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.

There has been an enormous increasing trend of widening gap of social inequalities since economic crisis at the end of 1997 in Korea. Since then, Korean society has deteriorated in economic and social conditions; the unemployment rate, temporary or casual workers and absolute poverty have increased. This paper presents the origin of inequalities in work and health in Korea. The origin of inequalities in work begins with the relationship between the capitalist and labourers in the capitalist mode of production. The conception and execution are dissolved in the work process in the capitalist mode of production. Thus, captitalists become control over ther labour process from workers. An alienation of the work process from the workers. The distribution of work is the majour source if inequalities in many countries as well as Korea. This paper presents the increasing tendency of unhealthy states such as mortality, early death, morbidity, physical work load, workplace injury amongst the under-privileged: ordinary workers, unemployed people, casual workers and socially deprived people in Korea.

BIM(Building Information Modeling) ordering manuals and guidelines are diffused with the recent BIM activation. However, it is causing drawbacks such as an increase of work at each design stage and a decline of BIM application level that the standard of making up and managing BIM is vague and it includes comprehensive meaning. Therefore, this study aims to secure BIM work standard by establishing BIM making-out standard based on LOD(Level of Detail) classification considering domestic design process. It compared each definition of LOD by analyzing domestic and foreign BIM guideline examples, and figured out insufficiency of existing domestic and foreign design process and BIM guidelines. Moreover, it drew architects' work articles for promoting the progression of the efficient design process, and analyzed BIM requirements on design process, dividing BIM application scale by field. Through this analyzing process, it finally established BIM making-out standard classified by design process. The effects of establishing BIM making-out standard would include improving a division of labor and cooperation environment by creating integrated BIM model on design stages, advancing work efficiency by preventing a repetition and an increase of work, and upgrading project completeness and design quality. Besides, it can secure BIM work standard by clarifying responsibility for working steps. BIM making-out standard established by this study will contribute to developing the future BIM work standard document and BIM guideline as a data base.

The subjects of this study were 285 working couples with children. The research tool was questionnaires which consisted of general characteristics of the subjects and multidimensional measure of work-family spillover scale. For data analysis, factor analysis, Cronbach ${\alpha}$, t-test, and paired t-test were performed. Based on analysis of data using factor analysis, three-distinct work-family spillover process can be measured for both wife and husband, time interference, psychological distraction, and energy depletion and the multidimensional measure of work-family spillover is able to validly assess different domains of family life into which spillover occurs. The main results of this study were as following: First, there were significant differences in work-family spillover process according to sex. In work${\rightarrow}$family spillover, male more experienced negative time interference than female, on the other hand, in family${\rightarrow}$work spillover, female more experienced negative energy depletion than male. Second, there were significant differences in domains which work-family spillover occurs according to sex. Male more experienced negative work${\rightarrow}$family spillover than female in marital relations and parent-child relations domains while female more experienced negative family${\rightarrow}$work spillover than male in parent-child relations and home management domains. Third, there were significant differences between wife and husband in work-family spillover process. In work${\rightarrow}$family spillover, husband more experienced negative time interference than wife, on the other hand, in family${\rightarrow}$work spillover, wife more experienced negative energy depletion than husbands. Forth, there were significant differences between wife and husband in domains which work-family spillover occurs. Male more experienced negative work${\rightarrow}$family spillover than female in marital relations, parent-child relations, and leisure life domains. And while husband more experienced negative family${\rightarrow}$work spillover than wife in parent-child relations, wife more experienced negative family${\rightarrow}$work spillover than husband in home management domains.

In the plastic extrusion process, product quality is influenced by work condition for temperature of cylinders and dies. The work conditions are various, so it is difficult to standardization of the work conditions. Therefore, the work conditions are depended on the workers of experience and skill. In the plastic extrusion process, it has five control heating points on the cylinder and three control heating points on the die. In addition, there is one control point on the extrusion process. It is extrusion speed. In this case, we don't know how these affect product quality. We structure the multiple linear regression equation with the temperature of cylinders and dies as independent variables and the product weight as dependent variable. We solve this equation using statistic computer package named Juse-Qcas.
