본 논문에서는 인터넷 쇼핑몰에서 신용카드 전자결제에 대해 다루고자 한다. 전자결제는 전자상거래 분야에서 매우 흥미 있는 주제 중에 하나이다. 전자결제 방식 중 신용카드 결제는 현재 인터넷 쇼핑몰 전자 결제의 대부분을 차지하고 있다. 최근 중국의 인터넷 쇼핑몰은 매우 빠른 속도로 성장하고 있으며, 동시에 전자결제에 대한 관심도 많이 높아지고 있다. 아직은 다른 나라와는 달리 중국에서 신용카드 결제가 활성화되지 못하였지만, 향후 신용카드의 사용은 매우 빠르게 증가할 것으로 기대되고 있다. 본 논문에서는 중국의 인터넷 쇼핑몰에서 신용카드 결제에 영향을 미치는 요인들에 대해 조사하고, 이 요인들과 신용카드 사용의도와의 관계를 분석하기 위한 모형을 제시한다. 그리고 제시한 모형을 검증하기 위해 중국의 인터넷 쇼핑몰 사용자를 대상으로 설문조사를 수행하고 구조방정식모형으로 분석한다.

이 연구는 Y대 도서관의 전자저널 컨소시엄 중 Academic Press의 2000년분 IDEAL 이용통계를 대상으로 인쇄본 병행구독 전자저널과 단독구독 전자저널의 전문 내려받기 수를 기준으로 그 이용현황을 평가하였으며, 평가결과를 대상으로 비용편익 및 효과를 분석해 보았다. 그 결과 Y대 도서관에서는 전자 저널로만 구독하는 것보다 인쇄본과 전자저널을 동시에 구독하는 병행구독 전자저널의 전문을 더 많이 이용한 것으로 나타났다. 또한 IDEAL의 비용편익을 분석한 결과, 편익은 거의 없는 것으로 나타난 반면에 비용효과는 매우 높은 것으로 분석되었다. 이 연구결과에 따라 전자저널을 구독해서 이용을 활성화할 수 있는 방법으로서 대학도서관들이 전자저널 구독대행사에 임시사용권을 요청하고, 전자저널에 대한 이용자교육, 다양한 이용통계의 분석, 이용자 만족도 조사를 실시할 것을 제언하였다.

Small firms are considered as the last mile in electronic networks of business enterprises. Since small firms lack in their resources and capabilities for IT deployment, it seems a challenging project to make them electronically linked to their trading partners. This study aims to investigate the factors that influence the intent of small firms to adopt electronic linkage to their trading partners. This study considers the context where small firms already have transaction relationships with partner firms and where their adoption of electronic linkage may influence the nature and performance of the transactional relationships. This study considers the expected value of electronic linkage and the joint actions of the trading firms as the major factors. Its research model also includes traditional factors such as influences from the industry and the trading partner, the support of CEO, and the readiness of the trading partner. Based on the survey data from more than 1000 small firms, the present study performs regression analysis and finds that all but one factor are significant in explaining the variations in the adoption intention of small firms. The exception is the joint action, which is shown to decrease the intention. Based on the results, this study offers business and policy implications that would be useful to business managers and policy makers.

In Vietnam, tax compliance has become an important goal in the tax reform strategy. In the context of technology 4.0, the application of the electronic tax system is of great significance to small- and medium-sized enterprises (SMEs). The paper explores factors influencing electronic tax compliance of SMEs in Vietnam. Data from 402 SMEs, who are business taxpayers, was selected through a researcher-designed questionnaire survey method. The results indicate that four groups of factors have significant effects on electronic tax compliance among Vietnamese SMEs. These groups include Taxpayer Awareness (TA), Perceived Ease of use (PTE), Vietnamese tax administration (VTA,) and Efficiency of Vietnamese tax policy (VTP). The factor analysis was adopted; Cronbach's alpha coefficients were calculated, exploratory factor analysis (EFA) was used. The findings found that among these four groups, the most influencing factor is taxpayer awareness. It is suggested that the Vietnamese government should pay attention to promote and support SMEs to raise full awareness of tax obligations. This could be done through various methods such as conducting workshops for updating tax policies and short courses to business taxpayers of electronic tax compliance. The study is expected to provide some important implications for policy-makers and practitioners in tax policy reform in Vietnam.

