For digital TV, the recommendation of u-health personalized service of semantic environment should be done after evaluating individual physical condition, illness and health condition. The existing recommendation method of u-health personalized service of semantic environment had low user satisfaction because its recommendation was dependent on ontology for analyzing significance. We propose the personalized service recommendation method based on Naive Bayesian Classifier for u-health service of semantic environment in digital TV. In accordance with the proposed method, the condition data is inferred by using ontology, and the transaction is saved. By applying naive bayesian classifier that uses preference information, the service is provided after inferring based on user preference information and transaction formed from ontology. The service inferred based on naive bayesian classifier shows higher precision and recall ratio of the contents recommendation rather than the existing method.

The purpose of this study is to find an efficient marketing strategy in terms of media channel communications using one specific case study. Results of previous studies have shown that consumers' exposure to TV, newspaper, radio and magazine related to description of corporate image tends to be influential for consumers' product image, which mainly consists of product preference, expertise, and credibility. It means that media strategy should be different, depending on what kinds of image they try to be purposive. In conclusion, we concluded that TV and radio should be the best vehicle for increasing consumers' positive preference rather than those of newspaper and magazine. Newspaper and magazine are also influential in terms of expertise, and newspaper and magazine should be better than TV and radio in terms of credibility. The results of this study should be similar to previous studies in that TV and radio should be more inducing interest, and print media should be more credible than TV and radio.

A dispute over price for retransmitting terrestrial channels between Terrestrial Television Systems and Cable TV System Operator(SO)s has been underway up to now since 2007 and expected to last unless there is a measure of extraordinary countermeasures. Thus, in this paper, we present a scheme for calculating the reasonable price on retransmitting terrestrial channels. Re-transmission price calculation scheme is presented in two ways. One is to calculate the price for the extent to which Terrestrial broadcasters and Cable broadcasters contribute, and the other is to calculate the price for terrestrial channels retransmitted by applying the method of Cable TV PP program fee basis. In addition, on profit-sharing scheme and criteria for program fee we present two ways of subscription, which are flat sum system and fixed rate system.

Study findings are as follows: As for the influence of TV home shopping household goods' price upon its sales, because TV home shopping business entities set in advance an efficiency unit-price per broadcast hour and carry out a sales strategy of reaching out the efficiency, they try to keep their sales with discounted price in the real sales setting of TV home shopping. But it is not an exclusive practice. General promotion became a common practice. The price of goods is the same with its life. Continuous discount events lower the reliability of goods and its supplier must bear the result. Overall sales after experiment increases by 13% and the sales efficiency also increases by 9%.

The purpose of the study was to analyze narrative structure and spoken contents of two TV documentaries televised in KBS 1TV 'Current Topics Ssam' to examine how child sexual abuse was represented on TV. As a result, the study could see that child sexual abuse attackers were stressed by a system to monitor and punish them and TV documentary took a neutral attitude between their human rights and pain of the victims. And it emphasizes 'abnormal' sides such as attackers' drinking or history of mental illness, and men's social authority individualizes a woman's damage into private pain by imposing a light punishment on child sexual abuse attackers and letting them not punished. Child sexual abuse victims treated to be a sexual object as a 'small, easy and weak' woman are represented as a lethargic human who is afraid of revenge and lives in pain. The representation of child sexual abuse through 'Current Topics Ssam' has its limit in the fact that it neglected understanding social context of child sexual abuse by forming an event-centered immediate and fragmentary narration and didn't play a right role in making an efficient and long-term plan considering actual conditions of Korean society and leading the people's participation.
