The purpose of this study was to determine the relationships among brand awareness, switching intentions, purchasing behavior, and revisiting intentions. Brand awareness consisted of three factors: brand image, physical environment, and affiliation of coffee brand. Good brand image was associated with reduced switching intentions, whereas negative images were associated with higher switching intentions. Consumer purchasing behavior was most affected by interior decoration, including furniture, decorations, etc. Switching intentions had a negative relationship with revisiting intentions. Finally, purchasing behavior and revisiting intentions showed a positive correlation. As limitations, the only participants were university students, who are not representative of all consumers at coffee shops. Moreover, this study did not divide coffee shops into franchises and individually owned.

인터넷의 급속한 확장으로 인해 네트워크 공격기법의 패러다임의 변화가 시작되었으며 새로울 공격 형태가 나타나고 있으나 대부분의 침입 탐지 기술은 오용 탐지 기술을 기반으로 하는 시스템이주를 이루고 있어 알려진 공격 유형만을 탐지하고, 새로운 공격에 능동적인 대응이 어려운 실정이다. 이에 새로운 공격 유형에 대한 탐지력을 높이기 위해 인체 면역 메커니즘을 적용하려는 시도들이 나타나고 있다. 본 논문에서는 데이터 마이닝 기법을 이용하여 네트워크 패킷에 대한 정상 행위 프로파일을 생성하고 생성된 프로파일을 자기공간화 하여 인체면역계의 자기, 비자기 구분기능을 이용해 자기 인식 알고리즘을 구현하여 이상행위를 탐지하고자 한다. 자기인식 알고리즘의 하나인 Negative Selection Algorithm을 기반으로 anomaly detector를 생성하여 자기공간을 모니터하여 변화를 감지하고 이상행위를 검출한다. DARPA Network Dataset을 이용하여 시뮬레이션을 수행하여 침입 탐지율을 통해 알고리즘의 유효성을 검증한다.

This study experimentally investigates the flexural behavior of steel-UHPC composite slabs composed of an innovative negative Poisson's ratio (NPR) steel plate and Ultra High Performance Concrete (UHPC) slab connected via demountable high-strength bolt shear connectors. Eight demountable composite slab specimens were fabricated and tested under traditional four-point bending method. The effects of loading histories (positive and negative bending moment), types of steel plate (NPR steel plate and Q355 steel plate) and spacings of high-strength bolts (150 mm, 200 mm and 250 mm) on the flexural behavior of demountable composite slab, including failure mode, load-deflection curve, interface relative slip, crack width and sectional strain distribution, were evaluated. The results revealed that under positive bending moment, the failure mode of composite slabs employing NPR steel plate was distinct from that with Q355 steel plate, which exhibited that part of high-strength bolts was cut off, part of pre-embedded padded extension nuts was pulled out, and UHPC collapsed due to instantaneous instability and etc. Besides, under the same spacing of high-strength bolts, NPR steel plate availably delayed and restrained the relative slip between steel plate and UHPC plate, thus significantly enhanced the cooperative deformation capacity, flexural stiffness and load capacity for composite slabs further. While under negative bending moment, NPR steel plate effectively improved the flexural capacity and deformation characteristics of composite slabs, but it has no obvious effect on the initial flexural stiffness of composite slabs. Meanwhile, the excellent crack-width control ability for UHPC endowed composite members with better durability. Furthermore, according to the sectional strain distribution analysis, due to the negative Poisson's ratio effect and high yield strength of NPR steel plate, the tensile strain between NPR steel plate and UHPC layer held strain compatibility during the whole loading process, and the magnitude of upward movement for sectional plastic neutral axis could be ignored with the increase of positive bending moment.

