Objective : To assess the relationship and prevalence rate among hypertension, dyslipidemia and the four commenest anthropometric measurements for obesity(body mass index(BMI), waist-hip ratio(WHR), waist circumference(WC) and body fat) in Korean adults. Methods : We studied the cross-sectional association of the anthropometric indicies and hypertension, dyslipidemia in 70 Korean adults. Hypertension was defined as blood pressure ${\ge}160/95$mmHg and classification of JNC IV, Dyslipidemia were defined as total cholesterol ${\ge}200$ mg/dl, HDL-cholesterol ${le}35$ mg/dl, LDL-cholesterol ${\ge}160$ mg/dl, triglyceride ${\ge}200$ mg/dl. Infromations on life-style factors were obtained from personal interview. Results : BMI and WHR, BMI and WC, BMI and Fat(%), WHR and WC, WC and Fat(%) had high partial correlation coefficients after age adjustment. BMI and Systolic Blood Pressure had r=0.385 coefficients, WHR and HDL-cholesterol had r=-0.360 coefficients. All four anthropomtric indicies and hypertenstion groups by JNC IV classsification had signifiant differences in women, but only fat(%) and hypertension had significant difference in men. In women, in the relationship of four anthropomtric indicies and serum lipids, total cholesterol ${\ge}200$ mg/dl group with fat(%) had a signifiant difference for normal cholesterol group, and also the group of HDL-cholesterol ${\le}$ mg/dl with WC had significance. But in men, there were no significant differences in all anthropomtric indicies and serum lipids groups. Conclusions : Korean women are more significant than Korean men in the relationship between anthropometric indicies and serum lipids, or blood pressure. But this study's samples are small, so the results are some different with results of other studies. We should study more specifically about anthropometric indicies and serum lipids, anthropometric indicies and blood pressure with many samples.

In multivariate analysis, absorbance spectrum is measured over a band of wavelengths. One does not often pay attention to the size of this wavelength band. However, it is desirable that spectrum is measured at only necessary wavelengths as long as the acceptable accuracy of prediction can be met. In this paper, the method of selecting an optimal band of wavelengths based on the loading vector analysis was proposed and applied for determining total protein in human serum using near-infrared transmission spectroscopy and PLSR. Loading vectors in the full spectrum PLSR were used as reference in selecting wavelengths, but only the first loading vector was used since it explains the spectrum best. Absorbance spectra of sera from 97 outpatients were measured at 1530∼1850 nm with an interval of 2 nm. Total protein concentrations of sera were ranged from 5.1 to 7.7 g/㎗. Spectra were measured by Cary 5E spectrophotometer (Varian, Australia). Serum in the 5 mm-pathlength cuvette was put in the sample beam and air in the reference beam. Full spectrum PLSR was applied to determine total protein from sera. Next, the wavelength region of 1672∼1754 nm was selected based on the first loading vector analysis. Standard Error of Cross Validation (SECV) of full spectrum (1530∼l850 nm) PLSR and selected wavelength PLSR (1672∼1754 nm) was respectively 0.28 and 0.27 g/㎗. The prediction accuracy between the two bands was equal. Wavelength selection based on loading vector in PLSR seemed to be simple and robust in comparison to other methods based on correlation plot, regression vector and genetic algorithm. As a reference of wavelength selection for PLSR, the loading vector has the advantage over the correlation plot since the former is based on multivariate model whereas the latter, on univariate model. Wavelength selection by the first loading vector analysis requires shorter computation time than that by genetic algorithm and needs not smoothing.

Purpose: The aim of this study was to identify the status of performance on standard precautions among nursing students and to examine the mediating effects of internal health locus of control on the relationship between awareness and performance on standard precautions of hospital-acquired infection control. Methods: The participants in this study were 134 nursing students. The measurements included a standard precautions awareness and performance scale, and a multidimensional health locus of control scale. Data were analyzed using independent t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficient, and simple and multiple regression techniques. Mediation analysis was performed by the Baron and Kenny's method and Sobel test. Results: The mean score of standard awareness, standard performance, and internal health locus of control about standard precaution were $174.30{\pm}9.08$; $169.48{\pm}12.04$; and $20.43{\pm}2.82$; respectively. There was a positive correlation between standard awareness and performance (r=.414, p<.001). Also, standard awareness was significantly correlated with internal health locus of control (r=.413, p=.014). Internal health locus of control showed partial mediating effects in the relationship between awareness and performance. Conclusion: The results indicate a need to improve the internal health locus of control of nursing students. Therefore, an internal health locus of control improvement program should improve performance on standard precautions for patients and themselves.

