This study examined the validity and the reliability of the perceived elderly stigma scale. Moreover, we investigated the relationships between the perceived elderly stigma and demographic factors (age, gender, education, and income). The initial scale consisted of 5 factors (ability, personality, appearance, authoritarian dependency, and child-obsession) and 28 items. In order to test the validity and the reliability of the scale, this study conducted a survey with 693 adults aged 18 to 65. Based on the confirmatory factor analysis (CFA), the scale was modified to 5 factors (ability, personality, appearance, authoritarian dependency, and child-obsession) and 15 items and its convergent validity and discriminant validity were confirmed. In terms of the relationships between the perceived elderly stigma and demographic factors, age had a negative relationship with the "ability" stigma, and education was a negatively associated with the "appearance" stigma.

This study analyzes educational panel on the relationship between college life and job satisfaction of women college graduates. Higher college satisfaction increases job satisfaction of women workers with college degrees. Job training programs increase job satisfaction. However, job satisfaction relative to her skills and competency becomes lower when they complete a number of job training programs. Moreover, English education and job training programs exert positive influences over the effects of college satisfaction on job satisfaction of women workers with college degrees. Thus, although there are conflicting aspects, job training programs have potentials to contribute to the job satisfaction. The results of the study suggest that college life is closely related with their job experiences. However, Korean society neglects the importance of college relative to four-year university. Thus, Korean society exerts efforts toward enhancing the educational quality of college education.

The aim of this study is to shed light on factors that influence securing of university research grants. For this purpose, this study emphasizes the role of management capability of industry-university cooperation foundation in securing research grants. We analyze whether the potential capabilities influence research grants using panel data from 194 universities during 2016 to 2018. The results obtained from the Driscoll & Kraay standard errors (DKSE) indicate that a number of variables including the portion of industry-university collaboration professors, academic performance of professors, and the number of paid researchers are positively associated with the amount of external research grant approved. However, the percentage of employees employed for less than two years is negatively related with securing external research grants. Once the dependent variable is measured by the total university research grants, the negative coefficient of employees with short-term career disappears. Instead, the percentage of employees who are in charge of research planning and management and the total number of employees involved in industry-university collaboration foundations are negatively related with the total university research grant amounts.

In this paper, we propose two-way authentication protocol between unmanned systems in tactical wireless networks in which long distance communications are not guaranteed due to a poor channel conditions. It is assumed that every unmanned systems have same random data set before they put into combat. The proposed protocol generates authentication code(AC) using random data that causes hash collision. The requester for authentication encrypts the materials such as their identifier, time-stamp, authentication code with the secret key. After then the requester transmits the encrypted message to the receiver. The receiver authenticates the requester by verifying the authentication code included in the request message. The performance analysis of the proposed protocol shows that it guarantees the security for various attack scenarios and efficiency in terms of communication overhead and computational cost. Furthermore, we analyzed the effect of the parameter values of the proposed protocol on the performance and suggest appropriate parameter value selection guide according to the level of security requirement.

After independence in 1945, the South Korean economy rose steadily from a developing country to a developed country while, after independence in 1960, Nigeria is still a developing country with poverty on the increase, despite its large amount of natural resources. This research seeks to find a viable solution to this issue while studying the relationship that exist amongst Economic Development Plans (EDPs), National Innovation System (NIS) and economic development in Korea. The methodology used herein is a mixture of a systematic literature review and a semi-structured interview. The results of this study show that EDPs are essential to the enhancement of communication, and the flow of knowledge and innovation of the NIS. Furthermore, our result shows that the efficiency of the NIS is relevant to drive economic growth and development. Therefore, based on our analysis of the current situation in Nigeria and the development trajectory of Korea, we developed, introduced and recommended a theoretical framework called the "Multiple skipping" development trajectory as a model for development in Nigeria.

The tactical mobile ad-hoc network(MANET) consists of distributed autonomous networks between individual ground nodes, which is effective in terms of network survivability and flexibility. However, due to constraints such as limited power, terrain, and mobility, frequent link disconnection and shadow area may occur in communication. On the other hand, the satellite network has the advantage of providing a wide-area wireless link overcoming terrain and mobility, but has limited bandwidth and high-latency characteristic. In the future battlefield, an integrated network architecture for interworking multi-layer networks through a heterogeneous network gateway (HNG) is required to overcome the limitations of the existing individual networks and increase reliability and efficiency of communication. In this paper, we propose a new HNG architecture and detailed algorithm that integrates satellite network and the tactical MANET and enables reliable data transfer based on flow characteristics of traffic. The simulations validated the proposed architecture using Riverbed Modeler, a network-level simulator.

The purpose of this study examines the effects of corporate CSR on corporate image, customer satisfaction, and customer citizenship behavior in order to provide implications for CSR. To verify hypotheses, we conducted a questionnaire survey on university students using Apple, Sony, Sharp, and Kyocera mobile phones, and used structural equation model analysis for 294 units. As a result, four factors, economic responsibility, legal responsibility, ethical responsibility and philanthropic responsibility were derived from corporate social responsibility, and all three factors except for ethical responsibility factors were proved to have a positive effect on corporate image. In addition, corporate image has a positive effect on customer satisfaction and customer civic behavior. As an implication, Japanese companies will need to take a systematic approach to CSR to help them understand their CSR and improve the level of CSR they can sympathize with.

This paper is designed to address the extent of impacts that religious musicals may have upon on audience in contrast to the mainstream musicals by exploring choice attributes of Christian musicals, which are based on the stories of the Bible. Through empirical analysis, the paper shows that there is positive correlation between choice attributes and viewing satisfaction, while explaining choice attributes' impact on behavioral intention of audience, typically in word-or-mouth intention. It further shows that choice attribute of Christian musicals have direct positive impacts on both of behavioral and word-of-mouth intentions, which revisit intention is positively related to its reputation and the performance place. This study's significance lies in the use of Christian musicals to explore the complex interactions between choice attributes and audiences' behavioral intentions afterwards. However, it will also further benefit if future research include further mediating, control variable, including non-Christians.

This study was conducted to identify the use motivations of AI speaker and examine the characteristics of AI speaker users. Based on the uses and gratifications theory, The study results show that the user motivations of AI speaker are four dimensional, namely escaping from daily problems and maintaining social relationships, information acquisition and learning, entertainment and relaxation and pursuit of practicability. The main AI speaker users are in their 30s, and they are innovative to actively use AI speakers for entertainment purposes such as listening to music. The four sub-dimensions differed as we compared them with user characteristics. Specifically, the motivation for escaping from daily problems and maintaining social relationships varied with gender and age. Moreover, age and informativeness were identified to have an influence on the motivations of information acquisition and learning and entertainment and relaxation. In sum, this research provides practical implications into how to strategically create contents and services for AI speakers.
