It is very important to screen the elderly for nutritional risk, because nutritional status is a critical factor to maintain their health. Some nutrition checklists used in Korea for the elderly are from other countries. Reliability of those checklist in Korea is not studied enough. This survey was done for the elderly over 65-years-old who live in Hong-cheon, An-dong, Dam-yang and Yeon-gi in Korea (subject; summer: 146, winter: 145) to study the reliability of DETERMINE checklist which is adopted widely in Korea. Using the score of DETERMINE checklist, the elderly were divided as high, middle and low risk groups. For nutritional assessment for those elderly, dietary assessment using 24 recall, anthropometry, biochemical assessment and health condition were used. Results for the checklist showed that percentage below EAR for energy intake and protein intake in winter were higher in the high risk group than other groups. The intakes of phosphorus and iron and most vitamins were below the DRI. The percentage of subjects with intake below DRI was highest in the high risk group. Sensitivity, specificity, and positive predictive values using the DETERMINE were calculated using 6 point as a cut-off point. Subjects were divided into two groups by MAR (MAR < 0.75:undernutrition, MAR < 0.75 : normal). Sensitivity recorded 49.4% and 34.3%, specificity did 61.9% and 65.4 and Positive predictive value did 62.1% and 46.0% each for summer and winter. Results of screening using DETERMINE Checklist were not matched with dietary assessment but not with anthropometric and biochemical measurement. In conclusion DETERMINE 'Checklist' is shown be a good screening tool for finding out risk groups for dietary intake in the elderly, It needs to verify reliability and validity through large-scale survey.

This paper describes the development of Korean version of two widely used self-report measure of alexithymia-Schalling-Sifneos Personality Scale (SSPS) and Toronto Alexithymia Scale(TAS), and present the preliminary results of their reliability and validity tested to an Korean college student sample(N=206). TAS showed moderate to acceptable internal consistancy with 0.26 of mean item-total correlation and 0.754 of Cronbach's alpha coefficient, while those parameters for SSPS turned out inconsistent. However, results of test-retest reliability for both scale were excellent. Factor analysis revealed tow factors for TAS and three factors for SSPS ; the four-factor structure of TAS was quite congruent with previously known alexithymaia construct, while, again, SSPS showed intermixed factor structure. TAS scores correlated fairly well with somatization scores enough to get concurrent validity while SSPS scores did not. Overall, Korean version of TAS demonstrated well matched findings in terms of internal consistency and factorial validity with original and Spanish version of TAS. The results suggest that Korean version of TAS could be a useful and reliable tool for the measurement in Korean population.

Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean version of Person-Centered Practice Inventory-Staff (PCPI-S) for nurses. Methods: The English PCPI-S was translated into Korean with forward and backward translation. Data were collected from 338 nurses at one general hospital in Korea. Construct validity was evaluated with confirmatory factor analysis, convergent validity, and discriminant validity. Known-group validity was also evaluated. Cronbach's α was used to assess the reliability. Results: The PCPI-S Korean version consisted of 51 items in three areas: prerequisites, the care environment, and person-centered process. The comparative fit index (CFI) and values of person-centered care process were improved after engagement and having sympathetic presence items were combined as one component. The construct validity of PCPI-S Korean version was verified using four-factor structures (.05 < RMSEA < .10, AGFI > .70, CFI > .70, and AIC). The convergent validity and discriminant validity of the entire PCPI-S question were verified using a two-factor structures (AVE > .50, construct reliability > .70). There was an acceptable known-group validity with a significant correlation between the PCPI-S level and the degree of person-centered care awareness and education. Internal consistency was reliable with Cronbach's α .95. Conclusion: The Korean version of PCPI-S is valid and reliable. It can be used as a standardized Korean version of person-centered care measurement tool. Abbreviation: RMSEA = root mean square error of approximation; AGFI = adjusted goodness of fit index; AIC = Akaike information criterion; AVE = average variance extracted.

