This study aimed to develop the short-form of age-friendly scale which was suitable for the Korean cities and to examine the validity. To develop the scale, WHO and Seoul welfare foundation's age-friendly city guide were compared and analyzed. The data for this study were collected on people aged over 55 years old living in Seoul. The results in exploratory factor analysis showed that seven-factor structure model was appropriate for the scale. Seven factors were outdoor amenity, transportation, leisure activity, social participation, social communication, health and welfare service, social exclusion. The results supported the construct and concurrent validity of the age-friendly scale. Also its good internal consistency was confirmed. The implication and limitation of the study and suggestions for the future studies were discussed.

The purpose of this study was to develop a behavior rating scale for the evaluation of children's development for utilization by preschool teachers. The procedures for the study included content validation, pilot test, and main study. A total of 97 items were retained after the content validation and pilot test. The items of the scale were grouped into five areas (physical, language, cognitive, emotional, and social development) and 11 sub-areas. The resulting "Behavior Rating Scale for Preschool Children" was administered to 479 boys and girls, 3-6 through 6-5 years of age, selected from 10 different kindergartens and early education centers in Seoul, Pusan, and Chonju. The analysis of data was done with SPSS computer programs, including item analysis, Cronbach's ${\alpha}$ for reliability, factor analysis to test construct validity, two-way ANOVA to test age and sex differences, and percentile norms. The 97 items of the scale were found to be satisfactory in terms of item discrimination with indices ranging from .31 to .73. Cronbach's ${\alpha}$ was .98 for the total scale and ranged from .87 to .93 in specific domains, which was considered satisfactory. The factors extracted from each area were consistent with the educational objectives of the Yonsei Open Education Program except for emotional development. The intercorrelations among the domains were relatively high, ranging from .56 to .81. Age differences were significant in cognitive, physical, and language development, but not significant in social and emotional development. Sex differences were significant in all areas with girls higher on the average than the boys. Percentile ranks were drived from the total score for each age group and quartiles were calculated for sub-scores in each domain.

The purpose of this study is to develop the 'Kkondae Scale' and verify its validity. For this purpose, three constructive concepts (attribution error, cognitive rigidity, and one-way communication) were derived through expert interviews, prior research and literature analysis, and 15 preliminary questions were selected. In addition, a preliminary scale was developed by modifying or adding items to conform to each constructive concept through expert content validity evaluation. Next, as a result of the exploratory factor analysis of about 250 adults, a three-factor structure model was derived. As a result of the confirmatory factor analysis on the preliminary scale for about 401 adults, it was confirmed that the fit of the three-factor structure was good. As a result of convergence and discriminatory validity analysis, it was confirmed that the developed scale was a valid tool to measure Kkondae by showing appropriate correlations with listening attitude, empathy, acceptance of others, and intellectual humility. Finally, based on the results of this study, the significance, limitations, and future research direction of the study were discussed.

Purpose: The purpose of this study was to develop and validate a education nurse specialist-led educational satisfaction scale for nurses working at comprehensive nursing care service wards. Methods: A methodological study was conducted. A total of 237 nurses working at comprehensive nursing care service wards in a general hospital participated in this study. The scale was developed through literature reviews, in-depth interview, development of preliminary items, verification of content validity, development of secondary items, evaluation of construct validity, and extraction of final items. Analysis included exploratory factor analysis, pearson's analysis, and reliability analysis using cronbach's α. Results: The education nurse specialist-led educational satisfaction scale for nurses working at comprehensive nursing care service ward consisted of 21 items. Two factors (critical thinking disposition and clinical competency) were identified which explained 63.5% of the total variance. Cronbach's α of each factors were >.95. Conclusion: The results suggested that the education nurse specialist-led educational satisfaction scale for nurses working at comprehensive nursing care service wards demonstrated acceptable validity and reliability. Items of the instrument can assess the level of satisfaction with regards to education led by education nurse specialist among nurses working at comprehensive nursing care service wards.

This study was conducted to validate the Korean Love addiction Questionnaire-Short Form (K-LAQ-SF) applicable to Korean society. As a result of exploratory factor analysis for Love addiction 40 Questions(Peabody, 2005), the final 5 factors and 15 questions appeared, and the model fit of the final scale was confirmed through confirmatory factor analysis. The results of the equivalence test showed that the theoretical structure of the abbreviated scale works in the same way for each gender. The results of correlation analysis between K-LAQ-SF and original scale showed that the abbreviated scale represented the original scale relatively faithfully. Finally, the results of correlation analysis between this scale and relationship addiction, love type and depression showed that convergence, discrimination and criterion validity were secured. K-LAQ-SF is significant in that it can be usefully used to easily measure the characteristics of Korean adults' love addiction in a short time based on stable reliability and validity.

An enhancement in the performance and safety of a high-level waste repository requires a validation of its engineered barrier. An engineering-scale test (named "KENTEX") has been conducted to investigate the thermal-hydro-mechanical behaviors in the engineered barrier of the Korean reference disposal system The validation test started on May 31, 2005 and is still under operation. The experimental data obtained allowed a preliminary and qualitative interpretation of the thermal-hydro-mechanical behaviors in the bentonite blocks. The temperature was higher as it became closer to the heater, while it became lower as it was farther away from the heater. The water content had a higher value in the part close to the hydration surface than that in the heater part. The relative humidity data suggested that a hydration of the bentonite blocks might occur by different drying-wetting processes, depending on their position. The total pressure was continuously increased by the evolution of the saturation front in the bentonite blocks and thereby the swelling pressure. Near the heater region, there was also a significant contribution of the thermal expansion of bentonite and the vapor pressure in the pores of the bentonite blocks.
