나트륨(소금)의 경우 식품에 관능적 특성 부여 및 가공과정에 필수적인 물질이나 과다 섭취의 경우 고혈압 등 심혈관계 질환을 발생을 증가시키는 등 사회적인 문제가 되고 있다. 특히 한국인의 경우 장류, 젓갈 및 김치 등의 식품문화가 발달되어 WHO의 권장섭취량의 2배 이상 섭취하고 있는 실정이다. 나트륨 저감화의 경우 국민복지 향상, 의료비용 절감 및 사회적 편익비용 발생 등의 이유로 국가적 차원에서 나트륨 절감이 시급한 상황이다. 현재 식품의약품안전처 및 보건복지부 등에서 나트륨 저감화를 위한 다양한 정책 등을 추진하고 있다. 또한 세계적으로 무기염류 대체소금, 염미증진제 및 향미개선제 등의 개발 노력이 활발히 이루어지고 있는 상황이다. 그러나 낮은 관능적 특성 및 무기염류의 과량 사용에 관한 부작용 등으로 인하여 급증하는 소금대체 및 보완제 시장수요에 미치지 못하는 실정이다. 따라서 저염화 및 관능적으로 우수한 소금 대체소재 및 염미 증강물질 개발이 요구된다. 염미 및 지미상승 식물성 발효 조성물(SAP)의 경우 분리대두단백 등의 식물성 원료와 전통 장류의 제조원리를 응용한 염미증진제 또는 향미개선제이다. 관능적 특성을 조사한 결과 기존 사용되는 저염 소재에 비하여 염미 등의 관능적 특성이 우수하여 염미 및 관능적 특성 증진 소재로 활용 가능성이 높았으며 무기염류의 단점인 낮은 관능적 특성 및 무기염류에 의한 부작용 등의 우려가 없는 소재이다. 향후 염미 및 지미 상승 식물성 발효 조성물(SAP) 등의 활용방안 개발 및 적용분야 확대 등으로 국내 저염 식품 산업의 전반적 발전에 도움이 될 것으로 생각된다.

This study analyzed for the radioactive shielding wall, which shields the medical linear accelerator. This allows to evaluate the level of waste with respect to the shield wall, which accounts for more than half of the cost of dismantling later linac facility. In addition, by analyzing the waste processing method according we discuss the way to obtain the benefits in terms of dismantling cost. Results of the simulate, the amount sufficient to screen the amount of neutron radiation occurring in the shielding wall linac was measured. And neutron activation analysis results were analyzed nuclides more than about 20. This analysis was in excess of that, $^{24}Na$, $^{45}Ca$, $^{59}Fe$ nucleus paper deregulation concentration. The value is reduced is greater the deeper the depth of the shielding wall concentration. Based on this, three specific areas (E, F, G) was estimated to be impossible to landfill or recycling. The rest area was estimated to be buried or recycled if possible more than a predetermined depth.

Recently, it has become possible to collect, store, process, and analyze data generated in various fields by the development of the technology related to the big data. These big data technologies are used for clinical results analysis and the optimization of clinical trial design will reduce the costs associated with health care. Therefore, in this paper, we are going to analyze clinical results and present guidelines that can reduce the period and cost of clinical trials. First, we use Sqoop to collect clinical results data from relational databases and store in HDFS, and use Hive, a processing tool based on Hadoop, to process data. Finally we use R, a big data analysis tool that is widely used in various fields such as public sector or business, to analyze associations.

The Healthcare supply chain management has recently attracted attention as a critical tool to improve service quality and reduce healthcare operational cost. Improving large hospital supply chain performance has become increasingly important as healthcare organizations strive to improve the service quality, while reducing the ever-increasing healthcare cost. This paper explores the strategic areas where the traditional supply chain management may enhance the overall performance of the large hospitals. Based on the literature review and relevant case analysis, this paper argues that the visibility, information sharing and standardization are the critical factors for deploying the supply chain principles, and also proposes the supply chain framework for efficient planning and execution, the use of RFID-enabled system for the end-to-end traceability of medical products, and cross-docking system for minimizing the inventory level in the hospital supply chain. Implications of the study findings are discussed.

