The study explores the evolving landscape of overseas expansion strategies by Korean corporations, focusing on recent geopolitical tensions, the COVID-19 pandemic, and disruptions in global supply chains. It emphasizes the challenges faced by industries producing high-value products and delves into the concept of "Friend-Shoring" policies in the United States, leading major Korean companies to invest in local semiconductor, battery, and automotive factories. Recognizing the potential fragmentation of Korea's manufacturing sector, the paper introduces the "Mother Factory" strategy as a policy initiative, inspired by Japan's model, to establish core production facilities domestically. The discussion unfolds by examining the cases of major companies in Japan and the United States, highlighting the need for Korea to adopt a mother factory strategy to mitigate risks associated with friend-shoring policies. Inspired by Intel's "Copy Exactly" approach, the paper proposes a Korean mother factory model integrating smart factory technology and digital twin systems. This strategic shift aims to enhance responsiveness to geopolitical challenges and fortify the competitiveness of Korean high-tech industries. Finally, the paper proposes a Korean Mother Factory based on smart factory concepts. The suggested model integrates smart factory technology and digital twin frameworks to enhance responsiveness and fortify competitiveness. In conclusion, the paper advocates for the adoption of a comprehensive Korean Mother Factory model to address contemporary challenges, foster advanced manufacturing, and ensure the sustainability and competitiveness of Korean high-tech industries in the global landscape. The proposed strategy aligns with the evolving dynamics of the manufacturing sector and emphasizes technological advancements, collaboration, and strategic realignment.

본 연구는 2005년과 2007년에 시행한 중소기업기술통계조사에 모두 응한 중소기업 중 전자부품, 영상, 음향, 통신 장비 업체(KSIC 32) 142개사를 대상으로 외부 자원 활용과 흡수능력이 2년 후 경영성과와 혁신성과에 어떠한 영향을 미치는지, 또한 흡수능력이 이들 관계를 어떻게 조절하는지를 실증 분석하였다. 분석 결과, 공동기술개발 여부와 정부지원액으로 측정한 외부 자원 활용은 성과에 유의미한 영향을 미치지 않았고, 매출액에 대해서만 R&D투자비는 정(+)의, R&D인력비는 부(-)의 영향을 끼쳤다. 그리고 흡수능력의 조절효과는 측정방식과 독립변수에 따라 다르게 나타났다. 즉, 공동기술개발을 수행할 때의 성과는 R&D투자비가 증가할수록 향상했지만, R&D인력비는 반대로 작용했다. 그리고 정부의 자금지원이 늘어날수록 성과가 향상하는 기업은 R&D투자비가 낮거나 R&D인력비가 높은 기업이었다. 이러한 연구 결과는 중소기업의 외부 자원 활용이 내부 역량을 대체하지 못하며 오히려 흡수능력을 축적하여 외부 자원 활용의 효과를 극대화 할 필요가 있음을 보여준다. 또한, 공동기술개발을 수행할 때에는 중소기업의 적극적인 R&D투자가 필요하며 정부의 자금지원은 R&D인력을 보유하고 있으나 자금을 확보하지 못해 독자적인 기술개발이 어려운 기업에 더욱 효과적이다. 본 연구는 제한된 산업과 표본에서 이루어진 한계가 있지만, 종단적 자료를 통해 인과관계를 규명함으로써 기존 연구들의 한계를 극복하였다.

최근의 연구는 개방형 혁신이 전략적 측면에서 혁신에 어떠한 영향을 미치는지에 중점을 두고 있어 개방성의 형태와 관련된 연구는 부족하다. 또한, 개방형 혁신을 위해 개방을 해야 하지만 혁신을 보호해야 하기도 한다는 모순이 존재한다. 최근 이와 관련하여 혁신 보호 연구의 필요성이 확대되고 있다. 따라서 본 연구는 개방성의 형태가 제품혁신에 미치는 영향을 살펴보고, 개방성의 형태와 제품혁신의 관계는 전유성 메커니즘에 따라 어떻게 달라지는지 탐구하였다. 본 연구는 OECD에서 개발하고 배포하는 CIS(Community Innovation Survey)를 기반으로 국내 실정에 맞게 작성된 KIS(Korean Innovation Survey) 자료를 사용하였다. 연구의 주요 연구결과를 요약하면 다음과 같다. 첫째, 개방성의 형태는 제품혁신에 정(+)의 영향을 미친다. 구체적으로 외부 탐색은 활용적 혁신에 정(+)의 영향을 미쳤으며, 협업은 탐험적 혁신에 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 전유성 메커니즘은 개방성의 형태와 제품혁신의 관계에 정(+)의 조절효과를 가진다. 구체적으로 공식적 전유성 메커니즘은 외부 탐색과 활용적 혁신의 관계에 정(+)의 조절효과를 보였으며, 비공식적 전유성 메커니즘은 협업과 탐험적 혁신의 관계에 정(+)의 조절효과를 가지는 것으로 나타났다. 본 연구는 다음과 같은 기여를 할 것으로 기대된다. 첫째, 개방성의 형태를 기존의 방식과는 다르게 외부 탐색과 협업으로 구분하였으며 이에 따라 제품혁신에 미치는 영향을 파악하여 제품혁신의 유형과 적합한 개방성의 형태를 파악하였다. 둘째, 전유성 메커니즘의 특성에 따라 개방성의 형태와 제품혁신의 관계에 정(+)의 조절효과를 미치는 것을 파악하여 개방성의 형태와 제품혁신의 유형에 따라 더 적합한 전유성 메커니즘 유형을 파악하였다.

