다른 배경음악의 종류와 수준이 어떻게 컴퓨터 문서편집작업의 수행능력에 영향을 주는지를 알아보기위해 18명의 대학생을 대상으로 2인자 혼합인자 실험계획법을 이용하여 실험을 실시하였다. 실험에 사용된 독립변수로는 "클래식, 록, 그리고 한국민속음악"의 3종류를 갖는 음악형태와 "Low (60~65dB), High(80~85dB)"의 2수준을 갖는 음악크기이며, 분석을 위해 수집된 종족변수치는 문서편집작업의 완료시간 및 작업에러수이다. 분산분석을 이용한 통계분석 결과, 높은 (80~85 dB) 배경음악수준하에서는 낮은 (60~65 dB) 수준에 비해 통계적으로 문서편집작업의 완료시간이 많이 걸렸으며, 특히 록음악이 높은 수준으로 연주될때는 낮은 수준에 비해 유의하게 많은 문서편집작업에러가 발생하였다. 많은 문서편집작업에러가 발생하였다.

This paper examines the effects of corporate governance on internationalization in Korean firms. Using the data from 454 Korean manufacturing firms listed in the Korean Stock ExchanFge (KSE) from 1999-2006, we analyzed the role of corporate governance on internationalization in Korean firms, including Chaebols (Korean business groups) and family firms. In addition, we investigated the moderating effect of concentration of ownership on internationalization. The results of the analysis showed a positive association between corporate governance in Chaebols and family firms and internationalization. Interestingly, the influence of ownership concentration overpowered the ambivalent behaviors of Chaebols, leading to less internationalization. We conclude that corporate governance in Chaebols and family firms is important to internationalization strategy.

This study analyzed the impact of ICT usage on elementary and secondary school students on the result of ICT literacy levels for finding out why most of students were 'normal' or 'basic'. As a result, we found out that the learning action, information searching and leisure action of student using ICT had correlation with ICT literacy level. The higher the rate using ICT for learning, information searching and leisure, the higher the ICT literacy level of student. But the higher the rate using ICT for communication, the lower the ICT literacy level of student. Accordingly, we proposed the policy not to increase simply ICT using of student, but to teach how to use ICT for learning and information searching.

This study examined the longitudinal relationship between paternal depressive symptoms and maternal depressive symptoms simultaneously. This study also identified the interplay of paternal and maternal depressive symptoms for predicting elementary children's language development, their problem behaviors and their school adjustment. Using the data from the Panel Study on Korean Children for the 4th-8th years (2011~2015 year), this study used the Latent Growth Curve Model, which is helpful for examining longitudinal relationship differences among variables. The sample subjects were 1,754 parents and children. The results are as follows. The initial level of paternal depressive symptoms had a positive impact on the rate of change in maternal depressive symptoms. The initial level of maternal depressive symptoms had a negative impact on the rate of change in maternal depressive symptoms. Mothers' depressive symptoms showed not only the mothers' own depression problem. but also the self-effect and counterpart effect of depression on the fathers' depression problem. The rate of change in maternal depressive symptom mediated the relation between the initial level of parental depressive symptoms and children's receptive language, internalizing/externalizing problems, and school adjustment. Therefore, depression prevention and intervention programs for both fathers and mothers are needed for the healthy development and school adaptation of school-age children.

The purpose of this research is to find the effects of learner-centered instruction based on constructivism (LCIC) on their knowledge generation level and reasoning ability. To look for them, after fraction units are re-planed for implementing LCIC, instructions using it provide students in a class. From the data, some conclusions can be drawn as follows: LCIC has more positive influence of students on recall ability, generation ability, and reasoning ability than tractional instruction method. With the data it can be said that the interaction exists between learners' reasoning ability and generation level.
