In this paper we suggest a dynamic quota allocation mechansim for B-ISDN(Broadband Integrated Services Digital Network) subscriber networks. The quota adaptation decision based on the number of cells in the transmission queue is made distributively by each node in the ring network. This mechanism provides both fairness and efficiency for it enables each node to adapt its quota under asymmetric traffic condition. The simulation results show that substantial improvements in access delay time and throughput can be achieved with this algorithm.

약가 인하 처분은 국민건강보험법령에서 정하는 직권 조정 사유가 있는 경우에 한하여 행정절차법이나 국민건강보험법령에서 정하는 행정 절차에 따라 내려진다. 그런데 약사법상 허가특허연계제도에 따라 후발의약품의 판매 시점이 달라짐으로 인하여 또는 약가 인하 처분에 대한 집행정지 신청의 인용 또는 기각 결정, 행정절차법이나 국민건강보험법령에 따른 행정 절차 진행 기간에 따라 약가 인하의 효력 발생하는 시점이 늦어지거나 빨라질 수 있다. 약가 인하의 효력 발생 시점이 늦추어지면 그만큼 제약회사가 이익을 얻고 반대로 국민건강보험의 보험자가 손실을 입는다. 반대로 약가 인하의 효력 발생 시점이 빨라지면 그만큼 국민건강보험의 보험자가 이익을 얻고 반대로 제약회사는 손실을 입는다. 그런데 그 이익이나 손실이 사후적으로 볼 때 부당하다고 평가될 수 있는 경우가 있다. 약가 인하 처분 사유는 동일한데 약가 인하의 효력이 발생할 때까지의 절차에서 발생하는 사정으로 인하여 제약회사나 국민건강보험의 보험자가 망외의 이익(windfall)을 얻고 그로 인하여 반사적으로 국민건강보험의 보험자나 제약회사가 손실을 입는다면 부당하다. 본고에서는 그 문제를 분석하고 이에 대한 해결 방안을 모색한다.

Objectively, the purpose of this study aims to re-confirm and analyze the relationship between variables through direct relationships and mediation (i.e., career optimism (CO), organizational fairness (OF), organizational entrepreneurship commitment (OEC) on employee engagement). This study also addresses whether career optimism provides a strong-impact if it mediates other antecedent variables on employee engagement. Therefore, to test and prove this, we made observations on 200 samples comprising lecturers in Indonesia. The data collection method uses a survey both offline and online. Through the PLS-SEM approach, the statistical testing demonstration states that all hypotheses, either through direct relationship or mediation, are proven to have a positive and significant effect. Career optimism has also proven to be a substantial and positive contribution to testing employee engagement as a mediating variable. The results of seven hypothesis testing in our study confirm that the broaden-built theory and organizational theory are closely related. Therefore, this study positively contributes to human resource management's science to balance the psychological and organizational aspects. In this study, we also add that consistency and a positive attitude in a career trigger a person's career optimization in a better and more positive direction, especially for career-path and employee engagement.

This study conducts an in-depth analysis of user reviews from three leading metaverse platforms - Minecraft, Roblox, and Zepeto - using advanced topic modeling techniques to uncover key factors for business success. By examining a substantial dataset of user feedback, we identified and categorized the main themes and concerns expressed by users. Our analysis revealed that common issues across all platforms include technical functionality problems, user engagement and interest, payment concerns, and connection difficulties. Specifically, Minecraft users highlighted the importance of adventure and creativity, Roblox users expressed significant concerns about security and fraud, and Zepeto users focused heavily on the fairness of the in-game economy. The findings suggest that for metaverse platforms to achieve sustained success, they must prioritize the resolution of technical issues, enhance features that foster user engagement, ensure reliable connectivity, and address platform-specific concerns such as security for Roblox and payment fairness for Zepeto. These insights provide valuable guidance for developers and business strategists, emphasizing the need for robust technical infrastructure, engaging and diverse content, seamless user access, and transparent and fair economic systems. By addressing these key areas, metaverse platforms can improve user satisfaction, build a loyal user base, and secure long-term success in an increasingly competitive market.

