The purpose of this study was to develop a scale for evaluation of early childhood programs in Korea. The procedures included content validation and a pilot test. A total of 192 items in 10 major areas was developed based on the review of literature and discussions with professionals in early childhood education. The 10 areas include: scheduling, curriculum, interation, physical environment, materials, nutrition, health and safety, administration, staff qualifications, relationships with parents, and evaluation. The pilot scale was administered to 428 classroom teachers and directors, and 47 college professors in early childhood education. The items were rated on a 3-point scale in terms of importance as evaluation criteria. The methods for data analysis included item means and standard deviations for content validation, Cronbach ${\alpha}$ for reliability, and factor analysis for construct validity. Most items in 10 areas were rated as moderate to highly important (average 2.3), especially items in curriculum and staff qualifications. Two factors emerged from the data: institutional management, and curricular planning and implementation. The Cronbach ${\alpha}$ levels were .70 or higher in most areas, but the range covers from .48 to .91. Based on the pilot data, 143 items were selected for the second year study.

The purpose of this study is to investigate the reliability and validity of the questionnaire of pattern identification (PI) in traditional chinese medicine (TCM), through the systematic review of china national knowledge infrastructure (CNKI) database. We searched the articles related with reliability and validity of the questionnaire of PI and published from January 1994 to December 2013. Seventeen questionnaires were analyzed in this study. The twelve (70.6%) questionnaires were developed on the base of specific disease, and five (29.4%) ones were developed on the base of non-specific disease. Three of PI questionnaires showed low inter-item consistency reliability. Exploratory factor analysis of construct validity, content validity, and criterion validity analysis were commonly used on the assessment of validity, but none of them was analysed at the same study. There was only one questionnaire of the ischemic stroke that examined the sensitivity and specificity of both training and test groups in spite of the absence of a gold standard.

복잡한 시스템에서 취득할 수 있는 여러 가지 형태의 자료에 대한 신뢰도 분석은 각종 시스템에 대한 신뢰도 보증을 위해 필요한 절차이다. 시스템의 신뢰도 평가는 고장함수의 추정에서 시작한다. 시스템은 한 개의 부품만으로 이루어 진 경우도 있지만 여러 개의 부품이 서로 연관관계를 맺고 있는 경우가 대부분이어서 취득된 자료의 형태도 다양하다. 본 논문에서는 고장 사건의 발생확률이 낮은 경우, 서로 다른 두 개 이상의 부품이나 시스템에서 취득한 자료의 형태를 고려하여 이에 대한 고장함수를 추정하고 신뢰도를 계산하는 방법을 제안하였다. 두 개 이상의 부품이 병렬 및 혼합방식으로 연결된 복잡한 시스템에 대한 고장함수의 추정도 자료의 형태를 고려하면 제안된 방법의 확장으로 가능하리라 생각한다.

Purpose: To develop nurses' educational needs scale for woman with infertility. Methods: A total of 201 nurses in charge of infertility health services in 4 infertility hospitals and 1 public health center were enrolled for this study. The scale was developed through literature review, in-depth interview, development of preliminary items, verification of content validity, development of secondary items, verification of construct validity, and extraction of final items. Data were analyzed using item analysis, exploratory factor analysis, Pearson's correlation coefficients, and Cronbach's ${\alpha}$. Results: Nurses' educational needs scale for women with infertility consisted of 41 items. Three factors (education for disease and symptom of infertility, supporting and counselling for infertility patients, and education for daily life of infertile patients) explained 63.7% of the total variance. Conclusions: Nurses' educational needs scale for woman with infertility demonstrated acceptable validity and reliability. Its items could be used to assess the level of educational needs for nurses in charge of infertility health services.

