Purpose: This study aimed to investigate the effect of an intensively rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. Methods: In this study, the anonymized electronic medical records of individuals who participated in the intensive rehabilitation program (among those who were admitted to the hospital belonging to the Labor Welfare Corporation) due to an industrial accident from August 2018 to September 2019 were collected. As a result, the records of 12 subjects meeting the screening criteria were analyzed. Results: According to the time of application to the intensive rehabilitation program, the 10 Meter Walk Test (10MWT) (p < 0.01), Berg Balance Scale (BBS) (p < 0.01), Timed Up and Go Test (TUG) (p = 0.01), the L Test of Functional Mobility (L-test) (p < 0.01), Prosthetic Limb Users Survey of Mobility (Plus-M) (p < 0.01), and Houghton Score Question (HSQ) (p < 0.01) values significantly improved with time. Conclusion: This study confirmed the positive effect of an intensive rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. However, this study was limited by the absence of a control group, and, thus, it highlights the need for more extensive research with a large sample.

Objectives : DAMA cases were analyzed to examine what the main casual factors of DAMA were and how to deal with these cases effectively in hospital with the DAMA interdisciplinary team including medical social worker whose role is to perform psycho-social assessment, family counsel, to evaluate family's DAMA need. Patients and Methods : The content analysis of medical record and social work record were reviewed in 37 cases referred by medical doctor to DAMA team. These cases were reported by patients' self discharge request or family's request for discharge from September 1998 to February 2000. The DAMA team consists of Assistant Director of Hospital as team leader, medical staff in-charge, social worker, QI nurse, other staff members who are not involved in direct treatment for patient, and administrative clerk. Results : The results of content analysis are as follows : 1) The most causal factors of DAMA consist of combination of more than 2 factors. 2) The major decision-maker is revealed to be son and daughter of patient. 3) In 59.4% of cases, family was not informed of patients' prognosis, alternatives, the consequence of DAMA at all. 4) In cases of DAMA report, the rapid intervention of social worker is carried out. Conclusion : In this study, we propose the interdisciplinary team approach to make decision legitimately and ethically for DAMA. The suggestions from this study are as follows : 1) To deal with DAMA case properly, the interdisciplinary team approach should be considered. 2) The criteria for DAMA case should be formed carefully. For the explicit selection of DAMA case, preliminary system for high-risk patient screening is recommended. 3) The medical social worker is available for the psycho-social problems of the patient once family members. For the effective family counselling, discharge planning and nursing home placement, the participation of medical social worker should be mandatory.

A respirator is useful to protect a worker from the harmful gases and vapors in the workplace, and the evaluation of respirator cartridge service life is important for the worker's health and safety. The performance of cartridge is effected by several factors such as concentration of gas and vapor, humidity, temperature, adsorbents and cartridge packing density. Adsorption model was applied to both sampling tube and respirator cartridge to predict the service life for organic vapors. The variables of the adsorption model were measured from the experiment with the sampling tube, and it was used to predict the service life of respirator cartridge. In the experiment, we used carbon tetrachloride as a organic vapor and activated carbon take out respirator cartridge as activated carbon. As a result, it was possible to predict the service life of respirator cartridge and predicted service life was quite correct. Breakthrough time decreased with increase of CCl4 concentration. In case of sampling tube, adsorbed amount of CCl4 was larger than respirator cartridge due to linear velocity. Also, rate constant of sampling tube was larger than respirator cartridge, because of, effect of flow rate, packing density. In the prediction of service life of respirator cartridge by using sampling tube, the time required for 50% contaminant breakthrough(${\tau}$) is more effective than the rate constant(k').

Recently, industrial accidents have continued to increase due to the industrialization, and worker safety management is recognized as essential to reduce losses due to hazardous factors at work places. To manage the safety of workers, it is required to apply customized safety management artificial intelligence technology that takes into account the characteristics of industrial sites, and a service for real-time risk detection and response to workers depending on the situation based on safety accident types and risk analysis for each task and process. The proposed safety management service consists of worker devices to acquire sensor data, edge devices to collect from IoT-based sensors, and a voice chatbot to support workers' disaster response. The voice chatbot plays a major role in interacting with workers at disaster sites to respond to risks. This paper focuses on real-time risk response using an IoT-based system and voice chatbot on a server for work safety according to the worker's situation. A Scenario-based voice chatbot is used to process responses at the edge level to provide safety management services.

For Web server implementations, there are 4 main schemes: process-per-request (PPR), thread-per-request (TPR), worker thread pool (WTP), and worker thread pool with buffers (WTPB). This paper compares performance of the schemes in response time point of view. WTPB shows the best performance. The appropriate number of worker threads for WTPB depends on the request service time. For short requests, the number can be very small. But for longer requests, it is about 1/6 of the number of simultaneous connections.
