  • Recently, the interests in safety and prevention from disaster are increasing. In particular, lifeline networks such as water line and sewerage, electricity, gas, and road would be damaged from a disaster. If the lifeline networks do not work in normal, national public service will not properly function. Researches in social network analysis have been conducted for analyzing the interdependency between individuals since 1970s. These network analysis are utilized to investigate a spread of information and disease. However, it is hard to discover the analyzed cases including characteristics of nodes of networks in the area of transportation and disaster. Therefore, this study conducts network analysis of flooded road with flooding scenarios, investigates safe evacuation routes in flooded road network, and suggests efficient approaches for preventing damages from a flooding.

  • Within last 10 years, internet has become a daily activity, and humankind had to face the Data Deluge, a dramatic increase of digital data (Economist 2012). Due to exponential increase in amount of digital data, large scale data has become a big issue and hence the term 'big data' appeared. There is no official agreement in quantitative and detailed definition of the 'big data', but the meaning is expanding to its value and efficacy. Big data not only has the standardized personal information (internal) like customer information, but also has complex data of external, atypical, social, and real time data. Big data's technology has the concept that covers wide range technology, including 'data achievement, save/manage, analysis, and application'. To define the connected technology of 'big data', there are Big Table, Cassandra, Hadoop, MapReduce, Hbase, and NoSQL, and for the sub-techniques, Text Mining, Opinion Mining, Social Network Analysis, Cluster Analysis are gaining attention. The three features that 'bid data' needs to have is about creating large amounts of individual elements (high-resolution) to variety of high-frequency data. Big data has three defining features of volume, variety, and velocity, which is called the '3V'. There is increase in complexity as the 4th feature, and as all 4features are satisfied, it becomes more suitable to a 'big data'. In this study, we have looked at various reasons why companies need to impose 'big data', ways of application, and advanced cases of domestic and foreign applications. To correspond effectively to 'big data' revolution, paradigm shift in areas of data production, distribution, and consumption is needed, and insight of unfolding and preparing future business by considering the unpredictable market of technology, industry environment, and flow of social demand is desperately needed.

  • As a result of increasing power demand and concern about power supply shortage in the world, various energy sources without depletion of fossil fuel are installed to electrical network. Above all, nuclear energy can be considered as the most economical energy source to generate electricity. But recently, due to problem of safety which has emerged as a key social issue, additional construction of nuclear power plants is difficult. In order to replace nuclear power, researches on the emergency generator have been actively conducting. This study conducted a survey of public institutions about specification of backup generator system and current states to secure available capacity.

  • 최근 스마트폰 시장의 인기와 더불어 모바일 위치기반 SNS가 폭발적으로 성장하고 있다. SNS는 모든 사용자들이 지인과 협력하고 정보를 공유하는 것을 목적으로 하고 있지만, 아직까지 장애인들이 스마트폰과 같은 모바일 SNS를 접하기가 쉽지 않다. 또한 웹을 사용하는데 어려움을 가지고 있는 장애인들이 스마트폰과 같은 기기를 사용하기에 적절한 인터페이스를 제공하고 있는 지에 대한 접근성에 대해 연구할 필요도 있다. 본 논문에서는 상황 인식 기술과 SNS의 기능을 명세하고 분석한 후, 다양한 정보 즉, 시간, 장소 및 활동 상태 등을 포함하는 데이타 수집과 상황정보 분석을 통한 연구를 수행한다. 이를 통하여 장애학생이 편하게 학교생활을 영위하도록 장애유형별 상황인지에 맞는 각종 학사 및 안전서비스를 제공받을 수 있는 모바일 위치기반 SNS 연동 서비스에 대하여 연구한다.

  • The popularity of Social Network Service (SNS) providing web sites has increased continuously by using a variety of mobile devices. The study results show that security of SNS, efficiency of SNS, safety, empathy of SNS quality, easy of use of SNS, assurance of SNS, service variety of SNS are having positive impact to some degree on the user satisfaction. Further, the user satisfaction of SNS users have a positive impact on the continuance usage intention of SNS users. This results show that various SNS qualities are necessary to actively explore and obtain further information that users intend to find, while they are insufficient in function to provide the information other users require or exchange information with other users through the SNS.

