Purpose: The purpose of this study is to analyze the deployment characteristics of korean and foreign mobile hospitals and to draw out the advantages and disadvantages based on the movement of patients. Methods: The arrangement and user movement lines of foreign mobile hospitals which were actually utilized, and the arrangements and user movement lines of korean mobile hospitals are compared and analyzed. Based on the results of the comparative analysis, we suggest the optimal placement of mobile hospital in Korea. Results: The recently developed Korean mobile hospitals have made many improvements. However, there is no practical use case for the mobile hospital in Korea, so it is necessary to establish the basis for the mobile hospital development site and the site access considerations. In addition, there is no detailed analysis of the movement of the administrators other than the medical staff, and it is considered that research on safe waste disposal is further needed. Implications: It is highly likely to be used as a basic data to find out the combination method of mobile hospitals that can efficiently deal with disasters through the arrangement and movement analysis of mobile hospitals in Korea and abroad.

The study tries to find out basic elements that make a public-open-space(POS) of building in proper use as intended in building code. Several previous studies haves mentioned POS's physical elements but were not enough to encourage the use of them; but imposed impractical regulations for the building axle. We made a field survey on POS in 13 buildings and found that the building itself acts an important role to encourage the use of POS. We classified the case study buildings into centripetal building and centrifugal building according to the use, spatial organization, and location of building in urban setting. With the cross combination of these two factors, ie., with centripetal building or centrifugal building, and with the level of abundance of POS's physical elements, we propose 4 types of POS.

Purpose: To assess long-term clinical outcomes and factors influencing refractive change after implantation of hydrophilic (Akreos AO) and hydrophobic (Acrysof IQ) acrylic intraocular lens. Methods: After phacoemulsification, intraocular lens was inserted in the bag (Akreos AO for 84 eyes and Acrysof IQ for 19 eyes). Uncorrected visual acuities (UCVA), refraction in both spherical equivalent (SE) and astigmatism were compared longitudinally in more than 2 years follow-up. Factors associated with SE change ≥0.5 diopter (D) after Akreos AO implantation were analyzed with logistic regression. Results: Although Akreos AO showed hyperopic change mainly within 6 months, UCVA and astigmatism change were not statistically significant during follow up (+0.15 ± 0.43 D, p = 0.027). UCVA, SE, astigmatism were not changed after Acrysof IQ implantation and not significantly different between two groups during follow up. Preoperative anterior chamber depth was a sole factor associated with SE change ≥0.5 D after Akreos AO implantation (p = 0.006).Conclusions: Possible hyperopic shift after Akreos AO implantation should be considered in setting target diopter, especially in eye with shallow anterior chamber.

실리콘 기판위에서의 Cr-Doped SrZrO₃ 박막의 저항변화 특성

양민규,고태국,박재완,이전국,Yang, Min-Kyu,Ko, Tae-Kuk,Park, Jae-Wan,Lee, Jeon-Kook 한국재료학회 2010 한국재료학회지 Vol.20 No.5

One of the weak points of the Cr-doped SZO is that until now, it has only been fabricated on perovskite substrates, whereas NiO-ReRAM devices have already been deposited on Si substrates. The fabrication of RAM devices on Si substrates is important for commercialization because conventional electronics are based mainly on silicon materials. Cr-doped ReRAM will find a wide range of applications in embedded systems or conventional memory device manufacturing processes if it can be fabricated on Si substrates. For application of the commercial memory device, Cr-doped $SrZrO_3$ perovskite thin films were deposited on a $SrRuO_3$ bottom electrode/Si(100)substrate using pulsed laser deposition. XRD peaks corresponding to the (112), (004) and (132) planes of both the SZO and SRO were observed with the highest intensity along the (112) direction. The positions of the SZO grains matched those of the SRO grains. A well-controlled interface between the $SrZrO_3$:Cr perovskite and the $SrRuO_3$ bottom electrode were fabricated, so that good resistive switching behavior was observed with an on/off ratio higher than $10^2$. A pulse test showed the switching behavior of the Pt/$SrZrO_3:Cr/SrRuO^3$ device under a pulse of 10 kHz for $10^4$ cycles. The resistive switching memory devices made of the Cr-doped $SrZrO_3$ thin films deposited on Si substrates are expected to be more compatible with conventional Si-based electronics.

CNT/AgNW Multilayer Electrodes on Flexible Organic Solar Cells

양민규,Jeon‑Kook Lee 대한금속·재료학회 2020 ELECTRONIC MATERIALS LETTERS Vol.16 No.6

In this study, the fabrication of transparent CNT/AgNW multilayer electrodes on PET substrates using a spray coating processis investigated. A CNT/AgNW multilayer electrode exhibited a Rshof 50 Ω/square with a transparency of 94% at 500 ~550nm wavelength without substrate. We examined the effects of the sheet resistance and transparency of CNT/AgNWmultilayer electrodes based on the performance of the OSC cells. The use of sprayed CNT/AgNW multilayer electrodes will advance the mass production of inexpensive and highly efficient flexible polymer organic solar-cell based films using a roll-to-roll based process.

