오늘날 고령인구의 증가와 장애인 인구의 증가로 인해 재활훈련기의 수요가 증가하고 있고, 재활훈련기와 사용자간의 제공받아야 할 서비스에 대한 평가 요소의 요구가 커지고 있다. 본 연구에서는 재활훈련기 디자인 평가에 있어서 평가 방안을 모색하기 위해 디자인 평가를 위한 기본 요소를 파악하고 이를 통하여 재활의료전문가, 의공학자, 디자이너들의 토의 및 분석, 실험을 통하여 새로운 평가 요소들을 도출하였다. 연구의 결과는 다음과 같이 요약된다. 첫째, 기존 디자인 평가 요소들을 수집, 분석하여 10가지의 재활훈련기 디자인 평가요소와 44개의 세부 평가항목을 구축하였다. 이는 앞으로 재활훈련기를 디자인하는데 있어서 중요한 평가 기준이 될 것이다. 둘째, 헬스케어 재활훈련기 디자인 개발 시 고려해야 할 디자인 평가요소로는 사용성, 인지성, 안전성, 학습성, 운동성, 내구성, 경제성, 공간성, 심미성, 환경성의 10가지 디자인 평가요소가 있다. 셋째, 환경성, 공간성, 인지성, 사용성, 경제성, 심미성의 디자인 평가요소는 제품디자인에서 공통적으로 고려해야 할 요소들이고, 학습성, 안전성, 운동성, 내구성의 요소는 재활훈련기 디자인 평가요소에서 매우 중요하게 고려해야 할 요소이다. 넷째, 재활훈련기 디자인 평가요소는 제품디자인요소에서 중요하게 고려되는 환경성, 공간성, 인지성, 사용성, 경제성, 심미성에 학습성, 안전성, 운동성, 내구성을 의 요소를 더해 중요하게 생각한 것이 기존 제품디자인 평가요소와 재활훈련기 디자인 평가요소의 차이점이다. 본 연구에서는 10개의 재활훈련기 디자인 평가요소와 44개의 세부 평가항목 구축에 대한 연구를 진행하였다. 이는 전체적인 재활훈련기 디자인 평가요소만을 연구한 것으로, 향후연구에서는 시 제품 제작을 통하여 평가요소들을 실제 재활훈련기 디자인에 적용해 보고, 미진한 점들을 수정 보완할 예정이다.

Korean government is planning to supply a half million public and permanent rental houses from 2013 to 2018 for settlement of non-homeowners. It is requested an objective criterion to appropriate the budget for the rental houses construction project cost. In this study, construction cost indices, which reflect the inflation trend of construction resources, were explorated to suggest a effective methodology for the construction cost estimation of therental houses. We figured out the future construction cost indices using several scientific methods, and seven estimated indices values were shown. It is required an additional research to select the proper value among the analyzed indices.

This paper examines the persistence of relative consumer price indices for 15 regions in Korea including 6 metropolitan cities and 9 provinces over the period of 1990-2016. In particular, we ask if relative regional price indices contain a common stochastic trend and find that they are not. We then investigate how quickly these relative prices converge to their long run value and find that a half-life of a deviation from the long run value is in the range of 13 to 22 months for the aggregate consumer price indices and in the range of 7 to 13 months for the tradable goods price indices, which is much quicker than the estimates of previous studies. These estimates suggest that existing monetary models with the realistic duration of price rigidities can generate the persistence in relative price indices.

As we know, some indices and data are strong influence to the price movement of some assets now, but not to another assets and in future. Thus we define some asset models for several time intervals; intraday, weekly, monthly, and yearly asset models. We define these asset models by using Brownian motion with volatility and Poisson process, and several deterministic functions(index function, twitter data function and big-jump simple function etc). In our asset models, these deterministic functions are the positive or negative levels of auxiliary indices, of analyzed data, and for imminent and extreme state(for example, financial shock or the highest popularity in the market). These functions determined by indices, twitter data and shocking news are a kind of one of speciality of our asset models. For reasonableness of our asset models, we introduce several real data, figurers and tables, and simulations. Perhaps from our asset models, for short-term or long-term investment, we can classify and reference many kinds of usual auxiliary indices, information and data.

