Purpose: Predicting the financial distress distribution of an enterprise is important to warn enterprises about their future. Predicting the possibility of financial distress helps companies have action plans to avoid the possibility of bankruptcy. In this study, the author conducted a forecast of the financial distress distribution of enterprises. Research design, data and methodology: The forecasting method is based on Logit and Discriminant analysis models. The data was collected from companies listed on Vietnam Stock Exchange from 2012 to 2020. In which there are both companies suffer from financial distress and non-financial distress. Results: The forecast analysis results show that the Logistic model has better predictability than the Discriminant analysis model. At the same time, the results also indicate three main factors affecting the financial distress of enterprises at all three research stages: (1) Liquidity, (2) Interest payment, and (3) firm size. In addition, at each stage, the impact of factors on financial distress differs. Conclusions: From the results of this study, the author also made several recommendations to help companies better control company operations to avoid falling into financial distress. Adjustments to current assets, debt, and company expansion considerations are the most important factors for companies.

This study aims to investigate the factors that contribute to the sustainable development of 334 Vietnamese construction and real estate companies listed on the Stock Exchange of Vietnam over a 5-year period from 2016 to 2020. By using regression analysis with the support of STATA software through examining the financial statements, which involves looking into crucial ratios including capital structure, profitability, firm size, accounts receivable management, and tangible assets investment, this study sheds light on whether these accounting indicators could help predict the construction and real estate companies growing potential in the future. Nevertheless, these ratios slightly contribute to the explanation of the change in revenue growth ratio, with a result of 1.6%, indicating that the value relevance of accounting information provides a modest and insignificant effect on investment decisions. This is understandable because the Vietnamese construction and real estate market still has many shortcomings in handling unexpected events, as well as the industry’s peculiarities related to major capital sources from bank loans. Based on this study, governmental authorities and business executives should plan appropriate risk management policies and measures to contribute to the sustainable development of construction and real estate companies.

Black queen cell virus (BQCV), one of the most prevalent viruse, causes the death of queen larvae and pupae. The RNA-dependent RNA polymerases (RdRPs) are central components in the life cycle of RNA viruses that catalyzes the replication of RNA from an RNA template without DNA stage. Inhibition of RdRP gene is importantly significant for application of monoclonal antibody generation as a diagnosis tool for identifying BQCV infection in honey bee..In this study, the presence of BQCV in honey bee samples was confirmed by PCR using BQCV F/R primer set to multiply of 700 bp DNA fragment. For ampification of BQCV Rdrp gene, a primer set attached BamHI/SalI restriction site was designed based on the best homogenization between BQCV RdRP sequences in NCBI, a PCR product containing BQCV RdRP gene with 1576 bp in length was amplified. Furthermore, BQCV RdRP gene will be cloned into pBlueXcm vector for future researches.

This paper introduces omni-directional walking control of a six-legged robot (6LR). The 6LR consists of its body, six legs with four links and four rotational joints. The followings are done for this task. First, the walking gait of the 6LR is chosen. Second, modeling for one leg with four links and four rotational joints of the 6LR is proposed. It is difficult and complex to get the angles of four rotational joints in the case of using inverse kinematics. To solve this problem, differential kinematics algorithm is used to generate omni-directional walking trajectory of a leg based on back-stepping control using Lyapunov stability. Finally, simulation results for walking motion of one leg of the 6LR are shown to prove the effectiveness and applicability of the proposed controller.

OFDMA 기반 다중사용자 시스템에서는 상향링크 피드백 형식으로 기지국에 보고되는 각 사용자의 채널 품질 정보(CQI)를 기반으로 사용자를 선택한다. 이를 위해 상향링크 채널의 오버헤드가 많이 요구되는 상세한 피드백 정보를 이용하거나 오버헤드는 적지만 불충분한 CQI 정보를 이용하는 방식은 상호 trade-off 관계에 있기 때문에 시스템 처리률을 최적화시키기에 어려움이 있다. 따라서 이 문제를 해결하기 위해, best-M 스케줄링 기법이 제안되었다. best-M 기법에서는 모든 서브채널에 대해서 CQI를 전송하는 대신에 M 서브채널의 CQI 만을 기지국으로 전송함으로써 상향링크 오버헤드를 줄일 수 있게 된다. 본 논문에서는 시스템의 처리량을 더 향상시키기 위해서, 능동적 사용자들의 수를 기반으로 M을 적응적으로 계산하는 적응적 best-M 피드백 스케줄링 방식을 제안하였다. 컴퓨터 시뮬레이션을 통한 제안 방식의 성능 분석 결과로부터 제안된 기법은 상향링크 오버헤드를 현저히 줄이면서 향상된 하향링크 처리률을 제공할 수 있음을 확인하였으며, 특히 best M 방식과 비교할 경우 동일 시스템에서 더 많은 동시 사용자를 지원할 수 있음을 확인하였다. 또한, 본 연구에서는 총 피드백 오버헤드 제한 조건에 따른 시스템 최적 처리률을 얻기 위한 중요 동작 포인트를 얻을 수 있었다.
