  • This study analyzed the effects of dynamic assessment in terms of scaffolding group types and young children's measurement ability levels. Participants were five-year-old children in Busan divided into 2 experimental groups and control groups. The Assessment Tools for Young Children's Measurement Ability (Ko & Hwang, 2008) consisted of 4 sub tests for ‘length', 'width', and 'weight' concepts. Data were analyzed by t-test and ANOVA. Results showed significant differences between experimental and control groups in post-test scores, but no significant differences between individual and peer collaboration groups in amount of scaffolding. Significant improvements showed in all of the measurement ability level groups : individual higher, individual lower, peer collaboration higher and peer collaboration lower level scaffolding groups.

  • The differences of coping behaviors of professional and non-professional working mothers were assessed using data(n=704) from the working mothers with children under age 18. Professional working mothers' individual characters family and occupational conditions are more suitable than non-professionals for the coping behaviors. And such individual and situational aspects may relate to the differences of coping behaviors of he two groups. In general professional working mothers use coping behaviors more except the 'role reducation' and 'taking the support of fiends & neighbor' On the other hand the conservativeness and passive attitude in role strain coping is the same aspect of the two groups. Finally the relation of individual character family and occupational condition of working mothers to their coping behavios are slightly different in this two working mothers groups.

  • 작업기억의 읽기 범위에 따른 개인차가 무관련 정보의 억제과정에 작용하는 과정을 살펴보기 위해서 두 개의 독립적인 실험을 실시하였다. 실험 1은 탐사재인과제을 사용하였으며 작업기억 범위가 작은 폭 집단에 비해 큰 폭 집단에서 관련정보의 촉진적 활성화 기제보다는 무관련 정보의 선택적 억제기제가 잘 작동한다는 결과를 얻었다. 실험 2의 어휘판단과제에서도 동일한 결과를 보였으며 두 실험 모두 큰 폭 집단이 작은 폭 집단에 비해 기억부담의 영향을 받지 않는다는 공통된 결과를 얻었다. 이러한 결과는 억제가 작업기억 개인차를 설명하는 중요한 요인임을 시사해준다.

  • This study attempted to examine a speaker identification method using difference sum and correlation coefficient determined from a pair of intensity level matrices of band-pass-filtered numeric sounds produced by ten female speakers of similar age and height. Subjects recorded three digit numbers at a quiet room at a sampling rate of 22 kHz on a personal computer. Collected data were band-pass-filtered at five different band ranges. Then, matrices of five intensity levels at 100 proportional time points were obtained. Pearson correlation coefficients and the sum of absolute intensity differences between a pair of given matrices were determined within and across the speakers. Results showed that very high correlation coefficient and small difference sum generally occurred within each speaker but some individual variation was also observed. Thus, the matrix pair with a higher coefficient and a smaller difference sum was averaged to form each individual's model. Comparison among the speakers yielded generally low coefficients and large differences, which suggests successful speaker identification, but among them there were a few cases with very high coefficients and small differences. Future studies will focus on finer band ranges and additional spectral parameters at some peak points of the intensity contour at a low frequency band.

  • In this study, the various financial management systems practiced by modem dual-income families were assessed by in-depth interviews with 6 people, 3 practicing integrated financial management and 3 practicing individual financial management. The results indicated significant differences between the two financial management methods regarding family structure, individual values, and family finances. Families that practiced individual financial management consisted of weekend couples without children who showed an individual-centered value tendency and seemed to take a positive attitude towards their future economic situation due to possession of their on stabilized financial assets. Based on these results, we can expect more families to adopt methods of individual financial management and show a wider variety in their financial planning tools which will require adequate and efficient countermeasures and strategies suitable for each financial management practice.

  • The purpose of this study was to investigate social support buffering stress symptoms and the relationship between stress symptoms and job performance. The data were obtained from questionnaires completed by 529 workers employed in textile or clothing companies. The SPSS package was used for data analysis which included t-test, ANOVA, and correlation analysis. The results showed there were significant differences in the perceived levels of social support according to individual differences such as gender, marital status, length of service, title of current position, and division of responsibility. Workers with a high level of supervisor or co-worker social support were found to have the lower levels of stress symptoms. Social support appeared to moderate the relationship between stress symptoms and job performance.

  • Several contributing factors have been proposed for expression of excessive anxiety. Behavioral inhibition, activation of amygdala, and genetic vulnerability interchangeably affect each other. Only few studies have addressed the differences and similarities in anxiety between animal and human. The consensus is that individual vulnerability is a main factor for the expression of anxiety, although the interaction of environmental stressors and biological characteristics is involved in the presentation of anxiety. Further work is required to investigate how the interaction between stress and diathesis can affect responsiveness of stress and anxiety in animal and human. Here, the author reviews the findings regarding differences and similarities in both animal and human studies. Knowing the reciprocal relationship between the environment (stressors) and individual vulnerability or resilience, the proper understanding of anxiety and anxiety disorders would be possible.

  • A roentgenographic cephalometric study was made on the soft and hard tissue profile of Korean adults. The subject consisted of 52 males and 54 females from 17 to 22 years of age and with normal occlusion and acceptable profile. Twenty one landmarks were plotted and two oriented lines named SnH line and SnV line were drawn on the tracings of all cephalograms. The means and the standard deviations from the subjects were calculated in each measuring category and the means were compared with those of male and femal samples. The results were obtained as follow: 1. In depth and height, individual variations and sex differences of the lower facial profile were larger than the upper face. 2. The sex differences of upper facial profile were larger in height than depth. 3. The individual variations and sex differences of the top of nose were the smallest in all measuring points. 4. The thickness of the soft tissue of upper face and upper lip in male sample were larger than those of female, but the same matter were not found in mental region.

  • This article reports the developmental stability of individual differences in children's attachment qualities with their mothers and the relations between the preschoolers' attachment security to mothers and maternal parenting behavior. 24 infants were observed with mothers in the Strange Situation to assess the infant-mother attachment patterns at 16 months of age. After 3 years, attachment security was assessed using Attachment Q-Set, and the modified IPBI (Iowa Parent Behavior Inventory: Mother Form) was administered to mothers to assess their parenting behavior. Analyses revealed significant differences in children's attachment security scores by infancy attachment patterns. That is 11 of 12 children's attachment to mothers qualities were stable across the 3 year periods. The attachment security scores related positively to the responsive maternal parenting behavior. Changes in child-mother attachment quality over time were related to maternal responsiveness. Collectively, these findings were consistent with predictions from attachment theory.
