The Optimal Parameter Decision of
carotene Mass Production Using Taguchi Method
Journal of the Korea Safety Management and Science, volume 2, issue 3, 2000, Pages 27~36
The Robust Design method uses a mathematical tool called orthogonal arrays to study a large number of decision variables with a small number of experiments. It also uses a new measure of quality, called signal-to-noise (S/N) ratio, to predict the quality from the customer's perspective. Thus, the most economical product and process design from both manufacturing and customers' viewpoints can be accomplished at the smallest, affordable development cost. Many companies, big and small, high-tech and low-tech, have found the Robust Design method valuable in making high-quality products available to customers at a low competitive price while still maintaining an acceptable profit margin. A study to analyze and solve problems of a biochemical process experiment has presented in this paper. We have taken Taguchi's parameter design approach, specifically orthogonal array, and determined the optimal levels of the selected variables through analysis of the experimental results using S/N ratio.
Productivity Improvement Through the Knowledge Management System Focused on End-user
Journal of the Korea Safety Management and Science, volume 2, issue 3, 2000, Pages 37~46
A company needs low cost and high efficient S/W tools to improve the white color productivity in daily operation, These needs may be satisfied by end-user knowledge management system to be suggested in this paper. We suggest that the end-user knowledge management is not made by specialized developer but directly made by end-users of some related managers using company-wide DB and department DB. We expect that this end-user knowledge management system will increase the efficiency of end-user daily operation and minimize the total life cycle cost of end-user computing system in industry. The suggested end-user knowledge management system has been tested in some companies through the training course.
A Study on Design by Customers for Mass Customization Products
Journal of the Korea Safety Management and Science, volume 2, issue 3, 2000, Pages 47~59
Producing what customers need with near mass production efficiency, or mass customization, has been a major trend in industry. Effective definition of customer requirements is a pre-requisite for realizing mass customization. The new method, called "Design by Customers", is proposed. The proposed method is an approach for companies to communicate to customers about what the company can offer, to find out customer needs, to assist customers in making choices and to negotiate for agreements. In this paper, the design and manufacturing capabilities in making company are represented in a Product Family Architecture. Adaptive Conjoint Analysis is then applied help customers assert their needs, defined variations from base product, visualize their options and assess alternatives. A power supplier of a electronic appliance is shown as an example to demonstrated the suggested method.ed method.

In this research, the system is assumed to carry a single item of which the demand types vary. Demand type is defined as a management's classification of the item according to the demand source or to the service purpose. The purpose of this research is to find the optimal inventory control policy when the system carries a single item which consists of multiple demand types. In this research, the optimizing algorithm contains a heuristic, therefore, the optimal is not guaranteed by the algorithm. At least, this research provides the solution to the problems that have not been solved by the existing algorithms.
Comparative Study and Field Investigation of Korean Industrial Safety Managers
Journal of the Korea Safety Management and Science, volume 2, issue 3, 2000, Pages 89~100
About one hundred twenty thousand (
twenty thousands) people are wounded and about two thousand persons are dead from industrial accidents in Korea ［1］, Therefore, Korea is notoriously called as a haven of disaster. This study investigated the safety situation of industries and attitude of safety managers to reduce the occurrence of accidents. The period of investigation was during March through August, 1977. Two hundreds of safety managers were replied, but replies of 183 were used because some of them were inappropriately answered for the questions. Their replies were analyzed by SAS program. As a result, only three persons out of 183 managers were women, 83% of them are married, 25.1% were graduated from university, 15.2% were graduated from two-year college. Full time safety managers were only 8% of them. Safety managers who have experienced injured before their current position were 26.3%. This confirms that company allocated injured persons to a safety department. Korea also needed an educational agency like NIOSH and a punishment agency like OSHA in USA［5］. These agencies can solve a fundamental problem of safety management for small-and-medium size industries. Furthermore, a new safety management bureau for controlling these two agencies will be necessary to reduce accidents in near future.
A Study of Current Accident Situation for Hotel Service Workers
Journal of the Korea Safety Management and Science, volume 2, issue 3, 2000, Pages 101~115
Whenever a disaster occurs, people emphasizes that "Safety management is most important thing in the company". However, a situation of safety management is not changed dramatically after accidents in the past. Many small-and-medium sized industries neglect the importance of safety management. Current situation can be easily figured out when looks up an occurrence rate of accident, accident frequency rate and intensity rate. This paper investigated what workers of hotel-related industries think of a safety and types of accidents, effect of a safety education. On-site-survey was conducted for actual workers in four deluxe hotels and one condominium. 207 persons out of 400 people were replied. Statistical analysis was performed with SAS package about their reply. In injured type, cut from knife was most frequent. Main cause of accident was a unsafe posture and a unsafe behavior, so more safety education for these workers are necessary. In a physical pain which related with job, chronical pain was most dominant. As a result, a safety education has a high correlation with an experience of injured and treatment of safety, Cooking department has highest occurrence of accident than any other departments. Workers with an experience of five to ten years have most lowest treatment of safety, aid of safety education, safety feeling of their working environment, so peer attention must be put on these people to reduce accidents.accidents.
