건설현장 근로자의 안전과 개인정보 보안이 강화된 블록체인 기반 센서 네트워크의 프레임워크 구축
이희림(Lee, Hee-Rim),송승현(Song, Seung-Hyun),윤혜성(Yoon, Hye-Sung),황성주(Hwang, Sung-Joo) 대한건축학회 2018 대한건축학회 학술발표대회 논문집 Vol.38 No.2
As the diffusion of the Internet of Things(IoT) based on sensors is activated in the construction site, the type and amount of information to be collected is expanded, which may lead to concern about workers" information leakage and privacy invasion. Therefore, the purpose of this study is to investigate the problem of personal information leakage and workers" privacy invasion in sensor networks used for safety management in construction site, and to examine the applicability of block chain technology as a solution to this problem. As a result of the research, personal information of workers collected by sensor technology that can be applied to the construction site is classified into location, movement, and physiological information. The location information has the possibility of invasion of privacy at break time instead of working time, and the movement information can be abused for the purpose of job evaluation through real-time monitoring, physiological information can suggest the possibility of transferring responsibility to workers in case of construction safety accident. Although the client server structure is mainly used in the sensor network architecture that transmits and shares such information, there are vulnerabilities such as load centralization on the server side, data tampering, and deodorization. Therefore, we constructed a framework of sensor network that secures privacy of construction workers and enhances personal information security by utilizing characteristics such as decentralization, security, anonymity, speed, and scalability of the block chain technology. The expected effect of this study can improve the negative perception of the worker "s sensor attachment. Also, an efficient system can reduce costs and shorten information sharing time, and clear accountability after an accident. In addition, it can contribute to the minimization of damage caused by construction accident by providing information with higher reliability to workers quickly.

Bruxism is the masticatory muscle activities involving grinding or clenching the teeth, which is divided into sleep and awake bruxism. Methods for evaluating sleep bruxism include clinical methods to investigate symptoms and signs and the use of supplementary tests such as intra-oral devices, electromyography, and polysomnography. Portable electromyography monitoring the masseter muscle activity is useful for clinical application. Polysomnography is the most accurate method for diagnosing sleep bruxism.

자전거 출퇴근자의 의복 선택에 영향을 미치는 요소 및 요구사항 조사연구
유신정(Yoo, Shin Jung),이명주(Lee, Myung Joo),이희림(Lee, Hee Rim) 한국디자인문화학회 2015 한국디자인문화학회지 Vol.21 No.4
자전거 이용이 저탄소 정책의 성공과 연결되기 위해서는 운동으로서의 수단이 아니라 출퇴근시 자가용 이용을 대체할 수 있어야 한다. 따라서 본 연구에서는 자전거 출퇴근 자들이 느끼는 환경 중 의복적 측면에서의 불편함과 요구, 선호 등을 조사하여 자전거 출퇴근 전용 전문 스마트웨어 개발을 위한 기초적인 자료를 제공하고자 수행되었다. 자전거로 출퇴근 하는 남성 110명을 대상으로 온, 오프라인 설문을 통해 자료가 수집되었으며 자전거 출퇴근에 따른 환경과 의복관련 전반적인 문제점과 선호요인이 조사분석되었다. 연구 결과 가장 영향을 미치는 요소는 눈과 비, 바람과 같은 외부 환경요소였으며 출퇴근 후 샤워문제와 같은 부대시설의 미비도 문제점으로 느끼고 있는 것으로 조사되었다. 자전거 출퇴근 용 의복 선택 시 중요시 하는 요소는 디자인보다 기능성과 가격으로 나타났다. 현재는 자전거 출퇴근시 전문사이클용 자전거 복을 주로 착용하고 있으나 화려하고 지나치게 눈에 띄는 색상이나 무늬, 몸에 밀착되는 소재와 디자인 등에 불만을 가지고 있었고 선호하는 기능으로는 주행 중 땀처리, 외부환경으로부터의 보호, 휴대와 세탁의 용이함 등이 포함되었다. 출근 후 젖은 옷의 처리 문제도 해결 받기 원하는 큰 문제점으로 조사되었으며 스마트 웨어가 개발된다면 가장 기대하는 성능은 가변적인 체온조절 기능, 유해환경으로부터의 보호인 것으로 조사되어, 자동차와 같이 보호되지 않는 환경에서의 출퇴근을 위한 자전거 타기에서 가장 기대하는 성능은 다변하는 날씨로 부터의 보호와 쾌적성(protection and comfort)이라는 것을 알 수 있었다. For the sake of low-carbon policy, bicycle should be used as a transport for commuting. The purpose of this study was to figure out difficulties, demands, and preference of bike commuters in terms of environment and clothing in order to provide fundamental data for developing smart clothing for bike commuters. 110 bike commuters were participated via on/off line survey. Results showed that the most influencing factors for bike commuting were environmental situation, such as rain or snow. Difficulty of taking shower after riding was one of the main problems. Important considering factors when purchasing cycling clothing were function and price rather than design. Most of respondents were wearing cycling wear for bike commuting but dissatisfied with loud color/pattern and skintight design/fabric. Preferred functions were sweat management during riding, protection against dangerous environment, and easy to carry/maintenance. Management of wet clothing after riding was one of the biggest problems, especially in summer. As for the expecting performances of smart clothing for bike commuters, versatile control of body temperature and keepping riders comfortable from various situations during riding. Overall, protection and comfort against adverse environment such as changeable weather and harsh conditions (protection and comfort) were the main demands for the smart clothing for the bike commuters.

사물인터넷 기반 빅데이터 분석을 활용한 스마트 건설안전관리 프레임워크 개발에 관한 연구
홍민영(Hong, Min-Young),박주연(Park, Ju-Yun),이희림(Lee, Hee-Rim),임채은(Im, Chae-Eun),장혜진(Jang, Hye-JinSon),손정욱(Son, Jeong-Wook) 대한건축학회 2017 대한건축학회 학술발표대회 논문집 Vol.37 No.2
The purpose of this study was utilize the Internet of Things and big data analysis, which have become very important recently, in the construction industry. Construction industry showed higher industrial accidents than other industries. Also, a lot of data was collected at the construction site, but it disappeared without being utilized. So, we collected and analyzed various data that was related to construction safety and derived meaningful information. And we have developed smart construction safety management framework using big data analysis based on Internet of Things technology.
