Research on the Problems of Facility Safety Inspections and Solutions for Improvement
Kim, Hak-Eung ; Jung, Soo-Il ;
Journal of the Korea Safety Management and Science, volume 9, issue 4, 2007, Pages 1~9
The Korean government had enacted 'Special Regulation on the Safe Maintenance of Facilities' and carried out regular safety inspections since the mid-1990s, consequently establishing and enforcing an effective maintenance and management system. And throughout this entire process, the government searched for new methods to increase the overall effectiveness of the system. Nevertheless, the reality is that our society remains structurally unprepared to implement a commercial mindset that views the concept of "safety" as a product that can be traded in the open market based on supply and demand. Therefore, the government should establish mid to long-term plans to implement such a system in successive stages.

This study tried to identify the job stress characteristics of female bank workers and the relationship between their stress and symptoms associated with musculoskeletal disorders(MSDs). The total number of 587 female bank tellers have been participated in this study. Specifically, questionnaire surveys regarding job stress and MSDs symptoms were conducted. On the basis of the results from the survey using Korean version of job stress questionnaire with 24 questions, stress scores associated with job requirement and job flexibility were relatively high. The job stress levels regarding job demand, organizational system, occupational climate at the work place were relatively high for the full time workers while the job stress levels regarding insufficient job control, job stability, interpersonal conflict, lack of reward were relatively high for the part time worker. The workers with longer total work years had relatively high job stress associated with interpersonal conflict, and organizational system while the workers with longer work years at the current job had relatively high job stress associated with occupational climate. Also, the workers with longer working hours a day had relatively high job stress associated with job demand, interpersonal conflict, organizational system, and occupational climate. According to the relationship identified in this study, symptoms at the neck, shoulder, hand, low back. leg were associated with the stress levels in terms of job flexibility, interpersonal conflict, job requirement, job stability. In conclusion, female bank workers are exposed to job stress due to their specific job characteristics and there has been certain relationships between their job stress and MSDs symptoms.
Preventing the Musculoskeletal Disorders using Association Rule - Based on Result of Multiple Logistic Regression -
Park, Seung-Hun ; Lee, Seog-Hwan ;
Journal of the Korea Safety Management and Science, volume 9, issue 4, 2007, Pages 29~38
We adapted association rules of data mining in order to investigate the relation among the factors of musculoskeletal disorders and proposed the method of preventing the musculoskeletal disorders associated with multiple logistic regression in previous study. This multiple logistic regression was difficult to establish the method of preventing musculoskeletal disorders in case factors can't be managed by worker himself, i.e., age, gender, marital status. In order to solve this problem, we devised association rules of factors of musculoskeletal disorders and proposed the interactive method of preventing the musculoskeletal disorders, by applying association rules with the result of multiple logistic regression in previous study. The result of correlation analysis showed that prevention method of one part also prevents musculoskeletal disorders of other parts of body.

An industrial injury prevention has a basis on fundamental spirit of human respect rather than only injury prevention in company. The employer should recognize employee as a core part of an industrial management and use as a starting point of safety and health management rather than means of production. There are many reason for unsafety action without safety operation. The reason is no standard safety operation in company or the workers never get a enough education. Standard safety operation is prepared by paper for accurate directions and orders and operators must read the paper to prevent an error of action. Also an essential particular is safety of equipment and machine must be assumed to establish standard safety operation then safety of operations will be possible.
A Study on Performance Evaluation about Safety Work of Railway Employees using AHP
Ryu, Si-Wook ;
Journal of the Korea Safety Management and Science, volume 9, issue 4, 2007, Pages 49~56
It is known that human factors account for 80 percent of all railway accidents. To reduce human errors must be the most efficient shortcut to railway safety. For public transportation employees like railway, the more delicate safety management should be executed in individual level. However, there are rarely efforts to improve safety performance of workers who are the subject operating the railway system. This paper develops a hierarchy model to evaluate the human safety performance in railway industry. To evaluate the model, AHP (Analytic Hierarchy Process) methodology is adopted. The hierarchy model is composed of four levels which are objective, two criteria, specific factors of criteria, and rating scales. In addition, since employees for evaluation are over 10, the pairwise comparisons for rating scales are carried out by the absolute measurement. We explore the applicability of AHP to the performance evaluation of railway safety workers by an example and also investigate the changes of alternatives that are railway employees according to the changes of human characteristic which is one of criteria.

Journal of the Korea Safety Management and Science, volume 9, issue 4, 2007, Pages 57~62
Aerial working platform is recently used broadly in heavy industry and construction field and also the utilization of it is growing. However, the raise of critical incident caused by unskilled operator is increased gradually. To reduce and prevent such incident, the training for operating is essential. It's not easy to cover the requirements for the training with real platform because of the high price of it, safety and weather condition. This paper proposes a simulator for the training based on virtual reality to give the training safely regardless to the weather condition and the simulator is deliverable in lower price than real one. The simulator proposed in this paper is available to be set according to the level of trainee's skill managing and be also applied for the design of general heavy equipment training simulator.

Three major Asian countries, Korea, China, and Japan, shared 18.3% of global GDP and 14.2% of global trade volume in 2005. When considering this number, cooperation of these three countries is very important. Also, it is needless to say that we need efficient international logistics system in Asia. The key point to realize efficient international logistics system is unit load system utilizing pallets and containers. To build up efficient logistics system among Korea, China, and Japan, we need 'total palletization' with standardized pallets. We may regard 'total palletization' as an 'efficient highway of North-Eastern Asia logistics.' In this study, we will suggest two kinds of effects, which logistics standardization among Korea, China, and Japan will make. One is the effect on economy and trade, and the other is the effect on logistics business and environments.

In most recent years, the business competition has spreads over all fields of corporations and their management area regardless of time and place, which makes the survival environment of each enterprise fiercer. In order to secure a high position in the competitive market, the various firms has implemented many methods related to price, quality, and service efficiency. However, the implementation with only low price or high quality might be helpless to hold a high position in modem market. Moreover more attention should be paid to the internal business processes of an organization. Therefore, a new and different method should be searched or developed in order to win the competitive power among other enterprises. This research will focus on the improvement of the business processes within the non-manufacturing industry by applying Lean Six Sigma methodology. DMAIC method will be applied to improve the inbound and outbound logistics processes, manage the inbound and outbound vehicles, and control the receiving and shipping activities.

Journal of the Korea Safety Management and Science, volume 9, issue 4, 2007, Pages 121~127
CSP(Concurrent Spare Parts) is supplied with the procurement of new equipment or weapon system and is used to sustain the equipment without resupply during the initial coverage period. This study is concerned with a problem of determining the near optimal inventory level of the spare parts, especially Concurrent Spare Parts. For this, we utilize the mixed periodic and continuous review polices considering the CSP and (r,Q) Policies concurrently in a two-echelon distribution system. We propose the mathematical model to minimize the total cost which is composed with ordering cost, purchasing cost, holding cost, and stickout cost. If the mixed policy is compared to other policies(CSP, (r,Q)), the proposed methodology performs well and is best policy in the equipment maintenance expenses.
