  • PSM(process safety management), introduced for the purpose of managing complex chemical processes, has contributed to the prevention of chemical accidents, but has recently revealed its limitations. Recently, major industrial accidents have increased, and in particular, Serious Industrial Accidents have increased rapidly in non-routine works since 2020. It is time for an effective PSM operation plan. This study examined that FRAM can be effectively used in the PSM operation process by using FRAM (Functional Resonance Analysis Method), a useful technique for understanding and predicting human error and accident occurrence processes by modeling nonlinear and complex interactions, to analyze accident cases that occurred in non-routine works, and to further analyze the process of performing general PSM non-routine works.

  • The raw materials for plant-stalk-folkcrafts are cultivated in the whole country. Most Korean farmers, to increase their income, have produced mats and containers with various plants as a side line from very long ago. At first, they began from the instruments of life and then made folkart and at last get to manu\ulcornerfacturing of industrial folk craft. The folkcrafts, made of plant-stalk, which could nor conform to changing society, are partly declined and partly handed down as the traditions. The social change today, however, makes living conditions more speedy and multisided, accordingly the characteristics of demand also become in\ulcornerdividual and various. While the demend is various like this, suppliers cannot answer demendants' requirements, and consequently, the demand and profit cannot be increased. According to this, the purpose of this study is set up to give an answer to the situation that is at the traditional standstill, through an examination of the motives. I. The crafts of plant-stalk are made only in an organized relationship between agriculture, industry and art as it is compounded art of gathering raw material, manufacturing, producing, improv\ulcornering design and production conditions. It may be possible that a farmer gathers material and weaves it manually but in others, it is im\ulcornerpossible to refine, bleach and dye because the process requires a professional industrial treatment. It is impossible to make art works to a farmer as every farner does not always have aesthetic sense. Though a farmer or producer has these all abilities, it is not desirable to him from economical view. 2. The development or improvement is essential in many sides but the most important thing seems to he in design. According to reports, it is, howevt!r, fact that the crafts improved in design of existing works have more expanded the sales than newly developed works. Therefore, ir appears advisable to improve designs of existing things positively as they have merit of occupying a position already, but on the other hand, new crafts have to be also developed and the producer should grasp the proper time. 3. Building up an industrial complex to improve design with collecting the producing districts for this works scattered allover the country is very desirable for speedy communication, intensive educa\ulcorner tion or training, and effective guidance. 4. In producing for export abroad, before everything, must know the life environment, custom! and manners, main thought of the country, and then produce according to these. S. The crafts of plant-stalk are the fIrst industry in present but in the futher it should change intc second or third industry. 6. A synethetic organization for supporting side line should be established for effectiveness, and experts have to be secured and also the educational-industrial complex and activation of study should be preceded.

  • In order to achieve stable and efficient use of energy at iron and steel works, a model for the prediction of supply and demand of electric power system is developed on the basis of the information on operation and particular patterns of electric power consumption. The optimal amount of electric power to be purchased and the optimal fuel allocation for the in-house electric power plants are also obtained by a mixed-integer linear programming(MILP) and a nonlinear programming (NLP) solutions, respectively. The validity and the effectiveness of the proposed model are investigated by several illustrative examples. The simulation results show the satisfactory energy saving by the optimal solution obtained through this research.

  • This study proposes a new framework for designing disassembly methods. In recent years, environmental problems have become global issues. Recycling of used products or resources is recognized as a matter of significance since it may help reduce the risk of exhausting natural resources. Considering possible exhaustion of limited natural resources in the near future, reuse of products would gain more environmental significance. As yet, it relies hugely on manual disassembly, which labor cost places burden on the total recycling cost. The purpose of this study is to propose a methodology designing for manual disassembly works, and a creation method of a jig. By focusing on parts' connection and attachment relationship, parts are categorized in 5 categories (parent part, joint key part, attaching key part, child part, and independent part) according to the features that parts possess, and 3 kinds of connection relationships (parent part-joint key part connection, parent part-independent part connection and child part-child part connection) are clarified. Connection relationship and attachment relationship charts have also been created, and utilizing them, disassembly orders are settled, and a disassembly jig is devised. The proposed methodology is also applied to a real product and its work time is improved 42% form 31 to 13 seconds.

  • Unlike production line works, construction work is non-repetitive in nature. In this study, a checklist was developed to characterize the ergonomic hazards of construction work. Eight existing checklists including OWAS, RULA, and REBA were integrated, and a new version was designed to include more postures of lower extremities. The analysis results obtained using the new checklist showed that manual materials handling (MMH) is the most common risk factor. About 62% of the MMH was done below the knee level or above the elbow level, and 22% was carried out with the trunk twisted more than $60^{\circ}$. The next risk factors were the works done with the knee bent or squatted, or with the shoulders abducted. It can be concluded that the new checklist is successful as a quick and easy tool for screening risk factors of construction works, although it is not capable of determining action levels. Further studies on validation of the checklist are expected.

  • Objective: This study aims to investigate the effects of organizational support, risk perception and job satisfaction on safety consciousness in confined space works. Background: Confined space works are rated as hazardous works with high injury frequency and fatalities. But there were few researches for the occupational injury of the confined space workers. Method: Questionnaire survey targeting 236 workers working in confined spaces were carried out to construct the structural equation model on safety consciousness. The participants were all male workers, and they install and maintain or clean facilities mainly in the confined spaces. Results: A structural equation model for safety consciousness was proposed, and validated based on perceived organizational support, risk perception and job satisfaction factors. Perceived 'organizational support' contributed significantly to 'worker's safety consciousness' both directly and indirectly. Also, perceived 'worker's safety consciousness' was also affected by perceived 'job satisfaction' and 'risk perception'. In terms of magnitude of relationships, the direct effect of perceived 'job satisfaction' on 'worker's safety consciousness' was the greatest among the interrelationships among latent factors. Conclusion: Workers' safety consciousness can function as a leading indicator for safety and hazard prevention of workers. Application: The results can be used in developing safety prevention programs for confined space workers.
