본 연구는 대공간 지붕철골공사의 양중공법 선정을 위한 의사결정지원모델 제안을 목적으로 한다. 이를 위해 이론적 고찰 및 전문가자문을 통해 6개의 상위요인과 19개의 하위요인으로 구성된 양중공법 선정 영향요인을 도출하였다. 이후 AHP분석을 통해 요인별 상대적 중요도를 산정한 결과, 6개의 상위요인 중 현장조건(0.237), 19개의 하위요인 중 여유공지의 유무(0.118)가 양중공법 선정에 있어 가장 중요한 영향요인으로 도출되었다. 이를 바탕으로 현장관리자가 공법대안을 평가할 수 있는 방법 및 절차를 수립하고 최종적으로 현장적합도지수를 제시해줌으로써 의사결정지원모델을 구축을 완료하였다. 구축모델의 검증을 위해 대공간 현장경험자를 대상으로 사례분석을 수행한 결과, 제시된 모델이 공법선정에 있어 유용하게 활용될 수 있을 것으로 판단되었다. 본 연구의 결과는 프로젝트 초기 공법선정 과정에서 현장관리자의 의사결정을 지원하는데 활용될 것으로 기대된다.

The rectifier characteristics and the quality of the input current worsens with the increase of unbalances or harmonics of the supply voltages. Rectifier input current harmonics interfere with proper power system operation, reduce rectifier power factor, and limit the power available from a given source. It is of importance to select appropriately the rectifier's output filter inductance to determine the rectifier input current waveform, the input current harmonics, and the power factor. This paper presents a quantitative analysis of single and three phase rectifier input current harmonics, total harmonic distortion, and power factor as a function of the output filter inductance under balanced and unbalanced conditions. Also, its performance under the supply voltage including harmonics be investigated. These results provide a reference for selecting reasonable rectifier's output filter inductance for given harmonics or power factor criterion.

This study aims to find the main factors to influence consumers' purchase of dairy products. To do so, we examined experts' opinions to verify the priorities of the factors. The four main factors were derived from the previous studies, product factor, marketing factor, quality factor, and social factor. Using analytic hierarchy process (AHP), we empirically analyzed and tested the results from survey. Based on the AHP analysis, the expert group recommended to improve the packaging, brand, and shelf lie of dairy products for the marketing factor, for instance. The results of this study can contribute to the development of the dairy products for the future to reveal the importance of the selecting factors.

FormFactors is one of the most critical design factors in early development of mobile phone, and proper selection of FormFactors is necessary for smoothness of product development and customer satisfaction. Especially, emergence of mobile convergence added so various functions besides its original call function that importance of selecting FormFactors has increased because multiform FormFactors are needed. However there is problem such as frequent change of decision making in existing process because established process picks out FormFactors sensibly and arbitrarily through idea pull and so forth. We proposed FormFactors selection process by Axiomatic Design, set approach method and block approach method for reasonable and systematical FormFactors selection. First of all, we set the purpose of mobile phone development, and it is examined by Axiomatic Design. FormFactors design matrix is deduced through this process, the numbers of axes and rails are proposed using set approach method, and then patterns of FormFactors are embodied by block approach method. Particularly process application was tried through case study of mobile phone development, and we ensured that new FormFactors can be presented to a designer by systematical verification if change of customer requirements occurs through our process.

봉수대는 예로부터 조선시대에 이르기까지 국방 및 통신에서 중요한 역할을 해왔다. 그동안의 봉수대에 대한 연구는 고문헌을 통한 조사에 집중되었다. 본 연구에서는 봉수대 입지 선정에 영향을 주는 요소들인 고도, 단면도, 봉수대간의 거리 및 가시권 등의 지형요소를 분석하였다. 그리고 봉수대의 입지 선정 시 지형적 요소가 어떻게 고려되었는지 분석하였다. 분석 결과 봉수대의 지형 특성은 신호전달에서는 봉수대간의 거리와 가시거리가 상관이 있었고 조망에 있어서는 해안과의 거리와 가시범위가 상관이 있었다. 봉수대의 위치 선정에 있어서는 한가지의 지형요소뿐만 아니라 어려 지형요소들이 복합적으로 고려되었다고 생각된다.

The purpose of this study is to analyze the difference in the degree of self-determination between the criteria that general high school students consider important when selecting subjects (hereinafter referred to as 'importance') and the criteria that are actually applied when selecting subjects (hereinafter referred to as 'implementation'), based on the existing motivation type discrimination scale and subject selection criteria scale. As a result of analysis based on the data of a total of 786 high school students, the degree of self-determination was found to be different for all 34 questions and 8 factors in importance and implementation. In general, the questions and factors showed a simple structure with the motivation types and showed the lowest correlation with the motivations at both ends of the self-determination continuum. Among the factors that students consider important when selecting subjects and the factors that are actually applied, the 'SAT' factor showed the highest positive correlation with identification control. In addition, it was found that autonomous subject selection was more preferred than subject selection based on extrinsic motivation. These results are not only meaningful as the first study to analyze the degree of self-determination in the subject selection of high school students, but also can be used as useful data for customized subject selection guidance according to the degree of self-determination. The implications of this study and suggestions for follow-up studies were discussed.

The purpose of this research is to offer a method to derive the body shapes and pose factors with resets from analyzing factors by using the measurement values of human body. 297 male subjects in their twenties participated in this study. 54 anthropometric and 35 photographic measurements were taken from each subject. Data is the several typical items selected among items and you have to make an index value by using these typical items and convert it. The index has high correlation with each item, is easy to be measured and is to be used after selecting an important item in designing prototype. With results of analyzing reliability level by each item, correlation and items that factor loading is low, the item that the correlation is high is to be removed within the range that maintains the reliability level. Five factors of the front part and seven factors of the profile came to be derived from this kind of process.

The objective of this study was to decide the designing factor for remediaton of the contaminated site. The soil and ground-water samples were analyzed and hydro- geological characteristics was assayed for the survey of pollution level. Also air-permeability test and MPN(most probable number) test were conducted for selecting the designing factor. The contaminants were mainly found in north-west part of the site and were expected to move toward the south. Ex-situ technology was expected more useful than in-situ one with the results of air-permeability test saying that air permeability was relatively low. Additional microbes were expected for remediation efficiency because residual microbes were loosely populated. The choosing of the designing factor was requisite for remediation of contaminated site.

The effect of the dielectric constant (${\varepsilon}$) of bonding materials in screen-printed carbon nanotube cathode on field enhancement factor was investigated using the ANSYS software for high-efficient CNT-cathodes. The field enhancement factor increased with decreasing the dielectric constant and reaching a maximum value when the dielectric constant is 1, the value for a vacuum. This indicates that the best bonding materials for screen-printing CNT cathodes should have a low dielectric constant and this can be used as criteria for selecting bonding materials for use in CNT pastes for high-efficient CNT-cathodes
