This Study aims to propose a new information security governance model design method for streamlining security governance at national strategic level. The research method of this study is to diagnose our operational experience and to derive a new model design method. In the meantime, national information security activities were perceived to be focused on knowledge transfer, and motivation of activities and securing of executive power were weak. As a result, security blind spots and frequent occurrence of large security incidents have become unresolved challenges. National cyber security governance should be grouped together as a whole systematically from the upper policy to the lower level of performance under the responsibility of the national leader. Based on this approach, this study presented the comprehensive framework of Korean security governance model and embodied it into four architectural designs such as vision, goal, process, and performance, thus deriving the foundation for future national governance model design. Further research is needed to diagnose problems in life cycle flow, security policies based on environmental changes, and new frameworks in which all subjects participate.

Given the increasing of adoption of use of Mobile Wireless Technology(MWT), this study aims at investigating the key influencing determinants of individuals' MWT adoption and use. Based on the Technology Acceptance Model(TAM), the research model proposed new constructs and casual relations, Perceived Safety(PS), Perceived Costs(PC), Company's Willingness to Fund(CWF), and Experience(E) as a moderator. The model was tested using Structural Equation Modeling(SEM) using AMOS 5.0 analysis on the sample collected from 387 MBA and Executive MBA students of several domestic and foreign universities. The results show that not only the variables, except Perceived Usefulness, in the original TAM model, but also new variables in the research model had a significant influence on other variables. The implications of the findings suggest a new theoretical framework for future IS/IT research and offers suggestions that the developers of MWT should consider regarding the technology

As the MZ generation, who values work-life balance, became a member of the organization, leader-oriented leadership centered on goal achievement and company profit made it difficult to achieve good results in the organization in the mid-to long-term. The company must strengthen the leadership that can be helpful for the self-leadership where the members of the organization move on their own and the organizational culture that enhances the employees' job satisfaction and organizational commitment. Therefore, this study analyzed the effect of the team leader's servant leadership on the team member's self-leadership and organizational effectiveness. In addition, it was studied whether the executive officer's emotional leadership interacted with the team leader's servant leadership and had a moderating effect on the team member's self-leadership. Also, the difference in path coefficient between the MZ generation and the non-MZ generation was verified. To this end, the research model was statistically verified using the PLS (Partial Least Square) structural equation. A survey was collected from 357 team members among office workers online. As a result of the analysis, the team leader's servant leadership had a significant effect on organizational effectiveness and team member's self-leadership. Also, in the relationship between the team leader's servant leadership and the team member's self-leadership, the emotional leadership of the executive officer had a positive (+) moderating effect. The MZ generation differed from the non-MZ generation in the path where the team leader's servant leadership positively affected the self-leadership of the team member and the path where the team leader's self-leadership had a mediating effect between the team leader's servant leadership and organizational effectiveness. The results of this study will suggest various theoretical and practical implications so that executive officers, team leaders, and team members within the company can develop leadership that increases organizational effectiveness in their respective positions.

A MOM-based algorithm (MOMA) has been developed for moving force identification from dynamic responses of bridge in the companion paper. This paper further evaluates and investigates the properties of the developed MOMA by experiment in laboratory. A simply supported bridge model and a few vehicle models were designed and constructed in laboratory. A series of experiments have then been conducted for moving force identification. The bending moment and acceleration responses at several measurement stations of the bridge model are simultaneously measured when the model vehicle moves across the bridge deck at different speeds. In order to compare with the existing time domain method (TDM), the best method for moving force identification to date, a carefully comparative study scheme was planned and conducted, which includes considering the effect of a few main parameters, such as basis function terms, mode number involved in the identification calculation, measurement stations, executive CPU time, Nyquist fraction of digital filter, and two different solutions to the ill-posed system equation of moving force identification. It was observed that the MOMA has many good properties same as the TDM, but its CPU execution time is just less than one tenth of the TDM, which indicates an achievement in which the MOMA can be used directly for real-time analysis of moving force identification in field.

Objectives: The aim of this study was to investigate the significance of associations between knowledge, professional ethics, institutional support, perceptions regarding HIV/AIDS, and HIV/AIDS-related stigma among health workers in West Sumatra, Indonesia. Methods: We conducted a cross-sectional study involving health workers at public hospitals and health centers in West Sumatra in June 2022. The Health Care Provider HIV/AIDS Stigma Scale was employed to assess the stigma associated with HIV/AIDS. To estimate and evaluate the model's ability to explain the proposed constructs, we utilized the standardized partial least squares structural equation model (PLS-SEM). Results: In total, 283 individuals participated in this study (average age, 39 years). The majority were female (91.2%), nearly half were nurses (49.5%), and 59.4% had been working for more than 10 years. The study revealed that HIV/AIDS-related stigma persisted among health workers. The PLS-SEM results indicated that all latent variables had variance inflation factors below 5, confirming that they could be retained in the model. Knowledge and professional ethics significantly contributed to human immunodeficiency virus (HIV)-related stigma, with an effect size (f²) of 0.15 or greater. In contrast, perceived and institutional support had a smaller impact on HIV-related stigma, with an effect size (f²) of at least 0.02. The R² value for health worker stigma was 0.408, suggesting that knowledge, professional ethics, institutional support, and perceived support collectively explain 40.8% of the variance in stigma. Conclusions: Improving health workers' understanding of HIV, fostering professional ethics, and strengthening institutional support are essential for reducing HIV-related stigma in this population.

This paper employs stochastic processing techniques to analyze explosion risks in plant facilities based on explosion return periods. Release probability is calculated using data from the Health and Safety Executive (HSE), along with annual leakage frequency per plant provided by DNV. Ignition probability, derived from various researchers' findings, is then considered to calculate the explosion return period based on the release quantity. The explosion risk is assessed by examining the volume, radius, and blast load of the vapor cloud, taking into account the calculated explosion return period. The reference distance for the design blast load model is determined by comparing and analyzing the vapor cloud radius according to the return period, historical vapor cloud explosion cases, and blast-resistant design guidelines. Utilizing the multi-energy method, the blast load range corresponding to the explosion return period is presented. The proposed return period serves as a standard for the design blast load model, established through a comparative analysis of vapor cloud explosion cases and blast-resistant design guidelines. The outcomes of this study contribute to the development of a performance-based blast-resistant design framework for plant facilities.
