Every organization needs to maintain its long-term effectiveness through the positive perceptions, attitudes, and behaviors of its members. Customer orientation, job satisfaction, and organizational citizenship behavior (OCB) are the important functioning aspects for the long-term organizational effectiveness. The purpose of this study is to investigate the impact of service-worker's customer orientation on OCB within Korean bank and insurance sector by analyzing the relationship of constructs in the conceptual model. To achieve research objectives, survey method is employed. Findings of this research reveal that both need and enjoyment dimension of CO are very important in predicting OCB. We sent 220 questionnaires to service workers of the bank and insurance then received 200 valid responses. The research was conducted in bank and insurance agency in J city. The choice of these two types of organizations was dictated by the fact that they have large number of service worker with diverse background at multiple levels in these industries. Results also indicated that the moderating effect of pay satisfaction on the relationship between their OCB and CO had a weak effect.

The purpose of this study was to investigate the effect of risk awareness on injury experience in quick delivery service workers. Risk awareness has complicate characteristics such as its level of worker and worker's decision about the level of other's risk perception. Data were collected by interview survey with structured questionnaire about injury experience, risk perception, work characteristics, and socio-demographic characteristics of quick delivery service workers by cross sectional survey design in 2012. The sample size was 120 respondent of quick delivery service workers. Statistical method for this study was hierarchical logistic regression method with 3 different models using socio-demographic characteristics and work characteristics and risk perception, etc. The difference between the level of risk perception of quick delivery service and other's was statistically significant effect on the experience of injury. Especially the higher the level of risk perception of quick delivery service workers is than other's, the lower the injury experience of quick delivery service worker is. The limitation of this study can be found in survey design. The future study for investigation of mechanism of the combined effect of risk perception of quick delivery service workers and others on injury experience.

Purpose: This paper proposes a method detecting the falling of a maintenance worker in the underground utility tunnel, by applying deep learning techniques using CCTV video, and evaluates the applicability of the proposed method to the worker monitoring of the utility tunnel. Method: Each rule was designed to detect the falling of a maintenance worker by using the inference results from pre-trained YOLOv5 and OpenPose models, respectively. The rules were then integrally applied to detect worker falls within the utility tunnel. Result: Although the worker presence and falling were detected by the proposed model, the inference results were dependent on both the distance between the worker and CCTV and the falling direction of the worker. Additionally, the falling detection system using YOLOv5 shows superior performance, due to its lower dependence on distance and fall direction, compared to the OpenPose-based. Consequently, results from the fall detection using the integrated dual deep learning model were dependent on the YOLOv5 detection performance. Conclusion: The proposed hybrid model shows detecting an abnormal worker in the utility tunnel but the improvement of the model was meaningless compared to the single model based YOLOv5 due to severe differences in detection performance between each deep learning model

While Korea had achieved radical growth of construction industry, it also had accumulated problems in material, human and economical loss due to its low quality of safety level. Therefore, not only enterprises but also the nation is putting in a great deal of efforts for construction safety. However, its effect is not satisfiable. This research aims for change of construction cite by introduction of professional Safety Patrol Management System(SPMS) and consideration of its necessity. To consideration of its necessity, we compared and anaylzed average numbers of indicated dangers and safety accident incidences in each construction cites and we researched changes in worker's safety sense. It will establish the suitable design standards and suggest the basic database for estimating disaster and accident ratio.

Objective : World Health Organization and International Labour Organization, in June 8, 1999, requested that working conditions should be reformed ethically right and economically solid for 2.7 billion world labour force. The purpose of this study is to request compensable surgical therapeutic options and to suggest the renewal in cognizance criteria for worker's compensation, especially in spondylolisthesis. Methods : Regarding spondylolisthesis, we obtained data from Korea Labor Welfare Corporation(KLWC). Spinal disease occurrence incidences and medical fees of National Federation of Medical Insurance(NFMI) were analysed. The compensated 122 spinal instrumented cases included 117 male and 5 female patients, aged from 23 to 72 years old(mean : $45{\pm}9.85$). We compared Korean and Foreign Workers Compensation Law. Results : Numbers of herniated nucleus pulpus(78 cases), spinal fractures(34 cases) and dislocations(4 cases) were claimed after spinal interbody fusion operation and were compensated. These compensated degenerative diseases, work related illness, occurred in the course of work. A case of 52-year old spondylolisthesis patient with Disability Grade 8 was compensated by KLWC, according to its occurrence at work by accident. With exception of trauma at work by accident, current cognizance criteria were too narrow to be compensable, especially in surgical therapeutic option, for worker's spondylolisthesis. Conclusion : Considering both worker's compensation law and clinical pathologic progress, we believe that spondylolisthesis should be regarded as a compensable occupation related disease if and when aggravates rapidly in the course of work. We suggest a new cognizance standard to KLWC for labour welfare and proper worker's compensation.

Recently, there have been active researches about the VPCS (Virtual Parallel Computing System) based on multiple agents. The PVCS uses personal computers or workstations that are dispersed all over the internet, rather than a high-cost supercomputer, to solve complex problems that require a huge number of calculations. It can be made up with either homogeneous or heterogeneous computers, depending on resources available on the internet. In this paper, we propose a new method in order to distribute worker agents and work packages efficiently on the VPCS based on the IBM Aglets. The previous methods use mainly the master-slave pattern for distributing worker agents and work packages. However, in these methods the workload increases dramatically at the central master as the number of agents increases. As a solution to this problem, our method appoints worker agents to distribute worker agents and workload packages. The proposed method is evaluated in several ways on the VPCS, and its results are improved to be worthy of close attention as compared with the previous ones.

This paper proposes a system that utilizes USN(Ubiquitous Sensor Network), Bluetooth and smart phone to improve the function of senior houses. In typical approach, a system in a senior house either directly accesses the status of elderly people by its sensor or is alerted by elderly people who trigger an emergency bell, derive a decision and take an appropriate action. In addition, it is possible for a designated social worker to check the status of senior patients through monitoring system connected by UTP(Unshielded Uwisted Pair) cables, but the responsible person has to be present to monitor patients' status. However, the new system, suggested in this paper, embed Bluetooth function in a blood pressure gauge, thus the smart phone receives patients' health information such as blood pressure through Bluebooth, if any abnormal event occurs. Consequently, the smart phone sends SMS(Short Message Service) to a responsible social worker or a designated hospital. When this program in the paper becomes a reality, an unmanned system that is able to determine suitable actions for certain events will be established, even if a social worker were absence.
