In Korea, the standard for calculating the profit of a general insurance, which constitutes the loading in the premium, is not specified, and most of the non-life insurance companies reflect 2~5% of the premium as profit margin. Although the transparency of pricing is required due to the nature of insurance products, there are insufficient standards and empirical studies on the determination of insurance price factors in the domestic insurance industry. In this study, we propose a method of calculating the expected profit margin of general insurance. A way for calculating the expected profit margin of the general insurance is to reflect the shareholder demand on the capital that the insurance company should secure against the risk of loss due to the profit/loss volatility, as a ratio to the insurance premium. Shareholders should be compensated for the risks associated with their insurance operations, and the opportunity cost of these shareholders is to be reflected in premiums. In this study, we calculate the amount of capital that the company should accumulate to prepare insurance risk for each product, and insurance risk is defined as the volatility of insurance operating profit/loss. And insurance risk is calculated using stochastic simulation based on Dynamic Financial Analysis (DFA) methodology. Finally, we calculate the expected profit margins for 25 products and analyzed the difference between those and the profit ratio of domestic general insurance.

In the context of domestic consumption environment changes such as expansion of smartphones and increase of single-person households, hypermarket, which was the mainstream of the existing retail market, have recorded negative growth for the last three years due to declining sales. And it is not enough to analyze the influence relationship with other retail channels or investigate the cause of consumption movement. In this study, we analyzed the decline in the growth rate of hypermarket by demographic variables, consumption time, etc. And logistic regression analysis revealed the relationship between the decrease in consumption of hypermarket and the change in the proportion of sales of other retail channels. In addition, we surveyed consumers who have decreased consumption of hypermarket based on actual card consumption data to determine why they choose different retail channels. This is significant in that the result of quantitative analysis of changes in retail channel consumption and the result of qualitative reasoning converged to give a stereoscopic view of consumption.

This paper investigates the value relevance of advertising activity over the period from 2001 to 2009 in the listed Korean stock markets(KOSPI and KOSDAQ). In addition, this paper divide all sample firm into several subsample, based on R&D intensity and export ratio in total sales. The empirical result of this paper shows following two evidence; First, advertising intensity, which proxies for advertising activity, is significantly related to firm value at the 1% level of significance. Second, advertising activity of high R&D intensity and high export ratio sample firms has more significant value relevance than for firms with low R&D intensity and low export ratio. The empirical results suggest that moderation effect of R&D intensity and export ratio are very important factor in determining the value relevance of advertising activity.

This study performed Panel Regression Analysis (PRA) with the debt ratio as a dependent variable and the ROE (return on equity), sales volume, current ratio, total capital, and Shanghai Containerized Freight Index (SCFI) as an independent variable. According to the GLS analysis, the current ratio to liabilities ratio was negative, and for sales, the ratio of liabilities was positive. Capital totals also had a negative impact on the debt ratio. However, ROE, unlike the hypothesis, had negative effects on the liability ratio, and the SCFI index was not significant. As implications of this research, the company confirmed that its sales increased as the debt ratio of global shipping companies rose, achieving economies of scale. However, it was confirmed that the actual size of the economy through the injection of other capital would help increase sales but not affect net profit. Shipping companies should expand their business power and secure large container vessels to secure credibility of shippers. In the future research, an analysis considering exchange rate, global economic growth rate, and manufacturing production index is needed.

This paper analyzes the firms value and the business performance before and after Chinese firms got listed in the U.S. First of all, it was separated into term before U.S listed and after listed, and looked whether there was any change in the Tobin'Q. After listed, as time went on Tobin'Q decreased more. In terms of net sales growth rate, it dropped significantly after U.S IPO. Operating profits and net profits rate increased more after being listed in large corporation, but in small corporation cases, it produced an opposite effect on debt ratio and net interest cost. Interest burden continued to fall after being listed in small corporation, and it couldn't find the investment profitability, nor could it utilize ROE, ROI variable. ROE, ROI continued to fall after being listed, but current ratio and quick ratio increased significantly in small corporation. From this results, we can infer that the financial liquidity showed signs of improvement after being listed.