NIRS uses reflectance signals resulting from bending and stretching vibrations in chemical bonds between carbon, nitrogen, hydrogen, sulfur and oxygen. These reflectance signals are used to measure the concentration of major chemical composition and other descriptors of homogenized and freeze-dried whole broiler carcasses. Six strains of chicken were analyzed and the NIRS model predictions compared to reference data. The results of this comparison indicate that NIRS is a rapid tool for predicting dry matter (DM), fat, crude protein (CP) and ash content in the broiler carcass. Males and females of six commercial strain crosses of broiler chicken (Gallus domesticus) were used in this study (6$\times$2 factorial design). Each strain was grown to 16 weeks of age, and duplicate serial samples were taken for body composition analysis. Each whole carcass was pressure-cooked, homogenized, and a representative sample was freeze-dried. Body composition determined as follows: DM by oven dried method at 105$^{\circ}C$ for 3 hours, fat by Mojonnier diethyl ether extraction, CP by measuring nitrogen content using an auto-analyzer with Kjeldhal digest and ash by combustion in a muffle furnace for 24 hour at 55$0^{\circ}C$. These homogenized and freeze-dried carcass samples were then scanned with a Foss NIR Systems 6500 visible-NIR spectrophotometer (400-2500nm) (Foss NIR Systems, Silver Spring, MD., US) using Infra-Soft-International, ISI, WinISl software (ISI, Port Matilda, US). The NIRS spectra were analyzed using principal component (PC) analysis. This data was corrected for scatter using standard normal “Variate” and “Detrend” technique. The accuracy of the NIRS calibration equations developed using Partial Least Squares (PLS) for predicting major chemical composition and carcass descriptors- such as body mass (BM), bird dry matter and moisture content was tested using cross validation. Discrimination analysis was also used for sex and strain identification. According to Dr John Shenk, the creator of the ISI software, the calibration equations with the correlation coefficient, $R^2$, between reference data and NIRS predicted results of above 0.90 is excellent and between 0.70 to 0.89 is a good quantifying guideline. The excellent calibration equations for DM ($R^2$= 0.99), fat (0.98) and CP (0.92) and a good quantifying guideline equation for ash (0.80) were developed in this study. The results of cross validation statistics for carcass descriptors, body composition using reference methods, inter-correlation between carcass descriptors and NIRS calibration, and the results of discrimination analysis for sex and strain identification will also be presented in the poster. The NIRS predicted daily gain and calculated daily gain from this experiment, and true daily gain (using data from another experiment with closely related broiler chicken from each of the six strains) will also be discussed in the paper.

Objectives In this study, the authors evaluated the correlation between levels of serum lipid, homocysteine, and folate with volumes of hippocampus, amygdala, corpus callosum, and in patients with amnestic mild cognitive impairment (aMCI) or Alzheimer's disease (AD) type. Methods The study recruited patients who visited the dementia clinic of Haeundae Paik Hospital in Korea between March 2010 and June 2014. Among those, patients who had taken the neurocognitive test, brain magnetic resonance imaing, tests for serum lipid, homocysteine, folate, and apolipoprotein E (APOE) genotyping and diagnosed with aMCI or AD were included for analysis. Bilateral hippocampus, entorhinal cortex, amygdala and corpus callosum were selected for region of interest (ROI). The cross-sectional relationships between serum lipid, homocysteine, folate and ROI were assessed by partial correlation analysis and multiple linear regression analysis. Results In patients with aMCI, old age (> 80) and APOE ${\varepsilon}4$ carrier were associated with AD [odds ration (OR) : 12.80 ; 95% confidence interval (CI) : 2.25-72.98 and OR : 4.48 ; 95% CI : 1.58-12.67, respectively]. In patients with aMCI or AD, volumes and thickness of ROI were inversely correlated with levels of serum lipid and homocysteine. In multiple linear regression analyses, higher total cholesterol level was related to lower left, right hippocampus volume and left amygdala volume ; higher low-density lipoprotein cholesterol was related to lower right entorhinal cortex thickness ; higher homocysteine level was related to lower corpus callosum volume. Conclusions Higher serum lipid and homocysteine levels are associated with decreased volume of hippocampus, amygdala, corpus callosum and entorhinal cortex thickness in patients with aMCI or AD. These findings suggest that serum lipid and homocysteine levels are associated with AD as a modifiable risk factor.

Purpose: The purpose of this study was to examine the mediating effect of regimen distress in the relationship between medication adherence and glycemic control in men with type 2 diabetes. Methods: A total of 116 patients with type 2 diabetes was recruited for the cross-sectional survey design. Data were analyzed using descriptive statistics, independent t-test, ANOVA, Pearson's correlation coefficient, and multiple regression using Baron and Kenny steps for mediation. Results: The mean score for medication adherence was 6.32, and the mean glycemic control level (HbA1c) was 7.47%. The mean score was 2.37 for regimen distress. There were significant correlations among medication adherence, regimen distress, and HbA1c. Regimen distress had a partial mediating effect (${\beta}$=.22, p=.005) in the relationship between medication adherence and HbA1c (Sobel test: Z=2.47, p=.013). Conclusion: Regimen distress was found to be associated with glycemic control in men with type 2 diabetes. Based on the findings of this study, nursing intervention programs focusing on decreasing regimen distress are highly recommended to improve level of glycemic control in patients with type 2 diabetes.

Purpose: The diagnosis of pelvic fractures pattern has become to be essential in the decision making of treatment modality and reducing morbidity and mortality in multiple trauma patients. Sacroiliac joint (SIJ) disruption can cause life-threatening massive arterial bleeding. This study aimed to determine a method of predicting the prognosis and treatment direction with pelvis X-ray alone in the emergency room. We investigated whether SIJ disruption can be used alone as a poor prognostic factor. Methods: We analyzed the medical records and radiologic examination results of 167 patients with pelvic fractures from January 1, 2015 to December 31, 2016 retrospectively. Patients with pathologic fractures, thoraco-abdominal bleeding, and acetabulum fractures and pediatric patients (n=63) were excluded. Factors related to the clinical manifestations and treatments, such as transfusion and surgery, were statistically compared. Results: The cross-sectional analysis showed that there was no correlation between SIJ injury and sex; there were statistically significant relationships between occurrences of shock, conjoined fractures, transfusion, and surgeries. The hospitalization period and partial thromboplastin time and prothrombin time values increased. The logistic regression analysis showed that when an SIJ injury occurred, blood transfusion and hypotension possibilities increased. Conclusions: When pelvic fractures occur near the SIJ, blood transfusion and shock possibilities increase. Physicians must be aware of the high severity and poor prognosis of such fractures when these are diagnosed in the emergency room. And furthermore, the physician has to predict and prepare the intensive care and multidisciplinary approaches.
