OBJECTIVE: Diurnal preference is an attribute reflecting whether people are alert and preferring to be active either early or late in the day. It also referred to as chronotype or morningness-eveningness trait. The PER3 genes have been known to influence diurnal preference. In this study, we have investigated the associations between the PER3 gene polymorphisms and diurnal preference in a healthy young population, controlling for the social and environmental confounding factors. METHODS: The participants in this experiment included 299 unrelated medical college students (M=191, F=108), with a mean age of 22.9 years. Diurnal preference was measured by a single administration of the 13-item Composite Scale for Morningness (CSM). Genotyping of the PER3 VNTR (rs57875989) was performed using polymerase chain reaction. A two-tailed alpha of 0.05 was chosen. RESULTS: The mean+/-SD score on the CSM scale for all subjects was 31.90+/-6.39. There was no significant difference in total CSM score between gender groups, although females showed a trend towards higher morningness score. Although PER3 5R/5R showed the tendency towards high CSM scores, there were no significant differences on CSM scores among genotypes and allele status of PER3 VNTR (rs57875989). CONCLUSIONS: We could not confirm that the PER3 VNTR is associated with diurnal preference in a Korean healthy young population. The future studies need to investigate the association between diurnal preference and other polymorphisms of PER3 gene in larger sample of Korean young healthy population.

4.The Relationship of Communication Competence, Professional Self-Concept and Stress in Clinical Practice of Nursing Students.
Journal of Korean Academic Society of Nursing Education 2016;22(4):452-461
PURPOSE: This study was conducted to investigate the relationships among communication competence, professional self-concept, and stress in clinical practice of nursing students. METHODS: The study participants were 308 senior year nursing students in D city and K province. Collected data were analyzed using t-tests, analysis of variance, Pearson's correlation coefficient, and stepwise multiple regression with the SPSS Version 20.0. RESULTS: There were significant differences in participants' stress of clinical practice based on their level of satisfaction on clinical practice, self-confidence of nursing and difficulty with relationships in clinical practice. A negative correlation was detected between stress in clinical practice and the professional self-concept of nursing students. Significant predictors of the perceived stress of clinical practice were satisfaction in clinical practice and pride in nursing. These accounted for 18% of the perceived stress of clinical practice in a regression model. CONCLUSION: The results may serve as basic data in support of the need to the develop effective systematic stress management programs and clinical training courses in order to attenuate the stress experienced during clinical practice of nursing students.

BACKGROUND: This study compared the clinical and radiological outcomes of the single calcar screw plate and Polarus nail techniques for the treatment of the proximal humerus fractures. METHODS: Seventy-two patients diagnosed with displaced proximal humerus fracture were enrolled for the study. Of these, 50 patients underwent the locking plate surgery with a single calcar screw (plate group), whereas 22 patients underwent the Polarus nail surgery (nail group). The plate group was further divided into plate 1 group (with medial support), and plate 2 group (without medial support). The radiological and functional results of both groups were compared to the nail group. RESULTS: The α angle 1 year after surgery was significantly different between plate 1 and plate 2, and plate 2 and nail groups (p=0.041, p=0.043, respectively). The ratio that does not satisfy the reference value of γ angle was 2.8% in plate 1, 7.1% in plate 2 and 22.7% in nail group (p=0.007); there was a significant difference between plate 1 and nail group, and plate 2 and nail group (p=0.014, p=0.033, respectively). CONCLUSIONS: No significant differences were observed in the clinical results between locking plate and Polarus nail. However, in the plate 2 group and nail group, the rate of failure to maintain reduction during the 1-year period after surgery was statistically and significantly higher than the plate 1 group (level of evidence: level IV, case series, treatment study).

A 62-year-old woman without vascular risk factors presented with left-sided weakness and numbness.
Magnetic resonance imaging (MRI) brain depicted acute right hemispheric infarcts in the cortical and
subcortical white matter. Initial MR angiography (MRA) showed large thrombus at the right carotid
bifurcation. Valvular atrial fibrillation (vAF) with severe tricuspid regurgitation (TR) was found on
two-dimensional echocardiography. Serial follow-up computed tomography angiography (CTA) or
MRA at 3, 9, and 15 days after anticoagulation alone showed complete resolution of the thrombus
with no neurological deterioration. Our case suggests that prompt institution of anticoagulantion alone
may result in radiologic resolution of the thrombus with improvement in patient’s clinical status.