Recently, the disaster situation has been diversified and compounded worldwide as well as in Korea. And the damage scale of each disasters have increased, and following economic loss is also increasing immensely. In Korea, especially the out break frequency of large-scale disasters has increased. Disasters caused by earthquakes are also very likely to occur. When a major accident such as Mauna resort collapse accident, Ferry sewol sinking accident occurred, systematic emergency medical care at the site at the time of disaster occurred in order to operate an emergency medical facility corresponding to the site, which is not systematic. The need for this service is urgent. If highly reliable emergency medical system function at appropriate times in the disaster site, secondary damage can be reduced and the whole situation would be back to normal shortly. Therefore, it is necessary to provide an emergency medical system capable of quickly and safely responding to disaster sites in relation to various damage scale. For the purpose, thorough analysis on mobile medical units of inside and outside the country was accomplished. As a result, Mobile Medical Unit of outside the country are trailer type, tent type, container type etc. At home, these types have been studied and will be proposed early next year as a temporary solution. Here we introduce suitable types for our country. 마우나 리조트 붕괴사고, 세월호 침몰사고 등 대형 재난사고들이 발생하였을 때 체계적이지 못한 현장대응과 응급의료시설의 운영으로 인해 재난발생 시 현장에서의 체계적인 응급의료서비스의 필요성이 대두되고 있다. 재난, 재해 발생 시 적절한 시간 내에 안정적인 응급의료서비스가 제공 된다면 2차적인 피해를 줄일 수 있으며 피해에 대한 복구도 신속하게 이루어 질 수 있다. 따라서 다양한 재난의 피해유형과 규모에 맞추어 신속하고 안전하게 재난현장에 대응 할 수 있는 응급의료체계가 구축될 필요가 있다. 이를 위해 현재 국내, 외 사례들을 조사하여 이동 의료단위의 유형을 파악하고, 규모별 분석을 실시한 결과 국외에는 트레일러유형, 텐트유형, 컨테이너유형 등의 이동 의료단위들이 실제 운용되고 있었으며 국내에서는 그러한 운용 사례들을 조사하고 종합하여 정부에 제안하는 단계에 있다. 국내에 적합한 이동형 의료단위의 개발과 제안을 위해 실제운용 사례들의 단위유형, 규모 및 조합적 배치에 대한 심층적인 분석을 토대로 국내에 적절한 유형을 제시한다.

연금개혁 3115: 보험료, 조세재정, 기금의 역할분담을 통한 국민연금의 항구적 재정안정과 노후소득보장 강화

양민규,김우창 한국사회보장학회 2024 사회보장연구 Vol.40 No.1

현재의 국민연금 제도는 기금의 안정성과 소득 보장성의 관점에서 모두 큰 문제점을 내포하고 있다. 추후 GDP 9% 혹은 그 이상까지 상승할 연금급여에 대한 부담이 미래 세대에게 전가되어 세대 간 형평성이 훼손됨은 물론 현재의 충분하지 않은 소득 보장성은 국민연금의 본래 목적인 안정적인 노후 생활조차 보장하지 못하는 결과를 초래할 가능성이 크다. 본 논문에서는 연금개혁을 위한 세 가지 정책변수, 즉 보험료 인상, 기금 운용수익률 개선, 조세재정투입을 활용하여 국민연금 제도에 항구적 재정안정을 부여하고 지급방식 개혁을 통해 소득 보장성을 강화하는 연금개혁 3115를 소개한다. 보험료 3% 인상, GDP 대비 1%의 정부 일반회계재정투입, 그리고 연평균 기금운용 수익률 1.5% 개선의 조합을 통해 기금은 GDP 대비 120% 수준을 유지하며 항구적인 재정 안정성이 확보된다. 또한, 연금급여 지급방식을 완전소득비례로 바꾸되, 투입된 조세재정을 저소득층 및 사각지대에 해당하는 인원들의 보험료 납부에 사용함으로 현재 급여지급방식의 비효율성을 극복하고 절대다수의 가입자에게 공평한 연금을 지급하는 소득 보장성 강화를 달성한다. The National Pension Service (NPS) is currently facing two challenges in financial stability and income security. The total expenditure of NPS is expected to grow up to 9% of nation’s GDP and this will severely damage equity in pension system by imputing the financial burden to the future generations. Also, the benefit from NPS is not enough to ensure old-age income security, which undermines the very reason that NPS was introduced. In this paper, we propose a novel approach for national pension reform, NPS reform 3115, that utilizes three policy variables (contribution rate, NPS fund performance, government budget support) simultaneously to ensure permanent financial stability of the pension system, and that revises the pension benefit distributoin scheme to enhance income security. We show that, by implementing 1) 3% contribution rate increase, 2) government support with a size of 3% of GDP annually, and 3) NPS fund annual average return improvement by 1.5%, the size of NPS fund stays at 120% of GDP, thus we can achieve permanent financial stability of NPS. In addition, we illustrate that, by changing the benefit payment amount fully proportionate to the income level, yet allowing the government budget to cover pension contribution to those who don’t have enough income, old age income security can be much enhanced by providing pension benefits to broad population, as compared to the current “A-value” based pension benefit distribution scheme.
