This study was conducted to verify the effectiveness of a combined exercise program to improve the health of the elderly. For this purpose, 10 people in the exercise group and 10 in the control group were selected among seniors aged 65 years or older. The subject of this study was a 12-week combined exercise program in which aerobic and anaerobic exercise were performed three times a week for 60 minutes. Before participating in exercise, blood lipid and inflammatory index tests were conducted, and blood lipid and inflammatory index tests were conducted upon completion of the combined exercise program. The test results were verified with basic statistics and treatment effects between groups using the SPSS statistical program. Based on this, the following conclusions were obtained. First, the combined exercise program for elderly health promotion showed significant differences in TC, LDL, and TG in blood lipids between the exercise group and the control group, and there was an interaction effect on the treatment program. Second, the combined exercise program for improving the health of the elderly showed significant differences in inflammatory indicators IL-6 and TNF-a between the exercise group and the control group, and there was an interaction effect with the treatment program.

Surface-subsurface interactions are an intrinsic component of the hydrologic response within a watershed. In general, these interactions are considered to be one of the most difficult areas of the discipline, particularly for the modeler who intends simulate the dynamic relations between these two major domains of the hydrological cycle. In essence, one major complexity is the spatial and temporal variations in the dynamically interacting system behavior. The proper simulation of these variations requires the need for providing an appropriate coupling mechanism between the surface and subsurface components of the system. In this study, an approach for modelling surface-subsurface flow and transport in a fully intergrated way is presented. The model uses the 2-dimensional diffusion wave equation for sheet surface water flow, and the Boussinesq equation with the Darcy's law and Dupuit-Forchheimer's assumption for variably saturated subsurface water flow. The coupled system of equations governing surface and subsurface flows is discretized using the finite volume method with central differencing in space and the Crank-Nicolson method in time. The interactions between surface and subsurface flows are considered mass balance based on the continuity conditions of pressure head and exchange flux. The major module consists of four sub-module (SUBFA, SFA, IA and NS module) is developed.

National Innovative Capability (NIC) is an important decisive factor where economic growth is concerned. As such, it is very important to measure and manage NIC. The composite index approach is one of the widely used approaches to measuring NIC, but there have been insufficient reviews of its feasibility and reliability. This paper conducted an analysis of the feasibility and reliability of the report on the last three years (i.e. 2011 through 2013) of the Innovation Union Scoreboard (IUS) of the EU, which is the most representative means of measuring NIC. It turned out that its reliability meets the recommended criteria as a result of Chronbach's alpha-based test of the models of IUS-related composite index. However, neither the absolute fit index nor the incremental fit index was found to meet the recommended criteria in a construct validity analysis. It also turned out that predictive validity is very low as a result of panel linear regression analysis of sectors and items of IUS-related composite index. This paper presents a number of considerations to be made when measuring national innovative capability using the composite index approach, as well as major policy suggestions based on the results of the analysis.

The purpose of this study was the effect of complex training of obese men in their 30s on inflammatory markers and homocysteine, a risk factor for cardiovascular disease. The subjects consisted of obese men (n=12) with the body fat ratio of 25% or above in their mid 30s who had no medical conditions and can follow the exercise routine required by this study. To achieve the purpose of this study measured the maximum oxygen intake (VO_2max) and 1RM of 5 kinds of machine(bench press, lat pull down, arm curl, leg press, squat) as a preliminary test; based on the results, performed 8 weeks complex training (aerobic exercise + weight training); and then analyzed the variation in body composition (body weight, body fat and BMI), blood inflammatory markers (IL-6, TNF-α and CRP), and homocysteine between before and after training. The results exhibited that 8 weeks complex training reduced weight, body fat and BMI significantly (p<0.01) and also reduced inflammatory marker CRP and homocysteine, a risk factor for cardiovascular disease, significantly (p<0.05). In conclusion, 8 weeks complex training confirmed the variation in body composition, and this variation has a positive effect on the inflammatory marker and the risk factor for cardiovascular disease.

