This study is to suggest some improvement directions of the criteria for the management evaluation in order to contribute to the achievement of lasting value of the continuous development and publicity in regard to the public library means-efficiency. To this end, This study analyzed the means-efficiency evaluation criteria via theoretical review on business analysis of private enterprise and the analysis framework based on it. The improvement of evaluation criteria in regard to efficiency for the continuous development of public library are as follows. 1) Regardless of domestic and foreign, an efficiency index in the performance evaluation index of public library is absolutely insufficient. The sufficient indexes measuring efficiency which is appropriate for the concept of performance should be developed. 2) A flow data representing input and performance in certain time period is insufficient. Therefore, evaluation index consisted of flow data should be more developed. 3) Long term stock data is excluded in the term cost as it is the cost used for the long term such as fixed assets. However, it is useful as input data, which is realized through the perfect accounting.

Volatility Index is the index that represents future volatility of underlying asset implied in option price and expected value of market that measures the possibility of stock price's change expected by investors. The Korea Exchange announces a volatility Index, VKOSPI, since April, 13, 2009. This paper used daily data from January, 2002 through December, 2008 and tested power of Volatility index for future returns of portfolios sorted by size, book-to-market equity and beta. As a result, VKOSPI has the predictive power to future returns and then VKOSPI may be determinants of returns. Also if beta is included when sorting portfolio, the predictive power of VKOSPI is stronger for future portfolio returns.

In Korea, a cooperation charge on conservation of ecosystem is imposed to prevent indiscriminate development. The total amount of this charge is determined by multiplying the size of the destroyed area by a value per unit area and the area index within 5 billion won. Since 2001, the charge per unit area has been determined to be $250won/m^2$. In this study, we estimated the unit value of ecosystem services per year using benefit transfer method, with a focus on forest resources. According to our results, forest resources have a value of about $3,500won/m^2$ per year. When the non-use value is subtracted, that figure becomes approximately $1,300won/m^2$. If this value incorporates the unit value of the cooperation charge on conservation of ecosystem, it will increase. To comply with the original intent of the cooperation charge on conservation of ecosystem, the fund must be used to improve ecosystem services, including the restoration of a destroyed area or the purchase of new land.

With development of Information Security industry and recognizing value of information as an asset, demand for information protection is foreseen to be expanding gradually. The Information Security industry in this paper defines as an industry where relative products as well as consulting services are developed, produced, and distributed. This study reclassifies sub-sectors of the Information Security industry based on the definition of product and services defined above, and it uses the RAS technique to broaden a scope of an input-output table to include the Information Security industry with purpose of analyzing economic spill-over effects industry will encounter during 2013~2017. Results show that investment in the Information Security industry during 2013-2017 induces total economic outputs to KRW 3,206.9 billion and is expected to employ additional 27,406 workforce.

In the phono-sapiens era of the intelligence information society, most business activities are increasingly dependent on networks and information systems. SMEs, which occupy the majority of Korean companies, are increasingly possessing the value and technology of their information assets, and their ability to protect core technologies that are the driving force of corporate growth will be the most important competitiveness of enterprises. Accordingly, the Ministry of Science and ICT and the Korea Internet & Security Agency(KISA) provides a foundation for minimizing the damage from cyber threats such as hacking and information leakage by evaluating the current information protection level of SMEs and enhancing information protection capability by supporting a high level of customized information protection consulting. In this study, we analyze the effectiveness of information protection based on the results of KISA SMEs consulting. In addition, by identifying problems and limitations derived from SMEs information protection consulting results, SMEs should propose measures to improve information security of SMEs that can manage information protection management system more efficiently and effectively.

