  • The purpose of this study is to develop a textile knowledge checklist and to analyze university students' textile recognition. After analyzing reliability, difficulty, and discrimination of questions, we developed a standardized tool to measure textile knowledge. The tool has 72 checklist questions, which can be divided into 4 parts: basic property, comfort, management, and finishing. The level of university students' textile knowledge was 68.91 %. The level of basic property was 75.56%, comfort 70.83%, management 64.5% and finishing 64.74%. The recognition of management and finishing was lower than that of basic property and comfort. There existed a significant difference in the textile knowledge by their gender, major, and school year. To elaborate, females, clothing and textile major students, and juniors and seniors showed higher level of textile knowledge. It seemed that comfort was more professional item than management in textile knowledge.

  • The purpose of this study is to conceptualize the definition of school readiness specific to the context of the Republic of Korea. The school readiness test can be used as basic data to enable early childhood educational institutes to determine the general readiness of preschoolers and provide support to fit individual characteristics. For this purpose, six stages of the school readiness development process were considered, that is, draft development, primary preliminary survey, primary expert verification, secondary expert verification, secondary preliminary survey, and main survey. In the main survey, tests were conducted using the school readiness final draft targeting 344 preschoolers living in Seoul and Gyeonggi-do. The item discrimination power analysis and factor analysis for the examination area and question area were also conducted. Consequently, a test tool was developed on the basic of the results obtained, consisting of 129 items in the five areas of knowledge, function, adaptation, tendency, and attitude. The knowledge area was divided into general, linguistic, and mathematical knowledge, and the function area into fine motor function, basic living ability, expressive function, and gross motor function. The adaptation area was classified into adaptation activity, separation anxiety, maladaptive behavior, and environment adaptation; the tendency area into learning tendency; others understanding, and individual tendency, and the attitude area into rule compliance and life habits.

  • It is important to examine patients' subjective evaluation as well as objective measures and clinician's rating to assess voice disorders. This study aimed to evaluate validity and reliability of Korean-version of Voice Handicap Index (KVHI) and Voice-Related Quality of Life (KVQOL) with 113 adults with voice disorders and 111 normal adults. Content validity was verified by three experienced speech-language pathologists. Concurrent validity was revealed by examining the correlation among KVHI, KVQOL, and Voice Rating Scale as well as item discrimination coefficients. Total scores of KVHI and KVQOL of adults with voice disorders were significantly different from those of normal adults. Test-retest reliability and internal consistencies were significantly high in both KVHI and KVQOL. Correlations among scores of each subscale and total score were also significantly high in each tool. The study revealed that KVHI and KVQOL are suitable tools to be used in clinics and research areas in Korea, which can subjectively evaluate the effects of voice disorders on daily life as well as on quality of life.

  • Recently, as the characteristics and production methods of the construction industry are changing, and women are actively entering the society, the view of women in the construction industry is also gradually changing. Although the government is currently improving the system to expand women's participation, nevertheless, women's participation in the construction industry is very low compared to other industries. The scope of this study was limited to presenting the actual working environment and improvement plans for male and female engineers in the design office. As a result of the survey on the insufficient part of the work environment, the item 'rest space such as lounge, bathroom, and conference room was narrow' was highly surveyed for men, and 'there was no rest space that required gender discrimination' was highly surveyed for women. As for the improvement measures, both men and women were surveyed highly in the category of 'My place for personal work'. In this study, the scope of the study has a limitation in that it only presents the actual situation and improvement measures for the working environment for male and female engineers in the design office.

  • The present study aimed to develop an instrument to assess young children's understanding of science inquiry skills. For the purposes of the study, based on analysis of literature and evaluation tools related to young children's science inquiry skills, five categories of understanding science inquiry skills including observing, classifying, predicting, measuring, and discussing were selected. Then 30 test items were developed and verified three times through opinions from science education and early childhood education professionals and teachers. Finally, a total of 19 test items within five categories were developed. The 19 items' item difficulty, item discrimination, and item internal consistency were verified statistically. In addition, concurrent validity and test-retest reliability of the items were verified by the significant correlation coefficients. The instrument developed in this study was administered to 300 children who were 3, 4, and 5 years old. The results showed that 5 year old children had better competence to understand science inquiry skills than 4 and 3 year old children, while there were no differences in the competence between boys and girls.

  • The purpose of this study is to emphasize the importance of the safety and health ability to safely protect body in a risky situation in infancy, but due to the lack of a valid test tool for measuring infant safety knowledge, measure the safety and health knowledge of infants. In order to achieve the purpose of the study, opinions of education experts and early childhood education experts were collected, and suitable factors for measuring safety and health knowledge of children aged 3-5 years were extracted. The measurement questions developed based on this were surveyed on 186 children aged 3-5 years old to verify the relevance of the question composition and the reliability of the contents. In the distribution of the item response, values of 0.8 or less were deleted, and items with a correlation of r<.40 or less were also deleted, and the reliability test showed more than .70. After exploratory factor analysis, it was developed into 23 questions in 3 areas. The total score of safety and health knowledge for the final question and the degree of correlation were above .80. The tool for measuring child safety and health knowledge developed in this study was confirmed to be appropriate for item discrimination, item reliability, and content validity, and thus will be used as basic data for measuring child safety and health knowledge. After the early childhood safety and health education program is implemented, Further research should verify the effectiveness of the early childhood safety and health program.

