This study explores 1) the cultural meanings that television beauty programs deliver, 2) the ways consumers consume TV beauty programs, and 3) the differences in the meaning of television beauty programs according to personality types. An Enneagram was used to define different personality types. The Enneagram explained personalities according to underlying core energies and was useful to grasp consumer behavior. Exploratory data were collected through in-depth interviews of fifteen women in their twenties who watched television beauty programs regularly. The personality types were classified according to three core energies: head-centered, heart-centered, or body-centered. The results were: First, television beauty programs were celebrity-focused, product-focused, and consumer-focused. They were found to help consumers improve their appearance in an appearance-oriented contemporary society by sharing appearance management information. Second, consumers consumed the products from television beauty programs as well as sought a "beautifully transformed self". Third, cultural meanings moved first from a culturally-constituted world to consumer goods through television beauty programs that then moved these goods to the individual consumer through symbolic consumption behavior along with grooming rituals, evaluation practices, appreciation practices, and accounting practices. Symbolic consumption behavior differed with personality type: heartcentered consumers transferred meaning through grooming rituals and appreciation practices, head-centered consumers through evaluation practices, and body-centered consumers through accounting practices.

Due to the implementation ease and alleviation of memory bottleneck effect, NUMA architecture has dominated in the multiprocessor systems for the past several years. However, because the NUMA system distributes memory in each node, frequent remote memory access is a key factor of performance degradation. Therefore, efficient design of RAC(Remote Access Cache) in NUMA system is critical for performance improvement. In this paper, we suggest Multi-Grain RAC which can adaptively control the RAC line size, with respect to each application behavior Then we simulate NUMA system with multi-grain RAC using MINT, event-driven memory hierarchy simulator. and analyze the performance results. At first, with profile-based determination method, we verify the optimal RAC line size for each application and, then, we compare and analyze the performance differences among NUMA systems with normal RAC, with optimal line size RAC, and with multi-grain RAC. The simulation shows that the worst case can be always avoided and results are very close to optimal case with any combination of application and RAC format.

Virtual Communities, which are formed on the Internet, are expected to serve the needs of members for e-collaboration, e-communication, information and knowledge sharing. The executives of organizations should consider virtual community as a new innovation or knowledge pool since members share knowledge. However, many virtual community have failed due to members' low willingness to engage and furthermore to share knowledge with other members. Thus, there is a need to understand and foster the determinants of members' sense of belonging behavior in virtual community. This study develops an integrated model designed to investigate and explain the relationships between contextual factors, personal perceptions of virtual community, usability, trust and sense of belonging in using a certain virtual community. Empirical data was collected from 201 and tested using structural equation modeling (SEM) to verify the fit of the hypothetical model. The results show that the perceived usability and community trust of members significantly influences sense of belonging in using the virtual community, and information quality, system quality, familiarity on the virtual community are significantly influence the usability but not reputation. And I confirmed that perceived shared vision and responsiveness play the role of determinants in making the member's trust, perceived risk influence the making community trust in directly. The results of the study can be used to identify the motivation underlying members' sense of belonging in a certain virtual community by investigating the impacts of contextual factors and personal perceptions on virtual community, the integrated model better explains behavior than other proposed models. This study might help executives of virtual communities and organizations to manage and promote these determinants of sense of belonging to stimulate members' willingness to engage the community and futhermore enhance their virtual community loyalty.

Purpose: This study aimed to examine the effect of spouses participating in health coaching on stage of the change, health behaviors, and physiological indicators among male office workers with cardiocerebrovascular disease (CVD) risk factors and compare the findings with trainers who provided health coaching only to workers. Methods: A quasi-experimental pretest-posttest design was used. Convenience sampling was used to recruit participants from a manufacturing research and development company in the city of Gyeonggi province. The health coaching program for the experimental group (n=26) included individual counseling sessions according to workers' stage of change, and provision of customized health information materials on CVD prevention to workers and their spouses for 12 weeks through mobile phone and email. Results: After 12 weeks of intervention, the total score for health behavior, and scores on the sub-areas of exercise and health checkups significantly improved in the experimental group, but there were no significant differences in the scores of stage of the change and physical indicators. The results of a paired t-test showed a significant decrease in the body mass index, abdominal circumference, systolic blood pressure, diastolic blood pressure, total cholesterol and triglyceride values, and a significant increase in the high-density lipoprotein cholesterol value in the experimental group after the intervention. Conclusion: To improve the health of male workers with CVD risk factors in the workplace, sharing health information with their spouses has proven to be more effective than health coaching for only workers. Therefore, it is important to develop strategies to encourage spousal participation when planning workplace health education for changing health-related behaviors.