최근 기후변화로 인한 수문기상학적인 극한 사상들은 점점 대형화되고 있고, 그 발생빈도 또한 잦아지고 있다. 인구의 증가와 급격한 도시화, 자산 가치의 증가 등으로 물과 관련된 재해로 인한 피해는 점점 더 규모가 커지고 있다. 홍수와 가뭄, 허리케인, 쓰나미와 같이 물과 관련된 재해는 그 영향을 받는 사람들의 수로 본다면 지구상의 재해 중 90%를 차지하고 있을 만큼 그 규모가 크다 할 수 있으며, 전세계적으로 물관련 재해로 인한 재산상의 피해를 약 1,000억 달러 규모로 추산하고 있는데, 2030년에는 그 현재의 두 배가 될 것으로 예측하고 있다. 이와 같은 재해로 인한 피해는 개도국이나 최빈국뿐만 아니라 관련 인프라가 잘 구축되어 있는 선진국 또한 예외는 아니다. 2015년 9월 UN 세계지속가능 정상 회의에서 각국의 수반들 또한 17개의 "지속가능개발목표(Sustainable Development Goals; SDGs)"를 채택함으로서 post-2015 아젠다가 세계를 지속가능하고 균형 있게 바꾸어 나가기 위해서 취해야 하는 가장 시급하고 필요한 과감한 혁신적인 조치임을 인식하였다. 재해경감과 지속가능개발은 2005년 채택된 "효고프레임웍(Hyogo Framework for Action) 2005-2015"에서 도 중요하게 다루어 졌다. 2015년 3월 제3차 세계재해경감대회에서 채택된 "센다이 프레임웍(Sendai Framework for Disaster Risk Reduction) 2015-2030"은 Post-2015 개발의제의 첫 번째 합의 결의안이라 할 수 있으며, 인명피해의 실질적인 감소와 재해에 의한 영향으로 피해 보는 사람들의 수를 줄이고, 경제적 손실과 대형 인프라 피해의 경감을 주요 타겟으로 하고 있다. 이와 같은 리질리언스의 중요성은 SDGs의 Goal 11인 "안전하고 지속가능한 도시와 정주지 조성(Make cities and human settlements inclusive, safe, resilient and sustainable)"에서 강조되고 있을 뿐만 아니라 다양한 골에서 재해로 부터의 리질리언스 확보에 대한 필요성을 강조하고 있다. 재해 위험을 경감시키기 위해서 국제적으로, 지역적으로 또는 국경을 넘어서는 협력 관계의 구축이 중앙정부나 지방정부를 비롯한 국가적으로 절대적으로 필요한 노력이라 할 수 있다. 특히나, Post-2015 개발 아젠다에 대한 기후변화와 재해경감을 위한 금융지원을 포함한 최빈국, 개도국, 군소 도서국가들과 중견국 선진국들의 양자간이나 다자간 협력 채널을 통한 역량 강화가 필요하다.

Hallyu pop-culture contents which has influenced the world has sufficient preservation value as a cultural asset. However, there is still a lack of awareness of long-term preservation of Hallyu pop-culture contents and digital archiving is not in full swing, too. We requires accurate understanding of the concept, characteristics, format, media, and relationship of contents for digital archiving of Hallyu pop-culture content. Thus, this study analyzed and organized the concept, characteristics, and preservation subject of Hallyu pop-culture contents, as basic study for digital archiving of Hallyu pop-culture contents. In addition, we investigated the current status of digital archives (systems/institutions) of Hallyu pop-culture contents and Hallyu pop-culture contents, and presented basic proposal based on the problem factors.

The frequency and severity of damage caused by extreme climate events are increasing due to climate change. If the infrastructure is not prepared for the risks of climate change, property loss may occur in the facility itself and its surrounding areas. Therefore, climate change adaptation technology should be introduced to reduce future losses. Policy makers need to understand the economic impacts of each technology in order to select an appropriate option. Both the primary damage, which is the direct damage to the facility, and the secondary damage, which is the damage to the surrounding area due to climate change, should all be identified for understanding the economic impact from adaptation. This paper presents a procedure for deriving primary and secondary damage reductions from introducing adaptation technologies and suggests a methodology for evaluating adaptation technology specific to each infrastructure.

Non-fungible tokens (NFTs) have the advantage of being able to reliably manage details after minting, but how can ideas be protected before being converted to NFTs? The use of NFTs to increase the value of digital assets is increasing, but the problem of creating and selling NFTs without the consent of the creator is also increasing. Existing methods for protecting creators include a method of using a traditional authentication system and a method of using a social network, but each has limitations. Therefore, in this study, an identity token utilization method is proposed as a way to supplement the existing limitations. When an identity token is used, a certified NFT is issued through an existing identity authentication authority, so the verification of the authenticity of the token becomes clear. In addition, in inheritance and transfer, it becomes possible to respond to legal problems related to the transfer of creative rights.
