Consumers exposed to aesthetic brands can not only experience sensory pleasure but also lead to strong customer loyalty. Furthermore, aesthetic brands can expect to lead to the overall experience of the brand. They include the brand's sensory, emotional, behavioral and intellectual experience. Since aesthetic brands related to the sensory representation of customers, consumers exposed to aesthetic brands can expect to have a meaningful impact on the overall experience of the brand. The study will select aesthetic brands that distributed in Korea and then compare the aesthetic characteristics of each brand. It also seeks to verify the brand attractiveness, consistency, prominence and influence of brand motifs on the brand's sensual, emotional, behavioral and intellectual experience. To verify the influence between variables proposed in this study, we would like to conduct a multiple regression analysis. SAS 9.4 used to verify the hypotheses proposed in this study. Cronbach's α measure to verify reliability of each measurement item. In particular, brand attractiveness and brand motif can verify empirically to confirm that they play an important role in inducing brand experience.

본 논문에서는 program-verify-read 모드를 갖는 고신뢰성 24bit differential paired eFuse OTP 메모리를 설계하였다. 제안된 program-verify-read 모드에서는 프로그램된 eFuse 저항의 변동을 고려하여 가변 풀-업 부하(variable pull-up load)를 갖는 센싱 마진 테스트 기능을 수행하는 동시에 프로그램 데이터와 read 데이터를 비교하여 PFb(pass fail bar) 핀으로 비교 결과를 출력한다. 그리고 모의실험 결과 program-verify-read 모드에서 24-비트 differential paired eFuse OTP와 24-비트 듀얼 포트 eFuse OTP IP의 센싱 저항은 각각 $4k{\Omega}$과 $50k{\Omega}$으로 differential paired eFuse OTP의 센싱 저항이 작게 나왔다.

Purpose - The objective of this study is to verify whether there are differences between Korean and Chinese consumers in the importance of the attributes such as shopping value and loyalty in social commerce. With the purpose of finding out these differences, the following questions are set up as research questions. First, will there be a difference between Korea and China in the importance of attributes of social commerce? Second, will there be a difference between Korean and Chinese consumers in shopping value? Third, will there be a difference between Korean and Chinese consumers in their loyalty? Research design, data, and methodology - The researchers collected data through self-administered questionnaires from Korean and Chinese consumers who had used social commerce within the past six months before answering the questionnaire. First, for social commerce users in Korea, comprising male and female university students in Chungcheong, a questionnaire was circulated. For social commerce users in China, university students within Beijing were surveyed. Responses to 336 questionnaires were used, excluding those with no answers or unreliable answers. Data coding and data cleaning were used. SPSS 18.0 was used. First, exploratory factor analysis is done to verify the validity of testing tools, and Cronbach's α coefficient is used to verify credibility. For factor analysis, the Varimax method is used. To verify the internal consistency reliability of each factor, the Cronbach's α coefficient is used to verify the credibility. Second, a T-test is done to verify differences between Korean and Chinese consumers for the importance of attributes. Third, ANOVA (Analysis of variance) is done to verify differences between Korean and Chinese consumers in shopping value and loyalty. Results - When Korean and Chinese consumers use social commerce, first, the importance of the attributes of social commerce is affected by four factors; playfulness and economic factors are more important to Korean consumers than Chinese consumers. As for informativeness factors, including product information and quality, and buyer comments, there was no confirmed difference between Korean and Chinese consumers. The convenience factor is more important to Chinese consumers than Korean consumers. Second, the factors affecting shopping value for Korean and Chinese consumers were hedonic shopping value and rational shopping value. To see the difference between Korean and Chinese consumers in shopping value factors, a t-test is conducted. As a result, in the rational shopping value factors of social commerce, Korean consumers scored higher than did Chinese consumers. These results were verified to be meaningful through statistics. In the hedonic shopping value factor of social commerce, Korean consumers scored higher than Chinese consumers. These results showed a significant difference. Third, loyalty in social commerce is higher for Chinese consumers than for Korean consumers. However, there is no difference in loyalty depending on sex. Conclusions - These results will hopefully be valuable and used in the future by Korean companies that wish to enter the Chinese social commerce market.

