Caregivers have been exposed to tremendous stress in their daily work. Similar with that of the patients, the staffs also are treated as individuals who need appropriate respite environment and psychological support to mitigate work stress. Therefore, by overviewing the caregiver safety environment, as a method for the study, theories and design concepts are reviewed with noticeable design cases that reflect the theories as a supportive environment design strategy; social support, self-control, and positive distraction. Moreover, the types of design strategies are summarized for their application and whom the result expected regarding wellbeing of staff. Consequently, the design strategies are shown two noticeable groups. The design concept and goal on to support the staffs’ safe environment used to focus on stress reduction by access to nature and create readily accessible respite space for meditation. The staffs can use these spaces to meditate, collect their thoughts, and recharge before returning to the stressful patient care area. Another type of the design concept is to create a concrete stress prevention environment by proving the work efficiency design and work safety zone from an accidently occurred violence. However, those two types of design strategies actually reflect mutual influence. To maintain the staff’s wellbeing, it is naturally accepted and shared that the value of supportive environment design is essentially considered as the same as that of an economical or functional hospital product.

새로운 Pseudo-TN IPS 모드 액정 셀에 대한 특성 해석 연구

윤형진,윤석인,윤상호,원태영 대한전자공학회 2004 電子工學會論文誌-SD (Semiconductor and devices) Vol.41 No.8

본 논문에서는 IT(In-plane switching foisted nematic) 모드를 기반으로 광 투과 특성을 개선시킨 Pseudo-TN IPS(Pseudo-Twisted Nematic In-Plane Switching) 모드를 새롭게 제안하고 그 광 투과 특성을 분석하였다. PTN-IPS 모드의 경우 개구율을 향상시켜 투과율 면적을 향상시킴으로써 종래의 IT 모드보다 약 25%정도의 높은 광 투과 특성을 나타내었으며, 전압인가에 따른 광 투과율의 변화가 선형적이므로, 광 투과율 조절을 위한 액정의 제어가 IT 모드에 비해 용이함을 확인하였다. 또한, IT 모드에 비해 수평방향 대비비는 약 8%정도 특성이 열화 되었으나 수직 방향에 있어서는 약 20%이상의 특성개선을 확인 할 수 있었다. 이와 더불어, 기존 IT 모드가 가지고 있는 샐 갭에 대한 특성 및 장점을 가지고 있어, 차세대 액정 셀을 개발하는데 유용하게 사용될 것이라 생각된다. In this paper, we propose Pseudo-TN IPS mde(Pseudo-Twisted Nematic In-Plane Switching mode) based on IT(In-plane switching Twisted nematic) mode that increase contrast ratio from improving optical characteristics and analyze the characteristics of Pseudo-TN IPS uude. Optical transmittance is 25% higher for the PTN-IPS mode than for the IT mode. Because aperture ratio of the PIN-IPS is increased. And the control of Liquid Crystal for adjusting optical transmittance is more easier than IT mode, because optical transmittance variation is linear with applying voltage. Contrast ratio is 8% lower for the PTN-IPS mode than for the IT mode in the horizontal direction. But, Contrast ratio is 20% higher for the PTN-IPS mode than for the IT mode in the vertical direction. It has also cell gap margin and many benefits of IT mode, this may be used very well in the future LC Cell design.

We determined the relationship between the progression of immunoglobulin A nephropathy (IgAN) and the A1818T polymorphism in intron 2 of Angiotensin II type 2 receptor (AT2R) gene, which might play protective roles in the pathogenesis of IgAN. Patients with biopsy-proven IgAN were recruited from the registry of the Progressive REnal disease and Medical Informatics and gEnomics Research (PREMIER) which was sponsored by the Korean Society of Nephrology. A1818T polymorphism of AT2R gene was analyzed with PCR-RFLP method and the association with the progression of IgAN, which was defined as over 50% increase in baseline serum creatinine level, was analyzed with survival analysis. Among the 480 patients followed for more than 10 months, the group without T allele had significantly higher rates of progression of IgAN than the group with T allele (11.4% vs. 3.9%, p=0.024), although there were no significant differences in the baseline variables such as initial serum creatinine level, the degree of proteinuria, and blood pressure. In the Cox’s proportional hazard model, the hazard ratio of disease progression in the patients with T allele was 0.221 (95% confidence interval for Exp(B): 0.052-0.940, p=0.041) compared to that of without T allele. In conclusion, A1818T polymorphism of AT2R gene was associated with the progression of IgAN.

국가지정입원격리병상의 시설별 면적구성에 관한 연구 - 2016년 국가지정입원격리병상 확충사업대상을 중심으로

Purpose: Since the facility guidelines for National Designated Isolation Unit wards(NDIUs) had been edited since 2016, all hospital who want to expand or install NDIU should adapt the new guidelines. Instead of providing area requirement, by the way, only essential or optional facility requirements are suggested except patient bedroom in the guidelines. So, as analyze area and area composition of the NDIUs, it could be expected that this study has a role as an area planing reference for not only NDIU but also another airborne infection isolation room. Methods: For the area analysis, 18 sample hospitals are selected among 2016 year applicants. All rooms in NDIUs are grouped as zones whether those are negative air pressurized or not and programed room or not. At the end, area of the zones are summarized and analysed a relationship between area increase and bed number by both correlation analysis and regression analysis. In addition, department usable and gross area per bed, N/G ratio, G/N ratio, and average area ratio of each zone is calculated. Results: First of all, rooms in none negative air pressurized zone of the NDIUs haven't shown a regular installation so that only those in negative air pressurized zone are targeted for the area analysis. Second of all, patient room unit(0.92) and support area(0.79), by correlation analysis, are correlated with total net area. Patient room unit(0.94) and total net area(0.79) are also shown a correlation with bed number. Department usable area($R^2=0.63$, y=36.278x + 102) and patient room unit area($R^2=0.89$, y= 27.993x - 0.8924) has a relationship with bed number by regression analysis. Average N/G is shown as 0.85 and G/N 1.36. Average area ratio of circulation, doffing area, patient room unit, and support area are 25.4%, 9.1%, 50.9%, and 14.6% in order. Implications: This study is a basic research for exploring the NDIUs guidelines to find resonable evidence to develop it for its practical use. Still, it is possibly expected that the guideline is to be developed by post occupancy evaluation in the area of where minimum requirement or facility grade needs to be defined, and by further studies with various perspectives.
