인터넷의 진화에 따라 우리사회는 매우 빠르게 변화하고 있으며, 이러한 변화를 선도한 인터넷은 앞으로도 개인 맞춤형, 사물 지능화 등으로 진화를 거듭하여 우리 삶에 더욱 큰 변화를 가져올 것이다. 경제적 측면에서도 인터넷을 기반으로 한 다양한 형태의 융합이 산업발전의 새로운 패러다임으로 대두되어 전력, 교통 등 산업간 융합이 가속화되고, 첨단 융합보안기술로 고(高)부가가치 신규 시장의 창출이 가능해질 전망이다. 그러나 인터넷, IT의 발전과 더불어 사이버 공격의 특성이 과거 호기심이나 자기 과시적 행태에서 조직적이고 금전적인 이익을 노리는 방향으로 확산되고 있으며, 인터넷의 익명성과 비대면성으로 인해 불건전 정보의 유통, 저작권 침해, 명예 훼손, 언어폭력 등 개인과 사회의 피해가 점증하고 있는 상황이다. 본고에서는 이러한 환경변화에 맞추어 융합을 통한 가치 창조적 정책 및 선진 인터넷 기반마련, 깨끗하고 안전한 인터넷 이용환경 조성, 글로벌 협력체계 강화 등의 전략 목표 달성을 통해 신뢰할 수 있는 인터넷 및 방송통신융합의 가치창조와 진흥이라는 미션을 완수하기 위한 한국인터넷진흥원의 주요 중점 추진과제를 정리하였다.

본 연구에서는 TOD는 대중교통수단의 분담율 제고가 목적인데 이를 위한 정책대안의 모색에 필요한 새로운 분석기법을 제시하였다. 교통수단의 결정요인은 개인 특성과 라이프스타일 그리고 도시공간특성인데 이 요인들은 상호의존적으로 복합적 결합작용은 한다. 또한 개인과 그룹 및 지역 특성은 서로 다른 차원에서 상호의존성을 갖는다. 전통적 회귀분석과는 달리 위계적 분석모형은 요인들 간의 상호의존성과 복합결합적 영향관계를 규명하는 장점이 있다. 이러한 분석 기법에 의한 결과는 보다 효율적인 TOD정책 대한의 모색에 많은 기여를 할 것으로 기대된다.

Health promotion has more comprehensive approaches in recent years. Nevertheless we accept the concept of health promotion differently, we are agree on that community is the most important field in health promotion which includes population at the aspect of health policy, individual skill and, environment. And there are a number of different approaches to health promotion. In them, 'population approaches' and 'high -risk group approaches' has the most different characteristics. 'Population approaches' is equally important or more important than 'individual approaches' for maintaining and promoting population health. Almost part of this article contents is the summary of the guideline and population strategy of health promotion in Korea, 1999 - 2005. Community based health promotion program should be reinforced, integrated, comprehensive, collaborative through efficiently utilizing community resources. Recent new orientation of community health program is integrated health program, we can find this orientation at Ottawa charter 1986. Comprehensive approaches with the determinant factors for health are essential task. Physical activity is a key health determinant. The population-health approach suggests that educating people about physical activity is not enough. Individual behavior changes are important too, but need to be balanced with strategies for environmental change. Population strategy with physical activity for health promotion should be developed through improving social and physical supportive environment, linking and integrating community resources between public and private sectors in national, regional and local level. Continuous public education and social marketing should be provided through collaborating with community physical activity organization, facilities, work-places and school for increasing concern of all the people of community about physical activity. Governments, agencies and citizens should held and participate to building movement. And the strategy that various 'active for life' program should be developed, delivered, maintained and reinforced continuously. Basically, adequate and sufficient financing, developing human resources, policies and legislation would be provided and supported fully too. At last, research development and knowledge exchange are required domestically and internationally. In Korea, we had classified the category of strategic priority of physical activity programs by environmental support, life-course approach, high-risk group approach and disease group approach for physical activity program based on community health center. Community based core programs for physical activity that includes infrastructure building and establishment of supporting environment, community campaign, health promotion education and public service announcement, physical activity programs for elderly and obesity, exercise prescription program.

This paper examines whether angel investors affect startup's financial performance (profitability and growth ratios) in the Korean startup market over 10 years period from 2009 to 2018. In particular, we consider not only the behavior of angel investor such as the investment amount or the type of investments (stocks, bonds) but also the type of angle investor (individual or corporation). Our empirical results are as follows. First, we find that the startup's profitability ratios are higher after the investment of angel investors. However, the growth ratios show different results in assets and sales. Second, we identify that the investment amount of angel investors negatively affects on the startup's growth ratios. Lastly, we find that equity investment such as common stock or preferred stock and the individual angel investors such as personal investment association or professional angels show higher financial performance than bond investment or corporate angel investors. Overall, our findings imply that angel investors positively affect startup's financial performance. In particular, we infer that the superior financial performance is largely attributed to monitor startups by participating as shareholders or to select more carefully by the individual angel investors who may be exposed to more investment risk. In conclusion, our findings support that angel investors play a positive role in the Korean venture investment market.

Trust is a personal emotion that is affected by individual characteristics and social atmosphere. However, a lot of studies on government trust focus on government factors such as fairness and expertise of the government. Government trust is mainly affected by the capacity and characteristics of government. However, government trust is likely to have a significant impact by personal factors such as personal disposition and character. Therefore, this study examines whether government trust is influenced not only by government factors but also by personal factors such as individual values and general trust tendencies. The results of this study show that government trust is positively related to government factors such as government expertise and fairness. In addition, individual values and general trust tendencies, such as age, political tendency, happiness, prospects for the future, and corporate trust level, are also affecting government trust. This indicates that government trust is influenced not only by government variables such as government expertise and government fairness but also by individual values and trust tendencies. It suggests that government trust is not just a variable influenced by government behavior, but also related to individual values and trust tendencies.
