  • Three-dimensional (3D) reconstruction of cone-beam computed tomography (CBCT) scans appears to be a valuable method for assessing pulp canal configuration. The aim of this report is to describe endodontic treatment of a mandibular second premolar with aberrant pulp canal morphology detected by CBCT and confirmed by 3D modeling. An accessory canal was suspected during endodontic treatment of the mandibular left second premolar in a 21 year old woman with a chief complaint of pulsating pain. Axial cross-sectional CBCT scans revealed that the pulp canal divided into mesiobuccal, lingual, and buccal canals in the middle third and ended as four separate foramina. 3D modeling confirmed the anomalous configuration of the fused root with a deep lingual groove. Endodontic treatment of the tooth was completed in two appointments. The root canals were obturated using lateral compaction of gutta-percha and root canal sealer. The tooth remained asymptomatic and did not develop periapical pathology until 12 months postoperatively. CBCT and 3D modeling enable preoperative evaluation of aberrant root canal systems and facilitate endodontic treatment.

  • This article analyzes factors affecting the application of strategic management accounting in different enterprises in Vietnam's consumer goods industry, providing more empirical evidence on factors affecting the application of strategic management accounting. The research method used a questionnaire survey of managers at all levels, chief accountants, and accountants from 72 consumer goods enterprises in Vietnam. The survey results collected 290 questionnaires, however, due to invalid questionnaires with many blank cells, 284 questionnaires were finally selected. Quantitative research was carried out with SPSS 25 software. Research results show that 6 factors have a positive influence on the application of strategic management accounting including awareness of the business market, business strategy, technology, corporate culture, qualification of management accountants, decentralization of management, in which technology has the strongest influence on the application of strategic management accounting in consumer goods enterprises in Vietnam. The standardized Beta coefficient extracted from the multiple linear regression equation reveals that the technology factor has a high standardized Beta coefficient (0.176) compared to other factors. Based on the research results, the author has proposed recommendations to improve the ability of consumer goods businesses to successfully apply strategic management accounting techniques, thereby contributing to improving competitiveness and performance of consumer goods enterprises.

  • A novel distributed compress-and-forward (CF) system based on multi-relay network is presented. In this system, as the direct link between the source and destination is invalid due to some reasons, such as the limited power, special working environment, or even economic factors, relays are employed to receive analog signals and carry on distributed compressed encoding. Subsequently, the digital signals are transmitted to the destination via wireless channel. Moreover, a theoretical analysis for the system is provided by utilizing the Chief Executive Officer (CEO) theory and Shannon channel capacity theory, and the rate-distortion function as well as the connection between the transmission rate and the channel capacity are constructed. In addition, an optimal signal-to-noise ratio (SNR) -based power allocation method is proposed to maximize the quantization SNR under the limited total power. Simulation result shows that the proposed CF system outperforms the amplify-and-forward (AF) system versus the SNR performance.

  • The purpose of this research is to examine the effect of Servant Leadership and Business Transformation on Corporate Competitiveness and Corporate Sustainability. In this research, Service Innovation is the mediating element. The sample of this study was made up of all ship leaders in all crossings of PT ASDP Indonesia Ferry (Persero), which consisted of 150 Commanders or Chief Commanders (Mualim I). The location of the research is the Vessel PT. ASDP Indonesia Ferry (Persero) is used on all crossings of the company. It is a survey research using questionnaires given to 150 respondents. The validity and reliability were checked using Pearson correlation and Cronbach's Alpha. The analysis used the WarpPLS statistical method and WarpPLS software. The results from this research show that the increased Servant Leadership will improve Service Innovation. Business Transformation developed by PT ASDP has not been able to improve Service Innovation. To our knowledge, there is no study on the concept of comprehensive competitiveness and sustainability involving Servant Leadership, Business Transformation, and Service Innovation in an integrated and simultaneous manner. Therefore, the novelty of this research is the development of concepts or models of Corporate Competitiveness and Corporate Sustainability Theory through Servant Leadership, Business Transformation, and Service Innovation.

  • Through 'The Renewable Energy 3020 Implementation Plan' for carbon neutrality, the government promised to raise the proportion of renewable energy generation to 20% and renewable energy installation capacity to 63.8% by 2030. Therefore, we plan to test a 5.5 MW offshore wind turbine near Maldo, Gunsan. In this project, we measure the level of public acceptance and perform ordinary least squares (OLS) regression analysis to show the determinants of public acceptance. The regression results are as followed. First, it is judged that the closer the distance to the offshore wind turbine, the more the economic effects considered by residents. Second, especially in Maldo, the experience of being discriminated from the Saemangeum project, is understood to have caused distrust in the surrounding fishing villages chief/Fisheries Cooperatives, converted into a local community effect. Finally, the policy implications are as follows. First, a bottom-up problem-solving method is required to improve public acceptance, based on the Living Lab. Second, the island community may be indifferent to the briefings or forums of outsiders. Therefore, a gradual approach is required through (in)formal channels based on reliability from a long-term perspective with nearby universities and research institutes using SamsØ Energy Academy.

  • The mourning attire worn by the Sangju (Chief Mourner) during Confucian funeral rituals is known as Gulgeonjebok. It is comprised of Gulgeon, Sujil, and Hyogeon on the head, and Jungui underneath. On top of the Jungui, the ceremonial garments called Choeui are worn, along with Choesang. Yojil and Gyodae are then tied around the waist. Mahye and Hangieon are worn on the feet, and a walking stick made of bamboo, paulownia, or willow is carried. A needlework master, Choe Onsun, who was designated as a Holder of Intangible Cultural Property of Jeollabuk-do on November 27, 1998, is recognized for her efforts in restoring and recreating the forgotten Gulgeonjebok. Thanks to her endeavors, the period, regional, and cultural characteristics of Gulgeonjebok in the Jeolla Province have been preserved. This study aims to examine and reproduce characteristic items of Gulgeonjeboks handed down by a needlework master, Choe, by conducting an empirical study on the dimensions and schematization of the Gulgeon, the method of cutting, and the sewing process. The empirical research on Gulgeojebok is expected to further enhance traditional sewing skills. It will also serve as a foundation for deepening the level of research on traditional dress and sharing traditional cultural heritage.

  • The initial conditions that generate bounded motion in eccentric reference orbit are determined for satellite formation flying. Because Hill's equations cannot describe the relative motion between two satellites in eccentric orbit, a new relative dynamics utilizing the nonlinearity and eccentricity correction for Hill's initial conditions is implemented. The constraint that matches angular rates of chief and deputy satellites is used to obtain the bounded motion between them. The constraint can be applied to satellite formation motions in eccentric orbit, since it implicates J2 perturbation due to the central body's aspherical gravitational forces. The periodic bounded motions are analyzed for the orbit with the eccentricity of less than 0.05 and about 0.5 km relative distance between chief and deputy satellites. It is mainly illustrated that the satellite formations in small eccentric orbits can have hounded motions; consequently, the formation can be kept by matching angular rates of the satellites. These results demonstrate an useful method that reduces the cost for operating satellites by providing effective initial conditions for satellite formation flying in eccentric orbit.
