In this paper we propose a knowledge management plan for the home shopping industry. Among whole business areas we focus on the business area of the Broadcasting Management and Operation(BM&O). We analyze problems embedded in the business area BM&O, design a knowledge management model (including business processes, information systems, organizations, regulations, and culture) for overcoming the problems, and finally make an action plan for implementing the model into the home shopping company. We expect the proposed model and action plan will be used as an useful reference model for maintaining one's competitive power in the home shopping markets.

Fractional Brwonian motion(fBm) has properties of behaving tails and exhibiting long memory while remaining Gaussian. In particular, it is well known that interest rates show some long memories and non-Markovian. We present no aribitrage condition for HJM model under the multi-factor fBm reflecting the long range dependence in the interest rate model.

부가서비스는 공급자가 소비자에게 제공하는 본질적인 재화 또는 서비스에 추가하여 부수적으로 제공되는 서비스라는 사전적 의미를 갖고 있다. 최근에는 IT 기술이 발전함에 따라, 웹을 기반으로 한 다양한 부가서비스가 각 산업에서 등장하였으며, 때로는 기본적인 서비스처럼 여겨지기도 할 만큼 성장하고 있다. 전력산업에서도 이러한 시대적 요구와 경쟁력 강화를 위한 수단으로 부가서비스가 도입되고 있다. 초기에는 주로 이메일 청구서 형태의 단순한 서비스였으나, 현재는 다양한 전력 인프라와 데이터를 이용한 전력부가서비스가 시도되고 있다. 국내에도 전력부가서비스 개념이 도입되어, 초기에는 전력부가서비스의 필요성과 이에 대한 인식이 부족하여 제한적인 분야에서만 개발되어왔다. 그러나 최근들어 공급자는 고객을 위한 부가서비스의 중요성을 인식하게 되고, 수용가 또한 이에 대한 높은 관심을 보임에 따라, 점차 다양한 분야로 확대되는 경향을 보이고 있다. 본 논문에서는 이와 같은 시장의 변화를 고려하여, 국내의 전력산업 환경에 적합한 부가서비스 BM을 개발하되, 성공적인 전력부가서비스로 구축하기 위해 수용가의 선호도와 요구사항을 조사하고 이를 충분히 반영한 전력부가서비스 BM(Business Model) 개발 및 시스템 구축방안에 대하여 소개하고자 한다.

Empirical findings on interet rate dynamics imply that short rates show some long memories and non-Markovin. It is well-known that fractional Brownian motion(fBm) is a proper candidate for modelling this empirical phenomena. fBm, however, is not a semimartingale process. For this reason, it is very hard to apply such processes for asset price modelling. With some modifications, this paper investigate the fBm interest rate theory, and obtain a pure discount bond price and Greeks.

The most presentative case would be functional evolution of webtoon as a contents business model, which has taken a initiating role in both innovated strategic experiments and outcomes. Most of all, There are the launch of PPS(Page Profit Sharing) sevice in NAVER webtoon, the paid service model implementation in KAKAOpage and potential business as an exclusive application in Lezhin entertainment This study to analyze these phenomina and results can figure out how the business model in the webtoon platform is developed in various fields diversely and what makes this model evolved and extended. Especially, the diversification of the webtoon platform has been received attention since it pursued the grouped spin off through horizontal convergence and transformational expansion among similar platforms, and also this shows that which factors enhance these phenomina to be controled and expanded. On the basis of the result of this study, we try to find the way to connect business vision of the domestic webtoon platform with affiliated business. Furthermore, it proposes the interrelationship between this and the business strategy for overseas in the globalized platform.

This study proposes that the cultural corporation can be more profitable by adopting the 'Buy-One Give-One' Business Model (BOGO BM) under certain conditions. Specifically, the conditions are that 1) consumers' utility for donating is high enough and 2) the production cost is low enough due to economies of scale or process innovation from employee's intrinsic motivation. We adopt a mathematical model where the demand function is a simple linear function and two companies compete with each other by choosing their quantity of output (the Cournot model). Specifically, we investigate the profitability of the BOGO BM in four situations: 1) a monopolist enjoying reduced cost due to process innovation from employee's intrinsic motivation, 2) a monopolist enjoying reduced cost due to economies of scale, 3) the duopoly with BOGO BM and a general company, 4) the duopoly with two BOGO BM companies. In each situation, BOGO BM can be more profitable than other general companies can under certain conditions.

This paper develop self pre-checkup lists for the validity of business model as web business starters can utilize to open business. In particular, self pre-checkup lists invented by Dr. Bruce Merrifield, is reapplied and modified in appropriate to internet shopping mall business. This paper complete many literature reviews to identify appropriate factors of evaluation such as about the characters of internet business, business validity testing theory for internet business model, pros and cons of e-business and startup ventures, factor analysis of technology valuation, and pros and cons for internet shopping mall. This paper define six different factors; scale of sales, the growth rate of market, competitiveness, risk portfolio, industry upside down, and social conditions, as the factors of evaluating the business attractiveness. Meanwhile, it define characters of CEO, content's power, mutual inclusion, commerce, fulfillment, marketing power as the factors of business appropriateness. This paper also conducts several case studies; company I, D, G of applying the former model. This paper sort out internet business model in imaginations by utilizing self pre-checkup lists of business evaluation. Also, the outcomes of evaluation is expected to provide meaningful future business implications.

We present formulas for two types of cap pricing under fBm-HJM model reflecting the empirical long range dependence in the interest rate model. In particular, we propose a new approach to pricing the cap with the default risk.

In this paper, the fBm interest rate theory is investigated by using Wick integral. The well-known Affine, Quadratic and HJM are derived from fBm framework, respectively. We obtain new theoretical results, and zero coupon bond pricing formula from newly obtained probability measure.
