Myocardial blood low (MBF) in human can be noninvasively quantified using dynamic N-13 ammonia PET and two-compartment tracer kinetic model. In this study, factor analysis was used to extract the "pure" blood-pool time-activity curves (TACs) and to generate actor images. ive human N-13 ammonia PET dynamic studies were obtained. Three actors and their corresponding actor images were extracted rom each study. The accuracy of MBF estimated by the actor analysis (FA/FA MBF) was examined by comparing to the values estimated using the conventional ROI method (ROI/ROI MBF). MBF obtained by the actor analysis linearly correlated with MBF obtained by the ROI method (slope=0.98, r=0.91). Input unctions obtained by the two methods agreed well. In conclusion, MBF can be measured accurately and noninvasively with dynamic N-13 ammonia PET imaging and actor analysis. This method is simple and acurate and can measure MBF without blood sampling, ROI drawing nor spillover correction.

Objectives: The purpose of this study was to investigate a role of self-compassion in conflict resolution strategies among dating couples. Further, we examined conflict resolution strategies as mechanisms to explain in the relationship between self-compassion and relationship satisfaction. Method: Two hundred forty two dating couples were recruited. Actor and Partner Independence Model(APIM) was used to examine actor and partner effects of self-compassion on relationship satisfaction as well as conflict resolution strategies. The total of 4 APIMs, two positive conflict resolution strategies(i.e., positive emotional reactions, active coping) and two negative conflict resolution strategies(i.e., negative emotional reactions and hostility, avoidance) were analyzed. Positive conflict resolution strategies had only actor effect in the link between self-compassion and relationship satisfaction. That is, self-compassionate men and women were more likely to use positive conflict resolution strategies and, in turn, led to their higher relationship satisfaction. Both actor and partner effects were found in the negative conflict resolution strategy models. In terms of actor effect self-compassionate men and women were less likely to use negative conflict resolution strategies and that, in turn, led to their higher relationship satisfaction. In terms of partner effects we found that women's negative emotional reactions and hostility mediated the link between women's self-compassion and their male partners' relationship satisfaction. Men's avoidance mediated the link between men's self-compassion and their female partners' relationship satisfaction.

The purpose of this study is to research development process of commedia dell'arte and Korean masque that have similar figure, grasp similarity and difference and find the meaning of masque and costume in both theatrical arts. Italian commedia dell'arte and Korean masque are performed by wearing standardized mask and costume depending on the role. As common points, first, the characters have unique names and possess unique features of character, costumes, masks and playing styles. Through the feature, the audiences can understand role of actor and the actors can devote themselves to their role by wearing masks and costumes. Second, although background plays an important role in commedia dell'arte, the role of costume is more important. Because masque speaks for poverties of general people indirectly, the costumes of general people were used as they are. As different point, first, most of Korean masks cover entire face, restricting speech of actor but masks of commedia dell'arte cover only upper part of face and expos mouth and chin of actor, enabling actors to express various emotions depending on the character. Second, priority is given to personality of actor and origin area and current silhouette, material and color that changed by century is reflected in the costume of commedia dell'arte but silhouette, material and color of the Age of Joseon Dynasty were adopted in Korean masque.

This study aimed to examine the actor and partner effects of marital satisfaction on life satisfaction in middle-aged and older couples via their health behavior and health. The study participants included a total of 2,108 couples, aged 57 and over, from the eighth wave of data from the Korean Longitudinal Study of Ageing (KLoSA). The marital satisfaction, health behavior, health, and life satisfaction of the husbands and wives were measured to conduct the analysis. This analysis was conducted based on the Actor-Partner Interdependence Mediation Model (APIMeM) with the bootstrapping technique being used as the mediating effect. The results indicated that there were significant actor and partner direct and indirect effects when it comes to the relationship between the participants' marital satisfaction and their own life satisfaction, mediated by health behavior and health. However, no significant influences regarding the health of the participants on the life satisfaction of their spouses were found. These results suggest that it is important for middle-aged and older couples to improve their marital relationships in order to promote the health and life satisfaction of both parties. Doing so will help husbands and wives lead healthier lifestyles based on their positive relationships.

