인간이 서서 걸으면서 나타나는 필연적인 증상의 하나인 요통은 전체 인구의 80%가 일생에 한 번 이상 경험하며, 20%정도는 항상 허리통증에 시달린다는 보고가 있다. 본 논문에서는 앉은 자세로 인한 요통에 대해서 연구하였다. 앉은 자세 변화에 따라 발생하는 작업자의 근육 근전도를 조사하고 분석하여, 인간공학적으로 적합한 앉은 자세 평가에 표면 전도의 유용성을 알아보았다. 개인에 따라 차이가 있지만 허리에 주는 부담은 앉아 있는 것이 누워 있을 때에 비해 7배, 서 있을 때보다 3배 정도로 크다. 머리를 숙이고 웅크리고 앉아 있거나 등을 구부정하게 앉아 있는 것은 체중이 골고루 분산되지 않아 허리에 주는 부담이 더 크다. 따라서 나쁜 자세로 인해 생기는 요통은 무엇보다 적절한 운동을 통해 복부와 허리의 근육을 강화시켜주는 것과 함께 자세를 바르게 갖도록 해야 한다. 등근육 근전도 신호를 이용하여 자신의 자세정보를 알 수 있도록 하여 앉은 자세를 관찰하고 자세가 바르지 못할 경우 스스로 바른 자세를 유지할 수 있도록 유도함으로써 나쁜 자세로 인한 요통 예방에 도움을 주고자 한다.

This study analyzed working postures using the Ovako Working Posture Analysis System (OWAS) to improve work clothes for construction workers. A video taken at a construction work site was stopped at regular intervals and the postures of relevant body parts proposed by OWAS was recorded. Additionally, based on analysis of the working postures code, the level of work action for each postures was classified from stage I to IV. General workers frequently straightened or bent forward at the waist, and used their legs to stand, bend, or walk. Wood workers moved extensively from the waist, keeping their legs relatively straight and their arms held below their shoulders, repeatedly tapping with a hammer weighing less than 10.0kg. Rebar bending workers mainly bent forward at the waist, with both legs bent or standing with one leg bent. Rebar transport and fixing workers walked with the waist straight, and occasionally one or both hands held above the shoulders. Their work also involved holding a hook, which weigh less than 10.0kg, in their hands, and the difficult task of lifting and placing long rebars, which weigh from 10.0 to 20.0kg or more. Concrete pouring workers bent or twisted their back to the side. Therefore, this study suggests that design goals should be different when developing workwear for each type of worker.

새로운 한해를 시작하면서 산업현장에서는 새로운 가족을 맞이하고, 각종 교육이 한창이다. 그 중 안전교육은 사회에 첫발을 내딛는 신규근로자에서 매우 중요하다. 처음부터 안전문화를 어떻게 접하느냐에 따라 안전마인드가 형성되기 때문이다. 따라서 이번달에는 신규근로자가 가져야 할 자세에 대해 언급하고자 한다.

ICT 기술의 발달에 따라, 현대인들이 컴퓨터 앞에서 작업하는 시간은 증가했으며 장시간 의자에 앉아 한 자세 및 부적절한 자세와 생활 습관으로 인한 척추 측만증 및 허리 디스크 발병률은 점점 증가하고 있다. 척추는 몸을 지탱하는 기둥으로써 사람의 몸의 중추적인 역할을 하는데 척추가 여러 원인으로 꼬이고 굽어져 'S'형으로 흰 상태를 척추 측만증이라고 한다. 유비쿼터스 컴퓨팅 기술의 발달로 언제 어디서나 자신의 건강상태를 모니터링 할 수 있는 U-Health 시스템이 주목받고 있기 때문에 따라서 본 논문에서 일상 생활에서도 자신의 자세를 측정 및 교정이 가능하며 센서로부터 측정한 값은 사람의 체형마다 다르다는 단점을 보완하고 환자-의사가 통신 할 수 있는 IoT를 결합한 아두이노 기반의 척추 측만증 예방을 위한 자세 교정기 및 U-Health 시스템을 개발하였다.

