The purpose of this study is to investigate how the types of perceived brand image related to the main concept building brand equity affect 'brand preference' and 'behavioral intentions'. The perceived brand image is set as the brand image type perceived by the consumer from the image pursued by the corporate brand, while in addition to brand preference, behavioral intentions are set as purchase intention and recommendation intention for the result variables. The result shows that the types of perceived brand image were extracted as 'factor 1(challenge spirit)' and factor 2(reliability) and through the cluster analysis 3 groups under each type were identified. Also, a significant difference between the influence of each type of perceived brand image on 'brand preference', 'purchase intention' and 'recommend intention' was indicated. In addition, the differences of perceived brand image types were found to be higher in order of 'challenge spirit type', 'reliability type', 'integrated type'. The empirical implementation of this study lies in the fact that it classifies the concept of brand image not as a broad theoretical model, but as a model directly related to real consumer perception, and that it gives practical suggestion for brand image management related to advertising.

This study aimed at investigating the effects of sub-variables of elderly people's lifestyle health and leisure oriented pursuits, outdoor and challenge pursuits, security and material pursuits, family oriented pursuits, and peer oriented pursuits on what they perceive to be successful later years. The background of this study was that there has been few study on the older population in Korea with focus on their cultural and traditional norms. The objective of this study was to investigate the effects of elderly people's lifestyle on what they perceive to be successful later years, thereby identifying practical implications for better social welfare associated with successful later years. Analysis was carried out of self reported questionnaires and self-interviews with elderly people aged over 65 frequenting a welfare center for elders and a community center in a city in Korea. In order to examine the effects, a reliability test, a descriptive analysis, a correlation analysis, and a multi-regression analysis were performed. The results of the analysis for sub-variables of lifestyle showed that health and leisure oriented pursuits, outdoor and challenge pursuits, security and material pursuits, family oriented pursuits, and peer oriented pursuits had significant positive impact on successful later years. The two most influential were peer oriented and family oriented pursuits. Drawing on the results, this study suggests that what is needed for dejected and lonely elderly members in the society is to provide them with opportunities for developing and keeping good relationships with friends and family members and there is a need for a system where old people, as consumers of cultural capital, can have easy access to a variety of cultural resources and activities at a local and regional level.

Original play of theatrical troupe Yeonwoo Stage has gone through history represented by (i) the development period of "research on play," (ii) the resistance/growth period of "play movement," (iii) the prime/segmentation period of "metaphor for reality," (iv) the crisis/transition period of "rediscovery of reality," and (v) the challenge/advancement period of the "active development of repertoire." "Collective creation" based on the singe-representative system was a solution to overcome difficult circumstances, crisis facing the theatrical troupe and the lack of resources in the development period and the resistance/growth period, "co-creation" based on the five-representative system, the two-representative system, the system of an operation committee consisting five members, etc. in the prime/segmentation period and the crisis/transition period, and "planning and production" based on the single-producer system in the challenge/advancement period. "Collective creation" system was operated by the entire theatrical troupe, which was led by a director; "co-creation" system was operated by performers, who were directed by a director (-playwriter); and "planning and production" system was operated both internally and externally and was led by a producer. During its long history of developing original play, Yeonwoo Stage has (i) expanded the scope of Korean-style narrative, (ii) succeeded collective creation culture to the next generation, (iii) followed the trend of the times, (iv) attempted to attract popular empathy.

Lifestyle is an important variable to understand consumer behavior because it is a lifestyle that is common to all members of society or some members of society. so In this study, the survey has been performed on adult mobile game users over the age of 20 in Korea and China to evaluate the correlation between lifestyle and will of continuous use of game by mobile game users, and the hierarchical multiple regression analysis has been performed on the collected data by using the statistical package program SPSS 20.0. There were total 212 respondents with the gender ratio of 50:50, and 107 respondents were Korean, and 105 respondents were Chinese. As a result of study, first, regardless of lifestyle, more male and more Chinese respondents showed higher will of continuous use. Second, among mobile game user lifestyles, the challenge-oriented, trend-oriented, conservative, and ostentatious lifestyles could become significant causal variables for the will of continuous use of game. Yet, the influence of such lifestyle was not correlated with individual genders or nationalities. The result of this study will be provided as the basic data to establish the strategic solution for companies and government policies for entrance into the mobile game market of China in the future.

The purpose of this study is to analyze the characteristics and stigma of children and adolescents, and the message types for them in NPO's fundraising advertisement videos in Korea. The subjects are 152 children and adolescents in 147 videos from seven major non-profit organizations. The analysis tools were constructed based on prior studies, and it was carried out after preliminary study. The results are as follows. First, the characteristics of children and adolescents indicated that the ratio of children and infants, main-role, poverty situation, one-parent family, and ward-role appeared the most. Second, 'general' was the highest in the stigma format, and 'hazard' and 'mark' was high in the challenge format. Third, the stigma message was the highest in message type. Finally, as of 2014, the ratio of stigma message and value-exclusion message increased, and the ratio of challenge message and mixed message decreased. The research suggests that a paradigm shift in the format of NPO's typical fundraising advertisement videos is necessary, as the videos may not protect the human rights of children and adolescents and may have negative effects such as stigma.

One notable challenge in video searching and summarizing is extracting semantic from video contents and annotating context for video contents. Video semantic or context could be obtained by two methods to extract objects and contexts between objects from video. However, the method that use just to extracts objects do not express enough semantic for shot or scene as it does not describe relation and interaction between objects. To be more effective, after extracting some objects, context like relation and interaction between objects needs to be extracted from conversation situation. This paper is a study for how to detect speaker and how to compose context for talking to annotate conversation context. For this, based on this study, we proposed the methods that characters are recognized through face recognition technology, speaker is detected through mouth motion, conversation context is extracted using the rule that is composed of speaker existing, the number of characters and subtitles existing and, finally, scene context is changed to xml file and saved.

Due to the resource limitations of sensor nodes, providing a security protocol is a particular challenge in sensor networks. One popular method is the neighborhood-based key agreement protocol (NEKAP). NEKAP is an efficient and lightweight protocol, but it includes loopholes through which adversaries may launch replay attacks by successfully masquerading as legitimate nodes. In this paper, we present a modified security protocol for wireless sensor networks. We provide four types of keys for each node, which adapt to different security requirements; and an improvement is made to alleviate the replay attack. According to our qualitative performance analyses, the proposed security protocol provides effectiveness in terms of authentication security, attacking node detection, and replay attack resilience when compared to the conventional method.