Since a long time ago, many railway engineers analyze and discuss the interface between the sub-system of railway, such as a wheel/rail interface, pantograph/catenary interface etc. The verifying of the system interface could help to achive the optimized performance and safety of the railway system considering that the railway system is constructed by various engineerings, such as civil, mechanical, electrical, etc. A rolling stock with distributed drive system, which will be developed by HEMU-400x project, is capable of running on high speed line and conventional line in Korea. To verify the performance of rolling stock, test run will be done with revenue service line. And the test items of the system interface have to be selected to verify a functional compatibility and physical force between rolling stock and infrastructure. In this paper, the authors will indicates the test items to verify system interface. To achive the conclusion, the authors analyze a specification of the development train and the design value of Seoul-Busan high speed line, which will be used for testing of the development train, and also, study the various case of high speed train commissioning.

최근의 소프트웨어 개발에서는 리팩토링이 활발하게 이용되고 있다. 리팩토링에 대한 관심이 높아지면서 요소 리팩토링을 정의해서 이들의 조립을 통해 더 큰 종류의 복합 리팩토링을 처리하려는 연구들이 많이 진행되고 있다. 복합 리팩토링은 조합된 요소 리팩토링의 순서대로 처리되기 때문에 프로그램에 실제 적용하기에 앞서 적용 가능성을 판단하는 것이 중요하다. 기존 연구들에서는 요소 리팩토링들의 선 후행조건들로부터 복합 리팩토링에 대한 선행조건을 계산하여 적용 가능성을 판단하고 있다. 이것은 선행조건이 정의되어 있는 복합 리팩토링만 판별할 수 있으며 선행조건이 정의되어 있지 않은 복합 리팩토링에 대해서는 적용 가능성을 판단할 수 없는 문제점이 있다. 본 연구에서는 복합 리팩토링의 명세를 추가로 정의 하지 않고 요소 리팩토링만으로 조립 가능 여부를 판단하고자 한다. 이를 위해 요소 리 팩토링을 명세하는 방법과 조립성 검사 방법을 제안한다. 이를 기반으로 프로토타입 도구를 개발해 보고, 적용사례를 통해 선행조건이 명세되어 있지 않은 복합 리팩토링들의 조립성 검사를 확인해봄으로써 본 연구의 효용성을 검토해본다.

본 논문에서는 BCD 공정 기반으로 PMIC용 고신뢰성 24비트 듀얼 포트(dual port) eFuse OTP 메모리를 설계하였다. 제안된 dynamic pseudo NMOS 로직회로를 이용한 프로그램 데이터 비교회로는 program-verify-read 모드에서 프로그램 데이터와 read 데이터를 비교하여 PFb(pass fail bar) 핀으로 비교 결과를 출력한다. 그래서 한 개의 PFb 핀만 테스트하므로 eFuse OTP 메모리가 정상적으로 프로그램 되었는지를 확인할 수 있다. 그리고 program-verify-read 모드를 이용하여 프로그램된 eFuse 저항의 변동을 고려한 가변 풀-업 부하(variable pull-up load)를 갖는 센싱 마진 테스트 회로를 설계하였다. Magnachip $0.35{\mu}m$ BCD 공정을 이용하여 설계된 24비트 eFuse OTP 메모리의 레이아웃 면적은 $289.9{\mu}m{\times}163.65{\mu}m$($=0.0475mm^2$)이다.

Korea Electric Power Research Institute in charge of the power IT project "Development of Prototype for Advanced Substation Automation System based on the Digital Control Technology", is performing the verification of performance of the substation automation system. In order to verify a system based BUS protection IED, the standardized document and procedures are required. But there is nothing to describe systematically how to verify IEC 61850 based IED in the system environment except an individual IED testing way and report. This paper presents the substation automation system based ways and procedures to verify the IED using UML(Unified Modelling Language).