직업교육 훈련의 효율과 참여도를 극대화할 수 있는 방안을 모색하기 위한 신뢰성 높은 수요조사 방법을 찾고자 하는 것을 목적으로 하였다. 정확한 수요조사는 훈련의 질을 높일 수 있는 가장 중요한 요소라 할 수 있다. 뿐만 아니라 부정확한 수요조사에 의한 훈련은 낮은 참여도로 인해 비효율적인 훈련성과를 나타낼 수 밖에 없다. 수요조사는 크게 우편, 전화, 대면, 전자 수요조사 4가지 방법이 사용되고 있다. 본 논문에서는 목포대학교 국가인적자원개발 컨소시엄 사업, 지역 산업 맞춤형 인력양성 사업의 훈련을 위해 실시하였던 수요조사를 설명하였고 그 중 효과적인 수요조사 방법을 제안하였다.

For about the past decade and a half research efforts into cognitive radio networks (CRNs) have increased dramatically. This is because CRN is recognized as a technology that has the potential to squeeze the most out of the existing spectrum and hence virtually increase the effective capacity of a wireless communication system. The resulting increased capacity is still a limited resource and its optimal allocation is a critical requirement in order to realize its full benefits. Allocating these additional resources to the secondary users (SUs) in a CRN is an extremely challenging task and integer programming based optimization tools have to be employed to achieve the goals which include, among several aspects, increasing SUs throughput without interfering with the activities of primary users. The theory of the optimization tools that can be used for resource allocations (RA) in CRN have been well established in the literature; convex programming is one of them, in fact the major one. However when it comes to application and implementation, it is noticed that the practical problems do not fit exactly into the format of well established tools and researchers have to apply approximations of different forms to assist in the process. In this survey paper, the optimization tools that have been applied to RA in CRNs are reviewed. In some instances the limitations of techniques used are pointed out and creative tools developed by researchers to solve the problems are identified. Some ideas of tools to be considered by researchers are suggested, and direction for future research in this area in order to improve on the existing tools are presented.

Objectives: The objective of this study was to investigate the relationship between the level of Electronic Medical Record (EMR) system adoption and healthcare information technology (IT) infrastructure. Methods: Both survey and various healthcare administrative datasets in Korea were used. The survey was conducted during the period from June 13 to September 25, 2017. The chief information officers of hospitals were respondents. Among them, 257 general hospitals and 273 small hospitals were analyzed. A logistic regression analysis was conducted using the SAS program. Results: The odds of having full EMR systems in general hospitals statistically significantly increased as the number of IT department staff members increased (odds ratio [OR] = 1.058, confidence interval [CI], 1.003-1.115; p = 0.038). The odds of having full EMR systems was significantly higher for small hospitals that had an IT department than those of small hospitals with no IT department (OR = 1.325; CI, 1.150-1.525; p < 0.001). Full EMR system adoption had a positive relationship with IT infrastructure in both general hospitals and small hospitals, which was statistically significant in small hospitals. The odds of having full EMR systems for small hospitals increased as IT infrastructure increased after controlling the covariates (OR = 1.527; CI, 1.317-4.135; p = 0.004). Conclusions: This study verified that full EMR adoption was closely associated with IT infrastructure, such as organizational structure, human resources, and various IT subsystems. This finding suggests that political support related to these areas is indeed necessary for the fast dispersion of EMR systems into the healthcare industry.

본 연구는 노인들의 직업 활동과 삶의 질과의 관련성을 규명하여 노인일자리 프로그램에 기초자료를 제공하고자 국민건강영양조사 자료를 사용하여 수행하였다. 조사대상은 65세 이상 인구 1,472명을 대상으로 하였다. 조사방법은 t-test, ANOVA 그리고 다단계회귀분석을 사용하였다. 연구결과 직업을 가진 노인들의 삶의 질이 직업이 없는 노인들에 비해 삶의 질이 높게 나타났다(${\beta}=0.041$, p=0.000). 특히, 근로형태에서는 상용직이 평균0.93점(p=0.005), 근로시간은 전일제가 평균 0.91점(p=0.079), 직업분류에서는 전문직이 평균0.96(p=0.044)점으로 삶의 질이 높았다. 노인일자리 사업에서 연구결과를 고려하여 일자리사업을 수행하여 노인들의 삶의 질을 높일 필요가 있다고 생각한다.
