We investigated the frames represented in the news media coverage in Korean daily newspapers during dismissal procedure of the director-general of the public service broadcaster, KBS. We analyzed 470 newspaper stories in the period surrounding the dismissal. The use of news frames in newspapers depended on the disposition of outlets, conservative or progressive. Conservative newspapers, ChoSun and DongA, described the dismissal of the director -general with a generally favorable or supportive view, but progressive outlets, Hankyoreh and KyeongHyang, reported more and non-favorable for the issue. Our results showed that conservative newspapers more often used episodic and cause for dismissal frame in the presentation of news, whereas progressive more often used thematic and media independence frames. Main frames commonly used in the news are the cause for dismissal, conflict, media independence, and regime maintenance, respectively, which are formed by 9 minor news frames. Conservative newspapers concentered on the cause attribution; management responsibility, conflicts, and dismissal procedures, but progressive focused on media independence and dismissal procedures. All newspapers selectively quoted groups, institutions and actors to enhance their messages and frames. Finally, there was significant difference between stories in each newspapers and the court's ruling for the dismissal.

The primary focus of Korea's advertisement policy has been on the securing of stability in the market through building categorical entry barriers whenever a new broadcaster came into the market. But the recent contraction of the advertisement market is pressing the policy makers to lift the categorical barriers to create one large-enough market. This change in the policy and the market, in turn, is triggering heightened competition among drama producers to get advertisements, at times, even at the expense of cost efficiency. The market is supposed to search for its own equilibrium in principle. This means that players, who fall behind, should be left to die out and exit, and the patient policy to let the market function on its own should be institutionalized. Separately, the fee-based public broadcasters should be banned from running advertisements.

In an identity-based threshold broadcast encryption (IDTHBE) scheme, a broadcaster chooses a set of n recipients and a threshold value t, and the plaintext can be recovered only if at least t receivers cooperate. IDTHBE scheme is different from the standard threshold public key encryption schemes, where the set of receivers and the threshold value are decided from the beginning. This kind of scheme has wide applications in ad hoc networks. Previously proposed IDTHBE schemes have ciphertexts which contain at least n elements. In addition, the security of theses schemes relies on the random oracles. In this paper, we introduce two new constructions of IDTHBE for ad hoc networks. Our first scheme achieves S-size private keys while the modified scheme achieves constant size private keys. Both schemes achieve approximately (n-t)-size ciphertexts. Furthermore, we also show that they are provablesecurity under the decision bilinear Diffie-Hellman Exponent (BDHE) assumption in the standard model.

In Korea's drama industry, a production factor has several prices, not one, bucking the general economic theory. The price changes depending upon the broadcaster, the producer, and even the genre. The price gets determined by such factors as the scarcity, the substitutability, the overall budget size, and so on. For star actors, the price stands for their popularity and ego, which makes them strive so desperately for a higher pay than competitors. The rise of the production factor price has outpaced that of the production budget, to cause undesirable structural problems. It is deemed that the running guarantee could be a way to rationalize the pricing system for production factors in Korea.

The starting point of this study is an examination of the vital role of terrestrial broadcasting in Korean society, where ethnic minorities have increasingly become visible. Korean terrestrial broadcasters' mandate emphasises the broadcaster's responsibility to represent and reflect the range of public opinion and experiences beyond class, age, ethnicity and ideological orientation. The main purpose of this study is to visually examine the means through which terrestrial broadcasting generates discourses of We-ness and Otherness at times of change in the Korean society. The study focuses on prime-time broadcasting news programmes' visual representations of migrants and ethnic minorities.

Fertilizer impaction mechanism was simulated using a commercial program RecurDyn$^{(R)}$ a dynamic program that could handle contact problems. Even if there had been numerous papers on modeling of fertilizer applicator, the performance predictions were not satisfactory due to simplification in modeling. The most significant simplification was assumption of fertilizer particles as a solid particle. The assumption would eliminate rotation of fertilizer particles during the impaction mechanism. However, impaction of rotating body would be different from that of a solid particle. This paper introduced how the impaction was modeled using RecurDyn$^{(R)}$. In order to simulate, restitution coefficient and contact time was measured. A stiffness coefficient and a damping coefficient of a fertilizer was theoretically estimated using the measured data. Validity of the simulation result was not proved yet, but judged to be promising.ged to be promising.ing.

The right to the spectrum frequency and orbit is required for the broadcasting by satellite, whether the broadcaster might be given any license or authorization for the broadcasting. The reason is that the ITU Convention and Radio Regulation provide very specific and detailed rules regarding the utilization of the frequency spectrum and orbit. Outstanding issue arises as to the implementation process of the rules of international character. Domestic implementation of the Radio Regulation, in the way of letter to letter should be discouraged when the competitiveness of domestic industry vis-a-vis foreign competitor is taken into account.

The purpose of this study is to know about the interference on FM Radio channel from DRM+ signal. In Korea, a data service channel, named DARC is operated by a major FM radio broadcaster which has national wide service area. Therefore, an analysis of the interference on FM radio channel with DARC data channel from DRM+, most recently developed digital radio system. Technical parameters of FM radio with DARC data channel and DRM+ system are considered for this simulation. To maintain without no interference from DRM+, FM radio channel with DARC data channel should have the power level difference over 14.7dB at 150KHz frequency distance.

The purpose of this study is to know about the interference on FM Radio channel from HD Radio signal. In Korea, a data service channel, named DARC is operated by a major FM radio broadcaster which has national wide service area. Therefore, an analysis of the interference on FM radio channel with DARC data channel from HD Radio, most recently developed digital radio system. Technical parameters of FM radio with DARC data channel and HD Radio system are considered for this simulation. As results some interference generated because of HD Radio signal according to its signal allocation and service mode of HD Radio.

This research deals with meanings and issues of 'broadcasting area' in which trans-regional broadcasting media such as satellite broadcasting and webcasting provoked. The issues around broadcasting area have raised the examination of fundamental broadcasting philosophy in Korea, i.e. establishment of broadcasting area intends to foster new media development? or protect local culture and local journalism? After assessing current criticisms around the broadcasting area, this study particularly addresses re-transmission outside the broadcasting area, satellite broadcaster's re-transmission of terrestrial channels, and widening of broadcasting area. This research argues that broadcasting area has lost its raison-etre due to the advent of new communication technology, even though it was maintained to protect regional broadcasting stations. Therefore it argues that now is the right time to change the broadcasting area in the digital media era. This approach could strengthen the competitiveness of regional broadcasting stations and solve the rows surrounding broadcasting areas.
