The paper aims to explore the factors affecting potential users of international bank cards in Vietnam. With milestones treaties being signed CPTPP and EVFTA, Vietnam is now exposing itself to the international open environment. Bank card market is at the core of this wind of change, and that is the reason for us to research the intention to use international bank cards. Given that the decision to choose international bank cards could either be the switch from domestic cards or adopting a brand new card, we develop some specific constructs to reflect that consideration, specifically PE and PD, asides from traditional constructs used in TPB and TAM frameworks. The analysis work is conducted using PLS-SEM approach. Our findings reveals that most of our proposed hypotheses are supported, in which SN plays the most important direct role to INT, while total effect of PU on INT is similar to that of SN. The newly introduced PD negatively and significantly impacts INT, and PE also has a positive impact on INT. The findings suggest that overall, it is important for bank card issuers to have a balance approach to the market, with focus on increasing usefulness and reducing potential disadvantages of international bank cards.

본 연구는 새로운 국제 전자결제수단으로 개발된 무역카드(TadeCard)에 대한 검토와 활용 가능성에 관하여 검토한 것이다. 무역카드는 세계무역센터협회가 인터넷을 통하여 국제무역대금을 결제할 수 있는 전자결제시스템으로 개발되었다. 무역카드시스템은 제시되는 전자문서의 일치성 점검 및 국제무역거래의 모든 이행과정을 온라인(on-line) 상에서 전자적으로 이행되는 것을 특징으로 하고 있으며 부대비용 등 경제성 측면에서 여타 결제수단보다 우월한 결제시스템이라고 하고 있다. 그러나 가상공간을 통한 전자결제시스템은 거래당사자에게 대금지급의 확실성과 거래의 안정성 및 신속성 보장이 전제되어야 한다. 실제로 무역카드시스템은 특정 보증보험회사의 보증에 기반을 두고 있어 국제 기업간 거액거래상의 신용취급의 한계점과 금융네트워크 등에서의 취약점을 가지고 있다. 따라서 무역카드가 국제전자결제시스템으로 정착되기 위해서는 정보보안 등 기술적인 안정성이 검증되고 결제상의 신뢰성 보장을 위하여 상업은행들의 참여가 확대되어야 한다. 또한 인터넷상에서 결제가 이루어지기 위해서는 담보권과 유통성이 보장되는 볼레로전자선화 증권 등의 활용과 기존의 모든 종이문서에 의한 결제서류도 전자문서로 대체되어야 한다.

This study is focused on evaluating the computer-integrated just-in-time (CI-JIT) production system of a semi-conductor manufacturing firm in Korea. Approaching the mid-1980s, the emphasis was on low price, low-cost operations, and quality, especially in USA. American companies have shifted output to low-wage countries like the Philippines, Korea, Japan, Malaysia and allied countries that can make quality products at low prices. Korea and other Asian countries forego short-term profits to gain a solid foothold in a product market, recognizing that larger market share leads to lower cost and higher profit in the long run. They bring manufacturers and suppliers together to improve material management and operation management, using project teams that investigate topics, such as Just-In-Time(JIT)manufacturing, among others. The "Kanban" word means "card" in Japanese, and is used to indicate the desired final delivery schedule. The operation for a particular item produced is scheduled for a specific time. The same process is extended to the external suppliers. More recently, the cards are gradually being replaced by electronic procedures that follow the same concept. Its capacity must be capable of handling the various transactions required by the JIT coverage as well as some allowances for expanded applications.

