The purpose of this study is to devise the overall problems (such as, rights and obligations between users, owners, managers regarding commercial rental buildings, benefit/benefit in return, and the relevant regulations and systems) of the building maintenance system through field surveys, expert interviews, and literature reviews. In this rapidly changing society, there are a huge amount of needs for various reforms which can meet the diversity in each area, so it is greatly important to choose priority for the best improvement for efficient and economic expenses due to limited time, human resources and budgets. In this regard, the study extracted the evaluation elements from the devised problems with the viewpoint of BSC, calculated the weights through application of AHP to the extracted evaluation elements, evaluated the difference between before/after application of weights, and set the status, which makes it possible to realize the effective solutions and the reasonable expenses for all parties. By doing so, it is expected that the building maintenance system which maximizes the value and guarantees the user's convenience with smart functions of the building, will be realized in the near future.

Recently, with the increase of high rise and huge scale building construction, the use of high strength concrete has been increasing. High strength concrete has dense pore structure, which is susceptible to be damaged due to fire attack. For this, many researchers provide proper fire endurance method. In this paper, to provide the priority for selecting fire endurance method in high strength concrete execution, AHP technique is applied based on expert questionnaire. Fire endurance performance efficiency and ordinary performance efficiency was selected for level 1. Fire endurance performance efficiency had larger weight than ordinary one.

IT 자원의 상호운용성 및 재활용성 등의 장점 통하여 새로운 비즈니스 환경변화에 가장 빠르게 대응할 수 있는 최적의 대안으로 서비스 지향 아키텍처(SOA : Service Oriented Architecture)가 최근 각광받고 있다. 그러나 구현의 복잡성 및 그에 따른 낮은 ROI(Return on Investment) 평가와 같은 SOA의 문제점들을 보완하기 위해 웹 지향 아키텍처(WOA: Web Oriented Architecture)가 제안되었다. 하지만 WOA 또한 보안 및 안정적인 메시지 전달 등의 문제점들을 안고 있다. 본 논문에서는 SOA와 WOA 구현의 핵심 개념을 연구하고, SOA 또는 WOA를 이용하여 서비스를 구현할 경우 중요한 핵심 개념의 복잡도를 AHP(Analytic Hierarchy Process) 기법을 통하여 평가하였다. 이를 통하여 SOA 또는 WOA 구현 시 요구되는 핵심 요구사항의 중요도를 평가하고 개발자에게 미치는 구현 복잡도를 측정할 수 있다.

AHP 기법을 통해 도출된 결과에 대하여 개별 계산 방법과 그룹 계산 방법을 통해 정확성을 검증하였다. 일반적으로 AHP 기법을 사용하여 가중치를 도출하지만 일관성 확인은 되지만 결과 값의 검증은 하지 못하고 있다. 본 연구에서는 이러한 문제점을 엑셀을 통해 확인하는 과정을 제시하였다.

To develop of a new software, software development methodology is offering the most efficient development methods and management methods. But, it require a lot of time, cost and software engineering specialist. For this reason, we are awaking to the need of it, but it has its problem that is only applied to large-scale software. In this paper, we suggest optimized software development methodology that you can apply to a lot well-used small software development methodology in present, and we prove it through AHP(Analytic Hierarchy Process). This helps small and business not to introduce specialist can efficiently develop and manage software.

In today's IT environment where various pieces of information are distributed in large volumes, recommendation systems are in the spotlight capable of figuring out users' needs fast and helping them with their decisions. The current recommendation systems, however, have a couple of problems including that user preference may not be reflected on the systems right away according to their changing tastes or interests and that items with no relations to users' preference may be recommended, being induced by advertising. In an effort to solve these problems, this study set out to propose a Fuzzy-AHP-based movie recommendation system by applying the BRNN(Bidirectional Recurrent Neural Network) language model. Applied to this system was Fuzzy-AHP to reflect users' tastes or interests in clear and objective ways. In addition, the BRNN language model was adopted to analyze movie-related data collected in real time and predict movies preferred by users. The system was assessed for its performance with grid searches to examine the fitness of the learning model for the entire size of word sets. The results show that the learning model of the system recorded a mean cross-validation index of 97.9% according to the entire size of word sets, thus proving its fitness. The model recorded a RMSE of 0.66 and 0.805 against the movie ratings on Naver and LSTM model language model, respectively, demonstrating the system's superior performance in predicting movie ratings.

Unlike conventional BTO(Build-Transfer-Operate) projects, this BTL project aims at fixing the financial deficiencies of the government and expanding infrastructure through private capital. It allows the government to attract private capital for the construction of public facilities such as schools and social welfare agencies for whom private users don't need to pay, thereby bolstering national finance. BTL projects are causing a variety problems in progress. Therefore, we are required a practical approach to can improving a variety problems. In this study, we were derive the problem areas as follow. First, research data on the problem of domestic BTL projects, Second, high-performing foreign data analysis than domestic. And, we were analyzed to systematic management method for problem areas by using affinity techniques, matrix comparison analysis, AHP technique. Results of this study are expected provide management standards through real problem areas and the analyzing of relatively importance.

Purpose: This paper is for the improvement of the fire gate performance that occurs between the construction company and the residents. A survey was conducted on experts in the construction to prepare the causes and measures for the suit. Method: The application of the Analytic Hierarchy Process(AHP) resulted in the following conclusions. Results: TIn the 2nd tier, 28percent of the "strengthening standards for installation of fire prevention zones" included in the "institutional strengthening of stnadards" of the 1st tier had higher importance. In the 3rd tier, "strengthening the installation standards by floor area" and "strengthening the standard of fire-resistant structures" showed high importance. Conclusion: The results suggest that detailed legal criteria for detailed installation criteria with varying site conditions are needed.

The lack of water resources is becoming a serious issue throughout the world. The water shortage in Korea is expected to increase. Groundwater can be a solution to this matter in some places. Especially, bank filtrations are known to be advantageous over conventional reserviors, even if they have some drawbacks such as their limited location for development and small sizes. The AHP(Analytic Hierarchy Process) is an analytical tool, supported by simple mathematics, which enables one to explicitly rank tangible and intangible factors against each other for the purpose of resolving conflicts or setting priorities. In order to check the applicability of AHP to the evaluation of bank filtration sites, four candidate locations were chosen. They have suffered from problems like water-supply shortage and delayed dam construction. The analysis results are compared with those of the previous study using a conventional method. It is believed that the developed method can a basis for reasonable decision-making regarding bank filtration development.