  • The purpose of this study is to identify the level of safety perception, ethical awareness, and safety activities of nursing students for patients, and to identify the correlation and impact between them. The research design is a descriptive survey study, and the subject of the study were 197 nursing college students in G City. Safety perception, ethical awareness, and safety activity tools were used for, and the data collection period was from October 17 to 28 in 2022. T-test, one-way ANOVA, Pearson's correlation coefficient, Regression analysis were used to analyze data. The result of the study indicated that the average level of safety perception of nursing students was 3.72 points, the average ethical awareness of patients, professional work, and cooperators perceived by nursing students was 3.04 points, and the safety activities of nursing students were 4.20 points. In the case of safety awareness and ethics awareness, r=.327, a significant positive correlation, in the case of safety awareness and safety activities, r=.399, significant positive correlation, ethics awareness and safety activities as r=.296. And so on these results showed that high safety perception increases safety activities, and high ethical awareness increases safety activities. Therefore, we need practical and step-by-step convergence education to equip nursing students with patient safety nursing capabilities. To this end, a safer environment will be created if the social support network for the systematic application of safety education is well formed.

  • 본 연구는 지역사회 사회안전망구축과 지역사회결속 및 지방자치단체 신뢰의 관계를 규명하는데 있다. 이 연구는 2014년 8월 15일부터 8월 30일까지 약 15일간 광주지역사회 일반시민들을 모집단으로 선정한 다음 집락무선표집법을 이용하여 총 450부를 배부하여 438명을 표집하였다. 최종분석에 사용된 사례 수는 412명이다. 수집된 자료는 SPSSWIN 18.0을 이용하여 요인분석, 신뢰도분석, 다중회귀분석, 경로분석 등의 방법을 활용하였다. 결론은 다음과 같다. 첫째, 사회안전망구축은 지역사회결속에 영향을 미친다. 즉, 범죄예방설계, 지방자치단체안전교육, 경찰치안서비스가 활성화 될수록 시민들의 지역사회제도에 대한 관심은 높다. 거리CCTV시설, 범죄예방설계, 지방자치단체안전교육이 활성화 될수록 안정감은 높다. 둘째, 사회안전망구축은 지방자치단체 신뢰에 영향을 미친다. 즉, 지역자율방범활동, 범죄예방설계, 지방자치단체안전교육, 경찰치안서비스가 활성화 될수록 정책신뢰, 서비스관리신뢰, 업무성과신뢰는 증가한다. 셋째, 지역사회결속은 지방자치단체 신뢰에 영향을 미친다. 즉, 지역사회제도가 잘 이루어질수록 정책신뢰는 높다. 또한 지역사회제도, 안정감이 잘 이루어질수록 업무성과 신뢰는 높다. 넷째, 사회안전망구축은 지역사회결속과 지방자치단체 신뢰에 직 간접적으로 영향을 미친다. 즉, 사회안전망은 지방자치단체 신뢰에 직접적으로 영향을 미치지만, 매개변수 지역사회결속을 통해서 더욱 높은 영향을 미치는 것으로 나타났다.

  • There has been need for safety monitoring systems for the social infrastructures. These infrastructures are subject to degradation over time, reduced functionality, and loss of functionality as a result of factors such as a wide variety of installation environments, natural disasters, and nearby work. Therefore, it is necessary to perform appropriate inspections, repairs, and renovations to ensure safe and efficient maintenance and operation. This paper introduces the example of the development of the safety monitoring system for operating railway tunnel. Tunnel profile measuring system using laser beam, crack gauges, accelerometer and a pluviometer were implemented to monitor the safety of a deteriorated tunnel. The measured data were transferred through wireless network and analyzed in real time. The safety criteria for tunnel stabilities and train operations are also discussed.
