The purpose of the study is to demonstrate the lead-lag effect of physical factor and functional factor in urban spatial structure. For investigating the relationship, spatial configuration is selected for physical factor and economical activity for functional factor. Detailed research process and method are as follows. First, space syntax was used to analyze the change of spatial configuration since 1970s. To do this, the l hierarchy of spatial configuration was ranked by global integration analysis of all the districts of Seoul. Second, the change of functional factor of economic activity was analyzed with the annual employment statistics Third, regression and time series analysis were conducted to analyze the time-lag in the lead-lag effect. The regression analysis was done using ArcGIS and looked quantitatively into the correlation between physical factor and functional factor from 1970 to 2010. The analysis found that it, for a period of time, physical factor has an impact on functional factor. Urban spatial configuration has the lead-lag effect on functional factors, by showing the time-lag. This study will provide implications in urban planning and policy guideline.

국내 교통부문 온실가스 총배출량 중 자동차 연료소비에 의한 CO₂ 배출량은 가히 절대적인 비율을 차지하고 있는 것으로 파악된다. 본 연구는 자동차, 그 중에서도 특히 승용차의 주행거리에 영향을 미치는 도시구성요소로서 도로망의 형태 그리고 건물규모와 건물용도의 공간적 배치에 주목하고, 이들 변수를 통해 승용차의 주행거리 및 CO₂ 배출량을 간접 추정하 는 모델을 제안한다. 모델의 개발은 연역적 방식에 의한 수리모델의 구성, 시뮬레이션을 통한 모델 행태의 평가, 그리고 국내 5개 중소도시를 대상으로 한 실제 사례분석을 통해 모델을 조정하는 순으로 진행된다. 연료소비량에 기반한 하향식, 총량적 추정방식과는 대조적으로, 본 연구에서 제안되는 모델은 상향식, 미시적 성격을 갖는 것으로서, 도시구성요소 및 인간활동의 공간적 배치를 다루는 도시계획 및 설계 분야에서 그 활용도가 특히 높을 것으로 기대된다. This paper presents a model to estimate the amount of CO₂ emitted by cars in cities. Based on the spatial configuration of street networks, building masses and usages, it first develops a deductive model to combine them in a way to account for CO₂ emission amount by cars. It then proceed to validate model behaviours through a series of simulations on some ideal urban settings and finally calibrate it following its real application to the five case study cities in Korea. In contrast to the conventional ‘top-down’ approaches, we expect our model to have high utilities, particularly in the field of urban planning and design, where we cannot but deal directly with the spatial configuration of urban components and microscopic human activities.

Operational Mode Summary/Mission Profile(OMS/MP) is a document to quantify the operational and maintenance requirements based on the future operational environments and its mission and How to Fight concept in the development of the weapon system. It is important as a key document for the RAM goal setting in the early phase of weapon system development. The paper presents a systematic and practical submarine OMS/MP model processes with a deep analysis of relevant case studies and current status domestic and abroad. Especially, it proposes the unique Scenario Planning and Switch on List techniques with real case studies which have recently performed. The paper will contribute not only the basis of improved requirements for the development of weapon system but also the sustainment of readiness with the enhancement of RAM and reduction of total life cycle cost.

본 연구는 도시 도로부문에서 발생하는 CO₂ 배출량을 감축하기 위한 노력의 일환으로, 자가용의 통행 및 주행거리에 영향을 미치는 도로망 형태, 건물 규모 및 건물 용도를 설명 변수 삼아 CO₂ 배출량을 추정하는 모델을 제안하고, 이를 국내 23개 중소도시의 CO₂ 배출량 데이터에 근거하여 검증해 보는 시도이다. 분석의 결과 본 연구 모델은 관찰 데이터의 약 79%를 설명할 수 있는 능력을 보였으며, 특히 주행거리와 단위 거리당 CO₂ 배출량을 구분 추정함으로써 도시별 상이한 탄소저감 대응전략을 제시할 수 있는 근거를 마련한 가치를 갖는다고 볼 수 있다.

The purpose of this study is to find out its effect on changes in the joint angle and the success rate of cardiopulmonary resuscitation by conducting cardiopulmonary resuscitation (CPR) when wearing and not wearing PPE (personal protective equipment) targeting 20 paramedics with more than 5 years of experience. The subjects carried out CPR in 30:2 for 4 minutes and collected images were digitized by Kwon3D XP Software Package(Version 4.0) and then data were obtained. Data, which were collected by analyzing the motion when starting in one cycle, when pressing to the maximum, in the final position (relaxed), were analyzed by using SPSS 18.0. In conclusion, during CPR, the angle of the both shoulder joints was not significant (p>.05) and the angle of the right elbow joint was reduced in all positions and was statistically significant (p<.05) and the angle of the left was significantly reduced in the maximum pressure posture and the final position (p>.05). In the case of the trunk, the angle increased statistically significantly at all stages (p<.01, p<.001). Also, during CPR, the average compression rate was significantly reduced after wearing PPE (p<.05) and average hand escape time by cycle increased statistically significantly (p<.05) but chest compression execution rate at the correct depth did not show any significant difference between the two groups (p>05).
