  • The purpose of this welding process of the exclusive welding-machine using welding torch-rotation type is to develop a mechanism which can solve the problem of twisting of welding wires and cables. The technique was developed by revising the torch position and smooth controlling of both the normal and reverse rotation. Some of the advantages of using the torch-rotation type apply to the work-rotation technique are the practical uses of increased work space and link work with the factory automation system. Do apply the welding process, I designed and made a special unit so called torch part in order to solve the problems of kinematical. And I made a control panel which can manipulate the progress of the entire process at the work shop. Even if it will be applied to another kind of axle casing's welding work, this process can be utilized if other sizes of the fixed pin and work part is produced and changed. The development of this exclusive welding-machine could reduce the manpower of skilled welding labor and increase productivity and better quality product in comparison to the handmade product.

  • Subsequent to major changes in workplace such as communication method, uncertain organizational environment, and globalizaiton, several studies in workplace have explored the effects of those changes on work outcomes. Especially, employees need to have the balance in working alone and working with others. The purpose of this study is to examine the effects of control over the physical environment by individuals and the effects of flexibility on individual and group work outcomes in the workplace, to examine the effects of distraction on work outcomes, and to suggest a interrelationships among variables. In this study, four hundred and nine questionnaires were collected from employees of three manufacturing corporations in Michigan, U. S. In order to explore the causal interferences among multiple relationships suggested in this study, path analysis was employed using Lisrel 8.54. The results indicated that control over the physical environmental features of the workplace positively influenced job satisfaction. The findings also supported the hypothesis that flexibility is positively related to task group cohesiveness. It was found that distraction was negatively associated with control and flexibility. However, it was not supported that control was positively associated with perceived performance. This study found control and flexibility in the workplace to be important. Some practical implications were suggested emphasizing that control and flexibility allow limited resources to be used in ways that permit individuals to work effectively within a changing work environment.

  • The manufacturing industry is the one with the most frequent industrial disasters, and it is important to study the safety climate recognized by workers in the industry in order to actively prevent industrial accidents. However, little research has been performed on the safety climate in workplaces felt by the workers in the manufacturing industry. The purpose of this study is to identify the factors affecting work environment safeness based on practical analysis via survey, and to establish the relation between safety performance factors and safeness of work environment. The survey was performed for workers in the manufacturing industry(n=228), and structural equations model analysis by using the AMOS 7.0 was performed in order to identify the fit of the research model and the causation among factors. According to the results of the analysis, the reliability and the model fit were appropriate for interpretation, and safety participation was shown to affect safeness of work environment more than safety compliance. The results of this study may serve as the reference for taking a measure to improve the level of safeness of the work environment felt by workers in the manufacturing industry.

  • The use of mobile office systems has been expanded due to the smartphones' rapid diffusion in Korea, and it has brought a new work environment that is different from traditional working patterns. In this study, the unique attributes of mobile office systems, such as ubiquity, usefulness, complexity, and insecurity, are examined along with the impact of these attributes on work overload and job stress. Based on transaction-based model of job stress, organizational support was applied as a stress inhibitor and also the moderator between work overload and job stress. The findings of this study show that ubiquity increases usefulness of mobile office systems; complexity increases both work overload and job stress; and insecurity increases job stress. Surprisingly, usefulness increases job stress, which means employees who perceive the efficiency of mobile office systems higher may feel more job stress. Organizational support for mobile office systems significantly shows the moderating effect, but no direct mitigating effect on job stress. The theoretical and practical implications in order to mitigate the side effects of mobile office systems based on the research findings are thoroughly discussed.

  • The management of daily work report is very important due to the variety of work trade and activities. Although various project management systems have been developed to effectively deal with various task in site, they are not in practical use due to the non-coorperative attitude of sub-contractors. This is the reason the system are not developed in the focus of sub-contractors, but main contractors and the detail information about daily work report is omitted or lost in the collection process by contractors. Therefore the purpose of this study was to propose the Web-based coordination system for daily work report between contractor and sub-contractors

  • Objectives: The purpose of this study is to provide basic data for elucidating the clinical experiences of nursing assistants working at dental clinics and for establishing the bases necessary for building a safe working environment for the staff at dental clinics. Methods: From March 28 to August 20, 2022, the study conducted in-depth interviews with nursing assistants working with dental hygienists in dental clinics. The collected data were analyzed using the phenomenological method. Results: The study analyzed the meanings associated with the dental clinical assistance work experiences of nursing assistants in dental clinics. A total of 98 semantic words and 9 sub-categories were extracted, which were ultimately categorized into 4 central meanings: 'imperfect reality', 'work without boundaries', 'putting oneself in someone else's shoes', and 'symbiosis'. Conclusions: The nursing assistants were exposed to an environment where they needed to perform delegated treatment procedures even when they lacked dental work competency. They recognized their gaps in learning and the necessity for designated roles as clinical assistants. Thus, it is necessary to review the allocation and expansion of the work roles of dental practitioners based on the practical and rational realities in dental practice.

The ontological understanding in the matter of truth in a work of art -on the subject of philosophical hermeneutics of H. G. Gadamer (예술 작품의 진리문제에 대한 존재론적 이해 - H. G. Gadamer의 철학적 해석학을 중심으로 -)

  • It's a matter of ontology rather than that of cognition and methodology to discuss a work of art in Gadamer's philosophy. In addition, he emphasizes the cognitive aspect of a work of art instead of comparing forms and contents of them. For that reason, he excludes aesthetic consciousness derived from Kant first and then makes away with Schiller's theory of aesthetic education. For Gadamer, the concept of truth does not mean accord or correspondence. It would rather be an encounter. This encounter is not axed on a specific time, but a continuous and historical one. Basically. a work of art guarantees this kind of an encounter. This encounter is not based on mutual agreement through an objective standard but on recognition with mutual understanding. Therefore, prejudice or tradition should be acknowledged and respected instead of being excluded. We have only to minimize difference between them through conversation. Gadamer's ontology of a work of art is based on such a ground. The function of a work of art is not only simple satisfaction of aesthetic senses but an object of interpretation, that is, a text by presenting a ground of truth through an agreement of situation. This text reveals its meaning in the situation of author-text-reader. The appearance of this meaning is nothing but the birth of truth. Symbol-allegory and classicism show how to express this kind of truth in a work of art. It is true that Gadamer's philosophical hermeneutics cannot be easily applied to interpret a concrete work of art because it just lays emphasis on the process of 'understanding' instead of a detailed analysis on an individual work. For that reason, he was criticized by some people because of this subjectivity of understanding. However, it's meaning could be changed according to the viewpoint on a work of art. There appears various structural approaches on a work of art in contemporary theory of art. Gadamer just asks the basis of such approaches instead of criticizing a specific one Therefore, a practical approach on individual work should be made separately and hermeneutics enriches the meaning of open-ending of each work of art.