A graphical method to determine the anthropometric levels that's are lean, slightly lean, normal, slightly obese, obese by BMI, Broca and Rohrer indices was developed. On the graph of height vs. weight, regions corresponding to the anthropometric levels were separated by equations calculated with boundary conditions for BMI, Broca and Rohrer indices, respectivelyl. It was observed that the determinations of the anthropometric level was influenced by the weight to a larger extent than the hight, which magnitude was in the order of BMI>Broca>Rohrer. There appeared significant differences between the results of the anthropometric level for higher and weight by BMI, Broca and Rohrer indices, respectively. Conclusively, the graphical method was proved as a good means to analyze and compare the anthropometric levels from BMI, Broca and Rohrer indices.

Most of agricultural reservoirs in Korea have no function of flood control except 5% of reservoirs even exposed to natural disaster. In addition, there are increasing needs for the reservoir to guarantee the release of environmental flow to the downstream. Thus, the purpose of this paper is to study the priority decision method for the reservoir redevelopment satisfying both water utilization and flood control. The major scopes of this research are to set up six priority indices and to make needed GIS data for calculating each priority. There is important consideration of obtaining the data or not in deciding the indices. Although the detailed indices is expected to better reflect redevelopment priority but the subjective indices like, 'opinion' and 'landscape' are excluded. From the results, it will enables the six priority indices to really assist in decision redevelopment priority of agricultural reservoirs.

In this study, paying much attention to notable features obtained from spatial distributions of strongly related indices (precipitable water, convergence of air, convective available potential energy) with precipitation, fatal problems in selecting strongly related indices with observed precipitation in a BAIU season were discussed. These results showed spatial distribution of a predicted index provided alternative and physically consistent interpretation for selecting dominant index for heavy rainfall even if the predicted index did not correlate with observed rainfall at a specific observational point as confirmed by the features of CONV (Convergence) or even if it correlated with observed rainfall as confirmed by those of PW (Precipitable Water). Therefore, dominant meteorological indices of heavy rainfall should be selected according to physically evidenced interpretation on features of spatial distributions of indices, and physically and statistically consistent relationship should be built up.

This study is to find some clues about background or causes of the mass supply of apartments in Korea in terms of correlation analysis using 30 indices extracted from the representative housing statistics data. Some findings include that the supply ratio of apartments is deeply related to 'average floor area ratio' and 'the construction amount of Dagagu housing and Dasedae housing' from the perspective of housing flow. Instead, from the perspective of housing stock, the supply amount of apartments is strongly related to 'housing redevelopment construction' and 'housing construction by public sector'. These indices are involved deeply in the spread of apartments, however, because the indices that used in the analysis are mutually highly related and the indices related to housing policy or system are absent, a critical index for the spread of apartments was not found.

The purpose of this study was to extract information of body form's classification on elderly women. We measured 242 subjects from 55 to 75 years of age, using 27 direct measurement items and 25 body indices. We analyzed these indices with factor analysis, cluster analysis We obtained these following results 1) Through factor analysis, 4 factors (obesity of torso, location of upper torso items, length of upper torso, location of lower torso items & shoulder length) were extracted from body indices. 2) Through culster analysis, we categorized 4 clusters. Namely, type 1, characterized the best slender type, type 2; characterized obesity type, type 3: characterized middle sized type ; type 4: characterized by fat type less than type 2. We considered that type 3 is the typical type on elderly women. Since analysis using indices is very profitable, it may be necessary to design dummies and patterns for clothing manufacture.

The present paper describes the slagging field data obtained with the one-dimensional process model for the 500 MW tangentially coal fired boiler in Korea. To obtain slagging field data in terms of thermal resistances [$m^2{\cdot}^{\circ}C/kW$], a number of plant data were collected and analyzed with the one-dimensional modelling software at 500 MW full load. The slagging field data for the primary superheater were obtained for six coal blends, and compared with two TMA (Thermo-Mechanical analyzer) slagging indices and the numerical slagging index, along with the conventional slagging indices which were modified with the ash loading. The advanced two TMA indices for six blended coals give a good slagging tendency when comparing them with the slagging field data, while the modified conventional slagging indices give a relatively poor agreement.
