본 논문은 전문가들을 대상으로 디지털위험을 관리하는 조직에 대한 신뢰가 위험지각과 위험관리 인식에 미치는 영향을 규명하였다. 주요결과를 보면, 첫째, 전문가들이 디지털위험을 관리하는 조직인 정부, 관련 과학자그룹, 언론, 시민단체, 기업에 대한 신뢰가 높을수록 위험지각은 상대적으로 낮아지는 것으로 나타났다. 둘째, 한국사회 내에 존재하는 다양한 영역의 전문가들이 디지털위험을 관리하는 조직에 대해 높은 신뢰를 가질수록 관련 위험에 대한 관리가 효율적으로 이루어지고 있다고 인식하는 것으로 나타났다. 셋째, 디지털위험에 대한 위험지각은 위험관리 인식에 통계적으로 유의한 영향을 미치지 못하였다. 이런 결과에 비추어볼 때, 한국사회 내 새로운 위험으로 부각되고 있는 디지털위험을 효과적으로 통제, 예방하기 위해서는 사회 내에 신뢰를 높이고, 신뢰에 기반한 의사결정이 이루어져야 할 것이다.

In smart home environment, certificate based signature technology is being studied by communication with Internet of Things(IoT) device. However, block - chain technology has attracted much attention because of the problems such as single - point error and management overhead of the trust server. Among them, Keyless Signature Infrastructure(KSI) provides integrity by configuring user authentication and global timestamp of distributed server into block chain by using hash-based one-time key. In this paper, we provide confidentiality by applying group key and key management based on multi - solution chain. In addition, we propose a smart home environment that can reduce the storage space by using Extended Merkle Tree and secure and efficient KSI-based authentication and communication with enhanced security strength.

Due to increasing spectrum demand for new wireless devices applications, cooperative spectrum sensing (CSS) paradigm is the most promising solution to alleviate the spectrum shortage problem. However, in the interweave cognitive radio (CR) system, the inherent nature of CSS opens a hole to Byzantine attack, thereby resulting in a significant drop of the CSS security and efficiency. In view of this, a weighted differential sequential single symbol (WD3S) algorithm based on MATLAB platform is developed to accurately identify malicious users (MUs) and benefit useful sensing information from their malicious reports in this paper. In order to achieve this, a dynamic Byzantine attack model is proposed to describe malicious behaviors for MUs in an interweave CR system. On the basis of this, a method of data transmission consistency verification is formulated to evaluate the global decision's correctness and update the trust value (TrV) of secondary users (SUs), thereby accurately identifying MUs. Then, we innovatively reuse malicious sensing information from MUs by the weight allocation scheme. In addition, considering a high spectrum usage of primary network, a sequential and differential reporting way based on a single symbol is also proposed in the process of the sensing information submission. Finally, under various Byzantine attack types, we provide in-depth simulations to demonstrate the efficiency and security of the proposed WD3S.

Purpose: This study aimed to examine the relationships between positive nursing organizational culture, organizational communication satisfaction, and the level of work engagement among nurses working in tertiary hospitals, as well as to identify influencing factors on work engagement. Methods: This study used a descriptive research design. Data were collected from 184 general nurses working in four tertiary hospitals in Seoul using self-report questionnaires from March 13 to 30, 2023. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Scheffé test, Pearson correlation, and hierarchical regression. Results: In the hierarchical regression analysis, the variables that significantly influenced work engagement in Model 1 were marital status (β=.26, p=.002), graduate or higher degree (β=.41, p<.001), more than 1 year and less than 3 years (β=.18, p=.030) and 3 years or more but less than 5 years of clinical experience in present hospital (β=.17, p=.023), and satisfaction (β=.27, p=.002) and moderate satisfaction with pay (β=.18, p=.033). In model 2, adding the subdomains of positive nursing organizational culture and organizational communication satisfaction to the Model 1, the variables that had a significant effect on work engagement were trust-based organizational relationships (β=.50, p<.001) and organizational communication satisfaction (β=.25, p=.005). Conclusion: The results suggest that education level, clinical experience, and satisfaction with pay should be considered to improve nurses' work engagement. In addition, it was identified that organizational relationship based on trust and organizational communication satisfaction are the main influencing factors for improving work engagement.

Purpose: Former research has argued that organizations in distribution channels face several issues to make a better team-based system. The purpose of the present research is to measure between employee's job performance and three major issues which disturb a solid team system. Research design, data and methodology: Scant past studies are available to guide for team practitioners which elements should be eliminated to improve team performance. To achieve this goal, the present authors obtained 267 US workers in distribution channels and conducted ANOVA test to measure the relationship between three team issues (Free-rider, Trust, and Communication) and job performance. Results: Our statistical findings clearly suggests that there was a statistically recognizable difference at the significance level of probability between the mean value of employees' job performance and three major issues, showing the high degree of job performance can be occurred by eliminating three major team issues. Conclusions: Therefore, the present research concludes that it is necessary that team-based management in the supply chain should focus on removing free-rider issues and also adopt open communication lines to overcome team-building challenges due to communication. Above all else, the ability to increase trust can be enhanced via task delegation and more team members' engagement.

