With the COVID-19 pandemic, more activities are taking place within the home, including working from home and learning from home. In particular, young single-person households face various psychological and physical difficulties as the types and duration of activities in a relatively small house increase. Based on the review of the previous studies on the changed housing behavior of young single-person households during the pandemic and the design proposals for young single-person households proposed in the public housing design competitions, this article proposes three(3) types of the appropriate housing plan for young single-person households in the post-pandemic era.

The world has been establishing policies that consider the environment whereas the construction industry has created and implemented an eco-friendly building evaluation system. In Korea, the mandatory policy of zero-energy buildings has been established since 2020. Overall, awareness and understanding of the Green Standard for Energy & Environmental Design (G-SEED), green architecture, and the environmental certification system are needed. Active House Certification in Europe is a green building certification that has the advantage of being friendly and easy to understand for the public. This study aims to present concepts of environmental certification systems to identify solutions for the active implementation of sustainable features in Korea through the comparison of G-SEED in Korea and Active House Certification in Europe. This study compares, analyzes, and evaluates the evaluation classification system, composition and detailed criteria of Active House certification and G-SEED.

In domestic agricultural products, heavy metals are one of the most important harmful substances together with residual pesticides. The purpose of this study was to investigate the contamination status of 17 agricultural products produced, distributed and sold in Jeonbuk Province in 2016 by investigating the contents of four heavy metals (Pb, Cd, As, Inogarnic As). Agricultural products were analyzed for 248 crops and 17 vegetables. For agricultur80al products, 17 items of cereals and vegetables were analyzed by 248 cases. Microwave method was used for preprocessing and ICP-MS was used. Heavy metals were detected in all samples. In the case of plumbumb(Pb), the mean detectable value was 0.032 for dried bracken, 0.094 for spinach, 0.050 for chestnut sweet potato, 0.023 for soybeans, 0.002 for green chilli, and 0.394 mg/kg for brown rice. Cadmium(Cd) was found to be 0.035 for dried bracken, 0.058 for spinach, 0.041 for potato, 0.024 for red pepper, 0.015 for chinese chive, 0.057 for nonglutinous rice, 0.022 in medicinal plant, 0.077 in brown rice and 0.071 mg/kg in chestnut sweet potato. As for arsenic, nonglutinous rice was 0.041, glutinous rice 0.047, brown rice 0.069, brown rice glutinous rice 0.067 mg/kg. In the case of inorganic arsenic was of 0.033 for nonglutinous rice, 0.070 for brown rice, 0.067 for brown glutinous rice, 0.039 for glutinous rice and 0.090 mg/kg for germinated brown rice showed the results. The samples that exceeded the residual limit of heavy metals (Cd 0.1, Pb 0.2 mg/kg) were 3 brown rice, 0.674 cadmium, 0.337 lead and 0.394 mg/kg lead. All 248 cases were analyzed for harmful heavy metals. Therefore, continuous safety management is required.
혈액가스분석 현장검사기기와 자동혈구분석기 헤모글로빈의 상관성 분석
윤서영,차예지,권오헌,이운형 대한수혈학회 2009 大韓輸血學會誌 Vol.20 No.3
배경: 최근 현장검사기기를 이용한 헤모글로빈 측정으로 수혈을 결정하는 일이 증가하고 있다. 그러나 이러한 현장검사기기의 헤모글로빈 측정에 있어서는 어떠한 가이드라인이나 기준이 명확히 제시된 바가 없는 실정이다. 방법: 혈액가스분석 현장검사기기와 자동혈구분석기의 헤모글로빈 농도를 비교평가 하기 위하여 EDTA와 소듐 헤파린 튜브에 채혈된 40개의 잔여검체를 이용하여 동시에 반복 2회 측정하였다. 결과: 헤모글로빈 농도의 경우 Advia 2120 (x)와 Nova CCX (y)에 대한 회귀분석 결과 기울기는 0.877 (95% confidence interval, 95% CI: 0.826∼0.925), 절편은 2.471 (95% CI: 1.862∼3.059)이었으며, r값은 0.985였다. 임상적 판단 기준값(Clinical decision level)에서의 오차를 계산한 경우 동맥혈현장검사기기의 헤모글로빈 농도는 기대치를 벗어나는 것으로 평가되었다. 결론: 혈액가스분석 현장검사기기는 자동혈구분석기에 비해 헤모글로빈 농도가 높게 측정되는 경향을 나타내었으며, 임상적 판단 기준값에서의 허용범위를 넘는 것으로 나타났다. 혈액가스분석 현장검사기기를 이용한 헤모글로빈 농도의 측정은 그 유용성이 제한적이며, 특별히 수혈의 결정에 있어서는 자동혈구분석기를 통한 헤모글로빈 농도 측정이 중요함을 시사한다. Background: While point-of-care testing is being used increasingly as a basis for making decisions about erythrocyte transfusion, no valid standards or guidelines have been developed concerning the accuracy of measuring hemoglobin concentration. Methods: To compare results from blood gas and auto blood cell count analyzers with respect to hemoglobin, 40 patient blood residual samples which had been withdrawn into 4 mL sodium heparin and EDTA tubes, were analyzed twice by each devices. Results: Passing-Bablok comparisons for hemoglobin (g/dL) with the Nova CCX (y) and Advia 2120 (x) were y=0.877x+2.471 (r=0.985). Additionally, hemoglobin levels from the blood gas analyzer were out of the calculated range at the clinical decision point. Conclusion: Blood gas analyzers as point-of care testing exhibited a slightly higher hemoglobin level than auto blood cell count analyzers. Some also produced values of hemoglobin out of the expected range at the clinical decision point. Therefore, the use of blood gas analyzers for hemoglobin levels is limited and it is recommended that the assessment of hemoglobin for transfusion should be determined using auto blood cell count analyzers.

