In this paper, we present some results on performance analysis for flap actuation system of aircraft. For this, by utilizing MATLAB/Simulink solution, which is widely used physical model-based design tool, we particularly construct the architecture of the analysis model consisting of the main three phases: 1)commanding and outer-controlling the flap angle through flight control computer; 2)generating hydraulic/mechanical power through control module and power drive unit; 3)transmitting torque and actuating the flap through torque tube and rotary geared actuators. For mimicking the motion of the actual flap, we apply each mechanical component, which is already being used in actual aircraft, to our performance analysis model so that it guarantees the congruency of the simulation results. That is, we reflect the actual specifications of flap hardware and software as parameters of the model. Finally, simulation results are presented to illustrate the model.

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.

현 교육과정에서 이차함수 그래프에 관한 교수-학습은 대수적 조작에 의한 완전제곱형식으로의 변환을 강조하고 이미 선행한 일차함수의 그래프와는 무관하게 다루어지고 있다. 본 논문은 이차함수 그래프의 구조적 특성이라 할 수 있는 대칭성, 꼭지점 및 합동에 대한 기하적인 근거를 일차함수의 그래프에 기초하여 분석하고 이것의 결과를 구체적 이차함수에 대해 그 꼭지점의 좌표 및 절편을 찾는 데 적용한다. 본 연구는 이차함수 그래프의 구조적 특성을 일차함수의 그래프와 기하적으로 연결시키는 데 의의가 있으며 그 기하적인 과정은 완전제곱형식의 대수적 절차로 연결된다. 이러한 연결은 일차함수의 그래프에 대한 이해가 이차함수의 그래프에 대한 이해로 전이되어 이차함수에 대한 기하적인 이해를 넓히는 교수-학습방법이 될 수 있을 것이다.

Influences of convergent services on the overall industry has become noticeable. Various services are becoming to converge into a single platform because of ever-hanging needs of digital service users. However, few studies have investigated how users' perception of convergent services as well as the quality of experience that service users have while using the convergent services. Therefore, this study aims at identifying perceived patterns of convergent services by IPTV users, which is one of the representative convergent-ervice platforms. It also aims at identifying the impact of perceived convergence pattern on the relationship between goal congruency among individual services and the quality of user experience. Two empirical studies were conducted to accomplish the research goals. We have constructed two prototypes of convergent digital services in the IPTV environment and conducted controlled experiments to verify the research hypotheses. The results indicate that design similarities of two services substantially influence the perceived patterns of convergent services. It was also found that the perceived convergent patterns have significant moderating effects on the impact of perceived goal congruence upon the quality of user experience. This paper ends with limitations as well as implications of the study results.

This study empirically investigates the design factors that could engender positive impacts on consumers' user experiences with respect to trust, attitude, and intent to purchase a product promoted in the virtual reality (VR) e-commerce environment. Guided by previous literature, we specifically test the role of schema congruity due to the design of the space and virtual agent on trust, attitude, and purchase intention in the context of VR e-commerce. To test the effect of the congruency between user's schema and virtual environment design on user intentions, a 2 × 2 mixed ANOVA design experiment was conducted with place creativity (Low vs. High) as a within factor and workplace attire (Casual vs. Formal) as a between factor. The result showed support for the effect of schema congruity on trust, in that interaction of the two factors were found. Significant positive relationship between trust, attitude, and purchase intention was found. Further implications are discussed based on results.

This research aimed at studying the role of self-enhancing imagery and self goal-achievement emotion in the effect of characteristics perceived at advertisements using multisensory cues on purchase intention. Sports shoes advertisement was selected as an empirical research object. Questionnaire survey method was used to collect data. 'WenJuanXing' site was used to make the questionnaire in Chinese, and it was loaded on WeChat and QQ. 260 participants from different regions of China participated in online questionnaire survey. The results of testing the hypotheses by structural equation model in Amos 21.0 program are summarized as followings. The congruency between multisensory cues and self-discrepancy awareness positively evoked the self-enhancing imagery and the self goal-achievement emotion. The object relevance between the consumer and the product advertised did not induce the emotion, but evoked the self-enhancing imagery. Both of the self-enhancing imagery and the self goal-achievement emotion had positive effects on the product purchase intention. When developing advertisement, marketers should focus on multisensory cues' characteristics to enhance the self-enhancing imageries as well as to help feel the goal-achievement emotion. They should pay attention to the ways by which the multisensory cues' characteristics used to develop advertisement can be perceived to be congruent with each other by consumers.

The purpose of this study is to investigate the effect of Brand Personality to Marine Tourism Destination Images and Intention to Recommend. For this purpose, factor analysis was applied to 42 of J.Aaker's Brand Personality Scale and 5 personality dimensions were extracted. This analysis was also applied for cognitive and affective images and two of cognitive images and three of affective images were extracted. Multiple regression was done to estimate the relative effects of Brand Personality to both cognitive and affective images and intention to recommend. The results indicated brand personality influenced on both cognitive and affective images and intention to recommend directly and also found affective images was influenced by cognitive images. The results also suggested useful insight for future study. The Brand Personality Scale which developed for the product by Aaker might not be suitable for measuring the marine tourism destination brand personality and necessary to develop the new scale suitable for marine tourism destination personality, and be needed to study together with other moderating variance such as satisfaction and congruency with image to verifying the exact effect between different variables.

This paper describes a preliminary work on prosody modeling aspect of a text-to-speech system for Thai. Specifically, the model is designed to predict symbolic markers from text (i.e., prosodic phrase boundaries, accent, and intonation boundaries), and then using these markers to generate pitch, intensity, and durational patterns for the synthesis module of the system. In this paper, a novel method for annotating the prosodic structure of Thai sentences based on dependency representation of syntax is presented. The goal of the annotation process is to predict from text the rhythm of the input sentence when spoken according to its intended meaning. The encoding of the prosodic structure is established by minimizing speech disrhythmy while maintaining the congruency with syntax. That is, each word in the sentence is assigned a prosodic feature called strength dynamic which is based on the dependency representation of syntax. The strength dynamics assigned are then used to obtain rhythmic groupings in terms of a phonological unit called foot. Finally, the foot structure is used to predict the durational pattern of the input sentence. The aforementioned process has been tested on a set of ambiguous sentences, which represents various structural ambiguities involving five types of compounds in Thai.

The 583 employees as subject for empirical analysis were selected by cluster sampling method in Banwol & Sihwa Industrial complex in Ansan area. This study shows the followings; 1. In the group where the task is unstructured and the subordinate's ability is high, the achievement-oriented and participative leader behavior have positive impact on the subordinate's expectancy. 2. In the group where the task is unstructured and the subordinate's ability is low, the directive leader behavior has positive impact on the subordinate's expectancy. 3. In the group where the task is structured and the subordinate's ability is high, the supportive leader behavior has positive impact on the subordinate's expectancy. 4. In the group where the task is structured and the subordinate's ability is low, only supportive leader behavior has positive impact on the subordinate's expectancy, and the directive leader behavior has no significant impact. 5. The subordinate's need for growth has a strong moderating effect in the relationship between leader behavior and job satisfaction. Finally this study indicates the implication for future theoretical and empirical development.
