This study has a purpose of developing a scale to evaluate maternal beliefs on preschool children's education. The subjects were 307 mothers of preschool children in Gwang-ju. The methods for data analyses included a factor analysis for construct validity, Pearson correlations between beliefs and learning-related activities for construct validity, and Cronbach's a for reliability. 4 factors were found, through literature review, in parental beliefs: passive learning, active learning, instruction, and expectation for academic-related skills acquisition. Factor analysis revealed that the 4-factor solution is the best fit. Correlations between beliefs and learning-related activities were statistically significant. Cronbach's a ranged from .65 to .87 for 4 sub-scales. It was concluded that the maternal beliefs scale is acceptable for use.

This article presents the development of a self-report measure of Korean Marital Satisfaction Scale. Based on 'Family Process Model'and interviews with 183 married couple, 3 domain structures with 74 items were identified, which included interactional process, emotional process, and intellectual process. It was administerd to 289 couples to test reliability and validity. Overall reliability coefficients were high for each of the individual domains($\alpha$=.62 to $\alpha$=.93). Face validity, content validity, content validity and concurrent validity respectively were demonstrated good. Additionally, divergent validity with scales of self-esteem and depression was observed. These results support the reliability and psychometric validity of the Korean Marital Satisfaction Scale in the assessment of key dimensions of marital process of Korean couples.

This study presents the rationale for the development of the Comparison Level Scale(CLS) and the Comparison Level for Alternatives Scale(CLAS). Data from 130 married women who live in the U.S.A. suggest that the CLS and the CLAS are internally consistent and unidimensional. The CLS and the CLAS are based on exchange theory perspectives, particularly, Thibaut and Kelley's theory, on evaluating an individual's comparative processes. The scales provide explanatory as well as descriptive power concerning evaluating an intimate relationship.

Prediction of the rotor blade performance is important for determining design factors such as weight and size in development of a small-scale helicopter. Generally, prediction of helicopter performance means the estimation of the power required for a given flight condition. However, due to lack of test data and analyzed results for small-scale rotor blade operated at low Reynolds numbers ($Re{\approx}10^5$), this is not an easy task. As an initial research, this work performs a modeling of a single rotor configuration with FLIGHTLAB and a experimental research with rotor test bed. In this process, we performed small-scale isolated single rotor by experimental and numerical method and achieved good agreement of the hover performance on the test data and simulation results.

Since the concept of software engineering was first used in 1968 by NATO Science Committee, a lot of research work and improvements have been made on software development methodology and software quality control, but they still fall short of ensuring successful development of small and medium scale software systems. Under these circumstances, Center for Software Engineering (CSE) at National IT Industry Promotion Agency(NIPA) has been conducting studies on quality control methodologies of software visualization well-suited for small and medium scale software systems, and also working on the systemization and quantification of software quality control. In this paper, we attempt to scope on the software development management of domestic and foreign small and medium-sized enterprises that are lying in the blind spot, compared to large enterprises with well-organized software development systems. In particular, based on software visualization that CSE is pursuing for small and medium-sized developers, we propose a practical quality control methodology well-suited for small and medium scale projects, and a low-cost quality control management tool by combining open-source quality control tools. Our proposal is expected to induce developers' mind change in SI-specialized small and medium-sized software enterprises, increase their profits and improve customer satisfaction through project quality control.

Objectives : The purpose of this study was to develop the Korean Strength Scale and to examine its validity and reliability. Methods : The Korean Strength Scale is a self-report questionnaire that measures 25 valued strengths and is comprised of 124 items ; each item had a 0-5 rating on a 6-point scale. In order to test validity and reliability, data were collected from 355 adults. The measures included the Korean Strength Scale, HEXACO Personality Inventory (HEXACO-PI), Satisfaction with life scale (SWLS), Positive Affect and Negative Affect Schedule (PANAS), and Orientations to Happiness Questionnaire (OHQ). Results : The resulting exploratory factor analysis of the Korean Strength Scale suggested 4 factor structures. The Korean Strength Scale was shown to have acceptable psychometric properties, including acceptable internal-consistency reliabilities, factorial validity, and high convergent correlations. Conclusion : Although there is room on improvement for some facet scales, the Korean Strength Scale appears to be a useful tool for assessing an individual's signature strengths.

The aim of this study was to develop and validate measures of a mother's reaction to children's negative emotions. After construct factors of a mother's reaction to children's negative emotions based on the theoretical basis and existing scales were explored, the first preliminary items were extracted. After the content validity was confirmed by expert opinions, the second preliminary items were composed, and the initial survey was carried out. Using exploratory factor analysis, three principal factors and 21 items were revealed to be most suitable. The factors of the scale consist of emotion-coaching-reactions, oversensitive reactions, and emotion-minimizing-reactions, respectively. In addition, the reliability analysis and validation analysis of the scale was conducted, by means of surveying 413 elementary students. The internal coherence reliability and test-retest reliability were verified as was the general internal coherence and timing stability of the scale. There were three additional verifications to validate the scale. (1)For the evidence based on internal structure, the confirmatory factor analysis and convergent-discriminant evidence; this resulted in confirming the factor structure of the scale as being reliable. (2)In order to understand the relationships to other variables, the correlation analysis came in effect to the overall scale and each of its sub-factors, showing that they are significantly correlated with the scale of the child's perception on rearing attitudes of the mother. (3)As for evidence based on the consequences of the test, the correlation analysis produced a result showed that sub-factors of the scale have as significant correlation with the child's emotional intelligence and resilience.

In this study, a Korean abbreviation scale to measure love and compassion toward other person was developed based on a critical review on Compassionate Love Scale(CLS; Sprecher, & Fehr, 2005). In the study 1, 12 items were selected from the original version of 21 item CLS by surveying a sample of 207 college students on the basis of several psychometric characteristics (i.e., discriminability, coefficient of factor loading, and contribution to internal consistency). In the study 2, the validity of 12 item version, ACLS (Ajou Compassionate Love Scale), was confirmed by examining the factor structure, reliability, and correlations with other related scales. The results clearly showed that ACLS not only had a sufficient psychometric properties as the CLS, but also superior to the CLS in terms of parsimoniousness. Limitations and implications for future research of ACLS were discussed.

The purpose of this study was to develop an assessment scale for healthy aging of middle aged women. The data were collected from 385 middle aged women in two large cities in Korea. The development processes of the scale were followed: Development of preliminary items; Verification of content validity and reliability; Factor analysis and criterion validity of final items. Results: Factor analysis resulted in the creation of the final scale, which consisted of 38 items that were grouped into 9 factors: self achievement, physical change adaptation, psychological change adaptation, interpersonal relationships, menopausal symptom adaptation, economic stability, physical health, social support, social change adaptation. The explanatory variance was 64.03%. The reliability of the scale was Cronbach's ${\alpha}=.90$. Correlation of the scale with healthy aging and depression, established its construct and concurrent validity was r=-.69, p<.001. The scale was confirmed to have a relatively high validity and reliability. The findings of the study can be useful as a measurement to evaluate healthy aging of middle aged women. Future researches with the scale will be helpful for basic data for the program development to support healthy aging of middle aged women.
