Cross-border online shopping is an example of non-mobile transnational consumption behavior that has become more popular over the last decade due to the development of technology and transportation. Based on the Theory of Reasoned Action(TRA), this study proposed and tested the hypothesized model that would explain the relationships among consumption beliefs, attitudes toward cross-border online shopping, subjective norms, and purchase intention. Consumption beliefs were measured by global consumption orientation, consumer orientation, and global brand beliefs. In addition, subjective norms included two types: online and offline norms. Descriptive statistics and path analysis were employed for the analysis of the dataset of 174 participants. As a result, the hypothesized model was generally supported. Consistent with the hypothesis, global consumption orientation and global brand beliefs were positively related to positive attitudes toward cross-border online shopping but negatively associated with consumer ethnocentrism. Offline subjective norms positively predicted both the attitudes and purchase intention whereas online subjective norms only predicted purchase intention. The results reflected that TRA was applicable to the intention of cross-border online shopping in a current on-line shopping context. We also discussed the practical applications and limitations of the study.

MPEG에서 진행 중인 MPEG Media Transport(MMT) 표준화는 IP기반 방송통신융합망에서 효과적인 멀티미디어 전송을 목적으로 하고 있다. 본 고에서는 MMT 제안 기술로서, 유선망에 비해 채널의 변화가 많은 무선망에서 효과적인 멀티미디어 전송을 위해 제안된 크로스레이어 디자인(Cross Layer Design-CLD)에서의 신호세기(signal strength information) 활용 방법을 소개한다. 무선환경에서 신호세기를 활용하면 매우 효율적인 멀티미디어 전송이 가능함은 관련 연구 논문[1]-[5]을 통해 증명되었다. 하지만, 무선채널의 특성상 서로 다른 신호세기의 범위를 사용함으로써 신호세기 정보의 유용성에도 불구하고 레이트 어댑테이션 애플리케이션에서 활용하는데 제한이 있어왔다. 따라서 본 논문에서는 MMT 표준화 기술 기고로 제안된 무선채널 신호세기 정보의 범위를 표준화된 형식으로 활용하는 방법에 대하여 기술한다.

This paper examines the persistent properties of 12 sectoral relative prices between Korea and Japan obtained following the Classification of Individual Consumption according to Purpose (COICOP) over the period of 1985-2016. Applying a new econometric method developed by Pesaran which controls for the cross-section dependence in a panel, we are not able to reject the hypothesis that the sectoral real exchange rates contain a common stochastic trend. On the other hand, the well-known panel unit root tests such as the IPS and LLC tests widely used by previous studies strongly reject the unit root hypothesis. Since the error term of the regression for our panel exhibits significant cross-section dependence, these opposite results justify that the use of the new econometric method is appropriate.

An ultra-high voltage (UHV) transmission system has the advantages of low circuitry loss, high bulk capacity and long-distance transmission capabilities over conventional transmission systems, but it is easier for this system to cross fault rupture zones and become damaged during earthquakes. This paper experimentally and numerically investigates the seismic responses and collapse failure of a UHV transmission tower-line system crossing a fault. A 1:25 reduced-scale model is constructed and tested by using shaking tables to evaluate the influence of the forward-directivity and fling-step effects on the responses of suspension-type towers. Furthermore, the collapse failure tests of the system under specific cross-fault scenarios are carried out. The corresponding finite element (FE) model is established in ABAQUS software and verified based on the Tian-Ma-Qu material model. The results reveal that the seismic responses of the transmission system under the cross-fault scenario are larger than those under the near-fault scenario, and the permanent ground displacements in the fling-step ground motions tend to magnify the seismic responses of the fault-crossing transmission system. The critical collapse peak ground acceleration (PGA), failure mode and weak position determined by the model experiment and numerical simulation are in relatively good agreement. The sequential failure of the members in Segments 4 and 5 leads to the collapse of the entire model, whereas other segments basically remain in the intact state.