최근 기후변화 때문에 태풍, 호우 등 자연재해로 수방시설물의 피해규모가 커지고 있으며 이러한 피해는 단일 재해요인이 아닌 여러 재해요인이 복합적으로 작용하여 발생하고 있다. 그러므로 도시의 안전성과 방재기능을 확보하기 위해서는 복합위험요소를 고려한 재해위험도의 진단 기술 및 종합적인 재해경감대책 수립을 위한 연구가 필요한 실정이다. 복합위험요소를 고려한 재해위험도 및 재해경감대책을 수립하기 위해서는 도시재해를 유발하는 다양한 요인들이 도시재해에 미치는 영향과 재해요인 중에서 어떠한 재해요인이 도시재해에 더 큰 영향을 미치는지에 대한 검토가 필요하다. 이에 본 연구에서는 정보전달 이론 중의 하나인 엔트로피 방법을 이용하여 복합위험요소를 고려하여 도시지역에 대한 재해위험도를 나타내는 복합위험지수의 가중치를 산정하고자 하였다. 복합위험지수의 가중치는 지표별 속성정보를 추출하여 정규화 과정을 거친 후, 속성별 엔트로피를 산정하여 지표별로 산정된다. 엔트로피 방법에 따라 산정된 가중치는 다른 가중치 산정 방법에 따라 산정된 가중치와의 비교 분석을 통하여 타당성을 검토할 것이며, 이렇게 산정된 가중치를 복합위험지수 산정에 적용한다면, 보다 현실성 있는 도시재해 위험성 또는 취약성 지수로 활용될 수 있을 것으로 판단된다.

In order to diagnose cardiovascular disease, we proposed EP-based(emerging pattern- based) classification technique using multi-parametric diagnosis indexes. We analyzed linear/nonlinear features of HRV for three recumbent postures and extracted four diagnosis indexes from ST-segments to apply the multi-parametric diagnosis indexes. In this paper, classification model using essential emerging patterns for diagnosing disease was applied. This classification technique discovers disease patterns of patient group and these emerging patterns are frequent in patients with cardiovascular disease but are not frequent in the normal group. To evaluate proposed classification algorithm, 120 patients with AP (angina pectrois), 13 patients with ACS(acute coronary syndrome) and 128 normal people data were used. As a result of classification, when multi-parametric indexes were used, the percent accuracy in classifying three groups was turned out to be about 88.3%.

본 연구에서는 복합금융그룹의 부실위험을 그룹전체기반 측도로 측정하는 방법론을 비교하고 국내 복합금융그룹의 자료를 이용하여 실증분석한다. Joint Forum(2001a) 방법은 연결기준을 사용하여 그룹내 자본의 중복요소들을 상계한 후 필요자본 대비 자기자본비율을 구한다. 신BIS 규제자본 방법은 Vasicek(1987)의 점근적 단일위험 모형을 가정하여 자산의 전체기반 위험을 측정하고 연결기준을 사용하여 자본의 중복계상을 배제하여 측정한다. 개별 경제적 자본 방법은 개별 경제적 위험을 수준별로 합산하여 전체기반 경제적 자본을 빌딩블록 방식으로 합산한다. 경제적 자본 방법은 위험 측정시 겪게 되는 극단적 손실 문제와 결합분포의 비대칭성을 반영할 수 있는 방법을 측정시 포함시킬 수 있다. 국내 복합금융그룹의 자료를 이용하여 실증분석을 한 결과, 첫째, 개별 재무지표에서 복합금융그룹 소속회사들의 ROA, ROA 변동성 그리고 총자산 대비 자기자본비율이 우량한 것으로 나타났다. 특히 가장 비중이 큰 은행산업에서 위 개별 재무지표는 복합금융그룹 소속회사에서 우량하게 나타난다. 둘째, 그룹전체기반 위험자본 측도로서 필요자본 대비 자기자본 비율과 연결기준 BIS비율을 살펴본 결과 은행계열 금융그룹의 부실위험이 낮은 것으로 판단된다. 전체적으로 국내 복합금융그룹의 부실위험은 높지 않은 것으로 판단된다. 이상의 결과를 바탕으로 복합금융그룹에 대한 리스크상시감시방안에의 시사점을 살펴보면, 첫째, 복합금융그룹 소속 금융회사에 대한 리스크 평가시 그룹전체기반 부실위험평가를 반영하여 이를 측정할 필요가 있다. 둘째, 권역별로 통일된 리스크감시를 위해 권역별 자기자본규제의 형평성을 제고할 필요가 있다.

Recently, several number of Multi-Intermodal Transfer Center are nominated to improve convenience of public transportation user. Due to budget constraints, it should be defined which is the first consideration among the discussed many works. In this circumstance, there are some absurdities in the evaluation of validity of existing methods. Therefore, we suggested the Priority Order Valuation for Multi-Intermodal Transfer Centerer. The evaluation method, we suggested, is considered quantitative analysis and qualitative analysis. In this study, we find out that B/C ratio and construction costs are strongly related to the quantitative analysis so that Multi-Intermodal Transfer Centers in metropolitan area are evaluated the positive results. Therefore, both quantitative analysis and qualitative analysis are applied to the Priority Order, metropolitan area and other area are fairly evaluated the results for the Priority Order.
