Dengue virus transmission is a viral infection disease between humans and Aedes mosquitoes. Dengue is ubiquitous throughout the tropics and subtropical zones, where 1/3 of the global population live. The weather in Korea is also changing to subtropical weather, resulting in increased vulnerable Korean population to dengue virus transmission. It is important to control and prevent the dengue risk with track-recording & monitoring system. It is also required to have the control system to treat and monitor dengue patients with various cases such as regions, ages, genders according to the track-record of the disease. In this paper, we developed a Dengue Control & Prevention System, which can monitor and control dengue outbreaks in real-time with in-vitro diagnostic devices. Dengue Control & Prevention System is composed of in-vitro diagnostic device, which is a fluorescent immunoassay, and real-time monitoring system. In the future, we expect that our Dengue Control & Prevention System can be upgraded to have various disease information from Korea Disease Control and Prevention Agency for government policies and diseases control in Korea.

Calcific tendinitis is characterized by inflammation around calcium hydroxyapatite crystal deposits. Minimally invasive extracorporeal shock wave therapy (ESWT) has been postulated to be an effective treatment option for treating calcific tendinitis. In clinical practice, shock waves usually are aimed at the painful area after palpation and not focused. It has been known that exact fluoroscopic focusing of ESWT at the calcific deposit for treatment of calcifying tendinopathy is highly effective. Ultrasound is a simple, inexpensive and radiation-free diagnostic tool that has been used to demonstrate tendinopathy including calcific tendinitis. However, focusing of shock wave under ultrasound is less well established. We present a patient in whom large calcific tendinitis of gluteus medius was completely resolved by exact focusing of ESWT by ultrasound with literature review.

Korean medical device industry has laid the foundation for full-fledged growth and development with the G7 medical engineering technology development project that started in 1995, and the medical device production in 2020 increased by 8.52 times and the export by 13.94 times, compared to those in 2001. In early years, electronic medical devices such as ultrasound imaging device contributed greatly to Korean medical industry, but top ranks in medical device production and export in Korea has shifted recently to in vitro diagnostic medical devices and dental implants. However, the share of imported medical devices in the Korean medical device market have not changed much; it still ranges in 60 to 70%, as the Korean medical device industry produces and exports mid- to low-priced medical devices, and technology-intensive and capital-intensive high-priced medical devices are mainly imported. In this paper, we compare the leading medical devices produced by major Korean companies and those by global top medical device companies to suggest strategies for the Korean medical device companies to enter the global market.

병원들은 연 평균 3,000개, 중소병원 급은 연 평균 120개가 폐업을 하고 있으며, 병원들의 무한경쟁시대가 시작되면서 병원의 차별화를 위해 서비스 강화가 무엇보다 중요하게 되었다. 또한 2015년 세계 헬스 케어 산업의 전체 시장 규모는 약 15,505억 달러의 매출을 기록할 것으로 전망된다. 특히, 의료 IT와 체외진단의료기기 분야에서 작년 대비 약 7~8% 성장률이 전망되고 있다. 이러한 시장동향에 만춰 시장을 선도적으로 선점할 절대적인 필요가 요구 되고 있다. 이에 병원내 환자 행동 관리 시스템을 개발하여 국민 복지 증진과 더불어 기술적, 사회적, 경제적 효과를 극대화 할 수 있도록 한다.

Background: The coronavirus disease 2019 pandemic has been challenging the healthcare service, i.e., the vitalization of the point of care accompanying self-testing in vitro diagnostic medical devices (IVDs). This study aims to suggest priority criteria to classify self-testing IVDs using the analytic hierarchy process technique. Methods: Two dimensions of the characteristics embedded in the IVDs and the diseases to be diagnosed with self-testing IVDs were parallelly considered and independently investigated. In addition, three expert panels consisting of laboratory medical doctors (n=11), clinicians (n=10), and citizens (n=11) who have an interest in the selection of self-testing IVDs were asked to answer to questionnaires. Priorities were derived and compared among each expert panel. Results: First of all, ease of specimen collection (0.241), urgency of the situation (0.224), and simplicity of device operation (0.214) were found to be the most important criteria in light of the functional characteristics of self-testing IVDs. Medical doctors valued the ease of specimen collection, but the citizen's panel valued self-management of the disease more. Second, considering the characteristics of the diseases, the priority criteria were shown in the order of prevalence of diseases (0.421), fatality of disease (0.378), and disease with stigma (0.201). Third, medical doctors responded that self-testing IVDs were more than twice as suitable for non-communicable diseases as compared to communicable diseases (0.688 vs. 0.312), but the citizen's group responded that self-testing IVDs were slightly more suitable for infectious diseases (0.511 vs. 0.489). Conclusion: Our findings suggested that self-testing IVDs could be primarily classified as the items for diagnosis of non-communicable diseases for the purpose of self-management with easy specimen collection and simple operation of devices, taking into account the urgency of the situation as well as prevalence and fatality of the disease.

Human papillomaviruses (HPVs) are major causes of cervical cancer. Sixteen high risk HPVs, including HPV 16, HPV 18, HPV31, HPV 33, HPV 35, HPV 39, HPV 45, HPV 51, HPV 52, HPV 53, HPV 56, HPV 58, HPV 59, HPV 66, HPV 68, and HPV 69 are found in cervical cancer. HPVs 16 and 18 are mainly presented in 70% of cervical cancer. Therefore, identifying the presence of these high-risk HPVs is crucial. The objective of this study is to establish the HPV ViroCheck for detecting 16 HR-HPVs and genotypes of HPVs 16 and 18, as well as to analyze the analytical performance of HPV ViroCheck. We performed the analytical sensitivity of HPV E6 / E7 genes of 16 high risk HPVs to confirm the limit of detection. Then, a cross reactivity of HPV ViroCheck with microorganisms and viruses related to the cervix were analyzed for analytical specificity. Analytical sensitivity of high risk HPV genotypes ranged from 1 to 100 copies when using cloned DNAs. The limit of detection was 10 cells for both SiHa and HeLa cells. Cervical-related microorganisms and viruses did not show cross-reactivity to HPV DNA. Moreover, the intra- and inter-assay coefficient variations (CVs) were below 5%. In conclusion, HPV Virocheck will be useful for the detection of 16 HR HPVs, as well as HPV 16 and HPV 18 genotypes rapidly.