The purpose of this study is to develop an evaluation model to measure the core competences of actual play workers by exploring what competences are necessary for them to provide quality play. Based on literature review, we selected five core competences : knowledge of play, program development, understanding play culture, creativity, and information sharing & applying. In order to achieve the research purpose end, a two-round Delphi survey was conducted on 10 play and education experts. The findings drew scholarly consensus on the competences of play workers to have and proposed basic data by developing competences evaluation model to measure them. Each of the key competences has three sub-conpetences, each of which included two behavior elements. Furthermore, this study presented future research directions so that play can be voluntarily planned and supported in a social and cultural context.

This study identified the characteristics of fashion rental service users as well as analyzed their purchase decision-making processes. A qualitative investigation was conducted through in-depth interviews with 13 women in their 20s-30s who have experienced renting fashion items due to a high interest in fashion. The results of the study are summarized as follows. The need recognition stage analyzed ventilation by mass media, SNS impact, curiosity, saving shopping time and money, awareness of situational necessity, and creation of various styles. The information search stage analyzed how users obtained information from 2 different sources of nonmarketer-dominated sources and marketer-dominated sources. The pre-purchase stage analyzed the evaluation of alternatives in which study participants used 2 evaluation criteria for fashion rental services and fashion rental items. The purchase stage analyzed how participants wait and select desired items (when receiving the notification of rentable items) or select alternative products. The consumption stage examined the usage frequency and usage method. The study divided the post-consumption evaluation stage into 2 categories for evaluation: personal feelings and service. The post-consumption behavior stage analyzed how participants displayed WOM, eWOM and purchase rental product behavior. Clothing shopping orientation of study participants is displayed in 5 dimensions of brand-seeking propensity, individuality-seeking propensity, economic efficiency-seeking propensity, rationality-seeking propensity, and pleasure-seeking propensity. This study identified three main characteristics in the study participants: interest in the fashion, favorable attitude toward used fashion items, consciousness of others.

Cloud computing has been gaining popularity over decades, and container, a technology that is primarily used in cloud native applications, is also drawing attention. Although container technologies are lighter and more capable than conventional VMs, there are several security threats, such as sharing kernels with host systems or uploading/downloading images from the image registry. one of which can refer to the integrity of container images. In addition, runtime security while the container application is running is very important, and monitoring the behavior of the container application at runtime can help detect abnormal behavior occurring in the container. Therefore, in this paper, first, we implement a signing checker that automatically checks the signature of an image based on the existing Docker Content Trust (DCT) technology to ensure the integrity of the container image. Next, based on falco, an open source project of Cloud Native Computing Foundation(CNCF), we introduce newly created image for the convenience of existing falco image, and propose implementation of docker-compose and package configuration that easily builds a monitoring system.

The major characteristic of open source software (OSS) is innovativeness. Innovativeness stems from the process of sharing and solving technical problems. This study analyzes the impact of voluntary participation and collaboration of OSS developers on sustained participation in the community based on organizational citizenship behavior and social capital theories. Based on Bolino et al. (2002) and Wasko and Faraj (2005), a research model and hypotheses are developed. A total of 152 OSS developers participated in the survey. The hypotheses are tested by LISREL modeling. The results of analysis show that royalty, social participation, and advocacy participation enhance or positively influence social capital. In addition, reciprocity and shared vision reinforce intention of sustained knowledge contribution. However, the result shows a statistically insignificant relationship between social participation and shared vision and between cohesiveness and intention of sustained knowledge contribution.

The development of computer-based information technology has led to the quantitative and qualitative growth of social media which have two sides; a positive one such as the generation and sharing of information and a negative one which includes cyber plagiarism and cyber bullying. This study seeks to understand which factors can lead to cyber plagiarism, which is the most prevalent form of unethical cyber behavior. We expected that the intrinsic and extrinsic motivations for using social media would have different effects on unethical cyber intention and that this relation between motivation and cyber unethical behavior would be moderated by the subjective norm. In order to obtain a better understanding of the relationships among the individual motivation, unethical cyber intention, and cyber plagiarism, information was obtained from 564 social media users. The respondents provided details of their experiences and attitudes regarding social media usage behavior and unethical cyber behavior. The results confirmed that extrinsic motivation significantly increases unethical intention and further leads to high levels of cyber plagiarism. The subjective norm plays a moderating role in the relationships between extrinsic motivation and unethical cyber intention. Based on the results, the theoretical and practical implications of the research findings are discussed, and recommendations for future research are provided.
