The operation of the theater's seasonal program is an important service for the stability of theater management and audience development. However, the domestic theater season system has been around for 20 years, but still has not been established in practice compared to overseas theaters, and academic research is also lacking. Therefore, in this study, the government wanted to draw out elements of 'season system' program services and additional services provided by domestic and foreign theaters, and to calculate the importance of each attribute to suggest a plan to operate a seasonal service suitable for the actual conditions in Korea. Thus, through the analysis of seven theater seasonal programs, a study model consisting of two higher, seven median and 23 lower factors was derived. Based on this survey, 14 theater experts were asked to compare the priorities of each factor. Studies have shown that the composition of packages and works in program services is important, and that monetary factors are important in additional services. In other words, an important element in the seasonal system is judged to be the need to upgrade program services and selectively operate a small number of additional services with large audience needs to attract audiences.

Photovoltaic system is the core one among the new and renewable energy of the low Carbon and green growth. Recently, the necessity developing PV is emerging since its of less green hose gas emissions. However, a survey or research on the PV system has been hardly performed. It's not easy to find a appropriate location in consideration of environment. These circumstances encourages a systematic approach for the PV system development. The purpose of this study is to propose a methodology of the location analysis for developing PV system. With this, constraint and location criteria with weights of Analytic Hierarchy Process are established and quantification method of each factor is presented. The location analysis of PV system using the GIS were generalized and the results of analysis for redundant topographic features were presented as 3 criteria of the suitability rank.

Many businesses have adopted the standard security management structure such as ISO27001 and K-ISMS for strengthening business's security management structure to protect their core information assets and have acquired partial output from such effort. However, many risk factors such as recent advances in Information Technology and evolution of intrusion methods have increased exponentially requiring the businesses to response even more quickly with better accuracy. For such purpose, a study of 'Real Time Security Management Structure for Business' based on security management process optimization, defining a set of security index for managing core security area and calculation of risk indices for precognition of intrusion risk area has been made. Also, a survey on opinions of an expert panel has been conducted. The effectiveness of studied structure was analyzed using AHP method as well. Using this study, security personnels of a company can improve efficiency of the preemptive responsive and quicker measure from the current security management structure.

개발로 인한 환경변화는 관련 분석모형을 통해 직접적으로 예측하기 하는 것이 가장 바람직하지만 데이터 취득의 어려움, 분석 방법론의 부재 등의 이유로 정량적 평가가 어려운 현실이다. 그렇기 때문에 수자원사업을 계획시 대부분 환경적인 영향을 매우 정성적인 형태로 평가하거나 수질과 같은 대표적인 항목에 대해서만 예측하는 수준이다. 기존의 연구 또한, 유역 또는 행정구역의 현재의 현 상황을 평가하기 위한 것이 주이며, 수자원사업과 관련성이 적은 항목도 일부 포함되어 있기 때문에 수자원사업의 특수성을 반영하기에 한계가 있다. 현 상황의 이러한 문제점을 인식하여 본 연구는 오늘날 대표적 의사결정 기법이라 할 수 있는 계층화분석과정(AHP)과 다속성효용이론(MAUT)을 활용하여 향후 수자원사업과 관련된 다기준의 사결정 과정에서의 환경성 평가방안을 제시하였다. 환경성 평가기준은 수질, 경관, 생태계 이렇게 세 가지 항목으로 구성하였고, 각 평가기준에 대한 수준을 직접적으로 대변 가능한 정량화 방안을 제시하였다. 그리고 앞서 정량화된 값을 표준화하기 위하여 MAUT 기법으로부터 평가기준별 효용함수를 도출하였다. 한편, 사업을 시행함에 따라 예상되는 환경성변화는 사업전 환경성과 사업 후 환경성을 비교하도록 하였고, 이때 해당사업의 특수성을 반영하고자 별도의 설문과정을 통해 평가기준별 가중치를 결정하였다. 본 연구는 환경성 검토시 생태학적, 물리적 분석에 기반을 둔 정량적 예측의 어려움을 보완하기 위해 정성적 예측을 추가적으로 제시하였고, 사업의 특수성과 평가항목이 갖는 일반성을 명확히 구분하여 의사결정 과정에서 주관적인 요소를 최소화하였다. 또한, 평가항목별 사업전후의 환경성을 비교, 검토함으로써 실제 사업추진 과정에서 개발로 인한 부정적 영향의 사전예방에 도움을 줄 수 있을 것으로 판단된다.

