Objective : To translate Center for Epidemiologic Studies Depression Scale (CES-D) into North Korean language and to examine its reliability and validity Methods : North Korean defectors (n=207) recruited from the call center for North Korean defectors participated. Psychiatrists and psychiatric residents interviewed the participants and made the psychiatric diagnoses. Subsequently, the participants completed the CES-D, Impact of Event-Scale-Revised-North Korea (IES-R-NK), Alcohol Use Disorders Identification Test-North Korea (AUDIT-NK), and Brief Psychological State Inventory for North Korean Refugees (BPSI-NKR) questionnaires. Of the original participants, 143 subjects participated in test-retest reliability study after one week. Results : Cronbach's alpha coefficient of CES-D-NK was superior in both males (0.91) and females (0.93). The test-retest correlation coefficient was high (males, 0.64 ; femals, 0.79). Good convergent validity was evident by significant correlations with IER-R-NK, BPSI-NKR-Depression and BPSI-NKR-PTSD, respectively. CES-D-NK had no or weak correlations with AUDIT-NK and BPSI-NKR-Alcohol, showing its discriminant validity. Conclusion : CES-D-NK could be a reliable and valid tool for screening and assessing depressive symptoms of North Korean defectors.

This paper proposes illumination-efficient iris image capturing method. face capture method for extraction of iris pattern with one high resolution camera needs a large scale near infrared illumination. we replace high-resolution camera with co-optic-axial combination between wide view camera and narrow view camera. because this method needs small scale illumination that illuminate only narrow camera viewing angle, we can capture iris pattern image with small scale near infrared illumination.

Objectives: This study aimed to compare the utility of the Psychoeducational Profile-Revised (PEP-R), Korean Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (K-WPPSI-IV), and Vineland Adaptive Behavior Scale, Second Edition (VABS-II) for evaluating developmental disabilities (DD) in preschool children. Additionally, we examined the correlations between the PEP-R, K-WPPSI-IV, and VABS-II. Methods: A total of 164 children aged 37-84 months were assessed. Children's development was evaluated using the PEP-R, K-WPPSI-IV, VABS-II, Preschool Receptive-Expressive Language Scale, and Korean Childhood Autism Rating Scale, Second Edition. Results: Of the 164 children, 103 had typical development (TD) and 61 had DD. The mean of the PEP-R Developmental Quotient (DQ), K-WPPSI-IV Full-Scale Intelligence Quotient (FSIQ), and VABS-II Adaptive Behavior Composite (ABC) scores were significantly higher in the TD group than in the DD group (p<0.001). The estimated area under the curve of the PEP-R DQ, K-WPPSI-IV FSIQ, and VABS-II ABC scores was 0.953 (95% confidence interval [CI]=0.915-0.992), 0.955 (95% CI=0.914-0.996), and 0.961 (95% CI=0.932-0.991), respectively, which did not indicate a statistically significant difference. The PEP-R DQ scores were positively correlated with the K-WPPSI-IV FSIQ (r=0.90, p<0.001) and VABS-II ABC scores (r=0.84, p<0.001). A strong correlation was observed between the K-WPPSI-IV FSIQ and VABS-II ABC scores (r=0.89, p<0.001). Conclusion: This study found that the PEP-R, K-WPPSI-IV, and VABS-II effectively distinguished DD from TD in preschool children, and no significant differences in utility were observed between them.

Since Au-Pt alloys have various atomic structures depending upon composition and annealing temperature, it is very interesting to investigate the electronic structures of alloys. We studied the changes of the electronic structure I the Au-Pt alloys by x-ray absorption near edge spectroscopy (XANES). Two kinds of Au-Pt alloy samples were prepared by arc melting methods and ion-beam-mixing technique. The Pt L2, 3-edge and Au L2, 3-edge X-ray absorption spectra (XPS) were measured with the electron yield mode detector at the 3C1 beam line of the Pohang Light Source (PLS). It was found that there was a substantial decrease in the area of the Pt L2, 3 white lines compared with that of pure Pt. The observed decrease in white line area was attributed to an increase in the number of pure Pt. The observed decrease in white line area was attributed to an increase in the number of 5d-electrons at the Pt site upon alloy formation. However, the Au L2, 3 edge spectra for Au-Pt alloys are all similar to that of pure Au. This implies that the 5d hole count of Au is not changed by alloy formation with Pt.

