Friction tests were carried out in order to investigate the effects of temperature on the friction and wear behaviors between a PMMA film and a fused silica lens using a microtribometer. The friction forces on the PMMA film were measured under atmospheric condition as the temperature of the film was increased from 300 K to 443 K. The contact area between the film and the lens was observed. The tribological characteristics of the film were significantly changed as the temperature increased. The changes were discussed with the change of the film state from glassy to viscous flow. In addition, the results showed that the friction behavior can be varied with the thermal history of the PMMA film. Residual solvent in the PMMA film could emerge to the PMMA surface due to an additional heating and the solvent on the film surface decreased the friction force.

Objectives : To evaluate the association between working conditions and adverse pregnancy outcomes in Korea. Methods : We obtained data on health history, lifestyle, housework and Working conditions, such as shift work, hours standing, working time, job demand, lifting at work and at home, between August and September 2000, from self-reported questionnaires. A group of 344, occupationally active, pregnant women from 51 industries were studied. Of the women studied, 328 women were further interviewed by telephone between November 2000 and September 2001. Result : Compared with daytime work, shift work increased the risk for preform birth (an adjusted risk ratio of 2.74, 95% CI=1.02-2.62) and low birth weight (an adjusted risk ratio of 2.74,95% CI=1.02-2.02). A significantly increased risk was found for prolonged standing, with an adjusted risk ratio of preform births of 6.80 (95% CI=2.01-23.0). There were no significant differences in the incidence of spontaneous abortion between the occupational working conditions, with the enception of a previous history of spontaneous abortion. Conclusion : These findings suggest that maternal working conditions, such as shift work and prolonged standing, contribute significantly to preterm birth and low birth weight.

This study is to understand the architectural types and characteristics of the medical facilities during ancient period. The study is based on the research of the medical and architectural history. The medical or healthcare facilities are influenced by their social, cultural and conceptual idea, especially how they think about 'disease', 'cure' and the 'medicine'. As the results of the examination of this study can be summarized as followings. Firstly, Ancient medical facilities are classified into four types according to the ideas of 'disease' and 'cure' ; 1) God oriented facility 2) health welfare facility 3) treatment oriented facility 4) practice & educational facility. Secondly, there are three typical types of the spatial characteristics what modern hospitals have ; 1) nursing ward 2) treatment ward 3) hostel or hospice. And they are all assembled around the courtyard in common. Thirdly, their architectures are not 'designed' but 'derived' plan by reasonable other building types, and transformed by medical function. Fourthly, a consideration of the surrounding circumstances is the most important point to make the medical health facilities during ancient period.

Apparently light does exist even if it does not have certain form that an object might have. The history of architecture can be told as the history of light. As various master architects as well as scholars mentioned, light has been recognized as one of the most important aspects in perceiving space. Although there are complex multi dimensions in body sense and perception, experiencing space through light is preliminary formed by the outline to the degree of brightness. Light gives space specific and unique character by limiting or enlarging the space by wrapping an object or by reflection of material surfaces or by the intensity of light itself. It is fundamentally important to recognize the essential relationship between light and perception of space through various medias such as material, form, movement and so on. Three types of space perception and cognition by light that have been categorized after studying the most significant writings on light become the core method to further analyze the selected case projects. In this research, we will study how interior space is expressed through different light conditions with above mentioned characteristics and how such expressions can be applicable to the design of interior space.

Purpose: This study aimed to identify patterns of diagnosis and to explore risk factors for type 2 diabetes beyond the postpartum period in women with a previous history of gestational diabetes, and to identify differences in such risk factors between early and late-onset (aged <45 and ${\geq}45$). Methods: Using epidemiological data from the Korean Genome and Epidemiology Study, a retrospective analysis of 175 women with various timings of type 2 diabetes diagnosis was performed. Results: The average age ($42.6{\pm}10.6$) at type 2 diabetes diagnosis was earlier than the general population, and obesity was prevalent with marked weight gains around 35 years old. Longer duration of breastfeeding was observed in women with late-onset of type 2 diabetes. Conclusion: For prevention of type 2 diabetes, early intervention is required, and modifiable factors such as weight control and breastfeeding should be taken into consideration for intervention strategies.

There are numerous possible approaches to an investigation of the evolution of modern design. the intent of this study is to inquire into the history of 20th-century design as modern project. The French Revolution and the Industrial revolution at the end of 18th century brought about a wide spectrum of social and economic changes in Europe. The bourgeoisie took the leading part in these reforms and they attempted to establish the new aesthetic value of items of everyday use. The turning point in history led to the advent of modern design. This study attempts to provide a conceptual overview of significant stags in modern design's development this paper, it is hoped, will provide an opportunity to place modern design in a social and aesthetic context.

This study is a study on the effect of technical readiness factors on counselors' intention to use when applying AICC. AICC counselors experience improved customer service and emotional stability by receiving various monitor notification window services based on artificial intelligence algorithms such as customer counseling history, prohibited word control system, and customized counseling system. Accordingly, this study tried to verify using factors derived from technology readiness theory and technology acceptance theory among the factors affecting the intention to continue using AICC provided to counselors. To verify the research hypothesis, the causal relationship between variables such as Optimism, Innovativeness, Discomfort, Insecurity, and Technology Acceptance Theory, such as Team Support, Ease of Usage, and Innovation Resistance, was verified. As a result of empirical analysis, first, it was verified that Optimism has a positive (+) effect on Team Support and Ease of Usage, and Discomfort and Insecurity have a negative (-) effect on Ease of Usage and Team Support. Second, it was confirmed that Team Support and Ease of Usage had a positive effect on the Intention to use AICC. Based on the above empirical analysis results, the concepts of Technical Readiness were clearly proved, and in practical terms, AICC helped inquiry, quality evaluation, recording, and management of counseling history, ultimately increased corporate work efficiency.
