As one designs a building, one should have to consider its characters and functions according to its own use. Recently many professional buildings used to be designed by specialized design firms with their own experience and specialty to vitalize the functions of the buildings. Especially the design of the hospital is really needed more concern from the beginning of design ordering because it is pursuing the most specialty in architectural designs and therefore it can not be managed with general architects. The purpose of this study is to present the references for resonable promotions of hospital design in the future with the analysis of the suitability in hospital design ordering and the process after design competition in Korea.

Strengthening of the health system is a safety imperative, especially in a crisis as caused by the ongoing COVID-19 pandemic. While there is a need for enhancing the number and skill sets of the public health professionals, especially the frontline workers, it will be prudent to use the digital health technologies, including artificial intelligence, in enhancing the capacity of the healthcare professional education and delivery. However, it has to be ensured that an ethical and safe approach is adopted to develop and use digital health technology and, ethically appropriate training is imparted, to enhance the capacity of the human resources for health, leading to an overall health system strengthening.

Now a day, Wireless Sensor Networks (WSNs) are being widely used in different areas one of which is healthcare services. A wireless medical sensor network senses patient's vital physiological signs through medical sensor-nodes deployed on patient's body area; and transmits these signals to devices of registered medical professionals. These sensor-nodes have low computational power and limited storage capacity. Moreover, the wireless nature of technology attracts malicious minds. Thus, proper user authentication is a prime concern before granting access to patient's sensitive and private data. Recently, P. Kumar et al. claimed to propose a strong authentication protocol for healthcare using Wireless Medical Sensor Networks (WMSN). However, we find that P. Kumar et al.'s scheme is flawed with a number of security pitfalls. Information stored inside smart card, if extracted, is enough to deceive a valid user. Adversary can not only access patient's physiological data on behalf of a valid user without knowing actual password, can also send fake/irrelevant information about patient by playing role of medical sensor-node. Besides, adversary can guess a user's password and is able to compute the session key shared between user and medical sensor-nodes. Thus, the scheme looses message confidentiality. Additionally, the scheme fails to resist insider attack and lacks user anonymity.

Purpose: The purpose of this study was to examine the relationship between social support (family, healthcare provider, friends/peer), treatment belief, hope, and health status in patients on hemodialysis, and to identify direct and indirect effects of the variables on patients' health status. Methods: The self-regulation model was used to establish a path model. Data were collected from 240 patients. Multidimensional Scale of Perceived Social Support, Revised Illness Perception Questionnaire, Herth Hope Index, and Medical Outcomes Study Short Form-12 were used. Data were analyzed using the SPSS and AMOS programs. Results: The model was supported by fit statistics ($x^2=3.33$, p=.343, GFI .995, RMSEA .021, AGFI .968, NFI .986, CFI .999, TLI .993). Family and friends/peer support showed a significant direct influence on hope, while healthcare provider support directly influenced treatment belief. Social support, treatment belief, and hope directly and indirectly influenced health status, explaining 28.7% of the variance. Conclusion: These results show mechanisms underlying connections between social support and health status by demonstrating impact of social support and showing treatment belief and hope as mediators between social context and outcomes. To promote health of patients on hemodialysis, it is necessary for patient, family, healthcare professional, and friends to collaborate.

Purpose: The purpose of this study was to identify the role of the physical environment in task interruptions in the healthcare settings. Many dangerous events such as airplane crash and medical errors are the result of human errors and, these errors are often the result of interruptions during a critical task of professional workers. In fact, the physical environment that determines accessibility and visibility among people affects interruptions significantly, but architectural studies have given little attention to the management of interruptions. Methods: Therefore, the researcher reviewed research literature in other fields to find out how the physical environment affected interruptions. Many studies were from management, human factors, and health care, but few from architecture. First the author examined the impact of interruptions, second described the social context of interruptions and the role of the physical environment. Results: Findings included that description of the physical environment was not very clear in studies from management and human factors, while little work had been done on interruptions in architecture. The author proposed study design that compensated shortcomings of each field by combining approaches from management, human factors, and architecture. Implications: Unit design strategies such as distributed nurse stations can affect interruptions and layout analysis such as space syntax analysis can evaluate visibility and accessibility of floor plans in the preliminary design phase.

Purpose : The purpose of this study was to understand and describe the experiences of the advanced nurse practitioner (APN) system used by healthcare providers including APNs, doctors who worked with APNs, and APN master's course professors at a graduate school. Methods : Qualitative data were collected via snowball sampling. The participants were nine APNs, six doctors, and three professors. They were divided into three focus groups, each of which consisted of all three types of healthcare providers. Data were collected via interviews with the three focus groups conducted from September to October 2019. All interviews were audiotaped and transcribed verbatim. The transcribed data then underwent qualitative content analysis. Results : Based on the data, we extracted four themes and 14 categories. The themes were "Role and system of APNs started according to healthcare environment changes", "Optimal healthcare provider to ensure quality of care", "Confused role and system of APNs due to incomplete medical law", and "Tasks for the stable operation of the APN system." Conclusion : For quality treatment and safety of patients, a legal basis must be established for the APN system. For its stable operation, social consensus regarding legislation about APNs' scope of practice is required. Finally, a discussion is necessary about the integration of APNs' 13 fields.

인삼은 가공처리방법에 따라 홍삼과 발효홍삼으로 구분된다. 또한, 이들의 가공처리방법에 따라 인삼의 효능을 나타내는 사포닌의 함량이 차이가 있다. 따라서, 본 연구에서 인삼, 홍삼 및 발효홍삼이 대식세포에서 LPS에 의한 염증에 대한 항염효과 및 그 기전을 규명하고자 하였다. 마우스의 대식세포인 RAW264.7 세포에서 LPS에 의해 유도되는 염증관련인자인 NO 및 COX-2의 발현 및 TNF-$\alpha$, INF-$\gamma$ 그리고 NF-${\kappa}B$의 활성을 인삼, 홍삼 그리고 발효홍삼에 의한 항염효과 차이를 비교 하였다. 그 결과, 인삼 및 홍삼 그리고 발효홍삼 모두에서 LPS에 의한 NO의 생성을 억제시키는 것을 확인하였으며, TNF-$\alpha$ 및 INF-$\gamma$의 생성 또한 억제시키는 것을 알 수 있었다. 또한, 인삼 및 홍삼 그리고 발효홍삼 모두 COX-2의 발현 및 LPS에 의한 $I{\kappa}B$의 인산화를 억제시킴으로써 NF-${\kappa}B$의 활성을 억제시키는 것임을 알 수 있었다. 홍삼이 인삼과 발효홍삼에 비하여 NO의 생성을 더 효과적으로 억제시키는 것은 각각의 제조과정에서 나타나는 인삼사포닌의 조성의 차이에 따른 것으로 추정된다. 본 연구는 단순한 동물세포 수준에서의 비교 차이이며 좀 더 정확한 기전의 규명을 위해서는 향후 동물실험을 통한 비교 실험이 수행되어야 할 것이다.
