2008년 상반기 국내 민간최종소비지출 중 카드 사용비중은 54%로, 이제 카드는 결제수단의 최대 강자로 자리잡았다. 경제활동인구 1인당 신용카드 소지수도 2002년 4.6매에서 2005년 3.5매로 떨어졌다가 2008년도까지 3.8매 선으로 안정되고 있다. 신용카드 이외의 은행, 증권, 저축은행 등의 현금인출용 카드와 교통카드, 모바일 칩카드, 백화점카드, 학생증카드, 직원ID카드, 마일리지카드, 기타 멤버십카드 등을 합하면 국민들의 지갑은 현금보다도 플라스틱카드로 두툼해져 있다. 이동통신서비스 사업자들은 이동통신단말기를 이용하여 다양한 서비스를 개발 제공함으로써 시장의 주도권을 노리고 있고, 교통카드 사업자들은 자사의 전자화폐인 교통카드로 주도권을 지키려 하고 있으며, 기존의 강자였던 은행과 카드사들은 고객을 빼앗기지 않기 위해 고객이 필요로 하는 다양한 서비스는 제공하면서도 주도권은 지키려고 하는 경쟁과 협력이 활발하게 전개되고 있다. 한편, MS카드는 읽기/쓰기가 쉬워 정보유출, 위변조, 복제 등을 통한 사고의 위험이 커서, 선진국뿐 아니라 중동, 중남미, 아시아 국가들까지도 IC카드로의 전환이 진행되고 있다. 국제브랜드 카드사들은 2006년 1월부터 IC카드가 MS 단말기에서 부정 사용될 경우 그 책임을 매입사에 전가시키는 제도(Transitional Chip Liability Shift Program)를 시행하고 있어 국내 카드사들의 피해도 예상된다. 금융감독 당국은 2003년 2월 “IT및 전자금융 안전성 제고대책”에 의거 2008년 말까지 100% IC카드로 전환을 목표로 연도별 전환목표를 통보하고 지도감독하고 있다. 이에 따라 은행의 현금카드는 2008년 6월까지, 신용카드는 2008년 12월까지 전환을 수행하고 있으나, 기타 금융권이나 카드사용자들은 비용부담, 재고소진 등의 문제로 잘 지켜지지 않고 있다. 특히 가맹점 단말기를 교체하여야 할 VAN사 들은 교체비용이 자기 자본을 상회하는 어려움으로 POS나 CAT단말은 거의 전환이 진행되지 않고 있어 IC카드를 가지고 있어도 MS를 이용하는 형편이다. 카드의 종류는 주도권 경쟁으로 늘어만 가고 있어 애초 취지처럼 하나의 카드로 다양한 사업자의 서비스가 통합되기 어려운데다, 단말기의 표준화도 어려워 막상 카드를 안전하고 편리하게 사용하여야 할 소비자들의 지갑만 무거워지고 있다. 본고는 이렇게 우리의 생활 깊숙이 들어온 카드를 편리하고 안전하게 사용할 수 있도록 하는 인프라는 과연 어느 수준이고 시장의 주자들은 어느 방향으로가고 있는지 살펴보고 그 문제점과 과제를 제시하고자 한다.

Act of journalism is act of social practice. Therefore, judgment on its rightness must be a prerequisite. That is why journalism requires philosophy. Barrenness of journalism philosophy promotes journalism to serve only as an instrument. No power and money should intrude the essential philosophy of journalism. Journalism must secure its own value. Remaining silent when its fundamental value is at risk is to negate one's own value of existence. It is self-denial. Social practice of journalism is assurance and realization of its essential value. Thus, it is historical. It is the juncture of journalism and history. Journalism without history leads to barrenness in philosophy. Without philosophy, journalism thus cannot uphold its historical mission. Journalism philosophy becomes a reality through the history. Concrete journalism philosophy shall come to light through historical reality. That is why conversation between journalism philosophy and journalism history is necessary. Thus, this research investigates how journalism philosophy formulates and reconstructs itself within journalism history. At the same time, this research thoroughly examines how journalism philosophy concretizes in journalism history, how historical subjects have practiced journalism and how all these have projected themselves in journalism history.

This study measures the managerial efficiency of Korea's 14 public enterprises using bootstrap DEA in 2013. In addition, it examines the factors that affect on the bootstrap bias-corrected efficiency using truncated regression analysis. The results and implications of this study are as follows. First, using bootstrap DEA model analysis, the results showed that the mean technical efficiency was 0.3182, the mean pure technical efficiency was 0.4994 and the mean scale efficiency was 0.6585. The main cause of technical inefficiency was due to pure technical inefficiency. Second, rank test between technical efficiency of general DEA model and bootstrap DEA model was no significant difference under CRS and VRS assumption. Third, the main cause of the inefficiency in 11 DMUs among 14 DMUs were mainly due to the pure technology and three DMUs were because of the scale efficiency. Finally, in the truncated regression analysis, cost of labor, profit, sales, return of equity, and the number of employees appeared as factors affecting the scale efficiency at the 10% significance level.

