  • This study aims at classifying and analyzing the business models of reverse overseas direct purchasing through online shopping-malls. After analyzing the current status of the reverse overseas direct purchasing online markets, this study identifies relevant critical business factors and synthesizes prior studies to construct and analyse the business models. This study proposes that the business models can be classified into five types according to the operation modes and three types according to the delivery methods. So theoretically 15 business models can be identified. For each business model this study analyzes the characteristics and the pros & cons. It also suggests deployment strategies for companies by considering cost reduction, brand establishment, customer management, customer aquisition, and easiness from the business perspective. From the customers perspective, cost reduction, reliability, royalty, ease to purchase, and accessibility can be considered according to the types of operation mode. The main contribution of this study is to provide the basic classifications and structures of reverse overseas direct purchasing business models systematically. As the result, our study evaluates the business models that which one is better than others in a situation in terms of company and customer. Lastly, we talk about limits and future prospects of the study.

  • This paper provides an integrated view on human and system interaction in advanced and automated systems, which adopting computerized multi-functional artifacts and complicated organizations, such as nuclear power plants, chemical plants, steel and semi-conduct manufacturing system. As current systems have advanced with various automated equipments but human operators from various organizations are involved in the systems, system safety still remains uncertain. Especially, a human operator plays an important role at the time of critical conditions that can lead to catastrophic accidents. The knowledge on human error helps a risk manager as well as a designer to create and control a more credible system. Several human error theories were reviewed and adopted for forming the integrated perspective: gulf of execution and evaluation; risk homeostasis; the ironies of automation; trust in automation; design affordance; distributed cognition; situation awareness; and plan delegation theory. The integrated perspective embraces human error theories within three levels of human-system interactions such as affordance level, psychological logic level and trust level. This paper argued that risk management process should dealt with human errors by providing (1) reasoning improvement; (2) support to situation awareness of operators; and (3) continuous monitoring on harmonization of human system interaction. This approach may help people to understand risk of human-system interaction failure characteristics and their countermeasures.

  • The coronavirus disease 2019 (COVID-19) pandemic made it necessary for medical schools to restructure their curriculum by switching from face-to-face instruction to various forms of flexible learning. Flexible learning is a student-centered approach to learning that has received interest in many educational sectors. It is a critical strategy for expanding access to higher education during the pandemic. As flexible learning includes online, blended, hybrid, and hyflex learning options, learners have the opportunity to select an instruction modality based on their needs and interests. The shift to flexible learning in medical education took place rapidly in response to the COVID-19 pandemic, and learners, instructors, and schools were not prepared for this instructional change. Through the lens of the technology acceptance model, human agency, and a social constructivist perspective, I examine students, instructors, and educational institutions' roles in successfully navigating the digital transformation era. The pandemic has also accelerated the use of advanced information and communication technologies, such as artificial intelligence and virtual reality, in learning. Through a review of the literature, this paper aimed to reflect on current flexible learning practices from the instructional design and educational technology perspective and explore emerging technologies that may be implemented in future medical education.

  • To make a critical revision on the inherited social problems throughout the time in Mexico, not always turns out to be easy task, especially when the subject is lent to approach it from diverse perspective, one of them, the educative one. To analyze the low quality of the educative supply is complex subject. One of the maximum profits of institutional revolutionary Mexico was the creation of the Public Education Ministry in 1921. In the post-revolutionary and modern period, the seventies were characterized to be applied to the growth the infrastructure and the fortification of the educative system following the policy of "modernization and development". From the eighties, to lift the quality of the education was considered like one of the specific rules in the strategy of the call "educative revolution". In the nineties, through political programs and agreements, structural changes within the educative system were carried out with the intention to lift the quality of the services. In synthesis, the perspective in the educative policy of Mexico during the last thirty years of century xx, or post-revolutionary period, can be understood, from at least five specific conditions: educative profits in cover, modifications in the educational programs and contents, profits in the political agreements between the agents who take part within the educative system, changes and modifications to the laws applicable to the education, and; the search of the fairness through the compensatory programs. This paper tries to give answer to questions such as: The educative system reflects the ideals of the revolution? The present educative system is the product of a truncated revolution or the fruit of an untimely democracy?

  • In this essay, we problematize the problematics of the KMIS SOLOMO research agenda. We propose that the SOLOMO agenda is a conditioned product of the various assumptions, biases, premises, and presuppositions that the field of IS collectively succumbs to and shares, and thus needs to be problematized to arrive at a new set of research questions for the field. The problematization begins with the ontology that underlies the agenda. We argue that the agenda is largely drawn from a dichotomic, deep ontology of Human vs. Technology. While such ontology is neither right nor wrong in its own right, we suggest it is what underlies and influences the field's whole mode of inquiry including its research agenda. We propose an alternative ontology, the Actor-Network Theory (ANT), which as a flat ontology provides a radically different set of research questions for the field. Next we take issue with the teleology of the SOLOMO agenda, and suggest that the telos of the agenda, and of the field of IS and the whole of Management discipline together, are anchored upon the capitalist episteme so that it creates a significant hole in its teleological scape. While not in any sense calling for an ideological demagogue, we propose that the field of IS should open itself to an alternative teleology including a leftist perspective. We draw upon the Critical Management Studies (CMS) to explore how further problematization can be made on the SOLOMO agenda, generating questions about its performativity, denaturalization, and reflexivity. As a result of the discussions, a list of new problematized research questions for the SOLOMO agenda is generated. In the end we state the motivation of the essay and call for a critical refurbishing of the field of IS.

