유도진 과장은 정밀기계공업의 강자 중 하나인 S&T중공업의 안전보건 관리자다. 어느 한 가지도 결코 쉬운 업무가 아니지만, 유 과장은 안전과보건, 환경 등 이 세 가지 업무를 빈 틈 없이 이끌어나가고 있다. 어떻게 이것이 가능할까? 바로 '흔들리지 않는 굳은 신념'과 '꺾이지 않는 열정'이 있기 때문이다. 유 과장은 안전 관련 학과를 전공하지도 않았고, 처음부터 안전관리자로 사회에 발을 들이지도 않았다. 단지 사랑하는 동료를 지켜주고 싶은 마음에 스스로 안전을 공부했고, 사랑하는 동료가 건강하게 직장생활을 할 수 있도록 해주고 싶어 보건과 환경을 공부했다. 그렇게 20여 년이 흘렀고, 이제 그는 동료는 물론 지역 안전보건인 모두가 인정하는 베테랑 안전보건 관리자가 됐다.

In recent years, the substantial increase in the population's average age leads to an exceeded number of older persons comparing with the number of any other age group. As a result, both industry and academia are focused on the development of several solutions aimed to guarantee a healthy and safe lifestyle to the elderly. Ambient Assisted Living (AAL) approach is the way to guarantee better life conditions for the aged and for monitoring their health conditions by the development of innovative technologies and services. AAL technologies can also provide more safety for the elderly, offering emergency response mechanisms, fall detection solutions, and video surveillance systems. Unfortunately, due to the sensitive nature of AAL data, AAL systems should satisfy security requirements such as integrity, confidentiality, availability, anonymity, and others. In this paper, we propose an adaptive authentication protocol for the AAL systems. The proposed authentication protocol not only supports several important security requirements needed by the AAL systems, but can also withstand various types of attacks. In addition, the security analysis results show that the proposed authentication protocol is more efficient and secure than the existing authentication protocols.

현대 사회 생활의 변화는 맞벌이 가정의 증가, 인스턴트 식품의 증가, 과잉섭취 등을 가져왔고 이는 청소년의 비만을 빠르게 증가시켜 성인병의 가장 중요한 원인인 비만 치료에 대한 요구가 높아지고 있으며, 학생들은 하루 생활의 대부분을 학교에서 보내고 있는 만큼 비만학생에게는 지속적인 학교보건교육 및 지도를 통한 치료가 필요하며, 이를 위한 윕 기반 시스템을 제안한다. 그리고 학교 생활에서 일반학생들보다 더 많은 주의를 필요로 하는 요양호(건강이상) 학생들에 관한 정보를 가정, 특정수업시간 등에서 변화가 생길 때마다 실시간으로 입력하고 이 정보를 공유하여 요양호 학생들의 건강하고 안전한 학교생활을 위하여 본 시스템을 제안한다.

This study improves the design of electric pot and cup that can safely pour and drink hot beverages among daily necessities for the blind and the elderly. It looks at the electric pot and cup that people with visual impairments usually use through their use perspective and studies and improves the safety problems that arise when using them based on the principle of universal design. Through this prior study, we study designs that can be used and shared by all disabled and socially disadvantaged people together and improve the design of household goods to expand the scope of use of general products and create new social values. In addition, through this design improvement process, everyone pursues an equal and virtuous life together, forms a well-off inclusive society, and takes advantage of the current position of the disabled and value of life once again.

This study aims to provide primary data for R&D on rollator-walking frame through researching the usability test of the rollator-walking frame and the effect of rollator-walking frames on the lives of senior citizens. This study surveyed 60 senior citizens living in Sungnam City in South Korea. As the result of the usability test, we can find users' dissatisfaction with the folding, weight, shape of backrest and material of chair. The survey shows that the frequency of outdoor activity is mostly increased by the convenience of product. However, the inconvenience while using facilities, such as elevators or public transportations, gave a significant impact on the decrease in going out experiences. Therefore, for better outside lifestyle of senior citizens, it is important to improve the function of the product, however, we need to make improvement of urban infrastructure.

At the current camera-based technology level, sensor-based basic life pattern recognition technology has to suffer inconvenience to obtain accurate data, and commercial band products are difficult to collect accurate data, and cannot take into account the motive, cause, and psychological effect of behavior. the current situation. In this paper, radar technology for life pattern recognition is a technology that measures the distance, speed, and angle with an object by transmitting a waveform designed to detect nearby people or objects in daily life and processing the reflected received signal. It was designed to supplement issues such as privacy protection in the existing image-based service by applying it. For the implementation of the proposed system, based on TI IWR1642 chip, RF chipset control for 60GHz band millimeter wave FMCW transmission/reception, module development for distance/speed/angle detection, and technology including signal processing software were implemented. It is expected that analysis of individual life patterns will be possible by calculating self-management and behavior sequences by extracting personalized life patterns through quantitative analysis of life patterns as meta-analysis of living information in security and safe guards application.

The main purpose of this study is to examine the relationship between the safety awareness and safety practice behavior of the college students. We carried out a questionnaire survey that was targeted at 294 college students from November 1st to November 20th, 2014. Data collected were analyzed with SPSS 18.0 statistical program. Analysis methods were t-test, one way ANOVA, Scheffe test, Pearsons correlation coefficient, and Stepwise multiple regression analysis. The findings are as follows. Safety awareness point was an average of 177.5 points which was higher levels. Area showing the highest safety awareness was safety from fire. Safety practice behavior was an intermediate level of an average 63.3 points. Also, there was a positive correlation between safety awareness and safety practice behavior(r=.595. P<.01). The results of this study implies that we need the safety training program for the safety awareness of college students.
