In order to explore the job crafting experience of millennial safety workers, this study conducted a qualitative case research with five safety workers of S Energy from March 26 to September 27, 2021 . As a result of the analysis, task crafting showed 'matching one's strong suit with a given task', 'expanding work knowledge using social network service (SNS)', and 'making changes in job performance methods for preemptive safety management activities'. Also, Cognitive crafting showed 'recognition of social vocation as a safety job', 'recognition of a role to grow as a safety management expert', and 'cognitive changes from means of organizational adaptation to enjoyment and energy of life'. At the same time, in relation crafting, 'establishment of amicable relationships through SNS in non-face-to-face and rapid communicating situations', 'safety management made through with mutual cooperations between business people', and 'reborn as a mutual safety net in business relationships' appeared. These can be used as basic data to accumulate the theoretical basis for job crafting research of millennial safety workers and to improve their job satisfaction. A follow-up study was proposed for safety workers with occupations of various kinds.

Existing user research methods are subject to a variety of research conditions such as the amount and variety of data collected and the expertise of the facilitator of a group research session. In this study, we propose a new user research methodology using an 'Issue-Network' system, which is developed based on the theory and methods of social network analysis. The Issue-Network is designed to define problem spaces from the issues raised by users in a group research session in a form of an interactive network graph. The system helps to break out of ordinary perspectives of looking into problem spaces by enabling an alternative and more creative way to connect issues in the network. In this study, we took a case study of generating the Issue-Network on behalf of the problems raised by users in various driving-related situations. We were able to draw three navigation usage scenarios that cover relatively important problem spaces: safety and being ready for the unexpected, smart navigation and notifications, making use of the spare time. In the future, the Issue-Network system is expected to be used as a tool to identify problems and derive solutions in group research sessions involving a large number of users.

Agricultural drought is a natural phenomenon that is not easy to observe and predict and is difficult to quantify. In South Korea, the amount of agricultural water used is large and the types of use are varied, so even if an agricultural drought occurs due to insufficient precipitation, the drought actually felt in the irrigated area is it can be temporally and spatially different. In order to interpret the general drought in the past, drought disasters were evaluated using single indicators such as drought damage area, precipitation shortage status, and drought index, and a comprehensive drought management system is needed through drought diagnosis survey. Therefore, we intend to conduct research on agricultural drought assessment and diagnosis using re-evaluation of agricultural facilities and irrigation water supply network due to changes in various conditions such as climate change, irrigation canal network, and evaluation of water supply capacity of agricultural facilities. In this study, agricultural drought diagnosis was conducted on two agricultural reservoirs located in Sangju, Gyeongsangbuk-do, with structural or non-structural evaluations to increase spatiotemporal water supply and efficiency in terms of water shortages. The results of the agricultural drought diagnosis evaluation can be used to identify irrigated areas and canal network vulnerable to drought and to prioritize drought response.

정보통신기술을 활용한 스마트한 재난관리체계는 가장 빈번하게 발생하는 자연재난과 교통사고 범죄 같은 사회적 재난에 충분히 대비할 수 있고 피해를 줄일 수 있는 한 방안이라고 볼 수 있다. 언제 어디서 어떻게 일어날지 예상할 수 없는 재해에 대비하기 위하여 무엇보다 중요한 것은 적절한 위기의식과 재난 초기의 올바른 선택과 대응일 것이다. 본 논문은 향후 국내 재난안전 부문에서 소셜 네트워크 서비스를 효과적으로 활용할 수 있는 방안을 모색하고자 한다. 이를 위해 해외의 재난안전 분야에서의 성공적 활용 사례를 소개하고 우리나라에 적용 가능한 방안을 도출하고자 한다. 결과적으로 유비무환의 자세로 종합적이고 체계적인 재난관리체계를 도입한다면 피해의 최소화와 신속한 재해복구에 효과적으로 기여할 것이다.

