대부분의 작업환경에서는 여러 가지 위험요소로 인한 안전사고가 자주 발생한다. 추락이나 작업환경의 붕괴 등 안전사고 발생시, 작업자가 관리자에게 응급상황을 전해야하지만, 사고로 인해 작업자가 원활하게 몸을 사용하지 못하는 경우에는 응급상황을 전달하는데 문제점이 발생한다. 본 논문에서는 이러한 문제를 해결하기 위해서 블루투스로 스마트폰에 응급상황을 전할 수 있는 웨어러블 단말기와 스마트폰의 WI-FI나 LTE망을 사용하여 작업자의 상황을 실시간으로 모니터링 할 수 있는 안전 시스템을 설계한다.

Objectives: Skin exposure to diisocyanates may be an important risk factor for respiratory sensitization to leading asthma. However little is known about the extent of worker's diisocyanates skin exposure and the effectiveness of personal protective equipments in polyurethane foam manufacturing companies. This study provides data on diisocyanates skin exposure, surface diisiocyantes contamination of foams and the effectiveness of personal protective gloves in five polyurethane foam manufacturing companies. Materials and methods Colorimetric SWYPE pads are used for the determination of diisocyanates on surfaces of workers skin and polyurethanes foams. Results: The forearms, necks and faces of workers in polyurethane foam manufacturing companies were found to be contaminated with diisocyanates. Heavy contamination with uncured diisocyanates at large block foams surfaces were found. Personal gloves of workers for skin protection showed significant penetrations by diisocyanates. Conclusions: We found that all workers in polyurethane foam manufacturing companies could be exposed to diisocyanates by skin exposure. Also further researches which would better quantify skin exposure are needed.

Silicon Valley's legal foundation in recent years has surfaced on the radar of policy planners who model Silicon Valley's ICT industry. Precisely, the prohibition of covenants not to compete is linked to firm to firm knowledge spillovers by way of mobile workers positioned as nodes in a system of innovation. Meanwhile, traditional frameworks support enforcement of covenants not to compete as a way to encourage R&D into the worker and to prevent the worker's tacit knowledge and know-how from fleeing. This article examines the ICT industry in Silicon Valley and Route 128 to argue that California's unique law is a key factor in the success of Silicon Valley firms. Theoretically, we reconcile the ostensible strife between enforcement and prohibition frameworks by presenting an industrial approach. We contend that selective enforcement by industry can maximize the policy tools of discorded planners.

The aim of this study is to develop an ergonomic design of magic saw handle considering user experiences. Background: Frequent use of hand tool can cause musculoskeletal disorders by inadequate wrist posture, excessive strength, repetitiveness, friction and pressure, vibration, etc. A hand tool that is inappropriately designed has higher risk causing musculoskeletal disorders. Complaints for the design of magic saw handle has been raised by many users according to the increasing use of magic saw. Method: Hand tool has to be designed considering worker's characteristics and task condition to prevent worker's musculoskeletal disorders. For this, user experiences for magic saw handle were measured through questionnaire survey and observation. Results: An ergonomic design of magic saw handle considering user experiences was proposed and then its design suitability was evaluated in comparison with the existing handle design using EMG and subjective evaluation. Conclusion: The proposed handle design showed higher satisfaction and lower muscular fatigue. Application: The results of this study can be effectively used to develop a new magic saw.

Warehouses form an important link in a supply chain network. Among a variety of activities in warehouses, order picking is the process of retrieving a number of items out of storage to meet customer orders. Today, as the transactions through direct sales are wide spread, warehouses often receive a large amount of small orders to be handled within tight time windows, which makes fast and efficient order picking more important than ever. This paper examines a new order picking method where the concept of bucket brigade (BB) is applied. Bucket brigade is a way of dynamically coordinating workers who progressively perform a set of operations along a flow line. In bucket brigades, a worker is not assigned his jobs in a static way. Each worker takes a job from his predecessor when he is free. We identify some considerations when bucket brigades are applied to order picking activities. A new BB picking protocol is presented to improve existing BB picking protocols. Through simulation experiments, the performance of BB order picking is evaluated under various logistics environments.

Most industrial accidents occur when the workers' unsafe behavior and the unsafe situation of workplace take place at the same time. Although human's unsafe behavior is indispensable to work field, the evaluation scheme to detect the causes for the accident resulted from human's unsafe behavior and counterplan should be prepared to prevent and reduce accident. To do this, we first classify the specific background factors in terms of human inner factor and environment factor and then develop the AHP (Analytic Hierarchy Process) model to analyze the background factors that affect the worker's unsafe behavior. We also develop a checklist to be able to evaluate the occurrence possibility of individual worker's unsafe behavior.

This study is plan to show what kinds of problems we have and how we can overcome problems about occupational safety and health education and training system in Korea, Some features which advanced countries had were found and characterized as follows; First, advanced countries realized the importance of safety and health education on the role of preventing accident and they had varieties of training and education programs on the industrial safety and health for employer and worker. Second, there were many safety and health education programs and grants which especially focused to the small businesses. Third, they had also several programs to induce employer and worker's concerning about the safety and health education voluntarily, In conclusion, we introduced some inducing models, and proposed to revise contents of the education programs and to increase participation of other parties in safety and health education market so that could vitalize our safety and health education and training.

Nowadays, Industrial competition power is depended on that rapidly produce the customized products. Therefor, it is necessary to reduce period of product development. Thus, concurrent engineering that work many process at a time was appeared and Rapid prototyping was appeared, it is method that rapidly produce the prototype. If the graphic model was made by CAD, the prototype can be made in short term. That provide what the part was directly tested by the worker. It provide a worker with believable data. We study on the influence of surface roughness on injection interval and part angle at FDM.

산업 현장에서 작업자의 잘못된 작업행동으로 인한 안전사고가 꾸준히 발생하고 있다. 현재는 관리자가 육안으로 작업자의 위험행동 여부를 관리하고 있지만, 모든 작업자를 관리자 한명이 관리하기에는 현실적으로 어려움이 있다. 본 논문에서는 이 문제를 해결하기 위해 고소 작업자의 안전벨트에 IoT 장치를 부착하여 행동 데이터를 클라우드에 업로드하고, 딥러닝을 통해 작업자 위험행동 여부를 분석한다. 분석한 결과를 관리자가 쉽게 모니터링 할 수 있도록 하여, 안전사고를 예방하도록 하는 시스템을 설계하였다.

The aim of this study is that HPMA(Hazard Potentials in My Areas) System is to present for establishment of the voluntary safety management on industrial region. HPMA System Itself means that manager, supuryisor and worker on process-line find out the hazardous and/or unsafe potentials from their work places and make the plan of improvement by means of mutual communication with top manager and the department of safety staff, eventually put in the practice. In case that it takes the longer time to improve hazard potentials and is impossible improvement by existing technique, appropriate check-list will be used by the worker himself on the identified production line. Form this system, therefore, it makes them to get more and more sensitivity to the hazards. In this study, we present the voluntary safety management system which is controlable systematically and in the final analysis the direction of safety management by computerization of HPMA System which is activated in their work places.