Objective: The current study examined whether providing both an actor's eye gaze and emotional expressions can help 10-month-olds interpret a change in the actor's words as a signal to a change in the actor's goal object. Methods: Sixteen 10-month-olds participated in an experiment using the violation-of-expectation paradigm and were compared to 16 10-month-olds in a control condition. The infants in the experimental condition were familiarized to an event in which an actor looks at one of two novel objects, excitingly utters a sentence, "Wow, here's a modi!", and grasps the object. The procedure in the control condition was identical to that of the experimental condition except that the infants heard the sentence without any emotional excitement and the eye gaze of the agent was hidden by a visor. In the following test trial, the infants in both conditions heard the agent changing her word (from modi to papu) and watched her grasping either the same object as before (old-goal event) or the new object (new-goal event). Results: The infants in the experimental condition looked at the old-goal event longer than at the new-goal event, suggesting that they expected the agent to change her goal object when the actor changed her word. However, the infants in the control condition looked at the two events about equally. Conclusion: When both eye gaze and emotional cues were provided, 10-month-olds were able to exploit the agent's verbal information when reasoning about whether the agent would pursue the same goal object as before.

As more consumers avoid ads aided by advanced technologies that conveniently block ads, traditional advertising is becoming less effective than ever before. Product placements are increasingly executed to unobtrusively expose products and brands to consumers while they watch media programs. The current study attempts to enhance our understanding of the factors that affect consumer attitude towards the brands placed in TV dramas. In particular, this study examines whether the attractiveness of actors and the congruency between the products placed and the story of the TV drama influence consumer attitudes towards the TV drama and the brand. A total of 211 male consumers in their 20s and 30s were used for data analyses. Structural equation modelling revealed that the product-story congruence had a positive impact on consumer attitude towards the TV drama as well as their attitude towards the brand. Actor attractiveness (in terms of similarity and likability) positively influenced consumer attitude towards the brand. Only the perceived likability dimension of actor attractiveness was found to affect consumer attitude towards the TV drama.

This study examined that the effects of fathers-in-law's and mothers-in law's acceptance-rejection on husbands' and wives' psychological well-being using APIM. Participants were 265 couples living Seoul KyungKi-do and JeJu Island, and their mean age was 39.16 (husbands, SD=7.39) and 36.45 (wives, SD=7.36), respectively. The results of APIM showed that, in father-in law model, actor effects of husbands (the influence of fathers in law acceptance-rejection for husbands on husbands' psychological well-being) were more significant than actor effects of wives (the influence of fathers-in-law's acceptance-rejection for wives on wives' psychological well-being), while partner effects of wives (the influence of fathers in law acceptance-rejection for wives on husbands' psychological well-being) more significant than partner effects of husbands (the influence of fathers' in law's acceptance-rejection for husbands on wives' psychological well-being). In mother-in law model, there were no significant differences both between actor effects of wives and actor effects of husbands, and between partner effects of wives and partner effects of husbands.

최근 센서 네트워크는 다양한 분야에서 응용되고 있으며 활발한 연구가 진행되고 있다. 그러나 센서 네트워크는 특정 현상에 대한 정보를 수집하고 이를 외부의 네트워크 관리자에게 전송하고 관리자는 전송된 정보를 이용하여 대응하는 형태로 구성되어 있어 사건에 대한 즉각적이고 적시적인 대응이 어렵다. 이러한 문제점을 극복하기 위해 센서 네트워크에 이동성과 활동성을 가져 즉시적인 대응능력이 있는 액터 노드를 포함하는 무선 센서 및 액터 네트워크(WSANs)가 제안되었다. WSANs는 센서 네트워크와 여러 측면에서 많은 공통점을 가지고 있으나, 노드들이 동등한 권한과 능력을 가지는 센서 네트워크와는 달리 자원제약이 적고 이동성을 가지는 액터 노드를 포함하고 있어 기존의 보안기술을 적용하기에는 어려움이 많다. 따라서 본 논문은 WSANs를 안전하고 효율적으로 운용하기 위해 요구되는 기밀성, 무결성, 인증 등의 보안 서비스를 제공하기 위해, 네트워크를 노드의 능력에 따라 계층적으로 구분하고 액터 하위 계층에는 일대일키(Pair-wise Key), 노드키(Node Key), 지역키(Region Key)를 활용한 키관리 프로토콜을 액터 상위 계층에는 공개키 기반의 키관리 프로토콜을 제안한다.
