본 연구는 초등학교 4학년과 6학년의 인지발달 차이가 도서관의 이용행태, 독서성향, 도서관 인식에 어떠한 영향을 주는지 고찰하는 것을 목적으로 한다. 이를 위해 서울의 초등학교 세 곳을 선정하여 4학년과 6학년을 대상으로 인지발달 검사와 설문조사를 실시하였다. 그 결과 인지발달이 높은 6학년은 도서관 정보서비스 요구가 4학년보다 많았으나 4학년에 비해 독서량과 도서관 이용이 적고, 흥미 위주의 책을 선호하는 양상을 보여, 인지발달이 높다고 이용행태와 독서성향에 긍정적인 영향을 주는 것은 아닌 것으로 나타났다. 또한 6학년은 도서관 인식에서도 4학년보다 낮았다. 학생들의 도서관에 대한 인식은 이용행태와 독서성향에 의해 영향을 받았다. 즉, 학생의 도서관 이용 정도, 도서 선정 시 사서의 도움 경험, 그리고 교과 연계 도서 선호도는 학생들의 도서관에 대한 인식에 영향을 미치는 것을 확인하였다. 이러한 결과를 바탕으로 5학년 이상의 고학년 초등학생 대상의 발달 단계에 따른 도서관 서비스를 제안하였다.

Background: The purpose of this study is to determine how the cognitive state of the elderly influences the activities of daily living(ADL) in order to increase their achievement capacity and their ability to exercise this capacity in daily life. The MMSE-K(Mini-Mental State Examination-Korean) was used to evaluate the daily activities and cognitive state of a group of subjects more than 65 years of age. The goal was to understand (1) How their achievement level in their daily activities changes according to the increase and decrease of their cognition points by analyzing and comparing their achievement points in the mental state examination, and (2) What variables influence that daily achievement level. Methods: The survey was conducted by a group of students from AnSan College who were trained for this method of data collection. The group surveyed 224 senior citizens older than 65 to determine their ADL performance. The subjects were selected from Silver Care Centers in the Gyounggi Province area including centers in Suwon, Anyang, Kwachun, and Sanbon City. The subjects were given enough information to fully understand the purpose of the study and the method by which it would be conducted. The survey method was a direct interview: which involved an interviewer reading the questionnaire to the subject and recording the answer. Result: The following results were calculated using SPSS WIN ver. 13.0: In the lower score of the MMSE-K regarding ADL performance (K-MBI) for activities such as individual hygiene, bathing activity, food activity, toilet management, going up stairs, getting dressed ad undressed, controlling stools and urination, walking, and chair/bed movement, most of the subjects responded that they could not perform these activities by themselves (p<.01). In the higher scores for the same activities, most response that they could perform the tasks by themselves (p<.01). In the results of the multiple regression analysis, there influence of the variables for ADL performance (K-MBI) and MMSE-K score was higher for females than males. Conclusion: This study evaluated the cognitive state of the elderly using the MMSE-K, which is the most convenient method, and examined how the cognitive state influences the achievement capacity of the daily lives with other variables. In conclusion, the higher the score on the MMSE-K, the more independent the elders are in the activities of daily living, especially among women more than men.

The purpose of this study was to investigate the influence of consumer-internet brand relationship on consumer's satisfaction and loyalty. In order to establish structural equation model, previous studies about consumer-brand relationship, consumer's satisfaction and loyalty were investigated. The survey was limited to the respondents over 20 years old living in Seoul and other metropolitan areas who had purchased fashion products in internet shopping mall. Questionnaires were collected from February 1, 2012 to February 12, 2012 and 562 useful data were analyzed by descriptive statistics, exploratory factor analysis, confirmatory factor analysis, reliability analysis, and Pearson's correlation analysis, using Amos 19. The results of verifying the hypotheses were as follows: First, consumer-internet brand relationship was classified into two dimensions including 'emotional affection' and 'cognitive trust'. Second, both 'emotional affection' and 'cognitive trust' had a positive effect on consumer's satisfaction. Third, 'emotional affection' had a positive effect on consumer's loyalty, but 'cognitive trust' did not affect consumer's loyalty directly. Finally consumer's satisfaction had a significant effect on consumer's loyalty. It was suggested that consumer-internet brand relationship could be an important factor to form brand equity. Therefore, internet shopping mall marketer should establish a strategy that can help customers make a strong relationship with their internet shopping mall.

Multidimensional scaling can be used to identify relationships among concepts, revealing the structure of the cognitive framework by measuring distances within perceptual maps. The current study sought to examine the relationships among concepts related to photosynthesis in 2,844 $3^{rd}-11^{th}$ grade science students. The questionnaire included items on 'location,' 'products,' 'reactants,' and 'environmental factors', presenting images related to each theme. Students provided responses corresponding to particular topics, and reported the extent to which the concept was related to the topic on a scale from 1 to 30. The survey results were as follows: first, students were not able to clearly distinguish between or understand the four main topics. Second, students organized their cognitive structures by closely associating related concepts after learning. Third, the presented concepts revealed a mixture of scientific and non-scientific concepts, suggesting that students needed to clearly distinguish the preconceptions through which they organized concepts, so that they are suitable for cognitive structures based on learning. Furthermore, non-scientific concepts within perceptions were consistently maintained throughout learning, affecting the proximity of scientific concepts.

This study explores the applicability of social capital theory in IT project management. Specifically, an empirical model is developed using different types of leadership competencies (emotional, cognitive, and social) as independent constructs impacting IT project performance. Social capital shared among team members are measured and placed as a mediating construct between leadership competencies and performance. Using PLS analysis of 120 data points collected through a survey of IT project participants in two large electronic manufacturers, direct and indirect impacts of leadership competencies are explicated. Research results reveal that emotional leadership competency seems to directly influence the project performance but not through team social capital, while social leadership competency seems to indirectly influence the project performance through team social capital but not directly onto the project performance. Cognitive leadership competency is the only leadership competency that maintains direct and indirect influence on project performance. Total effect of cognitive competency on project performance is almost two times larger than the total effect of emotional leadership competency and six times larger than the total effect of social leadership competency. Implications of findings are discussed at the end, and further studies are suggested.

Objective: The purpose of this study was to investigate trajectories of child peer interaction and to compare the causal effects of their predictors, including child individual variables (i.e., gender, language ability, and cognitive ability) and teacher variables (i.e., teacher efficacy and teacher-child interaction). Methods: The participants of this study were 263 children and their teachers from the forth to sixth waves of longitudinal data from the Korean Children and Youth Panel Survey by the Korea Institute of Child Care and Education. The data was analyzed using Pearson's correlation and latent growth modeling. Results and Conclusion: The findings of this study are as follows: First, there was a linear decrease in child negative peer interaction over the course of 3 years, and significant individual differences were found in the trajectories (intercept and slope). Second, the predictors had significant casual effects on the trajectories of child negative peer interaction. The trajectories of child negative peer interaction involving girls, higher cognitive ability, and greater teacher-child interaction showed lower degree of intercept and a quicker decrease. Finally, the implications of findings are discussed.
