This study proposes a novel option strategy by using characteristic of volatility reversion and rough set algorithm in options market. Until now, various research has been conducted on stock and future markets, but minimal research has been done in options market. Particularly, research on the option trading strategy using high frequency data is limited. This study consists of two purposes. The first is to enjoy a profit using volatility reversion model when volatility gap is occurred. The second is to pursue a more stable profit by filtering inaccurate entry point through rough set algorithm. Since options market is affected by various elements like underlying assets, volatility and interest rate, the point of this study is to hedge elements except volatility and enjoy the profit following the volatility gap.

A company have to grow constantly. If a company does not grow and stagnant, it will be finally out of the market. The contemporary companies fully make use of M&A to search for new growth engines. The reason of companies using M&A as a important tool of a business strategy is the fastest way to achieve technology power, market power, competitiveness. The form of M&A was that leading companies take over smaller companies or merger and acquisition between small companies in the middle of 2000. But now, Mega mergers between industry leading companies often occur and especially domestic of course M&A of foreign companies occurs actively. These days the boom of stock market and the big companies are pouring on sale by restructuring, privatization and the basis of low interest will make the M&A market continuously. In this study, I suggest a solution of actual human resources management by analyzing proven M&A cases and search for various problems of a gap in the leadership and communication in connection with integration of organization culture after M&A. First of all, I arrange the theoretical concept of the subject and analyze the key factors of the success M&A cases, lastly I suggested a HR strategy after M&A. After M&A, HR strategy is ; First, a company have to build a organization culture which is that merger company accommodate a excellent organizational characteristic of predecessor company with consideration of culture difference. Second, M&A must proceed to remove of anxiety about the future and employment stability by excellent leaderships. Third, organization integration after M&A is influenced by the level of integration for that reason it was verified that M&A have to make progress by communication of each 2 organizations.

The purpose of this study is to test empirically the effects of Entry Barriers for the stock prices of Venture Business using the Ohlson Model which is modifying and extending in terms of growth and the potential growth energy. Because the traditional Ohlson model(1995) on which the firm's value is determined only based on abnormal earnings and book value have numerous limitations when we evaluate the value of venture Businesses with high technology and new emerging market. In order to overcome these limitations, We can introduce items of net sales growth ratios and industrial property-to-net asset ratios into as proxy variables of the growth and potential growth energy. In the process of analyzing these research tests, we have set three kinds of hypotheses and tested then empirically compared with KOSDAQ ordinary listing business and KOSDAQ venture businesses between long-term analysis and short-term analysis. According to the degree of concentration reflecting HHI index, our empirical research were performed in depth. Therefore, the results of this study show us that all three kinds of Hypotheses are accepted.

An attempt has been made in this article to discuss the fundamentals of technical analysis of the stock market. A retail investor or trader may not have the wherewithal to source that kind of information. Technical analysis requires a candlestick chart only. Most of the brokers in India provide charting solutions as well. Studying the price action of a security or commodity or Forex generally indicates a price pattern. Prices react at certain levels and widely known as support and resistance levels. Since whatever is happening with the price of the security is considered to be a part of a pattern or cycle which has already played out sometime in the past, these studies help a keen technical analyst to identify with certain probability, the future movement of the price. Study of the candlestick patterns, price action, volumes and indicators offer the opportunities to identify a high probability trade with probable target and a stop loss. A trader or investor can take high probability trade or position and control only her losses.

The aim of this study is to utilize system trading for making investment decisions and use technical analysis and Dynamic Time Warping (DTW) to determine similar patterns in the frequency of stock data and ascertain the optimal timing for trade. The study will examine some of the most common patterns in the futures market and use DTW in terms of their frequency (10, 30, 60 minutes, and daily) to discover similar patterns. The recognized similar patterns were verified by executing trade simulation after applying specific strategies to the technical indicators. The most profitable strategies among the set of strategies applied to common patterns were again applied to the similar patterns and the results from DTW pattern recognition were examined. The outcome produced useful information on determining the optimal timing for trade by using DTW pattern recognition through system trading, and by applying distinct strategies depending on data frequency.