  • The present study is designed to investigate the effect of perceptive, emotional and semantic distinctiveness on retrieval-induced forgetting(RIF). Experiment 1 was designed to construct a category and category list for RIF experimental paradigm and to investigate the effects of perceptual distinctness on retrieval-induced forgetting. It was used for the list consisting of the six categories and six words in each category list. In controlled conditions, all the stimuli were presented in black and Gothic. In contrast, perceptual distinctiveness conditions, half of the category list were presented in red and Gungseoche. RIF was observed in all conditions. Experiment 2 was designed to investigate the effects of semantic and emotional distinctiveness on retrieval-induced forgetting. In neutral conditions, adjectives related to items were added. In the emotional distinctiveness condition, half of the items in the category were manipulated in such a way as to add the negative adjectives. In the semantic distinctiveness condition, half of the items in the category were manipulated in such a way as to add the inappropriate adjective. As a result, RIF occurred in the neutral condition, but RIF did not occur in both the emotional discrimination condition and the semantic discrimination. These results suggest the possibility that the RIF will not occur when the distinctiveness occurs within a categorical relationship.

  • Objective : This study aimed to establish an analytic methodology that can objectively evaluate the proverb comprehension levels that vary based on the aging process. Method : This study recruited 70 normal elderly aged ≥ 65 years and performed proverb comprehension tasks using an explanation method. A scoring estimation method was designed on 3 and 5-point scales. The difficulty and discrimination levels were calculated based on the two scales, thereby selecting the final questions and evaluation scale. Results : First, the item discrimination index on the 5-point scale was relatively higher than that on the 3-point scale, and 10 items were finally selected. Second, in terms of proverb comprehension ability, the elderly group aged 70 ~ 84 years showed significantly lower performance than those aged 65 ~ 69 years. Additionally, subjects with ≥ 10 years of education showed significantly higher performance than those with 9 ≤ years of education. Third, the performance of the proverbs comprehension task negatively correlated with the reaction time of the executive function task. Conclusion : Proverb comprehension is a task that can distinctively show a deterioration of brain functions in line with the aging process even among the normal elderly group and therefore, can estimate the difference more effectively with an increase in the score of the evaluation scale.

  • This study evaluated the effect of diabetic group teaching programs in one university hospital in Seoul to predict when re-education would be needed. This study examined the patients’ knowledge at four points (before, directly after, three months and six months after the teaching program) and self-care performance related to diabetes twice (three months and six months after the teaching program). The subjects of the study were 24 admitted diabetic patients who participated in four-day teaching programs. Data were gathered from January to October, 1992 by means of an instrument developed from two diabetic knowledge tests which were equivalent in item differentiation and item discrimination coefficients. Collected data were analyzed by paired t-test, Pearson correlation, t and F tests. The results of study were as follows. 1. The analysis of the effect of the diabetic group teaching program and the duration of the effect of teaching. 1) The first hypothesis, that the diabetes knowledge score directly after the teaching program would be higher than before, was rejected (t=-1.40 ; p=.172). 2) The second hypothesis, that the diabetes knowledge score directly after teaching would be higher than three months later, was rejected(t= -4.27 ; p=.000). 3) The third hypothesis, that the diabetes knowledge score three months after teaching would be higher than six months later, was supported(t=2.43 : p=.020). 2. The relation of knowledge and self-care performance 1) The forth hypothesis, that the level of self-care performance related to diabetes three months later would be higher than six months later, was rejected( t=1.49 ; p=.146). 2) The fifth hypothesis, that the higher the diabetes knowledge, the higher the level of self-care performance, was rejected(r=.2086 ; p=.118). 3. The relation of diabetes knowledge and self-care performance according to demographic variables and structural variables of diabetes. 1) Diabetic knowledge scores varied according to the educational levels of the clients directly after the teaching. Three months after the teaching program higher educational levels and higher economic status were related to higher diabetic knowledge scores and men had higher knowledge scores than women. 2) Self-care performance scores of men were higher than those of women at three months and six months after the teaching program. 3) Before the diabetes teaching, the diabetic knowledge scores of subjects who had a diabetic patient in the family were higher than those who did not have patient in their family. Six months after the teaching, the diabetic knowledge scores of subjects who read the distributed books about diabetes were higher than those who did not read them. 4) No significance differences were found be-ween self-care performance and structural variables of dialetes. The results of this study indicated that the levels of diabetes knowledge and self-care performance incense of three months after the teaching program but decrease of six months. Reeducation would be needed between three and sir months. The investigator thinks that a study of the content and teaching methodology is needed to increase the education effect. The subjects want to hear patient histories of diabetic management. Group discussion would be helped after the teaching sessions.

  • There is recent recognition that the approach toward family members is crucial for understanding problems in multi-cultural families by emerging from typical approach focused on migrant women. While researches have reported serious conflicts and adaptation problems from cultural difference between parent-in-law and foreign daughter-in-law, cultural stress of parent-in-law has not been systematically examined. The purpose of this study was to develop and validate a scale to measure acculturation stress of parent-in-law who have a foreign daughter-in-law. The sample consisted of 266 parents-in-law from three provinces of South Korea. Initially, 16 items were generated based on the existing scale of acculturation stress and they are tested by item-analysis through the descriptive and correlational analysis. An exploratory factor analysis was conducted to investigate the factor structure of the scale and a confirmatory factor analysis was used to validate the scale. By item-analysis, five items were deleted from initial scale items because of redundancy. Findings from an exploratory factor analysis provided the evidence that the scale consists of three factors which are the perception of prejudice and discrimination, conflicts from different cultural value, and daily discomfort. Cronbach's ${\alpha}$ for the scale is 0.86. Multiple fit indices from confirmatory factor analysis indicated that the hypothesized three-factor model for acculturation stress achieved a good fit with the data. Results showed the evidence for the reliability and validity of the scale for acculturation stress of the parent-in-law who have foreign daughter-in-law. The scale would have potential effects for assessing psychological stress for parent-in-law in research and clinical practice. Further implications and limitation of the study and suggestions for future studies were discussed.