This paper aims to develop an appropriate methodology for establishing an investment strategy for 'demonstration of artificial rainfall technology using UAV' and that include establishment of a technology classification, set of indicators for technology evaluation, suggestion of final key technology as a whole study area. It is designed to complement the latest research trend analysis results and expert committee opinions using quantitative analysis. The key indicators for technology evaluation consisted of three major items (activity, technology, marketability) and 10 detailed indicators. The AHP questionnaire was conducted to analyze the importance of indicators. As a result, it was analyzed that the attribute of the technology itself is most important, and the order of closeness to the implementation of the core function (centrality), feasibility (feasibility). Among the 16 technology groups, top investment priority groups were analyzed as ground seeding, artificial rainfall verification, spreading and diffusion of seeding material, artificial rainfall numerical modeling, and UAV sensor technology.

Newly, the fourth industrial revolution is a way of describing the blurring of boundaries between the physical, digital, and biological worlds. It's a fusion of advances in AI (artificial intelligence), robotics, the IoT (Internet of Things), 3d printing, genetic engineering, quantum computing, and other technologies. At the world economic forum in Davos, switzerland, in january 2016, chairman professor klaus schwab proposed the fourth industrial revolution for the first time. In order to apply the AHP (analytic hierarchy process) analysis method, the first stage factors were designed as Natural, Water, Earth and Atom energy. In addition, the second stage factors were organized into 9 detailed energies presented in the conceptual model. Thus, we present the theoretical and practical implications of these results.

As the worldwide trade of agricultural products became liberalized with the establishment of WTO and FTA, relatively cheaper agricultural products have influenced the Korean domestic market substantially. Fortunately, foreign countries have soften their restrictions on Korean agricultural exports, providing Korean farmers with more opportunities to advance into the world market. This study aims to propose a multiple-criteria decision-making model for selecting an optimal tomato export farm, as the part of an effort to vitalize exports of domestic agricultural products amid the competitive agricultural market worldwide. For this purpose, we are suggesting a 2-step decision-making model which consists of a simple hierarchy decision model that preliminary selects tomato export farms and a detailed hierarchy decision model that chooses the final and optimal tomato export farm. We applied the analytic hierarchy process (AHP) to determine the relative importance of the used evaluation factors and to choose the tomato export farms with most potential. Eventually, the systematic and efficient decision-making model proposed in this paper can be applied to determine the optimal export farms for crops other than tomato, and thus it can encourage the competitiveness of Korean agricultural exports.

The spatial structure analysis using the existing space syntax has a weakness only to apply the road factor. Hence, it is necessary to perform a new spatial structure analysis considering the regional characteristics factor as well as the road factor. The purpose of this study is to propose a modified spatial structure analysis which adopts road and regional characteristics factors using the existing space syntax and GIS and then to apply it to the spatial structure analysis of the urbanized areas in Hapdeok town. For the new analysis, the experts' survey has been conducted to derive the spatial structure factors of the area and their relative weights. Specifically, it drew the road factor as well as the regional characteristics factors such as road, district, land value, and building density. This study shows that the existing spatial structure analysis considering only the road factor does not reflect the actual spatial structure but the modified spatial structure analysis considering the road factor and the regional characteristics factors more accurately analyzes the spatial structure of Hapdeok town. Hapdeok is not an area where road networks were developed along main development axis and its centrality was changed, but an area where road networks were developed by effectiveness and equity and its centrality was changed by downtown decline. The towns like Hapdeok is more suitable for applying the modified spatial structure analysis method considering the regional characteristics factors. Further research is required for selecting characteristics factors and appropriate parameters in the modified spatial structure analysis. Further case studies await in other cities for conducting its verification.