The main propose of this study is to analyze of the Chinese Fisheries Products competitiveness in Korean Market. This study was using a model of working partnerships by James C. Anderson & James A. Narus(1990). That is, Support is found for a number of the hypothesized construct relations and in both manufacture firm and distributor firm model, for the respecification of cooperation as an antecedent rather than a consequence of trust. This study was able to apply this model's intention for the relationship between Chinese fisheries products exporter and Korean importer, because I thought that competitiveness of trade market was based on relationship between the two countries traders. The results of this study are summarized as follows. As the above result, the several hypothesized correlation among the factors were significant. These results was tried to apply the competitiveness degree index as main factors among the countries, The method of measuring competitiveness .degree index was [(outcome + influence + communication + coopration + trust + satisfaction) - conflict, In result, China was 21.5583, USA was 20.2667, East Asia was 18.79126, EU was 18.4723, Russia was 16.3858.

Purpose: One of the characteristics of service companies such as foodservice franchise is that it is easy to imitate, so many brands can imitate the menu that is popular with consumers. Therefore, foodservice franchise company should develop a brand that customers can identify from other brands in order differentiate it from its competitors. In order make the foodservice franchise company identifiable from other brands, it is possible through communication with customers. Therefore, this study proposes a new research model to analyze customer loyalty through online advertising and online word of mouth trust and immersion. Online was provided to customers through a mixture of advertisements and word of mouth, but previous studies have only considered online advertisements or online word of mouth. In addition, we want to verify the difference according to gender, which is an important variable in researching the online information processing behavior of customers. Research design, data, and methodology: The questionnaire of this study was surveyed on 20 years of age or older who have visited the restaurant franchise store within the last 3 months among the foodservice franchise companies operating SNS. During the survey period, 400 surveys were surveyed for a total of 20 days from April 1 to April 20, 2020. Result: The research results are as follows. First, in this study, the effect of online advertisement and online word of mouth on trust and immersion was studied. Second, this study verified the social influence theory in online advertising and online word of mouth. Third, the effect of online advertising and online word of mouth on loyalty according to gender was verified. Fourth, compared to existing advertisements, online advertisements are suitable for marketing by foodservice franchise companies because they can interact with consumers, modify advertisements immediately, execute extensive advertisements at low cost, segment the market, and measure advertisement effectiveness. The recent online expansion has been expanded to mobile-based, allowing foodservice franchisees to provide new communication services such as SMS (Short Message Service), multimedia messaging services, and location-based services. Fifth, a foodservice franchise company can increase brand awareness through online marketing or induce the use of offline stores. Sixth, franchisor can grow into a sustainable company only when they use resources efficiently. Conclusions: Trust is important in foodservice franchise information. This trust has a significant impact on customer commitment and loyalty.

신뢰와 고객충성도의 관계에 대한 선행연구들에 따르면, 현지 진출한 다국적기업들은 현지 소비자들의 신뢰를 얻음으로써 고객충성도를 강화할 수 있다. 본 연구는 한국에 진출한 다국적기업의 제품특성, 제품관련 서비스 커뮤니케이션, 지각된 가격공정성 등이 다국적기업 제품신뢰에 어떤 영향을 미치는지를 분석함으로써 다국적기업 제품신뢰의 선행요인을 탐색하고자 하였다. 또한 글로벌 기업시민주의가 전 세계적으로 점점 요구되고 있는 현실에서 현지에 진출한 다국적기업이 기업시민으로서 사회적 책임을 다한다는 인식을 확보한다면 제품에 대한 신뢰형성에도 기여할 것으로 본다. 이러한 맥락에서 글로벌 기업시민주의가 신뢰와 그 선행요인간 관계를 조절할 것인지에 대한 분석을 함께 하였다. 조절 회귀분석을 통하여 가설을 검증한 결과, 다국적기업 제품신뢰에 통계적으로 유의한 영향을 미치는 선행요인은 제품과 서비스 커뮤니케이션으로 나타났다. 제품관련 서비스 커뮤니케이션이 신뢰에 더 큰 영향력 요인이었다. 현지 소비자들은 다국적기업이 제공한 제품과 서비스에 대하여 신뢰를 하고 있다고 판단되므로 다국적기업들은 제품과 서비스로 이루어진 기업의 제품전략과 신뢰를 연계하고 소비자의 신뢰를 증진함으로써 고객충성도를 강화할 수 있도록 전략을 수립하여야 한다. 한편, 가격공정성 지각 가설은 기각되었으나 가격공정성 지각과 신뢰와의 관계에 글로벌 기업시민주의의 조절효과가 통계적으로 유의하게 나타났다. 이는 지각된 가격공정성은 다국적기업의 기업시민주의활동을 통해 선량한 기업으로 소비자에게 인지됨으로써 그 기업 제품에 대한 신뢰를 확보할 수 있음을 제시하는 것이다.
