free survival rates were 44% and 36%. There was significant difference in survival between patients with Stage II and Stage III disease (50% vs 28% at 5-year). Five year survival rates for N1 and N2 patients were 52% and 20%, respectively (p<0.05). These were 40% and 34% for patients with T1~2 tumors and T3~4 tumors. There were documented local relapses in 13% of the patients. For patients with N1 and N2 Stage, local relapse rates were 8% and 18%, respectively. CONCLUSION: Our study confirms that postoperative radiotherapy for patients with non-small cell lung cancer improves local control. However, influence of postoperative radiotherapy on long-term survival is less clear. More effective systemic treatment to prevent distant metastasis should be investigated in future study to improve long-term survival.

PURPOSE: The purpose of this study was to examine the relationship among emotional intelligence, empathy and facilitative communication ability of psychiatric nurses. METHODS: Participants were 173 conveniently selected psychiatric nurses from 10 hospitals in Korea. Data were collected from June to September, 2015 through self-reported questionnaires. RESULTS: Facilitative communication ability was significantly different depending on educational level (t=6.06, p=.003). There were significant positive correlations between emotional intelligence and facilitative communication ability (r=.61, p<.001), and also between empathy and facilitative communication ability (r=.63, p<.001). In the multiple regression, except for education level, emotional intelligence (β=.17, p=.003) and empathy (β=.21, p=.000) explained 38.2% of the variance in facilitative communication ability. CONCLUSION: These findings indicate that emotional intelligence and empathy are important factors in psychiatric nurses' facilitative communication ability. Accordingly, to improve the facilitative communication ability of psychiatric nurses, educational programs based on development of emotional intelligence and empathy are necessary.

PURPOSE: This study aimed to investigate job satisfaction, organizational commitment and turnover intention among male nurses in South Korea. METHODS: Data were collected in May, 2013 and a total of 150 male hospital nurses participated in this study. Job satisfaction, organizational commitment and turnover intention were measured using a structured questionnaire. Collected data were analyzed using SPSS/WIN 20.0 for windows. RESULTS: There were statistically significant correlations between job satisfaction and organizational commitment (r=.74, p<.001), job satisfaction and turnover intention (r=-.56, p<.001), and organizational commitment and turnover intention (r=-.69, p< .001). There was a statistically significant difference in job satisfaction of participants according to education, work unit, and salary. Organizational commitment showed significant difference according to age, education, work unit, and salary. Turnover intention was significantly different according to duration of employment in the hospital, and salary. The most influential factor for turnover intention was organizational commitment (beta=-.69, p<.001). This factor accounted for 47.8% of the variance in turnover intention. CONCLUSION: The results of this study indicate that to reduce turnover intention for men in nursing, it is necessary to increase job satisfaction, and organizational commitment.

PURPOSE: To evaluate the results of radiation management on recurrence, survival and prognostic factors of patients with nasopharyngeal cancer. MATERIALS AND METHODS: Forty-nine patients, treated for nasopharyngeal cancer by radiotherapy between January 1984 and June 2000, were retrospectively studied. All patients were followed up for at least 2.5 years. Their median age was 52 years (range 17~78). The histological types were 21 squamous cell carcinoma, 25 undifferentiated carcinoma, and 3 adenoid cystic carcinoma. The tumor stages were as follows: T1 in 14 patients, T2 in 24, T3 in 3, and T4 in 8, and N0 in 17 patients, N1 in 15, N2 in 4 and N3 in 13. Stages I, IIa, IIb ,III, IV and IVb were 4, 7, 12, 5, 8, and 13 patients respectively. Radiation doses of 58~70 Gy (median 68.7 Gy) were given to the nasopahryngeal and involved lymphatic areas and of 46~50 Gy to the uninvolved neck areas. RESULTS: The overall 5 and 10-year actuarial and disease free survival rates were 54.53% and 47%, and 55.7% and 45.3%, respectively. The overall five-year survival rates were 100% in stage I , 80% in stage IIa, 59.5% in stage IIIb, 40% in stage III, and 42.2% in stage IV tumors. Twenty-three patients failed either loco-regionally or distantly. Incidences of local failure, regional failure and distant metastasis for the first failure were 20.4%, 8.2% and 20.4%, respectively. Local recurrences were 4.3% in T1, 12.5% in T2, 0% in T3, and 62.5% in T4 lesions. Distant metastasis was seen in 41.2% of N2-3 lesions. Fifty percent of local recurrence appeared within 2 years of treatment at the primary lesion, whereas 70% of distant metastasis appeared within 2 years following treatment. Young age, female, early T stage, N0 stage, and poorly differentiated carcinoma were all related with good survival. However only stage showed statistically significance. CONCLUSION: Based on the results of this study, radiation therapy to nasopharyngeal cancer showed high local recurrence in T4 and increased metastasis in N2-3 lesions. To improve local failure, further radiation doses, such as stereotactic radiation or IMRT radiation, are necessary especially in T4 lesions. The high incidence of distant metastasis in positive lymph node patients, indicates that combined radiation and effective chemotherapeutic agents with appropriated schedule are necessary.
