Purpose: This research was designed to develop an instrument that can be used for measuring of the quality of life for the elderly in Korea. Method: Subjects were 2,110 aged people, residing in Seoul and Kyeungi-Do. In developing this instrument, the researcher first established a conceptual framework based on the literature review and interview and open questionnaire. The collected data were analyzed using the SPSS-WIN program. For the component factors of the measuring instrument, a factor analysis method and item analysis was used. The reliability of the scale was tested by Cronbach's alpha. Result: 1) The results of the analysis of the 32 items making up the instrument were classified into the following 4 factors: life stability, easy of resource utility, health and affection in family, establishment of supportbase. 2) The reliability of the instrument for the quality of life was 0.952 (Cronbach's alpha). In the factor analysis Cronbach's alpha correlations for the 4 factors ranged from 0.736 to 0.949. Conclusion: This scale could be adequately applied in assessing the quality of life for the elderly in Korea. And the results of this scale in a study can contribute to the promotion of quality of life for the elderly.

Purpose: The aim of this study was to develop instrument measuring the relocation stress syndrome for patients transferred from intensive care unit to general ward in Korea. Method: For item construction, components were drawn from an extensive review of the literature, existing instruments and the result of qualitative approach. A total 48 items were selected for the first draft. Ten experts evaluated this instrument for content validity and the number of items was reduced to 29. To refine and test reliability and validity of the instrument, data were collected from the 594 patients following transfer from intensive care unit. Results: Preliminarily twenty-nine items were generated through content validity and a pilot study. Using corrected items to total correlation coefficient, this instrument was further shortened to a 25 item scale. Factor analysis extracted a total of 23 items with a 5-point Likert-type scale. Relocation Stress Syndrome (RSS) included three subscales; physical factors (12 items), Patient's recognition to health care providers (8 items), and emotional factors (3 items). The RSS established content validity, construct validity, and reliability. Conclusion: This instrument demonstrates good reliability and validity, and therefore it is an appropriate measurement of assessing relocation stress syndrome in ICU to ward transition period.

Background: Safety culture, acting as the oil necessary in an efficient safety management system, has its own weaknesses in the current conceptualization and utilization in practice. As a new approach, resilience safety culture (RSC) has been proposed to reduce these weaknesses and improve safety culture; however, it requires a valid and reliable instrument to be measured. This study aimed at evaluating the reliability and validity of such an instrument in measuring the RSC in sociotechnical systems. Methods: The researchers designed an instrument based on resilience engineering principles and safety culture as the first instrument to measure the RSC. The RSC instrument was distributed among 354 staff members from 12 units of an anonymous petrochemical plant through hand delivery. Content validity, confirmatory, and exploratory factor analysis were used to examine the construct validity, and Cronbach alpha and test-retest were employed to examine the reliability of the instrument. Results: The results of the content validity index and content validity ratio were calculated as 0.97 and 0.83, respectively. The explanatory factor analysis showed 14 factors with 68.29% total variance and 0.88 Kaiser-Meyer-Olkin index. The results were also confirmed with confirmatory factor analysis (relative Chi-square = 2453.49, Root Mean Square Error of Approximation = 0.04). The reliability of the RSC instrument, as measured by internal consistency, was found to be satisfactory (Cronbach ${\alpha}=0.94$). The results of test-retest reliability was r = 0.85, p < 0.001. Conclusion: The results of the study suggest that the measure shows acceptable validity and reliability.

The purpose of this study was to develop an instrument for assessing teachers' awareness of science teaching through analogy (ASTA) and to establish its validity and reliability. Based on the literatures on science teaching with analogies, we constructed 23 survey items. Face validity of the items was established using three science education experts. Through exploratory factor analysis with responses of 35 pre- and 26 inservice elementary school teachers, the instruments were constructed on four subcategories: awareness of analogies in science, use of analogy in teaching and learning, self-efficacy in science knowledge, and knowledge of analogy. The data collected from pre- and in-service elementary teachers demonstrated that overall the teachers' awareness of analogy in science was neutral, which indicated they did not have clear standpoints of science teaching through analogy. Further examination demonstrated that there was no significant difference between pre- and in-service teachers and between two genders. Moreover, there was no significant difference among teachers who preferred either didactic or discovery teaching approaches. We conclude that ASTA test would contribute assessment of teachers' awareness of analogy in science teaching while further examination of the instrument will warrant for its broader use.

The study attempted to explore the dimensionality of mother's psychological well-being. The major purpose of the study was aimed at establishing the construct validity regarding the instrument of assessing mother's psychological well-being. Instrument for assessing psychological well-being was developed with 9 variables(sense of control, sense of achievement, sense of confidence, sense of acceptance, sense of intimacy, sense of assistance, sense of immersion, sense of hope, and sense of satisfacion) in 3 dimensions(sense of competency, sense of relation, and sense of improvement) with 4 rating scales of 102 items. After the scale development, the estimates of reliability for the 9-variable scales were Cronbach's ${\alpha}=.71{\sim}.90.$ The correlation between the two scales, Psychological Well-Being Index(Franklin, 1996) and Psychological Well-Being(Ryff & Keyes, 1995) was .21~25. The subjects were divided two groups by the score of the Mother's sense of Psychological Well-Being. And the group has hiher score in Mother's sense of Psychological Well-Being showed the higer score of Perceptions of Parental Role Responsibilities Scale(t=3.24, p=.002).

Purpose: The purpose of this study was to identify the research trends and instruments for assessment of sleep quality in Korea. Methods: 66 quantitative research reports published from 2000 to March 2009 in Korea were selected from 5 databases: RISS4U, KISS, KISTI, DBpia, and the National Assembly Library and were analyzed according to criteria such as publication years, type of journal, participants, study fields, research design, participants, key words and instruments for assessment. Results: Research in sleep quality has been rapidly increasing in recent years. More than half of the research analyzed was conducted in nursing. The majority of research methods were survey and correlational research. Patients with chronic illness and the elderly were the major subjects in those researches. Most research was performed based on hospitals and communities. The types of variables tested for their relation and influence on sleep quality were quite limited. With respect to the instrument used for assessing sleep quality, most studies did not consider whether or not the validity of their instrument had been established. Conclusion: It is recommended to conduct clinically applicable interventional research with an experimental design and to develop a reliability and validity established sleep quality instrument for Koreans.

이 연구의 목적은 중등학교에서의 실험수업을 평가하기 위한 도구를 개발하고 이를 적용하는 것이다. Dana(2001)가 개발한 상황적 실험활동도구를 수정, 보완하여 ‘실험수업의 탐구수준을 평가하기 위한 도구’를 만들었다. 타당도를 확보하기 위하여 전문가들과 여러 차례의 협의를 거쳤으며, 15명의 과학교육 전공 대학원생들에게 의뢰하여 타당도를 검증하였다. 신뢰도를 높이기 위하여 연구자와 평가자 2인이 3개의 전사된 수업을 읽고 난 후, 함께 녹화된 실험 수업을 보여 수준을 달리 하였을 때 도구의 내용을 수정하는 방법으로 신뢰도를 확보하였다. 이렇게 만들어진 평가도구를 4명의 중학교 초임과학교사의 수업에 적용하였다. 그 결과 개발된 평가도구는 중등학교의 실험수업 탐구수준을 결정하는데 좋은 도구라는 것을 확인하였다. 본 연구에 참여한 중학교 초임과학교사의 탐구수준은 확인수준과 구조화된 탐구주준인 것으로 나타났다.
