  • The current distribution structure in Korea film industry is in the multiplex chain. As a result, most small or medium-sized theaters have been excluded from the market, and all the multiplex chain have gradually been formed into the vertical integration structure. The strike by multiplex theaters in Chuncheon who did not screen for one month led to the problem of the vertical integration, which resulted in many effects. Particularly, it caused considerable effect on the cultural desire and instigated movie-goers to turn to illegal content. This study surveys the process in which Korean multiplex theaters in vertical integration structure took over the Korean film market, and consequently, small theaters collapsed, and the theaters in vertical integration structure kick out small theaters in horizontal integration structure, and conducts a survey on the effect of the one-month strike by Chuncheon CGV from September 27 to October 30, 2008 in Chuncheon where said processes had completed so as to determine the effect of and impact of the problem of the vertical integration, monopoly structure. When major consumers of the film industry, i.e., people in their 20s, see their access to newly released films limited due to closing of multiplex theaters, they feel the impulse to access illegal contents. If they miss viewing the newly released films, they prefer to view illegal contents or films on recording media rather than visiting theaters showing those films. They are also influenced by timing of film release. Specifically, methods of illegal access to newly released films, permanent accessibility to them via recording media, and timing of film release influence their viewing patterns.

  • The ground fault is occupying 70% among the total number of faults in ungrounded distribution power system. When the ground fault occurs in ungrounded system, the fault current is so small that it is hard to detect. But fault handling is very important because to continue power supply during fault conditions may cause the fault spreading and the distribution device in trouble. This paper presents the fault line detection method by using GPT signal detecting zero sequence voltage, and the fault section detection method by detecting whether GPT signal is disappeared or not during shifting normally open switch, which is connecting switch between distribution lines with open state in order to restore the outage area under emergency situation, and during isolating each section one by one which belongs to the fault line. This method is efficient because there is no whole power interruption during the fault section detection, and it is possible to perform both the fault section detection and the service restoration for the outage area at the same time, and it can apply to various distribution system configuration. Program for the fault restoration was developed applying proposed method, and it has been validated by applying to the pilot project of distribution automation system in Vietnam which has the ungrounded distribution system.

  • Sporulation in the fission yeast Schizosaccharomyces pombe has been regarded as an important model of cellular development and differentiation. S. pombe cells proliferate by mitosis and binary fission on growth medium. Deprivation of nutrients especially nitrogen sources, causes the cessation of mitosis and initiates sexual reproduction by matting between two sexually compatible cell types. Meiosis is then followed in a diploid cell in the absence of nitrogen source. DNA fragment complemented with the mutations of sporulation gene was isolated from the S. pombe gene library constructed in the vector, pDB 248' and designated as pDB(spo5)1. We futher analyzed six recombinant plasmids, pDB(spo5)2, pDB(spo5)3, pDB(spo5)4, pDB(spo5)5, pDB (spo5)6, pDB(spo5)7 and found each of these plasmids is able to rescue the spo5-2, spo5-3, spo5-4, spo5-5, spo5-6, spo5-7 mutations, respectively. Mapping of the integrated plasmid into the homologous site of the S. pombe chromosomes demonstrated that pDB(spo5)1, and pDB(spu5)Rl contained the spo5 gene. Transcripts of spo5 gene were analyzed by Northern hybridization. Two transcripts of 3.2 kb and 2.5kb were detected with 5kb Hind Ⅲ fragment containing a part of the spo5 gene as a probe. The small mRNA(2.5kb) appeared only when a wild-type strain was cultured in the absence of nitrogen source in which condition the large mRNA (3.2kb) was produced constitutively. Appearance of a 2.5kb spo5-mRNA depends upon the function of the meil, mei2 and mei3 genes.
