As the scale of telecommunication market extremely increases, the competition to attract consumers is being intensive among telecommunication companies. Domestic telecommunication companies try to attract consumers by better quality and service to enhance satisfaction. The scientific research to evaluate satisfaction factors and total contentment about telecommunication companies is necessary for enhancing competitiveness and added value. In this paper, we study and analyze the way to estimate the satisfaction by AHP and statistical method. Consumers will receive good quality products and service by using suggested method. Additionally, domestic telecommunication expects to ensure competitiveness globally.

본 논문에서는 비점원오염 관리를 위한 지역선정을 위하여 계층분석적 의사결정기법에 의한 접근 방법을 제시하였다. 주어진 유역 내에서의 비점원오염의 중요기여 인자간의 관계를 반영한 것이 본 연구의 특징이다. 주요인자로는 경사도, 유달거리, 유효강우비, 불투수면적비, 토양유실량이다. 각 인자의 가중치는 계층분석적 의사결정기법(AHP)으로 구하였으며 각 인자의 가중값과 속성 값의 단순 부가가중 합으로 표현되는 비점원오염 영향지수를 정의하였다. 높은 영향지수를 가지는 지역을 비점원오염 관리지역으로 제안하였으며, 시험유역으로 발안HP#6유역을 선정하여 적용해보았다. 관리지역 결과를 비교하기 위하여 AGNPS 모의를 통한 비점원오염 부하량간의 분석을 시도하였다. 비교 및 분석을 위해 Moran's I를 이용하였으며, T-N은 $0.38{\sim}0.45$, T-P는 $0.15{\sim}0.22$의 범위를 보였다. 이는 두 접근 방법이 상이함에도 공간적으로 유사한 경향을 보인다는 것을 말한다. 본 연구에서 제시하는 방법은 비점원오염 관리지역 선정에 있어서 적용가능 함을 의미한다.

To visualize a strategic plan including resource allocations and standardization schedules, it is important to set priorities among information and communication technologies(ICTs) standardization work areas(SWAs). This ranking process involves decision making process with multiple criteria which results a complex selection problem. In this study, analytic hierarchy process(AHP) is employed and applied to solve this decision making problem. The processes and results are illustrated for an effective strategic plan in standardization decision processes.

This study introduces an objective and systematic framework for prioritizing buildings in the Gamyoung restoration project using a decision-support model. This model integrates evaluation criteria derived from a comprehensive literature review, refined through the Delphi method, and weights assigned via an Analytic Hierarchy Process(AHP) survey. Each building project is scored against these criteria to ascertain its priority for restoration, thereby facilitating informed decision-making for budget allocation in restoration projects. The effectiveness of the decision-support model was validated through a case study and expert consultations, demonstrating its practical utility in formulating concrete restoration project plans.