Recently, the field of telemedicine is growing rapidly due to the COVID-19 pandemic. However, the cost of telemedicine services is relatively high, since cloud computing, video conferencing, and cyber security should be considered. Therefore, in this paper, we design and implement a cost-effective P2P-based telemedicine system. It is implemented using the widely used the open source computing platform, Raspberry Pi, and P2P network that frees users from security problems such as the privacy leakage by the central server and DDoS attacks resulting from the server/client architecture and enables trustworthy identifying connection system using SSL protocol. Also it enables users to check the other party's status including body temperature in real time by installing a thermal imaging camera using Raspberry Pi. This allows several medical diagnoses that requires visual aids. The proposed telemedicine system will popularize telemedicine service and meet the ever-increasing demand for telemedicine.

Purpose: Little is known regarding the extent to which dying patients with chronic obstructive pulmonary disease (COPD) receive life-sustaining procedures and palliative care in U.S. hospitals. We examine hospital cost trends and the impact of palliative care utilization on the use of life-sustaining procedures in this population. Methods: Retrospective nationwide cohort analysis was performed using National Inpatient Sample (NIS) data from 2005 and 2014. We examined the receipt of both palliative care and intensive medical procedures, defined as systemic procedures, pulmonary procedures, or surgeries using the International Classification of Diseases, 9th revision (ICD-9-CM). Results: We used compound annual growth rates (CAGR) to determine temporal trends and multilevel multivariate regressions to identify factors associated with hospital cost. Among 77,394,755 hospitalizations, 79,314 patients were examined. The CAGR of hospital cost was 5.83% (P<0.001). The CAGRs of systemic procedures and palliative care were 5.98% and 19.89% respectively (each P<0.001). Systemic procedures, pulmonary procedures, and surgeries were associated with increased hospital cost by 59.04%, 72.00%, 55.26%, respectively (each P<0.001). Palliative care was associated with decreased hospital cost by 28.71% (P<0.001). Conclusion: The volume of systemic procedures is the biggest driver of cost increase although there is a cost-saving effect from greater palliative care utilization.

Purposes: Diabetes is a metabolic disorder that requires continuous care in order to prevent complications, as it can impose a critical burden on families and society due to various complications, including terminal renal failure, non-traumatic lower extremity amputation, and adult blindness. The usual sources of care are "specified private clinics, public health centers, or other facilities to visit when ill or when health-related advice is needed". These usual sources of care offer preventative services, have a high overall satisfaction rate in terms of public health care, and decrease the inpatient rates and medical costs of medical aid recipients. This study analyzed the current status of diabetic patients over 20 years of age based on their possession of a usual source of care, and the effects of this possession on the frequency of their medical service usage and its costs. Methodology: Based on data from the 7th Korea Health Panel, a Tobit analysis was used to analyze the different factors that can affect the frequency of medical service usage and its costs for diabetic patients with and without a usual source of care. Findings: The medical costs of diabetic patients with a usual source of care decreased in terms of inpatient, and the outpatient visits and inpatient costs of the group with a usual source of care in the form of a mainly-visiting doctor decreased more than those of the group with a mainly-visiting medical institution only. Practical Implications: Having a usual source of care can increase the treatment continuity, leading to reduced inpatient, and having a mainly-visiting doctor as the usual source of care further increases the treatment continuity. Based on these results, a new policy is needed to increase and strengthen diabetic patients? possession of a usual source of care.

Chronic pain is one of the leading causes of hospital visits. It not only affects the patients themselves but also has a major negative impact on their families and society. In this study, we investigated epidemiology of musculoskeletal disorders induced chronic pain among general population based on Korea National Health and Nutrition Examination Survey database and also analysed how it influenced on the use of medical services. This study was done by using the data of 5th Korea National Health and Nutrition Examination Survey (KNHANES V), taking aged 20 years and over adults as research subjects. The EuroQoL-5 Dimension Index(EQ-5D) was used as a survey instrument. T-test, chi-square test and multivariate logistic regression were used for statistical analysis. Subjects with chronic pain had a higher likelihood than control group to use medical services(odds ratio : 5.858, confidence interval 3.636-9.438). Controlling for existence of chronic pain, more women were likely to use medical services than men(1.156, 0.707-1.889). Age, gender and household income level did not affect the use of medical services. Proper control of chronic pain is very helpful in improving patient's quality of life and it also accounts for a large proportion in suppressing excessive consumption of medical services. Anesthesia and pain medicine specialists have superior knowledge about analgesics and anticonvulsants than other physicians do and also have specialized skills to perform procedures like nerve blocks in treating chronic pain. Therefore Anesthesia and pain medicine specialists need to play a leading role in managing chronic pain.
