Unlike existing other industries, the knowledge-based industry has the potential to grow increasingly with factor input unlimited. Importance of investigating knowledge and information evaluation cannot be overemphasized to promote economic development in that knowledge and information is accepted as an engine of new economy. We attempt to define the scope and value of knowledge and information and develop the knowledge and information value model. The results help policy-makers to manage and evaluate the knowledge and information with useful and responsible information.

물이 상품에 내재되어 국가간 이동을 한다는 가상수 개념은 기후변화로 인해 물부족 현상이 심화되면서 세계 각국의 관심을 얻고 있다. 향후 물부족 현상 및 가상수 이동과 관련해 국제적인 물거래에 대한 전세계적 차원의 조치가 있을 가능성이 예상되면서 가상수의 국제적인 이동 추이에 대한 연구가 이루어지고 있다. 그럼에도 불구하고 가상수 교역에 영향을 미치는 요인이 무엇인지에 대한 연구는 아직 미비하다. 따라서 본 연구는 가상수 이동에 영향을 미치는 요인을 사회경제적 요인을 중심으로 탐색한다. 사회경제적요인으로서 국가의 경제위기 경험 유무, 경제규모, 생활수준, 경제성장속도, 그리고 수자원 정책기조를 선정하고, 이러한 요인들이 전세계국가 및 한국의 가상수 교역량 변화에 어느 정도나 영향을 미치는 지를 분석했다. 가상수 교역량에 대한 자료는 UNESCO, UN, FAO의 자료를 토대로 데이터셋을 구축해 활용했다. 총 10개 농축산 품목을 대상으로 산정한 가상수 교역량에 대해 1989년부터 2013년까지 총 24년간의 자료를 분석했다. 분석 결과 아시아 외환위기, 미국발 경제위기 등 세계적 수준의 경제위기는 전반적으로 가상수 교역추이에 큰 영향을 미치지는 않았으나, 미국발 경제위기는 가상수 교역흐름 완화와 일정 정도 관련성을 보였다는 사실을 알 수 있었다. 경제규모와 가상수 교역량은 전반적으로 높은 상관관계를 보였으며, 한국의 경우에는 경제규모 및 생활수준 모두 가상수 교역량과 높은 상관관계를 보였다. 반면 경제성장속도는 가상수 교역량과 큰 상관관계를 보이지 않았다. 시간적으로 보았을 때 한국의 경우 생활수준은 2007년도 이후에 가상수 교역량과 매우 큰 상관관계를 보였다. 경제적 요인, 특히 경제규모가 가상수 교역량과 높은 관계를 보이는 것은 경제력이 상승하면서 생활습관이 변화해 육류소비가 많은 것과도 관련이 있는 것으로 분석되었다. 사회적 요인과 관련해 분석한 수자원 정책의 기조변화는 가상수 교역량 변화에 영향을 미치지 않는 것으로 나타났다.

This study aimed to analyze the association among dental care consumers' responses to waiting time, hospital image, and patient satisfaction and provide basic data that could help qualitative waiting conditions management related to health care service. A survey was conducted from May 18 to June 20, 2016 in adults who had spent waiting time at dental hospitals or clinics, and the following conclusion was drawn: Hospital image was associated with the changes in reliance on dental care centers in case of long wait, the changes in reuse intentions, and the reservation system, and patient satisfaction was associated with gender, explanation of expected waiting time, the changes in reliance on dental care centers in case of long wait, the changes in reuse intentions, and the reservation system. The positive responses to waiting time was positively correlated with hospital image and patient satisfaction; the negative reaction to waiting time was negatively correlated with hospital image and patient satisfaction; and hospital image was positively correlated with patient satisfaction.

This paper examines the discussion on the income-led growth known as the core economic strategy of Moon's administration in terms of Korean welfare regime. Although the income-led growth strategies have presented various issues, the income-led growth strategy seems to be a timely alternative discourse that emphasizes the demand side, considering supply-oriented growth strategies have caused long-term recession and deepening of inequality. It is important that the income-led growth strategy places social expenditures as an important growth engine for virtuous cycle of production and consumption. However, this paper has confirmed that simply raising wages and increasing social expenditure do not increase the aggregate demand and production. Moreover, empirical studies have shown that the inclusion of external sectors and liabilities into the analysis weakens the wage-led growth of the Korean economy. For this reason, this study concluded that the government's sophisticated policy intervention is necessary for the increase of real wages and social spending to be economic growth.

