The overall goal of a safety based railroad system is either to eliminate hazards in designing or to minimize the possibility of it. In order to indicate system safety or low risk although it may not be possible to achieve zero risk conditions, first, it shall ensure that any disasters would occur due to system operation because the prescribed specifications are properly fulfilled and there are no failures of any kind. Second, the risk of faults or failures leading to a mishap must be eliminated or minimized by using fault-tolerance or fail-safe procedures. This paper will attempt to summarize the personal and social risk criterion at widely scattered points, presently used as a safety approach in all over EU, in order to establish the step by step procedures of the detailed standard for railway facilities. In addition, we present the new safety analysis method using the SIL-based evaluation standard and the Reachability Graph of the Petri Net.

Journal of the Korea Safety Management and Science, volume 13, issue 3, 2011, Pages 19~28
The efforts to reduce industrial accident has been brisk recently in workplace. These efforts were mainly concentrated on construction and manufacturing. Despite these efforts, current accident rate so far has been maintained on the fixed level. According to the change of industrial structure, the government's attention on industrial accident prevention activities are focused in service industries. When trying to appraise the result of such activities, it is impossible to evaluate safety without certain criteria. Therefore, we analyze data by TOPSIS method that all the subway institution jointly manage every year. we decide the order of safety priority between domestic subway workplaces and measure the variation in safety by sensitivity. As a result, we draw conclusions to improve safety for the primary consideration and suggest alternatives.

Safety and health related information for the proper use and handling of pesticides is usually printed on the surface of the pesticide products (bottle type or bag type) in the form of texts. But, the guidelines or standards for the appropriate presentation of the texts for the pesticide products are most vague or not practical. Thus, this study aimed to provide the preliminary guidelines for the text sizes based on the legibility experiments. Total twenty subjects from two age groups (young: n=10, old: n=10, five males and five females in each group) participated in the experiment. First, subjects read the text cards presented in the distance of 50cm from the eyes of the subjects. Eight different text card sets were prepared for different font type(thick gothic-type and fine gothic-type), thickness of font(plain and bold), and number of syllables (2 and 3 syllables). When subjects read the cards, the correctness of reading (correct or wrong) was recorded and the degree of discomfort (from 1: no discomfort at all to 4: can't read at all) was also evaluated for all the text sizes. Results showed that the character size should be 4 pt or larger for the young subjects to read at least one word correctly in all the text conditions. For the old subjects to read at least one word correctly, the character size should be five pt or larder. The average of the minimum character sizes for 100% correct answer is 6.1 pt for young subjects and 10.5 pt for old subjects, respectively.

Choi, Sung-Woon ;
Journal of the Korea Safety Management and Science, volume 13, issue 3, 2011, Pages 45~53
The research proposes seven elimination rules of redundant gates and blocks in Fault Tree Analysis (FTA) and Reliability Block Diagram (RBD). The computational complexity of cut sets and path sets is NP-hard. In order to reduce the complexity of Minimal Cut Set (MCS) and Minimal Path Set (MPS), the paper classifies generation algorithms. Moreover, the study develops six implementation steps which reflect structural importance (SI) and reliability importance (RI) from Reliability Centered Maintenance (RCM) that a priority of using the functional logic among components is to reduce (improve) the system unavailability (or availability). The proposed steps include efficient generation of state structure function by Rare Event Enumeration (REA). Effective use of importance measures, such as SI and ill measures, is presented based on the number and the size of MCS and MPS which is generated from the reference of this paper. In addition, numerical examples are presented for practitioners to obtain the comprehensive understanding of six steps that is proposed in this research.

Journal of the Korea Safety Management and Science, volume 13, issue 3, 2011, Pages 55~61
Unit cost for asbestos removal work which have been made out at government contract award for recent three years has been reviewed and shown with table. And the cost have been compared with ones made out by two agencies, American asbestos removal specialists, government ministry for making out comparison tables. First, legal and practical work status survey have been made to determine reasonability of introducing separate contract-awarding system, as a part of ensuring reasonable unit work cost. And then, two different status have been compared and there in introduction possibility of separate contract-awarding system, it is found out. In interior removal work case, it is thought that 50% by owner, 60% unit work cost by the expert of which removal specialist think as reasonable unit cost. the results for exterior and spray work method are shown with almost same context. Impact factors for determining unit work cost such as project mount, project kind, contract-awarding method, subcontract method have been compared with parties. Removal specialist and expert group have almost same ideas for project amount which has been hightestly weighed but owner's recognition has partially lower than specialists idea. There are almost no difference of recognition between three(3) parties for project kind. Idea comparison of reasonable unit work cost for asbestos removal work between three concerned parties has been analyzed and found out that expert group do unit work cost, 65% of which removal specialists estimate, in interior tex removal. And there is almost no difference between them in exterior roof slate removal. But there is considerable difference between them that owner estimates 50% unit cost of specialist one while expert group estimate 50% of specialist idea of unit removal cost.

Seo, Kwang-Kyu ;
Journal of the Korea Safety Management and Science, volume 13, issue 3, 2011, Pages 63~69
As environmental protection is becoming more and more important, green production has become a key issue for almost every manufacturer and will determine a manufacturer can be sustainable in the long term. Therefore a performance evaluation system for green suppliers is necessary to determine the suitability of suppliers to cooperate with the company. While the works on the evaluation and/or selection of suppliers are abundant, those that concern environmental issues are rather limited. The objective of this study is to construct a combined model based on fuzzy analytic hierarchy process (FAHP) and balanced scorecard (ESC) for evaluating green suppliers in the manufacturing industry. The ESC concept is applied to define the hierarchy with four major perspectives (i.e. financial, customer, internal business process, and learning and growth), and performance indicators are selected for each perspective. FAHP is then proposed in order to tolerate vagueness and ambiguity of information. Finally, FAHP is finally constructed to facilitate the solving process. With the proposed model, manufacturers can have a better understanding of the capabilities that a green supplier must possess and can evaluate and select the most suitable green supplier for cooperation.