Purpose: The purpose of this study was to investigate level of functioning in patients with stroke using Modified Bathel Index (MBI), World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), and ICF core-set for stroke. Methods: Sixty-four patients with stroke were recruited for this study from nine medical institutes. The ICF core-set for stroke, WHODAS 2.0, and MBI were used to collect subjects' functional levels. ICF core-set was employed here as a standard frame to observe multi-dimension of functioning, that is physiological bodily function, activity and participation (AP) in daily life, and current environmental factors (EF) in patients with stroke. WHODAS 2.0 and MBI were also used in order to have a specific functioning level for subjects. The linkage of each item in WHODAS 2.0 and MBI into the ICF core-set for stroke was examined. Pearson correlation coefficient was used for analysis of their relationships. Results: Functioning level of participants showed moderate resulting from MBI and WHODAS 2.0 ($73.48{\pm}22.27$ and $35.55{\pm}12.53$, respectively). Strong relationship was observed between ICF core-set and WHODAS 2.0, and with MBI. Each item of disability scales was obtained its linkage into ICF in the domain of AP. However, lack of correlation between MBI and ICF in the domain of EF was found due to absence of related factors. Conclusion: MBI was found to be linked mainly into ICF in the domain of AP and to have limited linkage into EF. Therefore, it should be suggested that the ICF concept frame should be used as a multi-dimensional approach to patients with stroke.

Purpose: To develop the stress coping behavior measurement scale(SCBMS) for the workers in manufacturing industry. Methods: Developing of SCBMS was based on job stress and psycho-social health status. Job stress and psycho-social health status were estimated by using the Karasek's job content questionnaire (JCQ) and the general health questionnaire (GHQ-28), and the general characteristics for subjects were estimated by self-reported questionnaire and interview. Result: The subjects were 456 male workers who had never been occupationally exposed to hazardous chemical and other materials, was mean age 31.27 years and mean work duration was 4.81 years. As a result of factor analysis for developed stress coping questionnaire, four factors were extracted such as inactive, active, health and emotional behavior from 15 question items of stress coping questionnaire. Fifteen items passed for item internal consistency (100% success rate) and item discriminant validity (100% success rate). Cronbach's alpha coefficient for each factor ranged from 0.56 to 0.77. The active behavior correlated positively with job demand of JCQ (r=0.12, p<0.05), but total GHQ-28 was negatively correlation (r=-0.24, p<0.01), respectively. Conclusion: These results demonstrated the reliability and validity of SCBMS. Thus, the results may prove to be a useful assessment tool in evaluating stress coping behavior.

Purpose: The purpose of this study was to analysis of effectiveness between cognitive function assessment scores and gaming cognitive rehabilitation system in children with intellectual impairment. Methods: Five children (male=5, $age=10.00{\pm}0.80$) with intellectual impairment participated in this study and were randomly assigned to the experiment that played (received) gaming cognitive rehabilitation system (Neuroworld). The children were applied 2 times a week for 30 minutes during 3 months. The children were assessed K-WSIC-VI (Korean-Wechsler intelligence scale for children-fourth edition) and recorded that gained score in gaming cognitive rehabilitation system before and after intervention. K-WSIC-VI contained five primary index scores: verbal comprehension index, visual spatial index, fluid reasoning index, working memory index, and processing speed index. Gaming cognitive rehabilitation system scoring was composed visual recall, target recall, sequence recall, selective attention, continuous attention, and exploration. Results: In the intelligence quotient (IQ) of K-WSIC-VI, there were significant increased in all children. The visual recall item was highest effective in all children. However, sequential recall showed the lowest improvement in all children. The performance speed of selective attention item was decreased, this means that children's skills have improved. Also, their ability to explore has improved significantly. Conclusion: In conclusion, gaming cognitive rehabilitation system was significant effectiveness in cognitive function in some categories for children with intellectual impairment. However, the visual recall and performance speed don't represent of all cognitive function. Therefore, further studies will need to verify by applying more subject and longer duration.

In order to test scaling assumption, and to assess the validity, reliability, and acceptability of the Short form 36(SF-36) health survey questionnaire, we conducted a survey. Samples were 296 workers who had been employed in small sized companies. All scale passed for item internal consistency(100% sucess rate) and item discriminant validity(100% success .ate). Reliability coefficients were ranged from the lowest 0.51 to the highest of 0.85. For 87.5% of the total workers, inconsistent responses were not observed. Only 3.0% of the total workers failed two or more checks. Factor analysis was performed using principal axis factor method and quartimax rotation. In this survey, the SF-36 retained available psychometric properties even when used in a generally healthy worker group. But further study with some consideration to develope health status measurement is expected : first, the definition of health status should be rationalized. Second, the measurement of outcome is an important consideration in evaluations of quality of care. But ambiguities hinder understanding of this important topic. Third, internal consistency should be interpreted with caution as an indication reliability because it ignores potentially important sources of variation that can occur over time.