강-콘크리트 편개형 방폭문은 외피 구조로서의 강박스 내에 콘크리트 슬래브가 채워진 구조로서 힌지 및 렛치와 같은 지지부재에 의해 벽체에 고정되어 설치된다. 폭압이 작용하는 방향과 같은 정방향으로의 처짐 거동에 대해서는 많은 연구가 되어 왔으나, 부방향 처짐 거동에 대한 연구는 상대적으로 미흡한 수준이다. 본 연구에서는 폭압을 받는 편개형 방폭문의 부방향 처짐 단계에서 발생하는 반발 거동(rebound behavior)에 대해 유한요소해석으로 변수 분석을 하였다. 분석결과에 따르면 방폭문의 소성변형 내지는 파괴 정도, 반발작용 전후의 운동량 및 운동에너지 변화가 반발거동에 영향을 미치는 주요 요소로 분석되었다. 또한, 방폭문의 거동 특성이 준정적 영역에 속하는 경우에 비해 충격영역에 속하는 경우에서 더 큰 반발력이 발생하는 것으로 나타났는데, 이와 같은 결과는 변형에너지 보다 운동에너지가 상대적으로 더 크게 증가하는 충격영역에서의 거동 특성이 원인인 것으로 사료된다. 반발작용의 결과로 인해 지지부재에 과도한 변형이 발생할 수 있으므로 성능분석 및 설계 과정에서 이에 대한 고려가 필요하다. 또한, 부압이 미치는 영향을 검토한 결과에 따르면 강-콘크리트 방폭문의 경우에서도 반발에 의한 영향 및 부압 모두가 방폭문의 부방향 처짐에 기여할 때 반발력이 상대적으로 더 크게 증가하는 것으로 나타났다. 이와 같은 중첩 효과의 발생조건은 구조체 특성 및 폭발조건 등에 따라 다를 수 있으므로 이에 대해서는 더 많은 연구가 필요할 것으로 판단된다.

As the online space becomes more active, interest in protecting personal information is increasing. From this point of view, it is important to prevent personal information from being leaked in advance. As a precaution, it is suggested that users change their password periodically to protect their personal information effectively. Currently, various online services provide a request message that prompts users to periodically change their password. These messages are expressed as positive-centric or negative-centric. This message can be seen as a powerful way to trigger users' behavior. In this context, this study suggests that message framing type can be applied to the password change request message, and to investigate the difference between the positive-centric message and the negative-centric message. In addition, this study concluded that the effect of message type may be different depending on the degree of psychological ownership of the individual on the online service. As a result, users with high psychological ownership in online service were more effective when positive-centric message was presented than negative-centric message. On the other hand, users with low psychological ownership in online service were more effective when negative-centric message was presented than positive-centric message.

This study examines the relationship between perceived risk and regret, the influence of regret, and the regret-solution effort upon post-purchase behavior. These causal pathways are controlled by moderated different impulse buying types. The results of the study are three-fold. First, consumers with high social and convenience risks resulted in the high levels of regret. Second, the higher the regret then the higher the negative purchase intention and the lower the positive purchase intention. Consumers who emphasize the regret-solution have high positive purchase intentions and the low negative purchase intentions. Lastly, as for the influence of the regret upon the negative purchase intention, the 'recollection impulse buying type' has the greatest influence among all other types. No impulse buying types have a positive influence on purchase intention. As for the influence of the regret-solution efforts on the positive purchase intention, the 'pure impulse buying type' had the greatest influence. Only the 'suggestion impulse buying type' influenced the negative purchase behavior intention. The post-purchase intention depends on the level and the degree of the regret-solution efforts of the consumer. This study contributes to the examination of the different impulse buying types that influence the moderators in the causal pathway of the risk perception to the post-purchase buying behavior.

This study examined short-term longitudinal reciprocal relationships between maternal parenting behavior and preschoolers' compliance/noncompliance, as well as stability in both maternal parenting behavior and preschoolers' compliance/noncompliance over time. The sample which was used for this study was taken from a two-wave (one year apart) longitudinal study of preschool-aged children and their mothers (N = 53 dyads). At both times, mothers and their children were invited to a laboratory and engaged in 25 minutes of play involving three episodes of mother-child interaction. Maternal parenting behavior and preschoolers' compliance/noncompliance during play were coded using the Dyadic Parent-Child Interaction Coding System-III (DPICS-III). Maternal codes included positive, neutral, and negative parenting behaviors and child codes were comprised of compliance and noncompliance. The results revealed that during the play session, maternal neutral and negative parenting behavior and preschoolers' compliance were stable over time. In addition, T1 maternal negative parenting behavior was significantly related to T2 child compliance/noncompliance. However, T1 child compliance/noncompliance were not significantly associated with T2 maternal parenting behavior. These findings suggest that during the preschool period, there are unidirectional effects from mothers to children.
