In the existing researches about the Internet and mobile phone addition for primary and secondary school students, the major addiction testing measurements are personal parameters such as obsession, self-efficacy, and self-control and environmental parameters such as parents, friends, schools, community factors, and mass media. Those researches have focused on the interaction objects between a student and him/herself, parents, friends, schools, or society. While the importance of time perspective has increased recently, there have rarely been the research that had focused on it in education arena. In this paper, we analyze how time perspective influences the Internet and mobile phone addiction levels of primary and middle school students. In order to do that, we surveyed 619 primary and middle school students and analyzed the results in this paper. And then, we renew the relative importance among existing factors for the two addictions and propose the way to prevent the two addictions.

Intangibility, measurement difficulty and irreversibility, which are the characteristics of service, have such problems as obscurity and uncertainty in quality evaluation. Technical entrepreneurship education, a sort of public service, also contains such characteristics of service. To objectively evaluate the service quality of technical entrepreneurship education, this paper drew up factors as hierarchical structure, centered on FAHP technique, and conducted pre-processing, inputted those factors into triangular fuzzy number fuzzy judgement matrix, and calculated their weights. In this manner, this paper proposed a TESE system, through which an analysis can be conducted by drawing relative importance and priorities of the factors. The proposed system can efficiently evaluate the qualitative technical start-up education service quality factors quantitatively in the diversely changing technical start-up environment in view of the highest result quality (41%), which means performance in the relative importance of major factors. Namely, this paper confirmed that clear decision making can be made through an experiment.

This study analyzed the relationship between elderly suicide rates and socio-economic factors from the macroscopic perspectives. As certain theoretical background of elderly suicide, sociological and economic perspectives are applied. The economic factors of elderly suicide rates consisted of economic growth and unemployment rate, economic activity rate of the aged, and relative poverty rate (income inequality rate). The sociological factors included social welfare spending, divorce rate, growth rate of population aging, and elderly dependency ratio. According to research findings, first, the more economic activity of the aged is low, the more elderly suicide rate is high. Second, the more social welfare spending rate goes flat, the more elderly suicide rate is growing. Third, the more relative poverty rate (income inequality), increasing population aging rate, and elderly dependency ratio are high, elderly suicide rate goes high at the same time. Finally, this study proposed several socio-economic policy alternatives for preventing continuous growth of Korean elderly suicide rate.

본 연구는 스타트업 투자성과와 연계된 창업가 역량, 재무정보 등 정량데이터를 기반으로 스타트업 투자자들의 투자결정요인을 분석하였다. 주요 실증결과는 다음과 같다. 첫째, 창업 초기 종업원 수가 많고, 최고경영자의 지분비율이 높을수록 투자승인 확률이 높게 나타났다. 둘째, 재무적 특성에서는 기업의 매출액 규모가 작을수록 투자승인 확률이 높게 나타났다. 이러한 결과는 스타트업의 경우, 기업의 단기성과보다는 투자 결정에 있어 미래가치 혹은 다른 정성적인 요인이 더 고려된다는 점을 보여준다. 셋째, 창업가 특성에서는 CEO 교육수준(학력)이 높을수록 투자승인 확률이 높게 나타났다. 즉, 창업자의 학력은 성공적인 투자 여부에 핵심적인 변수이고 이것은 선행연구의 결과와 다르지 않았다. 또한, 학력과 투자유치의 연관성은 창업 3년 미만 스타트업에서 상대적으로 강하게 나타났다. 선행연구에서 투자정보공개, 관련 데이터 확보의 어려움으로 스타트업 투자에 관한 정량적 실증연구가 거의 진행되지 못한 점을 고려한다면, 본 연구는 설문조사 방식을 뛰어넘어 국내 초기 창업기업만을 대상으로 성공적인 투자유치와 연계된 스타트업의 평가요인을 정량적으로 분석했다는 점에서 중요한 의의를 갖는다.
