최근 선진국에서는 지역사회의 지역특성, 대비능력 등을 토대로 맞춤형 재난 대비책을 마련하여 시행하고 있다. 이는 중앙정부의 한정된 자원을 효율적으로 배분하고, 지방정부는 지역의 취약성을 파악하여 구체적 적응정책의 방향성 제시를 가능하게 한다. 우리나라 역시 재해위험에 대한 각 지역의 방재능력을 여러 가지 방법으로 진단하고 있으나 대부분 지역의 인구, 재정력, 시설, 인력, 자원 확보 및 계획 등 정량적 정보만을 종합하여 위험도를 진단하고 있어 재해위험에 대한 지역민과 지역사회가 느끼는 취약성을 제대로 반영하지 못하고 있는 실정이다. 이에 본 연구에서는 홍수 취약성 개념 틀을 정의하고 지역사회를 기반으로 취약성을 평가할 수 있는 홍수피해저감지수(Flood Disaster Risk Reduction Index, FDRRI)를 개발하였다. FDRRI는 지형적 기상적 요인을 고려한 홍수노출지표, 사회적요인과 과거피해 요인을 고려한 민감도지표, 지역안전도 피해저감능력지수를 고려한 피해저감능력지표, 지역민의 대비능력을 나타내는 지역사회대비능력 지표를 결합하여 평가된다. 특히, 지역사회대비능력지표는 지역민 설문조사를 통해 지역민의 역량을 정량화한 것으로 본 연구에서 처음으로 도입한 것이다. FDRRI의 적용성 검토를 위해 지형적 특성, 홍수피해정도 등을 고려하여 낙동강 유역의 경북 봉화, 김천, 경남 고성, 김해를 시범지역으로 선정하고 FDRRI를 산정하였으며 타당성을 검증하였다. FDRRI는 홍수위험에 대한 지역의 저감능력을 잘 반영하고 있으며, 지역별 맞춤형 저감대책 및 지역사회가 참여한 지속가능한 재난관리 정책 수립 등에 활용될 수 있을 것으로 기대된다.

Hemorrhagic shock is a clinically widespread syndrome characterized by inadequate oxygenation and supply. It is important to diagnose hemorrhagic shock in its early stage for improving treatment effects and survival rate. However, an accurate diagnosis and treatment could be delayed in the early stage of hemorrhagic shock by evaluating only vital signs such as heart rate and blood pressure. There have been many studies for the early diagnosis of hemorrhagic shock, reporting that lactate concentration and perfusion were useful variables for tissue hypoxia and metabolic acidosis. In this study, we measured both perfusion using a laser Doppler flowmeter and lactate concentration from the volume controlled hemorrhagic shock using rats. We also proposed a new shock index which was calculated by dividing lactate concentration by perfusion for early diagnosis. As a result of the survival prediction by the proposed index with the receiver operating characteristic curve method, the sensitivity, specificity, and accuracy of survival were 90.0, 96.7 and 94.0%, respectively. The proposed index showed the fastest significant difference among the other parameters such as blood pressure and heart rate. It could offer early diagnosis and effective treatment for human hemorrhagic shock if it is applicable to humans.

정부는 공공데이터 개방을 통해 신산업, 일자리 창출 등 경제 활성화를 위한 도구로 활용하는 것을 목표로 한다. 정부는 고품질의 공공데이터 보유를 위하여 품질 개선 활동을 통해 공공데이터 품질 향상을 진행하고 있다. 그러나 공공데이터 품질관리 수준 진단을 진행하는 담당자의 데이터에 대한 전문성과 이해도에 따라 품질진단 결과에 격차가 발생하여 진단 결과의 신뢰성을 보장하기 어렵다. 본 논문은 공공데이터의 원활한 품질진단 지원을 위해 품질진단규칙 매핑 모델을 제안하여 공공데이터 품질진단의 안정성과 신뢰성을 높인다.

This study started with many experiences about maturity evaluation and efficiency improvement of Project Management information system, and need for IT systems for performing of strategy. The objective of this study is 1)to evaluate processes and IT systems based on CSF in strategy perform phase, 2)to propose method of sustainable evaluation and improvement, and 3)with KPI and CSF, to evaluate and improve PMIS. Moreover, we suggested IT architecture framework for basement of improving process and resources.