Background: Organized cervical screening has decreased the incidence of cervical cancer. However, screening strategies vary in different countries. Objectives: We performed a systematic review to evaluate the economic aspects of different screening methods. Materials and Methods: We searched databases and then data were abstracted from each study. We evaluated articles based on different types of screening tests as well as screening age and intervals, and using incremental cost effectiveness ratio via calculating quality adjusted life years (QALY), or life years gained (LYG) per cost. We compared the incremental cost-effectiveness ratio (ICER) of each study using GDP per capita. Furthermore, we compared national guidelines with recommendations of cost-effectiveness studies in different countries. Results: A total of 21 articles met our criteria, of which 19 studies showed that HPV DNA testing, 13 suggested an age of 30 years or more, and 10 papers concluded that at least a 5-year or longer interval were the most cost-effective strategies. In some countries, the national guidelines did not match the recommendations of the cost-effectiveness studies. Conclusions: HPV testing, starting at age 30 years or older and repeated at 5-year or longer intervals, is the most cost-effective strategy in any setting. Closer collaboration with health economists is required during guideline development.

In mobile ad-hoc networks (MANETs), nodes are mobile in nature. Collaboration between mobile nodes is more significant in MANETs, which have as their greatest challenges vulnerabilities to various security attacks and an inability to operate securely while preserving its resources and performing secure routing among nodes. Therefore, it is essential to develop an effective secure routing protocol to protect the nodes from anonymous behaviors. Currently, game theory is a tool that analyzes, formulates and solves selfishness issues. It is seldom applied to detect malicious behavior in networks. It deals, instead, with the strategic and rational behavior of each node. In our study,we used the dynamic Bayesian signaling game to analyze the strategy profile for regular and malicious nodes. This game also revealed the best actions of individual strategies for each node. Perfect Bayesian equilibrium (PBE) provides a prominent solution for signaling games to solve incomplete information by combining strategies and payoff of players that constitute equilibrium. Using PBE strategies of nodes are private information of regular and malicious nodes. Regular nodes should be cooperative during routing and update their payoff, while malicious nodes take sophisticated risks by evaluating their risk of being identified to decide when to decline. This approach minimizes the utility of malicious nodes and it motivates better cooperation between nodes by using the reputation system. Regular nodes monitor continuously to evaluate their neighbors using belief updating systems of the Bayes rule.

Background: The burden due to cancers is an emerging public health concern especially in resource-limited countries like Nigeria. The WHO estimates that cancer kills more people than tuberculosis, HIV/AIDS and malaria combined. As people in Nigeria and other developing countries are beginning to survive infectious diseases, there is an observed epidemiologic transition to chronic diseases, such as cancers. In 2008, 75 out of 1,000 Nigerians died of cancer. Despite the rising incidence and public health importance, Nigeria lacks an organized and comprehensive strategy to deal with cancers. Materials and Methods: This article reviewed 30 peer-reviewed manuscripts on cancer care in four countries. It highlights the limitations to cancer care in Nigeria; due to lack of awareness, low health literacy, absence of organized screening programs, inadequate manpower (in terms of quality and quantity) as well as limited treatment options. Results: This review led to the formulation of a proposal for Nigerian National Cancer Policy, mainly drawn from effective strategies used in Canada, Brazil and Kenya. This is a vertical cancer program that is patient-centered with an emphasis on tobacco control and cancer disease screening (similar to Canada and Brazil). Additionally, it emphasizes primary cancer prevention (similar to Kenya). Its horizontal integration with other disease programs like HIV/AIDS will improve affordability in a poor resourced country like Nigeria. Capacity building for health professionals, hub-and-spoke implementation of screening services, as well as investment in effective treatment options and increased research in cancer care are essential. International 'twinning collaborations' between institutions in richer countries and Nigeria will enhance effective knowledge translation and improve the quality of patient care. Conclusions: A national cancer policy must be developed and implemented in Nigeria in order to overcome the present limitations which help contribute to the observed increases in cancer morbidity and mortality rates. Cancer control is feasible in Nigeria if the nation was to consider and employ some of the cost-effective strategies proposed here.

PURPOSE. This study aimed to investigate whether the accuracy of intraoral scanners is influenced by different scanning strategies in an in vitro setting, through a systematic review and meta-analysis. MATERIALS AND METHODS. This review was conducted in accordance with the PRISMA 2020 standard. The following PICOS approach was used: population, tooth impressions; intervention, the use of intraoral scanners with scanning strategies different from the manufacturer's instructions; control, the use of intraoral scanners following the manufacturers' requirements; outcome, accuracy of intraoral scanners; type of studies, in vitro. A comprehensive literature search was conducted across various databases including Embase, SciELO, PubMed, Scopus, and Web of Science. The inclusion criteria were based on in vitro studies that reported the accuracy of digital impressions using intraoral scanners. Analysis was performed using Review Manager software (version 5.3.5; Cochrane Collaboration, Copenhagen, Denmark). Global comparisons were made using a standardized mean difference based on random-effect models, with a significance level of α = 0.05. RESULTS. The meta-analysis included 15 articles. Digital impression accuracy significantly improved under dry conditions (P < 0.001). Moreover, trueness and precision were enhanced when artificial landmarks were used (P ≤ 0.02) and when an S-shaped pattern was followed (P ≤ 0.01). However, the type of light used did not have a significant impact on the accuracy of the digital intraoral scanners (P ≥ 0.16). CONCLUSION. The accuracy of digital intraoral scanners can be enhanced by employing scanning processes using artificial landmarks and digital impressions under dry conditions.
