Objective: The aim of this study is to analyzing the characteristics of waste collector workers' Work-related Musculoskeletal disorders (WMSDs) in Daegu area and presenting the prevention the WMSDs based on the field survey. Method: We conducted field survey concerning the musculoskeletal discomfort, understanding of WMSDs, symptom parts of the body, having the education of WMSDs, etc. at 48 enterprises, 196 waste collector workers in Daegu area. Results: Musculoskeletal symptoms on shoulder was the highest claimed from 26.7% of waste collector workers, legs/feet was 24.3%, and lower back was 19.2%. Works according to the criteria of musculoskeletal burdened work by the Minister of Employment and Labor in 2011 results were over 'high risk stage' of Task 2, Task 4, Task 7, Task 8, and Task 9 in most waste collecting work. The musculoskeletal discomfort in accordance with Borg's CR 10 scales of main tasks consisted of 7.75 recycle waste collectors, 7.54 living waste collectors, 7.19 large waste collectors, 6.33 food/drink waste collectors, 5.58 street cleaners. Conclusion: This study suggests that it is necessary for waste collector workers to carry out the prevention program of musculoskeletal diseases. And we need to improve their working environment and personal hygiene such as changing working shift, increasing automatic street sweepers operation, and safety and health education/trainning.

애트리뷰트 문법은 언어 분석 시스템(Language-analysis system)과 컴파일러 작성 시스템(Compiler-writing system)의 표현에 가장 널리 쓰이고 있다. 본 논문은 컴파일러 개발자가 컴파일러를 개발하고자 하는 프로그래밍 언어의 정의 형태와 컴파일러를 개발하는데 사용되는 언어의 표현 형태의 차이로 인해 발생하는 어려움을 극복하기 위해서 애트리뷰트 문법(Attribute Grammar - AG)에 근거한 명세 언어(EPANDA)를 제안한다. 명세언어로 작성된 컴파일러를 입력으로 받아 실제 시스템 내에서 실행 가능하고, 동일한 기능을 수행하도록 하기 위해서 범용 프로그래밍 언어로 작성된 컴파일러를 생성해 주는 자동 생성기를 개발하여 컴파일러의 개발시간을 단축시키고, 언어의 확장 및 수정을 용이하게 한다.

Rehabilitation exercises are the treatments designed to help patients who are in the process of recovery from injury or illness to restore their body functions back to the original status. However, many patients suffering from chronic diseases have found difficulties visiting hospitals for the rehabilitation program due to lack of transportation, cost of the program, their own busy schedules, etc. Also, the program usually contains a few medical check-ups which can cause patients to feel uncomfortable. In this paper, we develop a remote rehabilitation system with bio-signals by a stereo camera. A Kinect stereo camera manufactured by Microsoft corporation was used to recognize the body movement of a patient by using its infrared(IR) camera. Also, we detect the chest area of a user from the skeleton data and process to gain respiratory status. ROI coordinates are created on a user’s face to detect photoplethysmography(PPG) signals to calculate heart rate values from its color sensor. Finally, rehabilitation exercises and bio-signal detecting features are combined into a Windows application for the cost effective and high performance remote rehabilitation system.

Objective: This study is aimed at analyzing the characteristics of Work-related Musculoskeletal disorders (WMSDs) from various prospects based on the industrial accident statistics and field survey. The results can be used to develop more effective policies to prevent WMSDs. Method: (1) First of all, for the analysis of a wide view point concerning the characteristics of WMSDs according to industrial accidents statistics in 2008-2010 (i.e. age, gender, working duration, risk factor, etc.) (2) We conducted field survey concerning the musculoskeletal discomfort, understanding of WMSDs, musculoskeletal symptoms, etc. at 48 Enterprises, 196 waste collector workers in Daegu provinces. (3)Also, Working Condition Survey in 2010 conducted comparing with the results, 175 cases. Results: The majority of patients were between 40 and 50 years old(73.9%), male(85.8%), companies with less than 50 workers(38.4%), more than 10 year of working duration(49.0%), and forceful exertions(73.4%). According to Musculoskeletal Burdened Work which was notified by the Minister of Employment and Labor in 2011, high risk task was shown in Task2, Task4, Task7, Task8, and Task9 The musculoskeletal discomfort in accordance with Borg's CR10 scales of main tasks consisted of 7.75 Recycle/Large waste collectors, 7.54 Living waste collectors, 6.33 Food/Drink waste collectors, 5.58 Street Cleaners. Conclusion: These results showed that there were significant characteristics of WMSDs of Waste Collector that could be used as basic data for the WMSDs prevention policy.
