The purpose of this study was to develop a rating scale for measuring children's temperament. The subjects were 622(324 boys and 298 girls) 3-to 7-year-old children. The temperament rating scale was composed of 50 items(4-point Liken scales) was based on mother's interview, RITQ and PTQ. The raters were the subjects' mothers. The data were analysed on dimensions of validity, reliability, and item discrimination. Statistical methods were factor analysis, ${\chi}^2$-test, and calculations of Pearson's r Cramer's V and Cronbach's $\alpha$. On validity 5 factors were extracted, which explained 84% of the total common variance. The 5 factors were named 'malleability', 'activity', 'sensitive reactivity', 'eating habits & physical constraints', 'physiological rhythmicity'. Regarding reliability, Cronbach's $\alpha$ appeared between .66 and .81 among the 5 factors. Regarding item discrimination, the degree of discrimination on all 50 items was significant and acceptable.

The Hwasong City Wall was built for three years(1794-1796), but the real construction term was taken only 28 months. The wall and the buildings on the wall were built simultaneously, and the esttimated construction cost was highly restricted. These conditions were main factors for considering the high efficiency of construction productivity. This study examines these factors that are reflected in the operating system of the architectural standard scale of length, the architectural composition system in the Hwasong City Wall to reduce the construction cost. Through the study, following factors are found. 1.The rule of multiple proportion is found in the relationship between the partition distance, that is, span and the height of the girder which is related to the productivity of ready-made building members. 2.The ruling grade system of scale in the component members is found in the chang-bang(창방, penetration members)

This study developed and validated a 'Parent-child Lexical Interaction Scale for Preschoolers (PLIS-P)'. First, we developed the preliminary scale with 7 factors after reviewing previous literature related to vocabulary and literacy instruction for young children and reflected on feedback from child studies experts and mothers with young children. Subsequently, to validate the scale, the online survey was conducted on mothers with 5-to 6-year-old children who live in Seoul, Gyeonggi, Incheon, Gyeongsang, Chungcheong, Jeolla, Gangwon, and Jeju. Responses from 309 mothers were used to conduct exploratory and confirmatory factor analysis and correlation analysis. The results were as follows. First, the result of exploratory analysis showed that the model with 7 factors was satisfactory: (1) vocabulary exposure, (2) word elaboration, (3) scaffolding, (4) play activity, (5) conventional instruction, (6) word type awareness instruction, (7) word morphology instruction. Second, confirmatory factor analysis confirmed the good fit of the model. Third, the concurrent validity was confirmed by correlation analysis using EC-HOME. Last, the internal consistency reliability of each factor of PLIS-P was also confirmed. This study developed both a theoretical framework of parent-child lexical interaction and a Parent-child Lexical Interaction Scale for Preschoolers. This scale can be used by parents, practitioners, and researchers to acquire knowledge about interaction related to words between Korean parents and young children.

This study sought to develop a 'Meaning of Parenting Scale for Mothers(MPS-M)' in order to measure how Korean mothers perceive the meaning of parenting. To this end, in Study I, a preliminary scale was designed, based firstly on socio-cultural and evolutionary psychological perspectives and secondly on the responses from 118 mothers concerning meaning of parenting. This was followed up by the collection of 887 mothers' responses to the preliminary scale, which then underwent exploratory factor analysis for scale revision. In Study 2, confirmatory factor analysis was conducted on a collection of responses from 548 mothers using the revised scale. Concurrent validity was tested using a parenting stress scale, and reliability was then checked by conducting calculations for internal consistency. As a result, the MPS-M was finally developed, consisting of 25 items under six factors: 'Internal Maturity', 'Restoration of Naturality', 'Familial Union', 'Physical Burden', 'Affective Disorientation', and 'Comprehensive Loss'. Accordingly, the meaning of parenting was statistically confirmed as a hierarchical two-sided concept possessing six factors under positive and negative meaning categories.

Objective: This study aimed to validate a scale which could measure the correct mediation behavior of parents for their children's smart media use. Methods: The subjects were comprised of 514 parents of 5-year-old children. The collected data were analyzed using Jasp. Results: First, in the primary validation process, a total of 19 items and five factors were extracted through exploratory factor analysis. Through secondary validation process, we found that the scale model satisfies the goodness-of-fit evaluation criteria and is valid through confirmatory factor analysis. The newly constructed parents smart media mediation scale in early childhood emerged as a valid and reliable scale. Second, it was found that the more parents pursue 'active mediation', 'instructive mediation', and 'supervision', and avoid 'co-viewing', and 'technical restrictions', the more they had a positive effect on children's smart media usage capabilities. Third, the total score of smart media mediation for young children's parents was found to significantly differentiate young children's smart media overdependence, and self-regulation. Conclusion/Implications: The final smart media mediation scale for young children's parents was composed of 19 items, with five factors: 'co-viewing', 'instructive mediation', 'technical restrictions', 'active mediation', and 'supervision'.

Purpose: Selection-optimization-compensation (SOC) models have been proposed and applied to various populations to examine successful aging from a multidimensional perspective. This study aimed to develop a scale to measure SOC strategy among late middle-aged women (aged 50 to 64 years) and to test its validity and reliability. Methods: Preliminary items were developed through a literature review and interviews. Overall, 32 preliminary items were confirmed via two rounds of expert content validity analysis and a pilot survey. Data were collected from 299 late middle-aged women and analyzed using IBM SPSS/PC+ version 27.0. Construct validity, criterion validity, and reliability tests were conducted. Results: The SOC strategy scale, reflecting the characteristics of late middle-aged women and developed through exploratory factor analysis, comprised 19 items across four factors: goal-oriented selection, compensation for loss, outcome optimization, and ability-based optimization. The scale explained 66.9% of the variance in total factors, with a Cronbach's α of .95. Statistically significant correlations with the reference scale (r=.30, p<.001) were observed. Conclusion: The developed scale demonstrated high validity and reliability, thus representing a viable instrument for measuring SOC strategy among late middle-aged women. Using this scale to assess the use of SOC approaches in these women can improve our understanding of the aging process and help establish supportive programs for their aging journeys.

This study was done to examine the risk factors between controls group and acute brain infarction patients group, and to compare high risk group with low risk group through NIHSS(National Institutes of Health stroke scale). We compared the risk factors between acute brain infarction patients group(N=180) and controls group(N=93). And according to risk factors, we analyzed 1st NIHss, after 3 weeks improved extent within acute brain infarction patients group. The results were as follows. 1. Among the risk factors, HTN, DM, the blood levels of HCY were significantly higher and the blood levels of HDL-C was significantly lower in patients group than controls group. 2. In scale analysis according to risk factors, 1st NIHss were significantly higher in Hypo-HDL-cholesterolemia, Obesity, High-Homocysteine, HTN, DM, previous CVA history group than low risk group within acute brain infarction patients group. 3. In after 3 weeks improved extent analysis according to risk factors, improved extent were lower in Hyperlipidemia, HTN, DM, previous cardiac history, older age group than low risk group within acute brain infarction patients group. The above results suggest that significant risk factors of acute brain infarction, and shows the High risk group that had risk factor of brain infarction recognized from the former research tends to have higher 1st NIHss. Also the High risk group tends to have lower improved extent, but the results are not statistically significant. Furthur research on subject is needed.
