안경 산업은 현대사회의 복잡성에 따라 사용자가 매우 가파르게 증가하고 있는 실정이다. 기존 안경 산업은 주로 오프라인에서 사용자의 필요에 따라 사용하는 필요성에 의한 산업구조인 반면에, 최근의 안경 산업은 고객들의 선호도에 따라 다르게 착용함으로써 외적 미모를 위한 개성 연출을 위한 도구로서 활용도가 다양화되고 급증하고 있는 추세이다. 이에 본 연구에서는 젊은층 및 노년층의 구분없이 다양한 계층에서 활용도를 유도할 수 있도록 개인 맞춤형 안경산업의 온라인 사업에 초점을 둔 온라인 안경사이트 구축에 관한 연구이다. 이를 위해서 기존의 대표적인 안경 산업의 특징과 산업 서비스 분석을 통해 차별화된 전략을 제시하고자 한다. 본 연구를 통해 서비스 개발과 실용적인 접목이 이루어진다면 비즈니스 모델의 새로운 가치를 도모할 수 있을 것으로 기대된다.

Construction projects that should be under the construction supervision regulation were decreased in 2008 and new supervision projects in 2010 were significantly reduced by 60% comparing to the ones as of 2009. On the contrast, the volume of world construction projects including Middle·South Asia and Africa is forecasting to be increased by 46% in 2018. However, although the needs of oversea expansion of domestic construction supervision firms are appeared more and more, their preparations to the strategically important areas in the world are insufficient. Thus, this paper aims to suggest directions of strategics and plans for domestic construction supervision industry to expand the market to the world through questionnaire surveys and expert investigation.

ebXML (Electronic Business using extensible Markup language), sponsored by UN/CEFACT and OASIS, is a modular suite of specifications that enables enterprises of any size and in any geographical location to conduct business over the Internet. Using ebXML, companies now have a standard method to exchange business messages, conduct trading relationships, communicate data In common terms and define and resistor business processes. It is the mission of ebXML that provides an open XML-based infrastructure enabling the global use of electronic business information in an interoperable, secure and consistent manner by all parties for creating a single e1ectronic electronic market. This paper briefly overviews the concept of core component, context, assembly rule and context rule. Then, It designs by standard specifications of ebXML core component commonly used in an industry and among industries, and assembles business messages by using XML schema. Therefore, it suggests the mechanism which effectively exchanges business messages among the trading partners. This paper designs core component by using only three business messages of retail industry : orders, dispatch report, sales report.

The purpose of the present study is to build a model to determine the structure of long-term quasi-optimal rates of local and toll telephone services. The outline of this study is as follows : Telephone business, providing social goods, is capital-intensive industry which needs huge fixed cost to operate exchanges and telephone networks nationwide. The nature of above industry justifies the market structure of telephone business to be natural monopoly and makes a good reason for government's direct regulation, that is, price regulation. Three is a gap between the present rates and the quasi-optimal ones because some administrative processes intervene in rate making process before execution. On the above diagnostic basis, the present study made an empirical test for the optimality of present rates structure in connection with Ramsey-Boiteux model to maximize the sum of producer's and consumer's surplus and also the current study proposed a qusasi-optimal rates structure for better market performance. From the empirical analysis, we can deduce a policy recommendation the local price should be increased to 47% whereas toll price decreased to 24% in order to improve the net welfare worth of 32.6 billion won.

Even though red pepper is one of the most important agricultural products in Korean, the red pepper industry is decaying due to several reasons. In order to solve this problem, more specific studies are required. The purpose of this paper is to analyze the production and consumption sector of Korean red pepper market and to present the implications for the promotion of Korean red pepper industry. Survey analyses to producers and consumers were conducted for this research. The results of studies present a few findings: First, Korean consumers consume foreign red pepper products as well as domestic red pepper products, Second, more RPPC (Red Pepper Processing Complex) should be introduced, Third, WTP (Willingness To Pay) of consumers to red pepper products is different from WTP of producers, Forth, Consumers' requirements to promote the red pepper market is also different from producers' strategies.

Price control can restore efficiency in some cases, but an uncarefully designed policy fails to restore efficiency, yields side effects, or even exacerbates efficiency losses. This paper shows that the copyright royalty rule, which takes the greater of ad valorem royalties and perunit royalties, tends to fix the prices of final goods at a specific level. Such a rule weakens competition as it prevents prices from decreasing even when market conditions change, having negative effects on social welfare as well as consumer surplus. Counterfactual analyses using estimation results in the Korean online music service industry show that firms could have profitably reduced prices if the ad valorem rule had been applied instead, although they did not have an incentive to do so under the original combination rule.

In recent, the rapid convergence of telecommunication and broadcasting has been considered as one of the hot issues in the IT industry. This convergence will provide telecom operators with both opportunities and threatens. This is because that telecom operators can enter the broadcasting industry, whereas broadcasters will also have a chance to provide telecom services. This work aims to discuss the business strategy for telecom operators to provide a TV VOD service, one of the convergence services between telecommunication and broadcasting, through the high-speed internet which is so much served in Korea. It seems that this service will achieve two business goals, namely "to minimise an additional investment" and "to find out a new benefit source", by fully utilising a current high-speed internet infrastructure. Finally, this paper mainly contains the market overview of in telecom and broadcasting service, the definition of TV VOD service and the necessity for this service, a market forecasting and the provision strategy of major telecom operators, and key success factors and a benefit model.

The margin level in the futures market platys an important role in balancing the default probability with the investor's opportunity cost. In this paper, we investigate whether the movement of KOSPI200 futures daily prices can be modeled with the extreme value theory. Based on this investigation, we examine the validity of the margin level set by the extreme value theory. Moreover, we propose an expected profit-maximization model for securities companies. In this model, the extreme value theory is used for cost estimation, and a regression analysis is used for revenue calculation. Computational results are presented to compare the extreme value distribution with the empirical distribution of margin violation in KOSPI200 and to examine the suitability of the expected profit-maximization model.