We witnessed the enhancement of mangetoresistance (MR) in La0.75Ca0.25MnO3 thin films grown on Si (100) substrates by RF magnetron sputtering. The films are polycrystalline with (100) and (110) orientations. The lattice constants of films are reduced as much as 0.9% compared to the one of the bulk sample, which proves that the compressive stress on films was imposed by Si sbustrate. It is found that the MR value (Δ$\rho$/$\rho$0) of films are 0.33, 0.29 and 0.27 under a magnetic field of 1.5T for each films with deposition temperature of $700^{\circ}C$, 75$0^{\circ}C$ and 80$0^{\circ}C$, respectively. The correlation between the MR values and lattice constants of films is discussed. It is concluded that the compressive stress on films cause the enhancement of MR values of thin films grown on Si (1000 substrates. Some mechanism of compressive stress induced by Si substrate is suggested.

Fitness center which was first introduced through hotel fitness has been disseminated into country over the years and these days it becomes a public sports facility that is available even in a small city. Fitness center usually requires a space more than 500 pyeong and even in a small fitness facility at least 200-300 pyung is in need. Also, complex structure including a space for preparing exercise and other subsidiary facility is necessary as well as various service areas to perform various exercise programs. In case of domestic fitness centers, however, proper standard and data required to compute the scale of each service area is not available due to the short of piling data. Therefore computing each space totally depends on an instinct decision of a designer or client, which may cause the fail of effective use of space. This paper aims to calculate appropriate use of space, that is, the over all space, equipment size, and movement line of each area as well as preference and frequence of use among areas is estimated in order to apply those data when computing appropriate estimation of scale.

Glass slides were chemically etched with sulfuric acid using five different methods. we investigated the effects of the chemical etching conditions on such properties as chemical composition, surface roughness, and the thermal stability of the glass. Sodium and carbon atoms in the surface of the glass are effectively eliminated by chemical etching with sulfuric acid. The glass slides were boiled for 30 min in 95% sulfuric acid and were depth profiled at room temperature with X-ray photoelectron spectroscopy (XPS), the Na ls signal was not detected in the detection limit of XPS. Surface morphology of the glass was very different depending on the concentration of sulfuric acid. The surface of the glass etched with 50% sulfuric acid was rougher than that of glass etched with 95% sulfuric acid. The sodium concentration of the glass boiled for 30 min in 95% sulfuric acid was nearly zero at the glass surface, and the sodium composition changed very little with annealing temperatures up to 35$0^{\circ}C$ in a vacuum environment. However the sulfur concentration at the glass surface due to the sulfuric acid increased with increasing temperature.

Purpose: This study was conducted to evaluate life satisfaction(LS) and to assess the factors that influence LS in senior center elderly people. Methods: The subjects were 253 elders who visited the Y city Senior Welfare Center between July 2006 and August 2006. Data were collected using structured questionnaires. The instruments were composed of Kang's Family Support Scale, Depression Scale by Sheikh & Yesavage, Laffery's Health Concept Scale, and LS scale by Choi. T-test, ANOVA, Duncan test, Pearson coefficients correlation and stepwise multiple regression were used to analyze the data using the SPSS Win 12.0 program. Results: The LS level showed a maximum score of 38 with a mean score of 23.23. The mean scores for depression, health perception and family support were 5.52(maximum score, 15), 77.46(maximum score, 112), 43.45(maximum score, 55) respectively. The LS were significantly correlated with health perception, depression and family support. Depression was the most powerful predictor of and it accounted for 42.0% of the total variance in LS. A combination of significance of eudaimonistic health perception and satisfaction with pocket money accounted for 47.2% in LS. Conclusion: Depression and health perception were identified as affecting variables for the LS. Based upon these results, nurses should help the aged to enhance their LS.