최근 국내의 산업재해율 증가에 있어 특이한 사항은 근골격계질환, 뇌심혈관질환 등 작업 관련성질환에 의한 증가 현상이다. 특히 단순반복작업, 중량물 취급작업, 부적절한 작업자세 등에 의하여 신체에 과도한 부담을 주었을 때 나타나는 요통, 경견완장해 등 근골격계질환은 매년 급증하고 있으며(Table 1 참조) 향후에도 지속적인 증가가 예상된다.(중략)

자재나 반제품의 이동시에 자주 사용되는 대차는, 동력이 필요없으면서도 협소하고 복잡한 통로를 신속하고 손쉽게 왕래할 수 있다는 장점 때문에 작업현장에서 빈번히 행해지고 있지만, 여러 공급업체에서 납품된 형태 그대로 이용되고 있어 그 규격이나 형태도 제 각각이다. 작업자들의 신체조건이 고려되지 않은 대차는 작업자들로 하여감 무리한 작업자세나 동작을 유발시키거나, 심한 경우 요통재해를 발생시킬 수 도 있다. 또한 시야가 확보되지 못할 정도로 큰 대차와 부적합한 통로로 인하여 충돌사고의 위험성도 있다. (중략)

Working Posture is an important factor directly connected with quality and productivity of the construction project. In particular, High-rise building construction is required to manage the working posture due to the repetitive task and unfavorable working condition such as high place work, limited space. However existing construction planning of high-rise building construction has a negative effect on the labor's productivity because it is not insufficiently considered for working posture. Therefore the purpose of this study is to suggest a work that needs improvement by analyzing labor's working posture quantitatively using OWAS method. These results would provide the basic information to improve the productivity of the construction project by supporting the construction plan considering the working posture in high-rise building.

The purpose of this study was to investigate the current status of work-related upper extremity musculoskeletal pain in baristas and to identify the elements that are related to pain. The questionnaires were distributed to 100 workers in 63 cafes on Jeonju city in Korea. As a result of investigating work related pain, 65.3% (n=64) answered "yes" to the question that had pain at least once a week, month, or year, or 34.7% (n=34) answered "no". Most of the workers were right-handed, and when they felt pain, they felt 25 to 50% of time per day. Especially, baristas reported that the use of porter filters during work and the tamping operation were the most painful. In conclusion, our study indicated that necessary to introduce and develop a program to prevent cafe worker disease, as well as need to future research to improve work environment and posture according to the characteristics of the cafe works.

With the outbreak of COVID-19 a few years ago, video conferencing and electronic document work have increased, and for this reason, the proportion of computer work among modern people's daily routines is increasing. However, as more and more people work on computers in the wrong posture for a long time, the number of patients with poor eyesight and text neck is increasing. Until recently, many studies have been published to correct posture, but most of them have limitations that users may experience discomfort because they have to correct posture by wearing equipment. A posture correction sensor algorithm is proposed to prevent access to the minimum distance between a computer monitor and a person using an ultrasonic sensor device. At this time, an algorithm for minimizing false alarms among warning alarms that sound at the minimum distance is also proposed. Because the ultrasonic sensor device is used, posture correction can be performed without attaching a device to the body, and the user can relieve discomfort. In addition, experimental results showed that accuracy can be improved by reducing false alarms by removing more than half of the noise generated during distance measurement.

This paper studies natural head position and orofacial pain. For this study. 27 persons with dental service were selected, we examine head & neck pain, factor affecting pain severity, stress, stressful facial symptom with questionarre and interview. We have photograph for natural head position in front of 5cm posture scale pate. Data obtained were statistically processed by the SPSS Windows program and the results of this study were as follows: 1. There were significant difference from plum line to acromion line, from plum line to tragus line, eye- tragus angle, SCM angle. 2. Between group with head and neck pain and group without head and neck pain, the study shows no significant difference on average NHP measurement and NHP amount. 3. Between group with head and neck pain and group without head and neck pain, the study shows no significant difference on SRRS. 4. In this paper we indicate more stressful symptom in group with head and neck pain than group without head and neck pain. 5. There have no difference in head and neck pain level according to hobby.
