The green premium is the most important feature of Korea's RE100 system. Green premium has three characteristics. The first, the cost of implementation is lower than that of other means of implementation. The second, it is linked with the RPS system to keep the means of implementing the green premium low. Third, the funds raised by the green premium are used to supply renewable energy to compensate for the additionality that the green premium does not have. When the entire industrial sector's electricity consumption is converted to renewable energy, the implementation cost of the green premium is estimated to be 3,377.4 billion won, and the REC purchase is estimated to incur the implementation cost of 6,576.4 billion won, which is 3.5 trillion more than the green premium. It was analyzed that an additional implementation cost of KRW 100 million would occur. In addition, in the case of solar PPA, it was analyzed that additional implementation costs of KRW 13,375.7 billion to KRW 16,162.3 billion were incurred. It was estimated that the renewable energy that could be supplied to the green premium would at least be sufficient for companies exporting to the US and EU. In addition, it was analyzed that when the fund created as a green premium is used for renewable energy supply, about 30.7% of the renewable energy supply through PPA can be supplied. However, as ESG is emphasized, green premium can be criticized by green washing because there is no additionality. There is also a limit to responding to the EU's CBAM. Therefore, companies can use the green premium depending on the situation, but it is more advantageous to use PPA, etc. The government needs to sufficiently maintain the supply of renewable energy using the fund to maintain the green premium.

As most of firms related with P2P services change their free services into fee-charging services, the problems of intellectual property rights are solved to satisfactory extent. Accordingly, P2P systems become more popular with the general public. In this respect, it is thought to be very important to research on the critical factors affecting usage of P2P systems. Although it is strongly expected that the characteristics of users activities in virtual communities affect the intention to re-use P2P systems, relatively few attention have been paid to this question. Therefore, this paper is to present empirical evidence to explain how the characteristics of users activities in virtual communities affect re-use intention of P2P services. The theoretical contribution of this study is that the characteristics of users activities in virtual communities is theoretically derived from the comprehensive literature review and the logical reasoning, and that the research model of the relationship between the users activities' characteristics in virtual community and the re-use intention of P2P services is proposed and empirically validated, which is expected to expand explaining power of the TAM(Technological Acceptance Model). Also, the practical implication is to provide the guideline to support the successful strategic planning for development and.operation of P2P services through the virtual communities.

The adverse events which do not appear in the approval process tend to occur more frequently at the early stage of the use. Therefore new drugs, drugs with different active substances or routes of administration, or drugs with explicitly different efficacy added are particularly chosen for re-examination, and go through a study, which is conducted on 600 to 3,000 subjects over 4 to 6 years. Since the re-examination system was implemented in January 1995, 880 drug products have been designated as the subject of re-examination and among them 194 drugs have been completed their re-examination as of until March 2005. Post Marketing Surveillance to insure drug safety should be correlated with re-examination of new drug, re-evaluation of drug, and adverse event monitoring system. And the first labeling change should reflect all information collected for a defined period of time after the marketing authorization is granted. Furthermore centralized management through spontaneous reporting system of adverse event for whole period of time would be the most desirable type of system.

Epoxy-coated re-bar was partly used to the structures and put to practical use, but were not economical and appeared to have defects such as the diminishing of long term bond strength between concrete. The study of polymer cement slurry coated re-bar was started in order to complement the defect of epoxy coated re-bar, and ever since the basic properties appeared to be excellent. But, study of bond properties embedded in concrete specimens was insufficient until now. This study attempts to examine the possibility of improving the bond strength of polymer cement slurry coated re-bar between concrete specimens in accordance with ACI Code and KS Code through pull-out test of 150mm$\times$150mm$\times$150mm substrates with polymer cement slurry coated re-bar having polymer cement ratios of 50%, 75% and 100%, coating thickness 250${\mu}{\textrm}{m}$, 450 ${\mu}{\textrm}{m}$ and with curing ages of 3, 7 and 28 days. High strength concrete was designed having a compressive strength of 500kgf/cm2 as specified. Practical bond length ranges of 55 and 85mm were applied to each of specimen. The bond strength of polymer cement slurry coated re-bar using St/BA-1 and St/BA-2 was compared to that of plain re-bar. The results of this study showed that the bond strength of 55mm bond length was much higher than that of 85mm bond length.

In this study, the characteristics of heating performance of a high-performance air-cooled heat pump with vapor-injection(VI) cycle using re-heater was investigated experimentally. Devices used in the experiment is consist of a VI compressor, condenser, oil separator, refrigerant (economizer outlet refrigerant) re-heater, economizer, evaporator. And R410A was used as a working fluid. The experiment was conducted with two cycles(cycles A and B) for investigating heating performance. In case of cycle B, heat exchange was conducted by re-heater between outlet refrigerant of compressor and suction refrigerant of the VI system(Fig.1, re-heater). But the re-heater was not used in case of cycle A. As a result of this experiment, discharge temperature of refrigerator in compressor was shown higher value, when the cycle B was conducted, because of the heat exchange between suction refrigerant of VI cycle and outlet refrigerant of compressor in the re-heater than cycle A that was not use re-heater. it means that liquid hammer and the decrement of heating performance can be decreased by using re-heater. Also, Heating coefficient of performance(COPh) was shown about 2.98 in Cycle B which was 4% higher than Cycle A and from these results, It was confirmed that the improvement of the heating performance of heat pump with VI cycle can be achieved by applying re-heater.

This study examined the image identity of the Celine fashion house, which went through a successful re-branding using its tradition and succession, a process that was heavily influenced by their new designer, Phoebe Philo. The purpose of this study is as follows: first, to encourage the use of the fashion house in a domestic fashion market. Second, to increase awareness about image identity. Third, to provide suggestions of maintaining sustainable brand by examining a fashion house, which does not follow fast-changing fashion trends but rather leads and creates fashion styles. The study extracted the characteristics of the Celine fashion house by analyzing data, which were collected from fashion literature, its designs, and its marketing. From the data, the study found ways that a brand could use to develop continually. Phoebe Philo re-branded the Celine by using minimalism to redesign its logo and create a new brand image. Her method included the use of diverse and vivid colors via color-blocking, a feature of modern minimalism. This is a modern minimalism, which differentiates itself from others with the elaborate tailoring and delicate detailing effectively. The modern minimalism like this has, caused the new mood beyond the flow of certain art trends and led the revolution, not the advent, of the minimalism in the 1990s. This study believes that the aspect of the fashion-house following and succeeding the tradition is not just in the fashion house. This study should be seen as a significant step forward at a time when we desperately need the continuation of the unique brand recognized as fashion house in the long-term domestically.