본 연구는 지자체에서 실시하는 'CPTED'와 지자체 안전교육이 '안전생활 만족도'에 미치는 관계를 살펴보며, 무질서의 매개효과를 살펴보는데 그 목적이 있다. 이를 위하여 2017년 수도권지역에 거주자를 모집단으로 하였으며, 임의표집법(Random Sample)을 통하여 300명을 표본으로 추출하였다. 최종분석에는 24부를 제외한 총 276부를 통계처리 하였고, 분석방법으로는 회귀분석과 구조방정식 모형을 통한 경로분석을 실시하였다. 매개효과의 유의미성을 살펴보기 위하여 부트스트랩핑(Bootstrapping)을 실시하였다. 분석결과를 요약하면, 'CPTED'는 '무질서'와 '안전생활 만족도'에 정(+)적인 영향을 미치는 것으로 났으나, '지자체 안전교육'은 '안전생활 만족도'에만 정(+)적인 영향을 미치는 것으로 나타났다. '지역무질서'는 '안전생활만족도'에 부(-)적인 영향을 미치는 것으로 나타났다. 경로분석을 실시한 결과, 동일한 영향을 미치는 것으로 나타났으며, 매개효과를 살펴보기 위하여 부트스트랩핑을 실시한 결과에서도 'CPTED'와 '안전생활 만족도'의 관계에서만 지역무질서가 매개하는 것으로 나타났다. 이와 같은 결과를 종합해본 결과, 지역사회의 안전교육에 변화의 필요성을 시사하는 것이며, 지역사회의 CPTED 지역주민의 안전생활을 위한 안전망으로써 효과적인 수단이라는 선행연구를 지지하는 것으로 볼 수 있다. 국민의 안전을 위한 대책을 마련하는 것은 국가의 가장 중요한 정책 중 하나이다. 지자체 또한 지역주민의 안전한 삶을 보장받을 수 있도록 해야 하나, 사회 안전망으로써의 효과가 선행적으로 입증되어야만 지역사회에 보급하고 운영할 수 있기에 본 연구에서는 지자체 안전망과 무질서 및 안전생활 만족도의 관계를 살펴보았다는 점에서 의의가 있다.

For agricultural water management, it is essential to establish the digital infrastructure data such as agricultural watershed, irrigated area and canal network in rural areas. Approximately 70,000 irrigation facilities in agricultural watershed, including reservoirs, pumping and draining stations, weirs, and tube wells have been installed in South Korea to enable the efficient management of agricultural water. The total length of irrigation and drainage canal network, important components of agricultural water supply, is 184,000 km. Major problem faced by irrigation facilities management is that these facilities are spread over an irrigated area at a low density and are difficult to access. In addition, the management of irrigation facilities suffers from missing or errors of spatial information and acquisition of limited range of data through direct survey. Therefore, it is necessary to establish and redefine accurate identification of irrigated areas and canal network using up-to-date high resolution images. In this study, previous existing data such as RIMS (Rural Infrastructure Management System), smart farm map, and land cover map were used to redefine irrigated area and canal network based on appropriate image data using satellite imagery, aerial imagery, and drone imagery. The results of the building the digital infrastructure in rural areas are expected to be utilized for efficient water allocation and planning, such as identifying areas of water shortage and monitoring spatiotemporal distribution of water supply by irrigated areas and irrigation canal network.

This study established a water supply network based on the operation case of Mandae Reservoir in Yanggu-gun, Gangwon-do, to analyze the efficient distribution and management of agricultural water supplied from the reservoir to irrigation areas using the hydraulic analysis model SWMM. In order to construct a model to analyze the water canal network, network conditions needs to be simplified, and in particular, excessive detail or simplification of the irrigation area can lead to errors in the analysis results. Therefore, the effect of the water canal network model was analyzed by simulating the appropriate simplification process step by step. The results of simplifying the actual block shape of the analysis target area using SWMM showed that there was no significant difference in the results even if 7 lots were simplified to 2. Also, it was found that the construction and analysis of a simplified network model were reliable when the excess quantity was 2% or more compared to the required quantity for each case of analysis of the paddy field.
