The purpose of this study was to develop a standardized scale to measure consume's impulse purchasing in internet shopping mall. As internet shopping is expanding rapidly, the consumer's impulse purchasing in the internet shopping is also increased. A preliminary 26-item scale was developed through a literature review. 1230 consumers responded to an online survey using the preliminary scale. This research was made with the intention of not only supplying the academic data on the consumer's impulse purchasing but also understanding the consume's basic behavior patterns in internet shopping mall. Then A series of tests, such as test-retest, item-to-total correlation, Cronbach's reliability coefficient and factor analysis, were conducted using the survey data. The final scale with 20-items was constructed in the end. The consume's impulse purchasing in internet shopping mall Scale for Consumers consisted of 4 factors.

Participants in this study to develop the Korean version of the Early Childhood Home Observation for Measurement of the Environment(EC-HOME) were 294 3- to 6- year-old children enrolled in a child care center and their parents. Results were that EC-HOME had sufficient internal reliability : Cronbach's ${\alpha}=.80$. Correlation of test-retest ranged from .76~.97. In item-analysis, 9 items with low 'corrected item-total correlation' were removed resulting in 30 items. Factor analysis confirmed 6 factors : 1) Learning Material, 2) Learning Stimulation, 3) Responsivity, 4) Physical Environment, 5) Language Stimulation, and 6) Variety of Materials. Analysis of the relation of children's home environment to their characteristic variances with parents and developmental functioning showed high internal consistency and convergent validity of the sub-scales.

The study was performed to compare the raliablity of two Korean version questionaires for respiratory symptoms and ilness being used in Korea. The subjects were 103 dental laboratory technician who divided into two groups as SUN-81-AL and SUN-93. The duration of test-retest was one two month. The differences between two groups interms of average age, height, and weight were negligible. The SUN-93 showed higher agreement compared to SUN-81-AL except items cough and smoking. The Sun-93 deserved to prefer to be used in resporatory epidemiologic study.

The purpose of this study was to develop a standardized scale to measure consumption self-regulation. A preliminary 38-item scale was developed through a literature review. One thousand-twelve consumers responded to an online survey using the preliminary scale. A series of tests, such as test-retest, item-to-total correlation, Cronbach's reliability coefficient and factor analysis, were conducted using the survey data and a final scale comprising 30 items was then constructed. The consumption self-regulation scale consisted of four factors: (1) impulse control, (2) gratification delay, (3)self-reliance, and (4) self-management.

Multi-Layer Ceramic Circuit(MLCC) in the face of thousands of fine pitch multi hole is processed. However, the fine pitch multi hole has a size of only a few micrometers. Therefore, in order to curtail the measurement time and reduce error, the image processing measurement method is required. So, we proposed an image processing measurement algorithm which is required to accurately measure the fine pitch multi hole. The proposed algorithm gets image of the fine pitch multi hole, extracts object from the image by morphological process, and extracts the parameters of its position and feature by edge detecting process. In addition, we have used the sub-pixel algorithm to improve accuracy. As a result, the proposed algorithm shows 97% test-retest measurement reliability within 2 ${\mu}m$. We found that the algorithm was wellsuited for measuring the fine pitch multi hole.

This study examined the developmental aspects of sex role stereotypes among children and the impact of stereotypic and reversed stereotypic sex role content on children's sex-stereotypic thinking. In study I, subjects were 181 Korean children ranging from nursery and kindergarten to grade 1. SERLI was used to measure children's sex role stereotypes. In study II, the subjects were 62 six-year-old kindergarten children of each sex. 4 experimental stories were developed haled on Hong(1991). A test-retest design was used to study sex role stereotypes and the impact of stereotypic and reversed-stereotypic sex role content. Statistical analysis of obtained data was by an ANOVA and two-way analysis of co-variance. Results revealed that 6-year-old children's sex role stereotypes were higher than 5-and 7-year-old children. Boys were higher than girls on children's sex role stereotypes. Children exposed to reversed sex role content changed significantly in the direction of reversed stereotyping.

본 연구 논문은 영 유아를 대상으로 한 사회 정서 문제의 선별 평가서인 Ages and Stages Questionnaire: Social-Emotional (ASQ:SE)의 표준화(신뢰도 및 타당도)연구이다. 특히, ASQ:SE 질문지 가운데에서도 24개월과 36개월용을 이용하여 ASQ:SE 의 내적 일치도 (internal consistency reliability), 재검사 신뢰도 (test-retest reliability), 절선 점수 (cutoff points), 공인 타당도 (concurrent validity)에 대해 연구하였다. 전체 447명의 부모가 참여한 가운데, 237명은 24개월용 질문지를 작성했고, 210명은 36개월용 질문지를 작성했다. 내적 일치도는 24개월 질문지에서 71, 36개월 질문지에서는 .73이었다. 재검사 신뢰도는 24 개월 질문지에서 100%, 36개월 질문지에서 97%이었다. 마지막으로 공인 타당도는 24개월과 36개월 설문지에서 95%이었다. 끝으로, 추후 다양한 대상으로 연구될 것이 추천되며 또한 이 연구에서 제외되어졌던 연령의 ASQ:SE 질문지의 내적 일치도, 신뢰도 및 타당도가 연구되어져야 할 것이다.

Objective : There is an increasing number of people are not satisfied with their appearance and shape. Therefore, assessment tools are needed to evaluate the appearance or body shape. This study investigated the reliability and validity of a Korean version of the Body Shape Questionnaire (BSQ). Methods : Participants completed the BSQ, Body Dysmorphic Disorder Examination-Self Report, Eating Disorder Inventory-2, Beck Depression Inventory, Self-Esteem Scale, State-Trait Anger Expression Inventory, and State-Trait Anxiety Inventory. Results : The Korean version of BSQ presented satisfactory test-retest reliability, internal consistency and validity. Exploratory factor analysis yielded four factors as follow: feeling fat, shame and inferiority about one's body shape, attitudes concerning body image perception, and purging behavior. Conclusion : These results show the Korean BSQ exhibits good psychometric properties and can accurately evaluate the body shape concerns among Korean adults.

This study examined the reliability and validity evidence of the Korean version of Wechsler Primary & Preschool Scale for Intelligence(K-WPPSI-IV), which was standardized recently. Following the stratified sampling for Korean population in terms of region and maternal education level, 1,700 children aged 2.6~7.7 years were recruited for Korean norm development. The split-half reliability (N=1,700) was high(Fisher's z(.75-.89)) and test-retest reliability(N=100) was satisfactory ranging from .95 to .68. The inter-rater reliability(N=110) was very high(.96-1.0). Discriminant and convergent validities were revealed by correlational patterns among subtests and indices. Future studies are needed to extend both reliability and validity of K-WPPSI-IV by collecting data with a various sample group and a variety of instruments.