Impact of online social network to cyber community has increased much attention recently. The biggest challenge in fostering a social network is to the extent whether it helps to build human capital network or social community. We propose what critical factors influence the formation of online capital network. The study uses three independent factors as motivation, self disclosure, and interactivity and two dependent factors as knowledge sharing and strengthening relationships to create virtual capital connection. Data collected from 256 university students to test the proposed model. The results of the study shows that all hypothesis are supported except one with strengthening relationship. Implications and limitations of this research are discussed.

Roll의 비판 이후 실행된 많은 국내외 연구결과 CAPM으로 설명이 되지 않는 이례 현상(Anomaly)들이 발견되고 있다. 이례 현상들은 다 요인 모형(multi-factor model)과 같은 추가 위험 요인이론, 표본차이이론, 과잉반응 및 특성이론들로 설명되고 있고 이러한 이례 현상들은 재무관리의 지속적인 관심사인 미래의 주가수익률 예측과 밀접한 관계에 있다. 본 연구에서는 이례 현상들이 주가수익률에 미치는 영향을 알아보기 써하여 Haugen and Baker(1996)의 다 요인 및 수익률 추정 방법론을 국내 증권시장에 적용한 다 요인 모형과 $\beta$, 기업규모, PBR, 과거 1년 주가 수익률에 의한 단일 요인 모형을 이용하여 개별 기업의 포트폴리오 구성기준을 결정하고 이 기준에 의거하여 월별로 편입 주식들을 재조정한 포트폴리오들의 년간 누적 실제수익률 예측력을 비교 분석한 결과 다음과 같은 결과를 얻었다. 첫째, 다 요인모형의 경우 기대수익률이 높은 주식으로 구성된 포트폴리오가 기대수익률이 낮은 주식으로 구성된 포트폴리오보다 실제 년간 수익률이 높게 나타난 반면, $\beta$, 기업규모, PBR, 과거 1년 주가 수익률의 요인에 의한 단일 모형을 적용한 포트폴리오는 이들 순위와 실제 수익률간에는 상관성이 높지 않게 나타나 다요인 모형이 주가 수익률 예측력에 있어서 단일요인 모형보다 우수한 것으로 판단된다. 단일모형 중에서는 PBR을 이용한 포트폴리오가 $\beta$ 단일모형보다 좋은 주가수익률 예측력을 보여 주었다. 둘째, 주가 수익률을 결정하는 유의성있는 요인들은 당기순이익의 증감, 당해연도의 당기순이익의 분포, 자산증가율, 매매 유동성, 매출액 변동, 거래량 추세, 기업크기(시가총액), 과거 1개월간의 주가수익률, 자기자본증가율등으로 나타났다.

The rural elderly population has social capital based on regionalism and kinship, which acts as a positive function in terms of their self-efficacy. Self-efficacy refers to the belief in one's own abilities. In general, elderly people with high self-efficacy maintain a healthy life and age successfully. This study examines how the rural elderly population perceive their self-efficacy and social capital and analyzes the role of social capital as a mediating variable. Social capital consists of 4 aspects; trust, norms, network and participation. For this study, data were gathered from 344 rural elderly people aged 60 years and over. The results of this study were as follows. According to the analysis of the structure equation modeling effect, the direct effect of subjective health status on self-efficacy, the indirect effect of the parameters of norms and the total effect were all statistically significant. Second, the direct effect of adult children's support on self-efficacy was significant, and the indirect effects of the parameters of trust, norms and total effect were all statistically significant. This study confirmed that social capital has a mediating effect on the relationship among the subjective health status of the rural elderly, adult children's support and self-efficacy. Furthermore, social capital had a positive impact on the self-efficacy of the rural elderly. Based on these results, a policy for making use of the social capital of the rural elderly should be developed.

The purpose of this study is to critically interpret generational trends in contemporary Korea through understanding the consumer experiences of luxury bag purchases of women in their late 20s and early 30s. Previous studies on luxury consumption tend to focus on an analysis of the value of luxury products as a sign and a symbol, the characteristics or class identity of luxury consumers, or expressive behavior in terms of ideal self-image. While including these factors, this study also expands the scope to a reflexive understanding of the social structural context behind the phenomenon of personal consumption. This was achieved by considering consumption in terms of the style and practice of everyday life, as well as its opportunities and limitations. In particular, we pay attention to how luxury bags are reproduced as media, which is a process that is circulated back to consumption, and through this process, this study reflects on capitalist life and subjects.