The transfer pricing mechanism is a tool commonly used to transfer the tax base from countries with high taxation in countries with low taxation. In many countries, this financial operations generate significant tax revenue losses. In an attempt to limit tax revenue losses, many public authorities have introduced regulations on transfer pricing, but the effectiveness of these rules has proved limited, and they contributed to the increasing complexity of tax laws and to the appearance of additional costs for companies. Historically, transfer pricing (TP) was not a substantial issue in Mongolia. The tax legislation contains basic TP rules, but there is limited guidance and enforcement in practice. At the moment, Mongolian tax authorities are not conducting specific transfer pricing audits. Nevertheless, tax authorities are starting to pay more attention to transactions between related parties and potential transfer pricing adjustments. This study examines a transfer pricing regulations of Mongolia.

Purpose: This study was conducted to verify the effects of self-esteem and critical thinking disposition on dental laboratory technology students' field practice stress. Methods: The subjects of the study were 198 dental laboratory technology students with clinical practice experience located in Gyeongsangbuk-do and Gyeongsangnam-do. The collected data were analyzed by t-test, ANOVA, correlation analysis, and linear regression analysis using IBM SPSS Statistics ver. 22.0 (IBM). Results: The average self-esteem, critical thinking disposition, and field practice stress scores were 3.76, 3.50, and 2.40, respectively. There was a significant correlation between self-esteem, critical thinking disposition, and field practice stress. It was found that the higher the self-esteem, the lower was the field practice stress. On the contrary, among the sub-items of critical thinking disposition, when intellectual fairness increased, the field practice stress decreased; however, when healthy skepticism increased, the field practice stress increased. Conclusion: Self-esteem and critical thinking disposition were both found to have a substantial effect on field practice stress. Therefore, various educational programs need to increase self-esteem and cultivate critical thinking skills for a successful field practice and field practice stress relief of laboratory technology students.

Recently, there is a substantial interest in implementing Business Process Management System(BPMS) among enterprises with the purpose of business process innovation. BPMS redesigns and coordinates business processes in terms of both automated steps and human involvement in order to maximize the value of both involved people and systems. The reason why BPMS is getting attention from top managers is that it has the possibility to optimize the business processes by cycling the process of modeling, execution, monitoring, evaluation, and redesigning work processes. Thus, it has created high expectations about not only productivity improvement but also business process innovation. However. having an innovative nature, which is used for process innovation, BPMS implementation has great potential to stir up employee resistance. The analysis and the discussion about the prevention of the resistance against IS(Information Systems) is important because IS change the way people work and also alter the power structure within the organization, in general. The purpose of this study is to investigate factors that have an impact on the effective adoption of BPMS at the enterprise level. To find out these factors, this study considers two characteristics of BPMS: First. BPMS shares some characteristics with other enterprise-wide IS such as ERP. Second, it has special BPMS-specific characteristics. Due to the lack of previous research on BPMS adoption, interviews were carried out with IT-consultants and CIOs who conducted BPMS projects previously to find out BPMS-specific features that would make BPMS unique when compared to other enterprise-wide IS. As a result, the monitoring function was chosen as the main BPMS-specific factor. Thus, this paper reviewed studies both on enterprise-wide IS adoptions, which applied Technology Acceptance Model (TAM) and secondly on computer based monitoring to find out factors that would influence the employees' perception on the monitoring function of BPMS. Based on the literature review, the study suggested three factors that would have an impact on the employee's perception of the monitoring function: fairness of enterprise evaluation system, fairness of the boss, and self-efficacy of their work. Three factors that would impact the enterprise-wide IS adoption were also set: the shared belief in the benefit of BPMS, training, and communication. Then, these factors were integrated with TAM. Structural equation modeling was used to test hypotheses, out factors that would impact the employees' perception on the monitoring function of BPMS. Based on the literature review the study suggested three factors that would have an impact on the employee's perception of the monitoring function: fairness of enterprise evaluation system, fairness of the boss, and self-efficacy of their work. Three factors that would impact the enterprise-wide IS adoption were also set: the shared belief in the benefit of BPMS, training, and communication. Then, these factors were integrated with TAM. Structural equation modeling was used to test hypotheses. The data analysis results showed that two among three monitoring function related factors - enterprise evaluation system and fairness of the boss - were significant. This implies that employees would worry less about the BPMS implementation as long as they perceive the monitoring results will be used fairly for their performance evaluation. However, employees' high self-efficacy on their job was not a significant factor in their perception of the usefulness of BPMS. This is related to cases that showed employees resisted against the information systems because they automated their works (Markus, 1983). One specific case was an electronic company, where the accounting department workers were requested to redefine their job because their working processes were automated due to BPMS implementation.
