Purpose - This study aims to explore the factors that can trigger the escalation of an initially pursued long-term utilitarian goal that is set aside to pursue a competing hedonic goal. Research Design, Data, and Methodology - The experimental study covered three groups : Group 1 (ego-depletion, self-referencing), Group 2 (ego-depletion, neutral), and Group 3 (no ego-depletion, neutral). The participants of the study comprised 150 undergraduates who were divided into three groups of 50 students for each. One-way ANOVA and regression analyses were used to verify the hypotheses. Results - Ego-depleted consumers are less likely to resist immediate temptation than those who are not in an ego-depletion state. Self-referencing has a positive impact on long-term goal reversion when consumers in an ego-depletion state experience immediate temptations. Counteractive construal plays a mediating role between self-referencing and long-term goal reversion. Conclusions - We found that consumers tend to yield to momentary temptations when they are in an ego-depletion state. Self-referencing and counteractive construal can eliminate the ego-depletion effect and then facilitates escalation of the set-aside long-term goal.

Personalized product recommendation service is receiving attention as a new marketing strategy while supporting consumer information search and purchasing decisions. This study attempted to verify the effect of self-reference on service use behavior through the dual path of cognitive attitude and emotional attachment. Using convenience sampling, an online survey was conducted with 324 women who were in their 20s and 30s. After collecting and compiling the survey data, the reliability and validity of variables constituting the conceptual research model were verified through confirmatory factor analysis using AMOS 22.0. Next, the significance of sequentially mediated pathways was verified using Process 3.5 Model 80. The results showed that self-referencing not only significantly affects service use intention by simply mediating cognitive attitudes but also sequentially mediates cognitive attitudes and additional information search. Furthermore, self-referencing was significant as an indirect path to service use intention by mediating additional information search. However, in the path mediated by emotional attachment, self-referencing was considered as a simple mediated path leading to service usage intention. These results indicate a dual path in the psychological mechanism, through cognitive and emotional evaluation, that prompts consumer behavioral responses to the personalized product information provided in the shopping process.

The current research aims to explore which type of identity-based message can be more persuasive for Chinese consumers to form positive restaurant brand attitude based on their cultural orientation, and to examine the roles of brand objective relevance and psychological power state in the persuasive process. The study employs a 2(identity expression focus: warmth vs. competence) × 2(message description manner: identity-defining vs. identity-referencing) × 2(experienced power state: high vs. low) between-subjects design, and conducts an online survey where 240 Chinese participants in total has responded to the questionnaires. SPSS and AMOS programs have been used to examine the hypotheses. The findings suggest that, first, the warmth-focused messages (identity-defining messages) more positively affected Chinese consumers' object relevance than the competence-focused messages (identity-referencing messages); Second, high power-experienced Chinese consumers rather than low power consumers tend to perceive more object relevance at the warmth self-defining messages; Third, brand object relevance revealed a mediation effect in the process of the warmth-focused messages (identity-defining messages) affecting brand attitude. This research offers new insight into the relationships between consumers' cultural orientation, understandings of power, and identity-based consumer behavior, suggesting marketers should take those social influences and consumer diversities into account when developing the message to persuade consumers.

The performance of a fiber Bragg grating strain sensor constructed with 3$\times$3 coupler is investigated. A 3$\times$3 coupler Mach-Zehnder (M/Z) interferometer is used as wavelength discriminator, interrogating strain-induced Bragg wavelength shifts. Two quadrature-phase-shifted intensities are synthesized from the as-coupled interferometer outputs, and digital arctangent demodulation and phase unwrapping algorithm are applied to extract the phase information proportional to strain. Due to the linear relation between the input strain and the output of quadrature signal processing, signal-fading problems eliminated. In the experiment, a fiber grating that was surface adhered on an aluminum beam was strained in different ways, and the photodetector signals were transferred and processed in a computer-controlled processing unit. A phase recovery fo 7.8$\pi$ pk-pk excursion, which corresponds to ~650$\mu$strain pk-pk of applied strain, was demonstrated. The sensor system was stable over the environmental intensi쇼 perturbations because of the self-referencing effect in the demodulation process.

A shear-deformable finite element model (FEM) with five nodes and thirteen degrees of freedom (DOFs) for free vibrations of laminated composite beams with arbitrary lay-up is presented. This model can be capable of considering the elastic couplings among the extensional, bending and torsional deformations, and the Poisson's effect. Lagrange's principle is employed in derivation of the equations of motion, and thus the element matrices are obtained. Comparisons of the present element's results with those in experiment, available literature and the 3D finite element analysis software (ANSYS(R)) are made to show its accuracy. Some further results are given as referencing for the future studies in vibrations of laminated composite beamst.

