  • 본 연구에서는 우리나라 266개 상장기업을 대상으로 기업다각화의 동기를 밝히고, 대리권문제와 기업다각화가 기업가치에 미치는 영향을 분석하였다. 기업다각화수준의 결정에 있어 대리권문제의 영향을 분석한 실증결과에 의하면, 첫째, 내부 지분율이 낮을수록 다각화가 많이 이루어지고, 내부지분율이 높을수록 다각화수준이 낮아지는 것으로 나타나, 우리나라 기업의 다각화 동기를 대리권문제 관점에서 찾을 수 있음을 알 수 있었다. 둘째, 외부대주주지분율과 다각화수준간에는 유의적인 관계를 발견하지 못하여, 외부대주주들이 경영자를 감시 통제함으로써 대리권문제를 축소시키고, 기업의 다각화를 억제할 것이라는 가설은 기각되는 것으로 나타났다. 다각화가 기업가치에 미치는 영향에 대한 분석결과에서는, 첫째, 다각화가 기업가치의 감소를 유발시켜 다각화수준이 높을수록 기업가치가 낮을 것이라는 가설은 기각되는 것으로 나타났다. 오히려 우리나라 기업에 없어 다각화는 기업가치에 긍정적인 영향을 미치는 것으로 분석되었다. 둘째, 관련다각화 기업과 비관련다각화 기업의 가치를 비교해본 결과 비관련다각화 기업의 가치가 관련다각화 기업의 가치보다 높은 것으로 나타났다.

  • 배경: 이상적인 판막의 개발이 있기 전에는 가능하다면 원래의 판막을 보수하는 것이 좋을 것이라는 생각이 당연하며 실제 임상연구가들은 기술적으로 가능하다면 판막재건술이 판막치환에 비해 대단히 좋은 임상경과를 취한다고 보고하고 있다. 그러나 판막 치환례에서 수술성적과 임상성적이 오히려 좋게 나타나는 경우 이유가 있을 것이고 그 근본원인은 심실의 기능에 따라 좌우되리라는 가설 하에 이를 규명하고자 하였다. 대상 및 방법: 순수승모판막폐쇄부전증으로 수술 받은 40명의 환자를 대상으로 하여 고전적 판막 치환술을 시행한 12례를 1군으로, 후엽을 보전한 18례를 2군으로 그리고 성형수술을 시행한 10례를 3군으로 나누어 수술전의 심에코 소견을 포함하여 입원시에 시행한 전신상태와 수술 후 4주 이내에 시행한 심에코도의 각종 지표를 시행하였다. 결과: 일반적인 환자의 상태변화로는 1군에 비해 2군, 3군에서는 더 나은 결과를 보였으나, 통계적인 차이는 발견할 수 없었다. 뉴욕 심장협회의 분류에 따라서는 수술전보다 많은 호전이 보였으나 세군간의 유의한 차이는 발견할 수 없었다. 심에코도에 따른 심기능을 비교한 바에 의하면 1군에서는 오히려 나빠졌으며 2군, 3군에서는 수술직후에는 술전에 비해 별 차이가 없으며 회복후에는 모든 지표에서 의미있는 호전을 발견할 수 있었으나, 구별분획에 있어 두 군간에는 수술전, 수술후, 회복후의 상호간의 통계적으로 의미 있는 차이는 발견되지 않았다. 결론: 심기능의 차이가 나므로 승모판막폐쇄부전증에 대한 수술로는 가능한한 판막 성형술이 좋고, 판막 성형술이 불가능한 변형이 많은 경우 판엽 일부를 보전이라도 하는 것이 좋다.

  • There has been discussions and investigation on the nexus between religion and citizen's supports for suicide attacks and terrorist groups conducting such acts. In terms of the relationship, there were two potent hypotheses attempting to explain the process and mechanism of the relationship: religious belief hypothesis and coalitional commitment hypothesis. previous studies examined these hypotheses have been carried out across different cultural, religious, and political contexts. Until today, however, there are still lack of concrete evidence, which is generated from empirical studies, supportive evidence for any of these hypotheses. Therefor this study aims to investigate the association between religion and popular support for suicide attacks by using a survey data collected from three middle east countries, Egypt, Morocco, and Pakistan. In analysis, a step-wised regression analysis conducted with a set of variety of variables considered to be related with the association. This study found that variables reflecting religious belief hypothesis, such as prayer to God, religious devotion were unrelated to support for suicide attacks. Yet, prayer time predicted reduced supports for suicide attacks. Further, attendance at religious services, thought to enhance coalitional commitment, predicted support for suicide attacks. Yet, it showed negative association with support for suicide attacks. These findings suggest that regular attendance at religious services and regular prayer have combined effects reducing on the willing to support for suicide martyrdom. However, this study findings affirmatively support for neigher religious belief hypothesis nor coalitional commitment hypothesis. Instead, it suggests the needs for further research examination on the relationship as well as corrections of these hypotheses. Finally, Implications for the research findings for preventing suicide attacks are discussed.

  • The study analyzes the trend of regional economic development disparity in China, sets up research period from 1952 to 2008, and uses the after-modified regional GDP data by the first national economic census in 2004. The results as follow. Firstly, the Coefficient of variation(CV) with after-modified GDP data lower than the pre-modified data. Secondly, generally speaking, after-reform and open period's disparity lower than pre-reform and open period. In particular, the regional development disparity increased slowly after 1990, not rapidly. Third, the new cycle of the inverse-U type is appeared from 2002. Fourth, compared with Herfindhal-Hirschman index(HHI) and Theil Entrophy index(TEI), the lower level regions more affect to reduce the disparity in 1980s, and it also affect to reduce the disparity after 2000. Fifth, the convergence hypothesis test finds that the regional economic development disparity has been converged in 1978-2008. Sixth, the inverse-U type hypothesis not has statistical significance, from 1952 to 2008, but it has statistical significance from 1991 to 2008. This result same as the CV and the convergence test.

  • The purpose of this study is to investigate the effect of technology acceptance model (TAM) on behavioral intention in order to grasp the degree of technology acceptance on autonomous driving among the various factors that consumers perceive as unmanned vehicle system becomes commercialized. In addition to the mediating effect of perceived usefulness proposed by the existing TAM, this study proposed the perceived trust (PT) and hypothesized its mediating effect on behavioral intention to use the self-driving. Path anlaysis is adopted to investigate our hypothesis using the structural equation model. The sample used for the analysis was 149 valid data among 160 responses. The effects of total effect, direct effect, and indirect effect were confirmed by hypothesis test on mediating effect. Non-parametric bootstrapping analysis was also performed to confirm the robustness. All the hypotheses were significant and we found a partial indirect effect, which implies that mediation effect of PT on behavioral intention.

  • The purpose of this study was to examine the effect of twitter influenctials on users' willingness on express opinions. Based on the spiral of silence and corrective action hypothesis, the contradictory hypotheses were drawn. The online expeiment was conducted to verify which hypothesis is valid. Participant were assigned to the four experimenatal conditons: a famous influential's twit which agrees with the issue; a famous influential's twit which disagrees with the issue; an ordinary influential's twit to agree with the issue; an ordinary influential's twit to disagree with the issue. Results showed that opinion congruency with a twitter influential did not influence participants' willingness to express opinion online and offline, but the interaction effect with the type of influentials was found. Opinion dissonance with an ordinary tiwtterian increased willingness to express opinion. The findings suggest that twitter influentials, particulary an ordinary influentials with differnet opinions, can motivate users to express their own opinion.
