In this paper, a continuous-time risk process in an insurance business is considered, where the premium rate is constant and the claim process forms a compound Poisson process. We say that a ruin occurs if the surplus of the risk process becomes negative. It is practically impossible to calculate analytically the ruin probability because the theoretical formula of the ruin probability contains the recursive convolutions and infinite sum. Hence, many authors have suggested approximation formulas of the ruin probability. We introduce a new approximation formula of the ruin probability which extends the well-known De Vylder's and exponential approximation formulas. We compare our approximation formula with the existing ones and show numerically that our approximation formula gives closer values to the true ruin probability in most cases.

옛부터 국내 재래닭은 우리나라 국민들의 식성에 알맞는 독특한 맛과 육질로 인하여 가든이나 토속 음식점 등에서 고가로 판매되면서 입지를 굳혀오고 있다. 일부 지역에서는 지역 특성에 맞는 브랜드를 상품등록하여 소비자들로부터 신뢰를 받는 농가들도 늘어가고 있다. 이런 가운데 축산연구소(소장 윤상기)에서는 빠르면 금년말 국내 순수 혈통을 자랑하는 재래닭이 상품등록을 마치고 공식 탄생할 예정이다. 축산연구소 가금과(과장 이덕수)는 이미 10년에 걸친 재래닭 복원작업을 마치고 3월중 특허청에 재래닭 3개 계통(흑색, 황갈색, 적갈색)에 대해 등록출원 준비를 마친 상태이다. 상표등록이 이루어질 경우 철저한 가계선발과 사양관리를 통해 고정된 국내 유일의 재래닭을 국제적으로 알리고 국내 소비자들에게 재래닭의 참맛을 전달하게 될 것으로 기대를 모으고 있다.

최근 한국사회에서는 웰빙 열풍이 불고 있다. 건강한 육체와 정신을 추구하는 생활로 일반적으로 이해되고 있는 웰빙은 아직 학문학적으로나 공식적으로 그 정확한 개념이 정의되지는 않았지만 건강과 즐거움을 최고 가치로 명분이나 형식보다는 실속을 추구하는 신세대 젊은이들을 중심으로 하는 웰빙 열풍은 아주 다양한 상품이나 서비스 분야에서 기업들로 하여금 새로운 제품들을 개발하여 이러한 웰빙 바람에 대응하도록 하고 있다.<중략>

The significance of leisure activities is highlighted, and professional baseball games, which featured the 2008 Beijing Olympics gold medal, are very popular. In recent years, along with the revenue from broadcasting, the club has been trying to gain revenue by developing various licensing products and merchandising products. However, sports related products are more advanced than Japanese professional baseball teams in Korea, and there is a lot of revenue from product sales. We want to compare the difference between the two countries sales of their products.

The study begins with the proposition that customers' recognition of risk and their information level for a service firm and its product influence to the selection of information channel and loyalty of customers. Experimental study found that the likelihood of personal information channel selection would be increased as customers felt higher level of risk and as they had lower level of information when they purchased service products. The study also found that customer loyalty would be influenced by the risk recognition level, but the relationship between loyalty and information level was not significant.

Equity-indexed annuities(EIAs) provide their customers with the greater of either the return linked to the underlying index or the minimum guaranteed return. Insurance companies have developed EIAs to attract customers reluctant to buy traditional fixed annuities because of low returns and also reluctant to buy mutual funds for fear of the high volatility in the stock market. This paper proposes a new type of EIA embedded with an outside barrier option with flexible monitoring period in order to increase its participation rate. It also derives an explicit pricing formula for this proposed product, and discusses numerical examples to show relationships among participation rate, barrier level, index volatility and correlation.

This paper derives conversion formulas from yearly-based absolute rates of decrements to monthly-based rates of decrement due to cause J under fractional age distributions. Next, it suggests conversion formulas from monthly-based absolute rates of decrements to monthly-based rates of decrement due to cause j under fractional age distributions. In addition, it applies the conversion formulas including a dynamic lapse rate model to variable annuities. Some numerical examples are discussed.

This study analyzes the conditions of merchandises from the popular domestic and foreign. In this study, 845 merchandises of 18 popular singers in Korea and 705 merchandises of 20 popular foreign singers are selected. The results of this study are as follows. First, the highest order of merchandise categories among Korean singers are stationeries and toys, followed by fashion accessories, clothes and interior decoration products. For the foreign singers, the highest order of merchandise categories are clothes, followed by fashion accessories, stationeries and toys, and interior decoration products. Second, the most common characteristics of graphic images on the merchandises from Korean singers are characters and expressions of person and body followed by logos, symbols, and gestures of body. Among the foreign singers, the most common characteristics of graphic images are logos, symbols, and gestures of body followed by logos, symbols. Third, by comparing the price ranges between the Korean and foreign merchandises, it is found that foreign singers' merchandises have a more diverse price range than local ones. The highest ordered price ranges among Korean singers are less than 10,000 won, followed by 10,000~20,000 won and 20,000~30,000 won. Among the foreign singers, the highest ordered price ranges are 20,000~30,000 won, followed by 20,000~30,000 won, and 30,000~40,000 won, and less than 10,000 won.

One of the most enduring concepts in the history of marketing thought relates to the classification of consumer goods. The product classification theory first proposed by Copeland(1923) has, with little modification, survived to the present day, and continues to be endorsed by the American Marketing Association and other related institutions some 80 years after it was first published. In truth, Copeland's classification is now outdated and bears little, if any, relevance to modern product advertising, retailing and consumption. In particular, it can not accommodate the fact that, in modern societies, consumer preoccupations with style, personal identity and status have meant that the social characteristics of goods, heavily promoted by brand managers who understand their markets, are key determinants of consumer choice and buyer behavior. In this respect, the author attempted to explore the reasons why product classification theory has been unresponsive to changes in market conditions over so many years and argue that its failure to embrace the many social influences on consumption and on consumer behavior is now its most serious weakness. And also, the author proposed the new categorization system of goods, based on the several existing literatures.