Objectives Recent studies have reported that the digestion-related items contribute significantly to the diagnosis of constitution, though these were not described as the indicator for diagnosing Sasang constitution in 『Donguisusebowon(東醫壽世保元)』 「Sasanginbyeonjeunglon(四象人辨證論)」. The purpose of this study was to explore the reasons why such a gap appeared. Methods The digestion-related items and their rationales to be shown in eleven studies on the Questionnaire for Sasang Constitution Diagnosis were reviewed. Thirty primary studies included in two systematic reviews were also reviewed to reconsider the significance of digestion-related items as an indicator for diagnosing Soeumin. Results & Conclusions A few pathways were found in studies on the Questionnaire for Sasang Constitution Diagnosis, which could overestimate the significance of digestion-related items more than actual. Besides, in the primary studies included in two systematic reviews, there was also a possibility of overestimating the importance of digestion-related items due to some biases in the selection of subjects and the conducting of the study. Therefore, there might be room for reconsideration that indigestion was necessarily an indicator for diagnosing Soeumin.

인체의 흉부 X-ray 영상으로부터 척추질환과 관련된 의료 진단지표를 자동으로 추출하는 과정을 위하여 흉추조직의 정확한 분할이 필요하다. 본 연구에서는 HRNet 기반의 학습을 통하여 흉추조직을 분할하는 방법을 고찰한다. 분할 과정에서 영상 내의 상대적인 위치 정보가 효과적으로 반영될 수 있도록, 계층별로 영상의 고해상도의 표현이 그대로 유지되는 구조와 저해상도의 특징 지도로 변환되는 구조가 병렬적으로 연결되는 형태의 심층 신경망 모델을 채택하였다. 흉부 X-ray 영상에서 콥각도(Cobb's angle)를 산출하는 문제를 대상으로 흉추 분할을 위한 학습 방법, 진단지표 추출 방법 등을 소개하며, 부수적으로 피사체의 위치 변화 및 크기 변화 등에 강인한 성능을 제공하기 위하여 학습 데이터를 증강하는 방법론을 제시하였다. 총 145개의 영상을 사용한 실험을 통하여 제안된 이론의 타당성을 평가하였다.

The purpose of this paper is to suggest a scientific evaluation criteria for integration of person with disabilities by developing and measuring the index and indicator of disability integration. Disability integration index will be expressed in a simple number to represent the current situation which will summarize the level of integration of persons with disabilities from the perspective of outcome. Disability integration index is composed of four indicators-social attitude toward person disability, physical environment, participation in society expressed by employment and education, and social institution. Observation research was conducted to measure first two indicators of social attitude and physical environment while existing statistics and data were analyzed for other two of participation in society and social institution. The result of this study showed that disability integration index of Korea was 0.4832. Therefore this paper comes to conclude that the level of integration in Korea approaches to 48 percent which is half of ideal integration. However, this study has its limitations in selection of indicators and index formula which in turn must be followed by next studies.

In Republic of Korea, there are considerable vulnerability in electrical stimulating swallowing-assist equipments even though they are professional medical equipments and have high penetration rate with heavy frequency of use. Therefore, in this article, we developed Device Management and Safety Diagnosis Manual for Electrical Stimulating Swallowing-Assist Equipments system. For achieving this, we collected and analysed international standard data from international organizations like International Electrotechnical Commission(IEC). After literature reviews, we build maintenance worksheet and equipment procedure manual for electrical stimulating swallowing-assist equipments according to evidences we collected. These manual and protocol would be used as standard process and contribute to sustain accuracy, effectiveness of the devices, also decrease failure rate and assist to save medical documents.

The pursuit of strategic infomatization plays a critical role in increasing the competitiveness of domestic companies in this rapidly changing era. In particular, infomatization of small and medium construction companies is lower than that of large companies in terms of company size and the range of infomatization. Also, the environment for the infomatization is very unfavorable. Thus, to ensure effective infomatization of small and medium construction companies, it is critical to assess the current level of infomatization, and ensuing initiatives should start by gaining an accurate understanding of the level that should be reached in the future by each stage. This paper purports to develop indices which are needed for the diagnosis of current level of infomatization and for the understanding of current realities, problems and requirements that the small and medium construction companies face while pursuing infomatization today.
