Recently, after Wide Area Outage of the North-Eastern United States occurred, many countries started to be concerned about WAMS (Wide Area Monitoring System), and Korean power system also experienced Wide Area outage according to typhoon Mae-Mi, and Haenam-Jeju HVDC line fault. Since it is too difficult to detect a symptom based on SCADA or EMS, a defense system of electric power infrastructure has required. In this research, the designed and developed system processes the time synchronized real time power system information based on GPS and shows the 2D/3D monitoring viewer using the phasor data and the results of three algorithms.

As entering in the time of high oil price, seriousness of an energy is on the rise and the importance of energy is growing. Especially, building energy occupying 24% of total demand of energy is expected to be possible to reduce energy demand more than other section. To reduce the building energy consumption, this study analyzes function and thermal performance of Super window by heat experimental apparatus. Super window is a 2-track low-e glazing window for high insulation efficiency. By applying the results of this experiment to building energy efficiency rating tool, this study compares energy efficiency rates depending on a region.-Jeju, South, Central. And it shows how much does Super window reduce Building energy consumption.

This study aims to provide the guidelines for planning and operating convention centers. A case study is utilized with the units of analysis, including Seoul COEX, Busan BEXCO, Daegu EXCO, Jeju ICCJEJU, Ilsan KINTEX, Gwangju KDJ Center, and Changwon CECO. The findings related to the operation of convention centers in Korea are summarized as follows: the interation of similar conventions; an increase in size; globalization; and specialization. With a view of marketing, this study concludes as follows: (1) initial categorization of target markets is needed due mainly to the founding purposes and the site characteristics of the convention centers in question while utilizing market segmentation strategies; (2) a specific target market should be selected and focused on it; and (3) the development strategy of an image and servicescape is demanded to devised in plan.

This paper describes the resource assessment of theoretical potential of ocean energy including tidal current energy, tidal range energy, wave energy and ocean thermal energy in Korea to provide reliable basis for feasible development plan of ocean energy. Because of different characteristics of each ocean energy resources, the resource assessment methods were established considering characteristics of each ocean energy resources. The coastal region of Korea has been divided into 10 regions. The results show that tidal current energy is abundant in Incheon-Gyunggi and Jeollanam-do and tidal range energy is abundant in Incheon-Gyunggi. And wave energy is abundant in Jeollanam-do, Jeju and Gyeongsangbuk-do and there is ocean thermal energy in Gangwon-do and Gyeongsangbuk-do.

In this paper, I have reviewed some of the Korean traditional architectural vocabularies that have to be reconsidered in terms of the problem of decode, the problem of meaning, the meaning of explain meaning, and the problem of form analysis. Especially, correct decode and interpretation of Uigwe's Korean ancient architecture borrowed character can correct old decode and interpretation. Furthermore, I confirmed that I could correct the Korean ancient architecture vocabulary that was expiscated wrongly. Especially borrowed characters corresponding to 머름[meoreum](paneling) have been known only far away 遠音[meoreum]. In addition, there were also 遠驗[meolheom] 亇乙軒[meolheon] 亇乙險[meolheom] 亇乙音[meoreom], and so on. Furthermore, in the process of decode these notations, it has become possible to assume that the original words of the modern language 머름[meoreum] also came from *멀험[meolheom]. On the other hand, there are many kinds of people like 付叱心[bussim] 夫叱心[bussim] 扶叱心[bussim] 富叱心[bussim] 富心[bussim]과 北叱心 [bussim] 北心[bussim]. You can also check the Korean ancient architecture vocabulary. However, corresponding words are difficult to find in modern Korean languages. However, in Jeju dialect, we can confirm the corresponding word. This word was used in the Joseon Dynasty, and confirmed that it is dead language today. As mentioned above, it is confirmed that there are many misconceptions about the decode and meaning of the architectural vocabulary made of borrowed character in existing architectural dictionaries, Korean dictionaries, and Korean ancient architecture related papers. Also, although the form is being confirmed, it has been confirmed that there are many things that need to be clarified, such as what the decode is, what the meaning is, and the origin I have also confirmed a number of things that need to be properly expomed in the original form, the original word. In the future, those who study Korean ancient architecture vocabulary and traditional architectural vocabulary should also be interested in these things and research it properly.

Co-infection with two virus species was previously reported in some cactus plants. Here, we showed that Notocactus leninghausii f. cristatus can be co-infected with six different viruses: cactus mild mottle virus (CMMoV)-Nl, cactus virus X (CVX)-Nl, pitaya virus X (PiVX)-Nl, rattail cactus necrosis-associated virus (RCNaV)-Nl, schlumbergera virus X (SchVX)-Nl, and zygocactus virus X (ZyVX)-Nl. The coat protein sequences of these viruses were compared with those of previously reported viruses. CMMoV-Nl, CVX-Nl, PiVX-Nl, RCNaV-Nl, SchVX-Nl, and ZyVX-Nl showed the greatest nucleotide sequence homology to CMMoV-Kr (99.8% identity, GenBank accession NC_011803), CVX-Jeju (77.5% identity, GenBank accession LC12841), PiVX-P37 (98.4% identity, GenBank accession NC_024458), RCNaV (99.4% identity, GenBank accession NC_016442), SchVX-K11 (95.7% identity, GenBank accession NC_011659), and ZyVX-B1 (97.9% identity, GenBank accession NC_006059), respectively. This study is the first report of co-infection with six virus species in N. leninghausii f. cristatus in South Korea.

Web-Based instruction system embodied according to traditional process until present. But, these method have inefficiency in system development and give trouble of operation and administration after development. Therefore, It need induction of component based development in Web-Based instruction system. In this research, I constructed score processing system by component composition. I embodied component by Java Beans and used C2 architecture at the composition method. In this result, I shown in application possibility of component based development in Web-Based instruction system as to construct whole score processing system through composition of each component.

Purpose: The purpose of this study is to analyze & suggest the variation of energy consumption consequent on thermal insulation performance strengthening from early 2000s when modernization of barracks began until the present targeting a large barracks. Method: To carry out this research, this study surveyed the standard of thermal insulation by year, which is being applied to a barracks by conducting literature search, and selected the standard model for a barracks. Also, this study analyzed energy consumption by year & region by performing simulation(ECO2)of the selected standard model. Result: As a result, it was analyzed that in case of a building which was completed in 2015, the energy consumption for air-conditioning & heating, lighting, and hot water supply over the year 2000 reduced by 11% on the average in central district, 10% on the average in southern district, and 17% on the average in Jeju, respectively.

Quantitative traits are mostly controlled by a large number of genes. Some of these genes tend to have a large effect on quantitative traits in cattle and are known as major genes primarily located at quantitative trait loci (QTL). The genetic merit of animals can be estimated by genomic selection, which uses genome-wide SNP panels and statistical methods that capture the effects of large numbers of SNPs simultaneously. In practice, the accuracy of genomic predictions will depend on the size and structure of reference and training population, the effective population size, the density of marker and the genetic architecture of the traits such as number of loci affecting the traits and distribution of their effects. In this review, we focus on the structure of Hanwoo reference and training population in terms of accuracy of genomic prediction and we then discuss of genetic architecture of intramuscular fat(IMF) and marbling score(MS) to estimate genomic breeding value in real small size of reference population.
