The purpose of this study is to investigate relationships among gifted students' perceived parental behavior of their parents, self-esteem, and emotional intelligence. The sample includes 91 6th-11th grade gifted students enrolled at a gifted program in a University. The surveys, administered in March, 2012, assess self-esteem, emotional intelligence, and the parental behavior of the parents of gifted students. Data were collected and analyzed by the researchers, using SPSS 18.0. The results are as follows: 1) Each of the 10 item's mean score is over 4.0, and the total mean scores on self-esteem is 4.36 out of 5 (SD=.546), showing positive responses. 2) The mean scores of two aspects of emotional intelligence were close to 4, showing positive perception. 3) The mean scores on perception of a father's and a mother's behavior are at 3.89 and 4.10, respectively; the three factors of perception among fathers (care, trust, and respect) are close to 4.0, while care (3.57) was somewhat low; the perception among mothers is at 4.31 (care), 4.20 (lesson), 4.01 (respect), and 3.96 (trust), showing statistical differences between fathers and mothers. 4) The correlation existed between self-esteem and emotional intelligence, between self-esteem and the four aspects of parental behavior, and between emotional intelligence and parental behavior. 5) Regression analyses showed that respect (${\beta}$=.422, p<.001) among fathers, and trust (${\beta}$=.450, p<.001) among mothers affected students' self-esteem; lessons (${\beta}$=.414, p<.001) and trust (${\beta}$=.280, p<.01) among fathers and lessons (${\beta}$=.450, p<.001) and respect (${\beta}$=.331, p<.01) among mothers affected students' emotional intelligence. The implication of this study, limitation, and future study ideas are suggested at the end of this paper.

Many previously described nuclear medicine procedures to assess glomerular filtration rate have some problems because numerous blood sample is to be taken and they don't measure each separate renal function. Gates described isotopic method for the measurement of global and unilateral GFR based on the fractional renal uptake of $^{99m}Tc$-DTPA 2 to 3 minutes after its intravenous injection. We evaluated GFR using $^{99m}Tc$-DTPA in 57 people according to Gates method and compared with creatinine clearance. A good correlation was observed between creatinine clearance and GFR calculated by Gates' formula with an r value of 0.9(P<0.05). And also the relationship between parameters of $^{99m}Tc$-DTPA renal scan images and GFR was taken. They were significantly correlated with GFR calculated by Gates' formula : r value 0.66 between relative intensity of peak renal to peak aortic activity(pK/pA) and GFR, -0.42 between time between aortic and kidney peak(A-K) and GFR and -0.48 between parenchymal renal activity at 25 min compared to peak kidney activity(25K/pK) and GFR. In conclusion, the determination of GFR according to the Gates' formula shows good and reproducible of GFR with rapidity and simplicity. And the parameters from the renal scan images can use to estimate the renal function.

The purpose of this study was to investigate if there were a significant difference between cephalometric measurements of mandibular position derived from a centric occlusion tracing compared to those of a converted centric relation tracing in the Class III malocclusion. The sample consisted of 25 Class III malocclusion and 25 normal occlusion persons who had no orthodontic treatment. The records included an lateral cephalometrics in centric occlusion, centric relation and centric occlusion bite registration and diagnostic casts mounted on the SAM II articulator in CR. The amount of CR-CO discrepancy of condyle was recorded using a MPI(Mandibular Position Indicator, MPI $200^{(R)}$, Great Lakes Orthodontics, USA). The conversion of the CO cephalogram to CR using the MPI readings was performed on the Conversion work sheet. Measures of mandibular position were chosen for the purpose of this study. The comparison of the difference between CO and CR cephalometric measurements in the normal occlusion and Class III malocclusion group were studied. The results were as follows: 1. In the features of CR-CO discrepancy of the condyle, the condyle was displaced posterior and inferior when the teeth were in centric occlusion. The horizontal component(${\Delta}X$) in Class HI malocclusion group was greater than the vertical component(${\Delta}Z$) and also greater than the horizontal component(${\Delta}X$) in normal occlusion group. There was no statistically significant correlation between MPI measurements and the groups of normal occlusion and Class III malocclusion group. 2. In the comparison of the cephalometric measurements in each group, Normal occlusion group showed significant difference in measurements such as ANB, Facial angle, Facial convexity and ODI. Class HI malocclusion group showed significant difference in measurements such as ANB, Facial angle, Facial convexity, ODI, SNB, APDI, L1-FP and it had more significance than the normal occlusion group. 3. The Value of cephalometric measurements was significantly different between CO and CR but there were no differences between the groups of normal occlusion and Class III malocclusion. The results of this study suggest that if the discrepancies are greater than the amount of normal displacement from clinically captured centric relation, centric relation should be considered as the starting point for proper diagnosis and treatment planning.

Objectives : The Illness Intrusiveness Rating Scale (IIRS) is a well-validated self-report instrument for assessing negative impact of chronic illness and/or adverse effects of its treatment on everyday life domains. Although extensive literature probed its psychometric properties in medical illness, little attention was paid for its validity for psychiatric population. This study aimed to test factorial structure of the Korean Version of the IIRS (IIRS-K) in a consecutive sample of psychiatric outpatients. Methods : Data set of 307 first-visit patients of psychiatric clinic at Guri Hanyang univ. Hospital were used. Exploratory and confirmatory factor analysis, internal consistency were tested in IIRS-K. We also checked Spearman's correlation analysis between IIRS-K, Zung's self-report anxiety scale and Zung's self-report depression scale. Results : 76.9% of the patients were with anxiety disorder and depressive disorder. The principal component factor analysis of the IIRS-K extracted three-factor structure accounted for 63.2% of total variance that was contextually similar to the original English version. This three-factor solution showed the best fit when tested confirmatory factor analysis compared to the original IIRS, two-factor model of IIRS-K suggested from medical outpatients, and one-factor solution. The IIRS-K also showed good internal consistency (Cronbach's α=0.90) and good convergent validity with anxiety and depression scales. Conclusions : The IIRS-K showed the three-factor structure that was similar but not identical to original version. Overall, this study proved factorial validity of the IIRS-K and it can be used for Korean clinical population.

This study empirically examines the impact of SSM market entry on changes in market shares among retailing types. The data is monthly time-series data spanning over the period from January 2000 to December 2010, and the effect of SSM market entry on market shares of retailing types is analyzed by utilizing several key factors such as the number of new SSM monthly entrants, total number of SSMs, the proportion of new SSM entrant that is smaller than $165m^2$ to total new SSM entrants. According to the Korean Standard Industrial Classification codes, the retailing type is classified into 5 groups: department stores, retail sale in other non-specialized large stores(big marts), supermarkets, convenience stores, and retail sale in other non-specialized stores with food or beverages predominating (others). The market shares of retailing types are calculated by the ratio of each retailing type monthly sales to total monthly retailing sales in which total retailing sales is the sum of each retailing type sales. The empirical model controls for the size effects with the number of monthly employees for each retailing type and the macroeconomic effects with M2. The empirical model employed in this study is as follows; $$MS_i=f(NewSSM,\;CumSSM,\;employ_i,\;under165,\;M2)$$ where $MS_i$ is the market share of each retailing type (department stores, big marts), supermarkets, convenience stores, and others), NewSSM is the number of new SSM monthly entrants, CumSSM is total number of SSMs, $employ_i$ is the number of monthly employees for each retailing type, and under165 is the proportion of new SSM entrant that is smaller than $165m^2$ to total new SSM entrants. The correlation among these variables are reported in