A push pull hood system is frequently applied to control contaminants evaporated from an open surface tank in recent years. Efficiency of push pull hood system is affected by various parameters, such as cross draft, vessel shapes, size of tanks surface, liquid temperature, and so on. Among these, velocity of cross draft might be one of the most influencing factor for determining the ventilation efficiency. To take account of the effect of cross draft velocities over 0.38m/s, a flow adjustment of ${\pm}$20% should be considered into the push and +20% into the pull flow system Although there are many studies about the efficiency evaluation of push pull hood system based on CFDs(Computational Fluid Dynamics) and experiments, there have been no reports regarding the influence of velocities and direction of cross-draft on push-pull hood efficiency. This study was conducted to investigate the influence of cross draft direction and velocities on the capture efficiency of the push-pull ventilation system. Smoke visualization method was used along with mock-up of push-pull hood systems to verify the ventilation efficiency by experiments. When the cross-draft blew from the same origins of the push flows, the efficiency of the system was in it's high value, but it was decreased significantly when the cross-draft came from the opposite side of push flows Moreover, the efficiency of the system dramatically decreased when the cross-draft of open surface tank was faster than 0.4m/s.

본고는 촉한(蜀漢)의 무장(武將)에서 출발하여 신(神)으로 추앙받고 있는 관우의 생명력을 역대 왕조의 정치적 측면에서 찾았다. 관우는 위진남북조(魏晉南北朝) 시대에는 일개 장군으로 묘사되었지만, 수당(隋唐) 시대를 거치며 무성왕묘(武成王廟) 종사(從祀)를 통해 국가 사전(祀典)에 편입되었고, 다시 송원(宋元)시대에는 '후(侯)'에서 '공(公)'으로, 다시 '공(公)'에서 '왕(王)'으로 신분의 급상승을 이루었다. 관우 신격화가 절정에 이른 명청(明淸) 시대에 이르면, '왕(王)'을 넘어 '제(帝)'로 등극하면서 삼계(三界)를 통섭하는 최고의 권능을 부여받게 된다. 그는 백성에서부터 사대부에 이르기까지 생활신앙과 도덕 정신에 영향을 미쳤고, 결국은 정신적 수호신(守護神)으로 존재할 수 있었다. 역사상 통치자가 관우(關羽)에게 내린 봉호(封號)는 다양했지만, 그 속에는 국가의 재난 해소와 봉건통치의 유지와 보호라는 정치적 필요성이 깔려 있었다.

이 논문은 21세기 한국과 중국, 일본, 대만에서 제작, 유행한 TV 드라마 <꽃보다 남자>를 연구대상으로 하여 동북아시아의 문화융합을 살펴보고 이 지역 대중이 공유하는 문화적 취향을 귀납하였다. 일본 만화를 원작으로 한 4개국의 <꽃보다 남자>는 원작이 지니고 있는 기본적인 서사구성을 토대로 캐릭터의 설정과 서사공간의 혼합, 소비주의적 욕망의 재현에서 각국의 사회적이고 문화적인 특수성을 재현하였다. 이를 통해 수용자들은 동북아시아 각국의 사회문화적 환경이 자연스럽게 혼성적으로 결합된 서사를 접하게 되는 것이다. 한편 로맨스 플롯을 기본으로 전개되는 TV 드라마 <꽃보다 남자>는 원작인 만화에서 가능했던 구성적 특질이 매체변환 과정에서도 드러나고 있다. 특히 전통적인 성 관념에서 탈피한 남성 캐릭터의 설정과 독립적인 여성 캐릭터의 재현을 통해 미래의 역할 모델을 제시하는 순정만화의 상상력이 동북아시아 대중들에게 공유되고 있다. <꽃보다 남자>의 주 수용자 계층인 10-20대 초반 젊은 여성들의 이해에 기반한 감수성과 취향이 21세기 동북아시아에서 공유되고 유행한다는 점은 "소녀"의 부상이라는 점에서 주목을 요한다. 부르주아 가족 구조를 단위로 하는 현대 자본주의 체제에서 엄격한 보호와 구속의 대상이었던 소녀는 21세기 동북아시아 대중문화콘텐츠 산업에서 중심 소비자로서 자리를 확고히 했음을 보여주기 때문이다.