OECD countries have been stimulating private pensions instead of public pensions because the financial stability of public pensions has been threatened by the aging population. Korea, which has the fastest aging population in the world, has been following the recommended policies of major countries. Unlike major economies, however, most of Korea's household assets are composed of real estate assets. Due to the economic and social importance of real estate assets in Korea, the wealth effect of real estate has been used as a major tool in macroeconomic policy. This study analyzed the effect of real estate value changes on the contribution of private pensions (personal pension + retirement pension). Utilizing a two-way, fixed effect model with the balanced panel data of the National Survey of Tax and Benefit, empirical results presented that the private pension contribution increased by 0.171% when the value of real estate increased by 1%. Thus, real estate value changes were analyzed as positive for retirement preparation through private pension. These results suggested that if the real estate market would shrink in the future, consumption would decrease, and the degree of preparation for retirement might be smaller.

This research examines how IoT makes a significant contribution to the innovation of media firms. The media firms will be able to find new reveue sources and strengthen firms' competence through innovating product, process and business model. While IoT increases the experience of interactivity and immersion for consumption, it improves the way ads are exposed and its impact is measured, leading to revenue increase. For these benefits fulfilled, innovation friendly media eco-system must be established. It is the most critical that media firms should change skeptical attitude toward IoT's potential and actively invest it to employ IoT. The government should create regulatory framework to best utilize the innovative advantages of IoT.

The aim of this article is to introduce articles of the special issue on 'Revitalization Conditions on Crisis on Industrial Regions: Experience from Europe and the Republic of Korea, and to explore policy alternatives to crisis on industrial regions on the basis of policy diagnoses and prescriptions. In the existing research, diagnoses of such Korean regions are quantitatively focused upon industry, employment, plant, consumption, investment, real estate, and labour market, and are qualitatively based upon external environment and functional, structural and spatial characteristics. Prescriptions of such regions emphasize the establishment of a law and an institutional fix, financial supports, jobs' creation, industrial diversification, the intensification of urban foundation throughout the urban revitalizaion. In the policy development for these regions, it is required to link the industrial sector to social, educational, political and welfare sectors, and furthermore the collaboration of inter- and intra-ministry and the active participation of provincial and local governments are needed.

Japanese economy suffered from a great recession for one decade between 1993 and 2002, because of the bubble bursting. Recently, a similar situation broke out in the USA and spread throughout the world. This paper investigated the effects of economic policy on the Japanese depression in order to find out how the recession, caused by financial crisis, can be reasonably removed. The analysis of documentary records indicate that there exists an optimum rate in government debt and the point in time of economic policy is decisive. Statistical studies with a VAR model and a State Space Model suggest that government expenditures affect the growth rate of national product but with a short term and it has a time lag of a half year. Income tax has a grievous negative effect on the growth rate with a long term and it works without a time lag. Therefore the increasing of taxation should be put into force very carefully. However private investment is a determinate factor for the recovery of depression.

Wisdom Contents are created with experiences and ideas of multiple authors, and consumed in Internet based Social Network Services that are not subjected to regional restrictions. Existing copyright management systems are designed for the protection of professional authors' rights, and effective in domestic area. On the contrary, the blockchain protocol is subjected to the service and the block is added by the consensus of participating nodes. If the data is stored to the blockchain, it cannot be modified or deleted. In this paper, we propose the blockchain based undeniable multi-signature scheme for the protection of multiple authorship on Wizdom Contents. The proposed scheme is consisted of co-authors' common public key generation, multi-signature generation and verification protocols. In the undeniable signature scheme, the signature cannot be verified without help of the signer. The proposed scheme is best suited to the contents purchase protocol. All co-authors cannot deny the fairness of the automated profit distribution through the verification of multiple authorship on Wizdom Contents.