본 연구에서는 기존문헌에서 논의되어온 수리적 매체선택모형의 한계점을 고려하여 의사결정자에게 유용한 매체선택지침을 제공할 수 있는 모형을 구축하고 이를 실제사례에 적용하여 모형의 현실적용성을 살펴본다. 기존의 매체선택모형들은 가정의 현실성 결여와 특정 요인의 단편적 고려 등으로 인하여 실행상의 문제점을 노출하였다. 최근 매체의 이미지, 소비자에 대한 소구, 편집항목 등 매체현상과 관련된 정성적 요소들을 고려하고자 하는 의도에서 AHP를 매체선택 문제에 활용하고 있으며 이것은 매체선택모형을 보다 현실적인 모형으로 만들고 있다. 또한 AHP에 의해 도출된 매체의 선호정도를 독립적으로 이용하는 것보다 정량적인 요소를 고려한 수리적 모형과 결합하는 것이 보다 효과적인 것으로 이해되고 있으며 이는 매체선택모형의 현실적합성을 한층 증가시키고 있다고 할 수 있다. 이러한 정성적 요소와 정량적 요소를 결합한 매체선택모형은 다양한 의사결정요소들을 모형에 포함시켰다는 의미에서 기존의 모형들과 차별화가 이루어지나 실제 모형을 적용하여 그 효과를 판단하는 것은 광고의 복잡성과 측정상의 문제로 인해서 매우 어려운 일로 보인다. 따라서 매체선택 모형은 더 이상 장량적인 관점에서 최적해를 추구하기 보다는 모형이 광고의 상황과 기업의 전략등에 얼마나 효과적으로 대처하는가에 초점을 맞추는 것이 중요하다. 이에 따라 본 연구에서는 AHP와 정수계획법을 결합한 모형을 이용하여 고려하고자하는 매체선택 관련요소들을 체계화하고 이 모형이 최적해를 산출하는 모형으로서가 아니라 의사결정자에게 매체선택지침을 제시하는 하나의 현실적인 의사결정지원도구로서 역할을 하고 있는가에 초점을 맞춘다. (4) 교수-학생간의 인간적인 관계, (5) 숙제 및 과제물과 같은 5가지의 요인으로 구성되어진 것으로 분석되었다. 특히 한국학생을 대상으로 하여 AHP를 이용하여 각 요인들의 수업효과에 대한 상대적 가중치를 조사하였다. 특이한 결과는, 미국학생의 경우 수업준비 및 강의 방법이 상대적으로 중시된 반면, 한국학생들은 미국학생들이 비교적 덜 중시하는 교수-학생간의 인간적인 관계가 수업효과를 높이는데 가장 큰 기여를 하는 것으로 나타났다. 본 연구는 한국 문화의 특징이라 할 수 있는 교수-학생간의 인간적인 관계가 중시되는 교육환경하에서, 정보화 사회의 한 수업형태인 재택수업을 외국(특히 미국)의 방법을 그대로 따라 실시할 경우, 많은 부작용이 있을 수 있다는 것을 암시하며, 따라서 우리 교육문화에 맞는 재택수업 형태의 개발이 시급함을 제시한다고 하겠다.column density of HCaN is (1-3):n1014cm-2. Column density at distant position from MD5 is larger than that in the (:entral region. We have deduced that this hot-core has a mass of 10sR1 which i:s about an order of magnitude larger those obtained by previous studies.previous studies.업순서들의 상관관계를 고려하여 보다 개선된 해를 구하기 위한 연구가 요구된다. 또한, 준비작업비용을 발생시키는 작업장의 작업순서결정에 대해서도 연구를 행하여, 보완작업비용과 준비비용을 고려한 GMMAL 작업순서문제를

The modern society has been drastically changed from the industrial economic society to the knowledge based society, to catch up with the knowledge and the change of technology required for the modern people, the people can not live in the modern society without the continued study or education. In case of architectural design firm, it is concentrating on the productivity of enterprise by cultivating the working level through the self education focused on the improvement of inner capacity. In connection with this, the efficiency of enterprises are analyzed by carrying out the Data Envelopment Analysis(DEA) utilizing the financial ratio index in the various field of industries recently, the analysis study for the efficiency utilizing DEA is increased in the construction industries as well. However, in case of construction industries, the study focused on the efficiency of administration only has been progressed, it is the real situation that the approach for the analysis of education efficiency of each enterprise is very insufficient. Therefore, this study analyzed the education efficiency of architectural design firm after the selection of input and output variables by utilizing the DEA model and utilizing the AHP analysis technique by deducting the variables through the preceding study in relation to the education efficiency and the interview with the specialists.

The dissertation presents the portfolio construction method using the score sheet so that general investors can utilize it easily. This study draws the significant variables to contribute the enterprise value and suggests the combined models by applying the single methodology, which private investors can easily utilize. The results of the research can be classified into 2 areas. Firstly, the significantly affecting variables were selected for analyzing the enterprise value. The variables and the method for the enterprise value analysis were studied from the existing researches to choose the optimal variables. The variables were identified by using AHP method and the structure equation method from the investigation of the previous researches. And the critical variables were added extracted from the common denominator of variables which the 3 grue investors used for their investment. The final variables identified are dividend yield, PER, PBR, PCR, EV/EBITDA, ROE, net income, sales growth rate, net current asset, debt ratio, current ratio, rate of operating profits, ratio of operating profit to net sales, ratio of net income to net sales, net profit to total assets, EPS growth rate, inventory turnover ratio, and receivables turnover. Second, the new methodologies for forecasting enterprise value modifying the existing methods were developed. The result of the Logistic regression analysis for forecasting showed that the equation could not be suitable as the accuracy with 91.98%.

This paper aims to presents a systematic procedure for the development of construction technology roadmap, which can consider the offshore wind farm on port. Then the weight among the large/medium/small classified construction technology has identified through the AHP(Analytical Hierarchy Process) approach using FGI(Focus Group Interview) and questionnaire study. Based on the priority for classified construction technology a construction technology roadmap for port offshore wind farm was also developed. The technology roadmap suggests the time frame(20 years, from 2016 to 2036) to complete R&D work for the classified construction technology of port offshore wind farm. Such construction technology roadmap can be utilized as a milestone in setting up the R&D strategy in the green port construction industry.
