  • The objective of this study is to understand the relationship between type of advertising and brand attachment. We divide advertising type into loss and gain frame and examine the effect on brand attachment, The effect of scarcity advertising on brand attachment and the effects of interaction effects on brand attachment were examined. The results showed that the effect of the loss and gain frame on brand attachment was not statistically significant. It also showed that scarcity was not emphasized or emphasized or had no effect on brand attachment. That is, the more emphasis on gain in advertising frame and the less pressure on scarcity, the more effective ad type for brand attachment.

  • In this paper, we propose a gait type classification method based on pressure sensor which reflects various terrain and velocity variations. In order to obtain stable gait classification performance, we divide the whole gait data into several steps by detecting the swing phase, and normalize each step. Then, we extract robust features for both topographic variation and speed variation by using the Null-LDA(Null-Space Linear Discriminant Analysis) method. The experimental results show that the proposed method gives a good performance of gait type classification even though there is a change in the gait velocity and the terrain.

  • In a section of AC electric railway, a phase between the sections is different although voltage levels supplied from substations are the same. Therefore, section insulators have been installed to electrically divide between the sections. Two differenet types of section insulator, namely an overlap type and insulator type, are used. In Korean high-speed lines, overlap type section insulator has been adopted. And, insulator type is used in conventional line. The overlap type has the advantage of having no speed limit, but has the disadvantage of requiring long section length. However, the insulator type has the advantage of section length, but also has the disadvantage of having speed limit. In Korean conventional line, an insulator type one relies on the import and there is some problem with wear. In this study, we developed the insulator type section insulator which adopts Teflon tube insulation material. The Teflon material has advantage of the excellent electrical characteristics and wear-resistance characteristics for a longer expected life than that made of existing FRP. In order to compare wear characteristics between the materials, wear tests with reciprocal wear tester are performed. And dynamic behavior tests between the insulators and pantograph are also performed for showing its better dynamic characteristics.

  • About two thirds of the naturally occurring antibiotics have been discovered from actinomycetes. Therefore, the probability of discovering further new antibiotics from actinomycetes is declining as many known metabolites are isolated repeatedly. However, various efforts leave been made in order to enhance the probability of discovering novel compounds. In the present study, we have developed new screening strategies based on the antibiotic biosynthetic pathway, and the genetic information, utilizing polymerase chain reaction. We have selected macrolide type polyketides. In order to divide the ansamycin group antibotic of macrolide type polyketides, we have selected 3-amino-5-hydroxybenzoic acid (AHBA) moiety which contains a biosynthetically unique structural element in the group as a target molecules. Oligonucleotide primers were designed to amplify DNA fragments of macrolide type polyketide synthase and AHBA synthase genes from fourteen actinomycetes species. This method was successfully applied to all three of the known macrolide type polyketide produccing actinomycetes tested. In addition, it also identified the presence of potential macrolide type polyketide producing genes from seven actinomycetes that were known to produce none of macrolide type polyketides, and AHBA biosynthetic genes in one actinomycetes. This technique is potentially useful for the screening of new antibiotices and cloning of their biosynthetic genes.

  • This paper is to cluster the AMR (Automatic Meter Reading) data. The load survey system has been applied to record the power consumption of sampling the contract assortment in KEPRI AMR. The effect of the contract assortment change to the customer power consumption is determined by executing the clustering on the load survey results. We can supply the power to customer according to usage to the analysis cluster. The Korea a class of the electricity supply type is less than other country. Because of the Korea electricity markets exists one electricity provider. Need to further divide of electricity supply type for more efficient supply. We are found pattern that is different from supplied type to customer. Out experiment use the Clementine which data mining tools.

  • Local heating transportation pipe has sensor and return lines to detect water-leakage. There are impulse and resistance comparison measurement types for a water-leakage detection. The impulse type shows large detection error within a measurement range. Since the resistance comparison type can find a comparative accurate single water-leakage point in the measurement range of heating pipe, it has been used to detect water-leakages these days. However if the multi water-leakages are happened in the measurement range of transportation pipe. the resistance comparison type shows a detection error point by the parallel resistance between a detection sensor line and ground. But the detection error will be minimized by the divided transportation pipe loops. In this research, it suggests the design of remote controlled detection system which can divide a large pipe loop and a possible single water-leakage measurement process in each divided loops.

  • 본 연구에서는 사회경제적 특성에 따라 인터넷 접근, 인터넷 이용 정도 및 인터넷 서비스 이용 상의 디지털 격차가 어떻게 달라지는가를 체계적으로 규명하고자 하였다. 이를 위해 본 연구에서는 한국인터넷진흥원의 인터넷이용자실태조사 데이터를 이용하여 사회경제적 특성에 따른 인터넷 접근과 인터넷 이용(양적 이용 정도, 인터넷 서비스 이용)의 디지털 격차를 로지스틱 회귀분석방법으로 검증하였다. 분석결과, 인터넷 접속(가정에서의 인터넷 접속, 초고속 인터넷 접속)과 인터넷 이용정도(적극적 이용, 정기적 이용, 비정기적 이용)는 연령, 성별, 교육수준, 고용상태, 소득수준, 인터넷 접속 유형 등에 따라 디지털 격차가 존재하는 것으로 나타났다. 인터넷 서비스 이용(정보 활용, 커뮤니케이션 및 커뮤니티, 전자상거래, 인터넷 뱅킹)의 경우 고학력자 및 고소득층이며, 학생이고 젊은 연령층일수록 인터넷 서비스를 많이 활용하는 것으로 나타나 사회경제적 특성에 따른 인터넷 서비스 활용 격차가 존재하는 것으로 검증되었다.