Background: Health Insurance reimbursement does not accurately reflect the cost of test items performed in a hospital, and it is particularly more difficult to introduce laboratory tests applying new technology. Ensuring the safety of blood bank tests is encumbered since the reimbursement rates for the blood bank items that are high risk are not properly set. In this study, we analyzed the validity of reimbursement through a cost analysis of testing performed in Severance Hospital blood bank. Methods: Original cost and net income were calculated for the tests performed in Severance Hospital blood bank from 1 January, 2009 to 31 December 2009. Results: The original cost and deficit of ABO & Rh(D) blood tests using an automated blood test analyzer was 4,588 won and 1,572 won (52% compared to reimbursement), respectively. Irregular antibody screening test was 3,416 won in original cost and 3,422 won profit. Lewis antigen test was 10,816 won in original cost,creating a 4,745 won deficit. Irregular antibody identification was 32,568 won in original cost and 17,189 won in deficit. Conclusion: Unless the original cost of blood bank tests is reflected in the reimbursement rates, hospital blood banks will run into a budget deficit and blood bank automation, which is used worldwide for patient safety,will not be used in domestic health care. (Korean J Blood Transfus 2010;21:105-114) 배경: 병원현장에서 행해지는 검사항목 중 일부 검사의 건강보험수가는 검사원가를 정확히 반영하지 못하는 항목이 있으며 특히 신기술의료에의한 검사방법이 도입되는 경우 수가 반영이 쉽지 않아 어려움을 겪고 있다. 또한 환자의 안전성측면에서 가장 위험도가 높은 혈액은행 검사 중많은 부분이 적정 수가가 책정되어 있지 못해 의료기관 혈액은행 업무의 안전성 확보에 위협이되고 있는 실정이다. 이에 본 연구에서는 세브란스병원 혈액은행에서 시행하고 있는 검사항목에대한 원가분석을 통하여 현행 혈액은행 검사의보험수가에 대한 타당성을 분석하였다. 방법: 세브란스병원 혈액은행에서 2009년 1월1일부터 2009년 12월 31일까지 시행한 검사항목에 대하여 검사원가와 순이익을 산출하였다. 결과: 자동화 검사로 시행한 ABO와 Rh(D) 혈액형 검사의 원가는 4,588원이며, 건당 1,572 (수가대비 52%)원의 적자를 나타내고 있다. 비예기항체 선별검사는 3,416원의 검사원가로 건당 3,422원의 수익이 생성되었고, Lewis 항원 검사는 10,816원의 검사원가로 건당 4,745원의 적자를 나타내었다. 비예기항체 동정검사는 검사원가 32,568원으로 건당 17,189원의 적자를 나타내었다. 결론: 혈액은행 검사에서 실질적으로 상승한검사원가가 보험수가에는 반영되지 못하면 결국에는 의료기관이 적자구조를 나타나게 되며, 환자의 안전성 측면에서 세계적으로 이용되는 혈액은행 자동화는 국내에 도입될 수 없는 환경이 된다.