PURPOSE: In this study, we aimed to evaluate whether nonalcoholic fatty liver disease (NAFLD) was associated with the presence and morphology of coronary atherosclerotic plaques shown by multidetector computed tomography (MDCT) in asymptomatic subjects without a history of cardiovascular disease. MATERIALS AND METHODS: We retrospectively enrolled 772 consecutive South Korean individuals who had undergone both dualsource 64-slice MDCT coronary angiography and hepatic ultrasonography during general routine health evaluations. The MDCT studies were assessed for the presence, morphology (calcified, mixed, and non-calcified), and severity of coronary plaques. RESULTS: Coronary atherosclerotic plaques were detected in 316 subjects (40.9%) by MDCT, and NAFLD was found in 346 subjects (44.8%) by hepatic ultrasonography. Subjects with NAFLD had higher prevalences of all types of atherosclerotic plaque and non-calcified, mixed, and calcified plaques than the subjects without NAFLD. However, the prevalence of significant stenosis did not differ between groups. After adjusting for age, smoking status, diabetes mellitus, hypertension, dyslipidemia, and metabolic syndrome, NAFLD remained a significant predictor for all types of coronary atherosclerotic plaque [odds ratio (OR): 1.48; 95% confidence interval (CI): 1.05-2.08; p=0.025] in binary logistic analysis, as well as for calcified plaques (OR: 1.70; 95% CI: 1.07-2.70; p=0.025) in multinomial regression analysis. CONCLUSION: Our study demonstrated that NAFLD was significantly associated with the presence and the calcified morphology of coronary atherosclerotic plaques detected by MDCT. Further prospective clinical studies are needed to clarify the exact physiopathologic role of NAFLD in coronary atherosclerosis.

OBJECTIVE: This study was done to evaluate the risk factors associated with recurrence after first-ever stroke. METHOD: We retrospectively studied 256 first-ever stroke patients treated in Dong-Eui hospital from March 1997 to February 1998. Telephone or out-patient interviews were performed with these patients regarding stroke recurrence and treatment for hypertension and diabetes mellitus. These were divided into two groups, those with recurrence and those without. Evaluated risk factors for stroke recurrence were the following: history of diabetes mellitus, hypertension, heart disease, smoking, alcohol drinking, and transient ischemic attack; clinical findings at admission of hypertension, diabetes mellitus, hyperlipidemia, heart disease, type and location of stroke; treatment compliance for diabetes mellitus and hypertension after discharge. RESULTS: The recurrence rate after first-ever stroke was 12.9%. In univariate analysis, significant risk factors for stroke recurrence were history of smoking, clinical findings at admission of diabetes mellitus, atrial fibrillation, ischemic heart disease, and non-compliance with therapy for diabetes mellitus and hypertension after discharge (p<0.05). In multivariate analysis, significant risk factors for stroke recurrence were atrial fibrillation at admission (odds ratio=3.43) and non-compliance with therapy for hypertension after discharge (odds ratio=7.51)(p<0.05). CONCLUSION: History of smoking, clinical findings at admission of diabetes mellitus, atrial fibrillation, ischemic heart disease, and non-compliance with therapy for diabetes mellitus and hypertension after discharge are considered to be important factors for recurrence of stroke. So treatment and education for those factors associated with stroke recurrence are needed during rehabilitation program.

OBJECTIVE: Fracture has been reported as one of complicated problems in stroke patients. The purpose of this study is to provide epidemiologic data on fractures in stroke patients and investigate the specific feature of these fractures. METHOD: Stroke patients treated in Dong-Eui hospital due to fracture after stroke from March 1990 to March 1999 were enrolled in this study, and the retrospective study of fracture was performed on these patients. RESULTS: Subjects were 73 fracture patients with history of previous stroke. There were 50 patients with ischemic stroke and 23 patients with hemorrhagic stroke. And 35 patients were right hemiplegia, 38 patients were left hemiplegia. In this study, the causes of fracture were slip (63 cases, 86.3%), fall (6 cases, 8.2%), range of motion exercise (3 cases, 4.1%), and crushing injury (1 case, 1.4%). The frequency of fracture in patients who walk independently or with minimal to moderate assist was higher than in patients who walk with maximal assist or were bed-ridden state. In 65 patients, the fracture occured on the same side of hemiplegia. The distribution of fracture site was femur (45 cases, 61.6%), humerus (12 cases, 16.4%), and radius (3 cases) in the order of frequency. The interval between stroke and occurrence of fracture were less than 6 months in 34 cases (46.6%), 6 months to 1 year in 10 cases (13.7%), 1 to 2 years in 13 cases (17.8%), and 2 to 20 years in 16 cases (21.9%). CONCLUSION: As with our study, the fracture in stroke patient tend to occur within the first year after a stroke as a result of slip and the most frequently affected site is femur of hemiplegic side.
