We investigate the impact of marital status on the levels of satisfaction of online shoppers in the beauty and cosmetics industry in Vietnam. We find a significant difference in satisfaction between married and divorced/separated online shoppers. More specifically, the latter reveals higher level of satisfaction than the former. Extended analyses further show that this finding is only observed for female online shoppers whilst it is insignificant for their male counterparts. Moreover, we find significant differences in determinants of customer satisfaction between three different groups of online shoppers: single, married, and divorced/separated. While married individuals' satisfaction is affected by all factors (Online shopping experience; Seller Services; External Incentives; Security/Privacy), that of their divorced/separated peers are influenced by only seller services and external incentives. Also, single participants are satisfied with their online shopping driven by their online shopping experience and external incentives. Our findings contribute to the stream of customer satisfaction literature, and to the studies in beauty and cosmetics sector as well as online shopping trends in Vietnam. They contain implications for existing online businesses and new or potential market entrants as to which customer demographic factors have significant influences in terms of customer psychology, behaviour and their satisfaction.

Entrepreneurs with behavioral finance biases are more likely to make irrational or financially detrimental decisions. Understanding financial behavior biases can assist in making sound financial decisions. Behavioral finance is a new topic that can assist researchers in better understanding investor behavior and preferences while purchasing and selling stocks. Using measures such as independent t-tests and average Likert five-point scale scores, this study seeks to determine how entrepreneurs make investment decisions and whether gender makes a difference. The study is empirical, and data from 1000 entrepreneurs were collected through convenience sampling. The study's main findings show that there are numerous factors to consider while investing in stocks, including family planning, children's education, investment security, and recurring income. Both men and women attempt to invest in many asset classes, but certain investments are extremely risky, while others are low risk. As a result, investors should assess risk based on their age and experience rather than their gender; this indicates that an investment in venture capital has nothing to do with gender but everything to do with the investor's age.

Purpose: The goal of this study is to examine what makes young people more likely to use digital banking. This is because digital banking services and their distribution channels are technologically advanced, which can be a double-edged sword between ease of use and resistance to technology. Research design, data and methodology: This study included 320 participants from generation Z in Jakarta who use digital bank and used a quantitative method with PLS-SEM. Results: This study explains how, in addition to usefulness, costs, and self-efficacy, resistance to technology has a direct effect on usage attitudes. Meanwhile, if the attitude of use is preceded by aspects of usefulness, self-efficacy, and awareness, resistance to technology will be felt indirectly. Conclusions: This demonstrated that most discussed factors, such as Ease-of-Use and security of use, are important for Generation Z users but no longer a major consideration in accepting digital banking. Aside from being more open to the use of technology in digital banks, Generation Z also desires a balance of technology services and benefits. The limitations of this study are that it excludes social variables, uses certain generations, and limits the research area to one large city, which can be expanded in future studies.

Development of information and communication technology is changing commerce environment and consumer purchasing behavior has also been changed. Globalization is becoming increasingly prevalent in the world today and many factors such as culture, politics, and economics may influence the applicability of management theories. Concurrently, corporate managers are faced with the challenge of offering usable and useful applications to the local users. Besides, many scholars strongly support that the criteria for M-Commerce adoption in developing countries are different from that of developed countries, due to cultural, security, social, political, economic, and technological aspects. This research tried to investigate the differences on the adoption of mobile commerce between developed and developing countries. In this study, the motivation for studying advanced mobile phone services adoption in the South Korea and Viet Nam is presented. Second, M-Commerce adoption model is introduced as a starting point for the research model. We then integrate price, personal innovativeness, quality dimension and perceived of playfulness into our model. Next, we describe our method and report the results of our analysis. The paper concludes with a discussion of the results from both the South Korea and Viet Nam with implications.

본 논문에서는 국내 가상이동망 사업자(MVNO : Mobile Virtual Network Operator) 제도 도입에 대한 논의를 위해 MVNO의 개념, 국내외 사업자 현황, 규제 동향 및 제도 도입의 효과를 분석한다. 아울러 AHP(Analytical Hierarchy Process, 계층적 분석) 기법을 이용하여 정부의 정책개입에 따른 MVNO 사업자의 효율적인 비즈니스 모델을 도출한다. 이를 위하여 사업자의 주요평가기준으로 경쟁활성화, 투자요인증대 및 경제성을 선정하였으며 자율협상, 부분규제 및 전면 규제의 세 가지 대안을 상정하고 각각의 평가기준별 점수를 비교, 분석한다.

휴대용멀티미디어플레이어(이하 PMP)는 2004년 국내에 등장하여 음악과 더불어 영화 및 동영상을 볼 수 있도록 해주고 있는 인기 있는 개인용 전자기기이다. 그러나 수요가 둔화되고, 업체들의 경쟁이 치열해지면서 새로운 기능, 새로운 서비스에 대한 개발이 대두되고 있다. 최근에는 네비게이션 서비스, 학습서비스가 시행되면서 다시 수요가 살아나는 추세이다. 이에 따라 현재 존속하는 서비스에 대한 평가 및 새로운 서비스에 대한 검증이 요망되고 있다. 본 연구에서는 소비자 니즈 조사를 분석함으로써 현재 이용되고 있는 서비스들의 상황을 분석하고, 신규 서비스에 대한 수요 가치를 분석하였다. 분석 대상이 된 기존 상용 서비스는 게임, DMB, 영화, 음악, 네비게이션, 전자사전, 전자책, 이러닝, 만화, 무선인터넷였고, 신규 서비스는 u-Commerce, u-Health, u-Security, u-Public였다. 본 연구결과 PMP 응용 수요선호도 순위는 영화, TV, 음악 순이었으며, 신규서비스 u-Commerce, u-Health, u-Security, u-Public 옵션들에 대한 구매의향 평균가는 68,102원으로 나타났다.

This work examines whether IT managers adopt of real options such as defer, expand, contract, and abandon in order to cope with ERP risks, which include technological risk, relationship risk with SW vendors, economic risk, and security risk. We collect data of logistics firms in Seoul and its suburbs in 2018 to empirically validate the effect of risks upon the adoption of real options. The results suggest that IT managers adopt all 4 options when facing economic risk and adopt contract and abandon options only when facing security risk. Additionally, we find that IT managers prefers expand option and avoid abandon option when they think ERP compatibility is high.

A fast image encryption system based on substitution and diffusion was proposed, which includes one covering process, one substitution process and two diffusion processes. At first, Chen's chaotic system together with an external 256-bit long secret key was used to generate the key streams for image encryption, in which the initial values of Chen's chaotic system were regarded as the public key. Then the plain image was masked by the covering process. After that the resulting image was substituted with the disturbed S-Box of AES. Finally, the substituted image was diffused twice with the add-modulo operations as the core to obtain the cipher image. Simulation analysis and comparison results with AES and some existing image cryptosystems show that the proposed image cryptosystem possesses the merits of fast encryption/decryption speed, good statistical characteristics, strong sensitivity and etc., and can be used as a candidate system of network security communication.

We question whether Korean IT managers consider real options to reduce risks of cloud service implementation. This work investigates the impact of technology risk, relationship risk, economy risk, security risk upon the intention of IT managers to utilize abandon & expansion options. We also analyze moderation effect of centralization level of decision making between these risks and the utilization of real options. Using the survey questionnaire, we empirically find that technology risk, relationship risk and security risk have significant effect upon abandon option and technology risk, relationship risk, and economy upon expansion option. We also find the evidence that centralization level moderates some risks and the direction of moderation effect is to offset the effect of risks on intention to utilize real options.