Objectives: This study validated the Vietnamese version of the Disaster Adaptation and Resilience Scale (DARS) for use in vulnerable communities in Vietnam. Methods: This was a cross-sectional study involving 595 adults from 2 identified communities. The original DARS assessment tool was translated, and the validity and reliability of the Vietnamese version of DARS (V-DARS) were assessed. The internal consistency of the overall scale and its subscales was evaluated using Cronbach's alpha and McDonald's omega reliability coefficients. Confirmatory factor analysis (CFA) was employed to evaluate its construct validity, building upon the factor structure identified in exploratory factor analysis (EFA). Construct validity was assessed based on convergent and discriminant validity. Results: Following the established criteria for EFA, 8 items were removed, resulting in a refined V-DARS structure comprising 35 items distributed across 5 distinct factors. Both alpha and omega reliability coefficients indicated strong internal consistency for the overall scale (α=0.963, ω=0.963) and for each of the 5 sub-scales (all>0.80). The CFA model also retained the 5-factor structure with 35 items. The model fit indices showed acceptable values (RMSEA: 0.072; CFI: 0.912; TLI: 0.904; chi-square test: <0.01). Additionally, the convergent and discriminant validity of the V-DARS were deemed appropriate and satisfactory for explaining the measurement structure. Conclusions: Our findings suggest that the V-DARS is a valid and reliable scale for use within vulnerable communities in Vietnam to assess adaptive responses to natural disasters. It may also be considered for use in other populations.

Wii^® balance board (WBB) is a device that can measure and record body sway. This study was conducted to evaluate the reliability of WBB in small sized dog as inexpensive, portable and convenient tool. The center of pressure path length (CPPL) and 95% confidence ellipse area (Area 95) were evaluated with only two plates of WBB. The parameters were evaluated between no load (0 kg) and mass group (0.25-4 kg on each one plate). 23 dogs (2.3-7.3 kg) were evaluated for with hindlimb standing for 10 seconds. The mass group showed a significant value in comparison to the no load during the measurement. And intra-class correlation coefficients (ICCs) between CPPL and Area 95 revealed very high both mass and dog group. In the evaluation of medial patellar luxation (MPL) as a diagnostic tool, 80 dogs with MPL and 23 non-affected dogs were used. In studies of CPPL and Area 95, significant differences were found between non-affected and MPL groups for 10 and 30 seconds, respectively. The WBB can be used as a valid tool for evaluating hind limb standing balance and can be useful as an objective tool to present clinical results in small sized dog with MPL.

Objectives: This exploratory trial evaluated the possibility of quantitatively measuring several aspects during the "abdominal examination" of traditional Korean medicine. The main results of this study will be used to develop a new diagnostic device for abdominal examinations. Methods: Fifteen healthy volunteers were recruited for this study. Three certified Korean medical doctors assessed the existence of pressure pain, the elasticity of the abdominal muscle, and the tonus at CV12 as gold standards. Then, 2 well-trained investigators measured the pressure pain threshold (PPT), the indentation depth of a bar, and repelling force by pressing CV12. Each investigator measured the above 3 variables 2 times at 1 min intervals using a modified digital algometer. Reliability and validity tests of the 3 variables were performed. Results: There were statistically significant coefficients of intraclass correlation on the 3 variables both between and within the investigators (P<0.001). Also, PPT and repelling force showed statistically significant high sensitivity and specificity in a ROC curve. However, the indentation depth of the bar presented relatively low sensitivity. Conclusions: This new diagnostic method using a modified digital algometer could be a useful tool for quantitative measurement in "abdominal examinations". However, future rigorous clinical studies with a large population will be needed for the verification of its usefulness.

Purpose: To study inter- and intra-observer reliabilities of computerized measurements of the angular parameters of hallux valgus deformity, using two different kinds of software tools for angle measurement on the digital radiography. Materials and Methods: On 35 digital radiographies of standing foot anteroposterior view of hallux valgus, two observers (A, B) independently measured hallux valgus angle (HVA) and 1-2 intermetatarsal angle ($IMA_{1-2}$) twice, using two methods. In method I, an angle was determined from duplicated lines to longitudinal axes made for bisecting line on the target bones with software tool. In method II, an angle was calculated automatically and directly from bisecting lines (longitudinal axes) made on the target bones. We compared two methods using paired t-test to determine significance of differences. Inter- and intraobserver reliabilities were evaluated using the intraclass correlation coefficients (ICC). Results: There were no significant differences between measurements of method I and II for each observer (p>0.05) and intraobserver reliability were good. (ICC>0.9) Inter-observer reliability for method I and II was good of the HVA (ICCs, 0.912 and 0.905) and moderate of the $IMA_{1-2}$ (ICCs, 0.505 and 0.537). There were interobserver differences in HVA of method I and II. Conclusion: No significant difference was found statistically between measurements of method I and II. Both methods I and II would be acceptable to measure angular parameters of hallux valgus deformity.
