컴퓨터의 보급이 보편화 되면서 컴퓨터 보유 가정이 기하급수적으로 증가되고 있다. 이로 인하여 컴퓨터로 할 수 있는 일이 늘어나고, 활용분야 역시 다양해지고 있다. 특히 과거의 교수-학습 방법과는 달리 최근에 많은 분야에서 연구되고 있는 E-러닝, ICT, 컴퓨터 활용, 인터넷 등을 접목하여 학생들의 협동심과 책임감을 요하는 협동학습에 적용하고자 하는 연구가 진행 중이다. 그런데, 협동학습의 집단은 크게 인문계열, 실업계열 고등학생 집단과 중학생 집단으로 분류한다. 따라서 본 논문에서는 컴퓨터를 활용하는 정도와 이용시간 등을 학습에 얼마만큼 도움이 되는지 분석하고, 계열별로 집단을 구분하여 학생들의 집단에서 개인의 적극성과 참여정도에 대한 영향이 집단 전체에 미치는 파급효과를 분석한다. 마지막으로 학업성취에 대한 학생들의 성적차이의 관점을 분석하고, 성별에 따른 학업성취도 차이, 주변 환경에 따른 영향력의 정도, 협동학습의 결과 학업성취도의 변화를 평가한다.

As a result, we could find out that the domestic digital music market is a vertically integrated market centered on ISPs. There were a variety of subjects that led the digital music market from the early digital music in 2000s to the latest streaming market. However, ISP was the only subject that vertically integrated all aspects of content, distribution, and consumption through its subsidiaries and affiliated companies. A variety of combined services, supplementary services, and fare plans provided by using its platform and network have become mainstream services in the domestic digital market and have fixed the current transaction type in domestic market.

The purpose of this study was to investigate high school students' needs for home economics elective courses in line with the introduction of the high school credit system and the development of the next home economics curriculum. To this end, 1,689 high school students across the country were analyzed for needs of home economics elective courses (eighteen elective courses and six sub-disciplines of home economics) and differences in the needs of home economics elective courses based on gender, grade levels, and completion of home economics science subject. The research results were as follows. Among the six sub-disciplines, the preference for 'dietary life' was the highest, and in terms of teaching types, experiment and practice class had significantly higher preference in 'dietary life' than other sub-disciplines. Girls showed higher preferences for home economics elective courses than boys, and the third graders showed significantly higher preferences only for the 'dietary life' sub-discipline than the first graders. High school students who are learning or have learned the home economics science subject showed higher preference for home economics elective courses in all the sub-disciplines than those who have not learned it. Based on the results of this study, it is suggested for the national curriculum development that further researches should be actively carried out to develop home economics career elective subjects.

With the increase in smartphone ownership and Internet usage using smartphones, the information environment is shifting from the existing PC to the smart mobile. The current undergraduate students are called Generation Z who prefer smartphones to PCs and video contents to texts. This study attempted to understand their usage behaviors of electronic resources in an academic library in a smart mobile environment. This study conducted a usage statistics analysis with 61,433 usage records of e-books, audiobooks, and e-learning contents and 1,595 records of users in the A academic library during 3 years from 2016 to 2018. The scope of the data includes the date of use, the subject, the year of publication, the channel of use, and each user's gender, affiliation, status, admission date, and graduation date. This study investigated not only the general characteristics of electronic resource use, but also the usage behaviors according to the user's demographic characteristics. Based on the findings, this study suggested practical service plans that are applicable in the near future and reflect changing circumstances.

본 논문은 5대 재벌 계열사들을 대상으로 재벌의 상호지급보증이 재벌의 지배구조 및 자본구조와 어떤 관련이 있는가를 실증적으로 분석하였다. 지급보증을 분석하면 지배주주의 지분율이 작은 회사일수록 그리고 상장기업일수록 타계열사에 대한 지급보증이 커진다는 것이 확인되었다. 한편 피지급보증을 보면 지배주주 지분율이 별로 영향을 주지 않는 것으로 분석되었다. 이러한 결과는 지배주주와 소액주주사이의 대리인문제가 계열사로부터의 피지급보증보다는 주로 계열사에 대한 지급보증에서 나타나고 있는 것을 시사하고 있다. 부채의존도가 높은 기업일수록 계열사에 대한 지급보증이 크다는 분석결과는 우리나라 금융기관과 재벌사이의 부채의 대리인문제가 심각하다는 것을 시사하고 있다.
