In this study, we conducted research on the automated trading of U.S. stocks through a volatility strategy using the Fear and Greed index. Volatility in the stock market is a common phenomenon that can lead to fluctuations in stock prices. Investors can capitalize on this volatility by implementing a strategy based on it, involving the buying and selling of stocks based on their expected level of volatility. The goal of this thesis is to investigate the effectiveness of the volatility strategy in generating profits in the stock market.This study employs a quantitative research methodology using secondary data from the stock market. The dataset comprises daily stock prices and daily volatility measures for the S&P 500 index stocks. Over a five-year period spanning from 2016 to 2020, the stocks were listed on the New York Stock Exchange (NYSE). The strategy involves purchasing stocks from the low volatility group and selling stocks from the high volatility group. The results indicate that the volatility strategy yields positive returns, with an average annual return of 9.2%, compared to the benchmark return of 7.5% for the sample period. Furthermore, the findings demonstrate that the strategy outperforms the benchmark return in four out of the five years within the sample period. Particularly noteworthy is the strategy's performance during periods of high market volatility, such as the COVID-19 pandemic in 2020, where it generated a return of 14.6%, as opposed to the benchmark return of 5.5%.

Since increase in energy consumption and environmental issues started to grab global attention, various countries have had their own supporting policy to promote supply of renewable energy which is a stable and eco-friendly energy source. This study analyses Korean Renewable Portfolio Standard by comparative analysis of current policies in major countries in respect of design components of a pragmatic industrial policy system, such as political leadership, policy coordination and consultative committee discussion, and policy enforcement with responsibility and transparency. This is to identify problems and to present political suggestions for successful management of the standard based on a fundamental concept of the pragmatism industrial policy. It is predicted that the strategic cooperation between a market and a government leads to industry development as the relationships of two parties are regarded not as antagonistic but as complementary.

This study analyzed existing patents related to real-time monitoring and detection technology for landslides on natural terrain. The purpose of patent analysis is to understand landslide hazard technology trends and to develop new advanced technology. This study searched patent data using key words related to landslide monitoring and detection in Korea, the USA, Japan, China (Hong Kong), Europe, and Taiwan. The patents were divided into five main categories and five to seven subcategories in each main category and analyzed by year, country, and applicants. The results were utilized to derive a portfolio of promising technologies for each country. The analysis results will also contribute to the development of more effective research strategies and to categorize research findings from previous studies on landslide hazards.

Offshore wind power has been extremely popular in recent years, and in the energy technology field, relevant research has been increasingly conducted. However, research regarding patent portfolios is still insufficient. The purpose of this research is to study the status of mainstream offshore wind power technology and patent portfolios and to investigate major assignees and countries to obtain a thorough understanding of the developmental trends of offshore wind power technology. The findings may be used by the government and industry for designing additional strategic development proposals. Data mining methods, such as multiple correspondence analyses and k-means clustering, were implemented to explore the competing technological and strategic-group relationships within the offshore wind power industry. The results indicate that the technological positions and patent portfolios of the countries and manufacturers are different. Additional technological development strategy recommendations were proposed for the offshore wind power industry.

브랜드 포트폴리오 전략에 따르면 브랜드의 수가 지나치게 많을 경우 브랜드를 지원할 자원은 부족하게 된다. 보령시는 머드를 외국으로부터 전량 수입하는 것에 착안하여 세계 5대 머드로 손꼽히는 대천 앞바다의 보령머드를 개발하여 화장품으로 상품화 하는데 성공하였다. 천연 및 유기농 등 자연주의 화장품에 대한 소비가 증가하여 유기농 화장품시장이 크게 성장함에 따라 보령머드화장품도 연관성이 높고, 차별화되고, 활력을 가진 브랜드를 만들어야 한다. 조사 결과, 소비자의 개성과 시대의 트렌드에 부합하려는 보령머드화장품의 노력은 브랜드의 선택과 집중이 판매형식(시판, 장판, 특판, 방판)에 따라서 고객세분화 되어 있다는 것에서 잘 나타나고 있다. 이를 바탕으로 한정된 자원의 효율적 분배를 통한 제품 개발이 이루어지고 있음을 알 수 있다.

We consider a consumption and investment problem where an investor's investment opportunity gets enlarged when she becomes rich enough, i.e., when her wealth touches a critical level. We derive optimal consumption and investment rules assuming that the investor has a time-separable von Neumann-Morgenstern utility function. An interesting feature of optimal rules is that the investor consumes less and takes more risk in risky assets if the investor expects that she will have a better investment opportunity when her wealth reaches a critical level.

기업성과에 미치는 정보기술의 전략적 영향력이 높다는 인식으로 인해, 많은 기업들이 정보기술에 대한 투자를 증대하고 있다. 하지만, 정보기술전략과 정보기술 성과간의 관계를 직접적으로 규명한 실증연구는 찾아보기 힘들다. 본 연구에서는 정보기술에 의한 성과가 다르게 나타나는 원인이 기업이 정보기술로부터 얻고자 하는 전략적 목표가 다르기 때문이고 서로 다른 목표에 의해 정보기술의 투자 방향이 다르게 나타난다는 것이 초점을 맞추고자 한다. 따라서 본 영구는 다음과 같은 연구문제를 도출하였다. 1) 정보기술전략은 정보기술성과 간의 관계를 규명하는데 본 연구의 목적이 있으며, 이를 통해 정보기술성과가 다르게 나타나는 현상을 설명하고자 한다.

In this paper we study consumption-labor supply decision of an agent who prepares for retirement at a known time in the future. The agent is assumed to have a preference which is represented by the von Neumann-Morgenstern utility function in which the felicity function has constant relative risk aversion over the composite of consumption and leisure. The composite is obtained by the Cobb-Douglas function. A general problem has been studied by Bodie et al. (2004). We contribute to the literature by deriving the Slutsky equations and conducting comparative statics. In particular, we show that wealth effect can exhibit an interesting property depending upon the time until retirement, as the interest rate increases.

This paper conducted an analysis of economic effects of offshore wind power in Korea with benefit/cost analysis. The existing feed-on tariff, which was too low to support wind power development, was recently replaced with a Renewable Portfolio Standard(RPS), effective from 2012. According to the new regulatory policy, The Korean government has announced a strategy to draw investments worth for offshore wind farms with a total capacity of 2.5 GW over the next eight years, which is expected the change of cost and benefit. After overview the offshore wind power development status, The effects on cost can be divided by economic, environmental and social factors. Each factor will be calculated and combined by both evaluating index and using Quantification methods. At the end, the implication for the evaluation of feasibility of offshore wind power of Korea will be done.