  • 본 연구에서는 비판적 인종 이론의 관점에서 학교 수학 교육에서 인종 문제를 다룬 연구들을 분석하였다. 본 연구는 두 부분으로 구성 된다. 첫 번째 부분에서는 국내외 문헌 연구를 바탕으로 사회 정의를 위한 수학의 의미와 이를 주제로 한 연구들의 동향을 분석한다. 이를 통해 사회 정의를 위한 수학 교육의 의의와 방향을 도출한다. 두 번째 부분에서는 비판적 인종 이론을 토대로 사회 정의를 위한 국내 수학 관련 연구를 검토한다. 본 연구에서는 비판적 인종 이론의 기본 원리인 인종적 영속성 또는 인종 사실주의, 자유주의 비판, 교차성의 관점에서 기존 연구들을 검토하였다. 분석 결과 현재 인종 문제와 관련한 사회 정의를 위한 수학 교육에서는 학생들 스스로 문제를 찾고 이를 수학 수업에서 논의하는 과정에 대한 연구가 부족하며, 수학 교실 안에서 학생 스스로 차별의 요소를 자각하고 이를 해결하는 접근법에 대한 고민이 필요하다는 점을 발견할 수 있었다. 또한 그동안 수학 교육 연구에서 인종 문제가 다른 차별 요소와 필연적으로 연결되어있다는 관점은 충분히 다루어지지 않은 부분으로 후속 연구의 필요성을 확인할 수 있었다. 이러한 시사점은 향후 인종 문제와 관련한 사회 정의를 위한 수학 교육 연구 방향을 설정하는데 근거 자료로 활용될 수 있다.

  • This review aimed to evaluate the quality of case reports where acupotomy was performed according to the CAse REport (CARE) guidelines and the Joanna Briggs Institute (JBI) critical appraisal checklist. Case reports on acupotomy published in Korea from 2013 to October 2020 were included in this review. A total of 28 acupotomy related case reports were selected, and a quality evaluation was verified using the CARE guidelines and JBI critical appraisal checklist. Among the case reports, spinal conditions/diseases were most commonly reported. The overall complete reporting rate for each study was relatively high (median of 63.4% according to the CARE guidelines and 73.4% according to JBI critical appraisal checklist for case reports and 62% for case series). However, low reporting rates were determined in several subcategories namely, "Intervention adherence and tolerability," "Timeline," "Diagnostic challenges," "Patient perspective," and "Adverse or unanticipated events" for case reports, and "Reporting of the presenting site/clinic," "Demographic information," "Statistical analysis," and "Clear criteria for inclusion" for case series. When reporting cases where acupotomy was performed, it is recommended that the CARE guidelines are followed to improve the quality of research. In addition, new guidelines and tools for the clinical situation of Korean medicine should be developed.

  • Risks and uncertainty are unavoidable problems in management of projects. Therefore, project managers should not only prevent risks, but also have to respond and manage them. Risk management has become a critical interest subject in the construction industry for both practitioners and researchers. This paper presents critical risk factors of office building projects in the construction phase in Ho Chi Minh City, Vietnam. Data was collected through a questionnaire survey based on the likelihood and consequence level of risk factors. These factors fell into five groups: (i) financial risk factors; (ii) management risk factors; (iii) schedule risk factors; (iv) construction risk factors; and (v) environment risk factors. The research results showed that critical factors affecting office building projects are natural (i.e., prolonged rain, storms, climate effects) and human-made issues (i.e., soil instability, safety behaviors, owner's design change) and the schedule-related risk factors contributed to the most significant risks for office buildings projects in the construction phase in Ho Chi Minh City. They give construction management and project management practitioners a new perspective on risks and risk management of office buildings projects in Ho Chi Minh City and are proactive in the awareness, response, and management of risk factors comprehensively.

  • 본 연구는 사용자 중심 디자인 과정을 디자인 픽션 방법에 적용하여 사용자 친화적인 디자인픽션 방법론을 제안한 연구이다. 디자인 픽션은 미래에 대한 비평적 담론 위에 구상한 예측 시나리오를 디자인의 관점에서 물리적으로 구현하는 방법이다. 이러한 디자인 픽션은 HCI와 인터랙션 디자인 분야에서 미학적 혹은 실험적 접근으로써 많은 관심을 받고 있는 방법이지만 아직 학계에서 완전히 정립되지 않은 생소한 디자인 방법론이다. 특히, 사용자와의 접점을 모색하며 당면 문제를 해결하는 사용자 중심의 관점에서는 다루어지지 않고 있다. 현재의 문제를 기반으로 미래를 예측하며 디자인 관점에서 시나리오를 정립하는 선행디자인이 날로 중요해짐에 따라 본 연구는 그러한 선행디자인을 실험적으로 제시하는 디자인 픽션 방법이 사용자 중심의 관점에서 다루어지는 것이 필요하다고 보았다. 이에 따라, 본 연구에서는 사용자 중심 디자인 프로세스 중 사용자의 행동이나 인지에 직관적이고 직접적인 영향을 주고자 고안된 어포던스 개념을 기존 디자인 픽션의 과정에 접목하였다. 주제와 어포던스 개념을 구체적으로 디자인에 응용하고자 고안된 Design with Intent Toolkit을 시각디자인 전공 3학년 학생들에게 활용하였고, 이를 디자인 픽션의 과정으로 발전시켜 다양한 시각적 결과물을 완성하였다. 이러한 과정을 통해 본 연구는 기존의 비평적, 실험적 영역으로 국한되었던 디자인픽션 방법론외 대안으로 사용자 친화적인 디자인 픽션 방법론을 새롭게 제안하고자 한다.
