본 연구의 주요 목표는 정보기술보안(IT security) 관련 투자의 경제적 특성을 조사하고 기업 내 최적의 정보기술보안 자원의 제공을 위한 대체적인 메커니즘을 비교하는데 있다. 정보기술 보안의 최적 수준과 기업 내 다양한 사용자 간의 비용분담 방식에 대한 중요한 의사결정에 유용한 지침을 제공하는 경제적인 연구는 많지 않다. 이에 대한 기초연구로서, 본 연구는 첫째, 정보기술 보안 자원이 소비의 비경합성(nonrivalry)과 혜택의 비배재성(nonexcludability)이라는 순수공공재(pure public goods)의 특성을 공유하고 있다는 것을 설명한다. 또한, 정보기술보안 제공은 개인사용자의 정보보안자원의 가치평가에 있어서 정보 비대칭성의 문제를 갖고 있다. 분석적인 틀을 통하여, 본 연구는 개별적인 효용극대화 방식은 기업 전체에서의 효율적인 제공 조건을 반드시 충족하는 것은 아니라는 것을 보여준다. 즉, 개별적인 방식은 비최적(suboptimal)의 방안, 특히 정보기술보안 자원이 부족한 수준에서 제공되는 결과를 초래한다. 이러한 문제는 무임승차(free-riding) 문제로도 알려져 있는 순수공공재의 비배재성이라는 특성에 주로 기인한다. 집단적인 의사결정의 근본적인 문제는 진실한 정보의 표출을 유도하고 정보비칭적인 구조에서 최적수준의 정보자원보안 관련 재화를 선택하는 메커니즘의 설계에 있다. 본 연구는 정보기술보안 자원의 제공이라는 문제 안에서 세 가지 대체적인 수요현시메커니즘(demand-revealing mechanisms), 즉 클락-그로브즈 메커니즘(Clarke-Groves mechanism), 기대효용 극대와 메커니즘(expected utility maximizing mechanism), 그로브즈-레야드 메커니즘(Groves-Ledyard mechanism)을 비교 분석한다 이 메커니즘들의 주요 특성이 각 메커니즘의 장점, 단점, 실제 다양한 적용가능성과 함께 논의된다. 마지막으로, 본 연구의 한계와 미래 연구 방향이 논의된다.

Innovation plays a large role in green growth. While it is a widely accepted view that, without innovation, it would be very difficult and costly to address major environmental issues, innovation itself tends to be constrained by limited access to eco-financing and is inherently risky, often requiring a long-term horizon. Although global consensus is more or less established as to the urgency and necessity of accelerating green innovation, the quality and quantity of financing in this area is largely insufficient, with increasing funding gaps in many countries. A new financial mechanism is urgently needed in order to re-orient financial flow and enable innovators to overcome the valleys of death that occur throughout the innovation cycle. A number of different modalities exist in financing the commercialisation of eco-innovation. Existing mechanisms have not been as successful as expected, revealing critical limits to furthering certain types of projects that are essential for economic and environmental progress. Experts' estimations have shown that the funding gap will widen in the coming years as demand for clean energy and green infrastructure rises, and as green technologies and innovation develop faster than the market for it can develop. Against this backdrop, the main purpose of this research is threefold: to identify issues and problems regarding current means of funding for eco-innovation and green projects; to provide insight into securing longterm green financing by looking at European cases; and ultimately to suggest policy implications for designing and implementing eco-specific financial instruments, focusing on governments' roles in sustainable financing for eco-innovation. This study analyses different models of financing mechanisms, a mix of public and private funds, in view of suggesting conditions for the sustainable financing of green projects, especially for large-scale high-risk projects. Based on the findings from the analyses of mechanisms and the shortcomings of the existing funding modalities, this study ultimately suggests policy implications for effectively supporting the commercialisation of eco-innovation.

Diabetes represents a serious health problem. In the diabetic state, alterations in metabolism, increased susceptibility to infections and immunological changes occur. The suppression of the immune response has been identified as a relevant factor that contributes to the increase in the rate of infections in these patients. At the same time, breast cancer is the most frequent malignant tumor in women. The molecular and cellular mechanisms underlying cancer development have revealed that immune cells functionally regulate epithelial cancer development and progression. Breastfeeding has been hypothesized to reduce the risk of breast cancer. However, early systematic reviews have not yielded consistent findings for this association. The demand for human milk is increasing due to the promotion and consumer acceptance of the health benefits of consuming a natural product rich in bioactive components. However, due to changes in glucose metabolism, the components of the milk from diabetic women are modified depending on the time of evaluation. In this literature review, we summarize important new findings revealing the paradoxical role of breastfeeding in preventing the onset of breast cancer in diabetic mothers. We hypothesized that the milk component production in diabetic mothers is affected by changes in glucose metabolism. Therefore, adequate maternal glycemic control and an adequate duration of breastfeeding for diabetic mothers are crucial to ensure that the immunity components are able to confer protection against breast cancer.