This study suggests architect specialty contractors' strategies by interaction analysis between construction business indicators and business performance indicators. To do this, a database was compiled for construction orders and business performance indicators of specialty contractors with KRW 7 bil. or more of assets of 1997 through 2010. The causal relationship verification and actual proof-oriented analysis were performed for architect specialty contractors. The result is analyzed that their turnover ratio of total liabilities and net worth are affecting obtention of construction orders, ultimately increasing the operating profits. Therefore, this type of specialty contractors is determined to be able to secure corporate stability by establishing a specific operation plan for the total assets.

This paper describes a method that extracts the region of car-licence plates in color images of private and commercial cars. To extract car-licence plates, we use the feature that car-licence plate regions have regular colors according to the kinds of cars. In this paper, we propose the method that combines H component of HSI color model and Q component of YIQ color model. To improve efficiency of the process, we cxplore lines ill a car image by a regular interval in a bottom-up style. As a result, the extraction rates by only H-component. only by Q- component. and by combined Hand Q, are 53.6%, 82.1%, and 94.6% respectively.

이제 커피자동판매기에서 국내산 차를 판매하지 않아도 된다. 현행 커피자판기에 국내산 차를 강제적으로 1/3 이상 적용 판매하라는 규정이 삭제되게 되는 것이다. 보건복지부 식품정책과는 7월 19일 이같은 내용을 담은 "식품위생법 시행령 및 시행규칙" 개정안을 입법예고 했다. 이번 개정안이 마련된게 된 것은 한국자동판매기 공업협회의 적극적인 개정건의 작업의 결과이다. 한국자동판매기공업협회는 커피자판기 국내산 차 판매로 인한 여러 문제점들과 민원이 야기되자, 지난 2009년 11월초 보건복지부 식품정책과를 대상으로 "다류 식품자동판매기 국내산 차 의무 판매 규정"을 삭제해 줄 것을 개정 건의한 바 있다. 협회는 대형 커피자판기의 경우 커피의 판매 규정이 국내산 차 1/3 이상이어야 한다는 의무규정으로 인해 단일 커피자판기에도 싫든 좋든 국내산 차를 적용 판매함으로서 자판기 운영에 있어 큰 애로점으로 작용해 왔다고 주장했다. 또한 국내산 차 적용 판매가 소비자들에서 위생에 대한 취약성을 더 노출시킨다는 사실을 적극 어필을 했다. 이같은 협회의 주장을 보건복지부 식품정책과는 합리적으로 수용했다. 커피자판기의 국내산 차 적용 판매가 영업의 재량권만 침해할 뿐 규제 명분을 상실했다고 판단했다. 또 서울시나 식약청의 자판기 위생검사시에 상대적으로 국내산 차의 불량률이 높게 나타난 점도 주요인으로 작용했다. 이번 국내산 차 판매 의무 조항 삭제 입법예고로 커피자판기 시장은 새로운 흐름이 주도될 수 있을 것으로 보여진다. 업계에서 원하지 않는 조항이 삭제된 만큼 커피자판기 시장 활성화에도 적지 않은 도움을 주리라 기대된다. 이번에 입법예고된 개정안을 세부적으로 살펴보고, 과연 시장에 어떠한 긍정적 영향들을 미칠지를 분석해 봤다.

Intangible Assets are more important determinants of firm value than others in a digital information-based economy(Lev, 2001). Prior research reveals that investments in intangible assets such as R&D and advertising expenditures are associated with firm value. This paper examines the effects of the corporate investments in the information technologies(IT) on stock return and economic goodwill. The sample consists of 152 firms listed on the Korean stock market in 2002. To test hypothesis We employed multiple regression models. Results are as follows; First, IT environment, IT process, and IT human resource are positively associated with firm's IT value. Second, firm's IT value is positively correlated with firm's economic goodwill. Third, firm's IT value is positively correlated with firm's stock return. These results suggest that the investments related with IT are effective in cultivating firm's value and Stock investors can make the best use of firm's announcements related with IT value. Thus the authorities concerned need to expand the public announcements related IT value.
