Interoperability has been deemphasized from the hospital information system in general, because it is operated independently of other hospital information systems. This study proposes a future-oriented hospital information system through the design and actualization of the HL7 clinical document architecture. A clinical document is generated using the hospital information system by analysis and designing the clinical document architecture, after we defined the item regulations and the templates for the release form and radiation interpretation form. The schema is analyzed based on the HL7 reference information model, and HL7 interface engine ver.2.4 was used as the transmission protocol. This study has the following significance. First, an expansion and redefining process conducted, founded on the HL7 clinical document architecture and reference information model, to apply international standards to Korean contexts. Second, we propose a next-generation web based hospital information system that is based on the clinical document architecture. In conclusion, the study of the clinical document architecture will include an electronic health record (EHR) and a clinical data repository (CDR), and also make possible medical information-sharing among various healthcare institutions.

This study was conducted to identify the utilization of public health centers, as well as the individual characteristics and regional characteristics that affect their utilization based on data from the 2016 Community Health Survey, National Statistical Portal, and National Institute of Environmental Research. Independent samples t-tests, variance analysis, and multiple logistic regression analysis were used for analysis. Hierarchical multiple regression was used to analyze individual and regional characteristics. The results of hierarchical multiple regressions revealed that aged regions, women, older age individuals, respondents with lower education level and income level, walking practitioners, nutrition label readers, individuals experiencing depression, those who have received health checkups, those who are not covered by essential care, those who have spouses, and basic livelihood beneficiaries have increased use of public health centers. However, the use of public health centers decreased in stressors, and regions in which the population per 1,000, number of health care workers, health and welfare budget, fiscal independence, and unemployment rate were above the national average. As above, the central government and local governments need to analyze not only individual characteristics such as health behavior and psychological factors, but also regional characteristics, when establishing local health care policy.

DXA is the most commonly used BMD examination equipment with the best performance on reflecting the biological alteration with tiny change of bone density. In spite of the importance of the quality control to maintain the accuracy and precision of the examination, considerable number of hospitals are not conducting QC due to the difficulty and high cost of the phantom product. This study develops the cross revision phantom with 3D printer and the change of the degree of infilling filaments which can be readily secured, and provides the usefulness assessment of the developed phantom by comparing with existing products. The Hounsfield Units of ABS, TPU, PLA, 30% Cu-PLA, and 30% Al-PLA are assessed. The Hounsfield Units result at infilling rate 100% was $-149.74{\pm}2.36$, $-55.62{\pm}7.14$, $-7.68{\pm}3.82$, $87.53{\pm}1.07$, and $1795.20{\pm}16.15$. The L1, L2, L3 BMD of 3D printing phantom with linear regression model were $0.620{\pm}0.010g/cm^2$, $1.092{\pm}0.025g/cm^2$, $1.554{\pm}0.026g/cm^2$ which are statistically relevant to the existing phantom products. This result provides the base line data for various medical phantom produce and capability of proper quality control of DXA equipment.

The purpose of this study was to examine job stress, job satisfaction, and turnover intention of the nurses who work at the comprehensive nursing service units in two academic medical institutions that provide healthcare service at the tertiary care level in Korea. A descriptive study was conducted with the nurses by using self-reported questionnaires. We used descriptive statistics to summarize the data and Mann-Whitney U test for group comparison. The mean scores of job stress, job satisfaction, and turnover intention were $89.17{\pm}12.56$, $107.25{\pm}6.85$, $37.19{\pm}4.86$, respectively. Nurses with religion showed more job stress than those without. Nurses with their age below 30 years old had significantly less job satisfaction than those older than 30 years old. Monthly income was significantly associated with turnover intention in our data. The top three sub-category of the job stress were conflict with physicians, patients and their caregivers, and conflicts with others; and those of the job satisfaction were pay and promotion and task requirement. Job stress, job satisfaction, and turnover intention were significantly correlated. In order to reduce turnover intention of nursing professionals in the comprehensive nursing service, job stress related to issues on relationships with patients, their family, health care providers need to be taken into consideration. Policy and administrative support are needed to improve their work environment.

This article explores some of the ethical issues associated with the fourth industrial revolution and suggests new directions for bioethics education in Korean universities. Some countries have recently developed guidelines and regulations based on the legal and ethical considerations of the benefits and social risks of new technologies associated with the fourth industrial revolution. Foreign universities have also created courses (both classroom and online) that deal with these issues and help to ensure that these new technologies are developed in an ethically appropriate fashion. In South Korea too there have been attempts to enhance bioethics education to meet the changing demands of society. However, bioethics education in Korea remains focused on traditional bioethical topics and largely neglects the ethical issues related to emerging technologies. Furthermore, Korean universities offer no online courses in bioethics and the classroom courses that do exist are generally treated as electives. In order to improve bioethics education in Korean universities, we suggest that (a) new course should be developed for interprofessional education; (b) courses in bioethics should be treated as required subjects gradually; (c) online courses should be prepared, and (d) universities should continually revise course contents in response to the development of new technologies.

Renewable energy (RE) is essential to comprise sustainable societies, especially, in rural villages of developing countries. Furthermore, application of off-grid RE systems to health care can improve the quality of life. In this research, a RE-based vaccination supply management system was constructed to enlarge the cold-chain in developing countries for the safe storage and delivery of vaccines. The system was comprised of the construction of RE plants and development of vaccine carriers. RE plants were constructed and connected to health posts in local villages. The cooling mechanism of vaccine carriers was improved and monitoring devices were installed. The effect of the system on vaccine cold-chain was evaluated from the field test and topographical analysis in the southern village of Nepal. RE plants were normally operated for the vaccine refrigerator in the health post. The modified vaccine carriers had a longer operation time and better temperature control via monitoring and RE-based recharging functionality. The topographical analysis estimated that the system can cover larger region. The system prototype showed great potential regarding the possibility of a sustainable and enlarged cold-chain. Thus, RE-based vaccine supply management is expected to facilitate vaccine availability while minimizing waste in the supply chain.

Objectives : When a patient who attempts suicide visits the emergency room, it is important that the departments of emergency medicine, internal medicine, and psychiatry communicate with each other and prioritize treatment. This study was conducted to verify the effectiveness of the multidisciplinary emergency consultation system (ECS) for drug intoxicated patients. Methods : We retrospectively analyzed the data from medical records prior to the ECS, from July 2017 to May 2018, and after the ECS, from July 2018 to May 2019, to verify the effectiveness of the system. Results : After the ECS, admission to open wards was significantly higher than to the intensive care units (χ²=8.567, p=0.014). In addition, the proportion of consultations to the department of psychiatry among patients admitted to other departments tended to increase (χ²=4.202, p=0.053), and the time required for consultation response decreased (Z=-2.031, p=0.042). As a result of the consultation, the proportion of the patients who had been transferred to the department of psychiatry was increased (χ²=4.692, p=0.043), and the time spent to transfer tended to decrease (Z=-1.941, p=0.052). Conclusions : After implementing the ECS for drug intoxicated patients, unnecessary intensive care unit admissions, consultation response time, and the time spent to transfer were reduced, and the rate of consultation referrals and transfer rates increased. This means that the multidisciplinary consultation system rapidly provided essential medical services to patients at lower medical costs.

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.