Mezzanine products are financial investment products with both bond and stock characteristics, which are mainly issued by low-grade companies in the financial market to secure liquidity. Therefore, bondholders investing in mezzanine products must make decisions about when they want to convert to stocks, along with whether they invest in mezzanine products issued by the company. Therefore, in this paper, a total of 2,000 learning data and 200 predictive experimental data with stock conversion events completed by major industries are divided, and mezzanine event algorithms are designed and performance analyzed through artificial neural network models. This topic is meaningful in that it proposed a methodology to scientifically solve the difficulties of exercising mezzanine products, which are of high interest in the financial field, by applying artificial neural network technology.

Since 1970, China has become the biggest cocoon producer in the world, and made the highest historical record of cocoon output for 759,800 tons in 1995. However, in 1996 cocoon production reduced sharply to 470,900 tons. After a ten-year adjustment and reform, sericultural areas have shifted from developed regions to developing regions and from the east to the west. From 2000, the cocoon output has started to increase restoringly. By 2004 it recovered to 547,091 tons. With the development of market economy, sericulture management has been changed, including mulberry fields concentrated to the specializated households and cooperatives, cocoons produced in larger scale instead of individuals, Silkworm egg producing enterprises gradually changed into non-governmental joint-stock ones. The mechanism of market cocoon price has been gradually established. The management model of combination of trade, industry and agriculture is pushing and improving. It is the fruit of modern science and technology, especially sericultural basic research, that provides China's sericulture with the opportunity and vital force. China's sericulture, therefore, will continue to develop steadily in future.

사명은 기업의 정체성을 나타내는 가장 중요한 요소 중 하나이다. 사업영역 변경, 이미지 개선, 영문이름 정정 등 다양한 이유와 필요성 때문에 사명을 변경하는 기업들이 있다. 이러한 사명 변경을 하는 기업의 재무적 특성은 어떠할까에 대한 답을 찾고자 하는 것이 본 연구이다. 사명 변경에 대한 국내 연구는 매우 드물다. 일부 연구에서 사명 변경에 대한 증권시장의 반응에 대하여 분석한 경우가 있으며, 상호 변경이 영업성과에 미치는 영향을 검토한 적은 있다. 그러나 사명 변경 기업이 갖는 재무적 특성에 대한 연구는 전무한 실정이다. 본 연구는 사명 변경기업을 실험집단으로 하고 동종 산업내의 유사한 규모의 기업을 통제집단으로 하여 사명 변경 기업이 상대적으로 갖는 재무적 특성을 분석한다. 주요 재무적 특성으로는 수익성, 활동성, 유동성, 안전성, 성장성 등을 대상으로 하며, 각각의 특성 내에서 2-3개의 측정 변수를, 이론적인 토대하에 선정하여 그 특징을 분석한다.

우리나라 지역발전정책은 80년대 들어서 심화된 국토불균형 문제를 해소하기 위하여 지역경제 활성화 및 지방투자 촉진 목적의 다양한 정책 수단을 마련하면서 본격화 되었다. 수도권 소재 기업의 지방 이전을 위한 각종 법률과 제도가 제정 시행된 결과 일정 부분 성공했다는 평가가 있다. 충북지역 역시 수도권 소재 기업의 유치를 위하여 다양한 노력을 기울이고 있다. 이러한 중앙정부와 지방정부의 다양한 노력 결과, 2000년 이후에 충북으로 이전한 총수는 약 170여개 기업 정도가 되었다. 이들 기업은 업종별이나 지역별 등과 같은 그 구성 비율로 볼 때 고르지 못한 면이 있다. 예를 들어 기업의 지역별 이전기업 수를 보면 충주 46개, 청원 28개 기업으로 주로 충북 북부지역과 중부권에 집중되어 있고 영동과 보은 등의 남부권으로 이전한 기업은 거의 없어, 균형 개발 차원에서 남부 3군(옥천 포함)에 대한 충북도 차원의 지원이 필요할 것으로 보인다.