디지털 영상콘텐츠 분야에서의 원소스 멀티유스(One-Source Multi-Use) 전략은 하나의 소재(onesource)로 다양한 상품(multi-use)을 개발, 배급할 경우 시장에서의 시너지효과가 크다는 판단에 의해 서로 다른 장르에 적용하여 파급효과를 노리는 마케팅관점에서 중시된 이론으로 알려져 있다. 최근 문화산업재의 온라인화 및 디지털 콘텐츠화가 급진전되고 각 장르간 경계가 모호해지고 매체간 이동이 용이해짐에 따라 이 전략은 창구효과(Window Effect)가 큰 문화산업의 특성에 맞추어 기획 단계부터 영화 게임 애니메이션 캐릭터 등을 총 망라하는 문화 콘텐츠를 개발뿐만 아니라 플랫폼 재활용측면에서 소프트웨어엔지니어링 분야까지 확장되고 있는 추세이다. 특히 하나의 인기 소재만 있으면 추가적 비용부담을 최소화하면서 다른 상품으로 전환해 높은 부가가치를 얻을 수 있다는 점에서 각광받고 있으며, 관련 상품과 매체를 체계적으로 관리할 수 있어 마케팅 및 홍보 플랫폼 제작 등에서 제작비용 절감효과를 누릴 수 있다는 장점이 있다. 이러한 관점에서 본 연구는 세계적으로 영상콘텐츠산업 비중이 높은 한 미 일 3국의 제작방식의 비교를 통하여 각국이 선호하는 장르 및 제작방식을 고찰하고자 한다.

온라인에서 추천시스템은 사용자들의 구매 이력 또는 선호도를 바탕으로 적절한 콘텐츠 또는 서비스를 제공하는 IT기술이다. 추천시스템에 대한 사용자의 평가에는 추천 결과에 기반한 시스템 성과와 추천 방식에 의해 형성되는 사용자의 태도에 대한 두 측면 모두 고려되어야 한다. 그러나 시스템 성과와 사용자 태도에 대한 통합적 관점의 추천시스템 평가에 대한 연구는 많지 않았다. 본 연구의 목적은 추천시스템에 대한 사용자 평가의 통합적 관점을 제시하는 것에 있다. 그에 따라 사용자 태도 형성과 관련하여 자기 참조(Self-reference)와 사회적 실재감(Social Presence)의 정도를 구분하여 웹 기반 실험을 수행하였으며 추천시스템의 성과 측정을 위하여 추천 알고리즘 평가에 널리 활용되어 온 정확성(Accuracy)과 새로움(Novelty)을 활용하였다. 연구의 결과로 추천시스템의 사용자 만족에 미치는 변수로 정확성과 새로움이 시스템 특성 요소로 제시되었으며 사용자 태도 관점에서 사회적 실재감이 사용자의 만족에 영향을 주었다.

In this study we classified sediment types of tidal flat using Landsat-5 images. This is for groping the method which can analyze correctly various kinds of sediment faces through satellite images. This work was performed by referencing ground truth of sediment faces which was investigated in the field. With this data we classified Landsat-5 image of 1997's to grope a most suitable classification method. As a result, in case of south Kanghwa island area, it was the optimum way to compound band 4, 5, 7 of Landsat-5 TM imagery. And, this work classified 3 kinds of sediment faces - M(mud), sM(sandy mud) and (g)M(slightly gravelly mud) - in land and mixed water area. It is anticipated that if this method is applied to a image of extremely lower sea level time, it can classify the sediment types of a broad tidal flat area. This is expected to be a beginning of estimating the effect of sediment faces to the change of the tidal flat ecosystem.

바이러스 감속기(virus throttling)은 연결요청 패킷의 전송비율을 일정 비율 이하로 제한함으로써 웜을 탐지하는 대표적인 조기 웜 탐지 기술 중의 하나이다. 기존 바이러스 감속기 연구에서는 웜 탐지시간에는 크게 영향을 미치지 않으면서도 연결설정 지연시간을 단축시키기 위해 가중치 평균 지연 큐 길이를 적용하여 비율 제한기의 주기를 자율적으로 조절하였다. 기존 연구에서는 비율 제한기의 최소주기를 고정하고 또한 주기 값을 감소시키다가 다시 증가시키기 시작하는 반환점도 미리 고정하였다. 그러나 이러한 두 성능결정 요소는 웜 탐지시간과 연결 설정 지연에 서로 다른 영향을 미친다. 따라서 본 논문에서는 가변 비율 제한기의 최소주기와 반환점이 어떤 영향을 미치는지 실험을 통해 분석하고, 상황에 따라 이들 성능결정 요소들의 값을 결정할 수 있는 방안을 제시하고자 한다. 제안된 방법은 성능결정 요소를 고정시킨 기존 방법보다는 웜 탐지시간이나 연결설정 지연시간 단축에 더 효율적이라는 사실을 실험을 통해 확인하였다.
