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.

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.

Objective: To report the improvements with Korean medicine-based integrative cancer therapies on adverse effects of adjuvant chemotherapy in non-small cell lung cancer patients. Method: There were two patients complained cough, rhinorrhea, numbness, general weakness, nausea and dyspepsia after chemotherapy. They got treated centered on Korean medicine including herbal medicine, acupuncture, electro-acupuncture, pharmacopuncture, moxibustion, hand and foot bath. They were also treated Western immunotherapies like Thymosin at regular intervals. The symptoms were measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 for Palliative Care(EORTC QLQ C-15 PAL) and their subjective assessments. Results: Their chief complaints were relieved and their quality of life scores was improved even though they have been receiving chemotherapy continuously. Conclusion: These cases revealed a possibility that Korean medicine-based integrative cancer therapies could improve some symptoms after chemotherapy in non-small cell lung cancer.

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.

본 연구에서는 타원궤도상에서 위성의 편대비행을 유지하기 위하여 필요한 포기조건을 결정하고자 한다. 타원궤도일 경우 Hill 방정식으로는 위성간의 상대운동을 기술할 수 없기 때문에, Hill 방정식의 초기조건에 비선형성과 이심률에 대한 보정을 하여 얻은 새로운 운동방정식을 사용했다. 편대비행에서 상대적 거리를 유지하기 위하여 주위성과 부위성의 평균각속도를 일치시키는 구속조건을 이용했다. 이 구속조건은 J2 섭동항을 고려한 것이므로, 이 구속조건을 만족하는 편대비행의 초기조건은 타원궤도에서의 위성편대비행을 유지하는데 잘 적용될 수 있다. 타원궤도에서의 상대운동방정식 초기조건에 J2 섭동을 고려한 구속조건을 적용할 때, 이심률이 0.05 이하이고 위성간의 상대거리가 0.5km 정도인 경우만이 주기적으로 일정하게 간격이 유지되는 결과를 얻을 수 있다. 따라서 이심률이 크지 않은 타원궤도에서는 평균각속도 일치의 구속조건을 사용하여 위성간의 상대거리를 유지할 수 있었다. 이러한 결과를 이용하여 타원궤도에서의 위성편대비행을 위한 효율적인 초기조건을 제공할 수 있고, 위성편대비행의 운용에 있어서 비용을 절감할 수 있는 방법을 제시할 수 있다.
