Credit capital from customers' savings deposit (CSD) of banks has an important meaning in the business activities of the banking industry. There are many factors that influence the CSD satisfaction with banks. Certain changes have been made when there are fluctuations due to COVID-19. The article is based on an analysis assessing the factors that influence the CSD satisfaction of Vietnamese commercial banks in the context of COVID-19. The authors use a sample of 1,639 CSD. The results show that there are three variables that positively affect CSD satisfaction, including legal provisions of the Central bank (Legal), policies and mechanisms of commercial banks (Policy), and products of commercial banks (Product). Accordingly, in order to contribute to strengthening this capital mobilization of savings deposit, the Central bank of Vietnam needs to play a pivotal role in the regulations of the banking system to ensure its stability; control well monetary policy, interest rates, and inflation to keep a stable position in the economy; and provide timely financial support packages to enhance the confidence of CSD. Moreover, Vietnamese commercial banks need flexible policies and mechanisms to stimulate CSD; strengthen support on deposit rates for CSD; and diversify products to easily adapt to each CSD's situation.

The point of Bush administraion’s foreign policy is to support the promotion and stability of Democracy in Iraq and counter terrorism and spread of WMD with his strong propulsive force caused by his reelection. In such an environment, there are his leadership, his team, himself, Kim Jung Il, and a new understanding of North Korea after September 11 as the effective factors of Bush administration’s policy toward Pyongyang. Bush administration’s foreign policy of North Korea also shows the process of North Korea’s nuclear weapon program and the future scenario of the Korean Peninsula with "the persistence of solving North Korea’s nuclear weapon program such as the method having done in Lybia", "the holding unconditional talks with Pyongyang, and "the continual concerns with human rights in North Korea." The purpose of Bush administration’s foreign policy of North Korea is to make North Korea do not support terrorism rather than remove the nuclear weapon in North Korea. The process of outlining South Korea’s policy toward North Korea must be considered for "national interest" with reasonable analyses not just hopes For this, South Korea must access systematically human rights of North Korea, prepare projects for a daring approach on North Korea, and strengthen South Korea’s defense ability toward North Korea with deep alliance with U.S and systematize the mutual understanding channel between U.S and South Korea. In conclusion, South Korea must try to get specific methods and practices about Bush administration’s foreign policy of North Korea with national wisdom

대형 시스템에 있어서 안정도는 매우 중요하며 특히 분산 제어로 안정 가능한 시스템에 관한 연구는 점차 중요성을 더해 가고 있다. 본 논문은 몇 개의 국부 시스템으로 구성된 대형 시스템에서 각 국부 시스템의 제어기가 자기 자신의 입력만을 제어하고 또한 자기 자신의 출력만을 관측하는 경우에 대형 시스템이 안정하기 위한 충분 조건을 제시하였다. 이 충분 조건은 Sezer와 Huseyin이 제시한 조건을 확상시킨 것이며 상호 연관된 시스템을 표현하는 시스템 모델은 가장 일반적이다. 특수한 경우로써 각 부 시스템이 단일 입력이고 가제어 companion형으로 주어졌을 때 본 논문에서 사용한 증명 방법카 유사하게 Ikeda와 Siljak이 제시한 충분 조건을 증명하였다.

A polymer electrolyte membrane (PEM) fuel cell has been getting large interest as a typical issue in useful applications. The PEMFC is composed of a membrane, catalyst and the bipolar plate. SnOx:F films on SUS316 stainless steel were prepared as a function of substrate with using electron cyclotron resonance-metal organic chemical vapor deposition (ECR-MOCVD) in order to achieve the corrosion-resistant and low contact resistance bipolar plates for PEM fuel cells. The SnOx:F films coated on SUS316 substrate at surface plasma treatment for excellent stability, before/after heat treatment for good crystalline structure and microwave power for were characterized by X-ray diffraction (XRD), auger electron microscopy (AES) and field emission-scanning electron microscopy (FE-SEM). The SnOx:F film coated on SUS316 substrate with various process parameters were able to observe optimum interfacial contact resistance (ICR) and corrosion resistance. It can be concluded that fluorine-doping content plays an important function in electrical property and characteristic of corrosion-protective film.

In this paper, the biometric data is transmitted in real time from the IoT environment is runoff, forgery, alteration, prevention of the factors that can be generated from a denial-of-service in advance, and the security strategy for the biometric data to protect the biometric data secure from security threats offer. The convenience of living in our surroundings to life with the development of ubiquitous computing and smart devices are available in real-time. And is also increasing interest in the IOT. IOT environment is giving the convenience of life. However, security threats to privacy also are exposed for 24 hours. This paper examines the security threats to biological data to be transmitted in real time from IOT environment. The technology for such security requirements and security technology according to the analysis of the threat. And with respect to the biometric data transmitted in real time on the IoT environment proposes a security strategy to ensure the stability against security threats and described with respect to its efficiency.

The copolymerization of HEMA with different hydrophilic and hydrophobic co-monomers allows for the manipulation of their intrinsic properties. 2-Hydroxyethylmethacrylate (HEMA)-based hydrogels thus are of great interest due to their outstanding physico-mechanical properties and chemical stability. The idea to use HEMA in order to create thermo-sensitive polymers was based on our assumption that thermal-sensitivity comes from a suitable hydrophilic-hydrophobic balance of macromolecules. In this work we have chosen N-vinyl pyrrolidone as a hydrophilic co-monomer with the relatively hydrophobic HEMA due to its good polymerizing properties as well as its non-toxicity in a polymer state and deserved recognition as a biocompatible material. As a result, copolymerization of NVP and HEMA was successful in obtaining new types of thermo-sensitive polymers composed of hydrophilic and hydrophobic monomers.

일본 후쿠시마 원전 사고로 해양에 많은 방사능이 누출되면서 해양 방사선 탐지에 대한 많은 관심이 고조되었다. 본 논문에서는 해양에서 방사선 탐지를 위한 MCNP 시뮬레이션을 하였다. 공기중과 달리 해양환경은 수심, 온도, 압력, 염분 등으로부터 센서의 안정성을 확보해야한다. 또한, 해양환경에서는 방사선이 많이 차폐된다. 따라서 방사선 차폐율이 낮은 하우징을 선택하는 것이 목적이다.

The composites such as Sn-CNTs, $SnSb_{0.5}$-CNTs and $CoSb_3$-CNTs have attracted much attention in the past years owing to their good overall properties. In these samples, intermetallic compounds show high specific capacities. Recently, interest in metal oxides such as $Al_{2}O_{3}$, MgO and $TiO_2$ has been largely stimulated by the realization that they can improve the cycling stability of the Li-ion battery electrodes. The reversible capacity of the $TiO_2$/CNTs composite reaches 168 mAh $g^{-1}$ at the first cycle and remains almost constant during long-term cycling. In this study, a nanocomposite of $TiO_2$/CNTs was prepared by sol-gel method and its electrochemical properties as anode materials for Li-ion batteries were studied by galvanostatic cycling, cyclic voltammograms (CV) and electrochemical impedance spectroscopy (EIS).