Journal of the Korea Safety Management and Science, volume 13, issue 3, 2011, Pages 107~114
Traveling salesman problem is to minimize the total cost for a traveling salesman who wants to make a tour given finite number of cities along with the cost of travel between each pair them, visiting each cities exactly once before returning home. Traveling salesman problem is known to be NP-hard, and it needs a lot of computing time to get the optimal solution, so that heuristics are more frequently developed than optimal algorithms. This study suggests a hybrid parallel genetic algorithm(HPGA) for traveling salesman problem The suggested algorithm combines parallel genetic algorithm, nearest neighbor search, and 2-opt. The suggested algorithm has been tested on 7 problems in TSPLIB and compared the results of existing methods(heuristics, meta-heuristics, hybrid, and parallel). Experimental results shows that HPGA could obtain good solution in total travel distance minimization.

It seems required to determine what might affect the technological innovation activities of manufacturing companies and what kind of role they could play for them to carry out technological innovation activities in an effective way. The objective of the present study is thus to conduct a depth empirical analysis of the structural relations among business environment, technological innovation activities and performance of manufacturing companies. From the analysis, following outcomes could be drawn: First, with regard to the relationship between business environment and technological innovation activities of manufacturing companies, it has become clear that the external environment is a factor that can influence technological innovation activities such as management of technical property, technological innovation system as well as technical network, while it exercises no impact upon adaptation of manufacturers to new technologies. The internal environment, on the other hand, turns out to have influence on such overall factors of technological innovation activities as management of technical property, technological innovation system, adaptation to new technologies and technical network; and Second, as for the relationship between technological innovation activities and their performance, it has been obvious that management of technical property and technological innovation system, both factors of technological innovation activities, affect the performance of product development and financial achievements of manufacturing companies. Their adaptation to new technologies will also affect their performance of product development as well as financial achievements. These findings suggest that it is important for manufacturing companies to set up an operating system that may be able to upgrade the practical applicability of their technological development activities in an attempt to promote performance of their technological innovation activities.

Kim, Kyung-Jong ; Seo, Jong-Hyen ;
Journal of the Korea Safety Management and Science, volume 13, issue 3, 2011, Pages 175~182
The purpose of this article is to suggest what is the desirable direction of economic relationship between Korea and China. The economic relationship between countries is based on how the present network is. As the economic relationship between countries grows, the network between countries will expand. In the past, the economic relationship between Korea and China is cooperative one from the viewpoint of international division of labor. Korean industries was focused on the value-added and mid-advanced technology products, while Chinese was focused on the labor-intensive products. As the China's economy grows for more than thirty years, there is a great change in China's economic policies and environment. China's industry structure is moving from the labor-intensive industry to technology-oriented industry. China's exports to the global market is increasing very fast, and China's domestic market is also growing. The change in Chinese industries' structure bring about severe competition in the global market. The expanding China's domestic market is also good opportunity as the new market in the world. The change in China's industrial structure needs for Korea to establish the 'New Network" between two countries. Korea has to grab the new opportunities in the China's domestic market and find new cooperative network with the products and industries.

Nowadays, many countries have strived to promote prospective industries and occupations at the national level under the global circumstances such as green growth, job creation and so on. For this reason, the decision making method for qualifications foresight which will be available for the mentioned category-prospective industry and occupation- is required for it's feasibility. Pilot surveys on future workforce demand and promotion policies on service industries which are selected as a prospective industry or occupation by government parties were conducted through this research. Based on them, available qualifications-including not only national(skill) qualification but also private qualification- which can be created for prospective industries and occupations related to green growth and job creation were predicted. On the other hand, observing the change of service industry, occupation and qualification abroad, this research attempts to present the decision making method for verifying the decision' validity on qualification in Korean service industry and related occupation. Applying multicriteria decision making, a preference was examined for checking the validity of the created qualifications by prospective service industries and occupations in both sides-experts and laypeople. Based on it's result, the research was conducted regarding a validity of new qualifications in prospective industries and occupations.

Environment standards can be used as a foundation of environment administration (specific expression of political goals or quantitative evaluation standards of political effects). When environment adminstration improves severe air or water pollution rapidly, the environment standard can work effectively to show the goals specifically and clearly. The environment index which is designed to evaluate environment systems, should be established to express the environment system generally. To realize sustainable development, the sustainable indexes usually consisting of these three areas in that harmony of environment, economy and society are required. In this research, sustainable environmental indicators to understand the characteristics and to compare likes theme of environmental conditions in international and national level indicators, regional environmental management plan to promote the management by objectives are to provide the basic data. It is desirable for the environmental policies to work harmoniously with direct control, use of economic means and voluntary methods. Regarding the evaluation of environmental index, the action results of civilian's or individual's activities are needed to be reflected into the evaluation.

Currently, 10% of the domestic aircraft accidents and 9% of delays and cancellations were generated due to poor maintenance. Aircraft maintenance work is divided into works in material warehouse and in hangar. In material warehouse, the problem in aircraft maintenance work is occurred when the serial number of parts are identified and entered. In hangar, work order are duplicatively written. In addition, the maintenance information is not shared and then work order is wrong delivered. In this study, we analyzed the maintenance process and the informations that occurs in the material warehouse and hangar for large airline company to solve the problems. And serial numbers are replaced by QR code. And documented work order and manual are handled using the tablet PC. In conclusion, this paper studied smart work of maintenance process about tire parts. We expect to improve the inefficiency of identification of serial number and total maintenance time is reduced by real-time information sharing.