In 1536, two Piedmontese merchants set up workshops in Lyons, and Henri IV encourged further development later in the 16th century. The development of Lyons as a centre of the silk weaving industry was helped by the perfection of drawloom weaving technique there in 1605 by Claude Dangon. In the 17th century, the French silk industry could finally compete with the dominance of the Italian silk trade. The French silk industry was promoted in the mid-17th century under Louis XIV's minister Colbert. In 1667, he published an ordinance creating La Grande Fabrique, a corporation for craftsmen within the silk industry, and Lyons became the undisputed French silk capital. Under Louis X IV, France was becoming the dominant force in Europe in matters of fashion and style. The major innovation of weaving was the Jacquard head attachment, which provided a mechanical means of raising warp threads by a series of punched cards. The are nouveau style did not have much impact on French silk design at the end of the century. Silk manufacturers began to collaborate with haute-couture designers such as the House of Worth. This collaboration with the burgeoning Paris haute-couture industry continued into the 20th century and safeguarded the future production of silk textiles in France.

This research proposes a model of SERVQUAL scale calibration and uses the SERVPERF model to study the relationship between quality of ATM service and customer satisfaction. The research uses the combination of qualitative and quantitative methodology with the Cronbach's alpha reliability analysis, Exploratory Factor Analysis (EFA) method; Confirmation Factor Analysis (CFA) and Structural Equation Modeling (SEM) through SPSS and AMOS 20.0 data analysis software. The survey was conducted with 800 questionnaires with the convenient sampling method. The number of remaining sample for analysis was 779 responses of individual customers using ATM card services of Bank for Foreign Trade of Vietnam (Vietcombank) Vinh Long. The results show that the satisfaction of customers using ATM cards of Vietcombank Vinh Long is influenced by 4 factors with the order of importance as follows: (1) Price; (2) Network; (3) Reliability; (4) Empathy. Thereby, the author suggests some managerial implications to Vietcombank Vinh Long management to enhance the ATM service quality, then improve customer satisfaction. This research still has some limitations: (1) The study does not investigate other influencing factors, (2) The convenient sampling method has not been generalized well, (3) The research is only conducted for Vietcombank.

Recently Yoon et al. proposed the remote user authentication scheme using smart cards. But their scheme has not satisfied security requirements which should be considered in the user authentication scheme using the password based smart card. In this paper, we prove that Yoon et al.'s scheme is vulnerable to a password guessing attack in case that the attacker steals the user's smart card and extracts the information from the smart card. Accordingly, this paper proposes the improved user authentication scheme based on the hash functin and random nonce that can withstand various possible attacks including a password guessing attack. The result of comparative analysis demonstrates that the proposed scheme is more secure and efficient than Yoon et al.'s scheme, with a trivial trade-off to require just a few more exclusive-OR operations.

To investigate the optimum x-ray tube design for the dental radiology, factors affecting x-ray beam characteristics such as tungsten target thickness and anode angle were evaluated. Another goal of the study was to addresses the anode heel effect and off-axis spectra for different target angles. MCNPX has been utilized to simulate the diagnostic x-ray tube with the aim of predicting optimum target angle and angular distribution of x-ray intensity around the x-ray target. For simulation of x-ray spectra, MCNPX was run in photon and electron using default values for PHYS:P and PHYS:E cards to enable full electron and photon transport. The x-ray tube consists of an evacuated 1 mm alumina envelope containing a tungsten anode embedded in a copper part. The envelope is encased in lead shield with an opening window. MCNPX simulations were run for x-ray tube potentials of 70 kV. A monoenergetic electron source at the distance of 2 cm from the anode surface was considered. The electron beam diameter was 0.3 mm striking on the focal spot. In this work, the optimum thickness of tungsten target was $3{\mu}m$ for the 70 kV electron potential. To determine the angle with the highest photon intensity per initial electron striking on the target, the x-ray intensity per initial electron was calculated for different tungsten target angles. The optimum anode angle based only on x-ray beam flatness was 35 degree. It should be mentioned that there is a considerable trade-off between anode angle which determines the focal spot size and geometric penumbra. The optimized thickness of a target material was calculated to maximize the x-ray intensity produced from a tungsten target materials for a 70 keV electron energy. Our results also showed that the anode angle has an influencing effect on heel effect and beam intensity across the beam.
