Global food prices have skyrocketed due to international uncertainties such as COVID-19 and the Russian-Ukrainian War. In this context, the importance of rural areas as a source of food production is also rapidly increasing. However, the issue of regional extinction is emerging as Korea faces the world's lowest fertility rate and fastest aging population. Also, rural areas are losing their population more rapidly than large cities. Therefore, this study aims to analyze the factors that can encourage the influx of fishermen to prevent the disappearance of these fishing villages. As a result of the analysis, in order to prevent the disappearance of fishing villages, among the infrastructure, natural environment, and residential environment variables, the ratio of aged housing related to quality of life, culture and amenities coefficients were found to have a greater impact than other variables. Based on these results, it is judged that it is necessary to establish a sufficient level of infrastructure in fishing villages and to prioritize policies for improving the residential environment.

차세대의 통신 환경은 디지털들이 통합되는 컨버전스 시대를 맞이하여 인터넷 통신의 환경과 유선망과 무선망과 컴퓨터네트워크 망들이 통합되는 유비쿼터스 환경으로 접어들고 있다. 따라서 현재의 대다수의 교육기관에서는 Intranet을 통한 정보시스템을 구축하고 있으나 유비쿼터스 환경에서 모든 정보는 Extranet을 통해 유무선망을 통해 외부에서 접근 가능한 시스템으로 관리되고 있다. 따라서, 본 논문에서는 유비궈터스 환경 하에서의 학사정보시스템의 설계 방법에 대하여 제안한다.

With an increase in the penetration of offshore wind farm, the need of an accurate economic evaluation of offshore wind farm has become crucial. This paper presents an economic evaluation method of offshore wind farm in Korea reflecting the cost of offshore wind farm infrastructure (offshore substation, submarine cable and foundation) in its cost model. Each cost of offshore substation, submarine cable, and foundation is represented as a function of installed capacity, distance to shore, and water level, respectively. We have applied the method to the case study of offshore in Jeju Island and analyzed the economics under various conditions. The results show that the distance to shore is of importance in economics of offshore wind farm.

During the last thirty years many structural control concepts have been proposed for the reduction of the structural response caused by earthquake excitations. Their research and implementation in practice have shown that seismic control of structures has a lot of potential but also many limitations. In this paper the importance of two practical issues, time delay and saturation effect, on the performance of controlled structures, is discussed. Their influence, both separately and in interaction, on the response of structures controlled by a modified pole placement algorithm is investigated. Characteristic buildings controlled by this algorithm and subjected to dynamic loads, such as harmonic signals and actual seismic events, are analyzed for a range of levels of time delay and saturation capacity of the control devices. The response reduction surfaces for the combined influence of time delay and force saturation of the controlled buildings are obtained. Conclusions regarding the choice of the control system and the desired properties of the control devices are drawn.

The number of researches on the mechanical properties of cemented sand and gravel (CSG) materials and the application of the CSG Dam has been increased. In order to explain the technical scheme of strength prediction model about the artificial neural network, we obtained the sample data by orthogonal test using the PVA (Polyvinyl alcohol) fiber, different amount of cementing materials and age, and established the efficient evaluation and prediction system. Combined with the analysis about the importance of influence factors, the prediction accuracy was above 95%. This provides the scientific theory for the further application of CSG, and will also be the foundation to apply the artificial neural network theory further in water conservancy project for the future.

The importance of Electronic Commerce and internet has been rapidly increasing. For the global information society in the $21^{st}$ century, government aims for the successful execution of the project for the construction of KII(Korea Information Infrastructure). However, the research on applications of KII is not enough to relate with Electronic Commerce and its impact. In this paper, we present a brief introduction to KII and its characteristics. Through the detailed analysis of application factors on KII, the relationship and inter-necessity between KII and Electronic Commerce are investigated. Also, This, work studies the aspects of law, security, and Informatization- mind for the guided directions of activating Electronic Commece on KII. Finally, the implementation strategy for Electronic Commerce is suggested.

Present PII(Private Infrastructure Investment) in Korea has increased up to 11% compared to the year 2003 and is expected to increase in the future. In spite of its rapid increase, we don't have any definite standard or system which distinctly presents the rate of return for domestic PII yet, and practical and scientific research is not sufficient compared to its necessity and importance. Hence, in this study we suggests methods to estimate the rate of return of PII to promote SOC PII to last successfully and present the proper level of rate of return of PII which is appropriate for domestic situations through diverse analysis. Therefore, to present reasonable rate of return, we have used 5 methods: previous research analysis, case study, financial index analysis, analysis of investor's rate of return, and analysis of rate of return in a real estate market. After comparing and analyzing these methods, at the end, we have presented the appropriate level of rate of return of PII, which can be applied in the domestic market.

Owning to rapid infrastructure development, Asia is experiencing dramatic economic growth. There are not a few cases in which, however, economic growth is achieved by increasing the external diseconomy. Pursuit of sustainable development is one of the most important issues for mankind. Under the post-industrial capitalism society, however, there seems a big risk of increase in the external diseconomy worldwide. The objectives of this manuscript are to discuss importance of risk management of construction practice in present and future. Regarding the latter, a particular attempt is made to discuss how project risk communication should be done to reduce the external diseconomy. Presently, one of the important issues in implementation of infrastructure projects is practice of risk management to properly manage time, cost, quality, and safety: mainly maximization of internal economy. Multi-party risk and uncertainty management process (MRUMP) is one of tolls to assist it. The idea on MRUMP can be used to reduce the external diseconomy through identifying, sharing, and tuning people's rhythms.

Due to the deterioration of infrastructure, the importance of maintenance is continuously increasing. Therefore, an integrated maintenance method for various facilities is required. In this study, a maintenance priority determination method for integrated maintenance of roads and pipe network facilities was developed. It is possible to analyze attribute information by using GIS data of roads and pipe networks, and shape information can be used. This information is derived as quantitative figures for determining maintenance priorities. In the future, it is expected that facility maintenance can be further advanced in connection with maintenance method and quantity information for each facility.

본 연구는 국내 민간 현대무용단의 활성화를 위한 방안으로 전문가들의 의견을 듣고 중요도와 시급성을 측정하였다. 먼저 신산업육성 이론을 적용하여 전문가 그룹 5명에게 개방형 FGI(Focus Group Interview)를 실시하였고 중요하게 언급되거나 반복된 내용을 통해 총 24가지의 2차 질문지를 개발하였다. 이를 각 무용단 대표 및 기획자, 대학교수 등 20명에게 배포하였으며 전문가 중요도와 시급성을 측정하였다. 연구결과, 대항목은 중요도와 시급성 모두 자금지원이 1순위로 나타났고, 소항목 중요도, 시급성 비교분석은 인프라구축에서 차이를 나타냈는데, 중요도 1순위는 '무용프로그램의 홍보채널 확대", 시급성 1순위는 "무용단 전용공간 확보"로 나타나 차이를 보였다. 이와 같은 결과를 분석한 시사점은 다음과 같다. 자금지원 측면에서는 "무용단 운영을 위한 세분화된 자금지원" 등 공연 및 교육관련 작품개발 측면에서는 "기획 및 연출 등 전문인력 채용" 인력양성 측면에서는 "복합장르를 소화할 수 있는 안무자 양성" 인프라구축 측면에서는 "무용단 전용공간 마련" 컨설팅 지원 측면에서는 "기획 및 연출 등 전문인력 채용"으로 나타났다.
